1 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)
3 * doc/gdb.texinfo: Catch up to changes recorded here in ChangeLog
4 (nodes Continuing and Stepping; Memory; Targets) clarifications
7 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
9 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move
10 REGISTER_U_ADDR to corresponding xm- file. Sugg. by Peter Schauer.
12 * symmisc.c (print_partial_symtabs): Add printpsyms debug cmd.
14 * m68k-tdep.c (m68k_push_dummy_frame, m68k_pop_frame): Add
15 generic routines for calling inferior functions.
17 * blockframe.c (inside_main_scope, inside_entry_scope): New.
19 * copying.awk: Filter formfeeds out of copying & warrantee.
20 Make them available as `show copying' and `show warrantee' also.
21 * main.c (print_gnu_advertisement): Advt `show' commands.
23 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)
25 * mach386-xdep.c: Even when cross-compiling, leave in the
26 core-file reading code.
27 * core.c (get_core_registers): Avoid coredump if no .reg section.
29 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
31 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
32 This avoids coredumps under `set print object on' in value_headof
33 (called erroneously by value_from_vtable_info) for `p &struct'
34 or `p *struct'. From Peter Schauer.
36 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
38 * Makefile.in: Roll version to 4.1.2.
39 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
40 size from BFD (but, FIXME, we don't yet read external nlists's and
41 convert them to internal nlists's before handling them -- we still
42 assume they have the same size and alignment.) Use SET_NAMESTRING
44 * exec.c (exec_file_command): Move dead coff-encapsulation code
46 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.
48 Fri Oct 4 22:30:06 1991 John Gilmore (gnu at cygnus.com)
50 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
51 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
53 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
55 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
56 * mips-xdep.c (store_inferior_registers): Don't try to
57 write the (pseudo) FP.
58 * mipsread.c (parse_partial_symbols): Improved algorithm for
59 setting pst->texthigh.
61 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
63 * doc/Makefile: make TEXINPUTS include . everywhere
65 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
67 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
68 vestiges of typevectors, which were for symsegs and are no longer
69 used. (From a question by Eliot Dresselhaus
70 <dresselh@RFT30.nas.nasa.gov>).
72 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
74 * dbxread.c, coffread.c: static-ize functions that were
75 gratuitiously external. (From Fred Fish.)
77 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
79 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
80 until it is large enough.
82 * dbxread.c (read_type): Handle error case slightly better.
83 Make complaint message not C++-specific.
85 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
87 * infrun.c (wait_for_inferior): Fix step/next so that you only
88 stop at the beginning of a new line. This fixes various problems
89 with for loops, nested if-else's and switch statements.
91 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
93 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
94 between symtabs and psymtabs become ordinary error()s.
96 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
97 properly, making "end pc" correct in shared lib psymtabs.
98 (From Guy Harris <guy@auspex.com>.)
100 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
102 * dbxread.c: Enable, but soften, const_vol_complaint.
103 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
104 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
105 should be file-scope, not global.
106 (read_struct_type): Remove ancient multiple-inheritance warning.
107 (read_range_type): Check base type, complain & patch if undefined.
108 * stack.c (frame_info): Demangle the function name in `info stack'.
111 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
113 * eval.c (evaluate_subexp_for_address): Don't use
114 TYPE_POINTER_TYPE directly (it might be zero if this type has
115 never had a pointer created before); use lookup_pointer_type.
116 * symtab.c (lookup_method_type): Arguments were swapped in all
117 callers, so fix it here. I'm amazed this worked at all!
119 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
121 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
122 "bss" rather than "data" symbols, but which still conflict.
125 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
126 * core.c (core_files_info): Shorten output.
127 * exec.c (exec_files_info): Ditto.
128 (build_section_table): Ignore zero-length sections.
129 * language.c, printcmd.c: Lint.
130 * language.h (get_frame_language): Declare.
131 * saber.suppress: update.
132 * stack.c (find_relative_frame): Remove complex code that was
133 #if 0'd, stick with simple code. Lint.
134 * saber.suppress: Update a bit.
135 * symfile.c (add_symbol_file_command): Add "?" to question.
136 * utils.c (parse_escape): Avoid \a due to bdead compilers.
137 * value.h: Declare typedef_print.
139 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
142 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
143 (Reported by Mark Peek <mark@imagen.com>.)
145 * solib.c (solib_map_sections): Relocate all sections, even
146 though only the text section's size is tracked. Mark ld_text
147 for eventual elimination as we generalize to N sections.
149 * infrun.c (wait_for_inferior): Don't check if the PC is in a
150 call_dummy if we were stopped by a random signal that is being
151 passed to the program. This produced wierd results when calling
152 functions in the inferior and signals (e.g. SIGALRM) were in use.
154 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
156 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
157 Bugfix from Paul Eggert <eggert@twinsun.com>.
158 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
159 * valprint.c (print_floating): Print 9 digits for IEEE floats.
162 Mon Sep 23 15:50:07 1991 John Gilmore (gnu at cygnus.com)
164 * Makefile.in: Roll VERSION to 4.1.1.

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

294 code for saving types of parameters with each function definition.
295 * dbxread.c (define_symbol, function and parameter cases): Ditto.
296 (read_dbx_symtab, case N_DEFD): Ignore.
297 (read_enum_type): Recognize FALSE/TRUE enum as Modula-2 BOOLEAN.
298 (read_range_type): Rename MAX_OF_TYPE to MAX_OF_C_TYPE, etc.
299 #if 0 out its uses, though, since they set a dead value.
300 * coffread.c (end_symtab): Use allocate_symtab.
301 (process_coff_symbol): #if 0'd for functions and params as above.
302 (read_enum_type): Recognize Modula-2 BOOLEAN.
303 * symtab.c (add_param_to_type): #if 0'd function to add a
304 parameter type to a function type's field list.

375 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
377 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
378 entries are enclosed herein. Not all of these changes
379 have been merged into the master GDB sources -- check the
380 ChangeLog above here for the merge log.
382 Mon Jun 3 17:05:45 EDT 1991
384 m2-exp.y Created. Tested outside of GDB for a few days. Proper
385 operators were added, C specific operators and tokens
386 removed. yylex() revamped to some extent. Still things
387 missing from the grammar, such as sets.
388 Tested for two weeks in GDB v3.5.
390 Tue Jun 11 17:23:48 EDT 1991
392 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
393 so they are built-in. Sort of a hack.
395 Fri Jun 14 12:53:51 EDT 1991
397 m2-exp.y Added range checking for numeric constants. Any numeric
398 constant is assumed to be of builtin type INTEGER unless:
399 (1) it is octal or hexadecimal, in which case it is a
400 CARDINAL; (2) it is too big to fit into an INTEGER, in
401 which case it is a CARDINAL.
402 eval.c Added simple range checking for +, -, and * on integers.
403 Doesn't work very well for *, since 6 * 1,000,000,000 =
404 1,705,032,704, which fails the simple test of result >=
405 first_operand, no matter in what order the operands are.
407 Tue Jun 18 14:11:30 EDT 1991
409 Broke the parser into parts, one containing the C grammar and the other
410 containing code to be shared by all of the grammars.
412 The following files no longer exist:
417 The following files were added:
419 c-exp.y (The C grammar)
420 m2-exp.y (The Modula-2 grammar)
421 parser-code.c (Code that is shared by the above grammar)
425 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
426 now necessary to use the Bison compiler compiler, since it
427 will generate function/variable prefixes other than yy.
429 Tue Jun 18 16:47:49 EDT 1991
431 symtab.[ch] Added the external variable working_lang, than holds the
432 value of the current working language.
433 Added the ennumerated type language_mode, with the values
434 language_auto and language_manual, the former meaning that
435 GDB sets working_lang as needed, and the latter meaning
436 that the value of working_lang is totally under user
438 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
439 REAL, BOOLEAN and CHAR. Also added the type codes
440 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
441 utils.c Added set_language_command and show_language_command to
442 implement the GDB support commands "set language" and
444 expression.h A number of identifiers were added to the type exp_opcode
445 to facilitate Modula-2 builtin functions, integer
446 division, and array indexing.
448 Wed Jun 19 13:25:58 EDT 1991
450 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
451 if the language specified by working_lang requires the use
452 of strict typing of expressions. Eventually, even this
453 will be able to be changed by the user.
454 Added the macro RANGE_CHECK, which evaluates to non-zero
455 if the language specified by working_lang requires the
456 checking of a value against the domain of its type.
457 Eventually, even this will be able to be changed by the
459 language.[ch] Predicates involving types (simple_type, ordered_type,
460 same_type, integral_type, numeric_type, character_type,
461 boolean_type, float_type) are added. These predicates are
462 based on the current value of working_lang, and are handy
465 Wed Jun 19 15:39:34 EDT 1991
467 eval.c Added the function type_array_rank which computes the rank
469 valarith.c Added the funtion value_bool, which when given a integer
470 value.h value (ie. struct value *) as an argument, it returns a
471 boolean value (ie. struct value *) true if that integer
472 is non-zero, and a boolean value false otherwise.
473 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
474 will print out properly.
476 Wed Jun 19 16:36:34 EDT 1991
478 valops.c Added the function value_capitalize, which returns it
479 value.h argument capitalized if its argument is a lowercase
480 letter, or the argument unchanged if its argument is not a
482 valarith.c Added the function range_check_p, which returns non-zero
483 value.h if its value argument is between the integral bounds upper
485 Added the function range_check_enum_p, which makes sure
486 that its value argument is a valid member of the domain of
488 Added the function range_check_range_p, which makes sure
489 its value argument lies between the upper and lower bounds
490 of its type argument, which must be a ranged type.
491 Added the function check_array_index, which range and type
492 checks an index of an array.
493 Added the function value_multi_subscript, which computes
494 array[idx1,idx2...idxN], given a value array and an array
495 of values representing indicies.
496 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
497 unpack_long to work with TYPE_CODE_BOOL and
500 Wed Jun 19 18:04:08 EDT 1991
502 symtab.c Stored pervasive types in a structure and make
503 lookup_pervasive_type() a lookup function that was based
504 on working_lang. If lookup_pervasive_type() returned
505 non-zero, then that value was returned (a fix, since
506 before it simply wouldn't return the pervasive type.)
507 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
508 non-zero if the language specified by working_lang means
509 "conversion" when it says "cast".
510 valops.c Added the function value_real_cast(), which performs a
511 value.h *cast*, not a *conversion*, which is what value_cast()
512 does when it can. In particular,
513 value_cast(<float_type>,4) = 4.0, while
514 value_real_cast(<float_type>,4) = some mess.
515 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
516 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
517 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
518 and MIN on integral types. *NOTE*: These are currently
519 hardcoded to work only if there are 8 bits per storage
521 eval.c Made logical functions call value_bool to return a
522 properly typed boolean value, based on working_lang.
524 Thu Jun 20 11:55:27 EDT 1991
526 valprint.c Types now print out in a Modula-2 fashion. This works for
527 the cases when the type is printed out step-by-step, that
528 is, it doesn't work when the name of a structured type
529 (which includes the keyword "struct", etc.) is simply
531 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
532 since type specifications in C and Modula-2 are very
533 different. The C printing of a type is very recursive,
534 whereas in Modula-2 it is generally very simple. C has
535 type prefixes and suffixes, which have no real analogue in
536 Modula-2. Maybe type_print() should call a language
537 specific type printer. This is also advantageous if we
538 compile GDB to exclude some of the languages. We'll just
539 leave those functions out.
541 Thu Jun 20 16:57:10 EDT 1991
543 dbxread.c When reading the complete symbol table in (via
544 psymtab_to_symtab()), the number and types of function
545 arguments are added to a function type. define_symbol()
546 calls add_param_to_type() to accomplish this.
547 Assumption: when we come across a function definition
548 (N_FUN symbol with an 'f' or 'F' in the name), its
549 arguments will appear before another function definition.
550 When a function is found, a pointer to its type is placed
551 in the global in_function_type. Changes that
552 add_param_to_type() makes are to this global.
553 valprint.c The type of a function now includes (for Modula-2) the
554 types of its parameters.
555 eval.c Type checking and a check for the proper number of
556 arguments is now done for function calls. Not sure of the
557 impact this has on C++ member function yet.
559 Thu Jun 20 19:58:48 EDT 1991
561 valprint.c Rewrote the type printer. Broke it into two language
562 specific parts, adding the functions type_print_m2() and
564 An unfortunate consequence is this: if you debugging a C
565 program in Modula-2 mode (why?), info types does not work
566 well with regular expressions, since the types are printed
567 out in Modula-2 terminology, but stored in C terminology.
568 language.[ch] Added the functions new_type_last(), type_keyword(), and
569 type_sep() to aid in the printing of typedefs.
570 symtab.c Made the printing of typedefs as language independent as
571 possible through calls to new_type_last(), type_keyword(),
574 Fri Jun 21 11:50:26 EDT 1991
576 dbxread.c Check all incoming ennumerated types. If it looks like
577 Modula-2's BOOLEAN type, then change the type_code of the
578 type to TYPE_CODE_BOOL so we can process it as a boolean
580 valprint.c Replaced some of the 0x%x with calls to sprintf and
581 hexformat() in val_print().
582 language.[ch] Added the function hex_to_string(), which converts its
583 integral argument to a hexadecimal number (format is
584 language based) and returns the result as a string.
586 Mon Jun 24 12:25:07 EDT 1991
588 valprint.c Some functions call type_print_1() directly, instead of
589 value.h using type_print(), so they can specify where (column) to
590 print things. Since type_print() takes care of language
591 dependence, that needs to be called first. Added a
592 parameter depth to type_print() (so it is now like
593 type_print_1). Changed type_print to type_print_at, and
594 made type_print a macro that passes a depth argument of
596 symmisc.c Changed all calls to type_print_1 to calls to
598 Makefile.dist Made it possible to build GDB for a specific set of
599 depend languages. Do this by passing a definition for the macro
600 LANGS to make. LANGS should be a string containing a
601 space-separated list of language names (ie. LANGS="c m2").
602 The default is to build all languages. Note that grammar
603 files must follow the naming convention of <lang>-exp.y.
604 gdb.lang This holds the current value of the LANGS macro. It is
605 examined every time make is called, and is updated if
607 eval.c Added #ifdef _LANG_<lang> to these files.
608 expread.c Still need to add them to dbxread.c and coffread.c.
616 Mon Jun 24 16:33:11 EDT 1991
618 language.[ch] Added the functions hexformat_pre() and
619 hex_to_string_pre(), which take a prefix argument to
620 include in the format string. Thus, hexformat_pre("08") will
621 return "0x08x" (if the working language is language_c).
622 Made hexformat() and hex_to_string() calls to the above
623 with "" as the prefix argument.
625 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
626 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
627 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
628 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
629 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
630 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
631 valprint.c, vax-pinsn.c
633 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
634 calls to hexformat() and hex_to_string(). Format strings without
635 the leading "0x" were ignored.
637 depend Updated to take the above into account.
640 Tue Jun 25 15:27:18 EDT 1991
642 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
643 and type_check_t to keep track of the current state of
644 range and type checking.
645 main.c Added the variables range_mode, range_check, type_mode,
646 and type_check to record the current state of range and
647 type checking. Added initialization code to main().
648 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
652 Tue Jun 25 17:57:08 EDT 1991
654 dbxread.c process_one_symbol() updates the variable (enum language)
655 source_lang based on the extension of the filename
656 contained in the N_SO sybmol that started this symtab.
657 When end_symtab() is called, the value of source_lang is
658 put into the language field.
659 stack.c select_frame() sets working_lang (and possibly type_check
660 and range_check) to the language field of the symtab
661 associated with the frame that is selected if working_mode
662 is language_auto. If working_mode is language_manual, a
663 warning is printed and working_lang is not set.
664 language.c Added the function set_type_range(), which sets the value of
665 type_check and range_check (if their modes call for
666 automatic setting) based on the current value of
667 working_lang. A non-zero argument will cause the current
668 settings to be output.
671 Wed Jun 26 14:51:40 EDT 1991
673 eval.c Added range checks on assignment.
674 m2-exp.y Added the grammar for sets to the language. Currently,
675 these do not do anything except print an error message.
677 Wed Jun 26 17:01:04 EDT 1991
679 m2-exp.y Added the ability for parse_number() to parse negative
680 numbers. A global flag is set upon encountering a unary
681 minus. This was done to make, for example, 1 parse as a
682 CARDINAL, and not as an integer, per Wirth's examples in
683 Programming in Modula-2 ed.4.
684 valprint.c Added support for "set radix 2" by then setting
685 output_format to 't'.
686 eval.c Implemented range checking on subrange types. Added calls
687 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
688 Implemented MIN and MAX for ennumerated types. The
689 minimum value of an ennumerated type is defined by Wirth
690 as the first identifier, and the maximum as the last.
691 m2-exp.y Made octal numbers ending with "B" be characters and those
692 ending with "C" be numbers, per Wirth's book. (p. 34)
694 Thu Jun 27 14:11:52 EDT 1991
696 stack.c select_frame() now only sets working_lang, it does not
697 notify the user. If working_mode is language_manual, then
698 a warning is issued once.
699 main.c At the end of each call to execute_command(), working_lang
700 is checked against the local static (enum language)
701 current. If they differ and working_mode is
702 language_auto, the new settings of language, type and
703 range checking are printed out.
704 stack.c Modified frame_info() to include the language of the
705 current frame in the output of "info frame".
706 language.[ch] Added the function language_str() which returns the name
707 of the current language.
709 Fri Jun 28 15:33:14 EDT 1991
711 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
712 the language. INCL and DECL currently cause an error,
713 since sets are not implemented yet. INC and DEC are
714 implemented as PREINCREMENT/PREDECREMENT with one
715 argument, and as ASSIGN_MODIFY with two arguments.
716 eval.c Added type checking to the above cases.
717 value.h Added not_lval_constant to the lval_type ennumerated type.
718 not_lval_constant means that the value is a constant
719 value; that is 3 or 'a' or TRUE, not as in a constant
720 identifier. This is used to help coerce numbers such as 3
721 to either signed or unsigned numbers.
722 valops.c Added the function value_coerce_constants() which coerces
723 constant integers as following: if one is a constant and
724 the other is not, the constant's type is set to the type
725 of the other argument. If both are constants and one is
726 signed, the other is converted to a signed constant.
728 Sat Jun 29 17:26:29 EDT 1991
730 valarith.c Added a better range checker. It now checks range
731 (successfully) on integral operations [+-] (signed and
732 unsigned) for any C sized type. Still does not work well
734 int_in_size() returns an integer that is coerced to fit into
735 specified number of bytes.
737 Mon Jul 1 13:04:14 EDT 1991
739 language.[ch] Added the function binop_result_type(), which returns the
740 builtin (struct type *) type that would be the result of a
741 binop on the two values V1 and V2.
743 Wed Jul 3 19:22:53 EDT 1991
745 source.c Extended source_info() to include the source language in
746 the output from "info source".
748 Fri Jul 5 13:48:52 EDT 1991
750 utils.c Moved the support functions for the GDB set/show commands
751 dealing with language into language.c.
752 language.c Added the function language_info(), which displays info
753 about the current working language, type and range check
754 settings. Called via the GDB command "info language".
755 Added an initialization routine _initialize_language(),
756 that sets defaults for the language, type and range
757 variables and sets up the new GDB commands.
758 main.c Language setup moved to language.c.
761 Mon Jul 8 10:10:22 EDT 1991
763 valarith.c Debugged the range checker for arithmetic. Still does not
764 work for multiplication very well.
766 Mon Jul 8 12:40:37 EDT 1991
768 language.[ch] Added the function value_true() which returns non-zero if
769 its argument represents a boolean true value.
770 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
771 check the truth of an expression.
773 Thu Jul 11 12:51:34 EDT 1991
775 language.[ch] Added the predicate structured_type(), which returns
776 non-zero if the argument is a structured type.
777 Added the predicate pointer_type(), which returns non-zero
778 if the argument is a pointer type.
779 eval.c Added the ability to do addition and substraction on
780 pointers and integers. This case simply bypasses the
783 Thu Jul 11 14:41:42 EDT 1991
786 Added the symbol N_DEFD (0x4a) which is a definition
787 module dependency that is used by the GNU Modula-2
788 compiler and the linker. It is not important to GDB,
789 except that [dbx|coff|mips]read.c should ignore these
792 Fri Jul 12 16:07:00 EDT 1991
794 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
795 0 in val_print(). Also added statements to the else part
796 to coerce type (argument to val_print) to a pointer type
797 if it is an "array of unspecified length".
798 valops.c Added the function value_m2_string(), which returns a
799 (value) value which is a constant string, whose type is
800 (ARRAY [0..n] OF CHAR). The length field of the type
801 structure is set to zero, so it will be interpreted as an
802 "array of unspecified length".
803 stack.c Moved the language/frame mismatch check to
804 main.c:execute_command().
805 main.c The working language is recorded each time
806 execute_command() is executed. If working lang has
807 changed during its execution, then the new
808 language/type/range info is printed out for the user. If
809 the working language does not match the language of the
810 frame, a warning is issued.
812 Sat Jul 13 16:16:39 EDT 1991
814 eval.c Moved all the type-checking stuff for operators to
815 language.[ch] language.c. This is so we can keep language-specific
816 stuff (like for what type operators are defined) in
818 language.[ch] Added the function binop_type_check(), which checks to see
819 if its two (value) arguments are type-compatible with its
820 opcode argument. The opcode should represent an operation
821 involving an operator. Also added the macro function
822 unop_type_check, which calls binop_type_check with a
823 NULL second argument.
824 expprint.c Added Modula-2 operators to the op_print_tab, so info
825 expression.h break works correctly. Also added "op_string", which
826 returns the string corresponding to the (enum exp_opcode)
827 opcode that is its argument.
830 Sat Jul 13 18:26:18 EDT 1991
832 coffread.c Added code to record the type of function arguments with
833 each paricular function. Code is very similar to that
835 dbxread.c Moved add_param_to_type() to symtab.c
836 symtab.[ch] Added function add_param_to_type() from dbxread.c
838 *** NOTE: The above additions have not been tested.
840 Mon Jul 15 12:50:47 EDT 1991
842 langauge.[ch] Added the functions type_error and range_error, which work
843 like error() except if the type/range mode is set to
844 *_mode_warn, then they do not do a return_to_top_level(),
845 but merely print a warning.
846 Also changed [set|show]_[type|range]_command() to support
847 the new "warn" feature.
849 Thu Jul 18 17:50:54 EDT 1991
851 mipsread.c Added code to record the type of function arguments with
852 each particular function. Code is very similar to that
855 *** NOTE: The above additions have not been tested.
857 Fri Jul 19 11:19:10 EDT 1991
859 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
860 UMIN_OF_SIZE, which when given a size of a numeric type,
861 return the maximum and minimum value it can hold. UMAX...
862 and UMIN... return the result for unsigned types.
863 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
864 struct types. They call above macros.
865 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
866 avoid a name conlict with the above.
867 c-exp.y Added range checking on numeric constants in
868 parse_number() for completeness.
869 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
870 return 0 if working_lang is not language_c.
872 Thu Aug 8 14:17:22 EDT 1991
876 breakpoint.c Documentation strings of some commands changed to
877 eliminate the references to the C language where
880 Tue Aug 13 15:48:03 EDT 1991
882 m2-exp.y Added qualified identifiers to the grammar. The semantics
883 are slightly different from those of the GDB operator ::
885 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
886 type_exp, where type_exp is any valid type expression.
888 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
889 printcmd.c Modified ptype_command() so it actually parses the input
890 (necessary for type expressions with scope qualifiers).
891 Added the function ptype_eval() which expects an
892 expression composed of one OP_TYPE element.
893 *.[ch] Replaced all occurences of parse_c_expression with
895 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
897 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]

