1 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
3 * doc/refcard.tex (sec "Working Files"): consistent metavars, due
4 to Franc,ois Pinard (pinard@iro.umontreal.ca)
6 * doc/gdb.texinfo (appendix "Installing GDB"): changes in configure.
8 Tue Oct 15 08:45:12 1991 John Gilmore (gnu at cygnus.com)
10 Changes from Fred Fish:
11 * tm-68k.h (FPI_REGNUM): Add.

15 * inflow.c: Handle TIOCGLTC_BROKEN for Amiga.
18 * values.c (show_convenience): Use printf_filtered.
19 * main.c (define_command): Check result of lookup_command for
21 (echo_command): Use printf_filtered, and force output out.
23 * dbxread.c (read_enum_type): Avoid Modula-2 kludge that breaks C
25 * i387-tdep.c (double_to_i387): Fix typo for double_to_ieee_extended.
26 * utils.c (_initialize_utils): If !ISATTY, don't paginate.
27 * configure.in, tconfig/decstation, xconfig/decstation: Rename
28 dec3100 to decstation.
30 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)
32 * doc/gdb.texinfo: Catch up to changes recorded here in ChangeLog
33 (nodes Continuing and Stepping; Memory; Targets) clarifications
36 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
38 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move
39 REGISTER_U_ADDR to corresponding xm- file. Sugg. by Peter Schauer.
41 * symmisc.c (print_partial_symtabs): Add printpsyms debug cmd.
43 * m68k-tdep.c (m68k_push_dummy_frame, m68k_pop_frame): Add
44 generic routines for calling inferior functions.
46 * blockframe.c (inside_main_scope, inside_entry_scope): New.
48 * copying.awk: Filter formfeeds out of copying & warrantee.
49 Make them available as `show copying' and `show warrantee' also.
50 * main.c (print_gnu_advertisement): Advt `show' commands.
52 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)
54 * mach386-xdep.c: Even when cross-compiling, leave in the
55 core-file reading code.
56 * core.c (get_core_registers): Avoid coredump if no .reg section.
58 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
60 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
61 This avoids coredumps under `set print object on' in value_headof
62 (called erroneously by value_from_vtable_info) for `p &struct'
63 or `p *struct'. From Peter Schauer.
65 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
67 * Makefile.in: Roll version to 4.1.2.
68 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
69 size from BFD (but, FIXME, we don't yet read external nlists's and
70 convert them to internal nlists's before handling them -- we still
71 assume they have the same size and alignment.) Use SET_NAMESTRING
73 * exec.c (exec_file_command): Move dead coff-encapsulation code
75 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.

79 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
80 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
82 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
84 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
85 * mips-xdep.c (store_inferior_registers): Don't try to
86 write the (pseudo) FP.
87 * mipsread.c (parse_partial_symbols): Improved algorithm for
88 setting pst->texthigh.
90 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
92 * doc/Makefile: make TEXINPUTS include . everywhere
94 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
96 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
97 vestiges of typevectors, which were for symsegs and are no longer
98 used. (From a question by Eliot Dresselhaus
99 <dresselh@RFT30.nas.nasa.gov>).
101 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
103 * dbxread.c, coffread.c: static-ize functions that were
104 gratuitiously external. (From Fred Fish.)
106 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
108 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
109 until it is large enough.
111 * dbxread.c (read_type): Handle error case slightly better.
112 Make complaint message not C++-specific.
114 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
116 * infrun.c (wait_for_inferior): Fix step/next so that you only
117 stop at the beginning of a new line. This fixes various problems
118 with for loops, nested if-else's and switch statements.
120 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
122 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
123 between symtabs and psymtabs become ordinary error()s.
125 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
126 properly, making "end pc" correct in shared lib psymtabs.
127 (From Guy Harris <guy@auspex.com>.)
129 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
131 * dbxread.c: Enable, but soften, const_vol_complaint.
132 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
133 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
134 should be file-scope, not global.
135 (read_struct_type): Remove ancient multiple-inheritance warning.
136 (read_range_type): Check base type, complain & patch if undefined.
137 * stack.c (frame_info): Demangle the function name in `info stack'.
140 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
142 * eval.c (evaluate_subexp_for_address): Don't use
143 TYPE_POINTER_TYPE directly (it might be zero if this type has
144 never had a pointer created before); use lookup_pointer_type.
145 * symtab.c (lookup_method_type): Arguments were swapped in all
146 callers, so fix it here. I'm amazed this worked at all!
148 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
150 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
151 "bss" rather than "data" symbols, but which still conflict.
154 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
155 * core.c (core_files_info): Shorten output.
156 * exec.c (exec_files_info): Ditto.
157 (build_section_table): Ignore zero-length sections.
158 * language.c, printcmd.c: Lint.
159 * language.h (get_frame_language): Declare.
160 * saber.suppress: update.
161 * stack.c (find_relative_frame): Remove complex code that was
162 #if 0'd, stick with simple code. Lint.
163 * saber.suppress: Update a bit.
164 * symfile.c (add_symbol_file_command): Add "?" to question.
165 * utils.c (parse_escape): Avoid \a due to bdead compilers.
166 * value.h: Declare typedef_print.
168 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
171 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
172 (Reported by Mark Peek <mark@imagen.com>.)
174 * solib.c (solib_map_sections): Relocate all sections, even
175 though only the text section's size is tracked. Mark ld_text
176 for eventual elimination as we generalize to N sections.
178 * infrun.c (wait_for_inferior): Don't check if the PC is in a
179 call_dummy if we were stopped by a random signal that is being
180 passed to the program. This produced wierd results when calling
181 functions in the inferior and signals (e.g. SIGALRM) were in use.
183 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
185 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
186 Bugfix from Paul Eggert <eggert@twinsun.com>.
187 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
188 * valprint.c (print_floating): Print 9 digits for IEEE floats.

201 * Makefile.in (VERSION): Set to 4.1.
202 * language.c (set_language_command): Print useful help message,
203 and restore the language string after giving help.
204 * valprint.c (typedef_print): Print typedef in C or M2.
205 * symtab.c (list_symbols): Use it.
206 * main.c (main): Avoid any output before (gdb) prompt when -q.
207 * language.c (set_language_command): Handle errors by restoring
208 the language string to its current state (fix from A. Beers).
209 * doc/gdbint.texinfo: Roll in information from README. Rearrange
210 "how to install" and "how to print the doc" stuff so it drops
212 * configure.in: Rename rtpc CPU to romp to match config.sub.
213 * README, WHATS.NEW, TODO: Update for gdb-4.1.
215 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
217 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
218 autoloading shared libs, copyright etc on GDB startup, clean up $_
219 and $__ index refs, set/show listsize and related updates to list
220 cmd. New host/target configs.
222 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
224 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
225 from main Makefile.in version definition
226 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
228 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
230 * doc/gdb.texinfo: merge new language-switching and lang-specific
233 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
235 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
236 compilers (which may lack stddef.h).
238 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
240 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
241 N_WARNING are the same except for the N_EXT bit, so just use their
242 values alone, rather than OR-ing them with N_EXT.
244 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
246 * mipsread.c (parse_lines): Deal with negative extended line
249 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
250 global symbol conflicts.
252 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
254 * .gdbinit: Move 'set complaints' to top, so it runs even in
255 case we aren't debugging GDB.
256 * language.c (_initialize_language): Fix type check and range
257 check documentation strings.
258 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
259 language.c can use it. (Though language.c should really not be
260 handling warnings/errors the way it does, FIXME.)
261 * symtab.c (lookup_primitive_type): const lint.
263 Bugfix from Peter Schauer:
264 * source.c (lines_to_list): Make signed, to avoid comparison
265 going unsigned and complaining that -3 is too high for 21 lines.
266 * stack.c (lines_to_list): Ditto.
268 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
270 * Makefile.in (HFILES): Add minimon.h.
271 (VERSION): Roll version number to 4.0.95.
272 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
273 New rules for building distributions. Normal distribution
274 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
275 one level up from here; it calls make-proto-gdb.dir to build a
276 directory `proto-gdb' which is an image of the release. The old
277 `gdb.tar.Z' rule still works too.
278 * config.sub, configure: Roll in latest from ..
280 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
282 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
283 new-target, and new-config chapters; fix minor typos; come closer
284 to usual GNU markup conventions for @file @samp @code @var.
286 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
288 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
289 * mipsread.c (parse_partial_symbols): Enter the name of all
290 structs/unions... into the psymtab so we can access them if the
291 symtab is not read in.
292 * mips-tdep.c: Remove some unneeded #includes.
293 * xconfig/dec3100: Add HAVE_STRSTR.
295 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
297 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
298 * c-exp.y, m2-exp.y: Lint.

300 * valprint.c (val_print_fields): Check for stub type.
301 * mipsread.c (_initialize_mipsread): Avoid using
302 builtin_type_void at initialize time.

305 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
307 Merge multiple-language support, and partial Modula-2 support,
308 from Andrew Beers <beers@cs.buffalo.edu>.
310 * i387-tdep.c: New file, consolidates most 80387 support,
311 and eliminates host dependency on double<->extended conversions.
312 * i386-xdep.c, symm-xdep.c: Remove most 387 support.

404 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
406 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
407 entries are enclosed herein. Not all of these changes
408 have been merged into the master GDB sources -- check the
409 ChangeLog above here for the merge log.
411 Mon Jun 3 17:05:45 EDT 1991
413 m2-exp.y Created. Tested outside of GDB for a few days. Proper
414 operators were added, C specific operators and tokens
415 removed. yylex() revamped to some extent. Still things
416 missing from the grammar, such as sets.
417 Tested for two weeks in GDB v3.5.
419 Tue Jun 11 17:23:48 EDT 1991
421 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
422 so they are built-in. Sort of a hack.
424 Fri Jun 14 12:53:51 EDT 1991
426 m2-exp.y Added range checking for numeric constants. Any numeric
427 constant is assumed to be of builtin type INTEGER unless:
428 (1) it is octal or hexadecimal, in which case it is a
429 CARDINAL; (2) it is too big to fit into an INTEGER, in
430 which case it is a CARDINAL.
431 eval.c Added simple range checking for +, -, and * on integers.
432 Doesn't work very well for *, since 6 * 1,000,000,000 =
433 1,705,032,704, which fails the simple test of result >=
434 first_operand, no matter in what order the operands are.
436 Tue Jun 18 14:11:30 EDT 1991
438 Broke the parser into parts, one containing the C grammar and the other
439 containing code to be shared by all of the grammars.
441 The following files no longer exist:
446 The following files were added:
448 c-exp.y (The C grammar)
449 m2-exp.y (The Modula-2 grammar)
450 parser-code.c (Code that is shared by the above grammar)
454 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
455 now necessary to use the Bison compiler compiler, since it
456 will generate function/variable prefixes other than yy.
458 Tue Jun 18 16:47:49 EDT 1991
460 symtab.[ch] Added the external variable working_lang, than holds the
461 value of the current working language.
462 Added the ennumerated type language_mode, with the values
463 language_auto and language_manual, the former meaning that
464 GDB sets working_lang as needed, and the latter meaning
465 that the value of working_lang is totally under user
467 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
468 REAL, BOOLEAN and CHAR. Also added the type codes
469 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
470 utils.c Added set_language_command and show_language_command to
471 implement the GDB support commands "set language" and
473 expression.h A number of identifiers were added to the type exp_opcode
474 to facilitate Modula-2 builtin functions, integer
475 division, and array indexing.
477 Wed Jun 19 13:25:58 EDT 1991
479 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
480 if the language specified by working_lang requires the use
481 of strict typing of expressions. Eventually, even this
482 will be able to be changed by the user.
483 Added the macro RANGE_CHECK, which evaluates to non-zero
484 if the language specified by working_lang requires the
485 checking of a value against the domain of its type.
486 Eventually, even this will be able to be changed by the
488 language.[ch] Predicates involving types (simple_type, ordered_type,
489 same_type, integral_type, numeric_type, character_type,
490 boolean_type, float_type) are added. These predicates are
491 based on the current value of working_lang, and are handy
494 Wed Jun 19 15:39:34 EDT 1991
496 eval.c Added the function type_array_rank which computes the rank
498 valarith.c Added the funtion value_bool, which when given a integer
499 value.h value (ie. struct value *) as an argument, it returns a
500 boolean value (ie. struct value *) true if that integer
501 is non-zero, and a boolean value false otherwise.
502 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
503 will print out properly.
505 Wed Jun 19 16:36:34 EDT 1991
507 valops.c Added the function value_capitalize, which returns it
508 value.h argument capitalized if its argument is a lowercase
509 letter, or the argument unchanged if its argument is not a
511 valarith.c Added the function range_check_p, which returns non-zero
512 value.h if its value argument is between the integral bounds upper
514 Added the function range_check_enum_p, which makes sure
515 that its value argument is a valid member of the domain of
517 Added the function range_check_range_p, which makes sure
518 its value argument lies between the upper and lower bounds
519 of its type argument, which must be a ranged type.
520 Added the function check_array_index, which range and type
521 checks an index of an array.
522 Added the function value_multi_subscript, which computes
523 array[idx1,idx2...idxN], given a value array and an array
524 of values representing indicies.
525 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
526 unpack_long to work with TYPE_CODE_BOOL and
529 Wed Jun 19 18:04:08 EDT 1991
531 symtab.c Stored pervasive types in a structure and make
532 lookup_pervasive_type() a lookup function that was based
533 on working_lang. If lookup_pervasive_type() returned
534 non-zero, then that value was returned (a fix, since
535 before it simply wouldn't return the pervasive type.)
536 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
537 non-zero if the language specified by working_lang means
538 "conversion" when it says "cast".
539 valops.c Added the function value_real_cast(), which performs a
540 value.h *cast*, not a *conversion*, which is what value_cast()
541 does when it can. In particular,
542 value_cast(<float_type>,4) = 4.0, while
543 value_real_cast(<float_type>,4) = some mess.
544 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
545 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
546 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
547 and MIN on integral types. *NOTE*: These are currently
548 hardcoded to work only if there are 8 bits per storage
550 eval.c Made logical functions call value_bool to return a
551 properly typed boolean value, based on working_lang.
553 Thu Jun 20 11:55:27 EDT 1991
555 valprint.c Types now print out in a Modula-2 fashion. This works for
556 the cases when the type is printed out step-by-step, that
557 is, it doesn't work when the name of a structured type
558 (which includes the keyword "struct", etc.) is simply
560 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
561 since type specifications in C and Modula-2 are very
562 different. The C printing of a type is very recursive,
563 whereas in Modula-2 it is generally very simple. C has
564 type prefixes and suffixes, which have no real analogue in
565 Modula-2. Maybe type_print() should call a language
566 specific type printer. This is also advantageous if we
567 compile GDB to exclude some of the languages. We'll just
568 leave those functions out.
570 Thu Jun 20 16:57:10 EDT 1991
572 dbxread.c When reading the complete symbol table in (via
573 psymtab_to_symtab()), the number and types of function
574 arguments are added to a function type. define_symbol()
575 calls add_param_to_type() to accomplish this.
576 Assumption: when we come across a function definition
577 (N_FUN symbol with an 'f' or 'F' in the name), its
578 arguments will appear before another function definition.
579 When a function is found, a pointer to its type is placed
580 in the global in_function_type. Changes that
581 add_param_to_type() makes are to this global.
582 valprint.c The type of a function now includes (for Modula-2) the
583 types of its parameters.
584 eval.c Type checking and a check for the proper number of
585 arguments is now done for function calls. Not sure of the
586 impact this has on C++ member function yet.
588 Thu Jun 20 19:58:48 EDT 1991
590 valprint.c Rewrote the type printer. Broke it into two language
591 specific parts, adding the functions type_print_m2() and
593 An unfortunate consequence is this: if you debugging a C
594 program in Modula-2 mode (why?), info types does not work
595 well with regular expressions, since the types are printed
596 out in Modula-2 terminology, but stored in C terminology.
597 language.[ch] Added the functions new_type_last(), type_keyword(), and
598 type_sep() to aid in the printing of typedefs.
599 symtab.c Made the printing of typedefs as language independent as
600 possible through calls to new_type_last(), type_keyword(),
603 Fri Jun 21 11:50:26 EDT 1991
605 dbxread.c Check all incoming ennumerated types. If it looks like
606 Modula-2's BOOLEAN type, then change the type_code of the
607 type to TYPE_CODE_BOOL so we can process it as a boolean
609 valprint.c Replaced some of the 0x%x with calls to sprintf and
610 hexformat() in val_print().
611 language.[ch] Added the function hex_to_string(), which converts its
612 integral argument to a hexadecimal number (format is
613 language based) and returns the result as a string.
615 Mon Jun 24 12:25:07 EDT 1991
617 valprint.c Some functions call type_print_1() directly, instead of
618 value.h using type_print(), so they can specify where (column) to
619 print things. Since type_print() takes care of language
620 dependence, that needs to be called first. Added a
621 parameter depth to type_print() (so it is now like
622 type_print_1). Changed type_print to type_print_at, and
623 made type_print a macro that passes a depth argument of
625 symmisc.c Changed all calls to type_print_1 to calls to
627 Makefile.dist Made it possible to build GDB for a specific set of
628 depend languages. Do this by passing a definition for the macro
629 LANGS to make. LANGS should be a string containing a
630 space-separated list of language names (ie. LANGS="c m2").
631 The default is to build all languages. Note that grammar
632 files must follow the naming convention of <lang>-exp.y.
633 gdb.lang This holds the current value of the LANGS macro. It is
634 examined every time make is called, and is updated if
636 eval.c Added #ifdef _LANG_<lang> to these files.
637 expread.c Still need to add them to dbxread.c and coffread.c.
645 Mon Jun 24 16:33:11 EDT 1991
647 language.[ch] Added the functions hexformat_pre() and
648 hex_to_string_pre(), which take a prefix argument to
649 include in the format string. Thus, hexformat_pre("08") will
650 return "0x08x" (if the working language is language_c).
651 Made hexformat() and hex_to_string() calls to the above
652 with "" as the prefix argument.
654 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
655 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
656 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
657 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
658 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
659 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
660 valprint.c, vax-pinsn.c
662 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
663 calls to hexformat() and hex_to_string(). Format strings without
664 the leading "0x" were ignored.
666 depend Updated to take the above into account.
669 Tue Jun 25 15:27:18 EDT 1991
671 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
672 and type_check_t to keep track of the current state of
673 range and type checking.
674 main.c Added the variables range_mode, range_check, type_mode,
675 and type_check to record the current state of range and
676 type checking. Added initialization code to main().
677 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
681 Tue Jun 25 17:57:08 EDT 1991
683 dbxread.c process_one_symbol() updates the variable (enum language)
684 source_lang based on the extension of the filename
685 contained in the N_SO sybmol that started this symtab.
686 When end_symtab() is called, the value of source_lang is
687 put into the language field.
688 stack.c select_frame() sets working_lang (and possibly type_check
689 and range_check) to the language field of the symtab
690 associated with the frame that is selected if working_mode
691 is language_auto. If working_mode is language_manual, a
692 warning is printed and working_lang is not set.
693 language.c Added the function set_type_range(), which sets the value of
694 type_check and range_check (if their modes call for
695 automatic setting) based on the current value of
696 working_lang. A non-zero argument will cause the current
697 settings to be output.
700 Wed Jun 26 14:51:40 EDT 1991
702 eval.c Added range checks on assignment.
703 m2-exp.y Added the grammar for sets to the language. Currently,
704 these do not do anything except print an error message.
706 Wed Jun 26 17:01:04 EDT 1991
708 m2-exp.y Added the ability for parse_number() to parse negative
709 numbers. A global flag is set upon encountering a unary
710 minus. This was done to make, for example, 1 parse as a
711 CARDINAL, and not as an integer, per Wirth's examples in
712 Programming in Modula-2 ed.4.
713 valprint.c Added support for "set radix 2" by then setting
714 output_format to 't'.
715 eval.c Implemented range checking on subrange types. Added calls
716 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
717 Implemented MIN and MAX for ennumerated types. The
718 minimum value of an ennumerated type is defined by Wirth
719 as the first identifier, and the maximum as the last.
720 m2-exp.y Made octal numbers ending with "B" be characters and those
721 ending with "C" be numbers, per Wirth's book. (p. 34)
723 Thu Jun 27 14:11:52 EDT 1991
725 stack.c select_frame() now only sets working_lang, it does not
726 notify the user. If working_mode is language_manual, then
727 a warning is issued once.
728 main.c At the end of each call to execute_command(), working_lang
729 is checked against the local static (enum language)
730 current. If they differ and working_mode is
731 language_auto, the new settings of language, type and
732 range checking are printed out.
733 stack.c Modified frame_info() to include the language of the
734 current frame in the output of "info frame".
