1 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
3 * infrun.c (wait_for_inferior): Fix step/next so that you only
4 stop at the beginning of a new line. This fixes various problems
5 with for loops, nested if-else's and switch statements.
7 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
9 * dbxread.c: Enable, but soften, const_vol_complaint.
10 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
11 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
12 should be file-scope, not global.
13 (read_struct_type): Remove ancient multiple-inheritance warning.
14 (read_range_type): Check base type, complain & patch if undefined.
15 * stack.c (frame_info): Demangle the function name in `info stack'.
18 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
20 * eval.c (evaluate_subexp_for_address): Don't use
21 TYPE_POINTER_TYPE directly (it might be zero if this type has
22 never had a pointer created before); use lookup_pointer_type.
23 * symtab.c (lookup_method_type): Arguments were swapped in all
24 callers, so fix it here. I'm amazed this worked at all!
26 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
28 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
29 "bss" rather than "data" symbols, but which still conflict.
32 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
33 * core.c (core_files_info): Shorten output.
34 * exec.c (exec_files_info): Ditto.
35 (build_section_table): Ignore zero-length sections.
36 * language.c, printcmd.c: Lint.
37 * language.h (get_frame_language): Declare.
38 * saber.suppress: update.
39 * stack.c (find_relative_frame): Remove complex code that was
40 #if 0'd, stick with simple code. Lint.
41 * saber.suppress: Update a bit.
42 * symfile.c (add_symbol_file_command): Add "?" to question.
43 * utils.c (parse_escape): Avoid \a due to bdead compilers.
44 * value.h: Declare typedef_print.
46 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
49 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
50 (Reported by Mark Peek <mark@imagen.com>.)
52 * solib.c (solib_map_sections): Relocate all sections, even
53 though only the text section's size is tracked. Mark ld_text
54 for eventual elimination as we generalize to N sections.
56 * infrun.c (wait_for_inferior): Don't check if the PC is in a
57 call_dummy if we were stopped by a random signal that is being
58 passed to the program. This produced wierd results when calling
59 functions in the inferior and signals (e.g. SIGALRM) were in use.
61 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
63 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
64 Bugfix from Paul Eggert <eggert@twinsun.com>.
65 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
66 * valprint.c (print_floating): Print 9 digits for IEEE floats.

