3 Add tracking of object files (that contain symbols) to gdb.
4 This includes a "struct objfile" that owns symtabs and psymtabs
5 that were read in from that binary file.
7 * symfile.h: Add struct objfile. Add pointer to the objfile
8 into the struct sym_fns.
9 Replace global `symfile' and `symfile_mtime' with
10 `symfile_objfile'. Add global object_files chain.
12 * symfile.c: Move param.h above symtab.h.
13 (sort_misc_function_vector): Add.
14 (syms_from_objfile): Was syms_from_bfd.
15 (symfile_open): Now returns objfile.
16 (allocate_objfile): New.
17 (free_objfile): New, replacing free_all_.*symtabs.
18 (symfile_init): Takes objfile arg, puts it in sym_fns result.
19 (reread_symbols): Searches whole chain of objfiles.
20 (allocate_symtab): Takes objfile as new parameter, chains them.
21 Handle INIT_EXTRA_SYMTAB_INFO.

24 * dbxread.c: Make more errors into complaints.
25 (push_subfile, pop_subfile): Move to buildsym.c.
26 (dbx_symfile_read, dbx_symfile_init, fill_symbuf, read_dbx_symtab,
27 start_psymtab, psymtab_to_symtab_1, read_ofile_symtab,
28 dbx_psymtab_to_symtab, ): Use bfd ops, don't use file descriptor.
29 Pass objfile. Change callers.
30 (fill_symbuf, SWAP_SYMBOL): Take bfd as arg.
31 (read_dbx_symtab): Just wipe out new symbols, not all, on error.
32 (end_psymtab): Blow away psymtab if empty.
33 (process_symbol_pair): Swallow into read_ofile_symtab.
34 (process_one_symbol): Use push_context and pop_context.

52 * coffread.c (end_symtab, read_coff_symtab): Take and use objfile arg.
53 (read_coff_symtab): Cleanup by freeing objfile, not all symtabs.
55 * mipsread.c (read_mips_symtab, parse_partial_symbols, parse_fdr,
56 new_psymtab, new_symtab): Take and use objfile arg.
58 * dwarfread.c (scan_compilation_units, start_psymtab,
59 process_dies, end_symtab, dwarf_build_psymtabs,
60 read_lexical_block_scope, read_func_scope, read_file_scope): Take
61 and use objfile argument.
62 (psymtab_to_symtab_1, read_ofile_symtab): Don't take or use file
63 descriptor. Use BFD internal functions instead.
64 (end_symtab): Call global allocate_symtab.

84 Thu Nov 7 18:26:15 1991 Steve Chamberlain (sac at rtl.cygnus.com)
86 * Makefile.in: link with libiberty after libreadline, since
87 readline might want something in libiberty.
88 * m88k-xdep.c: Fixed the register offsets in the ptrace_user
89 struct for BCS 88k machines.
90 * xm-m88k.h: don't define USIZE if already defined.
91 * configure.in: Added delta88 target.
93 Thu Nov 7 04:51:19 1991 John Gilmore (gnu at cygnus.com)
95 * am29k-pinsn.c, am29k-opcode.h: Fix decoding of mtacc, dmac, fmac.
97 * tm-*.h: Remove READ_DBX_FORMAT, COFF_FORMAT, and
98 READ_MIPS_FORMAT, which have been unused since BFD. Still
99 remaining is COFF_NO_LONG_FILE_NAMES.
100 * tm-sun3.h, tm-altos.h: Remove detritus accidentally left from
101 function calling code moved to m68k-tdep.c.
103 Wed Nov 6 17:21:59 1991 John Gilmore (gnu at cygnus.com)
105 * coffread.c: Eliminate c_nsyms in favor of c_naux.
106 Complain if no auxents on .bf and .ef FCN symbols, and assume
107 lots of line numbers.
108 (init_linenos, enter_linenos): Use a sentinel at the end of the
109 read-in linenos, to make for a fast, safe loop-end test.
111 Wed Nov 6 02:54:08 1991 Steve Chamberlain (sac at cygnus.com)
113 * coffread.c (read_coff_symtab): coffread used to rely on the
114 x_sym.x_misc.x_lnsz.x_lnno field giving the # of linnos in a
115 function. Two of the formats I'm using (29k and 88k) don't seem to
116 set it. Ths patch to fcn_last_line and (enter_linenos) is an
117 attempt to use the actual size of the linno table in the file to set
118 the number of linenos to process.
120 Tue Nov 5 22:47:46 1991 Steve Chamberlain (sac at cygnus.com)
122 * Makefile.in: put a - infront of the mv y.tab.c c-exp.tab.c and
123 mv y.tab.c m2-exp.tab.c, so that if bison is used, and the files
124 are created in place, so the mv fails, then the make continues.
126 Tue Nov 5 16:47:47 1991 Per Bothner (bothner at cygnus.com)
128 Add C++ as a separate language.
129 * defs.h (enum language): Add language_cplus.
130 * dwarfread.c (end_symtab): Support language_cplus.
131 * c-exp.y: Add new struct language_defn cplus_language_defn.
132 Don't set c to be the default language (see main.c).
133 * c-exp.y (yylex): Only look for field of this if
134 language is C++. (First difference from C!)
135 * language.c: Add case branches for C++ (currently, all
136 the same as C). Also, add c++ to "usage" note for "set lang".
137 * valprint.c (typedef_print). Add case branches for C++.
138 * main.c (main): New way to set initial language: Look at
139 file extension of psymtab containing main(). (Same as we
140 do for symtabs, but avoid loading the symtab yet.)
141 * symtab.c: New routine find_main_psymtab(), used by main()
142 to set initial language.
143 * symfile.c (allocate_symtab): Move code for mapping file
144 extensions-> languages to new deduce_language_from_filename().
146 Fix a C++ problem when looking for methods in super-classes.
147 There was confusion between base and derived types.
148 * valops.c (value_fn_field): Change function interface.
149 * values.c: Use new value_fn_field interface.
151 Mon Nov 4 10:49:33 1991 Per Bothner (bothner at cygnus.com)
153 * infrun.c: Fixed typo in comment.
154 * utils.c: All the v*fprintf emulation is now in libiberty,
155 so we can get rid of some junk.
156 * xm-sun3os4.h, xm-sun4os4.h, xconfig/decstation, xconfig/i386sco,
157 xconfig/sun3os4, xconfig/sun4os4: Don`t need HAVE_STRSTR any more.
158 * m68k-pinsn.c (print_insn_arg): Support BB/BW/BL
159 type operands, as used by branch instructions.
160 * gmalloc.c: Fix prototype of memcpy.
161 * elfread.c: Comment out register_addr, since it conflicts
162 with the one in coredep.c.
163 * buildsym.h: Remove extern declarations of two functions
164 that are really static in buildsym.c.
165 * tm-mips.h: Add symbolic names for more registers.
166 * mips-xdep.c (store_inferior_registers): Use new register names.
167 * xm-mips.h: Simplify REGISTER_U_ADDR, since it is now
168 only used for core files, not ptrace. Therefore,
169 the KERNEL_U_ADDR hack is no longer needed.
170 The mapping to ptrace number is now in in mips-xdep.c.
171 * mips-xdep.c: Define REGISTER_PTRACE_ADDR (using the
172 mapping from the old REGISTER_U_ADDR), and use it
173 in {fetch,store}_inferior_registers.
174 * mipsread.c: Rename #include ecoff.h to new name coff-mips.h.
175 * mips-tdep.c (mips_push_dummy_frame, mips_pop_frame):
176 Save/restore FP regs correctly (?).
177 * dbxread.c: Remove duplicate define_symbol and type_synonym_name
178 (these had been previously moved to buildsym.c).
179 Hence, define_symbol becomes extern instead of static.
180 * buildsym.c (read_struct_type): Comment out bogus handling
181 of C++ operator methods. Minor hacking of reading of class
182 contexts. Make define_symbol non-static, so dbxread.c can call it.
184 Fri Nov 1 11:05:47 1991 John Gilmore (gnu at cygnus.com)
186 * mipsread.c (read_mips_symtab, read_the_mips_symtab): Use real
187 filename with error messages.
188 * stack.c (frame_select_command): Rename to select_frame_command
189 to avoid "fr" and "fra" having nonunique completions.
190 * symfile.c (sort_symtab_syms): Ignore sort of zero symtab *.
191 (symfile_init): Print file format name when unable to handle it.
192 (free_named_symtabs): Use BLOCKVECTOR rather than obsolete BLOCKLIST.
193 * symmisc.c (free_symtab): Only free linetable if nonzero.
194 * symtab.h: Remove obsolete BLOCKLIST macros.
196 Thu Oct 31 18:12:43 1991 Stu Grossman (grossman at cygnus.com)
198 * infrun.c (wait_for_inferior): another stepi/nexti fix. Ensure
199 that stop_step is 1 at bottom of main loop. I don't know why this
200 needs to be done, but it helps me sleep better at night.
202 Sun Oct 27 18:18:39 1991 Stu Grossman (grossman at cygnus.com)
204 * main.c (initialize_history): Read history after reading all
207 Sun Oct 27 14:09:25 1991 John Gilmore (gnu at cygnus.com)
209 * buildsym.c: Break out initial malloc sizes.
210 (record_line): Record directly in a subfile. Alloc on demand.
211 (compare_line_numbers): Add from xcoffread.c.
212 (end_symtab): New params say whether to sort pendings and
213 linetable. Patch block stabs if defined. Shrink linetable before
214 allocating the symtab.
215 * buildsym.h: Delete line_vector* and prev_line_number. Add
216 global_stabs and file_stabs for xcoffread.
217 * dbxread.c (start_subfile): Move to buildsym. Change above calls.
218 * symtab.h: LINETABLE(symtab) can now be null. Zap LINELIST.
219 * symmisc.c, symtab.c: Cope with null LINETABLEs.
221 * blockframe.c: Pass fromleaf to INIT_EXTRA_FRAME_INFO.
222 * tm-29k.h, tm-88k.h, tm-i960.h, tm-irix3.h, tm-mips.h, tm-pyr.h,
223 tm-sparc.h: Accept fromleaf parameter.
224 * c-exp.y (yyerror): Pass error message if given.
225 * configure.in: Add rs6000 host and target.
226 * inflow.c (new_tty): O_NOCTTY kludge for RS/6000.
227 * symfile.h (entry_point): Add.
229 Sat Oct 26 00:16:32 1991 John Gilmore (gnu at cygus.com)
231 * buildsym.c: New file. Breaks out symbol-table-building routines
232 from dbxread.c, so they can be shared with xcoffread.c.
233 * buildsym.h: New file. Declarations for buildsym.c users.
234 * dbxread.c: Remove large chunks into buildsym.c.
235 * Makefile.in: Add buildsym.c and buildsym.h.
237 * symfile.c (syms_from_bfd): New routine.
238 (add_symbol_file): Call it to do the real work.
239 (syms_from_bfd): Initialize entry_point before calling symfile_init.
240 * symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
241 Avoid declaring or setting entry_point (symfile.h & symfile.c cope).
243 Fri Oct 25 18:59:32 1991 Per Bothner (bothner at cygnus.com)
245 Various fixes to improve g++ debugging.
246 * symtab.h: Add is_const and is_volatile flags for each method.
247 These are bit fields - take their space from voffset,
248 which shrinks to 30 bits. Since voffset is now a bitfield,
249 make it unsigned for portability. This changes its interpretation
250 slightly: Static methods now have voffset 1 instead of -1,
251 and virtual offsets start at 2, not 1.
252 * symtab.c: Renamed gdb_mangle_typename to gdb_mangle_name,
253 since it now returns an entire magled method name, not just
254 the type part. This avoids some duplication.
255 It also allows us to correctly mangle const and volatile
256 methods (using the new is_const and is_volatile bit fields
258 * valprint.c (type_print_base), values.c (check_stub_method):
259 Simplify by using new gdb_mangle_name.
260 * values.c (value_headof): Fix to correctly handle single
261 inheritance (actually two fixes, either of which suffices).
262 * dbxread.c (read_struct_type): Handle const and volatile
264 * dbxread.c (read_struct_type): Yet one more place where
265 we must handle '\\' continuations.
266 * valprint.c (vtbl_ptr_name): Add final '\0'.
268 Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com)
270 * tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of
271 short return values for sparc and 68k. Patch from Paul Eggert.
273 * coffread.c, coredep.c, i386-xdep.c: install patches for
274 SysV/386 3.2 from Mauro DePalma.
276 Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
278 * core.c (core_file_info), exec.c (exec_file_info): Print file
279 type. Use printf_filtered.
281 * valops.c (value_fetch_lazy): Avoid 0-length fetches.
283 Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
285 * dwarfread.c: Add casts to remove compiler warnings.
287 * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
288 tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
289 tm-sun3.h: Remove locally duplicated code for calling functions
290 in the inferior. The only differences were in the specific trap
291 vectors used and whether or not an fpu was present. These are
292 now handled by appropriate definitions of BPT_VECTOR and
293 HAVE_68881 respectively. Other minor obvious cleanups.
295 * valops.c: Correct a minor misspelling.
297 * utils.c: Remove local BSD/USG hacks that are now in libiberty.
299 * dwarfread.c: Remove prototype for dwarfwarn. Does not work
302 Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
304 * stack.c (frame_command): Always print. Use new
305 frame_select_command to select a frame without printing.
307 * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
309 Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
311 * dwarfread.c: New file for DWARF debugging format support.
313 * elfread.c: New file for ELF object file format support.
315 * procfs.c: New file for SVR4 /proc (process file system) support.
317 * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
320 * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
322 * xm-m68k.h: New file for host machines with m68k cpu.
324 * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
325 Add elfread.o and dwarfread.o to OBS.
327 * symfile.h: Add "elf" to list of supported formats in comment.
329 * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
330 types to gdb, builtin_type_long_double, builtin_type_complex, and
331 builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
332 TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
333 TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
334 TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
335 types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
337 * infrun.c: When using SVR4 /proc interface instead of ptrace(),
338 call proc_set_exec_trap() to setup child to stop at first instruction.
340 * inftarg.c: When using SVR4 /proc interface, call proc_wait()
343 * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
344 supply_fpregset(), and fill_fpregset(), which are machine
345 dependent support routines for SVR4 /proc interface.
347 * utils.c: Add warning_setup() and warning(). Warning() behaves
348 the same as error() except that it returns normally rather than
349 jumping back to command level. Modules that don't want to call
350 warning() for some reason, but want to produce their own warnings,
351 can call warning_setup() to ensure compatibility with the way
352 warning() and error() deal with the terminal.
354 * symtab.c: Make internal errors produce more useful messages.
356 * tm-68k.h: Move code that is duplicated in almost every single
357 m68k based machine's configuration files to this common file.
358 Duplications in the configuration files still need to be removed
361 * infrun.c (child_create_inferior): System V versions must call
362 setpgrp() with no arguments, to comply with prototyping typically
365 * munch: Add support for SVR4 style nm output.
367 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
368 file specific fields from the partial symbol table structure and
369 replace them with a pointer to private data for each different
370 flavor of object file reader to initialize appropriately.
372 Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
374 * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
377 * mipsread.c (fixup_undef_type): New function. If a struct /
378 union / enum is defined in a header file but nowhere else used,
379 (by typedefing, pointer referencing or declaration) the mipsread code
380 builds the complete tree for the structure but leaves its code as
381 TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
382 Guess its type based on the details of the members.
384 Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
386 * infrun.c (wait_for_inferior): Check return value from
389 Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
391 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
392 by my last edit to this routine.
394 Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
396 * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
397 FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
398 the values before putting them into the dummy code. (From Peter
401 Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
403 * configure.in: added ebmon target.
405 Wed Oct 16 22:49:58 1991 John Gilmore (gnu at cygnus.com)
409 * Makefile.in: Roll VERSION to 4.2.
410 * README, TODO, WHATS.NEW: Update.
412 * core.c (core_open): Improve error message for bad file.
413 Pass .reg virtual memory address to fetch_core_registers to help
414 it find the registers in the core-file header.
415 * coredep.c (fetch_core_registers): Take new argument, use it,
416 and pass it to register_addr to locate the block of registers.
417 * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
419 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
420 Sequent N_FN_SEQ like everybody else's N_FN.
422 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
423 * tm-i386v.h: #endif guck.
424 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
425 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
426 * xconfig/tahoe: Add REGEX, which seems to be missing.
428 * coredep.c: Add <sys/types.h> for SCOnix.
429 * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file.
430 * printcmd.c (print_formatted): Flush output before disassembly.
432 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
434 * doc/refcard.tex (sec "Working Files"): consistent metavars and
435 other improvements, due to comments by François Pinard
436 (pinard@iro.umontreal.ca)
438 * doc/gdb.texinfo (appendix "Installing GDB"): changes in
439 configure, and improvenets related to Pinard's refcard comments
441 Tue Oct 15 08:45:12 1991 John Gilmore (gnu at cygnus.com)

479 * blockframe.c (inside_main_scope, inside_entry_scope): New.
481 * copying.awk: Filter formfeeds out of copying & warrantee.
482 Make them available as `show copying' and `show warrantee' also.
483 * main.c (print_gnu_advertisement): Advt `show' commands.
485 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)
487 * mach386-xdep.c: Even when cross-compiling, leave in the
488 core-file reading code.
489 * core.c (get_core_registers): Avoid coredump if no .reg section.
491 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
493 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
494 This avoids coredumps under `set print object on' in value_headof
495 (called erroneously by value_from_vtable_info) for `p &struct'
496 or `p *struct'. From Peter Schauer.
498 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
500 * Makefile.in: Roll version to 4.1.2.
501 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
502 size from BFD (but, FIXME, we don't yet read external nlists's and
503 convert them to internal nlists's before handling them -- we still
504 assume they have the same size and alignment.) Use SET_NAMESTRING
506 * exec.c (exec_file_command): Move dead coff-encapsulation code
508 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.
510 Fri Oct 4 22:30:06 1991 John Gilmore (gnu at cygnus.com)
512 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
513 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
515 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
517 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
518 * mips-xdep.c (store_inferior_registers): Don't try to
519 write the (pseudo) FP.
520 * mipsread.c (parse_partial_symbols): Improved algorithm for
521 setting pst->texthigh.
523 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
525 * doc/Makefile: make TEXINPUTS include . everywhere
527 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
529 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
530 vestiges of typevectors, which were for symsegs and are no longer
531 used. (From a question by Eliot Dresselhaus
532 <dresselh@RFT30.nas.nasa.gov>).
534 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
536 * dbxread.c, coffread.c: static-ize functions that were
537 gratuitiously external. (From Fred Fish.)
539 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
541 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
542 until it is large enough.
544 * dbxread.c (read_type): Handle error case slightly better.
545 Make complaint message not C++-specific.
547 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
549 * infrun.c (wait_for_inferior): Fix step/next so that you only
550 stop at the beginning of a new line. This fixes various problems
551 with for loops, nested if-else's and switch statements.
553 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
555 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
556 between symtabs and psymtabs become ordinary error()s.
558 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
559 properly, making "end pc" correct in shared lib psymtabs.
560 (From Guy Harris <guy@auspex.com>.)
562 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
564 * dbxread.c: Enable, but soften, const_vol_complaint.
565 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
566 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
567 should be file-scope, not global.
568 (read_struct_type): Remove ancient multiple-inheritance warning.
569 (read_range_type): Check base type, complain & patch if undefined.
570 * stack.c (frame_info): Demangle the function name in `info stack'.
573 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
575 * eval.c (evaluate_subexp_for_address): Don't use
576 TYPE_POINTER_TYPE directly (it might be zero if this type has
577 never had a pointer created before); use lookup_pointer_type.
578 * symtab.c (lookup_method_type): Arguments were swapped in all
579 callers, so fix it here. I'm amazed this worked at all!
581 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
583 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
584 "bss" rather than "data" symbols, but which still conflict.
587 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
588 * core.c (core_files_info): Shorten output.
589 * exec.c (exec_files_info): Ditto.
590 (build_section_table): Ignore zero-length sections.
591 * language.c, printcmd.c: Lint.
592 * language.h (get_frame_language): Declare.
593 * saber.suppress: update.
594 * stack.c (find_relative_frame): Remove complex code that was
595 #if 0'd, stick with simple code. Lint.
596 * saber.suppress: Update a bit.
597 * symfile.c (add_symbol_file_command): Add "?" to question.
598 * utils.c (parse_escape): Avoid \a due to bdead compilers.
599 * value.h: Declare typedef_print.
601 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
604 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
605 (Reported by Mark Peek <mark@imagen.com>.)
607 * solib.c (solib_map_sections): Relocate all sections, even
608 though only the text section's size is tracked. Mark ld_text
609 for eventual elimination as we generalize to N sections.
611 * infrun.c (wait_for_inferior): Don't check if the PC is in a
612 call_dummy if we were stopped by a random signal that is being
613 passed to the program. This produced wierd results when calling
614 functions in the inferior and signals (e.g. SIGALRM) were in use.
616 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
618 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
619 Bugfix from Paul Eggert <eggert@twinsun.com>.
620 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
621 * valprint.c (print_floating): Print 9 digits for IEEE floats.

