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

76 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
77 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
79 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
81 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
82 * mips-xdep.c (store_inferior_registers): Don't try to
83 write the (pseudo) FP.
84 * mipsread.c (parse_partial_symbols): Improved algorithm for
85 setting pst->texthigh.
87 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
89 * doc/Makefile: make TEXINPUTS include . everywhere
91 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
93 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
94 vestiges of typevectors, which were for symsegs and are no longer
95 used. (From a question by Eliot Dresselhaus
96 <dresselh@RFT30.nas.nasa.gov>).
98 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
100 * dbxread.c, coffread.c: static-ize functions that were
101 gratuitiously external. (From Fred Fish.)
103 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
105 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
106 until it is large enough.
108 * dbxread.c (read_type): Handle error case slightly better.
109 Make complaint message not C++-specific.
111 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
113 * infrun.c (wait_for_inferior): Fix step/next so that you only
114 stop at the beginning of a new line. This fixes various problems
115 with for loops, nested if-else's and switch statements.
117 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
119 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
120 between symtabs and psymtabs become ordinary error()s.
122 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
123 properly, making "end pc" correct in shared lib psymtabs.
124 (From Guy Harris <guy@auspex.com>.)
126 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
128 * dbxread.c: Enable, but soften, const_vol_complaint.
129 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
130 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
131 should be file-scope, not global.
132 (read_struct_type): Remove ancient multiple-inheritance warning.
133 (read_range_type): Check base type, complain & patch if undefined.
134 * stack.c (frame_info): Demangle the function name in `info stack'.
137 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
139 * eval.c (evaluate_subexp_for_address): Don't use
140 TYPE_POINTER_TYPE directly (it might be zero if this type has
141 never had a pointer created before); use lookup_pointer_type.
142 * symtab.c (lookup_method_type): Arguments were swapped in all
143 callers, so fix it here. I'm amazed this worked at all!
145 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
147 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
148 "bss" rather than "data" symbols, but which still conflict.
151 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
152 * core.c (core_files_info): Shorten output.
153 * exec.c (exec_files_info): Ditto.
154 (build_section_table): Ignore zero-length sections.
155 * language.c, printcmd.c: Lint.
156 * language.h (get_frame_language): Declare.
157 * saber.suppress: update.
158 * stack.c (find_relative_frame): Remove complex code that was
159 #if 0'd, stick with simple code. Lint.
160 * saber.suppress: Update a bit.
161 * symfile.c (add_symbol_file_command): Add "?" to question.
162 * utils.c (parse_escape): Avoid \a due to bdead compilers.
163 * value.h: Declare typedef_print.
165 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
168 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
169 (Reported by Mark Peek <mark@imagen.com>.)
171 * solib.c (solib_map_sections): Relocate all sections, even
172 though only the text section's size is tracked. Mark ld_text
173 for eventual elimination as we generalize to N sections.
175 * infrun.c (wait_for_inferior): Don't check if the PC is in a
176 call_dummy if we were stopped by a random signal that is being
177 passed to the program. This produced wierd results when calling
178 functions in the inferior and signals (e.g. SIGALRM) were in use.
180 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
182 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
183 Bugfix from Paul Eggert <eggert@twinsun.com>.
184 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
185 * valprint.c (print_floating): Print 9 digits for IEEE floats.
188 Mon Sep 23 15:50:07 1991 John Gilmore (gnu at cygnus.com)

194 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
198 * Makefile.in (VERSION): Set to 4.1.
199 * language.c (set_language_command): Print useful help message,
200 and restore the language string after giving help.
201 * valprint.c (typedef_print): Print typedef in C or M2.
202 * symtab.c (list_symbols): Use it.
203 * main.c (main): Avoid any output before (gdb) prompt when -q.
204 * language.c (set_language_command): Handle errors by restoring
205 the language string to its current state (fix from A. Beers).
206 * doc/gdbint.texinfo: Roll in information from README. Rearrange
207 "how to install" and "how to print the doc" stuff so it drops
209 * configure.in: Rename rtpc CPU to romp to match config.sub.
210 * README, WHATS.NEW, TODO: Update for gdb-4.1.
212 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
214 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
215 autoloading shared libs, copyright etc on GDB startup, clean up $_
216 and $__ index refs, set/show listsize and related updates to list
217 cmd. New host/target configs.
219 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
221 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
222 from main Makefile.in version definition
223 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
225 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
227 * doc/gdb.texinfo: merge new language-switching and lang-specific
230 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
232 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
233 compilers (which may lack stddef.h).
235 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
237 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
238 N_WARNING are the same except for the N_EXT bit, so just use their
239 values alone, rather than OR-ing them with N_EXT.
241 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
243 * mipsread.c (parse_lines): Deal with negative extended line
246 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
247 global symbol conflicts.
249 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
251 * .gdbinit: Move 'set complaints' to top, so it runs even in
252 case we aren't debugging GDB.
253 * language.c (_initialize_language): Fix type check and range
254 check documentation strings.
255 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
256 language.c can use it. (Though language.c should really not be
257 handling warnings/errors the way it does, FIXME.)
258 * symtab.c (lookup_primitive_type): const lint.
260 Bugfix from Peter Schauer:
261 * source.c (lines_to_list): Make signed, to avoid comparison
262 going unsigned and complaining that -3 is too high for 21 lines.
263 * stack.c (lines_to_list): Ditto.
265 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
267 * Makefile.in (HFILES): Add minimon.h.
268 (VERSION): Roll version number to 4.0.95.
269 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
270 New rules for building distributions. Normal distribution
271 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
272 one level up from here; it calls make-proto-gdb.dir to build a
273 directory `proto-gdb' which is an image of the release. The old
274 `gdb.tar.Z' rule still works too.
275 * config.sub, configure: Roll in latest from ..
277 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
279 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
280 new-target, and new-config chapters; fix minor typos; come closer
281 to usual GNU markup conventions for @file @samp @code @var.
283 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
285 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
286 * mipsread.c (parse_partial_symbols): Enter the name of all
287 structs/unions... into the psymtab so we can access them if the
288 symtab is not read in.
289 * mips-tdep.c: Remove some unneeded #includes.
290 * xconfig/dec3100: Add HAVE_STRSTR.
292 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
294 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
295 * c-exp.y, m2-exp.y: Lint.
296 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
297 * valprint.c (val_print_fields): Check for stub type.
298 * mipsread.c (_initialize_mipsread): Avoid using
299 builtin_type_void at initialize time.
300 (mipscoff_symfile_read): use it now.
302 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
304 Merge multiple-language support, and partial Modula-2 support,
305 from Andrew Beers <beers@cs.buffalo.edu>.
307 * i387-tdep.c: New file, consolidates most 80387 support,
308 and eliminates host dependency on double<->extended conversions.
309 * i386-xdep.c, symm-xdep.c: Remove most 387 support.

401 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
403 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
404 entries are enclosed herein. Not all of these changes
405 have been merged into the master GDB sources -- check the
406 ChangeLog above here for the merge log.
408 Mon Jun 3 17:05:45 EDT 1991
410 m2-exp.y Created. Tested outside of GDB for a few days. Proper
411 operators were added, C specific operators and tokens
412 removed. yylex() revamped to some extent. Still things
413 missing from the grammar, such as sets.
414 Tested for two weeks in GDB v3.5.
416 Tue Jun 11 17:23:48 EDT 1991
418 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
419 so they are built-in. Sort of a hack.
421 Fri Jun 14 12:53:51 EDT 1991
423 m2-exp.y Added range checking for numeric constants. Any numeric
424 constant is assumed to be of builtin type INTEGER unless:
425 (1) it is octal or hexadecimal, in which case it is a
426 CARDINAL; (2) it is too big to fit into an INTEGER, in
427 which case it is a CARDINAL.
428 eval.c Added simple range checking for +, -, and * on integers.
429 Doesn't work very well for *, since 6 * 1,000,000,000 =
430 1,705,032,704, which fails the simple test of result >=
431 first_operand, no matter in what order the operands are.
433 Tue Jun 18 14:11:30 EDT 1991
435 Broke the parser into parts, one containing the C grammar and the other
436 containing code to be shared by all of the grammars.
438 The following files no longer exist:
443 The following files were added:
445 c-exp.y (The C grammar)
446 m2-exp.y (The Modula-2 grammar)
447 parser-code.c (Code that is shared by the above grammar)
451 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
452 now necessary to use the Bison compiler compiler, since it
453 will generate function/variable prefixes other than yy.
455 Tue Jun 18 16:47:49 EDT 1991
457 symtab.[ch] Added the external variable working_lang, than holds the
458 value of the current working language.
459 Added the ennumerated type language_mode, with the values
460 language_auto and language_manual, the former meaning that
461 GDB sets working_lang as needed, and the latter meaning
462 that the value of working_lang is totally under user
464 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
465 REAL, BOOLEAN and CHAR. Also added the type codes
466 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
467 utils.c Added set_language_command and show_language_command to
468 implement the GDB support commands "set language" and
470 expression.h A number of identifiers were added to the type exp_opcode
471 to facilitate Modula-2 builtin functions, integer
472 division, and array indexing.
474 Wed Jun 19 13:25:58 EDT 1991
476 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
477 if the language specified by working_lang requires the use
478 of strict typing of expressions. Eventually, even this
479 will be able to be changed by the user.
480 Added the macro RANGE_CHECK, which evaluates to non-zero
481 if the language specified by working_lang requires the
482 checking of a value against the domain of its type.
483 Eventually, even this will be able to be changed by the
485 language.[ch] Predicates involving types (simple_type, ordered_type,
486 same_type, integral_type, numeric_type, character_type,
487 boolean_type, float_type) are added. These predicates are
488 based on the current value of working_lang, and are handy
491 Wed Jun 19 15:39:34 EDT 1991
493 eval.c Added the function type_array_rank which computes the rank
495 valarith.c Added the funtion value_bool, which when given a integer
496 value.h value (ie. struct value *) as an argument, it returns a
497 boolean value (ie. struct value *) true if that integer
498 is non-zero, and a boolean value false otherwise.
499 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
500 will print out properly.
502 Wed Jun 19 16:36:34 EDT 1991
504 valops.c Added the function value_capitalize, which returns it
505 value.h argument capitalized if its argument is a lowercase
506 letter, or the argument unchanged if its argument is not a
508 valarith.c Added the function range_check_p, which returns non-zero
509 value.h if its value argument is between the integral bounds upper
511 Added the function range_check_enum_p, which makes sure
512 that its value argument is a valid member of the domain of
514 Added the function range_check_range_p, which makes sure
515 its value argument lies between the upper and lower bounds
516 of its type argument, which must be a ranged type.
517 Added the function check_array_index, which range and type
518 checks an index of an array.
519 Added the function value_multi_subscript, which computes
520 array[idx1,idx2...idxN], given a value array and an array
521 of values representing indicies.
522 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
523 unpack_long to work with TYPE_CODE_BOOL and
526 Wed Jun 19 18:04:08 EDT 1991
528 symtab.c Stored pervasive types in a structure and make
529 lookup_pervasive_type() a lookup function that was based
530 on working_lang. If lookup_pervasive_type() returned
531 non-zero, then that value was returned (a fix, since
532 before it simply wouldn't return the pervasive type.)
533 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
534 non-zero if the language specified by working_lang means
535 "conversion" when it says "cast".
536 valops.c Added the function value_real_cast(), which performs a
537 value.h *cast*, not a *conversion*, which is what value_cast()
538 does when it can. In particular,
539 value_cast(<float_type>,4) = 4.0, while
540 value_real_cast(<float_type>,4) = some mess.
541 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
542 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
543 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
544 and MIN on integral types. *NOTE*: These are currently
545 hardcoded to work only if there are 8 bits per storage
547 eval.c Made logical functions call value_bool to return a
548 properly typed boolean value, based on working_lang.
550 Thu Jun 20 11:55:27 EDT 1991
552 valprint.c Types now print out in a Modula-2 fashion. This works for
553 the cases when the type is printed out step-by-step, that
554 is, it doesn't work when the name of a structured type
555 (which includes the keyword "struct", etc.) is simply
557 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
558 since type specifications in C and Modula-2 are very
559 different. The C printing of a type is very recursive,
560 whereas in Modula-2 it is generally very simple. C has
561 type prefixes and suffixes, which have no real analogue in
562 Modula-2. Maybe type_print() should call a language
563 specific type printer. This is also advantageous if we
564 compile GDB to exclude some of the languages. We'll just
565 leave those functions out.
567 Thu Jun 20 16:57:10 EDT 1991
569 dbxread.c When reading the complete symbol table in (via
570 psymtab_to_symtab()), the number and types of function
571 arguments are added to a function type. define_symbol()
572 calls add_param_to_type() to accomplish this.
573 Assumption: when we come across a function definition
574 (N_FUN symbol with an 'f' or 'F' in the name), its
575 arguments will appear before another function definition.
576 When a function is found, a pointer to its type is placed
577 in the global in_function_type. Changes that
578 add_param_to_type() makes are to this global.
579 valprint.c The type of a function now includes (for Modula-2) the
580 types of its parameters.
581 eval.c Type checking and a check for the proper number of
582 arguments is now done for function calls. Not sure of the
583 impact this has on C++ member function yet.
585 Thu Jun 20 19:58:48 EDT 1991
587 valprint.c Rewrote the type printer. Broke it into two language
588 specific parts, adding the functions type_print_m2() and
590 An unfortunate consequence is this: if you debugging a C
591 program in Modula-2 mode (why?), info types does not work
592 well with regular expressions, since the types are printed
593 out in Modula-2 terminology, but stored in C terminology.
594 language.[ch] Added the functions new_type_last(), type_keyword(), and
595 type_sep() to aid in the printing of typedefs.
596 symtab.c Made the printing of typedefs as language independent as
597 possible through calls to new_type_last(), type_keyword(),
600 Fri Jun 21 11:50:26 EDT 1991
602 dbxread.c Check all incoming ennumerated types. If it looks like
603 Modula-2's BOOLEAN type, then change the type_code of the
604 type to TYPE_CODE_BOOL so we can process it as a boolean
606 valprint.c Replaced some of the 0x%x with calls to sprintf and
607 hexformat() in val_print().
608 language.[ch] Added the function hex_to_string(), which converts its
609 integral argument to a hexadecimal number (format is
610 language based) and returns the result as a string.
612 Mon Jun 24 12:25:07 EDT 1991
614 valprint.c Some functions call type_print_1() directly, instead of
615 value.h using type_print(), so they can specify where (column) to
616 print things. Since type_print() takes care of language
617 dependence, that needs to be called first. Added a
618 parameter depth to type_print() (so it is now like
619 type_print_1). Changed type_print to type_print_at, and
620 made type_print a macro that passes a depth argument of
622 symmisc.c Changed all calls to type_print_1 to calls to
624 Makefile.dist Made it possible to build GDB for a specific set of
625 depend languages. Do this by passing a definition for the macro
626 LANGS to make. LANGS should be a string containing a
627 space-separated list of language names (ie. LANGS="c m2").
628 The default is to build all languages. Note that grammar
629 files must follow the naming convention of <lang>-exp.y.
630 gdb.lang This holds the current value of the LANGS macro. It is
631 examined every time make is called, and is updated if
633 eval.c Added #ifdef _LANG_<lang> to these files.
634 expread.c Still need to add them to dbxread.c and coffread.c.
642 Mon Jun 24 16:33:11 EDT 1991
644 language.[ch] Added the functions hexformat_pre() and
645 hex_to_string_pre(), which take a prefix argument to
646 include in the format string. Thus, hexformat_pre("08") will
647 return "0x08x" (if the working language is language_c).
648 Made hexformat() and hex_to_string() calls to the above
649 with "" as the prefix argument.
651 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
652 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
653 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
654 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
655 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
656 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
657 valprint.c, vax-pinsn.c
659 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
660 calls to hexformat() and hex_to_string(). Format strings without
661 the leading "0x" were ignored.
663 depend Updated to take the above into account.
666 Tue Jun 25 15:27:18 EDT 1991
668 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
669 and type_check_t to keep track of the current state of
670 range and type checking.
671 main.c Added the variables range_mode, range_check, type_mode,
672 and type_check to record the current state of range and
673 type checking. Added initialization code to main().
674 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
678 Tue Jun 25 17:57:08 EDT 1991
680 dbxread.c process_one_symbol() updates the variable (enum language)
681 source_lang based on the extension of the filename
682 contained in the N_SO sybmol that started this symtab.
683 When end_symtab() is called, the value of source_lang is
684 put into the language field.
685 stack.c select_frame() sets working_lang (and possibly type_check
686 and range_check) to the language field of the symtab
687 associated with the frame that is selected if working_mode
688 is language_auto. If working_mode is language_manual, a
689 warning is printed and working_lang is not set.
690 language.c Added the function set_type_range(), which sets the value of
691 type_check and range_check (if their modes call for
692 automatic setting) based on the current value of
693 working_lang. A non-zero argument will cause the current
694 settings to be output.
697 Wed Jun 26 14:51:40 EDT 1991
699 eval.c Added range checks on assignment.
700 m2-exp.y Added the grammar for sets to the language. Currently,
701 these do not do anything except print an error message.
703 Wed Jun 26 17:01:04 EDT 1991
705 m2-exp.y Added the ability for parse_number() to parse negative
706 numbers. A global flag is set upon encountering a unary
707 minus. This was done to make, for example, 1 parse as a
708 CARDINAL, and not as an integer, per Wirth's examples in
709 Programming in Modula-2 ed.4.
710 valprint.c Added support for "set radix 2" by then setting
711 output_format to 't'.
712 eval.c Implemented range checking on subrange types. Added calls
713 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
714 Implemented MIN and MAX for ennumerated types. The
715 minimum value of an ennumerated type is defined by Wirth
716 as the first identifier, and the maximum as the last.
717 m2-exp.y Made octal numbers ending with "B" be characters and those
718 ending with "C" be numbers, per Wirth's book. (p. 34)
720 Thu Jun 27 14:11:52 EDT 1991
722 stack.c select_frame() now only sets working_lang, it does not
723 notify the user. If working_mode is language_manual, then
724 a warning is issued once.
725 main.c At the end of each call to execute_command(), working_lang
726 is checked against the local static (enum language)
727 current. If they differ and working_mode is
728 language_auto, the new settings of language, type and
729 range checking are printed out.
730 stack.c Modified frame_info() to include the language of the
731 current frame in the output of "info frame".
732 language.[ch] Added the function language_str() which returns the name
733 of the current language.
735 Fri Jun 28 15:33:14 EDT 1991
737 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
738 the language. INCL and DECL currently cause an error,
739 since sets are not implemented yet. INC and DEC are
740 implemented as PREINCREMENT/PREDECREMENT with one
741 argument, and as ASSIGN_MODIFY with two arguments.
742 eval.c Added type checking to the above cases.
743 value.h Added not_lval_constant to the lval_type ennumerated type.
744 not_lval_constant means that the value is a constant
745 value; that is 3 or 'a' or TRUE, not as in a constant
746 identifier. This is used to help coerce numbers such as 3
747 to either signed or unsigned numbers.
748 valops.c Added the function value_coerce_constants() which coerces
749 constant integers as following: if one is a constant and
750 the other is not, the constant's type is set to the type
751 of the other argument. If both are constants and one is
752 signed, the other is converted to a signed constant.
754 Sat Jun 29 17:26:29 EDT 1991
756 valarith.c Added a better range checker. It now checks range
757 (successfully) on integral operations [+-] (signed and
758 unsigned) for any C sized type. Still does not work well
760 int_in_size() returns an integer that is coerced to fit into
761 specified number of bytes.
763 Mon Jul 1 13:04:14 EDT 1991
765 language.[ch] Added the function binop_result_type(), which returns the
766 builtin (struct type *) type that would be the result of a
767 binop on the two values V1 and V2.
769 Wed Jul 3 19:22:53 EDT 1991
771 source.c Extended source_info() to include the source language in
772 the output from "info source".
774 Fri Jul 5 13:48:52 EDT 1991
776 utils.c Moved the support functions for the GDB set/show commands
777 dealing with language into language.c.
778 language.c Added the function language_info(), which displays info
779 about the current working language, type and range check
780 settings. Called via the GDB command "info language".
781 Added an initialization routine _initialize_language(),
782 that sets defaults for the language, type and range
783 variables and sets up the new GDB commands.
784 main.c Language setup moved to language.c.
