1 Fri Nov 1 11:05:47 1991 John Gilmore (gnu at cygnus.com)
3 * mipsread.c (read_mips_symtab, read_the_mips_symtab): Use real
4 filename with error messages.
5 * stack.c (frame_select_command): Rename to select_frame_command
6 to avoid "fr" and "fra" having nonunique completions.
7 * symfile.c (sort_symtab_syms): Ignore sort of zero symtab *.
8 (symfile_init): Print file format name when unable to handle it.
9 (free_named_symtabs): Use BLOCKVECTOR rather than obsolete BLOCKLIST.
10 * symmisc.c (free_symtab): Only free linetable if nonzero.
11 * symtab.h: Remove obsolete BLOCKLIST macros.
13 Thu Oct 31 18:12:43 1991 Stu Grossman (grossman at cygnus.com)
15 * infrun.c (wait_for_inferior): another stepi/nexti fix. Ensure
16 that stop_step is 1 at bottom of main loop. I don't know why this
17 needs to be done, but it helps me sleep better at night.
19 Sun Oct 27 18:18:39 1991 Stu Grossman (grossman at cygnus.com)
21 * main.c (initialize_history): Read history after reading all
24 Sun Oct 27 14:09:25 1991 John Gilmore (gnu at cygnus.com)
26 * buildsym.c: Break out initial malloc sizes.
27 (record_line): Record directly in a subfile. Alloc on demand.
28 (compare_line_numbers): Add from xcoffread.c.
29 (end_symtab): New params say whether to sort pendings and
30 linetable. Patch block stabs if defined. Shrink linetable before
31 allocating the symtab.
32 * buildsym.h: Delete line_vector* and prev_line_number. Add
33 global_stabs and file_stabs for xcoffread.
34 * dbxread.c (start_subfile): Move to buildsym. Change above calls.
35 * symtab.h: LINETABLE(symtab) can now be null. Zap LINELIST.
36 * symmisc.c, symtab.c: Cope with null LINETABLEs.
38 * blockframe.c: Pass fromleaf to INIT_EXTRA_FRAME_INFO.
39 * tm-29k.h, tm-88k.h, tm-i960.h, tm-irix3.h, tm-mips.h, tm-pyr.h,
40 tm-sparc.h: Accept fromleaf parameter.
41 * c-exp.y (yyerror): Pass error message if given.
42 * configure.in: Add rs6000 host and target.
43 * inflow.c (new_tty): O_NOCTTY kludge for RS/6000.
44 * symfile.h (entry_point): Add.
46 Sat Oct 26 00:16:32 1991 John Gilmore (gnu at cygus.com)
48 * buildsym.c: New file. Breaks out symbol-table-building routines
49 from dbxread.c, so they can be shared with xcoffread.c.
50 * buildsym.h: New file. Declarations for buildsym.c users.
51 * dbxread.c: Remove large chunks into buildsym.c.
52 * Makefile.in: Add buildsym.c and buildsym.h.
54 * symfile.c (syms_from_bfd): New routine.
55 (add_symbol_file): Call it to do the real work.
56 (syms_from_bfd): Initialize entry_point before calling symfile_init.
57 * symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
58 Avoid declaring or setting entry_point (symfile.h & symfile.c cope).
60 Fri Oct 25 18:59:32 1991 Per Bothner (bothner at cygnus.com)
62 Various fixes to improve g++ debugging.
63 * symtab.h: Add is_const and is_volatile flags for each method.
64 These are bit fields - take their space from voffset,
65 which shrinks to 30 bits. Since voffset is now a bitfield,
66 make it unsigned for portability. This changes its interpretation
67 slightly: Static methods now have voffset 1 instead of -1,
68 and virtual offsets start at 2, not 1.
69 * symtab.c: Renamed gdb_mangle_typename to gdb_mangle_name,
70 since it now returns an entire magled method name, not just
71 the type part. This avoids some duplication.
72 It also allows us to correctly mangle const and volatile
73 methods (using the new is_const and is_volatile bit fields
75 * valprint.c (type_print_base), values.c (check_stub_method):
76 Simplify by using new gdb_mangle_name.
77 * values.c (value_headof): Fix to correctly handle single
78 inheritance (actually two fixes, either of which suffices).
79 * dbxread.c (read_struct_type): Handle const and volatile
81 * dbxread.c (read_struct_type): Yet one more place where
82 we must handle '\\' continuations.
83 * valprint.c (vtbl_ptr_name): Add final '\0'.
85 Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com)
87 * tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of
88 short return values for sparc and 68k. Patch from Paul Eggert.
90 * coffread.c, coredep.c, i386-xdep.c: install patches for
91 SysV/386 3.2 from Mauro DePalma.
93 Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
95 * core.c (core_file_info), exec.c (exec_file_info): Print file
96 type. Use printf_filtered.
98 * valops.c (value_fetch_lazy): Avoid 0-length fetches.
100 Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
102 * dwarfread.c: Add casts to remove compiler warnings.
104 * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
105 tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
106 tm-sun3.h: Remove locally duplicated code for calling functions
107 in the inferior. The only differences were in the specific trap
108 vectors used and whether or not an fpu was present. These are
109 now handled by appropriate definitions of BPT_VECTOR and
110 HAVE_68881 respectively. Other minor obvious cleanups.
112 * valops.c: Correct a minor misspelling.
114 * utils.c: Remove local BSD/USG hacks that are now in libiberty.
116 * dwarfread.c: Remove prototype for dwarfwarn. Does not work
119 Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
121 * stack.c (frame_command): Always print. Use new
122 frame_select_command to select a frame without printing.
124 * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
126 Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
128 * dwarfread.c: New file for DWARF debugging format support.
130 * elfread.c: New file for ELF object file format support.
132 * procfs.c: New file for SVR4 /proc (process file system) support.
134 * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
137 * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
139 * xm-m68k.h: New file for host machines with m68k cpu.
141 * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
142 Add elfread.o and dwarfread.o to OBS.
144 * symfile.h: Add "elf" to list of supported formats in comment.
146 * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
147 types to gdb, builtin_type_long_double, builtin_type_complex, and
148 builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
149 TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
150 TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
151 TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
152 types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
154 * infrun.c: When using SVR4 /proc interface instead of ptrace(),
155 call proc_set_exec_trap() to setup child to stop at first instruction.
157 * inftarg.c: When using SVR4 /proc interface, call proc_wait()
160 * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
161 supply_fpregset(), and fill_fpregset(), which are machine
162 dependent support routines for SVR4 /proc interface.
164 * utils.c: Add warning_setup() and warning(). Warning() behaves
165 the same as error() except that it returns normally rather than
166 jumping back to command level. Modules that don't want to call
167 warning() for some reason, but want to produce their own warnings,
168 can call warning_setup() to ensure compatibility with the way
169 warning() and error() deal with the terminal.
171 * symtab.c: Make internal errors produce more useful messages.
173 * tm-68k.h: Move code that is duplicated in almost every single
174 m68k based machine's configuration files to this common file.
175 Duplications in the configuration files still need to be removed
178 * infrun.c (child_create_inferior): System V versions must call
179 setpgrp() with no arguments, to comply with prototyping typically
182 * munch: Add support for SVR4 style nm output.
184 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
185 file specific fields from the partial symbol table structure and
186 replace them with a pointer to private data for each different
187 flavor of object file reader to initialize appropriately.
189 Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
191 * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
194 * mipsread.c (fixup_undef_type): New function. If a struct /
195 union / enum is defined in a header file but nowhere else used,
196 (by typedefing, pointer referencing or declaration) the mipsread code
197 builds the complete tree for the structure but leaves its code as
198 TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
199 Guess its type based on the details of the members.
201 Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
203 * infrun.c (wait_for_inferior): Check return value from
206 Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
208 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
209 by my last edit to this routine.
211 Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
213 * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
214 FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
215 the values before putting them into the dummy code. (From Peter
218 Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
220 * configure.in: added ebmon target.
222 Wed Oct 16 22:49:58 1991 John Gilmore (gnu at cygnus.com)
226 * Makefile.in: Roll VERSION to 4.2.
227 * README, TODO, WHATS.NEW: Update.
229 * core.c (core_open): Improve error message for bad file.
230 Pass .reg virtual memory address to fetch_core_registers to help
231 it find the registers in the core-file header.
232 * coredep.c (fetch_core_registers): Take new argument, use it,
233 and pass it to register_addr to locate the block of registers.
234 * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
236 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
237 Sequent N_FN_SEQ like everybody else's N_FN.
239 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
240 * tm-i386v.h: #endif guck.
241 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
242 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
243 * xconfig/tahoe: Add REGEX, which seems to be missing.
245 * coredep.c: Add <sys/types.h> for SCOnix.
246 * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file.
247 * printcmd.c (print_formatted): Flush output before disassembly.
249 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
251 * doc/refcard.tex (sec "Working Files"): consistent metavars and
252 other improvements, due to comments by François Pinard
253 (pinard@iro.umontreal.ca)
255 * doc/gdb.texinfo (appendix "Installing GDB"): changes in
256 configure, and improvenets related to Pinard's refcard comments
258 Tue Oct 15 08:45:12 1991 John Gilmore (gnu at cygnus.com)
260 Changes from Fred Fish:
261 * tm-68k.h (FPI_REGNUM): Add.
262 * infrun.c (child_create_inferior): flush stdout and stderr

265 * inflow.c: Handle TIOCGLTC_BROKEN for Amiga.
268 * values.c (show_convenience): Use printf_filtered.

275 * i387-tdep.c (double_to_i387): Fix typo for double_to_ieee_extended.
276 * utils.c (_initialize_utils): If !ISATTY, don't paginate.
277 * configure.in, tconfig/decstation, xconfig/decstation: Rename
278 dec3100 to decstation.
280 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)
282 * doc/gdb.texinfo: Catch up to changes recorded here in ChangeLog
283 (nodes Continuing and Stepping; Memory; Targets) clarifications

288 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move
289 REGISTER_U_ADDR to corresponding xm- file. Sugg. by Peter Schauer.
291 * symmisc.c (print_partial_symtabs): Add printpsyms debug cmd.

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

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

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

447 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
451 * Makefile.in (VERSION): Set to 4.1.
452 * language.c (set_language_command): Print useful help message,
453 and restore the language string after giving help.
454 * valprint.c (typedef_print): Print typedef in C or M2.
455 * symtab.c (list_symbols): Use it.
456 * main.c (main): Avoid any output before (gdb) prompt when -q.
457 * language.c (set_language_command): Handle errors by restoring
458 the language string to its current state (fix from A. Beers).
459 * doc/gdbint.texinfo: Roll in information from README. Rearrange
460 "how to install" and "how to print the doc" stuff so it drops
462 * configure.in: Rename rtpc CPU to romp to match config.sub.
463 * README, WHATS.NEW, TODO: Update for gdb-4.1.
465 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
467 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
468 autoloading shared libs, copyright etc on GDB startup, clean up $_
469 and $__ index refs, set/show listsize and related updates to list
470 cmd. New host/target configs.
472 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
474 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
475 from main Makefile.in version definition
476 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
478 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
480 * doc/gdb.texinfo: merge new language-switching and lang-specific
483 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
485 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
486 compilers (which may lack stddef.h).
488 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
490 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
491 N_WARNING are the same except for the N_EXT bit, so just use their
492 values alone, rather than OR-ing them with N_EXT.
494 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
496 * mipsread.c (parse_lines): Deal with negative extended line
499 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
500 global symbol conflicts.
502 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
504 * .gdbinit: Move 'set complaints' to top, so it runs even in
505 case we aren't debugging GDB.
506 * language.c (_initialize_language): Fix type check and range
507 check documentation strings.
508 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
509 language.c can use it. (Though language.c should really not be
510 handling warnings/errors the way it does, FIXME.)
511 * symtab.c (lookup_primitive_type): const lint.
513 Bugfix from Peter Schauer:
514 * source.c (lines_to_list): Make signed, to avoid comparison
515 going unsigned and complaining that -3 is too high for 21 lines.
516 * stack.c (lines_to_list): Ditto.
518 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
520 * Makefile.in (HFILES): Add minimon.h.
521 (VERSION): Roll version number to 4.0.95.
522 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
523 New rules for building distributions. Normal distribution
524 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
525 one level up from here; it calls make-proto-gdb.dir to build a
526 directory `proto-gdb' which is an image of the release. The old
527 `gdb.tar.Z' rule still works too.
528 * config.sub, configure: Roll in latest from ..
530 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
532 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
533 new-target, and new-config chapters; fix minor typos; come closer
534 to usual GNU markup conventions for @file @samp @code @var.
536 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
538 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
539 * mipsread.c (parse_partial_symbols): Enter the name of all
540 structs/unions... into the psymtab so we can access them if the
541 symtab is not read in.
542 * mips-tdep.c: Remove some unneeded #includes.
543 * xconfig/dec3100: Add HAVE_STRSTR.
545 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
547 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
548 * c-exp.y, m2-exp.y: Lint.
549 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
550 * valprint.c (val_print_fields): Check for stub type.
551 * mipsread.c (_initialize_mipsread): Avoid using
552 builtin_type_void at initialize time.
553 (mipscoff_symfile_read): use it now.
555 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)

580 (process_coff_symbol): #if 0'd for functions and params as above.
581 (read_enum_type): Recognize Modula-2 BOOLEAN.
582 * symtab.c (add_param_to_type): #if 0'd function to add a

