1 Sat Dec 28 11:30:26 1991 Per Bothner (bothner at cygnus.com)
3 * dwarfread.c, coffread.c: Use INIT_CPLUS_SPECIFIC.
4 * symtab.c (gdb_mangle_name): Recognize and handle
5 constructors specially.
6 * symtab.c (check_stub_method): Test for failure from
7 cplus-demangle by calling error() instead of seg-faulting ...
9 Fri Dec 27 22:21:30 1991 Fred Fish (fnf at cygnus.com)
11 * defs.h: Add definition of null_cleanup()
13 * procfs.c: Many small changes to add base support for a new
14 "info proc" command (currently only printing of the address
15 space mapping is implemented) and allow iteration over the
16 address space mapping, calling an arbitrary function for each
17 mapping (used for shared library support).
19 * solib.c: Change all ifdefs that checked for "sun" to check
20 for "!SVR4_SHARED_LIBS" instead. Rewrite lookup_base() to
21 handle locating the debug base address even when not currently
22 stopped at the dynamic linker entry point.
24 * utils.c: Add null_cleanup() as a known function that does
25 nothing to serve as a base for possibly long cleanup chains
26 with no specific "first cleanup" to serve as an anchor.
28 * xm-sysv4.h: Add define of SVR4_SHARED_LIBS
30 Fri Dec 27 10:11:33 1991 Per Bothner (bothner at cygnus.com)
32 * arm-opcode.h, m88k-opcode.h, pn-opcode.h, np1-opcode.h,
33 pyr-opcode.h, tahoe-opcode, vax-opcode.h: Removed -
34 these are all essentially the same as the versions
35 in ../include/opcode. The remaining *-opcode.h here
36 are not quite so obviously the same, and need study.
37 * arm-pinsn.c, gould-pinsn.c, m88k-pinsn.c, pyr-pinsn.c,
38 tahoe-pinsn.c, vax-pinsn.c: Change so these include
39 opcode/FOO.h (actually ../include/opcode/FOO.h)
40 instead of the recenntly departed opcode-FOO.h files.
41 * sparc-pinsn.c: Now that we're using the much tighter
42 opcode table in ../include/opcode/sparc.h, we shouldn't
43 need to sort the opcodes before dis-assembly.
45 * symtab.h, symmisc.c: Make cplus_struct_default be const.
46 * symtab.h, buildsym.c: Add and use INIT_CPLUS_SPECIFIC macro.
47 * symmisc.c: Remove unused 'nfields' variable.
48 * buildsym.h: Add extern decl of unknown_symtype_complaint,
49 since it used used by partial-stab.h (included two places).
50 * partial-stab.h: Re-arrange DBXREAD_ONLY #ifdefs so that
51 we should never hit the default case (until new stab codes
52 are added). Hence, we can leave the complaint in the
53 default case in even when DBXREAD_ONLY is off.
54 * partial_stab.h: Recognize a pair of N_SO stabs (one for the
55 directory, one for the filename proper) without peeking ahead.
56 * dbxread.c, mipsread.c: Because of previous change, don't need
57 ugly CHECK_SECOND_N_SO macro.
58 * buildsym.h, dbxread.c, mipsread.c: Make next_symbol_text a
59 macro that invokes a function pointer in next_symbol_text_func.
60 * mipsread.c: Added comments various places to
61 explain what is going on.
62 * mipsread.c (parse_symbol): Support the new (SGI-specific?)
63 symbol types stStruct, stUnion, and stEnum.
64 Also, some fixes in the code for dealing with tags.
65 * mipsread.c: Change handling of startup_file_start and _end
66 - now just use the textlow and texhigh of a psymtab
67 to check if we've found the startup-file.
68 * mipsread.c: Replace s_idx by global cur_sdx in many places.
69 This is so mips_next_symbol_text can get at it.
71 Thu Dec 26 19:52:01 1991 Fred Fish (fnf at cygnus.com)
73 * dbxread.c, symmisc.c: Move add_psymbol_to_plist() from
74 dbxread.c to symmisc and change name to add_psymbol_to_list.
75 Ditto for add_psymbol_addr_to_plist(). Also expand their
76 body to not use ADD_PSYMBOL_VT_TO_LIST.
78 * dwarfread.c: Remove add_psymbol_to_list() and convert usages
79 to the ADD_PSYMBOL_TO_LIST macro.
81 * ieee-float.c: Change "#ifdef DEBUG" to "#ifdef IEEE_DEBUG"
82 to avoid collision with the DEBUG for ADD_PSYMBOL_VT_TO_LIST.
84 * partial-stab.h, symfile.h: Move definitions of the macros
85 ADD_PSYMBOL_TO_LIST and ADD_PSYMBOL_ADDR_TO_LIST from
86 partial-stab.h to symfile.h. They aren't stab specific.
87 Change ADD_PSYMBOL_VT_TO_LIST to use memcpy rather than strncpy.
89 Tue Dec 24 11:38:08 1991 John Gilmore (gnu at cygnus.com)
91 * Makefile.in: Roll VERSION to 4.3.2.
93 Mon Dec 23 13:54:35 1991 Per Bothner (bothner at cygnus.com)
95 * m68k-opcode.h, mips-opcode.h, sparc-opcode.h: Deleted.
96 * m68k-pinsn.c, mips-pinsn.c, sparc-pinsn.c:
97 Include <opcode/FOO.h> instead of <FOO-opcode.h>.
99 * symtab.h, symtab.c, coffread.c, dwarfread.c, symmisc.c,
100 dbxread.c: The TYPE_CPLUS_SPECIFIC structure is now only
101 allocated when it is needed. Until it is needed, it points
102 to a shared statically allocated structure.
104 * buildsym.h, buildsym.c, dbxread.c: Remove the kludgy code
105 in read_ofile_symtab to recognize two initial N_SO stabs,
106 and let process_on_symbol handle it. This is cleaner, more
107 efficient, and lets mipsread.c share the same code.
109 * symfile.h, partial-stab.h: Move ADD_PSYMBOL_VT_TO_LIST
110 and related macros to here ...
111 * dbxread.c: ... from here.
112 * symmisc.c: Move the "overflow" handling from
113 ADD_PSYMBOL_VT_TO_LIST macro into new function extend_psymbol_list.
114 * dwarfread.c: Re-write add_psymbol_to_list to use
115 ADD_PSYMBOL_VT_TO_LIST macro.
117 * mipsread.c: Extend mipsread.c to handle stabs-style symbols
118 encapsulated in ecoff symbols. This enable full g++ debugging.
119 * partial-stab.h: Move the code for pre-scanning symbols
120 and building psymtabs to an include file, out from dbxread.c.
121 This way, the same code can also be used by mipsread.c.
122 * dbxread.c, buildsym.h: Various changes to allow some functions
123 to be used by mipsread.c (also some arguable stylistic changes).
125 * tm-mips.h: Define BLOCK_ADDRESS_ABSOLUTE, at least for now,
126 since mips-tfile puts relocatable addresses into LBRAC/RBRAC
129 * mipsread.c: Replace code to handle ambiguous tag blocks.
130 Instead of allocating a TYPE_CODE_UNDEF, guess (by looking
131 at types and offsets) if a tag is a struct, union, or enum.
132 Still patch it later if we find out for sure.
133 * mipsread.c: In various ways, replace Forin's
134 ideo-syncratic code by code that fits better with the
135 rest of gdb, for both stabs-based and ecoff-based symtabs.
136 E.g. use end_psymtab; don't do extra passes over FDR table to
137 pre-partition global data; don't use external symbols to
138 create static/global symbols (just put them in the
139 misc_vector); use ADD_PSYMBOL_TO_LIST macro; don't
140 sort psymtabs or symtabs; use obstacks more.
142 * symtab.c, mipsread.c, dbxread.c, buildsym.c:
143 ANSIfy: Replace bcopy by memcpy, bzero by memset.
145 Sun Dec 22 19:31:04 1991 Fred Fish (fnf at cygnus.com)
147 * solib.c (locate_base): Fix uninitialized variable that was
148 causing return of random value to callee.
150 * config/mh-amix, config/mh-i386v4: Change to find alloca by
151 compiling and linking alloca.c, even when it is not strictly
152 required. Also arrange to link with -ltermlib rather than
155 * Makefile.in: Move TERMCAP definition to prior to inclusion
156 of host makefile fragments so it can be overridden.
158 Fri Dec 20 16:33:39 1991 John Gilmore (gnu at cygnus.com)
160 * xcoffread.c (read_symbol_lineno): Logic error in incrementing
161 symbol table entry number. (From Metin Ozisik.)
163 Fri Dec 20 11:36:38 1991 Fred Fish (fnf at cygnus.com)
165 * config/mh-i386v4: Change XM_CLIBS to "-lc /usr/ucblib/libucb.a"
166 so compiles with native compilers (without builtin alloca) can
167 pick up the version from the bsd emulation library. However, we
168 search the standard C library first so we don't pick up lots of
169 other broken stuff from libucb.a, that we *don't* want.
171 * configure.in, tm-amix.h, tm-i386v4.h, xm-amix.h, xm-i386v4.h:
172 Change svr4 references to sysv4.
174 * source.c: Move declaration of external function index to
175 front of file so it is in scope for all references.
177 * utils.c (error, fatal): Make definitions consistent with
178 defs.h declarations (declared as "volatile void").
180 Fri Dec 20 10:55:36 1991 John Gilmore (gnu at cygnus.com)
182 * rs6k-opcode.h: Bugfix sfe and stbrx. By Al Kossow.
184 Wed Dec 18 17:09:06 1991 Stu Grossman (grossman at cygnus.com)
186 * command.h, defs.h, eval.h, expression.h, remote-sa.sparc.c,
187 sparc-tdep.c, symtab.h, target.h, value.h, vx-share/ptrace.h,
188 vx-share/xdr_ptrace.h, vx-share/xdr_rdb.h: ANSIfy enums.
190 Mon Dec 16 12:31:46 1991 Fred Fish (fnf at cygnus.com)
192 * config/mt-amix, config/mt-i386v4: Add solib.o to TDEPFILES
193 for these SVR4 systems.
195 * symfile.c (symbol_file_add): When verbose is set, print
196 the names of files from which symbols are being loaded, as
197 when from_tty is true.
199 * solib.c: Completely reorganized (rewritten) to support
200 SVR4 shared libraries in a manner very close to the original
201 SunOS implementation. This support is expected to change and
202 become more general at some future time. The SVR4 version
203 does not yet work for attached processes, for example.
205 * dwarfread.c: Arrange in dwarf_build_psymtabs() for the
206 relocation address to be valid whether or not symbols are
207 being read from a shared library or an executable. Use the
208 relocation address recorded in the psymtab when reading
209 full symbol tables (in read_ofile_symtab). Ensure that the
210 relocated address ranges are recorded in partial symtabs.
212 * elfread.c: Add new function elf_interpreter() to return the
213 string from the ELF ".interp" section. This is the interpreter
214 that the kernel tries to run and feed the executable to.
215 Expand arguments to record_misc_function to include a type arg.
216 Modify elf_symtab_read() to supply the type arg, and to do symbol
217 relocations for symbols read in from shared libraries.
219 * procfs.c: Add new functions proc_base_address() and
220 proc_address_to_fd(), used by shared library support.
222 * tm-svr4.h: Add macros to support SVR4 shared libraries.
223 Definitions for SOLIB_ADD, SOLIB_CREATE_INFERIOR_HOOK,
224 CLEAR_SOLIB, and DISABLE_UNSETTABLE_BREAK.
226 Fri Dec 13 20:11:26 1991 John Gilmore (gnu at cygnus.com)
228 * infrun.c, remote-eb.c, remote-nindy.c, remote-vx.c: Remove
229 unused START_INFERIOR_HOOK.
231 * remote-eb.c: Change timeout to 24 seconds (*10 fits in byte)
232 to account for slow loading from floppies.
233 (eb_create_inferior): New fn, from eb_start and
234 nindy_create_inferior.
235 (eb_close): Only use log_file if nonzero.
236 (eb_xfer_inferior_memory): If not writing, then read!
237 (eb_read_inferior_memory, eb_write_inferior_memory): Return length.
238 (eb_kill): A new no-op.
239 (eb_mourn_inferior): Remove breakpoints, then generically weep.
241 Fri Dec 13 16:09:23 1991 Fred Fish (fnf at cygnus.com)
243 * breakpoint.c, findvar.c, infrun.c, putenv.c, stack.c: Fix
244 miscellaneous comparisons of integer with NULL that elicit
245 compiler warnings about comparison of integer with pointer, when
246 NULL is ((void *) 0) rather than just a bare 0.
248 Wed Dec 11 13:02:58 1991 John Gilmore (gnu at cygnus.com)
250 * breakpoint.c (breakpoint_re_set_one): Disable each breakpoint
251 while we reset it, in case of problems. Print breakpoint number
254 * buildsym.c (read_struct_type): Avoid sun3 compiler bug with
257 * source.c (find_source_lines): If getting file mod time fails,
260 * target.c (target_xfer_memory): If errno is set, return it,
263 Tue Dec 10 04:07:22 1991 K. Richard Pixley (rich at rtl.cygnus.com)
265 * Makefile.in: infodir belongs in datadir.
267 Sun Dec 8 21:13:33 1991 Michael Tiemann (tiemann at sphagnum.cygnus.com)
269 * symtab.h (struct fn_field): Add new fields `is_private',
270 `is_protected', `is_stub', making room by reducing the size of
272 (struct fn_fieldlist): Delete the fields `private_fn_field_bits'
273 and `protected_fn_field_bits'.
274 (TYPE_FN_{PRIVATE,PROTECTED}_BITS): Deleted.
275 (SET_TYPE_FN_{PRIVATE,PROTECTED}): Deleted.
276 (TYPE_FN_{PRIVATE,PROTECTED}): Deleted.
277 (TYPE_FN_FIELD_{STUB,PRIVATE,PROTECTED}): New macros.
278 * valops.c, valprint.c, symtab.c: All callers updated.
280 * buildsym.c (read_struct_type): Delete the `visibility' field
281 from `struct next_fnfield', and rework code so that visibility
282 info is stored into the fn_field directly. Also, hacked to set
283 TYPE_FN_FIELD_STUB for both static and normal member functions.
285 Sat Dec 7 18:13:11 1991 Fred Fish (fnf at cygnus.com)
287 * i386-tdep.c: Fix a problem on i386 systems where buffered code
288 stream access was failing to take into account the minimum size
289 granularity of the code section. For now, the buffering is simply
290 disabled. There is a similar problem in the i386 disassember code
291 that has not yet been fixed (FIXME).
293 * gmalloc.c: Use macros to hide some of the ugly casting required
294 in the previously applied fix for pointers with high bits set.
296 Sat Dec 7 16:49:35 1991 John Gilmore (gnu at cygnus.com)
298 * Makefile.in: Roll VERSION to 4.3.1.
300 Sat Dec 7 04:12:35 1991 John Gilmore (gnu at cygnus.com)
304 * Makefile.in: Roll VERSION to 4.3
305 * README, TODO, WHATS.NEW, depend: Update.
307 * inflow.c (terminal_inferior): Avoid error msg if attached.
309 * gmalloc.c: Fix bug that causes malloc & free to
310 fail on systems where pointers have the high bit set (0x800efcf0
311 for example). The problem is that the difference between two
312 pointers is a signed integer, so the computation
314 (char *) 0x800efcf0 - (char *) 0
316 yields a negative value. The sign of the result of the modulus
317 operator is machine dependent for negative operands, thus it is
318 possible for it to end up negative. From Fred Fish.
320 Sat Dec 7 00:00:15 1991 K. Richard Pixley (rich at rtl.cygnus.com)
322 * Makefile.in: install using INSTALL_PROGRAM and INSTALL_DATA.
323 added clean-info. added some standards.text support and made it
324 look like our other Makefiles.
326 * configure.in: mark this directory target dependent. configure
327 now runs entirely in objdir so make existence tests and
328 references against ${srcdir}.
330 Fri Dec 6 08:30:36 1991 Fred Fish (fnf at cygnus.com)
332 * dwarfread.c (enum_type, struct_type): Fixes for opaque and
333 anonymous enumerations, structures, and unions. Now passes all
334 the current gdb test suite tests.
336 Thu Dec 5 22:46:13 1991 K. Richard Pixley (rich at rtl.cygnus.com)
338 * Makefile.in: idestdir and ddestdir go away. Added copyrights
339 and shift gpl to v2. Added ChangeLog if it didn't exist. docdir
340 and mandir now keyed off datadir by default.
342 Thu Dec 5 21:53:21 1991 John Gilmore (gnu at cygnus.com)
344 * symtab.c (decode_line_1): If SKIP_PROLOGUE leaves us in
345 mid-line, be more careful about possibly advancing to the next line.
347 Thu Dec 5 18:59:51 1991 Michael Tiemann (tiemann at cygnus.com)
349 * cplus-dem.c (cplus_demangle): Call `string_need' when
350 null-terminating a partially-computed string.
352 Thu Dec 5 18:19:43 1991 Fred Fish (fnf at cygnus.com)
354 * dwarfread.c (enum_type): Build a correct TYPE_NAME, add a
355 symbol to the symbol table for each member of the enum.
357 * dwarfread.c (struct_type): Build a correct TYPE_NAME.
359 * dwarfread.c (add_enum_psymbol): New function to extract enum
360 member names and add them to the partial symbol table while
361 building partial symbol tables.
363 Thu Dec 5 17:31:05 1991 John Gilmore (gnu at cygnus.com)
365 * symtab.c (check_stub_method): Must allocate two extra argument
366 slots (one for `this', one for arglist terminator).
368 Thu Dec 5 10:51:05 1991 Fred Fish (fnf at cygnus.com)
370 * inflow.c (child_terminal_info): Supply missing '"' character.
372 * buildsym.c (define_symbol): Supply missing parenthesis.
374 Thu Dec 5 03:34:21 1991 John Gilmore (gnu at cygnus.com)
376 * coredep.c (fetch_core_registers): Fencepost error. Fixed by
377 Jay Lepreau <lepreau@cs.utah.edu>.
379 * inflow.c: Remember whether GDB has a terminal. Avoid switching
380 terminals back and forth if we don't have one.
382 * c-exp.y (parse_number): Zero is not an unsigned int constant!
383 * dbxread.c (read_dbx_symtab): Enum type numbers can be in (1,2) form.
385 Improve type parsing.
386 * buildsym.c (define_symbol, read_range_type): Add
387 long_kludge_name that passes the names of range types being
388 defined, down to where we must choose between 'int' and 'long'
389 variants. This fails on Sun C anyway since the compiler itself is
390 confused between int and long.
391 (read_array_type, cleanup_undefined_types): Correct the size of
392 array type whose element-type size isn't immediately known.
394 Early preparation to blow away many builtin types, building them
395 on the fly as needed. Don't compare types to builtin types with
396 ==; examine the relevant fields instead.
397 * coffread.c (process_coff_symbol: C_ARG, C_REGPARM): Avoid ==.
398 * buildsym.c (define_symbol, case 'p'): Avoid ==.
399 * valops.c (value_arg_coerce): Avoid ==. Don't assume host and
400 target types are the same.
401 * valprint.c (val_print): I finally understand arrays, remove FIXME.
403 * symmisc.c (printpsyms_command): Reduce redundancy, and put all
404 addresses in GDB itself into parens for easy cleanup and diffing.
406 Wed Dec 4 21:05:30 1991 Fred Fish (fnf at cygnus.com)
408 * dwarfread (enum_type): Arrange for the order of enumeration
409 members to match the source code order; not the order in the
410 Dwarf information, which is explicitly reverse order.
412 Wed Dec 4 18:24:39 1991 John Gilmore (gnu at cygnus.com)
414 * main.c (input_from_terminal_p): Check whether GDB has a
416 (initialize_main): Revise doc for `set editing'.
418 Wed Dec 4 15:36:39 1991 Fred Fish (fnf at cygnus.com)
420 * dwarfread.c (struct_type): Handle structures and unions which
421 contain DIE's other than just member dies.
423 Wed Dec 4 01:59:05 1991 John Gilmore (gnu at cygnus.com)
425 * symfile.c (reread_symbols): Avoid kludging mtime_set, now that
428 Tue Dec 3 17:24:57 1991 John Gilmore (gnu at cygnus.com)
430 * Makefile.in: VERSION 4.2.96.
432 * main.c (initialize_main): Revise command descriptions.
433 * command.c (show_user): `info user' -> `show user'.
434 * symtab.c (_initialize_symtab): Typo in `info types' desc.
436 * coffread.c (coff_symfile_read): Avoid select_source_symtab,
437 since it is not needed and can cause errors when examining ".o"s.
438 (read_coff_symtab, decode_base_type): Use complain, not printf.
439 Print symbol name, not its number.
440 Remove "#if defined(clipper) #define BELIEVE_PCC_PROMOTION", which
441 someday should go in a clipper target config file.
443 * symfile.c (compact_misc_function_vector): Handle empty vector.
444 (complain, clear_complaints, syms_from_objfile): Fix complaint
446 * xcoffexec.c: Change syms_from_objfile caller.
448 * sparc-xdep.c: Force tm-file as tm-sparc.h, to make it compile
449 when configured for cross debugging. FIXME, this needs a more
452 Mon Dec 2 11:04:05 1991 Per Bothner (bothner at cygnus.com)
454 * mips-tdep.c (init_extra_frame_info): Float register
455 'i' has gdb-internal number 'FP0+i', not '32+i'.
456 * mipsread.c (new_symbol): Translate g++ special
457 symbol "$t" to "this".
459 Sat Nov 30 21:29:55 1991 Steve Chamberlain (sac at cygnus.com)
460 Changes due to include file renaming:
462 * xcoffread.c: internalcoff.h ->coff/internal.c,
463 coff-rs6000.h ->coff/rs6000.h
464 * mipsread.c: coff-mips.h ->coff/mips.h
465 * elfread.c: elf-common.h ->elf/common.h

469 * dbxread.c: aout64.h ->aout/aout64.h
470 stab.gnu.h ->aout/stab_gnu.h
472 * coffread.c: internalcoff.h ->coff/internal.h
473 * buildsym.c: stab.gnu.h ->aout/stab_gnu.h
474 * depend Updated to take the above into account.
476 Fri Nov 29 16:59:25 1991 Fred Fish (fnf at cygnus.com)
478 * configure.in: Add SVR4 i386 configurations.
480 * config/mh-i386v4, config/mt-i386v4, tm-i386v4.h, xm-i386v4.h:
481 New files for i386/SVR4.
483 * tm-i386v.h: Allow START_INFERIOR_TRAPS_EXPECTED and
484 DECR_PC_AFTER_BREAK to be predefined by files including
487 * i386-tdep.c: Add supply_gregset(), fill_gregset(),
488 supply_fpregset(), and fill_fpregset() functions, which are
489 target dependent support functions for the SVR4 /proc register
492 * dwarfread.c (enum_type, struct_type): Expand recognized
493 compiler generated tags to include symbols beginning with '.' as
496 * symtab.c (sources_info): Change simple printf of error message
499 Fri Nov 29 16:04:21 1991 Roland H. Pesch (pesch at cygnus.com)
501 * doc/gdb.texinfo: remove leading comments that survived M4 but
502 described its role in the doc; add one more font to colophon;
503 strengthen disclaimer about unsupported configs.
505 Wed Nov 27 01:23:41 1991 John Gilmore (gnu at cygnus.com)
507 Fix bugs in C++ debugging.
509 * symtab.h: target_type is not used in record types.
510 Eliminate TYPE_MAIN_VARIANT and TYPE_NEXT_VARIANT. Eliminate
511 lookup_method_type. Add TYPE_TYPE_SPECIFIC macro.
513 * symtab.c (lookup_member_type): Don't chain them up, just
514 allocate one in symbol_obstack when we need one.
515 (allocate_stub_method): Build stub in symbol_obstack.
516 (check_stub_method): Move here from values.c. Don't deallocate
518 (lookup_method_type): Gone now.
520 * buildsym.c: Handle g++ v1 stabs a little bit better.
521 Change some C++ parsing error()s to complain()ts.
522 * buildsym.c, findvar.c, printcmd.c, symtab.c: Make unions and
523 structs have the same representation and work the same as far as
525 * buildsym.c, symtab.c, values.c: Remove all references to
526 TYPE_MAIN_VARIANT and TYPE_NEXT_VARIANT.
528 * valops.c: Improve comments and indentation. Only call
529 check_stub_method when the stub flag is on.
530 * valprint.c: Fix or mark minor bugs and unportabilities.
532 * coffread.c (anonymous unions): Allocate a cplus structure.
534 * mipsread.c: Eliminate "template" types. Build new, real
535 types whenever we need them. Allocate cplus structures as needed.
536 Bulletproof the type parsing a bit more. Mark storage leaks.
537 (parse_type): Copy TYPE_TYPE_SPECIFIC when copying a real type
538 on top of a partial type.
540 Fri Nov 22 16:39:57 1991 John Gilmore (gnu at cygnus.com)
542 * inflow.c (terminal_inferior): Check the results of ioctl's, and
543 print a message if any of them fail.
544 (terminal_ours_1): Store result of ioctl's for debugging, but
545 don't print (the terminal isn't ours...).
547 * tm-tahoe.h (FRAME_ARGS_ADDRESS): No need to offset from frame
550 * m2-exp.y (MAX, MIN): Rename to MAX_FUNC, MIN_FUNC to avoid
551 conflicts with system header files.
553 Fri Nov 22 08:27:40 1991 John Gilmore (gnu at cygnus.com)
555 * Roll VERSION to 4.2.95.
557 * buildsym.c, coredep.c, mem-break.c, xcoffread.c: Put <stdio.h>
558 first, before defs.h.
559 * config/mh-i386sco: Override compiler to gcc, print warning.
560 * configure.in: Handle i386-none-aout rather than i386-aout-none.
561 * infptrace.c, language.h, utils.c: Lint.
562 * m2-exp.y: #undef MAX and MIN in case system includes set them.
563 * xm-tahoe.h: Set HOST_BYTE_ORDER. Include system versions of
564 {BIG,LITTLE}_ENDIAN and the INT_MAX family first, to avoid
565 redefinition warnings.
566 * defs.h: Reorder things so that the xm-file gets first crack
567 at #define's, followed by defs.h and then the tm-file.
568 * Makefile.in: Remove spaces after 'ignore exit code' - flags.
569 Late-model BSD 'make's don't cope with them.
571 Thu Nov 21 23:48:56 1991 John Gilmore (gnu at cygnus.com)
573 * Makefile.in: Roll new files into various lists.
575 Thu Nov 21 18:26:11 1991 Fred Fish (fnf at cygnus.com)
577 * dwarfread.c (struct_type): Must initialize the c++ specific
578 portion of union types as well as struct types, since gdb attempts
579 to reference the c++ specific info for both types.
581 Thu Nov 21 10:23:52 1991 John Gilmore (gnu at cygnus.com)
583 * Makefile.in: Roll VERSION to 4.2.90.
585 * defs.h: Incorporate param.h into defs.h. All users changed.

