1 Thu Oct 31 18:12:43 1991 Stu Grossman (grossman at cygnus.com)
3 * infrun.c (wait_for_inferior): another stepi/nexti fix. Ensure
4 that stop_step is 1 at bottom of main loop. I don't know why this
5 needs to be done, but it helps me sleep better at night.
7 Sun Oct 27 18:18:39 1991 Stu Grossman (grossman at cygnus.com)
9 * main.c (initialize_history): Read history after reading all
12 Sun Oct 27 14:09:25 1991 John Gilmore (gnu at cygnus.com)
14 * buildsym.c: Break out initial malloc sizes.
15 (record_line): Record directly in a subfile. Alloc on demand.
16 (compare_line_numbers): Add from xcoffread.c.
17 (end_symtab): New params say whether to sort pendings and
18 linetable. Patch block stabs if defined. Shrink linetable before
19 allocating the symtab.
20 * buildsym.h: Delete line_vector* and prev_line_number. Add
21 global_stabs and file_stabs for xcoffread.
22 * dbxread.c (start_subfile): Move to buildsym. Change above calls.
23 * symtab.h: LINETABLE(symtab) can now be null. Zap LINELIST.
24 * symmisc.c, symtab.c: Cope with null LINETABLEs.
26 * blockframe.c: Pass fromleaf to INIT_EXTRA_FRAME_INFO.
27 * tm-29k.h, tm-88k.h, tm-i960.h, tm-irix3.h, tm-mips.h, tm-pyr.h,
28 tm-sparc.h: Accept fromleaf parameter.
29 * c-exp.y (yyerror): Pass error message if given.
30 * configure.in: Add rs6000 host and target.
31 * inflow.c (new_tty): O_NOCTTY kludge for RS/6000.
32 * symfile.h (entry_point): Add.
34 Sat Oct 26 00:16:32 1991 John Gilmore (gnu at cygus.com)
36 * buildsym.c: New file. Breaks out symbol-table-building routines
37 from dbxread.c, so they can be shared with xcoffread.c.
38 * buildsym.h: New file. Declarations for buildsym.c users.
39 * dbxread.c: Remove large chunks into buildsym.c.
40 * Makefile.in: Add buildsym.c and buildsym.h.
42 * symfile.c (syms_from_bfd): New routine.
43 (add_symbol_file): Call it to do the real work.
44 (syms_from_bfd): Initialize entry_point before calling symfile_init.
45 * symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
46 Avoid declaring or setting entry_point (symfile.h & symfile.c cope).
48 Fri Oct 25 18:59:32 1991 Per Bothner (bothner at cygnus.com)
50 Various fixes to improve g++ debugging.
51 * symtab.h: Add is_const and is_volatile flags for each method.
52 These are bit fields - take their space from voffset,
53 which shrinks to 30 bits. Since voffset is now a bitfield,
54 make it unsigned for portability. This changes its interpretation
55 slightly: Static methods now have voffset 1 instead of -1,
56 and virtual offsets start at 2, not 1.
57 * symtab.c: Renamed gdb_mangle_typename to gdb_mangle_name,
58 since it now returns an entire magled method name, not just
59 the type part. This avoids some duplication.
60 It also allows us to correctly mangle const and volatile
61 methods (using the new is_const and is_volatile bit fields
63 * valprint.c (type_print_base), values.c (check_stub_method):
64 Simplify by using new gdb_mangle_name.
65 * values.c (value_headof): Fix to correctly handle single
66 inheritance (actually two fixes, either of which suffices).
67 * dbxread.c (read_struct_type): Handle const and volatile
69 * dbxread.c (read_struct_type): Yet one more place where
70 we must handle '\\' continuations.
71 * valprint.c (vtbl_ptr_name): Add final '\0'.
73 Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com)
75 * tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of
76 short return values for sparc and 68k. Patch from Paul Eggert.
78 * coffread.c, coredep.c, i386-xdep.c: install patches for
79 SysV/386 3.2 from Mauro DePalma.
81 Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
83 * core.c (core_file_info), exec.c (exec_file_info): Print file
84 type. Use printf_filtered.
86 * valops.c (value_fetch_lazy): Avoid 0-length fetches.
88 Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
90 * dwarfread.c: Add casts to remove compiler warnings.
92 * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
93 tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
94 tm-sun3.h: Remove locally duplicated code for calling functions
95 in the inferior. The only differences were in the specific trap
96 vectors used and whether or not an fpu was present. These are
97 now handled by appropriate definitions of BPT_VECTOR and
98 HAVE_68881 respectively. Other minor obvious cleanups.
100 * valops.c: Correct a minor misspelling.
102 * utils.c: Remove local BSD/USG hacks that are now in libiberty.
104 * dwarfread.c: Remove prototype for dwarfwarn. Does not work
107 Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
109 * stack.c (frame_command): Always print. Use new
110 frame_select_command to select a frame without printing.
112 * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
114 Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
116 * dwarfread.c: New file for DWARF debugging format support.
118 * elfread.c: New file for ELF object file format support.
120 * procfs.c: New file for SVR4 /proc (process file system) support.
122 * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
125 * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
127 * xm-m68k.h: New file for host machines with m68k cpu.
129 * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
130 Add elfread.o and dwarfread.o to OBS.
132 * symfile.h: Add "elf" to list of supported formats in comment.
134 * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
135 types to gdb, builtin_type_long_double, builtin_type_complex, and
136 builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
137 TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
138 TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
139 TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
140 types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
142 * infrun.c: When using SVR4 /proc interface instead of ptrace(),
143 call proc_set_exec_trap() to setup child to stop at first instruction.
145 * inftarg.c: When using SVR4 /proc interface, call proc_wait()
148 * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
149 supply_fpregset(), and fill_fpregset(), which are machine
150 dependent support routines for SVR4 /proc interface.
152 * utils.c: Add warning_setup() and warning(). Warning() behaves
153 the same as error() except that it returns normally rather than
154 jumping back to command level. Modules that don't want to call
155 warning() for some reason, but want to produce their own warnings,
156 can call warning_setup() to ensure compatibility with the way
157 warning() and error() deal with the terminal.
159 * symtab.c: Make internal errors produce more useful messages.
161 * tm-68k.h: Move code that is duplicated in almost every single
162 m68k based machine's configuration files to this common file.
163 Duplications in the configuration files still need to be removed
166 * infrun.c (child_create_inferior): System V versions must call
167 setpgrp() with no arguments, to comply with prototyping typically
170 * munch: Add support for SVR4 style nm output.
172 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
173 file specific fields from the partial symbol table structure and
174 replace them with a pointer to private data for each different
175 flavor of object file reader to initialize appropriately.
177 Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
179 * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
182 * mipsread.c (fixup_undef_type): New function. If a struct /
183 union / enum is defined in a header file but nowhere else used,
184 (by typedefing, pointer referencing or declaration) the mipsread code
185 builds the complete tree for the structure but leaves its code as
186 TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
187 Guess its type based on the details of the members.
189 Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
191 * infrun.c (wait_for_inferior): Check return value from
194 Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
196 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
197 by my last edit to this routine.
199 Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
201 * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
202 FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
203 the values before putting them into the dummy code. (From Peter
206 Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
208 * configure.in: added ebmon target.
210 Wed Oct 16 22:49:58 1991 John Gilmore (gnu at cygnus.com)
214 * Makefile.in: Roll VERSION to 4.2.
215 * README, TODO, WHATS.NEW: Update.
217 * core.c (core_open): Improve error message for bad file.
218 Pass .reg virtual memory address to fetch_core_registers to help
219 it find the registers in the core-file header.
220 * coredep.c (fetch_core_registers): Take new argument, use it,
221 and pass it to register_addr to locate the block of registers.
222 * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
224 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
225 Sequent N_FN_SEQ like everybody else's N_FN.
227 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
228 * tm-i386v.h: #endif guck.
229 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
230 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
231 * xconfig/tahoe: Add REGEX, which seems to be missing.
233 * coredep.c: Add <sys/types.h> for SCOnix.
234 * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file.
235 * printcmd.c (print_formatted): Flush output before disassembly.
237 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
239 * doc/refcard.tex (sec "Working Files"): consistent metavars and
240 other improvements, due to comments by François Pinard
241 (pinard@iro.umontreal.ca)
243 * doc/gdb.texinfo (appendix "Installing GDB"): changes in
244 configure, and improvenets related to Pinard's refcard comments
246 Tue Oct 15 08:45:12 1991 John Gilmore (gnu at cygnus.com)
248 Changes from Fred Fish:
249 * tm-68k.h (FPI_REGNUM): Add.
250 * infrun.c (child_create_inferior): flush stdout and stderr
252 * configure.in: Handle amigados, amix hosts and targets.
253 * inflow.c: Handle TIOCGLTC_BROKEN for Amiga.
256 * values.c (show_convenience): Use printf_filtered.
257 * main.c (define_command): Check result of lookup_command for

263 * i387-tdep.c (double_to_i387): Fix typo for double_to_ieee_extended.
264 * utils.c (_initialize_utils): If !ISATTY, don't paginate.
265 * configure.in, tconfig/decstation, xconfig/decstation: Rename
266 dec3100 to decstation.
268 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)
270 * doc/gdb.texinfo: Catch up to changes recorded here in ChangeLog
271 (nodes Continuing and Stepping; Memory; Targets) clarifications
274 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
276 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move
277 REGISTER_U_ADDR to corresponding xm- file. Sugg. by Peter Schauer.
279 * symmisc.c (print_partial_symtabs): Add printpsyms debug cmd.

282 generic routines for calling inferior functions.
284 * blockframe.c (inside_main_scope, inside_entry_scope): New.
286 * copying.awk: Filter formfeeds out of copying & warrantee.
287 Make them available as `show copying' and `show warrantee' also.
288 * main.c (print_gnu_advertisement): Advt `show' commands.
290 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)

293 core-file reading code.
294 * core.c (get_core_registers): Avoid coredump if no .reg section.
296 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
298 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
299 This avoids coredumps under `set print object on' in value_headof
300 (called erroneously by value_from_vtable_info) for `p &struct'
301 or `p *struct'. From Peter Schauer.
303 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
305 * Makefile.in: Roll version to 4.1.2.
306 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
307 size from BFD (but, FIXME, we don't yet read external nlists's and
308 convert them to internal nlists's before handling them -- we still
309 assume they have the same size and alignment.) Use SET_NAMESTRING
311 * exec.c (exec_file_command): Move dead coff-encapsulation code
313 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.
315 Fri Oct 4 22:30:06 1991 John Gilmore (gnu at cygnus.com)
317 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
318 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
320 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
322 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
323 * mips-xdep.c (store_inferior_registers): Don't try to
324 write the (pseudo) FP.
325 * mipsread.c (parse_partial_symbols): Improved algorithm for
326 setting pst->texthigh.
328 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
330 * doc/Makefile: make TEXINPUTS include . everywhere
332 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
334 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
335 vestiges of typevectors, which were for symsegs and are no longer
336 used. (From a question by Eliot Dresselhaus
337 <dresselh@RFT30.nas.nasa.gov>).
339 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
341 * dbxread.c, coffread.c: static-ize functions that were
342 gratuitiously external. (From Fred Fish.)
344 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
346 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
347 until it is large enough.
349 * dbxread.c (read_type): Handle error case slightly better.
350 Make complaint message not C++-specific.
352 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
354 * infrun.c (wait_for_inferior): Fix step/next so that you only
355 stop at the beginning of a new line. This fixes various problems
356 with for loops, nested if-else's and switch statements.
358 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
360 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
361 between symtabs and psymtabs become ordinary error()s.
363 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
364 properly, making "end pc" correct in shared lib psymtabs.
365 (From Guy Harris <guy@auspex.com>.)
367 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
369 * dbxread.c: Enable, but soften, const_vol_complaint.
370 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
371 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
372 should be file-scope, not global.
373 (read_struct_type): Remove ancient multiple-inheritance warning.
374 (read_range_type): Check base type, complain & patch if undefined.
375 * stack.c (frame_info): Demangle the function name in `info stack'.
378 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
380 * eval.c (evaluate_subexp_for_address): Don't use
381 TYPE_POINTER_TYPE directly (it might be zero if this type has
382 never had a pointer created before); use lookup_pointer_type.
383 * symtab.c (lookup_method_type): Arguments were swapped in all
384 callers, so fix it here. I'm amazed this worked at all!
386 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
388 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
389 "bss" rather than "data" symbols, but which still conflict.
392 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
393 * core.c (core_files_info): Shorten output.
394 * exec.c (exec_files_info): Ditto.
395 (build_section_table): Ignore zero-length sections.
396 * language.c, printcmd.c: Lint.
397 * language.h (get_frame_language): Declare.
398 * saber.suppress: update.
399 * stack.c (find_relative_frame): Remove complex code that was
400 #if 0'd, stick with simple code. Lint.

409 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
410 (Reported by Mark Peek <mark@imagen.com>.)
412 * solib.c (solib_map_sections): Relocate all sections, even
413 though only the text section's size is tracked. Mark ld_text
414 for eventual elimination as we generalize to N sections.
416 * infrun.c (wait_for_inferior): Don't check if the PC is in a
417 call_dummy if we were stopped by a random signal that is being
418 passed to the program. This produced wierd results when calling
419 functions in the inferior and signals (e.g. SIGALRM) were in use.
421 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
423 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
424 Bugfix from Paul Eggert <eggert@twinsun.com>.
425 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
426 * valprint.c (print_floating): Print 9 digits for IEEE floats.
429 Mon Sep 23 15:50:07 1991 John Gilmore (gnu at cygnus.com)

435 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
439 * Makefile.in (VERSION): Set to 4.1.
440 * language.c (set_language_command): Print useful help message,
441 and restore the language string after giving help.
442 * valprint.c (typedef_print): Print typedef in C or M2.
443 * symtab.c (list_symbols): Use it.
444 * main.c (main): Avoid any output before (gdb) prompt when -q.
445 * language.c (set_language_command): Handle errors by restoring
446 the language string to its current state (fix from A. Beers).
447 * doc/gdbint.texinfo: Roll in information from README. Rearrange
448 "how to install" and "how to print the doc" stuff so it drops
450 * configure.in: Rename rtpc CPU to romp to match config.sub.
451 * README, WHATS.NEW, TODO: Update for gdb-4.1.
453 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
455 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
456 autoloading shared libs, copyright etc on GDB startup, clean up $_
457 and $__ index refs, set/show listsize and related updates to list
458 cmd. New host/target configs.
460 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
462 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
463 from main Makefile.in version definition
464 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
466 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
468 * doc/gdb.texinfo: merge new language-switching and lang-specific
471 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
473 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
474 compilers (which may lack stddef.h).
476 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
478 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
479 N_WARNING are the same except for the N_EXT bit, so just use their
480 values alone, rather than OR-ing them with N_EXT.
482 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
484 * mipsread.c (parse_lines): Deal with negative extended line
487 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
488 global symbol conflicts.
490 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
492 * .gdbinit: Move 'set complaints' to top, so it runs even in
493 case we aren't debugging GDB.
494 * language.c (_initialize_language): Fix type check and range
495 check documentation strings.
496 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
497 language.c can use it. (Though language.c should really not be
498 handling warnings/errors the way it does, FIXME.)
499 * symtab.c (lookup_primitive_type): const lint.
501 Bugfix from Peter Schauer:
502 * source.c (lines_to_list): Make signed, to avoid comparison
503 going unsigned and complaining that -3 is too high for 21 lines.
504 * stack.c (lines_to_list): Ditto.
506 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
508 * Makefile.in (HFILES): Add minimon.h.
509 (VERSION): Roll version number to 4.0.95.
510 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
511 New rules for building distributions. Normal distribution
512 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
513 one level up from here; it calls make-proto-gdb.dir to build a
514 directory `proto-gdb' which is an image of the release. The old
515 `gdb.tar.Z' rule still works too.
516 * config.sub, configure: Roll in latest from ..
518 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
520 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
521 new-target, and new-config chapters; fix minor typos; come closer
522 to usual GNU markup conventions for @file @samp @code @var.
524 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
526 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
527 * mipsread.c (parse_partial_symbols): Enter the name of all
528 structs/unions... into the psymtab so we can access them if the
529 symtab is not read in.
530 * mips-tdep.c: Remove some unneeded #includes.
531 * xconfig/dec3100: Add HAVE_STRSTR.
533 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)

642 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
644 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
645 entries are enclosed herein. Not all of these changes
646 have been merged into the master GDB sources -- check the
647 ChangeLog above here for the merge log.
649 Mon Jun 3 17:05:45 EDT 1991
651 m2-exp.y Created. Tested outside of GDB for a few days. Proper
652 operators were added, C specific operators and tokens
653 removed. yylex() revamped to some extent. Still things
654 missing from the grammar, such as sets.
655 Tested for two weeks in GDB v3.5.
657 Tue Jun 11 17:23:48 EDT 1991
659 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
660 so they are built-in. Sort of a hack.
662 Fri Jun 14 12:53:51 EDT 1991
664 m2-exp.y Added range checking for numeric constants. Any numeric
665 constant is assumed to be of builtin type INTEGER unless:
666 (1) it is octal or hexadecimal, in which case it is a
667 CARDINAL; (2) it is too big to fit into an INTEGER, in
668 which case it is a CARDINAL.
669 eval.c Added simple range checking for +, -, and * on integers.
670 Doesn't work very well for *, since 6 * 1,000,000,000 =
671 1,705,032,704, which fails the simple test of result >=
672 first_operand, no matter in what order the operands are.
674 Tue Jun 18 14:11:30 EDT 1991
676 Broke the parser into parts, one containing the C grammar and the other
677 containing code to be shared by all of the grammars.
679 The following files no longer exist:
684 The following files were added:
686 c-exp.y (The C grammar)
687 m2-exp.y (The Modula-2 grammar)
688 parser-code.c (Code that is shared by the above grammar)
692 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
693 now necessary to use the Bison compiler compiler, since it
694 will generate function/variable prefixes other than yy.
696 Tue Jun 18 16:47:49 EDT 1991
698 symtab.[ch] Added the external variable working_lang, than holds the
699 value of the current working language.
700 Added the ennumerated type language_mode, with the values
701 language_auto and language_manual, the former meaning that
702 GDB sets working_lang as needed, and the latter meaning
703 that the value of working_lang is totally under user
705 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
706 REAL, BOOLEAN and CHAR. Also added the type codes
707 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
708 utils.c Added set_language_command and show_language_command to
709 implement the GDB support commands "set language" and
711 expression.h A number of identifiers were added to the type exp_opcode
712 to facilitate Modula-2 builtin functions, integer
713 division, and array indexing.
715 Wed Jun 19 13:25:58 EDT 1991
717 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
718 if the language specified by working_lang requires the use
719 of strict typing of expressions. Eventually, even this
720 will be able to be changed by the user.
721 Added the macro RANGE_CHECK, which evaluates to non-zero
722 if the language specified by working_lang requires the
723 checking of a value against the domain of its type.
724 Eventually, even this will be able to be changed by the
726 language.[ch] Predicates involving types (simple_type, ordered_type,
727 same_type, integral_type, numeric_type, character_type,
728 boolean_type, float_type) are added. These predicates are
729 based on the current value of working_lang, and are handy
732 Wed Jun 19 15:39:34 EDT 1991
734 eval.c Added the function type_array_rank which computes the rank
736 valarith.c Added the funtion value_bool, which when given a integer
737 value.h value (ie. struct value *) as an argument, it returns a
738 boolean value (ie. struct value *) true if that integer
739 is non-zero, and a boolean value false otherwise.
740 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
741 will print out properly.
743 Wed Jun 19 16:36:34 EDT 1991
745 valops.c Added the function value_capitalize, which returns it
746 value.h argument capitalized if its argument is a lowercase
747 letter, or the argument unchanged if its argument is not a
749 valarith.c Added the function range_check_p, which returns non-zero
750 value.h if its value argument is between the integral bounds upper
752 Added the function range_check_enum_p, which makes sure
753 that its value argument is a valid member of the domain of
755 Added the function range_check_range_p, which makes sure
756 its value argument lies between the upper and lower bounds
757 of its type argument, which must be a ranged type.
758 Added the function check_array_index, which range and type
759 checks an index of an array.
760 Added the function value_multi_subscript, which computes
761 array[idx1,idx2...idxN], given a value array and an array
762 of values representing indicies.
763 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
764 unpack_long to work with TYPE_CODE_BOOL and
767 Wed Jun 19 18:04:08 EDT 1991
769 symtab.c Stored pervasive types in a structure and make
770 lookup_pervasive_type() a lookup function that was based
771 on working_lang. If lookup_pervasive_type() returned
772 non-zero, then that value was returned (a fix, since
773 before it simply wouldn't return the pervasive type.)
774 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
775 non-zero if the language specified by working_lang means
776 "conversion" when it says "cast".
777 valops.c Added the function value_real_cast(), which performs a
778 value.h *cast*, not a *conversion*, which is what value_cast()
779 does when it can. In particular,
780 value_cast(<float_type>,4) = 4.0, while
781 value_real_cast(<float_type>,4) = some mess.
782 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
783 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
784 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
785 and MIN on integral types. *NOTE*: These are currently
786 hardcoded to work only if there are 8 bits per storage
788 eval.c Made logical functions call value_bool to return a
789 properly typed boolean value, based on working_lang.