903 * infrun.c (child_attach): Lint.
904 * solib.c (find_solib): Handle shared libs version 2.
906 Small fixes from David Wood:
908 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
912 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
913 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
915 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
916 chars_per_line is at maximum (user typed `set width 0'). Fix
917 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
919 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
921 * coredep.c: include ptrace.h where necessary.
922 * mipsread.c(parse_lines): fix unsigned char problem that was
923 messing up line numbers on SGI's and possibly other MIPS based
925 * infrun.c (child_create_inferior): use better test to check
926 return val from setpgrp().
927 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
928 for sgi/irix support.
930 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
932 * mipsread.c (parse_symbol): Put non-static procedures
935 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
937 Patch together `text_start' and `text_end' for 29K port.
939 * exec.c (exec_command): If NEED_TEXT_START_END, define the
940 variables and set them based on the exec file.
941 * am29k-tdep.c: declare text_start.
942 * valops.c (call_function_by_hand): declare text_end.
944 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
945 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
946 because machines that do this will also have to know to
947 set NEED_TEXT_START_END. Besides, it was a redundant way to
949 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
950 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
953 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
955 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
957 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
958 Pass MUNCH_DEFINE to munch whenever we run it.
959 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
960 format string; use 0x%x instead.
961 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
962 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
963 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
964 * inflow.c: Handle `short' process group IDs.
965 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
966 and check for ptrace errors.

969 (read_coff_symtab): Use it to find the text [and absolute?] sections.
970 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
971 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
972 Merge target arm case with other "easy" cases. Add target
973 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
974 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
976 * minimon.h, remote-adapt.c, remote-mm.c: Add.
977 * munch: Cope with RT/PC putting fns in data segment.
978 Restore ability to override `nm' by specifying MUNCH_NM.
979 * xconfig/rtbsd, xconfig/ultra3: New host systems.
980 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
981 and remote-adapt. Remove encapsulated coff #define's (the
982 support should go in BFD, and gdb shouldn't know or care).
983 * tconfig/a29k-kern: Same, but for remote kernel debugging.
984 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
985 * tm-29k.h: Update BADMAG (though it should go away).
986 Allow the register definitions to be overridden in another
987 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
988 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
989 DUMMY_SAVE_GR96, for handling kernel calling conventions
990 that use GR64+ rather than GR96+.
991 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
992 remote debugging of Ultra3 kernel. Includes tm-29k.h and
993 overrides various things.
995 * remote-mm.c (mm_attach, mm_wait): Handle attach like
996 child_attach does, making a clean stop in the newly attached
1000 * coffread.c: Make coffread independent of any particular
1001 variant of COFF. Avoid #include-ing any particular one except
1002 internalcoff.h. BFD now passes key values for symbol reading
1003 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1004 and the symbol masks and shifts); use them.
1005 Remove obsolete end_of_text_addr.
1007 * exec.c: Remove unused include files.
1009 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1011 * Makefile.in (documentation targets): Pass $(M4).
1012 Bugfix from eggert@twinsun.com (Paul Eggert).

