1 Thu Nov 14 19:27:30 1991 Fred Fish (fnf at cygnus.com)
3 * symfile.c: Add function compact_misc_function_vector() to
4 remove duplicate misc function vector entries. See comments
5 in source for why this is necessary/desirable.
7 * dwarfread.c: Add misc function type parameter to internal
8 record_misc_function(). Remove calls to init_misc_bunches()
9 and condense_misc_bunches(), these are now done in elfread.c.
11 * elfread.c: Add support for reading bfd canonical symbol tables
12 and generating misc function vector entries for global and
13 absolute symbols. Do calls to init_misc_bunches() and
14 condense_misc_bunches() where they will enclose all calls to
15 record_misc_function(), including those in dwarfread.c.
17 Thu Nov 14 17:02:11 1991 Roland H. Pesch (pesch at cygnus.com)
19 * doc/Makefile.in: new targets gdb.me, gdb.ms, gdb.mm

27 that shuffle parameters into other regs.
28 * symtab.c (decode_line_1): Fix bug introduced in Per's change
31 Wed Nov 13 19:51:11 1991 Steve Chamberlain (sac at cygnus.com)
33 * Makefile.in, xconfig/delta88 made it install a sysV manual page;
34 gdb.z into the right place.
36 Wed Nov 13 16:45:13 1991 John Gilmore (gnu at cygnus.com)
38 Motorola 88000 port without tears, I mean without tdescs.
40 * m88k-tdep.c: Blow away all tdesc stuff.
41 Provide functions for all the frame-related macros in
42 tm-delta88.h. Adopt i960-style EXTRA_FRAME_INFO.
43 (examine_prologue, frame_find_saved_regs, skip_prologue): borrow
44 from i960-tdep.c and adapt to the function prologues on the 88k.
45 (read_next_frame_reg): Borrow from mips-tdep.c.
46 FIXME: frame_locals_address should go away.
48 * tm-delta88.h: Dump all the tdesc stuff.
49 Macros for all frame-related stuff call fns of same name.
50 Remove duplicated definitions. FP_REGNUM becomes same as
53 * xm-88k.h: Eliminate lots of library dependencies, now handled
54 in libiberty. Eliminate KDB nonsupport.
56 * doc/gdbint.texinfo: Add rudiments on frames. FIXME, add more.
59 * stack.c (frame_info): Mark frameless functions.
60 Print locals address (FIXME, remove if same).
61 * blockframe.c: Comment changes, FIXME after.
62 * coffread.c: Even without TDESC, need to zap "@" symbols.
63 Don't register for wierd format names; change the names in BFD.
65 * alloca.c, language.c, tdesc.c: Lint.
66 * tdesc.c, tdesc-lib: FIXME: remove these.
68 Tue Nov 12 19:30:22 1991 John Gilmore (gnu at cygnus.com)
70 * Makefile.in: Add tdesc library support. Fixups to lint,

77 Allow setting breakpoints on C++ destructors.
78 * valops.c (destructor_name_p): Don't check TYPE_HAS_DESTRUCTOR,
79 since it lies. Rely on callers to catch missing destructors.
80 * symtab.c (decode_line_1): For example (see above), here.
81 * buildsym.c, symtab.h: Remove TYPE_FLAGS_HAS{CON,DE}STRUCTOR
82 flags since they are no longer used.
84 Fixes to support C++ methods with functional parameters.
85 * c-exp.y (func_mod rule): Allow (and ignore) list of parameter
86 types in a function type.
87 * eval.c (parse_and_eval_type), value.h: New function,
88 parse_and_eval_type, is based on old code from check_stub_method.
89 But don't actually evaluate the cast, since that calls
90 value_cast(), whcih may fail. Just extract the type
91 from the parsed expression.
92 * values.c (check_stub_method): While looping through the
93 arguments, adjust depth *after* parameter has been handled.
94 Replace call and setup of parse_and_eval with new function
97 Tue Nov 12 09:40:07 1991 Fred Fish (fnf at cygnus.com)
99 * utils.c, rem-multi.shar: Remove fixed arg count version of

104 m88k-xdep.c, main.c, printcmd.c, pyr-xdep.c, source.c,
105 sun386-xdep.c, symm-xdep.c, umax-xdep.c, values.c, xcoffread.c:
106 Change all instances of use of fixed args concat() to variable
107 args concat() now located in libiberty.
109 Tue Nov 12 07:23:46 1991 John Gilmore (gnu at cygnus.com)
111 * Makefile.in: Add xcoffread.c, xcoffexec.c.
112 * xcoffread.c: New file for handling AIX mangled-coff files.
113 * xconfig/rs6000, tconfig/rs6000: New files.
114 * buildsym.c: Add hooks for xcoffread.c.
115 * rs6000-pinsn.c, rs6000-tdep.c, rs6000-xdep.c, tm-rs6000.h,
116 xm-rs6000.h, rs6k-opcode.def, rs6k-opcode.h: New files.
117 * xcoffexec.c: New file for handling AIX shared libraries.
119 Mon Nov 11 19:14:31 1991 Fred Fish (fnf at cygnus.com)
121 * core.c: Minor rewording of message to user containing name of
122 (and possibly arguments to) the program that generated a core
125 * elfread.c: Remove the register_addr() stub now that it is no
128 * procfs.c: Move misplaced #endif for ATTACH_DETACH. Add new
129 fetch_core_registers() function for core file support.
131 Sat Nov 9 13:37:57 1991 Fred Fish (fnf at cygnus.com)
133 * dwarfread.c (dwarf_psymtab_to_symtab): Remove leftover call
134 to do_cleanups() which resulted from a previous change.
136 * elfread.c: Re-enable compilation of register_addr() stub
137 whenever it is not supplied by coredep.c
139 Sat Nov 9 00:40:32 1991 John Gilmore (gnu at cygnus.com)
141 Add tracking of object files (that contain symbols) to gdb.
142 This includes a "struct objfile" that owns symtabs and psymtabs
143 that were read in from that binary file.
145 * symfile.h: Add struct objfile. Add pointer to the objfile
146 into the struct sym_fns.
147 Replace global `symfile' and `symfile_mtime' with
148 `symfile_objfile'. Add global object_files chain.
150 * symfile.c: Move param.h above symtab.h.
151 (sort_misc_function_vector): Add.
152 (syms_from_objfile): Was syms_from_bfd.
153 (symfile_open): Now returns objfile.
154 (allocate_objfile): New.
155 (free_objfile): New, replacing free_all_.*symtabs.
156 (symfile_init): Takes objfile arg, puts it in sym_fns result.

158 (allocate_symtab): Takes objfile as new parameter, chains them.
159 Handle INIT_EXTRA_SYMTAB_INFO.

162 * dbxread.c: Make more errors into complaints.
163 (push_subfile, pop_subfile): Move to buildsym.c.
164 (dbx_symfile_read, dbx_symfile_init, fill_symbuf, read_dbx_symtab,
165 start_psymtab, psymtab_to_symtab_1, read_ofile_symtab,
166 dbx_psymtab_to_symtab, ): Use bfd ops, don't use file descriptor.
167 Pass objfile. Change callers.
168 (fill_symbuf, SWAP_SYMBOL): Take bfd as arg.
169 (read_dbx_symtab): Just wipe out new symbols, not all, on error.
170 (end_psymtab): Blow away psymtab if empty.

175 * buildsym.c (end_symtab): Pass objfile.
176 (dbx_lookup_type): Handle null typevector.
177 (dbx_alloc_type): Check file number, not sym number, for -1.
178 (find_symbol_in_list): Add for xcoffread.
179 (start_symtab): Default typevector is empty. Keep reusing same
181 (end_symtab): Take objfile argument and pass it to
182 allocate_symtab. Don't make a symtab if no blocks or symbols.
183 Handle empty typevector.
184 (push_context): New function for context stack nesting.
185 (read_type): Mark FIXME where we need to reintroduce type smashing.
187 * buildsym.h (pop_context): Macro, paired with push_context.
188 (subfile_stack): Move here from dbxread.c.
190 * coffread.c (end_symtab, read_coff_symtab): Take and use objfile arg.
191 (read_coff_symtab): Cleanup by freeing objfile, not all symtabs.
193 * mipsread.c (read_mips_symtab, parse_partial_symbols, parse_fdr,
194 new_psymtab, new_symtab): Take and use objfile arg.
196 * dwarfread.c (scan_compilation_units, start_psymtab,
197 process_dies, end_symtab, dwarf_build_psymtabs,
198 read_lexical_block_scope, read_func_scope, read_file_scope): Take
199 and use objfile argument.
200 (psymtab_to_symtab_1, read_ofile_symtab): Don't take or use file
201 descriptor. Use BFD internal functions instead.
202 (end_symtab): Call global allocate_symtab.
204 * elfread.c, target.c: Minor changes to accommodate objfiles.
205 * symtab.h: partial_symbol_table has no symfile_name member now.
206 (fn_fieldlists voffset): avoid non-int bitfield.
207 (struct symtab): Add objfile * and objfile_chain * of symtabs.
208 (struct partial_symtab): Add objfile * and objfile_chain * of
209 psymtabs. Remove symfile_name.

212 (printsyms_command): Rename from print_symtabs. Add selective
213 listing if 2nd argument given. Print objfile info.
214 (printpsyms_command): Rename from print_partial_symtabs. Ditto all.
215 (printobjfiles_command): New; prints objfiles lists, and checks
216 for consistency of symtab, psymtab, and objfile lists.

223 * defs.h (warning_setup, warning): Declare.
224 * expprint.c (print_subexp, UNOP_MEMVAL case): Lint.
225 * inflow.c (new_tty): Use USE_O_NOCTTY #define.
226 * language.c, printcmd.c (print_scalar_formatted), signame.c,
229 Thu Nov 7 18:26:15 1991 Steve Chamberlain (sac at rtl.cygnus.com)
231 * Makefile.in: link with libiberty after libreadline, since
232 readline might want something in libiberty.
233 * m88k-xdep.c: Fixed the register offsets in the ptrace_user
234 struct for BCS 88k machines.
235 * xm-m88k.h: don't define USIZE if already defined.
236 * configure.in: Added delta88 target.
238 Thu Nov 7 04:51:19 1991 John Gilmore (gnu at cygnus.com)
240 * am29k-pinsn.c, am29k-opcode.h: Fix decoding of mtacc, dmac, fmac.
242 * tm-*.h: Remove READ_DBX_FORMAT, COFF_FORMAT, and
243 READ_MIPS_FORMAT, which have been unused since BFD. Still
244 remaining is COFF_NO_LONG_FILE_NAMES.
245 * tm-sun3.h, tm-altos.h: Remove detritus accidentally left from
246 function calling code moved to m68k-tdep.c.
248 Wed Nov 6 17:21:59 1991 John Gilmore (gnu at cygnus.com)
250 * coffread.c: Eliminate c_nsyms in favor of c_naux.
251 Complain if no auxents on .bf and .ef FCN symbols, and assume
252 lots of line numbers.
253 (init_linenos, enter_linenos): Use a sentinel at the end of the
254 read-in linenos, to make for a fast, safe loop-end test.
256 Wed Nov 6 02:54:08 1991 Steve Chamberlain (sac at cygnus.com)
258 * coffread.c (read_coff_symtab): coffread used to rely on the
259 x_sym.x_misc.x_lnsz.x_lnno field giving the # of linnos in a
260 function. Two of the formats I'm using (29k and 88k) don't seem to
261 set it. Ths patch to fcn_last_line and (enter_linenos) is an
262 attempt to use the actual size of the linno table in the file to set
263 the number of linenos to process.
265 Tue Nov 5 22:47:46 1991 Steve Chamberlain (sac at cygnus.com)
267 * Makefile.in: put a - infront of the mv y.tab.c c-exp.tab.c and
268 mv y.tab.c m2-exp.tab.c, so that if bison is used, and the files
269 are created in place, so the mv fails, then the make continues.
271 Tue Nov 5 16:47:47 1991 Per Bothner (bothner at cygnus.com)
273 Add C++ as a separate language.
274 * defs.h (enum language): Add language_cplus.
275 * dwarfread.c (end_symtab): Support language_cplus.
276 * c-exp.y: Add new struct language_defn cplus_language_defn.
277 Don't set c to be the default language (see main.c).
278 * c-exp.y (yylex): Only look for field of this if
279 language is C++. (First difference from C!)
280 * language.c: Add case branches for C++ (currently, all
281 the same as C). Also, add c++ to "usage" note for "set lang".
282 * valprint.c (typedef_print). Add case branches for C++.
283 * main.c (main): New way to set initial language: Look at
284 file extension of psymtab containing main(). (Same as we
285 do for symtabs, but avoid loading the symtab yet.)
286 * symtab.c: New routine find_main_psymtab(), used by main()
287 to set initial language.
288 * symfile.c (allocate_symtab): Move code for mapping file
289 extensions-> languages to new deduce_language_from_filename().
291 Fix a C++ problem when looking for methods in super-classes.
292 There was confusion between base and derived types.
293 * valops.c (value_fn_field): Change function interface.
294 * values.c: Use new value_fn_field interface.
296 Mon Nov 4 10:49:33 1991 Per Bothner (bothner at cygnus.com)
298 * infrun.c: Fixed typo in comment.
299 * utils.c: All the v*fprintf emulation is now in libiberty,
300 so we can get rid of some junk.
301 * xm-sun3os4.h, xm-sun4os4.h, xconfig/decstation, xconfig/i386sco,
302 xconfig/sun3os4, xconfig/sun4os4: Don`t need HAVE_STRSTR any more.
303 * m68k-pinsn.c (print_insn_arg): Support BB/BW/BL
304 type operands, as used by branch instructions.
305 * gmalloc.c: Fix prototype of memcpy.
306 * elfread.c: Comment out register_addr, since it conflicts
307 with the one in coredep.c.
308 * buildsym.h: Remove extern declarations of two functions
309 that are really static in buildsym.c.
310 * tm-mips.h: Add symbolic names for more registers.
311 * mips-xdep.c (store_inferior_registers): Use new register names.
312 * xm-mips.h: Simplify REGISTER_U_ADDR, since it is now
313 only used for core files, not ptrace. Therefore,
314 the KERNEL_U_ADDR hack is no longer needed.
315 The mapping to ptrace number is now in in mips-xdep.c.
316 * mips-xdep.c: Define REGISTER_PTRACE_ADDR (using the
317 mapping from the old REGISTER_U_ADDR), and use it
318 in {fetch,store}_inferior_registers.
319 * mipsread.c: Rename #include ecoff.h to new name coff-mips.h.
320 * mips-tdep.c (mips_push_dummy_frame, mips_pop_frame):
321 Save/restore FP regs correctly (?).
322 * dbxread.c: Remove duplicate define_symbol and type_synonym_name
323 (these had been previously moved to buildsym.c).
324 Hence, define_symbol becomes extern instead of static.
325 * buildsym.c (read_struct_type): Comment out bogus handling
326 of C++ operator methods. Minor hacking of reading of class
327 contexts. Make define_symbol non-static, so dbxread.c can call it.
329 Fri Nov 1 11:05:47 1991 John Gilmore (gnu at cygnus.com)
331 * mipsread.c (read_mips_symtab, read_the_mips_symtab): Use real
332 filename with error messages.
333 * stack.c (frame_select_command): Rename to select_frame_command
334 to avoid "fr" and "fra" having nonunique completions.
335 * symfile.c (sort_symtab_syms): Ignore sort of zero symtab *.
336 (symfile_init): Print file format name when unable to handle it.
337 (free_named_symtabs): Use BLOCKVECTOR rather than obsolete BLOCKLIST.
338 * symmisc.c (free_symtab): Only free linetable if nonzero.
339 * symtab.h: Remove obsolete BLOCKLIST macros.
341 Thu Oct 31 18:12:43 1991 Stu Grossman (grossman at cygnus.com)
343 * infrun.c (wait_for_inferior): another stepi/nexti fix. Ensure
344 that stop_step is 1 at bottom of main loop. I don't know why this
345 needs to be done, but it helps me sleep better at night.
347 Sun Oct 27 18:18:39 1991 Stu Grossman (grossman at cygnus.com)
349 * main.c (initialize_history): Read history after reading all
352 Sun Oct 27 14:09:25 1991 John Gilmore (gnu at cygnus.com)
354 * buildsym.c: Break out initial malloc sizes.
355 (record_line): Record directly in a subfile. Alloc on demand.
356 (compare_line_numbers): Add from xcoffread.c.
357 (end_symtab): New params say whether to sort pendings and
358 linetable. Patch block stabs if defined. Shrink linetable before
359 allocating the symtab.
360 * buildsym.h: Delete line_vector* and prev_line_number. Add
361 global_stabs and file_stabs for xcoffread.
362 * dbxread.c (start_subfile): Move to buildsym. Change above calls.
363 * symtab.h: LINETABLE(symtab) can now be null. Zap LINELIST.
364 * symmisc.c, symtab.c: Cope with null LINETABLEs.
366 * blockframe.c: Pass fromleaf to INIT_EXTRA_FRAME_INFO.
367 * tm-29k.h, tm-88k.h, tm-i960.h, tm-irix3.h, tm-mips.h, tm-pyr.h,
368 tm-sparc.h: Accept fromleaf parameter.
369 * c-exp.y (yyerror): Pass error message if given.
370 * configure.in: Add rs6000 host and target.
371 * inflow.c (new_tty): O_NOCTTY kludge for RS/6000.
372 * symfile.h (entry_point): Add.
374 Sat Oct 26 00:16:32 1991 John Gilmore (gnu at cygus.com)
376 * buildsym.c: New file. Breaks out symbol-table-building routines
377 from dbxread.c, so they can be shared with xcoffread.c.
378 * buildsym.h: New file. Declarations for buildsym.c users.
379 * dbxread.c: Remove large chunks into buildsym.c.
380 * Makefile.in: Add buildsym.c and buildsym.h.
382 * symfile.c (syms_from_bfd): New routine.
383 (add_symbol_file): Call it to do the real work.
384 (syms_from_bfd): Initialize entry_point before calling symfile_init.
385 * symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
386 Avoid declaring or setting entry_point (symfile.h & symfile.c cope).
388 Fri Oct 25 10:58:16 1991 Mark Eichin (eichin at cygnus.com)
390 * cplus-dem.c (cplus-demangle): added support for templates, static
391 data, and the new (correct) mangling for destructors.
393 * dwarfread.c: (dwarfwarn): created a varargs version of
394 dwarfwarn, for non __STDC__ compilers.
396 * c-exp.y: (yylex): added match for "template" token.
397 (typebase): added TEMPLATE name '<' type '>' clause, for explicit
398 specification of template types.
400 * symtab.c: (lookup_template_type): new function for finding
401 templates in symbol table.
402 (type_name_no_tag): changed to explicitly check for s/u/e at the
403 beginning of the symbol - if it is a template, none of these will
404 be there (but the name will still contain spaces.)
406 Fri Oct 25 18:59:32 1991 Per Bothner (bothner at cygnus.com)
408 Various fixes to improve g++ debugging.
409 * symtab.h: Add is_const and is_volatile flags for each method.
410 These are bit fields - take their space from voffset,
411 which shrinks to 30 bits. Since voffset is now a bitfield,
412 make it unsigned for portability. This changes its interpretation
413 slightly: Static methods now have voffset 1 instead of -1,
414 and virtual offsets start at 2, not 1.
415 * symtab.c: Renamed gdb_mangle_typename to gdb_mangle_name,
416 since it now returns an entire magled method name, not just
417 the type part. This avoids some duplication.
418 It also allows us to correctly mangle const and volatile
419 methods (using the new is_const and is_volatile bit fields
421 * valprint.c (type_print_base), values.c (check_stub_method):
422 Simplify by using new gdb_mangle_name.
423 * values.c (value_headof): Fix to correctly handle single
424 inheritance (actually two fixes, either of which suffices).
425 * dbxread.c (read_struct_type): Handle const and volatile
427 * dbxread.c (read_struct_type): Yet one more place where
428 we must handle '\\' continuations.
429 * valprint.c (vtbl_ptr_name): Add final '\0'.
431 Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com)
433 * tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of
434 short return values for sparc and 68k. Patch from Paul Eggert.
436 * coffread.c, coredep.c, i386-xdep.c: install patches for
437 SysV/386 3.2 from Mauro DePalma.
439 Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
441 * core.c (core_file_info), exec.c (exec_file_info): Print file
442 type. Use printf_filtered.
444 * valops.c (value_fetch_lazy): Avoid 0-length fetches.
446 Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
448 * dwarfread.c: Add casts to remove compiler warnings.
450 * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
451 tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
452 tm-sun3.h: Remove locally duplicated code for calling functions
453 in the inferior. The only differences were in the specific trap
454 vectors used and whether or not an fpu was present. These are
455 now handled by appropriate definitions of BPT_VECTOR and
456 HAVE_68881 respectively. Other minor obvious cleanups.
458 * valops.c: Correct a minor misspelling.
460 * utils.c: Remove local BSD/USG hacks that are now in libiberty.
462 * dwarfread.c: Remove prototype for dwarfwarn. Does not work
465 Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
467 * stack.c (frame_command): Always print. Use new
468 frame_select_command to select a frame without printing.
470 * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
472 Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
474 * dwarfread.c: New file for DWARF debugging format support.
476 * elfread.c: New file for ELF object file format support.
478 * procfs.c: New file for SVR4 /proc (process file system) support.
480 * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
483 * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
485 * xm-m68k.h: New file for host machines with m68k cpu.
487 * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
488 Add elfread.o and dwarfread.o to OBS.
490 * symfile.h: Add "elf" to list of supported formats in comment.
492 * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
493 types to gdb, builtin_type_long_double, builtin_type_complex, and
494 builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
495 TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
496 TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
497 TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
498 types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
500 * infrun.c: When using SVR4 /proc interface instead of ptrace(),
501 call proc_set_exec_trap() to setup child to stop at first instruction.
503 * inftarg.c: When using SVR4 /proc interface, call proc_wait()
506 * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
507 supply_fpregset(), and fill_fpregset(), which are machine
508 dependent support routines for SVR4 /proc interface.
510 * utils.c: Add warning_setup() and warning(). Warning() behaves
511 the same as error() except that it returns normally rather than
512 jumping back to command level. Modules that don't want to call
513 warning() for some reason, but want to produce their own warnings,
514 can call warning_setup() to ensure compatibility with the way
515 warning() and error() deal with the terminal.
517 * symtab.c: Make internal errors produce more useful messages.
519 * tm-68k.h: Move code that is duplicated in almost every single
520 m68k based machine's configuration files to this common file.
521 Duplications in the configuration files still need to be removed
524 * infrun.c (child_create_inferior): System V versions must call
525 setpgrp() with no arguments, to comply with prototyping typically
528 * munch: Add support for SVR4 style nm output.
530 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
531 file specific fields from the partial symbol table structure and
532 replace them with a pointer to private data for each different
533 flavor of object file reader to initialize appropriately.
535 Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
537 * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
540 * mipsread.c (fixup_undef_type): New function. If a struct /
541 union / enum is defined in a header file but nowhere else used,
542 (by typedefing, pointer referencing or declaration) the mipsread code
543 builds the complete tree for the structure but leaves its code as
544 TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
545 Guess its type based on the details of the members.
547 Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
549 * infrun.c (wait_for_inferior): Check return value from
552 Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
554 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
555 by my last edit to this routine.
557 Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
559 * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
560 FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
561 the values before putting them into the dummy code. (From Peter
564 Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
566 * configure.in: added ebmon target.
568 Wed Oct 16 22:49:58 1991 John Gilmore (gnu at cygnus.com)
572 * Makefile.in: Roll VERSION to 4.2.
573 * README, TODO, WHATS.NEW: Update.
575 * core.c (core_open): Improve error message for bad file.
576 Pass .reg virtual memory address to fetch_core_registers to help
577 it find the registers in the core-file header.
578 * coredep.c (fetch_core_registers): Take new argument, use it,
579 and pass it to register_addr to locate the block of registers.
580 * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
582 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
583 Sequent N_FN_SEQ like everybody else's N_FN.
585 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
586 * tm-i386v.h: #endif guck.
587 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
588 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
589 * xconfig/tahoe: Add REGEX, which seems to be missing.
591 * coredep.c: Add <sys/types.h> for SCOnix.
592 * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file.
593 * printcmd.c (print_formatted): Flush output before disassembly.
595 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
597 * doc/refcard.tex (sec "Working Files"): consistent metavars and
598 other improvements, due to comments by François Pinard
599 (pinard@iro.umontreal.ca)
601 * doc/gdb.texinfo (appendix "Installing GDB"): changes in
602 configure, and improvenets related to Pinard's refcard comments
604 Tue Oct 15 08:45:12 1991 John Gilmore (gnu at cygnus.com)
606 Changes from Fred Fish:
607 * tm-68k.h (FPI_REGNUM): Add.

