1 Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
3 * utils.c: Add warning_setup() and warning(). Warning() behaves
4 the same as error() except that it returns normally rather than
5 jumping back to command level. Modules that don't want to call
6 warning() for some reason, but want to produce their own warnings,
7 can call warning_setup() to ensure compatibility with the way
8 warning() and error() deal with the terminal.
10 * symtab.c: Make internal errors produce more useful messages.
12 * tm-68k.h: Move code that is duplicated in almost every single
13 m68k based machine's configuration files to this common file.
14 Duplications in the configuration files still need to be removed
17 * infrun.c (child_create_inferior): System V versions must call
18 setpgrp() with no arguments, to comply with prototyping typically
21 * munch: Add support for SVR4 style nm output.
23 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
24 file specific fields from the partial symbol table structure and
25 replace them with a pointer to private data for each different
26 flavor of object file reader to initialize appropriately.
28 Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
30 * infrun.c (wait_for_inferior): Check return value from
33 Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
35 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
36 by my last edit to this routine.
38 Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
40 * configure.in: added ebmon target.

46 * Makefile.in: Roll VERSION to 4.2.
47 * README, TODO, WHATS.NEW: Update.
49 * core.c (core_open): Improve error message for bad file.
50 Pass .reg virtual memory address to fetch_core_registers to help
51 it find the registers in the core-file header.
52 * coredep.c (fetch_core_registers): Take new argument, use it,
53 and pass it to register_addr to locate the block of registers.
54 * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
56 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
57 Sequent N_FN_SEQ like everybody else's N_FN.
59 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
60 * tm-i386v.h: #endif guck.
61 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
62 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
63 * xconfig/tahoe: Add REGEX, which seems to be missing.
65 * coredep.c: Add <sys/types.h> for SCOnix.
66 * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file.
67 * printcmd.c (print_formatted): Flush output before disassembly.
69 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
71 * doc/refcard.tex (sec "Working Files"): consistent metavars and
72 other improvements, due to comments by François Pinard
73 (pinard@iro.umontreal.ca)
75 * doc/gdb.texinfo (appendix "Installing GDB"): changes in
76 configure, and improvenets related to Pinard's refcard comments
78 Tue Oct 15 08:45:12 1991 John Gilmore (gnu at cygnus.com)

93 * dbxread.c (read_enum_type): Avoid Modula-2 kludge that breaks C
95 * i387-tdep.c (double_to_i387): Fix typo for double_to_ieee_extended.
96 * utils.c (_initialize_utils): If !ISATTY, don't paginate.
97 * configure.in, tconfig/decstation, xconfig/decstation: Rename
98 dec3100 to decstation.
100 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)
102 * doc/gdb.texinfo: Catch up to changes recorded here in ChangeLog
103 (nodes Continuing and Stepping; Memory; Targets) clarifications
106 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
108 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move

126 * core.c (get_core_registers): Avoid coredump if no .reg section.
128 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
130 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
131 This avoids coredumps under `set print object on' in value_headof
132 (called erroneously by value_from_vtable_info) for `p &struct'
133 or `p *struct'. From Peter Schauer.
135 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
137 * Makefile.in: Roll version to 4.1.2.
138 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
139 size from BFD (but, FIXME, we don't yet read external nlists's and
140 convert them to internal nlists's before handling them -- we still
141 assume they have the same size and alignment.) Use SET_NAMESTRING
143 * exec.c (exec_file_command): Move dead coff-encapsulation code
145 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.

152 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
154 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
155 * mips-xdep.c (store_inferior_registers): Don't try to
156 write the (pseudo) FP.
157 * mipsread.c (parse_partial_symbols): Improved algorithm for
158 setting pst->texthigh.
160 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
162 * doc/Makefile: make TEXINPUTS include . everywhere
164 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
166 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
167 vestiges of typevectors, which were for symsegs and are no longer
168 used. (From a question by Eliot Dresselhaus
169 <dresselh@RFT30.nas.nasa.gov>).
171 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
173 * dbxread.c, coffread.c: static-ize functions that were
174 gratuitiously external. (From Fred Fish.)
176 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
178 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
179 until it is large enough.
181 * dbxread.c (read_type): Handle error case slightly better.
182 Make complaint message not C++-specific.
184 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
186 * infrun.c (wait_for_inferior): Fix step/next so that you only
187 stop at the beginning of a new line. This fixes various problems
188 with for loops, nested if-else's and switch statements.
190 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
192 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
193 between symtabs and psymtabs become ordinary error()s.
195 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
196 properly, making "end pc" correct in shared lib psymtabs.
197 (From Guy Harris <guy@auspex.com>.)
199 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
201 * dbxread.c: Enable, but soften, const_vol_complaint.
202 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
203 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
204 should be file-scope, not global.
205 (read_struct_type): Remove ancient multiple-inheritance warning.
206 (read_range_type): Check base type, complain & patch if undefined.
207 * stack.c (frame_info): Demangle the function name in `info stack'.
210 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
212 * eval.c (evaluate_subexp_for_address): Don't use
213 TYPE_POINTER_TYPE directly (it might be zero if this type has
214 never had a pointer created before); use lookup_pointer_type.
215 * symtab.c (lookup_method_type): Arguments were swapped in all
216 callers, so fix it here. I'm amazed this worked at all!
218 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
220 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
221 "bss" rather than "data" symbols, but which still conflict.
224 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
225 * core.c (core_files_info): Shorten output.
226 * exec.c (exec_files_info): Ditto.
227 (build_section_table): Ignore zero-length sections.
228 * language.c, printcmd.c: Lint.
229 * language.h (get_frame_language): Declare.
230 * saber.suppress: update.

238 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
241 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
242 (Reported by Mark Peek <mark@imagen.com>.)
244 * solib.c (solib_map_sections): Relocate all sections, even
245 though only the text section's size is tracked. Mark ld_text
246 for eventual elimination as we generalize to N sections.
248 * infrun.c (wait_for_inferior): Don't check if the PC is in a
249 call_dummy if we were stopped by a random signal that is being
250 passed to the program. This produced wierd results when calling
251 functions in the inferior and signals (e.g. SIGALRM) were in use.
253 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
255 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
256 Bugfix from Paul Eggert <eggert@twinsun.com>.
257 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
258 * valprint.c (print_floating): Print 9 digits for IEEE floats.

272 * language.c (set_language_command): Print useful help message,
273 and restore the language string after giving help.
274 * valprint.c (typedef_print): Print typedef in C or M2.
275 * symtab.c (list_symbols): Use it.
276 * main.c (main): Avoid any output before (gdb) prompt when -q.
277 * language.c (set_language_command): Handle errors by restoring
278 the language string to its current state (fix from A. Beers).
279 * doc/gdbint.texinfo: Roll in information from README. Rearrange
280 "how to install" and "how to print the doc" stuff so it drops
282 * configure.in: Rename rtpc CPU to romp to match config.sub.
283 * README, WHATS.NEW, TODO: Update for gdb-4.1.
285 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
287 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
288 autoloading shared libs, copyright etc on GDB startup, clean up $_
289 and $__ index refs, set/show listsize and related updates to list
290 cmd. New host/target configs.
292 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
294 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
295 from main Makefile.in version definition
296 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
298 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
300 * doc/gdb.texinfo: merge new language-switching and lang-specific
303 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
305 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
306 compilers (which may lack stddef.h).
308 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
310 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
311 N_WARNING are the same except for the N_EXT bit, so just use their
312 values alone, rather than OR-ing them with N_EXT.
314 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
316 * mipsread.c (parse_lines): Deal with negative extended line
319 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
320 global symbol conflicts.
322 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
324 * .gdbinit: Move 'set complaints' to top, so it runs even in
325 case we aren't debugging GDB.
326 * language.c (_initialize_language): Fix type check and range
327 check documentation strings.
328 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
329 language.c can use it. (Though language.c should really not be
330 handling warnings/errors the way it does, FIXME.)
331 * symtab.c (lookup_primitive_type): const lint.
333 Bugfix from Peter Schauer:
334 * source.c (lines_to_list): Make signed, to avoid comparison
335 going unsigned and complaining that -3 is too high for 21 lines.
336 * stack.c (lines_to_list): Ditto.
338 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
340 * Makefile.in (HFILES): Add minimon.h.
341 (VERSION): Roll version number to 4.0.95.
342 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
343 New rules for building distributions. Normal distribution
344 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
345 one level up from here; it calls make-proto-gdb.dir to build a
346 directory `proto-gdb' which is an image of the release. The old
347 `gdb.tar.Z' rule still works too.
348 * config.sub, configure: Roll in latest from ..
350 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
352 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
353 new-target, and new-config chapters; fix minor typos; come closer
354 to usual GNU markup conventions for @file @samp @code @var.

358 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
359 * mipsread.c (parse_partial_symbols): Enter the name of all
360 structs/unions... into the psymtab so we can access them if the
361 symtab is not read in.
362 * mips-tdep.c: Remove some unneeded #includes.
363 * xconfig/dec3100: Add HAVE_STRSTR.
365 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
367 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.

371 * mipsread.c (_initialize_mipsread): Avoid using
372 builtin_type_void at initialize time.

375 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
377 Merge multiple-language support, and partial Modula-2 support,
378 from Andrew Beers <beers@cs.buffalo.edu>.

