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

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

271 generic routines for calling inferior functions.
273 * blockframe.c (inside_main_scope, inside_entry_scope): New.
275 * copying.awk: Filter formfeeds out of copying & warrantee.
276 Make them available as `show copying' and `show warrantee' also.
277 * main.c (print_gnu_advertisement): Advt `show' commands.
279 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)
281 * mach386-xdep.c: Even when cross-compiling, leave in the
282 core-file reading code.
283 * core.c (get_core_registers): Avoid coredump if no .reg section.
285 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
287 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
288 This avoids coredumps under `set print object on' in value_headof
289 (called erroneously by value_from_vtable_info) for `p &struct'
290 or `p *struct'. From Peter Schauer.
292 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
294 * Makefile.in: Roll version to 4.1.2.
295 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
296 size from BFD (but, FIXME, we don't yet read external nlists's and
297 convert them to internal nlists's before handling them -- we still
298 assume they have the same size and alignment.) Use SET_NAMESTRING
300 * exec.c (exec_file_command): Move dead coff-encapsulation code
302 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.
304 Fri Oct 4 22:30:06 1991 John Gilmore (gnu at cygnus.com)
306 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
307 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
309 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
311 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
312 * mips-xdep.c (store_inferior_registers): Don't try to
313 write the (pseudo) FP.
314 * mipsread.c (parse_partial_symbols): Improved algorithm for
315 setting pst->texthigh.
317 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
319 * doc/Makefile: make TEXINPUTS include . everywhere
321 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
323 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
324 vestiges of typevectors, which were for symsegs and are no longer
325 used. (From a question by Eliot Dresselhaus
326 <dresselh@RFT30.nas.nasa.gov>).
328 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
330 * dbxread.c, coffread.c: static-ize functions that were
331 gratuitiously external. (From Fred Fish.)
333 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
335 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
336 until it is large enough.
338 * dbxread.c (read_type): Handle error case slightly better.
339 Make complaint message not C++-specific.
341 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
343 * infrun.c (wait_for_inferior): Fix step/next so that you only
344 stop at the beginning of a new line. This fixes various problems
345 with for loops, nested if-else's and switch statements.
347 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
349 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
350 between symtabs and psymtabs become ordinary error()s.
352 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
353 properly, making "end pc" correct in shared lib psymtabs.
354 (From Guy Harris <guy@auspex.com>.)
356 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
358 * dbxread.c: Enable, but soften, const_vol_complaint.
359 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
360 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
361 should be file-scope, not global.
362 (read_struct_type): Remove ancient multiple-inheritance warning.
363 (read_range_type): Check base type, complain & patch if undefined.
364 * stack.c (frame_info): Demangle the function name in `info stack'.
367 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
369 * eval.c (evaluate_subexp_for_address): Don't use
370 TYPE_POINTER_TYPE directly (it might be zero if this type has
371 never had a pointer created before); use lookup_pointer_type.
372 * symtab.c (lookup_method_type): Arguments were swapped in all
373 callers, so fix it here. I'm amazed this worked at all!
375 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
377 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
378 "bss" rather than "data" symbols, but which still conflict.
381 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
382 * core.c (core_files_info): Shorten output.
383 * exec.c (exec_files_info): Ditto.
384 (build_section_table): Ignore zero-length sections.
385 * language.c, printcmd.c: Lint.
386 * language.h (get_frame_language): Declare.
387 * saber.suppress: update.
388 * stack.c (find_relative_frame): Remove complex code that was
389 #if 0'd, stick with simple code. Lint.
390 * saber.suppress: Update a bit.
391 * symfile.c (add_symbol_file_command): Add "?" to question.
392 * utils.c (parse_escape): Avoid \a due to bdead compilers.
393 * value.h: Declare typedef_print.
395 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
398 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
399 (Reported by Mark Peek <mark@imagen.com>.)
401 * solib.c (solib_map_sections): Relocate all sections, even
402 though only the text section's size is tracked. Mark ld_text
403 for eventual elimination as we generalize to N sections.
405 * infrun.c (wait_for_inferior): Don't check if the PC is in a
406 call_dummy if we were stopped by a random signal that is being
407 passed to the program. This produced wierd results when calling
408 functions in the inferior and signals (e.g. SIGALRM) were in use.
410 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
412 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
413 Bugfix from Paul Eggert <eggert@twinsun.com>.
414 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
415 * valprint.c (print_floating): Print 9 digits for IEEE floats.
418 Mon Sep 23 15:50:07 1991 John Gilmore (gnu at cygnus.com)
420 * Makefile.in: Roll VERSION to 4.1.1.

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

631 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
633 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
634 entries are enclosed herein. Not all of these changes
635 have been merged into the master GDB sources -- check the
636 ChangeLog above here for the merge log.
638 Mon Jun 3 17:05:45 EDT 1991
640 m2-exp.y Created. Tested outside of GDB for a few days. Proper
641 operators were added, C specific operators and tokens
642 removed. yylex() revamped to some extent. Still things
643 missing from the grammar, such as sets.
644 Tested for two weeks in GDB v3.5.
646 Tue Jun 11 17:23:48 EDT 1991
648 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
649 so they are built-in. Sort of a hack.
651 Fri Jun 14 12:53:51 EDT 1991
653 m2-exp.y Added range checking for numeric constants. Any numeric
654 constant is assumed to be of builtin type INTEGER unless:
655 (1) it is octal or hexadecimal, in which case it is a
656 CARDINAL; (2) it is too big to fit into an INTEGER, in
657 which case it is a CARDINAL.
658 eval.c Added simple range checking for +, -, and * on integers.
659 Doesn't work very well for *, since 6 * 1,000,000,000 =
660 1,705,032,704, which fails the simple test of result >=
661 first_operand, no matter in what order the operands are.
663 Tue Jun 18 14:11:30 EDT 1991
665 Broke the parser into parts, one containing the C grammar and the other
666 containing code to be shared by all of the grammars.
668 The following files no longer exist:
673 The following files were added:
675 c-exp.y (The C grammar)
676 m2-exp.y (The Modula-2 grammar)
677 parser-code.c (Code that is shared by the above grammar)
681 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
682 now necessary to use the Bison compiler compiler, since it
683 will generate function/variable prefixes other than yy.
685 Tue Jun 18 16:47:49 EDT 1991
687 symtab.[ch] Added the external variable working_lang, than holds the
688 value of the current working language.
689 Added the ennumerated type language_mode, with the values
690 language_auto and language_manual, the former meaning that
691 GDB sets working_lang as needed, and the latter meaning
692 that the value of working_lang is totally under user
694 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
695 REAL, BOOLEAN and CHAR. Also added the type codes
696 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
697 utils.c Added set_language_command and show_language_command to
698 implement the GDB support commands "set language" and
700 expression.h A number of identifiers were added to the type exp_opcode
701 to facilitate Modula-2 builtin functions, integer
702 division, and array indexing.
704 Wed Jun 19 13:25:58 EDT 1991
706 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
707 if the language specified by working_lang requires the use
708 of strict typing of expressions. Eventually, even this
709 will be able to be changed by the user.
710 Added the macro RANGE_CHECK, which evaluates to non-zero
711 if the language specified by working_lang requires the
712 checking of a value against the domain of its type.
713 Eventually, even this will be able to be changed by the
715 language.[ch] Predicates involving types (simple_type, ordered_type,
716 same_type, integral_type, numeric_type, character_type,
717 boolean_type, float_type) are added. These predicates are
718 based on the current value of working_lang, and are handy
721 Wed Jun 19 15:39:34 EDT 1991
723 eval.c Added the function type_array_rank which computes the rank
725 valarith.c Added the funtion value_bool, which when given a integer
726 value.h value (ie. struct value *) as an argument, it returns a
727 boolean value (ie. struct value *) true if that integer
728 is non-zero, and a boolean value false otherwise.
729 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
730 will print out properly.
732 Wed Jun 19 16:36:34 EDT 1991
734 valops.c Added the function value_capitalize, which returns it
735 value.h argument capitalized if its argument is a lowercase
736 letter, or the argument unchanged if its argument is not a
738 valarith.c Added the function range_check_p, which returns non-zero
739 value.h if its value argument is between the integral bounds upper
741 Added the function range_check_enum_p, which makes sure
742 that its value argument is a valid member of the domain of
744 Added the function range_check_range_p, which makes sure
745 its value argument lies between the upper and lower bounds
746 of its type argument, which must be a ranged type.
747 Added the function check_array_index, which range and type
748 checks an index of an array.
749 Added the function value_multi_subscript, which computes
750 array[idx1,idx2...idxN], given a value array and an array
751 of values representing indicies.
752 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
753 unpack_long to work with TYPE_CODE_BOOL and
756 Wed Jun 19 18:04:08 EDT 1991
758 symtab.c Stored pervasive types in a structure and make
759 lookup_pervasive_type() a lookup function that was based
760 on working_lang. If lookup_pervasive_type() returned
761 non-zero, then that value was returned (a fix, since
762 before it simply wouldn't return the pervasive type.)
763 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
764 non-zero if the language specified by working_lang means
765 "conversion" when it says "cast".
766 valops.c Added the function value_real_cast(), which performs a
767 value.h *cast*, not a *conversion*, which is what value_cast()
768 does when it can. In particular,
769 value_cast(<float_type>,4) = 4.0, while
770 value_real_cast(<float_type>,4) = some mess.
771 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
772 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
773 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
774 and MIN on integral types. *NOTE*: These are currently
775 hardcoded to work only if there are 8 bits per storage
777 eval.c Made logical functions call value_bool to return a
778 properly typed boolean value, based on working_lang.
780 Thu Jun 20 11:55:27 EDT 1991
782 valprint.c Types now print out in a Modula-2 fashion. This works for
783 the cases when the type is printed out step-by-step, that
784 is, it doesn't work when the name of a structured type
785 (which includes the keyword "struct", etc.) is simply
787 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
788 since type specifications in C and Modula-2 are very
789 different. The C printing of a type is very recursive,
790 whereas in Modula-2 it is generally very simple. C has
791 type prefixes and suffixes, which have no real analogue in
792 Modula-2. Maybe type_print() should call a language
793 specific type printer. This is also advantageous if we
794 compile GDB to exclude some of the languages. We'll just
795 leave those functions out.
797 Thu Jun 20 16:57:10 EDT 1991
799 dbxread.c When reading the complete symbol table in (via
800 psymtab_to_symtab()), the number and types of function
801 arguments are added to a function type. define_symbol()
802 calls add_param_to_type() to accomplish this.
803 Assumption: when we come across a function definition
804 (N_FUN symbol with an 'f' or 'F' in the name), its
805 arguments will appear before another function definition.
806 When a function is found, a pointer to its type is placed
807 in the global in_function_type. Changes that
808 add_param_to_type() makes are to this global.
809 valprint.c The type of a function now includes (for Modula-2) the
810 types of its parameters.
811 eval.c Type checking and a check for the proper number of
812 arguments is now done for function calls. Not sure of the
813 impact this has on C++ member function yet.
815 Thu Jun 20 19:58:48 EDT 1991
817 valprint.c Rewrote the type printer. Broke it into two language
818 specific parts, adding the functions type_print_m2() and
820 An unfortunate consequence is this: if you debugging a C
821 program in Modula-2 mode (why?), info types does not work
822 well with regular expressions, since the types are printed
823 out in Modula-2 terminology, but stored in C terminology.
824 language.[ch] Added the functions new_type_last(), type_keyword(), and
825 type_sep() to aid in the printing of typedefs.
826 symtab.c Made the printing of typedefs as language independent as
827 possible through calls to new_type_last(), type_keyword(),
830 Fri Jun 21 11:50:26 EDT 1991
832 dbxread.c Check all incoming ennumerated types. If it looks like
833 Modula-2's BOOLEAN type, then change the type_code of the
834 type to TYPE_CODE_BOOL so we can process it as a boolean
836 valprint.c Replaced some of the 0x%x with calls to sprintf and
837 hexformat() in val_print().
838 language.[ch] Added the function hex_to_string(), which converts its
839 integral argument to a hexadecimal number (format is
840 language based) and returns the result as a string.
842 Mon Jun 24 12:25:07 EDT 1991
844 valprint.c Some functions call type_print_1() directly, instead of
845 value.h using type_print(), so they can specify where (column) to
846 print things. Since type_print() takes care of language
847 dependence, that needs to be called first. Added a
848 parameter depth to type_print() (so it is now like
849 type_print_1). Changed type_print to type_print_at, and
850 made type_print a macro that passes a depth argument of
852 symmisc.c Changed all calls to type_print_1 to calls to
854 Makefile.dist Made it possible to build GDB for a specific set of
855 depend languages. Do this by passing a definition for the macro
856 LANGS to make. LANGS should be a string containing a
857 space-separated list of language names (ie. LANGS="c m2").
858 The default is to build all languages. Note that grammar
859 files must follow the naming convention of <lang>-exp.y.
860 gdb.lang This holds the current value of the LANGS macro. It is
861 examined every time make is called, and is updated if
863 eval.c Added #ifdef _LANG_<lang> to these files.
864 expread.c Still need to add them to dbxread.c and coffread.c.
872 Mon Jun 24 16:33:11 EDT 1991
874 language.[ch] Added the functions hexformat_pre() and
875 hex_to_string_pre(), which take a prefix argument to
876 include in the format string. Thus, hexformat_pre("08") will
877 return "0x08x" (if the working language is language_c).
878 Made hexformat() and hex_to_string() calls to the above
879 with "" as the prefix argument.
881 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
882 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
883 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
884 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
885 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
886 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
887 valprint.c, vax-pinsn.c
889 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
890 calls to hexformat() and hex_to_string(). Format strings without
891 the leading "0x" were ignored.
893 depend Updated to take the above into account.
896 Tue Jun 25 15:27:18 EDT 1991
898 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
899 and type_check_t to keep track of the current state of
900 range and type checking.
901 main.c Added the variables range_mode, range_check, type_mode,
902 and type_check to record the current state of range and
903 type checking. Added initialization code to main().
904 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
908 Tue Jun 25 17:57:08 EDT 1991
910 dbxread.c process_one_symbol() updates the variable (enum language)
911 source_lang based on the extension of the filename
912 contained in the N_SO sybmol that started this symtab.
913 When end_symtab() is called, the value of source_lang is
914 put into the language field.
915 stack.c select_frame() sets working_lang (and possibly type_check
916 and range_check) to the language field of the symtab
917 associated with the frame that is selected if working_mode
918 is language_auto. If working_mode is language_manual, a
919 warning is printed and working_lang is not set.
920 language.c Added the function set_type_range(), which sets the value of
921 type_check and range_check (if their modes call for
922 automatic setting) based on the current value of
923 working_lang. A non-zero argument will cause the current
924 settings to be output.
927 Wed Jun 26 14:51:40 EDT 1991
929 eval.c Added range checks on assignment.
930 m2-exp.y Added the grammar for sets to the language. Currently,
931 these do not do anything except print an error message.
933 Wed Jun 26 17:01:04 EDT 1991
935 m2-exp.y Added the ability for parse_number() to parse negative
936 numbers. A global flag is set upon encountering a unary
937 minus. This was done to make, for example, 1 parse as a
938 CARDINAL, and not as an integer, per Wirth's examples in
939 Programming in Modula-2 ed.4.
940 valprint.c Added support for "set radix 2" by then setting
941 output_format to 't'.
942 eval.c Implemented range checking on subrange types. Added calls
943 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
944 Implemented MIN and MAX for ennumerated types. The
945 minimum value of an ennumerated type is defined by Wirth
946 as the first identifier, and the maximum as the last.
947 m2-exp.y Made octal numbers ending with "B" be characters and those
948 ending with "C" be numbers, per Wirth's book. (p. 34)
950 Thu Jun 27 14:11:52 EDT 1991
952 stack.c select_frame() now only sets working_lang, it does not
953 notify the user. If working_mode is language_manual, then
954 a warning is issued once.
955 main.c At the end of each call to execute_command(), working_lang
956 is checked against the local static (enum language)
957 current. If they differ and working_mode is
958 language_auto, the new settings of language, type and
959 range checking are printed out.
960 stack.c Modified frame_info() to include the language of the
961 current frame in the output of "info frame".
962 language.[ch] Added the function language_str() which returns the name
963 of the current language.
965 Fri Jun 28 15:33:14 EDT 1991
967 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
968 the language. INCL and DECL currently cause an error,
969 since sets are not implemented yet. INC and DEC are
970 implemented as PREINCREMENT/PREDECREMENT with one
971 argument, and as ASSIGN_MODIFY with two arguments.
972 eval.c Added type checking to the above cases.
973 value.h Added not_lval_constant to the lval_type ennumerated type.
974 not_lval_constant means that the value is a constant
975 value; that is 3 or 'a' or TRUE, not as in a constant
976 identifier. This is used to help coerce numbers such as 3
977 to either signed or unsigned numbers.
978 valops.c Added the function value_coerce_constants() which coerces
979 constant integers as following: if one is a constant and
980 the other is not, the constant's type is set to the type
981 of the other argument. If both are constants and one is
982 signed, the other is converted to a signed constant.
984 Sat Jun 29 17:26:29 EDT 1991
986 valarith.c Added a better range checker. It now checks range
987 (successfully) on integral operations [+-] (signed and
988 unsigned) for any C sized type. Still does not work well
990 int_in_size() returns an integer that is coerced to fit into
991 specified number of bytes.
993 Mon Jul 1 13:04:14 EDT 1991
995 language.[ch] Added the function binop_result_type(), which returns the
996 builtin (struct type *) type that would be the result of a
997 binop on the two values V1 and V2.
999 Wed Jul 3 19:22:53 EDT 1991
1001 source.c Extended source_info() to include the source language in
1002 the output from "info source".
1004 Fri Jul 5 13:48:52 EDT 1991
1006 utils.c Moved the support functions for the GDB set/show commands
1007 dealing with language into language.c.
1008 language.c Added the function language_info(), which displays info
1009 about the current working language, type and range check
1010 settings. Called via the GDB command "info language".
1011 Added an initialization routine _initialize_language(),
1012 that sets defaults for the language, type and range
1013 variables and sets up the new GDB commands.
1014 main.c Language setup moved to language.c.
1017 Mon Jul 8 10:10:22 EDT 1991
1019 valarith.c Debugged the range checker for arithmetic. Still does not
1020 work for multiplication very well.
1022 Mon Jul 8 12:40:37 EDT 1991
1024 language.[ch] Added the function value_true() which returns non-zero if
1025 its argument represents a boolean true value.
1026 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1027 check the truth of an expression.
1029 Thu Jul 11 12:51:34 EDT 1991
1031 language.[ch] Added the predicate structured_type(), which returns
1032 non-zero if the argument is a structured type.
1033 Added the predicate pointer_type(), which returns non-zero
1034 if the argument is a pointer type.
1035 eval.c Added the ability to do addition and substraction on
1036 pointers and integers. This case simply bypasses the
1039 Thu Jul 11 14:41:42 EDT 1991
1042 Added the symbol N_DEFD (0x4a) which is a definition
1043 module dependency that is used by the GNU Modula-2
1044 compiler and the linker. It is not important to GDB,
1045 except that [dbx|coff|mips]read.c should ignore these
1048 Fri Jul 12 16:07:00 EDT 1991
1050 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1051 0 in val_print(). Also added statements to the else part
1052 to coerce type (argument to val_print) to a pointer type
1053 if it is an "array of unspecified length".
1054 valops.c Added the function value_m2_string(), which returns a
1055 (value) value which is a constant string, whose type is
1056 (ARRAY [0..n] OF CHAR). The length field of the type
1057 structure is set to zero, so it will be interpreted as an
1058 "array of unspecified length".
1059 stack.c Moved the language/frame mismatch check to
1060 main.c:execute_command().
1061 main.c The working language is recorded each time
1062 execute_command() is executed. If working lang has
1063 changed during its execution, then the new
1064 language/type/range info is printed out for the user. If
1065 the working language does not match the language of the
1066 frame, a warning is issued.