654 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
656 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
657 entries are enclosed herein. Not all of these changes
658 have been merged into the master GDB sources -- check the
659 ChangeLog above here for the merge log.
661 Mon Jun 3 17:05:45 EDT 1991
663 m2-exp.y Created. Tested outside of GDB for a few days. Proper
664 operators were added, C specific operators and tokens
665 removed. yylex() revamped to some extent. Still things
666 missing from the grammar, such as sets.
667 Tested for two weeks in GDB v3.5.
669 Tue Jun 11 17:23:48 EDT 1991
671 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
672 so they are built-in. Sort of a hack.
674 Fri Jun 14 12:53:51 EDT 1991
676 m2-exp.y Added range checking for numeric constants. Any numeric
677 constant is assumed to be of builtin type INTEGER unless:
678 (1) it is octal or hexadecimal, in which case it is a
679 CARDINAL; (2) it is too big to fit into an INTEGER, in
680 which case it is a CARDINAL.
681 eval.c Added simple range checking for +, -, and * on integers.
682 Doesn't work very well for *, since 6 * 1,000,000,000 =
683 1,705,032,704, which fails the simple test of result >=
684 first_operand, no matter in what order the operands are.
686 Tue Jun 18 14:11:30 EDT 1991
688 Broke the parser into parts, one containing the C grammar and the other
689 containing code to be shared by all of the grammars.
691 The following files no longer exist:
696 The following files were added:
698 c-exp.y (The C grammar)
699 m2-exp.y (The Modula-2 grammar)
700 parser-code.c (Code that is shared by the above grammar)
704 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
705 now necessary to use the Bison compiler compiler, since it
706 will generate function/variable prefixes other than yy.
708 Tue Jun 18 16:47:49 EDT 1991
710 symtab.[ch] Added the external variable working_lang, than holds the
711 value of the current working language.
712 Added the ennumerated type language_mode, with the values
713 language_auto and language_manual, the former meaning that
714 GDB sets working_lang as needed, and the latter meaning
715 that the value of working_lang is totally under user
717 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
718 REAL, BOOLEAN and CHAR. Also added the type codes
719 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
720 utils.c Added set_language_command and show_language_command to
721 implement the GDB support commands "set language" and
723 expression.h A number of identifiers were added to the type exp_opcode
724 to facilitate Modula-2 builtin functions, integer
725 division, and array indexing.
727 Wed Jun 19 13:25:58 EDT 1991
729 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
730 if the language specified by working_lang requires the use
731 of strict typing of expressions. Eventually, even this
732 will be able to be changed by the user.
733 Added the macro RANGE_CHECK, which evaluates to non-zero
734 if the language specified by working_lang requires the
735 checking of a value against the domain of its type.
736 Eventually, even this will be able to be changed by the
738 language.[ch] Predicates involving types (simple_type, ordered_type,
739 same_type, integral_type, numeric_type, character_type,
740 boolean_type, float_type) are added. These predicates are
741 based on the current value of working_lang, and are handy
744 Wed Jun 19 15:39:34 EDT 1991
746 eval.c Added the function type_array_rank which computes the rank
748 valarith.c Added the funtion value_bool, which when given a integer
749 value.h value (ie. struct value *) as an argument, it returns a
750 boolean value (ie. struct value *) true if that integer
751 is non-zero, and a boolean value false otherwise.
752 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
753 will print out properly.
755 Wed Jun 19 16:36:34 EDT 1991
757 valops.c Added the function value_capitalize, which returns it
758 value.h argument capitalized if its argument is a lowercase
759 letter, or the argument unchanged if its argument is not a
761 valarith.c Added the function range_check_p, which returns non-zero
762 value.h if its value argument is between the integral bounds upper
764 Added the function range_check_enum_p, which makes sure
765 that its value argument is a valid member of the domain of
767 Added the function range_check_range_p, which makes sure
768 its value argument lies between the upper and lower bounds
769 of its type argument, which must be a ranged type.
770 Added the function check_array_index, which range and type
771 checks an index of an array.
772 Added the function value_multi_subscript, which computes
773 array[idx1,idx2...idxN], given a value array and an array
774 of values representing indicies.
775 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
776 unpack_long to work with TYPE_CODE_BOOL and
779 Wed Jun 19 18:04:08 EDT 1991
781 symtab.c Stored pervasive types in a structure and make
782 lookup_pervasive_type() a lookup function that was based
783 on working_lang. If lookup_pervasive_type() returned
784 non-zero, then that value was returned (a fix, since
785 before it simply wouldn't return the pervasive type.)
786 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
787 non-zero if the language specified by working_lang means
788 "conversion" when it says "cast".
789 valops.c Added the function value_real_cast(), which performs a
790 value.h *cast*, not a *conversion*, which is what value_cast()
791 does when it can. In particular,
792 value_cast(<float_type>,4) = 4.0, while
793 value_real_cast(<float_type>,4) = some mess.
794 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
795 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
796 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
797 and MIN on integral types. *NOTE*: These are currently
798 hardcoded to work only if there are 8 bits per storage
800 eval.c Made logical functions call value_bool to return a
801 properly typed boolean value, based on working_lang.
803 Thu Jun 20 11:55:27 EDT 1991
805 valprint.c Types now print out in a Modula-2 fashion. This works for
806 the cases when the type is printed out step-by-step, that
807 is, it doesn't work when the name of a structured type
808 (which includes the keyword "struct", etc.) is simply
810 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
811 since type specifications in C and Modula-2 are very
812 different. The C printing of a type is very recursive,
813 whereas in Modula-2 it is generally very simple. C has
814 type prefixes and suffixes, which have no real analogue in
815 Modula-2. Maybe type_print() should call a language
816 specific type printer. This is also advantageous if we
817 compile GDB to exclude some of the languages. We'll just
818 leave those functions out.
820 Thu Jun 20 16:57:10 EDT 1991
822 dbxread.c When reading the complete symbol table in (via
823 psymtab_to_symtab()), the number and types of function
824 arguments are added to a function type. define_symbol()
825 calls add_param_to_type() to accomplish this.
826 Assumption: when we come across a function definition
827 (N_FUN symbol with an 'f' or 'F' in the name), its
828 arguments will appear before another function definition.
829 When a function is found, a pointer to its type is placed
830 in the global in_function_type. Changes that
831 add_param_to_type() makes are to this global.
832 valprint.c The type of a function now includes (for Modula-2) the
833 types of its parameters.
834 eval.c Type checking and a check for the proper number of
835 arguments is now done for function calls. Not sure of the
836 impact this has on C++ member function yet.
838 Thu Jun 20 19:58:48 EDT 1991
840 valprint.c Rewrote the type printer. Broke it into two language
841 specific parts, adding the functions type_print_m2() and
843 An unfortunate consequence is this: if you debugging a C
844 program in Modula-2 mode (why?), info types does not work
845 well with regular expressions, since the types are printed
846 out in Modula-2 terminology, but stored in C terminology.
847 language.[ch] Added the functions new_type_last(), type_keyword(), and
848 type_sep() to aid in the printing of typedefs.
849 symtab.c Made the printing of typedefs as language independent as
850 possible through calls to new_type_last(), type_keyword(),
853 Fri Jun 21 11:50:26 EDT 1991
855 dbxread.c Check all incoming ennumerated types. If it looks like
856 Modula-2's BOOLEAN type, then change the type_code of the
857 type to TYPE_CODE_BOOL so we can process it as a boolean
859 valprint.c Replaced some of the 0x%x with calls to sprintf and
860 hexformat() in val_print().
861 language.[ch] Added the function hex_to_string(), which converts its
862 integral argument to a hexadecimal number (format is
863 language based) and returns the result as a string.
865 Mon Jun 24 12:25:07 EDT 1991
867 valprint.c Some functions call type_print_1() directly, instead of
868 value.h using type_print(), so they can specify where (column) to
869 print things. Since type_print() takes care of language
870 dependence, that needs to be called first. Added a
871 parameter depth to type_print() (so it is now like
872 type_print_1). Changed type_print to type_print_at, and
873 made type_print a macro that passes a depth argument of
875 symmisc.c Changed all calls to type_print_1 to calls to
877 Makefile.dist Made it possible to build GDB for a specific set of
878 depend languages. Do this by passing a definition for the macro
879 LANGS to make. LANGS should be a string containing a
880 space-separated list of language names (ie. LANGS="c m2").
881 The default is to build all languages. Note that grammar
882 files must follow the naming convention of <lang>-exp.y.
883 gdb.lang This holds the current value of the LANGS macro. It is
884 examined every time make is called, and is updated if
886 eval.c Added #ifdef _LANG_<lang> to these files.
887 expread.c Still need to add them to dbxread.c and coffread.c.
895 Mon Jun 24 16:33:11 EDT 1991
897 language.[ch] Added the functions hexformat_pre() and
898 hex_to_string_pre(), which take a prefix argument to
899 include in the format string. Thus, hexformat_pre("08") will
900 return "0x08x" (if the working language is language_c).
901 Made hexformat() and hex_to_string() calls to the above
902 with "" as the prefix argument.
904 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
905 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
906 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
907 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
908 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
909 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
910 valprint.c, vax-pinsn.c
912 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
913 calls to hexformat() and hex_to_string(). Format strings without
914 the leading "0x" were ignored.
916 depend Updated to take the above into account.
919 Tue Jun 25 15:27:18 EDT 1991
921 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
922 and type_check_t to keep track of the current state of
923 range and type checking.
924 main.c Added the variables range_mode, range_check, type_mode,
925 and type_check to record the current state of range and
926 type checking. Added initialization code to main().
927 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
931 Tue Jun 25 17:57:08 EDT 1991
933 dbxread.c process_one_symbol() updates the variable (enum language)
934 source_lang based on the extension of the filename
935 contained in the N_SO sybmol that started this symtab.
936 When end_symtab() is called, the value of source_lang is
937 put into the language field.
938 stack.c select_frame() sets working_lang (and possibly type_check
939 and range_check) to the language field of the symtab
940 associated with the frame that is selected if working_mode
941 is language_auto. If working_mode is language_manual, a
942 warning is printed and working_lang is not set.
943 language.c Added the function set_type_range(), which sets the value of
944 type_check and range_check (if their modes call for
945 automatic setting) based on the current value of
946 working_lang. A non-zero argument will cause the current
947 settings to be output.
950 Wed Jun 26 14:51:40 EDT 1991
952 eval.c Added range checks on assignment.
953 m2-exp.y Added the grammar for sets to the language. Currently,
954 these do not do anything except print an error message.
956 Wed Jun 26 17:01:04 EDT 1991
958 m2-exp.y Added the ability for parse_number() to parse negative
959 numbers. A global flag is set upon encountering a unary
960 minus. This was done to make, for example, 1 parse as a
961 CARDINAL, and not as an integer, per Wirth's examples in
962 Programming in Modula-2 ed.4.
963 valprint.c Added support for "set radix 2" by then setting
964 output_format to 't'.
965 eval.c Implemented range checking on subrange types. Added calls
966 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
967 Implemented MIN and MAX for ennumerated types. The
968 minimum value of an ennumerated type is defined by Wirth
969 as the first identifier, and the maximum as the last.
970 m2-exp.y Made octal numbers ending with "B" be characters and those
971 ending with "C" be numbers, per Wirth's book. (p. 34)
973 Thu Jun 27 14:11:52 EDT 1991
975 stack.c select_frame() now only sets working_lang, it does not
976 notify the user. If working_mode is language_manual, then
977 a warning is issued once.
978 main.c At the end of each call to execute_command(), working_lang
979 is checked against the local static (enum language)
980 current. If they differ and working_mode is
981 language_auto, the new settings of language, type and
982 range checking are printed out.
983 stack.c Modified frame_info() to include the language of the
984 current frame in the output of "info frame".
985 language.[ch] Added the function language_str() which returns the name
986 of the current language.
988 Fri Jun 28 15:33:14 EDT 1991
990 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
991 the language. INCL and DECL currently cause an error,
992 since sets are not implemented yet. INC and DEC are
993 implemented as PREINCREMENT/PREDECREMENT with one
994 argument, and as ASSIGN_MODIFY with two arguments.
995 eval.c Added type checking to the above cases.
996 value.h Added not_lval_constant to the lval_type ennumerated type.
997 not_lval_constant means that the value is a constant
998 value; that is 3 or 'a' or TRUE, not as in a constant
999 identifier. This is used to help coerce numbers such as 3
1000 to either signed or unsigned numbers.
1001 valops.c Added the function value_coerce_constants() which coerces
1002 constant integers as following: if one is a constant and
1003 the other is not, the constant's type is set to the type
1004 of the other argument. If both are constants and one is
1005 signed, the other is converted to a signed constant.
1007 Sat Jun 29 17:26:29 EDT 1991
1009 valarith.c Added a better range checker. It now checks range
1010 (successfully) on integral operations [+-] (signed and
1011 unsigned) for any C sized type. Still does not work well
1012 for multiplication.)
1013 int_in_size() returns an integer that is coerced to fit into
1014 specified number of bytes.
1016 Mon Jul 1 13:04:14 EDT 1991
1018 language.[ch] Added the function binop_result_type(), which returns the
1019 builtin (struct type *) type that would be the result of a
1020 binop on the two values V1 and V2.
1022 Wed Jul 3 19:22:53 EDT 1991
1024 source.c Extended source_info() to include the source language in
1025 the output from "info source".
1027 Fri Jul 5 13:48:52 EDT 1991
1029 utils.c Moved the support functions for the GDB set/show commands
1030 dealing with language into language.c.
1031 language.c Added the function language_info(), which displays info
1032 about the current working language, type and range check
1033 settings. Called via the GDB command "info language".
1034 Added an initialization routine _initialize_language(),
1035 that sets defaults for the language, type and range
1036 variables and sets up the new GDB commands.
1037 main.c Language setup moved to language.c.
1040 Mon Jul 8 10:10:22 EDT 1991
1042 valarith.c Debugged the range checker for arithmetic. Still does not
1043 work for multiplication very well.
1045 Mon Jul 8 12:40:37 EDT 1991
1047 language.[ch] Added the function value_true() which returns non-zero if
1048 its argument represents a boolean true value.
1049 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1050 check the truth of an expression.
1052 Thu Jul 11 12:51:34 EDT 1991
1054 language.[ch] Added the predicate structured_type(), which returns
1055 non-zero if the argument is a structured type.
1056 Added the predicate pointer_type(), which returns non-zero
1057 if the argument is a pointer type.
1058 eval.c Added the ability to do addition and substraction on
1059 pointers and integers. This case simply bypasses the
1062 Thu Jul 11 14:41:42 EDT 1991
1065 Added the symbol N_DEFD (0x4a) which is a definition
1066 module dependency that is used by the GNU Modula-2
1067 compiler and the linker. It is not important to GDB,
1068 except that [dbx|coff|mips]read.c should ignore these
1071 Fri Jul 12 16:07:00 EDT 1991
1073 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1074 0 in val_print(). Also added statements to the else part
1075 to coerce type (argument to val_print) to a pointer type
1076 if it is an "array of unspecified length".
1077 valops.c Added the function value_m2_string(), which returns a
1078 (value) value which is a constant string, whose type is
1079 (ARRAY [0..n] OF CHAR). The length field of the type
1080 structure is set to zero, so it will be interpreted as an
1081 "array of unspecified length".
1082 stack.c Moved the language/frame mismatch check to
1083 main.c:execute_command().
1084 main.c The working language is recorded each time
1085 execute_command() is executed. If working lang has
1086 changed during its execution, then the new
1087 language/type/range info is printed out for the user. If
1088 the working language does not match the language of the
1089 frame, a warning is issued.
1091 Sat Jul 13 16:16:39 EDT 1991
1093 eval.c Moved all the type-checking stuff for operators to
1094 language.[ch] language.c. This is so we can keep language-specific
1095 stuff (like for what type operators are defined) in
1097 language.[ch] Added the function binop_type_check(), which checks to see
1098 if its two (value) arguments are type-compatible with its
1099 opcode argument. The opcode should represent an operation
1100 involving an operator. Also added the macro function
1101 unop_type_check, which calls binop_type_check with a
1102 NULL second argument.
1103 expprint.c Added Modula-2 operators to the op_print_tab, so info
1104 expression.h break works correctly. Also added "op_string", which
1105 returns the string corresponding to the (enum exp_opcode)
1106 opcode that is its argument.
1109 Sat Jul 13 18:26:18 EDT 1991
1111 coffread.c Added code to record the type of function arguments with
1112 each paricular function. Code is very similar to that
1114 dbxread.c Moved add_param_to_type() to symtab.c
1115 symtab.[ch] Added function add_param_to_type() from dbxread.c
1117 *** NOTE: The above additions have not been tested.
1119 Mon Jul 15 12:50:47 EDT 1991
1121 langauge.[ch] Added the functions type_error and range_error, which work
1122 like error() except if the type/range mode is set to
1123 *_mode_warn, then they do not do a return_to_top_level(),
1124 but merely print a warning.
1125 Also changed [set|show]_[type|range]_command() to support
1126 the new "warn" feature.
1128 Thu Jul 18 17:50:54 EDT 1991
1130 mipsread.c Added code to record the type of function arguments with
1131 each particular function. Code is very similar to that
1134 *** NOTE: The above additions have not been tested.
1136 Fri Jul 19 11:19:10 EDT 1991
1138 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1139 UMIN_OF_SIZE, which when given a size of a numeric type,
1140 return the maximum and minimum value it can hold. UMAX...
1141 and UMIN... return the result for unsigned types.
1142 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1143 struct types. They call above macros.
1144 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1145 avoid a name conlict with the above.
1146 c-exp.y Added range checking on numeric constants in
1147 parse_number() for completeness.
1148 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1149 return 0 if working_lang is not language_c.
1151 Thu Aug 8 14:17:22 EDT 1991
1155 breakpoint.c Documentation strings of some commands changed to
1156 eliminate the references to the C language where
1159 Tue Aug 13 15:48:03 EDT 1991
1161 m2-exp.y Added qualified identifiers to the grammar. The semantics
1162 are slightly different from those of the GDB operator ::
1164 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1165 type_exp, where type_exp is any valid type expression.
1167 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1168 printcmd.c Modified ptype_command() so it actually parses the input
1169 (necessary for type expressions with scope qualifiers).
1170 Added the function ptype_eval() which expects an
1171 expression composed of one OP_TYPE element.
1172 *.[ch] Replaced all occurences of parse_c_expression with
1174 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1176 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1178 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1180 Small fixes from Peter Schauer:
1182 * infrun.c (child_attach): Lint.
1183 * solib.c (find_solib): Handle shared libs version 2.
1185 Small fixes from David Wood:
1187 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1191 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1192 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1194 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1195 chars_per_line is at maximum (user typed `set width 0'). Fix
1196 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1198 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1200 * coredep.c: include ptrace.h where necessary.
1201 * mipsread.c(parse_lines): fix unsigned char problem that was
1202 messing up line numbers on SGI's and possibly other MIPS based
1204 * infrun.c (child_create_inferior): use better test to check
1205 return val from setpgrp().
1206 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1207 for sgi/irix support.
1209 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1211 * mipsread.c (parse_symbol): Put non-static procedures
1212 in the global block.
1214 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1216 Patch together `text_start' and `text_end' for 29K port.
1218 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1219 variables and set them based on the exec file.
1220 * am29k-tdep.c: declare text_start.
1221 * valops.c (call_function_by_hand): declare text_end.
1223 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1224 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1225 because machines that do this will also have to know to
1226 set NEED_TEXT_START_END. Besides, it was a redundant way to
1228 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1229 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1230 NEED_TEXT_START_END.
1232 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1234 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1236 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1237 Pass MUNCH_DEFINE to munch whenever we run it.
1238 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1239 format string; use 0x%x instead.
1240 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1241 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1242 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1243 * inflow.c: Handle `short' process group IDs.
1244 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1245 and check for ptrace errors.
1246 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1247 (coff_symfile_init): Initialize text_bfd_scnum.
1248 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1249 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1250 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1251 Merge target arm case with other "easy" cases. Add target
1252 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1253 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1255 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1256 * munch: Cope with RT/PC putting fns in data segment.
1257 Restore ability to override `nm' by specifying MUNCH_NM.
1258 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1259 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1260 and remote-adapt. Remove encapsulated coff #define's (the
1261 support should go in BFD, and gdb shouldn't know or care).
1262 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1263 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1264 * tm-29k.h: Update BADMAG (though it should go away).
1265 Allow the register definitions to be overridden in another
1266 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1267 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1268 DUMMY_SAVE_GR96, for handling kernel calling conventions
1269 that use GR64+ rather than GR96+.
1270 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1271 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1272 overrides various things.
1274 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1275 child_attach does, making a clean stop in the newly attached
1277 * remote-eb.c: Lint.
1279 * coffread.c: Make coffread independent of any particular
1280 variant of COFF. Avoid #include-ing any particular one except
1281 internalcoff.h. BFD now passes key values for symbol reading
1282 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1283 and the symbol masks and shifts); use them.
1284 Remove obsolete end_of_text_addr.
1286 * exec.c: Remove unused include files.
1288 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1290 * Makefile.in (documentation targets): Pass $(M4).
1291 Bugfix from eggert@twinsun.com (Paul Eggert).
1293 * stack.c (down_silently_command): Check for stack existence.
1295 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1297 * Makefile.in (VERSION): Update to 4.0.3.
1299 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1301 * core.c (core_file_command): Print frame at coredump with
1302 its level number, by calling print_stack_frame.
1303 * frame.h: Add selected_frame_level, print_stack_frame.
1304 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1305 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1306 Change print_sel_frame and print_selected_frame callers to
1309 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1310 * symfile.c (free_named_symtabs): Ditto.
1311 * main.c (main): wrap_here needs an arg.
1312 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1313 (solib_add): Avoid noise.
1314 (solib_create_inferior_hook): Lint.
1315 (sharedlibrary_command): Move dont_repeat to here.
1316 * utils.c (error): Call wrap_here to force buffered output.
1318 Small patches from Peter Schauer:
1320 * coffread.c (start_symtab): Free any existing line_vector before
1322 (read_coff_symtab): Ditto for type_vector.
1324 * source.c (lines_to_list): New variable, replacing function.
1325 (all uses): Use as variable.
1326 (_initialize_source): Add 'set listsize' and 'show listsize'.
1327 * utils.c (lines_to_list): Remove function.
1328 * stack.c (print_frame_info): Use as variable.
1329 * defs.h (lines_to_list): Remove declaration.
1331 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1333 * breakpoint.c (insert_breakpoints): Restore warning about
1334 the program might be running in another process, but only for
1335 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1336 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1338 * utils.c (error): if error_pre_print is set, print the string
1340 * main.c (main, print_gnu_advertisement, print_gdb_version):
1341 Reformat legalese so it always prints, but acts as an "I'm here"
1342 message while symbols are being read. If any errors occur,
1343 print a few newlines to set off the message and start it at the
1344 left margin. Remove mention of "help" command, and don't yak
1345 about symbol reading.
1346 (catch_errors): Error string is now printed first in case of
1348 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1349 suggest the "help" command.
1351 * Makefile.in (VERSION): Set to 4.0.2.
1353 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1355 * .gdbinit: Remove useless "rr" command. Set complaints
1356 to 1 for people debugging gdb.
1358 * breakpoint.c, remote-vx.c: Reword strings printed by
1359 catch_errors callers.
1361 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1363 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1364 (Fix from kenc@viewlogic.com.)
1366 Fix some infrastructure to be able to cope with host and target
1367 machines with different sized basic types (ints, ptrs, etc).
1368 (Idea from pierre@la.tce.com (Pierre Willard).)
1370 * values.c (value_from_longest): Rename from value_from_long.
1371 Handle pointer types as well as integers, so that targets with
1372 different pointer sizes from the host can be accomodated.
1373 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1374 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1375 uses of value_from_long to value_from_longest.
1376 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1377 the correct pointer type to value_from_long{est}.
1379 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1381 * remote-vx.c: Remove obsolete code for calling functions via
1382 vxworks kludge interface (it referenced value_from_long).
1384 * valops.c (value_string): Find malloc with lookup_misc_func, not
1387 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1389 Make writing to files work properly. (Fixes to BFD are also needed.)
1391 * core.c (core_open): Open file ourselves, read or r/w, depending on
1392 write_files. Use bfd_fdopenr.
1393 * gdbcore.h (write_files): New variable.
1394 * exec.c (write_files): Define variable, add set&show for it.
1395 (exec_file_command): Use write_files to open for read or r/write.
1397 Make shared library reading happen automatically. These changes
1398 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1400 * inferior.h (stop_soon_quietly): Add to exported variables.
1401 * infrun.c (child_create_inferior): call solib hook, if defined.
1402 (child_attach): call solib hook, if defined.
1403 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1404 (find_solib): Use lookup_misc_func rather than hand-rolled.
1405 (symbol_add_stub): New stub for catch_errors.
1406 (solib_add): Avoid output if !from_tty. Catch errors rather
1407 than just calling symbol_file_add and bombing.
1408 (solib_create_inferior_hook): Interface with the target process
1409 to let it read and alloc shared libs, then figure out what it did.
1411 * core.c (validate_files): Fix typo, soften warning.
1412 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1414 * utils.c (fputs_demangled): Avoid duplicate printing if
1415 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1417 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1418 (Fix from pierre@la.tce.com (Pierre Willard).)
1420 * main.c (catch_errors): Change argument to a char * from an int,
1421 since a char * can point to a struct full of glop, but an int
1422 is not guaranteed to be able to hold a pointer.
1423 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1424 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1425 * core.c (core_open, solib_add_stub): Adapt.
1426 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1428 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1430 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1431 by adding .NOEXPORT target.
1433 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1437 * Makefile.in (VERSION): Roll to 4.0.
1438 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1440 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1442 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1445 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1448 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1450 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1451 reflect above name change
1453 * WHATS.NEW: correct pointer to refcard.
1455 * doc/gdb.texinfo: update New Features, Installing
1457 * doc/gdbint.texinfo: add short description of configure +template
1459 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1461 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1463 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1465 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1466 tar file, add dependencies for referenced doc files.
1468 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1470 * coffread.c, symfile.c, stack.c: saberized.
1472 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1474 * doc/refcard.tex: permuted Essential Commands sec
1476 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1478 set/show symbol-reloading
1479 default set complaints 0
1481 RET-repeat disabled after prompted long displays
1482 processID (attach) interpretation of 2nd GDB cmdline arg
1484 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1486 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1487 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1488 breakpoint.c, main.c: lint.
1490 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1492 Install new configuration scheme for GDB and friends.
1494 * config.sub: Translate ordinary names to three-part names.
1495 * configure: Use three-part names internally.
1496 * configure.in: Translate three-part names to filenames.
1498 * README, WHATS.NEW: Update for gdb-4.0.
1499 * Makefile.in: Roll VERSION to 3.99.
1501 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1503 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1504 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1505 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1506 to single structures rather than arrays; when passing
1507 their address, use &. This avoids trouble with bdead compilers.
1508 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1509 instead. This avoids portability headaches.
1510 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1512 * source.c (open_source_file): Avoid ANSI const bdeath by
1513 skipping declaration and then casting result value.
1514 * tm-hp300bsd.h: Clarify comment.
1515 * utils.c (strstr): Result is const char *; ANSI bdeath.
1516 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1517 since system include file defines it differently from "defs.h",
1518 though the two are equivalent for our purposes.
1519 * tconfig/hp300bsd: Add m68k-tdep.o.
1521 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1523 * tconfig/sun*4: Remove warnings about system assembler.
1525 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1527 * mcheck.c: Avoid warning about undeclared abort fn.
1528 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1529 it causes recursive calls to error() when used in cleanups.
1530 To do so requires that we make it a function, so we do.
1531 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1532 * utils.c (do_cleanups): Remove the current cleanup from the
1533 chain *before* calling it, in case error() is called from it.
1534 The result won't be pretty, but won't be an infinite loop either.
1536 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1538 * dbxread.c (read_struct_type): Grok anon structs for C++.
1539 (vb_name, vptr_name): Null terminate these strings.
1541 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1543 Minor bug fixes from BSD Net2 gdb:
1545 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1546 returns 0, there is no previous frame.
1547 * breakpoint.c (commands_command): If !from_tty, don't call
1548 input_from_terminal_p().
1549 * dbxread.c (record_misc_function): Speed up slightly.
1550 (compare_psymbols): Ditto.
1551 * infcmd.c (do_registers_info): Take a second argument to
1552 determine whether to print float registers. "info registers"
1553 does not do so anymore. "info all-registers" does, now.
1554 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1556 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1557 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1561 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1562 executing_breakpoint_commands if we are interrupted by error.
1563 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1564 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1565 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1566 catch_errors() so we can setup the frame regardless of whether
1567 the shared libs work.
1568 * ieee-float.c (double_to_ieee_extended): Get exponent from
1569 right place in little-endian systems. From John Carey.
1571 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1573 * main.c: Remove unused terminating_signals and catch_termination().
1574 (long_options): Terminate with a zero element.
1575 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1576 (gdb_readline): Make call-compatible with readline.
1577 (init_signals): Improve comments re vfork vs. signal.
1579 * utils.c (prompt_for_continue): Use new gdb_readline().
1580 If we prompt for continuation, we don't let CR repeat the previous
1581 command, once we get back to a prompt. It's too easy to keep
1582 hitting CR, expecting "--more--" prompts, and have some long
1583 command start repeating on you.
1585 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1587 * blockframe.c (frameless_look_for_prologue): Speed up by
1588 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1589 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1590 Define two variants, one faster.
1591 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1592 and return zero, rather than giving an error.
1593 (setup_arbitrary_frame): Initialize the PC in the new frame.
1594 (skip_prologue): Add a second arg saying whether we're just
1595 checking for a frameless function or not.
1597 * core.c (core_open, core_close, core_xfer_memory): Move
1598 section table pointers and bfd* into the target_ops.
1599 (core_open): Allow errors in shared lib reading, etc.
1600 (core_files_info): Describe shared library sections.
1602 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1603 exec_files_info, set_section_command): Move section table
1604 pointers and bfd* into the target_ops.
1605 (add_to_section_table): Add BFD to section table.
1607 * target.c (target_xfer_memory, target_info): Pass target to
1608 xfer_memory and target_info functions.
1611 * gdbcore.h: Move struct section_table.
1612 * target.h: New home of struct section_table.
1614 * solib.c (solib_add): New argument is the target_ops whose
1615 section list is to be added to, if any. Reallocate the
1616 sections in that target to add any that come from shared libs.
1617 (throughout) so_sections renamed to sections.
1618 (solib_xfer_memory): Deleted.
1619 * tm-sunos.h (SOLIB_ADD): Add target argument.
1620 (SOLIB_XFER_MEMORY): Delete.
1622 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1623 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1624 from target_ops. It's the same on all targets. Add two section
1625 pointers to target_ops.
1627 * stack.c (find_relative_frame): Dump ancient algorithm for
1628 "down", just use handy "next" pointers.
1629 (frame_command): Don't error if there is no stack; let user
1632 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1633 modifies static state in the parent process; new_tty itself
1634 runs in the child and modifies the child's file descriptors
1635 to match the saved static state.
1636 * infrun.c (child_create_inferior): Call new_tty_prefork,
1639 * infptrace.c (child_xfer_memory): Add ignored target arg.
1640 * remote-eb.c (eb_xfer_inferior_memory): ''
1641 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1642 * remote-vx.c (vx_xfer_memory): ''
1643 * remote.c (remote_xfer_memory): ''. Rename from
1644 remote_xfer_inferior_memory.
1646 * main.c (main): Only try to attach "corefile" argument if
1647 it starts with a digit.
1649 * symfile.c (symbol_reloading): New "set/show" variable.
1650 (symbol_file_add): Shorten message about symbol reading.
1651 (add_symbol_file_command): Merge with add_syms_addr_command,
1652 since this should work on all targets now.
1653 (stop_whining): Default to zero, to shut up complaints
1654 about bad symbol tables on many systems.
1655 (free_named_symtabs): Just exit unless symbol_reloading.
1657 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1658 and add comment explaining shared library screw.
1660 * source.c: #if defined => #ifdef.
1662 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1664 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1666 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1668 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1669 (doc/Makefile knows how to make one for local config)
1671 * Makefile.in: use doc/Makefile for doc targets
1673 * doc/Makefile: GDB documentation now has its own Makefile
1674 doc/refcard.tex: renamed from "gdbrc.tex"
1675 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1676 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1679 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1681 * values.c (baseclass_addr): When reading target memory, use the
1682 length of the basetype, not the upper type. We've only malloc'd
1683 enough space for the basetype, leading to errors in free().
1685 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1686 ends up as a function specially, since we know the actual type of
1687 the pointed-to address. This (somewhat) fixes display of
1688 expressions that include misc_function_vector names. Try `cond 1
1689 !strcmp("a","b")' then `i b'.
1691 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1692 The child can be proceeded from inside wait_for_inferior in
1693 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1694 getting skipped in that case.
1696 * expprint.c (print_subexp): Use filtered output, since the
1697 subroutines we call use it, otherwise the output is horribly
1698 mangled, since output of wrappable stuff comes out late.
1700 * Makefile.in: Bump VERSION to 3.98.1
1702 * infrun.c (child_create_process): Use execlp to find the
1703 shell to exec our target program. This requires some fiddling
1704 with `environ' since there is no execlpe().
1706 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1708 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1709 Minor rearrangement of refcard permits two new make targets--
1710 gdbrc.dvi DVI output for refcard, using CM fonts
1711 gdbrc.ps PostScript refcard, using PS fonts
1713 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1717 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1718 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1720 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1722 * doc/gdb.texinfo: last changes for release.
1723 Minor typo and formatting fixes; incorporated most fixes remaining from
1724 filed mail commenting on earlier drafts.
1726 Added warnings: pipes don't work in run command;
1727 conditions are converse of assertions;
1728 step over fn without debug info goes to next fn;
1729 vars may have "wrong" values near fn entrance, exit
1731 Added example from Kingston on printing repeated nonadjacent values
1733 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1734 shell mode for signals
1736 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1737 doesn't sound so much like its parent "Stopping and Continuing"; also
1738 moved entries on continue to top of section, so they don't get lost.
1740 Improved installation directions in appendix, added manual formatting
1743 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1745 * configure.in: Remove xm.h and tm.h even if we aren't linking
1746 new ones, so "./configure sun4; ./configure none" does the right
1747 thing. Assume that alldeps.mak and depend are already built in
1748 srcdir, and avoid running "make" (particularly "make depend",
1749 which involves "gcc") from inside configure. Build Makefile
1750 directly rather than building Makefile.conf first.
1751 * configure: Regenerate with above changes.
1752 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1753 to 3.98. Revise gdb.tar.Z procedure to produce a file
1754 called gdb-$(VERSION).tar.Z but which unpacks into a
1755 directory called "gdb". Move non-source files out of
1756 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1757 (depend): Don't try to do "gcc expread.y".
1758 (expread.o): Update dependencies by hand.
1760 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1763 Fixed a variety of small typos that prevented info from formatting
1764 cleanly; altered too-long heading for GPL Appendix, as discussed
1765 w/RMS; Changed date on cover to July 91.
1767 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1770 (1) Applied some fixes due to comments from Larry Breed (easier ones
1771 through chapsec 5.2)
1772 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1773 it's broken in latest texinfo
1774 (3) Introduced *some* use of [] for optional arguments, where
1775 explanation is not simpler by listing cmd w arg and cmd w/out arg
1776 separately. Still not using @deffn.
1777 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1778 couple of headings are too long. Need patches to texinfo or revision
1781 * Partial update to README (which still needs work for this
1782 release!): (1) use of configure corrected for new script,
1783 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1785 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1787 * symtab.c (lookup_symbol): Don't complain right off about
1788 no debug symbols; use the misc function vector first.
1789 (list_symbols): Use misc function vector to find symbols
1790 that don't have debug info, and print them.
1791 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1792 PC range doesn't match symtab PC range, as it does on the
1793 MIPS because our symtab reading isn't perfect.
1795 * dbxread.c (dbx_symfile_read): Make warning about
1796 "no debug symbols" slightly nicer.
1798 * source.c (select_source_symtab): If "main" symbol exists,
1799 but decode_line_spec can't find line info, don't just return
1800 a zero; try other source symtabs or give an error.
1802 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1803 their low addresses first, then rip through fixing high addrs.
1805 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1806 <runene@ifi.uio.no>.
1807 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1809 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1811 * Minor, mostly mechanical, cleanup of doc subdir for clean
1812 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1813 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1815 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
1817 Mostly MIPS and general symbol-reading fixups.
1819 * doc/gdbint.texinfo: Add documentation on symbol-reading
1822 * mipsread.c: Remove kludges around #include "ecoff.h".
1823 Remove redefinitions of a_magic, etc, no longer used.
1824 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
1825 Fix global overview comments to match symfile.c protocol.
1826 (mipscoff_new_init): Eliminate cur_hdr if we have one.
1827 (mipscoff_symfile_read): Eliminate unused code. Avoid
1828 sorting all the symtabs, when all we have read here is psymtabs.
1829 The symtabs are sorted as they are created anyway. Tell
1830 condense_misc_bunches whether we're mainline.
1831 (psymtab_to_symtab_1): Pass filename when recursing, to make
1832 stack trace more informative.
1833 (parse_partial_symbols): Assume cur_hdr as argument.
1834 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
1835 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
1836 the TYPE_NAME of char *, since that's done in symfile.c.
1837 (free_numargs, parse_symbol, add_symbol, add_block,
1838 shrink_linetable): Declare these fns void.
1839 (upgrade_type): Convert tree of if's to switch. Clean up
1840 bogus "off == 0" handling with a complaint. Avoid setting
1841 field bitpos and bitsize of array with lower and upper bounds.
1842 Check specified bitsize of elements against their actual type's
1843 bitsize, and complain if different. Complain about unknown
1845 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
1846 (psymtab_to_symtab_1): Print names of subsidiary files that
1847 are being read in. FIXME, we read far too many files. This code
1848 is not the problem, the problem is in parse_fdr where the psymtabs
1850 (cross_ref): Result should indicate that we used one aux entry
1851 normally, or two if we encountered a "next" entry. This used
1852 to leave the caller pointing at the wrong aux entry.
1853 (add_symbol): If overflowed cur_block, reallocate it larger,
1854 chase all pointers to it, and complain(), rather than clobber memory.
1855 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
1856 (new_field): Only allocate one field initially, not two.
1857 Pull ++ out of macro argument. Simplify.
1858 (_initialize_mipsread): Avoid initialization of importd
1859 global_psymbols and static_psymbols.
1861 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
1862 to properly set pst->symtab; avoid searching for it.
1863 (symfile_fns): Improve comments, add a FIXME.
1864 * dbxread.c: Update comments to reflect symfile protocol.
1865 (read_ofile_symtab, end_symtab): Return the symtab.
1866 (psymtab_to_symtab_1): Set pst->symtab.
1868 * coffread.c (coff_symfile_read): tell condense_misc_bunches
1869 whether we're mainline.
1871 * symfile.h (sym_fns): Remove unused sym_discard member.
1872 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
1874 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
1875 the environment variable is not.
1876 * infcmd.c (finish_command): Use filtered printfs.
1877 * cplus-dem.c: Add struct tags to a few unnamed structs.
1878 * valops.c (value_coerce_array): Improve comments.
1879 * valprint.c (type_print_varspec_suffix): Print array size only
1880 if greater than zero.
1881 * m88k-tdep.c: Shift some lines left by one space, that had
1882 apparently been trashed at some point.
1883 * TODO: More things to do, a few got done.
1885 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1887 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
1888 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
1890 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
1891 * expread.y, findvar.c, symmisc.c: Ditto.
1892 * printcmd.c (address_info): Update printed forms of LOC_
1893 symbols. Elim LOC_EXTERNAL.
1894 (print_frame_args): Keep track of param stack offsets before
1895 re-looking up to find the local register param is kept in.
1897 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
1898 Further integration of mipsread into gdb. Eliminate unused
1899 routines, duplicate declarations. Handle static symbols in
1900 psymtabs as well as external symbols. When reading symtabs,
1901 insert symbols into the correct block (global, static, or a local
1903 (read_mips_symtab, parse_partial_symbols): Don't pass useless
1905 (mipscoff_symfile_read): Don't call select_source_symtab.
1906 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
1907 rather than SYMBOL_VALUE.
1908 (parse_external): Comment clobbering of top_stack.
1909 (parse_partial_symbols): Update comments. Allocate and parse
1910 static symbols as well as external symbols. FIXME, enum values
1911 are not handled in this pass, but should be. Inline new_psymbol.
1912 Use SYMBOL_VALUE_ADDRESS.
1913 (psymtab_to_symtab_1): Read symbols into global static block
1914 by default (until enter some function's local block context).
1915 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
1916 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
1918 * source.c (select_source_symtab): Select a source symtab
1919 from either the symtabs or, failing that, the psymtabs.
1920 (list_command): Update error message.
1921 (forward_search_command, reverse_search_command): Use getc, not
1922 fgetc, for speed. FIXME, add comment about buffers that die if
1923 overrun by long line.
1925 * values.c (unpack_field_as_long, modify_field): Avoid shifting
1926 by an entire word, which is not portable, if we have a 32-bit
1927 field. (Code in dbxread.c already turns such bitfields, if
1928 aligned, into ordinary ints, but fixing this will help for other
1929 symbol formats and for future changes.)
1930 * core.c (core_open): Handle ANSI const brain death.
1931 * utils.c (vprintf): Fix varargs typo.
1933 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1935 * findvar.c (find_var_value): Handle &function better.
1936 * TODO: Document work needed on &fn and &array.
1937 * printcmd.c (print_address_symbolic): New arg is the prefix
1938 to print if a name is printed.
1939 (print_address_demangle): Honor "set print address" now.
1940 Use new arg above to improve spacing of output.
1941 * valprint.c (val_print): When printing function pointers,
1942 print symbolic form too.
1943 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
1945 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1947 * core.c (memory_error): Reword error msg to mislead less.
1949 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
1951 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
1952 parse_partial_symbols): Use newer BFD internals (external_filehdr
1953 and external_aouthdr), byte-swap the fields that we care about
1954 before using them, and make the file header data local to
1955 read_the_mips_symtab rather than global.
1957 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
1959 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
1960 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
1962 * main.c (command_line_input): Flush stdout and stderr
1963 before every call to readline. This reportedly fixes a bug
1964 that comes up in Sys V running emacs-gdb and/or xxgdb,
1965 when stdin/out are pipes or sockets.
1967 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1969 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
1970 Avoid declaring Makefile dependencies, because GNU Make stupidly
1971 tries to update it if we do.
1973 * coffread.c: Revise for minor changes to bfd internal coff
1976 * configure: If -template= is given a relative path, make it
1977 absolute before recurring in subdirectories.
1979 * configure, configure.in, Makefile.in: Install "configure" script
1980 as replacement for config.gdb.
1981 * config.gdb, Makefile.dist, Makefile.sdir: Remove
1982 * README: Update for configure, mostly. FIXME.
1984 * Add dec3100 as equivalent to littlemips. Indicate in all host &
1985 target config files that they are for the host. When the lines
1986 get copied into the Makefile, this makes it more obvious what's
1989 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1991 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
1992 tabs, which end up in the disassembler output inadvertently.
1994 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1996 Make it compile cleanly in an ANSI GCC2 environment.
1998 * blockframe.c: <stdio.h>
1999 * cplus-dem.c: free takes a void *, ifdef __STDC__
2000 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
2002 * defs.h (alloca): Avoid doing anything if alloca already def'd.
2003 * stddef.h, stdlib.h: Remove these files.
2004 * symtab.c: Avoid declaring qsort, close.
2005 * symfile.c: Avoid declaring close.
2006 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
2007 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
2009 Assorted other changes.
2010 * dbxread.c: include "libaout.h", not "liba.out.h".
2011 * printcmd.c (print_frame_args): Set recurse properly for
2012 indentation of struct and array parameters.
2013 * valops.c (value_cast): Allow cast to void.
2014 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2015 single_step() in a target-independent fashion.
2016 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2017 set up to be ready to continue. This makes us target independent.
2018 * infptrace.c (child_resume): Remove call to single_step; now
2019 can single step a SPARC target of any kind.
2021 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2023 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2024 docn into separate sections---basically chapters, plus two loose
2025 pieces that can be configured to go in different places. This
2026 allows GNU m4 to preprocess the manual without coredumping.
2028 * Makefile.dist: tell TeX where to find texinfo.
2030 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2032 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2033 the new target "rdl-apps.texinfo" which captures the Makefile
2034 variable that records where to find the Readline libraries.
2036 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2038 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".

