28 * elfread.c: Re-enable compilation of register_addr() stub
29 whenever it is not supplied by coredep.c
31 Sat Nov 9 00:40:32 1991 John Gilmore (gnu at cygnus.com)
33 Add tracking of object files (that contain symbols) to gdb.
34 This includes a "struct objfile" that owns symtabs and psymtabs
35 that were read in from that binary file.
37 * symfile.h: Add struct objfile. Add pointer to the objfile
38 into the struct sym_fns.
39 Replace global `symfile' and `symfile_mtime' with
40 `symfile_objfile'. Add global object_files chain.
42 * symfile.c: Move param.h above symtab.h.
43 (sort_misc_function_vector): Add.
44 (syms_from_objfile): Was syms_from_bfd.
45 (symfile_open): Now returns objfile.

54 * dbxread.c: Make more errors into complaints.
55 (push_subfile, pop_subfile): Move to buildsym.c.
56 (dbx_symfile_read, dbx_symfile_init, fill_symbuf, read_dbx_symtab,
57 start_psymtab, psymtab_to_symtab_1, read_ofile_symtab,
58 dbx_psymtab_to_symtab, ): Use bfd ops, don't use file descriptor.
59 Pass objfile. Change callers.
60 (fill_symbuf, SWAP_SYMBOL): Take bfd as arg.
61 (read_dbx_symtab): Just wipe out new symbols, not all, on error.

67 * buildsym.c (end_symtab): Pass objfile.
68 (dbx_lookup_type): Handle null typevector.
69 (dbx_alloc_type): Check file number, not sym number, for -1.
70 (find_symbol_in_list): Add for xcoffread.
71 (start_symtab): Default typevector is empty. Keep reusing same
73 (end_symtab): Take objfile argument and pass it to
74 allocate_symtab. Don't make a symtab if no blocks or symbols.
75 Handle empty typevector.
76 (push_context): New function for context stack nesting.
77 (read_type): Mark FIXME where we need to reintroduce type smashing.
79 * buildsym.h (pop_context): Macro, paired with push_context.

91 and use objfile argument.
92 (psymtab_to_symtab_1, read_ofile_symtab): Don't take or use file
93 descriptor. Use BFD internal functions instead.
94 (end_symtab): Call global allocate_symtab.

100 (struct partial_symtab): Add objfile * and objfile_chain * of
101 psymtabs. Remove symfile_name.

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

485 * inflow.c: Handle TIOCGLTC_BROKEN for Amiga.
488 * values.c (show_convenience): Use printf_filtered.

491 (echo_command): Use printf_filtered, and force output out.
493 * dbxread.c (read_enum_type): Avoid Modula-2 kludge that breaks C
495 * i387-tdep.c (double_to_i387): Fix typo for double_to_ieee_extended.
496 * utils.c (_initialize_utils): If !ISATTY, don't paginate.
497 * configure.in, tconfig/decstation, xconfig/decstation: Rename
498 dec3100 to decstation.
500 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)
502 * doc/gdb.texinfo: Catch up to changes recorded here in ChangeLog
503 (nodes Continuing and Stepping; Memory; Targets) clarifications
506 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
508 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move
509 REGISTER_U_ADDR to corresponding xm- file. Sugg. by Peter Schauer.
511 * symmisc.c (print_partial_symtabs): Add printpsyms debug cmd.
513 * m68k-tdep.c (m68k_push_dummy_frame, m68k_pop_frame): Add
514 generic routines for calling inferior functions.
516 * blockframe.c (inside_main_scope, inside_entry_scope): New.
518 * copying.awk: Filter formfeeds out of copying & warrantee.
519 Make them available as `show copying' and `show warrantee' also.
520 * main.c (print_gnu_advertisement): Advt `show' commands.
522 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)
524 * mach386-xdep.c: Even when cross-compiling, leave in the
525 core-file reading code.
526 * core.c (get_core_registers): Avoid coredump if no .reg section.
528 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
530 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
531 This avoids coredumps under `set print object on' in value_headof
532 (called erroneously by value_from_vtable_info) for `p &struct'
533 or `p *struct'. From Peter Schauer.
535 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
537 * Makefile.in: Roll version to 4.1.2.
538 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
539 size from BFD (but, FIXME, we don't yet read external nlists's and
540 convert them to internal nlists's before handling them -- we still
541 assume they have the same size and alignment.) Use SET_NAMESTRING
543 * exec.c (exec_file_command): Move dead coff-encapsulation code
545 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.

549 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
550 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
552 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
554 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
555 * mips-xdep.c (store_inferior_registers): Don't try to
556 write the (pseudo) FP.
557 * mipsread.c (parse_partial_symbols): Improved algorithm for
558 setting pst->texthigh.
560 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
562 * doc/Makefile: make TEXINPUTS include . everywhere
564 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
566 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
567 vestiges of typevectors, which were for symsegs and are no longer
568 used. (From a question by Eliot Dresselhaus
569 <dresselh@RFT30.nas.nasa.gov>).
571 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
573 * dbxread.c, coffread.c: static-ize functions that were
574 gratuitiously external. (From Fred Fish.)
576 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
578 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
579 until it is large enough.
581 * dbxread.c (read_type): Handle error case slightly better.
582 Make complaint message not C++-specific.
584 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
586 * infrun.c (wait_for_inferior): Fix step/next so that you only
587 stop at the beginning of a new line. This fixes various problems
588 with for loops, nested if-else's and switch statements.
590 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
592 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
593 between symtabs and psymtabs become ordinary error()s.
595 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
596 properly, making "end pc" correct in shared lib psymtabs.
597 (From Guy Harris <guy@auspex.com>.)
599 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
601 * dbxread.c: Enable, but soften, const_vol_complaint.
602 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
603 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
604 should be file-scope, not global.
605 (read_struct_type): Remove ancient multiple-inheritance warning.
606 (read_range_type): Check base type, complain & patch if undefined.
607 * stack.c (frame_info): Demangle the function name in `info stack'.
610 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
612 * eval.c (evaluate_subexp_for_address): Don't use
613 TYPE_POINTER_TYPE directly (it might be zero if this type has
614 never had a pointer created before); use lookup_pointer_type.
615 * symtab.c (lookup_method_type): Arguments were swapped in all
616 callers, so fix it here. I'm amazed this worked at all!
618 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
620 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
621 "bss" rather than "data" symbols, but which still conflict.
624 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
625 * core.c (core_files_info): Shorten output.
626 * exec.c (exec_files_info): Ditto.
627 (build_section_table): Ignore zero-length sections.
628 * language.c, printcmd.c: Lint.
629 * language.h (get_frame_language): Declare.
630 * saber.suppress: update.
631 * stack.c (find_relative_frame): Remove complex code that was
632 #if 0'd, stick with simple code. Lint.
633 * saber.suppress: Update a bit.
634 * symfile.c (add_symbol_file_command): Add "?" to question.
635 * utils.c (parse_escape): Avoid \a due to bdead compilers.
636 * value.h: Declare typedef_print.
638 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
641 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
642 (Reported by Mark Peek <mark@imagen.com>.)
644 * solib.c (solib_map_sections): Relocate all sections, even
645 though only the text section's size is tracked. Mark ld_text
646 for eventual elimination as we generalize to N sections.
648 * infrun.c (wait_for_inferior): Don't check if the PC is in a
649 call_dummy if we were stopped by a random signal that is being
650 passed to the program. This produced wierd results when calling
651 functions in the inferior and signals (e.g. SIGALRM) were in use.
653 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
655 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
656 Bugfix from Paul Eggert <eggert@twinsun.com>.
657 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
658 * valprint.c (print_floating): Print 9 digits for IEEE floats.

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

874 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
876 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
877 entries are enclosed herein. Not all of these changes
878 have been merged into the master GDB sources -- check the
879 ChangeLog above here for the merge log.
881 Mon Jun 3 17:05:45 EDT 1991
883 m2-exp.y Created. Tested outside of GDB for a few days. Proper
884 operators were added, C specific operators and tokens
885 removed. yylex() revamped to some extent. Still things
886 missing from the grammar, such as sets.
887 Tested for two weeks in GDB v3.5.
889 Tue Jun 11 17:23:48 EDT 1991
891 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
892 so they are built-in. Sort of a hack.
894 Fri Jun 14 12:53:51 EDT 1991
896 m2-exp.y Added range checking for numeric constants. Any numeric
897 constant is assumed to be of builtin type INTEGER unless:
898 (1) it is octal or hexadecimal, in which case it is a
899 CARDINAL; (2) it is too big to fit into an INTEGER, in
900 which case it is a CARDINAL.
901 eval.c Added simple range checking for +, -, and * on integers.
902 Doesn't work very well for *, since 6 * 1,000,000,000 =
903 1,705,032,704, which fails the simple test of result >=
904 first_operand, no matter in what order the operands are.
906 Tue Jun 18 14:11:30 EDT 1991
908 Broke the parser into parts, one containing the C grammar and the other
909 containing code to be shared by all of the grammars.
911 The following files no longer exist:
916 The following files were added:
918 c-exp.y (The C grammar)
919 m2-exp.y (The Modula-2 grammar)
920 parser-code.c (Code that is shared by the above grammar)
924 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
925 now necessary to use the Bison compiler compiler, since it
926 will generate function/variable prefixes other than yy.
928 Tue Jun 18 16:47:49 EDT 1991
930 symtab.[ch] Added the external variable working_lang, than holds the
931 value of the current working language.
932 Added the ennumerated type language_mode, with the values
933 language_auto and language_manual, the former meaning that
934 GDB sets working_lang as needed, and the latter meaning
935 that the value of working_lang is totally under user
937 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
938 REAL, BOOLEAN and CHAR. Also added the type codes
939 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
940 utils.c Added set_language_command and show_language_command to
941 implement the GDB support commands "set language" and
943 expression.h A number of identifiers were added to the type exp_opcode
944 to facilitate Modula-2 builtin functions, integer
945 division, and array indexing.
947 Wed Jun 19 13:25:58 EDT 1991
949 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
950 if the language specified by working_lang requires the use
951 of strict typing of expressions. Eventually, even this
952 will be able to be changed by the user.
953 Added the macro RANGE_CHECK, which evaluates to non-zero
954 if the language specified by working_lang requires the
955 checking of a value against the domain of its type.
956 Eventually, even this will be able to be changed by the
958 language.[ch] Predicates involving types (simple_type, ordered_type,
959 same_type, integral_type, numeric_type, character_type,
960 boolean_type, float_type) are added. These predicates are
961 based on the current value of working_lang, and are handy
964 Wed Jun 19 15:39:34 EDT 1991
966 eval.c Added the function type_array_rank which computes the rank
968 valarith.c Added the funtion value_bool, which when given a integer
969 value.h value (ie. struct value *) as an argument, it returns a
970 boolean value (ie. struct value *) true if that integer
971 is non-zero, and a boolean value false otherwise.
972 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
973 will print out properly.
975 Wed Jun 19 16:36:34 EDT 1991
977 valops.c Added the function value_capitalize, which returns it
978 value.h argument capitalized if its argument is a lowercase
979 letter, or the argument unchanged if its argument is not a
981 valarith.c Added the function range_check_p, which returns non-zero
982 value.h if its value argument is between the integral bounds upper
984 Added the function range_check_enum_p, which makes sure
985 that its value argument is a valid member of the domain of
987 Added the function range_check_range_p, which makes sure
988 its value argument lies between the upper and lower bounds
989 of its type argument, which must be a ranged type.
990 Added the function check_array_index, which range and type
991 checks an index of an array.
992 Added the function value_multi_subscript, which computes
993 array[idx1,idx2...idxN], given a value array and an array
994 of values representing indicies.
995 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
996 unpack_long to work with TYPE_CODE_BOOL and
999 Wed Jun 19 18:04:08 EDT 1991
1001 symtab.c Stored pervasive types in a structure and make
1002 lookup_pervasive_type() a lookup function that was based
1003 on working_lang. If lookup_pervasive_type() returned
1004 non-zero, then that value was returned (a fix, since
1005 before it simply wouldn't return the pervasive type.)
1006 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
1007 non-zero if the language specified by working_lang means
1008 "conversion" when it says "cast".
1009 valops.c Added the function value_real_cast(), which performs a
1010 value.h *cast*, not a *conversion*, which is what value_cast()
1011 does when it can. In particular,
1012 value_cast(<float_type>,4) = 4.0, while
1013 value_real_cast(<float_type>,4) = some mess.
1014 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
1015 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
1016 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
1017 and MIN on integral types. *NOTE*: These are currently
1018 hardcoded to work only if there are 8 bits per storage
1020 eval.c Made logical functions call value_bool to return a
1021 properly typed boolean value, based on working_lang.
1023 Thu Jun 20 11:55:27 EDT 1991
1025 valprint.c Types now print out in a Modula-2 fashion. This works for
1026 the cases when the type is printed out step-by-step, that
1027 is, it doesn't work when the name of a structured type
1028 (which includes the keyword "struct", etc.) is simply
1030 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
1031 since type specifications in C and Modula-2 are very
1032 different. The C printing of a type is very recursive,
1033 whereas in Modula-2 it is generally very simple. C has
1034 type prefixes and suffixes, which have no real analogue in
1035 Modula-2. Maybe type_print() should call a language
1036 specific type printer. This is also advantageous if we
1037 compile GDB to exclude some of the languages. We'll just
1038 leave those functions out.
1040 Thu Jun 20 16:57:10 EDT 1991
1042 dbxread.c When reading the complete symbol table in (via
1043 psymtab_to_symtab()), the number and types of function
1044 arguments are added to a function type. define_symbol()
1045 calls add_param_to_type() to accomplish this.
1046 Assumption: when we come across a function definition
1047 (N_FUN symbol with an 'f' or 'F' in the name), its
1048 arguments will appear before another function definition.
1049 When a function is found, a pointer to its type is placed
1050 in the global in_function_type. Changes that
1051 add_param_to_type() makes are to this global.
1052 valprint.c The type of a function now includes (for Modula-2) the
1053 types of its parameters.
1054 eval.c Type checking and a check for the proper number of
1055 arguments is now done for function calls. Not sure of the
1056 impact this has on C++ member function yet.
1058 Thu Jun 20 19:58:48 EDT 1991
1060 valprint.c Rewrote the type printer. Broke it into two language
1061 specific parts, adding the functions type_print_m2() and
1063 An unfortunate consequence is this: if you debugging a C
1064 program in Modula-2 mode (why?), info types does not work
1065 well with regular expressions, since the types are printed
1066 out in Modula-2 terminology, but stored in C terminology.
1067 language.[ch] Added the functions new_type_last(), type_keyword(), and
1068 type_sep() to aid in the printing of typedefs.
1069 symtab.c Made the printing of typedefs as language independent as
1070 possible through calls to new_type_last(), type_keyword(),
1073 Fri Jun 21 11:50:26 EDT 1991
1075 dbxread.c Check all incoming ennumerated types. If it looks like
1076 Modula-2's BOOLEAN type, then change the type_code of the
1077 type to TYPE_CODE_BOOL so we can process it as a boolean
1079 valprint.c Replaced some of the 0x%x with calls to sprintf and
1080 hexformat() in val_print().
1081 language.[ch] Added the function hex_to_string(), which converts its
1082 integral argument to a hexadecimal number (format is
1083 language based) and returns the result as a string.
1085 Mon Jun 24 12:25:07 EDT 1991
1087 valprint.c Some functions call type_print_1() directly, instead of
1088 value.h using type_print(), so they can specify where (column) to
1089 print things. Since type_print() takes care of language
1090 dependence, that needs to be called first. Added a
1091 parameter depth to type_print() (so it is now like
1092 type_print_1). Changed type_print to type_print_at, and
1093 made type_print a macro that passes a depth argument of
1095 symmisc.c Changed all calls to type_print_1 to calls to
1097 Makefile.dist Made it possible to build GDB for a specific set of
1098 depend languages. Do this by passing a definition for the macro
1099 LANGS to make. LANGS should be a string containing a
1100 space-separated list of language names (ie. LANGS="c m2").
1101 The default is to build all languages. Note that grammar
1102 files must follow the naming convention of <lang>-exp.y.
1103 gdb.lang This holds the current value of the LANGS macro. It is
1104 examined every time make is called, and is updated if
1106 eval.c Added #ifdef _LANG_<lang> to these files.
1107 expread.c Still need to add them to dbxread.c and coffread.c.
1115 Mon Jun 24 16:33:11 EDT 1991
1117 language.[ch] Added the functions hexformat_pre() and
1118 hex_to_string_pre(), which take a prefix argument to
1119 include in the format string. Thus, hexformat_pre("08") will
1120 return "0x08x" (if the working language is language_c).
1121 Made hexformat() and hex_to_string() calls to the above
1122 with "" as the prefix argument.
1124 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
1125 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
1126 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
1127 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
1128 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
1129 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
1130 valprint.c, vax-pinsn.c
1132 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
1133 calls to hexformat() and hex_to_string(). Format strings without
1134 the leading "0x" were ignored.
1136 depend Updated to take the above into account.
1139 Tue Jun 25 15:27:18 EDT 1991
1141 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
1142 and type_check_t to keep track of the current state of
1143 range and type checking.
1144 main.c Added the variables range_mode, range_check, type_mode,
1145 and type_check to record the current state of range and
1146 type checking. Added initialization code to main().
1147 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
1148 the above variables.
1151 Tue Jun 25 17:57:08 EDT 1991
1153 dbxread.c process_one_symbol() updates the variable (enum language)
1154 source_lang based on the extension of the filename
1155 contained in the N_SO sybmol that started this symtab.
1156 When end_symtab() is called, the value of source_lang is
1157 put into the language field.
1158 stack.c select_frame() sets working_lang (and possibly type_check
1159 and range_check) to the language field of the symtab
1160 associated with the frame that is selected if working_mode
1161 is language_auto. If working_mode is language_manual, a
1162 warning is printed and working_lang is not set.
1163 language.c Added the function set_type_range(), which sets the value of
1164 type_check and range_check (if their modes call for
1165 automatic setting) based on the current value of
1166 working_lang. A non-zero argument will cause the current
1167 settings to be output.
1170 Wed Jun 26 14:51:40 EDT 1991
1172 eval.c Added range checks on assignment.
1173 m2-exp.y Added the grammar for sets to the language. Currently,
1174 these do not do anything except print an error message.
1176 Wed Jun 26 17:01:04 EDT 1991
1178 m2-exp.y Added the ability for parse_number() to parse negative
1179 numbers. A global flag is set upon encountering a unary
1180 minus. This was done to make, for example, 1 parse as a
1181 CARDINAL, and not as an integer, per Wirth's examples in
1182 Programming in Modula-2 ed.4.
1183 valprint.c Added support for "set radix 2" by then setting
1184 output_format to 't'.
1185 eval.c Implemented range checking on subrange types. Added calls
1186 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
1187 Implemented MIN and MAX for ennumerated types. The
1188 minimum value of an ennumerated type is defined by Wirth
1189 as the first identifier, and the maximum as the last.
1190 m2-exp.y Made octal numbers ending with "B" be characters and those
1191 ending with "C" be numbers, per Wirth's book. (p. 34)
1193 Thu Jun 27 14:11:52 EDT 1991
1195 stack.c select_frame() now only sets working_lang, it does not
1196 notify the user. If working_mode is language_manual, then
1197 a warning is issued once.
1198 main.c At the end of each call to execute_command(), working_lang
1199 is checked against the local static (enum language)
1200 current. If they differ and working_mode is
1201 language_auto, the new settings of language, type and
1202 range checking are printed out.
1203 stack.c Modified frame_info() to include the language of the
1204 current frame in the output of "info frame".
1205 language.[ch] Added the function language_str() which returns the name
1206 of the current language.
1208 Fri Jun 28 15:33:14 EDT 1991
1210 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
1211 the language. INCL and DECL currently cause an error,
1212 since sets are not implemented yet. INC and DEC are
1213 implemented as PREINCREMENT/PREDECREMENT with one
1214 argument, and as ASSIGN_MODIFY with two arguments.
1215 eval.c Added type checking to the above cases.
1216 value.h Added not_lval_constant to the lval_type ennumerated type.
1217 not_lval_constant means that the value is a constant
1218 value; that is 3 or 'a' or TRUE, not as in a constant
1219 identifier. This is used to help coerce numbers such as 3
1220 to either signed or unsigned numbers.
1221 valops.c Added the function value_coerce_constants() which coerces
1222 constant integers as following: if one is a constant and
1223 the other is not, the constant's type is set to the type
1224 of the other argument. If both are constants and one is
1225 signed, the other is converted to a signed constant.
1227 Sat Jun 29 17:26:29 EDT 1991
1229 valarith.c Added a better range checker. It now checks range
1230 (successfully) on integral operations [+-] (signed and
1231 unsigned) for any C sized type. Still does not work well
1232 for multiplication.)
1233 int_in_size() returns an integer that is coerced to fit into
1234 specified number of bytes.
1236 Mon Jul 1 13:04:14 EDT 1991
1238 language.[ch] Added the function binop_result_type(), which returns the
1239 builtin (struct type *) type that would be the result of a
1240 binop on the two values V1 and V2.
1242 Wed Jul 3 19:22:53 EDT 1991
1244 source.c Extended source_info() to include the source language in
1245 the output from "info source".
1247 Fri Jul 5 13:48:52 EDT 1991
1249 utils.c Moved the support functions for the GDB set/show commands
1250 dealing with language into language.c.
1251 language.c Added the function language_info(), which displays info
1252 about the current working language, type and range check
1253 settings. Called via the GDB command "info language".
1254 Added an initialization routine _initialize_language(),
1255 that sets defaults for the language, type and range
1256 variables and sets up the new GDB commands.
1257 main.c Language setup moved to language.c.
1260 Mon Jul 8 10:10:22 EDT 1991
1262 valarith.c Debugged the range checker for arithmetic. Still does not
1263 work for multiplication very well.
1265 Mon Jul 8 12:40:37 EDT 1991
1267 language.[ch] Added the function value_true() which returns non-zero if
1268 its argument represents a boolean true value.
1269 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1270 check the truth of an expression.
1272 Thu Jul 11 12:51:34 EDT 1991
1274 language.[ch] Added the predicate structured_type(), which returns
1275 non-zero if the argument is a structured type.
1276 Added the predicate pointer_type(), which returns non-zero
1277 if the argument is a pointer type.
1278 eval.c Added the ability to do addition and substraction on
1279 pointers and integers. This case simply bypasses the
1282 Thu Jul 11 14:41:42 EDT 1991
1285 Added the symbol N_DEFD (0x4a) which is a definition
1286 module dependency that is used by the GNU Modula-2
1287 compiler and the linker. It is not important to GDB,
1288 except that [dbx|coff|mips]read.c should ignore these
1291 Fri Jul 12 16:07:00 EDT 1991
1293 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1294 0 in val_print(). Also added statements to the else part
1295 to coerce type (argument to val_print) to a pointer type
1296 if it is an "array of unspecified length".
1297 valops.c Added the function value_m2_string(), which returns a
1298 (value) value which is a constant string, whose type is
1299 (ARRAY [0..n] OF CHAR). The length field of the type
1300 structure is set to zero, so it will be interpreted as an
1301 "array of unspecified length".
1302 stack.c Moved the language/frame mismatch check to
1303 main.c:execute_command().
1304 main.c The working language is recorded each time
1305 execute_command() is executed. If working lang has
1306 changed during its execution, then the new
1307 language/type/range info is printed out for the user. If
1308 the working language does not match the language of the
1309 frame, a warning is issued.
1311 Sat Jul 13 16:16:39 EDT 1991
1313 eval.c Moved all the type-checking stuff for operators to
1314 language.[ch] language.c. This is so we can keep language-specific
1315 stuff (like for what type operators are defined) in
1317 language.[ch] Added the function binop_type_check(), which checks to see
1318 if its two (value) arguments are type-compatible with its
1319 opcode argument. The opcode should represent an operation
1320 involving an operator. Also added the macro function
1321 unop_type_check, which calls binop_type_check with a
1322 NULL second argument.
1323 expprint.c Added Modula-2 operators to the op_print_tab, so info
1324 expression.h break works correctly. Also added "op_string", which
1325 returns the string corresponding to the (enum exp_opcode)
1326 opcode that is its argument.
1329 Sat Jul 13 18:26:18 EDT 1991
1331 coffread.c Added code to record the type of function arguments with
1332 each paricular function. Code is very similar to that
1334 dbxread.c Moved add_param_to_type() to symtab.c
1335 symtab.[ch] Added function add_param_to_type() from dbxread.c
1337 *** NOTE: The above additions have not been tested.
1339 Mon Jul 15 12:50:47 EDT 1991
1341 langauge.[ch] Added the functions type_error and range_error, which work
1342 like error() except if the type/range mode is set to
1343 *_mode_warn, then they do not do a return_to_top_level(),
1344 but merely print a warning.
1345 Also changed [set|show]_[type|range]_command() to support
1346 the new "warn" feature.
1348 Thu Jul 18 17:50:54 EDT 1991
1350 mipsread.c Added code to record the type of function arguments with
1351 each particular function. Code is very similar to that
1354 *** NOTE: The above additions have not been tested.
1356 Fri Jul 19 11:19:10 EDT 1991
1358 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1359 UMIN_OF_SIZE, which when given a size of a numeric type,
1360 return the maximum and minimum value it can hold. UMAX...
1361 and UMIN... return the result for unsigned types.
1362 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1363 struct types. They call above macros.
1364 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1365 avoid a name conlict with the above.
1366 c-exp.y Added range checking on numeric constants in
1367 parse_number() for completeness.
1368 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1369 return 0 if working_lang is not language_c.
1371 Thu Aug 8 14:17:22 EDT 1991
1375 breakpoint.c Documentation strings of some commands changed to
1376 eliminate the references to the C language where
1379 Tue Aug 13 15:48:03 EDT 1991
1381 m2-exp.y Added qualified identifiers to the grammar. The semantics
1382 are slightly different from those of the GDB operator ::
1384 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1385 type_exp, where type_exp is any valid type expression.
1387 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1388 printcmd.c Modified ptype_command() so it actually parses the input
1389 (necessary for type expressions with scope qualifiers).
1390 Added the function ptype_eval() which expects an
1391 expression composed of one OP_TYPE element.
1392 *.[ch] Replaced all occurences of parse_c_expression with
1394 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1396 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1398 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1400 Small fixes from Peter Schauer:
1402 * infrun.c (child_attach): Lint.
1403 * solib.c (find_solib): Handle shared libs version 2.
1405 Small fixes from David Wood:
1407 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1411 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1412 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1414 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1415 chars_per_line is at maximum (user typed `set width 0'). Fix
1416 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1418 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1420 * coredep.c: include ptrace.h where necessary.
1421 * mipsread.c(parse_lines): fix unsigned char problem that was
1422 messing up line numbers on SGI's and possibly other MIPS based
1424 * infrun.c (child_create_inferior): use better test to check
1425 return val from setpgrp().
1426 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1427 for sgi/irix support.
1429 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1431 * mipsread.c (parse_symbol): Put non-static procedures
1432 in the global block.
1434 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1436 Patch together `text_start' and `text_end' for 29K port.
1438 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1439 variables and set them based on the exec file.
1440 * am29k-tdep.c: declare text_start.
1441 * valops.c (call_function_by_hand): declare text_end.
1443 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1444 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1445 because machines that do this will also have to know to
1446 set NEED_TEXT_START_END. Besides, it was a redundant way to
1448 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1449 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1450 NEED_TEXT_START_END.
1452 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1454 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1456 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1457 Pass MUNCH_DEFINE to munch whenever we run it.
1458 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1459 format string; use 0x%x instead.
1460 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1461 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1462 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1463 * inflow.c: Handle `short' process group IDs.
1464 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,