1016 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1018 * Makefile.in (VERSION): Update to 4.0.3.
1020 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1022 * core.c (core_file_command): Print frame at coredump with
1023 its level number, by calling print_stack_frame.
1024 * frame.h: Add selected_frame_level, print_stack_frame.
1025 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1026 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1027 Change print_sel_frame and print_selected_frame callers to
1030 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1031 * symfile.c (free_named_symtabs): Ditto.
1032 * main.c (main): wrap_here needs an arg.
1033 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1034 (solib_add): Avoid noise.
1035 (solib_create_inferior_hook): Lint.
1036 (sharedlibrary_command): Move dont_repeat to here.
1037 * utils.c (error): Call wrap_here to force buffered output.
1039 Small patches from Peter Schauer:
1041 * coffread.c (start_symtab): Free any existing line_vector before
1043 (read_coff_symtab): Ditto for type_vector.
1045 * source.c (lines_to_list): New variable, replacing function.
1046 (all uses): Use as variable.
1047 (_initialize_source): Add 'set listsize' and 'show listsize'.
1048 * utils.c (lines_to_list): Remove function.
1049 * stack.c (print_frame_info): Use as variable.
1050 * defs.h (lines_to_list): Remove declaration.
1052 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1054 * breakpoint.c (insert_breakpoints): Restore warning about
1055 the program might be running in another process, but only for
1056 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1057 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1059 * utils.c (error): if error_pre_print is set, print the string
1061 * main.c (main, print_gnu_advertisement, print_gdb_version):
1062 Reformat legalese so it always prints, but acts as an "I'm here"
1063 message while symbols are being read. If any errors occur,
1064 print a few newlines to set off the message and start it at the
1065 left margin. Remove mention of "help" command, and don't yak
1066 about symbol reading.
1067 (catch_errors): Error string is now printed first in case of
1069 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1070 suggest the "help" command.
1072 * Makefile.in (VERSION): Set to 4.0.2.
1074 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1076 * .gdbinit: Remove useless "rr" command. Set complaints
1077 to 1 for people debugging gdb.
1079 * breakpoint.c, remote-vx.c: Reword strings printed by
1080 catch_errors callers.
1082 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1084 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1085 (Fix from kenc@viewlogic.com.)
1087 Fix some infrastructure to be able to cope with host and target
1088 machines with different sized basic types (ints, ptrs, etc).
1089 (Idea from pierre@la.tce.com (Pierre Willard).)
1091 * values.c (value_from_longest): Rename from value_from_long.
1092 Handle pointer types as well as integers, so that targets with
1093 different pointer sizes from the host can be accomodated.
1094 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1095 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1096 uses of value_from_long to value_from_longest.
1097 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1098 the correct pointer type to value_from_long{est}.
1100 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1102 * remote-vx.c: Remove obsolete code for calling functions via
1103 vxworks kludge interface (it referenced value_from_long).
1105 * valops.c (value_string): Find malloc with lookup_misc_func, not
1108 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1110 Make writing to files work properly. (Fixes to BFD are also needed.)
1112 * core.c (core_open): Open file ourselves, read or r/w, depending on
1113 write_files. Use bfd_fdopenr.
1114 * gdbcore.h (write_files): New variable.
1115 * exec.c (write_files): Define variable, add set&show for it.
1116 (exec_file_command): Use write_files to open for read or r/write.
1118 Make shared library reading happen automatically. These changes
1119 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1121 * inferior.h (stop_soon_quietly): Add to exported variables.
1122 * infrun.c (child_create_inferior): call solib hook, if defined.
1123 (child_attach): call solib hook, if defined.
1124 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1125 (find_solib): Use lookup_misc_func rather than hand-rolled.
1126 (symbol_add_stub): New stub for catch_errors.
1127 (solib_add): Avoid output if !from_tty. Catch errors rather
1128 than just calling symbol_file_add and bombing.
1129 (solib_create_inferior_hook): Interface with the target process
1130 to let it read and alloc shared libs, then figure out what it did.
1132 * core.c (validate_files): Fix typo, soften warning.
1133 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1135 * utils.c (fputs_demangled): Avoid duplicate printing if
1136 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1138 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1139 (Fix from pierre@la.tce.com (Pierre Willard).)
1141 * main.c (catch_errors): Change argument to a char * from an int,
1142 since a char * can point to a struct full of glop, but an int
1143 is not guaranteed to be able to hold a pointer.
1144 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1145 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1146 * core.c (core_open, solib_add_stub): Adapt.
1147 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1149 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1151 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1152 by adding .NOEXPORT target.
1154 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1158 * Makefile.in (VERSION): Roll to 4.0.
1159 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1161 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1163 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1166 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1169 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1171 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1172 reflect above name change
1174 * WHATS.NEW: correct pointer to refcard.
1176 * doc/gdb.texinfo: update New Features, Installing
1178 * doc/gdbint.texinfo: add short description of configure +template
1180 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1182 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1184 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1186 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1187 tar file, add dependencies for referenced doc files.
1189 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1191 * coffread.c, symfile.c, stack.c: saberized.
1193 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1195 * doc/refcard.tex: permuted Essential Commands sec
1197 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1199 set/show symbol-reloading
1200 default set complaints 0
1202 RET-repeat disabled after prompted long displays
1203 processID (attach) interpretation of 2nd GDB cmdline arg
1205 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1207 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1208 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1209 breakpoint.c, main.c: lint.
1211 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1213 Install new configuration scheme for GDB and friends.
1215 * config.sub: Translate ordinary names to three-part names.
1216 * configure: Use three-part names internally.
1217 * configure.in: Translate three-part names to filenames.
1219 * README, WHATS.NEW: Update for gdb-4.0.
1220 * Makefile.in: Roll VERSION to 3.99.
1222 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1224 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1225 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1226 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1227 to single structures rather than arrays; when passing
1228 their address, use &. This avoids trouble with bdead compilers.
1229 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1230 instead. This avoids portability headaches.
1231 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1233 * source.c (open_source_file): Avoid ANSI const bdeath by
1234 skipping declaration and then casting result value.
1235 * tm-hp300bsd.h: Clarify comment.
1236 * utils.c (strstr): Result is const char *; ANSI bdeath.
1237 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1238 since system include file defines it differently from "defs.h",
1239 though the two are equivalent for our purposes.
1240 * tconfig/hp300bsd: Add m68k-tdep.o.
1242 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1244 * tconfig/sun*4: Remove warnings about system assembler.
1246 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1248 * mcheck.c: Avoid warning about undeclared abort fn.
1249 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1250 it causes recursive calls to error() when used in cleanups.
1251 To do so requires that we make it a function, so we do.
1252 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1253 * utils.c (do_cleanups): Remove the current cleanup from the
1254 chain *before* calling it, in case error() is called from it.
1255 The result won't be pretty, but won't be an infinite loop either.
1257 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1259 * dbxread.c (read_struct_type): Grok anon structs for C++.
1260 (vb_name, vptr_name): Null terminate these strings.
1262 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1264 Minor bug fixes from BSD Net2 gdb:
1266 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1267 returns 0, there is no previous frame.
1268 * breakpoint.c (commands_command): If !from_tty, don't call
1269 input_from_terminal_p().
1270 * dbxread.c (record_misc_function): Speed up slightly.
1271 (compare_psymbols): Ditto.
1272 * infcmd.c (do_registers_info): Take a second argument to
1273 determine whether to print float registers. "info registers"
1274 does not do so anymore. "info all-registers" does, now.
1275 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1277 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1278 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1282 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1283 executing_breakpoint_commands if we are interrupted by error.
1284 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1285 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1286 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1287 catch_errors() so we can setup the frame regardless of whether
1288 the shared libs work.
1289 * ieee-float.c (double_to_ieee_extended): Get exponent from
1290 right place in little-endian systems. From John Carey.
1292 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1294 * main.c: Remove unused terminating_signals and catch_termination().
1295 (long_options): Terminate with a zero element.
1296 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1297 (gdb_readline): Make call-compatible with readline.
1298 (init_signals): Improve comments re vfork vs. signal.
1300 * utils.c (prompt_for_continue): Use new gdb_readline().
1301 If we prompt for continuation, we don't let CR repeat the previous
1302 command, once we get back to a prompt. It's too easy to keep
1303 hitting CR, expecting "--more--" prompts, and have some long
1304 command start repeating on you.
1306 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1308 * blockframe.c (frameless_look_for_prologue): Speed up by
1309 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1310 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1311 Define two variants, one faster.
1312 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1313 and return zero, rather than giving an error.
1314 (setup_arbitrary_frame): Initialize the PC in the new frame.
1315 (skip_prologue): Add a second arg saying whether we're just
1316 checking for a frameless function or not.
1318 * core.c (core_open, core_close, core_xfer_memory): Move
1319 section table pointers and bfd* into the target_ops.
1320 (core_open): Allow errors in shared lib reading, etc.
1321 (core_files_info): Describe shared library sections.
1323 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1324 exec_files_info, set_section_command): Move section table
1325 pointers and bfd* into the target_ops.
1326 (add_to_section_table): Add BFD to section table.
1328 * target.c (target_xfer_memory, target_info): Pass target to
1329 xfer_memory and target_info functions.
1332 * gdbcore.h: Move struct section_table.
1333 * target.h: New home of struct section_table.
1335 * solib.c (solib_add): New argument is the target_ops whose
1336 section list is to be added to, if any. Reallocate the
1337 sections in that target to add any that come from shared libs.
1338 (throughout) so_sections renamed to sections.
1339 (solib_xfer_memory): Deleted.
1340 * tm-sunos.h (SOLIB_ADD): Add target argument.
1341 (SOLIB_XFER_MEMORY): Delete.
1343 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1344 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1345 from target_ops. It's the same on all targets. Add two section
1346 pointers to target_ops.
1348 * stack.c (find_relative_frame): Dump ancient algorithm for
1349 "down", just use handy "next" pointers.
1350 (frame_command): Don't error if there is no stack; let user
1353 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1354 modifies static state in the parent process; new_tty itself
1355 runs in the child and modifies the child's file descriptors
1356 to match the saved static state.
1357 * infrun.c (child_create_inferior): Call new_tty_prefork,
1360 * infptrace.c (child_xfer_memory): Add ignored target arg.
1361 * remote-eb.c (eb_xfer_inferior_memory): ''
1362 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1363 * remote-vx.c (vx_xfer_memory): ''
1364 * remote.c (remote_xfer_memory): ''. Rename from
1365 remote_xfer_inferior_memory.
1367 * main.c (main): Only try to attach "corefile" argument if
1368 it starts with a digit.
1370 * symfile.c (symbol_reloading): New "set/show" variable.
1371 (symbol_file_add): Shorten message about symbol reading.
1372 (add_symbol_file_command): Merge with add_syms_addr_command,
1373 since this should work on all targets now.
1374 (stop_whining): Default to zero, to shut up complaints
1375 about bad symbol tables on many systems.
1376 (free_named_symtabs): Just exit unless symbol_reloading.
1378 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1379 and add comment explaining shared library screw.
1381 * source.c: #if defined => #ifdef.
1383 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1385 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1387 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1389 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1390 (doc/Makefile knows how to make one for local config)
1392 * Makefile.in: use doc/Makefile for doc targets
1394 * doc/Makefile: GDB documentation now has its own Makefile
1395 doc/refcard.tex: renamed from "gdbrc.tex"
1396 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1397 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1400 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1402 * values.c (baseclass_addr): When reading target memory, use the
1403 length of the basetype, not the upper type. We've only malloc'd
1404 enough space for the basetype, leading to errors in free().
1406 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1407 ends up as a function specially, since we know the actual type of
1408 the pointed-to address. This (somewhat) fixes display of
1409 expressions that include misc_function_vector names. Try `cond 1
1410 !strcmp("a","b")' then `i b'.
1412 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1413 The child can be proceeded from inside wait_for_inferior in
1414 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1415 getting skipped in that case.
1417 * expprint.c (print_subexp): Use filtered output, since the
1418 subroutines we call use it, otherwise the output is horribly
1419 mangled, since output of wrappable stuff comes out late.
1421 * Makefile.in: Bump VERSION to 3.98.1
1423 * infrun.c (child_create_process): Use execlp to find the
1424 shell to exec our target program. This requires some fiddling
1425 with `environ' since there is no execlpe().
1427 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1429 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1430 Minor rearrangement of refcard permits two new make targets--
1431 gdbrc.dvi DVI output for refcard, using CM fonts
1432 gdbrc.ps PostScript refcard, using PS fonts
1434 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1438 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1439 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1441 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1443 * doc/gdb.texinfo: last changes for release.
1444 Minor typo and formatting fixes; incorporated most fixes remaining from
1445 filed mail commenting on earlier drafts.
1447 Added warnings: pipes don't work in run command;
1448 conditions are converse of assertions;
1449 step over fn without debug info goes to next fn;
1450 vars may have "wrong" values near fn entrance, exit
1452 Added example from Kingston on printing repeated nonadjacent values
1454 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1455 shell mode for signals
1457 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1458 doesn't sound so much like its parent "Stopping and Continuing"; also
1459 moved entries on continue to top of section, so they don't get lost.
1461 Improved installation directions in appendix, added manual formatting
1464 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1466 * configure.in: Remove xm.h and tm.h even if we aren't linking
1467 new ones, so "./configure sun4; ./configure none" does the right
1468 thing. Assume that alldeps.mak and depend are already built in
1469 srcdir, and avoid running "make" (particularly "make depend",
1470 which involves "gcc") from inside configure. Build Makefile
1471 directly rather than building Makefile.conf first.
1472 * configure: Regenerate with above changes.
1473 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1474 to 3.98. Revise gdb.tar.Z procedure to produce a file
1475 called gdb-$(VERSION).tar.Z but which unpacks into a
1476 directory called "gdb". Move non-source files out of
1477 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1478 (depend): Don't try to do "gcc expread.y".
1479 (expread.o): Update dependencies by hand.
1481 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1484 Fixed a variety of small typos that prevented info from formatting
1485 cleanly; altered too-long heading for GPL Appendix, as discussed
1486 w/RMS; Changed date on cover to July 91.
1488 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1491 (1) Applied some fixes due to comments from Larry Breed (easier ones
1492 through chapsec 5.2)
1493 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1494 it's broken in latest texinfo
1495 (3) Introduced *some* use of [] for optional arguments, where
1496 explanation is not simpler by listing cmd w arg and cmd w/out arg
1497 separately. Still not using @deffn.
1498 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1499 couple of headings are too long. Need patches to texinfo or revision
1502 * Partial update to README (which still needs work for this
1503 release!): (1) use of configure corrected for new script,
1504 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1506 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1508 * symtab.c (lookup_symbol): Don't complain right off about
1509 no debug symbols; use the misc function vector first.
1510 (list_symbols): Use misc function vector to find symbols
1511 that don't have debug info, and print them.
1512 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1513 PC range doesn't match symtab PC range, as it does on the
1514 MIPS because our symtab reading isn't perfect.
1516 * dbxread.c (dbx_symfile_read): Make warning about
1517 "no debug symbols" slightly nicer.
1519 * source.c (select_source_symtab): If "main" symbol exists,
1520 but decode_line_spec can't find line info, don't just return
1521 a zero; try other source symtabs or give an error.
1523 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1524 their low addresses first, then rip through fixing high addrs.
1526 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1527 <runene@ifi.uio.no>.
1528 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1530 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1532 * Minor, mostly mechanical, cleanup of doc subdir for clean
1533 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1534 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1536 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
1538 Mostly MIPS and general symbol-reading fixups.
1540 * doc/gdbint.texinfo: Add documentation on symbol-reading
1543 * mipsread.c: Remove kludges around #include "ecoff.h".
1544 Remove redefinitions of a_magic, etc, no longer used.
1545 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
1546 Fix global overview comments to match symfile.c protocol.
1547 (mipscoff_new_init): Eliminate cur_hdr if we have one.
1548 (mipscoff_symfile_read): Eliminate unused code. Avoid
1549 sorting all the symtabs, when all we have read here is psymtabs.
1550 The symtabs are sorted as they are created anyway. Tell
1551 condense_misc_bunches whether we're mainline.
1552 (psymtab_to_symtab_1): Pass filename when recursing, to make
1553 stack trace more informative.
1554 (parse_partial_symbols): Assume cur_hdr as argument.
1555 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
1556 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
1557 the TYPE_NAME of char *, since that's done in symfile.c.
1558 (free_numargs, parse_symbol, add_symbol, add_block,
1559 shrink_linetable): Declare these fns void.
1560 (upgrade_type): Convert tree of if's to switch. Clean up
1561 bogus "off == 0" handling with a complaint. Avoid setting
1562 field bitpos and bitsize of array with lower and upper bounds.
1563 Check specified bitsize of elements against their actual type's
1564 bitsize, and complain if different. Complain about unknown
1566 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
1567 (psymtab_to_symtab_1): Print names of subsidiary files that
1568 are being read in. FIXME, we read far too many files. This code
1569 is not the problem, the problem is in parse_fdr where the psymtabs
1571 (cross_ref): Result should indicate that we used one aux entry
1572 normally, or two if we encountered a "next" entry. This used
1573 to leave the caller pointing at the wrong aux entry.
1574 (add_symbol): If overflowed cur_block, reallocate it larger,
1575 chase all pointers to it, and complain(), rather than clobber memory.
1576 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
1577 (new_field): Only allocate one field initially, not two.
1578 Pull ++ out of macro argument. Simplify.
1579 (_initialize_mipsread): Avoid initialization of importd
1580 global_psymbols and static_psymbols.
1582 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
1583 to properly set pst->symtab; avoid searching for it.
1584 (symfile_fns): Improve comments, add a FIXME.
1585 * dbxread.c: Update comments to reflect symfile protocol.
1586 (read_ofile_symtab, end_symtab): Return the symtab.
1587 (psymtab_to_symtab_1): Set pst->symtab.
1589 * coffread.c (coff_symfile_read): tell condense_misc_bunches
1590 whether we're mainline.
1592 * symfile.h (sym_fns): Remove unused sym_discard member.
1593 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
1595 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
1596 the environment variable is not.
1597 * infcmd.c (finish_command): Use filtered printfs.
1598 * cplus-dem.c: Add struct tags to a few unnamed structs.
1599 * valops.c (value_coerce_array): Improve comments.
1600 * valprint.c (type_print_varspec_suffix): Print array size only
1601 if greater than zero.
1602 * m88k-tdep.c: Shift some lines left by one space, that had
1603 apparently been trashed at some point.
1604 * TODO: More things to do, a few got done.
1606 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1608 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
1609 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
1611 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
1612 * expread.y, findvar.c, symmisc.c: Ditto.
1613 * printcmd.c (address_info): Update printed forms of LOC_
1614 symbols. Elim LOC_EXTERNAL.
1615 (print_frame_args): Keep track of param stack offsets before
1616 re-looking up to find the local register param is kept in.
1618 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
1619 Further integration of mipsread into gdb. Eliminate unused
1620 routines, duplicate declarations. Handle static symbols in
1621 psymtabs as well as external symbols. When reading symtabs,
1622 insert symbols into the correct block (global, static, or a local
1624 (read_mips_symtab, parse_partial_symbols): Don't pass useless
1626 (mipscoff_symfile_read): Don't call select_source_symtab.
1627 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
1628 rather than SYMBOL_VALUE.
1629 (parse_external): Comment clobbering of top_stack.
1630 (parse_partial_symbols): Update comments. Allocate and parse
1631 static symbols as well as external symbols. FIXME, enum values
1632 are not handled in this pass, but should be. Inline new_psymbol.
1633 Use SYMBOL_VALUE_ADDRESS.
1634 (psymtab_to_symtab_1): Read symbols into global static block
1635 by default (until enter some function's local block context).
1636 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
1637 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
1639 * source.c (select_source_symtab): Select a source symtab
1640 from either the symtabs or, failing that, the psymtabs.
1641 (list_command): Update error message.
1642 (forward_search_command, reverse_search_command): Use getc, not
1643 fgetc, for speed. FIXME, add comment about buffers that die if
1644 overrun by long line.
1646 * values.c (unpack_field_as_long, modify_field): Avoid shifting
1647 by an entire word, which is not portable, if we have a 32-bit
1648 field. (Code in dbxread.c already turns such bitfields, if
1649 aligned, into ordinary ints, but fixing this will help for other
1650 symbol formats and for future changes.)
1651 * core.c (core_open): Handle ANSI const brain death.
1652 * utils.c (vprintf): Fix varargs typo.
1654 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1656 * findvar.c (find_var_value): Handle &function better.
1657 * TODO: Document work needed on &fn and &array.
1658 * printcmd.c (print_address_symbolic): New arg is the prefix
1659 to print if a name is printed.
1660 (print_address_demangle): Honor "set print address" now.
1661 Use new arg above to improve spacing of output.
1662 * valprint.c (val_print): When printing function pointers,
1663 print symbolic form too.
1664 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
1666 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1668 * core.c (memory_error): Reword error msg to mislead less.
1670 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
1672 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
1673 parse_partial_symbols): Use newer BFD internals (external_filehdr
1674 and external_aouthdr), byte-swap the fields that we care about
1675 before using them, and make the file header data local to
1676 read_the_mips_symtab rather than global.
1678 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
1680 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
1681 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
1683 * main.c (command_line_input): Flush stdout and stderr
1684 before every call to readline. This reportedly fixes a bug
1685 that comes up in Sys V running emacs-gdb and/or xxgdb,
1686 when stdin/out are pipes or sockets.
1688 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1690 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
1691 Avoid declaring Makefile dependencies, because GNU Make stupidly
1692 tries to update it if we do.
1694 * coffread.c: Revise for minor changes to bfd internal coff
1697 * configure: If -template= is given a relative path, make it
1698 absolute before recurring in subdirectories.
1700 * configure, configure.in, Makefile.in: Install "configure" script
1701 as replacement for config.gdb.
1702 * config.gdb, Makefile.dist, Makefile.sdir: Remove
1703 * README: Update for configure, mostly. FIXME.
1705 * Add dec3100 as equivalent to littlemips. Indicate in all host &
1706 target config files that they are for the host. When the lines
1707 get copied into the Makefile, this makes it more obvious what's
1710 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1712 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
1713 tabs, which end up in the disassembler output inadvertently.
1715 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1717 Make it compile cleanly in an ANSI GCC2 environment.
1719 * blockframe.c: <stdio.h>
1720 * cplus-dem.c: free takes a void *, ifdef __STDC__
1721 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
1723 * defs.h (alloca): Avoid doing anything if alloca already def'd.
1724 * stddef.h, stdlib.h: Remove these files.
1725 * symtab.c: Avoid declaring qsort, close.
1726 * symfile.c: Avoid declaring close.
1727 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
1728 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
1730 Assorted other changes.
1731 * dbxread.c: include "libaout.h", not "liba.out.h".
1732 * printcmd.c (print_frame_args): Set recurse properly for
1733 indentation of struct and array parameters.
1734 * valops.c (value_cast): Allow cast to void.
1735 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
1736 single_step() in a target-independent fashion.
1737 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
1738 set up to be ready to continue. This makes us target independent.
1739 * infptrace.c (child_resume): Remove call to single_step; now
1740 can single step a SPARC target of any kind.
1742 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1744 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
1745 docn into separate sections---basically chapters, plus two loose
1746 pieces that can be configured to go in different places. This
1747 allows GNU m4 to preprocess the manual without coredumping.
1749 * Makefile.dist: tell TeX where to find texinfo.
1751 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1753 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
1754 the new target "rdl-apps.texinfo" which captures the Makefile
1755 variable that records where to find the Readline libraries.
1757 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
1759 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
1760 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
1761 * defs.h (const, volatile): Only define if not already defined.
1762 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
1764 * README: Update for release 3.95.
1765 * config.gdb: Don't create readline dir in subdir builds.
1766 * main.c: Include with "..." form for non-system include files,
1767 so "gcc -MM" for "make depend" works.
1768 Include readline files with "...h" rather than <readline/...h>.
1769 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
1771 * coffread.c: Undo minor damage done by Rich Pixley. Use
1772 different internal and external representations of COFF
1773 data structures. Use new BFD routines for swapping them in and
1775 * symfile.c (free_named_symtabs): Avoid freeing file names that
1776 are null or empty. Old i960 tools seem to produce files that
1777 claim to have empty names, causing each successive file read
1778 to blow away the previous one.
1779 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
1780 Move deferred_stores to top of file, but don't separate its
1781 #define's from its variable. Add commentary.
1782 * Makefile.dist: Fix Rich damage; undo "configure" changes in
1783 favor of keeping the (working) config.gdb. Move readline
1786 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
1788 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
1790 * infptrace.c (fetch_registers): no result, since now void.
1791 * tconfig/news: target depends on m68k-tdep too.
1793 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1795 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
1798 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
1799 applied various small fixes due to or inspired by RMS comments
1801 * doc/gdb.texinfo: finished using all RMS comments, save those for
1802 appendices on readline and cmd history (which are in other source
1805 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1807 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
1808 chapter 9; (2) documented 'break' command's menu mode for
1809 overloaded names, in response to hgs problem report C++ p-31
1811 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1813 * doc/gdb.texinfo: (1) better introductory example; (2) more
1814 consistent use of @code, @samp, @file, @kbd throughout; small
1815 cleanups to first three nodes; (3) new "Contributors" node;
1816 (4) Appendix, Renamed Commands; (5) divert specialized startup
1817 instructions to "Targets" chapter for generic manuals, while
1818 leaving them up front for manuals specific to specialized
1819 environments; (6) apply fixes from RMS comments through chapter 4.
1821 * pretex.m4: modify explanatory text slightly (and redefine
1822 "regexp") to keep GNU m4 from complaining. (It still crashes
1823 later, but one step at a time...)
1825 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
1827 * readline/readline.c (update_line): Avoid dereferencing a pointer
1828 before comparing it to its bounds. Saber caught this.
1829 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
1830 and only set PC if tgetstr returned non-null. Saber caught this.
1832 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1834 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
1835 stuff for config manual) here where it counts; updated
1836 to use new subdir structure (gdb/doc/).
1838 * Makefile: generated from above via
1842 * gdbint.texinfo: added instructions on generating gdb.info* files
1843 locally for release. These are ordinary info
1844 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
1845 Makefile)---but due to use of texinfo 2, can't count on makeinfo
1846 to generate these, so we distribute them already formatted.
1848 * gdb.texinfo: included full Info node and menu crud (as generated
1849 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
1851 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
1852 put in comments-for-future gdb.info target (one day makeinfo will
1855 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1857 * gdb.texinfo: Updated to include new or old undocumented
1858 commands, at least the following (perhaps some others I forgot to
1859 record): info f, info float, info path, info program, info s, info
1860 set, info source, info terminal, info types, info user, set/show
1862 Also covered all recent GDB command renames for v4.
1864 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1866 * mipsread.c: Rather than keeping count of how many symtabs
1867 and psymtabs we have, for sorting purposes, count them when
1868 we need to sort. This fixes bug in rereading of symbol tables.
1870 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1872 * infcmd.c: renamed "info path" to "show paths"
1873 * gdbrc.tex: documented above.
1875 Wed May 8 04:51:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1877 * remote.c: Fix comments.
1878 * utils.c (error): Force out any pending wrap output.
1880 Sat May 4 11:11:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1882 * Makefile.dist: Roll VERSION to 3.95.
1883 Fix up "saber_gdb" to work again.
1884 * saber.suppress: Update.
1886 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
1887 symtab.h, target.c, target.h: Lint.
1888 * core.c: setup and select frame after reading shared libs,
1889 else reading shared libs will clobber them. Lint.
1890 * utils.c (error): Force out any buffered wrap text.
1892 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1894 * remote.c: Remove decls of memory_insert_breakpoint
1895 and memory_remove_breakpoint, no longer used. (Suggestion of
1898 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
1899 to make it easier to interface to "configure"'d libraries.
1901 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
1903 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
1904 aliases for set/show print.
1906 Thu May 2 11:22:02 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

1932 {unpack_,value_as_}long (for now anyway).
1934 * m88k-tdep.c (get_saved_register): Make get_reg a dc_word_t (*)().
1935 (psr_register): Change return type to dc_word_t.

1939 * m88k-tdep.c (get_saved_register): Add lvalp parameter.
1941 * gdbcore.h (write_memory): Don't prototype it.
1943 * tm-88k.h, m88k-tdep.c: Make stack_error, stack_jmp global.
1944 m88k-xdep.c: Don't mention stack_error.
1946 * {x,t}config/m88k ({X,T}DEPFILES): Add missing files.
1948 * mtrace.c: Don't typedef things like size_t, just #define them.
1950 * coffread.c [TDESC]: #if 0 out references to coffsyn.
1952 * symtab.h (struct symtab): Include EXTRA_SYMTAB_INFO.
1953 tm-88k.h: Define EXTRA_SYMTAB_INFO.
1955 * coffread.c [TDESC]: Include "tdesc.h" and make tdesc_handle
1956 dc_dcontext_t not int.
1958 * coffread.c [TDESC]: Use system include files not <intel-coff.h>.
1960 * coffread.c [TDESC]: Move setting of debug_info from
1961 coff_symfile_read to find_linenos and make it work with BFD.
1963 * cplus-dem.c [__STDC__]: Make x{m,re}alloc return void*.
1965 * signame.c: Cast const char* to char* when assigning to sys_siglist.
1967 * utils.c (strsave): Make arg const char* not char*.
1969 * infrun.c (wait_for_inferior) [SHIFT_INSN_REGS]: Use
1970 bpstat_explains_signal (stop_bpstat) not stop_breakpoint.