2041 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2043 * README: Update for release 3.95.
2044 * config.gdb: Don't create readline dir in subdir builds.
2045 * main.c: Include with "..." form for non-system include files,
2046 so "gcc -MM" for "make depend" works.
2047 Include readline files with "...h" rather than <readline/...h>.
2048 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2050 * coffread.c: Undo minor damage done by Rich Pixley. Use
2051 different internal and external representations of COFF
2052 data structures. Use new BFD routines for swapping them in and
2054 * symfile.c (free_named_symtabs): Avoid freeing file names that
2055 are null or empty. Old i960 tools seem to produce files that
2056 claim to have empty names, causing each successive file read
2057 to blow away the previous one.
2058 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2059 Move deferred_stores to top of file, but don't separate its
2060 #define's from its variable. Add commentary.
2061 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2062 favor of keeping the (working) config.gdb. Move readline
2065 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2067 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2069 * infptrace.c (fetch_registers): no result, since now void.
2070 * tconfig/news: target depends on m68k-tdep too.

2074 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2077 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2078 applied various small fixes due to or inspired by RMS comments
2080 * doc/gdb.texinfo: finished using all RMS comments, save those for
2081 appendices on readline and cmd history (which are in other source
2084 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2086 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2087 chapter 9; (2) documented 'break' command's menu mode for
2088 overloaded names, in response to hgs problem report C++ p-31
2090 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2092 * doc/gdb.texinfo: (1) better introductory example; (2) more
2093 consistent use of @code, @samp, @file, @kbd throughout; small
2094 cleanups to first three nodes; (3) new "Contributors" node;
2095 (4) Appendix, Renamed Commands; (5) divert specialized startup
2096 instructions to "Targets" chapter for generic manuals, while
2097 leaving them up front for manuals specific to specialized
2098 environments; (6) apply fixes from RMS comments through chapter 4.
2100 * pretex.m4: modify explanatory text slightly (and redefine
2101 "regexp") to keep GNU m4 from complaining. (It still crashes
2102 later, but one step at a time...)
2104 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2106 * readline/readline.c (update_line): Avoid dereferencing a pointer
2107 before comparing it to its bounds. Saber caught this.
2108 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2109 and only set PC if tgetstr returned non-null. Saber caught this.
2111 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2113 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2114 stuff for config manual) here where it counts; updated
2115 to use new subdir structure (gdb/doc/).
2117 * Makefile: generated from above via
2121 * gdbint.texinfo: added instructions on generating gdb.info* files
2122 locally for release. These are ordinary info
2123 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2124 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2125 to generate these, so we distribute them already formatted.
2127 * gdb.texinfo: included full Info node and menu crud (as generated
2128 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2130 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2131 put in comments-for-future gdb.info target (one day makeinfo will
2134 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2136 * gdb.texinfo: Updated to include new or old undocumented
2137 commands, at least the following (perhaps some others I forgot to
2138 record): info f, info float, info path, info program, info s, info
2139 set, info source, info terminal, info types, info user, set/show
2141 Also covered all recent GDB command renames for v4.
2143 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2145 * mipsread.c: Rather than keeping count of how many symtabs
2146 and psymtabs we have, for sorting purposes, count them when
2147 we need to sort. This fixes bug in rereading of symbol tables.
2149 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2151 * infcmd.c: renamed "info path" to "show paths"

2166 symtab.h, target.c, target.h: Lint.
2167 * core.c: setup and select frame after reading shared libs,
2168 else reading shared libs will clobber them. Lint.
2169 * utils.c (error): Force out any buffered wrap text.
2171 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2173 * remote.c: Remove decls of memory_insert_breakpoint
2174 and memory_remove_breakpoint, no longer used. (Suggestion of
2177 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2178 to make it easier to interface to "configure"'d libraries.
2180 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2182 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
2183 aliases for set/show print.

2732 been read in, particularly for VxWorks.
2734 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
2735 to the main file, as well as to include files. Also, put global
2736 functions into the global psymtab, to make "i fun" work.
2737 (end_psymtab): Free named symtabs and psymtabs for a file, once a
2738 new psymtab for it has been read.
2739 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
2740 a file, once a new symtab has been read for it.
2741 * mipsread.c: FIXME. We need to do the same for MIPS, but it
2742 looks harder to determine the top-level block before it's been
2743 queued to the psymtab list.
2745 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
2746 If we have wiped out any old symbol tables, clean up at end of
2748 (symbol_file_command): Don't reference symfile_fns if it's zero.
2750 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
2751 defines for the blocks of a blockvector that contain global and
2752 file-static symbols and the first of the smaller scope contours.
2753 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
2754 decode_line_1, make_symbol_completion_list): Use the above.
2755 * coffread.c (end_symtab, patch_opaque_types): Ditto.

