3 Various fixes to improve g++ debugging.
4 * symtab.h: Add is_const and is_volatile flags for each method.
5 These are bit fields - take their space from voffset,
6 which shrinks to 30 bits. Since voffset is now a bitfield,
7 make it unsigned for portability. This changes its interpretation
8 slightly: Static methods now have voffset 1 instead of -1,
9 and virtual offsets start at 2, not 1.
10 * symtab.c: Renamed gdb_mangle_typename to gdb_mangle_name,
11 since it now returns an entire magled method name, not just
12 the type part. This avoids some duplication.
13 It also allows us to correctly mangle const and volatile
14 methods (using the new is_const and is_volatile bit fields
16 * valprint.c (type_print_base), values.c (check_stub_method):
17 Simplify by using new gdb_mangle_name.
18 * values.c (value_headof): Fix to correctly handle single
19 inheritance (actually two fixes, either of which suffices).
20 * dbxread.c (read_struct_type): Handle const and volatile
22 * dbxread.c (read_struct_type): Yet one more place where
23 we must handle '\\' continuations.
24 * valprint.c (vtbl_ptr_name): Add final '\0'.
26 Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com)
28 * tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of
29 short return values for sparc and 68k. Patch from Paul Eggert.
31 * coffread.c, coredep.c, i386-xdep.c: install patches for
32 SysV/386 3.2 from Mauro DePalma.
34 Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
36 * core.c (core_file_info), exec.c (exec_file_info): Print file
37 type. Use printf_filtered.
39 * valops.c (value_fetch_lazy): Avoid 0-length fetches.
41 Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
43 * dwarfread.c: Add casts to remove compiler warnings.
45 * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
46 tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
47 tm-sun3.h: Remove locally duplicated code for calling functions
48 in the inferior. The only differences were in the specific trap
49 vectors used and whether or not an fpu was present. These are
50 now handled by appropriate definitions of BPT_VECTOR and
51 HAVE_68881 respectively. Other minor obvious cleanups.
53 * valops.c: Correct a minor misspelling.
55 * utils.c: Remove local BSD/USG hacks that are now in libiberty.
57 * dwarfread.c: Remove prototype for dwarfwarn. Does not work
60 Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
62 * stack.c (frame_command): Always print. Use new
63 frame_select_command to select a frame without printing.
65 * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
67 Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
69 * dwarfread.c: New file for DWARF debugging format support.
71 * elfread.c: New file for ELF object file format support.
73 * procfs.c: New file for SVR4 /proc (process file system) support.
75 * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
78 * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
80 * xm-m68k.h: New file for host machines with m68k cpu.
82 * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
83 Add elfread.o and dwarfread.o to OBS.
85 * symfile.h: Add "elf" to list of supported formats in comment.
87 * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
88 types to gdb, builtin_type_long_double, builtin_type_complex, and
89 builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
90 TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
91 TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
92 TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
93 types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
95 * infrun.c: When using SVR4 /proc interface instead of ptrace(),
96 call proc_set_exec_trap() to setup child to stop at first instruction.
98 * inftarg.c: When using SVR4 /proc interface, call proc_wait()
101 * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
102 supply_fpregset(), and fill_fpregset(), which are machine
103 dependent support routines for SVR4 /proc interface.
105 * utils.c: Add warning_setup() and warning(). Warning() behaves
106 the same as error() except that it returns normally rather than
107 jumping back to command level. Modules that don't want to call
108 warning() for some reason, but want to produce their own warnings,
109 can call warning_setup() to ensure compatibility with the way
110 warning() and error() deal with the terminal.
112 * symtab.c: Make internal errors produce more useful messages.
114 * tm-68k.h: Move code that is duplicated in almost every single
115 m68k based machine's configuration files to this common file.
116 Duplications in the configuration files still need to be removed
119 * infrun.c (child_create_inferior): System V versions must call
120 setpgrp() with no arguments, to comply with prototyping typically
123 * munch: Add support for SVR4 style nm output.
125 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
126 file specific fields from the partial symbol table structure and
127 replace them with a pointer to private data for each different
128 flavor of object file reader to initialize appropriately.
130 Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
132 * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
135 * mipsread.c (fixup_undef_type): New function. If a struct /
136 union / enum is defined in a header file but nowhere else used,
137 (by typedefing, pointer referencing or declaration) the mipsread code
138 builds the complete tree for the structure but leaves its code as
139 TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
140 Guess its type based on the details of the members.
142 Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
144 * infrun.c (wait_for_inferior): Check return value from
147 Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
149 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
150 by my last edit to this routine.
152 Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
154 * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
155 FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
156 the values before putting them into the dummy code. (From Peter
159 Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
161 * configure.in: added ebmon target.
163 Wed Oct 16 22:49:58 1991 John Gilmore (gnu at cygnus.com)
167 * Makefile.in: Roll VERSION to 4.2.
168 * README, TODO, WHATS.NEW: Update.
170 * core.c (core_open): Improve error message for bad file.
171 Pass .reg virtual memory address to fetch_core_registers to help
172 it find the registers in the core-file header.
173 * coredep.c (fetch_core_registers): Take new argument, use it,
174 and pass it to register_addr to locate the block of registers.
175 * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
177 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
178 Sequent N_FN_SEQ like everybody else's N_FN.
180 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
181 * tm-i386v.h: #endif guck.
182 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
183 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
184 * xconfig/tahoe: Add REGEX, which seems to be missing.
186 * coredep.c: Add <sys/types.h> for SCOnix.
187 * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file.
188 * printcmd.c (print_formatted): Flush output before disassembly.
190 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
192 * doc/refcard.tex (sec "Working Files"): consistent metavars and
193 other improvements, due to comments by François Pinard
194 (pinard@iro.umontreal.ca)
196 * doc/gdb.texinfo (appendix "Installing GDB"): changes in
197 configure, and improvenets related to Pinard's refcard comments
199 Tue Oct 15 08:45:12 1991 John Gilmore (gnu at cygnus.com)
201 Changes from Fred Fish:
202 * tm-68k.h (FPI_REGNUM): Add.

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

235 generic routines for calling inferior functions.
237 * blockframe.c (inside_main_scope, inside_entry_scope): New.
239 * copying.awk: Filter formfeeds out of copying & warrantee.
240 Make them available as `show copying' and `show warrantee' also.
241 * main.c (print_gnu_advertisement): Advt `show' commands.
243 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)
245 * mach386-xdep.c: Even when cross-compiling, leave in the
246 core-file reading code.
247 * core.c (get_core_registers): Avoid coredump if no .reg section.
249 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
251 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
252 This avoids coredumps under `set print object on' in value_headof
253 (called erroneously by value_from_vtable_info) for `p &struct'
254 or `p *struct'. From Peter Schauer.
256 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
258 * Makefile.in: Roll version to 4.1.2.
259 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
260 size from BFD (but, FIXME, we don't yet read external nlists's and
261 convert them to internal nlists's before handling them -- we still
262 assume they have the same size and alignment.) Use SET_NAMESTRING
264 * exec.c (exec_file_command): Move dead coff-encapsulation code
266 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.
268 Fri Oct 4 22:30:06 1991 John Gilmore (gnu at cygnus.com)
270 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
271 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
273 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
275 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
276 * mips-xdep.c (store_inferior_registers): Don't try to
277 write the (pseudo) FP.
278 * mipsread.c (parse_partial_symbols): Improved algorithm for
279 setting pst->texthigh.
281 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
283 * doc/Makefile: make TEXINPUTS include . everywhere
285 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
287 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
288 vestiges of typevectors, which were for symsegs and are no longer
289 used. (From a question by Eliot Dresselhaus
290 <dresselh@RFT30.nas.nasa.gov>).
292 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
294 * dbxread.c, coffread.c: static-ize functions that were
295 gratuitiously external. (From Fred Fish.)
297 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
299 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
300 until it is large enough.
302 * dbxread.c (read_type): Handle error case slightly better.
303 Make complaint message not C++-specific.
305 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
307 * infrun.c (wait_for_inferior): Fix step/next so that you only
308 stop at the beginning of a new line. This fixes various problems
309 with for loops, nested if-else's and switch statements.
311 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
313 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
314 between symtabs and psymtabs become ordinary error()s.
316 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
317 properly, making "end pc" correct in shared lib psymtabs.
318 (From Guy Harris <guy@auspex.com>.)
320 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
322 * dbxread.c: Enable, but soften, const_vol_complaint.
323 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
324 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
325 should be file-scope, not global.
326 (read_struct_type): Remove ancient multiple-inheritance warning.
327 (read_range_type): Check base type, complain & patch if undefined.
328 * stack.c (frame_info): Demangle the function name in `info stack'.
331 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
333 * eval.c (evaluate_subexp_for_address): Don't use
334 TYPE_POINTER_TYPE directly (it might be zero if this type has
335 never had a pointer created before); use lookup_pointer_type.
336 * symtab.c (lookup_method_type): Arguments were swapped in all
337 callers, so fix it here. I'm amazed this worked at all!
339 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
341 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
342 "bss" rather than "data" symbols, but which still conflict.
345 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
346 * core.c (core_files_info): Shorten output.
347 * exec.c (exec_files_info): Ditto.
348 (build_section_table): Ignore zero-length sections.
349 * language.c, printcmd.c: Lint.
350 * language.h (get_frame_language): Declare.
351 * saber.suppress: update.
352 * stack.c (find_relative_frame): Remove complex code that was
353 #if 0'd, stick with simple code. Lint.
354 * saber.suppress: Update a bit.
355 * symfile.c (add_symbol_file_command): Add "?" to question.
356 * utils.c (parse_escape): Avoid \a due to bdead compilers.
357 * value.h: Declare typedef_print.
359 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
362 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
363 (Reported by Mark Peek <mark@imagen.com>.)
365 * solib.c (solib_map_sections): Relocate all sections, even
366 though only the text section's size is tracked. Mark ld_text
367 for eventual elimination as we generalize to N sections.
369 * infrun.c (wait_for_inferior): Don't check if the PC is in a
370 call_dummy if we were stopped by a random signal that is being
371 passed to the program. This produced wierd results when calling
372 functions in the inferior and signals (e.g. SIGALRM) were in use.
374 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
376 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
377 Bugfix from Paul Eggert <eggert@twinsun.com>.
378 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
379 * valprint.c (print_floating): Print 9 digits for IEEE floats.
382 Mon Sep 23 15:50:07 1991 John Gilmore (gnu at cygnus.com)
384 * Makefile.in: Roll VERSION to 4.1.1.
385 * source.c (line_info): Peter Schauer fixes a bug I introduced in
388 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
392 * Makefile.in (VERSION): Set to 4.1.
393 * language.c (set_language_command): Print useful help message,
394 and restore the language string after giving help.
395 * valprint.c (typedef_print): Print typedef in C or M2.
396 * symtab.c (list_symbols): Use it.
397 * main.c (main): Avoid any output before (gdb) prompt when -q.
398 * language.c (set_language_command): Handle errors by restoring
399 the language string to its current state (fix from A. Beers).
400 * doc/gdbint.texinfo: Roll in information from README. Rearrange
401 "how to install" and "how to print the doc" stuff so it drops
403 * configure.in: Rename rtpc CPU to romp to match config.sub.
404 * README, WHATS.NEW, TODO: Update for gdb-4.1.
406 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
408 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
409 autoloading shared libs, copyright etc on GDB startup, clean up $_
410 and $__ index refs, set/show listsize and related updates to list
411 cmd. New host/target configs.
413 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
415 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
416 from main Makefile.in version definition
417 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
419 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
421 * doc/gdb.texinfo: merge new language-switching and lang-specific
424 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
426 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
427 compilers (which may lack stddef.h).
429 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
431 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
432 N_WARNING are the same except for the N_EXT bit, so just use their
433 values alone, rather than OR-ing them with N_EXT.
435 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
437 * mipsread.c (parse_lines): Deal with negative extended line
440 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
441 global symbol conflicts.
443 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
445 * .gdbinit: Move 'set complaints' to top, so it runs even in
446 case we aren't debugging GDB.
447 * language.c (_initialize_language): Fix type check and range
448 check documentation strings.
449 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
450 language.c can use it. (Though language.c should really not be
451 handling warnings/errors the way it does, FIXME.)
452 * symtab.c (lookup_primitive_type): const lint.
454 Bugfix from Peter Schauer:
455 * source.c (lines_to_list): Make signed, to avoid comparison
456 going unsigned and complaining that -3 is too high for 21 lines.
457 * stack.c (lines_to_list): Ditto.
459 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
461 * Makefile.in (HFILES): Add minimon.h.
462 (VERSION): Roll version number to 4.0.95.
463 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
464 New rules for building distributions. Normal distribution
465 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
466 one level up from here; it calls make-proto-gdb.dir to build a
467 directory `proto-gdb' which is an image of the release. The old
468 `gdb.tar.Z' rule still works too.
469 * config.sub, configure: Roll in latest from ..
471 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
473 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
474 new-target, and new-config chapters; fix minor typos; come closer
475 to usual GNU markup conventions for @file @samp @code @var.
477 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
479 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
480 * mipsread.c (parse_partial_symbols): Enter the name of all
481 structs/unions... into the psymtab so we can access them if the
482 symtab is not read in.
483 * mips-tdep.c: Remove some unneeded #includes.
484 * xconfig/dec3100: Add HAVE_STRSTR.
486 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
488 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
489 * c-exp.y, m2-exp.y: Lint.
490 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
491 * valprint.c (val_print_fields): Check for stub type.
492 * mipsread.c (_initialize_mipsread): Avoid using
493 builtin_type_void at initialize time.
494 (mipscoff_symfile_read): use it now.
496 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
498 Merge multiple-language support, and partial Modula-2 support,
499 from Andrew Beers <beers@cs.buffalo.edu>.
501 * i387-tdep.c: New file, consolidates most 80387 support,
502 and eliminates host dependency on double<->extended conversions.
503 * i386-xdep.c, symm-xdep.c: Remove most 387 support.
504 * xconfig/i386{sco,v,v-g,v32,v32-g}: Now need i387-tdep.o.