1068 Sat Jul 13 16:16:39 EDT 1991
1070 eval.c Moved all the type-checking stuff for operators to
1071 language.[ch] language.c. This is so we can keep language-specific
1072 stuff (like for what type operators are defined) in
1074 language.[ch] Added the function binop_type_check(), which checks to see
1075 if its two (value) arguments are type-compatible with its
1076 opcode argument. The opcode should represent an operation
1077 involving an operator. Also added the macro function
1078 unop_type_check, which calls binop_type_check with a
1079 NULL second argument.
1080 expprint.c Added Modula-2 operators to the op_print_tab, so info
1081 expression.h break works correctly. Also added "op_string", which
1082 returns the string corresponding to the (enum exp_opcode)
1083 opcode that is its argument.
1086 Sat Jul 13 18:26:18 EDT 1991
1088 coffread.c Added code to record the type of function arguments with
1089 each paricular function. Code is very similar to that
1091 dbxread.c Moved add_param_to_type() to symtab.c
1092 symtab.[ch] Added function add_param_to_type() from dbxread.c
1094 *** NOTE: The above additions have not been tested.
1096 Mon Jul 15 12:50:47 EDT 1991
1098 langauge.[ch] Added the functions type_error and range_error, which work
1099 like error() except if the type/range mode is set to
1100 *_mode_warn, then they do not do a return_to_top_level(),
1101 but merely print a warning.
1102 Also changed [set|show]_[type|range]_command() to support
1103 the new "warn" feature.
1105 Thu Jul 18 17:50:54 EDT 1991
1107 mipsread.c Added code to record the type of function arguments with
1108 each particular function. Code is very similar to that
1111 *** NOTE: The above additions have not been tested.
1113 Fri Jul 19 11:19:10 EDT 1991
1115 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1116 UMIN_OF_SIZE, which when given a size of a numeric type,
1117 return the maximum and minimum value it can hold. UMAX...
1118 and UMIN... return the result for unsigned types.
1119 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1120 struct types. They call above macros.
1121 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1122 avoid a name conlict with the above.
1123 c-exp.y Added range checking on numeric constants in
1124 parse_number() for completeness.
1125 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1126 return 0 if working_lang is not language_c.
1128 Thu Aug 8 14:17:22 EDT 1991
1132 breakpoint.c Documentation strings of some commands changed to
1133 eliminate the references to the C language where
1136 Tue Aug 13 15:48:03 EDT 1991
1138 m2-exp.y Added qualified identifiers to the grammar. The semantics
1139 are slightly different from those of the GDB operator ::
1141 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1142 type_exp, where type_exp is any valid type expression.
1144 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1145 printcmd.c Modified ptype_command() so it actually parses the input
1146 (necessary for type expressions with scope qualifiers).
1147 Added the function ptype_eval() which expects an
1148 expression composed of one OP_TYPE element.
1149 *.[ch] Replaced all occurences of parse_c_expression with
1151 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1153 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1155 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1157 Small fixes from Peter Schauer:
1159 * infrun.c (child_attach): Lint.
1160 * solib.c (find_solib): Handle shared libs version 2.
1162 Small fixes from David Wood:
1164 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1168 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1169 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1171 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1172 chars_per_line is at maximum (user typed `set width 0'). Fix
1173 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1175 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1177 * coredep.c: include ptrace.h where necessary.
1178 * mipsread.c(parse_lines): fix unsigned char problem that was
1179 messing up line numbers on SGI's and possibly other MIPS based
1181 * infrun.c (child_create_inferior): use better test to check
1182 return val from setpgrp().
1183 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1184 for sgi/irix support.
1186 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1188 * mipsread.c (parse_symbol): Put non-static procedures
1189 in the global block.
1191 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1193 Patch together `text_start' and `text_end' for 29K port.
1195 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1196 variables and set them based on the exec file.
1197 * am29k-tdep.c: declare text_start.
1198 * valops.c (call_function_by_hand): declare text_end.
1200 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1201 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1202 because machines that do this will also have to know to
1203 set NEED_TEXT_START_END. Besides, it was a redundant way to
1205 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1206 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1207 NEED_TEXT_START_END.
1209 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1211 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1213 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1214 Pass MUNCH_DEFINE to munch whenever we run it.
1215 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1216 format string; use 0x%x instead.
1217 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1218 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1219 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1220 * inflow.c: Handle `short' process group IDs.
1221 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1222 and check for ptrace errors.
1223 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1224 (coff_symfile_init): Initialize text_bfd_scnum.
1225 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1226 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1227 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1228 Merge target arm case with other "easy" cases. Add target
1229 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1230 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1232 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1233 * munch: Cope with RT/PC putting fns in data segment.
1234 Restore ability to override `nm' by specifying MUNCH_NM.
1235 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1236 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1237 and remote-adapt. Remove encapsulated coff #define's (the
1238 support should go in BFD, and gdb shouldn't know or care).
1239 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1240 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1241 * tm-29k.h: Update BADMAG (though it should go away).
1242 Allow the register definitions to be overridden in another
1243 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1244 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1245 DUMMY_SAVE_GR96, for handling kernel calling conventions
1246 that use GR64+ rather than GR96+.
1247 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1248 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1249 overrides various things.
1251 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1252 child_attach does, making a clean stop in the newly attached
1254 * remote-eb.c: Lint.
1256 * coffread.c: Make coffread independent of any particular
1257 variant of COFF. Avoid #include-ing any particular one except
1258 internalcoff.h. BFD now passes key values for symbol reading
1259 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1260 and the symbol masks and shifts); use them.
1261 Remove obsolete end_of_text_addr.
1263 * exec.c: Remove unused include files.
1265 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1267 * Makefile.in (documentation targets): Pass $(M4).
1268 Bugfix from eggert@twinsun.com (Paul Eggert).
1270 * stack.c (down_silently_command): Check for stack existence.
1272 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1274 * Makefile.in (VERSION): Update to 4.0.3.
1276 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1278 * core.c (core_file_command): Print frame at coredump with
1279 its level number, by calling print_stack_frame.
1280 * frame.h: Add selected_frame_level, print_stack_frame.
1281 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1282 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1283 Change print_sel_frame and print_selected_frame callers to
1286 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1287 * symfile.c (free_named_symtabs): Ditto.
1288 * main.c (main): wrap_here needs an arg.
1289 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1290 (solib_add): Avoid noise.
1291 (solib_create_inferior_hook): Lint.
1292 (sharedlibrary_command): Move dont_repeat to here.
1293 * utils.c (error): Call wrap_here to force buffered output.
1295 Small patches from Peter Schauer:
1297 * coffread.c (start_symtab): Free any existing line_vector before
1299 (read_coff_symtab): Ditto for type_vector.
1301 * source.c (lines_to_list): New variable, replacing function.
1302 (all uses): Use as variable.
1303 (_initialize_source): Add 'set listsize' and 'show listsize'.
1304 * utils.c (lines_to_list): Remove function.
1305 * stack.c (print_frame_info): Use as variable.
1306 * defs.h (lines_to_list): Remove declaration.
1308 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1310 * breakpoint.c (insert_breakpoints): Restore warning about
1311 the program might be running in another process, but only for
1312 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1313 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1315 * utils.c (error): if error_pre_print is set, print the string
1317 * main.c (main, print_gnu_advertisement, print_gdb_version):
1318 Reformat legalese so it always prints, but acts as an "I'm here"
1319 message while symbols are being read. If any errors occur,
1320 print a few newlines to set off the message and start it at the
1321 left margin. Remove mention of "help" command, and don't yak
1322 about symbol reading.
1323 (catch_errors): Error string is now printed first in case of
1325 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1326 suggest the "help" command.
1328 * Makefile.in (VERSION): Set to 4.0.2.
1330 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1332 * .gdbinit: Remove useless "rr" command. Set complaints
1333 to 1 for people debugging gdb.
1335 * breakpoint.c, remote-vx.c: Reword strings printed by
1336 catch_errors callers.
1338 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1340 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1341 (Fix from kenc@viewlogic.com.)
1343 Fix some infrastructure to be able to cope with host and target
1344 machines with different sized basic types (ints, ptrs, etc).
1345 (Idea from pierre@la.tce.com (Pierre Willard).)
1347 * values.c (value_from_longest): Rename from value_from_long.
1348 Handle pointer types as well as integers, so that targets with
1349 different pointer sizes from the host can be accomodated.
1350 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1351 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1352 uses of value_from_long to value_from_longest.
1353 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1354 the correct pointer type to value_from_long{est}.
1356 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1358 * remote-vx.c: Remove obsolete code for calling functions via
1359 vxworks kludge interface (it referenced value_from_long).
1361 * valops.c (value_string): Find malloc with lookup_misc_func, not
1364 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1366 Make writing to files work properly. (Fixes to BFD are also needed.)
1368 * core.c (core_open): Open file ourselves, read or r/w, depending on
1369 write_files. Use bfd_fdopenr.
1370 * gdbcore.h (write_files): New variable.
1371 * exec.c (write_files): Define variable, add set&show for it.
1372 (exec_file_command): Use write_files to open for read or r/write.
1374 Make shared library reading happen automatically. These changes
1375 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1377 * inferior.h (stop_soon_quietly): Add to exported variables.
1378 * infrun.c (child_create_inferior): call solib hook, if defined.
1379 (child_attach): call solib hook, if defined.
1380 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1381 (find_solib): Use lookup_misc_func rather than hand-rolled.
1382 (symbol_add_stub): New stub for catch_errors.
1383 (solib_add): Avoid output if !from_tty. Catch errors rather
1384 than just calling symbol_file_add and bombing.
1385 (solib_create_inferior_hook): Interface with the target process
1386 to let it read and alloc shared libs, then figure out what it did.
1388 * core.c (validate_files): Fix typo, soften warning.
1389 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1391 * utils.c (fputs_demangled): Avoid duplicate printing if
1392 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1394 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1395 (Fix from pierre@la.tce.com (Pierre Willard).)
1397 * main.c (catch_errors): Change argument to a char * from an int,
1398 since a char * can point to a struct full of glop, but an int
1399 is not guaranteed to be able to hold a pointer.
1400 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1401 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1402 * core.c (core_open, solib_add_stub): Adapt.
1403 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1405 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1407 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1408 by adding .NOEXPORT target.
1410 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1414 * Makefile.in (VERSION): Roll to 4.0.
1415 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1417 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1419 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1422 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1425 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1427 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1428 reflect above name change
1430 * WHATS.NEW: correct pointer to refcard.
1432 * doc/gdb.texinfo: update New Features, Installing
1434 * doc/gdbint.texinfo: add short description of configure +template
1436 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1438 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1440 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1442 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1443 tar file, add dependencies for referenced doc files.
1445 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1447 * coffread.c, symfile.c, stack.c: saberized.
1449 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1451 * doc/refcard.tex: permuted Essential Commands sec
1453 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1455 set/show symbol-reloading
1456 default set complaints 0
1458 RET-repeat disabled after prompted long displays
1459 processID (attach) interpretation of 2nd GDB cmdline arg
1461 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1463 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1464 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1465 breakpoint.c, main.c: lint.
1467 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1469 Install new configuration scheme for GDB and friends.
1471 * config.sub: Translate ordinary names to three-part names.
1472 * configure: Use three-part names internally.
1473 * configure.in: Translate three-part names to filenames.
1475 * README, WHATS.NEW: Update for gdb-4.0.
1476 * Makefile.in: Roll VERSION to 3.99.
1478 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1480 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1481 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1482 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1483 to single structures rather than arrays; when passing
1484 their address, use &. This avoids trouble with bdead compilers.
1485 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1486 instead. This avoids portability headaches.
1487 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1489 * source.c (open_source_file): Avoid ANSI const bdeath by
1490 skipping declaration and then casting result value.
1491 * tm-hp300bsd.h: Clarify comment.
1492 * utils.c (strstr): Result is const char *; ANSI bdeath.
1493 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1494 since system include file defines it differently from "defs.h",
1495 though the two are equivalent for our purposes.
1496 * tconfig/hp300bsd: Add m68k-tdep.o.
1498 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1500 * tconfig/sun*4: Remove warnings about system assembler.
1502 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1504 * mcheck.c: Avoid warning about undeclared abort fn.
1505 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1506 it causes recursive calls to error() when used in cleanups.
1507 To do so requires that we make it a function, so we do.
1508 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1509 * utils.c (do_cleanups): Remove the current cleanup from the
1510 chain *before* calling it, in case error() is called from it.
1511 The result won't be pretty, but won't be an infinite loop either.
1513 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1515 * dbxread.c (read_struct_type): Grok anon structs for C++.
1516 (vb_name, vptr_name): Null terminate these strings.
1518 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1520 Minor bug fixes from BSD Net2 gdb:
1522 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1523 returns 0, there is no previous frame.
1524 * breakpoint.c (commands_command): If !from_tty, don't call
1525 input_from_terminal_p().
1526 * dbxread.c (record_misc_function): Speed up slightly.
1527 (compare_psymbols): Ditto.
1528 * infcmd.c (do_registers_info): Take a second argument to
1529 determine whether to print float registers. "info registers"
1530 does not do so anymore. "info all-registers" does, now.
1531 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1533 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1534 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1538 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1539 executing_breakpoint_commands if we are interrupted by error.
1540 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1541 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1542 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1543 catch_errors() so we can setup the frame regardless of whether
1544 the shared libs work.
1545 * ieee-float.c (double_to_ieee_extended): Get exponent from
1546 right place in little-endian systems. From John Carey.
1548 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1550 * main.c: Remove unused terminating_signals and catch_termination().
1551 (long_options): Terminate with a zero element.
1552 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1553 (gdb_readline): Make call-compatible with readline.
1554 (init_signals): Improve comments re vfork vs. signal.
1556 * utils.c (prompt_for_continue): Use new gdb_readline().
1557 If we prompt for continuation, we don't let CR repeat the previous
1558 command, once we get back to a prompt. It's too easy to keep
1559 hitting CR, expecting "--more--" prompts, and have some long
1560 command start repeating on you.
1562 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1564 * blockframe.c (frameless_look_for_prologue): Speed up by
1565 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1566 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1567 Define two variants, one faster.
1568 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1569 and return zero, rather than giving an error.
1570 (setup_arbitrary_frame): Initialize the PC in the new frame.
1571 (skip_prologue): Add a second arg saying whether we're just
1572 checking for a frameless function or not.
1574 * core.c (core_open, core_close, core_xfer_memory): Move
1575 section table pointers and bfd* into the target_ops.
1576 (core_open): Allow errors in shared lib reading, etc.
1577 (core_files_info): Describe shared library sections.
1579 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1580 exec_files_info, set_section_command): Move section table
1581 pointers and bfd* into the target_ops.
1582 (add_to_section_table): Add BFD to section table.
1584 * target.c (target_xfer_memory, target_info): Pass target to
1585 xfer_memory and target_info functions.
1588 * gdbcore.h: Move struct section_table.
1589 * target.h: New home of struct section_table.
1591 * solib.c (solib_add): New argument is the target_ops whose
1592 section list is to be added to, if any. Reallocate the
1593 sections in that target to add any that come from shared libs.
1594 (throughout) so_sections renamed to sections.
1595 (solib_xfer_memory): Deleted.
1596 * tm-sunos.h (SOLIB_ADD): Add target argument.
1597 (SOLIB_XFER_MEMORY): Delete.
1599 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1600 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1601 from target_ops. It's the same on all targets. Add two section
1602 pointers to target_ops.
1604 * stack.c (find_relative_frame): Dump ancient algorithm for
1605 "down", just use handy "next" pointers.
1606 (frame_command): Don't error if there is no stack; let user
1609 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1610 modifies static state in the parent process; new_tty itself
1611 runs in the child and modifies the child's file descriptors
1612 to match the saved static state.
1613 * infrun.c (child_create_inferior): Call new_tty_prefork,
1616 * infptrace.c (child_xfer_memory): Add ignored target arg.
1617 * remote-eb.c (eb_xfer_inferior_memory): ''
1618 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1619 * remote-vx.c (vx_xfer_memory): ''
1620 * remote.c (remote_xfer_memory): ''. Rename from
1621 remote_xfer_inferior_memory.
1623 * main.c (main): Only try to attach "corefile" argument if
1624 it starts with a digit.
1626 * symfile.c (symbol_reloading): New "set/show" variable.
1627 (symbol_file_add): Shorten message about symbol reading.
1628 (add_symbol_file_command): Merge with add_syms_addr_command,
1629 since this should work on all targets now.
1630 (stop_whining): Default to zero, to shut up complaints
1631 about bad symbol tables on many systems.
1632 (free_named_symtabs): Just exit unless symbol_reloading.
1634 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1635 and add comment explaining shared library screw.
1637 * source.c: #if defined => #ifdef.
1639 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1641 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1643 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1645 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1646 (doc/Makefile knows how to make one for local config)
1648 * Makefile.in: use doc/Makefile for doc targets
1650 * doc/Makefile: GDB documentation now has its own Makefile
1651 doc/refcard.tex: renamed from "gdbrc.tex"
1652 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1653 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1656 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1658 * values.c (baseclass_addr): When reading target memory, use the
1659 length of the basetype, not the upper type. We've only malloc'd
1660 enough space for the basetype, leading to errors in free().
1662 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1663 ends up as a function specially, since we know the actual type of
1664 the pointed-to address. This (somewhat) fixes display of
1665 expressions that include misc_function_vector names. Try `cond 1
1666 !strcmp("a","b")' then `i b'.
1668 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1669 The child can be proceeded from inside wait_for_inferior in
1670 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1671 getting skipped in that case.
1673 * expprint.c (print_subexp): Use filtered output, since the
1674 subroutines we call use it, otherwise the output is horribly
1675 mangled, since output of wrappable stuff comes out late.
1677 * Makefile.in: Bump VERSION to 3.98.1
1679 * infrun.c (child_create_process): Use execlp to find the
1680 shell to exec our target program. This requires some fiddling
1681 with `environ' since there is no execlpe().
1683 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1685 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1686 Minor rearrangement of refcard permits two new make targets--
1687 gdbrc.dvi DVI output for refcard, using CM fonts
1688 gdbrc.ps PostScript refcard, using PS fonts
1690 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1694 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1695 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1697 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1699 * doc/gdb.texinfo: last changes for release.
1700 Minor typo and formatting fixes; incorporated most fixes remaining from
1701 filed mail commenting on earlier drafts.
1703 Added warnings: pipes don't work in run command;
1704 conditions are converse of assertions;
1705 step over fn without debug info goes to next fn;
1706 vars may have "wrong" values near fn entrance, exit
1708 Added example from Kingston on printing repeated nonadjacent values
1710 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1711 shell mode for signals
1713 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1714 doesn't sound so much like its parent "Stopping and Continuing"; also
1715 moved entries on continue to top of section, so they don't get lost.
1717 Improved installation directions in appendix, added manual formatting
1720 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1722 * configure.in: Remove xm.h and tm.h even if we aren't linking
1723 new ones, so "./configure sun4; ./configure none" does the right
1724 thing. Assume that alldeps.mak and depend are already built in
1725 srcdir, and avoid running "make" (particularly "make depend",
1726 which involves "gcc") from inside configure. Build Makefile
1727 directly rather than building Makefile.conf first.
1728 * configure: Regenerate with above changes.
1729 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1730 to 3.98. Revise gdb.tar.Z procedure to produce a file
1731 called gdb-$(VERSION).tar.Z but which unpacks into a
1732 directory called "gdb". Move non-source files out of
1733 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1734 (depend): Don't try to do "gcc expread.y".
1735 (expread.o): Update dependencies by hand.
1737 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1740 Fixed a variety of small typos that prevented info from formatting
1741 cleanly; altered too-long heading for GPL Appendix, as discussed
1742 w/RMS; Changed date on cover to July 91.
1744 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1747 (1) Applied some fixes due to comments from Larry Breed (easier ones
1748 through chapsec 5.2)
1749 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1750 it's broken in latest texinfo
1751 (3) Introduced *some* use of [] for optional arguments, where
1752 explanation is not simpler by listing cmd w arg and cmd w/out arg
1753 separately. Still not using @deffn.
