1 Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com)
3 * coffread.c, coredep.c, i386-xdep.c: install patches for
4 SysV/386 3.2 from Mauro DePalma.
6 Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
8 * core.c (core_file_info), exec.c (exec_file_info): Print file
9 type. Use printf_filtered.
11 * valops.c (value_fetch_lazy): Avoid 0-length fetches.
13 Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
15 * dwarfread.c: Add casts to remove compiler warnings.
17 * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
18 tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
19 tm-sun3.h: Remove locally duplicated code for calling functions
20 in the inferior. The only differences were in the specific trap
21 vectors used and whether or not an fpu was present. These are
22 now handled by appropriate definitions of BPT_VECTOR and
23 HAVE_68881 respectively. Other minor obvious cleanups.
25 * valops.c: Correct a minor misspelling.
27 * utils.c: Remove local BSD/USG hacks that are now in libiberty.
29 * dwarfread.c: Remove prototype for dwarfwarn. Does not work
32 Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
34 * stack.c (frame_command): Always print. Use new
35 frame_select_command to select a frame without printing.
37 * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
39 Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
41 * dwarfread.c: New file for DWARF debugging format support.
43 * elfread.c: New file for ELF object file format support.
45 * procfs.c: New file for SVR4 /proc (process file system) support.
47 * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
50 * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
52 * xm-m68k.h: New file for host machines with m68k cpu.
54 * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
55 Add elfread.o and dwarfread.o to OBS.
57 * symfile.h: Add "elf" to list of supported formats in comment.
59 * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
60 types to gdb, builtin_type_long_double, builtin_type_complex, and
61 builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
62 TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
63 TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
64 TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
65 types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
67 * infrun.c: When using SVR4 /proc interface instead of ptrace(),
68 call proc_set_exec_trap() to setup child to stop at first instruction.
70 * inftarg.c: When using SVR4 /proc interface, call proc_wait()
73 * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
74 supply_fpregset(), and fill_fpregset(), which are machine
75 dependent support routines for SVR4 /proc interface.
77 * utils.c: Add warning_setup() and warning(). Warning() behaves
78 the same as error() except that it returns normally rather than
79 jumping back to command level. Modules that don't want to call
80 warning() for some reason, but want to produce their own warnings,
81 can call warning_setup() to ensure compatibility with the way
82 warning() and error() deal with the terminal.
84 * symtab.c: Make internal errors produce more useful messages.
86 * tm-68k.h: Move code that is duplicated in almost every single
87 m68k based machine's configuration files to this common file.
88 Duplications in the configuration files still need to be removed
91 * infrun.c (child_create_inferior): System V versions must call
92 setpgrp() with no arguments, to comply with prototyping typically
95 * munch: Add support for SVR4 style nm output.
97 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
98 file specific fields from the partial symbol table structure and
99 replace them with a pointer to private data for each different
100 flavor of object file reader to initialize appropriately.
102 Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
104 * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
107 * mipsread.c (fixup_undef_type): New function. If a struct /
108 union / enum is defined in a header file but nowhere else used,
109 (by typedefing, pointer referencing or declaration) the mipsread code
110 builds the complete tree for the structure but leaves its code as
111 TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
112 Guess its type based on the details of the members.
114 Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
116 * infrun.c (wait_for_inferior): Check return value from
119 Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
121 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
122 by my last edit to this routine.
124 Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
126 * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
127 FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
128 the values before putting them into the dummy code. (From Peter
131 Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
133 * configure.in: added ebmon target.
135 Wed Oct 16 22:49:58 1991 John Gilmore (gnu at cygnus.com)
139 * Makefile.in: Roll VERSION to 4.2.
140 * README, TODO, WHATS.NEW: Update.
142 * core.c (core_open): Improve error message for bad file.
143 Pass .reg virtual memory address to fetch_core_registers to help
144 it find the registers in the core-file header.
145 * coredep.c (fetch_core_registers): Take new argument, use it,
146 and pass it to register_addr to locate the block of registers.
147 * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
149 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
150 Sequent N_FN_SEQ like everybody else's N_FN.
152 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
153 * tm-i386v.h: #endif guck.
154 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
155 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
156 * xconfig/tahoe: Add REGEX, which seems to be missing.
158 * coredep.c: Add <sys/types.h> for SCOnix.
159 * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file.
160 * printcmd.c (print_formatted): Flush output before disassembly.
162 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
164 * doc/refcard.tex (sec "Working Files"): consistent metavars and
165 other improvements, due to comments by François Pinard
166 (pinard@iro.umontreal.ca)
168 * doc/gdb.texinfo (appendix "Installing GDB"): changes in
169 configure, and improvenets related to Pinard's refcard comments
171 Tue Oct 15 08:45:12 1991 John Gilmore (gnu at cygnus.com)
173 Changes from Fred Fish:
174 * tm-68k.h (FPI_REGNUM): Add.
175 * infrun.c (child_create_inferior): flush stdout and stderr

178 * inflow.c: Handle TIOCGLTC_BROKEN for Amiga.
181 * values.c (show_convenience): Use printf_filtered.
182 * main.c (define_command): Check result of lookup_command for

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

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

207 generic routines for calling inferior functions.
209 * blockframe.c (inside_main_scope, inside_entry_scope): New.
211 * copying.awk: Filter formfeeds out of copying & warrantee.
212 Make them available as `show copying' and `show warrantee' also.
213 * main.c (print_gnu_advertisement): Advt `show' commands.
215 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)
217 * mach386-xdep.c: Even when cross-compiling, leave in the
218 core-file reading code.
219 * core.c (get_core_registers): Avoid coredump if no .reg section.
221 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
223 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
224 This avoids coredumps under `set print object on' in value_headof
225 (called erroneously by value_from_vtable_info) for `p &struct'
226 or `p *struct'. From Peter Schauer.
228 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
230 * Makefile.in: Roll version to 4.1.2.
231 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
232 size from BFD (but, FIXME, we don't yet read external nlists's and
233 convert them to internal nlists's before handling them -- we still
234 assume they have the same size and alignment.) Use SET_NAMESTRING
236 * exec.c (exec_file_command): Move dead coff-encapsulation code
238 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.

242 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
243 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
245 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
247 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
248 * mips-xdep.c (store_inferior_registers): Don't try to
249 write the (pseudo) FP.
250 * mipsread.c (parse_partial_symbols): Improved algorithm for
251 setting pst->texthigh.
253 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
255 * doc/Makefile: make TEXINPUTS include . everywhere
257 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
259 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
260 vestiges of typevectors, which were for symsegs and are no longer
261 used. (From a question by Eliot Dresselhaus
262 <dresselh@RFT30.nas.nasa.gov>).
264 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
266 * dbxread.c, coffread.c: static-ize functions that were
267 gratuitiously external. (From Fred Fish.)
269 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
271 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
272 until it is large enough.
274 * dbxread.c (read_type): Handle error case slightly better.
275 Make complaint message not C++-specific.
277 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
279 * infrun.c (wait_for_inferior): Fix step/next so that you only
280 stop at the beginning of a new line. This fixes various problems
281 with for loops, nested if-else's and switch statements.
283 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
285 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
286 between symtabs and psymtabs become ordinary error()s.
288 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
289 properly, making "end pc" correct in shared lib psymtabs.
290 (From Guy Harris <guy@auspex.com>.)
292 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
294 * dbxread.c: Enable, but soften, const_vol_complaint.
295 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
296 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
297 should be file-scope, not global.
298 (read_struct_type): Remove ancient multiple-inheritance warning.
299 (read_range_type): Check base type, complain & patch if undefined.
300 * stack.c (frame_info): Demangle the function name in `info stack'.
303 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
305 * eval.c (evaluate_subexp_for_address): Don't use
306 TYPE_POINTER_TYPE directly (it might be zero if this type has
307 never had a pointer created before); use lookup_pointer_type.
308 * symtab.c (lookup_method_type): Arguments were swapped in all
309 callers, so fix it here. I'm amazed this worked at all!
311 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
313 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
314 "bss" rather than "data" symbols, but which still conflict.
317 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
318 * core.c (core_files_info): Shorten output.
319 * exec.c (exec_files_info): Ditto.
320 (build_section_table): Ignore zero-length sections.
321 * language.c, printcmd.c: Lint.
322 * language.h (get_frame_language): Declare.
323 * saber.suppress: update.
324 * stack.c (find_relative_frame): Remove complex code that was

334 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
335 (Reported by Mark Peek <mark@imagen.com>.)
337 * solib.c (solib_map_sections): Relocate all sections, even
338 though only the text section's size is tracked. Mark ld_text
339 for eventual elimination as we generalize to N sections.
341 * infrun.c (wait_for_inferior): Don't check if the PC is in a
342 call_dummy if we were stopped by a random signal that is being
343 passed to the program. This produced wierd results when calling
344 functions in the inferior and signals (e.g. SIGALRM) were in use.
346 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
348 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
349 Bugfix from Paul Eggert <eggert@twinsun.com>.
350 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
351 * valprint.c (print_floating): Print 9 digits for IEEE floats.
354 Mon Sep 23 15:50:07 1991 John Gilmore (gnu at cygnus.com)
356 * Makefile.in: Roll VERSION to 4.1.1.

360 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
364 * Makefile.in (VERSION): Set to 4.1.
365 * language.c (set_language_command): Print useful help message,
366 and restore the language string after giving help.
367 * valprint.c (typedef_print): Print typedef in C or M2.
368 * symtab.c (list_symbols): Use it.
369 * main.c (main): Avoid any output before (gdb) prompt when -q.
370 * language.c (set_language_command): Handle errors by restoring
371 the language string to its current state (fix from A. Beers).
372 * doc/gdbint.texinfo: Roll in information from README. Rearrange
373 "how to install" and "how to print the doc" stuff so it drops
375 * configure.in: Rename rtpc CPU to romp to match config.sub.
376 * README, WHATS.NEW, TODO: Update for gdb-4.1.
378 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
380 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
381 autoloading shared libs, copyright etc on GDB startup, clean up $_
382 and $__ index refs, set/show listsize and related updates to list
383 cmd. New host/target configs.
385 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
387 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
388 from main Makefile.in version definition
389 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
391 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
393 * doc/gdb.texinfo: merge new language-switching and lang-specific
396 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
398 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
399 compilers (which may lack stddef.h).
401 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
403 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
404 N_WARNING are the same except for the N_EXT bit, so just use their
405 values alone, rather than OR-ing them with N_EXT.
407 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
409 * mipsread.c (parse_lines): Deal with negative extended line
412 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
413 global symbol conflicts.
415 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
417 * .gdbinit: Move 'set complaints' to top, so it runs even in
418 case we aren't debugging GDB.
419 * language.c (_initialize_language): Fix type check and range
420 check documentation strings.
421 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
422 language.c can use it. (Though language.c should really not be
423 handling warnings/errors the way it does, FIXME.)
424 * symtab.c (lookup_primitive_type): const lint.
426 Bugfix from Peter Schauer:
427 * source.c (lines_to_list): Make signed, to avoid comparison
428 going unsigned and complaining that -3 is too high for 21 lines.
429 * stack.c (lines_to_list): Ditto.
431 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
433 * Makefile.in (HFILES): Add minimon.h.
434 (VERSION): Roll version number to 4.0.95.
435 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
436 New rules for building distributions. Normal distribution
437 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
438 one level up from here; it calls make-proto-gdb.dir to build a
439 directory `proto-gdb' which is an image of the release. The old
440 `gdb.tar.Z' rule still works too.
441 * config.sub, configure: Roll in latest from ..
443 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
445 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
446 new-target, and new-config chapters; fix minor typos; come closer
447 to usual GNU markup conventions for @file @samp @code @var.
449 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
451 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
452 * mipsread.c (parse_partial_symbols): Enter the name of all
453 structs/unions... into the psymtab so we can access them if the
454 symtab is not read in.
455 * mips-tdep.c: Remove some unneeded #includes.
456 * xconfig/dec3100: Add HAVE_STRSTR.
458 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
460 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
461 * c-exp.y, m2-exp.y: Lint.

463 * valprint.c (val_print_fields): Check for stub type.
464 * mipsread.c (_initialize_mipsread): Avoid using
465 builtin_type_void at initialize time.
466 (mipscoff_symfile_read): use it now.
468 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
470 Merge multiple-language support, and partial Modula-2 support,
471 from Andrew Beers <beers@cs.buffalo.edu>.
473 * i387-tdep.c: New file, consolidates most 80387 support,
474 and eliminates host dependency on double<->extended conversions.
475 * i386-xdep.c, symm-xdep.c: Remove most 387 support.
476 * xconfig/i386{sco,v,v-g,v32,v32-g}: Now need i387-tdep.o.
478 * symfile.c (allocate_symtab): New fn, consolidates the work
479 of allocating and initializing a new struct symtab. Set the
480 language of the symtab based on its filename extension.
481 * symfile.h: Declare it.
482 * mipsread.c (new_symtab): Use it. Minor formatting changes.
483 * dbxread.c (end_symtab): Use it.
485 * mipsread.c (parse_symbol, case stParam and stProc): Add #if 0'd
486 code for saving types of parameters with each function definition.
487 * dbxread.c (define_symbol, function and parameter cases): Ditto.
488 (read_dbx_symtab, case N_DEFD): Ignore.
489 (read_enum_type): Recognize FALSE/TRUE enum as Modula-2 BOOLEAN.
490 (read_range_type): Rename MAX_OF_TYPE to MAX_OF_C_TYPE, etc.
491 #if 0 out its uses, though, since they set a dead value.
492 * coffread.c (end_symtab): Use allocate_symtab.
493 (process_coff_symbol): #if 0'd for functions and params as above.
494 (read_enum_type): Recognize Modula-2 BOOLEAN.