621 * i387-tdep.c (double_to_i387): Fix typo for double_to_ieee_extended.
622 * utils.c (_initialize_utils): If !ISATTY, don't paginate.
623 * configure.in, tconfig/decstation, xconfig/decstation: Rename
624 dec3100 to decstation.
626 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)
628 * doc/gdb.texinfo: Catch up to changes recorded here in ChangeLog
629 (nodes Continuing and Stepping; Memory; Targets) clarifications
632 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
634 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move
635 REGISTER_U_ADDR to corresponding xm- file. Sugg. by Peter Schauer.

640 generic routines for calling inferior functions.
642 * blockframe.c (inside_main_scope, inside_entry_scope): New.
644 * copying.awk: Filter formfeeds out of copying & warrantee.

651 core-file reading code.
652 * core.c (get_core_registers): Avoid coredump if no .reg section.
654 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
656 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
657 This avoids coredumps under `set print object on' in value_headof
658 (called erroneously by value_from_vtable_info) for `p &struct'
659 or `p *struct'. From Peter Schauer.
661 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
663 * Makefile.in: Roll version to 4.1.2.
664 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
665 size from BFD (but, FIXME, we don't yet read external nlists's and
666 convert them to internal nlists's before handling them -- we still
667 assume they have the same size and alignment.) Use SET_NAMESTRING
669 * exec.c (exec_file_command): Move dead coff-encapsulation code
671 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.
673 Fri Oct 4 22:30:06 1991 John Gilmore (gnu at cygnus.com)
675 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
676 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
678 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
680 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
681 * mips-xdep.c (store_inferior_registers): Don't try to
682 write the (pseudo) FP.
683 * mipsread.c (parse_partial_symbols): Improved algorithm for
684 setting pst->texthigh.
686 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
688 * doc/Makefile: make TEXINPUTS include . everywhere
690 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
692 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
693 vestiges of typevectors, which were for symsegs and are no longer
694 used. (From a question by Eliot Dresselhaus
695 <dresselh@RFT30.nas.nasa.gov>).
697 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
699 * dbxread.c, coffread.c: static-ize functions that were
700 gratuitiously external. (From Fred Fish.)
702 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
704 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
705 until it is large enough.
707 * dbxread.c (read_type): Handle error case slightly better.
708 Make complaint message not C++-specific.
710 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
712 * infrun.c (wait_for_inferior): Fix step/next so that you only
713 stop at the beginning of a new line. This fixes various problems
714 with for loops, nested if-else's and switch statements.
716 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
718 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
719 between symtabs and psymtabs become ordinary error()s.
721 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
722 properly, making "end pc" correct in shared lib psymtabs.
723 (From Guy Harris <guy@auspex.com>.)
725 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
727 * dbxread.c: Enable, but soften, const_vol_complaint.
728 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
729 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
730 should be file-scope, not global.
731 (read_struct_type): Remove ancient multiple-inheritance warning.
732 (read_range_type): Check base type, complain & patch if undefined.
733 * stack.c (frame_info): Demangle the function name in `info stack'.
736 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
738 * eval.c (evaluate_subexp_for_address): Don't use
739 TYPE_POINTER_TYPE directly (it might be zero if this type has
740 never had a pointer created before); use lookup_pointer_type.
741 * symtab.c (lookup_method_type): Arguments were swapped in all
742 callers, so fix it here. I'm amazed this worked at all!
744 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
746 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
747 "bss" rather than "data" symbols, but which still conflict.
750 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
751 * core.c (core_files_info): Shorten output.
752 * exec.c (exec_files_info): Ditto.
753 (build_section_table): Ignore zero-length sections.
754 * language.c, printcmd.c: Lint.
755 * language.h (get_frame_language): Declare.
756 * saber.suppress: update.

767 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
768 (Reported by Mark Peek <mark@imagen.com>.)
770 * solib.c (solib_map_sections): Relocate all sections, even
771 though only the text section's size is tracked. Mark ld_text
772 for eventual elimination as we generalize to N sections.
774 * infrun.c (wait_for_inferior): Don't check if the PC is in a
775 call_dummy if we were stopped by a random signal that is being
776 passed to the program. This produced wierd results when calling
777 functions in the inferior and signals (e.g. SIGALRM) were in use.
779 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
781 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
782 Bugfix from Paul Eggert <eggert@twinsun.com>.
783 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
784 * valprint.c (print_floating): Print 9 digits for IEEE floats.

798 * language.c (set_language_command): Print useful help message,
799 and restore the language string after giving help.
800 * valprint.c (typedef_print): Print typedef in C or M2.
801 * symtab.c (list_symbols): Use it.
802 * main.c (main): Avoid any output before (gdb) prompt when -q.
803 * language.c (set_language_command): Handle errors by restoring
804 the language string to its current state (fix from A. Beers).
805 * doc/gdbint.texinfo: Roll in information from README. Rearrange
806 "how to install" and "how to print the doc" stuff so it drops
808 * configure.in: Rename rtpc CPU to romp to match config.sub.
809 * README, WHATS.NEW, TODO: Update for gdb-4.1.
811 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
813 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
814 autoloading shared libs, copyright etc on GDB startup, clean up $_
815 and $__ index refs, set/show listsize and related updates to list
816 cmd. New host/target configs.
818 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
820 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
821 from main Makefile.in version definition
822 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
824 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
826 * doc/gdb.texinfo: merge new language-switching and lang-specific
829 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
831 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
832 compilers (which may lack stddef.h).
834 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
836 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
837 N_WARNING are the same except for the N_EXT bit, so just use their
838 values alone, rather than OR-ing them with N_EXT.
840 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
842 * mipsread.c (parse_lines): Deal with negative extended line
845 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
846 global symbol conflicts.
848 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
850 * .gdbinit: Move 'set complaints' to top, so it runs even in
851 case we aren't debugging GDB.
852 * language.c (_initialize_language): Fix type check and range
853 check documentation strings.
854 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
855 language.c can use it. (Though language.c should really not be
856 handling warnings/errors the way it does, FIXME.)
857 * symtab.c (lookup_primitive_type): const lint.
859 Bugfix from Peter Schauer:
860 * source.c (lines_to_list): Make signed, to avoid comparison
861 going unsigned and complaining that -3 is too high for 21 lines.
862 * stack.c (lines_to_list): Ditto.
864 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
866 * Makefile.in (HFILES): Add minimon.h.
867 (VERSION): Roll version number to 4.0.95.
868 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
869 New rules for building distributions. Normal distribution
870 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
871 one level up from here; it calls make-proto-gdb.dir to build a
872 directory `proto-gdb' which is an image of the release. The old
873 `gdb.tar.Z' rule still works too.
874 * config.sub, configure: Roll in latest from ..
876 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
878 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
879 new-target, and new-config chapters; fix minor typos; come closer
880 to usual GNU markup conventions for @file @samp @code @var.
882 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
884 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
885 * mipsread.c (parse_partial_symbols): Enter the name of all

887 symtab is not read in.
888 * mips-tdep.c: Remove some unneeded #includes.
889 * xconfig/dec3100: Add HAVE_STRSTR.
891 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)

