1 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
3 * dbxread.c: Enable, but soften, const_vol_complaint.
4 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
5 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
6 should be file-scope, not global.
7 (read_struct_type): Remove ancient multiple-inheritance warning.
8 (read_range_type): Check base type, complain & patch if undefined.
9 * stack.c (frame_info): Demangle the function name in `info stack'.
12 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
14 * eval.c (evaluate_subexp_for_address): Don't use
15 TYPE_POINTER_TYPE directly (it might be zero if this type has
16 never had a pointer created before); use lookup_pointer_type.
17 * symtab.c (lookup_method_type): Arguments were swapped in all
18 callers, so fix it here. I'm amazed this worked at all!
20 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
22 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
23 "bss" rather than "data" symbols, but which still conflict.
26 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
27 * core.c (core_files_info): Shorten output.
28 * exec.c (exec_files_info): Ditto.
29 (build_section_table): Ignore zero-length sections.
30 * language.c, printcmd.c: Lint.
31 * language.h (get_frame_language): Declare.
32 * saber.suppress: update.
33 * stack.c (find_relative_frame): Remove complex code that was
34 #if 0'd, stick with simple code. Lint.
35 * saber.suppress: Update a bit.
36 * symfile.c (add_symbol_file_command): Add "?" to question.
37 * utils.c (parse_escape): Avoid \a due to bdead compilers.
38 * value.h: Declare typedef_print.
40 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
43 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
44 (Reported by Mark Peek <mark@imagen.com>.)
46 * solib.c (solib_map_sections): Relocate all sections, even
47 though only the text section's size is tracked. Mark ld_text
48 for eventual elimination as we generalize to N sections.
50 * infrun.c (wait_for_inferior): Don't check if the PC is in a
51 call_dummy if we were stopped by a random signal that is being
52 passed to the program. This produced wierd results when calling
53 functions in the inferior and signals (e.g. SIGALRM) were in use.
55 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
57 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
58 Bugfix from Paul Eggert <eggert@twinsun.com>.
59 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
60 * valprint.c (print_floating): Print 9 digits for IEEE floats.

69 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
73 * Makefile.in (VERSION): Set to 4.1.
74 * language.c (set_language_command): Print useful help message,
75 and restore the language string after giving help.
76 * valprint.c (typedef_print): Print typedef in C or M2.
77 * symtab.c (list_symbols): Use it.
78 * main.c (main): Avoid any output before (gdb) prompt when -q.
79 * language.c (set_language_command): Handle errors by restoring
80 the language string to its current state (fix from A. Beers).
81 * doc/gdbint.texinfo: Roll in information from README. Rearrange
82 "how to install" and "how to print the doc" stuff so it drops
84 * configure.in: Rename rtpc CPU to romp to match config.sub.
85 * README, WHATS.NEW, TODO: Update for gdb-4.1.
87 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
89 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
90 autoloading shared libs, copyright etc on GDB startup, clean up $_
91 and $__ index refs, set/show listsize and related updates to list
92 cmd. New host/target configs.
94 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
96 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
97 from main Makefile.in version definition
98 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
100 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
102 * doc/gdb.texinfo: merge new language-switching and lang-specific
105 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
107 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
108 compilers (which may lack stddef.h).
110 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
112 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
113 N_WARNING are the same except for the N_EXT bit, so just use their
114 values alone, rather than OR-ing them with N_EXT.
116 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
118 * mipsread.c (parse_lines): Deal with negative extended line
121 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
122 global symbol conflicts.
124 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
126 * .gdbinit: Move 'set complaints' to top, so it runs even in
127 case we aren't debugging GDB.
128 * language.c (_initialize_language): Fix type check and range
129 check documentation strings.
130 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
131 language.c can use it. (Though language.c should really not be
132 handling warnings/errors the way it does, FIXME.)
133 * symtab.c (lookup_primitive_type): const lint.
135 Bugfix from Peter Schauer:
136 * source.c (lines_to_list): Make signed, to avoid comparison
137 going unsigned and complaining that -3 is too high for 21 lines.
138 * stack.c (lines_to_list): Ditto.
140 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
142 * Makefile.in (HFILES): Add minimon.h.
143 (VERSION): Roll version number to 4.0.95.
144 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
145 New rules for building distributions. Normal distribution
146 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
147 one level up from here; it calls make-proto-gdb.dir to build a
148 directory `proto-gdb' which is an image of the release. The old
149 `gdb.tar.Z' rule still works too.
150 * config.sub, configure: Roll in latest from ..
152 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
154 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
155 new-target, and new-config chapters; fix minor typos; come closer
156 to usual GNU markup conventions for @file @samp @code @var.
158 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
160 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
161 * mipsread.c (parse_partial_symbols): Enter the name of all
162 structs/unions... into the psymtab so we can access them if the
163 symtab is not read in.
164 * mips-tdep.c: Remove some unneeded #includes.
165 * xconfig/dec3100: Add HAVE_STRSTR.
167 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
169 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
170 * c-exp.y, m2-exp.y: Lint.
171 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
172 * valprint.c (val_print_fields): Check for stub type.
173 * mipsread.c (_initialize_mipsread): Avoid using
174 builtin_type_void at initialize time.
175 (mipscoff_symfile_read): use it now.
177 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
179 Merge multiple-language support, and partial Modula-2 support,
180 from Andrew Beers <beers@cs.buffalo.edu>.
182 * i387-tdep.c: New file, consolidates most 80387 support,
183 and eliminates host dependency on double<->extended conversions.
184 * i386-xdep.c, symm-xdep.c: Remove most 387 support.

199 (read_range_type): Rename MAX_OF_TYPE to MAX_OF_C_TYPE, etc.
200 #if 0 out its uses, though, since they set a dead value.
201 * coffread.c (end_symtab): Use allocate_symtab.
202 (process_coff_symbol): #if 0'd for functions and params as above.
203 (read_enum_type): Recognize Modula-2 BOOLEAN.
204 * symtab.c (add_param_to_type): #if 0'd function to add a
205 parameter type to a function type's field list.

213 * breakpoint.c (breakpoint_cond_eval): Use new value_true to test
214 breakpoint condition language-independently.
216 * parse.c: New file with the common code remains of expread.y.
217 * parser-defs.h: New file with common declarations from expread.y.

221 * expread.y, expread.tab.c: Remove.
222 * breakpoint.c, eval.c, printcmd.c, expression.h: Use

226 * symtab.h (enum languages): Move to defs.h.
227 (enum type_code): Add TYPE_CODE_CHAR and TYPE_CODE_BOOL.