630 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
634 * Makefile.in (VERSION): Set to 4.1.
635 * language.c (set_language_command): Print useful help message,
636 and restore the language string after giving help.
637 * valprint.c (typedef_print): Print typedef in C or M2.
638 * symtab.c (list_symbols): Use it.
639 * main.c (main): Avoid any output before (gdb) prompt when -q.
640 * language.c (set_language_command): Handle errors by restoring
641 the language string to its current state (fix from A. Beers).
642 * doc/gdbint.texinfo: Roll in information from README. Rearrange
643 "how to install" and "how to print the doc" stuff so it drops
645 * configure.in: Rename rtpc CPU to romp to match config.sub.
646 * README, WHATS.NEW, TODO: Update for gdb-4.1.
648 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
650 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
651 autoloading shared libs, copyright etc on GDB startup, clean up $_
652 and $__ index refs, set/show listsize and related updates to list
653 cmd. New host/target configs.
655 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
657 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
658 from main Makefile.in version definition
659 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
661 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
663 * doc/gdb.texinfo: merge new language-switching and lang-specific
666 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
668 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
669 compilers (which may lack stddef.h).
671 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
673 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
674 N_WARNING are the same except for the N_EXT bit, so just use their
675 values alone, rather than OR-ing them with N_EXT.
677 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
679 * mipsread.c (parse_lines): Deal with negative extended line
682 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
683 global symbol conflicts.
685 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
687 * .gdbinit: Move 'set complaints' to top, so it runs even in
688 case we aren't debugging GDB.
689 * language.c (_initialize_language): Fix type check and range
690 check documentation strings.
691 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
692 language.c can use it. (Though language.c should really not be
693 handling warnings/errors the way it does, FIXME.)
694 * symtab.c (lookup_primitive_type): const lint.
696 Bugfix from Peter Schauer:
697 * source.c (lines_to_list): Make signed, to avoid comparison
698 going unsigned and complaining that -3 is too high for 21 lines.
699 * stack.c (lines_to_list): Ditto.
701 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
703 * Makefile.in (HFILES): Add minimon.h.
704 (VERSION): Roll version number to 4.0.95.
705 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
706 New rules for building distributions. Normal distribution
707 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
708 one level up from here; it calls make-proto-gdb.dir to build a
709 directory `proto-gdb' which is an image of the release. The old
710 `gdb.tar.Z' rule still works too.
711 * config.sub, configure: Roll in latest from ..
713 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
715 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
716 new-target, and new-config chapters; fix minor typos; come closer
717 to usual GNU markup conventions for @file @samp @code @var.
719 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
721 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
722 * mipsread.c (parse_partial_symbols): Enter the name of all
723 structs/unions... into the psymtab so we can access them if the
724 symtab is not read in.
725 * mips-tdep.c: Remove some unneeded #includes.
726 * xconfig/dec3100: Add HAVE_STRSTR.
728 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
730 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
731 * c-exp.y, m2-exp.y: Lint.
732 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
733 * valprint.c (val_print_fields): Check for stub type.
734 * mipsread.c (_initialize_mipsread): Avoid using
735 builtin_type_void at initialize time.
736 (mipscoff_symfile_read): use it now.
738 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
740 Merge multiple-language support, and partial Modula-2 support,
741 from Andrew Beers <beers@cs.buffalo.edu>.
743 * i387-tdep.c: New file, consolidates most 80387 support,
744 and eliminates host dependency on double<->extended conversions.
745 * i386-xdep.c, symm-xdep.c: Remove most 387 support.

758 (read_dbx_symtab, case N_DEFD): Ignore.
759 (read_enum_type): Recognize FALSE/TRUE enum as Modula-2 BOOLEAN.
760 (read_range_type): Rename MAX_OF_TYPE to MAX_OF_C_TYPE, etc.
761 #if 0 out its uses, though, since they set a dead value.
762 * coffread.c (end_symtab): Use allocate_symtab.
763 (process_coff_symbol): #if 0'd for functions and params as above.
764 (read_enum_type): Recognize Modula-2 BOOLEAN.
765 * symtab.c (add_param_to_type): #if 0'd function to add a
766 parameter type to a function type's field list.