474 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
476 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
477 entries are enclosed herein. Not all of these changes
478 have been merged into the master GDB sources -- check the
479 ChangeLog above here for the merge log.
481 Mon Jun 3 17:05:45 EDT 1991
483 m2-exp.y Created. Tested outside of GDB for a few days. Proper
484 operators were added, C specific operators and tokens
485 removed. yylex() revamped to some extent. Still things
486 missing from the grammar, such as sets.
487 Tested for two weeks in GDB v3.5.
489 Tue Jun 11 17:23:48 EDT 1991
491 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
492 so they are built-in. Sort of a hack.
494 Fri Jun 14 12:53:51 EDT 1991
496 m2-exp.y Added range checking for numeric constants. Any numeric
497 constant is assumed to be of builtin type INTEGER unless:
498 (1) it is octal or hexadecimal, in which case it is a
499 CARDINAL; (2) it is too big to fit into an INTEGER, in
500 which case it is a CARDINAL.
501 eval.c Added simple range checking for +, -, and * on integers.
502 Doesn't work very well for *, since 6 * 1,000,000,000 =
503 1,705,032,704, which fails the simple test of result >=
504 first_operand, no matter in what order the operands are.
506 Tue Jun 18 14:11:30 EDT 1991
508 Broke the parser into parts, one containing the C grammar and the other
509 containing code to be shared by all of the grammars.
511 The following files no longer exist:
516 The following files were added:
518 c-exp.y (The C grammar)
519 m2-exp.y (The Modula-2 grammar)
520 parser-code.c (Code that is shared by the above grammar)
524 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
525 now necessary to use the Bison compiler compiler, since it
526 will generate function/variable prefixes other than yy.
528 Tue Jun 18 16:47:49 EDT 1991
530 symtab.[ch] Added the external variable working_lang, than holds the
531 value of the current working language.
532 Added the ennumerated type language_mode, with the values
533 language_auto and language_manual, the former meaning that
534 GDB sets working_lang as needed, and the latter meaning
535 that the value of working_lang is totally under user
537 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
538 REAL, BOOLEAN and CHAR. Also added the type codes
539 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
540 utils.c Added set_language_command and show_language_command to
541 implement the GDB support commands "set language" and
543 expression.h A number of identifiers were added to the type exp_opcode
544 to facilitate Modula-2 builtin functions, integer
545 division, and array indexing.
547 Wed Jun 19 13:25:58 EDT 1991
549 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
550 if the language specified by working_lang requires the use
551 of strict typing of expressions. Eventually, even this
552 will be able to be changed by the user.
553 Added the macro RANGE_CHECK, which evaluates to non-zero
554 if the language specified by working_lang requires the
555 checking of a value against the domain of its type.
556 Eventually, even this will be able to be changed by the
558 language.[ch] Predicates involving types (simple_type, ordered_type,
559 same_type, integral_type, numeric_type, character_type,
560 boolean_type, float_type) are added. These predicates are
561 based on the current value of working_lang, and are handy
564 Wed Jun 19 15:39:34 EDT 1991
566 eval.c Added the function type_array_rank which computes the rank
568 valarith.c Added the funtion value_bool, which when given a integer
569 value.h value (ie. struct value *) as an argument, it returns a
570 boolean value (ie. struct value *) true if that integer
571 is non-zero, and a boolean value false otherwise.
572 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
573 will print out properly.
575 Wed Jun 19 16:36:34 EDT 1991
577 valops.c Added the function value_capitalize, which returns it
578 value.h argument capitalized if its argument is a lowercase
579 letter, or the argument unchanged if its argument is not a
581 valarith.c Added the function range_check_p, which returns non-zero
582 value.h if its value argument is between the integral bounds upper
584 Added the function range_check_enum_p, which makes sure
585 that its value argument is a valid member of the domain of
587 Added the function range_check_range_p, which makes sure
588 its value argument lies between the upper and lower bounds
589 of its type argument, which must be a ranged type.
590 Added the function check_array_index, which range and type
591 checks an index of an array.
592 Added the function value_multi_subscript, which computes
593 array[idx1,idx2...idxN], given a value array and an array
594 of values representing indicies.
595 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
596 unpack_long to work with TYPE_CODE_BOOL and
599 Wed Jun 19 18:04:08 EDT 1991
601 symtab.c Stored pervasive types in a structure and make
602 lookup_pervasive_type() a lookup function that was based
603 on working_lang. If lookup_pervasive_type() returned
604 non-zero, then that value was returned (a fix, since
605 before it simply wouldn't return the pervasive type.)
606 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
607 non-zero if the language specified by working_lang means
608 "conversion" when it says "cast".
609 valops.c Added the function value_real_cast(), which performs a
610 value.h *cast*, not a *conversion*, which is what value_cast()
611 does when it can. In particular,
612 value_cast(<float_type>,4) = 4.0, while
613 value_real_cast(<float_type>,4) = some mess.
614 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
615 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
616 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
617 and MIN on integral types. *NOTE*: These are currently
618 hardcoded to work only if there are 8 bits per storage
620 eval.c Made logical functions call value_bool to return a
621 properly typed boolean value, based on working_lang.
623 Thu Jun 20 11:55:27 EDT 1991
625 valprint.c Types now print out in a Modula-2 fashion. This works for
626 the cases when the type is printed out step-by-step, that
627 is, it doesn't work when the name of a structured type
628 (which includes the keyword "struct", etc.) is simply
630 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
631 since type specifications in C and Modula-2 are very
632 different. The C printing of a type is very recursive,
633 whereas in Modula-2 it is generally very simple. C has
634 type prefixes and suffixes, which have no real analogue in
635 Modula-2. Maybe type_print() should call a language
636 specific type printer. This is also advantageous if we
637 compile GDB to exclude some of the languages. We'll just
638 leave those functions out.
640 Thu Jun 20 16:57:10 EDT 1991
642 dbxread.c When reading the complete symbol table in (via
643 psymtab_to_symtab()), the number and types of function
644 arguments are added to a function type. define_symbol()
645 calls add_param_to_type() to accomplish this.
646 Assumption: when we come across a function definition
647 (N_FUN symbol with an 'f' or 'F' in the name), its
648 arguments will appear before another function definition.
649 When a function is found, a pointer to its type is placed
650 in the global in_function_type. Changes that
651 add_param_to_type() makes are to this global.
652 valprint.c The type of a function now includes (for Modula-2) the
653 types of its parameters.
654 eval.c Type checking and a check for the proper number of
655 arguments is now done for function calls. Not sure of the
656 impact this has on C++ member function yet.
658 Thu Jun 20 19:58:48 EDT 1991
660 valprint.c Rewrote the type printer. Broke it into two language
661 specific parts, adding the functions type_print_m2() and
663 An unfortunate consequence is this: if you debugging a C
664 program in Modula-2 mode (why?), info types does not work
665 well with regular expressions, since the types are printed
666 out in Modula-2 terminology, but stored in C terminology.
667 language.[ch] Added the functions new_type_last(), type_keyword(), and
668 type_sep() to aid in the printing of typedefs.
669 symtab.c Made the printing of typedefs as language independent as
670 possible through calls to new_type_last(), type_keyword(),
673 Fri Jun 21 11:50:26 EDT 1991
675 dbxread.c Check all incoming ennumerated types. If it looks like
676 Modula-2's BOOLEAN type, then change the type_code of the
677 type to TYPE_CODE_BOOL so we can process it as a boolean
679 valprint.c Replaced some of the 0x%x with calls to sprintf and
680 hexformat() in val_print().
681 language.[ch] Added the function hex_to_string(), which converts its
682 integral argument to a hexadecimal number (format is
683 language based) and returns the result as a string.
685 Mon Jun 24 12:25:07 EDT 1991
687 valprint.c Some functions call type_print_1() directly, instead of
688 value.h using type_print(), so they can specify where (column) to
689 print things. Since type_print() takes care of language
690 dependence, that needs to be called first. Added a
691 parameter depth to type_print() (so it is now like
692 type_print_1). Changed type_print to type_print_at, and
693 made type_print a macro that passes a depth argument of
695 symmisc.c Changed all calls to type_print_1 to calls to
697 Makefile.dist Made it possible to build GDB for a specific set of
698 depend languages. Do this by passing a definition for the macro
699 LANGS to make. LANGS should be a string containing a
700 space-separated list of language names (ie. LANGS="c m2").
701 The default is to build all languages. Note that grammar
702 files must follow the naming convention of <lang>-exp.y.
703 gdb.lang This holds the current value of the LANGS macro. It is
704 examined every time make is called, and is updated if
706 eval.c Added #ifdef _LANG_<lang> to these files.
707 expread.c Still need to add them to dbxread.c and coffread.c.
715 Mon Jun 24 16:33:11 EDT 1991
717 language.[ch] Added the functions hexformat_pre() and
718 hex_to_string_pre(), which take a prefix argument to
719 include in the format string. Thus, hexformat_pre("08") will
720 return "0x08x" (if the working language is language_c).
721 Made hexformat() and hex_to_string() calls to the above
722 with "" as the prefix argument.
724 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
725 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
726 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
727 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
728 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
729 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
730 valprint.c, vax-pinsn.c
732 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
733 calls to hexformat() and hex_to_string(). Format strings without
734 the leading "0x" were ignored.
736 depend Updated to take the above into account.
739 Tue Jun 25 15:27:18 EDT 1991
741 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
742 and type_check_t to keep track of the current state of
743 range and type checking.
744 main.c Added the variables range_mode, range_check, type_mode,
745 and type_check to record the current state of range and
746 type checking. Added initialization code to main().
747 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
751 Tue Jun 25 17:57:08 EDT 1991
753 dbxread.c process_one_symbol() updates the variable (enum language)
754 source_lang based on the extension of the filename
755 contained in the N_SO sybmol that started this symtab.
756 When end_symtab() is called, the value of source_lang is
757 put into the language field.
758 stack.c select_frame() sets working_lang (and possibly type_check
759 and range_check) to the language field of the symtab
760 associated with the frame that is selected if working_mode
761 is language_auto. If working_mode is language_manual, a
762 warning is printed and working_lang is not set.
763 language.c Added the function set_type_range(), which sets the value of
764 type_check and range_check (if their modes call for
765 automatic setting) based on the current value of
766 working_lang. A non-zero argument will cause the current
767 settings to be output.
770 Wed Jun 26 14:51:40 EDT 1991
772 eval.c Added range checks on assignment.
773 m2-exp.y Added the grammar for sets to the language. Currently,
774 these do not do anything except print an error message.
776 Wed Jun 26 17:01:04 EDT 1991
778 m2-exp.y Added the ability for parse_number() to parse negative
779 numbers. A global flag is set upon encountering a unary
780 minus. This was done to make, for example, 1 parse as a
781 CARDINAL, and not as an integer, per Wirth's examples in
782 Programming in Modula-2 ed.4.
783 valprint.c Added support for "set radix 2" by then setting
784 output_format to 't'.
785 eval.c Implemented range checking on subrange types. Added calls
786 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
787 Implemented MIN and MAX for ennumerated types. The
788 minimum value of an ennumerated type is defined by Wirth
789 as the first identifier, and the maximum as the last.
790 m2-exp.y Made octal numbers ending with "B" be characters and those
791 ending with "C" be numbers, per Wirth's book. (p. 34)
793 Thu Jun 27 14:11:52 EDT 1991
795 stack.c select_frame() now only sets working_lang, it does not
796 notify the user. If working_mode is language_manual, then
797 a warning is issued once.
798 main.c At the end of each call to execute_command(), working_lang
799 is checked against the local static (enum language)
800 current. If they differ and working_mode is
801 language_auto, the new settings of language, type and
802 range checking are printed out.
803 stack.c Modified frame_info() to include the language of the
804 current frame in the output of "info frame".
805 language.[ch] Added the function language_str() which returns the name
806 of the current language.
808 Fri Jun 28 15:33:14 EDT 1991
810 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
811 the language. INCL and DECL currently cause an error,
812 since sets are not implemented yet. INC and DEC are
813 implemented as PREINCREMENT/PREDECREMENT with one
814 argument, and as ASSIGN_MODIFY with two arguments.
815 eval.c Added type checking to the above cases.
816 value.h Added not_lval_constant to the lval_type ennumerated type.
817 not_lval_constant means that the value is a constant
818 value; that is 3 or 'a' or TRUE, not as in a constant
819 identifier. This is used to help coerce numbers such as 3
820 to either signed or unsigned numbers.
821 valops.c Added the function value_coerce_constants() which coerces
822 constant integers as following: if one is a constant and
823 the other is not, the constant's type is set to the type
824 of the other argument. If both are constants and one is
825 signed, the other is converted to a signed constant.
827 Sat Jun 29 17:26:29 EDT 1991
829 valarith.c Added a better range checker. It now checks range
830 (successfully) on integral operations [+-] (signed and
831 unsigned) for any C sized type. Still does not work well
833 int_in_size() returns an integer that is coerced to fit into
834 specified number of bytes.
836 Mon Jul 1 13:04:14 EDT 1991
838 language.[ch] Added the function binop_result_type(), which returns the
839 builtin (struct type *) type that would be the result of a
840 binop on the two values V1 and V2.
842 Wed Jul 3 19:22:53 EDT 1991
844 source.c Extended source_info() to include the source language in
845 the output from "info source".
847 Fri Jul 5 13:48:52 EDT 1991
849 utils.c Moved the support functions for the GDB set/show commands
850 dealing with language into language.c.
851 language.c Added the function language_info(), which displays info
852 about the current working language, type and range check
853 settings. Called via the GDB command "info language".
854 Added an initialization routine _initialize_language(),
855 that sets defaults for the language, type and range
856 variables and sets up the new GDB commands.
857 main.c Language setup moved to language.c.
860 Mon Jul 8 10:10:22 EDT 1991
862 valarith.c Debugged the range checker for arithmetic. Still does not
863 work for multiplication very well.
865 Mon Jul 8 12:40:37 EDT 1991
867 language.[ch] Added the function value_true() which returns non-zero if
868 its argument represents a boolean true value.
869 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
870 check the truth of an expression.
872 Thu Jul 11 12:51:34 EDT 1991
874 language.[ch] Added the predicate structured_type(), which returns
875 non-zero if the argument is a structured type.
876 Added the predicate pointer_type(), which returns non-zero
877 if the argument is a pointer type.
878 eval.c Added the ability to do addition and substraction on
879 pointers and integers. This case simply bypasses the
882 Thu Jul 11 14:41:42 EDT 1991
885 Added the symbol N_DEFD (0x4a) which is a definition
886 module dependency that is used by the GNU Modula-2
887 compiler and the linker. It is not important to GDB,
888 except that [dbx|coff|mips]read.c should ignore these
891 Fri Jul 12 16:07:00 EDT 1991
893 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
894 0 in val_print(). Also added statements to the else part
895 to coerce type (argument to val_print) to a pointer type
896 if it is an "array of unspecified length".
897 valops.c Added the function value_m2_string(), which returns a
898 (value) value which is a constant string, whose type is
899 (ARRAY [0..n] OF CHAR). The length field of the type
900 structure is set to zero, so it will be interpreted as an
901 "array of unspecified length".
902 stack.c Moved the language/frame mismatch check to
903 main.c:execute_command().
904 main.c The working language is recorded each time
905 execute_command() is executed. If working lang has
906 changed during its execution, then the new
907 language/type/range info is printed out for the user. If
908 the working language does not match the language of the
909 frame, a warning is issued.
911 Sat Jul 13 16:16:39 EDT 1991
913 eval.c Moved all the type-checking stuff for operators to
914 language.[ch] language.c. This is so we can keep language-specific
915 stuff (like for what type operators are defined) in
917 language.[ch] Added the function binop_type_check(), which checks to see
918 if its two (value) arguments are type-compatible with its
919 opcode argument. The opcode should represent an operation
920 involving an operator. Also added the macro function
921 unop_type_check, which calls binop_type_check with a
922 NULL second argument.
923 expprint.c Added Modula-2 operators to the op_print_tab, so info
924 expression.h break works correctly. Also added "op_string", which
925 returns the string corresponding to the (enum exp_opcode)
926 opcode that is its argument.
929 Sat Jul 13 18:26:18 EDT 1991
931 coffread.c Added code to record the type of function arguments with
932 each paricular function. Code is very similar to that
934 dbxread.c Moved add_param_to_type() to symtab.c
935 symtab.[ch] Added function add_param_to_type() from dbxread.c
937 *** NOTE: The above additions have not been tested.
939 Mon Jul 15 12:50:47 EDT 1991
941 langauge.[ch] Added the functions type_error and range_error, which work
942 like error() except if the type/range mode is set to
943 *_mode_warn, then they do not do a return_to_top_level(),
944 but merely print a warning.
945 Also changed [set|show]_[type|range]_command() to support
946 the new "warn" feature.
948 Thu Jul 18 17:50:54 EDT 1991
950 mipsread.c Added code to record the type of function arguments with
951 each particular function. Code is very similar to that
954 *** NOTE: The above additions have not been tested.
956 Fri Jul 19 11:19:10 EDT 1991
958 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
959 UMIN_OF_SIZE, which when given a size of a numeric type,
960 return the maximum and minimum value it can hold. UMAX...
961 and UMIN... return the result for unsigned types.
962 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
963 struct types. They call above macros.
964 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
965 avoid a name conlict with the above.
966 c-exp.y Added range checking on numeric constants in
967 parse_number() for completeness.
968 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
969 return 0 if working_lang is not language_c.
971 Thu Aug 8 14:17:22 EDT 1991
975 breakpoint.c Documentation strings of some commands changed to
976 eliminate the references to the C language where
979 Tue Aug 13 15:48:03 EDT 1991
981 m2-exp.y Added qualified identifiers to the grammar. The semantics
982 are slightly different from those of the GDB operator ::
984 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
985 type_exp, where type_exp is any valid type expression.
987 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
988 printcmd.c Modified ptype_command() so it actually parses the input
989 (necessary for type expressions with scope qualifiers).
990 Added the function ptype_eval() which expects an
991 expression composed of one OP_TYPE element.
992 *.[ch] Replaced all occurences of parse_c_expression with
994 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
996 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
998 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1000 Small fixes from Peter Schauer:
1002 * infrun.c (child_attach): Lint.
1003 * solib.c (find_solib): Handle shared libs version 2.
1005 Small fixes from David Wood:
1007 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1011 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1012 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1014 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1015 chars_per_line is at maximum (user typed `set width 0'). Fix
1016 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1018 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1020 * coredep.c: include ptrace.h where necessary.
1021 * mipsread.c(parse_lines): fix unsigned char problem that was
1022 messing up line numbers on SGI's and possibly other MIPS based
1024 * infrun.c (child_create_inferior): use better test to check
1025 return val from setpgrp().
1026 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1027 for sgi/irix support.
1029 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1031 * mipsread.c (parse_symbol): Put non-static procedures
1032 in the global block.
1034 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1036 Patch together `text_start' and `text_end' for 29K port.
1038 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1039 variables and set them based on the exec file.
1040 * am29k-tdep.c: declare text_start.
1041 * valops.c (call_function_by_hand): declare text_end.
1043 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1044 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1045 because machines that do this will also have to know to
1046 set NEED_TEXT_START_END. Besides, it was a redundant way to
1048 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1049 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1050 NEED_TEXT_START_END.
1052 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1054 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1056 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1057 Pass MUNCH_DEFINE to munch whenever we run it.
1058 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1059 format string; use 0x%x instead.
1060 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1061 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1062 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1063 * inflow.c: Handle `short' process group IDs.
1064 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1065 and check for ptrace errors.
1066 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1067 (coff_symfile_init): Initialize text_bfd_scnum.
1068 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1069 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1070 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1071 Merge target arm case with other "easy" cases. Add target
1072 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1073 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1075 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1076 * munch: Cope with RT/PC putting fns in data segment.
1077 Restore ability to override `nm' by specifying MUNCH_NM.
1078 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1079 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1080 and remote-adapt. Remove encapsulated coff #define's (the
1081 support should go in BFD, and gdb shouldn't know or care).
1082 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1083 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1084 * tm-29k.h: Update BADMAG (though it should go away).
1085 Allow the register definitions to be overridden in another
1086 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1087 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1088 DUMMY_SAVE_GR96, for handling kernel calling conventions
1089 that use GR64+ rather than GR96+.
1090 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1091 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1092 overrides various things.
1094 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1095 child_attach does, making a clean stop in the newly attached
1097 * remote-eb.c: Lint.
1099 * coffread.c: Make coffread independent of any particular
1100 variant of COFF. Avoid #include-ing any particular one except
1101 internalcoff.h. BFD now passes key values for symbol reading
1102 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1103 and the symbol masks and shifts); use them.
1104 Remove obsolete end_of_text_addr.
1106 * exec.c: Remove unused include files.
1108 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1110 * Makefile.in (documentation targets): Pass $(M4).
1111 Bugfix from eggert@twinsun.com (Paul Eggert).
1113 * stack.c (down_silently_command): Check for stack existence.
1115 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1117 * Makefile.in (VERSION): Update to 4.0.3.
1119 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1121 * core.c (core_file_command): Print frame at coredump with
1122 its level number, by calling print_stack_frame.
1123 * frame.h: Add selected_frame_level, print_stack_frame.
1124 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1125 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1126 Change print_sel_frame and print_selected_frame callers to
1129 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1130 * symfile.c (free_named_symtabs): Ditto.
1131 * main.c (main): wrap_here needs an arg.
1132 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1133 (solib_add): Avoid noise.
1134 (solib_create_inferior_hook): Lint.
1135 (sharedlibrary_command): Move dont_repeat to here.
1136 * utils.c (error): Call wrap_here to force buffered output.
1138 Small patches from Peter Schauer:
1140 * coffread.c (start_symtab): Free any existing line_vector before
1142 (read_coff_symtab): Ditto for type_vector.
1144 * source.c (lines_to_list): New variable, replacing function.
1145 (all uses): Use as variable.
1146 (_initialize_source): Add 'set listsize' and 'show listsize'.
1147 * utils.c (lines_to_list): Remove function.
1148 * stack.c (print_frame_info): Use as variable.
1149 * defs.h (lines_to_list): Remove declaration.
1151 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1153 * breakpoint.c (insert_breakpoints): Restore warning about
1154 the program might be running in another process, but only for
1155 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1156 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1158 * utils.c (error): if error_pre_print is set, print the string
1160 * main.c (main, print_gnu_advertisement, print_gdb_version):
1161 Reformat legalese so it always prints, but acts as an "I'm here"
1162 message while symbols are being read. If any errors occur,
1163 print a few newlines to set off the message and start it at the
1164 left margin. Remove mention of "help" command, and don't yak
1165 about symbol reading.
1166 (catch_errors): Error string is now printed first in case of
1168 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1169 suggest the "help" command.
1171 * Makefile.in (VERSION): Set to 4.0.2.
1173 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1175 * .gdbinit: Remove useless "rr" command. Set complaints
1176 to 1 for people debugging gdb.
1178 * breakpoint.c, remote-vx.c: Reword strings printed by
1179 catch_errors callers.
1181 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1183 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1184 (Fix from kenc@viewlogic.com.)
1186 Fix some infrastructure to be able to cope with host and target
1187 machines with different sized basic types (ints, ptrs, etc).
1188 (Idea from pierre@la.tce.com (Pierre Willard).)
1190 * values.c (value_from_longest): Rename from value_from_long.
1191 Handle pointer types as well as integers, so that targets with
1192 different pointer sizes from the host can be accomodated.
1193 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1194 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1195 uses of value_from_long to value_from_longest.
1196 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1197 the correct pointer type to value_from_long{est}.
1199 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1201 * remote-vx.c: Remove obsolete code for calling functions via
1202 vxworks kludge interface (it referenced value_from_long).
1204 * valops.c (value_string): Find malloc with lookup_misc_func, not
1207 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1209 Make writing to files work properly. (Fixes to BFD are also needed.)
1211 * core.c (core_open): Open file ourselves, read or r/w, depending on
1212 write_files. Use bfd_fdopenr.
1213 * gdbcore.h (write_files): New variable.
1214 * exec.c (write_files): Define variable, add set&show for it.
1215 (exec_file_command): Use write_files to open for read or r/write.
1217 Make shared library reading happen automatically. These changes
1218 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1220 * inferior.h (stop_soon_quietly): Add to exported variables.
1221 * infrun.c (child_create_inferior): call solib hook, if defined.
1222 (child_attach): call solib hook, if defined.
1223 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1224 (find_solib): Use lookup_misc_func rather than hand-rolled.
1225 (symbol_add_stub): New stub for catch_errors.
1226 (solib_add): Avoid output if !from_tty. Catch errors rather
1227 than just calling symbol_file_add and bombing.
1228 (solib_create_inferior_hook): Interface with the target process
1229 to let it read and alloc shared libs, then figure out what it did.
1231 * core.c (validate_files): Fix typo, soften warning.
1232 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1234 * utils.c (fputs_demangled): Avoid duplicate printing if