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

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

282 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
284 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
285 entries are enclosed herein. Not all of these changes
286 have been merged into the master GDB sources -- check the
287 ChangeLog above here for the merge log.
289 Mon Jun 3 17:05:45 EDT 1991
291 m2-exp.y Created. Tested outside of GDB for a few days. Proper
292 operators were added, C specific operators and tokens
293 removed. yylex() revamped to some extent. Still things
294 missing from the grammar, such as sets.
295 Tested for two weeks in GDB v3.5.
297 Tue Jun 11 17:23:48 EDT 1991
299 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
300 so they are built-in. Sort of a hack.
302 Fri Jun 14 12:53:51 EDT 1991
304 m2-exp.y Added range checking for numeric constants. Any numeric
305 constant is assumed to be of builtin type INTEGER unless:
306 (1) it is octal or hexadecimal, in which case it is a
307 CARDINAL; (2) it is too big to fit into an INTEGER, in
308 which case it is a CARDINAL.
309 eval.c Added simple range checking for +, -, and * on integers.
310 Doesn't work very well for *, since 6 * 1,000,000,000 =
311 1,705,032,704, which fails the simple test of result >=
312 first_operand, no matter in what order the operands are.
314 Tue Jun 18 14:11:30 EDT 1991
316 Broke the parser into parts, one containing the C grammar and the other
317 containing code to be shared by all of the grammars.
319 The following files no longer exist:
324 The following files were added:
326 c-exp.y (The C grammar)
327 m2-exp.y (The Modula-2 grammar)
328 parser-code.c (Code that is shared by the above grammar)
332 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
333 now necessary to use the Bison compiler compiler, since it
334 will generate function/variable prefixes other than yy.
336 Tue Jun 18 16:47:49 EDT 1991
338 symtab.[ch] Added the external variable working_lang, than holds the
339 value of the current working language.
340 Added the ennumerated type language_mode, with the values
341 language_auto and language_manual, the former meaning that
342 GDB sets working_lang as needed, and the latter meaning
343 that the value of working_lang is totally under user
345 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
346 REAL, BOOLEAN and CHAR. Also added the type codes
347 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
348 utils.c Added set_language_command and show_language_command to
349 implement the GDB support commands "set language" and
351 expression.h A number of identifiers were added to the type exp_opcode
352 to facilitate Modula-2 builtin functions, integer
353 division, and array indexing.
355 Wed Jun 19 13:25:58 EDT 1991
357 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
358 if the language specified by working_lang requires the use
359 of strict typing of expressions. Eventually, even this
360 will be able to be changed by the user.
361 Added the macro RANGE_CHECK, which evaluates to non-zero
362 if the language specified by working_lang requires the
363 checking of a value against the domain of its type.
364 Eventually, even this will be able to be changed by the
366 language.[ch] Predicates involving types (simple_type, ordered_type,
367 same_type, integral_type, numeric_type, character_type,
368 boolean_type, float_type) are added. These predicates are
369 based on the current value of working_lang, and are handy
372 Wed Jun 19 15:39:34 EDT 1991
374 eval.c Added the function type_array_rank which computes the rank
376 valarith.c Added the funtion value_bool, which when given a integer
377 value.h value (ie. struct value *) as an argument, it returns a
378 boolean value (ie. struct value *) true if that integer
379 is non-zero, and a boolean value false otherwise.
380 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
381 will print out properly.
383 Wed Jun 19 16:36:34 EDT 1991
385 valops.c Added the function value_capitalize, which returns it
386 value.h argument capitalized if its argument is a lowercase
387 letter, or the argument unchanged if its argument is not a
389 valarith.c Added the function range_check_p, which returns non-zero
390 value.h if its value argument is between the integral bounds upper
392 Added the function range_check_enum_p, which makes sure
393 that its value argument is a valid member of the domain of
395 Added the function range_check_range_p, which makes sure
396 its value argument lies between the upper and lower bounds
397 of its type argument, which must be a ranged type.
398 Added the function check_array_index, which range and type
399 checks an index of an array.
400 Added the function value_multi_subscript, which computes
401 array[idx1,idx2...idxN], given a value array and an array
402 of values representing indicies.
403 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
404 unpack_long to work with TYPE_CODE_BOOL and
407 Wed Jun 19 18:04:08 EDT 1991
409 symtab.c Stored pervasive types in a structure and make
410 lookup_pervasive_type() a lookup function that was based
411 on working_lang. If lookup_pervasive_type() returned
412 non-zero, then that value was returned (a fix, since
413 before it simply wouldn't return the pervasive type.)
414 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
415 non-zero if the language specified by working_lang means
416 "conversion" when it says "cast".
417 valops.c Added the function value_real_cast(), which performs a
418 value.h *cast*, not a *conversion*, which is what value_cast()
419 does when it can. In particular,
420 value_cast(<float_type>,4) = 4.0, while
421 value_real_cast(<float_type>,4) = some mess.
422 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
423 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
424 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
425 and MIN on integral types. *NOTE*: These are currently
426 hardcoded to work only if there are 8 bits per storage
428 eval.c Made logical functions call value_bool to return a
429 properly typed boolean value, based on working_lang.
431 Thu Jun 20 11:55:27 EDT 1991
433 valprint.c Types now print out in a Modula-2 fashion. This works for
434 the cases when the type is printed out step-by-step, that
435 is, it doesn't work when the name of a structured type
436 (which includes the keyword "struct", etc.) is simply
438 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
439 since type specifications in C and Modula-2 are very
440 different. The C printing of a type is very recursive,
441 whereas in Modula-2 it is generally very simple. C has
442 type prefixes and suffixes, which have no real analogue in
443 Modula-2. Maybe type_print() should call a language
444 specific type printer. This is also advantageous if we
445 compile GDB to exclude some of the languages. We'll just
446 leave those functions out.
448 Thu Jun 20 16:57:10 EDT 1991
450 dbxread.c When reading the complete symbol table in (via
451 psymtab_to_symtab()), the number and types of function
452 arguments are added to a function type. define_symbol()
453 calls add_param_to_type() to accomplish this.
454 Assumption: when we come across a function definition
455 (N_FUN symbol with an 'f' or 'F' in the name), its
456 arguments will appear before another function definition.
457 When a function is found, a pointer to its type is placed
458 in the global in_function_type. Changes that
459 add_param_to_type() makes are to this global.
460 valprint.c The type of a function now includes (for Modula-2) the
461 types of its parameters.
462 eval.c Type checking and a check for the proper number of
463 arguments is now done for function calls. Not sure of the
464 impact this has on C++ member function yet.
466 Thu Jun 20 19:58:48 EDT 1991
468 valprint.c Rewrote the type printer. Broke it into two language
469 specific parts, adding the functions type_print_m2() and
471 An unfortunate consequence is this: if you debugging a C
472 program in Modula-2 mode (why?), info types does not work
473 well with regular expressions, since the types are printed
474 out in Modula-2 terminology, but stored in C terminology.
475 language.[ch] Added the functions new_type_last(), type_keyword(), and
476 type_sep() to aid in the printing of typedefs.
477 symtab.c Made the printing of typedefs as language independent as
478 possible through calls to new_type_last(), type_keyword(),
481 Fri Jun 21 11:50:26 EDT 1991
483 dbxread.c Check all incoming ennumerated types. If it looks like
484 Modula-2's BOOLEAN type, then change the type_code of the
485 type to TYPE_CODE_BOOL so we can process it as a boolean
487 valprint.c Replaced some of the 0x%x with calls to sprintf and
488 hexformat() in val_print().
489 language.[ch] Added the function hex_to_string(), which converts its
490 integral argument to a hexadecimal number (format is
491 language based) and returns the result as a string.
493 Mon Jun 24 12:25:07 EDT 1991
495 valprint.c Some functions call type_print_1() directly, instead of
496 value.h using type_print(), so they can specify where (column) to
497 print things. Since type_print() takes care of language
498 dependence, that needs to be called first. Added a
499 parameter depth to type_print() (so it is now like
500 type_print_1). Changed type_print to type_print_at, and
501 made type_print a macro that passes a depth argument of
503 symmisc.c Changed all calls to type_print_1 to calls to
505 Makefile.dist Made it possible to build GDB for a specific set of
506 depend languages. Do this by passing a definition for the macro
507 LANGS to make. LANGS should be a string containing a
508 space-separated list of language names (ie. LANGS="c m2").
509 The default is to build all languages. Note that grammar
510 files must follow the naming convention of <lang>-exp.y.
511 gdb.lang This holds the current value of the LANGS macro. It is
512 examined every time make is called, and is updated if
514 eval.c Added #ifdef _LANG_<lang> to these files.
515 expread.c Still need to add them to dbxread.c and coffread.c.
523 Mon Jun 24 16:33:11 EDT 1991
525 language.[ch] Added the functions hexformat_pre() and
526 hex_to_string_pre(), which take a prefix argument to
527 include in the format string. Thus, hexformat_pre("08") will
528 return "0x08x" (if the working language is language_c).
529 Made hexformat() and hex_to_string() calls to the above
530 with "" as the prefix argument.
532 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
533 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
534 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
535 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
536 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
537 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
538 valprint.c, vax-pinsn.c
540 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
541 calls to hexformat() and hex_to_string(). Format strings without
542 the leading "0x" were ignored.
544 depend Updated to take the above into account.
547 Tue Jun 25 15:27:18 EDT 1991
549 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
550 and type_check_t to keep track of the current state of
551 range and type checking.
552 main.c Added the variables range_mode, range_check, type_mode,
553 and type_check to record the current state of range and
554 type checking. Added initialization code to main().
555 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
559 Tue Jun 25 17:57:08 EDT 1991
561 dbxread.c process_one_symbol() updates the variable (enum language)
562 source_lang based on the extension of the filename
563 contained in the N_SO sybmol that started this symtab.
564 When end_symtab() is called, the value of source_lang is
565 put into the language field.
566 stack.c select_frame() sets working_lang (and possibly type_check
567 and range_check) to the language field of the symtab
568 associated with the frame that is selected if working_mode
569 is language_auto. If working_mode is language_manual, a
570 warning is printed and working_lang is not set.
571 language.c Added the function set_type_range(), which sets the value of
572 type_check and range_check (if their modes call for
573 automatic setting) based on the current value of
574 working_lang. A non-zero argument will cause the current
575 settings to be output.
578 Wed Jun 26 14:51:40 EDT 1991
580 eval.c Added range checks on assignment.
581 m2-exp.y Added the grammar for sets to the language. Currently,
582 these do not do anything except print an error message.
584 Wed Jun 26 17:01:04 EDT 1991
586 m2-exp.y Added the ability for parse_number() to parse negative
587 numbers. A global flag is set upon encountering a unary
588 minus. This was done to make, for example, 1 parse as a
589 CARDINAL, and not as an integer, per Wirth's examples in
590 Programming in Modula-2 ed.4.
591 valprint.c Added support for "set radix 2" by then setting
592 output_format to 't'.
593 eval.c Implemented range checking on subrange types. Added calls
594 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
595 Implemented MIN and MAX for ennumerated types. The
596 minimum value of an ennumerated type is defined by Wirth
597 as the first identifier, and the maximum as the last.
598 m2-exp.y Made octal numbers ending with "B" be characters and those
599 ending with "C" be numbers, per Wirth's book. (p. 34)
601 Thu Jun 27 14:11:52 EDT 1991
603 stack.c select_frame() now only sets working_lang, it does not
604 notify the user. If working_mode is language_manual, then
605 a warning is issued once.
606 main.c At the end of each call to execute_command(), working_lang
607 is checked against the local static (enum language)
608 current. If they differ and working_mode is
609 language_auto, the new settings of language, type and
610 range checking are printed out.
611 stack.c Modified frame_info() to include the language of the
612 current frame in the output of "info frame".
613 language.[ch] Added the function language_str() which returns the name
614 of the current language.
616 Fri Jun 28 15:33:14 EDT 1991
618 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
619 the language. INCL and DECL currently cause an error,
620 since sets are not implemented yet. INC and DEC are
621 implemented as PREINCREMENT/PREDECREMENT with one
622 argument, and as ASSIGN_MODIFY with two arguments.
623 eval.c Added type checking to the above cases.
624 value.h Added not_lval_constant to the lval_type ennumerated type.
625 not_lval_constant means that the value is a constant
626 value; that is 3 or 'a' or TRUE, not as in a constant
627 identifier. This is used to help coerce numbers such as 3
628 to either signed or unsigned numbers.
629 valops.c Added the function value_coerce_constants() which coerces
630 constant integers as following: if one is a constant and
631 the other is not, the constant's type is set to the type
632 of the other argument. If both are constants and one is
633 signed, the other is converted to a signed constant.
635 Sat Jun 29 17:26:29 EDT 1991
637 valarith.c Added a better range checker. It now checks range
638 (successfully) on integral operations [+-] (signed and
639 unsigned) for any C sized type. Still does not work well
641 int_in_size() returns an integer that is coerced to fit into
642 specified number of bytes.
644 Mon Jul 1 13:04:14 EDT 1991
646 language.[ch] Added the function binop_result_type(), which returns the
647 builtin (struct type *) type that would be the result of a
648 binop on the two values V1 and V2.
650 Wed Jul 3 19:22:53 EDT 1991
652 source.c Extended source_info() to include the source language in
653 the output from "info source".
655 Fri Jul 5 13:48:52 EDT 1991
657 utils.c Moved the support functions for the GDB set/show commands
658 dealing with language into language.c.
659 language.c Added the function language_info(), which displays info
660 about the current working language, type and range check
661 settings. Called via the GDB command "info language".
662 Added an initialization routine _initialize_language(),
663 that sets defaults for the language, type and range
664 variables and sets up the new GDB commands.
665 main.c Language setup moved to language.c.
668 Mon Jul 8 10:10:22 EDT 1991
670 valarith.c Debugged the range checker for arithmetic. Still does not
671 work for multiplication very well.
673 Mon Jul 8 12:40:37 EDT 1991
675 language.[ch] Added the function value_true() which returns non-zero if
676 its argument represents a boolean true value.
677 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
678 check the truth of an expression.
680 Thu Jul 11 12:51:34 EDT 1991
682 language.[ch] Added the predicate structured_type(), which returns
683 non-zero if the argument is a structured type.
684 Added the predicate pointer_type(), which returns non-zero
685 if the argument is a pointer type.
686 eval.c Added the ability to do addition and substraction on
687 pointers and integers. This case simply bypasses the
690 Thu Jul 11 14:41:42 EDT 1991
693 Added the symbol N_DEFD (0x4a) which is a definition
694 module dependency that is used by the GNU Modula-2
695 compiler and the linker. It is not important to GDB,
696 except that [dbx|coff|mips]read.c should ignore these
699 Fri Jul 12 16:07:00 EDT 1991
701 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
702 0 in val_print(). Also added statements to the else part
703 to coerce type (argument to val_print) to a pointer type
704 if it is an "array of unspecified length".
705 valops.c Added the function value_m2_string(), which returns a
706 (value) value which is a constant string, whose type is
707 (ARRAY [0..n] OF CHAR). The length field of the type
708 structure is set to zero, so it will be interpreted as an
709 "array of unspecified length".
710 stack.c Moved the language/frame mismatch check to
711 main.c:execute_command().
712 main.c The working language is recorded each time
713 execute_command() is executed. If working lang has
714 changed during its execution, then the new
715 language/type/range info is printed out for the user. If
716 the working language does not match the language of the
717 frame, a warning is issued.
719 Sat Jul 13 16:16:39 EDT 1991
721 eval.c Moved all the type-checking stuff for operators to
722 language.[ch] language.c. This is so we can keep language-specific
723 stuff (like for what type operators are defined) in
725 language.[ch] Added the function binop_type_check(), which checks to see
726 if its two (value) arguments are type-compatible with its
727 opcode argument. The opcode should represent an operation
728 involving an operator. Also added the macro function
729 unop_type_check, which calls binop_type_check with a
730 NULL second argument.
731 expprint.c Added Modula-2 operators to the op_print_tab, so info
732 expression.h break works correctly. Also added "op_string", which
733 returns the string corresponding to the (enum exp_opcode)
734 opcode that is its argument.
737 Sat Jul 13 18:26:18 EDT 1991
739 coffread.c Added code to record the type of function arguments with
740 each paricular function. Code is very similar to that
742 dbxread.c Moved add_param_to_type() to symtab.c
743 symtab.[ch] Added function add_param_to_type() from dbxread.c
745 *** NOTE: The above additions have not been tested.
747 Mon Jul 15 12:50:47 EDT 1991
749 langauge.[ch] Added the functions type_error and range_error, which work
750 like error() except if the type/range mode is set to
751 *_mode_warn, then they do not do a return_to_top_level(),
752 but merely print a warning.
753 Also changed [set|show]_[type|range]_command() to support
754 the new "warn" feature.
756 Thu Jul 18 17:50:54 EDT 1991
758 mipsread.c Added code to record the type of function arguments with
759 each particular function. Code is very similar to that
762 *** NOTE: The above additions have not been tested.
764 Fri Jul 19 11:19:10 EDT 1991
766 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
767 UMIN_OF_SIZE, which when given a size of a numeric type,
768 return the maximum and minimum value it can hold. UMAX...
769 and UMIN... return the result for unsigned types.
770 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
771 struct types. They call above macros.
772 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
773 avoid a name conlict with the above.
774 c-exp.y Added range checking on numeric constants in
775 parse_number() for completeness.
776 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
777 return 0 if working_lang is not language_c.
779 Thu Aug 8 14:17:22 EDT 1991
783 breakpoint.c Documentation strings of some commands changed to
784 eliminate the references to the C language where
787 Tue Aug 13 15:48:03 EDT 1991
789 m2-exp.y Added qualified identifiers to the grammar. The semantics
790 are slightly different from those of the GDB operator ::
792 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
793 type_exp, where type_exp is any valid type expression.
795 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
796 printcmd.c Modified ptype_command() so it actually parses the input
797 (necessary for type expressions with scope qualifiers).
798 Added the function ptype_eval() which expects an
799 expression composed of one OP_TYPE element.
800 *.[ch] Replaced all occurences of parse_c_expression with
802 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
804 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
806 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
808 Small fixes from Peter Schauer:
810 * infrun.c (child_attach): Lint.
811 * solib.c (find_solib): Handle shared libs version 2.
813 Small fixes from David Wood:
815 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
819 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
820 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
822 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
823 chars_per_line is at maximum (user typed `set width 0'). Fix
824 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
826 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
828 * coredep.c: include ptrace.h where necessary.
829 * mipsread.c(parse_lines): fix unsigned char problem that was
830 messing up line numbers on SGI's and possibly other MIPS based
832 * infrun.c (child_create_inferior): use better test to check
833 return val from setpgrp().
834 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
835 for sgi/irix support.
837 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
839 * mipsread.c (parse_symbol): Put non-static procedures
842 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
844 Patch together `text_start' and `text_end' for 29K port.
846 * exec.c (exec_command): If NEED_TEXT_START_END, define the
847 variables and set them based on the exec file.
848 * am29k-tdep.c: declare text_start.
849 * valops.c (call_function_by_hand): declare text_end.
851 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
852 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
853 because machines that do this will also have to know to
854 set NEED_TEXT_START_END. Besides, it was a redundant way to
856 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
857 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
860 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
862 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
864 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
865 Pass MUNCH_DEFINE to munch whenever we run it.
866 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
867 format string; use 0x%x instead.
868 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
869 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
870 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
871 * inflow.c: Handle `short' process group IDs.
872 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
873 and check for ptrace errors.
874 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
875 (coff_symfile_init): Initialize text_bfd_scnum.
876 (read_coff_symtab): Use it to find the text [and absolute?] sections.
877 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
878 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
879 Merge target arm case with other "easy" cases. Add target
880 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
881 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
883 * minimon.h, remote-adapt.c, remote-mm.c: Add.
884 * munch: Cope with RT/PC putting fns in data segment.
885 Restore ability to override `nm' by specifying MUNCH_NM.
886 * xconfig/rtbsd, xconfig/ultra3: New host systems.
887 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
888 and remote-adapt. Remove encapsulated coff #define's (the
889 support should go in BFD, and gdb shouldn't know or care).
890 * tconfig/a29k-kern: Same, but for remote kernel debugging.
891 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
892 * tm-29k.h: Update BADMAG (though it should go away).
893 Allow the register definitions to be overridden in another
894 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
895 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
896 DUMMY_SAVE_GR96, for handling kernel calling conventions
897 that use GR64+ rather than GR96+.
898 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
899 remote debugging of Ultra3 kernel. Includes tm-29k.h and
900 overrides various things.
902 * remote-mm.c (mm_attach, mm_wait): Handle attach like
903 child_attach does, making a clean stop in the newly attached
907 * coffread.c: Make coffread independent of any particular
908 variant of COFF. Avoid #include-ing any particular one except
909 internalcoff.h. BFD now passes key values for symbol reading
910 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
911 and the symbol masks and shifts); use them.
912 Remove obsolete end_of_text_addr.
914 * exec.c: Remove unused include files.
916 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
918 * Makefile.in (documentation targets): Pass $(M4).
919 Bugfix from eggert@twinsun.com (Paul Eggert).
921 * stack.c (down_silently_command): Check for stack existence.
923 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
925 * Makefile.in (VERSION): Update to 4.0.3.
927 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
929 * core.c (core_file_command): Print frame at coredump with
930 its level number, by calling print_stack_frame.
931 * frame.h: Add selected_frame_level, print_stack_frame.
932 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
933 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
934 Change print_sel_frame and print_selected_frame callers to
937 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
938 * symfile.c (free_named_symtabs): Ditto.
939 * main.c (main): wrap_here needs an arg.
940 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
941 (solib_add): Avoid noise.
942 (solib_create_inferior_hook): Lint.
943 (sharedlibrary_command): Move dont_repeat to here.
944 * utils.c (error): Call wrap_here to force buffered output.
946 Small patches from Peter Schauer:
948 * coffread.c (start_symtab): Free any existing line_vector before
950 (read_coff_symtab): Ditto for type_vector.
952 * source.c (lines_to_list): New variable, replacing function.
953 (all uses): Use as variable.
954 (_initialize_source): Add 'set listsize' and 'show listsize'.
955 * utils.c (lines_to_list): Remove function.
956 * stack.c (print_frame_info): Use as variable.
957 * defs.h (lines_to_list): Remove declaration.
959 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
961 * breakpoint.c (insert_breakpoints): Restore warning about
962 the program might be running in another process, but only for
963 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
964 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
966 * utils.c (error): if error_pre_print is set, print the string
968 * main.c (main, print_gnu_advertisement, print_gdb_version):
969 Reformat legalese so it always prints, but acts as an "I'm here"
970 message while symbols are being read. If any errors occur,
971 print a few newlines to set off the message and start it at the
972 left margin. Remove mention of "help" command, and don't yak
973 about symbol reading.
974 (catch_errors): Error string is now printed first in case of
976 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
977 suggest the "help" command.
979 * Makefile.in (VERSION): Set to 4.0.2.
981 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
983 * .gdbinit: Remove useless "rr" command. Set complaints
984 to 1 for people debugging gdb.
986 * breakpoint.c, remote-vx.c: Reword strings printed by
987 catch_errors callers.
989 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
991 * WHATS.NEW: "history write -> history save". Doc "write on/off".
992 (Fix from kenc@viewlogic.com.)
994 Fix some infrastructure to be able to cope with host and target
995 machines with different sized basic types (ints, ptrs, etc).
996 (Idea from pierre@la.tce.com (Pierre Willard).)
998 * values.c (value_from_longest): Rename from value_from_long.
999 Handle pointer types as well as integers, so that targets with
1000 different pointer sizes from the host can be accomodated.
1001 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1002 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1003 uses of value_from_long to value_from_longest.
1004 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1005 the correct pointer type to value_from_long{est}.
1007 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1009 * remote-vx.c: Remove obsolete code for calling functions via
1010 vxworks kludge interface (it referenced value_from_long).
1012 * valops.c (value_string): Find malloc with lookup_misc_func, not
1015 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1017 Make writing to files work properly. (Fixes to BFD are also needed.)
1019 * core.c (core_open): Open file ourselves, read or r/w, depending on
1020 write_files. Use bfd_fdopenr.
1021 * gdbcore.h (write_files): New variable.
1022 * exec.c (write_files): Define variable, add set&show for it.
1023 (exec_file_command): Use write_files to open for read or r/write.
1025 Make shared library reading happen automatically. These changes
1026 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1028 * inferior.h (stop_soon_quietly): Add to exported variables.
1029 * infrun.c (child_create_inferior): call solib hook, if defined.
1030 (child_attach): call solib hook, if defined.
1031 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1032 (find_solib): Use lookup_misc_func rather than hand-rolled.
1033 (symbol_add_stub): New stub for catch_errors.
1034 (solib_add): Avoid output if !from_tty. Catch errors rather
1035 than just calling symbol_file_add and bombing.
1036 (solib_create_inferior_hook): Interface with the target process
1037 to let it read and alloc shared libs, then figure out what it did.
1039 * core.c (validate_files): Fix typo, soften warning.
1040 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1042 * utils.c (fputs_demangled): Avoid duplicate printing if
1043 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1045 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1046 (Fix from pierre@la.tce.com (Pierre Willard).)
1048 * main.c (catch_errors): Change argument to a char * from an int,
1049 since a char * can point to a struct full of glop, but an int
1050 is not guaranteed to be able to hold a pointer.
1051 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1052 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1053 * core.c (core_open, solib_add_stub): Adapt.
1054 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1056 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1058 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1059 by adding .NOEXPORT target.
1061 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1065 * Makefile.in (VERSION): Roll to 4.0.
1066 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1068 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1070 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1073 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1076 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1078 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1079 reflect above name change
1081 * WHATS.NEW: correct pointer to refcard.
1083 * doc/gdb.texinfo: update New Features, Installing
1085 * doc/gdbint.texinfo: add short description of configure +template
1087 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1089 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1091 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1093 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1094 tar file, add dependencies for referenced doc files.
1096 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1098 * coffread.c, symfile.c, stack.c: saberized.
1100 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1102 * doc/refcard.tex: permuted Essential Commands sec
1104 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1106 set/show symbol-reloading
1107 default set complaints 0
1109 RET-repeat disabled after prompted long displays
1110 processID (attach) interpretation of 2nd GDB cmdline arg
1112 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1114 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1115 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1116 breakpoint.c, main.c: lint.
1118 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1120 Install new configuration scheme for GDB and friends.
1122 * config.sub: Translate ordinary names to three-part names.
1123 * configure: Use three-part names internally.
1124 * configure.in: Translate three-part names to filenames.
1126 * README, WHATS.NEW: Update for gdb-4.0.
1127 * Makefile.in: Roll VERSION to 3.99.
1129 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1131 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1132 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1133 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1134 to single structures rather than arrays; when passing
1135 their address, use &. This avoids trouble with bdead compilers.
1136 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1137 instead. This avoids portability headaches.
1138 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1140 * source.c (open_source_file): Avoid ANSI const bdeath by
1141 skipping declaration and then casting result value.
1142 * tm-hp300bsd.h: Clarify comment.
1143 * utils.c (strstr): Result is const char *; ANSI bdeath.
1144 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1145 since system include file defines it differently from "defs.h",
1146 though the two are equivalent for our purposes.
1147 * tconfig/hp300bsd: Add m68k-tdep.o.
1149 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1151 * tconfig/sun*4: Remove warnings about system assembler.
1153 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1155 * mcheck.c: Avoid warning about undeclared abort fn.
1156 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1157 it causes recursive calls to error() when used in cleanups.
1158 To do so requires that we make it a function, so we do.
1159 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1160 * utils.c (do_cleanups): Remove the current cleanup from the
1161 chain *before* calling it, in case error() is called from it.
1162 The result won't be pretty, but won't be an infinite loop either.
1164 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1166 * dbxread.c (read_struct_type): Grok anon structs for C++.
1167 (vb_name, vptr_name): Null terminate these strings.
1169 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1171 Minor bug fixes from BSD Net2 gdb:
1173 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1174 returns 0, there is no previous frame.
1175 * breakpoint.c (commands_command): If !from_tty, don't call
1176 input_from_terminal_p().
1177 * dbxread.c (record_misc_function): Speed up slightly.
1178 (compare_psymbols): Ditto.
1179 * infcmd.c (do_registers_info): Take a second argument to
1180 determine whether to print float registers. "info registers"
1181 does not do so anymore. "info all-registers" does, now.
1182 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1184 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1185 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1189 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1190 executing_breakpoint_commands if we are interrupted by error.
1191 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1192 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1193 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1194 catch_errors() so we can setup the frame regardless of whether
1195 the shared libs work.
1196 * ieee-float.c (double_to_ieee_extended): Get exponent from
1197 right place in little-endian systems. From John Carey.
1199 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1201 * main.c: Remove unused terminating_signals and catch_termination().
1202 (long_options): Terminate with a zero element.
1203 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1204 (gdb_readline): Make call-compatible with readline.
1205 (init_signals): Improve comments re vfork vs. signal.
1207 * utils.c (prompt_for_continue): Use new gdb_readline().
1208 If we prompt for continuation, we don't let CR repeat the previous
1209 command, once we get back to a prompt. It's too easy to keep
1210 hitting CR, expecting "--more--" prompts, and have some long
1211 command start repeating on you.
1213 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1215 * blockframe.c (frameless_look_for_prologue): Speed up by
1216 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1217 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1218 Define two variants, one faster.
1219 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1220 and return zero, rather than giving an error.
1221 (setup_arbitrary_frame): Initialize the PC in the new frame.
1222 (skip_prologue): Add a second arg saying whether we're just
1223 checking for a frameless function or not.
1225 * core.c (core_open, core_close, core_xfer_memory): Move
1226 section table pointers and bfd* into the target_ops.
1227 (core_open): Allow errors in shared lib reading, etc.
1228 (core_files_info): Describe shared library sections.
1230 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1231 exec_files_info, set_section_command): Move section table
1232 pointers and bfd* into the target_ops.
1233 (add_to_section_table): Add BFD to section table.
1235 * target.c (target_xfer_memory, target_info): Pass target to
1236 xfer_memory and target_info functions.
1239 * gdbcore.h: Move struct section_table.
1240 * target.h: New home of struct section_table.
1242 * solib.c (solib_add): New argument is the target_ops whose
1243 section list is to be added to, if any. Reallocate the
1244 sections in that target to add any that come from shared libs.
1245 (throughout) so_sections renamed to sections.
1246 (solib_xfer_memory): Deleted.
1247 * tm-sunos.h (SOLIB_ADD): Add target argument.
1248 (SOLIB_XFER_MEMORY): Delete.
1250 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1251 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1252 from target_ops. It's the same on all targets. Add two section
1253 pointers to target_ops.
1255 * stack.c (find_relative_frame): Dump ancient algorithm for
1256 "down", just use handy "next" pointers.
1257 (frame_command): Don't error if there is no stack; let user
1260 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1261 modifies static state in the parent process; new_tty itself
1262 runs in the child and modifies the child's file descriptors
1263 to match the saved static state.
1264 * infrun.c (child_create_inferior): Call new_tty_prefork,
1267 * infptrace.c (child_xfer_memory): Add ignored target arg.
1268 * remote-eb.c (eb_xfer_inferior_memory): ''
1269 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1270 * remote-vx.c (vx_xfer_memory): ''
1271 * remote.c (remote_xfer_memory): ''. Rename from
1272 remote_xfer_inferior_memory.
1274 * main.c (main): Only try to attach "corefile" argument if
1275 it starts with a digit.
1277 * symfile.c (symbol_reloading): New "set/show" variable.
1278 (symbol_file_add): Shorten message about symbol reading.
1279 (add_symbol_file_command): Merge with add_syms_addr_command,
1280 since this should work on all targets now.
1281 (stop_whining): Default to zero, to shut up complaints
1282 about bad symbol tables on many systems.
1283 (free_named_symtabs): Just exit unless symbol_reloading.
1285 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1286 and add comment explaining shared library screw.
1288 * source.c: #if defined => #ifdef.
1290 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1292 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1294 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1296 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1297 (doc/Makefile knows how to make one for local config)
1299 * Makefile.in: use doc/Makefile for doc targets
1301 * doc/Makefile: GDB documentation now has its own Makefile
1302 doc/refcard.tex: renamed from "gdbrc.tex"
1303 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1304 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1307 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1309 * values.c (baseclass_addr): When reading target memory, use the
1310 length of the basetype, not the upper type. We've only malloc'd
1311 enough space for the basetype, leading to errors in free().
1313 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1314 ends up as a function specially, since we know the actual type of
1315 the pointed-to address. This (somewhat) fixes display of
1316 expressions that include misc_function_vector names. Try `cond 1
1317 !strcmp("a","b")' then `i b'.
1319 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1320 The child can be proceeded from inside wait_for_inferior in
1321 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1322 getting skipped in that case.
1324 * expprint.c (print_subexp): Use filtered output, since the
1325 subroutines we call use it, otherwise the output is horribly
1326 mangled, since output of wrappable stuff comes out late.
1328 * Makefile.in: Bump VERSION to 3.98.1
1330 * infrun.c (child_create_process): Use execlp to find the
1331 shell to exec our target program. This requires some fiddling
1332 with `environ' since there is no execlpe().
1334 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1336 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1337 Minor rearrangement of refcard permits two new make targets--
1338 gdbrc.dvi DVI output for refcard, using CM fonts
1339 gdbrc.ps PostScript refcard, using PS fonts
1341 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1345 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1346 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1348 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1350 * doc/gdb.texinfo: last changes for release.
1351 Minor typo and formatting fixes; incorporated most fixes remaining from
1352 filed mail commenting on earlier drafts.
1354 Added warnings: pipes don't work in run command;
1355 conditions are converse of assertions;
1356 step over fn without debug info goes to next fn;
1357 vars may have "wrong" values near fn entrance, exit
1359 Added example from Kingston on printing repeated nonadjacent values
1361 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1362 shell mode for signals
1364 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1365 doesn't sound so much like its parent "Stopping and Continuing"; also
1366 moved entries on continue to top of section, so they don't get lost.
1368 Improved installation directions in appendix, added manual formatting
1371 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1373 * configure.in: Remove xm.h and tm.h even if we aren't linking
1374 new ones, so "./configure sun4; ./configure none" does the right
1375 thing. Assume that alldeps.mak and depend are already built in
1376 srcdir, and avoid running "make" (particularly "make depend",
1377 which involves "gcc") from inside configure. Build Makefile
1378 directly rather than building Makefile.conf first.
1379 * configure: Regenerate with above changes.
1380 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1381 to 3.98. Revise gdb.tar.Z procedure to produce a file
1382 called gdb-$(VERSION).tar.Z but which unpacks into a
1383 directory called "gdb". Move non-source files out of
1384 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1385 (depend): Don't try to do "gcc expread.y".
1386 (expread.o): Update dependencies by hand.
1388 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1391 Fixed a variety of small typos that prevented info from formatting
1392 cleanly; altered too-long heading for GPL Appendix, as discussed
1393 w/RMS; Changed date on cover to July 91.
1395 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1398 (1) Applied some fixes due to comments from Larry Breed (easier ones
1399 through chapsec 5.2)
1400 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1401 it's broken in latest texinfo
1402 (3) Introduced *some* use of [] for optional arguments, where
1403 explanation is not simpler by listing cmd w arg and cmd w/out arg
1404 separately. Still not using @deffn.
1405 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1406 couple of headings are too long. Need patches to texinfo or revision
1409 * Partial update to README (which still needs work for this
1410 release!): (1) use of configure corrected for new script,
1411 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1413 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1415 * symtab.c (lookup_symbol): Don't complain right off about
1416 no debug symbols; use the misc function vector first.
1417 (list_symbols): Use misc function vector to find symbols
1418 that don't have debug info, and print them.
1419 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1420 PC range doesn't match symtab PC range, as it does on the
1421 MIPS because our symtab reading isn't perfect.
1423 * dbxread.c (dbx_symfile_read): Make warning about
1424 "no debug symbols" slightly nicer.
1426 * source.c (select_source_symtab): If "main" symbol exists,
1427 but decode_line_spec can't find line info, don't just return
1428 a zero; try other source symtabs or give an error.
1430 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1431 their low addresses first, then rip through fixing high addrs.
1433 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1434 <runene@ifi.uio.no>.
1435 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1437 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1439 * Minor, mostly mechanical, cleanup of doc subdir for clean
1440 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1441 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1443 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
1445 Mostly MIPS and general symbol-reading fixups.
1447 * doc/gdbint.texinfo: Add documentation on symbol-reading
1450 * mipsread.c: Remove kludges around #include "ecoff.h".
1451 Remove redefinitions of a_magic, etc, no longer used.
1452 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
1453 Fix global overview comments to match symfile.c protocol.
1454 (mipscoff_new_init): Eliminate cur_hdr if we have one.
1455 (mipscoff_symfile_read): Eliminate unused code. Avoid
1456 sorting all the symtabs, when all we have read here is psymtabs.
1457 The symtabs are sorted as they are created anyway. Tell
1458 condense_misc_bunches whether we're mainline.
1459 (psymtab_to_symtab_1): Pass filename when recursing, to make
1460 stack trace more informative.
1461 (parse_partial_symbols): Assume cur_hdr as argument.
1462 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
1463 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
1464 the TYPE_NAME of char *, since that's done in symfile.c.
1465 (free_numargs, parse_symbol, add_symbol, add_block,
1466 shrink_linetable): Declare these fns void.
1467 (upgrade_type): Convert tree of if's to switch. Clean up
1468 bogus "off == 0" handling with a complaint. Avoid setting
1469 field bitpos and bitsize of array with lower and upper bounds.
1470 Check specified bitsize of elements against their actual type's
1471 bitsize, and complain if different. Complain about unknown
1473 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
1474 (psymtab_to_symtab_1): Print names of subsidiary files that
1475 are being read in. FIXME, we read far too many files. This code
1476 is not the problem, the problem is in parse_fdr where the psymtabs
1478 (cross_ref): Result should indicate that we used one aux entry
1479 normally, or two if we encountered a "next" entry. This used
1480 to leave the caller pointing at the wrong aux entry.
1481 (add_symbol): If overflowed cur_block, reallocate it larger,
1482 chase all pointers to it, and complain(), rather than clobber memory.
1483 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
1484 (new_field): Only allocate one field initially, not two.
1485 Pull ++ out of macro argument. Simplify.
1486 (_initialize_mipsread): Avoid initialization of importd
1487 global_psymbols and static_psymbols.
1489 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
1490 to properly set pst->symtab; avoid searching for it.
1491 (symfile_fns): Improve comments, add a FIXME.
1492 * dbxread.c: Update comments to reflect symfile protocol.
1493 (read_ofile_symtab, end_symtab): Return the symtab.
1494 (psymtab_to_symtab_1): Set pst->symtab.
1496 * coffread.c (coff_symfile_read): tell condense_misc_bunches
1497 whether we're mainline.
1499 * symfile.h (sym_fns): Remove unused sym_discard member.
1500 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
1502 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
1503 the environment variable is not.
1504 * infcmd.c (finish_command): Use filtered printfs.
1505 * cplus-dem.c: Add struct tags to a few unnamed structs.
1506 * valops.c (value_coerce_array): Improve comments.
1507 * valprint.c (type_print_varspec_suffix): Print array size only
1508 if greater than zero.
1509 * m88k-tdep.c: Shift some lines left by one space, that had
1510 apparently been trashed at some point.
1511 * TODO: More things to do, a few got done.
1513 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1515 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
1516 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
1518 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
1519 * expread.y, findvar.c, symmisc.c: Ditto.
1520 * printcmd.c (address_info): Update printed forms of LOC_
1521 symbols. Elim LOC_EXTERNAL.
1522 (print_frame_args): Keep track of param stack offsets before
1523 re-looking up to find the local register param is kept in.
1525 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
1526 Further integration of mipsread into gdb. Eliminate unused
1527 routines, duplicate declarations. Handle static symbols in
1528 psymtabs as well as external symbols. When reading symtabs,
1529 insert symbols into the correct block (global, static, or a local
1531 (read_mips_symtab, parse_partial_symbols): Don't pass useless
1533 (mipscoff_symfile_read): Don't call select_source_symtab.
1534 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
1535 rather than SYMBOL_VALUE.
1536 (parse_external): Comment clobbering of top_stack.
1537 (parse_partial_symbols): Update comments. Allocate and parse
1538 static symbols as well as external symbols. FIXME, enum values
1539 are not handled in this pass, but should be. Inline new_psymbol.
1540 Use SYMBOL_VALUE_ADDRESS.
1541 (psymtab_to_symtab_1): Read symbols into global static block
1542 by default (until enter some function's local block context).
1543 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
1544 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
1546 * source.c (select_source_symtab): Select a source symtab
1547 from either the symtabs or, failing that, the psymtabs.
1548 (list_command): Update error message.
1549 (forward_search_command, reverse_search_command): Use getc, not
1550 fgetc, for speed. FIXME, add comment about buffers that die if
1551 overrun by long line.
1553 * values.c (unpack_field_as_long, modify_field): Avoid shifting
1554 by an entire word, which is not portable, if we have a 32-bit
1555 field. (Code in dbxread.c already turns such bitfields, if
1556 aligned, into ordinary ints, but fixing this will help for other
1557 symbol formats and for future changes.)
1558 * core.c (core_open): Handle ANSI const brain death.
1559 * utils.c (vprintf): Fix varargs typo.
1561 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1563 * findvar.c (find_var_value): Handle &function better.
1564 * TODO: Document work needed on &fn and &array.
1565 * printcmd.c (print_address_symbolic): New arg is the prefix
1566 to print if a name is printed.
1567 (print_address_demangle): Honor "set print address" now.
1568 Use new arg above to improve spacing of output.
1569 * valprint.c (val_print): When printing function pointers,
1570 print symbolic form too.
1571 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
1573 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1575 * core.c (memory_error): Reword error msg to mislead less.
1577 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
1579 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
1580 parse_partial_symbols): Use newer BFD internals (external_filehdr
1581 and external_aouthdr), byte-swap the fields that we care about
1582 before using them, and make the file header data local to
1583 read_the_mips_symtab rather than global.
1585 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
1587 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
1588 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
1590 * main.c (command_line_input): Flush stdout and stderr
1591 before every call to readline. This reportedly fixes a bug
1592 that comes up in Sys V running emacs-gdb and/or xxgdb,
1593 when stdin/out are pipes or sockets.
1595 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1597 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
1598 Avoid declaring Makefile dependencies, because GNU Make stupidly
1599 tries to update it if we do.
1601 * coffread.c: Revise for minor changes to bfd internal coff
1604 * configure: If -template= is given a relative path, make it
1605 absolute before recurring in subdirectories.
1607 * configure, configure.in, Makefile.in: Install "configure" script
1608 as replacement for config.gdb.
1609 * config.gdb, Makefile.dist, Makefile.sdir: Remove
1610 * README: Update for configure, mostly. FIXME.
1612 * Add dec3100 as equivalent to littlemips. Indicate in all host &
1613 target config files that they are for the host. When the lines
1614 get copied into the Makefile, this makes it more obvious what's
1617 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1619 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
1620 tabs, which end up in the disassembler output inadvertently.
1622 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1624 Make it compile cleanly in an ANSI GCC2 environment.
1626 * blockframe.c: <stdio.h>
1627 * cplus-dem.c: free takes a void *, ifdef __STDC__
1628 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
1630 * defs.h (alloca): Avoid doing anything if alloca already def'd.
1631 * stddef.h, stdlib.h: Remove these files.
1632 * symtab.c: Avoid declaring qsort, close.
1633 * symfile.c: Avoid declaring close.
1634 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
1635 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
1637 Assorted other changes.
1638 * dbxread.c: include "libaout.h", not "liba.out.h".
1639 * printcmd.c (print_frame_args): Set recurse properly for
1640 indentation of struct and array parameters.
1641 * valops.c (value_cast): Allow cast to void.
1642 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
1643 single_step() in a target-independent fashion.
1644 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
1645 set up to be ready to continue. This makes us target independent.
1646 * infptrace.c (child_resume): Remove call to single_step; now
1647 can single step a SPARC target of any kind.
1649 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1651 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
1652 docn into separate sections---basically chapters, plus two loose
1653 pieces that can be configured to go in different places. This
1654 allows GNU m4 to preprocess the manual without coredumping.
1656 * Makefile.dist: tell TeX where to find texinfo.
1658 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1660 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
1661 the new target "rdl-apps.texinfo" which captures the Makefile
1662 variable that records where to find the Readline libraries.
1664 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
1666 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
1667 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
1668 * defs.h (const, volatile): Only define if not already defined.
1669 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
1671 * README: Update for release 3.95.
1672 * config.gdb: Don't create readline dir in subdir builds.
1673 * main.c: Include with "..." form for non-system include files,
1674 so "gcc -MM" for "make depend" works.
1675 Include readline files with "...h" rather than <readline/...h>.
1676 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
1678 * coffread.c: Undo minor damage done by Rich Pixley. Use
1679 different internal and external representations of COFF
1680 data structures. Use new BFD routines for swapping them in and
1682 * symfile.c (free_named_symtabs): Avoid freeing file names that
1683 are null or empty. Old i960 tools seem to produce files that
1684 claim to have empty names, causing each successive file read
1685 to blow away the previous one.
1686 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
1687 Move deferred_stores to top of file, but don't separate its
1688 #define's from its variable. Add commentary.
1689 * Makefile.dist: Fix Rich damage; undo "configure" changes in
1690 favor of keeping the (working) config.gdb. Move readline
1693 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
1695 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
1697 * infptrace.c (fetch_registers): no result, since now void.
1698 * tconfig/news: target depends on m68k-tdep too.
1700 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1702 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
1705 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
1706 applied various small fixes due to or inspired by RMS comments
1708 * doc/gdb.texinfo: finished using all RMS comments, save those for
1709 appendices on readline and cmd history (which are in other source
1712 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1714 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
1715 chapter 9; (2) documented 'break' command's menu mode for
1716 overloaded names, in response to hgs problem report C++ p-31
1718 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1720 * doc/gdb.texinfo: (1) better introductory example; (2) more
1721 consistent use of @code, @samp, @file, @kbd throughout; small
1722 cleanups to first three nodes; (3) new "Contributors" node;
1723 (4) Appendix, Renamed Commands; (5) divert specialized startup
1724 instructions to "Targets" chapter for generic manuals, while
1725 leaving them up front for manuals specific to specialized
1726 environments; (6) apply fixes from RMS comments through chapter 4.
1728 * pretex.m4: modify explanatory text slightly (and redefine
1729 "regexp") to keep GNU m4 from complaining. (It still crashes
1730 later, but one step at a time...)
1732 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
1734 * readline/readline.c (update_line): Avoid dereferencing a pointer
1735 before comparing it to its bounds. Saber caught this.
1736 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
1737 and only set PC if tgetstr returned non-null. Saber caught this.
1739 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1741 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
1742 stuff for config manual) here where it counts; updated
1743 to use new subdir structure (gdb/doc/).
1745 * Makefile: generated from above via
1749 * gdbint.texinfo: added instructions on generating gdb.info* files
1750 locally for release. These are ordinary info
1751 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
1752 Makefile)---but due to use of texinfo 2, can't count on makeinfo
1753 to generate these, so we distribute them already formatted.
1755 * gdb.texinfo: included full Info node and menu crud (as generated
1756 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
1758 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
1759 put in comments-for-future gdb.info target (one day makeinfo will
1762 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1764 * gdb.texinfo: Updated to include new or old undocumented
1765 commands, at least the following (perhaps some others I forgot to
1766 record): info f, info float, info path, info program, info s, info
1767 set, info source, info terminal, info types, info user, set/show
1769 Also covered all recent GDB command renames for v4.
1771 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1773 * mipsread.c: Rather than keeping count of how many symtabs
1774 and psymtabs we have, for sorting purposes, count them when
1775 we need to sort. This fixes bug in rereading of symbol tables.
1777 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1779 * infcmd.c: renamed "info path" to "show paths"