837 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
839 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
840 entries are enclosed herein. Not all of these changes
841 have been merged into the master GDB sources -- check the
842 ChangeLog above here for the merge log.
844 Mon Jun 3 17:05:45 EDT 1991
846 m2-exp.y Created. Tested outside of GDB for a few days. Proper
847 operators were added, C specific operators and tokens
848 removed. yylex() revamped to some extent. Still things
849 missing from the grammar, such as sets.
850 Tested for two weeks in GDB v3.5.
852 Tue Jun 11 17:23:48 EDT 1991
854 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
855 so they are built-in. Sort of a hack.
857 Fri Jun 14 12:53:51 EDT 1991
859 m2-exp.y Added range checking for numeric constants. Any numeric
860 constant is assumed to be of builtin type INTEGER unless:
861 (1) it is octal or hexadecimal, in which case it is a
862 CARDINAL; (2) it is too big to fit into an INTEGER, in
863 which case it is a CARDINAL.
864 eval.c Added simple range checking for +, -, and * on integers.
865 Doesn't work very well for *, since 6 * 1,000,000,000 =
866 1,705,032,704, which fails the simple test of result >=
867 first_operand, no matter in what order the operands are.
869 Tue Jun 18 14:11:30 EDT 1991
871 Broke the parser into parts, one containing the C grammar and the other
872 containing code to be shared by all of the grammars.
874 The following files no longer exist:
879 The following files were added:
881 c-exp.y (The C grammar)
882 m2-exp.y (The Modula-2 grammar)
883 parser-code.c (Code that is shared by the above grammar)
887 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
888 now necessary to use the Bison compiler compiler, since it
889 will generate function/variable prefixes other than yy.
891 Tue Jun 18 16:47:49 EDT 1991
893 symtab.[ch] Added the external variable working_lang, than holds the
894 value of the current working language.
895 Added the ennumerated type language_mode, with the values
896 language_auto and language_manual, the former meaning that
897 GDB sets working_lang as needed, and the latter meaning
898 that the value of working_lang is totally under user
900 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
901 REAL, BOOLEAN and CHAR. Also added the type codes
902 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
903 utils.c Added set_language_command and show_language_command to
904 implement the GDB support commands "set language" and
906 expression.h A number of identifiers were added to the type exp_opcode
907 to facilitate Modula-2 builtin functions, integer
908 division, and array indexing.
910 Wed Jun 19 13:25:58 EDT 1991
912 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
913 if the language specified by working_lang requires the use
914 of strict typing of expressions. Eventually, even this
915 will be able to be changed by the user.
916 Added the macro RANGE_CHECK, which evaluates to non-zero
917 if the language specified by working_lang requires the
918 checking of a value against the domain of its type.
919 Eventually, even this will be able to be changed by the
921 language.[ch] Predicates involving types (simple_type, ordered_type,
922 same_type, integral_type, numeric_type, character_type,
923 boolean_type, float_type) are added. These predicates are
924 based on the current value of working_lang, and are handy
927 Wed Jun 19 15:39:34 EDT 1991
929 eval.c Added the function type_array_rank which computes the rank
931 valarith.c Added the funtion value_bool, which when given a integer
932 value.h value (ie. struct value *) as an argument, it returns a
933 boolean value (ie. struct value *) true if that integer
934 is non-zero, and a boolean value false otherwise.
935 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
936 will print out properly.
938 Wed Jun 19 16:36:34 EDT 1991
940 valops.c Added the function value_capitalize, which returns it
941 value.h argument capitalized if its argument is a lowercase
942 letter, or the argument unchanged if its argument is not a
944 valarith.c Added the function range_check_p, which returns non-zero
945 value.h if its value argument is between the integral bounds upper
947 Added the function range_check_enum_p, which makes sure
948 that its value argument is a valid member of the domain of
950 Added the function range_check_range_p, which makes sure
951 its value argument lies between the upper and lower bounds
952 of its type argument, which must be a ranged type.
953 Added the function check_array_index, which range and type
954 checks an index of an array.
955 Added the function value_multi_subscript, which computes
956 array[idx1,idx2...idxN], given a value array and an array
957 of values representing indicies.
958 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
959 unpack_long to work with TYPE_CODE_BOOL and
962 Wed Jun 19 18:04:08 EDT 1991
964 symtab.c Stored pervasive types in a structure and make
965 lookup_pervasive_type() a lookup function that was based
966 on working_lang. If lookup_pervasive_type() returned
967 non-zero, then that value was returned (a fix, since
968 before it simply wouldn't return the pervasive type.)
969 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
970 non-zero if the language specified by working_lang means
971 "conversion" when it says "cast".
972 valops.c Added the function value_real_cast(), which performs a
973 value.h *cast*, not a *conversion*, which is what value_cast()
974 does when it can. In particular,
975 value_cast(<float_type>,4) = 4.0, while
976 value_real_cast(<float_type>,4) = some mess.
977 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
978 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
979 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
980 and MIN on integral types. *NOTE*: These are currently
981 hardcoded to work only if there are 8 bits per storage
983 eval.c Made logical functions call value_bool to return a
984 properly typed boolean value, based on working_lang.
986 Thu Jun 20 11:55:27 EDT 1991
988 valprint.c Types now print out in a Modula-2 fashion. This works for
989 the cases when the type is printed out step-by-step, that
990 is, it doesn't work when the name of a structured type
991 (which includes the keyword "struct", etc.) is simply
993 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
994 since type specifications in C and Modula-2 are very
995 different. The C printing of a type is very recursive,
996 whereas in Modula-2 it is generally very simple. C has
997 type prefixes and suffixes, which have no real analogue in
998 Modula-2. Maybe type_print() should call a language
999 specific type printer. This is also advantageous if we
1000 compile GDB to exclude some of the languages. We'll just
1001 leave those functions out.
1003 Thu Jun 20 16:57:10 EDT 1991
1005 dbxread.c When reading the complete symbol table in (via
1006 psymtab_to_symtab()), the number and types of function
1007 arguments are added to a function type. define_symbol()
1008 calls add_param_to_type() to accomplish this.
1009 Assumption: when we come across a function definition
1010 (N_FUN symbol with an 'f' or 'F' in the name), its
1011 arguments will appear before another function definition.
1012 When a function is found, a pointer to its type is placed
1013 in the global in_function_type. Changes that
1014 add_param_to_type() makes are to this global.
1015 valprint.c The type of a function now includes (for Modula-2) the
1016 types of its parameters.
1017 eval.c Type checking and a check for the proper number of
1018 arguments is now done for function calls. Not sure of the
1019 impact this has on C++ member function yet.
1021 Thu Jun 20 19:58:48 EDT 1991
1023 valprint.c Rewrote the type printer. Broke it into two language
1024 specific parts, adding the functions type_print_m2() and
1026 An unfortunate consequence is this: if you debugging a C
1027 program in Modula-2 mode (why?), info types does not work
1028 well with regular expressions, since the types are printed
1029 out in Modula-2 terminology, but stored in C terminology.
1030 language.[ch] Added the functions new_type_last(), type_keyword(), and
1031 type_sep() to aid in the printing of typedefs.
1032 symtab.c Made the printing of typedefs as language independent as
1033 possible through calls to new_type_last(), type_keyword(),
1036 Fri Jun 21 11:50:26 EDT 1991
1038 dbxread.c Check all incoming ennumerated types. If it looks like
1039 Modula-2's BOOLEAN type, then change the type_code of the
1040 type to TYPE_CODE_BOOL so we can process it as a boolean
1042 valprint.c Replaced some of the 0x%x with calls to sprintf and
1043 hexformat() in val_print().
1044 language.[ch] Added the function hex_to_string(), which converts its
1045 integral argument to a hexadecimal number (format is
1046 language based) and returns the result as a string.
1048 Mon Jun 24 12:25:07 EDT 1991
1050 valprint.c Some functions call type_print_1() directly, instead of
1051 value.h using type_print(), so they can specify where (column) to
1052 print things. Since type_print() takes care of language
1053 dependence, that needs to be called first. Added a
1054 parameter depth to type_print() (so it is now like
1055 type_print_1). Changed type_print to type_print_at, and
1056 made type_print a macro that passes a depth argument of
1058 symmisc.c Changed all calls to type_print_1 to calls to
1060 Makefile.dist Made it possible to build GDB for a specific set of
1061 depend languages. Do this by passing a definition for the macro
1062 LANGS to make. LANGS should be a string containing a
1063 space-separated list of language names (ie. LANGS="c m2").
1064 The default is to build all languages. Note that grammar
1065 files must follow the naming convention of <lang>-exp.y.
1066 gdb.lang This holds the current value of the LANGS macro. It is
1067 examined every time make is called, and is updated if
1069 eval.c Added #ifdef _LANG_<lang> to these files.
1070 expread.c Still need to add them to dbxread.c and coffread.c.
1078 Mon Jun 24 16:33:11 EDT 1991
1080 language.[ch] Added the functions hexformat_pre() and
1081 hex_to_string_pre(), which take a prefix argument to
1082 include in the format string. Thus, hexformat_pre("08") will
1083 return "0x08x" (if the working language is language_c).
1084 Made hexformat() and hex_to_string() calls to the above
1085 with "" as the prefix argument.
1087 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
1088 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
1089 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
1090 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
1091 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
1092 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
1093 valprint.c, vax-pinsn.c
1095 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
1096 calls to hexformat() and hex_to_string(). Format strings without
1097 the leading "0x" were ignored.
1099 depend Updated to take the above into account.
1102 Tue Jun 25 15:27:18 EDT 1991
1104 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
1105 and type_check_t to keep track of the current state of
1106 range and type checking.
1107 main.c Added the variables range_mode, range_check, type_mode,
1108 and type_check to record the current state of range and
1109 type checking. Added initialization code to main().
1110 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
1111 the above variables.
1114 Tue Jun 25 17:57:08 EDT 1991
1116 dbxread.c process_one_symbol() updates the variable (enum language)
1117 source_lang based on the extension of the filename
1118 contained in the N_SO sybmol that started this symtab.
1119 When end_symtab() is called, the value of source_lang is
1120 put into the language field.
1121 stack.c select_frame() sets working_lang (and possibly type_check
1122 and range_check) to the language field of the symtab
1123 associated with the frame that is selected if working_mode
1124 is language_auto. If working_mode is language_manual, a
1125 warning is printed and working_lang is not set.
1126 language.c Added the function set_type_range(), which sets the value of
1127 type_check and range_check (if their modes call for
1128 automatic setting) based on the current value of
1129 working_lang. A non-zero argument will cause the current
1130 settings to be output.
1133 Wed Jun 26 14:51:40 EDT 1991
1135 eval.c Added range checks on assignment.
1136 m2-exp.y Added the grammar for sets to the language. Currently,
1137 these do not do anything except print an error message.
1139 Wed Jun 26 17:01:04 EDT 1991
1141 m2-exp.y Added the ability for parse_number() to parse negative
1142 numbers. A global flag is set upon encountering a unary
1143 minus. This was done to make, for example, 1 parse as a
1144 CARDINAL, and not as an integer, per Wirth's examples in
1145 Programming in Modula-2 ed.4.
1146 valprint.c Added support for "set radix 2" by then setting
1147 output_format to 't'.
1148 eval.c Implemented range checking on subrange types. Added calls
1149 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
1150 Implemented MIN and MAX for ennumerated types. The
1151 minimum value of an ennumerated type is defined by Wirth
1152 as the first identifier, and the maximum as the last.
1153 m2-exp.y Made octal numbers ending with "B" be characters and those
1154 ending with "C" be numbers, per Wirth's book. (p. 34)
1156 Thu Jun 27 14:11:52 EDT 1991
1158 stack.c select_frame() now only sets working_lang, it does not
1159 notify the user. If working_mode is language_manual, then
1160 a warning is issued once.
1161 main.c At the end of each call to execute_command(), working_lang
1162 is checked against the local static (enum language)
1163 current. If they differ and working_mode is
1164 language_auto, the new settings of language, type and
1165 range checking are printed out.
1166 stack.c Modified frame_info() to include the language of the
1167 current frame in the output of "info frame".
1168 language.[ch] Added the function language_str() which returns the name
1169 of the current language.
1171 Fri Jun 28 15:33:14 EDT 1991
1173 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
1174 the language. INCL and DECL currently cause an error,
1175 since sets are not implemented yet. INC and DEC are
1176 implemented as PREINCREMENT/PREDECREMENT with one
1177 argument, and as ASSIGN_MODIFY with two arguments.
1178 eval.c Added type checking to the above cases.
1179 value.h Added not_lval_constant to the lval_type ennumerated type.
1180 not_lval_constant means that the value is a constant
1181 value; that is 3 or 'a' or TRUE, not as in a constant
1182 identifier. This is used to help coerce numbers such as 3
1183 to either signed or unsigned numbers.
1184 valops.c Added the function value_coerce_constants() which coerces
1185 constant integers as following: if one is a constant and
1186 the other is not, the constant's type is set to the type
1187 of the other argument. If both are constants and one is
1188 signed, the other is converted to a signed constant.
1190 Sat Jun 29 17:26:29 EDT 1991
1192 valarith.c Added a better range checker. It now checks range
1193 (successfully) on integral operations [+-] (signed and
1194 unsigned) for any C sized type. Still does not work well
1195 for multiplication.)
1196 int_in_size() returns an integer that is coerced to fit into
1197 specified number of bytes.
1199 Mon Jul 1 13:04:14 EDT 1991
1201 language.[ch] Added the function binop_result_type(), which returns the
1202 builtin (struct type *) type that would be the result of a
1203 binop on the two values V1 and V2.
1205 Wed Jul 3 19:22:53 EDT 1991
1207 source.c Extended source_info() to include the source language in
1208 the output from "info source".
1210 Fri Jul 5 13:48:52 EDT 1991
1212 utils.c Moved the support functions for the GDB set/show commands
1213 dealing with language into language.c.
1214 language.c Added the function language_info(), which displays info
1215 about the current working language, type and range check
1216 settings. Called via the GDB command "info language".
1217 Added an initialization routine _initialize_language(),
1218 that sets defaults for the language, type and range
1219 variables and sets up the new GDB commands.
1220 main.c Language setup moved to language.c.
1223 Mon Jul 8 10:10:22 EDT 1991
1225 valarith.c Debugged the range checker for arithmetic. Still does not
1226 work for multiplication very well.
1228 Mon Jul 8 12:40:37 EDT 1991
1230 language.[ch] Added the function value_true() which returns non-zero if
1231 its argument represents a boolean true value.
1232 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1233 check the truth of an expression.
1235 Thu Jul 11 12:51:34 EDT 1991
1237 language.[ch] Added the predicate structured_type(), which returns
1238 non-zero if the argument is a structured type.
1239 Added the predicate pointer_type(), which returns non-zero
1240 if the argument is a pointer type.
1241 eval.c Added the ability to do addition and substraction on
1242 pointers and integers. This case simply bypasses the
1245 Thu Jul 11 14:41:42 EDT 1991
1248 Added the symbol N_DEFD (0x4a) which is a definition
1249 module dependency that is used by the GNU Modula-2
1250 compiler and the linker. It is not important to GDB,
1251 except that [dbx|coff|mips]read.c should ignore these
1254 Fri Jul 12 16:07:00 EDT 1991
1256 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1257 0 in val_print(). Also added statements to the else part
1258 to coerce type (argument to val_print) to a pointer type
1259 if it is an "array of unspecified length".
1260 valops.c Added the function value_m2_string(), which returns a
1261 (value) value which is a constant string, whose type is
1262 (ARRAY [0..n] OF CHAR). The length field of the type
1263 structure is set to zero, so it will be interpreted as an
1264 "array of unspecified length".
1265 stack.c Moved the language/frame mismatch check to
1266 main.c:execute_command().
1267 main.c The working language is recorded each time
1268 execute_command() is executed. If working lang has
1269 changed during its execution, then the new
1270 language/type/range info is printed out for the user. If
1271 the working language does not match the language of the
1272 frame, a warning is issued.
1274 Sat Jul 13 16:16:39 EDT 1991
1276 eval.c Moved all the type-checking stuff for operators to
1277 language.[ch] language.c. This is so we can keep language-specific
1278 stuff (like for what type operators are defined) in
1280 language.[ch] Added the function binop_type_check(), which checks to see
1281 if its two (value) arguments are type-compatible with its
1282 opcode argument. The opcode should represent an operation
1283 involving an operator. Also added the macro function
1284 unop_type_check, which calls binop_type_check with a
1285 NULL second argument.
1286 expprint.c Added Modula-2 operators to the op_print_tab, so info
1287 expression.h break works correctly. Also added "op_string", which
1288 returns the string corresponding to the (enum exp_opcode)
1289 opcode that is its argument.
1292 Sat Jul 13 18:26:18 EDT 1991
1294 coffread.c Added code to record the type of function arguments with
1295 each paricular function. Code is very similar to that
1297 dbxread.c Moved add_param_to_type() to symtab.c
1298 symtab.[ch] Added function add_param_to_type() from dbxread.c
1300 *** NOTE: The above additions have not been tested.
1302 Mon Jul 15 12:50:47 EDT 1991
1304 langauge.[ch] Added the functions type_error and range_error, which work
1305 like error() except if the type/range mode is set to
1306 *_mode_warn, then they do not do a return_to_top_level(),
1307 but merely print a warning.
1308 Also changed [set|show]_[type|range]_command() to support
1309 the new "warn" feature.
1311 Thu Jul 18 17:50:54 EDT 1991
1313 mipsread.c Added code to record the type of function arguments with
1314 each particular function. Code is very similar to that
1317 *** NOTE: The above additions have not been tested.
1319 Fri Jul 19 11:19:10 EDT 1991
1321 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1322 UMIN_OF_SIZE, which when given a size of a numeric type,
1323 return the maximum and minimum value it can hold. UMAX...
1324 and UMIN... return the result for unsigned types.
1325 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1326 struct types. They call above macros.
1327 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1328 avoid a name conlict with the above.
1329 c-exp.y Added range checking on numeric constants in
1330 parse_number() for completeness.
1331 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1332 return 0 if working_lang is not language_c.
1334 Thu Aug 8 14:17:22 EDT 1991
1338 breakpoint.c Documentation strings of some commands changed to
1339 eliminate the references to the C language where
1342 Tue Aug 13 15:48:03 EDT 1991
1344 m2-exp.y Added qualified identifiers to the grammar. The semantics
1345 are slightly different from those of the GDB operator ::
1347 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1348 type_exp, where type_exp is any valid type expression.
1350 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1351 printcmd.c Modified ptype_command() so it actually parses the input
1352 (necessary for type expressions with scope qualifiers).
1353 Added the function ptype_eval() which expects an
1354 expression composed of one OP_TYPE element.
1355 *.[ch] Replaced all occurences of parse_c_expression with
1357 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1359 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1361 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1363 Small fixes from Peter Schauer:
1365 * infrun.c (child_attach): Lint.
1366 * solib.c (find_solib): Handle shared libs version 2.
1368 Small fixes from David Wood:
1370 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1374 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1375 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1377 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1378 chars_per_line is at maximum (user typed `set width 0'). Fix
1379 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1381 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1383 * coredep.c: include ptrace.h where necessary.
1384 * mipsread.c(parse_lines): fix unsigned char problem that was
1385 messing up line numbers on SGI's and possibly other MIPS based
1387 * infrun.c (child_create_inferior): use better test to check
1388 return val from setpgrp().
1389 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1390 for sgi/irix support.
1392 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1394 * mipsread.c (parse_symbol): Put non-static procedures
1395 in the global block.
1397 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1399 Patch together `text_start' and `text_end' for 29K port.
1401 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1402 variables and set them based on the exec file.
1403 * am29k-tdep.c: declare text_start.
1404 * valops.c (call_function_by_hand): declare text_end.
1406 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1407 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1408 because machines that do this will also have to know to
1409 set NEED_TEXT_START_END. Besides, it was a redundant way to
1411 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1412 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1413 NEED_TEXT_START_END.
1415 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1417 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1419 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1420 Pass MUNCH_DEFINE to munch whenever we run it.
1421 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1422 format string; use 0x%x instead.
1423 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1424 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1425 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1426 * inflow.c: Handle `short' process group IDs.
1427 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1428 and check for ptrace errors.
1429 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1430 (coff_symfile_init): Initialize text_bfd_scnum.
1431 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1432 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1433 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1434 Merge target arm case with other "easy" cases. Add target
1435 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1436 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1438 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1439 * munch: Cope with RT/PC putting fns in data segment.
1440 Restore ability to override `nm' by specifying MUNCH_NM.
1441 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1442 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1443 and remote-adapt. Remove encapsulated coff #define's (the
1444 support should go in BFD, and gdb shouldn't know or care).
1445 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1446 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1447 * tm-29k.h: Update BADMAG (though it should go away).
1448 Allow the register definitions to be overridden in another
1449 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1450 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1451 DUMMY_SAVE_GR96, for handling kernel calling conventions
1452 that use GR64+ rather than GR96+.
1453 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1454 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1455 overrides various things.
1457 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1458 child_attach does, making a clean stop in the newly attached
1460 * remote-eb.c: Lint.
1462 * coffread.c: Make coffread independent of any particular
1463 variant of COFF. Avoid #include-ing any particular one except
1464 internalcoff.h. BFD now passes key values for symbol reading
1465 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1466 and the symbol masks and shifts); use them.
1467 Remove obsolete end_of_text_addr.
1469 * exec.c: Remove unused include files.
1471 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1473 * Makefile.in (documentation targets): Pass $(M4).
1474 Bugfix from eggert@twinsun.com (Paul Eggert).
1476 * stack.c (down_silently_command): Check for stack existence.
1478 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1480 * Makefile.in (VERSION): Update to 4.0.3.
1482 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1484 * core.c (core_file_command): Print frame at coredump with
1485 its level number, by calling print_stack_frame.
1486 * frame.h: Add selected_frame_level, print_stack_frame.
1487 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1488 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1489 Change print_sel_frame and print_selected_frame callers to
1492 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1493 * symfile.c (free_named_symtabs): Ditto.
1494 * main.c (main): wrap_here needs an arg.
1495 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1496 (solib_add): Avoid noise.
1497 (solib_create_inferior_hook): Lint.
1498 (sharedlibrary_command): Move dont_repeat to here.
1499 * utils.c (error): Call wrap_here to force buffered output.
1501 Small patches from Peter Schauer:
1503 * coffread.c (start_symtab): Free any existing line_vector before
1505 (read_coff_symtab): Ditto for type_vector.
1507 * source.c (lines_to_list): New variable, replacing function.
1508 (all uses): Use as variable.
1509 (_initialize_source): Add 'set listsize' and 'show listsize'.
1510 * utils.c (lines_to_list): Remove function.
1511 * stack.c (print_frame_info): Use as variable.
1512 * defs.h (lines_to_list): Remove declaration.
1514 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1516 * breakpoint.c (insert_breakpoints): Restore warning about
1517 the program might be running in another process, but only for
1518 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1519 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1521 * utils.c (error): if error_pre_print is set, print the string
1523 * main.c (main, print_gnu_advertisement, print_gdb_version):
1524 Reformat legalese so it always prints, but acts as an "I'm here"
1525 message while symbols are being read. If any errors occur,
1526 print a few newlines to set off the message and start it at the
1527 left margin. Remove mention of "help" command, and don't yak
1528 about symbol reading.
1529 (catch_errors): Error string is now printed first in case of
1531 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1532 suggest the "help" command.
1534 * Makefile.in (VERSION): Set to 4.0.2.
1536 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1538 * .gdbinit: Remove useless "rr" command. Set complaints
1539 to 1 for people debugging gdb.
1541 * breakpoint.c, remote-vx.c: Reword strings printed by
1542 catch_errors callers.
1544 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1546 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1547 (Fix from kenc@viewlogic.com.)
1549 Fix some infrastructure to be able to cope with host and target
1550 machines with different sized basic types (ints, ptrs, etc).
1551 (Idea from pierre@la.tce.com (Pierre Willard).)
1553 * values.c (value_from_longest): Rename from value_from_long.
1554 Handle pointer types as well as integers, so that targets with
1555 different pointer sizes from the host can be accomodated.
1556 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1557 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1558 uses of value_from_long to value_from_longest.
1559 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1560 the correct pointer type to value_from_long{est}.
1562 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1564 * remote-vx.c: Remove obsolete code for calling functions via
1565 vxworks kludge interface (it referenced value_from_long).
1567 * valops.c (value_string): Find malloc with lookup_misc_func, not
1570 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1572 Make writing to files work properly. (Fixes to BFD are also needed.)
1574 * core.c (core_open): Open file ourselves, read or r/w, depending on
1575 write_files. Use bfd_fdopenr.
1576 * gdbcore.h (write_files): New variable.
1577 * exec.c (write_files): Define variable, add set&show for it.
1578 (exec_file_command): Use write_files to open for read or r/write.
1580 Make shared library reading happen automatically. These changes
1581 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1583 * inferior.h (stop_soon_quietly): Add to exported variables.
1584 * infrun.c (child_create_inferior): call solib hook, if defined.
1585 (child_attach): call solib hook, if defined.
1586 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1587 (find_solib): Use lookup_misc_func rather than hand-rolled.
1588 (symbol_add_stub): New stub for catch_errors.
1589 (solib_add): Avoid output if !from_tty. Catch errors rather
1590 than just calling symbol_file_add and bombing.
1591 (solib_create_inferior_hook): Interface with the target process
1592 to let it read and alloc shared libs, then figure out what it did.
1594 * core.c (validate_files): Fix typo, soften warning.
1595 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1597 * utils.c (fputs_demangled): Avoid duplicate printing if
1598 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1600 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1601 (Fix from pierre@la.tce.com (Pierre Willard).)
1603 * main.c (catch_errors): Change argument to a char * from an int,
1604 since a char * can point to a struct full of glop, but an int
1605 is not guaranteed to be able to hold a pointer.
1606 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1607 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1608 * core.c (core_open, solib_add_stub): Adapt.
1609 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1611 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1613 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1614 by adding .NOEXPORT target.
1616 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1620 * Makefile.in (VERSION): Roll to 4.0.
1621 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1623 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1625 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1628 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1631 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1633 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1634 reflect above name change
1636 * WHATS.NEW: correct pointer to refcard.
1638 * doc/gdb.texinfo: update New Features, Installing
1640 * doc/gdbint.texinfo: add short description of configure +template
1642 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1644 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1646 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1648 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1649 tar file, add dependencies for referenced doc files.
1651 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1653 * coffread.c, symfile.c, stack.c: saberized.
1655 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1657 * doc/refcard.tex: permuted Essential Commands sec
1659 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1661 set/show symbol-reloading
1662 default set complaints 0
1664 RET-repeat disabled after prompted long displays
1665 processID (attach) interpretation of 2nd GDB cmdline arg
1667 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1669 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1670 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1671 breakpoint.c, main.c: lint.
1673 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1675 Install new configuration scheme for GDB and friends.
1677 * config.sub: Translate ordinary names to three-part names.
1678 * configure: Use three-part names internally.
1679 * configure.in: Translate three-part names to filenames.
1681 * README, WHATS.NEW: Update for gdb-4.0.
1682 * Makefile.in: Roll VERSION to 3.99.
1684 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1686 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1687 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1688 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1689 to single structures rather than arrays; when passing
1690 their address, use &. This avoids trouble with bdead compilers.
1691 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1692 instead. This avoids portability headaches.
1693 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1695 * source.c (open_source_file): Avoid ANSI const bdeath by
1696 skipping declaration and then casting result value.
1697 * tm-hp300bsd.h: Clarify comment.
1698 * utils.c (strstr): Result is const char *; ANSI bdeath.
1699 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1700 since system include file defines it differently from "defs.h",
1701 though the two are equivalent for our purposes.
1702 * tconfig/hp300bsd: Add m68k-tdep.o.
1704 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1706 * tconfig/sun*4: Remove warnings about system assembler.
1708 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1710 * mcheck.c: Avoid warning about undeclared abort fn.
1711 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1712 it causes recursive calls to error() when used in cleanups.
1713 To do so requires that we make it a function, so we do.
1714 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1715 * utils.c (do_cleanups): Remove the current cleanup from the
1716 chain *before* calling it, in case error() is called from it.
1717 The result won't be pretty, but won't be an infinite loop either.
1719 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1721 * dbxread.c (read_struct_type): Grok anon structs for C++.
1722 (vb_name, vptr_name): Null terminate these strings.
1724 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1726 Minor bug fixes from BSD Net2 gdb:
1728 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1729 returns 0, there is no previous frame.
1730 * breakpoint.c (commands_command): If !from_tty, don't call
1731 input_from_terminal_p().
1732 * dbxread.c (record_misc_function): Speed up slightly.
1733 (compare_psymbols): Ditto.
1734 * infcmd.c (do_registers_info): Take a second argument to
1735 determine whether to print float registers. "info registers"
1736 does not do so anymore. "info all-registers" does, now.
1737 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1739 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1740 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1744 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1745 executing_breakpoint_commands if we are interrupted by error.
1746 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1747 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1748 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1749 catch_errors() so we can setup the frame regardless of whether
1750 the shared libs work.
1751 * ieee-float.c (double_to_ieee_extended): Get exponent from
1752 right place in little-endian systems. From John Carey.
1754 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1756 * main.c: Remove unused terminating_signals and catch_termination().
1757 (long_options): Terminate with a zero element.
1758 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1759 (gdb_readline): Make call-compatible with readline.
1760 (init_signals): Improve comments re vfork vs. signal.
1762 * utils.c (prompt_for_continue): Use new gdb_readline().
1763 If we prompt for continuation, we don't let CR repeat the previous
1764 command, once we get back to a prompt. It's too easy to keep
1765 hitting CR, expecting "--more--" prompts, and have some long
1766 command start repeating on you.
1768 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1770 * blockframe.c (frameless_look_for_prologue): Speed up by
1771 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1772 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1773 Define two variants, one faster.
1774 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1775 and return zero, rather than giving an error.
1776 (setup_arbitrary_frame): Initialize the PC in the new frame.
1777 (skip_prologue): Add a second arg saying whether we're just
1778 checking for a frameless function or not.
1780 * core.c (core_open, core_close, core_xfer_memory): Move
1781 section table pointers and bfd* into the target_ops.
1782 (core_open): Allow errors in shared lib reading, etc.
1783 (core_files_info): Describe shared library sections.
1785 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1786 exec_files_info, set_section_command): Move section table
1787 pointers and bfd* into the target_ops.
1788 (add_to_section_table): Add BFD to section table.
1790 * target.c (target_xfer_memory, target_info): Pass target to
1791 xfer_memory and target_info functions.
1794 * gdbcore.h: Move struct section_table.
1795 * target.h: New home of struct section_table.
1797 * solib.c (solib_add): New argument is the target_ops whose
1798 section list is to be added to, if any. Reallocate the
1799 sections in that target to add any that come from shared libs.
1800 (throughout) so_sections renamed to sections.
1801 (solib_xfer_memory): Deleted.
1802 * tm-sunos.h (SOLIB_ADD): Add target argument.
1803 (SOLIB_XFER_MEMORY): Delete.
1805 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1806 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1807 from target_ops. It's the same on all targets. Add two section
1808 pointers to target_ops.
1810 * stack.c (find_relative_frame): Dump ancient algorithm for
1811 "down", just use handy "next" pointers.
1812 (frame_command): Don't error if there is no stack; let user
1815 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1816 modifies static state in the parent process; new_tty itself
1817 runs in the child and modifies the child's file descriptors
1818 to match the saved static state.
1819 * infrun.c (child_create_inferior): Call new_tty_prefork,
1822 * infptrace.c (child_xfer_memory): Add ignored target arg.
1823 * remote-eb.c (eb_xfer_inferior_memory): ''
1824 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1825 * remote-vx.c (vx_xfer_memory): ''
1826 * remote.c (remote_xfer_memory): ''. Rename from
1827 remote_xfer_inferior_memory.
1829 * main.c (main): Only try to attach "corefile" argument if
1830 it starts with a digit.
1832 * symfile.c (symbol_reloading): New "set/show" variable.
1833 (symbol_file_add): Shorten message about symbol reading.
1834 (add_symbol_file_command): Merge with add_syms_addr_command,
1835 since this should work on all targets now.
1836 (stop_whining): Default to zero, to shut up complaints
1837 about bad symbol tables on many systems.
1838 (free_named_symtabs): Just exit unless symbol_reloading.
1840 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1841 and add comment explaining shared library screw.
1843 * source.c: #if defined => #ifdef.
1845 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1847 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1849 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1851 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1852 (doc/Makefile knows how to make one for local config)
1854 * Makefile.in: use doc/Makefile for doc targets
1856 * doc/Makefile: GDB documentation now has its own Makefile
1857 doc/refcard.tex: renamed from "gdbrc.tex"
1858 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1859 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1862 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1864 * values.c (baseclass_addr): When reading target memory, use the
1865 length of the basetype, not the upper type. We've only malloc'd
1866 enough space for the basetype, leading to errors in free().
1868 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1869 ends up as a function specially, since we know the actual type of
1870 the pointed-to address. This (somewhat) fixes display of
1871 expressions that include misc_function_vector names. Try `cond 1
1872 !strcmp("a","b")' then `i b'.
1874 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1875 The child can be proceeded from inside wait_for_inferior in
1876 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1877 getting skipped in that case.
1879 * expprint.c (print_subexp): Use filtered output, since the
1880 subroutines we call use it, otherwise the output is horribly
1881 mangled, since output of wrappable stuff comes out late.
1883 * Makefile.in: Bump VERSION to 3.98.1
1885 * infrun.c (child_create_process): Use execlp to find the
1886 shell to exec our target program. This requires some fiddling
1887 with `environ' since there is no execlpe().
1889 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1891 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1892 Minor rearrangement of refcard permits two new make targets--
1893 gdbrc.dvi DVI output for refcard, using CM fonts
1894 gdbrc.ps PostScript refcard, using PS fonts
1896 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1900 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1901 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1903 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1905 * doc/gdb.texinfo: last changes for release.
1906 Minor typo and formatting fixes; incorporated most fixes remaining from
1907 filed mail commenting on earlier drafts.
1909 Added warnings: pipes don't work in run command;
1910 conditions are converse of assertions;
1911 step over fn without debug info goes to next fn;
1912 vars may have "wrong" values near fn entrance, exit
1914 Added example from Kingston on printing repeated nonadjacent values
1916 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1917 shell mode for signals
1919 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1920 doesn't sound so much like its parent "Stopping and Continuing"; also
1921 moved entries on continue to top of section, so they don't get lost.
1923 Improved installation directions in appendix, added manual formatting
1926 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1928 * configure.in: Remove xm.h and tm.h even if we aren't linking
1929 new ones, so "./configure sun4; ./configure none" does the right
1930 thing. Assume that alldeps.mak and depend are already built in
1931 srcdir, and avoid running "make" (particularly "make depend",
1932 which involves "gcc") from inside configure. Build Makefile
1933 directly rather than building Makefile.conf first.
1934 * configure: Regenerate with above changes.
1935 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1936 to 3.98. Revise gdb.tar.Z procedure to produce a file
1937 called gdb-$(VERSION).tar.Z but which unpacks into a
1938 directory called "gdb". Move non-source files out of
1939 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1940 (depend): Don't try to do "gcc expread.y".
1941 (expread.o): Update dependencies by hand.
1943 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1946 Fixed a variety of small typos that prevented info from formatting
1947 cleanly; altered too-long heading for GPL Appendix, as discussed
1948 w/RMS; Changed date on cover to July 91.
1950 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1953 (1) Applied some fixes due to comments from Larry Breed (easier ones
1954 through chapsec 5.2)
1955 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1956 it's broken in latest texinfo
1957 (3) Introduced *some* use of [] for optional arguments, where
1958 explanation is not simpler by listing cmd w arg and cmd w/out arg
1959 separately. Still not using @deffn.
1960 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1961 couple of headings are too long. Need patches to texinfo or revision
1964 * Partial update to README (which still needs work for this
1965 release!): (1) use of configure corrected for new script,
1966 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1968 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1970 * symtab.c (lookup_symbol): Don't complain right off about
1971 no debug symbols; use the misc function vector first.
1972 (list_symbols): Use misc function vector to find symbols
1973 that don't have debug info, and print them.
1974 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1975 PC range doesn't match symtab PC range, as it does on the
1976 MIPS because our symtab reading isn't perfect.
1978 * dbxread.c (dbx_symfile_read): Make warning about
1979 "no debug symbols" slightly nicer.
1981 * source.c (select_source_symtab): If "main" symbol exists,
1982 but decode_line_spec can't find line info, don't just return
1983 a zero; try other source symtabs or give an error.
1985 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1986 their low addresses first, then rip through fixing high addrs.
1988 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1989 <runene@ifi.uio.no>.
1990 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1992 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1994 * Minor, mostly mechanical, cleanup of doc subdir for clean
1995 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1996 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1998 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
2000 Mostly MIPS and general symbol-reading fixups.
2002 * doc/gdbint.texinfo: Add documentation on symbol-reading
2005 * mipsread.c: Remove kludges around #include "ecoff.h".
2006 Remove redefinitions of a_magic, etc, no longer used.
2007 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
2008 Fix global overview comments to match symfile.c protocol.
2009 (mipscoff_new_init): Eliminate cur_hdr if we have one.
2010 (mipscoff_symfile_read): Eliminate unused code. Avoid
2011 sorting all the symtabs, when all we have read here is psymtabs.
2012 The symtabs are sorted as they are created anyway. Tell
2013 condense_misc_bunches whether we're mainline.
2014 (psymtab_to_symtab_1): Pass filename when recursing, to make
2015 stack trace more informative.
2016 (parse_partial_symbols): Assume cur_hdr as argument.
2017 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
2018 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
2019 the TYPE_NAME of char *, since that's done in symfile.c.
2020 (free_numargs, parse_symbol, add_symbol, add_block,
2021 shrink_linetable): Declare these fns void.
2022 (upgrade_type): Convert tree of if's to switch. Clean up
2023 bogus "off == 0" handling with a complaint. Avoid setting
2024 field bitpos and bitsize of array with lower and upper bounds.
2025 Check specified bitsize of elements against their actual type's
2026 bitsize, and complain if different. Complain about unknown
2028 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
2029 (psymtab_to_symtab_1): Print names of subsidiary files that
2030 are being read in. FIXME, we read far too many files. This code
2031 is not the problem, the problem is in parse_fdr where the psymtabs
2033 (cross_ref): Result should indicate that we used one aux entry
2034 normally, or two if we encountered a "next" entry. This used
2035 to leave the caller pointing at the wrong aux entry.
2036 (add_symbol): If overflowed cur_block, reallocate it larger,
2037 chase all pointers to it, and complain(), rather than clobber memory.
2038 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
2039 (new_field): Only allocate one field initially, not two.
2040 Pull ++ out of macro argument. Simplify.
2041 (_initialize_mipsread): Avoid initialization of importd
2042 global_psymbols and static_psymbols.
2044 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
2045 to properly set pst->symtab; avoid searching for it.
2046 (symfile_fns): Improve comments, add a FIXME.
2047 * dbxread.c: Update comments to reflect symfile protocol.
2048 (read_ofile_symtab, end_symtab): Return the symtab.
2049 (psymtab_to_symtab_1): Set pst->symtab.
2051 * coffread.c (coff_symfile_read): tell condense_misc_bunches
2052 whether we're mainline.
2054 * symfile.h (sym_fns): Remove unused sym_discard member.
2055 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
2057 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
2058 the environment variable is not.
2059 * infcmd.c (finish_command): Use filtered printfs.
2060 * cplus-dem.c: Add struct tags to a few unnamed structs.
2061 * valops.c (value_coerce_array): Improve comments.
2062 * valprint.c (type_print_varspec_suffix): Print array size only
2063 if greater than zero.
2064 * m88k-tdep.c: Shift some lines left by one space, that had
2065 apparently been trashed at some point.
2066 * TODO: More things to do, a few got done.
2068 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2070 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
2071 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
2073 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
2074 * expread.y, findvar.c, symmisc.c: Ditto.
2075 * printcmd.c (address_info): Update printed forms of LOC_
2076 symbols. Elim LOC_EXTERNAL.
2077 (print_frame_args): Keep track of param stack offsets before
2078 re-looking up to find the local register param is kept in.
2080 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
2081 Further integration of mipsread into gdb. Eliminate unused
2082 routines, duplicate declarations. Handle static symbols in
2083 psymtabs as well as external symbols. When reading symtabs,
2084 insert symbols into the correct block (global, static, or a local
2086 (read_mips_symtab, parse_partial_symbols): Don't pass useless
2088 (mipscoff_symfile_read): Don't call select_source_symtab.
2089 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
2090 rather than SYMBOL_VALUE.
2091 (parse_external): Comment clobbering of top_stack.
2092 (parse_partial_symbols): Update comments. Allocate and parse
2093 static symbols as well as external symbols. FIXME, enum values
2094 are not handled in this pass, but should be. Inline new_psymbol.
2095 Use SYMBOL_VALUE_ADDRESS.
2096 (psymtab_to_symtab_1): Read symbols into global static block
2097 by default (until enter some function's local block context).
2098 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
2099 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
2101 * source.c (select_source_symtab): Select a source symtab
2102 from either the symtabs or, failing that, the psymtabs.
2103 (list_command): Update error message.
2104 (forward_search_command, reverse_search_command): Use getc, not
2105 fgetc, for speed. FIXME, add comment about buffers that die if
2106 overrun by long line.
2108 * values.c (unpack_field_as_long, modify_field): Avoid shifting
2109 by an entire word, which is not portable, if we have a 32-bit
2110 field. (Code in dbxread.c already turns such bitfields, if
2111 aligned, into ordinary ints, but fixing this will help for other
2112 symbol formats and for future changes.)
2113 * core.c (core_open): Handle ANSI const brain death.
2114 * utils.c (vprintf): Fix varargs typo.
2116 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2118 * findvar.c (find_var_value): Handle &function better.
2119 * TODO: Document work needed on &fn and &array.
2120 * printcmd.c (print_address_symbolic): New arg is the prefix
2121 to print if a name is printed.
2122 (print_address_demangle): Honor "set print address" now.
2123 Use new arg above to improve spacing of output.
2124 * valprint.c (val_print): When printing function pointers,
2125 print symbolic form too.
2126 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
2128 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2130 * core.c (memory_error): Reword error msg to mislead less.
2132 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
2134 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
2135 parse_partial_symbols): Use newer BFD internals (external_filehdr
2136 and external_aouthdr), byte-swap the fields that we care about
2137 before using them, and make the file header data local to
2138 read_the_mips_symtab rather than global.
2140 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
2142 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
2143 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
2145 * main.c (command_line_input): Flush stdout and stderr
2146 before every call to readline. This reportedly fixes a bug
2147 that comes up in Sys V running emacs-gdb and/or xxgdb,
2148 when stdin/out are pipes or sockets.
2150 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2152 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
2153 Avoid declaring Makefile dependencies, because GNU Make stupidly
2154 tries to update it if we do.
2156 * coffread.c: Revise for minor changes to bfd internal coff
2159 * configure: If -template= is given a relative path, make it
2160 absolute before recurring in subdirectories.
2162 * configure, configure.in, Makefile.in: Install "configure" script
2163 as replacement for config.gdb.
2164 * config.gdb, Makefile.dist, Makefile.sdir: Remove
2165 * README: Update for configure, mostly. FIXME.
2167 * Add dec3100 as equivalent to littlemips. Indicate in all host &
2168 target config files that they are for the host. When the lines
2169 get copied into the Makefile, this makes it more obvious what's
2172 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2174 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
2175 tabs, which end up in the disassembler output inadvertently.
2177 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2179 Make it compile cleanly in an ANSI GCC2 environment.
2181 * blockframe.c: <stdio.h>
2182 * cplus-dem.c: free takes a void *, ifdef __STDC__
2183 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
2185 * defs.h (alloca): Avoid doing anything if alloca already def'd.
2186 * stddef.h, stdlib.h: Remove these files.
2187 * symtab.c: Avoid declaring qsort, close.
2188 * symfile.c: Avoid declaring close.
2189 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
2190 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
2192 Assorted other changes.
2193 * dbxread.c: include "libaout.h", not "liba.out.h".
2194 * printcmd.c (print_frame_args): Set recurse properly for
2195 indentation of struct and array parameters.
2196 * valops.c (value_cast): Allow cast to void.
2197 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2198 single_step() in a target-independent fashion.
2199 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2200 set up to be ready to continue. This makes us target independent.
2201 * infptrace.c (child_resume): Remove call to single_step; now
2202 can single step a SPARC target of any kind.
2204 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2206 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2207 docn into separate sections---basically chapters, plus two loose
2208 pieces that can be configured to go in different places. This
2209 allows GNU m4 to preprocess the manual without coredumping.
2211 * Makefile.dist: tell TeX where to find texinfo.
2213 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2215 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2216 the new target "rdl-apps.texinfo" which captures the Makefile
2217 variable that records where to find the Readline libraries.
2219 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2221 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
2222 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
2223 * defs.h (const, volatile): Only define if not already defined.
2224 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2226 * README: Update for release 3.95.
2227 * config.gdb: Don't create readline dir in subdir builds.
2228 * main.c: Include with "..." form for non-system include files,
2229 so "gcc -MM" for "make depend" works.
2230 Include readline files with "...h" rather than <readline/...h>.
2231 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2233 * coffread.c: Undo minor damage done by Rich Pixley. Use
2234 different internal and external representations of COFF
2235 data structures. Use new BFD routines for swapping them in and
2237 * symfile.c (free_named_symtabs): Avoid freeing file names that
2238 are null or empty. Old i960 tools seem to produce files that
2239 claim to have empty names, causing each successive file read
2240 to blow away the previous one.
2241 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2242 Move deferred_stores to top of file, but don't separate its
2243 #define's from its variable. Add commentary.
2244 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2245 favor of keeping the (working) config.gdb. Move readline
2248 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2250 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2252 * infptrace.c (fetch_registers): no result, since now void.
2253 * tconfig/news: target depends on m68k-tdep too.
2255 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2257 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2260 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2261 applied various small fixes due to or inspired by RMS comments
2263 * doc/gdb.texinfo: finished using all RMS comments, save those for
2264 appendices on readline and cmd history (which are in other source
2267 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2269 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2270 chapter 9; (2) documented 'break' command's menu mode for
2271 overloaded names, in response to hgs problem report C++ p-31
2273 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2275 * doc/gdb.texinfo: (1) better introductory example; (2) more
2276 consistent use of @code, @samp, @file, @kbd throughout; small
2277 cleanups to first three nodes; (3) new "Contributors" node;
2278 (4) Appendix, Renamed Commands; (5) divert specialized startup
2279 instructions to "Targets" chapter for generic manuals, while
2280 leaving them up front for manuals specific to specialized
2281 environments; (6) apply fixes from RMS comments through chapter 4.
2283 * pretex.m4: modify explanatory text slightly (and redefine
2284 "regexp") to keep GNU m4 from complaining. (It still crashes
2285 later, but one step at a time...)
2287 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2289 * readline/readline.c (update_line): Avoid dereferencing a pointer
2290 before comparing it to its bounds. Saber caught this.
2291 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2292 and only set PC if tgetstr returned non-null. Saber caught this.
2294 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2296 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2297 stuff for config manual) here where it counts; updated
2298 to use new subdir structure (gdb/doc/).
2300 * Makefile: generated from above via
2304 * gdbint.texinfo: added instructions on generating gdb.info* files
2305 locally for release. These are ordinary info
2306 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2307 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2308 to generate these, so we distribute them already formatted.
2310 * gdb.texinfo: included full Info node and menu crud (as generated
2311 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2313 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2314 put in comments-for-future gdb.info target (one day makeinfo will
2317 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2319 * gdb.texinfo: Updated to include new or old undocumented
2320 commands, at least the following (perhaps some others I forgot to
2321 record): info f, info float, info path, info program, info s, info
2322 set, info source, info terminal, info types, info user, set/show
2324 Also covered all recent GDB command renames for v4.
2326 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2328 * mipsread.c: Rather than keeping count of how many symtabs
2329 and psymtabs we have, for sorting purposes, count them when
2330 we need to sort. This fixes bug in rereading of symbol tables.
2332 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2334 * infcmd.c: renamed "info path" to "show paths"
2335 * gdbrc.tex: documented above.
2337 Wed May 8 04:51:11 1991 John Gilmore (gnu at cygint.cygnus.com)
2339 * remote.c: Fix comments.
2340 * utils.c (error): Force out any pending wrap output.
2342 Sat May 4 11:11:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2344 * Makefile.dist: Roll VERSION to 3.95.
2345 Fix up "saber_gdb" to work again.
2346 * saber.suppress: Update.
2348 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
2349 symtab.h, target.c, target.h: Lint.
2350 * core.c: setup and select frame after reading shared libs,
2351 else reading shared libs will clobber them. Lint.
2352 * utils.c (error): Force out any buffered wrap text.
2354 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2356 * remote.c: Remove decls of memory_insert_breakpoint
2357 and memory_remove_breakpoint, no longer used. (Suggestion of
2360 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2361 to make it easier to interface to "configure"'d libraries.
2363 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2365 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
2366 aliases for set/show print.
2368 Thu May 2 11:22:02 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

