1 Wed Jan 15 09:56:16 1992 Fred Fish (fnf at cygnus.com)
3 * solib.c (solib_add_common_symbols): Only compile in when not
4 using SVR4 style shared libraries.
6 Tue Jan 14 22:34:00 1992 Fred Fish (fnf at cygnus.com)
8 * dwarfread.c (locval): Add offreg flag to indicate location
9 values that are computed off a base register.
11 * dwarfread.c (new_symbol): Rework TAG_global_variable and
12 TAG_local_variable cases to account for static variables
13 within function scopes.
15 Tue Jan 14 12:28:52 1992 Stu Grossman (grossman at cygnus.com)
17 * inflow.c: remove #include <sys/dir.h>. Not necessary, and
18 doesn't exist on some systems.
20 * infrun.c (wait_for_inferior!!!!): Prevent gdb from hanging when
21 nexting over recursive function calls.
23 * target.c (target_read_string): Create this routine to read null
24 terminated strings from the target. It deals with running off the
25 end of memory elegantly as well. solib.c (find_solib): Use
26 target_read_string() to avoid problems with running off the end of
29 * inflow.c (child_terminal_info): #ifdef TIOCPGRP around lines
30 that reference pgrp_inferior.
32 Mon Jan 13 14:57:11 1992 Per Bothner (bothner at cygnus.com)
34 * tm-mips.h: Removed BLOCK_ADDRESS_ABSOLUTE, now that
35 mips-tfile has been hacked to act more "traditionally."
36 * dbxread.c: Fixed typo in comment.
38 Sun Jan 12 13:08:36 1992 Per Bothner (bothner at cygnus.com)
40 * mips-tdep.c (mips_skip_prologue): Add some number of
41 'sw' instructions before 'addiu' adjusts the stack.
43 Fri Jan 10 13:47:06 1992 Fred Fish (fnf at cygnus.com)
45 * dwarfread.c (start_symtab, end_symtab, scopecount, openscope,
46 freescope, buildblock closescope, record_line, add_symbol_to_list,
47 gatherblocks, make_blockvector): Extensive changes to switch
48 to generic symbol table building code in buildsym.c. Remove
49 scope tree structures and functions, symbol table building
50 functions, and lots of other small changes.
52 * dwarfread.c: Add new macros GCC_PRODUCER and STREQN. Remove
53 GCC_COMPILED_FLAG_SYMBOL and GCC2_COMPILED_FLAG_SYMBOL.
55 Tue Jan 7 13:09:57 1992 Stu Grossman (grossman at cygnus.com)
57 * buildsym.c (cleanup_undefined_types): Add support for enums.
58 This fixes the 'GDB internal error. cleanup_undefined_types with
61 Sun Jan 5 09:47:50 1992 Stu Grossman (grossman at cygnus.com)
63 * dbxread.c: detect gcc2 compilations.
65 Thu Jan 2 15:07:41 1992 John Gilmore (gnu at cygnus.com)
67 * sparc-pinsn.c: Rename bitfields that overlap with macro names
68 in ../include/opcode/sparc.h.
70 Wed Jan 1 04:29:00 1992 Fred Fish (fnf at cygnus.com)
72 * Makefile.in: Change tm-svr4.h to tm-sysv4.h. Change xm-svr4.h
73 to xm-sysv4.h. Split OPCODE_DIR into OPCODE_DIR1 and OPCODE_DIR2
74 to reflect actual locations of opcode files, so TAGS target will
77 * i386-tdep.c: Change an erroneous 'm68k' reference to 'i386'.
79 * i386-tdep.c (supply_fpregset, fill_fpregset): Remove m68k
82 * m68k-tdep.c (supply_fpregset, fill_fpregset): Fix array
83 dereferencing to access the correct elements.
85 * valops.c (value_addr): Declare return type of external func
88 * xcoffread.c: Undefine next_symbol_text before redefining it.
90 Mon Dec 30 10:57:02 1991 Per Bothner (bothner at cygnus.com)
92 Mainly stuff to improve handling of TYPE_CODE_REF values.
93 * valops.c (value_addr): If taking the addres of a
94 TYPE_CODE_REF, just cast the object to the corresponding
95 TYPE_CODE_PTR. This yields correct C++ semantics, and
96 preserves the location information, which has the nice effect
97 that &(&R) given the location containing R.
98 * values.c (value_copy): Make non-static (used by value_addr).
99 * eval.c (evaluate_subexp_for_address): Use the default
100 scheme (with value_addr) for a variable if it has TYPE_CODE_REF.
101 * valops.c (value_addr), eval.c (evaluate_subexp_for_address,
102 evaluate_subexp_with_coercion): Factor out some common
103 expressions into variables, for easier reading.
104 * findvar.c (locate_var_value): Remove code to handle
105 TYPE_CODE_REF - it should no longer be needed.
106 * valops.c (value_assign): Do a COERCE_REF on the
107 destination operand, for correct C++ semantics.
108 * valarith.c (value_x_binop): Ditto: De-reference C++
109 references in the arguments.
110 * valops.c: ANSI-fy: bcopy->memcpy, bzero->memset.
112 Sat Dec 28 11:30:26 1991 Per Bothner (bothner at cygnus.com)
114 * dwarfread.c, coffread.c: Use INIT_CPLUS_SPECIFIC.
115 * symtab.c (gdb_mangle_name): Recognize and handle
116 constructors specially.
117 * symtab.c (check_stub_method): Test for failure from
118 cplus-demangle by calling error() instead of seg-faulting ...
120 Fri Dec 27 22:21:30 1991 Fred Fish (fnf at cygnus.com)
122 * defs.h: Add definition of null_cleanup()
124 * procfs.c: Many small changes to add base support for a new
125 "info proc" command (currently only printing of the address
126 space mapping is implemented) and allow iteration over the
127 address space mapping, calling an arbitrary function for each
128 mapping (used for shared library support).
130 * solib.c: Change all ifdefs that checked for "sun" to check
131 for "!SVR4_SHARED_LIBS" instead. Rewrite lookup_base() to
132 handle locating the debug base address even when not currently
133 stopped at the dynamic linker entry point.
135 * utils.c: Add null_cleanup() as a known function that does
136 nothing to serve as a base for possibly long cleanup chains
137 with no specific "first cleanup" to serve as an anchor.
139 * xm-sysv4.h: Add define of SVR4_SHARED_LIBS
141 Fri Dec 27 10:11:33 1991 Per Bothner (bothner at cygnus.com)
143 * arm-opcode.h, m88k-opcode.h, pn-opcode.h, np1-opcode.h,
144 pyr-opcode.h, tahoe-opcode, vax-opcode.h: Removed -
145 these are all essentially the same as the versions
146 in ../include/opcode. The remaining *-opcode.h here
147 are not quite so obviously the same, and need study.
148 * arm-pinsn.c, gould-pinsn.c, m88k-pinsn.c, pyr-pinsn.c,
149 tahoe-pinsn.c, vax-pinsn.c: Change so these include
150 opcode/FOO.h (actually ../include/opcode/FOO.h)
151 instead of the recenntly departed opcode-FOO.h files.
152 * sparc-pinsn.c: Now that we're using the much tighter
153 opcode table in ../include/opcode/sparc.h, we shouldn't
154 need to sort the opcodes before dis-assembly.
156 * symtab.h, symmisc.c: Make cplus_struct_default be const.
157 * symtab.h, buildsym.c: Add and use INIT_CPLUS_SPECIFIC macro.
158 * symmisc.c: Remove unused 'nfields' variable.
159 * buildsym.h: Add extern decl of unknown_symtype_complaint,
160 since it used used by partial-stab.h (included two places).
161 * partial-stab.h: Re-arrange DBXREAD_ONLY #ifdefs so that
162 we should never hit the default case (until new stab codes
163 are added). Hence, we can leave the complaint in the
164 default case in even when DBXREAD_ONLY is off.
165 * partial_stab.h: Recognize a pair of N_SO stabs (one for the
166 directory, one for the filename proper) without peeking ahead.
167 * dbxread.c, mipsread.c: Because of previous change, don't need
168 ugly CHECK_SECOND_N_SO macro.
169 * buildsym.h, dbxread.c, mipsread.c: Make next_symbol_text a
170 macro that invokes a function pointer in next_symbol_text_func.
171 * mipsread.c: Added comments various places to
172 explain what is going on.
173 * mipsread.c (parse_symbol): Support the new (SGI-specific?)
174 symbol types stStruct, stUnion, and stEnum.
175 Also, some fixes in the code for dealing with tags.
176 * mipsread.c: Change handling of startup_file_start and _end
177 - now just use the textlow and texhigh of a psymtab
178 to check if we've found the startup-file.
179 * mipsread.c: Replace s_idx by global cur_sdx in many places.
180 This is so mips_next_symbol_text can get at it.
182 Thu Dec 26 19:52:01 1991 Fred Fish (fnf at cygnus.com)
184 * dbxread.c, symmisc.c: Move add_psymbol_to_plist() from
185 dbxread.c to symmisc and change name to add_psymbol_to_list.
186 Ditto for add_psymbol_addr_to_plist(). Also expand their
187 body to not use ADD_PSYMBOL_VT_TO_LIST.
189 * dwarfread.c: Remove add_psymbol_to_list() and convert usages
190 to the ADD_PSYMBOL_TO_LIST macro.
192 * ieee-float.c: Change "#ifdef DEBUG" to "#ifdef IEEE_DEBUG"
193 to avoid collision with the DEBUG for ADD_PSYMBOL_VT_TO_LIST.
195 * partial-stab.h, symfile.h: Move definitions of the macros
196 ADD_PSYMBOL_TO_LIST and ADD_PSYMBOL_ADDR_TO_LIST from
197 partial-stab.h to symfile.h. They aren't stab specific.
198 Change ADD_PSYMBOL_VT_TO_LIST to use memcpy rather than strncpy.
200 Tue Dec 24 11:38:08 1991 John Gilmore (gnu at cygnus.com)
202 * Makefile.in: Roll VERSION to 4.3.2.
204 Mon Dec 23 13:54:35 1991 Per Bothner (bothner at cygnus.com)
206 * m68k-opcode.h, mips-opcode.h, sparc-opcode.h: Deleted.
207 * m68k-pinsn.c, mips-pinsn.c, sparc-pinsn.c:
208 Include <opcode/FOO.h> instead of <FOO-opcode.h>.
210 * symtab.h, symtab.c, coffread.c, dwarfread.c, symmisc.c,
211 dbxread.c: The TYPE_CPLUS_SPECIFIC structure is now only
212 allocated when it is needed. Until it is needed, it points
213 to a shared statically allocated structure.
215 * buildsym.h, buildsym.c, dbxread.c: Remove the kludgy code
216 in read_ofile_symtab to recognize two initial N_SO stabs,
217 and let process_on_symbol handle it. This is cleaner, more
218 efficient, and lets mipsread.c share the same code.
220 * symfile.h, partial-stab.h: Move ADD_PSYMBOL_VT_TO_LIST
221 and related macros to here ...
222 * dbxread.c: ... from here.
223 * symmisc.c: Move the "overflow" handling from
224 ADD_PSYMBOL_VT_TO_LIST macro into new function extend_psymbol_list.
225 * dwarfread.c: Re-write add_psymbol_to_list to use
226 ADD_PSYMBOL_VT_TO_LIST macro.
228 * mipsread.c: Extend mipsread.c to handle stabs-style symbols
229 encapsulated in ecoff symbols. This enable full g++ debugging.
230 * partial-stab.h: Move the code for pre-scanning symbols
231 and building psymtabs to an include file, out from dbxread.c.
232 This way, the same code can also be used by mipsread.c.
233 * dbxread.c, buildsym.h: Various changes to allow some functions
234 to be used by mipsread.c (also some arguable stylistic changes).
236 * tm-mips.h: Define BLOCK_ADDRESS_ABSOLUTE, at least for now,
237 since mips-tfile puts relocatable addresses into LBRAC/RBRAC
240 * mipsread.c: Replace code to handle ambiguous tag blocks.
241 Instead of allocating a TYPE_CODE_UNDEF, guess (by looking
242 at types and offsets) if a tag is a struct, union, or enum.
243 Still patch it later if we find out for sure.
244 * mipsread.c: In various ways, replace Forin's
245 ideo-syncratic code by code that fits better with the
246 rest of gdb, for both stabs-based and ecoff-based symtabs.
247 E.g. use end_psymtab; don't do extra passes over FDR table to
248 pre-partition global data; don't use external symbols to
249 create static/global symbols (just put them in the
250 misc_vector); use ADD_PSYMBOL_TO_LIST macro; don't
251 sort psymtabs or symtabs; use obstacks more.
253 * symtab.c, mipsread.c, dbxread.c, buildsym.c:
254 ANSIfy: Replace bcopy by memcpy, bzero by memset.
256 Sun Dec 22 19:31:04 1991 Fred Fish (fnf at cygnus.com)
258 * solib.c (locate_base): Fix uninitialized variable that was
259 causing return of random value to callee.
261 * config/mh-amix, config/mh-i386v4: Change to find alloca by
262 compiling and linking alloca.c, even when it is not strictly
263 required. Also arrange to link with -ltermlib rather than
266 * Makefile.in: Move TERMCAP definition to prior to inclusion
267 of host makefile fragments so it can be overridden.
269 Fri Dec 20 16:33:39 1991 John Gilmore (gnu at cygnus.com)
271 * xcoffread.c (read_symbol_lineno): Logic error in incrementing
272 symbol table entry number. (From Metin Ozisik.)
274 Fri Dec 20 11:36:38 1991 Fred Fish (fnf at cygnus.com)
276 * config/mh-i386v4: Change XM_CLIBS to "-lc /usr/ucblib/libucb.a"
277 so compiles with native compilers (without builtin alloca) can
278 pick up the version from the bsd emulation library. However, we
279 search the standard C library first so we don't pick up lots of
280 other broken stuff from libucb.a, that we *don't* want.
282 * configure.in, tm-amix.h, tm-i386v4.h, xm-amix.h, xm-i386v4.h:
283 Change svr4 references to sysv4.
285 * source.c: Move declaration of external function index to
286 front of file so it is in scope for all references.
288 * utils.c (error, fatal): Make definitions consistent with
289 defs.h declarations (declared as "volatile void").
291 Fri Dec 20 10:55:36 1991 John Gilmore (gnu at cygnus.com)
293 * rs6k-opcode.h: Bugfix sfe and stbrx. By Al Kossow.
295 Wed Dec 18 17:09:06 1991 Stu Grossman (grossman at cygnus.com)
297 * command.h, defs.h, eval.h, expression.h, remote-sa.sparc.c,
298 sparc-tdep.c, symtab.h, target.h, value.h, vx-share/ptrace.h,
299 vx-share/xdr_ptrace.h, vx-share/xdr_rdb.h: ANSIfy enums.
301 Mon Dec 16 12:31:46 1991 Fred Fish (fnf at cygnus.com)
303 * config/mt-amix, config/mt-i386v4: Add solib.o to TDEPFILES
304 for these SVR4 systems.
306 * symfile.c (symbol_file_add): When verbose is set, print
307 the names of files from which symbols are being loaded, as
308 when from_tty is true.
310 * solib.c: Completely reorganized (rewritten) to support
311 SVR4 shared libraries in a manner very close to the original
312 SunOS implementation. This support is expected to change and
313 become more general at some future time. The SVR4 version
314 does not yet work for attached processes, for example.
316 * dwarfread.c: Arrange in dwarf_build_psymtabs() for the
317 relocation address to be valid whether or not symbols are
318 being read from a shared library or an executable. Use the
319 relocation address recorded in the psymtab when reading
320 full symbol tables (in read_ofile_symtab). Ensure that the
321 relocated address ranges are recorded in partial symtabs.
323 * elfread.c: Add new function elf_interpreter() to return the
324 string from the ELF ".interp" section. This is the interpreter
325 that the kernel tries to run and feed the executable to.
326 Expand arguments to record_misc_function to include a type arg.
327 Modify elf_symtab_read() to supply the type arg, and to do symbol
328 relocations for symbols read in from shared libraries.
330 * procfs.c: Add new functions proc_base_address() and
331 proc_address_to_fd(), used by shared library support.
333 * tm-svr4.h: Add macros to support SVR4 shared libraries.
334 Definitions for SOLIB_ADD, SOLIB_CREATE_INFERIOR_HOOK,
335 CLEAR_SOLIB, and DISABLE_UNSETTABLE_BREAK.
337 Fri Dec 13 20:11:26 1991 John Gilmore (gnu at cygnus.com)
339 * infrun.c, remote-eb.c, remote-nindy.c, remote-vx.c: Remove
340 unused START_INFERIOR_HOOK.
342 * remote-eb.c: Change timeout to 24 seconds (*10 fits in byte)
343 to account for slow loading from floppies.
344 (eb_create_inferior): New fn, from eb_start and
345 nindy_create_inferior.
346 (eb_close): Only use log_file if nonzero.
347 (eb_xfer_inferior_memory): If not writing, then read!
348 (eb_read_inferior_memory, eb_write_inferior_memory): Return length.
349 (eb_kill): A new no-op.
350 (eb_mourn_inferior): Remove breakpoints, then generically weep.
352 Fri Dec 13 16:09:23 1991 Fred Fish (fnf at cygnus.com)
354 * breakpoint.c, findvar.c, infrun.c, putenv.c, stack.c: Fix
355 miscellaneous comparisons of integer with NULL that elicit
356 compiler warnings about comparison of integer with pointer, when
357 NULL is ((void *) 0) rather than just a bare 0.
359 Wed Dec 11 13:02:58 1991 John Gilmore (gnu at cygnus.com)
361 * breakpoint.c (breakpoint_re_set_one): Disable each breakpoint
362 while we reset it, in case of problems. Print breakpoint number
365 * buildsym.c (read_struct_type): Avoid sun3 compiler bug with
368 * source.c (find_source_lines): If getting file mod time fails,
371 * target.c (target_xfer_memory): If errno is set, return it,
374 Tue Dec 10 04:07:22 1991 K. Richard Pixley (rich at rtl.cygnus.com)
376 * Makefile.in: infodir belongs in datadir.
378 Sun Dec 8 21:13:33 1991 Michael Tiemann (tiemann at sphagnum.cygnus.com)
380 * symtab.h (struct fn_field): Add new fields `is_private',
381 `is_protected', `is_stub', making room by reducing the size of
383 (struct fn_fieldlist): Delete the fields `private_fn_field_bits'
384 and `protected_fn_field_bits'.
385 (TYPE_FN_{PRIVATE,PROTECTED}_BITS): Deleted.
386 (SET_TYPE_FN_{PRIVATE,PROTECTED}): Deleted.
387 (TYPE_FN_{PRIVATE,PROTECTED}): Deleted.
388 (TYPE_FN_FIELD_{STUB,PRIVATE,PROTECTED}): New macros.
389 * valops.c, valprint.c, symtab.c: All callers updated.
391 * buildsym.c (read_struct_type): Delete the `visibility' field
392 from `struct next_fnfield', and rework code so that visibility
393 info is stored into the fn_field directly. Also, hacked to set
394 TYPE_FN_FIELD_STUB for both static and normal member functions.
396 Sat Dec 7 18:13:11 1991 Fred Fish (fnf at cygnus.com)
398 * i386-tdep.c: Fix a problem on i386 systems where buffered code
399 stream access was failing to take into account the minimum size
400 granularity of the code section. For now, the buffering is simply
401 disabled. There is a similar problem in the i386 disassember code
402 that has not yet been fixed (FIXME).
404 * gmalloc.c: Use macros to hide some of the ugly casting required
405 in the previously applied fix for pointers with high bits set.
407 Sat Dec 7 16:49:35 1991 John Gilmore (gnu at cygnus.com)
409 * Makefile.in: Roll VERSION to 4.3.1.
411 Sat Dec 7 04:12:35 1991 John Gilmore (gnu at cygnus.com)
415 * Makefile.in: Roll VERSION to 4.3
416 * README, TODO, WHATS.NEW, depend: Update.
418 * inflow.c (terminal_inferior): Avoid error msg if attached.
420 * gmalloc.c: Fix bug that causes malloc & free to
421 fail on systems where pointers have the high bit set (0x800efcf0
422 for example). The problem is that the difference between two
423 pointers is a signed integer, so the computation
425 (char *) 0x800efcf0 - (char *) 0
427 yields a negative value. The sign of the result of the modulus
428 operator is machine dependent for negative operands, thus it is
429 possible for it to end up negative. From Fred Fish.
431 Sat Dec 7 00:00:15 1991 K. Richard Pixley (rich at rtl.cygnus.com)
433 * Makefile.in: install using INSTALL_PROGRAM and INSTALL_DATA.
434 added clean-info. added some standards.text support and made it
435 look like our other Makefiles.
437 * configure.in: mark this directory target dependent. configure
438 now runs entirely in objdir so make existence tests and
439 references against ${srcdir}.
441 Fri Dec 6 08:30:36 1991 Fred Fish (fnf at cygnus.com)
443 * dwarfread.c (enum_type, struct_type): Fixes for opaque and
444 anonymous enumerations, structures, and unions. Now passes all
445 the current gdb test suite tests.
447 Thu Dec 5 22:46:13 1991 K. Richard Pixley (rich at rtl.cygnus.com)
449 * Makefile.in: idestdir and ddestdir go away. Added copyrights
450 and shift gpl to v2. Added ChangeLog if it didn't exist. docdir
451 and mandir now keyed off datadir by default.
453 Thu Dec 5 21:53:21 1991 John Gilmore (gnu at cygnus.com)
455 * symtab.c (decode_line_1): If SKIP_PROLOGUE leaves us in
456 mid-line, be more careful about possibly advancing to the next line.
458 Thu Dec 5 18:59:51 1991 Michael Tiemann (tiemann at cygnus.com)
460 * cplus-dem.c (cplus_demangle): Call `string_need' when
461 null-terminating a partially-computed string.
463 Thu Dec 5 18:19:43 1991 Fred Fish (fnf at cygnus.com)
465 * dwarfread.c (enum_type): Build a correct TYPE_NAME, add a
466 symbol to the symbol table for each member of the enum.
468 * dwarfread.c (struct_type): Build a correct TYPE_NAME.
470 * dwarfread.c (add_enum_psymbol): New function to extract enum
471 member names and add them to the partial symbol table while
472 building partial symbol tables.
474 Thu Dec 5 17:31:05 1991 John Gilmore (gnu at cygnus.com)
476 * symtab.c (check_stub_method): Must allocate two extra argument
477 slots (one for `this', one for arglist terminator).
479 Thu Dec 5 10:51:05 1991 Fred Fish (fnf at cygnus.com)
481 * inflow.c (child_terminal_info): Supply missing '"' character.
483 * buildsym.c (define_symbol): Supply missing parenthesis.
485 Thu Dec 5 03:34:21 1991 John Gilmore (gnu at cygnus.com)
487 * coredep.c (fetch_core_registers): Fencepost error. Fixed by
488 Jay Lepreau <lepreau@cs.utah.edu>.
490 * inflow.c: Remember whether GDB has a terminal. Avoid switching
491 terminals back and forth if we don't have one.
493 * c-exp.y (parse_number): Zero is not an unsigned int constant!
494 * dbxread.c (read_dbx_symtab): Enum type numbers can be in (1,2) form.
496 Improve type parsing.
497 * buildsym.c (define_symbol, read_range_type): Add
498 long_kludge_name that passes the names of range types being
499 defined, down to where we must choose between 'int' and 'long'
500 variants. This fails on Sun C anyway since the compiler itself is
501 confused between int and long.
502 (read_array_type, cleanup_undefined_types): Correct the size of
503 array type whose element-type size isn't immediately known.
505 Early preparation to blow away many builtin types, building them
506 on the fly as needed. Don't compare types to builtin types with
507 ==; examine the relevant fields instead.

509 * buildsym.c (define_symbol, case 'p'): Avoid ==.
510 * valops.c (value_arg_coerce): Avoid ==. Don't assume host and
511 target types are the same.
512 * valprint.c (val_print): I finally understand arrays, remove FIXME.
514 * symmisc.c (printpsyms_command): Reduce redundancy, and put all

517 Wed Dec 4 21:05:30 1991 Fred Fish (fnf at cygnus.com)
519 * dwarfread (enum_type): Arrange for the order of enumeration
520 members to match the source code order; not the order in the
521 Dwarf information, which is explicitly reverse order.
523 Wed Dec 4 18:24:39 1991 John Gilmore (gnu at cygnus.com)
525 * main.c (input_from_terminal_p): Check whether GDB has a

548 since it is not needed and can cause errors when examining ".o"s.
549 (read_coff_symtab, decode_base_type): Use complain, not printf.
550 Print symbol name, not its number.
551 Remove "#if defined(clipper) #define BELIEVE_PCC_PROMOTION", which
552 someday should go in a clipper target config file.
554 * symfile.c (compact_misc_function_vector): Handle empty vector.
555 (complain, clear_complaints, syms_from_objfile): Fix complaint
557 * xcoffexec.c: Change syms_from_objfile caller.
559 * sparc-xdep.c: Force tm-file as tm-sparc.h, to make it compile
560 when configured for cross debugging. FIXME, this needs a more
563 Mon Dec 2 11:04:05 1991 Per Bothner (bothner at cygnus.com)
565 * mips-tdep.c (init_extra_frame_info): Float register
566 'i' has gdb-internal number 'FP0+i', not '32+i'.
567 * mipsread.c (new_symbol): Translate g++ special
568 symbol "$t" to "this".
570 Sat Nov 30 21:29:55 1991 Steve Chamberlain (sac at cygnus.com)

600 target dependent support functions for the SVR4 /proc register
603 * dwarfread.c (enum_type, struct_type): Expand recognized
604 compiler generated tags to include symbols beginning with '.' as
607 * symtab.c (sources_info): Change simple printf of error message

618 Fix bugs in C++ debugging.
620 * symtab.h: target_type is not used in record types.
621 Eliminate TYPE_MAIN_VARIANT and TYPE_NEXT_VARIANT. Eliminate
622 lookup_method_type. Add TYPE_TYPE_SPECIFIC macro.

625 allocate one in symbol_obstack when we need one.
626 (allocate_stub_method): Build stub in symbol_obstack.
627 (check_stub_method): Move here from values.c. Don't deallocate

632 Change some C++ parsing error()s to complain()ts.
633 * buildsym.c, findvar.c, printcmd.c, symtab.c: Make unions and
634 structs have the same representation and work the same as far as
636 * buildsym.c, symtab.c, values.c: Remove all references to
637 TYPE_MAIN_VARIANT and TYPE_NEXT_VARIANT.
639 * valops.c: Improve comments and indentation. Only call
640 check_stub_method when the stub flag is on.
641 * valprint.c: Fix or mark minor bugs and unportabilities.
643 * coffread.c (anonymous unions): Allocate a cplus structure.
645 * mipsread.c: Eliminate "template" types. Build new, real
646 types whenever we need them. Allocate cplus structures as needed.
647 Bulletproof the type parsing a bit more. Mark storage leaks.
648 (parse_type): Copy TYPE_TYPE_SPECIFIC when copying a real type
649 on top of a partial type.
651 Fri Nov 22 16:39:57 1991 John Gilmore (gnu at cygnus.com)
653 * inflow.c (terminal_inferior): Check the results of ioctl's, and
654 print a message if any of them fail.
655 (terminal_ours_1): Store result of ioctl's for debugging, but
656 don't print (the terminal isn't ours...).
658 * tm-tahoe.h (FRAME_ARGS_ADDRESS): No need to offset from frame
661 * m2-exp.y (MAX, MIN): Rename to MAX_FUNC, MIN_FUNC to avoid
662 conflicts with system header files.
664 Fri Nov 22 08:27:40 1991 John Gilmore (gnu at cygnus.com)
666 * Roll VERSION to 4.2.95.
668 * buildsym.c, coredep.c, mem-break.c, xcoffread.c: Put <stdio.h>
669 first, before defs.h.
670 * config/mh-i386sco: Override compiler to gcc, print warning.
671 * configure.in: Handle i386-none-aout rather than i386-aout-none.
672 * infptrace.c, language.h, utils.c: Lint.
673 * m2-exp.y: #undef MAX and MIN in case system includes set them.
674 * xm-tahoe.h: Set HOST_BYTE_ORDER. Include system versions of
675 {BIG,LITTLE}_ENDIAN and the INT_MAX family first, to avoid
676 redefinition warnings.
677 * defs.h: Reorder things so that the xm-file gets first crack
678 at #define's, followed by defs.h and then the tm-file.
679 * Makefile.in: Remove spaces after 'ignore exit code' - flags.
680 Late-model BSD 'make's don't cope with them.
682 Thu Nov 21 23:48:56 1991 John Gilmore (gnu at cygnus.com)
684 * Makefile.in: Roll new files into various lists.
686 Thu Nov 21 18:26:11 1991 Fred Fish (fnf at cygnus.com)
688 * dwarfread.c (struct_type): Must initialize the c++ specific
689 portion of union types as well as struct types, since gdb attempts
690 to reference the c++ specific info for both types.
692 Thu Nov 21 10:23:52 1991 John Gilmore (gnu at cygnus.com)
694 * Makefile.in: Roll VERSION to 4.2.90.

