1 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
3 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move
4 REGISTER_U_ADDR to corresponding xm- file. Sugg. by Peter Schauer.
6 * symmisc.c (print_partial_symtabs): Add printpsyms debug cmd.
8 * m68k-tdep.c (m68k_push_dummy_frame, m68k_pop_frame): Add
9 generic routines for calling inferior functions.
11 * blockframe.c (inside_main_scope, inside_entry_scope): New.
13 * copying.awk: Filter formfeeds out of copying & warrantee.
14 Make them available as `show copying' and `show warrantee' also.
15 * main.c (print_gnu_advertisement): Advt `show' commands.
17 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)
19 * mach386-xdep.c: Even when cross-compiling, leave in the
20 core-file reading code.
21 * core.c (get_core_registers): Avoid coredump if no .reg section.
23 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
25 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
26 This avoids coredumps under `set print object on' in value_headof
27 (called erroneously by value_from_vtable_info) for `p &struct'
28 or `p *struct'. From Peter Schauer.
30 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
32 * Makefile.in: Roll version to 4.1.2.
33 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
34 size from BFD (but, FIXME, we don't yet read external nlists's and
35 convert them to internal nlists's before handling them -- we still
36 assume they have the same size and alignment.) Use SET_NAMESTRING
38 * exec.c (exec_file_command): Move dead coff-encapsulation code
40 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.
42 Fri Oct 4 22:30:06 1991 John Gilmore (gnu at cygnus.com)
44 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
45 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
47 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
49 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
50 * mips-xdep.c (store_inferior_registers): Don't try to
51 write the (pseudo) FP.
52 * mipsread.c (parse_partial_symbols): Improved algorithm for
53 setting pst->texthigh.
55 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
57 * doc/Makefile: make TEXINPUTS include . everywhere
59 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
61 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
62 vestiges of typevectors, which were for symsegs and are no longer
63 used. (From a question by Eliot Dresselhaus
64 <dresselh@RFT30.nas.nasa.gov>).
66 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
68 * dbxread.c, coffread.c: static-ize functions that were
69 gratuitiously external. (From Fred Fish.)
71 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
73 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
74 until it is large enough.
76 * dbxread.c (read_type): Handle error case slightly better.
77 Make complaint message not C++-specific.
79 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
81 * infrun.c (wait_for_inferior): Fix step/next so that you only
82 stop at the beginning of a new line. This fixes various problems
83 with for loops, nested if-else's and switch statements.
85 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
87 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
88 between symtabs and psymtabs become ordinary error()s.
90 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
91 properly, making "end pc" correct in shared lib psymtabs.
92 (From Guy Harris <guy@auspex.com>.)
94 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
96 * dbxread.c: Enable, but soften, const_vol_complaint.
97 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
98 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
99 should be file-scope, not global.
100 (read_struct_type): Remove ancient multiple-inheritance warning.
101 (read_range_type): Check base type, complain & patch if undefined.
102 * stack.c (frame_info): Demangle the function name in `info stack'.
105 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
107 * eval.c (evaluate_subexp_for_address): Don't use
108 TYPE_POINTER_TYPE directly (it might be zero if this type has
109 never had a pointer created before); use lookup_pointer_type.
110 * symtab.c (lookup_method_type): Arguments were swapped in all
111 callers, so fix it here. I'm amazed this worked at all!
113 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
115 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
116 "bss" rather than "data" symbols, but which still conflict.
119 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
120 * core.c (core_files_info): Shorten output.
121 * exec.c (exec_files_info): Ditto.
122 (build_section_table): Ignore zero-length sections.
123 * language.c, printcmd.c: Lint.
124 * language.h (get_frame_language): Declare.
125 * saber.suppress: update.
126 * stack.c (find_relative_frame): Remove complex code that was
127 #if 0'd, stick with simple code. Lint.

129 * symfile.c (add_symbol_file_command): Add "?" to question.
130 * utils.c (parse_escape): Avoid \a due to bdead compilers.
131 * value.h: Declare typedef_print.
133 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
136 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
137 (Reported by Mark Peek <mark@imagen.com>.)
139 * solib.c (solib_map_sections): Relocate all sections, even
140 though only the text section's size is tracked. Mark ld_text
141 for eventual elimination as we generalize to N sections.
143 * infrun.c (wait_for_inferior): Don't check if the PC is in a
144 call_dummy if we were stopped by a random signal that is being
145 passed to the program. This produced wierd results when calling
146 functions in the inferior and signals (e.g. SIGALRM) were in use.
148 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
150 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
151 Bugfix from Paul Eggert <eggert@twinsun.com>.
152 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
153 * valprint.c (print_floating): Print 9 digits for IEEE floats.

162 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
166 * Makefile.in (VERSION): Set to 4.1.
167 * language.c (set_language_command): Print useful help message,
168 and restore the language string after giving help.
169 * valprint.c (typedef_print): Print typedef in C or M2.
170 * symtab.c (list_symbols): Use it.
171 * main.c (main): Avoid any output before (gdb) prompt when -q.
172 * language.c (set_language_command): Handle errors by restoring
173 the language string to its current state (fix from A. Beers).
174 * doc/gdbint.texinfo: Roll in information from README. Rearrange
175 "how to install" and "how to print the doc" stuff so it drops
177 * configure.in: Rename rtpc CPU to romp to match config.sub.
178 * README, WHATS.NEW, TODO: Update for gdb-4.1.
180 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
182 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
183 autoloading shared libs, copyright etc on GDB startup, clean up $_
184 and $__ index refs, set/show listsize and related updates to list
185 cmd. New host/target configs.
187 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
189 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
190 from main Makefile.in version definition
191 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
193 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
195 * doc/gdb.texinfo: merge new language-switching and lang-specific
198 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
200 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
201 compilers (which may lack stddef.h).
203 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
205 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
206 N_WARNING are the same except for the N_EXT bit, so just use their
207 values alone, rather than OR-ing them with N_EXT.
209 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
211 * mipsread.c (parse_lines): Deal with negative extended line
214 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
215 global symbol conflicts.
217 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
219 * .gdbinit: Move 'set complaints' to top, so it runs even in
220 case we aren't debugging GDB.
221 * language.c (_initialize_language): Fix type check and range
222 check documentation strings.
223 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
224 language.c can use it. (Though language.c should really not be
225 handling warnings/errors the way it does, FIXME.)
226 * symtab.c (lookup_primitive_type): const lint.
228 Bugfix from Peter Schauer:
229 * source.c (lines_to_list): Make signed, to avoid comparison
230 going unsigned and complaining that -3 is too high for 21 lines.
231 * stack.c (lines_to_list): Ditto.
233 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
235 * Makefile.in (HFILES): Add minimon.h.
236 (VERSION): Roll version number to 4.0.95.
237 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
238 New rules for building distributions. Normal distribution
239 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
240 one level up from here; it calls make-proto-gdb.dir to build a
241 directory `proto-gdb' which is an image of the release. The old
242 `gdb.tar.Z' rule still works too.
243 * config.sub, configure: Roll in latest from ..
245 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
247 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
248 new-target, and new-config chapters; fix minor typos; come closer
249 to usual GNU markup conventions for @file @samp @code @var.
251 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
253 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
254 * mipsread.c (parse_partial_symbols): Enter the name of all
255 structs/unions... into the psymtab so we can access them if the
256 symtab is not read in.
257 * mips-tdep.c: Remove some unneeded #includes.
258 * xconfig/dec3100: Add HAVE_STRSTR.
260 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
262 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
263 * c-exp.y, m2-exp.y: Lint.
264 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
265 * valprint.c (val_print_fields): Check for stub type.
266 * mipsread.c (_initialize_mipsread): Avoid using
267 builtin_type_void at initialize time.
268 (mipscoff_symfile_read): use it now.
270 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
272 Merge multiple-language support, and partial Modula-2 support,
273 from Andrew Beers <beers@cs.buffalo.edu>.
275 * i387-tdep.c: New file, consolidates most 80387 support,
276 and eliminates host dependency on double<->extended conversions.
277 * i386-xdep.c, symm-xdep.c: Remove most 387 support.
278 * xconfig/i386{sco,v,v-g,v32,v32-g}: Now need i387-tdep.o.