276 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
278 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
279 entries are enclosed herein. Not all of these changes
280 have been merged into the master GDB sources -- check the
281 ChangeLog above here for the merge log.
283 Mon Jun 3 17:05:45 EDT 1991
285 m2-exp.y Created. Tested outside of GDB for a few days. Proper
286 operators were added, C specific operators and tokens
287 removed. yylex() revamped to some extent. Still things
288 missing from the grammar, such as sets.
289 Tested for two weeks in GDB v3.5.
291 Tue Jun 11 17:23:48 EDT 1991
293 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
294 so they are built-in. Sort of a hack.
296 Fri Jun 14 12:53:51 EDT 1991
298 m2-exp.y Added range checking for numeric constants. Any numeric
299 constant is assumed to be of builtin type INTEGER unless:
300 (1) it is octal or hexadecimal, in which case it is a
301 CARDINAL; (2) it is too big to fit into an INTEGER, in
302 which case it is a CARDINAL.
303 eval.c Added simple range checking for +, -, and * on integers.
304 Doesn't work very well for *, since 6 * 1,000,000,000 =
305 1,705,032,704, which fails the simple test of result >=
306 first_operand, no matter in what order the operands are.
308 Tue Jun 18 14:11:30 EDT 1991
310 Broke the parser into parts, one containing the C grammar and the other
311 containing code to be shared by all of the grammars.
313 The following files no longer exist:
318 The following files were added:
320 c-exp.y (The C grammar)
321 m2-exp.y (The Modula-2 grammar)
322 parser-code.c (Code that is shared by the above grammar)
326 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
327 now necessary to use the Bison compiler compiler, since it
328 will generate function/variable prefixes other than yy.
330 Tue Jun 18 16:47:49 EDT 1991
332 symtab.[ch] Added the external variable working_lang, than holds the
333 value of the current working language.
334 Added the ennumerated type language_mode, with the values
335 language_auto and language_manual, the former meaning that
336 GDB sets working_lang as needed, and the latter meaning
337 that the value of working_lang is totally under user
339 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
340 REAL, BOOLEAN and CHAR. Also added the type codes
341 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
342 utils.c Added set_language_command and show_language_command to
343 implement the GDB support commands "set language" and
345 expression.h A number of identifiers were added to the type exp_opcode
346 to facilitate Modula-2 builtin functions, integer
347 division, and array indexing.
349 Wed Jun 19 13:25:58 EDT 1991
351 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
352 if the language specified by working_lang requires the use
353 of strict typing of expressions. Eventually, even this
354 will be able to be changed by the user.
355 Added the macro RANGE_CHECK, which evaluates to non-zero
356 if the language specified by working_lang requires the
357 checking of a value against the domain of its type.
358 Eventually, even this will be able to be changed by the
360 language.[ch] Predicates involving types (simple_type, ordered_type,
361 same_type, integral_type, numeric_type, character_type,
362 boolean_type, float_type) are added. These predicates are
363 based on the current value of working_lang, and are handy
366 Wed Jun 19 15:39:34 EDT 1991
368 eval.c Added the function type_array_rank which computes the rank
370 valarith.c Added the funtion value_bool, which when given a integer
371 value.h value (ie. struct value *) as an argument, it returns a
372 boolean value (ie. struct value *) true if that integer
373 is non-zero, and a boolean value false otherwise.
374 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
375 will print out properly.
377 Wed Jun 19 16:36:34 EDT 1991
379 valops.c Added the function value_capitalize, which returns it
380 value.h argument capitalized if its argument is a lowercase
381 letter, or the argument unchanged if its argument is not a
383 valarith.c Added the function range_check_p, which returns non-zero
384 value.h if its value argument is between the integral bounds upper
386 Added the function range_check_enum_p, which makes sure
387 that its value argument is a valid member of the domain of
389 Added the function range_check_range_p, which makes sure
390 its value argument lies between the upper and lower bounds
391 of its type argument, which must be a ranged type.
392 Added the function check_array_index, which range and type
393 checks an index of an array.
394 Added the function value_multi_subscript, which computes
395 array[idx1,idx2...idxN], given a value array and an array
396 of values representing indicies.
397 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
398 unpack_long to work with TYPE_CODE_BOOL and
401 Wed Jun 19 18:04:08 EDT 1991
403 symtab.c Stored pervasive types in a structure and make
404 lookup_pervasive_type() a lookup function that was based
405 on working_lang. If lookup_pervasive_type() returned
406 non-zero, then that value was returned (a fix, since
407 before it simply wouldn't return the pervasive type.)
408 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
409 non-zero if the language specified by working_lang means
410 "conversion" when it says "cast".
411 valops.c Added the function value_real_cast(), which performs a
412 value.h *cast*, not a *conversion*, which is what value_cast()
413 does when it can. In particular,
414 value_cast(<float_type>,4) = 4.0, while
415 value_real_cast(<float_type>,4) = some mess.
416 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
417 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
418 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
419 and MIN on integral types. *NOTE*: These are currently
420 hardcoded to work only if there are 8 bits per storage
422 eval.c Made logical functions call value_bool to return a
423 properly typed boolean value, based on working_lang.
425 Thu Jun 20 11:55:27 EDT 1991
427 valprint.c Types now print out in a Modula-2 fashion. This works for
428 the cases when the type is printed out step-by-step, that
429 is, it doesn't work when the name of a structured type
430 (which includes the keyword "struct", etc.) is simply
432 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
433 since type specifications in C and Modula-2 are very
434 different. The C printing of a type is very recursive,
435 whereas in Modula-2 it is generally very simple. C has
436 type prefixes and suffixes, which have no real analogue in
437 Modula-2. Maybe type_print() should call a language
438 specific type printer. This is also advantageous if we
439 compile GDB to exclude some of the languages. We'll just
440 leave those functions out.
442 Thu Jun 20 16:57:10 EDT 1991
444 dbxread.c When reading the complete symbol table in (via
445 psymtab_to_symtab()), the number and types of function
446 arguments are added to a function type. define_symbol()
447 calls add_param_to_type() to accomplish this.
448 Assumption: when we come across a function definition
449 (N_FUN symbol with an 'f' or 'F' in the name), its
450 arguments will appear before another function definition.
451 When a function is found, a pointer to its type is placed
452 in the global in_function_type. Changes that
453 add_param_to_type() makes are to this global.
454 valprint.c The type of a function now includes (for Modula-2) the
455 types of its parameters.
456 eval.c Type checking and a check for the proper number of
457 arguments is now done for function calls. Not sure of the
458 impact this has on C++ member function yet.
460 Thu Jun 20 19:58:48 EDT 1991
462 valprint.c Rewrote the type printer. Broke it into two language
463 specific parts, adding the functions type_print_m2() and
465 An unfortunate consequence is this: if you debugging a C
466 program in Modula-2 mode (why?), info types does not work
467 well with regular expressions, since the types are printed
468 out in Modula-2 terminology, but stored in C terminology.
469 language.[ch] Added the functions new_type_last(), type_keyword(), and
470 type_sep() to aid in the printing of typedefs.
471 symtab.c Made the printing of typedefs as language independent as
472 possible through calls to new_type_last(), type_keyword(),
475 Fri Jun 21 11:50:26 EDT 1991
477 dbxread.c Check all incoming ennumerated types. If it looks like
478 Modula-2's BOOLEAN type, then change the type_code of the
479 type to TYPE_CODE_BOOL so we can process it as a boolean
481 valprint.c Replaced some of the 0x%x with calls to sprintf and
482 hexformat() in val_print().
483 language.[ch] Added the function hex_to_string(), which converts its
484 integral argument to a hexadecimal number (format is
485 language based) and returns the result as a string.
487 Mon Jun 24 12:25:07 EDT 1991
489 valprint.c Some functions call type_print_1() directly, instead of
490 value.h using type_print(), so they can specify where (column) to
491 print things. Since type_print() takes care of language
492 dependence, that needs to be called first. Added a
493 parameter depth to type_print() (so it is now like
494 type_print_1). Changed type_print to type_print_at, and
495 made type_print a macro that passes a depth argument of
497 symmisc.c Changed all calls to type_print_1 to calls to
499 Makefile.dist Made it possible to build GDB for a specific set of
500 depend languages. Do this by passing a definition for the macro
501 LANGS to make. LANGS should be a string containing a
502 space-separated list of language names (ie. LANGS="c m2").
503 The default is to build all languages. Note that grammar
504 files must follow the naming convention of <lang>-exp.y.
505 gdb.lang This holds the current value of the LANGS macro. It is
506 examined every time make is called, and is updated if
508 eval.c Added #ifdef _LANG_<lang> to these files.
509 expread.c Still need to add them to dbxread.c and coffread.c.
517 Mon Jun 24 16:33:11 EDT 1991
519 language.[ch] Added the functions hexformat_pre() and
520 hex_to_string_pre(), which take a prefix argument to
521 include in the format string. Thus, hexformat_pre("08") will
522 return "0x08x" (if the working language is language_c).
523 Made hexformat() and hex_to_string() calls to the above
524 with "" as the prefix argument.
526 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
527 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
528 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
529 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
530 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
531 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
532 valprint.c, vax-pinsn.c
534 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
535 calls to hexformat() and hex_to_string(). Format strings without
536 the leading "0x" were ignored.
538 depend Updated to take the above into account.
541 Tue Jun 25 15:27:18 EDT 1991
543 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
544 and type_check_t to keep track of the current state of
545 range and type checking.
546 main.c Added the variables range_mode, range_check, type_mode,
547 and type_check to record the current state of range and
548 type checking. Added initialization code to main().
549 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
553 Tue Jun 25 17:57:08 EDT 1991
555 dbxread.c process_one_symbol() updates the variable (enum language)
556 source_lang based on the extension of the filename
557 contained in the N_SO sybmol that started this symtab.
558 When end_symtab() is called, the value of source_lang is
559 put into the language field.
560 stack.c select_frame() sets working_lang (and possibly type_check
561 and range_check) to the language field of the symtab
562 associated with the frame that is selected if working_mode
563 is language_auto. If working_mode is language_manual, a
564 warning is printed and working_lang is not set.
565 language.c Added the function set_type_range(), which sets the value of
566 type_check and range_check (if their modes call for
567 automatic setting) based on the current value of
568 working_lang. A non-zero argument will cause the current
569 settings to be output.
572 Wed Jun 26 14:51:40 EDT 1991
574 eval.c Added range checks on assignment.
575 m2-exp.y Added the grammar for sets to the language. Currently,
576 these do not do anything except print an error message.
578 Wed Jun 26 17:01:04 EDT 1991
580 m2-exp.y Added the ability for parse_number() to parse negative
581 numbers. A global flag is set upon encountering a unary
582 minus. This was done to make, for example, 1 parse as a
583 CARDINAL, and not as an integer, per Wirth's examples in
584 Programming in Modula-2 ed.4.
585 valprint.c Added support for "set radix 2" by then setting
586 output_format to 't'.
587 eval.c Implemented range checking on subrange types. Added calls
588 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
589 Implemented MIN and MAX for ennumerated types. The
590 minimum value of an ennumerated type is defined by Wirth
591 as the first identifier, and the maximum as the last.
592 m2-exp.y Made octal numbers ending with "B" be characters and those
593 ending with "C" be numbers, per Wirth's book. (p. 34)
595 Thu Jun 27 14:11:52 EDT 1991
597 stack.c select_frame() now only sets working_lang, it does not
598 notify the user. If working_mode is language_manual, then
599 a warning is issued once.
600 main.c At the end of each call to execute_command(), working_lang
601 is checked against the local static (enum language)
602 current. If they differ and working_mode is
603 language_auto, the new settings of language, type and
604 range checking are printed out.
605 stack.c Modified frame_info() to include the language of the
606 current frame in the output of "info frame".
607 language.[ch] Added the function language_str() which returns the name
608 of the current language.
610 Fri Jun 28 15:33:14 EDT 1991
612 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
613 the language. INCL and DECL currently cause an error,
614 since sets are not implemented yet. INC and DEC are
615 implemented as PREINCREMENT/PREDECREMENT with one
616 argument, and as ASSIGN_MODIFY with two arguments.
617 eval.c Added type checking to the above cases.
618 value.h Added not_lval_constant to the lval_type ennumerated type.
619 not_lval_constant means that the value is a constant
620 value; that is 3 or 'a' or TRUE, not as in a constant
621 identifier. This is used to help coerce numbers such as 3
622 to either signed or unsigned numbers.
623 valops.c Added the function value_coerce_constants() which coerces
624 constant integers as following: if one is a constant and
625 the other is not, the constant's type is set to the type
626 of the other argument. If both are constants and one is
627 signed, the other is converted to a signed constant.
629 Sat Jun 29 17:26:29 EDT 1991
631 valarith.c Added a better range checker. It now checks range
632 (successfully) on integral operations [+-] (signed and
633 unsigned) for any C sized type. Still does not work well
635 int_in_size() returns an integer that is coerced to fit into
636 specified number of bytes.
638 Mon Jul 1 13:04:14 EDT 1991
640 language.[ch] Added the function binop_result_type(), which returns the
641 builtin (struct type *) type that would be the result of a
642 binop on the two values V1 and V2.
644 Wed Jul 3 19:22:53 EDT 1991
646 source.c Extended source_info() to include the source language in
647 the output from "info source".
649 Fri Jul 5 13:48:52 EDT 1991
651 utils.c Moved the support functions for the GDB set/show commands
652 dealing with language into language.c.
653 language.c Added the function language_info(), which displays info
654 about the current working language, type and range check
655 settings. Called via the GDB command "info language".
656 Added an initialization routine _initialize_language(),
657 that sets defaults for the language, type and range
658 variables and sets up the new GDB commands.
659 main.c Language setup moved to language.c.
662 Mon Jul 8 10:10:22 EDT 1991
664 valarith.c Debugged the range checker for arithmetic. Still does not
665 work for multiplication very well.
667 Mon Jul 8 12:40:37 EDT 1991
669 language.[ch] Added the function value_true() which returns non-zero if
670 its argument represents a boolean true value.
671 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
672 check the truth of an expression.
674 Thu Jul 11 12:51:34 EDT 1991
676 language.[ch] Added the predicate structured_type(), which returns
677 non-zero if the argument is a structured type.
678 Added the predicate pointer_type(), which returns non-zero
679 if the argument is a pointer type.
680 eval.c Added the ability to do addition and substraction on
681 pointers and integers. This case simply bypasses the
684 Thu Jul 11 14:41:42 EDT 1991
687 Added the symbol N_DEFD (0x4a) which is a definition
688 module dependency that is used by the GNU Modula-2
689 compiler and the linker. It is not important to GDB,
690 except that [dbx|coff|mips]read.c should ignore these
693 Fri Jul 12 16:07:00 EDT 1991
695 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
696 0 in val_print(). Also added statements to the else part
697 to coerce type (argument to val_print) to a pointer type
698 if it is an "array of unspecified length".
699 valops.c Added the function value_m2_string(), which returns a
700 (value) value which is a constant string, whose type is
701 (ARRAY [0..n] OF CHAR). The length field of the type
702 structure is set to zero, so it will be interpreted as an
703 "array of unspecified length".
704 stack.c Moved the language/frame mismatch check to
705 main.c:execute_command().
706 main.c The working language is recorded each time
707 execute_command() is executed. If working lang has
708 changed during its execution, then the new
709 language/type/range info is printed out for the user. If
710 the working language does not match the language of the
711 frame, a warning is issued.
713 Sat Jul 13 16:16:39 EDT 1991
715 eval.c Moved all the type-checking stuff for operators to
716 language.[ch] language.c. This is so we can keep language-specific
717 stuff (like for what type operators are defined) in
719 language.[ch] Added the function binop_type_check(), which checks to see
720 if its two (value) arguments are type-compatible with its
721 opcode argument. The opcode should represent an operation
722 involving an operator. Also added the macro function
723 unop_type_check, which calls binop_type_check with a
724 NULL second argument.
725 expprint.c Added Modula-2 operators to the op_print_tab, so info
726 expression.h break works correctly. Also added "op_string", which
727 returns the string corresponding to the (enum exp_opcode)
728 opcode that is its argument.
731 Sat Jul 13 18:26:18 EDT 1991
733 coffread.c Added code to record the type of function arguments with
734 each paricular function. Code is very similar to that
736 dbxread.c Moved add_param_to_type() to symtab.c
737 symtab.[ch] Added function add_param_to_type() from dbxread.c
739 *** NOTE: The above additions have not been tested.
741 Mon Jul 15 12:50:47 EDT 1991
743 langauge.[ch] Added the functions type_error and range_error, which work
744 like error() except if the type/range mode is set to
745 *_mode_warn, then they do not do a return_to_top_level(),
746 but merely print a warning.
747 Also changed [set|show]_[type|range]_command() to support
748 the new "warn" feature.
750 Thu Jul 18 17:50:54 EDT 1991
752 mipsread.c Added code to record the type of function arguments with
753 each particular function. Code is very similar to that
756 *** NOTE: The above additions have not been tested.
758 Fri Jul 19 11:19:10 EDT 1991
760 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
761 UMIN_OF_SIZE, which when given a size of a numeric type,
762 return the maximum and minimum value it can hold. UMAX...
763 and UMIN... return the result for unsigned types.
764 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
765 struct types. They call above macros.
766 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
767 avoid a name conlict with the above.
768 c-exp.y Added range checking on numeric constants in
769 parse_number() for completeness.
770 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
771 return 0 if working_lang is not language_c.
773 Thu Aug 8 14:17:22 EDT 1991
777 breakpoint.c Documentation strings of some commands changed to
778 eliminate the references to the C language where
781 Tue Aug 13 15:48:03 EDT 1991
783 m2-exp.y Added qualified identifiers to the grammar. The semantics
784 are slightly different from those of the GDB operator ::
786 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
787 type_exp, where type_exp is any valid type expression.
789 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
790 printcmd.c Modified ptype_command() so it actually parses the input
791 (necessary for type expressions with scope qualifiers).
792 Added the function ptype_eval() which expects an
793 expression composed of one OP_TYPE element.
794 *.[ch] Replaced all occurences of parse_c_expression with
796 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
798 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
800 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
802 Small fixes from Peter Schauer:
804 * infrun.c (child_attach): Lint.
805 * solib.c (find_solib): Handle shared libs version 2.
807 Small fixes from David Wood:
809 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
813 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
814 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
816 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
817 chars_per_line is at maximum (user typed `set width 0'). Fix
818 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
820 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
822 * coredep.c: include ptrace.h where necessary.
823 * mipsread.c(parse_lines): fix unsigned char problem that was
824 messing up line numbers on SGI's and possibly other MIPS based
826 * infrun.c (child_create_inferior): use better test to check
827 return val from setpgrp().
828 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
829 for sgi/irix support.
831 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
833 * mipsread.c (parse_symbol): Put non-static procedures
836 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
838 Patch together `text_start' and `text_end' for 29K port.
840 * exec.c (exec_command): If NEED_TEXT_START_END, define the
841 variables and set them based on the exec file.
842 * am29k-tdep.c: declare text_start.
843 * valops.c (call_function_by_hand): declare text_end.
845 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
846 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
847 because machines that do this will also have to know to
848 set NEED_TEXT_START_END. Besides, it was a redundant way to
850 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
851 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
854 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
856 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
858 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
859 Pass MUNCH_DEFINE to munch whenever we run it.
860 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
861 format string; use 0x%x instead.
862 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
863 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
864 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
865 * inflow.c: Handle `short' process group IDs.
866 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
867 and check for ptrace errors.
868 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
869 (coff_symfile_init): Initialize text_bfd_scnum.
870 (read_coff_symtab): Use it to find the text [and absolute?] sections.
871 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
872 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
873 Merge target arm case with other "easy" cases. Add target
874 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
875 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
877 * minimon.h, remote-adapt.c, remote-mm.c: Add.
878 * munch: Cope with RT/PC putting fns in data segment.
879 Restore ability to override `nm' by specifying MUNCH_NM.
880 * xconfig/rtbsd, xconfig/ultra3: New host systems.
881 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
882 and remote-adapt. Remove encapsulated coff #define's (the
883 support should go in BFD, and gdb shouldn't know or care).
884 * tconfig/a29k-kern: Same, but for remote kernel debugging.
885 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
886 * tm-29k.h: Update BADMAG (though it should go away).
887 Allow the register definitions to be overridden in another
888 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
889 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
890 DUMMY_SAVE_GR96, for handling kernel calling conventions
891 that use GR64+ rather than GR96+.
892 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
893 remote debugging of Ultra3 kernel. Includes tm-29k.h and
894 overrides various things.
896 * remote-mm.c (mm_attach, mm_wait): Handle attach like
897 child_attach does, making a clean stop in the newly attached
901 * coffread.c: Make coffread independent of any particular
902 variant of COFF. Avoid #include-ing any particular one except
903 internalcoff.h. BFD now passes key values for symbol reading
904 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
905 and the symbol masks and shifts); use them.
906 Remove obsolete end_of_text_addr.
908 * exec.c: Remove unused include files.
910 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
912 * Makefile.in (documentation targets): Pass $(M4).
913 Bugfix from eggert@twinsun.com (Paul Eggert).
915 * stack.c (down_silently_command): Check for stack existence.
917 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
919 * Makefile.in (VERSION): Update to 4.0.3.
921 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
923 * core.c (core_file_command): Print frame at coredump with
924 its level number, by calling print_stack_frame.
925 * frame.h: Add selected_frame_level, print_stack_frame.
926 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
927 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
928 Change print_sel_frame and print_selected_frame callers to
931 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
932 * symfile.c (free_named_symtabs): Ditto.
933 * main.c (main): wrap_here needs an arg.
934 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
935 (solib_add): Avoid noise.
936 (solib_create_inferior_hook): Lint.
937 (sharedlibrary_command): Move dont_repeat to here.
938 * utils.c (error): Call wrap_here to force buffered output.
940 Small patches from Peter Schauer:
942 * coffread.c (start_symtab): Free any existing line_vector before
944 (read_coff_symtab): Ditto for type_vector.
946 * source.c (lines_to_list): New variable, replacing function.
947 (all uses): Use as variable.
948 (_initialize_source): Add 'set listsize' and 'show listsize'.
949 * utils.c (lines_to_list): Remove function.
950 * stack.c (print_frame_info): Use as variable.
951 * defs.h (lines_to_list): Remove declaration.
953 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
955 * breakpoint.c (insert_breakpoints): Restore warning about
956 the program might be running in another process, but only for
957 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
958 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
960 * utils.c (error): if error_pre_print is set, print the string
962 * main.c (main, print_gnu_advertisement, print_gdb_version):
963 Reformat legalese so it always prints, but acts as an "I'm here"
964 message while symbols are being read. If any errors occur,
965 print a few newlines to set off the message and start it at the
966 left margin. Remove mention of "help" command, and don't yak
967 about symbol reading.
968 (catch_errors): Error string is now printed first in case of
970 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
971 suggest the "help" command.
973 * Makefile.in (VERSION): Set to 4.0.2.
975 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
977 * .gdbinit: Remove useless "rr" command. Set complaints
978 to 1 for people debugging gdb.
980 * breakpoint.c, remote-vx.c: Reword strings printed by
981 catch_errors callers.
983 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
985 * WHATS.NEW: "history write -> history save". Doc "write on/off".
986 (Fix from kenc@viewlogic.com.)
988 Fix some infrastructure to be able to cope with host and target
989 machines with different sized basic types (ints, ptrs, etc).
990 (Idea from pierre@la.tce.com (Pierre Willard).)
992 * values.c (value_from_longest): Rename from value_from_long.
993 Handle pointer types as well as integers, so that targets with
994 different pointer sizes from the host can be accomodated.
995 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
996 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
997 uses of value_from_long to value_from_longest.
998 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
999 the correct pointer type to value_from_long{est}.
1001 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1003 * remote-vx.c: Remove obsolete code for calling functions via
1004 vxworks kludge interface (it referenced value_from_long).
1006 * valops.c (value_string): Find malloc with lookup_misc_func, not
1009 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1011 Make writing to files work properly. (Fixes to BFD are also needed.)
1013 * core.c (core_open): Open file ourselves, read or r/w, depending on
1014 write_files. Use bfd_fdopenr.
1015 * gdbcore.h (write_files): New variable.
1016 * exec.c (write_files): Define variable, add set&show for it.
1017 (exec_file_command): Use write_files to open for read or r/write.
1019 Make shared library reading happen automatically. These changes
1020 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1022 * inferior.h (stop_soon_quietly): Add to exported variables.
1023 * infrun.c (child_create_inferior): call solib hook, if defined.
1024 (child_attach): call solib hook, if defined.
1025 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1026 (find_solib): Use lookup_misc_func rather than hand-rolled.
1027 (symbol_add_stub): New stub for catch_errors.
1028 (solib_add): Avoid output if !from_tty. Catch errors rather
1029 than just calling symbol_file_add and bombing.
1030 (solib_create_inferior_hook): Interface with the target process
1031 to let it read and alloc shared libs, then figure out what it did.
1033 * core.c (validate_files): Fix typo, soften warning.
1034 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1036 * utils.c (fputs_demangled): Avoid duplicate printing if
1037 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1039 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1040 (Fix from pierre@la.tce.com (Pierre Willard).)
1042 * main.c (catch_errors): Change argument to a char * from an int,
1043 since a char * can point to a struct full of glop, but an int
1044 is not guaranteed to be able to hold a pointer.
1045 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1046 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1047 * core.c (core_open, solib_add_stub): Adapt.
1048 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1050 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1052 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1053 by adding .NOEXPORT target.
1055 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1059 * Makefile.in (VERSION): Roll to 4.0.
1060 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1062 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1064 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1067 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1070 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1072 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1073 reflect above name change
1075 * WHATS.NEW: correct pointer to refcard.
1077 * doc/gdb.texinfo: update New Features, Installing
1079 * doc/gdbint.texinfo: add short description of configure +template
1081 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1083 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1085 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1087 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1088 tar file, add dependencies for referenced doc files.
1090 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1092 * coffread.c, symfile.c, stack.c: saberized.
1094 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1096 * doc/refcard.tex: permuted Essential Commands sec
1098 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1100 set/show symbol-reloading
1101 default set complaints 0
1103 RET-repeat disabled after prompted long displays
1104 processID (attach) interpretation of 2nd GDB cmdline arg
1106 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1108 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1109 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1110 breakpoint.c, main.c: lint.
1112 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1114 Install new configuration scheme for GDB and friends.
1116 * config.sub: Translate ordinary names to three-part names.
1117 * configure: Use three-part names internally.
1118 * configure.in: Translate three-part names to filenames.
1120 * README, WHATS.NEW: Update for gdb-4.0.
1121 * Makefile.in: Roll VERSION to 3.99.
1123 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1125 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1126 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1127 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1128 to single structures rather than arrays; when passing
1129 their address, use &. This avoids trouble with bdead compilers.
1130 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1131 instead. This avoids portability headaches.
1132 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1134 * source.c (open_source_file): Avoid ANSI const bdeath by
1135 skipping declaration and then casting result value.
1136 * tm-hp300bsd.h: Clarify comment.
1137 * utils.c (strstr): Result is const char *; ANSI bdeath.
1138 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1139 since system include file defines it differently from "defs.h",
1140 though the two are equivalent for our purposes.
1141 * tconfig/hp300bsd: Add m68k-tdep.o.
1143 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1145 * tconfig/sun*4: Remove warnings about system assembler.
1147 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1149 * mcheck.c: Avoid warning about undeclared abort fn.
1150 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1151 it causes recursive calls to error() when used in cleanups.
1152 To do so requires that we make it a function, so we do.
1153 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1154 * utils.c (do_cleanups): Remove the current cleanup from the
1155 chain *before* calling it, in case error() is called from it.
1156 The result won't be pretty, but won't be an infinite loop either.
1158 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1160 * dbxread.c (read_struct_type): Grok anon structs for C++.
1161 (vb_name, vptr_name): Null terminate these strings.
1163 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1165 Minor bug fixes from BSD Net2 gdb:
1167 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1168 returns 0, there is no previous frame.
1169 * breakpoint.c (commands_command): If !from_tty, don't call
1170 input_from_terminal_p().
1171 * dbxread.c (record_misc_function): Speed up slightly.
1172 (compare_psymbols): Ditto.
1173 * infcmd.c (do_registers_info): Take a second argument to
1174 determine whether to print float registers. "info registers"
1175 does not do so anymore. "info all-registers" does, now.
1176 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1178 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1179 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1183 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1184 executing_breakpoint_commands if we are interrupted by error.
1185 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1186 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1187 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1188 catch_errors() so we can setup the frame regardless of whether
1189 the shared libs work.
1190 * ieee-float.c (double_to_ieee_extended): Get exponent from
1191 right place in little-endian systems. From John Carey.
1193 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1195 * main.c: Remove unused terminating_signals and catch_termination().
1196 (long_options): Terminate with a zero element.
1197 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1198 (gdb_readline): Make call-compatible with readline.
1199 (init_signals): Improve comments re vfork vs. signal.
1201 * utils.c (prompt_for_continue): Use new gdb_readline().
1202 If we prompt for continuation, we don't let CR repeat the previous
1203 command, once we get back to a prompt. It's too easy to keep
1204 hitting CR, expecting "--more--" prompts, and have some long
1205 command start repeating on you.
1207 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1209 * blockframe.c (frameless_look_for_prologue): Speed up by
1210 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1211 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1212 Define two variants, one faster.
1213 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1214 and return zero, rather than giving an error.
1215 (setup_arbitrary_frame): Initialize the PC in the new frame.
1216 (skip_prologue): Add a second arg saying whether we're just
1217 checking for a frameless function or not.
1219 * core.c (core_open, core_close, core_xfer_memory): Move
1220 section table pointers and bfd* into the target_ops.
1221 (core_open): Allow errors in shared lib reading, etc.
1222 (core_files_info): Describe shared library sections.
1224 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1225 exec_files_info, set_section_command): Move section table
1226 pointers and bfd* into the target_ops.
1227 (add_to_section_table): Add BFD to section table.
1229 * target.c (target_xfer_memory, target_info): Pass target to
1230 xfer_memory and target_info functions.
1233 * gdbcore.h: Move struct section_table.
1234 * target.h: New home of struct section_table.
1236 * solib.c (solib_add): New argument is the target_ops whose
1237 section list is to be added to, if any. Reallocate the
1238 sections in that target to add any that come from shared libs.
1239 (throughout) so_sections renamed to sections.
1240 (solib_xfer_memory): Deleted.
1241 * tm-sunos.h (SOLIB_ADD): Add target argument.
1242 (SOLIB_XFER_MEMORY): Delete.
1244 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1245 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1246 from target_ops. It's the same on all targets. Add two section
1247 pointers to target_ops.
1249 * stack.c (find_relative_frame): Dump ancient algorithm for
1250 "down", just use handy "next" pointers.
1251 (frame_command): Don't error if there is no stack; let user
1254 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1255 modifies static state in the parent process; new_tty itself
1256 runs in the child and modifies the child's file descriptors
1257 to match the saved static state.
1258 * infrun.c (child_create_inferior): Call new_tty_prefork,
1261 * infptrace.c (child_xfer_memory): Add ignored target arg.
1262 * remote-eb.c (eb_xfer_inferior_memory): ''
1263 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1264 * remote-vx.c (vx_xfer_memory): ''
1265 * remote.c (remote_xfer_memory): ''. Rename from
1266 remote_xfer_inferior_memory.
1268 * main.c (main): Only try to attach "corefile" argument if
1269 it starts with a digit.
1271 * symfile.c (symbol_reloading): New "set/show" variable.
1272 (symbol_file_add): Shorten message about symbol reading.
1273 (add_symbol_file_command): Merge with add_syms_addr_command,
1274 since this should work on all targets now.
1275 (stop_whining): Default to zero, to shut up complaints
1276 about bad symbol tables on many systems.
1277 (free_named_symtabs): Just exit unless symbol_reloading.
1279 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1280 and add comment explaining shared library screw.
1282 * source.c: #if defined => #ifdef.
1284 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1286 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1288 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1290 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1291 (doc/Makefile knows how to make one for local config)
1293 * Makefile.in: use doc/Makefile for doc targets
1295 * doc/Makefile: GDB documentation now has its own Makefile
1296 doc/refcard.tex: renamed from "gdbrc.tex"
1297 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1298 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1301 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1303 * values.c (baseclass_addr): When reading target memory, use the
1304 length of the basetype, not the upper type. We've only malloc'd
1305 enough space for the basetype, leading to errors in free().
1307 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1308 ends up as a function specially, since we know the actual type of
1309 the pointed-to address. This (somewhat) fixes display of
1310 expressions that include misc_function_vector names. Try `cond 1
1311 !strcmp("a","b")' then `i b'.
1313 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1314 The child can be proceeded from inside wait_for_inferior in
1315 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1316 getting skipped in that case.
1318 * expprint.c (print_subexp): Use filtered output, since the
1319 subroutines we call use it, otherwise the output is horribly
1320 mangled, since output of wrappable stuff comes out late.
1322 * Makefile.in: Bump VERSION to 3.98.1
1324 * infrun.c (child_create_process): Use execlp to find the
1325 shell to exec our target program. This requires some fiddling
1326 with `environ' since there is no execlpe().
1328 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1330 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1331 Minor rearrangement of refcard permits two new make targets--
1332 gdbrc.dvi DVI output for refcard, using CM fonts
1333 gdbrc.ps PostScript refcard, using PS fonts
1335 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1339 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1340 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1342 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1344 * doc/gdb.texinfo: last changes for release.
1345 Minor typo and formatting fixes; incorporated most fixes remaining from
1346 filed mail commenting on earlier drafts.
1348 Added warnings: pipes don't work in run command;
1349 conditions are converse of assertions;
1350 step over fn without debug info goes to next fn;
1351 vars may have "wrong" values near fn entrance, exit
1353 Added example from Kingston on printing repeated nonadjacent values
1355 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1356 shell mode for signals
1358 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1359 doesn't sound so much like its parent "Stopping and Continuing"; also
1360 moved entries on continue to top of section, so they don't get lost.
1362 Improved installation directions in appendix, added manual formatting
1365 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1367 * configure.in: Remove xm.h and tm.h even if we aren't linking
1368 new ones, so "./configure sun4; ./configure none" does the right
1369 thing. Assume that alldeps.mak and depend are already built in
1370 srcdir, and avoid running "make" (particularly "make depend",
1371 which involves "gcc") from inside configure. Build Makefile
1372 directly rather than building Makefile.conf first.
1373 * configure: Regenerate with above changes.
1374 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1375 to 3.98. Revise gdb.tar.Z procedure to produce a file
1376 called gdb-$(VERSION).tar.Z but which unpacks into a
1377 directory called "gdb". Move non-source files out of
1378 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1379 (depend): Don't try to do "gcc expread.y".
1380 (expread.o): Update dependencies by hand.
1382 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1385 Fixed a variety of small typos that prevented info from formatting
1386 cleanly; altered too-long heading for GPL Appendix, as discussed
1387 w/RMS; Changed date on cover to July 91.
1389 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1392 (1) Applied some fixes due to comments from Larry Breed (easier ones
1393 through chapsec 5.2)
1394 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1395 it's broken in latest texinfo
1396 (3) Introduced *some* use of [] for optional arguments, where
1397 explanation is not simpler by listing cmd w arg and cmd w/out arg
1398 separately. Still not using @deffn.
1399 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1400 couple of headings are too long. Need patches to texinfo or revision
1403 * Partial update to README (which still needs work for this
1404 release!): (1) use of configure corrected for new script,
1405 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1407 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1409 * symtab.c (lookup_symbol): Don't complain right off about
1410 no debug symbols; use the misc function vector first.
1411 (list_symbols): Use misc function vector to find symbols
1412 that don't have debug info, and print them.
1413 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1414 PC range doesn't match symtab PC range, as it does on the
1415 MIPS because our symtab reading isn't perfect.
1417 * dbxread.c (dbx_symfile_read): Make warning about
1418 "no debug symbols" slightly nicer.
1420 * source.c (select_source_symtab): If "main" symbol exists,
1421 but decode_line_spec can't find line info, don't just return
1422 a zero; try other source symtabs or give an error.
1424 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1425 their low addresses first, then rip through fixing high addrs.
1427 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1428 <runene@ifi.uio.no>.
1429 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1431 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1433 * Minor, mostly mechanical, cleanup of doc subdir for clean
1434 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1435 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1437 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
1439 Mostly MIPS and general symbol-reading fixups.
1441 * doc/gdbint.texinfo: Add documentation on symbol-reading
1444 * mipsread.c: Remove kludges around #include "ecoff.h".
1445 Remove redefinitions of a_magic, etc, no longer used.
1446 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
1447 Fix global overview comments to match symfile.c protocol.
1448 (mipscoff_new_init): Eliminate cur_hdr if we have one.
1449 (mipscoff_symfile_read): Eliminate unused code. Avoid
1450 sorting all the symtabs, when all we have read here is psymtabs.
1451 The symtabs are sorted as they are created anyway. Tell
1452 condense_misc_bunches whether we're mainline.
1453 (psymtab_to_symtab_1): Pass filename when recursing, to make
1454 stack trace more informative.
1455 (parse_partial_symbols): Assume cur_hdr as argument.
1456 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
1457 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
1458 the TYPE_NAME of char *, since that's done in symfile.c.
1459 (free_numargs, parse_symbol, add_symbol, add_block,
1460 shrink_linetable): Declare these fns void.
1461 (upgrade_type): Convert tree of if's to switch. Clean up
1462 bogus "off == 0" handling with a complaint. Avoid setting
1463 field bitpos and bitsize of array with lower and upper bounds.
1464 Check specified bitsize of elements against their actual type's
1465 bitsize, and complain if different. Complain about unknown
1467 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
1468 (psymtab_to_symtab_1): Print names of subsidiary files that
1469 are being read in. FIXME, we read far too many files. This code
1470 is not the problem, the problem is in parse_fdr where the psymtabs
1472 (cross_ref): Result should indicate that we used one aux entry
1473 normally, or two if we encountered a "next" entry. This used
1474 to leave the caller pointing at the wrong aux entry.
1475 (add_symbol): If overflowed cur_block, reallocate it larger,
1476 chase all pointers to it, and complain(), rather than clobber memory.
1477 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
1478 (new_field): Only allocate one field initially, not two.
1479 Pull ++ out of macro argument. Simplify.
1480 (_initialize_mipsread): Avoid initialization of importd
1481 global_psymbols and static_psymbols.
1483 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
1484 to properly set pst->symtab; avoid searching for it.
1485 (symfile_fns): Improve comments, add a FIXME.
1486 * dbxread.c: Update comments to reflect symfile protocol.
1487 (read_ofile_symtab, end_symtab): Return the symtab.
1488 (psymtab_to_symtab_1): Set pst->symtab.
1490 * coffread.c (coff_symfile_read): tell condense_misc_bunches
1491 whether we're mainline.
1493 * symfile.h (sym_fns): Remove unused sym_discard member.
1494 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
1496 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
1497 the environment variable is not.
1498 * infcmd.c (finish_command): Use filtered printfs.
1499 * cplus-dem.c: Add struct tags to a few unnamed structs.
1500 * valops.c (value_coerce_array): Improve comments.
1501 * valprint.c (type_print_varspec_suffix): Print array size only
1502 if greater than zero.
1503 * m88k-tdep.c: Shift some lines left by one space, that had
1504 apparently been trashed at some point.
1505 * TODO: More things to do, a few got done.
1507 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1509 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
1510 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
1512 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
1513 * expread.y, findvar.c, symmisc.c: Ditto.
1514 * printcmd.c (address_info): Update printed forms of LOC_
1515 symbols. Elim LOC_EXTERNAL.
1516 (print_frame_args): Keep track of param stack offsets before
1517 re-looking up to find the local register param is kept in.
1519 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
1520 Further integration of mipsread into gdb. Eliminate unused
1521 routines, duplicate declarations. Handle static symbols in
1522 psymtabs as well as external symbols. When reading symtabs,
1523 insert symbols into the correct block (global, static, or a local
1525 (read_mips_symtab, parse_partial_symbols): Don't pass useless
1527 (mipscoff_symfile_read): Don't call select_source_symtab.
1528 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
1529 rather than SYMBOL_VALUE.
1530 (parse_external): Comment clobbering of top_stack.
1531 (parse_partial_symbols): Update comments. Allocate and parse
1532 static symbols as well as external symbols. FIXME, enum values
1533 are not handled in this pass, but should be. Inline new_psymbol.
1534 Use SYMBOL_VALUE_ADDRESS.
1535 (psymtab_to_symtab_1): Read symbols into global static block
1536 by default (until enter some function's local block context).
1537 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
1538 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
1540 * source.c (select_source_symtab): Select a source symtab
1541 from either the symtabs or, failing that, the psymtabs.
1542 (list_command): Update error message.
1543 (forward_search_command, reverse_search_command): Use getc, not
1544 fgetc, for speed. FIXME, add comment about buffers that die if
1545 overrun by long line.
1547 * values.c (unpack_field_as_long, modify_field): Avoid shifting
1548 by an entire word, which is not portable, if we have a 32-bit
1549 field. (Code in dbxread.c already turns such bitfields, if
1550 aligned, into ordinary ints, but fixing this will help for other
1551 symbol formats and for future changes.)
1552 * core.c (core_open): Handle ANSI const brain death.
1553 * utils.c (vprintf): Fix varargs typo.
1555 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1557 * findvar.c (find_var_value): Handle &function better.
1558 * TODO: Document work needed on &fn and &array.
1559 * printcmd.c (print_address_symbolic): New arg is the prefix
1560 to print if a name is printed.
1561 (print_address_demangle): Honor "set print address" now.
1562 Use new arg above to improve spacing of output.
1563 * valprint.c (val_print): When printing function pointers,
1564 print symbolic form too.
1565 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
1567 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1569 * core.c (memory_error): Reword error msg to mislead less.
1571 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
1573 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
1574 parse_partial_symbols): Use newer BFD internals (external_filehdr
1575 and external_aouthdr), byte-swap the fields that we care about
1576 before using them, and make the file header data local to
1577 read_the_mips_symtab rather than global.
1579 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
1581 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
1582 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
1584 * main.c (command_line_input): Flush stdout and stderr
1585 before every call to readline. This reportedly fixes a bug
1586 that comes up in Sys V running emacs-gdb and/or xxgdb,
1587 when stdin/out are pipes or sockets.
1589 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1591 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
1592 Avoid declaring Makefile dependencies, because GNU Make stupidly
1593 tries to update it if we do.
1595 * coffread.c: Revise for minor changes to bfd internal coff
1598 * configure: If -template= is given a relative path, make it
1599 absolute before recurring in subdirectories.
1601 * configure, configure.in, Makefile.in: Install "configure" script
1602 as replacement for config.gdb.
1603 * config.gdb, Makefile.dist, Makefile.sdir: Remove
1604 * README: Update for configure, mostly. FIXME.
1606 * Add dec3100 as equivalent to littlemips. Indicate in all host &
1607 target config files that they are for the host. When the lines
1608 get copied into the Makefile, this makes it more obvious what's
1611 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1613 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
1614 tabs, which end up in the disassembler output inadvertently.
1616 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1618 Make it compile cleanly in an ANSI GCC2 environment.
1620 * blockframe.c: <stdio.h>
1621 * cplus-dem.c: free takes a void *, ifdef __STDC__
1622 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
1624 * defs.h (alloca): Avoid doing anything if alloca already def'd.
1625 * stddef.h, stdlib.h: Remove these files.
1626 * symtab.c: Avoid declaring qsort, close.
1627 * symfile.c: Avoid declaring close.
1628 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
1629 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
1631 Assorted other changes.
1632 * dbxread.c: include "libaout.h", not "liba.out.h".
1633 * printcmd.c (print_frame_args): Set recurse properly for
1634 indentation of struct and array parameters.
1635 * valops.c (value_cast): Allow cast to void.
1636 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
1637 single_step() in a target-independent fashion.
1638 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
1639 set up to be ready to continue. This makes us target independent.
1640 * infptrace.c (child_resume): Remove call to single_step; now
1641 can single step a SPARC target of any kind.
1643 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1645 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
1646 docn into separate sections---basically chapters, plus two loose
1647 pieces that can be configured to go in different places. This
1648 allows GNU m4 to preprocess the manual without coredumping.
1650 * Makefile.dist: tell TeX where to find texinfo.
1652 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1654 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
1655 the new target "rdl-apps.texinfo" which captures the Makefile
1656 variable that records where to find the Readline libraries.
1658 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
1660 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
1661 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
1662 * defs.h (const, volatile): Only define if not already defined.
1663 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
1665 * README: Update for release 3.95.
1666 * config.gdb: Don't create readline dir in subdir builds.
1667 * main.c: Include with "..." form for non-system include files,
1668 so "gcc -MM" for "make depend" works.
1669 Include readline files with "...h" rather than <readline/...h>.
1670 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
1672 * coffread.c: Undo minor damage done by Rich Pixley. Use
1673 different internal and external representations of COFF
1674 data structures. Use new BFD routines for swapping them in and
1676 * symfile.c (free_named_symtabs): Avoid freeing file names that
1677 are null or empty. Old i960 tools seem to produce files that
1678 claim to have empty names, causing each successive file read
1679 to blow away the previous one.
1680 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
1681 Move deferred_stores to top of file, but don't separate its
1682 #define's from its variable. Add commentary.
1683 * Makefile.dist: Fix Rich damage; undo "configure" changes in
1684 favor of keeping the (working) config.gdb. Move readline
1687 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
1689 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
1691 * infptrace.c (fetch_registers): no result, since now void.
1692 * tconfig/news: target depends on m68k-tdep too.
1694 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1696 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
1699 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
1700 applied various small fixes due to or inspired by RMS comments
1702 * doc/gdb.texinfo: finished using all RMS comments, save those for
1703 appendices on readline and cmd history (which are in other source
1706 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1708 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
1709 chapter 9; (2) documented 'break' command's menu mode for
1710 overloaded names, in response to hgs problem report C++ p-31
1712 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1714 * doc/gdb.texinfo: (1) better introductory example; (2) more
1715 consistent use of @code, @samp, @file, @kbd throughout; small
1716 cleanups to first three nodes; (3) new "Contributors" node;
1717 (4) Appendix, Renamed Commands; (5) divert specialized startup
1718 instructions to "Targets" chapter for generic manuals, while
1719 leaving them up front for manuals specific to specialized
1720 environments; (6) apply fixes from RMS comments through chapter 4.
1722 * pretex.m4: modify explanatory text slightly (and redefine
1723 "regexp") to keep GNU m4 from complaining. (It still crashes
1724 later, but one step at a time...)
1726 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
1728 * readline/readline.c (update_line): Avoid dereferencing a pointer
1729 before comparing it to its bounds. Saber caught this.
1730 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
1731 and only set PC if tgetstr returned non-null. Saber caught this.
1733 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1735 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
1736 stuff for config manual) here where it counts; updated
1737 to use new subdir structure (gdb/doc/).
1739 * Makefile: generated from above via
1743 * gdbint.texinfo: added instructions on generating gdb.info* files
1744 locally for release. These are ordinary info
1745 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
1746 Makefile)---but due to use of texinfo 2, can't count on makeinfo
1747 to generate these, so we distribute them already formatted.
1749 * gdb.texinfo: included full Info node and menu crud (as generated
1750 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
1752 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
1753 put in comments-for-future gdb.info target (one day makeinfo will
1756 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1758 * gdb.texinfo: Updated to include new or old undocumented
1759 commands, at least the following (perhaps some others I forgot to
1760 record): info f, info float, info path, info program, info s, info
1761 set, info source, info terminal, info types, info user, set/show
1763 Also covered all recent GDB command renames for v4.
1765 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1767 * mipsread.c: Rather than keeping count of how many symtabs
1768 and psymtabs we have, for sorting purposes, count them when
1769 we need to sort. This fixes bug in rereading of symbol tables.
1771 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1773 * infcmd.c: renamed "info path" to "show paths"
1774 * gdbrc.tex: documented above.