735 language.[ch] Added the function language_str() which returns the name
736 of the current language.
738 Fri Jun 28 15:33:14 EDT 1991
740 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
741 the language. INCL and DECL currently cause an error,
742 since sets are not implemented yet. INC and DEC are
743 implemented as PREINCREMENT/PREDECREMENT with one
744 argument, and as ASSIGN_MODIFY with two arguments.
745 eval.c Added type checking to the above cases.
746 value.h Added not_lval_constant to the lval_type ennumerated type.
747 not_lval_constant means that the value is a constant
748 value; that is 3 or 'a' or TRUE, not as in a constant
749 identifier. This is used to help coerce numbers such as 3
750 to either signed or unsigned numbers.
751 valops.c Added the function value_coerce_constants() which coerces
752 constant integers as following: if one is a constant and
753 the other is not, the constant's type is set to the type
754 of the other argument. If both are constants and one is
755 signed, the other is converted to a signed constant.
757 Sat Jun 29 17:26:29 EDT 1991
759 valarith.c Added a better range checker. It now checks range
760 (successfully) on integral operations [+-] (signed and
761 unsigned) for any C sized type. Still does not work well
763 int_in_size() returns an integer that is coerced to fit into
764 specified number of bytes.
766 Mon Jul 1 13:04:14 EDT 1991
768 language.[ch] Added the function binop_result_type(), which returns the
769 builtin (struct type *) type that would be the result of a
770 binop on the two values V1 and V2.
772 Wed Jul 3 19:22:53 EDT 1991
774 source.c Extended source_info() to include the source language in
775 the output from "info source".
777 Fri Jul 5 13:48:52 EDT 1991
779 utils.c Moved the support functions for the GDB set/show commands
780 dealing with language into language.c.
781 language.c Added the function language_info(), which displays info
782 about the current working language, type and range check
783 settings. Called via the GDB command "info language".
784 Added an initialization routine _initialize_language(),
785 that sets defaults for the language, type and range
786 variables and sets up the new GDB commands.
787 main.c Language setup moved to language.c.
790 Mon Jul 8 10:10:22 EDT 1991
792 valarith.c Debugged the range checker for arithmetic. Still does not
793 work for multiplication very well.
795 Mon Jul 8 12:40:37 EDT 1991
797 language.[ch] Added the function value_true() which returns non-zero if
798 its argument represents a boolean true value.
799 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
800 check the truth of an expression.
802 Thu Jul 11 12:51:34 EDT 1991
804 language.[ch] Added the predicate structured_type(), which returns
805 non-zero if the argument is a structured type.
806 Added the predicate pointer_type(), which returns non-zero
807 if the argument is a pointer type.
808 eval.c Added the ability to do addition and substraction on
809 pointers and integers. This case simply bypasses the
812 Thu Jul 11 14:41:42 EDT 1991
815 Added the symbol N_DEFD (0x4a) which is a definition
816 module dependency that is used by the GNU Modula-2
817 compiler and the linker. It is not important to GDB,
818 except that [dbx|coff|mips]read.c should ignore these
821 Fri Jul 12 16:07:00 EDT 1991
823 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
824 0 in val_print(). Also added statements to the else part
825 to coerce type (argument to val_print) to a pointer type
826 if it is an "array of unspecified length".
827 valops.c Added the function value_m2_string(), which returns a
828 (value) value which is a constant string, whose type is
829 (ARRAY [0..n] OF CHAR). The length field of the type
830 structure is set to zero, so it will be interpreted as an
831 "array of unspecified length".
832 stack.c Moved the language/frame mismatch check to
833 main.c:execute_command().
834 main.c The working language is recorded each time
835 execute_command() is executed. If working lang has
836 changed during its execution, then the new
837 language/type/range info is printed out for the user. If
838 the working language does not match the language of the
839 frame, a warning is issued.
841 Sat Jul 13 16:16:39 EDT 1991
843 eval.c Moved all the type-checking stuff for operators to
844 language.[ch] language.c. This is so we can keep language-specific
845 stuff (like for what type operators are defined) in
847 language.[ch] Added the function binop_type_check(), which checks to see
848 if its two (value) arguments are type-compatible with its
849 opcode argument. The opcode should represent an operation
850 involving an operator. Also added the macro function
851 unop_type_check, which calls binop_type_check with a
852 NULL second argument.
853 expprint.c Added Modula-2 operators to the op_print_tab, so info
854 expression.h break works correctly. Also added "op_string", which
855 returns the string corresponding to the (enum exp_opcode)
856 opcode that is its argument.
859 Sat Jul 13 18:26:18 EDT 1991
861 coffread.c Added code to record the type of function arguments with
862 each paricular function. Code is very similar to that
864 dbxread.c Moved add_param_to_type() to symtab.c
865 symtab.[ch] Added function add_param_to_type() from dbxread.c
867 *** NOTE: The above additions have not been tested.
869 Mon Jul 15 12:50:47 EDT 1991
871 langauge.[ch] Added the functions type_error and range_error, which work
872 like error() except if the type/range mode is set to
873 *_mode_warn, then they do not do a return_to_top_level(),
874 but merely print a warning.
875 Also changed [set|show]_[type|range]_command() to support
876 the new "warn" feature.
878 Thu Jul 18 17:50:54 EDT 1991
880 mipsread.c Added code to record the type of function arguments with
881 each particular function. Code is very similar to that
884 *** NOTE: The above additions have not been tested.
886 Fri Jul 19 11:19:10 EDT 1991
888 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
889 UMIN_OF_SIZE, which when given a size of a numeric type,
890 return the maximum and minimum value it can hold. UMAX...
891 and UMIN... return the result for unsigned types.
892 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
893 struct types. They call above macros.
894 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
895 avoid a name conlict with the above.
896 c-exp.y Added range checking on numeric constants in
897 parse_number() for completeness.
898 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
899 return 0 if working_lang is not language_c.
901 Thu Aug 8 14:17:22 EDT 1991
905 breakpoint.c Documentation strings of some commands changed to
906 eliminate the references to the C language where
909 Tue Aug 13 15:48:03 EDT 1991
911 m2-exp.y Added qualified identifiers to the grammar. The semantics
912 are slightly different from those of the GDB operator ::
914 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
915 type_exp, where type_exp is any valid type expression.
917 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
918 printcmd.c Modified ptype_command() so it actually parses the input
919 (necessary for type expressions with scope qualifiers).
920 Added the function ptype_eval() which expects an
921 expression composed of one OP_TYPE element.
922 *.[ch] Replaced all occurences of parse_c_expression with
924 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
926 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
928 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
930 Small fixes from Peter Schauer:
932 * infrun.c (child_attach): Lint.
933 * solib.c (find_solib): Handle shared libs version 2.
935 Small fixes from David Wood:
937 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
941 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
942 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
944 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
945 chars_per_line is at maximum (user typed `set width 0'). Fix
946 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
948 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
950 * coredep.c: include ptrace.h where necessary.
951 * mipsread.c(parse_lines): fix unsigned char problem that was
952 messing up line numbers on SGI's and possibly other MIPS based
954 * infrun.c (child_create_inferior): use better test to check
955 return val from setpgrp().
956 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
957 for sgi/irix support.
959 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
961 * mipsread.c (parse_symbol): Put non-static procedures
964 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
966 Patch together `text_start' and `text_end' for 29K port.
968 * exec.c (exec_command): If NEED_TEXT_START_END, define the
969 variables and set them based on the exec file.
970 * am29k-tdep.c: declare text_start.
971 * valops.c (call_function_by_hand): declare text_end.
973 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
974 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
975 because machines that do this will also have to know to
976 set NEED_TEXT_START_END. Besides, it was a redundant way to
978 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
979 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
982 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
984 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
986 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
987 Pass MUNCH_DEFINE to munch whenever we run it.
988 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
989 format string; use 0x%x instead.
990 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
991 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
992 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
993 * inflow.c: Handle `short' process group IDs.
994 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
995 and check for ptrace errors.
996 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
997 (coff_symfile_init): Initialize text_bfd_scnum.
998 (read_coff_symtab): Use it to find the text [and absolute?] sections.
999 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1000 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1001 Merge target arm case with other "easy" cases. Add target
1002 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1003 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1005 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1006 * munch: Cope with RT/PC putting fns in data segment.
1007 Restore ability to override `nm' by specifying MUNCH_NM.
1008 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1009 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1010 and remote-adapt. Remove encapsulated coff #define's (the
1011 support should go in BFD, and gdb shouldn't know or care).
1012 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1013 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1014 * tm-29k.h: Update BADMAG (though it should go away).
1015 Allow the register definitions to be overridden in another
1016 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1017 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1018 DUMMY_SAVE_GR96, for handling kernel calling conventions
1019 that use GR64+ rather than GR96+.
1020 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1021 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1022 overrides various things.
1024 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1025 child_attach does, making a clean stop in the newly attached
1027 * remote-eb.c: Lint.
1029 * coffread.c: Make coffread independent of any particular
1030 variant of COFF. Avoid #include-ing any particular one except
1031 internalcoff.h. BFD now passes key values for symbol reading
1032 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1033 and the symbol masks and shifts); use them.
1034 Remove obsolete end_of_text_addr.
1036 * exec.c: Remove unused include files.
1038 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1040 * Makefile.in (documentation targets): Pass $(M4).
1041 Bugfix from eggert@twinsun.com (Paul Eggert).
1043 * stack.c (down_silently_command): Check for stack existence.
1045 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1047 * Makefile.in (VERSION): Update to 4.0.3.
1049 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1051 * core.c (core_file_command): Print frame at coredump with
1052 its level number, by calling print_stack_frame.
1053 * frame.h: Add selected_frame_level, print_stack_frame.
1054 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1055 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1056 Change print_sel_frame and print_selected_frame callers to
1059 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1060 * symfile.c (free_named_symtabs): Ditto.
1061 * main.c (main): wrap_here needs an arg.
1062 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1063 (solib_add): Avoid noise.
1064 (solib_create_inferior_hook): Lint.
1065 (sharedlibrary_command): Move dont_repeat to here.
1066 * utils.c (error): Call wrap_here to force buffered output.
1068 Small patches from Peter Schauer:
1070 * coffread.c (start_symtab): Free any existing line_vector before
1072 (read_coff_symtab): Ditto for type_vector.
1074 * source.c (lines_to_list): New variable, replacing function.
1075 (all uses): Use as variable.
1076 (_initialize_source): Add 'set listsize' and 'show listsize'.
1077 * utils.c (lines_to_list): Remove function.
1078 * stack.c (print_frame_info): Use as variable.
1079 * defs.h (lines_to_list): Remove declaration.
1081 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1083 * breakpoint.c (insert_breakpoints): Restore warning about
1084 the program might be running in another process, but only for
1085 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1086 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1088 * utils.c (error): if error_pre_print is set, print the string
1090 * main.c (main, print_gnu_advertisement, print_gdb_version):
1091 Reformat legalese so it always prints, but acts as an "I'm here"
1092 message while symbols are being read. If any errors occur,
1093 print a few newlines to set off the message and start it at the
1094 left margin. Remove mention of "help" command, and don't yak
1095 about symbol reading.
1096 (catch_errors): Error string is now printed first in case of
1098 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1099 suggest the "help" command.
1101 * Makefile.in (VERSION): Set to 4.0.2.
1103 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1105 * .gdbinit: Remove useless "rr" command. Set complaints
1106 to 1 for people debugging gdb.
1108 * breakpoint.c, remote-vx.c: Reword strings printed by
1109 catch_errors callers.
1111 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1113 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1114 (Fix from kenc@viewlogic.com.)
1116 Fix some infrastructure to be able to cope with host and target
1117 machines with different sized basic types (ints, ptrs, etc).
1118 (Idea from pierre@la.tce.com (Pierre Willard).)
1120 * values.c (value_from_longest): Rename from value_from_long.
1121 Handle pointer types as well as integers, so that targets with
1122 different pointer sizes from the host can be accomodated.
1123 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1124 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1125 uses of value_from_long to value_from_longest.
1126 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1127 the correct pointer type to value_from_long{est}.
1129 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1131 * remote-vx.c: Remove obsolete code for calling functions via
1132 vxworks kludge interface (it referenced value_from_long).
1134 * valops.c (value_string): Find malloc with lookup_misc_func, not
1137 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1139 Make writing to files work properly. (Fixes to BFD are also needed.)
1141 * core.c (core_open): Open file ourselves, read or r/w, depending on
1142 write_files. Use bfd_fdopenr.
1143 * gdbcore.h (write_files): New variable.
1144 * exec.c (write_files): Define variable, add set&show for it.
1145 (exec_file_command): Use write_files to open for read or r/write.
1147 Make shared library reading happen automatically. These changes
1148 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1150 * inferior.h (stop_soon_quietly): Add to exported variables.
1151 * infrun.c (child_create_inferior): call solib hook, if defined.
1152 (child_attach): call solib hook, if defined.
1153 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1154 (find_solib): Use lookup_misc_func rather than hand-rolled.
1155 (symbol_add_stub): New stub for catch_errors.
1156 (solib_add): Avoid output if !from_tty. Catch errors rather
1157 than just calling symbol_file_add and bombing.
1158 (solib_create_inferior_hook): Interface with the target process
1159 to let it read and alloc shared libs, then figure out what it did.
1161 * core.c (validate_files): Fix typo, soften warning.
1162 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1164 * utils.c (fputs_demangled): Avoid duplicate printing if
1165 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1167 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1168 (Fix from pierre@la.tce.com (Pierre Willard).)
1170 * main.c (catch_errors): Change argument to a char * from an int,
1171 since a char * can point to a struct full of glop, but an int
1172 is not guaranteed to be able to hold a pointer.
1173 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1174 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1175 * core.c (core_open, solib_add_stub): Adapt.
1176 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1178 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1180 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1181 by adding .NOEXPORT target.
1183 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1187 * Makefile.in (VERSION): Roll to 4.0.
1188 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1190 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1192 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1195 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1198 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1200 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1201 reflect above name change
1203 * WHATS.NEW: correct pointer to refcard.
1205 * doc/gdb.texinfo: update New Features, Installing
1207 * doc/gdbint.texinfo: add short description of configure +template
1209 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1211 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1213 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1215 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1216 tar file, add dependencies for referenced doc files.
1218 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1220 * coffread.c, symfile.c, stack.c: saberized.
1222 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1224 * doc/refcard.tex: permuted Essential Commands sec
1226 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1228 set/show symbol-reloading
1229 default set complaints 0
1231 RET-repeat disabled after prompted long displays
1232 processID (attach) interpretation of 2nd GDB cmdline arg
1234 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1236 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1237 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1238 breakpoint.c, main.c: lint.
1240 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1242 Install new configuration scheme for GDB and friends.
1244 * config.sub: Translate ordinary names to three-part names.
1245 * configure: Use three-part names internally.
1246 * configure.in: Translate three-part names to filenames.
1248 * README, WHATS.NEW: Update for gdb-4.0.
1249 * Makefile.in: Roll VERSION to 3.99.
1251 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1253 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1254 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1255 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1256 to single structures rather than arrays; when passing
1257 their address, use &. This avoids trouble with bdead compilers.
1258 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1259 instead. This avoids portability headaches.
1260 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1262 * source.c (open_source_file): Avoid ANSI const bdeath by
1263 skipping declaration and then casting result value.
1264 * tm-hp300bsd.h: Clarify comment.
1265 * utils.c (strstr): Result is const char *; ANSI bdeath.
1266 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1267 since system include file defines it differently from "defs.h",
1268 though the two are equivalent for our purposes.
1269 * tconfig/hp300bsd: Add m68k-tdep.o.
1271 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1273 * tconfig/sun*4: Remove warnings about system assembler.
1275 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1277 * mcheck.c: Avoid warning about undeclared abort fn.
1278 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1279 it causes recursive calls to error() when used in cleanups.
1280 To do so requires that we make it a function, so we do.
1281 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1282 * utils.c (do_cleanups): Remove the current cleanup from the
1283 chain *before* calling it, in case error() is called from it.
1284 The result won't be pretty, but won't be an infinite loop either.
1286 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1288 * dbxread.c (read_struct_type): Grok anon structs for C++.
1289 (vb_name, vptr_name): Null terminate these strings.
1291 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1293 Minor bug fixes from BSD Net2 gdb:
1295 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1296 returns 0, there is no previous frame.
1297 * breakpoint.c (commands_command): If !from_tty, don't call
1298 input_from_terminal_p().
1299 * dbxread.c (record_misc_function): Speed up slightly.
1300 (compare_psymbols): Ditto.
1301 * infcmd.c (do_registers_info): Take a second argument to
1302 determine whether to print float registers. "info registers"
1303 does not do so anymore. "info all-registers" does, now.
1304 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1306 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1307 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1311 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1312 executing_breakpoint_commands if we are interrupted by error.
1313 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1314 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1315 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1316 catch_errors() so we can setup the frame regardless of whether
1317 the shared libs work.
1318 * ieee-float.c (double_to_ieee_extended): Get exponent from
1319 right place in little-endian systems. From John Carey.
1321 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1323 * main.c: Remove unused terminating_signals and catch_termination().
1324 (long_options): Terminate with a zero element.
1325 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1326 (gdb_readline): Make call-compatible with readline.
1327 (init_signals): Improve comments re vfork vs. signal.
1329 * utils.c (prompt_for_continue): Use new gdb_readline().
1330 If we prompt for continuation, we don't let CR repeat the previous
1331 command, once we get back to a prompt. It's too easy to keep
1332 hitting CR, expecting "--more--" prompts, and have some long
1333 command start repeating on you.
1335 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1337 * blockframe.c (frameless_look_for_prologue): Speed up by
1338 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1339 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1340 Define two variants, one faster.
1341 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1342 and return zero, rather than giving an error.
1343 (setup_arbitrary_frame): Initialize the PC in the new frame.
1344 (skip_prologue): Add a second arg saying whether we're just
1345 checking for a frameless function or not.
1347 * core.c (core_open, core_close, core_xfer_memory): Move
1348 section table pointers and bfd* into the target_ops.
1349 (core_open): Allow errors in shared lib reading, etc.
1350 (core_files_info): Describe shared library sections.
1352 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1353 exec_files_info, set_section_command): Move section table
1354 pointers and bfd* into the target_ops.
1355 (add_to_section_table): Add BFD to section table.
1357 * target.c (target_xfer_memory, target_info): Pass target to
1358 xfer_memory and target_info functions.
1361 * gdbcore.h: Move struct section_table.
1362 * target.h: New home of struct section_table.
1364 * solib.c (solib_add): New argument is the target_ops whose
1365 section list is to be added to, if any. Reallocate the
1366 sections in that target to add any that come from shared libs.
1367 (throughout) so_sections renamed to sections.
1368 (solib_xfer_memory): Deleted.
1369 * tm-sunos.h (SOLIB_ADD): Add target argument.
1370 (SOLIB_XFER_MEMORY): Delete.
1372 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1373 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1374 from target_ops. It's the same on all targets. Add two section
1375 pointers to target_ops.
1377 * stack.c (find_relative_frame): Dump ancient algorithm for
1378 "down", just use handy "next" pointers.
1379 (frame_command): Don't error if there is no stack; let user
1382 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1383 modifies static state in the parent process; new_tty itself
1384 runs in the child and modifies the child's file descriptors
1385 to match the saved static state.
1386 * infrun.c (child_create_inferior): Call new_tty_prefork,
1389 * infptrace.c (child_xfer_memory): Add ignored target arg.
1390 * remote-eb.c (eb_xfer_inferior_memory): ''
1391 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1392 * remote-vx.c (vx_xfer_memory): ''
1393 * remote.c (remote_xfer_memory): ''. Rename from
1394 remote_xfer_inferior_memory.
1396 * main.c (main): Only try to attach "corefile" argument if
1397 it starts with a digit.
1399 * symfile.c (symbol_reloading): New "set/show" variable.
1400 (symbol_file_add): Shorten message about symbol reading.
1401 (add_symbol_file_command): Merge with add_syms_addr_command,
1402 since this should work on all targets now.
1403 (stop_whining): Default to zero, to shut up complaints
1404 about bad symbol tables on many systems.
1405 (free_named_symtabs): Just exit unless symbol_reloading.
1407 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1408 and add comment explaining shared library screw.
1410 * source.c: #if defined => #ifdef.
1412 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1414 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1416 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1418 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1419 (doc/Makefile knows how to make one for local config)
1421 * Makefile.in: use doc/Makefile for doc targets
1423 * doc/Makefile: GDB documentation now has its own Makefile
1424 doc/refcard.tex: renamed from "gdbrc.tex"
1425 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1426 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1429 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1431 * values.c (baseclass_addr): When reading target memory, use the
1432 length of the basetype, not the upper type. We've only malloc'd
1433 enough space for the basetype, leading to errors in free().