791 Thu Jun 20 11:55:27 EDT 1991
793 valprint.c Types now print out in a Modula-2 fashion. This works for
794 the cases when the type is printed out step-by-step, that
795 is, it doesn't work when the name of a structured type
796 (which includes the keyword "struct", etc.) is simply
798 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
799 since type specifications in C and Modula-2 are very
800 different. The C printing of a type is very recursive,
801 whereas in Modula-2 it is generally very simple. C has
802 type prefixes and suffixes, which have no real analogue in
803 Modula-2. Maybe type_print() should call a language
804 specific type printer. This is also advantageous if we
805 compile GDB to exclude some of the languages. We'll just
806 leave those functions out.
808 Thu Jun 20 16:57:10 EDT 1991
810 dbxread.c When reading the complete symbol table in (via
811 psymtab_to_symtab()), the number and types of function
812 arguments are added to a function type. define_symbol()
813 calls add_param_to_type() to accomplish this.
814 Assumption: when we come across a function definition
815 (N_FUN symbol with an 'f' or 'F' in the name), its
816 arguments will appear before another function definition.
817 When a function is found, a pointer to its type is placed
818 in the global in_function_type. Changes that
819 add_param_to_type() makes are to this global.
820 valprint.c The type of a function now includes (for Modula-2) the
821 types of its parameters.
822 eval.c Type checking and a check for the proper number of
823 arguments is now done for function calls. Not sure of the
824 impact this has on C++ member function yet.
826 Thu Jun 20 19:58:48 EDT 1991
828 valprint.c Rewrote the type printer. Broke it into two language
829 specific parts, adding the functions type_print_m2() and
831 An unfortunate consequence is this: if you debugging a C
832 program in Modula-2 mode (why?), info types does not work
833 well with regular expressions, since the types are printed
834 out in Modula-2 terminology, but stored in C terminology.
835 language.[ch] Added the functions new_type_last(), type_keyword(), and
836 type_sep() to aid in the printing of typedefs.
837 symtab.c Made the printing of typedefs as language independent as
838 possible through calls to new_type_last(), type_keyword(),
841 Fri Jun 21 11:50:26 EDT 1991
843 dbxread.c Check all incoming ennumerated types. If it looks like
844 Modula-2's BOOLEAN type, then change the type_code of the
845 type to TYPE_CODE_BOOL so we can process it as a boolean
847 valprint.c Replaced some of the 0x%x with calls to sprintf and
848 hexformat() in val_print().
849 language.[ch] Added the function hex_to_string(), which converts its
850 integral argument to a hexadecimal number (format is
851 language based) and returns the result as a string.
853 Mon Jun 24 12:25:07 EDT 1991
855 valprint.c Some functions call type_print_1() directly, instead of
856 value.h using type_print(), so they can specify where (column) to
857 print things. Since type_print() takes care of language
858 dependence, that needs to be called first. Added a
859 parameter depth to type_print() (so it is now like
860 type_print_1). Changed type_print to type_print_at, and
861 made type_print a macro that passes a depth argument of
863 symmisc.c Changed all calls to type_print_1 to calls to
865 Makefile.dist Made it possible to build GDB for a specific set of
866 depend languages. Do this by passing a definition for the macro
867 LANGS to make. LANGS should be a string containing a
868 space-separated list of language names (ie. LANGS="c m2").
869 The default is to build all languages. Note that grammar
870 files must follow the naming convention of <lang>-exp.y.
871 gdb.lang This holds the current value of the LANGS macro. It is
872 examined every time make is called, and is updated if
874 eval.c Added #ifdef _LANG_<lang> to these files.
875 expread.c Still need to add them to dbxread.c and coffread.c.
883 Mon Jun 24 16:33:11 EDT 1991
885 language.[ch] Added the functions hexformat_pre() and
886 hex_to_string_pre(), which take a prefix argument to
887 include in the format string. Thus, hexformat_pre("08") will
888 return "0x08x" (if the working language is language_c).
889 Made hexformat() and hex_to_string() calls to the above
890 with "" as the prefix argument.
892 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
893 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
894 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
895 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
896 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
897 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
898 valprint.c, vax-pinsn.c
900 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
901 calls to hexformat() and hex_to_string(). Format strings without
902 the leading "0x" were ignored.
904 depend Updated to take the above into account.
907 Tue Jun 25 15:27:18 EDT 1991
909 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
910 and type_check_t to keep track of the current state of
911 range and type checking.
912 main.c Added the variables range_mode, range_check, type_mode,
913 and type_check to record the current state of range and
914 type checking. Added initialization code to main().
915 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
919 Tue Jun 25 17:57:08 EDT 1991
921 dbxread.c process_one_symbol() updates the variable (enum language)
922 source_lang based on the extension of the filename
923 contained in the N_SO sybmol that started this symtab.
924 When end_symtab() is called, the value of source_lang is
925 put into the language field.
926 stack.c select_frame() sets working_lang (and possibly type_check
927 and range_check) to the language field of the symtab
928 associated with the frame that is selected if working_mode
929 is language_auto. If working_mode is language_manual, a
930 warning is printed and working_lang is not set.
931 language.c Added the function set_type_range(), which sets the value of
932 type_check and range_check (if their modes call for
933 automatic setting) based on the current value of
934 working_lang. A non-zero argument will cause the current
935 settings to be output.
938 Wed Jun 26 14:51:40 EDT 1991
940 eval.c Added range checks on assignment.
941 m2-exp.y Added the grammar for sets to the language. Currently,
942 these do not do anything except print an error message.
944 Wed Jun 26 17:01:04 EDT 1991
946 m2-exp.y Added the ability for parse_number() to parse negative
947 numbers. A global flag is set upon encountering a unary
948 minus. This was done to make, for example, 1 parse as a
949 CARDINAL, and not as an integer, per Wirth's examples in
950 Programming in Modula-2 ed.4.
951 valprint.c Added support for "set radix 2" by then setting
952 output_format to 't'.
953 eval.c Implemented range checking on subrange types. Added calls
954 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
955 Implemented MIN and MAX for ennumerated types. The
956 minimum value of an ennumerated type is defined by Wirth
957 as the first identifier, and the maximum as the last.
958 m2-exp.y Made octal numbers ending with "B" be characters and those
959 ending with "C" be numbers, per Wirth's book. (p. 34)
961 Thu Jun 27 14:11:52 EDT 1991
963 stack.c select_frame() now only sets working_lang, it does not
964 notify the user. If working_mode is language_manual, then
965 a warning is issued once.
966 main.c At the end of each call to execute_command(), working_lang
967 is checked against the local static (enum language)
968 current. If they differ and working_mode is
969 language_auto, the new settings of language, type and
970 range checking are printed out.
971 stack.c Modified frame_info() to include the language of the
972 current frame in the output of "info frame".
973 language.[ch] Added the function language_str() which returns the name
974 of the current language.
976 Fri Jun 28 15:33:14 EDT 1991
978 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
979 the language. INCL and DECL currently cause an error,
980 since sets are not implemented yet. INC and DEC are
981 implemented as PREINCREMENT/PREDECREMENT with one
982 argument, and as ASSIGN_MODIFY with two arguments.
983 eval.c Added type checking to the above cases.
984 value.h Added not_lval_constant to the lval_type ennumerated type.
985 not_lval_constant means that the value is a constant
986 value; that is 3 or 'a' or TRUE, not as in a constant
987 identifier. This is used to help coerce numbers such as 3
988 to either signed or unsigned numbers.
989 valops.c Added the function value_coerce_constants() which coerces
990 constant integers as following: if one is a constant and
991 the other is not, the constant's type is set to the type
992 of the other argument. If both are constants and one is
993 signed, the other is converted to a signed constant.
995 Sat Jun 29 17:26:29 EDT 1991
997 valarith.c Added a better range checker. It now checks range
998 (successfully) on integral operations [+-] (signed and
999 unsigned) for any C sized type. Still does not work well
1000 for multiplication.)
1001 int_in_size() returns an integer that is coerced to fit into
1002 specified number of bytes.
1004 Mon Jul 1 13:04:14 EDT 1991
1006 language.[ch] Added the function binop_result_type(), which returns the
1007 builtin (struct type *) type that would be the result of a
1008 binop on the two values V1 and V2.
1010 Wed Jul 3 19:22:53 EDT 1991
1012 source.c Extended source_info() to include the source language in
1013 the output from "info source".
1015 Fri Jul 5 13:48:52 EDT 1991
1017 utils.c Moved the support functions for the GDB set/show commands
1018 dealing with language into language.c.
1019 language.c Added the function language_info(), which displays info
1020 about the current working language, type and range check
1021 settings. Called via the GDB command "info language".
1022 Added an initialization routine _initialize_language(),
1023 that sets defaults for the language, type and range
1024 variables and sets up the new GDB commands.
1025 main.c Language setup moved to language.c.
1028 Mon Jul 8 10:10:22 EDT 1991
1030 valarith.c Debugged the range checker for arithmetic. Still does not
1031 work for multiplication very well.
1033 Mon Jul 8 12:40:37 EDT 1991
1035 language.[ch] Added the function value_true() which returns non-zero if
1036 its argument represents a boolean true value.
1037 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1038 check the truth of an expression.
1040 Thu Jul 11 12:51:34 EDT 1991
1042 language.[ch] Added the predicate structured_type(), which returns
1043 non-zero if the argument is a structured type.
1044 Added the predicate pointer_type(), which returns non-zero
1045 if the argument is a pointer type.
1046 eval.c Added the ability to do addition and substraction on
1047 pointers and integers. This case simply bypasses the
1050 Thu Jul 11 14:41:42 EDT 1991
1053 Added the symbol N_DEFD (0x4a) which is a definition
1054 module dependency that is used by the GNU Modula-2
1055 compiler and the linker. It is not important to GDB,
1056 except that [dbx|coff|mips]read.c should ignore these
1059 Fri Jul 12 16:07:00 EDT 1991
1061 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1062 0 in val_print(). Also added statements to the else part
1063 to coerce type (argument to val_print) to a pointer type
1064 if it is an "array of unspecified length".
1065 valops.c Added the function value_m2_string(), which returns a
1066 (value) value which is a constant string, whose type is
1067 (ARRAY [0..n] OF CHAR). The length field of the type
1068 structure is set to zero, so it will be interpreted as an
1069 "array of unspecified length".
1070 stack.c Moved the language/frame mismatch check to
1071 main.c:execute_command().
1072 main.c The working language is recorded each time
1073 execute_command() is executed. If working lang has
1074 changed during its execution, then the new
1075 language/type/range info is printed out for the user. If
1076 the working language does not match the language of the
1077 frame, a warning is issued.
1079 Sat Jul 13 16:16:39 EDT 1991
1081 eval.c Moved all the type-checking stuff for operators to
1082 language.[ch] language.c. This is so we can keep language-specific
1083 stuff (like for what type operators are defined) in
1085 language.[ch] Added the function binop_type_check(), which checks to see
1086 if its two (value) arguments are type-compatible with its
1087 opcode argument. The opcode should represent an operation
1088 involving an operator. Also added the macro function
1089 unop_type_check, which calls binop_type_check with a
1090 NULL second argument.
1091 expprint.c Added Modula-2 operators to the op_print_tab, so info
1092 expression.h break works correctly. Also added "op_string", which
1093 returns the string corresponding to the (enum exp_opcode)
1094 opcode that is its argument.
1097 Sat Jul 13 18:26:18 EDT 1991
1099 coffread.c Added code to record the type of function arguments with
1100 each paricular function. Code is very similar to that
1102 dbxread.c Moved add_param_to_type() to symtab.c
1103 symtab.[ch] Added function add_param_to_type() from dbxread.c
1105 *** NOTE: The above additions have not been tested.
1107 Mon Jul 15 12:50:47 EDT 1991
1109 langauge.[ch] Added the functions type_error and range_error, which work
1110 like error() except if the type/range mode is set to
1111 *_mode_warn, then they do not do a return_to_top_level(),
1112 but merely print a warning.
1113 Also changed [set|show]_[type|range]_command() to support
1114 the new "warn" feature.
1116 Thu Jul 18 17:50:54 EDT 1991
1118 mipsread.c Added code to record the type of function arguments with
1119 each particular function. Code is very similar to that
1122 *** NOTE: The above additions have not been tested.
1124 Fri Jul 19 11:19:10 EDT 1991
1126 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1127 UMIN_OF_SIZE, which when given a size of a numeric type,
1128 return the maximum and minimum value it can hold. UMAX...
1129 and UMIN... return the result for unsigned types.
1130 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1131 struct types. They call above macros.
1132 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1133 avoid a name conlict with the above.
1134 c-exp.y Added range checking on numeric constants in
1135 parse_number() for completeness.
1136 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1137 return 0 if working_lang is not language_c.
1139 Thu Aug 8 14:17:22 EDT 1991
1143 breakpoint.c Documentation strings of some commands changed to
1144 eliminate the references to the C language where
1147 Tue Aug 13 15:48:03 EDT 1991
1149 m2-exp.y Added qualified identifiers to the grammar. The semantics
1150 are slightly different from those of the GDB operator ::
1152 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1153 type_exp, where type_exp is any valid type expression.
1155 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1156 printcmd.c Modified ptype_command() so it actually parses the input
1157 (necessary for type expressions with scope qualifiers).
1158 Added the function ptype_eval() which expects an
1159 expression composed of one OP_TYPE element.
1160 *.[ch] Replaced all occurences of parse_c_expression with
1162 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1164 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1166 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1168 Small fixes from Peter Schauer:
1170 * infrun.c (child_attach): Lint.
1171 * solib.c (find_solib): Handle shared libs version 2.
1173 Small fixes from David Wood:
1175 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1179 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1180 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1182 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1183 chars_per_line is at maximum (user typed `set width 0'). Fix
1184 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1186 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1188 * coredep.c: include ptrace.h where necessary.
1189 * mipsread.c(parse_lines): fix unsigned char problem that was
1190 messing up line numbers on SGI's and possibly other MIPS based
1192 * infrun.c (child_create_inferior): use better test to check
1193 return val from setpgrp().
1194 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1195 for sgi/irix support.
1197 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1199 * mipsread.c (parse_symbol): Put non-static procedures
1200 in the global block.
1202 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1204 Patch together `text_start' and `text_end' for 29K port.
1206 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1207 variables and set them based on the exec file.
1208 * am29k-tdep.c: declare text_start.
1209 * valops.c (call_function_by_hand): declare text_end.
1211 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1212 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1213 because machines that do this will also have to know to
1214 set NEED_TEXT_START_END. Besides, it was a redundant way to
1216 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1217 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1218 NEED_TEXT_START_END.
1220 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1222 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1224 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1225 Pass MUNCH_DEFINE to munch whenever we run it.
1226 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1227 format string; use 0x%x instead.
1228 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1229 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1230 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1231 * inflow.c: Handle `short' process group IDs.
1232 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1233 and check for ptrace errors.
1234 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1235 (coff_symfile_init): Initialize text_bfd_scnum.
1236 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1237 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1238 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1239 Merge target arm case with other "easy" cases. Add target
1240 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1241 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1243 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1244 * munch: Cope with RT/PC putting fns in data segment.
1245 Restore ability to override `nm' by specifying MUNCH_NM.
1246 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1247 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1248 and remote-adapt. Remove encapsulated coff #define's (the
1249 support should go in BFD, and gdb shouldn't know or care).
1250 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1251 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1252 * tm-29k.h: Update BADMAG (though it should go away).
1253 Allow the register definitions to be overridden in another
1254 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1255 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1256 DUMMY_SAVE_GR96, for handling kernel calling conventions
1257 that use GR64+ rather than GR96+.
1258 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1259 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1260 overrides various things.
1262 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1263 child_attach does, making a clean stop in the newly attached
1265 * remote-eb.c: Lint.
1267 * coffread.c: Make coffread independent of any particular
1268 variant of COFF. Avoid #include-ing any particular one except
1269 internalcoff.h. BFD now passes key values for symbol reading
1270 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1271 and the symbol masks and shifts); use them.
1272 Remove obsolete end_of_text_addr.
1274 * exec.c: Remove unused include files.
1276 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1278 * Makefile.in (documentation targets): Pass $(M4).
1279 Bugfix from eggert@twinsun.com (Paul Eggert).
1281 * stack.c (down_silently_command): Check for stack existence.
1283 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1285 * Makefile.in (VERSION): Update to 4.0.3.
1287 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1289 * core.c (core_file_command): Print frame at coredump with
1290 its level number, by calling print_stack_frame.
1291 * frame.h: Add selected_frame_level, print_stack_frame.
1292 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1293 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1294 Change print_sel_frame and print_selected_frame callers to
1297 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1298 * symfile.c (free_named_symtabs): Ditto.
1299 * main.c (main): wrap_here needs an arg.
1300 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1301 (solib_add): Avoid noise.
1302 (solib_create_inferior_hook): Lint.
1303 (sharedlibrary_command): Move dont_repeat to here.
1304 * utils.c (error): Call wrap_here to force buffered output.
1306 Small patches from Peter Schauer:
1308 * coffread.c (start_symtab): Free any existing line_vector before
1310 (read_coff_symtab): Ditto for type_vector.
1312 * source.c (lines_to_list): New variable, replacing function.
1313 (all uses): Use as variable.
1314 (_initialize_source): Add 'set listsize' and 'show listsize'.
1315 * utils.c (lines_to_list): Remove function.
1316 * stack.c (print_frame_info): Use as variable.
1317 * defs.h (lines_to_list): Remove declaration.
1319 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1321 * breakpoint.c (insert_breakpoints): Restore warning about
1322 the program might be running in another process, but only for
1323 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1324 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1326 * utils.c (error): if error_pre_print is set, print the string
1328 * main.c (main, print_gnu_advertisement, print_gdb_version):
1329 Reformat legalese so it always prints, but acts as an "I'm here"
1330 message while symbols are being read. If any errors occur,
1331 print a few newlines to set off the message and start it at the
1332 left margin. Remove mention of "help" command, and don't yak
1333 about symbol reading.
1334 (catch_errors): Error string is now printed first in case of
1336 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1337 suggest the "help" command.
1339 * Makefile.in (VERSION): Set to 4.0.2.
1341 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1343 * .gdbinit: Remove useless "rr" command. Set complaints
1344 to 1 for people debugging gdb.
1346 * breakpoint.c, remote-vx.c: Reword strings printed by
1347 catch_errors callers.
1349 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1351 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1352 (Fix from kenc@viewlogic.com.)
1354 Fix some infrastructure to be able to cope with host and target
1355 machines with different sized basic types (ints, ptrs, etc).
1356 (Idea from pierre@la.tce.com (Pierre Willard).)
1358 * values.c (value_from_longest): Rename from value_from_long.
1359 Handle pointer types as well as integers, so that targets with
1360 different pointer sizes from the host can be accomodated.
1361 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1362 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1363 uses of value_from_long to value_from_longest.
1364 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1365 the correct pointer type to value_from_long{est}.
1367 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1369 * remote-vx.c: Remove obsolete code for calling functions via
1370 vxworks kludge interface (it referenced value_from_long).
1372 * valops.c (value_string): Find malloc with lookup_misc_func, not
1375 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1377 Make writing to files work properly. (Fixes to BFD are also needed.)
1379 * core.c (core_open): Open file ourselves, read or r/w, depending on
1380 write_files. Use bfd_fdopenr.
1381 * gdbcore.h (write_files): New variable.
1382 * exec.c (write_files): Define variable, add set&show for it.
1383 (exec_file_command): Use write_files to open for read or r/write.
1385 Make shared library reading happen automatically. These changes
1386 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1388 * inferior.h (stop_soon_quietly): Add to exported variables.
1389 * infrun.c (child_create_inferior): call solib hook, if defined.
1390 (child_attach): call solib hook, if defined.
1391 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1392 (find_solib): Use lookup_misc_func rather than hand-rolled.
1393 (symbol_add_stub): New stub for catch_errors.
1394 (solib_add): Avoid output if !from_tty. Catch errors rather
1395 than just calling symbol_file_add and bombing.
1396 (solib_create_inferior_hook): Interface with the target process
1397 to let it read and alloc shared libs, then figure out what it did.
1399 * core.c (validate_files): Fix typo, soften warning.
1400 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1402 * utils.c (fputs_demangled): Avoid duplicate printing if
1403 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1405 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1406 (Fix from pierre@la.tce.com (Pierre Willard).)
1408 * main.c (catch_errors): Change argument to a char * from an int,
1409 since a char * can point to a struct full of glop, but an int
1410 is not guaranteed to be able to hold a pointer.
1411 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1412 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1413 * core.c (core_open, solib_add_stub): Adapt.
1414 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1416 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1418 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1419 by adding .NOEXPORT target.
1421 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1425 * Makefile.in (VERSION): Roll to 4.0.
1426 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1428 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1430 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1433 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1436 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1438 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1439 reflect above name change
1441 * WHATS.NEW: correct pointer to refcard.
1443 * doc/gdb.texinfo: update New Features, Installing
1445 * doc/gdbint.texinfo: add short description of configure +template
1447 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1449 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1451 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1453 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1454 tar file, add dependencies for referenced doc files.
1456 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1458 * coffread.c, symfile.c, stack.c: saberized.
1460 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1462 * doc/refcard.tex: permuted Essential Commands sec
1464 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1466 set/show symbol-reloading
1467 default set complaints 0
1469 RET-repeat disabled after prompted long displays
1470 processID (attach) interpretation of 2nd GDB cmdline arg
1472 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1474 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1475 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1476 breakpoint.c, main.c: lint.