1235 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1237 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1238 (Fix from pierre@la.tce.com (Pierre Willard).)
1240 * main.c (catch_errors): Change argument to a char * from an int,
1241 since a char * can point to a struct full of glop, but an int
1242 is not guaranteed to be able to hold a pointer.
1243 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1244 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1245 * core.c (core_open, solib_add_stub): Adapt.
1246 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1248 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1250 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1251 by adding .NOEXPORT target.
1253 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1257 * Makefile.in (VERSION): Roll to 4.0.
1258 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1260 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1262 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1265 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1268 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1270 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1271 reflect above name change
1273 * WHATS.NEW: correct pointer to refcard.
1275 * doc/gdb.texinfo: update New Features, Installing
1277 * doc/gdbint.texinfo: add short description of configure +template
1279 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1281 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1283 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1285 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1286 tar file, add dependencies for referenced doc files.
1288 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1290 * coffread.c, symfile.c, stack.c: saberized.
1292 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1294 * doc/refcard.tex: permuted Essential Commands sec
1296 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1298 set/show symbol-reloading
1299 default set complaints 0
1301 RET-repeat disabled after prompted long displays
1302 processID (attach) interpretation of 2nd GDB cmdline arg
1304 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1306 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1307 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1308 breakpoint.c, main.c: lint.
1310 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1312 Install new configuration scheme for GDB and friends.
1314 * config.sub: Translate ordinary names to three-part names.
1315 * configure: Use three-part names internally.
1316 * configure.in: Translate three-part names to filenames.
1318 * README, WHATS.NEW: Update for gdb-4.0.
1319 * Makefile.in: Roll VERSION to 3.99.
1321 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1323 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1324 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1325 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1326 to single structures rather than arrays; when passing
1327 their address, use &. This avoids trouble with bdead compilers.
1328 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1329 instead. This avoids portability headaches.
1330 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1332 * source.c (open_source_file): Avoid ANSI const bdeath by
1333 skipping declaration and then casting result value.
1334 * tm-hp300bsd.h: Clarify comment.
1335 * utils.c (strstr): Result is const char *; ANSI bdeath.
1336 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1337 since system include file defines it differently from "defs.h",
1338 though the two are equivalent for our purposes.
1339 * tconfig/hp300bsd: Add m68k-tdep.o.
1341 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1343 * tconfig/sun*4: Remove warnings about system assembler.
1345 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1347 * mcheck.c: Avoid warning about undeclared abort fn.
1348 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1349 it causes recursive calls to error() when used in cleanups.
1350 To do so requires that we make it a function, so we do.
1351 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1352 * utils.c (do_cleanups): Remove the current cleanup from the
1353 chain *before* calling it, in case error() is called from it.
1354 The result won't be pretty, but won't be an infinite loop either.
1356 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1358 * dbxread.c (read_struct_type): Grok anon structs for C++.
1359 (vb_name, vptr_name): Null terminate these strings.
1361 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1363 Minor bug fixes from BSD Net2 gdb:
1365 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1366 returns 0, there is no previous frame.
1367 * breakpoint.c (commands_command): If !from_tty, don't call
1368 input_from_terminal_p().
1369 * dbxread.c (record_misc_function): Speed up slightly.
1370 (compare_psymbols): Ditto.
1371 * infcmd.c (do_registers_info): Take a second argument to
1372 determine whether to print float registers. "info registers"
1373 does not do so anymore. "info all-registers" does, now.
1374 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1376 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1377 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1381 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1382 executing_breakpoint_commands if we are interrupted by error.
1383 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1384 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1385 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1386 catch_errors() so we can setup the frame regardless of whether
1387 the shared libs work.
1388 * ieee-float.c (double_to_ieee_extended): Get exponent from
1389 right place in little-endian systems. From John Carey.
1391 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1393 * main.c: Remove unused terminating_signals and catch_termination().
1394 (long_options): Terminate with a zero element.
1395 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1396 (gdb_readline): Make call-compatible with readline.
1397 (init_signals): Improve comments re vfork vs. signal.
1399 * utils.c (prompt_for_continue): Use new gdb_readline().
1400 If we prompt for continuation, we don't let CR repeat the previous
1401 command, once we get back to a prompt. It's too easy to keep
1402 hitting CR, expecting "--more--" prompts, and have some long
1403 command start repeating on you.
1405 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1407 * blockframe.c (frameless_look_for_prologue): Speed up by
1408 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1409 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1410 Define two variants, one faster.
1411 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1412 and return zero, rather than giving an error.
1413 (setup_arbitrary_frame): Initialize the PC in the new frame.
1414 (skip_prologue): Add a second arg saying whether we're just
1415 checking for a frameless function or not.
1417 * core.c (core_open, core_close, core_xfer_memory): Move
1418 section table pointers and bfd* into the target_ops.
1419 (core_open): Allow errors in shared lib reading, etc.
1420 (core_files_info): Describe shared library sections.
1422 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1423 exec_files_info, set_section_command): Move section table
1424 pointers and bfd* into the target_ops.
1425 (add_to_section_table): Add BFD to section table.
1427 * target.c (target_xfer_memory, target_info): Pass target to
1428 xfer_memory and target_info functions.
1431 * gdbcore.h: Move struct section_table.
1432 * target.h: New home of struct section_table.
1434 * solib.c (solib_add): New argument is the target_ops whose
1435 section list is to be added to, if any. Reallocate the
1436 sections in that target to add any that come from shared libs.
1437 (throughout) so_sections renamed to sections.
1438 (solib_xfer_memory): Deleted.
1439 * tm-sunos.h (SOLIB_ADD): Add target argument.
1440 (SOLIB_XFER_MEMORY): Delete.
1442 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1443 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1444 from target_ops. It's the same on all targets. Add two section
1445 pointers to target_ops.
1447 * stack.c (find_relative_frame): Dump ancient algorithm for
1448 "down", just use handy "next" pointers.
1449 (frame_command): Don't error if there is no stack; let user
1452 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1453 modifies static state in the parent process; new_tty itself
1454 runs in the child and modifies the child's file descriptors
1455 to match the saved static state.
1456 * infrun.c (child_create_inferior): Call new_tty_prefork,
1459 * infptrace.c (child_xfer_memory): Add ignored target arg.
1460 * remote-eb.c (eb_xfer_inferior_memory): ''
1461 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1462 * remote-vx.c (vx_xfer_memory): ''
1463 * remote.c (remote_xfer_memory): ''. Rename from
1464 remote_xfer_inferior_memory.
1466 * main.c (main): Only try to attach "corefile" argument if
1467 it starts with a digit.
1469 * symfile.c (symbol_reloading): New "set/show" variable.
1470 (symbol_file_add): Shorten message about symbol reading.
1471 (add_symbol_file_command): Merge with add_syms_addr_command,
1472 since this should work on all targets now.
1473 (stop_whining): Default to zero, to shut up complaints
1474 about bad symbol tables on many systems.
1475 (free_named_symtabs): Just exit unless symbol_reloading.
1477 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1478 and add comment explaining shared library screw.
1480 * source.c: #if defined => #ifdef.
1482 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1484 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1486 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1488 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1489 (doc/Makefile knows how to make one for local config)
1491 * Makefile.in: use doc/Makefile for doc targets
1493 * doc/Makefile: GDB documentation now has its own Makefile
1494 doc/refcard.tex: renamed from "gdbrc.tex"
1495 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1496 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1499 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1501 * values.c (baseclass_addr): When reading target memory, use the
1502 length of the basetype, not the upper type. We've only malloc'd
1503 enough space for the basetype, leading to errors in free().
1505 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1506 ends up as a function specially, since we know the actual type of
1507 the pointed-to address. This (somewhat) fixes display of
1508 expressions that include misc_function_vector names. Try `cond 1
1509 !strcmp("a","b")' then `i b'.
1511 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1512 The child can be proceeded from inside wait_for_inferior in
1513 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1514 getting skipped in that case.
1516 * expprint.c (print_subexp): Use filtered output, since the
1517 subroutines we call use it, otherwise the output is horribly
1518 mangled, since output of wrappable stuff comes out late.
1520 * Makefile.in: Bump VERSION to 3.98.1
1522 * infrun.c (child_create_process): Use execlp to find the
1523 shell to exec our target program. This requires some fiddling
1524 with `environ' since there is no execlpe().
1526 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1528 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1529 Minor rearrangement of refcard permits two new make targets--
1530 gdbrc.dvi DVI output for refcard, using CM fonts
1531 gdbrc.ps PostScript refcard, using PS fonts
1533 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1537 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1538 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1540 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1542 * doc/gdb.texinfo: last changes for release.
1543 Minor typo and formatting fixes; incorporated most fixes remaining from
1544 filed mail commenting on earlier drafts.
1546 Added warnings: pipes don't work in run command;
1547 conditions are converse of assertions;
1548 step over fn without debug info goes to next fn;
1549 vars may have "wrong" values near fn entrance, exit
1551 Added example from Kingston on printing repeated nonadjacent values
1553 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1554 shell mode for signals
1556 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1557 doesn't sound so much like its parent "Stopping and Continuing"; also
1558 moved entries on continue to top of section, so they don't get lost.
1560 Improved installation directions in appendix, added manual formatting
1563 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1565 * configure.in: Remove xm.h and tm.h even if we aren't linking
1566 new ones, so "./configure sun4; ./configure none" does the right
1567 thing. Assume that alldeps.mak and depend are already built in
1568 srcdir, and avoid running "make" (particularly "make depend",
1569 which involves "gcc") from inside configure. Build Makefile
1570 directly rather than building Makefile.conf first.
1571 * configure: Regenerate with above changes.
1572 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1573 to 3.98. Revise gdb.tar.Z procedure to produce a file
1574 called gdb-$(VERSION).tar.Z but which unpacks into a
1575 directory called "gdb". Move non-source files out of
1576 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1577 (depend): Don't try to do "gcc expread.y".
1578 (expread.o): Update dependencies by hand.
1580 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1583 Fixed a variety of small typos that prevented info from formatting
1584 cleanly; altered too-long heading for GPL Appendix, as discussed
1585 w/RMS; Changed date on cover to July 91.
1587 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1590 (1) Applied some fixes due to comments from Larry Breed (easier ones
1591 through chapsec 5.2)
1592 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1593 it's broken in latest texinfo
1594 (3) Introduced *some* use of [] for optional arguments, where
1595 explanation is not simpler by listing cmd w arg and cmd w/out arg
1596 separately. Still not using @deffn.
1597 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1598 couple of headings are too long. Need patches to texinfo or revision
1601 * Partial update to README (which still needs work for this
1602 release!): (1) use of configure corrected for new script,
1603 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1605 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1607 * symtab.c (lookup_symbol): Don't complain right off about
1608 no debug symbols; use the misc function vector first.
1609 (list_symbols): Use misc function vector to find symbols
1610 that don't have debug info, and print them.
1611 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1612 PC range doesn't match symtab PC range, as it does on the
1613 MIPS because our symtab reading isn't perfect.
1615 * dbxread.c (dbx_symfile_read): Make warning about
1616 "no debug symbols" slightly nicer.
1618 * source.c (select_source_symtab): If "main" symbol exists,
1619 but decode_line_spec can't find line info, don't just return
1620 a zero; try other source symtabs or give an error.
1622 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1623 their low addresses first, then rip through fixing high addrs.
1625 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1626 <runene@ifi.uio.no>.
1627 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1629 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1631 * Minor, mostly mechanical, cleanup of doc subdir for clean
1632 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1633 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1635 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
1637 Mostly MIPS and general symbol-reading fixups.
1639 * doc/gdbint.texinfo: Add documentation on symbol-reading
1642 * mipsread.c: Remove kludges around #include "ecoff.h".
1643 Remove redefinitions of a_magic, etc, no longer used.
1644 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
1645 Fix global overview comments to match symfile.c protocol.
1646 (mipscoff_new_init): Eliminate cur_hdr if we have one.
1647 (mipscoff_symfile_read): Eliminate unused code. Avoid
1648 sorting all the symtabs, when all we have read here is psymtabs.
1649 The symtabs are sorted as they are created anyway. Tell
1650 condense_misc_bunches whether we're mainline.
1651 (psymtab_to_symtab_1): Pass filename when recursing, to make
1652 stack trace more informative.
1653 (parse_partial_symbols): Assume cur_hdr as argument.
1654 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
1655 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
1656 the TYPE_NAME of char *, since that's done in symfile.c.
1657 (free_numargs, parse_symbol, add_symbol, add_block,
1658 shrink_linetable): Declare these fns void.
1659 (upgrade_type): Convert tree of if's to switch. Clean up
1660 bogus "off == 0" handling with a complaint. Avoid setting
1661 field bitpos and bitsize of array with lower and upper bounds.
1662 Check specified bitsize of elements against their actual type's
1663 bitsize, and complain if different. Complain about unknown
1665 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
1666 (psymtab_to_symtab_1): Print names of subsidiary files that
1667 are being read in. FIXME, we read far too many files. This code
1668 is not the problem, the problem is in parse_fdr where the psymtabs
1670 (cross_ref): Result should indicate that we used one aux entry
1671 normally, or two if we encountered a "next" entry. This used
1672 to leave the caller pointing at the wrong aux entry.
1673 (add_symbol): If overflowed cur_block, reallocate it larger,
1674 chase all pointers to it, and complain(), rather than clobber memory.
1675 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
1676 (new_field): Only allocate one field initially, not two.
1677 Pull ++ out of macro argument. Simplify.
1678 (_initialize_mipsread): Avoid initialization of importd
1679 global_psymbols and static_psymbols.
1681 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
1682 to properly set pst->symtab; avoid searching for it.
1683 (symfile_fns): Improve comments, add a FIXME.
1684 * dbxread.c: Update comments to reflect symfile protocol.
1685 (read_ofile_symtab, end_symtab): Return the symtab.
1686 (psymtab_to_symtab_1): Set pst->symtab.
1688 * coffread.c (coff_symfile_read): tell condense_misc_bunches
1689 whether we're mainline.
1691 * symfile.h (sym_fns): Remove unused sym_discard member.
1692 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
1694 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
1695 the environment variable is not.
1696 * infcmd.c (finish_command): Use filtered printfs.
1697 * cplus-dem.c: Add struct tags to a few unnamed structs.
1698 * valops.c (value_coerce_array): Improve comments.
1699 * valprint.c (type_print_varspec_suffix): Print array size only
1700 if greater than zero.
1701 * m88k-tdep.c: Shift some lines left by one space, that had
1702 apparently been trashed at some point.
1703 * TODO: More things to do, a few got done.
1705 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1707 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
1708 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
1710 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
1711 * expread.y, findvar.c, symmisc.c: Ditto.
1712 * printcmd.c (address_info): Update printed forms of LOC_
1713 symbols. Elim LOC_EXTERNAL.
1714 (print_frame_args): Keep track of param stack offsets before
1715 re-looking up to find the local register param is kept in.
1717 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
1718 Further integration of mipsread into gdb. Eliminate unused
1719 routines, duplicate declarations. Handle static symbols in
1720 psymtabs as well as external symbols. When reading symtabs,
1721 insert symbols into the correct block (global, static, or a local
1723 (read_mips_symtab, parse_partial_symbols): Don't pass useless
1725 (mipscoff_symfile_read): Don't call select_source_symtab.
1726 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
1727 rather than SYMBOL_VALUE.
1728 (parse_external): Comment clobbering of top_stack.
1729 (parse_partial_symbols): Update comments. Allocate and parse
1730 static symbols as well as external symbols. FIXME, enum values
1731 are not handled in this pass, but should be. Inline new_psymbol.
1732 Use SYMBOL_VALUE_ADDRESS.
1733 (psymtab_to_symtab_1): Read symbols into global static block
1734 by default (until enter some function's local block context).
1735 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
1736 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
1738 * source.c (select_source_symtab): Select a source symtab
1739 from either the symtabs or, failing that, the psymtabs.
1740 (list_command): Update error message.
1741 (forward_search_command, reverse_search_command): Use getc, not
1742 fgetc, for speed. FIXME, add comment about buffers that die if
1743 overrun by long line.
1745 * values.c (unpack_field_as_long, modify_field): Avoid shifting
1746 by an entire word, which is not portable, if we have a 32-bit
1747 field. (Code in dbxread.c already turns such bitfields, if
1748 aligned, into ordinary ints, but fixing this will help for other
1749 symbol formats and for future changes.)
1750 * core.c (core_open): Handle ANSI const brain death.
1751 * utils.c (vprintf): Fix varargs typo.
1753 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1755 * findvar.c (find_var_value): Handle &function better.
1756 * TODO: Document work needed on &fn and &array.
1757 * printcmd.c (print_address_symbolic): New arg is the prefix
1758 to print if a name is printed.
1759 (print_address_demangle): Honor "set print address" now.
1760 Use new arg above to improve spacing of output.
1761 * valprint.c (val_print): When printing function pointers,
1762 print symbolic form too.
1763 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
1765 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1767 * core.c (memory_error): Reword error msg to mislead less.
1769 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
1771 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
1772 parse_partial_symbols): Use newer BFD internals (external_filehdr
1773 and external_aouthdr), byte-swap the fields that we care about
1774 before using them, and make the file header data local to
1775 read_the_mips_symtab rather than global.
1777 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
1779 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
1780 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
1782 * main.c (command_line_input): Flush stdout and stderr
1783 before every call to readline. This reportedly fixes a bug
1784 that comes up in Sys V running emacs-gdb and/or xxgdb,
1785 when stdin/out are pipes or sockets.
1787 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1789 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
1790 Avoid declaring Makefile dependencies, because GNU Make stupidly
1791 tries to update it if we do.
1793 * coffread.c: Revise for minor changes to bfd internal coff
1796 * configure: If -template= is given a relative path, make it
1797 absolute before recurring in subdirectories.
1799 * configure, configure.in, Makefile.in: Install "configure" script
1800 as replacement for config.gdb.
1801 * config.gdb, Makefile.dist, Makefile.sdir: Remove
1802 * README: Update for configure, mostly. FIXME.
1804 * Add dec3100 as equivalent to littlemips. Indicate in all host &
1805 target config files that they are for the host. When the lines
1806 get copied into the Makefile, this makes it more obvious what's
1809 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1811 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
1812 tabs, which end up in the disassembler output inadvertently.
1814 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1816 Make it compile cleanly in an ANSI GCC2 environment.
1818 * blockframe.c: <stdio.h>
1819 * cplus-dem.c: free takes a void *, ifdef __STDC__
1820 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
1822 * defs.h (alloca): Avoid doing anything if alloca already def'd.
1823 * stddef.h, stdlib.h: Remove these files.
1824 * symtab.c: Avoid declaring qsort, close.
1825 * symfile.c: Avoid declaring close.
1826 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
1827 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
1829 Assorted other changes.
1830 * dbxread.c: include "libaout.h", not "liba.out.h".
1831 * printcmd.c (print_frame_args): Set recurse properly for
1832 indentation of struct and array parameters.
1833 * valops.c (value_cast): Allow cast to void.
1834 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
1835 single_step() in a target-independent fashion.
1836 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
1837 set up to be ready to continue. This makes us target independent.
1838 * infptrace.c (child_resume): Remove call to single_step; now
1839 can single step a SPARC target of any kind.
1841 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1843 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
1844 docn into separate sections---basically chapters, plus two loose
1845 pieces that can be configured to go in different places. This
1846 allows GNU m4 to preprocess the manual without coredumping.
1848 * Makefile.dist: tell TeX where to find texinfo.
1850 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1852 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
1853 the new target "rdl-apps.texinfo" which captures the Makefile
1854 variable that records where to find the Readline libraries.
1856 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
1858 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
1859 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
1860 * defs.h (const, volatile): Only define if not already defined.
1861 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
1863 * README: Update for release 3.95.
1864 * config.gdb: Don't create readline dir in subdir builds.
1865 * main.c: Include with "..." form for non-system include files,
1866 so "gcc -MM" for "make depend" works.
1867 Include readline files with "...h" rather than <readline/...h>.
1868 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
1870 * coffread.c: Undo minor damage done by Rich Pixley. Use
1871 different internal and external representations of COFF
1872 data structures. Use new BFD routines for swapping them in and
1874 * symfile.c (free_named_symtabs): Avoid freeing file names that
1875 are null or empty. Old i960 tools seem to produce files that
1876 claim to have empty names, causing each successive file read
1877 to blow away the previous one.
1878 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
1879 Move deferred_stores to top of file, but don't separate its
1880 #define's from its variable. Add commentary.
1881 * Makefile.dist: Fix Rich damage; undo "configure" changes in
1882 favor of keeping the (working) config.gdb. Move readline
1885 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
1887 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
1889 * infptrace.c (fetch_registers): no result, since now void.
1890 * tconfig/news: target depends on m68k-tdep too.
1892 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1894 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
1897 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
1898 applied various small fixes due to or inspired by RMS comments
1900 * doc/gdb.texinfo: finished using all RMS comments, save those for
1901 appendices on readline and cmd history (which are in other source
1904 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1906 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
1907 chapter 9; (2) documented 'break' command's menu mode for
1908 overloaded names, in response to hgs problem report C++ p-31
1910 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1912 * doc/gdb.texinfo: (1) better introductory example; (2) more
1913 consistent use of @code, @samp, @file, @kbd throughout; small
1914 cleanups to first three nodes; (3) new "Contributors" node;
1915 (4) Appendix, Renamed Commands; (5) divert specialized startup
1916 instructions to "Targets" chapter for generic manuals, while
1917 leaving them up front for manuals specific to specialized
1918 environments; (6) apply fixes from RMS comments through chapter 4.
1920 * pretex.m4: modify explanatory text slightly (and redefine
1921 "regexp") to keep GNU m4 from complaining. (It still crashes
1922 later, but one step at a time...)
1924 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
1926 * readline/readline.c (update_line): Avoid dereferencing a pointer
1927 before comparing it to its bounds. Saber caught this.
1928 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
1929 and only set PC if tgetstr returned non-null. Saber caught this.
1931 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1933 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
1934 stuff for config manual) here where it counts; updated
1935 to use new subdir structure (gdb/doc/).
1937 * Makefile: generated from above via
1941 * gdbint.texinfo: added instructions on generating gdb.info* files
1942 locally for release. These are ordinary info
1943 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
1944 Makefile)---but due to use of texinfo 2, can't count on makeinfo
1945 to generate these, so we distribute them already formatted.
1947 * gdb.texinfo: included full Info node and menu crud (as generated
1948 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
1950 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
1951 put in comments-for-future gdb.info target (one day makeinfo will
1954 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1956 * gdb.texinfo: Updated to include new or old undocumented
1957 commands, at least the following (perhaps some others I forgot to
1958 record): info f, info float, info path, info program, info s, info
1959 set, info source, info terminal, info types, info user, set/show
1961 Also covered all recent GDB command renames for v4.
1963 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1965 * mipsread.c: Rather than keeping count of how many symtabs
1966 and psymtabs we have, for sorting purposes, count them when
1967 we need to sort. This fixes bug in rereading of symbol tables.
1969 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1971 * infcmd.c: renamed "info path" to "show paths"
1972 * gdbrc.tex: documented above.
1974 Wed May 8 04:51:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1976 * remote.c: Fix comments.
1977 * utils.c (error): Force out any pending wrap output.
1979 Sat May 4 11:11:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1981 * Makefile.dist: Roll VERSION to 3.95.
1982 Fix up "saber_gdb" to work again.
1983 * saber.suppress: Update.
1985 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
1986 symtab.h, target.c, target.h: Lint.
1987 * core.c: setup and select frame after reading shared libs,

