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

514 * dwarfread (enum_type): Arrange for the order of enumeration
515 members to match the source code order; not the order in the
516 Dwarf information, which is explicitly reverse order.
518 Wed Dec 4 18:24:39 1991 John Gilmore (gnu at cygnus.com)
520 * main.c (input_from_terminal_p): Check whether GDB has a

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

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

616 Eliminate TYPE_MAIN_VARIANT and TYPE_NEXT_VARIANT. Eliminate
617 lookup_method_type. Add TYPE_TYPE_SPECIFIC macro.

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

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

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

800 Sun Nov 17 16:20:53 1991 Michael Tiemann (tiemann at rtl.cygnus.com)
802 * symtab.h (struct type): Moved C++-specific fields into new type
803 `struct cplus_struct_type'. Now takes 10% less memory. Many

806 TYPE_CPLUS_SPECIFIC unless TYPE is TYPE_CODE_STRUCT.
807 * buildsym.c (read_type): Allocate TYPE_CPLUS_SPECIFIC for
809 (read_struct_type): Ditto. Also, add comments about how we can
810 deduce TYPE_VPTR_FIELDNO from inheritance info and fieldname info.
811 * coffread.c (decode_base_type): Allocate TYPE_CPLUS_SPECIFIC for
813 (read_struct_type): Ditto.
814 * dwarfread.c (struct_type): Ditto.
816 * symtab.c (read_range_type): Don't set TYPE_MAIN_VARIANT.

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

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

895 * tdesc.c, tdesc-lib: FIXME: remove these.
897 Tue Nov 12 19:30:22 1991 John Gilmore (gnu at cygnus.com)

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

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

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

1005 (dbx_lookup_type): Handle null typevector.
1006 (dbx_alloc_type): Check file number, not sym number, for -1.
1007 (find_symbol_in_list): Add for xcoffread.
1008 (start_symtab): Default typevector is empty. Keep reusing same
1010 (end_symtab): Take objfile argument and pass it to
1011 allocate_symtab. Don't make a symtab if no blocks or symbols.
1012 Handle empty typevector.
1013 (push_context): New function for context stack nesting.
1014 (read_type): Mark FIXME where we need to reintroduce type smashing.
1016 * buildsym.h (pop_context): Macro, paired with push_context.
1017 (subfile_stack): Move here from dbxread.c.
1019 * coffread.c (end_symtab, read_coff_symtab): Take and use objfile arg.
1020 (read_coff_symtab): Cleanup by freeing objfile, not all symtabs.
1022 * mipsread.c (read_mips_symtab, parse_partial_symbols, parse_fdr,
1023 new_psymtab, new_symtab): Take and use objfile arg.
1025 * dwarfread.c (scan_compilation_units, start_psymtab,
1026 process_dies, end_symtab, dwarf_build_psymtabs,
1027 read_lexical_block_scope, read_func_scope, read_file_scope): Take
1028 and use objfile argument.
1029 (psymtab_to_symtab_1, read_ofile_symtab): Don't take or use file
1030 descriptor. Use BFD internal functions instead.
1031 (end_symtab): Call global allocate_symtab.
1033 * elfread.c, target.c: Minor changes to accommodate objfiles.
1034 * symtab.h: partial_symbol_table has no symfile_name member now.
1035 (fn_fieldlists voffset): avoid non-int bitfield.
1036 (struct symtab): Add objfile * and objfile_chain * of symtabs.
1037 (struct partial_symtab): Add objfile * and objfile_chain * of
1038 psymtabs. Remove symfile_name.
1040 * symmisc.c: Lose free_all_symtabs, free_all_psymtabs.
1041 (printsyms_command): Rename from print_symtabs. Add selective
1042 listing if 2nd argument given. Print objfile info.
1043 (printpsyms_command): Rename from print_partial_symtabs. Ditto all.
1044 (printobjfiles_command): New; prints objfiles lists, and checks
1045 for consistency of symtab, psymtab, and objfile lists.
1047 * symfile.h, symfile.c, symtab.h: Lint
1049 Fri Nov 8 23:38:48 1991 John Gilmore (gnu at cygnus.com)
1051 * command.c: Include param.h.
1052 * defs.h (warning_setup, warning): Declare.
1053 * expprint.c (print_subexp, UNOP_MEMVAL case): Lint.
1054 * inflow.c (new_tty): Use USE_O_NOCTTY #define.
1055 * language.c, printcmd.c (print_scalar_formatted), signame.c,
1058 Thu Nov 7 18:26:15 1991 Steve Chamberlain (sac at rtl.cygnus.com)
1060 * Makefile.in: link with libiberty after libreadline, since
1061 readline might want something in libiberty.
1062 * m88k-xdep.c: Fixed the register offsets in the ptrace_user
1063 struct for BCS 88k machines.
1064 * xm-m88k.h: don't define USIZE if already defined.
1065 * configure.in: Added delta88 target.
1067 Thu Nov 7 04:51:19 1991 John Gilmore (gnu at cygnus.com)
1069 * am29k-pinsn.c, am29k-opcode.h: Fix decoding of mtacc, dmac, fmac.
1071 * tm-*.h: Remove READ_DBX_FORMAT, COFF_FORMAT, and
1072 READ_MIPS_FORMAT, which have been unused since BFD. Still
1073 remaining is COFF_NO_LONG_FILE_NAMES.
1074 * tm-sun3.h, tm-altos.h: Remove detritus accidentally left from
1075 function calling code moved to m68k-tdep.c.
1077 Wed Nov 6 17:21:59 1991 John Gilmore (gnu at cygnus.com)
1079 * coffread.c: Eliminate c_nsyms in favor of c_naux.
1080 Complain if no auxents on .bf and .ef FCN symbols, and assume
1081 lots of line numbers.
1082 (init_linenos, enter_linenos): Use a sentinel at the end of the
1083 read-in linenos, to make for a fast, safe loop-end test.
1085 Wed Nov 6 02:54:08 1991 Steve Chamberlain (sac at cygnus.com)
1087 * coffread.c (read_coff_symtab): coffread used to rely on the
1088 x_sym.x_misc.x_lnsz.x_lnno field giving the # of linnos in a
1089 function. Two of the formats I'm using (29k and 88k) don't seem to
1090 set it. Ths patch to fcn_last_line and (enter_linenos) is an
1091 attempt to use the actual size of the linno table in the file to set
1092 the number of linenos to process.
1094 Tue Nov 5 22:47:46 1991 Steve Chamberlain (sac at cygnus.com)
1096 * Makefile.in: put a - infront of the mv y.tab.c c-exp.tab.c and
1097 mv y.tab.c m2-exp.tab.c, so that if bison is used, and the files
1098 are created in place, so the mv fails, then the make continues.
1100 Tue Nov 5 16:47:47 1991 Per Bothner (bothner at cygnus.com)
1102 Add C++ as a separate language.
1103 * defs.h (enum language): Add language_cplus.
1104 * dwarfread.c (end_symtab): Support language_cplus.
1105 * c-exp.y: Add new struct language_defn cplus_language_defn.
1106 Don't set c to be the default language (see main.c).
1107 * c-exp.y (yylex): Only look for field of this if
1108 language is C++. (First difference from C!)
1109 * language.c: Add case branches for C++ (currently, all
1110 the same as C). Also, add c++ to "usage" note for "set lang".
1111 * valprint.c (typedef_print). Add case branches for C++.
1112 * main.c (main): New way to set initial language: Look at
1113 file extension of psymtab containing main(). (Same as we
1114 do for symtabs, but avoid loading the symtab yet.)
1115 * symtab.c: New routine find_main_psymtab(), used by main()
1116 to set initial language.
1117 * symfile.c (allocate_symtab): Move code for mapping file
1118 extensions-> languages to new deduce_language_from_filename().
1120 Fix a C++ problem when looking for methods in super-classes.
1121 There was confusion between base and derived types.
1122 * valops.c (value_fn_field): Change function interface.
1123 * values.c: Use new value_fn_field interface.
1125 Mon Nov 4 10:49:33 1991 Per Bothner (bothner at cygnus.com)
1127 * infrun.c: Fixed typo in comment.
1128 * utils.c: All the v*fprintf emulation is now in libiberty,
1129 so we can get rid of some junk.
1130 * xm-sun3os4.h, xm-sun4os4.h, xconfig/decstation, xconfig/i386sco,
1131 xconfig/sun3os4, xconfig/sun4os4: Don`t need HAVE_STRSTR any more.
1132 * m68k-pinsn.c (print_insn_arg): Support BB/BW/BL
1133 type operands, as used by branch instructions.
1134 * gmalloc.c: Fix prototype of memcpy.
1135 * elfread.c: Comment out register_addr, since it conflicts
1136 with the one in coredep.c.
1137 * buildsym.h: Remove extern declarations of two functions
1138 that are really static in buildsym.c.
1139 * tm-mips.h: Add symbolic names for more registers.
1140 * mips-xdep.c (store_inferior_registers): Use new register names.
1141 * xm-mips.h: Simplify REGISTER_U_ADDR, since it is now
1142 only used for core files, not ptrace. Therefore,
1143 the KERNEL_U_ADDR hack is no longer needed.
1144 The mapping to ptrace number is now in in mips-xdep.c.
1145 * mips-xdep.c: Define REGISTER_PTRACE_ADDR (using the
1146 mapping from the old REGISTER_U_ADDR), and use it
1147 in {fetch,store}_inferior_registers.
1148 * mipsread.c: Rename #include ecoff.h to new name coff-mips.h.
1149 * mips-tdep.c (mips_push_dummy_frame, mips_pop_frame):
1150 Save/restore FP regs correctly (?).
1151 * dbxread.c: Remove duplicate define_symbol and type_synonym_name
1152 (these had been previously moved to buildsym.c).
1153 Hence, define_symbol becomes extern instead of static.
1154 * buildsym.c (read_struct_type): Comment out bogus handling
1155 of C++ operator methods. Minor hacking of reading of class
1156 contexts. Make define_symbol non-static, so dbxread.c can call it.
1158 Fri Nov 1 11:05:47 1991 John Gilmore (gnu at cygnus.com)
1160 * mipsread.c (read_mips_symtab, read_the_mips_symtab): Use real
1161 filename with error messages.
1162 * stack.c (frame_select_command): Rename to select_frame_command
1163 to avoid "fr" and "fra" having nonunique completions.
1164 * symfile.c (sort_symtab_syms): Ignore sort of zero symtab *.
1165 (symfile_init): Print file format name when unable to handle it.
1166 (free_named_symtabs): Use BLOCKVECTOR rather than obsolete BLOCKLIST.
1167 * symmisc.c (free_symtab): Only free linetable if nonzero.
1168 * symtab.h: Remove obsolete BLOCKLIST macros.
1170 Thu Oct 31 18:12:43 1991 Stu Grossman (grossman at cygnus.com)
1172 * infrun.c (wait_for_inferior): another stepi/nexti fix. Ensure
1173 that stop_step is 1 at bottom of main loop. I don't know why this
1174 needs to be done, but it helps me sleep better at night.
1176 Sun Oct 27 18:18:39 1991 Stu Grossman (grossman at cygnus.com)
1178 * main.c (initialize_history): Read history after reading all
1181 Sun Oct 27 14:09:25 1991 John Gilmore (gnu at cygnus.com)
1183 * buildsym.c: Break out initial malloc sizes.
1184 (record_line): Record directly in a subfile. Alloc on demand.
1185 (compare_line_numbers): Add from xcoffread.c.
1186 (end_symtab): New params say whether to sort pendings and
1187 linetable. Patch block stabs if defined. Shrink linetable before
1188 allocating the symtab.
1189 * buildsym.h: Delete line_vector* and prev_line_number. Add
1190 global_stabs and file_stabs for xcoffread.
1191 * dbxread.c (start_subfile): Move to buildsym. Change above calls.
1192 * symtab.h: LINETABLE(symtab) can now be null. Zap LINELIST.
1193 * symmisc.c, symtab.c: Cope with null LINETABLEs.
1195 * blockframe.c: Pass fromleaf to INIT_EXTRA_FRAME_INFO.
1196 * tm-29k.h, tm-88k.h, tm-i960.h, tm-irix3.h, tm-mips.h, tm-pyr.h,
1197 tm-sparc.h: Accept fromleaf parameter.
1198 * c-exp.y (yyerror): Pass error message if given.
1199 * configure.in: Add rs6000 host and target.
1200 * inflow.c (new_tty): O_NOCTTY kludge for RS/6000.
1201 * symfile.h (entry_point): Add.
1203 Sat Oct 26 00:16:32 1991 John Gilmore (gnu at cygus.com)
1205 * buildsym.c: New file. Breaks out symbol-table-building routines
1206 from dbxread.c, so they can be shared with xcoffread.c.
1207 * buildsym.h: New file. Declarations for buildsym.c users.
1208 * dbxread.c: Remove large chunks into buildsym.c.
1209 * Makefile.in: Add buildsym.c and buildsym.h.
1211 * symfile.c (syms_from_bfd): New routine.
1212 (add_symbol_file): Call it to do the real work.
1213 (syms_from_bfd): Initialize entry_point before calling symfile_init.
1214 * symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
1215 Avoid declaring or setting entry_point (symfile.h & symfile.c cope).
1217 Fri Oct 25 10:58:16 1991 Mark Eichin (eichin at cygnus.com)
1219 * cplus-dem.c (cplus-demangle): added support for templates, static
1220 data, and the new (correct) mangling for destructors.
1222 * dwarfread.c: (dwarfwarn): created a varargs version of
1223 dwarfwarn, for non __STDC__ compilers.
1225 * c-exp.y: (yylex): added match for "template" token.
1226 (typebase): added TEMPLATE name '<' type '>' clause, for explicit
1227 specification of template types.
1229 * symtab.c: (lookup_template_type): new function for finding
1230 templates in symbol table.
1231 (type_name_no_tag): changed to explicitly check for s/u/e at the
1232 beginning of the symbol - if it is a template, none of these will
1233 be there (but the name will still contain spaces.)
1235 Fri Oct 25 18:59:32 1991 Per Bothner (bothner at cygnus.com)
1237 Various fixes to improve g++ debugging.
1238 * symtab.h: Add is_const and is_volatile flags for each method.
1239 These are bit fields - take their space from voffset,
1240 which shrinks to 30 bits. Since voffset is now a bitfield,
1241 make it unsigned for portability. This changes its interpretation
1242 slightly: Static methods now have voffset 1 instead of -1,
1243 and virtual offsets start at 2, not 1.
1244 * symtab.c: Renamed gdb_mangle_typename to gdb_mangle_name,
1245 since it now returns an entire magled method name, not just
1246 the type part. This avoids some duplication.
1247 It also allows us to correctly mangle const and volatile
1248 methods (using the new is_const and is_volatile bit fields
1250 * valprint.c (type_print_base), values.c (check_stub_method):
1251 Simplify by using new gdb_mangle_name.
1252 * values.c (value_headof): Fix to correctly handle single
1253 inheritance (actually two fixes, either of which suffices).
1254 * dbxread.c (read_struct_type): Handle const and volatile
1256 * dbxread.c (read_struct_type): Yet one more place where
1257 we must handle '\\' continuations.
1258 * valprint.c (vtbl_ptr_name): Add final '\0'.
1260 Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com)
1262 * tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of
1263 short return values for sparc and 68k. Patch from Paul Eggert.
1265 * coffread.c, coredep.c, i386-xdep.c: install patches for
1266 SysV/386 3.2 from Mauro DePalma.
1268 Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
1270 * core.c (core_file_info), exec.c (exec_file_info): Print file
1271 type. Use printf_filtered.
1273 * valops.c (value_fetch_lazy): Avoid 0-length fetches.
1275 Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
1277 * dwarfread.c: Add casts to remove compiler warnings.
1279 * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
1280 tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
1281 tm-sun3.h: Remove locally duplicated code for calling functions
1282 in the inferior. The only differences were in the specific trap
1283 vectors used and whether or not an fpu was present. These are
1284 now handled by appropriate definitions of BPT_VECTOR and
1285 HAVE_68881 respectively. Other minor obvious cleanups.
1287 * valops.c: Correct a minor misspelling.
1289 * utils.c: Remove local BSD/USG hacks that are now in libiberty.
1291 * dwarfread.c: Remove prototype for dwarfwarn. Does not work
1294 Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
1296 * stack.c (frame_command): Always print. Use new
1297 frame_select_command to select a frame without printing.
1299 * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
1301 Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
1303 * dwarfread.c: New file for DWARF debugging format support.
1305 * elfread.c: New file for ELF object file format support.
1307 * procfs.c: New file for SVR4 /proc (process file system) support.
1309 * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
1312 * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
1314 * xm-m68k.h: New file for host machines with m68k cpu.
1316 * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
1317 Add elfread.o and dwarfread.o to OBS.
1319 * symfile.h: Add "elf" to list of supported formats in comment.
1321 * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
1322 types to gdb, builtin_type_long_double, builtin_type_complex, and
1323 builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
1324 TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
1325 TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
1326 TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
1327 types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
1329 * infrun.c: When using SVR4 /proc interface instead of ptrace(),
1330 call proc_set_exec_trap() to setup child to stop at first instruction.
1332 * inftarg.c: When using SVR4 /proc interface, call proc_wait()
1335 * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
1336 supply_fpregset(), and fill_fpregset(), which are machine
1337 dependent support routines for SVR4 /proc interface.
1339 * utils.c: Add warning_setup() and warning(). Warning() behaves
1340 the same as error() except that it returns normally rather than
1341 jumping back to command level. Modules that don't want to call
1342 warning() for some reason, but want to produce their own warnings,
1343 can call warning_setup() to ensure compatibility with the way
1344 warning() and error() deal with the terminal.
1346 * symtab.c: Make internal errors produce more useful messages.
1348 * tm-68k.h: Move code that is duplicated in almost every single
1349 m68k based machine's configuration files to this common file.
1350 Duplications in the configuration files still need to be removed
1353 * infrun.c (child_create_inferior): System V versions must call
1354 setpgrp() with no arguments, to comply with prototyping typically
1357 * munch: Add support for SVR4 style nm output.
1359 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
1360 file specific fields from the partial symbol table structure and
1361 replace them with a pointer to private data for each different
1362 flavor of object file reader to initialize appropriately.
1364 Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
1366 * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
1369 * mipsread.c (fixup_undef_type): New function. If a struct /
1370 union / enum is defined in a header file but nowhere else used,
1371 (by typedefing, pointer referencing or declaration) the mipsread code
1372 builds the complete tree for the structure but leaves its code as
1373 TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
1374 Guess its type based on the details of the members.
1376 Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
1378 * infrun.c (wait_for_inferior): Check return value from
1381 Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
1383 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
1384 by my last edit to this routine.
1386 Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
1388 * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
1389 FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
1390 the values before putting them into the dummy code. (From Peter
1393 Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
1395 * configure.in: added ebmon target.
1397 Wed Oct 16 22:49:58 1991 John Gilmore (gnu at cygnus.com)
1401 * Makefile.in: Roll VERSION to 4.2.
1402 * README, TODO, WHATS.NEW: Update.
1404 * core.c (core_open): Improve error message for bad file.
1405 Pass .reg virtual memory address to fetch_core_registers to help
1406 it find the registers in the core-file header.
1407 * coredep.c (fetch_core_registers): Take new argument, use it,
1408 and pass it to register_addr to locate the block of registers.
1409 * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
1411 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
1412 Sequent N_FN_SEQ like everybody else's N_FN.
1414 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
1415 * tm-i386v.h: #endif guck.
1416 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
1417 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
1418 * xconfig/tahoe: Add REGEX, which seems to be missing.
1420 * coredep.c: Add <sys/types.h> for SCOnix.
1421 * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file.
1422 * printcmd.c (print_formatted): Flush output before disassembly.
1424 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1426 * doc/refcard.tex (sec "Working Files"): consistent metavars and
1427 other improvements, due to comments by François Pinard
1428 (pinard@iro.umontreal.ca)
1430 * doc/gdb.texinfo (appendix "Installing GDB"): changes in
1431 configure, and improvenets related to Pinard's refcard comments
1433 Tue Oct 15 08:45:12 1991 John Gilmore (gnu at cygnus.com)
1435 Changes from Fred Fish:
1436 * tm-68k.h (FPI_REGNUM): Add.
1437 * infrun.c (child_create_inferior): flush stdout and stderr
1439 * configure.in: Handle amigados, amix hosts and targets.
1440 * inflow.c: Handle TIOCGLTC_BROKEN for Amiga.
1442 From Andreas Schwab:
1443 * values.c (show_convenience): Use printf_filtered.
1444 * main.c (define_command): Check result of lookup_command for
1446 (echo_command): Use printf_filtered, and force output out.
1448 * dbxread.c (read_enum_type): Avoid Modula-2 kludge that breaks C
1450 * i387-tdep.c (double_to_i387): Fix typo for double_to_ieee_extended.
1451 * utils.c (_initialize_utils): If !ISATTY, don't paginate.
1452 * configure.in, tconfig/decstation, xconfig/decstation: Rename
1453 dec3100 to decstation.
1455 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)
1457 * doc/gdb.texinfo: Catch up to changes recorded here in ChangeLog
1458 (nodes Continuing and Stepping; Memory; Targets) clarifications
1461 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
1463 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move
1464 REGISTER_U_ADDR to corresponding xm- file. Sugg. by Peter Schauer.
1466 * symmisc.c (print_partial_symtabs): Add printpsyms debug cmd.
1468 * m68k-tdep.c (m68k_push_dummy_frame, m68k_pop_frame): Add
1469 generic routines for calling inferior functions.
1471 * blockframe.c (inside_main_scope, inside_entry_scope): New.
1473 * copying.awk: Filter formfeeds out of copying & warrantee.
1474 Make them available as `show copying' and `show warrantee' also.
1475 * main.c (print_gnu_advertisement): Advt `show' commands.
1477 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)
1479 * mach386-xdep.c: Even when cross-compiling, leave in the
1480 core-file reading code.
1481 * core.c (get_core_registers): Avoid coredump if no .reg section.
1483 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
1485 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
1486 This avoids coredumps under `set print object on' in value_headof
1487 (called erroneously by value_from_vtable_info) for `p &struct'
1488 or `p *struct'. From Peter Schauer.
1490 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
1492 * Makefile.in: Roll version to 4.1.2.
1493 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
1494 size from BFD (but, FIXME, we don't yet read external nlists's and
1495 convert them to internal nlists's before handling them -- we still
1496 assume they have the same size and alignment.) Use SET_NAMESTRING
1498 * exec.c (exec_file_command): Move dead coff-encapsulation code
1500 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.
1502 Fri Oct 4 22:30:06 1991 John Gilmore (gnu at cygnus.com)
1504 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
1505 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
1507 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
1509 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
1510 * mips-xdep.c (store_inferior_registers): Don't try to
1511 write the (pseudo) FP.
1512 * mipsread.c (parse_partial_symbols): Improved algorithm for
1513 setting pst->texthigh.
1515 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
1517 * doc/Makefile: make TEXINPUTS include . everywhere
1519 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
1521 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
1522 vestiges of typevectors, which were for symsegs and are no longer
1523 used. (From a question by Eliot Dresselhaus
1524 <dresselh@RFT30.nas.nasa.gov>).
1526 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
1528 * dbxread.c, coffread.c: static-ize functions that were
1529 gratuitiously external. (From Fred Fish.)
1531 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
1533 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
1534 until it is large enough.
1536 * dbxread.c (read_type): Handle error case slightly better.
1537 Make complaint message not C++-specific.
1539 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
1541 * infrun.c (wait_for_inferior): Fix step/next so that you only
1542 stop at the beginning of a new line. This fixes various problems
1543 with for loops, nested if-else's and switch statements.
1545 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
1547 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
1548 between symtabs and psymtabs become ordinary error()s.
1550 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
1551 properly, making "end pc" correct in shared lib psymtabs.
1552 (From Guy Harris <guy@auspex.com>.)
1554 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
1556 * dbxread.c: Enable, but soften, const_vol_complaint.
1557 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
1558 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
1559 should be file-scope, not global.
1560 (read_struct_type): Remove ancient multiple-inheritance warning.
1561 (read_range_type): Check base type, complain & patch if undefined.
1562 * stack.c (frame_info): Demangle the function name in `info stack'.
1563 (From Peter Schauer)
1565 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
1567 * eval.c (evaluate_subexp_for_address): Don't use
1568 TYPE_POINTER_TYPE directly (it might be zero if this type has
1569 never had a pointer created before); use lookup_pointer_type.
1570 * symtab.c (lookup_method_type): Arguments were swapped in all
1571 callers, so fix it here. I'm amazed this worked at all!
1573 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
1575 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
1576 "bss" rather than "data" symbols, but which still conflict.
1579 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
1580 * core.c (core_files_info): Shorten output.
1581 * exec.c (exec_files_info): Ditto.
1582 (build_section_table): Ignore zero-length sections.
1583 * language.c, printcmd.c: Lint.
1584 * language.h (get_frame_language): Declare.
1585 * saber.suppress: update.
1586 * stack.c (find_relative_frame): Remove complex code that was
1587 #if 0'd, stick with simple code. Lint.
1588 * saber.suppress: Update a bit.
1589 * symfile.c (add_symbol_file_command): Add "?" to question.
1590 * utils.c (parse_escape): Avoid \a due to bdead compilers.
1591 * value.h: Declare typedef_print.
1593 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
1596 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
1597 (Reported by Mark Peek <mark@imagen.com>.)
1599 * solib.c (solib_map_sections): Relocate all sections, even
1600 though only the text section's size is tracked. Mark ld_text
1601 for eventual elimination as we generalize to N sections.
1603 * infrun.c (wait_for_inferior): Don't check if the PC is in a
1604 call_dummy if we were stopped by a random signal that is being
1605 passed to the program. This produced wierd results when calling
1606 functions in the inferior and signals (e.g. SIGALRM) were in use.
1608 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
1610 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
1611 Bugfix from Paul Eggert <eggert@twinsun.com>.
1612 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
1613 * valprint.c (print_floating): Print 9 digits for IEEE floats.
1616 Mon Sep 23 15:50:07 1991 John Gilmore (gnu at cygnus.com)