1435 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1436 ends up as a function specially, since we know the actual type of
1437 the pointed-to address. This (somewhat) fixes display of
1438 expressions that include misc_function_vector names. Try `cond 1
1439 !strcmp("a","b")' then `i b'.
1441 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1442 The child can be proceeded from inside wait_for_inferior in
1443 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1444 getting skipped in that case.
1446 * expprint.c (print_subexp): Use filtered output, since the
1447 subroutines we call use it, otherwise the output is horribly
1448 mangled, since output of wrappable stuff comes out late.
1450 * Makefile.in: Bump VERSION to 3.98.1
1452 * infrun.c (child_create_process): Use execlp to find the
1453 shell to exec our target program. This requires some fiddling
1454 with `environ' since there is no execlpe().
1456 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1458 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1459 Minor rearrangement of refcard permits two new make targets--
1460 gdbrc.dvi DVI output for refcard, using CM fonts
1461 gdbrc.ps PostScript refcard, using PS fonts
1463 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1467 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1468 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1470 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1472 * doc/gdb.texinfo: last changes for release.
1473 Minor typo and formatting fixes; incorporated most fixes remaining from
1474 filed mail commenting on earlier drafts.
1476 Added warnings: pipes don't work in run command;
1477 conditions are converse of assertions;
1478 step over fn without debug info goes to next fn;
1479 vars may have "wrong" values near fn entrance, exit
1481 Added example from Kingston on printing repeated nonadjacent values
1483 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1484 shell mode for signals
1486 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1487 doesn't sound so much like its parent "Stopping and Continuing"; also
1488 moved entries on continue to top of section, so they don't get lost.
1490 Improved installation directions in appendix, added manual formatting
1493 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1495 * configure.in: Remove xm.h and tm.h even if we aren't linking
1496 new ones, so "./configure sun4; ./configure none" does the right
1497 thing. Assume that alldeps.mak and depend are already built in
1498 srcdir, and avoid running "make" (particularly "make depend",
1499 which involves "gcc") from inside configure. Build Makefile
1500 directly rather than building Makefile.conf first.
1501 * configure: Regenerate with above changes.
1502 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1503 to 3.98. Revise gdb.tar.Z procedure to produce a file
1504 called gdb-$(VERSION).tar.Z but which unpacks into a
1505 directory called "gdb". Move non-source files out of
1506 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1507 (depend): Don't try to do "gcc expread.y".
1508 (expread.o): Update dependencies by hand.
1510 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1513 Fixed a variety of small typos that prevented info from formatting
1514 cleanly; altered too-long heading for GPL Appendix, as discussed
1515 w/RMS; Changed date on cover to July 91.
1517 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1520 (1) Applied some fixes due to comments from Larry Breed (easier ones
1521 through chapsec 5.2)
1522 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1523 it's broken in latest texinfo
1524 (3) Introduced *some* use of [] for optional arguments, where
1525 explanation is not simpler by listing cmd w arg and cmd w/out arg
1526 separately. Still not using @deffn.
1527 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1528 couple of headings are too long. Need patches to texinfo or revision
1531 * Partial update to README (which still needs work for this
1532 release!): (1) use of configure corrected for new script,
1533 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1535 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1537 * symtab.c (lookup_symbol): Don't complain right off about
1538 no debug symbols; use the misc function vector first.
1539 (list_symbols): Use misc function vector to find symbols
1540 that don't have debug info, and print them.
1541 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1542 PC range doesn't match symtab PC range, as it does on the
1543 MIPS because our symtab reading isn't perfect.
1545 * dbxread.c (dbx_symfile_read): Make warning about
1546 "no debug symbols" slightly nicer.
1548 * source.c (select_source_symtab): If "main" symbol exists,
1549 but decode_line_spec can't find line info, don't just return
1550 a zero; try other source symtabs or give an error.
1552 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1553 their low addresses first, then rip through fixing high addrs.
1555 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1556 <runene@ifi.uio.no>.
1557 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1559 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1561 * Minor, mostly mechanical, cleanup of doc subdir for clean
1562 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1563 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1565 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
1567 Mostly MIPS and general symbol-reading fixups.
1569 * doc/gdbint.texinfo: Add documentation on symbol-reading
1572 * mipsread.c: Remove kludges around #include "ecoff.h".
1573 Remove redefinitions of a_magic, etc, no longer used.
1574 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
1575 Fix global overview comments to match symfile.c protocol.
1576 (mipscoff_new_init): Eliminate cur_hdr if we have one.
1577 (mipscoff_symfile_read): Eliminate unused code. Avoid
1578 sorting all the symtabs, when all we have read here is psymtabs.
1579 The symtabs are sorted as they are created anyway. Tell
1580 condense_misc_bunches whether we're mainline.
1581 (psymtab_to_symtab_1): Pass filename when recursing, to make
1582 stack trace more informative.
1583 (parse_partial_symbols): Assume cur_hdr as argument.
1584 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
1585 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
1586 the TYPE_NAME of char *, since that's done in symfile.c.
1587 (free_numargs, parse_symbol, add_symbol, add_block,
1588 shrink_linetable): Declare these fns void.
1589 (upgrade_type): Convert tree of if's to switch. Clean up
1590 bogus "off == 0" handling with a complaint. Avoid setting
1591 field bitpos and bitsize of array with lower and upper bounds.
1592 Check specified bitsize of elements against their actual type's
1593 bitsize, and complain if different. Complain about unknown
1595 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
1596 (psymtab_to_symtab_1): Print names of subsidiary files that
1597 are being read in. FIXME, we read far too many files. This code
1598 is not the problem, the problem is in parse_fdr where the psymtabs
1600 (cross_ref): Result should indicate that we used one aux entry
1601 normally, or two if we encountered a "next" entry. This used
1602 to leave the caller pointing at the wrong aux entry.
1603 (add_symbol): If overflowed cur_block, reallocate it larger,
1604 chase all pointers to it, and complain(), rather than clobber memory.
1605 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
1606 (new_field): Only allocate one field initially, not two.
1607 Pull ++ out of macro argument. Simplify.
1608 (_initialize_mipsread): Avoid initialization of importd
1609 global_psymbols and static_psymbols.
1611 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
1612 to properly set pst->symtab; avoid searching for it.
1613 (symfile_fns): Improve comments, add a FIXME.
1614 * dbxread.c: Update comments to reflect symfile protocol.
1615 (read_ofile_symtab, end_symtab): Return the symtab.
1616 (psymtab_to_symtab_1): Set pst->symtab.
1618 * coffread.c (coff_symfile_read): tell condense_misc_bunches
1619 whether we're mainline.
1621 * symfile.h (sym_fns): Remove unused sym_discard member.
1622 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
1624 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
1625 the environment variable is not.
1626 * infcmd.c (finish_command): Use filtered printfs.
1627 * cplus-dem.c: Add struct tags to a few unnamed structs.
1628 * valops.c (value_coerce_array): Improve comments.
1629 * valprint.c (type_print_varspec_suffix): Print array size only
1630 if greater than zero.
1631 * m88k-tdep.c: Shift some lines left by one space, that had
1632 apparently been trashed at some point.
1633 * TODO: More things to do, a few got done.
1635 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1637 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
1638 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
1640 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
1641 * expread.y, findvar.c, symmisc.c: Ditto.
1642 * printcmd.c (address_info): Update printed forms of LOC_
1643 symbols. Elim LOC_EXTERNAL.
1644 (print_frame_args): Keep track of param stack offsets before
1645 re-looking up to find the local register param is kept in.
1647 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
1648 Further integration of mipsread into gdb. Eliminate unused
1649 routines, duplicate declarations. Handle static symbols in
1650 psymtabs as well as external symbols. When reading symtabs,
1651 insert symbols into the correct block (global, static, or a local
1653 (read_mips_symtab, parse_partial_symbols): Don't pass useless
1655 (mipscoff_symfile_read): Don't call select_source_symtab.
1656 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
1657 rather than SYMBOL_VALUE.
1658 (parse_external): Comment clobbering of top_stack.
1659 (parse_partial_symbols): Update comments. Allocate and parse
1660 static symbols as well as external symbols. FIXME, enum values
1661 are not handled in this pass, but should be. Inline new_psymbol.
1662 Use SYMBOL_VALUE_ADDRESS.
1663 (psymtab_to_symtab_1): Read symbols into global static block
1664 by default (until enter some function's local block context).
1665 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
1666 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
1668 * source.c (select_source_symtab): Select a source symtab
1669 from either the symtabs or, failing that, the psymtabs.
1670 (list_command): Update error message.
1671 (forward_search_command, reverse_search_command): Use getc, not
1672 fgetc, for speed. FIXME, add comment about buffers that die if
1673 overrun by long line.
1675 * values.c (unpack_field_as_long, modify_field): Avoid shifting
1676 by an entire word, which is not portable, if we have a 32-bit
1677 field. (Code in dbxread.c already turns such bitfields, if
1678 aligned, into ordinary ints, but fixing this will help for other
1679 symbol formats and for future changes.)
1680 * core.c (core_open): Handle ANSI const brain death.
1681 * utils.c (vprintf): Fix varargs typo.
1683 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1685 * findvar.c (find_var_value): Handle &function better.
1686 * TODO: Document work needed on &fn and &array.
1687 * printcmd.c (print_address_symbolic): New arg is the prefix
1688 to print if a name is printed.
1689 (print_address_demangle): Honor "set print address" now.
1690 Use new arg above to improve spacing of output.
1691 * valprint.c (val_print): When printing function pointers,
1692 print symbolic form too.
1693 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
1695 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1697 * core.c (memory_error): Reword error msg to mislead less.
1699 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
1701 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
1702 parse_partial_symbols): Use newer BFD internals (external_filehdr
1703 and external_aouthdr), byte-swap the fields that we care about
1704 before using them, and make the file header data local to
1705 read_the_mips_symtab rather than global.
1707 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
1709 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
1710 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
1712 * main.c (command_line_input): Flush stdout and stderr
1713 before every call to readline. This reportedly fixes a bug
1714 that comes up in Sys V running emacs-gdb and/or xxgdb,
1715 when stdin/out are pipes or sockets.
1717 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1719 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
1720 Avoid declaring Makefile dependencies, because GNU Make stupidly
1721 tries to update it if we do.
1723 * coffread.c: Revise for minor changes to bfd internal coff
1726 * configure: If -template= is given a relative path, make it
1727 absolute before recurring in subdirectories.
1729 * configure, configure.in, Makefile.in: Install "configure" script
1730 as replacement for config.gdb.
1731 * config.gdb, Makefile.dist, Makefile.sdir: Remove
1732 * README: Update for configure, mostly. FIXME.
1734 * Add dec3100 as equivalent to littlemips. Indicate in all host &
1735 target config files that they are for the host. When the lines
1736 get copied into the Makefile, this makes it more obvious what's
1739 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1741 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
1742 tabs, which end up in the disassembler output inadvertently.
1744 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1746 Make it compile cleanly in an ANSI GCC2 environment.
1748 * blockframe.c: <stdio.h>
1749 * cplus-dem.c: free takes a void *, ifdef __STDC__
1750 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
1752 * defs.h (alloca): Avoid doing anything if alloca already def'd.
1753 * stddef.h, stdlib.h: Remove these files.
1754 * symtab.c: Avoid declaring qsort, close.
1755 * symfile.c: Avoid declaring close.
1756 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
1757 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
1759 Assorted other changes.
1760 * dbxread.c: include "libaout.h", not "liba.out.h".
1761 * printcmd.c (print_frame_args): Set recurse properly for
1762 indentation of struct and array parameters.
1763 * valops.c (value_cast): Allow cast to void.
1764 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
1765 single_step() in a target-independent fashion.
1766 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
1767 set up to be ready to continue. This makes us target independent.
1768 * infptrace.c (child_resume): Remove call to single_step; now
1769 can single step a SPARC target of any kind.
1771 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1773 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
1774 docn into separate sections---basically chapters, plus two loose
1775 pieces that can be configured to go in different places. This
1776 allows GNU m4 to preprocess the manual without coredumping.
1778 * Makefile.dist: tell TeX where to find texinfo.
1780 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1782 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
1783 the new target "rdl-apps.texinfo" which captures the Makefile
1784 variable that records where to find the Readline libraries.
1786 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
1788 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
1789 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
1790 * defs.h (const, volatile): Only define if not already defined.
1791 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
1793 * README: Update for release 3.95.
1794 * config.gdb: Don't create readline dir in subdir builds.
1795 * main.c: Include with "..." form for non-system include files,
1796 so "gcc -MM" for "make depend" works.
1797 Include readline files with "...h" rather than <readline/...h>.
1798 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
1800 * coffread.c: Undo minor damage done by Rich Pixley. Use
1801 different internal and external representations of COFF
1802 data structures. Use new BFD routines for swapping them in and
1804 * symfile.c (free_named_symtabs): Avoid freeing file names that
1805 are null or empty. Old i960 tools seem to produce files that
1806 claim to have empty names, causing each successive file read
1807 to blow away the previous one.
1808 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
1809 Move deferred_stores to top of file, but don't separate its
1810 #define's from its variable. Add commentary.
1811 * Makefile.dist: Fix Rich damage; undo "configure" changes in
1812 favor of keeping the (working) config.gdb. Move readline
1815 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
1817 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
1819 * infptrace.c (fetch_registers): no result, since now void.
1820 * tconfig/news: target depends on m68k-tdep too.
1822 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1824 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
1827 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
1828 applied various small fixes due to or inspired by RMS comments
1830 * doc/gdb.texinfo: finished using all RMS comments, save those for
1831 appendices on readline and cmd history (which are in other source
1834 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1836 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
1837 chapter 9; (2) documented 'break' command's menu mode for
1838 overloaded names, in response to hgs problem report C++ p-31
1840 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1842 * doc/gdb.texinfo: (1) better introductory example; (2) more
1843 consistent use of @code, @samp, @file, @kbd throughout; small
1844 cleanups to first three nodes; (3) new "Contributors" node;
1845 (4) Appendix, Renamed Commands; (5) divert specialized startup
1846 instructions to "Targets" chapter for generic manuals, while
1847 leaving them up front for manuals specific to specialized
1848 environments; (6) apply fixes from RMS comments through chapter 4.
1850 * pretex.m4: modify explanatory text slightly (and redefine
1851 "regexp") to keep GNU m4 from complaining. (It still crashes
1852 later, but one step at a time...)
1854 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
1856 * readline/readline.c (update_line): Avoid dereferencing a pointer
1857 before comparing it to its bounds. Saber caught this.
1858 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
1859 and only set PC if tgetstr returned non-null. Saber caught this.
1861 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1863 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
1864 stuff for config manual) here where it counts; updated
1865 to use new subdir structure (gdb/doc/).
1867 * Makefile: generated from above via
1871 * gdbint.texinfo: added instructions on generating gdb.info* files
1872 locally for release. These are ordinary info
1873 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
1874 Makefile)---but due to use of texinfo 2, can't count on makeinfo
1875 to generate these, so we distribute them already formatted.
1877 * gdb.texinfo: included full Info node and menu crud (as generated
1878 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
1880 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
1881 put in comments-for-future gdb.info target (one day makeinfo will
1884 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1886 * gdb.texinfo: Updated to include new or old undocumented
1887 commands, at least the following (perhaps some others I forgot to
1888 record): info f, info float, info path, info program, info s, info
1889 set, info source, info terminal, info types, info user, set/show
1891 Also covered all recent GDB command renames for v4.
1893 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1895 * mipsread.c: Rather than keeping count of how many symtabs
1896 and psymtabs we have, for sorting purposes, count them when
1897 we need to sort. This fixes bug in rereading of symbol tables.
1899 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1901 * infcmd.c: renamed "info path" to "show paths"
1902 * gdbrc.tex: documented above.
1904 Wed May 8 04:51:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1906 * remote.c: Fix comments.
1907 * utils.c (error): Force out any pending wrap output.
1909 Sat May 4 11:11:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1911 * Makefile.dist: Roll VERSION to 3.95.
1912 Fix up "saber_gdb" to work again.
1913 * saber.suppress: Update.
1915 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
1916 symtab.h, target.c, target.h: Lint.
1917 * core.c: setup and select frame after reading shared libs,
1918 else reading shared libs will clobber them. Lint.
1919 * utils.c (error): Force out any buffered wrap text.
1921 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1923 * remote.c: Remove decls of memory_insert_breakpoint
1924 and memory_remove_breakpoint, no longer used. (Suggestion of
1927 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
1928 to make it easier to interface to "configure"'d libraries.
1930 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
1932 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
1933 aliases for set/show print.
1935 Thu May 2 11:22:02 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
1937 * coffread.c (coff_sym_fns) [TDESC]: Make the type be m88kbcs.
1939 * m88k-tdep.c (IEEE_isNAN): New function.
1941 * infrun.c, m88k-tdep.c, m88k-xdep.c: Change
1942 initialize_{tdesc,dcontext} to init_{tdesc,dcontext}.
1944 * infrun.c [TDESC]: Add a bunch of crud.
1946 * xm-88k.h [__GNUC__]: Don't define memset.
1948 * m88k-xdep.c: #if 0 out push_breakpoint.
1950 * tm-88k.h: Define GET_SAVED_REGISTER.
1952 * tm-88k.h: Define DGUX.
1954 * m88k-opcode.h (UEXT, SEXT, MAKE): Put parentheses around arguments.
1956 * m88k-pinsn.c (sprint_address): Declare at top of file.
1958 * m88k-xdep.c: #if 0 out core_file_command.
1960 * values.c ({unpack_,value_as_}pointer): Just call
1961 {unpack_,value_as_}long (for now anyway).
1963 * m88k-tdep.c (get_saved_register): Make get_reg a dc_word_t (*)().
1964 (psr_register): Change return type to dc_word_t.
1966 * m88k-tdep.c (tdesc_read_function): Comment out call to ptrace.
1968 * m88k-tdep.c (get_saved_register): Add lvalp parameter.
1970 * gdbcore.h (write_memory): Don't prototype it.
1972 * tm-88k.h, m88k-tdep.c: Make stack_error, stack_jmp global.
1973 m88k-xdep.c: Don't mention stack_error.
1975 * {x,t}config/m88k ({X,T}DEPFILES): Add missing files.
1977 * mtrace.c: Don't typedef things like size_t, just #define them.
1979 * coffread.c [TDESC]: #if 0 out references to coffsyn.
1981 * symtab.h (struct symtab): Include EXTRA_SYMTAB_INFO.
1982 tm-88k.h: Define EXTRA_SYMTAB_INFO.
1984 * coffread.c [TDESC]: Include "tdesc.h" and make tdesc_handle
1985 dc_dcontext_t not int.
1987 * coffread.c [TDESC]: Use system include files not <intel-coff.h>.
1989 * coffread.c [TDESC]: Move setting of debug_info from

2458 * copying.awk (_initialize_copying): Rename "info copying" to
2459 "show copying" and "info warranty" to "show warranty".
2460 Rename {copying,warranty}_info to show_{copying,warranty}.
2462 * symfile.c: Rename add_syms_command to add_symbol_file_command.
2463 (_initialize_symfile, add_syms_addr_command):
2464 Rename add-syms to add-symbol-file.
2466 Thu Apr 18 18:08:30 1991 John Gilmore (gnu at cygint.cygnus.com)
2468 * symfile.h (free_named_symtabs): Rename from free_named_symtab.
2469 * symfile.c (clear_symtab_users_once, cashier_psymtab,
2470 free_named_symtabs): Move these routines from symmisc.c.
2471 * symmisc.c (same): same.
2472 (free_symtab): Make non-static.
2473 * symtab.h (free_symtab): Declare as exported void fn now.
2474 * dbxread.c (end_symtab, end_psymtab): Change comments.
2475 (initialize_dbxread): Call dbx_new_init() in case the first
2476 command is add-symbols.
2477 * target.c (dummy_target): Permit add_syms_addr_command.
2479 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2481 Permit symbols to be superseded when new symbol files have
2482 been read in, particularly for VxWorks.
2484 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
2485 to the main file, as well as to include files. Also, put global
2486 functions into the global psymtab, to make "i fun" work.
2487 (end_psymtab): Free named symtabs and psymtabs for a file, once a
2488 new psymtab for it has been read.
2489 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
2490 a file, once a new symtab has been read for it.
2491 * mipsread.c: FIXME. We need to do the same for MIPS, but it
2492 looks harder to determine the top-level block before it's been
2493 queued to the psymtab list.
2495 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
2496 If we have wiped out any old symbol tables, clean up at end of
2498 (symbol_file_command): Don't reference symfile_fns if it's zero.
2500 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
2501 defines for the blocks of a blockvector that contain global and
2502 file-static symbols and the first of the smaller scope contours.