1754 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1755 couple of headings are too long. Need patches to texinfo or revision
1758 * Partial update to README (which still needs work for this
1759 release!): (1) use of configure corrected for new script,
1760 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1762 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1764 * symtab.c (lookup_symbol): Don't complain right off about
1765 no debug symbols; use the misc function vector first.
1766 (list_symbols): Use misc function vector to find symbols
1767 that don't have debug info, and print them.
1768 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1769 PC range doesn't match symtab PC range, as it does on the
1770 MIPS because our symtab reading isn't perfect.
1772 * dbxread.c (dbx_symfile_read): Make warning about
1773 "no debug symbols" slightly nicer.
1775 * source.c (select_source_symtab): If "main" symbol exists,
1776 but decode_line_spec can't find line info, don't just return
1777 a zero; try other source symtabs or give an error.
1779 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1780 their low addresses first, then rip through fixing high addrs.
1782 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1783 <runene@ifi.uio.no>.
1784 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1786 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1788 * Minor, mostly mechanical, cleanup of doc subdir for clean
1789 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1790 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1792 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
1794 Mostly MIPS and general symbol-reading fixups.
1796 * doc/gdbint.texinfo: Add documentation on symbol-reading
1799 * mipsread.c: Remove kludges around #include "ecoff.h".
1800 Remove redefinitions of a_magic, etc, no longer used.
1801 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
1802 Fix global overview comments to match symfile.c protocol.
1803 (mipscoff_new_init): Eliminate cur_hdr if we have one.
1804 (mipscoff_symfile_read): Eliminate unused code. Avoid
1805 sorting all the symtabs, when all we have read here is psymtabs.
1806 The symtabs are sorted as they are created anyway. Tell
1807 condense_misc_bunches whether we're mainline.
1808 (psymtab_to_symtab_1): Pass filename when recursing, to make
1809 stack trace more informative.
1810 (parse_partial_symbols): Assume cur_hdr as argument.
1811 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
1812 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
1813 the TYPE_NAME of char *, since that's done in symfile.c.
1814 (free_numargs, parse_symbol, add_symbol, add_block,
1815 shrink_linetable): Declare these fns void.
1816 (upgrade_type): Convert tree of if's to switch. Clean up
1817 bogus "off == 0" handling with a complaint. Avoid setting
1818 field bitpos and bitsize of array with lower and upper bounds.
1819 Check specified bitsize of elements against their actual type's
1820 bitsize, and complain if different. Complain about unknown
1822 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
1823 (psymtab_to_symtab_1): Print names of subsidiary files that
1824 are being read in. FIXME, we read far too many files. This code
1825 is not the problem, the problem is in parse_fdr where the psymtabs
1827 (cross_ref): Result should indicate that we used one aux entry
1828 normally, or two if we encountered a "next" entry. This used
1829 to leave the caller pointing at the wrong aux entry.
1830 (add_symbol): If overflowed cur_block, reallocate it larger,
1831 chase all pointers to it, and complain(), rather than clobber memory.
1832 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
1833 (new_field): Only allocate one field initially, not two.
1834 Pull ++ out of macro argument. Simplify.
1835 (_initialize_mipsread): Avoid initialization of importd
1836 global_psymbols and static_psymbols.
1838 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
1839 to properly set pst->symtab; avoid searching for it.
1840 (symfile_fns): Improve comments, add a FIXME.
1841 * dbxread.c: Update comments to reflect symfile protocol.
1842 (read_ofile_symtab, end_symtab): Return the symtab.
1843 (psymtab_to_symtab_1): Set pst->symtab.
1845 * coffread.c (coff_symfile_read): tell condense_misc_bunches
1846 whether we're mainline.
1848 * symfile.h (sym_fns): Remove unused sym_discard member.
1849 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
1851 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
1852 the environment variable is not.
1853 * infcmd.c (finish_command): Use filtered printfs.
1854 * cplus-dem.c: Add struct tags to a few unnamed structs.
1855 * valops.c (value_coerce_array): Improve comments.
1856 * valprint.c (type_print_varspec_suffix): Print array size only
1857 if greater than zero.
1858 * m88k-tdep.c: Shift some lines left by one space, that had
1859 apparently been trashed at some point.
1860 * TODO: More things to do, a few got done.
1862 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1864 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
1865 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
1867 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
1868 * expread.y, findvar.c, symmisc.c: Ditto.
1869 * printcmd.c (address_info): Update printed forms of LOC_
1870 symbols. Elim LOC_EXTERNAL.
1871 (print_frame_args): Keep track of param stack offsets before
1872 re-looking up to find the local register param is kept in.
1874 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
1875 Further integration of mipsread into gdb. Eliminate unused
1876 routines, duplicate declarations. Handle static symbols in
1877 psymtabs as well as external symbols. When reading symtabs,
1878 insert symbols into the correct block (global, static, or a local
1880 (read_mips_symtab, parse_partial_symbols): Don't pass useless
1882 (mipscoff_symfile_read): Don't call select_source_symtab.
1883 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
1884 rather than SYMBOL_VALUE.
1885 (parse_external): Comment clobbering of top_stack.
1886 (parse_partial_symbols): Update comments. Allocate and parse
1887 static symbols as well as external symbols. FIXME, enum values
1888 are not handled in this pass, but should be. Inline new_psymbol.
1889 Use SYMBOL_VALUE_ADDRESS.
1890 (psymtab_to_symtab_1): Read symbols into global static block
1891 by default (until enter some function's local block context).
1892 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
1893 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
1895 * source.c (select_source_symtab): Select a source symtab
1896 from either the symtabs or, failing that, the psymtabs.
1897 (list_command): Update error message.
1898 (forward_search_command, reverse_search_command): Use getc, not
1899 fgetc, for speed. FIXME, add comment about buffers that die if
1900 overrun by long line.
1902 * values.c (unpack_field_as_long, modify_field): Avoid shifting
1903 by an entire word, which is not portable, if we have a 32-bit
1904 field. (Code in dbxread.c already turns such bitfields, if
1905 aligned, into ordinary ints, but fixing this will help for other
1906 symbol formats and for future changes.)
1907 * core.c (core_open): Handle ANSI const brain death.
1908 * utils.c (vprintf): Fix varargs typo.
1910 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1912 * findvar.c (find_var_value): Handle &function better.
1913 * TODO: Document work needed on &fn and &array.
1914 * printcmd.c (print_address_symbolic): New arg is the prefix
1915 to print if a name is printed.
1916 (print_address_demangle): Honor "set print address" now.
1917 Use new arg above to improve spacing of output.
1918 * valprint.c (val_print): When printing function pointers,
1919 print symbolic form too.
1920 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
1922 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1924 * core.c (memory_error): Reword error msg to mislead less.
1926 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
1928 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
1929 parse_partial_symbols): Use newer BFD internals (external_filehdr
1930 and external_aouthdr), byte-swap the fields that we care about
1931 before using them, and make the file header data local to
1932 read_the_mips_symtab rather than global.
1934 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
1936 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
1937 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
1939 * main.c (command_line_input): Flush stdout and stderr
1940 before every call to readline. This reportedly fixes a bug
1941 that comes up in Sys V running emacs-gdb and/or xxgdb,
1942 when stdin/out are pipes or sockets.
1944 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1946 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
1947 Avoid declaring Makefile dependencies, because GNU Make stupidly
1948 tries to update it if we do.
1950 * coffread.c: Revise for minor changes to bfd internal coff
1953 * configure: If -template= is given a relative path, make it
1954 absolute before recurring in subdirectories.
1956 * configure, configure.in, Makefile.in: Install "configure" script
1957 as replacement for config.gdb.
1958 * config.gdb, Makefile.dist, Makefile.sdir: Remove
1959 * README: Update for configure, mostly. FIXME.
1961 * Add dec3100 as equivalent to littlemips. Indicate in all host &
1962 target config files that they are for the host. When the lines
1963 get copied into the Makefile, this makes it more obvious what's
1966 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1968 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
1969 tabs, which end up in the disassembler output inadvertently.
1971 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1973 Make it compile cleanly in an ANSI GCC2 environment.
1975 * blockframe.c: <stdio.h>
1976 * cplus-dem.c: free takes a void *, ifdef __STDC__
1977 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
1979 * defs.h (alloca): Avoid doing anything if alloca already def'd.
1980 * stddef.h, stdlib.h: Remove these files.
1981 * symtab.c: Avoid declaring qsort, close.
1982 * symfile.c: Avoid declaring close.
1983 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
1984 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
1986 Assorted other changes.
1987 * dbxread.c: include "libaout.h", not "liba.out.h".
1988 * printcmd.c (print_frame_args): Set recurse properly for
1989 indentation of struct and array parameters.
1990 * valops.c (value_cast): Allow cast to void.
1991 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
1992 single_step() in a target-independent fashion.
1993 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
1994 set up to be ready to continue. This makes us target independent.
1995 * infptrace.c (child_resume): Remove call to single_step; now
1996 can single step a SPARC target of any kind.
1998 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2000 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2001 docn into separate sections---basically chapters, plus two loose
2002 pieces that can be configured to go in different places. This
2003 allows GNU m4 to preprocess the manual without coredumping.
2005 * Makefile.dist: tell TeX where to find texinfo.
2007 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2009 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2010 the new target "rdl-apps.texinfo" which captures the Makefile
2011 variable that records where to find the Readline libraries.
2013 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2015 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".

2018 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2020 * README: Update for release 3.95.
2021 * config.gdb: Don't create readline dir in subdir builds.
2022 * main.c: Include with "..." form for non-system include files,
2023 so "gcc -MM" for "make depend" works.
2024 Include readline files with "...h" rather than <readline/...h>.
2025 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2027 * coffread.c: Undo minor damage done by Rich Pixley. Use
2028 different internal and external representations of COFF
2029 data structures. Use new BFD routines for swapping them in and
2031 * symfile.c (free_named_symtabs): Avoid freeing file names that
2032 are null or empty. Old i960 tools seem to produce files that
2033 claim to have empty names, causing each successive file read
2034 to blow away the previous one.
2035 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2036 Move deferred_stores to top of file, but don't separate its
2037 #define's from its variable. Add commentary.
2038 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2039 favor of keeping the (working) config.gdb. Move readline
2042 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2044 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2046 * infptrace.c (fetch_registers): no result, since now void.
2047 * tconfig/news: target depends on m68k-tdep too.

2051 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2054 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2055 applied various small fixes due to or inspired by RMS comments
2057 * doc/gdb.texinfo: finished using all RMS comments, save those for
2058 appendices on readline and cmd history (which are in other source
2061 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2063 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2064 chapter 9; (2) documented 'break' command's menu mode for
2065 overloaded names, in response to hgs problem report C++ p-31
2067 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2069 * doc/gdb.texinfo: (1) better introductory example; (2) more
2070 consistent use of @code, @samp, @file, @kbd throughout; small
2071 cleanups to first three nodes; (3) new "Contributors" node;
2072 (4) Appendix, Renamed Commands; (5) divert specialized startup
2073 instructions to "Targets" chapter for generic manuals, while
2074 leaving them up front for manuals specific to specialized
2075 environments; (6) apply fixes from RMS comments through chapter 4.
2077 * pretex.m4: modify explanatory text slightly (and redefine
2078 "regexp") to keep GNU m4 from complaining. (It still crashes
2079 later, but one step at a time...)
2081 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2083 * readline/readline.c (update_line): Avoid dereferencing a pointer
2084 before comparing it to its bounds. Saber caught this.
2085 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2086 and only set PC if tgetstr returned non-null. Saber caught this.
2088 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2090 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2091 stuff for config manual) here where it counts; updated
2092 to use new subdir structure (gdb/doc/).
2094 * Makefile: generated from above via
2098 * gdbint.texinfo: added instructions on generating gdb.info* files
2099 locally for release. These are ordinary info
2100 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2101 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2102 to generate these, so we distribute them already formatted.
2104 * gdb.texinfo: included full Info node and menu crud (as generated
2105 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2107 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2108 put in comments-for-future gdb.info target (one day makeinfo will
2111 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2113 * gdb.texinfo: Updated to include new or old undocumented
2114 commands, at least the following (perhaps some others I forgot to
2115 record): info f, info float, info path, info program, info s, info
2116 set, info source, info terminal, info types, info user, set/show
2118 Also covered all recent GDB command renames for v4.
2120 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2122 * mipsread.c: Rather than keeping count of how many symtabs
2123 and psymtabs we have, for sorting purposes, count them when
2124 we need to sort. This fixes bug in rereading of symbol tables.
2126 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2128 * infcmd.c: renamed "info path" to "show paths"

2143 symtab.h, target.c, target.h: Lint.
2144 * core.c: setup and select frame after reading shared libs,
2145 else reading shared libs will clobber them. Lint.
2146 * utils.c (error): Force out any buffered wrap text.
2148 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2150 * remote.c: Remove decls of memory_insert_breakpoint
2151 and memory_remove_breakpoint, no longer used. (Suggestion of
2154 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2155 to make it easier to interface to "configure"'d libraries.
2157 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2159 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
2160 aliases for set/show print.

2669 target.c: Add target_preopen and target_command.
2671 (add_target): Call add_cmd and mess with targetlist->doc.
2672 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
2673 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.

2703 command is add-symbols.
2704 * target.c (dummy_target): Permit add_syms_addr_command.
2706 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2708 Permit symbols to be superseded when new symbol files have
2709 been read in, particularly for VxWorks.
2711 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
2712 to the main file, as well as to include files. Also, put global
2713 functions into the global psymtab, to make "i fun" work.
2714 (end_psymtab): Free named symtabs and psymtabs for a file, once a
2715 new psymtab for it has been read.
2716 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
2717 a file, once a new symtab has been read for it.
2718 * mipsread.c: FIXME. We need to do the same for MIPS, but it
2719 looks harder to determine the top-level block before it's been
2720 queued to the psymtab list.
2722 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
2723 If we have wiped out any old symbol tables, clean up at end of
2725 (symbol_file_command): Don't reference symfile_fns if it's zero.
2727 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
2728 defines for the blocks of a blockvector that contain global and
2729 file-static symbols and the first of the smaller scope contours.
2730 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
2731 decode_line_1, make_symbol_completion_list): Use the above.
2732 * coffread.c (end_symtab, patch_opaque_types): Ditto.
2733 * dbxread.c (end_symtab): Ditto.
2734 * expread.y (block): Ditto.
2735 * mipsread.c (throughout): Ditto.
2736 * symmisc.c (free_named_symtabs): Ditto.
2738 * symtab.c (list_symbols): Process the first symbol of the
2739 static psymbols list.
2740 (types_info): Restore this function from its untimely #if 0.
2741 It's not perfect, but it is better than nothing.
2742 (_initialize_symtab): Restore "info types".
2744 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2746 * m68k-stub.c: Remote stub for 680x0's, created from
2747 rem-m68k.shar (which is removed).
2748 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
2749 Remove RCS log stuff now that we use CVS and it blows our diffs.
2751 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2753 * symmisc.c (free_named_symtab): Make it work, in its current
2754 kludgy fashion. Change result to indicate if we blew away bkpts.
2755 * dbxread.c (end_symtab): Accumulate result from
2756 free_named_symtab and print warning if we blew user's state.
2757 * symfile.h: free_named_symtab now returns an int.
2759 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
2761 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
2762 is the first symbol read, even if not mainline.
2763 (dbx_psymtab_to_symtab): symfile might be zero, cope.
2764 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
2765 (set_section_command): New command ("section xxx yyy" -- should
2766 be renamed to "set section xxx yyy" FIXME) which sets the
2767 base address of a section of the exec file, overriding the
2768 virtual address that BFD reports.
2770 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2772 * exec.c: Add add_syms_addr_command to exec_ops, so you can
2773 load symbols at any address while examining an exec file.
2775 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2777 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
2778 for printing the float info is host-dependent, not
2779 target-dependent. FIXME.
2780 * i386-pinsn.c: Move #includes to top, remove useless ones.
2781 * i386-tdep.c: Don't bother including <.../reg.h> since we
2782 don't use it (and it doesn't exist on host systems).
2784 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
2785 Convert negative numbers properly.
2786 (ieee_test): Make numbers really random; fix format arg.
2788 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
2789 * core.c (core_detach): Unpush core_ops, which might not be on
2790 top. We used to just pop the top, which broke things. Don't
2791 need dont_repeat() any more.
2792 (core_file_command): Psst! Don't repeat it.
2793 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
2794 * expprint.c (print_subexp): Avoid switch fallthru on
2795 BINOP_ASSIGN_MODIFY, so we can print += and such.
2796 * frame.h: Fix typo.
2797 * inflow.c (kill_command): After killing inferior, print our
2798 current frame in the core file, if we have one.
2799 (generic_mourn_inferior): When inferior dies, either select
2800 the current frame (in the new target, e.g. core file), or
2801 set both the current and selected frames to NULL.
2803 Changes from Peter Schauer.
2805 * infptrace.c: Avoid <sys/ptrace.h> on USG.
2807 * Make all file names fit in 14 characters (sigh and damn!):
2808 mv hp300hpux-xdep.c hp300ux-xdep.c
2809 mv symmetry-xdep.c symm-xdep.c
2810 mv symmetry-tdep.c symm-tdep.c
2811 mv convex-opcode.h convx-opcode.h
2812 mv tm-vxworks960.h tm-vx960.h
2813 mv tm-vxworks68.h tm-vx68.h
2814 mv Makefile.srcdir Makefile.sdir
2815 mv gdb-int.texinfo gdbint.texinfo
2816 mv remote-sa.m68k.shar rem-m68k.shar
2817 mv remote-multi.shar rem-multi.shar
2818 * Makefile.dist, README, config.gdb, convex-pinsn.c,
2819 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
2820 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
2823 * command.c (user_info_1, user_info): New command for listing
2824 the user-defined commands.
2826 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2828 * dbxread.c (really_free_pendings): Clear file_symbols
2829 and global_symbols after freeing them; otherwise, running
2830 this function twice (if it appears twice on the cleanup
2831 chain), we try to free things twice.
2833 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
2834 based on text_addr (the address of text in core), not on addr (the
2835 offset between text in the .o file and in core). This change
2836 is from Peter Schauer.
2838 * main.c: Define ALL_CLEANUPS as a cast of zero.
2839 (return_to_top_level): Use it.
2840 (main): Do all cleanups after each command run as part
2841 of the gdb startup sequence. Also do all cleanups before
2842 entering the command loop, and every time we exit the command
2843 loop and reenter. Before, the cleanups from the startup sequence
2844 were being left undone until the first error!
2845 (command_loop): Rename do_nothing cleanup to command_loop_marker
2846 so we can see it easily when examining the cleanup chain.
2847 (init_signals): Add another do_nothing for signal handling.
2848 (quit_command): Only try to kill target if it has execution.
2849 Problems in the target stack got us into a state where
2850 inferior_pid was nonzero but none of the targets had execution.
2851 In this state you couldn't exit gdb.
2853 * dbxread.c: Two changes from Peter Schauer.
2854 (echo_command): Fflush output after an echo command.
2855 (show_history): Pass all args to cmd_show_list.
2857 * utils.c (init_malloc): Call mtrace to turn on tracing
2858 if the environment variable MALLOC_TRACE is set to a file name.
2859 * mtrace.c: Add source file which provides a log of every malloc,
2860 free, and realloc to a trace file.
2861 * mtrace.awk: Add source file which analyzes the trace file.
2862 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
2863 (VERSION): Roll to 3.94.3.
2865 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
2866 (check_duplicates): Don't bother with watchpoints.
2867 (set_raw_breakpoint): Comment about danger of this routine.
2868 (watch_command): Parse and eval all args before calling
2871 * solib.c (find_solib): Avoid error in referencing memory to
2872 see if any more shared libraries have been added. This is
2873 particularly useful if the target has terminated. Bug reported
2876 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
2877 in bringing up 3.94.2 on the Sun-3.
2879 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
2880 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
2881 expression (in scope) before reenabling watchpoint.
2882 * signame.c (init_sigs): Add missing declaration of i, fix
2883 sys_siglist declaration.