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

369 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
371 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
372 entries are enclosed herein. Not all of these changes
373 have been merged into the master GDB sources -- check the
374 ChangeLog above here for the merge log.
376 Mon Jun 3 17:05:45 EDT 1991
378 m2-exp.y Created. Tested outside of GDB for a few days. Proper
379 operators were added, C specific operators and tokens
380 removed. yylex() revamped to some extent. Still things
381 missing from the grammar, such as sets.
382 Tested for two weeks in GDB v3.5.
384 Tue Jun 11 17:23:48 EDT 1991
386 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
387 so they are built-in. Sort of a hack.
389 Fri Jun 14 12:53:51 EDT 1991
391 m2-exp.y Added range checking for numeric constants. Any numeric
392 constant is assumed to be of builtin type INTEGER unless:
393 (1) it is octal or hexadecimal, in which case it is a
394 CARDINAL; (2) it is too big to fit into an INTEGER, in
395 which case it is a CARDINAL.
396 eval.c Added simple range checking for +, -, and * on integers.
397 Doesn't work very well for *, since 6 * 1,000,000,000 =
398 1,705,032,704, which fails the simple test of result >=
399 first_operand, no matter in what order the operands are.
401 Tue Jun 18 14:11:30 EDT 1991
403 Broke the parser into parts, one containing the C grammar and the other
404 containing code to be shared by all of the grammars.
406 The following files no longer exist:
411 The following files were added:
413 c-exp.y (The C grammar)
414 m2-exp.y (The Modula-2 grammar)
415 parser-code.c (Code that is shared by the above grammar)
419 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
420 now necessary to use the Bison compiler compiler, since it
421 will generate function/variable prefixes other than yy.
423 Tue Jun 18 16:47:49 EDT 1991
425 symtab.[ch] Added the external variable working_lang, than holds the
426 value of the current working language.
427 Added the ennumerated type language_mode, with the values
428 language_auto and language_manual, the former meaning that
429 GDB sets working_lang as needed, and the latter meaning
430 that the value of working_lang is totally under user
432 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
433 REAL, BOOLEAN and CHAR. Also added the type codes
434 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
435 utils.c Added set_language_command and show_language_command to
436 implement the GDB support commands "set language" and
438 expression.h A number of identifiers were added to the type exp_opcode
439 to facilitate Modula-2 builtin functions, integer
440 division, and array indexing.
442 Wed Jun 19 13:25:58 EDT 1991
444 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
445 if the language specified by working_lang requires the use
446 of strict typing of expressions. Eventually, even this
447 will be able to be changed by the user.
448 Added the macro RANGE_CHECK, which evaluates to non-zero
449 if the language specified by working_lang requires the
450 checking of a value against the domain of its type.
451 Eventually, even this will be able to be changed by the
453 language.[ch] Predicates involving types (simple_type, ordered_type,
454 same_type, integral_type, numeric_type, character_type,
455 boolean_type, float_type) are added. These predicates are
456 based on the current value of working_lang, and are handy
459 Wed Jun 19 15:39:34 EDT 1991
461 eval.c Added the function type_array_rank which computes the rank
463 valarith.c Added the funtion value_bool, which when given a integer
464 value.h value (ie. struct value *) as an argument, it returns a
465 boolean value (ie. struct value *) true if that integer
466 is non-zero, and a boolean value false otherwise.
467 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
468 will print out properly.
470 Wed Jun 19 16:36:34 EDT 1991
472 valops.c Added the function value_capitalize, which returns it
473 value.h argument capitalized if its argument is a lowercase
474 letter, or the argument unchanged if its argument is not a
476 valarith.c Added the function range_check_p, which returns non-zero
477 value.h if its value argument is between the integral bounds upper
479 Added the function range_check_enum_p, which makes sure
480 that its value argument is a valid member of the domain of
482 Added the function range_check_range_p, which makes sure
483 its value argument lies between the upper and lower bounds
484 of its type argument, which must be a ranged type.
485 Added the function check_array_index, which range and type
486 checks an index of an array.
487 Added the function value_multi_subscript, which computes
488 array[idx1,idx2...idxN], given a value array and an array
489 of values representing indicies.
490 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
491 unpack_long to work with TYPE_CODE_BOOL and
494 Wed Jun 19 18:04:08 EDT 1991
496 symtab.c Stored pervasive types in a structure and make
497 lookup_pervasive_type() a lookup function that was based
498 on working_lang. If lookup_pervasive_type() returned
499 non-zero, then that value was returned (a fix, since
500 before it simply wouldn't return the pervasive type.)
501 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
502 non-zero if the language specified by working_lang means
503 "conversion" when it says "cast".
504 valops.c Added the function value_real_cast(), which performs a
505 value.h *cast*, not a *conversion*, which is what value_cast()
506 does when it can. In particular,
507 value_cast(<float_type>,4) = 4.0, while
508 value_real_cast(<float_type>,4) = some mess.
509 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
510 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
511 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
512 and MIN on integral types. *NOTE*: These are currently
513 hardcoded to work only if there are 8 bits per storage
515 eval.c Made logical functions call value_bool to return a
516 properly typed boolean value, based on working_lang.
518 Thu Jun 20 11:55:27 EDT 1991
520 valprint.c Types now print out in a Modula-2 fashion. This works for
521 the cases when the type is printed out step-by-step, that
522 is, it doesn't work when the name of a structured type
523 (which includes the keyword "struct", etc.) is simply
525 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
526 since type specifications in C and Modula-2 are very
527 different. The C printing of a type is very recursive,
528 whereas in Modula-2 it is generally very simple. C has
529 type prefixes and suffixes, which have no real analogue in
530 Modula-2. Maybe type_print() should call a language
531 specific type printer. This is also advantageous if we
532 compile GDB to exclude some of the languages. We'll just
533 leave those functions out.
535 Thu Jun 20 16:57:10 EDT 1991
537 dbxread.c When reading the complete symbol table in (via
538 psymtab_to_symtab()), the number and types of function
539 arguments are added to a function type. define_symbol()
540 calls add_param_to_type() to accomplish this.
541 Assumption: when we come across a function definition
542 (N_FUN symbol with an 'f' or 'F' in the name), its
543 arguments will appear before another function definition.
544 When a function is found, a pointer to its type is placed
545 in the global in_function_type. Changes that
546 add_param_to_type() makes are to this global.
547 valprint.c The type of a function now includes (for Modula-2) the
548 types of its parameters.
549 eval.c Type checking and a check for the proper number of
550 arguments is now done for function calls. Not sure of the
551 impact this has on C++ member function yet.
553 Thu Jun 20 19:58:48 EDT 1991
555 valprint.c Rewrote the type printer. Broke it into two language
556 specific parts, adding the functions type_print_m2() and
558 An unfortunate consequence is this: if you debugging a C
559 program in Modula-2 mode (why?), info types does not work
560 well with regular expressions, since the types are printed
561 out in Modula-2 terminology, but stored in C terminology.
562 language.[ch] Added the functions new_type_last(), type_keyword(), and
563 type_sep() to aid in the printing of typedefs.
564 symtab.c Made the printing of typedefs as language independent as
565 possible through calls to new_type_last(), type_keyword(),
568 Fri Jun 21 11:50:26 EDT 1991
570 dbxread.c Check all incoming ennumerated types. If it looks like
571 Modula-2's BOOLEAN type, then change the type_code of the
572 type to TYPE_CODE_BOOL so we can process it as a boolean
574 valprint.c Replaced some of the 0x%x with calls to sprintf and
575 hexformat() in val_print().
576 language.[ch] Added the function hex_to_string(), which converts its
577 integral argument to a hexadecimal number (format is
578 language based) and returns the result as a string.
580 Mon Jun 24 12:25:07 EDT 1991
582 valprint.c Some functions call type_print_1() directly, instead of
583 value.h using type_print(), so they can specify where (column) to
584 print things. Since type_print() takes care of language
585 dependence, that needs to be called first. Added a
586 parameter depth to type_print() (so it is now like
587 type_print_1). Changed type_print to type_print_at, and
588 made type_print a macro that passes a depth argument of
590 symmisc.c Changed all calls to type_print_1 to calls to
592 Makefile.dist Made it possible to build GDB for a specific set of
593 depend languages. Do this by passing a definition for the macro
594 LANGS to make. LANGS should be a string containing a
595 space-separated list of language names (ie. LANGS="c m2").
596 The default is to build all languages. Note that grammar
597 files must follow the naming convention of <lang>-exp.y.
598 gdb.lang This holds the current value of the LANGS macro. It is
599 examined every time make is called, and is updated if
601 eval.c Added #ifdef _LANG_<lang> to these files.
602 expread.c Still need to add them to dbxread.c and coffread.c.
610 Mon Jun 24 16:33:11 EDT 1991
612 language.[ch] Added the functions hexformat_pre() and
613 hex_to_string_pre(), which take a prefix argument to
614 include in the format string. Thus, hexformat_pre("08") will
615 return "0x08x" (if the working language is language_c).
616 Made hexformat() and hex_to_string() calls to the above
617 with "" as the prefix argument.
619 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
620 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
621 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
622 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
623 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
624 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
625 valprint.c, vax-pinsn.c
627 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
628 calls to hexformat() and hex_to_string(). Format strings without
629 the leading "0x" were ignored.
631 depend Updated to take the above into account.
634 Tue Jun 25 15:27:18 EDT 1991
636 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
637 and type_check_t to keep track of the current state of
638 range and type checking.
639 main.c Added the variables range_mode, range_check, type_mode,
640 and type_check to record the current state of range and
641 type checking. Added initialization code to main().
642 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
646 Tue Jun 25 17:57:08 EDT 1991
648 dbxread.c process_one_symbol() updates the variable (enum language)
649 source_lang based on the extension of the filename
650 contained in the N_SO sybmol that started this symtab.
651 When end_symtab() is called, the value of source_lang is
652 put into the language field.
653 stack.c select_frame() sets working_lang (and possibly type_check
654 and range_check) to the language field of the symtab
655 associated with the frame that is selected if working_mode
656 is language_auto. If working_mode is language_manual, a
657 warning is printed and working_lang is not set.
658 language.c Added the function set_type_range(), which sets the value of
659 type_check and range_check (if their modes call for
660 automatic setting) based on the current value of
661 working_lang. A non-zero argument will cause the current
662 settings to be output.
665 Wed Jun 26 14:51:40 EDT 1991
667 eval.c Added range checks on assignment.
668 m2-exp.y Added the grammar for sets to the language. Currently,
669 these do not do anything except print an error message.
671 Wed Jun 26 17:01:04 EDT 1991
673 m2-exp.y Added the ability for parse_number() to parse negative
674 numbers. A global flag is set upon encountering a unary
675 minus. This was done to make, for example, 1 parse as a
676 CARDINAL, and not as an integer, per Wirth's examples in
677 Programming in Modula-2 ed.4.
678 valprint.c Added support for "set radix 2" by then setting
679 output_format to 't'.
680 eval.c Implemented range checking on subrange types. Added calls
681 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
682 Implemented MIN and MAX for ennumerated types. The
683 minimum value of an ennumerated type is defined by Wirth
684 as the first identifier, and the maximum as the last.
685 m2-exp.y Made octal numbers ending with "B" be characters and those
686 ending with "C" be numbers, per Wirth's book. (p. 34)
688 Thu Jun 27 14:11:52 EDT 1991
690 stack.c select_frame() now only sets working_lang, it does not
691 notify the user. If working_mode is language_manual, then
692 a warning is issued once.
693 main.c At the end of each call to execute_command(), working_lang
694 is checked against the local static (enum language)
695 current. If they differ and working_mode is
696 language_auto, the new settings of language, type and
697 range checking are printed out.
698 stack.c Modified frame_info() to include the language of the
699 current frame in the output of "info frame".
700 language.[ch] Added the function language_str() which returns the name
701 of the current language.
703 Fri Jun 28 15:33:14 EDT 1991
705 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
706 the language. INCL and DECL currently cause an error,
707 since sets are not implemented yet. INC and DEC are
708 implemented as PREINCREMENT/PREDECREMENT with one
709 argument, and as ASSIGN_MODIFY with two arguments.
710 eval.c Added type checking to the above cases.
711 value.h Added not_lval_constant to the lval_type ennumerated type.
712 not_lval_constant means that the value is a constant
713 value; that is 3 or 'a' or TRUE, not as in a constant
714 identifier. This is used to help coerce numbers such as 3
715 to either signed or unsigned numbers.
716 valops.c Added the function value_coerce_constants() which coerces
717 constant integers as following: if one is a constant and
718 the other is not, the constant's type is set to the type
719 of the other argument. If both are constants and one is
720 signed, the other is converted to a signed constant.
722 Sat Jun 29 17:26:29 EDT 1991
724 valarith.c Added a better range checker. It now checks range
725 (successfully) on integral operations [+-] (signed and
726 unsigned) for any C sized type. Still does not work well
728 int_in_size() returns an integer that is coerced to fit into
729 specified number of bytes.
731 Mon Jul 1 13:04:14 EDT 1991
733 language.[ch] Added the function binop_result_type(), which returns the
734 builtin (struct type *) type that would be the result of a
735 binop on the two values V1 and V2.
737 Wed Jul 3 19:22:53 EDT 1991
739 source.c Extended source_info() to include the source language in
740 the output from "info source".
742 Fri Jul 5 13:48:52 EDT 1991
744 utils.c Moved the support functions for the GDB set/show commands
745 dealing with language into language.c.
746 language.c Added the function language_info(), which displays info
747 about the current working language, type and range check
748 settings. Called via the GDB command "info language".
749 Added an initialization routine _initialize_language(),
750 that sets defaults for the language, type and range
751 variables and sets up the new GDB commands.
752 main.c Language setup moved to language.c.
755 Mon Jul 8 10:10:22 EDT 1991
757 valarith.c Debugged the range checker for arithmetic. Still does not
758 work for multiplication very well.
760 Mon Jul 8 12:40:37 EDT 1991
762 language.[ch] Added the function value_true() which returns non-zero if
763 its argument represents a boolean true value.
764 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
765 check the truth of an expression.
767 Thu Jul 11 12:51:34 EDT 1991
769 language.[ch] Added the predicate structured_type(), which returns
770 non-zero if the argument is a structured type.
771 Added the predicate pointer_type(), which returns non-zero
772 if the argument is a pointer type.
773 eval.c Added the ability to do addition and substraction on
774 pointers and integers. This case simply bypasses the
777 Thu Jul 11 14:41:42 EDT 1991
780 Added the symbol N_DEFD (0x4a) which is a definition
781 module dependency that is used by the GNU Modula-2
782 compiler and the linker. It is not important to GDB,
783 except that [dbx|coff|mips]read.c should ignore these
786 Fri Jul 12 16:07:00 EDT 1991
788 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
789 0 in val_print(). Also added statements to the else part
790 to coerce type (argument to val_print) to a pointer type
791 if it is an "array of unspecified length".
792 valops.c Added the function value_m2_string(), which returns a
793 (value) value which is a constant string, whose type is
794 (ARRAY [0..n] OF CHAR). The length field of the type
795 structure is set to zero, so it will be interpreted as an
796 "array of unspecified length".
797 stack.c Moved the language/frame mismatch check to
798 main.c:execute_command().
799 main.c The working language is recorded each time
800 execute_command() is executed. If working lang has
801 changed during its execution, then the new
802 language/type/range info is printed out for the user. If
803 the working language does not match the language of the
804 frame, a warning is issued.
806 Sat Jul 13 16:16:39 EDT 1991
808 eval.c Moved all the type-checking stuff for operators to
809 language.[ch] language.c. This is so we can keep language-specific
810 stuff (like for what type operators are defined) in
812 language.[ch] Added the function binop_type_check(), which checks to see
813 if its two (value) arguments are type-compatible with its
814 opcode argument. The opcode should represent an operation
815 involving an operator. Also added the macro function
816 unop_type_check, which calls binop_type_check with a
817 NULL second argument.
818 expprint.c Added Modula-2 operators to the op_print_tab, so info
819 expression.h break works correctly. Also added "op_string", which
820 returns the string corresponding to the (enum exp_opcode)
821 opcode that is its argument.
824 Sat Jul 13 18:26:18 EDT 1991
826 coffread.c Added code to record the type of function arguments with
827 each paricular function. Code is very similar to that
829 dbxread.c Moved add_param_to_type() to symtab.c
830 symtab.[ch] Added function add_param_to_type() from dbxread.c
832 *** NOTE: The above additions have not been tested.
834 Mon Jul 15 12:50:47 EDT 1991
836 langauge.[ch] Added the functions type_error and range_error, which work
837 like error() except if the type/range mode is set to
838 *_mode_warn, then they do not do a return_to_top_level(),
839 but merely print a warning.
840 Also changed [set|show]_[type|range]_command() to support
841 the new "warn" feature.
843 Thu Jul 18 17:50:54 EDT 1991
845 mipsread.c Added code to record the type of function arguments with
846 each particular function. Code is very similar to that
849 *** NOTE: The above additions have not been tested.
851 Fri Jul 19 11:19:10 EDT 1991
853 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
854 UMIN_OF_SIZE, which when given a size of a numeric type,
855 return the maximum and minimum value it can hold. UMAX...
856 and UMIN... return the result for unsigned types.
857 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
858 struct types. They call above macros.
859 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
860 avoid a name conlict with the above.
861 c-exp.y Added range checking on numeric constants in
862 parse_number() for completeness.
863 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
864 return 0 if working_lang is not language_c.
866 Thu Aug 8 14:17:22 EDT 1991
870 breakpoint.c Documentation strings of some commands changed to
871 eliminate the references to the C language where
874 Tue Aug 13 15:48:03 EDT 1991
876 m2-exp.y Added qualified identifiers to the grammar. The semantics
877 are slightly different from those of the GDB operator ::
879 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
880 type_exp, where type_exp is any valid type expression.
882 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
883 printcmd.c Modified ptype_command() so it actually parses the input
884 (necessary for type expressions with scope qualifiers).
885 Added the function ptype_eval() which expects an
886 expression composed of one OP_TYPE element.
887 *.[ch] Replaced all occurences of parse_c_expression with
889 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
891 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
893 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
895 Small fixes from Peter Schauer:
897 * infrun.c (child_attach): Lint.
898 * solib.c (find_solib): Handle shared libs version 2.
900 Small fixes from David Wood:
902 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
906 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
907 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
909 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
910 chars_per_line is at maximum (user typed `set width 0'). Fix
911 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
913 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
915 * coredep.c: include ptrace.h where necessary.
916 * mipsread.c(parse_lines): fix unsigned char problem that was
917 messing up line numbers on SGI's and possibly other MIPS based
919 * infrun.c (child_create_inferior): use better test to check
920 return val from setpgrp().
921 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
922 for sgi/irix support.
924 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
926 * mipsread.c (parse_symbol): Put non-static procedures
929 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
931 Patch together `text_start' and `text_end' for 29K port.
933 * exec.c (exec_command): If NEED_TEXT_START_END, define the
934 variables and set them based on the exec file.
935 * am29k-tdep.c: declare text_start.
936 * valops.c (call_function_by_hand): declare text_end.
938 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
939 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
940 because machines that do this will also have to know to
941 set NEED_TEXT_START_END. Besides, it was a redundant way to
943 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
944 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
947 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
949 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
951 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
952 Pass MUNCH_DEFINE to munch whenever we run it.
953 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
954 format string; use 0x%x instead.
955 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
956 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
957 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
958 * inflow.c: Handle `short' process group IDs.
959 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
960 and check for ptrace errors.
961 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
962 (coff_symfile_init): Initialize text_bfd_scnum.
963 (read_coff_symtab): Use it to find the text [and absolute?] sections.
964 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
965 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
966 Merge target arm case with other "easy" cases. Add target
967 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
968 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
970 * minimon.h, remote-adapt.c, remote-mm.c: Add.
971 * munch: Cope with RT/PC putting fns in data segment.
972 Restore ability to override `nm' by specifying MUNCH_NM.
973 * xconfig/rtbsd, xconfig/ultra3: New host systems.
974 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
975 and remote-adapt. Remove encapsulated coff #define's (the
976 support should go in BFD, and gdb shouldn't know or care).
977 * tconfig/a29k-kern: Same, but for remote kernel debugging.
978 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
979 * tm-29k.h: Update BADMAG (though it should go away).
980 Allow the register definitions to be overridden in another
981 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
982 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
983 DUMMY_SAVE_GR96, for handling kernel calling conventions
984 that use GR64+ rather than GR96+.
985 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
986 remote debugging of Ultra3 kernel. Includes tm-29k.h and
987 overrides various things.
989 * remote-mm.c (mm_attach, mm_wait): Handle attach like
990 child_attach does, making a clean stop in the newly attached
994 * coffread.c: Make coffread independent of any particular
995 variant of COFF. Avoid #include-ing any particular one except
996 internalcoff.h. BFD now passes key values for symbol reading
997 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
998 and the symbol masks and shifts); use them.
999 Remove obsolete end_of_text_addr.
1001 * exec.c: Remove unused include files.
1003 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1005 * Makefile.in (documentation targets): Pass $(M4).
1006 Bugfix from eggert@twinsun.com (Paul Eggert).
1008 * stack.c (down_silently_command): Check for stack existence.
1010 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1012 * Makefile.in (VERSION): Update to 4.0.3.
1014 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1016 * core.c (core_file_command): Print frame at coredump with
1017 its level number, by calling print_stack_frame.
1018 * frame.h: Add selected_frame_level, print_stack_frame.
1019 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1020 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1021 Change print_sel_frame and print_selected_frame callers to
1024 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1025 * symfile.c (free_named_symtabs): Ditto.
1026 * main.c (main): wrap_here needs an arg.
1027 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1028 (solib_add): Avoid noise.
1029 (solib_create_inferior_hook): Lint.
1030 (sharedlibrary_command): Move dont_repeat to here.
1031 * utils.c (error): Call wrap_here to force buffered output.
1033 Small patches from Peter Schauer:
1035 * coffread.c (start_symtab): Free any existing line_vector before
1037 (read_coff_symtab): Ditto for type_vector.
1039 * source.c (lines_to_list): New variable, replacing function.
1040 (all uses): Use as variable.
1041 (_initialize_source): Add 'set listsize' and 'show listsize'.
1042 * utils.c (lines_to_list): Remove function.
1043 * stack.c (print_frame_info): Use as variable.
1044 * defs.h (lines_to_list): Remove declaration.
1046 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1048 * breakpoint.c (insert_breakpoints): Restore warning about
1049 the program might be running in another process, but only for
1050 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1051 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1053 * utils.c (error): if error_pre_print is set, print the string
1055 * main.c (main, print_gnu_advertisement, print_gdb_version):
1056 Reformat legalese so it always prints, but acts as an "I'm here"
1057 message while symbols are being read. If any errors occur,
1058 print a few newlines to set off the message and start it at the
1059 left margin. Remove mention of "help" command, and don't yak
1060 about symbol reading.
1061 (catch_errors): Error string is now printed first in case of
1063 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1064 suggest the "help" command.
1066 * Makefile.in (VERSION): Set to 4.0.2.
1068 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1070 * .gdbinit: Remove useless "rr" command. Set complaints
1071 to 1 for people debugging gdb.
1073 * breakpoint.c, remote-vx.c: Reword strings printed by
1074 catch_errors callers.
1076 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1078 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1079 (Fix from kenc@viewlogic.com.)
1081 Fix some infrastructure to be able to cope with host and target
1082 machines with different sized basic types (ints, ptrs, etc).
1083 (Idea from pierre@la.tce.com (Pierre Willard).)
1085 * values.c (value_from_longest): Rename from value_from_long.
1086 Handle pointer types as well as integers, so that targets with
1087 different pointer sizes from the host can be accomodated.
1088 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1089 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1090 uses of value_from_long to value_from_longest.
1091 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1092 the correct pointer type to value_from_long{est}.
1094 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1096 * remote-vx.c: Remove obsolete code for calling functions via
1097 vxworks kludge interface (it referenced value_from_long).
1099 * valops.c (value_string): Find malloc with lookup_misc_func, not
1102 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1104 Make writing to files work properly. (Fixes to BFD are also needed.)
1106 * core.c (core_open): Open file ourselves, read or r/w, depending on
1107 write_files. Use bfd_fdopenr.
1108 * gdbcore.h (write_files): New variable.
1109 * exec.c (write_files): Define variable, add set&show for it.
1110 (exec_file_command): Use write_files to open for read or r/write.
1112 Make shared library reading happen automatically. These changes
1113 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1115 * inferior.h (stop_soon_quietly): Add to exported variables.
1116 * infrun.c (child_create_inferior): call solib hook, if defined.
1117 (child_attach): call solib hook, if defined.
1118 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1119 (find_solib): Use lookup_misc_func rather than hand-rolled.
1120 (symbol_add_stub): New stub for catch_errors.
1121 (solib_add): Avoid output if !from_tty. Catch errors rather
1122 than just calling symbol_file_add and bombing.
1123 (solib_create_inferior_hook): Interface with the target process
1124 to let it read and alloc shared libs, then figure out what it did.
1126 * core.c (validate_files): Fix typo, soften warning.
1127 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1129 * utils.c (fputs_demangled): Avoid duplicate printing if
1130 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1132 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1133 (Fix from pierre@la.tce.com (Pierre Willard).)
1135 * main.c (catch_errors): Change argument to a char * from an int,
1136 since a char * can point to a struct full of glop, but an int
1137 is not guaranteed to be able to hold a pointer.