2455 Thu Apr 18 19:49:10 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
2457 * i386-pinsn.c (OP_E): Change %d to 0x%x for consistency.
2459 * putenv.c: New file
2460 Makefile.dist: Add it to $(OBS).
2462 * mipsread.c [!CMUCS]: #include <syms.h>.
2464 * mips-xdep.c (fetch_core_registers): #if 0 out the whole function.
2466 * Move read_memory_nobpt from mem-break.c to breakpoint.c.

2470 * utils.c (_initialize_utils): Rename "set demangle" to
2471 "set print demangle", "set asm-demangle" to "set print
2472 asm-demangle" and "set sevenbit-strings" to "set print

2493 Rename "set array-max" to "set print elements".
2494 Rename "set prettyprint" to "set print pretty".

2504 Sun Apr 14 23:08:34 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
2506 * inftarg.c (child_open), remote-vx{,.68}.c (vx_proc_open):
2507 New function to give correct error message.
2509 Thu Apr 11 17:19:41 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
2511 * target.h: Add to_doc and target_preopen.
2512 target.c: Add target_preopen and target_command.
2514 (add_target): Call add_cmd and mess with targetlist->doc.
2515 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
2516 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.
2517 Call target_preopen from open routine.
2519 * main.c: Rename editing_info to show_commands.
2520 (_initialize_main): Rename "info editing" to "show commands".
2522 * source.c: Rename directories_info to show_directories.
2523 (_initialize_values): Rename "info directories" to "show directories".