2884 * source.c (list_command): Fixed range computation to use
2886 * stack.c (backtrace_command): Do not allow command if target has
2887 no stack, print informative error message.
2888 * target.c (target_command): Do not write into command line
2889 because this fails if the target command is used in a user defined
2890 command. [This change was enhanced by gnu to support any-
2891 unique-prefix matching on target names.]
2892 * valops.c (value_struct_elt): Avoid infinite loop on an
2893 erroneous attempt to print the member of function (try p main.p).
2895 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2897 * expread.y (name_no_typename): Avoid reduce/reduce errors
2898 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
2899 Since the GDB parser really doesn't use name_no_typename in a
2900 name-only context, the parser can't tell the diff between
2901 names and numbers here. Avoid allowing a name_no_typename
2902 to be a NAME_OR_*INT to resolve the conflict.
2904 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2906 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
2908 * valprint.c (val_print_fields): bitfield printing didn't handle
2909 byte order. Indirect through a few more fns to cope.
2911 * values.c (modify_field): also cope with byte order.
2913 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2915 Cleanup for release 3.94.2:
2917 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
2918 include files. Roll version to 3.94.2.
2920 * coffread.c (init_stringtab): Read length into unsigned char
2921 array before swapping; don't assume 32-bit longs.
2923 * target.c (target_info): Don't bother with get_sym_file, just use
2924 the symfile global variable.
2925 * symtab.h, symfile.c (get_sym_file): Delete it.
2927 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
2928 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
2929 (read_type): Replace one more error() with complain().
2931 * mipsread.c (parse_partial_symbols): Replace printf with complain.
2933 * i960-tdep.c: Fix copyright attribution.
2935 * config.gdb: Quote all backquotes in doublequotes. You can
2936 quote me on that. BSD 4.4 shell found this one.
2938 * infptrace.c (throughout): The third argument to ptrace is an
2941 * infrun.c (wait_for_inferior): When program has terminated, we
2942 have to call target_terminal_ours before we pop that target off
2943 the stack (e.g. before a call to target_kill or
2944 target_mourn_inferior). This fixes problem where a program
2945 terminates, then GDB stops for (tty output) and you have to type
2946 "fg" to the shell to resume it. FIXME: This code for what to
2947 do after termination really should be in normal_stop instead.
2949 * gdbcore.h (read_memory_check): Change declaration; it changed
2952 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
2953 4.4 prereleases, this avoids a bug in their sgtty compatability
2955 * remote.c: Use terminal.h rather than hand-rolling the same.
2957 * signame.c, signame.h (psignal): Arg is unsigned, not int.
2958 * utils.c (strsave, strstr): Fix arg types.
2959 * valprint.c (val_print): lint
2961 MIPS symbol table support from Per Bothner:
2963 * symfile.c (symtab_fns): Remove initializer table that needs to
2964 be hacked for each new symbol file format supported.
2965 (add_symtab_fns): New function, chains symbol table
2966 handlers into the global list.
2967 (symfile_init): Search this list.
2968 * symfile.h: Add next pointer, declare add_symtab_fns.
2969 * coffread.c (_initialize_coffread): Call add_symtab_fns.
2970 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
2972 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
2973 symbol *). Thus, we no longer need the hack to trash
2974 pst->filename. Good, since that hack confused code in symfile.c!
2976 (reorder_symtabs, destroy_all_symtabs): Removed static
2977 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
2978 Instead, the latter now uses a temporary array (stack-allocated
2979 from an obstack, and then freed).
2981 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
2982 haven't been set in the outermost stBlock of a procedure. This was
2983 a problem with f77 binaries on Ultrix 4.?.
2985 (new_symtab, new_symbol, new_type): Continue changing code to use
2986 obstacks more and otherwise conform to dbxread internal style.
2987 Made the free_code of symtabs be free_linetable (as in dbxread)
2988 instead of free_contents. This implies memory leaks when reading
2989 a new symbol table, until the conversion is finished. Did change
2990 (struct symbol) and (struct type) to be allocated on the
2991 symbol_obstack. Blocks and blockvectors are among the things
2994 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
2995 tested much, but it solved one problem (reported by Meissner), and
2996 cleans up some other things. The problem happened when an
2997 included file contains actual code (functions) and not just
2998 definitions. The mips coff is a little inconvenient there, since
2999 it may cause a procedure to be mapped to the wrong psymtab.
3001 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3002 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3003 this will need work for the new core paradigm.
3005 Opcode patches from the net:
3007 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3008 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3009 missing altogether - they are added here. From Bruce Bauman.
3010 * mips-opcode.h: The low mask for C0 instructions was too small.
3011 From Garrett Lau. I modified the fix to check the entire 32-bit
3014 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3017 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3019 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3021 * dbxread.c (read_type): Pointer subtraction (value_sub in
3022 valarith.c) sometimes failed because the types of the
3023 pointers being subtracted were not identical.
3024 These differed because dbxread.c was allocating pointer types
3025 using dbx_alloc_type+smash_to_pointer_type instead of
3026 lookup_pointer_type. I failed to find a justification for the
3027 former, so I changed it to use the latter. Similarly, I
3028 replaced smash_to_function_type by lookup_function_type,
3029 and smash_to_reference_type by lookup_reference_type.
3031 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3032 _initialize_mipsread): corresponding changes.
3034 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3036 * source.c (mod_path): Do tilde_expand on each component of the path,
3037 rather than on the (list of) paths as a whole.
3038 (print_source_lines): Set first_line_listed in addition to
3039 current_source_symtab and current_source_line. If the source was
3040 not findable, after a "dir" command to fix the problem,
3041 a "list" would get the wrong lines.
3043 While I was there... (gnu):
3045 * dbxread.c (read_type): Change error to complaint.
3047 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3049 First attempt at detailed understanding of symbol table memory alloc.
3051 * dbxread.c (dbx_symfile_read): Free our string table if we
3052 aren't the mainline. Free the "info" struct since we're done with
3054 (init_psymbol_list): Free any previously allocated psymbol lists.
3055 (): FIXME: Should realloc-down the psymbol lists when done reading
3056 the main symbol file?
3058 * symmisc.c (free_symtab): Free fullname field too.
3060 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3061 (REGISTER_ADDR): Make result type unsigned int.
3063 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3064 define REGEX must also define REGEX1 (its dependency).
3066 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3068 * tconfig/i960: No longer works, points you at vxworks960 or
3071 * xgdb.c, XGDB-README: Remove file. Users can get the much
3073 * Makefile.dist: Remove all trace of xgdb.
3075 * breakpoint.c (breakpoint_1): Pass demangle arg to
3076 print_address_symbolic.
3077 (clear_breakpoints): Remove unused function.
3078 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3079 (breakpoint_re_set): Use catch_errors to do them all anyway.
3081 * gdb-int.texinfo (Host versus Target): Add section on what is
3082 a "host" feature versus what is a "target" feature.
3084 * infcmd.c (path_command, path_info): Handle the PATH variable
3085 (object search path) as conveniently as the source search path.
3086 * environ.c (set_in_environ): Set some vars in GDB's environment,
3087 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3088 * source.c (mod_path): New function, from guts of
3089 directory_command, modifies a path. Used by path_command.
3090 (directory_command): Call it.
3091 * defs.h (strsave): Declare.
3093 * utils.c (sevenbit_strings): Add new printing option.
3094 (printchar): Use it.
3095 (strsave): Provide this handy helper routine.
3096 (set_width_command): Rename set_screen_width_command.
3097 (_initialize_utils): "set screen-width" => "set width";
3098 "set screen-height" => "set height"; add sevenbit-strings.
3100 * infcmd.c (do_registers_info): Print floating point registers
3101 in raw hex as well as float format, regardless of whether it is
3102 a "virtual" convertible register.
3103 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3104 regs as a double, just in case it's being used that way.
3105 * values.c (unpack_long): Comment on array/function coercion.
3106 (unpack_double): Argument is in target byte order now. For
3107 integer arguments, just call unpack_long and float the result.
3108 * m68k-tdep.c: include defs.h for "const" handling.
3109 * remote-nindy.c: Use ieee-float stuff.
3110 (nindy_fetch_registers): Unpack double regs to host double, then
3112 (nindy_store_registers): Pack extendeds to host double, flip
3113 around by misusing unpack_double, send as target double.
3115 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3116 zero, as when stopped at the first instruction of a process.
3118 * blockframe.c: Fix filename in comment (param.h => tm.h).
3119 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3120 * tm-68k.h: Fix typos.
3122 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3124 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3126 * coredep.c (fetch_core_registers): Pass end-address of register
3127 section to register_addr as expected. Don't call supply_register
3128 if we'd just pass it garbage.
3130 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3132 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3134 * target.c (push_target, target_info): Cast enums to int for < or
3137 * stack.c (print_frame_info): Identify source file & line
3138 even if we can't print it.
3140 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3142 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3144 Clean up IEEE floating point support.
3146 * ieee-float.h: New file.
3147 * ieee-float.c: Write real routines to convert between host
3148 doubles and various target IEEE extendeds.
3149 * m68k-xdep.c: Eliminate assembler code for extended floats.
3150 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
3151 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3152 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3153 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3154 double_to_ieee_extended.
3155 * i960-tdep.c: Define ext_format_i960.
3156 * m68k-tdep.c: Define ext_format_68881.
3157 * sparc-tdep.c: Define ext_format_sparc, though unused.
3158 * Makefile.dist (HFILES): Add ieee-float.h.
3159 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3162 Obsolete the "coffstrip" program in favor of using BFD's strip.
3164 * nindy-share/coffstrip.c: Remove file.
3165 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3166 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3167 * tconfig/nindy960: Remove reference to coffstrip.o.
3169 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3171 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3173 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3174 * dbxread.c: Remove static symfile_bfd.
3175 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3177 * inftarg.c (child_detach): Pop the child_ops vector if the
3178 detach is successful.
3179 * remote-nindy.c (nindy_create_inferior): Don't push a new
3180 nindy_ops since nindy uses the same one for execution and memory
3182 * core.c (core_ops): Use child_attach and child_create_inferior
3183 rather than default attach and create_inferior functions.
3185 Handle floating point registers in core files.
3187 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3188 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3189 This version untested since BFD doesn't yet support sun3 core
3191 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3192 conventions. Fix comments and style. This version has not
3193 been compiled yet, since we have no HP inhouse.
3194 * core.c (get_core_registers): Look for two sections, ".reg"
3195 and ".reg2", and pass both to fetch_core_registers sequentially.
3197 Revise directory path yet again.
3199 * source.c (forget_cached_source_info): Not static any more.
3200 (init_source_path): New default source path is "$cdir:$cwd".
3201 (dir_command): Handle variable arguments ($cdir, $cwd).
3202 (source_info): Print "Compilation directory" rather than
3203 "Originally compiled in" to remind people of $cdir.
3204 (openp): If the path contains $cwd, use current directory.
3205 (open_source_file): If compilation directory is known, replace
3206 first $cdir in path with the compilation directory.
3207 (print_source_lines): Even if we can't print the lines, set the
3208 current symtab and line for future commands like "info source" or
3209 "breakpoint". Also, error message now contains the file name,
3210 line number, and file access error message.
3211 (_initialize_source): Fix help text to describe changes.
3212 * main.c (cd_command): Forget cached source info when we chdir.
3213 * utils.c (strstr): Add simple implementation.
3215 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3217 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3218 Byte-swap COFF symbol tables if necessary when reading them in.
3219 Use complain() to replace error message in one spot. Needs
3220 corresponding change in bfd/coff-code.h to make some symbol
3221 swapping routines non-static.
3223 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3225 Merge changes from Eirik Fuller, for UTek.
3227 * defs.h (errno): Add declaration.
3228 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
3229 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3230 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3231 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
3232 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
3233 declarations of errno.
3235 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3237 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3238 <rpc/rpc.h> and <rpc/types.h>.
3240 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3242 * i960-tdep.c (examine_prologue): Add new argument limit,
3243 which stops the scan at the end of the prologue, or at the PC.
3244 This fixes a problem where it walks down into the code for the
3245 user's statements if that code looks like function prologues.
3246 Mark Fox and I have been bouncing this code back and forth, making
3247 small changes to it. Callers changed to match.
3249 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3251 Cleanup for gdb-3.94 release final:
3253 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3254 the .c files from vx-share and nindy-share, from the various
3255 macros, since they are not found via ALLDEPFILES.
3256 (SFILES): Add tm-i960.h.
3257 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3258 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3260 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3261 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
3263 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
3265 * am29k-tdep.c: Add contribution line.
3266 (examine_prologue): Cache information about function prologues in
3267 the misc-function-vector to avoid lots of references over the
3268 serial line while examining instructions.
3270 * core.c (core_close): New function made from cleanup_core.
3272 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3273 remote-vx.c, remote.c, target.c, target.h,
3274 Update target_ops vector to add attach, close, and load entries.
3275 Use add_syms_addr_command, not add_file_addr_command, for
3276 add_file. Break out close routine from existing code.
3278 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3279 they are in an obstack.
3280 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3282 (define_symbol): Add symbol type parameter; change callers;
3283 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3284 it to influence the symbol class on the i960.
3285 (define_symbol): Swap LOC_CONST's into target byte order.
3287 * exec.c (exec_close): New function.
3288 (exec_file_command): Call it.
3290 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3291 Fix byte order of frame pointer.
3292 (read_var_value): Result of 0 if var's value can't be found,
3293 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3294 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3295 (locate_var_value): Use read_var_value and use its lazy address
3296 as the location of the var's value. Lint.
3298 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3301 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3302 obsolete Intel versions in favor of vxgdb versions.
3303 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3304 code dealing with byte order of values, which Intel did in host byte
3305 order rather than gdb-4's target byte order.
3306 (i960_frame_chain_valid): Move to nindy-tdep.c.
3307 (examine_prologue, skip_prologue, frame_find_saved_regs,
3308 frame_args_address, leafproc_return, saved_pc_after_call,
3309 pop_frame): Add vxgdb versions from Mark Fox.
3310 (examine_prologue, frame_struct_result_address): Add code
3311 to deal with the saved value of G13 (struct return address
3313 (frame_args_address): Modify Mark's version to prefer the
3314 saved value over the current value in the topmost frame.
3315 Cache result in the frame info to avoid performance hair in
3317 (print_fault): Add gdb960 code for printing faults.
3318 (_initialize_i960): Actually call check_host.
3320 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3321 add stub routines. FIXME, these currently just return zero!
3323 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3324 (attach_command): Call target_attach, not target_open, now.
3326 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3327 (child_attach): Rename from child_open.
3328 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3329 don't confuse it with a zero step_resume_break_address.
3331 * inftarg.c (child_detach): Eliminate inferior_pid test.
3332 (child_files_info): Clean up message a bit.
3333 (child_ops): Use child_attach, not child_open, to attach.
3335 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3336 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3337 findvar.c to here, since it depends on the contents of the
3338 shadow_contents of breakpoints, but keep if #if 0 since it is
3341 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3344 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3345 (ptype_command, display_command): Eliminate have_inferior_p and
3346 have_core_file_p in favor of target_has_stack or
3347 target_has_execution.
3348 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3349 code for actually finding the values of arguments, though we still
3350 keep track of the maximum stack offset for use in printing unnamed
3351 arguments. Handle missing FRAME_ARGS_ADDRESS.
3353 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3354 (struct nindy_regs): Define registers passed to/from nindy.
3355 (nindy_fetch_registers, nindy_store-registers): Translate between
3356 nindy and GDB formats for the registers.
3357 (dcache_init): Statically allocate the cache, since it was being
3358 allocated by a malloc that was never freed anyway.
3359 (nindy_create_inferior): Error, not core dump, if no exec file.
3360 (nindy_before_main_loop): Use target_load, not target_add_file.
3362 * remote-vx.c (net_load): Specify large timeout for load
3363 requests. Allow user to break out with INTERRUPT.
3364 (net_break): Remove useless code, clean up. Change callers.
3365 (parse-args, skip_white_space, find_white_space): Clean up arg
3366 parsing to cope with quoted strings.
3367 (net_wait, net_quit): Never call error, just return status.
3368 (vx_read_register, vx_write_register): Cleanup status checking.
3369 #ifdef the code based on which CPU we are using (960 or 68k),
3370 FIXME, this should be completely general but it isn't yet.
3371 (vx_xfer_memory, vx_resume): Cleanup status checking.
3372 (vx_run_files_info): Improve message.
3373 (vx_load_command): Renamed from vx_add_file_command. Allow load
3375 (net_ptrace): Remove unused routine.
3376 (vx_wait): Adopt code from vxgdb960 to cope with broken
3377 connections to target machine and prompt to disconnect. Remove
3378 debug printouts. Map some EVENT_'s to SIGnals.
3379 (add_symbol_stub, vx_open): Print names of object files we found,
3380 and "ok" if we read their symbols OK. Clarify output in general.
3381 (vx_attach, vx_detach, vx_kill): Add these commands.
3382 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3383 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3384 "info files" output, and create_inferior, since we already have
3387 * stack.c (frame_info): Replace Frame_unknown with 0.
3388 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3389 (return_command): Pop until the PC matches as well as the FP,
3390 so it works even if the FP is shared with another function,
3391 as in "frameless" or "leaf" procedures.
3393 * symfile.c (load_command): renamed from add_file_target_command.
3394 (add_syms_addr_command): renamed from add_file_addr_command.
3395 (add_syms_command): Stub to call target_add_syms.
3396 (_initialize_symfile): Change command names and descriptions,
3397 add-file => add-syms, and load from alias to its own command.
3399 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3400 maybe_kill_then_create_inferior): Default for attempts to start
3401 a process, if one is already running, is to ask about killing
3402 it and retry if yes.
3403 (upstack_create_inferior): #if-0 it, strata obsolete it.
3404 (push_target, unpush_target, pop_target): to_close() a target
3405 before unstacking it.
3406 (target_info): Renamed from target_files_info.
3407 (_initialize_targets): Rename "i files" as "i target", accessible
3410 * target.h: Improve comments about the target_ vectored routines.
3412 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3413 Convert commenting style to standard GNU style.
3414 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3415 (SKIP_PROLOGUE): No longer a no-op.
3416 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3417 (*_REGNUM): Sort register numbers.
3418 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3419 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3420 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3421 are now 10 byte extendeds, not 8 byte doubles.
3422 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3423 for nindy versus vxworks targets. FIXME, this should possibly go
3424 in the target vector.
3425 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3426 frame_saved_regs and arg pointer with each frame.
3427 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3428 (FRAME_ARGS_ADDRESS): Use cached result.
3429 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3430 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3431 (PRINT_RAMDON_SIGNAL): Call print_fault.
3432 (POP_FRAME): Now works.
3434 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3435 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3436 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3437 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3440 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3441 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3443 * valarith.c (value_subscripted_rvalue): Avoid handling
3444 floats and doubles specially; it gave alignment errors. Lint.
3446 * valops.c (value_of_variable, value_of_this): Error if unknown
3449 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3450 to avoid alignment problems.
3451 (value_print): Handle unknown value address.
3452 (cplus_val_print): Two args are ignored; remove them. Change caller.
3453 (val_print): Use unpack_long rather than pointer-deref.
3456 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3457 to avoid alignment problems.
3458 (value_being_returned): Error if return value unknown.
3459 (set_return_value): Add bogosity warning, FIXME. *
3461 * TODO: A woman's work is never done.
3463 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3464 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3465 Add ieee-float.o to OBS.
3466 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3467 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3468 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3470 Changes to generalize the VxWorks RPC protocol slightly, to handle
3471 i960 as well as 68000.
3473 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3474 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3475 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3476 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3477 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3478 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3479 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3480 so they will move in target byte order rather than network
3481 byte order (happens to be the same).
3483 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3485 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3487 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3490 Add contribution lines to various files, showing where they
3493 * breakpoint.c (break_insn, check_break_insn_size,
3494 read_memory_nobpt): Remove to mem-break.c.
3496 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3499 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3500 entry has bad register number. This change is not
3501 tested in this release, FIXME.