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

595 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
597 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
598 entries are enclosed herein. Not all of these changes
599 have been merged into the master GDB sources -- check the
600 ChangeLog above here for the merge log.
602 Mon Jun 3 17:05:45 EDT 1991
604 m2-exp.y Created. Tested outside of GDB for a few days. Proper
605 operators were added, C specific operators and tokens
606 removed. yylex() revamped to some extent. Still things
607 missing from the grammar, such as sets.
608 Tested for two weeks in GDB v3.5.
610 Tue Jun 11 17:23:48 EDT 1991
612 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
613 so they are built-in. Sort of a hack.
615 Fri Jun 14 12:53:51 EDT 1991
617 m2-exp.y Added range checking for numeric constants. Any numeric
618 constant is assumed to be of builtin type INTEGER unless:
619 (1) it is octal or hexadecimal, in which case it is a
620 CARDINAL; (2) it is too big to fit into an INTEGER, in
621 which case it is a CARDINAL.
622 eval.c Added simple range checking for +, -, and * on integers.
623 Doesn't work very well for *, since 6 * 1,000,000,000 =
624 1,705,032,704, which fails the simple test of result >=
625 first_operand, no matter in what order the operands are.
627 Tue Jun 18 14:11:30 EDT 1991
629 Broke the parser into parts, one containing the C grammar and the other
630 containing code to be shared by all of the grammars.
632 The following files no longer exist:
637 The following files were added:
639 c-exp.y (The C grammar)
640 m2-exp.y (The Modula-2 grammar)
641 parser-code.c (Code that is shared by the above grammar)
645 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
646 now necessary to use the Bison compiler compiler, since it
647 will generate function/variable prefixes other than yy.
649 Tue Jun 18 16:47:49 EDT 1991
651 symtab.[ch] Added the external variable working_lang, than holds the
652 value of the current working language.
653 Added the ennumerated type language_mode, with the values
654 language_auto and language_manual, the former meaning that
655 GDB sets working_lang as needed, and the latter meaning
656 that the value of working_lang is totally under user
658 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
659 REAL, BOOLEAN and CHAR. Also added the type codes
660 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
661 utils.c Added set_language_command and show_language_command to
662 implement the GDB support commands "set language" and
664 expression.h A number of identifiers were added to the type exp_opcode
665 to facilitate Modula-2 builtin functions, integer
666 division, and array indexing.
668 Wed Jun 19 13:25:58 EDT 1991
670 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
671 if the language specified by working_lang requires the use
672 of strict typing of expressions. Eventually, even this
673 will be able to be changed by the user.
674 Added the macro RANGE_CHECK, which evaluates to non-zero
675 if the language specified by working_lang requires the
676 checking of a value against the domain of its type.
677 Eventually, even this will be able to be changed by the
679 language.[ch] Predicates involving types (simple_type, ordered_type,
680 same_type, integral_type, numeric_type, character_type,
681 boolean_type, float_type) are added. These predicates are
682 based on the current value of working_lang, and are handy
685 Wed Jun 19 15:39:34 EDT 1991
687 eval.c Added the function type_array_rank which computes the rank
689 valarith.c Added the funtion value_bool, which when given a integer
690 value.h value (ie. struct value *) as an argument, it returns a
691 boolean value (ie. struct value *) true if that integer
692 is non-zero, and a boolean value false otherwise.
693 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
694 will print out properly.
696 Wed Jun 19 16:36:34 EDT 1991
698 valops.c Added the function value_capitalize, which returns it
699 value.h argument capitalized if its argument is a lowercase
700 letter, or the argument unchanged if its argument is not a
702 valarith.c Added the function range_check_p, which returns non-zero
703 value.h if its value argument is between the integral bounds upper
705 Added the function range_check_enum_p, which makes sure
706 that its value argument is a valid member of the domain of
708 Added the function range_check_range_p, which makes sure
709 its value argument lies between the upper and lower bounds
710 of its type argument, which must be a ranged type.
711 Added the function check_array_index, which range and type
712 checks an index of an array.
713 Added the function value_multi_subscript, which computes
714 array[idx1,idx2...idxN], given a value array and an array
715 of values representing indicies.
716 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
717 unpack_long to work with TYPE_CODE_BOOL and
720 Wed Jun 19 18:04:08 EDT 1991
722 symtab.c Stored pervasive types in a structure and make
723 lookup_pervasive_type() a lookup function that was based
724 on working_lang. If lookup_pervasive_type() returned
725 non-zero, then that value was returned (a fix, since
726 before it simply wouldn't return the pervasive type.)
727 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
728 non-zero if the language specified by working_lang means
729 "conversion" when it says "cast".
730 valops.c Added the function value_real_cast(), which performs a
731 value.h *cast*, not a *conversion*, which is what value_cast()
732 does when it can. In particular,
733 value_cast(<float_type>,4) = 4.0, while
734 value_real_cast(<float_type>,4) = some mess.
735 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
736 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
737 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
738 and MIN on integral types. *NOTE*: These are currently
739 hardcoded to work only if there are 8 bits per storage
741 eval.c Made logical functions call value_bool to return a
742 properly typed boolean value, based on working_lang.
744 Thu Jun 20 11:55:27 EDT 1991
746 valprint.c Types now print out in a Modula-2 fashion. This works for
747 the cases when the type is printed out step-by-step, that
748 is, it doesn't work when the name of a structured type
749 (which includes the keyword "struct", etc.) is simply
751 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
752 since type specifications in C and Modula-2 are very
753 different. The C printing of a type is very recursive,
754 whereas in Modula-2 it is generally very simple. C has
755 type prefixes and suffixes, which have no real analogue in
756 Modula-2. Maybe type_print() should call a language
757 specific type printer. This is also advantageous if we
758 compile GDB to exclude some of the languages. We'll just
759 leave those functions out.
761 Thu Jun 20 16:57:10 EDT 1991
763 dbxread.c When reading the complete symbol table in (via
764 psymtab_to_symtab()), the number and types of function
765 arguments are added to a function type. define_symbol()
766 calls add_param_to_type() to accomplish this.
767 Assumption: when we come across a function definition
768 (N_FUN symbol with an 'f' or 'F' in the name), its
769 arguments will appear before another function definition.
770 When a function is found, a pointer to its type is placed
771 in the global in_function_type. Changes that
772 add_param_to_type() makes are to this global.
773 valprint.c The type of a function now includes (for Modula-2) the
774 types of its parameters.
775 eval.c Type checking and a check for the proper number of
776 arguments is now done for function calls. Not sure of the
777 impact this has on C++ member function yet.
779 Thu Jun 20 19:58:48 EDT 1991
781 valprint.c Rewrote the type printer. Broke it into two language
782 specific parts, adding the functions type_print_m2() and
784 An unfortunate consequence is this: if you debugging a C
785 program in Modula-2 mode (why?), info types does not work
786 well with regular expressions, since the types are printed
787 out in Modula-2 terminology, but stored in C terminology.
788 language.[ch] Added the functions new_type_last(), type_keyword(), and
789 type_sep() to aid in the printing of typedefs.
790 symtab.c Made the printing of typedefs as language independent as
791 possible through calls to new_type_last(), type_keyword(),
794 Fri Jun 21 11:50:26 EDT 1991
796 dbxread.c Check all incoming ennumerated types. If it looks like
797 Modula-2's BOOLEAN type, then change the type_code of the
798 type to TYPE_CODE_BOOL so we can process it as a boolean
800 valprint.c Replaced some of the 0x%x with calls to sprintf and
801 hexformat() in val_print().
802 language.[ch] Added the function hex_to_string(), which converts its
803 integral argument to a hexadecimal number (format is
804 language based) and returns the result as a string.
806 Mon Jun 24 12:25:07 EDT 1991
808 valprint.c Some functions call type_print_1() directly, instead of
809 value.h using type_print(), so they can specify where (column) to
810 print things. Since type_print() takes care of language
811 dependence, that needs to be called first. Added a
812 parameter depth to type_print() (so it is now like
813 type_print_1). Changed type_print to type_print_at, and
814 made type_print a macro that passes a depth argument of
816 symmisc.c Changed all calls to type_print_1 to calls to
818 Makefile.dist Made it possible to build GDB for a specific set of
819 depend languages. Do this by passing a definition for the macro
820 LANGS to make. LANGS should be a string containing a
821 space-separated list of language names (ie. LANGS="c m2").
822 The default is to build all languages. Note that grammar
823 files must follow the naming convention of <lang>-exp.y.
824 gdb.lang This holds the current value of the LANGS macro. It is
825 examined every time make is called, and is updated if
827 eval.c Added #ifdef _LANG_<lang> to these files.
828 expread.c Still need to add them to dbxread.c and coffread.c.
836 Mon Jun 24 16:33:11 EDT 1991
838 language.[ch] Added the functions hexformat_pre() and
839 hex_to_string_pre(), which take a prefix argument to
840 include in the format string. Thus, hexformat_pre("08") will
841 return "0x08x" (if the working language is language_c).
842 Made hexformat() and hex_to_string() calls to the above
843 with "" as the prefix argument.
845 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
846 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
847 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
848 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
849 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
850 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
851 valprint.c, vax-pinsn.c
853 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
854 calls to hexformat() and hex_to_string(). Format strings without
855 the leading "0x" were ignored.
857 depend Updated to take the above into account.
860 Tue Jun 25 15:27:18 EDT 1991
862 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
863 and type_check_t to keep track of the current state of
864 range and type checking.
865 main.c Added the variables range_mode, range_check, type_mode,
866 and type_check to record the current state of range and
867 type checking. Added initialization code to main().
868 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
872 Tue Jun 25 17:57:08 EDT 1991
874 dbxread.c process_one_symbol() updates the variable (enum language)
875 source_lang based on the extension of the filename
876 contained in the N_SO sybmol that started this symtab.
877 When end_symtab() is called, the value of source_lang is
878 put into the language field.
879 stack.c select_frame() sets working_lang (and possibly type_check
880 and range_check) to the language field of the symtab
881 associated with the frame that is selected if working_mode
882 is language_auto. If working_mode is language_manual, a
883 warning is printed and working_lang is not set.
884 language.c Added the function set_type_range(), which sets the value of
885 type_check and range_check (if their modes call for
886 automatic setting) based on the current value of
887 working_lang. A non-zero argument will cause the current
888 settings to be output.
891 Wed Jun 26 14:51:40 EDT 1991
893 eval.c Added range checks on assignment.
894 m2-exp.y Added the grammar for sets to the language. Currently,
895 these do not do anything except print an error message.
897 Wed Jun 26 17:01:04 EDT 1991
899 m2-exp.y Added the ability for parse_number() to parse negative
900 numbers. A global flag is set upon encountering a unary
901 minus. This was done to make, for example, 1 parse as a
902 CARDINAL, and not as an integer, per Wirth's examples in
903 Programming in Modula-2 ed.4.
904 valprint.c Added support for "set radix 2" by then setting
905 output_format to 't'.
906 eval.c Implemented range checking on subrange types. Added calls
907 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
908 Implemented MIN and MAX for ennumerated types. The
909 minimum value of an ennumerated type is defined by Wirth
910 as the first identifier, and the maximum as the last.
911 m2-exp.y Made octal numbers ending with "B" be characters and those
912 ending with "C" be numbers, per Wirth's book. (p. 34)
914 Thu Jun 27 14:11:52 EDT 1991
916 stack.c select_frame() now only sets working_lang, it does not
917 notify the user. If working_mode is language_manual, then
918 a warning is issued once.
919 main.c At the end of each call to execute_command(), working_lang
920 is checked against the local static (enum language)
921 current. If they differ and working_mode is
922 language_auto, the new settings of language, type and
923 range checking are printed out.
924 stack.c Modified frame_info() to include the language of the
925 current frame in the output of "info frame".
926 language.[ch] Added the function language_str() which returns the name
927 of the current language.
929 Fri Jun 28 15:33:14 EDT 1991
931 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
932 the language. INCL and DECL currently cause an error,
933 since sets are not implemented yet. INC and DEC are
934 implemented as PREINCREMENT/PREDECREMENT with one
935 argument, and as ASSIGN_MODIFY with two arguments.
936 eval.c Added type checking to the above cases.
937 value.h Added not_lval_constant to the lval_type ennumerated type.
938 not_lval_constant means that the value is a constant
939 value; that is 3 or 'a' or TRUE, not as in a constant
940 identifier. This is used to help coerce numbers such as 3
941 to either signed or unsigned numbers.
942 valops.c Added the function value_coerce_constants() which coerces
943 constant integers as following: if one is a constant and
944 the other is not, the constant's type is set to the type
945 of the other argument. If both are constants and one is
946 signed, the other is converted to a signed constant.
948 Sat Jun 29 17:26:29 EDT 1991
950 valarith.c Added a better range checker. It now checks range
951 (successfully) on integral operations [+-] (signed and
952 unsigned) for any C sized type. Still does not work well
954 int_in_size() returns an integer that is coerced to fit into
955 specified number of bytes.
957 Mon Jul 1 13:04:14 EDT 1991
959 language.[ch] Added the function binop_result_type(), which returns the
960 builtin (struct type *) type that would be the result of a
961 binop on the two values V1 and V2.
963 Wed Jul 3 19:22:53 EDT 1991
965 source.c Extended source_info() to include the source language in
966 the output from "info source".
968 Fri Jul 5 13:48:52 EDT 1991
970 utils.c Moved the support functions for the GDB set/show commands
971 dealing with language into language.c.
972 language.c Added the function language_info(), which displays info
973 about the current working language, type and range check
974 settings. Called via the GDB command "info language".
975 Added an initialization routine _initialize_language(),
976 that sets defaults for the language, type and range
977 variables and sets up the new GDB commands.
978 main.c Language setup moved to language.c.
981 Mon Jul 8 10:10:22 EDT 1991
983 valarith.c Debugged the range checker for arithmetic. Still does not
984 work for multiplication very well.
986 Mon Jul 8 12:40:37 EDT 1991
988 language.[ch] Added the function value_true() which returns non-zero if
989 its argument represents a boolean true value.
990 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
991 check the truth of an expression.
993 Thu Jul 11 12:51:34 EDT 1991
995 language.[ch] Added the predicate structured_type(), which returns
996 non-zero if the argument is a structured type.
997 Added the predicate pointer_type(), which returns non-zero
998 if the argument is a pointer type.
999 eval.c Added the ability to do addition and substraction on
1000 pointers and integers. This case simply bypasses the
1003 Thu Jul 11 14:41:42 EDT 1991
1006 Added the symbol N_DEFD (0x4a) which is a definition
1007 module dependency that is used by the GNU Modula-2
1008 compiler and the linker. It is not important to GDB,
1009 except that [dbx|coff|mips]read.c should ignore these
1012 Fri Jul 12 16:07:00 EDT 1991
1014 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1015 0 in val_print(). Also added statements to the else part
1016 to coerce type (argument to val_print) to a pointer type
1017 if it is an "array of unspecified length".
1018 valops.c Added the function value_m2_string(), which returns a
1019 (value) value which is a constant string, whose type is
1020 (ARRAY [0..n] OF CHAR). The length field of the type
1021 structure is set to zero, so it will be interpreted as an
1022 "array of unspecified length".
1023 stack.c Moved the language/frame mismatch check to
1024 main.c:execute_command().
1025 main.c The working language is recorded each time
1026 execute_command() is executed. If working lang has
1027 changed during its execution, then the new
1028 language/type/range info is printed out for the user. If
1029 the working language does not match the language of the
1030 frame, a warning is issued.
1032 Sat Jul 13 16:16:39 EDT 1991
1034 eval.c Moved all the type-checking stuff for operators to
1035 language.[ch] language.c. This is so we can keep language-specific
1036 stuff (like for what type operators are defined) in
1038 language.[ch] Added the function binop_type_check(), which checks to see
1039 if its two (value) arguments are type-compatible with its
1040 opcode argument. The opcode should represent an operation
1041 involving an operator. Also added the macro function
1042 unop_type_check, which calls binop_type_check with a
1043 NULL second argument.
1044 expprint.c Added Modula-2 operators to the op_print_tab, so info
1045 expression.h break works correctly. Also added "op_string", which
1046 returns the string corresponding to the (enum exp_opcode)
1047 opcode that is its argument.
1050 Sat Jul 13 18:26:18 EDT 1991
1052 coffread.c Added code to record the type of function arguments with
1053 each paricular function. Code is very similar to that
1055 dbxread.c Moved add_param_to_type() to symtab.c
1056 symtab.[ch] Added function add_param_to_type() from dbxread.c
1058 *** NOTE: The above additions have not been tested.
1060 Mon Jul 15 12:50:47 EDT 1991
1062 langauge.[ch] Added the functions type_error and range_error, which work
1063 like error() except if the type/range mode is set to
1064 *_mode_warn, then they do not do a return_to_top_level(),
1065 but merely print a warning.
1066 Also changed [set|show]_[type|range]_command() to support
1067 the new "warn" feature.
1069 Thu Jul 18 17:50:54 EDT 1991
1071 mipsread.c Added code to record the type of function arguments with
1072 each particular function. Code is very similar to that
1075 *** NOTE: The above additions have not been tested.
1077 Fri Jul 19 11:19:10 EDT 1991
1079 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1080 UMIN_OF_SIZE, which when given a size of a numeric type,
1081 return the maximum and minimum value it can hold. UMAX...
1082 and UMIN... return the result for unsigned types.
1083 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1084 struct types. They call above macros.
1085 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1086 avoid a name conlict with the above.
1087 c-exp.y Added range checking on numeric constants in
1088 parse_number() for completeness.
1089 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1090 return 0 if working_lang is not language_c.
1092 Thu Aug 8 14:17:22 EDT 1991
1096 breakpoint.c Documentation strings of some commands changed to
1097 eliminate the references to the C language where
1100 Tue Aug 13 15:48:03 EDT 1991
1102 m2-exp.y Added qualified identifiers to the grammar. The semantics
1103 are slightly different from those of the GDB operator ::
1105 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1106 type_exp, where type_exp is any valid type expression.
1108 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1109 printcmd.c Modified ptype_command() so it actually parses the input
1110 (necessary for type expressions with scope qualifiers).
1111 Added the function ptype_eval() which expects an
1112 expression composed of one OP_TYPE element.
1113 *.[ch] Replaced all occurences of parse_c_expression with
1115 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1117 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1119 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1121 Small fixes from Peter Schauer:
1123 * infrun.c (child_attach): Lint.
1124 * solib.c (find_solib): Handle shared libs version 2.
1126 Small fixes from David Wood:
1128 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1132 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1133 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1135 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1136 chars_per_line is at maximum (user typed `set width 0'). Fix
1137 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1139 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1141 * coredep.c: include ptrace.h where necessary.
1142 * mipsread.c(parse_lines): fix unsigned char problem that was
1143 messing up line numbers on SGI's and possibly other MIPS based
1145 * infrun.c (child_create_inferior): use better test to check
1146 return val from setpgrp().
1147 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1148 for sgi/irix support.
1150 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1152 * mipsread.c (parse_symbol): Put non-static procedures
1153 in the global block.
1155 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1157 Patch together `text_start' and `text_end' for 29K port.
1159 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1160 variables and set them based on the exec file.
1161 * am29k-tdep.c: declare text_start.
1162 * valops.c (call_function_by_hand): declare text_end.
1164 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1165 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1166 because machines that do this will also have to know to
1167 set NEED_TEXT_START_END. Besides, it was a redundant way to
1169 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1170 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1171 NEED_TEXT_START_END.
1173 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1175 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1177 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1178 Pass MUNCH_DEFINE to munch whenever we run it.
1179 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1180 format string; use 0x%x instead.
1181 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1182 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1183 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1184 * inflow.c: Handle `short' process group IDs.
1185 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1186 and check for ptrace errors.
1187 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1188 (coff_symfile_init): Initialize text_bfd_scnum.
1189 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1190 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1191 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1192 Merge target arm case with other "easy" cases. Add target
1193 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1194 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1196 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1197 * munch: Cope with RT/PC putting fns in data segment.
1198 Restore ability to override `nm' by specifying MUNCH_NM.
1199 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1200 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1201 and remote-adapt. Remove encapsulated coff #define's (the
1202 support should go in BFD, and gdb shouldn't know or care).
1203 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1204 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1205 * tm-29k.h: Update BADMAG (though it should go away).
1206 Allow the register definitions to be overridden in another
1207 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1208 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1209 DUMMY_SAVE_GR96, for handling kernel calling conventions
1210 that use GR64+ rather than GR96+.
1211 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1212 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1213 overrides various things.
1215 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1216 child_attach does, making a clean stop in the newly attached
1218 * remote-eb.c: Lint.
1220 * coffread.c: Make coffread independent of any particular
1221 variant of COFF. Avoid #include-ing any particular one except
1222 internalcoff.h. BFD now passes key values for symbol reading
1223 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1224 and the symbol masks and shifts); use them.
1225 Remove obsolete end_of_text_addr.
1227 * exec.c: Remove unused include files.
1229 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1231 * Makefile.in (documentation targets): Pass $(M4).
1232 Bugfix from eggert@twinsun.com (Paul Eggert).
1234 * stack.c (down_silently_command): Check for stack existence.
1236 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1238 * Makefile.in (VERSION): Update to 4.0.3.
1240 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1242 * core.c (core_file_command): Print frame at coredump with
1243 its level number, by calling print_stack_frame.
1244 * frame.h: Add selected_frame_level, print_stack_frame.
1245 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1246 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1247 Change print_sel_frame and print_selected_frame callers to
1250 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1251 * symfile.c (free_named_symtabs): Ditto.
1252 * main.c (main): wrap_here needs an arg.
1253 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1254 (solib_add): Avoid noise.
1255 (solib_create_inferior_hook): Lint.
1256 (sharedlibrary_command): Move dont_repeat to here.
1257 * utils.c (error): Call wrap_here to force buffered output.
1259 Small patches from Peter Schauer:
1261 * coffread.c (start_symtab): Free any existing line_vector before
1263 (read_coff_symtab): Ditto for type_vector.
1265 * source.c (lines_to_list): New variable, replacing function.
1266 (all uses): Use as variable.
1267 (_initialize_source): Add 'set listsize' and 'show listsize'.
1268 * utils.c (lines_to_list): Remove function.
1269 * stack.c (print_frame_info): Use as variable.
1270 * defs.h (lines_to_list): Remove declaration.
1272 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1274 * breakpoint.c (insert_breakpoints): Restore warning about
1275 the program might be running in another process, but only for
1276 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1277 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1279 * utils.c (error): if error_pre_print is set, print the string
1281 * main.c (main, print_gnu_advertisement, print_gdb_version):
1282 Reformat legalese so it always prints, but acts as an "I'm here"
1283 message while symbols are being read. If any errors occur,
1284 print a few newlines to set off the message and start it at the
1285 left margin. Remove mention of "help" command, and don't yak
1286 about symbol reading.
1287 (catch_errors): Error string is now printed first in case of
1289 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1290 suggest the "help" command.
1292 * Makefile.in (VERSION): Set to 4.0.2.
1294 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1296 * .gdbinit: Remove useless "rr" command. Set complaints
1297 to 1 for people debugging gdb.
1299 * breakpoint.c, remote-vx.c: Reword strings printed by
1300 catch_errors callers.
1302 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1304 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1305 (Fix from kenc@viewlogic.com.)
1307 Fix some infrastructure to be able to cope with host and target
1308 machines with different sized basic types (ints, ptrs, etc).
1309 (Idea from pierre@la.tce.com (Pierre Willard).)
1311 * values.c (value_from_longest): Rename from value_from_long.
1312 Handle pointer types as well as integers, so that targets with
1313 different pointer sizes from the host can be accomodated.
1314 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1315 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1316 uses of value_from_long to value_from_longest.
1317 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1318 the correct pointer type to value_from_long{est}.
1320 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1322 * remote-vx.c: Remove obsolete code for calling functions via
1323 vxworks kludge interface (it referenced value_from_long).
1325 * valops.c (value_string): Find malloc with lookup_misc_func, not
1328 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1330 Make writing to files work properly. (Fixes to BFD are also needed.)
1332 * core.c (core_open): Open file ourselves, read or r/w, depending on
1333 write_files. Use bfd_fdopenr.
1334 * gdbcore.h (write_files): New variable.
1335 * exec.c (write_files): Define variable, add set&show for it.
1336 (exec_file_command): Use write_files to open for read or r/write.
1338 Make shared library reading happen automatically. These changes
1339 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1341 * inferior.h (stop_soon_quietly): Add to exported variables.
1342 * infrun.c (child_create_inferior): call solib hook, if defined.
1343 (child_attach): call solib hook, if defined.
1344 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1345 (find_solib): Use lookup_misc_func rather than hand-rolled.
1346 (symbol_add_stub): New stub for catch_errors.
1347 (solib_add): Avoid output if !from_tty. Catch errors rather
1348 than just calling symbol_file_add and bombing.
1349 (solib_create_inferior_hook): Interface with the target process
1350 to let it read and alloc shared libs, then figure out what it did.
1352 * core.c (validate_files): Fix typo, soften warning.
1353 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1355 * utils.c (fputs_demangled): Avoid duplicate printing if
1356 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1358 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1359 (Fix from pierre@la.tce.com (Pierre Willard).)
1361 * main.c (catch_errors): Change argument to a char * from an int,
1362 since a char * can point to a struct full of glop, but an int
1363 is not guaranteed to be able to hold a pointer.
1364 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1365 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1366 * core.c (core_open, solib_add_stub): Adapt.
1367 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1369 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1371 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1372 by adding .NOEXPORT target.
1374 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1378 * Makefile.in (VERSION): Roll to 4.0.
1379 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1381 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1383 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1386 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1389 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1391 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1392 reflect above name change
1394 * WHATS.NEW: correct pointer to refcard.
1396 * doc/gdb.texinfo: update New Features, Installing
1398 * doc/gdbint.texinfo: add short description of configure +template
1400 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1402 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1404 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1406 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1407 tar file, add dependencies for referenced doc files.
1409 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1411 * coffread.c, symfile.c, stack.c: saberized.
1413 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1415 * doc/refcard.tex: permuted Essential Commands sec
1417 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1419 set/show symbol-reloading
1420 default set complaints 0
1422 RET-repeat disabled after prompted long displays
1423 processID (attach) interpretation of 2nd GDB cmdline arg
1425 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1427 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1428 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1429 breakpoint.c, main.c: lint.
1431 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1433 Install new configuration scheme for GDB and friends.
1435 * config.sub: Translate ordinary names to three-part names.
1436 * configure: Use three-part names internally.
1437 * configure.in: Translate three-part names to filenames.
1439 * README, WHATS.NEW: Update for gdb-4.0.
1440 * Makefile.in: Roll VERSION to 3.99.
1442 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1444 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1445 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1446 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1447 to single structures rather than arrays; when passing
1448 their address, use &. This avoids trouble with bdead compilers.
1449 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1450 instead. This avoids portability headaches.
1451 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1453 * source.c (open_source_file): Avoid ANSI const bdeath by
1454 skipping declaration and then casting result value.
1455 * tm-hp300bsd.h: Clarify comment.
1456 * utils.c (strstr): Result is const char *; ANSI bdeath.
1457 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1458 since system include file defines it differently from "defs.h",
1459 though the two are equivalent for our purposes.
1460 * tconfig/hp300bsd: Add m68k-tdep.o.
1462 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1464 * tconfig/sun*4: Remove warnings about system assembler.
1466 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1468 * mcheck.c: Avoid warning about undeclared abort fn.
1469 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1470 it causes recursive calls to error() when used in cleanups.
1471 To do so requires that we make it a function, so we do.
1472 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1473 * utils.c (do_cleanups): Remove the current cleanup from the
1474 chain *before* calling it, in case error() is called from it.
1475 The result won't be pretty, but won't be an infinite loop either.
1477 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1479 * dbxread.c (read_struct_type): Grok anon structs for C++.
1480 (vb_name, vptr_name): Null terminate these strings.
1482 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1484 Minor bug fixes from BSD Net2 gdb:
1486 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1487 returns 0, there is no previous frame.
1488 * breakpoint.c (commands_command): If !from_tty, don't call
1489 input_from_terminal_p().
1490 * dbxread.c (record_misc_function): Speed up slightly.
1491 (compare_psymbols): Ditto.
1492 * infcmd.c (do_registers_info): Take a second argument to
1493 determine whether to print float registers. "info registers"
1494 does not do so anymore. "info all-registers" does, now.
1495 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1497 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1498 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1502 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1503 executing_breakpoint_commands if we are interrupted by error.
1504 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1505 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1506 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1507 catch_errors() so we can setup the frame regardless of whether
1508 the shared libs work.
1509 * ieee-float.c (double_to_ieee_extended): Get exponent from
1510 right place in little-endian systems. From John Carey.
1512 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1514 * main.c: Remove unused terminating_signals and catch_termination().
1515 (long_options): Terminate with a zero element.
1516 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1517 (gdb_readline): Make call-compatible with readline.
1518 (init_signals): Improve comments re vfork vs. signal.
1520 * utils.c (prompt_for_continue): Use new gdb_readline().
1521 If we prompt for continuation, we don't let CR repeat the previous
1522 command, once we get back to a prompt. It's too easy to keep
1523 hitting CR, expecting "--more--" prompts, and have some long
1524 command start repeating on you.
1526 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1528 * blockframe.c (frameless_look_for_prologue): Speed up by
1529 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1530 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1531 Define two variants, one faster.
1532 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1533 and return zero, rather than giving an error.
1534 (setup_arbitrary_frame): Initialize the PC in the new frame.
1535 (skip_prologue): Add a second arg saying whether we're just
1536 checking for a frameless function or not.
1538 * core.c (core_open, core_close, core_xfer_memory): Move
1539 section table pointers and bfd* into the target_ops.
1540 (core_open): Allow errors in shared lib reading, etc.
1541 (core_files_info): Describe shared library sections.
1543 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1544 exec_files_info, set_section_command): Move section table
1545 pointers and bfd* into the target_ops.
1546 (add_to_section_table): Add BFD to section table.
1548 * target.c (target_xfer_memory, target_info): Pass target to
1549 xfer_memory and target_info functions.
1552 * gdbcore.h: Move struct section_table.
1553 * target.h: New home of struct section_table.
1555 * solib.c (solib_add): New argument is the target_ops whose
1556 section list is to be added to, if any. Reallocate the
1557 sections in that target to add any that come from shared libs.
1558 (throughout) so_sections renamed to sections.
1559 (solib_xfer_memory): Deleted.
1560 * tm-sunos.h (SOLIB_ADD): Add target argument.
1561 (SOLIB_XFER_MEMORY): Delete.
1563 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1564 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1565 from target_ops. It's the same on all targets. Add two section
1566 pointers to target_ops.
1568 * stack.c (find_relative_frame): Dump ancient algorithm for
1569 "down", just use handy "next" pointers.
1570 (frame_command): Don't error if there is no stack; let user
1573 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1574 modifies static state in the parent process; new_tty itself
1575 runs in the child and modifies the child's file descriptors
1576 to match the saved static state.
1577 * infrun.c (child_create_inferior): Call new_tty_prefork,
1580 * infptrace.c (child_xfer_memory): Add ignored target arg.
1581 * remote-eb.c (eb_xfer_inferior_memory): ''
1582 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1583 * remote-vx.c (vx_xfer_memory): ''
1584 * remote.c (remote_xfer_memory): ''. Rename from
1585 remote_xfer_inferior_memory.
1587 * main.c (main): Only try to attach "corefile" argument if
1588 it starts with a digit.
1590 * symfile.c (symbol_reloading): New "set/show" variable.
1591 (symbol_file_add): Shorten message about symbol reading.
1592 (add_symbol_file_command): Merge with add_syms_addr_command,
1593 since this should work on all targets now.
1594 (stop_whining): Default to zero, to shut up complaints
1595 about bad symbol tables on many systems.
1596 (free_named_symtabs): Just exit unless symbol_reloading.
1598 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1599 and add comment explaining shared library screw.
1601 * source.c: #if defined => #ifdef.
1603 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1605 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1607 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1609 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1610 (doc/Makefile knows how to make one for local config)
1612 * Makefile.in: use doc/Makefile for doc targets
1614 * doc/Makefile: GDB documentation now has its own Makefile
1615 doc/refcard.tex: renamed from "gdbrc.tex"
1616 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1617 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1620 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1622 * values.c (baseclass_addr): When reading target memory, use the
1623 length of the basetype, not the upper type. We've only malloc'd
1624 enough space for the basetype, leading to errors in free().
1626 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1627 ends up as a function specially, since we know the actual type of
1628 the pointed-to address. This (somewhat) fixes display of
1629 expressions that include misc_function_vector names. Try `cond 1
1630 !strcmp("a","b")' then `i b'.
1632 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1633 The child can be proceeded from inside wait_for_inferior in
1634 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1635 getting skipped in that case.
1637 * expprint.c (print_subexp): Use filtered output, since the
1638 subroutines we call use it, otherwise the output is horribly
1639 mangled, since output of wrappable stuff comes out late.
1641 * Makefile.in: Bump VERSION to 3.98.1
1643 * infrun.c (child_create_process): Use execlp to find the
1644 shell to exec our target program. This requires some fiddling
1645 with `environ' since there is no execlpe().
1647 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1649 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1650 Minor rearrangement of refcard permits two new make targets--
1651 gdbrc.dvi DVI output for refcard, using CM fonts
1652 gdbrc.ps PostScript refcard, using PS fonts
1654 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1658 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1659 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1661 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1663 * doc/gdb.texinfo: last changes for release.
1664 Minor typo and formatting fixes; incorporated most fixes remaining from
1665 filed mail commenting on earlier drafts.
1667 Added warnings: pipes don't work in run command;
1668 conditions are converse of assertions;
1669 step over fn without debug info goes to next fn;
1670 vars may have "wrong" values near fn entrance, exit
1672 Added example from Kingston on printing repeated nonadjacent values
1674 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1675 shell mode for signals
1677 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1678 doesn't sound so much like its parent "Stopping and Continuing"; also
1679 moved entries on continue to top of section, so they don't get lost.
1681 Improved installation directions in appendix, added manual formatting
1684 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1686 * configure.in: Remove xm.h and tm.h even if we aren't linking
1687 new ones, so "./configure sun4; ./configure none" does the right
1688 thing. Assume that alldeps.mak and depend are already built in
1689 srcdir, and avoid running "make" (particularly "make depend",
1690 which involves "gcc") from inside configure. Build Makefile
1691 directly rather than building Makefile.conf first.
1692 * configure: Regenerate with above changes.
1693 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1694 to 3.98. Revise gdb.tar.Z procedure to produce a file
1695 called gdb-$(VERSION).tar.Z but which unpacks into a
1696 directory called "gdb". Move non-source files out of
1697 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1698 (depend): Don't try to do "gcc expread.y".
1699 (expread.o): Update dependencies by hand.
1701 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1704 Fixed a variety of small typos that prevented info from formatting
1705 cleanly; altered too-long heading for GPL Appendix, as discussed
1706 w/RMS; Changed date on cover to July 91.
1708 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1711 (1) Applied some fixes due to comments from Larry Breed (easier ones
1712 through chapsec 5.2)
1713 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1714 it's broken in latest texinfo
1715 (3) Introduced *some* use of [] for optional arguments, where
1716 explanation is not simpler by listing cmd w arg and cmd w/out arg
1717 separately. Still not using @deffn.
1718 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1719 couple of headings are too long. Need patches to texinfo or revision
1722 * Partial update to README (which still needs work for this
1723 release!): (1) use of configure corrected for new script,
1724 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1726 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1728 * symtab.c (lookup_symbol): Don't complain right off about
1729 no debug symbols; use the misc function vector first.
1730 (list_symbols): Use misc function vector to find symbols
1731 that don't have debug info, and print them.
1732 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1733 PC range doesn't match symtab PC range, as it does on the
1734 MIPS because our symtab reading isn't perfect.
1736 * dbxread.c (dbx_symfile_read): Make warning about
1737 "no debug symbols" slightly nicer.
1739 * source.c (select_source_symtab): If "main" symbol exists,
1740 but decode_line_spec can't find line info, don't just return
1741 a zero; try other source symtabs or give an error.
1743 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1744 their low addresses first, then rip through fixing high addrs.
1746 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1747 <runene@ifi.uio.no>.
1748 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1750 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1752 * Minor, mostly mechanical, cleanup of doc subdir for clean
1753 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1754 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1756 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
1758 Mostly MIPS and general symbol-reading fixups.
1760 * doc/gdbint.texinfo: Add documentation on symbol-reading
1763 * mipsread.c: Remove kludges around #include "ecoff.h".
1764 Remove redefinitions of a_magic, etc, no longer used.
1765 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
1766 Fix global overview comments to match symfile.c protocol.
1767 (mipscoff_new_init): Eliminate cur_hdr if we have one.
1768 (mipscoff_symfile_read): Eliminate unused code. Avoid
1769 sorting all the symtabs, when all we have read here is psymtabs.
1770 The symtabs are sorted as they are created anyway. Tell
1771 condense_misc_bunches whether we're mainline.
1772 (psymtab_to_symtab_1): Pass filename when recursing, to make
1773 stack trace more informative.
1774 (parse_partial_symbols): Assume cur_hdr as argument.
1775 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
1776 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
1777 the TYPE_NAME of char *, since that's done in symfile.c.
1778 (free_numargs, parse_symbol, add_symbol, add_block,
1779 shrink_linetable): Declare these fns void.
1780 (upgrade_type): Convert tree of if's to switch. Clean up
1781 bogus "off == 0" handling with a complaint. Avoid setting
1782 field bitpos and bitsize of array with lower and upper bounds.
1783 Check specified bitsize of elements against their actual type's
1784 bitsize, and complain if different. Complain about unknown
1786 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
1787 (psymtab_to_symtab_1): Print names of subsidiary files that
1788 are being read in. FIXME, we read far too many files. This code
1789 is not the problem, the problem is in parse_fdr where the psymtabs
1791 (cross_ref): Result should indicate that we used one aux entry
1792 normally, or two if we encountered a "next" entry. This used
1793 to leave the caller pointing at the wrong aux entry.
1794 (add_symbol): If overflowed cur_block, reallocate it larger,
1795 chase all pointers to it, and complain(), rather than clobber memory.
1796 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
1797 (new_field): Only allocate one field initially, not two.
1798 Pull ++ out of macro argument. Simplify.
1799 (_initialize_mipsread): Avoid initialization of importd
1800 global_psymbols and static_psymbols.
1802 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
1803 to properly set pst->symtab; avoid searching for it.
1804 (symfile_fns): Improve comments, add a FIXME.
1805 * dbxread.c: Update comments to reflect symfile protocol.
1806 (read_ofile_symtab, end_symtab): Return the symtab.
1807 (psymtab_to_symtab_1): Set pst->symtab.
1809 * coffread.c (coff_symfile_read): tell condense_misc_bunches
1810 whether we're mainline.
1812 * symfile.h (sym_fns): Remove unused sym_discard member.
1813 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
1815 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
1816 the environment variable is not.
1817 * infcmd.c (finish_command): Use filtered printfs.
1818 * cplus-dem.c: Add struct tags to a few unnamed structs.
1819 * valops.c (value_coerce_array): Improve comments.
1820 * valprint.c (type_print_varspec_suffix): Print array size only
1821 if greater than zero.
1822 * m88k-tdep.c: Shift some lines left by one space, that had
1823 apparently been trashed at some point.
1824 * TODO: More things to do, a few got done.
1826 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1828 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
1829 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
1831 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
1832 * expread.y, findvar.c, symmisc.c: Ditto.
1833 * printcmd.c (address_info): Update printed forms of LOC_
1834 symbols. Elim LOC_EXTERNAL.
1835 (print_frame_args): Keep track of param stack offsets before
1836 re-looking up to find the local register param is kept in.
1838 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
1839 Further integration of mipsread into gdb. Eliminate unused
1840 routines, duplicate declarations. Handle static symbols in
1841 psymtabs as well as external symbols. When reading symtabs,
1842 insert symbols into the correct block (global, static, or a local
1844 (read_mips_symtab, parse_partial_symbols): Don't pass useless
1846 (mipscoff_symfile_read): Don't call select_source_symtab.
1847 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
1848 rather than SYMBOL_VALUE.
1849 (parse_external): Comment clobbering of top_stack.
1850 (parse_partial_symbols): Update comments. Allocate and parse
1851 static symbols as well as external symbols. FIXME, enum values
1852 are not handled in this pass, but should be. Inline new_psymbol.
1853 Use SYMBOL_VALUE_ADDRESS.
1854 (psymtab_to_symtab_1): Read symbols into global static block
1855 by default (until enter some function's local block context).
1856 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
1857 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
1859 * source.c (select_source_symtab): Select a source symtab
1860 from either the symtabs or, failing that, the psymtabs.
1861 (list_command): Update error message.
1862 (forward_search_command, reverse_search_command): Use getc, not
1863 fgetc, for speed. FIXME, add comment about buffers that die if
1864 overrun by long line.
1866 * values.c (unpack_field_as_long, modify_field): Avoid shifting
1867 by an entire word, which is not portable, if we have a 32-bit
1868 field. (Code in dbxread.c already turns such bitfields, if
1869 aligned, into ordinary ints, but fixing this will help for other
1870 symbol formats and for future changes.)
1871 * core.c (core_open): Handle ANSI const brain death.
1872 * utils.c (vprintf): Fix varargs typo.
1874 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1876 * findvar.c (find_var_value): Handle &function better.
1877 * TODO: Document work needed on &fn and &array.
1878 * printcmd.c (print_address_symbolic): New arg is the prefix
1879 to print if a name is printed.
1880 (print_address_demangle): Honor "set print address" now.
1881 Use new arg above to improve spacing of output.
1882 * valprint.c (val_print): When printing function pointers,
1883 print symbolic form too.
1884 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
1886 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1888 * core.c (memory_error): Reword error msg to mislead less.
1890 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
1892 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
1893 parse_partial_symbols): Use newer BFD internals (external_filehdr
1894 and external_aouthdr), byte-swap the fields that we care about
1895 before using them, and make the file header data local to
1896 read_the_mips_symtab rather than global.
1898 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
1900 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
1901 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
1903 * main.c (command_line_input): Flush stdout and stderr
1904 before every call to readline. This reportedly fixes a bug
1905 that comes up in Sys V running emacs-gdb and/or xxgdb,
1906 when stdin/out are pipes or sockets.
1908 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1910 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
1911 Avoid declaring Makefile dependencies, because GNU Make stupidly
1912 tries to update it if we do.
1914 * coffread.c: Revise for minor changes to bfd internal coff
1917 * configure: If -template= is given a relative path, make it
1918 absolute before recurring in subdirectories.
1920 * configure, configure.in, Makefile.in: Install "configure" script
1921 as replacement for config.gdb.
1922 * config.gdb, Makefile.dist, Makefile.sdir: Remove
1923 * README: Update for configure, mostly. FIXME.
1925 * Add dec3100 as equivalent to littlemips. Indicate in all host &
1926 target config files that they are for the host. When the lines
1927 get copied into the Makefile, this makes it more obvious what's
1930 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1932 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
1933 tabs, which end up in the disassembler output inadvertently.
1935 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1937 Make it compile cleanly in an ANSI GCC2 environment.
1939 * blockframe.c: <stdio.h>
1940 * cplus-dem.c: free takes a void *, ifdef __STDC__
1941 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
1943 * defs.h (alloca): Avoid doing anything if alloca already def'd.
1944 * stddef.h, stdlib.h: Remove these files.
1945 * symtab.c: Avoid declaring qsort, close.
1946 * symfile.c: Avoid declaring close.
1947 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
1948 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
1950 Assorted other changes.
1951 * dbxread.c: include "libaout.h", not "liba.out.h".
1952 * printcmd.c (print_frame_args): Set recurse properly for
1953 indentation of struct and array parameters.
1954 * valops.c (value_cast): Allow cast to void.
1955 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
1956 single_step() in a target-independent fashion.
1957 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
1958 set up to be ready to continue. This makes us target independent.
1959 * infptrace.c (child_resume): Remove call to single_step; now
1960 can single step a SPARC target of any kind.
1962 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1964 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
1965 docn into separate sections---basically chapters, plus two loose
1966 pieces that can be configured to go in different places. This
1967 allows GNU m4 to preprocess the manual without coredumping.
1969 * Makefile.dist: tell TeX where to find texinfo.
1971 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1973 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
1974 the new target "rdl-apps.texinfo" which captures the Makefile
1975 variable that records where to find the Readline libraries.
1977 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
1979 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
1980 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
1981 * defs.h (const, volatile): Only define if not already defined.
1982 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
1984 * README: Update for release 3.95.
1985 * config.gdb: Don't create readline dir in subdir builds.
1986 * main.c: Include with "..." form for non-system include files,
1987 so "gcc -MM" for "make depend" works.
1988 Include readline files with "...h" rather than <readline/...h>.
1989 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
1991 * coffread.c: Undo minor damage done by Rich Pixley. Use
1992 different internal and external representations of COFF
1993 data structures. Use new BFD routines for swapping them in and
1995 * symfile.c (free_named_symtabs): Avoid freeing file names that
1996 are null or empty. Old i960 tools seem to produce files that
1997 claim to have empty names, causing each successive file read
1998 to blow away the previous one.
1999 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2000 Move deferred_stores to top of file, but don't separate its
2001 #define's from its variable. Add commentary.
2002 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2003 favor of keeping the (working) config.gdb. Move readline