2503 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
2504 decode_line_1, make_symbol_completion_list): Use the above.
2505 * coffread.c (end_symtab, patch_opaque_types): Ditto.
2506 * dbxread.c (end_symtab): Ditto.
2507 * expread.y (block): Ditto.
2508 * mipsread.c (throughout): Ditto.
2509 * symmisc.c (free_named_symtabs): Ditto.
2511 * symtab.c (list_symbols): Process the first symbol of the
2512 static psymbols list.
2513 (types_info): Restore this function from its untimely #if 0.
2514 It's not perfect, but it is better than nothing.
2515 (_initialize_symtab): Restore "info types".
2517 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2519 * m68k-stub.c: Remote stub for 680x0's, created from
2520 rem-m68k.shar (which is removed).
2521 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
2522 Remove RCS log stuff now that we use CVS and it blows our diffs.
2524 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2526 * symmisc.c (free_named_symtab): Make it work, in its current
2527 kludgy fashion. Change result to indicate if we blew away bkpts.
2528 * dbxread.c (end_symtab): Accumulate result from
2529 free_named_symtab and print warning if we blew user's state.
2530 * symfile.h: free_named_symtab now returns an int.
2532 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
2534 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
2535 is the first symbol read, even if not mainline.
2536 (dbx_psymtab_to_symtab): symfile might be zero, cope.
2537 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
2538 (set_section_command): New command ("section xxx yyy" -- should
2539 be renamed to "set section xxx yyy" FIXME) which sets the
2540 base address of a section of the exec file, overriding the
2541 virtual address that BFD reports.
2543 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2545 * exec.c: Add add_syms_addr_command to exec_ops, so you can
2546 load symbols at any address while examining an exec file.
2548 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2550 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
2551 for printing the float info is host-dependent, not
2552 target-dependent. FIXME.
2553 * i386-pinsn.c: Move #includes to top, remove useless ones.
2554 * i386-tdep.c: Don't bother including <.../reg.h> since we
2555 don't use it (and it doesn't exist on host systems).
2557 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
2558 Convert negative numbers properly.
2559 (ieee_test): Make numbers really random; fix format arg.
2561 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
2562 * core.c (core_detach): Unpush core_ops, which might not be on
2563 top. We used to just pop the top, which broke things. Don't
2564 need dont_repeat() any more.
2565 (core_file_command): Psst! Don't repeat it.
2566 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
2567 * expprint.c (print_subexp): Avoid switch fallthru on
2568 BINOP_ASSIGN_MODIFY, so we can print += and such.
2569 * frame.h: Fix typo.
2570 * inflow.c (kill_command): After killing inferior, print our
2571 current frame in the core file, if we have one.
2572 (generic_mourn_inferior): When inferior dies, either select
2573 the current frame (in the new target, e.g. core file), or
2574 set both the current and selected frames to NULL.
2576 Changes from Peter Schauer.
2578 * infptrace.c: Avoid <sys/ptrace.h> on USG.
2580 * Make all file names fit in 14 characters (sigh and damn!):
2581 mv hp300hpux-xdep.c hp300ux-xdep.c
2582 mv symmetry-xdep.c symm-xdep.c
2583 mv symmetry-tdep.c symm-tdep.c
2584 mv convex-opcode.h convx-opcode.h
2585 mv tm-vxworks960.h tm-vx960.h
2586 mv tm-vxworks68.h tm-vx68.h
2587 mv Makefile.srcdir Makefile.sdir
2588 mv gdb-int.texinfo gdbint.texinfo
2589 mv remote-sa.m68k.shar rem-m68k.shar
2590 mv remote-multi.shar rem-multi.shar
2591 * Makefile.dist, README, config.gdb, convex-pinsn.c,
2592 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
2593 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
2596 * command.c (user_info_1, user_info): New command for listing
2597 the user-defined commands.
2599 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2601 * dbxread.c (really_free_pendings): Clear file_symbols
2602 and global_symbols after freeing them; otherwise, running
2603 this function twice (if it appears twice on the cleanup
2604 chain), we try to free things twice.
2606 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
2607 based on text_addr (the address of text in core), not on addr (the
2608 offset between text in the .o file and in core). This change
2609 is from Peter Schauer.
2611 * main.c: Define ALL_CLEANUPS as a cast of zero.
2612 (return_to_top_level): Use it.
2613 (main): Do all cleanups after each command run as part
2614 of the gdb startup sequence. Also do all cleanups before
2615 entering the command loop, and every time we exit the command
2616 loop and reenter. Before, the cleanups from the startup sequence
2617 were being left undone until the first error!
2618 (command_loop): Rename do_nothing cleanup to command_loop_marker
2619 so we can see it easily when examining the cleanup chain.
2620 (init_signals): Add another do_nothing for signal handling.
2621 (quit_command): Only try to kill target if it has execution.
2622 Problems in the target stack got us into a state where
2623 inferior_pid was nonzero but none of the targets had execution.
2624 In this state you couldn't exit gdb.
2626 * dbxread.c: Two changes from Peter Schauer.
2627 (echo_command): Fflush output after an echo command.
2628 (show_history): Pass all args to cmd_show_list.
2630 * utils.c (init_malloc): Call mtrace to turn on tracing
2631 if the environment variable MALLOC_TRACE is set to a file name.
2632 * mtrace.c: Add source file which provides a log of every malloc,
2633 free, and realloc to a trace file.
2634 * mtrace.awk: Add source file which analyzes the trace file.
2635 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
2636 (VERSION): Roll to 3.94.3.
2638 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
2639 (check_duplicates): Don't bother with watchpoints.
2640 (set_raw_breakpoint): Comment about danger of this routine.
2641 (watch_command): Parse and eval all args before calling
2644 * solib.c (find_solib): Avoid error in referencing memory to
2645 see if any more shared libraries have been added. This is
2646 particularly useful if the target has terminated. Bug reported
2649 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
2650 in bringing up 3.94.2 on the Sun-3.
2652 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
2653 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
2654 expression (in scope) before reenabling watchpoint.
2655 * signame.c (init_sigs): Add missing declaration of i, fix
2656 sys_siglist declaration.
2657 * source.c (list_command): Fixed range computation to use
2659 * stack.c (backtrace_command): Do not allow command if target has
2660 no stack, print informative error message.
2661 * target.c (target_command): Do not write into command line
2662 because this fails if the target command is used in a user defined
2663 command. [This change was enhanced by gnu to support any-
2664 unique-prefix matching on target names.]
2665 * valops.c (value_struct_elt): Avoid infinite loop on an
2666 erroneous attempt to print the member of function (try p main.p).
2668 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2670 * expread.y (name_no_typename): Avoid reduce/reduce errors
2671 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
2672 Since the GDB parser really doesn't use name_no_typename in a
2673 name-only context, the parser can't tell the diff between
2674 names and numbers here. Avoid allowing a name_no_typename
2675 to be a NAME_OR_*INT to resolve the conflict.
2677 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2679 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
2681 * valprint.c (val_print_fields): bitfield printing didn't handle
2682 byte order. Indirect through a few more fns to cope.
2684 * values.c (modify_field): also cope with byte order.
2686 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2688 Cleanup for release 3.94.2:
2690 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
2691 include files. Roll version to 3.94.2.
2693 * coffread.c (init_stringtab): Read length into unsigned char
2694 array before swapping; don't assume 32-bit longs.
2696 * target.c (target_info): Don't bother with get_sym_file, just use
2697 the symfile global variable.
2698 * symtab.h, symfile.c (get_sym_file): Delete it.
2700 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
2701 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
2702 (read_type): Replace one more error() with complain().
2704 * mipsread.c (parse_partial_symbols): Replace printf with complain.
2706 * i960-tdep.c: Fix copyright attribution.
2708 * config.gdb: Quote all backquotes in doublequotes. You can
2709 quote me on that. BSD 4.4 shell found this one.
2711 * infptrace.c (throughout): The third argument to ptrace is an
2714 * infrun.c (wait_for_inferior): When program has terminated, we
2715 have to call target_terminal_ours before we pop that target off
2716 the stack (e.g. before a call to target_kill or
2717 target_mourn_inferior). This fixes problem where a program
2718 terminates, then GDB stops for (tty output) and you have to type
2719 "fg" to the shell to resume it. FIXME: This code for what to
2720 do after termination really should be in normal_stop instead.
2722 * gdbcore.h (read_memory_check): Change declaration; it changed
2725 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
2726 4.4 prereleases, this avoids a bug in their sgtty compatability
2728 * remote.c: Use terminal.h rather than hand-rolling the same.
2730 * signame.c, signame.h (psignal): Arg is unsigned, not int.
2731 * utils.c (strsave, strstr): Fix arg types.
2732 * valprint.c (val_print): lint
2734 MIPS symbol table support from Per Bothner:
2736 * symfile.c (symtab_fns): Remove initializer table that needs to
2737 be hacked for each new symbol file format supported.
2738 (add_symtab_fns): New function, chains symbol table
2739 handlers into the global list.
2740 (symfile_init): Search this list.
2741 * symfile.h: Add next pointer, declare add_symtab_fns.
2742 * coffread.c (_initialize_coffread): Call add_symtab_fns.
2743 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
2745 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
2746 symbol *). Thus, we no longer need the hack to trash
2747 pst->filename. Good, since that hack confused code in symfile.c!
2749 (reorder_symtabs, destroy_all_symtabs): Removed static
2750 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
2751 Instead, the latter now uses a temporary array (stack-allocated
2752 from an obstack, and then freed).
2754 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
2755 haven't been set in the outermost stBlock of a procedure. This was
2756 a problem with f77 binaries on Ultrix 4.?.
2758 (new_symtab, new_symbol, new_type): Continue changing code to use
2759 obstacks more and otherwise conform to dbxread internal style.
2760 Made the free_code of symtabs be free_linetable (as in dbxread)
2761 instead of free_contents. This implies memory leaks when reading
2762 a new symbol table, until the conversion is finished. Did change
2763 (struct symbol) and (struct type) to be allocated on the
2764 symbol_obstack. Blocks and blockvectors are among the things
2767 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
2768 tested much, but it solved one problem (reported by Meissner), and
2769 cleans up some other things. The problem happened when an
2770 included file contains actual code (functions) and not just
2771 definitions. The mips coff is a little inconvenient there, since
2772 it may cause a procedure to be mapped to the wrong psymtab.
2774 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
2775 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
2776 this will need work for the new core paradigm.
2778 Opcode patches from the net:
2780 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
2781 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
2782 missing altogether - they are added here. From Bruce Bauman.
2783 * mips-opcode.h: The low mask for C0 instructions was too small.
2784 From Garrett Lau. I modified the fix to check the entire 32-bit
2787 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
2790 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2792 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
2794 * dbxread.c (read_type): Pointer subtraction (value_sub in
2795 valarith.c) sometimes failed because the types of the
2796 pointers being subtracted were not identical.
2797 These differed because dbxread.c was allocating pointer types
2798 using dbx_alloc_type+smash_to_pointer_type instead of
2799 lookup_pointer_type. I failed to find a justification for the
2800 former, so I changed it to use the latter. Similarly, I
2801 replaced smash_to_function_type by lookup_function_type,
2802 and smash_to_reference_type by lookup_reference_type.
2804 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
2805 _initialize_mipsread): corresponding changes.
2807 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
2809 * source.c (mod_path): Do tilde_expand on each component of the path,
2810 rather than on the (list of) paths as a whole.
2811 (print_source_lines): Set first_line_listed in addition to
2812 current_source_symtab and current_source_line. If the source was
2813 not findable, after a "dir" command to fix the problem,
2814 a "list" would get the wrong lines.
2816 While I was there... (gnu):
2818 * dbxread.c (read_type): Change error to complaint.
2820 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2822 First attempt at detailed understanding of symbol table memory alloc.
2824 * dbxread.c (dbx_symfile_read): Free our string table if we
2825 aren't the mainline. Free the "info" struct since we're done with
2827 (init_psymbol_list): Free any previously allocated psymbol lists.
2828 (): FIXME: Should realloc-down the psymbol lists when done reading
2829 the main symbol file?
2831 * symmisc.c (free_symtab): Free fullname field too.
2833 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
2834 (REGISTER_ADDR): Make result type unsigned int.
2836 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
2837 define REGEX must also define REGEX1 (its dependency).
2839 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2841 * tconfig/i960: No longer works, points you at vxworks960 or
2844 * xgdb.c, XGDB-README: Remove file. Users can get the much
2846 * Makefile.dist: Remove all trace of xgdb.
2848 * breakpoint.c (breakpoint_1): Pass demangle arg to
2849 print_address_symbolic.
2850 (clear_breakpoints): Remove unused function.
2851 (breakpoint_re_set_one): Guts of breakpoint_re_set.
2852 (breakpoint_re_set): Use catch_errors to do them all anyway.
2854 * gdb-int.texinfo (Host versus Target): Add section on what is
2855 a "host" feature versus what is a "target" feature.
2857 * infcmd.c (path_command, path_info): Handle the PATH variable
2858 (object search path) as conveniently as the source search path.
2859 * environ.c (set_in_environ): Set some vars in GDB's environment,
2860 in addition to the child's. PATH, G960BASE, G960BIN for starters.
2861 * source.c (mod_path): New function, from guts of
2862 directory_command, modifies a path. Used by path_command.
2863 (directory_command): Call it.
2864 * defs.h (strsave): Declare.
2866 * utils.c (sevenbit_strings): Add new printing option.
2867 (printchar): Use it.
2868 (strsave): Provide this handy helper routine.
2869 (set_width_command): Rename set_screen_width_command.
2870 (_initialize_utils): "set screen-width" => "set width";
2871 "set screen-height" => "set height"; add sevenbit-strings.
2873 * infcmd.c (do_registers_info): Print floating point registers
2874 in raw hex as well as float format, regardless of whether it is
2875 a "virtual" convertible register.
2876 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
2877 regs as a double, just in case it's being used that way.
2878 * values.c (unpack_long): Comment on array/function coercion.
2879 (unpack_double): Argument is in target byte order now. For
2880 integer arguments, just call unpack_long and float the result.
2881 * m68k-tdep.c: include defs.h for "const" handling.
2882 * remote-nindy.c: Use ieee-float stuff.
2883 (nindy_fetch_registers): Unpack double regs to host double, then
2885 (nindy_store_registers): Pack extendeds to host double, flip
2886 around by misusing unpack_double, send as target double.
2888 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
2889 zero, as when stopped at the first instruction of a process.
2891 * blockframe.c: Fix filename in comment (param.h => tm.h).
2892 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
2893 * tm-68k.h: Fix typos.
2895 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
2897 Changes from a bringup on the DEC Vax under Ultrix 4.0.
2899 * coredep.c (fetch_core_registers): Pass end-address of register
2900 section to register_addr as expected. Don't call supply_register
2901 if we'd just pass it garbage.
2903 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
2905 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
2907 * target.c (push_target, target_info): Cast enums to int for < or
2910 * stack.c (print_frame_info): Identify source file & line
2911 even if we can't print it.
2913 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
2915 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
2917 Clean up IEEE floating point support.
2919 * ieee-float.h: New file.
2920 * ieee-float.c: Write real routines to convert between host
2921 doubles and various target IEEE extendeds.
2922 * m68k-xdep.c: Eliminate assembler code for extended floats.
2923 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
2924 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
2925 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
2926 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
2927 double_to_ieee_extended.
2928 * i960-tdep.c: Define ext_format_i960.
2929 * m68k-tdep.c: Define ext_format_68881.
2930 * sparc-tdep.c: Define ext_format_sparc, though unused.
2931 * Makefile.dist (HFILES): Add ieee-float.h.
2932 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
2935 Obsolete the "coffstrip" program in favor of using BFD's strip.
2937 * nindy-share/coffstrip.c: Remove file.
2938 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
2939 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
2940 * tconfig/nindy960: Remove reference to coffstrip.o.
2942 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
2944 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2946 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
2947 * dbxread.c: Remove static symfile_bfd.
2948 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
2950 * inftarg.c (child_detach): Pop the child_ops vector if the
2951 detach is successful.
2952 * remote-nindy.c (nindy_create_inferior): Don't push a new
2953 nindy_ops since nindy uses the same one for execution and memory
2955 * core.c (core_ops): Use child_attach and child_create_inferior
2956 rather than default attach and create_inferior functions.
2958 Handle floating point registers in core files.
2960 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
2961 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
2962 This version untested since BFD doesn't yet support sun3 core
2964 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
2965 conventions. Fix comments and style. This version has not
2966 been compiled yet, since we have no HP inhouse.
2967 * core.c (get_core_registers): Look for two sections, ".reg"
2968 and ".reg2", and pass both to fetch_core_registers sequentially.
2970 Revise directory path yet again.
2972 * source.c (forget_cached_source_info): Not static any more.
2973 (init_source_path): New default source path is "$cdir:$cwd".
2974 (dir_command): Handle variable arguments ($cdir, $cwd).
2975 (source_info): Print "Compilation directory" rather than
2976 "Originally compiled in" to remind people of $cdir.
2977 (openp): If the path contains $cwd, use current directory.
2978 (open_source_file): If compilation directory is known, replace
2979 first $cdir in path with the compilation directory.
2980 (print_source_lines): Even if we can't print the lines, set the
2981 current symtab and line for future commands like "info source" or
2982 "breakpoint". Also, error message now contains the file name,
2983 line number, and file access error message.
2984 (_initialize_source): Fix help text to describe changes.
2985 * main.c (cd_command): Forget cached source info when we chdir.
2986 * utils.c (strstr): Add simple implementation.
2988 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
2990 * coffread.c (read_one_sym, init_linetable, init_stringtab):
2991 Byte-swap COFF symbol tables if necessary when reading them in.
2992 Use complain() to replace error message in one spot. Needs
2993 corresponding change in bfd/coff-code.h to make some symbol
2994 swapping routines non-static.
2996 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
2998 Merge changes from Eirik Fuller, for UTek.
3000 * defs.h (errno): Add declaration.
3001 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
3002 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3003 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3004 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
3005 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
3006 declarations of errno.
3008 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3010 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3011 <rpc/rpc.h> and <rpc/types.h>.
3013 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3015 * i960-tdep.c (examine_prologue): Add new argument limit,
3016 which stops the scan at the end of the prologue, or at the PC.
3017 This fixes a problem where it walks down into the code for the
3018 user's statements if that code looks like function prologues.
3019 Mark Fox and I have been bouncing this code back and forth, making
3020 small changes to it. Callers changed to match.
3022 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3024 Cleanup for gdb-3.94 release final:
3026 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3027 the .c files from vx-share and nindy-share, from the various
3028 macros, since they are not found via ALLDEPFILES.
3029 (SFILES): Add tm-i960.h.
3030 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3031 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3033 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3034 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.

3038 * am29k-tdep.c: Add contribution line.
3039 (examine_prologue): Cache information about function prologues in
3040 the misc-function-vector to avoid lots of references over the
3041 serial line while examining instructions.
3043 * core.c (core_close): New function made from cleanup_core.
3045 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3046 remote-vx.c, remote.c, target.c, target.h,
3047 Update target_ops vector to add attach, close, and load entries.
3048 Use add_syms_addr_command, not add_file_addr_command, for
3049 add_file. Break out close routine from existing code.
3051 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3052 they are in an obstack.
3053 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3055 (define_symbol): Add symbol type parameter; change callers;
3056 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3057 it to influence the symbol class on the i960.
3058 (define_symbol): Swap LOC_CONST's into target byte order.
3060 * exec.c (exec_close): New function.
3061 (exec_file_command): Call it.
3063 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3064 Fix byte order of frame pointer.
3065 (read_var_value): Result of 0 if var's value can't be found,
3066 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3067 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3068 (locate_var_value): Use read_var_value and use its lazy address
3069 as the location of the var's value. Lint.
3071 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3074 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3075 obsolete Intel versions in favor of vxgdb versions.
3076 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3077 code dealing with byte order of values, which Intel did in host byte
3078 order rather than gdb-4's target byte order.
3079 (i960_frame_chain_valid): Move to nindy-tdep.c.
3080 (examine_prologue, skip_prologue, frame_find_saved_regs,
3081 frame_args_address, leafproc_return, saved_pc_after_call,
3082 pop_frame): Add vxgdb versions from Mark Fox.
3083 (examine_prologue, frame_struct_result_address): Add code
3084 to deal with the saved value of G13 (struct return address
3086 (frame_args_address): Modify Mark's version to prefer the
3087 saved value over the current value in the topmost frame.
3088 Cache result in the frame info to avoid performance hair in
3090 (print_fault): Add gdb960 code for printing faults.
3091 (_initialize_i960): Actually call check_host.
3093 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3094 add stub routines. FIXME, these currently just return zero!
3096 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3097 (attach_command): Call target_attach, not target_open, now.