1790 Fix up "saber_gdb" to work again.
1791 * saber.suppress: Update.
1793 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
1794 symtab.h, target.c, target.h: Lint.
1795 * core.c: setup and select frame after reading shared libs,
1796 else reading shared libs will clobber them. Lint.
1797 * utils.c (error): Force out any buffered wrap text.
1799 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1801 * remote.c: Remove decls of memory_insert_breakpoint
1802 and memory_remove_breakpoint, no longer used. (Suggestion of
1805 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
1806 to make it easier to interface to "configure"'d libraries.
1808 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
1810 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
1811 aliases for set/show print.

1867 * coffread.c [TDESC]: Move setting of debug_info from
1868 coff_symfile_read to find_linenos and make it work with BFD.

1872 * signame.c: Cast const char* to char* when assigning to sys_siglist.
1874 * utils.c (strsave): Make arg const char* not char*.
1876 * infrun.c (wait_for_inferior) [SHIFT_INSN_REGS]: Use

1897 Mips bringup and general cleanup
1899 * cplus-dem.c: Move CPLUS_MARKER define to after defs.h.
1900 * infptrace.c (PT_WRITE_D, PT_READ_D): Use correct values.
1901 (This still doesn't seem to make MIPS bkpts work.)

1909 enums appropriately.
1911 Wed May 1 14:10:22 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

1920 can have both ints and enum type_pieces in it.
1921 ({push,pop}_type_int): New functions.
1923 Tue Apr 30 13:18:58 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

1935 symtab.c, cplus-dem.c, value.h, expread.y, valprint.c,
1936 copying.awk, solib.c, inflow.c, symmisc.c
1937 : Lint. Use read_memory not read_memory_integer on CORE_ADDR's.
1938 Use {value_as,unpack}_pointer (added to values.c)
1939 not {value_as,unpack}_long on CORE_ADDR's.
1940 Use longest_to_int (added to defs.h) instead of cast to int.
1941 Remove from_tty arg to mod_path.
1942 Put symfile_bfd in {coff,dbx}read.c not symfile.h.
1943 Use OP_NULL instead of 0 where dummy enum exp_opcode needed.

2444 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
2445 * expprint.c (print_subexp): Avoid switch fallthru on
2446 BINOP_ASSIGN_MODIFY, so we can print += and such.
2447 * frame.h: Fix typo.
2448 * inflow.c (kill_command): After killing inferior, print our
2449 current frame in the core file, if we have one.
2450 (generic_mourn_inferior): When inferior dies, either select
2451 the current frame (in the new target, e.g. core file), or
2452 set both the current and selected frames to NULL.
2454 Changes from Peter Schauer.
2456 * infptrace.c: Avoid <sys/ptrace.h> on USG.
2458 * Make all file names fit in 14 characters (sigh and damn!):