1478 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1480 Install new configuration scheme for GDB and friends.
1482 * config.sub: Translate ordinary names to three-part names.
1483 * configure: Use three-part names internally.
1484 * configure.in: Translate three-part names to filenames.
1486 * README, WHATS.NEW: Update for gdb-4.0.
1487 * Makefile.in: Roll VERSION to 3.99.
1489 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1491 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1492 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1493 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1494 to single structures rather than arrays; when passing
1495 their address, use &. This avoids trouble with bdead compilers.
1496 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1497 instead. This avoids portability headaches.
1498 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1500 * source.c (open_source_file): Avoid ANSI const bdeath by
1501 skipping declaration and then casting result value.
1502 * tm-hp300bsd.h: Clarify comment.
1503 * utils.c (strstr): Result is const char *; ANSI bdeath.
1504 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1505 since system include file defines it differently from "defs.h",
1506 though the two are equivalent for our purposes.
1507 * tconfig/hp300bsd: Add m68k-tdep.o.
1509 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1511 * tconfig/sun*4: Remove warnings about system assembler.
1513 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1515 * mcheck.c: Avoid warning about undeclared abort fn.
1516 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1517 it causes recursive calls to error() when used in cleanups.
1518 To do so requires that we make it a function, so we do.
1519 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1520 * utils.c (do_cleanups): Remove the current cleanup from the
1521 chain *before* calling it, in case error() is called from it.
1522 The result won't be pretty, but won't be an infinite loop either.
1524 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1526 * dbxread.c (read_struct_type): Grok anon structs for C++.
1527 (vb_name, vptr_name): Null terminate these strings.
1529 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1531 Minor bug fixes from BSD Net2 gdb:
1533 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1534 returns 0, there is no previous frame.
1535 * breakpoint.c (commands_command): If !from_tty, don't call
1536 input_from_terminal_p().
1537 * dbxread.c (record_misc_function): Speed up slightly.
1538 (compare_psymbols): Ditto.
1539 * infcmd.c (do_registers_info): Take a second argument to
1540 determine whether to print float registers. "info registers"
1541 does not do so anymore. "info all-registers" does, now.
1542 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1544 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1545 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1549 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1550 executing_breakpoint_commands if we are interrupted by error.
1551 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1552 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1553 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1554 catch_errors() so we can setup the frame regardless of whether
1555 the shared libs work.
1556 * ieee-float.c (double_to_ieee_extended): Get exponent from
1557 right place in little-endian systems. From John Carey.
1559 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1561 * main.c: Remove unused terminating_signals and catch_termination().
1562 (long_options): Terminate with a zero element.
1563 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1564 (gdb_readline): Make call-compatible with readline.
1565 (init_signals): Improve comments re vfork vs. signal.
1567 * utils.c (prompt_for_continue): Use new gdb_readline().
1568 If we prompt for continuation, we don't let CR repeat the previous
1569 command, once we get back to a prompt. It's too easy to keep
1570 hitting CR, expecting "--more--" prompts, and have some long
1571 command start repeating on you.
1573 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1575 * blockframe.c (frameless_look_for_prologue): Speed up by
1576 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1577 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1578 Define two variants, one faster.
1579 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1580 and return zero, rather than giving an error.
1581 (setup_arbitrary_frame): Initialize the PC in the new frame.
1582 (skip_prologue): Add a second arg saying whether we're just
1583 checking for a frameless function or not.
1585 * core.c (core_open, core_close, core_xfer_memory): Move
1586 section table pointers and bfd* into the target_ops.
1587 (core_open): Allow errors in shared lib reading, etc.
1588 (core_files_info): Describe shared library sections.
1590 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1591 exec_files_info, set_section_command): Move section table
1592 pointers and bfd* into the target_ops.
1593 (add_to_section_table): Add BFD to section table.
1595 * target.c (target_xfer_memory, target_info): Pass target to
1596 xfer_memory and target_info functions.
1599 * gdbcore.h: Move struct section_table.
1600 * target.h: New home of struct section_table.
1602 * solib.c (solib_add): New argument is the target_ops whose
1603 section list is to be added to, if any. Reallocate the
1604 sections in that target to add any that come from shared libs.
1605 (throughout) so_sections renamed to sections.
1606 (solib_xfer_memory): Deleted.
1607 * tm-sunos.h (SOLIB_ADD): Add target argument.
1608 (SOLIB_XFER_MEMORY): Delete.
1610 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1611 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1612 from target_ops. It's the same on all targets. Add two section
1613 pointers to target_ops.
1615 * stack.c (find_relative_frame): Dump ancient algorithm for
1616 "down", just use handy "next" pointers.
1617 (frame_command): Don't error if there is no stack; let user
1620 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1621 modifies static state in the parent process; new_tty itself
1622 runs in the child and modifies the child's file descriptors
1623 to match the saved static state.
1624 * infrun.c (child_create_inferior): Call new_tty_prefork,
1627 * infptrace.c (child_xfer_memory): Add ignored target arg.
1628 * remote-eb.c (eb_xfer_inferior_memory): ''
1629 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1630 * remote-vx.c (vx_xfer_memory): ''
1631 * remote.c (remote_xfer_memory): ''. Rename from
1632 remote_xfer_inferior_memory.
1634 * main.c (main): Only try to attach "corefile" argument if
1635 it starts with a digit.
1637 * symfile.c (symbol_reloading): New "set/show" variable.
1638 (symbol_file_add): Shorten message about symbol reading.
1639 (add_symbol_file_command): Merge with add_syms_addr_command,
1640 since this should work on all targets now.
1641 (stop_whining): Default to zero, to shut up complaints
1642 about bad symbol tables on many systems.
1643 (free_named_symtabs): Just exit unless symbol_reloading.
1645 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1646 and add comment explaining shared library screw.
1648 * source.c: #if defined => #ifdef.
1650 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1652 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1654 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1656 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1657 (doc/Makefile knows how to make one for local config)
1659 * Makefile.in: use doc/Makefile for doc targets
1661 * doc/Makefile: GDB documentation now has its own Makefile
1662 doc/refcard.tex: renamed from "gdbrc.tex"
1663 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1664 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1667 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1669 * values.c (baseclass_addr): When reading target memory, use the
1670 length of the basetype, not the upper type. We've only malloc'd
1671 enough space for the basetype, leading to errors in free().
1673 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1674 ends up as a function specially, since we know the actual type of
1675 the pointed-to address. This (somewhat) fixes display of
1676 expressions that include misc_function_vector names. Try `cond 1
1677 !strcmp("a","b")' then `i b'.
1679 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1680 The child can be proceeded from inside wait_for_inferior in
1681 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1682 getting skipped in that case.
1684 * expprint.c (print_subexp): Use filtered output, since the
1685 subroutines we call use it, otherwise the output is horribly
1686 mangled, since output of wrappable stuff comes out late.
1688 * Makefile.in: Bump VERSION to 3.98.1
1690 * infrun.c (child_create_process): Use execlp to find the
1691 shell to exec our target program. This requires some fiddling
1692 with `environ' since there is no execlpe().
1694 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1696 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1697 Minor rearrangement of refcard permits two new make targets--
1698 gdbrc.dvi DVI output for refcard, using CM fonts
1699 gdbrc.ps PostScript refcard, using PS fonts
1701 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1705 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1706 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1708 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1710 * doc/gdb.texinfo: last changes for release.
1711 Minor typo and formatting fixes; incorporated most fixes remaining from
1712 filed mail commenting on earlier drafts.
1714 Added warnings: pipes don't work in run command;
1715 conditions are converse of assertions;
1716 step over fn without debug info goes to next fn;
1717 vars may have "wrong" values near fn entrance, exit
1719 Added example from Kingston on printing repeated nonadjacent values
1721 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1722 shell mode for signals
1724 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1725 doesn't sound so much like its parent "Stopping and Continuing"; also
1726 moved entries on continue to top of section, so they don't get lost.
1728 Improved installation directions in appendix, added manual formatting
1731 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1733 * configure.in: Remove xm.h and tm.h even if we aren't linking
1734 new ones, so "./configure sun4; ./configure none" does the right
1735 thing. Assume that alldeps.mak and depend are already built in
1736 srcdir, and avoid running "make" (particularly "make depend",
1737 which involves "gcc") from inside configure. Build Makefile
1738 directly rather than building Makefile.conf first.
1739 * configure: Regenerate with above changes.
1740 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1741 to 3.98. Revise gdb.tar.Z procedure to produce a file
1742 called gdb-$(VERSION).tar.Z but which unpacks into a
1743 directory called "gdb". Move non-source files out of
1744 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1745 (depend): Don't try to do "gcc expread.y".
1746 (expread.o): Update dependencies by hand.
1748 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1751 Fixed a variety of small typos that prevented info from formatting
1752 cleanly; altered too-long heading for GPL Appendix, as discussed
1753 w/RMS; Changed date on cover to July 91.
1755 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1758 (1) Applied some fixes due to comments from Larry Breed (easier ones
1759 through chapsec 5.2)
1760 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1761 it's broken in latest texinfo
1762 (3) Introduced *some* use of [] for optional arguments, where
1763 explanation is not simpler by listing cmd w arg and cmd w/out arg
1764 separately. Still not using @deffn.
1765 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1766 couple of headings are too long. Need patches to texinfo or revision
1769 * Partial update to README (which still needs work for this
1770 release!): (1) use of configure corrected for new script,
1771 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1773 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1775 * symtab.c (lookup_symbol): Don't complain right off about
1776 no debug symbols; use the misc function vector first.
1777 (list_symbols): Use misc function vector to find symbols
1778 that don't have debug info, and print them.
1779 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1780 PC range doesn't match symtab PC range, as it does on the
1781 MIPS because our symtab reading isn't perfect.
1783 * dbxread.c (dbx_symfile_read): Make warning about
1784 "no debug symbols" slightly nicer.
1786 * source.c (select_source_symtab): If "main" symbol exists,
1787 but decode_line_spec can't find line info, don't just return
1788 a zero; try other source symtabs or give an error.
1790 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1791 their low addresses first, then rip through fixing high addrs.
1793 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1794 <runene@ifi.uio.no>.
1795 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1797 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1799 * Minor, mostly mechanical, cleanup of doc subdir for clean
1800 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1801 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1803 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
1805 Mostly MIPS and general symbol-reading fixups.
1807 * doc/gdbint.texinfo: Add documentation on symbol-reading
1810 * mipsread.c: Remove kludges around #include "ecoff.h".
1811 Remove redefinitions of a_magic, etc, no longer used.
1812 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
1813 Fix global overview comments to match symfile.c protocol.
1814 (mipscoff_new_init): Eliminate cur_hdr if we have one.
1815 (mipscoff_symfile_read): Eliminate unused code. Avoid
1816 sorting all the symtabs, when all we have read here is psymtabs.
1817 The symtabs are sorted as they are created anyway. Tell
1818 condense_misc_bunches whether we're mainline.
1819 (psymtab_to_symtab_1): Pass filename when recursing, to make
1820 stack trace more informative.
1821 (parse_partial_symbols): Assume cur_hdr as argument.
1822 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
1823 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
1824 the TYPE_NAME of char *, since that's done in symfile.c.
1825 (free_numargs, parse_symbol, add_symbol, add_block,
1826 shrink_linetable): Declare these fns void.
1827 (upgrade_type): Convert tree of if's to switch. Clean up
1828 bogus "off == 0" handling with a complaint. Avoid setting
1829 field bitpos and bitsize of array with lower and upper bounds.
1830 Check specified bitsize of elements against their actual type's
1831 bitsize, and complain if different. Complain about unknown
1833 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
1834 (psymtab_to_symtab_1): Print names of subsidiary files that
1835 are being read in. FIXME, we read far too many files. This code
1836 is not the problem, the problem is in parse_fdr where the psymtabs
1838 (cross_ref): Result should indicate that we used one aux entry
1839 normally, or two if we encountered a "next" entry. This used
1840 to leave the caller pointing at the wrong aux entry.
1841 (add_symbol): If overflowed cur_block, reallocate it larger,
1842 chase all pointers to it, and complain(), rather than clobber memory.
1843 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
1844 (new_field): Only allocate one field initially, not two.
1845 Pull ++ out of macro argument. Simplify.
1846 (_initialize_mipsread): Avoid initialization of importd
1847 global_psymbols and static_psymbols.
1849 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
1850 to properly set pst->symtab; avoid searching for it.
1851 (symfile_fns): Improve comments, add a FIXME.
1852 * dbxread.c: Update comments to reflect symfile protocol.
1853 (read_ofile_symtab, end_symtab): Return the symtab.
1854 (psymtab_to_symtab_1): Set pst->symtab.
1856 * coffread.c (coff_symfile_read): tell condense_misc_bunches
1857 whether we're mainline.
1859 * symfile.h (sym_fns): Remove unused sym_discard member.
1860 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
1862 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
1863 the environment variable is not.
1864 * infcmd.c (finish_command): Use filtered printfs.
1865 * cplus-dem.c: Add struct tags to a few unnamed structs.
1866 * valops.c (value_coerce_array): Improve comments.
1867 * valprint.c (type_print_varspec_suffix): Print array size only
1868 if greater than zero.
1869 * m88k-tdep.c: Shift some lines left by one space, that had
1870 apparently been trashed at some point.
1871 * TODO: More things to do, a few got done.
1873 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1875 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
1876 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
1878 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
1879 * expread.y, findvar.c, symmisc.c: Ditto.
1880 * printcmd.c (address_info): Update printed forms of LOC_
1881 symbols. Elim LOC_EXTERNAL.
1882 (print_frame_args): Keep track of param stack offsets before
1883 re-looking up to find the local register param is kept in.
1885 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
1886 Further integration of mipsread into gdb. Eliminate unused
1887 routines, duplicate declarations. Handle static symbols in
1888 psymtabs as well as external symbols. When reading symtabs,
1889 insert symbols into the correct block (global, static, or a local
1891 (read_mips_symtab, parse_partial_symbols): Don't pass useless
1893 (mipscoff_symfile_read): Don't call select_source_symtab.
1894 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
1895 rather than SYMBOL_VALUE.
1896 (parse_external): Comment clobbering of top_stack.
1897 (parse_partial_symbols): Update comments. Allocate and parse
1898 static symbols as well as external symbols. FIXME, enum values
1899 are not handled in this pass, but should be. Inline new_psymbol.
1900 Use SYMBOL_VALUE_ADDRESS.
1901 (psymtab_to_symtab_1): Read symbols into global static block
1902 by default (until enter some function's local block context).
1903 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
1904 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
1906 * source.c (select_source_symtab): Select a source symtab
1907 from either the symtabs or, failing that, the psymtabs.
1908 (list_command): Update error message.
1909 (forward_search_command, reverse_search_command): Use getc, not
1910 fgetc, for speed. FIXME, add comment about buffers that die if
1911 overrun by long line.
1913 * values.c (unpack_field_as_long, modify_field): Avoid shifting
1914 by an entire word, which is not portable, if we have a 32-bit
1915 field. (Code in dbxread.c already turns such bitfields, if
1916 aligned, into ordinary ints, but fixing this will help for other
1917 symbol formats and for future changes.)
1918 * core.c (core_open): Handle ANSI const brain death.
1919 * utils.c (vprintf): Fix varargs typo.
1921 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1923 * findvar.c (find_var_value): Handle &function better.
1924 * TODO: Document work needed on &fn and &array.
1925 * printcmd.c (print_address_symbolic): New arg is the prefix
1926 to print if a name is printed.
1927 (print_address_demangle): Honor "set print address" now.
1928 Use new arg above to improve spacing of output.
1929 * valprint.c (val_print): When printing function pointers,
1930 print symbolic form too.
1931 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
1933 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1935 * core.c (memory_error): Reword error msg to mislead less.
1937 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
1939 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
1940 parse_partial_symbols): Use newer BFD internals (external_filehdr
1941 and external_aouthdr), byte-swap the fields that we care about
1942 before using them, and make the file header data local to
1943 read_the_mips_symtab rather than global.
1945 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
1947 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
1948 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
1950 * main.c (command_line_input): Flush stdout and stderr
1951 before every call to readline. This reportedly fixes a bug
1952 that comes up in Sys V running emacs-gdb and/or xxgdb,
1953 when stdin/out are pipes or sockets.
1955 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1957 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
1958 Avoid declaring Makefile dependencies, because GNU Make stupidly
1959 tries to update it if we do.
1961 * coffread.c: Revise for minor changes to bfd internal coff
1964 * configure: If -template= is given a relative path, make it
1965 absolute before recurring in subdirectories.
1967 * configure, configure.in, Makefile.in: Install "configure" script
1968 as replacement for config.gdb.
1969 * config.gdb, Makefile.dist, Makefile.sdir: Remove
1970 * README: Update for configure, mostly. FIXME.
1972 * Add dec3100 as equivalent to littlemips. Indicate in all host &
1973 target config files that they are for the host. When the lines
1974 get copied into the Makefile, this makes it more obvious what's
1977 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1979 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
1980 tabs, which end up in the disassembler output inadvertently.
1982 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1984 Make it compile cleanly in an ANSI GCC2 environment.
1986 * blockframe.c: <stdio.h>
1987 * cplus-dem.c: free takes a void *, ifdef __STDC__
1988 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
1990 * defs.h (alloca): Avoid doing anything if alloca already def'd.
1991 * stddef.h, stdlib.h: Remove these files.
1992 * symtab.c: Avoid declaring qsort, close.
1993 * symfile.c: Avoid declaring close.
1994 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
1995 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
1997 Assorted other changes.
1998 * dbxread.c: include "libaout.h", not "liba.out.h".
1999 * printcmd.c (print_frame_args): Set recurse properly for
2000 indentation of struct and array parameters.
2001 * valops.c (value_cast): Allow cast to void.
2002 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2003 single_step() in a target-independent fashion.
2004 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2005 set up to be ready to continue. This makes us target independent.
2006 * infptrace.c (child_resume): Remove call to single_step; now
2007 can single step a SPARC target of any kind.
2009 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2011 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2012 docn into separate sections---basically chapters, plus two loose
2013 pieces that can be configured to go in different places. This
2014 allows GNU m4 to preprocess the manual without coredumping.
2016 * Makefile.dist: tell TeX where to find texinfo.
2018 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2020 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2021 the new target "rdl-apps.texinfo" which captures the Makefile
2022 variable that records where to find the Readline libraries.
2024 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2026 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".

2029 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2031 * README: Update for release 3.95.
2032 * config.gdb: Don't create readline dir in subdir builds.
2033 * main.c: Include with "..." form for non-system include files,
2034 so "gcc -MM" for "make depend" works.
2035 Include readline files with "...h" rather than <readline/...h>.
2036 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2038 * coffread.c: Undo minor damage done by Rich Pixley. Use
2039 different internal and external representations of COFF
2040 data structures. Use new BFD routines for swapping them in and
2042 * symfile.c (free_named_symtabs): Avoid freeing file names that
2043 are null or empty. Old i960 tools seem to produce files that
2044 claim to have empty names, causing each successive file read
2045 to blow away the previous one.
2046 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2047 Move deferred_stores to top of file, but don't separate its
2048 #define's from its variable. Add commentary.
2049 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2050 favor of keeping the (working) config.gdb. Move readline
2053 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2055 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2057 * infptrace.c (fetch_registers): no result, since now void.
2058 * tconfig/news: target depends on m68k-tdep too.

2062 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2065 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2066 applied various small fixes due to or inspired by RMS comments
2068 * doc/gdb.texinfo: finished using all RMS comments, save those for
2069 appendices on readline and cmd history (which are in other source
2072 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2074 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2075 chapter 9; (2) documented 'break' command's menu mode for
2076 overloaded names, in response to hgs problem report C++ p-31
2078 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2080 * doc/gdb.texinfo: (1) better introductory example; (2) more
2081 consistent use of @code, @samp, @file, @kbd throughout; small
2082 cleanups to first three nodes; (3) new "Contributors" node;
2083 (4) Appendix, Renamed Commands; (5) divert specialized startup
2084 instructions to "Targets" chapter for generic manuals, while
2085 leaving them up front for manuals specific to specialized
2086 environments; (6) apply fixes from RMS comments through chapter 4.
2088 * pretex.m4: modify explanatory text slightly (and redefine
2089 "regexp") to keep GNU m4 from complaining. (It still crashes
2090 later, but one step at a time...)
2092 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2094 * readline/readline.c (update_line): Avoid dereferencing a pointer
2095 before comparing it to its bounds. Saber caught this.
2096 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2097 and only set PC if tgetstr returned non-null. Saber caught this.
2099 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2101 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2102 stuff for config manual) here where it counts; updated
2103 to use new subdir structure (gdb/doc/).
2105 * Makefile: generated from above via
2109 * gdbint.texinfo: added instructions on generating gdb.info* files
2110 locally for release. These are ordinary info
2111 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2112 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2113 to generate these, so we distribute them already formatted.
2115 * gdb.texinfo: included full Info node and menu crud (as generated
2116 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2118 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2119 put in comments-for-future gdb.info target (one day makeinfo will
2122 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2124 * gdb.texinfo: Updated to include new or old undocumented
2125 commands, at least the following (perhaps some others I forgot to
2126 record): info f, info float, info path, info program, info s, info
2127 set, info source, info terminal, info types, info user, set/show
2129 Also covered all recent GDB command renames for v4.
2131 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2133 * mipsread.c: Rather than keeping count of how many symtabs
2134 and psymtabs we have, for sorting purposes, count them when
2135 we need to sort. This fixes bug in rereading of symbol tables.