2534 Rename add-syms to add-symbol-file.
2536 Thu Apr 18 18:08:30 1991 John Gilmore (gnu at cygint.cygnus.com)
2538 * symfile.h (free_named_symtabs): Rename from free_named_symtab.
2539 * symfile.c (clear_symtab_users_once, cashier_psymtab,
2540 free_named_symtabs): Move these routines from symmisc.c.
2541 * symmisc.c (same): same.
2542 (free_symtab): Make non-static.
2543 * symtab.h (free_symtab): Declare as exported void fn now.
2544 * dbxread.c (end_symtab, end_psymtab): Change comments.
2545 (initialize_dbxread): Call dbx_new_init() in case the first
2546 command is add-symbols.
2547 * target.c (dummy_target): Permit add_syms_addr_command.
2549 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2551 Permit symbols to be superseded when new symbol files have
2552 been read in, particularly for VxWorks.
2554 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
2555 to the main file, as well as to include files. Also, put global
2556 functions into the global psymtab, to make "i fun" work.
2557 (end_psymtab): Free named symtabs and psymtabs for a file, once a
2558 new psymtab for it has been read.
2559 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
2560 a file, once a new symtab has been read for it.
2561 * mipsread.c: FIXME. We need to do the same for MIPS, but it
2562 looks harder to determine the top-level block before it's been
2563 queued to the psymtab list.
2565 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
2566 If we have wiped out any old symbol tables, clean up at end of
2568 (symbol_file_command): Don't reference symfile_fns if it's zero.
2570 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
2571 defines for the blocks of a blockvector that contain global and
2572 file-static symbols and the first of the smaller scope contours.
2573 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
2574 decode_line_1, make_symbol_completion_list): Use the above.
2575 * coffread.c (end_symtab, patch_opaque_types): Ditto.
2576 * dbxread.c (end_symtab): Ditto.
2577 * expread.y (block): Ditto.
2578 * mipsread.c (throughout): Ditto.
2579 * symmisc.c (free_named_symtabs): Ditto.
2581 * symtab.c (list_symbols): Process the first symbol of the
2582 static psymbols list.
2583 (types_info): Restore this function from its untimely #if 0.
2584 It's not perfect, but it is better than nothing.
2585 (_initialize_symtab): Restore "info types".
2587 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2589 * m68k-stub.c: Remote stub for 680x0's, created from
2590 rem-m68k.shar (which is removed).
2591 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
2592 Remove RCS log stuff now that we use CVS and it blows our diffs.
2594 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2596 * symmisc.c (free_named_symtab): Make it work, in its current
2597 kludgy fashion. Change result to indicate if we blew away bkpts.
2598 * dbxread.c (end_symtab): Accumulate result from
2599 free_named_symtab and print warning if we blew user's state.
2600 * symfile.h: free_named_symtab now returns an int.
2602 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
2604 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
2605 is the first symbol read, even if not mainline.
2606 (dbx_psymtab_to_symtab): symfile might be zero, cope.
2607 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
2608 (set_section_command): New command ("section xxx yyy" -- should
2609 be renamed to "set section xxx yyy" FIXME) which sets the
2610 base address of a section of the exec file, overriding the
2611 virtual address that BFD reports.
2613 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2615 * exec.c: Add add_syms_addr_command to exec_ops, so you can
2616 load symbols at any address while examining an exec file.
2618 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2620 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
2621 for printing the float info is host-dependent, not
2622 target-dependent. FIXME.
2623 * i386-pinsn.c: Move #includes to top, remove useless ones.
2624 * i386-tdep.c: Don't bother including <.../reg.h> since we
2625 don't use it (and it doesn't exist on host systems).
2627 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
2628 Convert negative numbers properly.
2629 (ieee_test): Make numbers really random; fix format arg.
2631 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
2632 * core.c (core_detach): Unpush core_ops, which might not be on
2633 top. We used to just pop the top, which broke things. Don't
2634 need dont_repeat() any more.
2635 (core_file_command): Psst! Don't repeat it.
2636 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
2637 * expprint.c (print_subexp): Avoid switch fallthru on
2638 BINOP_ASSIGN_MODIFY, so we can print += and such.
2639 * frame.h: Fix typo.
2640 * inflow.c (kill_command): After killing inferior, print our
2641 current frame in the core file, if we have one.
2642 (generic_mourn_inferior): When inferior dies, either select
2643 the current frame (in the new target, e.g. core file), or
2644 set both the current and selected frames to NULL.
2646 Changes from Peter Schauer.
2648 * infptrace.c: Avoid <sys/ptrace.h> on USG.
2650 * Make all file names fit in 14 characters (sigh and damn!):
2651 mv hp300hpux-xdep.c hp300ux-xdep.c
2652 mv symmetry-xdep.c symm-xdep.c
2653 mv symmetry-tdep.c symm-tdep.c
2654 mv convex-opcode.h convx-opcode.h
2655 mv tm-vxworks960.h tm-vx960.h
2656 mv tm-vxworks68.h tm-vx68.h
2657 mv Makefile.srcdir Makefile.sdir
2658 mv gdb-int.texinfo gdbint.texinfo
2659 mv remote-sa.m68k.shar rem-m68k.shar
2660 mv remote-multi.shar rem-multi.shar
2661 * Makefile.dist, README, config.gdb, convex-pinsn.c,
2662 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
2663 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
2666 * command.c (user_info_1, user_info): New command for listing
2667 the user-defined commands.
2669 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2671 * dbxread.c (really_free_pendings): Clear file_symbols
2672 and global_symbols after freeing them; otherwise, running
2673 this function twice (if it appears twice on the cleanup
2674 chain), we try to free things twice.
2676 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
2677 based on text_addr (the address of text in core), not on addr (the
2678 offset between text in the .o file and in core). This change
2679 is from Peter Schauer.
2681 * main.c: Define ALL_CLEANUPS as a cast of zero.
2682 (return_to_top_level): Use it.
2683 (main): Do all cleanups after each command run as part
2684 of the gdb startup sequence. Also do all cleanups before
2685 entering the command loop, and every time we exit the command
2686 loop and reenter. Before, the cleanups from the startup sequence
2687 were being left undone until the first error!
2688 (command_loop): Rename do_nothing cleanup to command_loop_marker
2689 so we can see it easily when examining the cleanup chain.
2690 (init_signals): Add another do_nothing for signal handling.
2691 (quit_command): Only try to kill target if it has execution.
2692 Problems in the target stack got us into a state where
2693 inferior_pid was nonzero but none of the targets had execution.
2694 In this state you couldn't exit gdb.
2696 * dbxread.c: Two changes from Peter Schauer.
2697 (echo_command): Fflush output after an echo command.
2698 (show_history): Pass all args to cmd_show_list.
2700 * utils.c (init_malloc): Call mtrace to turn on tracing
2701 if the environment variable MALLOC_TRACE is set to a file name.
2702 * mtrace.c: Add source file which provides a log of every malloc,
2703 free, and realloc to a trace file.
2704 * mtrace.awk: Add source file which analyzes the trace file.
2705 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
2706 (VERSION): Roll to 3.94.3.
2708 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
2709 (check_duplicates): Don't bother with watchpoints.
2710 (set_raw_breakpoint): Comment about danger of this routine.
2711 (watch_command): Parse and eval all args before calling
2714 * solib.c (find_solib): Avoid error in referencing memory to
2715 see if any more shared libraries have been added. This is
2716 particularly useful if the target has terminated. Bug reported
2719 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
2720 in bringing up 3.94.2 on the Sun-3.
2722 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
2723 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
2724 expression (in scope) before reenabling watchpoint.
2725 * signame.c (init_sigs): Add missing declaration of i, fix
2726 sys_siglist declaration.
2727 * source.c (list_command): Fixed range computation to use
2729 * stack.c (backtrace_command): Do not allow command if target has
2730 no stack, print informative error message.
2731 * target.c (target_command): Do not write into command line
2732 because this fails if the target command is used in a user defined
2733 command. [This change was enhanced by gnu to support any-
2734 unique-prefix matching on target names.]
2735 * valops.c (value_struct_elt): Avoid infinite loop on an
2736 erroneous attempt to print the member of function (try p main.p).
2738 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2740 * expread.y (name_no_typename): Avoid reduce/reduce errors
2741 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
2742 Since the GDB parser really doesn't use name_no_typename in a
2743 name-only context, the parser can't tell the diff between
2744 names and numbers here. Avoid allowing a name_no_typename
2745 to be a NAME_OR_*INT to resolve the conflict.
2747 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2749 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
2751 * valprint.c (val_print_fields): bitfield printing didn't handle
2752 byte order. Indirect through a few more fns to cope.
2754 * values.c (modify_field): also cope with byte order.
2756 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2758 Cleanup for release 3.94.2:
2760 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
2761 include files. Roll version to 3.94.2.
2763 * coffread.c (init_stringtab): Read length into unsigned char
2764 array before swapping; don't assume 32-bit longs.
2766 * target.c (target_info): Don't bother with get_sym_file, just use
2767 the symfile global variable.
2768 * symtab.h, symfile.c (get_sym_file): Delete it.
2770 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
2771 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
2772 (read_type): Replace one more error() with complain().
2774 * mipsread.c (parse_partial_symbols): Replace printf with complain.
2776 * i960-tdep.c: Fix copyright attribution.
2778 * config.gdb: Quote all backquotes in doublequotes. You can
2779 quote me on that. BSD 4.4 shell found this one.
2781 * infptrace.c (throughout): The third argument to ptrace is an
2784 * infrun.c (wait_for_inferior): When program has terminated, we
2785 have to call target_terminal_ours before we pop that target off
2786 the stack (e.g. before a call to target_kill or
2787 target_mourn_inferior). This fixes problem where a program
2788 terminates, then GDB stops for (tty output) and you have to type
2789 "fg" to the shell to resume it. FIXME: This code for what to
2790 do after termination really should be in normal_stop instead.
2792 * gdbcore.h (read_memory_check): Change declaration; it changed
2795 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
2796 4.4 prereleases, this avoids a bug in their sgtty compatability
2798 * remote.c: Use terminal.h rather than hand-rolling the same.
2800 * signame.c, signame.h (psignal): Arg is unsigned, not int.
2801 * utils.c (strsave, strstr): Fix arg types.
2802 * valprint.c (val_print): lint
2804 MIPS symbol table support from Per Bothner:
2806 * symfile.c (symtab_fns): Remove initializer table that needs to
2807 be hacked for each new symbol file format supported.
2808 (add_symtab_fns): New function, chains symbol table
2809 handlers into the global list.
2810 (symfile_init): Search this list.
2811 * symfile.h: Add next pointer, declare add_symtab_fns.
2812 * coffread.c (_initialize_coffread): Call add_symtab_fns.
2813 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
2815 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
2816 symbol *). Thus, we no longer need the hack to trash
2817 pst->filename. Good, since that hack confused code in symfile.c!
2819 (reorder_symtabs, destroy_all_symtabs): Removed static
2820 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
2821 Instead, the latter now uses a temporary array (stack-allocated
2822 from an obstack, and then freed).
2824 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
2825 haven't been set in the outermost stBlock of a procedure. This was
2826 a problem with f77 binaries on Ultrix 4.?.
2828 (new_symtab, new_symbol, new_type): Continue changing code to use
2829 obstacks more and otherwise conform to dbxread internal style.
2830 Made the free_code of symtabs be free_linetable (as in dbxread)
2831 instead of free_contents. This implies memory leaks when reading
2832 a new symbol table, until the conversion is finished. Did change
2833 (struct symbol) and (struct type) to be allocated on the
2834 symbol_obstack. Blocks and blockvectors are among the things
2837 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
2838 tested much, but it solved one problem (reported by Meissner), and
2839 cleans up some other things. The problem happened when an
2840 included file contains actual code (functions) and not just
2841 definitions. The mips coff is a little inconvenient there, since
2842 it may cause a procedure to be mapped to the wrong psymtab.
2844 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
2845 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
2846 this will need work for the new core paradigm.
2848 Opcode patches from the net:
2850 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
2851 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
2852 missing altogether - they are added here. From Bruce Bauman.
2853 * mips-opcode.h: The low mask for C0 instructions was too small.
2854 From Garrett Lau. I modified the fix to check the entire 32-bit
2857 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
2860 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2862 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
2864 * dbxread.c (read_type): Pointer subtraction (value_sub in
2865 valarith.c) sometimes failed because the types of the
2866 pointers being subtracted were not identical.
2867 These differed because dbxread.c was allocating pointer types
2868 using dbx_alloc_type+smash_to_pointer_type instead of
2869 lookup_pointer_type. I failed to find a justification for the
2870 former, so I changed it to use the latter. Similarly, I
2871 replaced smash_to_function_type by lookup_function_type,
2872 and smash_to_reference_type by lookup_reference_type.
2874 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
2875 _initialize_mipsread): corresponding changes.
2877 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
2879 * source.c (mod_path): Do tilde_expand on each component of the path,
2880 rather than on the (list of) paths as a whole.
2881 (print_source_lines): Set first_line_listed in addition to
2882 current_source_symtab and current_source_line. If the source was
2883 not findable, after a "dir" command to fix the problem,
2884 a "list" would get the wrong lines.
2886 While I was there... (gnu):
2888 * dbxread.c (read_type): Change error to complaint.
2890 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2892 First attempt at detailed understanding of symbol table memory alloc.
2894 * dbxread.c (dbx_symfile_read): Free our string table if we
2895 aren't the mainline. Free the "info" struct since we're done with
2897 (init_psymbol_list): Free any previously allocated psymbol lists.
2898 (): FIXME: Should realloc-down the psymbol lists when done reading
2899 the main symbol file?
2901 * symmisc.c (free_symtab): Free fullname field too.
2903 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
2904 (REGISTER_ADDR): Make result type unsigned int.
2906 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
2907 define REGEX must also define REGEX1 (its dependency).
2909 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2911 * tconfig/i960: No longer works, points you at vxworks960 or
2914 * xgdb.c, XGDB-README: Remove file. Users can get the much
2916 * Makefile.dist: Remove all trace of xgdb.
2918 * breakpoint.c (breakpoint_1): Pass demangle arg to
2919 print_address_symbolic.
2920 (clear_breakpoints): Remove unused function.
2921 (breakpoint_re_set_one): Guts of breakpoint_re_set.
2922 (breakpoint_re_set): Use catch_errors to do them all anyway.
2924 * gdb-int.texinfo (Host versus Target): Add section on what is
2925 a "host" feature versus what is a "target" feature.
2927 * infcmd.c (path_command, path_info): Handle the PATH variable
2928 (object search path) as conveniently as the source search path.
2929 * environ.c (set_in_environ): Set some vars in GDB's environment,
2930 in addition to the child's. PATH, G960BASE, G960BIN for starters.
2931 * source.c (mod_path): New function, from guts of

2941 "set screen-height" => "set height"; add sevenbit-strings.
2943 * infcmd.c (do_registers_info): Print floating point registers
2944 in raw hex as well as float format, regardless of whether it is
2945 a "virtual" convertible register.
2946 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
2947 regs as a double, just in case it's being used that way.
2948 * values.c (unpack_long): Comment on array/function coercion.
2949 (unpack_double): Argument is in target byte order now. For
2950 integer arguments, just call unpack_long and float the result.
2951 * m68k-tdep.c: include defs.h for "const" handling.
2952 * remote-nindy.c: Use ieee-float stuff.
2953 (nindy_fetch_registers): Unpack double regs to host double, then
2955 (nindy_store_registers): Pack extendeds to host double, flip
2956 around by misusing unpack_double, send as target double.

2967 Changes from a bringup on the DEC Vax under Ultrix 4.0.
2969 * coredep.c (fetch_core_registers): Pass end-address of register
2970 section to register_addr as expected. Don't call supply_register
2971 if we'd just pass it garbage.
2973 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
2975 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.

3008 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3009 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3010 * tconfig/nindy960: Remove reference to coffstrip.o.
3012 * Makefile.dist: Roll version number to 3.94.1 (not yet final).

3020 * inftarg.c (child_detach): Pop the child_ops vector if the
3021 detach is successful.
3022 * remote-nindy.c (nindy_create_inferior): Don't push a new
3023 nindy_ops since nindy uses the same one for execution and memory
3025 * core.c (core_ops): Use child_attach and child_create_inferior
3026 rather than default attach and create_inferior functions.
3028 Handle floating point registers in core files.
3030 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3031 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3032 This version untested since BFD doesn't yet support sun3 core
3034 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3035 conventions. Fix comments and style. This version has not
3036 been compiled yet, since we have no HP inhouse.
3037 * core.c (get_core_registers): Look for two sections, ".reg"
3038 and ".reg2", and pass both to fetch_core_registers sequentially.
3040 Revise directory path yet again.
3042 * source.c (forget_cached_source_info): Not static any more.
3043 (init_source_path): New default source path is "$cdir:$cwd".
3044 (dir_command): Handle variable arguments ($cdir, $cwd).
3045 (source_info): Print "Compilation directory" rather than
3046 "Originally compiled in" to remind people of $cdir.
3047 (openp): If the path contains $cwd, use current directory.
3048 (open_source_file): If compilation directory is known, replace
3049 first $cdir in path with the compilation directory.
3050 (print_source_lines): Even if we can't print the lines, set the
3051 current symtab and line for future commands like "info source" or
3052 "breakpoint". Also, error message now contains the file name,
3053 line number, and file access error message.
3054 (_initialize_source): Fix help text to describe changes.
3055 * main.c (cd_command): Forget cached source info when we chdir.

3061 Byte-swap COFF symbol tables if necessary when reading them in.
3062 Use complain() to replace error message in one spot. Needs
3063 corresponding change in bfd/coff-code.h to make some symbol
3064 swapping routines non-static.
3066 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3068 Merge changes from Eirik Fuller, for UTek.

3076 declarations of errno.
3078 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3080 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3081 <rpc/rpc.h> and <rpc/types.h>.
3083 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3085 * i960-tdep.c (examine_prologue): Add new argument limit,
3086 which stops the scan at the end of the prologue, or at the PC.
3087 This fixes a problem where it walks down into the code for the
3088 user's statements if that code looks like function prologues.
3089 Mark Fox and I have been bouncing this code back and forth, making
3090 small changes to it. Callers changed to match.
3092 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3094 Cleanup for gdb-3.94 release final:
3096 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3097 the .c files from vx-share and nindy-share, from the various
3098 macros, since they are not found via ALLDEPFILES.
3099 (SFILES): Add tm-i960.h.
3100 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3101 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3103 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3104 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.