3503 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3506 * value.h: Force value's contents field to be aligned to hold
3507 at least a double or a long long (if supported). This avoids
3508 doing bcopy's in and out of the contents field.
3510 (step_1): Avoid coredump under obscure circumstances when we
3513 * symtab.h (misc_info): Add field to misc function vector for
3514 any kind of cached information the target code desires. AMD
3515 29000 uses this to avoid repeating examine_function_prologue's.
3517 * coffread.c: Lint. Remove static symfile, read_section_header.
3518 core.c (have_core_file_p): Lint: remove.
3519 expprint.c (print_subexp): Lint.
3520 infptrace.c, valops.c, valprint.c: lint.
3522 Roll in changes from vxgdb-5.0.1:
3524 * symtab.h: Comment byte order of each address class. Add
3525 LOC_LOCAL_ARG for frame-relative args (960).
3526 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3527 symtab.c, symmisc.c: ditto.
3529 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3531 * remote.c (remote_resume): Error if resume with a signal.
3533 * symfile.c (prim_record_misc_function): Clear misc_info.
3534 (fill_in_vptr_fieldno): Check stub type of arg.
3536 * valops.c (value_cast): Avoid looking up names of types whose
3537 name we don't know, to prevent coredump. Sun CC produces typedef
3538 rtx and the name of *rtx is zero...
3540 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3542 Roll in changes from final AMD 29000 port (Tiemann).
3544 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3545 for ../include/a.out.encap.h. This might not work now that BFD
3546 is separately compiled. Instead, BFD support for encap will have
3547 to translate machine type 29k into the right COFF_MAGIC.
3549 * infcmd.c: Remove references to inferior_pid that aren't used
3550 in actual ptrace calls; use target_has_execution, etc.
3551 (have_inferior_p): Remove function.
3552 (program_info): Print target info rather than "process number";
3553 avoid gratuitous messages unless from_tty.
3554 (run_stack_dummy, finish_command): Set proceed_to_finish.
3555 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3556 main.c: Lint. Lose have_inferior_p().
3557 inferior.h (have_inferior_p): Remove, lint.
3558 (proceed_to_finish): Add flag to ask that all regs be saved
3559 by normal_stop, for the few commands that need it, speeding up
3560 serial I/O. Add comments to stop_registers.
3562 * remote-eb.c: Remove newline from breakpoint message we grep
3563 for. Never time out when running the user program.
3567 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3569 Roll in changes from vxgdb-5.0.1:
3571 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3572 symbol in its raw form, we are processing an unlinked ".o" file.
3573 See if the target environment has assigned it an address, using
3574 target_lookup_symbol (VxWorks does), and enter it into the symtab
3577 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3578 68k versions for a simpler version that assumes zero FP at bottom.
3579 Fixes bug of truncated stack reports.
3581 * target.h (target_lookup_symbol): Define this routine's args
3582 and result, finally.
3584 * target.c (nosymbol): Default routine for target_lookup_symbol.
3585 (target_default): Default lookup_symbol and call_function too.
3586 (files_info): Only print has_all_memory warning if a non-dummy
3589 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3590 vx_convert_from_virtual): If target does not have floating point,
3591 zero register "values", and avoid doing cross-net conversions.
3592 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3593 (vx_open): Rearrange code that attaches to target and reads
3594 symbols for all loaded modules, to work if some of the modules
3595 are not accessible. Add symbol_stub() and add_symbol_stub()
3596 as callbacks from catch_errors(). Allow connect attempt to be
3597 interrupted painlessly with ^C (FIXME, there are still some bugs
3598 if the interrupt happens during symbol reading.). Print
3599 final message with puts_filtered, since symbol messages are
3604 * main.c (catch_errors): Only print errstring if non-null.
3605 (command_loop): Avoid an ioctl per command to test ISATTY.
3607 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3608 (vx_xfer_memory): Return correct result!
3609 (vx_files_info): Indicate whether target has float or not.
3610 (vx_lookup_symbol): Complain, not error, if target gone.
3611 (vx_open): Print "Connected" msg before disabling immediate-quit.
3612 [FIXME: lookup_symbol and vx_open changes need testing.]
3614 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3615 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3616 contributor lines and update copyrights to 1991.
3618 Changes from an attempted H-PUX host port:
3620 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3621 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3622 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3623 * remote-vx.c: include <sys/time.h> for HPUX.
3624 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3625 "core_file_command" routine to BFD regime. May not work yet.
3627 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3629 * xgdb.c: Replace X10 version with some VJ version.
3630 (FIXME: Its copyright assignment is not on record.)
3631 * xgdb.c: Update include files to X11R4 (Xaw crud).
3632 (xgdb_display_source, create_text_widget): fix call to
3633 get_filename_and_charpos. Rewack source window stuff for X11R4
3634 (gleaned from include files, and "nm's" of binary libraries, since
3635 I had no doc available).
3636 (append_selection, append_selection_word): Disable with FIXME
3637 since R4 changed interface here.
3638 (create_buttons): Add back the old set of buttons.
3639 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3641 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3642 Roll VERSION to 3.94 (not yet final though).
3644 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3646 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3647 obstack_int_grow, obstack_int_grow_fast): Eliminate
3648 cast on left of assignment, which gives MIPS cc fits and is
3651 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3652 F_ALIAS. Use printf, not fprintf, when not passing a file
3654 (compare_opcodes): Check that identical instructions have
3655 identical opcodes, complain otherwise.
3657 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3658 was reported by Roland McGrath.
3659 (unimp): Only match if exactly zero instruction. (Roland)
3660 (branches and traps): Generate all variations of these
3661 instructions with macros, based on a single call that defines
3662 each condition name and its binary representation.
3663 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3665 * valprint.c (val_print_fields): Take, and use, format parameter.
3666 This means that "p/x struct" again prints the elements in the
3667 desired format. Changed callers.
3669 * stack.c (frame_info): Use filtered output, and indicate wrap
3670 points. Remove kludgy formatting designed to avoid line wrap.
3672 * utils.c (wrap_here): If the line is already full (because
3673 we had printed a long indent or long wrapped string), do an
3674 immediate newline-and-indent.
3676 * m68k-pinsn.c (print_insn_arg): Bugfix from
3677 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3678 instruction is incorrectly disassembled as bkpt #8.
3680 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3681 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3682 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3683 and then will dump core (sometimes). I traced it back to an
3684 uninitialized symfile_name in psymtab_to_symtab.
3685 (const_vol_complaint): Add quotes to message.
3686 (define_symbol): Only believe line number if gcc_compiled.
3687 Avoid allocating symbol if we will not return it.
3689 Add target strata support so that newly established targets go
3690 into their right place in the target stack (e.g. a new exec file
3691 doesn't wipe out the ability to access the running process).
3693 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3694 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3695 and initialize it properly in all the targets.
3697 * target.h: Document strata. Change return type of push_target.
3699 * target.c (nomemory): new function for dummy memory access.
3700 (tcomplain): Rename complain, now also used in symfile.c.
3701 (push_target): Push targets within strata. New return value shows
3702 whether new target is on top of stack or not. Always keep dummy
3704 (target_files_info): Ignore dummy target.
3706 * core.c (core_open): Warn user, and skip accessing file, if the
3707 core target is not the topmost target in the stack.
3708 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3711 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3712 target_ops, it doesn't belong there since we have no regs there.
3713 Change name of target from machine => memory to clarify.
3715 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3717 * Freeze version 3.93 for release.
3719 * Makefile.dist: Handle vx-share and nindy-share subdirs
3720 properly when building gdb.tar.Z.
3722 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3723 printed in various places, so I could change just one copy.
3725 * dbxread.c, coffread.c: Change references to bfd->iostream
3726 to cast to FILE *, now that BFD avoids needing types defined
3727 in other header files.
3729 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3731 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3732 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3733 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3734 (actually gcc -Wall).
3736 * dbxread.c: Remove first_global_sym, last_global_sym, since
3737 they are never referenced.
3739 * defs.h (baud_rate): Declare.
3740 main.c: Define it, and add the -b option to set it.
3742 * gdb-int.texinfo: Add text on how to define a new host or target
3743 architecture, prompted by Per Bothner's questions about MIPS
3746 * gdb.texinfo: Document "complaints". Change doc of -q since
3747 gdb no longer prints the copyright and blurb if you specify a file
3748 name to be debugged (just like Emacs). Add doc for Nindy-specific
3749 command line flags for specifying target serial port and such.
3750 Update copyright to 1991.
3752 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3753 has taken over for us the job of ripping up executable files. The
3754 crud caused Per Bothner's port to not compile.
3756 * infrun.c (normal_stop): Avoid printing "Program exited
3757 normally" if we are in batch mode. This allows a GDB which
3758 executes a program on a target system, to behave like a Unix
3759 command (input from stdin, output to stdout, no extraneous
3762 * main.c (main): Allow additional machine-dependent command line
3763 options to be specified with the ADDITIONAL_OPTIONS,
3764 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3765 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3766 processing to occur just before the main loop with
3767 BEFORE_MAIN_LOOP_HOOK.
3768 (main): If a "core file" argument is specified, and it is not a
3769 core file, try it as a process ID to attach.
3770 (symbol_completion_function): Attempt to cope with
3771 "show screen-" TAB, not very successfully. This needs more work,
3773 (batch_file): New function, returns whether we are reading
3774 commands from an interactive tty on stdin, or from somewhere else.
3775 Called by normal_stop since it doesn't get from_tty passed down
3776 to it like many commands do.
3778 * remote-nindy.c: Handle command line options for nindy
3780 (nindy_before_main_loop): Prompt user for tty name if they
3781 don't specify it before getting to the interactive command loop.
3783 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3784 and -r command line options. Also add hook before main loop
3785 to make it easy to specify a tty.
3787 * TODO: More things to do, one done.
3789 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3791 * dbxread.c: Make complaint() calls pass pointer, not struct.
3792 Add complaints about badly formatted C++ type information
3793 (const/volatile indicator, and parse errors resulting in
3794 error_type). Fix C++ virtual member fn comment.
3795 (read_struct_type): Avoid bumping pointer if we got a parse
3796 error; this prevents our walking beyond the end of a string.
3797 Terminate loop on null char as well as semicolon.
3798 (process_one_symbol): Fix the LBRAC fix so that it uses the
3799 last previous SLINE, FUN, or SO record's PC address. C++ debug
3800 symbols did not have SLINE records in a useful order compared
3801 to the LBRAC records.
3802 (define_symbol): Handle "catch" records.
3804 * symtab.c (check_stub_type): Added new complain
3805 `stub_noname_complain' and added a consistency check to
3806 keep the debugger from crashing when finishing from an
3807 exception frame. A real fix will be needed later.
3809 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3811 * infcmd.c (attach_command): Make global.
3813 * Makefile.dist (REMOTE_OBS): Make these compile by default,
3814 but make them easy to comment out. Perhaps later they should
3815 be enabled by what CPU you configure for? FIXME.
3816 (VERSION): Roll to 3.93.
3817 (pinsn.o): Remove rule for obsolete file.
3818 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
3820 Run down a problem that manifested by printing the wrong function
3821 name in stack traces of read_ofile_symtab. Turned out that the
3822 problem was the SunOS 4.1.1 (and previous) C compiler outputs
3823 the LBRAC symbol with an address in the *data* segment, which
3824 blew our binary search through the blocks.
3826 * dbxread.c: Use the complain() facility consistently to bitch
3827 about problems in the symbol file we are reading.
3828 (finish_block): Add code to check the nesting of the blocks;
3829 complain and Procrust them to fit if wrong.
3830 (make_blockvector): Check the order of the blocks, complain
3831 [but don't cope] if wrong.
3832 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
3833 symbols to be sure their PC value is greater than the last SLINE
3834 (line number) symbol we've seen, complaining and adopting the
3835 SLINE PC value if wrong.
3837 * symfile.h (struct complaint, complaint_root, complain,
3838 clear_complaints): Add.
3839 * symfile.c (complain, complaint_root, clear_complaints): Add
3840 facility to deal with non-fatal complaints and to regularize their
3842 (symbol_file_add): Clear complaint counters to allow new complaints.
3843 (initialize_symfile): Add 'set complaints' and 'show complaints'.
3845 * dbxread.c (dbx_symfile_read): Remember the address and size
3846 of the string table for the main symbol file, so we won't read it
3848 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
3849 to avoid reading the string table yet again. Lint.
3850 (throughout): Improve filtered output, including word wrap.
3851 (read_range_type): Improve Bothner's fix to handle other types too.
3853 * utils.c: Improve line wrap implementation. Handle unlimited
3854 width by making chars_per_line unsigned.
3855 (puts_filtered): New, easy, function.
3857 * defs.h (puts_filtered): add.
3859 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
3860 call the identical sort_symtab_syms() in symfile.c instead.
3862 * expread.y: Suggest the `file' command rather than `symbol-file'.
3864 * command.h (enum var_types): Add zinteger for seroable
3866 * command.c (do_setshow_command): Handle var_zinteger. Restructure
3867 nested if's into a switch.
3869 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
3870 we did not stop because of a breakpoint (it must have been for
3871 some other reason, like a "stepi"), so don't print anything.
3873 * symtab.c: Include <sys/types.h> all the time. Now that BFD
3874 doesn't include <sys/types.h>, old SunOS's require it for
3877 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
3879 A test port of gdb-3.92.6 to the Sony NEWS.
3882 Don't normally link in remote- or vx stuff.
3883 Some of it doesn't compile, and it wastes space for 99% of the users.
3884 Remove reference to no-longer-used HAVE_VPRINTF.
3885 Fixed BFD_DEP typo to BFD_DIR.
3887 Fix cast in arg to bfd_h_getlong.
3888 Make char *prefix be const.
3889 Fix how certain range types are mapped into builtin unsigned int types.
3891 Remove 2 #includes. They cause errors (on Sony, at least),
3892 and aren't needed (they wern't in earlier versions).
3894 print_address_symbolic should never demangle labels
3895 (since it prints *assembler-level* labels).
3897 [This was superseded by the change to printcmd below.]
3900 Add some "volatile" return types to avoid warnings.
3901 If MISSING_VPRINTF add vprintf function and not just macro
3902 (since vprintf is used in printcmd.c).
3904 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
3905 (The latter isn't grokked by some PCC-based compilers.)
3907 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
3909 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
3910 * nindy-share/coffstrip.c
3911 Added some forward declarations (otherwise, gcc complains
3912 about implicit extern redefined as static).
3914 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3916 Changes inspired by Per Bothner:
3917 * printcmd.c (print_address_symbolic): Take additional parameter
3918 specifying whether to demangle.
3919 (print_address): Pass in asm_demangle to control demangling.
3920 (print_address_demangle): New fn, takes explicit arg to control
3922 * utils.c: Add new vars demangle and asm_demangle, and let them
3924 (fputs_demangled): If !demangle, just print the argument.
3925 (fprint_symbol): If !demangle, just print raw symbol.
3926 * valprint.c (val_print): Call print_address_demangle rather than
3927 print_address, to cause demangling to depend on the global
3928 rather than assembler-level demangling setting.
3929 * WHATS.NEW, gdb.texinfo: Document.
3931 * main.c (show_command): Show all settings if no arg.
3932 (initialize_main): Make "info set" the same as naked "show".
3933 * command.c (cmd_show_list): Handle prefix commands in the
3934 list, and print the name of the setting as well as its English
3935 description and value.
3937 Allow gdb functions to specify where a line should wrap if it
3938 exceeds the size of a terminal line. Use it to make the output
3940 * utils.c (set_screen_width_command): New fn, mallocs a buffer
3941 of the right size when screen width changes.
3942 (set_screensize_command, screensize_info): Remove #if 0'd fns.
3943 (wrap_here): New fn, indicates a point in the output where we
3944 should wrap the line rather than just letting it overflow at a
3946 (fputs_filtered): Implement wrapping.
3947 (n_spaces): New fn, returns a pointer to N spaces.
3948 (print_spaces_filtered): Use n_spaces.
3949 * defs.h (n_spaces): Declare.
3950 * stack.c (print_frame_info): Wrap with 4-space indent after
3951 fn name and before filename and line number.
3952 * printcmd.c (print_frame_args): Wrap with 4-space indent
3953 before each argument name is printed.
3954 * valprint.c (value_print): Wrap with no indentation before
3956 (val_print_fields): Wrap with indentation relative to nesting
3957 level before each field name.
3958 (val_print): Wrap with nesting indentation before array elements.
3959 * command.c (do_setshow_command): Avoid extra newlines,
3960 wrap with 4-space indent around values printed, end with period.
3961 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
3963 * breakpoint.c (breakpoint_1): Implement addressprint for
3964 "info breakpoints" display. Change file name and line number
3965 format to " at file:nnn" rather than " (file line nnn)".
3966 * gdb.texinfo: Document.
3969 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3971 Frozen for gdb-3.92.6 release.
3973 README, WHATS.NEW: Update for 3.92.6 release.
3975 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
3976 coffread.o from configs since it is now built by default.
3977 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
3978 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
3979 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
3980 from configs since it is now built by default.
3982 Makefile.dist: Update for release 3.92.6. Handle files that
3983 have been moved to ../include, ../getopt, or ../bfd. Add
3984 saber.suppress and tests directory. Add config.status to
3985 the release (it will say "none").
3987 coredep.c: Minor formatting fixes.
3989 These changes were made in early December but only checked in now:
3990 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
3991 nindy-share/nindy.c: lint
3992 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
3993 register values coming back from the target; we store values
3994 in target byte order everywhere.
3996 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
3998 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4000 * valprint.c (cplus_val_print, val_print_fields): New functions,
4001 which print C++ objects. They conspire to avoid printing a
4002 virtual base class more than once, following all the twists and
4003 turns of C++ virtual base rules.
4004 (val_print): Call the above rather than do it by hand.
4006 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4007 symbol file, not for added files like shared libs. This really
4008 needs to be generalized to a timestamp per file.
4010 * core.c (cleanup_core): Avoid coredump if no core file.
4012 * config.gdb: Accept -host or -target in place of +host or
4015 * coffread.c (find_linenos): Avoid desupported BFD interface
4016 to line numbers. We still read them manually rather than using
4017 BFD's "generic" features.
4019 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4021 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4023 * Makefile.dist: Eliminate use of $< in explicit targets.
4025 * readline/Makefile: Use $< rather than $*.c, which does not
4026 include the VPATH in GNU Make.
4028 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4029 copies of tconfig/i960, added for global configuration
4030 compatability. All i960 versions can read both coff and b.out.
4032 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4033 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4036 * TODO: Think of more things to do.
4038 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4040 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4041 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4042 64-bit float conversion.
4044 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4045 equivalent to sun?os4 so global config works.
4047 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4049 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4051 * main.c: Only declare linesize once; declare pagesize not at
4052 all, since it is never used.
4053 (main): Clear newly allocated line before it is used.
4055 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4057 Further stabilization for the Intel 960.
4059 * Makefile.dist: Parameterize the location of the "include"
4060 and "bfd" directories, as well as "getopt". Add symfile.c.
4061 Link in both dbxread and coffread. Fix up "make depend" to
4062 rewack the locations of include, bfd, and getopt in its output.
4064 * README: Document moving include files, improve some of
4067 * coffread.c: Move common code out to symfile.c. Change
4068 symbol_file_command style interface to use new *_symfile_init
4069 and *_symfile_read interface under BFD. Use BFD internal
4070 info to locate line table, symbols, etc.
4072 * core.c (core_fetch_registers): Rename to get_core_registers
4073 to avoid confusion with fetch_core_registers.
4074 (register_addr): Move to coredep.c, which is already machine
4075 dependent. This leaves core.c pretty clean of dependencies.
4077 * coredep.c (register_addr): Accept this routine from core.c.
4079 * dbxread.c: Move common code (with coffread.c, etc) into new
4080 symfile.c. Each psymtab now contains a pointer to the
4081 format-dependent function that knows how to read it in. Make
4083 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4084 (process_one_symbol): Add code to complain about a "compiler bug
4085 we muzzle here", if we actually see it.
