1 Sat Oct 26 00:16:32 1991 John Gilmore (gnu at cygus.com)
3 * buildsym.c: New file. Breaks out symbol-table-building routines
4 from dbxread.c, so they can be shared with xcoffread.c.
5 * buildsym.h: New file. Declarations for buildsym.c users.
6 * dbxread.c: Remove large chunks into buildsym.c.
7 * Makefile.in: Add buildsym.c and buildsym.h.
9 * symfile.c (syms_from_bfd): New routine.
10 (add_symbol_file): Call it to do the real work.
11 (syms_from_bfd): Initialize entry_point before calling symfile_init.
12 * symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
13 Avoid declaring or setting entry_point (symfile.h & symfile.c cope).
15 Fri Oct 25 18:59:32 1991 Per Bothner (bothner at cygnus.com)
17 Various fixes to improve g++ debugging.
18 * symtab.h: Add is_const and is_volatile flags for each method.
19 These are bit fields - take their space from voffset,
20 which shrinks to 30 bits. Since voffset is now a bitfield,
21 make it unsigned for portability. This changes its interpretation
22 slightly: Static methods now have voffset 1 instead of -1,
23 and virtual offsets start at 2, not 1.
24 * symtab.c: Renamed gdb_mangle_typename to gdb_mangle_name,
25 since it now returns an entire magled method name, not just
26 the type part. This avoids some duplication.
27 It also allows us to correctly mangle const and volatile
28 methods (using the new is_const and is_volatile bit fields
30 * valprint.c (type_print_base), values.c (check_stub_method):
31 Simplify by using new gdb_mangle_name.
32 * values.c (value_headof): Fix to correctly handle single
33 inheritance (actually two fixes, either of which suffices).
34 * dbxread.c (read_struct_type): Handle const and volatile
36 * dbxread.c (read_struct_type): Yet one more place where
37 we must handle '\\' continuations.
38 * valprint.c (vtbl_ptr_name): Add final '\0'.
40 Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com)
42 * tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of
43 short return values for sparc and 68k. Patch from Paul Eggert.
45 * coffread.c, coredep.c, i386-xdep.c: install patches for
46 SysV/386 3.2 from Mauro DePalma.
48 Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
50 * core.c (core_file_info), exec.c (exec_file_info): Print file
51 type. Use printf_filtered.
53 * valops.c (value_fetch_lazy): Avoid 0-length fetches.
55 Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
57 * dwarfread.c: Add casts to remove compiler warnings.
59 * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
60 tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
61 tm-sun3.h: Remove locally duplicated code for calling functions
62 in the inferior. The only differences were in the specific trap
63 vectors used and whether or not an fpu was present. These are
64 now handled by appropriate definitions of BPT_VECTOR and
65 HAVE_68881 respectively. Other minor obvious cleanups.
67 * valops.c: Correct a minor misspelling.
69 * utils.c: Remove local BSD/USG hacks that are now in libiberty.
71 * dwarfread.c: Remove prototype for dwarfwarn. Does not work
74 Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
76 * stack.c (frame_command): Always print. Use new
77 frame_select_command to select a frame without printing.
79 * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
81 Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
83 * dwarfread.c: New file for DWARF debugging format support.
85 * elfread.c: New file for ELF object file format support.
87 * procfs.c: New file for SVR4 /proc (process file system) support.
89 * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
92 * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
94 * xm-m68k.h: New file for host machines with m68k cpu.
96 * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
97 Add elfread.o and dwarfread.o to OBS.
99 * symfile.h: Add "elf" to list of supported formats in comment.
101 * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
102 types to gdb, builtin_type_long_double, builtin_type_complex, and
103 builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
104 TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
105 TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
106 TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
107 types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
109 * infrun.c: When using SVR4 /proc interface instead of ptrace(),
110 call proc_set_exec_trap() to setup child to stop at first instruction.
112 * inftarg.c: When using SVR4 /proc interface, call proc_wait()
115 * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
116 supply_fpregset(), and fill_fpregset(), which are machine
117 dependent support routines for SVR4 /proc interface.
119 * utils.c: Add warning_setup() and warning(). Warning() behaves
120 the same as error() except that it returns normally rather than
121 jumping back to command level. Modules that don't want to call
122 warning() for some reason, but want to produce their own warnings,
123 can call warning_setup() to ensure compatibility with the way
124 warning() and error() deal with the terminal.
126 * symtab.c: Make internal errors produce more useful messages.
128 * tm-68k.h: Move code that is duplicated in almost every single
129 m68k based machine's configuration files to this common file.
130 Duplications in the configuration files still need to be removed
133 * infrun.c (child_create_inferior): System V versions must call
134 setpgrp() with no arguments, to comply with prototyping typically
137 * munch: Add support for SVR4 style nm output.
139 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
140 file specific fields from the partial symbol table structure and
141 replace them with a pointer to private data for each different
142 flavor of object file reader to initialize appropriately.
144 Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
146 * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
149 * mipsread.c (fixup_undef_type): New function. If a struct /
150 union / enum is defined in a header file but nowhere else used,
151 (by typedefing, pointer referencing or declaration) the mipsread code
152 builds the complete tree for the structure but leaves its code as
153 TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
154 Guess its type based on the details of the members.
156 Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
158 * infrun.c (wait_for_inferior): Check return value from
161 Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
163 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
164 by my last edit to this routine.
166 Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
168 * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
169 FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
170 the values before putting them into the dummy code. (From Peter
173 Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
175 * configure.in: added ebmon target.
177 Wed Oct 16 22:49:58 1991 John Gilmore (gnu at cygnus.com)
181 * Makefile.in: Roll VERSION to 4.2.
182 * README, TODO, WHATS.NEW: Update.
184 * core.c (core_open): Improve error message for bad file.
185 Pass .reg virtual memory address to fetch_core_registers to help
186 it find the registers in the core-file header.
187 * coredep.c (fetch_core_registers): Take new argument, use it,
188 and pass it to register_addr to locate the block of registers.
189 * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
191 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
192 Sequent N_FN_SEQ like everybody else's N_FN.
194 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
195 * tm-i386v.h: #endif guck.
196 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
197 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
198 * xconfig/tahoe: Add REGEX, which seems to be missing.
200 * coredep.c: Add <sys/types.h> for SCOnix.
201 * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file.
202 * printcmd.c (print_formatted): Flush output before disassembly.
204 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
206 * doc/refcard.tex (sec "Working Files"): consistent metavars and
207 other improvements, due to comments by François Pinard
208 (pinard@iro.umontreal.ca)
210 * doc/gdb.texinfo (appendix "Installing GDB"): changes in
211 configure, and improvenets related to Pinard's refcard comments
213 Tue Oct 15 08:45:12 1991 John Gilmore (gnu at cygnus.com)
215 Changes from Fred Fish:
216 * tm-68k.h (FPI_REGNUM): Add.
217 * infrun.c (child_create_inferior): flush stdout and stderr
219 * configure.in: Handle amigados, amix hosts and targets.
220 * inflow.c: Handle TIOCGLTC_BROKEN for Amiga.
223 * values.c (show_convenience): Use printf_filtered.
224 * main.c (define_command): Check result of lookup_command for
226 (echo_command): Use printf_filtered, and force output out.
228 * dbxread.c (read_enum_type): Avoid Modula-2 kludge that breaks C
230 * i387-tdep.c (double_to_i387): Fix typo for double_to_ieee_extended.
231 * utils.c (_initialize_utils): If !ISATTY, don't paginate.
232 * configure.in, tconfig/decstation, xconfig/decstation: Rename
233 dec3100 to decstation.
235 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)
237 * doc/gdb.texinfo: Catch up to changes recorded here in ChangeLog
238 (nodes Continuing and Stepping; Memory; Targets) clarifications
241 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
243 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move
244 REGISTER_U_ADDR to corresponding xm- file. Sugg. by Peter Schauer.
246 * symmisc.c (print_partial_symtabs): Add printpsyms debug cmd.
248 * m68k-tdep.c (m68k_push_dummy_frame, m68k_pop_frame): Add
249 generic routines for calling inferior functions.
251 * blockframe.c (inside_main_scope, inside_entry_scope): New.
253 * copying.awk: Filter formfeeds out of copying & warrantee.
254 Make them available as `show copying' and `show warrantee' also.
255 * main.c (print_gnu_advertisement): Advt `show' commands.
257 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)
259 * mach386-xdep.c: Even when cross-compiling, leave in the
260 core-file reading code.
261 * core.c (get_core_registers): Avoid coredump if no .reg section.
263 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
265 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
266 This avoids coredumps under `set print object on' in value_headof
267 (called erroneously by value_from_vtable_info) for `p &struct'
268 or `p *struct'. From Peter Schauer.
270 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
272 * Makefile.in: Roll version to 4.1.2.
273 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
274 size from BFD (but, FIXME, we don't yet read external nlists's and
275 convert them to internal nlists's before handling them -- we still
276 assume they have the same size and alignment.) Use SET_NAMESTRING
278 * exec.c (exec_file_command): Move dead coff-encapsulation code
280 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.
282 Fri Oct 4 22:30:06 1991 John Gilmore (gnu at cygnus.com)
284 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
285 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
287 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
289 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
290 * mips-xdep.c (store_inferior_registers): Don't try to
291 write the (pseudo) FP.
292 * mipsread.c (parse_partial_symbols): Improved algorithm for
293 setting pst->texthigh.
295 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
297 * doc/Makefile: make TEXINPUTS include . everywhere
299 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
301 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
302 vestiges of typevectors, which were for symsegs and are no longer
303 used. (From a question by Eliot Dresselhaus
304 <dresselh@RFT30.nas.nasa.gov>).
306 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
308 * dbxread.c, coffread.c: static-ize functions that were
309 gratuitiously external. (From Fred Fish.)
311 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
313 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
314 until it is large enough.
316 * dbxread.c (read_type): Handle error case slightly better.
317 Make complaint message not C++-specific.
319 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
321 * infrun.c (wait_for_inferior): Fix step/next so that you only
322 stop at the beginning of a new line. This fixes various problems
323 with for loops, nested if-else's and switch statements.
325 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
327 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
328 between symtabs and psymtabs become ordinary error()s.
330 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
331 properly, making "end pc" correct in shared lib psymtabs.
332 (From Guy Harris <guy@auspex.com>.)
334 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
336 * dbxread.c: Enable, but soften, const_vol_complaint.
337 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
338 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
339 should be file-scope, not global.
340 (read_struct_type): Remove ancient multiple-inheritance warning.
341 (read_range_type): Check base type, complain & patch if undefined.
342 * stack.c (frame_info): Demangle the function name in `info stack'.
345 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
347 * eval.c (evaluate_subexp_for_address): Don't use
348 TYPE_POINTER_TYPE directly (it might be zero if this type has
349 never had a pointer created before); use lookup_pointer_type.
350 * symtab.c (lookup_method_type): Arguments were swapped in all
351 callers, so fix it here. I'm amazed this worked at all!
353 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
355 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
356 "bss" rather than "data" symbols, but which still conflict.
359 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
360 * core.c (core_files_info): Shorten output.
361 * exec.c (exec_files_info): Ditto.
362 (build_section_table): Ignore zero-length sections.
363 * language.c, printcmd.c: Lint.
364 * language.h (get_frame_language): Declare.
365 * saber.suppress: update.
366 * stack.c (find_relative_frame): Remove complex code that was
367 #if 0'd, stick with simple code. Lint.
368 * saber.suppress: Update a bit.
369 * symfile.c (add_symbol_file_command): Add "?" to question.
370 * utils.c (parse_escape): Avoid \a due to bdead compilers.
371 * value.h: Declare typedef_print.
373 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
376 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
377 (Reported by Mark Peek <mark@imagen.com>.)
379 * solib.c (solib_map_sections): Relocate all sections, even
380 though only the text section's size is tracked. Mark ld_text
381 for eventual elimination as we generalize to N sections.
383 * infrun.c (wait_for_inferior): Don't check if the PC is in a
384 call_dummy if we were stopped by a random signal that is being
385 passed to the program. This produced wierd results when calling
386 functions in the inferior and signals (e.g. SIGALRM) were in use.
388 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
390 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
391 Bugfix from Paul Eggert <eggert@twinsun.com>.
392 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
393 * valprint.c (print_floating): Print 9 digits for IEEE floats.
396 Mon Sep 23 15:50:07 1991 John Gilmore (gnu at cygnus.com)
398 * Makefile.in: Roll VERSION to 4.1.1.
399 * source.c (line_info): Peter Schauer fixes a bug I introduced in
402 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
406 * Makefile.in (VERSION): Set to 4.1.
407 * language.c (set_language_command): Print useful help message,
408 and restore the language string after giving help.
409 * valprint.c (typedef_print): Print typedef in C or M2.
410 * symtab.c (list_symbols): Use it.
411 * main.c (main): Avoid any output before (gdb) prompt when -q.
412 * language.c (set_language_command): Handle errors by restoring
413 the language string to its current state (fix from A. Beers).
414 * doc/gdbint.texinfo: Roll in information from README. Rearrange
415 "how to install" and "how to print the doc" stuff so it drops
417 * configure.in: Rename rtpc CPU to romp to match config.sub.
418 * README, WHATS.NEW, TODO: Update for gdb-4.1.
420 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
422 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
423 autoloading shared libs, copyright etc on GDB startup, clean up $_
424 and $__ index refs, set/show listsize and related updates to list
425 cmd. New host/target configs.
427 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
429 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
430 from main Makefile.in version definition
431 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
433 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
435 * doc/gdb.texinfo: merge new language-switching and lang-specific
438 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
440 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
441 compilers (which may lack stddef.h).
443 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
445 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
446 N_WARNING are the same except for the N_EXT bit, so just use their
447 values alone, rather than OR-ing them with N_EXT.
449 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
451 * mipsread.c (parse_lines): Deal with negative extended line
454 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
455 global symbol conflicts.
457 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
459 * .gdbinit: Move 'set complaints' to top, so it runs even in
460 case we aren't debugging GDB.
461 * language.c (_initialize_language): Fix type check and range
462 check documentation strings.
463 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
464 language.c can use it. (Though language.c should really not be
465 handling warnings/errors the way it does, FIXME.)
466 * symtab.c (lookup_primitive_type): const lint.
468 Bugfix from Peter Schauer:
469 * source.c (lines_to_list): Make signed, to avoid comparison
470 going unsigned and complaining that -3 is too high for 21 lines.
471 * stack.c (lines_to_list): Ditto.
473 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
475 * Makefile.in (HFILES): Add minimon.h.
476 (VERSION): Roll version number to 4.0.95.
477 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
478 New rules for building distributions. Normal distribution
479 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
480 one level up from here; it calls make-proto-gdb.dir to build a
481 directory `proto-gdb' which is an image of the release. The old
482 `gdb.tar.Z' rule still works too.
483 * config.sub, configure: Roll in latest from ..
485 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
487 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
488 new-target, and new-config chapters; fix minor typos; come closer
489 to usual GNU markup conventions for @file @samp @code @var.
491 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
493 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
494 * mipsread.c (parse_partial_symbols): Enter the name of all
495 structs/unions... into the psymtab so we can access them if the
496 symtab is not read in.
497 * mips-tdep.c: Remove some unneeded #includes.
498 * xconfig/dec3100: Add HAVE_STRSTR.
500 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
502 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
503 * c-exp.y, m2-exp.y: Lint.
504 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.

609 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
611 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
612 entries are enclosed herein. Not all of these changes
613 have been merged into the master GDB sources -- check the
614 ChangeLog above here for the merge log.
616 Mon Jun 3 17:05:45 EDT 1991
618 m2-exp.y Created. Tested outside of GDB for a few days. Proper
619 operators were added, C specific operators and tokens
620 removed. yylex() revamped to some extent. Still things
621 missing from the grammar, such as sets.
622 Tested for two weeks in GDB v3.5.
624 Tue Jun 11 17:23:48 EDT 1991
626 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
627 so they are built-in. Sort of a hack.
629 Fri Jun 14 12:53:51 EDT 1991
631 m2-exp.y Added range checking for numeric constants. Any numeric
632 constant is assumed to be of builtin type INTEGER unless:
633 (1) it is octal or hexadecimal, in which case it is a
634 CARDINAL; (2) it is too big to fit into an INTEGER, in
635 which case it is a CARDINAL.
636 eval.c Added simple range checking for +, -, and * on integers.
637 Doesn't work very well for *, since 6 * 1,000,000,000 =
638 1,705,032,704, which fails the simple test of result >=
639 first_operand, no matter in what order the operands are.
641 Tue Jun 18 14:11:30 EDT 1991
643 Broke the parser into parts, one containing the C grammar and the other
644 containing code to be shared by all of the grammars.
646 The following files no longer exist:
651 The following files were added:
653 c-exp.y (The C grammar)
654 m2-exp.y (The Modula-2 grammar)
655 parser-code.c (Code that is shared by the above grammar)
659 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
660 now necessary to use the Bison compiler compiler, since it
661 will generate function/variable prefixes other than yy.
663 Tue Jun 18 16:47:49 EDT 1991
665 symtab.[ch] Added the external variable working_lang, than holds the
666 value of the current working language.
667 Added the ennumerated type language_mode, with the values
668 language_auto and language_manual, the former meaning that
669 GDB sets working_lang as needed, and the latter meaning
670 that the value of working_lang is totally under user
672 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
673 REAL, BOOLEAN and CHAR. Also added the type codes
674 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
675 utils.c Added set_language_command and show_language_command to
676 implement the GDB support commands "set language" and
678 expression.h A number of identifiers were added to the type exp_opcode
679 to facilitate Modula-2 builtin functions, integer
680 division, and array indexing.
682 Wed Jun 19 13:25:58 EDT 1991
684 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
685 if the language specified by working_lang requires the use
686 of strict typing of expressions. Eventually, even this
687 will be able to be changed by the user.
688 Added the macro RANGE_CHECK, which evaluates to non-zero
689 if the language specified by working_lang requires the
690 checking of a value against the domain of its type.
691 Eventually, even this will be able to be changed by the
693 language.[ch] Predicates involving types (simple_type, ordered_type,
694 same_type, integral_type, numeric_type, character_type,
695 boolean_type, float_type) are added. These predicates are
696 based on the current value of working_lang, and are handy
699 Wed Jun 19 15:39:34 EDT 1991
701 eval.c Added the function type_array_rank which computes the rank
703 valarith.c Added the funtion value_bool, which when given a integer
704 value.h value (ie. struct value *) as an argument, it returns a
705 boolean value (ie. struct value *) true if that integer
706 is non-zero, and a boolean value false otherwise.
707 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
708 will print out properly.
710 Wed Jun 19 16:36:34 EDT 1991
712 valops.c Added the function value_capitalize, which returns it
713 value.h argument capitalized if its argument is a lowercase
714 letter, or the argument unchanged if its argument is not a
716 valarith.c Added the function range_check_p, which returns non-zero
717 value.h if its value argument is between the integral bounds upper
719 Added the function range_check_enum_p, which makes sure
720 that its value argument is a valid member of the domain of
722 Added the function range_check_range_p, which makes sure
723 its value argument lies between the upper and lower bounds
724 of its type argument, which must be a ranged type.
725 Added the function check_array_index, which range and type
726 checks an index of an array.
727 Added the function value_multi_subscript, which computes
728 array[idx1,idx2...idxN], given a value array and an array
729 of values representing indicies.
730 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
731 unpack_long to work with TYPE_CODE_BOOL and
734 Wed Jun 19 18:04:08 EDT 1991
736 symtab.c Stored pervasive types in a structure and make
737 lookup_pervasive_type() a lookup function that was based
738 on working_lang. If lookup_pervasive_type() returned
739 non-zero, then that value was returned (a fix, since
740 before it simply wouldn't return the pervasive type.)
741 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
742 non-zero if the language specified by working_lang means
743 "conversion" when it says "cast".
744 valops.c Added the function value_real_cast(), which performs a
745 value.h *cast*, not a *conversion*, which is what value_cast()
746 does when it can. In particular,
747 value_cast(<float_type>,4) = 4.0, while
748 value_real_cast(<float_type>,4) = some mess.
749 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
750 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
751 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
752 and MIN on integral types. *NOTE*: These are currently
753 hardcoded to work only if there are 8 bits per storage
755 eval.c Made logical functions call value_bool to return a
756 properly typed boolean value, based on working_lang.
758 Thu Jun 20 11:55:27 EDT 1991
760 valprint.c Types now print out in a Modula-2 fashion. This works for
761 the cases when the type is printed out step-by-step, that
762 is, it doesn't work when the name of a structured type
763 (which includes the keyword "struct", etc.) is simply
765 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
766 since type specifications in C and Modula-2 are very
767 different. The C printing of a type is very recursive,
768 whereas in Modula-2 it is generally very simple. C has
769 type prefixes and suffixes, which have no real analogue in
770 Modula-2. Maybe type_print() should call a language
771 specific type printer. This is also advantageous if we
772 compile GDB to exclude some of the languages. We'll just
773 leave those functions out.
775 Thu Jun 20 16:57:10 EDT 1991
777 dbxread.c When reading the complete symbol table in (via
778 psymtab_to_symtab()), the number and types of function
779 arguments are added to a function type. define_symbol()
780 calls add_param_to_type() to accomplish this.
781 Assumption: when we come across a function definition
782 (N_FUN symbol with an 'f' or 'F' in the name), its
783 arguments will appear before another function definition.
784 When a function is found, a pointer to its type is placed
785 in the global in_function_type. Changes that
786 add_param_to_type() makes are to this global.