716 Wed Nov 20 18:35:56 1991 John Gilmore (gnu at cygnus.com)
718 * Remove gdb/hp-include. Support for HP a.out oddities should be
719 in BFD, not in GDB. Move gdb/hp-include/a.out.h to include/a.out.hp.h.
721 * infptrace.c, tm-sun386.h: Cashier <a.out.gnu.h>, remove refs.
723 * configure.in, xconfig, tconfig, Makefile.in, doc/gdbint.texinfo:
724 Makefile fragments for various hosts and targets now come from
725 gdb/config/mh-* and gdb/config/mt-*. This is for consistency with
728 * rs6000-pinsn.c, rs6k-opcode.h: Clean up.
729 * rs6k-opcode.def: Delete.
731 Wed Nov 20 05:04:40 1991 Fred Fish (fnf at cygnus.com)
733 * dwarfread.c: Recognize obsolete form of AT_element_list
734 attribute still used by at least one AT&T compiler, and possibly
737 Tue Nov 19 07:53:55 1991 Fred Fish (fnf at cygnus.com)
739 * dwarfread.c (enum_type, struct_type): Ignore names invented by
740 helpful compilers for anonymous structs, unions, and enums.
742 * c-exp.y, m2-exp.y: Add defines for yymaxdepth, yy_yys, and
743 yy_yyv, so multiple parsers produced by SVR4 versions of yacc
744 can coexist in the same executable without collision.
746 * symtab.h: Add declaration for lookup_template_type() to kill
747 compiler warnings about conversions from int to pointer.
749 Mon Nov 18 17:45:18 1991 Fred Fish (fnf at cygnus.com)
751 * procfs.c: Move inclusion of defs.h to before param.h, as in
752 all the other source files that include both. This is required
753 to supply some typedefs that are used in files included by param.h.
755 * m68k-tdep.c (m68k_skip_prologue): Add generic m68k support for
756 skipping function prologues, ala the other cpu families (i386,
757 mips, m88k, etc). Add the ability to skip movm and fmovm
758 instructions in the prologues. Still needs support for profile
759 (-p compiled) prologue sequences (FIXME).
761 * tm-68k.h: Change SKIP_PROLOGUE macro to use the new generic
762 m68k prologue skipping function by default.
764 * tm-altos.h, tm-isi.h: Continue to use the old definition of
767 Mon Nov 18 15:12:45 1991 John Gilmore (gnu at cygnus.com)
769 * Makefile.in: Remove tdesc stuff, and extra blanks before colons.
770 * blockframe.c: Remove tdesc-related code. Default
772 * infrun.c: Remove tdesc-related code.
773 * m88k-tdep.c (frame_chain_combine, init_frame_pc): Remove copies
774 of defaultable things.
775 * tm-m88k.h: New file, common to all Moto 88k target configs.
776 Derived from tm-delta88.h.
777 * tm-delta88.h: Use it.
778 * xm-m88k.h: Common file for 88K hosts. Remove obsolete stuff.
779 * xm-delta88.h: Use it.
780 * tm-*.h: Remove FRAME_CHAIN_COMBINE macros, since all are
782 * coffread.c: Remove tdesc stuff.
783 * tconfig/delta88, tconfig/m88k: Remove tdesc stuff.
784 * xconfig/m88k: Rename tm-88k.h to tm-m88k.h.
786 Mon Nov 18 13:51:37 1991 Per Bothner (bothner at cygnus.com)
788 * source.c (open_source_file): If openp fails, try again
789 using just the base (non-directory) part of the filename.
790 This solves various annoying problems, such as when the
791 source was compiled with an absolute pathname - and the
792 source files have moved. Or if the source was compiled
793 using a relative pathname, it can be more convenient
794 to just specific the source directory to the dir command.
796 Mon Nov 18 00:04:41 1991 Fred Fish (fnf at cygnus.com)
798 * cplus-dem.c (munge_function_name): Add missing third arg to
799 instance of call to do_type().

802 AT_deriv_list, AT_loclist, AT_incomplete, AT_const_data,
805 Sun Nov 17 16:20:53 1991 Michael Tiemann (tiemann at rtl.cygnus.com)
807 * symtab.h (struct type): Moved C++-specific fields into new type
808 `struct cplus_struct_type'. Now takes 10% less memory. Many
810 * symtab.c (init_type): Don't set fields belonging to
811 TYPE_CPLUS_SPECIFIC unless TYPE is TYPE_CODE_STRUCT.
812 * buildsym.c (read_type): Allocate TYPE_CPLUS_SPECIFIC for
814 (read_struct_type): Ditto. Also, add comments about how we can
815 deduce TYPE_VPTR_FIELDNO from inheritance info and fieldname info.
816 * coffread.c (decode_base_type): Allocate TYPE_CPLUS_SPECIFIC for
818 (read_struct_type): Ditto.
819 * dwarfread.c (struct_type): Ditto.
821 * symtab.c (read_range_type): Don't set TYPE_MAIN_VARIANT.
822 (lookup_pointer_type): Don't use or set TYPE_MAIN_VARIANT.
823 (lookup_reference_type): Ditto.

832 * mipsread.c (parse_partial_symbols): patch to keep DEC C
833 compiler from making gdb bomb out. Thanks to Ed Santiago!
835 Thu Nov 14 19:27:30 1991 Fred Fish (fnf at cygnus.com)
837 * symfile.c: Add function compact_misc_function_vector() to
838 remove duplicate misc function vector entries. See comments
839 in source for why this is necessary/desirable.
841 * dwarfread.c: Add misc function type parameter to internal
842 record_misc_function(). Remove calls to init_misc_bunches()
843 and condense_misc_bunches(), these are now done in elfread.c.
845 * elfread.c: Add support for reading bfd canonical symbol tables
846 and generating misc function vector entries for global and
847 absolute symbols. Do calls to init_misc_bunches() and
848 condense_misc_bunches() where they will enclose all calls to
849 record_misc_function(), including those in dwarfread.c.
851 Thu Nov 14 17:02:11 1991 Roland H. Pesch (pesch at cygnus.com)
853 * doc/Makefile.in: new targets gdb.me, gdb.ms, gdb.mm
854 (roffable documentation).
855 * doc/gdb.texinfo: embedded hints (as comments) for better
856 texi2roff conversion.

872 Motorola 88000 port without tears, I mean without tdescs.
874 * m88k-tdep.c: Blow away all tdesc stuff.
875 Provide functions for all the frame-related macros in
876 tm-delta88.h. Adopt i960-style EXTRA_FRAME_INFO.
877 (examine_prologue, frame_find_saved_regs, skip_prologue): borrow
878 from i960-tdep.c and adapt to the function prologues on the 88k.
879 (read_next_frame_reg): Borrow from mips-tdep.c.
880 FIXME: frame_locals_address should go away.
882 * tm-delta88.h: Dump all the tdesc stuff.
883 Macros for all frame-related stuff call fns of same name.
884 Remove duplicated definitions. FP_REGNUM becomes same as
887 * xm-88k.h: Eliminate lots of library dependencies, now handled
888 in libiberty. Eliminate KDB nonsupport.
890 * doc/gdbint.texinfo: Add rudiments on frames. FIXME, add more.

894 Print locals address (FIXME, remove if same).
895 * blockframe.c: Comment changes, FIXME after.
896 * coffread.c: Even without TDESC, need to zap "@" symbols.
897 Don't register for wierd format names; change the names in BFD.
899 * alloca.c, language.c, tdesc.c: Lint.
900 * tdesc.c, tdesc-lib: FIXME: remove these.
902 Tue Nov 12 19:30:22 1991 John Gilmore (gnu at cygnus.com)
904 * Makefile.in: Add tdesc library support. Fixups to lint,

911 Allow setting breakpoints on C++ destructors.
912 * valops.c (destructor_name_p): Don't check TYPE_HAS_DESTRUCTOR,

914 * symtab.c (decode_line_1): For example (see above), here.
915 * buildsym.c, symtab.h: Remove TYPE_FLAGS_HAS{CON,DE}STRUCTOR
916 flags since they are no longer used.
918 Fixes to support C++ methods with functional parameters.
919 * c-exp.y (func_mod rule): Allow (and ignore) list of parameter
920 types in a function type.
921 * eval.c (parse_and_eval_type), value.h: New function,
922 parse_and_eval_type, is based on old code from check_stub_method.
923 But don't actually evaluate the cast, since that calls
924 value_cast(), whcih may fail. Just extract the type
925 from the parsed expression.
926 * values.c (check_stub_method): While looping through the
927 arguments, adjust depth *after* parameter has been handled.
928 Replace call and setup of parse_and_eval with new function

956 (and possibly arguments to) the program that generated a core
959 * elfread.c: Remove the register_addr() stub now that it is no
962 * procfs.c: Move misplaced #endif for ATTACH_DETACH. Add new
963 fetch_core_registers() function for core file support.

967 * dwarfread.c (dwarf_psymtab_to_symtab): Remove leftover call
968 to do_cleanups() which resulted from a previous change.
970 * elfread.c: Re-enable compilation of register_addr() stub
971 whenever it is not supplied by coredep.c
973 Sat Nov 9 00:40:32 1991 John Gilmore (gnu at cygnus.com)
975 Add tracking of object files (that contain symbols) to gdb.
976 This includes a "struct objfile" that owns symtabs and psymtabs
977 that were read in from that binary file.
979 * symfile.h: Add struct objfile. Add pointer to the objfile
980 into the struct sym_fns.
981 Replace global `symfile' and `symfile_mtime' with
982 `symfile_objfile'. Add global object_files chain.
984 * symfile.c: Move param.h above symtab.h.
985 (sort_misc_function_vector): Add.
986 (syms_from_objfile): Was syms_from_bfd.

1001 Pass objfile. Change callers.
1002 (fill_symbuf, SWAP_SYMBOL): Take bfd as arg.
1003 (read_dbx_symtab): Just wipe out new symbols, not all, on error.
1004 (end_psymtab): Blow away psymtab if empty.
1005 (process_symbol_pair): Swallow into read_ofile_symtab.
1006 (process_one_symbol): Use push_context and pop_context.
1007 (virtual_context): Delete #if 0'd obsolete stuff.
1009 * buildsym.c (end_symtab): Pass objfile.
1010 (dbx_lookup_type): Handle null typevector.
1011 (dbx_alloc_type): Check file number, not sym number, for -1.
1012 (find_symbol_in_list): Add for xcoffread.
1013 (start_symtab): Default typevector is empty. Keep reusing same
1015 (end_symtab): Take objfile argument and pass it to
1016 allocate_symtab. Don't make a symtab if no blocks or symbols.
1017 Handle empty typevector.
1018 (push_context): New function for context stack nesting.
1019 (read_type): Mark FIXME where we need to reintroduce type smashing.
1021 * buildsym.h (pop_context): Macro, paired with push_context.
1022 (subfile_stack): Move here from dbxread.c.
1024 * coffread.c (end_symtab, read_coff_symtab): Take and use objfile arg.
1025 (read_coff_symtab): Cleanup by freeing objfile, not all symtabs.
1027 * mipsread.c (read_mips_symtab, parse_partial_symbols, parse_fdr,
1028 new_psymtab, new_symtab): Take and use objfile arg.
1030 * dwarfread.c (scan_compilation_units, start_psymtab,
1031 process_dies, end_symtab, dwarf_build_psymtabs,
1032 read_lexical_block_scope, read_func_scope, read_file_scope): Take
1033 and use objfile argument.
1034 (psymtab_to_symtab_1, read_ofile_symtab): Don't take or use file
1035 descriptor. Use BFD internal functions instead.
1036 (end_symtab): Call global allocate_symtab.
1038 * elfread.c, target.c: Minor changes to accommodate objfiles.
1039 * symtab.h: partial_symbol_table has no symfile_name member now.
1040 (fn_fieldlists voffset): avoid non-int bitfield.
1041 (struct symtab): Add objfile * and objfile_chain * of symtabs.
1042 (struct partial_symtab): Add objfile * and objfile_chain * of
1043 psymtabs. Remove symfile_name.
1045 * symmisc.c: Lose free_all_symtabs, free_all_psymtabs.
1046 (printsyms_command): Rename from print_symtabs. Add selective
1047 listing if 2nd argument given. Print objfile info.
1048 (printpsyms_command): Rename from print_partial_symtabs. Ditto all.
1049 (printobjfiles_command): New; prints objfiles lists, and checks
1050 for consistency of symtab, psymtab, and objfile lists.
1052 * symfile.h, symfile.c, symtab.h: Lint
1054 Fri Nov 8 23:38:48 1991 John Gilmore (gnu at cygnus.com)
1056 * command.c: Include param.h.
1057 * defs.h (warning_setup, warning): Declare.
1058 * expprint.c (print_subexp, UNOP_MEMVAL case): Lint.
1059 * inflow.c (new_tty): Use USE_O_NOCTTY #define.
1060 * language.c, printcmd.c (print_scalar_formatted), signame.c,
1063 Thu Nov 7 18:26:15 1991 Steve Chamberlain (sac at rtl.cygnus.com)
1065 * Makefile.in: link with libiberty after libreadline, since
1066 readline might want something in libiberty.
1067 * m88k-xdep.c: Fixed the register offsets in the ptrace_user
1068 struct for BCS 88k machines.
1069 * xm-m88k.h: don't define USIZE if already defined.
1070 * configure.in: Added delta88 target.
1072 Thu Nov 7 04:51:19 1991 John Gilmore (gnu at cygnus.com)
1074 * am29k-pinsn.c, am29k-opcode.h: Fix decoding of mtacc, dmac, fmac.
1076 * tm-*.h: Remove READ_DBX_FORMAT, COFF_FORMAT, and
1077 READ_MIPS_FORMAT, which have been unused since BFD. Still
1078 remaining is COFF_NO_LONG_FILE_NAMES.
1079 * tm-sun3.h, tm-altos.h: Remove detritus accidentally left from
1080 function calling code moved to m68k-tdep.c.
1082 Wed Nov 6 17:21:59 1991 John Gilmore (gnu at cygnus.com)
1084 * coffread.c: Eliminate c_nsyms in favor of c_naux.
1085 Complain if no auxents on .bf and .ef FCN symbols, and assume
1086 lots of line numbers.
1087 (init_linenos, enter_linenos): Use a sentinel at the end of the
1088 read-in linenos, to make for a fast, safe loop-end test.
1090 Wed Nov 6 02:54:08 1991 Steve Chamberlain (sac at cygnus.com)
1092 * coffread.c (read_coff_symtab): coffread used to rely on the
1093 x_sym.x_misc.x_lnsz.x_lnno field giving the # of linnos in a
1094 function. Two of the formats I'm using (29k and 88k) don't seem to
1095 set it. Ths patch to fcn_last_line and (enter_linenos) is an
1096 attempt to use the actual size of the linno table in the file to set
1097 the number of linenos to process.
1099 Tue Nov 5 22:47:46 1991 Steve Chamberlain (sac at cygnus.com)
1101 * Makefile.in: put a - infront of the mv y.tab.c c-exp.tab.c and
1102 mv y.tab.c m2-exp.tab.c, so that if bison is used, and the files
1103 are created in place, so the mv fails, then the make continues.
1105 Tue Nov 5 16:47:47 1991 Per Bothner (bothner at cygnus.com)
1107 Add C++ as a separate language.
1108 * defs.h (enum language): Add language_cplus.
1109 * dwarfread.c (end_symtab): Support language_cplus.
1110 * c-exp.y: Add new struct language_defn cplus_language_defn.
1111 Don't set c to be the default language (see main.c).
1112 * c-exp.y (yylex): Only look for field of this if
1113 language is C++. (First difference from C!)
1114 * language.c: Add case branches for C++ (currently, all
1115 the same as C). Also, add c++ to "usage" note for "set lang".
1116 * valprint.c (typedef_print). Add case branches for C++.
1117 * main.c (main): New way to set initial language: Look at
1118 file extension of psymtab containing main(). (Same as we
1119 do for symtabs, but avoid loading the symtab yet.)
1120 * symtab.c: New routine find_main_psymtab(), used by main()
1121 to set initial language.
1122 * symfile.c (allocate_symtab): Move code for mapping file
1123 extensions-> languages to new deduce_language_from_filename().
1125 Fix a C++ problem when looking for methods in super-classes.
1126 There was confusion between base and derived types.
1127 * valops.c (value_fn_field): Change function interface.
1128 * values.c: Use new value_fn_field interface.
1130 Mon Nov 4 10:49:33 1991 Per Bothner (bothner at cygnus.com)
1132 * infrun.c: Fixed typo in comment.
1133 * utils.c: All the v*fprintf emulation is now in libiberty,
1134 so we can get rid of some junk.
1135 * xm-sun3os4.h, xm-sun4os4.h, xconfig/decstation, xconfig/i386sco,
1136 xconfig/sun3os4, xconfig/sun4os4: Don`t need HAVE_STRSTR any more.
1137 * m68k-pinsn.c (print_insn_arg): Support BB/BW/BL
1138 type operands, as used by branch instructions.
1139 * gmalloc.c: Fix prototype of memcpy.
1140 * elfread.c: Comment out register_addr, since it conflicts
1141 with the one in coredep.c.
1142 * buildsym.h: Remove extern declarations of two functions
1143 that are really static in buildsym.c.
1144 * tm-mips.h: Add symbolic names for more registers.
1145 * mips-xdep.c (store_inferior_registers): Use new register names.
1146 * xm-mips.h: Simplify REGISTER_U_ADDR, since it is now
1147 only used for core files, not ptrace. Therefore,
1148 the KERNEL_U_ADDR hack is no longer needed.
1149 The mapping to ptrace number is now in in mips-xdep.c.
1150 * mips-xdep.c: Define REGISTER_PTRACE_ADDR (using the
1151 mapping from the old REGISTER_U_ADDR), and use it
1152 in {fetch,store}_inferior_registers.
1153 * mipsread.c: Rename #include ecoff.h to new name coff-mips.h.
1154 * mips-tdep.c (mips_push_dummy_frame, mips_pop_frame):
1155 Save/restore FP regs correctly (?).
1156 * dbxread.c: Remove duplicate define_symbol and type_synonym_name
1157 (these had been previously moved to buildsym.c).
1158 Hence, define_symbol becomes extern instead of static.
1159 * buildsym.c (read_struct_type): Comment out bogus handling
1160 of C++ operator methods. Minor hacking of reading of class
1161 contexts. Make define_symbol non-static, so dbxread.c can call it.
1163 Fri Nov 1 11:05:47 1991 John Gilmore (gnu at cygnus.com)
1165 * mipsread.c (read_mips_symtab, read_the_mips_symtab): Use real
1166 filename with error messages.
1167 * stack.c (frame_select_command): Rename to select_frame_command
1168 to avoid "fr" and "fra" having nonunique completions.
1169 * symfile.c (sort_symtab_syms): Ignore sort of zero symtab *.
1170 (symfile_init): Print file format name when unable to handle it.
1171 (free_named_symtabs): Use BLOCKVECTOR rather than obsolete BLOCKLIST.
1172 * symmisc.c (free_symtab): Only free linetable if nonzero.
1173 * symtab.h: Remove obsolete BLOCKLIST macros.
1175 Thu Oct 31 18:12:43 1991 Stu Grossman (grossman at cygnus.com)
1177 * infrun.c (wait_for_inferior): another stepi/nexti fix. Ensure
1178 that stop_step is 1 at bottom of main loop. I don't know why this
1179 needs to be done, but it helps me sleep better at night.
1181 Sun Oct 27 18:18:39 1991 Stu Grossman (grossman at cygnus.com)
1183 * main.c (initialize_history): Read history after reading all
1186 Sun Oct 27 14:09:25 1991 John Gilmore (gnu at cygnus.com)
1188 * buildsym.c: Break out initial malloc sizes.
1189 (record_line): Record directly in a subfile. Alloc on demand.
1190 (compare_line_numbers): Add from xcoffread.c.
1191 (end_symtab): New params say whether to sort pendings and
1192 linetable. Patch block stabs if defined. Shrink linetable before
1193 allocating the symtab.
1194 * buildsym.h: Delete line_vector* and prev_line_number. Add
1195 global_stabs and file_stabs for xcoffread.
1196 * dbxread.c (start_subfile): Move to buildsym. Change above calls.
1197 * symtab.h: LINETABLE(symtab) can now be null. Zap LINELIST.
1198 * symmisc.c, symtab.c: Cope with null LINETABLEs.
1200 * blockframe.c: Pass fromleaf to INIT_EXTRA_FRAME_INFO.
1201 * tm-29k.h, tm-88k.h, tm-i960.h, tm-irix3.h, tm-mips.h, tm-pyr.h,
1202 tm-sparc.h: Accept fromleaf parameter.
1203 * c-exp.y (yyerror): Pass error message if given.
1204 * configure.in: Add rs6000 host and target.
1205 * inflow.c (new_tty): O_NOCTTY kludge for RS/6000.
1206 * symfile.h (entry_point): Add.
1208 Sat Oct 26 00:16:32 1991 John Gilmore (gnu at cygus.com)
1210 * buildsym.c: New file. Breaks out symbol-table-building routines
1211 from dbxread.c, so they can be shared with xcoffread.c.
1212 * buildsym.h: New file. Declarations for buildsym.c users.
1213 * dbxread.c: Remove large chunks into buildsym.c.
1214 * Makefile.in: Add buildsym.c and buildsym.h.
1216 * symfile.c (syms_from_bfd): New routine.
1217 (add_symbol_file): Call it to do the real work.
1218 (syms_from_bfd): Initialize entry_point before calling symfile_init.
1219 * symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
1220 Avoid declaring or setting entry_point (symfile.h & symfile.c cope).
1222 Fri Oct 25 10:58:16 1991 Mark Eichin (eichin at cygnus.com)
1224 * cplus-dem.c (cplus-demangle): added support for templates, static
1225 data, and the new (correct) mangling for destructors.
1227 * dwarfread.c: (dwarfwarn): created a varargs version of
1228 dwarfwarn, for non __STDC__ compilers.
1230 * c-exp.y: (yylex): added match for "template" token.
1231 (typebase): added TEMPLATE name '<' type '>' clause, for explicit
1232 specification of template types.
1234 * symtab.c: (lookup_template_type): new function for finding
1235 templates in symbol table.
1236 (type_name_no_tag): changed to explicitly check for s/u/e at the
1237 beginning of the symbol - if it is a template, none of these will
1238 be there (but the name will still contain spaces.)
1240 Fri Oct 25 18:59:32 1991 Per Bothner (bothner at cygnus.com)
1242 Various fixes to improve g++ debugging.
1243 * symtab.h: Add is_const and is_volatile flags for each method.
1244 These are bit fields - take their space from voffset,
1245 which shrinks to 30 bits. Since voffset is now a bitfield,
1246 make it unsigned for portability. This changes its interpretation
1247 slightly: Static methods now have voffset 1 instead of -1,
1248 and virtual offsets start at 2, not 1.
1249 * symtab.c: Renamed gdb_mangle_typename to gdb_mangle_name,
1250 since it now returns an entire magled method name, not just
1251 the type part. This avoids some duplication.
1252 It also allows us to correctly mangle const and volatile
1253 methods (using the new is_const and is_volatile bit fields
1255 * valprint.c (type_print_base), values.c (check_stub_method):
1256 Simplify by using new gdb_mangle_name.
1257 * values.c (value_headof): Fix to correctly handle single
1258 inheritance (actually two fixes, either of which suffices).
1259 * dbxread.c (read_struct_type): Handle const and volatile
1261 * dbxread.c (read_struct_type): Yet one more place where
1262 we must handle '\\' continuations.
1263 * valprint.c (vtbl_ptr_name): Add final '\0'.
1265 Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com)
1267 * tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of
1268 short return values for sparc and 68k. Patch from Paul Eggert.
1270 * coffread.c, coredep.c, i386-xdep.c: install patches for
1271 SysV/386 3.2 from Mauro DePalma.
1273 Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
1275 * core.c (core_file_info), exec.c (exec_file_info): Print file
1276 type. Use printf_filtered.
1278 * valops.c (value_fetch_lazy): Avoid 0-length fetches.
1280 Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
1282 * dwarfread.c: Add casts to remove compiler warnings.
1284 * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
1285 tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
1286 tm-sun3.h: Remove locally duplicated code for calling functions
1287 in the inferior. The only differences were in the specific trap
1288 vectors used and whether or not an fpu was present. These are
1289 now handled by appropriate definitions of BPT_VECTOR and
1290 HAVE_68881 respectively. Other minor obvious cleanups.
1292 * valops.c: Correct a minor misspelling.
1294 * utils.c: Remove local BSD/USG hacks that are now in libiberty.
1296 * dwarfread.c: Remove prototype for dwarfwarn. Does not work
1299 Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
1301 * stack.c (frame_command): Always print. Use new
1302 frame_select_command to select a frame without printing.
1304 * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
1306 Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
1308 * dwarfread.c: New file for DWARF debugging format support.
1310 * elfread.c: New file for ELF object file format support.
1312 * procfs.c: New file for SVR4 /proc (process file system) support.
1314 * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
1317 * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
1319 * xm-m68k.h: New file for host machines with m68k cpu.
1321 * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
1322 Add elfread.o and dwarfread.o to OBS.
1324 * symfile.h: Add "elf" to list of supported formats in comment.
1326 * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
1327 types to gdb, builtin_type_long_double, builtin_type_complex, and
1328 builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
1329 TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
1330 TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
1331 TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
1332 types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
1334 * infrun.c: When using SVR4 /proc interface instead of ptrace(),
1335 call proc_set_exec_trap() to setup child to stop at first instruction.
1337 * inftarg.c: When using SVR4 /proc interface, call proc_wait()
1340 * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
1341 supply_fpregset(), and fill_fpregset(), which are machine
1342 dependent support routines for SVR4 /proc interface.
1344 * utils.c: Add warning_setup() and warning(). Warning() behaves
1345 the same as error() except that it returns normally rather than
1346 jumping back to command level. Modules that don't want to call
1347 warning() for some reason, but want to produce their own warnings,
1348 can call warning_setup() to ensure compatibility with the way
1349 warning() and error() deal with the terminal.
1351 * symtab.c: Make internal errors produce more useful messages.
1353 * tm-68k.h: Move code that is duplicated in almost every single
1354 m68k based machine's configuration files to this common file.
1355 Duplications in the configuration files still need to be removed
1358 * infrun.c (child_create_inferior): System V versions must call
1359 setpgrp() with no arguments, to comply with prototyping typically
1362 * munch: Add support for SVR4 style nm output.
1364 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
1365 file specific fields from the partial symbol table structure and
1366 replace them with a pointer to private data for each different
1367 flavor of object file reader to initialize appropriately.
1369 Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
1371 * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
1374 * mipsread.c (fixup_undef_type): New function. If a struct /
1375 union / enum is defined in a header file but nowhere else used,
1376 (by typedefing, pointer referencing or declaration) the mipsread code
1377 builds the complete tree for the structure but leaves its code as
1378 TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
1379 Guess its type based on the details of the members.
1381 Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
1383 * infrun.c (wait_for_inferior): Check return value from
1386 Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
1388 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
1389 by my last edit to this routine.
1391 Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
1393 * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
1394 FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
1395 the values before putting them into the dummy code. (From Peter
1398 Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
1400 * configure.in: added ebmon target.
1402 Wed Oct 16 22:49:58 1991 John Gilmore (gnu at cygnus.com)
1406 * Makefile.in: Roll VERSION to 4.2.
1407 * README, TODO, WHATS.NEW: Update.
1409 * core.c (core_open): Improve error message for bad file.
1410 Pass .reg virtual memory address to fetch_core_registers to help
1411 it find the registers in the core-file header.
1412 * coredep.c (fetch_core_registers): Take new argument, use it,
1413 and pass it to register_addr to locate the block of registers.
1414 * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
1416 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
1417 Sequent N_FN_SEQ like everybody else's N_FN.
1419 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
1420 * tm-i386v.h: #endif guck.
1421 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
1422 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
1423 * xconfig/tahoe: Add REGEX, which seems to be missing.
1425 * coredep.c: Add <sys/types.h> for SCOnix.
1426 * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file.
1427 * printcmd.c (print_formatted): Flush output before disassembly.
1429 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1431 * doc/refcard.tex (sec "Working Files"): consistent metavars and
1432 other improvements, due to comments by François Pinard
1433 (pinard@iro.umontreal.ca)
1435 * doc/gdb.texinfo (appendix "Installing GDB"): changes in
1436 configure, and improvenets related to Pinard's refcard comments
1438 Tue Oct 15 08:45:12 1991 John Gilmore (gnu at cygnus.com)
1440 Changes from Fred Fish:
1441 * tm-68k.h (FPI_REGNUM): Add.
1442 * infrun.c (child_create_inferior): flush stdout and stderr
1444 * configure.in: Handle amigados, amix hosts and targets.
1445 * inflow.c: Handle TIOCGLTC_BROKEN for Amiga.
1447 From Andreas Schwab:
1448 * values.c (show_convenience): Use printf_filtered.
1449 * main.c (define_command): Check result of lookup_command for
1451 (echo_command): Use printf_filtered, and force output out.
1453 * dbxread.c (read_enum_type): Avoid Modula-2 kludge that breaks C
1455 * i387-tdep.c (double_to_i387): Fix typo for double_to_ieee_extended.
1456 * utils.c (_initialize_utils): If !ISATTY, don't paginate.
1457 * configure.in, tconfig/decstation, xconfig/decstation: Rename
1458 dec3100 to decstation.
1460 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)
1462 * doc/gdb.texinfo: Catch up to changes recorded here in ChangeLog
1463 (nodes Continuing and Stepping; Memory; Targets) clarifications
1466 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
1468 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move
1469 REGISTER_U_ADDR to corresponding xm- file. Sugg. by Peter Schauer.
1471 * symmisc.c (print_partial_symtabs): Add printpsyms debug cmd.
1473 * m68k-tdep.c (m68k_push_dummy_frame, m68k_pop_frame): Add
1474 generic routines for calling inferior functions.
1476 * blockframe.c (inside_main_scope, inside_entry_scope): New.
1478 * copying.awk: Filter formfeeds out of copying & warrantee.
1479 Make them available as `show copying' and `show warrantee' also.
1480 * main.c (print_gnu_advertisement): Advt `show' commands.
1482 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)
1484 * mach386-xdep.c: Even when cross-compiling, leave in the
1485 core-file reading code.
1486 * core.c (get_core_registers): Avoid coredump if no .reg section.
1488 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
1490 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
1491 This avoids coredumps under `set print object on' in value_headof
1492 (called erroneously by value_from_vtable_info) for `p &struct'
1493 or `p *struct'. From Peter Schauer.
1495 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
1497 * Makefile.in: Roll version to 4.1.2.
1498 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
1499 size from BFD (but, FIXME, we don't yet read external nlists's and
1500 convert them to internal nlists's before handling them -- we still
1501 assume they have the same size and alignment.) Use SET_NAMESTRING
1503 * exec.c (exec_file_command): Move dead coff-encapsulation code
1505 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.
1507 Fri Oct 4 22:30:06 1991 John Gilmore (gnu at cygnus.com)
1509 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
1510 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
1512 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
1514 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
1515 * mips-xdep.c (store_inferior_registers): Don't try to
1516 write the (pseudo) FP.
1517 * mipsread.c (parse_partial_symbols): Improved algorithm for
1518 setting pst->texthigh.
1520 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
1522 * doc/Makefile: make TEXINPUTS include . everywhere
1524 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
1526 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
1527 vestiges of typevectors, which were for symsegs and are no longer
1528 used. (From a question by Eliot Dresselhaus
1529 <dresselh@RFT30.nas.nasa.gov>).
1531 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
1533 * dbxread.c, coffread.c: static-ize functions that were
1534 gratuitiously external. (From Fred Fish.)
1536 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
1538 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
1539 until it is large enough.
1541 * dbxread.c (read_type): Handle error case slightly better.
1542 Make complaint message not C++-specific.
1544 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
1546 * infrun.c (wait_for_inferior): Fix step/next so that you only
1547 stop at the beginning of a new line. This fixes various problems
1548 with for loops, nested if-else's and switch statements.
1550 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
1552 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
1553 between symtabs and psymtabs become ordinary error()s.
1555 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
1556 properly, making "end pc" correct in shared lib psymtabs.
1557 (From Guy Harris <guy@auspex.com>.)
1559 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
1561 * dbxread.c: Enable, but soften, const_vol_complaint.
1562 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
1563 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
1564 should be file-scope, not global.
1565 (read_struct_type): Remove ancient multiple-inheritance warning.
1566 (read_range_type): Check base type, complain & patch if undefined.
1567 * stack.c (frame_info): Demangle the function name in `info stack'.
1568 (From Peter Schauer)
1570 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
1572 * eval.c (evaluate_subexp_for_address): Don't use
1573 TYPE_POINTER_TYPE directly (it might be zero if this type has
1574 never had a pointer created before); use lookup_pointer_type.
1575 * symtab.c (lookup_method_type): Arguments were swapped in all
1576 callers, so fix it here. I'm amazed this worked at all!
1578 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
1580 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
1581 "bss" rather than "data" symbols, but which still conflict.
1584 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
1585 * core.c (core_files_info): Shorten output.
1586 * exec.c (exec_files_info): Ditto.
1587 (build_section_table): Ignore zero-length sections.
1588 * language.c, printcmd.c: Lint.
1589 * language.h (get_frame_language): Declare.
1590 * saber.suppress: update.
1591 * stack.c (find_relative_frame): Remove complex code that was
1592 #if 0'd, stick with simple code. Lint.
1593 * saber.suppress: Update a bit.
1594 * symfile.c (add_symbol_file_command): Add "?" to question.
1595 * utils.c (parse_escape): Avoid \a due to bdead compilers.
1596 * value.h: Declare typedef_print.
1598 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
1601 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
1602 (Reported by Mark Peek <mark@imagen.com>.)
1604 * solib.c (solib_map_sections): Relocate all sections, even
1605 though only the text section's size is tracked. Mark ld_text
1606 for eventual elimination as we generalize to N sections.
1608 * infrun.c (wait_for_inferior): Don't check if the PC is in a
1609 call_dummy if we were stopped by a random signal that is being
1610 passed to the program. This produced wierd results when calling
1611 functions in the inferior and signals (e.g. SIGALRM) were in use.
1613 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
1615 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
1616 Bugfix from Paul Eggert <eggert@twinsun.com>.
1617 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
1618 * valprint.c (print_floating): Print 9 digits for IEEE floats.
1621 Mon Sep 23 15:50:07 1991 John Gilmore (gnu at cygnus.com)