567 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
569 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
570 entries are enclosed herein. Not all of these changes
571 have been merged into the master GDB sources -- check the
572 ChangeLog above here for the merge log.
574 Mon Jun 3 17:05:45 EDT 1991
576 m2-exp.y Created. Tested outside of GDB for a few days. Proper
577 operators were added, C specific operators and tokens
578 removed. yylex() revamped to some extent. Still things
579 missing from the grammar, such as sets.
580 Tested for two weeks in GDB v3.5.
582 Tue Jun 11 17:23:48 EDT 1991
584 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
585 so they are built-in. Sort of a hack.
587 Fri Jun 14 12:53:51 EDT 1991
589 m2-exp.y Added range checking for numeric constants. Any numeric
590 constant is assumed to be of builtin type INTEGER unless:
591 (1) it is octal or hexadecimal, in which case it is a
592 CARDINAL; (2) it is too big to fit into an INTEGER, in
593 which case it is a CARDINAL.
594 eval.c Added simple range checking for +, -, and * on integers.
595 Doesn't work very well for *, since 6 * 1,000,000,000 =
596 1,705,032,704, which fails the simple test of result >=
597 first_operand, no matter in what order the operands are.
599 Tue Jun 18 14:11:30 EDT 1991
601 Broke the parser into parts, one containing the C grammar and the other
602 containing code to be shared by all of the grammars.
604 The following files no longer exist:
609 The following files were added:
611 c-exp.y (The C grammar)
612 m2-exp.y (The Modula-2 grammar)
613 parser-code.c (Code that is shared by the above grammar)
617 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
618 now necessary to use the Bison compiler compiler, since it
619 will generate function/variable prefixes other than yy.
621 Tue Jun 18 16:47:49 EDT 1991
623 symtab.[ch] Added the external variable working_lang, than holds the
624 value of the current working language.
625 Added the ennumerated type language_mode, with the values
626 language_auto and language_manual, the former meaning that
627 GDB sets working_lang as needed, and the latter meaning
628 that the value of working_lang is totally under user
630 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
631 REAL, BOOLEAN and CHAR. Also added the type codes
632 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
633 utils.c Added set_language_command and show_language_command to
634 implement the GDB support commands "set language" and
636 expression.h A number of identifiers were added to the type exp_opcode
637 to facilitate Modula-2 builtin functions, integer
638 division, and array indexing.
640 Wed Jun 19 13:25:58 EDT 1991
642 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
643 if the language specified by working_lang requires the use
644 of strict typing of expressions. Eventually, even this
645 will be able to be changed by the user.
646 Added the macro RANGE_CHECK, which evaluates to non-zero
647 if the language specified by working_lang requires the
648 checking of a value against the domain of its type.
649 Eventually, even this will be able to be changed by the
651 language.[ch] Predicates involving types (simple_type, ordered_type,
652 same_type, integral_type, numeric_type, character_type,
653 boolean_type, float_type) are added. These predicates are
654 based on the current value of working_lang, and are handy
657 Wed Jun 19 15:39:34 EDT 1991
659 eval.c Added the function type_array_rank which computes the rank
661 valarith.c Added the funtion value_bool, which when given a integer
662 value.h value (ie. struct value *) as an argument, it returns a
663 boolean value (ie. struct value *) true if that integer
664 is non-zero, and a boolean value false otherwise.
665 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
666 will print out properly.
668 Wed Jun 19 16:36:34 EDT 1991
670 valops.c Added the function value_capitalize, which returns it
671 value.h argument capitalized if its argument is a lowercase
672 letter, or the argument unchanged if its argument is not a
674 valarith.c Added the function range_check_p, which returns non-zero
675 value.h if its value argument is between the integral bounds upper
677 Added the function range_check_enum_p, which makes sure
678 that its value argument is a valid member of the domain of
680 Added the function range_check_range_p, which makes sure
681 its value argument lies between the upper and lower bounds
682 of its type argument, which must be a ranged type.
683 Added the function check_array_index, which range and type
684 checks an index of an array.
685 Added the function value_multi_subscript, which computes
686 array[idx1,idx2...idxN], given a value array and an array
687 of values representing indicies.
688 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
689 unpack_long to work with TYPE_CODE_BOOL and
692 Wed Jun 19 18:04:08 EDT 1991
694 symtab.c Stored pervasive types in a structure and make
695 lookup_pervasive_type() a lookup function that was based
696 on working_lang. If lookup_pervasive_type() returned
697 non-zero, then that value was returned (a fix, since
698 before it simply wouldn't return the pervasive type.)
699 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
700 non-zero if the language specified by working_lang means
701 "conversion" when it says "cast".
702 valops.c Added the function value_real_cast(), which performs a
703 value.h *cast*, not a *conversion*, which is what value_cast()
704 does when it can. In particular,
705 value_cast(<float_type>,4) = 4.0, while
706 value_real_cast(<float_type>,4) = some mess.
707 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
708 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
709 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
710 and MIN on integral types. *NOTE*: These are currently
711 hardcoded to work only if there are 8 bits per storage
713 eval.c Made logical functions call value_bool to return a
714 properly typed boolean value, based on working_lang.
716 Thu Jun 20 11:55:27 EDT 1991
718 valprint.c Types now print out in a Modula-2 fashion. This works for
719 the cases when the type is printed out step-by-step, that
720 is, it doesn't work when the name of a structured type
721 (which includes the keyword "struct", etc.) is simply
723 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
724 since type specifications in C and Modula-2 are very
725 different. The C printing of a type is very recursive,
726 whereas in Modula-2 it is generally very simple. C has
727 type prefixes and suffixes, which have no real analogue in
728 Modula-2. Maybe type_print() should call a language
729 specific type printer. This is also advantageous if we
730 compile GDB to exclude some of the languages. We'll just
731 leave those functions out.
733 Thu Jun 20 16:57:10 EDT 1991
735 dbxread.c When reading the complete symbol table in (via
736 psymtab_to_symtab()), the number and types of function
737 arguments are added to a function type. define_symbol()
738 calls add_param_to_type() to accomplish this.
739 Assumption: when we come across a function definition
740 (N_FUN symbol with an 'f' or 'F' in the name), its
741 arguments will appear before another function definition.
742 When a function is found, a pointer to its type is placed
743 in the global in_function_type. Changes that
744 add_param_to_type() makes are to this global.
745 valprint.c The type of a function now includes (for Modula-2) the
746 types of its parameters.
747 eval.c Type checking and a check for the proper number of
748 arguments is now done for function calls. Not sure of the
749 impact this has on C++ member function yet.
751 Thu Jun 20 19:58:48 EDT 1991
753 valprint.c Rewrote the type printer. Broke it into two language
754 specific parts, adding the functions type_print_m2() and
756 An unfortunate consequence is this: if you debugging a C
757 program in Modula-2 mode (why?), info types does not work
758 well with regular expressions, since the types are printed
759 out in Modula-2 terminology, but stored in C terminology.
760 language.[ch] Added the functions new_type_last(), type_keyword(), and
761 type_sep() to aid in the printing of typedefs.
762 symtab.c Made the printing of typedefs as language independent as
763 possible through calls to new_type_last(), type_keyword(),
766 Fri Jun 21 11:50:26 EDT 1991
768 dbxread.c Check all incoming ennumerated types. If it looks like
769 Modula-2's BOOLEAN type, then change the type_code of the
770 type to TYPE_CODE_BOOL so we can process it as a boolean
772 valprint.c Replaced some of the 0x%x with calls to sprintf and
773 hexformat() in val_print().
774 language.[ch] Added the function hex_to_string(), which converts its
775 integral argument to a hexadecimal number (format is
776 language based) and returns the result as a string.
778 Mon Jun 24 12:25:07 EDT 1991
780 valprint.c Some functions call type_print_1() directly, instead of
781 value.h using type_print(), so they can specify where (column) to
782 print things. Since type_print() takes care of language
783 dependence, that needs to be called first. Added a
784 parameter depth to type_print() (so it is now like
785 type_print_1). Changed type_print to type_print_at, and
786 made type_print a macro that passes a depth argument of
788 symmisc.c Changed all calls to type_print_1 to calls to
790 Makefile.dist Made it possible to build GDB for a specific set of
791 depend languages. Do this by passing a definition for the macro
792 LANGS to make. LANGS should be a string containing a
793 space-separated list of language names (ie. LANGS="c m2").
794 The default is to build all languages. Note that grammar
795 files must follow the naming convention of <lang>-exp.y.
796 gdb.lang This holds the current value of the LANGS macro. It is
797 examined every time make is called, and is updated if
799 eval.c Added #ifdef _LANG_<lang> to these files.
800 expread.c Still need to add them to dbxread.c and coffread.c.
808 Mon Jun 24 16:33:11 EDT 1991
810 language.[ch] Added the functions hexformat_pre() and
811 hex_to_string_pre(), which take a prefix argument to
812 include in the format string. Thus, hexformat_pre("08") will
813 return "0x08x" (if the working language is language_c).
814 Made hexformat() and hex_to_string() calls to the above
815 with "" as the prefix argument.
817 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
818 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
819 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
820 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
821 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
822 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
823 valprint.c, vax-pinsn.c
825 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
826 calls to hexformat() and hex_to_string(). Format strings without
827 the leading "0x" were ignored.
829 depend Updated to take the above into account.
832 Tue Jun 25 15:27:18 EDT 1991
834 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
835 and type_check_t to keep track of the current state of
836 range and type checking.
837 main.c Added the variables range_mode, range_check, type_mode,
838 and type_check to record the current state of range and
839 type checking. Added initialization code to main().
840 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
844 Tue Jun 25 17:57:08 EDT 1991
846 dbxread.c process_one_symbol() updates the variable (enum language)
847 source_lang based on the extension of the filename
848 contained in the N_SO sybmol that started this symtab.
849 When end_symtab() is called, the value of source_lang is
850 put into the language field.
851 stack.c select_frame() sets working_lang (and possibly type_check
852 and range_check) to the language field of the symtab
853 associated with the frame that is selected if working_mode
854 is language_auto. If working_mode is language_manual, a
855 warning is printed and working_lang is not set.
856 language.c Added the function set_type_range(), which sets the value of
857 type_check and range_check (if their modes call for
858 automatic setting) based on the current value of
859 working_lang. A non-zero argument will cause the current
860 settings to be output.
863 Wed Jun 26 14:51:40 EDT 1991
865 eval.c Added range checks on assignment.
866 m2-exp.y Added the grammar for sets to the language. Currently,
867 these do not do anything except print an error message.
869 Wed Jun 26 17:01:04 EDT 1991
871 m2-exp.y Added the ability for parse_number() to parse negative
872 numbers. A global flag is set upon encountering a unary
873 minus. This was done to make, for example, 1 parse as a
874 CARDINAL, and not as an integer, per Wirth's examples in
875 Programming in Modula-2 ed.4.
876 valprint.c Added support for "set radix 2" by then setting
877 output_format to 't'.
878 eval.c Implemented range checking on subrange types. Added calls
879 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
880 Implemented MIN and MAX for ennumerated types. The
881 minimum value of an ennumerated type is defined by Wirth
882 as the first identifier, and the maximum as the last.
883 m2-exp.y Made octal numbers ending with "B" be characters and those
884 ending with "C" be numbers, per Wirth's book. (p. 34)
886 Thu Jun 27 14:11:52 EDT 1991
888 stack.c select_frame() now only sets working_lang, it does not
889 notify the user. If working_mode is language_manual, then
890 a warning is issued once.
891 main.c At the end of each call to execute_command(), working_lang
892 is checked against the local static (enum language)
893 current. If they differ and working_mode is
894 language_auto, the new settings of language, type and
895 range checking are printed out.
896 stack.c Modified frame_info() to include the language of the
897 current frame in the output of "info frame".
898 language.[ch] Added the function language_str() which returns the name
899 of the current language.
901 Fri Jun 28 15:33:14 EDT 1991
903 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
904 the language. INCL and DECL currently cause an error,
905 since sets are not implemented yet. INC and DEC are
906 implemented as PREINCREMENT/PREDECREMENT with one
907 argument, and as ASSIGN_MODIFY with two arguments.
908 eval.c Added type checking to the above cases.
909 value.h Added not_lval_constant to the lval_type ennumerated type.
910 not_lval_constant means that the value is a constant
911 value; that is 3 or 'a' or TRUE, not as in a constant
912 identifier. This is used to help coerce numbers such as 3
913 to either signed or unsigned numbers.
914 valops.c Added the function value_coerce_constants() which coerces
915 constant integers as following: if one is a constant and
916 the other is not, the constant's type is set to the type
917 of the other argument. If both are constants and one is
918 signed, the other is converted to a signed constant.
920 Sat Jun 29 17:26:29 EDT 1991
922 valarith.c Added a better range checker. It now checks range
923 (successfully) on integral operations [+-] (signed and
924 unsigned) for any C sized type. Still does not work well
926 int_in_size() returns an integer that is coerced to fit into
927 specified number of bytes.
929 Mon Jul 1 13:04:14 EDT 1991
931 language.[ch] Added the function binop_result_type(), which returns the
932 builtin (struct type *) type that would be the result of a
933 binop on the two values V1 and V2.
935 Wed Jul 3 19:22:53 EDT 1991
937 source.c Extended source_info() to include the source language in
938 the output from "info source".
940 Fri Jul 5 13:48:52 EDT 1991
942 utils.c Moved the support functions for the GDB set/show commands
943 dealing with language into language.c.
944 language.c Added the function language_info(), which displays info
945 about the current working language, type and range check
946 settings. Called via the GDB command "info language".
947 Added an initialization routine _initialize_language(),
948 that sets defaults for the language, type and range
949 variables and sets up the new GDB commands.
950 main.c Language setup moved to language.c.
953 Mon Jul 8 10:10:22 EDT 1991
955 valarith.c Debugged the range checker for arithmetic. Still does not
956 work for multiplication very well.
958 Mon Jul 8 12:40:37 EDT 1991
960 language.[ch] Added the function value_true() which returns non-zero if
961 its argument represents a boolean true value.
962 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
963 check the truth of an expression.
965 Thu Jul 11 12:51:34 EDT 1991
967 language.[ch] Added the predicate structured_type(), which returns
968 non-zero if the argument is a structured type.
969 Added the predicate pointer_type(), which returns non-zero
970 if the argument is a pointer type.
971 eval.c Added the ability to do addition and substraction on
972 pointers and integers. This case simply bypasses the
975 Thu Jul 11 14:41:42 EDT 1991
978 Added the symbol N_DEFD (0x4a) which is a definition
979 module dependency that is used by the GNU Modula-2
980 compiler and the linker. It is not important to GDB,
981 except that [dbx|coff|mips]read.c should ignore these
984 Fri Jul 12 16:07:00 EDT 1991
986 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
987 0 in val_print(). Also added statements to the else part
988 to coerce type (argument to val_print) to a pointer type
989 if it is an "array of unspecified length".
990 valops.c Added the function value_m2_string(), which returns a
991 (value) value which is a constant string, whose type is
992 (ARRAY [0..n] OF CHAR). The length field of the type
993 structure is set to zero, so it will be interpreted as an
994 "array of unspecified length".
995 stack.c Moved the language/frame mismatch check to
996 main.c:execute_command().
997 main.c The working language is recorded each time
998 execute_command() is executed. If working lang has
999 changed during its execution, then the new
1000 language/type/range info is printed out for the user. If
1001 the working language does not match the language of the
1002 frame, a warning is issued.
1004 Sat Jul 13 16:16:39 EDT 1991
1006 eval.c Moved all the type-checking stuff for operators to
1007 language.[ch] language.c. This is so we can keep language-specific
1008 stuff (like for what type operators are defined) in
1010 language.[ch] Added the function binop_type_check(), which checks to see
1011 if its two (value) arguments are type-compatible with its
1012 opcode argument. The opcode should represent an operation
1013 involving an operator. Also added the macro function
1014 unop_type_check, which calls binop_type_check with a
1015 NULL second argument.
1016 expprint.c Added Modula-2 operators to the op_print_tab, so info
1017 expression.h break works correctly. Also added "op_string", which
1018 returns the string corresponding to the (enum exp_opcode)
1019 opcode that is its argument.
1022 Sat Jul 13 18:26:18 EDT 1991
1024 coffread.c Added code to record the type of function arguments with
1025 each paricular function. Code is very similar to that
1027 dbxread.c Moved add_param_to_type() to symtab.c
1028 symtab.[ch] Added function add_param_to_type() from dbxread.c
1030 *** NOTE: The above additions have not been tested.
1032 Mon Jul 15 12:50:47 EDT 1991
1034 langauge.[ch] Added the functions type_error and range_error, which work
1035 like error() except if the type/range mode is set to
1036 *_mode_warn, then they do not do a return_to_top_level(),
1037 but merely print a warning.
1038 Also changed [set|show]_[type|range]_command() to support
1039 the new "warn" feature.
1041 Thu Jul 18 17:50:54 EDT 1991
1043 mipsread.c Added code to record the type of function arguments with
1044 each particular function. Code is very similar to that
1047 *** NOTE: The above additions have not been tested.
1049 Fri Jul 19 11:19:10 EDT 1991
1051 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1052 UMIN_OF_SIZE, which when given a size of a numeric type,
1053 return the maximum and minimum value it can hold. UMAX...
1054 and UMIN... return the result for unsigned types.
1055 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1056 struct types. They call above macros.
1057 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1058 avoid a name conlict with the above.
1059 c-exp.y Added range checking on numeric constants in
1060 parse_number() for completeness.
1061 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1062 return 0 if working_lang is not language_c.
1064 Thu Aug 8 14:17:22 EDT 1991
1068 breakpoint.c Documentation strings of some commands changed to
1069 eliminate the references to the C language where
1072 Tue Aug 13 15:48:03 EDT 1991
1074 m2-exp.y Added qualified identifiers to the grammar. The semantics
1075 are slightly different from those of the GDB operator ::
1077 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1078 type_exp, where type_exp is any valid type expression.
1080 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1081 printcmd.c Modified ptype_command() so it actually parses the input
1082 (necessary for type expressions with scope qualifiers).
1083 Added the function ptype_eval() which expects an
1084 expression composed of one OP_TYPE element.
1085 *.[ch] Replaced all occurences of parse_c_expression with
1087 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1089 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1091 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1093 Small fixes from Peter Schauer:
1095 * infrun.c (child_attach): Lint.
1096 * solib.c (find_solib): Handle shared libs version 2.
1098 Small fixes from David Wood:
1100 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1104 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1105 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1107 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1108 chars_per_line is at maximum (user typed `set width 0'). Fix
1109 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1111 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1113 * coredep.c: include ptrace.h where necessary.
1114 * mipsread.c(parse_lines): fix unsigned char problem that was
1115 messing up line numbers on SGI's and possibly other MIPS based
1117 * infrun.c (child_create_inferior): use better test to check
1118 return val from setpgrp().
1119 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1120 for sgi/irix support.
1122 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1124 * mipsread.c (parse_symbol): Put non-static procedures
1125 in the global block.
1127 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1129 Patch together `text_start' and `text_end' for 29K port.
1131 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1132 variables and set them based on the exec file.
1133 * am29k-tdep.c: declare text_start.
1134 * valops.c (call_function_by_hand): declare text_end.
1136 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1137 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1138 because machines that do this will also have to know to
1139 set NEED_TEXT_START_END. Besides, it was a redundant way to
1141 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1142 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1143 NEED_TEXT_START_END.
1145 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1147 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1149 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1150 Pass MUNCH_DEFINE to munch whenever we run it.
1151 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1152 format string; use 0x%x instead.
1153 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1154 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1155 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1156 * inflow.c: Handle `short' process group IDs.
1157 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1158 and check for ptrace errors.
1159 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1160 (coff_symfile_init): Initialize text_bfd_scnum.
1161 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1162 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1163 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1164 Merge target arm case with other "easy" cases. Add target
1165 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1166 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1168 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1169 * munch: Cope with RT/PC putting fns in data segment.
1170 Restore ability to override `nm' by specifying MUNCH_NM.
1171 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1172 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1173 and remote-adapt. Remove encapsulated coff #define's (the
1174 support should go in BFD, and gdb shouldn't know or care).
1175 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1176 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1177 * tm-29k.h: Update BADMAG (though it should go away).
1178 Allow the register definitions to be overridden in another
1179 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1180 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1181 DUMMY_SAVE_GR96, for handling kernel calling conventions
1182 that use GR64+ rather than GR96+.
1183 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1184 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1185 overrides various things.
1187 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1188 child_attach does, making a clean stop in the newly attached
1190 * remote-eb.c: Lint.
1192 * coffread.c: Make coffread independent of any particular
1193 variant of COFF. Avoid #include-ing any particular one except
1194 internalcoff.h. BFD now passes key values for symbol reading
1195 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1196 and the symbol masks and shifts); use them.
1197 Remove obsolete end_of_text_addr.
1199 * exec.c: Remove unused include files.
1201 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1203 * Makefile.in (documentation targets): Pass $(M4).
1204 Bugfix from eggert@twinsun.com (Paul Eggert).
1206 * stack.c (down_silently_command): Check for stack existence.
1208 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1210 * Makefile.in (VERSION): Update to 4.0.3.
1212 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1214 * core.c (core_file_command): Print frame at coredump with
1215 its level number, by calling print_stack_frame.
1216 * frame.h: Add selected_frame_level, print_stack_frame.
1217 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1218 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1219 Change print_sel_frame and print_selected_frame callers to
1222 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1223 * symfile.c (free_named_symtabs): Ditto.
1224 * main.c (main): wrap_here needs an arg.
1225 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1226 (solib_add): Avoid noise.
1227 (solib_create_inferior_hook): Lint.
1228 (sharedlibrary_command): Move dont_repeat to here.
1229 * utils.c (error): Call wrap_here to force buffered output.
1231 Small patches from Peter Schauer:
1233 * coffread.c (start_symtab): Free any existing line_vector before
1235 (read_coff_symtab): Ditto for type_vector.
1237 * source.c (lines_to_list): New variable, replacing function.
1238 (all uses): Use as variable.
1239 (_initialize_source): Add 'set listsize' and 'show listsize'.
1240 * utils.c (lines_to_list): Remove function.
1241 * stack.c (print_frame_info): Use as variable.
1242 * defs.h (lines_to_list): Remove declaration.
1244 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1246 * breakpoint.c (insert_breakpoints): Restore warning about
1247 the program might be running in another process, but only for
1248 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1249 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1251 * utils.c (error): if error_pre_print is set, print the string
1253 * main.c (main, print_gnu_advertisement, print_gdb_version):
1254 Reformat legalese so it always prints, but acts as an "I'm here"
1255 message while symbols are being read. If any errors occur,
1256 print a few newlines to set off the message and start it at the
1257 left margin. Remove mention of "help" command, and don't yak
1258 about symbol reading.
1259 (catch_errors): Error string is now printed first in case of
1261 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1262 suggest the "help" command.
1264 * Makefile.in (VERSION): Set to 4.0.2.
1266 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1268 * .gdbinit: Remove useless "rr" command. Set complaints
1269 to 1 for people debugging gdb.
1271 * breakpoint.c, remote-vx.c: Reword strings printed by
1272 catch_errors callers.
1274 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1276 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1277 (Fix from kenc@viewlogic.com.)
1279 Fix some infrastructure to be able to cope with host and target
1280 machines with different sized basic types (ints, ptrs, etc).
1281 (Idea from pierre@la.tce.com (Pierre Willard).)
1283 * values.c (value_from_longest): Rename from value_from_long.
1284 Handle pointer types as well as integers, so that targets with
1285 different pointer sizes from the host can be accomodated.
1286 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1287 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1288 uses of value_from_long to value_from_longest.
1289 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1290 the correct pointer type to value_from_long{est}.
1292 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1294 * remote-vx.c: Remove obsolete code for calling functions via
1295 vxworks kludge interface (it referenced value_from_long).
1297 * valops.c (value_string): Find malloc with lookup_misc_func, not
1300 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1302 Make writing to files work properly. (Fixes to BFD are also needed.)
1304 * core.c (core_open): Open file ourselves, read or r/w, depending on
1305 write_files. Use bfd_fdopenr.
1306 * gdbcore.h (write_files): New variable.
1307 * exec.c (write_files): Define variable, add set&show for it.
1308 (exec_file_command): Use write_files to open for read or r/write.
1310 Make shared library reading happen automatically. These changes
1311 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1313 * inferior.h (stop_soon_quietly): Add to exported variables.
1314 * infrun.c (child_create_inferior): call solib hook, if defined.
1315 (child_attach): call solib hook, if defined.
1316 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1317 (find_solib): Use lookup_misc_func rather than hand-rolled.
1318 (symbol_add_stub): New stub for catch_errors.
1319 (solib_add): Avoid output if !from_tty. Catch errors rather
1320 than just calling symbol_file_add and bombing.
1321 (solib_create_inferior_hook): Interface with the target process
1322 to let it read and alloc shared libs, then figure out what it did.
1324 * core.c (validate_files): Fix typo, soften warning.
1325 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1327 * utils.c (fputs_demangled): Avoid duplicate printing if
1328 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1330 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1331 (Fix from pierre@la.tce.com (Pierre Willard).)
1333 * main.c (catch_errors): Change argument to a char * from an int,
1334 since a char * can point to a struct full of glop, but an int
1335 is not guaranteed to be able to hold a pointer.
1336 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1337 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1338 * core.c (core_open, solib_add_stub): Adapt.
1339 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1341 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1343 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1344 by adding .NOEXPORT target.
1346 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1350 * Makefile.in (VERSION): Roll to 4.0.
1351 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1353 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1355 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1358 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1361 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1363 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1364 reflect above name change
1366 * WHATS.NEW: correct pointer to refcard.
1368 * doc/gdb.texinfo: update New Features, Installing
1370 * doc/gdbint.texinfo: add short description of configure +template
1372 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1374 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1376 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1378 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1379 tar file, add dependencies for referenced doc files.
1381 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1383 * coffread.c, symfile.c, stack.c: saberized.
1385 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1387 * doc/refcard.tex: permuted Essential Commands sec
1389 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1391 set/show symbol-reloading
1392 default set complaints 0
1394 RET-repeat disabled after prompted long displays
1395 processID (attach) interpretation of 2nd GDB cmdline arg
1397 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1399 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1400 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1401 breakpoint.c, main.c: lint.
1403 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1405 Install new configuration scheme for GDB and friends.
1407 * config.sub: Translate ordinary names to three-part names.
1408 * configure: Use three-part names internally.
1409 * configure.in: Translate three-part names to filenames.
1411 * README, WHATS.NEW: Update for gdb-4.0.
1412 * Makefile.in: Roll VERSION to 3.99.
1414 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1416 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1417 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1418 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1419 to single structures rather than arrays; when passing
1420 their address, use &. This avoids trouble with bdead compilers.
1421 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1422 instead. This avoids portability headaches.
1423 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1425 * source.c (open_source_file): Avoid ANSI const bdeath by
1426 skipping declaration and then casting result value.
1427 * tm-hp300bsd.h: Clarify comment.
1428 * utils.c (strstr): Result is const char *; ANSI bdeath.
1429 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1430 since system include file defines it differently from "defs.h",
1431 though the two are equivalent for our purposes.
1432 * tconfig/hp300bsd: Add m68k-tdep.o.
1434 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1436 * tconfig/sun*4: Remove warnings about system assembler.
1438 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1440 * mcheck.c: Avoid warning about undeclared abort fn.
1441 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1442 it causes recursive calls to error() when used in cleanups.
1443 To do so requires that we make it a function, so we do.
1444 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1445 * utils.c (do_cleanups): Remove the current cleanup from the
1446 chain *before* calling it, in case error() is called from it.
1447 The result won't be pretty, but won't be an infinite loop either.
1449 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1451 * dbxread.c (read_struct_type): Grok anon structs for C++.
1452 (vb_name, vptr_name): Null terminate these strings.
1454 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1456 Minor bug fixes from BSD Net2 gdb:
1458 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1459 returns 0, there is no previous frame.
1460 * breakpoint.c (commands_command): If !from_tty, don't call
1461 input_from_terminal_p().
1462 * dbxread.c (record_misc_function): Speed up slightly.
1463 (compare_psymbols): Ditto.
1464 * infcmd.c (do_registers_info): Take a second argument to
1465 determine whether to print float registers. "info registers"
1466 does not do so anymore. "info all-registers" does, now.
1467 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1469 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1470 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1474 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1475 executing_breakpoint_commands if we are interrupted by error.
1476 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1477 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1478 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1479 catch_errors() so we can setup the frame regardless of whether
1480 the shared libs work.
1481 * ieee-float.c (double_to_ieee_extended): Get exponent from
1482 right place in little-endian systems. From John Carey.
1484 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1486 * main.c: Remove unused terminating_signals and catch_termination().
1487 (long_options): Terminate with a zero element.
1488 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1489 (gdb_readline): Make call-compatible with readline.
1490 (init_signals): Improve comments re vfork vs. signal.
1492 * utils.c (prompt_for_continue): Use new gdb_readline().
1493 If we prompt for continuation, we don't let CR repeat the previous
1494 command, once we get back to a prompt. It's too easy to keep
1495 hitting CR, expecting "--more--" prompts, and have some long
1496 command start repeating on you.
1498 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1500 * blockframe.c (frameless_look_for_prologue): Speed up by
1501 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1502 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1503 Define two variants, one faster.
1504 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1505 and return zero, rather than giving an error.
1506 (setup_arbitrary_frame): Initialize the PC in the new frame.
1507 (skip_prologue): Add a second arg saying whether we're just
1508 checking for a frameless function or not.
1510 * core.c (core_open, core_close, core_xfer_memory): Move
1511 section table pointers and bfd* into the target_ops.
1512 (core_open): Allow errors in shared lib reading, etc.
1513 (core_files_info): Describe shared library sections.
1515 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1516 exec_files_info, set_section_command): Move section table
1517 pointers and bfd* into the target_ops.
1518 (add_to_section_table): Add BFD to section table.
1520 * target.c (target_xfer_memory, target_info): Pass target to
1521 xfer_memory and target_info functions.
1524 * gdbcore.h: Move struct section_table.
1525 * target.h: New home of struct section_table.
1527 * solib.c (solib_add): New argument is the target_ops whose
1528 section list is to be added to, if any. Reallocate the
1529 sections in that target to add any that come from shared libs.
1530 (throughout) so_sections renamed to sections.
1531 (solib_xfer_memory): Deleted.
1532 * tm-sunos.h (SOLIB_ADD): Add target argument.
1533 (SOLIB_XFER_MEMORY): Delete.
1535 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1536 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1537 from target_ops. It's the same on all targets. Add two section
1538 pointers to target_ops.
1540 * stack.c (find_relative_frame): Dump ancient algorithm for
1541 "down", just use handy "next" pointers.
1542 (frame_command): Don't error if there is no stack; let user
1545 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1546 modifies static state in the parent process; new_tty itself
1547 runs in the child and modifies the child's file descriptors
1548 to match the saved static state.
1549 * infrun.c (child_create_inferior): Call new_tty_prefork,
1552 * infptrace.c (child_xfer_memory): Add ignored target arg.
1553 * remote-eb.c (eb_xfer_inferior_memory): ''
1554 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1555 * remote-vx.c (vx_xfer_memory): ''
1556 * remote.c (remote_xfer_memory): ''. Rename from
1557 remote_xfer_inferior_memory.
1559 * main.c (main): Only try to attach "corefile" argument if
1560 it starts with a digit.
1562 * symfile.c (symbol_reloading): New "set/show" variable.
1563 (symbol_file_add): Shorten message about symbol reading.
1564 (add_symbol_file_command): Merge with add_syms_addr_command,
1565 since this should work on all targets now.
1566 (stop_whining): Default to zero, to shut up complaints
1567 about bad symbol tables on many systems.
1568 (free_named_symtabs): Just exit unless symbol_reloading.
1570 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1571 and add comment explaining shared library screw.
1573 * source.c: #if defined => #ifdef.
1575 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1577 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1579 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1581 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1582 (doc/Makefile knows how to make one for local config)
1584 * Makefile.in: use doc/Makefile for doc targets
1586 * doc/Makefile: GDB documentation now has its own Makefile
1587 doc/refcard.tex: renamed from "gdbrc.tex"
1588 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1589 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1592 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1594 * values.c (baseclass_addr): When reading target memory, use the
1595 length of the basetype, not the upper type. We've only malloc'd
1596 enough space for the basetype, leading to errors in free().
1598 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1599 ends up as a function specially, since we know the actual type of
1600 the pointed-to address. This (somewhat) fixes display of
1601 expressions that include misc_function_vector names. Try `cond 1
1602 !strcmp("a","b")' then `i b'.
1604 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1605 The child can be proceeded from inside wait_for_inferior in
1606 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1607 getting skipped in that case.
1609 * expprint.c (print_subexp): Use filtered output, since the
1610 subroutines we call use it, otherwise the output is horribly
1611 mangled, since output of wrappable stuff comes out late.
1613 * Makefile.in: Bump VERSION to 3.98.1
1615 * infrun.c (child_create_process): Use execlp to find the
1616 shell to exec our target program. This requires some fiddling
1617 with `environ' since there is no execlpe().
1619 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1621 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1622 Minor rearrangement of refcard permits two new make targets--
1623 gdbrc.dvi DVI output for refcard, using CM fonts
1624 gdbrc.ps PostScript refcard, using PS fonts
1626 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1630 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1631 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1633 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1635 * doc/gdb.texinfo: last changes for release.
1636 Minor typo and formatting fixes; incorporated most fixes remaining from
1637 filed mail commenting on earlier drafts.
1639 Added warnings: pipes don't work in run command;
1640 conditions are converse of assertions;
1641 step over fn without debug info goes to next fn;
1642 vars may have "wrong" values near fn entrance, exit
1644 Added example from Kingston on printing repeated nonadjacent values
1646 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1647 shell mode for signals
1649 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1650 doesn't sound so much like its parent "Stopping and Continuing"; also
1651 moved entries on continue to top of section, so they don't get lost.
1653 Improved installation directions in appendix, added manual formatting
1656 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1658 * configure.in: Remove xm.h and tm.h even if we aren't linking
1659 new ones, so "./configure sun4; ./configure none" does the right
1660 thing. Assume that alldeps.mak and depend are already built in
1661 srcdir, and avoid running "make" (particularly "make depend",
1662 which involves "gcc") from inside configure. Build Makefile
1663 directly rather than building Makefile.conf first.
1664 * configure: Regenerate with above changes.
1665 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1666 to 3.98. Revise gdb.tar.Z procedure to produce a file
1667 called gdb-$(VERSION).tar.Z but which unpacks into a
1668 directory called "gdb". Move non-source files out of
1669 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1670 (depend): Don't try to do "gcc expread.y".
1671 (expread.o): Update dependencies by hand.
1673 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1676 Fixed a variety of small typos that prevented info from formatting
1677 cleanly; altered too-long heading for GPL Appendix, as discussed
1678 w/RMS; Changed date on cover to July 91.
1680 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1683 (1) Applied some fixes due to comments from Larry Breed (easier ones
1684 through chapsec 5.2)
1685 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1686 it's broken in latest texinfo
1687 (3) Introduced *some* use of [] for optional arguments, where
1688 explanation is not simpler by listing cmd w arg and cmd w/out arg
1689 separately. Still not using @deffn.
1690 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1691 couple of headings are too long. Need patches to texinfo or revision
1694 * Partial update to README (which still needs work for this
1695 release!): (1) use of configure corrected for new script,
1696 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1698 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1700 * symtab.c (lookup_symbol): Don't complain right off about
1701 no debug symbols; use the misc function vector first.
1702 (list_symbols): Use misc function vector to find symbols
1703 that don't have debug info, and print them.
1704 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1705 PC range doesn't match symtab PC range, as it does on the
1706 MIPS because our symtab reading isn't perfect.
1708 * dbxread.c (dbx_symfile_read): Make warning about
1709 "no debug symbols" slightly nicer.
1711 * source.c (select_source_symtab): If "main" symbol exists,
1712 but decode_line_spec can't find line info, don't just return
1713 a zero; try other source symtabs or give an error.
1715 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1716 their low addresses first, then rip through fixing high addrs.
1718 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1719 <runene@ifi.uio.no>.
1720 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1722 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1724 * Minor, mostly mechanical, cleanup of doc subdir for clean
1725 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1726 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1728 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
1730 Mostly MIPS and general symbol-reading fixups.
1732 * doc/gdbint.texinfo: Add documentation on symbol-reading
1735 * mipsread.c: Remove kludges around #include "ecoff.h".
1736 Remove redefinitions of a_magic, etc, no longer used.
1737 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
1738 Fix global overview comments to match symfile.c protocol.
1739 (mipscoff_new_init): Eliminate cur_hdr if we have one.
1740 (mipscoff_symfile_read): Eliminate unused code. Avoid
1741 sorting all the symtabs, when all we have read here is psymtabs.
1742 The symtabs are sorted as they are created anyway. Tell
1743 condense_misc_bunches whether we're mainline.
1744 (psymtab_to_symtab_1): Pass filename when recursing, to make
1745 stack trace more informative.
1746 (parse_partial_symbols): Assume cur_hdr as argument.
1747 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
1748 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
1749 the TYPE_NAME of char *, since that's done in symfile.c.
1750 (free_numargs, parse_symbol, add_symbol, add_block,
1751 shrink_linetable): Declare these fns void.
1752 (upgrade_type): Convert tree of if's to switch. Clean up
1753 bogus "off == 0" handling with a complaint. Avoid setting
1754 field bitpos and bitsize of array with lower and upper bounds.
1755 Check specified bitsize of elements against their actual type's
1756 bitsize, and complain if different. Complain about unknown
1758 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
1759 (psymtab_to_symtab_1): Print names of subsidiary files that
1760 are being read in. FIXME, we read far too many files. This code
1761 is not the problem, the problem is in parse_fdr where the psymtabs
1763 (cross_ref): Result should indicate that we used one aux entry
1764 normally, or two if we encountered a "next" entry. This used
1765 to leave the caller pointing at the wrong aux entry.
1766 (add_symbol): If overflowed cur_block, reallocate it larger,
1767 chase all pointers to it, and complain(), rather than clobber memory.
1768 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
1769 (new_field): Only allocate one field initially, not two.
1770 Pull ++ out of macro argument. Simplify.
1771 (_initialize_mipsread): Avoid initialization of importd
1772 global_psymbols and static_psymbols.
1774 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
1775 to properly set pst->symtab; avoid searching for it.
1776 (symfile_fns): Improve comments, add a FIXME.
1777 * dbxread.c: Update comments to reflect symfile protocol.
1778 (read_ofile_symtab, end_symtab): Return the symtab.
1779 (psymtab_to_symtab_1): Set pst->symtab.
1781 * coffread.c (coff_symfile_read): tell condense_misc_bunches
1782 whether we're mainline.
1784 * symfile.h (sym_fns): Remove unused sym_discard member.
1785 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
1787 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
1788 the environment variable is not.
1789 * infcmd.c (finish_command): Use filtered printfs.
1790 * cplus-dem.c: Add struct tags to a few unnamed structs.
1791 * valops.c (value_coerce_array): Improve comments.
1792 * valprint.c (type_print_varspec_suffix): Print array size only
1793 if greater than zero.
1794 * m88k-tdep.c: Shift some lines left by one space, that had
1795 apparently been trashed at some point.
1796 * TODO: More things to do, a few got done.
1798 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1800 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
1801 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
1803 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
1804 * expread.y, findvar.c, symmisc.c: Ditto.
1805 * printcmd.c (address_info): Update printed forms of LOC_
1806 symbols. Elim LOC_EXTERNAL.
1807 (print_frame_args): Keep track of param stack offsets before
1808 re-looking up to find the local register param is kept in.
1810 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
1811 Further integration of mipsread into gdb. Eliminate unused
1812 routines, duplicate declarations. Handle static symbols in
1813 psymtabs as well as external symbols. When reading symtabs,
1814 insert symbols into the correct block (global, static, or a local
1816 (read_mips_symtab, parse_partial_symbols): Don't pass useless
1818 (mipscoff_symfile_read): Don't call select_source_symtab.
1819 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
1820 rather than SYMBOL_VALUE.
1821 (parse_external): Comment clobbering of top_stack.
1822 (parse_partial_symbols): Update comments. Allocate and parse
1823 static symbols as well as external symbols. FIXME, enum values
1824 are not handled in this pass, but should be. Inline new_psymbol.
1825 Use SYMBOL_VALUE_ADDRESS.
1826 (psymtab_to_symtab_1): Read symbols into global static block
1827 by default (until enter some function's local block context).
1828 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
1829 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
1831 * source.c (select_source_symtab): Select a source symtab
1832 from either the symtabs or, failing that, the psymtabs.
1833 (list_command): Update error message.
1834 (forward_search_command, reverse_search_command): Use getc, not
1835 fgetc, for speed. FIXME, add comment about buffers that die if
1836 overrun by long line.
1838 * values.c (unpack_field_as_long, modify_field): Avoid shifting
1839 by an entire word, which is not portable, if we have a 32-bit
1840 field. (Code in dbxread.c already turns such bitfields, if
1841 aligned, into ordinary ints, but fixing this will help for other
1842 symbol formats and for future changes.)
1843 * core.c (core_open): Handle ANSI const brain death.
1844 * utils.c (vprintf): Fix varargs typo.
1846 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1848 * findvar.c (find_var_value): Handle &function better.
1849 * TODO: Document work needed on &fn and &array.
1850 * printcmd.c (print_address_symbolic): New arg is the prefix
1851 to print if a name is printed.
1852 (print_address_demangle): Honor "set print address" now.
1853 Use new arg above to improve spacing of output.
1854 * valprint.c (val_print): When printing function pointers,
1855 print symbolic form too.
1856 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
1858 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1860 * core.c (memory_error): Reword error msg to mislead less.
1862 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
1864 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
1865 parse_partial_symbols): Use newer BFD internals (external_filehdr
1866 and external_aouthdr), byte-swap the fields that we care about
1867 before using them, and make the file header data local to
1868 read_the_mips_symtab rather than global.
1870 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
1872 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
1873 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
1875 * main.c (command_line_input): Flush stdout and stderr
1876 before every call to readline. This reportedly fixes a bug
1877 that comes up in Sys V running emacs-gdb and/or xxgdb,
1878 when stdin/out are pipes or sockets.
1880 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1882 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
1883 Avoid declaring Makefile dependencies, because GNU Make stupidly
1884 tries to update it if we do.
1886 * coffread.c: Revise for minor changes to bfd internal coff
1889 * configure: If -template= is given a relative path, make it
1890 absolute before recurring in subdirectories.
1892 * configure, configure.in, Makefile.in: Install "configure" script
1893 as replacement for config.gdb.
1894 * config.gdb, Makefile.dist, Makefile.sdir: Remove
1895 * README: Update for configure, mostly. FIXME.
1897 * Add dec3100 as equivalent to littlemips. Indicate in all host &
1898 target config files that they are for the host. When the lines
1899 get copied into the Makefile, this makes it more obvious what's
1902 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1904 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
1905 tabs, which end up in the disassembler output inadvertently.
1907 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1909 Make it compile cleanly in an ANSI GCC2 environment.
1911 * blockframe.c: <stdio.h>
1912 * cplus-dem.c: free takes a void *, ifdef __STDC__
1913 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
1915 * defs.h (alloca): Avoid doing anything if alloca already def'd.
1916 * stddef.h, stdlib.h: Remove these files.
1917 * symtab.c: Avoid declaring qsort, close.
1918 * symfile.c: Avoid declaring close.
1919 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
1920 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
1922 Assorted other changes.
1923 * dbxread.c: include "libaout.h", not "liba.out.h".
1924 * printcmd.c (print_frame_args): Set recurse properly for
1925 indentation of struct and array parameters.
1926 * valops.c (value_cast): Allow cast to void.
1927 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
1928 single_step() in a target-independent fashion.
1929 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
1930 set up to be ready to continue. This makes us target independent.
1931 * infptrace.c (child_resume): Remove call to single_step; now
1932 can single step a SPARC target of any kind.
1934 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1936 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
1937 docn into separate sections---basically chapters, plus two loose
1938 pieces that can be configured to go in different places. This
1939 allows GNU m4 to preprocess the manual without coredumping.
1941 * Makefile.dist: tell TeX where to find texinfo.
1943 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1945 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
1946 the new target "rdl-apps.texinfo" which captures the Makefile
1947 variable that records where to find the Readline libraries.
1949 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
1951 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
1952 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
1953 * defs.h (const, volatile): Only define if not already defined.
1954 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
1956 * README: Update for release 3.95.
1957 * config.gdb: Don't create readline dir in subdir builds.
1958 * main.c: Include with "..." form for non-system include files,
1959 so "gcc -MM" for "make depend" works.
1960 Include readline files with "...h" rather than <readline/...h>.
1961 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
1963 * coffread.c: Undo minor damage done by Rich Pixley. Use
1964 different internal and external representations of COFF
1965 data structures. Use new BFD routines for swapping them in and
1967 * symfile.c (free_named_symtabs): Avoid freeing file names that
1968 are null or empty. Old i960 tools seem to produce files that
1969 claim to have empty names, causing each successive file read
1970 to blow away the previous one.
1971 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
1972 Move deferred_stores to top of file, but don't separate its
1973 #define's from its variable. Add commentary.
1974 * Makefile.dist: Fix Rich damage; undo "configure" changes in
1975 favor of keeping the (working) config.gdb. Move readline
1978 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
1980 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI

1990 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
1991 applied various small fixes due to or inspired by RMS comments
1993 * doc/gdb.texinfo: finished using all RMS comments, save those for
1994 appendices on readline and cmd history (which are in other source
1997 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1999 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2000 chapter 9; (2) documented 'break' command's menu mode for
2001 overloaded names, in response to hgs problem report C++ p-31
2003 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2005 * doc/gdb.texinfo: (1) better introductory example; (2) more
2006 consistent use of @code, @samp, @file, @kbd throughout; small
2007 cleanups to first three nodes; (3) new "Contributors" node;

2009 instructions to "Targets" chapter for generic manuals, while
2010 leaving them up front for manuals specific to specialized
2011 environments; (6) apply fixes from RMS comments through chapter 4.
2013 * pretex.m4: modify explanatory text slightly (and redefine
2014 "regexp") to keep GNU m4 from complaining. (It still crashes

2034 * gdbint.texinfo: added instructions on generating gdb.info* files
2035 locally for release. These are ordinary info
2036 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2037 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2038 to generate these, so we distribute them already formatted.
2040 * gdb.texinfo: included full Info node and menu crud (as generated
2041 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2043 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2044 put in comments-for-future gdb.info target (one day makeinfo will

2058 * mipsread.c: Rather than keeping count of how many symtabs
2059 and psymtabs we have, for sorting purposes, count them when

2087 and memory_remove_breakpoint, no longer used. (Suggestion of
2090 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2091 to make it easier to interface to "configure"'d libraries.
2093 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2095 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as

2487 before returning locals or slocals.
2489 * i386-tdep.c (i386_follow_jump): Do not add data16 to pos in

2521 tm-sun3.h: Define TARGET_SUN3.
2523 * utils.c: Use CPLUS_MARKER not '$'.
2525 * cplus-dem.c: Use CPLUS_MARKER not '$'. If CPLUS_MARKER isn't
2526 defined, define it to '$'.
2528 * arm-opcode.h: New file (same contents as before; it had
2529 just been left out of the distribution for a long time).

2557 * mips-xdep.c (fetch_core_registers): #if 0 out the whole function.
2559 * Move read_memory_nobpt from mem-break.c to breakpoint.c.

2600 New function to give correct error message.
2602 Thu Apr 11 17:19:41 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
2604 * target.h: Add to_doc and target_preopen.
2605 target.c: Add target_preopen and target_command.
2607 (add_target): Call add_cmd and mess with targetlist->doc.
2608 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
2609 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.
2610 Call target_preopen from open routine.

2629 Thu Apr 18 18:08:30 1991 John Gilmore (gnu at cygint.cygnus.com)
2631 * symfile.h (free_named_symtabs): Rename from free_named_symtab.