787 Mon Jul 8 10:10:22 EDT 1991
789 valarith.c Debugged the range checker for arithmetic. Still does not
790 work for multiplication very well.
792 Mon Jul 8 12:40:37 EDT 1991
794 language.[ch] Added the function value_true() which returns non-zero if
795 its argument represents a boolean true value.
796 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
797 check the truth of an expression.
799 Thu Jul 11 12:51:34 EDT 1991
801 language.[ch] Added the predicate structured_type(), which returns
802 non-zero if the argument is a structured type.
803 Added the predicate pointer_type(), which returns non-zero
804 if the argument is a pointer type.
805 eval.c Added the ability to do addition and substraction on
806 pointers and integers. This case simply bypasses the
809 Thu Jul 11 14:41:42 EDT 1991
812 Added the symbol N_DEFD (0x4a) which is a definition
813 module dependency that is used by the GNU Modula-2
814 compiler and the linker. It is not important to GDB,
815 except that [dbx|coff|mips]read.c should ignore these
818 Fri Jul 12 16:07:00 EDT 1991
820 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
821 0 in val_print(). Also added statements to the else part
822 to coerce type (argument to val_print) to a pointer type
823 if it is an "array of unspecified length".
824 valops.c Added the function value_m2_string(), which returns a
825 (value) value which is a constant string, whose type is
826 (ARRAY [0..n] OF CHAR). The length field of the type
827 structure is set to zero, so it will be interpreted as an
828 "array of unspecified length".
829 stack.c Moved the language/frame mismatch check to
830 main.c:execute_command().
831 main.c The working language is recorded each time
832 execute_command() is executed. If working lang has
833 changed during its execution, then the new
834 language/type/range info is printed out for the user. If
835 the working language does not match the language of the
836 frame, a warning is issued.
838 Sat Jul 13 16:16:39 EDT 1991
840 eval.c Moved all the type-checking stuff for operators to
841 language.[ch] language.c. This is so we can keep language-specific
842 stuff (like for what type operators are defined) in
844 language.[ch] Added the function binop_type_check(), which checks to see
845 if its two (value) arguments are type-compatible with its
846 opcode argument. The opcode should represent an operation
847 involving an operator. Also added the macro function
848 unop_type_check, which calls binop_type_check with a
849 NULL second argument.
850 expprint.c Added Modula-2 operators to the op_print_tab, so info
851 expression.h break works correctly. Also added "op_string", which
852 returns the string corresponding to the (enum exp_opcode)
853 opcode that is its argument.
856 Sat Jul 13 18:26:18 EDT 1991
858 coffread.c Added code to record the type of function arguments with
859 each paricular function. Code is very similar to that
861 dbxread.c Moved add_param_to_type() to symtab.c
862 symtab.[ch] Added function add_param_to_type() from dbxread.c
864 *** NOTE: The above additions have not been tested.
866 Mon Jul 15 12:50:47 EDT 1991
868 langauge.[ch] Added the functions type_error and range_error, which work
869 like error() except if the type/range mode is set to
870 *_mode_warn, then they do not do a return_to_top_level(),
871 but merely print a warning.
872 Also changed [set|show]_[type|range]_command() to support
873 the new "warn" feature.
875 Thu Jul 18 17:50:54 EDT 1991
877 mipsread.c Added code to record the type of function arguments with
878 each particular function. Code is very similar to that
881 *** NOTE: The above additions have not been tested.
883 Fri Jul 19 11:19:10 EDT 1991
885 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
886 UMIN_OF_SIZE, which when given a size of a numeric type,
887 return the maximum and minimum value it can hold. UMAX...
888 and UMIN... return the result for unsigned types.
889 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
890 struct types. They call above macros.
891 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
892 avoid a name conlict with the above.
893 c-exp.y Added range checking on numeric constants in
894 parse_number() for completeness.
895 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
896 return 0 if working_lang is not language_c.
898 Thu Aug 8 14:17:22 EDT 1991
902 breakpoint.c Documentation strings of some commands changed to
903 eliminate the references to the C language where
906 Tue Aug 13 15:48:03 EDT 1991
908 m2-exp.y Added qualified identifiers to the grammar. The semantics
909 are slightly different from those of the GDB operator ::
911 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
912 type_exp, where type_exp is any valid type expression.
914 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
915 printcmd.c Modified ptype_command() so it actually parses the input
916 (necessary for type expressions with scope qualifiers).
917 Added the function ptype_eval() which expects an
918 expression composed of one OP_TYPE element.
919 *.[ch] Replaced all occurences of parse_c_expression with
921 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
923 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
925 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
927 Small fixes from Peter Schauer:
929 * infrun.c (child_attach): Lint.
930 * solib.c (find_solib): Handle shared libs version 2.
932 Small fixes from David Wood:
934 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
938 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
939 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
941 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
942 chars_per_line is at maximum (user typed `set width 0'). Fix
943 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
945 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
947 * coredep.c: include ptrace.h where necessary.
948 * mipsread.c(parse_lines): fix unsigned char problem that was
949 messing up line numbers on SGI's and possibly other MIPS based
951 * infrun.c (child_create_inferior): use better test to check
952 return val from setpgrp().
953 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
954 for sgi/irix support.
956 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
958 * mipsread.c (parse_symbol): Put non-static procedures
961 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
963 Patch together `text_start' and `text_end' for 29K port.
965 * exec.c (exec_command): If NEED_TEXT_START_END, define the
966 variables and set them based on the exec file.
967 * am29k-tdep.c: declare text_start.
968 * valops.c (call_function_by_hand): declare text_end.
970 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
971 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
972 because machines that do this will also have to know to
973 set NEED_TEXT_START_END. Besides, it was a redundant way to
975 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
976 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
979 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
981 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
983 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
984 Pass MUNCH_DEFINE to munch whenever we run it.
985 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
986 format string; use 0x%x instead.
987 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
988 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
989 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
990 * inflow.c: Handle `short' process group IDs.
991 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
992 and check for ptrace errors.
993 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
994 (coff_symfile_init): Initialize text_bfd_scnum.
995 (read_coff_symtab): Use it to find the text [and absolute?] sections.
996 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
997 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
998 Merge target arm case with other "easy" cases. Add target
999 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1000 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1002 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1003 * munch: Cope with RT/PC putting fns in data segment.
1004 Restore ability to override `nm' by specifying MUNCH_NM.
1005 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1006 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1007 and remote-adapt. Remove encapsulated coff #define's (the
1008 support should go in BFD, and gdb shouldn't know or care).
1009 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1010 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1011 * tm-29k.h: Update BADMAG (though it should go away).
1012 Allow the register definitions to be overridden in another
1013 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1014 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1015 DUMMY_SAVE_GR96, for handling kernel calling conventions
1016 that use GR64+ rather than GR96+.
1017 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1018 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1019 overrides various things.
1021 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1022 child_attach does, making a clean stop in the newly attached
1024 * remote-eb.c: Lint.
1026 * coffread.c: Make coffread independent of any particular
1027 variant of COFF. Avoid #include-ing any particular one except
1028 internalcoff.h. BFD now passes key values for symbol reading
1029 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1030 and the symbol masks and shifts); use them.
1031 Remove obsolete end_of_text_addr.
1033 * exec.c: Remove unused include files.
1035 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1037 * Makefile.in (documentation targets): Pass $(M4).
1038 Bugfix from eggert@twinsun.com (Paul Eggert).
1040 * stack.c (down_silently_command): Check for stack existence.
1042 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1044 * Makefile.in (VERSION): Update to 4.0.3.
1046 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1048 * core.c (core_file_command): Print frame at coredump with
1049 its level number, by calling print_stack_frame.
1050 * frame.h: Add selected_frame_level, print_stack_frame.
1051 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1052 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1053 Change print_sel_frame and print_selected_frame callers to
1056 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1057 * symfile.c (free_named_symtabs): Ditto.
1058 * main.c (main): wrap_here needs an arg.
1059 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1060 (solib_add): Avoid noise.
1061 (solib_create_inferior_hook): Lint.
1062 (sharedlibrary_command): Move dont_repeat to here.
1063 * utils.c (error): Call wrap_here to force buffered output.
1065 Small patches from Peter Schauer:
1067 * coffread.c (start_symtab): Free any existing line_vector before
1069 (read_coff_symtab): Ditto for type_vector.
1071 * source.c (lines_to_list): New variable, replacing function.
1072 (all uses): Use as variable.
1073 (_initialize_source): Add 'set listsize' and 'show listsize'.
1074 * utils.c (lines_to_list): Remove function.
1075 * stack.c (print_frame_info): Use as variable.
1076 * defs.h (lines_to_list): Remove declaration.
1078 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1080 * breakpoint.c (insert_breakpoints): Restore warning about
1081 the program might be running in another process, but only for
1082 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1083 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1085 * utils.c (error): if error_pre_print is set, print the string
1087 * main.c (main, print_gnu_advertisement, print_gdb_version):
1088 Reformat legalese so it always prints, but acts as an "I'm here"
1089 message while symbols are being read. If any errors occur,
1090 print a few newlines to set off the message and start it at the
1091 left margin. Remove mention of "help" command, and don't yak
1092 about symbol reading.
1093 (catch_errors): Error string is now printed first in case of
1095 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1096 suggest the "help" command.
1098 * Makefile.in (VERSION): Set to 4.0.2.
1100 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1102 * .gdbinit: Remove useless "rr" command. Set complaints
1103 to 1 for people debugging gdb.
1105 * breakpoint.c, remote-vx.c: Reword strings printed by
1106 catch_errors callers.
1108 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1110 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1111 (Fix from kenc@viewlogic.com.)
1113 Fix some infrastructure to be able to cope with host and target
1114 machines with different sized basic types (ints, ptrs, etc).
1115 (Idea from pierre@la.tce.com (Pierre Willard).)
1117 * values.c (value_from_longest): Rename from value_from_long.
1118 Handle pointer types as well as integers, so that targets with
1119 different pointer sizes from the host can be accomodated.
1120 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1121 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1122 uses of value_from_long to value_from_longest.
1123 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1124 the correct pointer type to value_from_long{est}.
1126 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1128 * remote-vx.c: Remove obsolete code for calling functions via
1129 vxworks kludge interface (it referenced value_from_long).
1131 * valops.c (value_string): Find malloc with lookup_misc_func, not
1134 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1136 Make writing to files work properly. (Fixes to BFD are also needed.)
1138 * core.c (core_open): Open file ourselves, read or r/w, depending on
1139 write_files. Use bfd_fdopenr.
1140 * gdbcore.h (write_files): New variable.
1141 * exec.c (write_files): Define variable, add set&show for it.
1142 (exec_file_command): Use write_files to open for read or r/write.
1144 Make shared library reading happen automatically. These changes
1145 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1147 * inferior.h (stop_soon_quietly): Add to exported variables.
1148 * infrun.c (child_create_inferior): call solib hook, if defined.
1149 (child_attach): call solib hook, if defined.
1150 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1151 (find_solib): Use lookup_misc_func rather than hand-rolled.
1152 (symbol_add_stub): New stub for catch_errors.
1153 (solib_add): Avoid output if !from_tty. Catch errors rather
1154 than just calling symbol_file_add and bombing.
1155 (solib_create_inferior_hook): Interface with the target process
1156 to let it read and alloc shared libs, then figure out what it did.
1158 * core.c (validate_files): Fix typo, soften warning.
1159 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1161 * utils.c (fputs_demangled): Avoid duplicate printing if
1162 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1164 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1165 (Fix from pierre@la.tce.com (Pierre Willard).)
1167 * main.c (catch_errors): Change argument to a char * from an int,
1168 since a char * can point to a struct full of glop, but an int
1169 is not guaranteed to be able to hold a pointer.
1170 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1171 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1172 * core.c (core_open, solib_add_stub): Adapt.
1173 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1175 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1177 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1178 by adding .NOEXPORT target.
1180 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1184 * Makefile.in (VERSION): Roll to 4.0.
1185 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1187 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1189 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1192 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1195 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1197 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1198 reflect above name change
1200 * WHATS.NEW: correct pointer to refcard.
1202 * doc/gdb.texinfo: update New Features, Installing
1204 * doc/gdbint.texinfo: add short description of configure +template
1206 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1208 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1210 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1212 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1213 tar file, add dependencies for referenced doc files.
1215 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1217 * coffread.c, symfile.c, stack.c: saberized.
1219 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1221 * doc/refcard.tex: permuted Essential Commands sec
1223 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1225 set/show symbol-reloading
1226 default set complaints 0
1228 RET-repeat disabled after prompted long displays
1229 processID (attach) interpretation of 2nd GDB cmdline arg
1231 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1233 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1234 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1235 breakpoint.c, main.c: lint.
1237 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1239 Install new configuration scheme for GDB and friends.
1241 * config.sub: Translate ordinary names to three-part names.
1242 * configure: Use three-part names internally.
1243 * configure.in: Translate three-part names to filenames.
1245 * README, WHATS.NEW: Update for gdb-4.0.
1246 * Makefile.in: Roll VERSION to 3.99.
1248 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1250 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1251 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1252 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1253 to single structures rather than arrays; when passing
1254 their address, use &. This avoids trouble with bdead compilers.
1255 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1256 instead. This avoids portability headaches.
1257 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1259 * source.c (open_source_file): Avoid ANSI const bdeath by
1260 skipping declaration and then casting result value.
1261 * tm-hp300bsd.h: Clarify comment.
1262 * utils.c (strstr): Result is const char *; ANSI bdeath.
1263 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1264 since system include file defines it differently from "defs.h",
1265 though the two are equivalent for our purposes.
1266 * tconfig/hp300bsd: Add m68k-tdep.o.
1268 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1270 * tconfig/sun*4: Remove warnings about system assembler.
1272 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1274 * mcheck.c: Avoid warning about undeclared abort fn.
1275 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1276 it causes recursive calls to error() when used in cleanups.
1277 To do so requires that we make it a function, so we do.
1278 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1279 * utils.c (do_cleanups): Remove the current cleanup from the
1280 chain *before* calling it, in case error() is called from it.
1281 The result won't be pretty, but won't be an infinite loop either.
1283 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1285 * dbxread.c (read_struct_type): Grok anon structs for C++.
1286 (vb_name, vptr_name): Null terminate these strings.
1288 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1290 Minor bug fixes from BSD Net2 gdb:
1292 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1293 returns 0, there is no previous frame.
1294 * breakpoint.c (commands_command): If !from_tty, don't call
1295 input_from_terminal_p().
1296 * dbxread.c (record_misc_function): Speed up slightly.
1297 (compare_psymbols): Ditto.
1298 * infcmd.c (do_registers_info): Take a second argument to
1299 determine whether to print float registers. "info registers"
1300 does not do so anymore. "info all-registers" does, now.
1301 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1303 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1304 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1308 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1309 executing_breakpoint_commands if we are interrupted by error.
1310 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1311 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1312 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1313 catch_errors() so we can setup the frame regardless of whether
1314 the shared libs work.
1315 * ieee-float.c (double_to_ieee_extended): Get exponent from
1316 right place in little-endian systems. From John Carey.
1318 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1320 * main.c: Remove unused terminating_signals and catch_termination().
1321 (long_options): Terminate with a zero element.
1322 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1323 (gdb_readline): Make call-compatible with readline.
1324 (init_signals): Improve comments re vfork vs. signal.
1326 * utils.c (prompt_for_continue): Use new gdb_readline().
1327 If we prompt for continuation, we don't let CR repeat the previous
1328 command, once we get back to a prompt. It's too easy to keep
1329 hitting CR, expecting "--more--" prompts, and have some long
1330 command start repeating on you.
1332 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1334 * blockframe.c (frameless_look_for_prologue): Speed up by
1335 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1336 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1337 Define two variants, one faster.
1338 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1339 and return zero, rather than giving an error.
1340 (setup_arbitrary_frame): Initialize the PC in the new frame.
1341 (skip_prologue): Add a second arg saying whether we're just
1342 checking for a frameless function or not.
1344 * core.c (core_open, core_close, core_xfer_memory): Move
1345 section table pointers and bfd* into the target_ops.
1346 (core_open): Allow errors in shared lib reading, etc.
1347 (core_files_info): Describe shared library sections.
1349 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1350 exec_files_info, set_section_command): Move section table
1351 pointers and bfd* into the target_ops.
1352 (add_to_section_table): Add BFD to section table.
1354 * target.c (target_xfer_memory, target_info): Pass target to
1355 xfer_memory and target_info functions.
1358 * gdbcore.h: Move struct section_table.
1359 * target.h: New home of struct section_table.
1361 * solib.c (solib_add): New argument is the target_ops whose
1362 section list is to be added to, if any. Reallocate the
1363 sections in that target to add any that come from shared libs.
1364 (throughout) so_sections renamed to sections.
1365 (solib_xfer_memory): Deleted.
1366 * tm-sunos.h (SOLIB_ADD): Add target argument.
1367 (SOLIB_XFER_MEMORY): Delete.
1369 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1370 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1371 from target_ops. It's the same on all targets. Add two section
1372 pointers to target_ops.
1374 * stack.c (find_relative_frame): Dump ancient algorithm for
1375 "down", just use handy "next" pointers.
1376 (frame_command): Don't error if there is no stack; let user
1379 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1380 modifies static state in the parent process; new_tty itself
1381 runs in the child and modifies the child's file descriptors
1382 to match the saved static state.
1383 * infrun.c (child_create_inferior): Call new_tty_prefork,
1386 * infptrace.c (child_xfer_memory): Add ignored target arg.
1387 * remote-eb.c (eb_xfer_inferior_memory): ''
1388 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1389 * remote-vx.c (vx_xfer_memory): ''
1390 * remote.c (remote_xfer_memory): ''. Rename from
1391 remote_xfer_inferior_memory.
1393 * main.c (main): Only try to attach "corefile" argument if
1394 it starts with a digit.
1396 * symfile.c (symbol_reloading): New "set/show" variable.
1397 (symbol_file_add): Shorten message about symbol reading.
1398 (add_symbol_file_command): Merge with add_syms_addr_command,
1399 since this should work on all targets now.
1400 (stop_whining): Default to zero, to shut up complaints
1401 about bad symbol tables on many systems.
1402 (free_named_symtabs): Just exit unless symbol_reloading.
1404 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1405 and add comment explaining shared library screw.
1407 * source.c: #if defined => #ifdef.
1409 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1411 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1413 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1415 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1416 (doc/Makefile knows how to make one for local config)
1418 * Makefile.in: use doc/Makefile for doc targets
1420 * doc/Makefile: GDB documentation now has its own Makefile
1421 doc/refcard.tex: renamed from "gdbrc.tex"
1422 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1423 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1426 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1428 * values.c (baseclass_addr): When reading target memory, use the
1429 length of the basetype, not the upper type. We've only malloc'd
1430 enough space for the basetype, leading to errors in free().
1432 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1433 ends up as a function specially, since we know the actual type of
1434 the pointed-to address. This (somewhat) fixes display of
1435 expressions that include misc_function_vector names. Try `cond 1
1436 !strcmp("a","b")' then `i b'.
1438 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1439 The child can be proceeded from inside wait_for_inferior in
1440 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1441 getting skipped in that case.
1443 * expprint.c (print_subexp): Use filtered output, since the
1444 subroutines we call use it, otherwise the output is horribly
1445 mangled, since output of wrappable stuff comes out late.
1447 * Makefile.in: Bump VERSION to 3.98.1
1449 * infrun.c (child_create_process): Use execlp to find the
1450 shell to exec our target program. This requires some fiddling
1451 with `environ' since there is no execlpe().
1453 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1455 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1456 Minor rearrangement of refcard permits two new make targets--
1457 gdbrc.dvi DVI output for refcard, using CM fonts
1458 gdbrc.ps PostScript refcard, using PS fonts
1460 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1464 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1465 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1467 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1469 * doc/gdb.texinfo: last changes for release.
1470 Minor typo and formatting fixes; incorporated most fixes remaining from
1471 filed mail commenting on earlier drafts.
1473 Added warnings: pipes don't work in run command;
1474 conditions are converse of assertions;
1475 step over fn without debug info goes to next fn;
1476 vars may have "wrong" values near fn entrance, exit
1478 Added example from Kingston on printing repeated nonadjacent values
1480 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1481 shell mode for signals
1483 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1484 doesn't sound so much like its parent "Stopping and Continuing"; also
1485 moved entries on continue to top of section, so they don't get lost.