1627 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
1631 * Makefile.in (VERSION): Set to 4.1.
1632 * language.c (set_language_command): Print useful help message,
1633 and restore the language string after giving help.
1634 * valprint.c (typedef_print): Print typedef in C or M2.
1635 * symtab.c (list_symbols): Use it.
1636 * main.c (main): Avoid any output before (gdb) prompt when -q.
1637 * language.c (set_language_command): Handle errors by restoring
1638 the language string to its current state (fix from A. Beers).
1639 * doc/gdbint.texinfo: Roll in information from README. Rearrange
1640 "how to install" and "how to print the doc" stuff so it drops
1642 * configure.in: Rename rtpc CPU to romp to match config.sub.
1643 * README, WHATS.NEW, TODO: Update for gdb-4.1.
1645 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
1647 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
1648 autoloading shared libs, copyright etc on GDB startup, clean up $_
1649 and $__ index refs, set/show listsize and related updates to list
1650 cmd. New host/target configs.
1652 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
1654 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
1655 from main Makefile.in version definition
1656 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
1658 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
1660 * doc/gdb.texinfo: merge new language-switching and lang-specific
1663 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
1665 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
1666 compilers (which may lack stddef.h).
1668 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
1670 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
1671 N_WARNING are the same except for the N_EXT bit, so just use their
1672 values alone, rather than OR-ing them with N_EXT.
1674 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
1676 * mipsread.c (parse_lines): Deal with negative extended line
1679 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
1680 global symbol conflicts.
1682 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
1684 * .gdbinit: Move 'set complaints' to top, so it runs even in
1685 case we aren't debugging GDB.
1686 * language.c (_initialize_language): Fix type check and range
1687 check documentation strings.
1688 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
1689 language.c can use it. (Though language.c should really not be
1690 handling warnings/errors the way it does, FIXME.)
1691 * symtab.c (lookup_primitive_type): const lint.
1693 Bugfix from Peter Schauer:
1694 * source.c (lines_to_list): Make signed, to avoid comparison
1695 going unsigned and complaining that -3 is too high for 21 lines.
1696 * stack.c (lines_to_list): Ditto.
1698 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
1700 * Makefile.in (HFILES): Add minimon.h.
1701 (VERSION): Roll version number to 4.0.95.
1702 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
1703 New rules for building distributions. Normal distribution
1704 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
1705 one level up from here; it calls make-proto-gdb.dir to build a
1706 directory `proto-gdb' which is an image of the release. The old
1707 `gdb.tar.Z' rule still works too.
1708 * config.sub, configure: Roll in latest from ..
1710 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
1712 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
1713 new-target, and new-config chapters; fix minor typos; come closer
1714 to usual GNU markup conventions for @file @samp @code @var.
1716 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
1718 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
1719 * mipsread.c (parse_partial_symbols): Enter the name of all
1720 structs/unions... into the psymtab so we can access them if the
1721 symtab is not read in.
1722 * mips-tdep.c: Remove some unneeded #includes.
1723 * xconfig/dec3100: Add HAVE_STRSTR.
1725 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
1727 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
1728 * c-exp.y, m2-exp.y: Lint.
1729 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
1730 * valprint.c (val_print_fields): Check for stub type.
1731 * mipsread.c (_initialize_mipsread): Avoid using
1732 builtin_type_void at initialize time.
1733 (mipscoff_symfile_read): use it now.
1735 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
1737 Merge multiple-language support, and partial Modula-2 support,
1738 from Andrew Beers <beers@cs.buffalo.edu>.
1740 * i387-tdep.c: New file, consolidates most 80387 support,
1741 and eliminates host dependency on double<->extended conversions.
1742 * i386-xdep.c, symm-xdep.c: Remove most 387 support.
1743 * xconfig/i386{sco,v,v-g,v32,v32-g}: Now need i387-tdep.o.
1745 * symfile.c (allocate_symtab): New fn, consolidates the work
1746 of allocating and initializing a new struct symtab. Set the
1747 language of the symtab based on its filename extension.
1748 * symfile.h: Declare it.
1749 * mipsread.c (new_symtab): Use it. Minor formatting changes.
1750 * dbxread.c (end_symtab): Use it.
1752 * mipsread.c (parse_symbol, case stParam and stProc): Add #if 0'd
1753 code for saving types of parameters with each function definition.
1754 * dbxread.c (define_symbol, function and parameter cases): Ditto.
1755 (read_dbx_symtab, case N_DEFD): Ignore.
1756 (read_enum_type): Recognize FALSE/TRUE enum as Modula-2 BOOLEAN.
1757 (read_range_type): Rename MAX_OF_TYPE to MAX_OF_C_TYPE, etc.
1758 #if 0 out its uses, though, since they set a dead value.
1759 * coffread.c (end_symtab): Use allocate_symtab.
1760 (process_coff_symbol): #if 0'd for functions and params as above.
1761 (read_enum_type): Recognize Modula-2 BOOLEAN.
1762 * symtab.c (add_param_to_type): #if 0'd function to add a
1763 parameter type to a function type's field list.
1765 * defs.h (local_hex_format, local_hex_string, *_custom): Add.
1766 * i386-xdep.c, pyr-tdep.c, pyr-xdep.c, remote-vx.c, solib.c,
1767 source.c, symfile.c, dbxread.c, breakpoint.c, core.c, exec.c,
1768 i387-tdep.c, infcmd.c, mips-tdep.c, stack.c, printcmd.c: Output
1769 hex with local_hex_string for Modula-2 support.
1771 * breakpoint.c (breakpoint_cond_eval): Use new value_true to test
1772 breakpoint condition language-independently.
1774 * parse.c: New file with the common code remains of expread.y.
1775 * parser-defs.h: New file with common declarations from expread.y.
1776 * c-exp.y: New file with the C parser from expread.y, and other

1805 * stack.c (frame_info): Print language of stack frame.
1806 (select_frame): Also select language, if in auto-mode.
1807 (get_frame_language): New subroutine.

1834 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
1836 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
1837 entries are enclosed herein. Not all of these changes
1838 have been merged into the master GDB sources -- check the
1839 ChangeLog above here for the merge log.
1841 Mon Jun 3 17:05:45 EDT 1991
1843 m2-exp.y Created. Tested outside of GDB for a few days. Proper
1844 operators were added, C specific operators and tokens
1845 removed. yylex() revamped to some extent. Still things
1846 missing from the grammar, such as sets.
1847 Tested for two weeks in GDB v3.5.
1849 Tue Jun 11 17:23:48 EDT 1991
1851 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
1852 so they are built-in. Sort of a hack.
1854 Fri Jun 14 12:53:51 EDT 1991
1856 m2-exp.y Added range checking for numeric constants. Any numeric
1857 constant is assumed to be of builtin type INTEGER unless:
1858 (1) it is octal or hexadecimal, in which case it is a
1859 CARDINAL; (2) it is too big to fit into an INTEGER, in
1860 which case it is a CARDINAL.
1861 eval.c Added simple range checking for +, -, and * on integers.
1862 Doesn't work very well for *, since 6 * 1,000,000,000 =
1863 1,705,032,704, which fails the simple test of result >=
1864 first_operand, no matter in what order the operands are.
1866 Tue Jun 18 14:11:30 EDT 1991
1868 Broke the parser into parts, one containing the C grammar and the other
1869 containing code to be shared by all of the grammars.
1871 The following files no longer exist:
1876 The following files were added:
1878 c-exp.y (The C grammar)
1879 m2-exp.y (The Modula-2 grammar)
1880 parser-code.c (Code that is shared by the above grammar)
1884 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
1885 now necessary to use the Bison compiler compiler, since it
1886 will generate function/variable prefixes other than yy.
1888 Tue Jun 18 16:47:49 EDT 1991
1890 symtab.[ch] Added the external variable working_lang, than holds the
1891 value of the current working language.
1892 Added the ennumerated type language_mode, with the values
1893 language_auto and language_manual, the former meaning that
1894 GDB sets working_lang as needed, and the latter meaning
1895 that the value of working_lang is totally under user
1897 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
1898 REAL, BOOLEAN and CHAR. Also added the type codes
1899 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1900 utils.c Added set_language_command and show_language_command to
1901 implement the GDB support commands "set language" and
1903 expression.h A number of identifiers were added to the type exp_opcode
1904 to facilitate Modula-2 builtin functions, integer
1905 division, and array indexing.
1907 Wed Jun 19 13:25:58 EDT 1991
1909 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
1910 if the language specified by working_lang requires the use
1911 of strict typing of expressions. Eventually, even this
1912 will be able to be changed by the user.
1913 Added the macro RANGE_CHECK, which evaluates to non-zero
1914 if the language specified by working_lang requires the
1915 checking of a value against the domain of its type.
1916 Eventually, even this will be able to be changed by the
1918 language.[ch] Predicates involving types (simple_type, ordered_type,
1919 same_type, integral_type, numeric_type, character_type,
1920 boolean_type, float_type) are added. These predicates are
1921 based on the current value of working_lang, and are handy
1924 Wed Jun 19 15:39:34 EDT 1991
1926 eval.c Added the function type_array_rank which computes the rank
1928 valarith.c Added the funtion value_bool, which when given a integer
1929 value.h value (ie. struct value *) as an argument, it returns a
1930 boolean value (ie. struct value *) true if that integer
1931 is non-zero, and a boolean value false otherwise.
1932 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
1933 will print out properly.
1935 Wed Jun 19 16:36:34 EDT 1991
1937 valops.c Added the function value_capitalize, which returns it
1938 value.h argument capitalized if its argument is a lowercase
1939 letter, or the argument unchanged if its argument is not a
1941 valarith.c Added the function range_check_p, which returns non-zero
1942 value.h if its value argument is between the integral bounds upper
1944 Added the function range_check_enum_p, which makes sure
1945 that its value argument is a valid member of the domain of
1947 Added the function range_check_range_p, which makes sure
1948 its value argument lies between the upper and lower bounds
1949 of its type argument, which must be a ranged type.
1950 Added the function check_array_index, which range and type
1951 checks an index of an array.
1952 Added the function value_multi_subscript, which computes
1953 array[idx1,idx2...idxN], given a value array and an array
1954 of values representing indicies.
1955 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
1956 unpack_long to work with TYPE_CODE_BOOL and
1959 Wed Jun 19 18:04:08 EDT 1991
1961 symtab.c Stored pervasive types in a structure and make
1962 lookup_pervasive_type() a lookup function that was based
1963 on working_lang. If lookup_pervasive_type() returned
1964 non-zero, then that value was returned (a fix, since
1965 before it simply wouldn't return the pervasive type.)
1966 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
1967 non-zero if the language specified by working_lang means
1968 "conversion" when it says "cast".
1969 valops.c Added the function value_real_cast(), which performs a
1970 value.h *cast*, not a *conversion*, which is what value_cast()
1971 does when it can. In particular,
1972 value_cast(<float_type>,4) = 4.0, while
1973 value_real_cast(<float_type>,4) = some mess.
1974 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
1975 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
1976 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
1977 and MIN on integral types. *NOTE*: These are currently
1978 hardcoded to work only if there are 8 bits per storage
1980 eval.c Made logical functions call value_bool to return a
1981 properly typed boolean value, based on working_lang.
1983 Thu Jun 20 11:55:27 EDT 1991
1985 valprint.c Types now print out in a Modula-2 fashion. This works for
1986 the cases when the type is printed out step-by-step, that
1987 is, it doesn't work when the name of a structured type
1988 (which includes the keyword "struct", etc.) is simply
1990 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
1991 since type specifications in C and Modula-2 are very
1992 different. The C printing of a type is very recursive,
1993 whereas in Modula-2 it is generally very simple. C has
1994 type prefixes and suffixes, which have no real analogue in
1995 Modula-2. Maybe type_print() should call a language
1996 specific type printer. This is also advantageous if we
1997 compile GDB to exclude some of the languages. We'll just
1998 leave those functions out.
2000 Thu Jun 20 16:57:10 EDT 1991
2002 dbxread.c When reading the complete symbol table in (via
2003 psymtab_to_symtab()), the number and types of function
2004 arguments are added to a function type. define_symbol()
2005 calls add_param_to_type() to accomplish this.
2006 Assumption: when we come across a function definition
2007 (N_FUN symbol with an 'f' or 'F' in the name), its
2008 arguments will appear before another function definition.
2009 When a function is found, a pointer to its type is placed
2010 in the global in_function_type. Changes that
2011 add_param_to_type() makes are to this global.
2012 valprint.c The type of a function now includes (for Modula-2) the
2013 types of its parameters.
2014 eval.c Type checking and a check for the proper number of
2015 arguments is now done for function calls. Not sure of the
2016 impact this has on C++ member function yet.
2018 Thu Jun 20 19:58:48 EDT 1991
2020 valprint.c Rewrote the type printer. Broke it into two language
2021 specific parts, adding the functions type_print_m2() and
2023 An unfortunate consequence is this: if you debugging a C
2024 program in Modula-2 mode (why?), info types does not work
2025 well with regular expressions, since the types are printed
2026 out in Modula-2 terminology, but stored in C terminology.
2027 language.[ch] Added the functions new_type_last(), type_keyword(), and
2028 type_sep() to aid in the printing of typedefs.
2029 symtab.c Made the printing of typedefs as language independent as
2030 possible through calls to new_type_last(), type_keyword(),
2033 Fri Jun 21 11:50:26 EDT 1991
2035 dbxread.c Check all incoming ennumerated types. If it looks like
2036 Modula-2's BOOLEAN type, then change the type_code of the
2037 type to TYPE_CODE_BOOL so we can process it as a boolean
2039 valprint.c Replaced some of the 0x%x with calls to sprintf and
2040 hexformat() in val_print().
2041 language.[ch] Added the function hex_to_string(), which converts its
2042 integral argument to a hexadecimal number (format is
2043 language based) and returns the result as a string.
2045 Mon Jun 24 12:25:07 EDT 1991
2047 valprint.c Some functions call type_print_1() directly, instead of
2048 value.h using type_print(), so they can specify where (column) to
2049 print things. Since type_print() takes care of language
2050 dependence, that needs to be called first. Added a
2051 parameter depth to type_print() (so it is now like
2052 type_print_1). Changed type_print to type_print_at, and
2053 made type_print a macro that passes a depth argument of
2055 symmisc.c Changed all calls to type_print_1 to calls to
2057 Makefile.dist Made it possible to build GDB for a specific set of
2058 depend languages. Do this by passing a definition for the macro
2059 LANGS to make. LANGS should be a string containing a
2060 space-separated list of language names (ie. LANGS="c m2").
2061 The default is to build all languages. Note that grammar
2062 files must follow the naming convention of <lang>-exp.y.
2063 gdb.lang This holds the current value of the LANGS macro. It is
2064 examined every time make is called, and is updated if
2066 eval.c Added #ifdef _LANG_<lang> to these files.
2067 expread.c Still need to add them to dbxread.c and coffread.c.
2075 Mon Jun 24 16:33:11 EDT 1991
2077 language.[ch] Added the functions hexformat_pre() and
2078 hex_to_string_pre(), which take a prefix argument to
2079 include in the format string. Thus, hexformat_pre("08") will
2080 return "0x08x" (if the working language is language_c).
2081 Made hexformat() and hex_to_string() calls to the above
2082 with "" as the prefix argument.
2084 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
2085 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
2086 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
2087 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
2088 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
2089 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
2090 valprint.c, vax-pinsn.c
2092 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
2093 calls to hexformat() and hex_to_string(). Format strings without
2094 the leading "0x" were ignored.
2096 depend Updated to take the above into account.
2099 Tue Jun 25 15:27:18 EDT 1991
2101 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
2102 and type_check_t to keep track of the current state of
2103 range and type checking.
2104 main.c Added the variables range_mode, range_check, type_mode,
2105 and type_check to record the current state of range and
2106 type checking. Added initialization code to main().
2107 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
2108 the above variables.
2111 Tue Jun 25 17:57:08 EDT 1991
2113 dbxread.c process_one_symbol() updates the variable (enum language)
2114 source_lang based on the extension of the filename
2115 contained in the N_SO sybmol that started this symtab.
2116 When end_symtab() is called, the value of source_lang is
2117 put into the language field.
2118 stack.c select_frame() sets working_lang (and possibly type_check
2119 and range_check) to the language field of the symtab
2120 associated with the frame that is selected if working_mode
2121 is language_auto. If working_mode is language_manual, a
2122 warning is printed and working_lang is not set.
2123 language.c Added the function set_type_range(), which sets the value of
2124 type_check and range_check (if their modes call for
2125 automatic setting) based on the current value of
2126 working_lang. A non-zero argument will cause the current
2127 settings to be output.
2130 Wed Jun 26 14:51:40 EDT 1991
2132 eval.c Added range checks on assignment.
2133 m2-exp.y Added the grammar for sets to the language. Currently,
2134 these do not do anything except print an error message.
2136 Wed Jun 26 17:01:04 EDT 1991
2138 m2-exp.y Added the ability for parse_number() to parse negative
2139 numbers. A global flag is set upon encountering a unary
2140 minus. This was done to make, for example, 1 parse as a
2141 CARDINAL, and not as an integer, per Wirth's examples in
2142 Programming in Modula-2 ed.4.
2143 valprint.c Added support for "set radix 2" by then setting
2144 output_format to 't'.
2145 eval.c Implemented range checking on subrange types. Added calls
2146 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
2147 Implemented MIN and MAX for ennumerated types. The
2148 minimum value of an ennumerated type is defined by Wirth
2149 as the first identifier, and the maximum as the last.
2150 m2-exp.y Made octal numbers ending with "B" be characters and those
2151 ending with "C" be numbers, per Wirth's book. (p. 34)
2153 Thu Jun 27 14:11:52 EDT 1991
2155 stack.c select_frame() now only sets working_lang, it does not
2156 notify the user. If working_mode is language_manual, then
2157 a warning is issued once.
2158 main.c At the end of each call to execute_command(), working_lang
2159 is checked against the local static (enum language)
2160 current. If they differ and working_mode is
2161 language_auto, the new settings of language, type and
2162 range checking are printed out.
2163 stack.c Modified frame_info() to include the language of the
2164 current frame in the output of "info frame".
2165 language.[ch] Added the function language_str() which returns the name
2166 of the current language.
2168 Fri Jun 28 15:33:14 EDT 1991
2170 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
2171 the language. INCL and DECL currently cause an error,
2172 since sets are not implemented yet. INC and DEC are
2173 implemented as PREINCREMENT/PREDECREMENT with one
2174 argument, and as ASSIGN_MODIFY with two arguments.
2175 eval.c Added type checking to the above cases.
2176 value.h Added not_lval_constant to the lval_type ennumerated type.
2177 not_lval_constant means that the value is a constant
2178 value; that is 3 or 'a' or TRUE, not as in a constant
2179 identifier. This is used to help coerce numbers such as 3
2180 to either signed or unsigned numbers.
2181 valops.c Added the function value_coerce_constants() which coerces
2182 constant integers as following: if one is a constant and
2183 the other is not, the constant's type is set to the type
2184 of the other argument. If both are constants and one is
2185 signed, the other is converted to a signed constant.
2187 Sat Jun 29 17:26:29 EDT 1991
2189 valarith.c Added a better range checker. It now checks range
2190 (successfully) on integral operations [+-] (signed and
2191 unsigned) for any C sized type. Still does not work well
2192 for multiplication.)
2193 int_in_size() returns an integer that is coerced to fit into
2194 specified number of bytes.
2196 Mon Jul 1 13:04:14 EDT 1991
2198 language.[ch] Added the function binop_result_type(), which returns the
2199 builtin (struct type *) type that would be the result of a
2200 binop on the two values V1 and V2.
2202 Wed Jul 3 19:22:53 EDT 1991
2204 source.c Extended source_info() to include the source language in
2205 the output from "info source".
2207 Fri Jul 5 13:48:52 EDT 1991
2209 utils.c Moved the support functions for the GDB set/show commands
2210 dealing with language into language.c.
2211 language.c Added the function language_info(), which displays info
2212 about the current working language, type and range check
2213 settings. Called via the GDB command "info language".
2214 Added an initialization routine _initialize_language(),
2215 that sets defaults for the language, type and range
2216 variables and sets up the new GDB commands.
2217 main.c Language setup moved to language.c.
2220 Mon Jul 8 10:10:22 EDT 1991
2222 valarith.c Debugged the range checker for arithmetic. Still does not
2223 work for multiplication very well.
2225 Mon Jul 8 12:40:37 EDT 1991
2227 language.[ch] Added the function value_true() which returns non-zero if
2228 its argument represents a boolean true value.
2229 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
2230 check the truth of an expression.
2232 Thu Jul 11 12:51:34 EDT 1991
2234 language.[ch] Added the predicate structured_type(), which returns
2235 non-zero if the argument is a structured type.
2236 Added the predicate pointer_type(), which returns non-zero
2237 if the argument is a pointer type.
2238 eval.c Added the ability to do addition and substraction on
2239 pointers and integers. This case simply bypasses the
2242 Thu Jul 11 14:41:42 EDT 1991
2245 Added the symbol N_DEFD (0x4a) which is a definition
2246 module dependency that is used by the GNU Modula-2
2247 compiler and the linker. It is not important to GDB,
2248 except that [dbx|coff|mips]read.c should ignore these
2251 Fri Jul 12 16:07:00 EDT 1991
2253 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
2254 0 in val_print(). Also added statements to the else part
2255 to coerce type (argument to val_print) to a pointer type
2256 if it is an "array of unspecified length".
2257 valops.c Added the function value_m2_string(), which returns a
2258 (value) value which is a constant string, whose type is
2259 (ARRAY [0..n] OF CHAR). The length field of the type
2260 structure is set to zero, so it will be interpreted as an
2261 "array of unspecified length".
2262 stack.c Moved the language/frame mismatch check to
2263 main.c:execute_command().
2264 main.c The working language is recorded each time
2265 execute_command() is executed. If working lang has
2266 changed during its execution, then the new
2267 language/type/range info is printed out for the user. If
2268 the working language does not match the language of the
2269 frame, a warning is issued.
2271 Sat Jul 13 16:16:39 EDT 1991
2273 eval.c Moved all the type-checking stuff for operators to
2274 language.[ch] language.c. This is so we can keep language-specific
2275 stuff (like for what type operators are defined) in
2277 language.[ch] Added the function binop_type_check(), which checks to see
2278 if its two (value) arguments are type-compatible with its
2279 opcode argument. The opcode should represent an operation
2280 involving an operator. Also added the macro function
2281 unop_type_check, which calls binop_type_check with a
2282 NULL second argument.
2283 expprint.c Added Modula-2 operators to the op_print_tab, so info
2284 expression.h break works correctly. Also added "op_string", which
2285 returns the string corresponding to the (enum exp_opcode)
2286 opcode that is its argument.
2289 Sat Jul 13 18:26:18 EDT 1991
2291 coffread.c Added code to record the type of function arguments with
2292 each paricular function. Code is very similar to that
2294 dbxread.c Moved add_param_to_type() to symtab.c
2295 symtab.[ch] Added function add_param_to_type() from dbxread.c
2297 *** NOTE: The above additions have not been tested.
2299 Mon Jul 15 12:50:47 EDT 1991
2301 langauge.[ch] Added the functions type_error and range_error, which work
2302 like error() except if the type/range mode is set to
2303 *_mode_warn, then they do not do a return_to_top_level(),
2304 but merely print a warning.
2305 Also changed [set|show]_[type|range]_command() to support
2306 the new "warn" feature.
2308 Thu Jul 18 17:50:54 EDT 1991
2310 mipsread.c Added code to record the type of function arguments with
2311 each particular function. Code is very similar to that
2314 *** NOTE: The above additions have not been tested.
2316 Fri Jul 19 11:19:10 EDT 1991
2318 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
2319 UMIN_OF_SIZE, which when given a size of a numeric type,
2320 return the maximum and minimum value it can hold. UMAX...
2321 and UMIN... return the result for unsigned types.
2322 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
2323 struct types. They call above macros.
2324 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
2325 avoid a name conlict with the above.
2326 c-exp.y Added range checking on numeric constants in
2327 parse_number() for completeness.
2328 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
2329 return 0 if working_lang is not language_c.
2331 Thu Aug 8 14:17:22 EDT 1991
2335 breakpoint.c Documentation strings of some commands changed to
2336 eliminate the references to the C language where
2339 Tue Aug 13 15:48:03 EDT 1991
2341 m2-exp.y Added qualified identifiers to the grammar. The semantics
2342 are slightly different from those of the GDB operator ::
2344 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
2345 type_exp, where type_exp is any valid type expression.
2347 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
2348 printcmd.c Modified ptype_command() so it actually parses the input
2349 (necessary for type expressions with scope qualifiers).
2350 Added the function ptype_eval() which expects an
2351 expression composed of one OP_TYPE element.
2352 *.[ch] Replaced all occurences of parse_c_expression with
2354 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
2356 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
2358 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
2360 Small fixes from Peter Schauer:
2362 * infrun.c (child_attach): Lint.
2363 * solib.c (find_solib): Handle shared libs version 2.
2365 Small fixes from David Wood:
2367 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
2371 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
2372 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
2374 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
2375 chars_per_line is at maximum (user typed `set width 0'). Fix
2376 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
2378 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
2380 * coredep.c: include ptrace.h where necessary.
2381 * mipsread.c(parse_lines): fix unsigned char problem that was
2382 messing up line numbers on SGI's and possibly other MIPS based
2384 * infrun.c (child_create_inferior): use better test to check
2385 return val from setpgrp().
2386 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
2387 for sgi/irix support.
2389 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
2391 * mipsread.c (parse_symbol): Put non-static procedures
2392 in the global block.
2394 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
2396 Patch together `text_start' and `text_end' for 29K port.
2398 * exec.c (exec_command): If NEED_TEXT_START_END, define the
2399 variables and set them based on the exec file.
2400 * am29k-tdep.c: declare text_start.
2401 * valops.c (call_function_by_hand): declare text_end.
2403 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
2404 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
2405 because machines that do this will also have to know to
2406 set NEED_TEXT_START_END. Besides, it was a redundant way to
2408 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
2409 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
2410 NEED_TEXT_START_END.
2412 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
2414 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
2416 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
2417 Pass MUNCH_DEFINE to munch whenever we run it.
2418 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
2419 format string; use 0x%x instead.
2420 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
2421 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.