1622 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
1626 * Makefile.in (VERSION): Set to 4.1.
1627 * language.c (set_language_command): Print useful help message,
1628 and restore the language string after giving help.
1629 * valprint.c (typedef_print): Print typedef in C or M2.
1630 * symtab.c (list_symbols): Use it.
1631 * main.c (main): Avoid any output before (gdb) prompt when -q.
1632 * language.c (set_language_command): Handle errors by restoring
1633 the language string to its current state (fix from A. Beers).
1634 * doc/gdbint.texinfo: Roll in information from README. Rearrange
1635 "how to install" and "how to print the doc" stuff so it drops
1637 * configure.in: Rename rtpc CPU to romp to match config.sub.
1638 * README, WHATS.NEW, TODO: Update for gdb-4.1.
1640 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
1642 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
1643 autoloading shared libs, copyright etc on GDB startup, clean up $_
1644 and $__ index refs, set/show listsize and related updates to list
1645 cmd. New host/target configs.
1647 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
1649 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
1650 from main Makefile.in version definition
1651 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
1653 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
1655 * doc/gdb.texinfo: merge new language-switching and lang-specific
1658 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
1660 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
1661 compilers (which may lack stddef.h).
1663 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
1665 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
1666 N_WARNING are the same except for the N_EXT bit, so just use their
1667 values alone, rather than OR-ing them with N_EXT.
1669 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
1671 * mipsread.c (parse_lines): Deal with negative extended line
1674 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
1675 global symbol conflicts.
1677 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
1679 * .gdbinit: Move 'set complaints' to top, so it runs even in
1680 case we aren't debugging GDB.
1681 * language.c (_initialize_language): Fix type check and range
1682 check documentation strings.
1683 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
1684 language.c can use it. (Though language.c should really not be
1685 handling warnings/errors the way it does, FIXME.)
1686 * symtab.c (lookup_primitive_type): const lint.
1688 Bugfix from Peter Schauer:
1689 * source.c (lines_to_list): Make signed, to avoid comparison
1690 going unsigned and complaining that -3 is too high for 21 lines.
1691 * stack.c (lines_to_list): Ditto.
1693 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
1695 * Makefile.in (HFILES): Add minimon.h.
1696 (VERSION): Roll version number to 4.0.95.
1697 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
1698 New rules for building distributions. Normal distribution
1699 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
1700 one level up from here; it calls make-proto-gdb.dir to build a
1701 directory `proto-gdb' which is an image of the release. The old
1702 `gdb.tar.Z' rule still works too.
1703 * config.sub, configure: Roll in latest from ..
1705 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
1707 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
1708 new-target, and new-config chapters; fix minor typos; come closer
1709 to usual GNU markup conventions for @file @samp @code @var.
1711 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
1713 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
1714 * mipsread.c (parse_partial_symbols): Enter the name of all
1715 structs/unions... into the psymtab so we can access them if the
1716 symtab is not read in.
1717 * mips-tdep.c: Remove some unneeded #includes.
1718 * xconfig/dec3100: Add HAVE_STRSTR.
1720 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
1722 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
1723 * c-exp.y, m2-exp.y: Lint.
1724 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
1725 * valprint.c (val_print_fields): Check for stub type.
1726 * mipsread.c (_initialize_mipsread): Avoid using
1727 builtin_type_void at initialize time.
1728 (mipscoff_symfile_read): use it now.
1730 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
1732 Merge multiple-language support, and partial Modula-2 support,
1733 from Andrew Beers <beers@cs.buffalo.edu>.
1735 * i387-tdep.c: New file, consolidates most 80387 support,
1736 and eliminates host dependency on double<->extended conversions.
1737 * i386-xdep.c, symm-xdep.c: Remove most 387 support.
1738 * xconfig/i386{sco,v,v-g,v32,v32-g}: Now need i387-tdep.o.
1740 * symfile.c (allocate_symtab): New fn, consolidates the work
1741 of allocating and initializing a new struct symtab. Set the
1742 language of the symtab based on its filename extension.
1743 * symfile.h: Declare it.
1744 * mipsread.c (new_symtab): Use it. Minor formatting changes.
1745 * dbxread.c (end_symtab): Use it.
1747 * mipsread.c (parse_symbol, case stParam and stProc): Add #if 0'd
1748 code for saving types of parameters with each function definition.
1749 * dbxread.c (define_symbol, function and parameter cases): Ditto.
1750 (read_dbx_symtab, case N_DEFD): Ignore.
1751 (read_enum_type): Recognize FALSE/TRUE enum as Modula-2 BOOLEAN.
1752 (read_range_type): Rename MAX_OF_TYPE to MAX_OF_C_TYPE, etc.
1753 #if 0 out its uses, though, since they set a dead value.
1754 * coffread.c (end_symtab): Use allocate_symtab.
1755 (process_coff_symbol): #if 0'd for functions and params as above.
1756 (read_enum_type): Recognize Modula-2 BOOLEAN.
1757 * symtab.c (add_param_to_type): #if 0'd function to add a
1758 parameter type to a function type's field list.
1760 * defs.h (local_hex_format, local_hex_string, *_custom): Add.
1761 * i386-xdep.c, pyr-tdep.c, pyr-xdep.c, remote-vx.c, solib.c,
1762 source.c, symfile.c, dbxread.c, breakpoint.c, core.c, exec.c,

1764 hex with local_hex_string for Modula-2 support.
1766 * breakpoint.c (breakpoint_cond_eval): Use new value_true to test
1767 breakpoint condition language-independently.
1769 * parse.c: New file with the common code remains of expread.y.
1770 * parser-defs.h: New file with common declarations from expread.y.

1829 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
1831 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
1832 entries are enclosed herein. Not all of these changes
1833 have been merged into the master GDB sources -- check the
1834 ChangeLog above here for the merge log.
1836 Mon Jun 3 17:05:45 EDT 1991
1838 m2-exp.y Created. Tested outside of GDB for a few days. Proper
1839 operators were added, C specific operators and tokens
1840 removed. yylex() revamped to some extent. Still things
1841 missing from the grammar, such as sets.
1842 Tested for two weeks in GDB v3.5.
1844 Tue Jun 11 17:23:48 EDT 1991
1846 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
1847 so they are built-in. Sort of a hack.
1849 Fri Jun 14 12:53:51 EDT 1991
1851 m2-exp.y Added range checking for numeric constants. Any numeric
1852 constant is assumed to be of builtin type INTEGER unless:
1853 (1) it is octal or hexadecimal, in which case it is a
1854 CARDINAL; (2) it is too big to fit into an INTEGER, in
1855 which case it is a CARDINAL.
1856 eval.c Added simple range checking for +, -, and * on integers.
1857 Doesn't work very well for *, since 6 * 1,000,000,000 =
1858 1,705,032,704, which fails the simple test of result >=
1859 first_operand, no matter in what order the operands are.
1861 Tue Jun 18 14:11:30 EDT 1991
1863 Broke the parser into parts, one containing the C grammar and the other
1864 containing code to be shared by all of the grammars.
1866 The following files no longer exist:
1871 The following files were added:
1873 c-exp.y (The C grammar)
1874 m2-exp.y (The Modula-2 grammar)
1875 parser-code.c (Code that is shared by the above grammar)
1879 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
1880 now necessary to use the Bison compiler compiler, since it
1881 will generate function/variable prefixes other than yy.
1883 Tue Jun 18 16:47:49 EDT 1991
1885 symtab.[ch] Added the external variable working_lang, than holds the
1886 value of the current working language.
1887 Added the ennumerated type language_mode, with the values
1888 language_auto and language_manual, the former meaning that
1889 GDB sets working_lang as needed, and the latter meaning
1890 that the value of working_lang is totally under user
1892 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
1893 REAL, BOOLEAN and CHAR. Also added the type codes
1894 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1895 utils.c Added set_language_command and show_language_command to
1896 implement the GDB support commands "set language" and
1898 expression.h A number of identifiers were added to the type exp_opcode
1899 to facilitate Modula-2 builtin functions, integer
1900 division, and array indexing.
1902 Wed Jun 19 13:25:58 EDT 1991
1904 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
1905 if the language specified by working_lang requires the use
1906 of strict typing of expressions. Eventually, even this
1907 will be able to be changed by the user.
1908 Added the macro RANGE_CHECK, which evaluates to non-zero
1909 if the language specified by working_lang requires the
1910 checking of a value against the domain of its type.
1911 Eventually, even this will be able to be changed by the
1913 language.[ch] Predicates involving types (simple_type, ordered_type,
1914 same_type, integral_type, numeric_type, character_type,
1915 boolean_type, float_type) are added. These predicates are
1916 based on the current value of working_lang, and are handy
1919 Wed Jun 19 15:39:34 EDT 1991
1921 eval.c Added the function type_array_rank which computes the rank
1923 valarith.c Added the funtion value_bool, which when given a integer
1924 value.h value (ie. struct value *) as an argument, it returns a
1925 boolean value (ie. struct value *) true if that integer
1926 is non-zero, and a boolean value false otherwise.
1927 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
1928 will print out properly.
1930 Wed Jun 19 16:36:34 EDT 1991
1932 valops.c Added the function value_capitalize, which returns it
1933 value.h argument capitalized if its argument is a lowercase
1934 letter, or the argument unchanged if its argument is not a
1936 valarith.c Added the function range_check_p, which returns non-zero
1937 value.h if its value argument is between the integral bounds upper
1939 Added the function range_check_enum_p, which makes sure
1940 that its value argument is a valid member of the domain of
1942 Added the function range_check_range_p, which makes sure
1943 its value argument lies between the upper and lower bounds
1944 of its type argument, which must be a ranged type.
1945 Added the function check_array_index, which range and type
1946 checks an index of an array.
1947 Added the function value_multi_subscript, which computes
1948 array[idx1,idx2...idxN], given a value array and an array
1949 of values representing indicies.
1950 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
1951 unpack_long to work with TYPE_CODE_BOOL and
1954 Wed Jun 19 18:04:08 EDT 1991
1956 symtab.c Stored pervasive types in a structure and make
1957 lookup_pervasive_type() a lookup function that was based
1958 on working_lang. If lookup_pervasive_type() returned
1959 non-zero, then that value was returned (a fix, since
1960 before it simply wouldn't return the pervasive type.)
1961 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
1962 non-zero if the language specified by working_lang means
1963 "conversion" when it says "cast".
1964 valops.c Added the function value_real_cast(), which performs a
1965 value.h *cast*, not a *conversion*, which is what value_cast()
1966 does when it can. In particular,
1967 value_cast(<float_type>,4) = 4.0, while
1968 value_real_cast(<float_type>,4) = some mess.
1969 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
1970 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
1971 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
1972 and MIN on integral types. *NOTE*: These are currently
1973 hardcoded to work only if there are 8 bits per storage
1975 eval.c Made logical functions call value_bool to return a
1976 properly typed boolean value, based on working_lang.
1978 Thu Jun 20 11:55:27 EDT 1991
1980 valprint.c Types now print out in a Modula-2 fashion. This works for
1981 the cases when the type is printed out step-by-step, that
1982 is, it doesn't work when the name of a structured type
1983 (which includes the keyword "struct", etc.) is simply
1985 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
1986 since type specifications in C and Modula-2 are very
1987 different. The C printing of a type is very recursive,
1988 whereas in Modula-2 it is generally very simple. C has
1989 type prefixes and suffixes, which have no real analogue in
1990 Modula-2. Maybe type_print() should call a language
1991 specific type printer. This is also advantageous if we
1992 compile GDB to exclude some of the languages. We'll just
1993 leave those functions out.
1995 Thu Jun 20 16:57:10 EDT 1991
1997 dbxread.c When reading the complete symbol table in (via
1998 psymtab_to_symtab()), the number and types of function
1999 arguments are added to a function type. define_symbol()
2000 calls add_param_to_type() to accomplish this.
2001 Assumption: when we come across a function definition
2002 (N_FUN symbol with an 'f' or 'F' in the name), its
2003 arguments will appear before another function definition.
2004 When a function is found, a pointer to its type is placed
2005 in the global in_function_type. Changes that
2006 add_param_to_type() makes are to this global.
2007 valprint.c The type of a function now includes (for Modula-2) the
2008 types of its parameters.
2009 eval.c Type checking and a check for the proper number of
2010 arguments is now done for function calls. Not sure of the
2011 impact this has on C++ member function yet.
2013 Thu Jun 20 19:58:48 EDT 1991
2015 valprint.c Rewrote the type printer. Broke it into two language
2016 specific parts, adding the functions type_print_m2() and
2018 An unfortunate consequence is this: if you debugging a C
2019 program in Modula-2 mode (why?), info types does not work
2020 well with regular expressions, since the types are printed
2021 out in Modula-2 terminology, but stored in C terminology.
2022 language.[ch] Added the functions new_type_last(), type_keyword(), and
2023 type_sep() to aid in the printing of typedefs.
2024 symtab.c Made the printing of typedefs as language independent as
2025 possible through calls to new_type_last(), type_keyword(),
2028 Fri Jun 21 11:50:26 EDT 1991
2030 dbxread.c Check all incoming ennumerated types. If it looks like
2031 Modula-2's BOOLEAN type, then change the type_code of the
2032 type to TYPE_CODE_BOOL so we can process it as a boolean
2034 valprint.c Replaced some of the 0x%x with calls to sprintf and
2035 hexformat() in val_print().
2036 language.[ch] Added the function hex_to_string(), which converts its
2037 integral argument to a hexadecimal number (format is
2038 language based) and returns the result as a string.
2040 Mon Jun 24 12:25:07 EDT 1991
2042 valprint.c Some functions call type_print_1() directly, instead of
2043 value.h using type_print(), so they can specify where (column) to
2044 print things. Since type_print() takes care of language
2045 dependence, that needs to be called first. Added a
2046 parameter depth to type_print() (so it is now like
2047 type_print_1). Changed type_print to type_print_at, and
2048 made type_print a macro that passes a depth argument of
2050 symmisc.c Changed all calls to type_print_1 to calls to
2052 Makefile.dist Made it possible to build GDB for a specific set of
2053 depend languages. Do this by passing a definition for the macro
2054 LANGS to make. LANGS should be a string containing a
2055 space-separated list of language names (ie. LANGS="c m2").
2056 The default is to build all languages. Note that grammar
2057 files must follow the naming convention of <lang>-exp.y.
2058 gdb.lang This holds the current value of the LANGS macro. It is
2059 examined every time make is called, and is updated if
2061 eval.c Added #ifdef _LANG_<lang> to these files.
2062 expread.c Still need to add them to dbxread.c and coffread.c.
2070 Mon Jun 24 16:33:11 EDT 1991
2072 language.[ch] Added the functions hexformat_pre() and
2073 hex_to_string_pre(), which take a prefix argument to
2074 include in the format string. Thus, hexformat_pre("08") will
2075 return "0x08x" (if the working language is language_c).
2076 Made hexformat() and hex_to_string() calls to the above
2077 with "" as the prefix argument.
2079 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
2080 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
2081 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
2082 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
2083 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
2084 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
2085 valprint.c, vax-pinsn.c
2087 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
2088 calls to hexformat() and hex_to_string(). Format strings without
2089 the leading "0x" were ignored.
2091 depend Updated to take the above into account.
2094 Tue Jun 25 15:27:18 EDT 1991
2096 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
2097 and type_check_t to keep track of the current state of
2098 range and type checking.
2099 main.c Added the variables range_mode, range_check, type_mode,
2100 and type_check to record the current state of range and
2101 type checking. Added initialization code to main().
2102 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
2103 the above variables.
2106 Tue Jun 25 17:57:08 EDT 1991
2108 dbxread.c process_one_symbol() updates the variable (enum language)
2109 source_lang based on the extension of the filename
2110 contained in the N_SO sybmol that started this symtab.
2111 When end_symtab() is called, the value of source_lang is
2112 put into the language field.
2113 stack.c select_frame() sets working_lang (and possibly type_check
2114 and range_check) to the language field of the symtab
2115 associated with the frame that is selected if working_mode
2116 is language_auto. If working_mode is language_manual, a
2117 warning is printed and working_lang is not set.
2118 language.c Added the function set_type_range(), which sets the value of
2119 type_check and range_check (if their modes call for
2120 automatic setting) based on the current value of
2121 working_lang. A non-zero argument will cause the current
2122 settings to be output.
2125 Wed Jun 26 14:51:40 EDT 1991
2127 eval.c Added range checks on assignment.
2128 m2-exp.y Added the grammar for sets to the language. Currently,
2129 these do not do anything except print an error message.
2131 Wed Jun 26 17:01:04 EDT 1991
2133 m2-exp.y Added the ability for parse_number() to parse negative
2134 numbers. A global flag is set upon encountering a unary
2135 minus. This was done to make, for example, 1 parse as a
2136 CARDINAL, and not as an integer, per Wirth's examples in
2137 Programming in Modula-2 ed.4.
2138 valprint.c Added support for "set radix 2" by then setting
2139 output_format to 't'.
2140 eval.c Implemented range checking on subrange types. Added calls
2141 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
2142 Implemented MIN and MAX for ennumerated types. The
2143 minimum value of an ennumerated type is defined by Wirth
2144 as the first identifier, and the maximum as the last.
2145 m2-exp.y Made octal numbers ending with "B" be characters and those
2146 ending with "C" be numbers, per Wirth's book. (p. 34)
2148 Thu Jun 27 14:11:52 EDT 1991
2150 stack.c select_frame() now only sets working_lang, it does not
2151 notify the user. If working_mode is language_manual, then
2152 a warning is issued once.
2153 main.c At the end of each call to execute_command(), working_lang
2154 is checked against the local static (enum language)
2155 current. If they differ and working_mode is
2156 language_auto, the new settings of language, type and
2157 range checking are printed out.
2158 stack.c Modified frame_info() to include the language of the
2159 current frame in the output of "info frame".
2160 language.[ch] Added the function language_str() which returns the name
2161 of the current language.
2163 Fri Jun 28 15:33:14 EDT 1991
2165 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
2166 the language. INCL and DECL currently cause an error,
2167 since sets are not implemented yet. INC and DEC are
2168 implemented as PREINCREMENT/PREDECREMENT with one
2169 argument, and as ASSIGN_MODIFY with two arguments.
2170 eval.c Added type checking to the above cases.
2171 value.h Added not_lval_constant to the lval_type ennumerated type.
2172 not_lval_constant means that the value is a constant
2173 value; that is 3 or 'a' or TRUE, not as in a constant
2174 identifier. This is used to help coerce numbers such as 3
2175 to either signed or unsigned numbers.
2176 valops.c Added the function value_coerce_constants() which coerces
2177 constant integers as following: if one is a constant and
2178 the other is not, the constant's type is set to the type
2179 of the other argument. If both are constants and one is
2180 signed, the other is converted to a signed constant.
2182 Sat Jun 29 17:26:29 EDT 1991
2184 valarith.c Added a better range checker. It now checks range
2185 (successfully) on integral operations [+-] (signed and
2186 unsigned) for any C sized type. Still does not work well
2187 for multiplication.)
2188 int_in_size() returns an integer that is coerced to fit into
2189 specified number of bytes.
2191 Mon Jul 1 13:04:14 EDT 1991
2193 language.[ch] Added the function binop_result_type(), which returns the
2194 builtin (struct type *) type that would be the result of a
2195 binop on the two values V1 and V2.
2197 Wed Jul 3 19:22:53 EDT 1991
2199 source.c Extended source_info() to include the source language in
2200 the output from "info source".
2202 Fri Jul 5 13:48:52 EDT 1991
2204 utils.c Moved the support functions for the GDB set/show commands
2205 dealing with language into language.c.
2206 language.c Added the function language_info(), which displays info
2207 about the current working language, type and range check
2208 settings. Called via the GDB command "info language".
2209 Added an initialization routine _initialize_language(),
2210 that sets defaults for the language, type and range
2211 variables and sets up the new GDB commands.
2212 main.c Language setup moved to language.c.
2215 Mon Jul 8 10:10:22 EDT 1991
2217 valarith.c Debugged the range checker for arithmetic. Still does not
2218 work for multiplication very well.
2220 Mon Jul 8 12:40:37 EDT 1991
2222 language.[ch] Added the function value_true() which returns non-zero if
2223 its argument represents a boolean true value.
2224 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
2225 check the truth of an expression.
2227 Thu Jul 11 12:51:34 EDT 1991
2229 language.[ch] Added the predicate structured_type(), which returns
2230 non-zero if the argument is a structured type.
2231 Added the predicate pointer_type(), which returns non-zero
2232 if the argument is a pointer type.
2233 eval.c Added the ability to do addition and substraction on
2234 pointers and integers. This case simply bypasses the
2237 Thu Jul 11 14:41:42 EDT 1991
2240 Added the symbol N_DEFD (0x4a) which is a definition
2241 module dependency that is used by the GNU Modula-2
2242 compiler and the linker. It is not important to GDB,
2243 except that [dbx|coff|mips]read.c should ignore these
2246 Fri Jul 12 16:07:00 EDT 1991
2248 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
2249 0 in val_print(). Also added statements to the else part
2250 to coerce type (argument to val_print) to a pointer type
2251 if it is an "array of unspecified length".
2252 valops.c Added the function value_m2_string(), which returns a
2253 (value) value which is a constant string, whose type is
2254 (ARRAY [0..n] OF CHAR). The length field of the type
2255 structure is set to zero, so it will be interpreted as an
2256 "array of unspecified length".
2257 stack.c Moved the language/frame mismatch check to
2258 main.c:execute_command().
2259 main.c The working language is recorded each time
2260 execute_command() is executed. If working lang has
2261 changed during its execution, then the new
2262 language/type/range info is printed out for the user. If
2263 the working language does not match the language of the
2264 frame, a warning is issued.
2266 Sat Jul 13 16:16:39 EDT 1991
2268 eval.c Moved all the type-checking stuff for operators to
2269 language.[ch] language.c. This is so we can keep language-specific
2270 stuff (like for what type operators are defined) in
2272 language.[ch] Added the function binop_type_check(), which checks to see
2273 if its two (value) arguments are type-compatible with its
2274 opcode argument. The opcode should represent an operation
2275 involving an operator. Also added the macro function
2276 unop_type_check, which calls binop_type_check with a
2277 NULL second argument.
2278 expprint.c Added Modula-2 operators to the op_print_tab, so info
2279 expression.h break works correctly. Also added "op_string", which
2280 returns the string corresponding to the (enum exp_opcode)
2281 opcode that is its argument.
2284 Sat Jul 13 18:26:18 EDT 1991
2286 coffread.c Added code to record the type of function arguments with
2287 each paricular function. Code is very similar to that
2289 dbxread.c Moved add_param_to_type() to symtab.c
2290 symtab.[ch] Added function add_param_to_type() from dbxread.c
2292 *** NOTE: The above additions have not been tested.
2294 Mon Jul 15 12:50:47 EDT 1991
2296 langauge.[ch] Added the functions type_error and range_error, which work
2297 like error() except if the type/range mode is set to
2298 *_mode_warn, then they do not do a return_to_top_level(),
2299 but merely print a warning.
2300 Also changed [set|show]_[type|range]_command() to support
2301 the new "warn" feature.
2303 Thu Jul 18 17:50:54 EDT 1991
2305 mipsread.c Added code to record the type of function arguments with
2306 each particular function. Code is very similar to that
2309 *** NOTE: The above additions have not been tested.
2311 Fri Jul 19 11:19:10 EDT 1991
2313 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
2314 UMIN_OF_SIZE, which when given a size of a numeric type,
2315 return the maximum and minimum value it can hold. UMAX...
2316 and UMIN... return the result for unsigned types.
2317 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
2318 struct types. They call above macros.
2319 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
2320 avoid a name conlict with the above.
2321 c-exp.y Added range checking on numeric constants in
2322 parse_number() for completeness.
2323 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
2324 return 0 if working_lang is not language_c.
2326 Thu Aug 8 14:17:22 EDT 1991
2330 breakpoint.c Documentation strings of some commands changed to
2331 eliminate the references to the C language where
2334 Tue Aug 13 15:48:03 EDT 1991
2336 m2-exp.y Added qualified identifiers to the grammar. The semantics
2337 are slightly different from those of the GDB operator ::
2339 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
2340 type_exp, where type_exp is any valid type expression.
2342 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
2343 printcmd.c Modified ptype_command() so it actually parses the input
2344 (necessary for type expressions with scope qualifiers).
2345 Added the function ptype_eval() which expects an
2346 expression composed of one OP_TYPE element.
2347 *.[ch] Replaced all occurences of parse_c_expression with
2349 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
2351 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
2353 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
2355 Small fixes from Peter Schauer:
2357 * infrun.c (child_attach): Lint.
2358 * solib.c (find_solib): Handle shared libs version 2.
2360 Small fixes from David Wood:
2362 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
2366 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
2367 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
2369 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
2370 chars_per_line is at maximum (user typed `set width 0'). Fix
2371 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
2373 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
2375 * coredep.c: include ptrace.h where necessary.
2376 * mipsread.c(parse_lines): fix unsigned char problem that was
2377 messing up line numbers on SGI's and possibly other MIPS based
2379 * infrun.c (child_create_inferior): use better test to check
2380 return val from setpgrp().
2381 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
2382 for sgi/irix support.
2384 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
2386 * mipsread.c (parse_symbol): Put non-static procedures
2387 in the global block.
2389 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
2391 Patch together `text_start' and `text_end' for 29K port.
2393 * exec.c (exec_command): If NEED_TEXT_START_END, define the
2394 variables and set them based on the exec file.
2395 * am29k-tdep.c: declare text_start.
2396 * valops.c (call_function_by_hand): declare text_end.
2398 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
2399 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
2400 because machines that do this will also have to know to
2401 set NEED_TEXT_START_END. Besides, it was a redundant way to
2403 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
2404 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
2405 NEED_TEXT_START_END.
2407 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
2409 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
2411 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
2412 Pass MUNCH_DEFINE to munch whenever we run it.
2413 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
2414 format string; use 0x%x instead.
2415 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
2416 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.