1467 (coff_symfile_init): Initialize text_bfd_scnum.
1468 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1469 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1470 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1471 Merge target arm case with other "easy" cases. Add target
1472 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1473 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1475 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1476 * munch: Cope with RT/PC putting fns in data segment.
1477 Restore ability to override `nm' by specifying MUNCH_NM.
1478 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1479 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1480 and remote-adapt. Remove encapsulated coff #define's (the
1481 support should go in BFD, and gdb shouldn't know or care).
1482 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1483 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1484 * tm-29k.h: Update BADMAG (though it should go away).
1485 Allow the register definitions to be overridden in another
1486 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1487 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1488 DUMMY_SAVE_GR96, for handling kernel calling conventions
1489 that use GR64+ rather than GR96+.
1490 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1491 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1492 overrides various things.
1494 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1495 child_attach does, making a clean stop in the newly attached
1497 * remote-eb.c: Lint.
1499 * coffread.c: Make coffread independent of any particular
1500 variant of COFF. Avoid #include-ing any particular one except
1501 internalcoff.h. BFD now passes key values for symbol reading
1502 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1503 and the symbol masks and shifts); use them.
1504 Remove obsolete end_of_text_addr.
1506 * exec.c: Remove unused include files.
1508 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1510 * Makefile.in (documentation targets): Pass $(M4).
1511 Bugfix from eggert@twinsun.com (Paul Eggert).
1513 * stack.c (down_silently_command): Check for stack existence.
1515 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1517 * Makefile.in (VERSION): Update to 4.0.3.
1519 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1521 * core.c (core_file_command): Print frame at coredump with
1522 its level number, by calling print_stack_frame.
1523 * frame.h: Add selected_frame_level, print_stack_frame.
1524 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1525 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1526 Change print_sel_frame and print_selected_frame callers to
1529 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1530 * symfile.c (free_named_symtabs): Ditto.
1531 * main.c (main): wrap_here needs an arg.
1532 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1533 (solib_add): Avoid noise.
1534 (solib_create_inferior_hook): Lint.
1535 (sharedlibrary_command): Move dont_repeat to here.
1536 * utils.c (error): Call wrap_here to force buffered output.
1538 Small patches from Peter Schauer:
1540 * coffread.c (start_symtab): Free any existing line_vector before
1542 (read_coff_symtab): Ditto for type_vector.
1544 * source.c (lines_to_list): New variable, replacing function.
1545 (all uses): Use as variable.
1546 (_initialize_source): Add 'set listsize' and 'show listsize'.
1547 * utils.c (lines_to_list): Remove function.
1548 * stack.c (print_frame_info): Use as variable.
1549 * defs.h (lines_to_list): Remove declaration.
1551 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1553 * breakpoint.c (insert_breakpoints): Restore warning about
1554 the program might be running in another process, but only for
1555 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1556 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1558 * utils.c (error): if error_pre_print is set, print the string
1560 * main.c (main, print_gnu_advertisement, print_gdb_version):
1561 Reformat legalese so it always prints, but acts as an "I'm here"
1562 message while symbols are being read. If any errors occur,
1563 print a few newlines to set off the message and start it at the
1564 left margin. Remove mention of "help" command, and don't yak
1565 about symbol reading.
1566 (catch_errors): Error string is now printed first in case of
1568 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1569 suggest the "help" command.
1571 * Makefile.in (VERSION): Set to 4.0.2.
1573 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1575 * .gdbinit: Remove useless "rr" command. Set complaints
1576 to 1 for people debugging gdb.
1578 * breakpoint.c, remote-vx.c: Reword strings printed by
1579 catch_errors callers.
1581 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1583 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1584 (Fix from kenc@viewlogic.com.)
1586 Fix some infrastructure to be able to cope with host and target
1587 machines with different sized basic types (ints, ptrs, etc).
1588 (Idea from pierre@la.tce.com (Pierre Willard).)
1590 * values.c (value_from_longest): Rename from value_from_long.
1591 Handle pointer types as well as integers, so that targets with
1592 different pointer sizes from the host can be accomodated.
1593 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1594 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1595 uses of value_from_long to value_from_longest.
1596 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1597 the correct pointer type to value_from_long{est}.
1599 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1601 * remote-vx.c: Remove obsolete code for calling functions via
1602 vxworks kludge interface (it referenced value_from_long).
1604 * valops.c (value_string): Find malloc with lookup_misc_func, not
1607 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1609 Make writing to files work properly. (Fixes to BFD are also needed.)
1611 * core.c (core_open): Open file ourselves, read or r/w, depending on
1612 write_files. Use bfd_fdopenr.
1613 * gdbcore.h (write_files): New variable.
1614 * exec.c (write_files): Define variable, add set&show for it.
1615 (exec_file_command): Use write_files to open for read or r/write.
1617 Make shared library reading happen automatically. These changes
1618 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1620 * inferior.h (stop_soon_quietly): Add to exported variables.
1621 * infrun.c (child_create_inferior): call solib hook, if defined.
1622 (child_attach): call solib hook, if defined.
1623 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1624 (find_solib): Use lookup_misc_func rather than hand-rolled.
1625 (symbol_add_stub): New stub for catch_errors.
1626 (solib_add): Avoid output if !from_tty. Catch errors rather
1627 than just calling symbol_file_add and bombing.
1628 (solib_create_inferior_hook): Interface with the target process
1629 to let it read and alloc shared libs, then figure out what it did.
1631 * core.c (validate_files): Fix typo, soften warning.
1632 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1634 * utils.c (fputs_demangled): Avoid duplicate printing if
1635 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1637 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1638 (Fix from pierre@la.tce.com (Pierre Willard).)
1640 * main.c (catch_errors): Change argument to a char * from an int,
1641 since a char * can point to a struct full of glop, but an int
1642 is not guaranteed to be able to hold a pointer.
1643 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1644 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1645 * core.c (core_open, solib_add_stub): Adapt.
1646 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1648 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1650 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1651 by adding .NOEXPORT target.
1653 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1657 * Makefile.in (VERSION): Roll to 4.0.
1658 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1660 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1662 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1665 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1668 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1670 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1671 reflect above name change
1673 * WHATS.NEW: correct pointer to refcard.
1675 * doc/gdb.texinfo: update New Features, Installing
1677 * doc/gdbint.texinfo: add short description of configure +template
1679 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1681 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1683 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1685 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1686 tar file, add dependencies for referenced doc files.
1688 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1690 * coffread.c, symfile.c, stack.c: saberized.
1692 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1694 * doc/refcard.tex: permuted Essential Commands sec
1696 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1698 set/show symbol-reloading
1699 default set complaints 0
1701 RET-repeat disabled after prompted long displays
1702 processID (attach) interpretation of 2nd GDB cmdline arg
1704 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1706 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1707 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1708 breakpoint.c, main.c: lint.
1710 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1712 Install new configuration scheme for GDB and friends.
1714 * config.sub: Translate ordinary names to three-part names.
1715 * configure: Use three-part names internally.
1716 * configure.in: Translate three-part names to filenames.
1718 * README, WHATS.NEW: Update for gdb-4.0.
1719 * Makefile.in: Roll VERSION to 3.99.
1721 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1723 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1724 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1725 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1726 to single structures rather than arrays; when passing
1727 their address, use &. This avoids trouble with bdead compilers.
1728 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1729 instead. This avoids portability headaches.
1730 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1732 * source.c (open_source_file): Avoid ANSI const bdeath by
1733 skipping declaration and then casting result value.
1734 * tm-hp300bsd.h: Clarify comment.
1735 * utils.c (strstr): Result is const char *; ANSI bdeath.
1736 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1737 since system include file defines it differently from "defs.h",
1738 though the two are equivalent for our purposes.
1739 * tconfig/hp300bsd: Add m68k-tdep.o.
1741 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1743 * tconfig/sun*4: Remove warnings about system assembler.
1745 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1747 * mcheck.c: Avoid warning about undeclared abort fn.
1748 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1749 it causes recursive calls to error() when used in cleanups.
1750 To do so requires that we make it a function, so we do.
1751 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1752 * utils.c (do_cleanups): Remove the current cleanup from the
1753 chain *before* calling it, in case error() is called from it.
1754 The result won't be pretty, but won't be an infinite loop either.
1756 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1758 * dbxread.c (read_struct_type): Grok anon structs for C++.
1759 (vb_name, vptr_name): Null terminate these strings.
1761 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1763 Minor bug fixes from BSD Net2 gdb:
1765 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1766 returns 0, there is no previous frame.
1767 * breakpoint.c (commands_command): If !from_tty, don't call
1768 input_from_terminal_p().
1769 * dbxread.c (record_misc_function): Speed up slightly.
1770 (compare_psymbols): Ditto.
1771 * infcmd.c (do_registers_info): Take a second argument to
1772 determine whether to print float registers. "info registers"
1773 does not do so anymore. "info all-registers" does, now.
1774 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1776 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1777 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1781 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1782 executing_breakpoint_commands if we are interrupted by error.
1783 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1784 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1785 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1786 catch_errors() so we can setup the frame regardless of whether
1787 the shared libs work.
1788 * ieee-float.c (double_to_ieee_extended): Get exponent from
1789 right place in little-endian systems. From John Carey.
1791 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1793 * main.c: Remove unused terminating_signals and catch_termination().
1794 (long_options): Terminate with a zero element.
1795 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1796 (gdb_readline): Make call-compatible with readline.
1797 (init_signals): Improve comments re vfork vs. signal.
1799 * utils.c (prompt_for_continue): Use new gdb_readline().
1800 If we prompt for continuation, we don't let CR repeat the previous
1801 command, once we get back to a prompt. It's too easy to keep
1802 hitting CR, expecting "--more--" prompts, and have some long
1803 command start repeating on you.
1805 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1807 * blockframe.c (frameless_look_for_prologue): Speed up by
1808 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1809 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1810 Define two variants, one faster.
1811 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1812 and return zero, rather than giving an error.
1813 (setup_arbitrary_frame): Initialize the PC in the new frame.
1814 (skip_prologue): Add a second arg saying whether we're just
1815 checking for a frameless function or not.
1817 * core.c (core_open, core_close, core_xfer_memory): Move
1818 section table pointers and bfd* into the target_ops.
1819 (core_open): Allow errors in shared lib reading, etc.
1820 (core_files_info): Describe shared library sections.
1822 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1823 exec_files_info, set_section_command): Move section table
1824 pointers and bfd* into the target_ops.
1825 (add_to_section_table): Add BFD to section table.
1827 * target.c (target_xfer_memory, target_info): Pass target to
1828 xfer_memory and target_info functions.
1831 * gdbcore.h: Move struct section_table.
1832 * target.h: New home of struct section_table.
1834 * solib.c (solib_add): New argument is the target_ops whose
1835 section list is to be added to, if any. Reallocate the
1836 sections in that target to add any that come from shared libs.
1837 (throughout) so_sections renamed to sections.
1838 (solib_xfer_memory): Deleted.
1839 * tm-sunos.h (SOLIB_ADD): Add target argument.
1840 (SOLIB_XFER_MEMORY): Delete.
1842 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1843 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1844 from target_ops. It's the same on all targets. Add two section
1845 pointers to target_ops.
1847 * stack.c (find_relative_frame): Dump ancient algorithm for
1848 "down", just use handy "next" pointers.
1849 (frame_command): Don't error if there is no stack; let user
1852 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1853 modifies static state in the parent process; new_tty itself
1854 runs in the child and modifies the child's file descriptors
1855 to match the saved static state.
1856 * infrun.c (child_create_inferior): Call new_tty_prefork,
1859 * infptrace.c (child_xfer_memory): Add ignored target arg.
1860 * remote-eb.c (eb_xfer_inferior_memory): ''
1861 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1862 * remote-vx.c (vx_xfer_memory): ''
1863 * remote.c (remote_xfer_memory): ''. Rename from
1864 remote_xfer_inferior_memory.
1866 * main.c (main): Only try to attach "corefile" argument if
1867 it starts with a digit.
1869 * symfile.c (symbol_reloading): New "set/show" variable.
1870 (symbol_file_add): Shorten message about symbol reading.
1871 (add_symbol_file_command): Merge with add_syms_addr_command,
1872 since this should work on all targets now.
1873 (stop_whining): Default to zero, to shut up complaints
1874 about bad symbol tables on many systems.
1875 (free_named_symtabs): Just exit unless symbol_reloading.
1877 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1878 and add comment explaining shared library screw.
1880 * source.c: #if defined => #ifdef.
1882 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1884 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1886 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1888 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1889 (doc/Makefile knows how to make one for local config)
1891 * Makefile.in: use doc/Makefile for doc targets
1893 * doc/Makefile: GDB documentation now has its own Makefile
1894 doc/refcard.tex: renamed from "gdbrc.tex"
1895 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1896 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1899 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1901 * values.c (baseclass_addr): When reading target memory, use the
1902 length of the basetype, not the upper type. We've only malloc'd
1903 enough space for the basetype, leading to errors in free().
1905 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1906 ends up as a function specially, since we know the actual type of
1907 the pointed-to address. This (somewhat) fixes display of
1908 expressions that include misc_function_vector names. Try `cond 1
1909 !strcmp("a","b")' then `i b'.
1911 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1912 The child can be proceeded from inside wait_for_inferior in
1913 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1914 getting skipped in that case.
1916 * expprint.c (print_subexp): Use filtered output, since the
1917 subroutines we call use it, otherwise the output is horribly
1918 mangled, since output of wrappable stuff comes out late.
1920 * Makefile.in: Bump VERSION to 3.98.1
1922 * infrun.c (child_create_process): Use execlp to find the
1923 shell to exec our target program. This requires some fiddling
1924 with `environ' since there is no execlpe().
1926 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1928 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1929 Minor rearrangement of refcard permits two new make targets--
1930 gdbrc.dvi DVI output for refcard, using CM fonts
1931 gdbrc.ps PostScript refcard, using PS fonts
1933 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1937 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1938 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1940 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1942 * doc/gdb.texinfo: last changes for release.
1943 Minor typo and formatting fixes; incorporated most fixes remaining from
1944 filed mail commenting on earlier drafts.
1946 Added warnings: pipes don't work in run command;
1947 conditions are converse of assertions;
1948 step over fn without debug info goes to next fn;
1949 vars may have "wrong" values near fn entrance, exit
1951 Added example from Kingston on printing repeated nonadjacent values
1953 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1954 shell mode for signals
1956 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1957 doesn't sound so much like its parent "Stopping and Continuing"; also
1958 moved entries on continue to top of section, so they don't get lost.
1960 Improved installation directions in appendix, added manual formatting
1963 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1965 * configure.in: Remove xm.h and tm.h even if we aren't linking
1966 new ones, so "./configure sun4; ./configure none" does the right
1967 thing. Assume that alldeps.mak and depend are already built in
1968 srcdir, and avoid running "make" (particularly "make depend",
1969 which involves "gcc") from inside configure. Build Makefile
1970 directly rather than building Makefile.conf first.
1971 * configure: Regenerate with above changes.
1972 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1973 to 3.98. Revise gdb.tar.Z procedure to produce a file
1974 called gdb-$(VERSION).tar.Z but which unpacks into a
1975 directory called "gdb". Move non-source files out of
1976 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1977 (depend): Don't try to do "gcc expread.y".
1978 (expread.o): Update dependencies by hand.
1980 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1983 Fixed a variety of small typos that prevented info from formatting
1984 cleanly; altered too-long heading for GPL Appendix, as discussed
1985 w/RMS; Changed date on cover to July 91.
1987 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1990 (1) Applied some fixes due to comments from Larry Breed (easier ones
1991 through chapsec 5.2)
1992 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1993 it's broken in latest texinfo
1994 (3) Introduced *some* use of [] for optional arguments, where
1995 explanation is not simpler by listing cmd w arg and cmd w/out arg
1996 separately. Still not using @deffn.
1997 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1998 couple of headings are too long. Need patches to texinfo or revision
2001 * Partial update to README (which still needs work for this
2002 release!): (1) use of configure corrected for new script,
2003 (2) "make gdb.dvi" and "make gdb.info" mentioned.
2005 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
2007 * symtab.c (lookup_symbol): Don't complain right off about
2008 no debug symbols; use the misc function vector first.
2009 (list_symbols): Use misc function vector to find symbols
2010 that don't have debug info, and print them.
2011 (find_pc_symtab): Temporarily avoid fatal() when psymtab
2012 PC range doesn't match symtab PC range, as it does on the
2013 MIPS because our symtab reading isn't perfect.
2015 * dbxread.c (dbx_symfile_read): Make warning about
2016 "no debug symbols" slightly nicer.
2018 * source.c (select_source_symtab): If "main" symbol exists,
2019 but decode_line_spec can't find line info, don't just return
2020 a zero; try other source symtabs or give an error.
2022 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
2023 their low addresses first, then rip through fixing high addrs.
2025 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
2026 <runene@ifi.uio.no>.
2027 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
2029 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2031 * Minor, mostly mechanical, cleanup of doc subdir for clean
2032 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
2033 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
2035 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
2037 Mostly MIPS and general symbol-reading fixups.
2039 * doc/gdbint.texinfo: Add documentation on symbol-reading
2042 * mipsread.c: Remove kludges around #include "ecoff.h".
2043 Remove redefinitions of a_magic, etc, no longer used.
2044 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
2045 Fix global overview comments to match symfile.c protocol.
2046 (mipscoff_new_init): Eliminate cur_hdr if we have one.
2047 (mipscoff_symfile_read): Eliminate unused code. Avoid
2048 sorting all the symtabs, when all we have read here is psymtabs.
2049 The symtabs are sorted as they are created anyway. Tell
2050 condense_misc_bunches whether we're mainline.
2051 (psymtab_to_symtab_1): Pass filename when recursing, to make
2052 stack trace more informative.
2053 (parse_partial_symbols): Assume cur_hdr as argument.
2054 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
2055 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
2056 the TYPE_NAME of char *, since that's done in symfile.c.
2057 (free_numargs, parse_symbol, add_symbol, add_block,
2058 shrink_linetable): Declare these fns void.
2059 (upgrade_type): Convert tree of if's to switch. Clean up
2060 bogus "off == 0" handling with a complaint. Avoid setting
2061 field bitpos and bitsize of array with lower and upper bounds.
2062 Check specified bitsize of elements against their actual type's
2063 bitsize, and complain if different. Complain about unknown
2065 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
2066 (psymtab_to_symtab_1): Print names of subsidiary files that
2067 are being read in. FIXME, we read far too many files. This code
2068 is not the problem, the problem is in parse_fdr where the psymtabs
2070 (cross_ref): Result should indicate that we used one aux entry
2071 normally, or two if we encountered a "next" entry. This used
2072 to leave the caller pointing at the wrong aux entry.
2073 (add_symbol): If overflowed cur_block, reallocate it larger,
2074 chase all pointers to it, and complain(), rather than clobber memory.
2075 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
2076 (new_field): Only allocate one field initially, not two.
2077 Pull ++ out of macro argument. Simplify.
2078 (_initialize_mipsread): Avoid initialization of importd
2079 global_psymbols and static_psymbols.
2081 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
2082 to properly set pst->symtab; avoid searching for it.
2083 (symfile_fns): Improve comments, add a FIXME.
2084 * dbxread.c: Update comments to reflect symfile protocol.
2085 (read_ofile_symtab, end_symtab): Return the symtab.
2086 (psymtab_to_symtab_1): Set pst->symtab.
2088 * coffread.c (coff_symfile_read): tell condense_misc_bunches
2089 whether we're mainline.
2091 * symfile.h (sym_fns): Remove unused sym_discard member.
2092 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
2094 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
2095 the environment variable is not.
2096 * infcmd.c (finish_command): Use filtered printfs.
2097 * cplus-dem.c: Add struct tags to a few unnamed structs.
2098 * valops.c (value_coerce_array): Improve comments.
2099 * valprint.c (type_print_varspec_suffix): Print array size only
2100 if greater than zero.
2101 * m88k-tdep.c: Shift some lines left by one space, that had
2102 apparently been trashed at some point.
2103 * TODO: More things to do, a few got done.
2105 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2107 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
2108 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
2110 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
2111 * expread.y, findvar.c, symmisc.c: Ditto.
2112 * printcmd.c (address_info): Update printed forms of LOC_
2113 symbols. Elim LOC_EXTERNAL.
2114 (print_frame_args): Keep track of param stack offsets before
2115 re-looking up to find the local register param is kept in.
2117 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
2118 Further integration of mipsread into gdb. Eliminate unused
2119 routines, duplicate declarations. Handle static symbols in
2120 psymtabs as well as external symbols. When reading symtabs,
2121 insert symbols into the correct block (global, static, or a local
2123 (read_mips_symtab, parse_partial_symbols): Don't pass useless
2125 (mipscoff_symfile_read): Don't call select_source_symtab.
2126 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
2127 rather than SYMBOL_VALUE.
2128 (parse_external): Comment clobbering of top_stack.
2129 (parse_partial_symbols): Update comments. Allocate and parse
2130 static symbols as well as external symbols. FIXME, enum values
2131 are not handled in this pass, but should be. Inline new_psymbol.
2132 Use SYMBOL_VALUE_ADDRESS.
2133 (psymtab_to_symtab_1): Read symbols into global static block
2134 by default (until enter some function's local block context).
2135 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
2136 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
2138 * source.c (select_source_symtab): Select a source symtab
2139 from either the symtabs or, failing that, the psymtabs.
2140 (list_command): Update error message.
2141 (forward_search_command, reverse_search_command): Use getc, not
2142 fgetc, for speed. FIXME, add comment about buffers that die if
2143 overrun by long line.
2145 * values.c (unpack_field_as_long, modify_field): Avoid shifting
2146 by an entire word, which is not portable, if we have a 32-bit
2147 field. (Code in dbxread.c already turns such bitfields, if
2148 aligned, into ordinary ints, but fixing this will help for other
2149 symbol formats and for future changes.)
2150 * core.c (core_open): Handle ANSI const brain death.
2151 * utils.c (vprintf): Fix varargs typo.
2153 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2155 * findvar.c (find_var_value): Handle &function better.
2156 * TODO: Document work needed on &fn and &array.
2157 * printcmd.c (print_address_symbolic): New arg is the prefix
2158 to print if a name is printed.
2159 (print_address_demangle): Honor "set print address" now.
2160 Use new arg above to improve spacing of output.
2161 * valprint.c (val_print): When printing function pointers,
2162 print symbolic form too.
2163 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
2165 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2167 * core.c (memory_error): Reword error msg to mislead less.
2169 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
2171 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
2172 parse_partial_symbols): Use newer BFD internals (external_filehdr
2173 and external_aouthdr), byte-swap the fields that we care about
2174 before using them, and make the file header data local to
2175 read_the_mips_symtab rather than global.
2177 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
2179 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
2180 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
2182 * main.c (command_line_input): Flush stdout and stderr
2183 before every call to readline. This reportedly fixes a bug
2184 that comes up in Sys V running emacs-gdb and/or xxgdb,
2185 when stdin/out are pipes or sockets.
2187 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2189 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
2190 Avoid declaring Makefile dependencies, because GNU Make stupidly
2191 tries to update it if we do.
2193 * coffread.c: Revise for minor changes to bfd internal coff
2196 * configure: If -template= is given a relative path, make it
2197 absolute before recurring in subdirectories.
2199 * configure, configure.in, Makefile.in: Install "configure" script
2200 as replacement for config.gdb.
2201 * config.gdb, Makefile.dist, Makefile.sdir: Remove
2202 * README: Update for configure, mostly. FIXME.
2204 * Add dec3100 as equivalent to littlemips. Indicate in all host &
2205 target config files that they are for the host. When the lines
2206 get copied into the Makefile, this makes it more obvious what's
2209 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2211 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
2212 tabs, which end up in the disassembler output inadvertently.
2214 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2216 Make it compile cleanly in an ANSI GCC2 environment.
2218 * blockframe.c: <stdio.h>
2219 * cplus-dem.c: free takes a void *, ifdef __STDC__
2220 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
2222 * defs.h (alloca): Avoid doing anything if alloca already def'd.
2223 * stddef.h, stdlib.h: Remove these files.
2224 * symtab.c: Avoid declaring qsort, close.
2225 * symfile.c: Avoid declaring close.
2226 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
2227 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
2229 Assorted other changes.
2230 * dbxread.c: include "libaout.h", not "liba.out.h".
2231 * printcmd.c (print_frame_args): Set recurse properly for
2232 indentation of struct and array parameters.
2233 * valops.c (value_cast): Allow cast to void.
2234 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2235 single_step() in a target-independent fashion.
2236 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2237 set up to be ready to continue. This makes us target independent.
2238 * infptrace.c (child_resume): Remove call to single_step; now
2239 can single step a SPARC target of any kind.
2241 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2243 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2244 docn into separate sections---basically chapters, plus two loose
2245 pieces that can be configured to go in different places. This
2246 allows GNU m4 to preprocess the manual without coredumping.
2248 * Makefile.dist: tell TeX where to find texinfo.
2250 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2252 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2253 the new target "rdl-apps.texinfo" which captures the Makefile
2254 variable that records where to find the Readline libraries.
2256 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2258 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
2259 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
2260 * defs.h (const, volatile): Only define if not already defined.
2261 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2263 * README: Update for release 3.95.
2264 * config.gdb: Don't create readline dir in subdir builds.
2265 * main.c: Include with "..." form for non-system include files,
2266 so "gcc -MM" for "make depend" works.
2267 Include readline files with "...h" rather than <readline/...h>.
2268 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2270 * coffread.c: Undo minor damage done by Rich Pixley. Use
2271 different internal and external representations of COFF
2272 data structures. Use new BFD routines for swapping them in and
2274 * symfile.c (free_named_symtabs): Avoid freeing file names that
2275 are null or empty. Old i960 tools seem to produce files that
2276 claim to have empty names, causing each successive file read
2277 to blow away the previous one.
2278 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2279 Move deferred_stores to top of file, but don't separate its
2280 #define's from its variable. Add commentary.
2281 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2282 favor of keeping the (working) config.gdb. Move readline
2285 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2287 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2289 * infptrace.c (fetch_registers): no result, since now void.
2290 * tconfig/news: target depends on m68k-tdep too.
2292 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2294 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2297 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2298 applied various small fixes due to or inspired by RMS comments
2300 * doc/gdb.texinfo: finished using all RMS comments, save those for
2301 appendices on readline and cmd history (which are in other source
2304 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2306 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2307 chapter 9; (2) documented 'break' command's menu mode for
2308 overloaded names, in response to hgs problem report C++ p-31
2310 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2312 * doc/gdb.texinfo: (1) better introductory example; (2) more
2313 consistent use of @code, @samp, @file, @kbd throughout; small
2314 cleanups to first three nodes; (3) new "Contributors" node;
2315 (4) Appendix, Renamed Commands; (5) divert specialized startup
2316 instructions to "Targets" chapter for generic manuals, while
2317 leaving them up front for manuals specific to specialized
2318 environments; (6) apply fixes from RMS comments through chapter 4.
2320 * pretex.m4: modify explanatory text slightly (and redefine
2321 "regexp") to keep GNU m4 from complaining. (It still crashes
2322 later, but one step at a time...)
2324 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2326 * readline/readline.c (update_line): Avoid dereferencing a pointer
2327 before comparing it to its bounds. Saber caught this.
2328 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2329 and only set PC if tgetstr returned non-null. Saber caught this.
2331 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2333 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2334 stuff for config manual) here where it counts; updated
2335 to use new subdir structure (gdb/doc/).
2337 * Makefile: generated from above via
2341 * gdbint.texinfo: added instructions on generating gdb.info* files
2342 locally for release. These are ordinary info
2343 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2344 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2345 to generate these, so we distribute them already formatted.
2347 * gdb.texinfo: included full Info node and menu crud (as generated
2348 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2350 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2351 put in comments-for-future gdb.info target (one day makeinfo will
2354 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2356 * gdb.texinfo: Updated to include new or old undocumented
2357 commands, at least the following (perhaps some others I forgot to
2358 record): info f, info float, info path, info program, info s, info
2359 set, info source, info terminal, info types, info user, set/show
2361 Also covered all recent GDB command renames for v4.
2363 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2365 * mipsread.c: Rather than keeping count of how many symtabs
2366 and psymtabs we have, for sorting purposes, count them when
2367 we need to sort. This fixes bug in rereading of symbol tables.
2369 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2371 * infcmd.c: renamed "info path" to "show paths"
2372 * gdbrc.tex: documented above.
2374 Wed May 8 04:51:11 1991 John Gilmore (gnu at cygint.cygnus.com)
2376 * remote.c: Fix comments.
2377 * utils.c (error): Force out any pending wrap output.
2379 Sat May 4 11:11:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2381 * Makefile.dist: Roll VERSION to 3.95.
2382 Fix up "saber_gdb" to work again.
2383 * saber.suppress: Update.
2385 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
2386 symtab.h, target.c, target.h: Lint.
2387 * core.c: setup and select frame after reading shared libs,
2388 else reading shared libs will clobber them. Lint.
2389 * utils.c (error): Force out any buffered wrap text.
2391 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2393 * remote.c: Remove decls of memory_insert_breakpoint
2394 and memory_remove_breakpoint, no longer used. (Suggestion of
2397 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2398 to make it easier to interface to "configure"'d libraries.
2400 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2402 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
2403 aliases for set/show print.
2405 Thu May 2 11:22:02 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
2407 * coffread.c (coff_sym_fns) [TDESC]: Make the type be m88kbcs.
2409 * m88k-tdep.c (IEEE_isNAN): New function.
2411 * infrun.c, m88k-tdep.c, m88k-xdep.c: Change
2412 initialize_{tdesc,dcontext} to init_{tdesc,dcontext}.
2414 * infrun.c [TDESC]: Add a bunch of crud.
2416 * xm-88k.h [__GNUC__]: Don't define memset.
2418 * m88k-xdep.c: #if 0 out push_breakpoint.
2420 * tm-88k.h: Define GET_SAVED_REGISTER.
2422 * tm-88k.h: Define DGUX.
2424 * m88k-opcode.h (UEXT, SEXT, MAKE): Put parentheses around arguments.
2426 * m88k-pinsn.c (sprint_address): Declare at top of file.
2428 * m88k-xdep.c: #if 0 out core_file_command.
2430 * values.c ({unpack_,value_as_}pointer): Just call