1000 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
1002 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
1003 entries are enclosed herein. Not all of these changes
1004 have been merged into the master GDB sources -- check the
1005 ChangeLog above here for the merge log.
1007 Mon Jun 3 17:05:45 EDT 1991
1009 m2-exp.y Created. Tested outside of GDB for a few days. Proper
1010 operators were added, C specific operators and tokens
1011 removed. yylex() revamped to some extent. Still things
1012 missing from the grammar, such as sets.
1013 Tested for two weeks in GDB v3.5.
1015 Tue Jun 11 17:23:48 EDT 1991
1017 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
1018 so they are built-in. Sort of a hack.
1020 Fri Jun 14 12:53:51 EDT 1991
1022 m2-exp.y Added range checking for numeric constants. Any numeric
1023 constant is assumed to be of builtin type INTEGER unless:
1024 (1) it is octal or hexadecimal, in which case it is a
1025 CARDINAL; (2) it is too big to fit into an INTEGER, in
1026 which case it is a CARDINAL.
1027 eval.c Added simple range checking for +, -, and * on integers.
1028 Doesn't work very well for *, since 6 * 1,000,000,000 =
1029 1,705,032,704, which fails the simple test of result >=
1030 first_operand, no matter in what order the operands are.
1032 Tue Jun 18 14:11:30 EDT 1991
1034 Broke the parser into parts, one containing the C grammar and the other
1035 containing code to be shared by all of the grammars.
1037 The following files no longer exist:
1042 The following files were added:
1044 c-exp.y (The C grammar)
1045 m2-exp.y (The Modula-2 grammar)
1046 parser-code.c (Code that is shared by the above grammar)
1050 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
1051 now necessary to use the Bison compiler compiler, since it
1052 will generate function/variable prefixes other than yy.
1054 Tue Jun 18 16:47:49 EDT 1991
1056 symtab.[ch] Added the external variable working_lang, than holds the
1057 value of the current working language.
1058 Added the ennumerated type language_mode, with the values
1059 language_auto and language_manual, the former meaning that
1060 GDB sets working_lang as needed, and the latter meaning
1061 that the value of working_lang is totally under user
1063 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
1064 REAL, BOOLEAN and CHAR. Also added the type codes
1065 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1066 utils.c Added set_language_command and show_language_command to
1067 implement the GDB support commands "set language" and
1069 expression.h A number of identifiers were added to the type exp_opcode
1070 to facilitate Modula-2 builtin functions, integer
1071 division, and array indexing.
1073 Wed Jun 19 13:25:58 EDT 1991
1075 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
1076 if the language specified by working_lang requires the use
1077 of strict typing of expressions. Eventually, even this
1078 will be able to be changed by the user.
1079 Added the macro RANGE_CHECK, which evaluates to non-zero
1080 if the language specified by working_lang requires the
1081 checking of a value against the domain of its type.
1082 Eventually, even this will be able to be changed by the
1084 language.[ch] Predicates involving types (simple_type, ordered_type,
1085 same_type, integral_type, numeric_type, character_type,
1086 boolean_type, float_type) are added. These predicates are
1087 based on the current value of working_lang, and are handy
1090 Wed Jun 19 15:39:34 EDT 1991
1092 eval.c Added the function type_array_rank which computes the rank
1094 valarith.c Added the funtion value_bool, which when given a integer
1095 value.h value (ie. struct value *) as an argument, it returns a
1096 boolean value (ie. struct value *) true if that integer
1097 is non-zero, and a boolean value false otherwise.
1098 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
1099 will print out properly.
1101 Wed Jun 19 16:36:34 EDT 1991
1103 valops.c Added the function value_capitalize, which returns it
1104 value.h argument capitalized if its argument is a lowercase
1105 letter, or the argument unchanged if its argument is not a
1107 valarith.c Added the function range_check_p, which returns non-zero
1108 value.h if its value argument is between the integral bounds upper
1110 Added the function range_check_enum_p, which makes sure
1111 that its value argument is a valid member of the domain of
1113 Added the function range_check_range_p, which makes sure
1114 its value argument lies between the upper and lower bounds
1115 of its type argument, which must be a ranged type.
1116 Added the function check_array_index, which range and type
1117 checks an index of an array.
1118 Added the function value_multi_subscript, which computes
1119 array[idx1,idx2...idxN], given a value array and an array
1120 of values representing indicies.
1121 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
1122 unpack_long to work with TYPE_CODE_BOOL and
1125 Wed Jun 19 18:04:08 EDT 1991
1127 symtab.c Stored pervasive types in a structure and make
1128 lookup_pervasive_type() a lookup function that was based
1129 on working_lang. If lookup_pervasive_type() returned
1130 non-zero, then that value was returned (a fix, since
1131 before it simply wouldn't return the pervasive type.)
1132 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
1133 non-zero if the language specified by working_lang means
1134 "conversion" when it says "cast".
1135 valops.c Added the function value_real_cast(), which performs a
1136 value.h *cast*, not a *conversion*, which is what value_cast()
1137 does when it can. In particular,
1138 value_cast(<float_type>,4) = 4.0, while
1139 value_real_cast(<float_type>,4) = some mess.
1140 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
1141 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
1142 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
1143 and MIN on integral types. *NOTE*: These are currently
1144 hardcoded to work only if there are 8 bits per storage
1146 eval.c Made logical functions call value_bool to return a
1147 properly typed boolean value, based on working_lang.
1149 Thu Jun 20 11:55:27 EDT 1991
1151 valprint.c Types now print out in a Modula-2 fashion. This works for
1152 the cases when the type is printed out step-by-step, that
1153 is, it doesn't work when the name of a structured type
1154 (which includes the keyword "struct", etc.) is simply
1156 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
1157 since type specifications in C and Modula-2 are very
1158 different. The C printing of a type is very recursive,
1159 whereas in Modula-2 it is generally very simple. C has
1160 type prefixes and suffixes, which have no real analogue in
1161 Modula-2. Maybe type_print() should call a language
1162 specific type printer. This is also advantageous if we
1163 compile GDB to exclude some of the languages. We'll just
1164 leave those functions out.
1166 Thu Jun 20 16:57:10 EDT 1991
1168 dbxread.c When reading the complete symbol table in (via
1169 psymtab_to_symtab()), the number and types of function
1170 arguments are added to a function type. define_symbol()
1171 calls add_param_to_type() to accomplish this.
1172 Assumption: when we come across a function definition
1173 (N_FUN symbol with an 'f' or 'F' in the name), its
1174 arguments will appear before another function definition.
1175 When a function is found, a pointer to its type is placed
1176 in the global in_function_type. Changes that
1177 add_param_to_type() makes are to this global.
1178 valprint.c The type of a function now includes (for Modula-2) the
1179 types of its parameters.
1180 eval.c Type checking and a check for the proper number of
1181 arguments is now done for function calls. Not sure of the
1182 impact this has on C++ member function yet.
1184 Thu Jun 20 19:58:48 EDT 1991
1186 valprint.c Rewrote the type printer. Broke it into two language
1187 specific parts, adding the functions type_print_m2() and
1189 An unfortunate consequence is this: if you debugging a C
1190 program in Modula-2 mode (why?), info types does not work
1191 well with regular expressions, since the types are printed
1192 out in Modula-2 terminology, but stored in C terminology.
1193 language.[ch] Added the functions new_type_last(), type_keyword(), and
1194 type_sep() to aid in the printing of typedefs.
1195 symtab.c Made the printing of typedefs as language independent as
1196 possible through calls to new_type_last(), type_keyword(),
1199 Fri Jun 21 11:50:26 EDT 1991
1201 dbxread.c Check all incoming ennumerated types. If it looks like
1202 Modula-2's BOOLEAN type, then change the type_code of the
1203 type to TYPE_CODE_BOOL so we can process it as a boolean
1205 valprint.c Replaced some of the 0x%x with calls to sprintf and
1206 hexformat() in val_print().
1207 language.[ch] Added the function hex_to_string(), which converts its
1208 integral argument to a hexadecimal number (format is
1209 language based) and returns the result as a string.
1211 Mon Jun 24 12:25:07 EDT 1991
1213 valprint.c Some functions call type_print_1() directly, instead of
1214 value.h using type_print(), so they can specify where (column) to
1215 print things. Since type_print() takes care of language
1216 dependence, that needs to be called first. Added a
1217 parameter depth to type_print() (so it is now like
1218 type_print_1). Changed type_print to type_print_at, and
1219 made type_print a macro that passes a depth argument of
1221 symmisc.c Changed all calls to type_print_1 to calls to
1223 Makefile.dist Made it possible to build GDB for a specific set of
1224 depend languages. Do this by passing a definition for the macro
1225 LANGS to make. LANGS should be a string containing a
1226 space-separated list of language names (ie. LANGS="c m2").
1227 The default is to build all languages. Note that grammar
1228 files must follow the naming convention of <lang>-exp.y.
1229 gdb.lang This holds the current value of the LANGS macro. It is
1230 examined every time make is called, and is updated if
1232 eval.c Added #ifdef _LANG_<lang> to these files.
1233 expread.c Still need to add them to dbxread.c and coffread.c.
1241 Mon Jun 24 16:33:11 EDT 1991
1243 language.[ch] Added the functions hexformat_pre() and
1244 hex_to_string_pre(), which take a prefix argument to
1245 include in the format string. Thus, hexformat_pre("08") will
1246 return "0x08x" (if the working language is language_c).
1247 Made hexformat() and hex_to_string() calls to the above
1248 with "" as the prefix argument.
1250 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
1251 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
1252 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
1253 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
1254 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
1255 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
1256 valprint.c, vax-pinsn.c
1258 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
1259 calls to hexformat() and hex_to_string(). Format strings without
1260 the leading "0x" were ignored.
1262 depend Updated to take the above into account.
1265 Tue Jun 25 15:27:18 EDT 1991
1267 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
1268 and type_check_t to keep track of the current state of
1269 range and type checking.
1270 main.c Added the variables range_mode, range_check, type_mode,
1271 and type_check to record the current state of range and
1272 type checking. Added initialization code to main().
1273 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
1274 the above variables.
1277 Tue Jun 25 17:57:08 EDT 1991
1279 dbxread.c process_one_symbol() updates the variable (enum language)
1280 source_lang based on the extension of the filename
1281 contained in the N_SO sybmol that started this symtab.
1282 When end_symtab() is called, the value of source_lang is
1283 put into the language field.
1284 stack.c select_frame() sets working_lang (and possibly type_check
1285 and range_check) to the language field of the symtab
1286 associated with the frame that is selected if working_mode
1287 is language_auto. If working_mode is language_manual, a
1288 warning is printed and working_lang is not set.
1289 language.c Added the function set_type_range(), which sets the value of
1290 type_check and range_check (if their modes call for
1291 automatic setting) based on the current value of
1292 working_lang. A non-zero argument will cause the current
1293 settings to be output.
1296 Wed Jun 26 14:51:40 EDT 1991
1298 eval.c Added range checks on assignment.
1299 m2-exp.y Added the grammar for sets to the language. Currently,
1300 these do not do anything except print an error message.
1302 Wed Jun 26 17:01:04 EDT 1991
1304 m2-exp.y Added the ability for parse_number() to parse negative
1305 numbers. A global flag is set upon encountering a unary
1306 minus. This was done to make, for example, 1 parse as a
1307 CARDINAL, and not as an integer, per Wirth's examples in
1308 Programming in Modula-2 ed.4.
1309 valprint.c Added support for "set radix 2" by then setting
1310 output_format to 't'.
1311 eval.c Implemented range checking on subrange types. Added calls
1312 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
1313 Implemented MIN and MAX for ennumerated types. The
1314 minimum value of an ennumerated type is defined by Wirth
1315 as the first identifier, and the maximum as the last.
1316 m2-exp.y Made octal numbers ending with "B" be characters and those
1317 ending with "C" be numbers, per Wirth's book. (p. 34)
1319 Thu Jun 27 14:11:52 EDT 1991
1321 stack.c select_frame() now only sets working_lang, it does not
1322 notify the user. If working_mode is language_manual, then
1323 a warning is issued once.
1324 main.c At the end of each call to execute_command(), working_lang
1325 is checked against the local static (enum language)
1326 current. If they differ and working_mode is
1327 language_auto, the new settings of language, type and
1328 range checking are printed out.
1329 stack.c Modified frame_info() to include the language of the
1330 current frame in the output of "info frame".
1331 language.[ch] Added the function language_str() which returns the name
1332 of the current language.
1334 Fri Jun 28 15:33:14 EDT 1991
1336 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
1337 the language. INCL and DECL currently cause an error,
1338 since sets are not implemented yet. INC and DEC are
1339 implemented as PREINCREMENT/PREDECREMENT with one
1340 argument, and as ASSIGN_MODIFY with two arguments.
1341 eval.c Added type checking to the above cases.
1342 value.h Added not_lval_constant to the lval_type ennumerated type.
1343 not_lval_constant means that the value is a constant
1344 value; that is 3 or 'a' or TRUE, not as in a constant
1345 identifier. This is used to help coerce numbers such as 3
1346 to either signed or unsigned numbers.
1347 valops.c Added the function value_coerce_constants() which coerces
1348 constant integers as following: if one is a constant and
1349 the other is not, the constant's type is set to the type
1350 of the other argument. If both are constants and one is
1351 signed, the other is converted to a signed constant.
1353 Sat Jun 29 17:26:29 EDT 1991
1355 valarith.c Added a better range checker. It now checks range
1356 (successfully) on integral operations [+-] (signed and
1357 unsigned) for any C sized type. Still does not work well
1358 for multiplication.)
1359 int_in_size() returns an integer that is coerced to fit into
1360 specified number of bytes.
1362 Mon Jul 1 13:04:14 EDT 1991
1364 language.[ch] Added the function binop_result_type(), which returns the
1365 builtin (struct type *) type that would be the result of a
1366 binop on the two values V1 and V2.
1368 Wed Jul 3 19:22:53 EDT 1991
1370 source.c Extended source_info() to include the source language in
1371 the output from "info source".
1373 Fri Jul 5 13:48:52 EDT 1991
1375 utils.c Moved the support functions for the GDB set/show commands
1376 dealing with language into language.c.
1377 language.c Added the function language_info(), which displays info
1378 about the current working language, type and range check
1379 settings. Called via the GDB command "info language".
1380 Added an initialization routine _initialize_language(),
1381 that sets defaults for the language, type and range
1382 variables and sets up the new GDB commands.
1383 main.c Language setup moved to language.c.
1386 Mon Jul 8 10:10:22 EDT 1991
1388 valarith.c Debugged the range checker for arithmetic. Still does not
1389 work for multiplication very well.
1391 Mon Jul 8 12:40:37 EDT 1991
1393 language.[ch] Added the function value_true() which returns non-zero if
1394 its argument represents a boolean true value.
1395 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1396 check the truth of an expression.
1398 Thu Jul 11 12:51:34 EDT 1991
1400 language.[ch] Added the predicate structured_type(), which returns
1401 non-zero if the argument is a structured type.
1402 Added the predicate pointer_type(), which returns non-zero
1403 if the argument is a pointer type.
1404 eval.c Added the ability to do addition and substraction on
1405 pointers and integers. This case simply bypasses the
1408 Thu Jul 11 14:41:42 EDT 1991
1411 Added the symbol N_DEFD (0x4a) which is a definition
1412 module dependency that is used by the GNU Modula-2
1413 compiler and the linker. It is not important to GDB,
1414 except that [dbx|coff|mips]read.c should ignore these
1417 Fri Jul 12 16:07:00 EDT 1991
1419 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1420 0 in val_print(). Also added statements to the else part
1421 to coerce type (argument to val_print) to a pointer type
1422 if it is an "array of unspecified length".
1423 valops.c Added the function value_m2_string(), which returns a
1424 (value) value which is a constant string, whose type is
1425 (ARRAY [0..n] OF CHAR). The length field of the type
1426 structure is set to zero, so it will be interpreted as an
1427 "array of unspecified length".
1428 stack.c Moved the language/frame mismatch check to
1429 main.c:execute_command().
1430 main.c The working language is recorded each time
1431 execute_command() is executed. If working lang has
1432 changed during its execution, then the new
1433 language/type/range info is printed out for the user. If
1434 the working language does not match the language of the
1435 frame, a warning is issued.
1437 Sat Jul 13 16:16:39 EDT 1991
1439 eval.c Moved all the type-checking stuff for operators to
1440 language.[ch] language.c. This is so we can keep language-specific
1441 stuff (like for what type operators are defined) in
1443 language.[ch] Added the function binop_type_check(), which checks to see
1444 if its two (value) arguments are type-compatible with its
1445 opcode argument. The opcode should represent an operation
1446 involving an operator. Also added the macro function
1447 unop_type_check, which calls binop_type_check with a
1448 NULL second argument.
1449 expprint.c Added Modula-2 operators to the op_print_tab, so info
1450 expression.h break works correctly. Also added "op_string", which
1451 returns the string corresponding to the (enum exp_opcode)
1452 opcode that is its argument.
1455 Sat Jul 13 18:26:18 EDT 1991
1457 coffread.c Added code to record the type of function arguments with
1458 each paricular function. Code is very similar to that
1460 dbxread.c Moved add_param_to_type() to symtab.c
1461 symtab.[ch] Added function add_param_to_type() from dbxread.c
1463 *** NOTE: The above additions have not been tested.
1465 Mon Jul 15 12:50:47 EDT 1991
1467 langauge.[ch] Added the functions type_error and range_error, which work
1468 like error() except if the type/range mode is set to
1469 *_mode_warn, then they do not do a return_to_top_level(),
1470 but merely print a warning.
1471 Also changed [set|show]_[type|range]_command() to support
1472 the new "warn" feature.
1474 Thu Jul 18 17:50:54 EDT 1991
1476 mipsread.c Added code to record the type of function arguments with
1477 each particular function. Code is very similar to that
1480 *** NOTE: The above additions have not been tested.
1482 Fri Jul 19 11:19:10 EDT 1991
1484 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1485 UMIN_OF_SIZE, which when given a size of a numeric type,
1486 return the maximum and minimum value it can hold. UMAX...
1487 and UMIN... return the result for unsigned types.
1488 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1489 struct types. They call above macros.
1490 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1491 avoid a name conlict with the above.
1492 c-exp.y Added range checking on numeric constants in
1493 parse_number() for completeness.
1494 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1495 return 0 if working_lang is not language_c.
1497 Thu Aug 8 14:17:22 EDT 1991
1501 breakpoint.c Documentation strings of some commands changed to
1502 eliminate the references to the C language where
1505 Tue Aug 13 15:48:03 EDT 1991
1507 m2-exp.y Added qualified identifiers to the grammar. The semantics
1508 are slightly different from those of the GDB operator ::
1510 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1511 type_exp, where type_exp is any valid type expression.
1513 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1514 printcmd.c Modified ptype_command() so it actually parses the input
1515 (necessary for type expressions with scope qualifiers).
1516 Added the function ptype_eval() which expects an
1517 expression composed of one OP_TYPE element.
1518 *.[ch] Replaced all occurences of parse_c_expression with
1520 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1522 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1524 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1526 Small fixes from Peter Schauer:
1528 * infrun.c (child_attach): Lint.
1529 * solib.c (find_solib): Handle shared libs version 2.
1531 Small fixes from David Wood:
1533 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1537 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1538 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1540 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1541 chars_per_line is at maximum (user typed `set width 0'). Fix
1542 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1544 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1546 * coredep.c: include ptrace.h where necessary.
1547 * mipsread.c(parse_lines): fix unsigned char problem that was
1548 messing up line numbers on SGI's and possibly other MIPS based
1550 * infrun.c (child_create_inferior): use better test to check
1551 return val from setpgrp().
1552 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1553 for sgi/irix support.
1555 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1557 * mipsread.c (parse_symbol): Put non-static procedures
1558 in the global block.
1560 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1562 Patch together `text_start' and `text_end' for 29K port.
1564 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1565 variables and set them based on the exec file.
1566 * am29k-tdep.c: declare text_start.
1567 * valops.c (call_function_by_hand): declare text_end.
1569 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1570 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1571 because machines that do this will also have to know to
1572 set NEED_TEXT_START_END. Besides, it was a redundant way to
1574 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1575 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1576 NEED_TEXT_START_END.
1578 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1580 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1582 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1583 Pass MUNCH_DEFINE to munch whenever we run it.
1584 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1585 format string; use 0x%x instead.
1586 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1587 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1588 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1589 * inflow.c: Handle `short' process group IDs.
1590 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1591 and check for ptrace errors.
1592 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1593 (coff_symfile_init): Initialize text_bfd_scnum.
1594 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1595 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1596 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1597 Merge target arm case with other "easy" cases. Add target
1598 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1599 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1601 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1602 * munch: Cope with RT/PC putting fns in data segment.
1603 Restore ability to override `nm' by specifying MUNCH_NM.
1604 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1605 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1606 and remote-adapt. Remove encapsulated coff #define's (the
1607 support should go in BFD, and gdb shouldn't know or care).
1608 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1609 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1610 * tm-29k.h: Update BADMAG (though it should go away).
1611 Allow the register definitions to be overridden in another
1612 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1613 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1614 DUMMY_SAVE_GR96, for handling kernel calling conventions
1615 that use GR64+ rather than GR96+.
1616 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1617 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1618 overrides various things.
1620 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1621 child_attach does, making a clean stop in the newly attached
1623 * remote-eb.c: Lint.
1625 * coffread.c: Make coffread independent of any particular
1626 variant of COFF. Avoid #include-ing any particular one except
1627 internalcoff.h. BFD now passes key values for symbol reading
1628 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1629 and the symbol masks and shifts); use them.
1630 Remove obsolete end_of_text_addr.
1632 * exec.c: Remove unused include files.
1634 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1636 * Makefile.in (documentation targets): Pass $(M4).
1637 Bugfix from eggert@twinsun.com (Paul Eggert).
1639 * stack.c (down_silently_command): Check for stack existence.
1641 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1643 * Makefile.in (VERSION): Update to 4.0.3.
1645 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1647 * core.c (core_file_command): Print frame at coredump with
1648 its level number, by calling print_stack_frame.
1649 * frame.h: Add selected_frame_level, print_stack_frame.
1650 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1651 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1652 Change print_sel_frame and print_selected_frame callers to
1655 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1656 * symfile.c (free_named_symtabs): Ditto.
1657 * main.c (main): wrap_here needs an arg.
1658 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1659 (solib_add): Avoid noise.
1660 (solib_create_inferior_hook): Lint.
1661 (sharedlibrary_command): Move dont_repeat to here.
1662 * utils.c (error): Call wrap_here to force buffered output.
1664 Small patches from Peter Schauer:
1666 * coffread.c (start_symtab): Free any existing line_vector before
1668 (read_coff_symtab): Ditto for type_vector.
1670 * source.c (lines_to_list): New variable, replacing function.
1671 (all uses): Use as variable.
1672 (_initialize_source): Add 'set listsize' and 'show listsize'.
1673 * utils.c (lines_to_list): Remove function.
1674 * stack.c (print_frame_info): Use as variable.
1675 * defs.h (lines_to_list): Remove declaration.
1677 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1679 * breakpoint.c (insert_breakpoints): Restore warning about
1680 the program might be running in another process, but only for
1681 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1682 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1684 * utils.c (error): if error_pre_print is set, print the string
1686 * main.c (main, print_gnu_advertisement, print_gdb_version):
1687 Reformat legalese so it always prints, but acts as an "I'm here"
1688 message while symbols are being read. If any errors occur,
1689 print a few newlines to set off the message and start it at the
1690 left margin. Remove mention of "help" command, and don't yak
1691 about symbol reading.
1692 (catch_errors): Error string is now printed first in case of
1694 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1695 suggest the "help" command.
1697 * Makefile.in (VERSION): Set to 4.0.2.
1699 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1701 * .gdbinit: Remove useless "rr" command. Set complaints
1702 to 1 for people debugging gdb.
1704 * breakpoint.c, remote-vx.c: Reword strings printed by
1705 catch_errors callers.
1707 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1709 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1710 (Fix from kenc@viewlogic.com.)
1712 Fix some infrastructure to be able to cope with host and target
1713 machines with different sized basic types (ints, ptrs, etc).
1714 (Idea from pierre@la.tce.com (Pierre Willard).)
1716 * values.c (value_from_longest): Rename from value_from_long.
1717 Handle pointer types as well as integers, so that targets with
1718 different pointer sizes from the host can be accomodated.
1719 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1720 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1721 uses of value_from_long to value_from_longest.
1722 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1723 the correct pointer type to value_from_long{est}.
1725 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1727 * remote-vx.c: Remove obsolete code for calling functions via
1728 vxworks kludge interface (it referenced value_from_long).
1730 * valops.c (value_string): Find malloc with lookup_misc_func, not
1733 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1735 Make writing to files work properly. (Fixes to BFD are also needed.)
1737 * core.c (core_open): Open file ourselves, read or r/w, depending on
1738 write_files. Use bfd_fdopenr.
1739 * gdbcore.h (write_files): New variable.
1740 * exec.c (write_files): Define variable, add set&show for it.
1741 (exec_file_command): Use write_files to open for read or r/write.
1743 Make shared library reading happen automatically. These changes
1744 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1746 * inferior.h (stop_soon_quietly): Add to exported variables.
1747 * infrun.c (child_create_inferior): call solib hook, if defined.
1748 (child_attach): call solib hook, if defined.
1749 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1750 (find_solib): Use lookup_misc_func rather than hand-rolled.
1751 (symbol_add_stub): New stub for catch_errors.
1752 (solib_add): Avoid output if !from_tty. Catch errors rather
1753 than just calling symbol_file_add and bombing.
1754 (solib_create_inferior_hook): Interface with the target process
1755 to let it read and alloc shared libs, then figure out what it did.
1757 * core.c (validate_files): Fix typo, soften warning.
1758 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1760 * utils.c (fputs_demangled): Avoid duplicate printing if
1761 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1763 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1764 (Fix from pierre@la.tce.com (Pierre Willard).)
1766 * main.c (catch_errors): Change argument to a char * from an int,
1767 since a char * can point to a struct full of glop, but an int
1768 is not guaranteed to be able to hold a pointer.
1769 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1770 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1771 * core.c (core_open, solib_add_stub): Adapt.
1772 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1774 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1776 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1777 by adding .NOEXPORT target.
1779 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1783 * Makefile.in (VERSION): Roll to 4.0.
1784 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1786 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1788 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1791 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1794 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1796 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1797 reflect above name change
1799 * WHATS.NEW: correct pointer to refcard.
1801 * doc/gdb.texinfo: update New Features, Installing
1803 * doc/gdbint.texinfo: add short description of configure +template
1805 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1807 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1809 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1811 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1812 tar file, add dependencies for referenced doc files.
1814 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1816 * coffread.c, symfile.c, stack.c: saberized.
1818 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1820 * doc/refcard.tex: permuted Essential Commands sec
1822 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1824 set/show symbol-reloading
1825 default set complaints 0
1827 RET-repeat disabled after prompted long displays
1828 processID (attach) interpretation of 2nd GDB cmdline arg
1830 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1832 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1833 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1834 breakpoint.c, main.c: lint.
1836 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1838 Install new configuration scheme for GDB and friends.
1840 * config.sub: Translate ordinary names to three-part names.
1841 * configure: Use three-part names internally.
1842 * configure.in: Translate three-part names to filenames.
1844 * README, WHATS.NEW: Update for gdb-4.0.
1845 * Makefile.in: Roll VERSION to 3.99.
1847 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1849 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1850 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1851 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1852 to single structures rather than arrays; when passing
1853 their address, use &. This avoids trouble with bdead compilers.
1854 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1855 instead. This avoids portability headaches.
1856 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1858 * source.c (open_source_file): Avoid ANSI const bdeath by
1859 skipping declaration and then casting result value.
1860 * tm-hp300bsd.h: Clarify comment.
1861 * utils.c (strstr): Result is const char *; ANSI bdeath.
1862 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1863 since system include file defines it differently from "defs.h",
1864 though the two are equivalent for our purposes.
1865 * tconfig/hp300bsd: Add m68k-tdep.o.
1867 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1869 * tconfig/sun*4: Remove warnings about system assembler.
1871 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1873 * mcheck.c: Avoid warning about undeclared abort fn.
1874 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1875 it causes recursive calls to error() when used in cleanups.
1876 To do so requires that we make it a function, so we do.
1877 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1878 * utils.c (do_cleanups): Remove the current cleanup from the
1879 chain *before* calling it, in case error() is called from it.
1880 The result won't be pretty, but won't be an infinite loop either.
1882 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1884 * dbxread.c (read_struct_type): Grok anon structs for C++.
1885 (vb_name, vptr_name): Null terminate these strings.
1887 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1889 Minor bug fixes from BSD Net2 gdb:
1891 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1892 returns 0, there is no previous frame.
1893 * breakpoint.c (commands_command): If !from_tty, don't call
1894 input_from_terminal_p().
1895 * dbxread.c (record_misc_function): Speed up slightly.
1896 (compare_psymbols): Ditto.
1897 * infcmd.c (do_registers_info): Take a second argument to
1898 determine whether to print float registers. "info registers"
1899 does not do so anymore. "info all-registers" does, now.
1900 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1902 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1903 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1907 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1908 executing_breakpoint_commands if we are interrupted by error.
1909 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1910 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1911 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1912 catch_errors() so we can setup the frame regardless of whether
1913 the shared libs work.
1914 * ieee-float.c (double_to_ieee_extended): Get exponent from
1915 right place in little-endian systems. From John Carey.
1917 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1919 * main.c: Remove unused terminating_signals and catch_termination().
1920 (long_options): Terminate with a zero element.
1921 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1922 (gdb_readline): Make call-compatible with readline.
1923 (init_signals): Improve comments re vfork vs. signal.
1925 * utils.c (prompt_for_continue): Use new gdb_readline().
1926 If we prompt for continuation, we don't let CR repeat the previous
1927 command, once we get back to a prompt. It's too easy to keep
1928 hitting CR, expecting "--more--" prompts, and have some long
1929 command start repeating on you.
1931 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1933 * blockframe.c (frameless_look_for_prologue): Speed up by
1934 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1935 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1936 Define two variants, one faster.
1937 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1938 and return zero, rather than giving an error.
1939 (setup_arbitrary_frame): Initialize the PC in the new frame.
1940 (skip_prologue): Add a second arg saying whether we're just
1941 checking for a frameless function or not.
1943 * core.c (core_open, core_close, core_xfer_memory): Move
1944 section table pointers and bfd* into the target_ops.
1945 (core_open): Allow errors in shared lib reading, etc.
1946 (core_files_info): Describe shared library sections.
1948 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1949 exec_files_info, set_section_command): Move section table
1950 pointers and bfd* into the target_ops.
1951 (add_to_section_table): Add BFD to section table.
1953 * target.c (target_xfer_memory, target_info): Pass target to
1954 xfer_memory and target_info functions.
1957 * gdbcore.h: Move struct section_table.
1958 * target.h: New home of struct section_table.
1960 * solib.c (solib_add): New argument is the target_ops whose
1961 section list is to be added to, if any. Reallocate the
1962 sections in that target to add any that come from shared libs.
1963 (throughout) so_sections renamed to sections.
1964 (solib_xfer_memory): Deleted.
1965 * tm-sunos.h (SOLIB_ADD): Add target argument.
1966 (SOLIB_XFER_MEMORY): Delete.
1968 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1969 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1970 from target_ops. It's the same on all targets. Add two section
1971 pointers to target_ops.
1973 * stack.c (find_relative_frame): Dump ancient algorithm for
1974 "down", just use handy "next" pointers.
1975 (frame_command): Don't error if there is no stack; let user
1978 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1979 modifies static state in the parent process; new_tty itself
1980 runs in the child and modifies the child's file descriptors
1981 to match the saved static state.
1982 * infrun.c (child_create_inferior): Call new_tty_prefork,
1985 * infptrace.c (child_xfer_memory): Add ignored target arg.
1986 * remote-eb.c (eb_xfer_inferior_memory): ''
1987 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1988 * remote-vx.c (vx_xfer_memory): ''
1989 * remote.c (remote_xfer_memory): ''. Rename from
1990 remote_xfer_inferior_memory.
1992 * main.c (main): Only try to attach "corefile" argument if
1993 it starts with a digit.
1995 * symfile.c (symbol_reloading): New "set/show" variable.
1996 (symbol_file_add): Shorten message about symbol reading.
1997 (add_symbol_file_command): Merge with add_syms_addr_command,
1998 since this should work on all targets now.
1999 (stop_whining): Default to zero, to shut up complaints
2000 about bad symbol tables on many systems.
2001 (free_named_symtabs): Just exit unless symbol_reloading.
2003 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
2004 and add comment explaining shared library screw.
2006 * source.c: #if defined => #ifdef.
2008 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2010 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
2012 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2014 * doc/rdl-apps.texinfo: provide default readline-appendix finder
2015 (doc/Makefile knows how to make one for local config)
2017 * Makefile.in: use doc/Makefile for doc targets
2019 * doc/Makefile: GDB documentation now has its own Makefile
2020 doc/refcard.tex: renamed from "gdbrc.tex"
2021 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
2022 doc/gdbint.texinfo: add markup in "Cleanups" chapter
2025 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2027 * values.c (baseclass_addr): When reading target memory, use the
2028 length of the basetype, not the upper type. We've only malloc'd
2029 enough space for the basetype, leading to errors in free().
2031 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
2032 ends up as a function specially, since we know the actual type of
2033 the pointed-to address. This (somewhat) fixes display of
2034 expressions that include misc_function_vector names. Try `cond 1
2035 !strcmp("a","b")' then `i b'.
2037 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
2038 The child can be proceeded from inside wait_for_inferior in
2039 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
2040 getting skipped in that case.
2042 * expprint.c (print_subexp): Use filtered output, since the
2043 subroutines we call use it, otherwise the output is horribly
2044 mangled, since output of wrappable stuff comes out late.
2046 * Makefile.in: Bump VERSION to 3.98.1
2048 * infrun.c (child_create_process): Use execlp to find the
2049 shell to exec our target program. This requires some fiddling
2050 with `environ' since there is no execlpe().
2052 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2054 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
2055 Minor rearrangement of refcard permits two new make targets--
2056 gdbrc.dvi DVI output for refcard, using CM fonts
2057 gdbrc.ps PostScript refcard, using PS fonts
2059 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2063 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
2064 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
2066 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2068 * doc/gdb.texinfo: last changes for release.
2069 Minor typo and formatting fixes; incorporated most fixes remaining from
2070 filed mail commenting on earlier drafts.
2072 Added warnings: pipes don't work in run command;
2073 conditions are converse of assertions;
2074 step over fn without debug info goes to next fn;
2075 vars may have "wrong" values near fn entrance, exit
2077 Added example from Kingston on printing repeated nonadjacent values
2079 Added explicit mention that in Emacs gdb mode C-c and C-z are like
2080 shell mode for signals
2082 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
2083 doesn't sound so much like its parent "Stopping and Continuing"; also
2084 moved entries on continue to top of section, so they don't get lost.
2086 Improved installation directions in appendix, added manual formatting
2089 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2091 * configure.in: Remove xm.h and tm.h even if we aren't linking
2092 new ones, so "./configure sun4; ./configure none" does the right
2093 thing. Assume that alldeps.mak and depend are already built in
2094 srcdir, and avoid running "make" (particularly "make depend",
2095 which involves "gcc") from inside configure. Build Makefile
2096 directly rather than building Makefile.conf first.
2097 * configure: Regenerate with above changes.
2098 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
2099 to 3.98. Revise gdb.tar.Z procedure to produce a file
2100 called gdb-$(VERSION).tar.Z but which unpacks into a
2101 directory called "gdb". Move non-source files out of
2102 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
2103 (depend): Don't try to do "gcc expread.y".
2104 (expread.o): Update dependencies by hand.
2106 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2109 Fixed a variety of small typos that prevented info from formatting
2110 cleanly; altered too-long heading for GPL Appendix, as discussed
2111 w/RMS; Changed date on cover to July 91.
2113 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2116 (1) Applied some fixes due to comments from Larry Breed (easier ones
2117 through chapsec 5.2)
2118 (2) Eliminated use of @footnote---had my doubts about it anyways, and
2119 it's broken in latest texinfo
2120 (3) Introduced *some* use of [] for optional arguments, where
2121 explanation is not simpler by listing cmd w arg and cmd w/out arg
2122 separately. Still not using @deffn.
2123 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
2124 couple of headings are too long. Need patches to texinfo or revision
2127 * Partial update to README (which still needs work for this
2128 release!): (1) use of configure corrected for new script,
2129 (2) "make gdb.dvi" and "make gdb.info" mentioned.
2131 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
2133 * symtab.c (lookup_symbol): Don't complain right off about
2134 no debug symbols; use the misc function vector first.
2135 (list_symbols): Use misc function vector to find symbols
2136 that don't have debug info, and print them.
2137 (find_pc_symtab): Temporarily avoid fatal() when psymtab
2138 PC range doesn't match symtab PC range, as it does on the
2139 MIPS because our symtab reading isn't perfect.
2141 * dbxread.c (dbx_symfile_read): Make warning about
2142 "no debug symbols" slightly nicer.
2144 * source.c (select_source_symtab): If "main" symbol exists,
2145 but decode_line_spec can't find line info, don't just return
2146 a zero; try other source symtabs or give an error.
2148 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
2149 their low addresses first, then rip through fixing high addrs.
2151 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
2152 <runene@ifi.uio.no>.
2153 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
2155 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2157 * Minor, mostly mechanical, cleanup of doc subdir for clean
2158 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
2159 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
2161 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
2163 Mostly MIPS and general symbol-reading fixups.
2165 * doc/gdbint.texinfo: Add documentation on symbol-reading
2168 * mipsread.c: Remove kludges around #include "ecoff.h".
2169 Remove redefinitions of a_magic, etc, no longer used.
2170 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
2171 Fix global overview comments to match symfile.c protocol.
2172 (mipscoff_new_init): Eliminate cur_hdr if we have one.
2173 (mipscoff_symfile_read): Eliminate unused code. Avoid
2174 sorting all the symtabs, when all we have read here is psymtabs.
2175 The symtabs are sorted as they are created anyway. Tell
2176 condense_misc_bunches whether we're mainline.
2177 (psymtab_to_symtab_1): Pass filename when recursing, to make
2178 stack trace more informative.
2179 (parse_partial_symbols): Assume cur_hdr as argument.
2180 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
2181 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
2182 the TYPE_NAME of char *, since that's done in symfile.c.
2183 (free_numargs, parse_symbol, add_symbol, add_block,
2184 shrink_linetable): Declare these fns void.
2185 (upgrade_type): Convert tree of if's to switch. Clean up
2186 bogus "off == 0" handling with a complaint. Avoid setting
2187 field bitpos and bitsize of array with lower and upper bounds.
2188 Check specified bitsize of elements against their actual type's
2189 bitsize, and complain if different. Complain about unknown
2191 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
2192 (psymtab_to_symtab_1): Print names of subsidiary files that
2193 are being read in. FIXME, we read far too many files. This code
2194 is not the problem, the problem is in parse_fdr where the psymtabs
2196 (cross_ref): Result should indicate that we used one aux entry
2197 normally, or two if we encountered a "next" entry. This used
2198 to leave the caller pointing at the wrong aux entry.
2199 (add_symbol): If overflowed cur_block, reallocate it larger,
2200 chase all pointers to it, and complain(), rather than clobber memory.
2201 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
2202 (new_field): Only allocate one field initially, not two.
2203 Pull ++ out of macro argument. Simplify.
2204 (_initialize_mipsread): Avoid initialization of importd
2205 global_psymbols and static_psymbols.
2207 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
2208 to properly set pst->symtab; avoid searching for it.
2209 (symfile_fns): Improve comments, add a FIXME.
2210 * dbxread.c: Update comments to reflect symfile protocol.
2211 (read_ofile_symtab, end_symtab): Return the symtab.
2212 (psymtab_to_symtab_1): Set pst->symtab.
2214 * coffread.c (coff_symfile_read): tell condense_misc_bunches
2215 whether we're mainline.
2217 * symfile.h (sym_fns): Remove unused sym_discard member.
2218 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
2220 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
2221 the environment variable is not.
2222 * infcmd.c (finish_command): Use filtered printfs.
2223 * cplus-dem.c: Add struct tags to a few unnamed structs.
2224 * valops.c (value_coerce_array): Improve comments.
2225 * valprint.c (type_print_varspec_suffix): Print array size only
2226 if greater than zero.
2227 * m88k-tdep.c: Shift some lines left by one space, that had
2228 apparently been trashed at some point.
2229 * TODO: More things to do, a few got done.
2231 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2233 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
2234 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
2236 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
2237 * expread.y, findvar.c, symmisc.c: Ditto.
2238 * printcmd.c (address_info): Update printed forms of LOC_
2239 symbols. Elim LOC_EXTERNAL.
2240 (print_frame_args): Keep track of param stack offsets before
2241 re-looking up to find the local register param is kept in.
2243 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
2244 Further integration of mipsread into gdb. Eliminate unused
2245 routines, duplicate declarations. Handle static symbols in
2246 psymtabs as well as external symbols. When reading symtabs,
2247 insert symbols into the correct block (global, static, or a local
2249 (read_mips_symtab, parse_partial_symbols): Don't pass useless
2251 (mipscoff_symfile_read): Don't call select_source_symtab.
2252 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
2253 rather than SYMBOL_VALUE.
2254 (parse_external): Comment clobbering of top_stack.
2255 (parse_partial_symbols): Update comments. Allocate and parse
2256 static symbols as well as external symbols. FIXME, enum values
2257 are not handled in this pass, but should be. Inline new_psymbol.
2258 Use SYMBOL_VALUE_ADDRESS.
2259 (psymtab_to_symtab_1): Read symbols into global static block
2260 by default (until enter some function's local block context).
2261 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
2262 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
2264 * source.c (select_source_symtab): Select a source symtab
2265 from either the symtabs or, failing that, the psymtabs.
2266 (list_command): Update error message.
2267 (forward_search_command, reverse_search_command): Use getc, not
2268 fgetc, for speed. FIXME, add comment about buffers that die if
2269 overrun by long line.
2271 * values.c (unpack_field_as_long, modify_field): Avoid shifting
2272 by an entire word, which is not portable, if we have a 32-bit
2273 field. (Code in dbxread.c already turns such bitfields, if
2274 aligned, into ordinary ints, but fixing this will help for other
2275 symbol formats and for future changes.)
2276 * core.c (core_open): Handle ANSI const brain death.
2277 * utils.c (vprintf): Fix varargs typo.
2279 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2281 * findvar.c (find_var_value): Handle &function better.
2282 * TODO: Document work needed on &fn and &array.
2283 * printcmd.c (print_address_symbolic): New arg is the prefix
2284 to print if a name is printed.
2285 (print_address_demangle): Honor "set print address" now.
2286 Use new arg above to improve spacing of output.
2287 * valprint.c (val_print): When printing function pointers,
2288 print symbolic form too.
2289 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
2291 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2293 * core.c (memory_error): Reword error msg to mislead less.
2295 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
2297 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
2298 parse_partial_symbols): Use newer BFD internals (external_filehdr
2299 and external_aouthdr), byte-swap the fields that we care about
2300 before using them, and make the file header data local to
2301 read_the_mips_symtab rather than global.
2303 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
2305 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
2306 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
2308 * main.c (command_line_input): Flush stdout and stderr
2309 before every call to readline. This reportedly fixes a bug
2310 that comes up in Sys V running emacs-gdb and/or xxgdb,
2311 when stdin/out are pipes or sockets.
2313 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2315 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
2316 Avoid declaring Makefile dependencies, because GNU Make stupidly
2317 tries to update it if we do.
2319 * coffread.c: Revise for minor changes to bfd internal coff
2322 * configure: If -template= is given a relative path, make it
2323 absolute before recurring in subdirectories.
2325 * configure, configure.in, Makefile.in: Install "configure" script
2326 as replacement for config.gdb.
2327 * config.gdb, Makefile.dist, Makefile.sdir: Remove
2328 * README: Update for configure, mostly. FIXME.
2330 * Add dec3100 as equivalent to littlemips. Indicate in all host &
2331 target config files that they are for the host. When the lines
2332 get copied into the Makefile, this makes it more obvious what's
2335 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2337 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
2338 tabs, which end up in the disassembler output inadvertently.
2340 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2342 Make it compile cleanly in an ANSI GCC2 environment.
2344 * blockframe.c: <stdio.h>
2345 * cplus-dem.c: free takes a void *, ifdef __STDC__
2346 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
2348 * defs.h (alloca): Avoid doing anything if alloca already def'd.
2349 * stddef.h, stdlib.h: Remove these files.
2350 * symtab.c: Avoid declaring qsort, close.
2351 * symfile.c: Avoid declaring close.
2352 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
2353 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
2355 Assorted other changes.
2356 * dbxread.c: include "libaout.h", not "liba.out.h".
2357 * printcmd.c (print_frame_args): Set recurse properly for
2358 indentation of struct and array parameters.
2359 * valops.c (value_cast): Allow cast to void.
2360 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2361 single_step() in a target-independent fashion.
2362 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2363 set up to be ready to continue. This makes us target independent.
2364 * infptrace.c (child_resume): Remove call to single_step; now
2365 can single step a SPARC target of any kind.
2367 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2369 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2370 docn into separate sections---basically chapters, plus two loose
2371 pieces that can be configured to go in different places. This
2372 allows GNU m4 to preprocess the manual without coredumping.
2374 * Makefile.dist: tell TeX where to find texinfo.
2376 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2378 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2379 the new target "rdl-apps.texinfo" which captures the Makefile
2380 variable that records where to find the Readline libraries.
2382 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2384 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
2385 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
2386 * defs.h (const, volatile): Only define if not already defined.
2387 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2389 * README: Update for release 3.95.
2390 * config.gdb: Don't create readline dir in subdir builds.
2391 * main.c: Include with "..." form for non-system include files,
2392 so "gcc -MM" for "make depend" works.
2393 Include readline files with "...h" rather than <readline/...h>.
2394 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2396 * coffread.c: Undo minor damage done by Rich Pixley. Use
2397 different internal and external representations of COFF
2398 data structures. Use new BFD routines for swapping them in and
2400 * symfile.c (free_named_symtabs): Avoid freeing file names that
2401 are null or empty. Old i960 tools seem to produce files that
2402 claim to have empty names, causing each successive file read
2403 to blow away the previous one.
2404 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2405 Move deferred_stores to top of file, but don't separate its
2406 #define's from its variable. Add commentary.
2407 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2408 favor of keeping the (working) config.gdb. Move readline
2411 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2413 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2415 * infptrace.c (fetch_registers): no result, since now void.
2416 * tconfig/news: target depends on m68k-tdep too.
2418 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2420 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2423 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2424 applied various small fixes due to or inspired by RMS comments
2426 * doc/gdb.texinfo: finished using all RMS comments, save those for
2427 appendices on readline and cmd history (which are in other source
2430 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2432 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2433 chapter 9; (2) documented 'break' command's menu mode for
2434 overloaded names, in response to hgs problem report C++ p-31
2436 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2438 * doc/gdb.texinfo: (1) better introductory example; (2) more
2439 consistent use of @code, @samp, @file, @kbd throughout; small
2440 cleanups to first three nodes; (3) new "Contributors" node;
2441 (4) Appendix, Renamed Commands; (5) divert specialized startup
2442 instructions to "Targets" chapter for generic manuals, while
2443 leaving them up front for manuals specific to specialized
2444 environments; (6) apply fixes from RMS comments through chapter 4.
2446 * pretex.m4: modify explanatory text slightly (and redefine
2447 "regexp") to keep GNU m4 from complaining. (It still crashes
2448 later, but one step at a time...)
2450 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2452 * readline/readline.c (update_line): Avoid dereferencing a pointer
2453 before comparing it to its bounds. Saber caught this.
2454 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2455 and only set PC if tgetstr returned non-null. Saber caught this.