2424 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
2425 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
2426 Merge target arm case with other "easy" cases. Add target
2427 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
2428 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
2430 * minimon.h, remote-adapt.c, remote-mm.c: Add.
2431 * munch: Cope with RT/PC putting fns in data segment.
2432 Restore ability to override `nm' by specifying MUNCH_NM.
2433 * xconfig/rtbsd, xconfig/ultra3: New host systems.
2434 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
2435 and remote-adapt. Remove encapsulated coff #define's (the
2436 support should go in BFD, and gdb shouldn't know or care).
2437 * tconfig/a29k-kern: Same, but for remote kernel debugging.
2438 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
2439 * tm-29k.h: Update BADMAG (though it should go away).
2440 Allow the register definitions to be overridden in another
2441 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
2442 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
2443 DUMMY_SAVE_GR96, for handling kernel calling conventions
2444 that use GR64+ rather than GR96+.
2445 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
2446 remote debugging of Ultra3 kernel. Includes tm-29k.h and
2447 overrides various things.
2449 * remote-mm.c (mm_attach, mm_wait): Handle attach like
2450 child_attach does, making a clean stop in the newly attached
2452 * remote-eb.c: Lint.
2454 * coffread.c: Make coffread independent of any particular
2455 variant of COFF. Avoid #include-ing any particular one except
2456 internalcoff.h. BFD now passes key values for symbol reading
2457 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
2458 and the symbol masks and shifts); use them.
2459 Remove obsolete end_of_text_addr.
2461 * exec.c: Remove unused include files.
2463 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
2465 * Makefile.in (documentation targets): Pass $(M4).
2466 Bugfix from eggert@twinsun.com (Paul Eggert).
2468 * stack.c (down_silently_command): Check for stack existence.
2470 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
2472 * Makefile.in (VERSION): Update to 4.0.3.
2474 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
2476 * core.c (core_file_command): Print frame at coredump with
2477 its level number, by calling print_stack_frame.
2478 * frame.h: Add selected_frame_level, print_stack_frame.
2479 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
2480 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
2481 Change print_sel_frame and print_selected_frame callers to
2484 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
2485 * symfile.c (free_named_symtabs): Ditto.
2486 * main.c (main): wrap_here needs an arg.
2487 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
2488 (solib_add): Avoid noise.
2489 (solib_create_inferior_hook): Lint.
2490 (sharedlibrary_command): Move dont_repeat to here.
2491 * utils.c (error): Call wrap_here to force buffered output.
2493 Small patches from Peter Schauer:
2495 * coffread.c (start_symtab): Free any existing line_vector before
2497 (read_coff_symtab): Ditto for type_vector.
2499 * source.c (lines_to_list): New variable, replacing function.
2500 (all uses): Use as variable.
2501 (_initialize_source): Add 'set listsize' and 'show listsize'.
2502 * utils.c (lines_to_list): Remove function.
2503 * stack.c (print_frame_info): Use as variable.
2504 * defs.h (lines_to_list): Remove declaration.
2506 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2508 * breakpoint.c (insert_breakpoints): Restore warning about
2509 the program might be running in another process, but only for
2510 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
2511 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
2513 * utils.c (error): if error_pre_print is set, print the string
2515 * main.c (main, print_gnu_advertisement, print_gdb_version):
2516 Reformat legalese so it always prints, but acts as an "I'm here"
2517 message while symbols are being read. If any errors occur,
2518 print a few newlines to set off the message and start it at the
2519 left margin. Remove mention of "help" command, and don't yak
2520 about symbol reading.
2521 (catch_errors): Error string is now printed first in case of
2523 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
2524 suggest the "help" command.
2526 * Makefile.in (VERSION): Set to 4.0.2.
2528 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
2530 * .gdbinit: Remove useless "rr" command. Set complaints
2531 to 1 for people debugging gdb.
2533 * breakpoint.c, remote-vx.c: Reword strings printed by
2534 catch_errors callers.
2536 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
2538 * WHATS.NEW: "history write -> history save". Doc "write on/off".
2539 (Fix from kenc@viewlogic.com.)
2541 Fix some infrastructure to be able to cope with host and target
2542 machines with different sized basic types (ints, ptrs, etc).
2543 (Idea from pierre@la.tce.com (Pierre Willard).)
2545 * values.c (value_from_longest): Rename from value_from_long.
2546 Handle pointer types as well as integers, so that targets with
2547 different pointer sizes from the host can be accomodated.
2548 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
2549 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
2550 uses of value_from_long to value_from_longest.
2551 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
2552 the correct pointer type to value_from_long{est}.
2554 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
2556 * remote-vx.c: Remove obsolete code for calling functions via
2557 vxworks kludge interface (it referenced value_from_long).
2559 * valops.c (value_string): Find malloc with lookup_misc_func, not
2562 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2564 Make writing to files work properly. (Fixes to BFD are also needed.)
2566 * core.c (core_open): Open file ourselves, read or r/w, depending on
2567 write_files. Use bfd_fdopenr.
2568 * gdbcore.h (write_files): New variable.
2569 * exec.c (write_files): Define variable, add set&show for it.
2570 (exec_file_command): Use write_files to open for read or r/write.
2572 Make shared library reading happen automatically. These changes
2573 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
2575 * inferior.h (stop_soon_quietly): Add to exported variables.
2576 * infrun.c (child_create_inferior): call solib hook, if defined.
2577 (child_attach): call solib hook, if defined.
2578 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
2579 (find_solib): Use lookup_misc_func rather than hand-rolled.
2580 (symbol_add_stub): New stub for catch_errors.
2581 (solib_add): Avoid output if !from_tty. Catch errors rather
2582 than just calling symbol_file_add and bombing.
2583 (solib_create_inferior_hook): Interface with the target process
2584 to let it read and alloc shared libs, then figure out what it did.
2586 * core.c (validate_files): Fix typo, soften warning.
2587 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
2589 * utils.c (fputs_demangled): Avoid duplicate printing if
2590 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
2592 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
2593 (Fix from pierre@la.tce.com (Pierre Willard).)
2595 * main.c (catch_errors): Change argument to a char * from an int,
2596 since a char * can point to a struct full of glop, but an int
2597 is not guaranteed to be able to hold a pointer.
2598 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
2599 breakpoint_re_set_one, breakpoint_re_set): Adapt.
2600 * core.c (core_open, solib_add_stub): Adapt.
2601 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
2603 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2605 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
2606 by adding .NOEXPORT target.
2608 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2612 * Makefile.in (VERSION): Roll to 4.0.
2613 (gdb.tar.Z): Make refcard.ps as well, for shipment.
2615 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2617 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
2620 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
2623 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
2625 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
2626 reflect above name change
2628 * WHATS.NEW: correct pointer to refcard.
2630 * doc/gdb.texinfo: update New Features, Installing
2632 * doc/gdbint.texinfo: add short description of configure +template
2634 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2636 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
2638 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
2640 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
2641 tar file, add dependencies for referenced doc files.
2643 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
2645 * coffread.c, symfile.c, stack.c: saberized.
2647 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2649 * doc/refcard.tex: permuted Essential Commands sec
2651 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
2653 set/show symbol-reloading
2654 default set complaints 0
2656 RET-repeat disabled after prompted long displays
2657 processID (attach) interpretation of 2nd GDB cmdline arg
2659 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
2661 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
2662 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
2663 breakpoint.c, main.c: lint.
2665 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2667 Install new configuration scheme for GDB and friends.
2669 * config.sub: Translate ordinary names to three-part names.
2670 * configure: Use three-part names internally.
2671 * configure.in: Translate three-part names to filenames.
2673 * README, WHATS.NEW: Update for gdb-4.0.
2674 * Makefile.in: Roll VERSION to 3.99.
2676 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
2678 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
2679 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
2680 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
2681 to single structures rather than arrays; when passing
2682 their address, use &. This avoids trouble with bdead compilers.
2683 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
2684 instead. This avoids portability headaches.
2685 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
2687 * source.c (open_source_file): Avoid ANSI const bdeath by
2688 skipping declaration and then casting result value.
2689 * tm-hp300bsd.h: Clarify comment.
2690 * utils.c (strstr): Result is const char *; ANSI bdeath.
2691 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
2692 since system include file defines it differently from "defs.h",
2693 though the two are equivalent for our purposes.
2694 * tconfig/hp300bsd: Add m68k-tdep.o.
2696 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
2698 * tconfig/sun*4: Remove warnings about system assembler.
2700 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2702 * mcheck.c: Avoid warning about undeclared abort fn.
2703 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
2704 it causes recursive calls to error() when used in cleanups.
2705 To do so requires that we make it a function, so we do.
2706 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
2707 * utils.c (do_cleanups): Remove the current cleanup from the
2708 chain *before* calling it, in case error() is called from it.
2709 The result won't be pretty, but won't be an infinite loop either.
2711 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
2713 * dbxread.c (read_struct_type): Grok anon structs for C++.
2714 (vb_name, vptr_name): Null terminate these strings.
2716 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2718 Minor bug fixes from BSD Net2 gdb:
2720 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
2721 returns 0, there is no previous frame.
2722 * breakpoint.c (commands_command): If !from_tty, don't call
2723 input_from_terminal_p().
2724 * dbxread.c (record_misc_function): Speed up slightly.
2725 (compare_psymbols): Ditto.
2726 * infcmd.c (do_registers_info): Take a second argument to
2727 determine whether to print float registers. "info registers"
2728 does not do so anymore. "info all-registers" does, now.
2729 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
2731 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
2732 * inflow.c (initialize_inflow): Set tflags_ours correctly.
2736 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
2737 executing_breakpoint_commands if we are interrupted by error.
2738 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
2739 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
2740 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
2741 catch_errors() so we can setup the frame regardless of whether
2742 the shared libs work.
2743 * ieee-float.c (double_to_ieee_extended): Get exponent from
2744 right place in little-endian systems. From John Carey.
2746 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2748 * main.c: Remove unused terminating_signals and catch_termination().
2749 (long_options): Terminate with a zero element.
2750 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
2751 (gdb_readline): Make call-compatible with readline.
2752 (init_signals): Improve comments re vfork vs. signal.
2754 * utils.c (prompt_for_continue): Use new gdb_readline().
2755 If we prompt for continuation, we don't let CR repeat the previous
2756 command, once we get back to a prompt. It's too easy to keep
2757 hitting CR, expecting "--more--" prompts, and have some long
2758 command start repeating on you.
2760 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2762 * blockframe.c (frameless_look_for_prologue): Speed up by
2763 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
2764 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
2765 Define two variants, one faster.
2766 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
2767 and return zero, rather than giving an error.
2768 (setup_arbitrary_frame): Initialize the PC in the new frame.
2769 (skip_prologue): Add a second arg saying whether we're just
2770 checking for a frameless function or not.
2772 * core.c (core_open, core_close, core_xfer_memory): Move
2773 section table pointers and bfd* into the target_ops.
2774 (core_open): Allow errors in shared lib reading, etc.
2775 (core_files_info): Describe shared library sections.
2777 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
2778 exec_files_info, set_section_command): Move section table
2779 pointers and bfd* into the target_ops.
2780 (add_to_section_table): Add BFD to section table.
2782 * target.c (target_xfer_memory, target_info): Pass target to
2783 xfer_memory and target_info functions.
2786 * gdbcore.h: Move struct section_table.
2787 * target.h: New home of struct section_table.
2789 * solib.c (solib_add): New argument is the target_ops whose
2790 section list is to be added to, if any. Reallocate the
2791 sections in that target to add any that come from shared libs.
2792 (throughout) so_sections renamed to sections.
2793 (solib_xfer_memory): Deleted.
2794 * tm-sunos.h (SOLIB_ADD): Add target argument.
2795 (SOLIB_XFER_MEMORY): Delete.
2797 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2798 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
2799 from target_ops. It's the same on all targets. Add two section
2800 pointers to target_ops.
2802 * stack.c (find_relative_frame): Dump ancient algorithm for
2803 "down", just use handy "next" pointers.
2804 (frame_command): Don't error if there is no stack; let user
2807 * inflow.c (new_tty_prefork, new_tty): New prefork routine
2808 modifies static state in the parent process; new_tty itself
2809 runs in the child and modifies the child's file descriptors
2810 to match the saved static state.
2811 * infrun.c (child_create_inferior): Call new_tty_prefork,
2814 * infptrace.c (child_xfer_memory): Add ignored target arg.
2815 * remote-eb.c (eb_xfer_inferior_memory): ''
2816 * remote-nindy.c (nindy_xfer_inferior_memory): ''
2817 * remote-vx.c (vx_xfer_memory): ''
2818 * remote.c (remote_xfer_memory): ''. Rename from
2819 remote_xfer_inferior_memory.
2821 * main.c (main): Only try to attach "corefile" argument if
2822 it starts with a digit.
2824 * symfile.c (symbol_reloading): New "set/show" variable.
2825 (symbol_file_add): Shorten message about symbol reading.
2826 (add_symbol_file_command): Merge with add_syms_addr_command,
2827 since this should work on all targets now.
2828 (stop_whining): Default to zero, to shut up complaints
2829 about bad symbol tables on many systems.
2830 (free_named_symtabs): Just exit unless symbol_reloading.
2832 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
2833 and add comment explaining shared library screw.
2835 * source.c: #if defined => #ifdef.
2837 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2839 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
2841 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2843 * doc/rdl-apps.texinfo: provide default readline-appendix finder
2844 (doc/Makefile knows how to make one for local config)
2846 * Makefile.in: use doc/Makefile for doc targets
2848 * doc/Makefile: GDB documentation now has its own Makefile
2849 doc/refcard.tex: renamed from "gdbrc.tex"
2850 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
2851 doc/gdbint.texinfo: add markup in "Cleanups" chapter
2854 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2856 * values.c (baseclass_addr): When reading target memory, use the
2857 length of the basetype, not the upper type. We've only malloc'd
2858 enough space for the basetype, leading to errors in free().
2860 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
2861 ends up as a function specially, since we know the actual type of
2862 the pointed-to address. This (somewhat) fixes display of
2863 expressions that include misc_function_vector names. Try `cond 1
2864 !strcmp("a","b")' then `i b'.
2866 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
2867 The child can be proceeded from inside wait_for_inferior in
2868 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
2869 getting skipped in that case.
2871 * expprint.c (print_subexp): Use filtered output, since the
2872 subroutines we call use it, otherwise the output is horribly
2873 mangled, since output of wrappable stuff comes out late.
2875 * Makefile.in: Bump VERSION to 3.98.1
2877 * infrun.c (child_create_process): Use execlp to find the
2878 shell to exec our target program. This requires some fiddling
2879 with `environ' since there is no execlpe().
2881 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2883 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
2884 Minor rearrangement of refcard permits two new make targets--
2885 gdbrc.dvi DVI output for refcard, using CM fonts
2886 gdbrc.ps PostScript refcard, using PS fonts
2888 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2892 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
2893 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
2895 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2897 * doc/gdb.texinfo: last changes for release.
2898 Minor typo and formatting fixes; incorporated most fixes remaining from
2899 filed mail commenting on earlier drafts.
2901 Added warnings: pipes don't work in run command;
2902 conditions are converse of assertions;
2903 step over fn without debug info goes to next fn;
2904 vars may have "wrong" values near fn entrance, exit
2906 Added example from Kingston on printing repeated nonadjacent values
2908 Added explicit mention that in Emacs gdb mode C-c and C-z are like
2909 shell mode for signals
2911 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
2912 doesn't sound so much like its parent "Stopping and Continuing"; also
2913 moved entries on continue to top of section, so they don't get lost.
2915 Improved installation directions in appendix, added manual formatting
2918 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2920 * configure.in: Remove xm.h and tm.h even if we aren't linking
2921 new ones, so "./configure sun4; ./configure none" does the right
2922 thing. Assume that alldeps.mak and depend are already built in
2923 srcdir, and avoid running "make" (particularly "make depend",
2924 which involves "gcc") from inside configure. Build Makefile
2925 directly rather than building Makefile.conf first.
2926 * configure: Regenerate with above changes.
2927 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
2928 to 3.98. Revise gdb.tar.Z procedure to produce a file
2929 called gdb-$(VERSION).tar.Z but which unpacks into a
2930 directory called "gdb". Move non-source files out of
2931 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
2932 (depend): Don't try to do "gcc expread.y".
2933 (expread.o): Update dependencies by hand.
2935 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2938 Fixed a variety of small typos that prevented info from formatting
2939 cleanly; altered too-long heading for GPL Appendix, as discussed
2940 w/RMS; Changed date on cover to July 91.
2942 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2945 (1) Applied some fixes due to comments from Larry Breed (easier ones
2946 through chapsec 5.2)
2947 (2) Eliminated use of @footnote---had my doubts about it anyways, and
2948 it's broken in latest texinfo
2949 (3) Introduced *some* use of [] for optional arguments, where
2950 explanation is not simpler by listing cmd w arg and cmd w/out arg
2951 separately. Still not using @deffn.
2952 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
2953 couple of headings are too long. Need patches to texinfo or revision
2956 * Partial update to README (which still needs work for this
2957 release!): (1) use of configure corrected for new script,
2958 (2) "make gdb.dvi" and "make gdb.info" mentioned.
2960 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
2962 * symtab.c (lookup_symbol): Don't complain right off about
2963 no debug symbols; use the misc function vector first.
2964 (list_symbols): Use misc function vector to find symbols
2965 that don't have debug info, and print them.
2966 (find_pc_symtab): Temporarily avoid fatal() when psymtab
2967 PC range doesn't match symtab PC range, as it does on the
2968 MIPS because our symtab reading isn't perfect.
2970 * dbxread.c (dbx_symfile_read): Make warning about
2971 "no debug symbols" slightly nicer.
2973 * source.c (select_source_symtab): If "main" symbol exists,
2974 but decode_line_spec can't find line info, don't just return
2975 a zero; try other source symtabs or give an error.
2977 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
2978 their low addresses first, then rip through fixing high addrs.
2980 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
2981 <runene@ifi.uio.no>.
2982 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
2984 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2986 * Minor, mostly mechanical, cleanup of doc subdir for clean
2987 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
2988 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
2990 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
2992 Mostly MIPS and general symbol-reading fixups.
2994 * doc/gdbint.texinfo: Add documentation on symbol-reading
2997 * mipsread.c: Remove kludges around #include "ecoff.h".
2998 Remove redefinitions of a_magic, etc, no longer used.
2999 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
3000 Fix global overview comments to match symfile.c protocol.
3001 (mipscoff_new_init): Eliminate cur_hdr if we have one.
3002 (mipscoff_symfile_read): Eliminate unused code. Avoid
3003 sorting all the symtabs, when all we have read here is psymtabs.
3004 The symtabs are sorted as they are created anyway. Tell
3005 condense_misc_bunches whether we're mainline.
3006 (psymtab_to_symtab_1): Pass filename when recursing, to make
3007 stack trace more informative.
3008 (parse_partial_symbols): Assume cur_hdr as argument.
3009 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
3010 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
3011 the TYPE_NAME of char *, since that's done in symfile.c.
3012 (free_numargs, parse_symbol, add_symbol, add_block,
3013 shrink_linetable): Declare these fns void.
3014 (upgrade_type): Convert tree of if's to switch. Clean up
3015 bogus "off == 0" handling with a complaint. Avoid setting
3016 field bitpos and bitsize of array with lower and upper bounds.
3017 Check specified bitsize of elements against their actual type's
3018 bitsize, and complain if different. Complain about unknown
3020 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
3021 (psymtab_to_symtab_1): Print names of subsidiary files that
3022 are being read in. FIXME, we read far too many files. This code
3023 is not the problem, the problem is in parse_fdr where the psymtabs
3025 (cross_ref): Result should indicate that we used one aux entry
3026 normally, or two if we encountered a "next" entry. This used
3027 to leave the caller pointing at the wrong aux entry.
3028 (add_symbol): If overflowed cur_block, reallocate it larger,
3029 chase all pointers to it, and complain(), rather than clobber memory.
3030 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
3031 (new_field): Only allocate one field initially, not two.
3032 Pull ++ out of macro argument. Simplify.
3033 (_initialize_mipsread): Avoid initialization of importd
3034 global_psymbols and static_psymbols.
3036 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
3037 to properly set pst->symtab; avoid searching for it.
3038 (symfile_fns): Improve comments, add a FIXME.
3039 * dbxread.c: Update comments to reflect symfile protocol.
3040 (read_ofile_symtab, end_symtab): Return the symtab.
3041 (psymtab_to_symtab_1): Set pst->symtab.
3043 * coffread.c (coff_symfile_read): tell condense_misc_bunches
3044 whether we're mainline.
3046 * symfile.h (sym_fns): Remove unused sym_discard member.
3047 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
3049 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
3050 the environment variable is not.
3051 * infcmd.c (finish_command): Use filtered printfs.
3052 * cplus-dem.c: Add struct tags to a few unnamed structs.
3053 * valops.c (value_coerce_array): Improve comments.
3054 * valprint.c (type_print_varspec_suffix): Print array size only
3055 if greater than zero.
3056 * m88k-tdep.c: Shift some lines left by one space, that had
3057 apparently been trashed at some point.
3058 * TODO: More things to do, a few got done.
3060 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3062 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
3063 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
3065 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
3066 * expread.y, findvar.c, symmisc.c: Ditto.
3067 * printcmd.c (address_info): Update printed forms of LOC_
3068 symbols. Elim LOC_EXTERNAL.
3069 (print_frame_args): Keep track of param stack offsets before
3070 re-looking up to find the local register param is kept in.
3072 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
3073 Further integration of mipsread into gdb. Eliminate unused
3074 routines, duplicate declarations. Handle static symbols in
3075 psymtabs as well as external symbols. When reading symtabs,
3076 insert symbols into the correct block (global, static, or a local
3078 (read_mips_symtab, parse_partial_symbols): Don't pass useless
3080 (mipscoff_symfile_read): Don't call select_source_symtab.
3081 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
3082 rather than SYMBOL_VALUE.
3083 (parse_external): Comment clobbering of top_stack.
3084 (parse_partial_symbols): Update comments. Allocate and parse
3085 static symbols as well as external symbols. FIXME, enum values
3086 are not handled in this pass, but should be. Inline new_psymbol.
3087 Use SYMBOL_VALUE_ADDRESS.
3088 (psymtab_to_symtab_1): Read symbols into global static block
3089 by default (until enter some function's local block context).
3090 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
3091 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
3093 * source.c (select_source_symtab): Select a source symtab
3094 from either the symtabs or, failing that, the psymtabs.
3095 (list_command): Update error message.
3096 (forward_search_command, reverse_search_command): Use getc, not
3097 fgetc, for speed. FIXME, add comment about buffers that die if
3098 overrun by long line.
3100 * values.c (unpack_field_as_long, modify_field): Avoid shifting
3101 by an entire word, which is not portable, if we have a 32-bit
3102 field. (Code in dbxread.c already turns such bitfields, if
3103 aligned, into ordinary ints, but fixing this will help for other
3104 symbol formats and for future changes.)
3105 * core.c (core_open): Handle ANSI const brain death.
3106 * utils.c (vprintf): Fix varargs typo.
3108 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3110 * findvar.c (find_var_value): Handle &function better.
3111 * TODO: Document work needed on &fn and &array.
3112 * printcmd.c (print_address_symbolic): New arg is the prefix
3113 to print if a name is printed.
3114 (print_address_demangle): Honor "set print address" now.
3115 Use new arg above to improve spacing of output.
3116 * valprint.c (val_print): When printing function pointers,
3117 print symbolic form too.
3118 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
3120 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3122 * core.c (memory_error): Reword error msg to mislead less.
3124 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
3126 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
3127 parse_partial_symbols): Use newer BFD internals (external_filehdr
3128 and external_aouthdr), byte-swap the fields that we care about
3129 before using them, and make the file header data local to
3130 read_the_mips_symtab rather than global.
3132 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
3134 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
3135 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
3137 * main.c (command_line_input): Flush stdout and stderr
3138 before every call to readline. This reportedly fixes a bug
3139 that comes up in Sys V running emacs-gdb and/or xxgdb,
3140 when stdin/out are pipes or sockets.
3142 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
3144 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
3145 Avoid declaring Makefile dependencies, because GNU Make stupidly
3146 tries to update it if we do.
3148 * coffread.c: Revise for minor changes to bfd internal coff
3151 * configure: If -template= is given a relative path, make it
3152 absolute before recurring in subdirectories.
3154 * configure, configure.in, Makefile.in: Install "configure" script
3155 as replacement for config.gdb.
3156 * config.gdb, Makefile.dist, Makefile.sdir: Remove
3157 * README: Update for configure, mostly. FIXME.
3159 * Add dec3100 as equivalent to littlemips. Indicate in all host &
3160 target config files that they are for the host. When the lines
3161 get copied into the Makefile, this makes it more obvious what's
3164 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3166 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
3167 tabs, which end up in the disassembler output inadvertently.
3169 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
3171 Make it compile cleanly in an ANSI GCC2 environment.
3173 * blockframe.c: <stdio.h>
3174 * cplus-dem.c: free takes a void *, ifdef __STDC__
3175 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
3177 * defs.h (alloca): Avoid doing anything if alloca already def'd.
3178 * stddef.h, stdlib.h: Remove these files.
3179 * symtab.c: Avoid declaring qsort, close.
3180 * symfile.c: Avoid declaring close.
3181 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
3182 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
3184 Assorted other changes.
3185 * dbxread.c: include "libaout.h", not "liba.out.h".
3186 * printcmd.c (print_frame_args): Set recurse properly for
3187 indentation of struct and array parameters.
3188 * valops.c (value_cast): Allow cast to void.
3189 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
3190 single_step() in a target-independent fashion.
3191 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
3192 set up to be ready to continue. This makes us target independent.
3193 * infptrace.c (child_resume): Remove call to single_step; now
3194 can single step a SPARC target of any kind.
3196 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
3198 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
3199 docn into separate sections---basically chapters, plus two loose
3200 pieces that can be configured to go in different places. This
3201 allows GNU m4 to preprocess the manual without coredumping.
3203 * Makefile.dist: tell TeX where to find texinfo.
3205 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
3207 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
3208 the new target "rdl-apps.texinfo" which captures the Makefile
3209 variable that records where to find the Readline libraries.
3211 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
3213 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
3214 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
3215 * defs.h (const, volatile): Only define if not already defined.
3216 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
3218 * README: Update for release 3.95.
3219 * config.gdb: Don't create readline dir in subdir builds.
3220 * main.c: Include with "..." form for non-system include files,
3221 so "gcc -MM" for "make depend" works.
3222 Include readline files with "...h" rather than <readline/...h>.
3223 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
3225 * coffread.c: Undo minor damage done by Rich Pixley. Use
3226 different internal and external representations of COFF
3227 data structures. Use new BFD routines for swapping them in and
3229 * symfile.c (free_named_symtabs): Avoid freeing file names that
3230 are null or empty. Old i960 tools seem to produce files that
3231 claim to have empty names, causing each successive file read
3232 to blow away the previous one.
3233 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
3234 Move deferred_stores to top of file, but don't separate its
3235 #define's from its variable. Add commentary.
3236 * Makefile.dist: Fix Rich damage; undo "configure" changes in
3237 favor of keeping the (working) config.gdb. Move readline
3240 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
3242 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
3244 * infptrace.c (fetch_registers): no result, since now void.
3245 * tconfig/news: target depends on m68k-tdep too.
3247 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
3249 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
3252 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
3253 applied various small fixes due to or inspired by RMS comments
3255 * doc/gdb.texinfo: finished using all RMS comments, save those for
3256 appendices on readline and cmd history (which are in other source
3259 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
3261 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
3262 chapter 9; (2) documented 'break' command's menu mode for
3263 overloaded names, in response to hgs problem report C++ p-31
3265 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
3267 * doc/gdb.texinfo: (1) better introductory example; (2) more
3268 consistent use of @code, @samp, @file, @kbd throughout; small
3269 cleanups to first three nodes; (3) new "Contributors" node;
3270 (4) Appendix, Renamed Commands; (5) divert specialized startup
3271 instructions to "Targets" chapter for generic manuals, while
3272 leaving them up front for manuals specific to specialized
3273 environments; (6) apply fixes from RMS comments through chapter 4.
3275 * pretex.m4: modify explanatory text slightly (and redefine
3276 "regexp") to keep GNU m4 from complaining. (It still crashes
3277 later, but one step at a time...)
3279 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
3281 * readline/readline.c (update_line): Avoid dereferencing a pointer
3282 before comparing it to its bounds. Saber caught this.
3283 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
3284 and only set PC if tgetstr returned non-null. Saber caught this.
3286 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
3288 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
3289 stuff for config manual) here where it counts; updated
3290 to use new subdir structure (gdb/doc/).
3292 * Makefile: generated from above via
3296 * gdbint.texinfo: added instructions on generating gdb.info* files
3297 locally for release. These are ordinary info
3298 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
3299 Makefile)---but due to use of texinfo 2, can't count on makeinfo
3300 to generate these, so we distribute them already formatted.
3302 * gdb.texinfo: included full Info node and menu crud (as generated
3303 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
3305 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
3306 put in comments-for-future gdb.info target (one day makeinfo will
3309 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
3311 * gdb.texinfo: Updated to include new or old undocumented
3312 commands, at least the following (perhaps some others I forgot to
3313 record): info f, info float, info path, info program, info s, info
3314 set, info source, info terminal, info types, info user, set/show
3316 Also covered all recent GDB command renames for v4.
3318 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3320 * mipsread.c: Rather than keeping count of how many symtabs
3321 and psymtabs we have, for sorting purposes, count them when
3322 we need to sort. This fixes bug in rereading of symbol tables.
3324 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
3326 * infcmd.c: renamed "info path" to "show paths"
3327 * gdbrc.tex: documented above.
3329 Wed May 8 04:51:11 1991 John Gilmore (gnu at cygint.cygnus.com)
3331 * remote.c: Fix comments.
3332 * utils.c (error): Force out any pending wrap output.
3334 Sat May 4 11:11:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3336 * Makefile.dist: Roll VERSION to 3.95.
3337 Fix up "saber_gdb" to work again.
3338 * saber.suppress: Update.
3340 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
3341 symtab.h, target.c, target.h: Lint.
3342 * core.c: setup and select frame after reading shared libs,
3343 else reading shared libs will clobber them. Lint.
3344 * utils.c (error): Force out any buffered wrap text.
3346 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
3348 * remote.c: Remove decls of memory_insert_breakpoint
3349 and memory_remove_breakpoint, no longer used. (Suggestion of
3352 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
3353 to make it easier to interface to "configure"'d libraries.
3355 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
3357 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
3358 aliases for set/show print.
3360 Thu May 2 11:22:02 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
3362 * coffread.c (coff_sym_fns) [TDESC]: Make the type be m88kbcs.
3364 * m88k-tdep.c (IEEE_isNAN): New function.
3366 * infrun.c, m88k-tdep.c, m88k-xdep.c: Change
3367 initialize_{tdesc,dcontext} to init_{tdesc,dcontext}.
3369 * infrun.c [TDESC]: Add a bunch of crud.
3371 * xm-88k.h [__GNUC__]: Don't define memset.
3373 * m88k-xdep.c: #if 0 out push_breakpoint.
3375 * tm-88k.h: Define GET_SAVED_REGISTER.
3377 * tm-88k.h: Define DGUX.
3379 * m88k-opcode.h (UEXT, SEXT, MAKE): Put parentheses around arguments.
3381 * m88k-pinsn.c (sprint_address): Declare at top of file.
3383 * m88k-xdep.c: #if 0 out core_file_command.
3385 * values.c ({unpack_,value_as_}pointer): Just call
3386 {unpack_,value_as_}long (for now anyway).