2761 * symtab.c (list_symbols): Process the first symbol of the
2762 static psymbols list.
2763 (types_info): Restore this function from its untimely #if 0.
2764 It's not perfect, but it is better than nothing.
2765 (_initialize_symtab): Restore "info types".

2769 * m68k-stub.c: Remote stub for 680x0's, created from

2776 * symmisc.c (free_named_symtab): Make it work, in its current

2780 * symfile.h: free_named_symtab now returns an int.
2782 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
2784 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
2785 is the first symbol read, even if not mainline.
2786 (dbx_psymtab_to_symtab): symfile might be zero, cope.
2787 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
2788 (set_section_command): New command ("section xxx yyy" -- should
2789 be renamed to "set section xxx yyy" FIXME) which sets the
2790 base address of a section of the exec file, overriding the
2791 virtual address that BFD reports.
2793 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2795 * exec.c: Add add_syms_addr_command to exec_ops, so you can
2796 load symbols at any address while examining an exec file.
2798 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2800 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
2801 for printing the float info is host-dependent, not
2802 target-dependent. FIXME.
2803 * i386-pinsn.c: Move #includes to top, remove useless ones.
2804 * i386-tdep.c: Don't bother including <.../reg.h> since we
2805 don't use it (and it doesn't exist on host systems).
2807 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
2808 Convert negative numbers properly.
2809 (ieee_test): Make numbers really random; fix format arg.
2811 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
2812 * core.c (core_detach): Unpush core_ops, which might not be on
2813 top. We used to just pop the top, which broke things. Don't
2814 need dont_repeat() any more.
2815 (core_file_command): Psst! Don't repeat it.
2816 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
2817 * expprint.c (print_subexp): Avoid switch fallthru on
2818 BINOP_ASSIGN_MODIFY, so we can print += and such.
2819 * frame.h: Fix typo.
2820 * inflow.c (kill_command): After killing inferior, print our
2821 current frame in the core file, if we have one.
2822 (generic_mourn_inferior): When inferior dies, either select
2823 the current frame (in the new target, e.g. core file), or
2824 set both the current and selected frames to NULL.
2826 Changes from Peter Schauer.
2828 * infptrace.c: Avoid <sys/ptrace.h> on USG.
2830 * Make all file names fit in 14 characters (sigh and damn!):
2831 mv hp300hpux-xdep.c hp300ux-xdep.c
2832 mv symmetry-xdep.c symm-xdep.c
2833 mv symmetry-tdep.c symm-tdep.c
2834 mv convex-opcode.h convx-opcode.h
2835 mv tm-vxworks960.h tm-vx960.h
2836 mv tm-vxworks68.h tm-vx68.h
2837 mv Makefile.srcdir Makefile.sdir
2838 mv gdb-int.texinfo gdbint.texinfo
2839 mv remote-sa.m68k.shar rem-m68k.shar
2840 mv remote-multi.shar rem-multi.shar
2841 * Makefile.dist, README, config.gdb, convex-pinsn.c,
2842 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
2843 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
2846 * command.c (user_info_1, user_info): New command for listing
2847 the user-defined commands.
2849 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2851 * dbxread.c (really_free_pendings): Clear file_symbols
2852 and global_symbols after freeing them; otherwise, running
2853 this function twice (if it appears twice on the cleanup
2854 chain), we try to free things twice.
2856 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
2857 based on text_addr (the address of text in core), not on addr (the
2858 offset between text in the .o file and in core). This change
2859 is from Peter Schauer.
2861 * main.c: Define ALL_CLEANUPS as a cast of zero.
2862 (return_to_top_level): Use it.
2863 (main): Do all cleanups after each command run as part
2864 of the gdb startup sequence. Also do all cleanups before
2865 entering the command loop, and every time we exit the command
2866 loop and reenter. Before, the cleanups from the startup sequence
2867 were being left undone until the first error!
2868 (command_loop): Rename do_nothing cleanup to command_loop_marker
2869 so we can see it easily when examining the cleanup chain.
2870 (init_signals): Add another do_nothing for signal handling.
2871 (quit_command): Only try to kill target if it has execution.
2872 Problems in the target stack got us into a state where
2873 inferior_pid was nonzero but none of the targets had execution.
2874 In this state you couldn't exit gdb.
2876 * dbxread.c: Two changes from Peter Schauer.
2877 (echo_command): Fflush output after an echo command.
2878 (show_history): Pass all args to cmd_show_list.
2880 * utils.c (init_malloc): Call mtrace to turn on tracing
2881 if the environment variable MALLOC_TRACE is set to a file name.
2882 * mtrace.c: Add source file which provides a log of every malloc,
2883 free, and realloc to a trace file.
2884 * mtrace.awk: Add source file which analyzes the trace file.
2885 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
2886 (VERSION): Roll to 3.94.3.
2888 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
2889 (check_duplicates): Don't bother with watchpoints.
2890 (set_raw_breakpoint): Comment about danger of this routine.
2891 (watch_command): Parse and eval all args before calling
2894 * solib.c (find_solib): Avoid error in referencing memory to
2895 see if any more shared libraries have been added. This is
2896 particularly useful if the target has terminated. Bug reported
2899 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
2900 in bringing up 3.94.2 on the Sun-3.
2902 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
2903 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
2904 expression (in scope) before reenabling watchpoint.
2905 * signame.c (init_sigs): Add missing declaration of i, fix
2906 sys_siglist declaration.
2907 * source.c (list_command): Fixed range computation to use
2909 * stack.c (backtrace_command): Do not allow command if target has
2910 no stack, print informative error message.
2911 * target.c (target_command): Do not write into command line
2912 because this fails if the target command is used in a user defined
2913 command. [This change was enhanced by gnu to support any-
2914 unique-prefix matching on target names.]
2915 * valops.c (value_struct_elt): Avoid infinite loop on an
2916 erroneous attempt to print the member of function (try p main.p).
2918 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2920 * expread.y (name_no_typename): Avoid reduce/reduce errors
2921 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
2922 Since the GDB parser really doesn't use name_no_typename in a
2923 name-only context, the parser can't tell the diff between
2924 names and numbers here. Avoid allowing a name_no_typename
2925 to be a NAME_OR_*INT to resolve the conflict.
2927 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2929 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
2931 * valprint.c (val_print_fields): bitfield printing didn't handle
2932 byte order. Indirect through a few more fns to cope.
2934 * values.c (modify_field): also cope with byte order.
2936 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2938 Cleanup for release 3.94.2:
2940 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
2941 include files. Roll version to 3.94.2.
2943 * coffread.c (init_stringtab): Read length into unsigned char
2944 array before swapping; don't assume 32-bit longs.
2946 * target.c (target_info): Don't bother with get_sym_file, just use
2947 the symfile global variable.
2948 * symtab.h, symfile.c (get_sym_file): Delete it.
2950 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
2951 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
2952 (read_type): Replace one more error() with complain().
2954 * mipsread.c (parse_partial_symbols): Replace printf with complain.
2956 * i960-tdep.c: Fix copyright attribution.
2958 * config.gdb: Quote all backquotes in doublequotes. You can
2959 quote me on that. BSD 4.4 shell found this one.
2961 * infptrace.c (throughout): The third argument to ptrace is an
2964 * infrun.c (wait_for_inferior): When program has terminated, we
2965 have to call target_terminal_ours before we pop that target off
2966 the stack (e.g. before a call to target_kill or
2967 target_mourn_inferior). This fixes problem where a program
2968 terminates, then GDB stops for (tty output) and you have to type
2969 "fg" to the shell to resume it. FIXME: This code for what to
2970 do after termination really should be in normal_stop instead.
2972 * gdbcore.h (read_memory_check): Change declaration; it changed
2975 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
2976 4.4 prereleases, this avoids a bug in their sgtty compatability
2978 * remote.c: Use terminal.h rather than hand-rolling the same.
2980 * signame.c, signame.h (psignal): Arg is unsigned, not int.
2981 * utils.c (strsave, strstr): Fix arg types.
2982 * valprint.c (val_print): lint
2984 MIPS symbol table support from Per Bothner:
2986 * symfile.c (symtab_fns): Remove initializer table that needs to
2987 be hacked for each new symbol file format supported.
2988 (add_symtab_fns): New function, chains symbol table
2989 handlers into the global list.
2990 (symfile_init): Search this list.
2991 * symfile.h: Add next pointer, declare add_symtab_fns.
2992 * coffread.c (_initialize_coffread): Call add_symtab_fns.
2993 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
2995 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
2996 symbol *). Thus, we no longer need the hack to trash
2997 pst->filename. Good, since that hack confused code in symfile.c!
2999 (reorder_symtabs, destroy_all_symtabs): Removed static
3000 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
3001 Instead, the latter now uses a temporary array (stack-allocated
3002 from an obstack, and then freed).
3004 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
3005 haven't been set in the outermost stBlock of a procedure. This was
3006 a problem with f77 binaries on Ultrix 4.?.
3008 (new_symtab, new_symbol, new_type): Continue changing code to use
3009 obstacks more and otherwise conform to dbxread internal style.
3010 Made the free_code of symtabs be free_linetable (as in dbxread)
3011 instead of free_contents. This implies memory leaks when reading
3012 a new symbol table, until the conversion is finished. Did change
3013 (struct symbol) and (struct type) to be allocated on the
3014 symbol_obstack. Blocks and blockvectors are among the things
3017 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3018 tested much, but it solved one problem (reported by Meissner), and
3019 cleans up some other things. The problem happened when an
3020 included file contains actual code (functions) and not just
3021 definitions. The mips coff is a little inconvenient there, since
3022 it may cause a procedure to be mapped to the wrong psymtab.
3024 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3025 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3026 this will need work for the new core paradigm.
3028 Opcode patches from the net:
3030 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3031 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3032 missing altogether - they are added here. From Bruce Bauman.
3033 * mips-opcode.h: The low mask for C0 instructions was too small.
3034 From Garrett Lau. I modified the fix to check the entire 32-bit
3037 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3040 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3042 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3044 * dbxread.c (read_type): Pointer subtraction (value_sub in
3045 valarith.c) sometimes failed because the types of the
3046 pointers being subtracted were not identical.
3047 These differed because dbxread.c was allocating pointer types
3048 using dbx_alloc_type+smash_to_pointer_type instead of
3049 lookup_pointer_type. I failed to find a justification for the
3050 former, so I changed it to use the latter. Similarly, I
3051 replaced smash_to_function_type by lookup_function_type,
3052 and smash_to_reference_type by lookup_reference_type.
3054 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3055 _initialize_mipsread): corresponding changes.
3057 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3059 * source.c (mod_path): Do tilde_expand on each component of the path,
3060 rather than on the (list of) paths as a whole.
3061 (print_source_lines): Set first_line_listed in addition to
3062 current_source_symtab and current_source_line. If the source was
3063 not findable, after a "dir" command to fix the problem,
3064 a "list" would get the wrong lines.
3066 While I was there... (gnu):
3068 * dbxread.c (read_type): Change error to complaint.
3070 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3072 First attempt at detailed understanding of symbol table memory alloc.
3074 * dbxread.c (dbx_symfile_read): Free our string table if we
3075 aren't the mainline. Free the "info" struct since we're done with
3077 (init_psymbol_list): Free any previously allocated psymbol lists.
3078 (): FIXME: Should realloc-down the psymbol lists when done reading
3079 the main symbol file?
3081 * symmisc.c (free_symtab): Free fullname field too.
3083 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3084 (REGISTER_ADDR): Make result type unsigned int.
3086 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3087 define REGEX must also define REGEX1 (its dependency).
3089 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3091 * tconfig/i960: No longer works, points you at vxworks960 or
3094 * xgdb.c, XGDB-README: Remove file. Users can get the much
3096 * Makefile.dist: Remove all trace of xgdb.
3098 * breakpoint.c (breakpoint_1): Pass demangle arg to
3099 print_address_symbolic.
3100 (clear_breakpoints): Remove unused function.
3101 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3102 (breakpoint_re_set): Use catch_errors to do them all anyway.
3104 * gdb-int.texinfo (Host versus Target): Add section on what is
3105 a "host" feature versus what is a "target" feature.
3107 * infcmd.c (path_command, path_info): Handle the PATH variable
3108 (object search path) as conveniently as the source search path.
3109 * environ.c (set_in_environ): Set some vars in GDB's environment,
3110 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3111 * source.c (mod_path): New function, from guts of
3112 directory_command, modifies a path. Used by path_command.
3113 (directory_command): Call it.
3114 * defs.h (strsave): Declare.
3116 * utils.c (sevenbit_strings): Add new printing option.
3117 (printchar): Use it.
3118 (strsave): Provide this handy helper routine.
3119 (set_width_command): Rename set_screen_width_command.
3120 (_initialize_utils): "set screen-width" => "set width";
3121 "set screen-height" => "set height"; add sevenbit-strings.
3123 * infcmd.c (do_registers_info): Print floating point registers
3124 in raw hex as well as float format, regardless of whether it is
3125 a "virtual" convertible register.
3126 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3127 regs as a double, just in case it's being used that way.
3128 * values.c (unpack_long): Comment on array/function coercion.
3129 (unpack_double): Argument is in target byte order now. For
3130 integer arguments, just call unpack_long and float the result.
3131 * m68k-tdep.c: include defs.h for "const" handling.
3132 * remote-nindy.c: Use ieee-float stuff.
3133 (nindy_fetch_registers): Unpack double regs to host double, then
3135 (nindy_store_registers): Pack extendeds to host double, flip
3136 around by misusing unpack_double, send as target double.
3138 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3139 zero, as when stopped at the first instruction of a process.
3141 * blockframe.c: Fix filename in comment (param.h => tm.h).
3142 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3143 * tm-68k.h: Fix typos.
3145 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3147 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3149 * coredep.c (fetch_core_registers): Pass end-address of register
3150 section to register_addr as expected. Don't call supply_register
3151 if we'd just pass it garbage.
3153 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3155 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3157 * target.c (push_target, target_info): Cast enums to int for < or
3160 * stack.c (print_frame_info): Identify source file & line
3161 even if we can't print it.
3163 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3165 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3167 Clean up IEEE floating point support.
3169 * ieee-float.h: New file.
3170 * ieee-float.c: Write real routines to convert between host
3171 doubles and various target IEEE extendeds.
3172 * m68k-xdep.c: Eliminate assembler code for extended floats.
3173 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
3174 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3175 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3176 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3177 double_to_ieee_extended.
3178 * i960-tdep.c: Define ext_format_i960.
3179 * m68k-tdep.c: Define ext_format_68881.
3180 * sparc-tdep.c: Define ext_format_sparc, though unused.
3181 * Makefile.dist (HFILES): Add ieee-float.h.
3182 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3185 Obsolete the "coffstrip" program in favor of using BFD's strip.
3187 * nindy-share/coffstrip.c: Remove file.
3188 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3189 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3190 * tconfig/nindy960: Remove reference to coffstrip.o.
3192 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3194 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3196 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3197 * dbxread.c: Remove static symfile_bfd.
3198 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3200 * inftarg.c (child_detach): Pop the child_ops vector if the
3201 detach is successful.
3202 * remote-nindy.c (nindy_create_inferior): Don't push a new
3203 nindy_ops since nindy uses the same one for execution and memory
3205 * core.c (core_ops): Use child_attach and child_create_inferior
3206 rather than default attach and create_inferior functions.
3208 Handle floating point registers in core files.
3210 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3211 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3212 This version untested since BFD doesn't yet support sun3 core
3214 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3215 conventions. Fix comments and style. This version has not
3216 been compiled yet, since we have no HP inhouse.
3217 * core.c (get_core_registers): Look for two sections, ".reg"
3218 and ".reg2", and pass both to fetch_core_registers sequentially.
3220 Revise directory path yet again.
3222 * source.c (forget_cached_source_info): Not static any more.
3223 (init_source_path): New default source path is "$cdir:$cwd".
3224 (dir_command): Handle variable arguments ($cdir, $cwd).
3225 (source_info): Print "Compilation directory" rather than
3226 "Originally compiled in" to remind people of $cdir.
3227 (openp): If the path contains $cwd, use current directory.
3228 (open_source_file): If compilation directory is known, replace
3229 first $cdir in path with the compilation directory.
3230 (print_source_lines): Even if we can't print the lines, set the
3231 current symtab and line for future commands like "info source" or
3232 "breakpoint". Also, error message now contains the file name,
3233 line number, and file access error message.
3234 (_initialize_source): Fix help text to describe changes.
3235 * main.c (cd_command): Forget cached source info when we chdir.
3236 * utils.c (strstr): Add simple implementation.
3238 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3240 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3241 Byte-swap COFF symbol tables if necessary when reading them in.
3242 Use complain() to replace error message in one spot. Needs
3243 corresponding change in bfd/coff-code.h to make some symbol
3244 swapping routines non-static.
3246 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3248 Merge changes from Eirik Fuller, for UTek.
3250 * defs.h (errno): Add declaration.
3251 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
3252 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3253 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3254 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
3255 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
3256 declarations of errno.
3258 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3260 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3261 <rpc/rpc.h> and <rpc/types.h>.
3263 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3265 * i960-tdep.c (examine_prologue): Add new argument limit,
3266 which stops the scan at the end of the prologue, or at the PC.
3267 This fixes a problem where it walks down into the code for the
3268 user's statements if that code looks like function prologues.
3269 Mark Fox and I have been bouncing this code back and forth, making
3270 small changes to it. Callers changed to match.
3272 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3274 Cleanup for gdb-3.94 release final:
3276 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3277 the .c files from vx-share and nindy-share, from the various
3278 macros, since they are not found via ALLDEPFILES.
3279 (SFILES): Add tm-i960.h.
3280 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3281 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3283 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3284 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
3286 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
3288 * am29k-tdep.c: Add contribution line.
3289 (examine_prologue): Cache information about function prologues in
3290 the misc-function-vector to avoid lots of references over the
3291 serial line while examining instructions.
3293 * core.c (core_close): New function made from cleanup_core.
3295 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3296 remote-vx.c, remote.c, target.c, target.h,
3297 Update target_ops vector to add attach, close, and load entries.
3298 Use add_syms_addr_command, not add_file_addr_command, for
3299 add_file. Break out close routine from existing code.
3301 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3302 they are in an obstack.
3303 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3305 (define_symbol): Add symbol type parameter; change callers;
3306 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3307 it to influence the symbol class on the i960.
3308 (define_symbol): Swap LOC_CONST's into target byte order.
3310 * exec.c (exec_close): New function.
3311 (exec_file_command): Call it.
3313 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3314 Fix byte order of frame pointer.
3315 (read_var_value): Result of 0 if var's value can't be found,
3316 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3317 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3318 (locate_var_value): Use read_var_value and use its lazy address
3319 as the location of the var's value. Lint.
3321 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3324 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3325 obsolete Intel versions in favor of vxgdb versions.
3326 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3327 code dealing with byte order of values, which Intel did in host byte
3328 order rather than gdb-4's target byte order.
3329 (i960_frame_chain_valid): Move to nindy-tdep.c.
3330 (examine_prologue, skip_prologue, frame_find_saved_regs,
3331 frame_args_address, leafproc_return, saved_pc_after_call,
3332 pop_frame): Add vxgdb versions from Mark Fox.
3333 (examine_prologue, frame_struct_result_address): Add code
3334 to deal with the saved value of G13 (struct return address
3336 (frame_args_address): Modify Mark's version to prefer the
3337 saved value over the current value in the topmost frame.
3338 Cache result in the frame info to avoid performance hair in
3340 (print_fault): Add gdb960 code for printing faults.
3341 (_initialize_i960): Actually call check_host.
3343 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3344 add stub routines. FIXME, these currently just return zero!
3346 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3347 (attach_command): Call target_attach, not target_open, now.
3349 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3350 (child_attach): Rename from child_open.
3351 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3352 don't confuse it with a zero step_resume_break_address.
3354 * inftarg.c (child_detach): Eliminate inferior_pid test.
3355 (child_files_info): Clean up message a bit.
3356 (child_ops): Use child_attach, not child_open, to attach.
3358 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3359 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3360 findvar.c to here, since it depends on the contents of the
3361 shadow_contents of breakpoints, but keep if #if 0 since it is
3364 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3367 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3368 (ptype_command, display_command): Eliminate have_inferior_p and
3369 have_core_file_p in favor of target_has_stack or
3370 target_has_execution.
3371 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3372 code for actually finding the values of arguments, though we still
3373 keep track of the maximum stack offset for use in printing unnamed
3374 arguments. Handle missing FRAME_ARGS_ADDRESS.
3376 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3377 (struct nindy_regs): Define registers passed to/from nindy.
3378 (nindy_fetch_registers, nindy_store-registers): Translate between
3379 nindy and GDB formats for the registers.
3380 (dcache_init): Statically allocate the cache, since it was being
3381 allocated by a malloc that was never freed anyway.
3382 (nindy_create_inferior): Error, not core dump, if no exec file.
3383 (nindy_before_main_loop): Use target_load, not target_add_file.
3385 * remote-vx.c (net_load): Specify large timeout for load
3386 requests. Allow user to break out with INTERRUPT.
3387 (net_break): Remove useless code, clean up. Change callers.
3388 (parse-args, skip_white_space, find_white_space): Clean up arg
3389 parsing to cope with quoted strings.
3390 (net_wait, net_quit): Never call error, just return status.
3391 (vx_read_register, vx_write_register): Cleanup status checking.
3392 #ifdef the code based on which CPU we are using (960 or 68k),
3393 FIXME, this should be completely general but it isn't yet.
3394 (vx_xfer_memory, vx_resume): Cleanup status checking.
3395 (vx_run_files_info): Improve message.
3396 (vx_load_command): Renamed from vx_add_file_command. Allow load
3398 (net_ptrace): Remove unused routine.
3399 (vx_wait): Adopt code from vxgdb960 to cope with broken
3400 connections to target machine and prompt to disconnect. Remove
3401 debug printouts. Map some EVENT_'s to SIGnals.