787 valprint.c The type of a function now includes (for Modula-2) the
788 types of its parameters.
789 eval.c Type checking and a check for the proper number of
790 arguments is now done for function calls. Not sure of the
791 impact this has on C++ member function yet.
793 Thu Jun 20 19:58:48 EDT 1991
795 valprint.c Rewrote the type printer. Broke it into two language
796 specific parts, adding the functions type_print_m2() and
798 An unfortunate consequence is this: if you debugging a C
799 program in Modula-2 mode (why?), info types does not work
800 well with regular expressions, since the types are printed
801 out in Modula-2 terminology, but stored in C terminology.
802 language.[ch] Added the functions new_type_last(), type_keyword(), and
803 type_sep() to aid in the printing of typedefs.
804 symtab.c Made the printing of typedefs as language independent as
805 possible through calls to new_type_last(), type_keyword(),
808 Fri Jun 21 11:50:26 EDT 1991
810 dbxread.c Check all incoming ennumerated types. If it looks like
811 Modula-2's BOOLEAN type, then change the type_code of the
812 type to TYPE_CODE_BOOL so we can process it as a boolean
814 valprint.c Replaced some of the 0x%x with calls to sprintf and
815 hexformat() in val_print().
816 language.[ch] Added the function hex_to_string(), which converts its
817 integral argument to a hexadecimal number (format is
818 language based) and returns the result as a string.
820 Mon Jun 24 12:25:07 EDT 1991
822 valprint.c Some functions call type_print_1() directly, instead of
823 value.h using type_print(), so they can specify where (column) to
824 print things. Since type_print() takes care of language
825 dependence, that needs to be called first. Added a
826 parameter depth to type_print() (so it is now like
827 type_print_1). Changed type_print to type_print_at, and
828 made type_print a macro that passes a depth argument of
830 symmisc.c Changed all calls to type_print_1 to calls to
832 Makefile.dist Made it possible to build GDB for a specific set of
833 depend languages. Do this by passing a definition for the macro
834 LANGS to make. LANGS should be a string containing a
835 space-separated list of language names (ie. LANGS="c m2").
836 The default is to build all languages. Note that grammar
837 files must follow the naming convention of <lang>-exp.y.
838 gdb.lang This holds the current value of the LANGS macro. It is
839 examined every time make is called, and is updated if
841 eval.c Added #ifdef _LANG_<lang> to these files.
842 expread.c Still need to add them to dbxread.c and coffread.c.
850 Mon Jun 24 16:33:11 EDT 1991
852 language.[ch] Added the functions hexformat_pre() and
853 hex_to_string_pre(), which take a prefix argument to
854 include in the format string. Thus, hexformat_pre("08") will
855 return "0x08x" (if the working language is language_c).
856 Made hexformat() and hex_to_string() calls to the above
857 with "" as the prefix argument.
859 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
860 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
861 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
862 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
863 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
864 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
865 valprint.c, vax-pinsn.c
867 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
868 calls to hexformat() and hex_to_string(). Format strings without
869 the leading "0x" were ignored.
871 depend Updated to take the above into account.
874 Tue Jun 25 15:27:18 EDT 1991
876 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
877 and type_check_t to keep track of the current state of
878 range and type checking.
879 main.c Added the variables range_mode, range_check, type_mode,
880 and type_check to record the current state of range and
881 type checking. Added initialization code to main().
882 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
886 Tue Jun 25 17:57:08 EDT 1991
888 dbxread.c process_one_symbol() updates the variable (enum language)
889 source_lang based on the extension of the filename
890 contained in the N_SO sybmol that started this symtab.
891 When end_symtab() is called, the value of source_lang is
892 put into the language field.
893 stack.c select_frame() sets working_lang (and possibly type_check
894 and range_check) to the language field of the symtab
895 associated with the frame that is selected if working_mode
896 is language_auto. If working_mode is language_manual, a
897 warning is printed and working_lang is not set.
898 language.c Added the function set_type_range(), which sets the value of
899 type_check and range_check (if their modes call for
900 automatic setting) based on the current value of
901 working_lang. A non-zero argument will cause the current
902 settings to be output.
905 Wed Jun 26 14:51:40 EDT 1991
907 eval.c Added range checks on assignment.
908 m2-exp.y Added the grammar for sets to the language. Currently,
909 these do not do anything except print an error message.
911 Wed Jun 26 17:01:04 EDT 1991
913 m2-exp.y Added the ability for parse_number() to parse negative
914 numbers. A global flag is set upon encountering a unary
915 minus. This was done to make, for example, 1 parse as a
916 CARDINAL, and not as an integer, per Wirth's examples in
917 Programming in Modula-2 ed.4.
918 valprint.c Added support for "set radix 2" by then setting
919 output_format to 't'.
920 eval.c Implemented range checking on subrange types. Added calls
921 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
922 Implemented MIN and MAX for ennumerated types. The
923 minimum value of an ennumerated type is defined by Wirth
924 as the first identifier, and the maximum as the last.
925 m2-exp.y Made octal numbers ending with "B" be characters and those
926 ending with "C" be numbers, per Wirth's book. (p. 34)
928 Thu Jun 27 14:11:52 EDT 1991
930 stack.c select_frame() now only sets working_lang, it does not
931 notify the user. If working_mode is language_manual, then
932 a warning is issued once.
933 main.c At the end of each call to execute_command(), working_lang
934 is checked against the local static (enum language)
935 current. If they differ and working_mode is
936 language_auto, the new settings of language, type and
937 range checking are printed out.
938 stack.c Modified frame_info() to include the language of the
939 current frame in the output of "info frame".
940 language.[ch] Added the function language_str() which returns the name
941 of the current language.
943 Fri Jun 28 15:33:14 EDT 1991
945 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
946 the language. INCL and DECL currently cause an error,
947 since sets are not implemented yet. INC and DEC are
948 implemented as PREINCREMENT/PREDECREMENT with one
949 argument, and as ASSIGN_MODIFY with two arguments.
950 eval.c Added type checking to the above cases.
951 value.h Added not_lval_constant to the lval_type ennumerated type.
952 not_lval_constant means that the value is a constant
953 value; that is 3 or 'a' or TRUE, not as in a constant
954 identifier. This is used to help coerce numbers such as 3
955 to either signed or unsigned numbers.
956 valops.c Added the function value_coerce_constants() which coerces
957 constant integers as following: if one is a constant and
958 the other is not, the constant's type is set to the type
959 of the other argument. If both are constants and one is
960 signed, the other is converted to a signed constant.
962 Sat Jun 29 17:26:29 EDT 1991
964 valarith.c Added a better range checker. It now checks range
965 (successfully) on integral operations [+-] (signed and
966 unsigned) for any C sized type. Still does not work well
968 int_in_size() returns an integer that is coerced to fit into
969 specified number of bytes.
971 Mon Jul 1 13:04:14 EDT 1991
973 language.[ch] Added the function binop_result_type(), which returns the
974 builtin (struct type *) type that would be the result of a
975 binop on the two values V1 and V2.
977 Wed Jul 3 19:22:53 EDT 1991
979 source.c Extended source_info() to include the source language in
980 the output from "info source".
982 Fri Jul 5 13:48:52 EDT 1991
984 utils.c Moved the support functions for the GDB set/show commands
985 dealing with language into language.c.
986 language.c Added the function language_info(), which displays info
987 about the current working language, type and range check
988 settings. Called via the GDB command "info language".
989 Added an initialization routine _initialize_language(),
990 that sets defaults for the language, type and range
991 variables and sets up the new GDB commands.
992 main.c Language setup moved to language.c.
995 Mon Jul 8 10:10:22 EDT 1991
997 valarith.c Debugged the range checker for arithmetic. Still does not
998 work for multiplication very well.
1000 Mon Jul 8 12:40:37 EDT 1991
1002 language.[ch] Added the function value_true() which returns non-zero if
1003 its argument represents a boolean true value.
1004 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1005 check the truth of an expression.
1007 Thu Jul 11 12:51:34 EDT 1991
1009 language.[ch] Added the predicate structured_type(), which returns
1010 non-zero if the argument is a structured type.
1011 Added the predicate pointer_type(), which returns non-zero
1012 if the argument is a pointer type.
1013 eval.c Added the ability to do addition and substraction on
1014 pointers and integers. This case simply bypasses the
1017 Thu Jul 11 14:41:42 EDT 1991
1020 Added the symbol N_DEFD (0x4a) which is a definition
1021 module dependency that is used by the GNU Modula-2
1022 compiler and the linker. It is not important to GDB,
1023 except that [dbx|coff|mips]read.c should ignore these
1026 Fri Jul 12 16:07:00 EDT 1991
1028 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1029 0 in val_print(). Also added statements to the else part
1030 to coerce type (argument to val_print) to a pointer type
1031 if it is an "array of unspecified length".
1032 valops.c Added the function value_m2_string(), which returns a
1033 (value) value which is a constant string, whose type is
1034 (ARRAY [0..n] OF CHAR). The length field of the type
1035 structure is set to zero, so it will be interpreted as an
1036 "array of unspecified length".
1037 stack.c Moved the language/frame mismatch check to
1038 main.c:execute_command().
1039 main.c The working language is recorded each time
1040 execute_command() is executed. If working lang has
1041 changed during its execution, then the new
1042 language/type/range info is printed out for the user. If
1043 the working language does not match the language of the
1044 frame, a warning is issued.
1046 Sat Jul 13 16:16:39 EDT 1991
1048 eval.c Moved all the type-checking stuff for operators to
1049 language.[ch] language.c. This is so we can keep language-specific
1050 stuff (like for what type operators are defined) in
1052 language.[ch] Added the function binop_type_check(), which checks to see
1053 if its two (value) arguments are type-compatible with its
1054 opcode argument. The opcode should represent an operation
1055 involving an operator. Also added the macro function
1056 unop_type_check, which calls binop_type_check with a
1057 NULL second argument.
1058 expprint.c Added Modula-2 operators to the op_print_tab, so info
1059 expression.h break works correctly. Also added "op_string", which
1060 returns the string corresponding to the (enum exp_opcode)
1061 opcode that is its argument.
1064 Sat Jul 13 18:26:18 EDT 1991
1066 coffread.c Added code to record the type of function arguments with
1067 each paricular function. Code is very similar to that
1069 dbxread.c Moved add_param_to_type() to symtab.c
1070 symtab.[ch] Added function add_param_to_type() from dbxread.c
1072 *** NOTE: The above additions have not been tested.
1074 Mon Jul 15 12:50:47 EDT 1991
1076 langauge.[ch] Added the functions type_error and range_error, which work
1077 like error() except if the type/range mode is set to
1078 *_mode_warn, then they do not do a return_to_top_level(),
1079 but merely print a warning.
1080 Also changed [set|show]_[type|range]_command() to support
1081 the new "warn" feature.
1083 Thu Jul 18 17:50:54 EDT 1991
1085 mipsread.c Added code to record the type of function arguments with
1086 each particular function. Code is very similar to that
1089 *** NOTE: The above additions have not been tested.
1091 Fri Jul 19 11:19:10 EDT 1991
1093 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1094 UMIN_OF_SIZE, which when given a size of a numeric type,
1095 return the maximum and minimum value it can hold. UMAX...
1096 and UMIN... return the result for unsigned types.
1097 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1098 struct types. They call above macros.
1099 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1100 avoid a name conlict with the above.
1101 c-exp.y Added range checking on numeric constants in
1102 parse_number() for completeness.
1103 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1104 return 0 if working_lang is not language_c.
1106 Thu Aug 8 14:17:22 EDT 1991
1110 breakpoint.c Documentation strings of some commands changed to
1111 eliminate the references to the C language where
1114 Tue Aug 13 15:48:03 EDT 1991
1116 m2-exp.y Added qualified identifiers to the grammar. The semantics
1117 are slightly different from those of the GDB operator ::
1119 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1120 type_exp, where type_exp is any valid type expression.
1122 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1123 printcmd.c Modified ptype_command() so it actually parses the input
1124 (necessary for type expressions with scope qualifiers).
1125 Added the function ptype_eval() which expects an
1126 expression composed of one OP_TYPE element.
1127 *.[ch] Replaced all occurences of parse_c_expression with
1129 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1131 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1133 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1135 Small fixes from Peter Schauer:
1137 * infrun.c (child_attach): Lint.
1138 * solib.c (find_solib): Handle shared libs version 2.
1140 Small fixes from David Wood:
1142 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1146 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1147 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1149 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1150 chars_per_line is at maximum (user typed `set width 0'). Fix
1151 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1153 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1155 * coredep.c: include ptrace.h where necessary.
1156 * mipsread.c(parse_lines): fix unsigned char problem that was
1157 messing up line numbers on SGI's and possibly other MIPS based
1159 * infrun.c (child_create_inferior): use better test to check
1160 return val from setpgrp().
1161 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1162 for sgi/irix support.
1164 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1166 * mipsread.c (parse_symbol): Put non-static procedures
1167 in the global block.
1169 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1171 Patch together `text_start' and `text_end' for 29K port.
1173 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1174 variables and set them based on the exec file.
1175 * am29k-tdep.c: declare text_start.
1176 * valops.c (call_function_by_hand): declare text_end.
1178 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1179 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1180 because machines that do this will also have to know to
1181 set NEED_TEXT_START_END. Besides, it was a redundant way to
1183 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1184 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1185 NEED_TEXT_START_END.
1187 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1189 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1191 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1192 Pass MUNCH_DEFINE to munch whenever we run it.
1193 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1194 format string; use 0x%x instead.
1195 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1196 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1197 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1198 * inflow.c: Handle `short' process group IDs.
1199 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1200 and check for ptrace errors.
1201 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1202 (coff_symfile_init): Initialize text_bfd_scnum.
1203 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1204 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1205 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1206 Merge target arm case with other "easy" cases. Add target
1207 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1208 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1210 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1211 * munch: Cope with RT/PC putting fns in data segment.
1212 Restore ability to override `nm' by specifying MUNCH_NM.
1213 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1214 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1215 and remote-adapt. Remove encapsulated coff #define's (the
1216 support should go in BFD, and gdb shouldn't know or care).
1217 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1218 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1219 * tm-29k.h: Update BADMAG (though it should go away).
1220 Allow the register definitions to be overridden in another
1221 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1222 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1223 DUMMY_SAVE_GR96, for handling kernel calling conventions
1224 that use GR64+ rather than GR96+.
1225 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1226 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1227 overrides various things.
1229 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1230 child_attach does, making a clean stop in the newly attached
1232 * remote-eb.c: Lint.
1234 * coffread.c: Make coffread independent of any particular
1235 variant of COFF. Avoid #include-ing any particular one except
1236 internalcoff.h. BFD now passes key values for symbol reading
1237 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1238 and the symbol masks and shifts); use them.
1239 Remove obsolete end_of_text_addr.
1241 * exec.c: Remove unused include files.
1243 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1245 * Makefile.in (documentation targets): Pass $(M4).
1246 Bugfix from eggert@twinsun.com (Paul Eggert).
1248 * stack.c (down_silently_command): Check for stack existence.
1250 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1252 * Makefile.in (VERSION): Update to 4.0.3.
1254 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1256 * core.c (core_file_command): Print frame at coredump with
1257 its level number, by calling print_stack_frame.
1258 * frame.h: Add selected_frame_level, print_stack_frame.
1259 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1260 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1261 Change print_sel_frame and print_selected_frame callers to
1264 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1265 * symfile.c (free_named_symtabs): Ditto.
1266 * main.c (main): wrap_here needs an arg.
1267 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1268 (solib_add): Avoid noise.
1269 (solib_create_inferior_hook): Lint.
1270 (sharedlibrary_command): Move dont_repeat to here.
1271 * utils.c (error): Call wrap_here to force buffered output.
1273 Small patches from Peter Schauer:
1275 * coffread.c (start_symtab): Free any existing line_vector before
1277 (read_coff_symtab): Ditto for type_vector.
1279 * source.c (lines_to_list): New variable, replacing function.
1280 (all uses): Use as variable.
1281 (_initialize_source): Add 'set listsize' and 'show listsize'.
1282 * utils.c (lines_to_list): Remove function.
1283 * stack.c (print_frame_info): Use as variable.
1284 * defs.h (lines_to_list): Remove declaration.
1286 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1288 * breakpoint.c (insert_breakpoints): Restore warning about
1289 the program might be running in another process, but only for
1290 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1291 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1293 * utils.c (error): if error_pre_print is set, print the string
1295 * main.c (main, print_gnu_advertisement, print_gdb_version):
1296 Reformat legalese so it always prints, but acts as an "I'm here"
1297 message while symbols are being read. If any errors occur,
1298 print a few newlines to set off the message and start it at the
1299 left margin. Remove mention of "help" command, and don't yak
1300 about symbol reading.
1301 (catch_errors): Error string is now printed first in case of
1303 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1304 suggest the "help" command.
1306 * Makefile.in (VERSION): Set to 4.0.2.
1308 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1310 * .gdbinit: Remove useless "rr" command. Set complaints
1311 to 1 for people debugging gdb.
1313 * breakpoint.c, remote-vx.c: Reword strings printed by
1314 catch_errors callers.
1316 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1318 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1319 (Fix from kenc@viewlogic.com.)
1321 Fix some infrastructure to be able to cope with host and target
1322 machines with different sized basic types (ints, ptrs, etc).
1323 (Idea from pierre@la.tce.com (Pierre Willard).)
1325 * values.c (value_from_longest): Rename from value_from_long.
1326 Handle pointer types as well as integers, so that targets with
1327 different pointer sizes from the host can be accomodated.
1328 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1329 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1330 uses of value_from_long to value_from_longest.
1331 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1332 the correct pointer type to value_from_long{est}.
1334 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1336 * remote-vx.c: Remove obsolete code for calling functions via
1337 vxworks kludge interface (it referenced value_from_long).
1339 * valops.c (value_string): Find malloc with lookup_misc_func, not
1342 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1344 Make writing to files work properly. (Fixes to BFD are also needed.)
1346 * core.c (core_open): Open file ourselves, read or r/w, depending on
1347 write_files. Use bfd_fdopenr.
1348 * gdbcore.h (write_files): New variable.
1349 * exec.c (write_files): Define variable, add set&show for it.
1350 (exec_file_command): Use write_files to open for read or r/write.
1352 Make shared library reading happen automatically. These changes
1353 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1355 * inferior.h (stop_soon_quietly): Add to exported variables.
1356 * infrun.c (child_create_inferior): call solib hook, if defined.
1357 (child_attach): call solib hook, if defined.
1358 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1359 (find_solib): Use lookup_misc_func rather than hand-rolled.
1360 (symbol_add_stub): New stub for catch_errors.
1361 (solib_add): Avoid output if !from_tty. Catch errors rather
1362 than just calling symbol_file_add and bombing.
1363 (solib_create_inferior_hook): Interface with the target process
1364 to let it read and alloc shared libs, then figure out what it did.
1366 * core.c (validate_files): Fix typo, soften warning.
1367 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1369 * utils.c (fputs_demangled): Avoid duplicate printing if
1370 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1372 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1373 (Fix from pierre@la.tce.com (Pierre Willard).)
1375 * main.c (catch_errors): Change argument to a char * from an int,
1376 since a char * can point to a struct full of glop, but an int
1377 is not guaranteed to be able to hold a pointer.
1378 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1379 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1380 * core.c (core_open, solib_add_stub): Adapt.
1381 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1383 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1385 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1386 by adding .NOEXPORT target.
1388 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1392 * Makefile.in (VERSION): Roll to 4.0.
1393 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1395 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1397 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1400 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1403 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1405 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1406 reflect above name change
1408 * WHATS.NEW: correct pointer to refcard.
1410 * doc/gdb.texinfo: update New Features, Installing
1412 * doc/gdbint.texinfo: add short description of configure +template
1414 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1416 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1418 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1420 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1421 tar file, add dependencies for referenced doc files.
1423 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1425 * coffread.c, symfile.c, stack.c: saberized.
1427 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1429 * doc/refcard.tex: permuted Essential Commands sec
1431 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1433 set/show symbol-reloading
1434 default set complaints 0
1436 RET-repeat disabled after prompted long displays
1437 processID (attach) interpretation of 2nd GDB cmdline arg
1439 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1441 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1442 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1443 breakpoint.c, main.c: lint.
1445 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1447 Install new configuration scheme for GDB and friends.
1449 * config.sub: Translate ordinary names to three-part names.
1450 * configure: Use three-part names internally.
1451 * configure.in: Translate three-part names to filenames.
1453 * README, WHATS.NEW: Update for gdb-4.0.
1454 * Makefile.in: Roll VERSION to 3.99.
1456 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1458 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1459 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1460 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1461 to single structures rather than arrays; when passing
1462 their address, use &. This avoids trouble with bdead compilers.
1463 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1464 instead. This avoids portability headaches.
1465 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1467 * source.c (open_source_file): Avoid ANSI const bdeath by
1468 skipping declaration and then casting result value.
1469 * tm-hp300bsd.h: Clarify comment.
1470 * utils.c (strstr): Result is const char *; ANSI bdeath.
1471 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1472 since system include file defines it differently from "defs.h",
1473 though the two are equivalent for our purposes.
1474 * tconfig/hp300bsd: Add m68k-tdep.o.
1476 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1478 * tconfig/sun*4: Remove warnings about system assembler.
1480 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1482 * mcheck.c: Avoid warning about undeclared abort fn.
1483 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1484 it causes recursive calls to error() when used in cleanups.
1485 To do so requires that we make it a function, so we do.
1486 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1487 * utils.c (do_cleanups): Remove the current cleanup from the
1488 chain *before* calling it, in case error() is called from it.