2389 * m88k-pinsn.c (sprint_address): Declare at top of file.
2391 * m88k-xdep.c: #if 0 out core_file_command.
2393 * values.c ({unpack_,value_as_}pointer): Just call
2394 {unpack_,value_as_}long (for now anyway).
2396 * m88k-tdep.c (get_saved_register): Make get_reg a dc_word_t (*)().
2397 (psr_register): Change return type to dc_word_t.
2399 * m88k-tdep.c (tdesc_read_function): Comment out call to ptrace.
2401 * m88k-tdep.c (get_saved_register): Add lvalp parameter.
2403 * gdbcore.h (write_memory): Don't prototype it.
2405 * tm-88k.h, m88k-tdep.c: Make stack_error, stack_jmp global.
2406 m88k-xdep.c: Don't mention stack_error.
2408 * {x,t}config/m88k ({X,T}DEPFILES): Add missing files.
2410 * mtrace.c: Don't typedef things like size_t, just #define them.
2412 * coffread.c [TDESC]: #if 0 out references to coffsyn.
2414 * symtab.h (struct symtab): Include EXTRA_SYMTAB_INFO.
2415 tm-88k.h: Define EXTRA_SYMTAB_INFO.
2417 * coffread.c [TDESC]: Include "tdesc.h" and make tdesc_handle
2418 dc_dcontext_t not int.
2420 * coffread.c [TDESC]: Use system include files not <intel-coff.h>.
2422 * coffread.c [TDESC]: Move setting of debug_info from
2423 coff_symfile_read to find_linenos and make it work with BFD.
2425 * cplus-dem.c [__STDC__]: Make x{m,re}alloc return void*.
2427 * signame.c: Cast const char* to char* when assigning to sys_siglist.
2429 * utils.c (strsave): Make arg const char* not char*.
2431 * infrun.c (wait_for_inferior) [SHIFT_INSN_REGS]: Use
2432 bpstat_explains_signal (stop_bpstat) not stop_breakpoint.

