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

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

270 (read_range_type): Rename MAX_OF_TYPE to MAX_OF_C_TYPE, etc.
271 #if 0 out its uses, though, since they set a dead value.
272 * coffread.c (end_symtab): Use allocate_symtab.
273 (process_coff_symbol): #if 0'd for functions and params as above.
274 (read_enum_type): Recognize Modula-2 BOOLEAN.
275 * symtab.c (add_param_to_type): #if 0'd function to add a
276 parameter type to a function type's field list.

287 * parse.c: New file with the common code remains of expread.y.
288 * parser-defs.h: New file with common declarations from expread.y.

347 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
349 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
350 entries are enclosed herein. Not all of these changes
351 have been merged into the master GDB sources -- check the
352 ChangeLog above here for the merge log.
354 Mon Jun 3 17:05:45 EDT 1991
356 m2-exp.y Created. Tested outside of GDB for a few days. Proper
357 operators were added, C specific operators and tokens
358 removed. yylex() revamped to some extent. Still things
359 missing from the grammar, such as sets.
360 Tested for two weeks in GDB v3.5.
362 Tue Jun 11 17:23:48 EDT 1991
364 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
365 so they are built-in. Sort of a hack.
367 Fri Jun 14 12:53:51 EDT 1991
369 m2-exp.y Added range checking for numeric constants. Any numeric
370 constant is assumed to be of builtin type INTEGER unless:
371 (1) it is octal or hexadecimal, in which case it is a
372 CARDINAL; (2) it is too big to fit into an INTEGER, in
373 which case it is a CARDINAL.
374 eval.c Added simple range checking for +, -, and * on integers.
375 Doesn't work very well for *, since 6 * 1,000,000,000 =
376 1,705,032,704, which fails the simple test of result >=
377 first_operand, no matter in what order the operands are.
379 Tue Jun 18 14:11:30 EDT 1991
381 Broke the parser into parts, one containing the C grammar and the other
382 containing code to be shared by all of the grammars.
384 The following files no longer exist:
389 The following files were added:
391 c-exp.y (The C grammar)
392 m2-exp.y (The Modula-2 grammar)
393 parser-code.c (Code that is shared by the above grammar)
397 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
398 now necessary to use the Bison compiler compiler, since it
399 will generate function/variable prefixes other than yy.
401 Tue Jun 18 16:47:49 EDT 1991
403 symtab.[ch] Added the external variable working_lang, than holds the
404 value of the current working language.
405 Added the ennumerated type language_mode, with the values
406 language_auto and language_manual, the former meaning that
407 GDB sets working_lang as needed, and the latter meaning
408 that the value of working_lang is totally under user
410 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
411 REAL, BOOLEAN and CHAR. Also added the type codes
412 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
413 utils.c Added set_language_command and show_language_command to
414 implement the GDB support commands "set language" and
416 expression.h A number of identifiers were added to the type exp_opcode
417 to facilitate Modula-2 builtin functions, integer
418 division, and array indexing.
420 Wed Jun 19 13:25:58 EDT 1991
422 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
423 if the language specified by working_lang requires the use
424 of strict typing of expressions. Eventually, even this
425 will be able to be changed by the user.
426 Added the macro RANGE_CHECK, which evaluates to non-zero
427 if the language specified by working_lang requires the
428 checking of a value against the domain of its type.
429 Eventually, even this will be able to be changed by the
431 language.[ch] Predicates involving types (simple_type, ordered_type,
432 same_type, integral_type, numeric_type, character_type,
433 boolean_type, float_type) are added. These predicates are
434 based on the current value of working_lang, and are handy
437 Wed Jun 19 15:39:34 EDT 1991
439 eval.c Added the function type_array_rank which computes the rank
441 valarith.c Added the funtion value_bool, which when given a integer
442 value.h value (ie. struct value *) as an argument, it returns a
443 boolean value (ie. struct value *) true if that integer
444 is non-zero, and a boolean value false otherwise.
445 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
446 will print out properly.