2904 Sun Apr 14 23:08:34 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
2906 * inftarg.c (child_open), remote-vx{,.68}.c (vx_proc_open):
2907 New function to give correct error message.
2909 Thu Apr 11 17:19:41 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
2911 * target.h: Add to_doc and target_preopen.
2912 target.c: Add target_preopen and target_command.
2914 (add_target): Call add_cmd and mess with targetlist->doc.
2915 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
2916 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.
2917 Call target_preopen from open routine.
2919 * main.c: Rename editing_info to show_commands.
2920 (_initialize_main): Rename "info editing" to "show commands".
2922 * source.c: Rename directories_info to show_directories.
2923 (_initialize_values): Rename "info directories" to "show directories".
2925 * values.c: Rename convenience_info to show_convenience.
2926 (_initialize_values): Rename "info convenience" to "show convenience".
2928 * copying.awk (_initialize_copying): Rename "info copying" to
2929 "show copying" and "info warranty" to "show warranty".
2930 Rename {copying,warranty}_info to show_{copying,warranty}.
2932 * symfile.c: Rename add_syms_command to add_symbol_file_command.
2933 (_initialize_symfile, add_syms_addr_command):
2934 Rename add-syms to add-symbol-file.
2936 Thu Apr 18 18:08:30 1991 John Gilmore (gnu at cygint.cygnus.com)
2938 * symfile.h (free_named_symtabs): Rename from free_named_symtab.
2939 * symfile.c (clear_symtab_users_once, cashier_psymtab,
2940 free_named_symtabs): Move these routines from symmisc.c.
2941 * symmisc.c (same): same.
2942 (free_symtab): Make non-static.
2943 * symtab.h (free_symtab): Declare as exported void fn now.
2944 * dbxread.c (end_symtab, end_psymtab): Change comments.
2945 (initialize_dbxread): Call dbx_new_init() in case the first
2946 command is add-symbols.
2947 * target.c (dummy_target): Permit add_syms_addr_command.
2949 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2951 Permit symbols to be superseded when new symbol files have
2952 been read in, particularly for VxWorks.
2954 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
2955 to the main file, as well as to include files. Also, put global
2956 functions into the global psymtab, to make "i fun" work.
2957 (end_psymtab): Free named symtabs and psymtabs for a file, once a
2958 new psymtab for it has been read.
2959 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
2960 a file, once a new symtab has been read for it.
2961 * mipsread.c: FIXME. We need to do the same for MIPS, but it
2962 looks harder to determine the top-level block before it's been
2963 queued to the psymtab list.
2965 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
2966 If we have wiped out any old symbol tables, clean up at end of
2968 (symbol_file_command): Don't reference symfile_fns if it's zero.
2970 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
2971 defines for the blocks of a blockvector that contain global and
2972 file-static symbols and the first of the smaller scope contours.
2973 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
2974 decode_line_1, make_symbol_completion_list): Use the above.
2975 * coffread.c (end_symtab, patch_opaque_types): Ditto.
2976 * dbxread.c (end_symtab): Ditto.
2977 * expread.y (block): Ditto.
2978 * mipsread.c (throughout): Ditto.
2979 * symmisc.c (free_named_symtabs): Ditto.
2981 * symtab.c (list_symbols): Process the first symbol of the
2982 static psymbols list.
2983 (types_info): Restore this function from its untimely #if 0.
2984 It's not perfect, but it is better than nothing.
2985 (_initialize_symtab): Restore "info types".
2987 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2989 * m68k-stub.c: Remote stub for 680x0's, created from
2990 rem-m68k.shar (which is removed).
2991 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
2992 Remove RCS log stuff now that we use CVS and it blows our diffs.
2994 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2996 * symmisc.c (free_named_symtab): Make it work, in its current
2997 kludgy fashion. Change result to indicate if we blew away bkpts.
2998 * dbxread.c (end_symtab): Accumulate result from
2999 free_named_symtab and print warning if we blew user's state.
3000 * symfile.h: free_named_symtab now returns an int.
3002 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
3004 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
3005 is the first symbol read, even if not mainline.
3006 (dbx_psymtab_to_symtab): symfile might be zero, cope.
3007 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
3008 (set_section_command): New command ("section xxx yyy" -- should
3009 be renamed to "set section xxx yyy" FIXME) which sets the
3010 base address of a section of the exec file, overriding the
3011 virtual address that BFD reports.
3013 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
3015 * exec.c: Add add_syms_addr_command to exec_ops, so you can
3016 load symbols at any address while examining an exec file.
3018 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3020 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
3021 for printing the float info is host-dependent, not
3022 target-dependent. FIXME.
3023 * i386-pinsn.c: Move #includes to top, remove useless ones.
3024 * i386-tdep.c: Don't bother including <.../reg.h> since we
3025 don't use it (and it doesn't exist on host systems).
3027 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
3028 Convert negative numbers properly.
3029 (ieee_test): Make numbers really random; fix format arg.
3031 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
3032 * core.c (core_detach): Unpush core_ops, which might not be on
3033 top. We used to just pop the top, which broke things. Don't
3034 need dont_repeat() any more.
3035 (core_file_command): Psst! Don't repeat it.
3036 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
3037 * expprint.c (print_subexp): Avoid switch fallthru on
3038 BINOP_ASSIGN_MODIFY, so we can print += and such.
3039 * frame.h: Fix typo.
3040 * inflow.c (kill_command): After killing inferior, print our
3041 current frame in the core file, if we have one.
3042 (generic_mourn_inferior): When inferior dies, either select
3043 the current frame (in the new target, e.g. core file), or
3044 set both the current and selected frames to NULL.
3046 Changes from Peter Schauer.
3048 * infptrace.c: Avoid <sys/ptrace.h> on USG.
3050 * Make all file names fit in 14 characters (sigh and damn!):
3051 mv hp300hpux-xdep.c hp300ux-xdep.c
3052 mv symmetry-xdep.c symm-xdep.c
3053 mv symmetry-tdep.c symm-tdep.c
3054 mv convex-opcode.h convx-opcode.h
3055 mv tm-vxworks960.h tm-vx960.h
3056 mv tm-vxworks68.h tm-vx68.h
3057 mv Makefile.srcdir Makefile.sdir
3058 mv gdb-int.texinfo gdbint.texinfo
3059 mv remote-sa.m68k.shar rem-m68k.shar
3060 mv remote-multi.shar rem-multi.shar
3061 * Makefile.dist, README, config.gdb, convex-pinsn.c,
3062 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
3063 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
3066 * command.c (user_info_1, user_info): New command for listing
3067 the user-defined commands.
3069 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
3071 * dbxread.c (really_free_pendings): Clear file_symbols
3072 and global_symbols after freeing them; otherwise, running
3073 this function twice (if it appears twice on the cleanup
3074 chain), we try to free things twice.
3076 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
3077 based on text_addr (the address of text in core), not on addr (the
3078 offset between text in the .o file and in core). This change
3079 is from Peter Schauer.
3081 * main.c: Define ALL_CLEANUPS as a cast of zero.
3082 (return_to_top_level): Use it.
3083 (main): Do all cleanups after each command run as part
3084 of the gdb startup sequence. Also do all cleanups before
3085 entering the command loop, and every time we exit the command
3086 loop and reenter. Before, the cleanups from the startup sequence
3087 were being left undone until the first error!
3088 (command_loop): Rename do_nothing cleanup to command_loop_marker
3089 so we can see it easily when examining the cleanup chain.
3090 (init_signals): Add another do_nothing for signal handling.
3091 (quit_command): Only try to kill target if it has execution.
3092 Problems in the target stack got us into a state where
3093 inferior_pid was nonzero but none of the targets had execution.
3094 In this state you couldn't exit gdb.
3096 * dbxread.c: Two changes from Peter Schauer.
3097 (echo_command): Fflush output after an echo command.
3098 (show_history): Pass all args to cmd_show_list.
3100 * utils.c (init_malloc): Call mtrace to turn on tracing
3101 if the environment variable MALLOC_TRACE is set to a file name.
3102 * mtrace.c: Add source file which provides a log of every malloc,
3103 free, and realloc to a trace file.
3104 * mtrace.awk: Add source file which analyzes the trace file.
3105 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
3106 (VERSION): Roll to 3.94.3.
3108 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
3109 (check_duplicates): Don't bother with watchpoints.
3110 (set_raw_breakpoint): Comment about danger of this routine.
3111 (watch_command): Parse and eval all args before calling
3114 * solib.c (find_solib): Avoid error in referencing memory to
3115 see if any more shared libraries have been added. This is
3116 particularly useful if the target has terminated. Bug reported
3119 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
3120 in bringing up 3.94.2 on the Sun-3.
3122 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
3123 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
3124 expression (in scope) before reenabling watchpoint.
3125 * signame.c (init_sigs): Add missing declaration of i, fix
3126 sys_siglist declaration.
3127 * source.c (list_command): Fixed range computation to use
3129 * stack.c (backtrace_command): Do not allow command if target has
3130 no stack, print informative error message.
3131 * target.c (target_command): Do not write into command line
3132 because this fails if the target command is used in a user defined
3133 command. [This change was enhanced by gnu to support any-
3134 unique-prefix matching on target names.]
3135 * valops.c (value_struct_elt): Avoid infinite loop on an
3136 erroneous attempt to print the member of function (try p main.p).
3138 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3140 * expread.y (name_no_typename): Avoid reduce/reduce errors
3141 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
3142 Since the GDB parser really doesn't use name_no_typename in a
3143 name-only context, the parser can't tell the diff between
3144 names and numbers here. Avoid allowing a name_no_typename
3145 to be a NAME_OR_*INT to resolve the conflict.
3147 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3149 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
3151 * valprint.c (val_print_fields): bitfield printing didn't handle
3152 byte order. Indirect through a few more fns to cope.
3154 * values.c (modify_field): also cope with byte order.
3156 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
3158 Cleanup for release 3.94.2:
3160 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
3161 include files. Roll version to 3.94.2.
3163 * coffread.c (init_stringtab): Read length into unsigned char
3164 array before swapping; don't assume 32-bit longs.
3166 * target.c (target_info): Don't bother with get_sym_file, just use
3167 the symfile global variable.
3168 * symtab.h, symfile.c (get_sym_file): Delete it.
3170 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
3171 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
3172 (read_type): Replace one more error() with complain().
3174 * mipsread.c (parse_partial_symbols): Replace printf with complain.
3176 * i960-tdep.c: Fix copyright attribution.
3178 * config.gdb: Quote all backquotes in doublequotes. You can
3179 quote me on that. BSD 4.4 shell found this one.
3181 * infptrace.c (throughout): The third argument to ptrace is an
3184 * infrun.c (wait_for_inferior): When program has terminated, we
3185 have to call target_terminal_ours before we pop that target off
3186 the stack (e.g. before a call to target_kill or
3187 target_mourn_inferior). This fixes problem where a program
3188 terminates, then GDB stops for (tty output) and you have to type
3189 "fg" to the shell to resume it. FIXME: This code for what to
3190 do after termination really should be in normal_stop instead.
3192 * gdbcore.h (read_memory_check): Change declaration; it changed
3195 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
3196 4.4 prereleases, this avoids a bug in their sgtty compatability
3198 * remote.c: Use terminal.h rather than hand-rolling the same.
3200 * signame.c, signame.h (psignal): Arg is unsigned, not int.
3201 * utils.c (strsave, strstr): Fix arg types.
3202 * valprint.c (val_print): lint
3204 MIPS symbol table support from Per Bothner:
3206 * symfile.c (symtab_fns): Remove initializer table that needs to
3207 be hacked for each new symbol file format supported.
3208 (add_symtab_fns): New function, chains symbol table
3209 handlers into the global list.
3210 (symfile_init): Search this list.
3211 * symfile.h: Add next pointer, declare add_symtab_fns.
3212 * coffread.c (_initialize_coffread): Call add_symtab_fns.
3213 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
3215 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
3216 symbol *). Thus, we no longer need the hack to trash
3217 pst->filename. Good, since that hack confused code in symfile.c!
3219 (reorder_symtabs, destroy_all_symtabs): Removed static
3220 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
3221 Instead, the latter now uses a temporary array (stack-allocated
3222 from an obstack, and then freed).
3224 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
3225 haven't been set in the outermost stBlock of a procedure. This was
3226 a problem with f77 binaries on Ultrix 4.?.
3228 (new_symtab, new_symbol, new_type): Continue changing code to use
3229 obstacks more and otherwise conform to dbxread internal style.
3230 Made the free_code of symtabs be free_linetable (as in dbxread)
3231 instead of free_contents. This implies memory leaks when reading
3232 a new symbol table, until the conversion is finished. Did change
3233 (struct symbol) and (struct type) to be allocated on the
3234 symbol_obstack. Blocks and blockvectors are among the things
3237 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3238 tested much, but it solved one problem (reported by Meissner), and
3239 cleans up some other things. The problem happened when an
3240 included file contains actual code (functions) and not just
3241 definitions. The mips coff is a little inconvenient there, since
3242 it may cause a procedure to be mapped to the wrong psymtab.
3244 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3245 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3246 this will need work for the new core paradigm.
3248 Opcode patches from the net:
3250 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3251 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3252 missing altogether - they are added here. From Bruce Bauman.
3253 * mips-opcode.h: The low mask for C0 instructions was too small.
3254 From Garrett Lau. I modified the fix to check the entire 32-bit
3257 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3260 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3262 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3264 * dbxread.c (read_type): Pointer subtraction (value_sub in
3265 valarith.c) sometimes failed because the types of the
3266 pointers being subtracted were not identical.
3267 These differed because dbxread.c was allocating pointer types
3268 using dbx_alloc_type+smash_to_pointer_type instead of
3269 lookup_pointer_type. I failed to find a justification for the
3270 former, so I changed it to use the latter. Similarly, I
3271 replaced smash_to_function_type by lookup_function_type,
3272 and smash_to_reference_type by lookup_reference_type.
3274 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3275 _initialize_mipsread): corresponding changes.
3277 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3279 * source.c (mod_path): Do tilde_expand on each component of the path,
3280 rather than on the (list of) paths as a whole.
3281 (print_source_lines): Set first_line_listed in addition to
3282 current_source_symtab and current_source_line. If the source was
3283 not findable, after a "dir" command to fix the problem,
3284 a "list" would get the wrong lines.
3286 While I was there... (gnu):
3288 * dbxread.c (read_type): Change error to complaint.
3290 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3292 First attempt at detailed understanding of symbol table memory alloc.
3294 * dbxread.c (dbx_symfile_read): Free our string table if we
3295 aren't the mainline. Free the "info" struct since we're done with
3297 (init_psymbol_list): Free any previously allocated psymbol lists.
3298 (): FIXME: Should realloc-down the psymbol lists when done reading
3299 the main symbol file?
3301 * symmisc.c (free_symtab): Free fullname field too.
3303 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3304 (REGISTER_ADDR): Make result type unsigned int.
3306 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3307 define REGEX must also define REGEX1 (its dependency).
3309 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3311 * tconfig/i960: No longer works, points you at vxworks960 or
3314 * xgdb.c, XGDB-README: Remove file. Users can get the much
3316 * Makefile.dist: Remove all trace of xgdb.
3318 * breakpoint.c (breakpoint_1): Pass demangle arg to
3319 print_address_symbolic.
3320 (clear_breakpoints): Remove unused function.
3321 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3322 (breakpoint_re_set): Use catch_errors to do them all anyway.
3324 * gdb-int.texinfo (Host versus Target): Add section on what is
3325 a "host" feature versus what is a "target" feature.
3327 * infcmd.c (path_command, path_info): Handle the PATH variable
3328 (object search path) as conveniently as the source search path.
3329 * environ.c (set_in_environ): Set some vars in GDB's environment,
3330 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3331 * source.c (mod_path): New function, from guts of
3332 directory_command, modifies a path. Used by path_command.
3333 (directory_command): Call it.
3334 * defs.h (strsave): Declare.
3336 * utils.c (sevenbit_strings): Add new printing option.
3337 (printchar): Use it.
3338 (strsave): Provide this handy helper routine.
3339 (set_width_command): Rename set_screen_width_command.
3340 (_initialize_utils): "set screen-width" => "set width";
3341 "set screen-height" => "set height"; add sevenbit-strings.
3343 * infcmd.c (do_registers_info): Print floating point registers
3344 in raw hex as well as float format, regardless of whether it is
3345 a "virtual" convertible register.
3346 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3347 regs as a double, just in case it's being used that way.
3348 * values.c (unpack_long): Comment on array/function coercion.
3349 (unpack_double): Argument is in target byte order now. For
3350 integer arguments, just call unpack_long and float the result.
3351 * m68k-tdep.c: include defs.h for "const" handling.
3352 * remote-nindy.c: Use ieee-float stuff.
3353 (nindy_fetch_registers): Unpack double regs to host double, then
3355 (nindy_store_registers): Pack extendeds to host double, flip
3356 around by misusing unpack_double, send as target double.
3358 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3359 zero, as when stopped at the first instruction of a process.
3361 * blockframe.c: Fix filename in comment (param.h => tm.h).
3362 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3363 * tm-68k.h: Fix typos.
3365 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3367 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3369 * coredep.c (fetch_core_registers): Pass end-address of register
3370 section to register_addr as expected. Don't call supply_register
3371 if we'd just pass it garbage.
3373 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3375 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3377 * target.c (push_target, target_info): Cast enums to int for < or
3380 * stack.c (print_frame_info): Identify source file & line
3381 even if we can't print it.
3383 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3385 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3387 Clean up IEEE floating point support.
3389 * ieee-float.h: New file.