594 * Makefile.in: Remove getpagesize.h, param.h, param-no-tm.h.
596 * exec.c (exec_files_info): If `verbose' is set, show file offset

601 * xm-*.h: Remove fake values of MAXPATHLEN.
603 * xcoffexec.c: Add /* */ to #if 0'd thing to help ANSI.
605 Wed Nov 20 18:35:56 1991 John Gilmore (gnu at cygnus.com)
607 * Remove gdb/hp-include. Support for HP a.out oddities should be
608 in BFD, not in GDB. Move gdb/hp-include/a.out.h to include/a.out.hp.h.
610 * infptrace.c, tm-sun386.h: Cashier <a.out.gnu.h>, remove refs.
612 * configure.in, xconfig, tconfig, Makefile.in, doc/gdbint.texinfo:
613 Makefile fragments for various hosts and targets now come from
614 gdb/config/mh-* and gdb/config/mt-*. This is for consistency with
617 * rs6000-pinsn.c, rs6k-opcode.h: Clean up.
618 * rs6k-opcode.def: Delete.
620 Wed Nov 20 05:04:40 1991 Fred Fish (fnf at cygnus.com)
622 * dwarfread.c: Recognize obsolete form of AT_element_list
623 attribute still used by at least one AT&T compiler, and possibly
626 Tue Nov 19 07:53:55 1991 Fred Fish (fnf at cygnus.com)
628 * dwarfread.c (enum_type, struct_type): Ignore names invented by
629 helpful compilers for anonymous structs, unions, and enums.
631 * c-exp.y, m2-exp.y: Add defines for yymaxdepth, yy_yys, and
632 yy_yyv, so multiple parsers produced by SVR4 versions of yacc
633 can coexist in the same executable without collision.
635 * symtab.h: Add declaration for lookup_template_type() to kill
636 compiler warnings about conversions from int to pointer.
638 Mon Nov 18 17:45:18 1991 Fred Fish (fnf at cygnus.com)
640 * procfs.c: Move inclusion of defs.h to before param.h, as in
641 all the other source files that include both. This is required
642 to supply some typedefs that are used in files included by param.h.
644 * m68k-tdep.c (m68k_skip_prologue): Add generic m68k support for
645 skipping function prologues, ala the other cpu families (i386,
646 mips, m88k, etc). Add the ability to skip movm and fmovm
647 instructions in the prologues. Still needs support for profile
648 (-p compiled) prologue sequences (FIXME).
650 * tm-68k.h: Change SKIP_PROLOGUE macro to use the new generic
651 m68k prologue skipping function by default.
653 * tm-altos.h, tm-isi.h: Continue to use the old definition of
656 Mon Nov 18 15:12:45 1991 John Gilmore (gnu at cygnus.com)
658 * Makefile.in: Remove tdesc stuff, and extra blanks before colons.
659 * blockframe.c: Remove tdesc-related code. Default
661 * infrun.c: Remove tdesc-related code.
662 * m88k-tdep.c (frame_chain_combine, init_frame_pc): Remove copies
663 of defaultable things.
664 * tm-m88k.h: New file, common to all Moto 88k target configs.
665 Derived from tm-delta88.h.
666 * tm-delta88.h: Use it.
667 * xm-m88k.h: Common file for 88K hosts. Remove obsolete stuff.
668 * xm-delta88.h: Use it.
669 * tm-*.h: Remove FRAME_CHAIN_COMBINE macros, since all are
671 * coffread.c: Remove tdesc stuff.
672 * tconfig/delta88, tconfig/m88k: Remove tdesc stuff.
673 * xconfig/m88k: Rename tm-88k.h to tm-m88k.h.
675 Mon Nov 18 13:51:37 1991 Per Bothner (bothner at cygnus.com)
677 * source.c (open_source_file): If openp fails, try again
678 using just the base (non-directory) part of the filename.
679 This solves various annoying problems, such as when the
680 source was compiled with an absolute pathname - and the
681 source files have moved. Or if the source was compiled
682 using a relative pathname, it can be more convenient
683 to just specific the source directory to the dir command.
685 Mon Nov 18 00:04:41 1991 Fred Fish (fnf at cygnus.com)
687 * cplus-dem.c (munge_function_name): Add missing third arg to
688 instance of call to do_type().
690 * dwarfread.c: Changes to match new dwarf.h. Remove
691 AT_deriv_list, AT_loclist, AT_incomplete, AT_const_data,
694 Sun Nov 17 16:20:53 1991 Michael Tiemann (tiemann at rtl.cygnus.com)
696 * symtab.h (struct type): Moved C++-specific fields into new type
697 `struct cplus_struct_type'. Now takes 10% less memory. Many
699 * symtab.c (init_type): Don't set fields belonging to
700 TYPE_CPLUS_SPECIFIC unless TYPE is TYPE_CODE_STRUCT.
701 * buildsym.c (read_type): Allocate TYPE_CPLUS_SPECIFIC for
703 (read_struct_type): Ditto. Also, add comments about how we can
704 deduce TYPE_VPTR_FIELDNO from inheritance info and fieldname info.
705 * coffread.c (decode_base_type): Allocate TYPE_CPLUS_SPECIFIC for
707 (read_struct_type): Ditto.
708 * dwarfread.c (struct_type): Ditto.

721 * mipsread.c (parse_partial_symbols): patch to keep DEC C
722 compiler from making gdb bomb out. Thanks to Ed Santiago!
724 Thu Nov 14 19:27:30 1991 Fred Fish (fnf at cygnus.com)
726 * symfile.c: Add function compact_misc_function_vector() to
727 remove duplicate misc function vector entries. See comments
728 in source for why this is necessary/desirable.
730 * dwarfread.c: Add misc function type parameter to internal
731 record_misc_function(). Remove calls to init_misc_bunches()
732 and condense_misc_bunches(), these are now done in elfread.c.
734 * elfread.c: Add support for reading bfd canonical symbol tables
735 and generating misc function vector entries for global and
736 absolute symbols. Do calls to init_misc_bunches() and
737 condense_misc_bunches() where they will enclose all calls to
738 record_misc_function(), including those in dwarfread.c.
740 Thu Nov 14 17:02:11 1991 Roland H. Pesch (pesch at cygnus.com)
742 * doc/Makefile.in: new targets gdb.me, gdb.ms, gdb.mm
743 (roffable documentation).
744 * doc/gdb.texinfo: embedded hints (as comments) for better
745 texi2roff conversion.
747 Thu Nov 14 13:18:25 1991 John Gilmore (gnu at cygnus.com)

761 Motorola 88000 port without tears, I mean without tdescs.
763 * m88k-tdep.c: Blow away all tdesc stuff.
764 Provide functions for all the frame-related macros in
765 tm-delta88.h. Adopt i960-style EXTRA_FRAME_INFO.
766 (examine_prologue, frame_find_saved_regs, skip_prologue): borrow
767 from i960-tdep.c and adapt to the function prologues on the 88k.
768 (read_next_frame_reg): Borrow from mips-tdep.c.
769 FIXME: frame_locals_address should go away.
771 * tm-delta88.h: Dump all the tdesc stuff.
772 Macros for all frame-related stuff call fns of same name.
773 Remove duplicated definitions. FP_REGNUM becomes same as
776 * xm-88k.h: Eliminate lots of library dependencies, now handled
777 in libiberty. Eliminate KDB nonsupport.
779 * doc/gdbint.texinfo: Add rudiments on frames. FIXME, add more.
782 * stack.c (frame_info): Mark frameless functions.
783 Print locals address (FIXME, remove if same).

800 Allow setting breakpoints on C++ destructors.
801 * valops.c (destructor_name_p): Don't check TYPE_HAS_DESTRUCTOR,
802 since it lies. Rely on callers to catch missing destructors.
803 * symtab.c (decode_line_1): For example (see above), here.
804 * buildsym.c, symtab.h: Remove TYPE_FLAGS_HAS{CON,DE}STRUCTOR
805 flags since they are no longer used.
807 Fixes to support C++ methods with functional parameters.
808 * c-exp.y (func_mod rule): Allow (and ignore) list of parameter
809 types in a function type.
810 * eval.c (parse_and_eval_type), value.h: New function,
811 parse_and_eval_type, is based on old code from check_stub_method.
812 But don't actually evaluate the cast, since that calls
813 value_cast(), whcih may fail. Just extract the type
814 from the parsed expression.
815 * values.c (check_stub_method): While looping through the
816 arguments, adjust depth *after* parameter has been handled.
817 Replace call and setup of parse_and_eval with new function
820 Tue Nov 12 09:40:07 1991 Fred Fish (fnf at cygnus.com)
822 * utils.c, rem-multi.shar: Remove fixed arg count version of

827 m88k-xdep.c, main.c, printcmd.c, pyr-xdep.c, source.c,
828 sun386-xdep.c, symm-xdep.c, umax-xdep.c, values.c, xcoffread.c:
829 Change all instances of use of fixed args concat() to variable
830 args concat() now located in libiberty.
832 Tue Nov 12 07:23:46 1991 John Gilmore (gnu at cygnus.com)

837 * buildsym.c: Add hooks for xcoffread.c.
838 * rs6000-pinsn.c, rs6000-tdep.c, rs6000-xdep.c, tm-rs6000.h,
839 xm-rs6000.h, rs6k-opcode.def, rs6k-opcode.h: New files.
840 * xcoffexec.c: New file for handling AIX shared libraries.
842 Mon Nov 11 19:14:31 1991 Fred Fish (fnf at cygnus.com)
844 * core.c: Minor rewording of message to user containing name of
845 (and possibly arguments to) the program that generated a core

856 * dwarfread.c (dwarf_psymtab_to_symtab): Remove leftover call
857 to do_cleanups() which resulted from a previous change.
859 * elfread.c: Re-enable compilation of register_addr() stub
860 whenever it is not supplied by coredep.c
862 Sat Nov 9 00:40:32 1991 John Gilmore (gnu at cygnus.com)
864 Add tracking of object files (that contain symbols) to gdb.
865 This includes a "struct objfile" that owns symtabs and psymtabs
866 that were read in from that binary file.
868 * symfile.h: Add struct objfile. Add pointer to the objfile
869 into the struct sym_fns.
870 Replace global `symfile' and `symfile_mtime' with
871 `symfile_objfile'. Add global object_files chain.
873 * symfile.c: Move param.h above symtab.h.
874 (sort_misc_function_vector): Add.
875 (syms_from_objfile): Was syms_from_bfd.
876 (symfile_open): Now returns objfile.
877 (allocate_objfile): New.
878 (free_objfile): New, replacing free_all_.*symtabs.

900 (dbx_alloc_type): Check file number, not sym number, for -1.
901 (find_symbol_in_list): Add for xcoffread.
902 (start_symtab): Default typevector is empty. Keep reusing same
904 (end_symtab): Take objfile argument and pass it to
905 allocate_symtab. Don't make a symtab if no blocks or symbols.

930 (struct symtab): Add objfile * and objfile_chain * of symtabs.
931 (struct partial_symtab): Add objfile * and objfile_chain * of
932 psymtabs. Remove symfile_name.

941 * symfile.h, symfile.c, symtab.h: Lint
943 Fri Nov 8 23:38:48 1991 John Gilmore (gnu at cygnus.com)
945 * command.c: Include param.h.
946 * defs.h (warning_setup, warning): Declare.

952 Thu Nov 7 18:26:15 1991 Steve Chamberlain (sac at rtl.cygnus.com)
954 * Makefile.in: link with libiberty after libreadline, since
955 readline might want something in libiberty.
956 * m88k-xdep.c: Fixed the register offsets in the ptrace_user
957 struct for BCS 88k machines.
958 * xm-m88k.h: don't define USIZE if already defined.
959 * configure.in: Added delta88 target.
961 Thu Nov 7 04:51:19 1991 John Gilmore (gnu at cygnus.com)
963 * am29k-pinsn.c, am29k-opcode.h: Fix decoding of mtacc, dmac, fmac.
965 * tm-*.h: Remove READ_DBX_FORMAT, COFF_FORMAT, and
966 READ_MIPS_FORMAT, which have been unused since BFD. Still
967 remaining is COFF_NO_LONG_FILE_NAMES.
968 * tm-sun3.h, tm-altos.h: Remove detritus accidentally left from
969 function calling code moved to m68k-tdep.c.
971 Wed Nov 6 17:21:59 1991 John Gilmore (gnu at cygnus.com)
973 * coffread.c: Eliminate c_nsyms in favor of c_naux.
974 Complain if no auxents on .bf and .ef FCN symbols, and assume
975 lots of line numbers.
976 (init_linenos, enter_linenos): Use a sentinel at the end of the
977 read-in linenos, to make for a fast, safe loop-end test.
979 Wed Nov 6 02:54:08 1991 Steve Chamberlain (sac at cygnus.com)
981 * coffread.c (read_coff_symtab): coffread used to rely on the
982 x_sym.x_misc.x_lnsz.x_lnno field giving the # of linnos in a
983 function. Two of the formats I'm using (29k and 88k) don't seem to
984 set it. Ths patch to fcn_last_line and (enter_linenos) is an
985 attempt to use the actual size of the linno table in the file to set
986 the number of linenos to process.
988 Tue Nov 5 22:47:46 1991 Steve Chamberlain (sac at cygnus.com)
990 * Makefile.in: put a - infront of the mv y.tab.c c-exp.tab.c and
991 mv y.tab.c m2-exp.tab.c, so that if bison is used, and the files
992 are created in place, so the mv fails, then the make continues.
994 Tue Nov 5 16:47:47 1991 Per Bothner (bothner at cygnus.com)
996 Add C++ as a separate language.
997 * defs.h (enum language): Add language_cplus.
998 * dwarfread.c (end_symtab): Support language_cplus.
999 * c-exp.y: Add new struct language_defn cplus_language_defn.
1000 Don't set c to be the default language (see main.c).
1001 * c-exp.y (yylex): Only look for field of this if
1002 language is C++. (First difference from C!)
1003 * language.c: Add case branches for C++ (currently, all
1004 the same as C). Also, add c++ to "usage" note for "set lang".
1005 * valprint.c (typedef_print). Add case branches for C++.
1006 * main.c (main): New way to set initial language: Look at
1007 file extension of psymtab containing main(). (Same as we
1008 do for symtabs, but avoid loading the symtab yet.)
1009 * symtab.c: New routine find_main_psymtab(), used by main()
1010 to set initial language.
1011 * symfile.c (allocate_symtab): Move code for mapping file
1012 extensions-> languages to new deduce_language_from_filename().
1014 Fix a C++ problem when looking for methods in super-classes.
1015 There was confusion between base and derived types.
1016 * valops.c (value_fn_field): Change function interface.
1017 * values.c: Use new value_fn_field interface.
1019 Mon Nov 4 10:49:33 1991 Per Bothner (bothner at cygnus.com)
1021 * infrun.c: Fixed typo in comment.
1022 * utils.c: All the v*fprintf emulation is now in libiberty,
1023 so we can get rid of some junk.
1024 * xm-sun3os4.h, xm-sun4os4.h, xconfig/decstation, xconfig/i386sco,
1025 xconfig/sun3os4, xconfig/sun4os4: Don`t need HAVE_STRSTR any more.
1026 * m68k-pinsn.c (print_insn_arg): Support BB/BW/BL
1027 type operands, as used by branch instructions.
1028 * gmalloc.c: Fix prototype of memcpy.
1029 * elfread.c: Comment out register_addr, since it conflicts
1030 with the one in coredep.c.
1031 * buildsym.h: Remove extern declarations of two functions
1032 that are really static in buildsym.c.
1033 * tm-mips.h: Add symbolic names for more registers.
1034 * mips-xdep.c (store_inferior_registers): Use new register names.
1035 * xm-mips.h: Simplify REGISTER_U_ADDR, since it is now
1036 only used for core files, not ptrace. Therefore,
1037 the KERNEL_U_ADDR hack is no longer needed.
1038 The mapping to ptrace number is now in in mips-xdep.c.
1039 * mips-xdep.c: Define REGISTER_PTRACE_ADDR (using the
1040 mapping from the old REGISTER_U_ADDR), and use it
1041 in {fetch,store}_inferior_registers.
1042 * mipsread.c: Rename #include ecoff.h to new name coff-mips.h.
1043 * mips-tdep.c (mips_push_dummy_frame, mips_pop_frame):
1044 Save/restore FP regs correctly (?).
1045 * dbxread.c: Remove duplicate define_symbol and type_synonym_name
1046 (these had been previously moved to buildsym.c).
1047 Hence, define_symbol becomes extern instead of static.
1048 * buildsym.c (read_struct_type): Comment out bogus handling
1049 of C++ operator methods. Minor hacking of reading of class
1050 contexts. Make define_symbol non-static, so dbxread.c can call it.
1052 Fri Nov 1 11:05:47 1991 John Gilmore (gnu at cygnus.com)
1054 * mipsread.c (read_mips_symtab, read_the_mips_symtab): Use real
1055 filename with error messages.
1056 * stack.c (frame_select_command): Rename to select_frame_command
1057 to avoid "fr" and "fra" having nonunique completions.
1058 * symfile.c (sort_symtab_syms): Ignore sort of zero symtab *.
1059 (symfile_init): Print file format name when unable to handle it.
1060 (free_named_symtabs): Use BLOCKVECTOR rather than obsolete BLOCKLIST.
1061 * symmisc.c (free_symtab): Only free linetable if nonzero.
1062 * symtab.h: Remove obsolete BLOCKLIST macros.
1064 Thu Oct 31 18:12:43 1991 Stu Grossman (grossman at cygnus.com)
1066 * infrun.c (wait_for_inferior): another stepi/nexti fix. Ensure
1067 that stop_step is 1 at bottom of main loop. I don't know why this
1068 needs to be done, but it helps me sleep better at night.
1070 Sun Oct 27 18:18:39 1991 Stu Grossman (grossman at cygnus.com)
1072 * main.c (initialize_history): Read history after reading all
1075 Sun Oct 27 14:09:25 1991 John Gilmore (gnu at cygnus.com)
1077 * buildsym.c: Break out initial malloc sizes.
1078 (record_line): Record directly in a subfile. Alloc on demand.
1079 (compare_line_numbers): Add from xcoffread.c.
1080 (end_symtab): New params say whether to sort pendings and
1081 linetable. Patch block stabs if defined. Shrink linetable before
1082 allocating the symtab.
1083 * buildsym.h: Delete line_vector* and prev_line_number. Add
1084 global_stabs and file_stabs for xcoffread.
1085 * dbxread.c (start_subfile): Move to buildsym. Change above calls.
1086 * symtab.h: LINETABLE(symtab) can now be null. Zap LINELIST.
1087 * symmisc.c, symtab.c: Cope with null LINETABLEs.
1089 * blockframe.c: Pass fromleaf to INIT_EXTRA_FRAME_INFO.
1090 * tm-29k.h, tm-88k.h, tm-i960.h, tm-irix3.h, tm-mips.h, tm-pyr.h,
1091 tm-sparc.h: Accept fromleaf parameter.
1092 * c-exp.y (yyerror): Pass error message if given.
1093 * configure.in: Add rs6000 host and target.
1094 * inflow.c (new_tty): O_NOCTTY kludge for RS/6000.
1095 * symfile.h (entry_point): Add.
1097 Sat Oct 26 00:16:32 1991 John Gilmore (gnu at cygus.com)
1099 * buildsym.c: New file. Breaks out symbol-table-building routines
1100 from dbxread.c, so they can be shared with xcoffread.c.
1101 * buildsym.h: New file. Declarations for buildsym.c users.
1102 * dbxread.c: Remove large chunks into buildsym.c.
1103 * Makefile.in: Add buildsym.c and buildsym.h.
1105 * symfile.c (syms_from_bfd): New routine.
1106 (add_symbol_file): Call it to do the real work.
1107 (syms_from_bfd): Initialize entry_point before calling symfile_init.
1108 * symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
1109 Avoid declaring or setting entry_point (symfile.h & symfile.c cope).
1111 Fri Oct 25 10:58:16 1991 Mark Eichin (eichin at cygnus.com)
1113 * cplus-dem.c (cplus-demangle): added support for templates, static
1114 data, and the new (correct) mangling for destructors.
1116 * dwarfread.c: (dwarfwarn): created a varargs version of
1117 dwarfwarn, for non __STDC__ compilers.
1119 * c-exp.y: (yylex): added match for "template" token.
1120 (typebase): added TEMPLATE name '<' type '>' clause, for explicit
1121 specification of template types.
1123 * symtab.c: (lookup_template_type): new function for finding
1124 templates in symbol table.
1125 (type_name_no_tag): changed to explicitly check for s/u/e at the
1126 beginning of the symbol - if it is a template, none of these will
1127 be there (but the name will still contain spaces.)
1129 Fri Oct 25 18:59:32 1991 Per Bothner (bothner at cygnus.com)
1131 Various fixes to improve g++ debugging.
1132 * symtab.h: Add is_const and is_volatile flags for each method.
1133 These are bit fields - take their space from voffset,
1134 which shrinks to 30 bits. Since voffset is now a bitfield,
1135 make it unsigned for portability. This changes its interpretation
1136 slightly: Static methods now have voffset 1 instead of -1,
1137 and virtual offsets start at 2, not 1.
1138 * symtab.c: Renamed gdb_mangle_typename to gdb_mangle_name,
1139 since it now returns an entire magled method name, not just
1140 the type part. This avoids some duplication.
1141 It also allows us to correctly mangle const and volatile
1142 methods (using the new is_const and is_volatile bit fields
1144 * valprint.c (type_print_base), values.c (check_stub_method):
1145 Simplify by using new gdb_mangle_name.
1146 * values.c (value_headof): Fix to correctly handle single
1147 inheritance (actually two fixes, either of which suffices).
1148 * dbxread.c (read_struct_type): Handle const and volatile
1150 * dbxread.c (read_struct_type): Yet one more place where
1151 we must handle '\\' continuations.
1152 * valprint.c (vtbl_ptr_name): Add final '\0'.
1154 Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com)
1156 * tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of
1157 short return values for sparc and 68k. Patch from Paul Eggert.
1159 * coffread.c, coredep.c, i386-xdep.c: install patches for
1160 SysV/386 3.2 from Mauro DePalma.
1162 Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
1164 * core.c (core_file_info), exec.c (exec_file_info): Print file
1165 type. Use printf_filtered.
1167 * valops.c (value_fetch_lazy): Avoid 0-length fetches.
1169 Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
1171 * dwarfread.c: Add casts to remove compiler warnings.
1173 * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
1174 tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
1175 tm-sun3.h: Remove locally duplicated code for calling functions
1176 in the inferior. The only differences were in the specific trap
1177 vectors used and whether or not an fpu was present. These are
1178 now handled by appropriate definitions of BPT_VECTOR and
1179 HAVE_68881 respectively. Other minor obvious cleanups.
1181 * valops.c: Correct a minor misspelling.
1183 * utils.c: Remove local BSD/USG hacks that are now in libiberty.
1185 * dwarfread.c: Remove prototype for dwarfwarn. Does not work
1188 Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
1190 * stack.c (frame_command): Always print. Use new
1191 frame_select_command to select a frame without printing.
1193 * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
1195 Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
1197 * dwarfread.c: New file for DWARF debugging format support.
1199 * elfread.c: New file for ELF object file format support.
1201 * procfs.c: New file for SVR4 /proc (process file system) support.
1203 * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
1206 * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
1208 * xm-m68k.h: New file for host machines with m68k cpu.
1210 * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
1211 Add elfread.o and dwarfread.o to OBS.
1213 * symfile.h: Add "elf" to list of supported formats in comment.
1215 * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
1216 types to gdb, builtin_type_long_double, builtin_type_complex, and
1217 builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
1218 TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
1219 TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
1220 TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
1221 types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
1223 * infrun.c: When using SVR4 /proc interface instead of ptrace(),
1224 call proc_set_exec_trap() to setup child to stop at first instruction.
1226 * inftarg.c: When using SVR4 /proc interface, call proc_wait()
1229 * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
1230 supply_fpregset(), and fill_fpregset(), which are machine
1231 dependent support routines for SVR4 /proc interface.
1233 * utils.c: Add warning_setup() and warning(). Warning() behaves
1234 the same as error() except that it returns normally rather than
1235 jumping back to command level. Modules that don't want to call
1236 warning() for some reason, but want to produce their own warnings,
1237 can call warning_setup() to ensure compatibility with the way
1238 warning() and error() deal with the terminal.
1240 * symtab.c: Make internal errors produce more useful messages.
1242 * tm-68k.h: Move code that is duplicated in almost every single
1243 m68k based machine's configuration files to this common file.
1244 Duplications in the configuration files still need to be removed
1247 * infrun.c (child_create_inferior): System V versions must call
1248 setpgrp() with no arguments, to comply with prototyping typically
1251 * munch: Add support for SVR4 style nm output.
1253 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
1254 file specific fields from the partial symbol table structure and
1255 replace them with a pointer to private data for each different
1256 flavor of object file reader to initialize appropriately.
1258 Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
1260 * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
1263 * mipsread.c (fixup_undef_type): New function. If a struct /
1264 union / enum is defined in a header file but nowhere else used,
1265 (by typedefing, pointer referencing or declaration) the mipsread code
1266 builds the complete tree for the structure but leaves its code as
1267 TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
1268 Guess its type based on the details of the members.
1270 Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
1272 * infrun.c (wait_for_inferior): Check return value from
1275 Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
1277 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
1278 by my last edit to this routine.
1280 Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
1282 * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
1283 FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
1284 the values before putting them into the dummy code. (From Peter
1287 Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
1289 * configure.in: added ebmon target.
1291 Wed Oct 16 22:49:58 1991 John Gilmore (gnu at cygnus.com)
1295 * Makefile.in: Roll VERSION to 4.2.
1296 * README, TODO, WHATS.NEW: Update.
1298 * core.c (core_open): Improve error message for bad file.
1299 Pass .reg virtual memory address to fetch_core_registers to help
1300 it find the registers in the core-file header.
1301 * coredep.c (fetch_core_registers): Take new argument, use it,
1302 and pass it to register_addr to locate the block of registers.
1303 * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
1305 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
1306 Sequent N_FN_SEQ like everybody else's N_FN.
1308 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
1309 * tm-i386v.h: #endif guck.
1310 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
1311 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
1312 * xconfig/tahoe: Add REGEX, which seems to be missing.
1314 * coredep.c: Add <sys/types.h> for SCOnix.
1315 * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file.
1316 * printcmd.c (print_formatted): Flush output before disassembly.
1318 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1320 * doc/refcard.tex (sec "Working Files"): consistent metavars and
1321 other improvements, due to comments by François Pinard
1322 (pinard@iro.umontreal.ca)
1324 * doc/gdb.texinfo (appendix "Installing GDB"): changes in
1325 configure, and improvenets related to Pinard's refcard comments
1327 Tue Oct 15 08:45:12 1991 John Gilmore (gnu at cygnus.com)
1329 Changes from Fred Fish:
1330 * tm-68k.h (FPI_REGNUM): Add.
1331 * infrun.c (child_create_inferior): flush stdout and stderr
1333 * configure.in: Handle amigados, amix hosts and targets.
1334 * inflow.c: Handle TIOCGLTC_BROKEN for Amiga.
1336 From Andreas Schwab:
1337 * values.c (show_convenience): Use printf_filtered.
1338 * main.c (define_command): Check result of lookup_command for
1340 (echo_command): Use printf_filtered, and force output out.
1342 * dbxread.c (read_enum_type): Avoid Modula-2 kludge that breaks C
1344 * i387-tdep.c (double_to_i387): Fix typo for double_to_ieee_extended.
1345 * utils.c (_initialize_utils): If !ISATTY, don't paginate.
1346 * configure.in, tconfig/decstation, xconfig/decstation: Rename
1347 dec3100 to decstation.
1349 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)
1351 * doc/gdb.texinfo: Catch up to changes recorded here in ChangeLog
1352 (nodes Continuing and Stepping; Memory; Targets) clarifications
1355 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
1357 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move
1358 REGISTER_U_ADDR to corresponding xm- file. Sugg. by Peter Schauer.
1360 * symmisc.c (print_partial_symtabs): Add printpsyms debug cmd.
1362 * m68k-tdep.c (m68k_push_dummy_frame, m68k_pop_frame): Add
1363 generic routines for calling inferior functions.
1365 * blockframe.c (inside_main_scope, inside_entry_scope): New.
1367 * copying.awk: Filter formfeeds out of copying & warrantee.
1368 Make them available as `show copying' and `show warrantee' also.
1369 * main.c (print_gnu_advertisement): Advt `show' commands.
1371 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)
1373 * mach386-xdep.c: Even when cross-compiling, leave in the
1374 core-file reading code.
1375 * core.c (get_core_registers): Avoid coredump if no .reg section.
1377 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
1379 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
1380 This avoids coredumps under `set print object on' in value_headof
1381 (called erroneously by value_from_vtable_info) for `p &struct'
1382 or `p *struct'. From Peter Schauer.
1384 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
1386 * Makefile.in: Roll version to 4.1.2.
1387 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
1388 size from BFD (but, FIXME, we don't yet read external nlists's and
1389 convert them to internal nlists's before handling them -- we still
1390 assume they have the same size and alignment.) Use SET_NAMESTRING
1392 * exec.c (exec_file_command): Move dead coff-encapsulation code
1394 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.
1396 Fri Oct 4 22:30:06 1991 John Gilmore (gnu at cygnus.com)
1398 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
1399 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
1401 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
1403 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
1404 * mips-xdep.c (store_inferior_registers): Don't try to
1405 write the (pseudo) FP.
1406 * mipsread.c (parse_partial_symbols): Improved algorithm for
1407 setting pst->texthigh.
1409 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
1411 * doc/Makefile: make TEXINPUTS include . everywhere
1413 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
1415 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
1416 vestiges of typevectors, which were for symsegs and are no longer
1417 used. (From a question by Eliot Dresselhaus
1418 <dresselh@RFT30.nas.nasa.gov>).
1420 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
1422 * dbxread.c, coffread.c: static-ize functions that were
1423 gratuitiously external. (From Fred Fish.)
1425 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
1427 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
1428 until it is large enough.
1430 * dbxread.c (read_type): Handle error case slightly better.
1431 Make complaint message not C++-specific.
1433 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
1435 * infrun.c (wait_for_inferior): Fix step/next so that you only
1436 stop at the beginning of a new line. This fixes various problems
1437 with for loops, nested if-else's and switch statements.
1439 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
1441 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
1442 between symtabs and psymtabs become ordinary error()s.
1444 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
1445 properly, making "end pc" correct in shared lib psymtabs.
1446 (From Guy Harris <guy@auspex.com>.)
1448 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
1450 * dbxread.c: Enable, but soften, const_vol_complaint.
1451 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
1452 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
1453 should be file-scope, not global.
1454 (read_struct_type): Remove ancient multiple-inheritance warning.
1455 (read_range_type): Check base type, complain & patch if undefined.
1456 * stack.c (frame_info): Demangle the function name in `info stack'.
1457 (From Peter Schauer)
1459 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
1461 * eval.c (evaluate_subexp_for_address): Don't use
1462 TYPE_POINTER_TYPE directly (it might be zero if this type has
1463 never had a pointer created before); use lookup_pointer_type.
1464 * symtab.c (lookup_method_type): Arguments were swapped in all
1465 callers, so fix it here. I'm amazed this worked at all!
1467 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
1469 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
1470 "bss" rather than "data" symbols, but which still conflict.
1473 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
1474 * core.c (core_files_info): Shorten output.
1475 * exec.c (exec_files_info): Ditto.
1476 (build_section_table): Ignore zero-length sections.
1477 * language.c, printcmd.c: Lint.
1478 * language.h (get_frame_language): Declare.
1479 * saber.suppress: update.
1480 * stack.c (find_relative_frame): Remove complex code that was
1481 #if 0'd, stick with simple code. Lint.
1482 * saber.suppress: Update a bit.
1483 * symfile.c (add_symbol_file_command): Add "?" to question.
1484 * utils.c (parse_escape): Avoid \a due to bdead compilers.
1485 * value.h: Declare typedef_print.
1487 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
1490 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
1491 (Reported by Mark Peek <mark@imagen.com>.)
1493 * solib.c (solib_map_sections): Relocate all sections, even
1494 though only the text section's size is tracked. Mark ld_text
1495 for eventual elimination as we generalize to N sections.
1497 * infrun.c (wait_for_inferior): Don't check if the PC is in a
1498 call_dummy if we were stopped by a random signal that is being
1499 passed to the program. This produced wierd results when calling
1500 functions in the inferior and signals (e.g. SIGALRM) were in use.
1502 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
1504 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
1505 Bugfix from Paul Eggert <eggert@twinsun.com>.
1506 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
1507 * valprint.c (print_floating): Print 9 digits for IEEE floats.
1510 Mon Sep 23 15:50:07 1991 John Gilmore (gnu at cygnus.com)
1512 * Makefile.in: Roll VERSION to 4.1.1.