1138 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1139 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1140 * core.c (core_open, solib_add_stub): Adapt.
1141 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1143 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1145 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1146 by adding .NOEXPORT target.
1148 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1152 * Makefile.in (VERSION): Roll to 4.0.
1153 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1155 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1157 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1160 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1163 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1165 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1166 reflect above name change
1168 * WHATS.NEW: correct pointer to refcard.
1170 * doc/gdb.texinfo: update New Features, Installing
1172 * doc/gdbint.texinfo: add short description of configure +template
1174 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1176 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1178 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1180 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1181 tar file, add dependencies for referenced doc files.
1183 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1185 * coffread.c, symfile.c, stack.c: saberized.
1187 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1189 * doc/refcard.tex: permuted Essential Commands sec
1191 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1193 set/show symbol-reloading
1194 default set complaints 0
1196 RET-repeat disabled after prompted long displays
1197 processID (attach) interpretation of 2nd GDB cmdline arg
1199 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1201 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1202 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1203 breakpoint.c, main.c: lint.
1205 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1207 Install new configuration scheme for GDB and friends.
1209 * config.sub: Translate ordinary names to three-part names.
1210 * configure: Use three-part names internally.
1211 * configure.in: Translate three-part names to filenames.
1213 * README, WHATS.NEW: Update for gdb-4.0.
1214 * Makefile.in: Roll VERSION to 3.99.
1216 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1218 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1219 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1220 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1221 to single structures rather than arrays; when passing
1222 their address, use &. This avoids trouble with bdead compilers.
1223 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1224 instead. This avoids portability headaches.
1225 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1227 * source.c (open_source_file): Avoid ANSI const bdeath by
1228 skipping declaration and then casting result value.
1229 * tm-hp300bsd.h: Clarify comment.
1230 * utils.c (strstr): Result is const char *; ANSI bdeath.
1231 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1232 since system include file defines it differently from "defs.h",
1233 though the two are equivalent for our purposes.
1234 * tconfig/hp300bsd: Add m68k-tdep.o.
1236 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1238 * tconfig/sun*4: Remove warnings about system assembler.
1240 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1242 * mcheck.c: Avoid warning about undeclared abort fn.
1243 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1244 it causes recursive calls to error() when used in cleanups.
1245 To do so requires that we make it a function, so we do.
1246 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1247 * utils.c (do_cleanups): Remove the current cleanup from the
1248 chain *before* calling it, in case error() is called from it.
1249 The result won't be pretty, but won't be an infinite loop either.
1251 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1253 * dbxread.c (read_struct_type): Grok anon structs for C++.
1254 (vb_name, vptr_name): Null terminate these strings.
1256 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1258 Minor bug fixes from BSD Net2 gdb:
1260 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1261 returns 0, there is no previous frame.
1262 * breakpoint.c (commands_command): If !from_tty, don't call
1263 input_from_terminal_p().
1264 * dbxread.c (record_misc_function): Speed up slightly.
1265 (compare_psymbols): Ditto.
1266 * infcmd.c (do_registers_info): Take a second argument to
1267 determine whether to print float registers. "info registers"
1268 does not do so anymore. "info all-registers" does, now.
1269 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1271 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1272 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1276 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1277 executing_breakpoint_commands if we are interrupted by error.
1278 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1279 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1280 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1281 catch_errors() so we can setup the frame regardless of whether
1282 the shared libs work.
1283 * ieee-float.c (double_to_ieee_extended): Get exponent from
1284 right place in little-endian systems. From John Carey.
1286 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1288 * main.c: Remove unused terminating_signals and catch_termination().
1289 (long_options): Terminate with a zero element.
1290 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1291 (gdb_readline): Make call-compatible with readline.
1292 (init_signals): Improve comments re vfork vs. signal.
1294 * utils.c (prompt_for_continue): Use new gdb_readline().
1295 If we prompt for continuation, we don't let CR repeat the previous
1296 command, once we get back to a prompt. It's too easy to keep
1297 hitting CR, expecting "--more--" prompts, and have some long
1298 command start repeating on you.
1300 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1302 * blockframe.c (frameless_look_for_prologue): Speed up by
1303 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1304 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1305 Define two variants, one faster.
1306 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1307 and return zero, rather than giving an error.
1308 (setup_arbitrary_frame): Initialize the PC in the new frame.
1309 (skip_prologue): Add a second arg saying whether we're just
1310 checking for a frameless function or not.
1312 * core.c (core_open, core_close, core_xfer_memory): Move
1313 section table pointers and bfd* into the target_ops.
1314 (core_open): Allow errors in shared lib reading, etc.
1315 (core_files_info): Describe shared library sections.
1317 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1318 exec_files_info, set_section_command): Move section table
1319 pointers and bfd* into the target_ops.
1320 (add_to_section_table): Add BFD to section table.
1322 * target.c (target_xfer_memory, target_info): Pass target to
1323 xfer_memory and target_info functions.
1326 * gdbcore.h: Move struct section_table.
1327 * target.h: New home of struct section_table.
1329 * solib.c (solib_add): New argument is the target_ops whose
1330 section list is to be added to, if any. Reallocate the
1331 sections in that target to add any that come from shared libs.
1332 (throughout) so_sections renamed to sections.
1333 (solib_xfer_memory): Deleted.
1334 * tm-sunos.h (SOLIB_ADD): Add target argument.
1335 (SOLIB_XFER_MEMORY): Delete.
1337 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1338 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1339 from target_ops. It's the same on all targets. Add two section
1340 pointers to target_ops.
1342 * stack.c (find_relative_frame): Dump ancient algorithm for
1343 "down", just use handy "next" pointers.
1344 (frame_command): Don't error if there is no stack; let user
1347 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1348 modifies static state in the parent process; new_tty itself
1349 runs in the child and modifies the child's file descriptors
1350 to match the saved static state.
1351 * infrun.c (child_create_inferior): Call new_tty_prefork,
1354 * infptrace.c (child_xfer_memory): Add ignored target arg.
1355 * remote-eb.c (eb_xfer_inferior_memory): ''
1356 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1357 * remote-vx.c (vx_xfer_memory): ''
1358 * remote.c (remote_xfer_memory): ''. Rename from
1359 remote_xfer_inferior_memory.
1361 * main.c (main): Only try to attach "corefile" argument if
1362 it starts with a digit.
1364 * symfile.c (symbol_reloading): New "set/show" variable.
1365 (symbol_file_add): Shorten message about symbol reading.
1366 (add_symbol_file_command): Merge with add_syms_addr_command,
1367 since this should work on all targets now.
1368 (stop_whining): Default to zero, to shut up complaints
1369 about bad symbol tables on many systems.
1370 (free_named_symtabs): Just exit unless symbol_reloading.
1372 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1373 and add comment explaining shared library screw.
1375 * source.c: #if defined => #ifdef.
1377 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1379 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1381 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1383 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1384 (doc/Makefile knows how to make one for local config)
1386 * Makefile.in: use doc/Makefile for doc targets
1388 * doc/Makefile: GDB documentation now has its own Makefile
1389 doc/refcard.tex: renamed from "gdbrc.tex"
1390 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1391 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1394 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1396 * values.c (baseclass_addr): When reading target memory, use the
1397 length of the basetype, not the upper type. We've only malloc'd
1398 enough space for the basetype, leading to errors in free().
1400 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1401 ends up as a function specially, since we know the actual type of
1402 the pointed-to address. This (somewhat) fixes display of
1403 expressions that include misc_function_vector names. Try `cond 1
1404 !strcmp("a","b")' then `i b'.
1406 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1407 The child can be proceeded from inside wait_for_inferior in
1408 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1409 getting skipped in that case.
1411 * expprint.c (print_subexp): Use filtered output, since the
1412 subroutines we call use it, otherwise the output is horribly
1413 mangled, since output of wrappable stuff comes out late.
1415 * Makefile.in: Bump VERSION to 3.98.1
1417 * infrun.c (child_create_process): Use execlp to find the
1418 shell to exec our target program. This requires some fiddling
1419 with `environ' since there is no execlpe().
1421 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1423 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1424 Minor rearrangement of refcard permits two new make targets--
1425 gdbrc.dvi DVI output for refcard, using CM fonts
1426 gdbrc.ps PostScript refcard, using PS fonts
1428 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1432 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1433 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1435 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1437 * doc/gdb.texinfo: last changes for release.
1438 Minor typo and formatting fixes; incorporated most fixes remaining from
1439 filed mail commenting on earlier drafts.
1441 Added warnings: pipes don't work in run command;
1442 conditions are converse of assertions;
1443 step over fn without debug info goes to next fn;
1444 vars may have "wrong" values near fn entrance, exit
1446 Added example from Kingston on printing repeated nonadjacent values
1448 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1449 shell mode for signals
1451 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1452 doesn't sound so much like its parent "Stopping and Continuing"; also
1453 moved entries on continue to top of section, so they don't get lost.
1455 Improved installation directions in appendix, added manual formatting
1458 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1460 * configure.in: Remove xm.h and tm.h even if we aren't linking
1461 new ones, so "./configure sun4; ./configure none" does the right
1462 thing. Assume that alldeps.mak and depend are already built in
1463 srcdir, and avoid running "make" (particularly "make depend",
1464 which involves "gcc") from inside configure. Build Makefile
1465 directly rather than building Makefile.conf first.
1466 * configure: Regenerate with above changes.
1467 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1468 to 3.98. Revise gdb.tar.Z procedure to produce a file
1469 called gdb-$(VERSION).tar.Z but which unpacks into a
1470 directory called "gdb". Move non-source files out of
1471 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1472 (depend): Don't try to do "gcc expread.y".
1473 (expread.o): Update dependencies by hand.
1475 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1478 Fixed a variety of small typos that prevented info from formatting
1479 cleanly; altered too-long heading for GPL Appendix, as discussed
1480 w/RMS; Changed date on cover to July 91.
1482 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1485 (1) Applied some fixes due to comments from Larry Breed (easier ones
1486 through chapsec 5.2)
1487 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1488 it's broken in latest texinfo
1489 (3) Introduced *some* use of [] for optional arguments, where
1490 explanation is not simpler by listing cmd w arg and cmd w/out arg
1491 separately. Still not using @deffn.
1492 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1493 couple of headings are too long. Need patches to texinfo or revision
1496 * Partial update to README (which still needs work for this
1497 release!): (1) use of configure corrected for new script,
1498 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1500 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1502 * symtab.c (lookup_symbol): Don't complain right off about
1503 no debug symbols; use the misc function vector first.
1504 (list_symbols): Use misc function vector to find symbols
1505 that don't have debug info, and print them.
1506 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1507 PC range doesn't match symtab PC range, as it does on the
1508 MIPS because our symtab reading isn't perfect.
1510 * dbxread.c (dbx_symfile_read): Make warning about
1511 "no debug symbols" slightly nicer.
1513 * source.c (select_source_symtab): If "main" symbol exists,
1514 but decode_line_spec can't find line info, don't just return
1515 a zero; try other source symtabs or give an error.
1517 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1518 their low addresses first, then rip through fixing high addrs.
1520 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1521 <runene@ifi.uio.no>.
1522 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1524 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1526 * Minor, mostly mechanical, cleanup of doc subdir for clean
1527 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1528 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1530 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
1532 Mostly MIPS and general symbol-reading fixups.
1534 * doc/gdbint.texinfo: Add documentation on symbol-reading
1537 * mipsread.c: Remove kludges around #include "ecoff.h".
1538 Remove redefinitions of a_magic, etc, no longer used.
1539 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
1540 Fix global overview comments to match symfile.c protocol.
1541 (mipscoff_new_init): Eliminate cur_hdr if we have one.
1542 (mipscoff_symfile_read): Eliminate unused code. Avoid
1543 sorting all the symtabs, when all we have read here is psymtabs.
1544 The symtabs are sorted as they are created anyway. Tell
1545 condense_misc_bunches whether we're mainline.
1546 (psymtab_to_symtab_1): Pass filename when recursing, to make
1547 stack trace more informative.
1548 (parse_partial_symbols): Assume cur_hdr as argument.
1549 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
1550 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
1551 the TYPE_NAME of char *, since that's done in symfile.c.
1552 (free_numargs, parse_symbol, add_symbol, add_block,
1553 shrink_linetable): Declare these fns void.
1554 (upgrade_type): Convert tree of if's to switch. Clean up
1555 bogus "off == 0" handling with a complaint. Avoid setting
1556 field bitpos and bitsize of array with lower and upper bounds.
1557 Check specified bitsize of elements against their actual type's
1558 bitsize, and complain if different. Complain about unknown
1560 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
1561 (psymtab_to_symtab_1): Print names of subsidiary files that
1562 are being read in. FIXME, we read far too many files. This code
1563 is not the problem, the problem is in parse_fdr where the psymtabs
1565 (cross_ref): Result should indicate that we used one aux entry
1566 normally, or two if we encountered a "next" entry. This used
1567 to leave the caller pointing at the wrong aux entry.
1568 (add_symbol): If overflowed cur_block, reallocate it larger,
1569 chase all pointers to it, and complain(), rather than clobber memory.
1570 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
1571 (new_field): Only allocate one field initially, not two.
1572 Pull ++ out of macro argument. Simplify.
1573 (_initialize_mipsread): Avoid initialization of importd
1574 global_psymbols and static_psymbols.
1576 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
1577 to properly set pst->symtab; avoid searching for it.
1578 (symfile_fns): Improve comments, add a FIXME.
1579 * dbxread.c: Update comments to reflect symfile protocol.
1580 (read_ofile_symtab, end_symtab): Return the symtab.
1581 (psymtab_to_symtab_1): Set pst->symtab.
1583 * coffread.c (coff_symfile_read): tell condense_misc_bunches
1584 whether we're mainline.
1586 * symfile.h (sym_fns): Remove unused sym_discard member.
1587 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
1589 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
1590 the environment variable is not.
1591 * infcmd.c (finish_command): Use filtered printfs.
1592 * cplus-dem.c: Add struct tags to a few unnamed structs.
1593 * valops.c (value_coerce_array): Improve comments.
1594 * valprint.c (type_print_varspec_suffix): Print array size only
1595 if greater than zero.
1596 * m88k-tdep.c: Shift some lines left by one space, that had
1597 apparently been trashed at some point.
1598 * TODO: More things to do, a few got done.
1600 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1602 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
1603 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
1605 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
1606 * expread.y, findvar.c, symmisc.c: Ditto.
1607 * printcmd.c (address_info): Update printed forms of LOC_
1608 symbols. Elim LOC_EXTERNAL.
1609 (print_frame_args): Keep track of param stack offsets before
1610 re-looking up to find the local register param is kept in.
1612 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
1613 Further integration of mipsread into gdb. Eliminate unused
1614 routines, duplicate declarations. Handle static symbols in
1615 psymtabs as well as external symbols. When reading symtabs,
1616 insert symbols into the correct block (global, static, or a local
1618 (read_mips_symtab, parse_partial_symbols): Don't pass useless
1620 (mipscoff_symfile_read): Don't call select_source_symtab.
1621 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
1622 rather than SYMBOL_VALUE.
1623 (parse_external): Comment clobbering of top_stack.
1624 (parse_partial_symbols): Update comments. Allocate and parse
1625 static symbols as well as external symbols. FIXME, enum values
1626 are not handled in this pass, but should be. Inline new_psymbol.
1627 Use SYMBOL_VALUE_ADDRESS.
1628 (psymtab_to_symtab_1): Read symbols into global static block
1629 by default (until enter some function's local block context).
1630 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
1631 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
1633 * source.c (select_source_symtab): Select a source symtab
1634 from either the symtabs or, failing that, the psymtabs.
1635 (list_command): Update error message.
1636 (forward_search_command, reverse_search_command): Use getc, not
1637 fgetc, for speed. FIXME, add comment about buffers that die if
1638 overrun by long line.
1640 * values.c (unpack_field_as_long, modify_field): Avoid shifting
1641 by an entire word, which is not portable, if we have a 32-bit
1642 field. (Code in dbxread.c already turns such bitfields, if
1643 aligned, into ordinary ints, but fixing this will help for other
1644 symbol formats and for future changes.)
1645 * core.c (core_open): Handle ANSI const brain death.
1646 * utils.c (vprintf): Fix varargs typo.
1648 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1650 * findvar.c (find_var_value): Handle &function better.
1651 * TODO: Document work needed on &fn and &array.
1652 * printcmd.c (print_address_symbolic): New arg is the prefix
1653 to print if a name is printed.
1654 (print_address_demangle): Honor "set print address" now.
1655 Use new arg above to improve spacing of output.
1656 * valprint.c (val_print): When printing function pointers,
1657 print symbolic form too.
1658 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
1660 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1662 * core.c (memory_error): Reword error msg to mislead less.
1664 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
1666 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
1667 parse_partial_symbols): Use newer BFD internals (external_filehdr
1668 and external_aouthdr), byte-swap the fields that we care about
1669 before using them, and make the file header data local to
1670 read_the_mips_symtab rather than global.
1672 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
1674 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
1675 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
1677 * main.c (command_line_input): Flush stdout and stderr
1678 before every call to readline. This reportedly fixes a bug
1679 that comes up in Sys V running emacs-gdb and/or xxgdb,
1680 when stdin/out are pipes or sockets.
1682 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1684 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
1685 Avoid declaring Makefile dependencies, because GNU Make stupidly
1686 tries to update it if we do.
1688 * coffread.c: Revise for minor changes to bfd internal coff
1691 * configure: If -template= is given a relative path, make it
1692 absolute before recurring in subdirectories.
1694 * configure, configure.in, Makefile.in: Install "configure" script
1695 as replacement for config.gdb.
1696 * config.gdb, Makefile.dist, Makefile.sdir: Remove
1697 * README: Update for configure, mostly. FIXME.
1699 * Add dec3100 as equivalent to littlemips. Indicate in all host &
1700 target config files that they are for the host. When the lines
1701 get copied into the Makefile, this makes it more obvious what's
1704 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1706 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
1707 tabs, which end up in the disassembler output inadvertently.
1709 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1711 Make it compile cleanly in an ANSI GCC2 environment.
1713 * blockframe.c: <stdio.h>
1714 * cplus-dem.c: free takes a void *, ifdef __STDC__
1715 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
1717 * defs.h (alloca): Avoid doing anything if alloca already def'd.
1718 * stddef.h, stdlib.h: Remove these files.
1719 * symtab.c: Avoid declaring qsort, close.
1720 * symfile.c: Avoid declaring close.
1721 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
1722 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
1724 Assorted other changes.
1725 * dbxread.c: include "libaout.h", not "liba.out.h".
1726 * printcmd.c (print_frame_args): Set recurse properly for
1727 indentation of struct and array parameters.
1728 * valops.c (value_cast): Allow cast to void.
1729 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
1730 single_step() in a target-independent fashion.
1731 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
1732 set up to be ready to continue. This makes us target independent.
1733 * infptrace.c (child_resume): Remove call to single_step; now
1734 can single step a SPARC target of any kind.
1736 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1738 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
1739 docn into separate sections---basically chapters, plus two loose
1740 pieces that can be configured to go in different places. This
1741 allows GNU m4 to preprocess the manual without coredumping.
1743 * Makefile.dist: tell TeX where to find texinfo.
1745 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1747 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
1748 the new target "rdl-apps.texinfo" which captures the Makefile
1749 variable that records where to find the Readline libraries.
1751 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
1753 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
1754 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
1755 * defs.h (const, volatile): Only define if not already defined.
1756 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
1758 * README: Update for release 3.95.
1759 * config.gdb: Don't create readline dir in subdir builds.
1760 * main.c: Include with "..." form for non-system include files,
1761 so "gcc -MM" for "make depend" works.
1762 Include readline files with "...h" rather than <readline/...h>.
1763 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
1765 * coffread.c: Undo minor damage done by Rich Pixley. Use
1766 different internal and external representations of COFF
1767 data structures. Use new BFD routines for swapping them in and
1769 * symfile.c (free_named_symtabs): Avoid freeing file names that
1770 are null or empty. Old i960 tools seem to produce files that
1771 claim to have empty names, causing each successive file read
1772 to blow away the previous one.
1773 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
1774 Move deferred_stores to top of file, but don't separate its
1775 #define's from its variable. Add commentary.
1776 * Makefile.dist: Fix Rich damage; undo "configure" changes in
1777 favor of keeping the (working) config.gdb. Move readline
1780 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
1782 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
1784 * infptrace.c (fetch_registers): no result, since now void.
1785 * tconfig/news: target depends on m68k-tdep too.
1787 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1789 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
1792 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
1793 applied various small fixes due to or inspired by RMS comments
1795 * doc/gdb.texinfo: finished using all RMS comments, save those for
1796 appendices on readline and cmd history (which are in other source
1799 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1801 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
1802 chapter 9; (2) documented 'break' command's menu mode for
1803 overloaded names, in response to hgs problem report C++ p-31
1805 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1807 * doc/gdb.texinfo: (1) better introductory example; (2) more
1808 consistent use of @code, @samp, @file, @kbd throughout; small
1809 cleanups to first three nodes; (3) new "Contributors" node;
1810 (4) Appendix, Renamed Commands; (5) divert specialized startup
1811 instructions to "Targets" chapter for generic manuals, while
1812 leaving them up front for manuals specific to specialized
1813 environments; (6) apply fixes from RMS comments through chapter 4.
1815 * pretex.m4: modify explanatory text slightly (and redefine
1816 "regexp") to keep GNU m4 from complaining. (It still crashes
1817 later, but one step at a time...)
1819 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
1821 * readline/readline.c (update_line): Avoid dereferencing a pointer
1822 before comparing it to its bounds. Saber caught this.
1823 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
1824 and only set PC if tgetstr returned non-null. Saber caught this.
1826 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1828 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
1829 stuff for config manual) here where it counts; updated
1830 to use new subdir structure (gdb/doc/).
1832 * Makefile: generated from above via
1836 * gdbint.texinfo: added instructions on generating gdb.info* files
1837 locally for release. These are ordinary info
1838 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
1839 Makefile)---but due to use of texinfo 2, can't count on makeinfo
1840 to generate these, so we distribute them already formatted.
1842 * gdb.texinfo: included full Info node and menu crud (as generated
1843 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
1845 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
1846 put in comments-for-future gdb.info target (one day makeinfo will
1849 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1851 * gdb.texinfo: Updated to include new or old undocumented
1852 commands, at least the following (perhaps some others I forgot to
1853 record): info f, info float, info path, info program, info s, info
1854 set, info source, info terminal, info types, info user, set/show
1856 Also covered all recent GDB command renames for v4.
1858 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1860 * mipsread.c: Rather than keeping count of how many symtabs
1861 and psymtabs we have, for sorting purposes, count them when
1862 we need to sort. This fixes bug in rereading of symbol tables.
1864 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1866 * infcmd.c: renamed "info path" to "show paths"
1867 * gdbrc.tex: documented above.
1869 Wed May 8 04:51:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1871 * remote.c: Fix comments.
1872 * utils.c (error): Force out any pending wrap output.
1874 Sat May 4 11:11:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1876 * Makefile.dist: Roll VERSION to 3.95.
1877 Fix up "saber_gdb" to work again.
1878 * saber.suppress: Update.
1880 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
1881 symtab.h, target.c, target.h: Lint.
1882 * core.c: setup and select frame after reading shared libs,
1883 else reading shared libs will clobber them. Lint.
1884 * utils.c (error): Force out any buffered wrap text.
1886 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1888 * remote.c: Remove decls of memory_insert_breakpoint
1889 and memory_remove_breakpoint, no longer used. (Suggestion of
1892 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
1893 to make it easier to interface to "configure"'d libraries.
1895 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
1897 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
1898 aliases for set/show print.
1900 Thu May 2 11:22:02 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