2018 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2019 applied various small fixes due to or inspired by RMS comments
2021 * doc/gdb.texinfo: finished using all RMS comments, save those for
2022 appendices on readline and cmd history (which are in other source
2025 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2027 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2028 chapter 9; (2) documented 'break' command's menu mode for
2029 overloaded names, in response to hgs problem report C++ p-31
2031 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2033 * doc/gdb.texinfo: (1) better introductory example; (2) more
2034 consistent use of @code, @samp, @file, @kbd throughout; small
2035 cleanups to first three nodes; (3) new "Contributors" node;
2036 (4) Appendix, Renamed Commands; (5) divert specialized startup
2037 instructions to "Targets" chapter for generic manuals, while
2038 leaving them up front for manuals specific to specialized
2039 environments; (6) apply fixes from RMS comments through chapter 4.
2041 * pretex.m4: modify explanatory text slightly (and redefine
2042 "regexp") to keep GNU m4 from complaining. (It still crashes
2043 later, but one step at a time...)

2047 * readline/readline.c (update_line): Avoid dereferencing a pointer
2048 before comparing it to its bounds. Saber caught this.
2049 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2050 and only set PC if tgetstr returned non-null. Saber caught this.

2055 stuff for config manual) here where it counts; updated
2056 to use new subdir structure (gdb/doc/).
2058 * Makefile: generated from above via
2062 * gdbint.texinfo: added instructions on generating gdb.info* files
2063 locally for release. These are ordinary info
2064 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2065 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2066 to generate these, so we distribute them already formatted.
2068 * gdb.texinfo: included full Info node and menu crud (as generated
2069 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2071 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2072 put in comments-for-future gdb.info target (one day makeinfo will
2075 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2077 * gdb.texinfo: Updated to include new or old undocumented
2078 commands, at least the following (perhaps some others I forgot to
2079 record): info f, info float, info path, info program, info s, info
2080 set, info source, info terminal, info types, info user, set/show
2082 Also covered all recent GDB command renames for v4.
2084 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2086 * mipsread.c: Rather than keeping count of how many symtabs
2087 and psymtabs we have, for sorting purposes, count them when
2088 we need to sort. This fixes bug in rereading of symbol tables.
2090 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)

2107 symtab.h, target.c, target.h: Lint.
2108 * core.c: setup and select frame after reading shared libs,
2109 else reading shared libs will clobber them. Lint.
2110 * utils.c (error): Force out any buffered wrap text.
2112 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2114 * remote.c: Remove decls of memory_insert_breakpoint
2115 and memory_remove_breakpoint, no longer used. (Suggestion of
2118 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2119 to make it easier to interface to "configure"'d libraries.
2121 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2123 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
2124 aliases for set/show print.

2554 defined, define it to '$'.
2556 * arm-opcode.h: New file (same contents as before; it had
2557 just been left out of the distribution for a long time).

2628 New function to give correct error message.
2630 Thu Apr 11 17:19:41 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

2633 target.c: Add target_preopen and target_command.
2635 (add_target): Call add_cmd and mess with targetlist->doc.
2636 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
2637 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.
2638 Call target_preopen from open routine.
2640 * main.c: Rename editing_info to show_commands.