2901 * symfile.h (free_named_symtabs): Rename from free_named_symtab.
2902 * symfile.c (clear_symtab_users_once, cashier_psymtab,
2903 free_named_symtabs): Move these routines from symmisc.c.
2904 * symmisc.c (same): same.
2905 (free_symtab): Make non-static.
2906 * symtab.h (free_symtab): Declare as exported void fn now.
2907 * dbxread.c (end_symtab, end_psymtab): Change comments.
2908 (initialize_dbxread): Call dbx_new_init() in case the first
2909 command is add-symbols.
2910 * target.c (dummy_target): Permit add_syms_addr_command.
2912 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2914 Permit symbols to be superseded when new symbol files have
2915 been read in, particularly for VxWorks.
2917 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
2918 to the main file, as well as to include files. Also, put global
2919 functions into the global psymtab, to make "i fun" work.
2920 (end_psymtab): Free named symtabs and psymtabs for a file, once a
2921 new psymtab for it has been read.
2922 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
2923 a file, once a new symtab has been read for it.
2924 * mipsread.c: FIXME. We need to do the same for MIPS, but it
2925 looks harder to determine the top-level block before it's been
2926 queued to the psymtab list.
2928 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
2929 If we have wiped out any old symbol tables, clean up at end of
2931 (symbol_file_command): Don't reference symfile_fns if it's zero.
2933 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
2934 defines for the blocks of a blockvector that contain global and
2935 file-static symbols and the first of the smaller scope contours.
2936 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
2937 decode_line_1, make_symbol_completion_list): Use the above.
2938 * coffread.c (end_symtab, patch_opaque_types): Ditto.
2939 * dbxread.c (end_symtab): Ditto.
2940 * expread.y (block): Ditto.
2941 * mipsread.c (throughout): Ditto.
2942 * symmisc.c (free_named_symtabs): Ditto.
2944 * symtab.c (list_symbols): Process the first symbol of the
2945 static psymbols list.
2946 (types_info): Restore this function from its untimely #if 0.
2947 It's not perfect, but it is better than nothing.
2948 (_initialize_symtab): Restore "info types".
2950 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2952 * m68k-stub.c: Remote stub for 680x0's, created from
2953 rem-m68k.shar (which is removed).
2954 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
2955 Remove RCS log stuff now that we use CVS and it blows our diffs.
2957 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2959 * symmisc.c (free_named_symtab): Make it work, in its current
2960 kludgy fashion. Change result to indicate if we blew away bkpts.
2961 * dbxread.c (end_symtab): Accumulate result from
2962 free_named_symtab and print warning if we blew user's state.
2963 * symfile.h: free_named_symtab now returns an int.
2965 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
2967 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
2968 is the first symbol read, even if not mainline.
2969 (dbx_psymtab_to_symtab): symfile might be zero, cope.
2970 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
2971 (set_section_command): New command ("section xxx yyy" -- should
2972 be renamed to "set section xxx yyy" FIXME) which sets the
2973 base address of a section of the exec file, overriding the
2974 virtual address that BFD reports.
2976 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2978 * exec.c: Add add_syms_addr_command to exec_ops, so you can
2979 load symbols at any address while examining an exec file.
2981 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2983 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
2984 for printing the float info is host-dependent, not
2985 target-dependent. FIXME.
2986 * i386-pinsn.c: Move #includes to top, remove useless ones.
2987 * i386-tdep.c: Don't bother including <.../reg.h> since we
2988 don't use it (and it doesn't exist on host systems).
2990 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
2991 Convert negative numbers properly.
2992 (ieee_test): Make numbers really random; fix format arg.
2994 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
2995 * core.c (core_detach): Unpush core_ops, which might not be on
2996 top. We used to just pop the top, which broke things. Don't
2997 need dont_repeat() any more.
2998 (core_file_command): Psst! Don't repeat it.
2999 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
3000 * expprint.c (print_subexp): Avoid switch fallthru on
3001 BINOP_ASSIGN_MODIFY, so we can print += and such.
3002 * frame.h: Fix typo.
3003 * inflow.c (kill_command): After killing inferior, print our
3004 current frame in the core file, if we have one.
3005 (generic_mourn_inferior): When inferior dies, either select
3006 the current frame (in the new target, e.g. core file), or
3007 set both the current and selected frames to NULL.
3009 Changes from Peter Schauer.
3011 * infptrace.c: Avoid <sys/ptrace.h> on USG.
3013 * Make all file names fit in 14 characters (sigh and damn!):
3014 mv hp300hpux-xdep.c hp300ux-xdep.c
3015 mv symmetry-xdep.c symm-xdep.c
3016 mv symmetry-tdep.c symm-tdep.c
3017 mv convex-opcode.h convx-opcode.h
3018 mv tm-vxworks960.h tm-vx960.h
3019 mv tm-vxworks68.h tm-vx68.h
3020 mv Makefile.srcdir Makefile.sdir
3021 mv gdb-int.texinfo gdbint.texinfo
3022 mv remote-sa.m68k.shar rem-m68k.shar
3023 mv remote-multi.shar rem-multi.shar
3024 * Makefile.dist, README, config.gdb, convex-pinsn.c,
3025 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
3026 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
3029 * command.c (user_info_1, user_info): New command for listing
3030 the user-defined commands.
3032 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
3034 * dbxread.c (really_free_pendings): Clear file_symbols
3035 and global_symbols after freeing them; otherwise, running
3036 this function twice (if it appears twice on the cleanup
3037 chain), we try to free things twice.
3039 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
3040 based on text_addr (the address of text in core), not on addr (the
3041 offset between text in the .o file and in core). This change
3042 is from Peter Schauer.
3044 * main.c: Define ALL_CLEANUPS as a cast of zero.
3045 (return_to_top_level): Use it.
3046 (main): Do all cleanups after each command run as part
3047 of the gdb startup sequence. Also do all cleanups before
3048 entering the command loop, and every time we exit the command
3049 loop and reenter. Before, the cleanups from the startup sequence
3050 were being left undone until the first error!
3051 (command_loop): Rename do_nothing cleanup to command_loop_marker
3052 so we can see it easily when examining the cleanup chain.
3053 (init_signals): Add another do_nothing for signal handling.
3054 (quit_command): Only try to kill target if it has execution.
3055 Problems in the target stack got us into a state where
3056 inferior_pid was nonzero but none of the targets had execution.
3057 In this state you couldn't exit gdb.
3059 * dbxread.c: Two changes from Peter Schauer.
3060 (echo_command): Fflush output after an echo command.
3061 (show_history): Pass all args to cmd_show_list.
3063 * utils.c (init_malloc): Call mtrace to turn on tracing
3064 if the environment variable MALLOC_TRACE is set to a file name.
3065 * mtrace.c: Add source file which provides a log of every malloc,
3066 free, and realloc to a trace file.
3067 * mtrace.awk: Add source file which analyzes the trace file.
3068 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
3069 (VERSION): Roll to 3.94.3.
3071 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
3072 (check_duplicates): Don't bother with watchpoints.
3073 (set_raw_breakpoint): Comment about danger of this routine.
3074 (watch_command): Parse and eval all args before calling
3077 * solib.c (find_solib): Avoid error in referencing memory to
3078 see if any more shared libraries have been added. This is
3079 particularly useful if the target has terminated. Bug reported
3082 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
3083 in bringing up 3.94.2 on the Sun-3.
3085 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
3086 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
3087 expression (in scope) before reenabling watchpoint.
3088 * signame.c (init_sigs): Add missing declaration of i, fix
3089 sys_siglist declaration.
3090 * source.c (list_command): Fixed range computation to use
3092 * stack.c (backtrace_command): Do not allow command if target has
3093 no stack, print informative error message.
3094 * target.c (target_command): Do not write into command line
3095 because this fails if the target command is used in a user defined
3096 command. [This change was enhanced by gnu to support any-
3097 unique-prefix matching on target names.]
3098 * valops.c (value_struct_elt): Avoid infinite loop on an
3099 erroneous attempt to print the member of function (try p main.p).
3101 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3103 * expread.y (name_no_typename): Avoid reduce/reduce errors
3104 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
3105 Since the GDB parser really doesn't use name_no_typename in a
3106 name-only context, the parser can't tell the diff between
3107 names and numbers here. Avoid allowing a name_no_typename
3108 to be a NAME_OR_*INT to resolve the conflict.
3110 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3112 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
3114 * valprint.c (val_print_fields): bitfield printing didn't handle
3115 byte order. Indirect through a few more fns to cope.
3117 * values.c (modify_field): also cope with byte order.
3119 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
3121 Cleanup for release 3.94.2:
3123 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
3124 include files. Roll version to 3.94.2.
3126 * coffread.c (init_stringtab): Read length into unsigned char
3127 array before swapping; don't assume 32-bit longs.
3129 * target.c (target_info): Don't bother with get_sym_file, just use
3130 the symfile global variable.
3131 * symtab.h, symfile.c (get_sym_file): Delete it.
3133 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
3134 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
3135 (read_type): Replace one more error() with complain().
3137 * mipsread.c (parse_partial_symbols): Replace printf with complain.
3139 * i960-tdep.c: Fix copyright attribution.
3141 * config.gdb: Quote all backquotes in doublequotes. You can
3142 quote me on that. BSD 4.4 shell found this one.
3144 * infptrace.c (throughout): The third argument to ptrace is an
3147 * infrun.c (wait_for_inferior): When program has terminated, we
3148 have to call target_terminal_ours before we pop that target off
3149 the stack (e.g. before a call to target_kill or
3150 target_mourn_inferior). This fixes problem where a program
3151 terminates, then GDB stops for (tty output) and you have to type
3152 "fg" to the shell to resume it. FIXME: This code for what to
3153 do after termination really should be in normal_stop instead.
3155 * gdbcore.h (read_memory_check): Change declaration; it changed
3158 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
3159 4.4 prereleases, this avoids a bug in their sgtty compatability
3161 * remote.c: Use terminal.h rather than hand-rolling the same.
3163 * signame.c, signame.h (psignal): Arg is unsigned, not int.
3164 * utils.c (strsave, strstr): Fix arg types.
3165 * valprint.c (val_print): lint
3167 MIPS symbol table support from Per Bothner:
3169 * symfile.c (symtab_fns): Remove initializer table that needs to
3170 be hacked for each new symbol file format supported.
3171 (add_symtab_fns): New function, chains symbol table
3172 handlers into the global list.
3173 (symfile_init): Search this list.
3174 * symfile.h: Add next pointer, declare add_symtab_fns.
3175 * coffread.c (_initialize_coffread): Call add_symtab_fns.
3176 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
3178 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
3179 symbol *). Thus, we no longer need the hack to trash
3180 pst->filename. Good, since that hack confused code in symfile.c!
3182 (reorder_symtabs, destroy_all_symtabs): Removed static
3183 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
3184 Instead, the latter now uses a temporary array (stack-allocated
3185 from an obstack, and then freed).
3187 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
3188 haven't been set in the outermost stBlock of a procedure. This was
3189 a problem with f77 binaries on Ultrix 4.?.
3191 (new_symtab, new_symbol, new_type): Continue changing code to use
3192 obstacks more and otherwise conform to dbxread internal style.
3193 Made the free_code of symtabs be free_linetable (as in dbxread)
3194 instead of free_contents. This implies memory leaks when reading
3195 a new symbol table, until the conversion is finished. Did change
3196 (struct symbol) and (struct type) to be allocated on the
3197 symbol_obstack. Blocks and blockvectors are among the things
3200 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3201 tested much, but it solved one problem (reported by Meissner), and
3202 cleans up some other things. The problem happened when an
3203 included file contains actual code (functions) and not just
3204 definitions. The mips coff is a little inconvenient there, since
3205 it may cause a procedure to be mapped to the wrong psymtab.
3207 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3208 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3209 this will need work for the new core paradigm.
3211 Opcode patches from the net:
3213 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3214 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3215 missing altogether - they are added here. From Bruce Bauman.
3216 * mips-opcode.h: The low mask for C0 instructions was too small.
3217 From Garrett Lau. I modified the fix to check the entire 32-bit
3220 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3223 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3225 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3227 * dbxread.c (read_type): Pointer subtraction (value_sub in
3228 valarith.c) sometimes failed because the types of the
3229 pointers being subtracted were not identical.
3230 These differed because dbxread.c was allocating pointer types
3231 using dbx_alloc_type+smash_to_pointer_type instead of
3232 lookup_pointer_type. I failed to find a justification for the
3233 former, so I changed it to use the latter. Similarly, I
3234 replaced smash_to_function_type by lookup_function_type,
3235 and smash_to_reference_type by lookup_reference_type.
3237 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3238 _initialize_mipsread): corresponding changes.
3240 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3242 * source.c (mod_path): Do tilde_expand on each component of the path,
3243 rather than on the (list of) paths as a whole.
3244 (print_source_lines): Set first_line_listed in addition to
3245 current_source_symtab and current_source_line. If the source was
3246 not findable, after a "dir" command to fix the problem,
3247 a "list" would get the wrong lines.
3249 While I was there... (gnu):
3251 * dbxread.c (read_type): Change error to complaint.
3253 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3255 First attempt at detailed understanding of symbol table memory alloc.
3257 * dbxread.c (dbx_symfile_read): Free our string table if we
3258 aren't the mainline. Free the "info" struct since we're done with
3260 (init_psymbol_list): Free any previously allocated psymbol lists.
3261 (): FIXME: Should realloc-down the psymbol lists when done reading
3262 the main symbol file?
3264 * symmisc.c (free_symtab): Free fullname field too.
3266 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3267 (REGISTER_ADDR): Make result type unsigned int.
3269 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3270 define REGEX must also define REGEX1 (its dependency).
3272 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3274 * tconfig/i960: No longer works, points you at vxworks960 or
3277 * xgdb.c, XGDB-README: Remove file. Users can get the much
3279 * Makefile.dist: Remove all trace of xgdb.
3281 * breakpoint.c (breakpoint_1): Pass demangle arg to
3282 print_address_symbolic.
3283 (clear_breakpoints): Remove unused function.
3284 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3285 (breakpoint_re_set): Use catch_errors to do them all anyway.
3287 * gdb-int.texinfo (Host versus Target): Add section on what is
3288 a "host" feature versus what is a "target" feature.
3290 * infcmd.c (path_command, path_info): Handle the PATH variable
3291 (object search path) as conveniently as the source search path.
3292 * environ.c (set_in_environ): Set some vars in GDB's environment,
3293 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3294 * source.c (mod_path): New function, from guts of
3295 directory_command, modifies a path. Used by path_command.
3296 (directory_command): Call it.
3297 * defs.h (strsave): Declare.
3299 * utils.c (sevenbit_strings): Add new printing option.
3300 (printchar): Use it.
3301 (strsave): Provide this handy helper routine.
3302 (set_width_command): Rename set_screen_width_command.
3303 (_initialize_utils): "set screen-width" => "set width";
3304 "set screen-height" => "set height"; add sevenbit-strings.
3306 * infcmd.c (do_registers_info): Print floating point registers
3307 in raw hex as well as float format, regardless of whether it is
3308 a "virtual" convertible register.
3309 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3310 regs as a double, just in case it's being used that way.
3311 * values.c (unpack_long): Comment on array/function coercion.
3312 (unpack_double): Argument is in target byte order now. For
3313 integer arguments, just call unpack_long and float the result.
3314 * m68k-tdep.c: include defs.h for "const" handling.
3315 * remote-nindy.c: Use ieee-float stuff.
3316 (nindy_fetch_registers): Unpack double regs to host double, then
3318 (nindy_store_registers): Pack extendeds to host double, flip
3319 around by misusing unpack_double, send as target double.
3321 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3322 zero, as when stopped at the first instruction of a process.
3324 * blockframe.c: Fix filename in comment (param.h => tm.h).
3325 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3326 * tm-68k.h: Fix typos.
3328 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3330 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3332 * coredep.c (fetch_core_registers): Pass end-address of register
3333 section to register_addr as expected. Don't call supply_register
3334 if we'd just pass it garbage.
3336 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3338 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3340 * target.c (push_target, target_info): Cast enums to int for < or
3343 * stack.c (print_frame_info): Identify source file & line
3344 even if we can't print it.
3346 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3348 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3350 Clean up IEEE floating point support.
3352 * ieee-float.h: New file.
3353 * ieee-float.c: Write real routines to convert between host
3354 doubles and various target IEEE extendeds.
3355 * m68k-xdep.c: Eliminate assembler code for extended floats.
3356 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
3357 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3358 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3359 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3360 double_to_ieee_extended.
3361 * i960-tdep.c: Define ext_format_i960.
3362 * m68k-tdep.c: Define ext_format_68881.
3363 * sparc-tdep.c: Define ext_format_sparc, though unused.
3364 * Makefile.dist (HFILES): Add ieee-float.h.
3365 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3368 Obsolete the "coffstrip" program in favor of using BFD's strip.
3370 * nindy-share/coffstrip.c: Remove file.
3371 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3372 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3373 * tconfig/nindy960: Remove reference to coffstrip.o.
3375 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3377 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3379 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3380 * dbxread.c: Remove static symfile_bfd.
3381 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3383 * inftarg.c (child_detach): Pop the child_ops vector if the
3384 detach is successful.
3385 * remote-nindy.c (nindy_create_inferior): Don't push a new
3386 nindy_ops since nindy uses the same one for execution and memory
3388 * core.c (core_ops): Use child_attach and child_create_inferior
3389 rather than default attach and create_inferior functions.
3391 Handle floating point registers in core files.
3393 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3394 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3395 This version untested since BFD doesn't yet support sun3 core
3397 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3398 conventions. Fix comments and style. This version has not
3399 been compiled yet, since we have no HP inhouse.
3400 * core.c (get_core_registers): Look for two sections, ".reg"
3401 and ".reg2", and pass both to fetch_core_registers sequentially.
3403 Revise directory path yet again.
3405 * source.c (forget_cached_source_info): Not static any more.
3406 (init_source_path): New default source path is "$cdir:$cwd".
3407 (dir_command): Handle variable arguments ($cdir, $cwd).
3408 (source_info): Print "Compilation directory" rather than
3409 "Originally compiled in" to remind people of $cdir.
3410 (openp): If the path contains $cwd, use current directory.
3411 (open_source_file): If compilation directory is known, replace
3412 first $cdir in path with the compilation directory.
3413 (print_source_lines): Even if we can't print the lines, set the
3414 current symtab and line for future commands like "info source" or
3415 "breakpoint". Also, error message now contains the file name,
3416 line number, and file access error message.
3417 (_initialize_source): Fix help text to describe changes.
3418 * main.c (cd_command): Forget cached source info when we chdir.
3419 * utils.c (strstr): Add simple implementation.
3421 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3423 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3424 Byte-swap COFF symbol tables if necessary when reading them in.
3425 Use complain() to replace error message in one spot. Needs
3426 corresponding change in bfd/coff-code.h to make some symbol
3427 swapping routines non-static.
3429 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3431 Merge changes from Eirik Fuller, for UTek.
3433 * defs.h (errno): Add declaration.
3434 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
3435 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3436 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3437 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
3438 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
3439 declarations of errno.
3441 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3443 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3444 <rpc/rpc.h> and <rpc/types.h>.
3446 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3448 * i960-tdep.c (examine_prologue): Add new argument limit,
3449 which stops the scan at the end of the prologue, or at the PC.
3450 This fixes a problem where it walks down into the code for the
3451 user's statements if that code looks like function prologues.
3452 Mark Fox and I have been bouncing this code back and forth, making
3453 small changes to it. Callers changed to match.
3455 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3457 Cleanup for gdb-3.94 release final:
3459 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3460 the .c files from vx-share and nindy-share, from the various
3461 macros, since they are not found via ALLDEPFILES.
3462 (SFILES): Add tm-i960.h.
3463 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3464 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3466 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3467 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
3469 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
3471 * am29k-tdep.c: Add contribution line.
3472 (examine_prologue): Cache information about function prologues in
3473 the misc-function-vector to avoid lots of references over the
3474 serial line while examining instructions.
3476 * core.c (core_close): New function made from cleanup_core.
3478 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3479 remote-vx.c, remote.c, target.c, target.h,
3480 Update target_ops vector to add attach, close, and load entries.
3481 Use add_syms_addr_command, not add_file_addr_command, for
3482 add_file. Break out close routine from existing code.
3484 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3485 they are in an obstack.
3486 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3488 (define_symbol): Add symbol type parameter; change callers;
3489 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3490 it to influence the symbol class on the i960.
3491 (define_symbol): Swap LOC_CONST's into target byte order.
3493 * exec.c (exec_close): New function.
3494 (exec_file_command): Call it.
3496 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3497 Fix byte order of frame pointer.
3498 (read_var_value): Result of 0 if var's value can't be found,
3499 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3500 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3501 (locate_var_value): Use read_var_value and use its lazy address
3502 as the location of the var's value. Lint.
3504 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3507 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3508 obsolete Intel versions in favor of vxgdb versions.
3509 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3510 code dealing with byte order of values, which Intel did in host byte
3511 order rather than gdb-4's target byte order.
3512 (i960_frame_chain_valid): Move to nindy-tdep.c.
3513 (examine_prologue, skip_prologue, frame_find_saved_regs,
3514 frame_args_address, leafproc_return, saved_pc_after_call,
3515 pop_frame): Add vxgdb versions from Mark Fox.
3516 (examine_prologue, frame_struct_result_address): Add code
3517 to deal with the saved value of G13 (struct return address
3519 (frame_args_address): Modify Mark's version to prefer the
3520 saved value over the current value in the topmost frame.
3521 Cache result in the frame info to avoid performance hair in
3523 (print_fault): Add gdb960 code for printing faults.
3524 (_initialize_i960): Actually call check_host.
3526 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3527 add stub routines. FIXME, these currently just return zero!
3529 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3530 (attach_command): Call target_attach, not target_open, now.
3532 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3533 (child_attach): Rename from child_open.
3534 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3535 don't confuse it with a zero step_resume_break_address.
3537 * inftarg.c (child_detach): Eliminate inferior_pid test.
3538 (child_files_info): Clean up message a bit.
3539 (child_ops): Use child_attach, not child_open, to attach.
3541 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3542 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3543 findvar.c to here, since it depends on the contents of the
3544 shadow_contents of breakpoints, but keep if #if 0 since it is
3547 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3550 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3551 (ptype_command, display_command): Eliminate have_inferior_p and
3552 have_core_file_p in favor of target_has_stack or
3553 target_has_execution.
3554 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3555 code for actually finding the values of arguments, though we still
3556 keep track of the maximum stack offset for use in printing unnamed
3557 arguments. Handle missing FRAME_ARGS_ADDRESS.
3559 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3560 (struct nindy_regs): Define registers passed to/from nindy.
3561 (nindy_fetch_registers, nindy_store-registers): Translate between
3562 nindy and GDB formats for the registers.
3563 (dcache_init): Statically allocate the cache, since it was being
3564 allocated by a malloc that was never freed anyway.
3565 (nindy_create_inferior): Error, not core dump, if no exec file.
3566 (nindy_before_main_loop): Use target_load, not target_add_file.
3568 * remote-vx.c (net_load): Specify large timeout for load
3569 requests. Allow user to break out with INTERRUPT.
3570 (net_break): Remove useless code, clean up. Change callers.
3571 (parse-args, skip_white_space, find_white_space): Clean up arg
3572 parsing to cope with quoted strings.
3573 (net_wait, net_quit): Never call error, just return status.
3574 (vx_read_register, vx_write_register): Cleanup status checking.
3575 #ifdef the code based on which CPU we are using (960 or 68k),
3576 FIXME, this should be completely general but it isn't yet.
3577 (vx_xfer_memory, vx_resume): Cleanup status checking.
3578 (vx_run_files_info): Improve message.
3579 (vx_load_command): Renamed from vx_add_file_command. Allow load
3581 (net_ptrace): Remove unused routine.
3582 (vx_wait): Adopt code from vxgdb960 to cope with broken
3583 connections to target machine and prompt to disconnect. Remove
3584 debug printouts. Map some EVENT_'s to SIGnals.
3585 (add_symbol_stub, vx_open): Print names of object files we found,
3586 and "ok" if we read their symbols OK. Clarify output in general.
3587 (vx_attach, vx_detach, vx_kill): Add these commands.
3588 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3589 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3590 "info files" output, and create_inferior, since we already have
3593 * stack.c (frame_info): Replace Frame_unknown with 0.
3594 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3595 (return_command): Pop until the PC matches as well as the FP,
3596 so it works even if the FP is shared with another function,
3597 as in "frameless" or "leaf" procedures.
3599 * symfile.c (load_command): renamed from add_file_target_command.
3600 (add_syms_addr_command): renamed from add_file_addr_command.
3601 (add_syms_command): Stub to call target_add_syms.
3602 (_initialize_symfile): Change command names and descriptions,
3603 add-file => add-syms, and load from alias to its own command.
3605 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3606 maybe_kill_then_create_inferior): Default for attempts to start
3607 a process, if one is already running, is to ask about killing
3608 it and retry if yes.
3609 (upstack_create_inferior): #if-0 it, strata obsolete it.
3610 (push_target, unpush_target, pop_target): to_close() a target
3611 before unstacking it.
3612 (target_info): Renamed from target_files_info.
3613 (_initialize_targets): Rename "i files" as "i target", accessible
3616 * target.h: Improve comments about the target_ vectored routines.
3618 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3619 Convert commenting style to standard GNU style.
3620 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3621 (SKIP_PROLOGUE): No longer a no-op.
3622 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3623 (*_REGNUM): Sort register numbers.
3624 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3625 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3626 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3627 are now 10 byte extendeds, not 8 byte doubles.
3628 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3629 for nindy versus vxworks targets. FIXME, this should possibly go
3630 in the target vector.
3631 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3632 frame_saved_regs and arg pointer with each frame.
3633 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3634 (FRAME_ARGS_ADDRESS): Use cached result.
3635 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3636 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3637 (PRINT_RAMDON_SIGNAL): Call print_fault.
3638 (POP_FRAME): Now works.
3640 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3641 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3642 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3643 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3646 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3647 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3649 * valarith.c (value_subscripted_rvalue): Avoid handling
3650 floats and doubles specially; it gave alignment errors. Lint.
3652 * valops.c (value_of_variable, value_of_this): Error if unknown
3655 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3656 to avoid alignment problems.
3657 (value_print): Handle unknown value address.
3658 (cplus_val_print): Two args are ignored; remove them. Change caller.
3659 (val_print): Use unpack_long rather than pointer-deref.
3662 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3663 to avoid alignment problems.
3664 (value_being_returned): Error if return value unknown.
3665 (set_return_value): Add bogosity warning, FIXME. *
3667 * TODO: A woman's work is never done.
3669 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3670 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3671 Add ieee-float.o to OBS.
3672 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3673 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3674 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3676 Changes to generalize the VxWorks RPC protocol slightly, to handle
3677 i960 as well as 68000.
3679 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3680 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3681 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3682 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3683 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3684 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3685 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3686 so they will move in target byte order rather than network
3687 byte order (happens to be the same).
3689 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3691 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3693 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3696 Add contribution lines to various files, showing where they
3699 * breakpoint.c (break_insn, check_break_insn_size,
3700 read_memory_nobpt): Remove to mem-break.c.
3702 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3705 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3706 entry has bad register number. This change is not
3707 tested in this release, FIXME.
3709 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3712 * value.h: Force value's contents field to be aligned to hold
3713 at least a double or a long long (if supported). This avoids
3714 doing bcopy's in and out of the contents field.
3716 (step_1): Avoid coredump under obscure circumstances when we
3719 * symtab.h (misc_info): Add field to misc function vector for
3720 any kind of cached information the target code desires. AMD
3721 29000 uses this to avoid repeating examine_function_prologue's.
3723 * coffread.c: Lint. Remove static symfile, read_section_header.
3724 core.c (have_core_file_p): Lint: remove.
3725 expprint.c (print_subexp): Lint.
3726 infptrace.c, valops.c, valprint.c: lint.
3728 Roll in changes from vxgdb-5.0.1:
3730 * symtab.h: Comment byte order of each address class. Add
3731 LOC_LOCAL_ARG for frame-relative args (960).
3732 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3733 symtab.c, symmisc.c: ditto.
3735 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3737 * remote.c (remote_resume): Error if resume with a signal.
3739 * symfile.c (prim_record_misc_function): Clear misc_info.
3740 (fill_in_vptr_fieldno): Check stub type of arg.
3742 * valops.c (value_cast): Avoid looking up names of types whose
3743 name we don't know, to prevent coredump. Sun CC produces typedef
3744 rtx and the name of *rtx is zero...
3746 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3748 Roll in changes from final AMD 29000 port (Tiemann).
3750 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3751 for ../include/a.out.encap.h. This might not work now that BFD
3752 is separately compiled. Instead, BFD support for encap will have
3753 to translate machine type 29k into the right COFF_MAGIC.
3755 * infcmd.c: Remove references to inferior_pid that aren't used
3756 in actual ptrace calls; use target_has_execution, etc.
3757 (have_inferior_p): Remove function.
3758 (program_info): Print target info rather than "process number";
3759 avoid gratuitous messages unless from_tty.
3760 (run_stack_dummy, finish_command): Set proceed_to_finish.
3761 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3762 main.c: Lint. Lose have_inferior_p().
3763 inferior.h (have_inferior_p): Remove, lint.
3764 (proceed_to_finish): Add flag to ask that all regs be saved
3765 by normal_stop, for the few commands that need it, speeding up
3766 serial I/O. Add comments to stop_registers.
3768 * remote-eb.c: Remove newline from breakpoint message we grep
3769 for. Never time out when running the user program.
3773 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3775 Roll in changes from vxgdb-5.0.1:
3777 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3778 symbol in its raw form, we are processing an unlinked ".o" file.
3779 See if the target environment has assigned it an address, using
3780 target_lookup_symbol (VxWorks does), and enter it into the symtab
3783 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3784 68k versions for a simpler version that assumes zero FP at bottom.
3785 Fixes bug of truncated stack reports.
3787 * target.h (target_lookup_symbol): Define this routine's args
3788 and result, finally.
3790 * target.c (nosymbol): Default routine for target_lookup_symbol.
3791 (target_default): Default lookup_symbol and call_function too.
3792 (files_info): Only print has_all_memory warning if a non-dummy
3795 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3796 vx_convert_from_virtual): If target does not have floating point,
3797 zero register "values", and avoid doing cross-net conversions.