2430 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
2431 Merge target arm case with other "easy" cases. Add target
2432 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
2433 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
2435 * minimon.h, remote-adapt.c, remote-mm.c: Add.
2436 * munch: Cope with RT/PC putting fns in data segment.
2437 Restore ability to override `nm' by specifying MUNCH_NM.
2438 * xconfig/rtbsd, xconfig/ultra3: New host systems.
2439 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
2440 and remote-adapt. Remove encapsulated coff #define's (the
2441 support should go in BFD, and gdb shouldn't know or care).
2442 * tconfig/a29k-kern: Same, but for remote kernel debugging.
2443 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
2444 * tm-29k.h: Update BADMAG (though it should go away).
2445 Allow the register definitions to be overridden in another
2446 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
2447 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
2448 DUMMY_SAVE_GR96, for handling kernel calling conventions
2449 that use GR64+ rather than GR96+.
2450 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
2451 remote debugging of Ultra3 kernel. Includes tm-29k.h and
2452 overrides various things.
2454 * remote-mm.c (mm_attach, mm_wait): Handle attach like
2455 child_attach does, making a clean stop in the newly attached
2457 * remote-eb.c: Lint.
2459 * coffread.c: Make coffread independent of any particular
2460 variant of COFF. Avoid #include-ing any particular one except
2461 internalcoff.h. BFD now passes key values for symbol reading
2462 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
2463 and the symbol masks and shifts); use them.
2464 Remove obsolete end_of_text_addr.
2466 * exec.c: Remove unused include files.
2468 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
2470 * Makefile.in (documentation targets): Pass $(M4).
2471 Bugfix from eggert@twinsun.com (Paul Eggert).
2473 * stack.c (down_silently_command): Check for stack existence.
2475 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
2477 * Makefile.in (VERSION): Update to 4.0.3.
2479 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
2481 * core.c (core_file_command): Print frame at coredump with
2482 its level number, by calling print_stack_frame.
2483 * frame.h: Add selected_frame_level, print_stack_frame.
2484 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
2485 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
2486 Change print_sel_frame and print_selected_frame callers to
2489 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
2490 * symfile.c (free_named_symtabs): Ditto.
2491 * main.c (main): wrap_here needs an arg.
2492 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
2493 (solib_add): Avoid noise.
2494 (solib_create_inferior_hook): Lint.
2495 (sharedlibrary_command): Move dont_repeat to here.
2496 * utils.c (error): Call wrap_here to force buffered output.
2498 Small patches from Peter Schauer:
2500 * coffread.c (start_symtab): Free any existing line_vector before
2502 (read_coff_symtab): Ditto for type_vector.
2504 * source.c (lines_to_list): New variable, replacing function.
2505 (all uses): Use as variable.
2506 (_initialize_source): Add 'set listsize' and 'show listsize'.
2507 * utils.c (lines_to_list): Remove function.
2508 * stack.c (print_frame_info): Use as variable.
2509 * defs.h (lines_to_list): Remove declaration.
2511 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2513 * breakpoint.c (insert_breakpoints): Restore warning about
2514 the program might be running in another process, but only for
2515 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
2516 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
2518 * utils.c (error): if error_pre_print is set, print the string
2520 * main.c (main, print_gnu_advertisement, print_gdb_version):
2521 Reformat legalese so it always prints, but acts as an "I'm here"
2522 message while symbols are being read. If any errors occur,
2523 print a few newlines to set off the message and start it at the
2524 left margin. Remove mention of "help" command, and don't yak
2525 about symbol reading.
2526 (catch_errors): Error string is now printed first in case of
2528 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
2529 suggest the "help" command.
2531 * Makefile.in (VERSION): Set to 4.0.2.
2533 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
2535 * .gdbinit: Remove useless "rr" command. Set complaints
2536 to 1 for people debugging gdb.
2538 * breakpoint.c, remote-vx.c: Reword strings printed by
2539 catch_errors callers.
2541 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
2543 * WHATS.NEW: "history write -> history save". Doc "write on/off".
2544 (Fix from kenc@viewlogic.com.)
2546 Fix some infrastructure to be able to cope with host and target
2547 machines with different sized basic types (ints, ptrs, etc).
2548 (Idea from pierre@la.tce.com (Pierre Willard).)
2550 * values.c (value_from_longest): Rename from value_from_long.
2551 Handle pointer types as well as integers, so that targets with
2552 different pointer sizes from the host can be accomodated.
2553 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
2554 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
2555 uses of value_from_long to value_from_longest.
2556 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
2557 the correct pointer type to value_from_long{est}.
2559 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
2561 * remote-vx.c: Remove obsolete code for calling functions via
2562 vxworks kludge interface (it referenced value_from_long).
2564 * valops.c (value_string): Find malloc with lookup_misc_func, not
2567 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2569 Make writing to files work properly. (Fixes to BFD are also needed.)
2571 * core.c (core_open): Open file ourselves, read or r/w, depending on
2572 write_files. Use bfd_fdopenr.
2573 * gdbcore.h (write_files): New variable.
2574 * exec.c (write_files): Define variable, add set&show for it.
2575 (exec_file_command): Use write_files to open for read or r/write.
2577 Make shared library reading happen automatically. These changes
2578 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
2580 * inferior.h (stop_soon_quietly): Add to exported variables.
2581 * infrun.c (child_create_inferior): call solib hook, if defined.
2582 (child_attach): call solib hook, if defined.
2583 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
2584 (find_solib): Use lookup_misc_func rather than hand-rolled.
2585 (symbol_add_stub): New stub for catch_errors.
2586 (solib_add): Avoid output if !from_tty. Catch errors rather
2587 than just calling symbol_file_add and bombing.
2588 (solib_create_inferior_hook): Interface with the target process
2589 to let it read and alloc shared libs, then figure out what it did.
2591 * core.c (validate_files): Fix typo, soften warning.
2592 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
2594 * utils.c (fputs_demangled): Avoid duplicate printing if
2595 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
2597 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
2598 (Fix from pierre@la.tce.com (Pierre Willard).)
2600 * main.c (catch_errors): Change argument to a char * from an int,
2601 since a char * can point to a struct full of glop, but an int
2602 is not guaranteed to be able to hold a pointer.
2603 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
2604 breakpoint_re_set_one, breakpoint_re_set): Adapt.
2605 * core.c (core_open, solib_add_stub): Adapt.
2606 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
2608 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2610 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
2611 by adding .NOEXPORT target.
2613 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2617 * Makefile.in (VERSION): Roll to 4.0.
2618 (gdb.tar.Z): Make refcard.ps as well, for shipment.
2620 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2622 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
2625 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
2628 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
2630 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
2631 reflect above name change
2633 * WHATS.NEW: correct pointer to refcard.
2635 * doc/gdb.texinfo: update New Features, Installing
2637 * doc/gdbint.texinfo: add short description of configure +template
2639 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2641 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
2643 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
2645 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
2646 tar file, add dependencies for referenced doc files.
2648 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
2650 * coffread.c, symfile.c, stack.c: saberized.
2652 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2654 * doc/refcard.tex: permuted Essential Commands sec
2656 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
2658 set/show symbol-reloading
2659 default set complaints 0
2661 RET-repeat disabled after prompted long displays
2662 processID (attach) interpretation of 2nd GDB cmdline arg
2664 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
2666 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
2667 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
2668 breakpoint.c, main.c: lint.
2670 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2672 Install new configuration scheme for GDB and friends.
2674 * config.sub: Translate ordinary names to three-part names.
2675 * configure: Use three-part names internally.
2676 * configure.in: Translate three-part names to filenames.
2678 * README, WHATS.NEW: Update for gdb-4.0.
2679 * Makefile.in: Roll VERSION to 3.99.
2681 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
2683 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
2684 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
2685 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
2686 to single structures rather than arrays; when passing
2687 their address, use &. This avoids trouble with bdead compilers.
2688 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
2689 instead. This avoids portability headaches.
2690 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
2692 * source.c (open_source_file): Avoid ANSI const bdeath by
2693 skipping declaration and then casting result value.
2694 * tm-hp300bsd.h: Clarify comment.
2695 * utils.c (strstr): Result is const char *; ANSI bdeath.
2696 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
2697 since system include file defines it differently from "defs.h",
2698 though the two are equivalent for our purposes.
2699 * tconfig/hp300bsd: Add m68k-tdep.o.
2701 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
2703 * tconfig/sun*4: Remove warnings about system assembler.
2705 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2707 * mcheck.c: Avoid warning about undeclared abort fn.
2708 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
2709 it causes recursive calls to error() when used in cleanups.
2710 To do so requires that we make it a function, so we do.
2711 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
2712 * utils.c (do_cleanups): Remove the current cleanup from the
2713 chain *before* calling it, in case error() is called from it.
2714 The result won't be pretty, but won't be an infinite loop either.
2716 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
2718 * dbxread.c (read_struct_type): Grok anon structs for C++.
2719 (vb_name, vptr_name): Null terminate these strings.
2721 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2723 Minor bug fixes from BSD Net2 gdb:
2725 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
2726 returns 0, there is no previous frame.
2727 * breakpoint.c (commands_command): If !from_tty, don't call
2728 input_from_terminal_p().
2729 * dbxread.c (record_misc_function): Speed up slightly.
2730 (compare_psymbols): Ditto.
2731 * infcmd.c (do_registers_info): Take a second argument to
2732 determine whether to print float registers. "info registers"
2733 does not do so anymore. "info all-registers" does, now.
2734 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
2736 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
2737 * inflow.c (initialize_inflow): Set tflags_ours correctly.
2741 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
2742 executing_breakpoint_commands if we are interrupted by error.
2743 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
2744 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
2745 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
2746 catch_errors() so we can setup the frame regardless of whether
2747 the shared libs work.
2748 * ieee-float.c (double_to_ieee_extended): Get exponent from
2749 right place in little-endian systems. From John Carey.
2751 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2753 * main.c: Remove unused terminating_signals and catch_termination().
2754 (long_options): Terminate with a zero element.
2755 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
2756 (gdb_readline): Make call-compatible with readline.
2757 (init_signals): Improve comments re vfork vs. signal.
2759 * utils.c (prompt_for_continue): Use new gdb_readline().
2760 If we prompt for continuation, we don't let CR repeat the previous
2761 command, once we get back to a prompt. It's too easy to keep
2762 hitting CR, expecting "--more--" prompts, and have some long
2763 command start repeating on you.
2765 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2767 * blockframe.c (frameless_look_for_prologue): Speed up by
2768 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
2769 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
2770 Define two variants, one faster.
2771 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
2772 and return zero, rather than giving an error.
2773 (setup_arbitrary_frame): Initialize the PC in the new frame.
2774 (skip_prologue): Add a second arg saying whether we're just
2775 checking for a frameless function or not.
2777 * core.c (core_open, core_close, core_xfer_memory): Move
2778 section table pointers and bfd* into the target_ops.
2779 (core_open): Allow errors in shared lib reading, etc.
2780 (core_files_info): Describe shared library sections.
2782 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
2783 exec_files_info, set_section_command): Move section table
2784 pointers and bfd* into the target_ops.
2785 (add_to_section_table): Add BFD to section table.
2787 * target.c (target_xfer_memory, target_info): Pass target to
2788 xfer_memory and target_info functions.
2791 * gdbcore.h: Move struct section_table.
2792 * target.h: New home of struct section_table.
2794 * solib.c (solib_add): New argument is the target_ops whose
2795 section list is to be added to, if any. Reallocate the
2796 sections in that target to add any that come from shared libs.
2797 (throughout) so_sections renamed to sections.
2798 (solib_xfer_memory): Deleted.
2799 * tm-sunos.h (SOLIB_ADD): Add target argument.
2800 (SOLIB_XFER_MEMORY): Delete.
2802 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2803 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
2804 from target_ops. It's the same on all targets. Add two section
2805 pointers to target_ops.
2807 * stack.c (find_relative_frame): Dump ancient algorithm for
2808 "down", just use handy "next" pointers.
2809 (frame_command): Don't error if there is no stack; let user
2812 * inflow.c (new_tty_prefork, new_tty): New prefork routine
2813 modifies static state in the parent process; new_tty itself
2814 runs in the child and modifies the child's file descriptors
2815 to match the saved static state.
2816 * infrun.c (child_create_inferior): Call new_tty_prefork,
2819 * infptrace.c (child_xfer_memory): Add ignored target arg.
2820 * remote-eb.c (eb_xfer_inferior_memory): ''
2821 * remote-nindy.c (nindy_xfer_inferior_memory): ''
2822 * remote-vx.c (vx_xfer_memory): ''
2823 * remote.c (remote_xfer_memory): ''. Rename from
2824 remote_xfer_inferior_memory.
2826 * main.c (main): Only try to attach "corefile" argument if
2827 it starts with a digit.
2829 * symfile.c (symbol_reloading): New "set/show" variable.
2830 (symbol_file_add): Shorten message about symbol reading.
2831 (add_symbol_file_command): Merge with add_syms_addr_command,
2832 since this should work on all targets now.
2833 (stop_whining): Default to zero, to shut up complaints
2834 about bad symbol tables on many systems.
2835 (free_named_symtabs): Just exit unless symbol_reloading.
2837 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
2838 and add comment explaining shared library screw.
2840 * source.c: #if defined => #ifdef.
2842 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2844 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
2846 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2848 * doc/rdl-apps.texinfo: provide default readline-appendix finder
2849 (doc/Makefile knows how to make one for local config)
2851 * Makefile.in: use doc/Makefile for doc targets
2853 * doc/Makefile: GDB documentation now has its own Makefile
2854 doc/refcard.tex: renamed from "gdbrc.tex"
2855 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
2856 doc/gdbint.texinfo: add markup in "Cleanups" chapter
2859 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2861 * values.c (baseclass_addr): When reading target memory, use the
2862 length of the basetype, not the upper type. We've only malloc'd
2863 enough space for the basetype, leading to errors in free().
2865 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
2866 ends up as a function specially, since we know the actual type of
2867 the pointed-to address. This (somewhat) fixes display of
2868 expressions that include misc_function_vector names. Try `cond 1
2869 !strcmp("a","b")' then `i b'.
2871 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
2872 The child can be proceeded from inside wait_for_inferior in
2873 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
2874 getting skipped in that case.
2876 * expprint.c (print_subexp): Use filtered output, since the
2877 subroutines we call use it, otherwise the output is horribly
2878 mangled, since output of wrappable stuff comes out late.
2880 * Makefile.in: Bump VERSION to 3.98.1
2882 * infrun.c (child_create_process): Use execlp to find the
2883 shell to exec our target program. This requires some fiddling
2884 with `environ' since there is no execlpe().
2886 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2888 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
2889 Minor rearrangement of refcard permits two new make targets--
2890 gdbrc.dvi DVI output for refcard, using CM fonts
2891 gdbrc.ps PostScript refcard, using PS fonts
2893 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2897 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
2898 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
2900 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2902 * doc/gdb.texinfo: last changes for release.
2903 Minor typo and formatting fixes; incorporated most fixes remaining from
2904 filed mail commenting on earlier drafts.
2906 Added warnings: pipes don't work in run command;
2907 conditions are converse of assertions;
2908 step over fn without debug info goes to next fn;
2909 vars may have "wrong" values near fn entrance, exit
2911 Added example from Kingston on printing repeated nonadjacent values
2913 Added explicit mention that in Emacs gdb mode C-c and C-z are like
2914 shell mode for signals
2916 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
2917 doesn't sound so much like its parent "Stopping and Continuing"; also
2918 moved entries on continue to top of section, so they don't get lost.
2920 Improved installation directions in appendix, added manual formatting
2923 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2925 * configure.in: Remove xm.h and tm.h even if we aren't linking
2926 new ones, so "./configure sun4; ./configure none" does the right
2927 thing. Assume that alldeps.mak and depend are already built in
2928 srcdir, and avoid running "make" (particularly "make depend",
2929 which involves "gcc") from inside configure. Build Makefile
2930 directly rather than building Makefile.conf first.
2931 * configure: Regenerate with above changes.
2932 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
2933 to 3.98. Revise gdb.tar.Z procedure to produce a file
2934 called gdb-$(VERSION).tar.Z but which unpacks into a
2935 directory called "gdb". Move non-source files out of
2936 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
2937 (depend): Don't try to do "gcc expread.y".
2938 (expread.o): Update dependencies by hand.
2940 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2943 Fixed a variety of small typos that prevented info from formatting
2944 cleanly; altered too-long heading for GPL Appendix, as discussed
2945 w/RMS; Changed date on cover to July 91.
2947 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2950 (1) Applied some fixes due to comments from Larry Breed (easier ones
2951 through chapsec 5.2)
2952 (2) Eliminated use of @footnote---had my doubts about it anyways, and
2953 it's broken in latest texinfo
2954 (3) Introduced *some* use of [] for optional arguments, where
2955 explanation is not simpler by listing cmd w arg and cmd w/out arg
2956 separately. Still not using @deffn.
2957 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
2958 couple of headings are too long. Need patches to texinfo or revision
2961 * Partial update to README (which still needs work for this
2962 release!): (1) use of configure corrected for new script,
2963 (2) "make gdb.dvi" and "make gdb.info" mentioned.
2965 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
2967 * symtab.c (lookup_symbol): Don't complain right off about
2968 no debug symbols; use the misc function vector first.
2969 (list_symbols): Use misc function vector to find symbols
2970 that don't have debug info, and print them.
2971 (find_pc_symtab): Temporarily avoid fatal() when psymtab
2972 PC range doesn't match symtab PC range, as it does on the
2973 MIPS because our symtab reading isn't perfect.
2975 * dbxread.c (dbx_symfile_read): Make warning about
2976 "no debug symbols" slightly nicer.
2978 * source.c (select_source_symtab): If "main" symbol exists,
2979 but decode_line_spec can't find line info, don't just return
2980 a zero; try other source symtabs or give an error.
2982 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
2983 their low addresses first, then rip through fixing high addrs.
2985 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
2986 <runene@ifi.uio.no>.
2987 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
2989 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2991 * Minor, mostly mechanical, cleanup of doc subdir for clean
2992 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
2993 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
2995 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
2997 Mostly MIPS and general symbol-reading fixups.
2999 * doc/gdbint.texinfo: Add documentation on symbol-reading
3002 * mipsread.c: Remove kludges around #include "ecoff.h".
3003 Remove redefinitions of a_magic, etc, no longer used.
3004 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
3005 Fix global overview comments to match symfile.c protocol.
3006 (mipscoff_new_init): Eliminate cur_hdr if we have one.
3007 (mipscoff_symfile_read): Eliminate unused code. Avoid
3008 sorting all the symtabs, when all we have read here is psymtabs.
3009 The symtabs are sorted as they are created anyway. Tell
3010 condense_misc_bunches whether we're mainline.
3011 (psymtab_to_symtab_1): Pass filename when recursing, to make
3012 stack trace more informative.
3013 (parse_partial_symbols): Assume cur_hdr as argument.
3014 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
3015 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
3016 the TYPE_NAME of char *, since that's done in symfile.c.
3017 (free_numargs, parse_symbol, add_symbol, add_block,
3018 shrink_linetable): Declare these fns void.
3019 (upgrade_type): Convert tree of if's to switch. Clean up
3020 bogus "off == 0" handling with a complaint. Avoid setting
3021 field bitpos and bitsize of array with lower and upper bounds.
3022 Check specified bitsize of elements against their actual type's
3023 bitsize, and complain if different. Complain about unknown
3025 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
3026 (psymtab_to_symtab_1): Print names of subsidiary files that
3027 are being read in. FIXME, we read far too many files. This code
3028 is not the problem, the problem is in parse_fdr where the psymtabs
3030 (cross_ref): Result should indicate that we used one aux entry
3031 normally, or two if we encountered a "next" entry. This used
3032 to leave the caller pointing at the wrong aux entry.
3033 (add_symbol): If overflowed cur_block, reallocate it larger,
3034 chase all pointers to it, and complain(), rather than clobber memory.
3035 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
3036 (new_field): Only allocate one field initially, not two.
3037 Pull ++ out of macro argument. Simplify.
3038 (_initialize_mipsread): Avoid initialization of importd
3039 global_psymbols and static_psymbols.
3041 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
3042 to properly set pst->symtab; avoid searching for it.
3043 (symfile_fns): Improve comments, add a FIXME.
3044 * dbxread.c: Update comments to reflect symfile protocol.
3045 (read_ofile_symtab, end_symtab): Return the symtab.
3046 (psymtab_to_symtab_1): Set pst->symtab.
3048 * coffread.c (coff_symfile_read): tell condense_misc_bunches
3049 whether we're mainline.
3051 * symfile.h (sym_fns): Remove unused sym_discard member.
3052 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
3054 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
3055 the environment variable is not.
3056 * infcmd.c (finish_command): Use filtered printfs.
3057 * cplus-dem.c: Add struct tags to a few unnamed structs.
3058 * valops.c (value_coerce_array): Improve comments.
3059 * valprint.c (type_print_varspec_suffix): Print array size only
3060 if greater than zero.
3061 * m88k-tdep.c: Shift some lines left by one space, that had
3062 apparently been trashed at some point.
3063 * TODO: More things to do, a few got done.
3065 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3067 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
3068 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
3070 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
3071 * expread.y, findvar.c, symmisc.c: Ditto.
3072 * printcmd.c (address_info): Update printed forms of LOC_
3073 symbols. Elim LOC_EXTERNAL.
3074 (print_frame_args): Keep track of param stack offsets before
3075 re-looking up to find the local register param is kept in.
3077 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
3078 Further integration of mipsread into gdb. Eliminate unused
3079 routines, duplicate declarations. Handle static symbols in
3080 psymtabs as well as external symbols. When reading symtabs,
3081 insert symbols into the correct block (global, static, or a local
3083 (read_mips_symtab, parse_partial_symbols): Don't pass useless
3085 (mipscoff_symfile_read): Don't call select_source_symtab.
3086 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
3087 rather than SYMBOL_VALUE.
3088 (parse_external): Comment clobbering of top_stack.
3089 (parse_partial_symbols): Update comments. Allocate and parse
3090 static symbols as well as external symbols. FIXME, enum values
3091 are not handled in this pass, but should be. Inline new_psymbol.
3092 Use SYMBOL_VALUE_ADDRESS.
3093 (psymtab_to_symtab_1): Read symbols into global static block
3094 by default (until enter some function's local block context).
3095 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
3096 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
3098 * source.c (select_source_symtab): Select a source symtab
3099 from either the symtabs or, failing that, the psymtabs.
3100 (list_command): Update error message.
3101 (forward_search_command, reverse_search_command): Use getc, not
3102 fgetc, for speed. FIXME, add comment about buffers that die if
3103 overrun by long line.
3105 * values.c (unpack_field_as_long, modify_field): Avoid shifting
3106 by an entire word, which is not portable, if we have a 32-bit
3107 field. (Code in dbxread.c already turns such bitfields, if
3108 aligned, into ordinary ints, but fixing this will help for other
3109 symbol formats and for future changes.)
3110 * core.c (core_open): Handle ANSI const brain death.
3111 * utils.c (vprintf): Fix varargs typo.
3113 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3115 * findvar.c (find_var_value): Handle &function better.
3116 * TODO: Document work needed on &fn and &array.
3117 * printcmd.c (print_address_symbolic): New arg is the prefix
3118 to print if a name is printed.
3119 (print_address_demangle): Honor "set print address" now.
3120 Use new arg above to improve spacing of output.
3121 * valprint.c (val_print): When printing function pointers,
3122 print symbolic form too.
3123 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
3125 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3127 * core.c (memory_error): Reword error msg to mislead less.
3129 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
3131 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
3132 parse_partial_symbols): Use newer BFD internals (external_filehdr
3133 and external_aouthdr), byte-swap the fields that we care about
3134 before using them, and make the file header data local to
3135 read_the_mips_symtab rather than global.
3137 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
3139 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
3140 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
3142 * main.c (command_line_input): Flush stdout and stderr
3143 before every call to readline. This reportedly fixes a bug
3144 that comes up in Sys V running emacs-gdb and/or xxgdb,
3145 when stdin/out are pipes or sockets.
3147 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
3149 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
3150 Avoid declaring Makefile dependencies, because GNU Make stupidly
3151 tries to update it if we do.
3153 * coffread.c: Revise for minor changes to bfd internal coff
3156 * configure: If -template= is given a relative path, make it
3157 absolute before recurring in subdirectories.
3159 * configure, configure.in, Makefile.in: Install "configure" script
3160 as replacement for config.gdb.
3161 * config.gdb, Makefile.dist, Makefile.sdir: Remove
3162 * README: Update for configure, mostly. FIXME.
3164 * Add dec3100 as equivalent to littlemips. Indicate in all host &
3165 target config files that they are for the host. When the lines
3166 get copied into the Makefile, this makes it more obvious what's
3169 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3171 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
3172 tabs, which end up in the disassembler output inadvertently.
3174 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
3176 Make it compile cleanly in an ANSI GCC2 environment.
3178 * blockframe.c: <stdio.h>
3179 * cplus-dem.c: free takes a void *, ifdef __STDC__
3180 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
3182 * defs.h (alloca): Avoid doing anything if alloca already def'd.
3183 * stddef.h, stdlib.h: Remove these files.
3184 * symtab.c: Avoid declaring qsort, close.
3185 * symfile.c: Avoid declaring close.
3186 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
3187 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
3189 Assorted other changes.
3190 * dbxread.c: include "libaout.h", not "liba.out.h".
3191 * printcmd.c (print_frame_args): Set recurse properly for
3192 indentation of struct and array parameters.
3193 * valops.c (value_cast): Allow cast to void.
3194 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
3195 single_step() in a target-independent fashion.
3196 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
3197 set up to be ready to continue. This makes us target independent.
3198 * infptrace.c (child_resume): Remove call to single_step; now
3199 can single step a SPARC target of any kind.
3201 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
3203 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
3204 docn into separate sections---basically chapters, plus two loose
3205 pieces that can be configured to go in different places. This
3206 allows GNU m4 to preprocess the manual without coredumping.
3208 * Makefile.dist: tell TeX where to find texinfo.
3210 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
3212 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
3213 the new target "rdl-apps.texinfo" which captures the Makefile
3214 variable that records where to find the Readline libraries.
3216 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
3218 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
3219 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
3220 * defs.h (const, volatile): Only define if not already defined.
3221 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
3223 * README: Update for release 3.95.
3224 * config.gdb: Don't create readline dir in subdir builds.
3225 * main.c: Include with "..." form for non-system include files,
3226 so "gcc -MM" for "make depend" works.
3227 Include readline files with "...h" rather than <readline/...h>.
3228 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
3230 * coffread.c: Undo minor damage done by Rich Pixley. Use
3231 different internal and external representations of COFF
3232 data structures. Use new BFD routines for swapping them in and
3234 * symfile.c (free_named_symtabs): Avoid freeing file names that
3235 are null or empty. Old i960 tools seem to produce files that
3236 claim to have empty names, causing each successive file read
3237 to blow away the previous one.
3238 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
3239 Move deferred_stores to top of file, but don't separate its
3240 #define's from its variable. Add commentary.
3241 * Makefile.dist: Fix Rich damage; undo "configure" changes in
3242 favor of keeping the (working) config.gdb. Move readline
3245 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
3247 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
3249 * infptrace.c (fetch_registers): no result, since now void.
3250 * tconfig/news: target depends on m68k-tdep too.
3252 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
3254 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
3257 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
3258 applied various small fixes due to or inspired by RMS comments
3260 * doc/gdb.texinfo: finished using all RMS comments, save those for
3261 appendices on readline and cmd history (which are in other source
3264 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
3266 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
3267 chapter 9; (2) documented 'break' command's menu mode for
3268 overloaded names, in response to hgs problem report C++ p-31
3270 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
3272 * doc/gdb.texinfo: (1) better introductory example; (2) more
3273 consistent use of @code, @samp, @file, @kbd throughout; small
3274 cleanups to first three nodes; (3) new "Contributors" node;
3275 (4) Appendix, Renamed Commands; (5) divert specialized startup
3276 instructions to "Targets" chapter for generic manuals, while
3277 leaving them up front for manuals specific to specialized
3278 environments; (6) apply fixes from RMS comments through chapter 4.
3280 * pretex.m4: modify explanatory text slightly (and redefine
3281 "regexp") to keep GNU m4 from complaining. (It still crashes
3282 later, but one step at a time...)
3284 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
3286 * readline/readline.c (update_line): Avoid dereferencing a pointer
3287 before comparing it to its bounds. Saber caught this.
3288 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
3289 and only set PC if tgetstr returned non-null. Saber caught this.
3291 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
3293 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
3294 stuff for config manual) here where it counts; updated
3295 to use new subdir structure (gdb/doc/).
3297 * Makefile: generated from above via
3301 * gdbint.texinfo: added instructions on generating gdb.info* files
3302 locally for release. These are ordinary info
3303 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
3304 Makefile)---but due to use of texinfo 2, can't count on makeinfo
3305 to generate these, so we distribute them already formatted.
3307 * gdb.texinfo: included full Info node and menu crud (as generated
3308 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
3310 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
3311 put in comments-for-future gdb.info target (one day makeinfo will
3314 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
3316 * gdb.texinfo: Updated to include new or old undocumented
3317 commands, at least the following (perhaps some others I forgot to
3318 record): info f, info float, info path, info program, info s, info
3319 set, info source, info terminal, info types, info user, set/show
3321 Also covered all recent GDB command renames for v4.
3323 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3325 * mipsread.c: Rather than keeping count of how many symtabs
3326 and psymtabs we have, for sorting purposes, count them when
3327 we need to sort. This fixes bug in rereading of symbol tables.
3329 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
3331 * infcmd.c: renamed "info path" to "show paths"
3332 * gdbrc.tex: documented above.
3334 Wed May 8 04:51:11 1991 John Gilmore (gnu at cygint.cygnus.com)
3336 * remote.c: Fix comments.
3337 * utils.c (error): Force out any pending wrap output.
3339 Sat May 4 11:11:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3341 * Makefile.dist: Roll VERSION to 3.95.
3342 Fix up "saber_gdb" to work again.
3343 * saber.suppress: Update.
3345 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
3346 symtab.h, target.c, target.h: Lint.
3347 * core.c: setup and select frame after reading shared libs,
3348 else reading shared libs will clobber them. Lint.
3349 * utils.c (error): Force out any buffered wrap text.
3351 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
3353 * remote.c: Remove decls of memory_insert_breakpoint
3354 and memory_remove_breakpoint, no longer used. (Suggestion of
3357 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
3358 to make it easier to interface to "configure"'d libraries.
3360 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
3362 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
3363 aliases for set/show print.
3365 Thu May 2 11:22:02 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
3367 * coffread.c (coff_sym_fns) [TDESC]: Make the type be m88kbcs.
3369 * m88k-tdep.c (IEEE_isNAN): New function.
3371 * infrun.c, m88k-tdep.c, m88k-xdep.c: Change
3372 initialize_{tdesc,dcontext} to init_{tdesc,dcontext}.
3374 * infrun.c [TDESC]: Add a bunch of crud.
3376 * xm-88k.h [__GNUC__]: Don't define memset.
3378 * m88k-xdep.c: #if 0 out push_breakpoint.
3380 * tm-88k.h: Define GET_SAVED_REGISTER.
3382 * tm-88k.h: Define DGUX.
3384 * m88k-opcode.h (UEXT, SEXT, MAKE): Put parentheses around arguments.
3386 * m88k-pinsn.c (sprint_address): Declare at top of file.
3388 * m88k-xdep.c: #if 0 out core_file_command.
3390 * values.c ({unpack_,value_as_}pointer): Just call