3395 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3396 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3397 double_to_ieee_extended.

3399 * m68k-tdep.c: Define ext_format_68881.
3400 * sparc-tdep.c: Define ext_format_sparc, though unused.
3401 * Makefile.dist (HFILES): Add ieee-float.h.
3402 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3405 Obsolete the "coffstrip" program in favor of using BFD's strip.
3407 * nindy-share/coffstrip.c: Remove file.
3408 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3409 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3410 * tconfig/nindy960: Remove reference to coffstrip.o.
3412 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3414 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3416 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3417 * dbxread.c: Remove static symfile_bfd.
3418 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3420 * inftarg.c (child_detach): Pop the child_ops vector if the
3421 detach is successful.
3422 * remote-nindy.c (nindy_create_inferior): Don't push a new
3423 nindy_ops since nindy uses the same one for execution and memory
3425 * core.c (core_ops): Use child_attach and child_create_inferior
3426 rather than default attach and create_inferior functions.
3428 Handle floating point registers in core files.
3430 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3431 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3432 This version untested since BFD doesn't yet support sun3 core
3434 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3435 conventions. Fix comments and style. This version has not
3436 been compiled yet, since we have no HP inhouse.
3437 * core.c (get_core_registers): Look for two sections, ".reg"
3438 and ".reg2", and pass both to fetch_core_registers sequentially.
3440 Revise directory path yet again.
3442 * source.c (forget_cached_source_info): Not static any more.
3443 (init_source_path): New default source path is "$cdir:$cwd".
3444 (dir_command): Handle variable arguments ($cdir, $cwd).
3445 (source_info): Print "Compilation directory" rather than
3446 "Originally compiled in" to remind people of $cdir.
3447 (openp): If the path contains $cwd, use current directory.
3448 (open_source_file): If compilation directory is known, replace
3449 first $cdir in path with the compilation directory.
3450 (print_source_lines): Even if we can't print the lines, set the
3451 current symtab and line for future commands like "info source" or
3452 "breakpoint". Also, error message now contains the file name,
3453 line number, and file access error message.
3454 (_initialize_source): Fix help text to describe changes.
3455 * main.c (cd_command): Forget cached source info when we chdir.
3456 * utils.c (strstr): Add simple implementation.
3458 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3460 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3461 Byte-swap COFF symbol tables if necessary when reading them in.
3462 Use complain() to replace error message in one spot. Needs
3463 corresponding change in bfd/coff-code.h to make some symbol
3464 swapping routines non-static.
3466 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3468 Merge changes from Eirik Fuller, for UTek.