1784 Fix up "saber_gdb" to work again.
1785 * saber.suppress: Update.
1787 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
1788 symtab.h, target.c, target.h: Lint.
1789 * core.c: setup and select frame after reading shared libs,
1790 else reading shared libs will clobber them. Lint.
1791 * utils.c (error): Force out any buffered wrap text.
1793 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1795 * remote.c: Remove decls of memory_insert_breakpoint
1796 and memory_remove_breakpoint, no longer used. (Suggestion of
1799 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
1800 to make it easier to interface to "configure"'d libraries.
1802 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
1804 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
1805 aliases for set/show print.

1861 * coffread.c [TDESC]: Move setting of debug_info from
1862 coff_symfile_read to find_linenos and make it work with BFD.
1864 * cplus-dem.c [__STDC__]: Make x{m,re}alloc return void*.
1866 * signame.c: Cast const char* to char* when assigning to sys_siglist.
1868 * utils.c (strsave): Make arg const char* not char*.
1870 * infrun.c (wait_for_inferior) [SHIFT_INSN_REGS]: Use

1894 * infptrace.c (PT_WRITE_D, PT_READ_D): Use correct values.
1895 (This still doesn't seem to make MIPS bkpts work.)

1902 * valprint.c (type_print_varspec_suffix): Wrap "ptype" output of
1903 enums appropriately.
1905 Wed May 1 14:10:22 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
1907 * signame.c: Include defs.h and param.h.
1909 * cplus-dem.c: Include defs.h and param.h.
1910 Makefile.dist: Don't hack in the "param.h".
1911 param.h: Don't include defs.h.
1913 * expread.y: Use a union to deal with the fact that type_stack
1914 can have both ints and enum type_pieces in it.
1915 ({push,pop}_type_int): New functions.
1917 Tue Apr 30 13:18:58 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

1929 symtab.c, cplus-dem.c, value.h, expread.y, valprint.c,
1930 copying.awk, solib.c, inflow.c, symmisc.c
1931 : Lint. Use read_memory not read_memory_integer on CORE_ADDR's.
1932 Use {value_as,unpack}_pointer (added to values.c)
1933 not {value_as,unpack}_long on CORE_ADDR's.
1934 Use longest_to_int (added to defs.h) instead of cast to int.
1935 Remove from_tty arg to mod_path.
1936 Put symfile_bfd in {coff,dbx}read.c not symfile.h.
1937 Use OP_NULL instead of 0 where dummy enum exp_opcode needed.

1975 * xm-tahoe.h: Remove USE_OLD_TTY (not needed now that terminal.h
1976 includes sgtty.h before sys/ioctl.h).