4087 * eval.c (evaluate_subexp): Insert missing "break" statements
4088 in code that determines whether a variable is an lvalue in
4089 memory, register, or whatever. I detected this via a compiler
4090 bug in which it *almost* mashed out the whole switch statement.
4092 * gdb-int.texinfo: Add minor sections on configuring gdb for
4093 release, and about the README file.
4095 * infcmd.c (registers_info): Fix formatting somewhat. Still
4096 not as pretty as before, but it handles byte swapping.
4098 * remote-nindy.c: If data cache routines are interrupted while
4099 waiting for the remote end, be sure that any uninitialized cache
4100 blocks are on the free list, not on the valid list!
4102 * symfile.h: Flesh out this header file with all the various
4103 routines and variables that have been merged in from dbxread.c
4104 coffread.c, and symtab.c to symfile.c.
4106 * symfile.c: New file, containing code common to dbxread.c,
4107 coffread.c, and some code from symtab.c. All generic code for
4108 reading symbol files should be in here now.
4109 (unrecord_misc_function): Remove unused function.
4111 * symtab.h: Remove file-reading things to symfile.h.
4113 * symtab.c: Remove file-reading things to symfile.c.
4115 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4116 to decode i960 fault types.
4118 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4119 target.c: Change type of the "resume" function from int to void,
4120 since its result was never used.
4122 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4124 * main.c: Replace "stupid" with "caution"; you now "set caution
4127 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4129 * infcmd.c (do_registers_info): Call val_print to deal with the
4130 byte order of the registers being printed. FIXME, this makes
4131 the formatting of the output uglier.
4133 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4134 defined, call it for signals the debugger doesn't itself use.
4135 The i960 uses this for more detailed fault information.
4137 * remote.c (remote_open): If arg is null, print help rather than
4140 * sparc-xdep.c (register_valid): Avoid declaring size, since
4141 various modules will think of various sizes depending on the
4142 architecture of their tm-file. FIXME, we need protection against
4143 actually entering one of those modules, which would clobber
4144 storage if not for the target architecture compiled into gdb.
4146 * stack.c (up_command, down_command): Always print the frame
4148 (up_silently_command, down_silently_command): New commands
4151 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4153 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4154 more parameters than it used to.
4156 * findvar.c (registers): Increase slop to 256 bytes, which should
4157 protect us against even most RISC machines with large register
4159 (locate_var_value): Move declaration inside related ifdef.
4161 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4162 throughout, to avoid throwing away buffered input from the board.
4163 (nindy_wait): Supply_register takes addr_of_value, not value.
4164 (i960_print_fault): Renamed from i80960_fault.
4165 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4166 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4168 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4169 we can set the PC in the call to proceed(). Unpush nindy_ops
4170 before pushing it on top, to avoid message to user. Eliminate
4171 commentary from Unix machines that just misleads here.
4172 (reset_command): Fix error message to suggest target command.
4174 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4176 Release 3.92.5 as frozen.
4178 Stabilize the merged release...with help from lint, Saber C,
4181 Everywhere: Add include files needed to declare return types
4182 of functions called.
4184 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4186 * breakpoint.h: Add undeclared breakpoint functions, and some
4187 functions for display handling since I couldn't think of a better
4190 * breakpoint.c (insert_breakpoints): Make code for disabling
4191 shared library bkpts more likely to work. It's used when we
4192 rerun a program and stop before the shared library has been
4194 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4195 cast from pointer, so it squeezes through catch_errors.
4196 (bpstat_stop_status): Fix logic broken some time ago. We now
4197 always create a bpstat if the stop address matches a breakpoint,
4198 even if we don't stop there -- just like the old code used to do
4199 before I got my fingers into it (sigh).
4200 (breakpoint_1): Print "ignore count" after "stop only if"
4201 condition, since that's how it actually works.
4202 (mention): Handle watchpoints as well as breakpoints.
4203 (watch_command): use set_raw_breakpoint and mention to do most
4204 of the work (and initialize all the fields!). Only pass one
4205 arg to parse_c_expression, since that's all it takes.
4207 * command.c (not_just_help_class_command): Rename arg to args
4208 since we ignore "unused argument" warnings on vars named "args".
4209 inflow.c (child_terminal_info): ditto.
4210 infptrace.c (kill_inferior): ditto
4211 main.c (catch_errors, version_info, quit_command, pwd_command,
4212 source_command, dump_me_command, editing_info,
4213 set_history_size_command, set_history, show_history,
4215 stack.c (locals_info): ditto
4216 target.c (target_files_info): ditto
4217 valprint.c (set_input_radix, set_output_radix): ditto
4219 * core.c: Remove old variables for handling core and exec file
4220 sections (data_start, data_end, stack_start, stack_end,
4221 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4222 text_end, exec_data_start, exec_data_end, text_offset,
4223 exec_data_offset, data_offset, stack_offset). They're
4224 superseded the more general build_section_table and
4226 (get_exec_file): Mention the `file' command.
4227 (read_memory_check): Rename to memory_error, and only call it
4228 in the case of an actual error.
4229 (read_memory, write_memory): call memory_error.
4230 (core_fetch_registers): Register section name is ".reg".
4232 coredep.c: Remove a bunch of crud now that all this file does
4233 is pull the registers out of a core file.
4234 (fetch_core_registers): Rewrite to actually work, I hope.
4236 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4237 Replace index() with strchr(). Remove all the pre-BFD macro
4238 definitions for accessing the symbol file.
4239 (struct dbx_symfile_info): Encapsulate the information that
4240 dbx_symfile_init needs to pass to dbx_symfile_read in this
4243 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4244 dbx_symfile_discard): Rearrange symbol file reading to divide
4245 the format-specific part from the format-independent part,
4246 leaving the format-independent part such as file name expansion
4247 and opening in symtab.c. This replaces
4248 partial_symbol_file_open and partial_symbol_file_read.
4249 Symbol_file_read, add_file, add_file_target_command,
4250 add_file_addr_command move to symtab.c. Pass an explicit
4251 "mainline" flag for when reading the main symbol table, rather
4252 than relying on the offset address to be zero or nonzero.
4254 (dbx_symfile_read): Don't allow void *'s to be printed as
4256 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4257 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4258 macro" debug version really work.
4259 (read_dbx_symtab): Remove unref'd parameter inclink.
4260 Avoid swapping N_SLINE symbols, for speed.
4261 Merge N_TEXT!N_EXT case with the other external symbol
4262 definitions' case. Add comments.
4263 (start_psymtab): Allocate the symfile name in the psymtab on
4264 the psymbol_obstack, rather than using the caller's storage.
4265 (end_psymtab): Only allocate a dependencies list if there are
4267 (psymtab_to_symtab_2): Use BFD when reopening file to read
4268 its symbols for real.
4269 (read_struct_type): Add FIXME comments where it needs work
4271 (read_huge_number): Add FIXME about overflows.
4272 (read_range_type): Add FIXME about comparing a long to 1<<32.
4274 * coffread.c: Minor changes to move things closer to the new
4275 regime with symtab.c and dbxread.c Major work is still needed
4278 * exec.c (exec_file_command): Remove old variables (see core.c
4280 (xfer_memory): If memory transfer is right at the end of a
4281 section, don't lose.
4283 * findvar.c (get_saved_register): If value is in a real
4284 register, LVAL is lval_register, not lval_memory.
4286 frame.h: Declare print_sel_frame and record_selected_frame.
4288 gdb-int.texinfo: New file, for GDB internals documentation.
4289 Very simple, unformatted doc of cleanups is there for now.
4291 gdbcore.h: Remove obsolete variables that described a.out
4292 section addresses and offsets. (See core.c above.)
4293 Declare fetch_core_registers and registers_fetched.
4295 getopt.c: Declare char *alloca(); even on SPARC.
4297 infcmd.c (run_command): Call target_kill rather than
4299 (step_command, next_command, stepi_command, nexti_command):
4300 Declare from_tty parameter even though we don't use it.
4301 (run_stack_dummy): argument BUFFER is a char array, not
4302 a pointer to REGISTER_TYPE.
4303 (finish_command): using_struct_return needed a value *,
4304 not a struct symbol *.
4306 * infptrace.c (child_xfer_memory): To avoid dependency on
4307 where sections are in memory, try PT_WRITE_D and if that fails,
4308 try PT_WRITE_I. Most Unixes don't care which you use.
4310 * infrun.c (step_resume_break_shadow): Change to array to
4311 match other breakpoint shadow storage.
4312 (clear_proceed_status): Pass address of bpstat to
4313 bpstat_clear, not the bpstat itself.
4314 (child_create_inferior): FIXME comment about if the child
4316 (start_inferior): Remove old function.
4317 (child_open): Use target_kill rather than kill_inferior.
4318 (wait_for_inferior): Ditto.
4319 (insert_step_breakpoint, remote_step_breakpoint): Use
4320 new step_resume_break_shadow.
4322 * inftarg.c (child_wait): If all child processes die,
4323 pretend that the one being waited for exited with signal 42.
4325 * main.c (command_line_input): When scanning for comments,
4326 don't coredump on unclosed quotes.
4327 (quit_command): Use target_kill rther than kill_inferior.
4328 (_initialize_main): Rename class_user from "user" to
4331 * printcmd.c (print_command_1): Initialize "fmt" if no format
4332 is specified by the user.
4333 (print_frame_args): Only add to args_printed if we are
4334 actually fetching args from the stack (avoiding undefined
4336 (_initialize_printcmd): Remove bogus \{ from string.
4338 * remote-eb.c (eb_open): Avoid coredump on no argument.
4340 * remote-nindy.c: Bring out of Intel environment into new
4341 target environment. Remove all conditional compilation on
4342 I80960. Massive hacking throughout.
4343 (nindy_xfer_inferior_memory): New routine stolen from
4345 (nindy_create_inferior): New routine pieced together, probably
4346 not quite working yet.
4347 (nindy_ops): New target_ops struct for nindy.
4349 * remote-vx.c: Use write_memory rather than target_write_memory
4350 to get error checking.
4351 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4353 (vx_create_inferior): Use target_terminal_ours...
4355 * signame.c (_initialize_signame): Always initialize, since
4356 we need the table for things other than psignal.
4358 * solib.c (solib_add): Use symbol_file_add, not add_file.
4359 (solib_address): Return boolean result rather than struct
4360 pointer which nobody else knows the type of.
4362 * sparc-tdep.c, valops.c: Use write_memory rather than
4363 target_write_memory, to get error checking.
4365 * stack.c (locals_info, catch_info, args_info,
4366 get_selected_block, frame_command, up_command): Use
4367 target_has_stack, rather than have_inferior_p or
4370 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4372 * symfile.h: New file, defining the interface between the
4373 generic and object-file-specific symbol reading code.
4375 * symtab.c: Move generic symbol-reading interface to symtab.c,
4376 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4377 table to map BFD targets to symbol-reading modules in GDB.
4378 Change index to strchr.
4379 (lookup_struct_elt_type): Use error() rather than hand-made
4380 simulations thereof.
4381 (lookup_partial_symbol): Speedup slightly when length == 0.
4382 (symbol_file_add): New function.
4383 (symbol_file_command): Call it.
4384 (symfile_open, symfile_init): New function.
4385 (add_file_target_command, add_file_addr_command): moved from
4388 * target.c (target_command): use target_kill.
4390 * target.h (target_files_info): Don't declare, never called
4393 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4394 files to determine stack end address.
4396 * valarith.c (value_x_binop, value_x_unop): Change error message
4397 to be more useful. Pass proper argument to value_struct_elt.
4399 * valops.c (value_assign): FIXME comment that long long
4400 bitfields will break here.
4402 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4403 Update `make saber_gdb' to work better.
4405 * TODO: A woman's work is never done.
4407 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4408 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4409 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4410 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4411 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4412 valops.c, valprint.c, exec.c: Lint.
4415 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4417 Continuing Intel 960 port merge of GDB.
4419 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4420 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4421 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4422 Wack over "make depend" so it handles files in subdirectories
4423 vx-share, nindy-share, bfd, and in the current directory.
4425 * blockframe.c (get_prev_frame_info): Remove fatal error
4426 if stack not defined.
4428 * core.c (core_open, core_detach): New functions that handle
4429 the old "core-file" command as "target core" and "detach" instead.
4430 (core_file_command): Call them.
4431 (core_xfer_memory): Use common routine xfer_memory.
4433 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4434 dbxread now uses bfd for everything but symbol reading itself.
4435 BFD internals are used to drag out the relevant file offsets.
4436 (partial_symbol_file_open): Change args all around for BFD.
4438 * symtab.c: Rename "value" to "val" everywhere, so we can
4440 (symbol_file_command): New command, moved from dbxread.c
4441 and coffread.c. It uses BFD to read the file, then vectors
4442 based on its type, to dbx or coff symbol readers.
4443 * symtab.h: Extern a few vars for symbol_file_command.
4445 * target.h: Breakpoint takes a char * save area, not a char **.
4447 * valprint.c (val_print): When unpacking bitfields, offset
4448 the address in gdb of the value, if it is declared with a shorter
4449 type. Remove the last "runtime kludge test" of host byte order.
4451 * utils.c: Remove old my_bfd_read routine.
4453 * stack.c (frame_info): Use target_has_stack. Print program counter
4454 register's actual name rather than "pc", since it's called the
4455 "ip" (instruction pointer) on the i960 (sigh).
4457 * target.c (target_command): Add command for selecting a target
4458 type and calling its open routine. This is used for initiating
4459 communication with a particular target, in a generic way.
4461 * tm-i960.h: Update for modern gdb. Remove semicolons from
4462 various macros. Handle reading struct return convention, and
4463 error-out attempts to return structs with the "return" command.
4464 Be sure gdb doesn't think we know how to call functions in the
4467 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4468 to i960_xxx in lower case.
4469 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4470 not being defined yet.
4472 * remote.c (remote_open): Call start_remote to initialize
4473 wait_for_inferior during open.
4474 (remote_xfer_inferior_memory): Return length written rather
4477 * remote-vx.c (target_command -> vx_open): Use new generic
4479 * remote-eb.c, inftarg.c, exec.c: ditto.
4481 * infrun.c: Fix comments.
4482 (attach_program -> child_open): Use new generic target command.
4483 (wait_for_inferior): Clear saved register values before target_wait,
4484 so target_wait can set some of them if convenient.
4486 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4487 Return success indicator, not void.
4488 (child_xfer_memory): Avoid fetching initial word if we'll
4489 overwrite it anyway.
4491 * infcmd.c (attach_command): Use new generic target open routine.
4492 (_initialize_infcmd): Update doc on attach and detach commands.
4493 (do_registers_info): Merge in a byte-order problem as a FIXME
4496 * findvar.c (find_saved_register): Avoid problem in current frame.
4497 (read_relative_register): Ditto.
4498 (write_register): Convert byte order on the way out.
4500 * exec.c (file_command): Add.
4501 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4502 (xfer_memory): Common function between core_xfer_memory and
4504 (exec_xfer_memory): Use it.
4506 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4508 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4509 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4510 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4512 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4514 Merge Intel 960 port of gdb, continuing...
4516 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4517 symbol_file_command): Pass from_tty arg to hush 'em up.
4519 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4520 Add magic numbers for 960 COFF format.
4522 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4524 Merge Intel 960 port of gdb, from Intel "1.2" release.
4526 CHANGE_LOG entries from their port, which was based on
4529 Thu Sep 6 11:02:22 PDT 1990
4530 Remove temp file if download is interrupted.
4532 Wed Aug 1 09:08:33 PDT 1990
4533 Now uses binary protocol to talk to NINDY.
4534 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
4535 Times out after 5 seconds when trying to talk to NINDY.
4537 Tue May 29 12:54:49 PDT 1990
4538 Added variable baud rate (-b switch).
4539 Source code reorganization.
4541 Thu Apr 26 11:09:55 PDT 1990
4542 More cleanup of batch mode; specifically, execute "-s", "-e", and
4543 "-se" switches as soon as they are encountered on the invocation line.
4545 Fri Apr 20 13:47:15 PDT 1990
4548 Thu Apr 19 09:54:28 PDT 1990
4549 Add 'reset' command.
4551 Wed Apr 18 09:48:07 PDT 1990
4552 After opening remote tty, wait for 1 second to go by without input
4553 from it before trying to talk to NINDY (fixes problems with the
4554 Heurikon HK80/V960E).
4556 Mon Apr 4 16:33:05 PDT 1990
4557 Some output was not being suppressed in 'batch' mode.
4559 Thu Mar 22 15:31:11 PST 1990
4560 Ask user if old symbol table should be deleted when new file is
4563 Allow user to run a program downloaded before gdb960 was brought up.
4565 Correct "exec-file" help message for i80960 context.
4567 Correct bug in calculating user space address: could occasionally
4568 corrupt user program.
4570 Make sure to zero low-order bits in rip's because of bug in 960CA
4571 A-step part: could cause operation faults when "next"ing across
4574 Correct bug that made it impossible to get source line numbers for
4575 code loaded at addresses higher than 0x7fffffff.
4577 Wed Jan 10 12:43:22 PST 1990
4578 Open remote tty for exclusive use.
4580 Fri Jan 5 12:14:42 PST 1990
4581 Correct disassembly (CA manual was right after all):
4582 opcode for sysctl is 0x659
4584 Mon Oct 23 12:03:04 PDT 1989
4585 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4587 Mon Oct 16 14:15:09 PDT 1989
4588 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4590 Mon Oct 2 15:56:31 PDT 1989
4592 Added 960CA disassembly support.
4594 To simplify maintenance:
4595 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4597 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4598 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4599 - made disassembly interface identical to that in gdmp960.
4603 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4605 * target.h: Allow targets to stack. Add target_has_memory,
4606 _registers, etc. Restructure memory access and "info files"
4607 to walk the target stack.
4608 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4609 target.c: Change tables to match target.h.
4610 * inflow.c (child_mourn_inferior): pop child_ops.
4611 (generic_mourn_inferior): Use new has_stack flag.
4612 * infptrace.c (child_xfer_memory): New memory regime.
4613 * inftarg.c (child_files_info): New "info files" regime.
4614 * remote-eb.c: New memory regime, new info files.
4615 * remote-vx.c: New memory regime, new info files. Now use
4616 separate targets for VxWorks attachment to machine, and
4617 actually running a process under VxWorks, since one has
4618 stack & execution & regs and the other doesn't.
4619 * remote.c: New memory regime, new info files.
4620 * sparc-xdep.c (fetch_core-registers): New memory regime.
4621 * target.c: New routines and support for stacked targets,
4622 new memory regime, new info files regime.
4625 Generalize section handling for an arbitrary number of sections,
4626 including use of the new BFD (binary file) library.
4627 * gdbcore.h: Add struct section_table.
4628 * exec.c (build_section_table): Iterate all sections and
4629 record what gdb needs to know about them.
4630 (exec_command): Use it.
4631 (exec_xfer_memory): Use the table.
4632 (exec_files_info): Print the table.
4633 * core.c (core_file_command, core_xfer_memory, core_files_info):
4635 * source.c (find_source_lines): Use bfd_get_mtime.
4636 * dbxread.c: Quick changes to make it compile with new BFD.
4637 * utils.c (error): Avoid using bfd_error in generic routines.
4639 * core.c (core_fetch_registers): Get from the ".regs" section of
4641 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4643 * inferior.h (attach_flag): Export.
4644 * infcmd.c (run_command): use new target_create_inferior.
4645 * infrun.c (child_create_inferior): Don't return result.
4646 * Makefile.dist (VERSION): 3.91.4.
4648 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
4650 * breakpoint.c (bpstat_num): Handle breakpoints which have
4651 since been deleted, such as temporary breakpoints.
4652 infcmd.c (program_info): ditto.
4654 * core.c (core_file_command): Display the frame where the core
4659 * remote-vx.c (target_command): Merge in target command from
4660 targ-vx.c. A few other cleanups.
4662 * TODO, Projects: Lots more stuff to do...
4664 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4666 Massive changes to wall off the remote-debugging interface
4667 behind a function vector. The port to handle VxWorks targets
4668 is also part of this.