2469 * Makefile.dist, README, config.gdb, convex-pinsn.c,
2470 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
2471 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
2474 * command.c (user_info_1, user_info): New command for listing
2475 the user-defined commands.
2477 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2479 * dbxread.c (really_free_pendings): Clear file_symbols
2480 and global_symbols after freeing them; otherwise, running
2481 this function twice (if it appears twice on the cleanup
2482 chain), we try to free things twice.
2484 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
2485 based on text_addr (the address of text in core), not on addr (the
2486 offset between text in the .o file and in core). This change
2487 is from Peter Schauer.
2489 * main.c: Define ALL_CLEANUPS as a cast of zero.
2490 (return_to_top_level): Use it.
2491 (main): Do all cleanups after each command run as part
2492 of the gdb startup sequence. Also do all cleanups before
2493 entering the command loop, and every time we exit the command
2494 loop and reenter. Before, the cleanups from the startup sequence
2495 were being left undone until the first error!
2496 (command_loop): Rename do_nothing cleanup to command_loop_marker
2497 so we can see it easily when examining the cleanup chain.
2498 (init_signals): Add another do_nothing for signal handling.
2499 (quit_command): Only try to kill target if it has execution.
2500 Problems in the target stack got us into a state where
2501 inferior_pid was nonzero but none of the targets had execution.
2502 In this state you couldn't exit gdb.
2504 * dbxread.c: Two changes from Peter Schauer.
2505 (echo_command): Fflush output after an echo command.
2506 (show_history): Pass all args to cmd_show_list.
2508 * utils.c (init_malloc): Call mtrace to turn on tracing
2509 if the environment variable MALLOC_TRACE is set to a file name.
2510 * mtrace.c: Add source file which provides a log of every malloc,
2511 free, and realloc to a trace file.
2512 * mtrace.awk: Add source file which analyzes the trace file.
2513 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
2514 (VERSION): Roll to 3.94.3.
2516 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
2517 (check_duplicates): Don't bother with watchpoints.
2518 (set_raw_breakpoint): Comment about danger of this routine.
2519 (watch_command): Parse and eval all args before calling
2522 * solib.c (find_solib): Avoid error in referencing memory to
2523 see if any more shared libraries have been added. This is
2524 particularly useful if the target has terminated. Bug reported
2527 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
2528 in bringing up 3.94.2 on the Sun-3.
2530 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
2531 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
2532 expression (in scope) before reenabling watchpoint.
2533 * signame.c (init_sigs): Add missing declaration of i, fix
2534 sys_siglist declaration.
2535 * source.c (list_command): Fixed range computation to use
2537 * stack.c (backtrace_command): Do not allow command if target has
2538 no stack, print informative error message.
2539 * target.c (target_command): Do not write into command line
2540 because this fails if the target command is used in a user defined
2541 command. [This change was enhanced by gnu to support any-
2542 unique-prefix matching on target names.]
2543 * valops.c (value_struct_elt): Avoid infinite loop on an
2544 erroneous attempt to print the member of function (try p main.p).
2546 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2548 * expread.y (name_no_typename): Avoid reduce/reduce errors
2549 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
2550 Since the GDB parser really doesn't use name_no_typename in a
2551 name-only context, the parser can't tell the diff between
2552 names and numbers here. Avoid allowing a name_no_typename
2553 to be a NAME_OR_*INT to resolve the conflict.
2555 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2557 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
2559 * valprint.c (val_print_fields): bitfield printing didn't handle
2560 byte order. Indirect through a few more fns to cope.
2562 * values.c (modify_field): also cope with byte order.
2564 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2566 Cleanup for release 3.94.2:
2568 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
2569 include files. Roll version to 3.94.2.
2571 * coffread.c (init_stringtab): Read length into unsigned char
2572 array before swapping; don't assume 32-bit longs.
2574 * target.c (target_info): Don't bother with get_sym_file, just use
2575 the symfile global variable.
2576 * symtab.h, symfile.c (get_sym_file): Delete it.
2578 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
2579 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
2580 (read_type): Replace one more error() with complain().
2582 * mipsread.c (parse_partial_symbols): Replace printf with complain.
2584 * i960-tdep.c: Fix copyright attribution.
2586 * config.gdb: Quote all backquotes in doublequotes. You can
2587 quote me on that. BSD 4.4 shell found this one.
2589 * infptrace.c (throughout): The third argument to ptrace is an
2592 * infrun.c (wait_for_inferior): When program has terminated, we
2593 have to call target_terminal_ours before we pop that target off
2594 the stack (e.g. before a call to target_kill or
2595 target_mourn_inferior). This fixes problem where a program
2596 terminates, then GDB stops for (tty output) and you have to type
2597 "fg" to the shell to resume it. FIXME: This code for what to
2598 do after termination really should be in normal_stop instead.
2600 * gdbcore.h (read_memory_check): Change declaration; it changed
2603 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
2604 4.4 prereleases, this avoids a bug in their sgtty compatability
2606 * remote.c: Use terminal.h rather than hand-rolling the same.
2608 * signame.c, signame.h (psignal): Arg is unsigned, not int.
2609 * utils.c (strsave, strstr): Fix arg types.
2610 * valprint.c (val_print): lint
2612 MIPS symbol table support from Per Bothner:
2614 * symfile.c (symtab_fns): Remove initializer table that needs to
2615 be hacked for each new symbol file format supported.
2616 (add_symtab_fns): New function, chains symbol table
2617 handlers into the global list.
2618 (symfile_init): Search this list.
2619 * symfile.h: Add next pointer, declare add_symtab_fns.
2620 * coffread.c (_initialize_coffread): Call add_symtab_fns.
2621 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
2623 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
2624 symbol *). Thus, we no longer need the hack to trash
2625 pst->filename. Good, since that hack confused code in symfile.c!
2627 (reorder_symtabs, destroy_all_symtabs): Removed static
2628 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
2629 Instead, the latter now uses a temporary array (stack-allocated
2630 from an obstack, and then freed).
2632 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
2633 haven't been set in the outermost stBlock of a procedure. This was
2634 a problem with f77 binaries on Ultrix 4.?.
2636 (new_symtab, new_symbol, new_type): Continue changing code to use
2637 obstacks more and otherwise conform to dbxread internal style.
2638 Made the free_code of symtabs be free_linetable (as in dbxread)
2639 instead of free_contents. This implies memory leaks when reading
2640 a new symbol table, until the conversion is finished. Did change
2641 (struct symbol) and (struct type) to be allocated on the
2642 symbol_obstack. Blocks and blockvectors are among the things
2645 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
2646 tested much, but it solved one problem (reported by Meissner), and
2647 cleans up some other things. The problem happened when an
2648 included file contains actual code (functions) and not just
2649 definitions. The mips coff is a little inconvenient there, since
2650 it may cause a procedure to be mapped to the wrong psymtab.
2652 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
2653 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
2654 this will need work for the new core paradigm.
2656 Opcode patches from the net:
2658 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
2659 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
2660 missing altogether - they are added here. From Bruce Bauman.
2661 * mips-opcode.h: The low mask for C0 instructions was too small.
2662 From Garrett Lau. I modified the fix to check the entire 32-bit
2665 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
2668 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2670 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
2672 * dbxread.c (read_type): Pointer subtraction (value_sub in
2673 valarith.c) sometimes failed because the types of the
2674 pointers being subtracted were not identical.
2675 These differed because dbxread.c was allocating pointer types
2676 using dbx_alloc_type+smash_to_pointer_type instead of
2677 lookup_pointer_type. I failed to find a justification for the
2678 former, so I changed it to use the latter. Similarly, I
2679 replaced smash_to_function_type by lookup_function_type,
2680 and smash_to_reference_type by lookup_reference_type.
2682 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
2683 _initialize_mipsread): corresponding changes.
2685 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
2687 * source.c (mod_path): Do tilde_expand on each component of the path,
2688 rather than on the (list of) paths as a whole.
2689 (print_source_lines): Set first_line_listed in addition to
2690 current_source_symtab and current_source_line. If the source was
2691 not findable, after a "dir" command to fix the problem,
2692 a "list" would get the wrong lines.
2694 While I was there... (gnu):
2696 * dbxread.c (read_type): Change error to complaint.
2698 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2700 First attempt at detailed understanding of symbol table memory alloc.
2702 * dbxread.c (dbx_symfile_read): Free our string table if we
2703 aren't the mainline. Free the "info" struct since we're done with
2705 (init_psymbol_list): Free any previously allocated psymbol lists.
2706 (): FIXME: Should realloc-down the psymbol lists when done reading
2707 the main symbol file?
2709 * symmisc.c (free_symtab): Free fullname field too.
2711 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
2712 (REGISTER_ADDR): Make result type unsigned int.
2714 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
2715 define REGEX must also define REGEX1 (its dependency).
2717 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2719 * tconfig/i960: No longer works, points you at vxworks960 or
2722 * xgdb.c, XGDB-README: Remove file. Users can get the much
2724 * Makefile.dist: Remove all trace of xgdb.
2726 * breakpoint.c (breakpoint_1): Pass demangle arg to
2727 print_address_symbolic.
2728 (clear_breakpoints): Remove unused function.
2729 (breakpoint_re_set_one): Guts of breakpoint_re_set.
2730 (breakpoint_re_set): Use catch_errors to do them all anyway.
2732 * gdb-int.texinfo (Host versus Target): Add section on what is
2733 a "host" feature versus what is a "target" feature.
2735 * infcmd.c (path_command, path_info): Handle the PATH variable
2736 (object search path) as conveniently as the source search path.
2737 * environ.c (set_in_environ): Set some vars in GDB's environment,
2738 in addition to the child's. PATH, G960BASE, G960BIN for starters.
2739 * source.c (mod_path): New function, from guts of
2740 directory_command, modifies a path. Used by path_command.
2741 (directory_command): Call it.
2742 * defs.h (strsave): Declare.
2744 * utils.c (sevenbit_strings): Add new printing option.
2745 (printchar): Use it.
2746 (strsave): Provide this handy helper routine.
2747 (set_width_command): Rename set_screen_width_command.
2748 (_initialize_utils): "set screen-width" => "set width";
2749 "set screen-height" => "set height"; add sevenbit-strings.
2751 * infcmd.c (do_registers_info): Print floating point registers
2752 in raw hex as well as float format, regardless of whether it is
2753 a "virtual" convertible register.
2754 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
2755 regs as a double, just in case it's being used that way.
2756 * values.c (unpack_long): Comment on array/function coercion.
2757 (unpack_double): Argument is in target byte order now. For
2758 integer arguments, just call unpack_long and float the result.
2759 * m68k-tdep.c: include defs.h for "const" handling.
2760 * remote-nindy.c: Use ieee-float stuff.
2761 (nindy_fetch_registers): Unpack double regs to host double, then
2763 (nindy_store_registers): Pack extendeds to host double, flip
2764 around by misusing unpack_double, send as target double.
2766 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
2767 zero, as when stopped at the first instruction of a process.
2769 * blockframe.c: Fix filename in comment (param.h => tm.h).
2770 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
2771 * tm-68k.h: Fix typos.
2773 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
2775 Changes from a bringup on the DEC Vax under Ultrix 4.0.
2777 * coredep.c (fetch_core_registers): Pass end-address of register
2778 section to register_addr as expected. Don't call supply_register
2779 if we'd just pass it garbage.
2781 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
2783 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
2785 * target.c (push_target, target_info): Cast enums to int for < or
2788 * stack.c (print_frame_info): Identify source file & line
2789 even if we can't print it.
2791 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
2793 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
2795 Clean up IEEE floating point support.
2797 * ieee-float.h: New file.
2798 * ieee-float.c: Write real routines to convert between host
2799 doubles and various target IEEE extendeds.
2800 * m68k-xdep.c: Eliminate assembler code for extended floats.
2801 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
2802 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
2803 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
2804 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
2805 double_to_ieee_extended.
2806 * i960-tdep.c: Define ext_format_i960.
2807 * m68k-tdep.c: Define ext_format_68881.
2808 * sparc-tdep.c: Define ext_format_sparc, though unused.
2809 * Makefile.dist (HFILES): Add ieee-float.h.
2810 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
2813 Obsolete the "coffstrip" program in favor of using BFD's strip.
2815 * nindy-share/coffstrip.c: Remove file.
2816 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
2817 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
2818 * tconfig/nindy960: Remove reference to coffstrip.o.
2820 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
2822 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2824 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
2825 * dbxread.c: Remove static symfile_bfd.
2826 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
2828 * inftarg.c (child_detach): Pop the child_ops vector if the
2829 detach is successful.
2830 * remote-nindy.c (nindy_create_inferior): Don't push a new
2831 nindy_ops since nindy uses the same one for execution and memory
2833 * core.c (core_ops): Use child_attach and child_create_inferior
2834 rather than default attach and create_inferior functions.
2836 Handle floating point registers in core files.
2838 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
2839 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
2840 This version untested since BFD doesn't yet support sun3 core
2842 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
2843 conventions. Fix comments and style. This version has not
2844 been compiled yet, since we have no HP inhouse.
2845 * core.c (get_core_registers): Look for two sections, ".reg"
2846 and ".reg2", and pass both to fetch_core_registers sequentially.
2848 Revise directory path yet again.
2850 * source.c (forget_cached_source_info): Not static any more.
2851 (init_source_path): New default source path is "$cdir:$cwd".
2852 (dir_command): Handle variable arguments ($cdir, $cwd).
2853 (source_info): Print "Compilation directory" rather than
2854 "Originally compiled in" to remind people of $cdir.
2855 (openp): If the path contains $cwd, use current directory.
2856 (open_source_file): If compilation directory is known, replace
2857 first $cdir in path with the compilation directory.
2858 (print_source_lines): Even if we can't print the lines, set the
2859 current symtab and line for future commands like "info source" or
2860 "breakpoint". Also, error message now contains the file name,
2861 line number, and file access error message.
2862 (_initialize_source): Fix help text to describe changes.
2863 * main.c (cd_command): Forget cached source info when we chdir.
2864 * utils.c (strstr): Add simple implementation.
2866 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
2868 * coffread.c (read_one_sym, init_linetable, init_stringtab):
2869 Byte-swap COFF symbol tables if necessary when reading them in.
2870 Use complain() to replace error message in one spot. Needs
2871 corresponding change in bfd/coff-code.h to make some symbol
2872 swapping routines non-static.
2874 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
2876 Merge changes from Eirik Fuller, for UTek.
2878 * defs.h (errno): Add declaration.
2879 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
2880 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
2881 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
2882 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
2883 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
2884 declarations of errno.
2886 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
2888 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
2889 <rpc/rpc.h> and <rpc/types.h>.
2891 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
2893 * i960-tdep.c (examine_prologue): Add new argument limit,
2894 which stops the scan at the end of the prologue, or at the PC.
2895 This fixes a problem where it walks down into the code for the
2896 user's statements if that code looks like function prologues.
2897 Mark Fox and I have been bouncing this code back and forth, making
2898 small changes to it. Callers changed to match.
2900 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
2902 Cleanup for gdb-3.94 release final:
2904 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
2905 the .c files from vx-share and nindy-share, from the various
2906 macros, since they are not found via ALLDEPFILES.
2907 (SFILES): Add tm-i960.h.
2908 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
2909 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
2911 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
2912 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
2914 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
2916 * am29k-tdep.c: Add contribution line.
2917 (examine_prologue): Cache information about function prologues in
2918 the misc-function-vector to avoid lots of references over the
2919 serial line while examining instructions.
2921 * core.c (core_close): New function made from cleanup_core.
2923 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2924 remote-vx.c, remote.c, target.c, target.h,
2925 Update target_ops vector to add attach, close, and load entries.
2926 Use add_syms_addr_command, not add_file_addr_command, for
2927 add_file. Break out close routine from existing code.
2929 * dbxread.c (really_free_pendings): Don't free pending_blocks;
2930 they are in an obstack.
2931 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
2933 (define_symbol): Add symbol type parameter; change callers;
2934 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
2935 it to influence the symbol class on the i960.
2936 (define_symbol): Swap LOC_CONST's into target byte order.
2938 * exec.c (exec_close): New function.
2939 (exec_file_command): Call it.
2941 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
2942 Fix byte order of frame pointer.
2943 (read_var_value): Result of 0 if var's value can't be found,
2944 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
2945 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
2946 (locate_var_value): Use read_var_value and use its lazy address
2947 as the location of the var's value. Lint.
2949 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
2952 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
2953 obsolete Intel versions in favor of vxgdb versions.
2954 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
2955 code dealing with byte order of values, which Intel did in host byte
2956 order rather than gdb-4's target byte order.
2957 (i960_frame_chain_valid): Move to nindy-tdep.c.
2958 (examine_prologue, skip_prologue, frame_find_saved_regs,
2959 frame_args_address, leafproc_return, saved_pc_after_call,
2960 pop_frame): Add vxgdb versions from Mark Fox.
2961 (examine_prologue, frame_struct_result_address): Add code
2962 to deal with the saved value of G13 (struct return address
2964 (frame_args_address): Modify Mark's version to prefer the
2965 saved value over the current value in the topmost frame.
2966 Cache result in the frame info to avoid performance hair in
2968 (print_fault): Add gdb960 code for printing faults.
2969 (_initialize_i960): Actually call check_host.
2971 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
2972 add stub routines. FIXME, these currently just return zero!
2974 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
2975 (attach_command): Call target_attach, not target_open, now.
2977 * infrun.c (normal_stop): Make global, not static, for vx_attach.
2978 (child_attach): Rename from child_open.
2979 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
2980 don't confuse it with a zero step_resume_break_address.
2982 * inftarg.c (child_detach): Eliminate inferior_pid test.
2983 (child_files_info): Clean up message a bit.
2984 (child_ops): Use child_attach, not child_open, to attach.
2986 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
2987 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
2988 findvar.c to here, since it depends on the contents of the
2989 shadow_contents of breakpoints, but keep if #if 0 since it is
2992 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
2995 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
2996 (ptype_command, display_command): Eliminate have_inferior_p and
2997 have_core_file_p in favor of target_has_stack or
2998 target_has_execution.
2999 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3000 code for actually finding the values of arguments, though we still
3001 keep track of the maximum stack offset for use in printing unnamed
3002 arguments. Handle missing FRAME_ARGS_ADDRESS.
3004 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3005 (struct nindy_regs): Define registers passed to/from nindy.
3006 (nindy_fetch_registers, nindy_store-registers): Translate between
3007 nindy and GDB formats for the registers.
3008 (dcache_init): Statically allocate the cache, since it was being
3009 allocated by a malloc that was never freed anyway.
3010 (nindy_create_inferior): Error, not core dump, if no exec file.
3011 (nindy_before_main_loop): Use target_load, not target_add_file.
3013 * remote-vx.c (net_load): Specify large timeout for load
3014 requests. Allow user to break out with INTERRUPT.
3015 (net_break): Remove useless code, clean up. Change callers.
3016 (parse-args, skip_white_space, find_white_space): Clean up arg
3017 parsing to cope with quoted strings.
3018 (net_wait, net_quit): Never call error, just return status.
3019 (vx_read_register, vx_write_register): Cleanup status checking.
3020 #ifdef the code based on which CPU we are using (960 or 68k),
3021 FIXME, this should be completely general but it isn't yet.
3022 (vx_xfer_memory, vx_resume): Cleanup status checking.
3023 (vx_run_files_info): Improve message.
3024 (vx_load_command): Renamed from vx_add_file_command. Allow load
3026 (net_ptrace): Remove unused routine.
3027 (vx_wait): Adopt code from vxgdb960 to cope with broken
3028 connections to target machine and prompt to disconnect. Remove
3029 debug printouts. Map some EVENT_'s to SIGnals.
3030 (add_symbol_stub, vx_open): Print names of object files we found,
3031 and "ok" if we read their symbols OK. Clarify output in general.
3032 (vx_attach, vx_detach, vx_kill): Add these commands.
3033 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3034 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3035 "info files" output, and create_inferior, since we already have
3038 * stack.c (frame_info): Replace Frame_unknown with 0.
3039 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3040 (return_command): Pop until the PC matches as well as the FP,
3041 so it works even if the FP is shared with another function,
3042 as in "frameless" or "leaf" procedures.
3044 * symfile.c (load_command): renamed from add_file_target_command.
3045 (add_syms_addr_command): renamed from add_file_addr_command.
3046 (add_syms_command): Stub to call target_add_syms.
3047 (_initialize_symfile): Change command names and descriptions,
3048 add-file => add-syms, and load from alias to its own command.
3050 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3051 maybe_kill_then_create_inferior): Default for attempts to start
3052 a process, if one is already running, is to ask about killing
3053 it and retry if yes.
3054 (upstack_create_inferior): #if-0 it, strata obsolete it.
3055 (push_target, unpush_target, pop_target): to_close() a target
3056 before unstacking it.
3057 (target_info): Renamed from target_files_info.
3058 (_initialize_targets): Rename "i files" as "i target", accessible
3061 * target.h: Improve comments about the target_ vectored routines.
3063 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3064 Convert commenting style to standard GNU style.
3065 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3066 (SKIP_PROLOGUE): No longer a no-op.
3067 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3068 (*_REGNUM): Sort register numbers.
3069 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3070 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3071 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3072 are now 10 byte extendeds, not 8 byte doubles.
3073 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3074 for nindy versus vxworks targets. FIXME, this should possibly go
3075 in the target vector.
3076 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3077 frame_saved_regs and arg pointer with each frame.
3078 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3079 (FRAME_ARGS_ADDRESS): Use cached result.
3080 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3081 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3082 (PRINT_RAMDON_SIGNAL): Call print_fault.
3083 (POP_FRAME): Now works.
3085 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3086 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3087 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3088 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3091 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3092 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3094 * valarith.c (value_subscripted_rvalue): Avoid handling
3095 floats and doubles specially; it gave alignment errors. Lint.
3097 * valops.c (value_of_variable, value_of_this): Error if unknown
3100 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3101 to avoid alignment problems.
3102 (value_print): Handle unknown value address.
3103 (cplus_val_print): Two args are ignored; remove them. Change caller.
3104 (val_print): Use unpack_long rather than pointer-deref.
3107 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3108 to avoid alignment problems.
3109 (value_being_returned): Error if return value unknown.
3110 (set_return_value): Add bogosity warning, FIXME. *
3112 * TODO: A woman's work is never done.
3114 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3115 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3116 Add ieee-float.o to OBS.
3117 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3118 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3119 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3121 Changes to generalize the VxWorks RPC protocol slightly, to handle
3122 i960 as well as 68000.
3124 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3125 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3126 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3127 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3128 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3129 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3130 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3131 so they will move in target byte order rather than network
3132 byte order (happens to be the same).
3134 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3136 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3138 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3141 Add contribution lines to various files, showing where they
3144 * breakpoint.c (break_insn, check_break_insn_size,
3145 read_memory_nobpt): Remove to mem-break.c.
3147 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3150 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3151 entry has bad register number. This change is not
3152 tested in this release, FIXME.
3154 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3157 * value.h: Force value's contents field to be aligned to hold
3158 at least a double or a long long (if supported). This avoids
3159 doing bcopy's in and out of the contents field.
3161 (step_1): Avoid coredump under obscure circumstances when we
3164 * symtab.h (misc_info): Add field to misc function vector for
3165 any kind of cached information the target code desires. AMD
3166 29000 uses this to avoid repeating examine_function_prologue's.
3168 * coffread.c: Lint. Remove static symfile, read_section_header.
3169 core.c (have_core_file_p): Lint: remove.
3170 expprint.c (print_subexp): Lint.
3171 infptrace.c, valops.c, valprint.c: lint.
3173 Roll in changes from vxgdb-5.0.1:
3175 * symtab.h: Comment byte order of each address class. Add
3176 LOC_LOCAL_ARG for frame-relative args (960).
3177 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3178 symtab.c, symmisc.c: ditto.
3180 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3182 * remote.c (remote_resume): Error if resume with a signal.
3184 * symfile.c (prim_record_misc_function): Clear misc_info.
3185 (fill_in_vptr_fieldno): Check stub type of arg.
3187 * valops.c (value_cast): Avoid looking up names of types whose
3188 name we don't know, to prevent coredump. Sun CC produces typedef
3189 rtx and the name of *rtx is zero...