2459 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2460 stuff for config manual) here where it counts; updated
2461 to use new subdir structure (gdb/doc/).
2463 * Makefile: generated from above via
2467 * gdbint.texinfo: added instructions on generating gdb.info* files
2468 locally for release. These are ordinary info
2469 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2470 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2471 to generate these, so we distribute them already formatted.
2473 * gdb.texinfo: included full Info node and menu crud (as generated
2474 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2476 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2477 put in comments-for-future gdb.info target (one day makeinfo will
2480 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2482 * gdb.texinfo: Updated to include new or old undocumented
2483 commands, at least the following (perhaps some others I forgot to
2484 record): info f, info float, info path, info program, info s, info
2485 set, info source, info terminal, info types, info user, set/show
2487 Also covered all recent GDB command renames for v4.
2489 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2491 * mipsread.c: Rather than keeping count of how many symtabs
2492 and psymtabs we have, for sorting purposes, count them when
2493 we need to sort. This fixes bug in rereading of symbol tables.
2495 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)

2512 symtab.h, target.c, target.h: Lint.
2513 * core.c: setup and select frame after reading shared libs,
2514 else reading shared libs will clobber them. Lint.
2515 * utils.c (error): Force out any buffered wrap text.
2517 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2519 * remote.c: Remove decls of memory_insert_breakpoint
2520 and memory_remove_breakpoint, no longer used. (Suggestion of
2523 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2524 to make it easier to interface to "configure"'d libraries.
2526 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2528 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as

2920 before returning locals or slocals.
2922 * i386-tdep.c (i386_follow_jump): Do not add data16 to pos in

2954 tm-sun3.h: Define TARGET_SUN3.
2956 * utils.c: Use CPLUS_MARKER not '$'.
2958 * cplus-dem.c: Use CPLUS_MARKER not '$'. If CPLUS_MARKER isn't
2959 defined, define it to '$'.
2961 * arm-opcode.h: New file (same contents as before; it had
2962 just been left out of the distribution for a long time).
2964 * tm-68k.h: Put declaration of ext_format_68881 outside the macros.
2966 * main.c: New HAVE_SIGSETMASK #ifdefs.

2990 * mips-xdep.c (fetch_core_registers): #if 0 out the whole function.
2992 * Move read_memory_nobpt from mem-break.c to breakpoint.c.

3032 * inftarg.c (child_open), remote-vx{,.68}.c (vx_proc_open):
3033 New function to give correct error message.
3035 Thu Apr 11 17:19:41 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
3037 * target.h: Add to_doc and target_preopen.
3038 target.c: Add target_preopen and target_command.
3040 (add_target): Call add_cmd and mess with targetlist->doc.
3041 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
3042 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.
3043 Call target_preopen from open routine.

3062 Thu Apr 18 18:08:30 1991 John Gilmore (gnu at cygint.cygnus.com)
3064 * symfile.h (free_named_symtabs): Rename from free_named_symtab.
3065 * symfile.c (clear_symtab_users_once, cashier_psymtab,
3066 free_named_symtabs): Move these routines from symmisc.c.
3067 * symmisc.c (same): same.
3068 (free_symtab): Make non-static.
3069 * symtab.h (free_symtab): Declare as exported void fn now.
3070 * dbxread.c (end_symtab, end_psymtab): Change comments.
3071 (initialize_dbxread): Call dbx_new_init() in case the first
3072 command is add-symbols.
3073 * target.c (dummy_target): Permit add_syms_addr_command.
3075 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3077 Permit symbols to be superseded when new symbol files have
3078 been read in, particularly for VxWorks.
3080 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
3081 to the main file, as well as to include files. Also, put global
3082 functions into the global psymtab, to make "i fun" work.
3083 (end_psymtab): Free named symtabs and psymtabs for a file, once a
3084 new psymtab for it has been read.
3085 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
3086 a file, once a new symtab has been read for it.
3087 * mipsread.c: FIXME. We need to do the same for MIPS, but it
3088 looks harder to determine the top-level block before it's been
3089 queued to the psymtab list.
3091 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
3092 If we have wiped out any old symbol tables, clean up at end of
3094 (symbol_file_command): Don't reference symfile_fns if it's zero.
3096 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
3097 defines for the blocks of a blockvector that contain global and
3098 file-static symbols and the first of the smaller scope contours.
3099 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
3100 decode_line_1, make_symbol_completion_list): Use the above.
3101 * coffread.c (end_symtab, patch_opaque_types): Ditto.
3102 * dbxread.c (end_symtab): Ditto.
3103 * expread.y (block): Ditto.
3104 * mipsread.c (throughout): Ditto.
3105 * symmisc.c (free_named_symtabs): Ditto.
3107 * symtab.c (list_symbols): Process the first symbol of the
3108 static psymbols list.
3109 (types_info): Restore this function from its untimely #if 0.
3110 It's not perfect, but it is better than nothing.
3111 (_initialize_symtab): Restore "info types".
3113 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3115 * m68k-stub.c: Remote stub for 680x0's, created from
3116 rem-m68k.shar (which is removed).
3117 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
3118 Remove RCS log stuff now that we use CVS and it blows our diffs.
3120 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
3122 * symmisc.c (free_named_symtab): Make it work, in its current
3123 kludgy fashion. Change result to indicate if we blew away bkpts.
3124 * dbxread.c (end_symtab): Accumulate result from
3125 free_named_symtab and print warning if we blew user's state.
3126 * symfile.h: free_named_symtab now returns an int.
3128 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
3130 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
3131 is the first symbol read, even if not mainline.
3132 (dbx_psymtab_to_symtab): symfile might be zero, cope.
3133 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
3134 (set_section_command): New command ("section xxx yyy" -- should
3135 be renamed to "set section xxx yyy" FIXME) which sets the
3136 base address of a section of the exec file, overriding the
3137 virtual address that BFD reports.
3139 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
3141 * exec.c: Add add_syms_addr_command to exec_ops, so you can
3142 load symbols at any address while examining an exec file.
3144 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3146 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
3147 for printing the float info is host-dependent, not
3148 target-dependent. FIXME.
3149 * i386-pinsn.c: Move #includes to top, remove useless ones.
3150 * i386-tdep.c: Don't bother including <.../reg.h> since we
3151 don't use it (and it doesn't exist on host systems).
3153 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
3154 Convert negative numbers properly.
3155 (ieee_test): Make numbers really random; fix format arg.
3157 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
3158 * core.c (core_detach): Unpush core_ops, which might not be on
3159 top. We used to just pop the top, which broke things. Don't
3160 need dont_repeat() any more.
3161 (core_file_command): Psst! Don't repeat it.
3162 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
3163 * expprint.c (print_subexp): Avoid switch fallthru on
3164 BINOP_ASSIGN_MODIFY, so we can print += and such.
3165 * frame.h: Fix typo.
3166 * inflow.c (kill_command): After killing inferior, print our
3167 current frame in the core file, if we have one.
3168 (generic_mourn_inferior): When inferior dies, either select
3169 the current frame (in the new target, e.g. core file), or
3170 set both the current and selected frames to NULL.
3172 Changes from Peter Schauer.
3174 * infptrace.c: Avoid <sys/ptrace.h> on USG.
3176 * Make all file names fit in 14 characters (sigh and damn!):
3177 mv hp300hpux-xdep.c hp300ux-xdep.c
3178 mv symmetry-xdep.c symm-xdep.c
3179 mv symmetry-tdep.c symm-tdep.c
3180 mv convex-opcode.h convx-opcode.h
3181 mv tm-vxworks960.h tm-vx960.h
3182 mv tm-vxworks68.h tm-vx68.h
3183 mv Makefile.srcdir Makefile.sdir
3184 mv gdb-int.texinfo gdbint.texinfo
3185 mv remote-sa.m68k.shar rem-m68k.shar
3186 mv remote-multi.shar rem-multi.shar
3187 * Makefile.dist, README, config.gdb, convex-pinsn.c,
3188 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
3189 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
3192 * command.c (user_info_1, user_info): New command for listing
3193 the user-defined commands.
3195 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
3197 * dbxread.c (really_free_pendings): Clear file_symbols
3198 and global_symbols after freeing them; otherwise, running
3199 this function twice (if it appears twice on the cleanup
3200 chain), we try to free things twice.
3202 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
3203 based on text_addr (the address of text in core), not on addr (the
3204 offset between text in the .o file and in core). This change
3205 is from Peter Schauer.
3207 * main.c: Define ALL_CLEANUPS as a cast of zero.
3208 (return_to_top_level): Use it.
3209 (main): Do all cleanups after each command run as part
3210 of the gdb startup sequence. Also do all cleanups before
3211 entering the command loop, and every time we exit the command
3212 loop and reenter. Before, the cleanups from the startup sequence
3213 were being left undone until the first error!
3214 (command_loop): Rename do_nothing cleanup to command_loop_marker
3215 so we can see it easily when examining the cleanup chain.
3216 (init_signals): Add another do_nothing for signal handling.
3217 (quit_command): Only try to kill target if it has execution.
3218 Problems in the target stack got us into a state where
3219 inferior_pid was nonzero but none of the targets had execution.
3220 In this state you couldn't exit gdb.
3222 * dbxread.c: Two changes from Peter Schauer.
3223 (echo_command): Fflush output after an echo command.
3224 (show_history): Pass all args to cmd_show_list.
3226 * utils.c (init_malloc): Call mtrace to turn on tracing
3227 if the environment variable MALLOC_TRACE is set to a file name.
3228 * mtrace.c: Add source file which provides a log of every malloc,
3229 free, and realloc to a trace file.
3230 * mtrace.awk: Add source file which analyzes the trace file.
3231 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
3232 (VERSION): Roll to 3.94.3.
3234 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
3235 (check_duplicates): Don't bother with watchpoints.
3236 (set_raw_breakpoint): Comment about danger of this routine.
3237 (watch_command): Parse and eval all args before calling
3240 * solib.c (find_solib): Avoid error in referencing memory to
3241 see if any more shared libraries have been added. This is
3242 particularly useful if the target has terminated. Bug reported
3245 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
3246 in bringing up 3.94.2 on the Sun-3.
3248 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
3249 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
3250 expression (in scope) before reenabling watchpoint.
3251 * signame.c (init_sigs): Add missing declaration of i, fix
3252 sys_siglist declaration.
3253 * source.c (list_command): Fixed range computation to use
3255 * stack.c (backtrace_command): Do not allow command if target has
3256 no stack, print informative error message.
3257 * target.c (target_command): Do not write into command line
3258 because this fails if the target command is used in a user defined
3259 command. [This change was enhanced by gnu to support any-
3260 unique-prefix matching on target names.]
3261 * valops.c (value_struct_elt): Avoid infinite loop on an
3262 erroneous attempt to print the member of function (try p main.p).
3264 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3266 * expread.y (name_no_typename): Avoid reduce/reduce errors
3267 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
3268 Since the GDB parser really doesn't use name_no_typename in a
3269 name-only context, the parser can't tell the diff between
3270 names and numbers here. Avoid allowing a name_no_typename
3271 to be a NAME_OR_*INT to resolve the conflict.
3273 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3275 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
3277 * valprint.c (val_print_fields): bitfield printing didn't handle
3278 byte order. Indirect through a few more fns to cope.
3280 * values.c (modify_field): also cope with byte order.
3282 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
3284 Cleanup for release 3.94.2:
3286 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
3287 include files. Roll version to 3.94.2.
3289 * coffread.c (init_stringtab): Read length into unsigned char
3290 array before swapping; don't assume 32-bit longs.
3292 * target.c (target_info): Don't bother with get_sym_file, just use
3293 the symfile global variable.
3294 * symtab.h, symfile.c (get_sym_file): Delete it.
3296 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
3297 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
3298 (read_type): Replace one more error() with complain().
3300 * mipsread.c (parse_partial_symbols): Replace printf with complain.
3302 * i960-tdep.c: Fix copyright attribution.
3304 * config.gdb: Quote all backquotes in doublequotes. You can
3305 quote me on that. BSD 4.4 shell found this one.
3307 * infptrace.c (throughout): The third argument to ptrace is an
3310 * infrun.c (wait_for_inferior): When program has terminated, we
3311 have to call target_terminal_ours before we pop that target off
3312 the stack (e.g. before a call to target_kill or
3313 target_mourn_inferior). This fixes problem where a program
3314 terminates, then GDB stops for (tty output) and you have to type
3315 "fg" to the shell to resume it. FIXME: This code for what to
3316 do after termination really should be in normal_stop instead.
3318 * gdbcore.h (read_memory_check): Change declaration; it changed
3321 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
3322 4.4 prereleases, this avoids a bug in their sgtty compatability
3324 * remote.c: Use terminal.h rather than hand-rolling the same.
3326 * signame.c, signame.h (psignal): Arg is unsigned, not int.
3327 * utils.c (strsave, strstr): Fix arg types.
3328 * valprint.c (val_print): lint
3330 MIPS symbol table support from Per Bothner:
3332 * symfile.c (symtab_fns): Remove initializer table that needs to
3333 be hacked for each new symbol file format supported.
3334 (add_symtab_fns): New function, chains symbol table
3335 handlers into the global list.
3336 (symfile_init): Search this list.
3337 * symfile.h: Add next pointer, declare add_symtab_fns.
3338 * coffread.c (_initialize_coffread): Call add_symtab_fns.
3339 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
3341 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
3342 symbol *). Thus, we no longer need the hack to trash
3343 pst->filename. Good, since that hack confused code in symfile.c!
3345 (reorder_symtabs, destroy_all_symtabs): Removed static
3346 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
3347 Instead, the latter now uses a temporary array (stack-allocated
3348 from an obstack, and then freed).
3350 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
3351 haven't been set in the outermost stBlock of a procedure. This was
3352 a problem with f77 binaries on Ultrix 4.?.
3354 (new_symtab, new_symbol, new_type): Continue changing code to use
3355 obstacks more and otherwise conform to dbxread internal style.
3356 Made the free_code of symtabs be free_linetable (as in dbxread)
3357 instead of free_contents. This implies memory leaks when reading
3358 a new symbol table, until the conversion is finished. Did change
3359 (struct symbol) and (struct type) to be allocated on the
3360 symbol_obstack. Blocks and blockvectors are among the things
3363 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3364 tested much, but it solved one problem (reported by Meissner), and
3365 cleans up some other things. The problem happened when an
3366 included file contains actual code (functions) and not just
3367 definitions. The mips coff is a little inconvenient there, since
3368 it may cause a procedure to be mapped to the wrong psymtab.
3370 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3371 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3372 this will need work for the new core paradigm.
3374 Opcode patches from the net:
3376 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3377 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3378 missing altogether - they are added here. From Bruce Bauman.
3379 * mips-opcode.h: The low mask for C0 instructions was too small.
3380 From Garrett Lau. I modified the fix to check the entire 32-bit
3383 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3386 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3388 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3390 * dbxread.c (read_type): Pointer subtraction (value_sub in
3391 valarith.c) sometimes failed because the types of the
3392 pointers being subtracted were not identical.
3393 These differed because dbxread.c was allocating pointer types
3394 using dbx_alloc_type+smash_to_pointer_type instead of
3395 lookup_pointer_type. I failed to find a justification for the
3396 former, so I changed it to use the latter. Similarly, I
3397 replaced smash_to_function_type by lookup_function_type,
3398 and smash_to_reference_type by lookup_reference_type.
3400 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3401 _initialize_mipsread): corresponding changes.
3403 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3405 * source.c (mod_path): Do tilde_expand on each component of the path,
3406 rather than on the (list of) paths as a whole.
3407 (print_source_lines): Set first_line_listed in addition to
3408 current_source_symtab and current_source_line. If the source was
3409 not findable, after a "dir" command to fix the problem,
3410 a "list" would get the wrong lines.
3412 While I was there... (gnu):
3414 * dbxread.c (read_type): Change error to complaint.
3416 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3418 First attempt at detailed understanding of symbol table memory alloc.
3420 * dbxread.c (dbx_symfile_read): Free our string table if we
3421 aren't the mainline. Free the "info" struct since we're done with
3423 (init_psymbol_list): Free any previously allocated psymbol lists.
3424 (): FIXME: Should realloc-down the psymbol lists when done reading
3425 the main symbol file?
3427 * symmisc.c (free_symtab): Free fullname field too.
3429 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3430 (REGISTER_ADDR): Make result type unsigned int.
3432 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3433 define REGEX must also define REGEX1 (its dependency).
3435 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3437 * tconfig/i960: No longer works, points you at vxworks960 or
3440 * xgdb.c, XGDB-README: Remove file. Users can get the much
3442 * Makefile.dist: Remove all trace of xgdb.
3444 * breakpoint.c (breakpoint_1): Pass demangle arg to
3445 print_address_symbolic.
3446 (clear_breakpoints): Remove unused function.
3447 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3448 (breakpoint_re_set): Use catch_errors to do them all anyway.
3450 * gdb-int.texinfo (Host versus Target): Add section on what is
3451 a "host" feature versus what is a "target" feature.
3453 * infcmd.c (path_command, path_info): Handle the PATH variable
3454 (object search path) as conveniently as the source search path.
3455 * environ.c (set_in_environ): Set some vars in GDB's environment,
3456 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3457 * source.c (mod_path): New function, from guts of
3458 directory_command, modifies a path. Used by path_command.
3459 (directory_command): Call it.
3460 * defs.h (strsave): Declare.
3462 * utils.c (sevenbit_strings): Add new printing option.
3463 (printchar): Use it.
3464 (strsave): Provide this handy helper routine.
3465 (set_width_command): Rename set_screen_width_command.
3466 (_initialize_utils): "set screen-width" => "set width";
3467 "set screen-height" => "set height"; add sevenbit-strings.
3469 * infcmd.c (do_registers_info): Print floating point registers
3470 in raw hex as well as float format, regardless of whether it is
3471 a "virtual" convertible register.
3472 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3473 regs as a double, just in case it's being used that way.
3474 * values.c (unpack_long): Comment on array/function coercion.
3475 (unpack_double): Argument is in target byte order now. For
3476 integer arguments, just call unpack_long and float the result.
3477 * m68k-tdep.c: include defs.h for "const" handling.
3478 * remote-nindy.c: Use ieee-float stuff.
3479 (nindy_fetch_registers): Unpack double regs to host double, then
3481 (nindy_store_registers): Pack extendeds to host double, flip
3482 around by misusing unpack_double, send as target double.
3484 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3485 zero, as when stopped at the first instruction of a process.
3487 * blockframe.c: Fix filename in comment (param.h => tm.h).
3488 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3489 * tm-68k.h: Fix typos.
3491 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3493 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3495 * coredep.c (fetch_core_registers): Pass end-address of register
3496 section to register_addr as expected. Don't call supply_register
3497 if we'd just pass it garbage.
3499 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3501 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3503 * target.c (push_target, target_info): Cast enums to int for < or
3506 * stack.c (print_frame_info): Identify source file & line
3507 even if we can't print it.
3509 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3511 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3513 Clean up IEEE floating point support.
3515 * ieee-float.h: New file.
3516 * ieee-float.c: Write real routines to convert between host
3517 doubles and various target IEEE extendeds.
3518 * m68k-xdep.c: Eliminate assembler code for extended floats.
3519 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
3520 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3521 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3522 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3523 double_to_ieee_extended.
3524 * i960-tdep.c: Define ext_format_i960.
3525 * m68k-tdep.c: Define ext_format_68881.
3526 * sparc-tdep.c: Define ext_format_sparc, though unused.
3527 * Makefile.dist (HFILES): Add ieee-float.h.
3528 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT

3534 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3535 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3536 * tconfig/nindy960: Remove reference to coffstrip.o.
3538 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3540 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3542 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3543 * dbxread.c: Remove static symfile_bfd.
3544 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3546 * inftarg.c (child_detach): Pop the child_ops vector if the
3547 detach is successful.
3548 * remote-nindy.c (nindy_create_inferior): Don't push a new
3549 nindy_ops since nindy uses the same one for execution and memory
3551 * core.c (core_ops): Use child_attach and child_create_inferior
3552 rather than default attach and create_inferior functions.
3554 Handle floating point registers in core files.
3556 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3557 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3558 This version untested since BFD doesn't yet support sun3 core
3560 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3561 conventions. Fix comments and style. This version has not
3562 been compiled yet, since we have no HP inhouse.
3563 * core.c (get_core_registers): Look for two sections, ".reg"
3564 and ".reg2", and pass both to fetch_core_registers sequentially.
3566 Revise directory path yet again.
3568 * source.c (forget_cached_source_info): Not static any more.
3569 (init_source_path): New default source path is "$cdir:$cwd".
3570 (dir_command): Handle variable arguments ($cdir, $cwd).
3571 (source_info): Print "Compilation directory" rather than
3572 "Originally compiled in" to remind people of $cdir.
3573 (openp): If the path contains $cwd, use current directory.
3574 (open_source_file): If compilation directory is known, replace
3575 first $cdir in path with the compilation directory.
3576 (print_source_lines): Even if we can't print the lines, set the
3577 current symtab and line for future commands like "info source" or
3578 "breakpoint". Also, error message now contains the file name,
3579 line number, and file access error message.
3580 (_initialize_source): Fix help text to describe changes.
3581 * main.c (cd_command): Forget cached source info when we chdir.
3582 * utils.c (strstr): Add simple implementation.

3586 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3587 Byte-swap COFF symbol tables if necessary when reading them in.
3588 Use complain() to replace error message in one spot. Needs
3589 corresponding change in bfd/coff-code.h to make some symbol
3590 swapping routines non-static.
3592 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3594 Merge changes from Eirik Fuller, for UTek.

3602 declarations of errno.
3604 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3606 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3607 <rpc/rpc.h> and <rpc/types.h>.
3609 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3611 * i960-tdep.c (examine_prologue): Add new argument limit,
3612 which stops the scan at the end of the prologue, or at the PC.
3613 This fixes a problem where it walks down into the code for the
3614 user's statements if that code looks like function prologues.
3615 Mark Fox and I have been bouncing this code back and forth, making
3616 small changes to it. Callers changed to match.
3618 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3620 Cleanup for gdb-3.94 release final:
3622 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3623 the .c files from vx-share and nindy-share, from the various
3624 macros, since they are not found via ALLDEPFILES.
3625 (SFILES): Add tm-i960.h.
3626 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3627 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3629 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3630 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.

3634 * am29k-tdep.c: Add contribution line.
3635 (examine_prologue): Cache information about function prologues in
3636 the misc-function-vector to avoid lots of references over the
3637 serial line while examining instructions.
3639 * core.c (core_close): New function made from cleanup_core.
3641 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3642 remote-vx.c, remote.c, target.c, target.h,
3643 Update target_ops vector to add attach, close, and load entries.
3644 Use add_syms_addr_command, not add_file_addr_command, for
3645 add_file. Break out close routine from existing code.
3647 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3648 they are in an obstack.
3649 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3651 (define_symbol): Add symbol type parameter; change callers;
3652 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3653 it to influence the symbol class on the i960.
3654 (define_symbol): Swap LOC_CONST's into target byte order.
3656 * exec.c (exec_close): New function.
3657 (exec_file_command): Call it.
3659 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3660 Fix byte order of frame pointer.
3661 (read_var_value): Result of 0 if var's value can't be found,
3662 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3663 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3664 (locate_var_value): Use read_var_value and use its lazy address
3665 as the location of the var's value. Lint.
3667 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3670 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3671 obsolete Intel versions in favor of vxgdb versions.
3672 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3673 code dealing with byte order of values, which Intel did in host byte
3674 order rather than gdb-4's target byte order.
3675 (i960_frame_chain_valid): Move to nindy-tdep.c.
3676 (examine_prologue, skip_prologue, frame_find_saved_regs,
3677 frame_args_address, leafproc_return, saved_pc_after_call,
3678 pop_frame): Add vxgdb versions from Mark Fox.
3679 (examine_prologue, frame_struct_result_address): Add code
3680 to deal with the saved value of G13 (struct return address
3682 (frame_args_address): Modify Mark's version to prefer the
3683 saved value over the current value in the topmost frame.
3684 Cache result in the frame info to avoid performance hair in
3686 (print_fault): Add gdb960 code for printing faults.
3687 (_initialize_i960): Actually call check_host.
3689 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3690 add stub routines. FIXME, these currently just return zero!
3692 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3693 (attach_command): Call target_attach, not target_open, now.
3695 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3696 (child_attach): Rename from child_open.
3697 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3698 don't confuse it with a zero step_resume_break_address.
3700 * inftarg.c (child_detach): Eliminate inferior_pid test.
3701 (child_files_info): Clean up message a bit.
3702 (child_ops): Use child_attach, not child_open, to attach.
3704 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3705 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3706 findvar.c to here, since it depends on the contents of the
3707 shadow_contents of breakpoints, but keep if #if 0 since it is
3710 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3713 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3714 (ptype_command, display_command): Eliminate have_inferior_p and
3715 have_core_file_p in favor of target_has_stack or
3716 target_has_execution.
3717 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3718 code for actually finding the values of arguments, though we still
3719 keep track of the maximum stack offset for use in printing unnamed
3720 arguments. Handle missing FRAME_ARGS_ADDRESS.
3722 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3723 (struct nindy_regs): Define registers passed to/from nindy.
3724 (nindy_fetch_registers, nindy_store-registers): Translate between
3725 nindy and GDB formats for the registers.
3726 (dcache_init): Statically allocate the cache, since it was being
3727 allocated by a malloc that was never freed anyway.
3728 (nindy_create_inferior): Error, not core dump, if no exec file.
3729 (nindy_before_main_loop): Use target_load, not target_add_file.
3731 * remote-vx.c (net_load): Specify large timeout for load
3732 requests. Allow user to break out with INTERRUPT.
3733 (net_break): Remove useless code, clean up. Change callers.
3734 (parse-args, skip_white_space, find_white_space): Clean up arg
3735 parsing to cope with quoted strings.
3736 (net_wait, net_quit): Never call error, just return status.
3737 (vx_read_register, vx_write_register): Cleanup status checking.
3738 #ifdef the code based on which CPU we are using (960 or 68k),
3739 FIXME, this should be completely general but it isn't yet.
3740 (vx_xfer_memory, vx_resume): Cleanup status checking.
3741 (vx_run_files_info): Improve message.
3742 (vx_load_command): Renamed from vx_add_file_command. Allow load
3744 (net_ptrace): Remove unused routine.
3745 (vx_wait): Adopt code from vxgdb960 to cope with broken
3746 connections to target machine and prompt to disconnect. Remove
3747 debug printouts. Map some EVENT_'s to SIGnals.
3748 (add_symbol_stub, vx_open): Print names of object files we found,
3749 and "ok" if we read their symbols OK. Clarify output in general.
3750 (vx_attach, vx_detach, vx_kill): Add these commands.
3751 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3752 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3753 "info files" output, and create_inferior, since we already have
3756 * stack.c (frame_info): Replace Frame_unknown with 0.
3757 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3758 (return_command): Pop until the PC matches as well as the FP,
3759 so it works even if the FP is shared with another function,
3760 as in "frameless" or "leaf" procedures.
3762 * symfile.c (load_command): renamed from add_file_target_command.
3763 (add_syms_addr_command): renamed from add_file_addr_command.
3764 (add_syms_command): Stub to call target_add_syms.
3765 (_initialize_symfile): Change command names and descriptions,
3766 add-file => add-syms, and load from alias to its own command.
3768 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3769 maybe_kill_then_create_inferior): Default for attempts to start
3770 a process, if one is already running, is to ask about killing
3771 it and retry if yes.
3772 (upstack_create_inferior): #if-0 it, strata obsolete it.
3773 (push_target, unpush_target, pop_target): to_close() a target
3774 before unstacking it.
3775 (target_info): Renamed from target_files_info.
3776 (_initialize_targets): Rename "i files" as "i target", accessible
3779 * target.h: Improve comments about the target_ vectored routines.
3781 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3782 Convert commenting style to standard GNU style.