1487 Improved installation directions in appendix, added manual formatting
1490 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1492 * configure.in: Remove xm.h and tm.h even if we aren't linking
1493 new ones, so "./configure sun4; ./configure none" does the right
1494 thing. Assume that alldeps.mak and depend are already built in
1495 srcdir, and avoid running "make" (particularly "make depend",
1496 which involves "gcc") from inside configure. Build Makefile
1497 directly rather than building Makefile.conf first.
1498 * configure: Regenerate with above changes.
1499 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1500 to 3.98. Revise gdb.tar.Z procedure to produce a file
1501 called gdb-$(VERSION).tar.Z but which unpacks into a
1502 directory called "gdb". Move non-source files out of
1503 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1504 (depend): Don't try to do "gcc expread.y".
1505 (expread.o): Update dependencies by hand.
1507 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1510 Fixed a variety of small typos that prevented info from formatting
1511 cleanly; altered too-long heading for GPL Appendix, as discussed
1512 w/RMS; Changed date on cover to July 91.
1514 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1517 (1) Applied some fixes due to comments from Larry Breed (easier ones
1518 through chapsec 5.2)
1519 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1520 it's broken in latest texinfo
1521 (3) Introduced *some* use of [] for optional arguments, where
1522 explanation is not simpler by listing cmd w arg and cmd w/out arg
1523 separately. Still not using @deffn.
1524 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1525 couple of headings are too long. Need patches to texinfo or revision
1528 * Partial update to README (which still needs work for this
1529 release!): (1) use of configure corrected for new script,
1530 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1532 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1534 * symtab.c (lookup_symbol): Don't complain right off about
1535 no debug symbols; use the misc function vector first.
1536 (list_symbols): Use misc function vector to find symbols
1537 that don't have debug info, and print them.
1538 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1539 PC range doesn't match symtab PC range, as it does on the
1540 MIPS because our symtab reading isn't perfect.
1542 * dbxread.c (dbx_symfile_read): Make warning about
1543 "no debug symbols" slightly nicer.
1545 * source.c (select_source_symtab): If "main" symbol exists,
1546 but decode_line_spec can't find line info, don't just return
1547 a zero; try other source symtabs or give an error.
1549 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1550 their low addresses first, then rip through fixing high addrs.
1552 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1553 <runene@ifi.uio.no>.
1554 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1556 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1558 * Minor, mostly mechanical, cleanup of doc subdir for clean
1559 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1560 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1562 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
1564 Mostly MIPS and general symbol-reading fixups.
1566 * doc/gdbint.texinfo: Add documentation on symbol-reading
1569 * mipsread.c: Remove kludges around #include "ecoff.h".
1570 Remove redefinitions of a_magic, etc, no longer used.
1571 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
1572 Fix global overview comments to match symfile.c protocol.
1573 (mipscoff_new_init): Eliminate cur_hdr if we have one.
1574 (mipscoff_symfile_read): Eliminate unused code. Avoid
1575 sorting all the symtabs, when all we have read here is psymtabs.
1576 The symtabs are sorted as they are created anyway. Tell
1577 condense_misc_bunches whether we're mainline.
1578 (psymtab_to_symtab_1): Pass filename when recursing, to make
1579 stack trace more informative.
1580 (parse_partial_symbols): Assume cur_hdr as argument.
1581 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
1582 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
1583 the TYPE_NAME of char *, since that's done in symfile.c.
1584 (free_numargs, parse_symbol, add_symbol, add_block,
1585 shrink_linetable): Declare these fns void.
1586 (upgrade_type): Convert tree of if's to switch. Clean up
1587 bogus "off == 0" handling with a complaint. Avoid setting
1588 field bitpos and bitsize of array with lower and upper bounds.
1589 Check specified bitsize of elements against their actual type's
1590 bitsize, and complain if different. Complain about unknown
1592 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
1593 (psymtab_to_symtab_1): Print names of subsidiary files that
1594 are being read in. FIXME, we read far too many files. This code
1595 is not the problem, the problem is in parse_fdr where the psymtabs
1597 (cross_ref): Result should indicate that we used one aux entry
1598 normally, or two if we encountered a "next" entry. This used
1599 to leave the caller pointing at the wrong aux entry.
1600 (add_symbol): If overflowed cur_block, reallocate it larger,
1601 chase all pointers to it, and complain(), rather than clobber memory.
1602 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
1603 (new_field): Only allocate one field initially, not two.
1604 Pull ++ out of macro argument. Simplify.
1605 (_initialize_mipsread): Avoid initialization of importd
1606 global_psymbols and static_psymbols.
1608 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
1609 to properly set pst->symtab; avoid searching for it.
1610 (symfile_fns): Improve comments, add a FIXME.
1611 * dbxread.c: Update comments to reflect symfile protocol.
1612 (read_ofile_symtab, end_symtab): Return the symtab.
1613 (psymtab_to_symtab_1): Set pst->symtab.
1615 * coffread.c (coff_symfile_read): tell condense_misc_bunches
1616 whether we're mainline.
1618 * symfile.h (sym_fns): Remove unused sym_discard member.
1619 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
1621 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
1622 the environment variable is not.
1623 * infcmd.c (finish_command): Use filtered printfs.
1624 * cplus-dem.c: Add struct tags to a few unnamed structs.
1625 * valops.c (value_coerce_array): Improve comments.
1626 * valprint.c (type_print_varspec_suffix): Print array size only
1627 if greater than zero.
1628 * m88k-tdep.c: Shift some lines left by one space, that had
1629 apparently been trashed at some point.
1630 * TODO: More things to do, a few got done.
1632 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1634 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
1635 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
1637 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
1638 * expread.y, findvar.c, symmisc.c: Ditto.
1639 * printcmd.c (address_info): Update printed forms of LOC_
1640 symbols. Elim LOC_EXTERNAL.
1641 (print_frame_args): Keep track of param stack offsets before
1642 re-looking up to find the local register param is kept in.
1644 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
1645 Further integration of mipsread into gdb. Eliminate unused
1646 routines, duplicate declarations. Handle static symbols in
1647 psymtabs as well as external symbols. When reading symtabs,
1648 insert symbols into the correct block (global, static, or a local
1650 (read_mips_symtab, parse_partial_symbols): Don't pass useless
1652 (mipscoff_symfile_read): Don't call select_source_symtab.
1653 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
1654 rather than SYMBOL_VALUE.
1655 (parse_external): Comment clobbering of top_stack.
1656 (parse_partial_symbols): Update comments. Allocate and parse
1657 static symbols as well as external symbols. FIXME, enum values
1658 are not handled in this pass, but should be. Inline new_psymbol.
1659 Use SYMBOL_VALUE_ADDRESS.
1660 (psymtab_to_symtab_1): Read symbols into global static block
1661 by default (until enter some function's local block context).
1662 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
1663 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
1665 * source.c (select_source_symtab): Select a source symtab
1666 from either the symtabs or, failing that, the psymtabs.
1667 (list_command): Update error message.
1668 (forward_search_command, reverse_search_command): Use getc, not
1669 fgetc, for speed. FIXME, add comment about buffers that die if
1670 overrun by long line.
1672 * values.c (unpack_field_as_long, modify_field): Avoid shifting
1673 by an entire word, which is not portable, if we have a 32-bit
1674 field. (Code in dbxread.c already turns such bitfields, if
1675 aligned, into ordinary ints, but fixing this will help for other
1676 symbol formats and for future changes.)
1677 * core.c (core_open): Handle ANSI const brain death.
1678 * utils.c (vprintf): Fix varargs typo.
1680 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1682 * findvar.c (find_var_value): Handle &function better.
1683 * TODO: Document work needed on &fn and &array.
1684 * printcmd.c (print_address_symbolic): New arg is the prefix
1685 to print if a name is printed.
1686 (print_address_demangle): Honor "set print address" now.
1687 Use new arg above to improve spacing of output.
1688 * valprint.c (val_print): When printing function pointers,
1689 print symbolic form too.
1690 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
1692 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1694 * core.c (memory_error): Reword error msg to mislead less.
1696 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
1698 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
1699 parse_partial_symbols): Use newer BFD internals (external_filehdr
1700 and external_aouthdr), byte-swap the fields that we care about
1701 before using them, and make the file header data local to
1702 read_the_mips_symtab rather than global.
1704 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
1706 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
1707 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
1709 * main.c (command_line_input): Flush stdout and stderr
1710 before every call to readline. This reportedly fixes a bug
1711 that comes up in Sys V running emacs-gdb and/or xxgdb,
1712 when stdin/out are pipes or sockets.
1714 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1716 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
1717 Avoid declaring Makefile dependencies, because GNU Make stupidly
1718 tries to update it if we do.
1720 * coffread.c: Revise for minor changes to bfd internal coff
1723 * configure: If -template= is given a relative path, make it
1724 absolute before recurring in subdirectories.
1726 * configure, configure.in, Makefile.in: Install "configure" script
1727 as replacement for config.gdb.
1728 * config.gdb, Makefile.dist, Makefile.sdir: Remove
1729 * README: Update for configure, mostly. FIXME.
1731 * Add dec3100 as equivalent to littlemips. Indicate in all host &
1732 target config files that they are for the host. When the lines
1733 get copied into the Makefile, this makes it more obvious what's
1736 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1738 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
1739 tabs, which end up in the disassembler output inadvertently.
1741 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1743 Make it compile cleanly in an ANSI GCC2 environment.
1745 * blockframe.c: <stdio.h>
1746 * cplus-dem.c: free takes a void *, ifdef __STDC__
1747 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
1749 * defs.h (alloca): Avoid doing anything if alloca already def'd.
1750 * stddef.h, stdlib.h: Remove these files.
1751 * symtab.c: Avoid declaring qsort, close.
1752 * symfile.c: Avoid declaring close.
1753 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
1754 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
1756 Assorted other changes.
1757 * dbxread.c: include "libaout.h", not "liba.out.h".
1758 * printcmd.c (print_frame_args): Set recurse properly for
1759 indentation of struct and array parameters.
1760 * valops.c (value_cast): Allow cast to void.
1761 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
1762 single_step() in a target-independent fashion.
1763 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
1764 set up to be ready to continue. This makes us target independent.
1765 * infptrace.c (child_resume): Remove call to single_step; now
1766 can single step a SPARC target of any kind.
1768 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1770 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
1771 docn into separate sections---basically chapters, plus two loose
1772 pieces that can be configured to go in different places. This
1773 allows GNU m4 to preprocess the manual without coredumping.
1775 * Makefile.dist: tell TeX where to find texinfo.
1777 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1779 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
1780 the new target "rdl-apps.texinfo" which captures the Makefile
1781 variable that records where to find the Readline libraries.
1783 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
1785 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
1786 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
1787 * defs.h (const, volatile): Only define if not already defined.
1788 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
1790 * README: Update for release 3.95.
1791 * config.gdb: Don't create readline dir in subdir builds.
1792 * main.c: Include with "..." form for non-system include files,
1793 so "gcc -MM" for "make depend" works.
1794 Include readline files with "...h" rather than <readline/...h>.
1795 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
1797 * coffread.c: Undo minor damage done by Rich Pixley. Use
1798 different internal and external representations of COFF
1799 data structures. Use new BFD routines for swapping them in and
1801 * symfile.c (free_named_symtabs): Avoid freeing file names that
1802 are null or empty. Old i960 tools seem to produce files that
1803 claim to have empty names, causing each successive file read
1804 to blow away the previous one.
1805 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
1806 Move deferred_stores to top of file, but don't separate its
1807 #define's from its variable. Add commentary.
1808 * Makefile.dist: Fix Rich damage; undo "configure" changes in
1809 favor of keeping the (working) config.gdb. Move readline
1812 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
1814 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
1816 * infptrace.c (fetch_registers): no result, since now void.
1817 * tconfig/news: target depends on m68k-tdep too.
1819 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1821 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
1824 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
1825 applied various small fixes due to or inspired by RMS comments
1827 * doc/gdb.texinfo: finished using all RMS comments, save those for
1828 appendices on readline and cmd history (which are in other source
1831 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1833 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
1834 chapter 9; (2) documented 'break' command's menu mode for
1835 overloaded names, in response to hgs problem report C++ p-31
1837 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1839 * doc/gdb.texinfo: (1) better introductory example; (2) more
1840 consistent use of @code, @samp, @file, @kbd throughout; small
1841 cleanups to first three nodes; (3) new "Contributors" node;
1842 (4) Appendix, Renamed Commands; (5) divert specialized startup
1843 instructions to "Targets" chapter for generic manuals, while
1844 leaving them up front for manuals specific to specialized
1845 environments; (6) apply fixes from RMS comments through chapter 4.
1847 * pretex.m4: modify explanatory text slightly (and redefine
1848 "regexp") to keep GNU m4 from complaining. (It still crashes
1849 later, but one step at a time...)
1851 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
1853 * readline/readline.c (update_line): Avoid dereferencing a pointer
1854 before comparing it to its bounds. Saber caught this.
1855 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
1856 and only set PC if tgetstr returned non-null. Saber caught this.
1858 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1860 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
1861 stuff for config manual) here where it counts; updated
1862 to use new subdir structure (gdb/doc/).
1864 * Makefile: generated from above via
1868 * gdbint.texinfo: added instructions on generating gdb.info* files
1869 locally for release. These are ordinary info
1870 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
1871 Makefile)---but due to use of texinfo 2, can't count on makeinfo
1872 to generate these, so we distribute them already formatted.
1874 * gdb.texinfo: included full Info node and menu crud (as generated
1875 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
1877 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
1878 put in comments-for-future gdb.info target (one day makeinfo will
1881 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1883 * gdb.texinfo: Updated to include new or old undocumented
1884 commands, at least the following (perhaps some others I forgot to
1885 record): info f, info float, info path, info program, info s, info
1886 set, info source, info terminal, info types, info user, set/show
1888 Also covered all recent GDB command renames for v4.
1890 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1892 * mipsread.c: Rather than keeping count of how many symtabs
1893 and psymtabs we have, for sorting purposes, count them when
1894 we need to sort. This fixes bug in rereading of symbol tables.
1896 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1898 * infcmd.c: renamed "info path" to "show paths"
1899 * gdbrc.tex: documented above.
1901 Wed May 8 04:51:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1903 * remote.c: Fix comments.
1904 * utils.c (error): Force out any pending wrap output.
1906 Sat May 4 11:11:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1908 * Makefile.dist: Roll VERSION to 3.95.
1909 Fix up "saber_gdb" to work again.
1910 * saber.suppress: Update.
1912 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
1913 symtab.h, target.c, target.h: Lint.
1914 * core.c: setup and select frame after reading shared libs,
1915 else reading shared libs will clobber them. Lint.
1916 * utils.c (error): Force out any buffered wrap text.
1918 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1920 * remote.c: Remove decls of memory_insert_breakpoint
1921 and memory_remove_breakpoint, no longer used. (Suggestion of
1924 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
1925 to make it easier to interface to "configure"'d libraries.
1927 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
1929 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
1930 aliases for set/show print.
1932 Thu May 2 11:22:02 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
1934 * coffread.c (coff_sym_fns) [TDESC]: Make the type be m88kbcs.
1936 * m88k-tdep.c (IEEE_isNAN): New function.
1938 * infrun.c, m88k-tdep.c, m88k-xdep.c: Change

1945 * m88k-xdep.c: #if 0 out push_breakpoint.
1947 * tm-88k.h: Define GET_SAVED_REGISTER.
1949 * tm-88k.h: Define DGUX.
1951 * m88k-opcode.h (UEXT, SEXT, MAKE): Put parentheses around arguments.
1953 * m88k-pinsn.c (sprint_address): Declare at top of file.
1955 * m88k-xdep.c: #if 0 out core_file_command.
1957 * values.c ({unpack_,value_as_}pointer): Just call
1958 {unpack_,value_as_}long (for now anyway).
1960 * m88k-tdep.c (get_saved_register): Make get_reg a dc_word_t (*)().
1961 (psr_register): Change return type to dc_word_t.
1963 * m88k-tdep.c (tdesc_read_function): Comment out call to ptrace.
1965 * m88k-tdep.c (get_saved_register): Add lvalp parameter.
1967 * gdbcore.h (write_memory): Don't prototype it.
1969 * tm-88k.h, m88k-tdep.c: Make stack_error, stack_jmp global.
1970 m88k-xdep.c: Don't mention stack_error.
1972 * {x,t}config/m88k ({X,T}DEPFILES): Add missing files.
1974 * mtrace.c: Don't typedef things like size_t, just #define them.
1976 * coffread.c [TDESC]: #if 0 out references to coffsyn.
1978 * symtab.h (struct symtab): Include EXTRA_SYMTAB_INFO.
1979 tm-88k.h: Define EXTRA_SYMTAB_INFO.
1981 * coffread.c [TDESC]: Include "tdesc.h" and make tdesc_handle
1982 dc_dcontext_t not int.
1984 * coffread.c [TDESC]: Use system include files not <intel-coff.h>.
1986 * coffread.c [TDESC]: Move setting of debug_info from
1987 coff_symfile_read to find_linenos and make it work with BFD.

2457 Rename {copying,warranty}_info to show_{copying,warranty}.
2459 * symfile.c: Rename add_syms_command to add_symbol_file_command.
2460 (_initialize_symfile, add_syms_addr_command):
2461 Rename add-syms to add-symbol-file.
2463 Thu Apr 18 18:08:30 1991 John Gilmore (gnu at cygint.cygnus.com)
2465 * symfile.h (free_named_symtabs): Rename from free_named_symtab.
2466 * symfile.c (clear_symtab_users_once, cashier_psymtab,
2467 free_named_symtabs): Move these routines from symmisc.c.
2468 * symmisc.c (same): same.
2469 (free_symtab): Make non-static.
2470 * symtab.h (free_symtab): Declare as exported void fn now.
2471 * dbxread.c (end_symtab, end_psymtab): Change comments.
2472 (initialize_dbxread): Call dbx_new_init() in case the first
2473 command is add-symbols.
2474 * target.c (dummy_target): Permit add_syms_addr_command.
2476 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2478 Permit symbols to be superseded when new symbol files have
2479 been read in, particularly for VxWorks.
2481 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
2482 to the main file, as well as to include files. Also, put global
2483 functions into the global psymtab, to make "i fun" work.
2484 (end_psymtab): Free named symtabs and psymtabs for a file, once a
2485 new psymtab for it has been read.
2486 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
2487 a file, once a new symtab has been read for it.
2488 * mipsread.c: FIXME. We need to do the same for MIPS, but it
2489 looks harder to determine the top-level block before it's been
2490 queued to the psymtab list.
2492 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
2493 If we have wiped out any old symbol tables, clean up at end of
2495 (symbol_file_command): Don't reference symfile_fns if it's zero.
2497 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
2498 defines for the blocks of a blockvector that contain global and
2499 file-static symbols and the first of the smaller scope contours.
2500 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
2501 decode_line_1, make_symbol_completion_list): Use the above.
2502 * coffread.c (end_symtab, patch_opaque_types): Ditto.
2503 * dbxread.c (end_symtab): Ditto.
2504 * expread.y (block): Ditto.
2505 * mipsread.c (throughout): Ditto.
2506 * symmisc.c (free_named_symtabs): Ditto.
2508 * symtab.c (list_symbols): Process the first symbol of the
2509 static psymbols list.
2510 (types_info): Restore this function from its untimely #if 0.
2511 It's not perfect, but it is better than nothing.
2512 (_initialize_symtab): Restore "info types".
2514 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2516 * m68k-stub.c: Remote stub for 680x0's, created from
2517 rem-m68k.shar (which is removed).
2518 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
2519 Remove RCS log stuff now that we use CVS and it blows our diffs.
2521 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2523 * symmisc.c (free_named_symtab): Make it work, in its current
2524 kludgy fashion. Change result to indicate if we blew away bkpts.
2525 * dbxread.c (end_symtab): Accumulate result from
2526 free_named_symtab and print warning if we blew user's state.
2527 * symfile.h: free_named_symtab now returns an int.
2529 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
2531 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
2532 is the first symbol read, even if not mainline.
2533 (dbx_psymtab_to_symtab): symfile might be zero, cope.
2534 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
2535 (set_section_command): New command ("section xxx yyy" -- should
2536 be renamed to "set section xxx yyy" FIXME) which sets the
2537 base address of a section of the exec file, overriding the
2538 virtual address that BFD reports.
2540 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2542 * exec.c: Add add_syms_addr_command to exec_ops, so you can
2543 load symbols at any address while examining an exec file.
2545 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2547 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
2548 for printing the float info is host-dependent, not
2549 target-dependent. FIXME.