2410 (set_section_command): New command ("section xxx yyy" -- should
2411 be renamed to "set section xxx yyy" FIXME) which sets the

2442 * inflow.c (kill_command): After killing inferior, print our
2443 current frame in the core file, if we have one.
2444 (generic_mourn_inferior): When inferior dies, either select
2445 the current frame (in the new target, e.g. core file), or
2446 set both the current and selected frames to NULL.
2448 Changes from Peter Schauer.
2450 * infptrace.c: Avoid <sys/ptrace.h> on USG.
2452 * Make all file names fit in 14 characters (sigh and damn!):

2463 * Makefile.dist, README, config.gdb, convex-pinsn.c,
2464 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
2465 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
2468 * command.c (user_info_1, user_info): New command for listing
2469 the user-defined commands.
2471 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2473 * dbxread.c (really_free_pendings): Clear file_symbols
2474 and global_symbols after freeing them; otherwise, running
2475 this function twice (if it appears twice on the cleanup
2476 chain), we try to free things twice.
2478 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
2479 based on text_addr (the address of text in core), not on addr (the
2480 offset between text in the .o file and in core). This change
2481 is from Peter Schauer.
2483 * main.c: Define ALL_CLEANUPS as a cast of zero.
2484 (return_to_top_level): Use it.
2485 (main): Do all cleanups after each command run as part
2486 of the gdb startup sequence. Also do all cleanups before
2487 entering the command loop, and every time we exit the command
2488 loop and reenter. Before, the cleanups from the startup sequence
2489 were being left undone until the first error!
2490 (command_loop): Rename do_nothing cleanup to command_loop_marker
2491 so we can see it easily when examining the cleanup chain.
2492 (init_signals): Add another do_nothing for signal handling.
2493 (quit_command): Only try to kill target if it has execution.
2494 Problems in the target stack got us into a state where
2495 inferior_pid was nonzero but none of the targets had execution.
2496 In this state you couldn't exit gdb.
2498 * dbxread.c: Two changes from Peter Schauer.
2499 (echo_command): Fflush output after an echo command.
2500 (show_history): Pass all args to cmd_show_list.
2502 * utils.c (init_malloc): Call mtrace to turn on tracing
2503 if the environment variable MALLOC_TRACE is set to a file name.
2504 * mtrace.c: Add source file which provides a log of every malloc,
2505 free, and realloc to a trace file.
2506 * mtrace.awk: Add source file which analyzes the trace file.
2507 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
2508 (VERSION): Roll to 3.94.3.
2510 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
2511 (check_duplicates): Don't bother with watchpoints.
2512 (set_raw_breakpoint): Comment about danger of this routine.
2513 (watch_command): Parse and eval all args before calling
2516 * solib.c (find_solib): Avoid error in referencing memory to
2517 see if any more shared libraries have been added. This is
2518 particularly useful if the target has terminated. Bug reported
2521 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
2522 in bringing up 3.94.2 on the Sun-3.
2524 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
2525 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
2526 expression (in scope) before reenabling watchpoint.
2527 * signame.c (init_sigs): Add missing declaration of i, fix
2528 sys_siglist declaration.
2529 * source.c (list_command): Fixed range computation to use
2531 * stack.c (backtrace_command): Do not allow command if target has
2532 no stack, print informative error message.
2533 * target.c (target_command): Do not write into command line
2534 because this fails if the target command is used in a user defined
2535 command. [This change was enhanced by gnu to support any-
2536 unique-prefix matching on target names.]
2537 * valops.c (value_struct_elt): Avoid infinite loop on an
2538 erroneous attempt to print the member of function (try p main.p).
2540 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2542 * expread.y (name_no_typename): Avoid reduce/reduce errors
2543 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
2544 Since the GDB parser really doesn't use name_no_typename in a
2545 name-only context, the parser can't tell the diff between
2546 names and numbers here. Avoid allowing a name_no_typename
2547 to be a NAME_OR_*INT to resolve the conflict.
2549 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2551 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
2553 * valprint.c (val_print_fields): bitfield printing didn't handle
2554 byte order. Indirect through a few more fns to cope.
2556 * values.c (modify_field): also cope with byte order.
2558 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2560 Cleanup for release 3.94.2:
2562 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
2563 include files. Roll version to 3.94.2.
2565 * coffread.c (init_stringtab): Read length into unsigned char
2566 array before swapping; don't assume 32-bit longs.
2568 * target.c (target_info): Don't bother with get_sym_file, just use
2569 the symfile global variable.
2570 * symtab.h, symfile.c (get_sym_file): Delete it.
2572 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
2573 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
2574 (read_type): Replace one more error() with complain().
2576 * mipsread.c (parse_partial_symbols): Replace printf with complain.
2578 * i960-tdep.c: Fix copyright attribution.
2580 * config.gdb: Quote all backquotes in doublequotes. You can
2581 quote me on that. BSD 4.4 shell found this one.
2583 * infptrace.c (throughout): The third argument to ptrace is an
2586 * infrun.c (wait_for_inferior): When program has terminated, we
2587 have to call target_terminal_ours before we pop that target off
2588 the stack (e.g. before a call to target_kill or
2589 target_mourn_inferior). This fixes problem where a program
2590 terminates, then GDB stops for (tty output) and you have to type
2591 "fg" to the shell to resume it. FIXME: This code for what to
2592 do after termination really should be in normal_stop instead.
2594 * gdbcore.h (read_memory_check): Change declaration; it changed
2597 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
2598 4.4 prereleases, this avoids a bug in their sgtty compatability
2600 * remote.c: Use terminal.h rather than hand-rolling the same.
2602 * signame.c, signame.h (psignal): Arg is unsigned, not int.
2603 * utils.c (strsave, strstr): Fix arg types.
2604 * valprint.c (val_print): lint
2606 MIPS symbol table support from Per Bothner:
2608 * symfile.c (symtab_fns): Remove initializer table that needs to
2609 be hacked for each new symbol file format supported.
2610 (add_symtab_fns): New function, chains symbol table
2611 handlers into the global list.
2612 (symfile_init): Search this list.
2613 * symfile.h: Add next pointer, declare add_symtab_fns.
2614 * coffread.c (_initialize_coffread): Call add_symtab_fns.
2615 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
2617 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
2618 symbol *). Thus, we no longer need the hack to trash
2619 pst->filename. Good, since that hack confused code in symfile.c!
2621 (reorder_symtabs, destroy_all_symtabs): Removed static
2622 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
2623 Instead, the latter now uses a temporary array (stack-allocated
2624 from an obstack, and then freed).
2626 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
2627 haven't been set in the outermost stBlock of a procedure. This was
2628 a problem with f77 binaries on Ultrix 4.?.
2630 (new_symtab, new_symbol, new_type): Continue changing code to use
2631 obstacks more and otherwise conform to dbxread internal style.
2632 Made the free_code of symtabs be free_linetable (as in dbxread)
2633 instead of free_contents. This implies memory leaks when reading
2634 a new symbol table, until the conversion is finished. Did change
2635 (struct symbol) and (struct type) to be allocated on the
2636 symbol_obstack. Blocks and blockvectors are among the things
2639 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
2640 tested much, but it solved one problem (reported by Meissner), and
2641 cleans up some other things. The problem happened when an
2642 included file contains actual code (functions) and not just
2643 definitions. The mips coff is a little inconvenient there, since
2644 it may cause a procedure to be mapped to the wrong psymtab.
2646 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
2647 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
2648 this will need work for the new core paradigm.
2650 Opcode patches from the net:
2652 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
2653 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
2654 missing altogether - they are added here. From Bruce Bauman.
2655 * mips-opcode.h: The low mask for C0 instructions was too small.
2656 From Garrett Lau. I modified the fix to check the entire 32-bit
2659 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
2662 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2664 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
2666 * dbxread.c (read_type): Pointer subtraction (value_sub in
2667 valarith.c) sometimes failed because the types of the
2668 pointers being subtracted were not identical.
2669 These differed because dbxread.c was allocating pointer types
2670 using dbx_alloc_type+smash_to_pointer_type instead of
2671 lookup_pointer_type. I failed to find a justification for the
2672 former, so I changed it to use the latter. Similarly, I
2673 replaced smash_to_function_type by lookup_function_type,
2674 and smash_to_reference_type by lookup_reference_type.
2676 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
2677 _initialize_mipsread): corresponding changes.
2679 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
2681 * source.c (mod_path): Do tilde_expand on each component of the path,
2682 rather than on the (list of) paths as a whole.
2683 (print_source_lines): Set first_line_listed in addition to
2684 current_source_symtab and current_source_line. If the source was
2685 not findable, after a "dir" command to fix the problem,
2686 a "list" would get the wrong lines.
2688 While I was there... (gnu):
2690 * dbxread.c (read_type): Change error to complaint.
2692 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2694 First attempt at detailed understanding of symbol table memory alloc.
2696 * dbxread.c (dbx_symfile_read): Free our string table if we
2697 aren't the mainline. Free the "info" struct since we're done with
2699 (init_psymbol_list): Free any previously allocated psymbol lists.
2700 (): FIXME: Should realloc-down the psymbol lists when done reading
2701 the main symbol file?
2703 * symmisc.c (free_symtab): Free fullname field too.
2705 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
2706 (REGISTER_ADDR): Make result type unsigned int.
2708 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
2709 define REGEX must also define REGEX1 (its dependency).
2711 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2713 * tconfig/i960: No longer works, points you at vxworks960 or
2716 * xgdb.c, XGDB-README: Remove file. Users can get the much
2718 * Makefile.dist: Remove all trace of xgdb.
2720 * breakpoint.c (breakpoint_1): Pass demangle arg to
2721 print_address_symbolic.
2722 (clear_breakpoints): Remove unused function.
2723 (breakpoint_re_set_one): Guts of breakpoint_re_set.
2724 (breakpoint_re_set): Use catch_errors to do them all anyway.
2726 * gdb-int.texinfo (Host versus Target): Add section on what is
2727 a "host" feature versus what is a "target" feature.
2729 * infcmd.c (path_command, path_info): Handle the PATH variable
2730 (object search path) as conveniently as the source search path.
2731 * environ.c (set_in_environ): Set some vars in GDB's environment,
2732 in addition to the child's. PATH, G960BASE, G960BIN for starters.
2733 * source.c (mod_path): New function, from guts of
2734 directory_command, modifies a path. Used by path_command.
2735 (directory_command): Call it.
2736 * defs.h (strsave): Declare.
2738 * utils.c (sevenbit_strings): Add new printing option.
2739 (printchar): Use it.
2740 (strsave): Provide this handy helper routine.
2741 (set_width_command): Rename set_screen_width_command.
2742 (_initialize_utils): "set screen-width" => "set width";
2743 "set screen-height" => "set height"; add sevenbit-strings.
2745 * infcmd.c (do_registers_info): Print floating point registers
2746 in raw hex as well as float format, regardless of whether it is
2747 a "virtual" convertible register.
2748 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
2749 regs as a double, just in case it's being used that way.
2750 * values.c (unpack_long): Comment on array/function coercion.
2751 (unpack_double): Argument is in target byte order now. For
2752 integer arguments, just call unpack_long and float the result.
2753 * m68k-tdep.c: include defs.h for "const" handling.
2754 * remote-nindy.c: Use ieee-float stuff.
2755 (nindy_fetch_registers): Unpack double regs to host double, then
2757 (nindy_store_registers): Pack extendeds to host double, flip
2758 around by misusing unpack_double, send as target double.
2760 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
2761 zero, as when stopped at the first instruction of a process.
2763 * blockframe.c: Fix filename in comment (param.h => tm.h).
2764 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
2765 * tm-68k.h: Fix typos.
2767 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
2769 Changes from a bringup on the DEC Vax under Ultrix 4.0.
2771 * coredep.c (fetch_core_registers): Pass end-address of register
2772 section to register_addr as expected. Don't call supply_register
2773 if we'd just pass it garbage.
2775 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
2777 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
2779 * target.c (push_target, target_info): Cast enums to int for < or
2782 * stack.c (print_frame_info): Identify source file & line
2783 even if we can't print it.
2785 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
2787 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
2789 Clean up IEEE floating point support.
2791 * ieee-float.h: New file.
2792 * ieee-float.c: Write real routines to convert between host
2793 doubles and various target IEEE extendeds.
2794 * m68k-xdep.c: Eliminate assembler code for extended floats.
2795 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
2796 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
2797 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
2798 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
2799 double_to_ieee_extended.
2800 * i960-tdep.c: Define ext_format_i960.
2801 * m68k-tdep.c: Define ext_format_68881.
2802 * sparc-tdep.c: Define ext_format_sparc, though unused.
2803 * Makefile.dist (HFILES): Add ieee-float.h.
2804 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
2807 Obsolete the "coffstrip" program in favor of using BFD's strip.
2809 * nindy-share/coffstrip.c: Remove file.
2810 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
2811 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
2812 * tconfig/nindy960: Remove reference to coffstrip.o.
2814 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
2816 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2818 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
2819 * dbxread.c: Remove static symfile_bfd.
2820 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
2822 * inftarg.c (child_detach): Pop the child_ops vector if the
2823 detach is successful.
2824 * remote-nindy.c (nindy_create_inferior): Don't push a new
2825 nindy_ops since nindy uses the same one for execution and memory
2827 * core.c (core_ops): Use child_attach and child_create_inferior
2828 rather than default attach and create_inferior functions.
2830 Handle floating point registers in core files.
2832 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
2833 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
2834 This version untested since BFD doesn't yet support sun3 core
2836 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
2837 conventions. Fix comments and style. This version has not
2838 been compiled yet, since we have no HP inhouse.
2839 * core.c (get_core_registers): Look for two sections, ".reg"
2840 and ".reg2", and pass both to fetch_core_registers sequentially.
2842 Revise directory path yet again.
2844 * source.c (forget_cached_source_info): Not static any more.
2845 (init_source_path): New default source path is "$cdir:$cwd".
2846 (dir_command): Handle variable arguments ($cdir, $cwd).
2847 (source_info): Print "Compilation directory" rather than
2848 "Originally compiled in" to remind people of $cdir.
2849 (openp): If the path contains $cwd, use current directory.
2850 (open_source_file): If compilation directory is known, replace
2851 first $cdir in path with the compilation directory.
2852 (print_source_lines): Even if we can't print the lines, set the
2853 current symtab and line for future commands like "info source" or
2854 "breakpoint". Also, error message now contains the file name,
2855 line number, and file access error message.
2856 (_initialize_source): Fix help text to describe changes.
2857 * main.c (cd_command): Forget cached source info when we chdir.
2858 * utils.c (strstr): Add simple implementation.
2860 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
2862 * coffread.c (read_one_sym, init_linetable, init_stringtab):
2863 Byte-swap COFF symbol tables if necessary when reading them in.
2864 Use complain() to replace error message in one spot. Needs
2865 corresponding change in bfd/coff-code.h to make some symbol
2866 swapping routines non-static.
2868 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
2870 Merge changes from Eirik Fuller, for UTek.
2872 * defs.h (errno): Add declaration.
2873 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
2874 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
2875 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
2876 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
2877 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
2878 declarations of errno.
2880 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
2882 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
2883 <rpc/rpc.h> and <rpc/types.h>.
2885 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
2887 * i960-tdep.c (examine_prologue): Add new argument limit,
2888 which stops the scan at the end of the prologue, or at the PC.
2889 This fixes a problem where it walks down into the code for the
2890 user's statements if that code looks like function prologues.
2891 Mark Fox and I have been bouncing this code back and forth, making
2892 small changes to it. Callers changed to match.
2894 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
2896 Cleanup for gdb-3.94 release final:
2898 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
2899 the .c files from vx-share and nindy-share, from the various
2900 macros, since they are not found via ALLDEPFILES.
2901 (SFILES): Add tm-i960.h.
2902 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
2903 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
2905 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
2906 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
2908 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
2910 * am29k-tdep.c: Add contribution line.
2911 (examine_prologue): Cache information about function prologues in
2912 the misc-function-vector to avoid lots of references over the
2913 serial line while examining instructions.
2915 * core.c (core_close): New function made from cleanup_core.
2917 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2918 remote-vx.c, remote.c, target.c, target.h,
2919 Update target_ops vector to add attach, close, and load entries.
2920 Use add_syms_addr_command, not add_file_addr_command, for
2921 add_file. Break out close routine from existing code.
2923 * dbxread.c (really_free_pendings): Don't free pending_blocks;
2924 they are in an obstack.
2925 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
2927 (define_symbol): Add symbol type parameter; change callers;
2928 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
2929 it to influence the symbol class on the i960.
2930 (define_symbol): Swap LOC_CONST's into target byte order.
2932 * exec.c (exec_close): New function.
2933 (exec_file_command): Call it.
2935 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
2936 Fix byte order of frame pointer.
2937 (read_var_value): Result of 0 if var's value can't be found,
2938 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
2939 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
2940 (locate_var_value): Use read_var_value and use its lazy address
2941 as the location of the var's value. Lint.
2943 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
2946 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
2947 obsolete Intel versions in favor of vxgdb versions.
2948 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
2949 code dealing with byte order of values, which Intel did in host byte
2950 order rather than gdb-4's target byte order.
2951 (i960_frame_chain_valid): Move to nindy-tdep.c.
2952 (examine_prologue, skip_prologue, frame_find_saved_regs,
2953 frame_args_address, leafproc_return, saved_pc_after_call,
2954 pop_frame): Add vxgdb versions from Mark Fox.
2955 (examine_prologue, frame_struct_result_address): Add code
2956 to deal with the saved value of G13 (struct return address
2958 (frame_args_address): Modify Mark's version to prefer the
2959 saved value over the current value in the topmost frame.
2960 Cache result in the frame info to avoid performance hair in
2962 (print_fault): Add gdb960 code for printing faults.
2963 (_initialize_i960): Actually call check_host.
2965 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
2966 add stub routines. FIXME, these currently just return zero!
2968 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
2969 (attach_command): Call target_attach, not target_open, now.
2971 * infrun.c (normal_stop): Make global, not static, for vx_attach.
2972 (child_attach): Rename from child_open.
2973 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
2974 don't confuse it with a zero step_resume_break_address.
2976 * inftarg.c (child_detach): Eliminate inferior_pid test.
2977 (child_files_info): Clean up message a bit.
2978 (child_ops): Use child_attach, not child_open, to attach.
2980 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
2981 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
2982 findvar.c to here, since it depends on the contents of the
2983 shadow_contents of breakpoints, but keep if #if 0 since it is
2986 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
2989 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
2990 (ptype_command, display_command): Eliminate have_inferior_p and
2991 have_core_file_p in favor of target_has_stack or
2992 target_has_execution.
2993 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
2994 code for actually finding the values of arguments, though we still
2995 keep track of the maximum stack offset for use in printing unnamed
2996 arguments. Handle missing FRAME_ARGS_ADDRESS.
2998 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
2999 (struct nindy_regs): Define registers passed to/from nindy.
3000 (nindy_fetch_registers, nindy_store-registers): Translate between
3001 nindy and GDB formats for the registers.
3002 (dcache_init): Statically allocate the cache, since it was being
3003 allocated by a malloc that was never freed anyway.
3004 (nindy_create_inferior): Error, not core dump, if no exec file.
3005 (nindy_before_main_loop): Use target_load, not target_add_file.
3007 * remote-vx.c (net_load): Specify large timeout for load
3008 requests. Allow user to break out with INTERRUPT.
3009 (net_break): Remove useless code, clean up. Change callers.
3010 (parse-args, skip_white_space, find_white_space): Clean up arg
3011 parsing to cope with quoted strings.
3012 (net_wait, net_quit): Never call error, just return status.
3013 (vx_read_register, vx_write_register): Cleanup status checking.
3014 #ifdef the code based on which CPU we are using (960 or 68k),
3015 FIXME, this should be completely general but it isn't yet.
3016 (vx_xfer_memory, vx_resume): Cleanup status checking.
3017 (vx_run_files_info): Improve message.
3018 (vx_load_command): Renamed from vx_add_file_command. Allow load
3020 (net_ptrace): Remove unused routine.
3021 (vx_wait): Adopt code from vxgdb960 to cope with broken
3022 connections to target machine and prompt to disconnect. Remove
3023 debug printouts. Map some EVENT_'s to SIGnals.
3024 (add_symbol_stub, vx_open): Print names of object files we found,
3025 and "ok" if we read their symbols OK. Clarify output in general.
3026 (vx_attach, vx_detach, vx_kill): Add these commands.
3027 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3028 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3029 "info files" output, and create_inferior, since we already have
3032 * stack.c (frame_info): Replace Frame_unknown with 0.
3033 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3034 (return_command): Pop until the PC matches as well as the FP,
3035 so it works even if the FP is shared with another function,
3036 as in "frameless" or "leaf" procedures.
3038 * symfile.c (load_command): renamed from add_file_target_command.
3039 (add_syms_addr_command): renamed from add_file_addr_command.
3040 (add_syms_command): Stub to call target_add_syms.
3041 (_initialize_symfile): Change command names and descriptions,
3042 add-file => add-syms, and load from alias to its own command.
3044 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3045 maybe_kill_then_create_inferior): Default for attempts to start
3046 a process, if one is already running, is to ask about killing
3047 it and retry if yes.
3048 (upstack_create_inferior): #if-0 it, strata obsolete it.
3049 (push_target, unpush_target, pop_target): to_close() a target
3050 before unstacking it.
3051 (target_info): Renamed from target_files_info.
3052 (_initialize_targets): Rename "i files" as "i target", accessible
3055 * target.h: Improve comments about the target_ vectored routines.
3057 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3058 Convert commenting style to standard GNU style.
3059 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3060 (SKIP_PROLOGUE): No longer a no-op.
3061 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3062 (*_REGNUM): Sort register numbers.
3063 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3064 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3065 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3066 are now 10 byte extendeds, not 8 byte doubles.
3067 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3068 for nindy versus vxworks targets. FIXME, this should possibly go
3069 in the target vector.
3070 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3071 frame_saved_regs and arg pointer with each frame.
3072 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3073 (FRAME_ARGS_ADDRESS): Use cached result.
3074 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3075 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3076 (PRINT_RAMDON_SIGNAL): Call print_fault.
3077 (POP_FRAME): Now works.
3079 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3080 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3081 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3082 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3085 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3086 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3088 * valarith.c (value_subscripted_rvalue): Avoid handling
3089 floats and doubles specially; it gave alignment errors. Lint.
3091 * valops.c (value_of_variable, value_of_this): Error if unknown
3094 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3095 to avoid alignment problems.
3096 (value_print): Handle unknown value address.
3097 (cplus_val_print): Two args are ignored; remove them. Change caller.
3098 (val_print): Use unpack_long rather than pointer-deref.
3101 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3102 to avoid alignment problems.
3103 (value_being_returned): Error if return value unknown.
3104 (set_return_value): Add bogosity warning, FIXME. *
3106 * TODO: A woman's work is never done.
3108 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3109 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3110 Add ieee-float.o to OBS.
3111 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3112 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3113 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3115 Changes to generalize the VxWorks RPC protocol slightly, to handle
3116 i960 as well as 68000.
3118 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3119 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3120 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3121 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3122 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3123 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3124 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3125 so they will move in target byte order rather than network
3126 byte order (happens to be the same).
3128 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3130 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3132 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3135 Add contribution lines to various files, showing where they
3138 * breakpoint.c (break_insn, check_break_insn_size,
3139 read_memory_nobpt): Remove to mem-break.c.
3141 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3144 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3145 entry has bad register number. This change is not
3146 tested in this release, FIXME.
3148 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3151 * value.h: Force value's contents field to be aligned to hold
3152 at least a double or a long long (if supported). This avoids
3153 doing bcopy's in and out of the contents field.
3155 (step_1): Avoid coredump under obscure circumstances when we
3158 * symtab.h (misc_info): Add field to misc function vector for
3159 any kind of cached information the target code desires. AMD
3160 29000 uses this to avoid repeating examine_function_prologue's.
3162 * coffread.c: Lint. Remove static symfile, read_section_header.
3163 core.c (have_core_file_p): Lint: remove.
3164 expprint.c (print_subexp): Lint.
3165 infptrace.c, valops.c, valprint.c: lint.
3167 Roll in changes from vxgdb-5.0.1:
3169 * symtab.h: Comment byte order of each address class. Add
3170 LOC_LOCAL_ARG for frame-relative args (960).
3171 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3172 symtab.c, symmisc.c: ditto.
3174 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3176 * remote.c (remote_resume): Error if resume with a signal.