448 Wed Jun 19 16:36:34 EDT 1991
450 valops.c Added the function value_capitalize, which returns it
451 value.h argument capitalized if its argument is a lowercase
452 letter, or the argument unchanged if its argument is not a
454 valarith.c Added the function range_check_p, which returns non-zero
455 value.h if its value argument is between the integral bounds upper
457 Added the function range_check_enum_p, which makes sure
458 that its value argument is a valid member of the domain of
460 Added the function range_check_range_p, which makes sure
461 its value argument lies between the upper and lower bounds
462 of its type argument, which must be a ranged type.
463 Added the function check_array_index, which range and type
464 checks an index of an array.
465 Added the function value_multi_subscript, which computes
466 array[idx1,idx2...idxN], given a value array and an array
467 of values representing indicies.
468 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
469 unpack_long to work with TYPE_CODE_BOOL and
472 Wed Jun 19 18:04:08 EDT 1991
474 symtab.c Stored pervasive types in a structure and make
475 lookup_pervasive_type() a lookup function that was based
476 on working_lang. If lookup_pervasive_type() returned
477 non-zero, then that value was returned (a fix, since
478 before it simply wouldn't return the pervasive type.)
479 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
480 non-zero if the language specified by working_lang means
481 "conversion" when it says "cast".
482 valops.c Added the function value_real_cast(), which performs a
483 value.h *cast*, not a *conversion*, which is what value_cast()
484 does when it can. In particular,
485 value_cast(<float_type>,4) = 4.0, while
486 value_real_cast(<float_type>,4) = some mess.
487 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
488 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
489 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
490 and MIN on integral types. *NOTE*: These are currently
491 hardcoded to work only if there are 8 bits per storage
493 eval.c Made logical functions call value_bool to return a
494 properly typed boolean value, based on working_lang.
496 Thu Jun 20 11:55:27 EDT 1991
498 valprint.c Types now print out in a Modula-2 fashion. This works for
499 the cases when the type is printed out step-by-step, that
500 is, it doesn't work when the name of a structured type
501 (which includes the keyword "struct", etc.) is simply
503 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
504 since type specifications in C and Modula-2 are very
505 different. The C printing of a type is very recursive,
506 whereas in Modula-2 it is generally very simple. C has
507 type prefixes and suffixes, which have no real analogue in
508 Modula-2. Maybe type_print() should call a language
509 specific type printer. This is also advantageous if we
510 compile GDB to exclude some of the languages. We'll just
511 leave those functions out.
513 Thu Jun 20 16:57:10 EDT 1991
515 dbxread.c When reading the complete symbol table in (via
516 psymtab_to_symtab()), the number and types of function
517 arguments are added to a function type. define_symbol()
518 calls add_param_to_type() to accomplish this.
519 Assumption: when we come across a function definition
520 (N_FUN symbol with an 'f' or 'F' in the name), its
521 arguments will appear before another function definition.
522 When a function is found, a pointer to its type is placed
523 in the global in_function_type. Changes that
524 add_param_to_type() makes are to this global.
525 valprint.c The type of a function now includes (for Modula-2) the
526 types of its parameters.
527 eval.c Type checking and a check for the proper number of
528 arguments is now done for function calls. Not sure of the
529 impact this has on C++ member function yet.
531 Thu Jun 20 19:58:48 EDT 1991
533 valprint.c Rewrote the type printer. Broke it into two language
534 specific parts, adding the functions type_print_m2() and
536 An unfortunate consequence is this: if you debugging a C
537 program in Modula-2 mode (why?), info types does not work
538 well with regular expressions, since the types are printed
539 out in Modula-2 terminology, but stored in C terminology.
540 language.[ch] Added the functions new_type_last(), type_keyword(), and
541 type_sep() to aid in the printing of typedefs.
542 symtab.c Made the printing of typedefs as language independent as
543 possible through calls to new_type_last(), type_keyword(),
546 Fri Jun 21 11:50:26 EDT 1991
548 dbxread.c Check all incoming ennumerated types. If it looks like
549 Modula-2's BOOLEAN type, then change the type_code of the
550 type to TYPE_CODE_BOOL so we can process it as a boolean
552 valprint.c Replaced some of the 0x%x with calls to sprintf and
553 hexformat() in val_print().