1516 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
1520 * Makefile.in (VERSION): Set to 4.1.
1521 * language.c (set_language_command): Print useful help message,
1522 and restore the language string after giving help.
1523 * valprint.c (typedef_print): Print typedef in C or M2.
1524 * symtab.c (list_symbols): Use it.
1525 * main.c (main): Avoid any output before (gdb) prompt when -q.
1526 * language.c (set_language_command): Handle errors by restoring
1527 the language string to its current state (fix from A. Beers).
1528 * doc/gdbint.texinfo: Roll in information from README. Rearrange
1529 "how to install" and "how to print the doc" stuff so it drops
1531 * configure.in: Rename rtpc CPU to romp to match config.sub.
1532 * README, WHATS.NEW, TODO: Update for gdb-4.1.
1534 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
1536 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
1537 autoloading shared libs, copyright etc on GDB startup, clean up $_
1538 and $__ index refs, set/show listsize and related updates to list
1539 cmd. New host/target configs.
1541 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
1543 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
1544 from main Makefile.in version definition
1545 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
1547 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
1549 * doc/gdb.texinfo: merge new language-switching and lang-specific
1552 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
1554 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
1555 compilers (which may lack stddef.h).
1557 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
1559 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
1560 N_WARNING are the same except for the N_EXT bit, so just use their
1561 values alone, rather than OR-ing them with N_EXT.
1563 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
1565 * mipsread.c (parse_lines): Deal with negative extended line
1568 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
1569 global symbol conflicts.
1571 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
1573 * .gdbinit: Move 'set complaints' to top, so it runs even in
1574 case we aren't debugging GDB.
1575 * language.c (_initialize_language): Fix type check and range
1576 check documentation strings.
1577 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
1578 language.c can use it. (Though language.c should really not be
1579 handling warnings/errors the way it does, FIXME.)
1580 * symtab.c (lookup_primitive_type): const lint.
1582 Bugfix from Peter Schauer:
1583 * source.c (lines_to_list): Make signed, to avoid comparison
1584 going unsigned and complaining that -3 is too high for 21 lines.
1585 * stack.c (lines_to_list): Ditto.
1587 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
1589 * Makefile.in (HFILES): Add minimon.h.
1590 (VERSION): Roll version number to 4.0.95.
1591 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
1592 New rules for building distributions. Normal distribution
1593 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
1594 one level up from here; it calls make-proto-gdb.dir to build a
1595 directory `proto-gdb' which is an image of the release. The old
1596 `gdb.tar.Z' rule still works too.
1597 * config.sub, configure: Roll in latest from ..
1599 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
1601 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
1602 new-target, and new-config chapters; fix minor typos; come closer
1603 to usual GNU markup conventions for @file @samp @code @var.
1605 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
1607 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
1608 * mipsread.c (parse_partial_symbols): Enter the name of all
1609 structs/unions... into the psymtab so we can access them if the
1610 symtab is not read in.
1611 * mips-tdep.c: Remove some unneeded #includes.
1612 * xconfig/dec3100: Add HAVE_STRSTR.
1614 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
1616 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
1617 * c-exp.y, m2-exp.y: Lint.
1618 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
1619 * valprint.c (val_print_fields): Check for stub type.
1620 * mipsread.c (_initialize_mipsread): Avoid using
1621 builtin_type_void at initialize time.
1622 (mipscoff_symfile_read): use it now.
1624 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
1626 Merge multiple-language support, and partial Modula-2 support,
1627 from Andrew Beers <beers@cs.buffalo.edu>.
1629 * i387-tdep.c: New file, consolidates most 80387 support,
1630 and eliminates host dependency on double<->extended conversions.
1631 * i386-xdep.c, symm-xdep.c: Remove most 387 support.

1638 * mipsread.c (new_symtab): Use it. Minor formatting changes.
1639 * dbxread.c (end_symtab): Use it.

1649 (process_coff_symbol): #if 0'd for functions and params as above.
1650 (read_enum_type): Recognize Modula-2 BOOLEAN.
1651 * symtab.c (add_param_to_type): #if 0'd function to add a

1655 * i386-xdep.c, pyr-tdep.c, pyr-xdep.c, remote-vx.c, solib.c,
1656 source.c, symfile.c, dbxread.c, breakpoint.c, core.c, exec.c,
1657 i387-tdep.c, infcmd.c, mips-tdep.c, stack.c, printcmd.c: Output
1658 hex with local_hex_string for Modula-2 support.
1660 * breakpoint.c (breakpoint_cond_eval): Use new value_true to test
1661 breakpoint condition language-independently.
1663 * parse.c: New file with the common code remains of expread.y.
1664 * parser-defs.h: New file with common declarations from expread.y.

1687 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1689 * expression.h (enum exp_opcode): Add Modula-2 specific opcodes.
1690 * expprint.c: Look up expression opcodes in language-specific