2137 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2139 * infcmd.c: renamed "info path" to "show paths"

2154 symtab.h, target.c, target.h: Lint.
2155 * core.c: setup and select frame after reading shared libs,
2156 else reading shared libs will clobber them. Lint.
2157 * utils.c (error): Force out any buffered wrap text.
2159 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2161 * remote.c: Remove decls of memory_insert_breakpoint
2162 and memory_remove_breakpoint, no longer used. (Suggestion of
2165 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2166 to make it easier to interface to "configure"'d libraries.
2168 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2170 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
2171 aliases for set/show print.

2717 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2719 Permit symbols to be superseded when new symbol files have
2720 been read in, particularly for VxWorks.
2722 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
2723 to the main file, as well as to include files. Also, put global
2724 functions into the global psymtab, to make "i fun" work.
2725 (end_psymtab): Free named symtabs and psymtabs for a file, once a
2726 new psymtab for it has been read.
2727 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
2728 a file, once a new symtab has been read for it.
2729 * mipsread.c: FIXME. We need to do the same for MIPS, but it
2730 looks harder to determine the top-level block before it's been
2731 queued to the psymtab list.
2733 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
2734 If we have wiped out any old symbol tables, clean up at end of
2736 (symbol_file_command): Don't reference symfile_fns if it's zero.
2738 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
2739 defines for the blocks of a blockvector that contain global and
2740 file-static symbols and the first of the smaller scope contours.
2741 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
2742 decode_line_1, make_symbol_completion_list): Use the above.
2743 * coffread.c (end_symtab, patch_opaque_types): Ditto.
2744 * dbxread.c (end_symtab): Ditto.
2745 * expread.y (block): Ditto.

2749 * symtab.c (list_symbols): Process the first symbol of the
2750 static psymbols list.
2751 (types_info): Restore this function from its untimely #if 0.
2752 It's not perfect, but it is better than nothing.
2753 (_initialize_symtab): Restore "info types".
2755 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2757 * m68k-stub.c: Remote stub for 680x0's, created from
2758 rem-m68k.shar (which is removed).
2759 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
2760 Remove RCS log stuff now that we use CVS and it blows our diffs.
2762 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2764 * symmisc.c (free_named_symtab): Make it work, in its current
2765 kludgy fashion. Change result to indicate if we blew away bkpts.
2766 * dbxread.c (end_symtab): Accumulate result from
2767 free_named_symtab and print warning if we blew user's state.
2768 * symfile.h: free_named_symtab now returns an int.
2770 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
2772 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
2773 is the first symbol read, even if not mainline.
2774 (dbx_psymtab_to_symtab): symfile might be zero, cope.
2775 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
2776 (set_section_command): New command ("section xxx yyy" -- should
2777 be renamed to "set section xxx yyy" FIXME) which sets the
2778 base address of a section of the exec file, overriding the
2779 virtual address that BFD reports.
2781 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2783 * exec.c: Add add_syms_addr_command to exec_ops, so you can
2784 load symbols at any address while examining an exec file.
2786 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2788 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
2789 for printing the float info is host-dependent, not
2790 target-dependent. FIXME.
2791 * i386-pinsn.c: Move #includes to top, remove useless ones.
2792 * i386-tdep.c: Don't bother including <.../reg.h> since we
2793 don't use it (and it doesn't exist on host systems).
2795 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
2796 Convert negative numbers properly.
2797 (ieee_test): Make numbers really random; fix format arg.
2799 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
2800 * core.c (core_detach): Unpush core_ops, which might not be on
2801 top. We used to just pop the top, which broke things. Don't
2802 need dont_repeat() any more.
2803 (core_file_command): Psst! Don't repeat it.
2804 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
2805 * expprint.c (print_subexp): Avoid switch fallthru on
2806 BINOP_ASSIGN_MODIFY, so we can print += and such.
2807 * frame.h: Fix typo.
2808 * inflow.c (kill_command): After killing inferior, print our
2809 current frame in the core file, if we have one.
2810 (generic_mourn_inferior): When inferior dies, either select
2811 the current frame (in the new target, e.g. core file), or
2812 set both the current and selected frames to NULL.
2814 Changes from Peter Schauer.
2816 * infptrace.c: Avoid <sys/ptrace.h> on USG.
2818 * Make all file names fit in 14 characters (sigh and damn!):
2819 mv hp300hpux-xdep.c hp300ux-xdep.c
2820 mv symmetry-xdep.c symm-xdep.c
2821 mv symmetry-tdep.c symm-tdep.c
2822 mv convex-opcode.h convx-opcode.h
2823 mv tm-vxworks960.h tm-vx960.h
2824 mv tm-vxworks68.h tm-vx68.h
2825 mv Makefile.srcdir Makefile.sdir
2826 mv gdb-int.texinfo gdbint.texinfo
2827 mv remote-sa.m68k.shar rem-m68k.shar
2828 mv remote-multi.shar rem-multi.shar
2829 * Makefile.dist, README, config.gdb, convex-pinsn.c,
2830 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
2831 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
2834 * command.c (user_info_1, user_info): New command for listing
2835 the user-defined commands.
2837 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2839 * dbxread.c (really_free_pendings): Clear file_symbols
2840 and global_symbols after freeing them; otherwise, running
2841 this function twice (if it appears twice on the cleanup
2842 chain), we try to free things twice.
2844 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
2845 based on text_addr (the address of text in core), not on addr (the
2846 offset between text in the .o file and in core). This change
2847 is from Peter Schauer.
2849 * main.c: Define ALL_CLEANUPS as a cast of zero.
2850 (return_to_top_level): Use it.
2851 (main): Do all cleanups after each command run as part
2852 of the gdb startup sequence. Also do all cleanups before
2853 entering the command loop, and every time we exit the command
2854 loop and reenter. Before, the cleanups from the startup sequence
2855 were being left undone until the first error!
2856 (command_loop): Rename do_nothing cleanup to command_loop_marker
2857 so we can see it easily when examining the cleanup chain.
2858 (init_signals): Add another do_nothing for signal handling.
2859 (quit_command): Only try to kill target if it has execution.
2860 Problems in the target stack got us into a state where
2861 inferior_pid was nonzero but none of the targets had execution.
2862 In this state you couldn't exit gdb.
2864 * dbxread.c: Two changes from Peter Schauer.
2865 (echo_command): Fflush output after an echo command.
2866 (show_history): Pass all args to cmd_show_list.
2868 * utils.c (init_malloc): Call mtrace to turn on tracing
2869 if the environment variable MALLOC_TRACE is set to a file name.
2870 * mtrace.c: Add source file which provides a log of every malloc,
2871 free, and realloc to a trace file.
2872 * mtrace.awk: Add source file which analyzes the trace file.
2873 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
2874 (VERSION): Roll to 3.94.3.
2876 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
2877 (check_duplicates): Don't bother with watchpoints.
2878 (set_raw_breakpoint): Comment about danger of this routine.
2879 (watch_command): Parse and eval all args before calling
2882 * solib.c (find_solib): Avoid error in referencing memory to
2883 see if any more shared libraries have been added. This is
2884 particularly useful if the target has terminated. Bug reported
2887 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
2888 in bringing up 3.94.2 on the Sun-3.
2890 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
2891 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
2892 expression (in scope) before reenabling watchpoint.
2893 * signame.c (init_sigs): Add missing declaration of i, fix
2894 sys_siglist declaration.
2895 * source.c (list_command): Fixed range computation to use
2897 * stack.c (backtrace_command): Do not allow command if target has
2898 no stack, print informative error message.
2899 * target.c (target_command): Do not write into command line
2900 because this fails if the target command is used in a user defined
2901 command. [This change was enhanced by gnu to support any-
2902 unique-prefix matching on target names.]
2903 * valops.c (value_struct_elt): Avoid infinite loop on an
2904 erroneous attempt to print the member of function (try p main.p).
2906 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2908 * expread.y (name_no_typename): Avoid reduce/reduce errors
2909 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
2910 Since the GDB parser really doesn't use name_no_typename in a
2911 name-only context, the parser can't tell the diff between
2912 names and numbers here. Avoid allowing a name_no_typename
2913 to be a NAME_OR_*INT to resolve the conflict.
2915 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2917 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
2919 * valprint.c (val_print_fields): bitfield printing didn't handle
2920 byte order. Indirect through a few more fns to cope.
2922 * values.c (modify_field): also cope with byte order.
2924 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2926 Cleanup for release 3.94.2:
2928 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
2929 include files. Roll version to 3.94.2.
2931 * coffread.c (init_stringtab): Read length into unsigned char
2932 array before swapping; don't assume 32-bit longs.
2934 * target.c (target_info): Don't bother with get_sym_file, just use
2935 the symfile global variable.
2936 * symtab.h, symfile.c (get_sym_file): Delete it.
2938 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
2939 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
2940 (read_type): Replace one more error() with complain().
2942 * mipsread.c (parse_partial_symbols): Replace printf with complain.
2944 * i960-tdep.c: Fix copyright attribution.
2946 * config.gdb: Quote all backquotes in doublequotes. You can
2947 quote me on that. BSD 4.4 shell found this one.
2949 * infptrace.c (throughout): The third argument to ptrace is an
2952 * infrun.c (wait_for_inferior): When program has terminated, we
2953 have to call target_terminal_ours before we pop that target off
2954 the stack (e.g. before a call to target_kill or
2955 target_mourn_inferior). This fixes problem where a program
2956 terminates, then GDB stops for (tty output) and you have to type
2957 "fg" to the shell to resume it. FIXME: This code for what to
2958 do after termination really should be in normal_stop instead.
2960 * gdbcore.h (read_memory_check): Change declaration; it changed
2963 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
2964 4.4 prereleases, this avoids a bug in their sgtty compatability
2966 * remote.c: Use terminal.h rather than hand-rolling the same.
2968 * signame.c, signame.h (psignal): Arg is unsigned, not int.
2969 * utils.c (strsave, strstr): Fix arg types.
2970 * valprint.c (val_print): lint
2972 MIPS symbol table support from Per Bothner:
2974 * symfile.c (symtab_fns): Remove initializer table that needs to
2975 be hacked for each new symbol file format supported.
2976 (add_symtab_fns): New function, chains symbol table
2977 handlers into the global list.
2978 (symfile_init): Search this list.
2979 * symfile.h: Add next pointer, declare add_symtab_fns.
2980 * coffread.c (_initialize_coffread): Call add_symtab_fns.
2981 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
2983 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
2984 symbol *). Thus, we no longer need the hack to trash
2985 pst->filename. Good, since that hack confused code in symfile.c!
2987 (reorder_symtabs, destroy_all_symtabs): Removed static
2988 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
2989 Instead, the latter now uses a temporary array (stack-allocated
2990 from an obstack, and then freed).
2992 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
2993 haven't been set in the outermost stBlock of a procedure. This was
2994 a problem with f77 binaries on Ultrix 4.?.
2996 (new_symtab, new_symbol, new_type): Continue changing code to use
2997 obstacks more and otherwise conform to dbxread internal style.
2998 Made the free_code of symtabs be free_linetable (as in dbxread)
2999 instead of free_contents. This implies memory leaks when reading
3000 a new symbol table, until the conversion is finished. Did change
3001 (struct symbol) and (struct type) to be allocated on the
3002 symbol_obstack. Blocks and blockvectors are among the things
3005 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3006 tested much, but it solved one problem (reported by Meissner), and
3007 cleans up some other things. The problem happened when an
3008 included file contains actual code (functions) and not just
3009 definitions. The mips coff is a little inconvenient there, since
3010 it may cause a procedure to be mapped to the wrong psymtab.
3012 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3013 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3014 this will need work for the new core paradigm.
3016 Opcode patches from the net:
3018 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3019 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3020 missing altogether - they are added here. From Bruce Bauman.
3021 * mips-opcode.h: The low mask for C0 instructions was too small.
3022 From Garrett Lau. I modified the fix to check the entire 32-bit
3025 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3028 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3030 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3032 * dbxread.c (read_type): Pointer subtraction (value_sub in
3033 valarith.c) sometimes failed because the types of the
3034 pointers being subtracted were not identical.
3035 These differed because dbxread.c was allocating pointer types
3036 using dbx_alloc_type+smash_to_pointer_type instead of
3037 lookup_pointer_type. I failed to find a justification for the
3038 former, so I changed it to use the latter. Similarly, I
3039 replaced smash_to_function_type by lookup_function_type,
3040 and smash_to_reference_type by lookup_reference_type.
3042 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3043 _initialize_mipsread): corresponding changes.
3045 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3047 * source.c (mod_path): Do tilde_expand on each component of the path,
3048 rather than on the (list of) paths as a whole.
3049 (print_source_lines): Set first_line_listed in addition to
3050 current_source_symtab and current_source_line. If the source was
3051 not findable, after a "dir" command to fix the problem,
3052 a "list" would get the wrong lines.
3054 While I was there... (gnu):
3056 * dbxread.c (read_type): Change error to complaint.
3058 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3060 First attempt at detailed understanding of symbol table memory alloc.
3062 * dbxread.c (dbx_symfile_read): Free our string table if we
3063 aren't the mainline. Free the "info" struct since we're done with
3065 (init_psymbol_list): Free any previously allocated psymbol lists.
3066 (): FIXME: Should realloc-down the psymbol lists when done reading
3067 the main symbol file?
3069 * symmisc.c (free_symtab): Free fullname field too.
3071 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3072 (REGISTER_ADDR): Make result type unsigned int.
3074 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3075 define REGEX must also define REGEX1 (its dependency).
3077 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3079 * tconfig/i960: No longer works, points you at vxworks960 or
3082 * xgdb.c, XGDB-README: Remove file. Users can get the much
3084 * Makefile.dist: Remove all trace of xgdb.
3086 * breakpoint.c (breakpoint_1): Pass demangle arg to
3087 print_address_symbolic.
3088 (clear_breakpoints): Remove unused function.
3089 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3090 (breakpoint_re_set): Use catch_errors to do them all anyway.
3092 * gdb-int.texinfo (Host versus Target): Add section on what is
3093 a "host" feature versus what is a "target" feature.
3095 * infcmd.c (path_command, path_info): Handle the PATH variable
3096 (object search path) as conveniently as the source search path.
3097 * environ.c (set_in_environ): Set some vars in GDB's environment,
3098 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3099 * source.c (mod_path): New function, from guts of
3100 directory_command, modifies a path. Used by path_command.
3101 (directory_command): Call it.
3102 * defs.h (strsave): Declare.
3104 * utils.c (sevenbit_strings): Add new printing option.
3105 (printchar): Use it.
3106 (strsave): Provide this handy helper routine.
3107 (set_width_command): Rename set_screen_width_command.
3108 (_initialize_utils): "set screen-width" => "set width";
3109 "set screen-height" => "set height"; add sevenbit-strings.
3111 * infcmd.c (do_registers_info): Print floating point registers
3112 in raw hex as well as float format, regardless of whether it is
3113 a "virtual" convertible register.
3114 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3115 regs as a double, just in case it's being used that way.
3116 * values.c (unpack_long): Comment on array/function coercion.
3117 (unpack_double): Argument is in target byte order now. For
3118 integer arguments, just call unpack_long and float the result.
3119 * m68k-tdep.c: include defs.h for "const" handling.
3120 * remote-nindy.c: Use ieee-float stuff.
3121 (nindy_fetch_registers): Unpack double regs to host double, then
3123 (nindy_store_registers): Pack extendeds to host double, flip
3124 around by misusing unpack_double, send as target double.
3126 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3127 zero, as when stopped at the first instruction of a process.
3129 * blockframe.c: Fix filename in comment (param.h => tm.h).
3130 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3131 * tm-68k.h: Fix typos.
3133 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3135 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3137 * coredep.c (fetch_core_registers): Pass end-address of register
3138 section to register_addr as expected. Don't call supply_register
3139 if we'd just pass it garbage.
3141 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3143 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3145 * target.c (push_target, target_info): Cast enums to int for < or
3148 * stack.c (print_frame_info): Identify source file & line
3149 even if we can't print it.
3151 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3153 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3155 Clean up IEEE floating point support.
3157 * ieee-float.h: New file.
3158 * ieee-float.c: Write real routines to convert between host
3159 doubles and various target IEEE extendeds.
3160 * m68k-xdep.c: Eliminate assembler code for extended floats.
3161 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
3162 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3163 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3164 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3165 double_to_ieee_extended.
3166 * i960-tdep.c: Define ext_format_i960.
3167 * m68k-tdep.c: Define ext_format_68881.
3168 * sparc-tdep.c: Define ext_format_sparc, though unused.
3169 * Makefile.dist (HFILES): Add ieee-float.h.
3170 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3173 Obsolete the "coffstrip" program in favor of using BFD's strip.
3175 * nindy-share/coffstrip.c: Remove file.
3176 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3177 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3178 * tconfig/nindy960: Remove reference to coffstrip.o.
3180 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3182 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3184 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3185 * dbxread.c: Remove static symfile_bfd.
3186 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3188 * inftarg.c (child_detach): Pop the child_ops vector if the
3189 detach is successful.
3190 * remote-nindy.c (nindy_create_inferior): Don't push a new
3191 nindy_ops since nindy uses the same one for execution and memory
3193 * core.c (core_ops): Use child_attach and child_create_inferior
3194 rather than default attach and create_inferior functions.
3196 Handle floating point registers in core files.
3198 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3199 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3200 This version untested since BFD doesn't yet support sun3 core
3202 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3203 conventions. Fix comments and style. This version has not
3204 been compiled yet, since we have no HP inhouse.
3205 * core.c (get_core_registers): Look for two sections, ".reg"
3206 and ".reg2", and pass both to fetch_core_registers sequentially.
3208 Revise directory path yet again.
3210 * source.c (forget_cached_source_info): Not static any more.
3211 (init_source_path): New default source path is "$cdir:$cwd".
3212 (dir_command): Handle variable arguments ($cdir, $cwd).
3213 (source_info): Print "Compilation directory" rather than
3214 "Originally compiled in" to remind people of $cdir.
3215 (openp): If the path contains $cwd, use current directory.
3216 (open_source_file): If compilation directory is known, replace
3217 first $cdir in path with the compilation directory.
3218 (print_source_lines): Even if we can't print the lines, set the
3219 current symtab and line for future commands like "info source" or
3220 "breakpoint". Also, error message now contains the file name,
3221 line number, and file access error message.
3222 (_initialize_source): Fix help text to describe changes.
3223 * main.c (cd_command): Forget cached source info when we chdir.
3224 * utils.c (strstr): Add simple implementation.
3226 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3228 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3229 Byte-swap COFF symbol tables if necessary when reading them in.
3230 Use complain() to replace error message in one spot. Needs
3231 corresponding change in bfd/coff-code.h to make some symbol
3232 swapping routines non-static.
3234 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3236 Merge changes from Eirik Fuller, for UTek.
3238 * defs.h (errno): Add declaration.
3239 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
3240 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3241 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3242 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
3243 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
3244 declarations of errno.
3246 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3248 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3249 <rpc/rpc.h> and <rpc/types.h>.
3251 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3253 * i960-tdep.c (examine_prologue): Add new argument limit,
3254 which stops the scan at the end of the prologue, or at the PC.
3255 This fixes a problem where it walks down into the code for the
3256 user's statements if that code looks like function prologues.
3257 Mark Fox and I have been bouncing this code back and forth, making
3258 small changes to it. Callers changed to match.
3260 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3262 Cleanup for gdb-3.94 release final:
3264 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3265 the .c files from vx-share and nindy-share, from the various
3266 macros, since they are not found via ALLDEPFILES.
3267 (SFILES): Add tm-i960.h.
3268 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3269 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3271 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3272 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
3274 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
3276 * am29k-tdep.c: Add contribution line.
3277 (examine_prologue): Cache information about function prologues in
3278 the misc-function-vector to avoid lots of references over the
3279 serial line while examining instructions.
3281 * core.c (core_close): New function made from cleanup_core.
3283 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3284 remote-vx.c, remote.c, target.c, target.h,
3285 Update target_ops vector to add attach, close, and load entries.
3286 Use add_syms_addr_command, not add_file_addr_command, for
3287 add_file. Break out close routine from existing code.
3289 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3290 they are in an obstack.
3291 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3293 (define_symbol): Add symbol type parameter; change callers;
3294 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3295 it to influence the symbol class on the i960.
3296 (define_symbol): Swap LOC_CONST's into target byte order.
3298 * exec.c (exec_close): New function.
3299 (exec_file_command): Call it.
3301 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3302 Fix byte order of frame pointer.
3303 (read_var_value): Result of 0 if var's value can't be found,
3304 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3305 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3306 (locate_var_value): Use read_var_value and use its lazy address
3307 as the location of the var's value. Lint.
3309 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3312 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3313 obsolete Intel versions in favor of vxgdb versions.
3314 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3315 code dealing with byte order of values, which Intel did in host byte
3316 order rather than gdb-4's target byte order.
3317 (i960_frame_chain_valid): Move to nindy-tdep.c.
3318 (examine_prologue, skip_prologue, frame_find_saved_regs,
3319 frame_args_address, leafproc_return, saved_pc_after_call,
3320 pop_frame): Add vxgdb versions from Mark Fox.