3178 * symfile.c (prim_record_misc_function): Clear misc_info.
3179 (fill_in_vptr_fieldno): Check stub type of arg.
3181 * valops.c (value_cast): Avoid looking up names of types whose
3182 name we don't know, to prevent coredump. Sun CC produces typedef
3183 rtx and the name of *rtx is zero...
3185 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3187 Roll in changes from final AMD 29000 port (Tiemann).
3189 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3190 for ../include/a.out.encap.h. This might not work now that BFD
3191 is separately compiled. Instead, BFD support for encap will have
3192 to translate machine type 29k into the right COFF_MAGIC.
3194 * infcmd.c: Remove references to inferior_pid that aren't used
3195 in actual ptrace calls; use target_has_execution, etc.
3196 (have_inferior_p): Remove function.
3197 (program_info): Print target info rather than "process number";
3198 avoid gratuitous messages unless from_tty.
3199 (run_stack_dummy, finish_command): Set proceed_to_finish.
3200 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3201 main.c: Lint. Lose have_inferior_p().
3202 inferior.h (have_inferior_p): Remove, lint.
3203 (proceed_to_finish): Add flag to ask that all regs be saved
3204 by normal_stop, for the few commands that need it, speeding up
3205 serial I/O. Add comments to stop_registers.
3207 * remote-eb.c: Remove newline from breakpoint message we grep
3208 for. Never time out when running the user program.
3212 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3214 Roll in changes from vxgdb-5.0.1:
3216 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3217 symbol in its raw form, we are processing an unlinked ".o" file.
3218 See if the target environment has assigned it an address, using
3219 target_lookup_symbol (VxWorks does), and enter it into the symtab
3222 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3223 68k versions for a simpler version that assumes zero FP at bottom.
3224 Fixes bug of truncated stack reports.
3226 * target.h (target_lookup_symbol): Define this routine's args
3227 and result, finally.
3229 * target.c (nosymbol): Default routine for target_lookup_symbol.
3230 (target_default): Default lookup_symbol and call_function too.
3231 (files_info): Only print has_all_memory warning if a non-dummy
3234 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3235 vx_convert_from_virtual): If target does not have floating point,
3236 zero register "values", and avoid doing cross-net conversions.
3237 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3238 (vx_open): Rearrange code that attaches to target and reads
3239 symbols for all loaded modules, to work if some of the modules
3240 are not accessible. Add symbol_stub() and add_symbol_stub()
3241 as callbacks from catch_errors(). Allow connect attempt to be
3242 interrupted painlessly with ^C (FIXME, there are still some bugs
3243 if the interrupt happens during symbol reading.). Print
3244 final message with puts_filtered, since symbol messages are
3249 * main.c (catch_errors): Only print errstring if non-null.
3250 (command_loop): Avoid an ioctl per command to test ISATTY.
3252 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3253 (vx_xfer_memory): Return correct result!
3254 (vx_files_info): Indicate whether target has float or not.
3255 (vx_lookup_symbol): Complain, not error, if target gone.
3256 (vx_open): Print "Connected" msg before disabling immediate-quit.
3257 [FIXME: lookup_symbol and vx_open changes need testing.]
3259 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3260 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3261 contributor lines and update copyrights to 1991.
3263 Changes from an attempted H-PUX host port:
3265 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3266 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3267 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3268 * remote-vx.c: include <sys/time.h> for HPUX.
3269 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3270 "core_file_command" routine to BFD regime. May not work yet.
3272 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3274 * xgdb.c: Replace X10 version with some VJ version.
3275 (FIXME: Its copyright assignment is not on record.)
3276 * xgdb.c: Update include files to X11R4 (Xaw crud).
3277 (xgdb_display_source, create_text_widget): fix call to
3278 get_filename_and_charpos. Rewack source window stuff for X11R4
3279 (gleaned from include files, and "nm's" of binary libraries, since
3280 I had no doc available).
3281 (append_selection, append_selection_word): Disable with FIXME
3282 since R4 changed interface here.
3283 (create_buttons): Add back the old set of buttons.
3284 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3286 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3287 Roll VERSION to 3.94 (not yet final though).
3289 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3291 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3292 obstack_int_grow, obstack_int_grow_fast): Eliminate
3293 cast on left of assignment, which gives MIPS cc fits and is
3296 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3297 F_ALIAS. Use printf, not fprintf, when not passing a file
3299 (compare_opcodes): Check that identical instructions have
3300 identical opcodes, complain otherwise.
3302 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3303 was reported by Roland McGrath.
3304 (unimp): Only match if exactly zero instruction. (Roland)
3305 (branches and traps): Generate all variations of these
3306 instructions with macros, based on a single call that defines
3307 each condition name and its binary representation.
3308 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3310 * valprint.c (val_print_fields): Take, and use, format parameter.
3311 This means that "p/x struct" again prints the elements in the
3312 desired format. Changed callers.
3314 * stack.c (frame_info): Use filtered output, and indicate wrap
3315 points. Remove kludgy formatting designed to avoid line wrap.
3317 * utils.c (wrap_here): If the line is already full (because
3318 we had printed a long indent or long wrapped string), do an
3319 immediate newline-and-indent.
3321 * m68k-pinsn.c (print_insn_arg): Bugfix from
3322 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3323 instruction is incorrectly disassembled as bkpt #8.
3325 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3326 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3327 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3328 and then will dump core (sometimes). I traced it back to an
3329 uninitialized symfile_name in psymtab_to_symtab.
3330 (const_vol_complaint): Add quotes to message.
3331 (define_symbol): Only believe line number if gcc_compiled.
3332 Avoid allocating symbol if we will not return it.
3334 Add target strata support so that newly established targets go
3335 into their right place in the target stack (e.g. a new exec file
3336 doesn't wipe out the ability to access the running process).
3338 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3339 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3340 and initialize it properly in all the targets.
3342 * target.h: Document strata. Change return type of push_target.
3344 * target.c (nomemory): new function for dummy memory access.
3345 (tcomplain): Rename complain, now also used in symfile.c.
3346 (push_target): Push targets within strata. New return value shows
3347 whether new target is on top of stack or not. Always keep dummy
3349 (target_files_info): Ignore dummy target.
3351 * core.c (core_open): Warn user, and skip accessing file, if the
3352 core target is not the topmost target in the stack.
3353 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3356 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3357 target_ops, it doesn't belong there since we have no regs there.
3358 Change name of target from machine => memory to clarify.
3360 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3362 * Freeze version 3.93 for release.
3364 * Makefile.dist: Handle vx-share and nindy-share subdirs
3365 properly when building gdb.tar.Z.
3367 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3368 printed in various places, so I could change just one copy.
3370 * dbxread.c, coffread.c: Change references to bfd->iostream
3371 to cast to FILE *, now that BFD avoids needing types defined
3372 in other header files.
3374 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3376 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3377 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3378 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3379 (actually gcc -Wall).
3381 * dbxread.c: Remove first_global_sym, last_global_sym, since
3382 they are never referenced.
3384 * defs.h (baud_rate): Declare.
3385 main.c: Define it, and add the -b option to set it.
3387 * gdb-int.texinfo: Add text on how to define a new host or target
3388 architecture, prompted by Per Bothner's questions about MIPS
3391 * gdb.texinfo: Document "complaints". Change doc of -q since
3392 gdb no longer prints the copyright and blurb if you specify a file
3393 name to be debugged (just like Emacs). Add doc for Nindy-specific
3394 command line flags for specifying target serial port and such.
3395 Update copyright to 1991.
3397 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3398 has taken over for us the job of ripping up executable files. The
3399 crud caused Per Bothner's port to not compile.
3401 * infrun.c (normal_stop): Avoid printing "Program exited
3402 normally" if we are in batch mode. This allows a GDB which
3403 executes a program on a target system, to behave like a Unix
3404 command (input from stdin, output to stdout, no extraneous
3407 * main.c (main): Allow additional machine-dependent command line
3408 options to be specified with the ADDITIONAL_OPTIONS,
3409 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3410 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3411 processing to occur just before the main loop with
3412 BEFORE_MAIN_LOOP_HOOK.
3413 (main): If a "core file" argument is specified, and it is not a
3414 core file, try it as a process ID to attach.
3415 (symbol_completion_function): Attempt to cope with
3416 "show screen-" TAB, not very successfully. This needs more work,
3418 (batch_file): New function, returns whether we are reading
3419 commands from an interactive tty on stdin, or from somewhere else.
3420 Called by normal_stop since it doesn't get from_tty passed down
3421 to it like many commands do.
3423 * remote-nindy.c: Handle command line options for nindy
3425 (nindy_before_main_loop): Prompt user for tty name if they
3426 don't specify it before getting to the interactive command loop.
3428 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3429 and -r command line options. Also add hook before main loop
3430 to make it easy to specify a tty.
3432 * TODO: More things to do, one done.
3434 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3436 * dbxread.c: Make complaint() calls pass pointer, not struct.
3437 Add complaints about badly formatted C++ type information
3438 (const/volatile indicator, and parse errors resulting in
3439 error_type). Fix C++ virtual member fn comment.
3440 (read_struct_type): Avoid bumping pointer if we got a parse
3441 error; this prevents our walking beyond the end of a string.
3442 Terminate loop on null char as well as semicolon.
3443 (process_one_symbol): Fix the LBRAC fix so that it uses the
3444 last previous SLINE, FUN, or SO record's PC address. C++ debug
3445 symbols did not have SLINE records in a useful order compared
3446 to the LBRAC records.
3447 (define_symbol): Handle "catch" records.
3449 * symtab.c (check_stub_type): Added new complain
3450 `stub_noname_complain' and added a consistency check to
3451 keep the debugger from crashing when finishing from an
3452 exception frame. A real fix will be needed later.
3454 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3456 * infcmd.c (attach_command): Make global.
3458 * Makefile.dist (REMOTE_OBS): Make these compile by default,
3459 but make them easy to comment out. Perhaps later they should
3460 be enabled by what CPU you configure for? FIXME.
3461 (VERSION): Roll to 3.93.
3462 (pinsn.o): Remove rule for obsolete file.
3463 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
3465 Run down a problem that manifested by printing the wrong function
3466 name in stack traces of read_ofile_symtab. Turned out that the
3467 problem was the SunOS 4.1.1 (and previous) C compiler outputs
3468 the LBRAC symbol with an address in the *data* segment, which
3469 blew our binary search through the blocks.
3471 * dbxread.c: Use the complain() facility consistently to bitch
3472 about problems in the symbol file we are reading.
3473 (finish_block): Add code to check the nesting of the blocks;
3474 complain and Procrust them to fit if wrong.
3475 (make_blockvector): Check the order of the blocks, complain
3476 [but don't cope] if wrong.
3477 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
3478 symbols to be sure their PC value is greater than the last SLINE
3479 (line number) symbol we've seen, complaining and adopting the
3480 SLINE PC value if wrong.
3482 * symfile.h (struct complaint, complaint_root, complain,
3483 clear_complaints): Add.
3484 * symfile.c (complain, complaint_root, clear_complaints): Add
3485 facility to deal with non-fatal complaints and to regularize their
3487 (symbol_file_add): Clear complaint counters to allow new complaints.
3488 (initialize_symfile): Add 'set complaints' and 'show complaints'.
3490 * dbxread.c (dbx_symfile_read): Remember the address and size
3491 of the string table for the main symbol file, so we won't read it
3493 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
3494 to avoid reading the string table yet again. Lint.
3495 (throughout): Improve filtered output, including word wrap.
3496 (read_range_type): Improve Bothner's fix to handle other types too.
3498 * utils.c: Improve line wrap implementation. Handle unlimited
3499 width by making chars_per_line unsigned.
3500 (puts_filtered): New, easy, function.
3502 * defs.h (puts_filtered): add.
3504 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
3505 call the identical sort_symtab_syms() in symfile.c instead.
3507 * expread.y: Suggest the `file' command rather than `symbol-file'.
3509 * command.h (enum var_types): Add zinteger for seroable
3511 * command.c (do_setshow_command): Handle var_zinteger. Restructure
3512 nested if's into a switch.
3514 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
3515 we did not stop because of a breakpoint (it must have been for
3516 some other reason, like a "stepi"), so don't print anything.
3518 * symtab.c: Include <sys/types.h> all the time. Now that BFD
3519 doesn't include <sys/types.h>, old SunOS's require it for
3522 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
3524 A test port of gdb-3.92.6 to the Sony NEWS.
3527 Don't normally link in remote- or vx stuff.
3528 Some of it doesn't compile, and it wastes space for 99% of the users.
3529 Remove reference to no-longer-used HAVE_VPRINTF.
3530 Fixed BFD_DEP typo to BFD_DIR.
3532 Fix cast in arg to bfd_h_getlong.
3533 Make char *prefix be const.
3534 Fix how certain range types are mapped into builtin unsigned int types.
3536 Remove 2 #includes. They cause errors (on Sony, at least),
3537 and aren't needed (they wern't in earlier versions).
3539 print_address_symbolic should never demangle labels
3540 (since it prints *assembler-level* labels).
3542 [This was superseded by the change to printcmd below.]
3545 Add some "volatile" return types to avoid warnings.
3546 If MISSING_VPRINTF add vprintf function and not just macro
3547 (since vprintf is used in printcmd.c).
3549 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
3550 (The latter isn't grokked by some PCC-based compilers.)
3552 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
3554 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
3555 * nindy-share/coffstrip.c
3556 Added some forward declarations (otherwise, gcc complains
3557 about implicit extern redefined as static).
3559 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3561 Changes inspired by Per Bothner:
3562 * printcmd.c (print_address_symbolic): Take additional parameter
3563 specifying whether to demangle.
3564 (print_address): Pass in asm_demangle to control demangling.
3565 (print_address_demangle): New fn, takes explicit arg to control
3567 * utils.c: Add new vars demangle and asm_demangle, and let them
3569 (fputs_demangled): If !demangle, just print the argument.
3570 (fprint_symbol): If !demangle, just print raw symbol.
3571 * valprint.c (val_print): Call print_address_demangle rather than
3572 print_address, to cause demangling to depend on the global
3573 rather than assembler-level demangling setting.
3574 * WHATS.NEW, gdb.texinfo: Document.
3576 * main.c (show_command): Show all settings if no arg.
3577 (initialize_main): Make "info set" the same as naked "show".
3578 * command.c (cmd_show_list): Handle prefix commands in the
3579 list, and print the name of the setting as well as its English
3580 description and value.
3582 Allow gdb functions to specify where a line should wrap if it
3583 exceeds the size of a terminal line. Use it to make the output
3585 * utils.c (set_screen_width_command): New fn, mallocs a buffer
3586 of the right size when screen width changes.
3587 (set_screensize_command, screensize_info): Remove #if 0'd fns.
3588 (wrap_here): New fn, indicates a point in the output where we
3589 should wrap the line rather than just letting it overflow at a
3591 (fputs_filtered): Implement wrapping.
3592 (n_spaces): New fn, returns a pointer to N spaces.
3593 (print_spaces_filtered): Use n_spaces.
3594 * defs.h (n_spaces): Declare.
3595 * stack.c (print_frame_info): Wrap with 4-space indent after
3596 fn name and before filename and line number.
3597 * printcmd.c (print_frame_args): Wrap with 4-space indent
3598 before each argument name is printed.
3599 * valprint.c (value_print): Wrap with no indentation before
3601 (val_print_fields): Wrap with indentation relative to nesting
3602 level before each field name.
3603 (val_print): Wrap with nesting indentation before array elements.
3604 * command.c (do_setshow_command): Avoid extra newlines,
3605 wrap with 4-space indent around values printed, end with period.
3606 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
3608 * breakpoint.c (breakpoint_1): Implement addressprint for
3609 "info breakpoints" display. Change file name and line number
3610 format to " at file:nnn" rather than " (file line nnn)".
3611 * gdb.texinfo: Document.
3614 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3616 Frozen for gdb-3.92.6 release.
3618 README, WHATS.NEW: Update for 3.92.6 release.
3620 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
3621 coffread.o from configs since it is now built by default.
3622 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
3623 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
3624 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
3625 from configs since it is now built by default.
3627 Makefile.dist: Update for release 3.92.6. Handle files that
3628 have been moved to ../include, ../getopt, or ../bfd. Add
3629 saber.suppress and tests directory. Add config.status to
3630 the release (it will say "none").
3632 coredep.c: Minor formatting fixes.
3634 These changes were made in early December but only checked in now:
3635 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
3636 nindy-share/nindy.c: lint
3637 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
3638 register values coming back from the target; we store values
3639 in target byte order everywhere.
3641 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
3643 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
3645 * valprint.c (cplus_val_print, val_print_fields): New functions,
3646 which print C++ objects. They conspire to avoid printing a
3647 virtual base class more than once, following all the twists and
3648 turns of C++ virtual base rules.
3649 (val_print): Call the above rather than do it by hand.
3651 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
3652 symbol file, not for added files like shared libs. This really
3653 needs to be generalized to a timestamp per file.
3655 * core.c (cleanup_core): Avoid coredump if no core file.
3657 * config.gdb: Accept -host or -target in place of +host or
3660 * coffread.c (find_linenos): Avoid desupported BFD interface
3661 to line numbers. We still read them manually rather than using
3662 BFD's "generic" features.
3664 * gdbrc.tex, threecol.tex: Add GDB reference card and its
3666 Makefile.dist: Add refcard to OTHERS list for creating tar files.
3668 * Makefile.dist: Eliminate use of $< in explicit targets.
3670 * readline/Makefile: Use $< rather than $*.c, which does not
3671 include the VPATH in GNU Make.
3673 * tconfig/i960-bout, tconfig/i960-coff: These are identical
3674 copies of tconfig/i960, added for global configuration
3675 compatability. All i960 versions can read both coff and b.out.
3677 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
3678 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
3681 * TODO: Think of more things to do.
3683 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
3685 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
3686 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
3687 64-bit float conversion.
3689 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
3690 equivalent to sun?os4 so global config works.
3692 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
3694 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
3696 * main.c: Only declare linesize once; declare pagesize not at
3697 all, since it is never used.
3698 (main): Clear newly allocated line before it is used.
3700 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
3702 Further stabilization for the Intel 960.
3704 * Makefile.dist: Parameterize the location of the "include"
3705 and "bfd" directories, as well as "getopt". Add symfile.c.
3706 Link in both dbxread and coffread. Fix up "make depend" to
3707 rewack the locations of include, bfd, and getopt in its output.
3709 * README: Document moving include files, improve some of
3712 * coffread.c: Move common code out to symfile.c. Change
3713 symbol_file_command style interface to use new *_symfile_init
3714 and *_symfile_read interface under BFD. Use BFD internal
3715 info to locate line table, symbols, etc.
3717 * core.c (core_fetch_registers): Rename to get_core_registers
3718 to avoid confusion with fetch_core_registers.
3719 (register_addr): Move to coredep.c, which is already machine
3720 dependent. This leaves core.c pretty clean of dependencies.
3722 * coredep.c (register_addr): Accept this routine from core.c.
3724 * dbxread.c: Move common code (with coffread.c, etc) into new
3725 symfile.c. Each psymtab now contains a pointer to the
3726 format-dependent function that knows how to read it in. Make
3728 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
3729 (process_one_symbol): Add code to complain about a "compiler bug
3730 we muzzle here", if we actually see it.
3732 * eval.c (evaluate_subexp): Insert missing "break" statements
3733 in code that determines whether a variable is an lvalue in
3734 memory, register, or whatever. I detected this via a compiler
3735 bug in which it *almost* mashed out the whole switch statement.
3737 * gdb-int.texinfo: Add minor sections on configuring gdb for
3738 release, and about the README file.
3740 * infcmd.c (registers_info): Fix formatting somewhat. Still
3741 not as pretty as before, but it handles byte swapping.
3743 * remote-nindy.c: If data cache routines are interrupted while
3744 waiting for the remote end, be sure that any uninitialized cache
3745 blocks are on the free list, not on the valid list!
3747 * symfile.h: Flesh out this header file with all the various
3748 routines and variables that have been merged in from dbxread.c
3749 coffread.c, and symtab.c to symfile.c.
3751 * symfile.c: New file, containing code common to dbxread.c,
3752 coffread.c, and some code from symtab.c. All generic code for
3753 reading symbol files should be in here now.
3754 (unrecord_misc_function): Remove unused function.
3756 * symtab.h: Remove file-reading things to symfile.h.
3758 * symtab.c: Remove file-reading things to symfile.c.
3760 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
3761 to decode i960 fault types.
3763 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
3764 target.c: Change type of the "resume" function from int to void,
3765 since its result was never used.
3767 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
3769 * main.c: Replace "stupid" with "caution"; you now "set caution
3772 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
3774 * infcmd.c (do_registers_info): Call val_print to deal with the
3775 byte order of the registers being printed. FIXME, this makes
3776 the formatting of the output uglier.
3778 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
3779 defined, call it for signals the debugger doesn't itself use.
3780 The i960 uses this for more detailed fault information.
3782 * remote.c (remote_open): If arg is null, print help rather than
3785 * sparc-xdep.c (register_valid): Avoid declaring size, since
3786 various modules will think of various sizes depending on the
3787 architecture of their tm-file. FIXME, we need protection against
3788 actually entering one of those modules, which would clobber
3789 storage if not for the target architecture compiled into gdb.
3791 * stack.c (up_command, down_command): Always print the frame
3793 (up_silently_command, down_silently_command): New commands
3796 * i960-pinsn.c (reg), i960-tdep.c: Lint.
3798 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
3799 more parameters than it used to.
3801 * findvar.c (registers): Increase slop to 256 bytes, which should
3802 protect us against even most RISC machines with large register
3804 (locate_var_value): Move declaration inside related ifdef.
3806 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
3807 throughout, to avoid throwing away buffered input from the board.
3808 (nindy_wait): Supply_register takes addr_of_value, not value.
3809 (i960_print_fault): Renamed from i80960_fault.
3810 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
3811 (nindy_store_registers): Avoid regs_changed stuff, just stuff
3813 (nindy_create_inferior): Don't bother to write PC_REGNUM since
3814 we can set the PC in the call to proceed(). Unpush nindy_ops
3815 before pushing it on top, to avoid message to user. Eliminate
3816 commentary from Unix machines that just misleads here.
3817 (reset_command): Fix error message to suggest target command.
3819 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
3821 Release 3.92.5 as frozen.
3823 Stabilize the merged release...with help from lint, Saber C,
3826 Everywhere: Add include files needed to declare return types
3827 of functions called.
3829 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
3831 * breakpoint.h: Add undeclared breakpoint functions, and some
3832 functions for display handling since I couldn't think of a better
3835 * breakpoint.c (insert_breakpoints): Make code for disabling
3836 shared library bkpts more likely to work. It's used when we
3837 rerun a program and stop before the shared library has been
3839 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
3840 cast from pointer, so it squeezes through catch_errors.
3841 (bpstat_stop_status): Fix logic broken some time ago. We now
3842 always create a bpstat if the stop address matches a breakpoint,
3843 even if we don't stop there -- just like the old code used to do
3844 before I got my fingers into it (sigh).
3845 (breakpoint_1): Print "ignore count" after "stop only if"
3846 condition, since that's how it actually works.
3847 (mention): Handle watchpoints as well as breakpoints.
3848 (watch_command): use set_raw_breakpoint and mention to do most
3849 of the work (and initialize all the fields!). Only pass one
3850 arg to parse_c_expression, since that's all it takes.
3852 * command.c (not_just_help_class_command): Rename arg to args
3853 since we ignore "unused argument" warnings on vars named "args".
3854 inflow.c (child_terminal_info): ditto.
3855 infptrace.c (kill_inferior): ditto
3856 main.c (catch_errors, version_info, quit_command, pwd_command,
3857 source_command, dump_me_command, editing_info,
3858 set_history_size_command, set_history, show_history,
3860 stack.c (locals_info): ditto
3861 target.c (target_files_info): ditto
3862 valprint.c (set_input_radix, set_output_radix): ditto
3864 * core.c: Remove old variables for handling core and exec file
3865 sections (data_start, data_end, stack_start, stack_end,
3866 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
3867 text_end, exec_data_start, exec_data_end, text_offset,
3868 exec_data_offset, data_offset, stack_offset). They're
3869 superseded the more general build_section_table and
3871 (get_exec_file): Mention the `file' command.
3872 (read_memory_check): Rename to memory_error, and only call it
3873 in the case of an actual error.
3874 (read_memory, write_memory): call memory_error.
3875 (core_fetch_registers): Register section name is ".reg".
3877 coredep.c: Remove a bunch of crud now that all this file does
3878 is pull the registers out of a core file.
3879 (fetch_core_registers): Rewrite to actually work, I hope.
3881 dbxread.c: Use a.out.gnu.h, not system a.out, now.
3882 Replace index() with strchr(). Remove all the pre-BFD macro
3883 definitions for accessing the symbol file.
3884 (struct dbx_symfile_info): Encapsulate the information that
3885 dbx_symfile_init needs to pass to dbx_symfile_read in this
3888 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
3889 dbx_symfile_discard): Rearrange symbol file reading to divide
3890 the format-specific part from the format-independent part,
3891 leaving the format-independent part such as file name expansion
3892 and opening in symtab.c. This replaces
3893 partial_symbol_file_open and partial_symbol_file_read.
3894 Symbol_file_read, add_file, add_file_target_command,
3895 add_file_addr_command move to symtab.c. Pass an explicit
3896 "mainline" flag for when reading the main symbol table, rather
3897 than relying on the offset address to be zero or nonzero.
3899 (dbx_symfile_read): Don't allow void *'s to be printed as
3901 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
3902 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
3903 macro" debug version really work.
3904 (read_dbx_symtab): Remove unref'd parameter inclink.
3905 Avoid swapping N_SLINE symbols, for speed.
3906 Merge N_TEXT!N_EXT case with the other external symbol
3907 definitions' case. Add comments.
3908 (start_psymtab): Allocate the symfile name in the psymtab on
3909 the psymbol_obstack, rather than using the caller's storage.
3910 (end_psymtab): Only allocate a dependencies list if there are
3912 (psymtab_to_symtab_2): Use BFD when reopening file to read
3913 its symbols for real.