554 language.[ch] Added the function hex_to_string(), which converts its
555 integral argument to a hexadecimal number (format is
556 language based) and returns the result as a string.
558 Mon Jun 24 12:25:07 EDT 1991
560 valprint.c Some functions call type_print_1() directly, instead of
561 value.h using type_print(), so they can specify where (column) to
562 print things. Since type_print() takes care of language
563 dependence, that needs to be called first. Added a
564 parameter depth to type_print() (so it is now like
565 type_print_1). Changed type_print to type_print_at, and
566 made type_print a macro that passes a depth argument of
568 symmisc.c Changed all calls to type_print_1 to calls to
570 Makefile.dist Made it possible to build GDB for a specific set of
571 depend languages. Do this by passing a definition for the macro
572 LANGS to make. LANGS should be a string containing a
573 space-separated list of language names (ie. LANGS="c m2").
574 The default is to build all languages. Note that grammar
575 files must follow the naming convention of <lang>-exp.y.
576 gdb.lang This holds the current value of the LANGS macro. It is
577 examined every time make is called, and is updated if
579 eval.c Added #ifdef _LANG_<lang> to these files.
580 expread.c Still need to add them to dbxread.c and coffread.c.
588 Mon Jun 24 16:33:11 EDT 1991
590 language.[ch] Added the functions hexformat_pre() and
591 hex_to_string_pre(), which take a prefix argument to
592 include in the format string. Thus, hexformat_pre("08") will
593 return "0x08x" (if the working language is language_c).
594 Made hexformat() and hex_to_string() calls to the above
595 with "" as the prefix argument.
597 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
598 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
599 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
600 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
601 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
602 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
603 valprint.c, vax-pinsn.c
605 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
606 calls to hexformat() and hex_to_string(). Format strings without
607 the leading "0x" were ignored.
609 depend Updated to take the above into account.
612 Tue Jun 25 15:27:18 EDT 1991
614 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
615 and type_check_t to keep track of the current state of
616 range and type checking.
617 main.c Added the variables range_mode, range_check, type_mode,
618 and type_check to record the current state of range and
619 type checking. Added initialization code to main().
620 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
624 Tue Jun 25 17:57:08 EDT 1991
626 dbxread.c process_one_symbol() updates the variable (enum language)
627 source_lang based on the extension of the filename
628 contained in the N_SO sybmol that started this symtab.
629 When end_symtab() is called, the value of source_lang is
630 put into the language field.
631 stack.c select_frame() sets working_lang (and possibly type_check
632 and range_check) to the language field of the symtab
633 associated with the frame that is selected if working_mode
634 is language_auto. If working_mode is language_manual, a
635 warning is printed and working_lang is not set.
636 language.c Added the function set_type_range(), which sets the value of
637 type_check and range_check (if their modes call for
638 automatic setting) based on the current value of
639 working_lang. A non-zero argument will cause the current
640 settings to be output.
643 Wed Jun 26 14:51:40 EDT 1991
645 eval.c Added range checks on assignment.
646 m2-exp.y Added the grammar for sets to the language. Currently,
647 these do not do anything except print an error message.
649 Wed Jun 26 17:01:04 EDT 1991
651 m2-exp.y Added the ability for parse_number() to parse negative
652 numbers. A global flag is set upon encountering a unary
653 minus. This was done to make, for example, 1 parse as a
654 CARDINAL, and not as an integer, per Wirth's examples in
655 Programming in Modula-2 ed.4.
656 valprint.c Added support for "set radix 2" by then setting
657 output_format to 't'.
658 eval.c Implemented range checking on subrange types. Added calls
659 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
660 Implemented MIN and MAX for ennumerated types. The
661 minimum value of an ennumerated type is defined by Wirth
662 as the first identifier, and the maximum as the last.
663 m2-exp.y Made octal numbers ending with "B" be characters and those
664 ending with "C" be numbers, per Wirth's book. (p. 34)
666 Thu Jun 27 14:11:52 EDT 1991
668 stack.c select_frame() now only sets working_lang, it does not
669 notify the user. If working_mode is language_manual, then
670 a warning is issued once.