3191 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3193 Roll in changes from final AMD 29000 port (Tiemann).
3195 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3196 for ../include/a.out.encap.h. This might not work now that BFD
3197 is separately compiled. Instead, BFD support for encap will have
3198 to translate machine type 29k into the right COFF_MAGIC.
3200 * infcmd.c: Remove references to inferior_pid that aren't used
3201 in actual ptrace calls; use target_has_execution, etc.
3202 (have_inferior_p): Remove function.
3203 (program_info): Print target info rather than "process number";
3204 avoid gratuitous messages unless from_tty.
3205 (run_stack_dummy, finish_command): Set proceed_to_finish.
3206 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3207 main.c: Lint. Lose have_inferior_p().
3208 inferior.h (have_inferior_p): Remove, lint.
3209 (proceed_to_finish): Add flag to ask that all regs be saved
3210 by normal_stop, for the few commands that need it, speeding up
3211 serial I/O. Add comments to stop_registers.
3213 * remote-eb.c: Remove newline from breakpoint message we grep
3214 for. Never time out when running the user program.
3218 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3220 Roll in changes from vxgdb-5.0.1:
3222 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3223 symbol in its raw form, we are processing an unlinked ".o" file.
3224 See if the target environment has assigned it an address, using
3225 target_lookup_symbol (VxWorks does), and enter it into the symtab
3228 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3229 68k versions for a simpler version that assumes zero FP at bottom.
3230 Fixes bug of truncated stack reports.
3232 * target.h (target_lookup_symbol): Define this routine's args
3233 and result, finally.
3235 * target.c (nosymbol): Default routine for target_lookup_symbol.
3236 (target_default): Default lookup_symbol and call_function too.
3237 (files_info): Only print has_all_memory warning if a non-dummy
3240 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3241 vx_convert_from_virtual): If target does not have floating point,
3242 zero register "values", and avoid doing cross-net conversions.
3243 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3244 (vx_open): Rearrange code that attaches to target and reads
3245 symbols for all loaded modules, to work if some of the modules
3246 are not accessible. Add symbol_stub() and add_symbol_stub()
3247 as callbacks from catch_errors(). Allow connect attempt to be
3248 interrupted painlessly with ^C (FIXME, there are still some bugs
3249 if the interrupt happens during symbol reading.). Print
3250 final message with puts_filtered, since symbol messages are
3255 * main.c (catch_errors): Only print errstring if non-null.
3256 (command_loop): Avoid an ioctl per command to test ISATTY.
3258 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3259 (vx_xfer_memory): Return correct result!
3260 (vx_files_info): Indicate whether target has float or not.
3261 (vx_lookup_symbol): Complain, not error, if target gone.
3262 (vx_open): Print "Connected" msg before disabling immediate-quit.
3263 [FIXME: lookup_symbol and vx_open changes need testing.]
3265 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3266 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3267 contributor lines and update copyrights to 1991.
3269 Changes from an attempted H-PUX host port:
3271 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3272 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3273 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3274 * remote-vx.c: include <sys/time.h> for HPUX.
3275 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3276 "core_file_command" routine to BFD regime. May not work yet.
3278 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3280 * xgdb.c: Replace X10 version with some VJ version.
3281 (FIXME: Its copyright assignment is not on record.)
3282 * xgdb.c: Update include files to X11R4 (Xaw crud).
3283 (xgdb_display_source, create_text_widget): fix call to
3284 get_filename_and_charpos. Rewack source window stuff for X11R4
3285 (gleaned from include files, and "nm's" of binary libraries, since
3286 I had no doc available).
3287 (append_selection, append_selection_word): Disable with FIXME
3288 since R4 changed interface here.
3289 (create_buttons): Add back the old set of buttons.
3290 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3292 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3293 Roll VERSION to 3.94 (not yet final though).
3295 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3297 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3298 obstack_int_grow, obstack_int_grow_fast): Eliminate
3299 cast on left of assignment, which gives MIPS cc fits and is
3302 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3303 F_ALIAS. Use printf, not fprintf, when not passing a file
3305 (compare_opcodes): Check that identical instructions have
3306 identical opcodes, complain otherwise.
3308 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3309 was reported by Roland McGrath.
3310 (unimp): Only match if exactly zero instruction. (Roland)
3311 (branches and traps): Generate all variations of these
3312 instructions with macros, based on a single call that defines
3313 each condition name and its binary representation.
3314 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3316 * valprint.c (val_print_fields): Take, and use, format parameter.
3317 This means that "p/x struct" again prints the elements in the
3318 desired format. Changed callers.
3320 * stack.c (frame_info): Use filtered output, and indicate wrap
3321 points. Remove kludgy formatting designed to avoid line wrap.
3323 * utils.c (wrap_here): If the line is already full (because
3324 we had printed a long indent or long wrapped string), do an
3325 immediate newline-and-indent.
3327 * m68k-pinsn.c (print_insn_arg): Bugfix from
3328 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3329 instruction is incorrectly disassembled as bkpt #8.
3331 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3332 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3333 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3334 and then will dump core (sometimes). I traced it back to an
3335 uninitialized symfile_name in psymtab_to_symtab.
3336 (const_vol_complaint): Add quotes to message.
3337 (define_symbol): Only believe line number if gcc_compiled.
3338 Avoid allocating symbol if we will not return it.
3340 Add target strata support so that newly established targets go
3341 into their right place in the target stack (e.g. a new exec file
3342 doesn't wipe out the ability to access the running process).
3344 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3345 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3346 and initialize it properly in all the targets.
3348 * target.h: Document strata. Change return type of push_target.
3350 * target.c (nomemory): new function for dummy memory access.
3351 (tcomplain): Rename complain, now also used in symfile.c.
3352 (push_target): Push targets within strata. New return value shows
3353 whether new target is on top of stack or not. Always keep dummy
3355 (target_files_info): Ignore dummy target.
3357 * core.c (core_open): Warn user, and skip accessing file, if the
3358 core target is not the topmost target in the stack.
3359 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3362 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3363 target_ops, it doesn't belong there since we have no regs there.
3364 Change name of target from machine => memory to clarify.
3366 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3368 * Freeze version 3.93 for release.
3370 * Makefile.dist: Handle vx-share and nindy-share subdirs
3371 properly when building gdb.tar.Z.
3373 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3374 printed in various places, so I could change just one copy.
3376 * dbxread.c, coffread.c: Change references to bfd->iostream
3377 to cast to FILE *, now that BFD avoids needing types defined
3378 in other header files.
3380 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3382 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3383 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3384 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3385 (actually gcc -Wall).
3387 * dbxread.c: Remove first_global_sym, last_global_sym, since
3388 they are never referenced.
3390 * defs.h (baud_rate): Declare.
3391 main.c: Define it, and add the -b option to set it.
3393 * gdb-int.texinfo: Add text on how to define a new host or target
3394 architecture, prompted by Per Bothner's questions about MIPS
3397 * gdb.texinfo: Document "complaints". Change doc of -q since
3398 gdb no longer prints the copyright and blurb if you specify a file
3399 name to be debugged (just like Emacs). Add doc for Nindy-specific
3400 command line flags for specifying target serial port and such.
3401 Update copyright to 1991.
3403 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3404 has taken over for us the job of ripping up executable files. The
3405 crud caused Per Bothner's port to not compile.
3407 * infrun.c (normal_stop): Avoid printing "Program exited
3408 normally" if we are in batch mode. This allows a GDB which
3409 executes a program on a target system, to behave like a Unix
3410 command (input from stdin, output to stdout, no extraneous
3413 * main.c (main): Allow additional machine-dependent command line
3414 options to be specified with the ADDITIONAL_OPTIONS,
3415 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3416 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3417 processing to occur just before the main loop with
3418 BEFORE_MAIN_LOOP_HOOK.
3419 (main): If a "core file" argument is specified, and it is not a
3420 core file, try it as a process ID to attach.
3421 (symbol_completion_function): Attempt to cope with
3422 "show screen-" TAB, not very successfully. This needs more work,
3424 (batch_file): New function, returns whether we are reading
3425 commands from an interactive tty on stdin, or from somewhere else.
3426 Called by normal_stop since it doesn't get from_tty passed down
3427 to it like many commands do.
3429 * remote-nindy.c: Handle command line options for nindy
3431 (nindy_before_main_loop): Prompt user for tty name if they
3432 don't specify it before getting to the interactive command loop.
3434 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3435 and -r command line options. Also add hook before main loop
3436 to make it easy to specify a tty.
3438 * TODO: More things to do, one done.
3440 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3442 * dbxread.c: Make complaint() calls pass pointer, not struct.
3443 Add complaints about badly formatted C++ type information
3444 (const/volatile indicator, and parse errors resulting in
3445 error_type). Fix C++ virtual member fn comment.
3446 (read_struct_type): Avoid bumping pointer if we got a parse
3447 error; this prevents our walking beyond the end of a string.
3448 Terminate loop on null char as well as semicolon.
3449 (process_one_symbol): Fix the LBRAC fix so that it uses the
3450 last previous SLINE, FUN, or SO record's PC address. C++ debug
3451 symbols did not have SLINE records in a useful order compared
3452 to the LBRAC records.
3453 (define_symbol): Handle "catch" records.
3455 * symtab.c (check_stub_type): Added new complain
3456 `stub_noname_complain' and added a consistency check to
3457 keep the debugger from crashing when finishing from an
3458 exception frame. A real fix will be needed later.
3460 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3462 * infcmd.c (attach_command): Make global.
3464 * Makefile.dist (REMOTE_OBS): Make these compile by default,
3465 but make them easy to comment out. Perhaps later they should
3466 be enabled by what CPU you configure for? FIXME.
3467 (VERSION): Roll to 3.93.
3468 (pinsn.o): Remove rule for obsolete file.
3469 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
3471 Run down a problem that manifested by printing the wrong function
3472 name in stack traces of read_ofile_symtab. Turned out that the
3473 problem was the SunOS 4.1.1 (and previous) C compiler outputs
3474 the LBRAC symbol with an address in the *data* segment, which
3475 blew our binary search through the blocks.
3477 * dbxread.c: Use the complain() facility consistently to bitch
3478 about problems in the symbol file we are reading.
3479 (finish_block): Add code to check the nesting of the blocks;
3480 complain and Procrust them to fit if wrong.
3481 (make_blockvector): Check the order of the blocks, complain
3482 [but don't cope] if wrong.
3483 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
3484 symbols to be sure their PC value is greater than the last SLINE
3485 (line number) symbol we've seen, complaining and adopting the
3486 SLINE PC value if wrong.
3488 * symfile.h (struct complaint, complaint_root, complain,
3489 clear_complaints): Add.
3490 * symfile.c (complain, complaint_root, clear_complaints): Add
3491 facility to deal with non-fatal complaints and to regularize their
3493 (symbol_file_add): Clear complaint counters to allow new complaints.
3494 (initialize_symfile): Add 'set complaints' and 'show complaints'.
3496 * dbxread.c (dbx_symfile_read): Remember the address and size
3497 of the string table for the main symbol file, so we won't read it
3499 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
3500 to avoid reading the string table yet again. Lint.
3501 (throughout): Improve filtered output, including word wrap.
3502 (read_range_type): Improve Bothner's fix to handle other types too.
3504 * utils.c: Improve line wrap implementation. Handle unlimited
3505 width by making chars_per_line unsigned.
3506 (puts_filtered): New, easy, function.
3508 * defs.h (puts_filtered): add.
3510 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
3511 call the identical sort_symtab_syms() in symfile.c instead.
3513 * expread.y: Suggest the `file' command rather than `symbol-file'.
3515 * command.h (enum var_types): Add zinteger for seroable
3517 * command.c (do_setshow_command): Handle var_zinteger. Restructure
3518 nested if's into a switch.
3520 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
3521 we did not stop because of a breakpoint (it must have been for
3522 some other reason, like a "stepi"), so don't print anything.
3524 * symtab.c: Include <sys/types.h> all the time. Now that BFD
3525 doesn't include <sys/types.h>, old SunOS's require it for
3528 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
3530 A test port of gdb-3.92.6 to the Sony NEWS.
3533 Don't normally link in remote- or vx stuff.
3534 Some of it doesn't compile, and it wastes space for 99% of the users.
3535 Remove reference to no-longer-used HAVE_VPRINTF.
3536 Fixed BFD_DEP typo to BFD_DIR.
3538 Fix cast in arg to bfd_h_getlong.
3539 Make char *prefix be const.
3540 Fix how certain range types are mapped into builtin unsigned int types.
3542 Remove 2 #includes. They cause errors (on Sony, at least),
3543 and aren't needed (they wern't in earlier versions).
3545 print_address_symbolic should never demangle labels
3546 (since it prints *assembler-level* labels).
3548 [This was superseded by the change to printcmd below.]
3551 Add some "volatile" return types to avoid warnings.
3552 If MISSING_VPRINTF add vprintf function and not just macro
3553 (since vprintf is used in printcmd.c).
3555 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
3556 (The latter isn't grokked by some PCC-based compilers.)
3558 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
3560 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
3561 * nindy-share/coffstrip.c
3562 Added some forward declarations (otherwise, gcc complains
3563 about implicit extern redefined as static).
3565 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3567 Changes inspired by Per Bothner:
3568 * printcmd.c (print_address_symbolic): Take additional parameter
3569 specifying whether to demangle.
3570 (print_address): Pass in asm_demangle to control demangling.
3571 (print_address_demangle): New fn, takes explicit arg to control
3573 * utils.c: Add new vars demangle and asm_demangle, and let them
3575 (fputs_demangled): If !demangle, just print the argument.
3576 (fprint_symbol): If !demangle, just print raw symbol.
3577 * valprint.c (val_print): Call print_address_demangle rather than
3578 print_address, to cause demangling to depend on the global
3579 rather than assembler-level demangling setting.
3580 * WHATS.NEW, gdb.texinfo: Document.
3582 * main.c (show_command): Show all settings if no arg.
3583 (initialize_main): Make "info set" the same as naked "show".
3584 * command.c (cmd_show_list): Handle prefix commands in the
3585 list, and print the name of the setting as well as its English
3586 description and value.
3588 Allow gdb functions to specify where a line should wrap if it
3589 exceeds the size of a terminal line. Use it to make the output
3591 * utils.c (set_screen_width_command): New fn, mallocs a buffer
3592 of the right size when screen width changes.
3593 (set_screensize_command, screensize_info): Remove #if 0'd fns.
3594 (wrap_here): New fn, indicates a point in the output where we
3595 should wrap the line rather than just letting it overflow at a
3597 (fputs_filtered): Implement wrapping.
3598 (n_spaces): New fn, returns a pointer to N spaces.
3599 (print_spaces_filtered): Use n_spaces.
3600 * defs.h (n_spaces): Declare.
3601 * stack.c (print_frame_info): Wrap with 4-space indent after
3602 fn name and before filename and line number.
3603 * printcmd.c (print_frame_args): Wrap with 4-space indent
3604 before each argument name is printed.
3605 * valprint.c (value_print): Wrap with no indentation before
3607 (val_print_fields): Wrap with indentation relative to nesting
3608 level before each field name.
3609 (val_print): Wrap with nesting indentation before array elements.
3610 * command.c (do_setshow_command): Avoid extra newlines,
3611 wrap with 4-space indent around values printed, end with period.
3612 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
3614 * breakpoint.c (breakpoint_1): Implement addressprint for
3615 "info breakpoints" display. Change file name and line number
3616 format to " at file:nnn" rather than " (file line nnn)".
3617 * gdb.texinfo: Document.
3620 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3622 Frozen for gdb-3.92.6 release.
3624 README, WHATS.NEW: Update for 3.92.6 release.
3626 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
3627 coffread.o from configs since it is now built by default.
3628 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
3629 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
3630 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
3631 from configs since it is now built by default.
3633 Makefile.dist: Update for release 3.92.6. Handle files that
3634 have been moved to ../include, ../getopt, or ../bfd. Add
3635 saber.suppress and tests directory. Add config.status to
3636 the release (it will say "none").
3638 coredep.c: Minor formatting fixes.
3640 These changes were made in early December but only checked in now:
3641 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
3642 nindy-share/nindy.c: lint
3643 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
3644 register values coming back from the target; we store values
3645 in target byte order everywhere.
3647 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
3649 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
3651 * valprint.c (cplus_val_print, val_print_fields): New functions,
3652 which print C++ objects. They conspire to avoid printing a
3653 virtual base class more than once, following all the twists and
3654 turns of C++ virtual base rules.
3655 (val_print): Call the above rather than do it by hand.
3657 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
3658 symbol file, not for added files like shared libs. This really
3659 needs to be generalized to a timestamp per file.
3661 * core.c (cleanup_core): Avoid coredump if no core file.
3663 * config.gdb: Accept -host or -target in place of +host or
3666 * coffread.c (find_linenos): Avoid desupported BFD interface
3667 to line numbers. We still read them manually rather than using
3668 BFD's "generic" features.
3670 * gdbrc.tex, threecol.tex: Add GDB reference card and its
3672 Makefile.dist: Add refcard to OTHERS list for creating tar files.
3674 * Makefile.dist: Eliminate use of $< in explicit targets.
3676 * readline/Makefile: Use $< rather than $*.c, which does not
3677 include the VPATH in GNU Make.
3679 * tconfig/i960-bout, tconfig/i960-coff: These are identical
3680 copies of tconfig/i960, added for global configuration
3681 compatability. All i960 versions can read both coff and b.out.
3683 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
3684 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
3687 * TODO: Think of more things to do.
3689 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
3691 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
3692 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
3693 64-bit float conversion.
3695 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
3696 equivalent to sun?os4 so global config works.
3698 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
3700 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
3702 * main.c: Only declare linesize once; declare pagesize not at
3703 all, since it is never used.
3704 (main): Clear newly allocated line before it is used.
3706 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
3708 Further stabilization for the Intel 960.
3710 * Makefile.dist: Parameterize the location of the "include"
3711 and "bfd" directories, as well as "getopt". Add symfile.c.
3712 Link in both dbxread and coffread. Fix up "make depend" to
3713 rewack the locations of include, bfd, and getopt in its output.
3715 * README: Document moving include files, improve some of
3718 * coffread.c: Move common code out to symfile.c. Change
3719 symbol_file_command style interface to use new *_symfile_init
3720 and *_symfile_read interface under BFD. Use BFD internal
3721 info to locate line table, symbols, etc.
3723 * core.c (core_fetch_registers): Rename to get_core_registers
3724 to avoid confusion with fetch_core_registers.
3725 (register_addr): Move to coredep.c, which is already machine
3726 dependent. This leaves core.c pretty clean of dependencies.
3728 * coredep.c (register_addr): Accept this routine from core.c.
3730 * dbxread.c: Move common code (with coffread.c, etc) into new
3731 symfile.c. Each psymtab now contains a pointer to the
3732 format-dependent function that knows how to read it in. Make
3734 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
3735 (process_one_symbol): Add code to complain about a "compiler bug
3736 we muzzle here", if we actually see it.
3738 * eval.c (evaluate_subexp): Insert missing "break" statements
3739 in code that determines whether a variable is an lvalue in
3740 memory, register, or whatever. I detected this via a compiler
3741 bug in which it *almost* mashed out the whole switch statement.
3743 * gdb-int.texinfo: Add minor sections on configuring gdb for
3744 release, and about the README file.
3746 * infcmd.c (registers_info): Fix formatting somewhat. Still
3747 not as pretty as before, but it handles byte swapping.
3749 * remote-nindy.c: If data cache routines are interrupted while
3750 waiting for the remote end, be sure that any uninitialized cache
3751 blocks are on the free list, not on the valid list!
3753 * symfile.h: Flesh out this header file with all the various
3754 routines and variables that have been merged in from dbxread.c
3755 coffread.c, and symtab.c to symfile.c.
3757 * symfile.c: New file, containing code common to dbxread.c,
3758 coffread.c, and some code from symtab.c. All generic code for
3759 reading symbol files should be in here now.
3760 (unrecord_misc_function): Remove unused function.
3762 * symtab.h: Remove file-reading things to symfile.h.
3764 * symtab.c: Remove file-reading things to symfile.c.
3766 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
3767 to decode i960 fault types.
3769 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
3770 target.c: Change type of the "resume" function from int to void,
3771 since its result was never used.
3773 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
3775 * main.c: Replace "stupid" with "caution"; you now "set caution
3778 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
3780 * infcmd.c (do_registers_info): Call val_print to deal with the
3781 byte order of the registers being printed. FIXME, this makes
3782 the formatting of the output uglier.
3784 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
3785 defined, call it for signals the debugger doesn't itself use.
3786 The i960 uses this for more detailed fault information.
3788 * remote.c (remote_open): If arg is null, print help rather than
3791 * sparc-xdep.c (register_valid): Avoid declaring size, since
3792 various modules will think of various sizes depending on the
3793 architecture of their tm-file. FIXME, we need protection against
3794 actually entering one of those modules, which would clobber
3795 storage if not for the target architecture compiled into gdb.
3797 * stack.c (up_command, down_command): Always print the frame
3799 (up_silently_command, down_silently_command): New commands
3802 * i960-pinsn.c (reg), i960-tdep.c: Lint.
3804 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
3805 more parameters than it used to.
3807 * findvar.c (registers): Increase slop to 256 bytes, which should
3808 protect us against even most RISC machines with large register
3810 (locate_var_value): Move declaration inside related ifdef.
3812 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
3813 throughout, to avoid throwing away buffered input from the board.
3814 (nindy_wait): Supply_register takes addr_of_value, not value.
3815 (i960_print_fault): Renamed from i80960_fault.
3816 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
3817 (nindy_store_registers): Avoid regs_changed stuff, just stuff
3819 (nindy_create_inferior): Don't bother to write PC_REGNUM since
3820 we can set the PC in the call to proceed(). Unpush nindy_ops
3821 before pushing it on top, to avoid message to user. Eliminate
3822 commentary from Unix machines that just misleads here.
3823 (reset_command): Fix error message to suggest target command.
3825 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
3827 Release 3.92.5 as frozen.
3829 Stabilize the merged release...with help from lint, Saber C,
3832 Everywhere: Add include files needed to declare return types
3833 of functions called.
3835 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
3837 * breakpoint.h: Add undeclared breakpoint functions, and some
3838 functions for display handling since I couldn't think of a better
3841 * breakpoint.c (insert_breakpoints): Make code for disabling
3842 shared library bkpts more likely to work. It's used when we
3843 rerun a program and stop before the shared library has been
3845 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
3846 cast from pointer, so it squeezes through catch_errors.
3847 (bpstat_stop_status): Fix logic broken some time ago. We now
3848 always create a bpstat if the stop address matches a breakpoint,
3849 even if we don't stop there -- just like the old code used to do
3850 before I got my fingers into it (sigh).
3851 (breakpoint_1): Print "ignore count" after "stop only if"
3852 condition, since that's how it actually works.
3853 (mention): Handle watchpoints as well as breakpoints.
3854 (watch_command): use set_raw_breakpoint and mention to do most
3855 of the work (and initialize all the fields!). Only pass one
3856 arg to parse_c_expression, since that's all it takes.
3858 * command.c (not_just_help_class_command): Rename arg to args
3859 since we ignore "unused argument" warnings on vars named "args".
3860 inflow.c (child_terminal_info): ditto.
3861 infptrace.c (kill_inferior): ditto
3862 main.c (catch_errors, version_info, quit_command, pwd_command,
3863 source_command, dump_me_command, editing_info,
3864 set_history_size_command, set_history, show_history,
3866 stack.c (locals_info): ditto
3867 target.c (target_files_info): ditto
3868 valprint.c (set_input_radix, set_output_radix): ditto
3870 * core.c: Remove old variables for handling core and exec file
3871 sections (data_start, data_end, stack_start, stack_end,
3872 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
3873 text_end, exec_data_start, exec_data_end, text_offset,
3874 exec_data_offset, data_offset, stack_offset). They're
3875 superseded the more general build_section_table and
3877 (get_exec_file): Mention the `file' command.
3878 (read_memory_check): Rename to memory_error, and only call it
3879 in the case of an actual error.
3880 (read_memory, write_memory): call memory_error.
3881 (core_fetch_registers): Register section name is ".reg".
3883 coredep.c: Remove a bunch of crud now that all this file does
3884 is pull the registers out of a core file.
3885 (fetch_core_registers): Rewrite to actually work, I hope.
3887 dbxread.c: Use a.out.gnu.h, not system a.out, now.
3888 Replace index() with strchr(). Remove all the pre-BFD macro
3889 definitions for accessing the symbol file.
3890 (struct dbx_symfile_info): Encapsulate the information that
3891 dbx_symfile_init needs to pass to dbx_symfile_read in this
3894 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
3895 dbx_symfile_discard): Rearrange symbol file reading to divide
3896 the format-specific part from the format-independent part,
3897 leaving the format-independent part such as file name expansion
3898 and opening in symtab.c. This replaces
3899 partial_symbol_file_open and partial_symbol_file_read.
3900 Symbol_file_read, add_file, add_file_target_command,
3901 add_file_addr_command move to symtab.c. Pass an explicit
3902 "mainline" flag for when reading the main symbol table, rather
3903 than relying on the offset address to be zero or nonzero.
3905 (dbx_symfile_read): Don't allow void *'s to be printed as
3907 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
3908 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
3909 macro" debug version really work.
3910 (read_dbx_symtab): Remove unref'd parameter inclink.
3911 Avoid swapping N_SLINE symbols, for speed.
3912 Merge N_TEXT!N_EXT case with the other external symbol
3913 definitions' case. Add comments.
3914 (start_psymtab): Allocate the symfile name in the psymtab on
3915 the psymbol_obstack, rather than using the caller's storage.
3916 (end_psymtab): Only allocate a dependencies list if there are
3918 (psymtab_to_symtab_2): Use BFD when reopening file to read
3919 its symbols for real.