2662 * symmisc.c (same): same.
2663 (free_symtab): Make non-static.
2664 * symtab.h (free_symtab): Declare as exported void fn now.
2665 * dbxread.c (end_symtab, end_psymtab): Change comments.
2666 (initialize_dbxread): Call dbx_new_init() in case the first
2667 command is add-symbols.
2668 * target.c (dummy_target): Permit add_syms_addr_command.
2670 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2672 Permit symbols to be superseded when new symbol files have
2673 been read in, particularly for VxWorks.
2675 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
2676 to the main file, as well as to include files. Also, put global
2677 functions into the global psymtab, to make "i fun" work.
2678 (end_psymtab): Free named symtabs and psymtabs for a file, once a
2679 new psymtab for it has been read.
2680 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
2681 a file, once a new symtab has been read for it.
2682 * mipsread.c: FIXME. We need to do the same for MIPS, but it
2683 looks harder to determine the top-level block before it's been
2684 queued to the psymtab list.
2686 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
2687 If we have wiped out any old symbol tables, clean up at end of
2689 (symbol_file_command): Don't reference symfile_fns if it's zero.
2691 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
2692 defines for the blocks of a blockvector that contain global and
2693 file-static symbols and the first of the smaller scope contours.
2694 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
2695 decode_line_1, make_symbol_completion_list): Use the above.
2696 * coffread.c (end_symtab, patch_opaque_types): Ditto.
2697 * dbxread.c (end_symtab): Ditto.
2698 * expread.y (block): Ditto.
2699 * mipsread.c (throughout): Ditto.
2700 * symmisc.c (free_named_symtabs): Ditto.
2702 * symtab.c (list_symbols): Process the first symbol of the
2703 static psymbols list.
2704 (types_info): Restore this function from its untimely #if 0.
2705 It's not perfect, but it is better than nothing.
2706 (_initialize_symtab): Restore "info types".
2708 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2710 * m68k-stub.c: Remote stub for 680x0's, created from
2711 rem-m68k.shar (which is removed).
2712 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
2713 Remove RCS log stuff now that we use CVS and it blows our diffs.
2715 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2717 * symmisc.c (free_named_symtab): Make it work, in its current
2718 kludgy fashion. Change result to indicate if we blew away bkpts.
2719 * dbxread.c (end_symtab): Accumulate result from
2720 free_named_symtab and print warning if we blew user's state.
2721 * symfile.h: free_named_symtab now returns an int.
2723 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
2725 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
2726 is the first symbol read, even if not mainline.
2727 (dbx_psymtab_to_symtab): symfile might be zero, cope.
2728 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
2729 (set_section_command): New command ("section xxx yyy" -- should
2730 be renamed to "set section xxx yyy" FIXME) which sets the
2731 base address of a section of the exec file, overriding the
2732 virtual address that BFD reports.
2734 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2736 * exec.c: Add add_syms_addr_command to exec_ops, so you can
2737 load symbols at any address while examining an exec file.
2739 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2741 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
2742 for printing the float info is host-dependent, not
2743 target-dependent. FIXME.
2744 * i386-pinsn.c: Move #includes to top, remove useless ones.
2745 * i386-tdep.c: Don't bother including <.../reg.h> since we
2746 don't use it (and it doesn't exist on host systems).
2748 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
2749 Convert negative numbers properly.
2750 (ieee_test): Make numbers really random; fix format arg.
2752 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
2753 * core.c (core_detach): Unpush core_ops, which might not be on
2754 top. We used to just pop the top, which broke things. Don't
2755 need dont_repeat() any more.
2756 (core_file_command): Psst! Don't repeat it.
2757 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
2758 * expprint.c (print_subexp): Avoid switch fallthru on
2759 BINOP_ASSIGN_MODIFY, so we can print += and such.
2760 * frame.h: Fix typo.
2761 * inflow.c (kill_command): After killing inferior, print our
2762 current frame in the core file, if we have one.
2763 (generic_mourn_inferior): When inferior dies, either select
2764 the current frame (in the new target, e.g. core file), or
2765 set both the current and selected frames to NULL.
2767 Changes from Peter Schauer.
2769 * infptrace.c: Avoid <sys/ptrace.h> on USG.
2771 * Make all file names fit in 14 characters (sigh and damn!):
2772 mv hp300hpux-xdep.c hp300ux-xdep.c
2773 mv symmetry-xdep.c symm-xdep.c
2774 mv symmetry-tdep.c symm-tdep.c
2775 mv convex-opcode.h convx-opcode.h
2776 mv tm-vxworks960.h tm-vx960.h
2777 mv tm-vxworks68.h tm-vx68.h
2778 mv Makefile.srcdir Makefile.sdir
2779 mv gdb-int.texinfo gdbint.texinfo
2780 mv remote-sa.m68k.shar rem-m68k.shar
2781 mv remote-multi.shar rem-multi.shar
2782 * Makefile.dist, README, config.gdb, convex-pinsn.c,
2783 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
2784 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
2787 * command.c (user_info_1, user_info): New command for listing
2788 the user-defined commands.
2790 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2792 * dbxread.c (really_free_pendings): Clear file_symbols
2793 and global_symbols after freeing them; otherwise, running
2794 this function twice (if it appears twice on the cleanup
2795 chain), we try to free things twice.
2797 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
2798 based on text_addr (the address of text in core), not on addr (the
2799 offset between text in the .o file and in core). This change
2800 is from Peter Schauer.
2802 * main.c: Define ALL_CLEANUPS as a cast of zero.
2803 (return_to_top_level): Use it.
2804 (main): Do all cleanups after each command run as part
2805 of the gdb startup sequence. Also do all cleanups before
2806 entering the command loop, and every time we exit the command
2807 loop and reenter. Before, the cleanups from the startup sequence
2808 were being left undone until the first error!
2809 (command_loop): Rename do_nothing cleanup to command_loop_marker
2810 so we can see it easily when examining the cleanup chain.
2811 (init_signals): Add another do_nothing for signal handling.
2812 (quit_command): Only try to kill target if it has execution.
2813 Problems in the target stack got us into a state where
2814 inferior_pid was nonzero but none of the targets had execution.
2815 In this state you couldn't exit gdb.
2817 * dbxread.c: Two changes from Peter Schauer.
2818 (echo_command): Fflush output after an echo command.
2819 (show_history): Pass all args to cmd_show_list.
2821 * utils.c (init_malloc): Call mtrace to turn on tracing
2822 if the environment variable MALLOC_TRACE is set to a file name.
2823 * mtrace.c: Add source file which provides a log of every malloc,
2824 free, and realloc to a trace file.
2825 * mtrace.awk: Add source file which analyzes the trace file.
2826 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
2827 (VERSION): Roll to 3.94.3.
2829 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
2830 (check_duplicates): Don't bother with watchpoints.
2831 (set_raw_breakpoint): Comment about danger of this routine.
2832 (watch_command): Parse and eval all args before calling
2835 * solib.c (find_solib): Avoid error in referencing memory to
2836 see if any more shared libraries have been added. This is
2837 particularly useful if the target has terminated. Bug reported
2840 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
2841 in bringing up 3.94.2 on the Sun-3.
2843 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
2844 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
2845 expression (in scope) before reenabling watchpoint.
2846 * signame.c (init_sigs): Add missing declaration of i, fix
2847 sys_siglist declaration.
2848 * source.c (list_command): Fixed range computation to use
2850 * stack.c (backtrace_command): Do not allow command if target has
2851 no stack, print informative error message.
2852 * target.c (target_command): Do not write into command line
2853 because this fails if the target command is used in a user defined
2854 command. [This change was enhanced by gnu to support any-
2855 unique-prefix matching on target names.]
2856 * valops.c (value_struct_elt): Avoid infinite loop on an
2857 erroneous attempt to print the member of function (try p main.p).
2859 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2861 * expread.y (name_no_typename): Avoid reduce/reduce errors
2862 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
2863 Since the GDB parser really doesn't use name_no_typename in a
2864 name-only context, the parser can't tell the diff between
2865 names and numbers here. Avoid allowing a name_no_typename
2866 to be a NAME_OR_*INT to resolve the conflict.
2868 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2870 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
2872 * valprint.c (val_print_fields): bitfield printing didn't handle
2873 byte order. Indirect through a few more fns to cope.
2875 * values.c (modify_field): also cope with byte order.
2877 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2879 Cleanup for release 3.94.2:
2881 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
2882 include files. Roll version to 3.94.2.
2884 * coffread.c (init_stringtab): Read length into unsigned char
2885 array before swapping; don't assume 32-bit longs.
2887 * target.c (target_info): Don't bother with get_sym_file, just use
2888 the symfile global variable.
2889 * symtab.h, symfile.c (get_sym_file): Delete it.
2891 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
2892 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
2893 (read_type): Replace one more error() with complain().
2895 * mipsread.c (parse_partial_symbols): Replace printf with complain.
2897 * i960-tdep.c: Fix copyright attribution.
2899 * config.gdb: Quote all backquotes in doublequotes. You can
2900 quote me on that. BSD 4.4 shell found this one.
2902 * infptrace.c (throughout): The third argument to ptrace is an
2905 * infrun.c (wait_for_inferior): When program has terminated, we
2906 have to call target_terminal_ours before we pop that target off
2907 the stack (e.g. before a call to target_kill or
2908 target_mourn_inferior). This fixes problem where a program
2909 terminates, then GDB stops for (tty output) and you have to type
2910 "fg" to the shell to resume it. FIXME: This code for what to
2911 do after termination really should be in normal_stop instead.
2913 * gdbcore.h (read_memory_check): Change declaration; it changed
2916 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
2917 4.4 prereleases, this avoids a bug in their sgtty compatability
2919 * remote.c: Use terminal.h rather than hand-rolling the same.
2921 * signame.c, signame.h (psignal): Arg is unsigned, not int.
2922 * utils.c (strsave, strstr): Fix arg types.
2923 * valprint.c (val_print): lint
2925 MIPS symbol table support from Per Bothner:
2927 * symfile.c (symtab_fns): Remove initializer table that needs to
2928 be hacked for each new symbol file format supported.
2929 (add_symtab_fns): New function, chains symbol table
2930 handlers into the global list.
2931 (symfile_init): Search this list.
2932 * symfile.h: Add next pointer, declare add_symtab_fns.
2933 * coffread.c (_initialize_coffread): Call add_symtab_fns.
2934 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
2936 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
2937 symbol *). Thus, we no longer need the hack to trash
2938 pst->filename. Good, since that hack confused code in symfile.c!
2940 (reorder_symtabs, destroy_all_symtabs): Removed static
2941 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
2942 Instead, the latter now uses a temporary array (stack-allocated
2943 from an obstack, and then freed).
2945 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
2946 haven't been set in the outermost stBlock of a procedure. This was
2947 a problem with f77 binaries on Ultrix 4.?.
2949 (new_symtab, new_symbol, new_type): Continue changing code to use
2950 obstacks more and otherwise conform to dbxread internal style.
2951 Made the free_code of symtabs be free_linetable (as in dbxread)
2952 instead of free_contents. This implies memory leaks when reading
2953 a new symbol table, until the conversion is finished. Did change
2954 (struct symbol) and (struct type) to be allocated on the
2955 symbol_obstack. Blocks and blockvectors are among the things
2958 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
2959 tested much, but it solved one problem (reported by Meissner), and
2960 cleans up some other things. The problem happened when an
2961 included file contains actual code (functions) and not just
2962 definitions. The mips coff is a little inconvenient there, since
2963 it may cause a procedure to be mapped to the wrong psymtab.
2965 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
2966 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
2967 this will need work for the new core paradigm.
2969 Opcode patches from the net:
2971 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
2972 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
2973 missing altogether - they are added here. From Bruce Bauman.
2974 * mips-opcode.h: The low mask for C0 instructions was too small.
2975 From Garrett Lau. I modified the fix to check the entire 32-bit
2978 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
2981 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2983 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
2985 * dbxread.c (read_type): Pointer subtraction (value_sub in
2986 valarith.c) sometimes failed because the types of the
2987 pointers being subtracted were not identical.
2988 These differed because dbxread.c was allocating pointer types
2989 using dbx_alloc_type+smash_to_pointer_type instead of
2990 lookup_pointer_type. I failed to find a justification for the
2991 former, so I changed it to use the latter. Similarly, I
2992 replaced smash_to_function_type by lookup_function_type,
2993 and smash_to_reference_type by lookup_reference_type.
2995 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
2996 _initialize_mipsread): corresponding changes.
2998 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3000 * source.c (mod_path): Do tilde_expand on each component of the path,
3001 rather than on the (list of) paths as a whole.
3002 (print_source_lines): Set first_line_listed in addition to
3003 current_source_symtab and current_source_line. If the source was
3004 not findable, after a "dir" command to fix the problem,
3005 a "list" would get the wrong lines.
3007 While I was there... (gnu):
3009 * dbxread.c (read_type): Change error to complaint.
3011 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3013 First attempt at detailed understanding of symbol table memory alloc.
3015 * dbxread.c (dbx_symfile_read): Free our string table if we
3016 aren't the mainline. Free the "info" struct since we're done with
3018 (init_psymbol_list): Free any previously allocated psymbol lists.
3019 (): FIXME: Should realloc-down the psymbol lists when done reading
3020 the main symbol file?
3022 * symmisc.c (free_symtab): Free fullname field too.
3024 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3025 (REGISTER_ADDR): Make result type unsigned int.
3027 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3028 define REGEX must also define REGEX1 (its dependency).
3030 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3032 * tconfig/i960: No longer works, points you at vxworks960 or
3035 * xgdb.c, XGDB-README: Remove file. Users can get the much
3037 * Makefile.dist: Remove all trace of xgdb.
3039 * breakpoint.c (breakpoint_1): Pass demangle arg to
3040 print_address_symbolic.
3041 (clear_breakpoints): Remove unused function.
3042 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3043 (breakpoint_re_set): Use catch_errors to do them all anyway.
3045 * gdb-int.texinfo (Host versus Target): Add section on what is
3046 a "host" feature versus what is a "target" feature.
3048 * infcmd.c (path_command, path_info): Handle the PATH variable
3049 (object search path) as conveniently as the source search path.
3050 * environ.c (set_in_environ): Set some vars in GDB's environment,
3051 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3052 * source.c (mod_path): New function, from guts of
3053 directory_command, modifies a path. Used by path_command.
3054 (directory_command): Call it.
3055 * defs.h (strsave): Declare.
3057 * utils.c (sevenbit_strings): Add new printing option.
3058 (printchar): Use it.
3059 (strsave): Provide this handy helper routine.
3060 (set_width_command): Rename set_screen_width_command.
3061 (_initialize_utils): "set screen-width" => "set width";
3062 "set screen-height" => "set height"; add sevenbit-strings.
3064 * infcmd.c (do_registers_info): Print floating point registers
3065 in raw hex as well as float format, regardless of whether it is
3066 a "virtual" convertible register.
3067 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3068 regs as a double, just in case it's being used that way.
3069 * values.c (unpack_long): Comment on array/function coercion.
3070 (unpack_double): Argument is in target byte order now. For
3071 integer arguments, just call unpack_long and float the result.
3072 * m68k-tdep.c: include defs.h for "const" handling.
3073 * remote-nindy.c: Use ieee-float stuff.
3074 (nindy_fetch_registers): Unpack double regs to host double, then
3076 (nindy_store_registers): Pack extendeds to host double, flip
3077 around by misusing unpack_double, send as target double.
3079 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3080 zero, as when stopped at the first instruction of a process.
3082 * blockframe.c: Fix filename in comment (param.h => tm.h).
3083 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3084 * tm-68k.h: Fix typos.
3086 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3088 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3090 * coredep.c (fetch_core_registers): Pass end-address of register
3091 section to register_addr as expected. Don't call supply_register
3092 if we'd just pass it garbage.
3094 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3096 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3098 * target.c (push_target, target_info): Cast enums to int for < or
3101 * stack.c (print_frame_info): Identify source file & line
3102 even if we can't print it.
3104 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3106 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3108 Clean up IEEE floating point support.
3110 * ieee-float.h: New file.
3111 * ieee-float.c: Write real routines to convert between host
3112 doubles and various target IEEE extendeds.
3113 * m68k-xdep.c: Eliminate assembler code for extended floats.
3114 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
3115 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3116 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3117 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3118 double_to_ieee_extended.
3119 * i960-tdep.c: Define ext_format_i960.
3120 * m68k-tdep.c: Define ext_format_68881.
3121 * sparc-tdep.c: Define ext_format_sparc, though unused.
3122 * Makefile.dist (HFILES): Add ieee-float.h.
3123 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3126 Obsolete the "coffstrip" program in favor of using BFD's strip.
3128 * nindy-share/coffstrip.c: Remove file.
3129 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3130 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3131 * tconfig/nindy960: Remove reference to coffstrip.o.
3133 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3135 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3137 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3138 * dbxread.c: Remove static symfile_bfd.
3139 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3141 * inftarg.c (child_detach): Pop the child_ops vector if the
3142 detach is successful.
3143 * remote-nindy.c (nindy_create_inferior): Don't push a new
3144 nindy_ops since nindy uses the same one for execution and memory
3146 * core.c (core_ops): Use child_attach and child_create_inferior
3147 rather than default attach and create_inferior functions.
3149 Handle floating point registers in core files.
3151 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3152 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3153 This version untested since BFD doesn't yet support sun3 core
3155 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3156 conventions. Fix comments and style. This version has not
3157 been compiled yet, since we have no HP inhouse.
3158 * core.c (get_core_registers): Look for two sections, ".reg"
3159 and ".reg2", and pass both to fetch_core_registers sequentially.
3161 Revise directory path yet again.
3163 * source.c (forget_cached_source_info): Not static any more.
3164 (init_source_path): New default source path is "$cdir:$cwd".
3165 (dir_command): Handle variable arguments ($cdir, $cwd).
3166 (source_info): Print "Compilation directory" rather than
3167 "Originally compiled in" to remind people of $cdir.
3168 (openp): If the path contains $cwd, use current directory.
3169 (open_source_file): If compilation directory is known, replace
3170 first $cdir in path with the compilation directory.
3171 (print_source_lines): Even if we can't print the lines, set the
3172 current symtab and line for future commands like "info source" or
3173 "breakpoint". Also, error message now contains the file name,
3174 line number, and file access error message.
3175 (_initialize_source): Fix help text to describe changes.
3176 * main.c (cd_command): Forget cached source info when we chdir.
3177 * utils.c (strstr): Add simple implementation.
3179 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3181 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3182 Byte-swap COFF symbol tables if necessary when reading them in.
3183 Use complain() to replace error message in one spot. Needs
3184 corresponding change in bfd/coff-code.h to make some symbol
3185 swapping routines non-static.
3187 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3189 Merge changes from Eirik Fuller, for UTek.

3192 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
3193 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3194 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3195 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
3196 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
3197 declarations of errno.
3199 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3201 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3202 <rpc/rpc.h> and <rpc/types.h>.
3204 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3206 * i960-tdep.c (examine_prologue): Add new argument limit,
3207 which stops the scan at the end of the prologue, or at the PC.
3208 This fixes a problem where it walks down into the code for the
3209 user's statements if that code looks like function prologues.
3210 Mark Fox and I have been bouncing this code back and forth, making
3211 small changes to it. Callers changed to match.
3213 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3215 Cleanup for gdb-3.94 release final:
3217 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3218 the .c files from vx-share and nindy-share, from the various
3219 macros, since they are not found via ALLDEPFILES.
3220 (SFILES): Add tm-i960.h.
3221 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3222 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3224 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3225 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.