1723 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
1725 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
1726 entries are enclosed herein. Not all of these changes
1727 have been merged into the master GDB sources -- check the
1728 ChangeLog above here for the merge log.
1730 Mon Jun 3 17:05:45 EDT 1991
1732 m2-exp.y Created. Tested outside of GDB for a few days. Proper
1733 operators were added, C specific operators and tokens
1734 removed. yylex() revamped to some extent. Still things
1735 missing from the grammar, such as sets.
1736 Tested for two weeks in GDB v3.5.
1738 Tue Jun 11 17:23:48 EDT 1991
1740 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
1741 so they are built-in. Sort of a hack.
1743 Fri Jun 14 12:53:51 EDT 1991
1745 m2-exp.y Added range checking for numeric constants. Any numeric
1746 constant is assumed to be of builtin type INTEGER unless:
1747 (1) it is octal or hexadecimal, in which case it is a
1748 CARDINAL; (2) it is too big to fit into an INTEGER, in
1749 which case it is a CARDINAL.
1750 eval.c Added simple range checking for +, -, and * on integers.
1751 Doesn't work very well for *, since 6 * 1,000,000,000 =
1752 1,705,032,704, which fails the simple test of result >=
1753 first_operand, no matter in what order the operands are.
1755 Tue Jun 18 14:11:30 EDT 1991
1757 Broke the parser into parts, one containing the C grammar and the other
1758 containing code to be shared by all of the grammars.
1760 The following files no longer exist:
1765 The following files were added:
1767 c-exp.y (The C grammar)
1768 m2-exp.y (The Modula-2 grammar)
1769 parser-code.c (Code that is shared by the above grammar)
1773 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
1774 now necessary to use the Bison compiler compiler, since it
1775 will generate function/variable prefixes other than yy.
1777 Tue Jun 18 16:47:49 EDT 1991
1779 symtab.[ch] Added the external variable working_lang, than holds the
1780 value of the current working language.
1781 Added the ennumerated type language_mode, with the values
1782 language_auto and language_manual, the former meaning that
1783 GDB sets working_lang as needed, and the latter meaning
1784 that the value of working_lang is totally under user
1786 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
1787 REAL, BOOLEAN and CHAR. Also added the type codes
1788 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1789 utils.c Added set_language_command and show_language_command to
1790 implement the GDB support commands "set language" and
1792 expression.h A number of identifiers were added to the type exp_opcode
1793 to facilitate Modula-2 builtin functions, integer
1794 division, and array indexing.
1796 Wed Jun 19 13:25:58 EDT 1991
1798 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
1799 if the language specified by working_lang requires the use
1800 of strict typing of expressions. Eventually, even this
1801 will be able to be changed by the user.
1802 Added the macro RANGE_CHECK, which evaluates to non-zero
1803 if the language specified by working_lang requires the
1804 checking of a value against the domain of its type.
1805 Eventually, even this will be able to be changed by the
1807 language.[ch] Predicates involving types (simple_type, ordered_type,
1808 same_type, integral_type, numeric_type, character_type,
1809 boolean_type, float_type) are added. These predicates are
1810 based on the current value of working_lang, and are handy
1813 Wed Jun 19 15:39:34 EDT 1991
1815 eval.c Added the function type_array_rank which computes the rank
1817 valarith.c Added the funtion value_bool, which when given a integer
1818 value.h value (ie. struct value *) as an argument, it returns a
1819 boolean value (ie. struct value *) true if that integer
1820 is non-zero, and a boolean value false otherwise.
1821 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
1822 will print out properly.
1824 Wed Jun 19 16:36:34 EDT 1991
1826 valops.c Added the function value_capitalize, which returns it
1827 value.h argument capitalized if its argument is a lowercase
1828 letter, or the argument unchanged if its argument is not a
1830 valarith.c Added the function range_check_p, which returns non-zero
1831 value.h if its value argument is between the integral bounds upper
1833 Added the function range_check_enum_p, which makes sure
1834 that its value argument is a valid member of the domain of
1836 Added the function range_check_range_p, which makes sure
1837 its value argument lies between the upper and lower bounds
1838 of its type argument, which must be a ranged type.
1839 Added the function check_array_index, which range and type
1840 checks an index of an array.
1841 Added the function value_multi_subscript, which computes
1842 array[idx1,idx2...idxN], given a value array and an array
1843 of values representing indicies.
1844 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
1845 unpack_long to work with TYPE_CODE_BOOL and
1848 Wed Jun 19 18:04:08 EDT 1991
1850 symtab.c Stored pervasive types in a structure and make
1851 lookup_pervasive_type() a lookup function that was based
1852 on working_lang. If lookup_pervasive_type() returned
1853 non-zero, then that value was returned (a fix, since
1854 before it simply wouldn't return the pervasive type.)
1855 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
1856 non-zero if the language specified by working_lang means
1857 "conversion" when it says "cast".
1858 valops.c Added the function value_real_cast(), which performs a
1859 value.h *cast*, not a *conversion*, which is what value_cast()
1860 does when it can. In particular,
1861 value_cast(<float_type>,4) = 4.0, while
1862 value_real_cast(<float_type>,4) = some mess.
1863 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
1864 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
1865 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
1866 and MIN on integral types. *NOTE*: These are currently
1867 hardcoded to work only if there are 8 bits per storage
1869 eval.c Made logical functions call value_bool to return a
1870 properly typed boolean value, based on working_lang.
1872 Thu Jun 20 11:55:27 EDT 1991
1874 valprint.c Types now print out in a Modula-2 fashion. This works for
1875 the cases when the type is printed out step-by-step, that
1876 is, it doesn't work when the name of a structured type
1877 (which includes the keyword "struct", etc.) is simply
1879 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
1880 since type specifications in C and Modula-2 are very
1881 different. The C printing of a type is very recursive,
1882 whereas in Modula-2 it is generally very simple. C has
1883 type prefixes and suffixes, which have no real analogue in
1884 Modula-2. Maybe type_print() should call a language
1885 specific type printer. This is also advantageous if we
1886 compile GDB to exclude some of the languages. We'll just
1887 leave those functions out.
1889 Thu Jun 20 16:57:10 EDT 1991
1891 dbxread.c When reading the complete symbol table in (via
1892 psymtab_to_symtab()), the number and types of function
1893 arguments are added to a function type. define_symbol()
1894 calls add_param_to_type() to accomplish this.
1895 Assumption: when we come across a function definition
1896 (N_FUN symbol with an 'f' or 'F' in the name), its
1897 arguments will appear before another function definition.
1898 When a function is found, a pointer to its type is placed
1899 in the global in_function_type. Changes that
1900 add_param_to_type() makes are to this global.
1901 valprint.c The type of a function now includes (for Modula-2) the
1902 types of its parameters.
1903 eval.c Type checking and a check for the proper number of
1904 arguments is now done for function calls. Not sure of the
1905 impact this has on C++ member function yet.
1907 Thu Jun 20 19:58:48 EDT 1991
1909 valprint.c Rewrote the type printer. Broke it into two language
1910 specific parts, adding the functions type_print_m2() and
1912 An unfortunate consequence is this: if you debugging a C
1913 program in Modula-2 mode (why?), info types does not work
1914 well with regular expressions, since the types are printed
1915 out in Modula-2 terminology, but stored in C terminology.
1916 language.[ch] Added the functions new_type_last(), type_keyword(), and
1917 type_sep() to aid in the printing of typedefs.
1918 symtab.c Made the printing of typedefs as language independent as
1919 possible through calls to new_type_last(), type_keyword(),
1922 Fri Jun 21 11:50:26 EDT 1991
1924 dbxread.c Check all incoming ennumerated types. If it looks like
1925 Modula-2's BOOLEAN type, then change the type_code of the
1926 type to TYPE_CODE_BOOL so we can process it as a boolean
1928 valprint.c Replaced some of the 0x%x with calls to sprintf and
1929 hexformat() in val_print().
1930 language.[ch] Added the function hex_to_string(), which converts its
1931 integral argument to a hexadecimal number (format is
1932 language based) and returns the result as a string.
1934 Mon Jun 24 12:25:07 EDT 1991
1936 valprint.c Some functions call type_print_1() directly, instead of
1937 value.h using type_print(), so they can specify where (column) to
1938 print things. Since type_print() takes care of language
1939 dependence, that needs to be called first. Added a
1940 parameter depth to type_print() (so it is now like
1941 type_print_1). Changed type_print to type_print_at, and
1942 made type_print a macro that passes a depth argument of
1944 symmisc.c Changed all calls to type_print_1 to calls to
1946 Makefile.dist Made it possible to build GDB for a specific set of
1947 depend languages. Do this by passing a definition for the macro
1948 LANGS to make. LANGS should be a string containing a
1949 space-separated list of language names (ie. LANGS="c m2").
1950 The default is to build all languages. Note that grammar
1951 files must follow the naming convention of <lang>-exp.y.
1952 gdb.lang This holds the current value of the LANGS macro. It is
1953 examined every time make is called, and is updated if
1955 eval.c Added #ifdef _LANG_<lang> to these files.
1956 expread.c Still need to add them to dbxread.c and coffread.c.
1964 Mon Jun 24 16:33:11 EDT 1991
1966 language.[ch] Added the functions hexformat_pre() and
1967 hex_to_string_pre(), which take a prefix argument to
1968 include in the format string. Thus, hexformat_pre("08") will
1969 return "0x08x" (if the working language is language_c).
1970 Made hexformat() and hex_to_string() calls to the above
1971 with "" as the prefix argument.
1973 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
1974 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
1975 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
1976 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
1977 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
1978 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
1979 valprint.c, vax-pinsn.c
1981 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
1982 calls to hexformat() and hex_to_string(). Format strings without
1983 the leading "0x" were ignored.
1985 depend Updated to take the above into account.
1988 Tue Jun 25 15:27:18 EDT 1991
1990 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
1991 and type_check_t to keep track of the current state of
1992 range and type checking.
1993 main.c Added the variables range_mode, range_check, type_mode,
1994 and type_check to record the current state of range and
1995 type checking. Added initialization code to main().
1996 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
1997 the above variables.
2000 Tue Jun 25 17:57:08 EDT 1991
2002 dbxread.c process_one_symbol() updates the variable (enum language)
2003 source_lang based on the extension of the filename
2004 contained in the N_SO sybmol that started this symtab.
2005 When end_symtab() is called, the value of source_lang is
2006 put into the language field.
2007 stack.c select_frame() sets working_lang (and possibly type_check
2008 and range_check) to the language field of the symtab
2009 associated with the frame that is selected if working_mode
2010 is language_auto. If working_mode is language_manual, a
2011 warning is printed and working_lang is not set.
2012 language.c Added the function set_type_range(), which sets the value of
2013 type_check and range_check (if their modes call for
2014 automatic setting) based on the current value of
2015 working_lang. A non-zero argument will cause the current
2016 settings to be output.
2019 Wed Jun 26 14:51:40 EDT 1991
2021 eval.c Added range checks on assignment.
2022 m2-exp.y Added the grammar for sets to the language. Currently,
2023 these do not do anything except print an error message.
2025 Wed Jun 26 17:01:04 EDT 1991
2027 m2-exp.y Added the ability for parse_number() to parse negative
2028 numbers. A global flag is set upon encountering a unary
2029 minus. This was done to make, for example, 1 parse as a
2030 CARDINAL, and not as an integer, per Wirth's examples in
2031 Programming in Modula-2 ed.4.
2032 valprint.c Added support for "set radix 2" by then setting
2033 output_format to 't'.
2034 eval.c Implemented range checking on subrange types. Added calls
2035 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
2036 Implemented MIN and MAX for ennumerated types. The
2037 minimum value of an ennumerated type is defined by Wirth
2038 as the first identifier, and the maximum as the last.
2039 m2-exp.y Made octal numbers ending with "B" be characters and those
2040 ending with "C" be numbers, per Wirth's book. (p. 34)
2042 Thu Jun 27 14:11:52 EDT 1991
2044 stack.c select_frame() now only sets working_lang, it does not
2045 notify the user. If working_mode is language_manual, then
2046 a warning is issued once.
2047 main.c At the end of each call to execute_command(), working_lang
2048 is checked against the local static (enum language)
2049 current. If they differ and working_mode is
2050 language_auto, the new settings of language, type and
2051 range checking are printed out.
2052 stack.c Modified frame_info() to include the language of the
2053 current frame in the output of "info frame".
2054 language.[ch] Added the function language_str() which returns the name
2055 of the current language.
2057 Fri Jun 28 15:33:14 EDT 1991
2059 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
2060 the language. INCL and DECL currently cause an error,
2061 since sets are not implemented yet. INC and DEC are
2062 implemented as PREINCREMENT/PREDECREMENT with one
2063 argument, and as ASSIGN_MODIFY with two arguments.
2064 eval.c Added type checking to the above cases.
2065 value.h Added not_lval_constant to the lval_type ennumerated type.
2066 not_lval_constant means that the value is a constant
2067 value; that is 3 or 'a' or TRUE, not as in a constant
2068 identifier. This is used to help coerce numbers such as 3
2069 to either signed or unsigned numbers.
2070 valops.c Added the function value_coerce_constants() which coerces
2071 constant integers as following: if one is a constant and
2072 the other is not, the constant's type is set to the type
2073 of the other argument. If both are constants and one is
2074 signed, the other is converted to a signed constant.
2076 Sat Jun 29 17:26:29 EDT 1991
2078 valarith.c Added a better range checker. It now checks range
2079 (successfully) on integral operations [+-] (signed and
2080 unsigned) for any C sized type. Still does not work well
2081 for multiplication.)
2082 int_in_size() returns an integer that is coerced to fit into
2083 specified number of bytes.
2085 Mon Jul 1 13:04:14 EDT 1991
2087 language.[ch] Added the function binop_result_type(), which returns the
2088 builtin (struct type *) type that would be the result of a
2089 binop on the two values V1 and V2.
2091 Wed Jul 3 19:22:53 EDT 1991
2093 source.c Extended source_info() to include the source language in
2094 the output from "info source".
2096 Fri Jul 5 13:48:52 EDT 1991
2098 utils.c Moved the support functions for the GDB set/show commands
2099 dealing with language into language.c.
2100 language.c Added the function language_info(), which displays info
2101 about the current working language, type and range check
2102 settings. Called via the GDB command "info language".
2103 Added an initialization routine _initialize_language(),
2104 that sets defaults for the language, type and range
2105 variables and sets up the new GDB commands.
2106 main.c Language setup moved to language.c.
2109 Mon Jul 8 10:10:22 EDT 1991
2111 valarith.c Debugged the range checker for arithmetic. Still does not
2112 work for multiplication very well.
2114 Mon Jul 8 12:40:37 EDT 1991
2116 language.[ch] Added the function value_true() which returns non-zero if
2117 its argument represents a boolean true value.
2118 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
2119 check the truth of an expression.
2121 Thu Jul 11 12:51:34 EDT 1991
2123 language.[ch] Added the predicate structured_type(), which returns
2124 non-zero if the argument is a structured type.
2125 Added the predicate pointer_type(), which returns non-zero
2126 if the argument is a pointer type.
2127 eval.c Added the ability to do addition and substraction on
2128 pointers and integers. This case simply bypasses the
2131 Thu Jul 11 14:41:42 EDT 1991
2134 Added the symbol N_DEFD (0x4a) which is a definition
2135 module dependency that is used by the GNU Modula-2
2136 compiler and the linker. It is not important to GDB,
2137 except that [dbx|coff|mips]read.c should ignore these
2140 Fri Jul 12 16:07:00 EDT 1991
2142 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
2143 0 in val_print(). Also added statements to the else part
2144 to coerce type (argument to val_print) to a pointer type
2145 if it is an "array of unspecified length".
2146 valops.c Added the function value_m2_string(), which returns a
2147 (value) value which is a constant string, whose type is
2148 (ARRAY [0..n] OF CHAR). The length field of the type
2149 structure is set to zero, so it will be interpreted as an
2150 "array of unspecified length".
2151 stack.c Moved the language/frame mismatch check to
2152 main.c:execute_command().
2153 main.c The working language is recorded each time
2154 execute_command() is executed. If working lang has
2155 changed during its execution, then the new
2156 language/type/range info is printed out for the user. If
2157 the working language does not match the language of the
2158 frame, a warning is issued.
2160 Sat Jul 13 16:16:39 EDT 1991
2162 eval.c Moved all the type-checking stuff for operators to
2163 language.[ch] language.c. This is so we can keep language-specific
2164 stuff (like for what type operators are defined) in
2166 language.[ch] Added the function binop_type_check(), which checks to see
2167 if its two (value) arguments are type-compatible with its
2168 opcode argument. The opcode should represent an operation
2169 involving an operator. Also added the macro function
2170 unop_type_check, which calls binop_type_check with a
2171 NULL second argument.
2172 expprint.c Added Modula-2 operators to the op_print_tab, so info
2173 expression.h break works correctly. Also added "op_string", which
2174 returns the string corresponding to the (enum exp_opcode)
2175 opcode that is its argument.
2178 Sat Jul 13 18:26:18 EDT 1991
2180 coffread.c Added code to record the type of function arguments with
2181 each paricular function. Code is very similar to that
2183 dbxread.c Moved add_param_to_type() to symtab.c
2184 symtab.[ch] Added function add_param_to_type() from dbxread.c
2186 *** NOTE: The above additions have not been tested.
2188 Mon Jul 15 12:50:47 EDT 1991
2190 langauge.[ch] Added the functions type_error and range_error, which work
2191 like error() except if the type/range mode is set to
2192 *_mode_warn, then they do not do a return_to_top_level(),
2193 but merely print a warning.
2194 Also changed [set|show]_[type|range]_command() to support
2195 the new "warn" feature.
2197 Thu Jul 18 17:50:54 EDT 1991
2199 mipsread.c Added code to record the type of function arguments with
2200 each particular function. Code is very similar to that
2203 *** NOTE: The above additions have not been tested.
2205 Fri Jul 19 11:19:10 EDT 1991
2207 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
2208 UMIN_OF_SIZE, which when given a size of a numeric type,
2209 return the maximum and minimum value it can hold. UMAX...
2210 and UMIN... return the result for unsigned types.
2211 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
2212 struct types. They call above macros.
2213 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
2214 avoid a name conlict with the above.
2215 c-exp.y Added range checking on numeric constants in
2216 parse_number() for completeness.
2217 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
2218 return 0 if working_lang is not language_c.
2220 Thu Aug 8 14:17:22 EDT 1991
2224 breakpoint.c Documentation strings of some commands changed to
2225 eliminate the references to the C language where
2228 Tue Aug 13 15:48:03 EDT 1991
2230 m2-exp.y Added qualified identifiers to the grammar. The semantics
2231 are slightly different from those of the GDB operator ::
2233 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
2234 type_exp, where type_exp is any valid type expression.
2236 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
2237 printcmd.c Modified ptype_command() so it actually parses the input
2238 (necessary for type expressions with scope qualifiers).
2239 Added the function ptype_eval() which expects an
2240 expression composed of one OP_TYPE element.
2241 *.[ch] Replaced all occurences of parse_c_expression with
2243 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
2245 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
2247 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
2249 Small fixes from Peter Schauer:
2251 * infrun.c (child_attach): Lint.
2252 * solib.c (find_solib): Handle shared libs version 2.
2254 Small fixes from David Wood:
2256 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
2260 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
2261 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
2263 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
2264 chars_per_line is at maximum (user typed `set width 0'). Fix
2265 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
2267 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
2269 * coredep.c: include ptrace.h where necessary.
2270 * mipsread.c(parse_lines): fix unsigned char problem that was
2271 messing up line numbers on SGI's and possibly other MIPS based
2273 * infrun.c (child_create_inferior): use better test to check
2274 return val from setpgrp().
2275 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
2276 for sgi/irix support.
2278 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
2280 * mipsread.c (parse_symbol): Put non-static procedures
2281 in the global block.
2283 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
2285 Patch together `text_start' and `text_end' for 29K port.
2287 * exec.c (exec_command): If NEED_TEXT_START_END, define the
2288 variables and set them based on the exec file.
2289 * am29k-tdep.c: declare text_start.
2290 * valops.c (call_function_by_hand): declare text_end.
2292 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
2293 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
2294 because machines that do this will also have to know to
2295 set NEED_TEXT_START_END. Besides, it was a redundant way to
2297 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
2298 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
2299 NEED_TEXT_START_END.
2301 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
2303 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
2305 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
2306 Pass MUNCH_DEFINE to munch whenever we run it.
2307 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
2308 format string; use 0x%x instead.
2309 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
2310 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
2311 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
2312 * inflow.c: Handle `short' process group IDs.
2313 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
2314 and check for ptrace errors.
2315 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
2316 (coff_symfile_init): Initialize text_bfd_scnum.
2317 (read_coff_symtab): Use it to find the text [and absolute?] sections.
2318 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
2319 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
2320 Merge target arm case with other "easy" cases. Add target
2321 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
2322 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
2324 * minimon.h, remote-adapt.c, remote-mm.c: Add.
2325 * munch: Cope with RT/PC putting fns in data segment.
2326 Restore ability to override `nm' by specifying MUNCH_NM.
2327 * xconfig/rtbsd, xconfig/ultra3: New host systems.
2328 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
2329 and remote-adapt. Remove encapsulated coff #define's (the
2330 support should go in BFD, and gdb shouldn't know or care).
2331 * tconfig/a29k-kern: Same, but for remote kernel debugging.
2332 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
2333 * tm-29k.h: Update BADMAG (though it should go away).
2334 Allow the register definitions to be overridden in another
2335 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
2336 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
2337 DUMMY_SAVE_GR96, for handling kernel calling conventions
2338 that use GR64+ rather than GR96+.
2339 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
2340 remote debugging of Ultra3 kernel. Includes tm-29k.h and
2341 overrides various things.
2343 * remote-mm.c (mm_attach, mm_wait): Handle attach like
2344 child_attach does, making a clean stop in the newly attached
2346 * remote-eb.c: Lint.
2348 * coffread.c: Make coffread independent of any particular
2349 variant of COFF. Avoid #include-ing any particular one except
2350 internalcoff.h. BFD now passes key values for symbol reading
2351 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
2352 and the symbol masks and shifts); use them.
2353 Remove obsolete end_of_text_addr.
2355 * exec.c: Remove unused include files.
2357 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
2359 * Makefile.in (documentation targets): Pass $(M4).
2360 Bugfix from eggert@twinsun.com (Paul Eggert).
2362 * stack.c (down_silently_command): Check for stack existence.
2364 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
2366 * Makefile.in (VERSION): Update to 4.0.3.
2368 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
2370 * core.c (core_file_command): Print frame at coredump with
2371 its level number, by calling print_stack_frame.
2372 * frame.h: Add selected_frame_level, print_stack_frame.
2373 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
2374 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
2375 Change print_sel_frame and print_selected_frame callers to
2378 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
2379 * symfile.c (free_named_symtabs): Ditto.
2380 * main.c (main): wrap_here needs an arg.
2381 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
2382 (solib_add): Avoid noise.
2383 (solib_create_inferior_hook): Lint.
2384 (sharedlibrary_command): Move dont_repeat to here.
2385 * utils.c (error): Call wrap_here to force buffered output.
2387 Small patches from Peter Schauer:
2389 * coffread.c (start_symtab): Free any existing line_vector before
2391 (read_coff_symtab): Ditto for type_vector.
2393 * source.c (lines_to_list): New variable, replacing function.
2394 (all uses): Use as variable.
2395 (_initialize_source): Add 'set listsize' and 'show listsize'.
2396 * utils.c (lines_to_list): Remove function.
2397 * stack.c (print_frame_info): Use as variable.
2398 * defs.h (lines_to_list): Remove declaration.
2400 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2402 * breakpoint.c (insert_breakpoints): Restore warning about
2403 the program might be running in another process, but only for
2404 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
2405 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
2407 * utils.c (error): if error_pre_print is set, print the string
2409 * main.c (main, print_gnu_advertisement, print_gdb_version):
2410 Reformat legalese so it always prints, but acts as an "I'm here"
2411 message while symbols are being read. If any errors occur,
2412 print a few newlines to set off the message and start it at the
2413 left margin. Remove mention of "help" command, and don't yak
2414 about symbol reading.
2415 (catch_errors): Error string is now printed first in case of
2417 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
2418 suggest the "help" command.
2420 * Makefile.in (VERSION): Set to 4.0.2.
2422 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
2424 * .gdbinit: Remove useless "rr" command. Set complaints
2425 to 1 for people debugging gdb.
2427 * breakpoint.c, remote-vx.c: Reword strings printed by
2428 catch_errors callers.
2430 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
2432 * WHATS.NEW: "history write -> history save". Doc "write on/off".
2433 (Fix from kenc@viewlogic.com.)
2435 Fix some infrastructure to be able to cope with host and target
2436 machines with different sized basic types (ints, ptrs, etc).
2437 (Idea from pierre@la.tce.com (Pierre Willard).)
2439 * values.c (value_from_longest): Rename from value_from_long.
2440 Handle pointer types as well as integers, so that targets with
2441 different pointer sizes from the host can be accomodated.
2442 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
2443 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
2444 uses of value_from_long to value_from_longest.
2445 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
2446 the correct pointer type to value_from_long{est}.
2448 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
2450 * remote-vx.c: Remove obsolete code for calling functions via
2451 vxworks kludge interface (it referenced value_from_long).
2453 * valops.c (value_string): Find malloc with lookup_misc_func, not
2456 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2458 Make writing to files work properly. (Fixes to BFD are also needed.)
2460 * core.c (core_open): Open file ourselves, read or r/w, depending on
2461 write_files. Use bfd_fdopenr.
2462 * gdbcore.h (write_files): New variable.
2463 * exec.c (write_files): Define variable, add set&show for it.
2464 (exec_file_command): Use write_files to open for read or r/write.
2466 Make shared library reading happen automatically. These changes
2467 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
2469 * inferior.h (stop_soon_quietly): Add to exported variables.
2470 * infrun.c (child_create_inferior): call solib hook, if defined.
2471 (child_attach): call solib hook, if defined.
2472 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
2473 (find_solib): Use lookup_misc_func rather than hand-rolled.
2474 (symbol_add_stub): New stub for catch_errors.
2475 (solib_add): Avoid output if !from_tty. Catch errors rather
2476 than just calling symbol_file_add and bombing.
2477 (solib_create_inferior_hook): Interface with the target process
2478 to let it read and alloc shared libs, then figure out what it did.
2480 * core.c (validate_files): Fix typo, soften warning.
2481 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
2483 * utils.c (fputs_demangled): Avoid duplicate printing if
2484 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
2486 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
2487 (Fix from pierre@la.tce.com (Pierre Willard).)
2489 * main.c (catch_errors): Change argument to a char * from an int,
2490 since a char * can point to a struct full of glop, but an int
2491 is not guaranteed to be able to hold a pointer.
2492 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
2493 breakpoint_re_set_one, breakpoint_re_set): Adapt.
2494 * core.c (core_open, solib_add_stub): Adapt.
2495 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
2497 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2499 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
2500 by adding .NOEXPORT target.
2502 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2506 * Makefile.in (VERSION): Roll to 4.0.
2507 (gdb.tar.Z): Make refcard.ps as well, for shipment.
2509 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2511 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
2514 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
2517 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
2519 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
2520 reflect above name change
2522 * WHATS.NEW: correct pointer to refcard.
2524 * doc/gdb.texinfo: update New Features, Installing
2526 * doc/gdbint.texinfo: add short description of configure +template
2528 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2530 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
2532 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
2534 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
2535 tar file, add dependencies for referenced doc files.
2537 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
2539 * coffread.c, symfile.c, stack.c: saberized.
2541 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2543 * doc/refcard.tex: permuted Essential Commands sec
2545 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
2547 set/show symbol-reloading
2548 default set complaints 0
2550 RET-repeat disabled after prompted long displays
2551 processID (attach) interpretation of 2nd GDB cmdline arg
2553 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
2555 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
2556 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
2557 breakpoint.c, main.c: lint.
2559 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2561 Install new configuration scheme for GDB and friends.
2563 * config.sub: Translate ordinary names to three-part names.
2564 * configure: Use three-part names internally.
2565 * configure.in: Translate three-part names to filenames.
2567 * README, WHATS.NEW: Update for gdb-4.0.
2568 * Makefile.in: Roll VERSION to 3.99.
2570 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
2572 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
2573 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
2574 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
2575 to single structures rather than arrays; when passing
2576 their address, use &. This avoids trouble with bdead compilers.
2577 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
2578 instead. This avoids portability headaches.
2579 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
2581 * source.c (open_source_file): Avoid ANSI const bdeath by
2582 skipping declaration and then casting result value.
2583 * tm-hp300bsd.h: Clarify comment.
2584 * utils.c (strstr): Result is const char *; ANSI bdeath.
2585 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
2586 since system include file defines it differently from "defs.h",
2587 though the two are equivalent for our purposes.
2588 * tconfig/hp300bsd: Add m68k-tdep.o.
2590 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
2592 * tconfig/sun*4: Remove warnings about system assembler.
2594 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2596 * mcheck.c: Avoid warning about undeclared abort fn.
2597 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
2598 it causes recursive calls to error() when used in cleanups.
2599 To do so requires that we make it a function, so we do.
2600 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
2601 * utils.c (do_cleanups): Remove the current cleanup from the
2602 chain *before* calling it, in case error() is called from it.
2603 The result won't be pretty, but won't be an infinite loop either.
2605 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
2607 * dbxread.c (read_struct_type): Grok anon structs for C++.
2608 (vb_name, vptr_name): Null terminate these strings.
2610 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2612 Minor bug fixes from BSD Net2 gdb:
2614 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
2615 returns 0, there is no previous frame.
2616 * breakpoint.c (commands_command): If !from_tty, don't call
2617 input_from_terminal_p().
2618 * dbxread.c (record_misc_function): Speed up slightly.
2619 (compare_psymbols): Ditto.
2620 * infcmd.c (do_registers_info): Take a second argument to
2621 determine whether to print float registers. "info registers"
2622 does not do so anymore. "info all-registers" does, now.
2623 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
2625 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
2626 * inflow.c (initialize_inflow): Set tflags_ours correctly.
2630 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
2631 executing_breakpoint_commands if we are interrupted by error.
2632 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
2633 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
2634 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
2635 catch_errors() so we can setup the frame regardless of whether
2636 the shared libs work.
2637 * ieee-float.c (double_to_ieee_extended): Get exponent from
2638 right place in little-endian systems. From John Carey.
2640 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2642 * main.c: Remove unused terminating_signals and catch_termination().
2643 (long_options): Terminate with a zero element.
2644 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
2645 (gdb_readline): Make call-compatible with readline.
2646 (init_signals): Improve comments re vfork vs. signal.
2648 * utils.c (prompt_for_continue): Use new gdb_readline().
2649 If we prompt for continuation, we don't let CR repeat the previous
2650 command, once we get back to a prompt. It's too easy to keep
2651 hitting CR, expecting "--more--" prompts, and have some long
2652 command start repeating on you.
2654 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2656 * blockframe.c (frameless_look_for_prologue): Speed up by
2657 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
2658 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
2659 Define two variants, one faster.
2660 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
2661 and return zero, rather than giving an error.
2662 (setup_arbitrary_frame): Initialize the PC in the new frame.
2663 (skip_prologue): Add a second arg saying whether we're just
2664 checking for a frameless function or not.
2666 * core.c (core_open, core_close, core_xfer_memory): Move
2667 section table pointers and bfd* into the target_ops.
2668 (core_open): Allow errors in shared lib reading, etc.
2669 (core_files_info): Describe shared library sections.
2671 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
2672 exec_files_info, set_section_command): Move section table
2673 pointers and bfd* into the target_ops.
2674 (add_to_section_table): Add BFD to section table.
2676 * target.c (target_xfer_memory, target_info): Pass target to
2677 xfer_memory and target_info functions.
2680 * gdbcore.h: Move struct section_table.
2681 * target.h: New home of struct section_table.
2683 * solib.c (solib_add): New argument is the target_ops whose
2684 section list is to be added to, if any. Reallocate the
2685 sections in that target to add any that come from shared libs.
2686 (throughout) so_sections renamed to sections.
2687 (solib_xfer_memory): Deleted.
2688 * tm-sunos.h (SOLIB_ADD): Add target argument.
2689 (SOLIB_XFER_MEMORY): Delete.
2691 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2692 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
2693 from target_ops. It's the same on all targets. Add two section
2694 pointers to target_ops.
2696 * stack.c (find_relative_frame): Dump ancient algorithm for
2697 "down", just use handy "next" pointers.
2698 (frame_command): Don't error if there is no stack; let user
2701 * inflow.c (new_tty_prefork, new_tty): New prefork routine
2702 modifies static state in the parent process; new_tty itself
2703 runs in the child and modifies the child's file descriptors
2704 to match the saved static state.
2705 * infrun.c (child_create_inferior): Call new_tty_prefork,
2708 * infptrace.c (child_xfer_memory): Add ignored target arg.
2709 * remote-eb.c (eb_xfer_inferior_memory): ''
2710 * remote-nindy.c (nindy_xfer_inferior_memory): ''
2711 * remote-vx.c (vx_xfer_memory): ''
2712 * remote.c (remote_xfer_memory): ''. Rename from
2713 remote_xfer_inferior_memory.
2715 * main.c (main): Only try to attach "corefile" argument if
2716 it starts with a digit.
2718 * symfile.c (symbol_reloading): New "set/show" variable.
2719 (symbol_file_add): Shorten message about symbol reading.
2720 (add_symbol_file_command): Merge with add_syms_addr_command,
2721 since this should work on all targets now.
2722 (stop_whining): Default to zero, to shut up complaints
2723 about bad symbol tables on many systems.
2724 (free_named_symtabs): Just exit unless symbol_reloading.
2726 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
2727 and add comment explaining shared library screw.
2729 * source.c: #if defined => #ifdef.
2731 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2733 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
2735 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2737 * doc/rdl-apps.texinfo: provide default readline-appendix finder
2738 (doc/Makefile knows how to make one for local config)
2740 * Makefile.in: use doc/Makefile for doc targets
2742 * doc/Makefile: GDB documentation now has its own Makefile
2743 doc/refcard.tex: renamed from "gdbrc.tex"
2744 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
2745 doc/gdbint.texinfo: add markup in "Cleanups" chapter
2748 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2750 * values.c (baseclass_addr): When reading target memory, use the
2751 length of the basetype, not the upper type. We've only malloc'd
2752 enough space for the basetype, leading to errors in free().
2754 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
2755 ends up as a function specially, since we know the actual type of
2756 the pointed-to address. This (somewhat) fixes display of
2757 expressions that include misc_function_vector names. Try `cond 1
2758 !strcmp("a","b")' then `i b'.
2760 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
2761 The child can be proceeded from inside wait_for_inferior in
2762 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
2763 getting skipped in that case.
2765 * expprint.c (print_subexp): Use filtered output, since the
2766 subroutines we call use it, otherwise the output is horribly
2767 mangled, since output of wrappable stuff comes out late.
2769 * Makefile.in: Bump VERSION to 3.98.1
2771 * infrun.c (child_create_process): Use execlp to find the
2772 shell to exec our target program. This requires some fiddling
2773 with `environ' since there is no execlpe().
2775 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2777 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
2778 Minor rearrangement of refcard permits two new make targets--
2779 gdbrc.dvi DVI output for refcard, using CM fonts
2780 gdbrc.ps PostScript refcard, using PS fonts
2782 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2786 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
2787 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
2789 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2791 * doc/gdb.texinfo: last changes for release.
2792 Minor typo and formatting fixes; incorporated most fixes remaining from
2793 filed mail commenting on earlier drafts.
2795 Added warnings: pipes don't work in run command;
2796 conditions are converse of assertions;
2797 step over fn without debug info goes to next fn;
2798 vars may have "wrong" values near fn entrance, exit
2800 Added example from Kingston on printing repeated nonadjacent values
2802 Added explicit mention that in Emacs gdb mode C-c and C-z are like
2803 shell mode for signals
2805 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
2806 doesn't sound so much like its parent "Stopping and Continuing"; also
2807 moved entries on continue to top of section, so they don't get lost.
2809 Improved installation directions in appendix, added manual formatting
2812 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2814 * configure.in: Remove xm.h and tm.h even if we aren't linking
2815 new ones, so "./configure sun4; ./configure none" does the right
2816 thing. Assume that alldeps.mak and depend are already built in
2817 srcdir, and avoid running "make" (particularly "make depend",
2818 which involves "gcc") from inside configure. Build Makefile
2819 directly rather than building Makefile.conf first.
2820 * configure: Regenerate with above changes.
2821 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
2822 to 3.98. Revise gdb.tar.Z procedure to produce a file
2823 called gdb-$(VERSION).tar.Z but which unpacks into a
2824 directory called "gdb". Move non-source files out of
2825 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
2826 (depend): Don't try to do "gcc expread.y".
2827 (expread.o): Update dependencies by hand.
2829 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2832 Fixed a variety of small typos that prevented info from formatting
2833 cleanly; altered too-long heading for GPL Appendix, as discussed
2834 w/RMS; Changed date on cover to July 91.
2836 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2839 (1) Applied some fixes due to comments from Larry Breed (easier ones
2840 through chapsec 5.2)
2841 (2) Eliminated use of @footnote---had my doubts about it anyways, and
2842 it's broken in latest texinfo
2843 (3) Introduced *some* use of [] for optional arguments, where
2844 explanation is not simpler by listing cmd w arg and cmd w/out arg
2845 separately. Still not using @deffn.
2846 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
2847 couple of headings are too long. Need patches to texinfo or revision
2850 * Partial update to README (which still needs work for this
2851 release!): (1) use of configure corrected for new script,
2852 (2) "make gdb.dvi" and "make gdb.info" mentioned.
2854 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
2856 * symtab.c (lookup_symbol): Don't complain right off about
2857 no debug symbols; use the misc function vector first.
2858 (list_symbols): Use misc function vector to find symbols
2859 that don't have debug info, and print them.
2860 (find_pc_symtab): Temporarily avoid fatal() when psymtab
2861 PC range doesn't match symtab PC range, as it does on the
2862 MIPS because our symtab reading isn't perfect.
2864 * dbxread.c (dbx_symfile_read): Make warning about
2865 "no debug symbols" slightly nicer.
2867 * source.c (select_source_symtab): If "main" symbol exists,
2868 but decode_line_spec can't find line info, don't just return
2869 a zero; try other source symtabs or give an error.
2871 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
2872 their low addresses first, then rip through fixing high addrs.
2874 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
2875 <runene@ifi.uio.no>.
2876 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
2878 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2880 * Minor, mostly mechanical, cleanup of doc subdir for clean
2881 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
2882 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
2884 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
2886 Mostly MIPS and general symbol-reading fixups.
2888 * doc/gdbint.texinfo: Add documentation on symbol-reading
2891 * mipsread.c: Remove kludges around #include "ecoff.h".
2892 Remove redefinitions of a_magic, etc, no longer used.
2893 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
2894 Fix global overview comments to match symfile.c protocol.
2895 (mipscoff_new_init): Eliminate cur_hdr if we have one.
2896 (mipscoff_symfile_read): Eliminate unused code. Avoid
2897 sorting all the symtabs, when all we have read here is psymtabs.
2898 The symtabs are sorted as they are created anyway. Tell
2899 condense_misc_bunches whether we're mainline.
2900 (psymtab_to_symtab_1): Pass filename when recursing, to make
2901 stack trace more informative.
2902 (parse_partial_symbols): Assume cur_hdr as argument.
2903 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
2904 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
2905 the TYPE_NAME of char *, since that's done in symfile.c.
2906 (free_numargs, parse_symbol, add_symbol, add_block,
2907 shrink_linetable): Declare these fns void.
2908 (upgrade_type): Convert tree of if's to switch. Clean up
2909 bogus "off == 0" handling with a complaint. Avoid setting
2910 field bitpos and bitsize of array with lower and upper bounds.
2911 Check specified bitsize of elements against their actual type's
2912 bitsize, and complain if different. Complain about unknown
2914 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
2915 (psymtab_to_symtab_1): Print names of subsidiary files that
2916 are being read in. FIXME, we read far too many files. This code
2917 is not the problem, the problem is in parse_fdr where the psymtabs
2919 (cross_ref): Result should indicate that we used one aux entry
2920 normally, or two if we encountered a "next" entry. This used
2921 to leave the caller pointing at the wrong aux entry.
2922 (add_symbol): If overflowed cur_block, reallocate it larger,
2923 chase all pointers to it, and complain(), rather than clobber memory.
2924 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
2925 (new_field): Only allocate one field initially, not two.
2926 Pull ++ out of macro argument. Simplify.
2927 (_initialize_mipsread): Avoid initialization of importd
2928 global_psymbols and static_psymbols.
2930 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
2931 to properly set pst->symtab; avoid searching for it.
2932 (symfile_fns): Improve comments, add a FIXME.
2933 * dbxread.c: Update comments to reflect symfile protocol.
2934 (read_ofile_symtab, end_symtab): Return the symtab.
2935 (psymtab_to_symtab_1): Set pst->symtab.
2937 * coffread.c (coff_symfile_read): tell condense_misc_bunches
2938 whether we're mainline.
2940 * symfile.h (sym_fns): Remove unused sym_discard member.
2941 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
2943 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
2944 the environment variable is not.
2945 * infcmd.c (finish_command): Use filtered printfs.
2946 * cplus-dem.c: Add struct tags to a few unnamed structs.
2947 * valops.c (value_coerce_array): Improve comments.
2948 * valprint.c (type_print_varspec_suffix): Print array size only
2949 if greater than zero.
2950 * m88k-tdep.c: Shift some lines left by one space, that had
2951 apparently been trashed at some point.
2952 * TODO: More things to do, a few got done.
2954 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2956 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
2957 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
2959 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
2960 * expread.y, findvar.c, symmisc.c: Ditto.
2961 * printcmd.c (address_info): Update printed forms of LOC_
2962 symbols. Elim LOC_EXTERNAL.
2963 (print_frame_args): Keep track of param stack offsets before
2964 re-looking up to find the local register param is kept in.
2966 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
2967 Further integration of mipsread into gdb. Eliminate unused
2968 routines, duplicate declarations. Handle static symbols in
2969 psymtabs as well as external symbols. When reading symtabs,
2970 insert symbols into the correct block (global, static, or a local
2972 (read_mips_symtab, parse_partial_symbols): Don't pass useless
2974 (mipscoff_symfile_read): Don't call select_source_symtab.
2975 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
2976 rather than SYMBOL_VALUE.
2977 (parse_external): Comment clobbering of top_stack.
2978 (parse_partial_symbols): Update comments. Allocate and parse
2979 static symbols as well as external symbols. FIXME, enum values
2980 are not handled in this pass, but should be. Inline new_psymbol.
2981 Use SYMBOL_VALUE_ADDRESS.
2982 (psymtab_to_symtab_1): Read symbols into global static block
2983 by default (until enter some function's local block context).
2984 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
2985 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
2987 * source.c (select_source_symtab): Select a source symtab
2988 from either the symtabs or, failing that, the psymtabs.
2989 (list_command): Update error message.
2990 (forward_search_command, reverse_search_command): Use getc, not
2991 fgetc, for speed. FIXME, add comment about buffers that die if
2992 overrun by long line.
2994 * values.c (unpack_field_as_long, modify_field): Avoid shifting
2995 by an entire word, which is not portable, if we have a 32-bit
2996 field. (Code in dbxread.c already turns such bitfields, if
2997 aligned, into ordinary ints, but fixing this will help for other
2998 symbol formats and for future changes.)
2999 * core.c (core_open): Handle ANSI const brain death.
3000 * utils.c (vprintf): Fix varargs typo.
3002 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3004 * findvar.c (find_var_value): Handle &function better.
3005 * TODO: Document work needed on &fn and &array.
3006 * printcmd.c (print_address_symbolic): New arg is the prefix
3007 to print if a name is printed.
3008 (print_address_demangle): Honor "set print address" now.
3009 Use new arg above to improve spacing of output.
3010 * valprint.c (val_print): When printing function pointers,
3011 print symbolic form too.
3012 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
3014 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3016 * core.c (memory_error): Reword error msg to mislead less.
3018 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
3020 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
3021 parse_partial_symbols): Use newer BFD internals (external_filehdr
3022 and external_aouthdr), byte-swap the fields that we care about
3023 before using them, and make the file header data local to
3024 read_the_mips_symtab rather than global.
3026 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
3028 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
3029 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
3031 * main.c (command_line_input): Flush stdout and stderr
3032 before every call to readline. This reportedly fixes a bug
3033 that comes up in Sys V running emacs-gdb and/or xxgdb,
3034 when stdin/out are pipes or sockets.
3036 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
3038 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
3039 Avoid declaring Makefile dependencies, because GNU Make stupidly
3040 tries to update it if we do.
3042 * coffread.c: Revise for minor changes to bfd internal coff
3045 * configure: If -template= is given a relative path, make it
3046 absolute before recurring in subdirectories.
3048 * configure, configure.in, Makefile.in: Install "configure" script
3049 as replacement for config.gdb.
3050 * config.gdb, Makefile.dist, Makefile.sdir: Remove
3051 * README: Update for configure, mostly. FIXME.
3053 * Add dec3100 as equivalent to littlemips. Indicate in all host &
3054 target config files that they are for the host. When the lines
3055 get copied into the Makefile, this makes it more obvious what's
3058 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3060 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
3061 tabs, which end up in the disassembler output inadvertently.
3063 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
3065 Make it compile cleanly in an ANSI GCC2 environment.
3067 * blockframe.c: <stdio.h>
3068 * cplus-dem.c: free takes a void *, ifdef __STDC__
3069 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
3071 * defs.h (alloca): Avoid doing anything if alloca already def'd.
3072 * stddef.h, stdlib.h: Remove these files.
3073 * symtab.c: Avoid declaring qsort, close.
3074 * symfile.c: Avoid declaring close.
3075 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
3076 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
3078 Assorted other changes.
3079 * dbxread.c: include "libaout.h", not "liba.out.h".
3080 * printcmd.c (print_frame_args): Set recurse properly for
3081 indentation of struct and array parameters.
3082 * valops.c (value_cast): Allow cast to void.
3083 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
3084 single_step() in a target-independent fashion.
3085 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
3086 set up to be ready to continue. This makes us target independent.
3087 * infptrace.c (child_resume): Remove call to single_step; now
3088 can single step a SPARC target of any kind.
3090 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
3092 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
3093 docn into separate sections---basically chapters, plus two loose
3094 pieces that can be configured to go in different places. This
3095 allows GNU m4 to preprocess the manual without coredumping.
3097 * Makefile.dist: tell TeX where to find texinfo.
3099 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
3101 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
3102 the new target "rdl-apps.texinfo" which captures the Makefile
3103 variable that records where to find the Readline libraries.
3105 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
3107 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
3108 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
3109 * defs.h (const, volatile): Only define if not already defined.
3110 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
3112 * README: Update for release 3.95.
3113 * config.gdb: Don't create readline dir in subdir builds.
3114 * main.c: Include with "..." form for non-system include files,
3115 so "gcc -MM" for "make depend" works.
3116 Include readline files with "...h" rather than <readline/...h>.
3117 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
3119 * coffread.c: Undo minor damage done by Rich Pixley. Use
3120 different internal and external representations of COFF
3121 data structures. Use new BFD routines for swapping them in and
3123 * symfile.c (free_named_symtabs): Avoid freeing file names that
3124 are null or empty. Old i960 tools seem to produce files that
3125 claim to have empty names, causing each successive file read
3126 to blow away the previous one.
3127 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
3128 Move deferred_stores to top of file, but don't separate its
3129 #define's from its variable. Add commentary.
3130 * Makefile.dist: Fix Rich damage; undo "configure" changes in
3131 favor of keeping the (working) config.gdb. Move readline
3134 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
3136 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
3138 * infptrace.c (fetch_registers): no result, since now void.
3139 * tconfig/news: target depends on m68k-tdep too.
3141 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
3143 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
3146 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
3147 applied various small fixes due to or inspired by RMS comments
3149 * doc/gdb.texinfo: finished using all RMS comments, save those for
3150 appendices on readline and cmd history (which are in other source
3153 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
3155 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
3156 chapter 9; (2) documented 'break' command's menu mode for
3157 overloaded names, in response to hgs problem report C++ p-31
3159 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
3161 * doc/gdb.texinfo: (1) better introductory example; (2) more
3162 consistent use of @code, @samp, @file, @kbd throughout; small
3163 cleanups to first three nodes; (3) new "Contributors" node;
3164 (4) Appendix, Renamed Commands; (5) divert specialized startup
3165 instructions to "Targets" chapter for generic manuals, while
3166 leaving them up front for manuals specific to specialized
3167 environments; (6) apply fixes from RMS comments through chapter 4.
3169 * pretex.m4: modify explanatory text slightly (and redefine
3170 "regexp") to keep GNU m4 from complaining. (It still crashes
3171 later, but one step at a time...)
3173 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
3175 * readline/readline.c (update_line): Avoid dereferencing a pointer
3176 before comparing it to its bounds. Saber caught this.
3177 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
3178 and only set PC if tgetstr returned non-null. Saber caught this.
3180 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
3182 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
3183 stuff for config manual) here where it counts; updated
3184 to use new subdir structure (gdb/doc/).
3186 * Makefile: generated from above via
3190 * gdbint.texinfo: added instructions on generating gdb.info* files
3191 locally for release. These are ordinary info
3192 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
3193 Makefile)---but due to use of texinfo 2, can't count on makeinfo
3194 to generate these, so we distribute them already formatted.
3196 * gdb.texinfo: included full Info node and menu crud (as generated
3197 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
3199 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
3200 put in comments-for-future gdb.info target (one day makeinfo will
3203 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
3205 * gdb.texinfo: Updated to include new or old undocumented
3206 commands, at least the following (perhaps some others I forgot to
3207 record): info f, info float, info path, info program, info s, info
3208 set, info source, info terminal, info types, info user, set/show
3210 Also covered all recent GDB command renames for v4.
3212 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3214 * mipsread.c: Rather than keeping count of how many symtabs
3215 and psymtabs we have, for sorting purposes, count them when
3216 we need to sort. This fixes bug in rereading of symbol tables.
3218 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
3220 * infcmd.c: renamed "info path" to "show paths"
3221 * gdbrc.tex: documented above.