3784 (SKIP_PROLOGUE): No longer a no-op.
3785 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3786 (*_REGNUM): Sort register numbers.
3787 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3788 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3789 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3790 are now 10 byte extendeds, not 8 byte doubles.
3791 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3792 for nindy versus vxworks targets. FIXME, this should possibly go
3793 in the target vector.
3794 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3795 frame_saved_regs and arg pointer with each frame.
3796 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3797 (FRAME_ARGS_ADDRESS): Use cached result.
3798 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3799 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3800 (PRINT_RAMDON_SIGNAL): Call print_fault.
3801 (POP_FRAME): Now works.
3803 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3804 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3805 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3806 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3809 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3810 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3812 * valarith.c (value_subscripted_rvalue): Avoid handling
3813 floats and doubles specially; it gave alignment errors. Lint.
3815 * valops.c (value_of_variable, value_of_this): Error if unknown
3818 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3819 to avoid alignment problems.
3820 (value_print): Handle unknown value address.
3821 (cplus_val_print): Two args are ignored; remove them. Change caller.
3822 (val_print): Use unpack_long rather than pointer-deref.
3825 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3826 to avoid alignment problems.
3827 (value_being_returned): Error if return value unknown.
3828 (set_return_value): Add bogosity warning, FIXME. *
3830 * TODO: A woman's work is never done.
3832 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3833 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3834 Add ieee-float.o to OBS.
3835 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3836 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3837 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3839 Changes to generalize the VxWorks RPC protocol slightly, to handle
3840 i960 as well as 68000.
3842 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3843 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3844 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3845 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3846 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3847 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3848 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3849 so they will move in target byte order rather than network
3850 byte order (happens to be the same).
3852 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3854 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3856 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3859 Add contribution lines to various files, showing where they
3862 * breakpoint.c (break_insn, check_break_insn_size,
3863 read_memory_nobpt): Remove to mem-break.c.
3865 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3868 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3869 entry has bad register number. This change is not
3870 tested in this release, FIXME.
3872 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3875 * value.h: Force value's contents field to be aligned to hold
3876 at least a double or a long long (if supported). This avoids
3877 doing bcopy's in and out of the contents field.
3879 (step_1): Avoid coredump under obscure circumstances when we
3882 * symtab.h (misc_info): Add field to misc function vector for
3883 any kind of cached information the target code desires. AMD
3884 29000 uses this to avoid repeating examine_function_prologue's.
3886 * coffread.c: Lint. Remove static symfile, read_section_header.
3887 core.c (have_core_file_p): Lint: remove.
3888 expprint.c (print_subexp): Lint.
3889 infptrace.c, valops.c, valprint.c: lint.
3891 Roll in changes from vxgdb-5.0.1:
3893 * symtab.h: Comment byte order of each address class. Add
3894 LOC_LOCAL_ARG for frame-relative args (960).
3895 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3896 symtab.c, symmisc.c: ditto.
3898 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3900 * remote.c (remote_resume): Error if resume with a signal.
3902 * symfile.c (prim_record_misc_function): Clear misc_info.
3903 (fill_in_vptr_fieldno): Check stub type of arg.
3905 * valops.c (value_cast): Avoid looking up names of types whose
3906 name we don't know, to prevent coredump. Sun CC produces typedef
3907 rtx and the name of *rtx is zero...
3909 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3911 Roll in changes from final AMD 29000 port (Tiemann).
3913 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3914 for ../include/a.out.encap.h. This might not work now that BFD
3915 is separately compiled. Instead, BFD support for encap will have
3916 to translate machine type 29k into the right COFF_MAGIC.
3918 * infcmd.c: Remove references to inferior_pid that aren't used
3919 in actual ptrace calls; use target_has_execution, etc.
3920 (have_inferior_p): Remove function.
3921 (program_info): Print target info rather than "process number";
3922 avoid gratuitous messages unless from_tty.
3923 (run_stack_dummy, finish_command): Set proceed_to_finish.
3924 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3925 main.c: Lint. Lose have_inferior_p().
3926 inferior.h (have_inferior_p): Remove, lint.
3927 (proceed_to_finish): Add flag to ask that all regs be saved
3928 by normal_stop, for the few commands that need it, speeding up
3929 serial I/O. Add comments to stop_registers.
3931 * remote-eb.c: Remove newline from breakpoint message we grep
3932 for. Never time out when running the user program.
3936 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3938 Roll in changes from vxgdb-5.0.1:
3940 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3941 symbol in its raw form, we are processing an unlinked ".o" file.
3942 See if the target environment has assigned it an address, using
3943 target_lookup_symbol (VxWorks does), and enter it into the symtab
3946 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3947 68k versions for a simpler version that assumes zero FP at bottom.
3948 Fixes bug of truncated stack reports.
3950 * target.h (target_lookup_symbol): Define this routine's args
3951 and result, finally.
3953 * target.c (nosymbol): Default routine for target_lookup_symbol.
3954 (target_default): Default lookup_symbol and call_function too.
3955 (files_info): Only print has_all_memory warning if a non-dummy
3958 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3959 vx_convert_from_virtual): If target does not have floating point,
3960 zero register "values", and avoid doing cross-net conversions.
3961 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3962 (vx_open): Rearrange code that attaches to target and reads
3963 symbols for all loaded modules, to work if some of the modules
3964 are not accessible. Add symbol_stub() and add_symbol_stub()
3965 as callbacks from catch_errors(). Allow connect attempt to be
3966 interrupted painlessly with ^C (FIXME, there are still some bugs
3967 if the interrupt happens during symbol reading.). Print
3968 final message with puts_filtered, since symbol messages are
3973 * main.c (catch_errors): Only print errstring if non-null.
3974 (command_loop): Avoid an ioctl per command to test ISATTY.
3976 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3977 (vx_xfer_memory): Return correct result!
3978 (vx_files_info): Indicate whether target has float or not.
3979 (vx_lookup_symbol): Complain, not error, if target gone.
3980 (vx_open): Print "Connected" msg before disabling immediate-quit.
3981 [FIXME: lookup_symbol and vx_open changes need testing.]
3983 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3984 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3985 contributor lines and update copyrights to 1991.
3987 Changes from an attempted H-PUX host port:
3989 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3990 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3991 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3992 * remote-vx.c: include <sys/time.h> for HPUX.
3993 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3994 "core_file_command" routine to BFD regime. May not work yet.
3996 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3998 * xgdb.c: Replace X10 version with some VJ version.
3999 (FIXME: Its copyright assignment is not on record.)
4000 * xgdb.c: Update include files to X11R4 (Xaw crud).
4001 (xgdb_display_source, create_text_widget): fix call to
4002 get_filename_and_charpos. Rewack source window stuff for X11R4
4003 (gleaned from include files, and "nm's" of binary libraries, since
4004 I had no doc available).
4005 (append_selection, append_selection_word): Disable with FIXME
4006 since R4 changed interface here.
4007 (create_buttons): Add back the old set of buttons.
4008 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
4010 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
4011 Roll VERSION to 3.94 (not yet final though).
4013 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4015 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
4016 obstack_int_grow, obstack_int_grow_fast): Eliminate
4017 cast on left of assignment, which gives MIPS cc fits and is
4020 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
4021 F_ALIAS. Use printf, not fprintf, when not passing a file
4023 (compare_opcodes): Check that identical instructions have
4024 identical opcodes, complain otherwise.
4026 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
4027 was reported by Roland McGrath.
4028 (unimp): Only match if exactly zero instruction. (Roland)
4029 (branches and traps): Generate all variations of these
4030 instructions with macros, based on a single call that defines
4031 each condition name and its binary representation.
4032 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
4034 * valprint.c (val_print_fields): Take, and use, format parameter.
4035 This means that "p/x struct" again prints the elements in the
4036 desired format. Changed callers.
4038 * stack.c (frame_info): Use filtered output, and indicate wrap
4039 points. Remove kludgy formatting designed to avoid line wrap.
4041 * utils.c (wrap_here): If the line is already full (because
4042 we had printed a long indent or long wrapped string), do an
4043 immediate newline-and-indent.
4045 * m68k-pinsn.c (print_insn_arg): Bugfix from
4046 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
4047 instruction is incorrectly disassembled as bkpt #8.
4049 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
4050 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
4051 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
4052 and then will dump core (sometimes). I traced it back to an
4053 uninitialized symfile_name in psymtab_to_symtab.
4054 (const_vol_complaint): Add quotes to message.
4055 (define_symbol): Only believe line number if gcc_compiled.
4056 Avoid allocating symbol if we will not return it.
4058 Add target strata support so that newly established targets go
4059 into their right place in the target stack (e.g. a new exec file
4060 doesn't wipe out the ability to access the running process).
4062 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
4063 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
4064 and initialize it properly in all the targets.
4066 * target.h: Document strata. Change return type of push_target.
4068 * target.c (nomemory): new function for dummy memory access.
4069 (tcomplain): Rename complain, now also used in symfile.c.
4070 (push_target): Push targets within strata. New return value shows
4071 whether new target is on top of stack or not. Always keep dummy
4073 (target_files_info): Ignore dummy target.
4075 * core.c (core_open): Warn user, and skip accessing file, if the
4076 core target is not the topmost target in the stack.
4077 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
4080 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
4081 target_ops, it doesn't belong there since we have no regs there.
4082 Change name of target from machine => memory to clarify.
4084 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
4086 * Freeze version 3.93 for release.
4088 * Makefile.dist: Handle vx-share and nindy-share subdirs
4089 properly when building gdb.tar.Z.
4091 * symtab.c: lint; add no_symtab_msg to consolidate the messages
4092 printed in various places, so I could change just one copy.
4094 * dbxread.c, coffread.c: Change references to bfd->iostream
4095 to cast to FILE *, now that BFD avoids needing types defined
4096 in other header files.
4098 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
4100 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
4101 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
4102 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
4103 (actually gcc -Wall).
4105 * dbxread.c: Remove first_global_sym, last_global_sym, since
4106 they are never referenced.
4108 * defs.h (baud_rate): Declare.
4109 main.c: Define it, and add the -b option to set it.
4111 * gdb-int.texinfo: Add text on how to define a new host or target
4112 architecture, prompted by Per Bothner's questions about MIPS
4115 * gdb.texinfo: Document "complaints". Change doc of -q since
4116 gdb no longer prints the copyright and blurb if you specify a file
4117 name to be debugged (just like Emacs). Add doc for Nindy-specific
4118 command line flags for specifying target serial port and such.
4119 Update copyright to 1991.
4121 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
4122 has taken over for us the job of ripping up executable files. The
4123 crud caused Per Bothner's port to not compile.
4125 * infrun.c (normal_stop): Avoid printing "Program exited
4126 normally" if we are in batch mode. This allows a GDB which
4127 executes a program on a target system, to behave like a Unix
4128 command (input from stdin, output to stdout, no extraneous
4131 * main.c (main): Allow additional machine-dependent command line
4132 options to be specified with the ADDITIONAL_OPTIONS,
4133 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
4134 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
4135 processing to occur just before the main loop with
4136 BEFORE_MAIN_LOOP_HOOK.
4137 (main): If a "core file" argument is specified, and it is not a
4138 core file, try it as a process ID to attach.
4139 (symbol_completion_function): Attempt to cope with
4140 "show screen-" TAB, not very successfully. This needs more work,
4142 (batch_file): New function, returns whether we are reading
4143 commands from an interactive tty on stdin, or from somewhere else.
4144 Called by normal_stop since it doesn't get from_tty passed down
4145 to it like many commands do.
4147 * remote-nindy.c: Handle command line options for nindy
4149 (nindy_before_main_loop): Prompt user for tty name if they
4150 don't specify it before getting to the interactive command loop.
4152 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
4153 and -r command line options. Also add hook before main loop
4154 to make it easy to specify a tty.
4156 * TODO: More things to do, one done.
4158 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
4160 * dbxread.c: Make complaint() calls pass pointer, not struct.
4161 Add complaints about badly formatted C++ type information
4162 (const/volatile indicator, and parse errors resulting in
4163 error_type). Fix C++ virtual member fn comment.
4164 (read_struct_type): Avoid bumping pointer if we got a parse
4165 error; this prevents our walking beyond the end of a string.
4166 Terminate loop on null char as well as semicolon.
4167 (process_one_symbol): Fix the LBRAC fix so that it uses the
4168 last previous SLINE, FUN, or SO record's PC address. C++ debug
4169 symbols did not have SLINE records in a useful order compared
4170 to the LBRAC records.
4171 (define_symbol): Handle "catch" records.
4173 * symtab.c (check_stub_type): Added new complain
4174 `stub_noname_complain' and added a consistency check to
4175 keep the debugger from crashing when finishing from an
4176 exception frame. A real fix will be needed later.
4178 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
4180 * infcmd.c (attach_command): Make global.
4182 * Makefile.dist (REMOTE_OBS): Make these compile by default,
4183 but make them easy to comment out. Perhaps later they should
4184 be enabled by what CPU you configure for? FIXME.
4185 (VERSION): Roll to 3.93.
4186 (pinsn.o): Remove rule for obsolete file.
4187 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
4189 Run down a problem that manifested by printing the wrong function
4190 name in stack traces of read_ofile_symtab. Turned out that the
4191 problem was the SunOS 4.1.1 (and previous) C compiler outputs
4192 the LBRAC symbol with an address in the *data* segment, which
4193 blew our binary search through the blocks.
4195 * dbxread.c: Use the complain() facility consistently to bitch
4196 about problems in the symbol file we are reading.
4197 (finish_block): Add code to check the nesting of the blocks;
4198 complain and Procrust them to fit if wrong.
4199 (make_blockvector): Check the order of the blocks, complain
4200 [but don't cope] if wrong.
4201 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
4202 symbols to be sure their PC value is greater than the last SLINE
4203 (line number) symbol we've seen, complaining and adopting the
4204 SLINE PC value if wrong.
4206 * symfile.h (struct complaint, complaint_root, complain,
4207 clear_complaints): Add.
4208 * symfile.c (complain, complaint_root, clear_complaints): Add
4209 facility to deal with non-fatal complaints and to regularize their
4211 (symbol_file_add): Clear complaint counters to allow new complaints.
4212 (initialize_symfile): Add 'set complaints' and 'show complaints'.
4214 * dbxread.c (dbx_symfile_read): Remember the address and size
4215 of the string table for the main symbol file, so we won't read it
4217 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
4218 to avoid reading the string table yet again. Lint.
4219 (throughout): Improve filtered output, including word wrap.
4220 (read_range_type): Improve Bothner's fix to handle other types too.
4222 * utils.c: Improve line wrap implementation. Handle unlimited
4223 width by making chars_per_line unsigned.
4224 (puts_filtered): New, easy, function.
4226 * defs.h (puts_filtered): add.
4228 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
4229 call the identical sort_symtab_syms() in symfile.c instead.
4231 * expread.y: Suggest the `file' command rather than `symbol-file'.
4233 * command.h (enum var_types): Add zinteger for seroable
4235 * command.c (do_setshow_command): Handle var_zinteger. Restructure
4236 nested if's into a switch.
4238 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
4239 we did not stop because of a breakpoint (it must have been for
4240 some other reason, like a "stepi"), so don't print anything.
4242 * symtab.c: Include <sys/types.h> all the time. Now that BFD
4243 doesn't include <sys/types.h>, old SunOS's require it for
4246 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
4248 A test port of gdb-3.92.6 to the Sony NEWS.
4251 Don't normally link in remote- or vx stuff.
4252 Some of it doesn't compile, and it wastes space for 99% of the users.
4253 Remove reference to no-longer-used HAVE_VPRINTF.
4254 Fixed BFD_DEP typo to BFD_DIR.
4256 Fix cast in arg to bfd_h_getlong.
4257 Make char *prefix be const.
4258 Fix how certain range types are mapped into builtin unsigned int types.
4260 Remove 2 #includes. They cause errors (on Sony, at least),
4261 and aren't needed (they wern't in earlier versions).
4263 print_address_symbolic should never demangle labels
4264 (since it prints *assembler-level* labels).
4266 [This was superseded by the change to printcmd below.]
4269 Add some "volatile" return types to avoid warnings.
4270 If MISSING_VPRINTF add vprintf function and not just macro
4271 (since vprintf is used in printcmd.c).
4273 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
4274 (The latter isn't grokked by some PCC-based compilers.)
4276 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
4278 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
4279 * nindy-share/coffstrip.c
4280 Added some forward declarations (otherwise, gcc complains
4281 about implicit extern redefined as static).
4283 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
4285 Changes inspired by Per Bothner:
4286 * printcmd.c (print_address_symbolic): Take additional parameter
4287 specifying whether to demangle.
4288 (print_address): Pass in asm_demangle to control demangling.
4289 (print_address_demangle): New fn, takes explicit arg to control
4291 * utils.c: Add new vars demangle and asm_demangle, and let them
4293 (fputs_demangled): If !demangle, just print the argument.
4294 (fprint_symbol): If !demangle, just print raw symbol.
4295 * valprint.c (val_print): Call print_address_demangle rather than
4296 print_address, to cause demangling to depend on the global
4297 rather than assembler-level demangling setting.
4298 * WHATS.NEW, gdb.texinfo: Document.
4300 * main.c (show_command): Show all settings if no arg.
4301 (initialize_main): Make "info set" the same as naked "show".
4302 * command.c (cmd_show_list): Handle prefix commands in the
4303 list, and print the name of the setting as well as its English
4304 description and value.
4306 Allow gdb functions to specify where a line should wrap if it
4307 exceeds the size of a terminal line. Use it to make the output
4309 * utils.c (set_screen_width_command): New fn, mallocs a buffer
4310 of the right size when screen width changes.
4311 (set_screensize_command, screensize_info): Remove #if 0'd fns.
4312 (wrap_here): New fn, indicates a point in the output where we
4313 should wrap the line rather than just letting it overflow at a
4315 (fputs_filtered): Implement wrapping.
4316 (n_spaces): New fn, returns a pointer to N spaces.
4317 (print_spaces_filtered): Use n_spaces.
4318 * defs.h (n_spaces): Declare.
4319 * stack.c (print_frame_info): Wrap with 4-space indent after
4320 fn name and before filename and line number.
4321 * printcmd.c (print_frame_args): Wrap with 4-space indent
4322 before each argument name is printed.
4323 * valprint.c (value_print): Wrap with no indentation before
4325 (val_print_fields): Wrap with indentation relative to nesting
4326 level before each field name.
4327 (val_print): Wrap with nesting indentation before array elements.
4328 * command.c (do_setshow_command): Avoid extra newlines,
4329 wrap with 4-space indent around values printed, end with period.
4330 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
4332 * breakpoint.c (breakpoint_1): Implement addressprint for
4333 "info breakpoints" display. Change file name and line number
4334 format to " at file:nnn" rather than " (file line nnn)".
4335 * gdb.texinfo: Document.
4338 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4340 Frozen for gdb-3.92.6 release.
4342 README, WHATS.NEW: Update for 3.92.6 release.
4344 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
4345 coffread.o from configs since it is now built by default.
4346 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
4347 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
4348 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
4349 from configs since it is now built by default.
4351 Makefile.dist: Update for release 3.92.6. Handle files that
4352 have been moved to ../include, ../getopt, or ../bfd. Add
4353 saber.suppress and tests directory. Add config.status to
4354 the release (it will say "none").
4356 coredep.c: Minor formatting fixes.
4358 These changes were made in early December but only checked in now:
4359 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4360 nindy-share/nindy.c: lint
4361 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4362 register values coming back from the target; we store values
4363 in target byte order everywhere.
4365 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4367 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4369 * valprint.c (cplus_val_print, val_print_fields): New functions,
4370 which print C++ objects. They conspire to avoid printing a
4371 virtual base class more than once, following all the twists and
4372 turns of C++ virtual base rules.
4373 (val_print): Call the above rather than do it by hand.
4375 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4376 symbol file, not for added files like shared libs. This really
4377 needs to be generalized to a timestamp per file.
4379 * core.c (cleanup_core): Avoid coredump if no core file.
4381 * config.gdb: Accept -host or -target in place of +host or
4384 * coffread.c (find_linenos): Avoid desupported BFD interface
4385 to line numbers. We still read them manually rather than using
4386 BFD's "generic" features.
4388 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4390 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4392 * Makefile.dist: Eliminate use of $< in explicit targets.
4394 * readline/Makefile: Use $< rather than $*.c, which does not
4395 include the VPATH in GNU Make.
4397 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4398 copies of tconfig/i960, added for global configuration
4399 compatability. All i960 versions can read both coff and b.out.
4401 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4402 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4405 * TODO: Think of more things to do.
4407 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4409 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4410 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4411 64-bit float conversion.
4413 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4414 equivalent to sun?os4 so global config works.
4416 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4418 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4420 * main.c: Only declare linesize once; declare pagesize not at
4421 all, since it is never used.
4422 (main): Clear newly allocated line before it is used.
4424 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4426 Further stabilization for the Intel 960.
4428 * Makefile.dist: Parameterize the location of the "include"
4429 and "bfd" directories, as well as "getopt". Add symfile.c.
4430 Link in both dbxread and coffread. Fix up "make depend" to
4431 rewack the locations of include, bfd, and getopt in its output.
4433 * README: Document moving include files, improve some of
4436 * coffread.c: Move common code out to symfile.c. Change
4437 symbol_file_command style interface to use new *_symfile_init
4438 and *_symfile_read interface under BFD. Use BFD internal
4439 info to locate line table, symbols, etc.
4441 * core.c (core_fetch_registers): Rename to get_core_registers
4442 to avoid confusion with fetch_core_registers.
4443 (register_addr): Move to coredep.c, which is already machine
4444 dependent. This leaves core.c pretty clean of dependencies.
4446 * coredep.c (register_addr): Accept this routine from core.c.
4448 * dbxread.c: Move common code (with coffread.c, etc) into new
4449 symfile.c. Each psymtab now contains a pointer to the
4450 format-dependent function that knows how to read it in. Make
4452 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4453 (process_one_symbol): Add code to complain about a "compiler bug
4454 we muzzle here", if we actually see it.
4456 * eval.c (evaluate_subexp): Insert missing "break" statements
4457 in code that determines whether a variable is an lvalue in
4458 memory, register, or whatever. I detected this via a compiler
4459 bug in which it *almost* mashed out the whole switch statement.
4461 * gdb-int.texinfo: Add minor sections on configuring gdb for
4462 release, and about the README file.
4464 * infcmd.c (registers_info): Fix formatting somewhat. Still
4465 not as pretty as before, but it handles byte swapping.
4467 * remote-nindy.c: If data cache routines are interrupted while
4468 waiting for the remote end, be sure that any uninitialized cache
4469 blocks are on the free list, not on the valid list!
4471 * symfile.h: Flesh out this header file with all the various
4472 routines and variables that have been merged in from dbxread.c
4473 coffread.c, and symtab.c to symfile.c.
4475 * symfile.c: New file, containing code common to dbxread.c,
4476 coffread.c, and some code from symtab.c. All generic code for
4477 reading symbol files should be in here now.
4478 (unrecord_misc_function): Remove unused function.
4480 * symtab.h: Remove file-reading things to symfile.h.
4482 * symtab.c: Remove file-reading things to symfile.c.
4484 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4485 to decode i960 fault types.
4487 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4488 target.c: Change type of the "resume" function from int to void,
4489 since its result was never used.
4491 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4493 * main.c: Replace "stupid" with "caution"; you now "set caution
4496 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4498 * infcmd.c (do_registers_info): Call val_print to deal with the
4499 byte order of the registers being printed. FIXME, this makes
4500 the formatting of the output uglier.
4502 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4503 defined, call it for signals the debugger doesn't itself use.
4504 The i960 uses this for more detailed fault information.
4506 * remote.c (remote_open): If arg is null, print help rather than
4509 * sparc-xdep.c (register_valid): Avoid declaring size, since
4510 various modules will think of various sizes depending on the
4511 architecture of their tm-file. FIXME, we need protection against
4512 actually entering one of those modules, which would clobber
4513 storage if not for the target architecture compiled into gdb.
4515 * stack.c (up_command, down_command): Always print the frame
4517 (up_silently_command, down_silently_command): New commands
4520 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4522 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4523 more parameters than it used to.
4525 * findvar.c (registers): Increase slop to 256 bytes, which should
4526 protect us against even most RISC machines with large register
4528 (locate_var_value): Move declaration inside related ifdef.
4530 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4531 throughout, to avoid throwing away buffered input from the board.
4532 (nindy_wait): Supply_register takes addr_of_value, not value.
4533 (i960_print_fault): Renamed from i80960_fault.
4534 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4535 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4537 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4538 we can set the PC in the call to proceed(). Unpush nindy_ops
4539 before pushing it on top, to avoid message to user. Eliminate
4540 commentary from Unix machines that just misleads here.
4541 (reset_command): Fix error message to suggest target command.
4543 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4545 Release 3.92.5 as frozen.
4547 Stabilize the merged release...with help from lint, Saber C,
4550 Everywhere: Add include files needed to declare return types
4551 of functions called.
4553 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4555 * breakpoint.h: Add undeclared breakpoint functions, and some
4556 functions for display handling since I couldn't think of a better
4559 * breakpoint.c (insert_breakpoints): Make code for disabling
4560 shared library bkpts more likely to work. It's used when we
4561 rerun a program and stop before the shared library has been
4563 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4564 cast from pointer, so it squeezes through catch_errors.
4565 (bpstat_stop_status): Fix logic broken some time ago. We now
4566 always create a bpstat if the stop address matches a breakpoint,
4567 even if we don't stop there -- just like the old code used to do
4568 before I got my fingers into it (sigh).
4569 (breakpoint_1): Print "ignore count" after "stop only if"
4570 condition, since that's how it actually works.
4571 (mention): Handle watchpoints as well as breakpoints.
4572 (watch_command): use set_raw_breakpoint and mention to do most
4573 of the work (and initialize all the fields!). Only pass one
4574 arg to parse_c_expression, since that's all it takes.
4576 * command.c (not_just_help_class_command): Rename arg to args
4577 since we ignore "unused argument" warnings on vars named "args".
4578 inflow.c (child_terminal_info): ditto.
4579 infptrace.c (kill_inferior): ditto
4580 main.c (catch_errors, version_info, quit_command, pwd_command,
4581 source_command, dump_me_command, editing_info,
4582 set_history_size_command, set_history, show_history,
4584 stack.c (locals_info): ditto
4585 target.c (target_files_info): ditto
4586 valprint.c (set_input_radix, set_output_radix): ditto
4588 * core.c: Remove old variables for handling core and exec file
4589 sections (data_start, data_end, stack_start, stack_end,
4590 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4591 text_end, exec_data_start, exec_data_end, text_offset,
4592 exec_data_offset, data_offset, stack_offset). They're
4593 superseded the more general build_section_table and
4595 (get_exec_file): Mention the `file' command.
4596 (read_memory_check): Rename to memory_error, and only call it
4597 in the case of an actual error.
4598 (read_memory, write_memory): call memory_error.
4599 (core_fetch_registers): Register section name is ".reg".
4601 coredep.c: Remove a bunch of crud now that all this file does
4602 is pull the registers out of a core file.
4603 (fetch_core_registers): Rewrite to actually work, I hope.
4605 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4606 Replace index() with strchr(). Remove all the pre-BFD macro
4607 definitions for accessing the symbol file.
4608 (struct dbx_symfile_info): Encapsulate the information that
4609 dbx_symfile_init needs to pass to dbx_symfile_read in this
4612 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4613 dbx_symfile_discard): Rearrange symbol file reading to divide
4614 the format-specific part from the format-independent part,
4615 leaving the format-independent part such as file name expansion
4616 and opening in symtab.c. This replaces
4617 partial_symbol_file_open and partial_symbol_file_read.
4618 Symbol_file_read, add_file, add_file_target_command,
4619 add_file_addr_command move to symtab.c. Pass an explicit
4620 "mainline" flag for when reading the main symbol table, rather
4621 than relying on the offset address to be zero or nonzero.
4623 (dbx_symfile_read): Don't allow void *'s to be printed as
4625 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4626 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4627 macro" debug version really work.
4628 (read_dbx_symtab): Remove unref'd parameter inclink.
4629 Avoid swapping N_SLINE symbols, for speed.
4630 Merge N_TEXT!N_EXT case with the other external symbol
4631 definitions' case. Add comments.
4632 (start_psymtab): Allocate the symfile name in the psymtab on
4633 the psymbol_obstack, rather than using the caller's storage.
4634 (end_psymtab): Only allocate a dependencies list if there are
4636 (psymtab_to_symtab_2): Use BFD when reopening file to read
4637 its symbols for real.
4638 (read_struct_type): Add FIXME comments where it needs work
4640 (read_huge_number): Add FIXME about overflows.
4641 (read_range_type): Add FIXME about comparing a long to 1<<32.
4643 * coffread.c: Minor changes to move things closer to the new
4644 regime with symtab.c and dbxread.c Major work is still needed
4647 * exec.c (exec_file_command): Remove old variables (see core.c
4649 (xfer_memory): If memory transfer is right at the end of a
4650 section, don't lose.
4652 * findvar.c (get_saved_register): If value is in a real
4653 register, LVAL is lval_register, not lval_memory.
4655 frame.h: Declare print_sel_frame and record_selected_frame.
4657 gdb-int.texinfo: New file, for GDB internals documentation.
4658 Very simple, unformatted doc of cleanups is there for now.
4660 gdbcore.h: Remove obsolete variables that described a.out
4661 section addresses and offsets. (See core.c above.)
4662 Declare fetch_core_registers and registers_fetched.
4664 getopt.c: Declare char *alloca(); even on SPARC.
4666 infcmd.c (run_command): Call target_kill rather than
4668 (step_command, next_command, stepi_command, nexti_command):
4669 Declare from_tty parameter even though we don't use it.
4670 (run_stack_dummy): argument BUFFER is a char array, not
4671 a pointer to REGISTER_TYPE.
4672 (finish_command): using_struct_return needed a value *,
4673 not a struct symbol *.
4675 * infptrace.c (child_xfer_memory): To avoid dependency on
4676 where sections are in memory, try PT_WRITE_D and if that fails,
4677 try PT_WRITE_I. Most Unixes don't care which you use.
4679 * infrun.c (step_resume_break_shadow): Change to array to
4680 match other breakpoint shadow storage.
4681 (clear_proceed_status): Pass address of bpstat to
4682 bpstat_clear, not the bpstat itself.
4683 (child_create_inferior): FIXME comment about if the child
4685 (start_inferior): Remove old function.
4686 (child_open): Use target_kill rather than kill_inferior.
4687 (wait_for_inferior): Ditto.
4688 (insert_step_breakpoint, remote_step_breakpoint): Use
4689 new step_resume_break_shadow.
4691 * inftarg.c (child_wait): If all child processes die,
4692 pretend that the one being waited for exited with signal 42.
4694 * main.c (command_line_input): When scanning for comments,
4695 don't coredump on unclosed quotes.
4696 (quit_command): Use target_kill rther than kill_inferior.
4697 (_initialize_main): Rename class_user from "user" to
4700 * printcmd.c (print_command_1): Initialize "fmt" if no format
4701 is specified by the user.
4702 (print_frame_args): Only add to args_printed if we are
4703 actually fetching args from the stack (avoiding undefined
4705 (_initialize_printcmd): Remove bogus \{ from string.
4707 * remote-eb.c (eb_open): Avoid coredump on no argument.
4709 * remote-nindy.c: Bring out of Intel environment into new
4710 target environment. Remove all conditional compilation on
4711 I80960. Massive hacking throughout.
4712 (nindy_xfer_inferior_memory): New routine stolen from
4714 (nindy_create_inferior): New routine pieced together, probably
4715 not quite working yet.
4716 (nindy_ops): New target_ops struct for nindy.
4718 * remote-vx.c: Use write_memory rather than target_write_memory
4719 to get error checking.
4720 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4722 (vx_create_inferior): Use target_terminal_ours...
4724 * signame.c (_initialize_signame): Always initialize, since
4725 we need the table for things other than psignal.
4727 * solib.c (solib_add): Use symbol_file_add, not add_file.
4728 (solib_address): Return boolean result rather than struct
4729 pointer which nobody else knows the type of.
4731 * sparc-tdep.c, valops.c: Use write_memory rather than
4732 target_write_memory, to get error checking.
4734 * stack.c (locals_info, catch_info, args_info,
4735 get_selected_block, frame_command, up_command): Use
4736 target_has_stack, rather than have_inferior_p or
4739 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4741 * symfile.h: New file, defining the interface between the
4742 generic and object-file-specific symbol reading code.
4744 * symtab.c: Move generic symbol-reading interface to symtab.c,
4745 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4746 table to map BFD targets to symbol-reading modules in GDB.
4747 Change index to strchr.
4748 (lookup_struct_elt_type): Use error() rather than hand-made
4749 simulations thereof.
4750 (lookup_partial_symbol): Speedup slightly when length == 0.
4751 (symbol_file_add): New function.
4752 (symbol_file_command): Call it.
4753 (symfile_open, symfile_init): New function.
4754 (add_file_target_command, add_file_addr_command): moved from
4757 * target.c (target_command): use target_kill.
4759 * target.h (target_files_info): Don't declare, never called
4762 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4763 files to determine stack end address.
4765 * valarith.c (value_x_binop, value_x_unop): Change error message
4766 to be more useful. Pass proper argument to value_struct_elt.
4768 * valops.c (value_assign): FIXME comment that long long
4769 bitfields will break here.
4771 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4772 Update `make saber_gdb' to work better.
4774 * TODO: A woman's work is never done.
4776 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4777 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4778 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4779 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4780 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4781 valops.c, valprint.c, exec.c: Lint.
4784 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4786 Continuing Intel 960 port merge of GDB.
4788 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4789 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4790 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4791 Wack over "make depend" so it handles files in subdirectories
4792 vx-share, nindy-share, bfd, and in the current directory.
4794 * blockframe.c (get_prev_frame_info): Remove fatal error
4795 if stack not defined.
4797 * core.c (core_open, core_detach): New functions that handle
4798 the old "core-file" command as "target core" and "detach" instead.
4799 (core_file_command): Call them.
4800 (core_xfer_memory): Use common routine xfer_memory.
4802 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4803 dbxread now uses bfd for everything but symbol reading itself.
4804 BFD internals are used to drag out the relevant file offsets.
4805 (partial_symbol_file_open): Change args all around for BFD.
4807 * symtab.c: Rename "value" to "val" everywhere, so we can
4809 (symbol_file_command): New command, moved from dbxread.c
4810 and coffread.c. It uses BFD to read the file, then vectors
4811 based on its type, to dbx or coff symbol readers.
4812 * symtab.h: Extern a few vars for symbol_file_command.
4814 * target.h: Breakpoint takes a char * save area, not a char **.
4816 * valprint.c (val_print): When unpacking bitfields, offset
4817 the address in gdb of the value, if it is declared with a shorter
4818 type. Remove the last "runtime kludge test" of host byte order.
4820 * utils.c: Remove old my_bfd_read routine.
4822 * stack.c (frame_info): Use target_has_stack. Print program counter
4823 register's actual name rather than "pc", since it's called the
4824 "ip" (instruction pointer) on the i960 (sigh).
4826 * target.c (target_command): Add command for selecting a target
4827 type and calling its open routine. This is used for initiating
4828 communication with a particular target, in a generic way.
4830 * tm-i960.h: Update for modern gdb. Remove semicolons from
4831 various macros. Handle reading struct return convention, and
4832 error-out attempts to return structs with the "return" command.
4833 Be sure gdb doesn't think we know how to call functions in the
4836 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4837 to i960_xxx in lower case.