671 main.c At the end of each call to execute_command(), working_lang
672 is checked against the local static (enum language)
673 current. If they differ and working_mode is
674 language_auto, the new settings of language, type and
675 range checking are printed out.
676 stack.c Modified frame_info() to include the language of the
677 current frame in the output of "info frame".
678 language.[ch] Added the function language_str() which returns the name
679 of the current language.
681 Fri Jun 28 15:33:14 EDT 1991
683 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
684 the language. INCL and DECL currently cause an error,
685 since sets are not implemented yet. INC and DEC are
686 implemented as PREINCREMENT/PREDECREMENT with one
687 argument, and as ASSIGN_MODIFY with two arguments.
688 eval.c Added type checking to the above cases.
689 value.h Added not_lval_constant to the lval_type ennumerated type.
690 not_lval_constant means that the value is a constant
691 value; that is 3 or 'a' or TRUE, not as in a constant
692 identifier. This is used to help coerce numbers such as 3
693 to either signed or unsigned numbers.
694 valops.c Added the function value_coerce_constants() which coerces
695 constant integers as following: if one is a constant and
696 the other is not, the constant's type is set to the type
697 of the other argument. If both are constants and one is
698 signed, the other is converted to a signed constant.
700 Sat Jun 29 17:26:29 EDT 1991
702 valarith.c Added a better range checker. It now checks range
703 (successfully) on integral operations [+-] (signed and
704 unsigned) for any C sized type. Still does not work well
706 int_in_size() returns an integer that is coerced to fit into
707 specified number of bytes.
709 Mon Jul 1 13:04:14 EDT 1991
711 language.[ch] Added the function binop_result_type(), which returns the
712 builtin (struct type *) type that would be the result of a
713 binop on the two values V1 and V2.
715 Wed Jul 3 19:22:53 EDT 1991
717 source.c Extended source_info() to include the source language in
718 the output from "info source".
720 Fri Jul 5 13:48:52 EDT 1991
722 utils.c Moved the support functions for the GDB set/show commands
723 dealing with language into language.c.
724 language.c Added the function language_info(), which displays info
725 about the current working language, type and range check
726 settings. Called via the GDB command "info language".
727 Added an initialization routine _initialize_language(),
728 that sets defaults for the language, type and range
729 variables and sets up the new GDB commands.
730 main.c Language setup moved to language.c.
733 Mon Jul 8 10:10:22 EDT 1991
735 valarith.c Debugged the range checker for arithmetic. Still does not
736 work for multiplication very well.
738 Mon Jul 8 12:40:37 EDT 1991
740 language.[ch] Added the function value_true() which returns non-zero if
741 its argument represents a boolean true value.
742 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
743 check the truth of an expression.
745 Thu Jul 11 12:51:34 EDT 1991
747 language.[ch] Added the predicate structured_type(), which returns
748 non-zero if the argument is a structured type.
749 Added the predicate pointer_type(), which returns non-zero
750 if the argument is a pointer type.
751 eval.c Added the ability to do addition and substraction on
752 pointers and integers. This case simply bypasses the
755 Thu Jul 11 14:41:42 EDT 1991
758 Added the symbol N_DEFD (0x4a) which is a definition
759 module dependency that is used by the GNU Modula-2
760 compiler and the linker. It is not important to GDB,
761 except that [dbx|coff|mips]read.c should ignore these
764 Fri Jul 12 16:07:00 EDT 1991
766 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
767 0 in val_print(). Also added statements to the else part
768 to coerce type (argument to val_print) to a pointer type
769 if it is an "array of unspecified length".
770 valops.c Added the function value_m2_string(), which returns a
771 (value) value which is a constant string, whose type is
772 (ARRAY [0..n] OF CHAR). The length field of the type
773 structure is set to zero, so it will be interpreted as an
774 "array of unspecified length".
775 stack.c Moved the language/frame mismatch check to
776 main.c:execute_command().
777 main.c The working language is recorded each time
778 execute_command() is executed. If working lang has
779 changed during its execution, then the new
780 language/type/range info is printed out for the user. If
781 the working language does not match the language of the
782 frame, a warning is issued.