3231 Fix up "saber_gdb" to work again.
3232 * saber.suppress: Update.
3234 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
3235 symtab.h, target.c, target.h: Lint.
3236 * core.c: setup and select frame after reading shared libs,
3237 else reading shared libs will clobber them. Lint.
3238 * utils.c (error): Force out any buffered wrap text.
3240 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
3242 * remote.c: Remove decls of memory_insert_breakpoint
3243 and memory_remove_breakpoint, no longer used. (Suggestion of
3246 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
3247 to make it easier to interface to "configure"'d libraries.
3249 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
3251 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
3252 aliases for set/show print.
3254 Thu May 2 11:22:02 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

3294 * {x,t}config/m88k ({X,T}DEPFILES): Add missing files.
3296 * mtrace.c: Don't typedef things like size_t, just #define them.
3298 * coffread.c [TDESC]: #if 0 out references to coffsyn.
3300 * symtab.h (struct symtab): Include EXTRA_SYMTAB_INFO.
3301 tm-88k.h: Define EXTRA_SYMTAB_INFO.

3304 dc_dcontext_t not int.
3306 * coffread.c [TDESC]: Use system include files not <intel-coff.h>.
3308 * coffread.c [TDESC]: Move setting of debug_info from
3309 coff_symfile_read to find_linenos and make it work with BFD.
3311 * cplus-dem.c [__STDC__]: Make x{m,re}alloc return void*.
3313 * signame.c: Cast const char* to char* when assigning to sys_siglist.
3315 * utils.c (strsave): Make arg const char* not char*.
3317 * infrun.c (wait_for_inferior) [SHIFT_INSN_REGS]: Use
3318 bpstat_explains_signal (stop_bpstat) not stop_breakpoint.
3320 * tm-88k.h (START_INFERIOR_HOOK): Make tdesc_handle a dc_handle_t.

3338 Mips bringup and general cleanup
3340 * cplus-dem.c: Move CPLUS_MARKER define to after defs.h.
3341 * infptrace.c (PT_WRITE_D, PT_READ_D): Use correct values.
3342 (This still doesn't seem to make MIPS bkpts work.)
3343 * mipsread.c: Remove dup "Reading symbol data..." msg.
3344 (symbol_file_command, add_file_command): Remove, obsol.
3345 * printcmd.c (ptype_command): Say "an enum" rather than "a enum".
3346 Wrap output appropriately.
3347 * stack.c (locals_info, catch_info, args_info): Check
3348 selected_frame rather than target_has_stack or coredumping.
3349 * valprint.c (type_print_varspec_suffix): Wrap "ptype" output of
3350 enums appropriately.
3352 Wed May 1 14:10:22 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
3354 * signame.c: Include defs.h and param.h.
3356 * cplus-dem.c: Include defs.h and param.h.
3357 Makefile.dist: Don't hack in the "param.h".
3358 param.h: Don't include defs.h.
3360 * expread.y: Use a union to deal with the fact that type_stack
3361 can have both ints and enum type_pieces in it.
3362 ({push,pop}_type_int): New functions.
3364 Tue Apr 30 13:18:58 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

3376 symtab.c, cplus-dem.c, value.h, expread.y, valprint.c,
3377 copying.awk, solib.c, inflow.c, symmisc.c
3378 : Lint. Use read_memory not read_memory_integer on CORE_ADDR's.
3379 Use {value_as,unpack}_pointer (added to values.c)
3380 not {value_as,unpack}_long on CORE_ADDR's.
3381 Use longest_to_int (added to defs.h) instead of cast to int.

3851 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
3853 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
3854 is the first symbol read, even if not mainline.
3855 (dbx_psymtab_to_symtab): symfile might be zero, cope.
3856 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
3857 (set_section_command): New command ("section xxx yyy" -- should
3858 be renamed to "set section xxx yyy" FIXME) which sets the
3859 base address of a section of the exec file, overriding the
3860 virtual address that BFD reports.
3862 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
3864 * exec.c: Add add_syms_addr_command to exec_ops, so you can
3865 load symbols at any address while examining an exec file.
3867 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3869 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
3870 for printing the float info is host-dependent, not
3871 target-dependent. FIXME.
3872 * i386-pinsn.c: Move #includes to top, remove useless ones.
3873 * i386-tdep.c: Don't bother including <.../reg.h> since we
3874 don't use it (and it doesn't exist on host systems).
3876 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
3877 Convert negative numbers properly.
3878 (ieee_test): Make numbers really random; fix format arg.
3880 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
3881 * core.c (core_detach): Unpush core_ops, which might not be on
3882 top. We used to just pop the top, which broke things. Don't
3883 need dont_repeat() any more.
3884 (core_file_command): Psst! Don't repeat it.
3885 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
3886 * expprint.c (print_subexp): Avoid switch fallthru on
3887 BINOP_ASSIGN_MODIFY, so we can print += and such.
3888 * frame.h: Fix typo.
3889 * inflow.c (kill_command): After killing inferior, print our
3890 current frame in the core file, if we have one.
3891 (generic_mourn_inferior): When inferior dies, either select
3892 the current frame (in the new target, e.g. core file), or
3893 set both the current and selected frames to NULL.
3895 Changes from Peter Schauer.
3897 * infptrace.c: Avoid <sys/ptrace.h> on USG.
3899 * Make all file names fit in 14 characters (sigh and damn!):
3900 mv hp300hpux-xdep.c hp300ux-xdep.c