3922 (read_huge_number): Add FIXME about overflows.
3923 (read_range_type): Add FIXME about comparing a long to 1<<32.
3925 * coffread.c: Minor changes to move things closer to the new
3926 regime with symtab.c and dbxread.c Major work is still needed
3929 * exec.c (exec_file_command): Remove old variables (see core.c
3931 (xfer_memory): If memory transfer is right at the end of a
3932 section, don't lose.
3934 * findvar.c (get_saved_register): If value is in a real
3935 register, LVAL is lval_register, not lval_memory.
3937 frame.h: Declare print_sel_frame and record_selected_frame.
3939 gdb-int.texinfo: New file, for GDB internals documentation.
3940 Very simple, unformatted doc of cleanups is there for now.

3943 section addresses and offsets. (See core.c above.)
3944 Declare fetch_core_registers and registers_fetched.
3946 getopt.c: Declare char *alloca(); even on SPARC.
3948 infcmd.c (run_command): Call target_kill rather than
3950 (step_command, next_command, stepi_command, nexti_command):
3951 Declare from_tty parameter even though we don't use it.
3952 (run_stack_dummy): argument BUFFER is a char array, not
3953 a pointer to REGISTER_TYPE.
3954 (finish_command): using_struct_return needed a value *,
3955 not a struct symbol *.
3957 * infptrace.c (child_xfer_memory): To avoid dependency on
3958 where sections are in memory, try PT_WRITE_D and if that fails,
3959 try PT_WRITE_I. Most Unixes don't care which you use.
3961 * infrun.c (step_resume_break_shadow): Change to array to
3962 match other breakpoint shadow storage.
3963 (clear_proceed_status): Pass address of bpstat to
3964 bpstat_clear, not the bpstat itself.
3965 (child_create_inferior): FIXME comment about if the child
3967 (start_inferior): Remove old function.
3968 (child_open): Use target_kill rather than kill_inferior.
3969 (wait_for_inferior): Ditto.
3970 (insert_step_breakpoint, remote_step_breakpoint): Use
3971 new step_resume_break_shadow.
3973 * inftarg.c (child_wait): If all child processes die,

3976 * main.c (command_line_input): When scanning for comments,
3977 don't coredump on unclosed quotes.
3978 (quit_command): Use target_kill rther than kill_inferior.

3982 * printcmd.c (print_command_1): Initialize "fmt" if no format
3983 is specified by the user.
3984 (print_frame_args): Only add to args_printed if we are
3985 actually fetching args from the stack (avoiding undefined
3987 (_initialize_printcmd): Remove bogus \{ from string.
3989 * remote-eb.c (eb_open): Avoid coredump on no argument.
3991 * remote-nindy.c: Bring out of Intel environment into new
3992 target environment. Remove all conditional compilation on
3993 I80960. Massive hacking throughout.
3994 (nindy_xfer_inferior_memory): New routine stolen from
3996 (nindy_create_inferior): New routine pieced together, probably
3997 not quite working yet.
3998 (nindy_ops): New target_ops struct for nindy.
4000 * remote-vx.c: Use write_memory rather than target_write_memory
4001 to get error checking.
4002 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4004 (vx_create_inferior): Use target_terminal_ours...
4006 * signame.c (_initialize_signame): Always initialize, since
4007 we need the table for things other than psignal.
4009 * solib.c (solib_add): Use symbol_file_add, not add_file.
4010 (solib_address): Return boolean result rather than struct
4011 pointer which nobody else knows the type of.
4013 * sparc-tdep.c, valops.c: Use write_memory rather than
4014 target_write_memory, to get error checking.
4016 * stack.c (locals_info, catch_info, args_info,
4017 get_selected_block, frame_command, up_command): Use
4018 target_has_stack, rather than have_inferior_p or
4021 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4023 * symfile.h: New file, defining the interface between the
4024 generic and object-file-specific symbol reading code.
4026 * symtab.c: Move generic symbol-reading interface to symtab.c,
4027 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4028 table to map BFD targets to symbol-reading modules in GDB.
4029 Change index to strchr.
4030 (lookup_struct_elt_type): Use error() rather than hand-made
4031 simulations thereof.
4032 (lookup_partial_symbol): Speedup slightly when length == 0.
4033 (symbol_file_add): New function.
4034 (symbol_file_command): Call it.
4035 (symfile_open, symfile_init): New function.
4036 (add_file_target_command, add_file_addr_command): moved from

4041 * target.h (target_files_info): Don't declare, never called
4044 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4045 files to determine stack end address.
4047 * valarith.c (value_x_binop, value_x_unop): Change error message
4048 to be more useful. Pass proper argument to value_struct_elt.
4050 * valops.c (value_assign): FIXME comment that long long
4051 bitfields will break here.
4053 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4054 Update `make saber_gdb' to work better.
4056 * TODO: A woman's work is never done.
4058 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4059 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4060 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4061 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4062 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4063 valops.c, valprint.c, exec.c: Lint.
4066 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4068 Continuing Intel 960 port merge of GDB.
4070 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4071 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4072 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4073 Wack over "make depend" so it handles files in subdirectories
4074 vx-share, nindy-share, bfd, and in the current directory.
4076 * blockframe.c (get_prev_frame_info): Remove fatal error
4077 if stack not defined.
4079 * core.c (core_open, core_detach): New functions that handle
4080 the old "core-file" command as "target core" and "detach" instead.
4081 (core_file_command): Call them.
4082 (core_xfer_memory): Use common routine xfer_memory.
4084 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4085 dbxread now uses bfd for everything but symbol reading itself.
4086 BFD internals are used to drag out the relevant file offsets.
4087 (partial_symbol_file_open): Change args all around for BFD.
4089 * symtab.c: Rename "value" to "val" everywhere, so we can
4091 (symbol_file_command): New command, moved from dbxread.c
4092 and coffread.c. It uses BFD to read the file, then vectors
4093 based on its type, to dbx or coff symbol readers.
4094 * symtab.h: Extern a few vars for symbol_file_command.
4096 * target.h: Breakpoint takes a char * save area, not a char **.
4098 * valprint.c (val_print): When unpacking bitfields, offset
4099 the address in gdb of the value, if it is declared with a shorter
4100 type. Remove the last "runtime kludge test" of host byte order.
4102 * utils.c: Remove old my_bfd_read routine.
4104 * stack.c (frame_info): Use target_has_stack. Print program counter
4105 register's actual name rather than "pc", since it's called the
4106 "ip" (instruction pointer) on the i960 (sigh).
4108 * target.c (target_command): Add command for selecting a target
4109 type and calling its open routine. This is used for initiating
4110 communication with a particular target, in a generic way.
4112 * tm-i960.h: Update for modern gdb. Remove semicolons from
4113 various macros. Handle reading struct return convention, and
4114 error-out attempts to return structs with the "return" command.
4115 Be sure gdb doesn't think we know how to call functions in the
4118 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4119 to i960_xxx in lower case.
4120 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4121 not being defined yet.
4123 * remote.c (remote_open): Call start_remote to initialize
4124 wait_for_inferior during open.
4125 (remote_xfer_inferior_memory): Return length written rather
4128 * remote-vx.c (target_command -> vx_open): Use new generic
4130 * remote-eb.c, inftarg.c, exec.c: ditto.
4132 * infrun.c: Fix comments.
4133 (attach_program -> child_open): Use new generic target command.
4134 (wait_for_inferior): Clear saved register values before target_wait,
4135 so target_wait can set some of them if convenient.
4137 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4138 Return success indicator, not void.
4139 (child_xfer_memory): Avoid fetching initial word if we'll
4140 overwrite it anyway.
4142 * infcmd.c (attach_command): Use new generic target open routine.
4143 (_initialize_infcmd): Update doc on attach and detach commands.
4144 (do_registers_info): Merge in a byte-order problem as a FIXME
4147 * findvar.c (find_saved_register): Avoid problem in current frame.
4148 (read_relative_register): Ditto.
4149 (write_register): Convert byte order on the way out.
4151 * exec.c (file_command): Add.
4152 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4153 (xfer_memory): Common function between core_xfer_memory and
4155 (exec_xfer_memory): Use it.
4157 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4159 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4160 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4161 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4163 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4165 Merge Intel 960 port of gdb, continuing...
4167 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4168 symbol_file_command): Pass from_tty arg to hush 'em up.
4170 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4171 Add magic numbers for 960 COFF format.
4173 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4175 Merge Intel 960 port of gdb, from Intel "1.2" release.
4177 CHANGE_LOG entries from their port, which was based on
4180 Thu Sep 6 11:02:22 PDT 1990
4181 Remove temp file if download is interrupted.
4183 Wed Aug 1 09:08:33 PDT 1990
4184 Now uses binary protocol to talk to NINDY.
4185 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
4186 Times out after 5 seconds when trying to talk to NINDY.
4188 Tue May 29 12:54:49 PDT 1990
4189 Added variable baud rate (-b switch).
4190 Source code reorganization.
4192 Thu Apr 26 11:09:55 PDT 1990
4193 More cleanup of batch mode; specifically, execute "-s", "-e", and
4194 "-se" switches as soon as they are encountered on the invocation line.
4196 Fri Apr 20 13:47:15 PDT 1990
4199 Thu Apr 19 09:54:28 PDT 1990
4200 Add 'reset' command.
4202 Wed Apr 18 09:48:07 PDT 1990
4203 After opening remote tty, wait for 1 second to go by without input
4204 from it before trying to talk to NINDY (fixes problems with the
4205 Heurikon HK80/V960E).
4207 Mon Apr 4 16:33:05 PDT 1990
4208 Some output was not being suppressed in 'batch' mode.
4210 Thu Mar 22 15:31:11 PST 1990
4211 Ask user if old symbol table should be deleted when new file is
4214 Allow user to run a program downloaded before gdb960 was brought up.
4216 Correct "exec-file" help message for i80960 context.
4218 Correct bug in calculating user space address: could occasionally
4219 corrupt user program.
4221 Make sure to zero low-order bits in rip's because of bug in 960CA
4222 A-step part: could cause operation faults when "next"ing across
4225 Correct bug that made it impossible to get source line numbers for
4226 code loaded at addresses higher than 0x7fffffff.
4228 Wed Jan 10 12:43:22 PST 1990
4229 Open remote tty for exclusive use.
4231 Fri Jan 5 12:14:42 PST 1990
4232 Correct disassembly (CA manual was right after all):
4233 opcode for sysctl is 0x659
4235 Mon Oct 23 12:03:04 PDT 1989
4236 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4238 Mon Oct 16 14:15:09 PDT 1989
4239 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4241 Mon Oct 2 15:56:31 PDT 1989
4243 Added 960CA disassembly support.
4245 To simplify maintenance:
4246 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4248 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4249 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4250 - made disassembly interface identical to that in gdmp960.
4254 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4256 * target.h: Allow targets to stack. Add target_has_memory,
4257 _registers, etc. Restructure memory access and "info files"
4258 to walk the target stack.
4259 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4260 target.c: Change tables to match target.h.
4261 * inflow.c (child_mourn_inferior): pop child_ops.
4262 (generic_mourn_inferior): Use new has_stack flag.