3857 (_initialize_values): Rename "info values" to "show values".
3859 Sun Apr 14 23:08:34 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
3861 * inftarg.c (child_open), remote-vx{,.68}.c (vx_proc_open):
3862 New function to give correct error message.
3864 Thu Apr 11 17:19:41 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
3866 * target.h: Add to_doc and target_preopen.
3867 target.c: Add target_preopen and target_command.
3869 (add_target): Call add_cmd and mess with targetlist->doc.
3870 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
3871 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.
3872 Call target_preopen from open routine.
3874 * main.c: Rename editing_info to show_commands.
3875 (_initialize_main): Rename "info editing" to "show commands".
3877 * source.c: Rename directories_info to show_directories.
3878 (_initialize_values): Rename "info directories" to "show directories".
3880 * values.c: Rename convenience_info to show_convenience.
3881 (_initialize_values): Rename "info convenience" to "show convenience".
3883 * copying.awk (_initialize_copying): Rename "info copying" to
3884 "show copying" and "info warranty" to "show warranty".
3885 Rename {copying,warranty}_info to show_{copying,warranty}.
3887 * symfile.c: Rename add_syms_command to add_symbol_file_command.
3888 (_initialize_symfile, add_syms_addr_command):
3889 Rename add-syms to add-symbol-file.
3891 Thu Apr 18 18:08:30 1991 John Gilmore (gnu at cygint.cygnus.com)
3893 * symfile.h (free_named_symtabs): Rename from free_named_symtab.
3894 * symfile.c (clear_symtab_users_once, cashier_psymtab,
3895 free_named_symtabs): Move these routines from symmisc.c.
3896 * symmisc.c (same): same.
3897 (free_symtab): Make non-static.
3898 * symtab.h (free_symtab): Declare as exported void fn now.
3899 * dbxread.c (end_symtab, end_psymtab): Change comments.
3900 (initialize_dbxread): Call dbx_new_init() in case the first
3901 command is add-symbols.
3902 * target.c (dummy_target): Permit add_syms_addr_command.
3904 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3906 Permit symbols to be superseded when new symbol files have
3907 been read in, particularly for VxWorks.
3909 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
3910 to the main file, as well as to include files. Also, put global
3911 functions into the global psymtab, to make "i fun" work.
3912 (end_psymtab): Free named symtabs and psymtabs for a file, once a
3913 new psymtab for it has been read.
3914 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
3915 a file, once a new symtab has been read for it.
3916 * mipsread.c: FIXME. We need to do the same for MIPS, but it
3917 looks harder to determine the top-level block before it's been
3918 queued to the psymtab list.
3920 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
3921 If we have wiped out any old symbol tables, clean up at end of
3923 (symbol_file_command): Don't reference symfile_fns if it's zero.
3925 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
3926 defines for the blocks of a blockvector that contain global and
3927 file-static symbols and the first of the smaller scope contours.
3928 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
3929 decode_line_1, make_symbol_completion_list): Use the above.
3930 * coffread.c (end_symtab, patch_opaque_types): Ditto.
3931 * dbxread.c (end_symtab): Ditto.
3932 * expread.y (block): Ditto.
3933 * mipsread.c (throughout): Ditto.
3934 * symmisc.c (free_named_symtabs): Ditto.
3936 * symtab.c (list_symbols): Process the first symbol of the
3937 static psymbols list.
3938 (types_info): Restore this function from its untimely #if 0.
3939 It's not perfect, but it is better than nothing.
3940 (_initialize_symtab): Restore "info types".
3942 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3944 * m68k-stub.c: Remote stub for 680x0's, created from
3945 rem-m68k.shar (which is removed).
3946 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
3947 Remove RCS log stuff now that we use CVS and it blows our diffs.
3949 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
3951 * symmisc.c (free_named_symtab): Make it work, in its current
3952 kludgy fashion. Change result to indicate if we blew away bkpts.
3953 * dbxread.c (end_symtab): Accumulate result from
3954 free_named_symtab and print warning if we blew user's state.
3955 * symfile.h: free_named_symtab now returns an int.
3957 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
3959 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
3960 is the first symbol read, even if not mainline.
3961 (dbx_psymtab_to_symtab): symfile might be zero, cope.
3962 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
3963 (set_section_command): New command ("section xxx yyy" -- should
3964 be renamed to "set section xxx yyy" FIXME) which sets the
3965 base address of a section of the exec file, overriding the
3966 virtual address that BFD reports.
3968 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
3970 * exec.c: Add add_syms_addr_command to exec_ops, so you can
3971 load symbols at any address while examining an exec file.
3973 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3975 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
3976 for printing the float info is host-dependent, not
3977 target-dependent. FIXME.
3978 * i386-pinsn.c: Move #includes to top, remove useless ones.
3979 * i386-tdep.c: Don't bother including <.../reg.h> since we
3980 don't use it (and it doesn't exist on host systems).
3982 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
3983 Convert negative numbers properly.
3984 (ieee_test): Make numbers really random; fix format arg.
3986 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
3987 * core.c (core_detach): Unpush core_ops, which might not be on
3988 top. We used to just pop the top, which broke things. Don't
3989 need dont_repeat() any more.
3990 (core_file_command): Psst! Don't repeat it.
3991 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
3992 * expprint.c (print_subexp): Avoid switch fallthru on
3993 BINOP_ASSIGN_MODIFY, so we can print += and such.
3994 * frame.h: Fix typo.
3995 * inflow.c (kill_command): After killing inferior, print our
3996 current frame in the core file, if we have one.
3997 (generic_mourn_inferior): When inferior dies, either select
3998 the current frame (in the new target, e.g. core file), or
3999 set both the current and selected frames to NULL.
4001 Changes from Peter Schauer.
4003 * infptrace.c: Avoid <sys/ptrace.h> on USG.
4005 * Make all file names fit in 14 characters (sigh and damn!):
4006 mv hp300hpux-xdep.c hp300ux-xdep.c
4007 mv symmetry-xdep.c symm-xdep.c
4008 mv symmetry-tdep.c symm-tdep.c
4009 mv convex-opcode.h convx-opcode.h
4010 mv tm-vxworks960.h tm-vx960.h
4011 mv tm-vxworks68.h tm-vx68.h
4012 mv Makefile.srcdir Makefile.sdir
4013 mv gdb-int.texinfo gdbint.texinfo
4014 mv remote-sa.m68k.shar rem-m68k.shar
4015 mv remote-multi.shar rem-multi.shar
4016 * Makefile.dist, README, config.gdb, convex-pinsn.c,
4017 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
4018 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
4021 * command.c (user_info_1, user_info): New command for listing
4022 the user-defined commands.
4024 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
4026 * dbxread.c (really_free_pendings): Clear file_symbols
4027 and global_symbols after freeing them; otherwise, running
4028 this function twice (if it appears twice on the cleanup
4029 chain), we try to free things twice.
4031 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
4032 based on text_addr (the address of text in core), not on addr (the
4033 offset between text in the .o file and in core). This change
4034 is from Peter Schauer.
4036 * main.c: Define ALL_CLEANUPS as a cast of zero.
4037 (return_to_top_level): Use it.
4038 (main): Do all cleanups after each command run as part
4039 of the gdb startup sequence. Also do all cleanups before
4040 entering the command loop, and every time we exit the command
4041 loop and reenter. Before, the cleanups from the startup sequence
4042 were being left undone until the first error!
4043 (command_loop): Rename do_nothing cleanup to command_loop_marker
4044 so we can see it easily when examining the cleanup chain.
4045 (init_signals): Add another do_nothing for signal handling.
4046 (quit_command): Only try to kill target if it has execution.
4047 Problems in the target stack got us into a state where
4048 inferior_pid was nonzero but none of the targets had execution.
4049 In this state you couldn't exit gdb.
4051 * dbxread.c: Two changes from Peter Schauer.
4052 (echo_command): Fflush output after an echo command.
4053 (show_history): Pass all args to cmd_show_list.
4055 * utils.c (init_malloc): Call mtrace to turn on tracing
4056 if the environment variable MALLOC_TRACE is set to a file name.
4057 * mtrace.c: Add source file which provides a log of every malloc,
4058 free, and realloc to a trace file.
4059 * mtrace.awk: Add source file which analyzes the trace file.
4060 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
4061 (VERSION): Roll to 3.94.3.
4063 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
4064 (check_duplicates): Don't bother with watchpoints.
4065 (set_raw_breakpoint): Comment about danger of this routine.
4066 (watch_command): Parse and eval all args before calling
4069 * solib.c (find_solib): Avoid error in referencing memory to
4070 see if any more shared libraries have been added. This is
4071 particularly useful if the target has terminated. Bug reported
4074 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
4075 in bringing up 3.94.2 on the Sun-3.
4077 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
4078 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
4079 expression (in scope) before reenabling watchpoint.
4080 * signame.c (init_sigs): Add missing declaration of i, fix
4081 sys_siglist declaration.
4082 * source.c (list_command): Fixed range computation to use
4084 * stack.c (backtrace_command): Do not allow command if target has
4085 no stack, print informative error message.
4086 * target.c (target_command): Do not write into command line
4087 because this fails if the target command is used in a user defined
4088 command. [This change was enhanced by gnu to support any-
4089 unique-prefix matching on target names.]
4090 * valops.c (value_struct_elt): Avoid infinite loop on an
4091 erroneous attempt to print the member of function (try p main.p).
4093 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
4095 * expread.y (name_no_typename): Avoid reduce/reduce errors
4096 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
4097 Since the GDB parser really doesn't use name_no_typename in a
4098 name-only context, the parser can't tell the diff between
4099 names and numbers here. Avoid allowing a name_no_typename
4100 to be a NAME_OR_*INT to resolve the conflict.
4102 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
4104 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
4106 * valprint.c (val_print_fields): bitfield printing didn't handle
4107 byte order. Indirect through a few more fns to cope.
4109 * values.c (modify_field): also cope with byte order.
4111 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
4113 Cleanup for release 3.94.2:
4115 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
4116 include files. Roll version to 3.94.2.
4118 * coffread.c (init_stringtab): Read length into unsigned char
4119 array before swapping; don't assume 32-bit longs.
4121 * target.c (target_info): Don't bother with get_sym_file, just use
4122 the symfile global variable.
4123 * symtab.h, symfile.c (get_sym_file): Delete it.
4125 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
4126 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
4127 (read_type): Replace one more error() with complain().
4129 * mipsread.c (parse_partial_symbols): Replace printf with complain.
4131 * i960-tdep.c: Fix copyright attribution.
4133 * config.gdb: Quote all backquotes in doublequotes. You can
4134 quote me on that. BSD 4.4 shell found this one.
4136 * infptrace.c (throughout): The third argument to ptrace is an
4139 * infrun.c (wait_for_inferior): When program has terminated, we
4140 have to call target_terminal_ours before we pop that target off
4141 the stack (e.g. before a call to target_kill or
4142 target_mourn_inferior). This fixes problem where a program
4143 terminates, then GDB stops for (tty output) and you have to type
4144 "fg" to the shell to resume it. FIXME: This code for what to
4145 do after termination really should be in normal_stop instead.
4147 * gdbcore.h (read_memory_check): Change declaration; it changed
4150 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
4151 4.4 prereleases, this avoids a bug in their sgtty compatability
4153 * remote.c: Use terminal.h rather than hand-rolling the same.
4155 * signame.c, signame.h (psignal): Arg is unsigned, not int.
4156 * utils.c (strsave, strstr): Fix arg types.
4157 * valprint.c (val_print): lint
4159 MIPS symbol table support from Per Bothner:
4161 * symfile.c (symtab_fns): Remove initializer table that needs to
4162 be hacked for each new symbol file format supported.
4163 (add_symtab_fns): New function, chains symbol table
4164 handlers into the global list.
4165 (symfile_init): Search this list.
4166 * symfile.h: Add next pointer, declare add_symtab_fns.
4167 * coffread.c (_initialize_coffread): Call add_symtab_fns.
4168 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
4170 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
4171 symbol *). Thus, we no longer need the hack to trash
4172 pst->filename. Good, since that hack confused code in symfile.c!
4174 (reorder_symtabs, destroy_all_symtabs): Removed static
4175 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
4176 Instead, the latter now uses a temporary array (stack-allocated
4177 from an obstack, and then freed).
4179 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
4180 haven't been set in the outermost stBlock of a procedure. This was
4181 a problem with f77 binaries on Ultrix 4.?.
4183 (new_symtab, new_symbol, new_type): Continue changing code to use
4184 obstacks more and otherwise conform to dbxread internal style.
4185 Made the free_code of symtabs be free_linetable (as in dbxread)
4186 instead of free_contents. This implies memory leaks when reading
4187 a new symbol table, until the conversion is finished. Did change
4188 (struct symbol) and (struct type) to be allocated on the
4189 symbol_obstack. Blocks and blockvectors are among the things
4192 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
4193 tested much, but it solved one problem (reported by Meissner), and
4194 cleans up some other things. The problem happened when an
4195 included file contains actual code (functions) and not just
4196 definitions. The mips coff is a little inconvenient there, since
4197 it may cause a procedure to be mapped to the wrong psymtab.
4199 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
4200 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
4201 this will need work for the new core paradigm.
4203 Opcode patches from the net:
4205 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
4206 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
4207 missing altogether - they are added here. From Bruce Bauman.
4208 * mips-opcode.h: The low mask for C0 instructions was too small.
4209 From Garrett Lau. I modified the fix to check the entire 32-bit
4212 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
4215 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
4217 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
4219 * dbxread.c (read_type): Pointer subtraction (value_sub in
4220 valarith.c) sometimes failed because the types of the
4221 pointers being subtracted were not identical.
4222 These differed because dbxread.c was allocating pointer types
4223 using dbx_alloc_type+smash_to_pointer_type instead of
4224 lookup_pointer_type. I failed to find a justification for the
4225 former, so I changed it to use the latter. Similarly, I
4226 replaced smash_to_function_type by lookup_function_type,
4227 and smash_to_reference_type by lookup_reference_type.
4229 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
4230 _initialize_mipsread): corresponding changes.
4232 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
4234 * source.c (mod_path): Do tilde_expand on each component of the path,
4235 rather than on the (list of) paths as a whole.
4236 (print_source_lines): Set first_line_listed in addition to
4237 current_source_symtab and current_source_line. If the source was
4238 not findable, after a "dir" command to fix the problem,
4239 a "list" would get the wrong lines.
4241 While I was there... (gnu):
4243 * dbxread.c (read_type): Change error to complaint.
4245 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
4247 First attempt at detailed understanding of symbol table memory alloc.
4249 * dbxread.c (dbx_symfile_read): Free our string table if we
4250 aren't the mainline. Free the "info" struct since we're done with
4252 (init_psymbol_list): Free any previously allocated psymbol lists.
4253 (): FIXME: Should realloc-down the psymbol lists when done reading
4254 the main symbol file?
4256 * symmisc.c (free_symtab): Free fullname field too.
4258 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
4259 (REGISTER_ADDR): Make result type unsigned int.
4261 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
4262 define REGEX must also define REGEX1 (its dependency).
4264 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
4266 * tconfig/i960: No longer works, points you at vxworks960 or
4269 * xgdb.c, XGDB-README: Remove file. Users can get the much
4271 * Makefile.dist: Remove all trace of xgdb.
4273 * breakpoint.c (breakpoint_1): Pass demangle arg to
4274 print_address_symbolic.
4275 (clear_breakpoints): Remove unused function.
4276 (breakpoint_re_set_one): Guts of breakpoint_re_set.
4277 (breakpoint_re_set): Use catch_errors to do them all anyway.
4279 * gdb-int.texinfo (Host versus Target): Add section on what is
4280 a "host" feature versus what is a "target" feature.
4282 * infcmd.c (path_command, path_info): Handle the PATH variable
4283 (object search path) as conveniently as the source search path.
4284 * environ.c (set_in_environ): Set some vars in GDB's environment,
4285 in addition to the child's. PATH, G960BASE, G960BIN for starters.
4286 * source.c (mod_path): New function, from guts of
4287 directory_command, modifies a path. Used by path_command.
4288 (directory_command): Call it.
4289 * defs.h (strsave): Declare.
4291 * utils.c (sevenbit_strings): Add new printing option.
4292 (printchar): Use it.
4293 (strsave): Provide this handy helper routine.
4294 (set_width_command): Rename set_screen_width_command.
4295 (_initialize_utils): "set screen-width" => "set width";
4296 "set screen-height" => "set height"; add sevenbit-strings.
4298 * infcmd.c (do_registers_info): Print floating point registers
4299 in raw hex as well as float format, regardless of whether it is
4300 a "virtual" convertible register.
4301 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
4302 regs as a double, just in case it's being used that way.
4303 * values.c (unpack_long): Comment on array/function coercion.
4304 (unpack_double): Argument is in target byte order now. For
4305 integer arguments, just call unpack_long and float the result.
4306 * m68k-tdep.c: include defs.h for "const" handling.
4307 * remote-nindy.c: Use ieee-float stuff.
4308 (nindy_fetch_registers): Unpack double regs to host double, then
4310 (nindy_store_registers): Pack extendeds to host double, flip
4311 around by misusing unpack_double, send as target double.
4313 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
4314 zero, as when stopped at the first instruction of a process.
4316 * blockframe.c: Fix filename in comment (param.h => tm.h).
4317 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
4318 * tm-68k.h: Fix typos.
4320 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
4322 Changes from a bringup on the DEC Vax under Ultrix 4.0.
4324 * coredep.c (fetch_core_registers): Pass end-address of register
4325 section to register_addr as expected. Don't call supply_register
4326 if we'd just pass it garbage.
4328 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
4330 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.