3864 Sun Apr 14 23:08:34 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
3866 * inftarg.c (child_open), remote-vx{,.68}.c (vx_proc_open):
3867 New function to give correct error message.
3869 Thu Apr 11 17:19:41 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
3871 * target.h: Add to_doc and target_preopen.
3872 target.c: Add target_preopen and target_command.
3874 (add_target): Call add_cmd and mess with targetlist->doc.
3875 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
3876 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.
3877 Call target_preopen from open routine.
3879 * main.c: Rename editing_info to show_commands.
3880 (_initialize_main): Rename "info editing" to "show commands".
3882 * source.c: Rename directories_info to show_directories.
3883 (_initialize_values): Rename "info directories" to "show directories".
3885 * values.c: Rename convenience_info to show_convenience.
3886 (_initialize_values): Rename "info convenience" to "show convenience".
3888 * copying.awk (_initialize_copying): Rename "info copying" to
3889 "show copying" and "info warranty" to "show warranty".
3890 Rename {copying,warranty}_info to show_{copying,warranty}.
3892 * symfile.c: Rename add_syms_command to add_symbol_file_command.
3893 (_initialize_symfile, add_syms_addr_command):
3894 Rename add-syms to add-symbol-file.
3896 Thu Apr 18 18:08:30 1991 John Gilmore (gnu at cygint.cygnus.com)
3898 * symfile.h (free_named_symtabs): Rename from free_named_symtab.
3899 * symfile.c (clear_symtab_users_once, cashier_psymtab,
3900 free_named_symtabs): Move these routines from symmisc.c.
3901 * symmisc.c (same): same.
3902 (free_symtab): Make non-static.
3903 * symtab.h (free_symtab): Declare as exported void fn now.
3904 * dbxread.c (end_symtab, end_psymtab): Change comments.
3905 (initialize_dbxread): Call dbx_new_init() in case the first
3906 command is add-symbols.
3907 * target.c (dummy_target): Permit add_syms_addr_command.
3909 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3911 Permit symbols to be superseded when new symbol files have
3912 been read in, particularly for VxWorks.
3914 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
3915 to the main file, as well as to include files. Also, put global
3916 functions into the global psymtab, to make "i fun" work.
3917 (end_psymtab): Free named symtabs and psymtabs for a file, once a
3918 new psymtab for it has been read.
3919 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
3920 a file, once a new symtab has been read for it.
3921 * mipsread.c: FIXME. We need to do the same for MIPS, but it
3922 looks harder to determine the top-level block before it's been
3923 queued to the psymtab list.
3925 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
3926 If we have wiped out any old symbol tables, clean up at end of
3928 (symbol_file_command): Don't reference symfile_fns if it's zero.
3930 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
3931 defines for the blocks of a blockvector that contain global and
3932 file-static symbols and the first of the smaller scope contours.
3933 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
3934 decode_line_1, make_symbol_completion_list): Use the above.
3935 * coffread.c (end_symtab, patch_opaque_types): Ditto.
3936 * dbxread.c (end_symtab): Ditto.
3937 * expread.y (block): Ditto.
3938 * mipsread.c (throughout): Ditto.
3939 * symmisc.c (free_named_symtabs): Ditto.
3941 * symtab.c (list_symbols): Process the first symbol of the
3942 static psymbols list.
3943 (types_info): Restore this function from its untimely #if 0.
3944 It's not perfect, but it is better than nothing.
3945 (_initialize_symtab): Restore "info types".
3947 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3949 * m68k-stub.c: Remote stub for 680x0's, created from
3950 rem-m68k.shar (which is removed).
3951 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
3952 Remove RCS log stuff now that we use CVS and it blows our diffs.
3954 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
3956 * symmisc.c (free_named_symtab): Make it work, in its current
3957 kludgy fashion. Change result to indicate if we blew away bkpts.
3958 * dbxread.c (end_symtab): Accumulate result from
3959 free_named_symtab and print warning if we blew user's state.
3960 * symfile.h: free_named_symtab now returns an int.
3962 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
3964 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
3965 is the first symbol read, even if not mainline.
3966 (dbx_psymtab_to_symtab): symfile might be zero, cope.
3967 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
3968 (set_section_command): New command ("section xxx yyy" -- should
3969 be renamed to "set section xxx yyy" FIXME) which sets the
3970 base address of a section of the exec file, overriding the
3971 virtual address that BFD reports.
3973 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
3975 * exec.c: Add add_syms_addr_command to exec_ops, so you can
3976 load symbols at any address while examining an exec file.
3978 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3980 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
3981 for printing the float info is host-dependent, not
3982 target-dependent. FIXME.
3983 * i386-pinsn.c: Move #includes to top, remove useless ones.
3984 * i386-tdep.c: Don't bother including <.../reg.h> since we
3985 don't use it (and it doesn't exist on host systems).
3987 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
3988 Convert negative numbers properly.
3989 (ieee_test): Make numbers really random; fix format arg.
3991 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
3992 * core.c (core_detach): Unpush core_ops, which might not be on
3993 top. We used to just pop the top, which broke things. Don't
3994 need dont_repeat() any more.
3995 (core_file_command): Psst! Don't repeat it.
3996 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
3997 * expprint.c (print_subexp): Avoid switch fallthru on
3998 BINOP_ASSIGN_MODIFY, so we can print += and such.
3999 * frame.h: Fix typo.
4000 * inflow.c (kill_command): After killing inferior, print our
4001 current frame in the core file, if we have one.
4002 (generic_mourn_inferior): When inferior dies, either select
4003 the current frame (in the new target, e.g. core file), or
4004 set both the current and selected frames to NULL.
4006 Changes from Peter Schauer.
4008 * infptrace.c: Avoid <sys/ptrace.h> on USG.
4010 * Make all file names fit in 14 characters (sigh and damn!):
4011 mv hp300hpux-xdep.c hp300ux-xdep.c
4012 mv symmetry-xdep.c symm-xdep.c
4013 mv symmetry-tdep.c symm-tdep.c
4014 mv convex-opcode.h convx-opcode.h
4015 mv tm-vxworks960.h tm-vx960.h
4016 mv tm-vxworks68.h tm-vx68.h
4017 mv Makefile.srcdir Makefile.sdir
4018 mv gdb-int.texinfo gdbint.texinfo
4019 mv remote-sa.m68k.shar rem-m68k.shar
4020 mv remote-multi.shar rem-multi.shar
4021 * Makefile.dist, README, config.gdb, convex-pinsn.c,
4022 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
4023 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
4026 * command.c (user_info_1, user_info): New command for listing
4027 the user-defined commands.
4029 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
4031 * dbxread.c (really_free_pendings): Clear file_symbols
4032 and global_symbols after freeing them; otherwise, running
4033 this function twice (if it appears twice on the cleanup
4034 chain), we try to free things twice.
4036 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
4037 based on text_addr (the address of text in core), not on addr (the
4038 offset between text in the .o file and in core). This change
4039 is from Peter Schauer.
4041 * main.c: Define ALL_CLEANUPS as a cast of zero.
4042 (return_to_top_level): Use it.
4043 (main): Do all cleanups after each command run as part
4044 of the gdb startup sequence. Also do all cleanups before
4045 entering the command loop, and every time we exit the command
4046 loop and reenter. Before, the cleanups from the startup sequence
4047 were being left undone until the first error!
4048 (command_loop): Rename do_nothing cleanup to command_loop_marker
4049 so we can see it easily when examining the cleanup chain.
4050 (init_signals): Add another do_nothing for signal handling.
4051 (quit_command): Only try to kill target if it has execution.
4052 Problems in the target stack got us into a state where
4053 inferior_pid was nonzero but none of the targets had execution.
4054 In this state you couldn't exit gdb.
4056 * dbxread.c: Two changes from Peter Schauer.
4057 (echo_command): Fflush output after an echo command.
4058 (show_history): Pass all args to cmd_show_list.
4060 * utils.c (init_malloc): Call mtrace to turn on tracing
4061 if the environment variable MALLOC_TRACE is set to a file name.
4062 * mtrace.c: Add source file which provides a log of every malloc,
4063 free, and realloc to a trace file.
4064 * mtrace.awk: Add source file which analyzes the trace file.
4065 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
4066 (VERSION): Roll to 3.94.3.
4068 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
4069 (check_duplicates): Don't bother with watchpoints.
4070 (set_raw_breakpoint): Comment about danger of this routine.
4071 (watch_command): Parse and eval all args before calling
4074 * solib.c (find_solib): Avoid error in referencing memory to
4075 see if any more shared libraries have been added. This is
4076 particularly useful if the target has terminated. Bug reported
4079 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
4080 in bringing up 3.94.2 on the Sun-3.
4082 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
4083 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
4084 expression (in scope) before reenabling watchpoint.
4085 * signame.c (init_sigs): Add missing declaration of i, fix
4086 sys_siglist declaration.
4087 * source.c (list_command): Fixed range computation to use
4089 * stack.c (backtrace_command): Do not allow command if target has
4090 no stack, print informative error message.
4091 * target.c (target_command): Do not write into command line
4092 because this fails if the target command is used in a user defined
4093 command. [This change was enhanced by gnu to support any-
4094 unique-prefix matching on target names.]
4095 * valops.c (value_struct_elt): Avoid infinite loop on an
4096 erroneous attempt to print the member of function (try p main.p).
4098 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
4100 * expread.y (name_no_typename): Avoid reduce/reduce errors
4101 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
4102 Since the GDB parser really doesn't use name_no_typename in a
4103 name-only context, the parser can't tell the diff between
4104 names and numbers here. Avoid allowing a name_no_typename
4105 to be a NAME_OR_*INT to resolve the conflict.
4107 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
4109 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
4111 * valprint.c (val_print_fields): bitfield printing didn't handle
4112 byte order. Indirect through a few more fns to cope.
4114 * values.c (modify_field): also cope with byte order.
4116 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
4118 Cleanup for release 3.94.2:
4120 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
4121 include files. Roll version to 3.94.2.
4123 * coffread.c (init_stringtab): Read length into unsigned char
4124 array before swapping; don't assume 32-bit longs.
4126 * target.c (target_info): Don't bother with get_sym_file, just use
4127 the symfile global variable.
4128 * symtab.h, symfile.c (get_sym_file): Delete it.
4130 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
4131 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
4132 (read_type): Replace one more error() with complain().
4134 * mipsread.c (parse_partial_symbols): Replace printf with complain.
4136 * i960-tdep.c: Fix copyright attribution.
4138 * config.gdb: Quote all backquotes in doublequotes. You can
4139 quote me on that. BSD 4.4 shell found this one.
4141 * infptrace.c (throughout): The third argument to ptrace is an
4144 * infrun.c (wait_for_inferior): When program has terminated, we
4145 have to call target_terminal_ours before we pop that target off
4146 the stack (e.g. before a call to target_kill or
4147 target_mourn_inferior). This fixes problem where a program
4148 terminates, then GDB stops for (tty output) and you have to type
4149 "fg" to the shell to resume it. FIXME: This code for what to
4150 do after termination really should be in normal_stop instead.
4152 * gdbcore.h (read_memory_check): Change declaration; it changed
4155 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
4156 4.4 prereleases, this avoids a bug in their sgtty compatability
4158 * remote.c: Use terminal.h rather than hand-rolling the same.
4160 * signame.c, signame.h (psignal): Arg is unsigned, not int.
4161 * utils.c (strsave, strstr): Fix arg types.
4162 * valprint.c (val_print): lint
4164 MIPS symbol table support from Per Bothner:
4166 * symfile.c (symtab_fns): Remove initializer table that needs to
4167 be hacked for each new symbol file format supported.
4168 (add_symtab_fns): New function, chains symbol table
4169 handlers into the global list.
4170 (symfile_init): Search this list.
4171 * symfile.h: Add next pointer, declare add_symtab_fns.
4172 * coffread.c (_initialize_coffread): Call add_symtab_fns.
4173 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
4175 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
4176 symbol *). Thus, we no longer need the hack to trash
4177 pst->filename. Good, since that hack confused code in symfile.c!
4179 (reorder_symtabs, destroy_all_symtabs): Removed static
4180 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
4181 Instead, the latter now uses a temporary array (stack-allocated
4182 from an obstack, and then freed).
4184 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
4185 haven't been set in the outermost stBlock of a procedure. This was
4186 a problem with f77 binaries on Ultrix 4.?.
4188 (new_symtab, new_symbol, new_type): Continue changing code to use
4189 obstacks more and otherwise conform to dbxread internal style.
4190 Made the free_code of symtabs be free_linetable (as in dbxread)
4191 instead of free_contents. This implies memory leaks when reading
4192 a new symbol table, until the conversion is finished. Did change
4193 (struct symbol) and (struct type) to be allocated on the
4194 symbol_obstack. Blocks and blockvectors are among the things
4197 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
4198 tested much, but it solved one problem (reported by Meissner), and
4199 cleans up some other things. The problem happened when an
4200 included file contains actual code (functions) and not just
4201 definitions. The mips coff is a little inconvenient there, since
4202 it may cause a procedure to be mapped to the wrong psymtab.
4204 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
4205 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
4206 this will need work for the new core paradigm.
4208 Opcode patches from the net:
4210 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
4211 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
4212 missing altogether - they are added here. From Bruce Bauman.
4213 * mips-opcode.h: The low mask for C0 instructions was too small.
4214 From Garrett Lau. I modified the fix to check the entire 32-bit
4217 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
4220 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
4222 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
4224 * dbxread.c (read_type): Pointer subtraction (value_sub in
4225 valarith.c) sometimes failed because the types of the
4226 pointers being subtracted were not identical.
4227 These differed because dbxread.c was allocating pointer types
4228 using dbx_alloc_type+smash_to_pointer_type instead of
4229 lookup_pointer_type. I failed to find a justification for the
4230 former, so I changed it to use the latter. Similarly, I
4231 replaced smash_to_function_type by lookup_function_type,
4232 and smash_to_reference_type by lookup_reference_type.
4234 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
4235 _initialize_mipsread): corresponding changes.
4237 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
4239 * source.c (mod_path): Do tilde_expand on each component of the path,
4240 rather than on the (list of) paths as a whole.
4241 (print_source_lines): Set first_line_listed in addition to
4242 current_source_symtab and current_source_line. If the source was
4243 not findable, after a "dir" command to fix the problem,
4244 a "list" would get the wrong lines.
4246 While I was there... (gnu):
4248 * dbxread.c (read_type): Change error to complaint.
4250 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
4252 First attempt at detailed understanding of symbol table memory alloc.
4254 * dbxread.c (dbx_symfile_read): Free our string table if we
4255 aren't the mainline. Free the "info" struct since we're done with
4257 (init_psymbol_list): Free any previously allocated psymbol lists.
4258 (): FIXME: Should realloc-down the psymbol lists when done reading
4259 the main symbol file?
4261 * symmisc.c (free_symtab): Free fullname field too.
4263 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
4264 (REGISTER_ADDR): Make result type unsigned int.
4266 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
4267 define REGEX must also define REGEX1 (its dependency).
4269 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
4271 * tconfig/i960: No longer works, points you at vxworks960 or
4274 * xgdb.c, XGDB-README: Remove file. Users can get the much
4276 * Makefile.dist: Remove all trace of xgdb.
4278 * breakpoint.c (breakpoint_1): Pass demangle arg to
4279 print_address_symbolic.
4280 (clear_breakpoints): Remove unused function.
4281 (breakpoint_re_set_one): Guts of breakpoint_re_set.
4282 (breakpoint_re_set): Use catch_errors to do them all anyway.
4284 * gdb-int.texinfo (Host versus Target): Add section on what is
4285 a "host" feature versus what is a "target" feature.
4287 * infcmd.c (path_command, path_info): Handle the PATH variable
4288 (object search path) as conveniently as the source search path.
4289 * environ.c (set_in_environ): Set some vars in GDB's environment,
4290 in addition to the child's. PATH, G960BASE, G960BIN for starters.
4291 * source.c (mod_path): New function, from guts of
4292 directory_command, modifies a path. Used by path_command.
4293 (directory_command): Call it.
4294 * defs.h (strsave): Declare.
4296 * utils.c (sevenbit_strings): Add new printing option.
4297 (printchar): Use it.
4298 (strsave): Provide this handy helper routine.
4299 (set_width_command): Rename set_screen_width_command.
4300 (_initialize_utils): "set screen-width" => "set width";
4301 "set screen-height" => "set height"; add sevenbit-strings.
4303 * infcmd.c (do_registers_info): Print floating point registers
4304 in raw hex as well as float format, regardless of whether it is
4305 a "virtual" convertible register.
4306 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
4307 regs as a double, just in case it's being used that way.
4308 * values.c (unpack_long): Comment on array/function coercion.
4309 (unpack_double): Argument is in target byte order now. For
4310 integer arguments, just call unpack_long and float the result.
4311 * m68k-tdep.c: include defs.h for "const" handling.
4312 * remote-nindy.c: Use ieee-float stuff.
4313 (nindy_fetch_registers): Unpack double regs to host double, then
4315 (nindy_store_registers): Pack extendeds to host double, flip
4316 around by misusing unpack_double, send as target double.
4318 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
4319 zero, as when stopped at the first instruction of a process.
4321 * blockframe.c: Fix filename in comment (param.h => tm.h).
4322 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
4323 * tm-68k.h: Fix typos.
4325 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
4327 Changes from a bringup on the DEC Vax under Ultrix 4.0.
4329 * coredep.c (fetch_core_registers): Pass end-address of register
4330 section to register_addr as expected. Don't call supply_register
4331 if we'd just pass it garbage.
4333 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
4335 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
4337 * target.c (push_target, target_info): Cast enums to int for < or
4340 * stack.c (print_frame_info): Identify source file & line
4341 even if we can't print it.
4343 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
4345 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
4347 Clean up IEEE floating point support.

4355 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
4356 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
4357 double_to_ieee_extended.

4359 * m68k-tdep.c: Define ext_format_68881.
4360 * sparc-tdep.c: Define ext_format_sparc, though unused.
4361 * Makefile.dist (HFILES): Add ieee-float.h.
4362 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
4365 Obsolete the "coffstrip" program in favor of using BFD's strip.
4367 * nindy-share/coffstrip.c: Remove file.
4368 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
4369 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
4370 * tconfig/nindy960: Remove reference to coffstrip.o.
4372 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
4374 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
4376 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
4377 * dbxread.c: Remove static symfile_bfd.
4378 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
4380 * inftarg.c (child_detach): Pop the child_ops vector if the
4381 detach is successful.
4382 * remote-nindy.c (nindy_create_inferior): Don't push a new
4383 nindy_ops since nindy uses the same one for execution and memory
4385 * core.c (core_ops): Use child_attach and child_create_inferior
4386 rather than default attach and create_inferior functions.
4388 Handle floating point registers in core files.
4390 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
4391 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
4392 This version untested since BFD doesn't yet support sun3 core
4394 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
4395 conventions. Fix comments and style. This version has not
4396 been compiled yet, since we have no HP inhouse.
4397 * core.c (get_core_registers): Look for two sections, ".reg"
4398 and ".reg2", and pass both to fetch_core_registers sequentially.
4400 Revise directory path yet again.
4402 * source.c (forget_cached_source_info): Not static any more.
4403 (init_source_path): New default source path is "$cdir:$cwd".
4404 (dir_command): Handle variable arguments ($cdir, $cwd).
4405 (source_info): Print "Compilation directory" rather than
4406 "Originally compiled in" to remind people of $cdir.
4407 (openp): If the path contains $cwd, use current directory.
4408 (open_source_file): If compilation directory is known, replace
4409 first $cdir in path with the compilation directory.
4410 (print_source_lines): Even if we can't print the lines, set the
4411 current symtab and line for future commands like "info source" or
4412 "breakpoint". Also, error message now contains the file name,
4413 line number, and file access error message.
4414 (_initialize_source): Fix help text to describe changes.
4415 * main.c (cd_command): Forget cached source info when we chdir.
4416 * utils.c (strstr): Add simple implementation.
4418 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
4420 * coffread.c (read_one_sym, init_linetable, init_stringtab):
4421 Byte-swap COFF symbol tables if necessary when reading them in.
4422 Use complain() to replace error message in one spot. Needs
4423 corresponding change in bfd/coff-code.h to make some symbol
4424 swapping routines non-static.
4426 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
4428 Merge changes from Eirik Fuller, for UTek.