2633 free_named_symtabs): Move these routines from symmisc.c.
2634 * symmisc.c (same): same.
2635 (free_symtab): Make non-static.
2636 * symtab.h (free_symtab): Declare as exported void fn now.
2637 * dbxread.c (end_symtab, end_psymtab): Change comments.
2638 (initialize_dbxread): Call dbx_new_init() in case the first
2639 command is add-symbols.
2640 * target.c (dummy_target): Permit add_syms_addr_command.
2642 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2644 Permit symbols to be superseded when new symbol files have
2645 been read in, particularly for VxWorks.
2647 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
2648 to the main file, as well as to include files. Also, put global
2649 functions into the global psymtab, to make "i fun" work.
2650 (end_psymtab): Free named symtabs and psymtabs for a file, once a
2651 new psymtab for it has been read.
2652 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
2653 a file, once a new symtab has been read for it.
2654 * mipsread.c: FIXME. We need to do the same for MIPS, but it
2655 looks harder to determine the top-level block before it's been
2656 queued to the psymtab list.
2658 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
2659 If we have wiped out any old symbol tables, clean up at end of
2661 (symbol_file_command): Don't reference symfile_fns if it's zero.
2663 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
2664 defines for the blocks of a blockvector that contain global and
2665 file-static symbols and the first of the smaller scope contours.
2666 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
2667 decode_line_1, make_symbol_completion_list): Use the above.
2668 * coffread.c (end_symtab, patch_opaque_types): Ditto.
2669 * dbxread.c (end_symtab): Ditto.
2670 * expread.y (block): Ditto.
2671 * mipsread.c (throughout): Ditto.
2672 * symmisc.c (free_named_symtabs): Ditto.
2674 * symtab.c (list_symbols): Process the first symbol of the
2675 static psymbols list.
2676 (types_info): Restore this function from its untimely #if 0.
2677 It's not perfect, but it is better than nothing.
2678 (_initialize_symtab): Restore "info types".
2680 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2682 * m68k-stub.c: Remote stub for 680x0's, created from
2683 rem-m68k.shar (which is removed).
2684 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
2685 Remove RCS log stuff now that we use CVS and it blows our diffs.
2687 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2689 * symmisc.c (free_named_symtab): Make it work, in its current
2690 kludgy fashion. Change result to indicate if we blew away bkpts.
2691 * dbxread.c (end_symtab): Accumulate result from
2692 free_named_symtab and print warning if we blew user's state.
2693 * symfile.h: free_named_symtab now returns an int.
2695 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
2697 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
2698 is the first symbol read, even if not mainline.
2699 (dbx_psymtab_to_symtab): symfile might be zero, cope.
2700 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
2701 (set_section_command): New command ("section xxx yyy" -- should
2702 be renamed to "set section xxx yyy" FIXME) which sets the
2703 base address of a section of the exec file, overriding the
2704 virtual address that BFD reports.
2706 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2708 * exec.c: Add add_syms_addr_command to exec_ops, so you can
2709 load symbols at any address while examining an exec file.
2711 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2713 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
2714 for printing the float info is host-dependent, not
2715 target-dependent. FIXME.
2716 * i386-pinsn.c: Move #includes to top, remove useless ones.
2717 * i386-tdep.c: Don't bother including <.../reg.h> since we
2718 don't use it (and it doesn't exist on host systems).
2720 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
2721 Convert negative numbers properly.
2722 (ieee_test): Make numbers really random; fix format arg.
2724 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
2725 * core.c (core_detach): Unpush core_ops, which might not be on
2726 top. We used to just pop the top, which broke things. Don't
2727 need dont_repeat() any more.
2728 (core_file_command): Psst! Don't repeat it.
2729 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
2730 * expprint.c (print_subexp): Avoid switch fallthru on
2731 BINOP_ASSIGN_MODIFY, so we can print += and such.
2732 * frame.h: Fix typo.
2733 * inflow.c (kill_command): After killing inferior, print our
2734 current frame in the core file, if we have one.
2735 (generic_mourn_inferior): When inferior dies, either select
2736 the current frame (in the new target, e.g. core file), or
2737 set both the current and selected frames to NULL.
2739 Changes from Peter Schauer.
2741 * infptrace.c: Avoid <sys/ptrace.h> on USG.
2743 * Make all file names fit in 14 characters (sigh and damn!):
2744 mv hp300hpux-xdep.c hp300ux-xdep.c
2745 mv symmetry-xdep.c symm-xdep.c
2746 mv symmetry-tdep.c symm-tdep.c
2747 mv convex-opcode.h convx-opcode.h
2748 mv tm-vxworks960.h tm-vx960.h
2749 mv tm-vxworks68.h tm-vx68.h
2750 mv Makefile.srcdir Makefile.sdir
2751 mv gdb-int.texinfo gdbint.texinfo
2752 mv remote-sa.m68k.shar rem-m68k.shar
2753 mv remote-multi.shar rem-multi.shar
2754 * Makefile.dist, README, config.gdb, convex-pinsn.c,
2755 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
2756 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
2759 * command.c (user_info_1, user_info): New command for listing
2760 the user-defined commands.
2762 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2764 * dbxread.c (really_free_pendings): Clear file_symbols
2765 and global_symbols after freeing them; otherwise, running
2766 this function twice (if it appears twice on the cleanup
2767 chain), we try to free things twice.
2769 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
2770 based on text_addr (the address of text in core), not on addr (the
2771 offset between text in the .o file and in core). This change
2772 is from Peter Schauer.
2774 * main.c: Define ALL_CLEANUPS as a cast of zero.
2775 (return_to_top_level): Use it.
2776 (main): Do all cleanups after each command run as part
2777 of the gdb startup sequence. Also do all cleanups before
2778 entering the command loop, and every time we exit the command
2779 loop and reenter. Before, the cleanups from the startup sequence
2780 were being left undone until the first error!
2781 (command_loop): Rename do_nothing cleanup to command_loop_marker
2782 so we can see it easily when examining the cleanup chain.
2783 (init_signals): Add another do_nothing for signal handling.
2784 (quit_command): Only try to kill target if it has execution.
2785 Problems in the target stack got us into a state where
2786 inferior_pid was nonzero but none of the targets had execution.
2787 In this state you couldn't exit gdb.
2789 * dbxread.c: Two changes from Peter Schauer.
2790 (echo_command): Fflush output after an echo command.
2791 (show_history): Pass all args to cmd_show_list.
2793 * utils.c (init_malloc): Call mtrace to turn on tracing
2794 if the environment variable MALLOC_TRACE is set to a file name.
2795 * mtrace.c: Add source file which provides a log of every malloc,
2796 free, and realloc to a trace file.
2797 * mtrace.awk: Add source file which analyzes the trace file.
2798 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
2799 (VERSION): Roll to 3.94.3.
2801 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
2802 (check_duplicates): Don't bother with watchpoints.
2803 (set_raw_breakpoint): Comment about danger of this routine.
2804 (watch_command): Parse and eval all args before calling
2807 * solib.c (find_solib): Avoid error in referencing memory to
2808 see if any more shared libraries have been added. This is
2809 particularly useful if the target has terminated. Bug reported
2812 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
2813 in bringing up 3.94.2 on the Sun-3.
2815 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
2816 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
2817 expression (in scope) before reenabling watchpoint.
2818 * signame.c (init_sigs): Add missing declaration of i, fix
2819 sys_siglist declaration.
2820 * source.c (list_command): Fixed range computation to use
2822 * stack.c (backtrace_command): Do not allow command if target has
2823 no stack, print informative error message.
2824 * target.c (target_command): Do not write into command line
2825 because this fails if the target command is used in a user defined
2826 command. [This change was enhanced by gnu to support any-
2827 unique-prefix matching on target names.]
2828 * valops.c (value_struct_elt): Avoid infinite loop on an
2829 erroneous attempt to print the member of function (try p main.p).
2831 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2833 * expread.y (name_no_typename): Avoid reduce/reduce errors
2834 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
2835 Since the GDB parser really doesn't use name_no_typename in a
2836 name-only context, the parser can't tell the diff between
2837 names and numbers here. Avoid allowing a name_no_typename
2838 to be a NAME_OR_*INT to resolve the conflict.
2840 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2842 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
2844 * valprint.c (val_print_fields): bitfield printing didn't handle
2845 byte order. Indirect through a few more fns to cope.
2847 * values.c (modify_field): also cope with byte order.
2849 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2851 Cleanup for release 3.94.2:
2853 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
2854 include files. Roll version to 3.94.2.
2856 * coffread.c (init_stringtab): Read length into unsigned char
2857 array before swapping; don't assume 32-bit longs.
2859 * target.c (target_info): Don't bother with get_sym_file, just use
2860 the symfile global variable.
2861 * symtab.h, symfile.c (get_sym_file): Delete it.
2863 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
2864 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
2865 (read_type): Replace one more error() with complain().
2867 * mipsread.c (parse_partial_symbols): Replace printf with complain.
2869 * i960-tdep.c: Fix copyright attribution.
2871 * config.gdb: Quote all backquotes in doublequotes. You can
2872 quote me on that. BSD 4.4 shell found this one.
2874 * infptrace.c (throughout): The third argument to ptrace is an
2877 * infrun.c (wait_for_inferior): When program has terminated, we
2878 have to call target_terminal_ours before we pop that target off
2879 the stack (e.g. before a call to target_kill or
2880 target_mourn_inferior). This fixes problem where a program
2881 terminates, then GDB stops for (tty output) and you have to type
2882 "fg" to the shell to resume it. FIXME: This code for what to
2883 do after termination really should be in normal_stop instead.
2885 * gdbcore.h (read_memory_check): Change declaration; it changed
2888 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
2889 4.4 prereleases, this avoids a bug in their sgtty compatability
2891 * remote.c: Use terminal.h rather than hand-rolling the same.
2893 * signame.c, signame.h (psignal): Arg is unsigned, not int.
2894 * utils.c (strsave, strstr): Fix arg types.
2895 * valprint.c (val_print): lint
2897 MIPS symbol table support from Per Bothner:
2899 * symfile.c (symtab_fns): Remove initializer table that needs to
2900 be hacked for each new symbol file format supported.
2901 (add_symtab_fns): New function, chains symbol table
2902 handlers into the global list.
2903 (symfile_init): Search this list.
2904 * symfile.h: Add next pointer, declare add_symtab_fns.
2905 * coffread.c (_initialize_coffread): Call add_symtab_fns.
2906 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
2908 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
2909 symbol *). Thus, we no longer need the hack to trash
2910 pst->filename. Good, since that hack confused code in symfile.c!
2912 (reorder_symtabs, destroy_all_symtabs): Removed static
2913 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
2914 Instead, the latter now uses a temporary array (stack-allocated
2915 from an obstack, and then freed).
2917 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
2918 haven't been set in the outermost stBlock of a procedure. This was
2919 a problem with f77 binaries on Ultrix 4.?.
2921 (new_symtab, new_symbol, new_type): Continue changing code to use
2922 obstacks more and otherwise conform to dbxread internal style.
2923 Made the free_code of symtabs be free_linetable (as in dbxread)
2924 instead of free_contents. This implies memory leaks when reading
2925 a new symbol table, until the conversion is finished. Did change
2926 (struct symbol) and (struct type) to be allocated on the
2927 symbol_obstack. Blocks and blockvectors are among the things
2930 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
2931 tested much, but it solved one problem (reported by Meissner), and
2932 cleans up some other things. The problem happened when an
2933 included file contains actual code (functions) and not just
2934 definitions. The mips coff is a little inconvenient there, since
2935 it may cause a procedure to be mapped to the wrong psymtab.
2937 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
2938 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
2939 this will need work for the new core paradigm.
2941 Opcode patches from the net:
2943 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
2944 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
2945 missing altogether - they are added here. From Bruce Bauman.
2946 * mips-opcode.h: The low mask for C0 instructions was too small.
2947 From Garrett Lau. I modified the fix to check the entire 32-bit
2950 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
2953 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2955 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
2957 * dbxread.c (read_type): Pointer subtraction (value_sub in
2958 valarith.c) sometimes failed because the types of the
2959 pointers being subtracted were not identical.
2960 These differed because dbxread.c was allocating pointer types
2961 using dbx_alloc_type+smash_to_pointer_type instead of
2962 lookup_pointer_type. I failed to find a justification for the
2963 former, so I changed it to use the latter. Similarly, I
2964 replaced smash_to_function_type by lookup_function_type,
2965 and smash_to_reference_type by lookup_reference_type.
2967 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
2968 _initialize_mipsread): corresponding changes.
2970 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
2972 * source.c (mod_path): Do tilde_expand on each component of the path,
2973 rather than on the (list of) paths as a whole.
2974 (print_source_lines): Set first_line_listed in addition to
2975 current_source_symtab and current_source_line. If the source was
2976 not findable, after a "dir" command to fix the problem,
2977 a "list" would get the wrong lines.
2979 While I was there... (gnu):
2981 * dbxread.c (read_type): Change error to complaint.
2983 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2985 First attempt at detailed understanding of symbol table memory alloc.
2987 * dbxread.c (dbx_symfile_read): Free our string table if we
2988 aren't the mainline. Free the "info" struct since we're done with
2990 (init_psymbol_list): Free any previously allocated psymbol lists.
2991 (): FIXME: Should realloc-down the psymbol lists when done reading
2992 the main symbol file?
2994 * symmisc.c (free_symtab): Free fullname field too.
2996 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
2997 (REGISTER_ADDR): Make result type unsigned int.
2999 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3000 define REGEX must also define REGEX1 (its dependency).
3002 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3004 * tconfig/i960: No longer works, points you at vxworks960 or
3007 * xgdb.c, XGDB-README: Remove file. Users can get the much
3009 * Makefile.dist: Remove all trace of xgdb.
3011 * breakpoint.c (breakpoint_1): Pass demangle arg to
3012 print_address_symbolic.
3013 (clear_breakpoints): Remove unused function.
3014 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3015 (breakpoint_re_set): Use catch_errors to do them all anyway.
3017 * gdb-int.texinfo (Host versus Target): Add section on what is
3018 a "host" feature versus what is a "target" feature.
3020 * infcmd.c (path_command, path_info): Handle the PATH variable
3021 (object search path) as conveniently as the source search path.
3022 * environ.c (set_in_environ): Set some vars in GDB's environment,
3023 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3024 * source.c (mod_path): New function, from guts of
3025 directory_command, modifies a path. Used by path_command.
3026 (directory_command): Call it.
3027 * defs.h (strsave): Declare.
3029 * utils.c (sevenbit_strings): Add new printing option.
3030 (printchar): Use it.
3031 (strsave): Provide this handy helper routine.
3032 (set_width_command): Rename set_screen_width_command.
3033 (_initialize_utils): "set screen-width" => "set width";
3034 "set screen-height" => "set height"; add sevenbit-strings.
3036 * infcmd.c (do_registers_info): Print floating point registers
3037 in raw hex as well as float format, regardless of whether it is
3038 a "virtual" convertible register.
3039 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3040 regs as a double, just in case it's being used that way.
3041 * values.c (unpack_long): Comment on array/function coercion.
3042 (unpack_double): Argument is in target byte order now. For
3043 integer arguments, just call unpack_long and float the result.
3044 * m68k-tdep.c: include defs.h for "const" handling.
3045 * remote-nindy.c: Use ieee-float stuff.
3046 (nindy_fetch_registers): Unpack double regs to host double, then
3048 (nindy_store_registers): Pack extendeds to host double, flip
3049 around by misusing unpack_double, send as target double.
3051 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3052 zero, as when stopped at the first instruction of a process.
3054 * blockframe.c: Fix filename in comment (param.h => tm.h).
3055 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3056 * tm-68k.h: Fix typos.
3058 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3060 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3062 * coredep.c (fetch_core_registers): Pass end-address of register
3063 section to register_addr as expected. Don't call supply_register
3064 if we'd just pass it garbage.
3066 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3068 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3070 * target.c (push_target, target_info): Cast enums to int for < or
3073 * stack.c (print_frame_info): Identify source file & line
3074 even if we can't print it.
3076 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3078 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3080 Clean up IEEE floating point support.
3082 * ieee-float.h: New file.
3083 * ieee-float.c: Write real routines to convert between host
3084 doubles and various target IEEE extendeds.
3085 * m68k-xdep.c: Eliminate assembler code for extended floats.
3086 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
3087 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3088 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3089 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3090 double_to_ieee_extended.
3091 * i960-tdep.c: Define ext_format_i960.
3092 * m68k-tdep.c: Define ext_format_68881.
3093 * sparc-tdep.c: Define ext_format_sparc, though unused.
3094 * Makefile.dist (HFILES): Add ieee-float.h.
3095 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3098 Obsolete the "coffstrip" program in favor of using BFD's strip.
3100 * nindy-share/coffstrip.c: Remove file.
3101 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3102 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3103 * tconfig/nindy960: Remove reference to coffstrip.o.
3105 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3107 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3109 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3110 * dbxread.c: Remove static symfile_bfd.
3111 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3113 * inftarg.c (child_detach): Pop the child_ops vector if the
3114 detach is successful.
3115 * remote-nindy.c (nindy_create_inferior): Don't push a new
3116 nindy_ops since nindy uses the same one for execution and memory
3118 * core.c (core_ops): Use child_attach and child_create_inferior
3119 rather than default attach and create_inferior functions.
3121 Handle floating point registers in core files.
3123 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3124 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3125 This version untested since BFD doesn't yet support sun3 core
3127 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3128 conventions. Fix comments and style. This version has not
3129 been compiled yet, since we have no HP inhouse.
3130 * core.c (get_core_registers): Look for two sections, ".reg"
3131 and ".reg2", and pass both to fetch_core_registers sequentially.
3133 Revise directory path yet again.
3135 * source.c (forget_cached_source_info): Not static any more.
3136 (init_source_path): New default source path is "$cdir:$cwd".
3137 (dir_command): Handle variable arguments ($cdir, $cwd).
3138 (source_info): Print "Compilation directory" rather than
3139 "Originally compiled in" to remind people of $cdir.
3140 (openp): If the path contains $cwd, use current directory.
3141 (open_source_file): If compilation directory is known, replace
3142 first $cdir in path with the compilation directory.
3143 (print_source_lines): Even if we can't print the lines, set the
3144 current symtab and line for future commands like "info source" or
3145 "breakpoint". Also, error message now contains the file name,
3146 line number, and file access error message.
3147 (_initialize_source): Fix help text to describe changes.
3148 * main.c (cd_command): Forget cached source info when we chdir.
3149 * utils.c (strstr): Add simple implementation.
3151 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3153 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3154 Byte-swap COFF symbol tables if necessary when reading them in.
3155 Use complain() to replace error message in one spot. Needs
3156 corresponding change in bfd/coff-code.h to make some symbol
3157 swapping routines non-static.
3159 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3161 Merge changes from Eirik Fuller, for UTek.