2455 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
2456 to the main file, as well as to include files. Also, put global
2457 functions into the global psymtab, to make "i fun" work.
2458 (end_psymtab): Free named symtabs and psymtabs for a file, once a
2459 new psymtab for it has been read.
2460 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
2461 a file, once a new symtab has been read for it.
2462 * mipsread.c: FIXME. We need to do the same for MIPS, but it
2463 looks harder to determine the top-level block before it's been
2464 queued to the psymtab list.
2466 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
2467 If we have wiped out any old symbol tables, clean up at end of
2469 (symbol_file_command): Don't reference symfile_fns if it's zero.
2471 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
2472 defines for the blocks of a blockvector that contain global and
2473 file-static symbols and the first of the smaller scope contours.
2474 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
2475 decode_line_1, make_symbol_completion_list): Use the above.
2476 * coffread.c (end_symtab, patch_opaque_types): Ditto.
2477 * dbxread.c (end_symtab): Ditto.
2478 * expread.y (block): Ditto.
2479 * mipsread.c (throughout): Ditto.
2480 * symmisc.c (free_named_symtabs): Ditto.
2482 * symtab.c (list_symbols): Process the first symbol of the
2483 static psymbols list.
2484 (types_info): Restore this function from its untimely #if 0.
2485 It's not perfect, but it is better than nothing.
2486 (_initialize_symtab): Restore "info types".
2488 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2490 * m68k-stub.c: Remote stub for 680x0's, created from
2491 rem-m68k.shar (which is removed).
2492 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
2493 Remove RCS log stuff now that we use CVS and it blows our diffs.
2495 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2497 * symmisc.c (free_named_symtab): Make it work, in its current
2498 kludgy fashion. Change result to indicate if we blew away bkpts.
2499 * dbxread.c (end_symtab): Accumulate result from
2500 free_named_symtab and print warning if we blew user's state.
2501 * symfile.h: free_named_symtab now returns an int.
2503 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
2505 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
2506 is the first symbol read, even if not mainline.
2507 (dbx_psymtab_to_symtab): symfile might be zero, cope.
2508 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
2509 (set_section_command): New command ("section xxx yyy" -- should
2510 be renamed to "set section xxx yyy" FIXME) which sets the
2511 base address of a section of the exec file, overriding the
2512 virtual address that BFD reports.
2514 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2516 * exec.c: Add add_syms_addr_command to exec_ops, so you can
2517 load symbols at any address while examining an exec file.
2519 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2521 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
2522 for printing the float info is host-dependent, not
2523 target-dependent. FIXME.
2524 * i386-pinsn.c: Move #includes to top, remove useless ones.
2525 * i386-tdep.c: Don't bother including <.../reg.h> since we
2526 don't use it (and it doesn't exist on host systems).
2528 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
2529 Convert negative numbers properly.
2530 (ieee_test): Make numbers really random; fix format arg.
2532 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
2533 * core.c (core_detach): Unpush core_ops, which might not be on
2534 top. We used to just pop the top, which broke things. Don't
2535 need dont_repeat() any more.
2536 (core_file_command): Psst! Don't repeat it.
2537 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
2538 * expprint.c (print_subexp): Avoid switch fallthru on
2539 BINOP_ASSIGN_MODIFY, so we can print += and such.
2540 * frame.h: Fix typo.
2541 * inflow.c (kill_command): After killing inferior, print our
2542 current frame in the core file, if we have one.
2543 (generic_mourn_inferior): When inferior dies, either select
2544 the current frame (in the new target, e.g. core file), or
2545 set both the current and selected frames to NULL.
2547 Changes from Peter Schauer.
2549 * infptrace.c: Avoid <sys/ptrace.h> on USG.
2551 * Make all file names fit in 14 characters (sigh and damn!):
2552 mv hp300hpux-xdep.c hp300ux-xdep.c
2553 mv symmetry-xdep.c symm-xdep.c
2554 mv symmetry-tdep.c symm-tdep.c
2555 mv convex-opcode.h convx-opcode.h
2556 mv tm-vxworks960.h tm-vx960.h
2557 mv tm-vxworks68.h tm-vx68.h
2558 mv Makefile.srcdir Makefile.sdir
2559 mv gdb-int.texinfo gdbint.texinfo
2560 mv remote-sa.m68k.shar rem-m68k.shar
2561 mv remote-multi.shar rem-multi.shar
2562 * Makefile.dist, README, config.gdb, convex-pinsn.c,
2563 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
2564 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
2567 * command.c (user_info_1, user_info): New command for listing
2568 the user-defined commands.
2570 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2572 * dbxread.c (really_free_pendings): Clear file_symbols
2573 and global_symbols after freeing them; otherwise, running
2574 this function twice (if it appears twice on the cleanup
2575 chain), we try to free things twice.
2577 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
2578 based on text_addr (the address of text in core), not on addr (the
2579 offset between text in the .o file and in core). This change
2580 is from Peter Schauer.
2582 * main.c: Define ALL_CLEANUPS as a cast of zero.
2583 (return_to_top_level): Use it.
2584 (main): Do all cleanups after each command run as part
2585 of the gdb startup sequence. Also do all cleanups before
2586 entering the command loop, and every time we exit the command
2587 loop and reenter. Before, the cleanups from the startup sequence
2588 were being left undone until the first error!
2589 (command_loop): Rename do_nothing cleanup to command_loop_marker
2590 so we can see it easily when examining the cleanup chain.
2591 (init_signals): Add another do_nothing for signal handling.
2592 (quit_command): Only try to kill target if it has execution.
2593 Problems in the target stack got us into a state where
2594 inferior_pid was nonzero but none of the targets had execution.
2595 In this state you couldn't exit gdb.
2597 * dbxread.c: Two changes from Peter Schauer.
2598 (echo_command): Fflush output after an echo command.
2599 (show_history): Pass all args to cmd_show_list.
2601 * utils.c (init_malloc): Call mtrace to turn on tracing
2602 if the environment variable MALLOC_TRACE is set to a file name.
2603 * mtrace.c: Add source file which provides a log of every malloc,
2604 free, and realloc to a trace file.
2605 * mtrace.awk: Add source file which analyzes the trace file.
2606 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
2607 (VERSION): Roll to 3.94.3.
2609 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
2610 (check_duplicates): Don't bother with watchpoints.
2611 (set_raw_breakpoint): Comment about danger of this routine.
2612 (watch_command): Parse and eval all args before calling
2615 * solib.c (find_solib): Avoid error in referencing memory to
2616 see if any more shared libraries have been added. This is
2617 particularly useful if the target has terminated. Bug reported
2620 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
2621 in bringing up 3.94.2 on the Sun-3.
2623 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
2624 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
2625 expression (in scope) before reenabling watchpoint.
2626 * signame.c (init_sigs): Add missing declaration of i, fix
2627 sys_siglist declaration.
2628 * source.c (list_command): Fixed range computation to use
2630 * stack.c (backtrace_command): Do not allow command if target has
2631 no stack, print informative error message.
2632 * target.c (target_command): Do not write into command line
2633 because this fails if the target command is used in a user defined
2634 command. [This change was enhanced by gnu to support any-
2635 unique-prefix matching on target names.]
2636 * valops.c (value_struct_elt): Avoid infinite loop on an
2637 erroneous attempt to print the member of function (try p main.p).
2639 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2641 * expread.y (name_no_typename): Avoid reduce/reduce errors
2642 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
2643 Since the GDB parser really doesn't use name_no_typename in a
2644 name-only context, the parser can't tell the diff between
2645 names and numbers here. Avoid allowing a name_no_typename
2646 to be a NAME_OR_*INT to resolve the conflict.
2648 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2650 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
2652 * valprint.c (val_print_fields): bitfield printing didn't handle
2653 byte order. Indirect through a few more fns to cope.
2655 * values.c (modify_field): also cope with byte order.
2657 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2659 Cleanup for release 3.94.2:
2661 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
2662 include files. Roll version to 3.94.2.
2664 * coffread.c (init_stringtab): Read length into unsigned char
2665 array before swapping; don't assume 32-bit longs.
2667 * target.c (target_info): Don't bother with get_sym_file, just use
2668 the symfile global variable.
2669 * symtab.h, symfile.c (get_sym_file): Delete it.
2671 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
2672 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
2673 (read_type): Replace one more error() with complain().
2675 * mipsread.c (parse_partial_symbols): Replace printf with complain.
2677 * i960-tdep.c: Fix copyright attribution.
2679 * config.gdb: Quote all backquotes in doublequotes. You can
2680 quote me on that. BSD 4.4 shell found this one.
2682 * infptrace.c (throughout): The third argument to ptrace is an
2685 * infrun.c (wait_for_inferior): When program has terminated, we
2686 have to call target_terminal_ours before we pop that target off
2687 the stack (e.g. before a call to target_kill or
2688 target_mourn_inferior). This fixes problem where a program
2689 terminates, then GDB stops for (tty output) and you have to type
2690 "fg" to the shell to resume it. FIXME: This code for what to
2691 do after termination really should be in normal_stop instead.
2693 * gdbcore.h (read_memory_check): Change declaration; it changed
2696 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
2697 4.4 prereleases, this avoids a bug in their sgtty compatability
2699 * remote.c: Use terminal.h rather than hand-rolling the same.
2701 * signame.c, signame.h (psignal): Arg is unsigned, not int.
2702 * utils.c (strsave, strstr): Fix arg types.
2703 * valprint.c (val_print): lint
2705 MIPS symbol table support from Per Bothner:
2707 * symfile.c (symtab_fns): Remove initializer table that needs to
2708 be hacked for each new symbol file format supported.
2709 (add_symtab_fns): New function, chains symbol table
2710 handlers into the global list.
2711 (symfile_init): Search this list.
2712 * symfile.h: Add next pointer, declare add_symtab_fns.
2713 * coffread.c (_initialize_coffread): Call add_symtab_fns.
2714 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
2716 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
2717 symbol *). Thus, we no longer need the hack to trash
2718 pst->filename. Good, since that hack confused code in symfile.c!
2720 (reorder_symtabs, destroy_all_symtabs): Removed static
2721 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
2722 Instead, the latter now uses a temporary array (stack-allocated
2723 from an obstack, and then freed).
2725 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
2726 haven't been set in the outermost stBlock of a procedure. This was
2727 a problem with f77 binaries on Ultrix 4.?.
2729 (new_symtab, new_symbol, new_type): Continue changing code to use
2730 obstacks more and otherwise conform to dbxread internal style.
2731 Made the free_code of symtabs be free_linetable (as in dbxread)
2732 instead of free_contents. This implies memory leaks when reading
2733 a new symbol table, until the conversion is finished. Did change
2734 (struct symbol) and (struct type) to be allocated on the
2735 symbol_obstack. Blocks and blockvectors are among the things
2738 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
2739 tested much, but it solved one problem (reported by Meissner), and
2740 cleans up some other things. The problem happened when an
2741 included file contains actual code (functions) and not just
2742 definitions. The mips coff is a little inconvenient there, since
2743 it may cause a procedure to be mapped to the wrong psymtab.
2745 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
2746 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
2747 this will need work for the new core paradigm.
2749 Opcode patches from the net:
2751 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
2752 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
2753 missing altogether - they are added here. From Bruce Bauman.
2754 * mips-opcode.h: The low mask for C0 instructions was too small.
2755 From Garrett Lau. I modified the fix to check the entire 32-bit
2758 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
2761 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2763 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
2765 * dbxread.c (read_type): Pointer subtraction (value_sub in
2766 valarith.c) sometimes failed because the types of the
2767 pointers being subtracted were not identical.
2768 These differed because dbxread.c was allocating pointer types
2769 using dbx_alloc_type+smash_to_pointer_type instead of
2770 lookup_pointer_type. I failed to find a justification for the
2771 former, so I changed it to use the latter. Similarly, I
2772 replaced smash_to_function_type by lookup_function_type,
2773 and smash_to_reference_type by lookup_reference_type.
2775 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
2776 _initialize_mipsread): corresponding changes.
2778 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
2780 * source.c (mod_path): Do tilde_expand on each component of the path,
2781 rather than on the (list of) paths as a whole.
2782 (print_source_lines): Set first_line_listed in addition to
2783 current_source_symtab and current_source_line. If the source was
2784 not findable, after a "dir" command to fix the problem,
2785 a "list" would get the wrong lines.
2787 While I was there... (gnu):
2789 * dbxread.c (read_type): Change error to complaint.
2791 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2793 First attempt at detailed understanding of symbol table memory alloc.
2795 * dbxread.c (dbx_symfile_read): Free our string table if we
2796 aren't the mainline. Free the "info" struct since we're done with
2798 (init_psymbol_list): Free any previously allocated psymbol lists.
2799 (): FIXME: Should realloc-down the psymbol lists when done reading
2800 the main symbol file?
2802 * symmisc.c (free_symtab): Free fullname field too.
2804 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
2805 (REGISTER_ADDR): Make result type unsigned int.
2807 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
2808 define REGEX must also define REGEX1 (its dependency).
2810 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2812 * tconfig/i960: No longer works, points you at vxworks960 or
2815 * xgdb.c, XGDB-README: Remove file. Users can get the much
2817 * Makefile.dist: Remove all trace of xgdb.
2819 * breakpoint.c (breakpoint_1): Pass demangle arg to
2820 print_address_symbolic.
2821 (clear_breakpoints): Remove unused function.
2822 (breakpoint_re_set_one): Guts of breakpoint_re_set.
2823 (breakpoint_re_set): Use catch_errors to do them all anyway.
2825 * gdb-int.texinfo (Host versus Target): Add section on what is
2826 a "host" feature versus what is a "target" feature.
2828 * infcmd.c (path_command, path_info): Handle the PATH variable
2829 (object search path) as conveniently as the source search path.
2830 * environ.c (set_in_environ): Set some vars in GDB's environment,
2831 in addition to the child's. PATH, G960BASE, G960BIN for starters.
2832 * source.c (mod_path): New function, from guts of
2833 directory_command, modifies a path. Used by path_command.
2834 (directory_command): Call it.
2835 * defs.h (strsave): Declare.
2837 * utils.c (sevenbit_strings): Add new printing option.
2838 (printchar): Use it.
2839 (strsave): Provide this handy helper routine.
2840 (set_width_command): Rename set_screen_width_command.
2841 (_initialize_utils): "set screen-width" => "set width";
2842 "set screen-height" => "set height"; add sevenbit-strings.
2844 * infcmd.c (do_registers_info): Print floating point registers
2845 in raw hex as well as float format, regardless of whether it is
2846 a "virtual" convertible register.
2847 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
2848 regs as a double, just in case it's being used that way.
2849 * values.c (unpack_long): Comment on array/function coercion.
2850 (unpack_double): Argument is in target byte order now. For
2851 integer arguments, just call unpack_long and float the result.
2852 * m68k-tdep.c: include defs.h for "const" handling.
2853 * remote-nindy.c: Use ieee-float stuff.
2854 (nindy_fetch_registers): Unpack double regs to host double, then
2856 (nindy_store_registers): Pack extendeds to host double, flip
2857 around by misusing unpack_double, send as target double.
2859 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
2860 zero, as when stopped at the first instruction of a process.
2862 * blockframe.c: Fix filename in comment (param.h => tm.h).
2863 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
2864 * tm-68k.h: Fix typos.
2866 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
2868 Changes from a bringup on the DEC Vax under Ultrix 4.0.
2870 * coredep.c (fetch_core_registers): Pass end-address of register
2871 section to register_addr as expected. Don't call supply_register
2872 if we'd just pass it garbage.
2874 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
2876 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
2878 * target.c (push_target, target_info): Cast enums to int for < or
2881 * stack.c (print_frame_info): Identify source file & line
2882 even if we can't print it.
2884 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
2886 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
2888 Clean up IEEE floating point support.
2890 * ieee-float.h: New file.
2891 * ieee-float.c: Write real routines to convert between host
2892 doubles and various target IEEE extendeds.
2893 * m68k-xdep.c: Eliminate assembler code for extended floats.
2894 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
2895 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
2896 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
2897 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
2898 double_to_ieee_extended.
2899 * i960-tdep.c: Define ext_format_i960.
2900 * m68k-tdep.c: Define ext_format_68881.
2901 * sparc-tdep.c: Define ext_format_sparc, though unused.
2902 * Makefile.dist (HFILES): Add ieee-float.h.
2903 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
2906 Obsolete the "coffstrip" program in favor of using BFD's strip.
2908 * nindy-share/coffstrip.c: Remove file.
2909 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
2910 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
2911 * tconfig/nindy960: Remove reference to coffstrip.o.
2913 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
2915 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2917 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
2918 * dbxread.c: Remove static symfile_bfd.
2919 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
2921 * inftarg.c (child_detach): Pop the child_ops vector if the
2922 detach is successful.
2923 * remote-nindy.c (nindy_create_inferior): Don't push a new
2924 nindy_ops since nindy uses the same one for execution and memory
2926 * core.c (core_ops): Use child_attach and child_create_inferior
2927 rather than default attach and create_inferior functions.
2929 Handle floating point registers in core files.
2931 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
2932 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
2933 This version untested since BFD doesn't yet support sun3 core
2935 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
2936 conventions. Fix comments and style. This version has not
2937 been compiled yet, since we have no HP inhouse.
2938 * core.c (get_core_registers): Look for two sections, ".reg"
2939 and ".reg2", and pass both to fetch_core_registers sequentially.
2941 Revise directory path yet again.
2943 * source.c (forget_cached_source_info): Not static any more.
2944 (init_source_path): New default source path is "$cdir:$cwd".
2945 (dir_command): Handle variable arguments ($cdir, $cwd).
2946 (source_info): Print "Compilation directory" rather than
2947 "Originally compiled in" to remind people of $cdir.
2948 (openp): If the path contains $cwd, use current directory.
2949 (open_source_file): If compilation directory is known, replace
2950 first $cdir in path with the compilation directory.
2951 (print_source_lines): Even if we can't print the lines, set the
2952 current symtab and line for future commands like "info source" or
2953 "breakpoint". Also, error message now contains the file name,
2954 line number, and file access error message.
2955 (_initialize_source): Fix help text to describe changes.
2956 * main.c (cd_command): Forget cached source info when we chdir.
2957 * utils.c (strstr): Add simple implementation.
2959 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
2961 * coffread.c (read_one_sym, init_linetable, init_stringtab):
2962 Byte-swap COFF symbol tables if necessary when reading them in.
2963 Use complain() to replace error message in one spot. Needs
2964 corresponding change in bfd/coff-code.h to make some symbol
2965 swapping routines non-static.
2967 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
2969 Merge changes from Eirik Fuller, for UTek.
2971 * defs.h (errno): Add declaration.
2972 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
2973 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
2974 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
2975 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
2976 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
2977 declarations of errno.
2979 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
2981 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
2982 <rpc/rpc.h> and <rpc/types.h>.
2984 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
2986 * i960-tdep.c (examine_prologue): Add new argument limit,
2987 which stops the scan at the end of the prologue, or at the PC.
2988 This fixes a problem where it walks down into the code for the
2989 user's statements if that code looks like function prologues.
2990 Mark Fox and I have been bouncing this code back and forth, making
2991 small changes to it. Callers changed to match.
2993 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
2995 Cleanup for gdb-3.94 release final:
2997 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
2998 the .c files from vx-share and nindy-share, from the various
2999 macros, since they are not found via ALLDEPFILES.
3000 (SFILES): Add tm-i960.h.
3001 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3002 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3004 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3005 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
3007 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
3009 * am29k-tdep.c: Add contribution line.
3010 (examine_prologue): Cache information about function prologues in
3011 the misc-function-vector to avoid lots of references over the
3012 serial line while examining instructions.
3014 * core.c (core_close): New function made from cleanup_core.
3016 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3017 remote-vx.c, remote.c, target.c, target.h,
3018 Update target_ops vector to add attach, close, and load entries.
3019 Use add_syms_addr_command, not add_file_addr_command, for
3020 add_file. Break out close routine from existing code.
3022 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3023 they are in an obstack.
3024 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3026 (define_symbol): Add symbol type parameter; change callers;
3027 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3028 it to influence the symbol class on the i960.
3029 (define_symbol): Swap LOC_CONST's into target byte order.
3031 * exec.c (exec_close): New function.
3032 (exec_file_command): Call it.
3034 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3035 Fix byte order of frame pointer.
3036 (read_var_value): Result of 0 if var's value can't be found,
3037 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3038 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3039 (locate_var_value): Use read_var_value and use its lazy address
3040 as the location of the var's value. Lint.
3042 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3045 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3046 obsolete Intel versions in favor of vxgdb versions.
3047 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3048 code dealing with byte order of values, which Intel did in host byte
3049 order rather than gdb-4's target byte order.
3050 (i960_frame_chain_valid): Move to nindy-tdep.c.
3051 (examine_prologue, skip_prologue, frame_find_saved_regs,
3052 frame_args_address, leafproc_return, saved_pc_after_call,
3053 pop_frame): Add vxgdb versions from Mark Fox.
3054 (examine_prologue, frame_struct_result_address): Add code
3055 to deal with the saved value of G13 (struct return address
3057 (frame_args_address): Modify Mark's version to prefer the
3058 saved value over the current value in the topmost frame.
3059 Cache result in the frame info to avoid performance hair in
3061 (print_fault): Add gdb960 code for printing faults.
3062 (_initialize_i960): Actually call check_host.
3064 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3065 add stub routines. FIXME, these currently just return zero!
3067 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3068 (attach_command): Call target_attach, not target_open, now.
3070 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3071 (child_attach): Rename from child_open.
3072 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3073 don't confuse it with a zero step_resume_break_address.
3075 * inftarg.c (child_detach): Eliminate inferior_pid test.
3076 (child_files_info): Clean up message a bit.
3077 (child_ops): Use child_attach, not child_open, to attach.
3079 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3080 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3081 findvar.c to here, since it depends on the contents of the
3082 shadow_contents of breakpoints, but keep if #if 0 since it is
3085 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3088 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3089 (ptype_command, display_command): Eliminate have_inferior_p and
3090 have_core_file_p in favor of target_has_stack or
3091 target_has_execution.
3092 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3093 code for actually finding the values of arguments, though we still
3094 keep track of the maximum stack offset for use in printing unnamed
3095 arguments. Handle missing FRAME_ARGS_ADDRESS.
3097 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3098 (struct nindy_regs): Define registers passed to/from nindy.
3099 (nindy_fetch_registers, nindy_store-registers): Translate between
3100 nindy and GDB formats for the registers.
3101 (dcache_init): Statically allocate the cache, since it was being
3102 allocated by a malloc that was never freed anyway.
3103 (nindy_create_inferior): Error, not core dump, if no exec file.
3104 (nindy_before_main_loop): Use target_load, not target_add_file.
3106 * remote-vx.c (net_load): Specify large timeout for load
3107 requests. Allow user to break out with INTERRUPT.
3108 (net_break): Remove useless code, clean up. Change callers.
3109 (parse-args, skip_white_space, find_white_space): Clean up arg
3110 parsing to cope with quoted strings.
3111 (net_wait, net_quit): Never call error, just return status.
3112 (vx_read_register, vx_write_register): Cleanup status checking.
3113 #ifdef the code based on which CPU we are using (960 or 68k),
3114 FIXME, this should be completely general but it isn't yet.
3115 (vx_xfer_memory, vx_resume): Cleanup status checking.
3116 (vx_run_files_info): Improve message.
3117 (vx_load_command): Renamed from vx_add_file_command. Allow load
3119 (net_ptrace): Remove unused routine.
3120 (vx_wait): Adopt code from vxgdb960 to cope with broken
3121 connections to target machine and prompt to disconnect. Remove
3122 debug printouts. Map some EVENT_'s to SIGnals.
3123 (add_symbol_stub, vx_open): Print names of object files we found,
3124 and "ok" if we read their symbols OK. Clarify output in general.
3125 (vx_attach, vx_detach, vx_kill): Add these commands.
3126 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3127 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3128 "info files" output, and create_inferior, since we already have
3131 * stack.c (frame_info): Replace Frame_unknown with 0.
3132 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3133 (return_command): Pop until the PC matches as well as the FP,
3134 so it works even if the FP is shared with another function,
3135 as in "frameless" or "leaf" procedures.
3137 * symfile.c (load_command): renamed from add_file_target_command.
3138 (add_syms_addr_command): renamed from add_file_addr_command.
3139 (add_syms_command): Stub to call target_add_syms.
3140 (_initialize_symfile): Change command names and descriptions,
3141 add-file => add-syms, and load from alias to its own command.
3143 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3144 maybe_kill_then_create_inferior): Default for attempts to start
3145 a process, if one is already running, is to ask about killing
3146 it and retry if yes.
3147 (upstack_create_inferior): #if-0 it, strata obsolete it.
3148 (push_target, unpush_target, pop_target): to_close() a target
3149 before unstacking it.
3150 (target_info): Renamed from target_files_info.
3151 (_initialize_targets): Rename "i files" as "i target", accessible
3154 * target.h: Improve comments about the target_ vectored routines.
3156 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3157 Convert commenting style to standard GNU style.
3158 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3159 (SKIP_PROLOGUE): No longer a no-op.
3160 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3161 (*_REGNUM): Sort register numbers.
3162 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3163 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3164 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3165 are now 10 byte extendeds, not 8 byte doubles.
3166 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3167 for nindy versus vxworks targets. FIXME, this should possibly go
3168 in the target vector.
3169 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3170 frame_saved_regs and arg pointer with each frame.
3171 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3172 (FRAME_ARGS_ADDRESS): Use cached result.
3173 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3174 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3175 (PRINT_RAMDON_SIGNAL): Call print_fault.
3176 (POP_FRAME): Now works.
3178 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3179 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3180 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3181 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3184 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3185 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3187 * valarith.c (value_subscripted_rvalue): Avoid handling
3188 floats and doubles specially; it gave alignment errors. Lint.
3190 * valops.c (value_of_variable, value_of_this): Error if unknown
3193 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3194 to avoid alignment problems.
3195 (value_print): Handle unknown value address.
3196 (cplus_val_print): Two args are ignored; remove them. Change caller.
3197 (val_print): Use unpack_long rather than pointer-deref.
3200 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3201 to avoid alignment problems.
3202 (value_being_returned): Error if return value unknown.
3203 (set_return_value): Add bogosity warning, FIXME. *
3205 * TODO: A woman's work is never done.
3207 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3208 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3209 Add ieee-float.o to OBS.
3210 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3211 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3212 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3214 Changes to generalize the VxWorks RPC protocol slightly, to handle
3215 i960 as well as 68000.
3217 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3218 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3219 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3220 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3221 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3222 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3223 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3224 so they will move in target byte order rather than network
3225 byte order (happens to be the same).
3227 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3229 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3231 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3234 Add contribution lines to various files, showing where they
3237 * breakpoint.c (break_insn, check_break_insn_size,
3238 read_memory_nobpt): Remove to mem-break.c.
3240 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3243 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3244 entry has bad register number. This change is not
3245 tested in this release, FIXME.
3247 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3250 * value.h: Force value's contents field to be aligned to hold
3251 at least a double or a long long (if supported). This avoids
3252 doing bcopy's in and out of the contents field.
3254 (step_1): Avoid coredump under obscure circumstances when we
3257 * symtab.h (misc_info): Add field to misc function vector for
3258 any kind of cached information the target code desires. AMD
3259 29000 uses this to avoid repeating examine_function_prologue's.
3261 * coffread.c: Lint. Remove static symfile, read_section_header.
3262 core.c (have_core_file_p): Lint: remove.
3263 expprint.c (print_subexp): Lint.
3264 infptrace.c, valops.c, valprint.c: lint.
3266 Roll in changes from vxgdb-5.0.1:
3268 * symtab.h: Comment byte order of each address class. Add
3269 LOC_LOCAL_ARG for frame-relative args (960).
3270 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3271 symtab.c, symmisc.c: ditto.
3273 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3275 * remote.c (remote_resume): Error if resume with a signal.
3277 * symfile.c (prim_record_misc_function): Clear misc_info.
3278 (fill_in_vptr_fieldno): Check stub type of arg.
3280 * valops.c (value_cast): Avoid looking up names of types whose
3281 name we don't know, to prevent coredump. Sun CC produces typedef
3282 rtx and the name of *rtx is zero...
3284 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3286 Roll in changes from final AMD 29000 port (Tiemann).
3288 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3289 for ../include/a.out.encap.h. This might not work now that BFD
3290 is separately compiled. Instead, BFD support for encap will have
3291 to translate machine type 29k into the right COFF_MAGIC.
3293 * infcmd.c: Remove references to inferior_pid that aren't used
3294 in actual ptrace calls; use target_has_execution, etc.
3295 (have_inferior_p): Remove function.
3296 (program_info): Print target info rather than "process number";
3297 avoid gratuitous messages unless from_tty.
3298 (run_stack_dummy, finish_command): Set proceed_to_finish.
3299 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3300 main.c: Lint. Lose have_inferior_p().
3301 inferior.h (have_inferior_p): Remove, lint.
3302 (proceed_to_finish): Add flag to ask that all regs be saved
3303 by normal_stop, for the few commands that need it, speeding up
3304 serial I/O. Add comments to stop_registers.
3306 * remote-eb.c: Remove newline from breakpoint message we grep
3307 for. Never time out when running the user program.
3311 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3313 Roll in changes from vxgdb-5.0.1:
3315 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3316 symbol in its raw form, we are processing an unlinked ".o" file.
3317 See if the target environment has assigned it an address, using
3318 target_lookup_symbol (VxWorks does), and enter it into the symtab
3321 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3322 68k versions for a simpler version that assumes zero FP at bottom.
3323 Fixes bug of truncated stack reports.
3325 * target.h (target_lookup_symbol): Define this routine's args
3326 and result, finally.
3328 * target.c (nosymbol): Default routine for target_lookup_symbol.
3329 (target_default): Default lookup_symbol and call_function too.
3330 (files_info): Only print has_all_memory warning if a non-dummy
3333 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3334 vx_convert_from_virtual): If target does not have floating point,
3335 zero register "values", and avoid doing cross-net conversions.
3336 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3337 (vx_open): Rearrange code that attaches to target and reads
3338 symbols for all loaded modules, to work if some of the modules
3339 are not accessible. Add symbol_stub() and add_symbol_stub()
3340 as callbacks from catch_errors(). Allow connect attempt to be
3341 interrupted painlessly with ^C (FIXME, there are still some bugs