4431 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
4432 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
4433 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
4434 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
4435 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
4436 declarations of errno.
4438 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
4440 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
4441 <rpc/rpc.h> and <rpc/types.h>.
4443 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
4445 * i960-tdep.c (examine_prologue): Add new argument limit,
4446 which stops the scan at the end of the prologue, or at the PC.
4447 This fixes a problem where it walks down into the code for the
4448 user's statements if that code looks like function prologues.
4449 Mark Fox and I have been bouncing this code back and forth, making
4450 small changes to it. Callers changed to match.
4452 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
4454 Cleanup for gdb-3.94 release final:
4456 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
4457 the .c files from vx-share and nindy-share, from the various
4458 macros, since they are not found via ALLDEPFILES.
4459 (SFILES): Add tm-i960.h.
4460 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
4461 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
4463 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
4464 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
4466 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
4468 * am29k-tdep.c: Add contribution line.
4469 (examine_prologue): Cache information about function prologues in
4470 the misc-function-vector to avoid lots of references over the
4471 serial line while examining instructions.
4473 * core.c (core_close): New function made from cleanup_core.
4475 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
4476 remote-vx.c, remote.c, target.c, target.h,
4477 Update target_ops vector to add attach, close, and load entries.
4478 Use add_syms_addr_command, not add_file_addr_command, for
4479 add_file. Break out close routine from existing code.
4481 * dbxread.c (really_free_pendings): Don't free pending_blocks;
4482 they are in an obstack.
4483 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
4485 (define_symbol): Add symbol type parameter; change callers;
4486 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
4487 it to influence the symbol class on the i960.
4488 (define_symbol): Swap LOC_CONST's into target byte order.
4490 * exec.c (exec_close): New function.
4491 (exec_file_command): Call it.
4493 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
4494 Fix byte order of frame pointer.
4495 (read_var_value): Result of 0 if var's value can't be found,
4496 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
4497 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
4498 (locate_var_value): Use read_var_value and use its lazy address
4499 as the location of the var's value. Lint.
4501 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
4504 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
4505 obsolete Intel versions in favor of vxgdb versions.
4506 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
4507 code dealing with byte order of values, which Intel did in host byte
4508 order rather than gdb-4's target byte order.
4509 (i960_frame_chain_valid): Move to nindy-tdep.c.
4510 (examine_prologue, skip_prologue, frame_find_saved_regs,
4511 frame_args_address, leafproc_return, saved_pc_after_call,
4512 pop_frame): Add vxgdb versions from Mark Fox.
4513 (examine_prologue, frame_struct_result_address): Add code
4514 to deal with the saved value of G13 (struct return address
4516 (frame_args_address): Modify Mark's version to prefer the
4517 saved value over the current value in the topmost frame.
4518 Cache result in the frame info to avoid performance hair in
4520 (print_fault): Add gdb960 code for printing faults.
4521 (_initialize_i960): Actually call check_host.
4523 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
4524 add stub routines. FIXME, these currently just return zero!
4526 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
4527 (attach_command): Call target_attach, not target_open, now.
4529 * infrun.c (normal_stop): Make global, not static, for vx_attach.
4530 (child_attach): Rename from child_open.
4531 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
4532 don't confuse it with a zero step_resume_break_address.
4534 * inftarg.c (child_detach): Eliminate inferior_pid test.
4535 (child_files_info): Clean up message a bit.
4536 (child_ops): Use child_attach, not child_open, to attach.
4538 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
4539 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
4540 findvar.c to here, since it depends on the contents of the
4541 shadow_contents of breakpoints, but keep if #if 0 since it is
4544 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
4547 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
4548 (ptype_command, display_command): Eliminate have_inferior_p and
4549 have_core_file_p in favor of target_has_stack or
4550 target_has_execution.
4551 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
4552 code for actually finding the values of arguments, though we still
4553 keep track of the maximum stack offset for use in printing unnamed
4554 arguments. Handle missing FRAME_ARGS_ADDRESS.
4556 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
4557 (struct nindy_regs): Define registers passed to/from nindy.
4558 (nindy_fetch_registers, nindy_store-registers): Translate between
4559 nindy and GDB formats for the registers.
4560 (dcache_init): Statically allocate the cache, since it was being
4561 allocated by a malloc that was never freed anyway.
4562 (nindy_create_inferior): Error, not core dump, if no exec file.
4563 (nindy_before_main_loop): Use target_load, not target_add_file.
4565 * remote-vx.c (net_load): Specify large timeout for load
4566 requests. Allow user to break out with INTERRUPT.
4567 (net_break): Remove useless code, clean up. Change callers.
4568 (parse-args, skip_white_space, find_white_space): Clean up arg
4569 parsing to cope with quoted strings.
4570 (net_wait, net_quit): Never call error, just return status.
4571 (vx_read_register, vx_write_register): Cleanup status checking.
4572 #ifdef the code based on which CPU we are using (960 or 68k),
4573 FIXME, this should be completely general but it isn't yet.
4574 (vx_xfer_memory, vx_resume): Cleanup status checking.
4575 (vx_run_files_info): Improve message.
4576 (vx_load_command): Renamed from vx_add_file_command. Allow load
4578 (net_ptrace): Remove unused routine.
4579 (vx_wait): Adopt code from vxgdb960 to cope with broken
4580 connections to target machine and prompt to disconnect. Remove
4581 debug printouts. Map some EVENT_'s to SIGnals.
4582 (add_symbol_stub, vx_open): Print names of object files we found,
4583 and "ok" if we read their symbols OK. Clarify output in general.
4584 (vx_attach, vx_detach, vx_kill): Add these commands.
4585 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
4586 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
4587 "info files" output, and create_inferior, since we already have
4590 * stack.c (frame_info): Replace Frame_unknown with 0.
4591 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
4592 (return_command): Pop until the PC matches as well as the FP,
4593 so it works even if the FP is shared with another function,
4594 as in "frameless" or "leaf" procedures.
4596 * symfile.c (load_command): renamed from add_file_target_command.
4597 (add_syms_addr_command): renamed from add_file_addr_command.
4598 (add_syms_command): Stub to call target_add_syms.
4599 (_initialize_symfile): Change command names and descriptions,
4600 add-file => add-syms, and load from alias to its own command.
4602 * target.c (kill_or_be_killed, maybe_kill_then_attach,
4603 maybe_kill_then_create_inferior): Default for attempts to start
4604 a process, if one is already running, is to ask about killing
4605 it and retry if yes.
4606 (upstack_create_inferior): #if-0 it, strata obsolete it.
4607 (push_target, unpush_target, pop_target): to_close() a target
4608 before unstacking it.
4609 (target_info): Renamed from target_files_info.
4610 (_initialize_targets): Rename "i files" as "i target", accessible
4613 * target.h: Improve comments about the target_ vectored routines.
4615 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
4616 Convert commenting style to standard GNU style.
4617 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
4618 (SKIP_PROLOGUE): No longer a no-op.
4619 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
4620 (*_REGNUM): Sort register numbers.
4621 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
4622 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
4623 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
4624 are now 10 byte extendeds, not 8 byte doubles.
4625 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
4626 for nindy versus vxworks targets. FIXME, this should possibly go
4627 in the target vector.
4628 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
4629 frame_saved_regs and arg pointer with each frame.
4630 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
4631 (FRAME_ARGS_ADDRESS): Use cached result.
4632 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
4633 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
4634 (PRINT_RAMDON_SIGNAL): Call print_fault.
4635 (POP_FRAME): Now works.
4637 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
4638 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
4639 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
4640 (ADDITIONAL_OPTION_HANDLER): use target_load, not
4643 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
4644 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
4646 * valarith.c (value_subscripted_rvalue): Avoid handling
4647 floats and doubles specially; it gave alignment errors. Lint.
4649 * valops.c (value_of_variable, value_of_this): Error if unknown
4652 * valprint.c (print_floating): Bcopy rather than pointer-deref,
4653 to avoid alignment problems.
4654 (value_print): Handle unknown value address.
4655 (cplus_val_print): Two args are ignored; remove them. Change caller.
4656 (val_print): Use unpack_long rather than pointer-deref.
4659 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
4660 to avoid alignment problems.
4661 (value_being_returned): Error if return value unknown.
4662 (set_return_value): Add bogosity warning, FIXME. *
4664 * TODO: A woman's work is never done.
4666 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
4667 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
4668 Add ieee-float.o to OBS.
4669 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
4670 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
4671 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
4673 Changes to generalize the VxWorks RPC protocol slightly, to handle
4674 i960 as well as 68000.
4676 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
4677 * vx-share/reg.h: Produce i960 regs #ifdef I80960
4678 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
4679 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
4680 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
4681 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
4682 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
4683 so they will move in target byte order rather than network
4684 byte order (happens to be the same).
4686 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
4688 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
4690 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
4693 Add contribution lines to various files, showing where they
4696 * breakpoint.c (break_insn, check_break_insn_size,
4697 read_memory_nobpt): Remove to mem-break.c.
4699 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
4702 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
4703 entry has bad register number. This change is not
4704 tested in this release, FIXME.
4706 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
4709 * value.h: Force value's contents field to be aligned to hold
4710 at least a double or a long long (if supported). This avoids
4711 doing bcopy's in and out of the contents field.
4713 (step_1): Avoid coredump under obscure circumstances when we
4716 * symtab.h (misc_info): Add field to misc function vector for
4717 any kind of cached information the target code desires. AMD
4718 29000 uses this to avoid repeating examine_function_prologue's.
4720 * coffread.c: Lint. Remove static symfile, read_section_header.
4721 core.c (have_core_file_p): Lint: remove.
4722 expprint.c (print_subexp): Lint.
4723 infptrace.c, valops.c, valprint.c: lint.
4725 Roll in changes from vxgdb-5.0.1:
4727 * symtab.h: Comment byte order of each address class. Add
4728 LOC_LOCAL_ARG for frame-relative args (960).
4729 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
4730 symtab.c, symmisc.c: ditto.
4732 * infrun.c (init_wait_for_inferior): Clear stop_signal.
4734 * remote.c (remote_resume): Error if resume with a signal.
4736 * symfile.c (prim_record_misc_function): Clear misc_info.
4737 (fill_in_vptr_fieldno): Check stub type of arg.
4739 * valops.c (value_cast): Avoid looking up names of types whose
4740 name we don't know, to prevent coredump. Sun CC produces typedef
4741 rtx and the name of *rtx is zero...
4743 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4745 Roll in changes from final AMD 29000 port (Tiemann).
4747 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
4748 for ../include/a.out.encap.h. This might not work now that BFD
4749 is separately compiled. Instead, BFD support for encap will have
4750 to translate machine type 29k into the right COFF_MAGIC.
4752 * infcmd.c: Remove references to inferior_pid that aren't used
4753 in actual ptrace calls; use target_has_execution, etc.
4754 (have_inferior_p): Remove function.
4755 (program_info): Print target info rather than "process number";
4756 avoid gratuitous messages unless from_tty.
4757 (run_stack_dummy, finish_command): Set proceed_to_finish.
4758 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
4759 main.c: Lint. Lose have_inferior_p().
4760 inferior.h (have_inferior_p): Remove, lint.
4761 (proceed_to_finish): Add flag to ask that all regs be saved
4762 by normal_stop, for the few commands that need it, speeding up
4763 serial I/O. Add comments to stop_registers.
4765 * remote-eb.c: Remove newline from breakpoint message we grep
4766 for. Never time out when running the user program.
4770 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
4772 Roll in changes from vxgdb-5.0.1:
4774 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
4775 symbol in its raw form, we are processing an unlinked ".o" file.
4776 See if the target environment has assigned it an address, using
4777 target_lookup_symbol (VxWorks does), and enter it into the symtab
4780 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
4781 68k versions for a simpler version that assumes zero FP at bottom.
4782 Fixes bug of truncated stack reports.
4784 * target.h (target_lookup_symbol): Define this routine's args
4785 and result, finally.
4787 * target.c (nosymbol): Default routine for target_lookup_symbol.
4788 (target_default): Default lookup_symbol and call_function too.
4789 (files_info): Only print has_all_memory warning if a non-dummy
4792 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
4793 vx_convert_from_virtual): If target does not have floating point,
4794 zero register "values", and avoid doing cross-net conversions.
4795 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
4796 (vx_open): Rearrange code that attaches to target and reads
4797 symbols for all loaded modules, to work if some of the modules
4798 are not accessible. Add symbol_stub() and add_symbol_stub()
4799 as callbacks from catch_errors(). Allow connect attempt to be
4800 interrupted painlessly with ^C (FIXME, there are still some bugs
4801 if the interrupt happens during symbol reading.). Print
4802 final message with puts_filtered, since symbol messages are
4807 * main.c (catch_errors): Only print errstring if non-null.
4808 (command_loop): Avoid an ioctl per command to test ISATTY.
4810 * remote-vx.c (net_load): make static; avoid sophomoric msg.
4811 (vx_xfer_memory): Return correct result!
4812 (vx_files_info): Indicate whether target has float or not.
4813 (vx_lookup_symbol): Complain, not error, if target gone.
4814 (vx_open): Print "Connected" msg before disabling immediate-quit.
4815 [FIXME: lookup_symbol and vx_open changes need testing.]
4817 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
4818 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
4819 contributor lines and update copyrights to 1991.
4821 Changes from an attempted H-PUX host port:
4823 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
4824 defines PT_ATTACH and PT_DETACH but not PT_KILL.
4825 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
4826 * remote-vx.c: include <sys/time.h> for HPUX.
4827 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
4828 "core_file_command" routine to BFD regime. May not work yet.
4830 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
4832 * xgdb.c: Replace X10 version with some VJ version.
4833 (FIXME: Its copyright assignment is not on record.)
4834 * xgdb.c: Update include files to X11R4 (Xaw crud).
4835 (xgdb_display_source, create_text_widget): fix call to
4836 get_filename_and_charpos. Rewack source window stuff for X11R4
4837 (gleaned from include files, and "nm's" of binary libraries, since
4838 I had no doc available).
4839 (append_selection, append_selection_word): Disable with FIXME
4840 since R4 changed interface here.
4841 (create_buttons): Add back the old set of buttons.
4842 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
4844 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
4845 Roll VERSION to 3.94 (not yet final though).
4847 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4849 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
4850 obstack_int_grow, obstack_int_grow_fast): Eliminate
4851 cast on left of assignment, which gives MIPS cc fits and is
4854 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
4855 F_ALIAS. Use printf, not fprintf, when not passing a file
4857 (compare_opcodes): Check that identical instructions have
4858 identical opcodes, complain otherwise.
4860 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
4861 was reported by Roland McGrath.
4862 (unimp): Only match if exactly zero instruction. (Roland)
4863 (branches and traps): Generate all variations of these
4864 instructions with macros, based on a single call that defines
4865 each condition name and its binary representation.
4866 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
4868 * valprint.c (val_print_fields): Take, and use, format parameter.
4869 This means that "p/x struct" again prints the elements in the
4870 desired format. Changed callers.
4872 * stack.c (frame_info): Use filtered output, and indicate wrap
4873 points. Remove kludgy formatting designed to avoid line wrap.
4875 * utils.c (wrap_here): If the line is already full (because
4876 we had printed a long indent or long wrapped string), do an
4877 immediate newline-and-indent.
4879 * m68k-pinsn.c (print_insn_arg): Bugfix from
4880 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
4881 instruction is incorrectly disassembled as bkpt #8.
4883 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
4884 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
4885 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
4886 and then will dump core (sometimes). I traced it back to an
4887 uninitialized symfile_name in psymtab_to_symtab.
4888 (const_vol_complaint): Add quotes to message.
4889 (define_symbol): Only believe line number if gcc_compiled.
4890 Avoid allocating symbol if we will not return it.
4892 Add target strata support so that newly established targets go
4893 into their right place in the target stack (e.g. a new exec file
4894 doesn't wipe out the ability to access the running process).
4896 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
4897 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
4898 and initialize it properly in all the targets.
4900 * target.h: Document strata. Change return type of push_target.
4902 * target.c (nomemory): new function for dummy memory access.
4903 (tcomplain): Rename complain, now also used in symfile.c.
4904 (push_target): Push targets within strata. New return value shows
4905 whether new target is on top of stack or not. Always keep dummy
4907 (target_files_info): Ignore dummy target.
4909 * core.c (core_open): Warn user, and skip accessing file, if the
4910 core target is not the topmost target in the stack.
4911 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
4914 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
4915 target_ops, it doesn't belong there since we have no regs there.
4916 Change name of target from machine => memory to clarify.
4918 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
4920 * Freeze version 3.93 for release.
4922 * Makefile.dist: Handle vx-share and nindy-share subdirs
4923 properly when building gdb.tar.Z.
4925 * symtab.c: lint; add no_symtab_msg to consolidate the messages
4926 printed in various places, so I could change just one copy.
4928 * dbxread.c, coffread.c: Change references to bfd->iostream
4929 to cast to FILE *, now that BFD avoids needing types defined
4930 in other header files.
4932 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
4934 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
4935 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
4936 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
4937 (actually gcc -Wall).
4939 * dbxread.c: Remove first_global_sym, last_global_sym, since
4940 they are never referenced.
4942 * defs.h (baud_rate): Declare.
4943 main.c: Define it, and add the -b option to set it.
4945 * gdb-int.texinfo: Add text on how to define a new host or target
4946 architecture, prompted by Per Bothner's questions about MIPS
4949 * gdb.texinfo: Document "complaints". Change doc of -q since
4950 gdb no longer prints the copyright and blurb if you specify a file
4951 name to be debugged (just like Emacs). Add doc for Nindy-specific
4952 command line flags for specifying target serial port and such.
4953 Update copyright to 1991.
4955 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
4956 has taken over for us the job of ripping up executable files. The
4957 crud caused Per Bothner's port to not compile.
4959 * infrun.c (normal_stop): Avoid printing "Program exited
4960 normally" if we are in batch mode. This allows a GDB which
4961 executes a program on a target system, to behave like a Unix
4962 command (input from stdin, output to stdout, no extraneous
4965 * main.c (main): Allow additional machine-dependent command line
4966 options to be specified with the ADDITIONAL_OPTIONS,
4967 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
4968 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
4969 processing to occur just before the main loop with
4970 BEFORE_MAIN_LOOP_HOOK.
4971 (main): If a "core file" argument is specified, and it is not a
4972 core file, try it as a process ID to attach.
4973 (symbol_completion_function): Attempt to cope with
4974 "show screen-" TAB, not very successfully. This needs more work,
4976 (batch_file): New function, returns whether we are reading
4977 commands from an interactive tty on stdin, or from somewhere else.
4978 Called by normal_stop since it doesn't get from_tty passed down
4979 to it like many commands do.
4981 * remote-nindy.c: Handle command line options for nindy
4983 (nindy_before_main_loop): Prompt user for tty name if they
4984 don't specify it before getting to the interactive command loop.
4986 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
4987 and -r command line options. Also add hook before main loop
4988 to make it easy to specify a tty.
4990 * TODO: More things to do, one done.
4992 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
4994 * dbxread.c: Make complaint() calls pass pointer, not struct.
4995 Add complaints about badly formatted C++ type information
4996 (const/volatile indicator, and parse errors resulting in
4997 error_type). Fix C++ virtual member fn comment.
4998 (read_struct_type): Avoid bumping pointer if we got a parse
4999 error; this prevents our walking beyond the end of a string.
5000 Terminate loop on null char as well as semicolon.
5001 (process_one_symbol): Fix the LBRAC fix so that it uses the
5002 last previous SLINE, FUN, or SO record's PC address. C++ debug
5003 symbols did not have SLINE records in a useful order compared
5004 to the LBRAC records.
5005 (define_symbol): Handle "catch" records.
5007 * symtab.c (check_stub_type): Added new complain
5008 `stub_noname_complain' and added a consistency check to
5009 keep the debugger from crashing when finishing from an
5010 exception frame. A real fix will be needed later.
5012 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
5014 * infcmd.c (attach_command): Make global.
5016 * Makefile.dist (REMOTE_OBS): Make these compile by default,
5017 but make them easy to comment out. Perhaps later they should
5018 be enabled by what CPU you configure for? FIXME.
5019 (VERSION): Roll to 3.93.
5020 (pinsn.o): Remove rule for obsolete file.
5021 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
5023 Run down a problem that manifested by printing the wrong function
5024 name in stack traces of read_ofile_symtab. Turned out that the
5025 problem was the SunOS 4.1.1 (and previous) C compiler outputs
5026 the LBRAC symbol with an address in the *data* segment, which
5027 blew our binary search through the blocks.
5029 * dbxread.c: Use the complain() facility consistently to bitch
5030 about problems in the symbol file we are reading.
5031 (finish_block): Add code to check the nesting of the blocks;
5032 complain and Procrust them to fit if wrong.
5033 (make_blockvector): Check the order of the blocks, complain
5034 [but don't cope] if wrong.
5035 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
5036 symbols to be sure their PC value is greater than the last SLINE
5037 (line number) symbol we've seen, complaining and adopting the
5038 SLINE PC value if wrong.
5040 * symfile.h (struct complaint, complaint_root, complain,
5041 clear_complaints): Add.
5042 * symfile.c (complain, complaint_root, clear_complaints): Add
5043 facility to deal with non-fatal complaints and to regularize their
5045 (symbol_file_add): Clear complaint counters to allow new complaints.
5046 (initialize_symfile): Add 'set complaints' and 'show complaints'.
5048 * dbxread.c (dbx_symfile_read): Remember the address and size
5049 of the string table for the main symbol file, so we won't read it
5051 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
5052 to avoid reading the string table yet again. Lint.
5053 (throughout): Improve filtered output, including word wrap.
5054 (read_range_type): Improve Bothner's fix to handle other types too.
5056 * utils.c: Improve line wrap implementation. Handle unlimited
5057 width by making chars_per_line unsigned.
5058 (puts_filtered): New, easy, function.
5060 * defs.h (puts_filtered): add.
5062 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
5063 call the identical sort_symtab_syms() in symfile.c instead.
5065 * expread.y: Suggest the `file' command rather than `symbol-file'.
5067 * command.h (enum var_types): Add zinteger for seroable
5069 * command.c (do_setshow_command): Handle var_zinteger. Restructure
5070 nested if's into a switch.
5072 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
5073 we did not stop because of a breakpoint (it must have been for
5074 some other reason, like a "stepi"), so don't print anything.
5076 * symtab.c: Include <sys/types.h> all the time. Now that BFD
5077 doesn't include <sys/types.h>, old SunOS's require it for
5080 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
5082 A test port of gdb-3.92.6 to the Sony NEWS.
5085 Don't normally link in remote- or vx stuff.
5086 Some of it doesn't compile, and it wastes space for 99% of the users.
5087 Remove reference to no-longer-used HAVE_VPRINTF.
5088 Fixed BFD_DEP typo to BFD_DIR.
5090 Fix cast in arg to bfd_h_getlong.
5091 Make char *prefix be const.
5092 Fix how certain range types are mapped into builtin unsigned int types.
5094 Remove 2 #includes. They cause errors (on Sony, at least),
5095 and aren't needed (they wern't in earlier versions).
5097 print_address_symbolic should never demangle labels
5098 (since it prints *assembler-level* labels).
5100 [This was superseded by the change to printcmd below.]
5103 Add some "volatile" return types to avoid warnings.
5104 If MISSING_VPRINTF add vprintf function and not just macro
5105 (since vprintf is used in printcmd.c).
5107 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
5108 (The latter isn't grokked by some PCC-based compilers.)
5110 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
5112 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
5113 * nindy-share/coffstrip.c
5114 Added some forward declarations (otherwise, gcc complains
5115 about implicit extern redefined as static).
5117 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
5119 Changes inspired by Per Bothner:
5120 * printcmd.c (print_address_symbolic): Take additional parameter
5121 specifying whether to demangle.
5122 (print_address): Pass in asm_demangle to control demangling.
5123 (print_address_demangle): New fn, takes explicit arg to control
5125 * utils.c: Add new vars demangle and asm_demangle, and let them
5127 (fputs_demangled): If !demangle, just print the argument.
5128 (fprint_symbol): If !demangle, just print raw symbol.
5129 * valprint.c (val_print): Call print_address_demangle rather than
5130 print_address, to cause demangling to depend on the global
5131 rather than assembler-level demangling setting.
5132 * WHATS.NEW, gdb.texinfo: Document.
5134 * main.c (show_command): Show all settings if no arg.
5135 (initialize_main): Make "info set" the same as naked "show".
5136 * command.c (cmd_show_list): Handle prefix commands in the
5137 list, and print the name of the setting as well as its English
5138 description and value.
5140 Allow gdb functions to specify where a line should wrap if it
5141 exceeds the size of a terminal line. Use it to make the output
5143 * utils.c (set_screen_width_command): New fn, mallocs a buffer
5144 of the right size when screen width changes.
5145 (set_screensize_command, screensize_info): Remove #if 0'd fns.
5146 (wrap_here): New fn, indicates a point in the output where we
5147 should wrap the line rather than just letting it overflow at a
5149 (fputs_filtered): Implement wrapping.
5150 (n_spaces): New fn, returns a pointer to N spaces.
5151 (print_spaces_filtered): Use n_spaces.
5152 * defs.h (n_spaces): Declare.
5153 * stack.c (print_frame_info): Wrap with 4-space indent after
5154 fn name and before filename and line number.
5155 * printcmd.c (print_frame_args): Wrap with 4-space indent
5156 before each argument name is printed.
5157 * valprint.c (value_print): Wrap with no indentation before
5159 (val_print_fields): Wrap with indentation relative to nesting
5160 level before each field name.
5161 (val_print): Wrap with nesting indentation before array elements.
5162 * command.c (do_setshow_command): Avoid extra newlines,
5163 wrap with 4-space indent around values printed, end with period.
5164 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
5166 * breakpoint.c (breakpoint_1): Implement addressprint for
5167 "info breakpoints" display. Change file name and line number
5168 format to " at file:nnn" rather than " (file line nnn)".
5169 * gdb.texinfo: Document.
5172 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
5174 Frozen for gdb-3.92.6 release.
5176 README, WHATS.NEW: Update for 3.92.6 release.
5178 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
5179 coffread.o from configs since it is now built by default.
5180 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
5181 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
5182 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
5183 from configs since it is now built by default.
5185 Makefile.dist: Update for release 3.92.6. Handle files that
5186 have been moved to ../include, ../getopt, or ../bfd. Add
5187 saber.suppress and tests directory. Add config.status to
5188 the release (it will say "none").
5190 coredep.c: Minor formatting fixes.
5192 These changes were made in early December but only checked in now:
5193 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
5194 nindy-share/nindy.c: lint
5195 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
5196 register values coming back from the target; we store values
5197 in target byte order everywhere.
5199 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
5201 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
5203 * valprint.c (cplus_val_print, val_print_fields): New functions,
5204 which print C++ objects. They conspire to avoid printing a
5205 virtual base class more than once, following all the twists and
5206 turns of C++ virtual base rules.
5207 (val_print): Call the above rather than do it by hand.
5209 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
5210 symbol file, not for added files like shared libs. This really
5211 needs to be generalized to a timestamp per file.
5213 * core.c (cleanup_core): Avoid coredump if no core file.
5215 * config.gdb: Accept -host or -target in place of +host or
5218 * coffread.c (find_linenos): Avoid desupported BFD interface
5219 to line numbers. We still read them manually rather than using
5220 BFD's "generic" features.
5222 * gdbrc.tex, threecol.tex: Add GDB reference card and its
5224 Makefile.dist: Add refcard to OTHERS list for creating tar files.
5226 * Makefile.dist: Eliminate use of $< in explicit targets.
5228 * readline/Makefile: Use $< rather than $*.c, which does not
5229 include the VPATH in GNU Make.
5231 * tconfig/i960-bout, tconfig/i960-coff: These are identical
5232 copies of tconfig/i960, added for global configuration
5233 compatability. All i960 versions can read both coff and b.out.
5235 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
5236 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
5239 * TODO: Think of more things to do.
5241 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
5243 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
5244 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
5245 64-bit float conversion.
5247 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
5248 equivalent to sun?os4 so global config works.
5250 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
5252 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