3908 mv remote-sa.m68k.shar rem-m68k.shar
3909 mv remote-multi.shar rem-multi.shar
3910 * Makefile.dist, README, config.gdb, convex-pinsn.c,
3911 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
3912 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
3915 * command.c (user_info_1, user_info): New command for listing
3916 the user-defined commands.
3918 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
3920 * dbxread.c (really_free_pendings): Clear file_symbols
3921 and global_symbols after freeing them; otherwise, running
3922 this function twice (if it appears twice on the cleanup
3923 chain), we try to free things twice.
3925 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
3926 based on text_addr (the address of text in core), not on addr (the
3927 offset between text in the .o file and in core). This change
3928 is from Peter Schauer.
3930 * main.c: Define ALL_CLEANUPS as a cast of zero.
3931 (return_to_top_level): Use it.
3932 (main): Do all cleanups after each command run as part
3933 of the gdb startup sequence. Also do all cleanups before
3934 entering the command loop, and every time we exit the command
3935 loop and reenter. Before, the cleanups from the startup sequence
3936 were being left undone until the first error!
3937 (command_loop): Rename do_nothing cleanup to command_loop_marker
3938 so we can see it easily when examining the cleanup chain.
3939 (init_signals): Add another do_nothing for signal handling.
3940 (quit_command): Only try to kill target if it has execution.
3941 Problems in the target stack got us into a state where
3942 inferior_pid was nonzero but none of the targets had execution.
3943 In this state you couldn't exit gdb.
3945 * dbxread.c: Two changes from Peter Schauer.
3946 (echo_command): Fflush output after an echo command.
3947 (show_history): Pass all args to cmd_show_list.
3949 * utils.c (init_malloc): Call mtrace to turn on tracing
3950 if the environment variable MALLOC_TRACE is set to a file name.
3951 * mtrace.c: Add source file which provides a log of every malloc,
3952 free, and realloc to a trace file.
3953 * mtrace.awk: Add source file which analyzes the trace file.
3954 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
3955 (VERSION): Roll to 3.94.3.
3957 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
3958 (check_duplicates): Don't bother with watchpoints.
3959 (set_raw_breakpoint): Comment about danger of this routine.
3960 (watch_command): Parse and eval all args before calling
3963 * solib.c (find_solib): Avoid error in referencing memory to
3964 see if any more shared libraries have been added. This is
3965 particularly useful if the target has terminated. Bug reported
3968 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
3969 in bringing up 3.94.2 on the Sun-3.
3971 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
3972 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
3973 expression (in scope) before reenabling watchpoint.
3974 * signame.c (init_sigs): Add missing declaration of i, fix
3975 sys_siglist declaration.
3976 * source.c (list_command): Fixed range computation to use
3978 * stack.c (backtrace_command): Do not allow command if target has
3979 no stack, print informative error message.
3980 * target.c (target_command): Do not write into command line
3981 because this fails if the target command is used in a user defined
3982 command. [This change was enhanced by gnu to support any-
3983 unique-prefix matching on target names.]
3984 * valops.c (value_struct_elt): Avoid infinite loop on an
3985 erroneous attempt to print the member of function (try p main.p).
3987 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3989 * expread.y (name_no_typename): Avoid reduce/reduce errors
3990 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
3991 Since the GDB parser really doesn't use name_no_typename in a
3992 name-only context, the parser can't tell the diff between
3993 names and numbers here. Avoid allowing a name_no_typename
3994 to be a NAME_OR_*INT to resolve the conflict.
3996 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3998 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
4000 * valprint.c (val_print_fields): bitfield printing didn't handle
4001 byte order. Indirect through a few more fns to cope.
4003 * values.c (modify_field): also cope with byte order.
4005 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
4007 Cleanup for release 3.94.2:
4009 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
4010 include files. Roll version to 3.94.2.
4012 * coffread.c (init_stringtab): Read length into unsigned char
4013 array before swapping; don't assume 32-bit longs.
4015 * target.c (target_info): Don't bother with get_sym_file, just use
4016 the symfile global variable.
4017 * symtab.h, symfile.c (get_sym_file): Delete it.
4019 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
4020 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
4021 (read_type): Replace one more error() with complain().
4023 * mipsread.c (parse_partial_symbols): Replace printf with complain.
4025 * i960-tdep.c: Fix copyright attribution.
4027 * config.gdb: Quote all backquotes in doublequotes. You can
4028 quote me on that. BSD 4.4 shell found this one.
4030 * infptrace.c (throughout): The third argument to ptrace is an
4033 * infrun.c (wait_for_inferior): When program has terminated, we
4034 have to call target_terminal_ours before we pop that target off
4035 the stack (e.g. before a call to target_kill or
4036 target_mourn_inferior). This fixes problem where a program
4037 terminates, then GDB stops for (tty output) and you have to type
4038 "fg" to the shell to resume it. FIXME: This code for what to
4039 do after termination really should be in normal_stop instead.
4041 * gdbcore.h (read_memory_check): Change declaration; it changed
4044 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
4045 4.4 prereleases, this avoids a bug in their sgtty compatability
4047 * remote.c: Use terminal.h rather than hand-rolling the same.
4049 * signame.c, signame.h (psignal): Arg is unsigned, not int.
4050 * utils.c (strsave, strstr): Fix arg types.
4051 * valprint.c (val_print): lint
4053 MIPS symbol table support from Per Bothner:
4055 * symfile.c (symtab_fns): Remove initializer table that needs to
4056 be hacked for each new symbol file format supported.
4057 (add_symtab_fns): New function, chains symbol table
4058 handlers into the global list.
4059 (symfile_init): Search this list.
4060 * symfile.h: Add next pointer, declare add_symtab_fns.
4061 * coffread.c (_initialize_coffread): Call add_symtab_fns.
4062 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
4064 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
4065 symbol *). Thus, we no longer need the hack to trash
4066 pst->filename. Good, since that hack confused code in symfile.c!
4068 (reorder_symtabs, destroy_all_symtabs): Removed static
4069 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
4070 Instead, the latter now uses a temporary array (stack-allocated
4071 from an obstack, and then freed).
4073 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
4074 haven't been set in the outermost stBlock of a procedure. This was
4075 a problem with f77 binaries on Ultrix 4.?.
4077 (new_symtab, new_symbol, new_type): Continue changing code to use
4078 obstacks more and otherwise conform to dbxread internal style.
4079 Made the free_code of symtabs be free_linetable (as in dbxread)
4080 instead of free_contents. This implies memory leaks when reading
4081 a new symbol table, until the conversion is finished. Did change
4082 (struct symbol) and (struct type) to be allocated on the
4083 symbol_obstack. Blocks and blockvectors are among the things
4086 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
4087 tested much, but it solved one problem (reported by Meissner), and
4088 cleans up some other things. The problem happened when an
4089 included file contains actual code (functions) and not just
4090 definitions. The mips coff is a little inconvenient there, since
4091 it may cause a procedure to be mapped to the wrong psymtab.
4093 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
4094 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
4095 this will need work for the new core paradigm.
4097 Opcode patches from the net:
4099 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
4100 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
4101 missing altogether - they are added here. From Bruce Bauman.
4102 * mips-opcode.h: The low mask for C0 instructions was too small.
4103 From Garrett Lau. I modified the fix to check the entire 32-bit
4106 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
4109 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
4111 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
4113 * dbxread.c (read_type): Pointer subtraction (value_sub in
4114 valarith.c) sometimes failed because the types of the
4115 pointers being subtracted were not identical.
4116 These differed because dbxread.c was allocating pointer types
4117 using dbx_alloc_type+smash_to_pointer_type instead of
4118 lookup_pointer_type. I failed to find a justification for the
4119 former, so I changed it to use the latter. Similarly, I
4120 replaced smash_to_function_type by lookup_function_type,
4121 and smash_to_reference_type by lookup_reference_type.
4123 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
4124 _initialize_mipsread): corresponding changes.
4126 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
4128 * source.c (mod_path): Do tilde_expand on each component of the path,
4129 rather than on the (list of) paths as a whole.
4130 (print_source_lines): Set first_line_listed in addition to
4131 current_source_symtab and current_source_line. If the source was
4132 not findable, after a "dir" command to fix the problem,
4133 a "list" would get the wrong lines.
4135 While I was there... (gnu):
4137 * dbxread.c (read_type): Change error to complaint.
4139 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
4141 First attempt at detailed understanding of symbol table memory alloc.
4143 * dbxread.c (dbx_symfile_read): Free our string table if we
4144 aren't the mainline. Free the "info" struct since we're done with
4146 (init_psymbol_list): Free any previously allocated psymbol lists.
4147 (): FIXME: Should realloc-down the psymbol lists when done reading
4148 the main symbol file?
4150 * symmisc.c (free_symtab): Free fullname field too.
4152 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
4153 (REGISTER_ADDR): Make result type unsigned int.
4155 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
4156 define REGEX must also define REGEX1 (its dependency).
4158 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
4160 * tconfig/i960: No longer works, points you at vxworks960 or
4163 * xgdb.c, XGDB-README: Remove file. Users can get the much
4165 * Makefile.dist: Remove all trace of xgdb.
4167 * breakpoint.c (breakpoint_1): Pass demangle arg to
4168 print_address_symbolic.
4169 (clear_breakpoints): Remove unused function.
4170 (breakpoint_re_set_one): Guts of breakpoint_re_set.
4171 (breakpoint_re_set): Use catch_errors to do them all anyway.
4173 * gdb-int.texinfo (Host versus Target): Add section on what is
4174 a "host" feature versus what is a "target" feature.
4176 * infcmd.c (path_command, path_info): Handle the PATH variable
4177 (object search path) as conveniently as the source search path.
4178 * environ.c (set_in_environ): Set some vars in GDB's environment,
4179 in addition to the child's. PATH, G960BASE, G960BIN for starters.
4180 * source.c (mod_path): New function, from guts of
4181 directory_command, modifies a path. Used by path_command.
4182 (directory_command): Call it.
4183 * defs.h (strsave): Declare.
4185 * utils.c (sevenbit_strings): Add new printing option.
4186 (printchar): Use it.
4187 (strsave): Provide this handy helper routine.
4188 (set_width_command): Rename set_screen_width_command.
4189 (_initialize_utils): "set screen-width" => "set width";
4190 "set screen-height" => "set height"; add sevenbit-strings.
4192 * infcmd.c (do_registers_info): Print floating point registers
4193 in raw hex as well as float format, regardless of whether it is
4194 a "virtual" convertible register.
4195 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
4196 regs as a double, just in case it's being used that way.
4197 * values.c (unpack_long): Comment on array/function coercion.
4198 (unpack_double): Argument is in target byte order now. For
4199 integer arguments, just call unpack_long and float the result.
4200 * m68k-tdep.c: include defs.h for "const" handling.
4201 * remote-nindy.c: Use ieee-float stuff.
4202 (nindy_fetch_registers): Unpack double regs to host double, then
4204 (nindy_store_registers): Pack extendeds to host double, flip
4205 around by misusing unpack_double, send as target double.
4207 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
4208 zero, as when stopped at the first instruction of a process.
4210 * blockframe.c: Fix filename in comment (param.h => tm.h).
4211 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
4212 * tm-68k.h: Fix typos.
4214 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
4216 Changes from a bringup on the DEC Vax under Ultrix 4.0.
4218 * coredep.c (fetch_core_registers): Pass end-address of register
4219 section to register_addr as expected. Don't call supply_register
4220 if we'd just pass it garbage.
4222 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
4224 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
4226 * target.c (push_target, target_info): Cast enums to int for < or
4229 * stack.c (print_frame_info): Identify source file & line
4230 even if we can't print it.
4232 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
4234 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
4236 Clean up IEEE floating point support.
4238 * ieee-float.h: New file.
4239 * ieee-float.c: Write real routines to convert between host
4240 doubles and various target IEEE extendeds.
4241 * m68k-xdep.c: Eliminate assembler code for extended floats.
4242 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
4243 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
4244 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
4245 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
4246 double_to_ieee_extended.
4247 * i960-tdep.c: Define ext_format_i960.
4248 * m68k-tdep.c: Define ext_format_68881.
4249 * sparc-tdep.c: Define ext_format_sparc, though unused.
4250 * Makefile.dist (HFILES): Add ieee-float.h.
4251 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
4254 Obsolete the "coffstrip" program in favor of using BFD's strip.
4256 * nindy-share/coffstrip.c: Remove file.
4257 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
4258 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
4259 * tconfig/nindy960: Remove reference to coffstrip.o.
4261 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
4263 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
4265 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
4266 * dbxread.c: Remove static symfile_bfd.
4267 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
4269 * inftarg.c (child_detach): Pop the child_ops vector if the
4270 detach is successful.
4271 * remote-nindy.c (nindy_create_inferior): Don't push a new
4272 nindy_ops since nindy uses the same one for execution and memory
4274 * core.c (core_ops): Use child_attach and child_create_inferior
4275 rather than default attach and create_inferior functions.
4277 Handle floating point registers in core files.
4279 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
4280 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
4281 This version untested since BFD doesn't yet support sun3 core
4283 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
4284 conventions. Fix comments and style. This version has not
4285 been compiled yet, since we have no HP inhouse.
4286 * core.c (get_core_registers): Look for two sections, ".reg"
4287 and ".reg2", and pass both to fetch_core_registers sequentially.
4289 Revise directory path yet again.
4291 * source.c (forget_cached_source_info): Not static any more.
4292 (init_source_path): New default source path is "$cdir:$cwd".
4293 (dir_command): Handle variable arguments ($cdir, $cwd).
4294 (source_info): Print "Compilation directory" rather than
4295 "Originally compiled in" to remind people of $cdir.
4296 (openp): If the path contains $cwd, use current directory.
4297 (open_source_file): If compilation directory is known, replace
4298 first $cdir in path with the compilation directory.
4299 (print_source_lines): Even if we can't print the lines, set the
4300 current symtab and line for future commands like "info source" or
4301 "breakpoint". Also, error message now contains the file name,
4302 line number, and file access error message.
4303 (_initialize_source): Fix help text to describe changes.
4304 * main.c (cd_command): Forget cached source info when we chdir.
4305 * utils.c (strstr): Add simple implementation.
4307 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
4309 * coffread.c (read_one_sym, init_linetable, init_stringtab):
4310 Byte-swap COFF symbol tables if necessary when reading them in.
4311 Use complain() to replace error message in one spot. Needs
4312 corresponding change in bfd/coff-code.h to make some symbol
4313 swapping routines non-static.
4315 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
4317 Merge changes from Eirik Fuller, for UTek.
4319 * defs.h (errno): Add declaration.
4320 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
4321 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
4322 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
4323 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
4324 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
4325 declarations of errno.
4327 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
4329 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
4330 <rpc/rpc.h> and <rpc/types.h>.
4332 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
4334 * i960-tdep.c (examine_prologue): Add new argument limit,
4335 which stops the scan at the end of the prologue, or at the PC.
4336 This fixes a problem where it walks down into the code for the
4337 user's statements if that code looks like function prologues.
4338 Mark Fox and I have been bouncing this code back and forth, making
4339 small changes to it. Callers changed to match.
4341 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
4343 Cleanup for gdb-3.94 release final:
4345 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
4346 the .c files from vx-share and nindy-share, from the various
4347 macros, since they are not found via ALLDEPFILES.
4348 (SFILES): Add tm-i960.h.
4349 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
4350 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
4352 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
4353 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
4355 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
4357 * am29k-tdep.c: Add contribution line.
4358 (examine_prologue): Cache information about function prologues in
4359 the misc-function-vector to avoid lots of references over the
4360 serial line while examining instructions.
4362 * core.c (core_close): New function made from cleanup_core.
4364 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
4365 remote-vx.c, remote.c, target.c, target.h,
4366 Update target_ops vector to add attach, close, and load entries.
4367 Use add_syms_addr_command, not add_file_addr_command, for
4368 add_file. Break out close routine from existing code.
4370 * dbxread.c (really_free_pendings): Don't free pending_blocks;
4371 they are in an obstack.
4372 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
4374 (define_symbol): Add symbol type parameter; change callers;
4375 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
4376 it to influence the symbol class on the i960.
4377 (define_symbol): Swap LOC_CONST's into target byte order.
4379 * exec.c (exec_close): New function.
4380 (exec_file_command): Call it.
4382 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
4383 Fix byte order of frame pointer.
4384 (read_var_value): Result of 0 if var's value can't be found,
4385 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
4386 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
4387 (locate_var_value): Use read_var_value and use its lazy address
4388 as the location of the var's value. Lint.
4390 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
4393 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
4394 obsolete Intel versions in favor of vxgdb versions.
4395 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
4396 code dealing with byte order of values, which Intel did in host byte
4397 order rather than gdb-4's target byte order.
4398 (i960_frame_chain_valid): Move to nindy-tdep.c.
4399 (examine_prologue, skip_prologue, frame_find_saved_regs,
4400 frame_args_address, leafproc_return, saved_pc_after_call,
4401 pop_frame): Add vxgdb versions from Mark Fox.
4402 (examine_prologue, frame_struct_result_address): Add code
4403 to deal with the saved value of G13 (struct return address
4405 (frame_args_address): Modify Mark's version to prefer the
4406 saved value over the current value in the topmost frame.
4407 Cache result in the frame info to avoid performance hair in
4409 (print_fault): Add gdb960 code for printing faults.
4410 (_initialize_i960): Actually call check_host.
4412 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
4413 add stub routines. FIXME, these currently just return zero!
4415 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
4416 (attach_command): Call target_attach, not target_open, now.
4418 * infrun.c (normal_stop): Make global, not static, for vx_attach.
4419 (child_attach): Rename from child_open.
4420 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
4421 don't confuse it with a zero step_resume_break_address.
4423 * inftarg.c (child_detach): Eliminate inferior_pid test.
4424 (child_files_info): Clean up message a bit.
4425 (child_ops): Use child_attach, not child_open, to attach.
4427 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
4428 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
4429 findvar.c to here, since it depends on the contents of the
4430 shadow_contents of breakpoints, but keep if #if 0 since it is
4433 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
4436 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
4437 (ptype_command, display_command): Eliminate have_inferior_p and
4438 have_core_file_p in favor of target_has_stack or
4439 target_has_execution.
4440 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
4441 code for actually finding the values of arguments, though we still
4442 keep track of the maximum stack offset for use in printing unnamed
4443 arguments. Handle missing FRAME_ARGS_ADDRESS.
4445 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
4446 (struct nindy_regs): Define registers passed to/from nindy.
4447 (nindy_fetch_registers, nindy_store-registers): Translate between
4448 nindy and GDB formats for the registers.
4449 (dcache_init): Statically allocate the cache, since it was being
4450 allocated by a malloc that was never freed anyway.
4451 (nindy_create_inferior): Error, not core dump, if no exec file.
4452 (nindy_before_main_loop): Use target_load, not target_add_file.
4454 * remote-vx.c (net_load): Specify large timeout for load
4455 requests. Allow user to break out with INTERRUPT.
4456 (net_break): Remove useless code, clean up. Change callers.
4457 (parse-args, skip_white_space, find_white_space): Clean up arg
4458 parsing to cope with quoted strings.
4459 (net_wait, net_quit): Never call error, just return status.
4460 (vx_read_register, vx_write_register): Cleanup status checking.
4461 #ifdef the code based on which CPU we are using (960 or 68k),
4462 FIXME, this should be completely general but it isn't yet.
4463 (vx_xfer_memory, vx_resume): Cleanup status checking.
4464 (vx_run_files_info): Improve message.
4465 (vx_load_command): Renamed from vx_add_file_command. Allow load
4467 (net_ptrace): Remove unused routine.
4468 (vx_wait): Adopt code from vxgdb960 to cope with broken
4469 connections to target machine and prompt to disconnect. Remove
4470 debug printouts. Map some EVENT_'s to SIGnals.
4471 (add_symbol_stub, vx_open): Print names of object files we found,
4472 and "ok" if we read their symbols OK. Clarify output in general.
4473 (vx_attach, vx_detach, vx_kill): Add these commands.
4474 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
4475 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
4476 "info files" output, and create_inferior, since we already have
4479 * stack.c (frame_info): Replace Frame_unknown with 0.
4480 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
4481 (return_command): Pop until the PC matches as well as the FP,
4482 so it works even if the FP is shared with another function,
4483 as in "frameless" or "leaf" procedures.
4485 * symfile.c (load_command): renamed from add_file_target_command.
4486 (add_syms_addr_command): renamed from add_file_addr_command.
4487 (add_syms_command): Stub to call target_add_syms.
4488 (_initialize_symfile): Change command names and descriptions,
4489 add-file => add-syms, and load from alias to its own command.
4491 * target.c (kill_or_be_killed, maybe_kill_then_attach,
4492 maybe_kill_then_create_inferior): Default for attempts to start
4493 a process, if one is already running, is to ask about killing
4494 it and retry if yes.
4495 (upstack_create_inferior): #if-0 it, strata obsolete it.
4496 (push_target, unpush_target, pop_target): to_close() a target
4497 before unstacking it.
4498 (target_info): Renamed from target_files_info.
4499 (_initialize_targets): Rename "i files" as "i target", accessible
4502 * target.h: Improve comments about the target_ vectored routines.
4504 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
4505 Convert commenting style to standard GNU style.
4506 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
4507 (SKIP_PROLOGUE): No longer a no-op.
4508 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
4509 (*_REGNUM): Sort register numbers.
4510 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
4511 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
4512 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
4513 are now 10 byte extendeds, not 8 byte doubles.
4514 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
4515 for nindy versus vxworks targets. FIXME, this should possibly go
4516 in the target vector.
4517 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
4518 frame_saved_regs and arg pointer with each frame.
4519 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
4520 (FRAME_ARGS_ADDRESS): Use cached result.
4521 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
4522 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
4523 (PRINT_RAMDON_SIGNAL): Call print_fault.
4524 (POP_FRAME): Now works.
4526 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
4527 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
4528 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
4529 (ADDITIONAL_OPTION_HANDLER): use target_load, not
4532 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
4533 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
4535 * valarith.c (value_subscripted_rvalue): Avoid handling
4536 floats and doubles specially; it gave alignment errors. Lint.
4538 * valops.c (value_of_variable, value_of_this): Error if unknown
4541 * valprint.c (print_floating): Bcopy rather than pointer-deref,
4542 to avoid alignment problems.
4543 (value_print): Handle unknown value address.
4544 (cplus_val_print): Two args are ignored; remove them. Change caller.
4545 (val_print): Use unpack_long rather than pointer-deref.
4548 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
4549 to avoid alignment problems.
4550 (value_being_returned): Error if return value unknown.
4551 (set_return_value): Add bogosity warning, FIXME. *
4553 * TODO: A woman's work is never done.
4555 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
4556 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
4557 Add ieee-float.o to OBS.
4558 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
4559 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
4560 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
4562 Changes to generalize the VxWorks RPC protocol slightly, to handle
4563 i960 as well as 68000.
4565 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
4566 * vx-share/reg.h: Produce i960 regs #ifdef I80960
4567 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
4568 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
4569 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
4570 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
4571 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
4572 so they will move in target byte order rather than network
4573 byte order (happens to be the same).
4575 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
4577 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
4579 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
4582 Add contribution lines to various files, showing where they
4585 * breakpoint.c (break_insn, check_break_insn_size,
4586 read_memory_nobpt): Remove to mem-break.c.
4588 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
4591 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
4592 entry has bad register number. This change is not
4593 tested in this release, FIXME.
4595 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
4598 * value.h: Force value's contents field to be aligned to hold
4599 at least a double or a long long (if supported). This avoids
4600 doing bcopy's in and out of the contents field.
4602 (step_1): Avoid coredump under obscure circumstances when we
4605 * symtab.h (misc_info): Add field to misc function vector for
4606 any kind of cached information the target code desires. AMD
4607 29000 uses this to avoid repeating examine_function_prologue's.
4609 * coffread.c: Lint. Remove static symfile, read_section_header.
4610 core.c (have_core_file_p): Lint: remove.
4611 expprint.c (print_subexp): Lint.
4612 infptrace.c, valops.c, valprint.c: lint.
4614 Roll in changes from vxgdb-5.0.1:
4616 * symtab.h: Comment byte order of each address class. Add
4617 LOC_LOCAL_ARG for frame-relative args (960).
4618 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
4619 symtab.c, symmisc.c: ditto.
4621 * infrun.c (init_wait_for_inferior): Clear stop_signal.
4623 * remote.c (remote_resume): Error if resume with a signal.
4625 * symfile.c (prim_record_misc_function): Clear misc_info.
4626 (fill_in_vptr_fieldno): Check stub type of arg.
4628 * valops.c (value_cast): Avoid looking up names of types whose
4629 name we don't know, to prevent coredump. Sun CC produces typedef
4630 rtx and the name of *rtx is zero...
4632 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4634 Roll in changes from final AMD 29000 port (Tiemann).
4636 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
4637 for ../include/a.out.encap.h. This might not work now that BFD
4638 is separately compiled. Instead, BFD support for encap will have
4639 to translate machine type 29k into the right COFF_MAGIC.
4641 * infcmd.c: Remove references to inferior_pid that aren't used
4642 in actual ptrace calls; use target_has_execution, etc.
4643 (have_inferior_p): Remove function.
4644 (program_info): Print target info rather than "process number";
4645 avoid gratuitous messages unless from_tty.
4646 (run_stack_dummy, finish_command): Set proceed_to_finish.
4647 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
4648 main.c: Lint. Lose have_inferior_p().
4649 inferior.h (have_inferior_p): Remove, lint.
4650 (proceed_to_finish): Add flag to ask that all regs be saved
4651 by normal_stop, for the few commands that need it, speeding up
4652 serial I/O. Add comments to stop_registers.
4654 * remote-eb.c: Remove newline from breakpoint message we grep
4655 for. Never time out when running the user program.
4659 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
4661 Roll in changes from vxgdb-5.0.1:
4663 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
4664 symbol in its raw form, we are processing an unlinked ".o" file.
4665 See if the target environment has assigned it an address, using
4666 target_lookup_symbol (VxWorks does), and enter it into the symtab
4669 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
4670 68k versions for a simpler version that assumes zero FP at bottom.
4671 Fixes bug of truncated stack reports.
4673 * target.h (target_lookup_symbol): Define this routine's args
4674 and result, finally.
4676 * target.c (nosymbol): Default routine for target_lookup_symbol.
4677 (target_default): Default lookup_symbol and call_function too.
4678 (files_info): Only print has_all_memory warning if a non-dummy
4681 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
4682 vx_convert_from_virtual): If target does not have floating point,
4683 zero register "values", and avoid doing cross-net conversions.
4684 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
4685 (vx_open): Rearrange code that attaches to target and reads
4686 symbols for all loaded modules, to work if some of the modules
4687 are not accessible. Add symbol_stub() and add_symbol_stub()
4688 as callbacks from catch_errors(). Allow connect attempt to be
4689 interrupted painlessly with ^C (FIXME, there are still some bugs
4690 if the interrupt happens during symbol reading.). Print
4691 final message with puts_filtered, since symbol messages are
4696 * main.c (catch_errors): Only print errstring if non-null.
4697 (command_loop): Avoid an ioctl per command to test ISATTY.
4699 * remote-vx.c (net_load): make static; avoid sophomoric msg.
4700 (vx_xfer_memory): Return correct result!
4701 (vx_files_info): Indicate whether target has float or not.
4702 (vx_lookup_symbol): Complain, not error, if target gone.
4703 (vx_open): Print "Connected" msg before disabling immediate-quit.
4704 [FIXME: lookup_symbol and vx_open changes need testing.]
4706 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
4707 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
4708 contributor lines and update copyrights to 1991.
4710 Changes from an attempted H-PUX host port:
4712 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
4713 defines PT_ATTACH and PT_DETACH but not PT_KILL.
4714 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
4715 * remote-vx.c: include <sys/time.h> for HPUX.
4716 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
4717 "core_file_command" routine to BFD regime. May not work yet.
4719 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
4721 * xgdb.c: Replace X10 version with some VJ version.
4722 (FIXME: Its copyright assignment is not on record.)
4723 * xgdb.c: Update include files to X11R4 (Xaw crud).
4724 (xgdb_display_source, create_text_widget): fix call to
4725 get_filename_and_charpos. Rewack source window stuff for X11R4
4726 (gleaned from include files, and "nm's" of binary libraries, since
4727 I had no doc available).
4728 (append_selection, append_selection_word): Disable with FIXME
4729 since R4 changed interface here.
4730 (create_buttons): Add back the old set of buttons.
4731 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
4733 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
4734 Roll VERSION to 3.94 (not yet final though).
4736 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4738 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
4739 obstack_int_grow, obstack_int_grow_fast): Eliminate
4740 cast on left of assignment, which gives MIPS cc fits and is
4743 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
4744 F_ALIAS. Use printf, not fprintf, when not passing a file
4746 (compare_opcodes): Check that identical instructions have
4747 identical opcodes, complain otherwise.
4749 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
4750 was reported by Roland McGrath.
4751 (unimp): Only match if exactly zero instruction. (Roland)
4752 (branches and traps): Generate all variations of these
4753 instructions with macros, based on a single call that defines
4754 each condition name and its binary representation.
4755 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
4757 * valprint.c (val_print_fields): Take, and use, format parameter.
4758 This means that "p/x struct" again prints the elements in the
4759 desired format. Changed callers.
4761 * stack.c (frame_info): Use filtered output, and indicate wrap
4762 points. Remove kludgy formatting designed to avoid line wrap.
4764 * utils.c (wrap_here): If the line is already full (because
4765 we had printed a long indent or long wrapped string), do an
4766 immediate newline-and-indent.
4768 * m68k-pinsn.c (print_insn_arg): Bugfix from
4769 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
4770 instruction is incorrectly disassembled as bkpt #8.
4772 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
4773 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
4774 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
4775 and then will dump core (sometimes). I traced it back to an
4776 uninitialized symfile_name in psymtab_to_symtab.
4777 (const_vol_complaint): Add quotes to message.
4778 (define_symbol): Only believe line number if gcc_compiled.
4779 Avoid allocating symbol if we will not return it.
4781 Add target strata support so that newly established targets go
4782 into their right place in the target stack (e.g. a new exec file
4783 doesn't wipe out the ability to access the running process).
4785 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
4786 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
4787 and initialize it properly in all the targets.
4789 * target.h: Document strata. Change return type of push_target.
4791 * target.c (nomemory): new function for dummy memory access.
4792 (tcomplain): Rename complain, now also used in symfile.c.
4793 (push_target): Push targets within strata. New return value shows
4794 whether new target is on top of stack or not. Always keep dummy
4796 (target_files_info): Ignore dummy target.
4798 * core.c (core_open): Warn user, and skip accessing file, if the
4799 core target is not the topmost target in the stack.
4800 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
4803 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
4804 target_ops, it doesn't belong there since we have no regs there.
4805 Change name of target from machine => memory to clarify.
4807 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
4809 * Freeze version 3.93 for release.
4811 * Makefile.dist: Handle vx-share and nindy-share subdirs
4812 properly when building gdb.tar.Z.
4814 * symtab.c: lint; add no_symtab_msg to consolidate the messages
4815 printed in various places, so I could change just one copy.
4817 * dbxread.c, coffread.c: Change references to bfd->iostream
4818 to cast to FILE *, now that BFD avoids needing types defined
4819 in other header files.
4821 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
4823 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
4824 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
4825 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
4826 (actually gcc -Wall).
4828 * dbxread.c: Remove first_global_sym, last_global_sym, since
4829 they are never referenced.
4831 * defs.h (baud_rate): Declare.
4832 main.c: Define it, and add the -b option to set it.
4834 * gdb-int.texinfo: Add text on how to define a new host or target
4835 architecture, prompted by Per Bothner's questions about MIPS
4838 * gdb.texinfo: Document "complaints". Change doc of -q since
4839 gdb no longer prints the copyright and blurb if you specify a file
4840 name to be debugged (just like Emacs). Add doc for Nindy-specific
4841 command line flags for specifying target serial port and such.
4842 Update copyright to 1991.
4844 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
4845 has taken over for us the job of ripping up executable files. The
4846 crud caused Per Bothner's port to not compile.
4848 * infrun.c (normal_stop): Avoid printing "Program exited
4849 normally" if we are in batch mode. This allows a GDB which
4850 executes a program on a target system, to behave like a Unix
4851 command (input from stdin, output to stdout, no extraneous
4854 * main.c (main): Allow additional machine-dependent command line
4855 options to be specified with the ADDITIONAL_OPTIONS,
4856 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
4857 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
4858 processing to occur just before the main loop with
4859 BEFORE_MAIN_LOOP_HOOK.
4860 (main): If a "core file" argument is specified, and it is not a
4861 core file, try it as a process ID to attach.
4862 (symbol_completion_function): Attempt to cope with
4863 "show screen-" TAB, not very successfully. This needs more work,
4865 (batch_file): New function, returns whether we are reading
4866 commands from an interactive tty on stdin, or from somewhere else.
4867 Called by normal_stop since it doesn't get from_tty passed down
4868 to it like many commands do.
4870 * remote-nindy.c: Handle command line options for nindy
4872 (nindy_before_main_loop): Prompt user for tty name if they
4873 don't specify it before getting to the interactive command loop.
4875 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
4876 and -r command line options. Also add hook before main loop
4877 to make it easy to specify a tty.
4879 * TODO: More things to do, one done.
4881 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
4883 * dbxread.c: Make complaint() calls pass pointer, not struct.
4884 Add complaints about badly formatted C++ type information
4885 (const/volatile indicator, and parse errors resulting in
4886 error_type). Fix C++ virtual member fn comment.
4887 (read_struct_type): Avoid bumping pointer if we got a parse
4888 error; this prevents our walking beyond the end of a string.
4889 Terminate loop on null char as well as semicolon.
4890 (process_one_symbol): Fix the LBRAC fix so that it uses the
4891 last previous SLINE, FUN, or SO record's PC address. C++ debug
4892 symbols did not have SLINE records in a useful order compared
4893 to the LBRAC records.
4894 (define_symbol): Handle "catch" records.
4896 * symtab.c (check_stub_type): Added new complain
4897 `stub_noname_complain' and added a consistency check to
4898 keep the debugger from crashing when finishing from an
4899 exception frame. A real fix will be needed later.
4901 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
4903 * infcmd.c (attach_command): Make global.
4905 * Makefile.dist (REMOTE_OBS): Make these compile by default,
4906 but make them easy to comment out. Perhaps later they should
4907 be enabled by what CPU you configure for? FIXME.
4908 (VERSION): Roll to 3.93.
4909 (pinsn.o): Remove rule for obsolete file.
4910 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
4912 Run down a problem that manifested by printing the wrong function
4913 name in stack traces of read_ofile_symtab. Turned out that the
4914 problem was the SunOS 4.1.1 (and previous) C compiler outputs
4915 the LBRAC symbol with an address in the *data* segment, which
4916 blew our binary search through the blocks.
4918 * dbxread.c: Use the complain() facility consistently to bitch
4919 about problems in the symbol file we are reading.
4920 (finish_block): Add code to check the nesting of the blocks;
4921 complain and Procrust them to fit if wrong.
4922 (make_blockvector): Check the order of the blocks, complain
4923 [but don't cope] if wrong.
4924 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
4925 symbols to be sure their PC value is greater than the last SLINE
4926 (line number) symbol we've seen, complaining and adopting the
4927 SLINE PC value if wrong.
4929 * symfile.h (struct complaint, complaint_root, complain,
4930 clear_complaints): Add.
4931 * symfile.c (complain, complaint_root, clear_complaints): Add
4932 facility to deal with non-fatal complaints and to regularize their
4934 (symbol_file_add): Clear complaint counters to allow new complaints.
4935 (initialize_symfile): Add 'set complaints' and 'show complaints'.
4937 * dbxread.c (dbx_symfile_read): Remember the address and size
4938 of the string table for the main symbol file, so we won't read it
4940 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
4941 to avoid reading the string table yet again. Lint.
4942 (throughout): Improve filtered output, including word wrap.
4943 (read_range_type): Improve Bothner's fix to handle other types too.
4945 * utils.c: Improve line wrap implementation. Handle unlimited
4946 width by making chars_per_line unsigned.
4947 (puts_filtered): New, easy, function.
4949 * defs.h (puts_filtered): add.
4951 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
4952 call the identical sort_symtab_syms() in symfile.c instead.
4954 * expread.y: Suggest the `file' command rather than `symbol-file'.
4956 * command.h (enum var_types): Add zinteger for seroable
4958 * command.c (do_setshow_command): Handle var_zinteger. Restructure
4959 nested if's into a switch.
4961 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
4962 we did not stop because of a breakpoint (it must have been for
4963 some other reason, like a "stepi"), so don't print anything.
4965 * symtab.c: Include <sys/types.h> all the time. Now that BFD
4966 doesn't include <sys/types.h>, old SunOS's require it for
4969 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
4971 A test port of gdb-3.92.6 to the Sony NEWS.
4974 Don't normally link in remote- or vx stuff.
4975 Some of it doesn't compile, and it wastes space for 99% of the users.
4976 Remove reference to no-longer-used HAVE_VPRINTF.
4977 Fixed BFD_DEP typo to BFD_DIR.
4979 Fix cast in arg to bfd_h_getlong.
4980 Make char *prefix be const.
4981 Fix how certain range types are mapped into builtin unsigned int types.
4983 Remove 2 #includes. They cause errors (on Sony, at least),
4984 and aren't needed (they wern't in earlier versions).
4986 print_address_symbolic should never demangle labels
4987 (since it prints *assembler-level* labels).
4989 [This was superseded by the change to printcmd below.]
4992 Add some "volatile" return types to avoid warnings.
4993 If MISSING_VPRINTF add vprintf function and not just macro
4994 (since vprintf is used in printcmd.c).
4996 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
4997 (The latter isn't grokked by some PCC-based compilers.)
4999 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
5001 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
5002 * nindy-share/coffstrip.c
5003 Added some forward declarations (otherwise, gcc complains
5004 about implicit extern redefined as static).
5006 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
5008 Changes inspired by Per Bothner:
5009 * printcmd.c (print_address_symbolic): Take additional parameter
5010 specifying whether to demangle.
5011 (print_address): Pass in asm_demangle to control demangling.
5012 (print_address_demangle): New fn, takes explicit arg to control
5014 * utils.c: Add new vars demangle and asm_demangle, and let them
5016 (fputs_demangled): If !demangle, just print the argument.
5017 (fprint_symbol): If !demangle, just print raw symbol.
5018 * valprint.c (val_print): Call print_address_demangle rather than
5019 print_address, to cause demangling to depend on the global
5020 rather than assembler-level demangling setting.
5021 * WHATS.NEW, gdb.texinfo: Document.
5023 * main.c (show_command): Show all settings if no arg.
5024 (initialize_main): Make "info set" the same as naked "show".
5025 * command.c (cmd_show_list): Handle prefix commands in the
5026 list, and print the name of the setting as well as its English
5027 description and value.
5029 Allow gdb functions to specify where a line should wrap if it
5030 exceeds the size of a terminal line. Use it to make the output
5032 * utils.c (set_screen_width_command): New fn, mallocs a buffer
5033 of the right size when screen width changes.
5034 (set_screensize_command, screensize_info): Remove #if 0'd fns.
5035 (wrap_here): New fn, indicates a point in the output where we
5036 should wrap the line rather than just letting it overflow at a
5038 (fputs_filtered): Implement wrapping.
5039 (n_spaces): New fn, returns a pointer to N spaces.
5040 (print_spaces_filtered): Use n_spaces.
5041 * defs.h (n_spaces): Declare.
5042 * stack.c (print_frame_info): Wrap with 4-space indent after
5043 fn name and before filename and line number.
5044 * printcmd.c (print_frame_args): Wrap with 4-space indent
5045 before each argument name is printed.
5046 * valprint.c (value_print): Wrap with no indentation before
5048 (val_print_fields): Wrap with indentation relative to nesting
5049 level before each field name.
5050 (val_print): Wrap with nesting indentation before array elements.
5051 * command.c (do_setshow_command): Avoid extra newlines,
5052 wrap with 4-space indent around values printed, end with period.
5053 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
5055 * breakpoint.c (breakpoint_1): Implement addressprint for
5056 "info breakpoints" display. Change file name and line number
5057 format to " at file:nnn" rather than " (file line nnn)".
5058 * gdb.texinfo: Document.
5061 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
5063 Frozen for gdb-3.92.6 release.
5065 README, WHATS.NEW: Update for 3.92.6 release.
5067 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
5068 coffread.o from configs since it is now built by default.
5069 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
5070 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
5071 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
5072 from configs since it is now built by default.
5074 Makefile.dist: Update for release 3.92.6. Handle files that
5075 have been moved to ../include, ../getopt, or ../bfd. Add
5076 saber.suppress and tests directory. Add config.status to
5077 the release (it will say "none").
5079 coredep.c: Minor formatting fixes.
5081 These changes were made in early December but only checked in now:
5082 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
5083 nindy-share/nindy.c: lint
5084 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
5085 register values coming back from the target; we store values
5086 in target byte order everywhere.
5088 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
5090 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
5092 * valprint.c (cplus_val_print, val_print_fields): New functions,
5093 which print C++ objects. They conspire to avoid printing a
5094 virtual base class more than once, following all the twists and
5095 turns of C++ virtual base rules.
5096 (val_print): Call the above rather than do it by hand.
5098 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
5099 symbol file, not for added files like shared libs. This really
5100 needs to be generalized to a timestamp per file.
5102 * core.c (cleanup_core): Avoid coredump if no core file.
5104 * config.gdb: Accept -host or -target in place of +host or
5107 * coffread.c (find_linenos): Avoid desupported BFD interface
5108 to line numbers. We still read them manually rather than using
5109 BFD's "generic" features.
5111 * gdbrc.tex, threecol.tex: Add GDB reference card and its
5113 Makefile.dist: Add refcard to OTHERS list for creating tar files.
5115 * Makefile.dist: Eliminate use of $< in explicit targets.
5117 * readline/Makefile: Use $< rather than $*.c, which does not
5118 include the VPATH in GNU Make.
5120 * tconfig/i960-bout, tconfig/i960-coff: These are identical
5121 copies of tconfig/i960, added for global configuration
5122 compatability. All i960 versions can read both coff and b.out.
5124 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
5125 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
5128 * TODO: Think of more things to do.
5130 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
5132 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
5133 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
5134 64-bit float conversion.
5136 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
5137 equivalent to sun?os4 so global config works.
5139 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
5141 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
5143 * main.c: Only declare linesize once; declare pagesize not at
5144 all, since it is never used.
5145 (main): Clear newly allocated line before it is used.
5147 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
5149 Further stabilization for the Intel 960.
5151 * Makefile.dist: Parameterize the location of the "include"
5152 and "bfd" directories, as well as "getopt". Add symfile.c.
5153 Link in both dbxread and coffread. Fix up "make depend" to
5154 rewack the locations of include, bfd, and getopt in its output.
5156 * README: Document moving include files, improve some of
5159 * coffread.c: Move common code out to symfile.c. Change
5160 symbol_file_command style interface to use new *_symfile_init
5161 and *_symfile_read interface under BFD. Use BFD internal
5162 info to locate line table, symbols, etc.
5164 * core.c (core_fetch_registers): Rename to get_core_registers
5165 to avoid confusion with fetch_core_registers.
5166 (register_addr): Move to coredep.c, which is already machine
5167 dependent. This leaves core.c pretty clean of dependencies.
5169 * coredep.c (register_addr): Accept this routine from core.c.
5171 * dbxread.c: Move common code (with coffread.c, etc) into new
5172 symfile.c. Each psymtab now contains a pointer to the
5173 format-dependent function that knows how to read it in. Make
5175 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
5176 (process_one_symbol): Add code to complain about a "compiler bug
5177 we muzzle here", if we actually see it.
5179 * eval.c (evaluate_subexp): Insert missing "break" statements
5180 in code that determines whether a variable is an lvalue in
5181 memory, register, or whatever. I detected this via a compiler
5182 bug in which it *almost* mashed out the whole switch statement.
5184 * gdb-int.texinfo: Add minor sections on configuring gdb for
5185 release, and about the README file.
5187 * infcmd.c (registers_info): Fix formatting somewhat. Still
5188 not as pretty as before, but it handles byte swapping.
5190 * remote-nindy.c: If data cache routines are interrupted while
5191 waiting for the remote end, be sure that any uninitialized cache
5192 blocks are on the free list, not on the valid list!
5194 * symfile.h: Flesh out this header file with all the various
5195 routines and variables that have been merged in from dbxread.c
5196 coffread.c, and symtab.c to symfile.c.
5198 * symfile.c: New file, containing code common to dbxread.c,
5199 coffread.c, and some code from symtab.c. All generic code for
5200 reading symbol files should be in here now.
5201 (unrecord_misc_function): Remove unused function.
5203 * symtab.h: Remove file-reading things to symfile.h.
5205 * symtab.c: Remove file-reading things to symfile.c.
5207 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
5208 to decode i960 fault types.
5210 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
5211 target.c: Change type of the "resume" function from int to void,
5212 since its result was never used.
5214 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
5216 * main.c: Replace "stupid" with "caution"; you now "set caution
5219 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
5221 * infcmd.c (do_registers_info): Call val_print to deal with the
5222 byte order of the registers being printed. FIXME, this makes
5223 the formatting of the output uglier.
5225 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
5226 defined, call it for signals the debugger doesn't itself use.
5227 The i960 uses this for more detailed fault information.
5229 * remote.c (remote_open): If arg is null, print help rather than
5232 * sparc-xdep.c (register_valid): Avoid declaring size, since
5233 various modules will think of various sizes depending on the
5234 architecture of their tm-file. FIXME, we need protection against
5235 actually entering one of those modules, which would clobber
5236 storage if not for the target architecture compiled into gdb.
5238 * stack.c (up_command, down_command): Always print the frame
5240 (up_silently_command, down_silently_command): New commands
5243 * i960-pinsn.c (reg), i960-tdep.c: Lint.
5245 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
5246 more parameters than it used to.
5248 * findvar.c (registers): Increase slop to 256 bytes, which should
5249 protect us against even most RISC machines with large register
5251 (locate_var_value): Move declaration inside related ifdef.
5253 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
5254 throughout, to avoid throwing away buffered input from the board.
5255 (nindy_wait): Supply_register takes addr_of_value, not value.
5256 (i960_print_fault): Renamed from i80960_fault.
5257 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
5258 (nindy_store_registers): Avoid regs_changed stuff, just stuff
5260 (nindy_create_inferior): Don't bother to write PC_REGNUM since
5261 we can set the PC in the call to proceed(). Unpush nindy_ops
5262 before pushing it on top, to avoid message to user. Eliminate
5263 commentary from Unix machines that just misleads here.
5264 (reset_command): Fix error message to suggest target command.
5266 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
5268 Release 3.92.5 as frozen.
5270 Stabilize the merged release...with help from lint, Saber C,
5273 Everywhere: Add include files needed to declare return types
5274 of functions called.
5276 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
5278 * breakpoint.h: Add undeclared breakpoint functions, and some
5279 functions for display handling since I couldn't think of a better
5282 * breakpoint.c (insert_breakpoints): Make code for disabling
5283 shared library bkpts more likely to work. It's used when we
5284 rerun a program and stop before the shared library has been
5286 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
5287 cast from pointer, so it squeezes through catch_errors.
5288 (bpstat_stop_status): Fix logic broken some time ago. We now
5289 always create a bpstat if the stop address matches a breakpoint,
5290 even if we don't stop there -- just like the old code used to do
5291 before I got my fingers into it (sigh).
5292 (breakpoint_1): Print "ignore count" after "stop only if"
5293 condition, since that's how it actually works.
5294 (mention): Handle watchpoints as well as breakpoints.
5295 (watch_command): use set_raw_breakpoint and mention to do most
5296 of the work (and initialize all the fields!). Only pass one
5297 arg to parse_c_expression, since that's all it takes.
5299 * command.c (not_just_help_class_command): Rename arg to args
5300 since we ignore "unused argument" warnings on vars named "args".
5301 inflow.c (child_terminal_info): ditto.
5302 infptrace.c (kill_inferior): ditto
5303 main.c (catch_errors, version_info, quit_command, pwd_command,
5304 source_command, dump_me_command, editing_info,
5305 set_history_size_command, set_history, show_history,
5307 stack.c (locals_info): ditto
5308 target.c (target_files_info): ditto
5309 valprint.c (set_input_radix, set_output_radix): ditto
5311 * core.c: Remove old variables for handling core and exec file
5312 sections (data_start, data_end, stack_start, stack_end,
5313 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
5314 text_end, exec_data_start, exec_data_end, text_offset,
5315 exec_data_offset, data_offset, stack_offset). They're
5316 superseded the more general build_section_table and
5318 (get_exec_file): Mention the `file' command.
5319 (read_memory_check): Rename to memory_error, and only call it
5320 in the case of an actual error.
5321 (read_memory, write_memory): call memory_error.
5322 (core_fetch_registers): Register section name is ".reg".
5324 coredep.c: Remove a bunch of crud now that all this file does
5325 is pull the registers out of a core file.
5326 (fetch_core_registers): Rewrite to actually work, I hope.
5328 dbxread.c: Use a.out.gnu.h, not system a.out, now.
5329 Replace index() with strchr(). Remove all the pre-BFD macro
5330 definitions for accessing the symbol file.
5331 (struct dbx_symfile_info): Encapsulate the information that
5332 dbx_symfile_init needs to pass to dbx_symfile_read in this
5335 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
5336 dbx_symfile_discard): Rearrange symbol file reading to divide
5337 the format-specific part from the format-independent part,
5338 leaving the format-independent part such as file name expansion
5339 and opening in symtab.c. This replaces
5340 partial_symbol_file_open and partial_symbol_file_read.
5341 Symbol_file_read, add_file, add_file_target_command,
5342 add_file_addr_command move to symtab.c. Pass an explicit
5343 "mainline" flag for when reading the main symbol table, rather
5344 than relying on the offset address to be zero or nonzero.
5346 (dbx_symfile_read): Don't allow void *'s to be printed as
5348 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
5349 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
5350 macro" debug version really work.
5351 (read_dbx_symtab): Remove unref'd parameter inclink.
5352 Avoid swapping N_SLINE symbols, for speed.
5353 Merge N_TEXT!N_EXT case with the other external symbol
5354 definitions' case. Add comments.
5355 (start_psymtab): Allocate the symfile name in the psymtab on
5356 the psymbol_obstack, rather than using the caller's storage.
5357 (end_psymtab): Only allocate a dependencies list if there are
5359 (psymtab_to_symtab_2): Use BFD when reopening file to read
5360 its symbols for real.
5361 (read_struct_type): Add FIXME comments where it needs work
5363 (read_huge_number): Add FIXME about overflows.
5364 (read_range_type): Add FIXME about comparing a long to 1<<32.
5366 * coffread.c: Minor changes to move things closer to the new
5367 regime with symtab.c and dbxread.c Major work is still needed
5370 * exec.c (exec_file_command): Remove old variables (see core.c
5372 (xfer_memory): If memory transfer is right at the end of a
5373 section, don't lose.
5375 * findvar.c (get_saved_register): If value is in a real
5376 register, LVAL is lval_register, not lval_memory.
5378 frame.h: Declare print_sel_frame and record_selected_frame.
5380 gdb-int.texinfo: New file, for GDB internals documentation.
5381 Very simple, unformatted doc of cleanups is there for now.
5383 gdbcore.h: Remove obsolete variables that described a.out
5384 section addresses and offsets. (See core.c above.)
5385 Declare fetch_core_registers and registers_fetched.
5387 getopt.c: Declare char *alloca(); even on SPARC.
5389 infcmd.c (run_command): Call target_kill rather than
5391 (step_command, next_command, stepi_command, nexti_command):
5392 Declare from_tty parameter even though we don't use it.
5393 (run_stack_dummy): argument BUFFER is a char array, not
5394 a pointer to REGISTER_TYPE.
5395 (finish_command): using_struct_return needed a value *,
5396 not a struct symbol *.
5398 * infptrace.c (child_xfer_memory): To avoid dependency on
5399 where sections are in memory, try PT_WRITE_D and if that fails,
5400 try PT_WRITE_I. Most Unixes don't care which you use.
5402 * infrun.c (step_resume_break_shadow): Change to array to
5403 match other breakpoint shadow storage.
5404 (clear_proceed_status): Pass address of bpstat to
5405 bpstat_clear, not the bpstat itself.
5406 (child_create_inferior): FIXME comment about if the child
5408 (start_inferior): Remove old function.
5409 (child_open): Use target_kill rather than kill_inferior.
5410 (wait_for_inferior): Ditto.
5411 (insert_step_breakpoint, remote_step_breakpoint): Use
5412 new step_resume_break_shadow.
5414 * inftarg.c (child_wait): If all child processes die,
5415 pretend that the one being waited for exited with signal 42.
5417 * main.c (command_line_input): When scanning for comments,
5418 don't coredump on unclosed quotes.
5419 (quit_command): Use target_kill rther than kill_inferior.
5420 (_initialize_main): Rename class_user from "user" to
5423 * printcmd.c (print_command_1): Initialize "fmt" if no format
5424 is specified by the user.
5425 (print_frame_args): Only add to args_printed if we are
5426 actually fetching args from the stack (avoiding undefined
5428 (_initialize_printcmd): Remove bogus \{ from string.
5430 * remote-eb.c (eb_open): Avoid coredump on no argument.
5432 * remote-nindy.c: Bring out of Intel environment into new
5433 target environment. Remove all conditional compilation on
5434 I80960. Massive hacking throughout.
5435 (nindy_xfer_inferior_memory): New routine stolen from
5437 (nindy_create_inferior): New routine pieced together, probably
5438 not quite working yet.
5439 (nindy_ops): New target_ops struct for nindy.
5441 * remote-vx.c: Use write_memory rather than target_write_memory
5442 to get error checking.
5443 (vx_add_file_command, vx_open): Use symbol_file_add rather than
5445 (vx_create_inferior): Use target_terminal_ours...
5447 * signame.c (_initialize_signame): Always initialize, since
5448 we need the table for things other than psignal.
5450 * solib.c (solib_add): Use symbol_file_add, not add_file.
5451 (solib_address): Return boolean result rather than struct
5452 pointer which nobody else knows the type of.
5454 * sparc-tdep.c, valops.c: Use write_memory rather than
5455 target_write_memory, to get error checking.
5457 * stack.c (locals_info, catch_info, args_info,
5458 get_selected_block, frame_command, up_command): Use
5459 target_has_stack, rather than have_inferior_p or
5462 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
5464 * symfile.h: New file, defining the interface between the
5465 generic and object-file-specific symbol reading code.
5467 * symtab.c: Move generic symbol-reading interface to symtab.c,
5468 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
5469 table to map BFD targets to symbol-reading modules in GDB.
5470 Change index to strchr.
5471 (lookup_struct_elt_type): Use error() rather than hand-made
5472 simulations thereof.
5473 (lookup_partial_symbol): Speedup slightly when length == 0.
5474 (symbol_file_add): New function.
5475 (symbol_file_command): Call it.
5476 (symfile_open, symfile_init): New function.
5477 (add_file_target_command, add_file_addr_command): moved from
5480 * target.c (target_command): use target_kill.
5482 * target.h (target_files_info): Don't declare, never called
5485 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
5486 files to determine stack end address.
5488 * valarith.c (value_x_binop, value_x_unop): Change error message
5489 to be more useful. Pass proper argument to value_struct_elt.
5491 * valops.c (value_assign): FIXME comment that long long
5492 bitfields will break here.
5494 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
5495 Update `make saber_gdb' to work better.
5497 * TODO: A woman's work is never done.
5499 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
5500 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
5501 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
5502 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
5503 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
5504 valops.c, valprint.c, exec.c: Lint.
5507 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
5509 Continuing Intel 960 port merge of GDB.
5511 * Makefile.dist: Merge i960 "nindy-share" files. Rename
5512 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
5513 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
5514 Wack over "make depend" so it handles files in subdirectories
5515 vx-share, nindy-share, bfd, and in the current directory.
5517 * blockframe.c (get_prev_frame_info): Remove fatal error
5518 if stack not defined.
5520 * core.c (core_open, core_detach): New functions that handle
5521 the old "core-file" command as "target core" and "detach" instead.
5522 (core_file_command): Call them.
5523 (core_xfer_memory): Use common routine xfer_memory.
5525 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
5526 dbxread now uses bfd for everything but symbol reading itself.
5527 BFD internals are used to drag out the relevant file offsets.
5528 (partial_symbol_file_open): Change args all around for BFD.
5530 * symtab.c: Rename "value" to "val" everywhere, so we can
5532 (symbol_file_command): New command, moved from dbxread.c
5533 and coffread.c. It uses BFD to read the file, then vectors
5534 based on its type, to dbx or coff symbol readers.
5535 * symtab.h: Extern a few vars for symbol_file_command.
5537 * target.h: Breakpoint takes a char * save area, not a char **.
5539 * valprint.c (val_print): When unpacking bitfields, offset
5540 the address in gdb of the value, if it is declared with a shorter
5541 type. Remove the last "runtime kludge test" of host byte order.
5543 * utils.c: Remove old my_bfd_read routine.
5545 * stack.c (frame_info): Use target_has_stack. Print program counter
5546 register's actual name rather than "pc", since it's called the
5547 "ip" (instruction pointer) on the i960 (sigh).
5549 * target.c (target_command): Add command for selecting a target
5550 type and calling its open routine. This is used for initiating
5551 communication with a particular target, in a generic way.
5553 * tm-i960.h: Update for modern gdb. Remove semicolons from
5554 various macros. Handle reading struct return convention, and
5555 error-out attempts to return structs with the "return" command.
5556 Be sure gdb doesn't think we know how to call functions in the
5559 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
5560 to i960_xxx in lower case.
5561 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
5562 not being defined yet.
5564 * remote.c (remote_open): Call start_remote to initialize
5565 wait_for_inferior during open.
5566 (remote_xfer_inferior_memory): Return length written rather
5569 * remote-vx.c (target_command -> vx_open): Use new generic
5571 * remote-eb.c, inftarg.c, exec.c: ditto.
5573 * infrun.c: Fix comments.
5574 (attach_program -> child_open): Use new generic target command.
5575 (wait_for_inferior): Clear saved register values before target_wait,
5576 so target_wait can set some of them if convenient.
5578 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
5579 Return success indicator, not void.
5580 (child_xfer_memory): Avoid fetching initial word if we'll
5581 overwrite it anyway.
5583 * infcmd.c (attach_command): Use new generic target open routine.
5584 (_initialize_infcmd): Update doc on attach and detach commands.
5585 (do_registers_info): Merge in a byte-order problem as a FIXME
5588 * findvar.c (find_saved_register): Avoid problem in current frame.
5589 (read_relative_register): Ditto.
5590 (write_register): Convert byte order on the way out.
5592 * exec.c (file_command): Add.
5593 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
5594 (xfer_memory): Common function between core_xfer_memory and
5596 (exec_xfer_memory): Use it.
5598 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
5600 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
5601 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
5602 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
5604 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
5606 Merge Intel 960 port of gdb, continuing...
5608 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
5609 symbol_file_command): Pass from_tty arg to hush 'em up.
5611 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
5612 Add magic numbers for 960 COFF format.
5614 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
5616 Merge Intel 960 port of gdb, from Intel "1.2" release.
5618 CHANGE_LOG entries from their port, which was based on