4335 * stack.c (print_frame_info): Identify source file & line
4336 even if we can't print it.
4338 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
4340 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
4342 Clean up IEEE floating point support.
4344 * ieee-float.h: New file.

4354 * m68k-tdep.c: Define ext_format_68881.
4355 * sparc-tdep.c: Define ext_format_sparc, though unused.
4356 * Makefile.dist (HFILES): Add ieee-float.h.
4357 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
4360 Obsolete the "coffstrip" program in favor of using BFD's strip.
4362 * nindy-share/coffstrip.c: Remove file.
4363 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
4364 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
4365 * tconfig/nindy960: Remove reference to coffstrip.o.
4367 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
4369 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
4371 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
4372 * dbxread.c: Remove static symfile_bfd.
4373 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
4375 * inftarg.c (child_detach): Pop the child_ops vector if the
4376 detach is successful.
4377 * remote-nindy.c (nindy_create_inferior): Don't push a new
4378 nindy_ops since nindy uses the same one for execution and memory
4380 * core.c (core_ops): Use child_attach and child_create_inferior
4381 rather than default attach and create_inferior functions.
4383 Handle floating point registers in core files.
4385 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
4386 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
4387 This version untested since BFD doesn't yet support sun3 core
4389 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
4390 conventions. Fix comments and style. This version has not
4391 been compiled yet, since we have no HP inhouse.
4392 * core.c (get_core_registers): Look for two sections, ".reg"
4393 and ".reg2", and pass both to fetch_core_registers sequentially.
4395 Revise directory path yet again.
4397 * source.c (forget_cached_source_info): Not static any more.
4398 (init_source_path): New default source path is "$cdir:$cwd".
4399 (dir_command): Handle variable arguments ($cdir, $cwd).
4400 (source_info): Print "Compilation directory" rather than
4401 "Originally compiled in" to remind people of $cdir.
4402 (openp): If the path contains $cwd, use current directory.
4403 (open_source_file): If compilation directory is known, replace
4404 first $cdir in path with the compilation directory.
4405 (print_source_lines): Even if we can't print the lines, set the
4406 current symtab and line for future commands like "info source" or
4407 "breakpoint". Also, error message now contains the file name,
4408 line number, and file access error message.
4409 (_initialize_source): Fix help text to describe changes.
4410 * main.c (cd_command): Forget cached source info when we chdir.
4411 * utils.c (strstr): Add simple implementation.
4413 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
4415 * coffread.c (read_one_sym, init_linetable, init_stringtab):
4416 Byte-swap COFF symbol tables if necessary when reading them in.
4417 Use complain() to replace error message in one spot. Needs
4418 corresponding change in bfd/coff-code.h to make some symbol
4419 swapping routines non-static.
4421 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
4423 Merge changes from Eirik Fuller, for UTek.

4430 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
4431 declarations of errno.
4433 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
4435 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
4436 <rpc/rpc.h> and <rpc/types.h>.
4438 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
4440 * i960-tdep.c (examine_prologue): Add new argument limit,
4441 which stops the scan at the end of the prologue, or at the PC.
4442 This fixes a problem where it walks down into the code for the
4443 user's statements if that code looks like function prologues.
4444 Mark Fox and I have been bouncing this code back and forth, making
4445 small changes to it. Callers changed to match.
4447 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
4449 Cleanup for gdb-3.94 release final:
4451 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
4452 the .c files from vx-share and nindy-share, from the various
4453 macros, since they are not found via ALLDEPFILES.
4454 (SFILES): Add tm-i960.h.
4455 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
4456 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
4458 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
4459 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.