3229 * am29k-tdep.c: Add contribution line.
3230 (examine_prologue): Cache information about function prologues in
3231 the misc-function-vector to avoid lots of references over the
3232 serial line while examining instructions.
3234 * core.c (core_close): New function made from cleanup_core.
3236 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3237 remote-vx.c, remote.c, target.c, target.h,
3238 Update target_ops vector to add attach, close, and load entries.
3239 Use add_syms_addr_command, not add_file_addr_command, for
3240 add_file. Break out close routine from existing code.
3242 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3243 they are in an obstack.
3244 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3246 (define_symbol): Add symbol type parameter; change callers;
3247 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3248 it to influence the symbol class on the i960.
3249 (define_symbol): Swap LOC_CONST's into target byte order.
3251 * exec.c (exec_close): New function.
3252 (exec_file_command): Call it.
3254 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3255 Fix byte order of frame pointer.
3256 (read_var_value): Result of 0 if var's value can't be found,
3257 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3258 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3259 (locate_var_value): Use read_var_value and use its lazy address
3260 as the location of the var's value. Lint.
3262 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3265 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3266 obsolete Intel versions in favor of vxgdb versions.
3267 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3268 code dealing with byte order of values, which Intel did in host byte
3269 order rather than gdb-4's target byte order.
3270 (i960_frame_chain_valid): Move to nindy-tdep.c.
3271 (examine_prologue, skip_prologue, frame_find_saved_regs,
3272 frame_args_address, leafproc_return, saved_pc_after_call,
3273 pop_frame): Add vxgdb versions from Mark Fox.
3274 (examine_prologue, frame_struct_result_address): Add code
3275 to deal with the saved value of G13 (struct return address
3277 (frame_args_address): Modify Mark's version to prefer the
3278 saved value over the current value in the topmost frame.
3279 Cache result in the frame info to avoid performance hair in
3281 (print_fault): Add gdb960 code for printing faults.
3282 (_initialize_i960): Actually call check_host.
3284 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3285 add stub routines. FIXME, these currently just return zero!
3287 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3288 (attach_command): Call target_attach, not target_open, now.
3290 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3291 (child_attach): Rename from child_open.
3292 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3293 don't confuse it with a zero step_resume_break_address.
3295 * inftarg.c (child_detach): Eliminate inferior_pid test.
3296 (child_files_info): Clean up message a bit.
3297 (child_ops): Use child_attach, not child_open, to attach.
3299 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3300 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3301 findvar.c to here, since it depends on the contents of the
3302 shadow_contents of breakpoints, but keep if #if 0 since it is
3305 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3308 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3309 (ptype_command, display_command): Eliminate have_inferior_p and
3310 have_core_file_p in favor of target_has_stack or
3311 target_has_execution.
3312 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3313 code for actually finding the values of arguments, though we still
3314 keep track of the maximum stack offset for use in printing unnamed
3315 arguments. Handle missing FRAME_ARGS_ADDRESS.
3317 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3318 (struct nindy_regs): Define registers passed to/from nindy.
3319 (nindy_fetch_registers, nindy_store-registers): Translate between
3320 nindy and GDB formats for the registers.
3321 (dcache_init): Statically allocate the cache, since it was being
3322 allocated by a malloc that was never freed anyway.
3323 (nindy_create_inferior): Error, not core dump, if no exec file.
3324 (nindy_before_main_loop): Use target_load, not target_add_file.
3326 * remote-vx.c (net_load): Specify large timeout for load
3327 requests. Allow user to break out with INTERRUPT.
3328 (net_break): Remove useless code, clean up. Change callers.
3329 (parse-args, skip_white_space, find_white_space): Clean up arg
3330 parsing to cope with quoted strings.
3331 (net_wait, net_quit): Never call error, just return status.
3332 (vx_read_register, vx_write_register): Cleanup status checking.
3333 #ifdef the code based on which CPU we are using (960 or 68k),
3334 FIXME, this should be completely general but it isn't yet.
3335 (vx_xfer_memory, vx_resume): Cleanup status checking.
3336 (vx_run_files_info): Improve message.
3337 (vx_load_command): Renamed from vx_add_file_command. Allow load
3339 (net_ptrace): Remove unused routine.
3340 (vx_wait): Adopt code from vxgdb960 to cope with broken
3341 connections to target machine and prompt to disconnect. Remove
3342 debug printouts. Map some EVENT_'s to SIGnals.
3343 (add_symbol_stub, vx_open): Print names of object files we found,
3344 and "ok" if we read their symbols OK. Clarify output in general.
3345 (vx_attach, vx_detach, vx_kill): Add these commands.
3346 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3347 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3348 "info files" output, and create_inferior, since we already have
3351 * stack.c (frame_info): Replace Frame_unknown with 0.
3352 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3353 (return_command): Pop until the PC matches as well as the FP,
3354 so it works even if the FP is shared with another function,
3355 as in "frameless" or "leaf" procedures.
3357 * symfile.c (load_command): renamed from add_file_target_command.
3358 (add_syms_addr_command): renamed from add_file_addr_command.
3359 (add_syms_command): Stub to call target_add_syms.
3360 (_initialize_symfile): Change command names and descriptions,
3361 add-file => add-syms, and load from alias to its own command.
3363 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3364 maybe_kill_then_create_inferior): Default for attempts to start
3365 a process, if one is already running, is to ask about killing
3366 it and retry if yes.
3367 (upstack_create_inferior): #if-0 it, strata obsolete it.
3368 (push_target, unpush_target, pop_target): to_close() a target
3369 before unstacking it.
3370 (target_info): Renamed from target_files_info.
3371 (_initialize_targets): Rename "i files" as "i target", accessible
3374 * target.h: Improve comments about the target_ vectored routines.
3376 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3377 Convert commenting style to standard GNU style.
3378 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3379 (SKIP_PROLOGUE): No longer a no-op.
3380 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3381 (*_REGNUM): Sort register numbers.
3382 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3383 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3384 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3385 are now 10 byte extendeds, not 8 byte doubles.
3386 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3387 for nindy versus vxworks targets. FIXME, this should possibly go
3388 in the target vector.
3389 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3390 frame_saved_regs and arg pointer with each frame.
3391 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3392 (FRAME_ARGS_ADDRESS): Use cached result.
3393 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3394 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3395 (PRINT_RAMDON_SIGNAL): Call print_fault.
3396 (POP_FRAME): Now works.
3398 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3399 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3400 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3401 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3404 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3405 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3407 * valarith.c (value_subscripted_rvalue): Avoid handling
3408 floats and doubles specially; it gave alignment errors. Lint.
3410 * valops.c (value_of_variable, value_of_this): Error if unknown
3413 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3414 to avoid alignment problems.
3415 (value_print): Handle unknown value address.
3416 (cplus_val_print): Two args are ignored; remove them. Change caller.
3417 (val_print): Use unpack_long rather than pointer-deref.
3420 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3421 to avoid alignment problems.
3422 (value_being_returned): Error if return value unknown.
3423 (set_return_value): Add bogosity warning, FIXME. *
3425 * TODO: A woman's work is never done.
3427 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3428 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3429 Add ieee-float.o to OBS.
3430 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3431 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3432 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3434 Changes to generalize the VxWorks RPC protocol slightly, to handle
3435 i960 as well as 68000.
3437 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3438 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3439 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3440 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3441 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3442 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3443 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3444 so they will move in target byte order rather than network
3445 byte order (happens to be the same).
3447 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3449 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3451 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3454 Add contribution lines to various files, showing where they
3457 * breakpoint.c (break_insn, check_break_insn_size,
3458 read_memory_nobpt): Remove to mem-break.c.
3460 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3463 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3464 entry has bad register number. This change is not
3465 tested in this release, FIXME.
3467 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3470 * value.h: Force value's contents field to be aligned to hold
3471 at least a double or a long long (if supported). This avoids
3472 doing bcopy's in and out of the contents field.
3474 (step_1): Avoid coredump under obscure circumstances when we
3477 * symtab.h (misc_info): Add field to misc function vector for
3478 any kind of cached information the target code desires. AMD
3479 29000 uses this to avoid repeating examine_function_prologue's.
3481 * coffread.c: Lint. Remove static symfile, read_section_header.
3482 core.c (have_core_file_p): Lint: remove.
3483 expprint.c (print_subexp): Lint.
3484 infptrace.c, valops.c, valprint.c: lint.
3486 Roll in changes from vxgdb-5.0.1:
3488 * symtab.h: Comment byte order of each address class. Add
3489 LOC_LOCAL_ARG for frame-relative args (960).
3490 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3491 symtab.c, symmisc.c: ditto.
3493 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3495 * remote.c (remote_resume): Error if resume with a signal.
3497 * symfile.c (prim_record_misc_function): Clear misc_info.
3498 (fill_in_vptr_fieldno): Check stub type of arg.
3500 * valops.c (value_cast): Avoid looking up names of types whose
3501 name we don't know, to prevent coredump. Sun CC produces typedef
3502 rtx and the name of *rtx is zero...
3504 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3506 Roll in changes from final AMD 29000 port (Tiemann).
3508 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3509 for ../include/a.out.encap.h. This might not work now that BFD
3510 is separately compiled. Instead, BFD support for encap will have
3511 to translate machine type 29k into the right COFF_MAGIC.
3513 * infcmd.c: Remove references to inferior_pid that aren't used
3514 in actual ptrace calls; use target_has_execution, etc.
3515 (have_inferior_p): Remove function.
3516 (program_info): Print target info rather than "process number";
3517 avoid gratuitous messages unless from_tty.
3518 (run_stack_dummy, finish_command): Set proceed_to_finish.
3519 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3520 main.c: Lint. Lose have_inferior_p().
3521 inferior.h (have_inferior_p): Remove, lint.
3522 (proceed_to_finish): Add flag to ask that all regs be saved
3523 by normal_stop, for the few commands that need it, speeding up
3524 serial I/O. Add comments to stop_registers.
3526 * remote-eb.c: Remove newline from breakpoint message we grep
3527 for. Never time out when running the user program.
3531 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3533 Roll in changes from vxgdb-5.0.1:
3535 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3536 symbol in its raw form, we are processing an unlinked ".o" file.
3537 See if the target environment has assigned it an address, using
3538 target_lookup_symbol (VxWorks does), and enter it into the symtab
3541 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3542 68k versions for a simpler version that assumes zero FP at bottom.
3543 Fixes bug of truncated stack reports.
3545 * target.h (target_lookup_symbol): Define this routine's args
3546 and result, finally.
3548 * target.c (nosymbol): Default routine for target_lookup_symbol.
3549 (target_default): Default lookup_symbol and call_function too.
3550 (files_info): Only print has_all_memory warning if a non-dummy
3553 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3554 vx_convert_from_virtual): If target does not have floating point,
3555 zero register "values", and avoid doing cross-net conversions.
3556 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3557 (vx_open): Rearrange code that attaches to target and reads
3558 symbols for all loaded modules, to work if some of the modules
3559 are not accessible. Add symbol_stub() and add_symbol_stub()
3560 as callbacks from catch_errors(). Allow connect attempt to be
3561 interrupted painlessly with ^C (FIXME, there are still some bugs
3562 if the interrupt happens during symbol reading.). Print
3563 final message with puts_filtered, since symbol messages are
3568 * main.c (catch_errors): Only print errstring if non-null.
3569 (command_loop): Avoid an ioctl per command to test ISATTY.
3571 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3572 (vx_xfer_memory): Return correct result!
3573 (vx_files_info): Indicate whether target has float or not.
3574 (vx_lookup_symbol): Complain, not error, if target gone.
3575 (vx_open): Print "Connected" msg before disabling immediate-quit.
3576 [FIXME: lookup_symbol and vx_open changes need testing.]
3578 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3579 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3580 contributor lines and update copyrights to 1991.
3582 Changes from an attempted H-PUX host port:
3584 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3585 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3586 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3587 * remote-vx.c: include <sys/time.h> for HPUX.
3588 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3589 "core_file_command" routine to BFD regime. May not work yet.
3591 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3593 * xgdb.c: Replace X10 version with some VJ version.
3594 (FIXME: Its copyright assignment is not on record.)
3595 * xgdb.c: Update include files to X11R4 (Xaw crud).
3596 (xgdb_display_source, create_text_widget): fix call to
3597 get_filename_and_charpos. Rewack source window stuff for X11R4
3598 (gleaned from include files, and "nm's" of binary libraries, since
3599 I had no doc available).
3600 (append_selection, append_selection_word): Disable with FIXME
3601 since R4 changed interface here.
3602 (create_buttons): Add back the old set of buttons.
3603 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3605 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3606 Roll VERSION to 3.94 (not yet final though).
3608 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3610 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3611 obstack_int_grow, obstack_int_grow_fast): Eliminate
3612 cast on left of assignment, which gives MIPS cc fits and is
3615 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3616 F_ALIAS. Use printf, not fprintf, when not passing a file
3618 (compare_opcodes): Check that identical instructions have
3619 identical opcodes, complain otherwise.
3621 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3622 was reported by Roland McGrath.
3623 (unimp): Only match if exactly zero instruction. (Roland)
3624 (branches and traps): Generate all variations of these
3625 instructions with macros, based on a single call that defines
3626 each condition name and its binary representation.
3627 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3629 * valprint.c (val_print_fields): Take, and use, format parameter.
3630 This means that "p/x struct" again prints the elements in the
3631 desired format. Changed callers.
3633 * stack.c (frame_info): Use filtered output, and indicate wrap
3634 points. Remove kludgy formatting designed to avoid line wrap.
3636 * utils.c (wrap_here): If the line is already full (because
3637 we had printed a long indent or long wrapped string), do an
3638 immediate newline-and-indent.
3640 * m68k-pinsn.c (print_insn_arg): Bugfix from
3641 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3642 instruction is incorrectly disassembled as bkpt #8.
3644 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3645 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3646 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3647 and then will dump core (sometimes). I traced it back to an
3648 uninitialized symfile_name in psymtab_to_symtab.
3649 (const_vol_complaint): Add quotes to message.
3650 (define_symbol): Only believe line number if gcc_compiled.
3651 Avoid allocating symbol if we will not return it.
3653 Add target strata support so that newly established targets go
3654 into their right place in the target stack (e.g. a new exec file
3655 doesn't wipe out the ability to access the running process).
3657 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3658 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3659 and initialize it properly in all the targets.
3661 * target.h: Document strata. Change return type of push_target.
3663 * target.c (nomemory): new function for dummy memory access.
3664 (tcomplain): Rename complain, now also used in symfile.c.
3665 (push_target): Push targets within strata. New return value shows
3666 whether new target is on top of stack or not. Always keep dummy
3668 (target_files_info): Ignore dummy target.
3670 * core.c (core_open): Warn user, and skip accessing file, if the
3671 core target is not the topmost target in the stack.
3672 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3675 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3676 target_ops, it doesn't belong there since we have no regs there.
3677 Change name of target from machine => memory to clarify.
3679 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3681 * Freeze version 3.93 for release.
3683 * Makefile.dist: Handle vx-share and nindy-share subdirs
3684 properly when building gdb.tar.Z.
3686 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3687 printed in various places, so I could change just one copy.
3689 * dbxread.c, coffread.c: Change references to bfd->iostream
3690 to cast to FILE *, now that BFD avoids needing types defined
3691 in other header files.
3693 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3695 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3696 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3697 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3698 (actually gcc -Wall).
3700 * dbxread.c: Remove first_global_sym, last_global_sym, since
3701 they are never referenced.
3703 * defs.h (baud_rate): Declare.
3704 main.c: Define it, and add the -b option to set it.
3706 * gdb-int.texinfo: Add text on how to define a new host or target
3707 architecture, prompted by Per Bothner's questions about MIPS
3710 * gdb.texinfo: Document "complaints". Change doc of -q since
3711 gdb no longer prints the copyright and blurb if you specify a file
3712 name to be debugged (just like Emacs). Add doc for Nindy-specific
3713 command line flags for specifying target serial port and such.
3714 Update copyright to 1991.
3716 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3717 has taken over for us the job of ripping up executable files. The
3718 crud caused Per Bothner's port to not compile.
3720 * infrun.c (normal_stop): Avoid printing "Program exited
3721 normally" if we are in batch mode. This allows a GDB which
3722 executes a program on a target system, to behave like a Unix
3723 command (input from stdin, output to stdout, no extraneous
3726 * main.c (main): Allow additional machine-dependent command line
3727 options to be specified with the ADDITIONAL_OPTIONS,
3728 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3729 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3730 processing to occur just before the main loop with
3731 BEFORE_MAIN_LOOP_HOOK.
3732 (main): If a "core file" argument is specified, and it is not a
3733 core file, try it as a process ID to attach.
3734 (symbol_completion_function): Attempt to cope with
3735 "show screen-" TAB, not very successfully. This needs more work,
3737 (batch_file): New function, returns whether we are reading
3738 commands from an interactive tty on stdin, or from somewhere else.
3739 Called by normal_stop since it doesn't get from_tty passed down
3740 to it like many commands do.
3742 * remote-nindy.c: Handle command line options for nindy
3744 (nindy_before_main_loop): Prompt user for tty name if they
3745 don't specify it before getting to the interactive command loop.
3747 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3748 and -r command line options. Also add hook before main loop
3749 to make it easy to specify a tty.
3751 * TODO: More things to do, one done.
3753 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3755 * dbxread.c: Make complaint() calls pass pointer, not struct.
3756 Add complaints about badly formatted C++ type information
3757 (const/volatile indicator, and parse errors resulting in
3758 error_type). Fix C++ virtual member fn comment.
3759 (read_struct_type): Avoid bumping pointer if we got a parse
3760 error; this prevents our walking beyond the end of a string.
3761 Terminate loop on null char as well as semicolon.
3762 (process_one_symbol): Fix the LBRAC fix so that it uses the
3763 last previous SLINE, FUN, or SO record's PC address. C++ debug
3764 symbols did not have SLINE records in a useful order compared
3765 to the LBRAC records.
3766 (define_symbol): Handle "catch" records.
3768 * symtab.c (check_stub_type): Added new complain
3769 `stub_noname_complain' and added a consistency check to
3770 keep the debugger from crashing when finishing from an
3771 exception frame. A real fix will be needed later.
3773 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3775 * infcmd.c (attach_command): Make global.
3777 * Makefile.dist (REMOTE_OBS): Make these compile by default,
3778 but make them easy to comment out. Perhaps later they should
3779 be enabled by what CPU you configure for? FIXME.
3780 (VERSION): Roll to 3.93.
3781 (pinsn.o): Remove rule for obsolete file.
3782 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
3784 Run down a problem that manifested by printing the wrong function
3785 name in stack traces of read_ofile_symtab. Turned out that the
3786 problem was the SunOS 4.1.1 (and previous) C compiler outputs
3787 the LBRAC symbol with an address in the *data* segment, which
3788 blew our binary search through the blocks.
3790 * dbxread.c: Use the complain() facility consistently to bitch
3791 about problems in the symbol file we are reading.
3792 (finish_block): Add code to check the nesting of the blocks;
3793 complain and Procrust them to fit if wrong.
3794 (make_blockvector): Check the order of the blocks, complain
3795 [but don't cope] if wrong.
3796 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
3797 symbols to be sure their PC value is greater than the last SLINE
3798 (line number) symbol we've seen, complaining and adopting the
3799 SLINE PC value if wrong.
3801 * symfile.h (struct complaint, complaint_root, complain,
3802 clear_complaints): Add.
3803 * symfile.c (complain, complaint_root, clear_complaints): Add
3804 facility to deal with non-fatal complaints and to regularize their
3806 (symbol_file_add): Clear complaint counters to allow new complaints.
3807 (initialize_symfile): Add 'set complaints' and 'show complaints'.
3809 * dbxread.c (dbx_symfile_read): Remember the address and size
3810 of the string table for the main symbol file, so we won't read it
3812 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
3813 to avoid reading the string table yet again. Lint.
3814 (throughout): Improve filtered output, including word wrap.
3815 (read_range_type): Improve Bothner's fix to handle other types too.
3817 * utils.c: Improve line wrap implementation. Handle unlimited
3818 width by making chars_per_line unsigned.
3819 (puts_filtered): New, easy, function.
3821 * defs.h (puts_filtered): add.
3823 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
3824 call the identical sort_symtab_syms() in symfile.c instead.
3826 * expread.y: Suggest the `file' command rather than `symbol-file'.
3828 * command.h (enum var_types): Add zinteger for seroable
3830 * command.c (do_setshow_command): Handle var_zinteger. Restructure
3831 nested if's into a switch.
3833 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
3834 we did not stop because of a breakpoint (it must have been for
3835 some other reason, like a "stepi"), so don't print anything.
3837 * symtab.c: Include <sys/types.h> all the time. Now that BFD
3838 doesn't include <sys/types.h>, old SunOS's require it for
3841 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
3843 A test port of gdb-3.92.6 to the Sony NEWS.
3846 Don't normally link in remote- or vx stuff.
3847 Some of it doesn't compile, and it wastes space for 99% of the users.
3848 Remove reference to no-longer-used HAVE_VPRINTF.
3849 Fixed BFD_DEP typo to BFD_DIR.
3851 Fix cast in arg to bfd_h_getlong.
3852 Make char *prefix be const.
3853 Fix how certain range types are mapped into builtin unsigned int types.
3855 Remove 2 #includes. They cause errors (on Sony, at least),
3856 and aren't needed (they wern't in earlier versions).
3858 print_address_symbolic should never demangle labels
3859 (since it prints *assembler-level* labels).
3861 [This was superseded by the change to printcmd below.]
3864 Add some "volatile" return types to avoid warnings.
3865 If MISSING_VPRINTF add vprintf function and not just macro
3866 (since vprintf is used in printcmd.c).
3868 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
3869 (The latter isn't grokked by some PCC-based compilers.)
3871 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
3873 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
3874 * nindy-share/coffstrip.c
3875 Added some forward declarations (otherwise, gcc complains
3876 about implicit extern redefined as static).
3878 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3880 Changes inspired by Per Bothner:
3881 * printcmd.c (print_address_symbolic): Take additional parameter
3882 specifying whether to demangle.
3883 (print_address): Pass in asm_demangle to control demangling.
3884 (print_address_demangle): New fn, takes explicit arg to control
3886 * utils.c: Add new vars demangle and asm_demangle, and let them
3888 (fputs_demangled): If !demangle, just print the argument.
3889 (fprint_symbol): If !demangle, just print raw symbol.
3890 * valprint.c (val_print): Call print_address_demangle rather than
3891 print_address, to cause demangling to depend on the global
3892 rather than assembler-level demangling setting.
3893 * WHATS.NEW, gdb.texinfo: Document.
3895 * main.c (show_command): Show all settings if no arg.
3896 (initialize_main): Make "info set" the same as naked "show".
3897 * command.c (cmd_show_list): Handle prefix commands in the
3898 list, and print the name of the setting as well as its English
3899 description and value.
3901 Allow gdb functions to specify where a line should wrap if it
3902 exceeds the size of a terminal line. Use it to make the output
3904 * utils.c (set_screen_width_command): New fn, mallocs a buffer
3905 of the right size when screen width changes.
3906 (set_screensize_command, screensize_info): Remove #if 0'd fns.
3907 (wrap_here): New fn, indicates a point in the output where we
3908 should wrap the line rather than just letting it overflow at a
3910 (fputs_filtered): Implement wrapping.
3911 (n_spaces): New fn, returns a pointer to N spaces.
3912 (print_spaces_filtered): Use n_spaces.
3913 * defs.h (n_spaces): Declare.
3914 * stack.c (print_frame_info): Wrap with 4-space indent after
3915 fn name and before filename and line number.
3916 * printcmd.c (print_frame_args): Wrap with 4-space indent
3917 before each argument name is printed.
3918 * valprint.c (value_print): Wrap with no indentation before
3920 (val_print_fields): Wrap with indentation relative to nesting
3921 level before each field name.
3922 (val_print): Wrap with nesting indentation before array elements.
3923 * command.c (do_setshow_command): Avoid extra newlines,
3924 wrap with 4-space indent around values printed, end with period.
3925 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
3927 * breakpoint.c (breakpoint_1): Implement addressprint for
3928 "info breakpoints" display. Change file name and line number
3929 format to " at file:nnn" rather than " (file line nnn)".
3930 * gdb.texinfo: Document.
3933 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3935 Frozen for gdb-3.92.6 release.
3937 README, WHATS.NEW: Update for 3.92.6 release.
3939 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
3940 coffread.o from configs since it is now built by default.
3941 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
3942 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
3943 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
3944 from configs since it is now built by default.
3946 Makefile.dist: Update for release 3.92.6. Handle files that
3947 have been moved to ../include, ../getopt, or ../bfd. Add
3948 saber.suppress and tests directory. Add config.status to
3949 the release (it will say "none").
3951 coredep.c: Minor formatting fixes.
3953 These changes were made in early December but only checked in now:
3954 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
3955 nindy-share/nindy.c: lint
3956 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
3957 register values coming back from the target; we store values
3958 in target byte order everywhere.
3960 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
3962 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
3964 * valprint.c (cplus_val_print, val_print_fields): New functions,
3965 which print C++ objects. They conspire to avoid printing a
3966 virtual base class more than once, following all the twists and
3967 turns of C++ virtual base rules.
3968 (val_print): Call the above rather than do it by hand.
3970 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
3971 symbol file, not for added files like shared libs. This really
3972 needs to be generalized to a timestamp per file.
3974 * core.c (cleanup_core): Avoid coredump if no core file.
3976 * config.gdb: Accept -host or -target in place of +host or
3979 * coffread.c (find_linenos): Avoid desupported BFD interface
3980 to line numbers. We still read them manually rather than using
3981 BFD's "generic" features.
3983 * gdbrc.tex, threecol.tex: Add GDB reference card and its
3985 Makefile.dist: Add refcard to OTHERS list for creating tar files.
3987 * Makefile.dist: Eliminate use of $< in explicit targets.
3989 * readline/Makefile: Use $< rather than $*.c, which does not
3990 include the VPATH in GNU Make.
3992 * tconfig/i960-bout, tconfig/i960-coff: These are identical
3993 copies of tconfig/i960, added for global configuration
3994 compatability. All i960 versions can read both coff and b.out.
3996 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
3997 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4000 * TODO: Think of more things to do.
4002 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4004 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4005 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4006 64-bit float conversion.
4008 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4009 equivalent to sun?os4 so global config works.
4011 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4013 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4015 * main.c: Only declare linesize once; declare pagesize not at
4016 all, since it is never used.
4017 (main): Clear newly allocated line before it is used.
4019 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4021 Further stabilization for the Intel 960.
4023 * Makefile.dist: Parameterize the location of the "include"
4024 and "bfd" directories, as well as "getopt". Add symfile.c.
4025 Link in both dbxread and coffread. Fix up "make depend" to
4026 rewack the locations of include, bfd, and getopt in its output.
4028 * README: Document moving include files, improve some of
4031 * coffread.c: Move common code out to symfile.c. Change
4032 symbol_file_command style interface to use new *_symfile_init
4033 and *_symfile_read interface under BFD. Use BFD internal
4034 info to locate line table, symbols, etc.
4036 * core.c (core_fetch_registers): Rename to get_core_registers
4037 to avoid confusion with fetch_core_registers.
4038 (register_addr): Move to coredep.c, which is already machine
4039 dependent. This leaves core.c pretty clean of dependencies.
4041 * coredep.c (register_addr): Accept this routine from core.c.
4043 * dbxread.c: Move common code (with coffread.c, etc) into new
4044 symfile.c. Each psymtab now contains a pointer to the
4045 format-dependent function that knows how to read it in. Make
4047 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4048 (process_one_symbol): Add code to complain about a "compiler bug
4049 we muzzle here", if we actually see it.
4051 * eval.c (evaluate_subexp): Insert missing "break" statements
4052 in code that determines whether a variable is an lvalue in
4053 memory, register, or whatever. I detected this via a compiler
4054 bug in which it *almost* mashed out the whole switch statement.
4056 * gdb-int.texinfo: Add minor sections on configuring gdb for
4057 release, and about the README file.
4059 * infcmd.c (registers_info): Fix formatting somewhat. Still
4060 not as pretty as before, but it handles byte swapping.
4062 * remote-nindy.c: If data cache routines are interrupted while
4063 waiting for the remote end, be sure that any uninitialized cache
4064 blocks are on the free list, not on the valid list!
4066 * symfile.h: Flesh out this header file with all the various
4067 routines and variables that have been merged in from dbxread.c
4068 coffread.c, and symtab.c to symfile.c.
4070 * symfile.c: New file, containing code common to dbxread.c,
4071 coffread.c, and some code from symtab.c. All generic code for
4072 reading symbol files should be in here now.
4073 (unrecord_misc_function): Remove unused function.
4075 * symtab.h: Remove file-reading things to symfile.h.
4077 * symtab.c: Remove file-reading things to symfile.c.
4079 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4080 to decode i960 fault types.
4082 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4083 target.c: Change type of the "resume" function from int to void,
4084 since its result was never used.
4086 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4088 * main.c: Replace "stupid" with "caution"; you now "set caution
4091 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4093 * infcmd.c (do_registers_info): Call val_print to deal with the
4094 byte order of the registers being printed. FIXME, this makes
4095 the formatting of the output uglier.
4097 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4098 defined, call it for signals the debugger doesn't itself use.
4099 The i960 uses this for more detailed fault information.
4101 * remote.c (remote_open): If arg is null, print help rather than
4104 * sparc-xdep.c (register_valid): Avoid declaring size, since
4105 various modules will think of various sizes depending on the
4106 architecture of their tm-file. FIXME, we need protection against
4107 actually entering one of those modules, which would clobber
4108 storage if not for the target architecture compiled into gdb.
4110 * stack.c (up_command, down_command): Always print the frame
4112 (up_silently_command, down_silently_command): New commands
4115 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4117 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4118 more parameters than it used to.
4120 * findvar.c (registers): Increase slop to 256 bytes, which should
4121 protect us against even most RISC machines with large register
4123 (locate_var_value): Move declaration inside related ifdef.
4125 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4126 throughout, to avoid throwing away buffered input from the board.
4127 (nindy_wait): Supply_register takes addr_of_value, not value.
4128 (i960_print_fault): Renamed from i80960_fault.
4129 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4130 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4132 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4133 we can set the PC in the call to proceed(). Unpush nindy_ops
4134 before pushing it on top, to avoid message to user. Eliminate
4135 commentary from Unix machines that just misleads here.
4136 (reset_command): Fix error message to suggest target command.
4138 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4140 Release 3.92.5 as frozen.
4142 Stabilize the merged release...with help from lint, Saber C,
4145 Everywhere: Add include files needed to declare return types
4146 of functions called.
4148 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4150 * breakpoint.h: Add undeclared breakpoint functions, and some
4151 functions for display handling since I couldn't think of a better
4154 * breakpoint.c (insert_breakpoints): Make code for disabling
4155 shared library bkpts more likely to work. It's used when we
4156 rerun a program and stop before the shared library has been
4158 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4159 cast from pointer, so it squeezes through catch_errors.
4160 (bpstat_stop_status): Fix logic broken some time ago. We now
4161 always create a bpstat if the stop address matches a breakpoint,
4162 even if we don't stop there -- just like the old code used to do
4163 before I got my fingers into it (sigh).
4164 (breakpoint_1): Print "ignore count" after "stop only if"
4165 condition, since that's how it actually works.
4166 (mention): Handle watchpoints as well as breakpoints.
4167 (watch_command): use set_raw_breakpoint and mention to do most
4168 of the work (and initialize all the fields!). Only pass one
4169 arg to parse_c_expression, since that's all it takes.
4171 * command.c (not_just_help_class_command): Rename arg to args
4172 since we ignore "unused argument" warnings on vars named "args".
4173 inflow.c (child_terminal_info): ditto.
4174 infptrace.c (kill_inferior): ditto
4175 main.c (catch_errors, version_info, quit_command, pwd_command,
4176 source_command, dump_me_command, editing_info,
4177 set_history_size_command, set_history, show_history,
4179 stack.c (locals_info): ditto
4180 target.c (target_files_info): ditto
4181 valprint.c (set_input_radix, set_output_radix): ditto
4183 * core.c: Remove old variables for handling core and exec file
4184 sections (data_start, data_end, stack_start, stack_end,
4185 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4186 text_end, exec_data_start, exec_data_end, text_offset,
4187 exec_data_offset, data_offset, stack_offset). They're
4188 superseded the more general build_section_table and
4190 (get_exec_file): Mention the `file' command.
4191 (read_memory_check): Rename to memory_error, and only call it
4192 in the case of an actual error.
4193 (read_memory, write_memory): call memory_error.
4194 (core_fetch_registers): Register section name is ".reg".
4196 coredep.c: Remove a bunch of crud now that all this file does
4197 is pull the registers out of a core file.
4198 (fetch_core_registers): Rewrite to actually work, I hope.
4200 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4201 Replace index() with strchr(). Remove all the pre-BFD macro
4202 definitions for accessing the symbol file.
4203 (struct dbx_symfile_info): Encapsulate the information that
4204 dbx_symfile_init needs to pass to dbx_symfile_read in this
4207 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4208 dbx_symfile_discard): Rearrange symbol file reading to divide
4209 the format-specific part from the format-independent part,
4210 leaving the format-independent part such as file name expansion
4211 and opening in symtab.c. This replaces
4212 partial_symbol_file_open and partial_symbol_file_read.
4213 Symbol_file_read, add_file, add_file_target_command,
4214 add_file_addr_command move to symtab.c. Pass an explicit
4215 "mainline" flag for when reading the main symbol table, rather
4216 than relying on the offset address to be zero or nonzero.
4218 (dbx_symfile_read): Don't allow void *'s to be printed as
4220 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4221 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4222 macro" debug version really work.
4223 (read_dbx_symtab): Remove unref'd parameter inclink.
4224 Avoid swapping N_SLINE symbols, for speed.
4225 Merge N_TEXT!N_EXT case with the other external symbol
4226 definitions' case. Add comments.
4227 (start_psymtab): Allocate the symfile name in the psymtab on
4228 the psymbol_obstack, rather than using the caller's storage.
4229 (end_psymtab): Only allocate a dependencies list if there are
4231 (psymtab_to_symtab_2): Use BFD when reopening file to read
4232 its symbols for real.
4233 (read_struct_type): Add FIXME comments where it needs work
4235 (read_huge_number): Add FIXME about overflows.
4236 (read_range_type): Add FIXME about comparing a long to 1<<32.
4238 * coffread.c: Minor changes to move things closer to the new
4239 regime with symtab.c and dbxread.c Major work is still needed
4242 * exec.c (exec_file_command): Remove old variables (see core.c
4244 (xfer_memory): If memory transfer is right at the end of a
4245 section, don't lose.
4247 * findvar.c (get_saved_register): If value is in a real
4248 register, LVAL is lval_register, not lval_memory.
4250 frame.h: Declare print_sel_frame and record_selected_frame.
4252 gdb-int.texinfo: New file, for GDB internals documentation.
4253 Very simple, unformatted doc of cleanups is there for now.
4255 gdbcore.h: Remove obsolete variables that described a.out
4256 section addresses and offsets. (See core.c above.)
4257 Declare fetch_core_registers and registers_fetched.
4259 getopt.c: Declare char *alloca(); even on SPARC.
4261 infcmd.c (run_command): Call target_kill rather than
4263 (step_command, next_command, stepi_command, nexti_command):
4264 Declare from_tty parameter even though we don't use it.
4265 (run_stack_dummy): argument BUFFER is a char array, not
4266 a pointer to REGISTER_TYPE.
4267 (finish_command): using_struct_return needed a value *,
4268 not a struct symbol *.
4270 * infptrace.c (child_xfer_memory): To avoid dependency on
4271 where sections are in memory, try PT_WRITE_D and if that fails,
4272 try PT_WRITE_I. Most Unixes don't care which you use.
4274 * infrun.c (step_resume_break_shadow): Change to array to
4275 match other breakpoint shadow storage.
4276 (clear_proceed_status): Pass address of bpstat to
4277 bpstat_clear, not the bpstat itself.
4278 (child_create_inferior): FIXME comment about if the child
4280 (start_inferior): Remove old function.
4281 (child_open): Use target_kill rather than kill_inferior.
4282 (wait_for_inferior): Ditto.
4283 (insert_step_breakpoint, remote_step_breakpoint): Use
4284 new step_resume_break_shadow.
4286 * inftarg.c (child_wait): If all child processes die,
4287 pretend that the one being waited for exited with signal 42.
4289 * main.c (command_line_input): When scanning for comments,
4290 don't coredump on unclosed quotes.
4291 (quit_command): Use target_kill rther than kill_inferior.
4292 (_initialize_main): Rename class_user from "user" to
4295 * printcmd.c (print_command_1): Initialize "fmt" if no format
4296 is specified by the user.
4297 (print_frame_args): Only add to args_printed if we are
4298 actually fetching args from the stack (avoiding undefined
4300 (_initialize_printcmd): Remove bogus \{ from string.
4302 * remote-eb.c (eb_open): Avoid coredump on no argument.
4304 * remote-nindy.c: Bring out of Intel environment into new
4305 target environment. Remove all conditional compilation on
4306 I80960. Massive hacking throughout.
4307 (nindy_xfer_inferior_memory): New routine stolen from
4309 (nindy_create_inferior): New routine pieced together, probably
4310 not quite working yet.
4311 (nindy_ops): New target_ops struct for nindy.
4313 * remote-vx.c: Use write_memory rather than target_write_memory
4314 to get error checking.
4315 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4317 (vx_create_inferior): Use target_terminal_ours...
4319 * signame.c (_initialize_signame): Always initialize, since
4320 we need the table for things other than psignal.
4322 * solib.c (solib_add): Use symbol_file_add, not add_file.
4323 (solib_address): Return boolean result rather than struct
4324 pointer which nobody else knows the type of.
4326 * sparc-tdep.c, valops.c: Use write_memory rather than
4327 target_write_memory, to get error checking.
4329 * stack.c (locals_info, catch_info, args_info,
4330 get_selected_block, frame_command, up_command): Use
4331 target_has_stack, rather than have_inferior_p or
4334 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4336 * symfile.h: New file, defining the interface between the
4337 generic and object-file-specific symbol reading code.
4339 * symtab.c: Move generic symbol-reading interface to symtab.c,
4340 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4341 table to map BFD targets to symbol-reading modules in GDB.
4342 Change index to strchr.
4343 (lookup_struct_elt_type): Use error() rather than hand-made
4344 simulations thereof.
4345 (lookup_partial_symbol): Speedup slightly when length == 0.
4346 (symbol_file_add): New function.
4347 (symbol_file_command): Call it.
4348 (symfile_open, symfile_init): New function.
4349 (add_file_target_command, add_file_addr_command): moved from
4352 * target.c (target_command): use target_kill.
4354 * target.h (target_files_info): Don't declare, never called
4357 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4358 files to determine stack end address.
4360 * valarith.c (value_x_binop, value_x_unop): Change error message
4361 to be more useful. Pass proper argument to value_struct_elt.
4363 * valops.c (value_assign): FIXME comment that long long
4364 bitfields will break here.
4366 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4367 Update `make saber_gdb' to work better.
4369 * TODO: A woman's work is never done.
4371 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4372 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4373 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4374 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4375 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4376 valops.c, valprint.c, exec.c: Lint.
4379 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4381 Continuing Intel 960 port merge of GDB.
4383 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4384 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4385 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4386 Wack over "make depend" so it handles files in subdirectories
4387 vx-share, nindy-share, bfd, and in the current directory.
4389 * blockframe.c (get_prev_frame_info): Remove fatal error
4390 if stack not defined.
4392 * core.c (core_open, core_detach): New functions that handle
4393 the old "core-file" command as "target core" and "detach" instead.
4394 (core_file_command): Call them.
4395 (core_xfer_memory): Use common routine xfer_memory.
4397 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4398 dbxread now uses bfd for everything but symbol reading itself.
4399 BFD internals are used to drag out the relevant file offsets.
4400 (partial_symbol_file_open): Change args all around for BFD.
4402 * symtab.c: Rename "value" to "val" everywhere, so we can
4404 (symbol_file_command): New command, moved from dbxread.c
4405 and coffread.c. It uses BFD to read the file, then vectors
4406 based on its type, to dbx or coff symbol readers.
4407 * symtab.h: Extern a few vars for symbol_file_command.
4409 * target.h: Breakpoint takes a char * save area, not a char **.
4411 * valprint.c (val_print): When unpacking bitfields, offset
4412 the address in gdb of the value, if it is declared with a shorter
4413 type. Remove the last "runtime kludge test" of host byte order.
4415 * utils.c: Remove old my_bfd_read routine.
4417 * stack.c (frame_info): Use target_has_stack. Print program counter
4418 register's actual name rather than "pc", since it's called the
4419 "ip" (instruction pointer) on the i960 (sigh).
4421 * target.c (target_command): Add command for selecting a target
4422 type and calling its open routine. This is used for initiating
4423 communication with a particular target, in a generic way.
4425 * tm-i960.h: Update for modern gdb. Remove semicolons from
4426 various macros. Handle reading struct return convention, and
4427 error-out attempts to return structs with the "return" command.
4428 Be sure gdb doesn't think we know how to call functions in the
4431 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4432 to i960_xxx in lower case.
4433 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4434 not being defined yet.
4436 * remote.c (remote_open): Call start_remote to initialize
4437 wait_for_inferior during open.
4438 (remote_xfer_inferior_memory): Return length written rather
4441 * remote-vx.c (target_command -> vx_open): Use new generic
4443 * remote-eb.c, inftarg.c, exec.c: ditto.
4445 * infrun.c: Fix comments.
4446 (attach_program -> child_open): Use new generic target command.
4447 (wait_for_inferior): Clear saved register values before target_wait,
4448 so target_wait can set some of them if convenient.
4450 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4451 Return success indicator, not void.
4452 (child_xfer_memory): Avoid fetching initial word if we'll
4453 overwrite it anyway.
4455 * infcmd.c (attach_command): Use new generic target open routine.
4456 (_initialize_infcmd): Update doc on attach and detach commands.
4457 (do_registers_info): Merge in a byte-order problem as a FIXME
4460 * findvar.c (find_saved_register): Avoid problem in current frame.
4461 (read_relative_register): Ditto.
4462 (write_register): Convert byte order on the way out.
4464 * exec.c (file_command): Add.
4465 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4466 (xfer_memory): Common function between core_xfer_memory and
4468 (exec_xfer_memory): Use it.
4470 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4472 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4473 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4474 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4476 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4478 Merge Intel 960 port of gdb, continuing...
4480 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4481 symbol_file_command): Pass from_tty arg to hush 'em up.
4483 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4484 Add magic numbers for 960 COFF format.
4486 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4488 Merge Intel 960 port of gdb, from Intel "1.2" release.