3471 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
3472 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3473 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3474 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
3475 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
3476 declarations of errno.
3478 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3480 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3481 <rpc/rpc.h> and <rpc/types.h>.
3483 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3485 * i960-tdep.c (examine_prologue): Add new argument limit,
3486 which stops the scan at the end of the prologue, or at the PC.
3487 This fixes a problem where it walks down into the code for the
3488 user's statements if that code looks like function prologues.
3489 Mark Fox and I have been bouncing this code back and forth, making
3490 small changes to it. Callers changed to match.
3492 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3494 Cleanup for gdb-3.94 release final:
3496 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3497 the .c files from vx-share and nindy-share, from the various
3498 macros, since they are not found via ALLDEPFILES.
3499 (SFILES): Add tm-i960.h.
3500 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3501 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3503 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3504 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
3506 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
3508 * am29k-tdep.c: Add contribution line.
3509 (examine_prologue): Cache information about function prologues in
3510 the misc-function-vector to avoid lots of references over the
3511 serial line while examining instructions.
3513 * core.c (core_close): New function made from cleanup_core.
3515 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3516 remote-vx.c, remote.c, target.c, target.h,
3517 Update target_ops vector to add attach, close, and load entries.
3518 Use add_syms_addr_command, not add_file_addr_command, for
3519 add_file. Break out close routine from existing code.
3521 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3522 they are in an obstack.
3523 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3525 (define_symbol): Add symbol type parameter; change callers;
3526 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3527 it to influence the symbol class on the i960.
3528 (define_symbol): Swap LOC_CONST's into target byte order.
3530 * exec.c (exec_close): New function.
3531 (exec_file_command): Call it.
3533 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3534 Fix byte order of frame pointer.
3535 (read_var_value): Result of 0 if var's value can't be found,
3536 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3537 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3538 (locate_var_value): Use read_var_value and use its lazy address
3539 as the location of the var's value. Lint.
3541 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3544 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3545 obsolete Intel versions in favor of vxgdb versions.
3546 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3547 code dealing with byte order of values, which Intel did in host byte
3548 order rather than gdb-4's target byte order.
3549 (i960_frame_chain_valid): Move to nindy-tdep.c.
3550 (examine_prologue, skip_prologue, frame_find_saved_regs,
3551 frame_args_address, leafproc_return, saved_pc_after_call,
3552 pop_frame): Add vxgdb versions from Mark Fox.
3553 (examine_prologue, frame_struct_result_address): Add code
3554 to deal with the saved value of G13 (struct return address
3556 (frame_args_address): Modify Mark's version to prefer the
3557 saved value over the current value in the topmost frame.
3558 Cache result in the frame info to avoid performance hair in
3560 (print_fault): Add gdb960 code for printing faults.
3561 (_initialize_i960): Actually call check_host.
3563 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3564 add stub routines. FIXME, these currently just return zero!
3566 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3567 (attach_command): Call target_attach, not target_open, now.
3569 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3570 (child_attach): Rename from child_open.
3571 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3572 don't confuse it with a zero step_resume_break_address.
3574 * inftarg.c (child_detach): Eliminate inferior_pid test.
3575 (child_files_info): Clean up message a bit.
3576 (child_ops): Use child_attach, not child_open, to attach.
3578 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3579 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3580 findvar.c to here, since it depends on the contents of the
3581 shadow_contents of breakpoints, but keep if #if 0 since it is
3584 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3587 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3588 (ptype_command, display_command): Eliminate have_inferior_p and
3589 have_core_file_p in favor of target_has_stack or
3590 target_has_execution.
3591 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3592 code for actually finding the values of arguments, though we still
3593 keep track of the maximum stack offset for use in printing unnamed
3594 arguments. Handle missing FRAME_ARGS_ADDRESS.
3596 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3597 (struct nindy_regs): Define registers passed to/from nindy.
3598 (nindy_fetch_registers, nindy_store-registers): Translate between
3599 nindy and GDB formats for the registers.
3600 (dcache_init): Statically allocate the cache, since it was being
3601 allocated by a malloc that was never freed anyway.
3602 (nindy_create_inferior): Error, not core dump, if no exec file.
3603 (nindy_before_main_loop): Use target_load, not target_add_file.
3605 * remote-vx.c (net_load): Specify large timeout for load
3606 requests. Allow user to break out with INTERRUPT.
3607 (net_break): Remove useless code, clean up. Change callers.
3608 (parse-args, skip_white_space, find_white_space): Clean up arg
3609 parsing to cope with quoted strings.
3610 (net_wait, net_quit): Never call error, just return status.
3611 (vx_read_register, vx_write_register): Cleanup status checking.
3612 #ifdef the code based on which CPU we are using (960 or 68k),
3613 FIXME, this should be completely general but it isn't yet.
3614 (vx_xfer_memory, vx_resume): Cleanup status checking.
3615 (vx_run_files_info): Improve message.
3616 (vx_load_command): Renamed from vx_add_file_command. Allow load
3618 (net_ptrace): Remove unused routine.
3619 (vx_wait): Adopt code from vxgdb960 to cope with broken
3620 connections to target machine and prompt to disconnect. Remove
3621 debug printouts. Map some EVENT_'s to SIGnals.
3622 (add_symbol_stub, vx_open): Print names of object files we found,
3623 and "ok" if we read their symbols OK. Clarify output in general.
3624 (vx_attach, vx_detach, vx_kill): Add these commands.
3625 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3626 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3627 "info files" output, and create_inferior, since we already have
3630 * stack.c (frame_info): Replace Frame_unknown with 0.
3631 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3632 (return_command): Pop until the PC matches as well as the FP,
3633 so it works even if the FP is shared with another function,
3634 as in "frameless" or "leaf" procedures.
3636 * symfile.c (load_command): renamed from add_file_target_command.
3637 (add_syms_addr_command): renamed from add_file_addr_command.
3638 (add_syms_command): Stub to call target_add_syms.
3639 (_initialize_symfile): Change command names and descriptions,
3640 add-file => add-syms, and load from alias to its own command.
3642 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3643 maybe_kill_then_create_inferior): Default for attempts to start
3644 a process, if one is already running, is to ask about killing
3645 it and retry if yes.
3646 (upstack_create_inferior): #if-0 it, strata obsolete it.
3647 (push_target, unpush_target, pop_target): to_close() a target
3648 before unstacking it.
3649 (target_info): Renamed from target_files_info.
3650 (_initialize_targets): Rename "i files" as "i target", accessible
3653 * target.h: Improve comments about the target_ vectored routines.
3655 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3656 Convert commenting style to standard GNU style.
3657 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3658 (SKIP_PROLOGUE): No longer a no-op.
3659 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3660 (*_REGNUM): Sort register numbers.
3661 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3662 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3663 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3664 are now 10 byte extendeds, not 8 byte doubles.
3665 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3666 for nindy versus vxworks targets. FIXME, this should possibly go
3667 in the target vector.
3668 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3669 frame_saved_regs and arg pointer with each frame.
3670 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3671 (FRAME_ARGS_ADDRESS): Use cached result.
3672 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3673 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3674 (PRINT_RAMDON_SIGNAL): Call print_fault.
3675 (POP_FRAME): Now works.
3677 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3678 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3679 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3680 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3683 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3684 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3686 * valarith.c (value_subscripted_rvalue): Avoid handling
3687 floats and doubles specially; it gave alignment errors. Lint.
3689 * valops.c (value_of_variable, value_of_this): Error if unknown
3692 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3693 to avoid alignment problems.
3694 (value_print): Handle unknown value address.
3695 (cplus_val_print): Two args are ignored; remove them. Change caller.
3696 (val_print): Use unpack_long rather than pointer-deref.
3699 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3700 to avoid alignment problems.
3701 (value_being_returned): Error if return value unknown.
3702 (set_return_value): Add bogosity warning, FIXME. *
3704 * TODO: A woman's work is never done.
3706 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3707 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3708 Add ieee-float.o to OBS.
3709 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3710 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3711 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3713 Changes to generalize the VxWorks RPC protocol slightly, to handle
3714 i960 as well as 68000.
3716 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3717 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3718 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3719 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3720 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3721 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3722 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3723 so they will move in target byte order rather than network
3724 byte order (happens to be the same).
3726 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3728 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3730 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3733 Add contribution lines to various files, showing where they
3736 * breakpoint.c (break_insn, check_break_insn_size,
3737 read_memory_nobpt): Remove to mem-break.c.
3739 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3742 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3743 entry has bad register number. This change is not
3744 tested in this release, FIXME.
3746 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3749 * value.h: Force value's contents field to be aligned to hold
3750 at least a double or a long long (if supported). This avoids
3751 doing bcopy's in and out of the contents field.
3753 (step_1): Avoid coredump under obscure circumstances when we
3756 * symtab.h (misc_info): Add field to misc function vector for
3757 any kind of cached information the target code desires. AMD
3758 29000 uses this to avoid repeating examine_function_prologue's.
3760 * coffread.c: Lint. Remove static symfile, read_section_header.
3761 core.c (have_core_file_p): Lint: remove.
3762 expprint.c (print_subexp): Lint.
3763 infptrace.c, valops.c, valprint.c: lint.
3765 Roll in changes from vxgdb-5.0.1:
3767 * symtab.h: Comment byte order of each address class. Add
3768 LOC_LOCAL_ARG for frame-relative args (960).
3769 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3770 symtab.c, symmisc.c: ditto.
3772 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3774 * remote.c (remote_resume): Error if resume with a signal.
3776 * symfile.c (prim_record_misc_function): Clear misc_info.
3777 (fill_in_vptr_fieldno): Check stub type of arg.
3779 * valops.c (value_cast): Avoid looking up names of types whose
3780 name we don't know, to prevent coredump. Sun CC produces typedef
3781 rtx and the name of *rtx is zero...
3783 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3785 Roll in changes from final AMD 29000 port (Tiemann).
3787 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3788 for ../include/a.out.encap.h. This might not work now that BFD
3789 is separately compiled. Instead, BFD support for encap will have
3790 to translate machine type 29k into the right COFF_MAGIC.
3792 * infcmd.c: Remove references to inferior_pid that aren't used
3793 in actual ptrace calls; use target_has_execution, etc.
3794 (have_inferior_p): Remove function.
3795 (program_info): Print target info rather than "process number";
3796 avoid gratuitous messages unless from_tty.
3797 (run_stack_dummy, finish_command): Set proceed_to_finish.
3798 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3799 main.c: Lint. Lose have_inferior_p().
3800 inferior.h (have_inferior_p): Remove, lint.
3801 (proceed_to_finish): Add flag to ask that all regs be saved
3802 by normal_stop, for the few commands that need it, speeding up
3803 serial I/O. Add comments to stop_registers.
3805 * remote-eb.c: Remove newline from breakpoint message we grep
3806 for. Never time out when running the user program.
3810 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3812 Roll in changes from vxgdb-5.0.1:
3814 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3815 symbol in its raw form, we are processing an unlinked ".o" file.
3816 See if the target environment has assigned it an address, using
3817 target_lookup_symbol (VxWorks does), and enter it into the symtab
3820 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3821 68k versions for a simpler version that assumes zero FP at bottom.
3822 Fixes bug of truncated stack reports.
3824 * target.h (target_lookup_symbol): Define this routine's args
3825 and result, finally.
3827 * target.c (nosymbol): Default routine for target_lookup_symbol.
3828 (target_default): Default lookup_symbol and call_function too.
3829 (files_info): Only print has_all_memory warning if a non-dummy
3832 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3833 vx_convert_from_virtual): If target does not have floating point,
3834 zero register "values", and avoid doing cross-net conversions.
3835 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3836 (vx_open): Rearrange code that attaches to target and reads
3837 symbols for all loaded modules, to work if some of the modules
3838 are not accessible. Add symbol_stub() and add_symbol_stub()
3839 as callbacks from catch_errors(). Allow connect attempt to be
3840 interrupted painlessly with ^C (FIXME, there are still some bugs
3841 if the interrupt happens during symbol reading.). Print
3842 final message with puts_filtered, since symbol messages are
3847 * main.c (catch_errors): Only print errstring if non-null.
3848 (command_loop): Avoid an ioctl per command to test ISATTY.
3850 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3851 (vx_xfer_memory): Return correct result!
3852 (vx_files_info): Indicate whether target has float or not.
3853 (vx_lookup_symbol): Complain, not error, if target gone.
3854 (vx_open): Print "Connected" msg before disabling immediate-quit.
3855 [FIXME: lookup_symbol and vx_open changes need testing.]
3857 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3858 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3859 contributor lines and update copyrights to 1991.
3861 Changes from an attempted H-PUX host port:
3863 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3864 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3865 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3866 * remote-vx.c: include <sys/time.h> for HPUX.
3867 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3868 "core_file_command" routine to BFD regime. May not work yet.
3870 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3872 * xgdb.c: Replace X10 version with some VJ version.
3873 (FIXME: Its copyright assignment is not on record.)
3874 * xgdb.c: Update include files to X11R4 (Xaw crud).
3875 (xgdb_display_source, create_text_widget): fix call to
3876 get_filename_and_charpos. Rewack source window stuff for X11R4
3877 (gleaned from include files, and "nm's" of binary libraries, since
3878 I had no doc available).
3879 (append_selection, append_selection_word): Disable with FIXME
3880 since R4 changed interface here.
3881 (create_buttons): Add back the old set of buttons.
3882 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3884 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3885 Roll VERSION to 3.94 (not yet final though).
3887 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3889 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3890 obstack_int_grow, obstack_int_grow_fast): Eliminate
3891 cast on left of assignment, which gives MIPS cc fits and is
3894 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3895 F_ALIAS. Use printf, not fprintf, when not passing a file
3897 (compare_opcodes): Check that identical instructions have
3898 identical opcodes, complain otherwise.
3900 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3901 was reported by Roland McGrath.
3902 (unimp): Only match if exactly zero instruction. (Roland)
3903 (branches and traps): Generate all variations of these
3904 instructions with macros, based on a single call that defines
3905 each condition name and its binary representation.
3906 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3908 * valprint.c (val_print_fields): Take, and use, format parameter.
3909 This means that "p/x struct" again prints the elements in the
3910 desired format. Changed callers.
3912 * stack.c (frame_info): Use filtered output, and indicate wrap
3913 points. Remove kludgy formatting designed to avoid line wrap.
3915 * utils.c (wrap_here): If the line is already full (because
3916 we had printed a long indent or long wrapped string), do an
3917 immediate newline-and-indent.
3919 * m68k-pinsn.c (print_insn_arg): Bugfix from
3920 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3921 instruction is incorrectly disassembled as bkpt #8.
3923 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3924 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3925 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3926 and then will dump core (sometimes). I traced it back to an
3927 uninitialized symfile_name in psymtab_to_symtab.
3928 (const_vol_complaint): Add quotes to message.
3929 (define_symbol): Only believe line number if gcc_compiled.
3930 Avoid allocating symbol if we will not return it.
3932 Add target strata support so that newly established targets go
3933 into their right place in the target stack (e.g. a new exec file
3934 doesn't wipe out the ability to access the running process).
3936 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3937 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3938 and initialize it properly in all the targets.
3940 * target.h: Document strata. Change return type of push_target.
3942 * target.c (nomemory): new function for dummy memory access.
3943 (tcomplain): Rename complain, now also used in symfile.c.
3944 (push_target): Push targets within strata. New return value shows
3945 whether new target is on top of stack or not. Always keep dummy
3947 (target_files_info): Ignore dummy target.
3949 * core.c (core_open): Warn user, and skip accessing file, if the
3950 core target is not the topmost target in the stack.
3951 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3954 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3955 target_ops, it doesn't belong there since we have no regs there.
3956 Change name of target from machine => memory to clarify.
3958 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3960 * Freeze version 3.93 for release.
3962 * Makefile.dist: Handle vx-share and nindy-share subdirs
3963 properly when building gdb.tar.Z.
3965 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3966 printed in various places, so I could change just one copy.
3968 * dbxread.c, coffread.c: Change references to bfd->iostream
3969 to cast to FILE *, now that BFD avoids needing types defined
3970 in other header files.
3972 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3974 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3975 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3976 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3977 (actually gcc -Wall).
3979 * dbxread.c: Remove first_global_sym, last_global_sym, since
3980 they are never referenced.
3982 * defs.h (baud_rate): Declare.
3983 main.c: Define it, and add the -b option to set it.
3985 * gdb-int.texinfo: Add text on how to define a new host or target
3986 architecture, prompted by Per Bothner's questions about MIPS
3989 * gdb.texinfo: Document "complaints". Change doc of -q since
3990 gdb no longer prints the copyright and blurb if you specify a file
3991 name to be debugged (just like Emacs). Add doc for Nindy-specific
3992 command line flags for specifying target serial port and such.
3993 Update copyright to 1991.
3995 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3996 has taken over for us the job of ripping up executable files. The
3997 crud caused Per Bothner's port to not compile.
3999 * infrun.c (normal_stop): Avoid printing "Program exited
4000 normally" if we are in batch mode. This allows a GDB which
4001 executes a program on a target system, to behave like a Unix
4002 command (input from stdin, output to stdout, no extraneous
4005 * main.c (main): Allow additional machine-dependent command line
4006 options to be specified with the ADDITIONAL_OPTIONS,
4007 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
4008 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
4009 processing to occur just before the main loop with
4010 BEFORE_MAIN_LOOP_HOOK.
4011 (main): If a "core file" argument is specified, and it is not a
4012 core file, try it as a process ID to attach.
4013 (symbol_completion_function): Attempt to cope with
4014 "show screen-" TAB, not very successfully. This needs more work,
4016 (batch_file): New function, returns whether we are reading
4017 commands from an interactive tty on stdin, or from somewhere else.
4018 Called by normal_stop since it doesn't get from_tty passed down
4019 to it like many commands do.
4021 * remote-nindy.c: Handle command line options for nindy
4023 (nindy_before_main_loop): Prompt user for tty name if they
4024 don't specify it before getting to the interactive command loop.
4026 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
4027 and -r command line options. Also add hook before main loop
4028 to make it easy to specify a tty.
4030 * TODO: More things to do, one done.
4032 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
4034 * dbxread.c: Make complaint() calls pass pointer, not struct.
4035 Add complaints about badly formatted C++ type information
4036 (const/volatile indicator, and parse errors resulting in
4037 error_type). Fix C++ virtual member fn comment.
4038 (read_struct_type): Avoid bumping pointer if we got a parse
4039 error; this prevents our walking beyond the end of a string.
4040 Terminate loop on null char as well as semicolon.
4041 (process_one_symbol): Fix the LBRAC fix so that it uses the
4042 last previous SLINE, FUN, or SO record's PC address. C++ debug
4043 symbols did not have SLINE records in a useful order compared
4044 to the LBRAC records.
4045 (define_symbol): Handle "catch" records.
4047 * symtab.c (check_stub_type): Added new complain
4048 `stub_noname_complain' and added a consistency check to
4049 keep the debugger from crashing when finishing from an
4050 exception frame. A real fix will be needed later.
4052 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
4054 * infcmd.c (attach_command): Make global.
4056 * Makefile.dist (REMOTE_OBS): Make these compile by default,
4057 but make them easy to comment out. Perhaps later they should
4058 be enabled by what CPU you configure for? FIXME.
4059 (VERSION): Roll to 3.93.
4060 (pinsn.o): Remove rule for obsolete file.
4061 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
4063 Run down a problem that manifested by printing the wrong function
4064 name in stack traces of read_ofile_symtab. Turned out that the
4065 problem was the SunOS 4.1.1 (and previous) C compiler outputs
4066 the LBRAC symbol with an address in the *data* segment, which
4067 blew our binary search through the blocks.
4069 * dbxread.c: Use the complain() facility consistently to bitch
4070 about problems in the symbol file we are reading.
4071 (finish_block): Add code to check the nesting of the blocks;
4072 complain and Procrust them to fit if wrong.
4073 (make_blockvector): Check the order of the blocks, complain
4074 [but don't cope] if wrong.
4075 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