5254 * main.c: Only declare linesize once; declare pagesize not at
5255 all, since it is never used.
5256 (main): Clear newly allocated line before it is used.
5258 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
5260 Further stabilization for the Intel 960.
5262 * Makefile.dist: Parameterize the location of the "include"
5263 and "bfd" directories, as well as "getopt". Add symfile.c.
5264 Link in both dbxread and coffread. Fix up "make depend" to
5265 rewack the locations of include, bfd, and getopt in its output.
5267 * README: Document moving include files, improve some of
5270 * coffread.c: Move common code out to symfile.c. Change
5271 symbol_file_command style interface to use new *_symfile_init
5272 and *_symfile_read interface under BFD. Use BFD internal
5273 info to locate line table, symbols, etc.
5275 * core.c (core_fetch_registers): Rename to get_core_registers
5276 to avoid confusion with fetch_core_registers.
5277 (register_addr): Move to coredep.c, which is already machine
5278 dependent. This leaves core.c pretty clean of dependencies.
5280 * coredep.c (register_addr): Accept this routine from core.c.
5282 * dbxread.c: Move common code (with coffread.c, etc) into new
5283 symfile.c. Each psymtab now contains a pointer to the
5284 format-dependent function that knows how to read it in. Make
5286 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
5287 (process_one_symbol): Add code to complain about a "compiler bug
5288 we muzzle here", if we actually see it.
5290 * eval.c (evaluate_subexp): Insert missing "break" statements
5291 in code that determines whether a variable is an lvalue in
5292 memory, register, or whatever. I detected this via a compiler
5293 bug in which it *almost* mashed out the whole switch statement.
5295 * gdb-int.texinfo: Add minor sections on configuring gdb for
5296 release, and about the README file.
5298 * infcmd.c (registers_info): Fix formatting somewhat. Still
5299 not as pretty as before, but it handles byte swapping.
5301 * remote-nindy.c: If data cache routines are interrupted while
5302 waiting for the remote end, be sure that any uninitialized cache
5303 blocks are on the free list, not on the valid list!
5305 * symfile.h: Flesh out this header file with all the various
5306 routines and variables that have been merged in from dbxread.c
5307 coffread.c, and symtab.c to symfile.c.
5309 * symfile.c: New file, containing code common to dbxread.c,
5310 coffread.c, and some code from symtab.c. All generic code for
5311 reading symbol files should be in here now.
5312 (unrecord_misc_function): Remove unused function.
5314 * symtab.h: Remove file-reading things to symfile.h.
5316 * symtab.c: Remove file-reading things to symfile.c.
5318 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
5319 to decode i960 fault types.
5321 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
5322 target.c: Change type of the "resume" function from int to void,
5323 since its result was never used.
5325 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
5327 * main.c: Replace "stupid" with "caution"; you now "set caution
5330 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
5332 * infcmd.c (do_registers_info): Call val_print to deal with the
5333 byte order of the registers being printed. FIXME, this makes
5334 the formatting of the output uglier.
5336 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
5337 defined, call it for signals the debugger doesn't itself use.
5338 The i960 uses this for more detailed fault information.
5340 * remote.c (remote_open): If arg is null, print help rather than
5343 * sparc-xdep.c (register_valid): Avoid declaring size, since
5344 various modules will think of various sizes depending on the
5345 architecture of their tm-file. FIXME, we need protection against
5346 actually entering one of those modules, which would clobber
5347 storage if not for the target architecture compiled into gdb.
5349 * stack.c (up_command, down_command): Always print the frame
5351 (up_silently_command, down_silently_command): New commands
5354 * i960-pinsn.c (reg), i960-tdep.c: Lint.
5356 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
5357 more parameters than it used to.
5359 * findvar.c (registers): Increase slop to 256 bytes, which should
5360 protect us against even most RISC machines with large register
5362 (locate_var_value): Move declaration inside related ifdef.
5364 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
5365 throughout, to avoid throwing away buffered input from the board.
5366 (nindy_wait): Supply_register takes addr_of_value, not value.
5367 (i960_print_fault): Renamed from i80960_fault.
5368 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
5369 (nindy_store_registers): Avoid regs_changed stuff, just stuff
5371 (nindy_create_inferior): Don't bother to write PC_REGNUM since
5372 we can set the PC in the call to proceed(). Unpush nindy_ops
5373 before pushing it on top, to avoid message to user. Eliminate
5374 commentary from Unix machines that just misleads here.
5375 (reset_command): Fix error message to suggest target command.
5377 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
5379 Release 3.92.5 as frozen.
5381 Stabilize the merged release...with help from lint, Saber C,
5384 Everywhere: Add include files needed to declare return types
5385 of functions called.
5387 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
5389 * breakpoint.h: Add undeclared breakpoint functions, and some
5390 functions for display handling since I couldn't think of a better
5393 * breakpoint.c (insert_breakpoints): Make code for disabling
5394 shared library bkpts more likely to work. It's used when we
5395 rerun a program and stop before the shared library has been
5397 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
5398 cast from pointer, so it squeezes through catch_errors.
5399 (bpstat_stop_status): Fix logic broken some time ago. We now
5400 always create a bpstat if the stop address matches a breakpoint,
5401 even if we don't stop there -- just like the old code used to do
5402 before I got my fingers into it (sigh).
5403 (breakpoint_1): Print "ignore count" after "stop only if"
5404 condition, since that's how it actually works.
5405 (mention): Handle watchpoints as well as breakpoints.
5406 (watch_command): use set_raw_breakpoint and mention to do most
5407 of the work (and initialize all the fields!). Only pass one
5408 arg to parse_c_expression, since that's all it takes.
5410 * command.c (not_just_help_class_command): Rename arg to args
5411 since we ignore "unused argument" warnings on vars named "args".
5412 inflow.c (child_terminal_info): ditto.
5413 infptrace.c (kill_inferior): ditto
5414 main.c (catch_errors, version_info, quit_command, pwd_command,
5415 source_command, dump_me_command, editing_info,
5416 set_history_size_command, set_history, show_history,
5418 stack.c (locals_info): ditto
5419 target.c (target_files_info): ditto
5420 valprint.c (set_input_radix, set_output_radix): ditto
5422 * core.c: Remove old variables for handling core and exec file
5423 sections (data_start, data_end, stack_start, stack_end,
5424 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
5425 text_end, exec_data_start, exec_data_end, text_offset,
5426 exec_data_offset, data_offset, stack_offset). They're
5427 superseded the more general build_section_table and
5429 (get_exec_file): Mention the `file' command.
5430 (read_memory_check): Rename to memory_error, and only call it
5431 in the case of an actual error.
5432 (read_memory, write_memory): call memory_error.
5433 (core_fetch_registers): Register section name is ".reg".
5435 coredep.c: Remove a bunch of crud now that all this file does
5436 is pull the registers out of a core file.
5437 (fetch_core_registers): Rewrite to actually work, I hope.
5439 dbxread.c: Use a.out.gnu.h, not system a.out, now.
5440 Replace index() with strchr(). Remove all the pre-BFD macro
5441 definitions for accessing the symbol file.
5442 (struct dbx_symfile_info): Encapsulate the information that
5443 dbx_symfile_init needs to pass to dbx_symfile_read in this
5446 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
5447 dbx_symfile_discard): Rearrange symbol file reading to divide
5448 the format-specific part from the format-independent part,
5449 leaving the format-independent part such as file name expansion
5450 and opening in symtab.c. This replaces
5451 partial_symbol_file_open and partial_symbol_file_read.
5452 Symbol_file_read, add_file, add_file_target_command,
5453 add_file_addr_command move to symtab.c. Pass an explicit
5454 "mainline" flag for when reading the main symbol table, rather
5455 than relying on the offset address to be zero or nonzero.
5457 (dbx_symfile_read): Don't allow void *'s to be printed as
5459 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
5460 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
5461 macro" debug version really work.
5462 (read_dbx_symtab): Remove unref'd parameter inclink.
5463 Avoid swapping N_SLINE symbols, for speed.
5464 Merge N_TEXT!N_EXT case with the other external symbol
5465 definitions' case. Add comments.
5466 (start_psymtab): Allocate the symfile name in the psymtab on
5467 the psymbol_obstack, rather than using the caller's storage.
5468 (end_psymtab): Only allocate a dependencies list if there are
5470 (psymtab_to_symtab_2): Use BFD when reopening file to read
5471 its symbols for real.
5472 (read_struct_type): Add FIXME comments where it needs work
5474 (read_huge_number): Add FIXME about overflows.
5475 (read_range_type): Add FIXME about comparing a long to 1<<32.
5477 * coffread.c: Minor changes to move things closer to the new
5478 regime with symtab.c and dbxread.c Major work is still needed
5481 * exec.c (exec_file_command): Remove old variables (see core.c
5483 (xfer_memory): If memory transfer is right at the end of a
5484 section, don't lose.
5486 * findvar.c (get_saved_register): If value is in a real
5487 register, LVAL is lval_register, not lval_memory.
5489 frame.h: Declare print_sel_frame and record_selected_frame.
5491 gdb-int.texinfo: New file, for GDB internals documentation.
5492 Very simple, unformatted doc of cleanups is there for now.
5494 gdbcore.h: Remove obsolete variables that described a.out
5495 section addresses and offsets. (See core.c above.)
5496 Declare fetch_core_registers and registers_fetched.
5498 getopt.c: Declare char *alloca(); even on SPARC.
5500 infcmd.c (run_command): Call target_kill rather than
5502 (step_command, next_command, stepi_command, nexti_command):
5503 Declare from_tty parameter even though we don't use it.
5504 (run_stack_dummy): argument BUFFER is a char array, not
5505 a pointer to REGISTER_TYPE.
5506 (finish_command): using_struct_return needed a value *,
5507 not a struct symbol *.
5509 * infptrace.c (child_xfer_memory): To avoid dependency on
5510 where sections are in memory, try PT_WRITE_D and if that fails,
5511 try PT_WRITE_I. Most Unixes don't care which you use.
5513 * infrun.c (step_resume_break_shadow): Change to array to
5514 match other breakpoint shadow storage.
5515 (clear_proceed_status): Pass address of bpstat to
5516 bpstat_clear, not the bpstat itself.
5517 (child_create_inferior): FIXME comment about if the child
5519 (start_inferior): Remove old function.
5520 (child_open): Use target_kill rather than kill_inferior.
5521 (wait_for_inferior): Ditto.
5522 (insert_step_breakpoint, remote_step_breakpoint): Use
5523 new step_resume_break_shadow.
5525 * inftarg.c (child_wait): If all child processes die,
5526 pretend that the one being waited for exited with signal 42.
5528 * main.c (command_line_input): When scanning for comments,
5529 don't coredump on unclosed quotes.
5530 (quit_command): Use target_kill rther than kill_inferior.
5531 (_initialize_main): Rename class_user from "user" to
5534 * printcmd.c (print_command_1): Initialize "fmt" if no format
5535 is specified by the user.
5536 (print_frame_args): Only add to args_printed if we are
5537 actually fetching args from the stack (avoiding undefined
5539 (_initialize_printcmd): Remove bogus \{ from string.
5541 * remote-eb.c (eb_open): Avoid coredump on no argument.
5543 * remote-nindy.c: Bring out of Intel environment into new
5544 target environment. Remove all conditional compilation on
5545 I80960. Massive hacking throughout.
5546 (nindy_xfer_inferior_memory): New routine stolen from
5548 (nindy_create_inferior): New routine pieced together, probably
5549 not quite working yet.
5550 (nindy_ops): New target_ops struct for nindy.
5552 * remote-vx.c: Use write_memory rather than target_write_memory
5553 to get error checking.
5554 (vx_add_file_command, vx_open): Use symbol_file_add rather than
5556 (vx_create_inferior): Use target_terminal_ours...
5558 * signame.c (_initialize_signame): Always initialize, since
5559 we need the table for things other than psignal.
5561 * solib.c (solib_add): Use symbol_file_add, not add_file.
5562 (solib_address): Return boolean result rather than struct
5563 pointer which nobody else knows the type of.
5565 * sparc-tdep.c, valops.c: Use write_memory rather than
5566 target_write_memory, to get error checking.
5568 * stack.c (locals_info, catch_info, args_info,
5569 get_selected_block, frame_command, up_command): Use
5570 target_has_stack, rather than have_inferior_p or
5573 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
5575 * symfile.h: New file, defining the interface between the
5576 generic and object-file-specific symbol reading code.
5578 * symtab.c: Move generic symbol-reading interface to symtab.c,
5579 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
5580 table to map BFD targets to symbol-reading modules in GDB.
5581 Change index to strchr.
5582 (lookup_struct_elt_type): Use error() rather than hand-made
5583 simulations thereof.
5584 (lookup_partial_symbol): Speedup slightly when length == 0.
5585 (symbol_file_add): New function.
5586 (symbol_file_command): Call it.
5587 (symfile_open, symfile_init): New function.
5588 (add_file_target_command, add_file_addr_command): moved from
5591 * target.c (target_command): use target_kill.
5593 * target.h (target_files_info): Don't declare, never called
5596 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
5597 files to determine stack end address.
5599 * valarith.c (value_x_binop, value_x_unop): Change error message
5600 to be more useful. Pass proper argument to value_struct_elt.
5602 * valops.c (value_assign): FIXME comment that long long
5603 bitfields will break here.
5605 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
5606 Update `make saber_gdb' to work better.
5608 * TODO: A woman's work is never done.
5610 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
5611 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
5612 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
5613 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
5614 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
5615 valops.c, valprint.c, exec.c: Lint.
5618 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
5620 Continuing Intel 960 port merge of GDB.
5622 * Makefile.dist: Merge i960 "nindy-share" files. Rename
5623 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
5624 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
5625 Wack over "make depend" so it handles files in subdirectories
5626 vx-share, nindy-share, bfd, and in the current directory.
5628 * blockframe.c (get_prev_frame_info): Remove fatal error
5629 if stack not defined.
5631 * core.c (core_open, core_detach): New functions that handle
5632 the old "core-file" command as "target core" and "detach" instead.
5633 (core_file_command): Call them.
5634 (core_xfer_memory): Use common routine xfer_memory.
5636 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
5637 dbxread now uses bfd for everything but symbol reading itself.
5638 BFD internals are used to drag out the relevant file offsets.
5639 (partial_symbol_file_open): Change args all around for BFD.
5641 * symtab.c: Rename "value" to "val" everywhere, so we can
5643 (symbol_file_command): New command, moved from dbxread.c
5644 and coffread.c. It uses BFD to read the file, then vectors
5645 based on its type, to dbx or coff symbol readers.
5646 * symtab.h: Extern a few vars for symbol_file_command.
5648 * target.h: Breakpoint takes a char * save area, not a char **.
5650 * valprint.c (val_print): When unpacking bitfields, offset
5651 the address in gdb of the value, if it is declared with a shorter
5652 type. Remove the last "runtime kludge test" of host byte order.
5654 * utils.c: Remove old my_bfd_read routine.
5656 * stack.c (frame_info): Use target_has_stack. Print program counter
5657 register's actual name rather than "pc", since it's called the
5658 "ip" (instruction pointer) on the i960 (sigh).
5660 * target.c (target_command): Add command for selecting a target
5661 type and calling its open routine. This is used for initiating
5662 communication with a particular target, in a generic way.
5664 * tm-i960.h: Update for modern gdb. Remove semicolons from
5665 various macros. Handle reading struct return convention, and
5666 error-out attempts to return structs with the "return" command.
5667 Be sure gdb doesn't think we know how to call functions in the
5670 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
5671 to i960_xxx in lower case.
5672 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
5673 not being defined yet.
5675 * remote.c (remote_open): Call start_remote to initialize
5676 wait_for_inferior during open.
5677 (remote_xfer_inferior_memory): Return length written rather
5680 * remote-vx.c (target_command -> vx_open): Use new generic
5682 * remote-eb.c, inftarg.c, exec.c: ditto.
5684 * infrun.c: Fix comments.
5685 (attach_program -> child_open): Use new generic target command.
5686 (wait_for_inferior): Clear saved register values before target_wait,
5687 so target_wait can set some of them if convenient.
5689 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
5690 Return success indicator, not void.
5691 (child_xfer_memory): Avoid fetching initial word if we'll
5692 overwrite it anyway.
5694 * infcmd.c (attach_command): Use new generic target open routine.
5695 (_initialize_infcmd): Update doc on attach and detach commands.
5696 (do_registers_info): Merge in a byte-order problem as a FIXME
5699 * findvar.c (find_saved_register): Avoid problem in current frame.
5700 (read_relative_register): Ditto.
5701 (write_register): Convert byte order on the way out.
5703 * exec.c (file_command): Add.
5704 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
5705 (xfer_memory): Common function between core_xfer_memory and
5707 (exec_xfer_memory): Use it.
5709 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
5711 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
5712 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
5713 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
5715 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
5717 Merge Intel 960 port of gdb, continuing...
5719 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
5720 symbol_file_command): Pass from_tty arg to hush 'em up.
5722 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
5723 Add magic numbers for 960 COFF format.
5725 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
5727 Merge Intel 960 port of gdb, from Intel "1.2" release.
5729 CHANGE_LOG entries from their port, which was based on
5732 Thu Sep 6 11:02:22 PDT 1990
5733 Remove temp file if download is interrupted.
5735 Wed Aug 1 09:08:33 PDT 1990
5736 Now uses binary protocol to talk to NINDY.
5737 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
5738 Times out after 5 seconds when trying to talk to NINDY.
5740 Tue May 29 12:54:49 PDT 1990
5741 Added variable baud rate (-b switch).
5742 Source code reorganization.
5744 Thu Apr 26 11:09:55 PDT 1990
5745 More cleanup of batch mode; specifically, execute "-s", "-e", and
5746 "-se" switches as soon as they are encountered on the invocation line.
5748 Fri Apr 20 13:47:15 PDT 1990
5751 Thu Apr 19 09:54:28 PDT 1990
5752 Add 'reset' command.
5754 Wed Apr 18 09:48:07 PDT 1990
5755 After opening remote tty, wait for 1 second to go by without input
5756 from it before trying to talk to NINDY (fixes problems with the
5757 Heurikon HK80/V960E).
5759 Mon Apr 4 16:33:05 PDT 1990
5760 Some output was not being suppressed in 'batch' mode.
5762 Thu Mar 22 15:31:11 PST 1990
5763 Ask user if old symbol table should be deleted when new file is
5766 Allow user to run a program downloaded before gdb960 was brought up.
5768 Correct "exec-file" help message for i80960 context.
5770 Correct bug in calculating user space address: could occasionally
5771 corrupt user program.
5773 Make sure to zero low-order bits in rip's because of bug in 960CA
5774 A-step part: could cause operation faults when "next"ing across
5777 Correct bug that made it impossible to get source line numbers for
5778 code loaded at addresses higher than 0x7fffffff.
5780 Wed Jan 10 12:43:22 PST 1990
5781 Open remote tty for exclusive use.
5783 Fri Jan 5 12:14:42 PST 1990
5784 Correct disassembly (CA manual was right after all):
5785 opcode for sysctl is 0x659
5787 Mon Oct 23 12:03:04 PDT 1989
5788 Use G960BASE and G960BIN environment variables to find 'sx' utility.
5790 Mon Oct 16 14:15:09 PDT 1989
5791 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
5793 Mon Oct 2 15:56:31 PDT 1989
5795 Added 960CA disassembly support.
5797 To simplify maintenance:
5798 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
5800 - eliminated opcode.h: incorporates tables into i960-pinsn.c
5801 - moved 960-specific routines from i960-pinsn.c to i960-md.c
5802 - made disassembly interface identical to that in gdmp960.
5806 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
5808 * target.h: Allow targets to stack. Add target_has_memory,
5809 _registers, etc. Restructure memory access and "info files"
5810 to walk the target stack.
5811 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
5812 target.c: Change tables to match target.h.
5813 * inflow.c (child_mourn_inferior): pop child_ops.
5814 (generic_mourn_inferior): Use new has_stack flag.
5815 * infptrace.c (child_xfer_memory): New memory regime.
5816 * inftarg.c (child_files_info): New "info files" regime.
5817 * remote-eb.c: New memory regime, new info files.
5818 * remote-vx.c: New memory regime, new info files. Now use
5819 separate targets for VxWorks attachment to machine, and
5820 actually running a process under VxWorks, since one has
5821 stack & execution & regs and the other doesn't.
5822 * remote.c: New memory regime, new info files.
5823 * sparc-xdep.c (fetch_core-registers): New memory regime.
5824 * target.c: New routines and support for stacked targets,
5825 new memory regime, new info files regime.
5828 Generalize section handling for an arbitrary number of sections,
5829 including use of the new BFD (binary file) library.
5830 * gdbcore.h: Add struct section_table.
5831 * exec.c (build_section_table): Iterate all sections and
5832 record what gdb needs to know about them.
5833 (exec_command): Use it.
5834 (exec_xfer_memory): Use the table.
5835 (exec_files_info): Print the table.
5836 * core.c (core_file_command, core_xfer_memory, core_files_info):
5838 * source.c (find_source_lines): Use bfd_get_mtime.
5839 * dbxread.c: Quick changes to make it compile with new BFD.
5840 * utils.c (error): Avoid using bfd_error in generic routines.
5842 * core.c (core_fetch_registers): Get from the ".regs" section of
5844 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
5846 * inferior.h (attach_flag): Export.
5847 * infcmd.c (run_command): use new target_create_inferior.
5848 * infrun.c (child_create_inferior): Don't return result.
5849 * Makefile.dist (VERSION): 3.91.4.
5851 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
5853 * breakpoint.c (bpstat_num): Handle breakpoints which have
5854 since been deleted, such as temporary breakpoints.
5855 infcmd.c (program_info): ditto.
5857 * core.c (core_file_command): Display the frame where the core
5862 * remote-vx.c (target_command): Merge in target command from
5863 targ-vx.c. A few other cleanups.
5865 * TODO, Projects: Lots more stuff to do...
5867 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
5869 Massive changes to wall off the remote-debugging interface
5870 behind a function vector. The port to handle VxWorks targets
5871 is also part of this.
5873 All files: Replace references to renamed functions,
5874 remove references to remote_debugging, remove references to
5875 have_include_file, have_core_file in favor of target_has_stack,
5876 target_has_memory, etc.
5878 * Modularize the breakpoint interface.
5879 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
5880 a breakpoint instruction.
5881 breakpoint.c: struct breakpoint's shadow_contents now sized as
5883 (insert_breakpoints): Vector to target to install breakpoints.
5884 (remove_breakpoints): Vector to target here too.
5885 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
5886 sparc-tdep.c (single_step): Use new breakpoint interface for
5887 the single-step breakpoints.
5888 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
5889 New file, contains routines to insert and remove breakpoints by
5890 reading out the old contents and later replacing them. This is
5891 how ptrace breakpoints work, and many remote systems as well.
5893 * tm-vxworks68.h: New config file, overrides a few things for
5894 Wind River's preferences.
5896 * target.h: New file, for transfer vector used to talk to the
5897 inferior (child, attached, core, exec, remote, etc). All accesses
5898 to the thing being debugged should come through these vectors.
5899 target.c: New file, routines to handle transfer vector.
5900 (various files): Add transfer vectors XXX_ops for the various
5901 targets and pseudo-targets (core files, etc) we support.
5903 * breakpoint.c (bpstat_stop_status): Further explorations of
5904 watchpoints and why things don't work all the time.
5905 (bpstat_alloc): New fn to allocate a bpstat and chain it.
5907 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
5908 the local gdbinit if it doesn't already have it.
5910 * core.c (core_ops): add and install.
5911 Allow core debugging without exec file.
5913 * dbxread.c (free_and_init_header_files): Merge two fns.
5914 (end_symtab): Free named symbol table when a new version comes in.
5915 (read_dbx_symtab): Relocate all kinds of symbols with base
5916 address. First step toward handling different text, data, bss
5918 (add_file_addr_command): Renamed add_file_command.
5919 (add_file_command): Vector to remote handler.
5920 Add "load" as an alias for "add-file" command.
5922 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
5923 non-returning functions.
5925 * exec.c: Add exec_ops, and push it as a target when an exec
5928 * infcmd.c (run_command): Pass executable file name and arg list
5929 separately when starting an inferior. Permit "run" when no exec
5930 file is specified, for VxWorks.
5931 (detach_command): Move to child_detach in inftarg.c.
5933 * inftarg.c: New file. Unix-child-specific routines, and the
5934 child_ops structure.
5936 * inferior.h (registers): Export "registers" as the way for
5937 target dependent register handlers to find gdb's local copy of
5938 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
5939 since it is now used by places that want wait_for_inferior to
5940 handle the grunge but want to see every trap from the inferior.
5942 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
5943 Eliminate remote_debugging hooks in terminal handling.
5945 * infrun.c: Replace start_inferior with child_create_inferior.
5946 Move all the hair of Unix shells and ptrace idiosyncracies into
5947 child_create_inferior, so remote handlers don't have to deal.
5948 Remove running_in_shell. Rename stop_after_attach to
5949 stop_soon_quietly, and use it in a few other places where we want
5950 to just call wait_for_inferior and get control back on the first
5951 trap. trap_expected now never takes a value > 1.
5952 (init_wait_for_inferior): Initialize static vars when a new
5955 main.c (gdbinit): Add new hook for .gdbinit file name, let
5956 it be overridden by config files as GDBINIT_FILENAME.
5957 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
5958 Both of these are used for VxWorks gdb.
5960 mcheck.c: rename include file "gmalloc.c" to avoid problems
5961 with system include file "malloc.c".
5963 param-no-tm.h: New include file, same as param.h but does not
5964 include the default "tm.h" file. This is used in files where
5965 the target is known, e.g. remote-eb.c or sparc-xdep.c.
5967 param.h: Now just a shell that includes tm.h and param-no-tm.h.
5969 remote-vx.c: New file, VxWorks remote debugging support. Uses
5970 RPC routines that are shared with the target system, in directory
5973 remote.c: Vectorize remote interface.
5975 source.c: Globalize source_path, and make an alias "l" for "list"
5976 since we now have the "load" command.
5978 sparc-xdep.c: Use new param-no-tm.h.
5980 symmisc.c (free_named_symtab): Add new function from Wind River.
5981 However, ifdef it out for now while we think about what it should
5984 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
5986 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
5987 non-Unix-children handle this with their own code in the target
5990 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
5991 source and target lists. Add vx-share to default list of include
5992 directories. Add new files to src and target lists: mem-break,
5993 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
5994 ${srcdir} versions of munch and createtags are used.
5996 * valops.c (find_function_addr): Split out of call_function.
5997 (call_function_by_hand): Rename call_function; this function
5998 calls functions in the target by laboriously patching the target
5999 word-by-word with the right stack, args, regs, etc.
6002 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
6004 Handle AMD 29000 a bit better.
6006 * remote-eb.c (readchar): Mask received char log to make it readable.
6007 (remote_start): Pass arguments down to executing program.
6008 Make startaddr unsigned.
6009 infrun.c (start_inferior): Accept args, pass them to
6011 infcmd.c (run_command): Pass args down to start_inferior.
6013 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
6014 the target object file format.
6015 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
6017 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
6018 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
6020 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
6022 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
6023 * TODO: We did a few things, we have more to do though.
6025 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
6026 * inflow.c (inferior_died): Clear deferred stores.
6028 * Debug problems with dummy frames and calls to the inferior.
6029 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
6030 * sparc-tdep.c (do_restore_insn): Simplify.
6031 (sparc_frame_find_saved_regs): Simplify and fix what we find.
6032 (sparc_push_dummy_frame): Simplify and fix what we push.
6033 (sparc_pop_frame): Slightly more hair here, deciding whether
6034 we are restoring a saved PC or returning to a return address in %i7.
6035 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
6037 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
6038 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
6039 * obstack.h (chunkfun): ditto.
6040 * defs.h (xmalloc, xrealloc): ditto
6042 * utils.c (quit): Grab the terminal from the child if necessary.
6044 * inflow.c (term_status_command): Rename to term_info, change
6047 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
6048 (is_delayed_branch): Speed up.
6049 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
6050 Still missing some float ops, and needs testing.
6052 * Support for input and output radixes other than base 10
6053 * defs.h (input_radix, output_radix): Declare.
6054 * expread.y (yyparse, parse_number): Handle changes of input
6055 radix, and ambiguous names-or-numbers in radixes >10.
6056 * printcmd.c (print_scalar_formatted): Print formatted hex
6057 numbers in varying column widths.
6058 * valprint.c (val_print): Use output_format to print scalar ints.
6059 (set_input_radix, set_output_radix, set_radix): Create.
6060 (set_output_radix): Set output_format from output_radix.
6061 (_initialize_valprint): add `set radix' but leave the others off.
6063 * main.c (execute_command): Let stupid questions be turned off.
6064 (_initialize_main): Handle "set stupidity", etc.
6066 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
6067 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
6069 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
6071 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
6072 bfd stuff is still screwed up, but with some manual work, it
6075 * breakpoint.c (bpstat_do_actions): Start over if a command
6076 proceeds the inferior, since the inferior will have stopped and
6077 will need to have its new stop-actions taken care of.
6079 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
6080 compiler fits, simplify it.
6082 * gdb.texinfo (directory command): Doc new dir command.
6083 source.c (directory_command): "dir" now puts things on the front
6084 of the path, moves dups up front, and handles multiple names
6085 on the command line, inserting each one in order. It also
6086 blows away cached line and full_filename info.
6088 * stack.c (backtrace_command): Skip "more stack frames follow"
6091 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
6092 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
6093 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
6094 The only odd one was Gould NP1, which had defined vprintf to
6097 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
6098 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
6099 variable, inspect_it.
6100 valprint.c (print_string, val_print): Use the global inspect_it
6101 to indicate whether to print in Epoch style or normal style.
6103 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
6105 * printcmd.c (call_command): add an alias for the "print" command
6106 which runs expressions and doesn't print the result if void.
6107 (print_command_1): implement it.
6109 * command.c: Remove #if 0'd code. Initialize all the fields
6110 in add_cmd (). Rename do_nothing_command to
6111 not_just_help_class_command, and make it externally visible.
6112 command.h: add user_commands to struct.
6113 * main.c (define_command): Don't overload c->function with a char
6114 string as well as a function pointer.
6116 * eval.c (evaluate_subexp): Reinstall tiemann changes to
6117 calling convention of value_struct_elt () that got dropped in
6120 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
6121 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