4264 * inftarg.c (child_files_info): New "info files" regime.
4265 * remote-eb.c: New memory regime, new info files.
4266 * remote-vx.c: New memory regime, new info files. Now use
4267 separate targets for VxWorks attachment to machine, and
4268 actually running a process under VxWorks, since one has
4269 stack & execution & regs and the other doesn't.
4270 * remote.c: New memory regime, new info files.
4271 * sparc-xdep.c (fetch_core-registers): New memory regime.
4272 * target.c: New routines and support for stacked targets,
4273 new memory regime, new info files regime.
4276 Generalize section handling for an arbitrary number of sections,
4277 including use of the new BFD (binary file) library.
4278 * gdbcore.h: Add struct section_table.
4279 * exec.c (build_section_table): Iterate all sections and
4280 record what gdb needs to know about them.

4287 * dbxread.c: Quick changes to make it compile with new BFD.
4288 * utils.c (error): Avoid using bfd_error in generic routines.
4290 * core.c (core_fetch_registers): Get from the ".regs" section of
4292 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4294 * inferior.h (attach_flag): Export.
4295 * infcmd.c (run_command): use new target_create_inferior.
4296 * infrun.c (child_create_inferior): Don't return result.

4302 since been deleted, such as temporary breakpoints.
4303 infcmd.c (program_info): ditto.
4305 * core.c (core_file_command): Display the frame where the core
4310 * remote-vx.c (target_command): Merge in target command from
4311 targ-vx.c. A few other cleanups.
4313 * TODO, Projects: Lots more stuff to do...
4315 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4317 Massive changes to wall off the remote-debugging interface
4318 behind a function vector. The port to handle VxWorks targets
4319 is also part of this.
4321 All files: Replace references to renamed functions,
4322 remove references to remote_debugging, remove references to
4323 have_include_file, have_core_file in favor of target_has_stack,
4324 target_has_memory, etc.
4326 * Modularize the breakpoint interface.
4327 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4328 a breakpoint instruction.
4329 breakpoint.c: struct breakpoint's shadow_contents now sized as
4331 (insert_breakpoints): Vector to target to install breakpoints.
4332 (remove_breakpoints): Vector to target here too.
4333 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4334 sparc-tdep.c (single_step): Use new breakpoint interface for
4335 the single-step breakpoints.
4336 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4337 New file, contains routines to insert and remove breakpoints by
4338 reading out the old contents and later replacing them. This is
4339 how ptrace breakpoints work, and many remote systems as well.
4341 * tm-vxworks68.h: New config file, overrides a few things for
4342 Wind River's preferences.
4344 * target.h: New file, for transfer vector used to talk to the
4345 inferior (child, attached, core, exec, remote, etc). All accesses
4346 to the thing being debugged should come through these vectors.
4347 target.c: New file, routines to handle transfer vector.
4348 (various files): Add transfer vectors XXX_ops for the various
4349 targets and pseudo-targets (core files, etc) we support.
4351 * breakpoint.c (bpstat_stop_status): Further explorations of
4352 watchpoints and why things don't work all the time.
4353 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4355 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4356 the local gdbinit if it doesn't already have it.
4358 * core.c (core_ops): add and install.
4359 Allow core debugging without exec file.
4361 * dbxread.c (free_and_init_header_files): Merge two fns.
4362 (end_symtab): Free named symbol table when a new version comes in.
4363 (read_dbx_symtab): Relocate all kinds of symbols with base
4364 address. First step toward handling different text, data, bss
4366 (add_file_addr_command): Renamed add_file_command.
4367 (add_file_command): Vector to remote handler.
4368 Add "load" as an alias for "add-file" command.
4370 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4371 non-returning functions.
4373 * exec.c: Add exec_ops, and push it as a target when an exec
4376 * infcmd.c (run_command): Pass executable file name and arg list
4377 separately when starting an inferior. Permit "run" when no exec
4378 file is specified, for VxWorks.
4379 (detach_command): Move to child_detach in inftarg.c.
4381 * inftarg.c: New file. Unix-child-specific routines, and the
4382 child_ops structure.
4384 * inferior.h (registers): Export "registers" as the way for
4385 target dependent register handlers to find gdb's local copy of
4386 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4387 since it is now used by places that want wait_for_inferior to
4388 handle the grunge but want to see every trap from the inferior.
4390 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4391 Eliminate remote_debugging hooks in terminal handling.
4393 * infrun.c: Replace start_inferior with child_create_inferior.
4394 Move all the hair of Unix shells and ptrace idiosyncracies into
4395 child_create_inferior, so remote handlers don't have to deal.
4396 Remove running_in_shell. Rename stop_after_attach to
4397 stop_soon_quietly, and use it in a few other places where we want
4398 to just call wait_for_inferior and get control back on the first
4399 trap. trap_expected now never takes a value > 1.
4400 (init_wait_for_inferior): Initialize static vars when a new
4403 main.c (gdbinit): Add new hook for .gdbinit file name, let
4404 it be overridden by config files as GDBINIT_FILENAME.
4405 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4406 Both of these are used for VxWorks gdb.
4408 mcheck.c: rename include file "gmalloc.c" to avoid problems
4409 with system include file "malloc.c".
4411 param-no-tm.h: New include file, same as param.h but does not
4412 include the default "tm.h" file. This is used in files where
4413 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4415 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4417 remote-vx.c: New file, VxWorks remote debugging support. Uses
4418 RPC routines that are shared with the target system, in directory
4421 remote.c: Vectorize remote interface.
4423 source.c: Globalize source_path, and make an alias "l" for "list"
4424 since we now have the "load" command.
4426 sparc-xdep.c: Use new param-no-tm.h.
4428 symmisc.c (free_named_symtab): Add new function from Wind River.
4429 However, ifdef it out for now while we think about what it should
4432 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4434 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4435 non-Unix-children handle this with their own code in the target
4438 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4439 source and target lists. Add vx-share to default list of include
4440 directories. Add new files to src and target lists: mem-break,
4441 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4442 ${srcdir} versions of munch and createtags are used.
4444 * valops.c (find_function_addr): Split out of call_function.
4445 (call_function_by_hand): Rename call_function; this function
4446 calls functions in the target by laboriously patching the target
4447 word-by-word with the right stack, args, regs, etc.
4450 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
4452 Handle AMD 29000 a bit better.
4454 * remote-eb.c (readchar): Mask received char log to make it readable.
4455 (remote_start): Pass arguments down to executing program.
4456 Make startaddr unsigned.

4459 infcmd.c (run_command): Pass args down to start_inferior.
4461 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
4462 the target object file format.
4463 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
4465 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
4466 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
4468 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
4470 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
4471 * TODO: We did a few things, we have more to do though.

4474 * inflow.c (inferior_died): Clear deferred stores.
4476 * Debug problems with dummy frames and calls to the inferior.