2550 * i386-pinsn.c: Move #includes to top, remove useless ones.
2551 * i386-tdep.c: Don't bother including <.../reg.h> since we
2552 don't use it (and it doesn't exist on host systems).
2554 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
2555 Convert negative numbers properly.
2556 (ieee_test): Make numbers really random; fix format arg.
2558 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
2559 * core.c (core_detach): Unpush core_ops, which might not be on
2560 top. We used to just pop the top, which broke things. Don't
2561 need dont_repeat() any more.
2562 (core_file_command): Psst! Don't repeat it.
2563 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
2564 * expprint.c (print_subexp): Avoid switch fallthru on
2565 BINOP_ASSIGN_MODIFY, so we can print += and such.
2566 * frame.h: Fix typo.
2567 * inflow.c (kill_command): After killing inferior, print our
2568 current frame in the core file, if we have one.
2569 (generic_mourn_inferior): When inferior dies, either select
2570 the current frame (in the new target, e.g. core file), or
2571 set both the current and selected frames to NULL.
2573 Changes from Peter Schauer.
2575 * infptrace.c: Avoid <sys/ptrace.h> on USG.
2577 * Make all file names fit in 14 characters (sigh and damn!):
2578 mv hp300hpux-xdep.c hp300ux-xdep.c
2579 mv symmetry-xdep.c symm-xdep.c
2580 mv symmetry-tdep.c symm-tdep.c
2581 mv convex-opcode.h convx-opcode.h
2582 mv tm-vxworks960.h tm-vx960.h
2583 mv tm-vxworks68.h tm-vx68.h
2584 mv Makefile.srcdir Makefile.sdir
2585 mv gdb-int.texinfo gdbint.texinfo
2586 mv remote-sa.m68k.shar rem-m68k.shar
2587 mv remote-multi.shar rem-multi.shar
2588 * Makefile.dist, README, config.gdb, convex-pinsn.c,
2589 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
2590 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
2593 * command.c (user_info_1, user_info): New command for listing
2594 the user-defined commands.
2596 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2598 * dbxread.c (really_free_pendings): Clear file_symbols
2599 and global_symbols after freeing them; otherwise, running
2600 this function twice (if it appears twice on the cleanup
2601 chain), we try to free things twice.
2603 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
2604 based on text_addr (the address of text in core), not on addr (the
2605 offset between text in the .o file and in core). This change
2606 is from Peter Schauer.
2608 * main.c: Define ALL_CLEANUPS as a cast of zero.
2609 (return_to_top_level): Use it.
2610 (main): Do all cleanups after each command run as part
2611 of the gdb startup sequence. Also do all cleanups before
2612 entering the command loop, and every time we exit the command
2613 loop and reenter. Before, the cleanups from the startup sequence
2614 were being left undone until the first error!
2615 (command_loop): Rename do_nothing cleanup to command_loop_marker
2616 so we can see it easily when examining the cleanup chain.
2617 (init_signals): Add another do_nothing for signal handling.
2618 (quit_command): Only try to kill target if it has execution.
2619 Problems in the target stack got us into a state where
2620 inferior_pid was nonzero but none of the targets had execution.
2621 In this state you couldn't exit gdb.
2623 * dbxread.c: Two changes from Peter Schauer.
2624 (echo_command): Fflush output after an echo command.
2625 (show_history): Pass all args to cmd_show_list.
2627 * utils.c (init_malloc): Call mtrace to turn on tracing
2628 if the environment variable MALLOC_TRACE is set to a file name.
2629 * mtrace.c: Add source file which provides a log of every malloc,
2630 free, and realloc to a trace file.
2631 * mtrace.awk: Add source file which analyzes the trace file.
2632 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
2633 (VERSION): Roll to 3.94.3.
2635 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
2636 (check_duplicates): Don't bother with watchpoints.
2637 (set_raw_breakpoint): Comment about danger of this routine.
2638 (watch_command): Parse and eval all args before calling
2641 * solib.c (find_solib): Avoid error in referencing memory to
2642 see if any more shared libraries have been added. This is
2643 particularly useful if the target has terminated. Bug reported
2646 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
2647 in bringing up 3.94.2 on the Sun-3.
2649 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
2650 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
2651 expression (in scope) before reenabling watchpoint.
2652 * signame.c (init_sigs): Add missing declaration of i, fix
2653 sys_siglist declaration.
2654 * source.c (list_command): Fixed range computation to use
2656 * stack.c (backtrace_command): Do not allow command if target has
2657 no stack, print informative error message.
2658 * target.c (target_command): Do not write into command line
2659 because this fails if the target command is used in a user defined
2660 command. [This change was enhanced by gnu to support any-
2661 unique-prefix matching on target names.]
2662 * valops.c (value_struct_elt): Avoid infinite loop on an
2663 erroneous attempt to print the member of function (try p main.p).
2665 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2667 * expread.y (name_no_typename): Avoid reduce/reduce errors
2668 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
2669 Since the GDB parser really doesn't use name_no_typename in a
2670 name-only context, the parser can't tell the diff between
2671 names and numbers here. Avoid allowing a name_no_typename
2672 to be a NAME_OR_*INT to resolve the conflict.
2674 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2676 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
2678 * valprint.c (val_print_fields): bitfield printing didn't handle
2679 byte order. Indirect through a few more fns to cope.
2681 * values.c (modify_field): also cope with byte order.
2683 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2685 Cleanup for release 3.94.2:
2687 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
2688 include files. Roll version to 3.94.2.
2690 * coffread.c (init_stringtab): Read length into unsigned char
2691 array before swapping; don't assume 32-bit longs.
2693 * target.c (target_info): Don't bother with get_sym_file, just use
2694 the symfile global variable.
2695 * symtab.h, symfile.c (get_sym_file): Delete it.
2697 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
2698 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
2699 (read_type): Replace one more error() with complain().
2701 * mipsread.c (parse_partial_symbols): Replace printf with complain.
2703 * i960-tdep.c: Fix copyright attribution.
2705 * config.gdb: Quote all backquotes in doublequotes. You can
2706 quote me on that. BSD 4.4 shell found this one.
2708 * infptrace.c (throughout): The third argument to ptrace is an
2711 * infrun.c (wait_for_inferior): When program has terminated, we
2712 have to call target_terminal_ours before we pop that target off
2713 the stack (e.g. before a call to target_kill or
2714 target_mourn_inferior). This fixes problem where a program
2715 terminates, then GDB stops for (tty output) and you have to type
2716 "fg" to the shell to resume it. FIXME: This code for what to
2717 do after termination really should be in normal_stop instead.
2719 * gdbcore.h (read_memory_check): Change declaration; it changed
2722 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
2723 4.4 prereleases, this avoids a bug in their sgtty compatability
2725 * remote.c: Use terminal.h rather than hand-rolling the same.
2727 * signame.c, signame.h (psignal): Arg is unsigned, not int.
2728 * utils.c (strsave, strstr): Fix arg types.
2729 * valprint.c (val_print): lint
2731 MIPS symbol table support from Per Bothner:
2733 * symfile.c (symtab_fns): Remove initializer table that needs to
2734 be hacked for each new symbol file format supported.
2735 (add_symtab_fns): New function, chains symbol table
2736 handlers into the global list.
2737 (symfile_init): Search this list.
2738 * symfile.h: Add next pointer, declare add_symtab_fns.
2739 * coffread.c (_initialize_coffread): Call add_symtab_fns.
2740 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
2742 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
2743 symbol *). Thus, we no longer need the hack to trash
2744 pst->filename. Good, since that hack confused code in symfile.c!
2746 (reorder_symtabs, destroy_all_symtabs): Removed static
2747 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
2748 Instead, the latter now uses a temporary array (stack-allocated
2749 from an obstack, and then freed).
2751 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
2752 haven't been set in the outermost stBlock of a procedure. This was
2753 a problem with f77 binaries on Ultrix 4.?.
2755 (new_symtab, new_symbol, new_type): Continue changing code to use
2756 obstacks more and otherwise conform to dbxread internal style.
2757 Made the free_code of symtabs be free_linetable (as in dbxread)
2758 instead of free_contents. This implies memory leaks when reading
2759 a new symbol table, until the conversion is finished. Did change
2760 (struct symbol) and (struct type) to be allocated on the
2761 symbol_obstack. Blocks and blockvectors are among the things
2764 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
2765 tested much, but it solved one problem (reported by Meissner), and
2766 cleans up some other things. The problem happened when an
2767 included file contains actual code (functions) and not just
2768 definitions. The mips coff is a little inconvenient there, since
2769 it may cause a procedure to be mapped to the wrong psymtab.
2771 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
2772 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
2773 this will need work for the new core paradigm.
2775 Opcode patches from the net:
2777 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
2778 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
2779 missing altogether - they are added here. From Bruce Bauman.
2780 * mips-opcode.h: The low mask for C0 instructions was too small.
2781 From Garrett Lau. I modified the fix to check the entire 32-bit
2784 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
2787 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2789 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
2791 * dbxread.c (read_type): Pointer subtraction (value_sub in
2792 valarith.c) sometimes failed because the types of the
2793 pointers being subtracted were not identical.
2794 These differed because dbxread.c was allocating pointer types
2795 using dbx_alloc_type+smash_to_pointer_type instead of
2796 lookup_pointer_type. I failed to find a justification for the
2797 former, so I changed it to use the latter. Similarly, I
2798 replaced smash_to_function_type by lookup_function_type,
2799 and smash_to_reference_type by lookup_reference_type.
2801 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
2802 _initialize_mipsread): corresponding changes.
2804 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
2806 * source.c (mod_path): Do tilde_expand on each component of the path,
2807 rather than on the (list of) paths as a whole.
2808 (print_source_lines): Set first_line_listed in addition to
2809 current_source_symtab and current_source_line. If the source was
2810 not findable, after a "dir" command to fix the problem,
2811 a "list" would get the wrong lines.
2813 While I was there... (gnu):
2815 * dbxread.c (read_type): Change error to complaint.
2817 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2819 First attempt at detailed understanding of symbol table memory alloc.
2821 * dbxread.c (dbx_symfile_read): Free our string table if we
2822 aren't the mainline. Free the "info" struct since we're done with
2824 (init_psymbol_list): Free any previously allocated psymbol lists.
2825 (): FIXME: Should realloc-down the psymbol lists when done reading
2826 the main symbol file?
2828 * symmisc.c (free_symtab): Free fullname field too.
2830 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
2831 (REGISTER_ADDR): Make result type unsigned int.
2833 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
2834 define REGEX must also define REGEX1 (its dependency).
2836 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2838 * tconfig/i960: No longer works, points you at vxworks960 or
2841 * xgdb.c, XGDB-README: Remove file. Users can get the much
2843 * Makefile.dist: Remove all trace of xgdb.
2845 * breakpoint.c (breakpoint_1): Pass demangle arg to
2846 print_address_symbolic.
2847 (clear_breakpoints): Remove unused function.
2848 (breakpoint_re_set_one): Guts of breakpoint_re_set.
2849 (breakpoint_re_set): Use catch_errors to do them all anyway.
2851 * gdb-int.texinfo (Host versus Target): Add section on what is
2852 a "host" feature versus what is a "target" feature.
2854 * infcmd.c (path_command, path_info): Handle the PATH variable
2855 (object search path) as conveniently as the source search path.
2856 * environ.c (set_in_environ): Set some vars in GDB's environment,
2857 in addition to the child's. PATH, G960BASE, G960BIN for starters.
2858 * source.c (mod_path): New function, from guts of
2859 directory_command, modifies a path. Used by path_command.
2860 (directory_command): Call it.
2861 * defs.h (strsave): Declare.
2863 * utils.c (sevenbit_strings): Add new printing option.
2864 (printchar): Use it.
2865 (strsave): Provide this handy helper routine.
2866 (set_width_command): Rename set_screen_width_command.
2867 (_initialize_utils): "set screen-width" => "set width";
2868 "set screen-height" => "set height"; add sevenbit-strings.
2870 * infcmd.c (do_registers_info): Print floating point registers
2871 in raw hex as well as float format, regardless of whether it is
2872 a "virtual" convertible register.
2873 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
2874 regs as a double, just in case it's being used that way.
2875 * values.c (unpack_long): Comment on array/function coercion.
2876 (unpack_double): Argument is in target byte order now. For
2877 integer arguments, just call unpack_long and float the result.
2878 * m68k-tdep.c: include defs.h for "const" handling.
2879 * remote-nindy.c: Use ieee-float stuff.
2880 (nindy_fetch_registers): Unpack double regs to host double, then
2882 (nindy_store_registers): Pack extendeds to host double, flip
2883 around by misusing unpack_double, send as target double.
2885 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
2886 zero, as when stopped at the first instruction of a process.
2888 * blockframe.c: Fix filename in comment (param.h => tm.h).
2889 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
2890 * tm-68k.h: Fix typos.
2892 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
2894 Changes from a bringup on the DEC Vax under Ultrix 4.0.
2896 * coredep.c (fetch_core_registers): Pass end-address of register
2897 section to register_addr as expected. Don't call supply_register
2898 if we'd just pass it garbage.
2900 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
2902 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
2904 * target.c (push_target, target_info): Cast enums to int for < or
2907 * stack.c (print_frame_info): Identify source file & line
2908 even if we can't print it.
2910 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
2912 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
2914 Clean up IEEE floating point support.
2916 * ieee-float.h: New file.
2917 * ieee-float.c: Write real routines to convert between host
2918 doubles and various target IEEE extendeds.
2919 * m68k-xdep.c: Eliminate assembler code for extended floats.
2920 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
2921 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
2922 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
2923 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
2924 double_to_ieee_extended.
2925 * i960-tdep.c: Define ext_format_i960.
2926 * m68k-tdep.c: Define ext_format_68881.
2927 * sparc-tdep.c: Define ext_format_sparc, though unused.
2928 * Makefile.dist (HFILES): Add ieee-float.h.
2929 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
2932 Obsolete the "coffstrip" program in favor of using BFD's strip.
2934 * nindy-share/coffstrip.c: Remove file.
2935 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
2936 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
2937 * tconfig/nindy960: Remove reference to coffstrip.o.
2939 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
2941 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2943 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
2944 * dbxread.c: Remove static symfile_bfd.
2945 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
2947 * inftarg.c (child_detach): Pop the child_ops vector if the
2948 detach is successful.
2949 * remote-nindy.c (nindy_create_inferior): Don't push a new
2950 nindy_ops since nindy uses the same one for execution and memory
2952 * core.c (core_ops): Use child_attach and child_create_inferior
2953 rather than default attach and create_inferior functions.
2955 Handle floating point registers in core files.
2957 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
2958 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
2959 This version untested since BFD doesn't yet support sun3 core
2961 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
2962 conventions. Fix comments and style. This version has not
2963 been compiled yet, since we have no HP inhouse.
2964 * core.c (get_core_registers): Look for two sections, ".reg"
2965 and ".reg2", and pass both to fetch_core_registers sequentially.
2967 Revise directory path yet again.
2969 * source.c (forget_cached_source_info): Not static any more.
2970 (init_source_path): New default source path is "$cdir:$cwd".
2971 (dir_command): Handle variable arguments ($cdir, $cwd).
2972 (source_info): Print "Compilation directory" rather than
2973 "Originally compiled in" to remind people of $cdir.
2974 (openp): If the path contains $cwd, use current directory.
2975 (open_source_file): If compilation directory is known, replace
2976 first $cdir in path with the compilation directory.
2977 (print_source_lines): Even if we can't print the lines, set the
2978 current symtab and line for future commands like "info source" or
2979 "breakpoint". Also, error message now contains the file name,
2980 line number, and file access error message.
2981 (_initialize_source): Fix help text to describe changes.
2982 * main.c (cd_command): Forget cached source info when we chdir.
2983 * utils.c (strstr): Add simple implementation.
2985 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
2987 * coffread.c (read_one_sym, init_linetable, init_stringtab):
2988 Byte-swap COFF symbol tables if necessary when reading them in.
2989 Use complain() to replace error message in one spot. Needs
2990 corresponding change in bfd/coff-code.h to make some symbol
2991 swapping routines non-static.
2993 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
2995 Merge changes from Eirik Fuller, for UTek.
2997 * defs.h (errno): Add declaration.
2998 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
2999 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3000 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3001 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
3002 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
3003 declarations of errno.
3005 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3007 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3008 <rpc/rpc.h> and <rpc/types.h>.
3010 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3012 * i960-tdep.c (examine_prologue): Add new argument limit,
3013 which stops the scan at the end of the prologue, or at the PC.
3014 This fixes a problem where it walks down into the code for the
3015 user's statements if that code looks like function prologues.
3016 Mark Fox and I have been bouncing this code back and forth, making
3017 small changes to it. Callers changed to match.
3019 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3021 Cleanup for gdb-3.94 release final:
3023 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3024 the .c files from vx-share and nindy-share, from the various
3025 macros, since they are not found via ALLDEPFILES.
3026 (SFILES): Add tm-i960.h.
3027 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3028 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3030 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3031 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
3033 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
3035 * am29k-tdep.c: Add contribution line.
3036 (examine_prologue): Cache information about function prologues in
3037 the misc-function-vector to avoid lots of references over the
3038 serial line while examining instructions.
3040 * core.c (core_close): New function made from cleanup_core.
3042 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3043 remote-vx.c, remote.c, target.c, target.h,
3044 Update target_ops vector to add attach, close, and load entries.
3045 Use add_syms_addr_command, not add_file_addr_command, for
3046 add_file. Break out close routine from existing code.
3048 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3049 they are in an obstack.
3050 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3052 (define_symbol): Add symbol type parameter; change callers;
3053 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3054 it to influence the symbol class on the i960.
3055 (define_symbol): Swap LOC_CONST's into target byte order.
3057 * exec.c (exec_close): New function.
3058 (exec_file_command): Call it.
3060 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3061 Fix byte order of frame pointer.
3062 (read_var_value): Result of 0 if var's value can't be found,
3063 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3064 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3065 (locate_var_value): Use read_var_value and use its lazy address
3066 as the location of the var's value. Lint.
3068 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3071 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3072 obsolete Intel versions in favor of vxgdb versions.
3073 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3074 code dealing with byte order of values, which Intel did in host byte
3075 order rather than gdb-4's target byte order.
3076 (i960_frame_chain_valid): Move to nindy-tdep.c.
3077 (examine_prologue, skip_prologue, frame_find_saved_regs,
3078 frame_args_address, leafproc_return, saved_pc_after_call,
3079 pop_frame): Add vxgdb versions from Mark Fox.
3080 (examine_prologue, frame_struct_result_address): Add code
3081 to deal with the saved value of G13 (struct return address
3083 (frame_args_address): Modify Mark's version to prefer the
3084 saved value over the current value in the topmost frame.
3085 Cache result in the frame info to avoid performance hair in
3087 (print_fault): Add gdb960 code for printing faults.
3088 (_initialize_i960): Actually call check_host.
3090 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3091 add stub routines. FIXME, these currently just return zero!
3093 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3094 (attach_command): Call target_attach, not target_open, now.
3096 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3097 (child_attach): Rename from child_open.
3098 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3099 don't confuse it with a zero step_resume_break_address.
3101 * inftarg.c (child_detach): Eliminate inferior_pid test.
3102 (child_files_info): Clean up message a bit.
3103 (child_ops): Use child_attach, not child_open, to attach.
3105 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3106 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3107 findvar.c to here, since it depends on the contents of the
3108 shadow_contents of breakpoints, but keep if #if 0 since it is
3111 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3114 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3115 (ptype_command, display_command): Eliminate have_inferior_p and
3116 have_core_file_p in favor of target_has_stack or
3117 target_has_execution.
3118 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3119 code for actually finding the values of arguments, though we still
3120 keep track of the maximum stack offset for use in printing unnamed
3121 arguments. Handle missing FRAME_ARGS_ADDRESS.
3123 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3124 (struct nindy_regs): Define registers passed to/from nindy.
3125 (nindy_fetch_registers, nindy_store-registers): Translate between
3126 nindy and GDB formats for the registers.
3127 (dcache_init): Statically allocate the cache, since it was being
3128 allocated by a malloc that was never freed anyway.
3129 (nindy_create_inferior): Error, not core dump, if no exec file.
3130 (nindy_before_main_loop): Use target_load, not target_add_file.
3132 * remote-vx.c (net_load): Specify large timeout for load
3133 requests. Allow user to break out with INTERRUPT.