4852 (wait_for_inferior): Clear saved register values before target_wait,
4853 so target_wait can set some of them if convenient.
4855 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4856 Return success indicator, not void.
4857 (child_xfer_memory): Avoid fetching initial word if we'll
4858 overwrite it anyway.
4860 * infcmd.c (attach_command): Use new generic target open routine.

4917 Thu Apr 19 09:54:28 PDT 1990
4918 Add 'reset' command.
4920 Wed Apr 18 09:48:07 PDT 1990
4921 After opening remote tty, wait for 1 second to go by without input
4922 from it before trying to talk to NINDY (fixes problems with the
4923 Heurikon HK80/V960E).
4925 Mon Apr 4 16:33:05 PDT 1990
4926 Some output was not being suppressed in 'batch' mode.
4928 Thu Mar 22 15:31:11 PST 1990
4929 Ask user if old symbol table should be deleted when new file is

4967 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4968 - made disassembly interface identical to that in gdmp960.
4972 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4974 * target.h: Allow targets to stack. Add target_has_memory,
4975 _registers, etc. Restructure memory access and "info files"
4976 to walk the target stack.
4977 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4978 target.c: Change tables to match target.h.
4979 * inflow.c (child_mourn_inferior): pop child_ops.

4983 * remote-eb.c: New memory regime, new info files.
4984 * remote-vx.c: New memory regime, new info files. Now use
4985 separate targets for VxWorks attachment to machine, and
4986 actually running a process under VxWorks, since one has
4987 stack & execution & regs and the other doesn't.
4988 * remote.c: New memory regime, new info files.
4989 * sparc-xdep.c (fetch_core-registers): New memory regime.
4990 * target.c: New routines and support for stacked targets,
4991 new memory regime, new info files regime.
4994 Generalize section handling for an arbitrary number of sections,
4995 including use of the new BFD (binary file) library.
4996 * gdbcore.h: Add struct section_table.
4997 * exec.c (build_section_table): Iterate all sections and
4998 record what gdb needs to know about them.
4999 (exec_command): Use it.
5000 (exec_xfer_memory): Use the table.
5001 (exec_files_info): Print the table.
5002 * core.c (core_file_command, core_xfer_memory, core_files_info):

5010 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
5012 * inferior.h (attach_flag): Export.
5013 * infcmd.c (run_command): use new target_create_inferior.
5014 * infrun.c (child_create_inferior): Don't return result.

5023 * core.c (core_file_command): Display the frame where the core
5028 * remote-vx.c (target_command): Merge in target command from
5029 targ-vx.c. A few other cleanups.
5031 * TODO, Projects: Lots more stuff to do...
5033 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
5035 Massive changes to wall off the remote-debugging interface
5036 behind a function vector. The port to handle VxWorks targets
5037 is also part of this.
5039 All files: Replace references to renamed functions,
5040 remove references to remote_debugging, remove references to
5041 have_include_file, have_core_file in favor of target_has_stack,
5042 target_has_memory, etc.
5044 * Modularize the breakpoint interface.
5045 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
5046 a breakpoint instruction.
5047 breakpoint.c: struct breakpoint's shadow_contents now sized as
5049 (insert_breakpoints): Vector to target to install breakpoints.
5050 (remove_breakpoints): Vector to target here too.
5051 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
5052 sparc-tdep.c (single_step): Use new breakpoint interface for
5053 the single-step breakpoints.
5054 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
5055 New file, contains routines to insert and remove breakpoints by
5056 reading out the old contents and later replacing them. This is
5057 how ptrace breakpoints work, and many remote systems as well.
5059 * tm-vxworks68.h: New config file, overrides a few things for
5060 Wind River's preferences.
5062 * target.h: New file, for transfer vector used to talk to the
5063 inferior (child, attached, core, exec, remote, etc). All accesses
5064 to the thing being debugged should come through these vectors.
5065 target.c: New file, routines to handle transfer vector.
5066 (various files): Add transfer vectors XXX_ops for the various
5067 targets and pseudo-targets (core files, etc) we support.
5069 * breakpoint.c (bpstat_stop_status): Further explorations of
5070 watchpoints and why things don't work all the time.
5071 (bpstat_alloc): New fn to allocate a bpstat and chain it.
5073 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
5074 the local gdbinit if it doesn't already have it.
5076 * core.c (core_ops): add and install.
5077 Allow core debugging without exec file.
5079 * dbxread.c (free_and_init_header_files): Merge two fns.
5080 (end_symtab): Free named symbol table when a new version comes in.
5081 (read_dbx_symtab): Relocate all kinds of symbols with base
5082 address. First step toward handling different text, data, bss
5084 (add_file_addr_command): Renamed add_file_command.
5085 (add_file_command): Vector to remote handler.
5086 Add "load" as an alias for "add-file" command.
5088 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
5089 non-returning functions.
5091 * exec.c: Add exec_ops, and push it as a target when an exec
5094 * infcmd.c (run_command): Pass executable file name and arg list
5095 separately when starting an inferior. Permit "run" when no exec
5096 file is specified, for VxWorks.
5097 (detach_command): Move to child_detach in inftarg.c.
5099 * inftarg.c: New file. Unix-child-specific routines, and the
5100 child_ops structure.
5102 * inferior.h (registers): Export "registers" as the way for
5103 target dependent register handlers to find gdb's local copy of
5104 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
5105 since it is now used by places that want wait_for_inferior to
5106 handle the grunge but want to see every trap from the inferior.
5108 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
5109 Eliminate remote_debugging hooks in terminal handling.
5111 * infrun.c: Replace start_inferior with child_create_inferior.
5112 Move all the hair of Unix shells and ptrace idiosyncracies into
5113 child_create_inferior, so remote handlers don't have to deal.
5114 Remove running_in_shell. Rename stop_after_attach to
5115 stop_soon_quietly, and use it in a few other places where we want
5116 to just call wait_for_inferior and get control back on the first
5117 trap. trap_expected now never takes a value > 1.
5118 (init_wait_for_inferior): Initialize static vars when a new
5121 main.c (gdbinit): Add new hook for .gdbinit file name, let
5122 it be overridden by config files as GDBINIT_FILENAME.
5123 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
5124 Both of these are used for VxWorks gdb.
5126 mcheck.c: rename include file "gmalloc.c" to avoid problems
5127 with system include file "malloc.c".
5129 param-no-tm.h: New include file, same as param.h but does not
5130 include the default "tm.h" file. This is used in files where
5131 the target is known, e.g. remote-eb.c or sparc-xdep.c.
5133 param.h: Now just a shell that includes tm.h and param-no-tm.h.
5135 remote-vx.c: New file, VxWorks remote debugging support. Uses
5136 RPC routines that are shared with the target system, in directory
5139 remote.c: Vectorize remote interface.
5141 source.c: Globalize source_path, and make an alias "l" for "list"
5142 since we now have the "load" command.
5144 sparc-xdep.c: Use new param-no-tm.h.
5146 symmisc.c (free_named_symtab): Add new function from Wind River.
5147 However, ifdef it out for now while we think about what it should
5150 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
5152 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
5153 non-Unix-children handle this with their own code in the target
5156 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
5157 source and target lists. Add vx-share to default list of include
5158 directories. Add new files to src and target lists: mem-break,
5159 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
5160 ${srcdir} versions of munch and createtags are used.
5162 * valops.c (find_function_addr): Split out of call_function.
5163 (call_function_by_hand): Rename call_function; this function
5164 calls functions in the target by laboriously patching the target
5165 word-by-word with the right stack, args, regs, etc.
5168 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
5170 Handle AMD 29000 a bit better.
5172 * remote-eb.c (readchar): Mask received char log to make it readable.
5173 (remote_start): Pass arguments down to executing program.
5174 Make startaddr unsigned.
5175 infrun.c (start_inferior): Accept args, pass them to
5177 infcmd.c (run_command): Pass args down to start_inferior.
5179 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
5180 the target object file format.
5181 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
5183 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
5184 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
5186 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
5188 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
5189 * TODO: We did a few things, we have more to do though.

5198 (sparc_push_dummy_frame): Simplify and fix what we push.
5199 (sparc_pop_frame): Slightly more hair here, deciding whether
5200 we are restoring a saved PC or returning to a return address in %i7.
5201 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
5203 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
5204 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
5205 * obstack.h (chunkfun): ditto.
5206 * defs.h (xmalloc, xrealloc): ditto
5208 * utils.c (quit): Grab the terminal from the child if necessary.
5210 * inflow.c (term_status_command): Rename to term_info, change
5213 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
5214 (is_delayed_branch): Speed up.
5215 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
5216 Still missing some float ops, and needs testing.
5218 * Support for input and output radixes other than base 10
5219 * defs.h (input_radix, output_radix): Declare.
5220 * expread.y (yyparse, parse_number): Handle changes of input
5221 radix, and ambiguous names-or-numbers in radixes >10.
5222 * printcmd.c (print_scalar_formatted): Print formatted hex
5223 numbers in varying column widths.
5224 * valprint.c (val_print): Use output_format to print scalar ints.
5225 (set_input_radix, set_output_radix, set_radix): Create.
5226 (set_output_radix): Set output_format from output_radix.
5227 (_initialize_valprint): add `set radix' but leave the others off.
5229 * main.c (execute_command): Let stupid questions be turned off.
5230 (_initialize_main): Handle "set stupidity", etc.
5232 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
5233 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
5235 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
5237 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
5238 bfd stuff is still screwed up, but with some manual work, it
5241 * breakpoint.c (bpstat_do_actions): Start over if a command
5242 proceeds the inferior, since the inferior will have stopped and
5243 will need to have its new stop-actions taken care of.
5245 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
5246 compiler fits, simplify it.
5248 * gdb.texinfo (directory command): Doc new dir command.
5249 source.c (directory_command): "dir" now puts things on the front
5250 of the path, moves dups up front, and handles multiple names
5251 on the command line, inserting each one in order. It also
5252 blows away cached line and full_filename info.
5254 * stack.c (backtrace_command): Skip "more stack frames follow"
5257 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
5258 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
5259 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
5260 The only odd one was Gould NP1, which had defined vprintf to
5263 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
5264 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
5265 variable, inspect_it.
5266 valprint.c (print_string, val_print): Use the global inspect_it
5267 to indicate whether to print in Epoch style or normal style.
5269 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
5271 * printcmd.c (call_command): add an alias for the "print" command
5272 which runs expressions and doesn't print the result if void.
5273 (print_command_1): implement it.
5275 * command.c: Remove #if 0'd code. Initialize all the fields
5276 in add_cmd (). Rename do_nothing_command to
5277 not_just_help_class_command, and make it externally visible.
5278 command.h: add user_commands to struct.
5279 * main.c (define_command): Don't overload c->function with a char
5280 string as well as a function pointer.
5282 * eval.c (evaluate_subexp): Reinstall tiemann changes to
5283 calling convention of value_struct_elt () that got dropped in
5286 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
5287 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
5289 * tm-sparc.h (POP_FRAME): replace some constants with defines.
5291 * sparc-xdep.c (store_inferior_registers): defer stores to regs
5292 until a good time (e.g. when we are about to run the child),
5293 saving ptrace calls.
5294 * infrun.c (proceed): handle DO_DEFERRED_STORES.
5295 * tm-sparc.h: define DO_DEFERRED_STORES.
5297 * sparc-xdep.c (store_inferior_registers): when storing float
5298 registers, don't store stack regs too. When storing the SP,
5299 however, DO store the stack regs too. This fixes a bug in which
5300 the dummy frame is not recognized when a call_function finishes,
5301 because its frame pointer (in the stack regs) was never
5303 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
5304 even though we don't know how to read them from an inferior.
5305 valops.c (call_function): Comment about storing SP.
5307 * infrun.c (save_inferior_status): Save away the original bpstat
5308 chain so it can be restored later. Install the copied version for
5309 use by whoever saved the status. It will be blow away by
5310 restore_inferior_status, and the original chain restored. This is
5311 important for people who have pointers into the original.
5313 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
5314 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
5315 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
5318 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
5320 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
5321 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
5322 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
5324 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
5326 * Merge Mike Tiemann's multiple inheritance changes from Sun.
5327 Store the baseclasses in a type struct starting from array element
5328 0 rather than from the unusual array element 1.
5330 dbxread.c: the above.
5331 (virtual_context): Add
5332 Read new debug information about which virtual function table
5333 a virtual function is from, and store it in fn_field.fcontext.
5335 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
5336 TYPE_FN_FIELD_STATIC_P.
5338 symtab.c: the above.
5339 valops.c: the above. Handle pointer casts of object *'s.
5340 (search_struct_method): Add.
5341 (value_struct_elt): First arg is now a pointer to a value, and is
5344 valprint.c: the above.
5345 values.c (value_virtual_fn_field): Add type arg. Handle
5346 offsetting to the proper object when calling virtual fns.
5348 (baseclass_addr): Add valuep arg.
5350 * README: Document the current state of BFD config (missing).
5351 * TODO, ChangeLog, Makefile.dist: Roll version.
5352 * WHATS.NEW: Add summary of changes since 3.5.
5354 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
5356 * dbxread.c (read_struct_type): Clear bit vectors whenever
5358 symtab.c (B_CLRALL): define.
5360 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5361 using == rather than =. Huh... This fixes the dreaded problem
5362 wherein builtin_type_int becomes TYPE_CODE_FLT.
5364 * core.c (info_files): Show the inferior pid.
5366 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5367 already knows how to look in the source directory.
5369 * Remove psymtab hair from many places. Remove duplicated code
5370 for searching symbol tables. Hide psymtabs from most places.
5371 Make it fast to get from a psymtab to its symtab.
5373 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5374 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5375 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5376 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5377 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5378 new symtab completely. New psymtabs get symtab pointer
5379 initialized to zero. Remove MI warning printf.
5380 symtab.h: Comments. Add psymtab to symtab pointer.
5381 (PSYMTAB_TO_SYMTAB): New macro.
5382 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5383 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5385 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5387 (print_frame_info): Avoid special-casing symbols that have not yet
5390 * source.c (open_source_file): Quick path if we have already
5391 located the source file by its full name.
5393 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5394 find_pc_psymtab. When a name is found in the misc function
5395 vector, search the symbol table for its mangled name, not the
5396 name that the user typed.
5398 * bfd.h: Fix missing comment terminators, make #endifs match.
5400 * valarith.c (value_less): Handle unsigned int comparisons.
5401 Add FIXME about pointer compares, which assume host and target
5402 pointers are the same.
5404 * command.c (do_nothing_command): lint
5405 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5406 fix comments on debug symbol format for visibility. Actually set
5407 visibility of symbols.
5408 main.c (echo_command): lint; use <readline/history.h>.
5409 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5410 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5411 pointing past end of allocated memory; saber complains.
5412 obstack.h: Declare the external functions that we use.
5413 valarith.h: use <string.h>
5414 solib.c (solib_add): lint.
5416 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5418 * main.c (initialize_main): Default info_verbose to off, now that
5419 symbol reading is fast.
5420 (quit_command): Avoid clobbering exec_bfd while quitting.
5422 * Initial BFD (binary file diddling library) merger:
5423 coffread.c: Change AOUTHDR to struct exe_hdr.
5425 core.c: initialize initialized data at compile time.
5426 (core_file_command): Move from coredep.c, convert to bfd.
5427 (xfer_core_file): Convert to bfd.
5428 exec.c (exec_file_command): use bfd routines.
5430 mips-tdep.c: Remove exec_file_command and friends.
5433 * coredep.c: (fetch_core_registers) Convert core_file_command to
5434 fetch_core_registers.
5435 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5437 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5438 (my_bfd_read): More bogosity, which I don't think we call.
5439 (program_name): Remove this atrocity asap!
5441 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5444 values.c: allocate_repeat_value was not clearing the
5445 optimized_out field.
5446 (value_static_field): minor stylistic fix (wrong macro was used).
5447 valops.c (value_struct_elt_for_address): didn't work for C++
5450 * signame.c (_initialize_signame): Initialize signal names once.
5452 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5453 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5454 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5456 * remote-eb.c: Support user-settable baud rates on the serial port.
5458 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5460 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5462 * tconfig/sun3os4: Remove warning about native assembler,
5463 since it also occurs in the xconfig file.
5465 * findvar.c (registers): Allocate some slop after `registers'
5466 to prevent stray accesses from trashing the next variable.
5468 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5469 on the sun-3, by changing the #ifdef from `sun3' (which is not
5470 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5471 vars, which happened to follow `registers' in the executable.
5473 * readline/history.c (history_search): Heed gcc-2's advice
5474 and parenthesize && inside ||).
5476 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5477 tm-29k.c: Insert FSF copyright headers.
5479 * remote-eb.c: Better comments.
5481 * Makefile.dist: Update to 3.91.6.
5482 * TODO: note PREPARE_TO_STORE problem.
5484 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5486 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5488 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5490 * infrun.c (wait_for_inferior, at end): Don't set up
5491 prev_* if the inferior no longer exists.
5493 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5494 CANNOT_EXECUTE_STACK.
5495 valops.c (call_function): Use it.
5497 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5499 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5500 infrun.c (wait_for_inferior, 2 places): Use it.
5502 * values.c (value_being_returned): Only use
5503 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5505 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5506 right thing for remote-eb.c.
5508 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5509 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5511 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5512 (FRAME_FIND_SAVED_REGS).
5514 * findvar.c ({fetch,store}_registers): Check for
5515 REMOTE_{FETCH_STORE}_REGISTER macro.
5517 * findvar.c (get_saved_register): Add argument lval and
5518 change meaning of argument addr.
5519 findvar.c: Change calls to get_saved_register to reflect
5520 new calling convention.
5521 valops.c (value_assign): Use get_saved_register instead of
5522 find_saved_register.
5524 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5526 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5527 an (uninitialized) pointer to one. Use "&" when passing it
5530 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5532 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5535 * coffread.c (symbol_file_command): Put semicolon after
5537 Put safe_to_init_tdesc_context in #if defined (TDESC).
5538 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5539 coffread.c: #include <sys/stat.h>.
5540 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5541 Add missing ')' in check for "lc%" and friends. Remove
5543 Declare read_one_sym() at top of file.
5544 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5545 MC68WRMAGIC can have the same value without causing a duplicate
5548 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5550 * Allow a Makefile to be built without building the
5551 tm and xm file links that screw up builds in subdirectories.
5552 This is done with `config.gdb none', then you can do things
5553 like `make gdb.tar.Z'.
5554 * tconfig/none: Config file for no target system
5555 * xconfig/none: Config file for no host system
5556 * config.gdb: If no TM or XM files are called out by the
5557 host or target file, don't make links for them.
5559 * cplus-dem.c: Add documentation.
5561 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5562 simple error, so the user's gdb doesn't crash due to some object
5563 file problem (e.g. somebody is rebuilding the file out from under
5566 * printcmd.c (print_address_symbolic): demangle the symbol.
5568 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5569 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5570 (alldeps.mak): sort and uniq all results from this; duplicates
5571 hose gdb.tar.Z link building. Remove RCS files from
5572 tconfig and xconfig. Add config files for sun386. Add
5573 a few odd files to OTHERS and HFILES.
5575 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5577 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5578 Roll version number to 3.91.5. Make lint work in bindir.
5580 * README: Document cross-debugging and new file structure.
5582 * blockframe.c: Lint. Include "value.h" to declare read_register.
5583 (find_pc_partial_function): remove duplicate line.
5585 * command.h: Lint. Declare error_no_arg and dont_repeat.
5587 * tm-news.h: Remove inadvertently duplicated stuff.
5589 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5590 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5592 * config.gdb: Allow `config.gdb host target' form. Clean
5593 up previous change that printed bogus messages when you just said
5596 * core.c: #include "command.h" for lint.
5599 * main.c: Remove some casts of enums. Lint.
5606 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5608 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5609 read it from memory. This will allow us to save ptrace calls
5610 eventually. Changed caller single_step too.
5612 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5613 that we aren't going to use, saving many ptrace calls, especially
5614 when watchpointing or single stepping. Use some #define's for
5616 (store_inferior_registers): Ditto.
5617 (core_file_command): Use some #define's for constants.
5619 * tm-sparc.h: Add #define's for some register numbers, so we
5620 can eliminate the use of random constants in sparc-xdep.c.
5622 * stack.c (frame_command, print_frame_info, up_command,
5623 down_command) Remove frame_changed, since it
5624 causes a bug and doesn't seem to do anything useful. In some
5625 places it was used as a flag, in others as a stack level (?).
5627 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5628 default is to use the portable (vprintf) version rather than the
5630 * xm-news.h (MISSING_VPRINTF): Add.
5632 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5634 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5636 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5637 about linking debugged programs -Bstatic in the sun?os4 config
5638 files in tconfig and xconfig subdirectories.
5640 * main.c (main): Remove unreached exit(0) now that we exit
5643 * Create TODO file for online bug list. There are too many
5644 "little" bugs to keep track of on paper.
5646 * Change Projects file to refer to bug-gdb@cygnus.com
5647 rather than kingdon@ai.
5649 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5651 * Makefile.dist (VERSION): 3.91.4 now.
5653 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5654 (condense_misc_bunches): Add sanity check that misc_count is
5655 the same as the number of symbols in the bunch.
5657 * coffread.c: rename init_misc_bunches. Pass an argument
5658 to condense_misc_bunches (a zero).
5660 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5661 every time we are called; don't rely on our caller to do it.
5662 (add_file): Remove call to init_misc_bunches.
5664 * mipsread.c: Only warn, don't error, if unknown symbol types.
5665 This keeps an old gdb from falling on its face if it sees newly
5666 extended symbol info. Rename init_misc_bunches.
5668 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5670 * Merge in changes from Per Bothner for DECstations and other
5671 MIPS stuff. The rest is Bothner speaking:
5673 The next message is a merger of Alessando Forin's mips port with
5674 mine. I've tried to use my good if biased judgment to get
5675 the best of both. It *does* need testing.
5677 Some of the changes are general, *not* mips-specific.
5680 Didn't believe in little-endian bit order.
5681 There are still inconsistencies about whether flags
5682 like BITS_BIG_ENDIAN are integer (#if ...) or
5683 boolean (#ifdef ...). I tried to paper over them.
5685 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5686 Moved some misc_function code that was common to
5687 {dbx,coff,mips}read.c to symtab.c.
5688 In the process, I think I cleaned things up a bit.
5689 At the same time, moved obsavestring and obconcat to symtab.c.
5692 Removed obsolete condense_addl_misc_bunches (use
5693 condense_misc_bunches(1) instead).
5696 Needed to include <sys/dir>, at least on DECstations.
5698 valops.c, mips-tdep.c, tm-mips.h:
5699 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5700 conventions (when STACK_ALIGN is insufficient).
5701 Needed on mips, where doubles need 8-byte alignment,
5702 but ints only need 4.
5705 Removed cruft that was not being used.
5706 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5709 Print $ before register-names (I think that makes things a little
5711 Never print two instructions, even if one delays.
5712 Removed hex-disassemble set_cmd. (This is not mips-specific,
5713 so I think the argument is whether it is generally worthwhile or not.
5714 I'm inclined to think not, given how easy it is to
5715 convert between radixes in gdb.)
5718 This is basically Alessando's code.
5719 It doesn't use obstacks; I changed it to use obstacks
5720 in a few minor places where using malloc causes a
5721 memory leak. (Probably, more places could/should be changed.)
5722 I added record_misc_function where it was missing.
5723 In symbol_file_command and add_file_command, I tried
5724 to make the code consistent with more recent versions.
5725 Minor sylistic changes in parse_procedure.
5726 Make a .gdbinfo. psuedo-symbol point back to the real
5727 procedure symbol (using the isym field).
5730 This is basically from my port, but with a lot of details
5731 and a number of routines merged in from Alessando's version.
5732 I basically used my code "raw" backtrace (use heuristics
5733 from the actual code, rather than symbol table info) - though
5734 the idea is Alessandro's. I feel my code is a little cleaner
5735 here, particularly in being a little more flexible, such as being
5736 able to handle gcc-produced code (which it now can).
5737 It also doesn't do frame caching (which is not useful
5738 more recent gdb versions).
5739 I also used my code for push_/pop_dummy, more or less.
5740 I tried to incorporate AF's code for testing sigtramp
5741 while backtracing; I probably got it wrong.
5742 Added mips_print_register, which tries to scrunch as much
5743 information as possible on a screen...
5744 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5745 under mips-pinsn.c), I don't see anything mips-specific here,
5746 and I don't see it being all that useful anyway.
5749 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5750 Use more register names (rather than hard-cases numbers).
5752 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5754 * Hack up 3.90.11 changes:
5756 * Makefile.dist (depend): parameterize $(GCC).
5757 Add solib.c and solib.o.
5758 (readline): Fix vpath for both absolute or relative SRCDIR.
5760 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5761 Also, let the part I didn't understand at least compile so
5762 I can test the rest. FIXME.
5764 * dbxread.c: Fix thinko using strcmp.
5765 (init_psymbol_list): declare static.
5766 (partial_symbol_file_open): Comment cleanups better, avoid
5767 cleaning up the string table since the caller will do that.
5768 Move the stat for mod time into symbol_file_command, temporarily.
5769 (There should be a mod time for each symbol file, eventually,
5770 to control its rereading. FIXME.)
5772 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5773 SunOS, which gives error for shared libs otherwise. (From
5774 Schaefer, probably FIXME needs work for portability.)
5776 * solib.c: Move #include "param.h" to work.
5777 Lowercase all the Uppercase Letters In the Messages.
5778 (find_solib): Clean up inferior_so_name for debug printouts.
5779 Allow no argument, to mean all shared libraries.
5781 * symmisc.c: include param.h to get CLEAR_SOLIB.
5783 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5785 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9