1489 The result won't be pretty, but won't be an infinite loop either.
1491 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1493 * dbxread.c (read_struct_type): Grok anon structs for C++.
1494 (vb_name, vptr_name): Null terminate these strings.
1496 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1498 Minor bug fixes from BSD Net2 gdb:
1500 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1501 returns 0, there is no previous frame.
1502 * breakpoint.c (commands_command): If !from_tty, don't call
1503 input_from_terminal_p().
1504 * dbxread.c (record_misc_function): Speed up slightly.
1505 (compare_psymbols): Ditto.
1506 * infcmd.c (do_registers_info): Take a second argument to
1507 determine whether to print float registers. "info registers"
1508 does not do so anymore. "info all-registers" does, now.
1509 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1511 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1512 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1516 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1517 executing_breakpoint_commands if we are interrupted by error.
1518 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1519 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1520 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1521 catch_errors() so we can setup the frame regardless of whether
1522 the shared libs work.
1523 * ieee-float.c (double_to_ieee_extended): Get exponent from
1524 right place in little-endian systems. From John Carey.
1526 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1528 * main.c: Remove unused terminating_signals and catch_termination().
1529 (long_options): Terminate with a zero element.
1530 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1531 (gdb_readline): Make call-compatible with readline.
1532 (init_signals): Improve comments re vfork vs. signal.
1534 * utils.c (prompt_for_continue): Use new gdb_readline().
1535 If we prompt for continuation, we don't let CR repeat the previous
1536 command, once we get back to a prompt. It's too easy to keep
1537 hitting CR, expecting "--more--" prompts, and have some long
1538 command start repeating on you.
1540 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1542 * blockframe.c (frameless_look_for_prologue): Speed up by
1543 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1544 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1545 Define two variants, one faster.
1546 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1547 and return zero, rather than giving an error.
1548 (setup_arbitrary_frame): Initialize the PC in the new frame.
1549 (skip_prologue): Add a second arg saying whether we're just
1550 checking for a frameless function or not.
1552 * core.c (core_open, core_close, core_xfer_memory): Move
1553 section table pointers and bfd* into the target_ops.
1554 (core_open): Allow errors in shared lib reading, etc.
1555 (core_files_info): Describe shared library sections.
1557 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1558 exec_files_info, set_section_command): Move section table
1559 pointers and bfd* into the target_ops.
1560 (add_to_section_table): Add BFD to section table.
1562 * target.c (target_xfer_memory, target_info): Pass target to
1563 xfer_memory and target_info functions.
1566 * gdbcore.h: Move struct section_table.
1567 * target.h: New home of struct section_table.
1569 * solib.c (solib_add): New argument is the target_ops whose
1570 section list is to be added to, if any. Reallocate the
1571 sections in that target to add any that come from shared libs.
1572 (throughout) so_sections renamed to sections.
1573 (solib_xfer_memory): Deleted.
1574 * tm-sunos.h (SOLIB_ADD): Add target argument.
1575 (SOLIB_XFER_MEMORY): Delete.
1577 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1578 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1579 from target_ops. It's the same on all targets. Add two section
1580 pointers to target_ops.
1582 * stack.c (find_relative_frame): Dump ancient algorithm for
1583 "down", just use handy "next" pointers.
1584 (frame_command): Don't error if there is no stack; let user
1587 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1588 modifies static state in the parent process; new_tty itself
1589 runs in the child and modifies the child's file descriptors
1590 to match the saved static state.
1591 * infrun.c (child_create_inferior): Call new_tty_prefork,
1594 * infptrace.c (child_xfer_memory): Add ignored target arg.
1595 * remote-eb.c (eb_xfer_inferior_memory): ''
1596 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1597 * remote-vx.c (vx_xfer_memory): ''
1598 * remote.c (remote_xfer_memory): ''. Rename from
1599 remote_xfer_inferior_memory.
1601 * main.c (main): Only try to attach "corefile" argument if
1602 it starts with a digit.
1604 * symfile.c (symbol_reloading): New "set/show" variable.
1605 (symbol_file_add): Shorten message about symbol reading.
1606 (add_symbol_file_command): Merge with add_syms_addr_command,
1607 since this should work on all targets now.
1608 (stop_whining): Default to zero, to shut up complaints
1609 about bad symbol tables on many systems.
1610 (free_named_symtabs): Just exit unless symbol_reloading.
1612 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1613 and add comment explaining shared library screw.
1615 * source.c: #if defined => #ifdef.
1617 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1619 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1621 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1623 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1624 (doc/Makefile knows how to make one for local config)
1626 * Makefile.in: use doc/Makefile for doc targets
1628 * doc/Makefile: GDB documentation now has its own Makefile
1629 doc/refcard.tex: renamed from "gdbrc.tex"
1630 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1631 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1634 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1636 * values.c (baseclass_addr): When reading target memory, use the
1637 length of the basetype, not the upper type. We've only malloc'd
1638 enough space for the basetype, leading to errors in free().
1640 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1641 ends up as a function specially, since we know the actual type of
1642 the pointed-to address. This (somewhat) fixes display of
1643 expressions that include misc_function_vector names. Try `cond 1
1644 !strcmp("a","b")' then `i b'.
1646 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1647 The child can be proceeded from inside wait_for_inferior in
1648 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1649 getting skipped in that case.
1651 * expprint.c (print_subexp): Use filtered output, since the
1652 subroutines we call use it, otherwise the output is horribly
1653 mangled, since output of wrappable stuff comes out late.
1655 * Makefile.in: Bump VERSION to 3.98.1
1657 * infrun.c (child_create_process): Use execlp to find the
1658 shell to exec our target program. This requires some fiddling
1659 with `environ' since there is no execlpe().
1661 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1663 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1664 Minor rearrangement of refcard permits two new make targets--
1665 gdbrc.dvi DVI output for refcard, using CM fonts
1666 gdbrc.ps PostScript refcard, using PS fonts
1668 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1672 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1673 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1675 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1677 * doc/gdb.texinfo: last changes for release.
1678 Minor typo and formatting fixes; incorporated most fixes remaining from
1679 filed mail commenting on earlier drafts.
1681 Added warnings: pipes don't work in run command;
1682 conditions are converse of assertions;
1683 step over fn without debug info goes to next fn;
1684 vars may have "wrong" values near fn entrance, exit
1686 Added example from Kingston on printing repeated nonadjacent values
1688 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1689 shell mode for signals
1691 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1692 doesn't sound so much like its parent "Stopping and Continuing"; also
1693 moved entries on continue to top of section, so they don't get lost.
1695 Improved installation directions in appendix, added manual formatting
1698 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1700 * configure.in: Remove xm.h and tm.h even if we aren't linking
1701 new ones, so "./configure sun4; ./configure none" does the right
1702 thing. Assume that alldeps.mak and depend are already built in
1703 srcdir, and avoid running "make" (particularly "make depend",
1704 which involves "gcc") from inside configure. Build Makefile
1705 directly rather than building Makefile.conf first.
1706 * configure: Regenerate with above changes.
1707 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1708 to 3.98. Revise gdb.tar.Z procedure to produce a file
1709 called gdb-$(VERSION).tar.Z but which unpacks into a
1710 directory called "gdb". Move non-source files out of
1711 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1712 (depend): Don't try to do "gcc expread.y".
1713 (expread.o): Update dependencies by hand.
1715 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1718 Fixed a variety of small typos that prevented info from formatting
1719 cleanly; altered too-long heading for GPL Appendix, as discussed
1720 w/RMS; Changed date on cover to July 91.
1722 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1725 (1) Applied some fixes due to comments from Larry Breed (easier ones
1726 through chapsec 5.2)
1727 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1728 it's broken in latest texinfo
1729 (3) Introduced *some* use of [] for optional arguments, where
1730 explanation is not simpler by listing cmd w arg and cmd w/out arg
1731 separately. Still not using @deffn.
1732 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1733 couple of headings are too long. Need patches to texinfo or revision
1736 * Partial update to README (which still needs work for this
1737 release!): (1) use of configure corrected for new script,
1738 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1740 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1742 * symtab.c (lookup_symbol): Don't complain right off about
1743 no debug symbols; use the misc function vector first.
1744 (list_symbols): Use misc function vector to find symbols
1745 that don't have debug info, and print them.
1746 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1747 PC range doesn't match symtab PC range, as it does on the
1748 MIPS because our symtab reading isn't perfect.
1750 * dbxread.c (dbx_symfile_read): Make warning about
1751 "no debug symbols" slightly nicer.
1753 * source.c (select_source_symtab): If "main" symbol exists,
1754 but decode_line_spec can't find line info, don't just return
1755 a zero; try other source symtabs or give an error.
1757 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1758 their low addresses first, then rip through fixing high addrs.
1760 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1761 <runene@ifi.uio.no>.
1762 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1764 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1766 * Minor, mostly mechanical, cleanup of doc subdir for clean
1767 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1768 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1770 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
1772 Mostly MIPS and general symbol-reading fixups.
1774 * doc/gdbint.texinfo: Add documentation on symbol-reading
1777 * mipsread.c: Remove kludges around #include "ecoff.h".
1778 Remove redefinitions of a_magic, etc, no longer used.
1779 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
1780 Fix global overview comments to match symfile.c protocol.
1781 (mipscoff_new_init): Eliminate cur_hdr if we have one.
1782 (mipscoff_symfile_read): Eliminate unused code. Avoid
1783 sorting all the symtabs, when all we have read here is psymtabs.
1784 The symtabs are sorted as they are created anyway. Tell
1785 condense_misc_bunches whether we're mainline.
1786 (psymtab_to_symtab_1): Pass filename when recursing, to make
1787 stack trace more informative.
1788 (parse_partial_symbols): Assume cur_hdr as argument.
1789 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
1790 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
1791 the TYPE_NAME of char *, since that's done in symfile.c.
1792 (free_numargs, parse_symbol, add_symbol, add_block,
1793 shrink_linetable): Declare these fns void.
1794 (upgrade_type): Convert tree of if's to switch. Clean up
1795 bogus "off == 0" handling with a complaint. Avoid setting
1796 field bitpos and bitsize of array with lower and upper bounds.
1797 Check specified bitsize of elements against their actual type's
1798 bitsize, and complain if different. Complain about unknown
1800 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
1801 (psymtab_to_symtab_1): Print names of subsidiary files that
1802 are being read in. FIXME, we read far too many files. This code
1803 is not the problem, the problem is in parse_fdr where the psymtabs
1805 (cross_ref): Result should indicate that we used one aux entry
1806 normally, or two if we encountered a "next" entry. This used
1807 to leave the caller pointing at the wrong aux entry.
1808 (add_symbol): If overflowed cur_block, reallocate it larger,
1809 chase all pointers to it, and complain(), rather than clobber memory.
1810 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
1811 (new_field): Only allocate one field initially, not two.
1812 Pull ++ out of macro argument. Simplify.
1813 (_initialize_mipsread): Avoid initialization of importd
1814 global_psymbols and static_psymbols.
1816 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
1817 to properly set pst->symtab; avoid searching for it.
1818 (symfile_fns): Improve comments, add a FIXME.
1819 * dbxread.c: Update comments to reflect symfile protocol.
1820 (read_ofile_symtab, end_symtab): Return the symtab.
1821 (psymtab_to_symtab_1): Set pst->symtab.
1823 * coffread.c (coff_symfile_read): tell condense_misc_bunches
1824 whether we're mainline.
1826 * symfile.h (sym_fns): Remove unused sym_discard member.
1827 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
1829 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
1830 the environment variable is not.
1831 * infcmd.c (finish_command): Use filtered printfs.
1832 * cplus-dem.c: Add struct tags to a few unnamed structs.
1833 * valops.c (value_coerce_array): Improve comments.
1834 * valprint.c (type_print_varspec_suffix): Print array size only
1835 if greater than zero.
1836 * m88k-tdep.c: Shift some lines left by one space, that had
1837 apparently been trashed at some point.
1838 * TODO: More things to do, a few got done.
1840 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1842 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
1843 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
1845 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
1846 * expread.y, findvar.c, symmisc.c: Ditto.
1847 * printcmd.c (address_info): Update printed forms of LOC_
1848 symbols. Elim LOC_EXTERNAL.
1849 (print_frame_args): Keep track of param stack offsets before
1850 re-looking up to find the local register param is kept in.
1852 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
1853 Further integration of mipsread into gdb. Eliminate unused
1854 routines, duplicate declarations. Handle static symbols in
1855 psymtabs as well as external symbols. When reading symtabs,
1856 insert symbols into the correct block (global, static, or a local
1858 (read_mips_symtab, parse_partial_symbols): Don't pass useless
1860 (mipscoff_symfile_read): Don't call select_source_symtab.
1861 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
1862 rather than SYMBOL_VALUE.
1863 (parse_external): Comment clobbering of top_stack.
1864 (parse_partial_symbols): Update comments. Allocate and parse
1865 static symbols as well as external symbols. FIXME, enum values
1866 are not handled in this pass, but should be. Inline new_psymbol.
1867 Use SYMBOL_VALUE_ADDRESS.
1868 (psymtab_to_symtab_1): Read symbols into global static block
1869 by default (until enter some function's local block context).
1870 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
1871 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
1873 * source.c (select_source_symtab): Select a source symtab
1874 from either the symtabs or, failing that, the psymtabs.
1875 (list_command): Update error message.
1876 (forward_search_command, reverse_search_command): Use getc, not
1877 fgetc, for speed. FIXME, add comment about buffers that die if
1878 overrun by long line.
1880 * values.c (unpack_field_as_long, modify_field): Avoid shifting
1881 by an entire word, which is not portable, if we have a 32-bit
1882 field. (Code in dbxread.c already turns such bitfields, if
1883 aligned, into ordinary ints, but fixing this will help for other
1884 symbol formats and for future changes.)
1885 * core.c (core_open): Handle ANSI const brain death.
1886 * utils.c (vprintf): Fix varargs typo.
1888 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1890 * findvar.c (find_var_value): Handle &function better.
1891 * TODO: Document work needed on &fn and &array.
1892 * printcmd.c (print_address_symbolic): New arg is the prefix
1893 to print if a name is printed.
1894 (print_address_demangle): Honor "set print address" now.
1895 Use new arg above to improve spacing of output.
1896 * valprint.c (val_print): When printing function pointers,
1897 print symbolic form too.
1898 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
1900 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1902 * core.c (memory_error): Reword error msg to mislead less.
1904 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
1906 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
1907 parse_partial_symbols): Use newer BFD internals (external_filehdr
1908 and external_aouthdr), byte-swap the fields that we care about
1909 before using them, and make the file header data local to
1910 read_the_mips_symtab rather than global.
1912 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
1914 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
1915 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
1917 * main.c (command_line_input): Flush stdout and stderr
1918 before every call to readline. This reportedly fixes a bug
1919 that comes up in Sys V running emacs-gdb and/or xxgdb,
1920 when stdin/out are pipes or sockets.
1922 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1924 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
1925 Avoid declaring Makefile dependencies, because GNU Make stupidly
1926 tries to update it if we do.
1928 * coffread.c: Revise for minor changes to bfd internal coff
1931 * configure: If -template= is given a relative path, make it
1932 absolute before recurring in subdirectories.
1934 * configure, configure.in, Makefile.in: Install "configure" script
1935 as replacement for config.gdb.
1936 * config.gdb, Makefile.dist, Makefile.sdir: Remove
1937 * README: Update for configure, mostly. FIXME.
1939 * Add dec3100 as equivalent to littlemips. Indicate in all host &
1940 target config files that they are for the host. When the lines
1941 get copied into the Makefile, this makes it more obvious what's
1944 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1946 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
1947 tabs, which end up in the disassembler output inadvertently.
1949 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1951 Make it compile cleanly in an ANSI GCC2 environment.
1953 * blockframe.c: <stdio.h>
1954 * cplus-dem.c: free takes a void *, ifdef __STDC__
1955 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
1957 * defs.h (alloca): Avoid doing anything if alloca already def'd.
1958 * stddef.h, stdlib.h: Remove these files.
1959 * symtab.c: Avoid declaring qsort, close.
1960 * symfile.c: Avoid declaring close.
1961 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
1962 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
1964 Assorted other changes.
1965 * dbxread.c: include "libaout.h", not "liba.out.h".
1966 * printcmd.c (print_frame_args): Set recurse properly for
1967 indentation of struct and array parameters.
1968 * valops.c (value_cast): Allow cast to void.
1969 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
1970 single_step() in a target-independent fashion.
1971 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
1972 set up to be ready to continue. This makes us target independent.
1973 * infptrace.c (child_resume): Remove call to single_step; now
1974 can single step a SPARC target of any kind.
1976 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1978 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
1979 docn into separate sections---basically chapters, plus two loose
1980 pieces that can be configured to go in different places. This
1981 allows GNU m4 to preprocess the manual without coredumping.
1983 * Makefile.dist: tell TeX where to find texinfo.
1985 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1987 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
1988 the new target "rdl-apps.texinfo" which captures the Makefile
1989 variable that records where to find the Readline libraries.
1991 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
1993 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
1994 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
1995 * defs.h (const, volatile): Only define if not already defined.
1996 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
1998 * README: Update for release 3.95.
1999 * config.gdb: Don't create readline dir in subdir builds.
2000 * main.c: Include with "..." form for non-system include files,
2001 so "gcc -MM" for "make depend" works.
2002 Include readline files with "...h" rather than <readline/...h>.
2003 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2005 * coffread.c: Undo minor damage done by Rich Pixley. Use
2006 different internal and external representations of COFF
2007 data structures. Use new BFD routines for swapping them in and
2009 * symfile.c (free_named_symtabs): Avoid freeing file names that
2010 are null or empty. Old i960 tools seem to produce files that
2011 claim to have empty names, causing each successive file read
2012 to blow away the previous one.
2013 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2014 Move deferred_stores to top of file, but don't separate its
2015 #define's from its variable. Add commentary.
2016 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2017 favor of keeping the (working) config.gdb. Move readline

2032 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2033 applied various small fixes due to or inspired by RMS comments
2035 * doc/gdb.texinfo: finished using all RMS comments, save those for
2036 appendices on readline and cmd history (which are in other source
2039 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2041 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2042 chapter 9; (2) documented 'break' command's menu mode for
2043 overloaded names, in response to hgs problem report C++ p-31
2045 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2047 * doc/gdb.texinfo: (1) better introductory example; (2) more
2048 consistent use of @code, @samp, @file, @kbd throughout; small
2049 cleanups to first three nodes; (3) new "Contributors" node;
2050 (4) Appendix, Renamed Commands; (5) divert specialized startup
2051 instructions to "Targets" chapter for generic manuals, while
2052 leaving them up front for manuals specific to specialized
2053 environments; (6) apply fixes from RMS comments through chapter 4.
2055 * pretex.m4: modify explanatory text slightly (and redefine
2056 "regexp") to keep GNU m4 from complaining. (It still crashes
2057 later, but one step at a time...)
2059 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2061 * readline/readline.c (update_line): Avoid dereferencing a pointer
2062 before comparing it to its bounds. Saber caught this.
2063 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2064 and only set PC if tgetstr returned non-null. Saber caught this.
2066 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2068 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2069 stuff for config manual) here where it counts; updated
2070 to use new subdir structure (gdb/doc/).
2072 * Makefile: generated from above via
2076 * gdbint.texinfo: added instructions on generating gdb.info* files
2077 locally for release. These are ordinary info
2078 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2079 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2080 to generate these, so we distribute them already formatted.
2082 * gdb.texinfo: included full Info node and menu crud (as generated
2083 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2085 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2086 put in comments-for-future gdb.info target (one day makeinfo will
2089 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2091 * gdb.texinfo: Updated to include new or old undocumented
2092 commands, at least the following (perhaps some others I forgot to
2093 record): info f, info float, info path, info program, info s, info
2094 set, info source, info terminal, info types, info user, set/show
2096 Also covered all recent GDB command renames for v4.
2098 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2100 * mipsread.c: Rather than keeping count of how many symtabs
2101 and psymtabs we have, for sorting purposes, count them when
2102 we need to sort. This fixes bug in rereading of symbol tables.
2104 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2106 * infcmd.c: renamed "info path" to "show paths"

2121 symtab.h, target.c, target.h: Lint.
2122 * core.c: setup and select frame after reading shared libs,
2123 else reading shared libs will clobber them. Lint.
2124 * utils.c (error): Force out any buffered wrap text.
2126 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2128 * remote.c: Remove decls of memory_insert_breakpoint
2129 and memory_remove_breakpoint, no longer used. (Suggestion of
2132 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2133 to make it easier to interface to "configure"'d libraries.
2135 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2137 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
2138 aliases for set/show print.

2650 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
2651 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.

2677 (free_symtab): Make non-static.
2678 * symtab.h (free_symtab): Declare as exported void fn now.
2679 * dbxread.c (end_symtab, end_psymtab): Change comments.

2681 command is add-symbols.
2682 * target.c (dummy_target): Permit add_syms_addr_command.
2684 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2686 Permit symbols to be superseded when new symbol files have
2687 been read in, particularly for VxWorks.
2689 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
2690 to the main file, as well as to include files. Also, put global
2691 functions into the global psymtab, to make "i fun" work.
2692 (end_psymtab): Free named symtabs and psymtabs for a file, once a
2693 new psymtab for it has been read.
2694 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
2695 a file, once a new symtab has been read for it.
2696 * mipsread.c: FIXME. We need to do the same for MIPS, but it
2697 looks harder to determine the top-level block before it's been
2698 queued to the psymtab list.