784 Sat Jul 13 16:16:39 EDT 1991
786 eval.c Moved all the type-checking stuff for operators to
787 language.[ch] language.c. This is so we can keep language-specific
788 stuff (like for what type operators are defined) in
790 language.[ch] Added the function binop_type_check(), which checks to see
791 if its two (value) arguments are type-compatible with its
792 opcode argument. The opcode should represent an operation
793 involving an operator. Also added the macro function
794 unop_type_check, which calls binop_type_check with a
795 NULL second argument.
796 expprint.c Added Modula-2 operators to the op_print_tab, so info
797 expression.h break works correctly. Also added "op_string", which
798 returns the string corresponding to the (enum exp_opcode)
799 opcode that is its argument.
802 Sat Jul 13 18:26:18 EDT 1991
804 coffread.c Added code to record the type of function arguments with
805 each paricular function. Code is very similar to that
807 dbxread.c Moved add_param_to_type() to symtab.c
808 symtab.[ch] Added function add_param_to_type() from dbxread.c
810 *** NOTE: The above additions have not been tested.
812 Mon Jul 15 12:50:47 EDT 1991
814 langauge.[ch] Added the functions type_error and range_error, which work
815 like error() except if the type/range mode is set to
816 *_mode_warn, then they do not do a return_to_top_level(),
817 but merely print a warning.
818 Also changed [set|show]_[type|range]_command() to support
819 the new "warn" feature.
821 Thu Jul 18 17:50:54 EDT 1991
823 mipsread.c Added code to record the type of function arguments with
824 each particular function. Code is very similar to that
827 *** NOTE: The above additions have not been tested.
829 Fri Jul 19 11:19:10 EDT 1991
831 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
832 UMIN_OF_SIZE, which when given a size of a numeric type,
833 return the maximum and minimum value it can hold. UMAX...
834 and UMIN... return the result for unsigned types.
835 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
836 struct types. They call above macros.
837 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
838 avoid a name conlict with the above.
839 c-exp.y Added range checking on numeric constants in
840 parse_number() for completeness.
841 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
842 return 0 if working_lang is not language_c.
844 Thu Aug 8 14:17:22 EDT 1991
848 breakpoint.c Documentation strings of some commands changed to
849 eliminate the references to the C language where
852 Tue Aug 13 15:48:03 EDT 1991
854 m2-exp.y Added qualified identifiers to the grammar. The semantics
855 are slightly different from those of the GDB operator ::
857 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
858 type_exp, where type_exp is any valid type expression.
860 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
861 printcmd.c Modified ptype_command() so it actually parses the input
862 (necessary for type expressions with scope qualifiers).
863 Added the function ptype_eval() which expects an
864 expression composed of one OP_TYPE element.
865 *.[ch] Replaced all occurences of parse_c_expression with
867 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
869 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
871 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
873 Small fixes from Peter Schauer:
875 * infrun.c (child_attach): Lint.
876 * solib.c (find_solib): Handle shared libs version 2.
878 Small fixes from David Wood:
880 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
884 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
885 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
887 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
888 chars_per_line is at maximum (user typed `set width 0'). Fix
889 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
891 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
893 * coredep.c: include ptrace.h where necessary.
894 * mipsread.c(parse_lines): fix unsigned char problem that was
895 messing up line numbers on SGI's and possibly other MIPS based
897 * infrun.c (child_create_inferior): use better test to check
898 return val from setpgrp().
899 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
900 for sgi/irix support.
902 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
904 * mipsread.c (parse_symbol): Put non-static procedures
907 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
909 Patch together `text_start' and `text_end' for 29K port.
911 * exec.c (exec_command): If NEED_TEXT_START_END, define the
912 variables and set them based on the exec file.
913 * am29k-tdep.c: declare text_start.
914 * valops.c (call_function_by_hand): declare text_end.
916 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
917 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
918 because machines that do this will also have to know to
919 set NEED_TEXT_START_END. Besides, it was a redundant way to
921 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
922 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
925 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
927 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
929 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
930 Pass MUNCH_DEFINE to munch whenever we run it.
931 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
932 format string; use 0x%x instead.
933 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
934 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
935 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
936 * inflow.c: Handle `short' process group IDs.