6123 * tm-sparc.h (POP_FRAME): replace some constants with defines.
6125 * sparc-xdep.c (store_inferior_registers): defer stores to regs
6126 until a good time (e.g. when we are about to run the child),
6127 saving ptrace calls.
6128 * infrun.c (proceed): handle DO_DEFERRED_STORES.
6129 * tm-sparc.h: define DO_DEFERRED_STORES.
6131 * sparc-xdep.c (store_inferior_registers): when storing float
6132 registers, don't store stack regs too. When storing the SP,
6133 however, DO store the stack regs too. This fixes a bug in which
6134 the dummy frame is not recognized when a call_function finishes,
6135 because its frame pointer (in the stack regs) was never
6137 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
6138 even though we don't know how to read them from an inferior.
6139 valops.c (call_function): Comment about storing SP.
6141 * infrun.c (save_inferior_status): Save away the original bpstat
6142 chain so it can be restored later. Install the copied version for
6143 use by whoever saved the status. It will be blow away by
6144 restore_inferior_status, and the original chain restored. This is
6145 important for people who have pointers into the original.
6147 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
6148 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
6149 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
6152 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
6154 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
6155 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
6156 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
6158 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
6160 * Merge Mike Tiemann's multiple inheritance changes from Sun.
6161 Store the baseclasses in a type struct starting from array element
6162 0 rather than from the unusual array element 1.
6164 dbxread.c: the above.
6165 (virtual_context): Add
6166 Read new debug information about which virtual function table
6167 a virtual function is from, and store it in fn_field.fcontext.
6169 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
6170 TYPE_FN_FIELD_STATIC_P.
6172 symtab.c: the above.
6173 valops.c: the above. Handle pointer casts of object *'s.
6174 (search_struct_method): Add.
6175 (value_struct_elt): First arg is now a pointer to a value, and is
6178 valprint.c: the above.
6179 values.c (value_virtual_fn_field): Add type arg. Handle
6180 offsetting to the proper object when calling virtual fns.
6182 (baseclass_addr): Add valuep arg.
6184 * README: Document the current state of BFD config (missing).
6185 * TODO, ChangeLog, Makefile.dist: Roll version.
6186 * WHATS.NEW: Add summary of changes since 3.5.
6188 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
6190 * dbxread.c (read_struct_type): Clear bit vectors whenever
6192 symtab.c (B_CLRALL): define.
6194 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
6195 using == rather than =. Huh... This fixes the dreaded problem
6196 wherein builtin_type_int becomes TYPE_CODE_FLT.
6198 * core.c (info_files): Show the inferior pid.
6200 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
6201 already knows how to look in the source directory.
6203 * Remove psymtab hair from many places. Remove duplicated code
6204 for searching symbol tables. Hide psymtabs from most places.
6205 Make it fast to get from a psymtab to its symtab.
6207 blockframe.c (blockvector_for_pc): Remove psymtab hair.
6208 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
6209 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
6210 dbxread.c: export psymtab_to_symtab, make it work if called N times.
6211 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
6212 new symtab completely. New psymtabs get symtab pointer
6213 initialized to zero. Remove MI warning printf.
6214 symtab.h: Comments. Add psymtab to symtab pointer.
6215 (PSYMTAB_TO_SYMTAB): New macro.
6216 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
6217 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
6219 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
6221 (print_frame_info): Avoid special-casing symbols that have not yet
6224 * source.c (open_source_file): Quick path if we have already
6225 located the source file by its full name.
6227 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
6228 find_pc_psymtab. When a name is found in the misc function
6229 vector, search the symbol table for its mangled name, not the
6230 name that the user typed.
6232 * bfd.h: Fix missing comment terminators, make #endifs match.
6234 * valarith.c (value_less): Handle unsigned int comparisons.
6235 Add FIXME about pointer compares, which assume host and target
6236 pointers are the same.
6238 * command.c (do_nothing_command): lint
6239 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
6240 fix comments on debug symbol format for visibility. Actually set
6241 visibility of symbols.
6242 main.c (echo_command): lint; use <readline/history.h>.
6243 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
6244 obstack.h (_obstack_blank): Rearrange pointer math to avoid
6245 pointing past end of allocated memory; saber complains.
6246 obstack.h: Declare the external functions that we use.
6247 valarith.h: use <string.h>
6248 solib.c (solib_add): lint.
6250 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
6252 * main.c (initialize_main): Default info_verbose to off, now that
6253 symbol reading is fast.
6254 (quit_command): Avoid clobbering exec_bfd while quitting.
6256 * Initial BFD (binary file diddling library) merger:
6257 coffread.c: Change AOUTHDR to struct exe_hdr.
6259 core.c: initialize initialized data at compile time.
6260 (core_file_command): Move from coredep.c, convert to bfd.
6261 (xfer_core_file): Convert to bfd.
6262 exec.c (exec_file_command): use bfd routines.
6264 mips-tdep.c: Remove exec_file_command and friends.
6267 * coredep.c: (fetch_core_registers) Convert core_file_command to
6268 fetch_core_registers.
6269 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
6271 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
6272 (my_bfd_read): More bogosity, which I don't think we call.
6273 (program_name): Remove this atrocity asap!
6275 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
6278 values.c: allocate_repeat_value was not clearing the
6279 optimized_out field.
6280 (value_static_field): minor stylistic fix (wrong macro was used).
6281 valops.c (value_struct_elt_for_address): didn't work for C++
6284 * signame.c (_initialize_signame): Initialize signal names once.
6286 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
6287 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
6288 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
6290 * remote-eb.c: Support user-settable baud rates on the serial port.
6292 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
6294 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
6296 * tconfig/sun3os4: Remove warning about native assembler,
6297 since it also occurs in the xconfig file.
6299 * findvar.c (registers): Allocate some slop after `registers'
6300 to prevent stray accesses from trashing the next variable.
6302 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
6303 on the sun-3, by changing the #ifdef from `sun3' (which is not
6304 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
6305 vars, which happened to follow `registers' in the executable.
6307 * readline/history.c (history_search): Heed gcc-2's advice
6308 and parenthesize && inside ||).
6310 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
6311 tm-29k.c: Insert FSF copyright headers.
6313 * remote-eb.c: Better comments.
6315 * Makefile.dist: Update to 3.91.6.
6316 * TODO: note PREPARE_TO_STORE problem.
6318 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
6320 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
6322 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
6324 * infrun.c (wait_for_inferior, at end): Don't set up
6325 prev_* if the inferior no longer exists.
6327 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
6328 CANNOT_EXECUTE_STACK.
6329 valops.c (call_function): Use it.
6331 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
6333 * inferior.h (PC_IN_CALL_DUMMY): New macro.
6334 infrun.c (wait_for_inferior, 2 places): Use it.
6336 * values.c (value_being_returned): Only use
6337 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
6339 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
6340 right thing for remote-eb.c.
6342 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
6343 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
6345 * blockframe.c: Put get_frame_saved_regs inside #if !defined
6346 (FRAME_FIND_SAVED_REGS).
6348 * findvar.c ({fetch,store}_registers): Check for
6349 REMOTE_{FETCH_STORE}_REGISTER macro.
6351 * findvar.c (get_saved_register): Add argument lval and
6352 change meaning of argument addr.
6353 findvar.c: Change calls to get_saved_register to reflect
6354 new calling convention.
6355 valops.c (value_assign): Use get_saved_register instead of
6356 find_saved_register.
6358 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
6360 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
6361 an (uninitialized) pointer to one. Use "&" when passing it
6364 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
6366 * coffread.c (getfilename): Use DGUX x_offset and x_name if
6369 * coffread.c (symbol_file_command): Put semicolon after
6371 Put safe_to_init_tdesc_context in #if defined (TDESC).
6372 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
6373 coffread.c: #include <sys/stat.h>.
6374 (read_coff_symtab): Typo: in_source_files -> in_source_file.
6375 Add missing ')' in check for "lc%" and friends. Remove
6377 Declare read_one_sym() at top of file.
6378 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
6379 MC68WRMAGIC can have the same value without causing a duplicate
6382 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
6384 * Allow a Makefile to be built without building the
6385 tm and xm file links that screw up builds in subdirectories.
6386 This is done with `config.gdb none', then you can do things
6387 like `make gdb.tar.Z'.
6388 * tconfig/none: Config file for no target system
6389 * xconfig/none: Config file for no host system
6390 * config.gdb: If no TM or XM files are called out by the
6391 host or target file, don't make links for them.
6393 * cplus-dem.c: Add documentation.
6395 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
6396 simple error, so the user's gdb doesn't crash due to some object
6397 file problem (e.g. somebody is rebuilding the file out from under
6400 * printcmd.c (print_address_symbolic): demangle the symbol.
6402 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
6403 Motorola copyrights in it. Make "make gdb.tar.Z" work.
6404 (alldeps.mak): sort and uniq all results from this; duplicates
6405 hose gdb.tar.Z link building. Remove RCS files from
6406 tconfig and xconfig. Add config files for sun386. Add
6407 a few odd files to OTHERS and HFILES.
6409 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
6411 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
6412 Roll version number to 3.91.5. Make lint work in bindir.
6414 * README: Document cross-debugging and new file structure.
6416 * blockframe.c: Lint. Include "value.h" to declare read_register.
6417 (find_pc_partial_function): remove duplicate line.
6419 * command.h: Lint. Declare error_no_arg and dont_repeat.
6421 * tm-news.h: Remove inadvertently duplicated stuff.
6423 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
6424 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
6426 * config.gdb: Allow `config.gdb host target' form. Clean
6427 up previous change that printed bogus messages when you just said
6430 * core.c: #include "command.h" for lint.
6433 * main.c: Remove some casts of enums. Lint.
6440 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
6442 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
6443 read it from memory. This will allow us to save ptrace calls
6444 eventually. Changed caller single_step too.
6446 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
6447 that we aren't going to use, saving many ptrace calls, especially
6448 when watchpointing or single stepping. Use some #define's for
6450 (store_inferior_registers): Ditto.
6451 (core_file_command): Use some #define's for constants.
6453 * tm-sparc.h: Add #define's for some register numbers, so we
6454 can eliminate the use of random constants in sparc-xdep.c.
6456 * stack.c (frame_command, print_frame_info, up_command,
6457 down_command) Remove frame_changed, since it
6458 causes a bug and doesn't seem to do anything useful. In some
6459 places it was used as a flag, in others as a stack level (?).
6461 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
6462 default is to use the portable (vprintf) version rather than the
6464 * xm-news.h (MISSING_VPRINTF): Add.
6466 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
6468 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
6470 * Remove stuff that forces -Bstatic linking of gdb, and warnings
6471 about linking debugged programs -Bstatic in the sun?os4 config
6472 files in tconfig and xconfig subdirectories.
6474 * main.c (main): Remove unreached exit(0) now that we exit
6477 * Create TODO file for online bug list. There are too many
6478 "little" bugs to keep track of on paper.
6480 * Change Projects file to refer to bug-gdb@cygnus.com
6481 rather than kingdon@ai.
6483 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
6485 * Makefile.dist (VERSION): 3.91.4 now.
6487 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
6488 (condense_misc_bunches): Add sanity check that misc_count is
6489 the same as the number of symbols in the bunch.
6491 * coffread.c: rename init_misc_bunches. Pass an argument
6492 to condense_misc_bunches (a zero).
6494 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
6495 every time we are called; don't rely on our caller to do it.
6496 (add_file): Remove call to init_misc_bunches.
6498 * mipsread.c: Only warn, don't error, if unknown symbol types.
6499 This keeps an old gdb from falling on its face if it sees newly
6500 extended symbol info. Rename init_misc_bunches.
6502 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
6504 * Merge in changes from Per Bothner for DECstations and other
6505 MIPS stuff. The rest is Bothner speaking:
6507 The next message is a merger of Alessando Forin's mips port with
6508 mine. I've tried to use my good if biased judgment to get
6509 the best of both. It *does* need testing.
6511 Some of the changes are general, *not* mips-specific.
6514 Didn't believe in little-endian bit order.
6515 There are still inconsistencies about whether flags
6516 like BITS_BIG_ENDIAN are integer (#if ...) or
6517 boolean (#ifdef ...). I tried to paper over them.
6519 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
6520 Moved some misc_function code that was common to
6521 {dbx,coff,mips}read.c to symtab.c.
6522 In the process, I think I cleaned things up a bit.
6523 At the same time, moved obsavestring and obconcat to symtab.c.
6526 Removed obsolete condense_addl_misc_bunches (use
6527 condense_misc_bunches(1) instead).
6530 Needed to include <sys/dir>, at least on DECstations.
6532 valops.c, mips-tdep.c, tm-mips.h:
6533 Added PUSH_ARGUMENTS macro to support funny argument-pushing
6534 conventions (when STACK_ALIGN is insufficient).
6535 Needed on mips, where doubles need 8-byte alignment,
6536 but ints only need 4.
6539 Removed cruft that was not being used.
6540 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
6543 Print $ before register-names (I think that makes things a little
6545 Never print two instructions, even if one delays.
6546 Removed hex-disassemble set_cmd. (This is not mips-specific,
6547 so I think the argument is whether it is generally worthwhile or not.
6548 I'm inclined to think not, given how easy it is to
6549 convert between radixes in gdb.)
6552 This is basically Alessando's code.
6553 It doesn't use obstacks; I changed it to use obstacks
6554 in a few minor places where using malloc causes a
6555 memory leak. (Probably, more places could/should be changed.)
6556 I added record_misc_function where it was missing.
6557 In symbol_file_command and add_file_command, I tried
6558 to make the code consistent with more recent versions.
6559 Minor sylistic changes in parse_procedure.
6560 Make a .gdbinfo. psuedo-symbol point back to the real
6561 procedure symbol (using the isym field).
6564 This is basically from my port, but with a lot of details
6565 and a number of routines merged in from Alessando's version.
6566 I basically used my code "raw" backtrace (use heuristics
6567 from the actual code, rather than symbol table info) - though
6568 the idea is Alessandro's. I feel my code is a little cleaner
6569 here, particularly in being a little more flexible, such as being
6570 able to handle gcc-produced code (which it now can).
6571 It also doesn't do frame caching (which is not useful
6572 more recent gdb versions).
6573 I also used my code for push_/pop_dummy, more or less.
6574 I tried to incorporate AF's code for testing sigtramp
6575 while backtracing; I probably got it wrong.
6576 Added mips_print_register, which tries to scrunch as much
6577 information as possible on a screen...
6578 Removed the skip-prologue set_cmd. As with hex-disassemble (see
6579 under mips-pinsn.c), I don't see anything mips-specific here,
6580 and I don't see it being all that useful anyway.
6583 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
6584 Use more register names (rather than hard-cases numbers).
6586 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
6588 * Hack up 3.90.11 changes:
6590 * Makefile.dist (depend): parameterize $(GCC).
6591 Add solib.c and solib.o.
6592 (readline): Fix vpath for both absolute or relative SRCDIR.
6594 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
6595 Also, let the part I didn't understand at least compile so
6596 I can test the rest. FIXME.
6598 * dbxread.c: Fix thinko using strcmp.
6599 (init_psymbol_list): declare static.
6600 (partial_symbol_file_open): Comment cleanups better, avoid
6601 cleaning up the string table since the caller will do that.
6602 Move the stat for mod time into symbol_file_command, temporarily.
6603 (There should be a mod time for each symbol file, eventually,
6604 to control its rereading. FIXME.)
6606 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
6607 SunOS, which gives error for shared libs otherwise. (From
6608 Schaefer, probably FIXME needs work for portability.)
6610 * solib.c: Move #include "param.h" to work.
6611 Lowercase all the Uppercase Letters In the Messages.
6612 (find_solib): Clean up inferior_so_name for debug printouts.
6613 Allow no argument, to mean all shared libraries.
6615 * symmisc.c: include param.h to get CLEAR_SOLIB.
6617 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
6619 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
6620 to 3.90.11. ChangeLog entries below are from this.
6622 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
6626 * Makefile.dist (HFILES): Add tm-sunos.h.
6628 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6632 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
6634 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
6636 * sparc-opcode.h Added single-operand version of rett.
6638 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6640 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
6641 Put parens around gcc_p in expansion.
6643 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
6645 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
6647 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6649 * Changes for Sun shared libraries:
6650 blockframe.c (find_pc_partial_function): If a non-text symbol
6651 is found, set *address = pc - FUNCTION_START_OFFSET.
6652 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
6653 Disable breakpoints instead of giving an error.
6654 source.c (select_source_symtab): Initialize cs_pst.
6655 symmisc.c: Call CLEAR_SOLIB if defined.
6656 symtab.h: Make text{low,high} CORE_ADDR not int.
6657 (psymtab): New field addr.
6659 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
6660 (record_misc_function): Give correct type for N_DATA symbols.
6661 (condense_misc_bunches): do "misc_function_count = j" regardless
6663 Take code which is shared between symbol_file_command and
6664 add_file_command and put it into partial_symbol_file_{open,read}.
6665 Split add_file_command into add_file_command and add_file.
6666 Make psymtab_to_symtab read in the string table if the file
6668 Two new parameters to read_dbx_symtab and start_psymtab.
6669 tm-sunos.h: New file.
6671 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6673 * infcmd.c: Change cont_command to continue_command and "cont"
6676 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6678 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
6680 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
6682 * values.c (USE_STRUCT_CONVENTION): Check for structures of
6683 size 1,2,4,8 rather than size < 8.
6685 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
6686 as necessary, not just once.
6688 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
6690 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6692 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
6694 * tm-news.h: Add CALL_DUMMY_*.
6696 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
6698 * config.gdb: In list_host, list_target, use ${i}, not $i.
6700 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6702 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
6704 * sparc-opcode.h: Change all store floating-point state register
6705 instructions to have the right match & lose fields.
6707 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6709 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
6711 config.gdb: If srcdir != ., create readline directory and
6712 copy a makefile into it.
6714 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
6715 consistency with POSIX.
6717 * breakpoint.c (bpstat_stop_status): Disable watchpoint
6718 when we exit its exp_valid_block.
6720 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
6722 * Makefile.dist: Bump version to 3.91.3.
6724 * Clean up handling of breakpoint commands (somewhat).
6725 Prompted by Tiemann bug report "cont 10" doesn't work any more.
6727 inferior.h: Add breakpoint_proceeded to inferior status struct
6728 and globals; save it and restore it.
6729 (clear_breakpoint_commands): Cleanup, remove old #define.
6731 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
6732 (save_inferior_status, restore_inferior_status): handle it also.
6733 (proceed): Remove earlier code that set breakpoint_proceeded.
6734 It is now set only in clear_proceed_status.
6735 (clear_proceed_status): Cleanup, use bpstat_clear rather
6736 than clear_breakpoint_commands. No callers need the stop_bpstat
6737 between clear_proceed_status and proceed.
6739 infcmd.c: Add breakpoint_proceeded definition and comment.
6740 (cont_command, jump_command, signal_command): Move call to
6741 clear_proceed_status right next to call to proceed.
6743 breakpoint.c (bpstat_do_actions): Avoid clobbering our
6744 caller's argument while running down the chain of breakpoints.
6745 Use new variable "breakpoint_proceeded" to determine when
6746 a command that it executes moves the inferior past the
6748 (bpstat_clear): Handle NULL argument.
6749 (bpstat_clear_actions): Avoid useless call to
6750 breakpoint_auto_delete.
6751 (delete_breakpoint): Clean up bpstat's that are pointing to
6752 the deleted breakpoint from the stop_bpstat chain.
6753 (breakpoint_auto_delete): Simplify.
6755 * Clean up handling of EOF, error on stdin, etc. This was
6756 prompted by a network problem that caused gdb to go into an
6757 infinite loop filling up its malloc'd memory.
6759 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
6760 not clear_breakpoints_commands, which is now gone.
6761 (main): If command_loop returns (e.g. from EOF on stdin), do
6762 a quit_command (looping back to command_loop if quit_command
6763 doesn't really quit).
6764 (command_loop): check result from command_line_input and
6765 exit if it returns NULL, rather than passing the NULL to
6767 (gdb_readline): Free malloc'd result space before returning
6770 * utils.c (query): Handle C-d to mean "yes", just as if the
6771 input was not a terminal. Also avoid infinite loop if EOF
6772 occurs in mid-input-line before newline. This allows
6773 query to be used at EOF on stdin with reasonable results.
6775 * infrun.c (proceed): Set breakpoint_proceeded.
6777 * values.c (value_as_long): Avoid infinite recursion for enums.
6778 (_initialize_values): Fix typo in help msg (kingdon).
6780 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
6781 RL_LIB for linking. This allows -lreadline for linking
6782 and nothing for dependencies, once readline is a real library.
6784 * config.gdb: Jim Kingdon: give useful error message if the
6785 host or target type is not recognized.
6787 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
6788 it just defines it. Dumb, but deal with it.
6790 * Jim Kingdon suggests:
6791 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
6793 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
6795 * Makefile.dist (VERSION): Bump version # to 3.91.2.
6797 * Clean up Bothner's changes.
6799 * blockframe.c (clear_pc_function_cache): New function.
6800 * blockframe.c: remake cache_pc_function_* static.
6801 * dbxread.c (symbol_file_command): remove references to
6802 cache_pc_function_* variables.
6803 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
6804 * printcmd.c: Avoid kludging a global variable (addressprint)
6805 to avoid printing the address of a string twice. Instead,
6806 pass the format letter 's' down low enough that it can be seen
6807 to avoid this problem.
6808 (print_formatted): Pass format arg to value_print.
6809 (restore_addressprint): Remove function.
6810 (do_examine): Avoid hacking addressprint, cleanups and such.
6811 (print_frame_args): Add a comment to a Bothner change.
6812 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
6813 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
6814 to wipe out the values cached in blockframe.c.
6815 * symtab.c (find_method): Add comment saying how big you must
6816 allocate to be "big enough". Per being terse again.
6817 * valprint.c (val_print): Handle format letter "s" to print
6818 strings without addresses. Add comment to vtbl printing code
6819 which casts with wild abandon. Rearrange reference-printing
6821 @0xaddr: value (print w/addressprint)
6822 value (print w/~addressprint)
6823 @0xaddr (parameter lists w/addressprint)
6824 or nothing (parameter lists w/o addressprint)
6826 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
6828 * Merge more changes from Per Bothner:
6830 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
6831 annoying) that I tried to improve it. Here are my suggestions.
6833 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
6836 Do automatic de-reference when taking the address of a reference.
6838 Don't deref_ref when printing parameter lists.
6840 More attempts at treating refernences properly.
6842 In val_print, if deref_ref==0, don't print dangling " = ".
6844 Add COERCE_REF macro, which de-references an REF.
6846 * Merge changes from Per Bothner:
6848 * Fixed (Sony news)-specific configuration problems.
6849 * Fixed other problems with using vanilla pcc and libc (enum problems;
6850 assumption that vsprintf exists).
6851 * Some major speed-ups (finc_pc_partial_function now caches a match;
6852 parsing avoids duplicate symbol_lookup calls).
6853 * Changed handling of baseclasses (no longer use baseclasses field
6854 of struct type, use the first n_baseclasses fields instead).
6855 * Various minor changes/fixes, most C++-related.
6858 Cache the most previous match from find_pc_partial_function.
6859 (Save both low and high ends of matching function's pc range.)
6860 This speeds up the loop of infrun.c:wait_for_inferior quite
6861 a bit, and makes step/next commands much zippier.
6863 Added an enum->int cast (otherwise, some compilers barf).
6865 No longer set baseclass offset to 0, since multiple
6866 inheritance now mostly works.
6867 Added a number of casts, to shut up compiler warnings
6868 (after stabs where made enums, not ints).
6869 When discarding a symbol table (in symbol_file_command),
6870 must clear the cache introduced in blockframe.c.
6871 Don't convert $vtbl_ptr_type to vtbl any more.
6872 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
6873 Mask off sign bit emitted by g++ for virtual table offset.
6874 Set voffset to -1 (not 1) for static member functions.
6876 Changed parsing/lexing of names to avoid doing symbol lookup twice
6877 (once when lexing to determine symbol class, once for real).
6878 Now only call symbol_lookup once. Fields of 'this' win especially big.
6880 Subpress printing addr twice in the case of 'x/s addr'.
6882 lookup_basetype_type is no longer used.
6883 Add find_methods as recursive helper function to decode_line_1.
6884 This allows multiple inheritance to work.
6885 Also, once one or more matches has been found, do not look in
6886 base-classes. (Baseclass methods would be overridden, anyway.)
6888 Removed baseclasses array in struct type.
6889 Instead of using baseclasses[i], use fields[i-1].
6890 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
6891 Changed sign convention of voffset (previous was inconsistent).
6893 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
6895 Used to assume existence of vsprintf. Re-written to not need it
6896 if HAVE_VPRINTF is undefined.
6898 typecmp was too pessimistic. Made it less so.
6900 Don't print space after address.
6901 If vtable points to a misc symbol (with 0 offset), print it,
6902 since that indicates the actual class of the object.
6903 Changed ype_print_derivation_info to use new inheritance
6904 scheme (without baseclasses vector).
6906 In value_primitive_field, fixed some bugs left over from previous set of fixes.
6907 Also, changes needed because TYPE_BASECLASSES were removed.
6909 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
6911 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
6914 If there is no path set, and the symbols don't indicate what directory
6915 a file was compiled in, look in the current directory. But either
6916 a path or a known compilation directory will prevent this.
6919 Three independent bug fixes:
6920 * Remove the #if 0 block that breaks some stuff.
6921 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
6922 adapt gdb to either SunOS 4.0.* or 4.1.
6923 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
6926 Instantiate the class T when looking for methods in it. (Tiemann@sun)
6929 (type_print) Demangle the name being printed.
6930 (type_print_base) Handle botched demangling without coredump (tiemann).
6933 (check_stub_method): Document routine.
6934 (tiemann) fix bug for no-arg functions
6935 Avoid clobbering beyond end of malloc'd storage.
6936 Terminate the argument list properly.
6938 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
6940 * Changes merged by John Gilmore:
6943 In breakpoint_1, use new print_address_symbolic instead
6944 of find_pc_partial_function. (This forces use of assembler-level
6945 addresses, and avoids misleading non-mangled source-level names.)
6947 Generalize ansi argument such that -1 means skip arglist totally.
6948 Removed global variable print_ansi_qualifiers (which made
6949 code non-reentrant), in favor of extra explicit arguments
6950 to internal routines.
6952 Add new helper function print_address_symbolic.
6953 Use find_pc_misc_function instead of find_pc_partial_function
6954 (since we want assembler-level symbols here).
6956 Print unknown function as just "f (...)", not "f (...) (...)".
6957 Use new fputs_demangled explicitly.
6959 Fixed a typing violation (problem: value.h cannot be imported
6960 without renaming many variable in this file).
6961 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
6962 decode_line_1: Moved forward some never-reached code.
6963 Made decode_line_2 skip function prologues correctly.
6965 fputs_filtered should not demangle by default.
6966 Add new fputs_demangled to demangle on demand..
6968 Change value_struct_elt to use value_primitive_field (using recursive
6969 utility function search_struct_field). This allows foo.bar to work
6970 for multiple inheritance (so far only for data fields).
6971 Change check_field in the same way (recursive helper function
6972 to support multiple inheritance).
6973 (Note: there are more of these problems that I haven't fixed.
6974 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
6975 value_of_this: 'this' symbol name is now just "this", note "$this".
6977 Don't print static members.
6978 Avoid printing "members of <type>" if there are none.
6979 Simplified type_print_derivation_info by merging duplicate code.
6980 Remove useless blank lines in type_print_base (ptype command).
6982 Added declaration of new routine value_primitive_field.
6984 Added value_primitive_field which is generalized version of
6985 value_field that can handle multiple inheritance (non-zero offsets etc).
6986 Re-implemented value_field to call value_primitive_field.
6988 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
6990 * infcmd.c -- insert else to avoid 'delete env' coredump when you
6991 delete the whole environment. Karl Berry reported the bug.
6992 * source.c - fix openp to avoid //'s in filenames, which
6993 trigger an Emacs bug causing it to not be able to find files
6994 when running gdb in a window.
6995 * dbxread.c - zap the #if 0 that botches the add-file code.
6996 It seems to work a lot better without all the code commented out.

7006 added remote-sa.sparc.c
7007 * added remote.sa-sparc.c, a modification of remote.c
7008 which conducts a dialog directly with the SparcStation prom.
7009 * breakpoint.c, infrun.c, sparcdep.c added
7010 remote_insert_breakpoint(), and remote_remove_breakpoint()
7011 to breakpoint.c instead of directly writing breakpoint instructions.
7012 * sparcdep.c on remote_debugging,there is no need
7013 to remove signle step breakpoint instructions.
7014 * main.c added "-epoch" flag and "int epoch_interface" to main.c
7016 * printcmd.c - epoch interface sends lisp expressions to open up
7017 epoch windows on inspection.
7018 * valprint.c - added arrayprint, and addressprint and made adding
7019 format controls easier
7020 * wait.h added a couple of undef's because we were getting
7021 complaints about WSTOPSIG and WTERMSIG begin redefined.

7091 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
7092 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME

7117 step_resume_break_address != NULL, even if another_trap.
7118 If trap_expected and we enter sigtramp, then set up a