3402 (add_symbol_stub, vx_open): Print names of object files we found,
3403 and "ok" if we read their symbols OK. Clarify output in general.
3404 (vx_attach, vx_detach, vx_kill): Add these commands.
3405 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3406 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3407 "info files" output, and create_inferior, since we already have
3410 * stack.c (frame_info): Replace Frame_unknown with 0.
3411 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3412 (return_command): Pop until the PC matches as well as the FP,
3413 so it works even if the FP is shared with another function,
3414 as in "frameless" or "leaf" procedures.
3416 * symfile.c (load_command): renamed from add_file_target_command.
3417 (add_syms_addr_command): renamed from add_file_addr_command.
3418 (add_syms_command): Stub to call target_add_syms.
3419 (_initialize_symfile): Change command names and descriptions,
3420 add-file => add-syms, and load from alias to its own command.
3422 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3423 maybe_kill_then_create_inferior): Default for attempts to start
3424 a process, if one is already running, is to ask about killing
3425 it and retry if yes.
3426 (upstack_create_inferior): #if-0 it, strata obsolete it.
3427 (push_target, unpush_target, pop_target): to_close() a target
3428 before unstacking it.
3429 (target_info): Renamed from target_files_info.
3430 (_initialize_targets): Rename "i files" as "i target", accessible
3433 * target.h: Improve comments about the target_ vectored routines.
3435 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3436 Convert commenting style to standard GNU style.
3437 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3438 (SKIP_PROLOGUE): No longer a no-op.
3439 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3440 (*_REGNUM): Sort register numbers.
3441 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3442 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3443 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3444 are now 10 byte extendeds, not 8 byte doubles.
3445 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3446 for nindy versus vxworks targets. FIXME, this should possibly go
3447 in the target vector.
3448 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3449 frame_saved_regs and arg pointer with each frame.
3450 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3451 (FRAME_ARGS_ADDRESS): Use cached result.
3452 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3453 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3454 (PRINT_RAMDON_SIGNAL): Call print_fault.
3455 (POP_FRAME): Now works.
3457 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3458 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3459 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3460 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3463 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3464 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3466 * valarith.c (value_subscripted_rvalue): Avoid handling
3467 floats and doubles specially; it gave alignment errors. Lint.
3469 * valops.c (value_of_variable, value_of_this): Error if unknown
3472 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3473 to avoid alignment problems.
3474 (value_print): Handle unknown value address.
3475 (cplus_val_print): Two args are ignored; remove them. Change caller.
3476 (val_print): Use unpack_long rather than pointer-deref.
3479 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3480 to avoid alignment problems.
3481 (value_being_returned): Error if return value unknown.
3482 (set_return_value): Add bogosity warning, FIXME. *
3484 * TODO: A woman's work is never done.
3486 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3487 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3488 Add ieee-float.o to OBS.
3489 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3490 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3491 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3493 Changes to generalize the VxWorks RPC protocol slightly, to handle
3494 i960 as well as 68000.
3496 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3497 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3498 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3499 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3500 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3501 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3502 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3503 so they will move in target byte order rather than network
3504 byte order (happens to be the same).
3506 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3508 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3510 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3513 Add contribution lines to various files, showing where they
3516 * breakpoint.c (break_insn, check_break_insn_size,
3517 read_memory_nobpt): Remove to mem-break.c.
3519 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3522 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3523 entry has bad register number. This change is not
3524 tested in this release, FIXME.
3526 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3529 * value.h: Force value's contents field to be aligned to hold
3530 at least a double or a long long (if supported). This avoids
3531 doing bcopy's in and out of the contents field.
3533 (step_1): Avoid coredump under obscure circumstances when we
3536 * symtab.h (misc_info): Add field to misc function vector for
3537 any kind of cached information the target code desires. AMD
3538 29000 uses this to avoid repeating examine_function_prologue's.
3540 * coffread.c: Lint. Remove static symfile, read_section_header.
3541 core.c (have_core_file_p): Lint: remove.
3542 expprint.c (print_subexp): Lint.
3543 infptrace.c, valops.c, valprint.c: lint.
3545 Roll in changes from vxgdb-5.0.1:
3547 * symtab.h: Comment byte order of each address class. Add
3548 LOC_LOCAL_ARG for frame-relative args (960).
3549 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3550 symtab.c, symmisc.c: ditto.
3552 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3554 * remote.c (remote_resume): Error if resume with a signal.
3556 * symfile.c (prim_record_misc_function): Clear misc_info.
3557 (fill_in_vptr_fieldno): Check stub type of arg.
3559 * valops.c (value_cast): Avoid looking up names of types whose
3560 name we don't know, to prevent coredump. Sun CC produces typedef
3561 rtx and the name of *rtx is zero...
3563 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3565 Roll in changes from final AMD 29000 port (Tiemann).
3567 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3568 for ../include/a.out.encap.h. This might not work now that BFD
3569 is separately compiled. Instead, BFD support for encap will have
3570 to translate machine type 29k into the right COFF_MAGIC.
3572 * infcmd.c: Remove references to inferior_pid that aren't used
3573 in actual ptrace calls; use target_has_execution, etc.
3574 (have_inferior_p): Remove function.
3575 (program_info): Print target info rather than "process number";
3576 avoid gratuitous messages unless from_tty.
3577 (run_stack_dummy, finish_command): Set proceed_to_finish.
3578 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3579 main.c: Lint. Lose have_inferior_p().
3580 inferior.h (have_inferior_p): Remove, lint.
3581 (proceed_to_finish): Add flag to ask that all regs be saved
3582 by normal_stop, for the few commands that need it, speeding up
3583 serial I/O. Add comments to stop_registers.
3585 * remote-eb.c: Remove newline from breakpoint message we grep
3586 for. Never time out when running the user program.
3590 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3592 Roll in changes from vxgdb-5.0.1:
3594 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3595 symbol in its raw form, we are processing an unlinked ".o" file.
3596 See if the target environment has assigned it an address, using
3597 target_lookup_symbol (VxWorks does), and enter it into the symtab
3600 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3601 68k versions for a simpler version that assumes zero FP at bottom.
3602 Fixes bug of truncated stack reports.
3604 * target.h (target_lookup_symbol): Define this routine's args
3605 and result, finally.
3607 * target.c (nosymbol): Default routine for target_lookup_symbol.
3608 (target_default): Default lookup_symbol and call_function too.
3609 (files_info): Only print has_all_memory warning if a non-dummy
3612 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3613 vx_convert_from_virtual): If target does not have floating point,
3614 zero register "values", and avoid doing cross-net conversions.
3615 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3616 (vx_open): Rearrange code that attaches to target and reads
3617 symbols for all loaded modules, to work if some of the modules
3618 are not accessible. Add symbol_stub() and add_symbol_stub()
3619 as callbacks from catch_errors(). Allow connect attempt to be
3620 interrupted painlessly with ^C (FIXME, there are still some bugs
3621 if the interrupt happens during symbol reading.). Print
3622 final message with puts_filtered, since symbol messages are
3627 * main.c (catch_errors): Only print errstring if non-null.
3628 (command_loop): Avoid an ioctl per command to test ISATTY.
3630 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3631 (vx_xfer_memory): Return correct result!
3632 (vx_files_info): Indicate whether target has float or not.
3633 (vx_lookup_symbol): Complain, not error, if target gone.
3634 (vx_open): Print "Connected" msg before disabling immediate-quit.
3635 [FIXME: lookup_symbol and vx_open changes need testing.]
3637 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3638 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3639 contributor lines and update copyrights to 1991.
3641 Changes from an attempted H-PUX host port:
3643 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3644 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3645 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3646 * remote-vx.c: include <sys/time.h> for HPUX.
3647 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3648 "core_file_command" routine to BFD regime. May not work yet.
3650 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3652 * xgdb.c: Replace X10 version with some VJ version.
3653 (FIXME: Its copyright assignment is not on record.)
3654 * xgdb.c: Update include files to X11R4 (Xaw crud).
3655 (xgdb_display_source, create_text_widget): fix call to
3656 get_filename_and_charpos. Rewack source window stuff for X11R4
3657 (gleaned from include files, and "nm's" of binary libraries, since
3658 I had no doc available).
3659 (append_selection, append_selection_word): Disable with FIXME
3660 since R4 changed interface here.
3661 (create_buttons): Add back the old set of buttons.
3662 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3664 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3665 Roll VERSION to 3.94 (not yet final though).
3667 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3669 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3670 obstack_int_grow, obstack_int_grow_fast): Eliminate
3671 cast on left of assignment, which gives MIPS cc fits and is
3674 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3675 F_ALIAS. Use printf, not fprintf, when not passing a file
3677 (compare_opcodes): Check that identical instructions have
3678 identical opcodes, complain otherwise.
3680 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3681 was reported by Roland McGrath.
3682 (unimp): Only match if exactly zero instruction. (Roland)
3683 (branches and traps): Generate all variations of these
3684 instructions with macros, based on a single call that defines
3685 each condition name and its binary representation.
3686 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3688 * valprint.c (val_print_fields): Take, and use, format parameter.
3689 This means that "p/x struct" again prints the elements in the
3690 desired format. Changed callers.
3692 * stack.c (frame_info): Use filtered output, and indicate wrap
3693 points. Remove kludgy formatting designed to avoid line wrap.
3695 * utils.c (wrap_here): If the line is already full (because
3696 we had printed a long indent or long wrapped string), do an
3697 immediate newline-and-indent.
3699 * m68k-pinsn.c (print_insn_arg): Bugfix from
3700 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3701 instruction is incorrectly disassembled as bkpt #8.
3703 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3704 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3705 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3706 and then will dump core (sometimes). I traced it back to an
3707 uninitialized symfile_name in psymtab_to_symtab.
3708 (const_vol_complaint): Add quotes to message.
3709 (define_symbol): Only believe line number if gcc_compiled.
3710 Avoid allocating symbol if we will not return it.
3712 Add target strata support so that newly established targets go
3713 into their right place in the target stack (e.g. a new exec file
3714 doesn't wipe out the ability to access the running process).
3716 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3717 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3718 and initialize it properly in all the targets.
3720 * target.h: Document strata. Change return type of push_target.
3722 * target.c (nomemory): new function for dummy memory access.
3723 (tcomplain): Rename complain, now also used in symfile.c.
3724 (push_target): Push targets within strata. New return value shows
3725 whether new target is on top of stack or not. Always keep dummy
3727 (target_files_info): Ignore dummy target.
3729 * core.c (core_open): Warn user, and skip accessing file, if the
3730 core target is not the topmost target in the stack.
3731 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3734 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3735 target_ops, it doesn't belong there since we have no regs there.
3736 Change name of target from machine => memory to clarify.
3738 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3740 * Freeze version 3.93 for release.
3742 * Makefile.dist: Handle vx-share and nindy-share subdirs
3743 properly when building gdb.tar.Z.
3745 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3746 printed in various places, so I could change just one copy.
3748 * dbxread.c, coffread.c: Change references to bfd->iostream
3749 to cast to FILE *, now that BFD avoids needing types defined
3750 in other header files.
3752 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3754 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3755 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3756 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3757 (actually gcc -Wall).
3759 * dbxread.c: Remove first_global_sym, last_global_sym, since
3760 they are never referenced.
3762 * defs.h (baud_rate): Declare.
3763 main.c: Define it, and add the -b option to set it.
3765 * gdb-int.texinfo: Add text on how to define a new host or target
3766 architecture, prompted by Per Bothner's questions about MIPS
3769 * gdb.texinfo: Document "complaints". Change doc of -q since
3770 gdb no longer prints the copyright and blurb if you specify a file
3771 name to be debugged (just like Emacs). Add doc for Nindy-specific
3772 command line flags for specifying target serial port and such.
3773 Update copyright to 1991.
3775 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3776 has taken over for us the job of ripping up executable files. The
3777 crud caused Per Bothner's port to not compile.
3779 * infrun.c (normal_stop): Avoid printing "Program exited
3780 normally" if we are in batch mode. This allows a GDB which
3781 executes a program on a target system, to behave like a Unix
3782 command (input from stdin, output to stdout, no extraneous
3785 * main.c (main): Allow additional machine-dependent command line
3786 options to be specified with the ADDITIONAL_OPTIONS,
3787 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3788 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3789 processing to occur just before the main loop with
3790 BEFORE_MAIN_LOOP_HOOK.
3791 (main): If a "core file" argument is specified, and it is not a
3792 core file, try it as a process ID to attach.
3793 (symbol_completion_function): Attempt to cope with
3794 "show screen-" TAB, not very successfully. This needs more work,
3796 (batch_file): New function, returns whether we are reading
3797 commands from an interactive tty on stdin, or from somewhere else.
3798 Called by normal_stop since it doesn't get from_tty passed down
3799 to it like many commands do.
3801 * remote-nindy.c: Handle command line options for nindy
3803 (nindy_before_main_loop): Prompt user for tty name if they
3804 don't specify it before getting to the interactive command loop.
3806 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3807 and -r command line options. Also add hook before main loop
3808 to make it easy to specify a tty.
3810 * TODO: More things to do, one done.
3812 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3814 * dbxread.c: Make complaint() calls pass pointer, not struct.
3815 Add complaints about badly formatted C++ type information
3816 (const/volatile indicator, and parse errors resulting in
3817 error_type). Fix C++ virtual member fn comment.
3818 (read_struct_type): Avoid bumping pointer if we got a parse
3819 error; this prevents our walking beyond the end of a string.
3820 Terminate loop on null char as well as semicolon.
3821 (process_one_symbol): Fix the LBRAC fix so that it uses the
3822 last previous SLINE, FUN, or SO record's PC address. C++ debug
3823 symbols did not have SLINE records in a useful order compared
3824 to the LBRAC records.
3825 (define_symbol): Handle "catch" records.
3827 * symtab.c (check_stub_type): Added new complain
3828 `stub_noname_complain' and added a consistency check to
3829 keep the debugger from crashing when finishing from an
3830 exception frame. A real fix will be needed later.
3832 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3834 * infcmd.c (attach_command): Make global.
3836 * Makefile.dist (REMOTE_OBS): Make these compile by default,
3837 but make them easy to comment out. Perhaps later they should
3838 be enabled by what CPU you configure for? FIXME.
3839 (VERSION): Roll to 3.93.
3840 (pinsn.o): Remove rule for obsolete file.
3841 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
3843 Run down a problem that manifested by printing the wrong function
3844 name in stack traces of read_ofile_symtab. Turned out that the
3845 problem was the SunOS 4.1.1 (and previous) C compiler outputs
3846 the LBRAC symbol with an address in the *data* segment, which
3847 blew our binary search through the blocks.
3849 * dbxread.c: Use the complain() facility consistently to bitch
3850 about problems in the symbol file we are reading.
3851 (finish_block): Add code to check the nesting of the blocks;
3852 complain and Procrust them to fit if wrong.
3853 (make_blockvector): Check the order of the blocks, complain
3854 [but don't cope] if wrong.
3855 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
3856 symbols to be sure their PC value is greater than the last SLINE
3857 (line number) symbol we've seen, complaining and adopting the
3858 SLINE PC value if wrong.
3860 * symfile.h (struct complaint, complaint_root, complain,
3861 clear_complaints): Add.
3862 * symfile.c (complain, complaint_root, clear_complaints): Add
3863 facility to deal with non-fatal complaints and to regularize their
3865 (symbol_file_add): Clear complaint counters to allow new complaints.
3866 (initialize_symfile): Add 'set complaints' and 'show complaints'.
3868 * dbxread.c (dbx_symfile_read): Remember the address and size
3869 of the string table for the main symbol file, so we won't read it
3871 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
3872 to avoid reading the string table yet again. Lint.
3873 (throughout): Improve filtered output, including word wrap.
3874 (read_range_type): Improve Bothner's fix to handle other types too.
3876 * utils.c: Improve line wrap implementation. Handle unlimited
3877 width by making chars_per_line unsigned.
3878 (puts_filtered): New, easy, function.
3880 * defs.h (puts_filtered): add.
3882 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
3883 call the identical sort_symtab_syms() in symfile.c instead.
3885 * expread.y: Suggest the `file' command rather than `symbol-file'.
3887 * command.h (enum var_types): Add zinteger for seroable
3889 * command.c (do_setshow_command): Handle var_zinteger. Restructure
3890 nested if's into a switch.
3892 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
3893 we did not stop because of a breakpoint (it must have been for
3894 some other reason, like a "stepi"), so don't print anything.
3896 * symtab.c: Include <sys/types.h> all the time. Now that BFD
3897 doesn't include <sys/types.h>, old SunOS's require it for
3900 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
3902 A test port of gdb-3.92.6 to the Sony NEWS.
3905 Don't normally link in remote- or vx stuff.
3906 Some of it doesn't compile, and it wastes space for 99% of the users.
3907 Remove reference to no-longer-used HAVE_VPRINTF.
3908 Fixed BFD_DEP typo to BFD_DIR.
3910 Fix cast in arg to bfd_h_getlong.
3911 Make char *prefix be const.
3912 Fix how certain range types are mapped into builtin unsigned int types.
3914 Remove 2 #includes. They cause errors (on Sony, at least),
3915 and aren't needed (they wern't in earlier versions).
3917 print_address_symbolic should never demangle labels
3918 (since it prints *assembler-level* labels).
3920 [This was superseded by the change to printcmd below.]
3923 Add some "volatile" return types to avoid warnings.
3924 If MISSING_VPRINTF add vprintf function and not just macro
3925 (since vprintf is used in printcmd.c).
3927 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
3928 (The latter isn't grokked by some PCC-based compilers.)
3930 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
3932 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
3933 * nindy-share/coffstrip.c
3934 Added some forward declarations (otherwise, gcc complains
3935 about implicit extern redefined as static).
3937 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3939 Changes inspired by Per Bothner:
3940 * printcmd.c (print_address_symbolic): Take additional parameter
3941 specifying whether to demangle.
3942 (print_address): Pass in asm_demangle to control demangling.
3943 (print_address_demangle): New fn, takes explicit arg to control
3945 * utils.c: Add new vars demangle and asm_demangle, and let them
3947 (fputs_demangled): If !demangle, just print the argument.
3948 (fprint_symbol): If !demangle, just print raw symbol.
3949 * valprint.c (val_print): Call print_address_demangle rather than
3950 print_address, to cause demangling to depend on the global
3951 rather than assembler-level demangling setting.
3952 * WHATS.NEW, gdb.texinfo: Document.
3954 * main.c (show_command): Show all settings if no arg.
3955 (initialize_main): Make "info set" the same as naked "show".
3956 * command.c (cmd_show_list): Handle prefix commands in the
3957 list, and print the name of the setting as well as its English
3958 description and value.
3960 Allow gdb functions to specify where a line should wrap if it
3961 exceeds the size of a terminal line. Use it to make the output
3963 * utils.c (set_screen_width_command): New fn, mallocs a buffer
3964 of the right size when screen width changes.
3965 (set_screensize_command, screensize_info): Remove #if 0'd fns.
3966 (wrap_here): New fn, indicates a point in the output where we
3967 should wrap the line rather than just letting it overflow at a
3969 (fputs_filtered): Implement wrapping.
3970 (n_spaces): New fn, returns a pointer to N spaces.
3971 (print_spaces_filtered): Use n_spaces.
3972 * defs.h (n_spaces): Declare.
3973 * stack.c (print_frame_info): Wrap with 4-space indent after
3974 fn name and before filename and line number.
3975 * printcmd.c (print_frame_args): Wrap with 4-space indent
3976 before each argument name is printed.
3977 * valprint.c (value_print): Wrap with no indentation before
3979 (val_print_fields): Wrap with indentation relative to nesting
3980 level before each field name.
3981 (val_print): Wrap with nesting indentation before array elements.
3982 * command.c (do_setshow_command): Avoid extra newlines,
3983 wrap with 4-space indent around values printed, end with period.
3984 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
3986 * breakpoint.c (breakpoint_1): Implement addressprint for
3987 "info breakpoints" display. Change file name and line number
3988 format to " at file:nnn" rather than " (file line nnn)".
3989 * gdb.texinfo: Document.
3992 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3994 Frozen for gdb-3.92.6 release.
3996 README, WHATS.NEW: Update for 3.92.6 release.
3998 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
3999 coffread.o from configs since it is now built by default.
4000 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
4001 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
4002 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
4003 from configs since it is now built by default.
4005 Makefile.dist: Update for release 3.92.6. Handle files that
4006 have been moved to ../include, ../getopt, or ../bfd. Add
4007 saber.suppress and tests directory. Add config.status to
4008 the release (it will say "none").
4010 coredep.c: Minor formatting fixes.
4012 These changes were made in early December but only checked in now:
4013 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4014 nindy-share/nindy.c: lint
4015 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4016 register values coming back from the target; we store values
4017 in target byte order everywhere.
4019 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4021 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4023 * valprint.c (cplus_val_print, val_print_fields): New functions,
4024 which print C++ objects. They conspire to avoid printing a
4025 virtual base class more than once, following all the twists and
4026 turns of C++ virtual base rules.
4027 (val_print): Call the above rather than do it by hand.
4029 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4030 symbol file, not for added files like shared libs. This really
4031 needs to be generalized to a timestamp per file.
4033 * core.c (cleanup_core): Avoid coredump if no core file.
4035 * config.gdb: Accept -host or -target in place of +host or
4038 * coffread.c (find_linenos): Avoid desupported BFD interface
4039 to line numbers. We still read them manually rather than using
4040 BFD's "generic" features.
4042 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4044 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4046 * Makefile.dist: Eliminate use of $< in explicit targets.
4048 * readline/Makefile: Use $< rather than $*.c, which does not
4049 include the VPATH in GNU Make.
4051 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4052 copies of tconfig/i960, added for global configuration