3108 * am29k-tdep.c: Add contribution line.
3109 (examine_prologue): Cache information about function prologues in
3110 the misc-function-vector to avoid lots of references over the
3111 serial line while examining instructions.
3113 * core.c (core_close): New function made from cleanup_core.
3115 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3116 remote-vx.c, remote.c, target.c, target.h,
3117 Update target_ops vector to add attach, close, and load entries.
3118 Use add_syms_addr_command, not add_file_addr_command, for
3119 add_file. Break out close routine from existing code.
3121 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3122 they are in an obstack.
3123 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3125 (define_symbol): Add symbol type parameter; change callers;
3126 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3127 it to influence the symbol class on the i960.
3128 (define_symbol): Swap LOC_CONST's into target byte order.
3130 * exec.c (exec_close): New function.
3131 (exec_file_command): Call it.
3133 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3134 Fix byte order of frame pointer.
3135 (read_var_value): Result of 0 if var's value can't be found,
3136 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3137 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3138 (locate_var_value): Use read_var_value and use its lazy address
3139 as the location of the var's value. Lint.
3141 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3144 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3145 obsolete Intel versions in favor of vxgdb versions.
3146 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3147 code dealing with byte order of values, which Intel did in host byte
3148 order rather than gdb-4's target byte order.
3149 (i960_frame_chain_valid): Move to nindy-tdep.c.
3150 (examine_prologue, skip_prologue, frame_find_saved_regs,
3151 frame_args_address, leafproc_return, saved_pc_after_call,
3152 pop_frame): Add vxgdb versions from Mark Fox.
3153 (examine_prologue, frame_struct_result_address): Add code
3154 to deal with the saved value of G13 (struct return address
3156 (frame_args_address): Modify Mark's version to prefer the
3157 saved value over the current value in the topmost frame.
3158 Cache result in the frame info to avoid performance hair in
3160 (print_fault): Add gdb960 code for printing faults.
3161 (_initialize_i960): Actually call check_host.
3163 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3164 add stub routines. FIXME, these currently just return zero!
3166 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3167 (attach_command): Call target_attach, not target_open, now.
3169 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3170 (child_attach): Rename from child_open.
3171 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3172 don't confuse it with a zero step_resume_break_address.
3174 * inftarg.c (child_detach): Eliminate inferior_pid test.
3175 (child_files_info): Clean up message a bit.
3176 (child_ops): Use child_attach, not child_open, to attach.
3178 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3179 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3180 findvar.c to here, since it depends on the contents of the
3181 shadow_contents of breakpoints, but keep if #if 0 since it is
3184 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3187 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3188 (ptype_command, display_command): Eliminate have_inferior_p and
3189 have_core_file_p in favor of target_has_stack or
3190 target_has_execution.
3191 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3192 code for actually finding the values of arguments, though we still
3193 keep track of the maximum stack offset for use in printing unnamed
3194 arguments. Handle missing FRAME_ARGS_ADDRESS.
3196 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3197 (struct nindy_regs): Define registers passed to/from nindy.
3198 (nindy_fetch_registers, nindy_store-registers): Translate between
3199 nindy and GDB formats for the registers.
3200 (dcache_init): Statically allocate the cache, since it was being
3201 allocated by a malloc that was never freed anyway.
3202 (nindy_create_inferior): Error, not core dump, if no exec file.
3203 (nindy_before_main_loop): Use target_load, not target_add_file.
3205 * remote-vx.c (net_load): Specify large timeout for load
3206 requests. Allow user to break out with INTERRUPT.
3207 (net_break): Remove useless code, clean up. Change callers.
3208 (parse-args, skip_white_space, find_white_space): Clean up arg
3209 parsing to cope with quoted strings.
3210 (net_wait, net_quit): Never call error, just return status.
3211 (vx_read_register, vx_write_register): Cleanup status checking.
3212 #ifdef the code based on which CPU we are using (960 or 68k),
3213 FIXME, this should be completely general but it isn't yet.
3214 (vx_xfer_memory, vx_resume): Cleanup status checking.
3215 (vx_run_files_info): Improve message.
3216 (vx_load_command): Renamed from vx_add_file_command. Allow load
3218 (net_ptrace): Remove unused routine.
3219 (vx_wait): Adopt code from vxgdb960 to cope with broken
3220 connections to target machine and prompt to disconnect. Remove
3221 debug printouts. Map some EVENT_'s to SIGnals.
3222 (add_symbol_stub, vx_open): Print names of object files we found,
3223 and "ok" if we read their symbols OK. Clarify output in general.
3224 (vx_attach, vx_detach, vx_kill): Add these commands.
3225 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3226 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3227 "info files" output, and create_inferior, since we already have
3230 * stack.c (frame_info): Replace Frame_unknown with 0.
3231 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3232 (return_command): Pop until the PC matches as well as the FP,
3233 so it works even if the FP is shared with another function,
3234 as in "frameless" or "leaf" procedures.
3236 * symfile.c (load_command): renamed from add_file_target_command.
3237 (add_syms_addr_command): renamed from add_file_addr_command.
3238 (add_syms_command): Stub to call target_add_syms.
3239 (_initialize_symfile): Change command names and descriptions,
3240 add-file => add-syms, and load from alias to its own command.
3242 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3243 maybe_kill_then_create_inferior): Default for attempts to start
3244 a process, if one is already running, is to ask about killing
3245 it and retry if yes.
3246 (upstack_create_inferior): #if-0 it, strata obsolete it.
3247 (push_target, unpush_target, pop_target): to_close() a target
3248 before unstacking it.
3249 (target_info): Renamed from target_files_info.
3250 (_initialize_targets): Rename "i files" as "i target", accessible
3253 * target.h: Improve comments about the target_ vectored routines.
3255 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3256 Convert commenting style to standard GNU style.
3257 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3258 (SKIP_PROLOGUE): No longer a no-op.
3259 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3260 (*_REGNUM): Sort register numbers.
3261 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3262 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3263 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3264 are now 10 byte extendeds, not 8 byte doubles.
3265 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3266 for nindy versus vxworks targets. FIXME, this should possibly go
3267 in the target vector.
3268 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3269 frame_saved_regs and arg pointer with each frame.
3270 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3271 (FRAME_ARGS_ADDRESS): Use cached result.
3272 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3273 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3274 (PRINT_RAMDON_SIGNAL): Call print_fault.
3275 (POP_FRAME): Now works.
3277 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3278 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3279 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3280 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3283 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3284 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3286 * valarith.c (value_subscripted_rvalue): Avoid handling
3287 floats and doubles specially; it gave alignment errors. Lint.
3289 * valops.c (value_of_variable, value_of_this): Error if unknown
3292 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3293 to avoid alignment problems.
3294 (value_print): Handle unknown value address.
3295 (cplus_val_print): Two args are ignored; remove them. Change caller.
3296 (val_print): Use unpack_long rather than pointer-deref.
3299 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3300 to avoid alignment problems.
3301 (value_being_returned): Error if return value unknown.
3302 (set_return_value): Add bogosity warning, FIXME. *
3304 * TODO: A woman's work is never done.
3306 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3307 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3308 Add ieee-float.o to OBS.
3309 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3310 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3311 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3313 Changes to generalize the VxWorks RPC protocol slightly, to handle
3314 i960 as well as 68000.
3316 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3317 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3318 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3319 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3320 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3321 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3322 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3323 so they will move in target byte order rather than network
3324 byte order (happens to be the same).
3326 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3328 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3330 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3333 Add contribution lines to various files, showing where they
3336 * breakpoint.c (break_insn, check_break_insn_size,
3337 read_memory_nobpt): Remove to mem-break.c.
3339 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3342 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3343 entry has bad register number. This change is not
3344 tested in this release, FIXME.
3346 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3349 * value.h: Force value's contents field to be aligned to hold
3350 at least a double or a long long (if supported). This avoids
3351 doing bcopy's in and out of the contents field.
3353 (step_1): Avoid coredump under obscure circumstances when we
3356 * symtab.h (misc_info): Add field to misc function vector for
3357 any kind of cached information the target code desires. AMD
3358 29000 uses this to avoid repeating examine_function_prologue's.
3360 * coffread.c: Lint. Remove static symfile, read_section_header.
3361 core.c (have_core_file_p): Lint: remove.
3362 expprint.c (print_subexp): Lint.
3363 infptrace.c, valops.c, valprint.c: lint.
3365 Roll in changes from vxgdb-5.0.1:
3367 * symtab.h: Comment byte order of each address class. Add
3368 LOC_LOCAL_ARG for frame-relative args (960).
3369 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3370 symtab.c, symmisc.c: ditto.
3372 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3374 * remote.c (remote_resume): Error if resume with a signal.
3376 * symfile.c (prim_record_misc_function): Clear misc_info.
3377 (fill_in_vptr_fieldno): Check stub type of arg.
3379 * valops.c (value_cast): Avoid looking up names of types whose
3380 name we don't know, to prevent coredump. Sun CC produces typedef
3381 rtx and the name of *rtx is zero...
3383 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3385 Roll in changes from final AMD 29000 port (Tiemann).
3387 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3388 for ../include/a.out.encap.h. This might not work now that BFD
3389 is separately compiled. Instead, BFD support for encap will have
3390 to translate machine type 29k into the right COFF_MAGIC.
3392 * infcmd.c: Remove references to inferior_pid that aren't used
3393 in actual ptrace calls; use target_has_execution, etc.
3394 (have_inferior_p): Remove function.
3395 (program_info): Print target info rather than "process number";
3396 avoid gratuitous messages unless from_tty.
3397 (run_stack_dummy, finish_command): Set proceed_to_finish.
3398 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3399 main.c: Lint. Lose have_inferior_p().
3400 inferior.h (have_inferior_p): Remove, lint.
3401 (proceed_to_finish): Add flag to ask that all regs be saved
3402 by normal_stop, for the few commands that need it, speeding up
3403 serial I/O. Add comments to stop_registers.
3405 * remote-eb.c: Remove newline from breakpoint message we grep
3406 for. Never time out when running the user program.
3410 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3412 Roll in changes from vxgdb-5.0.1:
3414 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3415 symbol in its raw form, we are processing an unlinked ".o" file.
3416 See if the target environment has assigned it an address, using
3417 target_lookup_symbol (VxWorks does), and enter it into the symtab
3420 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3421 68k versions for a simpler version that assumes zero FP at bottom.
3422 Fixes bug of truncated stack reports.
3424 * target.h (target_lookup_symbol): Define this routine's args
3425 and result, finally.
3427 * target.c (nosymbol): Default routine for target_lookup_symbol.
3428 (target_default): Default lookup_symbol and call_function too.
3429 (files_info): Only print has_all_memory warning if a non-dummy
3432 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3433 vx_convert_from_virtual): If target does not have floating point,
3434 zero register "values", and avoid doing cross-net conversions.
3435 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3436 (vx_open): Rearrange code that attaches to target and reads
3437 symbols for all loaded modules, to work if some of the modules
3438 are not accessible. Add symbol_stub() and add_symbol_stub()
3439 as callbacks from catch_errors(). Allow connect attempt to be
3440 interrupted painlessly with ^C (FIXME, there are still some bugs
3441 if the interrupt happens during symbol reading.). Print
3442 final message with puts_filtered, since symbol messages are
3447 * main.c (catch_errors): Only print errstring if non-null.
3448 (command_loop): Avoid an ioctl per command to test ISATTY.
3450 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3451 (vx_xfer_memory): Return correct result!
3452 (vx_files_info): Indicate whether target has float or not.
3453 (vx_lookup_symbol): Complain, not error, if target gone.
3454 (vx_open): Print "Connected" msg before disabling immediate-quit.
3455 [FIXME: lookup_symbol and vx_open changes need testing.]
3457 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3458 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3459 contributor lines and update copyrights to 1991.
3461 Changes from an attempted H-PUX host port:
3463 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3464 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3465 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3466 * remote-vx.c: include <sys/time.h> for HPUX.
3467 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3468 "core_file_command" routine to BFD regime. May not work yet.
3470 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3472 * xgdb.c: Replace X10 version with some VJ version.
3473 (FIXME: Its copyright assignment is not on record.)
3474 * xgdb.c: Update include files to X11R4 (Xaw crud).
3475 (xgdb_display_source, create_text_widget): fix call to
3476 get_filename_and_charpos. Rewack source window stuff for X11R4
3477 (gleaned from include files, and "nm's" of binary libraries, since
3478 I had no doc available).
3479 (append_selection, append_selection_word): Disable with FIXME
3480 since R4 changed interface here.
3481 (create_buttons): Add back the old set of buttons.
3482 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3484 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3485 Roll VERSION to 3.94 (not yet final though).
3487 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3489 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3490 obstack_int_grow, obstack_int_grow_fast): Eliminate
3491 cast on left of assignment, which gives MIPS cc fits and is
3494 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3495 F_ALIAS. Use printf, not fprintf, when not passing a file
3497 (compare_opcodes): Check that identical instructions have
3498 identical opcodes, complain otherwise.
3500 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3501 was reported by Roland McGrath.
3502 (unimp): Only match if exactly zero instruction. (Roland)
3503 (branches and traps): Generate all variations of these
3504 instructions with macros, based on a single call that defines
3505 each condition name and its binary representation.
3506 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3508 * valprint.c (val_print_fields): Take, and use, format parameter.
3509 This means that "p/x struct" again prints the elements in the
3510 desired format. Changed callers.
3512 * stack.c (frame_info): Use filtered output, and indicate wrap
3513 points. Remove kludgy formatting designed to avoid line wrap.
3515 * utils.c (wrap_here): If the line is already full (because
3516 we had printed a long indent or long wrapped string), do an
3517 immediate newline-and-indent.
3519 * m68k-pinsn.c (print_insn_arg): Bugfix from
3520 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3521 instruction is incorrectly disassembled as bkpt #8.
3523 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3524 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3525 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3526 and then will dump core (sometimes). I traced it back to an
3527 uninitialized symfile_name in psymtab_to_symtab.
3528 (const_vol_complaint): Add quotes to message.
3529 (define_symbol): Only believe line number if gcc_compiled.
3530 Avoid allocating symbol if we will not return it.
3532 Add target strata support so that newly established targets go
3533 into their right place in the target stack (e.g. a new exec file
3534 doesn't wipe out the ability to access the running process).
3536 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3537 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3538 and initialize it properly in all the targets.
3540 * target.h: Document strata. Change return type of push_target.
3542 * target.c (nomemory): new function for dummy memory access.
3543 (tcomplain): Rename complain, now also used in symfile.c.
3544 (push_target): Push targets within strata. New return value shows
3545 whether new target is on top of stack or not. Always keep dummy
3547 (target_files_info): Ignore dummy target.
3549 * core.c (core_open): Warn user, and skip accessing file, if the
3550 core target is not the topmost target in the stack.
3551 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3554 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3555 target_ops, it doesn't belong there since we have no regs there.
3556 Change name of target from machine => memory to clarify.
3558 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3560 * Freeze version 3.93 for release.
3562 * Makefile.dist: Handle vx-share and nindy-share subdirs
3563 properly when building gdb.tar.Z.
3565 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3566 printed in various places, so I could change just one copy.
3568 * dbxread.c, coffread.c: Change references to bfd->iostream
3569 to cast to FILE *, now that BFD avoids needing types defined
3570 in other header files.
3572 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3574 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3575 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3576 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3577 (actually gcc -Wall).
3579 * dbxread.c: Remove first_global_sym, last_global_sym, since
3580 they are never referenced.
3582 * defs.h (baud_rate): Declare.
3583 main.c: Define it, and add the -b option to set it.
3585 * gdb-int.texinfo: Add text on how to define a new host or target
3586 architecture, prompted by Per Bothner's questions about MIPS
3589 * gdb.texinfo: Document "complaints". Change doc of -q since
3590 gdb no longer prints the copyright and blurb if you specify a file
3591 name to be debugged (just like Emacs). Add doc for Nindy-specific
3592 command line flags for specifying target serial port and such.
3593 Update copyright to 1991.
3595 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3596 has taken over for us the job of ripping up executable files. The
3597 crud caused Per Bothner's port to not compile.
3599 * infrun.c (normal_stop): Avoid printing "Program exited
3600 normally" if we are in batch mode. This allows a GDB which
3601 executes a program on a target system, to behave like a Unix
3602 command (input from stdin, output to stdout, no extraneous
3605 * main.c (main): Allow additional machine-dependent command line
3606 options to be specified with the ADDITIONAL_OPTIONS,
3607 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3608 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3609 processing to occur just before the main loop with
3610 BEFORE_MAIN_LOOP_HOOK.
3611 (main): If a "core file" argument is specified, and it is not a
3612 core file, try it as a process ID to attach.
3613 (symbol_completion_function): Attempt to cope with
3614 "show screen-" TAB, not very successfully. This needs more work,
3616 (batch_file): New function, returns whether we are reading
3617 commands from an interactive tty on stdin, or from somewhere else.
3618 Called by normal_stop since it doesn't get from_tty passed down
3619 to it like many commands do.
3621 * remote-nindy.c: Handle command line options for nindy
3623 (nindy_before_main_loop): Prompt user for tty name if they
3624 don't specify it before getting to the interactive command loop.
3626 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3627 and -r command line options. Also add hook before main loop
3628 to make it easy to specify a tty.
3630 * TODO: More things to do, one done.
3632 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3634 * dbxread.c: Make complaint() calls pass pointer, not struct.
3635 Add complaints about badly formatted C++ type information
3636 (const/volatile indicator, and parse errors resulting in
3637 error_type). Fix C++ virtual member fn comment.
3638 (read_struct_type): Avoid bumping pointer if we got a parse
3639 error; this prevents our walking beyond the end of a string.
3640 Terminate loop on null char as well as semicolon.
3641 (process_one_symbol): Fix the LBRAC fix so that it uses the
3642 last previous SLINE, FUN, or SO record's PC address. C++ debug
3643 symbols did not have SLINE records in a useful order compared
3644 to the LBRAC records.
3645 (define_symbol): Handle "catch" records.
3647 * symtab.c (check_stub_type): Added new complain
3648 `stub_noname_complain' and added a consistency check to
3649 keep the debugger from crashing when finishing from an
3650 exception frame. A real fix will be needed later.
3652 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3654 * infcmd.c (attach_command): Make global.
3656 * Makefile.dist (REMOTE_OBS): Make these compile by default,
3657 but make them easy to comment out. Perhaps later they should
3658 be enabled by what CPU you configure for? FIXME.
3659 (VERSION): Roll to 3.93.
3660 (pinsn.o): Remove rule for obsolete file.
3661 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
3663 Run down a problem that manifested by printing the wrong function
3664 name in stack traces of read_ofile_symtab. Turned out that the
3665 problem was the SunOS 4.1.1 (and previous) C compiler outputs
3666 the LBRAC symbol with an address in the *data* segment, which
3667 blew our binary search through the blocks.
3669 * dbxread.c: Use the complain() facility consistently to bitch
3670 about problems in the symbol file we are reading.
3671 (finish_block): Add code to check the nesting of the blocks;
3672 complain and Procrust them to fit if wrong.
3673 (make_blockvector): Check the order of the blocks, complain
3674 [but don't cope] if wrong.
3675 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
3676 symbols to be sure their PC value is greater than the last SLINE
3677 (line number) symbol we've seen, complaining and adopting the
3678 SLINE PC value if wrong.
3680 * symfile.h (struct complaint, complaint_root, complain,
3681 clear_complaints): Add.
3682 * symfile.c (complain, complaint_root, clear_complaints): Add
3683 facility to deal with non-fatal complaints and to regularize their
3685 (symbol_file_add): Clear complaint counters to allow new complaints.
3686 (initialize_symfile): Add 'set complaints' and 'show complaints'.
3688 * dbxread.c (dbx_symfile_read): Remember the address and size
3689 of the string table for the main symbol file, so we won't read it
3691 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
3692 to avoid reading the string table yet again. Lint.
3693 (throughout): Improve filtered output, including word wrap.
3694 (read_range_type): Improve Bothner's fix to handle other types too.
3696 * utils.c: Improve line wrap implementation. Handle unlimited
3697 width by making chars_per_line unsigned.
3698 (puts_filtered): New, easy, function.
3700 * defs.h (puts_filtered): add.
3702 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
3703 call the identical sort_symtab_syms() in symfile.c instead.
3705 * expread.y: Suggest the `file' command rather than `symbol-file'.
3707 * command.h (enum var_types): Add zinteger for seroable
3709 * command.c (do_setshow_command): Handle var_zinteger. Restructure
3710 nested if's into a switch.
3712 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
3713 we did not stop because of a breakpoint (it must have been for
3714 some other reason, like a "stepi"), so don't print anything.
3716 * symtab.c: Include <sys/types.h> all the time. Now that BFD