3798 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3799 (vx_open): Rearrange code that attaches to target and reads
3800 symbols for all loaded modules, to work if some of the modules
3801 are not accessible. Add symbol_stub() and add_symbol_stub()
3802 as callbacks from catch_errors(). Allow connect attempt to be
3803 interrupted painlessly with ^C (FIXME, there are still some bugs
3804 if the interrupt happens during symbol reading.). Print
3805 final message with puts_filtered, since symbol messages are
3810 * main.c (catch_errors): Only print errstring if non-null.
3811 (command_loop): Avoid an ioctl per command to test ISATTY.
3813 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3814 (vx_xfer_memory): Return correct result!
3815 (vx_files_info): Indicate whether target has float or not.
3816 (vx_lookup_symbol): Complain, not error, if target gone.
3817 (vx_open): Print "Connected" msg before disabling immediate-quit.
3818 [FIXME: lookup_symbol and vx_open changes need testing.]
3820 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3821 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3822 contributor lines and update copyrights to 1991.
3824 Changes from an attempted H-PUX host port:
3826 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3827 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3828 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3829 * remote-vx.c: include <sys/time.h> for HPUX.
3830 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3831 "core_file_command" routine to BFD regime. May not work yet.
3833 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3835 * xgdb.c: Replace X10 version with some VJ version.
3836 (FIXME: Its copyright assignment is not on record.)
3837 * xgdb.c: Update include files to X11R4 (Xaw crud).
3838 (xgdb_display_source, create_text_widget): fix call to
3839 get_filename_and_charpos. Rewack source window stuff for X11R4
3840 (gleaned from include files, and "nm's" of binary libraries, since
3841 I had no doc available).
3842 (append_selection, append_selection_word): Disable with FIXME
3843 since R4 changed interface here.
3844 (create_buttons): Add back the old set of buttons.
3845 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3847 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3848 Roll VERSION to 3.94 (not yet final though).
3850 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3852 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3853 obstack_int_grow, obstack_int_grow_fast): Eliminate
3854 cast on left of assignment, which gives MIPS cc fits and is
3857 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3858 F_ALIAS. Use printf, not fprintf, when not passing a file
3860 (compare_opcodes): Check that identical instructions have
3861 identical opcodes, complain otherwise.
3863 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3864 was reported by Roland McGrath.
3865 (unimp): Only match if exactly zero instruction. (Roland)
3866 (branches and traps): Generate all variations of these
3867 instructions with macros, based on a single call that defines
3868 each condition name and its binary representation.
3869 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3871 * valprint.c (val_print_fields): Take, and use, format parameter.
3872 This means that "p/x struct" again prints the elements in the
3873 desired format. Changed callers.
3875 * stack.c (frame_info): Use filtered output, and indicate wrap
3876 points. Remove kludgy formatting designed to avoid line wrap.
3878 * utils.c (wrap_here): If the line is already full (because
3879 we had printed a long indent or long wrapped string), do an
3880 immediate newline-and-indent.
3882 * m68k-pinsn.c (print_insn_arg): Bugfix from
3883 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3884 instruction is incorrectly disassembled as bkpt #8.
3886 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3887 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3888 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3889 and then will dump core (sometimes). I traced it back to an
3890 uninitialized symfile_name in psymtab_to_symtab.
3891 (const_vol_complaint): Add quotes to message.
3892 (define_symbol): Only believe line number if gcc_compiled.
3893 Avoid allocating symbol if we will not return it.
3895 Add target strata support so that newly established targets go
3896 into their right place in the target stack (e.g. a new exec file
3897 doesn't wipe out the ability to access the running process).
3899 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3900 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3901 and initialize it properly in all the targets.
3903 * target.h: Document strata. Change return type of push_target.
3905 * target.c (nomemory): new function for dummy memory access.
3906 (tcomplain): Rename complain, now also used in symfile.c.
3907 (push_target): Push targets within strata. New return value shows
3908 whether new target is on top of stack or not. Always keep dummy
3910 (target_files_info): Ignore dummy target.
3912 * core.c (core_open): Warn user, and skip accessing file, if the
3913 core target is not the topmost target in the stack.
3914 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3917 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3918 target_ops, it doesn't belong there since we have no regs there.
3919 Change name of target from machine => memory to clarify.
3921 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3923 * Freeze version 3.93 for release.
3925 * Makefile.dist: Handle vx-share and nindy-share subdirs
3926 properly when building gdb.tar.Z.
3928 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3929 printed in various places, so I could change just one copy.
3931 * dbxread.c, coffread.c: Change references to bfd->iostream
3932 to cast to FILE *, now that BFD avoids needing types defined
3933 in other header files.
3935 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3937 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3938 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3939 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3940 (actually gcc -Wall).
3942 * dbxread.c: Remove first_global_sym, last_global_sym, since
3943 they are never referenced.
3945 * defs.h (baud_rate): Declare.
3946 main.c: Define it, and add the -b option to set it.
3948 * gdb-int.texinfo: Add text on how to define a new host or target
3949 architecture, prompted by Per Bothner's questions about MIPS
3952 * gdb.texinfo: Document "complaints". Change doc of -q since
3953 gdb no longer prints the copyright and blurb if you specify a file
3954 name to be debugged (just like Emacs). Add doc for Nindy-specific
3955 command line flags for specifying target serial port and such.
3956 Update copyright to 1991.
3958 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3959 has taken over for us the job of ripping up executable files. The
3960 crud caused Per Bothner's port to not compile.
3962 * infrun.c (normal_stop): Avoid printing "Program exited
3963 normally" if we are in batch mode. This allows a GDB which
3964 executes a program on a target system, to behave like a Unix
3965 command (input from stdin, output to stdout, no extraneous
3968 * main.c (main): Allow additional machine-dependent command line
3969 options to be specified with the ADDITIONAL_OPTIONS,
3970 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3971 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3972 processing to occur just before the main loop with
3973 BEFORE_MAIN_LOOP_HOOK.
3974 (main): If a "core file" argument is specified, and it is not a
3975 core file, try it as a process ID to attach.
3976 (symbol_completion_function): Attempt to cope with
3977 "show screen-" TAB, not very successfully. This needs more work,
3979 (batch_file): New function, returns whether we are reading
3980 commands from an interactive tty on stdin, or from somewhere else.
3981 Called by normal_stop since it doesn't get from_tty passed down
3982 to it like many commands do.
3984 * remote-nindy.c: Handle command line options for nindy
3986 (nindy_before_main_loop): Prompt user for tty name if they
3987 don't specify it before getting to the interactive command loop.
3989 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3990 and -r command line options. Also add hook before main loop
3991 to make it easy to specify a tty.
3993 * TODO: More things to do, one done.
3995 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3997 * dbxread.c: Make complaint() calls pass pointer, not struct.
3998 Add complaints about badly formatted C++ type information
3999 (const/volatile indicator, and parse errors resulting in
4000 error_type). Fix C++ virtual member fn comment.
4001 (read_struct_type): Avoid bumping pointer if we got a parse
4002 error; this prevents our walking beyond the end of a string.
4003 Terminate loop on null char as well as semicolon.
4004 (process_one_symbol): Fix the LBRAC fix so that it uses the
4005 last previous SLINE, FUN, or SO record's PC address. C++ debug
4006 symbols did not have SLINE records in a useful order compared
4007 to the LBRAC records.
4008 (define_symbol): Handle "catch" records.
4010 * symtab.c (check_stub_type): Added new complain
4011 `stub_noname_complain' and added a consistency check to
4012 keep the debugger from crashing when finishing from an
4013 exception frame. A real fix will be needed later.
4015 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
4017 * infcmd.c (attach_command): Make global.
4019 * Makefile.dist (REMOTE_OBS): Make these compile by default,
4020 but make them easy to comment out. Perhaps later they should
4021 be enabled by what CPU you configure for? FIXME.
4022 (VERSION): Roll to 3.93.
4023 (pinsn.o): Remove rule for obsolete file.
4024 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
4026 Run down a problem that manifested by printing the wrong function
4027 name in stack traces of read_ofile_symtab. Turned out that the
4028 problem was the SunOS 4.1.1 (and previous) C compiler outputs
4029 the LBRAC symbol with an address in the *data* segment, which
4030 blew our binary search through the blocks.
4032 * dbxread.c: Use the complain() facility consistently to bitch
4033 about problems in the symbol file we are reading.
4034 (finish_block): Add code to check the nesting of the blocks;
4035 complain and Procrust them to fit if wrong.
4036 (make_blockvector): Check the order of the blocks, complain
4037 [but don't cope] if wrong.
4038 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
4039 symbols to be sure their PC value is greater than the last SLINE
4040 (line number) symbol we've seen, complaining and adopting the
4041 SLINE PC value if wrong.
4043 * symfile.h (struct complaint, complaint_root, complain,
4044 clear_complaints): Add.
4045 * symfile.c (complain, complaint_root, clear_complaints): Add
4046 facility to deal with non-fatal complaints and to regularize their
4048 (symbol_file_add): Clear complaint counters to allow new complaints.
4049 (initialize_symfile): Add 'set complaints' and 'show complaints'.
4051 * dbxread.c (dbx_symfile_read): Remember the address and size
4052 of the string table for the main symbol file, so we won't read it
4054 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
4055 to avoid reading the string table yet again. Lint.
4056 (throughout): Improve filtered output, including word wrap.
4057 (read_range_type): Improve Bothner's fix to handle other types too.
4059 * utils.c: Improve line wrap implementation. Handle unlimited
4060 width by making chars_per_line unsigned.
4061 (puts_filtered): New, easy, function.
4063 * defs.h (puts_filtered): add.
4065 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
4066 call the identical sort_symtab_syms() in symfile.c instead.
4068 * expread.y: Suggest the `file' command rather than `symbol-file'.
4070 * command.h (enum var_types): Add zinteger for seroable
4072 * command.c (do_setshow_command): Handle var_zinteger. Restructure
4073 nested if's into a switch.
4075 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
4076 we did not stop because of a breakpoint (it must have been for
4077 some other reason, like a "stepi"), so don't print anything.
4079 * symtab.c: Include <sys/types.h> all the time. Now that BFD
4080 doesn't include <sys/types.h>, old SunOS's require it for
4083 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
4085 A test port of gdb-3.92.6 to the Sony NEWS.
4088 Don't normally link in remote- or vx stuff.
4089 Some of it doesn't compile, and it wastes space for 99% of the users.
4090 Remove reference to no-longer-used HAVE_VPRINTF.
4091 Fixed BFD_DEP typo to BFD_DIR.
4093 Fix cast in arg to bfd_h_getlong.
4094 Make char *prefix be const.
4095 Fix how certain range types are mapped into builtin unsigned int types.
4097 Remove 2 #includes. They cause errors (on Sony, at least),
4098 and aren't needed (they wern't in earlier versions).
4100 print_address_symbolic should never demangle labels
4101 (since it prints *assembler-level* labels).
4103 [This was superseded by the change to printcmd below.]
4106 Add some "volatile" return types to avoid warnings.
4107 If MISSING_VPRINTF add vprintf function and not just macro
4108 (since vprintf is used in printcmd.c).
4110 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
4111 (The latter isn't grokked by some PCC-based compilers.)
4113 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
4115 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
4116 * nindy-share/coffstrip.c
4117 Added some forward declarations (otherwise, gcc complains
4118 about implicit extern redefined as static).
4120 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
4122 Changes inspired by Per Bothner:
4123 * printcmd.c (print_address_symbolic): Take additional parameter
4124 specifying whether to demangle.
4125 (print_address): Pass in asm_demangle to control demangling.
4126 (print_address_demangle): New fn, takes explicit arg to control
4128 * utils.c: Add new vars demangle and asm_demangle, and let them
4130 (fputs_demangled): If !demangle, just print the argument.
4131 (fprint_symbol): If !demangle, just print raw symbol.
4132 * valprint.c (val_print): Call print_address_demangle rather than
4133 print_address, to cause demangling to depend on the global
4134 rather than assembler-level demangling setting.
4135 * WHATS.NEW, gdb.texinfo: Document.
4137 * main.c (show_command): Show all settings if no arg.
4138 (initialize_main): Make "info set" the same as naked "show".
4139 * command.c (cmd_show_list): Handle prefix commands in the
4140 list, and print the name of the setting as well as its English
4141 description and value.
4143 Allow gdb functions to specify where a line should wrap if it
4144 exceeds the size of a terminal line. Use it to make the output
4146 * utils.c (set_screen_width_command): New fn, mallocs a buffer
4147 of the right size when screen width changes.
4148 (set_screensize_command, screensize_info): Remove #if 0'd fns.
4149 (wrap_here): New fn, indicates a point in the output where we
4150 should wrap the line rather than just letting it overflow at a
4152 (fputs_filtered): Implement wrapping.
4153 (n_spaces): New fn, returns a pointer to N spaces.
4154 (print_spaces_filtered): Use n_spaces.
4155 * defs.h (n_spaces): Declare.
4156 * stack.c (print_frame_info): Wrap with 4-space indent after
4157 fn name and before filename and line number.
4158 * printcmd.c (print_frame_args): Wrap with 4-space indent
4159 before each argument name is printed.
4160 * valprint.c (value_print): Wrap with no indentation before
4162 (val_print_fields): Wrap with indentation relative to nesting
4163 level before each field name.
4164 (val_print): Wrap with nesting indentation before array elements.
4165 * command.c (do_setshow_command): Avoid extra newlines,
4166 wrap with 4-space indent around values printed, end with period.
4167 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
4169 * breakpoint.c (breakpoint_1): Implement addressprint for
4170 "info breakpoints" display. Change file name and line number
4171 format to " at file:nnn" rather than " (file line nnn)".
4172 * gdb.texinfo: Document.
4175 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4177 Frozen for gdb-3.92.6 release.
4179 README, WHATS.NEW: Update for 3.92.6 release.
4181 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
4182 coffread.o from configs since it is now built by default.
4183 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
4184 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
4185 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
4186 from configs since it is now built by default.
4188 Makefile.dist: Update for release 3.92.6. Handle files that
4189 have been moved to ../include, ../getopt, or ../bfd. Add
4190 saber.suppress and tests directory. Add config.status to
4191 the release (it will say "none").
4193 coredep.c: Minor formatting fixes.
4195 These changes were made in early December but only checked in now:
4196 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4197 nindy-share/nindy.c: lint
4198 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4199 register values coming back from the target; we store values
4200 in target byte order everywhere.
4202 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4204 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4206 * valprint.c (cplus_val_print, val_print_fields): New functions,
4207 which print C++ objects. They conspire to avoid printing a
4208 virtual base class more than once, following all the twists and
4209 turns of C++ virtual base rules.
4210 (val_print): Call the above rather than do it by hand.
4212 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4213 symbol file, not for added files like shared libs. This really
4214 needs to be generalized to a timestamp per file.
4216 * core.c (cleanup_core): Avoid coredump if no core file.
4218 * config.gdb: Accept -host or -target in place of +host or
4221 * coffread.c (find_linenos): Avoid desupported BFD interface
4222 to line numbers. We still read them manually rather than using
4223 BFD's "generic" features.
4225 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4227 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4229 * Makefile.dist: Eliminate use of $< in explicit targets.
4231 * readline/Makefile: Use $< rather than $*.c, which does not
4232 include the VPATH in GNU Make.
4234 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4235 copies of tconfig/i960, added for global configuration
4236 compatability. All i960 versions can read both coff and b.out.
4238 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4239 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4242 * TODO: Think of more things to do.
4244 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4246 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4247 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4248 64-bit float conversion.
4250 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4251 equivalent to sun?os4 so global config works.
4253 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4255 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4257 * main.c: Only declare linesize once; declare pagesize not at
4258 all, since it is never used.
4259 (main): Clear newly allocated line before it is used.
4261 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4263 Further stabilization for the Intel 960.
4265 * Makefile.dist: Parameterize the location of the "include"
4266 and "bfd" directories, as well as "getopt". Add symfile.c.
4267 Link in both dbxread and coffread. Fix up "make depend" to
4268 rewack the locations of include, bfd, and getopt in its output.
4270 * README: Document moving include files, improve some of
4273 * coffread.c: Move common code out to symfile.c. Change
4274 symbol_file_command style interface to use new *_symfile_init
4275 and *_symfile_read interface under BFD. Use BFD internal
4276 info to locate line table, symbols, etc.
4278 * core.c (core_fetch_registers): Rename to get_core_registers
4279 to avoid confusion with fetch_core_registers.
4280 (register_addr): Move to coredep.c, which is already machine
4281 dependent. This leaves core.c pretty clean of dependencies.
4283 * coredep.c (register_addr): Accept this routine from core.c.
4285 * dbxread.c: Move common code (with coffread.c, etc) into new
4286 symfile.c. Each psymtab now contains a pointer to the
4287 format-dependent function that knows how to read it in. Make
4289 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4290 (process_one_symbol): Add code to complain about a "compiler bug
4291 we muzzle here", if we actually see it.
4293 * eval.c (evaluate_subexp): Insert missing "break" statements
4294 in code that determines whether a variable is an lvalue in
4295 memory, register, or whatever. I detected this via a compiler
4296 bug in which it *almost* mashed out the whole switch statement.
4298 * gdb-int.texinfo: Add minor sections on configuring gdb for
4299 release, and about the README file.
4301 * infcmd.c (registers_info): Fix formatting somewhat. Still
4302 not as pretty as before, but it handles byte swapping.
4304 * remote-nindy.c: If data cache routines are interrupted while
4305 waiting for the remote end, be sure that any uninitialized cache
4306 blocks are on the free list, not on the valid list!
4308 * symfile.h: Flesh out this header file with all the various
4309 routines and variables that have been merged in from dbxread.c
4310 coffread.c, and symtab.c to symfile.c.
4312 * symfile.c: New file, containing code common to dbxread.c,
4313 coffread.c, and some code from symtab.c. All generic code for
4314 reading symbol files should be in here now.
4315 (unrecord_misc_function): Remove unused function.
4317 * symtab.h: Remove file-reading things to symfile.h.
4319 * symtab.c: Remove file-reading things to symfile.c.
4321 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4322 to decode i960 fault types.
4324 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4325 target.c: Change type of the "resume" function from int to void,
4326 since its result was never used.
4328 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4330 * main.c: Replace "stupid" with "caution"; you now "set caution
4333 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4335 * infcmd.c (do_registers_info): Call val_print to deal with the
4336 byte order of the registers being printed. FIXME, this makes
4337 the formatting of the output uglier.
4339 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4340 defined, call it for signals the debugger doesn't itself use.
4341 The i960 uses this for more detailed fault information.
4343 * remote.c (remote_open): If arg is null, print help rather than
4346 * sparc-xdep.c (register_valid): Avoid declaring size, since
4347 various modules will think of various sizes depending on the
4348 architecture of their tm-file. FIXME, we need protection against
4349 actually entering one of those modules, which would clobber
4350 storage if not for the target architecture compiled into gdb.
4352 * stack.c (up_command, down_command): Always print the frame
4354 (up_silently_command, down_silently_command): New commands
4357 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4359 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4360 more parameters than it used to.
4362 * findvar.c (registers): Increase slop to 256 bytes, which should
4363 protect us against even most RISC machines with large register
4365 (locate_var_value): Move declaration inside related ifdef.
4367 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4368 throughout, to avoid throwing away buffered input from the board.
4369 (nindy_wait): Supply_register takes addr_of_value, not value.
4370 (i960_print_fault): Renamed from i80960_fault.
4371 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4372 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4374 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4375 we can set the PC in the call to proceed(). Unpush nindy_ops
4376 before pushing it on top, to avoid message to user. Eliminate
4377 commentary from Unix machines that just misleads here.
4378 (reset_command): Fix error message to suggest target command.
4380 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4382 Release 3.92.5 as frozen.
4384 Stabilize the merged release...with help from lint, Saber C,
4387 Everywhere: Add include files needed to declare return types
4388 of functions called.
4390 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4392 * breakpoint.h: Add undeclared breakpoint functions, and some
4393 functions for display handling since I couldn't think of a better
4396 * breakpoint.c (insert_breakpoints): Make code for disabling
4397 shared library bkpts more likely to work. It's used when we
4398 rerun a program and stop before the shared library has been
4400 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4401 cast from pointer, so it squeezes through catch_errors.
4402 (bpstat_stop_status): Fix logic broken some time ago. We now
4403 always create a bpstat if the stop address matches a breakpoint,
4404 even if we don't stop there -- just like the old code used to do
4405 before I got my fingers into it (sigh).
4406 (breakpoint_1): Print "ignore count" after "stop only if"
4407 condition, since that's how it actually works.
4408 (mention): Handle watchpoints as well as breakpoints.
4409 (watch_command): use set_raw_breakpoint and mention to do most
4410 of the work (and initialize all the fields!). Only pass one
4411 arg to parse_c_expression, since that's all it takes.
4413 * command.c (not_just_help_class_command): Rename arg to args
4414 since we ignore "unused argument" warnings on vars named "args".
4415 inflow.c (child_terminal_info): ditto.
4416 infptrace.c (kill_inferior): ditto
4417 main.c (catch_errors, version_info, quit_command, pwd_command,
4418 source_command, dump_me_command, editing_info,
4419 set_history_size_command, set_history, show_history,
4421 stack.c (locals_info): ditto
4422 target.c (target_files_info): ditto
4423 valprint.c (set_input_radix, set_output_radix): ditto
4425 * core.c: Remove old variables for handling core and exec file
4426 sections (data_start, data_end, stack_start, stack_end,
4427 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4428 text_end, exec_data_start, exec_data_end, text_offset,
4429 exec_data_offset, data_offset, stack_offset). They're
4430 superseded the more general build_section_table and
4432 (get_exec_file): Mention the `file' command.
4433 (read_memory_check): Rename to memory_error, and only call it
4434 in the case of an actual error.
4435 (read_memory, write_memory): call memory_error.
4436 (core_fetch_registers): Register section name is ".reg".
4438 coredep.c: Remove a bunch of crud now that all this file does
4439 is pull the registers out of a core file.
4440 (fetch_core_registers): Rewrite to actually work, I hope.
4442 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4443 Replace index() with strchr(). Remove all the pre-BFD macro
4444 definitions for accessing the symbol file.
4445 (struct dbx_symfile_info): Encapsulate the information that
4446 dbx_symfile_init needs to pass to dbx_symfile_read in this
4449 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4450 dbx_symfile_discard): Rearrange symbol file reading to divide
4451 the format-specific part from the format-independent part,
4452 leaving the format-independent part such as file name expansion
4453 and opening in symtab.c. This replaces
4454 partial_symbol_file_open and partial_symbol_file_read.
4455 Symbol_file_read, add_file, add_file_target_command,
4456 add_file_addr_command move to symtab.c. Pass an explicit
4457 "mainline" flag for when reading the main symbol table, rather
4458 than relying on the offset address to be zero or nonzero.
4460 (dbx_symfile_read): Don't allow void *'s to be printed as
4462 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4463 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4464 macro" debug version really work.
4465 (read_dbx_symtab): Remove unref'd parameter inclink.
4466 Avoid swapping N_SLINE symbols, for speed.
4467 Merge N_TEXT!N_EXT case with the other external symbol
4468 definitions' case. Add comments.
4469 (start_psymtab): Allocate the symfile name in the psymtab on
4470 the psymbol_obstack, rather than using the caller's storage.
4471 (end_psymtab): Only allocate a dependencies list if there are
4473 (psymtab_to_symtab_2): Use BFD when reopening file to read
4474 its symbols for real.
4475 (read_struct_type): Add FIXME comments where it needs work
4477 (read_huge_number): Add FIXME about overflows.
4478 (read_range_type): Add FIXME about comparing a long to 1<<32.
4480 * coffread.c: Minor changes to move things closer to the new
4481 regime with symtab.c and dbxread.c Major work is still needed
4484 * exec.c (exec_file_command): Remove old variables (see core.c
4486 (xfer_memory): If memory transfer is right at the end of a
4487 section, don't lose.
4489 * findvar.c (get_saved_register): If value is in a real
4490 register, LVAL is lval_register, not lval_memory.
4492 frame.h: Declare print_sel_frame and record_selected_frame.
4494 gdb-int.texinfo: New file, for GDB internals documentation.
4495 Very simple, unformatted doc of cleanups is there for now.
4497 gdbcore.h: Remove obsolete variables that described a.out
4498 section addresses and offsets. (See core.c above.)
4499 Declare fetch_core_registers and registers_fetched.
4501 getopt.c: Declare char *alloca(); even on SPARC.
4503 infcmd.c (run_command): Call target_kill rather than
4505 (step_command, next_command, stepi_command, nexti_command):
4506 Declare from_tty parameter even though we don't use it.
4507 (run_stack_dummy): argument BUFFER is a char array, not
4508 a pointer to REGISTER_TYPE.
4509 (finish_command): using_struct_return needed a value *,
4510 not a struct symbol *.
4512 * infptrace.c (child_xfer_memory): To avoid dependency on
4513 where sections are in memory, try PT_WRITE_D and if that fails,
4514 try PT_WRITE_I. Most Unixes don't care which you use.
4516 * infrun.c (step_resume_break_shadow): Change to array to
4517 match other breakpoint shadow storage.
4518 (clear_proceed_status): Pass address of bpstat to
4519 bpstat_clear, not the bpstat itself.
4520 (child_create_inferior): FIXME comment about if the child
4522 (start_inferior): Remove old function.
4523 (child_open): Use target_kill rather than kill_inferior.
4524 (wait_for_inferior): Ditto.
4525 (insert_step_breakpoint, remote_step_breakpoint): Use
4526 new step_resume_break_shadow.
4528 * inftarg.c (child_wait): If all child processes die,
4529 pretend that the one being waited for exited with signal 42.
4531 * main.c (command_line_input): When scanning for comments,
4532 don't coredump on unclosed quotes.
4533 (quit_command): Use target_kill rther than kill_inferior.
4534 (_initialize_main): Rename class_user from "user" to
4537 * printcmd.c (print_command_1): Initialize "fmt" if no format
4538 is specified by the user.
4539 (print_frame_args): Only add to args_printed if we are
4540 actually fetching args from the stack (avoiding undefined
4542 (_initialize_printcmd): Remove bogus \{ from string.
4544 * remote-eb.c (eb_open): Avoid coredump on no argument.
4546 * remote-nindy.c: Bring out of Intel environment into new
4547 target environment. Remove all conditional compilation on
4548 I80960. Massive hacking throughout.
4549 (nindy_xfer_inferior_memory): New routine stolen from
4551 (nindy_create_inferior): New routine pieced together, probably
4552 not quite working yet.
4553 (nindy_ops): New target_ops struct for nindy.
4555 * remote-vx.c: Use write_memory rather than target_write_memory
4556 to get error checking.
4557 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4559 (vx_create_inferior): Use target_terminal_ours...
4561 * signame.c (_initialize_signame): Always initialize, since
4562 we need the table for things other than psignal.
4564 * solib.c (solib_add): Use symbol_file_add, not add_file.
4565 (solib_address): Return boolean result rather than struct
4566 pointer which nobody else knows the type of.
4568 * sparc-tdep.c, valops.c: Use write_memory rather than
4569 target_write_memory, to get error checking.
4571 * stack.c (locals_info, catch_info, args_info,
4572 get_selected_block, frame_command, up_command): Use
4573 target_has_stack, rather than have_inferior_p or
4576 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4578 * symfile.h: New file, defining the interface between the
4579 generic and object-file-specific symbol reading code.
4581 * symtab.c: Move generic symbol-reading interface to symtab.c,
4582 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4583 table to map BFD targets to symbol-reading modules in GDB.
4584 Change index to strchr.
4585 (lookup_struct_elt_type): Use error() rather than hand-made
4586 simulations thereof.
4587 (lookup_partial_symbol): Speedup slightly when length == 0.
4588 (symbol_file_add): New function.
4589 (symbol_file_command): Call it.
4590 (symfile_open, symfile_init): New function.
4591 (add_file_target_command, add_file_addr_command): moved from
4594 * target.c (target_command): use target_kill.
4596 * target.h (target_files_info): Don't declare, never called
4599 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4600 files to determine stack end address.
4602 * valarith.c (value_x_binop, value_x_unop): Change error message
4603 to be more useful. Pass proper argument to value_struct_elt.
4605 * valops.c (value_assign): FIXME comment that long long
4606 bitfields will break here.
4608 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4609 Update `make saber_gdb' to work better.
4611 * TODO: A woman's work is never done.
4613 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4614 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4615 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4616 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4617 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4618 valops.c, valprint.c, exec.c: Lint.
4621 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4623 Continuing Intel 960 port merge of GDB.
4625 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4626 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4627 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4628 Wack over "make depend" so it handles files in subdirectories
4629 vx-share, nindy-share, bfd, and in the current directory.
4631 * blockframe.c (get_prev_frame_info): Remove fatal error
4632 if stack not defined.
4634 * core.c (core_open, core_detach): New functions that handle
4635 the old "core-file" command as "target core" and "detach" instead.
4636 (core_file_command): Call them.
4637 (core_xfer_memory): Use common routine xfer_memory.
4639 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4640 dbxread now uses bfd for everything but symbol reading itself.
4641 BFD internals are used to drag out the relevant file offsets.
4642 (partial_symbol_file_open): Change args all around for BFD.
4644 * symtab.c: Rename "value" to "val" everywhere, so we can
4646 (symbol_file_command): New command, moved from dbxread.c
4647 and coffread.c. It uses BFD to read the file, then vectors
4648 based on its type, to dbx or coff symbol readers.
4649 * symtab.h: Extern a few vars for symbol_file_command.
4651 * target.h: Breakpoint takes a char * save area, not a char **.
4653 * valprint.c (val_print): When unpacking bitfields, offset
4654 the address in gdb of the value, if it is declared with a shorter
4655 type. Remove the last "runtime kludge test" of host byte order.
4657 * utils.c: Remove old my_bfd_read routine.
4659 * stack.c (frame_info): Use target_has_stack. Print program counter
4660 register's actual name rather than "pc", since it's called the
4661 "ip" (instruction pointer) on the i960 (sigh).
4663 * target.c (target_command): Add command for selecting a target
4664 type and calling its open routine. This is used for initiating
4665 communication with a particular target, in a generic way.
4667 * tm-i960.h: Update for modern gdb. Remove semicolons from
4668 various macros. Handle reading struct return convention, and
4669 error-out attempts to return structs with the "return" command.
4670 Be sure gdb doesn't think we know how to call functions in the
4673 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4674 to i960_xxx in lower case.
4675 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4676 not being defined yet.
4678 * remote.c (remote_open): Call start_remote to initialize
4679 wait_for_inferior during open.
4680 (remote_xfer_inferior_memory): Return length written rather
4683 * remote-vx.c (target_command -> vx_open): Use new generic
4685 * remote-eb.c, inftarg.c, exec.c: ditto.
4687 * infrun.c: Fix comments.
4688 (attach_program -> child_open): Use new generic target command.
4689 (wait_for_inferior): Clear saved register values before target_wait,
4690 so target_wait can set some of them if convenient.
4692 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4693 Return success indicator, not void.
4694 (child_xfer_memory): Avoid fetching initial word if we'll
4695 overwrite it anyway.
4697 * infcmd.c (attach_command): Use new generic target open routine.
4698 (_initialize_infcmd): Update doc on attach and detach commands.
4699 (do_registers_info): Merge in a byte-order problem as a FIXME
4702 * findvar.c (find_saved_register): Avoid problem in current frame.
4703 (read_relative_register): Ditto.
4704 (write_register): Convert byte order on the way out.
4706 * exec.c (file_command): Add.
4707 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4708 (xfer_memory): Common function between core_xfer_memory and
4710 (exec_xfer_memory): Use it.
4712 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4714 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4715 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4716 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4718 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4720 Merge Intel 960 port of gdb, continuing...
4722 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4723 symbol_file_command): Pass from_tty arg to hush 'em up.
4725 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4726 Add magic numbers for 960 COFF format.
4728 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4730 Merge Intel 960 port of gdb, from Intel "1.2" release.
4732 CHANGE_LOG entries from their port, which was based on