2700 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
2701 If we have wiped out any old symbol tables, clean up at end of
2703 (symbol_file_command): Don't reference symfile_fns if it's zero.
2705 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
2706 defines for the blocks of a blockvector that contain global and
2707 file-static symbols and the first of the smaller scope contours.
2708 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
2709 decode_line_1, make_symbol_completion_list): Use the above.
2710 * coffread.c (end_symtab, patch_opaque_types): Ditto.
2711 * dbxread.c (end_symtab): Ditto.
2712 * expread.y (block): Ditto.
2713 * mipsread.c (throughout): Ditto.
2714 * symmisc.c (free_named_symtabs): Ditto.
2716 * symtab.c (list_symbols): Process the first symbol of the
2717 static psymbols list.
2718 (types_info): Restore this function from its untimely #if 0.
2719 It's not perfect, but it is better than nothing.
2720 (_initialize_symtab): Restore "info types".
2722 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2724 * m68k-stub.c: Remote stub for 680x0's, created from
2725 rem-m68k.shar (which is removed).
2726 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
2727 Remove RCS log stuff now that we use CVS and it blows our diffs.
2729 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2731 * symmisc.c (free_named_symtab): Make it work, in its current
2732 kludgy fashion. Change result to indicate if we blew away bkpts.
2733 * dbxread.c (end_symtab): Accumulate result from
2734 free_named_symtab and print warning if we blew user's state.
2735 * symfile.h: free_named_symtab now returns an int.
2737 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
2739 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
2740 is the first symbol read, even if not mainline.
2741 (dbx_psymtab_to_symtab): symfile might be zero, cope.
2742 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
2743 (set_section_command): New command ("section xxx yyy" -- should
2744 be renamed to "set section xxx yyy" FIXME) which sets the
2745 base address of a section of the exec file, overriding the
2746 virtual address that BFD reports.
2748 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2750 * exec.c: Add add_syms_addr_command to exec_ops, so you can
2751 load symbols at any address while examining an exec file.
2753 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2755 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
2756 for printing the float info is host-dependent, not
2757 target-dependent. FIXME.
2758 * i386-pinsn.c: Move #includes to top, remove useless ones.
2759 * i386-tdep.c: Don't bother including <.../reg.h> since we
2760 don't use it (and it doesn't exist on host systems).
2762 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
2763 Convert negative numbers properly.
2764 (ieee_test): Make numbers really random; fix format arg.
2766 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
2767 * core.c (core_detach): Unpush core_ops, which might not be on
2768 top. We used to just pop the top, which broke things. Don't
2769 need dont_repeat() any more.
2770 (core_file_command): Psst! Don't repeat it.
2771 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
2772 * expprint.c (print_subexp): Avoid switch fallthru on
2773 BINOP_ASSIGN_MODIFY, so we can print += and such.
2774 * frame.h: Fix typo.
2775 * inflow.c (kill_command): After killing inferior, print our
2776 current frame in the core file, if we have one.
2777 (generic_mourn_inferior): When inferior dies, either select
2778 the current frame (in the new target, e.g. core file), or
2779 set both the current and selected frames to NULL.
2781 Changes from Peter Schauer.
2783 * infptrace.c: Avoid <sys/ptrace.h> on USG.
2785 * Make all file names fit in 14 characters (sigh and damn!):
2786 mv hp300hpux-xdep.c hp300ux-xdep.c
2787 mv symmetry-xdep.c symm-xdep.c
2788 mv symmetry-tdep.c symm-tdep.c
2789 mv convex-opcode.h convx-opcode.h
2790 mv tm-vxworks960.h tm-vx960.h
2791 mv tm-vxworks68.h tm-vx68.h
2792 mv Makefile.srcdir Makefile.sdir
2793 mv gdb-int.texinfo gdbint.texinfo
2794 mv remote-sa.m68k.shar rem-m68k.shar
2795 mv remote-multi.shar rem-multi.shar
2796 * Makefile.dist, README, config.gdb, convex-pinsn.c,
2797 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
2798 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
2801 * command.c (user_info_1, user_info): New command for listing
2802 the user-defined commands.
2804 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2806 * dbxread.c (really_free_pendings): Clear file_symbols
2807 and global_symbols after freeing them; otherwise, running
2808 this function twice (if it appears twice on the cleanup
2809 chain), we try to free things twice.
2811 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
2812 based on text_addr (the address of text in core), not on addr (the
2813 offset between text in the .o file and in core). This change
2814 is from Peter Schauer.
2816 * main.c: Define ALL_CLEANUPS as a cast of zero.
2817 (return_to_top_level): Use it.
2818 (main): Do all cleanups after each command run as part
2819 of the gdb startup sequence. Also do all cleanups before
2820 entering the command loop, and every time we exit the command
2821 loop and reenter. Before, the cleanups from the startup sequence
2822 were being left undone until the first error!
2823 (command_loop): Rename do_nothing cleanup to command_loop_marker
2824 so we can see it easily when examining the cleanup chain.
2825 (init_signals): Add another do_nothing for signal handling.
2826 (quit_command): Only try to kill target if it has execution.
2827 Problems in the target stack got us into a state where
2828 inferior_pid was nonzero but none of the targets had execution.
2829 In this state you couldn't exit gdb.
2831 * dbxread.c: Two changes from Peter Schauer.
2832 (echo_command): Fflush output after an echo command.
2833 (show_history): Pass all args to cmd_show_list.
2835 * utils.c (init_malloc): Call mtrace to turn on tracing
2836 if the environment variable MALLOC_TRACE is set to a file name.
2837 * mtrace.c: Add source file which provides a log of every malloc,
2838 free, and realloc to a trace file.
2839 * mtrace.awk: Add source file which analyzes the trace file.
2840 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
2841 (VERSION): Roll to 3.94.3.
2843 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
2844 (check_duplicates): Don't bother with watchpoints.
2845 (set_raw_breakpoint): Comment about danger of this routine.
2846 (watch_command): Parse and eval all args before calling
2849 * solib.c (find_solib): Avoid error in referencing memory to
2850 see if any more shared libraries have been added. This is
2851 particularly useful if the target has terminated. Bug reported
2854 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
2855 in bringing up 3.94.2 on the Sun-3.
2857 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
2858 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
2859 expression (in scope) before reenabling watchpoint.
2860 * signame.c (init_sigs): Add missing declaration of i, fix
2861 sys_siglist declaration.
2862 * source.c (list_command): Fixed range computation to use
2864 * stack.c (backtrace_command): Do not allow command if target has
2865 no stack, print informative error message.
2866 * target.c (target_command): Do not write into command line
2867 because this fails if the target command is used in a user defined
2868 command. [This change was enhanced by gnu to support any-
2869 unique-prefix matching on target names.]
2870 * valops.c (value_struct_elt): Avoid infinite loop on an
2871 erroneous attempt to print the member of function (try p main.p).
2873 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2875 * expread.y (name_no_typename): Avoid reduce/reduce errors
2876 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
2877 Since the GDB parser really doesn't use name_no_typename in a
2878 name-only context, the parser can't tell the diff between
2879 names and numbers here. Avoid allowing a name_no_typename
2880 to be a NAME_OR_*INT to resolve the conflict.
2882 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2884 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
2886 * valprint.c (val_print_fields): bitfield printing didn't handle
2887 byte order. Indirect through a few more fns to cope.
2889 * values.c (modify_field): also cope with byte order.
2891 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2893 Cleanup for release 3.94.2:
2895 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
2896 include files. Roll version to 3.94.2.
2898 * coffread.c (init_stringtab): Read length into unsigned char
2899 array before swapping; don't assume 32-bit longs.
2901 * target.c (target_info): Don't bother with get_sym_file, just use
2902 the symfile global variable.
2903 * symtab.h, symfile.c (get_sym_file): Delete it.
2905 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
2906 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
2907 (read_type): Replace one more error() with complain().
2909 * mipsread.c (parse_partial_symbols): Replace printf with complain.
2911 * i960-tdep.c: Fix copyright attribution.
2913 * config.gdb: Quote all backquotes in doublequotes. You can
2914 quote me on that. BSD 4.4 shell found this one.
2916 * infptrace.c (throughout): The third argument to ptrace is an
2919 * infrun.c (wait_for_inferior): When program has terminated, we
2920 have to call target_terminal_ours before we pop that target off
2921 the stack (e.g. before a call to target_kill or
2922 target_mourn_inferior). This fixes problem where a program
2923 terminates, then GDB stops for (tty output) and you have to type
2924 "fg" to the shell to resume it. FIXME: This code for what to
2925 do after termination really should be in normal_stop instead.
2927 * gdbcore.h (read_memory_check): Change declaration; it changed
2930 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
2931 4.4 prereleases, this avoids a bug in their sgtty compatability
2933 * remote.c: Use terminal.h rather than hand-rolling the same.
2935 * signame.c, signame.h (psignal): Arg is unsigned, not int.
2936 * utils.c (strsave, strstr): Fix arg types.
2937 * valprint.c (val_print): lint
2939 MIPS symbol table support from Per Bothner:
2941 * symfile.c (symtab_fns): Remove initializer table that needs to
2942 be hacked for each new symbol file format supported.
2943 (add_symtab_fns): New function, chains symbol table
2944 handlers into the global list.
2945 (symfile_init): Search this list.
2946 * symfile.h: Add next pointer, declare add_symtab_fns.
2947 * coffread.c (_initialize_coffread): Call add_symtab_fns.
2948 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
2950 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
2951 symbol *). Thus, we no longer need the hack to trash
2952 pst->filename. Good, since that hack confused code in symfile.c!
2954 (reorder_symtabs, destroy_all_symtabs): Removed static
2955 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
2956 Instead, the latter now uses a temporary array (stack-allocated
2957 from an obstack, and then freed).
2959 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
2960 haven't been set in the outermost stBlock of a procedure. This was
2961 a problem with f77 binaries on Ultrix 4.?.
2963 (new_symtab, new_symbol, new_type): Continue changing code to use
2964 obstacks more and otherwise conform to dbxread internal style.
2965 Made the free_code of symtabs be free_linetable (as in dbxread)
2966 instead of free_contents. This implies memory leaks when reading
2967 a new symbol table, until the conversion is finished. Did change
2968 (struct symbol) and (struct type) to be allocated on the
2969 symbol_obstack. Blocks and blockvectors are among the things
2972 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
2973 tested much, but it solved one problem (reported by Meissner), and
2974 cleans up some other things. The problem happened when an
2975 included file contains actual code (functions) and not just
2976 definitions. The mips coff is a little inconvenient there, since
2977 it may cause a procedure to be mapped to the wrong psymtab.
2979 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
2980 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
2981 this will need work for the new core paradigm.
2983 Opcode patches from the net:
2985 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
2986 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
2987 missing altogether - they are added here. From Bruce Bauman.
2988 * mips-opcode.h: The low mask for C0 instructions was too small.
2989 From Garrett Lau. I modified the fix to check the entire 32-bit
2992 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
2995 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2997 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
2999 * dbxread.c (read_type): Pointer subtraction (value_sub in
3000 valarith.c) sometimes failed because the types of the
3001 pointers being subtracted were not identical.
3002 These differed because dbxread.c was allocating pointer types
3003 using dbx_alloc_type+smash_to_pointer_type instead of
3004 lookup_pointer_type. I failed to find a justification for the
3005 former, so I changed it to use the latter. Similarly, I
3006 replaced smash_to_function_type by lookup_function_type,
3007 and smash_to_reference_type by lookup_reference_type.
3009 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3010 _initialize_mipsread): corresponding changes.
3012 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3014 * source.c (mod_path): Do tilde_expand on each component of the path,
3015 rather than on the (list of) paths as a whole.
3016 (print_source_lines): Set first_line_listed in addition to
3017 current_source_symtab and current_source_line. If the source was
3018 not findable, after a "dir" command to fix the problem,
3019 a "list" would get the wrong lines.
3021 While I was there... (gnu):
3023 * dbxread.c (read_type): Change error to complaint.
3025 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3027 First attempt at detailed understanding of symbol table memory alloc.
3029 * dbxread.c (dbx_symfile_read): Free our string table if we
3030 aren't the mainline. Free the "info" struct since we're done with
3032 (init_psymbol_list): Free any previously allocated psymbol lists.
3033 (): FIXME: Should realloc-down the psymbol lists when done reading
3034 the main symbol file?
3036 * symmisc.c (free_symtab): Free fullname field too.
3038 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3039 (REGISTER_ADDR): Make result type unsigned int.
3041 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3042 define REGEX must also define REGEX1 (its dependency).
3044 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3046 * tconfig/i960: No longer works, points you at vxworks960 or
3049 * xgdb.c, XGDB-README: Remove file. Users can get the much
3051 * Makefile.dist: Remove all trace of xgdb.
3053 * breakpoint.c (breakpoint_1): Pass demangle arg to
3054 print_address_symbolic.
3055 (clear_breakpoints): Remove unused function.
3056 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3057 (breakpoint_re_set): Use catch_errors to do them all anyway.
3059 * gdb-int.texinfo (Host versus Target): Add section on what is
3060 a "host" feature versus what is a "target" feature.
3062 * infcmd.c (path_command, path_info): Handle the PATH variable
3063 (object search path) as conveniently as the source search path.
3064 * environ.c (set_in_environ): Set some vars in GDB's environment,
3065 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3066 * source.c (mod_path): New function, from guts of
3067 directory_command, modifies a path. Used by path_command.
3068 (directory_command): Call it.
3069 * defs.h (strsave): Declare.
3071 * utils.c (sevenbit_strings): Add new printing option.
3072 (printchar): Use it.
3073 (strsave): Provide this handy helper routine.
3074 (set_width_command): Rename set_screen_width_command.
3075 (_initialize_utils): "set screen-width" => "set width";
3076 "set screen-height" => "set height"; add sevenbit-strings.
3078 * infcmd.c (do_registers_info): Print floating point registers
3079 in raw hex as well as float format, regardless of whether it is
3080 a "virtual" convertible register.
3081 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3082 regs as a double, just in case it's being used that way.
3083 * values.c (unpack_long): Comment on array/function coercion.
3084 (unpack_double): Argument is in target byte order now. For
3085 integer arguments, just call unpack_long and float the result.
3086 * m68k-tdep.c: include defs.h for "const" handling.
3087 * remote-nindy.c: Use ieee-float stuff.
3088 (nindy_fetch_registers): Unpack double regs to host double, then
3090 (nindy_store_registers): Pack extendeds to host double, flip
3091 around by misusing unpack_double, send as target double.
3093 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3094 zero, as when stopped at the first instruction of a process.
3096 * blockframe.c: Fix filename in comment (param.h => tm.h).
3097 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3098 * tm-68k.h: Fix typos.
3100 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3102 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3104 * coredep.c (fetch_core_registers): Pass end-address of register
3105 section to register_addr as expected. Don't call supply_register
3106 if we'd just pass it garbage.
3108 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3110 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3112 * target.c (push_target, target_info): Cast enums to int for < or
3115 * stack.c (print_frame_info): Identify source file & line
3116 even if we can't print it.
3118 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3120 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3122 Clean up IEEE floating point support.
3124 * ieee-float.h: New file.
3125 * ieee-float.c: Write real routines to convert between host
3126 doubles and various target IEEE extendeds.
3127 * m68k-xdep.c: Eliminate assembler code for extended floats.
3128 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
3129 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3130 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3131 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3132 double_to_ieee_extended.
3133 * i960-tdep.c: Define ext_format_i960.
3134 * m68k-tdep.c: Define ext_format_68881.
3135 * sparc-tdep.c: Define ext_format_sparc, though unused.
3136 * Makefile.dist (HFILES): Add ieee-float.h.
3137 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3140 Obsolete the "coffstrip" program in favor of using BFD's strip.
3142 * nindy-share/coffstrip.c: Remove file.
3143 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3144 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3145 * tconfig/nindy960: Remove reference to coffstrip.o.
3147 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3149 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3151 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3152 * dbxread.c: Remove static symfile_bfd.
3153 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3155 * inftarg.c (child_detach): Pop the child_ops vector if the
3156 detach is successful.
3157 * remote-nindy.c (nindy_create_inferior): Don't push a new
3158 nindy_ops since nindy uses the same one for execution and memory
3160 * core.c (core_ops): Use child_attach and child_create_inferior
3161 rather than default attach and create_inferior functions.
3163 Handle floating point registers in core files.
3165 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3166 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3167 This version untested since BFD doesn't yet support sun3 core
3169 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3170 conventions. Fix comments and style. This version has not
3171 been compiled yet, since we have no HP inhouse.
3172 * core.c (get_core_registers): Look for two sections, ".reg"
3173 and ".reg2", and pass both to fetch_core_registers sequentially.
3175 Revise directory path yet again.
3177 * source.c (forget_cached_source_info): Not static any more.
3178 (init_source_path): New default source path is "$cdir:$cwd".
3179 (dir_command): Handle variable arguments ($cdir, $cwd).
3180 (source_info): Print "Compilation directory" rather than
3181 "Originally compiled in" to remind people of $cdir.
3182 (openp): If the path contains $cwd, use current directory.
3183 (open_source_file): If compilation directory is known, replace
3184 first $cdir in path with the compilation directory.
3185 (print_source_lines): Even if we can't print the lines, set the
3186 current symtab and line for future commands like "info source" or
3187 "breakpoint". Also, error message now contains the file name,
3188 line number, and file access error message.
3189 (_initialize_source): Fix help text to describe changes.
3190 * main.c (cd_command): Forget cached source info when we chdir.
3191 * utils.c (strstr): Add simple implementation.
3193 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3195 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3196 Byte-swap COFF symbol tables if necessary when reading them in.
3197 Use complain() to replace error message in one spot. Needs
3198 corresponding change in bfd/coff-code.h to make some symbol
3199 swapping routines non-static.
3201 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3203 Merge changes from Eirik Fuller, for UTek.
3205 * defs.h (errno): Add declaration.
3206 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
3207 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3208 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3209 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
3210 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
3211 declarations of errno.
3213 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3215 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3216 <rpc/rpc.h> and <rpc/types.h>.
3218 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3220 * i960-tdep.c (examine_prologue): Add new argument limit,
3221 which stops the scan at the end of the prologue, or at the PC.
3222 This fixes a problem where it walks down into the code for the
3223 user's statements if that code looks like function prologues.
3224 Mark Fox and I have been bouncing this code back and forth, making
3225 small changes to it. Callers changed to match.
3227 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3229 Cleanup for gdb-3.94 release final:
3231 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3232 the .c files from vx-share and nindy-share, from the various
3233 macros, since they are not found via ALLDEPFILES.
3234 (SFILES): Add tm-i960.h.
3235 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3236 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3238 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3239 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
3241 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
3243 * am29k-tdep.c: Add contribution line.
3244 (examine_prologue): Cache information about function prologues in
3245 the misc-function-vector to avoid lots of references over the
3246 serial line while examining instructions.
3248 * core.c (core_close): New function made from cleanup_core.
3250 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3251 remote-vx.c, remote.c, target.c, target.h,
3252 Update target_ops vector to add attach, close, and load entries.
3253 Use add_syms_addr_command, not add_file_addr_command, for
3254 add_file. Break out close routine from existing code.
3256 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3257 they are in an obstack.
3258 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3260 (define_symbol): Add symbol type parameter; change callers;
3261 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3262 it to influence the symbol class on the i960.
3263 (define_symbol): Swap LOC_CONST's into target byte order.
3265 * exec.c (exec_close): New function.
3266 (exec_file_command): Call it.
3268 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3269 Fix byte order of frame pointer.
3270 (read_var_value): Result of 0 if var's value can't be found,
3271 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3272 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3273 (locate_var_value): Use read_var_value and use its lazy address
3274 as the location of the var's value. Lint.
3276 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3279 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3280 obsolete Intel versions in favor of vxgdb versions.
3281 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3282 code dealing with byte order of values, which Intel did in host byte
3283 order rather than gdb-4's target byte order.
3284 (i960_frame_chain_valid): Move to nindy-tdep.c.
3285 (examine_prologue, skip_prologue, frame_find_saved_regs,
3286 frame_args_address, leafproc_return, saved_pc_after_call,
3287 pop_frame): Add vxgdb versions from Mark Fox.
3288 (examine_prologue, frame_struct_result_address): Add code
3289 to deal with the saved value of G13 (struct return address
3291 (frame_args_address): Modify Mark's version to prefer the
3292 saved value over the current value in the topmost frame.
3293 Cache result in the frame info to avoid performance hair in
3295 (print_fault): Add gdb960 code for printing faults.
3296 (_initialize_i960): Actually call check_host.
3298 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3299 add stub routines. FIXME, these currently just return zero!
3301 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3302 (attach_command): Call target_attach, not target_open, now.
3304 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3305 (child_attach): Rename from child_open.
3306 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3307 don't confuse it with a zero step_resume_break_address.
3309 * inftarg.c (child_detach): Eliminate inferior_pid test.
3310 (child_files_info): Clean up message a bit.
3311 (child_ops): Use child_attach, not child_open, to attach.
3313 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3314 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3315 findvar.c to here, since it depends on the contents of the
3316 shadow_contents of breakpoints, but keep if #if 0 since it is
3319 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3322 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3323 (ptype_command, display_command): Eliminate have_inferior_p and
3324 have_core_file_p in favor of target_has_stack or
3325 target_has_execution.
3326 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3327 code for actually finding the values of arguments, though we still
3328 keep track of the maximum stack offset for use in printing unnamed
3329 arguments. Handle missing FRAME_ARGS_ADDRESS.