4463 * am29k-tdep.c: Add contribution line.
4464 (examine_prologue): Cache information about function prologues in
4465 the misc-function-vector to avoid lots of references over the
4466 serial line while examining instructions.
4468 * core.c (core_close): New function made from cleanup_core.
4470 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
4471 remote-vx.c, remote.c, target.c, target.h,
4472 Update target_ops vector to add attach, close, and load entries.
4473 Use add_syms_addr_command, not add_file_addr_command, for
4474 add_file. Break out close routine from existing code.
4476 * dbxread.c (really_free_pendings): Don't free pending_blocks;
4477 they are in an obstack.
4478 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
4480 (define_symbol): Add symbol type parameter; change callers;
4481 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
4482 it to influence the symbol class on the i960.
4483 (define_symbol): Swap LOC_CONST's into target byte order.
4485 * exec.c (exec_close): New function.
4486 (exec_file_command): Call it.
4488 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
4489 Fix byte order of frame pointer.
4490 (read_var_value): Result of 0 if var's value can't be found,
4491 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
4492 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
4493 (locate_var_value): Use read_var_value and use its lazy address
4494 as the location of the var's value. Lint.
4496 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
4499 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
4500 obsolete Intel versions in favor of vxgdb versions.
4501 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
4502 code dealing with byte order of values, which Intel did in host byte
4503 order rather than gdb-4's target byte order.
4504 (i960_frame_chain_valid): Move to nindy-tdep.c.
4505 (examine_prologue, skip_prologue, frame_find_saved_regs,
4506 frame_args_address, leafproc_return, saved_pc_after_call,
4507 pop_frame): Add vxgdb versions from Mark Fox.
4508 (examine_prologue, frame_struct_result_address): Add code
4509 to deal with the saved value of G13 (struct return address
4511 (frame_args_address): Modify Mark's version to prefer the
4512 saved value over the current value in the topmost frame.
4513 Cache result in the frame info to avoid performance hair in
4515 (print_fault): Add gdb960 code for printing faults.
4516 (_initialize_i960): Actually call check_host.
4518 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
4519 add stub routines. FIXME, these currently just return zero!
4521 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
4522 (attach_command): Call target_attach, not target_open, now.
4524 * infrun.c (normal_stop): Make global, not static, for vx_attach.
4525 (child_attach): Rename from child_open.
4526 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
4527 don't confuse it with a zero step_resume_break_address.
4529 * inftarg.c (child_detach): Eliminate inferior_pid test.
4530 (child_files_info): Clean up message a bit.
4531 (child_ops): Use child_attach, not child_open, to attach.
4533 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
4534 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
4535 findvar.c to here, since it depends on the contents of the
4536 shadow_contents of breakpoints, but keep if #if 0 since it is
4539 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
4542 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
4543 (ptype_command, display_command): Eliminate have_inferior_p and
4544 have_core_file_p in favor of target_has_stack or
4545 target_has_execution.
4546 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
4547 code for actually finding the values of arguments, though we still
4548 keep track of the maximum stack offset for use in printing unnamed
4549 arguments. Handle missing FRAME_ARGS_ADDRESS.
4551 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
4552 (struct nindy_regs): Define registers passed to/from nindy.
4553 (nindy_fetch_registers, nindy_store-registers): Translate between
4554 nindy and GDB formats for the registers.
4555 (dcache_init): Statically allocate the cache, since it was being
4556 allocated by a malloc that was never freed anyway.
4557 (nindy_create_inferior): Error, not core dump, if no exec file.
4558 (nindy_before_main_loop): Use target_load, not target_add_file.
4560 * remote-vx.c (net_load): Specify large timeout for load
4561 requests. Allow user to break out with INTERRUPT.
4562 (net_break): Remove useless code, clean up. Change callers.
4563 (parse-args, skip_white_space, find_white_space): Clean up arg
4564 parsing to cope with quoted strings.
4565 (net_wait, net_quit): Never call error, just return status.
4566 (vx_read_register, vx_write_register): Cleanup status checking.
4567 #ifdef the code based on which CPU we are using (960 or 68k),
4568 FIXME, this should be completely general but it isn't yet.
4569 (vx_xfer_memory, vx_resume): Cleanup status checking.
4570 (vx_run_files_info): Improve message.
4571 (vx_load_command): Renamed from vx_add_file_command. Allow load
4573 (net_ptrace): Remove unused routine.
4574 (vx_wait): Adopt code from vxgdb960 to cope with broken
4575 connections to target machine and prompt to disconnect. Remove
4576 debug printouts. Map some EVENT_'s to SIGnals.
4577 (add_symbol_stub, vx_open): Print names of object files we found,
4578 and "ok" if we read their symbols OK. Clarify output in general.
4579 (vx_attach, vx_detach, vx_kill): Add these commands.
4580 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
4581 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
4582 "info files" output, and create_inferior, since we already have
4585 * stack.c (frame_info): Replace Frame_unknown with 0.
4586 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
4587 (return_command): Pop until the PC matches as well as the FP,
4588 so it works even if the FP is shared with another function,
4589 as in "frameless" or "leaf" procedures.
4591 * symfile.c (load_command): renamed from add_file_target_command.
4592 (add_syms_addr_command): renamed from add_file_addr_command.
4593 (add_syms_command): Stub to call target_add_syms.
4594 (_initialize_symfile): Change command names and descriptions,
4595 add-file => add-syms, and load from alias to its own command.
4597 * target.c (kill_or_be_killed, maybe_kill_then_attach,
4598 maybe_kill_then_create_inferior): Default for attempts to start
4599 a process, if one is already running, is to ask about killing
4600 it and retry if yes.
4601 (upstack_create_inferior): #if-0 it, strata obsolete it.
4602 (push_target, unpush_target, pop_target): to_close() a target
4603 before unstacking it.
4604 (target_info): Renamed from target_files_info.
4605 (_initialize_targets): Rename "i files" as "i target", accessible
4608 * target.h: Improve comments about the target_ vectored routines.
4610 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
4611 Convert commenting style to standard GNU style.
4612 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
4613 (SKIP_PROLOGUE): No longer a no-op.
4614 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
4615 (*_REGNUM): Sort register numbers.
4616 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
4617 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
4618 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
4619 are now 10 byte extendeds, not 8 byte doubles.
4620 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
4621 for nindy versus vxworks targets. FIXME, this should possibly go
4622 in the target vector.
4623 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
4624 frame_saved_regs and arg pointer with each frame.
4625 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
4626 (FRAME_ARGS_ADDRESS): Use cached result.
4627 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
4628 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
4629 (PRINT_RAMDON_SIGNAL): Call print_fault.
4630 (POP_FRAME): Now works.
4632 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
4633 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
4634 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
4635 (ADDITIONAL_OPTION_HANDLER): use target_load, not
4638 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
4639 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
4641 * valarith.c (value_subscripted_rvalue): Avoid handling
4642 floats and doubles specially; it gave alignment errors. Lint.
4644 * valops.c (value_of_variable, value_of_this): Error if unknown
4647 * valprint.c (print_floating): Bcopy rather than pointer-deref,
4648 to avoid alignment problems.
4649 (value_print): Handle unknown value address.
4650 (cplus_val_print): Two args are ignored; remove them. Change caller.
4651 (val_print): Use unpack_long rather than pointer-deref.
4654 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
4655 to avoid alignment problems.
4656 (value_being_returned): Error if return value unknown.
4657 (set_return_value): Add bogosity warning, FIXME. *
4659 * TODO: A woman's work is never done.
4661 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
4662 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
4663 Add ieee-float.o to OBS.
4664 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
4665 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
4666 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
4668 Changes to generalize the VxWorks RPC protocol slightly, to handle
4669 i960 as well as 68000.
4671 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
4672 * vx-share/reg.h: Produce i960 regs #ifdef I80960
4673 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
4674 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
4675 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
4676 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
4677 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
4678 so they will move in target byte order rather than network
4679 byte order (happens to be the same).
4681 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
4683 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
4685 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
4688 Add contribution lines to various files, showing where they
4691 * breakpoint.c (break_insn, check_break_insn_size,
4692 read_memory_nobpt): Remove to mem-break.c.
4694 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
4697 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
4698 entry has bad register number. This change is not
4699 tested in this release, FIXME.
4701 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
4704 * value.h: Force value's contents field to be aligned to hold
4705 at least a double or a long long (if supported). This avoids
4706 doing bcopy's in and out of the contents field.
4708 (step_1): Avoid coredump under obscure circumstances when we
4711 * symtab.h (misc_info): Add field to misc function vector for
4712 any kind of cached information the target code desires. AMD
4713 29000 uses this to avoid repeating examine_function_prologue's.
4715 * coffread.c: Lint. Remove static symfile, read_section_header.
4716 core.c (have_core_file_p): Lint: remove.
4717 expprint.c (print_subexp): Lint.
4718 infptrace.c, valops.c, valprint.c: lint.
4720 Roll in changes from vxgdb-5.0.1:
4722 * symtab.h: Comment byte order of each address class. Add
4723 LOC_LOCAL_ARG for frame-relative args (960).
4724 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
4725 symtab.c, symmisc.c: ditto.
4727 * infrun.c (init_wait_for_inferior): Clear stop_signal.
4729 * remote.c (remote_resume): Error if resume with a signal.
4731 * symfile.c (prim_record_misc_function): Clear misc_info.
4732 (fill_in_vptr_fieldno): Check stub type of arg.
4734 * valops.c (value_cast): Avoid looking up names of types whose
4735 name we don't know, to prevent coredump. Sun CC produces typedef
4736 rtx and the name of *rtx is zero...
4738 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4740 Roll in changes from final AMD 29000 port (Tiemann).
4742 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
4743 for ../include/a.out.encap.h. This might not work now that BFD
4744 is separately compiled. Instead, BFD support for encap will have
4745 to translate machine type 29k into the right COFF_MAGIC.
4747 * infcmd.c: Remove references to inferior_pid that aren't used
4748 in actual ptrace calls; use target_has_execution, etc.
4749 (have_inferior_p): Remove function.
4750 (program_info): Print target info rather than "process number";
4751 avoid gratuitous messages unless from_tty.
4752 (run_stack_dummy, finish_command): Set proceed_to_finish.
4753 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
4754 main.c: Lint. Lose have_inferior_p().
4755 inferior.h (have_inferior_p): Remove, lint.
4756 (proceed_to_finish): Add flag to ask that all regs be saved
4757 by normal_stop, for the few commands that need it, speeding up
4758 serial I/O. Add comments to stop_registers.
4760 * remote-eb.c: Remove newline from breakpoint message we grep
4761 for. Never time out when running the user program.
4765 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
4767 Roll in changes from vxgdb-5.0.1:
4769 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
4770 symbol in its raw form, we are processing an unlinked ".o" file.
4771 See if the target environment has assigned it an address, using
4772 target_lookup_symbol (VxWorks does), and enter it into the symtab
4775 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
4776 68k versions for a simpler version that assumes zero FP at bottom.
4777 Fixes bug of truncated stack reports.
4779 * target.h (target_lookup_symbol): Define this routine's args
4780 and result, finally.
4782 * target.c (nosymbol): Default routine for target_lookup_symbol.
4783 (target_default): Default lookup_symbol and call_function too.
4784 (files_info): Only print has_all_memory warning if a non-dummy
4787 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
4788 vx_convert_from_virtual): If target does not have floating point,
4789 zero register "values", and avoid doing cross-net conversions.
4790 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
4791 (vx_open): Rearrange code that attaches to target and reads
4792 symbols for all loaded modules, to work if some of the modules
4793 are not accessible. Add symbol_stub() and add_symbol_stub()
4794 as callbacks from catch_errors(). Allow connect attempt to be
4795 interrupted painlessly with ^C (FIXME, there are still some bugs
4796 if the interrupt happens during symbol reading.). Print
4797 final message with puts_filtered, since symbol messages are
4802 * main.c (catch_errors): Only print errstring if non-null.
4803 (command_loop): Avoid an ioctl per command to test ISATTY.
4805 * remote-vx.c (net_load): make static; avoid sophomoric msg.
4806 (vx_xfer_memory): Return correct result!
4807 (vx_files_info): Indicate whether target has float or not.
4808 (vx_lookup_symbol): Complain, not error, if target gone.
4809 (vx_open): Print "Connected" msg before disabling immediate-quit.
4810 [FIXME: lookup_symbol and vx_open changes need testing.]
4812 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
4813 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
4814 contributor lines and update copyrights to 1991.
4816 Changes from an attempted H-PUX host port:
4818 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
4819 defines PT_ATTACH and PT_DETACH but not PT_KILL.
4820 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
4821 * remote-vx.c: include <sys/time.h> for HPUX.
4822 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
4823 "core_file_command" routine to BFD regime. May not work yet.
4825 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
4827 * xgdb.c: Replace X10 version with some VJ version.
4828 (FIXME: Its copyright assignment is not on record.)
4829 * xgdb.c: Update include files to X11R4 (Xaw crud).
4830 (xgdb_display_source, create_text_widget): fix call to
4831 get_filename_and_charpos. Rewack source window stuff for X11R4
4832 (gleaned from include files, and "nm's" of binary libraries, since
4833 I had no doc available).
4834 (append_selection, append_selection_word): Disable with FIXME
4835 since R4 changed interface here.
4836 (create_buttons): Add back the old set of buttons.
4837 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
4839 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
4840 Roll VERSION to 3.94 (not yet final though).
4842 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4844 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
4845 obstack_int_grow, obstack_int_grow_fast): Eliminate
4846 cast on left of assignment, which gives MIPS cc fits and is
4849 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
4850 F_ALIAS. Use printf, not fprintf, when not passing a file
4852 (compare_opcodes): Check that identical instructions have
4853 identical opcodes, complain otherwise.
4855 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
4856 was reported by Roland McGrath.
4857 (unimp): Only match if exactly zero instruction. (Roland)
4858 (branches and traps): Generate all variations of these
4859 instructions with macros, based on a single call that defines
4860 each condition name and its binary representation.
4861 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
4863 * valprint.c (val_print_fields): Take, and use, format parameter.
4864 This means that "p/x struct" again prints the elements in the
4865 desired format. Changed callers.
4867 * stack.c (frame_info): Use filtered output, and indicate wrap
4868 points. Remove kludgy formatting designed to avoid line wrap.
4870 * utils.c (wrap_here): If the line is already full (because
4871 we had printed a long indent or long wrapped string), do an
4872 immediate newline-and-indent.
4874 * m68k-pinsn.c (print_insn_arg): Bugfix from
4875 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
4876 instruction is incorrectly disassembled as bkpt #8.
4878 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
4879 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
4880 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
4881 and then will dump core (sometimes). I traced it back to an
4882 uninitialized symfile_name in psymtab_to_symtab.
4883 (const_vol_complaint): Add quotes to message.
4884 (define_symbol): Only believe line number if gcc_compiled.
4885 Avoid allocating symbol if we will not return it.
4887 Add target strata support so that newly established targets go
4888 into their right place in the target stack (e.g. a new exec file
4889 doesn't wipe out the ability to access the running process).
4891 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
4892 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
4893 and initialize it properly in all the targets.
4895 * target.h: Document strata. Change return type of push_target.
4897 * target.c (nomemory): new function for dummy memory access.
4898 (tcomplain): Rename complain, now also used in symfile.c.
4899 (push_target): Push targets within strata. New return value shows
4900 whether new target is on top of stack or not. Always keep dummy
4902 (target_files_info): Ignore dummy target.
4904 * core.c (core_open): Warn user, and skip accessing file, if the
4905 core target is not the topmost target in the stack.
4906 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
4909 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
4910 target_ops, it doesn't belong there since we have no regs there.
4911 Change name of target from machine => memory to clarify.
4913 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
4915 * Freeze version 3.93 for release.
4917 * Makefile.dist: Handle vx-share and nindy-share subdirs
4918 properly when building gdb.tar.Z.
4920 * symtab.c: lint; add no_symtab_msg to consolidate the messages
4921 printed in various places, so I could change just one copy.
4923 * dbxread.c, coffread.c: Change references to bfd->iostream
4924 to cast to FILE *, now that BFD avoids needing types defined
4925 in other header files.
4927 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
4929 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
4930 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
4931 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
4932 (actually gcc -Wall).
4934 * dbxread.c: Remove first_global_sym, last_global_sym, since
4935 they are never referenced.
4937 * defs.h (baud_rate): Declare.
4938 main.c: Define it, and add the -b option to set it.
4940 * gdb-int.texinfo: Add text on how to define a new host or target
4941 architecture, prompted by Per Bothner's questions about MIPS
4944 * gdb.texinfo: Document "complaints". Change doc of -q since
4945 gdb no longer prints the copyright and blurb if you specify a file
4946 name to be debugged (just like Emacs). Add doc for Nindy-specific
4947 command line flags for specifying target serial port and such.
4948 Update copyright to 1991.
4950 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
4951 has taken over for us the job of ripping up executable files. The
4952 crud caused Per Bothner's port to not compile.
4954 * infrun.c (normal_stop): Avoid printing "Program exited
4955 normally" if we are in batch mode. This allows a GDB which
4956 executes a program on a target system, to behave like a Unix
4957 command (input from stdin, output to stdout, no extraneous
4960 * main.c (main): Allow additional machine-dependent command line
4961 options to be specified with the ADDITIONAL_OPTIONS,
4962 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
4963 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
4964 processing to occur just before the main loop with
4965 BEFORE_MAIN_LOOP_HOOK.
4966 (main): If a "core file" argument is specified, and it is not a
4967 core file, try it as a process ID to attach.
4968 (symbol_completion_function): Attempt to cope with
4969 "show screen-" TAB, not very successfully. This needs more work,
4971 (batch_file): New function, returns whether we are reading
4972 commands from an interactive tty on stdin, or from somewhere else.
4973 Called by normal_stop since it doesn't get from_tty passed down
4974 to it like many commands do.
4976 * remote-nindy.c: Handle command line options for nindy
4978 (nindy_before_main_loop): Prompt user for tty name if they
4979 don't specify it before getting to the interactive command loop.
4981 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
4982 and -r command line options. Also add hook before main loop
4983 to make it easy to specify a tty.
4985 * TODO: More things to do, one done.
4987 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
4989 * dbxread.c: Make complaint() calls pass pointer, not struct.
4990 Add complaints about badly formatted C++ type information
4991 (const/volatile indicator, and parse errors resulting in
4992 error_type). Fix C++ virtual member fn comment.
4993 (read_struct_type): Avoid bumping pointer if we got a parse
4994 error; this prevents our walking beyond the end of a string.
4995 Terminate loop on null char as well as semicolon.
4996 (process_one_symbol): Fix the LBRAC fix so that it uses the
4997 last previous SLINE, FUN, or SO record's PC address. C++ debug
4998 symbols did not have SLINE records in a useful order compared
4999 to the LBRAC records.
5000 (define_symbol): Handle "catch" records.
5002 * symtab.c (check_stub_type): Added new complain
5003 `stub_noname_complain' and added a consistency check to
5004 keep the debugger from crashing when finishing from an
5005 exception frame. A real fix will be needed later.
5007 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
5009 * infcmd.c (attach_command): Make global.
5011 * Makefile.dist (REMOTE_OBS): Make these compile by default,
5012 but make them easy to comment out. Perhaps later they should
5013 be enabled by what CPU you configure for? FIXME.
5014 (VERSION): Roll to 3.93.
5015 (pinsn.o): Remove rule for obsolete file.
5016 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
5018 Run down a problem that manifested by printing the wrong function
5019 name in stack traces of read_ofile_symtab. Turned out that the
5020 problem was the SunOS 4.1.1 (and previous) C compiler outputs
5021 the LBRAC symbol with an address in the *data* segment, which
5022 blew our binary search through the blocks.
5024 * dbxread.c: Use the complain() facility consistently to bitch
5025 about problems in the symbol file we are reading.
5026 (finish_block): Add code to check the nesting of the blocks;
5027 complain and Procrust them to fit if wrong.
5028 (make_blockvector): Check the order of the blocks, complain
5029 [but don't cope] if wrong.
5030 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
5031 symbols to be sure their PC value is greater than the last SLINE
5032 (line number) symbol we've seen, complaining and adopting the
5033 SLINE PC value if wrong.
5035 * symfile.h (struct complaint, complaint_root, complain,
5036 clear_complaints): Add.
5037 * symfile.c (complain, complaint_root, clear_complaints): Add
5038 facility to deal with non-fatal complaints and to regularize their
5040 (symbol_file_add): Clear complaint counters to allow new complaints.
5041 (initialize_symfile): Add 'set complaints' and 'show complaints'.
5043 * dbxread.c (dbx_symfile_read): Remember the address and size
5044 of the string table for the main symbol file, so we won't read it
5046 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
5047 to avoid reading the string table yet again. Lint.
5048 (throughout): Improve filtered output, including word wrap.
5049 (read_range_type): Improve Bothner's fix to handle other types too.
5051 * utils.c: Improve line wrap implementation. Handle unlimited
5052 width by making chars_per_line unsigned.
5053 (puts_filtered): New, easy, function.
5055 * defs.h (puts_filtered): add.
5057 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
5058 call the identical sort_symtab_syms() in symfile.c instead.
5060 * expread.y: Suggest the `file' command rather than `symbol-file'.
5062 * command.h (enum var_types): Add zinteger for seroable
5064 * command.c (do_setshow_command): Handle var_zinteger. Restructure
5065 nested if's into a switch.
5067 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
5068 we did not stop because of a breakpoint (it must have been for
5069 some other reason, like a "stepi"), so don't print anything.
5071 * symtab.c: Include <sys/types.h> all the time. Now that BFD
5072 doesn't include <sys/types.h>, old SunOS's require it for
5075 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
5077 A test port of gdb-3.92.6 to the Sony NEWS.
5080 Don't normally link in remote- or vx stuff.
5081 Some of it doesn't compile, and it wastes space for 99% of the users.
5082 Remove reference to no-longer-used HAVE_VPRINTF.
5083 Fixed BFD_DEP typo to BFD_DIR.
5085 Fix cast in arg to bfd_h_getlong.
5086 Make char *prefix be const.
5087 Fix how certain range types are mapped into builtin unsigned int types.
5089 Remove 2 #includes. They cause errors (on Sony, at least),
5090 and aren't needed (they wern't in earlier versions).
5092 print_address_symbolic should never demangle labels
5093 (since it prints *assembler-level* labels).
5095 [This was superseded by the change to printcmd below.]
5098 Add some "volatile" return types to avoid warnings.
5099 If MISSING_VPRINTF add vprintf function and not just macro
5100 (since vprintf is used in printcmd.c).
5102 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
5103 (The latter isn't grokked by some PCC-based compilers.)
5105 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
5107 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
5108 * nindy-share/coffstrip.c
5109 Added some forward declarations (otherwise, gcc complains
5110 about implicit extern redefined as static).
5112 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
5114 Changes inspired by Per Bothner:
5115 * printcmd.c (print_address_symbolic): Take additional parameter
5116 specifying whether to demangle.
5117 (print_address): Pass in asm_demangle to control demangling.
5118 (print_address_demangle): New fn, takes explicit arg to control
5120 * utils.c: Add new vars demangle and asm_demangle, and let them
5122 (fputs_demangled): If !demangle, just print the argument.
5123 (fprint_symbol): If !demangle, just print raw symbol.
5124 * valprint.c (val_print): Call print_address_demangle rather than
5125 print_address, to cause demangling to depend on the global
5126 rather than assembler-level demangling setting.
5127 * WHATS.NEW, gdb.texinfo: Document.
5129 * main.c (show_command): Show all settings if no arg.
5130 (initialize_main): Make "info set" the same as naked "show".
5131 * command.c (cmd_show_list): Handle prefix commands in the
5132 list, and print the name of the setting as well as its English
5133 description and value.
5135 Allow gdb functions to specify where a line should wrap if it
5136 exceeds the size of a terminal line. Use it to make the output
5138 * utils.c (set_screen_width_command): New fn, mallocs a buffer
5139 of the right size when screen width changes.
5140 (set_screensize_command, screensize_info): Remove #if 0'd fns.
5141 (wrap_here): New fn, indicates a point in the output where we
5142 should wrap the line rather than just letting it overflow at a
5144 (fputs_filtered): Implement wrapping.
5145 (n_spaces): New fn, returns a pointer to N spaces.
5146 (print_spaces_filtered): Use n_spaces.
5147 * defs.h (n_spaces): Declare.
5148 * stack.c (print_frame_info): Wrap with 4-space indent after
5149 fn name and before filename and line number.
5150 * printcmd.c (print_frame_args): Wrap with 4-space indent
5151 before each argument name is printed.
5152 * valprint.c (value_print): Wrap with no indentation before
5154 (val_print_fields): Wrap with indentation relative to nesting
5155 level before each field name.
5156 (val_print): Wrap with nesting indentation before array elements.
5157 * command.c (do_setshow_command): Avoid extra newlines,
5158 wrap with 4-space indent around values printed, end with period.
5159 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
5161 * breakpoint.c (breakpoint_1): Implement addressprint for
5162 "info breakpoints" display. Change file name and line number
5163 format to " at file:nnn" rather than " (file line nnn)".
5164 * gdb.texinfo: Document.
5167 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
5169 Frozen for gdb-3.92.6 release.
5171 README, WHATS.NEW: Update for 3.92.6 release.
5173 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
5174 coffread.o from configs since it is now built by default.
5175 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
5176 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
5177 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
5178 from configs since it is now built by default.
5180 Makefile.dist: Update for release 3.92.6. Handle files that
5181 have been moved to ../include, ../getopt, or ../bfd. Add
5182 saber.suppress and tests directory. Add config.status to
5183 the release (it will say "none").
5185 coredep.c: Minor formatting fixes.
5187 These changes were made in early December but only checked in now:
5188 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
5189 nindy-share/nindy.c: lint
5190 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
5191 register values coming back from the target; we store values
5192 in target byte order everywhere.
5194 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
5196 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
5198 * valprint.c (cplus_val_print, val_print_fields): New functions,
5199 which print C++ objects. They conspire to avoid printing a
5200 virtual base class more than once, following all the twists and
5201 turns of C++ virtual base rules.
5202 (val_print): Call the above rather than do it by hand.
5204 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
5205 symbol file, not for added files like shared libs. This really
5206 needs to be generalized to a timestamp per file.
5208 * core.c (cleanup_core): Avoid coredump if no core file.
5210 * config.gdb: Accept -host or -target in place of +host or
5213 * coffread.c (find_linenos): Avoid desupported BFD interface
5214 to line numbers. We still read them manually rather than using
5215 BFD's "generic" features.
5217 * gdbrc.tex, threecol.tex: Add GDB reference card and its
5219 Makefile.dist: Add refcard to OTHERS list for creating tar files.
5221 * Makefile.dist: Eliminate use of $< in explicit targets.
5223 * readline/Makefile: Use $< rather than $*.c, which does not
5224 include the VPATH in GNU Make.
5226 * tconfig/i960-bout, tconfig/i960-coff: These are identical
5227 copies of tconfig/i960, added for global configuration
5228 compatability. All i960 versions can read both coff and b.out.
5230 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
5231 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
5234 * TODO: Think of more things to do.
5236 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
5238 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
5239 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
5240 64-bit float conversion.
5242 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
5243 equivalent to sun?os4 so global config works.
5245 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
5247 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
5249 * main.c: Only declare linesize once; declare pagesize not at
5250 all, since it is never used.
5251 (main): Clear newly allocated line before it is used.
5253 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
5255 Further stabilization for the Intel 960.
5257 * Makefile.dist: Parameterize the location of the "include"
5258 and "bfd" directories, as well as "getopt". Add symfile.c.
5259 Link in both dbxread and coffread. Fix up "make depend" to
5260 rewack the locations of include, bfd, and getopt in its output.
5262 * README: Document moving include files, improve some of
5265 * coffread.c: Move common code out to symfile.c. Change
5266 symbol_file_command style interface to use new *_symfile_init
5267 and *_symfile_read interface under BFD. Use BFD internal
5268 info to locate line table, symbols, etc.
5270 * core.c (core_fetch_registers): Rename to get_core_registers
5271 to avoid confusion with fetch_core_registers.
5272 (register_addr): Move to coredep.c, which is already machine
5273 dependent. This leaves core.c pretty clean of dependencies.
5275 * coredep.c (register_addr): Accept this routine from core.c.