4053 compatability. All i960 versions can read both coff and b.out.
4055 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4056 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4059 * TODO: Think of more things to do.
4061 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4063 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4064 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4065 64-bit float conversion.
4067 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4068 equivalent to sun?os4 so global config works.
4070 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4072 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4074 * main.c: Only declare linesize once; declare pagesize not at
4075 all, since it is never used.
4076 (main): Clear newly allocated line before it is used.
4078 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4080 Further stabilization for the Intel 960.
4082 * Makefile.dist: Parameterize the location of the "include"
4083 and "bfd" directories, as well as "getopt". Add symfile.c.
4084 Link in both dbxread and coffread. Fix up "make depend" to
4085 rewack the locations of include, bfd, and getopt in its output.
4087 * README: Document moving include files, improve some of
4090 * coffread.c: Move common code out to symfile.c. Change
4091 symbol_file_command style interface to use new *_symfile_init
4092 and *_symfile_read interface under BFD. Use BFD internal
4093 info to locate line table, symbols, etc.
4095 * core.c (core_fetch_registers): Rename to get_core_registers
4096 to avoid confusion with fetch_core_registers.
4097 (register_addr): Move to coredep.c, which is already machine
4098 dependent. This leaves core.c pretty clean of dependencies.
4100 * coredep.c (register_addr): Accept this routine from core.c.
4102 * dbxread.c: Move common code (with coffread.c, etc) into new
4103 symfile.c. Each psymtab now contains a pointer to the
4104 format-dependent function that knows how to read it in. Make
4106 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4107 (process_one_symbol): Add code to complain about a "compiler bug
4108 we muzzle here", if we actually see it.
4110 * eval.c (evaluate_subexp): Insert missing "break" statements
4111 in code that determines whether a variable is an lvalue in
4112 memory, register, or whatever. I detected this via a compiler
4113 bug in which it *almost* mashed out the whole switch statement.
4115 * gdb-int.texinfo: Add minor sections on configuring gdb for
4116 release, and about the README file.
4118 * infcmd.c (registers_info): Fix formatting somewhat. Still
4119 not as pretty as before, but it handles byte swapping.
4121 * remote-nindy.c: If data cache routines are interrupted while
4122 waiting for the remote end, be sure that any uninitialized cache
4123 blocks are on the free list, not on the valid list!
4125 * symfile.h: Flesh out this header file with all the various
4126 routines and variables that have been merged in from dbxread.c
4127 coffread.c, and symtab.c to symfile.c.
4129 * symfile.c: New file, containing code common to dbxread.c,
4130 coffread.c, and some code from symtab.c. All generic code for
4131 reading symbol files should be in here now.
4132 (unrecord_misc_function): Remove unused function.
4134 * symtab.h: Remove file-reading things to symfile.h.
4136 * symtab.c: Remove file-reading things to symfile.c.
4138 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4139 to decode i960 fault types.
4141 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4142 target.c: Change type of the "resume" function from int to void,
4143 since its result was never used.
4145 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4147 * main.c: Replace "stupid" with "caution"; you now "set caution
4150 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4152 * infcmd.c (do_registers_info): Call val_print to deal with the
4153 byte order of the registers being printed. FIXME, this makes
4154 the formatting of the output uglier.
4156 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4157 defined, call it for signals the debugger doesn't itself use.
4158 The i960 uses this for more detailed fault information.
4160 * remote.c (remote_open): If arg is null, print help rather than
4163 * sparc-xdep.c (register_valid): Avoid declaring size, since
4164 various modules will think of various sizes depending on the
4165 architecture of their tm-file. FIXME, we need protection against
4166 actually entering one of those modules, which would clobber
4167 storage if not for the target architecture compiled into gdb.
4169 * stack.c (up_command, down_command): Always print the frame
4171 (up_silently_command, down_silently_command): New commands
4174 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4176 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4177 more parameters than it used to.
4179 * findvar.c (registers): Increase slop to 256 bytes, which should
4180 protect us against even most RISC machines with large register
4182 (locate_var_value): Move declaration inside related ifdef.
4184 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4185 throughout, to avoid throwing away buffered input from the board.
4186 (nindy_wait): Supply_register takes addr_of_value, not value.
4187 (i960_print_fault): Renamed from i80960_fault.
4188 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4189 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4191 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4192 we can set the PC in the call to proceed(). Unpush nindy_ops
4193 before pushing it on top, to avoid message to user. Eliminate
4194 commentary from Unix machines that just misleads here.
4195 (reset_command): Fix error message to suggest target command.
4197 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4199 Release 3.92.5 as frozen.
4201 Stabilize the merged release...with help from lint, Saber C,
4204 Everywhere: Add include files needed to declare return types
4205 of functions called.
4207 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4209 * breakpoint.h: Add undeclared breakpoint functions, and some
4210 functions for display handling since I couldn't think of a better
4213 * breakpoint.c (insert_breakpoints): Make code for disabling
4214 shared library bkpts more likely to work. It's used when we
4215 rerun a program and stop before the shared library has been
4217 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4218 cast from pointer, so it squeezes through catch_errors.
4219 (bpstat_stop_status): Fix logic broken some time ago. We now
4220 always create a bpstat if the stop address matches a breakpoint,
4221 even if we don't stop there -- just like the old code used to do
4222 before I got my fingers into it (sigh).
4223 (breakpoint_1): Print "ignore count" after "stop only if"
4224 condition, since that's how it actually works.
4225 (mention): Handle watchpoints as well as breakpoints.
4226 (watch_command): use set_raw_breakpoint and mention to do most
4227 of the work (and initialize all the fields!). Only pass one
4228 arg to parse_c_expression, since that's all it takes.
4230 * command.c (not_just_help_class_command): Rename arg to args
4231 since we ignore "unused argument" warnings on vars named "args".
4232 inflow.c (child_terminal_info): ditto.
4233 infptrace.c (kill_inferior): ditto
4234 main.c (catch_errors, version_info, quit_command, pwd_command,
4235 source_command, dump_me_command, editing_info,
4236 set_history_size_command, set_history, show_history,
4238 stack.c (locals_info): ditto
4239 target.c (target_files_info): ditto
4240 valprint.c (set_input_radix, set_output_radix): ditto
4242 * core.c: Remove old variables for handling core and exec file
4243 sections (data_start, data_end, stack_start, stack_end,
4244 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4245 text_end, exec_data_start, exec_data_end, text_offset,
4246 exec_data_offset, data_offset, stack_offset). They're
4247 superseded the more general build_section_table and
4249 (get_exec_file): Mention the `file' command.
4250 (read_memory_check): Rename to memory_error, and only call it
4251 in the case of an actual error.
4252 (read_memory, write_memory): call memory_error.
4253 (core_fetch_registers): Register section name is ".reg".
4255 coredep.c: Remove a bunch of crud now that all this file does
4256 is pull the registers out of a core file.
4257 (fetch_core_registers): Rewrite to actually work, I hope.
4259 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4260 Replace index() with strchr(). Remove all the pre-BFD macro
4261 definitions for accessing the symbol file.
4262 (struct dbx_symfile_info): Encapsulate the information that
4263 dbx_symfile_init needs to pass to dbx_symfile_read in this
4266 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4267 dbx_symfile_discard): Rearrange symbol file reading to divide
4268 the format-specific part from the format-independent part,
4269 leaving the format-independent part such as file name expansion
4270 and opening in symtab.c. This replaces
4271 partial_symbol_file_open and partial_symbol_file_read.
4272 Symbol_file_read, add_file, add_file_target_command,
4273 add_file_addr_command move to symtab.c. Pass an explicit
4274 "mainline" flag for when reading the main symbol table, rather
4275 than relying on the offset address to be zero or nonzero.
4277 (dbx_symfile_read): Don't allow void *'s to be printed as
4279 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4280 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4281 macro" debug version really work.
4282 (read_dbx_symtab): Remove unref'd parameter inclink.
4283 Avoid swapping N_SLINE symbols, for speed.
4284 Merge N_TEXT!N_EXT case with the other external symbol
4285 definitions' case. Add comments.
4286 (start_psymtab): Allocate the symfile name in the psymtab on
4287 the psymbol_obstack, rather than using the caller's storage.
4288 (end_psymtab): Only allocate a dependencies list if there are
4290 (psymtab_to_symtab_2): Use BFD when reopening file to read
4291 its symbols for real.
4292 (read_struct_type): Add FIXME comments where it needs work
4294 (read_huge_number): Add FIXME about overflows.
4295 (read_range_type): Add FIXME about comparing a long to 1<<32.
4297 * coffread.c: Minor changes to move things closer to the new
4298 regime with symtab.c and dbxread.c Major work is still needed
4301 * exec.c (exec_file_command): Remove old variables (see core.c
4303 (xfer_memory): If memory transfer is right at the end of a
4304 section, don't lose.
4306 * findvar.c (get_saved_register): If value is in a real
4307 register, LVAL is lval_register, not lval_memory.
4309 frame.h: Declare print_sel_frame and record_selected_frame.
4311 gdb-int.texinfo: New file, for GDB internals documentation.
4312 Very simple, unformatted doc of cleanups is there for now.
4314 gdbcore.h: Remove obsolete variables that described a.out
4315 section addresses and offsets. (See core.c above.)
4316 Declare fetch_core_registers and registers_fetched.
4318 getopt.c: Declare char *alloca(); even on SPARC.
4320 infcmd.c (run_command): Call target_kill rather than
4322 (step_command, next_command, stepi_command, nexti_command):
4323 Declare from_tty parameter even though we don't use it.
4324 (run_stack_dummy): argument BUFFER is a char array, not
4325 a pointer to REGISTER_TYPE.
4326 (finish_command): using_struct_return needed a value *,
4327 not a struct symbol *.
4329 * infptrace.c (child_xfer_memory): To avoid dependency on
4330 where sections are in memory, try PT_WRITE_D and if that fails,
4331 try PT_WRITE_I. Most Unixes don't care which you use.
4333 * infrun.c (step_resume_break_shadow): Change to array to
4334 match other breakpoint shadow storage.
4335 (clear_proceed_status): Pass address of bpstat to
4336 bpstat_clear, not the bpstat itself.
4337 (child_create_inferior): FIXME comment about if the child
4339 (start_inferior): Remove old function.
4340 (child_open): Use target_kill rather than kill_inferior.
4341 (wait_for_inferior): Ditto.
4342 (insert_step_breakpoint, remote_step_breakpoint): Use
4343 new step_resume_break_shadow.
4345 * inftarg.c (child_wait): If all child processes die,
4346 pretend that the one being waited for exited with signal 42.
4348 * main.c (command_line_input): When scanning for comments,
4349 don't coredump on unclosed quotes.
4350 (quit_command): Use target_kill rther than kill_inferior.
4351 (_initialize_main): Rename class_user from "user" to
4354 * printcmd.c (print_command_1): Initialize "fmt" if no format
4355 is specified by the user.
4356 (print_frame_args): Only add to args_printed if we are
4357 actually fetching args from the stack (avoiding undefined
4359 (_initialize_printcmd): Remove bogus \{ from string.
4361 * remote-eb.c (eb_open): Avoid coredump on no argument.
4363 * remote-nindy.c: Bring out of Intel environment into new
4364 target environment. Remove all conditional compilation on
4365 I80960. Massive hacking throughout.
4366 (nindy_xfer_inferior_memory): New routine stolen from
4368 (nindy_create_inferior): New routine pieced together, probably
4369 not quite working yet.
4370 (nindy_ops): New target_ops struct for nindy.
4372 * remote-vx.c: Use write_memory rather than target_write_memory
4373 to get error checking.
4374 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4376 (vx_create_inferior): Use target_terminal_ours...
4378 * signame.c (_initialize_signame): Always initialize, since
4379 we need the table for things other than psignal.
4381 * solib.c (solib_add): Use symbol_file_add, not add_file.
4382 (solib_address): Return boolean result rather than struct
4383 pointer which nobody else knows the type of.
4385 * sparc-tdep.c, valops.c: Use write_memory rather than
4386 target_write_memory, to get error checking.
4388 * stack.c (locals_info, catch_info, args_info,
4389 get_selected_block, frame_command, up_command): Use
4390 target_has_stack, rather than have_inferior_p or
4393 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4395 * symfile.h: New file, defining the interface between the
4396 generic and object-file-specific symbol reading code.
4398 * symtab.c: Move generic symbol-reading interface to symtab.c,
4399 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4400 table to map BFD targets to symbol-reading modules in GDB.
4401 Change index to strchr.
4402 (lookup_struct_elt_type): Use error() rather than hand-made
4403 simulations thereof.
4404 (lookup_partial_symbol): Speedup slightly when length == 0.
4405 (symbol_file_add): New function.
4406 (symbol_file_command): Call it.
4407 (symfile_open, symfile_init): New function.
4408 (add_file_target_command, add_file_addr_command): moved from
4411 * target.c (target_command): use target_kill.
4413 * target.h (target_files_info): Don't declare, never called
4416 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4417 files to determine stack end address.
4419 * valarith.c (value_x_binop, value_x_unop): Change error message
4420 to be more useful. Pass proper argument to value_struct_elt.
4422 * valops.c (value_assign): FIXME comment that long long
4423 bitfields will break here.
4425 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4426 Update `make saber_gdb' to work better.
4428 * TODO: A woman's work is never done.
4430 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4431 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4432 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4433 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4434 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4435 valops.c, valprint.c, exec.c: Lint.
4438 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4440 Continuing Intel 960 port merge of GDB.
4442 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4443 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4444 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4445 Wack over "make depend" so it handles files in subdirectories
4446 vx-share, nindy-share, bfd, and in the current directory.
4448 * blockframe.c (get_prev_frame_info): Remove fatal error
4449 if stack not defined.
4451 * core.c (core_open, core_detach): New functions that handle
4452 the old "core-file" command as "target core" and "detach" instead.
4453 (core_file_command): Call them.
4454 (core_xfer_memory): Use common routine xfer_memory.
4456 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4457 dbxread now uses bfd for everything but symbol reading itself.
4458 BFD internals are used to drag out the relevant file offsets.
4459 (partial_symbol_file_open): Change args all around for BFD.
4461 * symtab.c: Rename "value" to "val" everywhere, so we can
4463 (symbol_file_command): New command, moved from dbxread.c
4464 and coffread.c. It uses BFD to read the file, then vectors
4465 based on its type, to dbx or coff symbol readers.
4466 * symtab.h: Extern a few vars for symbol_file_command.
4468 * target.h: Breakpoint takes a char * save area, not a char **.
4470 * valprint.c (val_print): When unpacking bitfields, offset
4471 the address in gdb of the value, if it is declared with a shorter
4472 type. Remove the last "runtime kludge test" of host byte order.
4474 * utils.c: Remove old my_bfd_read routine.
4476 * stack.c (frame_info): Use target_has_stack. Print program counter
4477 register's actual name rather than "pc", since it's called the
4478 "ip" (instruction pointer) on the i960 (sigh).
4480 * target.c (target_command): Add command for selecting a target
4481 type and calling its open routine. This is used for initiating
4482 communication with a particular target, in a generic way.
4484 * tm-i960.h: Update for modern gdb. Remove semicolons from
4485 various macros. Handle reading struct return convention, and
4486 error-out attempts to return structs with the "return" command.
4487 Be sure gdb doesn't think we know how to call functions in the
4490 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4491 to i960_xxx in lower case.
4492 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4493 not being defined yet.
4495 * remote.c (remote_open): Call start_remote to initialize
4496 wait_for_inferior during open.
4497 (remote_xfer_inferior_memory): Return length written rather
4500 * remote-vx.c (target_command -> vx_open): Use new generic
4502 * remote-eb.c, inftarg.c, exec.c: ditto.
4504 * infrun.c: Fix comments.
4505 (attach_program -> child_open): Use new generic target command.
4506 (wait_for_inferior): Clear saved register values before target_wait,
4507 so target_wait can set some of them if convenient.
4509 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4510 Return success indicator, not void.
4511 (child_xfer_memory): Avoid fetching initial word if we'll
4512 overwrite it anyway.
4514 * infcmd.c (attach_command): Use new generic target open routine.
4515 (_initialize_infcmd): Update doc on attach and detach commands.
4516 (do_registers_info): Merge in a byte-order problem as a FIXME
4519 * findvar.c (find_saved_register): Avoid problem in current frame.
4520 (read_relative_register): Ditto.
4521 (write_register): Convert byte order on the way out.
4523 * exec.c (file_command): Add.
4524 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4525 (xfer_memory): Common function between core_xfer_memory and
4527 (exec_xfer_memory): Use it.
4529 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4531 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4532 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4533 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4535 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4537 Merge Intel 960 port of gdb, continuing...
4539 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4540 symbol_file_command): Pass from_tty arg to hush 'em up.
4542 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4543 Add magic numbers for 960 COFF format.
4545 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4547 Merge Intel 960 port of gdb, from Intel "1.2" release.
4549 CHANGE_LOG entries from their port, which was based on
4552 Thu Sep 6 11:02:22 PDT 1990
4553 Remove temp file if download is interrupted.
4555 Wed Aug 1 09:08:33 PDT 1990
4556 Now uses binary protocol to talk to NINDY.
4557 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
4558 Times out after 5 seconds when trying to talk to NINDY.
4560 Tue May 29 12:54:49 PDT 1990
4561 Added variable baud rate (-b switch).
4562 Source code reorganization.
4564 Thu Apr 26 11:09:55 PDT 1990
4565 More cleanup of batch mode; specifically, execute "-s", "-e", and
4566 "-se" switches as soon as they are encountered on the invocation line.
4568 Fri Apr 20 13:47:15 PDT 1990
4571 Thu Apr 19 09:54:28 PDT 1990
4572 Add 'reset' command.
4574 Wed Apr 18 09:48:07 PDT 1990
4575 After opening remote tty, wait for 1 second to go by without input
4576 from it before trying to talk to NINDY (fixes problems with the
4577 Heurikon HK80/V960E).
4579 Mon Apr 4 16:33:05 PDT 1990
4580 Some output was not being suppressed in 'batch' mode.
4582 Thu Mar 22 15:31:11 PST 1990
4583 Ask user if old symbol table should be deleted when new file is
4586 Allow user to run a program downloaded before gdb960 was brought up.
4588 Correct "exec-file" help message for i80960 context.
4590 Correct bug in calculating user space address: could occasionally
4591 corrupt user program.
4593 Make sure to zero low-order bits in rip's because of bug in 960CA
4594 A-step part: could cause operation faults when "next"ing across
4597 Correct bug that made it impossible to get source line numbers for
4598 code loaded at addresses higher than 0x7fffffff.
4600 Wed Jan 10 12:43:22 PST 1990
4601 Open remote tty for exclusive use.
4603 Fri Jan 5 12:14:42 PST 1990
4604 Correct disassembly (CA manual was right after all):
4605 opcode for sysctl is 0x659
4607 Mon Oct 23 12:03:04 PDT 1989
4608 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4610 Mon Oct 16 14:15:09 PDT 1989
4611 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4613 Mon Oct 2 15:56:31 PDT 1989
4615 Added 960CA disassembly support.
4617 To simplify maintenance:
4618 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4620 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4621 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4622 - made disassembly interface identical to that in gdmp960.
4626 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4628 * target.h: Allow targets to stack. Add target_has_memory,
4629 _registers, etc. Restructure memory access and "info files"
4630 to walk the target stack.
4631 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4632 target.c: Change tables to match target.h.
4633 * inflow.c (child_mourn_inferior): pop child_ops.
4634 (generic_mourn_inferior): Use new has_stack flag.
4635 * infptrace.c (child_xfer_memory): New memory regime.
4636 * inftarg.c (child_files_info): New "info files" regime.
4637 * remote-eb.c: New memory regime, new info files.
4638 * remote-vx.c: New memory regime, new info files. Now use
4639 separate targets for VxWorks attachment to machine, and
4640 actually running a process under VxWorks, since one has
4641 stack & execution & regs and the other doesn't.
4642 * remote.c: New memory regime, new info files.
4643 * sparc-xdep.c (fetch_core-registers): New memory regime.
4644 * target.c: New routines and support for stacked targets,
4645 new memory regime, new info files regime.
4648 Generalize section handling for an arbitrary number of sections,
4649 including use of the new BFD (binary file) library.
4650 * gdbcore.h: Add struct section_table.
4651 * exec.c (build_section_table): Iterate all sections and
4652 record what gdb needs to know about them.
4653 (exec_command): Use it.
4654 (exec_xfer_memory): Use the table.
4655 (exec_files_info): Print the table.
4656 * core.c (core_file_command, core_xfer_memory, core_files_info):
4658 * source.c (find_source_lines): Use bfd_get_mtime.
4659 * dbxread.c: Quick changes to make it compile with new BFD.
4660 * utils.c (error): Avoid using bfd_error in generic routines.
4662 * core.c (core_fetch_registers): Get from the ".regs" section of
4664 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4666 * inferior.h (attach_flag): Export.
4667 * infcmd.c (run_command): use new target_create_inferior.
4668 * infrun.c (child_create_inferior): Don't return result.
4669 * Makefile.dist (VERSION): 3.91.4.
4671 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
4673 * breakpoint.c (bpstat_num): Handle breakpoints which have
4674 since been deleted, such as temporary breakpoints.
4675 infcmd.c (program_info): ditto.
4677 * core.c (core_file_command): Display the frame where the core
4682 * remote-vx.c (target_command): Merge in target command from
4683 targ-vx.c. A few other cleanups.
4685 * TODO, Projects: Lots more stuff to do...
4687 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4689 Massive changes to wall off the remote-debugging interface
4690 behind a function vector. The port to handle VxWorks targets
4691 is also part of this.
4693 All files: Replace references to renamed functions,
4694 remove references to remote_debugging, remove references to
4695 have_include_file, have_core_file in favor of target_has_stack,
4696 target_has_memory, etc.
4698 * Modularize the breakpoint interface.
4699 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4700 a breakpoint instruction.
4701 breakpoint.c: struct breakpoint's shadow_contents now sized as
4703 (insert_breakpoints): Vector to target to install breakpoints.
4704 (remove_breakpoints): Vector to target here too.
4705 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4706 sparc-tdep.c (single_step): Use new breakpoint interface for
4707 the single-step breakpoints.
4708 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4709 New file, contains routines to insert and remove breakpoints by
4710 reading out the old contents and later replacing them. This is
4711 how ptrace breakpoints work, and many remote systems as well.
4713 * tm-vxworks68.h: New config file, overrides a few things for
4714 Wind River's preferences.
4716 * target.h: New file, for transfer vector used to talk to the
4717 inferior (child, attached, core, exec, remote, etc). All accesses
4718 to the thing being debugged should come through these vectors.
4719 target.c: New file, routines to handle transfer vector.
4720 (various files): Add transfer vectors XXX_ops for the various
4721 targets and pseudo-targets (core files, etc) we support.
4723 * breakpoint.c (bpstat_stop_status): Further explorations of
4724 watchpoints and why things don't work all the time.
4725 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4727 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4728 the local gdbinit if it doesn't already have it.
4730 * core.c (core_ops): add and install.
4731 Allow core debugging without exec file.
4733 * dbxread.c (free_and_init_header_files): Merge two fns.
4734 (end_symtab): Free named symbol table when a new version comes in.
4735 (read_dbx_symtab): Relocate all kinds of symbols with base
4736 address. First step toward handling different text, data, bss
4738 (add_file_addr_command): Renamed add_file_command.
4739 (add_file_command): Vector to remote handler.
4740 Add "load" as an alias for "add-file" command.