3342 if the interrupt happens during symbol reading.). Print
3343 final message with puts_filtered, since symbol messages are
3348 * main.c (catch_errors): Only print errstring if non-null.
3349 (command_loop): Avoid an ioctl per command to test ISATTY.
3351 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3352 (vx_xfer_memory): Return correct result!
3353 (vx_files_info): Indicate whether target has float or not.
3354 (vx_lookup_symbol): Complain, not error, if target gone.
3355 (vx_open): Print "Connected" msg before disabling immediate-quit.
3356 [FIXME: lookup_symbol and vx_open changes need testing.]
3358 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3359 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3360 contributor lines and update copyrights to 1991.
3362 Changes from an attempted H-PUX host port:
3364 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3365 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3366 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3367 * remote-vx.c: include <sys/time.h> for HPUX.
3368 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3369 "core_file_command" routine to BFD regime. May not work yet.
3371 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3373 * xgdb.c: Replace X10 version with some VJ version.
3374 (FIXME: Its copyright assignment is not on record.)
3375 * xgdb.c: Update include files to X11R4 (Xaw crud).
3376 (xgdb_display_source, create_text_widget): fix call to
3377 get_filename_and_charpos. Rewack source window stuff for X11R4
3378 (gleaned from include files, and "nm's" of binary libraries, since
3379 I had no doc available).
3380 (append_selection, append_selection_word): Disable with FIXME
3381 since R4 changed interface here.
3382 (create_buttons): Add back the old set of buttons.
3383 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3385 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3386 Roll VERSION to 3.94 (not yet final though).
3388 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3390 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3391 obstack_int_grow, obstack_int_grow_fast): Eliminate
3392 cast on left of assignment, which gives MIPS cc fits and is
3395 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3396 F_ALIAS. Use printf, not fprintf, when not passing a file
3398 (compare_opcodes): Check that identical instructions have
3399 identical opcodes, complain otherwise.
3401 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3402 was reported by Roland McGrath.
3403 (unimp): Only match if exactly zero instruction. (Roland)
3404 (branches and traps): Generate all variations of these
3405 instructions with macros, based on a single call that defines
3406 each condition name and its binary representation.
3407 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3409 * valprint.c (val_print_fields): Take, and use, format parameter.
3410 This means that "p/x struct" again prints the elements in the
3411 desired format. Changed callers.
3413 * stack.c (frame_info): Use filtered output, and indicate wrap
3414 points. Remove kludgy formatting designed to avoid line wrap.
3416 * utils.c (wrap_here): If the line is already full (because
3417 we had printed a long indent or long wrapped string), do an
3418 immediate newline-and-indent.
3420 * m68k-pinsn.c (print_insn_arg): Bugfix from
3421 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3422 instruction is incorrectly disassembled as bkpt #8.
3424 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3425 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3426 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3427 and then will dump core (sometimes). I traced it back to an
3428 uninitialized symfile_name in psymtab_to_symtab.
3429 (const_vol_complaint): Add quotes to message.
3430 (define_symbol): Only believe line number if gcc_compiled.
3431 Avoid allocating symbol if we will not return it.
3433 Add target strata support so that newly established targets go
3434 into their right place in the target stack (e.g. a new exec file
3435 doesn't wipe out the ability to access the running process).
3437 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3438 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3439 and initialize it properly in all the targets.
3441 * target.h: Document strata. Change return type of push_target.
3443 * target.c (nomemory): new function for dummy memory access.
3444 (tcomplain): Rename complain, now also used in symfile.c.
3445 (push_target): Push targets within strata. New return value shows
3446 whether new target is on top of stack or not. Always keep dummy
3448 (target_files_info): Ignore dummy target.
3450 * core.c (core_open): Warn user, and skip accessing file, if the
3451 core target is not the topmost target in the stack.
3452 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3455 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3456 target_ops, it doesn't belong there since we have no regs there.
3457 Change name of target from machine => memory to clarify.
3459 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3461 * Freeze version 3.93 for release.
3463 * Makefile.dist: Handle vx-share and nindy-share subdirs
3464 properly when building gdb.tar.Z.
3466 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3467 printed in various places, so I could change just one copy.
3469 * dbxread.c, coffread.c: Change references to bfd->iostream
3470 to cast to FILE *, now that BFD avoids needing types defined
3471 in other header files.
3473 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3475 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3476 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3477 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3478 (actually gcc -Wall).
3480 * dbxread.c: Remove first_global_sym, last_global_sym, since
3481 they are never referenced.
3483 * defs.h (baud_rate): Declare.
3484 main.c: Define it, and add the -b option to set it.
3486 * gdb-int.texinfo: Add text on how to define a new host or target
3487 architecture, prompted by Per Bothner's questions about MIPS
3490 * gdb.texinfo: Document "complaints". Change doc of -q since
3491 gdb no longer prints the copyright and blurb if you specify a file
3492 name to be debugged (just like Emacs). Add doc for Nindy-specific
3493 command line flags for specifying target serial port and such.
3494 Update copyright to 1991.
3496 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3497 has taken over for us the job of ripping up executable files. The
3498 crud caused Per Bothner's port to not compile.
3500 * infrun.c (normal_stop): Avoid printing "Program exited
3501 normally" if we are in batch mode. This allows a GDB which
3502 executes a program on a target system, to behave like a Unix
3503 command (input from stdin, output to stdout, no extraneous
3506 * main.c (main): Allow additional machine-dependent command line
3507 options to be specified with the ADDITIONAL_OPTIONS,
3508 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3509 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3510 processing to occur just before the main loop with
3511 BEFORE_MAIN_LOOP_HOOK.
3512 (main): If a "core file" argument is specified, and it is not a
3513 core file, try it as a process ID to attach.
3514 (symbol_completion_function): Attempt to cope with
3515 "show screen-" TAB, not very successfully. This needs more work,
3517 (batch_file): New function, returns whether we are reading
3518 commands from an interactive tty on stdin, or from somewhere else.
3519 Called by normal_stop since it doesn't get from_tty passed down
3520 to it like many commands do.
3522 * remote-nindy.c: Handle command line options for nindy
3524 (nindy_before_main_loop): Prompt user for tty name if they
3525 don't specify it before getting to the interactive command loop.
3527 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3528 and -r command line options. Also add hook before main loop
3529 to make it easy to specify a tty.
3531 * TODO: More things to do, one done.
3533 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3535 * dbxread.c: Make complaint() calls pass pointer, not struct.
3536 Add complaints about badly formatted C++ type information
3537 (const/volatile indicator, and parse errors resulting in
3538 error_type). Fix C++ virtual member fn comment.
3539 (read_struct_type): Avoid bumping pointer if we got a parse
3540 error; this prevents our walking beyond the end of a string.
3541 Terminate loop on null char as well as semicolon.
3542 (process_one_symbol): Fix the LBRAC fix so that it uses the
3543 last previous SLINE, FUN, or SO record's PC address. C++ debug
3544 symbols did not have SLINE records in a useful order compared
3545 to the LBRAC records.
3546 (define_symbol): Handle "catch" records.
3548 * symtab.c (check_stub_type): Added new complain
3549 `stub_noname_complain' and added a consistency check to
3550 keep the debugger from crashing when finishing from an
3551 exception frame. A real fix will be needed later.
3553 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3555 * infcmd.c (attach_command): Make global.
3557 * Makefile.dist (REMOTE_OBS): Make these compile by default,
3558 but make them easy to comment out. Perhaps later they should
3559 be enabled by what CPU you configure for? FIXME.
3560 (VERSION): Roll to 3.93.
3561 (pinsn.o): Remove rule for obsolete file.
3562 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
3564 Run down a problem that manifested by printing the wrong function
3565 name in stack traces of read_ofile_symtab. Turned out that the
3566 problem was the SunOS 4.1.1 (and previous) C compiler outputs
3567 the LBRAC symbol with an address in the *data* segment, which
3568 blew our binary search through the blocks.
3570 * dbxread.c: Use the complain() facility consistently to bitch
3571 about problems in the symbol file we are reading.
3572 (finish_block): Add code to check the nesting of the blocks;
3573 complain and Procrust them to fit if wrong.
3574 (make_blockvector): Check the order of the blocks, complain
3575 [but don't cope] if wrong.
3576 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
3577 symbols to be sure their PC value is greater than the last SLINE
3578 (line number) symbol we've seen, complaining and adopting the
3579 SLINE PC value if wrong.
3581 * symfile.h (struct complaint, complaint_root, complain,
3582 clear_complaints): Add.
3583 * symfile.c (complain, complaint_root, clear_complaints): Add
3584 facility to deal with non-fatal complaints and to regularize their
3586 (symbol_file_add): Clear complaint counters to allow new complaints.
3587 (initialize_symfile): Add 'set complaints' and 'show complaints'.
3589 * dbxread.c (dbx_symfile_read): Remember the address and size
3590 of the string table for the main symbol file, so we won't read it
3592 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
3593 to avoid reading the string table yet again. Lint.
3594 (throughout): Improve filtered output, including word wrap.
3595 (read_range_type): Improve Bothner's fix to handle other types too.
3597 * utils.c: Improve line wrap implementation. Handle unlimited
3598 width by making chars_per_line unsigned.
3599 (puts_filtered): New, easy, function.
3601 * defs.h (puts_filtered): add.
3603 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
3604 call the identical sort_symtab_syms() in symfile.c instead.
3606 * expread.y: Suggest the `file' command rather than `symbol-file'.
3608 * command.h (enum var_types): Add zinteger for seroable
3610 * command.c (do_setshow_command): Handle var_zinteger. Restructure
3611 nested if's into a switch.
3613 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
3614 we did not stop because of a breakpoint (it must have been for
3615 some other reason, like a "stepi"), so don't print anything.
3617 * symtab.c: Include <sys/types.h> all the time. Now that BFD
3618 doesn't include <sys/types.h>, old SunOS's require it for
3621 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
3623 A test port of gdb-3.92.6 to the Sony NEWS.
3626 Don't normally link in remote- or vx stuff.
3627 Some of it doesn't compile, and it wastes space for 99% of the users.
3628 Remove reference to no-longer-used HAVE_VPRINTF.
3629 Fixed BFD_DEP typo to BFD_DIR.
3631 Fix cast in arg to bfd_h_getlong.
3632 Make char *prefix be const.
3633 Fix how certain range types are mapped into builtin unsigned int types.
3635 Remove 2 #includes. They cause errors (on Sony, at least),
3636 and aren't needed (they wern't in earlier versions).
3638 print_address_symbolic should never demangle labels
3639 (since it prints *assembler-level* labels).
3641 [This was superseded by the change to printcmd below.]
3644 Add some "volatile" return types to avoid warnings.
3645 If MISSING_VPRINTF add vprintf function and not just macro
3646 (since vprintf is used in printcmd.c).
3648 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
3649 (The latter isn't grokked by some PCC-based compilers.)
3651 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
3653 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
3654 * nindy-share/coffstrip.c
3655 Added some forward declarations (otherwise, gcc complains
3656 about implicit extern redefined as static).
3658 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3660 Changes inspired by Per Bothner:
3661 * printcmd.c (print_address_symbolic): Take additional parameter
3662 specifying whether to demangle.
3663 (print_address): Pass in asm_demangle to control demangling.
3664 (print_address_demangle): New fn, takes explicit arg to control
3666 * utils.c: Add new vars demangle and asm_demangle, and let them
3668 (fputs_demangled): If !demangle, just print the argument.
3669 (fprint_symbol): If !demangle, just print raw symbol.
3670 * valprint.c (val_print): Call print_address_demangle rather than
3671 print_address, to cause demangling to depend on the global
3672 rather than assembler-level demangling setting.
3673 * WHATS.NEW, gdb.texinfo: Document.
3675 * main.c (show_command): Show all settings if no arg.
3676 (initialize_main): Make "info set" the same as naked "show".
3677 * command.c (cmd_show_list): Handle prefix commands in the
3678 list, and print the name of the setting as well as its English
3679 description and value.
3681 Allow gdb functions to specify where a line should wrap if it
3682 exceeds the size of a terminal line. Use it to make the output
3684 * utils.c (set_screen_width_command): New fn, mallocs a buffer
3685 of the right size when screen width changes.
3686 (set_screensize_command, screensize_info): Remove #if 0'd fns.
3687 (wrap_here): New fn, indicates a point in the output where we
3688 should wrap the line rather than just letting it overflow at a
3690 (fputs_filtered): Implement wrapping.
3691 (n_spaces): New fn, returns a pointer to N spaces.
3692 (print_spaces_filtered): Use n_spaces.
3693 * defs.h (n_spaces): Declare.
3694 * stack.c (print_frame_info): Wrap with 4-space indent after
3695 fn name and before filename and line number.
3696 * printcmd.c (print_frame_args): Wrap with 4-space indent
3697 before each argument name is printed.
3698 * valprint.c (value_print): Wrap with no indentation before
3700 (val_print_fields): Wrap with indentation relative to nesting
3701 level before each field name.
3702 (val_print): Wrap with nesting indentation before array elements.
3703 * command.c (do_setshow_command): Avoid extra newlines,
3704 wrap with 4-space indent around values printed, end with period.
3705 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
3707 * breakpoint.c (breakpoint_1): Implement addressprint for
3708 "info breakpoints" display. Change file name and line number
3709 format to " at file:nnn" rather than " (file line nnn)".
3710 * gdb.texinfo: Document.
3713 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3715 Frozen for gdb-3.92.6 release.
3717 README, WHATS.NEW: Update for 3.92.6 release.
3719 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
3720 coffread.o from configs since it is now built by default.
3721 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
3722 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
3723 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
3724 from configs since it is now built by default.
3726 Makefile.dist: Update for release 3.92.6. Handle files that
3727 have been moved to ../include, ../getopt, or ../bfd. Add
3728 saber.suppress and tests directory. Add config.status to
3729 the release (it will say "none").
3731 coredep.c: Minor formatting fixes.
3733 These changes were made in early December but only checked in now:
3734 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
3735 nindy-share/nindy.c: lint
3736 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
3737 register values coming back from the target; we store values
3738 in target byte order everywhere.
3740 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
3742 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
3744 * valprint.c (cplus_val_print, val_print_fields): New functions,
3745 which print C++ objects. They conspire to avoid printing a
3746 virtual base class more than once, following all the twists and
3747 turns of C++ virtual base rules.
3748 (val_print): Call the above rather than do it by hand.
3750 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
3751 symbol file, not for added files like shared libs. This really
3752 needs to be generalized to a timestamp per file.
3754 * core.c (cleanup_core): Avoid coredump if no core file.
3756 * config.gdb: Accept -host or -target in place of +host or
3759 * coffread.c (find_linenos): Avoid desupported BFD interface
3760 to line numbers. We still read them manually rather than using
3761 BFD's "generic" features.
3763 * gdbrc.tex, threecol.tex: Add GDB reference card and its
3765 Makefile.dist: Add refcard to OTHERS list for creating tar files.
3767 * Makefile.dist: Eliminate use of $< in explicit targets.
3769 * readline/Makefile: Use $< rather than $*.c, which does not
3770 include the VPATH in GNU Make.
3772 * tconfig/i960-bout, tconfig/i960-coff: These are identical
3773 copies of tconfig/i960, added for global configuration
3774 compatability. All i960 versions can read both coff and b.out.
3776 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
3777 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
3780 * TODO: Think of more things to do.
3782 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
3784 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
3785 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
3786 64-bit float conversion.
3788 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
3789 equivalent to sun?os4 so global config works.
3791 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
3793 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
3795 * main.c: Only declare linesize once; declare pagesize not at
3796 all, since it is never used.
3797 (main): Clear newly allocated line before it is used.
3799 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
3801 Further stabilization for the Intel 960.
3803 * Makefile.dist: Parameterize the location of the "include"
3804 and "bfd" directories, as well as "getopt". Add symfile.c.
3805 Link in both dbxread and coffread. Fix up "make depend" to
3806 rewack the locations of include, bfd, and getopt in its output.
3808 * README: Document moving include files, improve some of
3811 * coffread.c: Move common code out to symfile.c. Change
3812 symbol_file_command style interface to use new *_symfile_init
3813 and *_symfile_read interface under BFD. Use BFD internal
3814 info to locate line table, symbols, etc.
3816 * core.c (core_fetch_registers): Rename to get_core_registers
3817 to avoid confusion with fetch_core_registers.
3818 (register_addr): Move to coredep.c, which is already machine
3819 dependent. This leaves core.c pretty clean of dependencies.
3821 * coredep.c (register_addr): Accept this routine from core.c.
3823 * dbxread.c: Move common code (with coffread.c, etc) into new
3824 symfile.c. Each psymtab now contains a pointer to the
3825 format-dependent function that knows how to read it in. Make
3827 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
3828 (process_one_symbol): Add code to complain about a "compiler bug
3829 we muzzle here", if we actually see it.
3831 * eval.c (evaluate_subexp): Insert missing "break" statements
3832 in code that determines whether a variable is an lvalue in
3833 memory, register, or whatever. I detected this via a compiler
3834 bug in which it *almost* mashed out the whole switch statement.
3836 * gdb-int.texinfo: Add minor sections on configuring gdb for
3837 release, and about the README file.
3839 * infcmd.c (registers_info): Fix formatting somewhat. Still
3840 not as pretty as before, but it handles byte swapping.
3842 * remote-nindy.c: If data cache routines are interrupted while
3843 waiting for the remote end, be sure that any uninitialized cache
3844 blocks are on the free list, not on the valid list!
3846 * symfile.h: Flesh out this header file with all the various
3847 routines and variables that have been merged in from dbxread.c
3848 coffread.c, and symtab.c to symfile.c.
3850 * symfile.c: New file, containing code common to dbxread.c,
3851 coffread.c, and some code from symtab.c. All generic code for
3852 reading symbol files should be in here now.
3853 (unrecord_misc_function): Remove unused function.
3855 * symtab.h: Remove file-reading things to symfile.h.
3857 * symtab.c: Remove file-reading things to symfile.c.
3859 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
3860 to decode i960 fault types.
3862 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
3863 target.c: Change type of the "resume" function from int to void,
3864 since its result was never used.
3866 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
3868 * main.c: Replace "stupid" with "caution"; you now "set caution
3871 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
3873 * infcmd.c (do_registers_info): Call val_print to deal with the
3874 byte order of the registers being printed. FIXME, this makes
3875 the formatting of the output uglier.
3877 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
3878 defined, call it for signals the debugger doesn't itself use.
3879 The i960 uses this for more detailed fault information.
3881 * remote.c (remote_open): If arg is null, print help rather than
3884 * sparc-xdep.c (register_valid): Avoid declaring size, since
3885 various modules will think of various sizes depending on the
3886 architecture of their tm-file. FIXME, we need protection against
3887 actually entering one of those modules, which would clobber
3888 storage if not for the target architecture compiled into gdb.
3890 * stack.c (up_command, down_command): Always print the frame
3892 (up_silently_command, down_silently_command): New commands
3895 * i960-pinsn.c (reg), i960-tdep.c: Lint.
3897 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
3898 more parameters than it used to.
3900 * findvar.c (registers): Increase slop to 256 bytes, which should
3901 protect us against even most RISC machines with large register
3903 (locate_var_value): Move declaration inside related ifdef.
3905 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
3906 throughout, to avoid throwing away buffered input from the board.
3907 (nindy_wait): Supply_register takes addr_of_value, not value.
3908 (i960_print_fault): Renamed from i80960_fault.
3909 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
3910 (nindy_store_registers): Avoid regs_changed stuff, just stuff
3912 (nindy_create_inferior): Don't bother to write PC_REGNUM since
3913 we can set the PC in the call to proceed(). Unpush nindy_ops
3914 before pushing it on top, to avoid message to user. Eliminate
3915 commentary from Unix machines that just misleads here.
3916 (reset_command): Fix error message to suggest target command.
3918 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
3920 Release 3.92.5 as frozen.
3922 Stabilize the merged release...with help from lint, Saber C,
3925 Everywhere: Add include files needed to declare return types
3926 of functions called.
3928 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
3930 * breakpoint.h: Add undeclared breakpoint functions, and some
3931 functions for display handling since I couldn't think of a better
3934 * breakpoint.c (insert_breakpoints): Make code for disabling
3935 shared library bkpts more likely to work. It's used when we
3936 rerun a program and stop before the shared library has been
3938 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
3939 cast from pointer, so it squeezes through catch_errors.
3940 (bpstat_stop_status): Fix logic broken some time ago. We now
3941 always create a bpstat if the stop address matches a breakpoint,
3942 even if we don't stop there -- just like the old code used to do
3943 before I got my fingers into it (sigh).
3944 (breakpoint_1): Print "ignore count" after "stop only if"
3945 condition, since that's how it actually works.
3946 (mention): Handle watchpoints as well as breakpoints.
3947 (watch_command): use set_raw_breakpoint and mention to do most
3948 of the work (and initialize all the fields!). Only pass one
3949 arg to parse_c_expression, since that's all it takes.
3951 * command.c (not_just_help_class_command): Rename arg to args
3952 since we ignore "unused argument" warnings on vars named "args".
3953 inflow.c (child_terminal_info): ditto.
3954 infptrace.c (kill_inferior): ditto
3955 main.c (catch_errors, version_info, quit_command, pwd_command,
3956 source_command, dump_me_command, editing_info,
3957 set_history_size_command, set_history, show_history,
3959 stack.c (locals_info): ditto
3960 target.c (target_files_info): ditto
3961 valprint.c (set_input_radix, set_output_radix): ditto
3963 * core.c: Remove old variables for handling core and exec file
3964 sections (data_start, data_end, stack_start, stack_end,
3965 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
3966 text_end, exec_data_start, exec_data_end, text_offset,
3967 exec_data_offset, data_offset, stack_offset). They're
3968 superseded the more general build_section_table and
3970 (get_exec_file): Mention the `file' command.
3971 (read_memory_check): Rename to memory_error, and only call it
3972 in the case of an actual error.
3973 (read_memory, write_memory): call memory_error.
3974 (core_fetch_registers): Register section name is ".reg".
3976 coredep.c: Remove a bunch of crud now that all this file does
3977 is pull the registers out of a core file.
3978 (fetch_core_registers): Rewrite to actually work, I hope.
3980 dbxread.c: Use a.out.gnu.h, not system a.out, now.
3981 Replace index() with strchr(). Remove all the pre-BFD macro
3982 definitions for accessing the symbol file.
3983 (struct dbx_symfile_info): Encapsulate the information that
3984 dbx_symfile_init needs to pass to dbx_symfile_read in this
3987 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
3988 dbx_symfile_discard): Rearrange symbol file reading to divide
3989 the format-specific part from the format-independent part,
3990 leaving the format-independent part such as file name expansion
3991 and opening in symtab.c. This replaces
3992 partial_symbol_file_open and partial_symbol_file_read.
3993 Symbol_file_read, add_file, add_file_target_command,
3994 add_file_addr_command move to symtab.c. Pass an explicit
3995 "mainline" flag for when reading the main symbol table, rather
3996 than relying on the offset address to be zero or nonzero.
3998 (dbx_symfile_read): Don't allow void *'s to be printed as
4000 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4001 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4002 macro" debug version really work.
4003 (read_dbx_symtab): Remove unref'd parameter inclink.
4004 Avoid swapping N_SLINE symbols, for speed.
4005 Merge N_TEXT!N_EXT case with the other external symbol
4006 definitions' case. Add comments.
4007 (start_psymtab): Allocate the symfile name in the psymtab on
4008 the psymbol_obstack, rather than using the caller's storage.
4009 (end_psymtab): Only allocate a dependencies list if there are
4011 (psymtab_to_symtab_2): Use BFD when reopening file to read
4012 its symbols for real.
4013 (read_struct_type): Add FIXME comments where it needs work
4015 (read_huge_number): Add FIXME about overflows.
4016 (read_range_type): Add FIXME about comparing a long to 1<<32.
4018 * coffread.c: Minor changes to move things closer to the new
4019 regime with symtab.c and dbxread.c Major work is still needed
4022 * exec.c (exec_file_command): Remove old variables (see core.c
4024 (xfer_memory): If memory transfer is right at the end of a
4025 section, don't lose.
4027 * findvar.c (get_saved_register): If value is in a real
4028 register, LVAL is lval_register, not lval_memory.
4030 frame.h: Declare print_sel_frame and record_selected_frame.
4032 gdb-int.texinfo: New file, for GDB internals documentation.
4033 Very simple, unformatted doc of cleanups is there for now.
4035 gdbcore.h: Remove obsolete variables that described a.out
4036 section addresses and offsets. (See core.c above.)
4037 Declare fetch_core_registers and registers_fetched.
4039 getopt.c: Declare char *alloca(); even on SPARC.
4041 infcmd.c (run_command): Call target_kill rather than
4043 (step_command, next_command, stepi_command, nexti_command):
4044 Declare from_tty parameter even though we don't use it.
4045 (run_stack_dummy): argument BUFFER is a char array, not
4046 a pointer to REGISTER_TYPE.
4047 (finish_command): using_struct_return needed a value *,
4048 not a struct symbol *.
4050 * infptrace.c (child_xfer_memory): To avoid dependency on
4051 where sections are in memory, try PT_WRITE_D and if that fails,
4052 try PT_WRITE_I. Most Unixes don't care which you use.
4054 * infrun.c (step_resume_break_shadow): Change to array to
4055 match other breakpoint shadow storage.
4056 (clear_proceed_status): Pass address of bpstat to
4057 bpstat_clear, not the bpstat itself.
4058 (child_create_inferior): FIXME comment about if the child
4060 (start_inferior): Remove old function.
4061 (child_open): Use target_kill rather than kill_inferior.
4062 (wait_for_inferior): Ditto.
4063 (insert_step_breakpoint, remote_step_breakpoint): Use
4064 new step_resume_break_shadow.
4066 * inftarg.c (child_wait): If all child processes die,
4067 pretend that the one being waited for exited with signal 42.
4069 * main.c (command_line_input): When scanning for comments,
4070 don't coredump on unclosed quotes.
4071 (quit_command): Use target_kill rther than kill_inferior.
4072 (_initialize_main): Rename class_user from "user" to
4075 * printcmd.c (print_command_1): Initialize "fmt" if no format
4076 is specified by the user.
4077 (print_frame_args): Only add to args_printed if we are
4078 actually fetching args from the stack (avoiding undefined
4080 (_initialize_printcmd): Remove bogus \{ from string.
4082 * remote-eb.c (eb_open): Avoid coredump on no argument.
4084 * remote-nindy.c: Bring out of Intel environment into new
4085 target environment. Remove all conditional compilation on
4086 I80960. Massive hacking throughout.
4087 (nindy_xfer_inferior_memory): New routine stolen from
4089 (nindy_create_inferior): New routine pieced together, probably
4090 not quite working yet.
4091 (nindy_ops): New target_ops struct for nindy.
4093 * remote-vx.c: Use write_memory rather than target_write_memory
4094 to get error checking.
4095 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4097 (vx_create_inferior): Use target_terminal_ours...
4099 * signame.c (_initialize_signame): Always initialize, since
4100 we need the table for things other than psignal.
4102 * solib.c (solib_add): Use symbol_file_add, not add_file.
4103 (solib_address): Return boolean result rather than struct
4104 pointer which nobody else knows the type of.
4106 * sparc-tdep.c, valops.c: Use write_memory rather than
4107 target_write_memory, to get error checking.
4109 * stack.c (locals_info, catch_info, args_info,
4110 get_selected_block, frame_command, up_command): Use
4111 target_has_stack, rather than have_inferior_p or
4114 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4116 * symfile.h: New file, defining the interface between the
4117 generic and object-file-specific symbol reading code.
4119 * symtab.c: Move generic symbol-reading interface to symtab.c,
4120 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4121 table to map BFD targets to symbol-reading modules in GDB.
4122 Change index to strchr.
4123 (lookup_struct_elt_type): Use error() rather than hand-made
4124 simulations thereof.
4125 (lookup_partial_symbol): Speedup slightly when length == 0.
4126 (symbol_file_add): New function.
4127 (symbol_file_command): Call it.
4128 (symfile_open, symfile_init): New function.
4129 (add_file_target_command, add_file_addr_command): moved from
4132 * target.c (target_command): use target_kill.
4134 * target.h (target_files_info): Don't declare, never called
4137 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4138 files to determine stack end address.
4140 * valarith.c (value_x_binop, value_x_unop): Change error message
4141 to be more useful. Pass proper argument to value_struct_elt.
4143 * valops.c (value_assign): FIXME comment that long long
4144 bitfields will break here.
4146 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4147 Update `make saber_gdb' to work better.
4149 * TODO: A woman's work is never done.
4151 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4152 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4153 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4154 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4155 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4156 valops.c, valprint.c, exec.c: Lint.
4159 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4161 Continuing Intel 960 port merge of GDB.
4163 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4164 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4165 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4166 Wack over "make depend" so it handles files in subdirectories
4167 vx-share, nindy-share, bfd, and in the current directory.
4169 * blockframe.c (get_prev_frame_info): Remove fatal error
4170 if stack not defined.
4172 * core.c (core_open, core_detach): New functions that handle
4173 the old "core-file" command as "target core" and "detach" instead.
4174 (core_file_command): Call them.
4175 (core_xfer_memory): Use common routine xfer_memory.
4177 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4178 dbxread now uses bfd for everything but symbol reading itself.
4179 BFD internals are used to drag out the relevant file offsets.
4180 (partial_symbol_file_open): Change args all around for BFD.
4182 * symtab.c: Rename "value" to "val" everywhere, so we can
4184 (symbol_file_command): New command, moved from dbxread.c
4185 and coffread.c. It uses BFD to read the file, then vectors
4186 based on its type, to dbx or coff symbol readers.
4187 * symtab.h: Extern a few vars for symbol_file_command.
4189 * target.h: Breakpoint takes a char * save area, not a char **.
4191 * valprint.c (val_print): When unpacking bitfields, offset
4192 the address in gdb of the value, if it is declared with a shorter
4193 type. Remove the last "runtime kludge test" of host byte order.
4195 * utils.c: Remove old my_bfd_read routine.
4197 * stack.c (frame_info): Use target_has_stack. Print program counter
4198 register's actual name rather than "pc", since it's called the
4199 "ip" (instruction pointer) on the i960 (sigh).
4201 * target.c (target_command): Add command for selecting a target
4202 type and calling its open routine. This is used for initiating
4203 communication with a particular target, in a generic way.
4205 * tm-i960.h: Update for modern gdb. Remove semicolons from
4206 various macros. Handle reading struct return convention, and
4207 error-out attempts to return structs with the "return" command.
4208 Be sure gdb doesn't think we know how to call functions in the
4211 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4212 to i960_xxx in lower case.
4213 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4214 not being defined yet.
4216 * remote.c (remote_open): Call start_remote to initialize
4217 wait_for_inferior during open.
4218 (remote_xfer_inferior_memory): Return length written rather
4221 * remote-vx.c (target_command -> vx_open): Use new generic
4223 * remote-eb.c, inftarg.c, exec.c: ditto.
4225 * infrun.c: Fix comments.
4226 (attach_program -> child_open): Use new generic target command.
4227 (wait_for_inferior): Clear saved register values before target_wait,
4228 so target_wait can set some of them if convenient.
4230 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4231 Return success indicator, not void.
4232 (child_xfer_memory): Avoid fetching initial word if we'll
4233 overwrite it anyway.
4235 * infcmd.c (attach_command): Use new generic target open routine.
4236 (_initialize_infcmd): Update doc on attach and detach commands.
4237 (do_registers_info): Merge in a byte-order problem as a FIXME
4240 * findvar.c (find_saved_register): Avoid problem in current frame.
4241 (read_relative_register): Ditto.
4242 (write_register): Convert byte order on the way out.
4244 * exec.c (file_command): Add.
4245 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4246 (xfer_memory): Common function between core_xfer_memory and
4248 (exec_xfer_memory): Use it.
4250 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4252 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4253 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4254 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4256 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4258 Merge Intel 960 port of gdb, continuing...
4260 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4261 symbol_file_command): Pass from_tty arg to hush 'em up.
4263 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4264 Add magic numbers for 960 COFF format.
4266 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4268 Merge Intel 960 port of gdb, from Intel "1.2" release.
4270 CHANGE_LOG entries from their port, which was based on