1926 {unpack_,value_as_}long (for now anyway).
1928 * m88k-tdep.c (get_saved_register): Make get_reg a dc_word_t (*)().
1929 (psr_register): Change return type to dc_word_t.

1937 * tm-88k.h, m88k-tdep.c: Make stack_error, stack_jmp global.
1938 m88k-xdep.c: Don't mention stack_error.
1940 * {x,t}config/m88k ({X,T}DEPFILES): Add missing files.
1942 * mtrace.c: Don't typedef things like size_t, just #define them.
1944 * coffread.c [TDESC]: #if 0 out references to coffsyn.
1946 * symtab.h (struct symtab): Include EXTRA_SYMTAB_INFO.
1947 tm-88k.h: Define EXTRA_SYMTAB_INFO.
1949 * coffread.c [TDESC]: Include "tdesc.h" and make tdesc_handle
1950 dc_dcontext_t not int.
1952 * coffread.c [TDESC]: Use system include files not <intel-coff.h>.
1954 * coffread.c [TDESC]: Move setting of debug_info from
1955 coff_symfile_read to find_linenos and make it work with BFD.
1957 * cplus-dem.c [__STDC__]: Make x{m,re}alloc return void*.
1959 * signame.c: Cast const char* to char* when assigning to sys_siglist.
1961 * utils.c (strsave): Make arg const char* not char*.
1963 * infrun.c (wait_for_inferior) [SHIFT_INSN_REGS]: Use
1964 bpstat_explains_signal (stop_bpstat) not stop_breakpoint.
1966 * tm-88k.h (START_INFERIOR_HOOK): Make tdesc_handle a dc_handle_t.

1982 Thu May 2 17:53:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1984 Mips bringup and general cleanup
1986 * cplus-dem.c: Move CPLUS_MARKER define to after defs.h.
1987 * infptrace.c (PT_WRITE_D, PT_READ_D): Use correct values.
1988 (This still doesn't seem to make MIPS bkpts work.)