3321 (examine_prologue, frame_struct_result_address): Add code
3322 to deal with the saved value of G13 (struct return address
3324 (frame_args_address): Modify Mark's version to prefer the
3325 saved value over the current value in the topmost frame.
3326 Cache result in the frame info to avoid performance hair in
3328 (print_fault): Add gdb960 code for printing faults.
3329 (_initialize_i960): Actually call check_host.
3331 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3332 add stub routines. FIXME, these currently just return zero!
3334 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3335 (attach_command): Call target_attach, not target_open, now.
3337 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3338 (child_attach): Rename from child_open.
3339 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3340 don't confuse it with a zero step_resume_break_address.
3342 * inftarg.c (child_detach): Eliminate inferior_pid test.
3343 (child_files_info): Clean up message a bit.
3344 (child_ops): Use child_attach, not child_open, to attach.
3346 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3347 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3348 findvar.c to here, since it depends on the contents of the
3349 shadow_contents of breakpoints, but keep if #if 0 since it is
3352 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3355 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3356 (ptype_command, display_command): Eliminate have_inferior_p and
3357 have_core_file_p in favor of target_has_stack or
3358 target_has_execution.
3359 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3360 code for actually finding the values of arguments, though we still
3361 keep track of the maximum stack offset for use in printing unnamed
3362 arguments. Handle missing FRAME_ARGS_ADDRESS.
3364 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3365 (struct nindy_regs): Define registers passed to/from nindy.
3366 (nindy_fetch_registers, nindy_store-registers): Translate between
3367 nindy and GDB formats for the registers.
3368 (dcache_init): Statically allocate the cache, since it was being
3369 allocated by a malloc that was never freed anyway.
3370 (nindy_create_inferior): Error, not core dump, if no exec file.
3371 (nindy_before_main_loop): Use target_load, not target_add_file.
3373 * remote-vx.c (net_load): Specify large timeout for load
3374 requests. Allow user to break out with INTERRUPT.
3375 (net_break): Remove useless code, clean up. Change callers.
3376 (parse-args, skip_white_space, find_white_space): Clean up arg
3377 parsing to cope with quoted strings.
3378 (net_wait, net_quit): Never call error, just return status.
3379 (vx_read_register, vx_write_register): Cleanup status checking.
3380 #ifdef the code based on which CPU we are using (960 or 68k),
3381 FIXME, this should be completely general but it isn't yet.
3382 (vx_xfer_memory, vx_resume): Cleanup status checking.
3383 (vx_run_files_info): Improve message.
3384 (vx_load_command): Renamed from vx_add_file_command. Allow load
3386 (net_ptrace): Remove unused routine.
3387 (vx_wait): Adopt code from vxgdb960 to cope with broken
3388 connections to target machine and prompt to disconnect. Remove
3389 debug printouts. Map some EVENT_'s to SIGnals.
3390 (add_symbol_stub, vx_open): Print names of object files we found,
3391 and "ok" if we read their symbols OK. Clarify output in general.
3392 (vx_attach, vx_detach, vx_kill): Add these commands.
3393 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3394 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3395 "info files" output, and create_inferior, since we already have
3398 * stack.c (frame_info): Replace Frame_unknown with 0.
3399 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3400 (return_command): Pop until the PC matches as well as the FP,
3401 so it works even if the FP is shared with another function,
3402 as in "frameless" or "leaf" procedures.
3404 * symfile.c (load_command): renamed from add_file_target_command.
3405 (add_syms_addr_command): renamed from add_file_addr_command.
3406 (add_syms_command): Stub to call target_add_syms.
3407 (_initialize_symfile): Change command names and descriptions,
3408 add-file => add-syms, and load from alias to its own command.
3410 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3411 maybe_kill_then_create_inferior): Default for attempts to start
3412 a process, if one is already running, is to ask about killing
3413 it and retry if yes.
3414 (upstack_create_inferior): #if-0 it, strata obsolete it.
3415 (push_target, unpush_target, pop_target): to_close() a target
3416 before unstacking it.
3417 (target_info): Renamed from target_files_info.
3418 (_initialize_targets): Rename "i files" as "i target", accessible
3421 * target.h: Improve comments about the target_ vectored routines.
3423 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3424 Convert commenting style to standard GNU style.
3425 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3426 (SKIP_PROLOGUE): No longer a no-op.
3427 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3428 (*_REGNUM): Sort register numbers.
3429 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3430 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3431 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3432 are now 10 byte extendeds, not 8 byte doubles.
3433 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3434 for nindy versus vxworks targets. FIXME, this should possibly go
3435 in the target vector.
3436 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3437 frame_saved_regs and arg pointer with each frame.
3438 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3439 (FRAME_ARGS_ADDRESS): Use cached result.
3440 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3441 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3442 (PRINT_RAMDON_SIGNAL): Call print_fault.
3443 (POP_FRAME): Now works.
3445 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3446 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3447 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3448 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3451 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3452 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3454 * valarith.c (value_subscripted_rvalue): Avoid handling
3455 floats and doubles specially; it gave alignment errors. Lint.
3457 * valops.c (value_of_variable, value_of_this): Error if unknown
3460 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3461 to avoid alignment problems.
3462 (value_print): Handle unknown value address.
3463 (cplus_val_print): Two args are ignored; remove them. Change caller.
3464 (val_print): Use unpack_long rather than pointer-deref.
3467 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3468 to avoid alignment problems.
3469 (value_being_returned): Error if return value unknown.
3470 (set_return_value): Add bogosity warning, FIXME. *
3472 * TODO: A woman's work is never done.
3474 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3475 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3476 Add ieee-float.o to OBS.
3477 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3478 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3479 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3481 Changes to generalize the VxWorks RPC protocol slightly, to handle
3482 i960 as well as 68000.
3484 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3485 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3486 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3487 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3488 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3489 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3490 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3491 so they will move in target byte order rather than network
3492 byte order (happens to be the same).
3494 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3496 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3498 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3501 Add contribution lines to various files, showing where they
3504 * breakpoint.c (break_insn, check_break_insn_size,
3505 read_memory_nobpt): Remove to mem-break.c.
3507 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3510 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3511 entry has bad register number. This change is not
3512 tested in this release, FIXME.
3514 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3517 * value.h: Force value's contents field to be aligned to hold
3518 at least a double or a long long (if supported). This avoids
3519 doing bcopy's in and out of the contents field.
3521 (step_1): Avoid coredump under obscure circumstances when we
3524 * symtab.h (misc_info): Add field to misc function vector for
3525 any kind of cached information the target code desires. AMD
3526 29000 uses this to avoid repeating examine_function_prologue's.
3528 * coffread.c: Lint. Remove static symfile, read_section_header.
3529 core.c (have_core_file_p): Lint: remove.
3530 expprint.c (print_subexp): Lint.
3531 infptrace.c, valops.c, valprint.c: lint.
3533 Roll in changes from vxgdb-5.0.1:
3535 * symtab.h: Comment byte order of each address class. Add
3536 LOC_LOCAL_ARG for frame-relative args (960).
3537 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3538 symtab.c, symmisc.c: ditto.
3540 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3542 * remote.c (remote_resume): Error if resume with a signal.
3544 * symfile.c (prim_record_misc_function): Clear misc_info.
3545 (fill_in_vptr_fieldno): Check stub type of arg.
3547 * valops.c (value_cast): Avoid looking up names of types whose
3548 name we don't know, to prevent coredump. Sun CC produces typedef
3549 rtx and the name of *rtx is zero...
3551 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3553 Roll in changes from final AMD 29000 port (Tiemann).
3555 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3556 for ../include/a.out.encap.h. This might not work now that BFD
3557 is separately compiled. Instead, BFD support for encap will have
3558 to translate machine type 29k into the right COFF_MAGIC.
3560 * infcmd.c: Remove references to inferior_pid that aren't used
3561 in actual ptrace calls; use target_has_execution, etc.
3562 (have_inferior_p): Remove function.
3563 (program_info): Print target info rather than "process number";
3564 avoid gratuitous messages unless from_tty.
3565 (run_stack_dummy, finish_command): Set proceed_to_finish.
3566 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3567 main.c: Lint. Lose have_inferior_p().
3568 inferior.h (have_inferior_p): Remove, lint.
3569 (proceed_to_finish): Add flag to ask that all regs be saved
3570 by normal_stop, for the few commands that need it, speeding up
3571 serial I/O. Add comments to stop_registers.
3573 * remote-eb.c: Remove newline from breakpoint message we grep
3574 for. Never time out when running the user program.
3578 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3580 Roll in changes from vxgdb-5.0.1:
3582 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3583 symbol in its raw form, we are processing an unlinked ".o" file.
3584 See if the target environment has assigned it an address, using
3585 target_lookup_symbol (VxWorks does), and enter it into the symtab
3588 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3589 68k versions for a simpler version that assumes zero FP at bottom.
3590 Fixes bug of truncated stack reports.
3592 * target.h (target_lookup_symbol): Define this routine's args
3593 and result, finally.
3595 * target.c (nosymbol): Default routine for target_lookup_symbol.
3596 (target_default): Default lookup_symbol and call_function too.
3597 (files_info): Only print has_all_memory warning if a non-dummy
3600 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3601 vx_convert_from_virtual): If target does not have floating point,
3602 zero register "values", and avoid doing cross-net conversions.
3603 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3604 (vx_open): Rearrange code that attaches to target and reads
3605 symbols for all loaded modules, to work if some of the modules
3606 are not accessible. Add symbol_stub() and add_symbol_stub()
3607 as callbacks from catch_errors(). Allow connect attempt to be
3608 interrupted painlessly with ^C (FIXME, there are still some bugs
3609 if the interrupt happens during symbol reading.). Print
3610 final message with puts_filtered, since symbol messages are
3615 * main.c (catch_errors): Only print errstring if non-null.
3616 (command_loop): Avoid an ioctl per command to test ISATTY.
3618 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3619 (vx_xfer_memory): Return correct result!
3620 (vx_files_info): Indicate whether target has float or not.
3621 (vx_lookup_symbol): Complain, not error, if target gone.
3622 (vx_open): Print "Connected" msg before disabling immediate-quit.
3623 [FIXME: lookup_symbol and vx_open changes need testing.]
3625 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3626 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3627 contributor lines and update copyrights to 1991.
3629 Changes from an attempted H-PUX host port:
3631 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3632 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3633 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3634 * remote-vx.c: include <sys/time.h> for HPUX.
3635 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3636 "core_file_command" routine to BFD regime. May not work yet.
3638 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3640 * xgdb.c: Replace X10 version with some VJ version.
3641 (FIXME: Its copyright assignment is not on record.)
3642 * xgdb.c: Update include files to X11R4 (Xaw crud).
3643 (xgdb_display_source, create_text_widget): fix call to
3644 get_filename_and_charpos. Rewack source window stuff for X11R4
3645 (gleaned from include files, and "nm's" of binary libraries, since
3646 I had no doc available).
3647 (append_selection, append_selection_word): Disable with FIXME
3648 since R4 changed interface here.
3649 (create_buttons): Add back the old set of buttons.
3650 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3652 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3653 Roll VERSION to 3.94 (not yet final though).
3655 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3657 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3658 obstack_int_grow, obstack_int_grow_fast): Eliminate
3659 cast on left of assignment, which gives MIPS cc fits and is
3662 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3663 F_ALIAS. Use printf, not fprintf, when not passing a file
3665 (compare_opcodes): Check that identical instructions have
3666 identical opcodes, complain otherwise.
3668 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3669 was reported by Roland McGrath.
3670 (unimp): Only match if exactly zero instruction. (Roland)
3671 (branches and traps): Generate all variations of these
3672 instructions with macros, based on a single call that defines
3673 each condition name and its binary representation.
3674 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3676 * valprint.c (val_print_fields): Take, and use, format parameter.
3677 This means that "p/x struct" again prints the elements in the
3678 desired format. Changed callers.
3680 * stack.c (frame_info): Use filtered output, and indicate wrap
3681 points. Remove kludgy formatting designed to avoid line wrap.
3683 * utils.c (wrap_here): If the line is already full (because
3684 we had printed a long indent or long wrapped string), do an
3685 immediate newline-and-indent.
3687 * m68k-pinsn.c (print_insn_arg): Bugfix from
3688 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3689 instruction is incorrectly disassembled as bkpt #8.
3691 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3692 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3693 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3694 and then will dump core (sometimes). I traced it back to an
3695 uninitialized symfile_name in psymtab_to_symtab.
3696 (const_vol_complaint): Add quotes to message.
3697 (define_symbol): Only believe line number if gcc_compiled.
3698 Avoid allocating symbol if we will not return it.
3700 Add target strata support so that newly established targets go
3701 into their right place in the target stack (e.g. a new exec file
3702 doesn't wipe out the ability to access the running process).
3704 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3705 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3706 and initialize it properly in all the targets.
3708 * target.h: Document strata. Change return type of push_target.
3710 * target.c (nomemory): new function for dummy memory access.
3711 (tcomplain): Rename complain, now also used in symfile.c.
3712 (push_target): Push targets within strata. New return value shows
3713 whether new target is on top of stack or not. Always keep dummy
3715 (target_files_info): Ignore dummy target.
3717 * core.c (core_open): Warn user, and skip accessing file, if the
3718 core target is not the topmost target in the stack.
3719 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3722 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3723 target_ops, it doesn't belong there since we have no regs there.
3724 Change name of target from machine => memory to clarify.
3726 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3728 * Freeze version 3.93 for release.
3730 * Makefile.dist: Handle vx-share and nindy-share subdirs
3731 properly when building gdb.tar.Z.
3733 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3734 printed in various places, so I could change just one copy.
3736 * dbxread.c, coffread.c: Change references to bfd->iostream
3737 to cast to FILE *, now that BFD avoids needing types defined
3738 in other header files.
3740 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3742 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3743 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3744 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3745 (actually gcc -Wall).
3747 * dbxread.c: Remove first_global_sym, last_global_sym, since
3748 they are never referenced.
3750 * defs.h (baud_rate): Declare.
3751 main.c: Define it, and add the -b option to set it.
3753 * gdb-int.texinfo: Add text on how to define a new host or target
3754 architecture, prompted by Per Bothner's questions about MIPS
3757 * gdb.texinfo: Document "complaints". Change doc of -q since
3758 gdb no longer prints the copyright and blurb if you specify a file
3759 name to be debugged (just like Emacs). Add doc for Nindy-specific
3760 command line flags for specifying target serial port and such.
3761 Update copyright to 1991.
3763 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3764 has taken over for us the job of ripping up executable files. The
3765 crud caused Per Bothner's port to not compile.
3767 * infrun.c (normal_stop): Avoid printing "Program exited
3768 normally" if we are in batch mode. This allows a GDB which
3769 executes a program on a target system, to behave like a Unix
3770 command (input from stdin, output to stdout, no extraneous
3773 * main.c (main): Allow additional machine-dependent command line
3774 options to be specified with the ADDITIONAL_OPTIONS,
3775 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3776 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3777 processing to occur just before the main loop with
3778 BEFORE_MAIN_LOOP_HOOK.
3779 (main): If a "core file" argument is specified, and it is not a
3780 core file, try it as a process ID to attach.
3781 (symbol_completion_function): Attempt to cope with
3782 "show screen-" TAB, not very successfully. This needs more work,
3784 (batch_file): New function, returns whether we are reading
3785 commands from an interactive tty on stdin, or from somewhere else.
3786 Called by normal_stop since it doesn't get from_tty passed down
3787 to it like many commands do.
3789 * remote-nindy.c: Handle command line options for nindy
3791 (nindy_before_main_loop): Prompt user for tty name if they
3792 don't specify it before getting to the interactive command loop.
3794 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3795 and -r command line options. Also add hook before main loop
3796 to make it easy to specify a tty.
3798 * TODO: More things to do, one done.
3800 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3802 * dbxread.c: Make complaint() calls pass pointer, not struct.
3803 Add complaints about badly formatted C++ type information
3804 (const/volatile indicator, and parse errors resulting in
3805 error_type). Fix C++ virtual member fn comment.
3806 (read_struct_type): Avoid bumping pointer if we got a parse
3807 error; this prevents our walking beyond the end of a string.
3808 Terminate loop on null char as well as semicolon.
3809 (process_one_symbol): Fix the LBRAC fix so that it uses the
3810 last previous SLINE, FUN, or SO record's PC address. C++ debug
3811 symbols did not have SLINE records in a useful order compared
3812 to the LBRAC records.
3813 (define_symbol): Handle "catch" records.
3815 * symtab.c (check_stub_type): Added new complain
3816 `stub_noname_complain' and added a consistency check to
3817 keep the debugger from crashing when finishing from an
3818 exception frame. A real fix will be needed later.
3820 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3822 * infcmd.c (attach_command): Make global.
3824 * Makefile.dist (REMOTE_OBS): Make these compile by default,
3825 but make them easy to comment out. Perhaps later they should
3826 be enabled by what CPU you configure for? FIXME.
3827 (VERSION): Roll to 3.93.
3828 (pinsn.o): Remove rule for obsolete file.
3829 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
3831 Run down a problem that manifested by printing the wrong function
3832 name in stack traces of read_ofile_symtab. Turned out that the
3833 problem was the SunOS 4.1.1 (and previous) C compiler outputs
3834 the LBRAC symbol with an address in the *data* segment, which
3835 blew our binary search through the blocks.
3837 * dbxread.c: Use the complain() facility consistently to bitch
3838 about problems in the symbol file we are reading.
3839 (finish_block): Add code to check the nesting of the blocks;
3840 complain and Procrust them to fit if wrong.
3841 (make_blockvector): Check the order of the blocks, complain
3842 [but don't cope] if wrong.
3843 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
3844 symbols to be sure their PC value is greater than the last SLINE
3845 (line number) symbol we've seen, complaining and adopting the
3846 SLINE PC value if wrong.
3848 * symfile.h (struct complaint, complaint_root, complain,
3849 clear_complaints): Add.
3850 * symfile.c (complain, complaint_root, clear_complaints): Add
3851 facility to deal with non-fatal complaints and to regularize their
3853 (symbol_file_add): Clear complaint counters to allow new complaints.
3854 (initialize_symfile): Add 'set complaints' and 'show complaints'.
3856 * dbxread.c (dbx_symfile_read): Remember the address and size
3857 of the string table for the main symbol file, so we won't read it
3859 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
3860 to avoid reading the string table yet again. Lint.
3861 (throughout): Improve filtered output, including word wrap.
3862 (read_range_type): Improve Bothner's fix to handle other types too.
3864 * utils.c: Improve line wrap implementation. Handle unlimited
3865 width by making chars_per_line unsigned.
3866 (puts_filtered): New, easy, function.
3868 * defs.h (puts_filtered): add.
3870 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
3871 call the identical sort_symtab_syms() in symfile.c instead.
3873 * expread.y: Suggest the `file' command rather than `symbol-file'.
3875 * command.h (enum var_types): Add zinteger for seroable
3877 * command.c (do_setshow_command): Handle var_zinteger. Restructure
3878 nested if's into a switch.
3880 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
3881 we did not stop because of a breakpoint (it must have been for
3882 some other reason, like a "stepi"), so don't print anything.
3884 * symtab.c: Include <sys/types.h> all the time. Now that BFD
3885 doesn't include <sys/types.h>, old SunOS's require it for
3888 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
3890 A test port of gdb-3.92.6 to the Sony NEWS.
3893 Don't normally link in remote- or vx stuff.
3894 Some of it doesn't compile, and it wastes space for 99% of the users.
3895 Remove reference to no-longer-used HAVE_VPRINTF.
3896 Fixed BFD_DEP typo to BFD_DIR.
3898 Fix cast in arg to bfd_h_getlong.
3899 Make char *prefix be const.
3900 Fix how certain range types are mapped into builtin unsigned int types.
3902 Remove 2 #includes. They cause errors (on Sony, at least),
3903 and aren't needed (they wern't in earlier versions).
3905 print_address_symbolic should never demangle labels
3906 (since it prints *assembler-level* labels).
3908 [This was superseded by the change to printcmd below.]
3911 Add some "volatile" return types to avoid warnings.
3912 If MISSING_VPRINTF add vprintf function and not just macro
3913 (since vprintf is used in printcmd.c).
3915 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
3916 (The latter isn't grokked by some PCC-based compilers.)
3918 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
3920 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
3921 * nindy-share/coffstrip.c
3922 Added some forward declarations (otherwise, gcc complains
3923 about implicit extern redefined as static).
3925 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3927 Changes inspired by Per Bothner:
3928 * printcmd.c (print_address_symbolic): Take additional parameter
3929 specifying whether to demangle.
3930 (print_address): Pass in asm_demangle to control demangling.
3931 (print_address_demangle): New fn, takes explicit arg to control
3933 * utils.c: Add new vars demangle and asm_demangle, and let them
3935 (fputs_demangled): If !demangle, just print the argument.
3936 (fprint_symbol): If !demangle, just print raw symbol.
3937 * valprint.c (val_print): Call print_address_demangle rather than
3938 print_address, to cause demangling to depend on the global
3939 rather than assembler-level demangling setting.
3940 * WHATS.NEW, gdb.texinfo: Document.
3942 * main.c (show_command): Show all settings if no arg.
3943 (initialize_main): Make "info set" the same as naked "show".