3099 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3100 (child_attach): Rename from child_open.
3101 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3102 don't confuse it with a zero step_resume_break_address.
3104 * inftarg.c (child_detach): Eliminate inferior_pid test.
3105 (child_files_info): Clean up message a bit.
3106 (child_ops): Use child_attach, not child_open, to attach.
3108 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3109 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3110 findvar.c to here, since it depends on the contents of the
3111 shadow_contents of breakpoints, but keep if #if 0 since it is
3114 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3117 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3118 (ptype_command, display_command): Eliminate have_inferior_p and
3119 have_core_file_p in favor of target_has_stack or
3120 target_has_execution.
3121 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3122 code for actually finding the values of arguments, though we still
3123 keep track of the maximum stack offset for use in printing unnamed
3124 arguments. Handle missing FRAME_ARGS_ADDRESS.
3126 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3127 (struct nindy_regs): Define registers passed to/from nindy.
3128 (nindy_fetch_registers, nindy_store-registers): Translate between
3129 nindy and GDB formats for the registers.
3130 (dcache_init): Statically allocate the cache, since it was being
3131 allocated by a malloc that was never freed anyway.
3132 (nindy_create_inferior): Error, not core dump, if no exec file.
3133 (nindy_before_main_loop): Use target_load, not target_add_file.
3135 * remote-vx.c (net_load): Specify large timeout for load
3136 requests. Allow user to break out with INTERRUPT.
3137 (net_break): Remove useless code, clean up. Change callers.
3138 (parse-args, skip_white_space, find_white_space): Clean up arg
3139 parsing to cope with quoted strings.
3140 (net_wait, net_quit): Never call error, just return status.
3141 (vx_read_register, vx_write_register): Cleanup status checking.
3142 #ifdef the code based on which CPU we are using (960 or 68k),
3143 FIXME, this should be completely general but it isn't yet.
3144 (vx_xfer_memory, vx_resume): Cleanup status checking.
3145 (vx_run_files_info): Improve message.
3146 (vx_load_command): Renamed from vx_add_file_command. Allow load
3148 (net_ptrace): Remove unused routine.
3149 (vx_wait): Adopt code from vxgdb960 to cope with broken
3150 connections to target machine and prompt to disconnect. Remove
3151 debug printouts. Map some EVENT_'s to SIGnals.
3152 (add_symbol_stub, vx_open): Print names of object files we found,
3153 and "ok" if we read their symbols OK. Clarify output in general.
3154 (vx_attach, vx_detach, vx_kill): Add these commands.
3155 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3156 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3157 "info files" output, and create_inferior, since we already have
3160 * stack.c (frame_info): Replace Frame_unknown with 0.
3161 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3162 (return_command): Pop until the PC matches as well as the FP,
3163 so it works even if the FP is shared with another function,
3164 as in "frameless" or "leaf" procedures.
3166 * symfile.c (load_command): renamed from add_file_target_command.
3167 (add_syms_addr_command): renamed from add_file_addr_command.
3168 (add_syms_command): Stub to call target_add_syms.
3169 (_initialize_symfile): Change command names and descriptions,
3170 add-file => add-syms, and load from alias to its own command.
3172 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3173 maybe_kill_then_create_inferior): Default for attempts to start
3174 a process, if one is already running, is to ask about killing
3175 it and retry if yes.
3176 (upstack_create_inferior): #if-0 it, strata obsolete it.
3177 (push_target, unpush_target, pop_target): to_close() a target
3178 before unstacking it.
3179 (target_info): Renamed from target_files_info.
3180 (_initialize_targets): Rename "i files" as "i target", accessible
3183 * target.h: Improve comments about the target_ vectored routines.
3185 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3186 Convert commenting style to standard GNU style.
3187 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3188 (SKIP_PROLOGUE): No longer a no-op.
3189 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3190 (*_REGNUM): Sort register numbers.
3191 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3192 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3193 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3194 are now 10 byte extendeds, not 8 byte doubles.
3195 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3196 for nindy versus vxworks targets. FIXME, this should possibly go
3197 in the target vector.
3198 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3199 frame_saved_regs and arg pointer with each frame.
3200 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3201 (FRAME_ARGS_ADDRESS): Use cached result.
3202 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3203 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3204 (PRINT_RAMDON_SIGNAL): Call print_fault.
3205 (POP_FRAME): Now works.
3207 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3208 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3209 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3210 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3213 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3214 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3216 * valarith.c (value_subscripted_rvalue): Avoid handling
3217 floats and doubles specially; it gave alignment errors. Lint.
3219 * valops.c (value_of_variable, value_of_this): Error if unknown
3222 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3223 to avoid alignment problems.
3224 (value_print): Handle unknown value address.
3225 (cplus_val_print): Two args are ignored; remove them. Change caller.
3226 (val_print): Use unpack_long rather than pointer-deref.
3229 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3230 to avoid alignment problems.
3231 (value_being_returned): Error if return value unknown.
3232 (set_return_value): Add bogosity warning, FIXME. *
3234 * TODO: A woman's work is never done.
3236 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3237 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3238 Add ieee-float.o to OBS.
3239 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3240 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3241 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3243 Changes to generalize the VxWorks RPC protocol slightly, to handle
3244 i960 as well as 68000.
3246 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3247 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3248 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3249 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3250 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3251 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3252 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3253 so they will move in target byte order rather than network
3254 byte order (happens to be the same).
3256 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3258 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3260 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3263 Add contribution lines to various files, showing where they
3266 * breakpoint.c (break_insn, check_break_insn_size,
3267 read_memory_nobpt): Remove to mem-break.c.
3269 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3272 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3273 entry has bad register number. This change is not
3274 tested in this release, FIXME.
3276 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3279 * value.h: Force value's contents field to be aligned to hold
3280 at least a double or a long long (if supported). This avoids
3281 doing bcopy's in and out of the contents field.
3283 (step_1): Avoid coredump under obscure circumstances when we
3286 * symtab.h (misc_info): Add field to misc function vector for
3287 any kind of cached information the target code desires. AMD
3288 29000 uses this to avoid repeating examine_function_prologue's.
3290 * coffread.c: Lint. Remove static symfile, read_section_header.
3291 core.c (have_core_file_p): Lint: remove.
3292 expprint.c (print_subexp): Lint.
3293 infptrace.c, valops.c, valprint.c: lint.
3295 Roll in changes from vxgdb-5.0.1:
3297 * symtab.h: Comment byte order of each address class. Add
3298 LOC_LOCAL_ARG for frame-relative args (960).
3299 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3300 symtab.c, symmisc.c: ditto.
3302 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3304 * remote.c (remote_resume): Error if resume with a signal.
3306 * symfile.c (prim_record_misc_function): Clear misc_info.
3307 (fill_in_vptr_fieldno): Check stub type of arg.
3309 * valops.c (value_cast): Avoid looking up names of types whose
3310 name we don't know, to prevent coredump. Sun CC produces typedef
3311 rtx and the name of *rtx is zero...
3313 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3315 Roll in changes from final AMD 29000 port (Tiemann).
3317 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3318 for ../include/a.out.encap.h. This might not work now that BFD
3319 is separately compiled. Instead, BFD support for encap will have
3320 to translate machine type 29k into the right COFF_MAGIC.
3322 * infcmd.c: Remove references to inferior_pid that aren't used
3323 in actual ptrace calls; use target_has_execution, etc.
3324 (have_inferior_p): Remove function.
3325 (program_info): Print target info rather than "process number";
3326 avoid gratuitous messages unless from_tty.
3327 (run_stack_dummy, finish_command): Set proceed_to_finish.
3328 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3329 main.c: Lint. Lose have_inferior_p().
3330 inferior.h (have_inferior_p): Remove, lint.
3331 (proceed_to_finish): Add flag to ask that all regs be saved
3332 by normal_stop, for the few commands that need it, speeding up
3333 serial I/O. Add comments to stop_registers.
3335 * remote-eb.c: Remove newline from breakpoint message we grep
3336 for. Never time out when running the user program.
3340 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3342 Roll in changes from vxgdb-5.0.1:
3344 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3345 symbol in its raw form, we are processing an unlinked ".o" file.
3346 See if the target environment has assigned it an address, using
3347 target_lookup_symbol (VxWorks does), and enter it into the symtab
3350 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3351 68k versions for a simpler version that assumes zero FP at bottom.
3352 Fixes bug of truncated stack reports.
3354 * target.h (target_lookup_symbol): Define this routine's args
3355 and result, finally.
3357 * target.c (nosymbol): Default routine for target_lookup_symbol.
3358 (target_default): Default lookup_symbol and call_function too.
3359 (files_info): Only print has_all_memory warning if a non-dummy
3362 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3363 vx_convert_from_virtual): If target does not have floating point,
3364 zero register "values", and avoid doing cross-net conversions.
3365 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3366 (vx_open): Rearrange code that attaches to target and reads
3367 symbols for all loaded modules, to work if some of the modules
3368 are not accessible. Add symbol_stub() and add_symbol_stub()
3369 as callbacks from catch_errors(). Allow connect attempt to be
3370 interrupted painlessly with ^C (FIXME, there are still some bugs
3371 if the interrupt happens during symbol reading.). Print
3372 final message with puts_filtered, since symbol messages are
3377 * main.c (catch_errors): Only print errstring if non-null.
3378 (command_loop): Avoid an ioctl per command to test ISATTY.
3380 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3381 (vx_xfer_memory): Return correct result!
3382 (vx_files_info): Indicate whether target has float or not.
3383 (vx_lookup_symbol): Complain, not error, if target gone.
3384 (vx_open): Print "Connected" msg before disabling immediate-quit.
3385 [FIXME: lookup_symbol and vx_open changes need testing.]
3387 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3388 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3389 contributor lines and update copyrights to 1991.
3391 Changes from an attempted H-PUX host port:
3393 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3394 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3395 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3396 * remote-vx.c: include <sys/time.h> for HPUX.
3397 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3398 "core_file_command" routine to BFD regime. May not work yet.
3400 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3402 * xgdb.c: Replace X10 version with some VJ version.
3403 (FIXME: Its copyright assignment is not on record.)
3404 * xgdb.c: Update include files to X11R4 (Xaw crud).
3405 (xgdb_display_source, create_text_widget): fix call to
3406 get_filename_and_charpos. Rewack source window stuff for X11R4
3407 (gleaned from include files, and "nm's" of binary libraries, since
3408 I had no doc available).
3409 (append_selection, append_selection_word): Disable with FIXME
3410 since R4 changed interface here.
3411 (create_buttons): Add back the old set of buttons.
3412 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3414 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3415 Roll VERSION to 3.94 (not yet final though).
3417 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3419 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3420 obstack_int_grow, obstack_int_grow_fast): Eliminate
3421 cast on left of assignment, which gives MIPS cc fits and is
3424 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3425 F_ALIAS. Use printf, not fprintf, when not passing a file
3427 (compare_opcodes): Check that identical instructions have
3428 identical opcodes, complain otherwise.
3430 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3431 was reported by Roland McGrath.
3432 (unimp): Only match if exactly zero instruction. (Roland)
3433 (branches and traps): Generate all variations of these
3434 instructions with macros, based on a single call that defines
3435 each condition name and its binary representation.
3436 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3438 * valprint.c (val_print_fields): Take, and use, format parameter.
3439 This means that "p/x struct" again prints the elements in the
3440 desired format. Changed callers.
3442 * stack.c (frame_info): Use filtered output, and indicate wrap
3443 points. Remove kludgy formatting designed to avoid line wrap.
3445 * utils.c (wrap_here): If the line is already full (because
3446 we had printed a long indent or long wrapped string), do an
3447 immediate newline-and-indent.
3449 * m68k-pinsn.c (print_insn_arg): Bugfix from
3450 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3451 instruction is incorrectly disassembled as bkpt #8.
3453 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3454 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3455 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3456 and then will dump core (sometimes). I traced it back to an
3457 uninitialized symfile_name in psymtab_to_symtab.
3458 (const_vol_complaint): Add quotes to message.
3459 (define_symbol): Only believe line number if gcc_compiled.
3460 Avoid allocating symbol if we will not return it.
3462 Add target strata support so that newly established targets go
3463 into their right place in the target stack (e.g. a new exec file
3464 doesn't wipe out the ability to access the running process).
3466 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3467 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3468 and initialize it properly in all the targets.
3470 * target.h: Document strata. Change return type of push_target.
3472 * target.c (nomemory): new function for dummy memory access.
3473 (tcomplain): Rename complain, now also used in symfile.c.
3474 (push_target): Push targets within strata. New return value shows
3475 whether new target is on top of stack or not. Always keep dummy
3477 (target_files_info): Ignore dummy target.
3479 * core.c (core_open): Warn user, and skip accessing file, if the
3480 core target is not the topmost target in the stack.
3481 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3484 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3485 target_ops, it doesn't belong there since we have no regs there.
3486 Change name of target from machine => memory to clarify.
3488 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3490 * Freeze version 3.93 for release.
3492 * Makefile.dist: Handle vx-share and nindy-share subdirs
3493 properly when building gdb.tar.Z.
3495 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3496 printed in various places, so I could change just one copy.
3498 * dbxread.c, coffread.c: Change references to bfd->iostream
3499 to cast to FILE *, now that BFD avoids needing types defined
3500 in other header files.
3502 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3504 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3505 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3506 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3507 (actually gcc -Wall).
3509 * dbxread.c: Remove first_global_sym, last_global_sym, since
3510 they are never referenced.
3512 * defs.h (baud_rate): Declare.
3513 main.c: Define it, and add the -b option to set it.
3515 * gdb-int.texinfo: Add text on how to define a new host or target
3516 architecture, prompted by Per Bothner's questions about MIPS
3519 * gdb.texinfo: Document "complaints". Change doc of -q since
3520 gdb no longer prints the copyright and blurb if you specify a file
3521 name to be debugged (just like Emacs). Add doc for Nindy-specific
3522 command line flags for specifying target serial port and such.
3523 Update copyright to 1991.
3525 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3526 has taken over for us the job of ripping up executable files. The
3527 crud caused Per Bothner's port to not compile.
3529 * infrun.c (normal_stop): Avoid printing "Program exited
3530 normally" if we are in batch mode. This allows a GDB which
3531 executes a program on a target system, to behave like a Unix
3532 command (input from stdin, output to stdout, no extraneous
3535 * main.c (main): Allow additional machine-dependent command line
3536 options to be specified with the ADDITIONAL_OPTIONS,
3537 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3538 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3539 processing to occur just before the main loop with
3540 BEFORE_MAIN_LOOP_HOOK.
3541 (main): If a "core file" argument is specified, and it is not a
3542 core file, try it as a process ID to attach.
3543 (symbol_completion_function): Attempt to cope with
3544 "show screen-" TAB, not very successfully. This needs more work,
3546 (batch_file): New function, returns whether we are reading
3547 commands from an interactive tty on stdin, or from somewhere else.
3548 Called by normal_stop since it doesn't get from_tty passed down
3549 to it like many commands do.
3551 * remote-nindy.c: Handle command line options for nindy
3553 (nindy_before_main_loop): Prompt user for tty name if they
3554 don't specify it before getting to the interactive command loop.
3556 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3557 and -r command line options. Also add hook before main loop
3558 to make it easy to specify a tty.
3560 * TODO: More things to do, one done.
3562 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3564 * dbxread.c: Make complaint() calls pass pointer, not struct.
3565 Add complaints about badly formatted C++ type information
3566 (const/volatile indicator, and parse errors resulting in
3567 error_type). Fix C++ virtual member fn comment.
3568 (read_struct_type): Avoid bumping pointer if we got a parse
3569 error; this prevents our walking beyond the end of a string.
3570 Terminate loop on null char as well as semicolon.
3571 (process_one_symbol): Fix the LBRAC fix so that it uses the
3572 last previous SLINE, FUN, or SO record's PC address. C++ debug
3573 symbols did not have SLINE records in a useful order compared
3574 to the LBRAC records.
3575 (define_symbol): Handle "catch" records.
3577 * symtab.c (check_stub_type): Added new complain
3578 `stub_noname_complain' and added a consistency check to
3579 keep the debugger from crashing when finishing from an
3580 exception frame. A real fix will be needed later.
3582 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3584 * infcmd.c (attach_command): Make global.
3586 * Makefile.dist (REMOTE_OBS): Make these compile by default,
3587 but make them easy to comment out. Perhaps later they should
3588 be enabled by what CPU you configure for? FIXME.
3589 (VERSION): Roll to 3.93.
3590 (pinsn.o): Remove rule for obsolete file.
3591 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
3593 Run down a problem that manifested by printing the wrong function
3594 name in stack traces of read_ofile_symtab. Turned out that the
3595 problem was the SunOS 4.1.1 (and previous) C compiler outputs
3596 the LBRAC symbol with an address in the *data* segment, which
3597 blew our binary search through the blocks.
3599 * dbxread.c: Use the complain() facility consistently to bitch
3600 about problems in the symbol file we are reading.
3601 (finish_block): Add code to check the nesting of the blocks;
3602 complain and Procrust them to fit if wrong.
3603 (make_blockvector): Check the order of the blocks, complain
3604 [but don't cope] if wrong.
3605 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
3606 symbols to be sure their PC value is greater than the last SLINE
3607 (line number) symbol we've seen, complaining and adopting the
3608 SLINE PC value if wrong.
3610 * symfile.h (struct complaint, complaint_root, complain,
3611 clear_complaints): Add.
3612 * symfile.c (complain, complaint_root, clear_complaints): Add
3613 facility to deal with non-fatal complaints and to regularize their
3615 (symbol_file_add): Clear complaint counters to allow new complaints.
3616 (initialize_symfile): Add 'set complaints' and 'show complaints'.
3618 * dbxread.c (dbx_symfile_read): Remember the address and size
3619 of the string table for the main symbol file, so we won't read it
3621 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
3622 to avoid reading the string table yet again. Lint.
3623 (throughout): Improve filtered output, including word wrap.
3624 (read_range_type): Improve Bothner's fix to handle other types too.
3626 * utils.c: Improve line wrap implementation. Handle unlimited
3627 width by making chars_per_line unsigned.
3628 (puts_filtered): New, easy, function.
3630 * defs.h (puts_filtered): add.
3632 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
3633 call the identical sort_symtab_syms() in symfile.c instead.
3635 * expread.y: Suggest the `file' command rather than `symbol-file'.
3637 * command.h (enum var_types): Add zinteger for seroable
3639 * command.c (do_setshow_command): Handle var_zinteger. Restructure
3640 nested if's into a switch.
3642 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
3643 we did not stop because of a breakpoint (it must have been for
3644 some other reason, like a "stepi"), so don't print anything.
3646 * symtab.c: Include <sys/types.h> all the time. Now that BFD
3647 doesn't include <sys/types.h>, old SunOS's require it for
3650 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
3652 A test port of gdb-3.92.6 to the Sony NEWS.
3655 Don't normally link in remote- or vx stuff.
3656 Some of it doesn't compile, and it wastes space for 99% of the users.
3657 Remove reference to no-longer-used HAVE_VPRINTF.
3658 Fixed BFD_DEP typo to BFD_DIR.
3660 Fix cast in arg to bfd_h_getlong.
3661 Make char *prefix be const.
3662 Fix how certain range types are mapped into builtin unsigned int types.
3664 Remove 2 #includes. They cause errors (on Sony, at least),
3665 and aren't needed (they wern't in earlier versions).
3667 print_address_symbolic should never demangle labels
3668 (since it prints *assembler-level* labels).
3670 [This was superseded by the change to printcmd below.]
3673 Add some "volatile" return types to avoid warnings.
3674 If MISSING_VPRINTF add vprintf function and not just macro
3675 (since vprintf is used in printcmd.c).
3677 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
3678 (The latter isn't grokked by some PCC-based compilers.)
3680 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
3682 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
3683 * nindy-share/coffstrip.c
3684 Added some forward declarations (otherwise, gcc complains
3685 about implicit extern redefined as static).
3687 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3689 Changes inspired by Per Bothner:
3690 * printcmd.c (print_address_symbolic): Take additional parameter
3691 specifying whether to demangle.
3692 (print_address): Pass in asm_demangle to control demangling.
3693 (print_address_demangle): New fn, takes explicit arg to control
3695 * utils.c: Add new vars demangle and asm_demangle, and let them
3697 (fputs_demangled): If !demangle, just print the argument.
3698 (fprint_symbol): If !demangle, just print raw symbol.
3699 * valprint.c (val_print): Call print_address_demangle rather than
3700 print_address, to cause demangling to depend on the global
3701 rather than assembler-level demangling setting.
3702 * WHATS.NEW, gdb.texinfo: Document.
3704 * main.c (show_command): Show all settings if no arg.
3705 (initialize_main): Make "info set" the same as naked "show".