5622 Remove temp file if download is interrupted.
5624 Wed Aug 1 09:08:33 PDT 1990
5625 Now uses binary protocol to talk to NINDY.

5627 Times out after 5 seconds when trying to talk to NINDY.
5629 Tue May 29 12:54:49 PDT 1990
5630 Added variable baud rate (-b switch).
5631 Source code reorganization.
5633 Thu Apr 26 11:09:55 PDT 1990
5634 More cleanup of batch mode; specifically, execute "-s", "-e", and
5635 "-se" switches as soon as they are encountered on the invocation line.
5637 Fri Apr 20 13:47:15 PDT 1990
5640 Thu Apr 19 09:54:28 PDT 1990
5641 Add 'reset' command.
5643 Wed Apr 18 09:48:07 PDT 1990
5644 After opening remote tty, wait for 1 second to go by without input
5645 from it before trying to talk to NINDY (fixes problems with the
5646 Heurikon HK80/V960E).
5648 Mon Apr 4 16:33:05 PDT 1990
5649 Some output was not being suppressed in 'batch' mode.
5651 Thu Mar 22 15:31:11 PST 1990
5652 Ask user if old symbol table should be deleted when new file is
5655 Allow user to run a program downloaded before gdb960 was brought up.
5657 Correct "exec-file" help message for i80960 context.
5659 Correct bug in calculating user space address: could occasionally
5660 corrupt user program.
5662 Make sure to zero low-order bits in rip's because of bug in 960CA
5663 A-step part: could cause operation faults when "next"ing across
5666 Correct bug that made it impossible to get source line numbers for
5667 code loaded at addresses higher than 0x7fffffff.
5669 Wed Jan 10 12:43:22 PST 1990
5670 Open remote tty for exclusive use.
5672 Fri Jan 5 12:14:42 PST 1990
5673 Correct disassembly (CA manual was right after all):
5674 opcode for sysctl is 0x659
5676 Mon Oct 23 12:03:04 PDT 1989
5677 Use G960BASE and G960BIN environment variables to find 'sx' utility.
5679 Mon Oct 16 14:15:09 PDT 1989
5680 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
5682 Mon Oct 2 15:56:31 PDT 1989
5684 Added 960CA disassembly support.
5686 To simplify maintenance:
5687 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
5689 - eliminated opcode.h: incorporates tables into i960-pinsn.c
5690 - moved 960-specific routines from i960-pinsn.c to i960-md.c
5691 - made disassembly interface identical to that in gdmp960.
5695 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
5697 * target.h: Allow targets to stack. Add target_has_memory,
5698 _registers, etc. Restructure memory access and "info files"
5699 to walk the target stack.
5700 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
5701 target.c: Change tables to match target.h.

5707 * remote-vx.c: New memory regime, new info files. Now use
5708 separate targets for VxWorks attachment to machine, and
5709 actually running a process under VxWorks, since one has
5710 stack & execution & regs and the other doesn't.
5711 * remote.c: New memory regime, new info files.
5712 * sparc-xdep.c (fetch_core-registers): New memory regime.
5713 * target.c: New routines and support for stacked targets,

5756 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
5758 Massive changes to wall off the remote-debugging interface
5759 behind a function vector. The port to handle VxWorks targets
5760 is also part of this.
5762 All files: Replace references to renamed functions,
5763 remove references to remote_debugging, remove references to
5764 have_include_file, have_core_file in favor of target_has_stack,
5765 target_has_memory, etc.
5767 * Modularize the breakpoint interface.
5768 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
5769 a breakpoint instruction.

5776 the single-step breakpoints.
5777 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
5778 New file, contains routines to insert and remove breakpoints by
5779 reading out the old contents and later replacing them. This is
5780 how ptrace breakpoints work, and many remote systems as well.
5782 * tm-vxworks68.h: New config file, overrides a few things for
5783 Wind River's preferences.
5785 * target.h: New file, for transfer vector used to talk to the
5786 inferior (child, attached, core, exec, remote, etc). All accesses
5787 to the thing being debugged should come through these vectors.
5788 target.c: New file, routines to handle transfer vector.
5789 (various files): Add transfer vectors XXX_ops for the various
5790 targets and pseudo-targets (core files, etc) we support.
5792 * breakpoint.c (bpstat_stop_status): Further explorations of
5793 watchpoints and why things don't work all the time.
5794 (bpstat_alloc): New fn to allocate a bpstat and chain it.
5796 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
5797 the local gdbinit if it doesn't already have it.