3134 (net_break): Remove useless code, clean up. Change callers.
3135 (parse-args, skip_white_space, find_white_space): Clean up arg
3136 parsing to cope with quoted strings.
3137 (net_wait, net_quit): Never call error, just return status.
3138 (vx_read_register, vx_write_register): Cleanup status checking.
3139 #ifdef the code based on which CPU we are using (960 or 68k),
3140 FIXME, this should be completely general but it isn't yet.
3141 (vx_xfer_memory, vx_resume): Cleanup status checking.
3142 (vx_run_files_info): Improve message.
3143 (vx_load_command): Renamed from vx_add_file_command. Allow load
3145 (net_ptrace): Remove unused routine.
3146 (vx_wait): Adopt code from vxgdb960 to cope with broken
3147 connections to target machine and prompt to disconnect. Remove
3148 debug printouts. Map some EVENT_'s to SIGnals.
3149 (add_symbol_stub, vx_open): Print names of object files we found,
3150 and "ok" if we read their symbols OK. Clarify output in general.
3151 (vx_attach, vx_detach, vx_kill): Add these commands.
3152 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3153 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3154 "info files" output, and create_inferior, since we already have
3157 * stack.c (frame_info): Replace Frame_unknown with 0.
3158 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3159 (return_command): Pop until the PC matches as well as the FP,
3160 so it works even if the FP is shared with another function,
3161 as in "frameless" or "leaf" procedures.
3163 * symfile.c (load_command): renamed from add_file_target_command.
3164 (add_syms_addr_command): renamed from add_file_addr_command.
3165 (add_syms_command): Stub to call target_add_syms.
3166 (_initialize_symfile): Change command names and descriptions,
3167 add-file => add-syms, and load from alias to its own command.
3169 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3170 maybe_kill_then_create_inferior): Default for attempts to start
3171 a process, if one is already running, is to ask about killing
3172 it and retry if yes.
3173 (upstack_create_inferior): #if-0 it, strata obsolete it.
3174 (push_target, unpush_target, pop_target): to_close() a target
3175 before unstacking it.
3176 (target_info): Renamed from target_files_info.
3177 (_initialize_targets): Rename "i files" as "i target", accessible
3180 * target.h: Improve comments about the target_ vectored routines.
3182 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3183 Convert commenting style to standard GNU style.
3184 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3185 (SKIP_PROLOGUE): No longer a no-op.
3186 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3187 (*_REGNUM): Sort register numbers.
3188 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3189 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3190 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3191 are now 10 byte extendeds, not 8 byte doubles.
3192 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3193 for nindy versus vxworks targets. FIXME, this should possibly go
3194 in the target vector.
3195 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3196 frame_saved_regs and arg pointer with each frame.
3197 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3198 (FRAME_ARGS_ADDRESS): Use cached result.
3199 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3200 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3201 (PRINT_RAMDON_SIGNAL): Call print_fault.
3202 (POP_FRAME): Now works.
3204 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3205 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3206 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3207 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3210 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3211 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3213 * valarith.c (value_subscripted_rvalue): Avoid handling
3214 floats and doubles specially; it gave alignment errors. Lint.
3216 * valops.c (value_of_variable, value_of_this): Error if unknown
3219 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3220 to avoid alignment problems.
3221 (value_print): Handle unknown value address.
3222 (cplus_val_print): Two args are ignored; remove them. Change caller.
3223 (val_print): Use unpack_long rather than pointer-deref.
3226 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3227 to avoid alignment problems.
3228 (value_being_returned): Error if return value unknown.
3229 (set_return_value): Add bogosity warning, FIXME. *
3231 * TODO: A woman's work is never done.
3233 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3234 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3235 Add ieee-float.o to OBS.
3236 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3237 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3238 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3240 Changes to generalize the VxWorks RPC protocol slightly, to handle
3241 i960 as well as 68000.
3243 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3244 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3245 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3246 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3247 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3248 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3249 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3250 so they will move in target byte order rather than network
3251 byte order (happens to be the same).
3253 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3255 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3257 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3260 Add contribution lines to various files, showing where they
3263 * breakpoint.c (break_insn, check_break_insn_size,
3264 read_memory_nobpt): Remove to mem-break.c.
3266 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3269 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3270 entry has bad register number. This change is not
3271 tested in this release, FIXME.
3273 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3276 * value.h: Force value's contents field to be aligned to hold
3277 at least a double or a long long (if supported). This avoids
3278 doing bcopy's in and out of the contents field.
3280 (step_1): Avoid coredump under obscure circumstances when we
3283 * symtab.h (misc_info): Add field to misc function vector for
3284 any kind of cached information the target code desires. AMD
3285 29000 uses this to avoid repeating examine_function_prologue's.
3287 * coffread.c: Lint. Remove static symfile, read_section_header.
3288 core.c (have_core_file_p): Lint: remove.
3289 expprint.c (print_subexp): Lint.
3290 infptrace.c, valops.c, valprint.c: lint.
3292 Roll in changes from vxgdb-5.0.1:
3294 * symtab.h: Comment byte order of each address class. Add
3295 LOC_LOCAL_ARG for frame-relative args (960).
3296 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3297 symtab.c, symmisc.c: ditto.
3299 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3301 * remote.c (remote_resume): Error if resume with a signal.
3303 * symfile.c (prim_record_misc_function): Clear misc_info.
3304 (fill_in_vptr_fieldno): Check stub type of arg.
3306 * valops.c (value_cast): Avoid looking up names of types whose
3307 name we don't know, to prevent coredump. Sun CC produces typedef
3308 rtx and the name of *rtx is zero...
3310 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3312 Roll in changes from final AMD 29000 port (Tiemann).
3314 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3315 for ../include/a.out.encap.h. This might not work now that BFD
3316 is separately compiled. Instead, BFD support for encap will have
3317 to translate machine type 29k into the right COFF_MAGIC.
3319 * infcmd.c: Remove references to inferior_pid that aren't used
3320 in actual ptrace calls; use target_has_execution, etc.
3321 (have_inferior_p): Remove function.
3322 (program_info): Print target info rather than "process number";
3323 avoid gratuitous messages unless from_tty.
3324 (run_stack_dummy, finish_command): Set proceed_to_finish.
3325 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3326 main.c: Lint. Lose have_inferior_p().
3327 inferior.h (have_inferior_p): Remove, lint.
3328 (proceed_to_finish): Add flag to ask that all regs be saved
3329 by normal_stop, for the few commands that need it, speeding up
3330 serial I/O. Add comments to stop_registers.
3332 * remote-eb.c: Remove newline from breakpoint message we grep
3333 for. Never time out when running the user program.
3337 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3339 Roll in changes from vxgdb-5.0.1:
3341 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3342 symbol in its raw form, we are processing an unlinked ".o" file.
3343 See if the target environment has assigned it an address, using
3344 target_lookup_symbol (VxWorks does), and enter it into the symtab
3347 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3348 68k versions for a simpler version that assumes zero FP at bottom.
3349 Fixes bug of truncated stack reports.
3351 * target.h (target_lookup_symbol): Define this routine's args
3352 and result, finally.
3354 * target.c (nosymbol): Default routine for target_lookup_symbol.
3355 (target_default): Default lookup_symbol and call_function too.
3356 (files_info): Only print has_all_memory warning if a non-dummy
3359 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3360 vx_convert_from_virtual): If target does not have floating point,
3361 zero register "values", and avoid doing cross-net conversions.
3362 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3363 (vx_open): Rearrange code that attaches to target and reads
3364 symbols for all loaded modules, to work if some of the modules
3365 are not accessible. Add symbol_stub() and add_symbol_stub()
3366 as callbacks from catch_errors(). Allow connect attempt to be
3367 interrupted painlessly with ^C (FIXME, there are still some bugs
3368 if the interrupt happens during symbol reading.). Print
3369 final message with puts_filtered, since symbol messages are
3374 * main.c (catch_errors): Only print errstring if non-null.
3375 (command_loop): Avoid an ioctl per command to test ISATTY.
3377 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3378 (vx_xfer_memory): Return correct result!
3379 (vx_files_info): Indicate whether target has float or not.
3380 (vx_lookup_symbol): Complain, not error, if target gone.
3381 (vx_open): Print "Connected" msg before disabling immediate-quit.
3382 [FIXME: lookup_symbol and vx_open changes need testing.]
3384 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3385 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3386 contributor lines and update copyrights to 1991.
3388 Changes from an attempted H-PUX host port:
3390 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3391 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3392 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3393 * remote-vx.c: include <sys/time.h> for HPUX.
3394 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3395 "core_file_command" routine to BFD regime. May not work yet.
3397 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3399 * xgdb.c: Replace X10 version with some VJ version.
3400 (FIXME: Its copyright assignment is not on record.)
3401 * xgdb.c: Update include files to X11R4 (Xaw crud).
3402 (xgdb_display_source, create_text_widget): fix call to
3403 get_filename_and_charpos. Rewack source window stuff for X11R4
3404 (gleaned from include files, and "nm's" of binary libraries, since
3405 I had no doc available).
3406 (append_selection, append_selection_word): Disable with FIXME
3407 since R4 changed interface here.
3408 (create_buttons): Add back the old set of buttons.
3409 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3411 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3412 Roll VERSION to 3.94 (not yet final though).
3414 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3416 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3417 obstack_int_grow, obstack_int_grow_fast): Eliminate
3418 cast on left of assignment, which gives MIPS cc fits and is
3421 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3422 F_ALIAS. Use printf, not fprintf, when not passing a file
3424 (compare_opcodes): Check that identical instructions have
3425 identical opcodes, complain otherwise.
3427 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3428 was reported by Roland McGrath.
3429 (unimp): Only match if exactly zero instruction. (Roland)
3430 (branches and traps): Generate all variations of these
3431 instructions with macros, based on a single call that defines
3432 each condition name and its binary representation.
3433 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3435 * valprint.c (val_print_fields): Take, and use, format parameter.
3436 This means that "p/x struct" again prints the elements in the
3437 desired format. Changed callers.
3439 * stack.c (frame_info): Use filtered output, and indicate wrap
3440 points. Remove kludgy formatting designed to avoid line wrap.
3442 * utils.c (wrap_here): If the line is already full (because
3443 we had printed a long indent or long wrapped string), do an
3444 immediate newline-and-indent.
3446 * m68k-pinsn.c (print_insn_arg): Bugfix from
3447 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3448 instruction is incorrectly disassembled as bkpt #8.
3450 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3451 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3452 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3453 and then will dump core (sometimes). I traced it back to an
3454 uninitialized symfile_name in psymtab_to_symtab.
3455 (const_vol_complaint): Add quotes to message.
3456 (define_symbol): Only believe line number if gcc_compiled.
3457 Avoid allocating symbol if we will not return it.
3459 Add target strata support so that newly established targets go
3460 into their right place in the target stack (e.g. a new exec file
3461 doesn't wipe out the ability to access the running process).
3463 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3464 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3465 and initialize it properly in all the targets.
3467 * target.h: Document strata. Change return type of push_target.
3469 * target.c (nomemory): new function for dummy memory access.
3470 (tcomplain): Rename complain, now also used in symfile.c.
3471 (push_target): Push targets within strata. New return value shows
3472 whether new target is on top of stack or not. Always keep dummy
3474 (target_files_info): Ignore dummy target.
3476 * core.c (core_open): Warn user, and skip accessing file, if the
3477 core target is not the topmost target in the stack.
3478 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3481 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3482 target_ops, it doesn't belong there since we have no regs there.
3483 Change name of target from machine => memory to clarify.
3485 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3487 * Freeze version 3.93 for release.
3489 * Makefile.dist: Handle vx-share and nindy-share subdirs
3490 properly when building gdb.tar.Z.
3492 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3493 printed in various places, so I could change just one copy.
3495 * dbxread.c, coffread.c: Change references to bfd->iostream
3496 to cast to FILE *, now that BFD avoids needing types defined
3497 in other header files.
3499 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3501 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3502 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3503 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3504 (actually gcc -Wall).
3506 * dbxread.c: Remove first_global_sym, last_global_sym, since
3507 they are never referenced.
3509 * defs.h (baud_rate): Declare.
3510 main.c: Define it, and add the -b option to set it.
3512 * gdb-int.texinfo: Add text on how to define a new host or target
3513 architecture, prompted by Per Bothner's questions about MIPS
3516 * gdb.texinfo: Document "complaints". Change doc of -q since
3517 gdb no longer prints the copyright and blurb if you specify a file
3518 name to be debugged (just like Emacs). Add doc for Nindy-specific
3519 command line flags for specifying target serial port and such.
3520 Update copyright to 1991.
3522 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3523 has taken over for us the job of ripping up executable files. The
3524 crud caused Per Bothner's port to not compile.
3526 * infrun.c (normal_stop): Avoid printing "Program exited
3527 normally" if we are in batch mode. This allows a GDB which
3528 executes a program on a target system, to behave like a Unix
3529 command (input from stdin, output to stdout, no extraneous
3532 * main.c (main): Allow additional machine-dependent command line
3533 options to be specified with the ADDITIONAL_OPTIONS,
3534 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3535 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3536 processing to occur just before the main loop with
3537 BEFORE_MAIN_LOOP_HOOK.
3538 (main): If a "core file" argument is specified, and it is not a
3539 core file, try it as a process ID to attach.
3540 (symbol_completion_function): Attempt to cope with
3541 "show screen-" TAB, not very successfully. This needs more work,
3543 (batch_file): New function, returns whether we are reading
3544 commands from an interactive tty on stdin, or from somewhere else.
3545 Called by normal_stop since it doesn't get from_tty passed down
3546 to it like many commands do.
3548 * remote-nindy.c: Handle command line options for nindy
3550 (nindy_before_main_loop): Prompt user for tty name if they
3551 don't specify it before getting to the interactive command loop.
3553 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3554 and -r command line options. Also add hook before main loop
3555 to make it easy to specify a tty.
3557 * TODO: More things to do, one done.
3559 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3561 * dbxread.c: Make complaint() calls pass pointer, not struct.
3562 Add complaints about badly formatted C++ type information
3563 (const/volatile indicator, and parse errors resulting in
3564 error_type). Fix C++ virtual member fn comment.
3565 (read_struct_type): Avoid bumping pointer if we got a parse
3566 error; this prevents our walking beyond the end of a string.
3567 Terminate loop on null char as well as semicolon.
3568 (process_one_symbol): Fix the LBRAC fix so that it uses the
3569 last previous SLINE, FUN, or SO record's PC address. C++ debug
3570 symbols did not have SLINE records in a useful order compared
3571 to the LBRAC records.
3572 (define_symbol): Handle "catch" records.
3574 * symtab.c (check_stub_type): Added new complain
3575 `stub_noname_complain' and added a consistency check to
3576 keep the debugger from crashing when finishing from an
3577 exception frame. A real fix will be needed later.
3579 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3581 * infcmd.c (attach_command): Make global.
3583 * Makefile.dist (REMOTE_OBS): Make these compile by default,
3584 but make them easy to comment out. Perhaps later they should
3585 be enabled by what CPU you configure for? FIXME.
3586 (VERSION): Roll to 3.93.
3587 (pinsn.o): Remove rule for obsolete file.
3588 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
3590 Run down a problem that manifested by printing the wrong function
3591 name in stack traces of read_ofile_symtab. Turned out that the
3592 problem was the SunOS 4.1.1 (and previous) C compiler outputs
3593 the LBRAC symbol with an address in the *data* segment, which
3594 blew our binary search through the blocks.
3596 * dbxread.c: Use the complain() facility consistently to bitch
3597 about problems in the symbol file we are reading.
3598 (finish_block): Add code to check the nesting of the blocks;
3599 complain and Procrust them to fit if wrong.
3600 (make_blockvector): Check the order of the blocks, complain
3601 [but don't cope] if wrong.
3602 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
3603 symbols to be sure their PC value is greater than the last SLINE
3604 (line number) symbol we've seen, complaining and adopting the
3605 SLINE PC value if wrong.
3607 * symfile.h (struct complaint, complaint_root, complain,
3608 clear_complaints): Add.
3609 * symfile.c (complain, complaint_root, clear_complaints): Add
3610 facility to deal with non-fatal complaints and to regularize their
3612 (symbol_file_add): Clear complaint counters to allow new complaints.
3613 (initialize_symfile): Add 'set complaints' and 'show complaints'.
3615 * dbxread.c (dbx_symfile_read): Remember the address and size
3616 of the string table for the main symbol file, so we won't read it
3618 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
3619 to avoid reading the string table yet again. Lint.
3620 (throughout): Improve filtered output, including word wrap.
3621 (read_range_type): Improve Bothner's fix to handle other types too.
3623 * utils.c: Improve line wrap implementation. Handle unlimited
3624 width by making chars_per_line unsigned.
3625 (puts_filtered): New, easy, function.
3627 * defs.h (puts_filtered): add.
3629 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
3630 call the identical sort_symtab_syms() in symfile.c instead.
3632 * expread.y: Suggest the `file' command rather than `symbol-file'.
3634 * command.h (enum var_types): Add zinteger for seroable
3636 * command.c (do_setshow_command): Handle var_zinteger. Restructure
3637 nested if's into a switch.
3639 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
3640 we did not stop because of a breakpoint (it must have been for
3641 some other reason, like a "stepi"), so don't print anything.
3643 * symtab.c: Include <sys/types.h> all the time. Now that BFD
3644 doesn't include <sys/types.h>, old SunOS's require it for
3647 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
3649 A test port of gdb-3.92.6 to the Sony NEWS.
3652 Don't normally link in remote- or vx stuff.
3653 Some of it doesn't compile, and it wastes space for 99% of the users.
3654 Remove reference to no-longer-used HAVE_VPRINTF.
3655 Fixed BFD_DEP typo to BFD_DIR.
3657 Fix cast in arg to bfd_h_getlong.
3658 Make char *prefix be const.
3659 Fix how certain range types are mapped into builtin unsigned int types.
3661 Remove 2 #includes. They cause errors (on Sony, at least),
3662 and aren't needed (they wern't in earlier versions).
3664 print_address_symbolic should never demangle labels
3665 (since it prints *assembler-level* labels).
3667 [This was superseded by the change to printcmd below.]
3670 Add some "volatile" return types to avoid warnings.
3671 If MISSING_VPRINTF add vprintf function and not just macro
3672 (since vprintf is used in printcmd.c).
3674 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
3675 (The latter isn't grokked by some PCC-based compilers.)
3677 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
3679 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
3680 * nindy-share/coffstrip.c
3681 Added some forward declarations (otherwise, gcc complains
3682 about implicit extern redefined as static).
3684 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3686 Changes inspired by Per Bothner:
3687 * printcmd.c (print_address_symbolic): Take additional parameter
3688 specifying whether to demangle.
3689 (print_address): Pass in asm_demangle to control demangling.
3690 (print_address_demangle): New fn, takes explicit arg to control
3692 * utils.c: Add new vars demangle and asm_demangle, and let them
3694 (fputs_demangled): If !demangle, just print the argument.
3695 (fprint_symbol): If !demangle, just print raw symbol.
3696 * valprint.c (val_print): Call print_address_demangle rather than
3697 print_address, to cause demangling to depend on the global
3698 rather than assembler-level demangling setting.
3699 * WHATS.NEW, gdb.texinfo: Document.
3701 * main.c (show_command): Show all settings if no arg.
3702 (initialize_main): Make "info set" the same as naked "show".
3703 * command.c (cmd_show_list): Handle prefix commands in the
3704 list, and print the name of the setting as well as its English
3705 description and value.
3707 Allow gdb functions to specify where a line should wrap if it
3708 exceeds the size of a terminal line. Use it to make the output
3710 * utils.c (set_screen_width_command): New fn, mallocs a buffer
3711 of the right size when screen width changes.
3712 (set_screensize_command, screensize_info): Remove #if 0'd fns.
3713 (wrap_here): New fn, indicates a point in the output where we
3714 should wrap the line rather than just letting it overflow at a
3716 (fputs_filtered): Implement wrapping.
3717 (n_spaces): New fn, returns a pointer to N spaces.
3718 (print_spaces_filtered): Use n_spaces.
3719 * defs.h (n_spaces): Declare.
3720 * stack.c (print_frame_info): Wrap with 4-space indent after
3721 fn name and before filename and line number.
3722 * printcmd.c (print_frame_args): Wrap with 4-space indent
3723 before each argument name is printed.
3724 * valprint.c (value_print): Wrap with no indentation before
3726 (val_print_fields): Wrap with indentation relative to nesting
3727 level before each field name.