4274 Remove temp file if download is interrupted.
4276 Wed Aug 1 09:08:33 PDT 1990
4277 Now uses binary protocol to talk to NINDY.
4278 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
4279 Times out after 5 seconds when trying to talk to NINDY.
4281 Tue May 29 12:54:49 PDT 1990
4282 Added variable baud rate (-b switch).
4283 Source code reorganization.
4285 Thu Apr 26 11:09:55 PDT 1990
4286 More cleanup of batch mode; specifically, execute "-s", "-e", and
4287 "-se" switches as soon as they are encountered on the invocation line.
4289 Fri Apr 20 13:47:15 PDT 1990
4292 Thu Apr 19 09:54:28 PDT 1990
4293 Add 'reset' command.
4295 Wed Apr 18 09:48:07 PDT 1990
4296 After opening remote tty, wait for 1 second to go by without input
4297 from it before trying to talk to NINDY (fixes problems with the
4298 Heurikon HK80/V960E).
4300 Mon Apr 4 16:33:05 PDT 1990
4301 Some output was not being suppressed in 'batch' mode.
4303 Thu Mar 22 15:31:11 PST 1990
4304 Ask user if old symbol table should be deleted when new file is
4307 Allow user to run a program downloaded before gdb960 was brought up.
4309 Correct "exec-file" help message for i80960 context.
4311 Correct bug in calculating user space address: could occasionally
4312 corrupt user program.
4314 Make sure to zero low-order bits in rip's because of bug in 960CA
4315 A-step part: could cause operation faults when "next"ing across
4318 Correct bug that made it impossible to get source line numbers for
4319 code loaded at addresses higher than 0x7fffffff.
4321 Wed Jan 10 12:43:22 PST 1990
4322 Open remote tty for exclusive use.
4324 Fri Jan 5 12:14:42 PST 1990
4325 Correct disassembly (CA manual was right after all):
4326 opcode for sysctl is 0x659
4328 Mon Oct 23 12:03:04 PDT 1989
4329 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4331 Mon Oct 16 14:15:09 PDT 1989
4332 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4334 Mon Oct 2 15:56:31 PDT 1989
4336 Added 960CA disassembly support.
4338 To simplify maintenance:
4339 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4341 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4342 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4343 - made disassembly interface identical to that in gdmp960.
4347 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4349 * target.h: Allow targets to stack. Add target_has_memory,
4350 _registers, etc. Restructure memory access and "info files"
4351 to walk the target stack.
4352 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4353 target.c: Change tables to match target.h.