4076 symbols to be sure their PC value is greater than the last SLINE
4077 (line number) symbol we've seen, complaining and adopting the
4078 SLINE PC value if wrong.
4080 * symfile.h (struct complaint, complaint_root, complain,
4081 clear_complaints): Add.
4082 * symfile.c (complain, complaint_root, clear_complaints): Add
4083 facility to deal with non-fatal complaints and to regularize their
4085 (symbol_file_add): Clear complaint counters to allow new complaints.
4086 (initialize_symfile): Add 'set complaints' and 'show complaints'.
4088 * dbxread.c (dbx_symfile_read): Remember the address and size
4089 of the string table for the main symbol file, so we won't read it
4091 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
4092 to avoid reading the string table yet again. Lint.
4093 (throughout): Improve filtered output, including word wrap.
4094 (read_range_type): Improve Bothner's fix to handle other types too.
4096 * utils.c: Improve line wrap implementation. Handle unlimited
4097 width by making chars_per_line unsigned.
4098 (puts_filtered): New, easy, function.
4100 * defs.h (puts_filtered): add.
4102 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
4103 call the identical sort_symtab_syms() in symfile.c instead.
4105 * expread.y: Suggest the `file' command rather than `symbol-file'.
4107 * command.h (enum var_types): Add zinteger for seroable
4109 * command.c (do_setshow_command): Handle var_zinteger. Restructure
4110 nested if's into a switch.
4112 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
4113 we did not stop because of a breakpoint (it must have been for
4114 some other reason, like a "stepi"), so don't print anything.
4116 * symtab.c: Include <sys/types.h> all the time. Now that BFD
4117 doesn't include <sys/types.h>, old SunOS's require it for
4120 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
4122 A test port of gdb-3.92.6 to the Sony NEWS.
4125 Don't normally link in remote- or vx stuff.
4126 Some of it doesn't compile, and it wastes space for 99% of the users.
4127 Remove reference to no-longer-used HAVE_VPRINTF.
4128 Fixed BFD_DEP typo to BFD_DIR.
4130 Fix cast in arg to bfd_h_getlong.
4131 Make char *prefix be const.
4132 Fix how certain range types are mapped into builtin unsigned int types.
4134 Remove 2 #includes. They cause errors (on Sony, at least),
4135 and aren't needed (they wern't in earlier versions).
4137 print_address_symbolic should never demangle labels
4138 (since it prints *assembler-level* labels).
4140 [This was superseded by the change to printcmd below.]
4143 Add some "volatile" return types to avoid warnings.
4144 If MISSING_VPRINTF add vprintf function and not just macro
4145 (since vprintf is used in printcmd.c).
4147 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
4148 (The latter isn't grokked by some PCC-based compilers.)
4150 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
4152 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
4153 * nindy-share/coffstrip.c
4154 Added some forward declarations (otherwise, gcc complains
4155 about implicit extern redefined as static).
4157 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
4159 Changes inspired by Per Bothner:
4160 * printcmd.c (print_address_symbolic): Take additional parameter
4161 specifying whether to demangle.
4162 (print_address): Pass in asm_demangle to control demangling.
4163 (print_address_demangle): New fn, takes explicit arg to control
4165 * utils.c: Add new vars demangle and asm_demangle, and let them
4167 (fputs_demangled): If !demangle, just print the argument.
4168 (fprint_symbol): If !demangle, just print raw symbol.
4169 * valprint.c (val_print): Call print_address_demangle rather than
4170 print_address, to cause demangling to depend on the global
4171 rather than assembler-level demangling setting.
4172 * WHATS.NEW, gdb.texinfo: Document.
4174 * main.c (show_command): Show all settings if no arg.
4175 (initialize_main): Make "info set" the same as naked "show".
4176 * command.c (cmd_show_list): Handle prefix commands in the
4177 list, and print the name of the setting as well as its English
4178 description and value.
4180 Allow gdb functions to specify where a line should wrap if it
4181 exceeds the size of a terminal line. Use it to make the output
4183 * utils.c (set_screen_width_command): New fn, mallocs a buffer
4184 of the right size when screen width changes.
4185 (set_screensize_command, screensize_info): Remove #if 0'd fns.
4186 (wrap_here): New fn, indicates a point in the output where we
4187 should wrap the line rather than just letting it overflow at a
4189 (fputs_filtered): Implement wrapping.
4190 (n_spaces): New fn, returns a pointer to N spaces.
4191 (print_spaces_filtered): Use n_spaces.
4192 * defs.h (n_spaces): Declare.
4193 * stack.c (print_frame_info): Wrap with 4-space indent after
4194 fn name and before filename and line number.
4195 * printcmd.c (print_frame_args): Wrap with 4-space indent
4196 before each argument name is printed.
4197 * valprint.c (value_print): Wrap with no indentation before
4199 (val_print_fields): Wrap with indentation relative to nesting
4200 level before each field name.
4201 (val_print): Wrap with nesting indentation before array elements.
4202 * command.c (do_setshow_command): Avoid extra newlines,
4203 wrap with 4-space indent around values printed, end with period.
4204 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
4206 * breakpoint.c (breakpoint_1): Implement addressprint for
4207 "info breakpoints" display. Change file name and line number
4208 format to " at file:nnn" rather than " (file line nnn)".
4209 * gdb.texinfo: Document.
4212 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4214 Frozen for gdb-3.92.6 release.
4216 README, WHATS.NEW: Update for 3.92.6 release.
4218 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
4219 coffread.o from configs since it is now built by default.
4220 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
4221 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
4222 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
4223 from configs since it is now built by default.
4225 Makefile.dist: Update for release 3.92.6. Handle files that
4226 have been moved to ../include, ../getopt, or ../bfd. Add
4227 saber.suppress and tests directory. Add config.status to
4228 the release (it will say "none").
4230 coredep.c: Minor formatting fixes.
4232 These changes were made in early December but only checked in now:
4233 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4234 nindy-share/nindy.c: lint
4235 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4236 register values coming back from the target; we store values
4237 in target byte order everywhere.
4239 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4241 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4243 * valprint.c (cplus_val_print, val_print_fields): New functions,
4244 which print C++ objects. They conspire to avoid printing a
4245 virtual base class more than once, following all the twists and
4246 turns of C++ virtual base rules.
4247 (val_print): Call the above rather than do it by hand.
4249 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4250 symbol file, not for added files like shared libs. This really
4251 needs to be generalized to a timestamp per file.
4253 * core.c (cleanup_core): Avoid coredump if no core file.
4255 * config.gdb: Accept -host or -target in place of +host or
4258 * coffread.c (find_linenos): Avoid desupported BFD interface
4259 to line numbers. We still read them manually rather than using
4260 BFD's "generic" features.
4262 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4264 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4266 * Makefile.dist: Eliminate use of $< in explicit targets.
4268 * readline/Makefile: Use $< rather than $*.c, which does not
4269 include the VPATH in GNU Make.
4271 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4272 copies of tconfig/i960, added for global configuration
4273 compatability. All i960 versions can read both coff and b.out.
4275 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4276 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4279 * TODO: Think of more things to do.
4281 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4283 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4284 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4285 64-bit float conversion.
4287 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4288 equivalent to sun?os4 so global config works.
4290 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4292 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4294 * main.c: Only declare linesize once; declare pagesize not at
4295 all, since it is never used.
4296 (main): Clear newly allocated line before it is used.
4298 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4300 Further stabilization for the Intel 960.
4302 * Makefile.dist: Parameterize the location of the "include"
4303 and "bfd" directories, as well as "getopt". Add symfile.c.
4304 Link in both dbxread and coffread. Fix up "make depend" to
4305 rewack the locations of include, bfd, and getopt in its output.
4307 * README: Document moving include files, improve some of
4310 * coffread.c: Move common code out to symfile.c. Change
4311 symbol_file_command style interface to use new *_symfile_init
4312 and *_symfile_read interface under BFD. Use BFD internal
4313 info to locate line table, symbols, etc.
4315 * core.c (core_fetch_registers): Rename to get_core_registers
4316 to avoid confusion with fetch_core_registers.
4317 (register_addr): Move to coredep.c, which is already machine
4318 dependent. This leaves core.c pretty clean of dependencies.
4320 * coredep.c (register_addr): Accept this routine from core.c.
4322 * dbxread.c: Move common code (with coffread.c, etc) into new
4323 symfile.c. Each psymtab now contains a pointer to the
4324 format-dependent function that knows how to read it in. Make
4326 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4327 (process_one_symbol): Add code to complain about a "compiler bug
4328 we muzzle here", if we actually see it.
4330 * eval.c (evaluate_subexp): Insert missing "break" statements
4331 in code that determines whether a variable is an lvalue in
4332 memory, register, or whatever. I detected this via a compiler
4333 bug in which it *almost* mashed out the whole switch statement.
4335 * gdb-int.texinfo: Add minor sections on configuring gdb for
4336 release, and about the README file.
4338 * infcmd.c (registers_info): Fix formatting somewhat. Still
4339 not as pretty as before, but it handles byte swapping.
4341 * remote-nindy.c: If data cache routines are interrupted while
4342 waiting for the remote end, be sure that any uninitialized cache
4343 blocks are on the free list, not on the valid list!
4345 * symfile.h: Flesh out this header file with all the various
4346 routines and variables that have been merged in from dbxread.c
4347 coffread.c, and symtab.c to symfile.c.
4349 * symfile.c: New file, containing code common to dbxread.c,
4350 coffread.c, and some code from symtab.c. All generic code for
4351 reading symbol files should be in here now.
4352 (unrecord_misc_function): Remove unused function.
4354 * symtab.h: Remove file-reading things to symfile.h.
4356 * symtab.c: Remove file-reading things to symfile.c.
4358 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4359 to decode i960 fault types.
4361 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4362 target.c: Change type of the "resume" function from int to void,
4363 since its result was never used.
4365 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4367 * main.c: Replace "stupid" with "caution"; you now "set caution
4370 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4372 * infcmd.c (do_registers_info): Call val_print to deal with the
4373 byte order of the registers being printed. FIXME, this makes
4374 the formatting of the output uglier.
4376 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4377 defined, call it for signals the debugger doesn't itself use.
4378 The i960 uses this for more detailed fault information.
4380 * remote.c (remote_open): If arg is null, print help rather than
4383 * sparc-xdep.c (register_valid): Avoid declaring size, since
4384 various modules will think of various sizes depending on the
4385 architecture of their tm-file. FIXME, we need protection against
4386 actually entering one of those modules, which would clobber
4387 storage if not for the target architecture compiled into gdb.
4389 * stack.c (up_command, down_command): Always print the frame
4391 (up_silently_command, down_silently_command): New commands
4394 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4396 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4397 more parameters than it used to.
4399 * findvar.c (registers): Increase slop to 256 bytes, which should
4400 protect us against even most RISC machines with large register
4402 (locate_var_value): Move declaration inside related ifdef.
4404 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4405 throughout, to avoid throwing away buffered input from the board.
4406 (nindy_wait): Supply_register takes addr_of_value, not value.
4407 (i960_print_fault): Renamed from i80960_fault.
4408 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4409 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4411 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4412 we can set the PC in the call to proceed(). Unpush nindy_ops
4413 before pushing it on top, to avoid message to user. Eliminate
4414 commentary from Unix machines that just misleads here.
4415 (reset_command): Fix error message to suggest target command.
4417 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4419 Release 3.92.5 as frozen.
4421 Stabilize the merged release...with help from lint, Saber C,
4424 Everywhere: Add include files needed to declare return types
4425 of functions called.
4427 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4429 * breakpoint.h: Add undeclared breakpoint functions, and some
4430 functions for display handling since I couldn't think of a better
4433 * breakpoint.c (insert_breakpoints): Make code for disabling
4434 shared library bkpts more likely to work. It's used when we
4435 rerun a program and stop before the shared library has been
4437 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4438 cast from pointer, so it squeezes through catch_errors.
4439 (bpstat_stop_status): Fix logic broken some time ago. We now
4440 always create a bpstat if the stop address matches a breakpoint,
4441 even if we don't stop there -- just like the old code used to do
4442 before I got my fingers into it (sigh).
4443 (breakpoint_1): Print "ignore count" after "stop only if"
4444 condition, since that's how it actually works.
4445 (mention): Handle watchpoints as well as breakpoints.
4446 (watch_command): use set_raw_breakpoint and mention to do most
4447 of the work (and initialize all the fields!). Only pass one
4448 arg to parse_c_expression, since that's all it takes.
4450 * command.c (not_just_help_class_command): Rename arg to args
4451 since we ignore "unused argument" warnings on vars named "args".
4452 inflow.c (child_terminal_info): ditto.
4453 infptrace.c (kill_inferior): ditto
4454 main.c (catch_errors, version_info, quit_command, pwd_command,
4455 source_command, dump_me_command, editing_info,
4456 set_history_size_command, set_history, show_history,
4458 stack.c (locals_info): ditto
4459 target.c (target_files_info): ditto
4460 valprint.c (set_input_radix, set_output_radix): ditto
4462 * core.c: Remove old variables for handling core and exec file
4463 sections (data_start, data_end, stack_start, stack_end,
4464 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4465 text_end, exec_data_start, exec_data_end, text_offset,
4466 exec_data_offset, data_offset, stack_offset). They're
4467 superseded the more general build_section_table and
4469 (get_exec_file): Mention the `file' command.
4470 (read_memory_check): Rename to memory_error, and only call it
4471 in the case of an actual error.
4472 (read_memory, write_memory): call memory_error.
4473 (core_fetch_registers): Register section name is ".reg".
4475 coredep.c: Remove a bunch of crud now that all this file does
4476 is pull the registers out of a core file.
4477 (fetch_core_registers): Rewrite to actually work, I hope.
4479 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4480 Replace index() with strchr(). Remove all the pre-BFD macro
4481 definitions for accessing the symbol file.
4482 (struct dbx_symfile_info): Encapsulate the information that
4483 dbx_symfile_init needs to pass to dbx_symfile_read in this
4486 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4487 dbx_symfile_discard): Rearrange symbol file reading to divide
4488 the format-specific part from the format-independent part,
4489 leaving the format-independent part such as file name expansion
4490 and opening in symtab.c. This replaces
4491 partial_symbol_file_open and partial_symbol_file_read.
4492 Symbol_file_read, add_file, add_file_target_command,
4493 add_file_addr_command move to symtab.c. Pass an explicit
4494 "mainline" flag for when reading the main symbol table, rather
4495 than relying on the offset address to be zero or nonzero.
4497 (dbx_symfile_read): Don't allow void *'s to be printed as
4499 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4500 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4501 macro" debug version really work.
4502 (read_dbx_symtab): Remove unref'd parameter inclink.
4503 Avoid swapping N_SLINE symbols, for speed.
4504 Merge N_TEXT!N_EXT case with the other external symbol
4505 definitions' case. Add comments.
4506 (start_psymtab): Allocate the symfile name in the psymtab on
4507 the psymbol_obstack, rather than using the caller's storage.
4508 (end_psymtab): Only allocate a dependencies list if there are
4510 (psymtab_to_symtab_2): Use BFD when reopening file to read
4511 its symbols for real.
4512 (read_struct_type): Add FIXME comments where it needs work
4514 (read_huge_number): Add FIXME about overflows.
4515 (read_range_type): Add FIXME about comparing a long to 1<<32.
4517 * coffread.c: Minor changes to move things closer to the new
4518 regime with symtab.c and dbxread.c Major work is still needed
4521 * exec.c (exec_file_command): Remove old variables (see core.c
4523 (xfer_memory): If memory transfer is right at the end of a
4524 section, don't lose.
4526 * findvar.c (get_saved_register): If value is in a real
4527 register, LVAL is lval_register, not lval_memory.
4529 frame.h: Declare print_sel_frame and record_selected_frame.
4531 gdb-int.texinfo: New file, for GDB internals documentation.
4532 Very simple, unformatted doc of cleanups is there for now.
4534 gdbcore.h: Remove obsolete variables that described a.out
4535 section addresses and offsets. (See core.c above.)
4536 Declare fetch_core_registers and registers_fetched.
4538 getopt.c: Declare char *alloca(); even on SPARC.
4540 infcmd.c (run_command): Call target_kill rather than
4542 (step_command, next_command, stepi_command, nexti_command):
4543 Declare from_tty parameter even though we don't use it.
4544 (run_stack_dummy): argument BUFFER is a char array, not
4545 a pointer to REGISTER_TYPE.
4546 (finish_command): using_struct_return needed a value *,
4547 not a struct symbol *.
4549 * infptrace.c (child_xfer_memory): To avoid dependency on
4550 where sections are in memory, try PT_WRITE_D and if that fails,
4551 try PT_WRITE_I. Most Unixes don't care which you use.
4553 * infrun.c (step_resume_break_shadow): Change to array to
4554 match other breakpoint shadow storage.
4555 (clear_proceed_status): Pass address of bpstat to
4556 bpstat_clear, not the bpstat itself.
4557 (child_create_inferior): FIXME comment about if the child
4559 (start_inferior): Remove old function.
4560 (child_open): Use target_kill rather than kill_inferior.
4561 (wait_for_inferior): Ditto.
4562 (insert_step_breakpoint, remote_step_breakpoint): Use
4563 new step_resume_break_shadow.
4565 * inftarg.c (child_wait): If all child processes die,
4566 pretend that the one being waited for exited with signal 42.
4568 * main.c (command_line_input): When scanning for comments,
4569 don't coredump on unclosed quotes.
4570 (quit_command): Use target_kill rther than kill_inferior.
4571 (_initialize_main): Rename class_user from "user" to
4574 * printcmd.c (print_command_1): Initialize "fmt" if no format
4575 is specified by the user.
4576 (print_frame_args): Only add to args_printed if we are
4577 actually fetching args from the stack (avoiding undefined
4579 (_initialize_printcmd): Remove bogus \{ from string.
4581 * remote-eb.c (eb_open): Avoid coredump on no argument.
4583 * remote-nindy.c: Bring out of Intel environment into new
4584 target environment. Remove all conditional compilation on
4585 I80960. Massive hacking throughout.
4586 (nindy_xfer_inferior_memory): New routine stolen from
4588 (nindy_create_inferior): New routine pieced together, probably
4589 not quite working yet.
4590 (nindy_ops): New target_ops struct for nindy.
4592 * remote-vx.c: Use write_memory rather than target_write_memory
4593 to get error checking.
4594 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4596 (vx_create_inferior): Use target_terminal_ours...
4598 * signame.c (_initialize_signame): Always initialize, since
4599 we need the table for things other than psignal.
4601 * solib.c (solib_add): Use symbol_file_add, not add_file.
4602 (solib_address): Return boolean result rather than struct
4603 pointer which nobody else knows the type of.
4605 * sparc-tdep.c, valops.c: Use write_memory rather than
4606 target_write_memory, to get error checking.
4608 * stack.c (locals_info, catch_info, args_info,
4609 get_selected_block, frame_command, up_command): Use
4610 target_has_stack, rather than have_inferior_p or
4613 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4615 * symfile.h: New file, defining the interface between the
4616 generic and object-file-specific symbol reading code.
4618 * symtab.c: Move generic symbol-reading interface to symtab.c,
4619 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4620 table to map BFD targets to symbol-reading modules in GDB.
4621 Change index to strchr.
4622 (lookup_struct_elt_type): Use error() rather than hand-made
4623 simulations thereof.
4624 (lookup_partial_symbol): Speedup slightly when length == 0.
4625 (symbol_file_add): New function.
4626 (symbol_file_command): Call it.
4627 (symfile_open, symfile_init): New function.
4628 (add_file_target_command, add_file_addr_command): moved from
4631 * target.c (target_command): use target_kill.
4633 * target.h (target_files_info): Don't declare, never called
4636 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4637 files to determine stack end address.
4639 * valarith.c (value_x_binop, value_x_unop): Change error message
4640 to be more useful. Pass proper argument to value_struct_elt.
4642 * valops.c (value_assign): FIXME comment that long long
4643 bitfields will break here.
4645 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4646 Update `make saber_gdb' to work better.
4648 * TODO: A woman's work is never done.
4650 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4651 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4652 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4653 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4654 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4655 valops.c, valprint.c, exec.c: Lint.
4658 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4660 Continuing Intel 960 port merge of GDB.
4662 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4663 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4664 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4665 Wack over "make depend" so it handles files in subdirectories
4666 vx-share, nindy-share, bfd, and in the current directory.
4668 * blockframe.c (get_prev_frame_info): Remove fatal error
4669 if stack not defined.
4671 * core.c (core_open, core_detach): New functions that handle
4672 the old "core-file" command as "target core" and "detach" instead.
4673 (core_file_command): Call them.
4674 (core_xfer_memory): Use common routine xfer_memory.
4676 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4677 dbxread now uses bfd for everything but symbol reading itself.
4678 BFD internals are used to drag out the relevant file offsets.
4679 (partial_symbol_file_open): Change args all around for BFD.
4681 * symtab.c: Rename "value" to "val" everywhere, so we can
4683 (symbol_file_command): New command, moved from dbxread.c
4684 and coffread.c. It uses BFD to read the file, then vectors
4685 based on its type, to dbx or coff symbol readers.
4686 * symtab.h: Extern a few vars for symbol_file_command.
4688 * target.h: Breakpoint takes a char * save area, not a char **.
4690 * valprint.c (val_print): When unpacking bitfields, offset
4691 the address in gdb of the value, if it is declared with a shorter
4692 type. Remove the last "runtime kludge test" of host byte order.
4694 * utils.c: Remove old my_bfd_read routine.
4696 * stack.c (frame_info): Use target_has_stack. Print program counter
4697 register's actual name rather than "pc", since it's called the
4698 "ip" (instruction pointer) on the i960 (sigh).
4700 * target.c (target_command): Add command for selecting a target
4701 type and calling its open routine. This is used for initiating
4702 communication with a particular target, in a generic way.
4704 * tm-i960.h: Update for modern gdb. Remove semicolons from
4705 various macros. Handle reading struct return convention, and
4706 error-out attempts to return structs with the "return" command.
4707 Be sure gdb doesn't think we know how to call functions in the
4710 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4711 to i960_xxx in lower case.
4712 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4713 not being defined yet.
4715 * remote.c (remote_open): Call start_remote to initialize
4716 wait_for_inferior during open.
4717 (remote_xfer_inferior_memory): Return length written rather