3728 (val_print): Wrap with nesting indentation before array elements.
3729 * command.c (do_setshow_command): Avoid extra newlines,
3730 wrap with 4-space indent around values printed, end with period.
3731 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
3733 * breakpoint.c (breakpoint_1): Implement addressprint for
3734 "info breakpoints" display. Change file name and line number
3735 format to " at file:nnn" rather than " (file line nnn)".
3736 * gdb.texinfo: Document.
3739 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3741 Frozen for gdb-3.92.6 release.
3743 README, WHATS.NEW: Update for 3.92.6 release.
3745 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
3746 coffread.o from configs since it is now built by default.
3747 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
3748 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
3749 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
3750 from configs since it is now built by default.
3752 Makefile.dist: Update for release 3.92.6. Handle files that
3753 have been moved to ../include, ../getopt, or ../bfd. Add
3754 saber.suppress and tests directory. Add config.status to
3755 the release (it will say "none").
3757 coredep.c: Minor formatting fixes.
3759 These changes were made in early December but only checked in now:
3760 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
3761 nindy-share/nindy.c: lint
3762 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
3763 register values coming back from the target; we store values
3764 in target byte order everywhere.
3766 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
3768 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
3770 * valprint.c (cplus_val_print, val_print_fields): New functions,
3771 which print C++ objects. They conspire to avoid printing a
3772 virtual base class more than once, following all the twists and
3773 turns of C++ virtual base rules.
3774 (val_print): Call the above rather than do it by hand.
3776 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
3777 symbol file, not for added files like shared libs. This really
3778 needs to be generalized to a timestamp per file.
3780 * core.c (cleanup_core): Avoid coredump if no core file.
3782 * config.gdb: Accept -host or -target in place of +host or
3785 * coffread.c (find_linenos): Avoid desupported BFD interface
3786 to line numbers. We still read them manually rather than using
3787 BFD's "generic" features.
3789 * gdbrc.tex, threecol.tex: Add GDB reference card and its
3791 Makefile.dist: Add refcard to OTHERS list for creating tar files.
3793 * Makefile.dist: Eliminate use of $< in explicit targets.
3795 * readline/Makefile: Use $< rather than $*.c, which does not
3796 include the VPATH in GNU Make.
3798 * tconfig/i960-bout, tconfig/i960-coff: These are identical
3799 copies of tconfig/i960, added for global configuration
3800 compatability. All i960 versions can read both coff and b.out.
3802 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
3803 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
3806 * TODO: Think of more things to do.
3808 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
3810 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
3811 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
3812 64-bit float conversion.
3814 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
3815 equivalent to sun?os4 so global config works.
3817 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
3819 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
3821 * main.c: Only declare linesize once; declare pagesize not at
3822 all, since it is never used.
3823 (main): Clear newly allocated line before it is used.
3825 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
3827 Further stabilization for the Intel 960.
3829 * Makefile.dist: Parameterize the location of the "include"
3830 and "bfd" directories, as well as "getopt". Add symfile.c.
3831 Link in both dbxread and coffread. Fix up "make depend" to
3832 rewack the locations of include, bfd, and getopt in its output.
3834 * README: Document moving include files, improve some of
3837 * coffread.c: Move common code out to symfile.c. Change
3838 symbol_file_command style interface to use new *_symfile_init
3839 and *_symfile_read interface under BFD. Use BFD internal
3840 info to locate line table, symbols, etc.
3842 * core.c (core_fetch_registers): Rename to get_core_registers
3843 to avoid confusion with fetch_core_registers.
3844 (register_addr): Move to coredep.c, which is already machine
3845 dependent. This leaves core.c pretty clean of dependencies.
3847 * coredep.c (register_addr): Accept this routine from core.c.
3849 * dbxread.c: Move common code (with coffread.c, etc) into new
3850 symfile.c. Each psymtab now contains a pointer to the
3851 format-dependent function that knows how to read it in. Make
3853 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
3854 (process_one_symbol): Add code to complain about a "compiler bug
3855 we muzzle here", if we actually see it.
3857 * eval.c (evaluate_subexp): Insert missing "break" statements
3858 in code that determines whether a variable is an lvalue in
3859 memory, register, or whatever. I detected this via a compiler
3860 bug in which it *almost* mashed out the whole switch statement.
3862 * gdb-int.texinfo: Add minor sections on configuring gdb for
3863 release, and about the README file.
3865 * infcmd.c (registers_info): Fix formatting somewhat. Still
3866 not as pretty as before, but it handles byte swapping.
3868 * remote-nindy.c: If data cache routines are interrupted while
3869 waiting for the remote end, be sure that any uninitialized cache
3870 blocks are on the free list, not on the valid list!
3872 * symfile.h: Flesh out this header file with all the various
3873 routines and variables that have been merged in from dbxread.c
3874 coffread.c, and symtab.c to symfile.c.
3876 * symfile.c: New file, containing code common to dbxread.c,
3877 coffread.c, and some code from symtab.c. All generic code for
3878 reading symbol files should be in here now.
3879 (unrecord_misc_function): Remove unused function.
3881 * symtab.h: Remove file-reading things to symfile.h.
3883 * symtab.c: Remove file-reading things to symfile.c.
3885 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
3886 to decode i960 fault types.
3888 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
3889 target.c: Change type of the "resume" function from int to void,
3890 since its result was never used.
3892 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
3894 * main.c: Replace "stupid" with "caution"; you now "set caution
3897 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
3899 * infcmd.c (do_registers_info): Call val_print to deal with the
3900 byte order of the registers being printed. FIXME, this makes
3901 the formatting of the output uglier.
3903 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
3904 defined, call it for signals the debugger doesn't itself use.
3905 The i960 uses this for more detailed fault information.
3907 * remote.c (remote_open): If arg is null, print help rather than
3910 * sparc-xdep.c (register_valid): Avoid declaring size, since
3911 various modules will think of various sizes depending on the
3912 architecture of their tm-file. FIXME, we need protection against
3913 actually entering one of those modules, which would clobber
3914 storage if not for the target architecture compiled into gdb.
3916 * stack.c (up_command, down_command): Always print the frame
3918 (up_silently_command, down_silently_command): New commands
3921 * i960-pinsn.c (reg), i960-tdep.c: Lint.
3923 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
3924 more parameters than it used to.
3926 * findvar.c (registers): Increase slop to 256 bytes, which should
3927 protect us against even most RISC machines with large register
3929 (locate_var_value): Move declaration inside related ifdef.
3931 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
3932 throughout, to avoid throwing away buffered input from the board.
3933 (nindy_wait): Supply_register takes addr_of_value, not value.
3934 (i960_print_fault): Renamed from i80960_fault.
3935 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
3936 (nindy_store_registers): Avoid regs_changed stuff, just stuff
3938 (nindy_create_inferior): Don't bother to write PC_REGNUM since
3939 we can set the PC in the call to proceed(). Unpush nindy_ops
3940 before pushing it on top, to avoid message to user. Eliminate
3941 commentary from Unix machines that just misleads here.
3942 (reset_command): Fix error message to suggest target command.
3944 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
3946 Release 3.92.5 as frozen.
3948 Stabilize the merged release...with help from lint, Saber C,
3951 Everywhere: Add include files needed to declare return types
3952 of functions called.
3954 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
3956 * breakpoint.h: Add undeclared breakpoint functions, and some
3957 functions for display handling since I couldn't think of a better
3960 * breakpoint.c (insert_breakpoints): Make code for disabling
3961 shared library bkpts more likely to work. It's used when we
3962 rerun a program and stop before the shared library has been
3964 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
3965 cast from pointer, so it squeezes through catch_errors.
3966 (bpstat_stop_status): Fix logic broken some time ago. We now
3967 always create a bpstat if the stop address matches a breakpoint,
3968 even if we don't stop there -- just like the old code used to do
3969 before I got my fingers into it (sigh).
3970 (breakpoint_1): Print "ignore count" after "stop only if"
3971 condition, since that's how it actually works.
3972 (mention): Handle watchpoints as well as breakpoints.
3973 (watch_command): use set_raw_breakpoint and mention to do most
3974 of the work (and initialize all the fields!). Only pass one
3975 arg to parse_c_expression, since that's all it takes.
3977 * command.c (not_just_help_class_command): Rename arg to args
3978 since we ignore "unused argument" warnings on vars named "args".
3979 inflow.c (child_terminal_info): ditto.
3980 infptrace.c (kill_inferior): ditto
3981 main.c (catch_errors, version_info, quit_command, pwd_command,
3982 source_command, dump_me_command, editing_info,
3983 set_history_size_command, set_history, show_history,
3985 stack.c (locals_info): ditto
3986 target.c (target_files_info): ditto
3987 valprint.c (set_input_radix, set_output_radix): ditto
3989 * core.c: Remove old variables for handling core and exec file
3990 sections (data_start, data_end, stack_start, stack_end,
3991 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
3992 text_end, exec_data_start, exec_data_end, text_offset,
3993 exec_data_offset, data_offset, stack_offset). They're
3994 superseded the more general build_section_table and
3996 (get_exec_file): Mention the `file' command.
3997 (read_memory_check): Rename to memory_error, and only call it
3998 in the case of an actual error.
3999 (read_memory, write_memory): call memory_error.
4000 (core_fetch_registers): Register section name is ".reg".
4002 coredep.c: Remove a bunch of crud now that all this file does
4003 is pull the registers out of a core file.
4004 (fetch_core_registers): Rewrite to actually work, I hope.
4006 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4007 Replace index() with strchr(). Remove all the pre-BFD macro
4008 definitions for accessing the symbol file.
4009 (struct dbx_symfile_info): Encapsulate the information that
4010 dbx_symfile_init needs to pass to dbx_symfile_read in this
4013 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4014 dbx_symfile_discard): Rearrange symbol file reading to divide
4015 the format-specific part from the format-independent part,
4016 leaving the format-independent part such as file name expansion
4017 and opening in symtab.c. This replaces
4018 partial_symbol_file_open and partial_symbol_file_read.
4019 Symbol_file_read, add_file, add_file_target_command,
4020 add_file_addr_command move to symtab.c. Pass an explicit
4021 "mainline" flag for when reading the main symbol table, rather
4022 than relying on the offset address to be zero or nonzero.
4024 (dbx_symfile_read): Don't allow void *'s to be printed as
4026 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4027 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4028 macro" debug version really work.
4029 (read_dbx_symtab): Remove unref'd parameter inclink.
4030 Avoid swapping N_SLINE symbols, for speed.
4031 Merge N_TEXT!N_EXT case with the other external symbol
4032 definitions' case. Add comments.
4033 (start_psymtab): Allocate the symfile name in the psymtab on
4034 the psymbol_obstack, rather than using the caller's storage.
4035 (end_psymtab): Only allocate a dependencies list if there are
4037 (psymtab_to_symtab_2): Use BFD when reopening file to read
4038 its symbols for real.
4039 (read_struct_type): Add FIXME comments where it needs work
4041 (read_huge_number): Add FIXME about overflows.
4042 (read_range_type): Add FIXME about comparing a long to 1<<32.
4044 * coffread.c: Minor changes to move things closer to the new
4045 regime with symtab.c and dbxread.c Major work is still needed
4048 * exec.c (exec_file_command): Remove old variables (see core.c
4050 (xfer_memory): If memory transfer is right at the end of a
4051 section, don't lose.
4053 * findvar.c (get_saved_register): If value is in a real
4054 register, LVAL is lval_register, not lval_memory.
4056 frame.h: Declare print_sel_frame and record_selected_frame.
4058 gdb-int.texinfo: New file, for GDB internals documentation.
4059 Very simple, unformatted doc of cleanups is there for now.
4061 gdbcore.h: Remove obsolete variables that described a.out
4062 section addresses and offsets. (See core.c above.)
4063 Declare fetch_core_registers and registers_fetched.
4065 getopt.c: Declare char *alloca(); even on SPARC.
4067 infcmd.c (run_command): Call target_kill rather than
4069 (step_command, next_command, stepi_command, nexti_command):
4070 Declare from_tty parameter even though we don't use it.
4071 (run_stack_dummy): argument BUFFER is a char array, not
4072 a pointer to REGISTER_TYPE.
4073 (finish_command): using_struct_return needed a value *,
4074 not a struct symbol *.
4076 * infptrace.c (child_xfer_memory): To avoid dependency on
4077 where sections are in memory, try PT_WRITE_D and if that fails,
4078 try PT_WRITE_I. Most Unixes don't care which you use.
4080 * infrun.c (step_resume_break_shadow): Change to array to
4081 match other breakpoint shadow storage.
4082 (clear_proceed_status): Pass address of bpstat to
4083 bpstat_clear, not the bpstat itself.
4084 (child_create_inferior): FIXME comment about if the child
4086 (start_inferior): Remove old function.
4087 (child_open): Use target_kill rather than kill_inferior.
4088 (wait_for_inferior): Ditto.
4089 (insert_step_breakpoint, remote_step_breakpoint): Use
4090 new step_resume_break_shadow.
4092 * inftarg.c (child_wait): If all child processes die,
4093 pretend that the one being waited for exited with signal 42.
4095 * main.c (command_line_input): When scanning for comments,
4096 don't coredump on unclosed quotes.
4097 (quit_command): Use target_kill rther than kill_inferior.
4098 (_initialize_main): Rename class_user from "user" to
4101 * printcmd.c (print_command_1): Initialize "fmt" if no format
4102 is specified by the user.
4103 (print_frame_args): Only add to args_printed if we are
4104 actually fetching args from the stack (avoiding undefined
4106 (_initialize_printcmd): Remove bogus \{ from string.
4108 * remote-eb.c (eb_open): Avoid coredump on no argument.
4110 * remote-nindy.c: Bring out of Intel environment into new
4111 target environment. Remove all conditional compilation on
4112 I80960. Massive hacking throughout.
4113 (nindy_xfer_inferior_memory): New routine stolen from
4115 (nindy_create_inferior): New routine pieced together, probably
4116 not quite working yet.
4117 (nindy_ops): New target_ops struct for nindy.
4119 * remote-vx.c: Use write_memory rather than target_write_memory
4120 to get error checking.
4121 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4123 (vx_create_inferior): Use target_terminal_ours...
4125 * signame.c (_initialize_signame): Always initialize, since
4126 we need the table for things other than psignal.
4128 * solib.c (solib_add): Use symbol_file_add, not add_file.
4129 (solib_address): Return boolean result rather than struct
4130 pointer which nobody else knows the type of.
4132 * sparc-tdep.c, valops.c: Use write_memory rather than
4133 target_write_memory, to get error checking.
4135 * stack.c (locals_info, catch_info, args_info,
4136 get_selected_block, frame_command, up_command): Use
4137 target_has_stack, rather than have_inferior_p or
4140 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4142 * symfile.h: New file, defining the interface between the
4143 generic and object-file-specific symbol reading code.
4145 * symtab.c: Move generic symbol-reading interface to symtab.c,
4146 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4147 table to map BFD targets to symbol-reading modules in GDB.
4148 Change index to strchr.
4149 (lookup_struct_elt_type): Use error() rather than hand-made
4150 simulations thereof.
4151 (lookup_partial_symbol): Speedup slightly when length == 0.
4152 (symbol_file_add): New function.
4153 (symbol_file_command): Call it.
4154 (symfile_open, symfile_init): New function.
4155 (add_file_target_command, add_file_addr_command): moved from
4158 * target.c (target_command): use target_kill.
4160 * target.h (target_files_info): Don't declare, never called
4163 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4164 files to determine stack end address.
4166 * valarith.c (value_x_binop, value_x_unop): Change error message
4167 to be more useful. Pass proper argument to value_struct_elt.
4169 * valops.c (value_assign): FIXME comment that long long
4170 bitfields will break here.
4172 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4173 Update `make saber_gdb' to work better.
4175 * TODO: A woman's work is never done.
4177 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4178 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4179 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4180 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4181 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4182 valops.c, valprint.c, exec.c: Lint.
4185 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4187 Continuing Intel 960 port merge of GDB.
4189 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4190 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4191 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4192 Wack over "make depend" so it handles files in subdirectories
4193 vx-share, nindy-share, bfd, and in the current directory.
4195 * blockframe.c (get_prev_frame_info): Remove fatal error
4196 if stack not defined.
4198 * core.c (core_open, core_detach): New functions that handle
4199 the old "core-file" command as "target core" and "detach" instead.
4200 (core_file_command): Call them.
4201 (core_xfer_memory): Use common routine xfer_memory.
4203 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4204 dbxread now uses bfd for everything but symbol reading itself.
4205 BFD internals are used to drag out the relevant file offsets.
4206 (partial_symbol_file_open): Change args all around for BFD.
4208 * symtab.c: Rename "value" to "val" everywhere, so we can
4210 (symbol_file_command): New command, moved from dbxread.c
4211 and coffread.c. It uses BFD to read the file, then vectors
4212 based on its type, to dbx or coff symbol readers.
4213 * symtab.h: Extern a few vars for symbol_file_command.
4215 * target.h: Breakpoint takes a char * save area, not a char **.
4217 * valprint.c (val_print): When unpacking bitfields, offset
4218 the address in gdb of the value, if it is declared with a shorter
4219 type. Remove the last "runtime kludge test" of host byte order.
4221 * utils.c: Remove old my_bfd_read routine.
4223 * stack.c (frame_info): Use target_has_stack. Print program counter
4224 register's actual name rather than "pc", since it's called the
4225 "ip" (instruction pointer) on the i960 (sigh).
4227 * target.c (target_command): Add command for selecting a target
4228 type and calling its open routine. This is used for initiating
4229 communication with a particular target, in a generic way.
4231 * tm-i960.h: Update for modern gdb. Remove semicolons from
4232 various macros. Handle reading struct return convention, and
4233 error-out attempts to return structs with the "return" command.
4234 Be sure gdb doesn't think we know how to call functions in the
4237 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4238 to i960_xxx in lower case.
4239 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4240 not being defined yet.
4242 * remote.c (remote_open): Call start_remote to initialize
4243 wait_for_inferior during open.
4244 (remote_xfer_inferior_memory): Return length written rather
4247 * remote-vx.c (target_command -> vx_open): Use new generic
4249 * remote-eb.c, inftarg.c, exec.c: ditto.
4251 * infrun.c: Fix comments.
4252 (attach_program -> child_open): Use new generic target command.
4253 (wait_for_inferior): Clear saved register values before target_wait,
4254 so target_wait can set some of them if convenient.
4256 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4257 Return success indicator, not void.
4258 (child_xfer_memory): Avoid fetching initial word if we'll
4259 overwrite it anyway.
4261 * infcmd.c (attach_command): Use new generic target open routine.
4262 (_initialize_infcmd): Update doc on attach and detach commands.
4263 (do_registers_info): Merge in a byte-order problem as a FIXME
4266 * findvar.c (find_saved_register): Avoid problem in current frame.
4267 (read_relative_register): Ditto.
4268 (write_register): Convert byte order on the way out.
4270 * exec.c (file_command): Add.
4271 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4272 (xfer_memory): Common function between core_xfer_memory and
4274 (exec_xfer_memory): Use it.
4276 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4278 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4279 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4280 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4282 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4284 Merge Intel 960 port of gdb, continuing...
4286 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4287 symbol_file_command): Pass from_tty arg to hush 'em up.
4289 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4290 Add magic numbers for 960 COFF format.
4292 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4294 Merge Intel 960 port of gdb, from Intel "1.2" release.
4296 CHANGE_LOG entries from their port, which was based on
4299 Thu Sep 6 11:02:22 PDT 1990
4300 Remove temp file if download is interrupted.
4302 Wed Aug 1 09:08:33 PDT 1990
4303 Now uses binary protocol to talk to NINDY.
4304 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
4305 Times out after 5 seconds when trying to talk to NINDY.
4307 Tue May 29 12:54:49 PDT 1990
4308 Added variable baud rate (-b switch).
4309 Source code reorganization.
4311 Thu Apr 26 11:09:55 PDT 1990
4312 More cleanup of batch mode; specifically, execute "-s", "-e", and
4313 "-se" switches as soon as they are encountered on the invocation line.