5829 Take code which is shared between symbol_file_command and
5830 add_file_command and put it into partial_symbol_file_{open,read}.
5831 Split add_file_command into add_file_command and add_file.
5832 Make psymtab_to_symtab read in the string table if the file
5834 Two new parameters to read_dbx_symtab and start_psymtab.
5835 tm-sunos.h: New file.
5837 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)

5854 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5856 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5858 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386

5875 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5877 config.gdb: If srcdir != ., create readline directory and
5878 copy a makefile into it.
5880 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5881 consistency with POSIX.
5883 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5884 when we exit its exp_valid_block.
5886 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5888 * Makefile.dist: Bump version to 3.91.3.
5890 * Clean up handling of breakpoint commands (somewhat).
5891 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5893 inferior.h: Add breakpoint_proceeded to inferior status struct
5894 and globals; save it and restore it.
5895 (clear_breakpoint_commands): Cleanup, remove old #define.
5897 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5898 (save_inferior_status, restore_inferior_status): handle it also.
5899 (proceed): Remove earlier code that set breakpoint_proceeded.
5900 It is now set only in clear_proceed_status.
5901 (clear_proceed_status): Cleanup, use bpstat_clear rather
5902 than clear_breakpoint_commands. No callers need the stop_bpstat
5903 between clear_proceed_status and proceed.
5905 infcmd.c: Add breakpoint_proceeded definition and comment.
5906 (cont_command, jump_command, signal_command): Move call to
5907 clear_proceed_status right next to call to proceed.
5909 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5910 caller's argument while running down the chain of breakpoints.
5911 Use new variable "breakpoint_proceeded" to determine when
5912 a command that it executes moves the inferior past the
5914 (bpstat_clear): Handle NULL argument.
5915 (bpstat_clear_actions): Avoid useless call to
5916 breakpoint_auto_delete.
5917 (delete_breakpoint): Clean up bpstat's that are pointing to
5918 the deleted breakpoint from the stop_bpstat chain.
5919 (breakpoint_auto_delete): Simplify.
5921 * Clean up handling of EOF, error on stdin, etc. This was
5922 prompted by a network problem that caused gdb to go into an
5923 infinite loop filling up its malloc'd memory.
5925 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5926 not clear_breakpoints_commands, which is now gone.
5927 (main): If command_loop returns (e.g. from EOF on stdin), do
5928 a quit_command (looping back to command_loop if quit_command
5929 doesn't really quit).
5930 (command_loop): check result from command_line_input and
5931 exit if it returns NULL, rather than passing the NULL to
5933 (gdb_readline): Free malloc'd result space before returning
5936 * utils.c (query): Handle C-d to mean "yes", just as if the
5937 input was not a terminal. Also avoid infinite loop if EOF
5938 occurs in mid-input-line before newline. This allows
5939 query to be used at EOF on stdin with reasonable results.
5941 * infrun.c (proceed): Set breakpoint_proceeded.
5943 * values.c (value_as_long): Avoid infinite recursion for enums.
5944 (_initialize_values): Fix typo in help msg (kingdon).
5946 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5947 RL_LIB for linking. This allows -lreadline for linking
5948 and nothing for dependencies, once readline is a real library.
5950 * config.gdb: Jim Kingdon: give useful error message if the
5951 host or target type is not recognized.
5953 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5954 it just defines it. Dumb, but deal with it.
5956 * Jim Kingdon suggests:
5957 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5959 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5961 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5963 * Clean up Bothner's changes.
5965 * blockframe.c (clear_pc_function_cache): New function.
5966 * blockframe.c: remake cache_pc_function_* static.
5967 * dbxread.c (symbol_file_command): remove references to
5968 cache_pc_function_* variables.
5969 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5970 * printcmd.c: Avoid kludging a global variable (addressprint)
5971 to avoid printing the address of a string twice. Instead,
5972 pass the format letter 's' down low enough that it can be seen
5973 to avoid this problem.
5974 (print_formatted): Pass format arg to value_print.
5975 (restore_addressprint): Remove function.
5976 (do_examine): Avoid hacking addressprint, cleanups and such.
5977 (print_frame_args): Add a comment to a Bothner change.
5978 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5979 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5980 to wipe out the values cached in blockframe.c.
5981 * symtab.c (find_method): Add comment saying how big you must
5982 allocate to be "big enough". Per being terse again.
5983 * valprint.c (val_print): Handle format letter "s" to print
5984 strings without addresses. Add comment to vtbl printing code
5985 which casts with wild abandon. Rearrange reference-printing
5987 @0xaddr: value (print w/addressprint)
5988 value (print w/~addressprint)
5989 @0xaddr (parameter lists w/addressprint)
5990 or nothing (parameter lists w/o addressprint)
5992 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5994 * Merge more changes from Per Bothner:
5996 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5997 annoying) that I tried to improve it. Here are my suggestions.
5999 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
6002 Do automatic de-reference when taking the address of a reference.
6004 Don't deref_ref when printing parameter lists.
6006 More attempts at treating refernences properly.
6008 In val_print, if deref_ref==0, don't print dangling " = ".
6010 Add COERCE_REF macro, which de-references an REF.
6012 * Merge changes from Per Bothner:
6014 * Fixed (Sony news)-specific configuration problems.
6015 * Fixed other problems with using vanilla pcc and libc (enum problems;
6016 assumption that vsprintf exists).
6017 * Some major speed-ups (finc_pc_partial_function now caches a match;
6018 parsing avoids duplicate symbol_lookup calls).
6019 * Changed handling of baseclasses (no longer use baseclasses field
6020 of struct type, use the first n_baseclasses fields instead).
6021 * Various minor changes/fixes, most C++-related.
6024 Cache the most previous match from find_pc_partial_function.
6025 (Save both low and high ends of matching function's pc range.)
6026 This speeds up the loop of infrun.c:wait_for_inferior quite
6027 a bit, and makes step/next commands much zippier.
6029 Added an enum->int cast (otherwise, some compilers barf).
6031 No longer set baseclass offset to 0, since multiple
6032 inheritance now mostly works.
6033 Added a number of casts, to shut up compiler warnings
6034 (after stabs where made enums, not ints).
6035 When discarding a symbol table (in symbol_file_command),
6036 must clear the cache introduced in blockframe.c.
6037 Don't convert $vtbl_ptr_type to vtbl any more.
6038 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
6039 Mask off sign bit emitted by g++ for virtual table offset.
6040 Set voffset to -1 (not 1) for static member functions.
6042 Changed parsing/lexing of names to avoid doing symbol lookup twice
6043 (once when lexing to determine symbol class, once for real).
6044 Now only call symbol_lookup once. Fields of 'this' win especially big.
6046 Subpress printing addr twice in the case of 'x/s addr'.
6048 lookup_basetype_type is no longer used.
6049 Add find_methods as recursive helper function to decode_line_1.
6050 This allows multiple inheritance to work.
6051 Also, once one or more matches has been found, do not look in
6052 base-classes. (Baseclass methods would be overridden, anyway.)
6054 Removed baseclasses array in struct type.
6055 Instead of using baseclasses[i], use fields[i-1].
6056 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
6057 Changed sign convention of voffset (previous was inconsistent).
6059 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
6061 Used to assume existence of vsprintf. Re-written to not need it
6062 if HAVE_VPRINTF is undefined.
6064 typecmp was too pessimistic. Made it less so.
6066 Don't print space after address.
6067 If vtable points to a misc symbol (with 0 offset), print it,
6068 since that indicates the actual class of the object.
6069 Changed ype_print_derivation_info to use new inheritance
6070 scheme (without baseclasses vector).
6072 In value_primitive_field, fixed some bugs left over from previous set of fixes.
6073 Also, changes needed because TYPE_BASECLASSES were removed.
6075 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
6077 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
6080 If there is no path set, and the symbols don't indicate what directory
6081 a file was compiled in, look in the current directory. But either
6082 a path or a known compilation directory will prevent this.
6085 Three independent bug fixes:
6086 * Remove the #if 0 block that breaks some stuff.
6087 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
6088 adapt gdb to either SunOS 4.0.* or 4.1.
6089 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
6092 Instantiate the class T when looking for methods in it. (Tiemann@sun)
6095 (type_print) Demangle the name being printed.
6096 (type_print_base) Handle botched demangling without coredump (tiemann).
6099 (check_stub_method): Document routine.
6100 (tiemann) fix bug for no-arg functions
6101 Avoid clobbering beyond end of malloc'd storage.
6102 Terminate the argument list properly.
6104 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
6106 * Changes merged by John Gilmore:
6109 In breakpoint_1, use new print_address_symbolic instead
6110 of find_pc_partial_function. (This forces use of assembler-level
6111 addresses, and avoids misleading non-mangled source-level names.)
6113 Generalize ansi argument such that -1 means skip arglist totally.
6114 Removed global variable print_ansi_qualifiers (which made
6115 code non-reentrant), in favor of extra explicit arguments
6116 to internal routines.
6118 Add new helper function print_address_symbolic.
6119 Use find_pc_misc_function instead of find_pc_partial_function
6120 (since we want assembler-level symbols here).
6122 Print unknown function as just "f (...)", not "f (...) (...)".
6123 Use new fputs_demangled explicitly.
6125 Fixed a typing violation (problem: value.h cannot be imported
6126 without renaming many variable in this file).
6127 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
6128 decode_line_1: Moved forward some never-reached code.
6129 Made decode_line_2 skip function prologues correctly.
6131 fputs_filtered should not demangle by default.
6132 Add new fputs_demangled to demangle on demand..
6134 Change value_struct_elt to use value_primitive_field (using recursive
6135 utility function search_struct_field). This allows foo.bar to work
6136 for multiple inheritance (so far only for data fields).
6137 Change check_field in the same way (recursive helper function
6138 to support multiple inheritance).
6139 (Note: there are more of these problems that I haven't fixed.
6140 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
6141 value_of_this: 'this' symbol name is now just "this", note "$this".
6143 Don't print static members.
6144 Avoid printing "members of <type>" if there are none.
6145 Simplified type_print_derivation_info by merging duplicate code.
6146 Remove useless blank lines in type_print_base (ptype command).
6148 Added declaration of new routine value_primitive_field.
6150 Added value_primitive_field which is generalized version of
6151 value_field that can handle multiple inheritance (non-zero offsets etc).
6152 Re-implemented value_field to call value_primitive_field.
6154 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
6156 * infcmd.c -- insert else to avoid 'delete env' coredump when you
6157 delete the whole environment. Karl Berry reported the bug.
6158 * source.c - fix openp to avoid //'s in filenames, which
6159 trigger an Emacs bug causing it to not be able to find files
6160 when running gdb in a window.
6161 * dbxread.c - zap the #if 0 that botches the add-file code.
6162 It seems to work a lot better without all the code commented out.
6164 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
6166 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
6169 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
6171 * Makefile - added a ${CFLAGS} to a couple of entries,
6172 added remote-sa.sparc.c
6173 * added remote.sa-sparc.c, a modification of remote.c
6174 which conducts a dialog directly with the SparcStation prom.
6175 * breakpoint.c, infrun.c, sparcdep.c added
6176 remote_insert_breakpoint(), and remote_remove_breakpoint()
6177 to breakpoint.c instead of directly writing breakpoint instructions.
6178 * sparcdep.c on remote_debugging,there is no need
6179 to remove signle step breakpoint instructions.
6180 * main.c added "-epoch" flag and "int epoch_interface" to main.c
6182 * printcmd.c - epoch interface sends lisp expressions to open up
6183 epoch windows on inspection.
6184 * valprint.c - added arrayprint, and addressprint and made adding
6185 format controls easier
6186 * wait.h added a couple of undef's because we were getting
6187 complaints about WSTOPSIG and WTERMSIG begin redefined.
6190 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
6192 * symtab.c (decode_line_1): Add support for handling method stubs

6197 * values.c (baseclass_addr): Run loop from INDEX+1 to
6198 N_BASECLASSES; otherwise, we can still get into a loop.
6199 @@ This should be restructured to use a cleaner search strategy.
6201 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
6203 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
6204 abbreviation "Tt" for tags which have the same name as their
6207 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
6209 * symtab.c (list_symbols): add ability to set breakpoints on all
6210 the functions which match a particular regular expression.
6212 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
6214 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
6215 should print ANSI qualifiers (such as `const' and `volatile').
6216 All callers changed to call with ANSI == 1, except from
6217 `check_method_stub', which uses old-style syntax.
6219 * symseg.h (struct fn_field): Remove unneccessary `args' field.
6220 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
6222 * values.c (check_stub_method): New function.
6224 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
6226 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
6227 * valprint (type_print_base): Ditto.
6229 * symtab.c (gdb_mangle_typename): New function.
6231 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
6233 * breakpoint.c (catch_command): New function. Provides a
6234 mechanism to set breakpoints based on catch clauses.
6235 (disable_catch): Similar, but disables breakpoints on catch
6237 (delete_catch): Similar, but deleted breakpoints on catch clauses.
6239 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
6241 * blockframe.c (blockvector_for_pc): New function.
6242 * blockframe.c (block_for_pc): Changed to call
6243 `blockvector_for_pc' and get the block itself.
6245 * stack.c (catch_info): New function. Prints info about
6246 exceptions which can be caught in the current frame.
6247 * stack.c (print_frame_label_vars): New function. Similar to
6248 `print_frame_local_vars'.
6249 * stack.c (print_block_frame_labels): Prints out labels that are
6250 defined in this frame. These labels are exceptions that can be
6253 * dbxread.c: Updated to handle N_CATCH symtab types.
6255 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
6257 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
6258 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
6259 when printing the type.
6261 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
6263 * valprint.c (val_print): Use `baseclass_addr' to access the
6264 baseclasses pointed to via the derived class object at VALADDR.
6266 * values.c (baseclass_addr): New function. Casts derived pointers
6267 to baseclass pointers taking virtual baseclasses and multiple
6268 inheritance into account.
6270 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6274 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6276 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
6277 exp_valid_block field correctly.
6279 * infrun.c (wait_for_inferior): When checking "don't even think
6280 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
6281 also check step_resume_breakpoint.
6282 Insert breakpoints and continue (not step) if
6283 step_resume_break_address != NULL, even if another_trap.
6284 If trap_expected and we enter sigtramp, then set up a
6286 If trap_expected is set when we hit the step_resume_break,
6288 When calling resume and trap_expected says tell resume to step
6289 (2 places), also check step_resume_break_address.
6291 * infrun.c (wait_for_inferior): Don't set
6292 prev_{pc,sp,func_{start,name}} before calling wait ().

6299 * infrun.c (wait_for_inferior, after check for trap_expected > 1):
6300 Restore old code which distinguishes between trap_expected and
6301 running_in_shell, just make the latter take any non-TRAP signal,
6304 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
6306 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.

6331 char. Add macro VALUE_OPTIMIZED_OUT.
6333 * i386-pinsn.c: Change from Eirik Fuller to write to stream directly
6334 instead of stuffing things in buffers (oappend, etc).
6336 * breakpoint.c (bpstat_do_actions): If *BSP is set to NULL by
6337 execute_command, exit both loops.

6346 m68k-xdep.c, coredep.c: Wrap in #if !defined (RDB).
6348 * valops.c (value_struct_elt), values.c (value_static_field):
6349 Change error messages to remove references to `info methods'.

6363 Mon Apr 23 10:42:21 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6366 findvar.c (get_saved_register): New function.
6367 findvar.c: Rewrite code which called find_saved_register to
6368 call get_saved_register instead.
6370 Sun Apr 22 14:47:51 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6372 * valprint.c (val_print): Change error message printed when
6373 the type has TYPE_FLAG_STUB set.

6406 * coffread.c: Define L_LNNO32 if not defined.
6407 (enter_linenos): Use it.
6408 * blockframe.c: Add INIT_FRAME_PC hook and use it in
6409 get_prev_frame_info.
6410 m-m88k.h: Use INIT_{FRAME_PC,EXTRA_FRAME_INFO} to do tdesc stuff.