5277 * dbxread.c: Move common code (with coffread.c, etc) into new
5278 symfile.c. Each psymtab now contains a pointer to the
5279 format-dependent function that knows how to read it in. Make
5281 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
5282 (process_one_symbol): Add code to complain about a "compiler bug
5283 we muzzle here", if we actually see it.
5285 * eval.c (evaluate_subexp): Insert missing "break" statements
5286 in code that determines whether a variable is an lvalue in
5287 memory, register, or whatever. I detected this via a compiler
5288 bug in which it *almost* mashed out the whole switch statement.
5290 * gdb-int.texinfo: Add minor sections on configuring gdb for
5291 release, and about the README file.
5293 * infcmd.c (registers_info): Fix formatting somewhat. Still
5294 not as pretty as before, but it handles byte swapping.
5296 * remote-nindy.c: If data cache routines are interrupted while
5297 waiting for the remote end, be sure that any uninitialized cache
5298 blocks are on the free list, not on the valid list!
5300 * symfile.h: Flesh out this header file with all the various
5301 routines and variables that have been merged in from dbxread.c
5302 coffread.c, and symtab.c to symfile.c.
5304 * symfile.c: New file, containing code common to dbxread.c,
5305 coffread.c, and some code from symtab.c. All generic code for
5306 reading symbol files should be in here now.
5307 (unrecord_misc_function): Remove unused function.
5309 * symtab.h: Remove file-reading things to symfile.h.
5311 * symtab.c: Remove file-reading things to symfile.c.
5313 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
5314 to decode i960 fault types.
5316 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
5317 target.c: Change type of the "resume" function from int to void,
5318 since its result was never used.
5320 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
5322 * main.c: Replace "stupid" with "caution"; you now "set caution
5325 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
5327 * infcmd.c (do_registers_info): Call val_print to deal with the
5328 byte order of the registers being printed. FIXME, this makes
5329 the formatting of the output uglier.
5331 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
5332 defined, call it for signals the debugger doesn't itself use.
5333 The i960 uses this for more detailed fault information.
5335 * remote.c (remote_open): If arg is null, print help rather than
5338 * sparc-xdep.c (register_valid): Avoid declaring size, since
5339 various modules will think of various sizes depending on the
5340 architecture of their tm-file. FIXME, we need protection against
5341 actually entering one of those modules, which would clobber
5342 storage if not for the target architecture compiled into gdb.
5344 * stack.c (up_command, down_command): Always print the frame
5346 (up_silently_command, down_silently_command): New commands
5349 * i960-pinsn.c (reg), i960-tdep.c: Lint.
5351 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
5352 more parameters than it used to.
5354 * findvar.c (registers): Increase slop to 256 bytes, which should
5355 protect us against even most RISC machines with large register
5357 (locate_var_value): Move declaration inside related ifdef.
5359 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
5360 throughout, to avoid throwing away buffered input from the board.
5361 (nindy_wait): Supply_register takes addr_of_value, not value.
5362 (i960_print_fault): Renamed from i80960_fault.
5363 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
5364 (nindy_store_registers): Avoid regs_changed stuff, just stuff
5366 (nindy_create_inferior): Don't bother to write PC_REGNUM since
5367 we can set the PC in the call to proceed(). Unpush nindy_ops
5368 before pushing it on top, to avoid message to user. Eliminate
5369 commentary from Unix machines that just misleads here.
5370 (reset_command): Fix error message to suggest target command.
5372 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
5374 Release 3.92.5 as frozen.
5376 Stabilize the merged release...with help from lint, Saber C,
5379 Everywhere: Add include files needed to declare return types
5380 of functions called.
5382 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
5384 * breakpoint.h: Add undeclared breakpoint functions, and some
5385 functions for display handling since I couldn't think of a better
5388 * breakpoint.c (insert_breakpoints): Make code for disabling
5389 shared library bkpts more likely to work. It's used when we
5390 rerun a program and stop before the shared library has been
5392 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
5393 cast from pointer, so it squeezes through catch_errors.
5394 (bpstat_stop_status): Fix logic broken some time ago. We now
5395 always create a bpstat if the stop address matches a breakpoint,
5396 even if we don't stop there -- just like the old code used to do
5397 before I got my fingers into it (sigh).
5398 (breakpoint_1): Print "ignore count" after "stop only if"
5399 condition, since that's how it actually works.
5400 (mention): Handle watchpoints as well as breakpoints.
5401 (watch_command): use set_raw_breakpoint and mention to do most
5402 of the work (and initialize all the fields!). Only pass one
5403 arg to parse_c_expression, since that's all it takes.
5405 * command.c (not_just_help_class_command): Rename arg to args
5406 since we ignore "unused argument" warnings on vars named "args".
5407 inflow.c (child_terminal_info): ditto.
5408 infptrace.c (kill_inferior): ditto
5409 main.c (catch_errors, version_info, quit_command, pwd_command,
5410 source_command, dump_me_command, editing_info,
5411 set_history_size_command, set_history, show_history,
5413 stack.c (locals_info): ditto
5414 target.c (target_files_info): ditto
5415 valprint.c (set_input_radix, set_output_radix): ditto
5417 * core.c: Remove old variables for handling core and exec file
5418 sections (data_start, data_end, stack_start, stack_end,
5419 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
5420 text_end, exec_data_start, exec_data_end, text_offset,
5421 exec_data_offset, data_offset, stack_offset). They're
5422 superseded the more general build_section_table and
5424 (get_exec_file): Mention the `file' command.
5425 (read_memory_check): Rename to memory_error, and only call it
5426 in the case of an actual error.
5427 (read_memory, write_memory): call memory_error.
5428 (core_fetch_registers): Register section name is ".reg".
5430 coredep.c: Remove a bunch of crud now that all this file does
5431 is pull the registers out of a core file.
5432 (fetch_core_registers): Rewrite to actually work, I hope.
5434 dbxread.c: Use a.out.gnu.h, not system a.out, now.
5435 Replace index() with strchr(). Remove all the pre-BFD macro
5436 definitions for accessing the symbol file.
5437 (struct dbx_symfile_info): Encapsulate the information that
5438 dbx_symfile_init needs to pass to dbx_symfile_read in this
5441 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
5442 dbx_symfile_discard): Rearrange symbol file reading to divide
5443 the format-specific part from the format-independent part,
5444 leaving the format-independent part such as file name expansion
5445 and opening in symtab.c. This replaces
5446 partial_symbol_file_open and partial_symbol_file_read.
5447 Symbol_file_read, add_file, add_file_target_command,
5448 add_file_addr_command move to symtab.c. Pass an explicit
5449 "mainline" flag for when reading the main symbol table, rather
5450 than relying on the offset address to be zero or nonzero.
5452 (dbx_symfile_read): Don't allow void *'s to be printed as
5454 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
5455 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
5456 macro" debug version really work.
5457 (read_dbx_symtab): Remove unref'd parameter inclink.
5458 Avoid swapping N_SLINE symbols, for speed.
5459 Merge N_TEXT!N_EXT case with the other external symbol
5460 definitions' case. Add comments.
5461 (start_psymtab): Allocate the symfile name in the psymtab on
5462 the psymbol_obstack, rather than using the caller's storage.
5463 (end_psymtab): Only allocate a dependencies list if there are
5465 (psymtab_to_symtab_2): Use BFD when reopening file to read
5466 its symbols for real.
5467 (read_struct_type): Add FIXME comments where it needs work
5469 (read_huge_number): Add FIXME about overflows.
5470 (read_range_type): Add FIXME about comparing a long to 1<<32.
5472 * coffread.c: Minor changes to move things closer to the new
5473 regime with symtab.c and dbxread.c Major work is still needed
5476 * exec.c (exec_file_command): Remove old variables (see core.c
5478 (xfer_memory): If memory transfer is right at the end of a
5479 section, don't lose.
5481 * findvar.c (get_saved_register): If value is in a real
5482 register, LVAL is lval_register, not lval_memory.
5484 frame.h: Declare print_sel_frame and record_selected_frame.
5486 gdb-int.texinfo: New file, for GDB internals documentation.
5487 Very simple, unformatted doc of cleanups is there for now.
5489 gdbcore.h: Remove obsolete variables that described a.out
5490 section addresses and offsets. (See core.c above.)
5491 Declare fetch_core_registers and registers_fetched.
5493 getopt.c: Declare char *alloca(); even on SPARC.
5495 infcmd.c (run_command): Call target_kill rather than
5497 (step_command, next_command, stepi_command, nexti_command):
5498 Declare from_tty parameter even though we don't use it.
5499 (run_stack_dummy): argument BUFFER is a char array, not
5500 a pointer to REGISTER_TYPE.
5501 (finish_command): using_struct_return needed a value *,
5502 not a struct symbol *.
5504 * infptrace.c (child_xfer_memory): To avoid dependency on
5505 where sections are in memory, try PT_WRITE_D and if that fails,
5506 try PT_WRITE_I. Most Unixes don't care which you use.
5508 * infrun.c (step_resume_break_shadow): Change to array to
5509 match other breakpoint shadow storage.
5510 (clear_proceed_status): Pass address of bpstat to
5511 bpstat_clear, not the bpstat itself.
5512 (child_create_inferior): FIXME comment about if the child
5514 (start_inferior): Remove old function.
5515 (child_open): Use target_kill rather than kill_inferior.
5516 (wait_for_inferior): Ditto.
5517 (insert_step_breakpoint, remote_step_breakpoint): Use
5518 new step_resume_break_shadow.
5520 * inftarg.c (child_wait): If all child processes die,
5521 pretend that the one being waited for exited with signal 42.
5523 * main.c (command_line_input): When scanning for comments,
5524 don't coredump on unclosed quotes.
5525 (quit_command): Use target_kill rther than kill_inferior.
5526 (_initialize_main): Rename class_user from "user" to
5529 * printcmd.c (print_command_1): Initialize "fmt" if no format
5530 is specified by the user.
5531 (print_frame_args): Only add to args_printed if we are
5532 actually fetching args from the stack (avoiding undefined
5534 (_initialize_printcmd): Remove bogus \{ from string.
5536 * remote-eb.c (eb_open): Avoid coredump on no argument.
5538 * remote-nindy.c: Bring out of Intel environment into new
5539 target environment. Remove all conditional compilation on
5540 I80960. Massive hacking throughout.
5541 (nindy_xfer_inferior_memory): New routine stolen from
5543 (nindy_create_inferior): New routine pieced together, probably
5544 not quite working yet.
5545 (nindy_ops): New target_ops struct for nindy.
5547 * remote-vx.c: Use write_memory rather than target_write_memory
5548 to get error checking.
5549 (vx_add_file_command, vx_open): Use symbol_file_add rather than
5551 (vx_create_inferior): Use target_terminal_ours...
5553 * signame.c (_initialize_signame): Always initialize, since
5554 we need the table for things other than psignal.
5556 * solib.c (solib_add): Use symbol_file_add, not add_file.
5557 (solib_address): Return boolean result rather than struct
5558 pointer which nobody else knows the type of.
5560 * sparc-tdep.c, valops.c: Use write_memory rather than
5561 target_write_memory, to get error checking.
5563 * stack.c (locals_info, catch_info, args_info,
5564 get_selected_block, frame_command, up_command): Use
5565 target_has_stack, rather than have_inferior_p or
5568 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
5570 * symfile.h: New file, defining the interface between the
5571 generic and object-file-specific symbol reading code.
5573 * symtab.c: Move generic symbol-reading interface to symtab.c,
5574 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
5575 table to map BFD targets to symbol-reading modules in GDB.
5576 Change index to strchr.
5577 (lookup_struct_elt_type): Use error() rather than hand-made
5578 simulations thereof.
5579 (lookup_partial_symbol): Speedup slightly when length == 0.
5580 (symbol_file_add): New function.
5581 (symbol_file_command): Call it.
5582 (symfile_open, symfile_init): New function.
5583 (add_file_target_command, add_file_addr_command): moved from
5586 * target.c (target_command): use target_kill.
5588 * target.h (target_files_info): Don't declare, never called
5591 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
5592 files to determine stack end address.
5594 * valarith.c (value_x_binop, value_x_unop): Change error message
5595 to be more useful. Pass proper argument to value_struct_elt.
5597 * valops.c (value_assign): FIXME comment that long long
5598 bitfields will break here.
5600 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
5601 Update `make saber_gdb' to work better.
5603 * TODO: A woman's work is never done.
5605 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
5606 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
5607 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
5608 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
5609 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
5610 valops.c, valprint.c, exec.c: Lint.
5613 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
5615 Continuing Intel 960 port merge of GDB.
5617 * Makefile.dist: Merge i960 "nindy-share" files. Rename
5618 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
5619 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
5620 Wack over "make depend" so it handles files in subdirectories
5621 vx-share, nindy-share, bfd, and in the current directory.
5623 * blockframe.c (get_prev_frame_info): Remove fatal error
5624 if stack not defined.
5626 * core.c (core_open, core_detach): New functions that handle
5627 the old "core-file" command as "target core" and "detach" instead.
5628 (core_file_command): Call them.
5629 (core_xfer_memory): Use common routine xfer_memory.
5631 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
5632 dbxread now uses bfd for everything but symbol reading itself.
5633 BFD internals are used to drag out the relevant file offsets.
5634 (partial_symbol_file_open): Change args all around for BFD.
5636 * symtab.c: Rename "value" to "val" everywhere, so we can
5638 (symbol_file_command): New command, moved from dbxread.c
5639 and coffread.c. It uses BFD to read the file, then vectors
5640 based on its type, to dbx or coff symbol readers.
5641 * symtab.h: Extern a few vars for symbol_file_command.
5643 * target.h: Breakpoint takes a char * save area, not a char **.
5645 * valprint.c (val_print): When unpacking bitfields, offset
5646 the address in gdb of the value, if it is declared with a shorter
5647 type. Remove the last "runtime kludge test" of host byte order.
5649 * utils.c: Remove old my_bfd_read routine.
5651 * stack.c (frame_info): Use target_has_stack. Print program counter
5652 register's actual name rather than "pc", since it's called the
5653 "ip" (instruction pointer) on the i960 (sigh).
5655 * target.c (target_command): Add command for selecting a target
5656 type and calling its open routine. This is used for initiating
5657 communication with a particular target, in a generic way.
5659 * tm-i960.h: Update for modern gdb. Remove semicolons from
5660 various macros. Handle reading struct return convention, and
5661 error-out attempts to return structs with the "return" command.
5662 Be sure gdb doesn't think we know how to call functions in the
5665 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
5666 to i960_xxx in lower case.
5667 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
5668 not being defined yet.
5670 * remote.c (remote_open): Call start_remote to initialize
5671 wait_for_inferior during open.
5672 (remote_xfer_inferior_memory): Return length written rather
5675 * remote-vx.c (target_command -> vx_open): Use new generic
5677 * remote-eb.c, inftarg.c, exec.c: ditto.
5679 * infrun.c: Fix comments.
5680 (attach_program -> child_open): Use new generic target command.
5681 (wait_for_inferior): Clear saved register values before target_wait,
5682 so target_wait can set some of them if convenient.
5684 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
5685 Return success indicator, not void.
5686 (child_xfer_memory): Avoid fetching initial word if we'll
5687 overwrite it anyway.
5689 * infcmd.c (attach_command): Use new generic target open routine.
5690 (_initialize_infcmd): Update doc on attach and detach commands.
5691 (do_registers_info): Merge in a byte-order problem as a FIXME
5694 * findvar.c (find_saved_register): Avoid problem in current frame.
5695 (read_relative_register): Ditto.
5696 (write_register): Convert byte order on the way out.
5698 * exec.c (file_command): Add.
5699 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
5700 (xfer_memory): Common function between core_xfer_memory and
5702 (exec_xfer_memory): Use it.
5704 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
5706 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
5707 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
5708 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
5710 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
5712 Merge Intel 960 port of gdb, continuing...
5714 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
5715 symbol_file_command): Pass from_tty arg to hush 'em up.
5717 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
5718 Add magic numbers for 960 COFF format.
5720 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
5722 Merge Intel 960 port of gdb, from Intel "1.2" release.
5724 CHANGE_LOG entries from their port, which was based on
5727 Thu Sep 6 11:02:22 PDT 1990
5728 Remove temp file if download is interrupted.
5730 Wed Aug 1 09:08:33 PDT 1990
5731 Now uses binary protocol to talk to NINDY.
5732 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
5733 Times out after 5 seconds when trying to talk to NINDY.
5735 Tue May 29 12:54:49 PDT 1990
5736 Added variable baud rate (-b switch).
5737 Source code reorganization.
5739 Thu Apr 26 11:09:55 PDT 1990
5740 More cleanup of batch mode; specifically, execute "-s", "-e", and
5741 "-se" switches as soon as they are encountered on the invocation line.
5743 Fri Apr 20 13:47:15 PDT 1990
5746 Thu Apr 19 09:54:28 PDT 1990
5747 Add 'reset' command.
5749 Wed Apr 18 09:48:07 PDT 1990
5750 After opening remote tty, wait for 1 second to go by without input
5751 from it before trying to talk to NINDY (fixes problems with the
5752 Heurikon HK80/V960E).
5754 Mon Apr 4 16:33:05 PDT 1990
5755 Some output was not being suppressed in 'batch' mode.
5757 Thu Mar 22 15:31:11 PST 1990
5758 Ask user if old symbol table should be deleted when new file is
5761 Allow user to run a program downloaded before gdb960 was brought up.
5763 Correct "exec-file" help message for i80960 context.
5765 Correct bug in calculating user space address: could occasionally
5766 corrupt user program.
5768 Make sure to zero low-order bits in rip's because of bug in 960CA
5769 A-step part: could cause operation faults when "next"ing across
5772 Correct bug that made it impossible to get source line numbers for
5773 code loaded at addresses higher than 0x7fffffff.
5775 Wed Jan 10 12:43:22 PST 1990
5776 Open remote tty for exclusive use.
5778 Fri Jan 5 12:14:42 PST 1990
5779 Correct disassembly (CA manual was right after all):
5780 opcode for sysctl is 0x659
5782 Mon Oct 23 12:03:04 PDT 1989
5783 Use G960BASE and G960BIN environment variables to find 'sx' utility.
5785 Mon Oct 16 14:15:09 PDT 1989
5786 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
5788 Mon Oct 2 15:56:31 PDT 1989
5790 Added 960CA disassembly support.
5792 To simplify maintenance:
5793 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
5795 - eliminated opcode.h: incorporates tables into i960-pinsn.c
5796 - moved 960-specific routines from i960-pinsn.c to i960-md.c
5797 - made disassembly interface identical to that in gdmp960.
5801 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
5803 * target.h: Allow targets to stack. Add target_has_memory,
5804 _registers, etc. Restructure memory access and "info files"
5805 to walk the target stack.
5806 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
5807 target.c: Change tables to match target.h.
5808 * inflow.c (child_mourn_inferior): pop child_ops.
5809 (generic_mourn_inferior): Use new has_stack flag.
5810 * infptrace.c (child_xfer_memory): New memory regime.
5811 * inftarg.c (child_files_info): New "info files" regime.
5812 * remote-eb.c: New memory regime, new info files.
5813 * remote-vx.c: New memory regime, new info files. Now use
5814 separate targets for VxWorks attachment to machine, and
5815 actually running a process under VxWorks, since one has
5816 stack & execution & regs and the other doesn't.
5817 * remote.c: New memory regime, new info files.
5818 * sparc-xdep.c (fetch_core-registers): New memory regime.
5819 * target.c: New routines and support for stacked targets,
5820 new memory regime, new info files regime.
5823 Generalize section handling for an arbitrary number of sections,
5824 including use of the new BFD (binary file) library.
5825 * gdbcore.h: Add struct section_table.
5826 * exec.c (build_section_table): Iterate all sections and
5827 record what gdb needs to know about them.
5828 (exec_command): Use it.
5829 (exec_xfer_memory): Use the table.
5830 (exec_files_info): Print the table.
5831 * core.c (core_file_command, core_xfer_memory, core_files_info):
5833 * source.c (find_source_lines): Use bfd_get_mtime.
5834 * dbxread.c: Quick changes to make it compile with new BFD.
5835 * utils.c (error): Avoid using bfd_error in generic routines.
5837 * core.c (core_fetch_registers): Get from the ".regs" section of
5839 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
5841 * inferior.h (attach_flag): Export.
5842 * infcmd.c (run_command): use new target_create_inferior.
5843 * infrun.c (child_create_inferior): Don't return result.
5844 * Makefile.dist (VERSION): 3.91.4.
5846 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
5848 * breakpoint.c (bpstat_num): Handle breakpoints which have
5849 since been deleted, such as temporary breakpoints.
5850 infcmd.c (program_info): ditto.
5852 * core.c (core_file_command): Display the frame where the core
5857 * remote-vx.c (target_command): Merge in target command from
5858 targ-vx.c. A few other cleanups.
5860 * TODO, Projects: Lots more stuff to do...
5862 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
5864 Massive changes to wall off the remote-debugging interface
5865 behind a function vector. The port to handle VxWorks targets
5866 is also part of this.
5868 All files: Replace references to renamed functions,
5869 remove references to remote_debugging, remove references to
5870 have_include_file, have_core_file in favor of target_has_stack,
5871 target_has_memory, etc.
5873 * Modularize the breakpoint interface.
5874 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
5875 a breakpoint instruction.
5876 breakpoint.c: struct breakpoint's shadow_contents now sized as
5878 (insert_breakpoints): Vector to target to install breakpoints.
5879 (remove_breakpoints): Vector to target here too.
5880 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
5881 sparc-tdep.c (single_step): Use new breakpoint interface for
5882 the single-step breakpoints.
5883 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
5884 New file, contains routines to insert and remove breakpoints by
5885 reading out the old contents and later replacing them. This is
5886 how ptrace breakpoints work, and many remote systems as well.
5888 * tm-vxworks68.h: New config file, overrides a few things for
5889 Wind River's preferences.
5891 * target.h: New file, for transfer vector used to talk to the
5892 inferior (child, attached, core, exec, remote, etc). All accesses
5893 to the thing being debugged should come through these vectors.
5894 target.c: New file, routines to handle transfer vector.
5895 (various files): Add transfer vectors XXX_ops for the various
5896 targets and pseudo-targets (core files, etc) we support.
5898 * breakpoint.c (bpstat_stop_status): Further explorations of
5899 watchpoints and why things don't work all the time.
5900 (bpstat_alloc): New fn to allocate a bpstat and chain it.
5902 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
5903 the local gdbinit if it doesn't already have it.
5905 * core.c (core_ops): add and install.
5906 Allow core debugging without exec file.
5908 * dbxread.c (free_and_init_header_files): Merge two fns.
5909 (end_symtab): Free named symbol table when a new version comes in.
5910 (read_dbx_symtab): Relocate all kinds of symbols with base
5911 address. First step toward handling different text, data, bss
5913 (add_file_addr_command): Renamed add_file_command.
5914 (add_file_command): Vector to remote handler.
5915 Add "load" as an alias for "add-file" command.
5917 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
5918 non-returning functions.
5920 * exec.c: Add exec_ops, and push it as a target when an exec
5923 * infcmd.c (run_command): Pass executable file name and arg list
5924 separately when starting an inferior. Permit "run" when no exec
5925 file is specified, for VxWorks.
5926 (detach_command): Move to child_detach in inftarg.c.
5928 * inftarg.c: New file. Unix-child-specific routines, and the
5929 child_ops structure.
5931 * inferior.h (registers): Export "registers" as the way for
5932 target dependent register handlers to find gdb's local copy of
5933 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
5934 since it is now used by places that want wait_for_inferior to
5935 handle the grunge but want to see every trap from the inferior.
5937 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
5938 Eliminate remote_debugging hooks in terminal handling.
5940 * infrun.c: Replace start_inferior with child_create_inferior.
5941 Move all the hair of Unix shells and ptrace idiosyncracies into
5942 child_create_inferior, so remote handlers don't have to deal.
5943 Remove running_in_shell. Rename stop_after_attach to
5944 stop_soon_quietly, and use it in a few other places where we want
5945 to just call wait_for_inferior and get control back on the first
5946 trap. trap_expected now never takes a value > 1.
5947 (init_wait_for_inferior): Initialize static vars when a new
5950 main.c (gdbinit): Add new hook for .gdbinit file name, let
5951 it be overridden by config files as GDBINIT_FILENAME.
5952 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
5953 Both of these are used for VxWorks gdb.
5955 mcheck.c: rename include file "gmalloc.c" to avoid problems
5956 with system include file "malloc.c".
5958 param-no-tm.h: New include file, same as param.h but does not
5959 include the default "tm.h" file. This is used in files where
5960 the target is known, e.g. remote-eb.c or sparc-xdep.c.
5962 param.h: Now just a shell that includes tm.h and param-no-tm.h.
5964 remote-vx.c: New file, VxWorks remote debugging support. Uses
5965 RPC routines that are shared with the target system, in directory
5968 remote.c: Vectorize remote interface.
5970 source.c: Globalize source_path, and make an alias "l" for "list"
5971 since we now have the "load" command.
5973 sparc-xdep.c: Use new param-no-tm.h.
5975 symmisc.c (free_named_symtab): Add new function from Wind River.
5976 However, ifdef it out for now while we think about what it should
5979 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
5981 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
5982 non-Unix-children handle this with their own code in the target
5985 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
5986 source and target lists. Add vx-share to default list of include
5987 directories. Add new files to src and target lists: mem-break,
5988 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
5989 ${srcdir} versions of munch and createtags are used.
5991 * valops.c (find_function_addr): Split out of call_function.
5992 (call_function_by_hand): Rename call_function; this function
5993 calls functions in the target by laboriously patching the target
5994 word-by-word with the right stack, args, regs, etc.
5997 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
5999 Handle AMD 29000 a bit better.
6001 * remote-eb.c (readchar): Mask received char log to make it readable.
6002 (remote_start): Pass arguments down to executing program.
6003 Make startaddr unsigned.
6004 infrun.c (start_inferior): Accept args, pass them to
6006 infcmd.c (run_command): Pass args down to start_inferior.
6008 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
6009 the target object file format.
6010 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
6012 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
6013 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
6015 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
6017 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
6018 * TODO: We did a few things, we have more to do though.
6020 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
6021 * inflow.c (inferior_died): Clear deferred stores.
6023 * Debug problems with dummy frames and calls to the inferior.
6024 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
6025 * sparc-tdep.c (do_restore_insn): Simplify.
6026 (sparc_frame_find_saved_regs): Simplify and fix what we find.
6027 (sparc_push_dummy_frame): Simplify and fix what we push.
6028 (sparc_pop_frame): Slightly more hair here, deciding whether
6029 we are restoring a saved PC or returning to a return address in %i7.
6030 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
6032 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
6033 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
6034 * obstack.h (chunkfun): ditto.
6035 * defs.h (xmalloc, xrealloc): ditto
6037 * utils.c (quit): Grab the terminal from the child if necessary.
6039 * inflow.c (term_status_command): Rename to term_info, change
6042 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
6043 (is_delayed_branch): Speed up.
6044 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
6045 Still missing some float ops, and needs testing.
6047 * Support for input and output radixes other than base 10
6048 * defs.h (input_radix, output_radix): Declare.
6049 * expread.y (yyparse, parse_number): Handle changes of input
6050 radix, and ambiguous names-or-numbers in radixes >10.
6051 * printcmd.c (print_scalar_formatted): Print formatted hex
6052 numbers in varying column widths.
6053 * valprint.c (val_print): Use output_format to print scalar ints.
6054 (set_input_radix, set_output_radix, set_radix): Create.
6055 (set_output_radix): Set output_format from output_radix.
6056 (_initialize_valprint): add `set radix' but leave the others off.
6058 * main.c (execute_command): Let stupid questions be turned off.
6059 (_initialize_main): Handle "set stupidity", etc.
6061 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
6062 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
6064 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
6066 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
6067 bfd stuff is still screwed up, but with some manual work, it
6070 * breakpoint.c (bpstat_do_actions): Start over if a command
6071 proceeds the inferior, since the inferior will have stopped and
6072 will need to have its new stop-actions taken care of.
6074 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
6075 compiler fits, simplify it.
6077 * gdb.texinfo (directory command): Doc new dir command.
6078 source.c (directory_command): "dir" now puts things on the front
6079 of the path, moves dups up front, and handles multiple names
6080 on the command line, inserting each one in order. It also
6081 blows away cached line and full_filename info.
6083 * stack.c (backtrace_command): Skip "more stack frames follow"
6086 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
6087 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
6088 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
6089 The only odd one was Gould NP1, which had defined vprintf to
6092 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
6093 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
6094 variable, inspect_it.
6095 valprint.c (print_string, val_print): Use the global inspect_it
6096 to indicate whether to print in Epoch style or normal style.
6098 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
6100 * printcmd.c (call_command): add an alias for the "print" command
6101 which runs expressions and doesn't print the result if void.
6102 (print_command_1): implement it.
6104 * command.c: Remove #if 0'd code. Initialize all the fields
6105 in add_cmd (). Rename do_nothing_command to
6106 not_just_help_class_command, and make it externally visible.
6107 command.h: add user_commands to struct.
6108 * main.c (define_command): Don't overload c->function with a char
6109 string as well as a function pointer.
6111 * eval.c (evaluate_subexp): Reinstall tiemann changes to
6112 calling convention of value_struct_elt () that got dropped in
6115 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
6116 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
6118 * tm-sparc.h (POP_FRAME): replace some constants with defines.
6120 * sparc-xdep.c (store_inferior_registers): defer stores to regs
6121 until a good time (e.g. when we are about to run the child),
6122 saving ptrace calls.
6123 * infrun.c (proceed): handle DO_DEFERRED_STORES.
6124 * tm-sparc.h: define DO_DEFERRED_STORES.
6126 * sparc-xdep.c (store_inferior_registers): when storing float
6127 registers, don't store stack regs too. When storing the SP,
6128 however, DO store the stack regs too. This fixes a bug in which
6129 the dummy frame is not recognized when a call_function finishes,
6130 because its frame pointer (in the stack regs) was never
6132 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
6133 even though we don't know how to read them from an inferior.