3706 * command.c (cmd_show_list): Handle prefix commands in the
3707 list, and print the name of the setting as well as its English
3708 description and value.
3710 Allow gdb functions to specify where a line should wrap if it
3711 exceeds the size of a terminal line. Use it to make the output
3713 * utils.c (set_screen_width_command): New fn, mallocs a buffer
3714 of the right size when screen width changes.
3715 (set_screensize_command, screensize_info): Remove #if 0'd fns.
3716 (wrap_here): New fn, indicates a point in the output where we
3717 should wrap the line rather than just letting it overflow at a
3719 (fputs_filtered): Implement wrapping.
3720 (n_spaces): New fn, returns a pointer to N spaces.
3721 (print_spaces_filtered): Use n_spaces.
3722 * defs.h (n_spaces): Declare.
3723 * stack.c (print_frame_info): Wrap with 4-space indent after
3724 fn name and before filename and line number.
3725 * printcmd.c (print_frame_args): Wrap with 4-space indent
3726 before each argument name is printed.
3727 * valprint.c (value_print): Wrap with no indentation before
3729 (val_print_fields): Wrap with indentation relative to nesting
3730 level before each field name.
3731 (val_print): Wrap with nesting indentation before array elements.
3732 * command.c (do_setshow_command): Avoid extra newlines,
3733 wrap with 4-space indent around values printed, end with period.
3734 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
3736 * breakpoint.c (breakpoint_1): Implement addressprint for
3737 "info breakpoints" display. Change file name and line number
3738 format to " at file:nnn" rather than " (file line nnn)".
3739 * gdb.texinfo: Document.
3742 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3744 Frozen for gdb-3.92.6 release.
3746 README, WHATS.NEW: Update for 3.92.6 release.
3748 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
3749 coffread.o from configs since it is now built by default.
3750 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
3751 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
3752 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
3753 from configs since it is now built by default.
3755 Makefile.dist: Update for release 3.92.6. Handle files that
3756 have been moved to ../include, ../getopt, or ../bfd. Add
3757 saber.suppress and tests directory. Add config.status to
3758 the release (it will say "none").
3760 coredep.c: Minor formatting fixes.
3762 These changes were made in early December but only checked in now:
3763 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
3764 nindy-share/nindy.c: lint
3765 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
3766 register values coming back from the target; we store values
3767 in target byte order everywhere.
3769 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
3771 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
3773 * valprint.c (cplus_val_print, val_print_fields): New functions,
3774 which print C++ objects. They conspire to avoid printing a
3775 virtual base class more than once, following all the twists and
3776 turns of C++ virtual base rules.
3777 (val_print): Call the above rather than do it by hand.
3779 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
3780 symbol file, not for added files like shared libs. This really
3781 needs to be generalized to a timestamp per file.
3783 * core.c (cleanup_core): Avoid coredump if no core file.
3785 * config.gdb: Accept -host or -target in place of +host or
3788 * coffread.c (find_linenos): Avoid desupported BFD interface
3789 to line numbers. We still read them manually rather than using
3790 BFD's "generic" features.
3792 * gdbrc.tex, threecol.tex: Add GDB reference card and its
3794 Makefile.dist: Add refcard to OTHERS list for creating tar files.
3796 * Makefile.dist: Eliminate use of $< in explicit targets.
3798 * readline/Makefile: Use $< rather than $*.c, which does not
3799 include the VPATH in GNU Make.
3801 * tconfig/i960-bout, tconfig/i960-coff: These are identical
3802 copies of tconfig/i960, added for global configuration
3803 compatability. All i960 versions can read both coff and b.out.
3805 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
3806 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
3809 * TODO: Think of more things to do.
3811 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
3813 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
3814 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
3815 64-bit float conversion.
3817 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
3818 equivalent to sun?os4 so global config works.
3820 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
3822 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
3824 * main.c: Only declare linesize once; declare pagesize not at
3825 all, since it is never used.
3826 (main): Clear newly allocated line before it is used.
3828 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
3830 Further stabilization for the Intel 960.
3832 * Makefile.dist: Parameterize the location of the "include"
3833 and "bfd" directories, as well as "getopt". Add symfile.c.
3834 Link in both dbxread and coffread. Fix up "make depend" to
3835 rewack the locations of include, bfd, and getopt in its output.
3837 * README: Document moving include files, improve some of
3840 * coffread.c: Move common code out to symfile.c. Change
3841 symbol_file_command style interface to use new *_symfile_init
3842 and *_symfile_read interface under BFD. Use BFD internal
3843 info to locate line table, symbols, etc.
3845 * core.c (core_fetch_registers): Rename to get_core_registers
3846 to avoid confusion with fetch_core_registers.
3847 (register_addr): Move to coredep.c, which is already machine
3848 dependent. This leaves core.c pretty clean of dependencies.
3850 * coredep.c (register_addr): Accept this routine from core.c.
3852 * dbxread.c: Move common code (with coffread.c, etc) into new
3853 symfile.c. Each psymtab now contains a pointer to the
3854 format-dependent function that knows how to read it in. Make
3856 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
3857 (process_one_symbol): Add code to complain about a "compiler bug
3858 we muzzle here", if we actually see it.
3860 * eval.c (evaluate_subexp): Insert missing "break" statements
3861 in code that determines whether a variable is an lvalue in
3862 memory, register, or whatever. I detected this via a compiler
3863 bug in which it *almost* mashed out the whole switch statement.
3865 * gdb-int.texinfo: Add minor sections on configuring gdb for
3866 release, and about the README file.
3868 * infcmd.c (registers_info): Fix formatting somewhat. Still
3869 not as pretty as before, but it handles byte swapping.
3871 * remote-nindy.c: If data cache routines are interrupted while
3872 waiting for the remote end, be sure that any uninitialized cache
3873 blocks are on the free list, not on the valid list!
3875 * symfile.h: Flesh out this header file with all the various
3876 routines and variables that have been merged in from dbxread.c
3877 coffread.c, and symtab.c to symfile.c.
3879 * symfile.c: New file, containing code common to dbxread.c,
3880 coffread.c, and some code from symtab.c. All generic code for
3881 reading symbol files should be in here now.
3882 (unrecord_misc_function): Remove unused function.
3884 * symtab.h: Remove file-reading things to symfile.h.
3886 * symtab.c: Remove file-reading things to symfile.c.
3888 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
3889 to decode i960 fault types.
3891 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
3892 target.c: Change type of the "resume" function from int to void,
3893 since its result was never used.
3895 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
3897 * main.c: Replace "stupid" with "caution"; you now "set caution
3900 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
3902 * infcmd.c (do_registers_info): Call val_print to deal with the
3903 byte order of the registers being printed. FIXME, this makes
3904 the formatting of the output uglier.
3906 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
3907 defined, call it for signals the debugger doesn't itself use.
3908 The i960 uses this for more detailed fault information.
3910 * remote.c (remote_open): If arg is null, print help rather than
3913 * sparc-xdep.c (register_valid): Avoid declaring size, since
3914 various modules will think of various sizes depending on the
3915 architecture of their tm-file. FIXME, we need protection against
3916 actually entering one of those modules, which would clobber
3917 storage if not for the target architecture compiled into gdb.
3919 * stack.c (up_command, down_command): Always print the frame
3921 (up_silently_command, down_silently_command): New commands
3924 * i960-pinsn.c (reg), i960-tdep.c: Lint.
3926 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
3927 more parameters than it used to.
3929 * findvar.c (registers): Increase slop to 256 bytes, which should
3930 protect us against even most RISC machines with large register
3932 (locate_var_value): Move declaration inside related ifdef.
3934 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
3935 throughout, to avoid throwing away buffered input from the board.
3936 (nindy_wait): Supply_register takes addr_of_value, not value.
3937 (i960_print_fault): Renamed from i80960_fault.
3938 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
3939 (nindy_store_registers): Avoid regs_changed stuff, just stuff
3941 (nindy_create_inferior): Don't bother to write PC_REGNUM since
3942 we can set the PC in the call to proceed(). Unpush nindy_ops
3943 before pushing it on top, to avoid message to user. Eliminate
3944 commentary from Unix machines that just misleads here.
3945 (reset_command): Fix error message to suggest target command.
3947 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
3949 Release 3.92.5 as frozen.
3951 Stabilize the merged release...with help from lint, Saber C,
3954 Everywhere: Add include files needed to declare return types
3955 of functions called.
3957 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
3959 * breakpoint.h: Add undeclared breakpoint functions, and some
3960 functions for display handling since I couldn't think of a better
3963 * breakpoint.c (insert_breakpoints): Make code for disabling
3964 shared library bkpts more likely to work. It's used when we
3965 rerun a program and stop before the shared library has been
3967 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
3968 cast from pointer, so it squeezes through catch_errors.
3969 (bpstat_stop_status): Fix logic broken some time ago. We now
3970 always create a bpstat if the stop address matches a breakpoint,
3971 even if we don't stop there -- just like the old code used to do
3972 before I got my fingers into it (sigh).
3973 (breakpoint_1): Print "ignore count" after "stop only if"
3974 condition, since that's how it actually works.
3975 (mention): Handle watchpoints as well as breakpoints.
3976 (watch_command): use set_raw_breakpoint and mention to do most
3977 of the work (and initialize all the fields!). Only pass one
3978 arg to parse_c_expression, since that's all it takes.
3980 * command.c (not_just_help_class_command): Rename arg to args
3981 since we ignore "unused argument" warnings on vars named "args".
3982 inflow.c (child_terminal_info): ditto.
3983 infptrace.c (kill_inferior): ditto
3984 main.c (catch_errors, version_info, quit_command, pwd_command,
3985 source_command, dump_me_command, editing_info,
3986 set_history_size_command, set_history, show_history,
3988 stack.c (locals_info): ditto
3989 target.c (target_files_info): ditto
3990 valprint.c (set_input_radix, set_output_radix): ditto
3992 * core.c: Remove old variables for handling core and exec file
3993 sections (data_start, data_end, stack_start, stack_end,
3994 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
3995 text_end, exec_data_start, exec_data_end, text_offset,
3996 exec_data_offset, data_offset, stack_offset). They're
3997 superseded the more general build_section_table and
3999 (get_exec_file): Mention the `file' command.
4000 (read_memory_check): Rename to memory_error, and only call it
4001 in the case of an actual error.
4002 (read_memory, write_memory): call memory_error.
4003 (core_fetch_registers): Register section name is ".reg".
4005 coredep.c: Remove a bunch of crud now that all this file does
4006 is pull the registers out of a core file.
4007 (fetch_core_registers): Rewrite to actually work, I hope.
4009 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4010 Replace index() with strchr(). Remove all the pre-BFD macro
4011 definitions for accessing the symbol file.
4012 (struct dbx_symfile_info): Encapsulate the information that
4013 dbx_symfile_init needs to pass to dbx_symfile_read in this
4016 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4017 dbx_symfile_discard): Rearrange symbol file reading to divide
4018 the format-specific part from the format-independent part,
4019 leaving the format-independent part such as file name expansion
4020 and opening in symtab.c. This replaces
4021 partial_symbol_file_open and partial_symbol_file_read.
4022 Symbol_file_read, add_file, add_file_target_command,
4023 add_file_addr_command move to symtab.c. Pass an explicit
4024 "mainline" flag for when reading the main symbol table, rather
4025 than relying on the offset address to be zero or nonzero.
4027 (dbx_symfile_read): Don't allow void *'s to be printed as
4029 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4030 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4031 macro" debug version really work.
4032 (read_dbx_symtab): Remove unref'd parameter inclink.
4033 Avoid swapping N_SLINE symbols, for speed.
4034 Merge N_TEXT!N_EXT case with the other external symbol
4035 definitions' case. Add comments.
4036 (start_psymtab): Allocate the symfile name in the psymtab on
4037 the psymbol_obstack, rather than using the caller's storage.
4038 (end_psymtab): Only allocate a dependencies list if there are
4040 (psymtab_to_symtab_2): Use BFD when reopening file to read
4041 its symbols for real.
4042 (read_struct_type): Add FIXME comments where it needs work
4044 (read_huge_number): Add FIXME about overflows.
4045 (read_range_type): Add FIXME about comparing a long to 1<<32.
4047 * coffread.c: Minor changes to move things closer to the new
4048 regime with symtab.c and dbxread.c Major work is still needed
4051 * exec.c (exec_file_command): Remove old variables (see core.c
4053 (xfer_memory): If memory transfer is right at the end of a
4054 section, don't lose.
4056 * findvar.c (get_saved_register): If value is in a real
4057 register, LVAL is lval_register, not lval_memory.
4059 frame.h: Declare print_sel_frame and record_selected_frame.
4061 gdb-int.texinfo: New file, for GDB internals documentation.
4062 Very simple, unformatted doc of cleanups is there for now.
4064 gdbcore.h: Remove obsolete variables that described a.out
4065 section addresses and offsets. (See core.c above.)
4066 Declare fetch_core_registers and registers_fetched.
4068 getopt.c: Declare char *alloca(); even on SPARC.
4070 infcmd.c (run_command): Call target_kill rather than
4072 (step_command, next_command, stepi_command, nexti_command):
4073 Declare from_tty parameter even though we don't use it.
4074 (run_stack_dummy): argument BUFFER is a char array, not
4075 a pointer to REGISTER_TYPE.
4076 (finish_command): using_struct_return needed a value *,
4077 not a struct symbol *.
4079 * infptrace.c (child_xfer_memory): To avoid dependency on
4080 where sections are in memory, try PT_WRITE_D and if that fails,
4081 try PT_WRITE_I. Most Unixes don't care which you use.
4083 * infrun.c (step_resume_break_shadow): Change to array to
4084 match other breakpoint shadow storage.
4085 (clear_proceed_status): Pass address of bpstat to
4086 bpstat_clear, not the bpstat itself.
4087 (child_create_inferior): FIXME comment about if the child
4089 (start_inferior): Remove old function.
4090 (child_open): Use target_kill rather than kill_inferior.
4091 (wait_for_inferior): Ditto.
4092 (insert_step_breakpoint, remote_step_breakpoint): Use
4093 new step_resume_break_shadow.
4095 * inftarg.c (child_wait): If all child processes die,
4096 pretend that the one being waited for exited with signal 42.
4098 * main.c (command_line_input): When scanning for comments,
4099 don't coredump on unclosed quotes.
4100 (quit_command): Use target_kill rther than kill_inferior.
4101 (_initialize_main): Rename class_user from "user" to
4104 * printcmd.c (print_command_1): Initialize "fmt" if no format
4105 is specified by the user.
4106 (print_frame_args): Only add to args_printed if we are
4107 actually fetching args from the stack (avoiding undefined
4109 (_initialize_printcmd): Remove bogus \{ from string.
4111 * remote-eb.c (eb_open): Avoid coredump on no argument.
4113 * remote-nindy.c: Bring out of Intel environment into new
4114 target environment. Remove all conditional compilation on
4115 I80960. Massive hacking throughout.
4116 (nindy_xfer_inferior_memory): New routine stolen from
4118 (nindy_create_inferior): New routine pieced together, probably
4119 not quite working yet.
4120 (nindy_ops): New target_ops struct for nindy.
4122 * remote-vx.c: Use write_memory rather than target_write_memory
4123 to get error checking.
4124 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4126 (vx_create_inferior): Use target_terminal_ours...
4128 * signame.c (_initialize_signame): Always initialize, since
4129 we need the table for things other than psignal.
4131 * solib.c (solib_add): Use symbol_file_add, not add_file.
4132 (solib_address): Return boolean result rather than struct
4133 pointer which nobody else knows the type of.
4135 * sparc-tdep.c, valops.c: Use write_memory rather than
4136 target_write_memory, to get error checking.
4138 * stack.c (locals_info, catch_info, args_info,
4139 get_selected_block, frame_command, up_command): Use
4140 target_has_stack, rather than have_inferior_p or
4143 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4145 * symfile.h: New file, defining the interface between the
4146 generic and object-file-specific symbol reading code.
4148 * symtab.c: Move generic symbol-reading interface to symtab.c,
4149 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4150 table to map BFD targets to symbol-reading modules in GDB.
4151 Change index to strchr.
4152 (lookup_struct_elt_type): Use error() rather than hand-made
4153 simulations thereof.
4154 (lookup_partial_symbol): Speedup slightly when length == 0.
4155 (symbol_file_add): New function.
4156 (symbol_file_command): Call it.
4157 (symfile_open, symfile_init): New function.
4158 (add_file_target_command, add_file_addr_command): moved from
4161 * target.c (target_command): use target_kill.
4163 * target.h (target_files_info): Don't declare, never called
4166 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4167 files to determine stack end address.
4169 * valarith.c (value_x_binop, value_x_unop): Change error message
4170 to be more useful. Pass proper argument to value_struct_elt.
4172 * valops.c (value_assign): FIXME comment that long long
4173 bitfields will break here.
4175 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4176 Update `make saber_gdb' to work better.
4178 * TODO: A woman's work is never done.
4180 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4181 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4182 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4183 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4184 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4185 valops.c, valprint.c, exec.c: Lint.
4188 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4190 Continuing Intel 960 port merge of GDB.
4192 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4193 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4194 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4195 Wack over "make depend" so it handles files in subdirectories
4196 vx-share, nindy-share, bfd, and in the current directory.
4198 * blockframe.c (get_prev_frame_info): Remove fatal error
4199 if stack not defined.
4201 * core.c (core_open, core_detach): New functions that handle
4202 the old "core-file" command as "target core" and "detach" instead.
4203 (core_file_command): Call them.
4204 (core_xfer_memory): Use common routine xfer_memory.
4206 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4207 dbxread now uses bfd for everything but symbol reading itself.
4208 BFD internals are used to drag out the relevant file offsets.
4209 (partial_symbol_file_open): Change args all around for BFD.
4211 * symtab.c: Rename "value" to "val" everywhere, so we can
4213 (symbol_file_command): New command, moved from dbxread.c
4214 and coffread.c. It uses BFD to read the file, then vectors
4215 based on its type, to dbx or coff symbol readers.
4216 * symtab.h: Extern a few vars for symbol_file_command.
4218 * target.h: Breakpoint takes a char * save area, not a char **.
4220 * valprint.c (val_print): When unpacking bitfields, offset
4221 the address in gdb of the value, if it is declared with a shorter
4222 type. Remove the last "runtime kludge test" of host byte order.
4224 * utils.c: Remove old my_bfd_read routine.
4226 * stack.c (frame_info): Use target_has_stack. Print program counter
4227 register's actual name rather than "pc", since it's called the
4228 "ip" (instruction pointer) on the i960 (sigh).
4230 * target.c (target_command): Add command for selecting a target
4231 type and calling its open routine. This is used for initiating
4232 communication with a particular target, in a generic way.
4234 * tm-i960.h: Update for modern gdb. Remove semicolons from
4235 various macros. Handle reading struct return convention, and
4236 error-out attempts to return structs with the "return" command.
4237 Be sure gdb doesn't think we know how to call functions in the
4240 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4241 to i960_xxx in lower case.
4242 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4243 not being defined yet.
4245 * remote.c (remote_open): Call start_remote to initialize
4246 wait_for_inferior during open.
4247 (remote_xfer_inferior_memory): Return length written rather
4250 * remote-vx.c (target_command -> vx_open): Use new generic
4252 * remote-eb.c, inftarg.c, exec.c: ditto.
4254 * infrun.c: Fix comments.
4255 (attach_program -> child_open): Use new generic target command.
4256 (wait_for_inferior): Clear saved register values before target_wait,
4257 so target_wait can set some of them if convenient.
4259 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4260 Return success indicator, not void.
4261 (child_xfer_memory): Avoid fetching initial word if we'll
4262 overwrite it anyway.
4264 * infcmd.c (attach_command): Use new generic target open routine.
4265 (_initialize_infcmd): Update doc on attach and detach commands.
4266 (do_registers_info): Merge in a byte-order problem as a FIXME
4269 * findvar.c (find_saved_register): Avoid problem in current frame.
4270 (read_relative_register): Ditto.
4271 (write_register): Convert byte order on the way out.
4273 * exec.c (file_command): Add.
4274 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4275 (xfer_memory): Common function between core_xfer_memory and
4277 (exec_xfer_memory): Use it.
4279 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4281 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4282 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4283 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4285 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4287 Merge Intel 960 port of gdb, continuing...
4289 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4290 symbol_file_command): Pass from_tty arg to hush 'em up.
4292 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4293 Add magic numbers for 960 COFF format.
4295 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4297 Merge Intel 960 port of gdb, from Intel "1.2" release.