3331 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3332 (struct nindy_regs): Define registers passed to/from nindy.
3333 (nindy_fetch_registers, nindy_store-registers): Translate between
3334 nindy and GDB formats for the registers.
3335 (dcache_init): Statically allocate the cache, since it was being
3336 allocated by a malloc that was never freed anyway.
3337 (nindy_create_inferior): Error, not core dump, if no exec file.
3338 (nindy_before_main_loop): Use target_load, not target_add_file.
3340 * remote-vx.c (net_load): Specify large timeout for load
3341 requests. Allow user to break out with INTERRUPT.
3342 (net_break): Remove useless code, clean up. Change callers.
3343 (parse-args, skip_white_space, find_white_space): Clean up arg
3344 parsing to cope with quoted strings.
3345 (net_wait, net_quit): Never call error, just return status.
3346 (vx_read_register, vx_write_register): Cleanup status checking.
3347 #ifdef the code based on which CPU we are using (960 or 68k),
3348 FIXME, this should be completely general but it isn't yet.
3349 (vx_xfer_memory, vx_resume): Cleanup status checking.
3350 (vx_run_files_info): Improve message.
3351 (vx_load_command): Renamed from vx_add_file_command. Allow load
3353 (net_ptrace): Remove unused routine.
3354 (vx_wait): Adopt code from vxgdb960 to cope with broken
3355 connections to target machine and prompt to disconnect. Remove
3356 debug printouts. Map some EVENT_'s to SIGnals.
3357 (add_symbol_stub, vx_open): Print names of object files we found,
3358 and "ok" if we read their symbols OK. Clarify output in general.
3359 (vx_attach, vx_detach, vx_kill): Add these commands.
3360 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3361 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3362 "info files" output, and create_inferior, since we already have
3365 * stack.c (frame_info): Replace Frame_unknown with 0.
3366 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3367 (return_command): Pop until the PC matches as well as the FP,
3368 so it works even if the FP is shared with another function,
3369 as in "frameless" or "leaf" procedures.
3371 * symfile.c (load_command): renamed from add_file_target_command.
3372 (add_syms_addr_command): renamed from add_file_addr_command.
3373 (add_syms_command): Stub to call target_add_syms.
3374 (_initialize_symfile): Change command names and descriptions,
3375 add-file => add-syms, and load from alias to its own command.
3377 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3378 maybe_kill_then_create_inferior): Default for attempts to start
3379 a process, if one is already running, is to ask about killing
3380 it and retry if yes.
3381 (upstack_create_inferior): #if-0 it, strata obsolete it.
3382 (push_target, unpush_target, pop_target): to_close() a target
3383 before unstacking it.
3384 (target_info): Renamed from target_files_info.
3385 (_initialize_targets): Rename "i files" as "i target", accessible
3388 * target.h: Improve comments about the target_ vectored routines.
3390 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3391 Convert commenting style to standard GNU style.
3392 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3393 (SKIP_PROLOGUE): No longer a no-op.
3394 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3395 (*_REGNUM): Sort register numbers.
3396 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3397 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3398 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3399 are now 10 byte extendeds, not 8 byte doubles.
3400 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3401 for nindy versus vxworks targets. FIXME, this should possibly go
3402 in the target vector.
3403 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3404 frame_saved_regs and arg pointer with each frame.
3405 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3406 (FRAME_ARGS_ADDRESS): Use cached result.
3407 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3408 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3409 (PRINT_RAMDON_SIGNAL): Call print_fault.
3410 (POP_FRAME): Now works.
3412 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3413 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3414 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3415 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3418 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3419 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3421 * valarith.c (value_subscripted_rvalue): Avoid handling
3422 floats and doubles specially; it gave alignment errors. Lint.
3424 * valops.c (value_of_variable, value_of_this): Error if unknown
3427 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3428 to avoid alignment problems.
3429 (value_print): Handle unknown value address.
3430 (cplus_val_print): Two args are ignored; remove them. Change caller.
3431 (val_print): Use unpack_long rather than pointer-deref.
3434 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3435 to avoid alignment problems.
3436 (value_being_returned): Error if return value unknown.
3437 (set_return_value): Add bogosity warning, FIXME. *
3439 * TODO: A woman's work is never done.
3441 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3442 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3443 Add ieee-float.o to OBS.
3444 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3445 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3446 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3448 Changes to generalize the VxWorks RPC protocol slightly, to handle
3449 i960 as well as 68000.
3451 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3452 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3453 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3454 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3455 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3456 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3457 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3458 so they will move in target byte order rather than network
3459 byte order (happens to be the same).
3461 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3463 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3465 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3468 Add contribution lines to various files, showing where they
3471 * breakpoint.c (break_insn, check_break_insn_size,
3472 read_memory_nobpt): Remove to mem-break.c.
3474 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3477 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3478 entry has bad register number. This change is not
3479 tested in this release, FIXME.
3481 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3484 * value.h: Force value's contents field to be aligned to hold
3485 at least a double or a long long (if supported). This avoids
3486 doing bcopy's in and out of the contents field.
3488 (step_1): Avoid coredump under obscure circumstances when we
3491 * symtab.h (misc_info): Add field to misc function vector for
3492 any kind of cached information the target code desires. AMD
3493 29000 uses this to avoid repeating examine_function_prologue's.
3495 * coffread.c: Lint. Remove static symfile, read_section_header.
3496 core.c (have_core_file_p): Lint: remove.
3497 expprint.c (print_subexp): Lint.
3498 infptrace.c, valops.c, valprint.c: lint.
3500 Roll in changes from vxgdb-5.0.1:
3502 * symtab.h: Comment byte order of each address class. Add
3503 LOC_LOCAL_ARG for frame-relative args (960).
3504 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3505 symtab.c, symmisc.c: ditto.
3507 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3509 * remote.c (remote_resume): Error if resume with a signal.
3511 * symfile.c (prim_record_misc_function): Clear misc_info.
3512 (fill_in_vptr_fieldno): Check stub type of arg.
3514 * valops.c (value_cast): Avoid looking up names of types whose
3515 name we don't know, to prevent coredump. Sun CC produces typedef
3516 rtx and the name of *rtx is zero...
3518 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3520 Roll in changes from final AMD 29000 port (Tiemann).
3522 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3523 for ../include/a.out.encap.h. This might not work now that BFD
3524 is separately compiled. Instead, BFD support for encap will have
3525 to translate machine type 29k into the right COFF_MAGIC.
3527 * infcmd.c: Remove references to inferior_pid that aren't used
3528 in actual ptrace calls; use target_has_execution, etc.
3529 (have_inferior_p): Remove function.
3530 (program_info): Print target info rather than "process number";
3531 avoid gratuitous messages unless from_tty.
3532 (run_stack_dummy, finish_command): Set proceed_to_finish.
3533 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3534 main.c: Lint. Lose have_inferior_p().
3535 inferior.h (have_inferior_p): Remove, lint.
3536 (proceed_to_finish): Add flag to ask that all regs be saved
3537 by normal_stop, for the few commands that need it, speeding up
3538 serial I/O. Add comments to stop_registers.
3540 * remote-eb.c: Remove newline from breakpoint message we grep
3541 for. Never time out when running the user program.
3545 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3547 Roll in changes from vxgdb-5.0.1:
3549 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3550 symbol in its raw form, we are processing an unlinked ".o" file.
3551 See if the target environment has assigned it an address, using
3552 target_lookup_symbol (VxWorks does), and enter it into the symtab
3555 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3556 68k versions for a simpler version that assumes zero FP at bottom.
3557 Fixes bug of truncated stack reports.
3559 * target.h (target_lookup_symbol): Define this routine's args
3560 and result, finally.
3562 * target.c (nosymbol): Default routine for target_lookup_symbol.
3563 (target_default): Default lookup_symbol and call_function too.
3564 (files_info): Only print has_all_memory warning if a non-dummy
3567 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3568 vx_convert_from_virtual): If target does not have floating point,
3569 zero register "values", and avoid doing cross-net conversions.
3570 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3571 (vx_open): Rearrange code that attaches to target and reads
3572 symbols for all loaded modules, to work if some of the modules
3573 are not accessible. Add symbol_stub() and add_symbol_stub()
3574 as callbacks from catch_errors(). Allow connect attempt to be
3575 interrupted painlessly with ^C (FIXME, there are still some bugs
3576 if the interrupt happens during symbol reading.). Print
3577 final message with puts_filtered, since symbol messages are
3582 * main.c (catch_errors): Only print errstring if non-null.
3583 (command_loop): Avoid an ioctl per command to test ISATTY.
3585 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3586 (vx_xfer_memory): Return correct result!
3587 (vx_files_info): Indicate whether target has float or not.
3588 (vx_lookup_symbol): Complain, not error, if target gone.
3589 (vx_open): Print "Connected" msg before disabling immediate-quit.
3590 [FIXME: lookup_symbol and vx_open changes need testing.]
3592 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3593 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3594 contributor lines and update copyrights to 1991.
3596 Changes from an attempted H-PUX host port:
3598 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3599 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3600 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3601 * remote-vx.c: include <sys/time.h> for HPUX.
3602 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3603 "core_file_command" routine to BFD regime. May not work yet.
3605 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3607 * xgdb.c: Replace X10 version with some VJ version.
3608 (FIXME: Its copyright assignment is not on record.)
3609 * xgdb.c: Update include files to X11R4 (Xaw crud).
3610 (xgdb_display_source, create_text_widget): fix call to
3611 get_filename_and_charpos. Rewack source window stuff for X11R4
3612 (gleaned from include files, and "nm's" of binary libraries, since
3613 I had no doc available).
3614 (append_selection, append_selection_word): Disable with FIXME
3615 since R4 changed interface here.
3616 (create_buttons): Add back the old set of buttons.
3617 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3619 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3620 Roll VERSION to 3.94 (not yet final though).
3622 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3624 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3625 obstack_int_grow, obstack_int_grow_fast): Eliminate
3626 cast on left of assignment, which gives MIPS cc fits and is
3629 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3630 F_ALIAS. Use printf, not fprintf, when not passing a file
3632 (compare_opcodes): Check that identical instructions have
3633 identical opcodes, complain otherwise.
3635 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3636 was reported by Roland McGrath.
3637 (unimp): Only match if exactly zero instruction. (Roland)
3638 (branches and traps): Generate all variations of these
3639 instructions with macros, based on a single call that defines
3640 each condition name and its binary representation.
3641 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3643 * valprint.c (val_print_fields): Take, and use, format parameter.
3644 This means that "p/x struct" again prints the elements in the
3645 desired format. Changed callers.
3647 * stack.c (frame_info): Use filtered output, and indicate wrap
3648 points. Remove kludgy formatting designed to avoid line wrap.
3650 * utils.c (wrap_here): If the line is already full (because
3651 we had printed a long indent or long wrapped string), do an
3652 immediate newline-and-indent.
3654 * m68k-pinsn.c (print_insn_arg): Bugfix from
3655 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3656 instruction is incorrectly disassembled as bkpt #8.
3658 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3659 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3660 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3661 and then will dump core (sometimes). I traced it back to an
3662 uninitialized symfile_name in psymtab_to_symtab.
3663 (const_vol_complaint): Add quotes to message.
3664 (define_symbol): Only believe line number if gcc_compiled.
3665 Avoid allocating symbol if we will not return it.
3667 Add target strata support so that newly established targets go
3668 into their right place in the target stack (e.g. a new exec file
3669 doesn't wipe out the ability to access the running process).
3671 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3672 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3673 and initialize it properly in all the targets.
3675 * target.h: Document strata. Change return type of push_target.
3677 * target.c (nomemory): new function for dummy memory access.
3678 (tcomplain): Rename complain, now also used in symfile.c.
3679 (push_target): Push targets within strata. New return value shows
3680 whether new target is on top of stack or not. Always keep dummy
3682 (target_files_info): Ignore dummy target.
3684 * core.c (core_open): Warn user, and skip accessing file, if the
3685 core target is not the topmost target in the stack.
3686 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3689 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3690 target_ops, it doesn't belong there since we have no regs there.
3691 Change name of target from machine => memory to clarify.
3693 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3695 * Freeze version 3.93 for release.
3697 * Makefile.dist: Handle vx-share and nindy-share subdirs
3698 properly when building gdb.tar.Z.
3700 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3701 printed in various places, so I could change just one copy.
3703 * dbxread.c, coffread.c: Change references to bfd->iostream
3704 to cast to FILE *, now that BFD avoids needing types defined
3705 in other header files.
3707 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3709 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3710 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3711 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3712 (actually gcc -Wall).
3714 * dbxread.c: Remove first_global_sym, last_global_sym, since
3715 they are never referenced.
3717 * defs.h (baud_rate): Declare.
3718 main.c: Define it, and add the -b option to set it.
3720 * gdb-int.texinfo: Add text on how to define a new host or target
3721 architecture, prompted by Per Bothner's questions about MIPS
3724 * gdb.texinfo: Document "complaints". Change doc of -q since
3725 gdb no longer prints the copyright and blurb if you specify a file
3726 name to be debugged (just like Emacs). Add doc for Nindy-specific
3727 command line flags for specifying target serial port and such.
3728 Update copyright to 1991.
3730 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3731 has taken over for us the job of ripping up executable files. The
3732 crud caused Per Bothner's port to not compile.
3734 * infrun.c (normal_stop): Avoid printing "Program exited
3735 normally" if we are in batch mode. This allows a GDB which
3736 executes a program on a target system, to behave like a Unix
3737 command (input from stdin, output to stdout, no extraneous
3740 * main.c (main): Allow additional machine-dependent command line
3741 options to be specified with the ADDITIONAL_OPTIONS,
3742 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3743 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3744 processing to occur just before the main loop with
3745 BEFORE_MAIN_LOOP_HOOK.
3746 (main): If a "core file" argument is specified, and it is not a
3747 core file, try it as a process ID to attach.
3748 (symbol_completion_function): Attempt to cope with
3749 "show screen-" TAB, not very successfully. This needs more work,
3751 (batch_file): New function, returns whether we are reading
3752 commands from an interactive tty on stdin, or from somewhere else.
3753 Called by normal_stop since it doesn't get from_tty passed down
3754 to it like many commands do.
3756 * remote-nindy.c: Handle command line options for nindy
3758 (nindy_before_main_loop): Prompt user for tty name if they
3759 don't specify it before getting to the interactive command loop.
3761 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3762 and -r command line options. Also add hook before main loop
3763 to make it easy to specify a tty.
3765 * TODO: More things to do, one done.
3767 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3769 * dbxread.c: Make complaint() calls pass pointer, not struct.
3770 Add complaints about badly formatted C++ type information
3771 (const/volatile indicator, and parse errors resulting in
3772 error_type). Fix C++ virtual member fn comment.
3773 (read_struct_type): Avoid bumping pointer if we got a parse
3774 error; this prevents our walking beyond the end of a string.
3775 Terminate loop on null char as well as semicolon.
3776 (process_one_symbol): Fix the LBRAC fix so that it uses the
3777 last previous SLINE, FUN, or SO record's PC address. C++ debug
3778 symbols did not have SLINE records in a useful order compared
3779 to the LBRAC records.
3780 (define_symbol): Handle "catch" records.
3782 * symtab.c (check_stub_type): Added new complain
3783 `stub_noname_complain' and added a consistency check to
3784 keep the debugger from crashing when finishing from an
3785 exception frame. A real fix will be needed later.
3787 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3789 * infcmd.c (attach_command): Make global.
3791 * Makefile.dist (REMOTE_OBS): Make these compile by default,
3792 but make them easy to comment out. Perhaps later they should
3793 be enabled by what CPU you configure for? FIXME.
3794 (VERSION): Roll to 3.93.
3795 (pinsn.o): Remove rule for obsolete file.
3796 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
3798 Run down a problem that manifested by printing the wrong function
3799 name in stack traces of read_ofile_symtab. Turned out that the
3800 problem was the SunOS 4.1.1 (and previous) C compiler outputs
3801 the LBRAC symbol with an address in the *data* segment, which
3802 blew our binary search through the blocks.
3804 * dbxread.c: Use the complain() facility consistently to bitch
3805 about problems in the symbol file we are reading.
3806 (finish_block): Add code to check the nesting of the blocks;
3807 complain and Procrust them to fit if wrong.
3808 (make_blockvector): Check the order of the blocks, complain
3809 [but don't cope] if wrong.
3810 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
3811 symbols to be sure their PC value is greater than the last SLINE
3812 (line number) symbol we've seen, complaining and adopting the
3813 SLINE PC value if wrong.
3815 * symfile.h (struct complaint, complaint_root, complain,
3816 clear_complaints): Add.
3817 * symfile.c (complain, complaint_root, clear_complaints): Add
3818 facility to deal with non-fatal complaints and to regularize their
3820 (symbol_file_add): Clear complaint counters to allow new complaints.
3821 (initialize_symfile): Add 'set complaints' and 'show complaints'.
3823 * dbxread.c (dbx_symfile_read): Remember the address and size
3824 of the string table for the main symbol file, so we won't read it
3826 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
3827 to avoid reading the string table yet again. Lint.
3828 (throughout): Improve filtered output, including word wrap.
3829 (read_range_type): Improve Bothner's fix to handle other types too.
3831 * utils.c: Improve line wrap implementation. Handle unlimited
3832 width by making chars_per_line unsigned.
3833 (puts_filtered): New, easy, function.
3835 * defs.h (puts_filtered): add.
3837 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
3838 call the identical sort_symtab_syms() in symfile.c instead.
3840 * expread.y: Suggest the `file' command rather than `symbol-file'.
3842 * command.h (enum var_types): Add zinteger for seroable
3844 * command.c (do_setshow_command): Handle var_zinteger. Restructure
3845 nested if's into a switch.
3847 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
3848 we did not stop because of a breakpoint (it must have been for
3849 some other reason, like a "stepi"), so don't print anything.
3851 * symtab.c: Include <sys/types.h> all the time. Now that BFD
3852 doesn't include <sys/types.h>, old SunOS's require it for
3855 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
3857 A test port of gdb-3.92.6 to the Sony NEWS.
3860 Don't normally link in remote- or vx stuff.
3861 Some of it doesn't compile, and it wastes space for 99% of the users.
3862 Remove reference to no-longer-used HAVE_VPRINTF.
3863 Fixed BFD_DEP typo to BFD_DIR.
3865 Fix cast in arg to bfd_h_getlong.
3866 Make char *prefix be const.
3867 Fix how certain range types are mapped into builtin unsigned int types.
3869 Remove 2 #includes. They cause errors (on Sony, at least),
3870 and aren't needed (they wern't in earlier versions).
3872 print_address_symbolic should never demangle labels
3873 (since it prints *assembler-level* labels).
3875 [This was superseded by the change to printcmd below.]
3878 Add some "volatile" return types to avoid warnings.
3879 If MISSING_VPRINTF add vprintf function and not just macro
3880 (since vprintf is used in printcmd.c).
3882 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
3883 (The latter isn't grokked by some PCC-based compilers.)
3885 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
3887 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
3888 * nindy-share/coffstrip.c
3889 Added some forward declarations (otherwise, gcc complains
3890 about implicit extern redefined as static).
3892 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3894 Changes inspired by Per Bothner:
3895 * printcmd.c (print_address_symbolic): Take additional parameter
3896 specifying whether to demangle.
3897 (print_address): Pass in asm_demangle to control demangling.
3898 (print_address_demangle): New fn, takes explicit arg to control
3900 * utils.c: Add new vars demangle and asm_demangle, and let them
3902 (fputs_demangled): If !demangle, just print the argument.
3903 (fprint_symbol): If !demangle, just print raw symbol.
3904 * valprint.c (val_print): Call print_address_demangle rather than
3905 print_address, to cause demangling to depend on the global
3906 rather than assembler-level demangling setting.
3907 * WHATS.NEW, gdb.texinfo: Document.
3909 * main.c (show_command): Show all settings if no arg.
3910 (initialize_main): Make "info set" the same as naked "show".
3911 * command.c (cmd_show_list): Handle prefix commands in the
3912 list, and print the name of the setting as well as its English
3913 description and value.
3915 Allow gdb functions to specify where a line should wrap if it
3916 exceeds the size of a terminal line. Use it to make the output
3918 * utils.c (set_screen_width_command): New fn, mallocs a buffer
3919 of the right size when screen width changes.
3920 (set_screensize_command, screensize_info): Remove #if 0'd fns.
3921 (wrap_here): New fn, indicates a point in the output where we
3922 should wrap the line rather than just letting it overflow at a
3924 (fputs_filtered): Implement wrapping.
3925 (n_spaces): New fn, returns a pointer to N spaces.
3926 (print_spaces_filtered): Use n_spaces.
3927 * defs.h (n_spaces): Declare.
3928 * stack.c (print_frame_info): Wrap with 4-space indent after
3929 fn name and before filename and line number.
3930 * printcmd.c (print_frame_args): Wrap with 4-space indent
3931 before each argument name is printed.
3932 * valprint.c (value_print): Wrap with no indentation before
3934 (val_print_fields): Wrap with indentation relative to nesting
3935 level before each field name.
3936 (val_print): Wrap with nesting indentation before array elements.
3937 * command.c (do_setshow_command): Avoid extra newlines,
3938 wrap with 4-space indent around values printed, end with period.
3939 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
3941 * breakpoint.c (breakpoint_1): Implement addressprint for
3942 "info breakpoints" display. Change file name and line number
3943 format to " at file:nnn" rather than " (file line nnn)".
3944 * gdb.texinfo: Document.
3947 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3949 Frozen for gdb-3.92.6 release.