4736 Remove temp file if download is interrupted.
4738 Wed Aug 1 09:08:33 PDT 1990
4739 Now uses binary protocol to talk to NINDY.
4740 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
4741 Times out after 5 seconds when trying to talk to NINDY.
4743 Tue May 29 12:54:49 PDT 1990
4744 Added variable baud rate (-b switch).
4745 Source code reorganization.
4747 Thu Apr 26 11:09:55 PDT 1990
4748 More cleanup of batch mode; specifically, execute "-s", "-e", and
4749 "-se" switches as soon as they are encountered on the invocation line.
4751 Fri Apr 20 13:47:15 PDT 1990
4754 Thu Apr 19 09:54:28 PDT 1990
4755 Add 'reset' command.
4757 Wed Apr 18 09:48:07 PDT 1990
4758 After opening remote tty, wait for 1 second to go by without input
4759 from it before trying to talk to NINDY (fixes problems with the
4760 Heurikon HK80/V960E).
4762 Mon Apr 4 16:33:05 PDT 1990
4763 Some output was not being suppressed in 'batch' mode.
4765 Thu Mar 22 15:31:11 PST 1990
4766 Ask user if old symbol table should be deleted when new file is
4769 Allow user to run a program downloaded before gdb960 was brought up.
4771 Correct "exec-file" help message for i80960 context.
4773 Correct bug in calculating user space address: could occasionally
4774 corrupt user program.
4776 Make sure to zero low-order bits in rip's because of bug in 960CA
4777 A-step part: could cause operation faults when "next"ing across
4780 Correct bug that made it impossible to get source line numbers for
4781 code loaded at addresses higher than 0x7fffffff.
4783 Wed Jan 10 12:43:22 PST 1990
4784 Open remote tty for exclusive use.
4786 Fri Jan 5 12:14:42 PST 1990
4787 Correct disassembly (CA manual was right after all):
4788 opcode for sysctl is 0x659
4790 Mon Oct 23 12:03:04 PDT 1989
4791 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4793 Mon Oct 16 14:15:09 PDT 1989
4794 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4796 Mon Oct 2 15:56:31 PDT 1989
4798 Added 960CA disassembly support.
4800 To simplify maintenance:
4801 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4803 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4804 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4805 - made disassembly interface identical to that in gdmp960.
4809 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4811 * target.h: Allow targets to stack. Add target_has_memory,
4812 _registers, etc. Restructure memory access and "info files"
4813 to walk the target stack.
4814 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4815 target.c: Change tables to match target.h.