3944 * command.c (cmd_show_list): Handle prefix commands in the
3945 list, and print the name of the setting as well as its English
3946 description and value.
3948 Allow gdb functions to specify where a line should wrap if it
3949 exceeds the size of a terminal line. Use it to make the output
3951 * utils.c (set_screen_width_command): New fn, mallocs a buffer
3952 of the right size when screen width changes.
3953 (set_screensize_command, screensize_info): Remove #if 0'd fns.
3954 (wrap_here): New fn, indicates a point in the output where we
3955 should wrap the line rather than just letting it overflow at a
3957 (fputs_filtered): Implement wrapping.
3958 (n_spaces): New fn, returns a pointer to N spaces.
3959 (print_spaces_filtered): Use n_spaces.
3960 * defs.h (n_spaces): Declare.
3961 * stack.c (print_frame_info): Wrap with 4-space indent after
3962 fn name and before filename and line number.
3963 * printcmd.c (print_frame_args): Wrap with 4-space indent
3964 before each argument name is printed.
3965 * valprint.c (value_print): Wrap with no indentation before
3967 (val_print_fields): Wrap with indentation relative to nesting
3968 level before each field name.
3969 (val_print): Wrap with nesting indentation before array elements.
3970 * command.c (do_setshow_command): Avoid extra newlines,
3971 wrap with 4-space indent around values printed, end with period.
3972 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
3974 * breakpoint.c (breakpoint_1): Implement addressprint for
3975 "info breakpoints" display. Change file name and line number
3976 format to " at file:nnn" rather than " (file line nnn)".
3977 * gdb.texinfo: Document.
3980 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3982 Frozen for gdb-3.92.6 release.
3984 README, WHATS.NEW: Update for 3.92.6 release.
3986 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
3987 coffread.o from configs since it is now built by default.
3988 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
3989 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
3990 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
3991 from configs since it is now built by default.
3993 Makefile.dist: Update for release 3.92.6. Handle files that
3994 have been moved to ../include, ../getopt, or ../bfd. Add
3995 saber.suppress and tests directory. Add config.status to
3996 the release (it will say "none").
3998 coredep.c: Minor formatting fixes.
4000 These changes were made in early December but only checked in now:
4001 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4002 nindy-share/nindy.c: lint
4003 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4004 register values coming back from the target; we store values
4005 in target byte order everywhere.
4007 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4009 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4011 * valprint.c (cplus_val_print, val_print_fields): New functions,
4012 which print C++ objects. They conspire to avoid printing a
4013 virtual base class more than once, following all the twists and
4014 turns of C++ virtual base rules.
4015 (val_print): Call the above rather than do it by hand.
4017 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4018 symbol file, not for added files like shared libs. This really
4019 needs to be generalized to a timestamp per file.
4021 * core.c (cleanup_core): Avoid coredump if no core file.
4023 * config.gdb: Accept -host or -target in place of +host or
4026 * coffread.c (find_linenos): Avoid desupported BFD interface
4027 to line numbers. We still read them manually rather than using
4028 BFD's "generic" features.
4030 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4032 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4034 * Makefile.dist: Eliminate use of $< in explicit targets.
4036 * readline/Makefile: Use $< rather than $*.c, which does not
4037 include the VPATH in GNU Make.
4039 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4040 copies of tconfig/i960, added for global configuration
4041 compatability. All i960 versions can read both coff and b.out.
4043 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4044 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4047 * TODO: Think of more things to do.
4049 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4051 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4052 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4053 64-bit float conversion.
4055 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4056 equivalent to sun?os4 so global config works.
4058 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4060 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4062 * main.c: Only declare linesize once; declare pagesize not at
4063 all, since it is never used.
4064 (main): Clear newly allocated line before it is used.
4066 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4068 Further stabilization for the Intel 960.
4070 * Makefile.dist: Parameterize the location of the "include"
4071 and "bfd" directories, as well as "getopt". Add symfile.c.
4072 Link in both dbxread and coffread. Fix up "make depend" to
4073 rewack the locations of include, bfd, and getopt in its output.
4075 * README: Document moving include files, improve some of
4078 * coffread.c: Move common code out to symfile.c. Change
4079 symbol_file_command style interface to use new *_symfile_init
4080 and *_symfile_read interface under BFD. Use BFD internal
4081 info to locate line table, symbols, etc.
4083 * core.c (core_fetch_registers): Rename to get_core_registers
4084 to avoid confusion with fetch_core_registers.
4085 (register_addr): Move to coredep.c, which is already machine
4086 dependent. This leaves core.c pretty clean of dependencies.
4088 * coredep.c (register_addr): Accept this routine from core.c.
4090 * dbxread.c: Move common code (with coffread.c, etc) into new
4091 symfile.c. Each psymtab now contains a pointer to the
4092 format-dependent function that knows how to read it in. Make
4094 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4095 (process_one_symbol): Add code to complain about a "compiler bug
4096 we muzzle here", if we actually see it.
4098 * eval.c (evaluate_subexp): Insert missing "break" statements
4099 in code that determines whether a variable is an lvalue in
4100 memory, register, or whatever. I detected this via a compiler
4101 bug in which it *almost* mashed out the whole switch statement.
4103 * gdb-int.texinfo: Add minor sections on configuring gdb for
4104 release, and about the README file.
4106 * infcmd.c (registers_info): Fix formatting somewhat. Still
4107 not as pretty as before, but it handles byte swapping.
4109 * remote-nindy.c: If data cache routines are interrupted while
4110 waiting for the remote end, be sure that any uninitialized cache
4111 blocks are on the free list, not on the valid list!
4113 * symfile.h: Flesh out this header file with all the various
4114 routines and variables that have been merged in from dbxread.c
4115 coffread.c, and symtab.c to symfile.c.
4117 * symfile.c: New file, containing code common to dbxread.c,
4118 coffread.c, and some code from symtab.c. All generic code for
4119 reading symbol files should be in here now.
4120 (unrecord_misc_function): Remove unused function.
4122 * symtab.h: Remove file-reading things to symfile.h.
4124 * symtab.c: Remove file-reading things to symfile.c.
4126 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4127 to decode i960 fault types.
4129 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4130 target.c: Change type of the "resume" function from int to void,
4131 since its result was never used.
4133 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4135 * main.c: Replace "stupid" with "caution"; you now "set caution
4138 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4140 * infcmd.c (do_registers_info): Call val_print to deal with the
4141 byte order of the registers being printed. FIXME, this makes
4142 the formatting of the output uglier.
4144 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4145 defined, call it for signals the debugger doesn't itself use.
4146 The i960 uses this for more detailed fault information.
4148 * remote.c (remote_open): If arg is null, print help rather than
4151 * sparc-xdep.c (register_valid): Avoid declaring size, since
4152 various modules will think of various sizes depending on the
4153 architecture of their tm-file. FIXME, we need protection against
4154 actually entering one of those modules, which would clobber
4155 storage if not for the target architecture compiled into gdb.
4157 * stack.c (up_command, down_command): Always print the frame
4159 (up_silently_command, down_silently_command): New commands
4162 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4164 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4165 more parameters than it used to.
4167 * findvar.c (registers): Increase slop to 256 bytes, which should
4168 protect us against even most RISC machines with large register
4170 (locate_var_value): Move declaration inside related ifdef.
4172 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4173 throughout, to avoid throwing away buffered input from the board.
4174 (nindy_wait): Supply_register takes addr_of_value, not value.
4175 (i960_print_fault): Renamed from i80960_fault.
4176 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4177 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4179 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4180 we can set the PC in the call to proceed(). Unpush nindy_ops
4181 before pushing it on top, to avoid message to user. Eliminate
4182 commentary from Unix machines that just misleads here.
4183 (reset_command): Fix error message to suggest target command.
4185 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4187 Release 3.92.5 as frozen.
4189 Stabilize the merged release...with help from lint, Saber C,
4192 Everywhere: Add include files needed to declare return types
4193 of functions called.
4195 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4197 * breakpoint.h: Add undeclared breakpoint functions, and some
4198 functions for display handling since I couldn't think of a better
4201 * breakpoint.c (insert_breakpoints): Make code for disabling
4202 shared library bkpts more likely to work. It's used when we
4203 rerun a program and stop before the shared library has been
4205 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4206 cast from pointer, so it squeezes through catch_errors.
4207 (bpstat_stop_status): Fix logic broken some time ago. We now
4208 always create a bpstat if the stop address matches a breakpoint,
4209 even if we don't stop there -- just like the old code used to do
4210 before I got my fingers into it (sigh).
4211 (breakpoint_1): Print "ignore count" after "stop only if"
4212 condition, since that's how it actually works.
4213 (mention): Handle watchpoints as well as breakpoints.
4214 (watch_command): use set_raw_breakpoint and mention to do most
4215 of the work (and initialize all the fields!). Only pass one
4216 arg to parse_c_expression, since that's all it takes.
4218 * command.c (not_just_help_class_command): Rename arg to args
4219 since we ignore "unused argument" warnings on vars named "args".
4220 inflow.c (child_terminal_info): ditto.
4221 infptrace.c (kill_inferior): ditto
4222 main.c (catch_errors, version_info, quit_command, pwd_command,
4223 source_command, dump_me_command, editing_info,
4224 set_history_size_command, set_history, show_history,
4226 stack.c (locals_info): ditto
4227 target.c (target_files_info): ditto
4228 valprint.c (set_input_radix, set_output_radix): ditto
4230 * core.c: Remove old variables for handling core and exec file
4231 sections (data_start, data_end, stack_start, stack_end,
4232 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4233 text_end, exec_data_start, exec_data_end, text_offset,
4234 exec_data_offset, data_offset, stack_offset). They're
4235 superseded the more general build_section_table and
4237 (get_exec_file): Mention the `file' command.
4238 (read_memory_check): Rename to memory_error, and only call it
4239 in the case of an actual error.
4240 (read_memory, write_memory): call memory_error.
4241 (core_fetch_registers): Register section name is ".reg".
4243 coredep.c: Remove a bunch of crud now that all this file does
4244 is pull the registers out of a core file.
4245 (fetch_core_registers): Rewrite to actually work, I hope.
4247 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4248 Replace index() with strchr(). Remove all the pre-BFD macro
4249 definitions for accessing the symbol file.
4250 (struct dbx_symfile_info): Encapsulate the information that
4251 dbx_symfile_init needs to pass to dbx_symfile_read in this
4254 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4255 dbx_symfile_discard): Rearrange symbol file reading to divide
4256 the format-specific part from the format-independent part,
4257 leaving the format-independent part such as file name expansion
4258 and opening in symtab.c. This replaces
4259 partial_symbol_file_open and partial_symbol_file_read.
4260 Symbol_file_read, add_file, add_file_target_command,
4261 add_file_addr_command move to symtab.c. Pass an explicit
4262 "mainline" flag for when reading the main symbol table, rather
4263 than relying on the offset address to be zero or nonzero.
4265 (dbx_symfile_read): Don't allow void *'s to be printed as
4267 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4268 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4269 macro" debug version really work.
4270 (read_dbx_symtab): Remove unref'd parameter inclink.
4271 Avoid swapping N_SLINE symbols, for speed.
4272 Merge N_TEXT!N_EXT case with the other external symbol
4273 definitions' case. Add comments.
4274 (start_psymtab): Allocate the symfile name in the psymtab on
4275 the psymbol_obstack, rather than using the caller's storage.
4276 (end_psymtab): Only allocate a dependencies list if there are
4278 (psymtab_to_symtab_2): Use BFD when reopening file to read
4279 its symbols for real.
4280 (read_struct_type): Add FIXME comments where it needs work
4282 (read_huge_number): Add FIXME about overflows.
4283 (read_range_type): Add FIXME about comparing a long to 1<<32.
4285 * coffread.c: Minor changes to move things closer to the new
4286 regime with symtab.c and dbxread.c Major work is still needed
4289 * exec.c (exec_file_command): Remove old variables (see core.c
4291 (xfer_memory): If memory transfer is right at the end of a
4292 section, don't lose.
4294 * findvar.c (get_saved_register): If value is in a real
4295 register, LVAL is lval_register, not lval_memory.
4297 frame.h: Declare print_sel_frame and record_selected_frame.
4299 gdb-int.texinfo: New file, for GDB internals documentation.
4300 Very simple, unformatted doc of cleanups is there for now.
4302 gdbcore.h: Remove obsolete variables that described a.out
4303 section addresses and offsets. (See core.c above.)
4304 Declare fetch_core_registers and registers_fetched.
4306 getopt.c: Declare char *alloca(); even on SPARC.
4308 infcmd.c (run_command): Call target_kill rather than
4310 (step_command, next_command, stepi_command, nexti_command):
4311 Declare from_tty parameter even though we don't use it.
4312 (run_stack_dummy): argument BUFFER is a char array, not
4313 a pointer to REGISTER_TYPE.
4314 (finish_command): using_struct_return needed a value *,
4315 not a struct symbol *.
4317 * infptrace.c (child_xfer_memory): To avoid dependency on
4318 where sections are in memory, try PT_WRITE_D and if that fails,
4319 try PT_WRITE_I. Most Unixes don't care which you use.
4321 * infrun.c (step_resume_break_shadow): Change to array to
4322 match other breakpoint shadow storage.
4323 (clear_proceed_status): Pass address of bpstat to
4324 bpstat_clear, not the bpstat itself.
4325 (child_create_inferior): FIXME comment about if the child
4327 (start_inferior): Remove old function.
4328 (child_open): Use target_kill rather than kill_inferior.
4329 (wait_for_inferior): Ditto.
4330 (insert_step_breakpoint, remote_step_breakpoint): Use
4331 new step_resume_break_shadow.
4333 * inftarg.c (child_wait): If all child processes die,
4334 pretend that the one being waited for exited with signal 42.
4336 * main.c (command_line_input): When scanning for comments,
4337 don't coredump on unclosed quotes.
4338 (quit_command): Use target_kill rther than kill_inferior.
4339 (_initialize_main): Rename class_user from "user" to
4342 * printcmd.c (print_command_1): Initialize "fmt" if no format
4343 is specified by the user.
4344 (print_frame_args): Only add to args_printed if we are
4345 actually fetching args from the stack (avoiding undefined
4347 (_initialize_printcmd): Remove bogus \{ from string.
4349 * remote-eb.c (eb_open): Avoid coredump on no argument.
4351 * remote-nindy.c: Bring out of Intel environment into new
4352 target environment. Remove all conditional compilation on
4353 I80960. Massive hacking throughout.
4354 (nindy_xfer_inferior_memory): New routine stolen from
4356 (nindy_create_inferior): New routine pieced together, probably
4357 not quite working yet.
4358 (nindy_ops): New target_ops struct for nindy.
4360 * remote-vx.c: Use write_memory rather than target_write_memory
4361 to get error checking.
4362 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4364 (vx_create_inferior): Use target_terminal_ours...
4366 * signame.c (_initialize_signame): Always initialize, since
4367 we need the table for things other than psignal.
4369 * solib.c (solib_add): Use symbol_file_add, not add_file.
4370 (solib_address): Return boolean result rather than struct
4371 pointer which nobody else knows the type of.
4373 * sparc-tdep.c, valops.c: Use write_memory rather than
4374 target_write_memory, to get error checking.
4376 * stack.c (locals_info, catch_info, args_info,
4377 get_selected_block, frame_command, up_command): Use
4378 target_has_stack, rather than have_inferior_p or
4381 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4383 * symfile.h: New file, defining the interface between the
4384 generic and object-file-specific symbol reading code.
4386 * symtab.c: Move generic symbol-reading interface to symtab.c,
4387 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4388 table to map BFD targets to symbol-reading modules in GDB.
4389 Change index to strchr.
4390 (lookup_struct_elt_type): Use error() rather than hand-made
4391 simulations thereof.
4392 (lookup_partial_symbol): Speedup slightly when length == 0.
4393 (symbol_file_add): New function.
4394 (symbol_file_command): Call it.
4395 (symfile_open, symfile_init): New function.
4396 (add_file_target_command, add_file_addr_command): moved from
4399 * target.c (target_command): use target_kill.
4401 * target.h (target_files_info): Don't declare, never called
4404 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4405 files to determine stack end address.
4407 * valarith.c (value_x_binop, value_x_unop): Change error message
4408 to be more useful. Pass proper argument to value_struct_elt.
4410 * valops.c (value_assign): FIXME comment that long long
4411 bitfields will break here.
4413 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4414 Update `make saber_gdb' to work better.
4416 * TODO: A woman's work is never done.
4418 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4419 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4420 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4421 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4422 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4423 valops.c, valprint.c, exec.c: Lint.
4426 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4428 Continuing Intel 960 port merge of GDB.
4430 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4431 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4432 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4433 Wack over "make depend" so it handles files in subdirectories
4434 vx-share, nindy-share, bfd, and in the current directory.
4436 * blockframe.c (get_prev_frame_info): Remove fatal error
4437 if stack not defined.
4439 * core.c (core_open, core_detach): New functions that handle
4440 the old "core-file" command as "target core" and "detach" instead.
4441 (core_file_command): Call them.
4442 (core_xfer_memory): Use common routine xfer_memory.
4444 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4445 dbxread now uses bfd for everything but symbol reading itself.
4446 BFD internals are used to drag out the relevant file offsets.
4447 (partial_symbol_file_open): Change args all around for BFD.
4449 * symtab.c: Rename "value" to "val" everywhere, so we can
4451 (symbol_file_command): New command, moved from dbxread.c
4452 and coffread.c. It uses BFD to read the file, then vectors
4453 based on its type, to dbx or coff symbol readers.
4454 * symtab.h: Extern a few vars for symbol_file_command.
4456 * target.h: Breakpoint takes a char * save area, not a char **.
4458 * valprint.c (val_print): When unpacking bitfields, offset
4459 the address in gdb of the value, if it is declared with a shorter
4460 type. Remove the last "runtime kludge test" of host byte order.
4462 * utils.c: Remove old my_bfd_read routine.
4464 * stack.c (frame_info): Use target_has_stack. Print program counter
4465 register's actual name rather than "pc", since it's called the
4466 "ip" (instruction pointer) on the i960 (sigh).
4468 * target.c (target_command): Add command for selecting a target
4469 type and calling its open routine. This is used for initiating
4470 communication with a particular target, in a generic way.
4472 * tm-i960.h: Update for modern gdb. Remove semicolons from
4473 various macros. Handle reading struct return convention, and
4474 error-out attempts to return structs with the "return" command.
4475 Be sure gdb doesn't think we know how to call functions in the
4478 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4479 to i960_xxx in lower case.
4480 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4481 not being defined yet.
4483 * remote.c (remote_open): Call start_remote to initialize
4484 wait_for_inferior during open.
4485 (remote_xfer_inferior_memory): Return length written rather
4488 * remote-vx.c (target_command -> vx_open): Use new generic
4490 * remote-eb.c, inftarg.c, exec.c: ditto.
4492 * infrun.c: Fix comments.
4493 (attach_program -> child_open): Use new generic target command.
4494 (wait_for_inferior): Clear saved register values before target_wait,
4495 so target_wait can set some of them if convenient.
4497 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4498 Return success indicator, not void.
4499 (child_xfer_memory): Avoid fetching initial word if we'll
4500 overwrite it anyway.
4502 * infcmd.c (attach_command): Use new generic target open routine.
4503 (_initialize_infcmd): Update doc on attach and detach commands.
4504 (do_registers_info): Merge in a byte-order problem as a FIXME
4507 * findvar.c (find_saved_register): Avoid problem in current frame.
4508 (read_relative_register): Ditto.
4509 (write_register): Convert byte order on the way out.
4511 * exec.c (file_command): Add.
4512 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4513 (xfer_memory): Common function between core_xfer_memory and
4515 (exec_xfer_memory): Use it.
4517 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4519 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4520 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4521 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4523 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4525 Merge Intel 960 port of gdb, continuing...
4527 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4528 symbol_file_command): Pass from_tty arg to hush 'em up.
4530 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4531 Add magic numbers for 960 COFF format.
4533 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4535 Merge Intel 960 port of gdb, from Intel "1.2" release.
4537 CHANGE_LOG entries from their port, which was based on
4540 Thu Sep 6 11:02:22 PDT 1990
4541 Remove temp file if download is interrupted.
4543 Wed Aug 1 09:08:33 PDT 1990
4544 Now uses binary protocol to talk to NINDY.
4545 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
4546 Times out after 5 seconds when trying to talk to NINDY.
4548 Tue May 29 12:54:49 PDT 1990
4549 Added variable baud rate (-b switch).
4550 Source code reorganization.
4552 Thu Apr 26 11:09:55 PDT 1990
4553 More cleanup of batch mode; specifically, execute "-s", "-e", and
4554 "-se" switches as soon as they are encountered on the invocation line.
4556 Fri Apr 20 13:47:15 PDT 1990
4559 Thu Apr 19 09:54:28 PDT 1990
4560 Add 'reset' command.
4562 Wed Apr 18 09:48:07 PDT 1990
4563 After opening remote tty, wait for 1 second to go by without input
4564 from it before trying to talk to NINDY (fixes problems with the
4565 Heurikon HK80/V960E).
4567 Mon Apr 4 16:33:05 PDT 1990
4568 Some output was not being suppressed in 'batch' mode.
4570 Thu Mar 22 15:31:11 PST 1990
4571 Ask user if old symbol table should be deleted when new file is
4574 Allow user to run a program downloaded before gdb960 was brought up.
4576 Correct "exec-file" help message for i80960 context.
4578 Correct bug in calculating user space address: could occasionally
4579 corrupt user program.