4478 * sparc-tdep.c (do_restore_insn): Simplify.
4479 (sparc_frame_find_saved_regs): Simplify and fix what we find.
4480 (sparc_push_dummy_frame): Simplify and fix what we push.
4481 (sparc_pop_frame): Slightly more hair here, deciding whether
4482 we are restoring a saved PC or returning to a return address in %i7.
4483 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
4485 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
4486 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
4487 * obstack.h (chunkfun): ditto.
4488 * defs.h (xmalloc, xrealloc): ditto
4490 * utils.c (quit): Grab the terminal from the child if necessary.
4492 * inflow.c (term_status_command): Rename to term_info, change
4495 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
4496 (is_delayed_branch): Speed up.
4497 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
4498 Still missing some float ops, and needs testing.
4500 * Support for input and output radixes other than base 10
4501 * defs.h (input_radix, output_radix): Declare.
4502 * expread.y (yyparse, parse_number): Handle changes of input
4503 radix, and ambiguous names-or-numbers in radixes >10.
4504 * printcmd.c (print_scalar_formatted): Print formatted hex
4505 numbers in varying column widths.
4506 * valprint.c (val_print): Use output_format to print scalar ints.
4507 (set_input_radix, set_output_radix, set_radix): Create.
4508 (set_output_radix): Set output_format from output_radix.
4509 (_initialize_valprint): add `set radix' but leave the others off.
4511 * main.c (execute_command): Let stupid questions be turned off.
4512 (_initialize_main): Handle "set stupidity", etc.
4514 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
4515 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
4517 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
4519 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
4520 bfd stuff is still screwed up, but with some manual work, it
4523 * breakpoint.c (bpstat_do_actions): Start over if a command
4524 proceeds the inferior, since the inferior will have stopped and
4525 will need to have its new stop-actions taken care of.
4527 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
4528 compiler fits, simplify it.
4530 * gdb.texinfo (directory command): Doc new dir command.
4531 source.c (directory_command): "dir" now puts things on the front
4532 of the path, moves dups up front, and handles multiple names
4533 on the command line, inserting each one in order. It also
4534 blows away cached line and full_filename info.
4536 * stack.c (backtrace_command): Skip "more stack frames follow"
4539 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
4540 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
4541 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
4542 The only odd one was Gould NP1, which had defined vprintf to
4545 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
4546 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
4547 variable, inspect_it.
4548 valprint.c (print_string, val_print): Use the global inspect_it
4549 to indicate whether to print in Epoch style or normal style.
4551 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
4553 * printcmd.c (call_command): add an alias for the "print" command
4554 which runs expressions and doesn't print the result if void.
4555 (print_command_1): implement it.
4557 * command.c: Remove #if 0'd code. Initialize all the fields
4558 in add_cmd (). Rename do_nothing_command to
4559 not_just_help_class_command, and make it externally visible.
4560 command.h: add user_commands to struct.
4561 * main.c (define_command): Don't overload c->function with a char
4562 string as well as a function pointer.
4564 * eval.c (evaluate_subexp): Reinstall tiemann changes to
4565 calling convention of value_struct_elt () that got dropped in
4568 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
4569 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
4571 * tm-sparc.h (POP_FRAME): replace some constants with defines.
4573 * sparc-xdep.c (store_inferior_registers): defer stores to regs
4574 until a good time (e.g. when we are about to run the child),
4575 saving ptrace calls.
4576 * infrun.c (proceed): handle DO_DEFERRED_STORES.
4577 * tm-sparc.h: define DO_DEFERRED_STORES.
4579 * sparc-xdep.c (store_inferior_registers): when storing float
4580 registers, don't store stack regs too. When storing the SP,
4581 however, DO store the stack regs too. This fixes a bug in which
4582 the dummy frame is not recognized when a call_function finishes,
4583 because its frame pointer (in the stack regs) was never
4585 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
4586 even though we don't know how to read them from an inferior.
4587 valops.c (call_function): Comment about storing SP.
4589 * infrun.c (save_inferior_status): Save away the original bpstat
4590 chain so it can be restored later. Install the copied version for
4591 use by whoever saved the status. It will be blow away by
4592 restore_inferior_status, and the original chain restored. This is
4593 important for people who have pointers into the original.
4595 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
4596 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
4597 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
4600 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
4602 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
4603 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
4604 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
4606 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
4608 * Merge Mike Tiemann's multiple inheritance changes from Sun.
4609 Store the baseclasses in a type struct starting from array element
4610 0 rather than from the unusual array element 1.
4612 dbxread.c: the above.
4613 (virtual_context): Add
4614 Read new debug information about which virtual function table
4615 a virtual function is from, and store it in fn_field.fcontext.
4617 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
4618 TYPE_FN_FIELD_STATIC_P.
4620 symtab.c: the above.
4621 valops.c: the above. Handle pointer casts of object *'s.
4622 (search_struct_method): Add.
4623 (value_struct_elt): First arg is now a pointer to a value, and is
4626 valprint.c: the above.
4627 values.c (value_virtual_fn_field): Add type arg. Handle
4628 offsetting to the proper object when calling virtual fns.
4630 (baseclass_addr): Add valuep arg.
4632 * README: Document the current state of BFD config (missing).
4633 * TODO, ChangeLog, Makefile.dist: Roll version.
4634 * WHATS.NEW: Add summary of changes since 3.5.
4636 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
4638 * dbxread.c (read_struct_type): Clear bit vectors whenever
4640 symtab.c (B_CLRALL): define.
4642 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
4643 using == rather than =. Huh... This fixes the dreaded problem
4644 wherein builtin_type_int becomes TYPE_CODE_FLT.
4646 * core.c (info_files): Show the inferior pid.
4648 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
4649 already knows how to look in the source directory.
4651 * Remove psymtab hair from many places. Remove duplicated code
4652 for searching symbol tables. Hide psymtabs from most places.
4653 Make it fast to get from a psymtab to its symtab.
4655 blockframe.c (blockvector_for_pc): Remove psymtab hair.
4656 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4657 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4658 dbxread.c: export psymtab_to_symtab, make it work if called N times.
4659 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
4660 new symtab completely. New psymtabs get symtab pointer
4661 initialized to zero. Remove MI warning printf.
4662 symtab.h: Comments. Add psymtab to symtab pointer.
4663 (PSYMTAB_TO_SYMTAB): New macro.
4664 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
4665 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
4667 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
4669 (print_frame_info): Avoid special-casing symbols that have not yet
4672 * source.c (open_source_file): Quick path if we have already
4673 located the source file by its full name.
4675 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
4676 find_pc_psymtab. When a name is found in the misc function
4677 vector, search the symbol table for its mangled name, not the
4678 name that the user typed.
4680 * bfd.h: Fix missing comment terminators, make #endifs match.
4682 * valarith.c (value_less): Handle unsigned int comparisons.
4683 Add FIXME about pointer compares, which assume host and target
4684 pointers are the same.
4686 * command.c (do_nothing_command): lint
4687 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
4688 fix comments on debug symbol format for visibility. Actually set
4689 visibility of symbols.
4690 main.c (echo_command): lint; use <readline/history.h>.
4691 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
4692 obstack.h (_obstack_blank): Rearrange pointer math to avoid
4693 pointing past end of allocated memory; saber complains.
4694 obstack.h: Declare the external functions that we use.
4695 valarith.h: use <string.h>
4696 solib.c (solib_add): lint.
4698 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
4700 * main.c (initialize_main): Default info_verbose to off, now that
4701 symbol reading is fast.
4702 (quit_command): Avoid clobbering exec_bfd while quitting.
4704 * Initial BFD (binary file diddling library) merger:
4705 coffread.c: Change AOUTHDR to struct exe_hdr.
4707 core.c: initialize initialized data at compile time.
4708 (core_file_command): Move from coredep.c, convert to bfd.
4709 (xfer_core_file): Convert to bfd.
4710 exec.c (exec_file_command): use bfd routines.
4712 mips-tdep.c: Remove exec_file_command and friends.
4715 * coredep.c: (fetch_core_registers) Convert core_file_command to
4716 fetch_core_registers.
4717 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
4719 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
4720 (my_bfd_read): More bogosity, which I don't think we call.
4721 (program_name): Remove this atrocity asap!
4723 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
4726 values.c: allocate_repeat_value was not clearing the
4727 optimized_out field.
4728 (value_static_field): minor stylistic fix (wrong macro was used).
4729 valops.c (value_struct_elt_for_address): didn't work for C++
4732 * signame.c (_initialize_signame): Initialize signal names once.
4734 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
4735 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
4736 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
4738 * remote-eb.c: Support user-settable baud rates on the serial port.
4740 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
4742 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
4744 * tconfig/sun3os4: Remove warning about native assembler,
4745 since it also occurs in the xconfig file.
4747 * findvar.c (registers): Allocate some slop after `registers'
4748 to prevent stray accesses from trashing the next variable.
4750 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
4751 on the sun-3, by changing the #ifdef from `sun3' (which is not
4752 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
4753 vars, which happened to follow `registers' in the executable.
4755 * readline/history.c (history_search): Heed gcc-2's advice
4756 and parenthesize && inside ||).
4758 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
4759 tm-29k.c: Insert FSF copyright headers.
4761 * remote-eb.c: Better comments.
4763 * Makefile.dist: Update to 3.91.6.
4764 * TODO: note PREPARE_TO_STORE problem.
4766 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
4768 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
4770 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
4772 * infrun.c (wait_for_inferior, at end): Don't set up
4773 prev_* if the inferior no longer exists.
4775 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
4776 CANNOT_EXECUTE_STACK.
4777 valops.c (call_function): Use it.
4779 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
4781 * inferior.h (PC_IN_CALL_DUMMY): New macro.
4782 infrun.c (wait_for_inferior, 2 places): Use it.
4784 * values.c (value_being_returned): Only use
4785 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
4787 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
4788 right thing for remote-eb.c.
4790 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
4791 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
4793 * blockframe.c: Put get_frame_saved_regs inside #if !defined
4794 (FRAME_FIND_SAVED_REGS).
4796 * findvar.c ({fetch,store}_registers): Check for
4797 REMOTE_{FETCH_STORE}_REGISTER macro.
4799 * findvar.c (get_saved_register): Add argument lval and
4800 change meaning of argument addr.
4801 findvar.c: Change calls to get_saved_register to reflect
4802 new calling convention.
4803 valops.c (value_assign): Use get_saved_register instead of
4804 find_saved_register.
4806 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4808 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
4809 an (uninitialized) pointer to one. Use "&" when passing it
4812 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4814 * coffread.c (getfilename): Use DGUX x_offset and x_name if
4817 * coffread.c (symbol_file_command): Put semicolon after
4819 Put safe_to_init_tdesc_context in #if defined (TDESC).
4820 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
4821 coffread.c: #include <sys/stat.h>.
4822 (read_coff_symtab): Typo: in_source_files -> in_source_file.
4823 Add missing ')' in check for "lc%" and friends. Remove
4825 Declare read_one_sym() at top of file.
4826 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
4827 MC68WRMAGIC can have the same value without causing a duplicate
4830 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
4832 * Allow a Makefile to be built without building the
4833 tm and xm file links that screw up builds in subdirectories.
4834 This is done with `config.gdb none', then you can do things
4835 like `make gdb.tar.Z'.
4836 * tconfig/none: Config file for no target system
4837 * xconfig/none: Config file for no host system
4838 * config.gdb: If no TM or XM files are called out by the
4839 host or target file, don't make links for them.
4841 * cplus-dem.c: Add documentation.
4843 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
4844 simple error, so the user's gdb doesn't crash due to some object
4845 file problem (e.g. somebody is rebuilding the file out from under
4848 * printcmd.c (print_address_symbolic): demangle the symbol.
4850 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
4851 Motorola copyrights in it. Make "make gdb.tar.Z" work.
4852 (alldeps.mak): sort and uniq all results from this; duplicates
4853 hose gdb.tar.Z link building. Remove RCS files from
4854 tconfig and xconfig. Add config files for sun386. Add
4855 a few odd files to OTHERS and HFILES.
4857 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
4859 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
4860 Roll version number to 3.91.5. Make lint work in bindir.
4862 * README: Document cross-debugging and new file structure.
4864 * blockframe.c: Lint. Include "value.h" to declare read_register.
4865 (find_pc_partial_function): remove duplicate line.
4867 * command.h: Lint. Declare error_no_arg and dont_repeat.
4869 * tm-news.h: Remove inadvertently duplicated stuff.
4871 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
4872 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
4874 * config.gdb: Allow `config.gdb host target' form. Clean
4875 up previous change that printed bogus messages when you just said
4878 * core.c: #include "command.h" for lint.
4881 * main.c: Remove some casts of enums. Lint.
4888 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
4890 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
4891 read it from memory. This will allow us to save ptrace calls
4892 eventually. Changed caller single_step too.
4894 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
4895 that we aren't going to use, saving many ptrace calls, especially
4896 when watchpointing or single stepping. Use some #define's for
4898 (store_inferior_registers): Ditto.
4899 (core_file_command): Use some #define's for constants.
4901 * tm-sparc.h: Add #define's for some register numbers, so we
4902 can eliminate the use of random constants in sparc-xdep.c.
4904 * stack.c (frame_command, print_frame_info, up_command,
4905 down_command) Remove frame_changed, since it
4906 causes a bug and doesn't seem to do anything useful. In some
4907 places it was used as a flag, in others as a stack level (?).
4909 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
4910 default is to use the portable (vprintf) version rather than the
4912 * xm-news.h (MISSING_VPRINTF): Add.
4914 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
4916 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
4918 * Remove stuff that forces -Bstatic linking of gdb, and warnings
4919 about linking debugged programs -Bstatic in the sun?os4 config
4920 files in tconfig and xconfig subdirectories.
4922 * main.c (main): Remove unreached exit(0) now that we exit
4925 * Create TODO file for online bug list. There are too many
4926 "little" bugs to keep track of on paper.
4928 * Change Projects file to refer to bug-gdb@cygnus.com
4929 rather than kingdon@ai.
4931 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
4933 * Makefile.dist (VERSION): 3.91.4 now.
4935 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
4936 (condense_misc_bunches): Add sanity check that misc_count is
4937 the same as the number of symbols in the bunch.
4939 * coffread.c: rename init_misc_bunches. Pass an argument
4940 to condense_misc_bunches (a zero).
4942 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
4943 every time we are called; don't rely on our caller to do it.
4944 (add_file): Remove call to init_misc_bunches.
4946 * mipsread.c: Only warn, don't error, if unknown symbol types.
4947 This keeps an old gdb from falling on its face if it sees newly
4948 extended symbol info. Rename init_misc_bunches.
4950 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
4952 * Merge in changes from Per Bothner for DECstations and other
4953 MIPS stuff. The rest is Bothner speaking:
4955 The next message is a merger of Alessando Forin's mips port with
4956 mine. I've tried to use my good if biased judgment to get
4957 the best of both. It *does* need testing.
4959 Some of the changes are general, *not* mips-specific.
4962 Didn't believe in little-endian bit order.
4963 There are still inconsistencies about whether flags
4964 like BITS_BIG_ENDIAN are integer (#if ...) or
4965 boolean (#ifdef ...). I tried to paper over them.
4967 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
4968 Moved some misc_function code that was common to
4969 {dbx,coff,mips}read.c to symtab.c.
4970 In the process, I think I cleaned things up a bit.
4971 At the same time, moved obsavestring and obconcat to symtab.c.
4974 Removed obsolete condense_addl_misc_bunches (use
4975 condense_misc_bunches(1) instead).
4978 Needed to include <sys/dir>, at least on DECstations.
4980 valops.c, mips-tdep.c, tm-mips.h:
4981 Added PUSH_ARGUMENTS macro to support funny argument-pushing
4982 conventions (when STACK_ALIGN is insufficient).
4983 Needed on mips, where doubles need 8-byte alignment,
4984 but ints only need 4.
4987 Removed cruft that was not being used.
4988 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
4991 Print $ before register-names (I think that makes things a little
4993 Never print two instructions, even if one delays.
4994 Removed hex-disassemble set_cmd. (This is not mips-specific,
4995 so I think the argument is whether it is generally worthwhile or not.
4996 I'm inclined to think not, given how easy it is to
4997 convert between radixes in gdb.)
5000 This is basically Alessando's code.
5001 It doesn't use obstacks; I changed it to use obstacks
5002 in a few minor places where using malloc causes a
5003 memory leak. (Probably, more places could/should be changed.)
5004 I added record_misc_function where it was missing.
5005 In symbol_file_command and add_file_command, I tried
5006 to make the code consistent with more recent versions.
5007 Minor sylistic changes in parse_procedure.
5008 Make a .gdbinfo. psuedo-symbol point back to the real
5009 procedure symbol (using the isym field).
5012 This is basically from my port, but with a lot of details
5013 and a number of routines merged in from Alessando's version.
5014 I basically used my code "raw" backtrace (use heuristics
5015 from the actual code, rather than symbol table info) - though
5016 the idea is Alessandro's. I feel my code is a little cleaner
5017 here, particularly in being a little more flexible, such as being
5018 able to handle gcc-produced code (which it now can).
5019 It also doesn't do frame caching (which is not useful
5020 more recent gdb versions).
5021 I also used my code for push_/pop_dummy, more or less.
5022 I tried to incorporate AF's code for testing sigtramp
5023 while backtracing; I probably got it wrong.
5024 Added mips_print_register, which tries to scrunch as much
5025 information as possible on a screen...
5026 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5027 under mips-pinsn.c), I don't see anything mips-specific here,
5028 and I don't see it being all that useful anyway.
5031 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5032 Use more register names (rather than hard-cases numbers).
5034 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5036 * Hack up 3.90.11 changes:
5038 * Makefile.dist (depend): parameterize $(GCC).
5039 Add solib.c and solib.o.
5040 (readline): Fix vpath for both absolute or relative SRCDIR.
5042 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5043 Also, let the part I didn't understand at least compile so
5044 I can test the rest. FIXME.
5046 * dbxread.c: Fix thinko using strcmp.
5047 (init_psymbol_list): declare static.
5048 (partial_symbol_file_open): Comment cleanups better, avoid
5049 cleaning up the string table since the caller will do that.
5050 Move the stat for mod time into symbol_file_command, temporarily.
5051 (There should be a mod time for each symbol file, eventually,
5052 to control its rereading. FIXME.)
5054 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5055 SunOS, which gives error for shared libs otherwise. (From
5056 Schaefer, probably FIXME needs work for portability.)
5058 * solib.c: Move #include "param.h" to work.
5059 Lowercase all the Uppercase Letters In the Messages.
5060 (find_solib): Clean up inferior_so_name for debug printouts.
5061 Allow no argument, to mean all shared libraries.
5063 * symmisc.c: include param.h to get CLEAR_SOLIB.
5065 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5067 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5068 to 3.90.11. ChangeLog entries below are from this.
5070 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5074 * Makefile.dist (HFILES): Add tm-sunos.h.
5076 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5080 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5082 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5084 * sparc-opcode.h Added single-operand version of rett.
5086 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5088 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5089 Put parens around gcc_p in expansion.
5091 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5093 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5095 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5097 * Changes for Sun shared libraries:
5098 blockframe.c (find_pc_partial_function): If a non-text symbol
5099 is found, set *address = pc - FUNCTION_START_OFFSET.
5100 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5101 Disable breakpoints instead of giving an error.
5102 source.c (select_source_symtab): Initialize cs_pst.
5103 symmisc.c: Call CLEAR_SOLIB if defined.
5104 symtab.h: Make text{low,high} CORE_ADDR not int.
5105 (psymtab): New field addr.
5107 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5108 (record_misc_function): Give correct type for N_DATA symbols.
5109 (condense_misc_bunches): do "misc_function_count = j" regardless
5111 Take code which is shared between symbol_file_command and
5112 add_file_command and put it into partial_symbol_file_{open,read}.
5113 Split add_file_command into add_file_command and add_file.
5114 Make psymtab_to_symtab read in the string table if the file
5116 Two new parameters to read_dbx_symtab and start_psymtab.
5117 tm-sunos.h: New file.
5119 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5121 * infcmd.c: Change cont_command to continue_command and "cont"
5124 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5126 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5128 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5130 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5131 size 1,2,4,8 rather than size < 8.
5133 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5134 as necessary, not just once.
5136 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5138 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5140 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5142 * tm-news.h: Add CALL_DUMMY_*.
5144 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5146 * config.gdb: In list_host, list_target, use ${i}, not $i.
5148 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5150 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5152 * sparc-opcode.h: Change all store floating-point state register
5153 instructions to have the right match & lose fields.
5155 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5157 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5159 config.gdb: If srcdir != ., create readline directory and
5160 copy a makefile into it.
5162 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5163 consistency with POSIX.
5165 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5166 when we exit its exp_valid_block.
5168 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5170 * Makefile.dist: Bump version to 3.91.3.
5172 * Clean up handling of breakpoint commands (somewhat).
5173 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5175 inferior.h: Add breakpoint_proceeded to inferior status struct
5176 and globals; save it and restore it.
5177 (clear_breakpoint_commands): Cleanup, remove old #define.
5179 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5180 (save_inferior_status, restore_inferior_status): handle it also.
5181 (proceed): Remove earlier code that set breakpoint_proceeded.
5182 It is now set only in clear_proceed_status.
5183 (clear_proceed_status): Cleanup, use bpstat_clear rather
5184 than clear_breakpoint_commands. No callers need the stop_bpstat
5185 between clear_proceed_status and proceed.
5187 infcmd.c: Add breakpoint_proceeded definition and comment.
5188 (cont_command, jump_command, signal_command): Move call to
5189 clear_proceed_status right next to call to proceed.
5191 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5192 caller's argument while running down the chain of breakpoints.
5193 Use new variable "breakpoint_proceeded" to determine when
5194 a command that it executes moves the inferior past the
5196 (bpstat_clear): Handle NULL argument.
5197 (bpstat_clear_actions): Avoid useless call to
5198 breakpoint_auto_delete.
5199 (delete_breakpoint): Clean up bpstat's that are pointing to
5200 the deleted breakpoint from the stop_bpstat chain.
5201 (breakpoint_auto_delete): Simplify.
5203 * Clean up handling of EOF, error on stdin, etc. This was
5204 prompted by a network problem that caused gdb to go into an
5205 infinite loop filling up its malloc'd memory.
5207 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5208 not clear_breakpoints_commands, which is now gone.
5209 (main): If command_loop returns (e.g. from EOF on stdin), do
5210 a quit_command (looping back to command_loop if quit_command
5211 doesn't really quit).
5212 (command_loop): check result from command_line_input and
5213 exit if it returns NULL, rather than passing the NULL to
5215 (gdb_readline): Free malloc'd result space before returning
5218 * utils.c (query): Handle C-d to mean "yes", just as if the
5219 input was not a terminal. Also avoid infinite loop if EOF
5220 occurs in mid-input-line before newline. This allows
5221 query to be used at EOF on stdin with reasonable results.
5223 * infrun.c (proceed): Set breakpoint_proceeded.
5225 * values.c (value_as_long): Avoid infinite recursion for enums.
5226 (_initialize_values): Fix typo in help msg (kingdon).
5228 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5229 RL_LIB for linking. This allows -lreadline for linking
5230 and nothing for dependencies, once readline is a real library.
5232 * config.gdb: Jim Kingdon: give useful error message if the
5233 host or target type is not recognized.
5235 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5236 it just defines it. Dumb, but deal with it.
5238 * Jim Kingdon suggests:
5239 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5241 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5243 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5245 * Clean up Bothner's changes.
5247 * blockframe.c (clear_pc_function_cache): New function.
5248 * blockframe.c: remake cache_pc_function_* static.
5249 * dbxread.c (symbol_file_command): remove references to
5250 cache_pc_function_* variables.
5251 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5252 * printcmd.c: Avoid kludging a global variable (addressprint)
5253 to avoid printing the address of a string twice. Instead,
5254 pass the format letter 's' down low enough that it can be seen
5255 to avoid this problem.
5256 (print_formatted): Pass format arg to value_print.
5257 (restore_addressprint): Remove function.
5258 (do_examine): Avoid hacking addressprint, cleanups and such.
5259 (print_frame_args): Add a comment to a Bothner change.
5260 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5261 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5262 to wipe out the values cached in blockframe.c.
5263 * symtab.c (find_method): Add comment saying how big you must
5264 allocate to be "big enough". Per being terse again.
5265 * valprint.c (val_print): Handle format letter "s" to print
5266 strings without addresses. Add comment to vtbl printing code
5267 which casts with wild abandon. Rearrange reference-printing
5269 @0xaddr: value (print w/addressprint)
5270 value (print w/~addressprint)
5271 @0xaddr (parameter lists w/addressprint)
5272 or nothing (parameter lists w/o addressprint)
5274 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5276 * Merge more changes from Per Bothner:
5278 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5279 annoying) that I tried to improve it. Here are my suggestions.
5281 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5284 Do automatic de-reference when taking the address of a reference.
5286 Don't deref_ref when printing parameter lists.
5288 More attempts at treating refernences properly.
5290 In val_print, if deref_ref==0, don't print dangling " = ".
5292 Add COERCE_REF macro, which de-references an REF.
5294 * Merge changes from Per Bothner:
5296 * Fixed (Sony news)-specific configuration problems.
5297 * Fixed other problems with using vanilla pcc and libc (enum problems;
5298 assumption that vsprintf exists).
5299 * Some major speed-ups (finc_pc_partial_function now caches a match;
5300 parsing avoids duplicate symbol_lookup calls).
5301 * Changed handling of baseclasses (no longer use baseclasses field
5302 of struct type, use the first n_baseclasses fields instead).
5303 * Various minor changes/fixes, most C++-related.
5306 Cache the most previous match from find_pc_partial_function.
5307 (Save both low and high ends of matching function's pc range.)
5308 This speeds up the loop of infrun.c:wait_for_inferior quite
5309 a bit, and makes step/next commands much zippier.
5311 Added an enum->int cast (otherwise, some compilers barf).
5313 No longer set baseclass offset to 0, since multiple
5314 inheritance now mostly works.
5315 Added a number of casts, to shut up compiler warnings
5316 (after stabs where made enums, not ints).
5317 When discarding a symbol table (in symbol_file_command),
5318 must clear the cache introduced in blockframe.c.
5319 Don't convert $vtbl_ptr_type to vtbl any more.
5320 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5321 Mask off sign bit emitted by g++ for virtual table offset.
5322 Set voffset to -1 (not 1) for static member functions.
5324 Changed parsing/lexing of names to avoid doing symbol lookup twice
5325 (once when lexing to determine symbol class, once for real).
5326 Now only call symbol_lookup once. Fields of 'this' win especially big.
5328 Subpress printing addr twice in the case of 'x/s addr'.
5330 lookup_basetype_type is no longer used.
5331 Add find_methods as recursive helper function to decode_line_1.
5332 This allows multiple inheritance to work.
5333 Also, once one or more matches has been found, do not look in
5334 base-classes. (Baseclass methods would be overridden, anyway.)
5336 Removed baseclasses array in struct type.
5337 Instead of using baseclasses[i], use fields[i-1].
5338 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5339 Changed sign convention of voffset (previous was inconsistent).
5341 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5343 Used to assume existence of vsprintf. Re-written to not need it
5344 if HAVE_VPRINTF is undefined.
5346 typecmp was too pessimistic. Made it less so.
5348 Don't print space after address.
5349 If vtable points to a misc symbol (with 0 offset), print it,
5350 since that indicates the actual class of the object.
5351 Changed ype_print_derivation_info to use new inheritance
5352 scheme (without baseclasses vector).
5354 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5355 Also, changes needed because TYPE_BASECLASSES were removed.
5357 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5359 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5362 If there is no path set, and the symbols don't indicate what directory
5363 a file was compiled in, look in the current directory. But either
5364 a path or a known compilation directory will prevent this.
5367 Three independent bug fixes:
5368 * Remove the #if 0 block that breaks some stuff.
5369 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5370 adapt gdb to either SunOS 4.0.* or 4.1.
5371 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5374 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5377 (type_print) Demangle the name being printed.
5378 (type_print_base) Handle botched demangling without coredump (tiemann).
5381 (check_stub_method): Document routine.
5382 (tiemann) fix bug for no-arg functions
5383 Avoid clobbering beyond end of malloc'd storage.
5384 Terminate the argument list properly.
5386 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5388 * Changes merged by John Gilmore:
5391 In breakpoint_1, use new print_address_symbolic instead
5392 of find_pc_partial_function. (This forces use of assembler-level
5393 addresses, and avoids misleading non-mangled source-level names.)
5395 Generalize ansi argument such that -1 means skip arglist totally.
5396 Removed global variable print_ansi_qualifiers (which made
5397 code non-reentrant), in favor of extra explicit arguments
5398 to internal routines.
5400 Add new helper function print_address_symbolic.
5401 Use find_pc_misc_function instead of find_pc_partial_function
5402 (since we want assembler-level symbols here).
5404 Print unknown function as just "f (...)", not "f (...) (...)".
5405 Use new fputs_demangled explicitly.
5407 Fixed a typing violation (problem: value.h cannot be imported
5408 without renaming many variable in this file).
5409 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5410 decode_line_1: Moved forward some never-reached code.
5411 Made decode_line_2 skip function prologues correctly.
5413 fputs_filtered should not demangle by default.
5414 Add new fputs_demangled to demangle on demand..
5416 Change value_struct_elt to use value_primitive_field (using recursive
5417 utility function search_struct_field). This allows foo.bar to work
5418 for multiple inheritance (so far only for data fields).
5419 Change check_field in the same way (recursive helper function
5420 to support multiple inheritance).
5421 (Note: there are more of these problems that I haven't fixed.
5422 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5423 value_of_this: 'this' symbol name is now just "this", note "$this".
5425 Don't print static members.
5426 Avoid printing "members of <type>" if there are none.
5427 Simplified type_print_derivation_info by merging duplicate code.
5428 Remove useless blank lines in type_print_base (ptype command).
5430 Added declaration of new routine value_primitive_field.
5432 Added value_primitive_field which is generalized version of
5433 value_field that can handle multiple inheritance (non-zero offsets etc).
5434 Re-implemented value_field to call value_primitive_field.
5436 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
5438 * infcmd.c -- insert else to avoid 'delete env' coredump when you
5439 delete the whole environment. Karl Berry reported the bug.
5440 * source.c - fix openp to avoid //'s in filenames, which
5441 trigger an Emacs bug causing it to not be able to find files
5442 when running gdb in a window.
5443 * dbxread.c - zap the #if 0 that botches the add-file code.
5444 It seems to work a lot better without all the code commented out.
5446 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
5448 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
5451 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
5453 * Makefile - added a ${CFLAGS} to a couple of entries,
5454 added remote-sa.sparc.c
5455 * added remote.sa-sparc.c, a modification of remote.c
5456 which conducts a dialog directly with the SparcStation prom.
5457 * breakpoint.c, infrun.c, sparcdep.c added
5458 remote_insert_breakpoint(), and remote_remove_breakpoint()
5459 to breakpoint.c instead of directly writing breakpoint instructions.
5460 * sparcdep.c on remote_debugging,there is no need
5461 to remove signle step breakpoint instructions.
5462 * main.c added "-epoch" flag and "int epoch_interface" to main.c
5464 * printcmd.c - epoch interface sends lisp expressions to open up
5465 epoch windows on inspection.
5466 * valprint.c - added arrayprint, and addressprint and made adding
5467 format controls easier
5468 * wait.h added a couple of undef's because we were getting
5469 complaints about WSTOPSIG and WTERMSIG begin redefined.