3917 (read_range_type): Add FIXME about comparing a long to 1<<32.
3919 * coffread.c: Minor changes to move things closer to the new
3920 regime with symtab.c and dbxread.c Major work is still needed
3923 * exec.c (exec_file_command): Remove old variables (see core.c
3925 (xfer_memory): If memory transfer is right at the end of a
3926 section, don't lose.
3928 * findvar.c (get_saved_register): If value is in a real
3929 register, LVAL is lval_register, not lval_memory.
3931 frame.h: Declare print_sel_frame and record_selected_frame.
3933 gdb-int.texinfo: New file, for GDB internals documentation.
3934 Very simple, unformatted doc of cleanups is there for now.

3937 section addresses and offsets. (See core.c above.)
3938 Declare fetch_core_registers and registers_fetched.
3940 getopt.c: Declare char *alloca(); even on SPARC.
3942 infcmd.c (run_command): Call target_kill rather than
3944 (step_command, next_command, stepi_command, nexti_command):
3945 Declare from_tty parameter even though we don't use it.
3946 (run_stack_dummy): argument BUFFER is a char array, not
3947 a pointer to REGISTER_TYPE.
3948 (finish_command): using_struct_return needed a value *,
3949 not a struct symbol *.
3951 * infptrace.c (child_xfer_memory): To avoid dependency on
3952 where sections are in memory, try PT_WRITE_D and if that fails,
3953 try PT_WRITE_I. Most Unixes don't care which you use.
3955 * infrun.c (step_resume_break_shadow): Change to array to
3956 match other breakpoint shadow storage.
3957 (clear_proceed_status): Pass address of bpstat to
3958 bpstat_clear, not the bpstat itself.
3959 (child_create_inferior): FIXME comment about if the child
3961 (start_inferior): Remove old function.
3962 (child_open): Use target_kill rather than kill_inferior.
3963 (wait_for_inferior): Ditto.
3964 (insert_step_breakpoint, remote_step_breakpoint): Use
3965 new step_resume_break_shadow.
3967 * inftarg.c (child_wait): If all child processes die,

3976 * printcmd.c (print_command_1): Initialize "fmt" if no format
3977 is specified by the user.
3978 (print_frame_args): Only add to args_printed if we are
3979 actually fetching args from the stack (avoiding undefined
3981 (_initialize_printcmd): Remove bogus \{ from string.
3983 * remote-eb.c (eb_open): Avoid coredump on no argument.
3985 * remote-nindy.c: Bring out of Intel environment into new
3986 target environment. Remove all conditional compilation on
3987 I80960. Massive hacking throughout.
3988 (nindy_xfer_inferior_memory): New routine stolen from
3990 (nindy_create_inferior): New routine pieced together, probably
3991 not quite working yet.
3992 (nindy_ops): New target_ops struct for nindy.
3994 * remote-vx.c: Use write_memory rather than target_write_memory
3995 to get error checking.
3996 (vx_add_file_command, vx_open): Use symbol_file_add rather than
3998 (vx_create_inferior): Use target_terminal_ours...
4000 * signame.c (_initialize_signame): Always initialize, since
4001 we need the table for things other than psignal.
4003 * solib.c (solib_add): Use symbol_file_add, not add_file.
4004 (solib_address): Return boolean result rather than struct
4005 pointer which nobody else knows the type of.
4007 * sparc-tdep.c, valops.c: Use write_memory rather than
4008 target_write_memory, to get error checking.
4010 * stack.c (locals_info, catch_info, args_info,
4011 get_selected_block, frame_command, up_command): Use
4012 target_has_stack, rather than have_inferior_p or
4015 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4017 * symfile.h: New file, defining the interface between the
4018 generic and object-file-specific symbol reading code.
4020 * symtab.c: Move generic symbol-reading interface to symtab.c,
4021 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4022 table to map BFD targets to symbol-reading modules in GDB.
4023 Change index to strchr.
4024 (lookup_struct_elt_type): Use error() rather than hand-made
4025 simulations thereof.
4026 (lookup_partial_symbol): Speedup slightly when length == 0.
4027 (symbol_file_add): New function.
4028 (symbol_file_command): Call it.
4029 (symfile_open, symfile_init): New function.
4030 (add_file_target_command, add_file_addr_command): moved from

4035 * target.h (target_files_info): Don't declare, never called
4038 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4039 files to determine stack end address.
4041 * valarith.c (value_x_binop, value_x_unop): Change error message
4042 to be more useful. Pass proper argument to value_struct_elt.
4044 * valops.c (value_assign): FIXME comment that long long
4045 bitfields will break here.
4047 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4048 Update `make saber_gdb' to work better.
4050 * TODO: A woman's work is never done.
4052 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4053 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4054 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4055 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4056 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4057 valops.c, valprint.c, exec.c: Lint.
4060 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4062 Continuing Intel 960 port merge of GDB.
4064 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4065 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4066 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4067 Wack over "make depend" so it handles files in subdirectories
4068 vx-share, nindy-share, bfd, and in the current directory.
4070 * blockframe.c (get_prev_frame_info): Remove fatal error
4071 if stack not defined.
4073 * core.c (core_open, core_detach): New functions that handle
4074 the old "core-file" command as "target core" and "detach" instead.
4075 (core_file_command): Call them.
4076 (core_xfer_memory): Use common routine xfer_memory.
4078 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4079 dbxread now uses bfd for everything but symbol reading itself.
4080 BFD internals are used to drag out the relevant file offsets.
4081 (partial_symbol_file_open): Change args all around for BFD.
4083 * symtab.c: Rename "value" to "val" everywhere, so we can
4085 (symbol_file_command): New command, moved from dbxread.c
4086 and coffread.c. It uses BFD to read the file, then vectors
4087 based on its type, to dbx or coff symbol readers.
4088 * symtab.h: Extern a few vars for symbol_file_command.
4090 * target.h: Breakpoint takes a char * save area, not a char **.
4092 * valprint.c (val_print): When unpacking bitfields, offset
4093 the address in gdb of the value, if it is declared with a shorter
4094 type. Remove the last "runtime kludge test" of host byte order.
4096 * utils.c: Remove old my_bfd_read routine.
4098 * stack.c (frame_info): Use target_has_stack. Print program counter
4099 register's actual name rather than "pc", since it's called the
4100 "ip" (instruction pointer) on the i960 (sigh).
4102 * target.c (target_command): Add command for selecting a target
4103 type and calling its open routine. This is used for initiating
4104 communication with a particular target, in a generic way.
4106 * tm-i960.h: Update for modern gdb. Remove semicolons from
4107 various macros. Handle reading struct return convention, and
4108 error-out attempts to return structs with the "return" command.
4109 Be sure gdb doesn't think we know how to call functions in the
4112 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4113 to i960_xxx in lower case.
4114 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4115 not being defined yet.
4117 * remote.c (remote_open): Call start_remote to initialize
4118 wait_for_inferior during open.
4119 (remote_xfer_inferior_memory): Return length written rather
4122 * remote-vx.c (target_command -> vx_open): Use new generic
4124 * remote-eb.c, inftarg.c, exec.c: ditto.
4126 * infrun.c: Fix comments.
4127 (attach_program -> child_open): Use new generic target command.
4128 (wait_for_inferior): Clear saved register values before target_wait,
4129 so target_wait can set some of them if convenient.
4131 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4132 Return success indicator, not void.
4133 (child_xfer_memory): Avoid fetching initial word if we'll
4134 overwrite it anyway.
4136 * infcmd.c (attach_command): Use new generic target open routine.
4137 (_initialize_infcmd): Update doc on attach and detach commands.
4138 (do_registers_info): Merge in a byte-order problem as a FIXME
4141 * findvar.c (find_saved_register): Avoid problem in current frame.
4142 (read_relative_register): Ditto.
4143 (write_register): Convert byte order on the way out.
4145 * exec.c (file_command): Add.
4146 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4147 (xfer_memory): Common function between core_xfer_memory and
4149 (exec_xfer_memory): Use it.
4151 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4153 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4154 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4155 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4157 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4159 Merge Intel 960 port of gdb, continuing...
4161 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4162 symbol_file_command): Pass from_tty arg to hush 'em up.
4164 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4165 Add magic numbers for 960 COFF format.
4167 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4169 Merge Intel 960 port of gdb, from Intel "1.2" release.
4171 CHANGE_LOG entries from their port, which was based on

4175 Remove temp file if download is interrupted.
4177 Wed Aug 1 09:08:33 PDT 1990
4178 Now uses binary protocol to talk to NINDY.

4180 Times out after 5 seconds when trying to talk to NINDY.
4182 Tue May 29 12:54:49 PDT 1990
4183 Added variable baud rate (-b switch).
4184 Source code reorganization.
4186 Thu Apr 26 11:09:55 PDT 1990
4187 More cleanup of batch mode; specifically, execute "-s", "-e", and
4188 "-se" switches as soon as they are encountered on the invocation line.
4190 Fri Apr 20 13:47:15 PDT 1990
4193 Thu Apr 19 09:54:28 PDT 1990
4194 Add 'reset' command.
4196 Wed Apr 18 09:48:07 PDT 1990
4197 After opening remote tty, wait for 1 second to go by without input
4198 from it before trying to talk to NINDY (fixes problems with the
4199 Heurikon HK80/V960E).
4201 Mon Apr 4 16:33:05 PDT 1990
4202 Some output was not being suppressed in 'batch' mode.
4204 Thu Mar 22 15:31:11 PST 1990
4205 Ask user if old symbol table should be deleted when new file is
4208 Allow user to run a program downloaded before gdb960 was brought up.
4210 Correct "exec-file" help message for i80960 context.
4212 Correct bug in calculating user space address: could occasionally
4213 corrupt user program.
4215 Make sure to zero low-order bits in rip's because of bug in 960CA
4216 A-step part: could cause operation faults when "next"ing across
4219 Correct bug that made it impossible to get source line numbers for
4220 code loaded at addresses higher than 0x7fffffff.
4222 Wed Jan 10 12:43:22 PST 1990
4223 Open remote tty for exclusive use.
4225 Fri Jan 5 12:14:42 PST 1990
4226 Correct disassembly (CA manual was right after all):
4227 opcode for sysctl is 0x659
4229 Mon Oct 23 12:03:04 PDT 1989
4230 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4232 Mon Oct 16 14:15:09 PDT 1989
4233 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4235 Mon Oct 2 15:56:31 PDT 1989
4237 Added 960CA disassembly support.
4239 To simplify maintenance:
4240 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4242 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4243 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4244 - made disassembly interface identical to that in gdmp960.
4248 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4250 * target.h: Allow targets to stack. Add target_has_memory,
4251 _registers, etc. Restructure memory access and "info files"
4252 to walk the target stack.
4253 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4254 target.c: Change tables to match target.h.
4255 * inflow.c (child_mourn_inferior): pop child_ops.
4256 (generic_mourn_inferior): Use new has_stack flag.