937 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
938 and check for ptrace errors.
939 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
940 (coff_symfile_init): Initialize text_bfd_scnum.
941 (read_coff_symtab): Use it to find the text [and absolute?] sections.
942 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
943 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
944 Merge target arm case with other "easy" cases. Add target
945 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
946 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
948 * minimon.h, remote-adapt.c, remote-mm.c: Add.
949 * munch: Cope with RT/PC putting fns in data segment.
950 Restore ability to override `nm' by specifying MUNCH_NM.
951 * xconfig/rtbsd, xconfig/ultra3: New host systems.
952 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
953 and remote-adapt. Remove encapsulated coff #define's (the
954 support should go in BFD, and gdb shouldn't know or care).
955 * tconfig/a29k-kern: Same, but for remote kernel debugging.
956 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
957 * tm-29k.h: Update BADMAG (though it should go away).
958 Allow the register definitions to be overridden in another
959 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
960 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
961 DUMMY_SAVE_GR96, for handling kernel calling conventions
962 that use GR64+ rather than GR96+.
963 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
964 remote debugging of Ultra3 kernel. Includes tm-29k.h and
965 overrides various things.
967 * remote-mm.c (mm_attach, mm_wait): Handle attach like
968 child_attach does, making a clean stop in the newly attached
972 * coffread.c: Make coffread independent of any particular
973 variant of COFF. Avoid #include-ing any particular one except
974 internalcoff.h. BFD now passes key values for symbol reading
975 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
976 and the symbol masks and shifts); use them.
977 Remove obsolete end_of_text_addr.
979 * exec.c: Remove unused include files.
981 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
983 * Makefile.in (documentation targets): Pass $(M4).
984 Bugfix from eggert@twinsun.com (Paul Eggert).
986 * stack.c (down_silently_command): Check for stack existence.
988 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
990 * Makefile.in (VERSION): Update to 4.0.3.
992 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
994 * core.c (core_file_command): Print frame at coredump with
995 its level number, by calling print_stack_frame.
996 * frame.h: Add selected_frame_level, print_stack_frame.
997 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
998 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
999 Change print_sel_frame and print_selected_frame callers to
1002 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1003 * symfile.c (free_named_symtabs): Ditto.
1004 * main.c (main): wrap_here needs an arg.
1005 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1006 (solib_add): Avoid noise.
1007 (solib_create_inferior_hook): Lint.
1008 (sharedlibrary_command): Move dont_repeat to here.
1009 * utils.c (error): Call wrap_here to force buffered output.
1011 Small patches from Peter Schauer:
1013 * coffread.c (start_symtab): Free any existing line_vector before
1015 (read_coff_symtab): Ditto for type_vector.
1017 * source.c (lines_to_list): New variable, replacing function.
1018 (all uses): Use as variable.
1019 (_initialize_source): Add 'set listsize' and 'show listsize'.
1020 * utils.c (lines_to_list): Remove function.
1021 * stack.c (print_frame_info): Use as variable.
1022 * defs.h (lines_to_list): Remove declaration.
1024 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1026 * breakpoint.c (insert_breakpoints): Restore warning about
1027 the program might be running in another process, but only for
1028 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1029 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1031 * utils.c (error): if error_pre_print is set, print the string
1033 * main.c (main, print_gnu_advertisement, print_gdb_version):
1034 Reformat legalese so it always prints, but acts as an "I'm here"
1035 message while symbols are being read. If any errors occur,
1036 print a few newlines to set off the message and start it at the
1037 left margin. Remove mention of "help" command, and don't yak
1038 about symbol reading.
1039 (catch_errors): Error string is now printed first in case of
1041 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1042 suggest the "help" command.
1044 * Makefile.in (VERSION): Set to 4.0.2.
1046 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1048 * .gdbinit: Remove useless "rr" command. Set complaints
1049 to 1 for people debugging gdb.
1051 * breakpoint.c, remote-vx.c: Reword strings printed by
1052 catch_errors callers.
1054 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1056 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1057 (Fix from kenc@viewlogic.com.)
1059 Fix some infrastructure to be able to cope with host and target
1060 machines with different sized basic types (ints, ptrs, etc).