3951 README, WHATS.NEW: Update for 3.92.6 release.
3953 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
3954 coffread.o from configs since it is now built by default.
3955 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
3956 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
3957 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
3958 from configs since it is now built by default.
3960 Makefile.dist: Update for release 3.92.6. Handle files that
3961 have been moved to ../include, ../getopt, or ../bfd. Add
3962 saber.suppress and tests directory. Add config.status to
3963 the release (it will say "none").
3965 coredep.c: Minor formatting fixes.
3967 These changes were made in early December but only checked in now:
3968 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
3969 nindy-share/nindy.c: lint
3970 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
3971 register values coming back from the target; we store values
3972 in target byte order everywhere.
3974 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
3976 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
3978 * valprint.c (cplus_val_print, val_print_fields): New functions,
3979 which print C++ objects. They conspire to avoid printing a
3980 virtual base class more than once, following all the twists and
3981 turns of C++ virtual base rules.
3982 (val_print): Call the above rather than do it by hand.
3984 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
3985 symbol file, not for added files like shared libs. This really
3986 needs to be generalized to a timestamp per file.
3988 * core.c (cleanup_core): Avoid coredump if no core file.
3990 * config.gdb: Accept -host or -target in place of +host or
3993 * coffread.c (find_linenos): Avoid desupported BFD interface
3994 to line numbers. We still read them manually rather than using
3995 BFD's "generic" features.
3997 * gdbrc.tex, threecol.tex: Add GDB reference card and its
3999 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4001 * Makefile.dist: Eliminate use of $< in explicit targets.
4003 * readline/Makefile: Use $< rather than $*.c, which does not
4004 include the VPATH in GNU Make.
4006 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4007 copies of tconfig/i960, added for global configuration
4008 compatability. All i960 versions can read both coff and b.out.
4010 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4011 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4014 * TODO: Think of more things to do.
4016 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4018 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4019 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4020 64-bit float conversion.
4022 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4023 equivalent to sun?os4 so global config works.
4025 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4027 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4029 * main.c: Only declare linesize once; declare pagesize not at
4030 all, since it is never used.
4031 (main): Clear newly allocated line before it is used.
4033 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4035 Further stabilization for the Intel 960.
4037 * Makefile.dist: Parameterize the location of the "include"
4038 and "bfd" directories, as well as "getopt". Add symfile.c.
4039 Link in both dbxread and coffread. Fix up "make depend" to
4040 rewack the locations of include, bfd, and getopt in its output.
4042 * README: Document moving include files, improve some of
4045 * coffread.c: Move common code out to symfile.c. Change
4046 symbol_file_command style interface to use new *_symfile_init
4047 and *_symfile_read interface under BFD. Use BFD internal
4048 info to locate line table, symbols, etc.
4050 * core.c (core_fetch_registers): Rename to get_core_registers
4051 to avoid confusion with fetch_core_registers.
4052 (register_addr): Move to coredep.c, which is already machine
4053 dependent. This leaves core.c pretty clean of dependencies.
4055 * coredep.c (register_addr): Accept this routine from core.c.
4057 * dbxread.c: Move common code (with coffread.c, etc) into new
4058 symfile.c. Each psymtab now contains a pointer to the
4059 format-dependent function that knows how to read it in. Make
4061 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4062 (process_one_symbol): Add code to complain about a "compiler bug
4063 we muzzle here", if we actually see it.
4065 * eval.c (evaluate_subexp): Insert missing "break" statements
4066 in code that determines whether a variable is an lvalue in
4067 memory, register, or whatever. I detected this via a compiler
4068 bug in which it *almost* mashed out the whole switch statement.
4070 * gdb-int.texinfo: Add minor sections on configuring gdb for
4071 release, and about the README file.
4073 * infcmd.c (registers_info): Fix formatting somewhat. Still
4074 not as pretty as before, but it handles byte swapping.
4076 * remote-nindy.c: If data cache routines are interrupted while
4077 waiting for the remote end, be sure that any uninitialized cache
4078 blocks are on the free list, not on the valid list!
4080 * symfile.h: Flesh out this header file with all the various
4081 routines and variables that have been merged in from dbxread.c
4082 coffread.c, and symtab.c to symfile.c.
4084 * symfile.c: New file, containing code common to dbxread.c,
4085 coffread.c, and some code from symtab.c. All generic code for
4086 reading symbol files should be in here now.
4087 (unrecord_misc_function): Remove unused function.
4089 * symtab.h: Remove file-reading things to symfile.h.
4091 * symtab.c: Remove file-reading things to symfile.c.
4093 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4094 to decode i960 fault types.
4096 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4097 target.c: Change type of the "resume" function from int to void,
4098 since its result was never used.
4100 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4102 * main.c: Replace "stupid" with "caution"; you now "set caution
4105 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4107 * infcmd.c (do_registers_info): Call val_print to deal with the
4108 byte order of the registers being printed. FIXME, this makes
4109 the formatting of the output uglier.
4111 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4112 defined, call it for signals the debugger doesn't itself use.
4113 The i960 uses this for more detailed fault information.
4115 * remote.c (remote_open): If arg is null, print help rather than
4118 * sparc-xdep.c (register_valid): Avoid declaring size, since
4119 various modules will think of various sizes depending on the
4120 architecture of their tm-file. FIXME, we need protection against
4121 actually entering one of those modules, which would clobber
4122 storage if not for the target architecture compiled into gdb.
4124 * stack.c (up_command, down_command): Always print the frame
4126 (up_silently_command, down_silently_command): New commands
4129 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4131 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4132 more parameters than it used to.
4134 * findvar.c (registers): Increase slop to 256 bytes, which should
4135 protect us against even most RISC machines with large register
4137 (locate_var_value): Move declaration inside related ifdef.
4139 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4140 throughout, to avoid throwing away buffered input from the board.
4141 (nindy_wait): Supply_register takes addr_of_value, not value.
4142 (i960_print_fault): Renamed from i80960_fault.
4143 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4144 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4146 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4147 we can set the PC in the call to proceed(). Unpush nindy_ops
4148 before pushing it on top, to avoid message to user. Eliminate
4149 commentary from Unix machines that just misleads here.
4150 (reset_command): Fix error message to suggest target command.
4152 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4154 Release 3.92.5 as frozen.
4156 Stabilize the merged release...with help from lint, Saber C,
4159 Everywhere: Add include files needed to declare return types
4160 of functions called.
4162 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4164 * breakpoint.h: Add undeclared breakpoint functions, and some
4165 functions for display handling since I couldn't think of a better
4168 * breakpoint.c (insert_breakpoints): Make code for disabling
4169 shared library bkpts more likely to work. It's used when we
4170 rerun a program and stop before the shared library has been
4172 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4173 cast from pointer, so it squeezes through catch_errors.
4174 (bpstat_stop_status): Fix logic broken some time ago. We now
4175 always create a bpstat if the stop address matches a breakpoint,
4176 even if we don't stop there -- just like the old code used to do
4177 before I got my fingers into it (sigh).
4178 (breakpoint_1): Print "ignore count" after "stop only if"
4179 condition, since that's how it actually works.
4180 (mention): Handle watchpoints as well as breakpoints.
4181 (watch_command): use set_raw_breakpoint and mention to do most
4182 of the work (and initialize all the fields!). Only pass one
4183 arg to parse_c_expression, since that's all it takes.
4185 * command.c (not_just_help_class_command): Rename arg to args
4186 since we ignore "unused argument" warnings on vars named "args".
4187 inflow.c (child_terminal_info): ditto.
4188 infptrace.c (kill_inferior): ditto
4189 main.c (catch_errors, version_info, quit_command, pwd_command,
4190 source_command, dump_me_command, editing_info,
4191 set_history_size_command, set_history, show_history,
4193 stack.c (locals_info): ditto
4194 target.c (target_files_info): ditto
4195 valprint.c (set_input_radix, set_output_radix): ditto
4197 * core.c: Remove old variables for handling core and exec file
4198 sections (data_start, data_end, stack_start, stack_end,
4199 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4200 text_end, exec_data_start, exec_data_end, text_offset,
4201 exec_data_offset, data_offset, stack_offset). They're
4202 superseded the more general build_section_table and
4204 (get_exec_file): Mention the `file' command.
4205 (read_memory_check): Rename to memory_error, and only call it
4206 in the case of an actual error.
4207 (read_memory, write_memory): call memory_error.
4208 (core_fetch_registers): Register section name is ".reg".
4210 coredep.c: Remove a bunch of crud now that all this file does
4211 is pull the registers out of a core file.
4212 (fetch_core_registers): Rewrite to actually work, I hope.
4214 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4215 Replace index() with strchr(). Remove all the pre-BFD macro
4216 definitions for accessing the symbol file.
4217 (struct dbx_symfile_info): Encapsulate the information that
4218 dbx_symfile_init needs to pass to dbx_symfile_read in this
4221 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4222 dbx_symfile_discard): Rearrange symbol file reading to divide
4223 the format-specific part from the format-independent part,
4224 leaving the format-independent part such as file name expansion
4225 and opening in symtab.c. This replaces
4226 partial_symbol_file_open and partial_symbol_file_read.
4227 Symbol_file_read, add_file, add_file_target_command,
4228 add_file_addr_command move to symtab.c. Pass an explicit
4229 "mainline" flag for when reading the main symbol table, rather
4230 than relying on the offset address to be zero or nonzero.
4232 (dbx_symfile_read): Don't allow void *'s to be printed as
4234 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4235 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4236 macro" debug version really work.
4237 (read_dbx_symtab): Remove unref'd parameter inclink.
4238 Avoid swapping N_SLINE symbols, for speed.
4239 Merge N_TEXT!N_EXT case with the other external symbol
4240 definitions' case. Add comments.
4241 (start_psymtab): Allocate the symfile name in the psymtab on
4242 the psymbol_obstack, rather than using the caller's storage.
4243 (end_psymtab): Only allocate a dependencies list if there are
4245 (psymtab_to_symtab_2): Use BFD when reopening file to read
4246 its symbols for real.
4247 (read_struct_type): Add FIXME comments where it needs work
4249 (read_huge_number): Add FIXME about overflows.
4250 (read_range_type): Add FIXME about comparing a long to 1<<32.
4252 * coffread.c: Minor changes to move things closer to the new
4253 regime with symtab.c and dbxread.c Major work is still needed
4256 * exec.c (exec_file_command): Remove old variables (see core.c
4258 (xfer_memory): If memory transfer is right at the end of a
4259 section, don't lose.
4261 * findvar.c (get_saved_register): If value is in a real
4262 register, LVAL is lval_register, not lval_memory.
4264 frame.h: Declare print_sel_frame and record_selected_frame.
4266 gdb-int.texinfo: New file, for GDB internals documentation.
4267 Very simple, unformatted doc of cleanups is there for now.
4269 gdbcore.h: Remove obsolete variables that described a.out
4270 section addresses and offsets. (See core.c above.)
4271 Declare fetch_core_registers and registers_fetched.
4273 getopt.c: Declare char *alloca(); even on SPARC.
4275 infcmd.c (run_command): Call target_kill rather than
4277 (step_command, next_command, stepi_command, nexti_command):
4278 Declare from_tty parameter even though we don't use it.
4279 (run_stack_dummy): argument BUFFER is a char array, not
4280 a pointer to REGISTER_TYPE.
4281 (finish_command): using_struct_return needed a value *,
4282 not a struct symbol *.
4284 * infptrace.c (child_xfer_memory): To avoid dependency on
4285 where sections are in memory, try PT_WRITE_D and if that fails,
4286 try PT_WRITE_I. Most Unixes don't care which you use.
4288 * infrun.c (step_resume_break_shadow): Change to array to
4289 match other breakpoint shadow storage.
4290 (clear_proceed_status): Pass address of bpstat to
4291 bpstat_clear, not the bpstat itself.
4292 (child_create_inferior): FIXME comment about if the child
4294 (start_inferior): Remove old function.
4295 (child_open): Use target_kill rather than kill_inferior.
4296 (wait_for_inferior): Ditto.
4297 (insert_step_breakpoint, remote_step_breakpoint): Use
4298 new step_resume_break_shadow.
4300 * inftarg.c (child_wait): If all child processes die,
4301 pretend that the one being waited for exited with signal 42.
4303 * main.c (command_line_input): When scanning for comments,
4304 don't coredump on unclosed quotes.
4305 (quit_command): Use target_kill rther than kill_inferior.
4306 (_initialize_main): Rename class_user from "user" to
4309 * printcmd.c (print_command_1): Initialize "fmt" if no format
4310 is specified by the user.
4311 (print_frame_args): Only add to args_printed if we are
4312 actually fetching args from the stack (avoiding undefined
4314 (_initialize_printcmd): Remove bogus \{ from string.
4316 * remote-eb.c (eb_open): Avoid coredump on no argument.
4318 * remote-nindy.c: Bring out of Intel environment into new
4319 target environment. Remove all conditional compilation on
4320 I80960. Massive hacking throughout.
4321 (nindy_xfer_inferior_memory): New routine stolen from
4323 (nindy_create_inferior): New routine pieced together, probably
4324 not quite working yet.
4325 (nindy_ops): New target_ops struct for nindy.
4327 * remote-vx.c: Use write_memory rather than target_write_memory
4328 to get error checking.
4329 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4331 (vx_create_inferior): Use target_terminal_ours...
4333 * signame.c (_initialize_signame): Always initialize, since
4334 we need the table for things other than psignal.
4336 * solib.c (solib_add): Use symbol_file_add, not add_file.
4337 (solib_address): Return boolean result rather than struct
4338 pointer which nobody else knows the type of.
4340 * sparc-tdep.c, valops.c: Use write_memory rather than
4341 target_write_memory, to get error checking.
4343 * stack.c (locals_info, catch_info, args_info,
4344 get_selected_block, frame_command, up_command): Use
4345 target_has_stack, rather than have_inferior_p or
4348 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4350 * symfile.h: New file, defining the interface between the
4351 generic and object-file-specific symbol reading code.
4353 * symtab.c: Move generic symbol-reading interface to symtab.c,
4354 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4355 table to map BFD targets to symbol-reading modules in GDB.
4356 Change index to strchr.
4357 (lookup_struct_elt_type): Use error() rather than hand-made
4358 simulations thereof.
4359 (lookup_partial_symbol): Speedup slightly when length == 0.
4360 (symbol_file_add): New function.
4361 (symbol_file_command): Call it.
4362 (symfile_open, symfile_init): New function.
4363 (add_file_target_command, add_file_addr_command): moved from
4366 * target.c (target_command): use target_kill.
4368 * target.h (target_files_info): Don't declare, never called
4371 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4372 files to determine stack end address.
4374 * valarith.c (value_x_binop, value_x_unop): Change error message
4375 to be more useful. Pass proper argument to value_struct_elt.
4377 * valops.c (value_assign): FIXME comment that long long
4378 bitfields will break here.
4380 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4381 Update `make saber_gdb' to work better.
4383 * TODO: A woman's work is never done.
4385 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4386 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4387 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4388 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4389 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4390 valops.c, valprint.c, exec.c: Lint.

4395 Continuing Intel 960 port merge of GDB.
4397 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4398 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4399 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4400 Wack over "make depend" so it handles files in subdirectories
4401 vx-share, nindy-share, bfd, and in the current directory.
4403 * blockframe.c (get_prev_frame_info): Remove fatal error
4404 if stack not defined.
4406 * core.c (core_open, core_detach): New functions that handle
4407 the old "core-file" command as "target core" and "detach" instead.
4408 (core_file_command): Call them.
4409 (core_xfer_memory): Use common routine xfer_memory.
4411 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4412 dbxread now uses bfd for everything but symbol reading itself.
4413 BFD internals are used to drag out the relevant file offsets.
4414 (partial_symbol_file_open): Change args all around for BFD.
4416 * symtab.c: Rename "value" to "val" everywhere, so we can
4418 (symbol_file_command): New command, moved from dbxread.c
4419 and coffread.c. It uses BFD to read the file, then vectors
4420 based on its type, to dbx or coff symbol readers.
4421 * symtab.h: Extern a few vars for symbol_file_command.
4423 * target.h: Breakpoint takes a char * save area, not a char **.
4425 * valprint.c (val_print): When unpacking bitfields, offset
4426 the address in gdb of the value, if it is declared with a shorter
4427 type. Remove the last "runtime kludge test" of host byte order.
4429 * utils.c: Remove old my_bfd_read routine.
4431 * stack.c (frame_info): Use target_has_stack. Print program counter
4432 register's actual name rather than "pc", since it's called the
4433 "ip" (instruction pointer) on the i960 (sigh).
4435 * target.c (target_command): Add command for selecting a target
4436 type and calling its open routine. This is used for initiating
4437 communication with a particular target, in a generic way.
4439 * tm-i960.h: Update for modern gdb. Remove semicolons from
4440 various macros. Handle reading struct return convention, and
4441 error-out attempts to return structs with the "return" command.
4442 Be sure gdb doesn't think we know how to call functions in the
4445 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4446 to i960_xxx in lower case.
4447 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4448 not being defined yet.
4450 * remote.c (remote_open): Call start_remote to initialize
4451 wait_for_inferior during open.
4452 (remote_xfer_inferior_memory): Return length written rather
4455 * remote-vx.c (target_command -> vx_open): Use new generic
4457 * remote-eb.c, inftarg.c, exec.c: ditto.
4459 * infrun.c: Fix comments.
4460 (attach_program -> child_open): Use new generic target command.
4461 (wait_for_inferior): Clear saved register values before target_wait,
4462 so target_wait can set some of them if convenient.
4464 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4465 Return success indicator, not void.
4466 (child_xfer_memory): Avoid fetching initial word if we'll
4467 overwrite it anyway.
4469 * infcmd.c (attach_command): Use new generic target open routine.
4470 (_initialize_infcmd): Update doc on attach and detach commands.
4471 (do_registers_info): Merge in a byte-order problem as a FIXME
4474 * findvar.c (find_saved_register): Avoid problem in current frame.
4475 (read_relative_register): Ditto.
4476 (write_register): Convert byte order on the way out.
4478 * exec.c (file_command): Add.
4479 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4480 (xfer_memory): Common function between core_xfer_memory and
4482 (exec_xfer_memory): Use it.
4484 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4486 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4487 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4488 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4490 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4492 Merge Intel 960 port of gdb, continuing...
4494 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4495 symbol_file_command): Pass from_tty arg to hush 'em up.
4497 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4498 Add magic numbers for 960 COFF format.
4500 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4502 Merge Intel 960 port of gdb, from Intel "1.2" release.
4504 CHANGE_LOG entries from their port, which was based on
4507 Thu Sep 6 11:02:22 PDT 1990
4508 Remove temp file if download is interrupted.
4510 Wed Aug 1 09:08:33 PDT 1990
4511 Now uses binary protocol to talk to NINDY.
4512 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
4513 Times out after 5 seconds when trying to talk to NINDY.
4515 Tue May 29 12:54:49 PDT 1990
4516 Added variable baud rate (-b switch).
4517 Source code reorganization.
4519 Thu Apr 26 11:09:55 PDT 1990
4520 More cleanup of batch mode; specifically, execute "-s", "-e", and
4521 "-se" switches as soon as they are encountered on the invocation line.
4523 Fri Apr 20 13:47:15 PDT 1990
4526 Thu Apr 19 09:54:28 PDT 1990
4527 Add 'reset' command.
4529 Wed Apr 18 09:48:07 PDT 1990
4530 After opening remote tty, wait for 1 second to go by without input
4531 from it before trying to talk to NINDY (fixes problems with the
4532 Heurikon HK80/V960E).
4534 Mon Apr 4 16:33:05 PDT 1990
4535 Some output was not being suppressed in 'batch' mode.
4537 Thu Mar 22 15:31:11 PST 1990
4538 Ask user if old symbol table should be deleted when new file is
4541 Allow user to run a program downloaded before gdb960 was brought up.
4543 Correct "exec-file" help message for i80960 context.
4545 Correct bug in calculating user space address: could occasionally
4546 corrupt user program.
4548 Make sure to zero low-order bits in rip's because of bug in 960CA
4549 A-step part: could cause operation faults when "next"ing across
4552 Correct bug that made it impossible to get source line numbers for
4553 code loaded at addresses higher than 0x7fffffff.
4555 Wed Jan 10 12:43:22 PST 1990
4556 Open remote tty for exclusive use.
4558 Fri Jan 5 12:14:42 PST 1990
4559 Correct disassembly (CA manual was right after all):
4560 opcode for sysctl is 0x659
4562 Mon Oct 23 12:03:04 PDT 1989
4563 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4565 Mon Oct 16 14:15:09 PDT 1989
4566 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4568 Mon Oct 2 15:56:31 PDT 1989
4570 Added 960CA disassembly support.
4572 To simplify maintenance:
4573 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4575 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4576 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4577 - made disassembly interface identical to that in gdmp960.
4581 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4583 * target.h: Allow targets to stack. Add target_has_memory,
4584 _registers, etc. Restructure memory access and "info files"
4585 to walk the target stack.
4586 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4587 target.c: Change tables to match target.h.
4588 * inflow.c (child_mourn_inferior): pop child_ops.
4589 (generic_mourn_inferior): Use new has_stack flag.
4590 * infptrace.c (child_xfer_memory): New memory regime.
4591 * inftarg.c (child_files_info): New "info files" regime.
4592 * remote-eb.c: New memory regime, new info files.
4593 * remote-vx.c: New memory regime, new info files. Now use
4594 separate targets for VxWorks attachment to machine, and
4595 actually running a process under VxWorks, since one has
4596 stack & execution & regs and the other doesn't.