3717 doesn't include <sys/types.h>, old SunOS's require it for
3720 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
3722 A test port of gdb-3.92.6 to the Sony NEWS.
3725 Don't normally link in remote- or vx stuff.
3726 Some of it doesn't compile, and it wastes space for 99% of the users.
3727 Remove reference to no-longer-used HAVE_VPRINTF.
3728 Fixed BFD_DEP typo to BFD_DIR.
3730 Fix cast in arg to bfd_h_getlong.
3731 Make char *prefix be const.
3732 Fix how certain range types are mapped into builtin unsigned int types.
3734 Remove 2 #includes. They cause errors (on Sony, at least),
3735 and aren't needed (they wern't in earlier versions).
3737 print_address_symbolic should never demangle labels
3738 (since it prints *assembler-level* labels).
3740 [This was superseded by the change to printcmd below.]
3743 Add some "volatile" return types to avoid warnings.
3744 If MISSING_VPRINTF add vprintf function and not just macro
3745 (since vprintf is used in printcmd.c).
3747 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
3748 (The latter isn't grokked by some PCC-based compilers.)
3750 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
3752 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
3753 * nindy-share/coffstrip.c
3754 Added some forward declarations (otherwise, gcc complains
3755 about implicit extern redefined as static).
3757 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3759 Changes inspired by Per Bothner:
3760 * printcmd.c (print_address_symbolic): Take additional parameter
3761 specifying whether to demangle.
3762 (print_address): Pass in asm_demangle to control demangling.
3763 (print_address_demangle): New fn, takes explicit arg to control
3765 * utils.c: Add new vars demangle and asm_demangle, and let them
3767 (fputs_demangled): If !demangle, just print the argument.
3768 (fprint_symbol): If !demangle, just print raw symbol.
3769 * valprint.c (val_print): Call print_address_demangle rather than
3770 print_address, to cause demangling to depend on the global
3771 rather than assembler-level demangling setting.
3772 * WHATS.NEW, gdb.texinfo: Document.
3774 * main.c (show_command): Show all settings if no arg.
3775 (initialize_main): Make "info set" the same as naked "show".
3776 * command.c (cmd_show_list): Handle prefix commands in the
3777 list, and print the name of the setting as well as its English
3778 description and value.
3780 Allow gdb functions to specify where a line should wrap if it
3781 exceeds the size of a terminal line. Use it to make the output
3783 * utils.c (set_screen_width_command): New fn, mallocs a buffer
3784 of the right size when screen width changes.
3785 (set_screensize_command, screensize_info): Remove #if 0'd fns.
3786 (wrap_here): New fn, indicates a point in the output where we
3787 should wrap the line rather than just letting it overflow at a
3789 (fputs_filtered): Implement wrapping.
3790 (n_spaces): New fn, returns a pointer to N spaces.
3791 (print_spaces_filtered): Use n_spaces.
3792 * defs.h (n_spaces): Declare.
3793 * stack.c (print_frame_info): Wrap with 4-space indent after
3794 fn name and before filename and line number.
3795 * printcmd.c (print_frame_args): Wrap with 4-space indent
3796 before each argument name is printed.
3797 * valprint.c (value_print): Wrap with no indentation before
3799 (val_print_fields): Wrap with indentation relative to nesting
3800 level before each field name.
3801 (val_print): Wrap with nesting indentation before array elements.
3802 * command.c (do_setshow_command): Avoid extra newlines,
3803 wrap with 4-space indent around values printed, end with period.
3804 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
3806 * breakpoint.c (breakpoint_1): Implement addressprint for
3807 "info breakpoints" display. Change file name and line number
3808 format to " at file:nnn" rather than " (file line nnn)".
3809 * gdb.texinfo: Document.
3812 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3814 Frozen for gdb-3.92.6 release.
3816 README, WHATS.NEW: Update for 3.92.6 release.
3818 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
3819 coffread.o from configs since it is now built by default.
3820 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
3821 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
3822 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
3823 from configs since it is now built by default.
3825 Makefile.dist: Update for release 3.92.6. Handle files that
3826 have been moved to ../include, ../getopt, or ../bfd. Add
3827 saber.suppress and tests directory. Add config.status to
3828 the release (it will say "none").
3830 coredep.c: Minor formatting fixes.
3832 These changes were made in early December but only checked in now:
3833 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
3834 nindy-share/nindy.c: lint
3835 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
3836 register values coming back from the target; we store values
3837 in target byte order everywhere.
3839 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
3841 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
3843 * valprint.c (cplus_val_print, val_print_fields): New functions,
3844 which print C++ objects. They conspire to avoid printing a
3845 virtual base class more than once, following all the twists and
3846 turns of C++ virtual base rules.
3847 (val_print): Call the above rather than do it by hand.
3849 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
3850 symbol file, not for added files like shared libs. This really
3851 needs to be generalized to a timestamp per file.
3853 * core.c (cleanup_core): Avoid coredump if no core file.
3855 * config.gdb: Accept -host or -target in place of +host or
3858 * coffread.c (find_linenos): Avoid desupported BFD interface
3859 to line numbers. We still read them manually rather than using
3860 BFD's "generic" features.
3862 * gdbrc.tex, threecol.tex: Add GDB reference card and its
3864 Makefile.dist: Add refcard to OTHERS list for creating tar files.
3866 * Makefile.dist: Eliminate use of $< in explicit targets.
3868 * readline/Makefile: Use $< rather than $*.c, which does not
3869 include the VPATH in GNU Make.
3871 * tconfig/i960-bout, tconfig/i960-coff: These are identical
3872 copies of tconfig/i960, added for global configuration
3873 compatability. All i960 versions can read both coff and b.out.
3875 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
3876 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
3879 * TODO: Think of more things to do.
3881 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
3883 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
3884 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
3885 64-bit float conversion.
3887 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
3888 equivalent to sun?os4 so global config works.
3890 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
3892 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
3894 * main.c: Only declare linesize once; declare pagesize not at
3895 all, since it is never used.
3896 (main): Clear newly allocated line before it is used.
3898 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
3900 Further stabilization for the Intel 960.
3902 * Makefile.dist: Parameterize the location of the "include"
3903 and "bfd" directories, as well as "getopt". Add symfile.c.
3904 Link in both dbxread and coffread. Fix up "make depend" to
3905 rewack the locations of include, bfd, and getopt in its output.
3907 * README: Document moving include files, improve some of
3910 * coffread.c: Move common code out to symfile.c. Change
3911 symbol_file_command style interface to use new *_symfile_init
3912 and *_symfile_read interface under BFD. Use BFD internal
3913 info to locate line table, symbols, etc.
3915 * core.c (core_fetch_registers): Rename to get_core_registers
3916 to avoid confusion with fetch_core_registers.
3917 (register_addr): Move to coredep.c, which is already machine
3918 dependent. This leaves core.c pretty clean of dependencies.
3920 * coredep.c (register_addr): Accept this routine from core.c.
3922 * dbxread.c: Move common code (with coffread.c, etc) into new
3923 symfile.c. Each psymtab now contains a pointer to the
3924 format-dependent function that knows how to read it in. Make
3926 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
3927 (process_one_symbol): Add code to complain about a "compiler bug
3928 we muzzle here", if we actually see it.
3930 * eval.c (evaluate_subexp): Insert missing "break" statements
3931 in code that determines whether a variable is an lvalue in
3932 memory, register, or whatever. I detected this via a compiler
3933 bug in which it *almost* mashed out the whole switch statement.
3935 * gdb-int.texinfo: Add minor sections on configuring gdb for
3936 release, and about the README file.
3938 * infcmd.c (registers_info): Fix formatting somewhat. Still
3939 not as pretty as before, but it handles byte swapping.
3941 * remote-nindy.c: If data cache routines are interrupted while
3942 waiting for the remote end, be sure that any uninitialized cache
3943 blocks are on the free list, not on the valid list!
3945 * symfile.h: Flesh out this header file with all the various
3946 routines and variables that have been merged in from dbxread.c
3947 coffread.c, and symtab.c to symfile.c.
3949 * symfile.c: New file, containing code common to dbxread.c,
3950 coffread.c, and some code from symtab.c. All generic code for
3951 reading symbol files should be in here now.
3952 (unrecord_misc_function): Remove unused function.
3954 * symtab.h: Remove file-reading things to symfile.h.
3956 * symtab.c: Remove file-reading things to symfile.c.
3958 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
3959 to decode i960 fault types.
3961 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
3962 target.c: Change type of the "resume" function from int to void,
3963 since its result was never used.
3965 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
3967 * main.c: Replace "stupid" with "caution"; you now "set caution
3970 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
3972 * infcmd.c (do_registers_info): Call val_print to deal with the
3973 byte order of the registers being printed. FIXME, this makes
3974 the formatting of the output uglier.
3976 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
3977 defined, call it for signals the debugger doesn't itself use.
3978 The i960 uses this for more detailed fault information.
3980 * remote.c (remote_open): If arg is null, print help rather than
3983 * sparc-xdep.c (register_valid): Avoid declaring size, since
3984 various modules will think of various sizes depending on the
3985 architecture of their tm-file. FIXME, we need protection against
3986 actually entering one of those modules, which would clobber
3987 storage if not for the target architecture compiled into gdb.
3989 * stack.c (up_command, down_command): Always print the frame
3991 (up_silently_command, down_silently_command): New commands
3994 * i960-pinsn.c (reg), i960-tdep.c: Lint.
3996 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
3997 more parameters than it used to.
3999 * findvar.c (registers): Increase slop to 256 bytes, which should
4000 protect us against even most RISC machines with large register
4002 (locate_var_value): Move declaration inside related ifdef.
4004 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4005 throughout, to avoid throwing away buffered input from the board.
4006 (nindy_wait): Supply_register takes addr_of_value, not value.
4007 (i960_print_fault): Renamed from i80960_fault.
4008 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4009 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4011 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4012 we can set the PC in the call to proceed(). Unpush nindy_ops
4013 before pushing it on top, to avoid message to user. Eliminate
4014 commentary from Unix machines that just misleads here.
4015 (reset_command): Fix error message to suggest target command.
4017 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4019 Release 3.92.5 as frozen.
4021 Stabilize the merged release...with help from lint, Saber C,
4024 Everywhere: Add include files needed to declare return types
4025 of functions called.
4027 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4029 * breakpoint.h: Add undeclared breakpoint functions, and some
4030 functions for display handling since I couldn't think of a better
4033 * breakpoint.c (insert_breakpoints): Make code for disabling
4034 shared library bkpts more likely to work. It's used when we
4035 rerun a program and stop before the shared library has been
4037 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4038 cast from pointer, so it squeezes through catch_errors.
4039 (bpstat_stop_status): Fix logic broken some time ago. We now
4040 always create a bpstat if the stop address matches a breakpoint,
4041 even if we don't stop there -- just like the old code used to do
4042 before I got my fingers into it (sigh).
4043 (breakpoint_1): Print "ignore count" after "stop only if"
4044 condition, since that's how it actually works.
4045 (mention): Handle watchpoints as well as breakpoints.
4046 (watch_command): use set_raw_breakpoint and mention to do most
4047 of the work (and initialize all the fields!). Only pass one
4048 arg to parse_c_expression, since that's all it takes.
4050 * command.c (not_just_help_class_command): Rename arg to args
4051 since we ignore "unused argument" warnings on vars named "args".
4052 inflow.c (child_terminal_info): ditto.
4053 infptrace.c (kill_inferior): ditto
4054 main.c (catch_errors, version_info, quit_command, pwd_command,
4055 source_command, dump_me_command, editing_info,
4056 set_history_size_command, set_history, show_history,
4058 stack.c (locals_info): ditto
4059 target.c (target_files_info): ditto
4060 valprint.c (set_input_radix, set_output_radix): ditto
4062 * core.c: Remove old variables for handling core and exec file
4063 sections (data_start, data_end, stack_start, stack_end,
4064 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4065 text_end, exec_data_start, exec_data_end, text_offset,
4066 exec_data_offset, data_offset, stack_offset). They're
4067 superseded the more general build_section_table and
4069 (get_exec_file): Mention the `file' command.
4070 (read_memory_check): Rename to memory_error, and only call it
4071 in the case of an actual error.
4072 (read_memory, write_memory): call memory_error.
4073 (core_fetch_registers): Register section name is ".reg".
4075 coredep.c: Remove a bunch of crud now that all this file does
4076 is pull the registers out of a core file.
4077 (fetch_core_registers): Rewrite to actually work, I hope.
4079 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4080 Replace index() with strchr(). Remove all the pre-BFD macro
4081 definitions for accessing the symbol file.
4082 (struct dbx_symfile_info): Encapsulate the information that
4083 dbx_symfile_init needs to pass to dbx_symfile_read in this
4086 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4087 dbx_symfile_discard): Rearrange symbol file reading to divide
4088 the format-specific part from the format-independent part,
4089 leaving the format-independent part such as file name expansion
4090 and opening in symtab.c. This replaces
4091 partial_symbol_file_open and partial_symbol_file_read.
4092 Symbol_file_read, add_file, add_file_target_command,
4093 add_file_addr_command move to symtab.c. Pass an explicit
4094 "mainline" flag for when reading the main symbol table, rather
4095 than relying on the offset address to be zero or nonzero.
4097 (dbx_symfile_read): Don't allow void *'s to be printed as
4099 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4100 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4101 macro" debug version really work.
4102 (read_dbx_symtab): Remove unref'd parameter inclink.
4103 Avoid swapping N_SLINE symbols, for speed.
4104 Merge N_TEXT!N_EXT case with the other external symbol
4105 definitions' case. Add comments.
4106 (start_psymtab): Allocate the symfile name in the psymtab on
4107 the psymbol_obstack, rather than using the caller's storage.
4108 (end_psymtab): Only allocate a dependencies list if there are
4110 (psymtab_to_symtab_2): Use BFD when reopening file to read
4111 its symbols for real.
4112 (read_struct_type): Add FIXME comments where it needs work
4114 (read_huge_number): Add FIXME about overflows.
4115 (read_range_type): Add FIXME about comparing a long to 1<<32.
4117 * coffread.c: Minor changes to move things closer to the new
4118 regime with symtab.c and dbxread.c Major work is still needed
4121 * exec.c (exec_file_command): Remove old variables (see core.c
4123 (xfer_memory): If memory transfer is right at the end of a
4124 section, don't lose.
4126 * findvar.c (get_saved_register): If value is in a real
4127 register, LVAL is lval_register, not lval_memory.
4129 frame.h: Declare print_sel_frame and record_selected_frame.
4131 gdb-int.texinfo: New file, for GDB internals documentation.
4132 Very simple, unformatted doc of cleanups is there for now.
4134 gdbcore.h: Remove obsolete variables that described a.out
4135 section addresses and offsets. (See core.c above.)
4136 Declare fetch_core_registers and registers_fetched.
4138 getopt.c: Declare char *alloca(); even on SPARC.
4140 infcmd.c (run_command): Call target_kill rather than
4142 (step_command, next_command, stepi_command, nexti_command):
4143 Declare from_tty parameter even though we don't use it.
4144 (run_stack_dummy): argument BUFFER is a char array, not
4145 a pointer to REGISTER_TYPE.
4146 (finish_command): using_struct_return needed a value *,
4147 not a struct symbol *.
4149 * infptrace.c (child_xfer_memory): To avoid dependency on
4150 where sections are in memory, try PT_WRITE_D and if that fails,
4151 try PT_WRITE_I. Most Unixes don't care which you use.
4153 * infrun.c (step_resume_break_shadow): Change to array to
4154 match other breakpoint shadow storage.
4155 (clear_proceed_status): Pass address of bpstat to
4156 bpstat_clear, not the bpstat itself.
4157 (child_create_inferior): FIXME comment about if the child
4159 (start_inferior): Remove old function.
4160 (child_open): Use target_kill rather than kill_inferior.
4161 (wait_for_inferior): Ditto.
4162 (insert_step_breakpoint, remote_step_breakpoint): Use
4163 new step_resume_break_shadow.
4165 * inftarg.c (child_wait): If all child processes die,
4166 pretend that the one being waited for exited with signal 42.
4168 * main.c (command_line_input): When scanning for comments,
4169 don't coredump on unclosed quotes.
4170 (quit_command): Use target_kill rther than kill_inferior.
4171 (_initialize_main): Rename class_user from "user" to
4174 * printcmd.c (print_command_1): Initialize "fmt" if no format
4175 is specified by the user.
4176 (print_frame_args): Only add to args_printed if we are
4177 actually fetching args from the stack (avoiding undefined
4179 (_initialize_printcmd): Remove bogus \{ from string.
4181 * remote-eb.c (eb_open): Avoid coredump on no argument.
4183 * remote-nindy.c: Bring out of Intel environment into new
4184 target environment. Remove all conditional compilation on
4185 I80960. Massive hacking throughout.
4186 (nindy_xfer_inferior_memory): New routine stolen from
4188 (nindy_create_inferior): New routine pieced together, probably
4189 not quite working yet.
4190 (nindy_ops): New target_ops struct for nindy.
4192 * remote-vx.c: Use write_memory rather than target_write_memory
4193 to get error checking.
4194 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4196 (vx_create_inferior): Use target_terminal_ours...
4198 * signame.c (_initialize_signame): Always initialize, since
4199 we need the table for things other than psignal.
4201 * solib.c (solib_add): Use symbol_file_add, not add_file.
4202 (solib_address): Return boolean result rather than struct
4203 pointer which nobody else knows the type of.
4205 * sparc-tdep.c, valops.c: Use write_memory rather than
4206 target_write_memory, to get error checking.
4208 * stack.c (locals_info, catch_info, args_info,
4209 get_selected_block, frame_command, up_command): Use
4210 target_has_stack, rather than have_inferior_p or
4213 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4215 * symfile.h: New file, defining the interface between the
4216 generic and object-file-specific symbol reading code.
4218 * symtab.c: Move generic symbol-reading interface to symtab.c,
4219 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4220 table to map BFD targets to symbol-reading modules in GDB.
4221 Change index to strchr.
4222 (lookup_struct_elt_type): Use error() rather than hand-made
4223 simulations thereof.
4224 (lookup_partial_symbol): Speedup slightly when length == 0.
4225 (symbol_file_add): New function.
4226 (symbol_file_command): Call it.
4227 (symfile_open, symfile_init): New function.
4228 (add_file_target_command, add_file_addr_command): moved from
4231 * target.c (target_command): use target_kill.
4233 * target.h (target_files_info): Don't declare, never called
4236 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4237 files to determine stack end address.
4239 * valarith.c (value_x_binop, value_x_unop): Change error message
4240 to be more useful. Pass proper argument to value_struct_elt.
4242 * valops.c (value_assign): FIXME comment that long long
4243 bitfields will break here.
4245 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4246 Update `make saber_gdb' to work better.
4248 * TODO: A woman's work is never done.
4250 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4251 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4252 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4253 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4254 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4255 valops.c, valprint.c, exec.c: Lint.
4258 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4260 Continuing Intel 960 port merge of GDB.
4262 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4263 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4264 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4265 Wack over "make depend" so it handles files in subdirectories
4266 vx-share, nindy-share, bfd, and in the current directory.
4268 * blockframe.c (get_prev_frame_info): Remove fatal error
4269 if stack not defined.
4271 * core.c (core_open, core_detach): New functions that handle
4272 the old "core-file" command as "target core" and "detach" instead.
4273 (core_file_command): Call them.
4274 (core_xfer_memory): Use common routine xfer_memory.
4276 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4277 dbxread now uses bfd for everything but symbol reading itself.
4278 BFD internals are used to drag out the relevant file offsets.
4279 (partial_symbol_file_open): Change args all around for BFD.
4281 * symtab.c: Rename "value" to "val" everywhere, so we can
4283 (symbol_file_command): New command, moved from dbxread.c
4284 and coffread.c. It uses BFD to read the file, then vectors
4285 based on its type, to dbx or coff symbol readers.
4286 * symtab.h: Extern a few vars for symbol_file_command.
4288 * target.h: Breakpoint takes a char * save area, not a char **.
4290 * valprint.c (val_print): When unpacking bitfields, offset
4291 the address in gdb of the value, if it is declared with a shorter
4292 type. Remove the last "runtime kludge test" of host byte order.
4294 * utils.c: Remove old my_bfd_read routine.
4296 * stack.c (frame_info): Use target_has_stack. Print program counter
4297 register's actual name rather than "pc", since it's called the
4298 "ip" (instruction pointer) on the i960 (sigh).
4300 * target.c (target_command): Add command for selecting a target
4301 type and calling its open routine. This is used for initiating
4302 communication with a particular target, in a generic way.
4304 * tm-i960.h: Update for modern gdb. Remove semicolons from
4305 various macros. Handle reading struct return convention, and
4306 error-out attempts to return structs with the "return" command.
4307 Be sure gdb doesn't think we know how to call functions in the
4310 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4311 to i960_xxx in lower case.
4312 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4313 not being defined yet.
4315 * remote.c (remote_open): Call start_remote to initialize
4316 wait_for_inferior during open.
4317 (remote_xfer_inferior_memory): Return length written rather
4320 * remote-vx.c (target_command -> vx_open): Use new generic
4322 * remote-eb.c, inftarg.c, exec.c: ditto.
4324 * infrun.c: Fix comments.
4325 (attach_program -> child_open): Use new generic target command.
4326 (wait_for_inferior): Clear saved register values before target_wait,
4327 so target_wait can set some of them if convenient.
4329 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4330 Return success indicator, not void.
4331 (child_xfer_memory): Avoid fetching initial word if we'll
4332 overwrite it anyway.
4334 * infcmd.c (attach_command): Use new generic target open routine.
4335 (_initialize_infcmd): Update doc on attach and detach commands.
4336 (do_registers_info): Merge in a byte-order problem as a FIXME
4339 * findvar.c (find_saved_register): Avoid problem in current frame.
4340 (read_relative_register): Ditto.
4341 (write_register): Convert byte order on the way out.
4343 * exec.c (file_command): Add.
4344 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4345 (xfer_memory): Common function between core_xfer_memory and
4347 (exec_xfer_memory): Use it.
4349 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4351 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4352 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4353 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4355 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4357 Merge Intel 960 port of gdb, continuing...
4359 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4360 symbol_file_command): Pass from_tty arg to hush 'em up.
4362 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4363 Add magic numbers for 960 COFF format.
4365 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4367 Merge Intel 960 port of gdb, from Intel "1.2" release.
4369 CHANGE_LOG entries from their port, which was based on