4720 * remote-vx.c (target_command -> vx_open): Use new generic
4722 * remote-eb.c, inftarg.c, exec.c: ditto.
4724 * infrun.c: Fix comments.
4725 (attach_program -> child_open): Use new generic target command.
4726 (wait_for_inferior): Clear saved register values before target_wait,
4727 so target_wait can set some of them if convenient.
4729 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4730 Return success indicator, not void.
4731 (child_xfer_memory): Avoid fetching initial word if we'll
4732 overwrite it anyway.
4734 * infcmd.c (attach_command): Use new generic target open routine.
4735 (_initialize_infcmd): Update doc on attach and detach commands.
4736 (do_registers_info): Merge in a byte-order problem as a FIXME
4739 * findvar.c (find_saved_register): Avoid problem in current frame.
4740 (read_relative_register): Ditto.
4741 (write_register): Convert byte order on the way out.
4743 * exec.c (file_command): Add.
4744 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4745 (xfer_memory): Common function between core_xfer_memory and
4747 (exec_xfer_memory): Use it.
4749 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4751 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4752 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4753 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4755 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4757 Merge Intel 960 port of gdb, continuing...
4759 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4760 symbol_file_command): Pass from_tty arg to hush 'em up.
4762 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4763 Add magic numbers for 960 COFF format.
4765 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4767 Merge Intel 960 port of gdb, from Intel "1.2" release.
4769 CHANGE_LOG entries from their port, which was based on
4772 Thu Sep 6 11:02:22 PDT 1990
4773 Remove temp file if download is interrupted.
4775 Wed Aug 1 09:08:33 PDT 1990
4776 Now uses binary protocol to talk to NINDY.
4777 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
4778 Times out after 5 seconds when trying to talk to NINDY.
4780 Tue May 29 12:54:49 PDT 1990
4781 Added variable baud rate (-b switch).
4782 Source code reorganization.
4784 Thu Apr 26 11:09:55 PDT 1990
4785 More cleanup of batch mode; specifically, execute "-s", "-e", and
4786 "-se" switches as soon as they are encountered on the invocation line.
4788 Fri Apr 20 13:47:15 PDT 1990
4791 Thu Apr 19 09:54:28 PDT 1990
4792 Add 'reset' command.
4794 Wed Apr 18 09:48:07 PDT 1990
4795 After opening remote tty, wait for 1 second to go by without input
4796 from it before trying to talk to NINDY (fixes problems with the
4797 Heurikon HK80/V960E).
4799 Mon Apr 4 16:33:05 PDT 1990
4800 Some output was not being suppressed in 'batch' mode.
4802 Thu Mar 22 15:31:11 PST 1990
4803 Ask user if old symbol table should be deleted when new file is
4806 Allow user to run a program downloaded before gdb960 was brought up.
4808 Correct "exec-file" help message for i80960 context.
4810 Correct bug in calculating user space address: could occasionally
4811 corrupt user program.
4813 Make sure to zero low-order bits in rip's because of bug in 960CA
4814 A-step part: could cause operation faults when "next"ing across
4817 Correct bug that made it impossible to get source line numbers for
4818 code loaded at addresses higher than 0x7fffffff.
4820 Wed Jan 10 12:43:22 PST 1990
4821 Open remote tty for exclusive use.
4823 Fri Jan 5 12:14:42 PST 1990
4824 Correct disassembly (CA manual was right after all):
4825 opcode for sysctl is 0x659
4827 Mon Oct 23 12:03:04 PDT 1989
4828 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4830 Mon Oct 16 14:15:09 PDT 1989
4831 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4833 Mon Oct 2 15:56:31 PDT 1989
4835 Added 960CA disassembly support.
4837 To simplify maintenance:
4838 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4840 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4841 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4842 - made disassembly interface identical to that in gdmp960.
4846 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4848 * target.h: Allow targets to stack. Add target_has_memory,
4849 _registers, etc. Restructure memory access and "info files"
4850 to walk the target stack.
4851 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4852 target.c: Change tables to match target.h.
4853 * inflow.c (child_mourn_inferior): pop child_ops.
4854 (generic_mourn_inferior): Use new has_stack flag.
4855 * infptrace.c (child_xfer_memory): New memory regime.
4856 * inftarg.c (child_files_info): New "info files" regime.
4857 * remote-eb.c: New memory regime, new info files.
4858 * remote-vx.c: New memory regime, new info files. Now use
4859 separate targets for VxWorks attachment to machine, and
4860 actually running a process under VxWorks, since one has
4861 stack & execution & regs and the other doesn't.
4862 * remote.c: New memory regime, new info files.
4863 * sparc-xdep.c (fetch_core-registers): New memory regime.
4864 * target.c: New routines and support for stacked targets,
4865 new memory regime, new info files regime.
4868 Generalize section handling for an arbitrary number of sections,
4869 including use of the new BFD (binary file) library.
4870 * gdbcore.h: Add struct section_table.
4871 * exec.c (build_section_table): Iterate all sections and
4872 record what gdb needs to know about them.
4873 (exec_command): Use it.
4874 (exec_xfer_memory): Use the table.
4875 (exec_files_info): Print the table.
4876 * core.c (core_file_command, core_xfer_memory, core_files_info):
4878 * source.c (find_source_lines): Use bfd_get_mtime.
4879 * dbxread.c: Quick changes to make it compile with new BFD.
4880 * utils.c (error): Avoid using bfd_error in generic routines.
4882 * core.c (core_fetch_registers): Get from the ".regs" section of
4884 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4886 * inferior.h (attach_flag): Export.
4887 * infcmd.c (run_command): use new target_create_inferior.
4888 * infrun.c (child_create_inferior): Don't return result.
4889 * Makefile.dist (VERSION): 3.91.4.
4891 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
4893 * breakpoint.c (bpstat_num): Handle breakpoints which have
4894 since been deleted, such as temporary breakpoints.
4895 infcmd.c (program_info): ditto.
4897 * core.c (core_file_command): Display the frame where the core
4902 * remote-vx.c (target_command): Merge in target command from
4903 targ-vx.c. A few other cleanups.
4905 * TODO, Projects: Lots more stuff to do...
4907 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4909 Massive changes to wall off the remote-debugging interface
4910 behind a function vector. The port to handle VxWorks targets
4911 is also part of this.
4913 All files: Replace references to renamed functions,
4914 remove references to remote_debugging, remove references to
4915 have_include_file, have_core_file in favor of target_has_stack,
4916 target_has_memory, etc.
4918 * Modularize the breakpoint interface.
4919 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4920 a breakpoint instruction.
4921 breakpoint.c: struct breakpoint's shadow_contents now sized as
4923 (insert_breakpoints): Vector to target to install breakpoints.
4924 (remove_breakpoints): Vector to target here too.
4925 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4926 sparc-tdep.c (single_step): Use new breakpoint interface for
4927 the single-step breakpoints.
4928 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4929 New file, contains routines to insert and remove breakpoints by
4930 reading out the old contents and later replacing them. This is
4931 how ptrace breakpoints work, and many remote systems as well.
4933 * tm-vxworks68.h: New config file, overrides a few things for
4934 Wind River's preferences.
4936 * target.h: New file, for transfer vector used to talk to the
4937 inferior (child, attached, core, exec, remote, etc). All accesses
4938 to the thing being debugged should come through these vectors.
4939 target.c: New file, routines to handle transfer vector.
4940 (various files): Add transfer vectors XXX_ops for the various
4941 targets and pseudo-targets (core files, etc) we support.
4943 * breakpoint.c (bpstat_stop_status): Further explorations of
4944 watchpoints and why things don't work all the time.
4945 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4947 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4948 the local gdbinit if it doesn't already have it.
4950 * core.c (core_ops): add and install.
4951 Allow core debugging without exec file.
4953 * dbxread.c (free_and_init_header_files): Merge two fns.
4954 (end_symtab): Free named symbol table when a new version comes in.
4955 (read_dbx_symtab): Relocate all kinds of symbols with base
4956 address. First step toward handling different text, data, bss
4958 (add_file_addr_command): Renamed add_file_command.
4959 (add_file_command): Vector to remote handler.
4960 Add "load" as an alias for "add-file" command.
4962 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4963 non-returning functions.
4965 * exec.c: Add exec_ops, and push it as a target when an exec
4968 * infcmd.c (run_command): Pass executable file name and arg list
4969 separately when starting an inferior. Permit "run" when no exec
4970 file is specified, for VxWorks.
4971 (detach_command): Move to child_detach in inftarg.c.
4973 * inftarg.c: New file. Unix-child-specific routines, and the
4974 child_ops structure.
4976 * inferior.h (registers): Export "registers" as the way for
4977 target dependent register handlers to find gdb's local copy of
4978 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4979 since it is now used by places that want wait_for_inferior to
4980 handle the grunge but want to see every trap from the inferior.
4982 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4983 Eliminate remote_debugging hooks in terminal handling.
4985 * infrun.c: Replace start_inferior with child_create_inferior.
4986 Move all the hair of Unix shells and ptrace idiosyncracies into
4987 child_create_inferior, so remote handlers don't have to deal.
4988 Remove running_in_shell. Rename stop_after_attach to
4989 stop_soon_quietly, and use it in a few other places where we want
4990 to just call wait_for_inferior and get control back on the first
4991 trap. trap_expected now never takes a value > 1.
4992 (init_wait_for_inferior): Initialize static vars when a new
4995 main.c (gdbinit): Add new hook for .gdbinit file name, let
4996 it be overridden by config files as GDBINIT_FILENAME.
4997 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4998 Both of these are used for VxWorks gdb.
5000 mcheck.c: rename include file "gmalloc.c" to avoid problems
5001 with system include file "malloc.c".
5003 param-no-tm.h: New include file, same as param.h but does not
5004 include the default "tm.h" file. This is used in files where
5005 the target is known, e.g. remote-eb.c or sparc-xdep.c.
5007 param.h: Now just a shell that includes tm.h and param-no-tm.h.
5009 remote-vx.c: New file, VxWorks remote debugging support. Uses
5010 RPC routines that are shared with the target system, in directory
5013 remote.c: Vectorize remote interface.
5015 source.c: Globalize source_path, and make an alias "l" for "list"
5016 since we now have the "load" command.
5018 sparc-xdep.c: Use new param-no-tm.h.
5020 symmisc.c (free_named_symtab): Add new function from Wind River.
5021 However, ifdef it out for now while we think about what it should
5024 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
5026 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
5027 non-Unix-children handle this with their own code in the target
5030 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
5031 source and target lists. Add vx-share to default list of include
5032 directories. Add new files to src and target lists: mem-break,
5033 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
5034 ${srcdir} versions of munch and createtags are used.
5036 * valops.c (find_function_addr): Split out of call_function.
5037 (call_function_by_hand): Rename call_function; this function
5038 calls functions in the target by laboriously patching the target
5039 word-by-word with the right stack, args, regs, etc.
5042 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
5044 Handle AMD 29000 a bit better.
5046 * remote-eb.c (readchar): Mask received char log to make it readable.
5047 (remote_start): Pass arguments down to executing program.
5048 Make startaddr unsigned.
5049 infrun.c (start_inferior): Accept args, pass them to
5051 infcmd.c (run_command): Pass args down to start_inferior.
5053 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
5054 the target object file format.
5055 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
5057 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
5058 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
5060 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
5062 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
5063 * TODO: We did a few things, we have more to do though.
5065 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
5066 * inflow.c (inferior_died): Clear deferred stores.
5068 * Debug problems with dummy frames and calls to the inferior.
5069 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
5070 * sparc-tdep.c (do_restore_insn): Simplify.
5071 (sparc_frame_find_saved_regs): Simplify and fix what we find.
5072 (sparc_push_dummy_frame): Simplify and fix what we push.
5073 (sparc_pop_frame): Slightly more hair here, deciding whether
5074 we are restoring a saved PC or returning to a return address in %i7.
5075 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
5077 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
5078 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
5079 * obstack.h (chunkfun): ditto.
5080 * defs.h (xmalloc, xrealloc): ditto
5082 * utils.c (quit): Grab the terminal from the child if necessary.
5084 * inflow.c (term_status_command): Rename to term_info, change
5087 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
5088 (is_delayed_branch): Speed up.
5089 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
5090 Still missing some float ops, and needs testing.
5092 * Support for input and output radixes other than base 10
5093 * defs.h (input_radix, output_radix): Declare.
5094 * expread.y (yyparse, parse_number): Handle changes of input
5095 radix, and ambiguous names-or-numbers in radixes >10.
5096 * printcmd.c (print_scalar_formatted): Print formatted hex
5097 numbers in varying column widths.
5098 * valprint.c (val_print): Use output_format to print scalar ints.
5099 (set_input_radix, set_output_radix, set_radix): Create.
5100 (set_output_radix): Set output_format from output_radix.
5101 (_initialize_valprint): add `set radix' but leave the others off.
5103 * main.c (execute_command): Let stupid questions be turned off.
5104 (_initialize_main): Handle "set stupidity", etc.
5106 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
5107 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
5109 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
5111 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
5112 bfd stuff is still screwed up, but with some manual work, it
5115 * breakpoint.c (bpstat_do_actions): Start over if a command
5116 proceeds the inferior, since the inferior will have stopped and
5117 will need to have its new stop-actions taken care of.
5119 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
5120 compiler fits, simplify it.
5122 * gdb.texinfo (directory command): Doc new dir command.
5123 source.c (directory_command): "dir" now puts things on the front
5124 of the path, moves dups up front, and handles multiple names
5125 on the command line, inserting each one in order. It also
5126 blows away cached line and full_filename info.
5128 * stack.c (backtrace_command): Skip "more stack frames follow"
5131 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
5132 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
5133 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
5134 The only odd one was Gould NP1, which had defined vprintf to
5137 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
5138 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
5139 variable, inspect_it.
5140 valprint.c (print_string, val_print): Use the global inspect_it
5141 to indicate whether to print in Epoch style or normal style.
5143 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
5145 * printcmd.c (call_command): add an alias for the "print" command
5146 which runs expressions and doesn't print the result if void.
5147 (print_command_1): implement it.
5149 * command.c: Remove #if 0'd code. Initialize all the fields
5150 in add_cmd (). Rename do_nothing_command to
5151 not_just_help_class_command, and make it externally visible.
5152 command.h: add user_commands to struct.
5153 * main.c (define_command): Don't overload c->function with a char
5154 string as well as a function pointer.
5156 * eval.c (evaluate_subexp): Reinstall tiemann changes to
5157 calling convention of value_struct_elt () that got dropped in
5160 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
5161 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
5163 * tm-sparc.h (POP_FRAME): replace some constants with defines.
5165 * sparc-xdep.c (store_inferior_registers): defer stores to regs
5166 until a good time (e.g. when we are about to run the child),
5167 saving ptrace calls.
5168 * infrun.c (proceed): handle DO_DEFERRED_STORES.
5169 * tm-sparc.h: define DO_DEFERRED_STORES.
5171 * sparc-xdep.c (store_inferior_registers): when storing float
5172 registers, don't store stack regs too. When storing the SP,
5173 however, DO store the stack regs too. This fixes a bug in which
5174 the dummy frame is not recognized when a call_function finishes,
5175 because its frame pointer (in the stack regs) was never
5177 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
5178 even though we don't know how to read them from an inferior.
5179 valops.c (call_function): Comment about storing SP.
5181 * infrun.c (save_inferior_status): Save away the original bpstat
5182 chain so it can be restored later. Install the copied version for
5183 use by whoever saved the status. It will be blow away by
5184 restore_inferior_status, and the original chain restored. This is
5185 important for people who have pointers into the original.
5187 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
5188 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
5189 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
5192 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
5194 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
5195 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
5196 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
5198 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
5200 * Merge Mike Tiemann's multiple inheritance changes from Sun.
5201 Store the baseclasses in a type struct starting from array element
5202 0 rather than from the unusual array element 1.
5204 dbxread.c: the above.
5205 (virtual_context): Add
5206 Read new debug information about which virtual function table
5207 a virtual function is from, and store it in fn_field.fcontext.
5209 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
5210 TYPE_FN_FIELD_STATIC_P.
5212 symtab.c: the above.
5213 valops.c: the above. Handle pointer casts of object *'s.
5214 (search_struct_method): Add.
5215 (value_struct_elt): First arg is now a pointer to a value, and is
5218 valprint.c: the above.
5219 values.c (value_virtual_fn_field): Add type arg. Handle
5220 offsetting to the proper object when calling virtual fns.
5222 (baseclass_addr): Add valuep arg.
5224 * README: Document the current state of BFD config (missing).
5225 * TODO, ChangeLog, Makefile.dist: Roll version.
5226 * WHATS.NEW: Add summary of changes since 3.5.
5228 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
5230 * dbxread.c (read_struct_type): Clear bit vectors whenever
5232 symtab.c (B_CLRALL): define.
5234 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5235 using == rather than =. Huh... This fixes the dreaded problem
5236 wherein builtin_type_int becomes TYPE_CODE_FLT.
5238 * core.c (info_files): Show the inferior pid.
5240 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5241 already knows how to look in the source directory.
5243 * Remove psymtab hair from many places. Remove duplicated code
5244 for searching symbol tables. Hide psymtabs from most places.
5245 Make it fast to get from a psymtab to its symtab.
5247 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5248 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5249 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5250 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5251 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5252 new symtab completely. New psymtabs get symtab pointer
5253 initialized to zero. Remove MI warning printf.
5254 symtab.h: Comments. Add psymtab to symtab pointer.
5255 (PSYMTAB_TO_SYMTAB): New macro.
5256 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5257 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5259 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5261 (print_frame_info): Avoid special-casing symbols that have not yet
5264 * source.c (open_source_file): Quick path if we have already
5265 located the source file by its full name.
5267 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5268 find_pc_psymtab. When a name is found in the misc function
5269 vector, search the symbol table for its mangled name, not the
5270 name that the user typed.
5272 * bfd.h: Fix missing comment terminators, make #endifs match.
5274 * valarith.c (value_less): Handle unsigned int comparisons.
5275 Add FIXME about pointer compares, which assume host and target
5276 pointers are the same.
5278 * command.c (do_nothing_command): lint
5279 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5280 fix comments on debug symbol format for visibility. Actually set
5281 visibility of symbols.
5282 main.c (echo_command): lint; use <readline/history.h>.
5283 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5284 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5285 pointing past end of allocated memory; saber complains.
5286 obstack.h: Declare the external functions that we use.
5287 valarith.h: use <string.h>
5288 solib.c (solib_add): lint.
5290 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5292 * main.c (initialize_main): Default info_verbose to off, now that
5293 symbol reading is fast.
5294 (quit_command): Avoid clobbering exec_bfd while quitting.
5296 * Initial BFD (binary file diddling library) merger:
5297 coffread.c: Change AOUTHDR to struct exe_hdr.
5299 core.c: initialize initialized data at compile time.
5300 (core_file_command): Move from coredep.c, convert to bfd.
5301 (xfer_core_file): Convert to bfd.
5302 exec.c (exec_file_command): use bfd routines.
5304 mips-tdep.c: Remove exec_file_command and friends.
5307 * coredep.c: (fetch_core_registers) Convert core_file_command to
5308 fetch_core_registers.
5309 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5311 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5312 (my_bfd_read): More bogosity, which I don't think we call.
5313 (program_name): Remove this atrocity asap!
5315 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5318 values.c: allocate_repeat_value was not clearing the
5319 optimized_out field.
5320 (value_static_field): minor stylistic fix (wrong macro was used).
5321 valops.c (value_struct_elt_for_address): didn't work for C++
5324 * signame.c (_initialize_signame): Initialize signal names once.
5326 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5327 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5328 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5330 * remote-eb.c: Support user-settable baud rates on the serial port.
5332 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5334 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5336 * tconfig/sun3os4: Remove warning about native assembler,
5337 since it also occurs in the xconfig file.
5339 * findvar.c (registers): Allocate some slop after `registers'
5340 to prevent stray accesses from trashing the next variable.
5342 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5343 on the sun-3, by changing the #ifdef from `sun3' (which is not
5344 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5345 vars, which happened to follow `registers' in the executable.
5347 * readline/history.c (history_search): Heed gcc-2's advice
5348 and parenthesize && inside ||).
5350 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5351 tm-29k.c: Insert FSF copyright headers.
5353 * remote-eb.c: Better comments.
5355 * Makefile.dist: Update to 3.91.6.
5356 * TODO: note PREPARE_TO_STORE problem.
5358 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5360 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5362 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5364 * infrun.c (wait_for_inferior, at end): Don't set up
5365 prev_* if the inferior no longer exists.
5367 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5368 CANNOT_EXECUTE_STACK.
5369 valops.c (call_function): Use it.
5371 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5373 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5374 infrun.c (wait_for_inferior, 2 places): Use it.
5376 * values.c (value_being_returned): Only use
5377 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5379 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5380 right thing for remote-eb.c.
5382 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5383 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5385 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5386 (FRAME_FIND_SAVED_REGS).
5388 * findvar.c ({fetch,store}_registers): Check for
5389 REMOTE_{FETCH_STORE}_REGISTER macro.
5391 * findvar.c (get_saved_register): Add argument lval and
5392 change meaning of argument addr.