4742 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4743 non-returning functions.
4745 * exec.c: Add exec_ops, and push it as a target when an exec
4748 * infcmd.c (run_command): Pass executable file name and arg list
4749 separately when starting an inferior. Permit "run" when no exec
4750 file is specified, for VxWorks.
4751 (detach_command): Move to child_detach in inftarg.c.
4753 * inftarg.c: New file. Unix-child-specific routines, and the
4754 child_ops structure.
4756 * inferior.h (registers): Export "registers" as the way for
4757 target dependent register handlers to find gdb's local copy of
4758 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4759 since it is now used by places that want wait_for_inferior to
4760 handle the grunge but want to see every trap from the inferior.
4762 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4763 Eliminate remote_debugging hooks in terminal handling.
4765 * infrun.c: Replace start_inferior with child_create_inferior.
4766 Move all the hair of Unix shells and ptrace idiosyncracies into
4767 child_create_inferior, so remote handlers don't have to deal.
4768 Remove running_in_shell. Rename stop_after_attach to
4769 stop_soon_quietly, and use it in a few other places where we want
4770 to just call wait_for_inferior and get control back on the first
4771 trap. trap_expected now never takes a value > 1.
4772 (init_wait_for_inferior): Initialize static vars when a new
4775 main.c (gdbinit): Add new hook for .gdbinit file name, let
4776 it be overridden by config files as GDBINIT_FILENAME.
4777 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4778 Both of these are used for VxWorks gdb.
4780 mcheck.c: rename include file "gmalloc.c" to avoid problems
4781 with system include file "malloc.c".
4783 param-no-tm.h: New include file, same as param.h but does not
4784 include the default "tm.h" file. This is used in files where
4785 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4787 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4789 remote-vx.c: New file, VxWorks remote debugging support. Uses
4790 RPC routines that are shared with the target system, in directory
4793 remote.c: Vectorize remote interface.
4795 source.c: Globalize source_path, and make an alias "l" for "list"
4796 since we now have the "load" command.
4798 sparc-xdep.c: Use new param-no-tm.h.
4800 symmisc.c (free_named_symtab): Add new function from Wind River.
4801 However, ifdef it out for now while we think about what it should
4804 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4806 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4807 non-Unix-children handle this with their own code in the target
4810 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4811 source and target lists. Add vx-share to default list of include
4812 directories. Add new files to src and target lists: mem-break,
4813 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4814 ${srcdir} versions of munch and createtags are used.
4816 * valops.c (find_function_addr): Split out of call_function.
4817 (call_function_by_hand): Rename call_function; this function
4818 calls functions in the target by laboriously patching the target
4819 word-by-word with the right stack, args, regs, etc.
4822 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
4824 Handle AMD 29000 a bit better.
4826 * remote-eb.c (readchar): Mask received char log to make it readable.
4827 (remote_start): Pass arguments down to executing program.
4828 Make startaddr unsigned.
4829 infrun.c (start_inferior): Accept args, pass them to
4831 infcmd.c (run_command): Pass args down to start_inferior.
4833 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
4834 the target object file format.
4835 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
4837 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
4838 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
4840 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
4842 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
4843 * TODO: We did a few things, we have more to do though.
4845 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
4846 * inflow.c (inferior_died): Clear deferred stores.
4848 * Debug problems with dummy frames and calls to the inferior.
4849 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
4850 * sparc-tdep.c (do_restore_insn): Simplify.
4851 (sparc_frame_find_saved_regs): Simplify and fix what we find.
4852 (sparc_push_dummy_frame): Simplify and fix what we push.
4853 (sparc_pop_frame): Slightly more hair here, deciding whether
4854 we are restoring a saved PC or returning to a return address in %i7.
4855 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
4857 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
4858 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
4859 * obstack.h (chunkfun): ditto.
4860 * defs.h (xmalloc, xrealloc): ditto
4862 * utils.c (quit): Grab the terminal from the child if necessary.
4864 * inflow.c (term_status_command): Rename to term_info, change
4867 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
4868 (is_delayed_branch): Speed up.
4869 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
4870 Still missing some float ops, and needs testing.
4872 * Support for input and output radixes other than base 10
4873 * defs.h (input_radix, output_radix): Declare.
4874 * expread.y (yyparse, parse_number): Handle changes of input
4875 radix, and ambiguous names-or-numbers in radixes >10.
4876 * printcmd.c (print_scalar_formatted): Print formatted hex
4877 numbers in varying column widths.
4878 * valprint.c (val_print): Use output_format to print scalar ints.
4879 (set_input_radix, set_output_radix, set_radix): Create.
4880 (set_output_radix): Set output_format from output_radix.
4881 (_initialize_valprint): add `set radix' but leave the others off.
4883 * main.c (execute_command): Let stupid questions be turned off.
4884 (_initialize_main): Handle "set stupidity", etc.
4886 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
4887 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
4889 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
4891 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
4892 bfd stuff is still screwed up, but with some manual work, it
4895 * breakpoint.c (bpstat_do_actions): Start over if a command
4896 proceeds the inferior, since the inferior will have stopped and
4897 will need to have its new stop-actions taken care of.
4899 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
4900 compiler fits, simplify it.
4902 * gdb.texinfo (directory command): Doc new dir command.
4903 source.c (directory_command): "dir" now puts things on the front
4904 of the path, moves dups up front, and handles multiple names
4905 on the command line, inserting each one in order. It also
4906 blows away cached line and full_filename info.
4908 * stack.c (backtrace_command): Skip "more stack frames follow"
4911 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
4912 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
4913 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
4914 The only odd one was Gould NP1, which had defined vprintf to
4917 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
4918 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
4919 variable, inspect_it.
4920 valprint.c (print_string, val_print): Use the global inspect_it
4921 to indicate whether to print in Epoch style or normal style.
4923 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
4925 * printcmd.c (call_command): add an alias for the "print" command
4926 which runs expressions and doesn't print the result if void.
4927 (print_command_1): implement it.
4929 * command.c: Remove #if 0'd code. Initialize all the fields
4930 in add_cmd (). Rename do_nothing_command to
4931 not_just_help_class_command, and make it externally visible.
4932 command.h: add user_commands to struct.
4933 * main.c (define_command): Don't overload c->function with a char
4934 string as well as a function pointer.
4936 * eval.c (evaluate_subexp): Reinstall tiemann changes to
4937 calling convention of value_struct_elt () that got dropped in
4940 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
4941 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
4943 * tm-sparc.h (POP_FRAME): replace some constants with defines.
4945 * sparc-xdep.c (store_inferior_registers): defer stores to regs
4946 until a good time (e.g. when we are about to run the child),
4947 saving ptrace calls.
4948 * infrun.c (proceed): handle DO_DEFERRED_STORES.
4949 * tm-sparc.h: define DO_DEFERRED_STORES.
4951 * sparc-xdep.c (store_inferior_registers): when storing float
4952 registers, don't store stack regs too. When storing the SP,
4953 however, DO store the stack regs too. This fixes a bug in which
4954 the dummy frame is not recognized when a call_function finishes,
4955 because its frame pointer (in the stack regs) was never
4957 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
4958 even though we don't know how to read them from an inferior.
4959 valops.c (call_function): Comment about storing SP.
4961 * infrun.c (save_inferior_status): Save away the original bpstat
4962 chain so it can be restored later. Install the copied version for
4963 use by whoever saved the status. It will be blow away by
4964 restore_inferior_status, and the original chain restored. This is
4965 important for people who have pointers into the original.
4967 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
4968 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
4969 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
4972 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
4974 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
4975 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
4976 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
4978 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
4980 * Merge Mike Tiemann's multiple inheritance changes from Sun.
4981 Store the baseclasses in a type struct starting from array element
4982 0 rather than from the unusual array element 1.
4984 dbxread.c: the above.
4985 (virtual_context): Add
4986 Read new debug information about which virtual function table
4987 a virtual function is from, and store it in fn_field.fcontext.
4989 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
4990 TYPE_FN_FIELD_STATIC_P.
4992 symtab.c: the above.
4993 valops.c: the above. Handle pointer casts of object *'s.
4994 (search_struct_method): Add.
4995 (value_struct_elt): First arg is now a pointer to a value, and is
4998 valprint.c: the above.
4999 values.c (value_virtual_fn_field): Add type arg. Handle
5000 offsetting to the proper object when calling virtual fns.
5002 (baseclass_addr): Add valuep arg.
5004 * README: Document the current state of BFD config (missing).
5005 * TODO, ChangeLog, Makefile.dist: Roll version.
5006 * WHATS.NEW: Add summary of changes since 3.5.
5008 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
5010 * dbxread.c (read_struct_type): Clear bit vectors whenever
5012 symtab.c (B_CLRALL): define.
5014 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5015 using == rather than =. Huh... This fixes the dreaded problem
5016 wherein builtin_type_int becomes TYPE_CODE_FLT.
5018 * core.c (info_files): Show the inferior pid.
5020 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5021 already knows how to look in the source directory.
5023 * Remove psymtab hair from many places. Remove duplicated code
5024 for searching symbol tables. Hide psymtabs from most places.
5025 Make it fast to get from a psymtab to its symtab.
5027 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5028 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5029 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5030 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5031 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5032 new symtab completely. New psymtabs get symtab pointer
5033 initialized to zero. Remove MI warning printf.
5034 symtab.h: Comments. Add psymtab to symtab pointer.
5035 (PSYMTAB_TO_SYMTAB): New macro.
5036 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5037 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5039 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5041 (print_frame_info): Avoid special-casing symbols that have not yet
5044 * source.c (open_source_file): Quick path if we have already
5045 located the source file by its full name.
5047 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5048 find_pc_psymtab. When a name is found in the misc function
5049 vector, search the symbol table for its mangled name, not the
5050 name that the user typed.
5052 * bfd.h: Fix missing comment terminators, make #endifs match.
5054 * valarith.c (value_less): Handle unsigned int comparisons.
5055 Add FIXME about pointer compares, which assume host and target
5056 pointers are the same.
5058 * command.c (do_nothing_command): lint
5059 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5060 fix comments on debug symbol format for visibility. Actually set
5061 visibility of symbols.
5062 main.c (echo_command): lint; use <readline/history.h>.
5063 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5064 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5065 pointing past end of allocated memory; saber complains.
5066 obstack.h: Declare the external functions that we use.
5067 valarith.h: use <string.h>
5068 solib.c (solib_add): lint.
5070 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5072 * main.c (initialize_main): Default info_verbose to off, now that
5073 symbol reading is fast.
5074 (quit_command): Avoid clobbering exec_bfd while quitting.
5076 * Initial BFD (binary file diddling library) merger:
5077 coffread.c: Change AOUTHDR to struct exe_hdr.
5079 core.c: initialize initialized data at compile time.
5080 (core_file_command): Move from coredep.c, convert to bfd.
5081 (xfer_core_file): Convert to bfd.
5082 exec.c (exec_file_command): use bfd routines.
5084 mips-tdep.c: Remove exec_file_command and friends.
5087 * coredep.c: (fetch_core_registers) Convert core_file_command to
5088 fetch_core_registers.
5089 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5091 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5092 (my_bfd_read): More bogosity, which I don't think we call.
5093 (program_name): Remove this atrocity asap!
5095 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5098 values.c: allocate_repeat_value was not clearing the
5099 optimized_out field.
5100 (value_static_field): minor stylistic fix (wrong macro was used).
5101 valops.c (value_struct_elt_for_address): didn't work for C++
5104 * signame.c (_initialize_signame): Initialize signal names once.
5106 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5107 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5108 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5110 * remote-eb.c: Support user-settable baud rates on the serial port.
5112 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5114 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5116 * tconfig/sun3os4: Remove warning about native assembler,
5117 since it also occurs in the xconfig file.
5119 * findvar.c (registers): Allocate some slop after `registers'
5120 to prevent stray accesses from trashing the next variable.
5122 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5123 on the sun-3, by changing the #ifdef from `sun3' (which is not
5124 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5125 vars, which happened to follow `registers' in the executable.
5127 * readline/history.c (history_search): Heed gcc-2's advice
5128 and parenthesize && inside ||).
5130 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5131 tm-29k.c: Insert FSF copyright headers.
5133 * remote-eb.c: Better comments.
5135 * Makefile.dist: Update to 3.91.6.
5136 * TODO: note PREPARE_TO_STORE problem.
5138 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5140 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5142 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5144 * infrun.c (wait_for_inferior, at end): Don't set up
5145 prev_* if the inferior no longer exists.
5147 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5148 CANNOT_EXECUTE_STACK.
5149 valops.c (call_function): Use it.
5151 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5153 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5154 infrun.c (wait_for_inferior, 2 places): Use it.
5156 * values.c (value_being_returned): Only use
5157 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5159 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5160 right thing for remote-eb.c.
5162 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5163 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5165 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5166 (FRAME_FIND_SAVED_REGS).
5168 * findvar.c ({fetch,store}_registers): Check for
5169 REMOTE_{FETCH_STORE}_REGISTER macro.
5171 * findvar.c (get_saved_register): Add argument lval and
5172 change meaning of argument addr.
5173 findvar.c: Change calls to get_saved_register to reflect
5174 new calling convention.
5175 valops.c (value_assign): Use get_saved_register instead of
5176 find_saved_register.
5178 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5180 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5181 an (uninitialized) pointer to one. Use "&" when passing it
5184 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5186 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5189 * coffread.c (symbol_file_command): Put semicolon after
5191 Put safe_to_init_tdesc_context in #if defined (TDESC).
5192 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5193 coffread.c: #include <sys/stat.h>.
5194 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5195 Add missing ')' in check for "lc%" and friends. Remove
5197 Declare read_one_sym() at top of file.
5198 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5199 MC68WRMAGIC can have the same value without causing a duplicate
5202 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5204 * Allow a Makefile to be built without building the
5205 tm and xm file links that screw up builds in subdirectories.
5206 This is done with `config.gdb none', then you can do things
5207 like `make gdb.tar.Z'.
5208 * tconfig/none: Config file for no target system
5209 * xconfig/none: Config file for no host system
5210 * config.gdb: If no TM or XM files are called out by the
5211 host or target file, don't make links for them.
5213 * cplus-dem.c: Add documentation.
5215 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5216 simple error, so the user's gdb doesn't crash due to some object
5217 file problem (e.g. somebody is rebuilding the file out from under
5220 * printcmd.c (print_address_symbolic): demangle the symbol.
5222 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5223 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5224 (alldeps.mak): sort and uniq all results from this; duplicates
5225 hose gdb.tar.Z link building. Remove RCS files from
5226 tconfig and xconfig. Add config files for sun386. Add
5227 a few odd files to OTHERS and HFILES.
5229 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5231 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5232 Roll version number to 3.91.5. Make lint work in bindir.
5234 * README: Document cross-debugging and new file structure.
5236 * blockframe.c: Lint. Include "value.h" to declare read_register.
5237 (find_pc_partial_function): remove duplicate line.
5239 * command.h: Lint. Declare error_no_arg and dont_repeat.
5241 * tm-news.h: Remove inadvertently duplicated stuff.
5243 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5244 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5246 * config.gdb: Allow `config.gdb host target' form. Clean
5247 up previous change that printed bogus messages when you just said
5250 * core.c: #include "command.h" for lint.
5253 * main.c: Remove some casts of enums. Lint.
5260 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5262 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5263 read it from memory. This will allow us to save ptrace calls
5264 eventually. Changed caller single_step too.
5266 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5267 that we aren't going to use, saving many ptrace calls, especially
5268 when watchpointing or single stepping. Use some #define's for
5270 (store_inferior_registers): Ditto.
5271 (core_file_command): Use some #define's for constants.
5273 * tm-sparc.h: Add #define's for some register numbers, so we
5274 can eliminate the use of random constants in sparc-xdep.c.
5276 * stack.c (frame_command, print_frame_info, up_command,
5277 down_command) Remove frame_changed, since it
5278 causes a bug and doesn't seem to do anything useful. In some
5279 places it was used as a flag, in others as a stack level (?).
5281 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5282 default is to use the portable (vprintf) version rather than the
5284 * xm-news.h (MISSING_VPRINTF): Add.
5286 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5288 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5290 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5291 about linking debugged programs -Bstatic in the sun?os4 config
5292 files in tconfig and xconfig subdirectories.
5294 * main.c (main): Remove unreached exit(0) now that we exit
5297 * Create TODO file for online bug list. There are too many
5298 "little" bugs to keep track of on paper.
5300 * Change Projects file to refer to bug-gdb@cygnus.com
5301 rather than kingdon@ai.
5303 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5305 * Makefile.dist (VERSION): 3.91.4 now.
5307 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5308 (condense_misc_bunches): Add sanity check that misc_count is
5309 the same as the number of symbols in the bunch.
5311 * coffread.c: rename init_misc_bunches. Pass an argument
5312 to condense_misc_bunches (a zero).
5314 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5315 every time we are called; don't rely on our caller to do it.
5316 (add_file): Remove call to init_misc_bunches.
5318 * mipsread.c: Only warn, don't error, if unknown symbol types.
5319 This keeps an old gdb from falling on its face if it sees newly
5320 extended symbol info. Rename init_misc_bunches.
5322 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5324 * Merge in changes from Per Bothner for DECstations and other
5325 MIPS stuff. The rest is Bothner speaking:
5327 The next message is a merger of Alessando Forin's mips port with
5328 mine. I've tried to use my good if biased judgment to get
5329 the best of both. It *does* need testing.
5331 Some of the changes are general, *not* mips-specific.
5334 Didn't believe in little-endian bit order.
5335 There are still inconsistencies about whether flags
5336 like BITS_BIG_ENDIAN are integer (#if ...) or
5337 boolean (#ifdef ...). I tried to paper over them.
5339 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5340 Moved some misc_function code that was common to
5341 {dbx,coff,mips}read.c to symtab.c.
5342 In the process, I think I cleaned things up a bit.
5343 At the same time, moved obsavestring and obconcat to symtab.c.
5346 Removed obsolete condense_addl_misc_bunches (use
5347 condense_misc_bunches(1) instead).
5350 Needed to include <sys/dir>, at least on DECstations.
5352 valops.c, mips-tdep.c, tm-mips.h:
5353 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5354 conventions (when STACK_ALIGN is insufficient).
5355 Needed on mips, where doubles need 8-byte alignment,
5356 but ints only need 4.
5359 Removed cruft that was not being used.
5360 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5363 Print $ before register-names (I think that makes things a little
5365 Never print two instructions, even if one delays.
5366 Removed hex-disassemble set_cmd. (This is not mips-specific,
5367 so I think the argument is whether it is generally worthwhile or not.
5368 I'm inclined to think not, given how easy it is to
5369 convert between radixes in gdb.)
5372 This is basically Alessando's code.
5373 It doesn't use obstacks; I changed it to use obstacks
5374 in a few minor places where using malloc causes a
5375 memory leak. (Probably, more places could/should be changed.)
5376 I added record_misc_function where it was missing.
5377 In symbol_file_command and add_file_command, I tried
5378 to make the code consistent with more recent versions.
5379 Minor sylistic changes in parse_procedure.
5380 Make a .gdbinfo. psuedo-symbol point back to the real
5381 procedure symbol (using the isym field).
5384 This is basically from my port, but with a lot of details
5385 and a number of routines merged in from Alessando's version.
5386 I basically used my code "raw" backtrace (use heuristics
5387 from the actual code, rather than symbol table info) - though
5388 the idea is Alessandro's. I feel my code is a little cleaner
5389 here, particularly in being a little more flexible, such as being
5390 able to handle gcc-produced code (which it now can).
5391 It also doesn't do frame caching (which is not useful
5392 more recent gdb versions).
5393 I also used my code for push_/pop_dummy, more or less.
5394 I tried to incorporate AF's code for testing sigtramp
5395 while backtracing; I probably got it wrong.
5396 Added mips_print_register, which tries to scrunch as much
5397 information as possible on a screen...
5398 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5399 under mips-pinsn.c), I don't see anything mips-specific here,
5400 and I don't see it being all that useful anyway.
5403 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5404 Use more register names (rather than hard-cases numbers).
5406 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5408 * Hack up 3.90.11 changes:
5410 * Makefile.dist (depend): parameterize $(GCC).
5411 Add solib.c and solib.o.
5412 (readline): Fix vpath for both absolute or relative SRCDIR.
5414 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5415 Also, let the part I didn't understand at least compile so
5416 I can test the rest. FIXME.
5418 * dbxread.c: Fix thinko using strcmp.
5419 (init_psymbol_list): declare static.
5420 (partial_symbol_file_open): Comment cleanups better, avoid
5421 cleaning up the string table since the caller will do that.
5422 Move the stat for mod time into symbol_file_command, temporarily.
5423 (There should be a mod time for each symbol file, eventually,
5424 to control its rereading. FIXME.)
5426 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5427 SunOS, which gives error for shared libs otherwise. (From
5428 Schaefer, probably FIXME needs work for portability.)
5430 * solib.c: Move #include "param.h" to work.
5431 Lowercase all the Uppercase Letters In the Messages.
5432 (find_solib): Clean up inferior_so_name for debug printouts.
5433 Allow no argument, to mean all shared libraries.
5435 * symmisc.c: include param.h to get CLEAR_SOLIB.
5437 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5439 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5440 to 3.90.11. ChangeLog entries below are from this.
5442 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)