4358 * remote-eb.c: New memory regime, new info files.
4359 * remote-vx.c: New memory regime, new info files. Now use
4360 separate targets for VxWorks attachment to machine, and
4361 actually running a process under VxWorks, since one has
4362 stack & execution & regs and the other doesn't.
4363 * remote.c: New memory regime, new info files.
4364 * sparc-xdep.c (fetch_core-registers): New memory regime.
4365 * target.c: New routines and support for stacked targets,

4406 * TODO, Projects: Lots more stuff to do...
4408 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4410 Massive changes to wall off the remote-debugging interface
4411 behind a function vector. The port to handle VxWorks targets
4412 is also part of this.
4414 All files: Replace references to renamed functions,
4415 remove references to remote_debugging, remove references to
4416 have_include_file, have_core_file in favor of target_has_stack,
4417 target_has_memory, etc.
4419 * Modularize the breakpoint interface.
4420 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4421 a breakpoint instruction.
4422 breakpoint.c: struct breakpoint's shadow_contents now sized as
4424 (insert_breakpoints): Vector to target to install breakpoints.
4425 (remove_breakpoints): Vector to target here too.
4426 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4427 sparc-tdep.c (single_step): Use new breakpoint interface for
4428 the single-step breakpoints.
4429 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4430 New file, contains routines to insert and remove breakpoints by
4431 reading out the old contents and later replacing them. This is
4432 how ptrace breakpoints work, and many remote systems as well.
4434 * tm-vxworks68.h: New config file, overrides a few things for
4435 Wind River's preferences.
4437 * target.h: New file, for transfer vector used to talk to the
4438 inferior (child, attached, core, exec, remote, etc). All accesses
4439 to the thing being debugged should come through these vectors.
4440 target.c: New file, routines to handle transfer vector.
4441 (various files): Add transfer vectors XXX_ops for the various
4442 targets and pseudo-targets (core files, etc) we support.
4444 * breakpoint.c (bpstat_stop_status): Further explorations of
4445 watchpoints and why things don't work all the time.
4446 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4448 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4449 the local gdbinit if it doesn't already have it.
4451 * core.c (core_ops): add and install.
4452 Allow core debugging without exec file.
4454 * dbxread.c (free_and_init_header_files): Merge two fns.
4455 (end_symtab): Free named symbol table when a new version comes in.
4456 (read_dbx_symtab): Relocate all kinds of symbols with base
4457 address. First step toward handling different text, data, bss
4459 (add_file_addr_command): Renamed add_file_command.
4460 (add_file_command): Vector to remote handler.
4461 Add "load" as an alias for "add-file" command.
4463 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4464 non-returning functions.
4466 * exec.c: Add exec_ops, and push it as a target when an exec
4469 * infcmd.c (run_command): Pass executable file name and arg list
4470 separately when starting an inferior. Permit "run" when no exec
4471 file is specified, for VxWorks.
4472 (detach_command): Move to child_detach in inftarg.c.
4474 * inftarg.c: New file. Unix-child-specific routines, and the
4475 child_ops structure.
4477 * inferior.h (registers): Export "registers" as the way for
4478 target dependent register handlers to find gdb's local copy of
4479 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4480 since it is now used by places that want wait_for_inferior to
4481 handle the grunge but want to see every trap from the inferior.
4483 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4484 Eliminate remote_debugging hooks in terminal handling.
4486 * infrun.c: Replace start_inferior with child_create_inferior.
4487 Move all the hair of Unix shells and ptrace idiosyncracies into
4488 child_create_inferior, so remote handlers don't have to deal.
4489 Remove running_in_shell. Rename stop_after_attach to
4490 stop_soon_quietly, and use it in a few other places where we want
4491 to just call wait_for_inferior and get control back on the first
4492 trap. trap_expected now never takes a value > 1.
4493 (init_wait_for_inferior): Initialize static vars when a new
4496 main.c (gdbinit): Add new hook for .gdbinit file name, let
4497 it be overridden by config files as GDBINIT_FILENAME.
4498 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4499 Both of these are used for VxWorks gdb.
4501 mcheck.c: rename include file "gmalloc.c" to avoid problems
4502 with system include file "malloc.c".
4504 param-no-tm.h: New include file, same as param.h but does not
4505 include the default "tm.h" file. This is used in files where
4506 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4508 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4510 remote-vx.c: New file, VxWorks remote debugging support. Uses
4511 RPC routines that are shared with the target system, in directory
4514 remote.c: Vectorize remote interface.
4516 source.c: Globalize source_path, and make an alias "l" for "list"
4517 since we now have the "load" command.
4519 sparc-xdep.c: Use new param-no-tm.h.
4521 symmisc.c (free_named_symtab): Add new function from Wind River.
4522 However, ifdef it out for now while we think about what it should
4525 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4527 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4528 non-Unix-children handle this with their own code in the target
4531 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4532 source and target lists. Add vx-share to default list of include
4533 directories. Add new files to src and target lists: mem-break,
4534 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4535 ${srcdir} versions of munch and createtags are used.
4537 * valops.c (find_function_addr): Split out of call_function.
4538 (call_function_by_hand): Rename call_function; this function
4539 calls functions in the target by laboriously patching the target
4540 word-by-word with the right stack, args, regs, etc.
4543 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
4545 Handle AMD 29000 a bit better.
4547 * remote-eb.c (readchar): Mask received char log to make it readable.
4548 (remote_start): Pass arguments down to executing program.
4549 Make startaddr unsigned.
4550 infrun.c (start_inferior): Accept args, pass them to
4552 infcmd.c (run_command): Pass args down to start_inferior.
4554 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
4555 the target object file format.
4556 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
4558 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
4559 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
4561 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
4563 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
4564 * TODO: We did a few things, we have more to do though.