5800 Allow core debugging without exec file.
5802 * dbxread.c (free_and_init_header_files): Merge two fns.
5803 (end_symtab): Free named symbol table when a new version comes in.
5804 (read_dbx_symtab): Relocate all kinds of symbols with base
5805 address. First step toward handling different text, data, bss
5807 (add_file_addr_command): Renamed add_file_command.
5808 (add_file_command): Vector to remote handler.
5809 Add "load" as an alias for "add-file" command.
5811 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
5812 non-returning functions.
5814 * exec.c: Add exec_ops, and push it as a target when an exec
5817 * infcmd.c (run_command): Pass executable file name and arg list
5818 separately when starting an inferior. Permit "run" when no exec
5819 file is specified, for VxWorks.
5820 (detach_command): Move to child_detach in inftarg.c.
5822 * inftarg.c: New file. Unix-child-specific routines, and the
5823 child_ops structure.
5825 * inferior.h (registers): Export "registers" as the way for
5826 target dependent register handlers to find gdb's local copy of
5827 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
5828 since it is now used by places that want wait_for_inferior to
5829 handle the grunge but want to see every trap from the inferior.
5831 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
5832 Eliminate remote_debugging hooks in terminal handling.
5834 * infrun.c: Replace start_inferior with child_create_inferior.
5835 Move all the hair of Unix shells and ptrace idiosyncracies into
5836 child_create_inferior, so remote handlers don't have to deal.
5837 Remove running_in_shell. Rename stop_after_attach to
5838 stop_soon_quietly, and use it in a few other places where we want
5839 to just call wait_for_inferior and get control back on the first
5840 trap. trap_expected now never takes a value > 1.
5841 (init_wait_for_inferior): Initialize static vars when a new
5844 main.c (gdbinit): Add new hook for .gdbinit file name, let
5845 it be overridden by config files as GDBINIT_FILENAME.
5846 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
5847 Both of these are used for VxWorks gdb.
5849 mcheck.c: rename include file "gmalloc.c" to avoid problems
5850 with system include file "malloc.c".
5852 param-no-tm.h: New include file, same as param.h but does not
5853 include the default "tm.h" file. This is used in files where
5854 the target is known, e.g. remote-eb.c or sparc-xdep.c.
5856 param.h: Now just a shell that includes tm.h and param-no-tm.h.
5858 remote-vx.c: New file, VxWorks remote debugging support. Uses
5859 RPC routines that are shared with the target system, in directory
5862 remote.c: Vectorize remote interface.
5864 source.c: Globalize source_path, and make an alias "l" for "list"
5865 since we now have the "load" command.
5867 sparc-xdep.c: Use new param-no-tm.h.
5869 symmisc.c (free_named_symtab): Add new function from Wind River.
5870 However, ifdef it out for now while we think about what it should
5873 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
5875 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
5876 non-Unix-children handle this with their own code in the target
5879 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
5880 source and target lists. Add vx-share to default list of include
5881 directories. Add new files to src and target lists: mem-break,
5882 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
5883 ${srcdir} versions of munch and createtags are used.
5885 * valops.c (find_function_addr): Split out of call_function.
5886 (call_function_by_hand): Rename call_function; this function
5887 calls functions in the target by laboriously patching the target
5888 word-by-word with the right stack, args, regs, etc.
5891 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
5893 Handle AMD 29000 a bit better.
5895 * remote-eb.c (readchar): Mask received char log to make it readable.
5896 (remote_start): Pass arguments down to executing program.
5897 Make startaddr unsigned.
5898 infrun.c (start_inferior): Accept args, pass them to
5900 infcmd.c (run_command): Pass args down to start_inferior.
5902 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
5903 the target object file format.
5904 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
5906 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
5907 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
5909 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
5911 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
5912 * TODO: We did a few things, we have more to do though.
5914 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
5915 * inflow.c (inferior_died): Clear deferred stores.
5917 * Debug problems with dummy frames and calls to the inferior.
5918 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
5919 * sparc-tdep.c (do_restore_insn): Simplify.
5920 (sparc_frame_find_saved_regs): Simplify and fix what we find.
5921 (sparc_push_dummy_frame): Simplify and fix what we push.
5922 (sparc_pop_frame): Slightly more hair here, deciding whether
5923 we are restoring a saved PC or returning to a return address in %i7.
5924 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
5926 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
5927 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
5928 * obstack.h (chunkfun): ditto.
5929 * defs.h (xmalloc, xrealloc): ditto
5931 * utils.c (quit): Grab the terminal from the child if necessary.
5933 * inflow.c (term_status_command): Rename to term_info, change
5936 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
5937 (is_delayed_branch): Speed up.
5938 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
5939 Still missing some float ops, and needs testing.
5941 * Support for input and output radixes other than base 10
5942 * defs.h (input_radix, output_radix): Declare.
5943 * expread.y (yyparse, parse_number): Handle changes of input
5944 radix, and ambiguous names-or-numbers in radixes >10.
5945 * printcmd.c (print_scalar_formatted): Print formatted hex
5946 numbers in varying column widths.
5947 * valprint.c (val_print): Use output_format to print scalar ints.
5948 (set_input_radix, set_output_radix, set_radix): Create.
5949 (set_output_radix): Set output_format from output_radix.
5950 (_initialize_valprint): add `set radix' but leave the others off.
5952 * main.c (execute_command): Let stupid questions be turned off.
5953 (_initialize_main): Handle "set stupidity", etc.
5955 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
5956 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
5958 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
5960 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
5961 bfd stuff is still screwed up, but with some manual work, it
5964 * breakpoint.c (bpstat_do_actions): Start over if a command
5965 proceeds the inferior, since the inferior will have stopped and
5966 will need to have its new stop-actions taken care of.
5968 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
5969 compiler fits, simplify it.
5971 * gdb.texinfo (directory command): Doc new dir command.
5972 source.c (directory_command): "dir" now puts things on the front
5973 of the path, moves dups up front, and handles multiple names
5974 on the command line, inserting each one in order. It also
5975 blows away cached line and full_filename info.
5977 * stack.c (backtrace_command): Skip "more stack frames follow"
5980 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
5981 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
5982 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
5983 The only odd one was Gould NP1, which had defined vprintf to
5986 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
5987 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
5988 variable, inspect_it.
5989 valprint.c (print_string, val_print): Use the global inspect_it
5990 to indicate whether to print in Epoch style or normal style.
5992 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
5994 * printcmd.c (call_command): add an alias for the "print" command
5995 which runs expressions and doesn't print the result if void.
5996 (print_command_1): implement it.
5998 * command.c: Remove #if 0'd code. Initialize all the fields
5999 in add_cmd (). Rename do_nothing_command to
6000 not_just_help_class_command, and make it externally visible.
6001 command.h: add user_commands to struct.
6002 * main.c (define_command): Don't overload c->function with a char
6003 string as well as a function pointer.
6005 * eval.c (evaluate_subexp): Reinstall tiemann changes to
6006 calling convention of value_struct_elt () that got dropped in
6009 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
6010 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
6012 * tm-sparc.h (POP_FRAME): replace some constants with defines.
6014 * sparc-xdep.c (store_inferior_registers): defer stores to regs
6015 until a good time (e.g. when we are about to run the child),
6016 saving ptrace calls.
6017 * infrun.c (proceed): handle DO_DEFERRED_STORES.
6018 * tm-sparc.h: define DO_DEFERRED_STORES.
6020 * sparc-xdep.c (store_inferior_registers): when storing float
6021 registers, don't store stack regs too. When storing the SP,
6022 however, DO store the stack regs too. This fixes a bug in which
6023 the dummy frame is not recognized when a call_function finishes,
6024 because its frame pointer (in the stack regs) was never
6026 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
6027 even though we don't know how to read them from an inferior.
6028 valops.c (call_function): Comment about storing SP.
6030 * infrun.c (save_inferior_status): Save away the original bpstat
6031 chain so it can be restored later. Install the copied version for
6032 use by whoever saved the status. It will be blow away by
6033 restore_inferior_status, and the original chain restored. This is
6034 important for people who have pointers into the original.
6036 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
6037 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
6038 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
6041 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
6043 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
6044 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
6045 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
6047 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
6049 * Merge Mike Tiemann's multiple inheritance changes from Sun.
6050 Store the baseclasses in a type struct starting from array element
6051 0 rather than from the unusual array element 1.
6053 dbxread.c: the above.
6054 (virtual_context): Add
6055 Read new debug information about which virtual function table
6056 a virtual function is from, and store it in fn_field.fcontext.
6058 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
6059 TYPE_FN_FIELD_STATIC_P.
6061 symtab.c: the above.
6062 valops.c: the above. Handle pointer casts of object *'s.
6063 (search_struct_method): Add.
6064 (value_struct_elt): First arg is now a pointer to a value, and is
6067 valprint.c: the above.
6068 values.c (value_virtual_fn_field): Add type arg. Handle
6069 offsetting to the proper object when calling virtual fns.
6071 (baseclass_addr): Add valuep arg.
6073 * README: Document the current state of BFD config (missing).
6074 * TODO, ChangeLog, Makefile.dist: Roll version.
6075 * WHATS.NEW: Add summary of changes since 3.5.
6077 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
6079 * dbxread.c (read_struct_type): Clear bit vectors whenever
6081 symtab.c (B_CLRALL): define.
6083 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
6084 using == rather than =. Huh... This fixes the dreaded problem
6085 wherein builtin_type_int becomes TYPE_CODE_FLT.
6087 * core.c (info_files): Show the inferior pid.
6089 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
6090 already knows how to look in the source directory.
6092 * Remove psymtab hair from many places. Remove duplicated code
6093 for searching symbol tables. Hide psymtabs from most places.
6094 Make it fast to get from a psymtab to its symtab.
6096 blockframe.c (blockvector_for_pc): Remove psymtab hair.
6097 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
6098 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
6099 dbxread.c: export psymtab_to_symtab, make it work if called N times.
6100 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
6101 new symtab completely. New psymtabs get symtab pointer
6102 initialized to zero. Remove MI warning printf.
6103 symtab.h: Comments. Add psymtab to symtab pointer.
6104 (PSYMTAB_TO_SYMTAB): New macro.
6105 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
6106 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
6108 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
6110 (print_frame_info): Avoid special-casing symbols that have not yet
6113 * source.c (open_source_file): Quick path if we have already
6114 located the source file by its full name.
6116 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
6117 find_pc_psymtab. When a name is found in the misc function
6118 vector, search the symbol table for its mangled name, not the
6119 name that the user typed.
6121 * bfd.h: Fix missing comment terminators, make #endifs match.
6123 * valarith.c (value_less): Handle unsigned int comparisons.
6124 Add FIXME about pointer compares, which assume host and target
6125 pointers are the same.
6127 * command.c (do_nothing_command): lint
6128 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
6129 fix comments on debug symbol format for visibility. Actually set
6130 visibility of symbols.
6131 main.c (echo_command): lint; use <readline/history.h>.
6132 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
6133 obstack.h (_obstack_blank): Rearrange pointer math to avoid
6134 pointing past end of allocated memory; saber complains.
6135 obstack.h: Declare the external functions that we use.
6136 valarith.h: use <string.h>
6137 solib.c (solib_add): lint.
6139 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
6141 * main.c (initialize_main): Default info_verbose to off, now that
6142 symbol reading is fast.
6143 (quit_command): Avoid clobbering exec_bfd while quitting.
6145 * Initial BFD (binary file diddling library) merger:
6146 coffread.c: Change AOUTHDR to struct exe_hdr.
6148 core.c: initialize initialized data at compile time.
6149 (core_file_command): Move from coredep.c, convert to bfd.
6150 (xfer_core_file): Convert to bfd.
6151 exec.c (exec_file_command): use bfd routines.
6153 mips-tdep.c: Remove exec_file_command and friends.
6156 * coredep.c: (fetch_core_registers) Convert core_file_command to
6157 fetch_core_registers.
6158 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
6160 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
6161 (my_bfd_read): More bogosity, which I don't think we call.
6162 (program_name): Remove this atrocity asap!
6164 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
6167 values.c: allocate_repeat_value was not clearing the
6168 optimized_out field.
6169 (value_static_field): minor stylistic fix (wrong macro was used).
6170 valops.c (value_struct_elt_for_address): didn't work for C++
6173 * signame.c (_initialize_signame): Initialize signal names once.
6175 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
6176 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
6177 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
6179 * remote-eb.c: Support user-settable baud rates on the serial port.
6181 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
6183 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
6185 * tconfig/sun3os4: Remove warning about native assembler,
6186 since it also occurs in the xconfig file.
6188 * findvar.c (registers): Allocate some slop after `registers'
6189 to prevent stray accesses from trashing the next variable.
6191 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
6192 on the sun-3, by changing the #ifdef from `sun3' (which is not
6193 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
6194 vars, which happened to follow `registers' in the executable.
6196 * readline/history.c (history_search): Heed gcc-2's advice
6197 and parenthesize && inside ||).
6199 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
6200 tm-29k.c: Insert FSF copyright headers.
6202 * remote-eb.c: Better comments.
6204 * Makefile.dist: Update to 3.91.6.
6205 * TODO: note PREPARE_TO_STORE problem.
6207 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
6209 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
6211 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
6213 * infrun.c (wait_for_inferior, at end): Don't set up
6214 prev_* if the inferior no longer exists.
6216 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
6217 CANNOT_EXECUTE_STACK.
6218 valops.c (call_function): Use it.
6220 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
6222 * inferior.h (PC_IN_CALL_DUMMY): New macro.
6223 infrun.c (wait_for_inferior, 2 places): Use it.
6225 * values.c (value_being_returned): Only use
6226 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
6228 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
6229 right thing for remote-eb.c.
6231 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
6232 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
6234 * blockframe.c: Put get_frame_saved_regs inside #if !defined
6235 (FRAME_FIND_SAVED_REGS).
6237 * findvar.c ({fetch,store}_registers): Check for
6238 REMOTE_{FETCH_STORE}_REGISTER macro.
6240 * findvar.c (get_saved_register): Add argument lval and
6241 change meaning of argument addr.
6242 findvar.c: Change calls to get_saved_register to reflect
6243 new calling convention.
6244 valops.c (value_assign): Use get_saved_register instead of
6245 find_saved_register.
6247 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
6249 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
6250 an (uninitialized) pointer to one. Use "&" when passing it
6253 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
6255 * coffread.c (getfilename): Use DGUX x_offset and x_name if
6258 * coffread.c (symbol_file_command): Put semicolon after
6260 Put safe_to_init_tdesc_context in #if defined (TDESC).
6261 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
6262 coffread.c: #include <sys/stat.h>.
6263 (read_coff_symtab): Typo: in_source_files -> in_source_file.
6264 Add missing ')' in check for "lc%" and friends. Remove
6266 Declare read_one_sym() at top of file.
6267 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
6268 MC68WRMAGIC can have the same value without causing a duplicate
6271 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
6273 * Allow a Makefile to be built without building the
6274 tm and xm file links that screw up builds in subdirectories.
6275 This is done with `config.gdb none', then you can do things
6276 like `make gdb.tar.Z'.
6277 * tconfig/none: Config file for no target system
6278 * xconfig/none: Config file for no host system
6279 * config.gdb: If no TM or XM files are called out by the
6280 host or target file, don't make links for them.
6282 * cplus-dem.c: Add documentation.
6284 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
6285 simple error, so the user's gdb doesn't crash due to some object
6286 file problem (e.g. somebody is rebuilding the file out from under
6289 * printcmd.c (print_address_symbolic): demangle the symbol.
6291 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
6292 Motorola copyrights in it. Make "make gdb.tar.Z" work.
6293 (alldeps.mak): sort and uniq all results from this; duplicates
6294 hose gdb.tar.Z link building. Remove RCS files from
6295 tconfig and xconfig. Add config files for sun386. Add
6296 a few odd files to OTHERS and HFILES.
6298 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
6300 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
6301 Roll version number to 3.91.5. Make lint work in bindir.
6303 * README: Document cross-debugging and new file structure.
6305 * blockframe.c: Lint. Include "value.h" to declare read_register.
6306 (find_pc_partial_function): remove duplicate line.
6308 * command.h: Lint. Declare error_no_arg and dont_repeat.
6310 * tm-news.h: Remove inadvertently duplicated stuff.
6312 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
6313 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
6315 * config.gdb: Allow `config.gdb host target' form. Clean
6316 up previous change that printed bogus messages when you just said
6319 * core.c: #include "command.h" for lint.
6322 * main.c: Remove some casts of enums. Lint.
6329 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
6331 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
6332 read it from memory. This will allow us to save ptrace calls
6333 eventually. Changed caller single_step too.
6335 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
6336 that we aren't going to use, saving many ptrace calls, especially
6337 when watchpointing or single stepping. Use some #define's for
6339 (store_inferior_registers): Ditto.
6340 (core_file_command): Use some #define's for constants.
6342 * tm-sparc.h: Add #define's for some register numbers, so we
6343 can eliminate the use of random constants in sparc-xdep.c.
6345 * stack.c (frame_command, print_frame_info, up_command,
6346 down_command) Remove frame_changed, since it
6347 causes a bug and doesn't seem to do anything useful. In some
6348 places it was used as a flag, in others as a stack level (?).
6350 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
6351 default is to use the portable (vprintf) version rather than the
6353 * xm-news.h (MISSING_VPRINTF): Add.
6355 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
6357 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
6359 * Remove stuff that forces -Bstatic linking of gdb, and warnings
6360 about linking debugged programs -Bstatic in the sun?os4 config
6361 files in tconfig and xconfig subdirectories.
6363 * main.c (main): Remove unreached exit(0) now that we exit
6366 * Create TODO file for online bug list. There are too many
6367 "little" bugs to keep track of on paper.
6369 * Change Projects file to refer to bug-gdb@cygnus.com
6370 rather than kingdon@ai.
6372 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
6374 * Makefile.dist (VERSION): 3.91.4 now.
6376 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
6377 (condense_misc_bunches): Add sanity check that misc_count is
6378 the same as the number of symbols in the bunch.
6380 * coffread.c: rename init_misc_bunches. Pass an argument
6381 to condense_misc_bunches (a zero).
6383 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
6384 every time we are called; don't rely on our caller to do it.
6385 (add_file): Remove call to init_misc_bunches.
6387 * mipsread.c: Only warn, don't error, if unknown symbol types.
6388 This keeps an old gdb from falling on its face if it sees newly
6389 extended symbol info. Rename init_misc_bunches.
6391 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
6393 * Merge in changes from Per Bothner for DECstations and other
6394 MIPS stuff. The rest is Bothner speaking:
6396 The next message is a merger of Alessando Forin's mips port with
6397 mine. I've tried to use my good if biased judgment to get
6398 the best of both. It *does* need testing.
6400 Some of the changes are general, *not* mips-specific.
6403 Didn't believe in little-endian bit order.
6404 There are still inconsistencies about whether flags
6405 like BITS_BIG_ENDIAN are integer (#if ...) or
6406 boolean (#ifdef ...). I tried to paper over them.
6408 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
6409 Moved some misc_function code that was common to
6410 {dbx,coff,mips}read.c to symtab.c.
6411 In the process, I think I cleaned things up a bit.
6412 At the same time, moved obsavestring and obconcat to symtab.c.
6415 Removed obsolete condense_addl_misc_bunches (use
6416 condense_misc_bunches(1) instead).
6419 Needed to include <sys/dir>, at least on DECstations.
6421 valops.c, mips-tdep.c, tm-mips.h:
6422 Added PUSH_ARGUMENTS macro to support funny argument-pushing
6423 conventions (when STACK_ALIGN is insufficient).
6424 Needed on mips, where doubles need 8-byte alignment,
6425 but ints only need 4.
6428 Removed cruft that was not being used.
6429 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
6432 Print $ before register-names (I think that makes things a little
6434 Never print two instructions, even if one delays.
6435 Removed hex-disassemble set_cmd. (This is not mips-specific,
6436 so I think the argument is whether it is generally worthwhile or not.
6437 I'm inclined to think not, given how easy it is to
6438 convert between radixes in gdb.)
6441 This is basically Alessando's code.
6442 It doesn't use obstacks; I changed it to use obstacks
6443 in a few minor places where using malloc causes a
6444 memory leak. (Probably, more places could/should be changed.)
6445 I added record_misc_function where it was missing.
6446 In symbol_file_command and add_file_command, I tried
6447 to make the code consistent with more recent versions.
6448 Minor sylistic changes in parse_procedure.
6449 Make a .gdbinfo. psuedo-symbol point back to the real
6450 procedure symbol (using the isym field).
6453 This is basically from my port, but with a lot of details
6454 and a number of routines merged in from Alessando's version.
6455 I basically used my code "raw" backtrace (use heuristics
6456 from the actual code, rather than symbol table info) - though
6457 the idea is Alessandro's. I feel my code is a little cleaner
6458 here, particularly in being a little more flexible, such as being
6459 able to handle gcc-produced code (which it now can).
6460 It also doesn't do frame caching (which is not useful
6461 more recent gdb versions).
6462 I also used my code for push_/pop_dummy, more or less.
6463 I tried to incorporate AF's code for testing sigtramp
6464 while backtracing; I probably got it wrong.
6465 Added mips_print_register, which tries to scrunch as much
6466 information as possible on a screen...
6467 Removed the skip-prologue set_cmd. As with hex-disassemble (see
6468 under mips-pinsn.c), I don't see anything mips-specific here,
6469 and I don't see it being all that useful anyway.
6472 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
6473 Use more register names (rather than hard-cases numbers).
6475 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
6477 * Hack up 3.90.11 changes:
6479 * Makefile.dist (depend): parameterize $(GCC).
6480 Add solib.c and solib.o.
6481 (readline): Fix vpath for both absolute or relative SRCDIR.
6483 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
6484 Also, let the part I didn't understand at least compile so
6485 I can test the rest. FIXME.
6487 * dbxread.c: Fix thinko using strcmp.
6488 (init_psymbol_list): declare static.
6489 (partial_symbol_file_open): Comment cleanups better, avoid
6490 cleaning up the string table since the caller will do that.
6491 Move the stat for mod time into symbol_file_command, temporarily.
6492 (There should be a mod time for each symbol file, eventually,
6493 to control its rereading. FIXME.)
6495 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
6496 SunOS, which gives error for shared libs otherwise. (From
6497 Schaefer, probably FIXME needs work for portability.)
6499 * solib.c: Move #include "param.h" to work.
6500 Lowercase all the Uppercase Letters In the Messages.
6501 (find_solib): Clean up inferior_so_name for debug printouts.
6502 Allow no argument, to mean all shared libraries.
6504 * symmisc.c: include param.h to get CLEAR_SOLIB.
6506 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
6508 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
6509 to 3.90.11. ChangeLog entries below are from this.
6511 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
6515 * Makefile.dist (HFILES): Add tm-sunos.h.
6517 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6521 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
6523 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
6525 * sparc-opcode.h Added single-operand version of rett.
6527 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6529 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
6530 Put parens around gcc_p in expansion.
6532 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
6534 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
6536 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6538 * Changes for Sun shared libraries:
6539 blockframe.c (find_pc_partial_function): If a non-text symbol
6540 is found, set *address = pc - FUNCTION_START_OFFSET.
6541 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
6542 Disable breakpoints instead of giving an error.
6543 source.c (select_source_symtab): Initialize cs_pst.
6544 symmisc.c: Call CLEAR_SOLIB if defined.
6545 symtab.h: Make text{low,high} CORE_ADDR not int.
6546 (psymtab): New field addr.
6548 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
6549 (record_misc_function): Give correct type for N_DATA symbols.
6550 (condense_misc_bunches): do "misc_function_count = j" regardless
6552 Take code which is shared between symbol_file_command and
6553 add_file_command and put it into partial_symbol_file_{open,read}.
6554 Split add_file_command into add_file_command and add_file.
6555 Make psymtab_to_symtab read in the string table if the file
6557 Two new parameters to read_dbx_symtab and start_psymtab.
6558 tm-sunos.h: New file.
6560 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6562 * infcmd.c: Change cont_command to continue_command and "cont"
6565 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6567 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
6569 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
6571 * values.c (USE_STRUCT_CONVENTION): Check for structures of
6572 size 1,2,4,8 rather than size < 8.
6574 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
6575 as necessary, not just once.
6577 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
6579 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6581 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
6583 * tm-news.h: Add CALL_DUMMY_*.
6585 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
6587 * config.gdb: In list_host, list_target, use ${i}, not $i.
6589 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6591 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
6593 * sparc-opcode.h: Change all store floating-point state register
6594 instructions to have the right match & lose fields.
6596 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6598 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
6600 config.gdb: If srcdir != ., create readline directory and
6601 copy a makefile into it.
6603 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
6604 consistency with POSIX.
6606 * breakpoint.c (bpstat_stop_status): Disable watchpoint
6607 when we exit its exp_valid_block.
6609 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
6611 * Makefile.dist: Bump version to 3.91.3.
6613 * Clean up handling of breakpoint commands (somewhat).
6614 Prompted by Tiemann bug report "cont 10" doesn't work any more.
6616 inferior.h: Add breakpoint_proceeded to inferior status struct
6617 and globals; save it and restore it.
6618 (clear_breakpoint_commands): Cleanup, remove old #define.
6620 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
6621 (save_inferior_status, restore_inferior_status): handle it also.
6622 (proceed): Remove earlier code that set breakpoint_proceeded.
6623 It is now set only in clear_proceed_status.
6624 (clear_proceed_status): Cleanup, use bpstat_clear rather
6625 than clear_breakpoint_commands. No callers need the stop_bpstat
6626 between clear_proceed_status and proceed.
6628 infcmd.c: Add breakpoint_proceeded definition and comment.
6629 (cont_command, jump_command, signal_command): Move call to
6630 clear_proceed_status right next to call to proceed.
6632 breakpoint.c (bpstat_do_actions): Avoid clobbering our
6633 caller's argument while running down the chain of breakpoints.
6634 Use new variable "breakpoint_proceeded" to determine when
6635 a command that it executes moves the inferior past the
6637 (bpstat_clear): Handle NULL argument.
6638 (bpstat_clear_actions): Avoid useless call to
6639 breakpoint_auto_delete.
6640 (delete_breakpoint): Clean up bpstat's that are pointing to
6641 the deleted breakpoint from the stop_bpstat chain.
6642 (breakpoint_auto_delete): Simplify.
6644 * Clean up handling of EOF, error on stdin, etc. This was
6645 prompted by a network problem that caused gdb to go into an
6646 infinite loop filling up its malloc'd memory.
6648 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
6649 not clear_breakpoints_commands, which is now gone.
6650 (main): If command_loop returns (e.g. from EOF on stdin), do
6651 a quit_command (looping back to command_loop if quit_command
6652 doesn't really quit).
6653 (command_loop): check result from command_line_input and
6654 exit if it returns NULL, rather than passing the NULL to
6656 (gdb_readline): Free malloc'd result space before returning
6659 * utils.c (query): Handle C-d to mean "yes", just as if the
6660 input was not a terminal. Also avoid infinite loop if EOF
6661 occurs in mid-input-line before newline. This allows
6662 query to be used at EOF on stdin with reasonable results.
6664 * infrun.c (proceed): Set breakpoint_proceeded.
6666 * values.c (value_as_long): Avoid infinite recursion for enums.
6667 (_initialize_values): Fix typo in help msg (kingdon).
6669 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
6670 RL_LIB for linking. This allows -lreadline for linking
6671 and nothing for dependencies, once readline is a real library.
6673 * config.gdb: Jim Kingdon: give useful error message if the
6674 host or target type is not recognized.
6676 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
6677 it just defines it. Dumb, but deal with it.
6679 * Jim Kingdon suggests:
6680 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
6682 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
6684 * Makefile.dist (VERSION): Bump version # to 3.91.2.
6686 * Clean up Bothner's changes.
6688 * blockframe.c (clear_pc_function_cache): New function.
6689 * blockframe.c: remake cache_pc_function_* static.
6690 * dbxread.c (symbol_file_command): remove references to
6691 cache_pc_function_* variables.
6692 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
6693 * printcmd.c: Avoid kludging a global variable (addressprint)
6694 to avoid printing the address of a string twice. Instead,
6695 pass the format letter 's' down low enough that it can be seen
6696 to avoid this problem.
6697 (print_formatted): Pass format arg to value_print.
6698 (restore_addressprint): Remove function.
6699 (do_examine): Avoid hacking addressprint, cleanups and such.
6700 (print_frame_args): Add a comment to a Bothner change.
6701 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
6702 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
6703 to wipe out the values cached in blockframe.c.
6704 * symtab.c (find_method): Add comment saying how big you must
6705 allocate to be "big enough". Per being terse again.
6706 * valprint.c (val_print): Handle format letter "s" to print
6707 strings without addresses. Add comment to vtbl printing code
6708 which casts with wild abandon. Rearrange reference-printing
6710 @0xaddr: value (print w/addressprint)
6711 value (print w/~addressprint)
6712 @0xaddr (parameter lists w/addressprint)
6713 or nothing (parameter lists w/o addressprint)
6715 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
6717 * Merge more changes from Per Bothner:
6719 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
6720 annoying) that I tried to improve it. Here are my suggestions.
6722 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
6725 Do automatic de-reference when taking the address of a reference.
6727 Don't deref_ref when printing parameter lists.
6729 More attempts at treating refernences properly.
6731 In val_print, if deref_ref==0, don't print dangling " = ".
6733 Add COERCE_REF macro, which de-references an REF.
6735 * Merge changes from Per Bothner:
6737 * Fixed (Sony news)-specific configuration problems.
6738 * Fixed other problems with using vanilla pcc and libc (enum problems;
6739 assumption that vsprintf exists).
6740 * Some major speed-ups (finc_pc_partial_function now caches a match;
6741 parsing avoids duplicate symbol_lookup calls).
6742 * Changed handling of baseclasses (no longer use baseclasses field
6743 of struct type, use the first n_baseclasses fields instead).
6744 * Various minor changes/fixes, most C++-related.
6747 Cache the most previous match from find_pc_partial_function.
6748 (Save both low and high ends of matching function's pc range.)
6749 This speeds up the loop of infrun.c:wait_for_inferior quite
6750 a bit, and makes step/next commands much zippier.
6752 Added an enum->int cast (otherwise, some compilers barf).
6754 No longer set baseclass offset to 0, since multiple
6755 inheritance now mostly works.
6756 Added a number of casts, to shut up compiler warnings
6757 (after stabs where made enums, not ints).
6758 When discarding a symbol table (in symbol_file_command),
6759 must clear the cache introduced in blockframe.c.
6760 Don't convert $vtbl_ptr_type to vtbl any more.
6761 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
6762 Mask off sign bit emitted by g++ for virtual table offset.
6763 Set voffset to -1 (not 1) for static member functions.
6765 Changed parsing/lexing of names to avoid doing symbol lookup twice
6766 (once when lexing to determine symbol class, once for real).
6767 Now only call symbol_lookup once. Fields of 'this' win especially big.
6769 Subpress printing addr twice in the case of 'x/s addr'.
6771 lookup_basetype_type is no longer used.
6772 Add find_methods as recursive helper function to decode_line_1.
6773 This allows multiple inheritance to work.
6774 Also, once one or more matches has been found, do not look in
6775 base-classes. (Baseclass methods would be overridden, anyway.)
6777 Removed baseclasses array in struct type.
6778 Instead of using baseclasses[i], use fields[i-1].
6779 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
6780 Changed sign convention of voffset (previous was inconsistent).
6782 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
6784 Used to assume existence of vsprintf. Re-written to not need it
6785 if HAVE_VPRINTF is undefined.
6787 typecmp was too pessimistic. Made it less so.
6789 Don't print space after address.
6790 If vtable points to a misc symbol (with 0 offset), print it,
6791 since that indicates the actual class of the object.
6792 Changed ype_print_derivation_info to use new inheritance
6793 scheme (without baseclasses vector).
6795 In value_primitive_field, fixed some bugs left over from previous set of fixes.
6796 Also, changes needed because TYPE_BASECLASSES were removed.
6798 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
6800 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
6803 If there is no path set, and the symbols don't indicate what directory
6804 a file was compiled in, look in the current directory. But either
6805 a path or a known compilation directory will prevent this.
6808 Three independent bug fixes:
6809 * Remove the #if 0 block that breaks some stuff.
6810 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
6811 adapt gdb to either SunOS 4.0.* or 4.1.
6812 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
6815 Instantiate the class T when looking for methods in it. (Tiemann@sun)
6818 (type_print) Demangle the name being printed.
6819 (type_print_base) Handle botched demangling without coredump (tiemann).
6822 (check_stub_method): Document routine.
6823 (tiemann) fix bug for no-arg functions
6824 Avoid clobbering beyond end of malloc'd storage.
6825 Terminate the argument list properly.
6827 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
6829 * Changes merged by John Gilmore:
6832 In breakpoint_1, use new print_address_symbolic instead
6833 of find_pc_partial_function. (This forces use of assembler-level
6834 addresses, and avoids misleading non-mangled source-level names.)
6836 Generalize ansi argument such that -1 means skip arglist totally.
6837 Removed global variable print_ansi_qualifiers (which made
6838 code non-reentrant), in favor of extra explicit arguments
6839 to internal routines.
6841 Add new helper function print_address_symbolic.
6842 Use find_pc_misc_function instead of find_pc_partial_function
6843 (since we want assembler-level symbols here).
6845 Print unknown function as just "f (...)", not "f (...) (...)".
6846 Use new fputs_demangled explicitly.
6848 Fixed a typing violation (problem: value.h cannot be imported
6849 without renaming many variable in this file).
6850 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
6851 decode_line_1: Moved forward some never-reached code.
6852 Made decode_line_2 skip function prologues correctly.
6854 fputs_filtered should not demangle by default.
6855 Add new fputs_demangled to demangle on demand..
6857 Change value_struct_elt to use value_primitive_field (using recursive
6858 utility function search_struct_field). This allows foo.bar to work
6859 for multiple inheritance (so far only for data fields).
6860 Change check_field in the same way (recursive helper function
6861 to support multiple inheritance).
6862 (Note: there are more of these problems that I haven't fixed.
6863 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
6864 value_of_this: 'this' symbol name is now just "this", note "$this".
6866 Don't print static members.
6867 Avoid printing "members of <type>" if there are none.

6879 * infcmd.c -- insert else to avoid 'delete env' coredump when you
6880 delete the whole environment. Karl Berry reported the bug.

6882 trigger an Emacs bug causing it to not be able to find files
6883 when running gdb in a window.