2453 new psymtab for it has been read.
2454 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
2455 a file, once a new symtab has been read for it.
2456 * mipsread.c: FIXME. We need to do the same for MIPS, but it
2457 looks harder to determine the top-level block before it's been
2458 queued to the psymtab list.
2460 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
2461 If we have wiped out any old symbol tables, clean up at end of
2463 (symbol_file_command): Don't reference symfile_fns if it's zero.
2465 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
2466 defines for the blocks of a blockvector that contain global and
2467 file-static symbols and the first of the smaller scope contours.
2468 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
2469 decode_line_1, make_symbol_completion_list): Use the above.
2470 * coffread.c (end_symtab, patch_opaque_types): Ditto.
2471 * dbxread.c (end_symtab): Ditto.
2472 * expread.y (block): Ditto.
2473 * mipsread.c (throughout): Ditto.
2474 * symmisc.c (free_named_symtabs): Ditto.
2476 * symtab.c (list_symbols): Process the first symbol of the
2477 static psymbols list.
2478 (types_info): Restore this function from its untimely #if 0.
2479 It's not perfect, but it is better than nothing.
2480 (_initialize_symtab): Restore "info types".
2482 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2484 * m68k-stub.c: Remote stub for 680x0's, created from
2485 rem-m68k.shar (which is removed).
2486 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
2487 Remove RCS log stuff now that we use CVS and it blows our diffs.
2489 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2491 * symmisc.c (free_named_symtab): Make it work, in its current
2492 kludgy fashion. Change result to indicate if we blew away bkpts.
2493 * dbxread.c (end_symtab): Accumulate result from
2494 free_named_symtab and print warning if we blew user's state.
2495 * symfile.h: free_named_symtab now returns an int.
2497 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
2499 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
2500 is the first symbol read, even if not mainline.
2501 (dbx_psymtab_to_symtab): symfile might be zero, cope.
2502 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
2503 (set_section_command): New command ("section xxx yyy" -- should
2504 be renamed to "set section xxx yyy" FIXME) which sets the
2505 base address of a section of the exec file, overriding the
2506 virtual address that BFD reports.
2508 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2510 * exec.c: Add add_syms_addr_command to exec_ops, so you can
2511 load symbols at any address while examining an exec file.
2513 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2515 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
2516 for printing the float info is host-dependent, not
2517 target-dependent. FIXME.
2518 * i386-pinsn.c: Move #includes to top, remove useless ones.
2519 * i386-tdep.c: Don't bother including <.../reg.h> since we
2520 don't use it (and it doesn't exist on host systems).
2522 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
2523 Convert negative numbers properly.
2524 (ieee_test): Make numbers really random; fix format arg.
2526 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
2527 * core.c (core_detach): Unpush core_ops, which might not be on
2528 top. We used to just pop the top, which broke things. Don't
2529 need dont_repeat() any more.
2530 (core_file_command): Psst! Don't repeat it.
2531 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
2532 * expprint.c (print_subexp): Avoid switch fallthru on
2533 BINOP_ASSIGN_MODIFY, so we can print += and such.
2534 * frame.h: Fix typo.
2535 * inflow.c (kill_command): After killing inferior, print our
2536 current frame in the core file, if we have one.
2537 (generic_mourn_inferior): When inferior dies, either select
2538 the current frame (in the new target, e.g. core file), or
2539 set both the current and selected frames to NULL.
2541 Changes from Peter Schauer.
2543 * infptrace.c: Avoid <sys/ptrace.h> on USG.
2545 * Make all file names fit in 14 characters (sigh and damn!):
2546 mv hp300hpux-xdep.c hp300ux-xdep.c
2547 mv symmetry-xdep.c symm-xdep.c
2548 mv symmetry-tdep.c symm-tdep.c
2549 mv convex-opcode.h convx-opcode.h
2550 mv tm-vxworks960.h tm-vx960.h
2551 mv tm-vxworks68.h tm-vx68.h
2552 mv Makefile.srcdir Makefile.sdir
2553 mv gdb-int.texinfo gdbint.texinfo
2554 mv remote-sa.m68k.shar rem-m68k.shar
2555 mv remote-multi.shar rem-multi.shar
2556 * Makefile.dist, README, config.gdb, convex-pinsn.c,
2557 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
2558 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
2561 * command.c (user_info_1, user_info): New command for listing
2562 the user-defined commands.
2564 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2566 * dbxread.c (really_free_pendings): Clear file_symbols
2567 and global_symbols after freeing them; otherwise, running
2568 this function twice (if it appears twice on the cleanup
2569 chain), we try to free things twice.
2571 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
2572 based on text_addr (the address of text in core), not on addr (the
2573 offset between text in the .o file and in core). This change
2574 is from Peter Schauer.
2576 * main.c: Define ALL_CLEANUPS as a cast of zero.
2577 (return_to_top_level): Use it.
2578 (main): Do all cleanups after each command run as part
2579 of the gdb startup sequence. Also do all cleanups before
2580 entering the command loop, and every time we exit the command
2581 loop and reenter. Before, the cleanups from the startup sequence
2582 were being left undone until the first error!
2583 (command_loop): Rename do_nothing cleanup to command_loop_marker
2584 so we can see it easily when examining the cleanup chain.
2585 (init_signals): Add another do_nothing for signal handling.
2586 (quit_command): Only try to kill target if it has execution.
2587 Problems in the target stack got us into a state where
2588 inferior_pid was nonzero but none of the targets had execution.
2589 In this state you couldn't exit gdb.
2591 * dbxread.c: Two changes from Peter Schauer.
2592 (echo_command): Fflush output after an echo command.
2593 (show_history): Pass all args to cmd_show_list.
2595 * utils.c (init_malloc): Call mtrace to turn on tracing
2596 if the environment variable MALLOC_TRACE is set to a file name.
2597 * mtrace.c: Add source file which provides a log of every malloc,
2598 free, and realloc to a trace file.
2599 * mtrace.awk: Add source file which analyzes the trace file.
2600 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
2601 (VERSION): Roll to 3.94.3.
2603 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
2604 (check_duplicates): Don't bother with watchpoints.
2605 (set_raw_breakpoint): Comment about danger of this routine.
2606 (watch_command): Parse and eval all args before calling
2609 * solib.c (find_solib): Avoid error in referencing memory to
2610 see if any more shared libraries have been added. This is
2611 particularly useful if the target has terminated. Bug reported
2614 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
2615 in bringing up 3.94.2 on the Sun-3.
2617 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
2618 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
2619 expression (in scope) before reenabling watchpoint.
2620 * signame.c (init_sigs): Add missing declaration of i, fix
2621 sys_siglist declaration.
2622 * source.c (list_command): Fixed range computation to use
2624 * stack.c (backtrace_command): Do not allow command if target has
2625 no stack, print informative error message.
2626 * target.c (target_command): Do not write into command line
2627 because this fails if the target command is used in a user defined
2628 command. [This change was enhanced by gnu to support any-
2629 unique-prefix matching on target names.]
2630 * valops.c (value_struct_elt): Avoid infinite loop on an
2631 erroneous attempt to print the member of function (try p main.p).
2633 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2635 * expread.y (name_no_typename): Avoid reduce/reduce errors
2636 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
2637 Since the GDB parser really doesn't use name_no_typename in a
2638 name-only context, the parser can't tell the diff between
2639 names and numbers here. Avoid allowing a name_no_typename
2640 to be a NAME_OR_*INT to resolve the conflict.
2642 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2644 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
2646 * valprint.c (val_print_fields): bitfield printing didn't handle
2647 byte order. Indirect through a few more fns to cope.
2649 * values.c (modify_field): also cope with byte order.
2651 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2653 Cleanup for release 3.94.2:
2655 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
2656 include files. Roll version to 3.94.2.
2658 * coffread.c (init_stringtab): Read length into unsigned char
2659 array before swapping; don't assume 32-bit longs.
2661 * target.c (target_info): Don't bother with get_sym_file, just use
2662 the symfile global variable.
2663 * symtab.h, symfile.c (get_sym_file): Delete it.
2665 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
2666 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
2667 (read_type): Replace one more error() with complain().
2669 * mipsread.c (parse_partial_symbols): Replace printf with complain.
2671 * i960-tdep.c: Fix copyright attribution.
2673 * config.gdb: Quote all backquotes in doublequotes. You can
2674 quote me on that. BSD 4.4 shell found this one.
2676 * infptrace.c (throughout): The third argument to ptrace is an
2679 * infrun.c (wait_for_inferior): When program has terminated, we
2680 have to call target_terminal_ours before we pop that target off
2681 the stack (e.g. before a call to target_kill or
2682 target_mourn_inferior). This fixes problem where a program
2683 terminates, then GDB stops for (tty output) and you have to type
2684 "fg" to the shell to resume it. FIXME: This code for what to
2685 do after termination really should be in normal_stop instead.
2687 * gdbcore.h (read_memory_check): Change declaration; it changed
2690 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
2691 4.4 prereleases, this avoids a bug in their sgtty compatability
2693 * remote.c: Use terminal.h rather than hand-rolling the same.
2695 * signame.c, signame.h (psignal): Arg is unsigned, not int.
2696 * utils.c (strsave, strstr): Fix arg types.
2697 * valprint.c (val_print): lint
2699 MIPS symbol table support from Per Bothner:
2701 * symfile.c (symtab_fns): Remove initializer table that needs to
2702 be hacked for each new symbol file format supported.
2703 (add_symtab_fns): New function, chains symbol table
2704 handlers into the global list.
2705 (symfile_init): Search this list.
2706 * symfile.h: Add next pointer, declare add_symtab_fns.
2707 * coffread.c (_initialize_coffread): Call add_symtab_fns.
2708 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
2710 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
2711 symbol *). Thus, we no longer need the hack to trash
2712 pst->filename. Good, since that hack confused code in symfile.c!
2714 (reorder_symtabs, destroy_all_symtabs): Removed static
2715 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
2716 Instead, the latter now uses a temporary array (stack-allocated
2717 from an obstack, and then freed).
2719 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
2720 haven't been set in the outermost stBlock of a procedure. This was
2721 a problem with f77 binaries on Ultrix 4.?.
2723 (new_symtab, new_symbol, new_type): Continue changing code to use
2724 obstacks more and otherwise conform to dbxread internal style.
2725 Made the free_code of symtabs be free_linetable (as in dbxread)
2726 instead of free_contents. This implies memory leaks when reading
2727 a new symbol table, until the conversion is finished. Did change
2728 (struct symbol) and (struct type) to be allocated on the
2729 symbol_obstack. Blocks and blockvectors are among the things
2732 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
2733 tested much, but it solved one problem (reported by Meissner), and
2734 cleans up some other things. The problem happened when an
2735 included file contains actual code (functions) and not just
2736 definitions. The mips coff is a little inconvenient there, since
2737 it may cause a procedure to be mapped to the wrong psymtab.
2739 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
2740 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
2741 this will need work for the new core paradigm.
2743 Opcode patches from the net:
2745 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
2746 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
2747 missing altogether - they are added here. From Bruce Bauman.
2748 * mips-opcode.h: The low mask for C0 instructions was too small.
2749 From Garrett Lau. I modified the fix to check the entire 32-bit
2752 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
2755 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2757 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
2759 * dbxread.c (read_type): Pointer subtraction (value_sub in
2760 valarith.c) sometimes failed because the types of the
2761 pointers being subtracted were not identical.
2762 These differed because dbxread.c was allocating pointer types
2763 using dbx_alloc_type+smash_to_pointer_type instead of
2764 lookup_pointer_type. I failed to find a justification for the
2765 former, so I changed it to use the latter. Similarly, I
2766 replaced smash_to_function_type by lookup_function_type,
2767 and smash_to_reference_type by lookup_reference_type.
2769 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
2770 _initialize_mipsread): corresponding changes.
2772 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
2774 * source.c (mod_path): Do tilde_expand on each component of the path,
2775 rather than on the (list of) paths as a whole.
2776 (print_source_lines): Set first_line_listed in addition to
2777 current_source_symtab and current_source_line. If the source was
2778 not findable, after a "dir" command to fix the problem,
2779 a "list" would get the wrong lines.
2781 While I was there... (gnu):
2783 * dbxread.c (read_type): Change error to complaint.
2785 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2787 First attempt at detailed understanding of symbol table memory alloc.
2789 * dbxread.c (dbx_symfile_read): Free our string table if we
2790 aren't the mainline. Free the "info" struct since we're done with
2792 (init_psymbol_list): Free any previously allocated psymbol lists.
2793 (): FIXME: Should realloc-down the psymbol lists when done reading
2794 the main symbol file?
2796 * symmisc.c (free_symtab): Free fullname field too.
2798 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
2799 (REGISTER_ADDR): Make result type unsigned int.
2801 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
2802 define REGEX must also define REGEX1 (its dependency).
2804 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2806 * tconfig/i960: No longer works, points you at vxworks960 or
2809 * xgdb.c, XGDB-README: Remove file. Users can get the much
2811 * Makefile.dist: Remove all trace of xgdb.
2813 * breakpoint.c (breakpoint_1): Pass demangle arg to
2814 print_address_symbolic.
2815 (clear_breakpoints): Remove unused function.
2816 (breakpoint_re_set_one): Guts of breakpoint_re_set.
2817 (breakpoint_re_set): Use catch_errors to do them all anyway.
2819 * gdb-int.texinfo (Host versus Target): Add section on what is
2820 a "host" feature versus what is a "target" feature.
2822 * infcmd.c (path_command, path_info): Handle the PATH variable
2823 (object search path) as conveniently as the source search path.
2824 * environ.c (set_in_environ): Set some vars in GDB's environment,
2825 in addition to the child's. PATH, G960BASE, G960BIN for starters.
2826 * source.c (mod_path): New function, from guts of
2827 directory_command, modifies a path. Used by path_command.
2828 (directory_command): Call it.
2829 * defs.h (strsave): Declare.
2831 * utils.c (sevenbit_strings): Add new printing option.
2832 (printchar): Use it.
2833 (strsave): Provide this handy helper routine.
2834 (set_width_command): Rename set_screen_width_command.
2835 (_initialize_utils): "set screen-width" => "set width";
2836 "set screen-height" => "set height"; add sevenbit-strings.
2838 * infcmd.c (do_registers_info): Print floating point registers
2839 in raw hex as well as float format, regardless of whether it is
2840 a "virtual" convertible register.
2841 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
2842 regs as a double, just in case it's being used that way.
2843 * values.c (unpack_long): Comment on array/function coercion.
2844 (unpack_double): Argument is in target byte order now. For
2845 integer arguments, just call unpack_long and float the result.
2846 * m68k-tdep.c: include defs.h for "const" handling.
2847 * remote-nindy.c: Use ieee-float stuff.
2848 (nindy_fetch_registers): Unpack double regs to host double, then
2850 (nindy_store_registers): Pack extendeds to host double, flip
2851 around by misusing unpack_double, send as target double.
2853 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
2854 zero, as when stopped at the first instruction of a process.
2856 * blockframe.c: Fix filename in comment (param.h => tm.h).
2857 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
2858 * tm-68k.h: Fix typos.
2860 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
2862 Changes from a bringup on the DEC Vax under Ultrix 4.0.
2864 * coredep.c (fetch_core_registers): Pass end-address of register
2865 section to register_addr as expected. Don't call supply_register
2866 if we'd just pass it garbage.
2868 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
2870 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
2872 * target.c (push_target, target_info): Cast enums to int for < or
2875 * stack.c (print_frame_info): Identify source file & line
2876 even if we can't print it.
2878 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
2880 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
2882 Clean up IEEE floating point support.
2884 * ieee-float.h: New file.
2885 * ieee-float.c: Write real routines to convert between host
2886 doubles and various target IEEE extendeds.
2887 * m68k-xdep.c: Eliminate assembler code for extended floats.
2888 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
2889 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
2890 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
2891 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
2892 double_to_ieee_extended.
2893 * i960-tdep.c: Define ext_format_i960.
2894 * m68k-tdep.c: Define ext_format_68881.
2895 * sparc-tdep.c: Define ext_format_sparc, though unused.
2896 * Makefile.dist (HFILES): Add ieee-float.h.
2897 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
2900 Obsolete the "coffstrip" program in favor of using BFD's strip.
2902 * nindy-share/coffstrip.c: Remove file.
2903 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
2904 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
2905 * tconfig/nindy960: Remove reference to coffstrip.o.
2907 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
2909 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2911 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
2912 * dbxread.c: Remove static symfile_bfd.
2913 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
2915 * inftarg.c (child_detach): Pop the child_ops vector if the
2916 detach is successful.
2917 * remote-nindy.c (nindy_create_inferior): Don't push a new
2918 nindy_ops since nindy uses the same one for execution and memory
2920 * core.c (core_ops): Use child_attach and child_create_inferior
2921 rather than default attach and create_inferior functions.
2923 Handle floating point registers in core files.
2925 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
2926 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
2927 This version untested since BFD doesn't yet support sun3 core
2929 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
2930 conventions. Fix comments and style. This version has not
2931 been compiled yet, since we have no HP inhouse.
2932 * core.c (get_core_registers): Look for two sections, ".reg"
2933 and ".reg2", and pass both to fetch_core_registers sequentially.
2935 Revise directory path yet again.
2937 * source.c (forget_cached_source_info): Not static any more.
2938 (init_source_path): New default source path is "$cdir:$cwd".
2939 (dir_command): Handle variable arguments ($cdir, $cwd).
2940 (source_info): Print "Compilation directory" rather than
2941 "Originally compiled in" to remind people of $cdir.
2942 (openp): If the path contains $cwd, use current directory.
2943 (open_source_file): If compilation directory is known, replace
2944 first $cdir in path with the compilation directory.
2945 (print_source_lines): Even if we can't print the lines, set the
2946 current symtab and line for future commands like "info source" or
2947 "breakpoint". Also, error message now contains the file name,
2948 line number, and file access error message.
2949 (_initialize_source): Fix help text to describe changes.
2950 * main.c (cd_command): Forget cached source info when we chdir.
2951 * utils.c (strstr): Add simple implementation.
2953 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
2955 * coffread.c (read_one_sym, init_linetable, init_stringtab):
2956 Byte-swap COFF symbol tables if necessary when reading them in.
2957 Use complain() to replace error message in one spot. Needs
2958 corresponding change in bfd/coff-code.h to make some symbol
2959 swapping routines non-static.
2961 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
2963 Merge changes from Eirik Fuller, for UTek.
2965 * defs.h (errno): Add declaration.
2966 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
2967 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
2968 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
2969 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
2970 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
2971 declarations of errno.
2973 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
2975 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
2976 <rpc/rpc.h> and <rpc/types.h>.
2978 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
2980 * i960-tdep.c (examine_prologue): Add new argument limit,
2981 which stops the scan at the end of the prologue, or at the PC.
2982 This fixes a problem where it walks down into the code for the
2983 user's statements if that code looks like function prologues.
2984 Mark Fox and I have been bouncing this code back and forth, making
2985 small changes to it. Callers changed to match.
2987 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
2989 Cleanup for gdb-3.94 release final:
2991 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
2992 the .c files from vx-share and nindy-share, from the various
2993 macros, since they are not found via ALLDEPFILES.
2994 (SFILES): Add tm-i960.h.
2995 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
2996 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
2998 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
2999 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
3001 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
3003 * am29k-tdep.c: Add contribution line.
3004 (examine_prologue): Cache information about function prologues in
3005 the misc-function-vector to avoid lots of references over the
3006 serial line while examining instructions.
3008 * core.c (core_close): New function made from cleanup_core.
3010 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3011 remote-vx.c, remote.c, target.c, target.h,
3012 Update target_ops vector to add attach, close, and load entries.
3013 Use add_syms_addr_command, not add_file_addr_command, for
3014 add_file. Break out close routine from existing code.
3016 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3017 they are in an obstack.
3018 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3020 (define_symbol): Add symbol type parameter; change callers;
3021 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3022 it to influence the symbol class on the i960.
3023 (define_symbol): Swap LOC_CONST's into target byte order.
3025 * exec.c (exec_close): New function.
3026 (exec_file_command): Call it.
3028 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3029 Fix byte order of frame pointer.
3030 (read_var_value): Result of 0 if var's value can't be found,
3031 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3032 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3033 (locate_var_value): Use read_var_value and use its lazy address
3034 as the location of the var's value. Lint.
3036 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3039 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3040 obsolete Intel versions in favor of vxgdb versions.
3041 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3042 code dealing with byte order of values, which Intel did in host byte
3043 order rather than gdb-4's target byte order.
3044 (i960_frame_chain_valid): Move to nindy-tdep.c.
3045 (examine_prologue, skip_prologue, frame_find_saved_regs,
3046 frame_args_address, leafproc_return, saved_pc_after_call,
3047 pop_frame): Add vxgdb versions from Mark Fox.
3048 (examine_prologue, frame_struct_result_address): Add code
3049 to deal with the saved value of G13 (struct return address
3051 (frame_args_address): Modify Mark's version to prefer the
3052 saved value over the current value in the topmost frame.
3053 Cache result in the frame info to avoid performance hair in
3055 (print_fault): Add gdb960 code for printing faults.
3056 (_initialize_i960): Actually call check_host.
3058 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3059 add stub routines. FIXME, these currently just return zero!
3061 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3062 (attach_command): Call target_attach, not target_open, now.
3064 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3065 (child_attach): Rename from child_open.
3066 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3067 don't confuse it with a zero step_resume_break_address.
3069 * inftarg.c (child_detach): Eliminate inferior_pid test.
3070 (child_files_info): Clean up message a bit.
3071 (child_ops): Use child_attach, not child_open, to attach.
3073 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3074 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3075 findvar.c to here, since it depends on the contents of the
3076 shadow_contents of breakpoints, but keep if #if 0 since it is
3079 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3082 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3083 (ptype_command, display_command): Eliminate have_inferior_p and
3084 have_core_file_p in favor of target_has_stack or
3085 target_has_execution.
3086 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3087 code for actually finding the values of arguments, though we still
3088 keep track of the maximum stack offset for use in printing unnamed
3089 arguments. Handle missing FRAME_ARGS_ADDRESS.
3091 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3092 (struct nindy_regs): Define registers passed to/from nindy.
3093 (nindy_fetch_registers, nindy_store-registers): Translate between
3094 nindy and GDB formats for the registers.
3095 (dcache_init): Statically allocate the cache, since it was being
3096 allocated by a malloc that was never freed anyway.
3097 (nindy_create_inferior): Error, not core dump, if no exec file.
3098 (nindy_before_main_loop): Use target_load, not target_add_file.
3100 * remote-vx.c (net_load): Specify large timeout for load
3101 requests. Allow user to break out with INTERRUPT.
3102 (net_break): Remove useless code, clean up. Change callers.
3103 (parse-args, skip_white_space, find_white_space): Clean up arg
3104 parsing to cope with quoted strings.
3105 (net_wait, net_quit): Never call error, just return status.
3106 (vx_read_register, vx_write_register): Cleanup status checking.
3107 #ifdef the code based on which CPU we are using (960 or 68k),
3108 FIXME, this should be completely general but it isn't yet.
3109 (vx_xfer_memory, vx_resume): Cleanup status checking.
3110 (vx_run_files_info): Improve message.
3111 (vx_load_command): Renamed from vx_add_file_command. Allow load
3113 (net_ptrace): Remove unused routine.
3114 (vx_wait): Adopt code from vxgdb960 to cope with broken
3115 connections to target machine and prompt to disconnect. Remove
3116 debug printouts. Map some EVENT_'s to SIGnals.
3117 (add_symbol_stub, vx_open): Print names of object files we found,
3118 and "ok" if we read their symbols OK. Clarify output in general.
3119 (vx_attach, vx_detach, vx_kill): Add these commands.
3120 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3121 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3122 "info files" output, and create_inferior, since we already have
3125 * stack.c (frame_info): Replace Frame_unknown with 0.
3126 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3127 (return_command): Pop until the PC matches as well as the FP,
3128 so it works even if the FP is shared with another function,
3129 as in "frameless" or "leaf" procedures.
3131 * symfile.c (load_command): renamed from add_file_target_command.
3132 (add_syms_addr_command): renamed from add_file_addr_command.
3133 (add_syms_command): Stub to call target_add_syms.
3134 (_initialize_symfile): Change command names and descriptions,
3135 add-file => add-syms, and load from alias to its own command.
3137 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3138 maybe_kill_then_create_inferior): Default for attempts to start
3139 a process, if one is already running, is to ask about killing
3140 it and retry if yes.
3141 (upstack_create_inferior): #if-0 it, strata obsolete it.
3142 (push_target, unpush_target, pop_target): to_close() a target
3143 before unstacking it.
3144 (target_info): Renamed from target_files_info.
3145 (_initialize_targets): Rename "i files" as "i target", accessible
3148 * target.h: Improve comments about the target_ vectored routines.
3150 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3151 Convert commenting style to standard GNU style.
3152 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3153 (SKIP_PROLOGUE): No longer a no-op.
3154 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3155 (*_REGNUM): Sort register numbers.
3156 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3157 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3158 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3159 are now 10 byte extendeds, not 8 byte doubles.
3160 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3161 for nindy versus vxworks targets. FIXME, this should possibly go
3162 in the target vector.
3163 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3164 frame_saved_regs and arg pointer with each frame.
3165 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3166 (FRAME_ARGS_ADDRESS): Use cached result.
3167 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3168 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3169 (PRINT_RAMDON_SIGNAL): Call print_fault.
3170 (POP_FRAME): Now works.
3172 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3173 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3174 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3175 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3178 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3179 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3181 * valarith.c (value_subscripted_rvalue): Avoid handling
3182 floats and doubles specially; it gave alignment errors. Lint.
3184 * valops.c (value_of_variable, value_of_this): Error if unknown
3187 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3188 to avoid alignment problems.
3189 (value_print): Handle unknown value address.
3190 (cplus_val_print): Two args are ignored; remove them. Change caller.
3191 (val_print): Use unpack_long rather than pointer-deref.
3194 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3195 to avoid alignment problems.
3196 (value_being_returned): Error if return value unknown.
3197 (set_return_value): Add bogosity warning, FIXME. *
3199 * TODO: A woman's work is never done.
3201 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3202 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3203 Add ieee-float.o to OBS.
3204 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3205 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3206 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3208 Changes to generalize the VxWorks RPC protocol slightly, to handle
3209 i960 as well as 68000.
3211 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3212 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3213 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3214 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3215 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3216 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3217 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3218 so they will move in target byte order rather than network
3219 byte order (happens to be the same).
3221 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3223 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3225 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3228 Add contribution lines to various files, showing where they
3231 * breakpoint.c (break_insn, check_break_insn_size,
3232 read_memory_nobpt): Remove to mem-break.c.
3234 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3237 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3238 entry has bad register number. This change is not
3239 tested in this release, FIXME.
3241 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3244 * value.h: Force value's contents field to be aligned to hold
3245 at least a double or a long long (if supported). This avoids
3246 doing bcopy's in and out of the contents field.
3248 (step_1): Avoid coredump under obscure circumstances when we
3251 * symtab.h (misc_info): Add field to misc function vector for
3252 any kind of cached information the target code desires. AMD
3253 29000 uses this to avoid repeating examine_function_prologue's.
3255 * coffread.c: Lint. Remove static symfile, read_section_header.
3256 core.c (have_core_file_p): Lint: remove.
3257 expprint.c (print_subexp): Lint.
3258 infptrace.c, valops.c, valprint.c: lint.
3260 Roll in changes from vxgdb-5.0.1:
3262 * symtab.h: Comment byte order of each address class. Add
3263 LOC_LOCAL_ARG for frame-relative args (960).
3264 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3265 symtab.c, symmisc.c: ditto.
3267 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3269 * remote.c (remote_resume): Error if resume with a signal.
3271 * symfile.c (prim_record_misc_function): Clear misc_info.
3272 (fill_in_vptr_fieldno): Check stub type of arg.
3274 * valops.c (value_cast): Avoid looking up names of types whose
3275 name we don't know, to prevent coredump. Sun CC produces typedef
3276 rtx and the name of *rtx is zero...
3278 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3280 Roll in changes from final AMD 29000 port (Tiemann).
3282 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3283 for ../include/a.out.encap.h. This might not work now that BFD
3284 is separately compiled. Instead, BFD support for encap will have
3285 to translate machine type 29k into the right COFF_MAGIC.
3287 * infcmd.c: Remove references to inferior_pid that aren't used
3288 in actual ptrace calls; use target_has_execution, etc.
3289 (have_inferior_p): Remove function.
3290 (program_info): Print target info rather than "process number";
3291 avoid gratuitous messages unless from_tty.
3292 (run_stack_dummy, finish_command): Set proceed_to_finish.
3293 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3294 main.c: Lint. Lose have_inferior_p().
3295 inferior.h (have_inferior_p): Remove, lint.
3296 (proceed_to_finish): Add flag to ask that all regs be saved
3297 by normal_stop, for the few commands that need it, speeding up
3298 serial I/O. Add comments to stop_registers.
3300 * remote-eb.c: Remove newline from breakpoint message we grep
3301 for. Never time out when running the user program.
3305 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3307 Roll in changes from vxgdb-5.0.1:
3309 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3310 symbol in its raw form, we are processing an unlinked ".o" file.
3311 See if the target environment has assigned it an address, using
3312 target_lookup_symbol (VxWorks does), and enter it into the symtab
3315 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3316 68k versions for a simpler version that assumes zero FP at bottom.
3317 Fixes bug of truncated stack reports.
3319 * target.h (target_lookup_symbol): Define this routine's args
3320 and result, finally.
3322 * target.c (nosymbol): Default routine for target_lookup_symbol.
3323 (target_default): Default lookup_symbol and call_function too.
3324 (files_info): Only print has_all_memory warning if a non-dummy
3327 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3328 vx_convert_from_virtual): If target does not have floating point,
3329 zero register "values", and avoid doing cross-net conversions.
3330 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3331 (vx_open): Rearrange code that attaches to target and reads
3332 symbols for all loaded modules, to work if some of the modules
3333 are not accessible. Add symbol_stub() and add_symbol_stub()
3334 as callbacks from catch_errors(). Allow connect attempt to be
3335 interrupted painlessly with ^C (FIXME, there are still some bugs
3336 if the interrupt happens during symbol reading.). Print
3337 final message with puts_filtered, since symbol messages are
3342 * main.c (catch_errors): Only print errstring if non-null.
3343 (command_loop): Avoid an ioctl per command to test ISATTY.
3345 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3346 (vx_xfer_memory): Return correct result!
3347 (vx_files_info): Indicate whether target has float or not.
3348 (vx_lookup_symbol): Complain, not error, if target gone.
3349 (vx_open): Print "Connected" msg before disabling immediate-quit.
3350 [FIXME: lookup_symbol and vx_open changes need testing.]
3352 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3353 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3354 contributor lines and update copyrights to 1991.
3356 Changes from an attempted H-PUX host port:
3358 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3359 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3360 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3361 * remote-vx.c: include <sys/time.h> for HPUX.
3362 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3363 "core_file_command" routine to BFD regime. May not work yet.
3365 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3367 * xgdb.c: Replace X10 version with some VJ version.
3368 (FIXME: Its copyright assignment is not on record.)
3369 * xgdb.c: Update include files to X11R4 (Xaw crud).
3370 (xgdb_display_source, create_text_widget): fix call to