4567 * inflow.c (inferior_died): Clear deferred stores.
4569 * Debug problems with dummy frames and calls to the inferior.
4570 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
4571 * sparc-tdep.c (do_restore_insn): Simplify.
4572 (sparc_frame_find_saved_regs): Simplify and fix what we find.
4573 (sparc_push_dummy_frame): Simplify and fix what we push.
4574 (sparc_pop_frame): Slightly more hair here, deciding whether
4575 we are restoring a saved PC or returning to a return address in %i7.
4576 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
4578 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
4579 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
4580 * obstack.h (chunkfun): ditto.
4581 * defs.h (xmalloc, xrealloc): ditto
4583 * utils.c (quit): Grab the terminal from the child if necessary.
4585 * inflow.c (term_status_command): Rename to term_info, change
4588 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
4589 (is_delayed_branch): Speed up.
4590 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
4591 Still missing some float ops, and needs testing.
4593 * Support for input and output radixes other than base 10
4594 * defs.h (input_radix, output_radix): Declare.
4595 * expread.y (yyparse, parse_number): Handle changes of input
4596 radix, and ambiguous names-or-numbers in radixes >10.
4597 * printcmd.c (print_scalar_formatted): Print formatted hex
4598 numbers in varying column widths.
4599 * valprint.c (val_print): Use output_format to print scalar ints.
4600 (set_input_radix, set_output_radix, set_radix): Create.
4601 (set_output_radix): Set output_format from output_radix.
4602 (_initialize_valprint): add `set radix' but leave the others off.
4604 * main.c (execute_command): Let stupid questions be turned off.
4605 (_initialize_main): Handle "set stupidity", etc.
4607 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
4608 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
4610 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
4612 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
4613 bfd stuff is still screwed up, but with some manual work, it
4616 * breakpoint.c (bpstat_do_actions): Start over if a command
4617 proceeds the inferior, since the inferior will have stopped and
4618 will need to have its new stop-actions taken care of.
4620 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
4621 compiler fits, simplify it.
4623 * gdb.texinfo (directory command): Doc new dir command.
4624 source.c (directory_command): "dir" now puts things on the front
4625 of the path, moves dups up front, and handles multiple names
4626 on the command line, inserting each one in order. It also
4627 blows away cached line and full_filename info.
4629 * stack.c (backtrace_command): Skip "more stack frames follow"
4632 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
4633 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
4634 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
4635 The only odd one was Gould NP1, which had defined vprintf to
4638 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
4639 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
4640 variable, inspect_it.
4641 valprint.c (print_string, val_print): Use the global inspect_it
4642 to indicate whether to print in Epoch style or normal style.
4644 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
4646 * printcmd.c (call_command): add an alias for the "print" command
4647 which runs expressions and doesn't print the result if void.
4648 (print_command_1): implement it.
4650 * command.c: Remove #if 0'd code. Initialize all the fields
4651 in add_cmd (). Rename do_nothing_command to
4652 not_just_help_class_command, and make it externally visible.
4653 command.h: add user_commands to struct.
4654 * main.c (define_command): Don't overload c->function with a char
4655 string as well as a function pointer.
4657 * eval.c (evaluate_subexp): Reinstall tiemann changes to
4658 calling convention of value_struct_elt () that got dropped in
4661 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
4662 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
4664 * tm-sparc.h (POP_FRAME): replace some constants with defines.
4666 * sparc-xdep.c (store_inferior_registers): defer stores to regs
4667 until a good time (e.g. when we are about to run the child),
4668 saving ptrace calls.
4669 * infrun.c (proceed): handle DO_DEFERRED_STORES.
4670 * tm-sparc.h: define DO_DEFERRED_STORES.
4672 * sparc-xdep.c (store_inferior_registers): when storing float
4673 registers, don't store stack regs too. When storing the SP,
4674 however, DO store the stack regs too. This fixes a bug in which
4675 the dummy frame is not recognized when a call_function finishes,
4676 because its frame pointer (in the stack regs) was never
4678 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
4679 even though we don't know how to read them from an inferior.
4680 valops.c (call_function): Comment about storing SP.
4682 * infrun.c (save_inferior_status): Save away the original bpstat
4683 chain so it can be restored later. Install the copied version for
4684 use by whoever saved the status. It will be blow away by
4685 restore_inferior_status, and the original chain restored. This is
4686 important for people who have pointers into the original.
4688 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
4689 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
4690 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
4693 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
4695 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
4696 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
4697 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
4699 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
4701 * Merge Mike Tiemann's multiple inheritance changes from Sun.
4702 Store the baseclasses in a type struct starting from array element
4703 0 rather than from the unusual array element 1.
4705 dbxread.c: the above.
4706 (virtual_context): Add
4707 Read new debug information about which virtual function table
4708 a virtual function is from, and store it in fn_field.fcontext.
4710 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
4711 TYPE_FN_FIELD_STATIC_P.
4713 symtab.c: the above.
4714 valops.c: the above. Handle pointer casts of object *'s.
4715 (search_struct_method): Add.
4716 (value_struct_elt): First arg is now a pointer to a value, and is
4719 valprint.c: the above.
4720 values.c (value_virtual_fn_field): Add type arg. Handle
4721 offsetting to the proper object when calling virtual fns.
4723 (baseclass_addr): Add valuep arg.
4725 * README: Document the current state of BFD config (missing).
4726 * TODO, ChangeLog, Makefile.dist: Roll version.
4727 * WHATS.NEW: Add summary of changes since 3.5.
4729 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
4731 * dbxread.c (read_struct_type): Clear bit vectors whenever
4733 symtab.c (B_CLRALL): define.
4735 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
4736 using == rather than =. Huh... This fixes the dreaded problem
4737 wherein builtin_type_int becomes TYPE_CODE_FLT.
4739 * core.c (info_files): Show the inferior pid.
4741 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
4742 already knows how to look in the source directory.
4744 * Remove psymtab hair from many places. Remove duplicated code
4745 for searching symbol tables. Hide psymtabs from most places.
4746 Make it fast to get from a psymtab to its symtab.
4748 blockframe.c (blockvector_for_pc): Remove psymtab hair.
4749 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4750 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4751 dbxread.c: export psymtab_to_symtab, make it work if called N times.
4752 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
4753 new symtab completely. New psymtabs get symtab pointer
4754 initialized to zero. Remove MI warning printf.
4755 symtab.h: Comments. Add psymtab to symtab pointer.
4756 (PSYMTAB_TO_SYMTAB): New macro.
4757 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
4758 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
4760 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
4762 (print_frame_info): Avoid special-casing symbols that have not yet
4765 * source.c (open_source_file): Quick path if we have already
4766 located the source file by its full name.
4768 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
4769 find_pc_psymtab. When a name is found in the misc function
4770 vector, search the symbol table for its mangled name, not the
4771 name that the user typed.
4773 * bfd.h: Fix missing comment terminators, make #endifs match.
4775 * valarith.c (value_less): Handle unsigned int comparisons.
4776 Add FIXME about pointer compares, which assume host and target
4777 pointers are the same.
4779 * command.c (do_nothing_command): lint
4780 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
4781 fix comments on debug symbol format for visibility. Actually set
4782 visibility of symbols.
4783 main.c (echo_command): lint; use <readline/history.h>.
4784 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
4785 obstack.h (_obstack_blank): Rearrange pointer math to avoid
4786 pointing past end of allocated memory; saber complains.
4787 obstack.h: Declare the external functions that we use.
4788 valarith.h: use <string.h>
4789 solib.c (solib_add): lint.
4791 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
4793 * main.c (initialize_main): Default info_verbose to off, now that
4794 symbol reading is fast.
4795 (quit_command): Avoid clobbering exec_bfd while quitting.
4797 * Initial BFD (binary file diddling library) merger:
4798 coffread.c: Change AOUTHDR to struct exe_hdr.
4800 core.c: initialize initialized data at compile time.
4801 (core_file_command): Move from coredep.c, convert to bfd.
4802 (xfer_core_file): Convert to bfd.
4803 exec.c (exec_file_command): use bfd routines.
4805 mips-tdep.c: Remove exec_file_command and friends.
4808 * coredep.c: (fetch_core_registers) Convert core_file_command to
4809 fetch_core_registers.
4810 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
4812 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
4813 (my_bfd_read): More bogosity, which I don't think we call.
4814 (program_name): Remove this atrocity asap!
4816 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
4819 values.c: allocate_repeat_value was not clearing the
4820 optimized_out field.
4821 (value_static_field): minor stylistic fix (wrong macro was used).
4822 valops.c (value_struct_elt_for_address): didn't work for C++
4825 * signame.c (_initialize_signame): Initialize signal names once.
4827 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
4828 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
4829 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
4831 * remote-eb.c: Support user-settable baud rates on the serial port.
4833 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
4835 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
4837 * tconfig/sun3os4: Remove warning about native assembler,
4838 since it also occurs in the xconfig file.
4840 * findvar.c (registers): Allocate some slop after `registers'
4841 to prevent stray accesses from trashing the next variable.
4843 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
4844 on the sun-3, by changing the #ifdef from `sun3' (which is not
4845 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
4846 vars, which happened to follow `registers' in the executable.
4848 * readline/history.c (history_search): Heed gcc-2's advice
4849 and parenthesize && inside ||).
4851 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
4852 tm-29k.c: Insert FSF copyright headers.
4854 * remote-eb.c: Better comments.
4856 * Makefile.dist: Update to 3.91.6.
4857 * TODO: note PREPARE_TO_STORE problem.
4859 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
4861 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
4863 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
4865 * infrun.c (wait_for_inferior, at end): Don't set up
4866 prev_* if the inferior no longer exists.
4868 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
4869 CANNOT_EXECUTE_STACK.
4870 valops.c (call_function): Use it.
4872 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
4874 * inferior.h (PC_IN_CALL_DUMMY): New macro.
4875 infrun.c (wait_for_inferior, 2 places): Use it.
4877 * values.c (value_being_returned): Only use
4878 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
4880 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
4881 right thing for remote-eb.c.
4883 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
4884 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
4886 * blockframe.c: Put get_frame_saved_regs inside #if !defined
4887 (FRAME_FIND_SAVED_REGS).
4889 * findvar.c ({fetch,store}_registers): Check for
4890 REMOTE_{FETCH_STORE}_REGISTER macro.
4892 * findvar.c (get_saved_register): Add argument lval and
4893 change meaning of argument addr.
4894 findvar.c: Change calls to get_saved_register to reflect
4895 new calling convention.
4896 valops.c (value_assign): Use get_saved_register instead of
4897 find_saved_register.
4899 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4901 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
4902 an (uninitialized) pointer to one. Use "&" when passing it
4905 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4907 * coffread.c (getfilename): Use DGUX x_offset and x_name if
4910 * coffread.c (symbol_file_command): Put semicolon after
4912 Put safe_to_init_tdesc_context in #if defined (TDESC).
4913 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
4914 coffread.c: #include <sys/stat.h>.
4915 (read_coff_symtab): Typo: in_source_files -> in_source_file.
4916 Add missing ')' in check for "lc%" and friends. Remove
4918 Declare read_one_sym() at top of file.
4919 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
4920 MC68WRMAGIC can have the same value without causing a duplicate
4923 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
4925 * Allow a Makefile to be built without building the
4926 tm and xm file links that screw up builds in subdirectories.
4927 This is done with `config.gdb none', then you can do things
4928 like `make gdb.tar.Z'.
4929 * tconfig/none: Config file for no target system
4930 * xconfig/none: Config file for no host system
4931 * config.gdb: If no TM or XM files are called out by the
4932 host or target file, don't make links for them.
4934 * cplus-dem.c: Add documentation.
4936 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
4937 simple error, so the user's gdb doesn't crash due to some object
4938 file problem (e.g. somebody is rebuilding the file out from under
4941 * printcmd.c (print_address_symbolic): demangle the symbol.
4943 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
4944 Motorola copyrights in it. Make "make gdb.tar.Z" work.
4945 (alldeps.mak): sort and uniq all results from this; duplicates
4946 hose gdb.tar.Z link building. Remove RCS files from
4947 tconfig and xconfig. Add config files for sun386. Add
4948 a few odd files to OTHERS and HFILES.
4950 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
4952 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
4953 Roll version number to 3.91.5. Make lint work in bindir.
4955 * README: Document cross-debugging and new file structure.
4957 * blockframe.c: Lint. Include "value.h" to declare read_register.
4958 (find_pc_partial_function): remove duplicate line.
4960 * command.h: Lint. Declare error_no_arg and dont_repeat.
4962 * tm-news.h: Remove inadvertently duplicated stuff.
4964 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
4965 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
4967 * config.gdb: Allow `config.gdb host target' form. Clean
4968 up previous change that printed bogus messages when you just said
4971 * core.c: #include "command.h" for lint.
4974 * main.c: Remove some casts of enums. Lint.
4981 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
4983 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
4984 read it from memory. This will allow us to save ptrace calls
4985 eventually. Changed caller single_step too.
4987 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
4988 that we aren't going to use, saving many ptrace calls, especially
4989 when watchpointing or single stepping. Use some #define's for
4991 (store_inferior_registers): Ditto.
4992 (core_file_command): Use some #define's for constants.
4994 * tm-sparc.h: Add #define's for some register numbers, so we
4995 can eliminate the use of random constants in sparc-xdep.c.
4997 * stack.c (frame_command, print_frame_info, up_command,
4998 down_command) Remove frame_changed, since it
4999 causes a bug and doesn't seem to do anything useful. In some
5000 places it was used as a flag, in others as a stack level (?).
5002 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5003 default is to use the portable (vprintf) version rather than the
5005 * xm-news.h (MISSING_VPRINTF): Add.
5007 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5009 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5011 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5012 about linking debugged programs -Bstatic in the sun?os4 config
5013 files in tconfig and xconfig subdirectories.
5015 * main.c (main): Remove unreached exit(0) now that we exit
5018 * Create TODO file for online bug list. There are too many
5019 "little" bugs to keep track of on paper.
5021 * Change Projects file to refer to bug-gdb@cygnus.com
5022 rather than kingdon@ai.
5024 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5026 * Makefile.dist (VERSION): 3.91.4 now.
5028 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5029 (condense_misc_bunches): Add sanity check that misc_count is
5030 the same as the number of symbols in the bunch.
5032 * coffread.c: rename init_misc_bunches. Pass an argument
5033 to condense_misc_bunches (a zero).
5035 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5036 every time we are called; don't rely on our caller to do it.
5037 (add_file): Remove call to init_misc_bunches.
5039 * mipsread.c: Only warn, don't error, if unknown symbol types.
5040 This keeps an old gdb from falling on its face if it sees newly
5041 extended symbol info. Rename init_misc_bunches.
5043 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5045 * Merge in changes from Per Bothner for DECstations and other
5046 MIPS stuff. The rest is Bothner speaking:
5048 The next message is a merger of Alessando Forin's mips port with
5049 mine. I've tried to use my good if biased judgment to get
5050 the best of both. It *does* need testing.
5052 Some of the changes are general, *not* mips-specific.
5055 Didn't believe in little-endian bit order.
5056 There are still inconsistencies about whether flags
5057 like BITS_BIG_ENDIAN are integer (#if ...) or
5058 boolean (#ifdef ...). I tried to paper over them.
5060 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5061 Moved some misc_function code that was common to
5062 {dbx,coff,mips}read.c to symtab.c.
5063 In the process, I think I cleaned things up a bit.
5064 At the same time, moved obsavestring and obconcat to symtab.c.
5067 Removed obsolete condense_addl_misc_bunches (use
5068 condense_misc_bunches(1) instead).
5071 Needed to include <sys/dir>, at least on DECstations.
5073 valops.c, mips-tdep.c, tm-mips.h:
5074 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5075 conventions (when STACK_ALIGN is insufficient).
5076 Needed on mips, where doubles need 8-byte alignment,
5077 but ints only need 4.
5080 Removed cruft that was not being used.
5081 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5084 Print $ before register-names (I think that makes things a little
5086 Never print two instructions, even if one delays.
5087 Removed hex-disassemble set_cmd. (This is not mips-specific,
5088 so I think the argument is whether it is generally worthwhile or not.
5089 I'm inclined to think not, given how easy it is to
5090 convert between radixes in gdb.)
5093 This is basically Alessando's code.
5094 It doesn't use obstacks; I changed it to use obstacks
5095 in a few minor places where using malloc causes a
5096 memory leak. (Probably, more places could/should be changed.)
5097 I added record_misc_function where it was missing.
5098 In symbol_file_command and add_file_command, I tried
5099 to make the code consistent with more recent versions.
5100 Minor sylistic changes in parse_procedure.
5101 Make a .gdbinfo. psuedo-symbol point back to the real
5102 procedure symbol (using the isym field).
5105 This is basically from my port, but with a lot of details
5106 and a number of routines merged in from Alessando's version.
5107 I basically used my code "raw" backtrace (use heuristics
5108 from the actual code, rather than symbol table info) - though
5109 the idea is Alessandro's. I feel my code is a little cleaner
5110 here, particularly in being a little more flexible, such as being
5111 able to handle gcc-produced code (which it now can).
5112 It also doesn't do frame caching (which is not useful
5113 more recent gdb versions).
5114 I also used my code for push_/pop_dummy, more or less.
5115 I tried to incorporate AF's code for testing sigtramp
5116 while backtracing; I probably got it wrong.
5117 Added mips_print_register, which tries to scrunch as much
5118 information as possible on a screen...
5119 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5120 under mips-pinsn.c), I don't see anything mips-specific here,
5121 and I don't see it being all that useful anyway.
5124 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5125 Use more register names (rather than hard-cases numbers).
5127 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5129 * Hack up 3.90.11 changes:
5131 * Makefile.dist (depend): parameterize $(GCC).
5132 Add solib.c and solib.o.
5133 (readline): Fix vpath for both absolute or relative SRCDIR.
5135 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5136 Also, let the part I didn't understand at least compile so
5137 I can test the rest. FIXME.
5139 * dbxread.c: Fix thinko using strcmp.
5140 (init_psymbol_list): declare static.
5141 (partial_symbol_file_open): Comment cleanups better, avoid
5142 cleaning up the string table since the caller will do that.
5143 Move the stat for mod time into symbol_file_command, temporarily.
5144 (There should be a mod time for each symbol file, eventually,
5145 to control its rereading. FIXME.)
5147 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5148 SunOS, which gives error for shared libs otherwise. (From
5149 Schaefer, probably FIXME needs work for portability.)
5151 * solib.c: Move #include "param.h" to work.
5152 Lowercase all the Uppercase Letters In the Messages.
5153 (find_solib): Clean up inferior_so_name for debug printouts.
5154 Allow no argument, to mean all shared libraries.
5156 * symmisc.c: include param.h to get CLEAR_SOLIB.
5158 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5160 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5161 to 3.90.11. ChangeLog entries below are from this.
5163 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5167 * Makefile.dist (HFILES): Add tm-sunos.h.
5169 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5173 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5175 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5177 * sparc-opcode.h Added single-operand version of rett.
5179 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5181 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5182 Put parens around gcc_p in expansion.
5184 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5186 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5188 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5190 * Changes for Sun shared libraries:
5191 blockframe.c (find_pc_partial_function): If a non-text symbol
5192 is found, set *address = pc - FUNCTION_START_OFFSET.
5193 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5194 Disable breakpoints instead of giving an error.
5195 source.c (select_source_symtab): Initialize cs_pst.
5196 symmisc.c: Call CLEAR_SOLIB if defined.
5197 symtab.h: Make text{low,high} CORE_ADDR not int.
5198 (psymtab): New field addr.
5200 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5201 (record_misc_function): Give correct type for N_DATA symbols.
5202 (condense_misc_bunches): do "misc_function_count = j" regardless
5204 Take code which is shared between symbol_file_command and
5205 add_file_command and put it into partial_symbol_file_{open,read}.
5206 Split add_file_command into add_file_command and add_file.
5207 Make psymtab_to_symtab read in the string table if the file
5209 Two new parameters to read_dbx_symtab and start_psymtab.
5210 tm-sunos.h: New file.
5212 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5214 * infcmd.c: Change cont_command to continue_command and "cont"
5217 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5219 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5221 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5223 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5224 size 1,2,4,8 rather than size < 8.
5226 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5227 as necessary, not just once.
5229 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5231 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5233 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5235 * tm-news.h: Add CALL_DUMMY_*.
5237 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5239 * config.gdb: In list_host, list_target, use ${i}, not $i.
5241 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5243 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5245 * sparc-opcode.h: Change all store floating-point state register
5246 instructions to have the right match & lose fields.
5248 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5250 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5252 config.gdb: If srcdir != ., create readline directory and
5253 copy a makefile into it.
5255 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5256 consistency with POSIX.
5258 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5259 when we exit its exp_valid_block.
5261 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5263 * Makefile.dist: Bump version to 3.91.3.
5265 * Clean up handling of breakpoint commands (somewhat).
5266 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5268 inferior.h: Add breakpoint_proceeded to inferior status struct
5269 and globals; save it and restore it.
5270 (clear_breakpoint_commands): Cleanup, remove old #define.
5272 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5273 (save_inferior_status, restore_inferior_status): handle it also.
5274 (proceed): Remove earlier code that set breakpoint_proceeded.
5275 It is now set only in clear_proceed_status.
5276 (clear_proceed_status): Cleanup, use bpstat_clear rather
5277 than clear_breakpoint_commands. No callers need the stop_bpstat
5278 between clear_proceed_status and proceed.
5280 infcmd.c: Add breakpoint_proceeded definition and comment.
5281 (cont_command, jump_command, signal_command): Move call to
5282 clear_proceed_status right next to call to proceed.
5284 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5285 caller's argument while running down the chain of breakpoints.
5286 Use new variable "breakpoint_proceeded" to determine when
5287 a command that it executes moves the inferior past the
5289 (bpstat_clear): Handle NULL argument.
5290 (bpstat_clear_actions): Avoid useless call to
5291 breakpoint_auto_delete.
5292 (delete_breakpoint): Clean up bpstat's that are pointing to
5293 the deleted breakpoint from the stop_bpstat chain.
5294 (breakpoint_auto_delete): Simplify.
5296 * Clean up handling of EOF, error on stdin, etc. This was
5297 prompted by a network problem that caused gdb to go into an
5298 infinite loop filling up its malloc'd memory.
5300 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5301 not clear_breakpoints_commands, which is now gone.
5302 (main): If command_loop returns (e.g. from EOF on stdin), do
5303 a quit_command (looping back to command_loop if quit_command
5304 doesn't really quit).
5305 (command_loop): check result from command_line_input and
5306 exit if it returns NULL, rather than passing the NULL to
5308 (gdb_readline): Free malloc'd result space before returning
5311 * utils.c (query): Handle C-d to mean "yes", just as if the
5312 input was not a terminal. Also avoid infinite loop if EOF
5313 occurs in mid-input-line before newline. This allows
5314 query to be used at EOF on stdin with reasonable results.
5316 * infrun.c (proceed): Set breakpoint_proceeded.
5318 * values.c (value_as_long): Avoid infinite recursion for enums.
5319 (_initialize_values): Fix typo in help msg (kingdon).
5321 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5322 RL_LIB for linking. This allows -lreadline for linking
5323 and nothing for dependencies, once readline is a real library.
5325 * config.gdb: Jim Kingdon: give useful error message if the
5326 host or target type is not recognized.
5328 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5329 it just defines it. Dumb, but deal with it.
5331 * Jim Kingdon suggests:
5332 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5334 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5336 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5338 * Clean up Bothner's changes.
5340 * blockframe.c (clear_pc_function_cache): New function.
5341 * blockframe.c: remake cache_pc_function_* static.
5342 * dbxread.c (symbol_file_command): remove references to
5343 cache_pc_function_* variables.
5344 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5345 * printcmd.c: Avoid kludging a global variable (addressprint)
5346 to avoid printing the address of a string twice. Instead,
5347 pass the format letter 's' down low enough that it can be seen
5348 to avoid this problem.
5349 (print_formatted): Pass format arg to value_print.
5350 (restore_addressprint): Remove function.
5351 (do_examine): Avoid hacking addressprint, cleanups and such.
5352 (print_frame_args): Add a comment to a Bothner change.
5353 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5354 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5355 to wipe out the values cached in blockframe.c.
5356 * symtab.c (find_method): Add comment saying how big you must
5357 allocate to be "big enough". Per being terse again.
5358 * valprint.c (val_print): Handle format letter "s" to print
5359 strings without addresses. Add comment to vtbl printing code
5360 which casts with wild abandon. Rearrange reference-printing
5362 @0xaddr: value (print w/addressprint)
5363 value (print w/~addressprint)
5364 @0xaddr (parameter lists w/addressprint)
5365 or nothing (parameter lists w/o addressprint)
5367 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5369 * Merge more changes from Per Bothner:
5371 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5372 annoying) that I tried to improve it. Here are my suggestions.
5374 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5377 Do automatic de-reference when taking the address of a reference.
5379 Don't deref_ref when printing parameter lists.
5381 More attempts at treating refernences properly.
5383 In val_print, if deref_ref==0, don't print dangling " = ".
5385 Add COERCE_REF macro, which de-references an REF.
5387 * Merge changes from Per Bothner:
5389 * Fixed (Sony news)-specific configuration problems.
5390 * Fixed other problems with using vanilla pcc and libc (enum problems;
5391 assumption that vsprintf exists).
5392 * Some major speed-ups (finc_pc_partial_function now caches a match;
5393 parsing avoids duplicate symbol_lookup calls).
5394 * Changed handling of baseclasses (no longer use baseclasses field
5395 of struct type, use the first n_baseclasses fields instead).
5396 * Various minor changes/fixes, most C++-related.
5399 Cache the most previous match from find_pc_partial_function.
5400 (Save both low and high ends of matching function's pc range.)
5401 This speeds up the loop of infrun.c:wait_for_inferior quite
5402 a bit, and makes step/next commands much zippier.
5404 Added an enum->int cast (otherwise, some compilers barf).
5406 No longer set baseclass offset to 0, since multiple
5407 inheritance now mostly works.
5408 Added a number of casts, to shut up compiler warnings
5409 (after stabs where made enums, not ints).
5410 When discarding a symbol table (in symbol_file_command),
5411 must clear the cache introduced in blockframe.c.
5412 Don't convert $vtbl_ptr_type to vtbl any more.
5413 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5414 Mask off sign bit emitted by g++ for virtual table offset.
5415 Set voffset to -1 (not 1) for static member functions.
5417 Changed parsing/lexing of names to avoid doing symbol lookup twice
5418 (once when lexing to determine symbol class, once for real).
5419 Now only call symbol_lookup once. Fields of 'this' win especially big.
5421 Subpress printing addr twice in the case of 'x/s addr'.
5423 lookup_basetype_type is no longer used.
5424 Add find_methods as recursive helper function to decode_line_1.
5425 This allows multiple inheritance to work.
5426 Also, once one or more matches has been found, do not look in
5427 base-classes. (Baseclass methods would be overridden, anyway.)
5429 Removed baseclasses array in struct type.
5430 Instead of using baseclasses[i], use fields[i-1].
5431 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5432 Changed sign convention of voffset (previous was inconsistent).
5434 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5436 Used to assume existence of vsprintf. Re-written to not need it
5437 if HAVE_VPRINTF is undefined.
5439 typecmp was too pessimistic. Made it less so.
5441 Don't print space after address.
5442 If vtable points to a misc symbol (with 0 offset), print it,
5443 since that indicates the actual class of the object.
5444 Changed ype_print_derivation_info to use new inheritance
5445 scheme (without baseclasses vector).
5447 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5448 Also, changes needed because TYPE_BASECLASSES were removed.
5450 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5452 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5455 If there is no path set, and the symbols don't indicate what directory
5456 a file was compiled in, look in the current directory. But either
5457 a path or a known compilation directory will prevent this.
5460 Three independent bug fixes:
5461 * Remove the #if 0 block that breaks some stuff.
5462 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5463 adapt gdb to either SunOS 4.0.* or 4.1.
5464 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.

5479 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5481 * Changes merged by John Gilmore:
5484 In breakpoint_1, use new print_address_symbolic instead
5485 of find_pc_partial_function. (This forces use of assembler-level
5486 addresses, and avoids misleading non-mangled source-level names.)
5488 Generalize ansi argument such that -1 means skip arglist totally.
5489 Removed global variable print_ansi_qualifiers (which made
5490 code non-reentrant), in favor of extra explicit arguments
5491 to internal routines.
5493 Add new helper function print_address_symbolic.
5494 Use find_pc_misc_function instead of find_pc_partial_function
5495 (since we want assembler-level symbols here).
5497 Print unknown function as just "f (...)", not "f (...) (...)".
5498 Use new fputs_demangled explicitly.
5500 Fixed a typing violation (problem: value.h cannot be imported
5501 without renaming many variable in this file).
5502 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5503 decode_line_1: Moved forward some never-reached code.
5504 Made decode_line_2 skip function prologues correctly.
5506 fputs_filtered should not demangle by default.
5507 Add new fputs_demangled to demangle on demand..
5509 Change value_struct_elt to use value_primitive_field (using recursive
5510 utility function search_struct_field). This allows foo.bar to work
5511 for multiple inheritance (so far only for data fields).
5512 Change check_field in the same way (recursive helper function
5513 to support multiple inheritance).
5514 (Note: there are more of these problems that I haven't fixed.
5515 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5516 value_of_this: 'this' symbol name is now just "this", note "$this".
5518 Don't print static members.
5519 Avoid printing "members of <type>" if there are none.
5520 Simplified type_print_derivation_info by merging duplicate code.
5521 Remove useless blank lines in type_print_base (ptype command).
5523 Added declaration of new routine value_primitive_field.
5525 Added value_primitive_field which is generalized version of
5526 value_field that can handle multiple inheritance (non-zero offsets etc).
5527 Re-implemented value_field to call value_primitive_field.
5529 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
5531 * infcmd.c -- insert else to avoid 'delete env' coredump when you
5532 delete the whole environment. Karl Berry reported the bug.
5533 * source.c - fix openp to avoid //'s in filenames, which
5534 trigger an Emacs bug causing it to not be able to find files
5535 when running gdb in a window.
5536 * dbxread.c - zap the #if 0 that botches the add-file code.
5537 It seems to work a lot better without all the code commented out.

5541 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
5544 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
5546 * Makefile - added a ${CFLAGS} to a couple of entries,
5547 added remote-sa.sparc.c
5548 * added remote.sa-sparc.c, a modification of remote.c
5549 which conducts a dialog directly with the SparcStation prom.
5550 * breakpoint.c, infrun.c, sparcdep.c added
5551 remote_insert_breakpoint(), and remote_remove_breakpoint()
5552 to breakpoint.c instead of directly writing breakpoint instructions.
5553 * sparcdep.c on remote_debugging,there is no need
5554 to remove signle step breakpoint instructions.
5555 * main.c added "-epoch" flag and "int epoch_interface" to main.c
5557 * printcmd.c - epoch interface sends lisp expressions to open up
5558 epoch windows on inspection.
5559 * valprint.c - added arrayprint, and addressprint and made adding
5560 format controls easier
5561 * wait.h added a couple of undef's because we were getting
5562 complaints about WSTOPSIG and WTERMSIG begin redefined.