4501 Tue May 29 12:54:49 PDT 1990
4502 Added variable baud rate (-b switch).
4503 Source code reorganization.
4505 Thu Apr 26 11:09:55 PDT 1990
4506 More cleanup of batch mode; specifically, execute "-s", "-e", and
4507 "-se" switches as soon as they are encountered on the invocation line.
4509 Fri Apr 20 13:47:15 PDT 1990
4512 Thu Apr 19 09:54:28 PDT 1990
4513 Add 'reset' command.
4515 Wed Apr 18 09:48:07 PDT 1990
4516 After opening remote tty, wait for 1 second to go by without input
4517 from it before trying to talk to NINDY (fixes problems with the
4518 Heurikon HK80/V960E).
4520 Mon Apr 4 16:33:05 PDT 1990
4521 Some output was not being suppressed in 'batch' mode.
4523 Thu Mar 22 15:31:11 PST 1990
4524 Ask user if old symbol table should be deleted when new file is
4527 Allow user to run a program downloaded before gdb960 was brought up.
4529 Correct "exec-file" help message for i80960 context.
4531 Correct bug in calculating user space address: could occasionally
4532 corrupt user program.
4534 Make sure to zero low-order bits in rip's because of bug in 960CA

4539 code loaded at addresses higher than 0x7fffffff.
4541 Wed Jan 10 12:43:22 PST 1990
4542 Open remote tty for exclusive use.
4544 Fri Jan 5 12:14:42 PST 1990