3164 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
3165 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3166 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3167 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,

3169 declarations of errno.
3171 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3173 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3174 <rpc/rpc.h> and <rpc/types.h>.
3176 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3178 * i960-tdep.c (examine_prologue): Add new argument limit,
3179 which stops the scan at the end of the prologue, or at the PC.
3180 This fixes a problem where it walks down into the code for the
3181 user's statements if that code looks like function prologues.
3182 Mark Fox and I have been bouncing this code back and forth, making
3183 small changes to it. Callers changed to match.
3185 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3187 Cleanup for gdb-3.94 release final:
3189 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3190 the .c files from vx-share and nindy-share, from the various
3191 macros, since they are not found via ALLDEPFILES.
3192 (SFILES): Add tm-i960.h.
3193 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3194 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3196 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3197 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
3199 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
3201 * am29k-tdep.c: Add contribution line.
3202 (examine_prologue): Cache information about function prologues in
3203 the misc-function-vector to avoid lots of references over the
3204 serial line while examining instructions.
3206 * core.c (core_close): New function made from cleanup_core.
3208 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3209 remote-vx.c, remote.c, target.c, target.h,
3210 Update target_ops vector to add attach, close, and load entries.
3211 Use add_syms_addr_command, not add_file_addr_command, for
3212 add_file. Break out close routine from existing code.
3214 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3215 they are in an obstack.
3216 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3218 (define_symbol): Add symbol type parameter; change callers;
3219 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3220 it to influence the symbol class on the i960.
3221 (define_symbol): Swap LOC_CONST's into target byte order.
3223 * exec.c (exec_close): New function.
3224 (exec_file_command): Call it.
3226 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3227 Fix byte order of frame pointer.
3228 (read_var_value): Result of 0 if var's value can't be found,
3229 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3230 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3231 (locate_var_value): Use read_var_value and use its lazy address
3232 as the location of the var's value. Lint.
3234 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3237 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3238 obsolete Intel versions in favor of vxgdb versions.
3239 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3240 code dealing with byte order of values, which Intel did in host byte
3241 order rather than gdb-4's target byte order.
3242 (i960_frame_chain_valid): Move to nindy-tdep.c.
3243 (examine_prologue, skip_prologue, frame_find_saved_regs,
3244 frame_args_address, leafproc_return, saved_pc_after_call,
3245 pop_frame): Add vxgdb versions from Mark Fox.
3246 (examine_prologue, frame_struct_result_address): Add code
3247 to deal with the saved value of G13 (struct return address
3249 (frame_args_address): Modify Mark's version to prefer the
3250 saved value over the current value in the topmost frame.
3251 Cache result in the frame info to avoid performance hair in
3253 (print_fault): Add gdb960 code for printing faults.
3254 (_initialize_i960): Actually call check_host.
3256 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3257 add stub routines. FIXME, these currently just return zero!
3259 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3260 (attach_command): Call target_attach, not target_open, now.
3262 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3263 (child_attach): Rename from child_open.
3264 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3265 don't confuse it with a zero step_resume_break_address.
3267 * inftarg.c (child_detach): Eliminate inferior_pid test.
3268 (child_files_info): Clean up message a bit.
3269 (child_ops): Use child_attach, not child_open, to attach.
3271 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3272 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3273 findvar.c to here, since it depends on the contents of the
3274 shadow_contents of breakpoints, but keep if #if 0 since it is
3277 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3280 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3281 (ptype_command, display_command): Eliminate have_inferior_p and
3282 have_core_file_p in favor of target_has_stack or
3283 target_has_execution.
3284 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3285 code for actually finding the values of arguments, though we still
3286 keep track of the maximum stack offset for use in printing unnamed
3287 arguments. Handle missing FRAME_ARGS_ADDRESS.
3289 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3290 (struct nindy_regs): Define registers passed to/from nindy.
3291 (nindy_fetch_registers, nindy_store-registers): Translate between
3292 nindy and GDB formats for the registers.
3293 (dcache_init): Statically allocate the cache, since it was being
3294 allocated by a malloc that was never freed anyway.
3295 (nindy_create_inferior): Error, not core dump, if no exec file.
3296 (nindy_before_main_loop): Use target_load, not target_add_file.
3298 * remote-vx.c (net_load): Specify large timeout for load
3299 requests. Allow user to break out with INTERRUPT.
3300 (net_break): Remove useless code, clean up. Change callers.
3301 (parse-args, skip_white_space, find_white_space): Clean up arg
3302 parsing to cope with quoted strings.
3303 (net_wait, net_quit): Never call error, just return status.
3304 (vx_read_register, vx_write_register): Cleanup status checking.
3305 #ifdef the code based on which CPU we are using (960 or 68k),
3306 FIXME, this should be completely general but it isn't yet.
3307 (vx_xfer_memory, vx_resume): Cleanup status checking.
3308 (vx_run_files_info): Improve message.
3309 (vx_load_command): Renamed from vx_add_file_command. Allow load
3311 (net_ptrace): Remove unused routine.
3312 (vx_wait): Adopt code from vxgdb960 to cope with broken
3313 connections to target machine and prompt to disconnect. Remove
3314 debug printouts. Map some EVENT_'s to SIGnals.
3315 (add_symbol_stub, vx_open): Print names of object files we found,
3316 and "ok" if we read their symbols OK. Clarify output in general.
3317 (vx_attach, vx_detach, vx_kill): Add these commands.
3318 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3319 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3320 "info files" output, and create_inferior, since we already have
3323 * stack.c (frame_info): Replace Frame_unknown with 0.
3324 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3325 (return_command): Pop until the PC matches as well as the FP,
3326 so it works even if the FP is shared with another function,
3327 as in "frameless" or "leaf" procedures.
3329 * symfile.c (load_command): renamed from add_file_target_command.
3330 (add_syms_addr_command): renamed from add_file_addr_command.
3331 (add_syms_command): Stub to call target_add_syms.
3332 (_initialize_symfile): Change command names and descriptions,
3333 add-file => add-syms, and load from alias to its own command.
3335 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3336 maybe_kill_then_create_inferior): Default for attempts to start
3337 a process, if one is already running, is to ask about killing
3338 it and retry if yes.
3339 (upstack_create_inferior): #if-0 it, strata obsolete it.
3340 (push_target, unpush_target, pop_target): to_close() a target
3341 before unstacking it.
3342 (target_info): Renamed from target_files_info.
3343 (_initialize_targets): Rename "i files" as "i target", accessible
3346 * target.h: Improve comments about the target_ vectored routines.
3348 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3349 Convert commenting style to standard GNU style.
3350 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3351 (SKIP_PROLOGUE): No longer a no-op.
3352 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3353 (*_REGNUM): Sort register numbers.
3354 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3355 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3356 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3357 are now 10 byte extendeds, not 8 byte doubles.
3358 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3359 for nindy versus vxworks targets. FIXME, this should possibly go
3360 in the target vector.
3361 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3362 frame_saved_regs and arg pointer with each frame.
3363 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3364 (FRAME_ARGS_ADDRESS): Use cached result.
3365 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3366 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3367 (PRINT_RAMDON_SIGNAL): Call print_fault.
3368 (POP_FRAME): Now works.
3370 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3371 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3372 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3373 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3376 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3377 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3379 * valarith.c (value_subscripted_rvalue): Avoid handling
3380 floats and doubles specially; it gave alignment errors. Lint.
3382 * valops.c (value_of_variable, value_of_this): Error if unknown
3385 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3386 to avoid alignment problems.
3387 (value_print): Handle unknown value address.
3388 (cplus_val_print): Two args are ignored; remove them. Change caller.
3389 (val_print): Use unpack_long rather than pointer-deref.
3392 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3393 to avoid alignment problems.
3394 (value_being_returned): Error if return value unknown.
3395 (set_return_value): Add bogosity warning, FIXME. *
3397 * TODO: A woman's work is never done.
3399 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3400 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3401 Add ieee-float.o to OBS.
3402 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3403 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3404 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3406 Changes to generalize the VxWorks RPC protocol slightly, to handle
3407 i960 as well as 68000.
3409 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3410 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3411 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3412 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3413 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3414 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3415 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3416 so they will move in target byte order rather than network
3417 byte order (happens to be the same).
3419 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3421 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3423 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3426 Add contribution lines to various files, showing where they
3429 * breakpoint.c (break_insn, check_break_insn_size,
3430 read_memory_nobpt): Remove to mem-break.c.
3432 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3435 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3436 entry has bad register number. This change is not
3437 tested in this release, FIXME.
3439 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3442 * value.h: Force value's contents field to be aligned to hold
3443 at least a double or a long long (if supported). This avoids
3444 doing bcopy's in and out of the contents field.
3446 (step_1): Avoid coredump under obscure circumstances when we
3449 * symtab.h (misc_info): Add field to misc function vector for
3450 any kind of cached information the target code desires. AMD
3451 29000 uses this to avoid repeating examine_function_prologue's.
3453 * coffread.c: Lint. Remove static symfile, read_section_header.
3454 core.c (have_core_file_p): Lint: remove.
3455 expprint.c (print_subexp): Lint.
3456 infptrace.c, valops.c, valprint.c: lint.
3458 Roll in changes from vxgdb-5.0.1:
3460 * symtab.h: Comment byte order of each address class. Add
3461 LOC_LOCAL_ARG for frame-relative args (960).
3462 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3463 symtab.c, symmisc.c: ditto.
3465 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3467 * remote.c (remote_resume): Error if resume with a signal.
3469 * symfile.c (prim_record_misc_function): Clear misc_info.
3470 (fill_in_vptr_fieldno): Check stub type of arg.
3472 * valops.c (value_cast): Avoid looking up names of types whose
3473 name we don't know, to prevent coredump. Sun CC produces typedef
3474 rtx and the name of *rtx is zero...
3476 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3478 Roll in changes from final AMD 29000 port (Tiemann).
3480 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3481 for ../include/a.out.encap.h. This might not work now that BFD
3482 is separately compiled. Instead, BFD support for encap will have
3483 to translate machine type 29k into the right COFF_MAGIC.
3485 * infcmd.c: Remove references to inferior_pid that aren't used
3486 in actual ptrace calls; use target_has_execution, etc.
3487 (have_inferior_p): Remove function.
3488 (program_info): Print target info rather than "process number";
3489 avoid gratuitous messages unless from_tty.
3490 (run_stack_dummy, finish_command): Set proceed_to_finish.
3491 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3492 main.c: Lint. Lose have_inferior_p().
3493 inferior.h (have_inferior_p): Remove, lint.
3494 (proceed_to_finish): Add flag to ask that all regs be saved
3495 by normal_stop, for the few commands that need it, speeding up
3496 serial I/O. Add comments to stop_registers.
3498 * remote-eb.c: Remove newline from breakpoint message we grep
3499 for. Never time out when running the user program.
3503 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3505 Roll in changes from vxgdb-5.0.1:
3507 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3508 symbol in its raw form, we are processing an unlinked ".o" file.
3509 See if the target environment has assigned it an address, using
3510 target_lookup_symbol (VxWorks does), and enter it into the symtab
3513 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3514 68k versions for a simpler version that assumes zero FP at bottom.
3515 Fixes bug of truncated stack reports.
3517 * target.h (target_lookup_symbol): Define this routine's args
3518 and result, finally.
3520 * target.c (nosymbol): Default routine for target_lookup_symbol.
3521 (target_default): Default lookup_symbol and call_function too.
3522 (files_info): Only print has_all_memory warning if a non-dummy
3525 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3526 vx_convert_from_virtual): If target does not have floating point,
3527 zero register "values", and avoid doing cross-net conversions.
3528 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3529 (vx_open): Rearrange code that attaches to target and reads
3530 symbols for all loaded modules, to work if some of the modules
3531 are not accessible. Add symbol_stub() and add_symbol_stub()
3532 as callbacks from catch_errors(). Allow connect attempt to be
3533 interrupted painlessly with ^C (FIXME, there are still some bugs
3534 if the interrupt happens during symbol reading.). Print
3535 final message with puts_filtered, since symbol messages are
3540 * main.c (catch_errors): Only print errstring if non-null.
3541 (command_loop): Avoid an ioctl per command to test ISATTY.
3543 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3544 (vx_xfer_memory): Return correct result!
3545 (vx_files_info): Indicate whether target has float or not.
3546 (vx_lookup_symbol): Complain, not error, if target gone.
3547 (vx_open): Print "Connected" msg before disabling immediate-quit.
3548 [FIXME: lookup_symbol and vx_open changes need testing.]
3550 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3551 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3552 contributor lines and update copyrights to 1991.
3554 Changes from an attempted H-PUX host port:
3556 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3557 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3558 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3559 * remote-vx.c: include <sys/time.h> for HPUX.
3560 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3561 "core_file_command" routine to BFD regime. May not work yet.
3563 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3565 * xgdb.c: Replace X10 version with some VJ version.
3566 (FIXME: Its copyright assignment is not on record.)
3567 * xgdb.c: Update include files to X11R4 (Xaw crud).
3568 (xgdb_display_source, create_text_widget): fix call to
3569 get_filename_and_charpos. Rewack source window stuff for X11R4
3570 (gleaned from include files, and "nm's" of binary libraries, since
3571 I had no doc available).
3572 (append_selection, append_selection_word): Disable with FIXME
3573 since R4 changed interface here.
3574 (create_buttons): Add back the old set of buttons.
3575 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3577 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3578 Roll VERSION to 3.94 (not yet final though).
3580 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3582 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3583 obstack_int_grow, obstack_int_grow_fast): Eliminate
3584 cast on left of assignment, which gives MIPS cc fits and is
3587 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3588 F_ALIAS. Use printf, not fprintf, when not passing a file
3590 (compare_opcodes): Check that identical instructions have
3591 identical opcodes, complain otherwise.
3593 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3594 was reported by Roland McGrath.
3595 (unimp): Only match if exactly zero instruction. (Roland)
3596 (branches and traps): Generate all variations of these
3597 instructions with macros, based on a single call that defines
3598 each condition name and its binary representation.
3599 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3601 * valprint.c (val_print_fields): Take, and use, format parameter.
3602 This means that "p/x struct" again prints the elements in the
3603 desired format. Changed callers.
3605 * stack.c (frame_info): Use filtered output, and indicate wrap
3606 points. Remove kludgy formatting designed to avoid line wrap.
3608 * utils.c (wrap_here): If the line is already full (because
3609 we had printed a long indent or long wrapped string), do an
3610 immediate newline-and-indent.
3612 * m68k-pinsn.c (print_insn_arg): Bugfix from
3613 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3614 instruction is incorrectly disassembled as bkpt #8.
3616 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3617 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3618 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3619 and then will dump core (sometimes). I traced it back to an
3620 uninitialized symfile_name in psymtab_to_symtab.
3621 (const_vol_complaint): Add quotes to message.
3622 (define_symbol): Only believe line number if gcc_compiled.
3623 Avoid allocating symbol if we will not return it.
3625 Add target strata support so that newly established targets go
3626 into their right place in the target stack (e.g. a new exec file
3627 doesn't wipe out the ability to access the running process).
3629 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3630 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3631 and initialize it properly in all the targets.
3633 * target.h: Document strata. Change return type of push_target.
3635 * target.c (nomemory): new function for dummy memory access.
3636 (tcomplain): Rename complain, now also used in symfile.c.
3637 (push_target): Push targets within strata. New return value shows
3638 whether new target is on top of stack or not. Always keep dummy
3640 (target_files_info): Ignore dummy target.
3642 * core.c (core_open): Warn user, and skip accessing file, if the
3643 core target is not the topmost target in the stack.
3644 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3647 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3648 target_ops, it doesn't belong there since we have no regs there.
3649 Change name of target from machine => memory to clarify.
3651 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3653 * Freeze version 3.93 for release.
3655 * Makefile.dist: Handle vx-share and nindy-share subdirs
3656 properly when building gdb.tar.Z.
3658 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3659 printed in various places, so I could change just one copy.
3661 * dbxread.c, coffread.c: Change references to bfd->iostream
3662 to cast to FILE *, now that BFD avoids needing types defined
3663 in other header files.
3665 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3667 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3668 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3669 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3670 (actually gcc -Wall).
3672 * dbxread.c: Remove first_global_sym, last_global_sym, since
3673 they are never referenced.
3675 * defs.h (baud_rate): Declare.
3676 main.c: Define it, and add the -b option to set it.
3678 * gdb-int.texinfo: Add text on how to define a new host or target
3679 architecture, prompted by Per Bothner's questions about MIPS
3682 * gdb.texinfo: Document "complaints". Change doc of -q since
3683 gdb no longer prints the copyright and blurb if you specify a file
3684 name to be debugged (just like Emacs). Add doc for Nindy-specific
3685 command line flags for specifying target serial port and such.
3686 Update copyright to 1991.
3688 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3689 has taken over for us the job of ripping up executable files. The
3690 crud caused Per Bothner's port to not compile.
3692 * infrun.c (normal_stop): Avoid printing "Program exited
3693 normally" if we are in batch mode. This allows a GDB which
3694 executes a program on a target system, to behave like a Unix
3695 command (input from stdin, output to stdout, no extraneous
3698 * main.c (main): Allow additional machine-dependent command line
3699 options to be specified with the ADDITIONAL_OPTIONS,
3700 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3701 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3702 processing to occur just before the main loop with
3703 BEFORE_MAIN_LOOP_HOOK.
3704 (main): If a "core file" argument is specified, and it is not a
3705 core file, try it as a process ID to attach.
3706 (symbol_completion_function): Attempt to cope with
3707 "show screen-" TAB, not very successfully. This needs more work,
3709 (batch_file): New function, returns whether we are reading
3710 commands from an interactive tty on stdin, or from somewhere else.
3711 Called by normal_stop since it doesn't get from_tty passed down
3712 to it like many commands do.
3714 * remote-nindy.c: Handle command line options for nindy
3716 (nindy_before_main_loop): Prompt user for tty name if they
3717 don't specify it before getting to the interactive command loop.
3719 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3720 and -r command line options. Also add hook before main loop
3721 to make it easy to specify a tty.
3723 * TODO: More things to do, one done.
3725 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3727 * dbxread.c: Make complaint() calls pass pointer, not struct.
3728 Add complaints about badly formatted C++ type information
3729 (const/volatile indicator, and parse errors resulting in
3730 error_type). Fix C++ virtual member fn comment.
3731 (read_struct_type): Avoid bumping pointer if we got a parse
3732 error; this prevents our walking beyond the end of a string.
3733 Terminate loop on null char as well as semicolon.
3734 (process_one_symbol): Fix the LBRAC fix so that it uses the
3735 last previous SLINE, FUN, or SO record's PC address. C++ debug
3736 symbols did not have SLINE records in a useful order compared
3737 to the LBRAC records.
3738 (define_symbol): Handle "catch" records.
3740 * symtab.c (check_stub_type): Added new complain
3741 `stub_noname_complain' and added a consistency check to
3742 keep the debugger from crashing when finishing from an
3743 exception frame. A real fix will be needed later.
3745 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3747 * infcmd.c (attach_command): Make global.
3749 * Makefile.dist (REMOTE_OBS): Make these compile by default,
3750 but make them easy to comment out. Perhaps later they should
3751 be enabled by what CPU you configure for? FIXME.
3752 (VERSION): Roll to 3.93.
3753 (pinsn.o): Remove rule for obsolete file.
3754 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
3756 Run down a problem that manifested by printing the wrong function
3757 name in stack traces of read_ofile_symtab. Turned out that the
3758 problem was the SunOS 4.1.1 (and previous) C compiler outputs
3759 the LBRAC symbol with an address in the *data* segment, which
3760 blew our binary search through the blocks.
3762 * dbxread.c: Use the complain() facility consistently to bitch
3763 about problems in the symbol file we are reading.
3764 (finish_block): Add code to check the nesting of the blocks;
3765 complain and Procrust them to fit if wrong.
3766 (make_blockvector): Check the order of the blocks, complain
3767 [but don't cope] if wrong.
3768 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
3769 symbols to be sure their PC value is greater than the last SLINE
3770 (line number) symbol we've seen, complaining and adopting the
3771 SLINE PC value if wrong.
3773 * symfile.h (struct complaint, complaint_root, complain,
3774 clear_complaints): Add.
3775 * symfile.c (complain, complaint_root, clear_complaints): Add
3776 facility to deal with non-fatal complaints and to regularize their
3778 (symbol_file_add): Clear complaint counters to allow new complaints.
3779 (initialize_symfile): Add 'set complaints' and 'show complaints'.
3781 * dbxread.c (dbx_symfile_read): Remember the address and size
3782 of the string table for the main symbol file, so we won't read it
3784 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
3785 to avoid reading the string table yet again. Lint.
3786 (throughout): Improve filtered output, including word wrap.
3787 (read_range_type): Improve Bothner's fix to handle other types too.
3789 * utils.c: Improve line wrap implementation. Handle unlimited
3790 width by making chars_per_line unsigned.
3791 (puts_filtered): New, easy, function.
3793 * defs.h (puts_filtered): add.
3795 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
3796 call the identical sort_symtab_syms() in symfile.c instead.
3798 * expread.y: Suggest the `file' command rather than `symbol-file'.
3800 * command.h (enum var_types): Add zinteger for seroable
3802 * command.c (do_setshow_command): Handle var_zinteger. Restructure
3803 nested if's into a switch.
3805 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
3806 we did not stop because of a breakpoint (it must have been for
3807 some other reason, like a "stepi"), so don't print anything.
3809 * symtab.c: Include <sys/types.h> all the time. Now that BFD
3810 doesn't include <sys/types.h>, old SunOS's require it for
3813 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
3815 A test port of gdb-3.92.6 to the Sony NEWS.
3818 Don't normally link in remote- or vx stuff.
3819 Some of it doesn't compile, and it wastes space for 99% of the users.
3820 Remove reference to no-longer-used HAVE_VPRINTF.
3821 Fixed BFD_DEP typo to BFD_DIR.
3823 Fix cast in arg to bfd_h_getlong.
3824 Make char *prefix be const.
3825 Fix how certain range types are mapped into builtin unsigned int types.
3827 Remove 2 #includes. They cause errors (on Sony, at least),
3828 and aren't needed (they wern't in earlier versions).
3830 print_address_symbolic should never demangle labels
3831 (since it prints *assembler-level* labels).
3833 [This was superseded by the change to printcmd below.]
3836 Add some "volatile" return types to avoid warnings.
3837 If MISSING_VPRINTF add vprintf function and not just macro
3838 (since vprintf is used in printcmd.c).
3840 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
3841 (The latter isn't grokked by some PCC-based compilers.)
3843 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
3845 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
3846 * nindy-share/coffstrip.c
3847 Added some forward declarations (otherwise, gcc complains
3848 about implicit extern redefined as static).
3850 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3852 Changes inspired by Per Bothner:
3853 * printcmd.c (print_address_symbolic): Take additional parameter
3854 specifying whether to demangle.
3855 (print_address): Pass in asm_demangle to control demangling.
3856 (print_address_demangle): New fn, takes explicit arg to control
3858 * utils.c: Add new vars demangle and asm_demangle, and let them
3860 (fputs_demangled): If !demangle, just print the argument.
3861 (fprint_symbol): If !demangle, just print raw symbol.
3862 * valprint.c (val_print): Call print_address_demangle rather than
3863 print_address, to cause demangling to depend on the global
3864 rather than assembler-level demangling setting.
3865 * WHATS.NEW, gdb.texinfo: Document.
3867 * main.c (show_command): Show all settings if no arg.
3868 (initialize_main): Make "info set" the same as naked "show".
3869 * command.c (cmd_show_list): Handle prefix commands in the
3870 list, and print the name of the setting as well as its English
3871 description and value.
3873 Allow gdb functions to specify where a line should wrap if it
3874 exceeds the size of a terminal line. Use it to make the output
3876 * utils.c (set_screen_width_command): New fn, mallocs a buffer
3877 of the right size when screen width changes.
3878 (set_screensize_command, screensize_info): Remove #if 0'd fns.
3879 (wrap_here): New fn, indicates a point in the output where we
3880 should wrap the line rather than just letting it overflow at a
3882 (fputs_filtered): Implement wrapping.
3883 (n_spaces): New fn, returns a pointer to N spaces.
3884 (print_spaces_filtered): Use n_spaces.
3885 * defs.h (n_spaces): Declare.
3886 * stack.c (print_frame_info): Wrap with 4-space indent after
3887 fn name and before filename and line number.
3888 * printcmd.c (print_frame_args): Wrap with 4-space indent
3889 before each argument name is printed.
3890 * valprint.c (value_print): Wrap with no indentation before
3892 (val_print_fields): Wrap with indentation relative to nesting
3893 level before each field name.
3894 (val_print): Wrap with nesting indentation before array elements.
3895 * command.c (do_setshow_command): Avoid extra newlines,
3896 wrap with 4-space indent around values printed, end with period.
3897 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
3899 * breakpoint.c (breakpoint_1): Implement addressprint for
3900 "info breakpoints" display. Change file name and line number
3901 format to " at file:nnn" rather than " (file line nnn)".
3902 * gdb.texinfo: Document.
3905 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3907 Frozen for gdb-3.92.6 release.
3909 README, WHATS.NEW: Update for 3.92.6 release.
3911 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
3912 coffread.o from configs since it is now built by default.
3913 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
3914 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
3915 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
3916 from configs since it is now built by default.
3918 Makefile.dist: Update for release 3.92.6. Handle files that
3919 have been moved to ../include, ../getopt, or ../bfd. Add
3920 saber.suppress and tests directory. Add config.status to
3921 the release (it will say "none").
3923 coredep.c: Minor formatting fixes.
3925 These changes were made in early December but only checked in now:
3926 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
3927 nindy-share/nindy.c: lint
3928 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
3929 register values coming back from the target; we store values
3930 in target byte order everywhere.
3932 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
3934 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
3936 * valprint.c (cplus_val_print, val_print_fields): New functions,
3937 which print C++ objects. They conspire to avoid printing a
3938 virtual base class more than once, following all the twists and
3939 turns of C++ virtual base rules.
3940 (val_print): Call the above rather than do it by hand.
3942 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
3943 symbol file, not for added files like shared libs. This really
3944 needs to be generalized to a timestamp per file.
3946 * core.c (cleanup_core): Avoid coredump if no core file.
3948 * config.gdb: Accept -host or -target in place of +host or
3951 * coffread.c (find_linenos): Avoid desupported BFD interface
3952 to line numbers. We still read them manually rather than using
3953 BFD's "generic" features.
3955 * gdbrc.tex, threecol.tex: Add GDB reference card and its
3957 Makefile.dist: Add refcard to OTHERS list for creating tar files.
3959 * Makefile.dist: Eliminate use of $< in explicit targets.
3961 * readline/Makefile: Use $< rather than $*.c, which does not
3962 include the VPATH in GNU Make.
3964 * tconfig/i960-bout, tconfig/i960-coff: These are identical
3965 copies of tconfig/i960, added for global configuration
3966 compatability. All i960 versions can read both coff and b.out.
3968 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
3969 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
3972 * TODO: Think of more things to do.
3974 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
3976 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
3977 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
3978 64-bit float conversion.
3980 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
3981 equivalent to sun?os4 so global config works.
3983 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
3985 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
3987 * main.c: Only declare linesize once; declare pagesize not at
3988 all, since it is never used.
3989 (main): Clear newly allocated line before it is used.
3991 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
3993 Further stabilization for the Intel 960.
3995 * Makefile.dist: Parameterize the location of the "include"
3996 and "bfd" directories, as well as "getopt". Add symfile.c.
3997 Link in both dbxread and coffread. Fix up "make depend" to
3998 rewack the locations of include, bfd, and getopt in its output.
4000 * README: Document moving include files, improve some of
4003 * coffread.c: Move common code out to symfile.c. Change
4004 symbol_file_command style interface to use new *_symfile_init
4005 and *_symfile_read interface under BFD. Use BFD internal
4006 info to locate line table, symbols, etc.
4008 * core.c (core_fetch_registers): Rename to get_core_registers
4009 to avoid confusion with fetch_core_registers.
4010 (register_addr): Move to coredep.c, which is already machine
4011 dependent. This leaves core.c pretty clean of dependencies.
4013 * coredep.c (register_addr): Accept this routine from core.c.
4015 * dbxread.c: Move common code (with coffread.c, etc) into new
4016 symfile.c. Each psymtab now contains a pointer to the
4017 format-dependent function that knows how to read it in. Make
4019 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4020 (process_one_symbol): Add code to complain about a "compiler bug
4021 we muzzle here", if we actually see it.
4023 * eval.c (evaluate_subexp): Insert missing "break" statements
4024 in code that determines whether a variable is an lvalue in
4025 memory, register, or whatever. I detected this via a compiler
4026 bug in which it *almost* mashed out the whole switch statement.
4028 * gdb-int.texinfo: Add minor sections on configuring gdb for
4029 release, and about the README file.
4031 * infcmd.c (registers_info): Fix formatting somewhat. Still
4032 not as pretty as before, but it handles byte swapping.
4034 * remote-nindy.c: If data cache routines are interrupted while
4035 waiting for the remote end, be sure that any uninitialized cache
4036 blocks are on the free list, not on the valid list!
4038 * symfile.h: Flesh out this header file with all the various
4039 routines and variables that have been merged in from dbxread.c
4040 coffread.c, and symtab.c to symfile.c.
4042 * symfile.c: New file, containing code common to dbxread.c,
4043 coffread.c, and some code from symtab.c. All generic code for
4044 reading symbol files should be in here now.
4045 (unrecord_misc_function): Remove unused function.
4047 * symtab.h: Remove file-reading things to symfile.h.
4049 * symtab.c: Remove file-reading things to symfile.c.
4051 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4052 to decode i960 fault types.
4054 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4055 target.c: Change type of the "resume" function from int to void,
4056 since its result was never used.
4058 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4060 * main.c: Replace "stupid" with "caution"; you now "set caution
4063 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4065 * infcmd.c (do_registers_info): Call val_print to deal with the
4066 byte order of the registers being printed. FIXME, this makes
4067 the formatting of the output uglier.
4069 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4070 defined, call it for signals the debugger doesn't itself use.
4071 The i960 uses this for more detailed fault information.
4073 * remote.c (remote_open): If arg is null, print help rather than
4076 * sparc-xdep.c (register_valid): Avoid declaring size, since
4077 various modules will think of various sizes depending on the
4078 architecture of their tm-file. FIXME, we need protection against
4079 actually entering one of those modules, which would clobber
4080 storage if not for the target architecture compiled into gdb.
4082 * stack.c (up_command, down_command): Always print the frame
4084 (up_silently_command, down_silently_command): New commands
4087 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4089 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4090 more parameters than it used to.
4092 * findvar.c (registers): Increase slop to 256 bytes, which should
4093 protect us against even most RISC machines with large register
4095 (locate_var_value): Move declaration inside related ifdef.
4097 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4098 throughout, to avoid throwing away buffered input from the board.
4099 (nindy_wait): Supply_register takes addr_of_value, not value.
4100 (i960_print_fault): Renamed from i80960_fault.
4101 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4102 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4104 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4105 we can set the PC in the call to proceed(). Unpush nindy_ops
4106 before pushing it on top, to avoid message to user. Eliminate
4107 commentary from Unix machines that just misleads here.
4108 (reset_command): Fix error message to suggest target command.
4110 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4112 Release 3.92.5 as frozen.
4114 Stabilize the merged release...with help from lint, Saber C,
4117 Everywhere: Add include files needed to declare return types
4118 of functions called.
4120 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4122 * breakpoint.h: Add undeclared breakpoint functions, and some
4123 functions for display handling since I couldn't think of a better
4126 * breakpoint.c (insert_breakpoints): Make code for disabling
4127 shared library bkpts more likely to work. It's used when we
4128 rerun a program and stop before the shared library has been
4130 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4131 cast from pointer, so it squeezes through catch_errors.
4132 (bpstat_stop_status): Fix logic broken some time ago. We now
4133 always create a bpstat if the stop address matches a breakpoint,
4134 even if we don't stop there -- just like the old code used to do
4135 before I got my fingers into it (sigh).
4136 (breakpoint_1): Print "ignore count" after "stop only if"
4137 condition, since that's how it actually works.
4138 (mention): Handle watchpoints as well as breakpoints.
4139 (watch_command): use set_raw_breakpoint and mention to do most
4140 of the work (and initialize all the fields!). Only pass one
4141 arg to parse_c_expression, since that's all it takes.
4143 * command.c (not_just_help_class_command): Rename arg to args
4144 since we ignore "unused argument" warnings on vars named "args".
4145 inflow.c (child_terminal_info): ditto.
4146 infptrace.c (kill_inferior): ditto
4147 main.c (catch_errors, version_info, quit_command, pwd_command,
4148 source_command, dump_me_command, editing_info,
4149 set_history_size_command, set_history, show_history,
4151 stack.c (locals_info): ditto
4152 target.c (target_files_info): ditto
4153 valprint.c (set_input_radix, set_output_radix): ditto
4155 * core.c: Remove old variables for handling core and exec file
4156 sections (data_start, data_end, stack_start, stack_end,
4157 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4158 text_end, exec_data_start, exec_data_end, text_offset,
4159 exec_data_offset, data_offset, stack_offset). They're
4160 superseded the more general build_section_table and
4162 (get_exec_file): Mention the `file' command.
4163 (read_memory_check): Rename to memory_error, and only call it
4164 in the case of an actual error.
4165 (read_memory, write_memory): call memory_error.
4166 (core_fetch_registers): Register section name is ".reg".
4168 coredep.c: Remove a bunch of crud now that all this file does
4169 is pull the registers out of a core file.
4170 (fetch_core_registers): Rewrite to actually work, I hope.
4172 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4173 Replace index() with strchr(). Remove all the pre-BFD macro
4174 definitions for accessing the symbol file.
4175 (struct dbx_symfile_info): Encapsulate the information that
4176 dbx_symfile_init needs to pass to dbx_symfile_read in this
4179 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4180 dbx_symfile_discard): Rearrange symbol file reading to divide
4181 the format-specific part from the format-independent part,
4182 leaving the format-independent part such as file name expansion
4183 and opening in symtab.c. This replaces
4184 partial_symbol_file_open and partial_symbol_file_read.
4185 Symbol_file_read, add_file, add_file_target_command,
4186 add_file_addr_command move to symtab.c. Pass an explicit
4187 "mainline" flag for when reading the main symbol table, rather
4188 than relying on the offset address to be zero or nonzero.
4190 (dbx_symfile_read): Don't allow void *'s to be printed as
4192 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4193 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4194 macro" debug version really work.
4195 (read_dbx_symtab): Remove unref'd parameter inclink.
4196 Avoid swapping N_SLINE symbols, for speed.
4197 Merge N_TEXT!N_EXT case with the other external symbol
4198 definitions' case. Add comments.
4199 (start_psymtab): Allocate the symfile name in the psymtab on
4200 the psymbol_obstack, rather than using the caller's storage.
4201 (end_psymtab): Only allocate a dependencies list if there are
4203 (psymtab_to_symtab_2): Use BFD when reopening file to read
4204 its symbols for real.
4205 (read_struct_type): Add FIXME comments where it needs work
4207 (read_huge_number): Add FIXME about overflows.
4208 (read_range_type): Add FIXME about comparing a long to 1<<32.
4210 * coffread.c: Minor changes to move things closer to the new
4211 regime with symtab.c and dbxread.c Major work is still needed
4214 * exec.c (exec_file_command): Remove old variables (see core.c
4216 (xfer_memory): If memory transfer is right at the end of a
4217 section, don't lose.
4219 * findvar.c (get_saved_register): If value is in a real
4220 register, LVAL is lval_register, not lval_memory.
4222 frame.h: Declare print_sel_frame and record_selected_frame.
4224 gdb-int.texinfo: New file, for GDB internals documentation.
4225 Very simple, unformatted doc of cleanups is there for now.
4227 gdbcore.h: Remove obsolete variables that described a.out
4228 section addresses and offsets. (See core.c above.)
4229 Declare fetch_core_registers and registers_fetched.
4231 getopt.c: Declare char *alloca(); even on SPARC.
4233 infcmd.c (run_command): Call target_kill rather than
4235 (step_command, next_command, stepi_command, nexti_command):
4236 Declare from_tty parameter even though we don't use it.
4237 (run_stack_dummy): argument BUFFER is a char array, not
4238 a pointer to REGISTER_TYPE.
4239 (finish_command): using_struct_return needed a value *,
4240 not a struct symbol *.
4242 * infptrace.c (child_xfer_memory): To avoid dependency on
4243 where sections are in memory, try PT_WRITE_D and if that fails,
4244 try PT_WRITE_I. Most Unixes don't care which you use.
4246 * infrun.c (step_resume_break_shadow): Change to array to
4247 match other breakpoint shadow storage.
4248 (clear_proceed_status): Pass address of bpstat to
4249 bpstat_clear, not the bpstat itself.
4250 (child_create_inferior): FIXME comment about if the child
4252 (start_inferior): Remove old function.
4253 (child_open): Use target_kill rather than kill_inferior.
4254 (wait_for_inferior): Ditto.
4255 (insert_step_breakpoint, remote_step_breakpoint): Use
4256 new step_resume_break_shadow.
4258 * inftarg.c (child_wait): If all child processes die,
4259 pretend that the one being waited for exited with signal 42.
4261 * main.c (command_line_input): When scanning for comments,
4262 don't coredump on unclosed quotes.
4263 (quit_command): Use target_kill rther than kill_inferior.
4264 (_initialize_main): Rename class_user from "user" to
4267 * printcmd.c (print_command_1): Initialize "fmt" if no format
4268 is specified by the user.
4269 (print_frame_args): Only add to args_printed if we are
4270 actually fetching args from the stack (avoiding undefined
4272 (_initialize_printcmd): Remove bogus \{ from string.
4274 * remote-eb.c (eb_open): Avoid coredump on no argument.
4276 * remote-nindy.c: Bring out of Intel environment into new
4277 target environment. Remove all conditional compilation on
4278 I80960. Massive hacking throughout.
4279 (nindy_xfer_inferior_memory): New routine stolen from
4281 (nindy_create_inferior): New routine pieced together, probably
4282 not quite working yet.
4283 (nindy_ops): New target_ops struct for nindy.
4285 * remote-vx.c: Use write_memory rather than target_write_memory
4286 to get error checking.
4287 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4289 (vx_create_inferior): Use target_terminal_ours...
4291 * signame.c (_initialize_signame): Always initialize, since
4292 we need the table for things other than psignal.
4294 * solib.c (solib_add): Use symbol_file_add, not add_file.
4295 (solib_address): Return boolean result rather than struct
4296 pointer which nobody else knows the type of.
4298 * sparc-tdep.c, valops.c: Use write_memory rather than
4299 target_write_memory, to get error checking.
4301 * stack.c (locals_info, catch_info, args_info,
4302 get_selected_block, frame_command, up_command): Use
4303 target_has_stack, rather than have_inferior_p or
4306 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4308 * symfile.h: New file, defining the interface between the
4309 generic and object-file-specific symbol reading code.
4311 * symtab.c: Move generic symbol-reading interface to symtab.c,
4312 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4313 table to map BFD targets to symbol-reading modules in GDB.
4314 Change index to strchr.
4315 (lookup_struct_elt_type): Use error() rather than hand-made
4316 simulations thereof.
4317 (lookup_partial_symbol): Speedup slightly when length == 0.
4318 (symbol_file_add): New function.
4319 (symbol_file_command): Call it.
4320 (symfile_open, symfile_init): New function.
4321 (add_file_target_command, add_file_addr_command): moved from
4324 * target.c (target_command): use target_kill.
4326 * target.h (target_files_info): Don't declare, never called
4329 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4330 files to determine stack end address.
4332 * valarith.c (value_x_binop, value_x_unop): Change error message
4333 to be more useful. Pass proper argument to value_struct_elt.
4335 * valops.c (value_assign): FIXME comment that long long
4336 bitfields will break here.
4338 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4339 Update `make saber_gdb' to work better.
4341 * TODO: A woman's work is never done.
4343 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4344 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4345 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4346 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4347 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4348 valops.c, valprint.c, exec.c: Lint.
4351 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4353 Continuing Intel 960 port merge of GDB.
4355 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4356 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4357 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4358 Wack over "make depend" so it handles files in subdirectories
4359 vx-share, nindy-share, bfd, and in the current directory.
4361 * blockframe.c (get_prev_frame_info): Remove fatal error
4362 if stack not defined.
4364 * core.c (core_open, core_detach): New functions that handle
4365 the old "core-file" command as "target core" and "detach" instead.
4366 (core_file_command): Call them.
4367 (core_xfer_memory): Use common routine xfer_memory.
4369 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4370 dbxread now uses bfd for everything but symbol reading itself.
4371 BFD internals are used to drag out the relevant file offsets.
4372 (partial_symbol_file_open): Change args all around for BFD.
4374 * symtab.c: Rename "value" to "val" everywhere, so we can
4376 (symbol_file_command): New command, moved from dbxread.c
4377 and coffread.c. It uses BFD to read the file, then vectors
4378 based on its type, to dbx or coff symbol readers.
4379 * symtab.h: Extern a few vars for symbol_file_command.
4381 * target.h: Breakpoint takes a char * save area, not a char **.
4383 * valprint.c (val_print): When unpacking bitfields, offset
4384 the address in gdb of the value, if it is declared with a shorter
4385 type. Remove the last "runtime kludge test" of host byte order.
4387 * utils.c: Remove old my_bfd_read routine.
4389 * stack.c (frame_info): Use target_has_stack. Print program counter
4390 register's actual name rather than "pc", since it's called the
4391 "ip" (instruction pointer) on the i960 (sigh).
4393 * target.c (target_command): Add command for selecting a target
4394 type and calling its open routine. This is used for initiating
4395 communication with a particular target, in a generic way.
4397 * tm-i960.h: Update for modern gdb. Remove semicolons from
4398 various macros. Handle reading struct return convention, and
4399 error-out attempts to return structs with the "return" command.
4400 Be sure gdb doesn't think we know how to call functions in the
4403 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4404 to i960_xxx in lower case.
4405 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4406 not being defined yet.