1061 (Idea from pierre@la.tce.com (Pierre Willard).)
1063 * values.c (value_from_longest): Rename from value_from_long.
1064 Handle pointer types as well as integers, so that targets with
1065 different pointer sizes from the host can be accomodated.
1066 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1067 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1068 uses of value_from_long to value_from_longest.
1069 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1070 the correct pointer type to value_from_long{est}.
1072 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1074 * remote-vx.c: Remove obsolete code for calling functions via
1075 vxworks kludge interface (it referenced value_from_long).
1077 * valops.c (value_string): Find malloc with lookup_misc_func, not
1080 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1082 Make writing to files work properly. (Fixes to BFD are also needed.)
1084 * core.c (core_open): Open file ourselves, read or r/w, depending on
1085 write_files. Use bfd_fdopenr.
1086 * gdbcore.h (write_files): New variable.
1087 * exec.c (write_files): Define variable, add set&show for it.
1088 (exec_file_command): Use write_files to open for read or r/write.
1090 Make shared library reading happen automatically. These changes
1091 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1093 * inferior.h (stop_soon_quietly): Add to exported variables.
1094 * infrun.c (child_create_inferior): call solib hook, if defined.
1095 (child_attach): call solib hook, if defined.
1096 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1097 (find_solib): Use lookup_misc_func rather than hand-rolled.
1098 (symbol_add_stub): New stub for catch_errors.
1099 (solib_add): Avoid output if !from_tty. Catch errors rather
1100 than just calling symbol_file_add and bombing.
1101 (solib_create_inferior_hook): Interface with the target process
1102 to let it read and alloc shared libs, then figure out what it did.
1104 * core.c (validate_files): Fix typo, soften warning.
1105 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1107 * utils.c (fputs_demangled): Avoid duplicate printing if
1108 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1110 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1111 (Fix from pierre@la.tce.com (Pierre Willard).)
1113 * main.c (catch_errors): Change argument to a char * from an int,
1114 since a char * can point to a struct full of glop, but an int
1115 is not guaranteed to be able to hold a pointer.
1116 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1117 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1118 * core.c (core_open, solib_add_stub): Adapt.
1119 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1121 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1123 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1124 by adding .NOEXPORT target.
1126 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1130 * Makefile.in (VERSION): Roll to 4.0.
1131 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1133 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1135 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1138 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1141 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1143 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1144 reflect above name change
1146 * WHATS.NEW: correct pointer to refcard.
1148 * doc/gdb.texinfo: update New Features, Installing
1150 * doc/gdbint.texinfo: add short description of configure +template
1152 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1154 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1156 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1158 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1159 tar file, add dependencies for referenced doc files.
1161 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1163 * coffread.c, symfile.c, stack.c: saberized.
1165 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1167 * doc/refcard.tex: permuted Essential Commands sec
1169 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1171 set/show symbol-reloading
1172 default set complaints 0
1174 RET-repeat disabled after prompted long displays
1175 processID (attach) interpretation of 2nd GDB cmdline arg
1177 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1179 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1180 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1181 breakpoint.c, main.c: lint.
1183 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1185 Install new configuration scheme for GDB and friends.
1187 * config.sub: Translate ordinary names to three-part names.
1188 * configure: Use three-part names internally.
1189 * configure.in: Translate three-part names to filenames.
1191 * README, WHATS.NEW: Update for gdb-4.0.
1192 * Makefile.in: Roll VERSION to 3.99.
1194 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1196 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1197 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1198 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1199 to single structures rather than arrays; when passing
1200 their address, use &. This avoids trouble with bdead compilers.
1201 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1202 instead. This avoids portability headaches.
1203 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1205 * source.c (open_source_file): Avoid ANSI const bdeath by
1206 skipping declaration and then casting result value.
1207 * tm-hp300bsd.h: Clarify comment.
1208 * utils.c (strstr): Result is const char *; ANSI bdeath.
1209 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1210 since system include file defines it differently from "defs.h",
1211 though the two are equivalent for our purposes.
1212 * tconfig/hp300bsd: Add m68k-tdep.o.