4546 opcode for sysctl is 0x659
4548 Mon Oct 23 12:03:04 PDT 1989
4549 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4551 Mon Oct 16 14:15:09 PDT 1989
4552 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4554 Mon Oct 2 15:56:31 PDT 1989
4556 Added 960CA disassembly support.
4558 To simplify maintenance:
4559 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4561 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4562 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4563 - made disassembly interface identical to that in gdmp960.
4567 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4569 * target.h: Allow targets to stack. Add target_has_memory,
4570 _registers, etc. Restructure memory access and "info files"
4571 to walk the target stack.
4572 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4573 target.c: Change tables to match target.h.
4574 * inflow.c (child_mourn_inferior): pop child_ops.
4575 (generic_mourn_inferior): Use new has_stack flag.
4576 * infptrace.c (child_xfer_memory): New memory regime.
4577 * inftarg.c (child_files_info): New "info files" regime.
4578 * remote-eb.c: New memory regime, new info files.
4579 * remote-vx.c: New memory regime, new info files. Now use
4580 separate targets for VxWorks attachment to machine, and
4581 actually running a process under VxWorks, since one has
4582 stack & execution & regs and the other doesn't.
4583 * remote.c: New memory regime, new info files.
4584 * sparc-xdep.c (fetch_core-registers): New memory regime.
4585 * target.c: New routines and support for stacked targets,
4586 new memory regime, new info files regime.
4589 Generalize section handling for an arbitrary number of sections,
4590 including use of the new BFD (binary file) library.
4591 * gdbcore.h: Add struct section_table.
4592 * exec.c (build_section_table): Iterate all sections and
4593 record what gdb needs to know about them.
4594 (exec_command): Use it.
4595 (exec_xfer_memory): Use the table.
4596 (exec_files_info): Print the table.
4597 * core.c (core_file_command, core_xfer_memory, core_files_info):
4599 * source.c (find_source_lines): Use bfd_get_mtime.
4600 * dbxread.c: Quick changes to make it compile with new BFD.
4601 * utils.c (error): Avoid using bfd_error in generic routines.
4603 * core.c (core_fetch_registers): Get from the ".regs" section of
4605 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4607 * inferior.h (attach_flag): Export.
4608 * infcmd.c (run_command): use new target_create_inferior.
4609 * infrun.c (child_create_inferior): Don't return result.
4610 * Makefile.dist (VERSION): 3.91.4.
4612 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
4614 * breakpoint.c (bpstat_num): Handle breakpoints which have
4615 since been deleted, such as temporary breakpoints.
4616 infcmd.c (program_info): ditto.
4618 * core.c (core_file_command): Display the frame where the core
4623 * remote-vx.c (target_command): Merge in target command from
4624 targ-vx.c. A few other cleanups.
4626 * TODO, Projects: Lots more stuff to do...
4628 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4630 Massive changes to wall off the remote-debugging interface
4631 behind a function vector. The port to handle VxWorks targets
4632 is also part of this.
4634 All files: Replace references to renamed functions,
4635 remove references to remote_debugging, remove references to
4636 have_include_file, have_core_file in favor of target_has_stack,
4637 target_has_memory, etc.
4639 * Modularize the breakpoint interface.
4640 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4641 a breakpoint instruction.
4642 breakpoint.c: struct breakpoint's shadow_contents now sized as
4644 (insert_breakpoints): Vector to target to install breakpoints.
4645 (remove_breakpoints): Vector to target here too.
4646 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4647 sparc-tdep.c (single_step): Use new breakpoint interface for
4648 the single-step breakpoints.
4649 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4650 New file, contains routines to insert and remove breakpoints by
4651 reading out the old contents and later replacing them. This is
4652 how ptrace breakpoints work, and many remote systems as well.
4654 * tm-vxworks68.h: New config file, overrides a few things for
4655 Wind River's preferences.
4657 * target.h: New file, for transfer vector used to talk to the
4658 inferior (child, attached, core, exec, remote, etc). All accesses
4659 to the thing being debugged should come through these vectors.
4660 target.c: New file, routines to handle transfer vector.
4661 (various files): Add transfer vectors XXX_ops for the various
4662 targets and pseudo-targets (core files, etc) we support.
4664 * breakpoint.c (bpstat_stop_status): Further explorations of
4665 watchpoints and why things don't work all the time.
4666 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4668 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4669 the local gdbinit if it doesn't already have it.
4671 * core.c (core_ops): add and install.
4672 Allow core debugging without exec file.
4674 * dbxread.c (free_and_init_header_files): Merge two fns.
4675 (end_symtab): Free named symbol table when a new version comes in.
4676 (read_dbx_symtab): Relocate all kinds of symbols with base
4677 address. First step toward handling different text, data, bss
4679 (add_file_addr_command): Renamed add_file_command.
4680 (add_file_command): Vector to remote handler.
4681 Add "load" as an alias for "add-file" command.
4683 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4684 non-returning functions.
4686 * exec.c: Add exec_ops, and push it as a target when an exec
4689 * infcmd.c (run_command): Pass executable file name and arg list
4690 separately when starting an inferior. Permit "run" when no exec
4691 file is specified, for VxWorks.
4692 (detach_command): Move to child_detach in inftarg.c.
4694 * inftarg.c: New file. Unix-child-specific routines, and the
4695 child_ops structure.
4697 * inferior.h (registers): Export "registers" as the way for
4698 target dependent register handlers to find gdb's local copy of
4699 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4700 since it is now used by places that want wait_for_inferior to
4701 handle the grunge but want to see every trap from the inferior.
4703 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4704 Eliminate remote_debugging hooks in terminal handling.
4706 * infrun.c: Replace start_inferior with child_create_inferior.
4707 Move all the hair of Unix shells and ptrace idiosyncracies into
4708 child_create_inferior, so remote handlers don't have to deal.
4709 Remove running_in_shell. Rename stop_after_attach to
4710 stop_soon_quietly, and use it in a few other places where we want
4711 to just call wait_for_inferior and get control back on the first
4712 trap. trap_expected now never takes a value > 1.
4713 (init_wait_for_inferior): Initialize static vars when a new
4716 main.c (gdbinit): Add new hook for .gdbinit file name, let
4717 it be overridden by config files as GDBINIT_FILENAME.
4718 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4719 Both of these are used for VxWorks gdb.
4721 mcheck.c: rename include file "gmalloc.c" to avoid problems
4722 with system include file "malloc.c".
4724 param-no-tm.h: New include file, same as param.h but does not
4725 include the default "tm.h" file. This is used in files where
4726 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4728 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4730 remote-vx.c: New file, VxWorks remote debugging support. Uses
4731 RPC routines that are shared with the target system, in directory
4734 remote.c: Vectorize remote interface.
4736 source.c: Globalize source_path, and make an alias "l" for "list"
4737 since we now have the "load" command.
4739 sparc-xdep.c: Use new param-no-tm.h.
4741 symmisc.c (free_named_symtab): Add new function from Wind River.
4742 However, ifdef it out for now while we think about what it should
4745 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4747 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4748 non-Unix-children handle this with their own code in the target
4751 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4752 source and target lists. Add vx-share to default list of include
4753 directories. Add new files to src and target lists: mem-break,
4754 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4755 ${srcdir} versions of munch and createtags are used.
4757 * valops.c (find_function_addr): Split out of call_function.
4758 (call_function_by_hand): Rename call_function; this function
4759 calls functions in the target by laboriously patching the target
4760 word-by-word with the right stack, args, regs, etc.
4763 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
4765 Handle AMD 29000 a bit better.
4767 * remote-eb.c (readchar): Mask received char log to make it readable.
4768 (remote_start): Pass arguments down to executing program.
4769 Make startaddr unsigned.
4770 infrun.c (start_inferior): Accept args, pass them to
4772 infcmd.c (run_command): Pass args down to start_inferior.
4774 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
4775 the target object file format.
4776 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
4778 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
4779 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
4781 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
4783 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
4784 * TODO: We did a few things, we have more to do though.
4786 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
4787 * inflow.c (inferior_died): Clear deferred stores.
4789 * Debug problems with dummy frames and calls to the inferior.
4790 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
4791 * sparc-tdep.c (do_restore_insn): Simplify.
4792 (sparc_frame_find_saved_regs): Simplify and fix what we find.
4793 (sparc_push_dummy_frame): Simplify and fix what we push.
4794 (sparc_pop_frame): Slightly more hair here, deciding whether
4795 we are restoring a saved PC or returning to a return address in %i7.
4796 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
4798 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
4799 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
4800 * obstack.h (chunkfun): ditto.
4801 * defs.h (xmalloc, xrealloc): ditto
4803 * utils.c (quit): Grab the terminal from the child if necessary.
4805 * inflow.c (term_status_command): Rename to term_info, change
4808 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
4809 (is_delayed_branch): Speed up.
4810 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
4811 Still missing some float ops, and needs testing.
4813 * Support for input and output radixes other than base 10
4814 * defs.h (input_radix, output_radix): Declare.
4815 * expread.y (yyparse, parse_number): Handle changes of input
4816 radix, and ambiguous names-or-numbers in radixes >10.
4817 * printcmd.c (print_scalar_formatted): Print formatted hex
4818 numbers in varying column widths.
4819 * valprint.c (val_print): Use output_format to print scalar ints.
4820 (set_input_radix, set_output_radix, set_radix): Create.
4821 (set_output_radix): Set output_format from output_radix.
4822 (_initialize_valprint): add `set radix' but leave the others off.
4824 * main.c (execute_command): Let stupid questions be turned off.
4825 (_initialize_main): Handle "set stupidity", etc.
4827 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
4828 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
4830 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
4832 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
4833 bfd stuff is still screwed up, but with some manual work, it
4836 * breakpoint.c (bpstat_do_actions): Start over if a command
4837 proceeds the inferior, since the inferior will have stopped and
4838 will need to have its new stop-actions taken care of.
4840 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
4841 compiler fits, simplify it.
4843 * gdb.texinfo (directory command): Doc new dir command.
4844 source.c (directory_command): "dir" now puts things on the front
4845 of the path, moves dups up front, and handles multiple names
4846 on the command line, inserting each one in order. It also
4847 blows away cached line and full_filename info.
4849 * stack.c (backtrace_command): Skip "more stack frames follow"
4852 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
4853 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
4854 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
4855 The only odd one was Gould NP1, which had defined vprintf to
4858 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
4859 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
4860 variable, inspect_it.
4861 valprint.c (print_string, val_print): Use the global inspect_it
4862 to indicate whether to print in Epoch style or normal style.
4864 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
4866 * printcmd.c (call_command): add an alias for the "print" command
4867 which runs expressions and doesn't print the result if void.
4868 (print_command_1): implement it.
4870 * command.c: Remove #if 0'd code. Initialize all the fields
4871 in add_cmd (). Rename do_nothing_command to
4872 not_just_help_class_command, and make it externally visible.
4873 command.h: add user_commands to struct.
4874 * main.c (define_command): Don't overload c->function with a char
4875 string as well as a function pointer.
4877 * eval.c (evaluate_subexp): Reinstall tiemann changes to
4878 calling convention of value_struct_elt () that got dropped in
4881 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
4882 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
4884 * tm-sparc.h (POP_FRAME): replace some constants with defines.
4886 * sparc-xdep.c (store_inferior_registers): defer stores to regs
4887 until a good time (e.g. when we are about to run the child),
4888 saving ptrace calls.
4889 * infrun.c (proceed): handle DO_DEFERRED_STORES.
4890 * tm-sparc.h: define DO_DEFERRED_STORES.
4892 * sparc-xdep.c (store_inferior_registers): when storing float
4893 registers, don't store stack regs too. When storing the SP,
4894 however, DO store the stack regs too. This fixes a bug in which
4895 the dummy frame is not recognized when a call_function finishes,
4896 because its frame pointer (in the stack regs) was never
4898 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
4899 even though we don't know how to read them from an inferior.
4900 valops.c (call_function): Comment about storing SP.
4902 * infrun.c (save_inferior_status): Save away the original bpstat
4903 chain so it can be restored later. Install the copied version for
4904 use by whoever saved the status. It will be blow away by
4905 restore_inferior_status, and the original chain restored. This is
4906 important for people who have pointers into the original.
4908 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
4909 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
4910 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
4913 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
4915 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
4916 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
4917 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
4919 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
4921 * Merge Mike Tiemann's multiple inheritance changes from Sun.
4922 Store the baseclasses in a type struct starting from array element
4923 0 rather than from the unusual array element 1.
4925 dbxread.c: the above.
4926 (virtual_context): Add
4927 Read new debug information about which virtual function table
4928 a virtual function is from, and store it in fn_field.fcontext.
4930 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
4931 TYPE_FN_FIELD_STATIC_P.
4933 symtab.c: the above.
4934 valops.c: the above. Handle pointer casts of object *'s.
4935 (search_struct_method): Add.
4936 (value_struct_elt): First arg is now a pointer to a value, and is
4939 valprint.c: the above.
4940 values.c (value_virtual_fn_field): Add type arg. Handle
4941 offsetting to the proper object when calling virtual fns.
4943 (baseclass_addr): Add valuep arg.
4945 * README: Document the current state of BFD config (missing).
4946 * TODO, ChangeLog, Makefile.dist: Roll version.
4947 * WHATS.NEW: Add summary of changes since 3.5.
4949 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
4951 * dbxread.c (read_struct_type): Clear bit vectors whenever
4953 symtab.c (B_CLRALL): define.
4955 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
4956 using == rather than =. Huh... This fixes the dreaded problem
4957 wherein builtin_type_int becomes TYPE_CODE_FLT.
4959 * core.c (info_files): Show the inferior pid.
4961 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
4962 already knows how to look in the source directory.
4964 * Remove psymtab hair from many places. Remove duplicated code
4965 for searching symbol tables. Hide psymtabs from most places.
4966 Make it fast to get from a psymtab to its symtab.
4968 blockframe.c (blockvector_for_pc): Remove psymtab hair.
4969 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4970 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4971 dbxread.c: export psymtab_to_symtab, make it work if called N times.
4972 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
4973 new symtab completely. New psymtabs get symtab pointer
4974 initialized to zero. Remove MI warning printf.
4975 symtab.h: Comments. Add psymtab to symtab pointer.
4976 (PSYMTAB_TO_SYMTAB): New macro.
4977 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
4978 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
4980 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
4982 (print_frame_info): Avoid special-casing symbols that have not yet
4985 * source.c (open_source_file): Quick path if we have already
4986 located the source file by its full name.
4988 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
4989 find_pc_psymtab. When a name is found in the misc function
4990 vector, search the symbol table for its mangled name, not the
4991 name that the user typed.
4993 * bfd.h: Fix missing comment terminators, make #endifs match.
4995 * valarith.c (value_less): Handle unsigned int comparisons.
4996 Add FIXME about pointer compares, which assume host and target
4997 pointers are the same.
4999 * command.c (do_nothing_command): lint
5000 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5001 fix comments on debug symbol format for visibility. Actually set
5002 visibility of symbols.
5003 main.c (echo_command): lint; use <readline/history.h>.
5004 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5005 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5006 pointing past end of allocated memory; saber complains.
5007 obstack.h: Declare the external functions that we use.
5008 valarith.h: use <string.h>
5009 solib.c (solib_add): lint.
5011 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5013 * main.c (initialize_main): Default info_verbose to off, now that
5014 symbol reading is fast.
5015 (quit_command): Avoid clobbering exec_bfd while quitting.
5017 * Initial BFD (binary file diddling library) merger:
5018 coffread.c: Change AOUTHDR to struct exe_hdr.
5020 core.c: initialize initialized data at compile time.
5021 (core_file_command): Move from coredep.c, convert to bfd.
5022 (xfer_core_file): Convert to bfd.
5023 exec.c (exec_file_command): use bfd routines.
5025 mips-tdep.c: Remove exec_file_command and friends.
5028 * coredep.c: (fetch_core_registers) Convert core_file_command to
5029 fetch_core_registers.
5030 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5032 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5033 (my_bfd_read): More bogosity, which I don't think we call.
5034 (program_name): Remove this atrocity asap!
5036 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5039 values.c: allocate_repeat_value was not clearing the
5040 optimized_out field.
5041 (value_static_field): minor stylistic fix (wrong macro was used).
5042 valops.c (value_struct_elt_for_address): didn't work for C++
5045 * signame.c (_initialize_signame): Initialize signal names once.
5047 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5048 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5049 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5051 * remote-eb.c: Support user-settable baud rates on the serial port.
5053 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5055 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5057 * tconfig/sun3os4: Remove warning about native assembler,
5058 since it also occurs in the xconfig file.
5060 * findvar.c (registers): Allocate some slop after `registers'
5061 to prevent stray accesses from trashing the next variable.
5063 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5064 on the sun-3, by changing the #ifdef from `sun3' (which is not
5065 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5066 vars, which happened to follow `registers' in the executable.
5068 * readline/history.c (history_search): Heed gcc-2's advice
5069 and parenthesize && inside ||).
5071 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5072 tm-29k.c: Insert FSF copyright headers.
5074 * remote-eb.c: Better comments.
5076 * Makefile.dist: Update to 3.91.6.
5077 * TODO: note PREPARE_TO_STORE problem.
5079 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5081 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5083 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5085 * infrun.c (wait_for_inferior, at end): Don't set up
5086 prev_* if the inferior no longer exists.
5088 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5089 CANNOT_EXECUTE_STACK.
5090 valops.c (call_function): Use it.
5092 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5094 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5095 infrun.c (wait_for_inferior, 2 places): Use it.
5097 * values.c (value_being_returned): Only use
5098 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5100 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5101 right thing for remote-eb.c.
5103 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5104 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5106 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5107 (FRAME_FIND_SAVED_REGS).
5109 * findvar.c ({fetch,store}_registers): Check for
5110 REMOTE_{FETCH_STORE}_REGISTER macro.
5112 * findvar.c (get_saved_register): Add argument lval and
5113 change meaning of argument addr.
5114 findvar.c: Change calls to get_saved_register to reflect
5115 new calling convention.
5116 valops.c (value_assign): Use get_saved_register instead of
5117 find_saved_register.
5119 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5121 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5122 an (uninitialized) pointer to one. Use "&" when passing it
5125 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5127 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5130 * coffread.c (symbol_file_command): Put semicolon after
5132 Put safe_to_init_tdesc_context in #if defined (TDESC).
5133 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5134 coffread.c: #include <sys/stat.h>.
5135 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5136 Add missing ')' in check for "lc%" and friends. Remove
5138 Declare read_one_sym() at top of file.
5139 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5140 MC68WRMAGIC can have the same value without causing a duplicate
5143 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5145 * Allow a Makefile to be built without building the
5146 tm and xm file links that screw up builds in subdirectories.
5147 This is done with `config.gdb none', then you can do things
5148 like `make gdb.tar.Z'.
5149 * tconfig/none: Config file for no target system
5150 * xconfig/none: Config file for no host system
5151 * config.gdb: If no TM or XM files are called out by the
5152 host or target file, don't make links for them.
5154 * cplus-dem.c: Add documentation.
5156 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5157 simple error, so the user's gdb doesn't crash due to some object
5158 file problem (e.g. somebody is rebuilding the file out from under
5161 * printcmd.c (print_address_symbolic): demangle the symbol.
5163 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5164 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5165 (alldeps.mak): sort and uniq all results from this; duplicates
5166 hose gdb.tar.Z link building. Remove RCS files from
5167 tconfig and xconfig. Add config files for sun386. Add
5168 a few odd files to OTHERS and HFILES.
5170 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5172 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5173 Roll version number to 3.91.5. Make lint work in bindir.
5175 * README: Document cross-debugging and new file structure.
5177 * blockframe.c: Lint. Include "value.h" to declare read_register.
5178 (find_pc_partial_function): remove duplicate line.
5180 * command.h: Lint. Declare error_no_arg and dont_repeat.
5182 * tm-news.h: Remove inadvertently duplicated stuff.
5184 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5185 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5187 * config.gdb: Allow `config.gdb host target' form. Clean
5188 up previous change that printed bogus messages when you just said
5191 * core.c: #include "command.h" for lint.
5194 * main.c: Remove some casts of enums. Lint.
5201 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5203 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5204 read it from memory. This will allow us to save ptrace calls
5205 eventually. Changed caller single_step too.
5207 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5208 that we aren't going to use, saving many ptrace calls, especially
5209 when watchpointing or single stepping. Use some #define's for
5211 (store_inferior_registers): Ditto.
5212 (core_file_command): Use some #define's for constants.
5214 * tm-sparc.h: Add #define's for some register numbers, so we
5215 can eliminate the use of random constants in sparc-xdep.c.
5217 * stack.c (frame_command, print_frame_info, up_command,
5218 down_command) Remove frame_changed, since it
5219 causes a bug and doesn't seem to do anything useful. In some
5220 places it was used as a flag, in others as a stack level (?).
5222 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5223 default is to use the portable (vprintf) version rather than the
5225 * xm-news.h (MISSING_VPRINTF): Add.
5227 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5229 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5231 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5232 about linking debugged programs -Bstatic in the sun?os4 config
5233 files in tconfig and xconfig subdirectories.
5235 * main.c (main): Remove unreached exit(0) now that we exit
5238 * Create TODO file for online bug list. There are too many
5239 "little" bugs to keep track of on paper.
5241 * Change Projects file to refer to bug-gdb@cygnus.com
5242 rather than kingdon@ai.
5244 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5246 * Makefile.dist (VERSION): 3.91.4 now.
5248 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5249 (condense_misc_bunches): Add sanity check that misc_count is
5250 the same as the number of symbols in the bunch.
5252 * coffread.c: rename init_misc_bunches. Pass an argument
5253 to condense_misc_bunches (a zero).
5255 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5256 every time we are called; don't rely on our caller to do it.
5257 (add_file): Remove call to init_misc_bunches.
5259 * mipsread.c: Only warn, don't error, if unknown symbol types.
5260 This keeps an old gdb from falling on its face if it sees newly
5261 extended symbol info. Rename init_misc_bunches.
5263 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5265 * Merge in changes from Per Bothner for DECstations and other
5266 MIPS stuff. The rest is Bothner speaking:
5268 The next message is a merger of Alessando Forin's mips port with
5269 mine. I've tried to use my good if biased judgment to get
5270 the best of both. It *does* need testing.
5272 Some of the changes are general, *not* mips-specific.
5275 Didn't believe in little-endian bit order.
5276 There are still inconsistencies about whether flags
5277 like BITS_BIG_ENDIAN are integer (#if ...) or
5278 boolean (#ifdef ...). I tried to paper over them.
5280 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5281 Moved some misc_function code that was common to
5282 {dbx,coff,mips}read.c to symtab.c.
5283 In the process, I think I cleaned things up a bit.
5284 At the same time, moved obsavestring and obconcat to symtab.c.
5287 Removed obsolete condense_addl_misc_bunches (use
5288 condense_misc_bunches(1) instead).
5291 Needed to include <sys/dir>, at least on DECstations.
5293 valops.c, mips-tdep.c, tm-mips.h:
5294 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5295 conventions (when STACK_ALIGN is insufficient).
5296 Needed on mips, where doubles need 8-byte alignment,
5297 but ints only need 4.
5300 Removed cruft that was not being used.
5301 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5304 Print $ before register-names (I think that makes things a little
5306 Never print two instructions, even if one delays.
5307 Removed hex-disassemble set_cmd. (This is not mips-specific,
5308 so I think the argument is whether it is generally worthwhile or not.
5309 I'm inclined to think not, given how easy it is to
5310 convert between radixes in gdb.)
5313 This is basically Alessando's code.
5314 It doesn't use obstacks; I changed it to use obstacks
5315 in a few minor places where using malloc causes a
5316 memory leak. (Probably, more places could/should be changed.)
5317 I added record_misc_function where it was missing.
5318 In symbol_file_command and add_file_command, I tried
5319 to make the code consistent with more recent versions.
5320 Minor sylistic changes in parse_procedure.
5321 Make a .gdbinfo. psuedo-symbol point back to the real
5322 procedure symbol (using the isym field).
5325 This is basically from my port, but with a lot of details
5326 and a number of routines merged in from Alessando's version.
5327 I basically used my code "raw" backtrace (use heuristics
5328 from the actual code, rather than symbol table info) - though
5329 the idea is Alessandro's. I feel my code is a little cleaner
5330 here, particularly in being a little more flexible, such as being
5331 able to handle gcc-produced code (which it now can).
5332 It also doesn't do frame caching (which is not useful
5333 more recent gdb versions).
5334 I also used my code for push_/pop_dummy, more or less.
5335 I tried to incorporate AF's code for testing sigtramp
5336 while backtracing; I probably got it wrong.
5337 Added mips_print_register, which tries to scrunch as much
5338 information as possible on a screen...
5339 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5340 under mips-pinsn.c), I don't see anything mips-specific here,
5341 and I don't see it being all that useful anyway.
5344 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5345 Use more register names (rather than hard-cases numbers).
5347 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5349 * Hack up 3.90.11 changes:
5351 * Makefile.dist (depend): parameterize $(GCC).
5352 Add solib.c and solib.o.
5353 (readline): Fix vpath for both absolute or relative SRCDIR.
5355 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5356 Also, let the part I didn't understand at least compile so
5357 I can test the rest. FIXME.
5359 * dbxread.c: Fix thinko using strcmp.
5360 (init_psymbol_list): declare static.
5361 (partial_symbol_file_open): Comment cleanups better, avoid
5362 cleaning up the string table since the caller will do that.
5363 Move the stat for mod time into symbol_file_command, temporarily.
5364 (There should be a mod time for each symbol file, eventually,
5365 to control its rereading. FIXME.)
5367 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5368 SunOS, which gives error for shared libs otherwise. (From
5369 Schaefer, probably FIXME needs work for portability.)
5371 * solib.c: Move #include "param.h" to work.
5372 Lowercase all the Uppercase Letters In the Messages.
5373 (find_solib): Clean up inferior_so_name for debug printouts.
5374 Allow no argument, to mean all shared libraries.
5376 * symmisc.c: include param.h to get CLEAR_SOLIB.
5378 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5380 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9