4315 Fri Apr 20 13:47:15 PDT 1990
4318 Thu Apr 19 09:54:28 PDT 1990
4319 Add 'reset' command.
4321 Wed Apr 18 09:48:07 PDT 1990
4322 After opening remote tty, wait for 1 second to go by without input
4323 from it before trying to talk to NINDY (fixes problems with the
4324 Heurikon HK80/V960E).
4326 Mon Apr 4 16:33:05 PDT 1990
4327 Some output was not being suppressed in 'batch' mode.
4329 Thu Mar 22 15:31:11 PST 1990
4330 Ask user if old symbol table should be deleted when new file is
4333 Allow user to run a program downloaded before gdb960 was brought up.
4335 Correct "exec-file" help message for i80960 context.
4337 Correct bug in calculating user space address: could occasionally
4338 corrupt user program.
4340 Make sure to zero low-order bits in rip's because of bug in 960CA
4341 A-step part: could cause operation faults when "next"ing across
4344 Correct bug that made it impossible to get source line numbers for
4345 code loaded at addresses higher than 0x7fffffff.
4347 Wed Jan 10 12:43:22 PST 1990
4348 Open remote tty for exclusive use.
4350 Fri Jan 5 12:14:42 PST 1990
4351 Correct disassembly (CA manual was right after all):
4352 opcode for sysctl is 0x659
4354 Mon Oct 23 12:03:04 PDT 1989
4355 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4357 Mon Oct 16 14:15:09 PDT 1989
4358 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4360 Mon Oct 2 15:56:31 PDT 1989
4362 Added 960CA disassembly support.
4364 To simplify maintenance:
4365 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4367 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4368 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4369 - made disassembly interface identical to that in gdmp960.
4373 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4375 * target.h: Allow targets to stack. Add target_has_memory,
4376 _registers, etc. Restructure memory access and "info files"
4377 to walk the target stack.
4378 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4379 target.c: Change tables to match target.h.
4380 * inflow.c (child_mourn_inferior): pop child_ops.
4381 (generic_mourn_inferior): Use new has_stack flag.
4382 * infptrace.c (child_xfer_memory): New memory regime.
4383 * inftarg.c (child_files_info): New "info files" regime.
4384 * remote-eb.c: New memory regime, new info files.
4385 * remote-vx.c: New memory regime, new info files. Now use
4386 separate targets for VxWorks attachment to machine, and
4387 actually running a process under VxWorks, since one has
4388 stack & execution & regs and the other doesn't.
4389 * remote.c: New memory regime, new info files.
4390 * sparc-xdep.c (fetch_core-registers): New memory regime.
4391 * target.c: New routines and support for stacked targets,
4392 new memory regime, new info files regime.
4395 Generalize section handling for an arbitrary number of sections,
4396 including use of the new BFD (binary file) library.
4397 * gdbcore.h: Add struct section_table.
4398 * exec.c (build_section_table): Iterate all sections and
4399 record what gdb needs to know about them.
4400 (exec_command): Use it.
4401 (exec_xfer_memory): Use the table.
4402 (exec_files_info): Print the table.
4403 * core.c (core_file_command, core_xfer_memory, core_files_info):
4405 * source.c (find_source_lines): Use bfd_get_mtime.
4406 * dbxread.c: Quick changes to make it compile with new BFD.
4407 * utils.c (error): Avoid using bfd_error in generic routines.
4409 * core.c (core_fetch_registers): Get from the ".regs" section of
4411 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4413 * inferior.h (attach_flag): Export.
4414 * infcmd.c (run_command): use new target_create_inferior.
4415 * infrun.c (child_create_inferior): Don't return result.
4416 * Makefile.dist (VERSION): 3.91.4.
4418 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
4420 * breakpoint.c (bpstat_num): Handle breakpoints which have
4421 since been deleted, such as temporary breakpoints.
4422 infcmd.c (program_info): ditto.
4424 * core.c (core_file_command): Display the frame where the core
4429 * remote-vx.c (target_command): Merge in target command from
4430 targ-vx.c. A few other cleanups.
4432 * TODO, Projects: Lots more stuff to do...
4434 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4436 Massive changes to wall off the remote-debugging interface
4437 behind a function vector. The port to handle VxWorks targets
4438 is also part of this.
4440 All files: Replace references to renamed functions,
4441 remove references to remote_debugging, remove references to
4442 have_include_file, have_core_file in favor of target_has_stack,
4443 target_has_memory, etc.
4445 * Modularize the breakpoint interface.
4446 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4447 a breakpoint instruction.
4448 breakpoint.c: struct breakpoint's shadow_contents now sized as
4450 (insert_breakpoints): Vector to target to install breakpoints.
4451 (remove_breakpoints): Vector to target here too.
4452 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4453 sparc-tdep.c (single_step): Use new breakpoint interface for
4454 the single-step breakpoints.
4455 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4456 New file, contains routines to insert and remove breakpoints by
4457 reading out the old contents and later replacing them. This is
4458 how ptrace breakpoints work, and many remote systems as well.
4460 * tm-vxworks68.h: New config file, overrides a few things for
4461 Wind River's preferences.
4463 * target.h: New file, for transfer vector used to talk to the
4464 inferior (child, attached, core, exec, remote, etc). All accesses
4465 to the thing being debugged should come through these vectors.
4466 target.c: New file, routines to handle transfer vector.
4467 (various files): Add transfer vectors XXX_ops for the various
4468 targets and pseudo-targets (core files, etc) we support.
4470 * breakpoint.c (bpstat_stop_status): Further explorations of
4471 watchpoints and why things don't work all the time.
4472 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4474 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4475 the local gdbinit if it doesn't already have it.
4477 * core.c (core_ops): add and install.
4478 Allow core debugging without exec file.
4480 * dbxread.c (free_and_init_header_files): Merge two fns.
4481 (end_symtab): Free named symbol table when a new version comes in.
4482 (read_dbx_symtab): Relocate all kinds of symbols with base
4483 address. First step toward handling different text, data, bss
4485 (add_file_addr_command): Renamed add_file_command.
4486 (add_file_command): Vector to remote handler.
4487 Add "load" as an alias for "add-file" command.
4489 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4490 non-returning functions.
4492 * exec.c: Add exec_ops, and push it as a target when an exec
4495 * infcmd.c (run_command): Pass executable file name and arg list
4496 separately when starting an inferior. Permit "run" when no exec
4497 file is specified, for VxWorks.
4498 (detach_command): Move to child_detach in inftarg.c.
4500 * inftarg.c: New file. Unix-child-specific routines, and the
4501 child_ops structure.
4503 * inferior.h (registers): Export "registers" as the way for
4504 target dependent register handlers to find gdb's local copy of
4505 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4506 since it is now used by places that want wait_for_inferior to
4507 handle the grunge but want to see every trap from the inferior.
4509 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4510 Eliminate remote_debugging hooks in terminal handling.
4512 * infrun.c: Replace start_inferior with child_create_inferior.
4513 Move all the hair of Unix shells and ptrace idiosyncracies into
4514 child_create_inferior, so remote handlers don't have to deal.
4515 Remove running_in_shell. Rename stop_after_attach to
4516 stop_soon_quietly, and use it in a few other places where we want
4517 to just call wait_for_inferior and get control back on the first
4518 trap. trap_expected now never takes a value > 1.
4519 (init_wait_for_inferior): Initialize static vars when a new
4522 main.c (gdbinit): Add new hook for .gdbinit file name, let
4523 it be overridden by config files as GDBINIT_FILENAME.
4524 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4525 Both of these are used for VxWorks gdb.
4527 mcheck.c: rename include file "gmalloc.c" to avoid problems
4528 with system include file "malloc.c".
4530 param-no-tm.h: New include file, same as param.h but does not
4531 include the default "tm.h" file. This is used in files where
4532 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4534 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4536 remote-vx.c: New file, VxWorks remote debugging support. Uses
4537 RPC routines that are shared with the target system, in directory
4540 remote.c: Vectorize remote interface.
4542 source.c: Globalize source_path, and make an alias "l" for "list"
4543 since we now have the "load" command.
4545 sparc-xdep.c: Use new param-no-tm.h.
4547 symmisc.c (free_named_symtab): Add new function from Wind River.
4548 However, ifdef it out for now while we think about what it should
4551 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4553 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4554 non-Unix-children handle this with their own code in the target
4557 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4558 source and target lists. Add vx-share to default list of include
4559 directories. Add new files to src and target lists: mem-break,
4560 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4561 ${srcdir} versions of munch and createtags are used.
4563 * valops.c (find_function_addr): Split out of call_function.
4564 (call_function_by_hand): Rename call_function; this function
4565 calls functions in the target by laboriously patching the target
4566 word-by-word with the right stack, args, regs, etc.
4569 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
4571 Handle AMD 29000 a bit better.
4573 * remote-eb.c (readchar): Mask received char log to make it readable.
4574 (remote_start): Pass arguments down to executing program.
4575 Make startaddr unsigned.
4576 infrun.c (start_inferior): Accept args, pass them to
4578 infcmd.c (run_command): Pass args down to start_inferior.
4580 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
4581 the target object file format.
4582 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
4584 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
4585 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
4587 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
4589 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
4590 * TODO: We did a few things, we have more to do though.
4592 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
4593 * inflow.c (inferior_died): Clear deferred stores.
4595 * Debug problems with dummy frames and calls to the inferior.
4596 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
4597 * sparc-tdep.c (do_restore_insn): Simplify.
4598 (sparc_frame_find_saved_regs): Simplify and fix what we find.
4599 (sparc_push_dummy_frame): Simplify and fix what we push.
4600 (sparc_pop_frame): Slightly more hair here, deciding whether
4601 we are restoring a saved PC or returning to a return address in %i7.
4602 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
4604 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
4605 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
4606 * obstack.h (chunkfun): ditto.
4607 * defs.h (xmalloc, xrealloc): ditto
4609 * utils.c (quit): Grab the terminal from the child if necessary.
4611 * inflow.c (term_status_command): Rename to term_info, change
4614 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
4615 (is_delayed_branch): Speed up.
4616 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
4617 Still missing some float ops, and needs testing.
4619 * Support for input and output radixes other than base 10
4620 * defs.h (input_radix, output_radix): Declare.
4621 * expread.y (yyparse, parse_number): Handle changes of input
4622 radix, and ambiguous names-or-numbers in radixes >10.
4623 * printcmd.c (print_scalar_formatted): Print formatted hex
4624 numbers in varying column widths.
4625 * valprint.c (val_print): Use output_format to print scalar ints.
4626 (set_input_radix, set_output_radix, set_radix): Create.
4627 (set_output_radix): Set output_format from output_radix.
4628 (_initialize_valprint): add `set radix' but leave the others off.
4630 * main.c (execute_command): Let stupid questions be turned off.
4631 (_initialize_main): Handle "set stupidity", etc.
4633 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
4634 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
4636 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
4638 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
4639 bfd stuff is still screwed up, but with some manual work, it
4642 * breakpoint.c (bpstat_do_actions): Start over if a command
4643 proceeds the inferior, since the inferior will have stopped and
4644 will need to have its new stop-actions taken care of.
4646 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
4647 compiler fits, simplify it.
4649 * gdb.texinfo (directory command): Doc new dir command.
4650 source.c (directory_command): "dir" now puts things on the front
4651 of the path, moves dups up front, and handles multiple names
4652 on the command line, inserting each one in order. It also
4653 blows away cached line and full_filename info.
4655 * stack.c (backtrace_command): Skip "more stack frames follow"
4658 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
4659 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
4660 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
4661 The only odd one was Gould NP1, which had defined vprintf to
4664 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
4665 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
4666 variable, inspect_it.
4667 valprint.c (print_string, val_print): Use the global inspect_it
4668 to indicate whether to print in Epoch style or normal style.
4670 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
4672 * printcmd.c (call_command): add an alias for the "print" command
4673 which runs expressions and doesn't print the result if void.
4674 (print_command_1): implement it.
4676 * command.c: Remove #if 0'd code. Initialize all the fields
4677 in add_cmd (). Rename do_nothing_command to
4678 not_just_help_class_command, and make it externally visible.
4679 command.h: add user_commands to struct.
4680 * main.c (define_command): Don't overload c->function with a char
4681 string as well as a function pointer.
4683 * eval.c (evaluate_subexp): Reinstall tiemann changes to
4684 calling convention of value_struct_elt () that got dropped in
4687 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
4688 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
4690 * tm-sparc.h (POP_FRAME): replace some constants with defines.
4692 * sparc-xdep.c (store_inferior_registers): defer stores to regs
4693 until a good time (e.g. when we are about to run the child),
4694 saving ptrace calls.
4695 * infrun.c (proceed): handle DO_DEFERRED_STORES.
4696 * tm-sparc.h: define DO_DEFERRED_STORES.
4698 * sparc-xdep.c (store_inferior_registers): when storing float
4699 registers, don't store stack regs too. When storing the SP,
4700 however, DO store the stack regs too. This fixes a bug in which
4701 the dummy frame is not recognized when a call_function finishes,
4702 because its frame pointer (in the stack regs) was never
4704 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
4705 even though we don't know how to read them from an inferior.
4706 valops.c (call_function): Comment about storing SP.
4708 * infrun.c (save_inferior_status): Save away the original bpstat
4709 chain so it can be restored later. Install the copied version for
4710 use by whoever saved the status. It will be blow away by
4711 restore_inferior_status, and the original chain restored. This is
4712 important for people who have pointers into the original.
4714 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
4715 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
4716 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
4719 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
4721 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
4722 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
4723 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
4725 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
4727 * Merge Mike Tiemann's multiple inheritance changes from Sun.
4728 Store the baseclasses in a type struct starting from array element
4729 0 rather than from the unusual array element 1.
4731 dbxread.c: the above.
4732 (virtual_context): Add
4733 Read new debug information about which virtual function table
4734 a virtual function is from, and store it in fn_field.fcontext.
4736 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
4737 TYPE_FN_FIELD_STATIC_P.
4739 symtab.c: the above.
4740 valops.c: the above. Handle pointer casts of object *'s.
4741 (search_struct_method): Add.
4742 (value_struct_elt): First arg is now a pointer to a value, and is
4745 valprint.c: the above.
4746 values.c (value_virtual_fn_field): Add type arg. Handle
4747 offsetting to the proper object when calling virtual fns.
4749 (baseclass_addr): Add valuep arg.
4751 * README: Document the current state of BFD config (missing).
4752 * TODO, ChangeLog, Makefile.dist: Roll version.
4753 * WHATS.NEW: Add summary of changes since 3.5.
4755 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
4757 * dbxread.c (read_struct_type): Clear bit vectors whenever
4759 symtab.c (B_CLRALL): define.
4761 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
4762 using == rather than =. Huh... This fixes the dreaded problem
4763 wherein builtin_type_int becomes TYPE_CODE_FLT.
4765 * core.c (info_files): Show the inferior pid.
4767 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
4768 already knows how to look in the source directory.
4770 * Remove psymtab hair from many places. Remove duplicated code
4771 for searching symbol tables. Hide psymtabs from most places.
4772 Make it fast to get from a psymtab to its symtab.
4774 blockframe.c (blockvector_for_pc): Remove psymtab hair.
4775 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4776 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4777 dbxread.c: export psymtab_to_symtab, make it work if called N times.
4778 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
4779 new symtab completely. New psymtabs get symtab pointer
4780 initialized to zero. Remove MI warning printf.
4781 symtab.h: Comments. Add psymtab to symtab pointer.
4782 (PSYMTAB_TO_SYMTAB): New macro.
4783 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
4784 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
4786 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
4788 (print_frame_info): Avoid special-casing symbols that have not yet
4791 * source.c (open_source_file): Quick path if we have already
4792 located the source file by its full name.
4794 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
4795 find_pc_psymtab. When a name is found in the misc function
4796 vector, search the symbol table for its mangled name, not the
4797 name that the user typed.
4799 * bfd.h: Fix missing comment terminators, make #endifs match.
4801 * valarith.c (value_less): Handle unsigned int comparisons.
4802 Add FIXME about pointer compares, which assume host and target
4803 pointers are the same.
4805 * command.c (do_nothing_command): lint
4806 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
4807 fix comments on debug symbol format for visibility. Actually set
4808 visibility of symbols.
4809 main.c (echo_command): lint; use <readline/history.h>.
4810 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
4811 obstack.h (_obstack_blank): Rearrange pointer math to avoid
4812 pointing past end of allocated memory; saber complains.
4813 obstack.h: Declare the external functions that we use.
4814 valarith.h: use <string.h>
4815 solib.c (solib_add): lint.
4817 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
4819 * main.c (initialize_main): Default info_verbose to off, now that
4820 symbol reading is fast.
4821 (quit_command): Avoid clobbering exec_bfd while quitting.
4823 * Initial BFD (binary file diddling library) merger:
4824 coffread.c: Change AOUTHDR to struct exe_hdr.
4826 core.c: initialize initialized data at compile time.
4827 (core_file_command): Move from coredep.c, convert to bfd.
4828 (xfer_core_file): Convert to bfd.
4829 exec.c (exec_file_command): use bfd routines.
4831 mips-tdep.c: Remove exec_file_command and friends.
4834 * coredep.c: (fetch_core_registers) Convert core_file_command to
4835 fetch_core_registers.
4836 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
4838 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
4839 (my_bfd_read): More bogosity, which I don't think we call.
4840 (program_name): Remove this atrocity asap!
4842 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
4845 values.c: allocate_repeat_value was not clearing the
4846 optimized_out field.
4847 (value_static_field): minor stylistic fix (wrong macro was used).
4848 valops.c (value_struct_elt_for_address): didn't work for C++
4851 * signame.c (_initialize_signame): Initialize signal names once.
4853 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
4854 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
4855 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
4857 * remote-eb.c: Support user-settable baud rates on the serial port.
4859 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
4861 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
4863 * tconfig/sun3os4: Remove warning about native assembler,
4864 since it also occurs in the xconfig file.
4866 * findvar.c (registers): Allocate some slop after `registers'
4867 to prevent stray accesses from trashing the next variable.
4869 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
4870 on the sun-3, by changing the #ifdef from `sun3' (which is not
4871 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
4872 vars, which happened to follow `registers' in the executable.
4874 * readline/history.c (history_search): Heed gcc-2's advice
4875 and parenthesize && inside ||).
4877 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
4878 tm-29k.c: Insert FSF copyright headers.
4880 * remote-eb.c: Better comments.
4882 * Makefile.dist: Update to 3.91.6.
4883 * TODO: note PREPARE_TO_STORE problem.
4885 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
4887 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
4889 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
4891 * infrun.c (wait_for_inferior, at end): Don't set up
4892 prev_* if the inferior no longer exists.
4894 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
4895 CANNOT_EXECUTE_STACK.
4896 valops.c (call_function): Use it.
4898 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
4900 * inferior.h (PC_IN_CALL_DUMMY): New macro.
4901 infrun.c (wait_for_inferior, 2 places): Use it.
4903 * values.c (value_being_returned): Only use
4904 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
4906 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
4907 right thing for remote-eb.c.
4909 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
4910 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
4912 * blockframe.c: Put get_frame_saved_regs inside #if !defined
4913 (FRAME_FIND_SAVED_REGS).
4915 * findvar.c ({fetch,store}_registers): Check for
4916 REMOTE_{FETCH_STORE}_REGISTER macro.
4918 * findvar.c (get_saved_register): Add argument lval and
4919 change meaning of argument addr.
4920 findvar.c: Change calls to get_saved_register to reflect
4921 new calling convention.
4922 valops.c (value_assign): Use get_saved_register instead of
4923 find_saved_register.
4925 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4927 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
4928 an (uninitialized) pointer to one. Use "&" when passing it
4931 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4933 * coffread.c (getfilename): Use DGUX x_offset and x_name if
4936 * coffread.c (symbol_file_command): Put semicolon after
4938 Put safe_to_init_tdesc_context in #if defined (TDESC).
4939 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
4940 coffread.c: #include <sys/stat.h>.
4941 (read_coff_symtab): Typo: in_source_files -> in_source_file.
4942 Add missing ')' in check for "lc%" and friends. Remove
4944 Declare read_one_sym() at top of file.
4945 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
4946 MC68WRMAGIC can have the same value without causing a duplicate
4949 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
4951 * Allow a Makefile to be built without building the
4952 tm and xm file links that screw up builds in subdirectories.
4953 This is done with `config.gdb none', then you can do things
4954 like `make gdb.tar.Z'.
4955 * tconfig/none: Config file for no target system
4956 * xconfig/none: Config file for no host system
4957 * config.gdb: If no TM or XM files are called out by the
4958 host or target file, don't make links for them.
4960 * cplus-dem.c: Add documentation.