4820 * remote-eb.c: New memory regime, new info files.
4821 * remote-vx.c: New memory regime, new info files. Now use
4822 separate targets for VxWorks attachment to machine, and
4823 actually running a process under VxWorks, since one has
4824 stack & execution & regs and the other doesn't.
4825 * remote.c: New memory regime, new info files.
4826 * sparc-xdep.c (fetch_core-registers): New memory regime.
4827 * target.c: New routines and support for stacked targets,
4828 new memory regime, new info files regime.

4832 including use of the new BFD (binary file) library.
4833 * gdbcore.h: Add struct section_table.
4834 * exec.c (build_section_table): Iterate all sections and
4835 record what gdb needs to know about them.

4841 * source.c (find_source_lines): Use bfd_get_mtime.
4842 * dbxread.c: Quick changes to make it compile with new BFD.
4843 * utils.c (error): Avoid using bfd_error in generic routines.
4845 * core.c (core_fetch_registers): Get from the ".regs" section of
4847 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4849 * inferior.h (attach_flag): Export.
4850 * infcmd.c (run_command): use new target_create_inferior.
4851 * infrun.c (child_create_inferior): Don't return result.
4852 * Makefile.dist (VERSION): 3.91.4.
4854 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
4856 * breakpoint.c (bpstat_num): Handle breakpoints which have
4857 since been deleted, such as temporary breakpoints.
4858 infcmd.c (program_info): ditto.
4860 * core.c (core_file_command): Display the frame where the core
4865 * remote-vx.c (target_command): Merge in target command from
4866 targ-vx.c. A few other cleanups.
4868 * TODO, Projects: Lots more stuff to do...
4870 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4872 Massive changes to wall off the remote-debugging interface
4873 behind a function vector. The port to handle VxWorks targets
4874 is also part of this.
4876 All files: Replace references to renamed functions,
4877 remove references to remote_debugging, remove references to
4878 have_include_file, have_core_file in favor of target_has_stack,
4879 target_has_memory, etc.
4881 * Modularize the breakpoint interface.
4882 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4883 a breakpoint instruction.
4884 breakpoint.c: struct breakpoint's shadow_contents now sized as
4886 (insert_breakpoints): Vector to target to install breakpoints.
4887 (remove_breakpoints): Vector to target here too.
4888 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4889 sparc-tdep.c (single_step): Use new breakpoint interface for
4890 the single-step breakpoints.
4891 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4892 New file, contains routines to insert and remove breakpoints by
4893 reading out the old contents and later replacing them. This is
4894 how ptrace breakpoints work, and many remote systems as well.
4896 * tm-vxworks68.h: New config file, overrides a few things for
4897 Wind River's preferences.
4899 * target.h: New file, for transfer vector used to talk to the
4900 inferior (child, attached, core, exec, remote, etc). All accesses
4901 to the thing being debugged should come through these vectors.
4902 target.c: New file, routines to handle transfer vector.
4903 (various files): Add transfer vectors XXX_ops for the various
4904 targets and pseudo-targets (core files, etc) we support.
4906 * breakpoint.c (bpstat_stop_status): Further explorations of
4907 watchpoints and why things don't work all the time.
4908 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4910 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4911 the local gdbinit if it doesn't already have it.
4913 * core.c (core_ops): add and install.
4914 Allow core debugging without exec file.
4916 * dbxread.c (free_and_init_header_files): Merge two fns.
4917 (end_symtab): Free named symbol table when a new version comes in.
4918 (read_dbx_symtab): Relocate all kinds of symbols with base
4919 address. First step toward handling different text, data, bss
4921 (add_file_addr_command): Renamed add_file_command.
4922 (add_file_command): Vector to remote handler.
4923 Add "load" as an alias for "add-file" command.
4925 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4926 non-returning functions.
4928 * exec.c: Add exec_ops, and push it as a target when an exec
4931 * infcmd.c (run_command): Pass executable file name and arg list
4932 separately when starting an inferior. Permit "run" when no exec
4933 file is specified, for VxWorks.
4934 (detach_command): Move to child_detach in inftarg.c.
4936 * inftarg.c: New file. Unix-child-specific routines, and the
4937 child_ops structure.
4939 * inferior.h (registers): Export "registers" as the way for
4940 target dependent register handlers to find gdb's local copy of
4941 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4942 since it is now used by places that want wait_for_inferior to
4943 handle the grunge but want to see every trap from the inferior.
4945 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4946 Eliminate remote_debugging hooks in terminal handling.
4948 * infrun.c: Replace start_inferior with child_create_inferior.
4949 Move all the hair of Unix shells and ptrace idiosyncracies into
4950 child_create_inferior, so remote handlers don't have to deal.
4951 Remove running_in_shell. Rename stop_after_attach to
4952 stop_soon_quietly, and use it in a few other places where we want
4953 to just call wait_for_inferior and get control back on the first
4954 trap. trap_expected now never takes a value > 1.
4955 (init_wait_for_inferior): Initialize static vars when a new
4958 main.c (gdbinit): Add new hook for .gdbinit file name, let
4959 it be overridden by config files as GDBINIT_FILENAME.
4960 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4961 Both of these are used for VxWorks gdb.
4963 mcheck.c: rename include file "gmalloc.c" to avoid problems
4964 with system include file "malloc.c".
4966 param-no-tm.h: New include file, same as param.h but does not
4967 include the default "tm.h" file. This is used in files where
4968 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4970 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4972 remote-vx.c: New file, VxWorks remote debugging support. Uses
4973 RPC routines that are shared with the target system, in directory
4976 remote.c: Vectorize remote interface.
4978 source.c: Globalize source_path, and make an alias "l" for "list"
4979 since we now have the "load" command.
4981 sparc-xdep.c: Use new param-no-tm.h.
4983 symmisc.c (free_named_symtab): Add new function from Wind River.
4984 However, ifdef it out for now while we think about what it should
4987 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4989 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4990 non-Unix-children handle this with their own code in the target
4993 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4994 source and target lists. Add vx-share to default list of include
4995 directories. Add new files to src and target lists: mem-break,
4996 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4997 ${srcdir} versions of munch and createtags are used.
4999 * valops.c (find_function_addr): Split out of call_function.
5000 (call_function_by_hand): Rename call_function; this function
5001 calls functions in the target by laboriously patching the target
5002 word-by-word with the right stack, args, regs, etc.
5005 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
5007 Handle AMD 29000 a bit better.
5009 * remote-eb.c (readchar): Mask received char log to make it readable.
5010 (remote_start): Pass arguments down to executing program.
5011 Make startaddr unsigned.
5012 infrun.c (start_inferior): Accept args, pass them to
5014 infcmd.c (run_command): Pass args down to start_inferior.
5016 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
5017 the target object file format.
5018 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
5020 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
5021 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
5023 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
5025 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
5026 * TODO: We did a few things, we have more to do though.
5028 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
5029 * inflow.c (inferior_died): Clear deferred stores.
5031 * Debug problems with dummy frames and calls to the inferior.
5032 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
5033 * sparc-tdep.c (do_restore_insn): Simplify.
5034 (sparc_frame_find_saved_regs): Simplify and fix what we find.
5035 (sparc_push_dummy_frame): Simplify and fix what we push.
5036 (sparc_pop_frame): Slightly more hair here, deciding whether
5037 we are restoring a saved PC or returning to a return address in %i7.
5038 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
5040 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
5041 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
5042 * obstack.h (chunkfun): ditto.
5043 * defs.h (xmalloc, xrealloc): ditto
5045 * utils.c (quit): Grab the terminal from the child if necessary.
5047 * inflow.c (term_status_command): Rename to term_info, change
5050 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
5051 (is_delayed_branch): Speed up.
5052 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
5053 Still missing some float ops, and needs testing.
5055 * Support for input and output radixes other than base 10
5056 * defs.h (input_radix, output_radix): Declare.
5057 * expread.y (yyparse, parse_number): Handle changes of input
5058 radix, and ambiguous names-or-numbers in radixes >10.
5059 * printcmd.c (print_scalar_formatted): Print formatted hex
5060 numbers in varying column widths.
5061 * valprint.c (val_print): Use output_format to print scalar ints.
5062 (set_input_radix, set_output_radix, set_radix): Create.
5063 (set_output_radix): Set output_format from output_radix.
5064 (_initialize_valprint): add `set radix' but leave the others off.
5066 * main.c (execute_command): Let stupid questions be turned off.
5067 (_initialize_main): Handle "set stupidity", etc.
5069 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
5070 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
5072 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
5074 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
5075 bfd stuff is still screwed up, but with some manual work, it
5078 * breakpoint.c (bpstat_do_actions): Start over if a command
5079 proceeds the inferior, since the inferior will have stopped and
5080 will need to have its new stop-actions taken care of.
5082 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
5083 compiler fits, simplify it.
5085 * gdb.texinfo (directory command): Doc new dir command.
5086 source.c (directory_command): "dir" now puts things on the front
5087 of the path, moves dups up front, and handles multiple names
5088 on the command line, inserting each one in order. It also
5089 blows away cached line and full_filename info.
5091 * stack.c (backtrace_command): Skip "more stack frames follow"
5094 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
5095 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
5096 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
5097 The only odd one was Gould NP1, which had defined vprintf to
5100 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
5101 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
5102 variable, inspect_it.
5103 valprint.c (print_string, val_print): Use the global inspect_it
5104 to indicate whether to print in Epoch style or normal style.
5106 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
5108 * printcmd.c (call_command): add an alias for the "print" command
5109 which runs expressions and doesn't print the result if void.
5110 (print_command_1): implement it.
5112 * command.c: Remove #if 0'd code. Initialize all the fields
5113 in add_cmd (). Rename do_nothing_command to
5114 not_just_help_class_command, and make it externally visible.
5115 command.h: add user_commands to struct.
5116 * main.c (define_command): Don't overload c->function with a char
5117 string as well as a function pointer.
5119 * eval.c (evaluate_subexp): Reinstall tiemann changes to
5120 calling convention of value_struct_elt () that got dropped in
5123 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
5124 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
5126 * tm-sparc.h (POP_FRAME): replace some constants with defines.
5128 * sparc-xdep.c (store_inferior_registers): defer stores to regs
5129 until a good time (e.g. when we are about to run the child),
5130 saving ptrace calls.
5131 * infrun.c (proceed): handle DO_DEFERRED_STORES.
5132 * tm-sparc.h: define DO_DEFERRED_STORES.
5134 * sparc-xdep.c (store_inferior_registers): when storing float
5135 registers, don't store stack regs too. When storing the SP,
5136 however, DO store the stack regs too. This fixes a bug in which
5137 the dummy frame is not recognized when a call_function finishes,
5138 because its frame pointer (in the stack regs) was never
5140 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
5141 even though we don't know how to read them from an inferior.
5142 valops.c (call_function): Comment about storing SP.
5144 * infrun.c (save_inferior_status): Save away the original bpstat
5145 chain so it can be restored later. Install the copied version for
5146 use by whoever saved the status. It will be blow away by
5147 restore_inferior_status, and the original chain restored. This is
5148 important for people who have pointers into the original.
5150 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
5151 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
5152 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
5155 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
5157 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
5158 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
5159 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
5161 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
5163 * Merge Mike Tiemann's multiple inheritance changes from Sun.
5164 Store the baseclasses in a type struct starting from array element
5165 0 rather than from the unusual array element 1.
5167 dbxread.c: the above.
5168 (virtual_context): Add
5169 Read new debug information about which virtual function table
5170 a virtual function is from, and store it in fn_field.fcontext.
5172 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
5173 TYPE_FN_FIELD_STATIC_P.
5175 symtab.c: the above.
5176 valops.c: the above. Handle pointer casts of object *'s.
5177 (search_struct_method): Add.
5178 (value_struct_elt): First arg is now a pointer to a value, and is
5181 valprint.c: the above.
5182 values.c (value_virtual_fn_field): Add type arg. Handle
5183 offsetting to the proper object when calling virtual fns.
5185 (baseclass_addr): Add valuep arg.
5187 * README: Document the current state of BFD config (missing).
5188 * TODO, ChangeLog, Makefile.dist: Roll version.
5189 * WHATS.NEW: Add summary of changes since 3.5.
5191 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
5193 * dbxread.c (read_struct_type): Clear bit vectors whenever
5195 symtab.c (B_CLRALL): define.
5197 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5198 using == rather than =. Huh... This fixes the dreaded problem
5199 wherein builtin_type_int becomes TYPE_CODE_FLT.
5201 * core.c (info_files): Show the inferior pid.
5203 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5204 already knows how to look in the source directory.
5206 * Remove psymtab hair from many places. Remove duplicated code
5207 for searching symbol tables. Hide psymtabs from most places.
5208 Make it fast to get from a psymtab to its symtab.
5210 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5211 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5212 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5213 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5214 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5215 new symtab completely. New psymtabs get symtab pointer
5216 initialized to zero. Remove MI warning printf.
5217 symtab.h: Comments. Add psymtab to symtab pointer.
5218 (PSYMTAB_TO_SYMTAB): New macro.
5219 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5220 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5222 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5224 (print_frame_info): Avoid special-casing symbols that have not yet
5227 * source.c (open_source_file): Quick path if we have already
5228 located the source file by its full name.
5230 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5231 find_pc_psymtab. When a name is found in the misc function
5232 vector, search the symbol table for its mangled name, not the
5233 name that the user typed.
5235 * bfd.h: Fix missing comment terminators, make #endifs match.
5237 * valarith.c (value_less): Handle unsigned int comparisons.
5238 Add FIXME about pointer compares, which assume host and target
5239 pointers are the same.
5241 * command.c (do_nothing_command): lint
5242 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5243 fix comments on debug symbol format for visibility. Actually set
5244 visibility of symbols.
5245 main.c (echo_command): lint; use <readline/history.h>.
5246 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5247 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5248 pointing past end of allocated memory; saber complains.
5249 obstack.h: Declare the external functions that we use.
5250 valarith.h: use <string.h>
5251 solib.c (solib_add): lint.
5253 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5255 * main.c (initialize_main): Default info_verbose to off, now that
5256 symbol reading is fast.
5257 (quit_command): Avoid clobbering exec_bfd while quitting.
5259 * Initial BFD (binary file diddling library) merger:
5260 coffread.c: Change AOUTHDR to struct exe_hdr.
5262 core.c: initialize initialized data at compile time.
5263 (core_file_command): Move from coredep.c, convert to bfd.
5264 (xfer_core_file): Convert to bfd.
5265 exec.c (exec_file_command): use bfd routines.
5267 mips-tdep.c: Remove exec_file_command and friends.
5270 * coredep.c: (fetch_core_registers) Convert core_file_command to
5271 fetch_core_registers.
5272 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5274 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5275 (my_bfd_read): More bogosity, which I don't think we call.
5276 (program_name): Remove this atrocity asap!
5278 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5281 values.c: allocate_repeat_value was not clearing the
5282 optimized_out field.
5283 (value_static_field): minor stylistic fix (wrong macro was used).
5284 valops.c (value_struct_elt_for_address): didn't work for C++
5287 * signame.c (_initialize_signame): Initialize signal names once.
5289 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5290 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5291 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5293 * remote-eb.c: Support user-settable baud rates on the serial port.
5295 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5297 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5299 * tconfig/sun3os4: Remove warning about native assembler,
5300 since it also occurs in the xconfig file.
5302 * findvar.c (registers): Allocate some slop after `registers'
5303 to prevent stray accesses from trashing the next variable.
5305 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5306 on the sun-3, by changing the #ifdef from `sun3' (which is not
5307 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5308 vars, which happened to follow `registers' in the executable.
5310 * readline/history.c (history_search): Heed gcc-2's advice
5311 and parenthesize && inside ||).
5313 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5314 tm-29k.c: Insert FSF copyright headers.
5316 * remote-eb.c: Better comments.
5318 * Makefile.dist: Update to 3.91.6.
5319 * TODO: note PREPARE_TO_STORE problem.
5321 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5323 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5325 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5327 * infrun.c (wait_for_inferior, at end): Don't set up
5328 prev_* if the inferior no longer exists.
5330 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5331 CANNOT_EXECUTE_STACK.
5332 valops.c (call_function): Use it.
5334 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5336 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5337 infrun.c (wait_for_inferior, 2 places): Use it.
5339 * values.c (value_being_returned): Only use
5340 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5342 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5343 right thing for remote-eb.c.
5345 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5346 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5348 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5349 (FRAME_FIND_SAVED_REGS).
5351 * findvar.c ({fetch,store}_registers): Check for
5352 REMOTE_{FETCH_STORE}_REGISTER macro.
5354 * findvar.c (get_saved_register): Add argument lval and
5355 change meaning of argument addr.
5356 findvar.c: Change calls to get_saved_register to reflect
5357 new calling convention.
5358 valops.c (value_assign): Use get_saved_register instead of
5359 find_saved_register.
5361 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5363 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5364 an (uninitialized) pointer to one. Use "&" when passing it
5367 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5369 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5372 * coffread.c (symbol_file_command): Put semicolon after
5374 Put safe_to_init_tdesc_context in #if defined (TDESC).
5375 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5376 coffread.c: #include <sys/stat.h>.
5377 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5378 Add missing ')' in check for "lc%" and friends. Remove
5380 Declare read_one_sym() at top of file.
5381 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5382 MC68WRMAGIC can have the same value without causing a duplicate
5385 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5387 * Allow a Makefile to be built without building the
5388 tm and xm file links that screw up builds in subdirectories.
5389 This is done with `config.gdb none', then you can do things
5390 like `make gdb.tar.Z'.
5391 * tconfig/none: Config file for no target system
5392 * xconfig/none: Config file for no host system
5393 * config.gdb: If no TM or XM files are called out by the
5394 host or target file, don't make links for them.
5396 * cplus-dem.c: Add documentation.
5398 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5399 simple error, so the user's gdb doesn't crash due to some object
5400 file problem (e.g. somebody is rebuilding the file out from under
5403 * printcmd.c (print_address_symbolic): demangle the symbol.
5405 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5406 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5407 (alldeps.mak): sort and uniq all results from this; duplicates
5408 hose gdb.tar.Z link building. Remove RCS files from
5409 tconfig and xconfig. Add config files for sun386. Add
5410 a few odd files to OTHERS and HFILES.
5412 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5414 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5415 Roll version number to 3.91.5. Make lint work in bindir.
5417 * README: Document cross-debugging and new file structure.
5419 * blockframe.c: Lint. Include "value.h" to declare read_register.
5420 (find_pc_partial_function): remove duplicate line.
5422 * command.h: Lint. Declare error_no_arg and dont_repeat.
5424 * tm-news.h: Remove inadvertently duplicated stuff.
5426 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5427 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5429 * config.gdb: Allow `config.gdb host target' form. Clean
5430 up previous change that printed bogus messages when you just said
5433 * core.c: #include "command.h" for lint.
5436 * main.c: Remove some casts of enums. Lint.
5443 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5445 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5446 read it from memory. This will allow us to save ptrace calls
5447 eventually. Changed caller single_step too.
5449 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5450 that we aren't going to use, saving many ptrace calls, especially
5451 when watchpointing or single stepping. Use some #define's for
5453 (store_inferior_registers): Ditto.
5454 (core_file_command): Use some #define's for constants.
5456 * tm-sparc.h: Add #define's for some register numbers, so we
5457 can eliminate the use of random constants in sparc-xdep.c.
5459 * stack.c (frame_command, print_frame_info, up_command,
5460 down_command) Remove frame_changed, since it
5461 causes a bug and doesn't seem to do anything useful. In some
5462 places it was used as a flag, in others as a stack level (?).
5464 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5465 default is to use the portable (vprintf) version rather than the
5467 * xm-news.h (MISSING_VPRINTF): Add.
5469 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5471 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5473 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5474 about linking debugged programs -Bstatic in the sun?os4 config
5475 files in tconfig and xconfig subdirectories.
5477 * main.c (main): Remove unreached exit(0) now that we exit
5480 * Create TODO file for online bug list. There are too many
5481 "little" bugs to keep track of on paper.
5483 * Change Projects file to refer to bug-gdb@cygnus.com
5484 rather than kingdon@ai.
5486 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5488 * Makefile.dist (VERSION): 3.91.4 now.
5490 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5491 (condense_misc_bunches): Add sanity check that misc_count is
5492 the same as the number of symbols in the bunch.
5494 * coffread.c: rename init_misc_bunches. Pass an argument
5495 to condense_misc_bunches (a zero).
5497 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5498 every time we are called; don't rely on our caller to do it.
5499 (add_file): Remove call to init_misc_bunches.
5501 * mipsread.c: Only warn, don't error, if unknown symbol types.
5502 This keeps an old gdb from falling on its face if it sees newly
5503 extended symbol info. Rename init_misc_bunches.
5505 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5507 * Merge in changes from Per Bothner for DECstations and other
5508 MIPS stuff. The rest is Bothner speaking:
5510 The next message is a merger of Alessando Forin's mips port with
5511 mine. I've tried to use my good if biased judgment to get
5512 the best of both. It *does* need testing.
5514 Some of the changes are general, *not* mips-specific.
5517 Didn't believe in little-endian bit order.
5518 There are still inconsistencies about whether flags
5519 like BITS_BIG_ENDIAN are integer (#if ...) or
5520 boolean (#ifdef ...). I tried to paper over them.
5522 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5523 Moved some misc_function code that was common to
5524 {dbx,coff,mips}read.c to symtab.c.
5525 In the process, I think I cleaned things up a bit.
5526 At the same time, moved obsavestring and obconcat to symtab.c.
5529 Removed obsolete condense_addl_misc_bunches (use
5530 condense_misc_bunches(1) instead).
5533 Needed to include <sys/dir>, at least on DECstations.
5535 valops.c, mips-tdep.c, tm-mips.h:
5536 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5537 conventions (when STACK_ALIGN is insufficient).
5538 Needed on mips, where doubles need 8-byte alignment,
5539 but ints only need 4.
5542 Removed cruft that was not being used.
5543 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5546 Print $ before register-names (I think that makes things a little
5548 Never print two instructions, even if one delays.
5549 Removed hex-disassemble set_cmd. (This is not mips-specific,
5550 so I think the argument is whether it is generally worthwhile or not.
5551 I'm inclined to think not, given how easy it is to
5552 convert between radixes in gdb.)
5555 This is basically Alessando's code.
5556 It doesn't use obstacks; I changed it to use obstacks
5557 in a few minor places where using malloc causes a
5558 memory leak. (Probably, more places could/should be changed.)
5559 I added record_misc_function where it was missing.
5560 In symbol_file_command and add_file_command, I tried
5561 to make the code consistent with more recent versions.
5562 Minor sylistic changes in parse_procedure.
5563 Make a .gdbinfo. psuedo-symbol point back to the real
5564 procedure symbol (using the isym field).
5567 This is basically from my port, but with a lot of details
5568 and a number of routines merged in from Alessando's version.
5569 I basically used my code "raw" backtrace (use heuristics
5570 from the actual code, rather than symbol table info) - though
5571 the idea is Alessandro's. I feel my code is a little cleaner
5572 here, particularly in being a little more flexible, such as being
5573 able to handle gcc-produced code (which it now can).
5574 It also doesn't do frame caching (which is not useful
5575 more recent gdb versions).
5576 I also used my code for push_/pop_dummy, more or less.
5577 I tried to incorporate AF's code for testing sigtramp
5578 while backtracing; I probably got it wrong.
5579 Added mips_print_register, which tries to scrunch as much
5580 information as possible on a screen...
5581 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5582 under mips-pinsn.c), I don't see anything mips-specific here,
5583 and I don't see it being all that useful anyway.
5586 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5587 Use more register names (rather than hard-cases numbers).
5589 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5591 * Hack up 3.90.11 changes:
5593 * Makefile.dist (depend): parameterize $(GCC).
5594 Add solib.c and solib.o.
5595 (readline): Fix vpath for both absolute or relative SRCDIR.
5597 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5598 Also, let the part I didn't understand at least compile so
5599 I can test the rest. FIXME.
5601 * dbxread.c: Fix thinko using strcmp.
5602 (init_psymbol_list): declare static.
5603 (partial_symbol_file_open): Comment cleanups better, avoid
5604 cleaning up the string table since the caller will do that.
5605 Move the stat for mod time into symbol_file_command, temporarily.
5606 (There should be a mod time for each symbol file, eventually,
5607 to control its rereading. FIXME.)
5609 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5610 SunOS, which gives error for shared libs otherwise. (From
5611 Schaefer, probably FIXME needs work for portability.)
5613 * solib.c: Move #include "param.h" to work.
5614 Lowercase all the Uppercase Letters In the Messages.
5615 (find_solib): Clean up inferior_so_name for debug printouts.
5616 Allow no argument, to mean all shared libraries.
5618 * symmisc.c: include param.h to get CLEAR_SOLIB.
5620 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5622 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5623 to 3.90.11. ChangeLog entries below are from this.
5625 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5629 * Makefile.dist (HFILES): Add tm-sunos.h.
5631 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5635 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5637 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5639 * sparc-opcode.h Added single-operand version of rett.
5641 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5643 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5644 Put parens around gcc_p in expansion.
5646 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5648 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5650 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5652 * Changes for Sun shared libraries:
5653 blockframe.c (find_pc_partial_function): If a non-text symbol
5654 is found, set *address = pc - FUNCTION_START_OFFSET.
5655 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5656 Disable breakpoints instead of giving an error.
5657 source.c (select_source_symtab): Initialize cs_pst.
5658 symmisc.c: Call CLEAR_SOLIB if defined.
5659 symtab.h: Make text{low,high} CORE_ADDR not int.
5660 (psymtab): New field addr.
5662 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5663 (record_misc_function): Give correct type for N_DATA symbols.
5664 (condense_misc_bunches): do "misc_function_count = j" regardless
5666 Take code which is shared between symbol_file_command and
5667 add_file_command and put it into partial_symbol_file_{open,read}.
5668 Split add_file_command into add_file_command and add_file.
5669 Make psymtab_to_symtab read in the string table if the file
5671 Two new parameters to read_dbx_symtab and start_psymtab.
5672 tm-sunos.h: New file.
5674 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5676 * infcmd.c: Change cont_command to continue_command and "cont"
5679 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5681 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5683 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5685 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5686 size 1,2,4,8 rather than size < 8.
5688 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5689 as necessary, not just once.
5691 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5693 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5695 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5697 * tm-news.h: Add CALL_DUMMY_*.
5699 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5701 * config.gdb: In list_host, list_target, use ${i}, not $i.
5703 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5705 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5707 * sparc-opcode.h: Change all store floating-point state register
5708 instructions to have the right match & lose fields.
5710 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5712 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5714 config.gdb: If srcdir != ., create readline directory and
5715 copy a makefile into it.
5717 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5718 consistency with POSIX.
5720 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5721 when we exit its exp_valid_block.
5723 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5725 * Makefile.dist: Bump version to 3.91.3.
5727 * Clean up handling of breakpoint commands (somewhat).
5728 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5730 inferior.h: Add breakpoint_proceeded to inferior status struct
5731 and globals; save it and restore it.
5732 (clear_breakpoint_commands): Cleanup, remove old #define.
5734 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5735 (save_inferior_status, restore_inferior_status): handle it also.
5736 (proceed): Remove earlier code that set breakpoint_proceeded.
5737 It is now set only in clear_proceed_status.
5738 (clear_proceed_status): Cleanup, use bpstat_clear rather
5739 than clear_breakpoint_commands. No callers need the stop_bpstat
5740 between clear_proceed_status and proceed.
5742 infcmd.c: Add breakpoint_proceeded definition and comment.
5743 (cont_command, jump_command, signal_command): Move call to
5744 clear_proceed_status right next to call to proceed.
5746 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5747 caller's argument while running down the chain of breakpoints.
5748 Use new variable "breakpoint_proceeded" to determine when
5749 a command that it executes moves the inferior past the
5751 (bpstat_clear): Handle NULL argument.
5752 (bpstat_clear_actions): Avoid useless call to
5753 breakpoint_auto_delete.
5754 (delete_breakpoint): Clean up bpstat's that are pointing to
5755 the deleted breakpoint from the stop_bpstat chain.
5756 (breakpoint_auto_delete): Simplify.
5758 * Clean up handling of EOF, error on stdin, etc. This was
5759 prompted by a network problem that caused gdb to go into an
5760 infinite loop filling up its malloc'd memory.
5762 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5763 not clear_breakpoints_commands, which is now gone.
5764 (main): If command_loop returns (e.g. from EOF on stdin), do
5765 a quit_command (looping back to command_loop if quit_command
5766 doesn't really quit).
5767 (command_loop): check result from command_line_input and
5768 exit if it returns NULL, rather than passing the NULL to
5770 (gdb_readline): Free malloc'd result space before returning
5773 * utils.c (query): Handle C-d to mean "yes", just as if the
5774 input was not a terminal. Also avoid infinite loop if EOF
5775 occurs in mid-input-line before newline. This allows
5776 query to be used at EOF on stdin with reasonable results.
5778 * infrun.c (proceed): Set breakpoint_proceeded.
5780 * values.c (value_as_long): Avoid infinite recursion for enums.
5781 (_initialize_values): Fix typo in help msg (kingdon).
5783 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5784 RL_LIB for linking. This allows -lreadline for linking
5785 and nothing for dependencies, once readline is a real library.
5787 * config.gdb: Jim Kingdon: give useful error message if the
5788 host or target type is not recognized.
5790 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5791 it just defines it. Dumb, but deal with it.
5793 * Jim Kingdon suggests:
5794 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5796 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5798 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5800 * Clean up Bothner's changes.
5802 * blockframe.c (clear_pc_function_cache): New function.
5803 * blockframe.c: remake cache_pc_function_* static.
5804 * dbxread.c (symbol_file_command): remove references to
5805 cache_pc_function_* variables.
5806 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5807 * printcmd.c: Avoid kludging a global variable (addressprint)
5808 to avoid printing the address of a string twice. Instead,
5809 pass the format letter 's' down low enough that it can be seen
5810 to avoid this problem.
5811 (print_formatted): Pass format arg to value_print.
5812 (restore_addressprint): Remove function.
5813 (do_examine): Avoid hacking addressprint, cleanups and such.
5814 (print_frame_args): Add a comment to a Bothner change.
5815 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5816 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5817 to wipe out the values cached in blockframe.c.
5818 * symtab.c (find_method): Add comment saying how big you must
5819 allocate to be "big enough". Per being terse again.
5820 * valprint.c (val_print): Handle format letter "s" to print
5821 strings without addresses. Add comment to vtbl printing code
5822 which casts with wild abandon. Rearrange reference-printing
5824 @0xaddr: value (print w/addressprint)
5825 value (print w/~addressprint)
5826 @0xaddr (parameter lists w/addressprint)
5827 or nothing (parameter lists w/o addressprint)
5829 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5831 * Merge more changes from Per Bothner:
5833 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5834 annoying) that I tried to improve it. Here are my suggestions.
5836 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5839 Do automatic de-reference when taking the address of a reference.
5841 Don't deref_ref when printing parameter lists.
5843 More attempts at treating refernences properly.
5845 In val_print, if deref_ref==0, don't print dangling " = ".
5847 Add COERCE_REF macro, which de-references an REF.
5849 * Merge changes from Per Bothner:
5851 * Fixed (Sony news)-specific configuration problems.
5852 * Fixed other problems with using vanilla pcc and libc (enum problems;
5853 assumption that vsprintf exists).
5854 * Some major speed-ups (finc_pc_partial_function now caches a match;
5855 parsing avoids duplicate symbol_lookup calls).
5856 * Changed handling of baseclasses (no longer use baseclasses field
5857 of struct type, use the first n_baseclasses fields instead).
5858 * Various minor changes/fixes, most C++-related.
5861 Cache the most previous match from find_pc_partial_function.
5862 (Save both low and high ends of matching function's pc range.)
5863 This speeds up the loop of infrun.c:wait_for_inferior quite
5864 a bit, and makes step/next commands much zippier.
5866 Added an enum->int cast (otherwise, some compilers barf).
5868 No longer set baseclass offset to 0, since multiple
5869 inheritance now mostly works.
5870 Added a number of casts, to shut up compiler warnings
5871 (after stabs where made enums, not ints).
5872 When discarding a symbol table (in symbol_file_command),
5873 must clear the cache introduced in blockframe.c.
5874 Don't convert $vtbl_ptr_type to vtbl any more.
5875 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5876 Mask off sign bit emitted by g++ for virtual table offset.
5877 Set voffset to -1 (not 1) for static member functions.
5879 Changed parsing/lexing of names to avoid doing symbol lookup twice
5880 (once when lexing to determine symbol class, once for real).
5881 Now only call symbol_lookup once. Fields of 'this' win especially big.
5883 Subpress printing addr twice in the case of 'x/s addr'.
5885 lookup_basetype_type is no longer used.
5886 Add find_methods as recursive helper function to decode_line_1.
5887 This allows multiple inheritance to work.
5888 Also, once one or more matches has been found, do not look in
5889 base-classes. (Baseclass methods would be overridden, anyway.)
5891 Removed baseclasses array in struct type.
5892 Instead of using baseclasses[i], use fields[i-1].
5893 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5894 Changed sign convention of voffset (previous was inconsistent).
5896 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5898 Used to assume existence of vsprintf. Re-written to not need it
5899 if HAVE_VPRINTF is undefined.
5901 typecmp was too pessimistic. Made it less so.
5903 Don't print space after address.
5904 If vtable points to a misc symbol (with 0 offset), print it,
5905 since that indicates the actual class of the object.
5906 Changed ype_print_derivation_info to use new inheritance
5907 scheme (without baseclasses vector).
5909 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5910 Also, changes needed because TYPE_BASECLASSES were removed.
5912 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5914 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5917 If there is no path set, and the symbols don't indicate what directory
5918 a file was compiled in, look in the current directory. But either
5919 a path or a known compilation directory will prevent this.
5922 Three independent bug fixes:
5923 * Remove the #if 0 block that breaks some stuff.
5924 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5925 adapt gdb to either SunOS 4.0.* or 4.1.
5926 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5929 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5932 (type_print) Demangle the name being printed.
5933 (type_print_base) Handle botched demangling without coredump (tiemann).
5936 (check_stub_method): Document routine.
5937 (tiemann) fix bug for no-arg functions
5938 Avoid clobbering beyond end of malloc'd storage.
5939 Terminate the argument list properly.
5941 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5943 * Changes merged by John Gilmore:
5946 In breakpoint_1, use new print_address_symbolic instead
5947 of find_pc_partial_function. (This forces use of assembler-level
5948 addresses, and avoids misleading non-mangled source-level names.)
5950 Generalize ansi argument such that -1 means skip arglist totally.
5951 Removed global variable print_ansi_qualifiers (which made
5952 code non-reentrant), in favor of extra explicit arguments
5953 to internal routines.
5955 Add new helper function print_address_symbolic.
5956 Use find_pc_misc_function instead of find_pc_partial_function
5957 (since we want assembler-level symbols here).
5959 Print unknown function as just "f (...)", not "f (...) (...)".
5960 Use new fputs_demangled explicitly.
5962 Fixed a typing violation (problem: value.h cannot be imported
5963 without renaming many variable in this file).
5964 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5965 decode_line_1: Moved forward some never-reached code.
5966 Made decode_line_2 skip function prologues correctly.
5968 fputs_filtered should not demangle by default.
5969 Add new fputs_demangled to demangle on demand..
5971 Change value_struct_elt to use value_primitive_field (using recursive
5972 utility function search_struct_field). This allows foo.bar to work
5973 for multiple inheritance (so far only for data fields).
5974 Change check_field in the same way (recursive helper function
5975 to support multiple inheritance).
5976 (Note: there are more of these problems that I haven't fixed.
5977 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5978 value_of_this: 'this' symbol name is now just "this", note "$this".
5980 Don't print static members.
5981 Avoid printing "members of <type>" if there are none.
5982 Simplified type_print_derivation_info by merging duplicate code.
5983 Remove useless blank lines in type_print_base (ptype command).
5985 Added declaration of new routine value_primitive_field.
5987 Added value_primitive_field which is generalized version of
5988 value_field that can handle multiple inheritance (non-zero offsets etc).
5989 Re-implemented value_field to call value_primitive_field.
5991 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
5993 * infcmd.c -- insert else to avoid 'delete env' coredump when you
5994 delete the whole environment. Karl Berry reported the bug.
5995 * source.c - fix openp to avoid //'s in filenames, which
5996 trigger an Emacs bug causing it to not be able to find files
5997 when running gdb in a window.
5998 * dbxread.c - zap the #if 0 that botches the add-file code.
5999 It seems to work a lot better without all the code commented out.
6001 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
6003 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
6006 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
6008 * Makefile - added a ${CFLAGS} to a couple of entries,
6009 added remote-sa.sparc.c
6010 * added remote.sa-sparc.c, a modification of remote.c
6011 which conducts a dialog directly with the SparcStation prom.
6012 * breakpoint.c, infrun.c, sparcdep.c added
6013 remote_insert_breakpoint(), and remote_remove_breakpoint()
6014 to breakpoint.c instead of directly writing breakpoint instructions.
6015 * sparcdep.c on remote_debugging,there is no need
6016 to remove signle step breakpoint instructions.
6017 * main.c added "-epoch" flag and "int epoch_interface" to main.c
6019 * printcmd.c - epoch interface sends lisp expressions to open up
6020 epoch windows on inspection.
6021 * valprint.c - added arrayprint, and addressprint and made adding
6022 format controls easier
6023 * wait.h added a couple of undef's because we were getting
6024 complaints about WSTOPSIG and WTERMSIG begin redefined.

6094 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
6095 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
6096 when printing the type.

6120 step_resume_break_address != NULL, even if another_trap.
6121 If trap_expected and we enter sigtramp, then set up a