3371 get_filename_and_charpos. Rewack source window stuff for X11R4
3372 (gleaned from include files, and "nm's" of binary libraries, since
3373 I had no doc available).
3374 (append_selection, append_selection_word): Disable with FIXME
3375 since R4 changed interface here.
3376 (create_buttons): Add back the old set of buttons.
3377 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3379 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3380 Roll VERSION to 3.94 (not yet final though).
3382 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3384 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3385 obstack_int_grow, obstack_int_grow_fast): Eliminate
3386 cast on left of assignment, which gives MIPS cc fits and is
3389 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3390 F_ALIAS. Use printf, not fprintf, when not passing a file
3392 (compare_opcodes): Check that identical instructions have
3393 identical opcodes, complain otherwise.
3395 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3396 was reported by Roland McGrath.
3397 (unimp): Only match if exactly zero instruction. (Roland)
3398 (branches and traps): Generate all variations of these
3399 instructions with macros, based on a single call that defines
3400 each condition name and its binary representation.
3401 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3403 * valprint.c (val_print_fields): Take, and use, format parameter.
3404 This means that "p/x struct" again prints the elements in the
3405 desired format. Changed callers.
3407 * stack.c (frame_info): Use filtered output, and indicate wrap
3408 points. Remove kludgy formatting designed to avoid line wrap.
3410 * utils.c (wrap_here): If the line is already full (because
3411 we had printed a long indent or long wrapped string), do an
3412 immediate newline-and-indent.
3414 * m68k-pinsn.c (print_insn_arg): Bugfix from
3415 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3416 instruction is incorrectly disassembled as bkpt #8.
3418 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3419 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3420 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3421 and then will dump core (sometimes). I traced it back to an
3422 uninitialized symfile_name in psymtab_to_symtab.
3423 (const_vol_complaint): Add quotes to message.
3424 (define_symbol): Only believe line number if gcc_compiled.
3425 Avoid allocating symbol if we will not return it.
3427 Add target strata support so that newly established targets go
3428 into their right place in the target stack (e.g. a new exec file
3429 doesn't wipe out the ability to access the running process).
3431 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3432 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3433 and initialize it properly in all the targets.
3435 * target.h: Document strata. Change return type of push_target.
3437 * target.c (nomemory): new function for dummy memory access.
3438 (tcomplain): Rename complain, now also used in symfile.c.
3439 (push_target): Push targets within strata. New return value shows
3440 whether new target is on top of stack or not. Always keep dummy
3442 (target_files_info): Ignore dummy target.
3444 * core.c (core_open): Warn user, and skip accessing file, if the
3445 core target is not the topmost target in the stack.
3446 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3449 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3450 target_ops, it doesn't belong there since we have no regs there.
3451 Change name of target from machine => memory to clarify.
3453 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3455 * Freeze version 3.93 for release.
3457 * Makefile.dist: Handle vx-share and nindy-share subdirs
3458 properly when building gdb.tar.Z.
3460 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3461 printed in various places, so I could change just one copy.
3463 * dbxread.c, coffread.c: Change references to bfd->iostream
3464 to cast to FILE *, now that BFD avoids needing types defined
3465 in other header files.
3467 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3469 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3470 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3471 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3472 (actually gcc -Wall).
3474 * dbxread.c: Remove first_global_sym, last_global_sym, since
3475 they are never referenced.
3477 * defs.h (baud_rate): Declare.
3478 main.c: Define it, and add the -b option to set it.
3480 * gdb-int.texinfo: Add text on how to define a new host or target
3481 architecture, prompted by Per Bothner's questions about MIPS
3484 * gdb.texinfo: Document "complaints". Change doc of -q since
3485 gdb no longer prints the copyright and blurb if you specify a file
3486 name to be debugged (just like Emacs). Add doc for Nindy-specific
3487 command line flags for specifying target serial port and such.
3488 Update copyright to 1991.
3490 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3491 has taken over for us the job of ripping up executable files. The
3492 crud caused Per Bothner's port to not compile.
3494 * infrun.c (normal_stop): Avoid printing "Program exited
3495 normally" if we are in batch mode. This allows a GDB which
3496 executes a program on a target system, to behave like a Unix
3497 command (input from stdin, output to stdout, no extraneous
3500 * main.c (main): Allow additional machine-dependent command line
3501 options to be specified with the ADDITIONAL_OPTIONS,
3502 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3503 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3504 processing to occur just before the main loop with
3505 BEFORE_MAIN_LOOP_HOOK.
3506 (main): If a "core file" argument is specified, and it is not a
3507 core file, try it as a process ID to attach.
3508 (symbol_completion_function): Attempt to cope with
3509 "show screen-" TAB, not very successfully. This needs more work,
3511 (batch_file): New function, returns whether we are reading
3512 commands from an interactive tty on stdin, or from somewhere else.
3513 Called by normal_stop since it doesn't get from_tty passed down
3514 to it like many commands do.
3516 * remote-nindy.c: Handle command line options for nindy
3518 (nindy_before_main_loop): Prompt user for tty name if they
3519 don't specify it before getting to the interactive command loop.
3521 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3522 and -r command line options. Also add hook before main loop
3523 to make it easy to specify a tty.
3525 * TODO: More things to do, one done.
3527 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3529 * dbxread.c: Make complaint() calls pass pointer, not struct.
3530 Add complaints about badly formatted C++ type information
3531 (const/volatile indicator, and parse errors resulting in
3532 error_type). Fix C++ virtual member fn comment.
3533 (read_struct_type): Avoid bumping pointer if we got a parse
3534 error; this prevents our walking beyond the end of a string.
3535 Terminate loop on null char as well as semicolon.
3536 (process_one_symbol): Fix the LBRAC fix so that it uses the
3537 last previous SLINE, FUN, or SO record's PC address. C++ debug
3538 symbols did not have SLINE records in a useful order compared
3539 to the LBRAC records.
3540 (define_symbol): Handle "catch" records.
3542 * symtab.c (check_stub_type): Added new complain
3543 `stub_noname_complain' and added a consistency check to
3544 keep the debugger from crashing when finishing from an
3545 exception frame. A real fix will be needed later.
3547 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3549 * infcmd.c (attach_command): Make global.
3551 * Makefile.dist (REMOTE_OBS): Make these compile by default,
3552 but make them easy to comment out. Perhaps later they should
3553 be enabled by what CPU you configure for? FIXME.
3554 (VERSION): Roll to 3.93.
3555 (pinsn.o): Remove rule for obsolete file.
3556 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
3558 Run down a problem that manifested by printing the wrong function
3559 name in stack traces of read_ofile_symtab. Turned out that the
3560 problem was the SunOS 4.1.1 (and previous) C compiler outputs
3561 the LBRAC symbol with an address in the *data* segment, which
3562 blew our binary search through the blocks.
3564 * dbxread.c: Use the complain() facility consistently to bitch
3565 about problems in the symbol file we are reading.
3566 (finish_block): Add code to check the nesting of the blocks;
3567 complain and Procrust them to fit if wrong.
3568 (make_blockvector): Check the order of the blocks, complain
3569 [but don't cope] if wrong.
3570 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
3571 symbols to be sure their PC value is greater than the last SLINE
3572 (line number) symbol we've seen, complaining and adopting the
3573 SLINE PC value if wrong.
3575 * symfile.h (struct complaint, complaint_root, complain,
3576 clear_complaints): Add.
3577 * symfile.c (complain, complaint_root, clear_complaints): Add
3578 facility to deal with non-fatal complaints and to regularize their
3580 (symbol_file_add): Clear complaint counters to allow new complaints.
3581 (initialize_symfile): Add 'set complaints' and 'show complaints'.
3583 * dbxread.c (dbx_symfile_read): Remember the address and size
3584 of the string table for the main symbol file, so we won't read it
3586 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
3587 to avoid reading the string table yet again. Lint.
3588 (throughout): Improve filtered output, including word wrap.
3589 (read_range_type): Improve Bothner's fix to handle other types too.
3591 * utils.c: Improve line wrap implementation. Handle unlimited
3592 width by making chars_per_line unsigned.
3593 (puts_filtered): New, easy, function.
3595 * defs.h (puts_filtered): add.
3597 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
3598 call the identical sort_symtab_syms() in symfile.c instead.
3600 * expread.y: Suggest the `file' command rather than `symbol-file'.
3602 * command.h (enum var_types): Add zinteger for seroable
3604 * command.c (do_setshow_command): Handle var_zinteger. Restructure
3605 nested if's into a switch.
3607 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
3608 we did not stop because of a breakpoint (it must have been for
3609 some other reason, like a "stepi"), so don't print anything.
3611 * symtab.c: Include <sys/types.h> all the time. Now that BFD
3612 doesn't include <sys/types.h>, old SunOS's require it for
3615 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
3617 A test port of gdb-3.92.6 to the Sony NEWS.
3620 Don't normally link in remote- or vx stuff.
3621 Some of it doesn't compile, and it wastes space for 99% of the users.
3622 Remove reference to no-longer-used HAVE_VPRINTF.
3623 Fixed BFD_DEP typo to BFD_DIR.
3625 Fix cast in arg to bfd_h_getlong.
3626 Make char *prefix be const.
3627 Fix how certain range types are mapped into builtin unsigned int types.
3629 Remove 2 #includes. They cause errors (on Sony, at least),
3630 and aren't needed (they wern't in earlier versions).
3632 print_address_symbolic should never demangle labels
3633 (since it prints *assembler-level* labels).
3635 [This was superseded by the change to printcmd below.]
3638 Add some "volatile" return types to avoid warnings.
3639 If MISSING_VPRINTF add vprintf function and not just macro
3640 (since vprintf is used in printcmd.c).
3642 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
3643 (The latter isn't grokked by some PCC-based compilers.)
3645 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
3647 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
3648 * nindy-share/coffstrip.c
3649 Added some forward declarations (otherwise, gcc complains
3650 about implicit extern redefined as static).
3652 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3654 Changes inspired by Per Bothner:
3655 * printcmd.c (print_address_symbolic): Take additional parameter
3656 specifying whether to demangle.
3657 (print_address): Pass in asm_demangle to control demangling.
3658 (print_address_demangle): New fn, takes explicit arg to control
3660 * utils.c: Add new vars demangle and asm_demangle, and let them
3662 (fputs_demangled): If !demangle, just print the argument.
3663 (fprint_symbol): If !demangle, just print raw symbol.
3664 * valprint.c (val_print): Call print_address_demangle rather than
3665 print_address, to cause demangling to depend on the global
3666 rather than assembler-level demangling setting.
3667 * WHATS.NEW, gdb.texinfo: Document.
3669 * main.c (show_command): Show all settings if no arg.
3670 (initialize_main): Make "info set" the same as naked "show".
3671 * command.c (cmd_show_list): Handle prefix commands in the
3672 list, and print the name of the setting as well as its English
3673 description and value.
3675 Allow gdb functions to specify where a line should wrap if it
3676 exceeds the size of a terminal line. Use it to make the output
3678 * utils.c (set_screen_width_command): New fn, mallocs a buffer
3679 of the right size when screen width changes.
3680 (set_screensize_command, screensize_info): Remove #if 0'd fns.
3681 (wrap_here): New fn, indicates a point in the output where we
3682 should wrap the line rather than just letting it overflow at a
3684 (fputs_filtered): Implement wrapping.
3685 (n_spaces): New fn, returns a pointer to N spaces.
3686 (print_spaces_filtered): Use n_spaces.
3687 * defs.h (n_spaces): Declare.
3688 * stack.c (print_frame_info): Wrap with 4-space indent after
3689 fn name and before filename and line number.
3690 * printcmd.c (print_frame_args): Wrap with 4-space indent
3691 before each argument name is printed.
3692 * valprint.c (value_print): Wrap with no indentation before
3694 (val_print_fields): Wrap with indentation relative to nesting
3695 level before each field name.
3696 (val_print): Wrap with nesting indentation before array elements.
3697 * command.c (do_setshow_command): Avoid extra newlines,
3698 wrap with 4-space indent around values printed, end with period.
3699 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
3701 * breakpoint.c (breakpoint_1): Implement addressprint for
3702 "info breakpoints" display. Change file name and line number
3703 format to " at file:nnn" rather than " (file line nnn)".
3704 * gdb.texinfo: Document.
3707 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3709 Frozen for gdb-3.92.6 release.
3711 README, WHATS.NEW: Update for 3.92.6 release.
3713 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
3714 coffread.o from configs since it is now built by default.
3715 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
3716 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
3717 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
3718 from configs since it is now built by default.
3720 Makefile.dist: Update for release 3.92.6. Handle files that
3721 have been moved to ../include, ../getopt, or ../bfd. Add
3722 saber.suppress and tests directory. Add config.status to
3723 the release (it will say "none").
3725 coredep.c: Minor formatting fixes.
3727 These changes were made in early December but only checked in now:
3728 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
3729 nindy-share/nindy.c: lint
3730 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
3731 register values coming back from the target; we store values
3732 in target byte order everywhere.
3734 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
3736 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
3738 * valprint.c (cplus_val_print, val_print_fields): New functions,
3739 which print C++ objects. They conspire to avoid printing a
3740 virtual base class more than once, following all the twists and
3741 turns of C++ virtual base rules.
3742 (val_print): Call the above rather than do it by hand.
3744 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
3745 symbol file, not for added files like shared libs. This really
3746 needs to be generalized to a timestamp per file.
3748 * core.c (cleanup_core): Avoid coredump if no core file.
3750 * config.gdb: Accept -host or -target in place of +host or
3753 * coffread.c (find_linenos): Avoid desupported BFD interface
3754 to line numbers. We still read them manually rather than using
3755 BFD's "generic" features.
3757 * gdbrc.tex, threecol.tex: Add GDB reference card and its
3759 Makefile.dist: Add refcard to OTHERS list for creating tar files.
3761 * Makefile.dist: Eliminate use of $< in explicit targets.
3763 * readline/Makefile: Use $< rather than $*.c, which does not
3764 include the VPATH in GNU Make.
3766 * tconfig/i960-bout, tconfig/i960-coff: These are identical
3767 copies of tconfig/i960, added for global configuration
3768 compatability. All i960 versions can read both coff and b.out.
3770 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
3771 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
3774 * TODO: Think of more things to do.
3776 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
3778 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
3779 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
3780 64-bit float conversion.
3782 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
3783 equivalent to sun?os4 so global config works.
3785 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
3787 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
3789 * main.c: Only declare linesize once; declare pagesize not at
3790 all, since it is never used.
3791 (main): Clear newly allocated line before it is used.
3793 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
3795 Further stabilization for the Intel 960.
3797 * Makefile.dist: Parameterize the location of the "include"
3798 and "bfd" directories, as well as "getopt". Add symfile.c.
3799 Link in both dbxread and coffread. Fix up "make depend" to
3800 rewack the locations of include, bfd, and getopt in its output.
3802 * README: Document moving include files, improve some of
3805 * coffread.c: Move common code out to symfile.c. Change
3806 symbol_file_command style interface to use new *_symfile_init
3807 and *_symfile_read interface under BFD. Use BFD internal
3808 info to locate line table, symbols, etc.
3810 * core.c (core_fetch_registers): Rename to get_core_registers
3811 to avoid confusion with fetch_core_registers.
3812 (register_addr): Move to coredep.c, which is already machine
3813 dependent. This leaves core.c pretty clean of dependencies.
3815 * coredep.c (register_addr): Accept this routine from core.c.
3817 * dbxread.c: Move common code (with coffread.c, etc) into new
3818 symfile.c. Each psymtab now contains a pointer to the
3819 format-dependent function that knows how to read it in. Make
3821 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
3822 (process_one_symbol): Add code to complain about a "compiler bug
3823 we muzzle here", if we actually see it.
3825 * eval.c (evaluate_subexp): Insert missing "break" statements
3826 in code that determines whether a variable is an lvalue in
3827 memory, register, or whatever. I detected this via a compiler
3828 bug in which it *almost* mashed out the whole switch statement.
3830 * gdb-int.texinfo: Add minor sections on configuring gdb for
3831 release, and about the README file.
3833 * infcmd.c (registers_info): Fix formatting somewhat. Still
3834 not as pretty as before, but it handles byte swapping.
3836 * remote-nindy.c: If data cache routines are interrupted while
3837 waiting for the remote end, be sure that any uninitialized cache
3838 blocks are on the free list, not on the valid list!
3840 * symfile.h: Flesh out this header file with all the various
3841 routines and variables that have been merged in from dbxread.c
3842 coffread.c, and symtab.c to symfile.c.
3844 * symfile.c: New file, containing code common to dbxread.c,
3845 coffread.c, and some code from symtab.c. All generic code for
3846 reading symbol files should be in here now.
3847 (unrecord_misc_function): Remove unused function.
3849 * symtab.h: Remove file-reading things to symfile.h.
3851 * symtab.c: Remove file-reading things to symfile.c.
3853 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
3854 to decode i960 fault types.
3856 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
3857 target.c: Change type of the "resume" function from int to void,
3858 since its result was never used.
3860 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
3862 * main.c: Replace "stupid" with "caution"; you now "set caution
3865 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
3867 * infcmd.c (do_registers_info): Call val_print to deal with the
3868 byte order of the registers being printed. FIXME, this makes
3869 the formatting of the output uglier.
3871 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
3872 defined, call it for signals the debugger doesn't itself use.
3873 The i960 uses this for more detailed fault information.
3875 * remote.c (remote_open): If arg is null, print help rather than
3878 * sparc-xdep.c (register_valid): Avoid declaring size, since
3879 various modules will think of various sizes depending on the
3880 architecture of their tm-file. FIXME, we need protection against
3881 actually entering one of those modules, which would clobber
3882 storage if not for the target architecture compiled into gdb.
3884 * stack.c (up_command, down_command): Always print the frame
3886 (up_silently_command, down_silently_command): New commands
3889 * i960-pinsn.c (reg), i960-tdep.c: Lint.
3891 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
3892 more parameters than it used to.
3894 * findvar.c (registers): Increase slop to 256 bytes, which should
3895 protect us against even most RISC machines with large register
3897 (locate_var_value): Move declaration inside related ifdef.
3899 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
3900 throughout, to avoid throwing away buffered input from the board.
3901 (nindy_wait): Supply_register takes addr_of_value, not value.
3902 (i960_print_fault): Renamed from i80960_fault.
3903 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
3904 (nindy_store_registers): Avoid regs_changed stuff, just stuff
3906 (nindy_create_inferior): Don't bother to write PC_REGNUM since
3907 we can set the PC in the call to proceed(). Unpush nindy_ops
3908 before pushing it on top, to avoid message to user. Eliminate
3909 commentary from Unix machines that just misleads here.
3910 (reset_command): Fix error message to suggest target command.
3912 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
3914 Release 3.92.5 as frozen.
3916 Stabilize the merged release...with help from lint, Saber C,
3919 Everywhere: Add include files needed to declare return types
3920 of functions called.
3922 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
3924 * breakpoint.h: Add undeclared breakpoint functions, and some
3925 functions for display handling since I couldn't think of a better
3928 * breakpoint.c (insert_breakpoints): Make code for disabling
3929 shared library bkpts more likely to work. It's used when we
3930 rerun a program and stop before the shared library has been
3932 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
3933 cast from pointer, so it squeezes through catch_errors.
3934 (bpstat_stop_status): Fix logic broken some time ago. We now
3935 always create a bpstat if the stop address matches a breakpoint,
3936 even if we don't stop there -- just like the old code used to do
3937 before I got my fingers into it (sigh).
3938 (breakpoint_1): Print "ignore count" after "stop only if"
3939 condition, since that's how it actually works.
3940 (mention): Handle watchpoints as well as breakpoints.
3941 (watch_command): use set_raw_breakpoint and mention to do most
3942 of the work (and initialize all the fields!). Only pass one
3943 arg to parse_c_expression, since that's all it takes.
3945 * command.c (not_just_help_class_command): Rename arg to args
3946 since we ignore "unused argument" warnings on vars named "args".
3947 inflow.c (child_terminal_info): ditto.
3948 infptrace.c (kill_inferior): ditto
3949 main.c (catch_errors, version_info, quit_command, pwd_command,
3950 source_command, dump_me_command, editing_info,
3951 set_history_size_command, set_history, show_history,
3953 stack.c (locals_info): ditto
3954 target.c (target_files_info): ditto
3955 valprint.c (set_input_radix, set_output_radix): ditto
3957 * core.c: Remove old variables for handling core and exec file
3958 sections (data_start, data_end, stack_start, stack_end,
3959 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
3960 text_end, exec_data_start, exec_data_end, text_offset,
3961 exec_data_offset, data_offset, stack_offset). They're
3962 superseded the more general build_section_table and
3964 (get_exec_file): Mention the `file' command.
3965 (read_memory_check): Rename to memory_error, and only call it
3966 in the case of an actual error.
3967 (read_memory, write_memory): call memory_error.
3968 (core_fetch_registers): Register section name is ".reg".
3970 coredep.c: Remove a bunch of crud now that all this file does
3971 is pull the registers out of a core file.
3972 (fetch_core_registers): Rewrite to actually work, I hope.
3974 dbxread.c: Use a.out.gnu.h, not system a.out, now.
3975 Replace index() with strchr(). Remove all the pre-BFD macro
3976 definitions for accessing the symbol file.
3977 (struct dbx_symfile_info): Encapsulate the information that
3978 dbx_symfile_init needs to pass to dbx_symfile_read in this
3981 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
3982 dbx_symfile_discard): Rearrange symbol file reading to divide
3983 the format-specific part from the format-independent part,
3984 leaving the format-independent part such as file name expansion
3985 and opening in symtab.c. This replaces
3986 partial_symbol_file_open and partial_symbol_file_read.
3987 Symbol_file_read, add_file, add_file_target_command,
3988 add_file_addr_command move to symtab.c. Pass an explicit
3989 "mainline" flag for when reading the main symbol table, rather
3990 than relying on the offset address to be zero or nonzero.
3992 (dbx_symfile_read): Don't allow void *'s to be printed as
3994 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
3995 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
3996 macro" debug version really work.
3997 (read_dbx_symtab): Remove unref'd parameter inclink.
3998 Avoid swapping N_SLINE symbols, for speed.
3999 Merge N_TEXT!N_EXT case with the other external symbol
4000 definitions' case. Add comments.
4001 (start_psymtab): Allocate the symfile name in the psymtab on
4002 the psymbol_obstack, rather than using the caller's storage.
4003 (end_psymtab): Only allocate a dependencies list if there are
4005 (psymtab_to_symtab_2): Use BFD when reopening file to read
4006 its symbols for real.
4007 (read_struct_type): Add FIXME comments where it needs work
4009 (read_huge_number): Add FIXME about overflows.
4010 (read_range_type): Add FIXME about comparing a long to 1<<32.
4012 * coffread.c: Minor changes to move things closer to the new
4013 regime with symtab.c and dbxread.c Major work is still needed
4016 * exec.c (exec_file_command): Remove old variables (see core.c
4018 (xfer_memory): If memory transfer is right at the end of a
4019 section, don't lose.
4021 * findvar.c (get_saved_register): If value is in a real
4022 register, LVAL is lval_register, not lval_memory.
4024 frame.h: Declare print_sel_frame and record_selected_frame.
4026 gdb-int.texinfo: New file, for GDB internals documentation.
4027 Very simple, unformatted doc of cleanups is there for now.
4029 gdbcore.h: Remove obsolete variables that described a.out
4030 section addresses and offsets. (See core.c above.)
4031 Declare fetch_core_registers and registers_fetched.
4033 getopt.c: Declare char *alloca(); even on SPARC.
4035 infcmd.c (run_command): Call target_kill rather than
4037 (step_command, next_command, stepi_command, nexti_command):
4038 Declare from_tty parameter even though we don't use it.
4039 (run_stack_dummy): argument BUFFER is a char array, not
4040 a pointer to REGISTER_TYPE.
4041 (finish_command): using_struct_return needed a value *,
4042 not a struct symbol *.
4044 * infptrace.c (child_xfer_memory): To avoid dependency on
4045 where sections are in memory, try PT_WRITE_D and if that fails,
4046 try PT_WRITE_I. Most Unixes don't care which you use.
4048 * infrun.c (step_resume_break_shadow): Change to array to
4049 match other breakpoint shadow storage.
4050 (clear_proceed_status): Pass address of bpstat to
4051 bpstat_clear, not the bpstat itself.
4052 (child_create_inferior): FIXME comment about if the child
4054 (start_inferior): Remove old function.
4055 (child_open): Use target_kill rather than kill_inferior.
4056 (wait_for_inferior): Ditto.
4057 (insert_step_breakpoint, remote_step_breakpoint): Use
4058 new step_resume_break_shadow.
4060 * inftarg.c (child_wait): If all child processes die,
4061 pretend that the one being waited for exited with signal 42.
4063 * main.c (command_line_input): When scanning for comments,
4064 don't coredump on unclosed quotes.
4065 (quit_command): Use target_kill rther than kill_inferior.
4066 (_initialize_main): Rename class_user from "user" to
4069 * printcmd.c (print_command_1): Initialize "fmt" if no format
4070 is specified by the user.
4071 (print_frame_args): Only add to args_printed if we are
4072 actually fetching args from the stack (avoiding undefined
4074 (_initialize_printcmd): Remove bogus \{ from string.
4076 * remote-eb.c (eb_open): Avoid coredump on no argument.
4078 * remote-nindy.c: Bring out of Intel environment into new
4079 target environment. Remove all conditional compilation on
4080 I80960. Massive hacking throughout.
4081 (nindy_xfer_inferior_memory): New routine stolen from
4083 (nindy_create_inferior): New routine pieced together, probably
4084 not quite working yet.
4085 (nindy_ops): New target_ops struct for nindy.
4087 * remote-vx.c: Use write_memory rather than target_write_memory
4088 to get error checking.
4089 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4091 (vx_create_inferior): Use target_terminal_ours...
4093 * signame.c (_initialize_signame): Always initialize, since
4094 we need the table for things other than psignal.
4096 * solib.c (solib_add): Use symbol_file_add, not add_file.
4097 (solib_address): Return boolean result rather than struct
4098 pointer which nobody else knows the type of.
4100 * sparc-tdep.c, valops.c: Use write_memory rather than
4101 target_write_memory, to get error checking.
4103 * stack.c (locals_info, catch_info, args_info,
4104 get_selected_block, frame_command, up_command): Use
4105 target_has_stack, rather than have_inferior_p or
4108 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4110 * symfile.h: New file, defining the interface between the
4111 generic and object-file-specific symbol reading code.
4113 * symtab.c: Move generic symbol-reading interface to symtab.c,
4114 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4115 table to map BFD targets to symbol-reading modules in GDB.
4116 Change index to strchr.
4117 (lookup_struct_elt_type): Use error() rather than hand-made
4118 simulations thereof.
4119 (lookup_partial_symbol): Speedup slightly when length == 0.
4120 (symbol_file_add): New function.
4121 (symbol_file_command): Call it.
4122 (symfile_open, symfile_init): New function.
4123 (add_file_target_command, add_file_addr_command): moved from
4126 * target.c (target_command): use target_kill.
4128 * target.h (target_files_info): Don't declare, never called
4131 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4132 files to determine stack end address.
4134 * valarith.c (value_x_binop, value_x_unop): Change error message
4135 to be more useful. Pass proper argument to value_struct_elt.
4137 * valops.c (value_assign): FIXME comment that long long
4138 bitfields will break here.
4140 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4141 Update `make saber_gdb' to work better.
4143 * TODO: A woman's work is never done.
4145 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4146 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4147 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4148 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4149 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4150 valops.c, valprint.c, exec.c: Lint.
4153 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4155 Continuing Intel 960 port merge of GDB.
4157 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4158 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4159 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4160 Wack over "make depend" so it handles files in subdirectories
4161 vx-share, nindy-share, bfd, and in the current directory.
4163 * blockframe.c (get_prev_frame_info): Remove fatal error
4164 if stack not defined.
4166 * core.c (core_open, core_detach): New functions that handle
4167 the old "core-file" command as "target core" and "detach" instead.
4168 (core_file_command): Call them.
4169 (core_xfer_memory): Use common routine xfer_memory.
4171 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4172 dbxread now uses bfd for everything but symbol reading itself.
4173 BFD internals are used to drag out the relevant file offsets.
4174 (partial_symbol_file_open): Change args all around for BFD.
4176 * symtab.c: Rename "value" to "val" everywhere, so we can
4178 (symbol_file_command): New command, moved from dbxread.c
4179 and coffread.c. It uses BFD to read the file, then vectors
4180 based on its type, to dbx or coff symbol readers.
4181 * symtab.h: Extern a few vars for symbol_file_command.
4183 * target.h: Breakpoint takes a char * save area, not a char **.
4185 * valprint.c (val_print): When unpacking bitfields, offset
4186 the address in gdb of the value, if it is declared with a shorter
4187 type. Remove the last "runtime kludge test" of host byte order.
4189 * utils.c: Remove old my_bfd_read routine.
4191 * stack.c (frame_info): Use target_has_stack. Print program counter
4192 register's actual name rather than "pc", since it's called the
4193 "ip" (instruction pointer) on the i960 (sigh).
4195 * target.c (target_command): Add command for selecting a target
4196 type and calling its open routine. This is used for initiating
4197 communication with a particular target, in a generic way.
4199 * tm-i960.h: Update for modern gdb. Remove semicolons from
4200 various macros. Handle reading struct return convention, and
4201 error-out attempts to return structs with the "return" command.
4202 Be sure gdb doesn't think we know how to call functions in the
4205 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4206 to i960_xxx in lower case.
4207 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4208 not being defined yet.
4210 * remote.c (remote_open): Call start_remote to initialize
4211 wait_for_inferior during open.
4212 (remote_xfer_inferior_memory): Return length written rather
4215 * remote-vx.c (target_command -> vx_open): Use new generic
4217 * remote-eb.c, inftarg.c, exec.c: ditto.
4219 * infrun.c: Fix comments.
4220 (attach_program -> child_open): Use new generic target command.
4221 (wait_for_inferior): Clear saved register values before target_wait,
4222 so target_wait can set some of them if convenient.
4224 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4225 Return success indicator, not void.
4226 (child_xfer_memory): Avoid fetching initial word if we'll
4227 overwrite it anyway.
4229 * infcmd.c (attach_command): Use new generic target open routine.
4230 (_initialize_infcmd): Update doc on attach and detach commands.
4231 (do_registers_info): Merge in a byte-order problem as a FIXME
4234 * findvar.c (find_saved_register): Avoid problem in current frame.
4235 (read_relative_register): Ditto.
4236 (write_register): Convert byte order on the way out.
4238 * exec.c (file_command): Add.
4239 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4240 (xfer_memory): Common function between core_xfer_memory and
4242 (exec_xfer_memory): Use it.
4244 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4246 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4247 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4248 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4250 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4252 Merge Intel 960 port of gdb, continuing...
4254 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4255 symbol_file_command): Pass from_tty arg to hush 'em up.
4257 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4258 Add magic numbers for 960 COFF format.
4260 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4262 Merge Intel 960 port of gdb, from Intel "1.2" release.
4264 CHANGE_LOG entries from their port, which was based on
4267 Thu Sep 6 11:02:22 PDT 1990
4268 Remove temp file if download is interrupted.
4270 Wed Aug 1 09:08:33 PDT 1990
4271 Now uses binary protocol to talk to NINDY.
4272 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
4273 Times out after 5 seconds when trying to talk to NINDY.
4275 Tue May 29 12:54:49 PDT 1990
4276 Added variable baud rate (-b switch).
4277 Source code reorganization.
4279 Thu Apr 26 11:09:55 PDT 1990
4280 More cleanup of batch mode; specifically, execute "-s", "-e", and
4281 "-se" switches as soon as they are encountered on the invocation line.
4283 Fri Apr 20 13:47:15 PDT 1990
4286 Thu Apr 19 09:54:28 PDT 1990
4287 Add 'reset' command.
4289 Wed Apr 18 09:48:07 PDT 1990
4290 After opening remote tty, wait for 1 second to go by without input
4291 from it before trying to talk to NINDY (fixes problems with the
4292 Heurikon HK80/V960E).
4294 Mon Apr 4 16:33:05 PDT 1990
4295 Some output was not being suppressed in 'batch' mode.
4297 Thu Mar 22 15:31:11 PST 1990
4298 Ask user if old symbol table should be deleted when new file is
4301 Allow user to run a program downloaded before gdb960 was brought up.
4303 Correct "exec-file" help message for i80960 context.
4305 Correct bug in calculating user space address: could occasionally
4306 corrupt user program.
4308 Make sure to zero low-order bits in rip's because of bug in 960CA
4309 A-step part: could cause operation faults when "next"ing across
4312 Correct bug that made it impossible to get source line numbers for
4313 code loaded at addresses higher than 0x7fffffff.
4315 Wed Jan 10 12:43:22 PST 1990
4316 Open remote tty for exclusive use.
4318 Fri Jan 5 12:14:42 PST 1990
4319 Correct disassembly (CA manual was right after all):
4320 opcode for sysctl is 0x659
4322 Mon Oct 23 12:03:04 PDT 1989
4323 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4325 Mon Oct 16 14:15:09 PDT 1989
4326 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4328 Mon Oct 2 15:56:31 PDT 1989
4330 Added 960CA disassembly support.
4332 To simplify maintenance:
4333 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4335 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4336 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4337 - made disassembly interface identical to that in gdmp960.
4341 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4343 * target.h: Allow targets to stack. Add target_has_memory,
4344 _registers, etc. Restructure memory access and "info files"
4345 to walk the target stack.
4346 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4347 target.c: Change tables to match target.h.