4962 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
4963 simple error, so the user's gdb doesn't crash due to some object
4964 file problem (e.g. somebody is rebuilding the file out from under
4967 * printcmd.c (print_address_symbolic): demangle the symbol.
4969 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
4970 Motorola copyrights in it. Make "make gdb.tar.Z" work.
4971 (alldeps.mak): sort and uniq all results from this; duplicates
4972 hose gdb.tar.Z link building. Remove RCS files from
4973 tconfig and xconfig. Add config files for sun386. Add
4974 a few odd files to OTHERS and HFILES.
4976 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
4978 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
4979 Roll version number to 3.91.5. Make lint work in bindir.
4981 * README: Document cross-debugging and new file structure.
4983 * blockframe.c: Lint. Include "value.h" to declare read_register.
4984 (find_pc_partial_function): remove duplicate line.
4986 * command.h: Lint. Declare error_no_arg and dont_repeat.
4988 * tm-news.h: Remove inadvertently duplicated stuff.
4990 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
4991 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
4993 * config.gdb: Allow `config.gdb host target' form. Clean
4994 up previous change that printed bogus messages when you just said
4997 * core.c: #include "command.h" for lint.
5000 * main.c: Remove some casts of enums. Lint.
5007 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5009 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5010 read it from memory. This will allow us to save ptrace calls
5011 eventually. Changed caller single_step too.
5013 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5014 that we aren't going to use, saving many ptrace calls, especially
5015 when watchpointing or single stepping. Use some #define's for
5017 (store_inferior_registers): Ditto.
5018 (core_file_command): Use some #define's for constants.
5020 * tm-sparc.h: Add #define's for some register numbers, so we
5021 can eliminate the use of random constants in sparc-xdep.c.
5023 * stack.c (frame_command, print_frame_info, up_command,
5024 down_command) Remove frame_changed, since it
5025 causes a bug and doesn't seem to do anything useful. In some
5026 places it was used as a flag, in others as a stack level (?).
5028 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5029 default is to use the portable (vprintf) version rather than the
5031 * xm-news.h (MISSING_VPRINTF): Add.
5033 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5035 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5037 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5038 about linking debugged programs -Bstatic in the sun?os4 config
5039 files in tconfig and xconfig subdirectories.
5041 * main.c (main): Remove unreached exit(0) now that we exit
5044 * Create TODO file for online bug list. There are too many
5045 "little" bugs to keep track of on paper.
5047 * Change Projects file to refer to bug-gdb@cygnus.com
5048 rather than kingdon@ai.
5050 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5052 * Makefile.dist (VERSION): 3.91.4 now.
5054 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5055 (condense_misc_bunches): Add sanity check that misc_count is
5056 the same as the number of symbols in the bunch.
5058 * coffread.c: rename init_misc_bunches. Pass an argument
5059 to condense_misc_bunches (a zero).
5061 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5062 every time we are called; don't rely on our caller to do it.
5063 (add_file): Remove call to init_misc_bunches.
5065 * mipsread.c: Only warn, don't error, if unknown symbol types.
5066 This keeps an old gdb from falling on its face if it sees newly
5067 extended symbol info. Rename init_misc_bunches.
5069 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5071 * Merge in changes from Per Bothner for DECstations and other
5072 MIPS stuff. The rest is Bothner speaking:
5074 The next message is a merger of Alessando Forin's mips port with
5075 mine. I've tried to use my good if biased judgment to get
5076 the best of both. It *does* need testing.
5078 Some of the changes are general, *not* mips-specific.
5081 Didn't believe in little-endian bit order.
5082 There are still inconsistencies about whether flags
5083 like BITS_BIG_ENDIAN are integer (#if ...) or
5084 boolean (#ifdef ...). I tried to paper over them.
5086 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5087 Moved some misc_function code that was common to
5088 {dbx,coff,mips}read.c to symtab.c.
5089 In the process, I think I cleaned things up a bit.
5090 At the same time, moved obsavestring and obconcat to symtab.c.
5093 Removed obsolete condense_addl_misc_bunches (use
5094 condense_misc_bunches(1) instead).
5097 Needed to include <sys/dir>, at least on DECstations.
5099 valops.c, mips-tdep.c, tm-mips.h:
5100 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5101 conventions (when STACK_ALIGN is insufficient).
5102 Needed on mips, where doubles need 8-byte alignment,
5103 but ints only need 4.
5106 Removed cruft that was not being used.
5107 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5110 Print $ before register-names (I think that makes things a little
5112 Never print two instructions, even if one delays.
5113 Removed hex-disassemble set_cmd. (This is not mips-specific,
5114 so I think the argument is whether it is generally worthwhile or not.
5115 I'm inclined to think not, given how easy it is to
5116 convert between radixes in gdb.)
5119 This is basically Alessando's code.
5120 It doesn't use obstacks; I changed it to use obstacks
5121 in a few minor places where using malloc causes a
5122 memory leak. (Probably, more places could/should be changed.)
5123 I added record_misc_function where it was missing.
5124 In symbol_file_command and add_file_command, I tried
5125 to make the code consistent with more recent versions.
5126 Minor sylistic changes in parse_procedure.
5127 Make a .gdbinfo. psuedo-symbol point back to the real
5128 procedure symbol (using the isym field).
5131 This is basically from my port, but with a lot of details
5132 and a number of routines merged in from Alessando's version.
5133 I basically used my code "raw" backtrace (use heuristics
5134 from the actual code, rather than symbol table info) - though
5135 the idea is Alessandro's. I feel my code is a little cleaner
5136 here, particularly in being a little more flexible, such as being
5137 able to handle gcc-produced code (which it now can).
5138 It also doesn't do frame caching (which is not useful
5139 more recent gdb versions).
5140 I also used my code for push_/pop_dummy, more or less.
5141 I tried to incorporate AF's code for testing sigtramp
5142 while backtracing; I probably got it wrong.
5143 Added mips_print_register, which tries to scrunch as much
5144 information as possible on a screen...
5145 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5146 under mips-pinsn.c), I don't see anything mips-specific here,
5147 and I don't see it being all that useful anyway.
5150 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5151 Use more register names (rather than hard-cases numbers).
5153 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5155 * Hack up 3.90.11 changes:
5157 * Makefile.dist (depend): parameterize $(GCC).
5158 Add solib.c and solib.o.
5159 (readline): Fix vpath for both absolute or relative SRCDIR.
5161 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5162 Also, let the part I didn't understand at least compile so
5163 I can test the rest. FIXME.
5165 * dbxread.c: Fix thinko using strcmp.
5166 (init_psymbol_list): declare static.
5167 (partial_symbol_file_open): Comment cleanups better, avoid
5168 cleaning up the string table since the caller will do that.
5169 Move the stat for mod time into symbol_file_command, temporarily.
5170 (There should be a mod time for each symbol file, eventually,
5171 to control its rereading. FIXME.)
5173 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5174 SunOS, which gives error for shared libs otherwise. (From
5175 Schaefer, probably FIXME needs work for portability.)
5177 * solib.c: Move #include "param.h" to work.
5178 Lowercase all the Uppercase Letters In the Messages.
5179 (find_solib): Clean up inferior_so_name for debug printouts.
5180 Allow no argument, to mean all shared libraries.
5182 * symmisc.c: include param.h to get CLEAR_SOLIB.
5184 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5186 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5187 to 3.90.11. ChangeLog entries below are from this.
5189 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5193 * Makefile.dist (HFILES): Add tm-sunos.h.
5195 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5199 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5201 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5203 * sparc-opcode.h Added single-operand version of rett.
5205 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5207 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5208 Put parens around gcc_p in expansion.
5210 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5212 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5214 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5216 * Changes for Sun shared libraries:
5217 blockframe.c (find_pc_partial_function): If a non-text symbol
5218 is found, set *address = pc - FUNCTION_START_OFFSET.
5219 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5220 Disable breakpoints instead of giving an error.
5221 source.c (select_source_symtab): Initialize cs_pst.
5222 symmisc.c: Call CLEAR_SOLIB if defined.
5223 symtab.h: Make text{low,high} CORE_ADDR not int.
5224 (psymtab): New field addr.
5226 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5227 (record_misc_function): Give correct type for N_DATA symbols.
5228 (condense_misc_bunches): do "misc_function_count = j" regardless
5230 Take code which is shared between symbol_file_command and
5231 add_file_command and put it into partial_symbol_file_{open,read}.
5232 Split add_file_command into add_file_command and add_file.
5233 Make psymtab_to_symtab read in the string table if the file
5235 Two new parameters to read_dbx_symtab and start_psymtab.
5236 tm-sunos.h: New file.
5238 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5240 * infcmd.c: Change cont_command to continue_command and "cont"
5243 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5245 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5247 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5249 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5250 size 1,2,4,8 rather than size < 8.
5252 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5253 as necessary, not just once.
5255 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5257 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5259 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5261 * tm-news.h: Add CALL_DUMMY_*.
5263 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5265 * config.gdb: In list_host, list_target, use ${i}, not $i.
5267 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5269 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5271 * sparc-opcode.h: Change all store floating-point state register
5272 instructions to have the right match & lose fields.
5274 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5276 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5278 config.gdb: If srcdir != ., create readline directory and
5279 copy a makefile into it.
5281 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5282 consistency with POSIX.
5284 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5285 when we exit its exp_valid_block.
5287 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5289 * Makefile.dist: Bump version to 3.91.3.
5291 * Clean up handling of breakpoint commands (somewhat).
5292 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5294 inferior.h: Add breakpoint_proceeded to inferior status struct
5295 and globals; save it and restore it.
5296 (clear_breakpoint_commands): Cleanup, remove old #define.
5298 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5299 (save_inferior_status, restore_inferior_status): handle it also.
5300 (proceed): Remove earlier code that set breakpoint_proceeded.
5301 It is now set only in clear_proceed_status.
5302 (clear_proceed_status): Cleanup, use bpstat_clear rather
5303 than clear_breakpoint_commands. No callers need the stop_bpstat
5304 between clear_proceed_status and proceed.
5306 infcmd.c: Add breakpoint_proceeded definition and comment.
5307 (cont_command, jump_command, signal_command): Move call to
5308 clear_proceed_status right next to call to proceed.
5310 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5311 caller's argument while running down the chain of breakpoints.
5312 Use new variable "breakpoint_proceeded" to determine when
5313 a command that it executes moves the inferior past the
5315 (bpstat_clear): Handle NULL argument.
5316 (bpstat_clear_actions): Avoid useless call to
5317 breakpoint_auto_delete.
5318 (delete_breakpoint): Clean up bpstat's that are pointing to
5319 the deleted breakpoint from the stop_bpstat chain.
5320 (breakpoint_auto_delete): Simplify.
5322 * Clean up handling of EOF, error on stdin, etc. This was
5323 prompted by a network problem that caused gdb to go into an
5324 infinite loop filling up its malloc'd memory.
5326 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5327 not clear_breakpoints_commands, which is now gone.
5328 (main): If command_loop returns (e.g. from EOF on stdin), do
5329 a quit_command (looping back to command_loop if quit_command
5330 doesn't really quit).
5331 (command_loop): check result from command_line_input and
5332 exit if it returns NULL, rather than passing the NULL to
5334 (gdb_readline): Free malloc'd result space before returning
5337 * utils.c (query): Handle C-d to mean "yes", just as if the
5338 input was not a terminal. Also avoid infinite loop if EOF
5339 occurs in mid-input-line before newline. This allows
5340 query to be used at EOF on stdin with reasonable results.
5342 * infrun.c (proceed): Set breakpoint_proceeded.
5344 * values.c (value_as_long): Avoid infinite recursion for enums.
5345 (_initialize_values): Fix typo in help msg (kingdon).
5347 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5348 RL_LIB for linking. This allows -lreadline for linking
5349 and nothing for dependencies, once readline is a real library.
5351 * config.gdb: Jim Kingdon: give useful error message if the
5352 host or target type is not recognized.
5354 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5355 it just defines it. Dumb, but deal with it.
5357 * Jim Kingdon suggests:
5358 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5360 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5362 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5364 * Clean up Bothner's changes.
5366 * blockframe.c (clear_pc_function_cache): New function.
5367 * blockframe.c: remake cache_pc_function_* static.
5368 * dbxread.c (symbol_file_command): remove references to
5369 cache_pc_function_* variables.
5370 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5371 * printcmd.c: Avoid kludging a global variable (addressprint)
5372 to avoid printing the address of a string twice. Instead,
5373 pass the format letter 's' down low enough that it can be seen
5374 to avoid this problem.
5375 (print_formatted): Pass format arg to value_print.
5376 (restore_addressprint): Remove function.
5377 (do_examine): Avoid hacking addressprint, cleanups and such.
5378 (print_frame_args): Add a comment to a Bothner change.
5379 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5380 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5381 to wipe out the values cached in blockframe.c.
5382 * symtab.c (find_method): Add comment saying how big you must
5383 allocate to be "big enough". Per being terse again.
5384 * valprint.c (val_print): Handle format letter "s" to print
5385 strings without addresses. Add comment to vtbl printing code
5386 which casts with wild abandon. Rearrange reference-printing
5388 @0xaddr: value (print w/addressprint)
5389 value (print w/~addressprint)
5390 @0xaddr (parameter lists w/addressprint)
5391 or nothing (parameter lists w/o addressprint)
5393 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5395 * Merge more changes from Per Bothner:
5397 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5398 annoying) that I tried to improve it. Here are my suggestions.
5400 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5403 Do automatic de-reference when taking the address of a reference.
5405 Don't deref_ref when printing parameter lists.
5407 More attempts at treating refernences properly.
5409 In val_print, if deref_ref==0, don't print dangling " = ".
5411 Add COERCE_REF macro, which de-references an REF.
5413 * Merge changes from Per Bothner:
5415 * Fixed (Sony news)-specific configuration problems.
5416 * Fixed other problems with using vanilla pcc and libc (enum problems;
5417 assumption that vsprintf exists).
5418 * Some major speed-ups (finc_pc_partial_function now caches a match;
5419 parsing avoids duplicate symbol_lookup calls).
5420 * Changed handling of baseclasses (no longer use baseclasses field
5421 of struct type, use the first n_baseclasses fields instead).
5422 * Various minor changes/fixes, most C++-related.
5425 Cache the most previous match from find_pc_partial_function.
5426 (Save both low and high ends of matching function's pc range.)
5427 This speeds up the loop of infrun.c:wait_for_inferior quite
5428 a bit, and makes step/next commands much zippier.
5430 Added an enum->int cast (otherwise, some compilers barf).
5432 No longer set baseclass offset to 0, since multiple
5433 inheritance now mostly works.
5434 Added a number of casts, to shut up compiler warnings
5435 (after stabs where made enums, not ints).
5436 When discarding a symbol table (in symbol_file_command),
5437 must clear the cache introduced in blockframe.c.
5438 Don't convert $vtbl_ptr_type to vtbl any more.
5439 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5440 Mask off sign bit emitted by g++ for virtual table offset.
5441 Set voffset to -1 (not 1) for static member functions.
5443 Changed parsing/lexing of names to avoid doing symbol lookup twice
5444 (once when lexing to determine symbol class, once for real).
5445 Now only call symbol_lookup once. Fields of 'this' win especially big.
5447 Subpress printing addr twice in the case of 'x/s addr'.
5449 lookup_basetype_type is no longer used.
5450 Add find_methods as recursive helper function to decode_line_1.
5451 This allows multiple inheritance to work.
5452 Also, once one or more matches has been found, do not look in
5453 base-classes. (Baseclass methods would be overridden, anyway.)
5455 Removed baseclasses array in struct type.
5456 Instead of using baseclasses[i], use fields[i-1].
5457 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5458 Changed sign convention of voffset (previous was inconsistent).
5460 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5462 Used to assume existence of vsprintf. Re-written to not need it
5463 if HAVE_VPRINTF is undefined.
5465 typecmp was too pessimistic. Made it less so.
5467 Don't print space after address.
5468 If vtable points to a misc symbol (with 0 offset), print it,
5469 since that indicates the actual class of the object.
5470 Changed ype_print_derivation_info to use new inheritance
5471 scheme (without baseclasses vector).
5473 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5474 Also, changes needed because TYPE_BASECLASSES were removed.
5476 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5478 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5481 If there is no path set, and the symbols don't indicate what directory
5482 a file was compiled in, look in the current directory. But either
5483 a path or a known compilation directory will prevent this.
5486 Three independent bug fixes:
5487 * Remove the #if 0 block that breaks some stuff.
5488 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5489 adapt gdb to either SunOS 4.0.* or 4.1.
5490 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5493 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5496 (type_print) Demangle the name being printed.
5497 (type_print_base) Handle botched demangling without coredump (tiemann).
5500 (check_stub_method): Document routine.
5501 (tiemann) fix bug for no-arg functions
5502 Avoid clobbering beyond end of malloc'd storage.
5503 Terminate the argument list properly.
5505 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5507 * Changes merged by John Gilmore:
5510 In breakpoint_1, use new print_address_symbolic instead
5511 of find_pc_partial_function. (This forces use of assembler-level
5512 addresses, and avoids misleading non-mangled source-level names.)
5514 Generalize ansi argument such that -1 means skip arglist totally.
5515 Removed global variable print_ansi_qualifiers (which made
5516 code non-reentrant), in favor of extra explicit arguments
5517 to internal routines.
5519 Add new helper function print_address_symbolic.
5520 Use find_pc_misc_function instead of find_pc_partial_function
5521 (since we want assembler-level symbols here).
5523 Print unknown function as just "f (...)", not "f (...) (...)".
5524 Use new fputs_demangled explicitly.
5526 Fixed a typing violation (problem: value.h cannot be imported
5527 without renaming many variable in this file).
5528 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5529 decode_line_1: Moved forward some never-reached code.
5530 Made decode_line_2 skip function prologues correctly.
5532 fputs_filtered should not demangle by default.
5533 Add new fputs_demangled to demangle on demand..
5535 Change value_struct_elt to use value_primitive_field (using recursive
5536 utility function search_struct_field). This allows foo.bar to work
5537 for multiple inheritance (so far only for data fields).
5538 Change check_field in the same way (recursive helper function
5539 to support multiple inheritance).
5540 (Note: there are more of these problems that I haven't fixed.
5541 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5542 value_of_this: 'this' symbol name is now just "this", note "$this".
5544 Don't print static members.
5545 Avoid printing "members of <type>" if there are none.
5546 Simplified type_print_derivation_info by merging duplicate code.
5547 Remove useless blank lines in type_print_base (ptype command).
5549 Added declaration of new routine value_primitive_field.
5551 Added value_primitive_field which is generalized version of
5552 value_field that can handle multiple inheritance (non-zero offsets etc).
5553 Re-implemented value_field to call value_primitive_field.
5555 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
5557 * infcmd.c -- insert else to avoid 'delete env' coredump when you
5558 delete the whole environment. Karl Berry reported the bug.
5559 * source.c - fix openp to avoid //'s in filenames, which
5560 trigger an Emacs bug causing it to not be able to find files
5561 when running gdb in a window.
5562 * dbxread.c - zap the #if 0 that botches the add-file code.
5563 It seems to work a lot better without all the code commented out.
5565 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
5567 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
5570 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
5572 * Makefile - added a ${CFLAGS} to a couple of entries,
5573 added remote-sa.sparc.c
5574 * added remote.sa-sparc.c, a modification of remote.c
5575 which conducts a dialog directly with the SparcStation prom.
5576 * breakpoint.c, infrun.c, sparcdep.c added
5577 remote_insert_breakpoint(), and remote_remove_breakpoint()
5578 to breakpoint.c instead of directly writing breakpoint instructions.
5579 * sparcdep.c on remote_debugging,there is no need
5580 to remove signle step breakpoint instructions.
5581 * main.c added "-epoch" flag and "int epoch_interface" to main.c
5583 * printcmd.c - epoch interface sends lisp expressions to open up
5584 epoch windows on inspection.
5585 * valprint.c - added arrayprint, and addressprint and made adding
5586 format controls easier
5587 * wait.h added a couple of undef's because we were getting
5588 complaints about WSTOPSIG and WTERMSIG begin redefined.

5616 should print ANSI qualifiers (such as `const' and `volatile').
5617 All callers changed to call with ANSI == 1, except from
5618 `check_method_stub', which uses old-style syntax.

5658 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
5659 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
5660 when printing the type.
5662 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)

5684 step_resume_break_address != NULL, even if another_trap.
5685 If trap_expected and we enter sigtramp, then set up a
5687 If trap_expected is set when we hit the step_resume_break,