4258 * inftarg.c (child_files_info): New "info files" regime.
4259 * remote-eb.c: New memory regime, new info files.
4260 * remote-vx.c: New memory regime, new info files. Now use
4261 separate targets for VxWorks attachment to machine, and
4262 actually running a process under VxWorks, since one has
4263 stack & execution & regs and the other doesn't.
4264 * remote.c: New memory regime, new info files.
4265 * sparc-xdep.c (fetch_core-registers): New memory regime.
4266 * target.c: New routines and support for stacked targets,
4267 new memory regime, new info files regime.
4270 Generalize section handling for an arbitrary number of sections,
4271 including use of the new BFD (binary file) library.
4272 * gdbcore.h: Add struct section_table.
4273 * exec.c (build_section_table): Iterate all sections and
4274 record what gdb needs to know about them.

4281 * dbxread.c: Quick changes to make it compile with new BFD.
4282 * utils.c (error): Avoid using bfd_error in generic routines.
4284 * core.c (core_fetch_registers): Get from the ".regs" section of
4286 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4288 * inferior.h (attach_flag): Export.
4289 * infcmd.c (run_command): use new target_create_inferior.
4290 * infrun.c (child_create_inferior): Don't return result.

4295 * breakpoint.c (bpstat_num): Handle breakpoints which have
4296 since been deleted, such as temporary breakpoints.
4297 infcmd.c (program_info): ditto.
4299 * core.c (core_file_command): Display the frame where the core
4304 * remote-vx.c (target_command): Merge in target command from
4305 targ-vx.c. A few other cleanups.
4307 * TODO, Projects: Lots more stuff to do...
4309 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4311 Massive changes to wall off the remote-debugging interface
4312 behind a function vector. The port to handle VxWorks targets
4313 is also part of this.
4315 All files: Replace references to renamed functions,
4316 remove references to remote_debugging, remove references to
4317 have_include_file, have_core_file in favor of target_has_stack,
4318 target_has_memory, etc.
4320 * Modularize the breakpoint interface.
4321 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4322 a breakpoint instruction.
4323 breakpoint.c: struct breakpoint's shadow_contents now sized as
4325 (insert_breakpoints): Vector to target to install breakpoints.
4326 (remove_breakpoints): Vector to target here too.
4327 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4328 sparc-tdep.c (single_step): Use new breakpoint interface for
4329 the single-step breakpoints.
4330 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4331 New file, contains routines to insert and remove breakpoints by
4332 reading out the old contents and later replacing them. This is
4333 how ptrace breakpoints work, and many remote systems as well.
4335 * tm-vxworks68.h: New config file, overrides a few things for
4336 Wind River's preferences.
4338 * target.h: New file, for transfer vector used to talk to the
4339 inferior (child, attached, core, exec, remote, etc). All accesses
4340 to the thing being debugged should come through these vectors.
4341 target.c: New file, routines to handle transfer vector.
4342 (various files): Add transfer vectors XXX_ops for the various
4343 targets and pseudo-targets (core files, etc) we support.
4345 * breakpoint.c (bpstat_stop_status): Further explorations of
4346 watchpoints and why things don't work all the time.
4347 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4349 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4350 the local gdbinit if it doesn't already have it.
4352 * core.c (core_ops): add and install.
4353 Allow core debugging without exec file.
4355 * dbxread.c (free_and_init_header_files): Merge two fns.
4356 (end_symtab): Free named symbol table when a new version comes in.
4357 (read_dbx_symtab): Relocate all kinds of symbols with base
4358 address. First step toward handling different text, data, bss
4360 (add_file_addr_command): Renamed add_file_command.
4361 (add_file_command): Vector to remote handler.
4362 Add "load" as an alias for "add-file" command.
4364 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4365 non-returning functions.
4367 * exec.c: Add exec_ops, and push it as a target when an exec
4370 * infcmd.c (run_command): Pass executable file name and arg list
4371 separately when starting an inferior. Permit "run" when no exec
4372 file is specified, for VxWorks.
4373 (detach_command): Move to child_detach in inftarg.c.
4375 * inftarg.c: New file. Unix-child-specific routines, and the
4376 child_ops structure.
4378 * inferior.h (registers): Export "registers" as the way for
4379 target dependent register handlers to find gdb's local copy of
4380 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4381 since it is now used by places that want wait_for_inferior to
4382 handle the grunge but want to see every trap from the inferior.
4384 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4385 Eliminate remote_debugging hooks in terminal handling.
4387 * infrun.c: Replace start_inferior with child_create_inferior.
4388 Move all the hair of Unix shells and ptrace idiosyncracies into
4389 child_create_inferior, so remote handlers don't have to deal.
4390 Remove running_in_shell. Rename stop_after_attach to
4391 stop_soon_quietly, and use it in a few other places where we want
4392 to just call wait_for_inferior and get control back on the first
4393 trap. trap_expected now never takes a value > 1.
4394 (init_wait_for_inferior): Initialize static vars when a new
4397 main.c (gdbinit): Add new hook for .gdbinit file name, let
4398 it be overridden by config files as GDBINIT_FILENAME.
4399 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4400 Both of these are used for VxWorks gdb.
4402 mcheck.c: rename include file "gmalloc.c" to avoid problems
4403 with system include file "malloc.c".
4405 param-no-tm.h: New include file, same as param.h but does not
4406 include the default "tm.h" file. This is used in files where
4407 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4409 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4411 remote-vx.c: New file, VxWorks remote debugging support. Uses
4412 RPC routines that are shared with the target system, in directory
4415 remote.c: Vectorize remote interface.
4417 source.c: Globalize source_path, and make an alias "l" for "list"
4418 since we now have the "load" command.
4420 sparc-xdep.c: Use new param-no-tm.h.
4422 symmisc.c (free_named_symtab): Add new function from Wind River.
4423 However, ifdef it out for now while we think about what it should
4426 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4428 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4429 non-Unix-children handle this with their own code in the target
4432 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4433 source and target lists. Add vx-share to default list of include
4434 directories. Add new files to src and target lists: mem-break,
4435 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4436 ${srcdir} versions of munch and createtags are used.
4438 * valops.c (find_function_addr): Split out of call_function.
4439 (call_function_by_hand): Rename call_function; this function
4440 calls functions in the target by laboriously patching the target
4441 word-by-word with the right stack, args, regs, etc.
4444 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
4446 Handle AMD 29000 a bit better.
4448 * remote-eb.c (readchar): Mask received char log to make it readable.
4449 (remote_start): Pass arguments down to executing program.
4450 Make startaddr unsigned.
4451 infrun.c (start_inferior): Accept args, pass them to
4453 infcmd.c (run_command): Pass args down to start_inferior.
4455 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
4456 the target object file format.
4457 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
4459 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
4460 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
4462 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
4464 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.