4597 * remote.c: New memory regime, new info files.
4598 * sparc-xdep.c (fetch_core-registers): New memory regime.
4599 * target.c: New routines and support for stacked targets,
4600 new memory regime, new info files regime.
4603 Generalize section handling for an arbitrary number of sections,
4604 including use of the new BFD (binary file) library.
4605 * gdbcore.h: Add struct section_table.
4606 * exec.c (build_section_table): Iterate all sections and
4607 record what gdb needs to know about them.
4608 (exec_command): Use it.
4609 (exec_xfer_memory): Use the table.
4610 (exec_files_info): Print the table.
4611 * core.c (core_file_command, core_xfer_memory, core_files_info):
4613 * source.c (find_source_lines): Use bfd_get_mtime.
4614 * dbxread.c: Quick changes to make it compile with new BFD.
4615 * utils.c (error): Avoid using bfd_error in generic routines.
4617 * core.c (core_fetch_registers): Get from the ".regs" section of
4619 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4621 * inferior.h (attach_flag): Export.
4622 * infcmd.c (run_command): use new target_create_inferior.
4623 * infrun.c (child_create_inferior): Don't return result.
4624 * Makefile.dist (VERSION): 3.91.4.
4626 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
4628 * breakpoint.c (bpstat_num): Handle breakpoints which have
4629 since been deleted, such as temporary breakpoints.
4630 infcmd.c (program_info): ditto.
4632 * core.c (core_file_command): Display the frame where the core
4637 * remote-vx.c (target_command): Merge in target command from
4638 targ-vx.c. A few other cleanups.
4640 * TODO, Projects: Lots more stuff to do...
4642 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4644 Massive changes to wall off the remote-debugging interface
4645 behind a function vector. The port to handle VxWorks targets
4646 is also part of this.
4648 All files: Replace references to renamed functions,
4649 remove references to remote_debugging, remove references to
4650 have_include_file, have_core_file in favor of target_has_stack,
4651 target_has_memory, etc.
4653 * Modularize the breakpoint interface.
4654 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4655 a breakpoint instruction.
4656 breakpoint.c: struct breakpoint's shadow_contents now sized as
4658 (insert_breakpoints): Vector to target to install breakpoints.
4659 (remove_breakpoints): Vector to target here too.
4660 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4661 sparc-tdep.c (single_step): Use new breakpoint interface for
4662 the single-step breakpoints.
4663 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4664 New file, contains routines to insert and remove breakpoints by
4665 reading out the old contents and later replacing them. This is
4666 how ptrace breakpoints work, and many remote systems as well.
4668 * tm-vxworks68.h: New config file, overrides a few things for
4669 Wind River's preferences.
4671 * target.h: New file, for transfer vector used to talk to the
4672 inferior (child, attached, core, exec, remote, etc). All accesses
4673 to the thing being debugged should come through these vectors.
4674 target.c: New file, routines to handle transfer vector.
4675 (various files): Add transfer vectors XXX_ops for the various
4676 targets and pseudo-targets (core files, etc) we support.
4678 * breakpoint.c (bpstat_stop_status): Further explorations of
4679 watchpoints and why things don't work all the time.
4680 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4682 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4683 the local gdbinit if it doesn't already have it.
4685 * core.c (core_ops): add and install.
4686 Allow core debugging without exec file.
4688 * dbxread.c (free_and_init_header_files): Merge two fns.
4689 (end_symtab): Free named symbol table when a new version comes in.
4690 (read_dbx_symtab): Relocate all kinds of symbols with base
4691 address. First step toward handling different text, data, bss
4693 (add_file_addr_command): Renamed add_file_command.
4694 (add_file_command): Vector to remote handler.
4695 Add "load" as an alias for "add-file" command.
4697 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4698 non-returning functions.
4700 * exec.c: Add exec_ops, and push it as a target when an exec
4703 * infcmd.c (run_command): Pass executable file name and arg list
4704 separately when starting an inferior. Permit "run" when no exec
4705 file is specified, for VxWorks.
4706 (detach_command): Move to child_detach in inftarg.c.
4708 * inftarg.c: New file. Unix-child-specific routines, and the
4709 child_ops structure.
4711 * inferior.h (registers): Export "registers" as the way for
4712 target dependent register handlers to find gdb's local copy of
4713 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4714 since it is now used by places that want wait_for_inferior to
4715 handle the grunge but want to see every trap from the inferior.
4717 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4718 Eliminate remote_debugging hooks in terminal handling.
4720 * infrun.c: Replace start_inferior with child_create_inferior.
4721 Move all the hair of Unix shells and ptrace idiosyncracies into
4722 child_create_inferior, so remote handlers don't have to deal.
4723 Remove running_in_shell. Rename stop_after_attach to
4724 stop_soon_quietly, and use it in a few other places where we want
4725 to just call wait_for_inferior and get control back on the first
4726 trap. trap_expected now never takes a value > 1.
4727 (init_wait_for_inferior): Initialize static vars when a new
4730 main.c (gdbinit): Add new hook for .gdbinit file name, let
4731 it be overridden by config files as GDBINIT_FILENAME.
4732 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4733 Both of these are used for VxWorks gdb.
4735 mcheck.c: rename include file "gmalloc.c" to avoid problems
4736 with system include file "malloc.c".
4738 param-no-tm.h: New include file, same as param.h but does not
4739 include the default "tm.h" file. This is used in files where
4740 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4742 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4744 remote-vx.c: New file, VxWorks remote debugging support. Uses
4745 RPC routines that are shared with the target system, in directory
4748 remote.c: Vectorize remote interface.
4750 source.c: Globalize source_path, and make an alias "l" for "list"
4751 since we now have the "load" command.
4753 sparc-xdep.c: Use new param-no-tm.h.
4755 symmisc.c (free_named_symtab): Add new function from Wind River.
4756 However, ifdef it out for now while we think about what it should
4759 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4761 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4762 non-Unix-children handle this with their own code in the target
4765 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4766 source and target lists. Add vx-share to default list of include
4767 directories. Add new files to src and target lists: mem-break,
4768 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4769 ${srcdir} versions of munch and createtags are used.
4771 * valops.c (find_function_addr): Split out of call_function.
4772 (call_function_by_hand): Rename call_function; this function
4773 calls functions in the target by laboriously patching the target
4774 word-by-word with the right stack, args, regs, etc.
4777 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
4779 Handle AMD 29000 a bit better.
4781 * remote-eb.c (readchar): Mask received char log to make it readable.
4782 (remote_start): Pass arguments down to executing program.
4783 Make startaddr unsigned.
4784 infrun.c (start_inferior): Accept args, pass them to
4786 infcmd.c (run_command): Pass args down to start_inferior.
4788 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
4789 the target object file format.
4790 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
4792 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
4793 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
4795 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
4797 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
4798 * TODO: We did a few things, we have more to do though.
4800 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
4801 * inflow.c (inferior_died): Clear deferred stores.
4803 * Debug problems with dummy frames and calls to the inferior.
4804 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
4805 * sparc-tdep.c (do_restore_insn): Simplify.
4806 (sparc_frame_find_saved_regs): Simplify and fix what we find.
4807 (sparc_push_dummy_frame): Simplify and fix what we push.
4808 (sparc_pop_frame): Slightly more hair here, deciding whether
4809 we are restoring a saved PC or returning to a return address in %i7.
4810 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
4812 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
4813 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
4814 * obstack.h (chunkfun): ditto.
4815 * defs.h (xmalloc, xrealloc): ditto
4817 * utils.c (quit): Grab the terminal from the child if necessary.
4819 * inflow.c (term_status_command): Rename to term_info, change
4822 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
4823 (is_delayed_branch): Speed up.
4824 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
4825 Still missing some float ops, and needs testing.
4827 * Support for input and output radixes other than base 10
4828 * defs.h (input_radix, output_radix): Declare.
4829 * expread.y (yyparse, parse_number): Handle changes of input
4830 radix, and ambiguous names-or-numbers in radixes >10.
4831 * printcmd.c (print_scalar_formatted): Print formatted hex
4832 numbers in varying column widths.
4833 * valprint.c (val_print): Use output_format to print scalar ints.
4834 (set_input_radix, set_output_radix, set_radix): Create.
4835 (set_output_radix): Set output_format from output_radix.
4836 (_initialize_valprint): add `set radix' but leave the others off.
4838 * main.c (execute_command): Let stupid questions be turned off.
4839 (_initialize_main): Handle "set stupidity", etc.
4841 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
4842 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
4844 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
4846 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
4847 bfd stuff is still screwed up, but with some manual work, it
4850 * breakpoint.c (bpstat_do_actions): Start over if a command
4851 proceeds the inferior, since the inferior will have stopped and
4852 will need to have its new stop-actions taken care of.
4854 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
4855 compiler fits, simplify it.
4857 * gdb.texinfo (directory command): Doc new dir command.
4858 source.c (directory_command): "dir" now puts things on the front
4859 of the path, moves dups up front, and handles multiple names
4860 on the command line, inserting each one in order. It also
4861 blows away cached line and full_filename info.
4863 * stack.c (backtrace_command): Skip "more stack frames follow"
4866 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
4867 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
4868 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
4869 The only odd one was Gould NP1, which had defined vprintf to
4872 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
4873 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
4874 variable, inspect_it.
4875 valprint.c (print_string, val_print): Use the global inspect_it
4876 to indicate whether to print in Epoch style or normal style.
4878 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
4880 * printcmd.c (call_command): add an alias for the "print" command
4881 which runs expressions and doesn't print the result if void.
4882 (print_command_1): implement it.
4884 * command.c: Remove #if 0'd code. Initialize all the fields
4885 in add_cmd (). Rename do_nothing_command to
4886 not_just_help_class_command, and make it externally visible.
4887 command.h: add user_commands to struct.
4888 * main.c (define_command): Don't overload c->function with a char
4889 string as well as a function pointer.
4891 * eval.c (evaluate_subexp): Reinstall tiemann changes to
4892 calling convention of value_struct_elt () that got dropped in
4895 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.

4898 * tm-sparc.h (POP_FRAME): replace some constants with defines.
4900 * sparc-xdep.c (store_inferior_registers): defer stores to regs
4901 until a good time (e.g. when we are about to run the child),
4902 saving ptrace calls.
4903 * infrun.c (proceed): handle DO_DEFERRED_STORES.
4904 * tm-sparc.h: define DO_DEFERRED_STORES.
4906 * sparc-xdep.c (store_inferior_registers): when storing float
4907 registers, don't store stack regs too. When storing the SP,
4908 however, DO store the stack regs too. This fixes a bug in which
4909 the dummy frame is not recognized when a call_function finishes,
4910 because its frame pointer (in the stack regs) was never
4912 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
4913 even though we don't know how to read them from an inferior.
4914 valops.c (call_function): Comment about storing SP.
4916 * infrun.c (save_inferior_status): Save away the original bpstat
4917 chain so it can be restored later. Install the copied version for
4918 use by whoever saved the status. It will be blow away by
4919 restore_inferior_status, and the original chain restored. This is
4920 important for people who have pointers into the original.
4922 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
4923 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
4924 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
4927 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
4929 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
4930 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
4931 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
4933 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
4935 * Merge Mike Tiemann's multiple inheritance changes from Sun.
4936 Store the baseclasses in a type struct starting from array element
4937 0 rather than from the unusual array element 1.
4939 dbxread.c: the above.
4940 (virtual_context): Add
4941 Read new debug information about which virtual function table
4942 a virtual function is from, and store it in fn_field.fcontext.
4944 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
4945 TYPE_FN_FIELD_STATIC_P.
4947 symtab.c: the above.
4948 valops.c: the above. Handle pointer casts of object *'s.
4949 (search_struct_method): Add.
4950 (value_struct_elt): First arg is now a pointer to a value, and is
4953 valprint.c: the above.
4954 values.c (value_virtual_fn_field): Add type arg. Handle
4955 offsetting to the proper object when calling virtual fns.
4957 (baseclass_addr): Add valuep arg.
4959 * README: Document the current state of BFD config (missing).
4960 * TODO, ChangeLog, Makefile.dist: Roll version.
4961 * WHATS.NEW: Add summary of changes since 3.5.
4963 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
4965 * dbxread.c (read_struct_type): Clear bit vectors whenever
4967 symtab.c (B_CLRALL): define.
4969 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
4970 using == rather than =. Huh... This fixes the dreaded problem
4971 wherein builtin_type_int becomes TYPE_CODE_FLT.
4973 * core.c (info_files): Show the inferior pid.
4975 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
4976 already knows how to look in the source directory.
4978 * Remove psymtab hair from many places. Remove duplicated code
4979 for searching symbol tables. Hide psymtabs from most places.
4980 Make it fast to get from a psymtab to its symtab.
4982 blockframe.c (blockvector_for_pc): Remove psymtab hair.
4983 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4984 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4985 dbxread.c: export psymtab_to_symtab, make it work if called N times.
4986 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
4987 new symtab completely. New psymtabs get symtab pointer
4988 initialized to zero. Remove MI warning printf.
4989 symtab.h: Comments. Add psymtab to symtab pointer.
4990 (PSYMTAB_TO_SYMTAB): New macro.
4991 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
4992 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
4994 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
4996 (print_frame_info): Avoid special-casing symbols that have not yet
4999 * source.c (open_source_file): Quick path if we have already
5000 located the source file by its full name.
5002 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5003 find_pc_psymtab. When a name is found in the misc function
5004 vector, search the symbol table for its mangled name, not the
5005 name that the user typed.
5007 * bfd.h: Fix missing comment terminators, make #endifs match.
5009 * valarith.c (value_less): Handle unsigned int comparisons.
5010 Add FIXME about pointer compares, which assume host and target
5011 pointers are the same.
5013 * command.c (do_nothing_command): lint
5014 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5015 fix comments on debug symbol format for visibility. Actually set
5016 visibility of symbols.
5017 main.c (echo_command): lint; use <readline/history.h>.
5018 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5019 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5020 pointing past end of allocated memory; saber complains.
5021 obstack.h: Declare the external functions that we use.
5022 valarith.h: use <string.h>
5023 solib.c (solib_add): lint.
5025 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5027 * main.c (initialize_main): Default info_verbose to off, now that
5028 symbol reading is fast.
5029 (quit_command): Avoid clobbering exec_bfd while quitting.
5031 * Initial BFD (binary file diddling library) merger:
5032 coffread.c: Change AOUTHDR to struct exe_hdr.
5034 core.c: initialize initialized data at compile time.
5035 (core_file_command): Move from coredep.c, convert to bfd.
5036 (xfer_core_file): Convert to bfd.
5037 exec.c (exec_file_command): use bfd routines.
5039 mips-tdep.c: Remove exec_file_command and friends.
5042 * coredep.c: (fetch_core_registers) Convert core_file_command to
5043 fetch_core_registers.
5044 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5046 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5047 (my_bfd_read): More bogosity, which I don't think we call.
5048 (program_name): Remove this atrocity asap!
5050 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5053 values.c: allocate_repeat_value was not clearing the
5054 optimized_out field.
5055 (value_static_field): minor stylistic fix (wrong macro was used).
5056 valops.c (value_struct_elt_for_address): didn't work for C++
5059 * signame.c (_initialize_signame): Initialize signal names once.
5061 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5062 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5063 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5065 * remote-eb.c: Support user-settable baud rates on the serial port.
5067 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5069 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5071 * tconfig/sun3os4: Remove warning about native assembler,
5072 since it also occurs in the xconfig file.
5074 * findvar.c (registers): Allocate some slop after `registers'
5075 to prevent stray accesses from trashing the next variable.
5077 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5078 on the sun-3, by changing the #ifdef from `sun3' (which is not
5079 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5080 vars, which happened to follow `registers' in the executable.
5082 * readline/history.c (history_search): Heed gcc-2's advice
5083 and parenthesize && inside ||).
5085 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5086 tm-29k.c: Insert FSF copyright headers.
5088 * remote-eb.c: Better comments.
5090 * Makefile.dist: Update to 3.91.6.
5091 * TODO: note PREPARE_TO_STORE problem.
5093 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5095 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5097 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5099 * infrun.c (wait_for_inferior, at end): Don't set up
5100 prev_* if the inferior no longer exists.
5102 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5103 CANNOT_EXECUTE_STACK.
5104 valops.c (call_function): Use it.
5106 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5108 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5109 infrun.c (wait_for_inferior, 2 places): Use it.
5111 * values.c (value_being_returned): Only use
5112 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5114 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5115 right thing for remote-eb.c.
5117 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5118 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5120 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5121 (FRAME_FIND_SAVED_REGS).
5123 * findvar.c ({fetch,store}_registers): Check for
5124 REMOTE_{FETCH_STORE}_REGISTER macro.
5126 * findvar.c (get_saved_register): Add argument lval and
5127 change meaning of argument addr.
5128 findvar.c: Change calls to get_saved_register to reflect
5129 new calling convention.
5130 valops.c (value_assign): Use get_saved_register instead of
5131 find_saved_register.
5133 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5135 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5136 an (uninitialized) pointer to one. Use "&" when passing it
5139 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5141 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5144 * coffread.c (symbol_file_command): Put semicolon after
5146 Put safe_to_init_tdesc_context in #if defined (TDESC).
5147 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5148 coffread.c: #include <sys/stat.h>.
5149 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5150 Add missing ')' in check for "lc%" and friends. Remove
5152 Declare read_one_sym() at top of file.
5153 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5154 MC68WRMAGIC can have the same value without causing a duplicate
5157 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5159 * Allow a Makefile to be built without building the
5160 tm and xm file links that screw up builds in subdirectories.
5161 This is done with `config.gdb none', then you can do things
5162 like `make gdb.tar.Z'.
5163 * tconfig/none: Config file for no target system
5164 * xconfig/none: Config file for no host system
5165 * config.gdb: If no TM or XM files are called out by the
5166 host or target file, don't make links for them.
5168 * cplus-dem.c: Add documentation.
5170 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5171 simple error, so the user's gdb doesn't crash due to some object
5172 file problem (e.g. somebody is rebuilding the file out from under
5175 * printcmd.c (print_address_symbolic): demangle the symbol.
5177 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5178 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5179 (alldeps.mak): sort and uniq all results from this; duplicates
5180 hose gdb.tar.Z link building. Remove RCS files from
5181 tconfig and xconfig. Add config files for sun386. Add
5182 a few odd files to OTHERS and HFILES.
5184 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5186 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5187 Roll version number to 3.91.5. Make lint work in bindir.
5189 * README: Document cross-debugging and new file structure.
5191 * blockframe.c: Lint. Include "value.h" to declare read_register.
5192 (find_pc_partial_function): remove duplicate line.
5194 * command.h: Lint. Declare error_no_arg and dont_repeat.
5196 * tm-news.h: Remove inadvertently duplicated stuff.
5198 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5199 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5201 * config.gdb: Allow `config.gdb host target' form. Clean
5202 up previous change that printed bogus messages when you just said
5205 * core.c: #include "command.h" for lint.
5208 * main.c: Remove some casts of enums. Lint.
5215 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5217 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5218 read it from memory. This will allow us to save ptrace calls
5219 eventually. Changed caller single_step too.
5221 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5222 that we aren't going to use, saving many ptrace calls, especially
5223 when watchpointing or single stepping. Use some #define's for
5225 (store_inferior_registers): Ditto.
5226 (core_file_command): Use some #define's for constants.
5228 * tm-sparc.h: Add #define's for some register numbers, so we
5229 can eliminate the use of random constants in sparc-xdep.c.
5231 * stack.c (frame_command, print_frame_info, up_command,
5232 down_command) Remove frame_changed, since it
5233 causes a bug and doesn't seem to do anything useful. In some
5234 places it was used as a flag, in others as a stack level (?).
5236 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5237 default is to use the portable (vprintf) version rather than the
5239 * xm-news.h (MISSING_VPRINTF): Add.
5241 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5243 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5245 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5246 about linking debugged programs -Bstatic in the sun?os4 config
5247 files in tconfig and xconfig subdirectories.
5249 * main.c (main): Remove unreached exit(0) now that we exit
5252 * Create TODO file for online bug list. There are too many
5253 "little" bugs to keep track of on paper.
5255 * Change Projects file to refer to bug-gdb@cygnus.com
5256 rather than kingdon@ai.
5258 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5260 * Makefile.dist (VERSION): 3.91.4 now.
5262 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5263 (condense_misc_bunches): Add sanity check that misc_count is
5264 the same as the number of symbols in the bunch.
5266 * coffread.c: rename init_misc_bunches. Pass an argument
5267 to condense_misc_bunches (a zero).
5269 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5270 every time we are called; don't rely on our caller to do it.
5271 (add_file): Remove call to init_misc_bunches.
5273 * mipsread.c: Only warn, don't error, if unknown symbol types.
5274 This keeps an old gdb from falling on its face if it sees newly
5275 extended symbol info. Rename init_misc_bunches.
5277 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5279 * Merge in changes from Per Bothner for DECstations and other
5280 MIPS stuff. The rest is Bothner speaking:
5282 The next message is a merger of Alessando Forin's mips port with
5283 mine. I've tried to use my good if biased judgment to get
5284 the best of both. It *does* need testing.
5286 Some of the changes are general, *not* mips-specific.
5289 Didn't believe in little-endian bit order.
5290 There are still inconsistencies about whether flags
5291 like BITS_BIG_ENDIAN are integer (#if ...) or
5292 boolean (#ifdef ...). I tried to paper over them.
5294 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5295 Moved some misc_function code that was common to
5296 {dbx,coff,mips}read.c to symtab.c.