4670 All files: Replace references to renamed functions,
4671 remove references to remote_debugging, remove references to
4672 have_include_file, have_core_file in favor of target_has_stack,
4673 target_has_memory, etc.
4675 * Modularize the breakpoint interface.
4676 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4677 a breakpoint instruction.
4678 breakpoint.c: struct breakpoint's shadow_contents now sized as
4680 (insert_breakpoints): Vector to target to install breakpoints.
4681 (remove_breakpoints): Vector to target here too.
4682 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4683 sparc-tdep.c (single_step): Use new breakpoint interface for
4684 the single-step breakpoints.
4685 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4686 New file, contains routines to insert and remove breakpoints by
4687 reading out the old contents and later replacing them. This is
4688 how ptrace breakpoints work, and many remote systems as well.
4690 * tm-vxworks68.h: New config file, overrides a few things for
4691 Wind River's preferences.
4693 * target.h: New file, for transfer vector used to talk to the
4694 inferior (child, attached, core, exec, remote, etc). All accesses
4695 to the thing being debugged should come through these vectors.
4696 target.c: New file, routines to handle transfer vector.
4697 (various files): Add transfer vectors XXX_ops for the various
4698 targets and pseudo-targets (core files, etc) we support.
4700 * breakpoint.c (bpstat_stop_status): Further explorations of
4701 watchpoints and why things don't work all the time.
4702 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4704 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4705 the local gdbinit if it doesn't already have it.
4707 * core.c (core_ops): add and install.
4708 Allow core debugging without exec file.
4710 * dbxread.c (free_and_init_header_files): Merge two fns.
4711 (end_symtab): Free named symbol table when a new version comes in.
4712 (read_dbx_symtab): Relocate all kinds of symbols with base
4713 address. First step toward handling different text, data, bss
4715 (add_file_addr_command): Renamed add_file_command.
4716 (add_file_command): Vector to remote handler.
4717 Add "load" as an alias for "add-file" command.
4719 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4720 non-returning functions.
4722 * exec.c: Add exec_ops, and push it as a target when an exec
4725 * infcmd.c (run_command): Pass executable file name and arg list
4726 separately when starting an inferior. Permit "run" when no exec
4727 file is specified, for VxWorks.
4728 (detach_command): Move to child_detach in inftarg.c.
4730 * inftarg.c: New file. Unix-child-specific routines, and the
4731 child_ops structure.
4733 * inferior.h (registers): Export "registers" as the way for
4734 target dependent register handlers to find gdb's local copy of
4735 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4736 since it is now used by places that want wait_for_inferior to
4737 handle the grunge but want to see every trap from the inferior.
4739 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4740 Eliminate remote_debugging hooks in terminal handling.
4742 * infrun.c: Replace start_inferior with child_create_inferior.
4743 Move all the hair of Unix shells and ptrace idiosyncracies into
4744 child_create_inferior, so remote handlers don't have to deal.
4745 Remove running_in_shell. Rename stop_after_attach to
4746 stop_soon_quietly, and use it in a few other places where we want
4747 to just call wait_for_inferior and get control back on the first
4748 trap. trap_expected now never takes a value > 1.
4749 (init_wait_for_inferior): Initialize static vars when a new
4752 main.c (gdbinit): Add new hook for .gdbinit file name, let
4753 it be overridden by config files as GDBINIT_FILENAME.
4754 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4755 Both of these are used for VxWorks gdb.
4757 mcheck.c: rename include file "gmalloc.c" to avoid problems
4758 with system include file "malloc.c".
4760 param-no-tm.h: New include file, same as param.h but does not
4761 include the default "tm.h" file. This is used in files where
4762 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4764 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4766 remote-vx.c: New file, VxWorks remote debugging support. Uses
4767 RPC routines that are shared with the target system, in directory
4770 remote.c: Vectorize remote interface.
4772 source.c: Globalize source_path, and make an alias "l" for "list"
4773 since we now have the "load" command.
4775 sparc-xdep.c: Use new param-no-tm.h.
4777 symmisc.c (free_named_symtab): Add new function from Wind River.
4778 However, ifdef it out for now while we think about what it should
4781 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4783 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4784 non-Unix-children handle this with their own code in the target
4787 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4788 source and target lists. Add vx-share to default list of include
4789 directories. Add new files to src and target lists: mem-break,
4790 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4791 ${srcdir} versions of munch and createtags are used.
4793 * valops.c (find_function_addr): Split out of call_function.
4794 (call_function_by_hand): Rename call_function; this function
4795 calls functions in the target by laboriously patching the target
4796 word-by-word with the right stack, args, regs, etc.
4799 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
4801 Handle AMD 29000 a bit better.
4803 * remote-eb.c (readchar): Mask received char log to make it readable.
4804 (remote_start): Pass arguments down to executing program.
4805 Make startaddr unsigned.
4806 infrun.c (start_inferior): Accept args, pass them to
4808 infcmd.c (run_command): Pass args down to start_inferior.
4810 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
4811 the target object file format.
4812 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
4814 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
4815 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
4817 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
4819 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
4820 * TODO: We did a few things, we have more to do though.
4822 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
4823 * inflow.c (inferior_died): Clear deferred stores.
4825 * Debug problems with dummy frames and calls to the inferior.
4826 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
4827 * sparc-tdep.c (do_restore_insn): Simplify.
4828 (sparc_frame_find_saved_regs): Simplify and fix what we find.
4829 (sparc_push_dummy_frame): Simplify and fix what we push.
4830 (sparc_pop_frame): Slightly more hair here, deciding whether
4831 we are restoring a saved PC or returning to a return address in %i7.
4832 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
4834 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
4835 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
4836 * obstack.h (chunkfun): ditto.
4837 * defs.h (xmalloc, xrealloc): ditto
4839 * utils.c (quit): Grab the terminal from the child if necessary.
4841 * inflow.c (term_status_command): Rename to term_info, change
4844 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
4845 (is_delayed_branch): Speed up.
4846 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
4847 Still missing some float ops, and needs testing.
4849 * Support for input and output radixes other than base 10
4850 * defs.h (input_radix, output_radix): Declare.
4851 * expread.y (yyparse, parse_number): Handle changes of input
4852 radix, and ambiguous names-or-numbers in radixes >10.
4853 * printcmd.c (print_scalar_formatted): Print formatted hex
4854 numbers in varying column widths.
4855 * valprint.c (val_print): Use output_format to print scalar ints.
4856 (set_input_radix, set_output_radix, set_radix): Create.
4857 (set_output_radix): Set output_format from output_radix.
4858 (_initialize_valprint): add `set radix' but leave the others off.
4860 * main.c (execute_command): Let stupid questions be turned off.
4861 (_initialize_main): Handle "set stupidity", etc.
4863 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
4864 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
4866 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
4868 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
4869 bfd stuff is still screwed up, but with some manual work, it
4872 * breakpoint.c (bpstat_do_actions): Start over if a command
4873 proceeds the inferior, since the inferior will have stopped and
4874 will need to have its new stop-actions taken care of.
4876 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
4877 compiler fits, simplify it.
4879 * gdb.texinfo (directory command): Doc new dir command.
4880 source.c (directory_command): "dir" now puts things on the front
4881 of the path, moves dups up front, and handles multiple names
4882 on the command line, inserting each one in order. It also
4883 blows away cached line and full_filename info.
4885 * stack.c (backtrace_command): Skip "more stack frames follow"
4888 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
4889 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
4890 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
4891 The only odd one was Gould NP1, which had defined vprintf to
4894 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
4895 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
4896 variable, inspect_it.
4897 valprint.c (print_string, val_print): Use the global inspect_it
4898 to indicate whether to print in Epoch style or normal style.
4900 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
4902 * printcmd.c (call_command): add an alias for the "print" command
4903 which runs expressions and doesn't print the result if void.
4904 (print_command_1): implement it.
4906 * command.c: Remove #if 0'd code. Initialize all the fields
4907 in add_cmd (). Rename do_nothing_command to
4908 not_just_help_class_command, and make it externally visible.
4909 command.h: add user_commands to struct.
4910 * main.c (define_command): Don't overload c->function with a char
4911 string as well as a function pointer.
4913 * eval.c (evaluate_subexp): Reinstall tiemann changes to
4914 calling convention of value_struct_elt () that got dropped in
4917 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
4918 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
4920 * tm-sparc.h (POP_FRAME): replace some constants with defines.
4922 * sparc-xdep.c (store_inferior_registers): defer stores to regs
4923 until a good time (e.g. when we are about to run the child),
4924 saving ptrace calls.
4925 * infrun.c (proceed): handle DO_DEFERRED_STORES.
4926 * tm-sparc.h: define DO_DEFERRED_STORES.
4928 * sparc-xdep.c (store_inferior_registers): when storing float
4929 registers, don't store stack regs too. When storing the SP,
4930 however, DO store the stack regs too. This fixes a bug in which
4931 the dummy frame is not recognized when a call_function finishes,
4932 because its frame pointer (in the stack regs) was never
4934 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
4935 even though we don't know how to read them from an inferior.
4936 valops.c (call_function): Comment about storing SP.
4938 * infrun.c (save_inferior_status): Save away the original bpstat
4939 chain so it can be restored later. Install the copied version for
4940 use by whoever saved the status. It will be blow away by
4941 restore_inferior_status, and the original chain restored. This is
4942 important for people who have pointers into the original.
4944 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
4945 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
4946 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
4949 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
4951 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
4952 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
4953 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
4955 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
4957 * Merge Mike Tiemann's multiple inheritance changes from Sun.
4958 Store the baseclasses in a type struct starting from array element
4959 0 rather than from the unusual array element 1.
4961 dbxread.c: the above.
4962 (virtual_context): Add
4963 Read new debug information about which virtual function table
4964 a virtual function is from, and store it in fn_field.fcontext.
4966 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
4967 TYPE_FN_FIELD_STATIC_P.
4969 symtab.c: the above.
4970 valops.c: the above. Handle pointer casts of object *'s.
4971 (search_struct_method): Add.
4972 (value_struct_elt): First arg is now a pointer to a value, and is
4975 valprint.c: the above.
4976 values.c (value_virtual_fn_field): Add type arg. Handle
4977 offsetting to the proper object when calling virtual fns.
4979 (baseclass_addr): Add valuep arg.
4981 * README: Document the current state of BFD config (missing).
4982 * TODO, ChangeLog, Makefile.dist: Roll version.
4983 * WHATS.NEW: Add summary of changes since 3.5.
4985 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
4987 * dbxread.c (read_struct_type): Clear bit vectors whenever
4989 symtab.c (B_CLRALL): define.
4991 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
4992 using == rather than =. Huh... This fixes the dreaded problem
4993 wherein builtin_type_int becomes TYPE_CODE_FLT.
4995 * core.c (info_files): Show the inferior pid.
4997 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
4998 already knows how to look in the source directory.
5000 * Remove psymtab hair from many places. Remove duplicated code
5001 for searching symbol tables. Hide psymtabs from most places.
5002 Make it fast to get from a psymtab to its symtab.
5004 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5005 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5006 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5007 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5008 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5009 new symtab completely. New psymtabs get symtab pointer
5010 initialized to zero. Remove MI warning printf.
5011 symtab.h: Comments. Add psymtab to symtab pointer.
5012 (PSYMTAB_TO_SYMTAB): New macro.
5013 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5014 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5016 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5018 (print_frame_info): Avoid special-casing symbols that have not yet
5021 * source.c (open_source_file): Quick path if we have already
5022 located the source file by its full name.
5024 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5025 find_pc_psymtab. When a name is found in the misc function
5026 vector, search the symbol table for its mangled name, not the
5027 name that the user typed.
5029 * bfd.h: Fix missing comment terminators, make #endifs match.
5031 * valarith.c (value_less): Handle unsigned int comparisons.
5032 Add FIXME about pointer compares, which assume host and target
5033 pointers are the same.
5035 * command.c (do_nothing_command): lint
5036 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5037 fix comments on debug symbol format for visibility. Actually set
5038 visibility of symbols.
5039 main.c (echo_command): lint; use <readline/history.h>.
5040 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5041 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5042 pointing past end of allocated memory; saber complains.
5043 obstack.h: Declare the external functions that we use.
5044 valarith.h: use <string.h>
5045 solib.c (solib_add): lint.
5047 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5049 * main.c (initialize_main): Default info_verbose to off, now that
5050 symbol reading is fast.
5051 (quit_command): Avoid clobbering exec_bfd while quitting.
5053 * Initial BFD (binary file diddling library) merger:
5054 coffread.c: Change AOUTHDR to struct exe_hdr.
5056 core.c: initialize initialized data at compile time.
5057 (core_file_command): Move from coredep.c, convert to bfd.
5058 (xfer_core_file): Convert to bfd.
5059 exec.c (exec_file_command): use bfd routines.
5061 mips-tdep.c: Remove exec_file_command and friends.
5064 * coredep.c: (fetch_core_registers) Convert core_file_command to
5065 fetch_core_registers.
5066 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5068 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5069 (my_bfd_read): More bogosity, which I don't think we call.
5070 (program_name): Remove this atrocity asap!
5072 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5075 values.c: allocate_repeat_value was not clearing the
5076 optimized_out field.
5077 (value_static_field): minor stylistic fix (wrong macro was used).
5078 valops.c (value_struct_elt_for_address): didn't work for C++
5081 * signame.c (_initialize_signame): Initialize signal names once.
5083 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5084 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5085 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5087 * remote-eb.c: Support user-settable baud rates on the serial port.
5089 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5091 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5093 * tconfig/sun3os4: Remove warning about native assembler,
5094 since it also occurs in the xconfig file.
5096 * findvar.c (registers): Allocate some slop after `registers'
5097 to prevent stray accesses from trashing the next variable.
5099 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5100 on the sun-3, by changing the #ifdef from `sun3' (which is not
5101 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5102 vars, which happened to follow `registers' in the executable.
5104 * readline/history.c (history_search): Heed gcc-2's advice
5105 and parenthesize && inside ||).
5107 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5108 tm-29k.c: Insert FSF copyright headers.
5110 * remote-eb.c: Better comments.
5112 * Makefile.dist: Update to 3.91.6.
5113 * TODO: note PREPARE_TO_STORE problem.
5115 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5117 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5119 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5121 * infrun.c (wait_for_inferior, at end): Don't set up
5122 prev_* if the inferior no longer exists.
5124 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5125 CANNOT_EXECUTE_STACK.
5126 valops.c (call_function): Use it.
5128 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5130 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5131 infrun.c (wait_for_inferior, 2 places): Use it.
5133 * values.c (value_being_returned): Only use
5134 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5136 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5137 right thing for remote-eb.c.
5139 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5140 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5142 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5143 (FRAME_FIND_SAVED_REGS).
5145 * findvar.c ({fetch,store}_registers): Check for
5146 REMOTE_{FETCH_STORE}_REGISTER macro.
5148 * findvar.c (get_saved_register): Add argument lval and
5149 change meaning of argument addr.
5150 findvar.c: Change calls to get_saved_register to reflect
5151 new calling convention.
5152 valops.c (value_assign): Use get_saved_register instead of
5153 find_saved_register.
5155 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5157 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5158 an (uninitialized) pointer to one. Use "&" when passing it
5161 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5163 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5166 * coffread.c (symbol_file_command): Put semicolon after
5168 Put safe_to_init_tdesc_context in #if defined (TDESC).
5169 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5170 coffread.c: #include <sys/stat.h>.
5171 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5172 Add missing ')' in check for "lc%" and friends. Remove
5174 Declare read_one_sym() at top of file.
5175 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5176 MC68WRMAGIC can have the same value without causing a duplicate
5179 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5181 * Allow a Makefile to be built without building the
5182 tm and xm file links that screw up builds in subdirectories.
5183 This is done with `config.gdb none', then you can do things
5184 like `make gdb.tar.Z'.
5185 * tconfig/none: Config file for no target system
5186 * xconfig/none: Config file for no host system
5187 * config.gdb: If no TM or XM files are called out by the
5188 host or target file, don't make links for them.
5190 * cplus-dem.c: Add documentation.
5192 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5193 simple error, so the user's gdb doesn't crash due to some object
5194 file problem (e.g. somebody is rebuilding the file out from under
5197 * printcmd.c (print_address_symbolic): demangle the symbol.
5199 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5200 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5201 (alldeps.mak): sort and uniq all results from this; duplicates
5202 hose gdb.tar.Z link building. Remove RCS files from
5203 tconfig and xconfig. Add config files for sun386. Add
5204 a few odd files to OTHERS and HFILES.
5206 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5208 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5209 Roll version number to 3.91.5. Make lint work in bindir.
5211 * README: Document cross-debugging and new file structure.
5213 * blockframe.c: Lint. Include "value.h" to declare read_register.
5214 (find_pc_partial_function): remove duplicate line.
5216 * command.h: Lint. Declare error_no_arg and dont_repeat.
5218 * tm-news.h: Remove inadvertently duplicated stuff.
5220 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5221 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5223 * config.gdb: Allow `config.gdb host target' form. Clean
5224 up previous change that printed bogus messages when you just said
5227 * core.c: #include "command.h" for lint.
5230 * main.c: Remove some casts of enums. Lint.
5237 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5239 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5240 read it from memory. This will allow us to save ptrace calls
5241 eventually. Changed caller single_step too.
5243 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5244 that we aren't going to use, saving many ptrace calls, especially
5245 when watchpointing or single stepping. Use some #define's for
5247 (store_inferior_registers): Ditto.
5248 (core_file_command): Use some #define's for constants.
5250 * tm-sparc.h: Add #define's for some register numbers, so we
5251 can eliminate the use of random constants in sparc-xdep.c.
5253 * stack.c (frame_command, print_frame_info, up_command,
5254 down_command) Remove frame_changed, since it
5255 causes a bug and doesn't seem to do anything useful. In some
5256 places it was used as a flag, in others as a stack level (?).
5258 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5259 default is to use the portable (vprintf) version rather than the
5261 * xm-news.h (MISSING_VPRINTF): Add.
5263 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5265 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5267 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5268 about linking debugged programs -Bstatic in the sun?os4 config
5269 files in tconfig and xconfig subdirectories.
5271 * main.c (main): Remove unreached exit(0) now that we exit
5274 * Create TODO file for online bug list. There are too many
5275 "little" bugs to keep track of on paper.
5277 * Change Projects file to refer to bug-gdb@cygnus.com
5278 rather than kingdon@ai.
5280 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5282 * Makefile.dist (VERSION): 3.91.4 now.
5284 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5285 (condense_misc_bunches): Add sanity check that misc_count is
5286 the same as the number of symbols in the bunch.
5288 * coffread.c: rename init_misc_bunches. Pass an argument
5289 to condense_misc_bunches (a zero).
5291 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5292 every time we are called; don't rely on our caller to do it.
5293 (add_file): Remove call to init_misc_bunches.
5295 * mipsread.c: Only warn, don't error, if unknown symbol types.
5296 This keeps an old gdb from falling on its face if it sees newly
5297 extended symbol info. Rename init_misc_bunches.
5299 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5301 * Merge in changes from Per Bothner for DECstations and other
5302 MIPS stuff. The rest is Bothner speaking:
5304 The next message is a merger of Alessando Forin's mips port with
5305 mine. I've tried to use my good if biased judgment to get
5306 the best of both. It *does* need testing.
5308 Some of the changes are general, *not* mips-specific.
5311 Didn't believe in little-endian bit order.
5312 There are still inconsistencies about whether flags
5313 like BITS_BIG_ENDIAN are integer (#if ...) or
5314 boolean (#ifdef ...). I tried to paper over them.
5316 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5317 Moved some misc_function code that was common to
5318 {dbx,coff,mips}read.c to symtab.c.
5319 In the process, I think I cleaned things up a bit.
5320 At the same time, moved obsavestring and obconcat to symtab.c.
5323 Removed obsolete condense_addl_misc_bunches (use
5324 condense_misc_bunches(1) instead).
5327 Needed to include <sys/dir>, at least on DECstations.
5329 valops.c, mips-tdep.c, tm-mips.h:
5330 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5331 conventions (when STACK_ALIGN is insufficient).