5393 findvar.c: Change calls to get_saved_register to reflect
5394 new calling convention.
5395 valops.c (value_assign): Use get_saved_register instead of
5396 find_saved_register.
5398 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5400 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5401 an (uninitialized) pointer to one. Use "&" when passing it
5404 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5406 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5409 * coffread.c (symbol_file_command): Put semicolon after
5411 Put safe_to_init_tdesc_context in #if defined (TDESC).
5412 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5413 coffread.c: #include <sys/stat.h>.
5414 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5415 Add missing ')' in check for "lc%" and friends. Remove
5417 Declare read_one_sym() at top of file.
5418 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5419 MC68WRMAGIC can have the same value without causing a duplicate
5422 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5424 * Allow a Makefile to be built without building the
5425 tm and xm file links that screw up builds in subdirectories.
5426 This is done with `config.gdb none', then you can do things
5427 like `make gdb.tar.Z'.
5428 * tconfig/none: Config file for no target system
5429 * xconfig/none: Config file for no host system
5430 * config.gdb: If no TM or XM files are called out by the
5431 host or target file, don't make links for them.
5433 * cplus-dem.c: Add documentation.
5435 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5436 simple error, so the user's gdb doesn't crash due to some object
5437 file problem (e.g. somebody is rebuilding the file out from under
5440 * printcmd.c (print_address_symbolic): demangle the symbol.
5442 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5443 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5444 (alldeps.mak): sort and uniq all results from this; duplicates
5445 hose gdb.tar.Z link building. Remove RCS files from
5446 tconfig and xconfig. Add config files for sun386. Add
5447 a few odd files to OTHERS and HFILES.
5449 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5451 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5452 Roll version number to 3.91.5. Make lint work in bindir.
5454 * README: Document cross-debugging and new file structure.
5456 * blockframe.c: Lint. Include "value.h" to declare read_register.
5457 (find_pc_partial_function): remove duplicate line.
5459 * command.h: Lint. Declare error_no_arg and dont_repeat.
5461 * tm-news.h: Remove inadvertently duplicated stuff.
5463 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5464 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5466 * config.gdb: Allow `config.gdb host target' form. Clean
5467 up previous change that printed bogus messages when you just said
5470 * core.c: #include "command.h" for lint.
5473 * main.c: Remove some casts of enums. Lint.
5480 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5482 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5483 read it from memory. This will allow us to save ptrace calls
5484 eventually. Changed caller single_step too.
5486 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5487 that we aren't going to use, saving many ptrace calls, especially
5488 when watchpointing or single stepping. Use some #define's for
5490 (store_inferior_registers): Ditto.
5491 (core_file_command): Use some #define's for constants.
5493 * tm-sparc.h: Add #define's for some register numbers, so we
5494 can eliminate the use of random constants in sparc-xdep.c.
5496 * stack.c (frame_command, print_frame_info, up_command,
5497 down_command) Remove frame_changed, since it
5498 causes a bug and doesn't seem to do anything useful. In some
5499 places it was used as a flag, in others as a stack level (?).
5501 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5502 default is to use the portable (vprintf) version rather than the
5504 * xm-news.h (MISSING_VPRINTF): Add.
5506 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5508 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5510 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5511 about linking debugged programs -Bstatic in the sun?os4 config
5512 files in tconfig and xconfig subdirectories.
5514 * main.c (main): Remove unreached exit(0) now that we exit
5517 * Create TODO file for online bug list. There are too many
5518 "little" bugs to keep track of on paper.
5520 * Change Projects file to refer to bug-gdb@cygnus.com
5521 rather than kingdon@ai.
5523 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5525 * Makefile.dist (VERSION): 3.91.4 now.
5527 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5528 (condense_misc_bunches): Add sanity check that misc_count is
5529 the same as the number of symbols in the bunch.
5531 * coffread.c: rename init_misc_bunches. Pass an argument
5532 to condense_misc_bunches (a zero).
5534 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5535 every time we are called; don't rely on our caller to do it.
5536 (add_file): Remove call to init_misc_bunches.
5538 * mipsread.c: Only warn, don't error, if unknown symbol types.
5539 This keeps an old gdb from falling on its face if it sees newly
5540 extended symbol info. Rename init_misc_bunches.
5542 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5544 * Merge in changes from Per Bothner for DECstations and other
5545 MIPS stuff. The rest is Bothner speaking:
5547 The next message is a merger of Alessando Forin's mips port with
5548 mine. I've tried to use my good if biased judgment to get
5549 the best of both. It *does* need testing.
5551 Some of the changes are general, *not* mips-specific.
5554 Didn't believe in little-endian bit order.
5555 There are still inconsistencies about whether flags
5556 like BITS_BIG_ENDIAN are integer (#if ...) or
5557 boolean (#ifdef ...). I tried to paper over them.
5559 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5560 Moved some misc_function code that was common to
5561 {dbx,coff,mips}read.c to symtab.c.
5562 In the process, I think I cleaned things up a bit.
5563 At the same time, moved obsavestring and obconcat to symtab.c.
5566 Removed obsolete condense_addl_misc_bunches (use
5567 condense_misc_bunches(1) instead).
5570 Needed to include <sys/dir>, at least on DECstations.
5572 valops.c, mips-tdep.c, tm-mips.h:
5573 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5574 conventions (when STACK_ALIGN is insufficient).
5575 Needed on mips, where doubles need 8-byte alignment,
5576 but ints only need 4.
5579 Removed cruft that was not being used.
5580 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5583 Print $ before register-names (I think that makes things a little
5585 Never print two instructions, even if one delays.
5586 Removed hex-disassemble set_cmd. (This is not mips-specific,
5587 so I think the argument is whether it is generally worthwhile or not.
5588 I'm inclined to think not, given how easy it is to
5589 convert between radixes in gdb.)
5592 This is basically Alessando's code.
5593 It doesn't use obstacks; I changed it to use obstacks
5594 in a few minor places where using malloc causes a
5595 memory leak. (Probably, more places could/should be changed.)
5596 I added record_misc_function where it was missing.
5597 In symbol_file_command and add_file_command, I tried
5598 to make the code consistent with more recent versions.
5599 Minor sylistic changes in parse_procedure.
5600 Make a .gdbinfo. psuedo-symbol point back to the real
5601 procedure symbol (using the isym field).
5604 This is basically from my port, but with a lot of details
5605 and a number of routines merged in from Alessando's version.
5606 I basically used my code "raw" backtrace (use heuristics
5607 from the actual code, rather than symbol table info) - though
5608 the idea is Alessandro's. I feel my code is a little cleaner
5609 here, particularly in being a little more flexible, such as being
5610 able to handle gcc-produced code (which it now can).
5611 It also doesn't do frame caching (which is not useful
5612 more recent gdb versions).
5613 I also used my code for push_/pop_dummy, more or less.
5614 I tried to incorporate AF's code for testing sigtramp
5615 while backtracing; I probably got it wrong.
5616 Added mips_print_register, which tries to scrunch as much
5617 information as possible on a screen...
5618 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5619 under mips-pinsn.c), I don't see anything mips-specific here,
5620 and I don't see it being all that useful anyway.
5623 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5624 Use more register names (rather than hard-cases numbers).
5626 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5628 * Hack up 3.90.11 changes:
5630 * Makefile.dist (depend): parameterize $(GCC).
5631 Add solib.c and solib.o.
5632 (readline): Fix vpath for both absolute or relative SRCDIR.
5634 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5635 Also, let the part I didn't understand at least compile so
5636 I can test the rest. FIXME.
5638 * dbxread.c: Fix thinko using strcmp.
5639 (init_psymbol_list): declare static.
5640 (partial_symbol_file_open): Comment cleanups better, avoid
5641 cleaning up the string table since the caller will do that.
5642 Move the stat for mod time into symbol_file_command, temporarily.
5643 (There should be a mod time for each symbol file, eventually,
5644 to control its rereading. FIXME.)
5646 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5647 SunOS, which gives error for shared libs otherwise. (From
5648 Schaefer, probably FIXME needs work for portability.)
5650 * solib.c: Move #include "param.h" to work.
5651 Lowercase all the Uppercase Letters In the Messages.
5652 (find_solib): Clean up inferior_so_name for debug printouts.
5653 Allow no argument, to mean all shared libraries.
5655 * symmisc.c: include param.h to get CLEAR_SOLIB.
5657 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5659 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5660 to 3.90.11. ChangeLog entries below are from this.
5662 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5666 * Makefile.dist (HFILES): Add tm-sunos.h.
5668 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5672 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5674 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5676 * sparc-opcode.h Added single-operand version of rett.
5678 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5680 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5681 Put parens around gcc_p in expansion.
5683 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5685 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5687 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5689 * Changes for Sun shared libraries:
5690 blockframe.c (find_pc_partial_function): If a non-text symbol
5691 is found, set *address = pc - FUNCTION_START_OFFSET.
5692 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5693 Disable breakpoints instead of giving an error.
5694 source.c (select_source_symtab): Initialize cs_pst.
5695 symmisc.c: Call CLEAR_SOLIB if defined.
5696 symtab.h: Make text{low,high} CORE_ADDR not int.
5697 (psymtab): New field addr.
5699 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5700 (record_misc_function): Give correct type for N_DATA symbols.
5701 (condense_misc_bunches): do "misc_function_count = j" regardless
5703 Take code which is shared between symbol_file_command and
5704 add_file_command and put it into partial_symbol_file_{open,read}.
5705 Split add_file_command into add_file_command and add_file.
5706 Make psymtab_to_symtab read in the string table if the file
5708 Two new parameters to read_dbx_symtab and start_psymtab.
5709 tm-sunos.h: New file.
5711 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5713 * infcmd.c: Change cont_command to continue_command and "cont"
5716 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5718 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5720 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5722 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5723 size 1,2,4,8 rather than size < 8.
5725 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5726 as necessary, not just once.
5728 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5730 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5732 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5734 * tm-news.h: Add CALL_DUMMY_*.
5736 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5738 * config.gdb: In list_host, list_target, use ${i}, not $i.
5740 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5742 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5744 * sparc-opcode.h: Change all store floating-point state register
5745 instructions to have the right match & lose fields.
5747 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5749 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5751 config.gdb: If srcdir != ., create readline directory and
5752 copy a makefile into it.
5754 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5755 consistency with POSIX.
5757 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5758 when we exit its exp_valid_block.
5760 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5762 * Makefile.dist: Bump version to 3.91.3.
5764 * Clean up handling of breakpoint commands (somewhat).
5765 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5767 inferior.h: Add breakpoint_proceeded to inferior status struct
5768 and globals; save it and restore it.
5769 (clear_breakpoint_commands): Cleanup, remove old #define.
5771 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5772 (save_inferior_status, restore_inferior_status): handle it also.
5773 (proceed): Remove earlier code that set breakpoint_proceeded.
5774 It is now set only in clear_proceed_status.
5775 (clear_proceed_status): Cleanup, use bpstat_clear rather
5776 than clear_breakpoint_commands. No callers need the stop_bpstat
5777 between clear_proceed_status and proceed.
5779 infcmd.c: Add breakpoint_proceeded definition and comment.
5780 (cont_command, jump_command, signal_command): Move call to
5781 clear_proceed_status right next to call to proceed.
5783 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5784 caller's argument while running down the chain of breakpoints.
5785 Use new variable "breakpoint_proceeded" to determine when
5786 a command that it executes moves the inferior past the
5788 (bpstat_clear): Handle NULL argument.
5789 (bpstat_clear_actions): Avoid useless call to
5790 breakpoint_auto_delete.
5791 (delete_breakpoint): Clean up bpstat's that are pointing to
5792 the deleted breakpoint from the stop_bpstat chain.
5793 (breakpoint_auto_delete): Simplify.
5795 * Clean up handling of EOF, error on stdin, etc. This was
5796 prompted by a network problem that caused gdb to go into an
5797 infinite loop filling up its malloc'd memory.
5799 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5800 not clear_breakpoints_commands, which is now gone.
5801 (main): If command_loop returns (e.g. from EOF on stdin), do
5802 a quit_command (looping back to command_loop if quit_command
5803 doesn't really quit).
5804 (command_loop): check result from command_line_input and
5805 exit if it returns NULL, rather than passing the NULL to
5807 (gdb_readline): Free malloc'd result space before returning
5810 * utils.c (query): Handle C-d to mean "yes", just as if the
5811 input was not a terminal. Also avoid infinite loop if EOF
5812 occurs in mid-input-line before newline. This allows
5813 query to be used at EOF on stdin with reasonable results.
5815 * infrun.c (proceed): Set breakpoint_proceeded.
5817 * values.c (value_as_long): Avoid infinite recursion for enums.
5818 (_initialize_values): Fix typo in help msg (kingdon).
5820 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5821 RL_LIB for linking. This allows -lreadline for linking
5822 and nothing for dependencies, once readline is a real library.
5824 * config.gdb: Jim Kingdon: give useful error message if the
5825 host or target type is not recognized.
5827 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5828 it just defines it. Dumb, but deal with it.
5830 * Jim Kingdon suggests:
5831 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5833 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5835 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5837 * Clean up Bothner's changes.
5839 * blockframe.c (clear_pc_function_cache): New function.
5840 * blockframe.c: remake cache_pc_function_* static.
5841 * dbxread.c (symbol_file_command): remove references to
5842 cache_pc_function_* variables.
5843 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5844 * printcmd.c: Avoid kludging a global variable (addressprint)
5845 to avoid printing the address of a string twice. Instead,
5846 pass the format letter 's' down low enough that it can be seen
5847 to avoid this problem.
5848 (print_formatted): Pass format arg to value_print.
5849 (restore_addressprint): Remove function.
5850 (do_examine): Avoid hacking addressprint, cleanups and such.
5851 (print_frame_args): Add a comment to a Bothner change.
5852 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5853 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5854 to wipe out the values cached in blockframe.c.
5855 * symtab.c (find_method): Add comment saying how big you must
5856 allocate to be "big enough". Per being terse again.
5857 * valprint.c (val_print): Handle format letter "s" to print
5858 strings without addresses. Add comment to vtbl printing code
5859 which casts with wild abandon. Rearrange reference-printing
5861 @0xaddr: value (print w/addressprint)
5862 value (print w/~addressprint)
5863 @0xaddr (parameter lists w/addressprint)
5864 or nothing (parameter lists w/o addressprint)
5866 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5868 * Merge more changes from Per Bothner:
5870 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5871 annoying) that I tried to improve it. Here are my suggestions.
5873 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5876 Do automatic de-reference when taking the address of a reference.
5878 Don't deref_ref when printing parameter lists.
5880 More attempts at treating refernences properly.
5882 In val_print, if deref_ref==0, don't print dangling " = ".
5884 Add COERCE_REF macro, which de-references an REF.
5886 * Merge changes from Per Bothner:
5888 * Fixed (Sony news)-specific configuration problems.
5889 * Fixed other problems with using vanilla pcc and libc (enum problems;
5890 assumption that vsprintf exists).
5891 * Some major speed-ups (finc_pc_partial_function now caches a match;
5892 parsing avoids duplicate symbol_lookup calls).
5893 * Changed handling of baseclasses (no longer use baseclasses field
5894 of struct type, use the first n_baseclasses fields instead).
5895 * Various minor changes/fixes, most C++-related.
5898 Cache the most previous match from find_pc_partial_function.
5899 (Save both low and high ends of matching function's pc range.)
5900 This speeds up the loop of infrun.c:wait_for_inferior quite
5901 a bit, and makes step/next commands much zippier.
5903 Added an enum->int cast (otherwise, some compilers barf).
5905 No longer set baseclass offset to 0, since multiple
5906 inheritance now mostly works.
5907 Added a number of casts, to shut up compiler warnings
5908 (after stabs where made enums, not ints).
5909 When discarding a symbol table (in symbol_file_command),
5910 must clear the cache introduced in blockframe.c.
5911 Don't convert $vtbl_ptr_type to vtbl any more.
5912 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5913 Mask off sign bit emitted by g++ for virtual table offset.
5914 Set voffset to -1 (not 1) for static member functions.
5916 Changed parsing/lexing of names to avoid doing symbol lookup twice
5917 (once when lexing to determine symbol class, once for real).
5918 Now only call symbol_lookup once. Fields of 'this' win especially big.
5920 Subpress printing addr twice in the case of 'x/s addr'.
5922 lookup_basetype_type is no longer used.
5923 Add find_methods as recursive helper function to decode_line_1.
5924 This allows multiple inheritance to work.
5925 Also, once one or more matches has been found, do not look in
5926 base-classes. (Baseclass methods would be overridden, anyway.)
5928 Removed baseclasses array in struct type.
5929 Instead of using baseclasses[i], use fields[i-1].
5930 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5931 Changed sign convention of voffset (previous was inconsistent).
5933 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5935 Used to assume existence of vsprintf. Re-written to not need it
5936 if HAVE_VPRINTF is undefined.
5938 typecmp was too pessimistic. Made it less so.
5940 Don't print space after address.
5941 If vtable points to a misc symbol (with 0 offset), print it,
5942 since that indicates the actual class of the object.
5943 Changed ype_print_derivation_info to use new inheritance
5944 scheme (without baseclasses vector).
5946 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5947 Also, changes needed because TYPE_BASECLASSES were removed.
5949 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5951 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5954 If there is no path set, and the symbols don't indicate what directory
5955 a file was compiled in, look in the current directory. But either
5956 a path or a known compilation directory will prevent this.
5959 Three independent bug fixes:
5960 * Remove the #if 0 block that breaks some stuff.
5961 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5962 adapt gdb to either SunOS 4.0.* or 4.1.
5963 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5966 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5969 (type_print) Demangle the name being printed.
5970 (type_print_base) Handle botched demangling without coredump (tiemann).
5973 (check_stub_method): Document routine.
5974 (tiemann) fix bug for no-arg functions
5975 Avoid clobbering beyond end of malloc'd storage.
5976 Terminate the argument list properly.
5978 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5980 * Changes merged by John Gilmore:
5983 In breakpoint_1, use new print_address_symbolic instead
5984 of find_pc_partial_function. (This forces use of assembler-level
5985 addresses, and avoids misleading non-mangled source-level names.)
5987 Generalize ansi argument such that -1 means skip arglist totally.
5988 Removed global variable print_ansi_qualifiers (which made
5989 code non-reentrant), in favor of extra explicit arguments
5990 to internal routines.
5992 Add new helper function print_address_symbolic.
5993 Use find_pc_misc_function instead of find_pc_partial_function
5994 (since we want assembler-level symbols here).
5996 Print unknown function as just "f (...)", not "f (...) (...)".
5997 Use new fputs_demangled explicitly.
5999 Fixed a typing violation (problem: value.h cannot be imported
6000 without renaming many variable in this file).
6001 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
6002 decode_line_1: Moved forward some never-reached code.
6003 Made decode_line_2 skip function prologues correctly.
6005 fputs_filtered should not demangle by default.
6006 Add new fputs_demangled to demangle on demand..
6008 Change value_struct_elt to use value_primitive_field (using recursive
6009 utility function search_struct_field). This allows foo.bar to work
6010 for multiple inheritance (so far only for data fields).
6011 Change check_field in the same way (recursive helper function
6012 to support multiple inheritance).
6013 (Note: there are more of these problems that I haven't fixed.
6014 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
6015 value_of_this: 'this' symbol name is now just "this", note "$this".
6017 Don't print static members.
6018 Avoid printing "members of <type>" if there are none.
6019 Simplified type_print_derivation_info by merging duplicate code.
6020 Remove useless blank lines in type_print_base (ptype command).
6022 Added declaration of new routine value_primitive_field.
6024 Added value_primitive_field which is generalized version of
6025 value_field that can handle multiple inheritance (non-zero offsets etc).
6026 Re-implemented value_field to call value_primitive_field.
6028 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
6030 * infcmd.c -- insert else to avoid 'delete env' coredump when you
6031 delete the whole environment. Karl Berry reported the bug.
6032 * source.c - fix openp to avoid //'s in filenames, which
6033 trigger an Emacs bug causing it to not be able to find files
6034 when running gdb in a window.
6035 * dbxread.c - zap the #if 0 that botches the add-file code.
6036 It seems to work a lot better without all the code commented out.
6038 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
6040 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
6043 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
6045 * Makefile - added a ${CFLAGS} to a couple of entries,
6046 added remote-sa.sparc.c
6047 * added remote.sa-sparc.c, a modification of remote.c
6048 which conducts a dialog directly with the SparcStation prom.
6049 * breakpoint.c, infrun.c, sparcdep.c added
6050 remote_insert_breakpoint(), and remote_remove_breakpoint()
6051 to breakpoint.c instead of directly writing breakpoint instructions.
6052 * sparcdep.c on remote_debugging,there is no need
6053 to remove signle step breakpoint instructions.
6054 * main.c added "-epoch" flag and "int epoch_interface" to main.c
6056 * printcmd.c - epoch interface sends lisp expressions to open up
6057 epoch windows on inspection.
6058 * valprint.c - added arrayprint, and addressprint and made adding
6059 format controls easier
6060 * wait.h added a couple of undef's because we were getting
6061 complaints about WSTOPSIG and WTERMSIG begin redefined.

6131 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
6132 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME

6157 step_resume_break_address != NULL, even if another_trap.
6158 If trap_expected and we enter sigtramp, then set up a