5448 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5452 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5454 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5456 * sparc-opcode.h Added single-operand version of rett.
5458 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5460 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5461 Put parens around gcc_p in expansion.
5463 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5465 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5467 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5469 * Changes for Sun shared libraries:
5470 blockframe.c (find_pc_partial_function): If a non-text symbol
5471 is found, set *address = pc - FUNCTION_START_OFFSET.
5472 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5473 Disable breakpoints instead of giving an error.
5474 source.c (select_source_symtab): Initialize cs_pst.
5475 symmisc.c: Call CLEAR_SOLIB if defined.
5476 symtab.h: Make text{low,high} CORE_ADDR not int.
5477 (psymtab): New field addr.
5479 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5480 (record_misc_function): Give correct type for N_DATA symbols.
5481 (condense_misc_bunches): do "misc_function_count = j" regardless
5483 Take code which is shared between symbol_file_command and
5484 add_file_command and put it into partial_symbol_file_{open,read}.
5485 Split add_file_command into add_file_command and add_file.
5486 Make psymtab_to_symtab read in the string table if the file
5488 Two new parameters to read_dbx_symtab and start_psymtab.
5489 tm-sunos.h: New file.
5491 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5493 * infcmd.c: Change cont_command to continue_command and "cont"
5496 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5498 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5500 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5502 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5503 size 1,2,4,8 rather than size < 8.
5505 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5506 as necessary, not just once.
5508 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5510 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5512 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5514 * tm-news.h: Add CALL_DUMMY_*.
5516 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5518 * config.gdb: In list_host, list_target, use ${i}, not $i.
5520 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5522 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5524 * sparc-opcode.h: Change all store floating-point state register
5525 instructions to have the right match & lose fields.
5527 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5529 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5531 config.gdb: If srcdir != ., create readline directory and
5532 copy a makefile into it.
5534 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5535 consistency with POSIX.
5537 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5538 when we exit its exp_valid_block.
5540 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5542 * Makefile.dist: Bump version to 3.91.3.
5544 * Clean up handling of breakpoint commands (somewhat).
5545 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5547 inferior.h: Add breakpoint_proceeded to inferior status struct
5548 and globals; save it and restore it.
5549 (clear_breakpoint_commands): Cleanup, remove old #define.
5551 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5552 (save_inferior_status, restore_inferior_status): handle it also.
5553 (proceed): Remove earlier code that set breakpoint_proceeded.
5554 It is now set only in clear_proceed_status.
5555 (clear_proceed_status): Cleanup, use bpstat_clear rather
5556 than clear_breakpoint_commands. No callers need the stop_bpstat
5557 between clear_proceed_status and proceed.
5559 infcmd.c: Add breakpoint_proceeded definition and comment.
5560 (cont_command, jump_command, signal_command): Move call to
5561 clear_proceed_status right next to call to proceed.
5563 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5564 caller's argument while running down the chain of breakpoints.
5565 Use new variable "breakpoint_proceeded" to determine when
5566 a command that it executes moves the inferior past the
5568 (bpstat_clear): Handle NULL argument.
5569 (bpstat_clear_actions): Avoid useless call to
5570 breakpoint_auto_delete.
5571 (delete_breakpoint): Clean up bpstat's that are pointing to
5572 the deleted breakpoint from the stop_bpstat chain.
5573 (breakpoint_auto_delete): Simplify.
5575 * Clean up handling of EOF, error on stdin, etc. This was
5576 prompted by a network problem that caused gdb to go into an
5577 infinite loop filling up its malloc'd memory.
5579 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5580 not clear_breakpoints_commands, which is now gone.
5581 (main): If command_loop returns (e.g. from EOF on stdin), do
5582 a quit_command (looping back to command_loop if quit_command
5583 doesn't really quit).
5584 (command_loop): check result from command_line_input and
5585 exit if it returns NULL, rather than passing the NULL to
5587 (gdb_readline): Free malloc'd result space before returning
5590 * utils.c (query): Handle C-d to mean "yes", just as if the
5591 input was not a terminal. Also avoid infinite loop if EOF
5592 occurs in mid-input-line before newline. This allows
5593 query to be used at EOF on stdin with reasonable results.
5595 * infrun.c (proceed): Set breakpoint_proceeded.
5597 * values.c (value_as_long): Avoid infinite recursion for enums.
5598 (_initialize_values): Fix typo in help msg (kingdon).
5600 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5601 RL_LIB for linking. This allows -lreadline for linking
5602 and nothing for dependencies, once readline is a real library.
5604 * config.gdb: Jim Kingdon: give useful error message if the
5605 host or target type is not recognized.
5607 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5608 it just defines it. Dumb, but deal with it.
5610 * Jim Kingdon suggests:
5611 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5613 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5615 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5617 * Clean up Bothner's changes.
5619 * blockframe.c (clear_pc_function_cache): New function.
5620 * blockframe.c: remake cache_pc_function_* static.
5621 * dbxread.c (symbol_file_command): remove references to
5622 cache_pc_function_* variables.
5623 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5624 * printcmd.c: Avoid kludging a global variable (addressprint)
5625 to avoid printing the address of a string twice. Instead,
5626 pass the format letter 's' down low enough that it can be seen
5627 to avoid this problem.
5628 (print_formatted): Pass format arg to value_print.
5629 (restore_addressprint): Remove function.
5630 (do_examine): Avoid hacking addressprint, cleanups and such.
5631 (print_frame_args): Add a comment to a Bothner change.
5632 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5633 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5634 to wipe out the values cached in blockframe.c.
5635 * symtab.c (find_method): Add comment saying how big you must
5636 allocate to be "big enough". Per being terse again.
5637 * valprint.c (val_print): Handle format letter "s" to print
5638 strings without addresses. Add comment to vtbl printing code
5639 which casts with wild abandon. Rearrange reference-printing
5641 @0xaddr: value (print w/addressprint)
5642 value (print w/~addressprint)
5643 @0xaddr (parameter lists w/addressprint)
5644 or nothing (parameter lists w/o addressprint)
5646 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5648 * Merge more changes from Per Bothner:
5650 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5651 annoying) that I tried to improve it. Here are my suggestions.
5653 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5656 Do automatic de-reference when taking the address of a reference.
5658 Don't deref_ref when printing parameter lists.
5660 More attempts at treating refernences properly.
5662 In val_print, if deref_ref==0, don't print dangling " = ".
5664 Add COERCE_REF macro, which de-references an REF.
5666 * Merge changes from Per Bothner:
5668 * Fixed (Sony news)-specific configuration problems.
5669 * Fixed other problems with using vanilla pcc and libc (enum problems;
5670 assumption that vsprintf exists).
5671 * Some major speed-ups (finc_pc_partial_function now caches a match;
5672 parsing avoids duplicate symbol_lookup calls).
5673 * Changed handling of baseclasses (no longer use baseclasses field
5674 of struct type, use the first n_baseclasses fields instead).
5675 * Various minor changes/fixes, most C++-related.
5678 Cache the most previous match from find_pc_partial_function.
5679 (Save both low and high ends of matching function's pc range.)
5680 This speeds up the loop of infrun.c:wait_for_inferior quite
5681 a bit, and makes step/next commands much zippier.
5683 Added an enum->int cast (otherwise, some compilers barf).
5685 No longer set baseclass offset to 0, since multiple
5686 inheritance now mostly works.
5687 Added a number of casts, to shut up compiler warnings
5688 (after stabs where made enums, not ints).
5689 When discarding a symbol table (in symbol_file_command),
5690 must clear the cache introduced in blockframe.c.
5691 Don't convert $vtbl_ptr_type to vtbl any more.
5692 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5693 Mask off sign bit emitted by g++ for virtual table offset.
5694 Set voffset to -1 (not 1) for static member functions.
5696 Changed parsing/lexing of names to avoid doing symbol lookup twice
5697 (once when lexing to determine symbol class, once for real).
5698 Now only call symbol_lookup once. Fields of 'this' win especially big.
5700 Subpress printing addr twice in the case of 'x/s addr'.
5702 lookup_basetype_type is no longer used.
5703 Add find_methods as recursive helper function to decode_line_1.
5704 This allows multiple inheritance to work.
5705 Also, once one or more matches has been found, do not look in
5706 base-classes. (Baseclass methods would be overridden, anyway.)
5708 Removed baseclasses array in struct type.
5709 Instead of using baseclasses[i], use fields[i-1].
5710 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5711 Changed sign convention of voffset (previous was inconsistent).
5713 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5715 Used to assume existence of vsprintf. Re-written to not need it
5716 if HAVE_VPRINTF is undefined.
5718 typecmp was too pessimistic. Made it less so.
5720 Don't print space after address.
5721 If vtable points to a misc symbol (with 0 offset), print it,
5722 since that indicates the actual class of the object.
5723 Changed ype_print_derivation_info to use new inheritance
5724 scheme (without baseclasses vector).
5726 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5727 Also, changes needed because TYPE_BASECLASSES were removed.
5729 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5731 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5734 If there is no path set, and the symbols don't indicate what directory
5735 a file was compiled in, look in the current directory. But either
5736 a path or a known compilation directory will prevent this.
5739 Three independent bug fixes:
5740 * Remove the #if 0 block that breaks some stuff.
5741 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5742 adapt gdb to either SunOS 4.0.* or 4.1.
5743 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5746 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5749 (type_print) Demangle the name being printed.
5750 (type_print_base) Handle botched demangling without coredump (tiemann).
5753 (check_stub_method): Document routine.
5754 (tiemann) fix bug for no-arg functions
5755 Avoid clobbering beyond end of malloc'd storage.
5756 Terminate the argument list properly.
5758 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5760 * Changes merged by John Gilmore:
5763 In breakpoint_1, use new print_address_symbolic instead
5764 of find_pc_partial_function. (This forces use of assembler-level
5765 addresses, and avoids misleading non-mangled source-level names.)
5767 Generalize ansi argument such that -1 means skip arglist totally.
5768 Removed global variable print_ansi_qualifiers (which made
5769 code non-reentrant), in favor of extra explicit arguments
5770 to internal routines.
5772 Add new helper function print_address_symbolic.
5773 Use find_pc_misc_function instead of find_pc_partial_function
5774 (since we want assembler-level symbols here).
5776 Print unknown function as just "f (...)", not "f (...) (...)".
5777 Use new fputs_demangled explicitly.
5779 Fixed a typing violation (problem: value.h cannot be imported
5780 without renaming many variable in this file).
5781 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5782 decode_line_1: Moved forward some never-reached code.
5783 Made decode_line_2 skip function prologues correctly.
5785 fputs_filtered should not demangle by default.
5786 Add new fputs_demangled to demangle on demand..
5788 Change value_struct_elt to use value_primitive_field (using recursive
5789 utility function search_struct_field). This allows foo.bar to work
5790 for multiple inheritance (so far only for data fields).
5791 Change check_field in the same way (recursive helper function
5792 to support multiple inheritance).
5793 (Note: there are more of these problems that I haven't fixed.
5794 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5795 value_of_this: 'this' symbol name is now just "this", note "$this".
5797 Don't print static members.
5798 Avoid printing "members of <type>" if there are none.
5799 Simplified type_print_derivation_info by merging duplicate code.
5800 Remove useless blank lines in type_print_base (ptype command).
5802 Added declaration of new routine value_primitive_field.
5804 Added value_primitive_field which is generalized version of
5805 value_field that can handle multiple inheritance (non-zero offsets etc).
5806 Re-implemented value_field to call value_primitive_field.
5808 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
5810 * infcmd.c -- insert else to avoid 'delete env' coredump when you
5811 delete the whole environment. Karl Berry reported the bug.
5812 * source.c - fix openp to avoid //'s in filenames, which
5813 trigger an Emacs bug causing it to not be able to find files
5814 when running gdb in a window.
5815 * dbxread.c - zap the #if 0 that botches the add-file code.
5816 It seems to work a lot better without all the code commented out.
5818 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
5820 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
5823 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
5825 * Makefile - added a ${CFLAGS} to a couple of entries,
5826 added remote-sa.sparc.c
5827 * added remote.sa-sparc.c, a modification of remote.c
5828 which conducts a dialog directly with the SparcStation prom.
5829 * breakpoint.c, infrun.c, sparcdep.c added
5830 remote_insert_breakpoint(), and remote_remove_breakpoint()
5831 to breakpoint.c instead of directly writing breakpoint instructions.
5832 * sparcdep.c on remote_debugging,there is no need
5833 to remove signle step breakpoint instructions.
5834 * main.c added "-epoch" flag and "int epoch_interface" to main.c
5836 * printcmd.c - epoch interface sends lisp expressions to open up
5837 epoch windows on inspection.
5838 * valprint.c - added arrayprint, and addressprint and made adding
5839 format controls easier
5840 * wait.h added a couple of undef's because we were getting
5841 complaints about WSTOPSIG and WTERMSIG begin redefined.
5844 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
5846 * symtab.c (decode_line_1): Add support for handling method stubs
5847 in the type information.
5849 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
5851 * values.c (baseclass_addr): Run loop from INDEX+1 to
5852 N_BASECLASSES; otherwise, we can still get into a loop.
5853 @@ This should be restructured to use a cleaner search strategy.
5855 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
5857 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
5858 abbreviation "Tt" for tags which have the same name as their
5861 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
5863 * symtab.c (list_symbols): add ability to set breakpoints on all
5864 the functions which match a particular regular expression.
5866 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
5868 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
5869 should print ANSI qualifiers (such as `const' and `volatile').
5870 All callers changed to call with ANSI == 1, except from
5871 `check_method_stub', which uses old-style syntax.
5873 * symseg.h (struct fn_field): Remove unneccessary `args' field.
5874 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
5876 * values.c (check_stub_method): New function.
5878 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
5880 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
5881 * valprint (type_print_base): Ditto.
5883 * symtab.c (gdb_mangle_typename): New function.
5885 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
5887 * breakpoint.c (catch_command): New function. Provides a
5888 mechanism to set breakpoints based on catch clauses.
5889 (disable_catch): Similar, but disables breakpoints on catch
5891 (delete_catch): Similar, but deleted breakpoints on catch clauses.
5893 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
5895 * blockframe.c (blockvector_for_pc): New function.
5896 * blockframe.c (block_for_pc): Changed to call
5897 `blockvector_for_pc' and get the block itself.
5899 * stack.c (catch_info): New function. Prints info about
5900 exceptions which can be caught in the current frame.
5901 * stack.c (print_frame_label_vars): New function. Similar to
5902 `print_frame_local_vars'.
5903 * stack.c (print_block_frame_labels): Prints out labels that are
5904 defined in this frame. These labels are exceptions that can be
5907 * dbxread.c: Updated to handle N_CATCH symtab types.
5909 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
5911 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
5912 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
5913 when printing the type.
5915 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
5917 * valprint.c (val_print): Use `baseclass_addr' to access the
5918 baseclasses pointed to via the derived class object at VALADDR.
5920 * values.c (baseclass_addr): New function. Casts derived pointers
5921 to baseclass pointers taking virtual baseclasses and multiple
5922 inheritance into account.
5924 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5928 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5930 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
5931 exp_valid_block field correctly.
5933 * infrun.c (wait_for_inferior): When checking "don't even think
5934 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
5935 also check step_resume_breakpoint.
5936 Insert breakpoints and continue (not step) if
5937 step_resume_break_address != NULL, even if another_trap.
5938 If trap_expected and we enter sigtramp, then set up a
5940 If trap_expected is set when we hit the step_resume_break,
5942 When calling resume and trap_expected says tell resume to step
5943 (2 places), also check step_resume_break_address.
5945 * infrun.c (wait_for_inferior): Don't set
5946 prev_{pc,sp,func_{start,name}} before calling wait ().
5947 Do set them after exiting loop.
5948 Move their declarations outside functions.
5949 (start_inferior): Initialize them.
5951 Thu May 3 00:15:11 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5953 * infrun.c (wait_for_inferior, after check for trap_expected > 1):
5954 Restore old code which distinguishes between trap_expected and