5297 In the process, I think I cleaned things up a bit.
5298 At the same time, moved obsavestring and obconcat to symtab.c.
5301 Removed obsolete condense_addl_misc_bunches (use
5302 condense_misc_bunches(1) instead).
5305 Needed to include <sys/dir>, at least on DECstations.
5307 valops.c, mips-tdep.c, tm-mips.h:
5308 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5309 conventions (when STACK_ALIGN is insufficient).
5310 Needed on mips, where doubles need 8-byte alignment,
5311 but ints only need 4.
5314 Removed cruft that was not being used.
5315 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5318 Print $ before register-names (I think that makes things a little
5320 Never print two instructions, even if one delays.
5321 Removed hex-disassemble set_cmd. (This is not mips-specific,
5322 so I think the argument is whether it is generally worthwhile or not.
5323 I'm inclined to think not, given how easy it is to
5324 convert between radixes in gdb.)
5327 This is basically Alessando's code.
5328 It doesn't use obstacks; I changed it to use obstacks
5329 in a few minor places where using malloc causes a
5330 memory leak. (Probably, more places could/should be changed.)
5331 I added record_misc_function where it was missing.
5332 In symbol_file_command and add_file_command, I tried
5333 to make the code consistent with more recent versions.
5334 Minor sylistic changes in parse_procedure.
5335 Make a .gdbinfo. psuedo-symbol point back to the real
5336 procedure symbol (using the isym field).
5339 This is basically from my port, but with a lot of details
5340 and a number of routines merged in from Alessando's version.
5341 I basically used my code "raw" backtrace (use heuristics
5342 from the actual code, rather than symbol table info) - though
5343 the idea is Alessandro's. I feel my code is a little cleaner
5344 here, particularly in being a little more flexible, such as being
5345 able to handle gcc-produced code (which it now can).
5346 It also doesn't do frame caching (which is not useful
5347 more recent gdb versions).
5348 I also used my code for push_/pop_dummy, more or less.
5349 I tried to incorporate AF's code for testing sigtramp
5350 while backtracing; I probably got it wrong.
5351 Added mips_print_register, which tries to scrunch as much
5352 information as possible on a screen...
5353 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5354 under mips-pinsn.c), I don't see anything mips-specific here,
5355 and I don't see it being all that useful anyway.
5358 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5359 Use more register names (rather than hard-cases numbers).
5361 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5363 * Hack up 3.90.11 changes:
5365 * Makefile.dist (depend): parameterize $(GCC).
5366 Add solib.c and solib.o.
5367 (readline): Fix vpath for both absolute or relative SRCDIR.
5369 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5370 Also, let the part I didn't understand at least compile so
5371 I can test the rest. FIXME.
5373 * dbxread.c: Fix thinko using strcmp.
5374 (init_psymbol_list): declare static.
5375 (partial_symbol_file_open): Comment cleanups better, avoid
5376 cleaning up the string table since the caller will do that.
5377 Move the stat for mod time into symbol_file_command, temporarily.
5378 (There should be a mod time for each symbol file, eventually,
5379 to control its rereading. FIXME.)
5381 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5382 SunOS, which gives error for shared libs otherwise. (From
5383 Schaefer, probably FIXME needs work for portability.)
5385 * solib.c: Move #include "param.h" to work.
5386 Lowercase all the Uppercase Letters In the Messages.
5387 (find_solib): Clean up inferior_so_name for debug printouts.
5388 Allow no argument, to mean all shared libraries.
5390 * symmisc.c: include param.h to get CLEAR_SOLIB.
5392 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5394 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5395 to 3.90.11. ChangeLog entries below are from this.
5397 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)

5409 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5411 * sparc-opcode.h Added single-operand version of rett.
5413 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5415 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5416 Put parens around gcc_p in expansion.
5418 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5420 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5422 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5424 * Changes for Sun shared libraries:
5425 blockframe.c (find_pc_partial_function): If a non-text symbol
5426 is found, set *address = pc - FUNCTION_START_OFFSET.
5427 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5428 Disable breakpoints instead of giving an error.
5429 source.c (select_source_symtab): Initialize cs_pst.
5430 symmisc.c: Call CLEAR_SOLIB if defined.
5431 symtab.h: Make text{low,high} CORE_ADDR not int.
5432 (psymtab): New field addr.
5434 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5435 (record_misc_function): Give correct type for N_DATA symbols.
5436 (condense_misc_bunches): do "misc_function_count = j" regardless
5438 Take code which is shared between symbol_file_command and
5439 add_file_command and put it into partial_symbol_file_{open,read}.
5440 Split add_file_command into add_file_command and add_file.
5441 Make psymtab_to_symtab read in the string table if the file
5443 Two new parameters to read_dbx_symtab and start_psymtab.
5444 tm-sunos.h: New file.
5446 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5448 * infcmd.c: Change cont_command to continue_command and "cont"
5451 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5453 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5455 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5457 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5458 size 1,2,4,8 rather than size < 8.
5460 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5461 as necessary, not just once.
5463 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5465 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5467 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5469 * tm-news.h: Add CALL_DUMMY_*.
5471 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5473 * config.gdb: In list_host, list_target, use ${i}, not $i.
5475 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5477 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5479 * sparc-opcode.h: Change all store floating-point state register
5480 instructions to have the right match & lose fields.
5482 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5484 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5486 config.gdb: If srcdir != ., create readline directory and
5487 copy a makefile into it.
5489 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5490 consistency with POSIX.
5492 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5493 when we exit its exp_valid_block.
5495 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5497 * Makefile.dist: Bump version to 3.91.3.
5499 * Clean up handling of breakpoint commands (somewhat).
5500 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5502 inferior.h: Add breakpoint_proceeded to inferior status struct
5503 and globals; save it and restore it.
5504 (clear_breakpoint_commands): Cleanup, remove old #define.
5506 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5507 (save_inferior_status, restore_inferior_status): handle it also.
5508 (proceed): Remove earlier code that set breakpoint_proceeded.
5509 It is now set only in clear_proceed_status.
5510 (clear_proceed_status): Cleanup, use bpstat_clear rather
5511 than clear_breakpoint_commands. No callers need the stop_bpstat
5512 between clear_proceed_status and proceed.
5514 infcmd.c: Add breakpoint_proceeded definition and comment.
5515 (cont_command, jump_command, signal_command): Move call to
5516 clear_proceed_status right next to call to proceed.
5518 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5519 caller's argument while running down the chain of breakpoints.
5520 Use new variable "breakpoint_proceeded" to determine when
5521 a command that it executes moves the inferior past the
5523 (bpstat_clear): Handle NULL argument.
5524 (bpstat_clear_actions): Avoid useless call to
5525 breakpoint_auto_delete.
5526 (delete_breakpoint): Clean up bpstat's that are pointing to
5527 the deleted breakpoint from the stop_bpstat chain.
5528 (breakpoint_auto_delete): Simplify.
5530 * Clean up handling of EOF, error on stdin, etc. This was
5531 prompted by a network problem that caused gdb to go into an
5532 infinite loop filling up its malloc'd memory.
5534 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5535 not clear_breakpoints_commands, which is now gone.
5536 (main): If command_loop returns (e.g. from EOF on stdin), do
5537 a quit_command (looping back to command_loop if quit_command
5538 doesn't really quit).
5539 (command_loop): check result from command_line_input and
5540 exit if it returns NULL, rather than passing the NULL to
5542 (gdb_readline): Free malloc'd result space before returning
5545 * utils.c (query): Handle C-d to mean "yes", just as if the
5546 input was not a terminal. Also avoid infinite loop if EOF
5547 occurs in mid-input-line before newline. This allows
5548 query to be used at EOF on stdin with reasonable results.
5550 * infrun.c (proceed): Set breakpoint_proceeded.
5552 * values.c (value_as_long): Avoid infinite recursion for enums.
5553 (_initialize_values): Fix typo in help msg (kingdon).
5555 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5556 RL_LIB for linking. This allows -lreadline for linking
5557 and nothing for dependencies, once readline is a real library.
5559 * config.gdb: Jim Kingdon: give useful error message if the
5560 host or target type is not recognized.
5562 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5563 it just defines it. Dumb, but deal with it.
5565 * Jim Kingdon suggests:
5566 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5568 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5570 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5572 * Clean up Bothner's changes.
5574 * blockframe.c (clear_pc_function_cache): New function.
5575 * blockframe.c: remake cache_pc_function_* static.
5576 * dbxread.c (symbol_file_command): remove references to
5577 cache_pc_function_* variables.
5578 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5579 * printcmd.c: Avoid kludging a global variable (addressprint)
5580 to avoid printing the address of a string twice. Instead,
5581 pass the format letter 's' down low enough that it can be seen
5582 to avoid this problem.
5583 (print_formatted): Pass format arg to value_print.
5584 (restore_addressprint): Remove function.
5585 (do_examine): Avoid hacking addressprint, cleanups and such.
5586 (print_frame_args): Add a comment to a Bothner change.
5587 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5588 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5589 to wipe out the values cached in blockframe.c.
5590 * symtab.c (find_method): Add comment saying how big you must
5591 allocate to be "big enough". Per being terse again.
5592 * valprint.c (val_print): Handle format letter "s" to print
5593 strings without addresses. Add comment to vtbl printing code
5594 which casts with wild abandon. Rearrange reference-printing
5596 @0xaddr: value (print w/addressprint)
5597 value (print w/~addressprint)
5598 @0xaddr (parameter lists w/addressprint)
5599 or nothing (parameter lists w/o addressprint)
5601 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5603 * Merge more changes from Per Bothner:
5605 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5606 annoying) that I tried to improve it. Here are my suggestions.
5608 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5611 Do automatic de-reference when taking the address of a reference.
5613 Don't deref_ref when printing parameter lists.
5615 More attempts at treating refernences properly.
5617 In val_print, if deref_ref==0, don't print dangling " = ".
5619 Add COERCE_REF macro, which de-references an REF.
5621 * Merge changes from Per Bothner:
5623 * Fixed (Sony news)-specific configuration problems.
5624 * Fixed other problems with using vanilla pcc and libc (enum problems;
5625 assumption that vsprintf exists).
5626 * Some major speed-ups (finc_pc_partial_function now caches a match;
5627 parsing avoids duplicate symbol_lookup calls).
5628 * Changed handling of baseclasses (no longer use baseclasses field
5629 of struct type, use the first n_baseclasses fields instead).
5630 * Various minor changes/fixes, most C++-related.
5633 Cache the most previous match from find_pc_partial_function.
5634 (Save both low and high ends of matching function's pc range.)
5635 This speeds up the loop of infrun.c:wait_for_inferior quite
5636 a bit, and makes step/next commands much zippier.
5638 Added an enum->int cast (otherwise, some compilers barf).
5640 No longer set baseclass offset to 0, since multiple
5641 inheritance now mostly works.
5642 Added a number of casts, to shut up compiler warnings
5643 (after stabs where made enums, not ints).
5644 When discarding a symbol table (in symbol_file_command),
5645 must clear the cache introduced in blockframe.c.
5646 Don't convert $vtbl_ptr_type to vtbl any more.
5647 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5648 Mask off sign bit emitted by g++ for virtual table offset.
5649 Set voffset to -1 (not 1) for static member functions.
5651 Changed parsing/lexing of names to avoid doing symbol lookup twice
5652 (once when lexing to determine symbol class, once for real).
5653 Now only call symbol_lookup once. Fields of 'this' win especially big.
5655 Subpress printing addr twice in the case of 'x/s addr'.
5657 lookup_basetype_type is no longer used.
5658 Add find_methods as recursive helper function to decode_line_1.
5659 This allows multiple inheritance to work.
5660 Also, once one or more matches has been found, do not look in
5661 base-classes. (Baseclass methods would be overridden, anyway.)
5663 Removed baseclasses array in struct type.
5664 Instead of using baseclasses[i], use fields[i-1].
5665 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5666 Changed sign convention of voffset (previous was inconsistent).
5668 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5670 Used to assume existence of vsprintf. Re-written to not need it
5671 if HAVE_VPRINTF is undefined.
5673 typecmp was too pessimistic. Made it less so.
5675 Don't print space after address.
5676 If vtable points to a misc symbol (with 0 offset), print it,
5677 since that indicates the actual class of the object.
5678 Changed ype_print_derivation_info to use new inheritance
5679 scheme (without baseclasses vector).
5681 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5682 Also, changes needed because TYPE_BASECLASSES were removed.
5684 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5686 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5689 If there is no path set, and the symbols don't indicate what directory
5690 a file was compiled in, look in the current directory. But either
5691 a path or a known compilation directory will prevent this.
5694 Three independent bug fixes:
5695 * Remove the #if 0 block that breaks some stuff.
5696 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5697 adapt gdb to either SunOS 4.0.* or 4.1.
5698 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5701 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5704 (type_print) Demangle the name being printed.
5705 (type_print_base) Handle botched demangling without coredump (tiemann).
5708 (check_stub_method): Document routine.
5709 (tiemann) fix bug for no-arg functions
5710 Avoid clobbering beyond end of malloc'd storage.
5711 Terminate the argument list properly.
5713 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5715 * Changes merged by John Gilmore:
5718 In breakpoint_1, use new print_address_symbolic instead
5719 of find_pc_partial_function. (This forces use of assembler-level
5720 addresses, and avoids misleading non-mangled source-level names.)
5722 Generalize ansi argument such that -1 means skip arglist totally.
5723 Removed global variable print_ansi_qualifiers (which made
5724 code non-reentrant), in favor of extra explicit arguments
5725 to internal routines.
5727 Add new helper function print_address_symbolic.
5728 Use find_pc_misc_function instead of find_pc_partial_function
5729 (since we want assembler-level symbols here).
5731 Print unknown function as just "f (...)", not "f (...) (...)".
5732 Use new fputs_demangled explicitly.
5734 Fixed a typing violation (problem: value.h cannot be imported
5735 without renaming many variable in this file).
5736 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5737 decode_line_1: Moved forward some never-reached code.
5738 Made decode_line_2 skip function prologues correctly.
5740 fputs_filtered should not demangle by default.
5741 Add new fputs_demangled to demangle on demand..
5743 Change value_struct_elt to use value_primitive_field (using recursive
5744 utility function search_struct_field). This allows foo.bar to work
5745 for multiple inheritance (so far only for data fields).
5746 Change check_field in the same way (recursive helper function
5747 to support multiple inheritance).
5748 (Note: there are more of these problems that I haven't fixed.
5749 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5750 value_of_this: 'this' symbol name is now just "this", note "$this".
5752 Don't print static members.
5753 Avoid printing "members of <type>" if there are none.
5754 Simplified type_print_derivation_info by merging duplicate code.
5755 Remove useless blank lines in type_print_base (ptype command).
5757 Added declaration of new routine value_primitive_field.
5759 Added value_primitive_field which is generalized version of
5760 value_field that can handle multiple inheritance (non-zero offsets etc).
5761 Re-implemented value_field to call value_primitive_field.
5763 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
5765 * infcmd.c -- insert else to avoid 'delete env' coredump when you
5766 delete the whole environment. Karl Berry reported the bug.
5767 * source.c - fix openp to avoid //'s in filenames, which
5768 trigger an Emacs bug causing it to not be able to find files
5769 when running gdb in a window.
5770 * dbxread.c - zap the #if 0 that botches the add-file code.
5771 It seems to work a lot better without all the code commented out.
5773 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
5775 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
5778 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
5780 * Makefile - added a ${CFLAGS} to a couple of entries,
5781 added remote-sa.sparc.c
5782 * added remote.sa-sparc.c, a modification of remote.c
5783 which conducts a dialog directly with the SparcStation prom.
5784 * breakpoint.c, infrun.c, sparcdep.c added
5785 remote_insert_breakpoint(), and remote_remove_breakpoint()
5786 to breakpoint.c instead of directly writing breakpoint instructions.
5787 * sparcdep.c on remote_debugging,there is no need
5788 to remove signle step breakpoint instructions.
5789 * main.c added "-epoch" flag and "int epoch_interface" to main.c
5791 * printcmd.c - epoch interface sends lisp expressions to open up
5792 epoch windows on inspection.
5793 * valprint.c - added arrayprint, and addressprint and made adding
5794 format controls easier
5795 * wait.h added a couple of undef's because we were getting
5796 complaints about WSTOPSIG and WTERMSIG begin redefined.
5799 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
5801 * symtab.c (decode_line_1): Add support for handling method stubs
5802 in the type information.
5804 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
5806 * values.c (baseclass_addr): Run loop from INDEX+1 to
5807 N_BASECLASSES; otherwise, we can still get into a loop.
5808 @@ This should be restructured to use a cleaner search strategy.
5810 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
5812 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
5813 abbreviation "Tt" for tags which have the same name as their
5816 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
5818 * symtab.c (list_symbols): add ability to set breakpoints on all
5819 the functions which match a particular regular expression.
5821 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
5823 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
5824 should print ANSI qualifiers (such as `const' and `volatile').
5825 All callers changed to call with ANSI == 1, except from
5826 `check_method_stub', which uses old-style syntax.
5828 * symseg.h (struct fn_field): Remove unneccessary `args' field.
5829 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
5831 * values.c (check_stub_method): New function.
5833 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
5835 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
5836 * valprint (type_print_base): Ditto.
5838 * symtab.c (gdb_mangle_typename): New function.
5840 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
5842 * breakpoint.c (catch_command): New function. Provides a
5843 mechanism to set breakpoints based on catch clauses.
5844 (disable_catch): Similar, but disables breakpoints on catch
5846 (delete_catch): Similar, but deleted breakpoints on catch clauses.
5848 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
5850 * blockframe.c (blockvector_for_pc): New function.
5851 * blockframe.c (block_for_pc): Changed to call
5852 `blockvector_for_pc' and get the block itself.
5854 * stack.c (catch_info): New function. Prints info about
5855 exceptions which can be caught in the current frame.
5856 * stack.c (print_frame_label_vars): New function. Similar to
5857 `print_frame_local_vars'.
5858 * stack.c (print_block_frame_labels): Prints out labels that are
5859 defined in this frame. These labels are exceptions that can be
5862 * dbxread.c: Updated to handle N_CATCH symtab types.
5864 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
5866 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
5867 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
5868 when printing the type.
5870 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
5872 * valprint.c (val_print): Use `baseclass_addr' to access the
5873 baseclasses pointed to via the derived class object at VALADDR.
5875 * values.c (baseclass_addr): New function. Casts derived pointers
5876 to baseclass pointers taking virtual baseclasses and multiple
5877 inheritance into account.
5879 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5883 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5885 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
5886 exp_valid_block field correctly.
5888 * infrun.c (wait_for_inferior): When checking "don't even think
5889 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
5890 also check step_resume_breakpoint.
5891 Insert breakpoints and continue (not step) if
5892 step_resume_break_address != NULL, even if another_trap.
5893 If trap_expected and we enter sigtramp, then set up a
5895 If trap_expected is set when we hit the step_resume_break,
5897 When calling resume and trap_expected says tell resume to step
5898 (2 places), also check step_resume_break_address.
5900 * infrun.c (wait_for_inferior): Don't set
5901 prev_{pc,sp,func_{start,name}} before calling wait ().
5902 Do set them after exiting loop.
5903 Move their declarations outside functions.
5904 (start_inferior): Initialize them.
5906 Thu May 3 00:15:11 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5908 * infrun.c (wait_for_inferior, after check for trap_expected > 1):
5909 Restore old code which distinguishes between trap_expected and
5910 running_in_shell, just make the latter take any non-TRAP signal,
5913 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
5915 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.
5916 xconfig/3b1 (CC,PINSN_CC): Define.
5918 * xconfig/altos, altos-dep.c: Rename altos-dep.c to altos-xdep.c.

5923 infrun.c (wait_for_inferior) [SHIFT_INST_REGS]: New code.
5925 * param.h, tm-88k.h: Define ADDR_BITS_*.
5926 infcmd.c (jump_command, read_pc), infrun.c (wait_for_inferior),
5927 printcmd.c (do_one_display): Use them.
5929 * utils.c: Split #ifdef USG into a USG_UTILS and a QUEUE_MISSING.
5930 xm-88k.h: Define USG_UTILS.
5932 Wed May 2 00:05:33 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5934 * printcmd.c (printf_command) [__INT_VARARGS_H]: New code.
5935 (printf_command): Add from_tty parameter.
5937 * valprint.c (value_print): Check VALUE_OPTIMIZED_OUT flag.
5939 * value.h: Add optimized_out field and change lazy field to
5940 char. Add macro VALUE_OPTIMIZED_OUT.
5942 * i386-pinsn.c: Change from Eirik Fuller to write to stream directly
5943 instead of stuffing things in buffers (oappend, etc).
5945 * breakpoint.c (bpstat_do_actions): If *BSP is set to NULL by
5946 execute_command, exit both loops.
5948 * Makefile.dist: Don't set TARGET_ARCH. Add .c.o rule.
5950 Tue May 1 17:07:23 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5952 * Makefile.dist (RAPP_OBS, rapp),
5953 rgdb.c, rserial.c, rudp.c, serial.c, udp.c, xdep.h,
5955 m68k-xdep.c, coredep.c: Wrap in #if !defined (RDB).
5957 * valops.c (value_struct_elt), values.c (value_static_field):
5958 Change error messages to remove references to `info methods'.
5960 Tue Apr 24 10:25:10 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5963 infrun.c (start_inferior): Add START_INFERIOR_HOOK.
5964 infcmd.c [SHIFT_INST_REGS]: New code.
5965 findvar.c (read_relative_register_raw_bytes): Return a value.