4409 wait_for_inferior during open.
4410 (remote_xfer_inferior_memory): Return length written rather
4413 * remote-vx.c (target_command -> vx_open): Use new generic
4415 * remote-eb.c, inftarg.c, exec.c: ditto.
4417 * infrun.c: Fix comments.
4418 (attach_program -> child_open): Use new generic target command.
4419 (wait_for_inferior): Clear saved register values before target_wait,
4420 so target_wait can set some of them if convenient.
4422 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4423 Return success indicator, not void.
4424 (child_xfer_memory): Avoid fetching initial word if we'll
4425 overwrite it anyway.
4427 * infcmd.c (attach_command): Use new generic target open routine.
4428 (_initialize_infcmd): Update doc on attach and detach commands.
4429 (do_registers_info): Merge in a byte-order problem as a FIXME
4432 * findvar.c (find_saved_register): Avoid problem in current frame.

4448 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4450 Merge Intel 960 port of gdb, continuing...
4452 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4453 symbol_file_command): Pass from_tty arg to hush 'em up.
4455 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4456 Add magic numbers for 960 COFF format.
4458 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)

4481 Fri Apr 20 13:47:15 PDT 1990
4484 Thu Apr 19 09:54:28 PDT 1990
4485 Add 'reset' command.
4487 Wed Apr 18 09:48:07 PDT 1990
4488 After opening remote tty, wait for 1 second to go by without input
4489 from it before trying to talk to NINDY (fixes problems with the
4490 Heurikon HK80/V960E).
4492 Mon Apr 4 16:33:05 PDT 1990
4493 Some output was not being suppressed in 'batch' mode.
4495 Thu Mar 22 15:31:11 PST 1990
4496 Ask user if old symbol table should be deleted when new file is
4499 Allow user to run a program downloaded before gdb960 was brought up.
4501 Correct "exec-file" help message for i80960 context.

4528 Added 960CA disassembly support.
4530 To simplify maintenance:
4531 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4533 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4534 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4535 - made disassembly interface identical to that in gdmp960.
4539 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4541 * target.h: Allow targets to stack. Add target_has_memory,
4542 _registers, etc. Restructure memory access and "info files"
4543 to walk the target stack.
4544 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4545 target.c: Change tables to match target.h.
4546 * inflow.c (child_mourn_inferior): pop child_ops.
4547 (generic_mourn_inferior): Use new has_stack flag.