4352 * remote-eb.c: New memory regime, new info files.
4353 * remote-vx.c: New memory regime, new info files. Now use
4354 separate targets for VxWorks attachment to machine, and
4355 actually running a process under VxWorks, since one has
4356 stack & execution & regs and the other doesn't.
4357 * remote.c: New memory regime, new info files.
4358 * sparc-xdep.c (fetch_core-registers): New memory regime.
4359 * target.c: New routines and support for stacked targets,
4360 new memory regime, new info files regime.

4364 including use of the new BFD (binary file) library.
4365 * gdbcore.h: Add struct section_table.
4366 * exec.c (build_section_table): Iterate all sections and
4367 record what gdb needs to know about them.

4389 since been deleted, such as temporary breakpoints.
4390 infcmd.c (program_info): ditto.
4392 * core.c (core_file_command): Display the frame where the core
4397 * remote-vx.c (target_command): Merge in target command from

4400 * TODO, Projects: Lots more stuff to do...
4402 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4404 Massive changes to wall off the remote-debugging interface
4405 behind a function vector. The port to handle VxWorks targets
4406 is also part of this.
4408 All files: Replace references to renamed functions,
4409 remove references to remote_debugging, remove references to
4410 have_include_file, have_core_file in favor of target_has_stack,
4411 target_has_memory, etc.
4413 * Modularize the breakpoint interface.
4414 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4415 a breakpoint instruction.
4416 breakpoint.c: struct breakpoint's shadow_contents now sized as
4418 (insert_breakpoints): Vector to target to install breakpoints.
4419 (remove_breakpoints): Vector to target here too.
4420 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4421 sparc-tdep.c (single_step): Use new breakpoint interface for
4422 the single-step breakpoints.
4423 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4424 New file, contains routines to insert and remove breakpoints by
4425 reading out the old contents and later replacing them. This is
4426 how ptrace breakpoints work, and many remote systems as well.
4428 * tm-vxworks68.h: New config file, overrides a few things for
4429 Wind River's preferences.
4431 * target.h: New file, for transfer vector used to talk to the
4432 inferior (child, attached, core, exec, remote, etc). All accesses
4433 to the thing being debugged should come through these vectors.
4434 target.c: New file, routines to handle transfer vector.
4435 (various files): Add transfer vectors XXX_ops for the various
4436 targets and pseudo-targets (core files, etc) we support.
4438 * breakpoint.c (bpstat_stop_status): Further explorations of
4439 watchpoints and why things don't work all the time.
4440 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4442 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4443 the local gdbinit if it doesn't already have it.
4445 * core.c (core_ops): add and install.
4446 Allow core debugging without exec file.
4448 * dbxread.c (free_and_init_header_files): Merge two fns.
4449 (end_symtab): Free named symbol table when a new version comes in.
4450 (read_dbx_symtab): Relocate all kinds of symbols with base
4451 address. First step toward handling different text, data, bss
4453 (add_file_addr_command): Renamed add_file_command.
4454 (add_file_command): Vector to remote handler.
4455 Add "load" as an alias for "add-file" command.
4457 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4458 non-returning functions.
4460 * exec.c: Add exec_ops, and push it as a target when an exec
4463 * infcmd.c (run_command): Pass executable file name and arg list
4464 separately when starting an inferior. Permit "run" when no exec
4465 file is specified, for VxWorks.
4466 (detach_command): Move to child_detach in inftarg.c.
4468 * inftarg.c: New file. Unix-child-specific routines, and the
4469 child_ops structure.
4471 * inferior.h (registers): Export "registers" as the way for
4472 target dependent register handlers to find gdb's local copy of
4473 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4474 since it is now used by places that want wait_for_inferior to
4475 handle the grunge but want to see every trap from the inferior.
4477 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4478 Eliminate remote_debugging hooks in terminal handling.
4480 * infrun.c: Replace start_inferior with child_create_inferior.
4481 Move all the hair of Unix shells and ptrace idiosyncracies into
4482 child_create_inferior, so remote handlers don't have to deal.
4483 Remove running_in_shell. Rename stop_after_attach to
4484 stop_soon_quietly, and use it in a few other places where we want
4485 to just call wait_for_inferior and get control back on the first
4486 trap. trap_expected now never takes a value > 1.
4487 (init_wait_for_inferior): Initialize static vars when a new
4490 main.c (gdbinit): Add new hook for .gdbinit file name, let
4491 it be overridden by config files as GDBINIT_FILENAME.
4492 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4493 Both of these are used for VxWorks gdb.
4495 mcheck.c: rename include file "gmalloc.c" to avoid problems
4496 with system include file "malloc.c".
4498 param-no-tm.h: New include file, same as param.h but does not
4499 include the default "tm.h" file. This is used in files where
4500 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4502 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4504 remote-vx.c: New file, VxWorks remote debugging support. Uses
4505 RPC routines that are shared with the target system, in directory
4508 remote.c: Vectorize remote interface.
4510 source.c: Globalize source_path, and make an alias "l" for "list"
4511 since we now have the "load" command.
4513 sparc-xdep.c: Use new param-no-tm.h.
4515 symmisc.c (free_named_symtab): Add new function from Wind River.
4516 However, ifdef it out for now while we think about what it should
4519 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4521 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4522 non-Unix-children handle this with their own code in the target
4525 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4526 source and target lists. Add vx-share to default list of include
4527 directories. Add new files to src and target lists: mem-break,
4528 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4529 ${srcdir} versions of munch and createtags are used.
4531 * valops.c (find_function_addr): Split out of call_function.
4532 (call_function_by_hand): Rename call_function; this function
4533 calls functions in the target by laboriously patching the target
4534 word-by-word with the right stack, args, regs, etc.
4537 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
4539 Handle AMD 29000 a bit better.
4541 * remote-eb.c (readchar): Mask received char log to make it readable.
4542 (remote_start): Pass arguments down to executing program.
4543 Make startaddr unsigned.
4544 infrun.c (start_inferior): Accept args, pass them to
4546 infcmd.c (run_command): Pass args down to start_inferior.
4548 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
4549 the target object file format.
4550 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
4552 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
4553 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
4555 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
4557 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
4558 * TODO: We did a few things, we have more to do though.