6134 valops.c (call_function): Comment about storing SP.
6136 * infrun.c (save_inferior_status): Save away the original bpstat
6137 chain so it can be restored later. Install the copied version for
6138 use by whoever saved the status. It will be blow away by
6139 restore_inferior_status, and the original chain restored. This is
6140 important for people who have pointers into the original.
6142 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
6143 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
6144 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
6147 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
6149 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
6150 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
6151 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
6153 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
6155 * Merge Mike Tiemann's multiple inheritance changes from Sun.
6156 Store the baseclasses in a type struct starting from array element
6157 0 rather than from the unusual array element 1.
6159 dbxread.c: the above.
6160 (virtual_context): Add
6161 Read new debug information about which virtual function table
6162 a virtual function is from, and store it in fn_field.fcontext.
6164 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
6165 TYPE_FN_FIELD_STATIC_P.
6167 symtab.c: the above.
6168 valops.c: the above. Handle pointer casts of object *'s.
6169 (search_struct_method): Add.
6170 (value_struct_elt): First arg is now a pointer to a value, and is
6173 valprint.c: the above.
6174 values.c (value_virtual_fn_field): Add type arg. Handle
6175 offsetting to the proper object when calling virtual fns.
6177 (baseclass_addr): Add valuep arg.
6179 * README: Document the current state of BFD config (missing).
6180 * TODO, ChangeLog, Makefile.dist: Roll version.
6181 * WHATS.NEW: Add summary of changes since 3.5.
6183 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
6185 * dbxread.c (read_struct_type): Clear bit vectors whenever
6187 symtab.c (B_CLRALL): define.
6189 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
6190 using == rather than =. Huh... This fixes the dreaded problem
6191 wherein builtin_type_int becomes TYPE_CODE_FLT.
6193 * core.c (info_files): Show the inferior pid.
6195 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
6196 already knows how to look in the source directory.
6198 * Remove psymtab hair from many places. Remove duplicated code
6199 for searching symbol tables. Hide psymtabs from most places.
6200 Make it fast to get from a psymtab to its symtab.
6202 blockframe.c (blockvector_for_pc): Remove psymtab hair.
6203 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
6204 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
6205 dbxread.c: export psymtab_to_symtab, make it work if called N times.
6206 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
6207 new symtab completely. New psymtabs get symtab pointer
6208 initialized to zero. Remove MI warning printf.
6209 symtab.h: Comments. Add psymtab to symtab pointer.
6210 (PSYMTAB_TO_SYMTAB): New macro.
6211 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
6212 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
6214 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
6216 (print_frame_info): Avoid special-casing symbols that have not yet
6219 * source.c (open_source_file): Quick path if we have already
6220 located the source file by its full name.
6222 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
6223 find_pc_psymtab. When a name is found in the misc function
6224 vector, search the symbol table for its mangled name, not the
6225 name that the user typed.
6227 * bfd.h: Fix missing comment terminators, make #endifs match.
6229 * valarith.c (value_less): Handle unsigned int comparisons.
6230 Add FIXME about pointer compares, which assume host and target
6231 pointers are the same.
6233 * command.c (do_nothing_command): lint
6234 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
6235 fix comments on debug symbol format for visibility. Actually set
6236 visibility of symbols.
6237 main.c (echo_command): lint; use <readline/history.h>.
6238 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
6239 obstack.h (_obstack_blank): Rearrange pointer math to avoid
6240 pointing past end of allocated memory; saber complains.
6241 obstack.h: Declare the external functions that we use.
6242 valarith.h: use <string.h>
6243 solib.c (solib_add): lint.
6245 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
6247 * main.c (initialize_main): Default info_verbose to off, now that
6248 symbol reading is fast.
6249 (quit_command): Avoid clobbering exec_bfd while quitting.
6251 * Initial BFD (binary file diddling library) merger:
6252 coffread.c: Change AOUTHDR to struct exe_hdr.
6254 core.c: initialize initialized data at compile time.
6255 (core_file_command): Move from coredep.c, convert to bfd.
6256 (xfer_core_file): Convert to bfd.
6257 exec.c (exec_file_command): use bfd routines.
6259 mips-tdep.c: Remove exec_file_command and friends.
6262 * coredep.c: (fetch_core_registers) Convert core_file_command to
6263 fetch_core_registers.
6264 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
6266 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
6267 (my_bfd_read): More bogosity, which I don't think we call.
6268 (program_name): Remove this atrocity asap!
6270 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
6273 values.c: allocate_repeat_value was not clearing the
6274 optimized_out field.
6275 (value_static_field): minor stylistic fix (wrong macro was used).
6276 valops.c (value_struct_elt_for_address): didn't work for C++
6279 * signame.c (_initialize_signame): Initialize signal names once.
6281 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
6282 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
6283 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
6285 * remote-eb.c: Support user-settable baud rates on the serial port.
6287 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
6289 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
6291 * tconfig/sun3os4: Remove warning about native assembler,
6292 since it also occurs in the xconfig file.
6294 * findvar.c (registers): Allocate some slop after `registers'
6295 to prevent stray accesses from trashing the next variable.
6297 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
6298 on the sun-3, by changing the #ifdef from `sun3' (which is not
6299 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
6300 vars, which happened to follow `registers' in the executable.
6302 * readline/history.c (history_search): Heed gcc-2's advice
6303 and parenthesize && inside ||).
6305 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
6306 tm-29k.c: Insert FSF copyright headers.
6308 * remote-eb.c: Better comments.
6310 * Makefile.dist: Update to 3.91.6.
6311 * TODO: note PREPARE_TO_STORE problem.
6313 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
6315 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
6317 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
6319 * infrun.c (wait_for_inferior, at end): Don't set up
6320 prev_* if the inferior no longer exists.
6322 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
6323 CANNOT_EXECUTE_STACK.
6324 valops.c (call_function): Use it.
6326 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
6328 * inferior.h (PC_IN_CALL_DUMMY): New macro.
6329 infrun.c (wait_for_inferior, 2 places): Use it.
6331 * values.c (value_being_returned): Only use
6332 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
6334 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
6335 right thing for remote-eb.c.
6337 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
6338 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
6340 * blockframe.c: Put get_frame_saved_regs inside #if !defined
6341 (FRAME_FIND_SAVED_REGS).
6343 * findvar.c ({fetch,store}_registers): Check for
6344 REMOTE_{FETCH_STORE}_REGISTER macro.
6346 * findvar.c (get_saved_register): Add argument lval and
6347 change meaning of argument addr.
6348 findvar.c: Change calls to get_saved_register to reflect
6349 new calling convention.
6350 valops.c (value_assign): Use get_saved_register instead of
6351 find_saved_register.
6353 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
6355 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
6356 an (uninitialized) pointer to one. Use "&" when passing it
6359 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
6361 * coffread.c (getfilename): Use DGUX x_offset and x_name if
6364 * coffread.c (symbol_file_command): Put semicolon after
6366 Put safe_to_init_tdesc_context in #if defined (TDESC).
6367 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
6368 coffread.c: #include <sys/stat.h>.
6369 (read_coff_symtab): Typo: in_source_files -> in_source_file.
6370 Add missing ')' in check for "lc%" and friends. Remove
6372 Declare read_one_sym() at top of file.
6373 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
6374 MC68WRMAGIC can have the same value without causing a duplicate
6377 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
6379 * Allow a Makefile to be built without building the
6380 tm and xm file links that screw up builds in subdirectories.
6381 This is done with `config.gdb none', then you can do things
6382 like `make gdb.tar.Z'.
6383 * tconfig/none: Config file for no target system
6384 * xconfig/none: Config file for no host system
6385 * config.gdb: If no TM or XM files are called out by the
6386 host or target file, don't make links for them.
6388 * cplus-dem.c: Add documentation.
6390 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
6391 simple error, so the user's gdb doesn't crash due to some object
6392 file problem (e.g. somebody is rebuilding the file out from under
6395 * printcmd.c (print_address_symbolic): demangle the symbol.
6397 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
6398 Motorola copyrights in it. Make "make gdb.tar.Z" work.
6399 (alldeps.mak): sort and uniq all results from this; duplicates
6400 hose gdb.tar.Z link building. Remove RCS files from
6401 tconfig and xconfig. Add config files for sun386. Add
6402 a few odd files to OTHERS and HFILES.
6404 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
6406 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
6407 Roll version number to 3.91.5. Make lint work in bindir.
6409 * README: Document cross-debugging and new file structure.
6411 * blockframe.c: Lint. Include "value.h" to declare read_register.
6412 (find_pc_partial_function): remove duplicate line.
6414 * command.h: Lint. Declare error_no_arg and dont_repeat.
6416 * tm-news.h: Remove inadvertently duplicated stuff.
6418 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
6419 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
6421 * config.gdb: Allow `config.gdb host target' form. Clean
6422 up previous change that printed bogus messages when you just said
6425 * core.c: #include "command.h" for lint.
6428 * main.c: Remove some casts of enums. Lint.
6435 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
6437 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
6438 read it from memory. This will allow us to save ptrace calls
6439 eventually. Changed caller single_step too.
6441 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
6442 that we aren't going to use, saving many ptrace calls, especially
6443 when watchpointing or single stepping. Use some #define's for
6445 (store_inferior_registers): Ditto.
6446 (core_file_command): Use some #define's for constants.
6448 * tm-sparc.h: Add #define's for some register numbers, so we
6449 can eliminate the use of random constants in sparc-xdep.c.
6451 * stack.c (frame_command, print_frame_info, up_command,
6452 down_command) Remove frame_changed, since it
6453 causes a bug and doesn't seem to do anything useful. In some
6454 places it was used as a flag, in others as a stack level (?).
6456 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
6457 default is to use the portable (vprintf) version rather than the
6459 * xm-news.h (MISSING_VPRINTF): Add.
6461 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
6463 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
6465 * Remove stuff that forces -Bstatic linking of gdb, and warnings
6466 about linking debugged programs -Bstatic in the sun?os4 config
6467 files in tconfig and xconfig subdirectories.
6469 * main.c (main): Remove unreached exit(0) now that we exit
6472 * Create TODO file for online bug list. There are too many
6473 "little" bugs to keep track of on paper.
6475 * Change Projects file to refer to bug-gdb@cygnus.com
6476 rather than kingdon@ai.
6478 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
6480 * Makefile.dist (VERSION): 3.91.4 now.
6482 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
6483 (condense_misc_bunches): Add sanity check that misc_count is
6484 the same as the number of symbols in the bunch.
6486 * coffread.c: rename init_misc_bunches. Pass an argument
6487 to condense_misc_bunches (a zero).
6489 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
6490 every time we are called; don't rely on our caller to do it.
6491 (add_file): Remove call to init_misc_bunches.
6493 * mipsread.c: Only warn, don't error, if unknown symbol types.
6494 This keeps an old gdb from falling on its face if it sees newly
6495 extended symbol info. Rename init_misc_bunches.
6497 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
6499 * Merge in changes from Per Bothner for DECstations and other
6500 MIPS stuff. The rest is Bothner speaking:
6502 The next message is a merger of Alessando Forin's mips port with
6503 mine. I've tried to use my good if biased judgment to get
6504 the best of both. It *does* need testing.
6506 Some of the changes are general, *not* mips-specific.
6509 Didn't believe in little-endian bit order.
6510 There are still inconsistencies about whether flags
6511 like BITS_BIG_ENDIAN are integer (#if ...) or
6512 boolean (#ifdef ...). I tried to paper over them.
6514 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
6515 Moved some misc_function code that was common to
6516 {dbx,coff,mips}read.c to symtab.c.
6517 In the process, I think I cleaned things up a bit.
6518 At the same time, moved obsavestring and obconcat to symtab.c.
6521 Removed obsolete condense_addl_misc_bunches (use
6522 condense_misc_bunches(1) instead).
6525 Needed to include <sys/dir>, at least on DECstations.
6527 valops.c, mips-tdep.c, tm-mips.h:
6528 Added PUSH_ARGUMENTS macro to support funny argument-pushing
6529 conventions (when STACK_ALIGN is insufficient).
6530 Needed on mips, where doubles need 8-byte alignment,
6531 but ints only need 4.
6534 Removed cruft that was not being used.
6535 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
6538 Print $ before register-names (I think that makes things a little
6540 Never print two instructions, even if one delays.
6541 Removed hex-disassemble set_cmd. (This is not mips-specific,
6542 so I think the argument is whether it is generally worthwhile or not.
6543 I'm inclined to think not, given how easy it is to
6544 convert between radixes in gdb.)
6547 This is basically Alessando's code.
6548 It doesn't use obstacks; I changed it to use obstacks
6549 in a few minor places where using malloc causes a
6550 memory leak. (Probably, more places could/should be changed.)
6551 I added record_misc_function where it was missing.
6552 In symbol_file_command and add_file_command, I tried
6553 to make the code consistent with more recent versions.
6554 Minor sylistic changes in parse_procedure.
6555 Make a .gdbinfo. psuedo-symbol point back to the real
6556 procedure symbol (using the isym field).
6559 This is basically from my port, but with a lot of details
6560 and a number of routines merged in from Alessando's version.
6561 I basically used my code "raw" backtrace (use heuristics
6562 from the actual code, rather than symbol table info) - though
6563 the idea is Alessandro's. I feel my code is a little cleaner
6564 here, particularly in being a little more flexible, such as being
6565 able to handle gcc-produced code (which it now can).
6566 It also doesn't do frame caching (which is not useful
6567 more recent gdb versions).
6568 I also used my code for push_/pop_dummy, more or less.
6569 I tried to incorporate AF's code for testing sigtramp
6570 while backtracing; I probably got it wrong.
6571 Added mips_print_register, which tries to scrunch as much
6572 information as possible on a screen...
6573 Removed the skip-prologue set_cmd. As with hex-disassemble (see
6574 under mips-pinsn.c), I don't see anything mips-specific here,
6575 and I don't see it being all that useful anyway.
6578 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
6579 Use more register names (rather than hard-cases numbers).
6581 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
6583 * Hack up 3.90.11 changes:
6585 * Makefile.dist (depend): parameterize $(GCC).
6586 Add solib.c and solib.o.
6587 (readline): Fix vpath for both absolute or relative SRCDIR.
6589 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
6590 Also, let the part I didn't understand at least compile so
6591 I can test the rest. FIXME.
6593 * dbxread.c: Fix thinko using strcmp.
6594 (init_psymbol_list): declare static.
6595 (partial_symbol_file_open): Comment cleanups better, avoid
6596 cleaning up the string table since the caller will do that.
6597 Move the stat for mod time into symbol_file_command, temporarily.
6598 (There should be a mod time for each symbol file, eventually,
6599 to control its rereading. FIXME.)
6601 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
6602 SunOS, which gives error for shared libs otherwise. (From
6603 Schaefer, probably FIXME needs work for portability.)
6605 * solib.c: Move #include "param.h" to work.
6606 Lowercase all the Uppercase Letters In the Messages.
6607 (find_solib): Clean up inferior_so_name for debug printouts.
6608 Allow no argument, to mean all shared libraries.
6610 * symmisc.c: include param.h to get CLEAR_SOLIB.
6612 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
6614 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
6615 to 3.90.11. ChangeLog entries below are from this.
6617 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
6621 * Makefile.dist (HFILES): Add tm-sunos.h.
6623 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6627 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
6629 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
6631 * sparc-opcode.h Added single-operand version of rett.
6633 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6635 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
6636 Put parens around gcc_p in expansion.
6638 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
6640 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
6642 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6644 * Changes for Sun shared libraries:
6645 blockframe.c (find_pc_partial_function): If a non-text symbol
6646 is found, set *address = pc - FUNCTION_START_OFFSET.
6647 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
6648 Disable breakpoints instead of giving an error.
6649 source.c (select_source_symtab): Initialize cs_pst.
6650 symmisc.c: Call CLEAR_SOLIB if defined.
6651 symtab.h: Make text{low,high} CORE_ADDR not int.
6652 (psymtab): New field addr.
6654 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
6655 (record_misc_function): Give correct type for N_DATA symbols.
6656 (condense_misc_bunches): do "misc_function_count = j" regardless
6658 Take code which is shared between symbol_file_command and
6659 add_file_command and put it into partial_symbol_file_{open,read}.
6660 Split add_file_command into add_file_command and add_file.
6661 Make psymtab_to_symtab read in the string table if the file
6663 Two new parameters to read_dbx_symtab and start_psymtab.
6664 tm-sunos.h: New file.
6666 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6668 * infcmd.c: Change cont_command to continue_command and "cont"
6671 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6673 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
6675 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
6677 * values.c (USE_STRUCT_CONVENTION): Check for structures of
6678 size 1,2,4,8 rather than size < 8.
6680 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
6681 as necessary, not just once.
6683 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
6685 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6687 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
6689 * tm-news.h: Add CALL_DUMMY_*.
6691 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
6693 * config.gdb: In list_host, list_target, use ${i}, not $i.
6695 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6697 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
6699 * sparc-opcode.h: Change all store floating-point state register
6700 instructions to have the right match & lose fields.
6702 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6704 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
6706 config.gdb: If srcdir != ., create readline directory and
6707 copy a makefile into it.
6709 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
6710 consistency with POSIX.
6712 * breakpoint.c (bpstat_stop_status): Disable watchpoint
6713 when we exit its exp_valid_block.
6715 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
6717 * Makefile.dist: Bump version to 3.91.3.
6719 * Clean up handling of breakpoint commands (somewhat).
6720 Prompted by Tiemann bug report "cont 10" doesn't work any more.
6722 inferior.h: Add breakpoint_proceeded to inferior status struct
6723 and globals; save it and restore it.
6724 (clear_breakpoint_commands): Cleanup, remove old #define.
6726 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
6727 (save_inferior_status, restore_inferior_status): handle it also.
6728 (proceed): Remove earlier code that set breakpoint_proceeded.
6729 It is now set only in clear_proceed_status.
6730 (clear_proceed_status): Cleanup, use bpstat_clear rather
6731 than clear_breakpoint_commands. No callers need the stop_bpstat
6732 between clear_proceed_status and proceed.
6734 infcmd.c: Add breakpoint_proceeded definition and comment.
6735 (cont_command, jump_command, signal_command): Move call to
6736 clear_proceed_status right next to call to proceed.
6738 breakpoint.c (bpstat_do_actions): Avoid clobbering our
6739 caller's argument while running down the chain of breakpoints.
6740 Use new variable "breakpoint_proceeded" to determine when
6741 a command that it executes moves the inferior past the
6743 (bpstat_clear): Handle NULL argument.
6744 (bpstat_clear_actions): Avoid useless call to
6745 breakpoint_auto_delete.
6746 (delete_breakpoint): Clean up bpstat's that are pointing to
6747 the deleted breakpoint from the stop_bpstat chain.
6748 (breakpoint_auto_delete): Simplify.
6750 * Clean up handling of EOF, error on stdin, etc. This was
6751 prompted by a network problem that caused gdb to go into an
6752 infinite loop filling up its malloc'd memory.
6754 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
6755 not clear_breakpoints_commands, which is now gone.
6756 (main): If command_loop returns (e.g. from EOF on stdin), do
6757 a quit_command (looping back to command_loop if quit_command
6758 doesn't really quit).
6759 (command_loop): check result from command_line_input and
6760 exit if it returns NULL, rather than passing the NULL to
6762 (gdb_readline): Free malloc'd result space before returning
6765 * utils.c (query): Handle C-d to mean "yes", just as if the
6766 input was not a terminal. Also avoid infinite loop if EOF
6767 occurs in mid-input-line before newline. This allows
6768 query to be used at EOF on stdin with reasonable results.
6770 * infrun.c (proceed): Set breakpoint_proceeded.
6772 * values.c (value_as_long): Avoid infinite recursion for enums.
6773 (_initialize_values): Fix typo in help msg (kingdon).
6775 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
6776 RL_LIB for linking. This allows -lreadline for linking
6777 and nothing for dependencies, once readline is a real library.
6779 * config.gdb: Jim Kingdon: give useful error message if the
6780 host or target type is not recognized.
6782 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
6783 it just defines it. Dumb, but deal with it.
6785 * Jim Kingdon suggests:
6786 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
6788 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
6790 * Makefile.dist (VERSION): Bump version # to 3.91.2.
6792 * Clean up Bothner's changes.
6794 * blockframe.c (clear_pc_function_cache): New function.
6795 * blockframe.c: remake cache_pc_function_* static.
6796 * dbxread.c (symbol_file_command): remove references to
6797 cache_pc_function_* variables.
6798 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
6799 * printcmd.c: Avoid kludging a global variable (addressprint)
6800 to avoid printing the address of a string twice. Instead,
6801 pass the format letter 's' down low enough that it can be seen
6802 to avoid this problem.
6803 (print_formatted): Pass format arg to value_print.
6804 (restore_addressprint): Remove function.
6805 (do_examine): Avoid hacking addressprint, cleanups and such.
6806 (print_frame_args): Add a comment to a Bothner change.
6807 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
6808 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
6809 to wipe out the values cached in blockframe.c.
6810 * symtab.c (find_method): Add comment saying how big you must
6811 allocate to be "big enough". Per being terse again.
6812 * valprint.c (val_print): Handle format letter "s" to print
6813 strings without addresses. Add comment to vtbl printing code
6814 which casts with wild abandon. Rearrange reference-printing
6816 @0xaddr: value (print w/addressprint)
6817 value (print w/~addressprint)
6818 @0xaddr (parameter lists w/addressprint)
6819 or nothing (parameter lists w/o addressprint)
6821 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
6823 * Merge more changes from Per Bothner:
6825 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
6826 annoying) that I tried to improve it. Here are my suggestions.
6828 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
6831 Do automatic de-reference when taking the address of a reference.
6833 Don't deref_ref when printing parameter lists.
6835 More attempts at treating refernences properly.
6837 In val_print, if deref_ref==0, don't print dangling " = ".
6839 Add COERCE_REF macro, which de-references an REF.
6841 * Merge changes from Per Bothner:
6843 * Fixed (Sony news)-specific configuration problems.
6844 * Fixed other problems with using vanilla pcc and libc (enum problems;
6845 assumption that vsprintf exists).
6846 * Some major speed-ups (finc_pc_partial_function now caches a match;
6847 parsing avoids duplicate symbol_lookup calls).
6848 * Changed handling of baseclasses (no longer use baseclasses field
6849 of struct type, use the first n_baseclasses fields instead).
6850 * Various minor changes/fixes, most C++-related.
6853 Cache the most previous match from find_pc_partial_function.
6854 (Save both low and high ends of matching function's pc range.)
6855 This speeds up the loop of infrun.c:wait_for_inferior quite
6856 a bit, and makes step/next commands much zippier.
6858 Added an enum->int cast (otherwise, some compilers barf).
6860 No longer set baseclass offset to 0, since multiple
6861 inheritance now mostly works.
6862 Added a number of casts, to shut up compiler warnings
6863 (after stabs where made enums, not ints).
6864 When discarding a symbol table (in symbol_file_command),
6865 must clear the cache introduced in blockframe.c.
6866 Don't convert $vtbl_ptr_type to vtbl any more.
6867 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
6868 Mask off sign bit emitted by g++ for virtual table offset.
6869 Set voffset to -1 (not 1) for static member functions.
6871 Changed parsing/lexing of names to avoid doing symbol lookup twice
6872 (once when lexing to determine symbol class, once for real).
6873 Now only call symbol_lookup once. Fields of 'this' win especially big.
6875 Subpress printing addr twice in the case of 'x/s addr'.
6877 lookup_basetype_type is no longer used.
6878 Add find_methods as recursive helper function to decode_line_1.
6879 This allows multiple inheritance to work.
6880 Also, once one or more matches has been found, do not look in
6881 base-classes. (Baseclass methods would be overridden, anyway.)
6883 Removed baseclasses array in struct type.
6884 Instead of using baseclasses[i], use fields[i-1].
6885 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
6886 Changed sign convention of voffset (previous was inconsistent).
6888 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
6890 Used to assume existence of vsprintf. Re-written to not need it
6891 if HAVE_VPRINTF is undefined.
6893 typecmp was too pessimistic. Made it less so.
6895 Don't print space after address.
6896 If vtable points to a misc symbol (with 0 offset), print it,
6897 since that indicates the actual class of the object.
6898 Changed ype_print_derivation_info to use new inheritance
6899 scheme (without baseclasses vector).
6901 In value_primitive_field, fixed some bugs left over from previous set of fixes.
6902 Also, changes needed because TYPE_BASECLASSES were removed.
6904 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
6906 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
6909 If there is no path set, and the symbols don't indicate what directory
6910 a file was compiled in, look in the current directory. But either
6911 a path or a known compilation directory will prevent this.
6914 Three independent bug fixes:
6915 * Remove the #if 0 block that breaks some stuff.
6916 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
6917 adapt gdb to either SunOS 4.0.* or 4.1.
6918 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
6921 Instantiate the class T when looking for methods in it. (Tiemann@sun)
6924 (type_print) Demangle the name being printed.
6925 (type_print_base) Handle botched demangling without coredump (tiemann).
6928 (check_stub_method): Document routine.
6929 (tiemann) fix bug for no-arg functions
6930 Avoid clobbering beyond end of malloc'd storage.
6931 Terminate the argument list properly.
6933 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
6935 * Changes merged by John Gilmore:
6938 In breakpoint_1, use new print_address_symbolic instead
6939 of find_pc_partial_function. (This forces use of assembler-level
6940 addresses, and avoids misleading non-mangled source-level names.)
6942 Generalize ansi argument such that -1 means skip arglist totally.
6943 Removed global variable print_ansi_qualifiers (which made
6944 code non-reentrant), in favor of extra explicit arguments
6945 to internal routines.
6947 Add new helper function print_address_symbolic.
6948 Use find_pc_misc_function instead of find_pc_partial_function
6949 (since we want assembler-level symbols here).
6951 Print unknown function as just "f (...)", not "f (...) (...)".
6952 Use new fputs_demangled explicitly.
6954 Fixed a typing violation (problem: value.h cannot be imported
6955 without renaming many variable in this file).
6956 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
6957 decode_line_1: Moved forward some never-reached code.
6958 Made decode_line_2 skip function prologues correctly.
6960 fputs_filtered should not demangle by default.
6961 Add new fputs_demangled to demangle on demand..
6963 Change value_struct_elt to use value_primitive_field (using recursive
6964 utility function search_struct_field). This allows foo.bar to work
6965 for multiple inheritance (so far only for data fields).
6966 Change check_field in the same way (recursive helper function
6967 to support multiple inheritance).
6968 (Note: there are more of these problems that I haven't fixed.
6969 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
6970 value_of_this: 'this' symbol name is now just "this", note "$this".
6972 Don't print static members.
6973 Avoid printing "members of <type>" if there are none.
6974 Simplified type_print_derivation_info by merging duplicate code.
6975 Remove useless blank lines in type_print_base (ptype command).
6977 Added declaration of new routine value_primitive_field.
6979 Added value_primitive_field which is generalized version of
6980 value_field that can handle multiple inheritance (non-zero offsets etc).
6981 Re-implemented value_field to call value_primitive_field.
6983 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
6985 * infcmd.c -- insert else to avoid 'delete env' coredump when you
6986 delete the whole environment. Karl Berry reported the bug.
6987 * source.c - fix openp to avoid //'s in filenames, which
6988 trigger an Emacs bug causing it to not be able to find files
6989 when running gdb in a window.
6990 * dbxread.c - zap the #if 0 that botches the add-file code.
6991 It seems to work a lot better without all the code commented out.
6993 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
6995 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
6998 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
7000 * Makefile - added a ${CFLAGS} to a couple of entries,
7001 added remote-sa.sparc.c
7002 * added remote.sa-sparc.c, a modification of remote.c
7003 which conducts a dialog directly with the SparcStation prom.
7004 * breakpoint.c, infrun.c, sparcdep.c added
7005 remote_insert_breakpoint(), and remote_remove_breakpoint()
7006 to breakpoint.c instead of directly writing breakpoint instructions.
7007 * sparcdep.c on remote_debugging,there is no need
7008 to remove signle step breakpoint instructions.
7009 * main.c added "-epoch" flag and "int epoch_interface" to main.c
7011 * printcmd.c - epoch interface sends lisp expressions to open up
7012 epoch windows on inspection.
7013 * valprint.c - added arrayprint, and addressprint and made adding
7014 format controls easier
7015 * wait.h added a couple of undef's because we were getting
7016 complaints about WSTOPSIG and WTERMSIG begin redefined.

7051 * values.c (check_stub_method): New function.

7086 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
7087 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
7088 when printing the type.
7090 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)

7112 step_resume_break_address != NULL, even if another_trap.
7113 If trap_expected and we enter sigtramp, then set up a
7115 If trap_expected is set when we hit the step_resume_break,