4549 * inftarg.c (child_files_info): New "info files" regime.
4550 * remote-eb.c: New memory regime, new info files.
4551 * remote-vx.c: New memory regime, new info files. Now use
4552 separate targets for VxWorks attachment to machine, and
4553 actually running a process under VxWorks, since one has
4554 stack & execution & regs and the other doesn't.
4555 * remote.c: New memory regime, new info files.
4556 * sparc-xdep.c (fetch_core-registers): New memory regime.
4557 * target.c: New routines and support for stacked targets,
4558 new memory regime, new info files regime.
4561 Generalize section handling for an arbitrary number of sections,
4562 including use of the new BFD (binary file) library.
4563 * gdbcore.h: Add struct section_table.
4564 * exec.c (build_section_table): Iterate all sections and
4565 record what gdb needs to know about them.
4566 (exec_command): Use it.
4567 (exec_xfer_memory): Use the table.
4568 (exec_files_info): Print the table.
4569 * core.c (core_file_command, core_xfer_memory, core_files_info):
4571 * source.c (find_source_lines): Use bfd_get_mtime.
4572 * dbxread.c: Quick changes to make it compile with new BFD.
4573 * utils.c (error): Avoid using bfd_error in generic routines.
4575 * core.c (core_fetch_registers): Get from the ".regs" section of
4577 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4579 * inferior.h (attach_flag): Export.
4580 * infcmd.c (run_command): use new target_create_inferior.
4581 * infrun.c (child_create_inferior): Don't return result.
4582 * Makefile.dist (VERSION): 3.91.4.
4584 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
4586 * breakpoint.c (bpstat_num): Handle breakpoints which have
4587 since been deleted, such as temporary breakpoints.
4588 infcmd.c (program_info): ditto.
4590 * core.c (core_file_command): Display the frame where the core
4595 * remote-vx.c (target_command): Merge in target command from
4596 targ-vx.c. A few other cleanups.
4598 * TODO, Projects: Lots more stuff to do...
4600 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4602 Massive changes to wall off the remote-debugging interface
4603 behind a function vector. The port to handle VxWorks targets
4604 is also part of this.
4606 All files: Replace references to renamed functions,
4607 remove references to remote_debugging, remove references to
4608 have_include_file, have_core_file in favor of target_has_stack,
4609 target_has_memory, etc.
4611 * Modularize the breakpoint interface.
4612 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4613 a breakpoint instruction.
4614 breakpoint.c: struct breakpoint's shadow_contents now sized as
4616 (insert_breakpoints): Vector to target to install breakpoints.
4617 (remove_breakpoints): Vector to target here too.
4618 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4619 sparc-tdep.c (single_step): Use new breakpoint interface for
4620 the single-step breakpoints.
4621 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4622 New file, contains routines to insert and remove breakpoints by
4623 reading out the old contents and later replacing them. This is
4624 how ptrace breakpoints work, and many remote systems as well.
4626 * tm-vxworks68.h: New config file, overrides a few things for
4627 Wind River's preferences.
4629 * target.h: New file, for transfer vector used to talk to the
4630 inferior (child, attached, core, exec, remote, etc). All accesses
4631 to the thing being debugged should come through these vectors.
4632 target.c: New file, routines to handle transfer vector.
4633 (various files): Add transfer vectors XXX_ops for the various
4634 targets and pseudo-targets (core files, etc) we support.
4636 * breakpoint.c (bpstat_stop_status): Further explorations of
4637 watchpoints and why things don't work all the time.
4638 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4640 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4641 the local gdbinit if it doesn't already have it.
4643 * core.c (core_ops): add and install.
4644 Allow core debugging without exec file.
4646 * dbxread.c (free_and_init_header_files): Merge two fns.
4647 (end_symtab): Free named symbol table when a new version comes in.
4648 (read_dbx_symtab): Relocate all kinds of symbols with base
4649 address. First step toward handling different text, data, bss
4651 (add_file_addr_command): Renamed add_file_command.
4652 (add_file_command): Vector to remote handler.
4653 Add "load" as an alias for "add-file" command.
4655 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4656 non-returning functions.
4658 * exec.c: Add exec_ops, and push it as a target when an exec
4661 * infcmd.c (run_command): Pass executable file name and arg list
4662 separately when starting an inferior. Permit "run" when no exec
4663 file is specified, for VxWorks.
4664 (detach_command): Move to child_detach in inftarg.c.
4666 * inftarg.c: New file. Unix-child-specific routines, and the
4667 child_ops structure.
4669 * inferior.h (registers): Export "registers" as the way for
4670 target dependent register handlers to find gdb's local copy of
4671 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4672 since it is now used by places that want wait_for_inferior to
4673 handle the grunge but want to see every trap from the inferior.
4675 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4676 Eliminate remote_debugging hooks in terminal handling.
4678 * infrun.c: Replace start_inferior with child_create_inferior.
4679 Move all the hair of Unix shells and ptrace idiosyncracies into
4680 child_create_inferior, so remote handlers don't have to deal.
4681 Remove running_in_shell. Rename stop_after_attach to
4682 stop_soon_quietly, and use it in a few other places where we want
4683 to just call wait_for_inferior and get control back on the first
4684 trap. trap_expected now never takes a value > 1.
4685 (init_wait_for_inferior): Initialize static vars when a new
4688 main.c (gdbinit): Add new hook for .gdbinit file name, let
4689 it be overridden by config files as GDBINIT_FILENAME.
4690 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4691 Both of these are used for VxWorks gdb.
4693 mcheck.c: rename include file "gmalloc.c" to avoid problems
4694 with system include file "malloc.c".
4696 param-no-tm.h: New include file, same as param.h but does not
4697 include the default "tm.h" file. This is used in files where
4698 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4700 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4702 remote-vx.c: New file, VxWorks remote debugging support. Uses
4703 RPC routines that are shared with the target system, in directory
4706 remote.c: Vectorize remote interface.
4708 source.c: Globalize source_path, and make an alias "l" for "list"
4709 since we now have the "load" command.
4711 sparc-xdep.c: Use new param-no-tm.h.
4713 symmisc.c (free_named_symtab): Add new function from Wind River.
4714 However, ifdef it out for now while we think about what it should
4717 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4719 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4720 non-Unix-children handle this with their own code in the target
4723 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4724 source and target lists. Add vx-share to default list of include
4725 directories. Add new files to src and target lists: mem-break,
4726 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4727 ${srcdir} versions of munch and createtags are used.
4729 * valops.c (find_function_addr): Split out of call_function.
4730 (call_function_by_hand): Rename call_function; this function
4731 calls functions in the target by laboriously patching the target
4732 word-by-word with the right stack, args, regs, etc.
4735 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
4737 Handle AMD 29000 a bit better.
4739 * remote-eb.c (readchar): Mask received char log to make it readable.
4740 (remote_start): Pass arguments down to executing program.
4741 Make startaddr unsigned.
4742 infrun.c (start_inferior): Accept args, pass them to
4744 infcmd.c (run_command): Pass args down to start_inferior.
4746 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
4747 the target object file format.
4748 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
4750 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
4751 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
4753 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
4755 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
4756 * TODO: We did a few things, we have more to do though.

4764 (sparc_frame_find_saved_regs): Simplify and fix what we find.
4765 (sparc_push_dummy_frame): Simplify and fix what we push.
4766 (sparc_pop_frame): Slightly more hair here, deciding whether
4767 we are restoring a saved PC or returning to a return address in %i7.
4768 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
4770 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
4771 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
4772 * obstack.h (chunkfun): ditto.
4773 * defs.h (xmalloc, xrealloc): ditto
4775 * utils.c (quit): Grab the terminal from the child if necessary.
4777 * inflow.c (term_status_command): Rename to term_info, change
4780 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
4781 (is_delayed_branch): Speed up.
4782 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
4783 Still missing some float ops, and needs testing.
4785 * Support for input and output radixes other than base 10
4786 * defs.h (input_radix, output_radix): Declare.
4787 * expread.y (yyparse, parse_number): Handle changes of input
4788 radix, and ambiguous names-or-numbers in radixes >10.
4789 * printcmd.c (print_scalar_formatted): Print formatted hex
4790 numbers in varying column widths.
4791 * valprint.c (val_print): Use output_format to print scalar ints.
4792 (set_input_radix, set_output_radix, set_radix): Create.
4793 (set_output_radix): Set output_format from output_radix.
4794 (_initialize_valprint): add `set radix' but leave the others off.
4796 * main.c (execute_command): Let stupid questions be turned off.
4797 (_initialize_main): Handle "set stupidity", etc.
4799 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
4800 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
4802 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
4804 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
4805 bfd stuff is still screwed up, but with some manual work, it
4808 * breakpoint.c (bpstat_do_actions): Start over if a command
4809 proceeds the inferior, since the inferior will have stopped and
4810 will need to have its new stop-actions taken care of.
4812 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
4813 compiler fits, simplify it.
4815 * gdb.texinfo (directory command): Doc new dir command.
4816 source.c (directory_command): "dir" now puts things on the front
4817 of the path, moves dups up front, and handles multiple names
4818 on the command line, inserting each one in order. It also
4819 blows away cached line and full_filename info.
4821 * stack.c (backtrace_command): Skip "more stack frames follow"
4824 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
4825 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
4826 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
4827 The only odd one was Gould NP1, which had defined vprintf to
4830 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
4831 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
4832 variable, inspect_it.
4833 valprint.c (print_string, val_print): Use the global inspect_it
4834 to indicate whether to print in Epoch style or normal style.
4836 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
4838 * printcmd.c (call_command): add an alias for the "print" command
4839 which runs expressions and doesn't print the result if void.
4840 (print_command_1): implement it.
4842 * command.c: Remove #if 0'd code. Initialize all the fields
4843 in add_cmd (). Rename do_nothing_command to
4844 not_just_help_class_command, and make it externally visible.
4845 command.h: add user_commands to struct.
4846 * main.c (define_command): Don't overload c->function with a char
4847 string as well as a function pointer.
4849 * eval.c (evaluate_subexp): Reinstall tiemann changes to
4850 calling convention of value_struct_elt () that got dropped in
4853 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
4854 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
4856 * tm-sparc.h (POP_FRAME): replace some constants with defines.
4858 * sparc-xdep.c (store_inferior_registers): defer stores to regs
4859 until a good time (e.g. when we are about to run the child),
4860 saving ptrace calls.
4861 * infrun.c (proceed): handle DO_DEFERRED_STORES.
4862 * tm-sparc.h: define DO_DEFERRED_STORES.
4864 * sparc-xdep.c (store_inferior_registers): when storing float
4865 registers, don't store stack regs too. When storing the SP,
4866 however, DO store the stack regs too. This fixes a bug in which
4867 the dummy frame is not recognized when a call_function finishes,
4868 because its frame pointer (in the stack regs) was never
4870 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
4871 even though we don't know how to read them from an inferior.
4872 valops.c (call_function): Comment about storing SP.
4874 * infrun.c (save_inferior_status): Save away the original bpstat
4875 chain so it can be restored later. Install the copied version for
4876 use by whoever saved the status. It will be blow away by
4877 restore_inferior_status, and the original chain restored. This is
4878 important for people who have pointers into the original.
4880 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
4881 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
4882 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
4885 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
4887 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
4888 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
4889 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
4891 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
4893 * Merge Mike Tiemann's multiple inheritance changes from Sun.
4894 Store the baseclasses in a type struct starting from array element
4895 0 rather than from the unusual array element 1.
4897 dbxread.c: the above.
4898 (virtual_context): Add
4899 Read new debug information about which virtual function table
4900 a virtual function is from, and store it in fn_field.fcontext.
4902 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
4903 TYPE_FN_FIELD_STATIC_P.
4905 symtab.c: the above.
4906 valops.c: the above. Handle pointer casts of object *'s.
4907 (search_struct_method): Add.
4908 (value_struct_elt): First arg is now a pointer to a value, and is
4911 valprint.c: the above.
4912 values.c (value_virtual_fn_field): Add type arg. Handle
4913 offsetting to the proper object when calling virtual fns.
4915 (baseclass_addr): Add valuep arg.
4917 * README: Document the current state of BFD config (missing).
4918 * TODO, ChangeLog, Makefile.dist: Roll version.
4919 * WHATS.NEW: Add summary of changes since 3.5.
4921 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
4923 * dbxread.c (read_struct_type): Clear bit vectors whenever
4925 symtab.c (B_CLRALL): define.
4927 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
4928 using == rather than =. Huh... This fixes the dreaded problem
4929 wherein builtin_type_int becomes TYPE_CODE_FLT.
4931 * core.c (info_files): Show the inferior pid.
4933 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
4934 already knows how to look in the source directory.
4936 * Remove psymtab hair from many places. Remove duplicated code
4937 for searching symbol tables. Hide psymtabs from most places.
4938 Make it fast to get from a psymtab to its symtab.
4940 blockframe.c (blockvector_for_pc): Remove psymtab hair.
4941 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4942 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4943 dbxread.c: export psymtab_to_symtab, make it work if called N times.
4944 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
4945 new symtab completely. New psymtabs get symtab pointer
4946 initialized to zero. Remove MI warning printf.
4947 symtab.h: Comments. Add psymtab to symtab pointer.
4948 (PSYMTAB_TO_SYMTAB): New macro.
4949 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
4950 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
4952 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
4954 (print_frame_info): Avoid special-casing symbols that have not yet
4957 * source.c (open_source_file): Quick path if we have already
4958 located the source file by its full name.
4960 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
4961 find_pc_psymtab. When a name is found in the misc function
4962 vector, search the symbol table for its mangled name, not the
4963 name that the user typed.
4965 * bfd.h: Fix missing comment terminators, make #endifs match.
4967 * valarith.c (value_less): Handle unsigned int comparisons.
4968 Add FIXME about pointer compares, which assume host and target
4969 pointers are the same.
4971 * command.c (do_nothing_command): lint
4972 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
4973 fix comments on debug symbol format for visibility. Actually set
4974 visibility of symbols.
4975 main.c (echo_command): lint; use <readline/history.h>.
4976 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
4977 obstack.h (_obstack_blank): Rearrange pointer math to avoid
4978 pointing past end of allocated memory; saber complains.
4979 obstack.h: Declare the external functions that we use.
4980 valarith.h: use <string.h>
4981 solib.c (solib_add): lint.
4983 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
4985 * main.c (initialize_main): Default info_verbose to off, now that
4986 symbol reading is fast.
4987 (quit_command): Avoid clobbering exec_bfd while quitting.
4989 * Initial BFD (binary file diddling library) merger:
4990 coffread.c: Change AOUTHDR to struct exe_hdr.
4992 core.c: initialize initialized data at compile time.
4993 (core_file_command): Move from coredep.c, convert to bfd.
4994 (xfer_core_file): Convert to bfd.
4995 exec.c (exec_file_command): use bfd routines.
4997 mips-tdep.c: Remove exec_file_command and friends.
5000 * coredep.c: (fetch_core_registers) Convert core_file_command to
5001 fetch_core_registers.
5002 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5004 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5005 (my_bfd_read): More bogosity, which I don't think we call.
5006 (program_name): Remove this atrocity asap!
5008 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5011 values.c: allocate_repeat_value was not clearing the
5012 optimized_out field.
5013 (value_static_field): minor stylistic fix (wrong macro was used).
5014 valops.c (value_struct_elt_for_address): didn't work for C++
5017 * signame.c (_initialize_signame): Initialize signal names once.
5019 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5020 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5021 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5023 * remote-eb.c: Support user-settable baud rates on the serial port.
5025 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5027 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5029 * tconfig/sun3os4: Remove warning about native assembler,
5030 since it also occurs in the xconfig file.
5032 * findvar.c (registers): Allocate some slop after `registers'
5033 to prevent stray accesses from trashing the next variable.
5035 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5036 on the sun-3, by changing the #ifdef from `sun3' (which is not
5037 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5038 vars, which happened to follow `registers' in the executable.
5040 * readline/history.c (history_search): Heed gcc-2's advice
5041 and parenthesize && inside ||).
5043 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5044 tm-29k.c: Insert FSF copyright headers.
5046 * remote-eb.c: Better comments.
5048 * Makefile.dist: Update to 3.91.6.
5049 * TODO: note PREPARE_TO_STORE problem.
5051 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5053 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5055 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5057 * infrun.c (wait_for_inferior, at end): Don't set up
5058 prev_* if the inferior no longer exists.
5060 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5061 CANNOT_EXECUTE_STACK.
5062 valops.c (call_function): Use it.
5064 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5066 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5067 infrun.c (wait_for_inferior, 2 places): Use it.
5069 * values.c (value_being_returned): Only use
5070 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5072 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5073 right thing for remote-eb.c.
5075 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5076 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5078 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5079 (FRAME_FIND_SAVED_REGS).
5081 * findvar.c ({fetch,store}_registers): Check for
5082 REMOTE_{FETCH_STORE}_REGISTER macro.
5084 * findvar.c (get_saved_register): Add argument lval and
5085 change meaning of argument addr.
5086 findvar.c: Change calls to get_saved_register to reflect
5087 new calling convention.
5088 valops.c (value_assign): Use get_saved_register instead of
5089 find_saved_register.
5091 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5093 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5094 an (uninitialized) pointer to one. Use "&" when passing it
5097 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5099 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5102 * coffread.c (symbol_file_command): Put semicolon after
5104 Put safe_to_init_tdesc_context in #if defined (TDESC).
5105 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5106 coffread.c: #include <sys/stat.h>.
5107 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5108 Add missing ')' in check for "lc%" and friends. Remove
5110 Declare read_one_sym() at top of file.
5111 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5112 MC68WRMAGIC can have the same value without causing a duplicate
5115 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5117 * Allow a Makefile to be built without building the
5118 tm and xm file links that screw up builds in subdirectories.
5119 This is done with `config.gdb none', then you can do things
5120 like `make gdb.tar.Z'.
5121 * tconfig/none: Config file for no target system
5122 * xconfig/none: Config file for no host system
5123 * config.gdb: If no TM or XM files are called out by the
5124 host or target file, don't make links for them.
5126 * cplus-dem.c: Add documentation.
5128 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5129 simple error, so the user's gdb doesn't crash due to some object
5130 file problem (e.g. somebody is rebuilding the file out from under
5133 * printcmd.c (print_address_symbolic): demangle the symbol.
5135 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5136 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5137 (alldeps.mak): sort and uniq all results from this; duplicates
5138 hose gdb.tar.Z link building. Remove RCS files from
5139 tconfig and xconfig. Add config files for sun386. Add
5140 a few odd files to OTHERS and HFILES.
5142 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5144 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5145 Roll version number to 3.91.5. Make lint work in bindir.
5147 * README: Document cross-debugging and new file structure.
5149 * blockframe.c: Lint. Include "value.h" to declare read_register.
5150 (find_pc_partial_function): remove duplicate line.
5152 * command.h: Lint. Declare error_no_arg and dont_repeat.
5154 * tm-news.h: Remove inadvertently duplicated stuff.
5156 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5157 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5159 * config.gdb: Allow `config.gdb host target' form. Clean
5160 up previous change that printed bogus messages when you just said
5163 * core.c: #include "command.h" for lint.
5166 * main.c: Remove some casts of enums. Lint.
5173 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5175 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5176 read it from memory. This will allow us to save ptrace calls
5177 eventually. Changed caller single_step too.
5179 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5180 that we aren't going to use, saving many ptrace calls, especially
5181 when watchpointing or single stepping. Use some #define's for
5183 (store_inferior_registers): Ditto.
5184 (core_file_command): Use some #define's for constants.
5186 * tm-sparc.h: Add #define's for some register numbers, so we
5187 can eliminate the use of random constants in sparc-xdep.c.
5189 * stack.c (frame_command, print_frame_info, up_command,
5190 down_command) Remove frame_changed, since it
5191 causes a bug and doesn't seem to do anything useful. In some
5192 places it was used as a flag, in others as a stack level (?).
5194 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5195 default is to use the portable (vprintf) version rather than the
5197 * xm-news.h (MISSING_VPRINTF): Add.
5199 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5201 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5203 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5204 about linking debugged programs -Bstatic in the sun?os4 config
5205 files in tconfig and xconfig subdirectories.
5207 * main.c (main): Remove unreached exit(0) now that we exit
5210 * Create TODO file for online bug list. There are too many
5211 "little" bugs to keep track of on paper.
5213 * Change Projects file to refer to bug-gdb@cygnus.com
5214 rather than kingdon@ai.
5216 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5218 * Makefile.dist (VERSION): 3.91.4 now.
5220 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5221 (condense_misc_bunches): Add sanity check that misc_count is
5222 the same as the number of symbols in the bunch.
5224 * coffread.c: rename init_misc_bunches. Pass an argument
5225 to condense_misc_bunches (a zero).
5227 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5228 every time we are called; don't rely on our caller to do it.
5229 (add_file): Remove call to init_misc_bunches.
5231 * mipsread.c: Only warn, don't error, if unknown symbol types.
5232 This keeps an old gdb from falling on its face if it sees newly
5233 extended symbol info. Rename init_misc_bunches.
5235 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5237 * Merge in changes from Per Bothner for DECstations and other
5238 MIPS stuff. The rest is Bothner speaking:
5240 The next message is a merger of Alessando Forin's mips port with
5241 mine. I've tried to use my good if biased judgment to get
5242 the best of both. It *does* need testing.
5244 Some of the changes are general, *not* mips-specific.
5247 Didn't believe in little-endian bit order.
5248 There are still inconsistencies about whether flags
5249 like BITS_BIG_ENDIAN are integer (#if ...) or
5250 boolean (#ifdef ...). I tried to paper over them.
5252 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5253 Moved some misc_function code that was common to
5254 {dbx,coff,mips}read.c to symtab.c.
5255 In the process, I think I cleaned things up a bit.
5256 At the same time, moved obsavestring and obconcat to symtab.c.
5259 Removed obsolete condense_addl_misc_bunches (use
5260 condense_misc_bunches(1) instead).
5263 Needed to include <sys/dir>, at least on DECstations.
5265 valops.c, mips-tdep.c, tm-mips.h:
5266 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5267 conventions (when STACK_ALIGN is insufficient).
5268 Needed on mips, where doubles need 8-byte alignment,
5269 but ints only need 4.
5272 Removed cruft that was not being used.
5273 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5276 Print $ before register-names (I think that makes things a little
5278 Never print two instructions, even if one delays.
5279 Removed hex-disassemble set_cmd. (This is not mips-specific,
5280 so I think the argument is whether it is generally worthwhile or not.
5281 I'm inclined to think not, given how easy it is to
5282 convert between radixes in gdb.)
5285 This is basically Alessando's code.
5286 It doesn't use obstacks; I changed it to use obstacks
5287 in a few minor places where using malloc causes a
5288 memory leak. (Probably, more places could/should be changed.)
5289 I added record_misc_function where it was missing.
5290 In symbol_file_command and add_file_command, I tried
5291 to make the code consistent with more recent versions.
5292 Minor sylistic changes in parse_procedure.
5293 Make a .gdbinfo. psuedo-symbol point back to the real
5294 procedure symbol (using the isym field).
5297 This is basically from my port, but with a lot of details
5298 and a number of routines merged in from Alessando's version.
5299 I basically used my code "raw" backtrace (use heuristics
5300 from the actual code, rather than symbol table info) - though
5301 the idea is Alessandro's. I feel my code is a little cleaner
5302 here, particularly in being a little more flexible, such as being
5303 able to handle gcc-produced code (which it now can).
5304 It also doesn't do frame caching (which is not useful
5305 more recent gdb versions).
5306 I also used my code for push_/pop_dummy, more or less.
5307 I tried to incorporate AF's code for testing sigtramp
5308 while backtracing; I probably got it wrong.
5309 Added mips_print_register, which tries to scrunch as much
5310 information as possible on a screen...
5311 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5312 under mips-pinsn.c), I don't see anything mips-specific here,
5313 and I don't see it being all that useful anyway.
5316 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5317 Use more register names (rather than hard-cases numbers).
5319 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5321 * Hack up 3.90.11 changes:
5323 * Makefile.dist (depend): parameterize $(GCC).
5324 Add solib.c and solib.o.
5325 (readline): Fix vpath for both absolute or relative SRCDIR.
5327 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5328 Also, let the part I didn't understand at least compile so
5329 I can test the rest. FIXME.
5331 * dbxread.c: Fix thinko using strcmp.
5332 (init_psymbol_list): declare static.
5333 (partial_symbol_file_open): Comment cleanups better, avoid
5334 cleaning up the string table since the caller will do that.
5335 Move the stat for mod time into symbol_file_command, temporarily.
5336 (There should be a mod time for each symbol file, eventually,
5337 to control its rereading. FIXME.)
5339 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5340 SunOS, which gives error for shared libs otherwise. (From
5341 Schaefer, probably FIXME needs work for portability.)
5343 * solib.c: Move #include "param.h" to work.
5344 Lowercase all the Uppercase Letters In the Messages.
5345 (find_solib): Clean up inferior_so_name for debug printouts.
5346 Allow no argument, to mean all shared libraries.
5348 * symmisc.c: include param.h to get CLEAR_SOLIB.
5350 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)