4581 Make sure to zero low-order bits in rip's because of bug in 960CA
4582 A-step part: could cause operation faults when "next"ing across
4585 Correct bug that made it impossible to get source line numbers for
4586 code loaded at addresses higher than 0x7fffffff.
4588 Wed Jan 10 12:43:22 PST 1990
4589 Open remote tty for exclusive use.
4591 Fri Jan 5 12:14:42 PST 1990
4592 Correct disassembly (CA manual was right after all):
4593 opcode for sysctl is 0x659
4595 Mon Oct 23 12:03:04 PDT 1989
4596 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4598 Mon Oct 16 14:15:09 PDT 1989
4599 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4601 Mon Oct 2 15:56:31 PDT 1989
4603 Added 960CA disassembly support.
4605 To simplify maintenance:
4606 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4608 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4609 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4610 - made disassembly interface identical to that in gdmp960.
4614 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4616 * target.h: Allow targets to stack. Add target_has_memory,
4617 _registers, etc. Restructure memory access and "info files"
4618 to walk the target stack.
4619 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4620 target.c: Change tables to match target.h.
4621 * inflow.c (child_mourn_inferior): pop child_ops.
4622 (generic_mourn_inferior): Use new has_stack flag.
4623 * infptrace.c (child_xfer_memory): New memory regime.
4624 * inftarg.c (child_files_info): New "info files" regime.
4625 * remote-eb.c: New memory regime, new info files.
4626 * remote-vx.c: New memory regime, new info files. Now use
4627 separate targets for VxWorks attachment to machine, and
4628 actually running a process under VxWorks, since one has
4629 stack & execution & regs and the other doesn't.
4630 * remote.c: New memory regime, new info files.
4631 * sparc-xdep.c (fetch_core-registers): New memory regime.
4632 * target.c: New routines and support for stacked targets,
4633 new memory regime, new info files regime.
4636 Generalize section handling for an arbitrary number of sections,
4637 including use of the new BFD (binary file) library.
4638 * gdbcore.h: Add struct section_table.
4639 * exec.c (build_section_table): Iterate all sections and
4640 record what gdb needs to know about them.
4641 (exec_command): Use it.
4642 (exec_xfer_memory): Use the table.
4643 (exec_files_info): Print the table.
4644 * core.c (core_file_command, core_xfer_memory, core_files_info):
4646 * source.c (find_source_lines): Use bfd_get_mtime.
4647 * dbxread.c: Quick changes to make it compile with new BFD.
4648 * utils.c (error): Avoid using bfd_error in generic routines.
4650 * core.c (core_fetch_registers): Get from the ".regs" section of
4652 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4654 * inferior.h (attach_flag): Export.
4655 * infcmd.c (run_command): use new target_create_inferior.
4656 * infrun.c (child_create_inferior): Don't return result.
4657 * Makefile.dist (VERSION): 3.91.4.
4659 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
4661 * breakpoint.c (bpstat_num): Handle breakpoints which have
4662 since been deleted, such as temporary breakpoints.
4663 infcmd.c (program_info): ditto.
4665 * core.c (core_file_command): Display the frame where the core
4670 * remote-vx.c (target_command): Merge in target command from
4671 targ-vx.c. A few other cleanups.
4673 * TODO, Projects: Lots more stuff to do...
4675 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4677 Massive changes to wall off the remote-debugging interface
4678 behind a function vector. The port to handle VxWorks targets
4679 is also part of this.
4681 All files: Replace references to renamed functions,
4682 remove references to remote_debugging, remove references to
4683 have_include_file, have_core_file in favor of target_has_stack,
4684 target_has_memory, etc.
4686 * Modularize the breakpoint interface.
4687 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4688 a breakpoint instruction.
4689 breakpoint.c: struct breakpoint's shadow_contents now sized as
4691 (insert_breakpoints): Vector to target to install breakpoints.
4692 (remove_breakpoints): Vector to target here too.
4693 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4694 sparc-tdep.c (single_step): Use new breakpoint interface for
4695 the single-step breakpoints.
4696 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4697 New file, contains routines to insert and remove breakpoints by
4698 reading out the old contents and later replacing them. This is
4699 how ptrace breakpoints work, and many remote systems as well.
4701 * tm-vxworks68.h: New config file, overrides a few things for
4702 Wind River's preferences.
4704 * target.h: New file, for transfer vector used to talk to the
4705 inferior (child, attached, core, exec, remote, etc). All accesses
4706 to the thing being debugged should come through these vectors.
4707 target.c: New file, routines to handle transfer vector.
4708 (various files): Add transfer vectors XXX_ops for the various
4709 targets and pseudo-targets (core files, etc) we support.
4711 * breakpoint.c (bpstat_stop_status): Further explorations of
4712 watchpoints and why things don't work all the time.
4713 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4715 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4716 the local gdbinit if it doesn't already have it.
4718 * core.c (core_ops): add and install.
4719 Allow core debugging without exec file.
4721 * dbxread.c (free_and_init_header_files): Merge two fns.
4722 (end_symtab): Free named symbol table when a new version comes in.
4723 (read_dbx_symtab): Relocate all kinds of symbols with base
4724 address. First step toward handling different text, data, bss
4726 (add_file_addr_command): Renamed add_file_command.
4727 (add_file_command): Vector to remote handler.
4728 Add "load" as an alias for "add-file" command.
4730 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4731 non-returning functions.
4733 * exec.c: Add exec_ops, and push it as a target when an exec
4736 * infcmd.c (run_command): Pass executable file name and arg list
4737 separately when starting an inferior. Permit "run" when no exec
4738 file is specified, for VxWorks.
4739 (detach_command): Move to child_detach in inftarg.c.
4741 * inftarg.c: New file. Unix-child-specific routines, and the
4742 child_ops structure.
4744 * inferior.h (registers): Export "registers" as the way for
4745 target dependent register handlers to find gdb's local copy of
4746 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4747 since it is now used by places that want wait_for_inferior to
4748 handle the grunge but want to see every trap from the inferior.
4750 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4751 Eliminate remote_debugging hooks in terminal handling.
4753 * infrun.c: Replace start_inferior with child_create_inferior.
4754 Move all the hair of Unix shells and ptrace idiosyncracies into
4755 child_create_inferior, so remote handlers don't have to deal.
4756 Remove running_in_shell. Rename stop_after_attach to
4757 stop_soon_quietly, and use it in a few other places where we want
4758 to just call wait_for_inferior and get control back on the first
4759 trap. trap_expected now never takes a value > 1.
4760 (init_wait_for_inferior): Initialize static vars when a new
4763 main.c (gdbinit): Add new hook for .gdbinit file name, let
4764 it be overridden by config files as GDBINIT_FILENAME.
4765 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4766 Both of these are used for VxWorks gdb.
4768 mcheck.c: rename include file "gmalloc.c" to avoid problems
4769 with system include file "malloc.c".
4771 param-no-tm.h: New include file, same as param.h but does not
4772 include the default "tm.h" file. This is used in files where
4773 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4775 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4777 remote-vx.c: New file, VxWorks remote debugging support. Uses
4778 RPC routines that are shared with the target system, in directory
4781 remote.c: Vectorize remote interface.
4783 source.c: Globalize source_path, and make an alias "l" for "list"
4784 since we now have the "load" command.
4786 sparc-xdep.c: Use new param-no-tm.h.
4788 symmisc.c (free_named_symtab): Add new function from Wind River.
4789 However, ifdef it out for now while we think about what it should
4792 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4794 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4795 non-Unix-children handle this with their own code in the target
4798 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4799 source and target lists. Add vx-share to default list of include
4800 directories. Add new files to src and target lists: mem-break,
4801 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4802 ${srcdir} versions of munch and createtags are used.
4804 * valops.c (find_function_addr): Split out of call_function.
4805 (call_function_by_hand): Rename call_function; this function
4806 calls functions in the target by laboriously patching the target
4807 word-by-word with the right stack, args, regs, etc.
4810 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
4812 Handle AMD 29000 a bit better.
4814 * remote-eb.c (readchar): Mask received char log to make it readable.
4815 (remote_start): Pass arguments down to executing program.
4816 Make startaddr unsigned.
4817 infrun.c (start_inferior): Accept args, pass them to
4819 infcmd.c (run_command): Pass args down to start_inferior.
4821 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
4822 the target object file format.
4823 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
4825 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
4826 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
4828 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
4830 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
4831 * TODO: We did a few things, we have more to do though.
4833 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
4834 * inflow.c (inferior_died): Clear deferred stores.
4836 * Debug problems with dummy frames and calls to the inferior.
4837 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
4838 * sparc-tdep.c (do_restore_insn): Simplify.
4839 (sparc_frame_find_saved_regs): Simplify and fix what we find.
4840 (sparc_push_dummy_frame): Simplify and fix what we push.
4841 (sparc_pop_frame): Slightly more hair here, deciding whether
4842 we are restoring a saved PC or returning to a return address in %i7.
4843 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
4845 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
4846 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
4847 * obstack.h (chunkfun): ditto.
4848 * defs.h (xmalloc, xrealloc): ditto
4850 * utils.c (quit): Grab the terminal from the child if necessary.
4852 * inflow.c (term_status_command): Rename to term_info, change
4855 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
4856 (is_delayed_branch): Speed up.
4857 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
4858 Still missing some float ops, and needs testing.
4860 * Support for input and output radixes other than base 10
4861 * defs.h (input_radix, output_radix): Declare.
4862 * expread.y (yyparse, parse_number): Handle changes of input
4863 radix, and ambiguous names-or-numbers in radixes >10.
4864 * printcmd.c (print_scalar_formatted): Print formatted hex
4865 numbers in varying column widths.
4866 * valprint.c (val_print): Use output_format to print scalar ints.
4867 (set_input_radix, set_output_radix, set_radix): Create.
4868 (set_output_radix): Set output_format from output_radix.
4869 (_initialize_valprint): add `set radix' but leave the others off.
4871 * main.c (execute_command): Let stupid questions be turned off.
4872 (_initialize_main): Handle "set stupidity", etc.
4874 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
4875 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
4877 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
4879 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
4880 bfd stuff is still screwed up, but with some manual work, it
4883 * breakpoint.c (bpstat_do_actions): Start over if a command
4884 proceeds the inferior, since the inferior will have stopped and
4885 will need to have its new stop-actions taken care of.
4887 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
4888 compiler fits, simplify it.
4890 * gdb.texinfo (directory command): Doc new dir command.
4891 source.c (directory_command): "dir" now puts things on the front
4892 of the path, moves dups up front, and handles multiple names
4893 on the command line, inserting each one in order. It also
4894 blows away cached line and full_filename info.
4896 * stack.c (backtrace_command): Skip "more stack frames follow"
4899 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
4900 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
4901 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
4902 The only odd one was Gould NP1, which had defined vprintf to
4905 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
4906 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
4907 variable, inspect_it.
4908 valprint.c (print_string, val_print): Use the global inspect_it
4909 to indicate whether to print in Epoch style or normal style.
4911 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
4913 * printcmd.c (call_command): add an alias for the "print" command
4914 which runs expressions and doesn't print the result if void.
4915 (print_command_1): implement it.
4917 * command.c: Remove #if 0'd code. Initialize all the fields
4918 in add_cmd (). Rename do_nothing_command to
4919 not_just_help_class_command, and make it externally visible.
4920 command.h: add user_commands to struct.
4921 * main.c (define_command): Don't overload c->function with a char
4922 string as well as a function pointer.
4924 * eval.c (evaluate_subexp): Reinstall tiemann changes to
4925 calling convention of value_struct_elt () that got dropped in
4928 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
4929 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
4931 * tm-sparc.h (POP_FRAME): replace some constants with defines.
4933 * sparc-xdep.c (store_inferior_registers): defer stores to regs
4934 until a good time (e.g. when we are about to run the child),
4935 saving ptrace calls.
4936 * infrun.c (proceed): handle DO_DEFERRED_STORES.
4937 * tm-sparc.h: define DO_DEFERRED_STORES.
4939 * sparc-xdep.c (store_inferior_registers): when storing float
4940 registers, don't store stack regs too. When storing the SP,
4941 however, DO store the stack regs too. This fixes a bug in which
4942 the dummy frame is not recognized when a call_function finishes,
4943 because its frame pointer (in the stack regs) was never
4945 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
4946 even though we don't know how to read them from an inferior.
4947 valops.c (call_function): Comment about storing SP.
4949 * infrun.c (save_inferior_status): Save away the original bpstat
4950 chain so it can be restored later. Install the copied version for
4951 use by whoever saved the status. It will be blow away by
4952 restore_inferior_status, and the original chain restored. This is
4953 important for people who have pointers into the original.
4955 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
4956 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
4957 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
4960 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
4962 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
4963 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
4964 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
4966 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
4968 * Merge Mike Tiemann's multiple inheritance changes from Sun.
4969 Store the baseclasses in a type struct starting from array element
4970 0 rather than from the unusual array element 1.
4972 dbxread.c: the above.
4973 (virtual_context): Add
4974 Read new debug information about which virtual function table
4975 a virtual function is from, and store it in fn_field.fcontext.
4977 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
4978 TYPE_FN_FIELD_STATIC_P.
4980 symtab.c: the above.
4981 valops.c: the above. Handle pointer casts of object *'s.
4982 (search_struct_method): Add.
4983 (value_struct_elt): First arg is now a pointer to a value, and is
4986 valprint.c: the above.
4987 values.c (value_virtual_fn_field): Add type arg. Handle
4988 offsetting to the proper object when calling virtual fns.
4990 (baseclass_addr): Add valuep arg.
4992 * README: Document the current state of BFD config (missing).
4993 * TODO, ChangeLog, Makefile.dist: Roll version.
4994 * WHATS.NEW: Add summary of changes since 3.5.
4996 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
4998 * dbxread.c (read_struct_type): Clear bit vectors whenever
5000 symtab.c (B_CLRALL): define.
5002 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5003 using == rather than =. Huh... This fixes the dreaded problem
5004 wherein builtin_type_int becomes TYPE_CODE_FLT.
5006 * core.c (info_files): Show the inferior pid.
5008 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5009 already knows how to look in the source directory.
5011 * Remove psymtab hair from many places. Remove duplicated code
5012 for searching symbol tables. Hide psymtabs from most places.
5013 Make it fast to get from a psymtab to its symtab.
5015 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5016 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5017 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5018 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5019 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5020 new symtab completely. New psymtabs get symtab pointer
5021 initialized to zero. Remove MI warning printf.
5022 symtab.h: Comments. Add psymtab to symtab pointer.
5023 (PSYMTAB_TO_SYMTAB): New macro.
5024 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5025 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5027 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5029 (print_frame_info): Avoid special-casing symbols that have not yet
5032 * source.c (open_source_file): Quick path if we have already
5033 located the source file by its full name.
5035 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5036 find_pc_psymtab. When a name is found in the misc function
5037 vector, search the symbol table for its mangled name, not the
5038 name that the user typed.
5040 * bfd.h: Fix missing comment terminators, make #endifs match.
5042 * valarith.c (value_less): Handle unsigned int comparisons.
5043 Add FIXME about pointer compares, which assume host and target
5044 pointers are the same.
5046 * command.c (do_nothing_command): lint
5047 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5048 fix comments on debug symbol format for visibility. Actually set
5049 visibility of symbols.
5050 main.c (echo_command): lint; use <readline/history.h>.
5051 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5052 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5053 pointing past end of allocated memory; saber complains.
5054 obstack.h: Declare the external functions that we use.
5055 valarith.h: use <string.h>
5056 solib.c (solib_add): lint.
5058 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5060 * main.c (initialize_main): Default info_verbose to off, now that
5061 symbol reading is fast.
5062 (quit_command): Avoid clobbering exec_bfd while quitting.
5064 * Initial BFD (binary file diddling library) merger:
5065 coffread.c: Change AOUTHDR to struct exe_hdr.
5067 core.c: initialize initialized data at compile time.
5068 (core_file_command): Move from coredep.c, convert to bfd.
5069 (xfer_core_file): Convert to bfd.
5070 exec.c (exec_file_command): use bfd routines.
5072 mips-tdep.c: Remove exec_file_command and friends.
5075 * coredep.c: (fetch_core_registers) Convert core_file_command to
5076 fetch_core_registers.
5077 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5079 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5080 (my_bfd_read): More bogosity, which I don't think we call.
5081 (program_name): Remove this atrocity asap!
5083 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5086 values.c: allocate_repeat_value was not clearing the
5087 optimized_out field.
5088 (value_static_field): minor stylistic fix (wrong macro was used).
5089 valops.c (value_struct_elt_for_address): didn't work for C++
5092 * signame.c (_initialize_signame): Initialize signal names once.
5094 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5095 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5096 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5098 * remote-eb.c: Support user-settable baud rates on the serial port.
5100 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5102 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5104 * tconfig/sun3os4: Remove warning about native assembler,
5105 since it also occurs in the xconfig file.
5107 * findvar.c (registers): Allocate some slop after `registers'
5108 to prevent stray accesses from trashing the next variable.
5110 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5111 on the sun-3, by changing the #ifdef from `sun3' (which is not
5112 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5113 vars, which happened to follow `registers' in the executable.
5115 * readline/history.c (history_search): Heed gcc-2's advice
5116 and parenthesize && inside ||).
5118 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5119 tm-29k.c: Insert FSF copyright headers.
5121 * remote-eb.c: Better comments.
5123 * Makefile.dist: Update to 3.91.6.
5124 * TODO: note PREPARE_TO_STORE problem.
5126 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5128 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5130 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5132 * infrun.c (wait_for_inferior, at end): Don't set up
5133 prev_* if the inferior no longer exists.
5135 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5136 CANNOT_EXECUTE_STACK.
5137 valops.c (call_function): Use it.
5139 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5141 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5142 infrun.c (wait_for_inferior, 2 places): Use it.
5144 * values.c (value_being_returned): Only use
5145 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5147 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5148 right thing for remote-eb.c.
5150 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5151 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5153 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5154 (FRAME_FIND_SAVED_REGS).
5156 * findvar.c ({fetch,store}_registers): Check for
5157 REMOTE_{FETCH_STORE}_REGISTER macro.
5159 * findvar.c (get_saved_register): Add argument lval and
5160 change meaning of argument addr.
5161 findvar.c: Change calls to get_saved_register to reflect
5162 new calling convention.
5163 valops.c (value_assign): Use get_saved_register instead of
5164 find_saved_register.
5166 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5168 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5169 an (uninitialized) pointer to one. Use "&" when passing it
5172 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5174 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5177 * coffread.c (symbol_file_command): Put semicolon after
5179 Put safe_to_init_tdesc_context in #if defined (TDESC).
5180 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5181 coffread.c: #include <sys/stat.h>.
5182 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5183 Add missing ')' in check for "lc%" and friends. Remove
5185 Declare read_one_sym() at top of file.
5186 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5187 MC68WRMAGIC can have the same value without causing a duplicate
5190 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5192 * Allow a Makefile to be built without building the
5193 tm and xm file links that screw up builds in subdirectories.
5194 This is done with `config.gdb none', then you can do things
5195 like `make gdb.tar.Z'.
5196 * tconfig/none: Config file for no target system
5197 * xconfig/none: Config file for no host system
5198 * config.gdb: If no TM or XM files are called out by the
5199 host or target file, don't make links for them.
5201 * cplus-dem.c: Add documentation.
5203 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5204 simple error, so the user's gdb doesn't crash due to some object
5205 file problem (e.g. somebody is rebuilding the file out from under
5208 * printcmd.c (print_address_symbolic): demangle the symbol.
5210 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5211 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5212 (alldeps.mak): sort and uniq all results from this; duplicates
5213 hose gdb.tar.Z link building. Remove RCS files from
5214 tconfig and xconfig. Add config files for sun386. Add
5215 a few odd files to OTHERS and HFILES.
5217 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5219 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5220 Roll version number to 3.91.5. Make lint work in bindir.
5222 * README: Document cross-debugging and new file structure.
5224 * blockframe.c: Lint. Include "value.h" to declare read_register.
5225 (find_pc_partial_function): remove duplicate line.
5227 * command.h: Lint. Declare error_no_arg and dont_repeat.
5229 * tm-news.h: Remove inadvertently duplicated stuff.
5231 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5232 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5234 * config.gdb: Allow `config.gdb host target' form. Clean
5235 up previous change that printed bogus messages when you just said
5238 * core.c: #include "command.h" for lint.
5241 * main.c: Remove some casts of enums. Lint.
5248 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5250 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5251 read it from memory. This will allow us to save ptrace calls
5252 eventually. Changed caller single_step too.
5254 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5255 that we aren't going to use, saving many ptrace calls, especially
5256 when watchpointing or single stepping. Use some #define's for
5258 (store_inferior_registers): Ditto.
5259 (core_file_command): Use some #define's for constants.
5261 * tm-sparc.h: Add #define's for some register numbers, so we
5262 can eliminate the use of random constants in sparc-xdep.c.
5264 * stack.c (frame_command, print_frame_info, up_command,
5265 down_command) Remove frame_changed, since it
5266 causes a bug and doesn't seem to do anything useful. In some
5267 places it was used as a flag, in others as a stack level (?).
5269 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5270 default is to use the portable (vprintf) version rather than the
5272 * xm-news.h (MISSING_VPRINTF): Add.