4299 CHANGE_LOG entries from their port, which was based on
4302 Thu Sep 6 11:02:22 PDT 1990
4303 Remove temp file if download is interrupted.
4305 Wed Aug 1 09:08:33 PDT 1990
4306 Now uses binary protocol to talk to NINDY.
4307 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
4308 Times out after 5 seconds when trying to talk to NINDY.
4310 Tue May 29 12:54:49 PDT 1990
4311 Added variable baud rate (-b switch).
4312 Source code reorganization.
4314 Thu Apr 26 11:09:55 PDT 1990
4315 More cleanup of batch mode; specifically, execute "-s", "-e", and
4316 "-se" switches as soon as they are encountered on the invocation line.
4318 Fri Apr 20 13:47:15 PDT 1990
4321 Thu Apr 19 09:54:28 PDT 1990
4322 Add 'reset' command.
4324 Wed Apr 18 09:48:07 PDT 1990
4325 After opening remote tty, wait for 1 second to go by without input
4326 from it before trying to talk to NINDY (fixes problems with the
4327 Heurikon HK80/V960E).
4329 Mon Apr 4 16:33:05 PDT 1990
4330 Some output was not being suppressed in 'batch' mode.
4332 Thu Mar 22 15:31:11 PST 1990
4333 Ask user if old symbol table should be deleted when new file is
4336 Allow user to run a program downloaded before gdb960 was brought up.
4338 Correct "exec-file" help message for i80960 context.
4340 Correct bug in calculating user space address: could occasionally
4341 corrupt user program.
4343 Make sure to zero low-order bits in rip's because of bug in 960CA
4344 A-step part: could cause operation faults when "next"ing across
4347 Correct bug that made it impossible to get source line numbers for
4348 code loaded at addresses higher than 0x7fffffff.
4350 Wed Jan 10 12:43:22 PST 1990
4351 Open remote tty for exclusive use.
4353 Fri Jan 5 12:14:42 PST 1990
4354 Correct disassembly (CA manual was right after all):
4355 opcode for sysctl is 0x659
4357 Mon Oct 23 12:03:04 PDT 1989
4358 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4360 Mon Oct 16 14:15:09 PDT 1989
4361 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4363 Mon Oct 2 15:56:31 PDT 1989
4365 Added 960CA disassembly support.
4367 To simplify maintenance:
4368 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4370 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4371 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4372 - made disassembly interface identical to that in gdmp960.
4376 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4378 * target.h: Allow targets to stack. Add target_has_memory,
4379 _registers, etc. Restructure memory access and "info files"
4380 to walk the target stack.
4381 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4382 target.c: Change tables to match target.h.
4383 * inflow.c (child_mourn_inferior): pop child_ops.
4384 (generic_mourn_inferior): Use new has_stack flag.
4385 * infptrace.c (child_xfer_memory): New memory regime.
4386 * inftarg.c (child_files_info): New "info files" regime.
4387 * remote-eb.c: New memory regime, new info files.
4388 * remote-vx.c: New memory regime, new info files. Now use
4389 separate targets for VxWorks attachment to machine, and
4390 actually running a process under VxWorks, since one has
4391 stack & execution & regs and the other doesn't.
4392 * remote.c: New memory regime, new info files.
4393 * sparc-xdep.c (fetch_core-registers): New memory regime.
4394 * target.c: New routines and support for stacked targets,
4395 new memory regime, new info files regime.
4398 Generalize section handling for an arbitrary number of sections,
4399 including use of the new BFD (binary file) library.
4400 * gdbcore.h: Add struct section_table.
4401 * exec.c (build_section_table): Iterate all sections and
4402 record what gdb needs to know about them.
4403 (exec_command): Use it.
4404 (exec_xfer_memory): Use the table.
4405 (exec_files_info): Print the table.
4406 * core.c (core_file_command, core_xfer_memory, core_files_info):
4408 * source.c (find_source_lines): Use bfd_get_mtime.
4409 * dbxread.c: Quick changes to make it compile with new BFD.
4410 * utils.c (error): Avoid using bfd_error in generic routines.
4412 * core.c (core_fetch_registers): Get from the ".regs" section of
4414 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4416 * inferior.h (attach_flag): Export.
4417 * infcmd.c (run_command): use new target_create_inferior.
4418 * infrun.c (child_create_inferior): Don't return result.
4419 * Makefile.dist (VERSION): 3.91.4.
4421 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
4423 * breakpoint.c (bpstat_num): Handle breakpoints which have
4424 since been deleted, such as temporary breakpoints.
4425 infcmd.c (program_info): ditto.
4427 * core.c (core_file_command): Display the frame where the core
4432 * remote-vx.c (target_command): Merge in target command from
4433 targ-vx.c. A few other cleanups.
4435 * TODO, Projects: Lots more stuff to do...
4437 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4439 Massive changes to wall off the remote-debugging interface
4440 behind a function vector. The port to handle VxWorks targets
4441 is also part of this.
4443 All files: Replace references to renamed functions,
4444 remove references to remote_debugging, remove references to
4445 have_include_file, have_core_file in favor of target_has_stack,
4446 target_has_memory, etc.
4448 * Modularize the breakpoint interface.
4449 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4450 a breakpoint instruction.
4451 breakpoint.c: struct breakpoint's shadow_contents now sized as
4453 (insert_breakpoints): Vector to target to install breakpoints.
4454 (remove_breakpoints): Vector to target here too.
4455 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4456 sparc-tdep.c (single_step): Use new breakpoint interface for
4457 the single-step breakpoints.
4458 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4459 New file, contains routines to insert and remove breakpoints by
4460 reading out the old contents and later replacing them. This is
4461 how ptrace breakpoints work, and many remote systems as well.
4463 * tm-vxworks68.h: New config file, overrides a few things for
4464 Wind River's preferences.
4466 * target.h: New file, for transfer vector used to talk to the
4467 inferior (child, attached, core, exec, remote, etc). All accesses
4468 to the thing being debugged should come through these vectors.
4469 target.c: New file, routines to handle transfer vector.
4470 (various files): Add transfer vectors XXX_ops for the various
4471 targets and pseudo-targets (core files, etc) we support.
4473 * breakpoint.c (bpstat_stop_status): Further explorations of
4474 watchpoints and why things don't work all the time.
4475 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4477 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4478 the local gdbinit if it doesn't already have it.
4480 * core.c (core_ops): add and install.
4481 Allow core debugging without exec file.
4483 * dbxread.c (free_and_init_header_files): Merge two fns.
4484 (end_symtab): Free named symbol table when a new version comes in.
4485 (read_dbx_symtab): Relocate all kinds of symbols with base
4486 address. First step toward handling different text, data, bss
4488 (add_file_addr_command): Renamed add_file_command.
4489 (add_file_command): Vector to remote handler.
4490 Add "load" as an alias for "add-file" command.
4492 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4493 non-returning functions.
4495 * exec.c: Add exec_ops, and push it as a target when an exec
4498 * infcmd.c (run_command): Pass executable file name and arg list
4499 separately when starting an inferior. Permit "run" when no exec
4500 file is specified, for VxWorks.
4501 (detach_command): Move to child_detach in inftarg.c.
4503 * inftarg.c: New file. Unix-child-specific routines, and the
4504 child_ops structure.
4506 * inferior.h (registers): Export "registers" as the way for
4507 target dependent register handlers to find gdb's local copy of
4508 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4509 since it is now used by places that want wait_for_inferior to
4510 handle the grunge but want to see every trap from the inferior.
4512 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4513 Eliminate remote_debugging hooks in terminal handling.
4515 * infrun.c: Replace start_inferior with child_create_inferior.
4516 Move all the hair of Unix shells and ptrace idiosyncracies into
4517 child_create_inferior, so remote handlers don't have to deal.
4518 Remove running_in_shell. Rename stop_after_attach to
4519 stop_soon_quietly, and use it in a few other places where we want
4520 to just call wait_for_inferior and get control back on the first
4521 trap. trap_expected now never takes a value > 1.
4522 (init_wait_for_inferior): Initialize static vars when a new
4525 main.c (gdbinit): Add new hook for .gdbinit file name, let
4526 it be overridden by config files as GDBINIT_FILENAME.
4527 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4528 Both of these are used for VxWorks gdb.
4530 mcheck.c: rename include file "gmalloc.c" to avoid problems
4531 with system include file "malloc.c".
4533 param-no-tm.h: New include file, same as param.h but does not
4534 include the default "tm.h" file. This is used in files where
4535 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4537 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4539 remote-vx.c: New file, VxWorks remote debugging support. Uses
4540 RPC routines that are shared with the target system, in directory
4543 remote.c: Vectorize remote interface.
4545 source.c: Globalize source_path, and make an alias "l" for "list"
4546 since we now have the "load" command.
4548 sparc-xdep.c: Use new param-no-tm.h.
4550 symmisc.c (free_named_symtab): Add new function from Wind River.
4551 However, ifdef it out for now while we think about what it should
4554 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4556 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4557 non-Unix-children handle this with their own code in the target
4560 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4561 source and target lists. Add vx-share to default list of include
4562 directories. Add new files to src and target lists: mem-break,
4563 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4564 ${srcdir} versions of munch and createtags are used.
4566 * valops.c (find_function_addr): Split out of call_function.
4567 (call_function_by_hand): Rename call_function; this function
4568 calls functions in the target by laboriously patching the target
4569 word-by-word with the right stack, args, regs, etc.
4572 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
4574 Handle AMD 29000 a bit better.
4576 * remote-eb.c (readchar): Mask received char log to make it readable.
4577 (remote_start): Pass arguments down to executing program.
4578 Make startaddr unsigned.
4579 infrun.c (start_inferior): Accept args, pass them to
4581 infcmd.c (run_command): Pass args down to start_inferior.
4583 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
4584 the target object file format.
4585 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
4587 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
4588 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
4590 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
4592 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
4593 * TODO: We did a few things, we have more to do though.
4595 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
4596 * inflow.c (inferior_died): Clear deferred stores.
4598 * Debug problems with dummy frames and calls to the inferior.
4599 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
4600 * sparc-tdep.c (do_restore_insn): Simplify.
4601 (sparc_frame_find_saved_regs): Simplify and fix what we find.
4602 (sparc_push_dummy_frame): Simplify and fix what we push.
4603 (sparc_pop_frame): Slightly more hair here, deciding whether
4604 we are restoring a saved PC or returning to a return address in %i7.
4605 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
4607 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
4608 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
4609 * obstack.h (chunkfun): ditto.
4610 * defs.h (xmalloc, xrealloc): ditto
4612 * utils.c (quit): Grab the terminal from the child if necessary.
4614 * inflow.c (term_status_command): Rename to term_info, change
4617 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
4618 (is_delayed_branch): Speed up.
4619 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
4620 Still missing some float ops, and needs testing.
4622 * Support for input and output radixes other than base 10
4623 * defs.h (input_radix, output_radix): Declare.
4624 * expread.y (yyparse, parse_number): Handle changes of input
4625 radix, and ambiguous names-or-numbers in radixes >10.
4626 * printcmd.c (print_scalar_formatted): Print formatted hex
4627 numbers in varying column widths.
4628 * valprint.c (val_print): Use output_format to print scalar ints.
4629 (set_input_radix, set_output_radix, set_radix): Create.
4630 (set_output_radix): Set output_format from output_radix.
4631 (_initialize_valprint): add `set radix' but leave the others off.
4633 * main.c (execute_command): Let stupid questions be turned off.
4634 (_initialize_main): Handle "set stupidity", etc.
4636 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
4637 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
4639 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
4641 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
4642 bfd stuff is still screwed up, but with some manual work, it
4645 * breakpoint.c (bpstat_do_actions): Start over if a command
4646 proceeds the inferior, since the inferior will have stopped and
4647 will need to have its new stop-actions taken care of.
4649 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
4650 compiler fits, simplify it.
4652 * gdb.texinfo (directory command): Doc new dir command.
4653 source.c (directory_command): "dir" now puts things on the front
4654 of the path, moves dups up front, and handles multiple names
4655 on the command line, inserting each one in order. It also
4656 blows away cached line and full_filename info.
4658 * stack.c (backtrace_command): Skip "more stack frames follow"
4661 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
4662 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
4663 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
4664 The only odd one was Gould NP1, which had defined vprintf to
4667 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
4668 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
4669 variable, inspect_it.
4670 valprint.c (print_string, val_print): Use the global inspect_it
4671 to indicate whether to print in Epoch style or normal style.
4673 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
4675 * printcmd.c (call_command): add an alias for the "print" command
4676 which runs expressions and doesn't print the result if void.
4677 (print_command_1): implement it.
4679 * command.c: Remove #if 0'd code. Initialize all the fields
4680 in add_cmd (). Rename do_nothing_command to
4681 not_just_help_class_command, and make it externally visible.
4682 command.h: add user_commands to struct.
4683 * main.c (define_command): Don't overload c->function with a char
4684 string as well as a function pointer.
4686 * eval.c (evaluate_subexp): Reinstall tiemann changes to
4687 calling convention of value_struct_elt () that got dropped in
4690 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
4691 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
4693 * tm-sparc.h (POP_FRAME): replace some constants with defines.
4695 * sparc-xdep.c (store_inferior_registers): defer stores to regs
4696 until a good time (e.g. when we are about to run the child),
4697 saving ptrace calls.
4698 * infrun.c (proceed): handle DO_DEFERRED_STORES.
4699 * tm-sparc.h: define DO_DEFERRED_STORES.
4701 * sparc-xdep.c (store_inferior_registers): when storing float
4702 registers, don't store stack regs too. When storing the SP,
4703 however, DO store the stack regs too. This fixes a bug in which
4704 the dummy frame is not recognized when a call_function finishes,
4705 because its frame pointer (in the stack regs) was never
4707 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
4708 even though we don't know how to read them from an inferior.
4709 valops.c (call_function): Comment about storing SP.
4711 * infrun.c (save_inferior_status): Save away the original bpstat
4712 chain so it can be restored later. Install the copied version for
4713 use by whoever saved the status. It will be blow away by
4714 restore_inferior_status, and the original chain restored. This is
4715 important for people who have pointers into the original.
4717 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
4718 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
4719 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
4722 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
4724 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
4725 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
4726 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
4728 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
4730 * Merge Mike Tiemann's multiple inheritance changes from Sun.
4731 Store the baseclasses in a type struct starting from array element
4732 0 rather than from the unusual array element 1.
4734 dbxread.c: the above.
4735 (virtual_context): Add
4736 Read new debug information about which virtual function table
4737 a virtual function is from, and store it in fn_field.fcontext.
4739 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
4740 TYPE_FN_FIELD_STATIC_P.
4742 symtab.c: the above.
4743 valops.c: the above. Handle pointer casts of object *'s.
4744 (search_struct_method): Add.
4745 (value_struct_elt): First arg is now a pointer to a value, and is
4748 valprint.c: the above.
4749 values.c (value_virtual_fn_field): Add type arg. Handle
4750 offsetting to the proper object when calling virtual fns.
4752 (baseclass_addr): Add valuep arg.
4754 * README: Document the current state of BFD config (missing).
4755 * TODO, ChangeLog, Makefile.dist: Roll version.
4756 * WHATS.NEW: Add summary of changes since 3.5.
4758 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
4760 * dbxread.c (read_struct_type): Clear bit vectors whenever
4762 symtab.c (B_CLRALL): define.
4764 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
4765 using == rather than =. Huh... This fixes the dreaded problem
4766 wherein builtin_type_int becomes TYPE_CODE_FLT.
4768 * core.c (info_files): Show the inferior pid.
4770 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
4771 already knows how to look in the source directory.
4773 * Remove psymtab hair from many places. Remove duplicated code
4774 for searching symbol tables. Hide psymtabs from most places.
4775 Make it fast to get from a psymtab to its symtab.
4777 blockframe.c (blockvector_for_pc): Remove psymtab hair.
4778 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4779 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4780 dbxread.c: export psymtab_to_symtab, make it work if called N times.
4781 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
4782 new symtab completely. New psymtabs get symtab pointer
4783 initialized to zero. Remove MI warning printf.
4784 symtab.h: Comments. Add psymtab to symtab pointer.
4785 (PSYMTAB_TO_SYMTAB): New macro.
4786 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
4787 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
4789 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
4791 (print_frame_info): Avoid special-casing symbols that have not yet
4794 * source.c (open_source_file): Quick path if we have already
4795 located the source file by its full name.
4797 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
4798 find_pc_psymtab. When a name is found in the misc function
4799 vector, search the symbol table for its mangled name, not the
4800 name that the user typed.
4802 * bfd.h: Fix missing comment terminators, make #endifs match.
4804 * valarith.c (value_less): Handle unsigned int comparisons.
4805 Add FIXME about pointer compares, which assume host and target
4806 pointers are the same.
4808 * command.c (do_nothing_command): lint
4809 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
4810 fix comments on debug symbol format for visibility. Actually set
4811 visibility of symbols.
4812 main.c (echo_command): lint; use <readline/history.h>.
4813 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
4814 obstack.h (_obstack_blank): Rearrange pointer math to avoid
4815 pointing past end of allocated memory; saber complains.
4816 obstack.h: Declare the external functions that we use.
4817 valarith.h: use <string.h>
4818 solib.c (solib_add): lint.
4820 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
4822 * main.c (initialize_main): Default info_verbose to off, now that
4823 symbol reading is fast.
4824 (quit_command): Avoid clobbering exec_bfd while quitting.
4826 * Initial BFD (binary file diddling library) merger:
4827 coffread.c: Change AOUTHDR to struct exe_hdr.
4829 core.c: initialize initialized data at compile time.
4830 (core_file_command): Move from coredep.c, convert to bfd.
4831 (xfer_core_file): Convert to bfd.
4832 exec.c (exec_file_command): use bfd routines.
4834 mips-tdep.c: Remove exec_file_command and friends.
4837 * coredep.c: (fetch_core_registers) Convert core_file_command to
4838 fetch_core_registers.
4839 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
4841 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
4842 (my_bfd_read): More bogosity, which I don't think we call.
4843 (program_name): Remove this atrocity asap!
4845 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
4848 values.c: allocate_repeat_value was not clearing the
4849 optimized_out field.
4850 (value_static_field): minor stylistic fix (wrong macro was used).
4851 valops.c (value_struct_elt_for_address): didn't work for C++
4854 * signame.c (_initialize_signame): Initialize signal names once.
4856 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
4857 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
4858 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
4860 * remote-eb.c: Support user-settable baud rates on the serial port.
4862 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
4864 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
4866 * tconfig/sun3os4: Remove warning about native assembler,
4867 since it also occurs in the xconfig file.
4869 * findvar.c (registers): Allocate some slop after `registers'
4870 to prevent stray accesses from trashing the next variable.
4872 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
4873 on the sun-3, by changing the #ifdef from `sun3' (which is not
4874 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
4875 vars, which happened to follow `registers' in the executable.
4877 * readline/history.c (history_search): Heed gcc-2's advice
4878 and parenthesize && inside ||).
4880 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
4881 tm-29k.c: Insert FSF copyright headers.
4883 * remote-eb.c: Better comments.
4885 * Makefile.dist: Update to 3.91.6.
4886 * TODO: note PREPARE_TO_STORE problem.
4888 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
4890 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
4892 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
4894 * infrun.c (wait_for_inferior, at end): Don't set up
4895 prev_* if the inferior no longer exists.
4897 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
4898 CANNOT_EXECUTE_STACK.
4899 valops.c (call_function): Use it.
4901 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
4903 * inferior.h (PC_IN_CALL_DUMMY): New macro.
4904 infrun.c (wait_for_inferior, 2 places): Use it.
4906 * values.c (value_being_returned): Only use
4907 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
4909 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
4910 right thing for remote-eb.c.
4912 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
4913 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
4915 * blockframe.c: Put get_frame_saved_regs inside #if !defined
4916 (FRAME_FIND_SAVED_REGS).
4918 * findvar.c ({fetch,store}_registers): Check for
4919 REMOTE_{FETCH_STORE}_REGISTER macro.
4921 * findvar.c (get_saved_register): Add argument lval and
4922 change meaning of argument addr.
4923 findvar.c: Change calls to get_saved_register to reflect
4924 new calling convention.
4925 valops.c (value_assign): Use get_saved_register instead of
4926 find_saved_register.
4928 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4930 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
4931 an (uninitialized) pointer to one. Use "&" when passing it
4934 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4936 * coffread.c (getfilename): Use DGUX x_offset and x_name if
4939 * coffread.c (symbol_file_command): Put semicolon after
4941 Put safe_to_init_tdesc_context in #if defined (TDESC).
4942 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
4943 coffread.c: #include <sys/stat.h>.
4944 (read_coff_symtab): Typo: in_source_files -> in_source_file.
4945 Add missing ')' in check for "lc%" and friends. Remove
4947 Declare read_one_sym() at top of file.
4948 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
4949 MC68WRMAGIC can have the same value without causing a duplicate
4952 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
4954 * Allow a Makefile to be built without building the
4955 tm and xm file links that screw up builds in subdirectories.