5394 (condense_misc_bunches): do "misc_function_count = j" regardless
5396 Take code which is shared between symbol_file_command and
5397 add_file_command and put it into partial_symbol_file_{open,read}.
5398 Split add_file_command into add_file_command and add_file.
5399 Make psymtab_to_symtab read in the string table if the file
5401 Two new parameters to read_dbx_symtab and start_psymtab.
5402 tm-sunos.h: New file.
5404 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)

5421 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5423 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5425 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386

5440 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5442 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5444 config.gdb: If srcdir != ., create readline directory and
5445 copy a makefile into it.
5447 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5448 consistency with POSIX.
5450 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5451 when we exit its exp_valid_block.
5453 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5455 * Makefile.dist: Bump version to 3.91.3.
5457 * Clean up handling of breakpoint commands (somewhat).
5458 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5460 inferior.h: Add breakpoint_proceeded to inferior status struct
5461 and globals; save it and restore it.
5462 (clear_breakpoint_commands): Cleanup, remove old #define.
5464 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5465 (save_inferior_status, restore_inferior_status): handle it also.
5466 (proceed): Remove earlier code that set breakpoint_proceeded.
5467 It is now set only in clear_proceed_status.
5468 (clear_proceed_status): Cleanup, use bpstat_clear rather
5469 than clear_breakpoint_commands. No callers need the stop_bpstat
5470 between clear_proceed_status and proceed.
5472 infcmd.c: Add breakpoint_proceeded definition and comment.
5473 (cont_command, jump_command, signal_command): Move call to
5474 clear_proceed_status right next to call to proceed.
5476 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5477 caller's argument while running down the chain of breakpoints.
5478 Use new variable "breakpoint_proceeded" to determine when
5479 a command that it executes moves the inferior past the
5481 (bpstat_clear): Handle NULL argument.
5482 (bpstat_clear_actions): Avoid useless call to
5483 breakpoint_auto_delete.
5484 (delete_breakpoint): Clean up bpstat's that are pointing to
5485 the deleted breakpoint from the stop_bpstat chain.
5486 (breakpoint_auto_delete): Simplify.
5488 * Clean up handling of EOF, error on stdin, etc. This was
5489 prompted by a network problem that caused gdb to go into an
5490 infinite loop filling up its malloc'd memory.
5492 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5493 not clear_breakpoints_commands, which is now gone.
5494 (main): If command_loop returns (e.g. from EOF on stdin), do
5495 a quit_command (looping back to command_loop if quit_command
5496 doesn't really quit).
5497 (command_loop): check result from command_line_input and
5498 exit if it returns NULL, rather than passing the NULL to
5500 (gdb_readline): Free malloc'd result space before returning
5503 * utils.c (query): Handle C-d to mean "yes", just as if the
5504 input was not a terminal. Also avoid infinite loop if EOF
5505 occurs in mid-input-line before newline. This allows
5506 query to be used at EOF on stdin with reasonable results.
5508 * infrun.c (proceed): Set breakpoint_proceeded.
5510 * values.c (value_as_long): Avoid infinite recursion for enums.
5511 (_initialize_values): Fix typo in help msg (kingdon).
5513 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5514 RL_LIB for linking. This allows -lreadline for linking
5515 and nothing for dependencies, once readline is a real library.
5517 * config.gdb: Jim Kingdon: give useful error message if the
5518 host or target type is not recognized.
5520 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5521 it just defines it. Dumb, but deal with it.
5523 * Jim Kingdon suggests:
5524 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5526 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5528 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5530 * Clean up Bothner's changes.
5532 * blockframe.c (clear_pc_function_cache): New function.
5533 * blockframe.c: remake cache_pc_function_* static.
5534 * dbxread.c (symbol_file_command): remove references to
5535 cache_pc_function_* variables.
5536 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5537 * printcmd.c: Avoid kludging a global variable (addressprint)
5538 to avoid printing the address of a string twice. Instead,
5539 pass the format letter 's' down low enough that it can be seen
5540 to avoid this problem.
5541 (print_formatted): Pass format arg to value_print.
5542 (restore_addressprint): Remove function.
5543 (do_examine): Avoid hacking addressprint, cleanups and such.
5544 (print_frame_args): Add a comment to a Bothner change.
5545 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5546 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5547 to wipe out the values cached in blockframe.c.
5548 * symtab.c (find_method): Add comment saying how big you must
5549 allocate to be "big enough". Per being terse again.
5550 * valprint.c (val_print): Handle format letter "s" to print
5551 strings without addresses. Add comment to vtbl printing code
5552 which casts with wild abandon. Rearrange reference-printing
5554 @0xaddr: value (print w/addressprint)
5555 value (print w/~addressprint)
5556 @0xaddr (parameter lists w/addressprint)
5557 or nothing (parameter lists w/o addressprint)
5559 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5561 * Merge more changes from Per Bothner:
5563 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5564 annoying) that I tried to improve it. Here are my suggestions.
5566 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5569 Do automatic de-reference when taking the address of a reference.
5571 Don't deref_ref when printing parameter lists.
5573 More attempts at treating refernences properly.
5575 In val_print, if deref_ref==0, don't print dangling " = ".
5577 Add COERCE_REF macro, which de-references an REF.
5579 * Merge changes from Per Bothner:
5581 * Fixed (Sony news)-specific configuration problems.
5582 * Fixed other problems with using vanilla pcc and libc (enum problems;
5583 assumption that vsprintf exists).
5584 * Some major speed-ups (finc_pc_partial_function now caches a match;
5585 parsing avoids duplicate symbol_lookup calls).
5586 * Changed handling of baseclasses (no longer use baseclasses field
5587 of struct type, use the first n_baseclasses fields instead).
5588 * Various minor changes/fixes, most C++-related.
5591 Cache the most previous match from find_pc_partial_function.
5592 (Save both low and high ends of matching function's pc range.)
5593 This speeds up the loop of infrun.c:wait_for_inferior quite
5594 a bit, and makes step/next commands much zippier.
5596 Added an enum->int cast (otherwise, some compilers barf).
5598 No longer set baseclass offset to 0, since multiple
5599 inheritance now mostly works.
5600 Added a number of casts, to shut up compiler warnings
5601 (after stabs where made enums, not ints).
5602 When discarding a symbol table (in symbol_file_command),
5603 must clear the cache introduced in blockframe.c.
5604 Don't convert $vtbl_ptr_type to vtbl any more.
5605 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5606 Mask off sign bit emitted by g++ for virtual table offset.
5607 Set voffset to -1 (not 1) for static member functions.
5609 Changed parsing/lexing of names to avoid doing symbol lookup twice
5610 (once when lexing to determine symbol class, once for real).
5611 Now only call symbol_lookup once. Fields of 'this' win especially big.
5613 Subpress printing addr twice in the case of 'x/s addr'.
5615 lookup_basetype_type is no longer used.
5616 Add find_methods as recursive helper function to decode_line_1.
5617 This allows multiple inheritance to work.
5618 Also, once one or more matches has been found, do not look in
5619 base-classes. (Baseclass methods would be overridden, anyway.)
5621 Removed baseclasses array in struct type.
5622 Instead of using baseclasses[i], use fields[i-1].
5623 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5624 Changed sign convention of voffset (previous was inconsistent).
5626 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5628 Used to assume existence of vsprintf. Re-written to not need it
5629 if HAVE_VPRINTF is undefined.
5631 typecmp was too pessimistic. Made it less so.
5633 Don't print space after address.
5634 If vtable points to a misc symbol (with 0 offset), print it,
5635 since that indicates the actual class of the object.
5636 Changed ype_print_derivation_info to use new inheritance
5637 scheme (without baseclasses vector).
5639 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5640 Also, changes needed because TYPE_BASECLASSES were removed.
5642 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5644 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5647 If there is no path set, and the symbols don't indicate what directory
5648 a file was compiled in, look in the current directory. But either
5649 a path or a known compilation directory will prevent this.
5652 Three independent bug fixes:
5653 * Remove the #if 0 block that breaks some stuff.
5654 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5655 adapt gdb to either SunOS 4.0.* or 4.1.
5656 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5659 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5662 (type_print) Demangle the name being printed.
5663 (type_print_base) Handle botched demangling without coredump (tiemann).
5666 (check_stub_method): Document routine.
5667 (tiemann) fix bug for no-arg functions
5668 Avoid clobbering beyond end of malloc'd storage.
5669 Terminate the argument list properly.
5671 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5673 * Changes merged by John Gilmore:
5676 In breakpoint_1, use new print_address_symbolic instead
5677 of find_pc_partial_function. (This forces use of assembler-level
5678 addresses, and avoids misleading non-mangled source-level names.)
5680 Generalize ansi argument such that -1 means skip arglist totally.
5681 Removed global variable print_ansi_qualifiers (which made
5682 code non-reentrant), in favor of extra explicit arguments
5683 to internal routines.
5685 Add new helper function print_address_symbolic.
5686 Use find_pc_misc_function instead of find_pc_partial_function
5687 (since we want assembler-level symbols here).
5689 Print unknown function as just "f (...)", not "f (...) (...)".
5690 Use new fputs_demangled explicitly.
5692 Fixed a typing violation (problem: value.h cannot be imported
5693 without renaming many variable in this file).
5694 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5695 decode_line_1: Moved forward some never-reached code.
5696 Made decode_line_2 skip function prologues correctly.
5698 fputs_filtered should not demangle by default.
5699 Add new fputs_demangled to demangle on demand..
5701 Change value_struct_elt to use value_primitive_field (using recursive
5702 utility function search_struct_field). This allows foo.bar to work
5703 for multiple inheritance (so far only for data fields).
5704 Change check_field in the same way (recursive helper function
5705 to support multiple inheritance).
5706 (Note: there are more of these problems that I haven't fixed.
5707 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5708 value_of_this: 'this' symbol name is now just "this", note "$this".
5710 Don't print static members.
5711 Avoid printing "members of <type>" if there are none.
5712 Simplified type_print_derivation_info by merging duplicate code.
5713 Remove useless blank lines in type_print_base (ptype command).
5715 Added declaration of new routine value_primitive_field.
5717 Added value_primitive_field which is generalized version of
5718 value_field that can handle multiple inheritance (non-zero offsets etc).
5719 Re-implemented value_field to call value_primitive_field.
5721 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
5723 * infcmd.c -- insert else to avoid 'delete env' coredump when you
5724 delete the whole environment. Karl Berry reported the bug.
5725 * source.c - fix openp to avoid //'s in filenames, which
5726 trigger an Emacs bug causing it to not be able to find files
5727 when running gdb in a window.
5728 * dbxread.c - zap the #if 0 that botches the add-file code.
5729 It seems to work a lot better without all the code commented out.
5731 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
5733 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
5736 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
5738 * Makefile - added a ${CFLAGS} to a couple of entries,
5739 added remote-sa.sparc.c
5740 * added remote.sa-sparc.c, a modification of remote.c
5741 which conducts a dialog directly with the SparcStation prom.
5742 * breakpoint.c, infrun.c, sparcdep.c added
5743 remote_insert_breakpoint(), and remote_remove_breakpoint()
5744 to breakpoint.c instead of directly writing breakpoint instructions.
5745 * sparcdep.c on remote_debugging,there is no need
5746 to remove signle step breakpoint instructions.
5747 * main.c added "-epoch" flag and "int epoch_interface" to main.c
5749 * printcmd.c - epoch interface sends lisp expressions to open up
5750 epoch windows on inspection.
5751 * valprint.c - added arrayprint, and addressprint and made adding
5752 format controls easier
5753 * wait.h added a couple of undef's because we were getting
5754 complaints about WSTOPSIG and WTERMSIG begin redefined.
5757 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
5759 * symtab.c (decode_line_1): Add support for handling method stubs
5760 in the type information.

5764 * values.c (baseclass_addr): Run loop from INDEX+1 to
5765 N_BASECLASSES; otherwise, we can still get into a loop.
5766 @@ This should be restructured to use a cleaner search strategy.
5768 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
5770 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
5771 abbreviation "Tt" for tags which have the same name as their
5774 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
5776 * symtab.c (list_symbols): add ability to set breakpoints on all
5777 the functions which match a particular regular expression.
5779 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
5781 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
5782 should print ANSI qualifiers (such as `const' and `volatile').
5783 All callers changed to call with ANSI == 1, except from
5784 `check_method_stub', which uses old-style syntax.
5786 * symseg.h (struct fn_field): Remove unneccessary `args' field.
5787 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
5789 * values.c (check_stub_method): New function.
5791 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
5793 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
5794 * valprint (type_print_base): Ditto.
5796 * symtab.c (gdb_mangle_typename): New function.
5798 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
5800 * breakpoint.c (catch_command): New function. Provides a
5801 mechanism to set breakpoints based on catch clauses.
5802 (disable_catch): Similar, but disables breakpoints on catch
5804 (delete_catch): Similar, but deleted breakpoints on catch clauses.
5806 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
5808 * blockframe.c (blockvector_for_pc): New function.
5809 * blockframe.c (block_for_pc): Changed to call
5810 `blockvector_for_pc' and get the block itself.
5812 * stack.c (catch_info): New function. Prints info about
5813 exceptions which can be caught in the current frame.
5814 * stack.c (print_frame_label_vars): New function. Similar to
5815 `print_frame_local_vars'.
5816 * stack.c (print_block_frame_labels): Prints out labels that are
5817 defined in this frame. These labels are exceptions that can be
5820 * dbxread.c: Updated to handle N_CATCH symtab types.
5822 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
5824 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
5825 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
5826 when printing the type.
5828 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
5830 * valprint.c (val_print): Use `baseclass_addr' to access the
5831 baseclasses pointed to via the derived class object at VALADDR.
5833 * values.c (baseclass_addr): New function. Casts derived pointers
5834 to baseclass pointers taking virtual baseclasses and multiple
5835 inheritance into account.
5837 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5841 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5843 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
5844 exp_valid_block field correctly.
5846 * infrun.c (wait_for_inferior): When checking "don't even think
5847 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
5848 also check step_resume_breakpoint.
5849 Insert breakpoints and continue (not step) if
5850 step_resume_break_address != NULL, even if another_trap.
5851 If trap_expected and we enter sigtramp, then set up a
5853 If trap_expected is set when we hit the step_resume_break,
5855 When calling resume and trap_expected says tell resume to step
5856 (2 places), also check step_resume_break_address.
5858 * infrun.c (wait_for_inferior): Don't set
5859 prev_{pc,sp,func_{start,name}} before calling wait ().
5860 Do set them after exiting loop.

5862 (start_inferior): Initialize them.
5864 Thu May 3 00:15:11 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5866 * infrun.c (wait_for_inferior, after check for trap_expected > 1):
5867 Restore old code which distinguishes between trap_expected and
5868 running_in_shell, just make the latter take any non-TRAP signal,
5871 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
5873 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.
5874 xconfig/3b1 (CC,PINSN_CC): Define.

5895 * valprint.c (value_print): Check VALUE_OPTIMIZED_OUT flag.
5897 * value.h: Add optimized_out field and change lazy field to
5898 char. Add macro VALUE_OPTIMIZED_OUT.
5900 * i386-pinsn.c: Change from Eirik Fuller to write to stream directly
5901 instead of stuffing things in buffers (oappend, etc).
5903 * breakpoint.c (bpstat_do_actions): If *BSP is set to NULL by
5904 execute_command, exit both loops.
5906 * Makefile.dist: Don't set TARGET_ARCH. Add .c.o rule.

5911 rgdb.c, rserial.c, rudp.c, serial.c, udp.c, xdep.h,
5913 m68k-xdep.c, coredep.c: Wrap in #if !defined (RDB).
5915 * valops.c (value_struct_elt), values.c (value_static_field):
5916 Change error messages to remove references to `info methods'.

5921 infrun.c (start_inferior): Add START_INFERIOR_HOOK.
5922 infcmd.c [SHIFT_INST_REGS]: New code.

5930 Mon Apr 23 10:42:21 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5933 findvar.c (get_saved_register): New function.
5934 findvar.c: Rewrite code which called find_saved_register to
5935 call get_saved_register instead.
5937 Sun Apr 22 14:47:51 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5939 * valprint.c (val_print): Change error message printed when
5940 the type has TYPE_FLAG_STUB set.

5953 (store_inferior_registers): Don't call read_register_bytes.
5954 symmetry-xdep.c (store_inferior_registers):
5955 #if 0 out code to fetch registers.
5957 * values.c (value_as_long): Call COERCE_ARRAY.
5959 * tm-sun3.h: Include tm-68k.h not m-68k.h