5332 Needed on mips, where doubles need 8-byte alignment,
5333 but ints only need 4.
5336 Removed cruft that was not being used.
5337 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5340 Print $ before register-names (I think that makes things a little
5342 Never print two instructions, even if one delays.
5343 Removed hex-disassemble set_cmd. (This is not mips-specific,
5344 so I think the argument is whether it is generally worthwhile or not.
5345 I'm inclined to think not, given how easy it is to
5346 convert between radixes in gdb.)
5349 This is basically Alessando's code.
5350 It doesn't use obstacks; I changed it to use obstacks
5351 in a few minor places where using malloc causes a
5352 memory leak. (Probably, more places could/should be changed.)
5353 I added record_misc_function where it was missing.
5354 In symbol_file_command and add_file_command, I tried
5355 to make the code consistent with more recent versions.
5356 Minor sylistic changes in parse_procedure.
5357 Make a .gdbinfo. psuedo-symbol point back to the real
5358 procedure symbol (using the isym field).
5361 This is basically from my port, but with a lot of details
5362 and a number of routines merged in from Alessando's version.
5363 I basically used my code "raw" backtrace (use heuristics
5364 from the actual code, rather than symbol table info) - though
5365 the idea is Alessandro's. I feel my code is a little cleaner
5366 here, particularly in being a little more flexible, such as being
5367 able to handle gcc-produced code (which it now can).
5368 It also doesn't do frame caching (which is not useful
5369 more recent gdb versions).
5370 I also used my code for push_/pop_dummy, more or less.
5371 I tried to incorporate AF's code for testing sigtramp
5372 while backtracing; I probably got it wrong.
5373 Added mips_print_register, which tries to scrunch as much
5374 information as possible on a screen...
5375 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5376 under mips-pinsn.c), I don't see anything mips-specific here,
5377 and I don't see it being all that useful anyway.
5380 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5381 Use more register names (rather than hard-cases numbers).
5383 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5385 * Hack up 3.90.11 changes:
5387 * Makefile.dist (depend): parameterize $(GCC).
5388 Add solib.c and solib.o.
5389 (readline): Fix vpath for both absolute or relative SRCDIR.
5391 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5392 Also, let the part I didn't understand at least compile so
5393 I can test the rest. FIXME.
5395 * dbxread.c: Fix thinko using strcmp.
5396 (init_psymbol_list): declare static.
5397 (partial_symbol_file_open): Comment cleanups better, avoid
5398 cleaning up the string table since the caller will do that.
5399 Move the stat for mod time into symbol_file_command, temporarily.
5400 (There should be a mod time for each symbol file, eventually,
5401 to control its rereading. FIXME.)
5403 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5404 SunOS, which gives error for shared libs otherwise. (From
5405 Schaefer, probably FIXME needs work for portability.)
5407 * solib.c: Move #include "param.h" to work.
5408 Lowercase all the Uppercase Letters In the Messages.
5409 (find_solib): Clean up inferior_so_name for debug printouts.
5410 Allow no argument, to mean all shared libraries.
5412 * symmisc.c: include param.h to get CLEAR_SOLIB.
5414 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5416 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5417 to 3.90.11. ChangeLog entries below are from this.
5419 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5423 * Makefile.dist (HFILES): Add tm-sunos.h.
5425 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5429 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5431 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5433 * sparc-opcode.h Added single-operand version of rett.
5435 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5437 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5438 Put parens around gcc_p in expansion.
5440 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5442 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5444 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5446 * Changes for Sun shared libraries:
5447 blockframe.c (find_pc_partial_function): If a non-text symbol
5448 is found, set *address = pc - FUNCTION_START_OFFSET.
5449 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5450 Disable breakpoints instead of giving an error.
5451 source.c (select_source_symtab): Initialize cs_pst.
5452 symmisc.c: Call CLEAR_SOLIB if defined.
5453 symtab.h: Make text{low,high} CORE_ADDR not int.
5454 (psymtab): New field addr.
5456 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5457 (record_misc_function): Give correct type for N_DATA symbols.
5458 (condense_misc_bunches): do "misc_function_count = j" regardless
5460 Take code which is shared between symbol_file_command and
5461 add_file_command and put it into partial_symbol_file_{open,read}.
5462 Split add_file_command into add_file_command and add_file.
5463 Make psymtab_to_symtab read in the string table if the file
5465 Two new parameters to read_dbx_symtab and start_psymtab.
5466 tm-sunos.h: New file.
5468 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5470 * infcmd.c: Change cont_command to continue_command and "cont"
5473 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5475 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5477 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5479 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5480 size 1,2,4,8 rather than size < 8.
5482 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5483 as necessary, not just once.
5485 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5487 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5489 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5491 * tm-news.h: Add CALL_DUMMY_*.
5493 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5495 * config.gdb: In list_host, list_target, use ${i}, not $i.
5497 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5499 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5501 * sparc-opcode.h: Change all store floating-point state register
5502 instructions to have the right match & lose fields.
5504 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5506 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5508 config.gdb: If srcdir != ., create readline directory and
5509 copy a makefile into it.
5511 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5512 consistency with POSIX.
5514 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5515 when we exit its exp_valid_block.
5517 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5519 * Makefile.dist: Bump version to 3.91.3.
5521 * Clean up handling of breakpoint commands (somewhat).
5522 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5524 inferior.h: Add breakpoint_proceeded to inferior status struct
5525 and globals; save it and restore it.
5526 (clear_breakpoint_commands): Cleanup, remove old #define.
5528 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5529 (save_inferior_status, restore_inferior_status): handle it also.
5530 (proceed): Remove earlier code that set breakpoint_proceeded.
5531 It is now set only in clear_proceed_status.
5532 (clear_proceed_status): Cleanup, use bpstat_clear rather
5533 than clear_breakpoint_commands. No callers need the stop_bpstat
5534 between clear_proceed_status and proceed.
5536 infcmd.c: Add breakpoint_proceeded definition and comment.
5537 (cont_command, jump_command, signal_command): Move call to
5538 clear_proceed_status right next to call to proceed.
5540 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5541 caller's argument while running down the chain of breakpoints.
5542 Use new variable "breakpoint_proceeded" to determine when
5543 a command that it executes moves the inferior past the
5545 (bpstat_clear): Handle NULL argument.
5546 (bpstat_clear_actions): Avoid useless call to
5547 breakpoint_auto_delete.
5548 (delete_breakpoint): Clean up bpstat's that are pointing to
5549 the deleted breakpoint from the stop_bpstat chain.
5550 (breakpoint_auto_delete): Simplify.
5552 * Clean up handling of EOF, error on stdin, etc. This was
5553 prompted by a network problem that caused gdb to go into an
5554 infinite loop filling up its malloc'd memory.
5556 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5557 not clear_breakpoints_commands, which is now gone.
5558 (main): If command_loop returns (e.g. from EOF on stdin), do
5559 a quit_command (looping back to command_loop if quit_command
5560 doesn't really quit).
5561 (command_loop): check result from command_line_input and
5562 exit if it returns NULL, rather than passing the NULL to
5564 (gdb_readline): Free malloc'd result space before returning
5567 * utils.c (query): Handle C-d to mean "yes", just as if the
5568 input was not a terminal. Also avoid infinite loop if EOF
5569 occurs in mid-input-line before newline. This allows
5570 query to be used at EOF on stdin with reasonable results.
5572 * infrun.c (proceed): Set breakpoint_proceeded.
5574 * values.c (value_as_long): Avoid infinite recursion for enums.
5575 (_initialize_values): Fix typo in help msg (kingdon).
5577 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5578 RL_LIB for linking. This allows -lreadline for linking
5579 and nothing for dependencies, once readline is a real library.
5581 * config.gdb: Jim Kingdon: give useful error message if the
5582 host or target type is not recognized.
5584 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5585 it just defines it. Dumb, but deal with it.
5587 * Jim Kingdon suggests:
5588 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5590 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5592 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5594 * Clean up Bothner's changes.
5596 * blockframe.c (clear_pc_function_cache): New function.
5597 * blockframe.c: remake cache_pc_function_* static.
5598 * dbxread.c (symbol_file_command): remove references to
5599 cache_pc_function_* variables.
5600 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5601 * printcmd.c: Avoid kludging a global variable (addressprint)
5602 to avoid printing the address of a string twice. Instead,
5603 pass the format letter 's' down low enough that it can be seen
5604 to avoid this problem.
5605 (print_formatted): Pass format arg to value_print.
5606 (restore_addressprint): Remove function.
5607 (do_examine): Avoid hacking addressprint, cleanups and such.
5608 (print_frame_args): Add a comment to a Bothner change.
5609 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5610 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5611 to wipe out the values cached in blockframe.c.
5612 * symtab.c (find_method): Add comment saying how big you must
5613 allocate to be "big enough". Per being terse again.
5614 * valprint.c (val_print): Handle format letter "s" to print
5615 strings without addresses. Add comment to vtbl printing code
5616 which casts with wild abandon. Rearrange reference-printing
5618 @0xaddr: value (print w/addressprint)
5619 value (print w/~addressprint)
5620 @0xaddr (parameter lists w/addressprint)
5621 or nothing (parameter lists w/o addressprint)
5623 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5625 * Merge more changes from Per Bothner:
5627 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5628 annoying) that I tried to improve it. Here are my suggestions.
5630 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5633 Do automatic de-reference when taking the address of a reference.
5635 Don't deref_ref when printing parameter lists.
5637 More attempts at treating refernences properly.
5639 In val_print, if deref_ref==0, don't print dangling " = ".
5641 Add COERCE_REF macro, which de-references an REF.
5643 * Merge changes from Per Bothner:
5645 * Fixed (Sony news)-specific configuration problems.
5646 * Fixed other problems with using vanilla pcc and libc (enum problems;
5647 assumption that vsprintf exists).
5648 * Some major speed-ups (finc_pc_partial_function now caches a match;
5649 parsing avoids duplicate symbol_lookup calls).
5650 * Changed handling of baseclasses (no longer use baseclasses field
5651 of struct type, use the first n_baseclasses fields instead).
5652 * Various minor changes/fixes, most C++-related.
5655 Cache the most previous match from find_pc_partial_function.
5656 (Save both low and high ends of matching function's pc range.)
5657 This speeds up the loop of infrun.c:wait_for_inferior quite
5658 a bit, and makes step/next commands much zippier.
5660 Added an enum->int cast (otherwise, some compilers barf).
5662 No longer set baseclass offset to 0, since multiple
5663 inheritance now mostly works.
5664 Added a number of casts, to shut up compiler warnings
5665 (after stabs where made enums, not ints).
5666 When discarding a symbol table (in symbol_file_command),
5667 must clear the cache introduced in blockframe.c.
5668 Don't convert $vtbl_ptr_type to vtbl any more.
5669 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5670 Mask off sign bit emitted by g++ for virtual table offset.
5671 Set voffset to -1 (not 1) for static member functions.
5673 Changed parsing/lexing of names to avoid doing symbol lookup twice
5674 (once when lexing to determine symbol class, once for real).
5675 Now only call symbol_lookup once. Fields of 'this' win especially big.
5677 Subpress printing addr twice in the case of 'x/s addr'.
5679 lookup_basetype_type is no longer used.
5680 Add find_methods as recursive helper function to decode_line_1.
5681 This allows multiple inheritance to work.
5682 Also, once one or more matches has been found, do not look in
5683 base-classes. (Baseclass methods would be overridden, anyway.)
5685 Removed baseclasses array in struct type.
5686 Instead of using baseclasses[i], use fields[i-1].
5687 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5688 Changed sign convention of voffset (previous was inconsistent).
5690 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5692 Used to assume existence of vsprintf. Re-written to not need it
5693 if HAVE_VPRINTF is undefined.
5695 typecmp was too pessimistic. Made it less so.
5697 Don't print space after address.
5698 If vtable points to a misc symbol (with 0 offset), print it,
5699 since that indicates the actual class of the object.
5700 Changed ype_print_derivation_info to use new inheritance
5701 scheme (without baseclasses vector).
5703 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5704 Also, changes needed because TYPE_BASECLASSES were removed.
5706 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5708 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5711 If there is no path set, and the symbols don't indicate what directory
5712 a file was compiled in, look in the current directory. But either
5713 a path or a known compilation directory will prevent this.
5716 Three independent bug fixes:
5717 * Remove the #if 0 block that breaks some stuff.
5718 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5719 adapt gdb to either SunOS 4.0.* or 4.1.
5720 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5723 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5726 (type_print) Demangle the name being printed.
5727 (type_print_base) Handle botched demangling without coredump (tiemann).
5730 (check_stub_method): Document routine.
5731 (tiemann) fix bug for no-arg functions
5732 Avoid clobbering beyond end of malloc'd storage.
5733 Terminate the argument list properly.
5735 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5737 * Changes merged by John Gilmore:
5740 In breakpoint_1, use new print_address_symbolic instead
5741 of find_pc_partial_function. (This forces use of assembler-level
5742 addresses, and avoids misleading non-mangled source-level names.)
5744 Generalize ansi argument such that -1 means skip arglist totally.
5745 Removed global variable print_ansi_qualifiers (which made
5746 code non-reentrant), in favor of extra explicit arguments
5747 to internal routines.
5749 Add new helper function print_address_symbolic.
5750 Use find_pc_misc_function instead of find_pc_partial_function
5751 (since we want assembler-level symbols here).
5753 Print unknown function as just "f (...)", not "f (...) (...)".
5754 Use new fputs_demangled explicitly.
5756 Fixed a typing violation (problem: value.h cannot be imported
5757 without renaming many variable in this file).
5758 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5759 decode_line_1: Moved forward some never-reached code.
5760 Made decode_line_2 skip function prologues correctly.
5762 fputs_filtered should not demangle by default.
5763 Add new fputs_demangled to demangle on demand..
5765 Change value_struct_elt to use value_primitive_field (using recursive
5766 utility function search_struct_field). This allows foo.bar to work
5767 for multiple inheritance (so far only for data fields).
5768 Change check_field in the same way (recursive helper function
5769 to support multiple inheritance).
5770 (Note: there are more of these problems that I haven't fixed.
5771 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5772 value_of_this: 'this' symbol name is now just "this", note "$this".
5774 Don't print static members.
5775 Avoid printing "members of <type>" if there are none.
5776 Simplified type_print_derivation_info by merging duplicate code.
5777 Remove useless blank lines in type_print_base (ptype command).
5779 Added declaration of new routine value_primitive_field.
5781 Added value_primitive_field which is generalized version of
5782 value_field that can handle multiple inheritance (non-zero offsets etc).
5783 Re-implemented value_field to call value_primitive_field.
5785 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
5787 * infcmd.c -- insert else to avoid 'delete env' coredump when you
5788 delete the whole environment. Karl Berry reported the bug.
5789 * source.c - fix openp to avoid //'s in filenames, which
5790 trigger an Emacs bug causing it to not be able to find files
5791 when running gdb in a window.
5792 * dbxread.c - zap the #if 0 that botches the add-file code.
5793 It seems to work a lot better without all the code commented out.
5795 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
5797 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
5800 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
5802 * Makefile - added a ${CFLAGS} to a couple of entries,
5803 added remote-sa.sparc.c
5804 * added remote.sa-sparc.c, a modification of remote.c
5805 which conducts a dialog directly with the SparcStation prom.
5806 * breakpoint.c, infrun.c, sparcdep.c added
5807 remote_insert_breakpoint(), and remote_remove_breakpoint()
5808 to breakpoint.c instead of directly writing breakpoint instructions.
5809 * sparcdep.c on remote_debugging,there is no need
5810 to remove signle step breakpoint instructions.
5811 * main.c added "-epoch" flag and "int epoch_interface" to main.c
5813 * printcmd.c - epoch interface sends lisp expressions to open up
5814 epoch windows on inspection.
5815 * valprint.c - added arrayprint, and addressprint and made adding
5816 format controls easier
5817 * wait.h added a couple of undef's because we were getting
5818 complaints about WSTOPSIG and WTERMSIG begin redefined.
5821 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
5823 * symtab.c (decode_line_1): Add support for handling method stubs
5824 in the type information.
5826 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
5828 * values.c (baseclass_addr): Run loop from INDEX+1 to
5829 N_BASECLASSES; otherwise, we can still get into a loop.
5830 @@ This should be restructured to use a cleaner search strategy.
5832 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
5834 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
5835 abbreviation "Tt" for tags which have the same name as their
5838 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
5840 * symtab.c (list_symbols): add ability to set breakpoints on all
5841 the functions which match a particular regular expression.
5843 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
5845 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
5846 should print ANSI qualifiers (such as `const' and `volatile').
5847 All callers changed to call with ANSI == 1, except from
5848 `check_method_stub', which uses old-style syntax.
5850 * symseg.h (struct fn_field): Remove unneccessary `args' field.
5851 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
5853 * values.c (check_stub_method): New function.
5855 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
5857 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
5858 * valprint (type_print_base): Ditto.
5860 * symtab.c (gdb_mangle_typename): New function.
5862 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
5864 * breakpoint.c (catch_command): New function. Provides a
5865 mechanism to set breakpoints based on catch clauses.
5866 (disable_catch): Similar, but disables breakpoints on catch
5868 (delete_catch): Similar, but deleted breakpoints on catch clauses.
5870 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
5872 * blockframe.c (blockvector_for_pc): New function.
5873 * blockframe.c (block_for_pc): Changed to call
5874 `blockvector_for_pc' and get the block itself.
5876 * stack.c (catch_info): New function. Prints info about
5877 exceptions which can be caught in the current frame.
5878 * stack.c (print_frame_label_vars): New function. Similar to
5879 `print_frame_local_vars'.
5880 * stack.c (print_block_frame_labels): Prints out labels that are
5881 defined in this frame. These labels are exceptions that can be
5884 * dbxread.c: Updated to handle N_CATCH symtab types.
5886 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
5888 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
5889 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
5890 when printing the type.
5892 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
5894 * valprint.c (val_print): Use `baseclass_addr' to access the
5895 baseclasses pointed to via the derived class object at VALADDR.
5897 * values.c (baseclass_addr): New function. Casts derived pointers
5898 to baseclass pointers taking virtual baseclasses and multiple
5899 inheritance into account.
5901 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5905 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5907 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
5908 exp_valid_block field correctly.
5910 * infrun.c (wait_for_inferior): When checking "don't even think
5911 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
5912 also check step_resume_breakpoint.
5913 Insert breakpoints and continue (not step) if
5914 step_resume_break_address != NULL, even if another_trap.
5915 If trap_expected and we enter sigtramp, then set up a
5917 If trap_expected is set when we hit the step_resume_break,
5919 When calling resume and trap_expected says tell resume to step
5920 (2 places), also check step_resume_break_address.
5922 * infrun.c (wait_for_inferior): Don't set
5923 prev_{pc,sp,func_{start,name}} before calling wait ().
5924 Do set them after exiting loop.
5925 Move their declarations outside functions.
5926 (start_inferior): Initialize them.
5928 Thu May 3 00:15:11 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5930 * infrun.c (wait_for_inferior, after check for trap_expected > 1):
5931 Restore old code which distinguishes between trap_expected and
5932 running_in_shell, just make the latter take any non-TRAP signal,
5935 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
5937 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.
5938 xconfig/3b1 (CC,PINSN_CC): Define.
5940 * xconfig/altos, altos-dep.c: Rename altos-dep.c to altos-xdep.c.
5944 * breakpoint.c (bpstat_stop_status),
5945 infrun.c (wait_for_inferior) [SHIFT_INST_REGS]: New code.
5947 * param.h, tm-88k.h: Define ADDR_BITS_*.
5948 infcmd.c (jump_command, read_pc), infrun.c (wait_for_inferior),
5949 printcmd.c (do_one_display): Use them.
5951 * utils.c: Split #ifdef USG into a USG_UTILS and a QUEUE_MISSING.
5952 xm-88k.h: Define USG_UTILS.
5954 Wed May 2 00:05:33 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5956 * printcmd.c (printf_command) [__INT_VARARGS_H]: New code.