4956 This is done with `config.gdb none', then you can do things
4957 like `make gdb.tar.Z'.
4958 * tconfig/none: Config file for no target system
4959 * xconfig/none: Config file for no host system
4960 * config.gdb: If no TM or XM files are called out by the
4961 host or target file, don't make links for them.
4963 * cplus-dem.c: Add documentation.
4965 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
4966 simple error, so the user's gdb doesn't crash due to some object
4967 file problem (e.g. somebody is rebuilding the file out from under
4970 * printcmd.c (print_address_symbolic): demangle the symbol.
4972 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
4973 Motorola copyrights in it. Make "make gdb.tar.Z" work.
4974 (alldeps.mak): sort and uniq all results from this; duplicates
4975 hose gdb.tar.Z link building. Remove RCS files from
4976 tconfig and xconfig. Add config files for sun386. Add
4977 a few odd files to OTHERS and HFILES.
4979 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
4981 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
4982 Roll version number to 3.91.5. Make lint work in bindir.
4984 * README: Document cross-debugging and new file structure.
4986 * blockframe.c: Lint. Include "value.h" to declare read_register.
4987 (find_pc_partial_function): remove duplicate line.
4989 * command.h: Lint. Declare error_no_arg and dont_repeat.
4991 * tm-news.h: Remove inadvertently duplicated stuff.
4993 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
4994 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
4996 * config.gdb: Allow `config.gdb host target' form. Clean
4997 up previous change that printed bogus messages when you just said
5000 * core.c: #include "command.h" for lint.
5003 * main.c: Remove some casts of enums. Lint.
5010 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5012 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5013 read it from memory. This will allow us to save ptrace calls
5014 eventually. Changed caller single_step too.
5016 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5017 that we aren't going to use, saving many ptrace calls, especially
5018 when watchpointing or single stepping. Use some #define's for
5020 (store_inferior_registers): Ditto.
5021 (core_file_command): Use some #define's for constants.
5023 * tm-sparc.h: Add #define's for some register numbers, so we
5024 can eliminate the use of random constants in sparc-xdep.c.
5026 * stack.c (frame_command, print_frame_info, up_command,
5027 down_command) Remove frame_changed, since it
5028 causes a bug and doesn't seem to do anything useful. In some
5029 places it was used as a flag, in others as a stack level (?).
5031 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5032 default is to use the portable (vprintf) version rather than the
5034 * xm-news.h (MISSING_VPRINTF): Add.
5036 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5038 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5040 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5041 about linking debugged programs -Bstatic in the sun?os4 config
5042 files in tconfig and xconfig subdirectories.
5044 * main.c (main): Remove unreached exit(0) now that we exit
5047 * Create TODO file for online bug list. There are too many
5048 "little" bugs to keep track of on paper.
5050 * Change Projects file to refer to bug-gdb@cygnus.com
5051 rather than kingdon@ai.
5053 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5055 * Makefile.dist (VERSION): 3.91.4 now.
5057 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5058 (condense_misc_bunches): Add sanity check that misc_count is
5059 the same as the number of symbols in the bunch.
5061 * coffread.c: rename init_misc_bunches. Pass an argument
5062 to condense_misc_bunches (a zero).
5064 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5065 every time we are called; don't rely on our caller to do it.
5066 (add_file): Remove call to init_misc_bunches.
5068 * mipsread.c: Only warn, don't error, if unknown symbol types.
5069 This keeps an old gdb from falling on its face if it sees newly
5070 extended symbol info. Rename init_misc_bunches.
5072 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5074 * Merge in changes from Per Bothner for DECstations and other
5075 MIPS stuff. The rest is Bothner speaking:
5077 The next message is a merger of Alessando Forin's mips port with
5078 mine. I've tried to use my good if biased judgment to get
5079 the best of both. It *does* need testing.
5081 Some of the changes are general, *not* mips-specific.
5084 Didn't believe in little-endian bit order.
5085 There are still inconsistencies about whether flags
5086 like BITS_BIG_ENDIAN are integer (#if ...) or
5087 boolean (#ifdef ...). I tried to paper over them.
5089 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5090 Moved some misc_function code that was common to
5091 {dbx,coff,mips}read.c to symtab.c.
5092 In the process, I think I cleaned things up a bit.
5093 At the same time, moved obsavestring and obconcat to symtab.c.
5096 Removed obsolete condense_addl_misc_bunches (use
5097 condense_misc_bunches(1) instead).
5100 Needed to include <sys/dir>, at least on DECstations.
5102 valops.c, mips-tdep.c, tm-mips.h:
5103 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5104 conventions (when STACK_ALIGN is insufficient).
5105 Needed on mips, where doubles need 8-byte alignment,
5106 but ints only need 4.
5109 Removed cruft that was not being used.
5110 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5113 Print $ before register-names (I think that makes things a little
5115 Never print two instructions, even if one delays.
5116 Removed hex-disassemble set_cmd. (This is not mips-specific,
5117 so I think the argument is whether it is generally worthwhile or not.
5118 I'm inclined to think not, given how easy it is to
5119 convert between radixes in gdb.)
5122 This is basically Alessando's code.
5123 It doesn't use obstacks; I changed it to use obstacks
5124 in a few minor places where using malloc causes a
5125 memory leak. (Probably, more places could/should be changed.)
5126 I added record_misc_function where it was missing.
5127 In symbol_file_command and add_file_command, I tried
5128 to make the code consistent with more recent versions.
5129 Minor sylistic changes in parse_procedure.
5130 Make a .gdbinfo. psuedo-symbol point back to the real
5131 procedure symbol (using the isym field).
5134 This is basically from my port, but with a lot of details
5135 and a number of routines merged in from Alessando's version.
5136 I basically used my code "raw" backtrace (use heuristics
5137 from the actual code, rather than symbol table info) - though
5138 the idea is Alessandro's. I feel my code is a little cleaner
5139 here, particularly in being a little more flexible, such as being
5140 able to handle gcc-produced code (which it now can).
5141 It also doesn't do frame caching (which is not useful
5142 more recent gdb versions).
5143 I also used my code for push_/pop_dummy, more or less.
5144 I tried to incorporate AF's code for testing sigtramp
5145 while backtracing; I probably got it wrong.
5146 Added mips_print_register, which tries to scrunch as much
5147 information as possible on a screen...
5148 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5149 under mips-pinsn.c), I don't see anything mips-specific here,
5150 and I don't see it being all that useful anyway.
5153 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5154 Use more register names (rather than hard-cases numbers).
5156 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5158 * Hack up 3.90.11 changes:
5160 * Makefile.dist (depend): parameterize $(GCC).
5161 Add solib.c and solib.o.
5162 (readline): Fix vpath for both absolute or relative SRCDIR.
5164 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5165 Also, let the part I didn't understand at least compile so
5166 I can test the rest. FIXME.
5168 * dbxread.c: Fix thinko using strcmp.
5169 (init_psymbol_list): declare static.
5170 (partial_symbol_file_open): Comment cleanups better, avoid
5171 cleaning up the string table since the caller will do that.
5172 Move the stat for mod time into symbol_file_command, temporarily.
5173 (There should be a mod time for each symbol file, eventually,
5174 to control its rereading. FIXME.)
5176 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5177 SunOS, which gives error for shared libs otherwise. (From
5178 Schaefer, probably FIXME needs work for portability.)
5180 * solib.c: Move #include "param.h" to work.
5181 Lowercase all the Uppercase Letters In the Messages.
5182 (find_solib): Clean up inferior_so_name for debug printouts.
5183 Allow no argument, to mean all shared libraries.
5185 * symmisc.c: include param.h to get CLEAR_SOLIB.
5187 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5189 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5190 to 3.90.11. ChangeLog entries below are from this.
5192 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5196 * Makefile.dist (HFILES): Add tm-sunos.h.
5198 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5202 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5204 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5206 * sparc-opcode.h Added single-operand version of rett.
5208 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5210 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5211 Put parens around gcc_p in expansion.
5213 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5215 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5217 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5219 * Changes for Sun shared libraries:
5220 blockframe.c (find_pc_partial_function): If a non-text symbol
5221 is found, set *address = pc - FUNCTION_START_OFFSET.
5222 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5223 Disable breakpoints instead of giving an error.
5224 source.c (select_source_symtab): Initialize cs_pst.
5225 symmisc.c: Call CLEAR_SOLIB if defined.
5226 symtab.h: Make text{low,high} CORE_ADDR not int.
5227 (psymtab): New field addr.
5229 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5230 (record_misc_function): Give correct type for N_DATA symbols.
5231 (condense_misc_bunches): do "misc_function_count = j" regardless
5233 Take code which is shared between symbol_file_command and
5234 add_file_command and put it into partial_symbol_file_{open,read}.
5235 Split add_file_command into add_file_command and add_file.
5236 Make psymtab_to_symtab read in the string table if the file
5238 Two new parameters to read_dbx_symtab and start_psymtab.
5239 tm-sunos.h: New file.
5241 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5243 * infcmd.c: Change cont_command to continue_command and "cont"
5246 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5248 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5250 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5252 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5253 size 1,2,4,8 rather than size < 8.
5255 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5256 as necessary, not just once.
5258 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5260 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5262 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5264 * tm-news.h: Add CALL_DUMMY_*.
5266 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5268 * config.gdb: In list_host, list_target, use ${i}, not $i.
5270 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5272 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5274 * sparc-opcode.h: Change all store floating-point state register
5275 instructions to have the right match & lose fields.
5277 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5279 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5281 config.gdb: If srcdir != ., create readline directory and
5282 copy a makefile into it.
5284 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5285 consistency with POSIX.
5287 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5288 when we exit its exp_valid_block.
5290 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5292 * Makefile.dist: Bump version to 3.91.3.
5294 * Clean up handling of breakpoint commands (somewhat).
5295 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5297 inferior.h: Add breakpoint_proceeded to inferior status struct
5298 and globals; save it and restore it.
5299 (clear_breakpoint_commands): Cleanup, remove old #define.
5301 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5302 (save_inferior_status, restore_inferior_status): handle it also.
5303 (proceed): Remove earlier code that set breakpoint_proceeded.
5304 It is now set only in clear_proceed_status.
5305 (clear_proceed_status): Cleanup, use bpstat_clear rather
5306 than clear_breakpoint_commands. No callers need the stop_bpstat
5307 between clear_proceed_status and proceed.
5309 infcmd.c: Add breakpoint_proceeded definition and comment.
5310 (cont_command, jump_command, signal_command): Move call to
5311 clear_proceed_status right next to call to proceed.
5313 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5314 caller's argument while running down the chain of breakpoints.
5315 Use new variable "breakpoint_proceeded" to determine when
5316 a command that it executes moves the inferior past the
5318 (bpstat_clear): Handle NULL argument.
5319 (bpstat_clear_actions): Avoid useless call to
5320 breakpoint_auto_delete.
5321 (delete_breakpoint): Clean up bpstat's that are pointing to
5322 the deleted breakpoint from the stop_bpstat chain.
5323 (breakpoint_auto_delete): Simplify.
5325 * Clean up handling of EOF, error on stdin, etc. This was
5326 prompted by a network problem that caused gdb to go into an
5327 infinite loop filling up its malloc'd memory.
5329 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5330 not clear_breakpoints_commands, which is now gone.
5331 (main): If command_loop returns (e.g. from EOF on stdin), do
5332 a quit_command (looping back to command_loop if quit_command
5333 doesn't really quit).
5334 (command_loop): check result from command_line_input and
5335 exit if it returns NULL, rather than passing the NULL to
5337 (gdb_readline): Free malloc'd result space before returning
5340 * utils.c (query): Handle C-d to mean "yes", just as if the
5341 input was not a terminal. Also avoid infinite loop if EOF
5342 occurs in mid-input-line before newline. This allows
5343 query to be used at EOF on stdin with reasonable results.
5345 * infrun.c (proceed): Set breakpoint_proceeded.
5347 * values.c (value_as_long): Avoid infinite recursion for enums.
5348 (_initialize_values): Fix typo in help msg (kingdon).
5350 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5351 RL_LIB for linking. This allows -lreadline for linking
5352 and nothing for dependencies, once readline is a real library.
5354 * config.gdb: Jim Kingdon: give useful error message if the
5355 host or target type is not recognized.
5357 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5358 it just defines it. Dumb, but deal with it.
5360 * Jim Kingdon suggests:
5361 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5363 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5365 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5367 * Clean up Bothner's changes.
5369 * blockframe.c (clear_pc_function_cache): New function.
5370 * blockframe.c: remake cache_pc_function_* static.
5371 * dbxread.c (symbol_file_command): remove references to
5372 cache_pc_function_* variables.
5373 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5374 * printcmd.c: Avoid kludging a global variable (addressprint)
5375 to avoid printing the address of a string twice. Instead,
5376 pass the format letter 's' down low enough that it can be seen
5377 to avoid this problem.
5378 (print_formatted): Pass format arg to value_print.
5379 (restore_addressprint): Remove function.
5380 (do_examine): Avoid hacking addressprint, cleanups and such.
5381 (print_frame_args): Add a comment to a Bothner change.
5382 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5383 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5384 to wipe out the values cached in blockframe.c.
5385 * symtab.c (find_method): Add comment saying how big you must
5386 allocate to be "big enough". Per being terse again.
5387 * valprint.c (val_print): Handle format letter "s" to print
5388 strings without addresses. Add comment to vtbl printing code
5389 which casts with wild abandon. Rearrange reference-printing
5391 @0xaddr: value (print w/addressprint)
5392 value (print w/~addressprint)
5393 @0xaddr (parameter lists w/addressprint)
5394 or nothing (parameter lists w/o addressprint)
5396 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5398 * Merge more changes from Per Bothner:
5400 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5401 annoying) that I tried to improve it. Here are my suggestions.
5403 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5406 Do automatic de-reference when taking the address of a reference.
5408 Don't deref_ref when printing parameter lists.
5410 More attempts at treating refernences properly.
5412 In val_print, if deref_ref==0, don't print dangling " = ".
5414 Add COERCE_REF macro, which de-references an REF.
5416 * Merge changes from Per Bothner:
5418 * Fixed (Sony news)-specific configuration problems.
5419 * Fixed other problems with using vanilla pcc and libc (enum problems;
5420 assumption that vsprintf exists).
5421 * Some major speed-ups (finc_pc_partial_function now caches a match;
5422 parsing avoids duplicate symbol_lookup calls).
5423 * Changed handling of baseclasses (no longer use baseclasses field
5424 of struct type, use the first n_baseclasses fields instead).
5425 * Various minor changes/fixes, most C++-related.
5428 Cache the most previous match from find_pc_partial_function.
5429 (Save both low and high ends of matching function's pc range.)
5430 This speeds up the loop of infrun.c:wait_for_inferior quite
5431 a bit, and makes step/next commands much zippier.
5433 Added an enum->int cast (otherwise, some compilers barf).
5435 No longer set baseclass offset to 0, since multiple
5436 inheritance now mostly works.
5437 Added a number of casts, to shut up compiler warnings
5438 (after stabs where made enums, not ints).
5439 When discarding a symbol table (in symbol_file_command),
5440 must clear the cache introduced in blockframe.c.
5441 Don't convert $vtbl_ptr_type to vtbl any more.
5442 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5443 Mask off sign bit emitted by g++ for virtual table offset.
5444 Set voffset to -1 (not 1) for static member functions.
5446 Changed parsing/lexing of names to avoid doing symbol lookup twice
5447 (once when lexing to determine symbol class, once for real).
5448 Now only call symbol_lookup once. Fields of 'this' win especially big.
5450 Subpress printing addr twice in the case of 'x/s addr'.
5452 lookup_basetype_type is no longer used.
5453 Add find_methods as recursive helper function to decode_line_1.
5454 This allows multiple inheritance to work.
5455 Also, once one or more matches has been found, do not look in
5456 base-classes. (Baseclass methods would be overridden, anyway.)
5458 Removed baseclasses array in struct type.
5459 Instead of using baseclasses[i], use fields[i-1].
5460 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5461 Changed sign convention of voffset (previous was inconsistent).
5463 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5465 Used to assume existence of vsprintf. Re-written to not need it
5466 if HAVE_VPRINTF is undefined.
5468 typecmp was too pessimistic. Made it less so.
5470 Don't print space after address.
5471 If vtable points to a misc symbol (with 0 offset), print it,
5472 since that indicates the actual class of the object.
5473 Changed ype_print_derivation_info to use new inheritance
5474 scheme (without baseclasses vector).
5476 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5477 Also, changes needed because TYPE_BASECLASSES were removed.
5479 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5481 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5484 If there is no path set, and the symbols don't indicate what directory
5485 a file was compiled in, look in the current directory. But either
5486 a path or a known compilation directory will prevent this.
5489 Three independent bug fixes:
5490 * Remove the #if 0 block that breaks some stuff.
5491 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5492 adapt gdb to either SunOS 4.0.* or 4.1.
5493 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5496 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5499 (type_print) Demangle the name being printed.
5500 (type_print_base) Handle botched demangling without coredump (tiemann).
5503 (check_stub_method): Document routine.
5504 (tiemann) fix bug for no-arg functions
5505 Avoid clobbering beyond end of malloc'd storage.
5506 Terminate the argument list properly.
5508 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5510 * Changes merged by John Gilmore:
5513 In breakpoint_1, use new print_address_symbolic instead
5514 of find_pc_partial_function. (This forces use of assembler-level
5515 addresses, and avoids misleading non-mangled source-level names.)
5517 Generalize ansi argument such that -1 means skip arglist totally.
5518 Removed global variable print_ansi_qualifiers (which made
5519 code non-reentrant), in favor of extra explicit arguments
5520 to internal routines.
5522 Add new helper function print_address_symbolic.
5523 Use find_pc_misc_function instead of find_pc_partial_function
5524 (since we want assembler-level symbols here).
5526 Print unknown function as just "f (...)", not "f (...) (...)".
5527 Use new fputs_demangled explicitly.
5529 Fixed a typing violation (problem: value.h cannot be imported
5530 without renaming many variable in this file).
5531 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5532 decode_line_1: Moved forward some never-reached code.
5533 Made decode_line_2 skip function prologues correctly.
5535 fputs_filtered should not demangle by default.
5536 Add new fputs_demangled to demangle on demand..
5538 Change value_struct_elt to use value_primitive_field (using recursive
5539 utility function search_struct_field). This allows foo.bar to work
5540 for multiple inheritance (so far only for data fields).
5541 Change check_field in the same way (recursive helper function
5542 to support multiple inheritance).
5543 (Note: there are more of these problems that I haven't fixed.
5544 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5545 value_of_this: 'this' symbol name is now just "this", note "$this".
5547 Don't print static members.
5548 Avoid printing "members of <type>" if there are none.
5549 Simplified type_print_derivation_info by merging duplicate code.
5550 Remove useless blank lines in type_print_base (ptype command).
5552 Added declaration of new routine value_primitive_field.
5554 Added value_primitive_field which is generalized version of
5555 value_field that can handle multiple inheritance (non-zero offsets etc).
5556 Re-implemented value_field to call value_primitive_field.
5558 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
5560 * infcmd.c -- insert else to avoid 'delete env' coredump when you
5561 delete the whole environment. Karl Berry reported the bug.
5562 * source.c - fix openp to avoid //'s in filenames, which
5563 trigger an Emacs bug causing it to not be able to find files
5564 when running gdb in a window.
5565 * dbxread.c - zap the #if 0 that botches the add-file code.
5566 It seems to work a lot better without all the code commented out.
5568 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
5570 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
5573 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
5575 * Makefile - added a ${CFLAGS} to a couple of entries,
5576 added remote-sa.sparc.c
5577 * added remote.sa-sparc.c, a modification of remote.c
5578 which conducts a dialog directly with the SparcStation prom.
5579 * breakpoint.c, infrun.c, sparcdep.c added
5580 remote_insert_breakpoint(), and remote_remove_breakpoint()
5581 to breakpoint.c instead of directly writing breakpoint instructions.
5582 * sparcdep.c on remote_debugging,there is no need
5583 to remove signle step breakpoint instructions.
5584 * main.c added "-epoch" flag and "int epoch_interface" to main.c
5586 * printcmd.c - epoch interface sends lisp expressions to open up
5587 epoch windows on inspection.
5588 * valprint.c - added arrayprint, and addressprint and made adding
5589 format controls easier
5590 * wait.h added a couple of undef's because we were getting
5591 complaints about WSTOPSIG and WTERMSIG begin redefined.

5661 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
5662 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
5663 when printing the type.

5687 step_resume_break_address != NULL, even if another_trap.
5688 If trap_expected and we enter sigtramp, then set up a
5690 If trap_expected is set when we hit the step_resume_break,