5410 * Changes for Sun shared libraries:
5411 blockframe.c (find_pc_partial_function): If a non-text symbol
5412 is found, set *address = pc - FUNCTION_START_OFFSET.
5413 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5414 Disable breakpoints instead of giving an error.
5415 source.c (select_source_symtab): Initialize cs_pst.

5420 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5421 (record_misc_function): Give correct type for N_DATA symbols.
5422 (condense_misc_bunches): do "misc_function_count = j" regardless
5424 Take code which is shared between symbol_file_command and
5425 add_file_command and put it into partial_symbol_file_{open,read}.
5426 Split add_file_command into add_file_command and add_file.
5427 Make psymtab_to_symtab read in the string table if the file
5429 Two new parameters to read_dbx_symtab and start_psymtab.
5430 tm-sunos.h: New file.
5432 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)

5439 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5441 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5443 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5444 size 1,2,4,8 rather than size < 8.
5446 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5447 as necessary, not just once.
5449 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5451 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5453 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5455 * tm-news.h: Add CALL_DUMMY_*.
5457 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5459 * config.gdb: In list_host, list_target, use ${i}, not $i.
5461 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5463 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5465 * sparc-opcode.h: Change all store floating-point state register
5466 instructions to have the right match & lose fields.
5468 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5470 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5472 config.gdb: If srcdir != ., create readline directory and
5473 copy a makefile into it.
5475 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5476 consistency with POSIX.
5478 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5479 when we exit its exp_valid_block.
5481 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5483 * Makefile.dist: Bump version to 3.91.3.
5485 * Clean up handling of breakpoint commands (somewhat).
5486 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5488 inferior.h: Add breakpoint_proceeded to inferior status struct
5489 and globals; save it and restore it.
5490 (clear_breakpoint_commands): Cleanup, remove old #define.
5492 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5493 (save_inferior_status, restore_inferior_status): handle it also.
5494 (proceed): Remove earlier code that set breakpoint_proceeded.
5495 It is now set only in clear_proceed_status.
5496 (clear_proceed_status): Cleanup, use bpstat_clear rather
5497 than clear_breakpoint_commands. No callers need the stop_bpstat
5498 between clear_proceed_status and proceed.
5500 infcmd.c: Add breakpoint_proceeded definition and comment.
5501 (cont_command, jump_command, signal_command): Move call to
5502 clear_proceed_status right next to call to proceed.
5504 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5505 caller's argument while running down the chain of breakpoints.
5506 Use new variable "breakpoint_proceeded" to determine when
5507 a command that it executes moves the inferior past the
5509 (bpstat_clear): Handle NULL argument.
5510 (bpstat_clear_actions): Avoid useless call to
5511 breakpoint_auto_delete.
5512 (delete_breakpoint): Clean up bpstat's that are pointing to
5513 the deleted breakpoint from the stop_bpstat chain.
5514 (breakpoint_auto_delete): Simplify.
5516 * Clean up handling of EOF, error on stdin, etc. This was
5517 prompted by a network problem that caused gdb to go into an
5518 infinite loop filling up its malloc'd memory.
5520 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5521 not clear_breakpoints_commands, which is now gone.
5522 (main): If command_loop returns (e.g. from EOF on stdin), do
5523 a quit_command (looping back to command_loop if quit_command
5524 doesn't really quit).
5525 (command_loop): check result from command_line_input and
5526 exit if it returns NULL, rather than passing the NULL to
5528 (gdb_readline): Free malloc'd result space before returning
5531 * utils.c (query): Handle C-d to mean "yes", just as if the
5532 input was not a terminal. Also avoid infinite loop if EOF
5533 occurs in mid-input-line before newline. This allows
5534 query to be used at EOF on stdin with reasonable results.
5536 * infrun.c (proceed): Set breakpoint_proceeded.
5538 * values.c (value_as_long): Avoid infinite recursion for enums.
5539 (_initialize_values): Fix typo in help msg (kingdon).
5541 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5542 RL_LIB for linking. This allows -lreadline for linking
5543 and nothing for dependencies, once readline is a real library.
5545 * config.gdb: Jim Kingdon: give useful error message if the
5546 host or target type is not recognized.
5548 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5549 it just defines it. Dumb, but deal with it.
5551 * Jim Kingdon suggests:
5552 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5554 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5556 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5558 * Clean up Bothner's changes.
5560 * blockframe.c (clear_pc_function_cache): New function.
5561 * blockframe.c: remake cache_pc_function_* static.
5562 * dbxread.c (symbol_file_command): remove references to
5563 cache_pc_function_* variables.
5564 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5565 * printcmd.c: Avoid kludging a global variable (addressprint)
5566 to avoid printing the address of a string twice. Instead,
5567 pass the format letter 's' down low enough that it can be seen
5568 to avoid this problem.
5569 (print_formatted): Pass format arg to value_print.
5570 (restore_addressprint): Remove function.
5571 (do_examine): Avoid hacking addressprint, cleanups and such.
5572 (print_frame_args): Add a comment to a Bothner change.
5573 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5574 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5575 to wipe out the values cached in blockframe.c.
5576 * symtab.c (find_method): Add comment saying how big you must
5577 allocate to be "big enough". Per being terse again.
5578 * valprint.c (val_print): Handle format letter "s" to print
5579 strings without addresses. Add comment to vtbl printing code
5580 which casts with wild abandon. Rearrange reference-printing
5582 @0xaddr: value (print w/addressprint)
5583 value (print w/~addressprint)
5584 @0xaddr (parameter lists w/addressprint)
5585 or nothing (parameter lists w/o addressprint)
5587 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5589 * Merge more changes from Per Bothner:
5591 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5592 annoying) that I tried to improve it. Here are my suggestions.
5594 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5597 Do automatic de-reference when taking the address of a reference.
5599 Don't deref_ref when printing parameter lists.
5601 More attempts at treating refernences properly.
5603 In val_print, if deref_ref==0, don't print dangling " = ".
5605 Add COERCE_REF macro, which de-references an REF.
5607 * Merge changes from Per Bothner:
5609 * Fixed (Sony news)-specific configuration problems.
5610 * Fixed other problems with using vanilla pcc and libc (enum problems;
5611 assumption that vsprintf exists).
5612 * Some major speed-ups (finc_pc_partial_function now caches a match;
5613 parsing avoids duplicate symbol_lookup calls).
5614 * Changed handling of baseclasses (no longer use baseclasses field
5615 of struct type, use the first n_baseclasses fields instead).
5616 * Various minor changes/fixes, most C++-related.
5619 Cache the most previous match from find_pc_partial_function.
5620 (Save both low and high ends of matching function's pc range.)
5621 This speeds up the loop of infrun.c:wait_for_inferior quite
5622 a bit, and makes step/next commands much zippier.
5624 Added an enum->int cast (otherwise, some compilers barf).
5626 No longer set baseclass offset to 0, since multiple
5627 inheritance now mostly works.
5628 Added a number of casts, to shut up compiler warnings
5629 (after stabs where made enums, not ints).
5630 When discarding a symbol table (in symbol_file_command),
5631 must clear the cache introduced in blockframe.c.
5632 Don't convert $vtbl_ptr_type to vtbl any more.
5633 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5634 Mask off sign bit emitted by g++ for virtual table offset.
5635 Set voffset to -1 (not 1) for static member functions.
5637 Changed parsing/lexing of names to avoid doing symbol lookup twice
5638 (once when lexing to determine symbol class, once for real).
5639 Now only call symbol_lookup once. Fields of 'this' win especially big.
5641 Subpress printing addr twice in the case of 'x/s addr'.
5643 lookup_basetype_type is no longer used.
5644 Add find_methods as recursive helper function to decode_line_1.
5645 This allows multiple inheritance to work.
5646 Also, once one or more matches has been found, do not look in
5647 base-classes. (Baseclass methods would be overridden, anyway.)
5649 Removed baseclasses array in struct type.
5650 Instead of using baseclasses[i], use fields[i-1].
5651 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5652 Changed sign convention of voffset (previous was inconsistent).
5654 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5656 Used to assume existence of vsprintf. Re-written to not need it
5657 if HAVE_VPRINTF is undefined.
5659 typecmp was too pessimistic. Made it less so.
5661 Don't print space after address.
5662 If vtable points to a misc symbol (with 0 offset), print it,
5663 since that indicates the actual class of the object.
5664 Changed ype_print_derivation_info to use new inheritance
5665 scheme (without baseclasses vector).
5667 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5668 Also, changes needed because TYPE_BASECLASSES were removed.
5670 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5672 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5675 If there is no path set, and the symbols don't indicate what directory
5676 a file was compiled in, look in the current directory. But either
5677 a path or a known compilation directory will prevent this.
5680 Three independent bug fixes:
5681 * Remove the #if 0 block that breaks some stuff.
5682 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5683 adapt gdb to either SunOS 4.0.* or 4.1.
5684 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5687 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5690 (type_print) Demangle the name being printed.
5691 (type_print_base) Handle botched demangling without coredump (tiemann).
5694 (check_stub_method): Document routine.
5695 (tiemann) fix bug for no-arg functions
5696 Avoid clobbering beyond end of malloc'd storage.
5697 Terminate the argument list properly.
5699 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5701 * Changes merged by John Gilmore:
5704 In breakpoint_1, use new print_address_symbolic instead
5705 of find_pc_partial_function. (This forces use of assembler-level
5706 addresses, and avoids misleading non-mangled source-level names.)
5708 Generalize ansi argument such that -1 means skip arglist totally.
5709 Removed global variable print_ansi_qualifiers (which made
5710 code non-reentrant), in favor of extra explicit arguments
5711 to internal routines.
5713 Add new helper function print_address_symbolic.
5714 Use find_pc_misc_function instead of find_pc_partial_function
5715 (since we want assembler-level symbols here).
5717 Print unknown function as just "f (...)", not "f (...) (...)".
5718 Use new fputs_demangled explicitly.
5720 Fixed a typing violation (problem: value.h cannot be imported
5721 without renaming many variable in this file).
5722 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5723 decode_line_1: Moved forward some never-reached code.
5724 Made decode_line_2 skip function prologues correctly.
5726 fputs_filtered should not demangle by default.
5727 Add new fputs_demangled to demangle on demand..
5729 Change value_struct_elt to use value_primitive_field (using recursive
5730 utility function search_struct_field). This allows foo.bar to work
5731 for multiple inheritance (so far only for data fields).
5732 Change check_field in the same way (recursive helper function
5733 to support multiple inheritance).
5734 (Note: there are more of these problems that I haven't fixed.
5735 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5736 value_of_this: 'this' symbol name is now just "this", note "$this".
5738 Don't print static members.
5739 Avoid printing "members of <type>" if there are none.
5740 Simplified type_print_derivation_info by merging duplicate code.
5741 Remove useless blank lines in type_print_base (ptype command).
5743 Added declaration of new routine value_primitive_field.
5745 Added value_primitive_field which is generalized version of
5746 value_field that can handle multiple inheritance (non-zero offsets etc).
5747 Re-implemented value_field to call value_primitive_field.
5749 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
5751 * infcmd.c -- insert else to avoid 'delete env' coredump when you
5752 delete the whole environment. Karl Berry reported the bug.
5753 * source.c - fix openp to avoid //'s in filenames, which
5754 trigger an Emacs bug causing it to not be able to find files
5755 when running gdb in a window.
5756 * dbxread.c - zap the #if 0 that botches the add-file code.
5757 It seems to work a lot better without all the code commented out.
5759 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
5761 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
5764 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
5766 * Makefile - added a ${CFLAGS} to a couple of entries,
5767 added remote-sa.sparc.c
5768 * added remote.sa-sparc.c, a modification of remote.c
5769 which conducts a dialog directly with the SparcStation prom.
5770 * breakpoint.c, infrun.c, sparcdep.c added
5771 remote_insert_breakpoint(), and remote_remove_breakpoint()
5772 to breakpoint.c instead of directly writing breakpoint instructions.
5773 * sparcdep.c on remote_debugging,there is no need
5774 to remove signle step breakpoint instructions.
5775 * main.c added "-epoch" flag and "int epoch_interface" to main.c
5777 * printcmd.c - epoch interface sends lisp expressions to open up
5778 epoch windows on inspection.
5779 * valprint.c - added arrayprint, and addressprint and made adding
5780 format controls easier
5781 * wait.h added a couple of undef's because we were getting
5782 complaints about WSTOPSIG and WTERMSIG begin redefined.
5785 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
5787 * symtab.c (decode_line_1): Add support for handling method stubs
5788 in the type information.
5790 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
5792 * values.c (baseclass_addr): Run loop from INDEX+1 to
5793 N_BASECLASSES; otherwise, we can still get into a loop.
5794 @@ This should be restructured to use a cleaner search strategy.
5796 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
5798 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
5799 abbreviation "Tt" for tags which have the same name as their
5802 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
5804 * symtab.c (list_symbols): add ability to set breakpoints on all
5805 the functions which match a particular regular expression.
5807 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
5809 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
5810 should print ANSI qualifiers (such as `const' and `volatile').
5811 All callers changed to call with ANSI == 1, except from
5812 `check_method_stub', which uses old-style syntax.
5814 * symseg.h (struct fn_field): Remove unneccessary `args' field.
5815 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
5817 * values.c (check_stub_method): New function.
5819 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
5821 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
5822 * valprint (type_print_base): Ditto.
5824 * symtab.c (gdb_mangle_typename): New function.
5826 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
5828 * breakpoint.c (catch_command): New function. Provides a
5829 mechanism to set breakpoints based on catch clauses.
5830 (disable_catch): Similar, but disables breakpoints on catch
5832 (delete_catch): Similar, but deleted breakpoints on catch clauses.
5834 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
5836 * blockframe.c (blockvector_for_pc): New function.
5837 * blockframe.c (block_for_pc): Changed to call
5838 `blockvector_for_pc' and get the block itself.
5840 * stack.c (catch_info): New function. Prints info about
5841 exceptions which can be caught in the current frame.
5842 * stack.c (print_frame_label_vars): New function. Similar to
5843 `print_frame_local_vars'.
5844 * stack.c (print_block_frame_labels): Prints out labels that are
5845 defined in this frame. These labels are exceptions that can be
5848 * dbxread.c: Updated to handle N_CATCH symtab types.
5850 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
5852 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
5853 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
5854 when printing the type.
5856 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
5858 * valprint.c (val_print): Use `baseclass_addr' to access the
5859 baseclasses pointed to via the derived class object at VALADDR.
5861 * values.c (baseclass_addr): New function. Casts derived pointers
5862 to baseclass pointers taking virtual baseclasses and multiple
5863 inheritance into account.
5865 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5869 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5871 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
5872 exp_valid_block field correctly.
5874 * infrun.c (wait_for_inferior): When checking "don't even think
5875 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
5876 also check step_resume_breakpoint.
5877 Insert breakpoints and continue (not step) if
5878 step_resume_break_address != NULL, even if another_trap.
5879 If trap_expected and we enter sigtramp, then set up a
5881 If trap_expected is set when we hit the step_resume_break,
5883 When calling resume and trap_expected says tell resume to step
5884 (2 places), also check step_resume_break_address.
5886 * infrun.c (wait_for_inferior): Don't set
5887 prev_{pc,sp,func_{start,name}} before calling wait ().
5888 Do set them after exiting loop.
5889 Move their declarations outside functions.
5890 (start_inferior): Initialize them.
5892 Thu May 3 00:15:11 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5894 * infrun.c (wait_for_inferior, after check for trap_expected > 1):
5895 Restore old code which distinguishes between trap_expected and
5896 running_in_shell, just make the latter take any non-TRAP signal,
5899 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
5901 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.
5902 xconfig/3b1 (CC,PINSN_CC): Define.
5904 * xconfig/altos, altos-dep.c: Rename altos-dep.c to altos-xdep.c.

5915 * utils.c: Split #ifdef USG into a USG_UTILS and a QUEUE_MISSING.
5916 xm-88k.h: Define USG_UTILS.
5918 Wed May 2 00:05:33 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)

5921 (printf_command): Add from_tty parameter.
5923 * valprint.c (value_print): Check VALUE_OPTIMIZED_OUT flag.
5925 * value.h: Add optimized_out field and change lazy field to
5926 char. Add macro VALUE_OPTIMIZED_OUT.
5928 * i386-pinsn.c: Change from Eirik Fuller to write to stream directly
5929 instead of stuffing things in buffers (oappend, etc).
5931 * breakpoint.c (bpstat_do_actions): If *BSP is set to NULL by
5932 execute_command, exit both loops.
5934 * Makefile.dist: Don't set TARGET_ARCH. Add .c.o rule.
5936 Tue May 1 17:07:23 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5938 * Makefile.dist (RAPP_OBS, rapp),
5939 rgdb.c, rserial.c, rudp.c, serial.c, udp.c, xdep.h,
5941 m68k-xdep.c, coredep.c: Wrap in #if !defined (RDB).
5943 * valops.c (value_struct_elt), values.c (value_static_field):
5944 Change error messages to remove references to `info methods'.
5946 Tue Apr 24 10:25:10 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5949 infrun.c (start_inferior): Add START_INFERIOR_HOOK.
5950 infcmd.c [SHIFT_INST_REGS]: New code.
5951 findvar.c (read_relative_register_raw_bytes): Return a value.
5952 infcmd.c (do_registers_info): Check value from
5953 read_relative_register_raw_bytes.
5955 * command.c (delete_cmd): Free the struct cmd_list_element(s)
5958 Mon Apr 23 10:42:21 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5961 findvar.c (get_saved_register): New function.
5962 findvar.c: Rewrite code which called find_saved_register to
5963 call get_saved_register instead.
5965 Sun Apr 22 14:47:51 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5967 * valprint.c (val_print): Change error message printed when
5968 the type has TYPE_FLAG_STUB set.
5970 * valprint.c (val_print): Check for TYPE_CODE_UNDEF.