4561 * inflow.c (inferior_died): Clear deferred stores.
4563 * Debug problems with dummy frames and calls to the inferior.
4564 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
4565 * sparc-tdep.c (do_restore_insn): Simplify.
4566 (sparc_frame_find_saved_regs): Simplify and fix what we find.
4567 (sparc_push_dummy_frame): Simplify and fix what we push.
4568 (sparc_pop_frame): Slightly more hair here, deciding whether
4569 we are restoring a saved PC or returning to a return address in %i7.
4570 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
4572 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
4573 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
4574 * obstack.h (chunkfun): ditto.
4575 * defs.h (xmalloc, xrealloc): ditto
4577 * utils.c (quit): Grab the terminal from the child if necessary.
4579 * inflow.c (term_status_command): Rename to term_info, change
4582 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
4583 (is_delayed_branch): Speed up.
4584 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
4585 Still missing some float ops, and needs testing.
4587 * Support for input and output radixes other than base 10
4588 * defs.h (input_radix, output_radix): Declare.
4589 * expread.y (yyparse, parse_number): Handle changes of input
4590 radix, and ambiguous names-or-numbers in radixes >10.
4591 * printcmd.c (print_scalar_formatted): Print formatted hex
4592 numbers in varying column widths.
4593 * valprint.c (val_print): Use output_format to print scalar ints.
4594 (set_input_radix, set_output_radix, set_radix): Create.
4595 (set_output_radix): Set output_format from output_radix.
4596 (_initialize_valprint): add `set radix' but leave the others off.
4598 * main.c (execute_command): Let stupid questions be turned off.
4599 (_initialize_main): Handle "set stupidity", etc.
4601 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
4602 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
4604 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
4606 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
4607 bfd stuff is still screwed up, but with some manual work, it
4610 * breakpoint.c (bpstat_do_actions): Start over if a command
4611 proceeds the inferior, since the inferior will have stopped and
4612 will need to have its new stop-actions taken care of.
4614 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
4615 compiler fits, simplify it.
4617 * gdb.texinfo (directory command): Doc new dir command.
4618 source.c (directory_command): "dir" now puts things on the front
4619 of the path, moves dups up front, and handles multiple names
4620 on the command line, inserting each one in order. It also
4621 blows away cached line and full_filename info.
4623 * stack.c (backtrace_command): Skip "more stack frames follow"
4626 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
4627 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
4628 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
4629 The only odd one was Gould NP1, which had defined vprintf to
4632 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
4633 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
4634 variable, inspect_it.
4635 valprint.c (print_string, val_print): Use the global inspect_it
4636 to indicate whether to print in Epoch style or normal style.
4638 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
4640 * printcmd.c (call_command): add an alias for the "print" command
4641 which runs expressions and doesn't print the result if void.
4642 (print_command_1): implement it.
4644 * command.c: Remove #if 0'd code. Initialize all the fields
4645 in add_cmd (). Rename do_nothing_command to
4646 not_just_help_class_command, and make it externally visible.
4647 command.h: add user_commands to struct.
4648 * main.c (define_command): Don't overload c->function with a char
4649 string as well as a function pointer.
4651 * eval.c (evaluate_subexp): Reinstall tiemann changes to
4652 calling convention of value_struct_elt () that got dropped in
4655 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
4656 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
4658 * tm-sparc.h (POP_FRAME): replace some constants with defines.
4660 * sparc-xdep.c (store_inferior_registers): defer stores to regs
4661 until a good time (e.g. when we are about to run the child),
4662 saving ptrace calls.
4663 * infrun.c (proceed): handle DO_DEFERRED_STORES.
4664 * tm-sparc.h: define DO_DEFERRED_STORES.
4666 * sparc-xdep.c (store_inferior_registers): when storing float
4667 registers, don't store stack regs too. When storing the SP,
4668 however, DO store the stack regs too. This fixes a bug in which
4669 the dummy frame is not recognized when a call_function finishes,
4670 because its frame pointer (in the stack regs) was never
4672 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
4673 even though we don't know how to read them from an inferior.
4674 valops.c (call_function): Comment about storing SP.
4676 * infrun.c (save_inferior_status): Save away the original bpstat
4677 chain so it can be restored later. Install the copied version for
4678 use by whoever saved the status. It will be blow away by
4679 restore_inferior_status, and the original chain restored. This is
4680 important for people who have pointers into the original.
4682 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
4683 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
4684 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
4687 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
4689 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
4690 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
4691 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
4693 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
4695 * Merge Mike Tiemann's multiple inheritance changes from Sun.
4696 Store the baseclasses in a type struct starting from array element
4697 0 rather than from the unusual array element 1.
4699 dbxread.c: the above.
4700 (virtual_context): Add
4701 Read new debug information about which virtual function table
4702 a virtual function is from, and store it in fn_field.fcontext.
4704 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
4705 TYPE_FN_FIELD_STATIC_P.
4707 symtab.c: the above.
4708 valops.c: the above. Handle pointer casts of object *'s.
4709 (search_struct_method): Add.
4710 (value_struct_elt): First arg is now a pointer to a value, and is
4713 valprint.c: the above.
4714 values.c (value_virtual_fn_field): Add type arg. Handle
4715 offsetting to the proper object when calling virtual fns.
4717 (baseclass_addr): Add valuep arg.
4719 * README: Document the current state of BFD config (missing).
4720 * TODO, ChangeLog, Makefile.dist: Roll version.
4721 * WHATS.NEW: Add summary of changes since 3.5.
4723 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
4725 * dbxread.c (read_struct_type): Clear bit vectors whenever
4727 symtab.c (B_CLRALL): define.
4729 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
4730 using == rather than =. Huh... This fixes the dreaded problem
4731 wherein builtin_type_int becomes TYPE_CODE_FLT.
4733 * core.c (info_files): Show the inferior pid.
4735 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
4736 already knows how to look in the source directory.
4738 * Remove psymtab hair from many places. Remove duplicated code
4739 for searching symbol tables. Hide psymtabs from most places.
4740 Make it fast to get from a psymtab to its symtab.
4742 blockframe.c (blockvector_for_pc): Remove psymtab hair.
4743 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4744 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4745 dbxread.c: export psymtab_to_symtab, make it work if called N times.
4746 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
4747 new symtab completely. New psymtabs get symtab pointer
4748 initialized to zero. Remove MI warning printf.
4749 symtab.h: Comments. Add psymtab to symtab pointer.
4750 (PSYMTAB_TO_SYMTAB): New macro.
4751 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
4752 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
4754 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
4756 (print_frame_info): Avoid special-casing symbols that have not yet
4759 * source.c (open_source_file): Quick path if we have already
4760 located the source file by its full name.
4762 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
4763 find_pc_psymtab. When a name is found in the misc function
4764 vector, search the symbol table for its mangled name, not the
4765 name that the user typed.
4767 * bfd.h: Fix missing comment terminators, make #endifs match.
4769 * valarith.c (value_less): Handle unsigned int comparisons.
4770 Add FIXME about pointer compares, which assume host and target
4771 pointers are the same.
4773 * command.c (do_nothing_command): lint
4774 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
4775 fix comments on debug symbol format for visibility. Actually set
4776 visibility of symbols.
4777 main.c (echo_command): lint; use <readline/history.h>.
4778 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
4779 obstack.h (_obstack_blank): Rearrange pointer math to avoid
4780 pointing past end of allocated memory; saber complains.
4781 obstack.h: Declare the external functions that we use.
4782 valarith.h: use <string.h>
4783 solib.c (solib_add): lint.
4785 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
4787 * main.c (initialize_main): Default info_verbose to off, now that
4788 symbol reading is fast.
4789 (quit_command): Avoid clobbering exec_bfd while quitting.
4791 * Initial BFD (binary file diddling library) merger:
4792 coffread.c: Change AOUTHDR to struct exe_hdr.
4794 core.c: initialize initialized data at compile time.
4795 (core_file_command): Move from coredep.c, convert to bfd.
4796 (xfer_core_file): Convert to bfd.
4797 exec.c (exec_file_command): use bfd routines.
4799 mips-tdep.c: Remove exec_file_command and friends.
4802 * coredep.c: (fetch_core_registers) Convert core_file_command to
4803 fetch_core_registers.
4804 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
4806 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
4807 (my_bfd_read): More bogosity, which I don't think we call.
4808 (program_name): Remove this atrocity asap!
4810 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
4813 values.c: allocate_repeat_value was not clearing the
4814 optimized_out field.
4815 (value_static_field): minor stylistic fix (wrong macro was used).
4816 valops.c (value_struct_elt_for_address): didn't work for C++
4819 * signame.c (_initialize_signame): Initialize signal names once.
4821 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
4822 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
4823 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
4825 * remote-eb.c: Support user-settable baud rates on the serial port.
4827 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
4829 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
4831 * tconfig/sun3os4: Remove warning about native assembler,
4832 since it also occurs in the xconfig file.
4834 * findvar.c (registers): Allocate some slop after `registers'
4835 to prevent stray accesses from trashing the next variable.
4837 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
4838 on the sun-3, by changing the #ifdef from `sun3' (which is not
4839 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
4840 vars, which happened to follow `registers' in the executable.
4842 * readline/history.c (history_search): Heed gcc-2's advice
4843 and parenthesize && inside ||).
4845 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
4846 tm-29k.c: Insert FSF copyright headers.
4848 * remote-eb.c: Better comments.
4850 * Makefile.dist: Update to 3.91.6.
4851 * TODO: note PREPARE_TO_STORE problem.
4853 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
4855 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
4857 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
4859 * infrun.c (wait_for_inferior, at end): Don't set up
4860 prev_* if the inferior no longer exists.
4862 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
4863 CANNOT_EXECUTE_STACK.
4864 valops.c (call_function): Use it.
4866 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
4868 * inferior.h (PC_IN_CALL_DUMMY): New macro.
4869 infrun.c (wait_for_inferior, 2 places): Use it.
4871 * values.c (value_being_returned): Only use
4872 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
4874 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
4875 right thing for remote-eb.c.
4877 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
4878 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
4880 * blockframe.c: Put get_frame_saved_regs inside #if !defined
4881 (FRAME_FIND_SAVED_REGS).
4883 * findvar.c ({fetch,store}_registers): Check for
4884 REMOTE_{FETCH_STORE}_REGISTER macro.
4886 * findvar.c (get_saved_register): Add argument lval and
4887 change meaning of argument addr.
4888 findvar.c: Change calls to get_saved_register to reflect
4889 new calling convention.
4890 valops.c (value_assign): Use get_saved_register instead of
4891 find_saved_register.
4893 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4895 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
4896 an (uninitialized) pointer to one. Use "&" when passing it
4899 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4901 * coffread.c (getfilename): Use DGUX x_offset and x_name if
4904 * coffread.c (symbol_file_command): Put semicolon after
4906 Put safe_to_init_tdesc_context in #if defined (TDESC).
4907 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
4908 coffread.c: #include <sys/stat.h>.
4909 (read_coff_symtab): Typo: in_source_files -> in_source_file.
4910 Add missing ')' in check for "lc%" and friends. Remove
4912 Declare read_one_sym() at top of file.
4913 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
4914 MC68WRMAGIC can have the same value without causing a duplicate
4917 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
4919 * Allow a Makefile to be built without building the
4920 tm and xm file links that screw up builds in subdirectories.
4921 This is done with `config.gdb none', then you can do things
4922 like `make gdb.tar.Z'.
4923 * tconfig/none: Config file for no target system
4924 * xconfig/none: Config file for no host system
4925 * config.gdb: If no TM or XM files are called out by the
4926 host or target file, don't make links for them.
4928 * cplus-dem.c: Add documentation.
4930 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
4931 simple error, so the user's gdb doesn't crash due to some object
4932 file problem (e.g. somebody is rebuilding the file out from under
4935 * printcmd.c (print_address_symbolic): demangle the symbol.
4937 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
4938 Motorola copyrights in it. Make "make gdb.tar.Z" work.
4939 (alldeps.mak): sort and uniq all results from this; duplicates
4940 hose gdb.tar.Z link building. Remove RCS files from
4941 tconfig and xconfig. Add config files for sun386. Add
4942 a few odd files to OTHERS and HFILES.
4944 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
4946 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
4947 Roll version number to 3.91.5. Make lint work in bindir.
4949 * README: Document cross-debugging and new file structure.
4951 * blockframe.c: Lint. Include "value.h" to declare read_register.
4952 (find_pc_partial_function): remove duplicate line.
4954 * command.h: Lint. Declare error_no_arg and dont_repeat.
4956 * tm-news.h: Remove inadvertently duplicated stuff.
4958 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
4959 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
4961 * config.gdb: Allow `config.gdb host target' form. Clean
4962 up previous change that printed bogus messages when you just said
4965 * core.c: #include "command.h" for lint.
4968 * main.c: Remove some casts of enums. Lint.
4975 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
4977 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
4978 read it from memory. This will allow us to save ptrace calls
4979 eventually. Changed caller single_step too.
4981 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
4982 that we aren't going to use, saving many ptrace calls, especially
4983 when watchpointing or single stepping. Use some #define's for
4985 (store_inferior_registers): Ditto.
4986 (core_file_command): Use some #define's for constants.
4988 * tm-sparc.h: Add #define's for some register numbers, so we
4989 can eliminate the use of random constants in sparc-xdep.c.
4991 * stack.c (frame_command, print_frame_info, up_command,
4992 down_command) Remove frame_changed, since it
4993 causes a bug and doesn't seem to do anything useful. In some
4994 places it was used as a flag, in others as a stack level (?).
4996 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
4997 default is to use the portable (vprintf) version rather than the
4999 * xm-news.h (MISSING_VPRINTF): Add.
5001 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5003 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5005 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5006 about linking debugged programs -Bstatic in the sun?os4 config
5007 files in tconfig and xconfig subdirectories.
5009 * main.c (main): Remove unreached exit(0) now that we exit
5012 * Create TODO file for online bug list. There are too many
5013 "little" bugs to keep track of on paper.
5015 * Change Projects file to refer to bug-gdb@cygnus.com
5016 rather than kingdon@ai.
5018 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5020 * Makefile.dist (VERSION): 3.91.4 now.
5022 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5023 (condense_misc_bunches): Add sanity check that misc_count is
5024 the same as the number of symbols in the bunch.
5026 * coffread.c: rename init_misc_bunches. Pass an argument
5027 to condense_misc_bunches (a zero).
5029 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5030 every time we are called; don't rely on our caller to do it.
5031 (add_file): Remove call to init_misc_bunches.
5033 * mipsread.c: Only warn, don't error, if unknown symbol types.
5034 This keeps an old gdb from falling on its face if it sees newly
5035 extended symbol info. Rename init_misc_bunches.
5037 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5039 * Merge in changes from Per Bothner for DECstations and other
5040 MIPS stuff. The rest is Bothner speaking:
5042 The next message is a merger of Alessando Forin's mips port with
5043 mine. I've tried to use my good if biased judgment to get
5044 the best of both. It *does* need testing.
5046 Some of the changes are general, *not* mips-specific.
5049 Didn't believe in little-endian bit order.
5050 There are still inconsistencies about whether flags
5051 like BITS_BIG_ENDIAN are integer (#if ...) or
5052 boolean (#ifdef ...). I tried to paper over them.
5054 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5055 Moved some misc_function code that was common to
5056 {dbx,coff,mips}read.c to symtab.c.
5057 In the process, I think I cleaned things up a bit.
5058 At the same time, moved obsavestring and obconcat to symtab.c.
5061 Removed obsolete condense_addl_misc_bunches (use
5062 condense_misc_bunches(1) instead).
5065 Needed to include <sys/dir>, at least on DECstations.
5067 valops.c, mips-tdep.c, tm-mips.h:
5068 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5069 conventions (when STACK_ALIGN is insufficient).
5070 Needed on mips, where doubles need 8-byte alignment,
5071 but ints only need 4.
5074 Removed cruft that was not being used.
5075 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5078 Print $ before register-names (I think that makes things a little
5080 Never print two instructions, even if one delays.
5081 Removed hex-disassemble set_cmd. (This is not mips-specific,
5082 so I think the argument is whether it is generally worthwhile or not.
5083 I'm inclined to think not, given how easy it is to
5084 convert between radixes in gdb.)
5087 This is basically Alessando's code.
5088 It doesn't use obstacks; I changed it to use obstacks
5089 in a few minor places where using malloc causes a
5090 memory leak. (Probably, more places could/should be changed.)
5091 I added record_misc_function where it was missing.
5092 In symbol_file_command and add_file_command, I tried
5093 to make the code consistent with more recent versions.
5094 Minor sylistic changes in parse_procedure.
5095 Make a .gdbinfo. psuedo-symbol point back to the real
5096 procedure symbol (using the isym field).
5099 This is basically from my port, but with a lot of details
5100 and a number of routines merged in from Alessando's version.
5101 I basically used my code "raw" backtrace (use heuristics
5102 from the actual code, rather than symbol table info) - though
5103 the idea is Alessandro's. I feel my code is a little cleaner
5104 here, particularly in being a little more flexible, such as being
5105 able to handle gcc-produced code (which it now can).
5106 It also doesn't do frame caching (which is not useful
5107 more recent gdb versions).
5108 I also used my code for push_/pop_dummy, more or less.
5109 I tried to incorporate AF's code for testing sigtramp
5110 while backtracing; I probably got it wrong.
5111 Added mips_print_register, which tries to scrunch as much
5112 information as possible on a screen...
5113 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5114 under mips-pinsn.c), I don't see anything mips-specific here,
5115 and I don't see it being all that useful anyway.
5118 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5119 Use more register names (rather than hard-cases numbers).
5121 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5123 * Hack up 3.90.11 changes:
5125 * Makefile.dist (depend): parameterize $(GCC).
5126 Add solib.c and solib.o.
5127 (readline): Fix vpath for both absolute or relative SRCDIR.
5129 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5130 Also, let the part I didn't understand at least compile so
5131 I can test the rest. FIXME.
5133 * dbxread.c: Fix thinko using strcmp.
5134 (init_psymbol_list): declare static.
5135 (partial_symbol_file_open): Comment cleanups better, avoid
5136 cleaning up the string table since the caller will do that.
5137 Move the stat for mod time into symbol_file_command, temporarily.
5138 (There should be a mod time for each symbol file, eventually,
5139 to control its rereading. FIXME.)
5141 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5142 SunOS, which gives error for shared libs otherwise. (From
5143 Schaefer, probably FIXME needs work for portability.)
5145 * solib.c: Move #include "param.h" to work.
5146 Lowercase all the Uppercase Letters In the Messages.
5147 (find_solib): Clean up inferior_so_name for debug printouts.
5148 Allow no argument, to mean all shared libraries.
5150 * symmisc.c: include param.h to get CLEAR_SOLIB.
5152 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5154 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5155 to 3.90.11. ChangeLog entries below are from this.
5157 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5161 * Makefile.dist (HFILES): Add tm-sunos.h.
5163 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5167 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5169 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5171 * sparc-opcode.h Added single-operand version of rett.
5173 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5175 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5176 Put parens around gcc_p in expansion.
5178 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5180 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5182 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5184 * Changes for Sun shared libraries:
5185 blockframe.c (find_pc_partial_function): If a non-text symbol
5186 is found, set *address = pc - FUNCTION_START_OFFSET.
5187 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5188 Disable breakpoints instead of giving an error.
5189 source.c (select_source_symtab): Initialize cs_pst.
5190 symmisc.c: Call CLEAR_SOLIB if defined.
5191 symtab.h: Make text{low,high} CORE_ADDR not int.
5192 (psymtab): New field addr.
5194 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5195 (record_misc_function): Give correct type for N_DATA symbols.
5196 (condense_misc_bunches): do "misc_function_count = j" regardless
5198 Take code which is shared between symbol_file_command and
5199 add_file_command and put it into partial_symbol_file_{open,read}.
5200 Split add_file_command into add_file_command and add_file.
5201 Make psymtab_to_symtab read in the string table if the file
5203 Two new parameters to read_dbx_symtab and start_psymtab.
5204 tm-sunos.h: New file.
5206 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5208 * infcmd.c: Change cont_command to continue_command and "cont"
5211 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5213 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5215 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5217 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5218 size 1,2,4,8 rather than size < 8.
5220 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5221 as necessary, not just once.
5223 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5225 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5227 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5229 * tm-news.h: Add CALL_DUMMY_*.
5231 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5233 * config.gdb: In list_host, list_target, use ${i}, not $i.
5235 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5237 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5239 * sparc-opcode.h: Change all store floating-point state register
5240 instructions to have the right match & lose fields.
5242 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5244 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5246 config.gdb: If srcdir != ., create readline directory and
5247 copy a makefile into it.
5249 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5250 consistency with POSIX.
5252 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5253 when we exit its exp_valid_block.
5255 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5257 * Makefile.dist: Bump version to 3.91.3.
5259 * Clean up handling of breakpoint commands (somewhat).
5260 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5262 inferior.h: Add breakpoint_proceeded to inferior status struct
5263 and globals; save it and restore it.
5264 (clear_breakpoint_commands): Cleanup, remove old #define.
5266 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5267 (save_inferior_status, restore_inferior_status): handle it also.
5268 (proceed): Remove earlier code that set breakpoint_proceeded.
5269 It is now set only in clear_proceed_status.
5270 (clear_proceed_status): Cleanup, use bpstat_clear rather
5271 than clear_breakpoint_commands. No callers need the stop_bpstat
5272 between clear_proceed_status and proceed.
5274 infcmd.c: Add breakpoint_proceeded definition and comment.
5275 (cont_command, jump_command, signal_command): Move call to
5276 clear_proceed_status right next to call to proceed.
5278 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5279 caller's argument while running down the chain of breakpoints.
5280 Use new variable "breakpoint_proceeded" to determine when
5281 a command that it executes moves the inferior past the
5283 (bpstat_clear): Handle NULL argument.
5284 (bpstat_clear_actions): Avoid useless call to
5285 breakpoint_auto_delete.
5286 (delete_breakpoint): Clean up bpstat's that are pointing to
5287 the deleted breakpoint from the stop_bpstat chain.
5288 (breakpoint_auto_delete): Simplify.
5290 * Clean up handling of EOF, error on stdin, etc. This was
5291 prompted by a network problem that caused gdb to go into an
5292 infinite loop filling up its malloc'd memory.
5294 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5295 not clear_breakpoints_commands, which is now gone.
5296 (main): If command_loop returns (e.g. from EOF on stdin), do
5297 a quit_command (looping back to command_loop if quit_command
5298 doesn't really quit).
5299 (command_loop): check result from command_line_input and
5300 exit if it returns NULL, rather than passing the NULL to
5302 (gdb_readline): Free malloc'd result space before returning
5305 * utils.c (query): Handle C-d to mean "yes", just as if the
5306 input was not a terminal. Also avoid infinite loop if EOF
5307 occurs in mid-input-line before newline. This allows
5308 query to be used at EOF on stdin with reasonable results.
5310 * infrun.c (proceed): Set breakpoint_proceeded.
5312 * values.c (value_as_long): Avoid infinite recursion for enums.
5313 (_initialize_values): Fix typo in help msg (kingdon).
5315 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5316 RL_LIB for linking. This allows -lreadline for linking
5317 and nothing for dependencies, once readline is a real library.
5319 * config.gdb: Jim Kingdon: give useful error message if the
5320 host or target type is not recognized.
5322 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5323 it just defines it. Dumb, but deal with it.
5325 * Jim Kingdon suggests:
5326 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5328 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5330 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5332 * Clean up Bothner's changes.
5334 * blockframe.c (clear_pc_function_cache): New function.
5335 * blockframe.c: remake cache_pc_function_* static.
5336 * dbxread.c (symbol_file_command): remove references to
5337 cache_pc_function_* variables.
5338 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5339 * printcmd.c: Avoid kludging a global variable (addressprint)
5340 to avoid printing the address of a string twice. Instead,
5341 pass the format letter 's' down low enough that it can be seen
5342 to avoid this problem.
5343 (print_formatted): Pass format arg to value_print.
5344 (restore_addressprint): Remove function.
5345 (do_examine): Avoid hacking addressprint, cleanups and such.
5346 (print_frame_args): Add a comment to a Bothner change.
5347 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5348 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5349 to wipe out the values cached in blockframe.c.
5350 * symtab.c (find_method): Add comment saying how big you must
5351 allocate to be "big enough". Per being terse again.
5352 * valprint.c (val_print): Handle format letter "s" to print
5353 strings without addresses. Add comment to vtbl printing code
5354 which casts with wild abandon. Rearrange reference-printing
5356 @0xaddr: value (print w/addressprint)
5357 value (print w/~addressprint)
5358 @0xaddr (parameter lists w/addressprint)
5359 or nothing (parameter lists w/o addressprint)
5361 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5363 * Merge more changes from Per Bothner:
5365 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5366 annoying) that I tried to improve it. Here are my suggestions.
5368 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5371 Do automatic de-reference when taking the address of a reference.
5373 Don't deref_ref when printing parameter lists.
5375 More attempts at treating refernences properly.
5377 In val_print, if deref_ref==0, don't print dangling " = ".
5379 Add COERCE_REF macro, which de-references an REF.
5381 * Merge changes from Per Bothner:
5383 * Fixed (Sony news)-specific configuration problems.
5384 * Fixed other problems with using vanilla pcc and libc (enum problems;
5385 assumption that vsprintf exists).
5386 * Some major speed-ups (finc_pc_partial_function now caches a match;
5387 parsing avoids duplicate symbol_lookup calls).
5388 * Changed handling of baseclasses (no longer use baseclasses field
5389 of struct type, use the first n_baseclasses fields instead).
5390 * Various minor changes/fixes, most C++-related.
5393 Cache the most previous match from find_pc_partial_function.
5394 (Save both low and high ends of matching function's pc range.)
5395 This speeds up the loop of infrun.c:wait_for_inferior quite
5396 a bit, and makes step/next commands much zippier.
5398 Added an enum->int cast (otherwise, some compilers barf).
5400 No longer set baseclass offset to 0, since multiple
5401 inheritance now mostly works.
5402 Added a number of casts, to shut up compiler warnings
5403 (after stabs where made enums, not ints).
5404 When discarding a symbol table (in symbol_file_command),
5405 must clear the cache introduced in blockframe.c.
5406 Don't convert $vtbl_ptr_type to vtbl any more.
5407 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5408 Mask off sign bit emitted by g++ for virtual table offset.
5409 Set voffset to -1 (not 1) for static member functions.
5411 Changed parsing/lexing of names to avoid doing symbol lookup twice
5412 (once when lexing to determine symbol class, once for real).
5413 Now only call symbol_lookup once. Fields of 'this' win especially big.
5415 Subpress printing addr twice in the case of 'x/s addr'.
5417 lookup_basetype_type is no longer used.
5418 Add find_methods as recursive helper function to decode_line_1.
5419 This allows multiple inheritance to work.
5420 Also, once one or more matches has been found, do not look in
5421 base-classes. (Baseclass methods would be overridden, anyway.)
5423 Removed baseclasses array in struct type.
5424 Instead of using baseclasses[i], use fields[i-1].
5425 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5426 Changed sign convention of voffset (previous was inconsistent).
5428 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5430 Used to assume existence of vsprintf. Re-written to not need it
5431 if HAVE_VPRINTF is undefined.
5433 typecmp was too pessimistic. Made it less so.
5435 Don't print space after address.
5436 If vtable points to a misc symbol (with 0 offset), print it,
5437 since that indicates the actual class of the object.
5438 Changed ype_print_derivation_info to use new inheritance
5439 scheme (without baseclasses vector).
5441 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5442 Also, changes needed because TYPE_BASECLASSES were removed.
5444 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5446 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5449 If there is no path set, and the symbols don't indicate what directory
5450 a file was compiled in, look in the current directory. But either
5451 a path or a known compilation directory will prevent this.
5454 Three independent bug fixes:
5455 * Remove the #if 0 block that breaks some stuff.
5456 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5457 adapt gdb to either SunOS 4.0.* or 4.1.
5458 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.

5475 * Changes merged by John Gilmore:
5478 In breakpoint_1, use new print_address_symbolic instead
5479 of find_pc_partial_function. (This forces use of assembler-level
5480 addresses, and avoids misleading non-mangled source-level names.)
5482 Generalize ansi argument such that -1 means skip arglist totally.
5483 Removed global variable print_ansi_qualifiers (which made
5484 code non-reentrant), in favor of extra explicit arguments
5485 to internal routines.
5487 Add new helper function print_address_symbolic.
5488 Use find_pc_misc_function instead of find_pc_partial_function
5489 (since we want assembler-level symbols here).
5491 Print unknown function as just "f (...)", not "f (...) (...)".
5492 Use new fputs_demangled explicitly.
5494 Fixed a typing violation (problem: value.h cannot be imported
5495 without renaming many variable in this file).
5496 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5497 decode_line_1: Moved forward some never-reached code.
5498 Made decode_line_2 skip function prologues correctly.
5500 fputs_filtered should not demangle by default.
5501 Add new fputs_demangled to demangle on demand..
5503 Change value_struct_elt to use value_primitive_field (using recursive
5504 utility function search_struct_field). This allows foo.bar to work
5505 for multiple inheritance (so far only for data fields).
5506 Change check_field in the same way (recursive helper function
5507 to support multiple inheritance).
5508 (Note: there are more of these problems that I haven't fixed.
5509 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5510 value_of_this: 'this' symbol name is now just "this", note "$this".
5512 Don't print static members.
5513 Avoid printing "members of <type>" if there are none.
5514 Simplified type_print_derivation_info by merging duplicate code.
5515 Remove useless blank lines in type_print_base (ptype command).
5517 Added declaration of new routine value_primitive_field.
5519 Added value_primitive_field which is generalized version of
5520 value_field that can handle multiple inheritance (non-zero offsets etc).
5521 Re-implemented value_field to call value_primitive_field.
5523 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
5525 * infcmd.c -- insert else to avoid 'delete env' coredump when you
5526 delete the whole environment. Karl Berry reported the bug.
5527 * source.c - fix openp to avoid //'s in filenames, which
5528 trigger an Emacs bug causing it to not be able to find files
5529 when running gdb in a window.
5530 * dbxread.c - zap the #if 0 that botches the add-file code.
5531 It seems to work a lot better without all the code commented out.

5541 added remote-sa.sparc.c
5542 * added remote.sa-sparc.c, a modification of remote.c
5543 which conducts a dialog directly with the SparcStation prom.
5544 * breakpoint.c, infrun.c, sparcdep.c added
5545 remote_insert_breakpoint(), and remote_remove_breakpoint()
5546 to breakpoint.c instead of directly writing breakpoint instructions.
5547 * sparcdep.c on remote_debugging,there is no need
5548 to remove signle step breakpoint instructions.
5549 * main.c added "-epoch" flag and "int epoch_interface" to main.c
5551 * printcmd.c - epoch interface sends lisp expressions to open up

5554 format controls easier
5555 * wait.h added a couple of undef's because we were getting
5556 complaints about WSTOPSIG and WTERMSIG begin redefined.