4472 * sparc-tdep.c (do_restore_insn): Simplify.
4473 (sparc_frame_find_saved_regs): Simplify and fix what we find.
4474 (sparc_push_dummy_frame): Simplify and fix what we push.
4475 (sparc_pop_frame): Slightly more hair here, deciding whether
4476 we are restoring a saved PC or returning to a return address in %i7.
4477 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
4479 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
4480 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
4481 * obstack.h (chunkfun): ditto.
4482 * defs.h (xmalloc, xrealloc): ditto
4484 * utils.c (quit): Grab the terminal from the child if necessary.
4486 * inflow.c (term_status_command): Rename to term_info, change
4489 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
4490 (is_delayed_branch): Speed up.
4491 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
4492 Still missing some float ops, and needs testing.
4494 * Support for input and output radixes other than base 10
4495 * defs.h (input_radix, output_radix): Declare.
4496 * expread.y (yyparse, parse_number): Handle changes of input
4497 radix, and ambiguous names-or-numbers in radixes >10.
4498 * printcmd.c (print_scalar_formatted): Print formatted hex
4499 numbers in varying column widths.
4500 * valprint.c (val_print): Use output_format to print scalar ints.
4501 (set_input_radix, set_output_radix, set_radix): Create.
4502 (set_output_radix): Set output_format from output_radix.
4503 (_initialize_valprint): add `set radix' but leave the others off.
4505 * main.c (execute_command): Let stupid questions be turned off.
4506 (_initialize_main): Handle "set stupidity", etc.
4508 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
4509 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
4511 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
4513 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
4514 bfd stuff is still screwed up, but with some manual work, it
4517 * breakpoint.c (bpstat_do_actions): Start over if a command
4518 proceeds the inferior, since the inferior will have stopped and
4519 will need to have its new stop-actions taken care of.
4521 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
4522 compiler fits, simplify it.
4524 * gdb.texinfo (directory command): Doc new dir command.
4525 source.c (directory_command): "dir" now puts things on the front
4526 of the path, moves dups up front, and handles multiple names
4527 on the command line, inserting each one in order. It also
4528 blows away cached line and full_filename info.
4530 * stack.c (backtrace_command): Skip "more stack frames follow"
4533 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
4534 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
4535 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
4536 The only odd one was Gould NP1, which had defined vprintf to
4539 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
4540 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
4541 variable, inspect_it.
4542 valprint.c (print_string, val_print): Use the global inspect_it
4543 to indicate whether to print in Epoch style or normal style.
4545 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
4547 * printcmd.c (call_command): add an alias for the "print" command
4548 which runs expressions and doesn't print the result if void.
4549 (print_command_1): implement it.
4551 * command.c: Remove #if 0'd code. Initialize all the fields
4552 in add_cmd (). Rename do_nothing_command to
4553 not_just_help_class_command, and make it externally visible.
4554 command.h: add user_commands to struct.
4555 * main.c (define_command): Don't overload c->function with a char
4556 string as well as a function pointer.
4558 * eval.c (evaluate_subexp): Reinstall tiemann changes to
4559 calling convention of value_struct_elt () that got dropped in
4562 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
4563 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
4565 * tm-sparc.h (POP_FRAME): replace some constants with defines.
4567 * sparc-xdep.c (store_inferior_registers): defer stores to regs
4568 until a good time (e.g. when we are about to run the child),
4569 saving ptrace calls.
4570 * infrun.c (proceed): handle DO_DEFERRED_STORES.
4571 * tm-sparc.h: define DO_DEFERRED_STORES.
4573 * sparc-xdep.c (store_inferior_registers): when storing float
4574 registers, don't store stack regs too. When storing the SP,
4575 however, DO store the stack regs too. This fixes a bug in which
4576 the dummy frame is not recognized when a call_function finishes,
4577 because its frame pointer (in the stack regs) was never
4579 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
4580 even though we don't know how to read them from an inferior.
4581 valops.c (call_function): Comment about storing SP.
4583 * infrun.c (save_inferior_status): Save away the original bpstat
4584 chain so it can be restored later. Install the copied version for
4585 use by whoever saved the status. It will be blow away by
4586 restore_inferior_status, and the original chain restored. This is
4587 important for people who have pointers into the original.
4589 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
4590 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
4591 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
4594 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
4596 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
4597 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
4598 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
4600 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
4602 * Merge Mike Tiemann's multiple inheritance changes from Sun.
4603 Store the baseclasses in a type struct starting from array element
4604 0 rather than from the unusual array element 1.
4606 dbxread.c: the above.
4607 (virtual_context): Add
4608 Read new debug information about which virtual function table
4609 a virtual function is from, and store it in fn_field.fcontext.
4611 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
4612 TYPE_FN_FIELD_STATIC_P.
4614 symtab.c: the above.
4615 valops.c: the above. Handle pointer casts of object *'s.
4616 (search_struct_method): Add.
4617 (value_struct_elt): First arg is now a pointer to a value, and is
4620 valprint.c: the above.
4621 values.c (value_virtual_fn_field): Add type arg. Handle
4622 offsetting to the proper object when calling virtual fns.
4624 (baseclass_addr): Add valuep arg.
4626 * README: Document the current state of BFD config (missing).
4627 * TODO, ChangeLog, Makefile.dist: Roll version.
4628 * WHATS.NEW: Add summary of changes since 3.5.
4630 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
4632 * dbxread.c (read_struct_type): Clear bit vectors whenever
4634 symtab.c (B_CLRALL): define.
4636 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
4637 using == rather than =. Huh... This fixes the dreaded problem
4638 wherein builtin_type_int becomes TYPE_CODE_FLT.
4640 * core.c (info_files): Show the inferior pid.
4642 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
4643 already knows how to look in the source directory.
4645 * Remove psymtab hair from many places. Remove duplicated code
4646 for searching symbol tables. Hide psymtabs from most places.
4647 Make it fast to get from a psymtab to its symtab.
4649 blockframe.c (blockvector_for_pc): Remove psymtab hair.
4650 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4651 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4652 dbxread.c: export psymtab_to_symtab, make it work if called N times.
4653 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
4654 new symtab completely. New psymtabs get symtab pointer
4655 initialized to zero. Remove MI warning printf.
4656 symtab.h: Comments. Add psymtab to symtab pointer.
4657 (PSYMTAB_TO_SYMTAB): New macro.
4658 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
4659 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
4661 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
4663 (print_frame_info): Avoid special-casing symbols that have not yet
4666 * source.c (open_source_file): Quick path if we have already
4667 located the source file by its full name.
4669 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
4670 find_pc_psymtab. When a name is found in the misc function
4671 vector, search the symbol table for its mangled name, not the
4672 name that the user typed.
4674 * bfd.h: Fix missing comment terminators, make #endifs match.
4676 * valarith.c (value_less): Handle unsigned int comparisons.
4677 Add FIXME about pointer compares, which assume host and target
4678 pointers are the same.
4680 * command.c (do_nothing_command): lint
4681 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
4682 fix comments on debug symbol format for visibility. Actually set
4683 visibility of symbols.
4684 main.c (echo_command): lint; use <readline/history.h>.
4685 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
4686 obstack.h (_obstack_blank): Rearrange pointer math to avoid
4687 pointing past end of allocated memory; saber complains.
4688 obstack.h: Declare the external functions that we use.
4689 valarith.h: use <string.h>
4690 solib.c (solib_add): lint.
4692 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
4694 * main.c (initialize_main): Default info_verbose to off, now that
4695 symbol reading is fast.
4696 (quit_command): Avoid clobbering exec_bfd while quitting.
4698 * Initial BFD (binary file diddling library) merger:
4699 coffread.c: Change AOUTHDR to struct exe_hdr.
4701 core.c: initialize initialized data at compile time.
4702 (core_file_command): Move from coredep.c, convert to bfd.
4703 (xfer_core_file): Convert to bfd.
4704 exec.c (exec_file_command): use bfd routines.
4706 mips-tdep.c: Remove exec_file_command and friends.
4709 * coredep.c: (fetch_core_registers) Convert core_file_command to
4710 fetch_core_registers.
4711 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
4713 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
4714 (my_bfd_read): More bogosity, which I don't think we call.
4715 (program_name): Remove this atrocity asap!
4717 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
4720 values.c: allocate_repeat_value was not clearing the
4721 optimized_out field.
4722 (value_static_field): minor stylistic fix (wrong macro was used).
4723 valops.c (value_struct_elt_for_address): didn't work for C++
4726 * signame.c (_initialize_signame): Initialize signal names once.
4728 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
4729 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
4730 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
4732 * remote-eb.c: Support user-settable baud rates on the serial port.
4734 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
4736 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
4738 * tconfig/sun3os4: Remove warning about native assembler,
4739 since it also occurs in the xconfig file.
4741 * findvar.c (registers): Allocate some slop after `registers'
4742 to prevent stray accesses from trashing the next variable.
4744 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
4745 on the sun-3, by changing the #ifdef from `sun3' (which is not
4746 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
4747 vars, which happened to follow `registers' in the executable.
4749 * readline/history.c (history_search): Heed gcc-2's advice
4750 and parenthesize && inside ||).
4752 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
4753 tm-29k.c: Insert FSF copyright headers.
4755 * remote-eb.c: Better comments.
4757 * Makefile.dist: Update to 3.91.6.
4758 * TODO: note PREPARE_TO_STORE problem.
4760 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
4762 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
4764 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
4766 * infrun.c (wait_for_inferior, at end): Don't set up
4767 prev_* if the inferior no longer exists.
4769 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
4770 CANNOT_EXECUTE_STACK.
4771 valops.c (call_function): Use it.
4773 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
4775 * inferior.h (PC_IN_CALL_DUMMY): New macro.
4776 infrun.c (wait_for_inferior, 2 places): Use it.
4778 * values.c (value_being_returned): Only use
4779 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
4781 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
4782 right thing for remote-eb.c.
4784 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
4785 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
4787 * blockframe.c: Put get_frame_saved_regs inside #if !defined
4788 (FRAME_FIND_SAVED_REGS).
4790 * findvar.c ({fetch,store}_registers): Check for
4791 REMOTE_{FETCH_STORE}_REGISTER macro.
4793 * findvar.c (get_saved_register): Add argument lval and
4794 change meaning of argument addr.
4795 findvar.c: Change calls to get_saved_register to reflect
4796 new calling convention.
4797 valops.c (value_assign): Use get_saved_register instead of
4798 find_saved_register.
4800 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4802 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
4803 an (uninitialized) pointer to one. Use "&" when passing it
4806 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4808 * coffread.c (getfilename): Use DGUX x_offset and x_name if
4811 * coffread.c (symbol_file_command): Put semicolon after
4813 Put safe_to_init_tdesc_context in #if defined (TDESC).
4814 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
4815 coffread.c: #include <sys/stat.h>.
4816 (read_coff_symtab): Typo: in_source_files -> in_source_file.
4817 Add missing ')' in check for "lc%" and friends. Remove
4819 Declare read_one_sym() at top of file.
4820 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
4821 MC68WRMAGIC can have the same value without causing a duplicate
4824 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
4826 * Allow a Makefile to be built without building the
4827 tm and xm file links that screw up builds in subdirectories.
4828 This is done with `config.gdb none', then you can do things
4829 like `make gdb.tar.Z'.
4830 * tconfig/none: Config file for no target system
4831 * xconfig/none: Config file for no host system
4832 * config.gdb: If no TM or XM files are called out by the
4833 host or target file, don't make links for them.
4835 * cplus-dem.c: Add documentation.
4837 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
4838 simple error, so the user's gdb doesn't crash due to some object
4839 file problem (e.g. somebody is rebuilding the file out from under
4842 * printcmd.c (print_address_symbolic): demangle the symbol.
4844 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
4845 Motorola copyrights in it. Make "make gdb.tar.Z" work.
4846 (alldeps.mak): sort and uniq all results from this; duplicates
4847 hose gdb.tar.Z link building. Remove RCS files from
4848 tconfig and xconfig. Add config files for sun386. Add
4849 a few odd files to OTHERS and HFILES.
4851 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
4853 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
4854 Roll version number to 3.91.5. Make lint work in bindir.
4856 * README: Document cross-debugging and new file structure.
4858 * blockframe.c: Lint. Include "value.h" to declare read_register.
4859 (find_pc_partial_function): remove duplicate line.
4861 * command.h: Lint. Declare error_no_arg and dont_repeat.
4863 * tm-news.h: Remove inadvertently duplicated stuff.
4865 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
4866 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
4868 * config.gdb: Allow `config.gdb host target' form. Clean
4869 up previous change that printed bogus messages when you just said
4872 * core.c: #include "command.h" for lint.
4875 * main.c: Remove some casts of enums. Lint.
4882 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
4884 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
4885 read it from memory. This will allow us to save ptrace calls
4886 eventually. Changed caller single_step too.
4888 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
4889 that we aren't going to use, saving many ptrace calls, especially
4890 when watchpointing or single stepping. Use some #define's for
4892 (store_inferior_registers): Ditto.
4893 (core_file_command): Use some #define's for constants.
4895 * tm-sparc.h: Add #define's for some register numbers, so we
4896 can eliminate the use of random constants in sparc-xdep.c.
4898 * stack.c (frame_command, print_frame_info, up_command,
4899 down_command) Remove frame_changed, since it
4900 causes a bug and doesn't seem to do anything useful. In some
4901 places it was used as a flag, in others as a stack level (?).
4903 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
4904 default is to use the portable (vprintf) version rather than the
4906 * xm-news.h (MISSING_VPRINTF): Add.
4908 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
4910 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
4912 * Remove stuff that forces -Bstatic linking of gdb, and warnings
4913 about linking debugged programs -Bstatic in the sun?os4 config
4914 files in tconfig and xconfig subdirectories.
4916 * main.c (main): Remove unreached exit(0) now that we exit
4919 * Create TODO file for online bug list. There are too many
4920 "little" bugs to keep track of on paper.
4922 * Change Projects file to refer to bug-gdb@cygnus.com
4923 rather than kingdon@ai.
4925 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
4927 * Makefile.dist (VERSION): 3.91.4 now.
4929 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
4930 (condense_misc_bunches): Add sanity check that misc_count is
4931 the same as the number of symbols in the bunch.
4933 * coffread.c: rename init_misc_bunches. Pass an argument
4934 to condense_misc_bunches (a zero).
4936 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
4937 every time we are called; don't rely on our caller to do it.
4938 (add_file): Remove call to init_misc_bunches.
4940 * mipsread.c: Only warn, don't error, if unknown symbol types.
4941 This keeps an old gdb from falling on its face if it sees newly
4942 extended symbol info. Rename init_misc_bunches.
4944 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
4946 * Merge in changes from Per Bothner for DECstations and other
4947 MIPS stuff. The rest is Bothner speaking:
4949 The next message is a merger of Alessando Forin's mips port with
4950 mine. I've tried to use my good if biased judgment to get
4951 the best of both. It *does* need testing.
4953 Some of the changes are general, *not* mips-specific.
4956 Didn't believe in little-endian bit order.
4957 There are still inconsistencies about whether flags
4958 like BITS_BIG_ENDIAN are integer (#if ...) or
4959 boolean (#ifdef ...). I tried to paper over them.
4961 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
4962 Moved some misc_function code that was common to
4963 {dbx,coff,mips}read.c to symtab.c.
4964 In the process, I think I cleaned things up a bit.
4965 At the same time, moved obsavestring and obconcat to symtab.c.
4968 Removed obsolete condense_addl_misc_bunches (use
4969 condense_misc_bunches(1) instead).
4972 Needed to include <sys/dir>, at least on DECstations.
4974 valops.c, mips-tdep.c, tm-mips.h:
4975 Added PUSH_ARGUMENTS macro to support funny argument-pushing
4976 conventions (when STACK_ALIGN is insufficient).
4977 Needed on mips, where doubles need 8-byte alignment,
4978 but ints only need 4.
4981 Removed cruft that was not being used.
4982 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
4985 Print $ before register-names (I think that makes things a little
4987 Never print two instructions, even if one delays.
4988 Removed hex-disassemble set_cmd. (This is not mips-specific,
4989 so I think the argument is whether it is generally worthwhile or not.
4990 I'm inclined to think not, given how easy it is to
4991 convert between radixes in gdb.)
4994 This is basically Alessando's code.
4995 It doesn't use obstacks; I changed it to use obstacks
4996 in a few minor places where using malloc causes a
4997 memory leak. (Probably, more places could/should be changed.)
4998 I added record_misc_function where it was missing.
4999 In symbol_file_command and add_file_command, I tried
5000 to make the code consistent with more recent versions.
5001 Minor sylistic changes in parse_procedure.
5002 Make a .gdbinfo. psuedo-symbol point back to the real
5003 procedure symbol (using the isym field).
5006 This is basically from my port, but with a lot of details
5007 and a number of routines merged in from Alessando's version.
5008 I basically used my code "raw" backtrace (use heuristics
5009 from the actual code, rather than symbol table info) - though
5010 the idea is Alessandro's. I feel my code is a little cleaner
5011 here, particularly in being a little more flexible, such as being
5012 able to handle gcc-produced code (which it now can).
5013 It also doesn't do frame caching (which is not useful
5014 more recent gdb versions).
5015 I also used my code for push_/pop_dummy, more or less.
5016 I tried to incorporate AF's code for testing sigtramp
5017 while backtracing; I probably got it wrong.
5018 Added mips_print_register, which tries to scrunch as much
5019 information as possible on a screen...
5020 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5021 under mips-pinsn.c), I don't see anything mips-specific here,
5022 and I don't see it being all that useful anyway.
5025 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5026 Use more register names (rather than hard-cases numbers).
5028 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5030 * Hack up 3.90.11 changes:
5032 * Makefile.dist (depend): parameterize $(GCC).
5033 Add solib.c and solib.o.
5034 (readline): Fix vpath for both absolute or relative SRCDIR.
5036 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5037 Also, let the part I didn't understand at least compile so
5038 I can test the rest. FIXME.
5040 * dbxread.c: Fix thinko using strcmp.
5041 (init_psymbol_list): declare static.
5042 (partial_symbol_file_open): Comment cleanups better, avoid
5043 cleaning up the string table since the caller will do that.
5044 Move the stat for mod time into symbol_file_command, temporarily.
5045 (There should be a mod time for each symbol file, eventually,
5046 to control its rereading. FIXME.)
5048 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5049 SunOS, which gives error for shared libs otherwise. (From
5050 Schaefer, probably FIXME needs work for portability.)
5052 * solib.c: Move #include "param.h" to work.
5053 Lowercase all the Uppercase Letters In the Messages.
5054 (find_solib): Clean up inferior_so_name for debug printouts.
5055 Allow no argument, to mean all shared libraries.
5057 * symmisc.c: include param.h to get CLEAR_SOLIB.
5059 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5061 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5062 to 3.90.11. ChangeLog entries below are from this.
5064 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5068 * Makefile.dist (HFILES): Add tm-sunos.h.
5070 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5074 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5076 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5078 * sparc-opcode.h Added single-operand version of rett.
5080 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5082 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5083 Put parens around gcc_p in expansion.
5085 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5087 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5089 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5091 * Changes for Sun shared libraries:
5092 blockframe.c (find_pc_partial_function): If a non-text symbol
5093 is found, set *address = pc - FUNCTION_START_OFFSET.
5094 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5095 Disable breakpoints instead of giving an error.
5096 source.c (select_source_symtab): Initialize cs_pst.
5097 symmisc.c: Call CLEAR_SOLIB if defined.
5098 symtab.h: Make text{low,high} CORE_ADDR not int.
5099 (psymtab): New field addr.
5101 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5102 (record_misc_function): Give correct type for N_DATA symbols.
5103 (condense_misc_bunches): do "misc_function_count = j" regardless
5105 Take code which is shared between symbol_file_command and
5106 add_file_command and put it into partial_symbol_file_{open,read}.
5107 Split add_file_command into add_file_command and add_file.
5108 Make psymtab_to_symtab read in the string table if the file
5110 Two new parameters to read_dbx_symtab and start_psymtab.
5111 tm-sunos.h: New file.
5113 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5115 * infcmd.c: Change cont_command to continue_command and "cont"
5118 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5120 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5122 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5124 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5125 size 1,2,4,8 rather than size < 8.
5127 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5128 as necessary, not just once.
5130 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5132 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5134 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5136 * tm-news.h: Add CALL_DUMMY_*.
5138 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5140 * config.gdb: In list_host, list_target, use ${i}, not $i.
5142 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5144 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5146 * sparc-opcode.h: Change all store floating-point state register
5147 instructions to have the right match & lose fields.
5149 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5151 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5153 config.gdb: If srcdir != ., create readline directory and
5154 copy a makefile into it.
5156 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5157 consistency with POSIX.
5159 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5160 when we exit its exp_valid_block.
5162 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5164 * Makefile.dist: Bump version to 3.91.3.
5166 * Clean up handling of breakpoint commands (somewhat).
5167 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5169 inferior.h: Add breakpoint_proceeded to inferior status struct
5170 and globals; save it and restore it.
5171 (clear_breakpoint_commands): Cleanup, remove old #define.
5173 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5174 (save_inferior_status, restore_inferior_status): handle it also.
5175 (proceed): Remove earlier code that set breakpoint_proceeded.
5176 It is now set only in clear_proceed_status.
5177 (clear_proceed_status): Cleanup, use bpstat_clear rather
5178 than clear_breakpoint_commands. No callers need the stop_bpstat
5179 between clear_proceed_status and proceed.
5181 infcmd.c: Add breakpoint_proceeded definition and comment.
5182 (cont_command, jump_command, signal_command): Move call to
5183 clear_proceed_status right next to call to proceed.
5185 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5186 caller's argument while running down the chain of breakpoints.
5187 Use new variable "breakpoint_proceeded" to determine when
5188 a command that it executes moves the inferior past the
5190 (bpstat_clear): Handle NULL argument.
5191 (bpstat_clear_actions): Avoid useless call to
5192 breakpoint_auto_delete.
5193 (delete_breakpoint): Clean up bpstat's that are pointing to
5194 the deleted breakpoint from the stop_bpstat chain.
5195 (breakpoint_auto_delete): Simplify.
5197 * Clean up handling of EOF, error on stdin, etc. This was
5198 prompted by a network problem that caused gdb to go into an
5199 infinite loop filling up its malloc'd memory.
5201 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5202 not clear_breakpoints_commands, which is now gone.
5203 (main): If command_loop returns (e.g. from EOF on stdin), do
5204 a quit_command (looping back to command_loop if quit_command
5205 doesn't really quit).
5206 (command_loop): check result from command_line_input and
5207 exit if it returns NULL, rather than passing the NULL to
5209 (gdb_readline): Free malloc'd result space before returning
5212 * utils.c (query): Handle C-d to mean "yes", just as if the
5213 input was not a terminal. Also avoid infinite loop if EOF
5214 occurs in mid-input-line before newline. This allows
5215 query to be used at EOF on stdin with reasonable results.
5217 * infrun.c (proceed): Set breakpoint_proceeded.
5219 * values.c (value_as_long): Avoid infinite recursion for enums.
5220 (_initialize_values): Fix typo in help msg (kingdon).
5222 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5223 RL_LIB for linking. This allows -lreadline for linking
5224 and nothing for dependencies, once readline is a real library.
5226 * config.gdb: Jim Kingdon: give useful error message if the
5227 host or target type is not recognized.
5229 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5230 it just defines it. Dumb, but deal with it.
5232 * Jim Kingdon suggests:
5233 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5235 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5237 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5239 * Clean up Bothner's changes.
5241 * blockframe.c (clear_pc_function_cache): New function.
5242 * blockframe.c: remake cache_pc_function_* static.
5243 * dbxread.c (symbol_file_command): remove references to
5244 cache_pc_function_* variables.
5245 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5246 * printcmd.c: Avoid kludging a global variable (addressprint)
5247 to avoid printing the address of a string twice. Instead,
5248 pass the format letter 's' down low enough that it can be seen
5249 to avoid this problem.
5250 (print_formatted): Pass format arg to value_print.
5251 (restore_addressprint): Remove function.
5252 (do_examine): Avoid hacking addressprint, cleanups and such.
5253 (print_frame_args): Add a comment to a Bothner change.
5254 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5255 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5256 to wipe out the values cached in blockframe.c.
5257 * symtab.c (find_method): Add comment saying how big you must
5258 allocate to be "big enough". Per being terse again.
5259 * valprint.c (val_print): Handle format letter "s" to print
5260 strings without addresses. Add comment to vtbl printing code
5261 which casts with wild abandon. Rearrange reference-printing
5263 @0xaddr: value (print w/addressprint)
5264 value (print w/~addressprint)
5265 @0xaddr (parameter lists w/addressprint)
5266 or nothing (parameter lists w/o addressprint)
5268 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5270 * Merge more changes from Per Bothner:
5272 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5273 annoying) that I tried to improve it. Here are my suggestions.
5275 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5278 Do automatic de-reference when taking the address of a reference.
5280 Don't deref_ref when printing parameter lists.
5282 More attempts at treating refernences properly.
5284 In val_print, if deref_ref==0, don't print dangling " = ".
5286 Add COERCE_REF macro, which de-references an REF.
5288 * Merge changes from Per Bothner:
5290 * Fixed (Sony news)-specific configuration problems.
5291 * Fixed other problems with using vanilla pcc and libc (enum problems;
5292 assumption that vsprintf exists).
5293 * Some major speed-ups (finc_pc_partial_function now caches a match;
5294 parsing avoids duplicate symbol_lookup calls).
5295 * Changed handling of baseclasses (no longer use baseclasses field
5296 of struct type, use the first n_baseclasses fields instead).
5297 * Various minor changes/fixes, most C++-related.
5300 Cache the most previous match from find_pc_partial_function.
5301 (Save both low and high ends of matching function's pc range.)
5302 This speeds up the loop of infrun.c:wait_for_inferior quite
5303 a bit, and makes step/next commands much zippier.
5305 Added an enum->int cast (otherwise, some compilers barf).
5307 No longer set baseclass offset to 0, since multiple
5308 inheritance now mostly works.
5309 Added a number of casts, to shut up compiler warnings
5310 (after stabs where made enums, not ints).
5311 When discarding a symbol table (in symbol_file_command),
5312 must clear the cache introduced in blockframe.c.
5313 Don't convert $vtbl_ptr_type to vtbl any more.
5314 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5315 Mask off sign bit emitted by g++ for virtual table offset.
5316 Set voffset to -1 (not 1) for static member functions.
5318 Changed parsing/lexing of names to avoid doing symbol lookup twice
5319 (once when lexing to determine symbol class, once for real).
5320 Now only call symbol_lookup once. Fields of 'this' win especially big.
5322 Subpress printing addr twice in the case of 'x/s addr'.
5324 lookup_basetype_type is no longer used.
5325 Add find_methods as recursive helper function to decode_line_1.
5326 This allows multiple inheritance to work.
5327 Also, once one or more matches has been found, do not look in
5328 base-classes. (Baseclass methods would be overridden, anyway.)
5330 Removed baseclasses array in struct type.
5331 Instead of using baseclasses[i], use fields[i-1].
5332 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5333 Changed sign convention of voffset (previous was inconsistent).
5335 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5337 Used to assume existence of vsprintf. Re-written to not need it
5338 if HAVE_VPRINTF is undefined.
5340 typecmp was too pessimistic. Made it less so.
5342 Don't print space after address.
5343 If vtable points to a misc symbol (with 0 offset), print it,
5344 since that indicates the actual class of the object.
5345 Changed ype_print_derivation_info to use new inheritance
5346 scheme (without baseclasses vector).
5348 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5349 Also, changes needed because TYPE_BASECLASSES were removed.
5351 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5353 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5356 If there is no path set, and the symbols don't indicate what directory
5357 a file was compiled in, look in the current directory. But either
5358 a path or a known compilation directory will prevent this.
5361 Three independent bug fixes:
5362 * Remove the #if 0 block that breaks some stuff.
5363 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5364 adapt gdb to either SunOS 4.0.* or 4.1.
5365 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5368 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5371 (type_print) Demangle the name being printed.
5372 (type_print_base) Handle botched demangling without coredump (tiemann).
5375 (check_stub_method): Document routine.
5376 (tiemann) fix bug for no-arg functions
5377 Avoid clobbering beyond end of malloc'd storage.
5378 Terminate the argument list properly.
5380 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5382 * Changes merged by John Gilmore:
5385 In breakpoint_1, use new print_address_symbolic instead
5386 of find_pc_partial_function. (This forces use of assembler-level
5387 addresses, and avoids misleading non-mangled source-level names.)
5389 Generalize ansi argument such that -1 means skip arglist totally.
5390 Removed global variable print_ansi_qualifiers (which made
5391 code non-reentrant), in favor of extra explicit arguments
5392 to internal routines.
5394 Add new helper function print_address_symbolic.
5395 Use find_pc_misc_function instead of find_pc_partial_function
5396 (since we want assembler-level symbols here).
5398 Print unknown function as just "f (...)", not "f (...) (...)".
5399 Use new fputs_demangled explicitly.
5401 Fixed a typing violation (problem: value.h cannot be imported
5402 without renaming many variable in this file).
5403 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5404 decode_line_1: Moved forward some never-reached code.
5405 Made decode_line_2 skip function prologues correctly.
5407 fputs_filtered should not demangle by default.
5408 Add new fputs_demangled to demangle on demand..
5410 Change value_struct_elt to use value_primitive_field (using recursive
5411 utility function search_struct_field). This allows foo.bar to work
5412 for multiple inheritance (so far only for data fields).
5413 Change check_field in the same way (recursive helper function
5414 to support multiple inheritance).
5415 (Note: there are more of these problems that I haven't fixed.
5416 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5417 value_of_this: 'this' symbol name is now just "this", note "$this".
5419 Don't print static members.
5420 Avoid printing "members of <type>" if there are none.
5421 Simplified type_print_derivation_info by merging duplicate code.
5422 Remove useless blank lines in type_print_base (ptype command).
5424 Added declaration of new routine value_primitive_field.
5426 Added value_primitive_field which is generalized version of
5427 value_field that can handle multiple inheritance (non-zero offsets etc).
5428 Re-implemented value_field to call value_primitive_field.
5430 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
5432 * infcmd.c -- insert else to avoid 'delete env' coredump when you
5433 delete the whole environment. Karl Berry reported the bug.
5434 * source.c - fix openp to avoid //'s in filenames, which
5435 trigger an Emacs bug causing it to not be able to find files
5436 when running gdb in a window.
5437 * dbxread.c - zap the #if 0 that botches the add-file code.
5438 It seems to work a lot better without all the code commented out.
5440 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
5442 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
5445 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
5447 * Makefile - added a ${CFLAGS} to a couple of entries,
5448 added remote-sa.sparc.c
5449 * added remote.sa-sparc.c, a modification of remote.c
5450 which conducts a dialog directly with the SparcStation prom.
5451 * breakpoint.c, infrun.c, sparcdep.c added
5452 remote_insert_breakpoint(), and remote_remove_breakpoint()
5453 to breakpoint.c instead of directly writing breakpoint instructions.
5454 * sparcdep.c on remote_debugging,there is no need
5455 to remove signle step breakpoint instructions.
5456 * main.c added "-epoch" flag and "int epoch_interface" to main.c
5458 * printcmd.c - epoch interface sends lisp expressions to open up
5459 epoch windows on inspection.
5460 * valprint.c - added arrayprint, and addressprint and made adding
5461 format controls easier
5462 * wait.h added a couple of undef's because we were getting
5463 complaints about WSTOPSIG and WTERMSIG begin redefined.
5466 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
5468 * symtab.c (decode_line_1): Add support for handling method stubs
5469 in the type information.