5274 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5276 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5278 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5279 about linking debugged programs -Bstatic in the sun?os4 config
5280 files in tconfig and xconfig subdirectories.
5282 * main.c (main): Remove unreached exit(0) now that we exit
5285 * Create TODO file for online bug list. There are too many
5286 "little" bugs to keep track of on paper.
5288 * Change Projects file to refer to bug-gdb@cygnus.com
5289 rather than kingdon@ai.
5291 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5293 * Makefile.dist (VERSION): 3.91.4 now.
5295 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5296 (condense_misc_bunches): Add sanity check that misc_count is
5297 the same as the number of symbols in the bunch.
5299 * coffread.c: rename init_misc_bunches. Pass an argument
5300 to condense_misc_bunches (a zero).
5302 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5303 every time we are called; don't rely on our caller to do it.
5304 (add_file): Remove call to init_misc_bunches.
5306 * mipsread.c: Only warn, don't error, if unknown symbol types.
5307 This keeps an old gdb from falling on its face if it sees newly
5308 extended symbol info. Rename init_misc_bunches.
5310 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5312 * Merge in changes from Per Bothner for DECstations and other
5313 MIPS stuff. The rest is Bothner speaking:
5315 The next message is a merger of Alessando Forin's mips port with
5316 mine. I've tried to use my good if biased judgment to get
5317 the best of both. It *does* need testing.
5319 Some of the changes are general, *not* mips-specific.
5322 Didn't believe in little-endian bit order.
5323 There are still inconsistencies about whether flags
5324 like BITS_BIG_ENDIAN are integer (#if ...) or
5325 boolean (#ifdef ...). I tried to paper over them.
5327 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5328 Moved some misc_function code that was common to
5329 {dbx,coff,mips}read.c to symtab.c.
5330 In the process, I think I cleaned things up a bit.
5331 At the same time, moved obsavestring and obconcat to symtab.c.
5334 Removed obsolete condense_addl_misc_bunches (use
5335 condense_misc_bunches(1) instead).
5338 Needed to include <sys/dir>, at least on DECstations.
5340 valops.c, mips-tdep.c, tm-mips.h:
5341 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5342 conventions (when STACK_ALIGN is insufficient).
5343 Needed on mips, where doubles need 8-byte alignment,
5344 but ints only need 4.
5347 Removed cruft that was not being used.
5348 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5351 Print $ before register-names (I think that makes things a little
5353 Never print two instructions, even if one delays.
5354 Removed hex-disassemble set_cmd. (This is not mips-specific,
5355 so I think the argument is whether it is generally worthwhile or not.
5356 I'm inclined to think not, given how easy it is to
5357 convert between radixes in gdb.)
5360 This is basically Alessando's code.
5361 It doesn't use obstacks; I changed it to use obstacks
5362 in a few minor places where using malloc causes a
5363 memory leak. (Probably, more places could/should be changed.)
5364 I added record_misc_function where it was missing.
5365 In symbol_file_command and add_file_command, I tried
5366 to make the code consistent with more recent versions.
5367 Minor sylistic changes in parse_procedure.
5368 Make a .gdbinfo. psuedo-symbol point back to the real
5369 procedure symbol (using the isym field).
5372 This is basically from my port, but with a lot of details
5373 and a number of routines merged in from Alessando's version.
5374 I basically used my code "raw" backtrace (use heuristics
5375 from the actual code, rather than symbol table info) - though
5376 the idea is Alessandro's. I feel my code is a little cleaner
5377 here, particularly in being a little more flexible, such as being
5378 able to handle gcc-produced code (which it now can).
5379 It also doesn't do frame caching (which is not useful
5380 more recent gdb versions).
5381 I also used my code for push_/pop_dummy, more or less.
5382 I tried to incorporate AF's code for testing sigtramp
5383 while backtracing; I probably got it wrong.
5384 Added mips_print_register, which tries to scrunch as much
5385 information as possible on a screen...
5386 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5387 under mips-pinsn.c), I don't see anything mips-specific here,
5388 and I don't see it being all that useful anyway.
5391 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5392 Use more register names (rather than hard-cases numbers).
5394 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5396 * Hack up 3.90.11 changes:
5398 * Makefile.dist (depend): parameterize $(GCC).
5399 Add solib.c and solib.o.
5400 (readline): Fix vpath for both absolute or relative SRCDIR.
5402 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5403 Also, let the part I didn't understand at least compile so
5404 I can test the rest. FIXME.
5406 * dbxread.c: Fix thinko using strcmp.
5407 (init_psymbol_list): declare static.
5408 (partial_symbol_file_open): Comment cleanups better, avoid
5409 cleaning up the string table since the caller will do that.
5410 Move the stat for mod time into symbol_file_command, temporarily.
5411 (There should be a mod time for each symbol file, eventually,
5412 to control its rereading. FIXME.)
5414 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5415 SunOS, which gives error for shared libs otherwise. (From
5416 Schaefer, probably FIXME needs work for portability.)
5418 * solib.c: Move #include "param.h" to work.
5419 Lowercase all the Uppercase Letters In the Messages.
5420 (find_solib): Clean up inferior_so_name for debug printouts.
5421 Allow no argument, to mean all shared libraries.
5423 * symmisc.c: include param.h to get CLEAR_SOLIB.
5425 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)

5436 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5440 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5442 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)

5449 Put parens around gcc_p in expansion.
5451 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5453 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5455 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5457 * Changes for Sun shared libraries:
5458 blockframe.c (find_pc_partial_function): If a non-text symbol
5459 is found, set *address = pc - FUNCTION_START_OFFSET.
5460 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5461 Disable breakpoints instead of giving an error.
5462 source.c (select_source_symtab): Initialize cs_pst.
5463 symmisc.c: Call CLEAR_SOLIB if defined.
5464 symtab.h: Make text{low,high} CORE_ADDR not int.
5465 (psymtab): New field addr.
5467 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5468 (record_misc_function): Give correct type for N_DATA symbols.
5469 (condense_misc_bunches): do "misc_function_count = j" regardless
5471 Take code which is shared between symbol_file_command and
5472 add_file_command and put it into partial_symbol_file_{open,read}.
5473 Split add_file_command into add_file_command and add_file.
5474 Make psymtab_to_symtab read in the string table if the file
5476 Two new parameters to read_dbx_symtab and start_psymtab.
5477 tm-sunos.h: New file.
5479 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5481 * infcmd.c: Change cont_command to continue_command and "cont"
5484 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5486 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5488 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5490 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5491 size 1,2,4,8 rather than size < 8.
5493 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5494 as necessary, not just once.
5496 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5498 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5500 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5502 * tm-news.h: Add CALL_DUMMY_*.
5504 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5506 * config.gdb: In list_host, list_target, use ${i}, not $i.
5508 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5510 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5512 * sparc-opcode.h: Change all store floating-point state register
5513 instructions to have the right match & lose fields.
5515 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5517 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5519 config.gdb: If srcdir != ., create readline directory and
5520 copy a makefile into it.
5522 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5523 consistency with POSIX.
5525 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5526 when we exit its exp_valid_block.
5528 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5530 * Makefile.dist: Bump version to 3.91.3.
5532 * Clean up handling of breakpoint commands (somewhat).
5533 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5535 inferior.h: Add breakpoint_proceeded to inferior status struct
5536 and globals; save it and restore it.
5537 (clear_breakpoint_commands): Cleanup, remove old #define.
5539 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5540 (save_inferior_status, restore_inferior_status): handle it also.
5541 (proceed): Remove earlier code that set breakpoint_proceeded.
5542 It is now set only in clear_proceed_status.
5543 (clear_proceed_status): Cleanup, use bpstat_clear rather
5544 than clear_breakpoint_commands. No callers need the stop_bpstat
5545 between clear_proceed_status and proceed.
5547 infcmd.c: Add breakpoint_proceeded definition and comment.
5548 (cont_command, jump_command, signal_command): Move call to
5549 clear_proceed_status right next to call to proceed.
5551 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5552 caller's argument while running down the chain of breakpoints.
5553 Use new variable "breakpoint_proceeded" to determine when
5554 a command that it executes moves the inferior past the
5556 (bpstat_clear): Handle NULL argument.
5557 (bpstat_clear_actions): Avoid useless call to
5558 breakpoint_auto_delete.
5559 (delete_breakpoint): Clean up bpstat's that are pointing to
5560 the deleted breakpoint from the stop_bpstat chain.
5561 (breakpoint_auto_delete): Simplify.
5563 * Clean up handling of EOF, error on stdin, etc. This was
5564 prompted by a network problem that caused gdb to go into an
5565 infinite loop filling up its malloc'd memory.
5567 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5568 not clear_breakpoints_commands, which is now gone.
5569 (main): If command_loop returns (e.g. from EOF on stdin), do
5570 a quit_command (looping back to command_loop if quit_command
5571 doesn't really quit).
5572 (command_loop): check result from command_line_input and
5573 exit if it returns NULL, rather than passing the NULL to
5575 (gdb_readline): Free malloc'd result space before returning
5578 * utils.c (query): Handle C-d to mean "yes", just as if the
5579 input was not a terminal. Also avoid infinite loop if EOF
5580 occurs in mid-input-line before newline. This allows
5581 query to be used at EOF on stdin with reasonable results.
5583 * infrun.c (proceed): Set breakpoint_proceeded.
5585 * values.c (value_as_long): Avoid infinite recursion for enums.
5586 (_initialize_values): Fix typo in help msg (kingdon).
5588 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5589 RL_LIB for linking. This allows -lreadline for linking
5590 and nothing for dependencies, once readline is a real library.
5592 * config.gdb: Jim Kingdon: give useful error message if the
5593 host or target type is not recognized.
5595 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5596 it just defines it. Dumb, but deal with it.
5598 * Jim Kingdon suggests:
5599 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5601 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5603 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5605 * Clean up Bothner's changes.
5607 * blockframe.c (clear_pc_function_cache): New function.
5608 * blockframe.c: remake cache_pc_function_* static.
5609 * dbxread.c (symbol_file_command): remove references to
5610 cache_pc_function_* variables.
5611 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5612 * printcmd.c: Avoid kludging a global variable (addressprint)
5613 to avoid printing the address of a string twice. Instead,
5614 pass the format letter 's' down low enough that it can be seen
5615 to avoid this problem.
5616 (print_formatted): Pass format arg to value_print.
5617 (restore_addressprint): Remove function.
5618 (do_examine): Avoid hacking addressprint, cleanups and such.
5619 (print_frame_args): Add a comment to a Bothner change.
5620 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5621 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5622 to wipe out the values cached in blockframe.c.
5623 * symtab.c (find_method): Add comment saying how big you must
5624 allocate to be "big enough". Per being terse again.
5625 * valprint.c (val_print): Handle format letter "s" to print
5626 strings without addresses. Add comment to vtbl printing code
5627 which casts with wild abandon. Rearrange reference-printing
5629 @0xaddr: value (print w/addressprint)
5630 value (print w/~addressprint)
5631 @0xaddr (parameter lists w/addressprint)
5632 or nothing (parameter lists w/o addressprint)
5634 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5636 * Merge more changes from Per Bothner:
5638 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5639 annoying) that I tried to improve it. Here are my suggestions.
5641 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5644 Do automatic de-reference when taking the address of a reference.
5646 Don't deref_ref when printing parameter lists.
5648 More attempts at treating refernences properly.
5650 In val_print, if deref_ref==0, don't print dangling " = ".
5652 Add COERCE_REF macro, which de-references an REF.
5654 * Merge changes from Per Bothner:
5656 * Fixed (Sony news)-specific configuration problems.
5657 * Fixed other problems with using vanilla pcc and libc (enum problems;
5658 assumption that vsprintf exists).
5659 * Some major speed-ups (finc_pc_partial_function now caches a match;
5660 parsing avoids duplicate symbol_lookup calls).
5661 * Changed handling of baseclasses (no longer use baseclasses field
5662 of struct type, use the first n_baseclasses fields instead).
5663 * Various minor changes/fixes, most C++-related.
5666 Cache the most previous match from find_pc_partial_function.
5667 (Save both low and high ends of matching function's pc range.)
5668 This speeds up the loop of infrun.c:wait_for_inferior quite
5669 a bit, and makes step/next commands much zippier.
5671 Added an enum->int cast (otherwise, some compilers barf).
5673 No longer set baseclass offset to 0, since multiple
5674 inheritance now mostly works.
5675 Added a number of casts, to shut up compiler warnings
5676 (after stabs where made enums, not ints).
5677 When discarding a symbol table (in symbol_file_command),
5678 must clear the cache introduced in blockframe.c.
5679 Don't convert $vtbl_ptr_type to vtbl any more.
5680 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5681 Mask off sign bit emitted by g++ for virtual table offset.
5682 Set voffset to -1 (not 1) for static member functions.
5684 Changed parsing/lexing of names to avoid doing symbol lookup twice
5685 (once when lexing to determine symbol class, once for real).
5686 Now only call symbol_lookup once. Fields of 'this' win especially big.
5688 Subpress printing addr twice in the case of 'x/s addr'.
5690 lookup_basetype_type is no longer used.
5691 Add find_methods as recursive helper function to decode_line_1.
5692 This allows multiple inheritance to work.
5693 Also, once one or more matches has been found, do not look in
5694 base-classes. (Baseclass methods would be overridden, anyway.)
5696 Removed baseclasses array in struct type.
5697 Instead of using baseclasses[i], use fields[i-1].
5698 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5699 Changed sign convention of voffset (previous was inconsistent).
5701 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5703 Used to assume existence of vsprintf. Re-written to not need it
5704 if HAVE_VPRINTF is undefined.
5706 typecmp was too pessimistic. Made it less so.
5708 Don't print space after address.
5709 If vtable points to a misc symbol (with 0 offset), print it,
5710 since that indicates the actual class of the object.
5711 Changed ype_print_derivation_info to use new inheritance
5712 scheme (without baseclasses vector).
5714 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5715 Also, changes needed because TYPE_BASECLASSES were removed.
5717 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5719 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5722 If there is no path set, and the symbols don't indicate what directory
5723 a file was compiled in, look in the current directory. But either
5724 a path or a known compilation directory will prevent this.
5727 Three independent bug fixes:
5728 * Remove the #if 0 block that breaks some stuff.
5729 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5730 adapt gdb to either SunOS 4.0.* or 4.1.
5731 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5734 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5737 (type_print) Demangle the name being printed.
5738 (type_print_base) Handle botched demangling without coredump (tiemann).
5741 (check_stub_method): Document routine.
5742 (tiemann) fix bug for no-arg functions
5743 Avoid clobbering beyond end of malloc'd storage.
5744 Terminate the argument list properly.
5746 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5748 * Changes merged by John Gilmore:
5751 In breakpoint_1, use new print_address_symbolic instead
5752 of find_pc_partial_function. (This forces use of assembler-level
5753 addresses, and avoids misleading non-mangled source-level names.)
5755 Generalize ansi argument such that -1 means skip arglist totally.
5756 Removed global variable print_ansi_qualifiers (which made
5757 code non-reentrant), in favor of extra explicit arguments
5758 to internal routines.
5760 Add new helper function print_address_symbolic.
5761 Use find_pc_misc_function instead of find_pc_partial_function
5762 (since we want assembler-level symbols here).
5764 Print unknown function as just "f (...)", not "f (...) (...)".
5765 Use new fputs_demangled explicitly.
5767 Fixed a typing violation (problem: value.h cannot be imported
5768 without renaming many variable in this file).
5769 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5770 decode_line_1: Moved forward some never-reached code.
5771 Made decode_line_2 skip function prologues correctly.
5773 fputs_filtered should not demangle by default.
5774 Add new fputs_demangled to demangle on demand..
5776 Change value_struct_elt to use value_primitive_field (using recursive
5777 utility function search_struct_field). This allows foo.bar to work
5778 for multiple inheritance (so far only for data fields).
5779 Change check_field in the same way (recursive helper function
5780 to support multiple inheritance).
5781 (Note: there are more of these problems that I haven't fixed.
5782 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5783 value_of_this: 'this' symbol name is now just "this", note "$this".
5785 Don't print static members.
5786 Avoid printing "members of <type>" if there are none.
5787 Simplified type_print_derivation_info by merging duplicate code.
5788 Remove useless blank lines in type_print_base (ptype command).
5790 Added declaration of new routine value_primitive_field.
5792 Added value_primitive_field which is generalized version of
5793 value_field that can handle multiple inheritance (non-zero offsets etc).
5794 Re-implemented value_field to call value_primitive_field.
5796 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
5798 * infcmd.c -- insert else to avoid 'delete env' coredump when you
5799 delete the whole environment. Karl Berry reported the bug.
5800 * source.c - fix openp to avoid //'s in filenames, which
5801 trigger an Emacs bug causing it to not be able to find files
5802 when running gdb in a window.
5803 * dbxread.c - zap the #if 0 that botches the add-file code.
5804 It seems to work a lot better without all the code commented out.
5806 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
5808 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
5811 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
5813 * Makefile - added a ${CFLAGS} to a couple of entries,
5814 added remote-sa.sparc.c
5815 * added remote.sa-sparc.c, a modification of remote.c
5816 which conducts a dialog directly with the SparcStation prom.
5817 * breakpoint.c, infrun.c, sparcdep.c added
5818 remote_insert_breakpoint(), and remote_remove_breakpoint()
5819 to breakpoint.c instead of directly writing breakpoint instructions.
5820 * sparcdep.c on remote_debugging,there is no need
5821 to remove signle step breakpoint instructions.
5822 * main.c added "-epoch" flag and "int epoch_interface" to main.c
5824 * printcmd.c - epoch interface sends lisp expressions to open up
5825 epoch windows on inspection.
5826 * valprint.c - added arrayprint, and addressprint and made adding
5827 format controls easier
5828 * wait.h added a couple of undef's because we were getting
5829 complaints about WSTOPSIG and WTERMSIG begin redefined.
5832 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
5834 * symtab.c (decode_line_1): Add support for handling method stubs
5835 in the type information.
5837 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
5839 * values.c (baseclass_addr): Run loop from INDEX+1 to
5840 N_BASECLASSES; otherwise, we can still get into a loop.
5841 @@ This should be restructured to use a cleaner search strategy.
5843 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
5845 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
5846 abbreviation "Tt" for tags which have the same name as their
5849 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
5851 * symtab.c (list_symbols): add ability to set breakpoints on all
5852 the functions which match a particular regular expression.
5854 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
5856 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
5857 should print ANSI qualifiers (such as `const' and `volatile').
5858 All callers changed to call with ANSI == 1, except from
5859 `check_method_stub', which uses old-style syntax.
5861 * symseg.h (struct fn_field): Remove unneccessary `args' field.
5862 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
5864 * values.c (check_stub_method): New function.
5866 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
5868 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
5869 * valprint (type_print_base): Ditto.
5871 * symtab.c (gdb_mangle_typename): New function.
5873 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
5875 * breakpoint.c (catch_command): New function. Provides a
5876 mechanism to set breakpoints based on catch clauses.
5877 (disable_catch): Similar, but disables breakpoints on catch
5879 (delete_catch): Similar, but deleted breakpoints on catch clauses.
5881 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
5883 * blockframe.c (blockvector_for_pc): New function.
5884 * blockframe.c (block_for_pc): Changed to call
5885 `blockvector_for_pc' and get the block itself.
5887 * stack.c (catch_info): New function. Prints info about
5888 exceptions which can be caught in the current frame.
5889 * stack.c (print_frame_label_vars): New function. Similar to
5890 `print_frame_local_vars'.
5891 * stack.c (print_block_frame_labels): Prints out labels that are
5892 defined in this frame. These labels are exceptions that can be
5895 * dbxread.c: Updated to handle N_CATCH symtab types.
5897 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
5899 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
5900 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
5901 when printing the type.
5903 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
5905 * valprint.c (val_print): Use `baseclass_addr' to access the
5906 baseclasses pointed to via the derived class object at VALADDR.
5908 * values.c (baseclass_addr): New function. Casts derived pointers
5909 to baseclass pointers taking virtual baseclasses and multiple
5910 inheritance into account.
5912 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5916 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5918 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
5919 exp_valid_block field correctly.
5921 * infrun.c (wait_for_inferior): When checking "don't even think
5922 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
5923 also check step_resume_breakpoint.
5924 Insert breakpoints and continue (not step) if
5925 step_resume_break_address != NULL, even if another_trap.
5926 If trap_expected and we enter sigtramp, then set up a
5928 If trap_expected is set when we hit the step_resume_break,
5930 When calling resume and trap_expected says tell resume to step
5931 (2 places), also check step_resume_break_address.
5933 * infrun.c (wait_for_inferior): Don't set
5934 prev_{pc,sp,func_{start,name}} before calling wait ().
5935 Do set them after exiting loop.
5936 Move their declarations outside functions.
5937 (start_inferior): Initialize them.
5939 Thu May 3 00:15:11 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5941 * infrun.c (wait_for_inferior, after check for trap_expected > 1):
5942 Restore old code which distinguishes between trap_expected and
5943 running_in_shell, just make the latter take any non-TRAP signal,
5946 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
5948 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.
5949 xconfig/3b1 (CC,PINSN_CC): Define.
5951 * xconfig/altos, altos-dep.c: Rename altos-dep.c to altos-xdep.c.
5955 * breakpoint.c (bpstat_stop_status),