4373 Remove temp file if download is interrupted.
4375 Wed Aug 1 09:08:33 PDT 1990
4376 Now uses binary protocol to talk to NINDY.
4377 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
4378 Times out after 5 seconds when trying to talk to NINDY.
4380 Tue May 29 12:54:49 PDT 1990
4381 Added variable baud rate (-b switch).
4382 Source code reorganization.
4384 Thu Apr 26 11:09:55 PDT 1990
4385 More cleanup of batch mode; specifically, execute "-s", "-e", and
4386 "-se" switches as soon as they are encountered on the invocation line.
4388 Fri Apr 20 13:47:15 PDT 1990
4391 Thu Apr 19 09:54:28 PDT 1990
4392 Add 'reset' command.
4394 Wed Apr 18 09:48:07 PDT 1990
4395 After opening remote tty, wait for 1 second to go by without input
4396 from it before trying to talk to NINDY (fixes problems with the
4397 Heurikon HK80/V960E).
4399 Mon Apr 4 16:33:05 PDT 1990
4400 Some output was not being suppressed in 'batch' mode.
4402 Thu Mar 22 15:31:11 PST 1990
4403 Ask user if old symbol table should be deleted when new file is
4406 Allow user to run a program downloaded before gdb960 was brought up.
4408 Correct "exec-file" help message for i80960 context.
4410 Correct bug in calculating user space address: could occasionally
4411 corrupt user program.
4413 Make sure to zero low-order bits in rip's because of bug in 960CA
4414 A-step part: could cause operation faults when "next"ing across
4417 Correct bug that made it impossible to get source line numbers for
4418 code loaded at addresses higher than 0x7fffffff.
4420 Wed Jan 10 12:43:22 PST 1990
4421 Open remote tty for exclusive use.
4423 Fri Jan 5 12:14:42 PST 1990
4424 Correct disassembly (CA manual was right after all):
4425 opcode for sysctl is 0x659
4427 Mon Oct 23 12:03:04 PDT 1989
4428 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4430 Mon Oct 16 14:15:09 PDT 1989
4431 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4433 Mon Oct 2 15:56:31 PDT 1989
4435 Added 960CA disassembly support.
4437 To simplify maintenance:
4438 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4440 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4441 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4442 - made disassembly interface identical to that in gdmp960.
4446 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4448 * target.h: Allow targets to stack. Add target_has_memory,
4449 _registers, etc. Restructure memory access and "info files"
4450 to walk the target stack.
4451 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4452 target.c: Change tables to match target.h.
4453 * inflow.c (child_mourn_inferior): pop child_ops.
4454 (generic_mourn_inferior): Use new has_stack flag.
4455 * infptrace.c (child_xfer_memory): New memory regime.
4456 * inftarg.c (child_files_info): New "info files" regime.
4457 * remote-eb.c: New memory regime, new info files.
4458 * remote-vx.c: New memory regime, new info files. Now use
4459 separate targets for VxWorks attachment to machine, and
4460 actually running a process under VxWorks, since one has
4461 stack & execution & regs and the other doesn't.
4462 * remote.c: New memory regime, new info files.
4463 * sparc-xdep.c (fetch_core-registers): New memory regime.
4464 * target.c: New routines and support for stacked targets,
4465 new memory regime, new info files regime.
4468 Generalize section handling for an arbitrary number of sections,
4469 including use of the new BFD (binary file) library.
4470 * gdbcore.h: Add struct section_table.
4471 * exec.c (build_section_table): Iterate all sections and
4472 record what gdb needs to know about them.
4473 (exec_command): Use it.
4474 (exec_xfer_memory): Use the table.
4475 (exec_files_info): Print the table.
4476 * core.c (core_file_command, core_xfer_memory, core_files_info):
4478 * source.c (find_source_lines): Use bfd_get_mtime.
4479 * dbxread.c: Quick changes to make it compile with new BFD.
4480 * utils.c (error): Avoid using bfd_error in generic routines.
4482 * core.c (core_fetch_registers): Get from the ".regs" section of
4484 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4486 * inferior.h (attach_flag): Export.
4487 * infcmd.c (run_command): use new target_create_inferior.
4488 * infrun.c (child_create_inferior): Don't return result.
4489 * Makefile.dist (VERSION): 3.91.4.
4491 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
4493 * breakpoint.c (bpstat_num): Handle breakpoints which have
4494 since been deleted, such as temporary breakpoints.
4495 infcmd.c (program_info): ditto.
4497 * core.c (core_file_command): Display the frame where the core
4502 * remote-vx.c (target_command): Merge in target command from
4503 targ-vx.c. A few other cleanups.
4505 * TODO, Projects: Lots more stuff to do...
4507 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4509 Massive changes to wall off the remote-debugging interface
4510 behind a function vector. The port to handle VxWorks targets
4511 is also part of this.
4513 All files: Replace references to renamed functions,
4514 remove references to remote_debugging, remove references to
4515 have_include_file, have_core_file in favor of target_has_stack,
4516 target_has_memory, etc.
4518 * Modularize the breakpoint interface.
4519 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4520 a breakpoint instruction.
4521 breakpoint.c: struct breakpoint's shadow_contents now sized as
4523 (insert_breakpoints): Vector to target to install breakpoints.
4524 (remove_breakpoints): Vector to target here too.
4525 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4526 sparc-tdep.c (single_step): Use new breakpoint interface for
4527 the single-step breakpoints.
4528 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4529 New file, contains routines to insert and remove breakpoints by
4530 reading out the old contents and later replacing them. This is
4531 how ptrace breakpoints work, and many remote systems as well.
4533 * tm-vxworks68.h: New config file, overrides a few things for
4534 Wind River's preferences.
4536 * target.h: New file, for transfer vector used to talk to the
4537 inferior (child, attached, core, exec, remote, etc). All accesses
4538 to the thing being debugged should come through these vectors.
4539 target.c: New file, routines to handle transfer vector.
4540 (various files): Add transfer vectors XXX_ops for the various
4541 targets and pseudo-targets (core files, etc) we support.
4543 * breakpoint.c (bpstat_stop_status): Further explorations of
4544 watchpoints and why things don't work all the time.
4545 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4547 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4548 the local gdbinit if it doesn't already have it.
4550 * core.c (core_ops): add and install.
4551 Allow core debugging without exec file.
4553 * dbxread.c (free_and_init_header_files): Merge two fns.
4554 (end_symtab): Free named symbol table when a new version comes in.
4555 (read_dbx_symtab): Relocate all kinds of symbols with base
4556 address. First step toward handling different text, data, bss
4558 (add_file_addr_command): Renamed add_file_command.
4559 (add_file_command): Vector to remote handler.
4560 Add "load" as an alias for "add-file" command.
4562 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4563 non-returning functions.
4565 * exec.c: Add exec_ops, and push it as a target when an exec
4568 * infcmd.c (run_command): Pass executable file name and arg list
4569 separately when starting an inferior. Permit "run" when no exec
4570 file is specified, for VxWorks.
4571 (detach_command): Move to child_detach in inftarg.c.
4573 * inftarg.c: New file. Unix-child-specific routines, and the
4574 child_ops structure.
4576 * inferior.h (registers): Export "registers" as the way for
4577 target dependent register handlers to find gdb's local copy of
4578 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4579 since it is now used by places that want wait_for_inferior to
4580 handle the grunge but want to see every trap from the inferior.
4582 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4583 Eliminate remote_debugging hooks in terminal handling.
4585 * infrun.c: Replace start_inferior with child_create_inferior.
4586 Move all the hair of Unix shells and ptrace idiosyncracies into
4587 child_create_inferior, so remote handlers don't have to deal.
4588 Remove running_in_shell. Rename stop_after_attach to
4589 stop_soon_quietly, and use it in a few other places where we want
4590 to just call wait_for_inferior and get control back on the first
4591 trap. trap_expected now never takes a value > 1.
4592 (init_wait_for_inferior): Initialize static vars when a new
4595 main.c (gdbinit): Add new hook for .gdbinit file name, let
4596 it be overridden by config files as GDBINIT_FILENAME.
4597 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4598 Both of these are used for VxWorks gdb.
4600 mcheck.c: rename include file "gmalloc.c" to avoid problems
4601 with system include file "malloc.c".
4603 param-no-tm.h: New include file, same as param.h but does not
4604 include the default "tm.h" file. This is used in files where
4605 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4607 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4609 remote-vx.c: New file, VxWorks remote debugging support. Uses
4610 RPC routines that are shared with the target system, in directory
4613 remote.c: Vectorize remote interface.
4615 source.c: Globalize source_path, and make an alias "l" for "list"
4616 since we now have the "load" command.
4618 sparc-xdep.c: Use new param-no-tm.h.
4620 symmisc.c (free_named_symtab): Add new function from Wind River.
4621 However, ifdef it out for now while we think about what it should
4624 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4626 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4627 non-Unix-children handle this with their own code in the target
4630 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4631 source and target lists. Add vx-share to default list of include
4632 directories. Add new files to src and target lists: mem-break,
4633 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4634 ${srcdir} versions of munch and createtags are used.
4636 * valops.c (find_function_addr): Split out of call_function.
4637 (call_function_by_hand): Rename call_function; this function
4638 calls functions in the target by laboriously patching the target
4639 word-by-word with the right stack, args, regs, etc.
4642 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
4644 Handle AMD 29000 a bit better.
4646 * remote-eb.c (readchar): Mask received char log to make it readable.
4647 (remote_start): Pass arguments down to executing program.
4648 Make startaddr unsigned.
4649 infrun.c (start_inferior): Accept args, pass them to
4651 infcmd.c (run_command): Pass args down to start_inferior.
4653 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
4654 the target object file format.
4655 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
4657 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
4658 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
4660 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
4662 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
4663 * TODO: We did a few things, we have more to do though.
4665 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
4666 * inflow.c (inferior_died): Clear deferred stores.
4668 * Debug problems with dummy frames and calls to the inferior.
4669 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
4670 * sparc-tdep.c (do_restore_insn): Simplify.
4671 (sparc_frame_find_saved_regs): Simplify and fix what we find.
4672 (sparc_push_dummy_frame): Simplify and fix what we push.
4673 (sparc_pop_frame): Slightly more hair here, deciding whether
4674 we are restoring a saved PC or returning to a return address in %i7.
4675 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
4677 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
4678 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
4679 * obstack.h (chunkfun): ditto.
4680 * defs.h (xmalloc, xrealloc): ditto
4682 * utils.c (quit): Grab the terminal from the child if necessary.
4684 * inflow.c (term_status_command): Rename to term_info, change
4687 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
4688 (is_delayed_branch): Speed up.
4689 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
4690 Still missing some float ops, and needs testing.
4692 * Support for input and output radixes other than base 10
4693 * defs.h (input_radix, output_radix): Declare.
4694 * expread.y (yyparse, parse_number): Handle changes of input
4695 radix, and ambiguous names-or-numbers in radixes >10.
4696 * printcmd.c (print_scalar_formatted): Print formatted hex
4697 numbers in varying column widths.
4698 * valprint.c (val_print): Use output_format to print scalar ints.
4699 (set_input_radix, set_output_radix, set_radix): Create.
4700 (set_output_radix): Set output_format from output_radix.
4701 (_initialize_valprint): add `set radix' but leave the others off.
4703 * main.c (execute_command): Let stupid questions be turned off.
4704 (_initialize_main): Handle "set stupidity", etc.
4706 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
4707 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
4709 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
4711 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
4712 bfd stuff is still screwed up, but with some manual work, it
4715 * breakpoint.c (bpstat_do_actions): Start over if a command
4716 proceeds the inferior, since the inferior will have stopped and
4717 will need to have its new stop-actions taken care of.
4719 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
4720 compiler fits, simplify it.
4722 * gdb.texinfo (directory command): Doc new dir command.
4723 source.c (directory_command): "dir" now puts things on the front
4724 of the path, moves dups up front, and handles multiple names
4725 on the command line, inserting each one in order. It also
4726 blows away cached line and full_filename info.
4728 * stack.c (backtrace_command): Skip "more stack frames follow"
4731 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
4732 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
4733 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
4734 The only odd one was Gould NP1, which had defined vprintf to
4737 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
4738 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
4739 variable, inspect_it.
4740 valprint.c (print_string, val_print): Use the global inspect_it
4741 to indicate whether to print in Epoch style or normal style.
4743 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
4745 * printcmd.c (call_command): add an alias for the "print" command
4746 which runs expressions and doesn't print the result if void.
4747 (print_command_1): implement it.
4749 * command.c: Remove #if 0'd code. Initialize all the fields
4750 in add_cmd (). Rename do_nothing_command to
4751 not_just_help_class_command, and make it externally visible.
4752 command.h: add user_commands to struct.
4753 * main.c (define_command): Don't overload c->function with a char
4754 string as well as a function pointer.
4756 * eval.c (evaluate_subexp): Reinstall tiemann changes to
4757 calling convention of value_struct_elt () that got dropped in
4760 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
4761 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
4763 * tm-sparc.h (POP_FRAME): replace some constants with defines.
4765 * sparc-xdep.c (store_inferior_registers): defer stores to regs
4766 until a good time (e.g. when we are about to run the child),
4767 saving ptrace calls.
4768 * infrun.c (proceed): handle DO_DEFERRED_STORES.
4769 * tm-sparc.h: define DO_DEFERRED_STORES.
4771 * sparc-xdep.c (store_inferior_registers): when storing float
4772 registers, don't store stack regs too. When storing the SP,
4773 however, DO store the stack regs too. This fixes a bug in which
4774 the dummy frame is not recognized when a call_function finishes,
4775 because its frame pointer (in the stack regs) was never
4777 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
4778 even though we don't know how to read them from an inferior.
4779 valops.c (call_function): Comment about storing SP.
4781 * infrun.c (save_inferior_status): Save away the original bpstat
4782 chain so it can be restored later. Install the copied version for
4783 use by whoever saved the status. It will be blow away by
4784 restore_inferior_status, and the original chain restored. This is
4785 important for people who have pointers into the original.
4787 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
4788 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
4789 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
4792 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
4794 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
4795 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
4796 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
4798 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
4800 * Merge Mike Tiemann's multiple inheritance changes from Sun.
4801 Store the baseclasses in a type struct starting from array element
4802 0 rather than from the unusual array element 1.
4804 dbxread.c: the above.
4805 (virtual_context): Add
4806 Read new debug information about which virtual function table
4807 a virtual function is from, and store it in fn_field.fcontext.
4809 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
4810 TYPE_FN_FIELD_STATIC_P.
4812 symtab.c: the above.
4813 valops.c: the above. Handle pointer casts of object *'s.
4814 (search_struct_method): Add.
4815 (value_struct_elt): First arg is now a pointer to a value, and is
4818 valprint.c: the above.
4819 values.c (value_virtual_fn_field): Add type arg. Handle
4820 offsetting to the proper object when calling virtual fns.
4822 (baseclass_addr): Add valuep arg.
4824 * README: Document the current state of BFD config (missing).
4825 * TODO, ChangeLog, Makefile.dist: Roll version.
4826 * WHATS.NEW: Add summary of changes since 3.5.
4828 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
4830 * dbxread.c (read_struct_type): Clear bit vectors whenever
4832 symtab.c (B_CLRALL): define.
4834 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
4835 using == rather than =. Huh... This fixes the dreaded problem
4836 wherein builtin_type_int becomes TYPE_CODE_FLT.
4838 * core.c (info_files): Show the inferior pid.
4840 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
4841 already knows how to look in the source directory.
4843 * Remove psymtab hair from many places. Remove duplicated code
4844 for searching symbol tables. Hide psymtabs from most places.
4845 Make it fast to get from a psymtab to its symtab.
4847 blockframe.c (blockvector_for_pc): Remove psymtab hair.
4848 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4849 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4850 dbxread.c: export psymtab_to_symtab, make it work if called N times.
4851 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
4852 new symtab completely. New psymtabs get symtab pointer
4853 initialized to zero. Remove MI warning printf.
4854 symtab.h: Comments. Add psymtab to symtab pointer.
4855 (PSYMTAB_TO_SYMTAB): New macro.
4856 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
4857 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
4859 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
4861 (print_frame_info): Avoid special-casing symbols that have not yet
4864 * source.c (open_source_file): Quick path if we have already
4865 located the source file by its full name.
4867 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
4868 find_pc_psymtab. When a name is found in the misc function
4869 vector, search the symbol table for its mangled name, not the
4870 name that the user typed.
4872 * bfd.h: Fix missing comment terminators, make #endifs match.
4874 * valarith.c (value_less): Handle unsigned int comparisons.
4875 Add FIXME about pointer compares, which assume host and target
4876 pointers are the same.
4878 * command.c (do_nothing_command): lint
4879 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
4880 fix comments on debug symbol format for visibility. Actually set
4881 visibility of symbols.
4882 main.c (echo_command): lint; use <readline/history.h>.
4883 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
4884 obstack.h (_obstack_blank): Rearrange pointer math to avoid
4885 pointing past end of allocated memory; saber complains.
4886 obstack.h: Declare the external functions that we use.
4887 valarith.h: use <string.h>
4888 solib.c (solib_add): lint.
4890 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
4892 * main.c (initialize_main): Default info_verbose to off, now that
4893 symbol reading is fast.
4894 (quit_command): Avoid clobbering exec_bfd while quitting.
4896 * Initial BFD (binary file diddling library) merger:
4897 coffread.c: Change AOUTHDR to struct exe_hdr.
4899 core.c: initialize initialized data at compile time.
4900 (core_file_command): Move from coredep.c, convert to bfd.
4901 (xfer_core_file): Convert to bfd.
4902 exec.c (exec_file_command): use bfd routines.
4904 mips-tdep.c: Remove exec_file_command and friends.
4907 * coredep.c: (fetch_core_registers) Convert core_file_command to
4908 fetch_core_registers.
4909 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
4911 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
4912 (my_bfd_read): More bogosity, which I don't think we call.
4913 (program_name): Remove this atrocity asap!
4915 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
4918 values.c: allocate_repeat_value was not clearing the
4919 optimized_out field.
4920 (value_static_field): minor stylistic fix (wrong macro was used).
4921 valops.c (value_struct_elt_for_address): didn't work for C++
4924 * signame.c (_initialize_signame): Initialize signal names once.
4926 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
4927 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
4928 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
4930 * remote-eb.c: Support user-settable baud rates on the serial port.
4932 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
4934 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
4936 * tconfig/sun3os4: Remove warning about native assembler,
4937 since it also occurs in the xconfig file.
4939 * findvar.c (registers): Allocate some slop after `registers'
4940 to prevent stray accesses from trashing the next variable.
4942 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
4943 on the sun-3, by changing the #ifdef from `sun3' (which is not
4944 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
4945 vars, which happened to follow `registers' in the executable.
4947 * readline/history.c (history_search): Heed gcc-2's advice
4948 and parenthesize && inside ||).
4950 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
4951 tm-29k.c: Insert FSF copyright headers.
4953 * remote-eb.c: Better comments.
4955 * Makefile.dist: Update to 3.91.6.
4956 * TODO: note PREPARE_TO_STORE problem.
4958 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
4960 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
4962 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
4964 * infrun.c (wait_for_inferior, at end): Don't set up
4965 prev_* if the inferior no longer exists.
4967 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
4968 CANNOT_EXECUTE_STACK.
4969 valops.c (call_function): Use it.
4971 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
4973 * inferior.h (PC_IN_CALL_DUMMY): New macro.
4974 infrun.c (wait_for_inferior, 2 places): Use it.
4976 * values.c (value_being_returned): Only use
4977 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
4979 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
4980 right thing for remote-eb.c.
4982 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
4983 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
4985 * blockframe.c: Put get_frame_saved_regs inside #if !defined
4986 (FRAME_FIND_SAVED_REGS).
4988 * findvar.c ({fetch,store}_registers): Check for
4989 REMOTE_{FETCH_STORE}_REGISTER macro.
4991 * findvar.c (get_saved_register): Add argument lval and
4992 change meaning of argument addr.
4993 findvar.c: Change calls to get_saved_register to reflect
4994 new calling convention.
4995 valops.c (value_assign): Use get_saved_register instead of
4996 find_saved_register.
4998 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5000 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5001 an (uninitialized) pointer to one. Use "&" when passing it
5004 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5006 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5009 * coffread.c (symbol_file_command): Put semicolon after
5011 Put safe_to_init_tdesc_context in #if defined (TDESC).
5012 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5013 coffread.c: #include <sys/stat.h>.
5014 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5015 Add missing ')' in check for "lc%" and friends. Remove
5017 Declare read_one_sym() at top of file.
5018 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5019 MC68WRMAGIC can have the same value without causing a duplicate
5022 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5024 * Allow a Makefile to be built without building the
5025 tm and xm file links that screw up builds in subdirectories.
5026 This is done with `config.gdb none', then you can do things
5027 like `make gdb.tar.Z'.
5028 * tconfig/none: Config file for no target system
5029 * xconfig/none: Config file for no host system
5030 * config.gdb: If no TM or XM files are called out by the
5031 host or target file, don't make links for them.
5033 * cplus-dem.c: Add documentation.
5035 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5036 simple error, so the user's gdb doesn't crash due to some object
5037 file problem (e.g. somebody is rebuilding the file out from under
5040 * printcmd.c (print_address_symbolic): demangle the symbol.
5042 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5043 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5044 (alldeps.mak): sort and uniq all results from this; duplicates
5045 hose gdb.tar.Z link building. Remove RCS files from
5046 tconfig and xconfig. Add config files for sun386. Add
5047 a few odd files to OTHERS and HFILES.
5049 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5051 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5052 Roll version number to 3.91.5. Make lint work in bindir.
5054 * README: Document cross-debugging and new file structure.
5056 * blockframe.c: Lint. Include "value.h" to declare read_register.
5057 (find_pc_partial_function): remove duplicate line.
5059 * command.h: Lint. Declare error_no_arg and dont_repeat.
5061 * tm-news.h: Remove inadvertently duplicated stuff.
5063 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5064 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5066 * config.gdb: Allow `config.gdb host target' form. Clean
5067 up previous change that printed bogus messages when you just said
5070 * core.c: #include "command.h" for lint.
5073 * main.c: Remove some casts of enums. Lint.
5080 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5082 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5083 read it from memory. This will allow us to save ptrace calls
5084 eventually. Changed caller single_step too.
5086 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5087 that we aren't going to use, saving many ptrace calls, especially
5088 when watchpointing or single stepping. Use some #define's for
5090 (store_inferior_registers): Ditto.
5091 (core_file_command): Use some #define's for constants.
5093 * tm-sparc.h: Add #define's for some register numbers, so we
5094 can eliminate the use of random constants in sparc-xdep.c.
5096 * stack.c (frame_command, print_frame_info, up_command,
5097 down_command) Remove frame_changed, since it
5098 causes a bug and doesn't seem to do anything useful. In some
5099 places it was used as a flag, in others as a stack level (?).
5101 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5102 default is to use the portable (vprintf) version rather than the
5104 * xm-news.h (MISSING_VPRINTF): Add.
5106 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5108 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5110 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5111 about linking debugged programs -Bstatic in the sun?os4 config
5112 files in tconfig and xconfig subdirectories.
5114 * main.c (main): Remove unreached exit(0) now that we exit
5117 * Create TODO file for online bug list. There are too many
5118 "little" bugs to keep track of on paper.
5120 * Change Projects file to refer to bug-gdb@cygnus.com
5121 rather than kingdon@ai.
5123 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5125 * Makefile.dist (VERSION): 3.91.4 now.
5127 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5128 (condense_misc_bunches): Add sanity check that misc_count is
5129 the same as the number of symbols in the bunch.
5131 * coffread.c: rename init_misc_bunches. Pass an argument
5132 to condense_misc_bunches (a zero).
5134 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5135 every time we are called; don't rely on our caller to do it.
5136 (add_file): Remove call to init_misc_bunches.
5138 * mipsread.c: Only warn, don't error, if unknown symbol types.
5139 This keeps an old gdb from falling on its face if it sees newly
5140 extended symbol info. Rename init_misc_bunches.
5142 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5144 * Merge in changes from Per Bothner for DECstations and other
5145 MIPS stuff. The rest is Bothner speaking:
5147 The next message is a merger of Alessando Forin's mips port with
5148 mine. I've tried to use my good if biased judgment to get
5149 the best of both. It *does* need testing.
5151 Some of the changes are general, *not* mips-specific.
5154 Didn't believe in little-endian bit order.
5155 There are still inconsistencies about whether flags
5156 like BITS_BIG_ENDIAN are integer (#if ...) or
5157 boolean (#ifdef ...). I tried to paper over them.
5159 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5160 Moved some misc_function code that was common to
5161 {dbx,coff,mips}read.c to symtab.c.
5162 In the process, I think I cleaned things up a bit.
5163 At the same time, moved obsavestring and obconcat to symtab.c.
5166 Removed obsolete condense_addl_misc_bunches (use
5167 condense_misc_bunches(1) instead).
5170 Needed to include <sys/dir>, at least on DECstations.
5172 valops.c, mips-tdep.c, tm-mips.h:
5173 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5174 conventions (when STACK_ALIGN is insufficient).
5175 Needed on mips, where doubles need 8-byte alignment,
5176 but ints only need 4.
5179 Removed cruft that was not being used.
5180 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5183 Print $ before register-names (I think that makes things a little
5185 Never print two instructions, even if one delays.
5186 Removed hex-disassemble set_cmd. (This is not mips-specific,
5187 so I think the argument is whether it is generally worthwhile or not.
5188 I'm inclined to think not, given how easy it is to
5189 convert between radixes in gdb.)
5192 This is basically Alessando's code.
5193 It doesn't use obstacks; I changed it to use obstacks
5194 in a few minor places where using malloc causes a
5195 memory leak. (Probably, more places could/should be changed.)
5196 I added record_misc_function where it was missing.
5197 In symbol_file_command and add_file_command, I tried
5198 to make the code consistent with more recent versions.
5199 Minor sylistic changes in parse_procedure.
5200 Make a .gdbinfo. psuedo-symbol point back to the real
5201 procedure symbol (using the isym field).
5204 This is basically from my port, but with a lot of details
5205 and a number of routines merged in from Alessando's version.
5206 I basically used my code "raw" backtrace (use heuristics
5207 from the actual code, rather than symbol table info) - though
5208 the idea is Alessandro's. I feel my code is a little cleaner
5209 here, particularly in being a little more flexible, such as being
5210 able to handle gcc-produced code (which it now can).
5211 It also doesn't do frame caching (which is not useful
5212 more recent gdb versions).
5213 I also used my code for push_/pop_dummy, more or less.
5214 I tried to incorporate AF's code for testing sigtramp
5215 while backtracing; I probably got it wrong.
5216 Added mips_print_register, which tries to scrunch as much
5217 information as possible on a screen...
5218 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5219 under mips-pinsn.c), I don't see anything mips-specific here,
5220 and I don't see it being all that useful anyway.
5223 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5224 Use more register names (rather than hard-cases numbers).
5226 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5228 * Hack up 3.90.11 changes:
5230 * Makefile.dist (depend): parameterize $(GCC).
5231 Add solib.c and solib.o.
5232 (readline): Fix vpath for both absolute or relative SRCDIR.
5234 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5235 Also, let the part I didn't understand at least compile so
5236 I can test the rest. FIXME.
5238 * dbxread.c: Fix thinko using strcmp.
5239 (init_psymbol_list): declare static.
5240 (partial_symbol_file_open): Comment cleanups better, avoid
5241 cleaning up the string table since the caller will do that.
5242 Move the stat for mod time into symbol_file_command, temporarily.
5243 (There should be a mod time for each symbol file, eventually,
5244 to control its rereading. FIXME.)
5246 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5247 SunOS, which gives error for shared libs otherwise. (From
5248 Schaefer, probably FIXME needs work for portability.)
5250 * solib.c: Move #include "param.h" to work.
5251 Lowercase all the Uppercase Letters In the Messages.
5252 (find_solib): Clean up inferior_so_name for debug printouts.
5253 Allow no argument, to mean all shared libraries.
5255 * symmisc.c: include param.h to get CLEAR_SOLIB.
5257 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5259 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5260 to 3.90.11. ChangeLog entries below are from this.
5262 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5266 * Makefile.dist (HFILES): Add tm-sunos.h.
5268 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5272 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5274 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5276 * sparc-opcode.h Added single-operand version of rett.
5278 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5280 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5281 Put parens around gcc_p in expansion.
5283 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5285 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5287 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5289 * Changes for Sun shared libraries:
5290 blockframe.c (find_pc_partial_function): If a non-text symbol
5291 is found, set *address = pc - FUNCTION_START_OFFSET.
5292 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5293 Disable breakpoints instead of giving an error.
5294 source.c (select_source_symtab): Initialize cs_pst.
5295 symmisc.c: Call CLEAR_SOLIB if defined.
5296 symtab.h: Make text{low,high} CORE_ADDR not int.
5297 (psymtab): New field addr.
5299 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5300 (record_misc_function): Give correct type for N_DATA symbols.
5301 (condense_misc_bunches): do "misc_function_count = j" regardless
5303 Take code which is shared between symbol_file_command and
5304 add_file_command and put it into partial_symbol_file_{open,read}.
5305 Split add_file_command into add_file_command and add_file.
5306 Make psymtab_to_symtab read in the string table if the file
5308 Two new parameters to read_dbx_symtab and start_psymtab.
5309 tm-sunos.h: New file.
5311 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5313 * infcmd.c: Change cont_command to continue_command and "cont"
5316 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5318 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5320 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5322 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5323 size 1,2,4,8 rather than size < 8.
5325 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5326 as necessary, not just once.
5328 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5330 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5332 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5334 * tm-news.h: Add CALL_DUMMY_*.
5336 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5338 * config.gdb: In list_host, list_target, use ${i}, not $i.
5340 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5342 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5344 * sparc-opcode.h: Change all store floating-point state register
5345 instructions to have the right match & lose fields.
5347 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5349 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5351 config.gdb: If srcdir != ., create readline directory and
5352 copy a makefile into it.
5354 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5355 consistency with POSIX.
5357 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5358 when we exit its exp_valid_block.
5360 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5362 * Makefile.dist: Bump version to 3.91.3.
5364 * Clean up handling of breakpoint commands (somewhat).
5365 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5367 inferior.h: Add breakpoint_proceeded to inferior status struct
5368 and globals; save it and restore it.
5369 (clear_breakpoint_commands): Cleanup, remove old #define.
5371 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5372 (save_inferior_status, restore_inferior_status): handle it also.
5373 (proceed): Remove earlier code that set breakpoint_proceeded.
5374 It is now set only in clear_proceed_status.
5375 (clear_proceed_status): Cleanup, use bpstat_clear rather
5376 than clear_breakpoint_commands. No callers need the stop_bpstat
5377 between clear_proceed_status and proceed.
5379 infcmd.c: Add breakpoint_proceeded definition and comment.
5380 (cont_command, jump_command, signal_command): Move call to
5381 clear_proceed_status right next to call to proceed.
5383 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5384 caller's argument while running down the chain of breakpoints.
5385 Use new variable "breakpoint_proceeded" to determine when
5386 a command that it executes moves the inferior past the
5388 (bpstat_clear): Handle NULL argument.
5389 (bpstat_clear_actions): Avoid useless call to
5390 breakpoint_auto_delete.
5391 (delete_breakpoint): Clean up bpstat's that are pointing to
5392 the deleted breakpoint from the stop_bpstat chain.
5393 (breakpoint_auto_delete): Simplify.
5395 * Clean up handling of EOF, error on stdin, etc. This was
5396 prompted by a network problem that caused gdb to go into an
5397 infinite loop filling up its malloc'd memory.
5399 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5400 not clear_breakpoints_commands, which is now gone.
5401 (main): If command_loop returns (e.g. from EOF on stdin), do
5402 a quit_command (looping back to command_loop if quit_command
5403 doesn't really quit).
5404 (command_loop): check result from command_line_input and
5405 exit if it returns NULL, rather than passing the NULL to
5407 (gdb_readline): Free malloc'd result space before returning
5410 * utils.c (query): Handle C-d to mean "yes", just as if the
5411 input was not a terminal. Also avoid infinite loop if EOF
5412 occurs in mid-input-line before newline. This allows
5413 query to be used at EOF on stdin with reasonable results.
5415 * infrun.c (proceed): Set breakpoint_proceeded.
5417 * values.c (value_as_long): Avoid infinite recursion for enums.
5418 (_initialize_values): Fix typo in help msg (kingdon).
5420 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5421 RL_LIB for linking. This allows -lreadline for linking
5422 and nothing for dependencies, once readline is a real library.
5424 * config.gdb: Jim Kingdon: give useful error message if the
5425 host or target type is not recognized.
5427 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5428 it just defines it. Dumb, but deal with it.
5430 * Jim Kingdon suggests:
5431 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5433 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5435 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5437 * Clean up Bothner's changes.
5439 * blockframe.c (clear_pc_function_cache): New function.
5440 * blockframe.c: remake cache_pc_function_* static.
5441 * dbxread.c (symbol_file_command): remove references to
5442 cache_pc_function_* variables.
5443 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5444 * printcmd.c: Avoid kludging a global variable (addressprint)
5445 to avoid printing the address of a string twice. Instead,
5446 pass the format letter 's' down low enough that it can be seen
5447 to avoid this problem.
5448 (print_formatted): Pass format arg to value_print.
5449 (restore_addressprint): Remove function.
5450 (do_examine): Avoid hacking addressprint, cleanups and such.
5451 (print_frame_args): Add a comment to a Bothner change.
5452 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5453 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5454 to wipe out the values cached in blockframe.c.
5455 * symtab.c (find_method): Add comment saying how big you must
5456 allocate to be "big enough". Per being terse again.
5457 * valprint.c (val_print): Handle format letter "s" to print
5458 strings without addresses. Add comment to vtbl printing code
5459 which casts with wild abandon. Rearrange reference-printing
5461 @0xaddr: value (print w/addressprint)
5462 value (print w/~addressprint)
5463 @0xaddr (parameter lists w/addressprint)
5464 or nothing (parameter lists w/o addressprint)
5466 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5468 * Merge more changes from Per Bothner:
5470 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5471 annoying) that I tried to improve it. Here are my suggestions.
5473 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5476 Do automatic de-reference when taking the address of a reference.
5478 Don't deref_ref when printing parameter lists.
5480 More attempts at treating refernences properly.
5482 In val_print, if deref_ref==0, don't print dangling " = ".
5484 Add COERCE_REF macro, which de-references an REF.
5486 * Merge changes from Per Bothner:
5488 * Fixed (Sony news)-specific configuration problems.
5489 * Fixed other problems with using vanilla pcc and libc (enum problems;
5490 assumption that vsprintf exists).
5491 * Some major speed-ups (finc_pc_partial_function now caches a match;
5492 parsing avoids duplicate symbol_lookup calls).
5493 * Changed handling of baseclasses (no longer use baseclasses field
5494 of struct type, use the first n_baseclasses fields instead).
5495 * Various minor changes/fixes, most C++-related.
5498 Cache the most previous match from find_pc_partial_function.
5499 (Save both low and high ends of matching function's pc range.)
5500 This speeds up the loop of infrun.c:wait_for_inferior quite
5501 a bit, and makes step/next commands much zippier.
5503 Added an enum->int cast (otherwise, some compilers barf).
5505 No longer set baseclass offset to 0, since multiple
5506 inheritance now mostly works.
5507 Added a number of casts, to shut up compiler warnings
5508 (after stabs where made enums, not ints).
5509 When discarding a symbol table (in symbol_file_command),
5510 must clear the cache introduced in blockframe.c.
5511 Don't convert $vtbl_ptr_type to vtbl any more.
5512 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5513 Mask off sign bit emitted by g++ for virtual table offset.
5514 Set voffset to -1 (not 1) for static member functions.
5516 Changed parsing/lexing of names to avoid doing symbol lookup twice
5517 (once when lexing to determine symbol class, once for real).
5518 Now only call symbol_lookup once. Fields of 'this' win especially big.
5520 Subpress printing addr twice in the case of 'x/s addr'.
5522 lookup_basetype_type is no longer used.
5523 Add find_methods as recursive helper function to decode_line_1.
5524 This allows multiple inheritance to work.
5525 Also, once one or more matches has been found, do not look in
5526 base-classes. (Baseclass methods would be overridden, anyway.)
5528 Removed baseclasses array in struct type.
5529 Instead of using baseclasses[i], use fields[i-1].
5530 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5531 Changed sign convention of voffset (previous was inconsistent).
5533 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5535 Used to assume existence of vsprintf. Re-written to not need it
5536 if HAVE_VPRINTF is undefined.
5538 typecmp was too pessimistic. Made it less so.
5540 Don't print space after address.
5541 If vtable points to a misc symbol (with 0 offset), print it,
5542 since that indicates the actual class of the object.
5543 Changed ype_print_derivation_info to use new inheritance
5544 scheme (without baseclasses vector).
5546 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5547 Also, changes needed because TYPE_BASECLASSES were removed.
5549 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5551 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5554 If there is no path set, and the symbols don't indicate what directory
5555 a file was compiled in, look in the current directory. But either
5556 a path or a known compilation directory will prevent this.
5559 Three independent bug fixes:
5560 * Remove the #if 0 block that breaks some stuff.
5561 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5562 adapt gdb to either SunOS 4.0.* or 4.1.
5563 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5566 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5569 (type_print) Demangle the name being printed.
5570 (type_print_base) Handle botched demangling without coredump (tiemann).
5573 (check_stub_method): Document routine.
5574 (tiemann) fix bug for no-arg functions
5575 Avoid clobbering beyond end of malloc'd storage.
5576 Terminate the argument list properly.
5578 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5580 * Changes merged by John Gilmore:
5583 In breakpoint_1, use new print_address_symbolic instead
5584 of find_pc_partial_function. (This forces use of assembler-level
5585 addresses, and avoids misleading non-mangled source-level names.)
5587 Generalize ansi argument such that -1 means skip arglist totally.
5588 Removed global variable print_ansi_qualifiers (which made
5589 code non-reentrant), in favor of extra explicit arguments
5590 to internal routines.
5592 Add new helper function print_address_symbolic.
5593 Use find_pc_misc_function instead of find_pc_partial_function
5594 (since we want assembler-level symbols here).
5596 Print unknown function as just "f (...)", not "f (...) (...)".
5597 Use new fputs_demangled explicitly.
5599 Fixed a typing violation (problem: value.h cannot be imported
5600 without renaming many variable in this file).
5601 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5602 decode_line_1: Moved forward some never-reached code.
5603 Made decode_line_2 skip function prologues correctly.
5605 fputs_filtered should not demangle by default.
5606 Add new fputs_demangled to demangle on demand..
5608 Change value_struct_elt to use value_primitive_field (using recursive
5609 utility function search_struct_field). This allows foo.bar to work
5610 for multiple inheritance (so far only for data fields).
5611 Change check_field in the same way (recursive helper function
5612 to support multiple inheritance).
5613 (Note: there are more of these problems that I haven't fixed.
5614 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5615 value_of_this: 'this' symbol name is now just "this", note "$this".
5617 Don't print static members.
5618 Avoid printing "members of <type>" if there are none.
5619 Simplified type_print_derivation_info by merging duplicate code.
5620 Remove useless blank lines in type_print_base (ptype command).
5622 Added declaration of new routine value_primitive_field.
5624 Added value_primitive_field which is generalized version of
5625 value_field that can handle multiple inheritance (non-zero offsets etc).
5626 Re-implemented value_field to call value_primitive_field.
5628 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
5630 * infcmd.c -- insert else to avoid 'delete env' coredump when you
5631 delete the whole environment. Karl Berry reported the bug.
5632 * source.c - fix openp to avoid //'s in filenames, which
5633 trigger an Emacs bug causing it to not be able to find files
5634 when running gdb in a window.
5635 * dbxread.c - zap the #if 0 that botches the add-file code.
5636 It seems to work a lot better without all the code commented out.
5638 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
5640 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
5643 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
5645 * Makefile - added a ${CFLAGS} to a couple of entries,
5646 added remote-sa.sparc.c
5647 * added remote.sa-sparc.c, a modification of remote.c
5648 which conducts a dialog directly with the SparcStation prom.
5649 * breakpoint.c, infrun.c, sparcdep.c added
5650 remote_insert_breakpoint(), and remote_remove_breakpoint()
5651 to breakpoint.c instead of directly writing breakpoint instructions.
5652 * sparcdep.c on remote_debugging,there is no need
5653 to remove signle step breakpoint instructions.
5654 * main.c added "-epoch" flag and "int epoch_interface" to main.c
5656 * printcmd.c - epoch interface sends lisp expressions to open up
5657 epoch windows on inspection.
5658 * valprint.c - added arrayprint, and addressprint and made adding
5659 format controls easier
5660 * wait.h added a couple of undef's because we were getting
5661 complaints about WSTOPSIG and WTERMSIG begin redefined.

5731 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
5732 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME

5757 step_resume_break_address != NULL, even if another_trap.
5758 If trap_expected and we enter sigtramp, then set up a