1214 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1216 * tconfig/sun*4: Remove warnings about system assembler.
1218 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1220 * mcheck.c: Avoid warning about undeclared abort fn.
1221 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1222 it causes recursive calls to error() when used in cleanups.
1223 To do so requires that we make it a function, so we do.
1224 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1225 * utils.c (do_cleanups): Remove the current cleanup from the
1226 chain *before* calling it, in case error() is called from it.
1227 The result won't be pretty, but won't be an infinite loop either.
1229 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1231 * dbxread.c (read_struct_type): Grok anon structs for C++.
1232 (vb_name, vptr_name): Null terminate these strings.
1234 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1236 Minor bug fixes from BSD Net2 gdb:
1238 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1239 returns 0, there is no previous frame.
1240 * breakpoint.c (commands_command): If !from_tty, don't call
1241 input_from_terminal_p().
1242 * dbxread.c (record_misc_function): Speed up slightly.
1243 (compare_psymbols): Ditto.
1244 * infcmd.c (do_registers_info): Take a second argument to
1245 determine whether to print float registers. "info registers"
1246 does not do so anymore. "info all-registers" does, now.
1247 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1249 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1250 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1254 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1255 executing_breakpoint_commands if we are interrupted by error.
1256 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1257 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1258 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1259 catch_errors() so we can setup the frame regardless of whether
1260 the shared libs work.
1261 * ieee-float.c (double_to_ieee_extended): Get exponent from
1262 right place in little-endian systems. From John Carey.
1264 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1266 * main.c: Remove unused terminating_signals and catch_termination().
1267 (long_options): Terminate with a zero element.
1268 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1269 (gdb_readline): Make call-compatible with readline.
1270 (init_signals): Improve comments re vfork vs. signal.
1272 * utils.c (prompt_for_continue): Use new gdb_readline().
1273 If we prompt for continuation, we don't let CR repeat the previous
1274 command, once we get back to a prompt. It's too easy to keep
1275 hitting CR, expecting "--more--" prompts, and have some long
1276 command start repeating on you.
1278 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1280 * blockframe.c (frameless_look_for_prologue): Speed up by
1281 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1282 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1283 Define two variants, one faster.
1284 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1285 and return zero, rather than giving an error.
1286 (setup_arbitrary_frame): Initialize the PC in the new frame.
1287 (skip_prologue): Add a second arg saying whether we're just
1288 checking for a frameless function or not.
1290 * core.c (core_open, core_close, core_xfer_memory): Move
1291 section table pointers and bfd* into the target_ops.
1292 (core_open): Allow errors in shared lib reading, etc.
1293 (core_files_info): Describe shared library sections.
1295 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1296 exec_files_info, set_section_command): Move section table
1297 pointers and bfd* into the target_ops.
1298 (add_to_section_table): Add BFD to section table.
1300 * target.c (target_xfer_memory, target_info): Pass target to
1301 xfer_memory and target_info functions.
1304 * gdbcore.h: Move struct section_table.
1305 * target.h: New home of struct section_table.
1307 * solib.c (solib_add): New argument is the target_ops whose
1308 section list is to be added to, if any. Reallocate the
1309 sections in that target to add any that come from shared libs.
1310 (throughout) so_sections renamed to sections.
1311 (solib_xfer_memory): Deleted.
1312 * tm-sunos.h (SOLIB_ADD): Add target argument.
1313 (SOLIB_XFER_MEMORY): Delete.
1315 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1316 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1317 from target_ops. It's the same on all targets. Add two section
1318 pointers to target_ops.
1320 * stack.c (find_relative_frame): Dump ancient algorithm for
1321 "down", just use handy "next" pointers.
1322 (frame_command): Don't error if there is no stack; let user
1325 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1326 modifies static state in the parent process; new_tty itself
1327 runs in the child and modifies the child's file descriptors
1328 to match the saved static state.
1329 * infrun.c (child_create_inferior): Call new_tty_prefork,
1332 * infptrace.c (child_xfer_memory): Add ignored target arg.
1333 * remote-eb.c (eb_xfer_inferior_memory): ''
1334 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1335 * remote-vx.c (vx_xfer_memory): ''
1336 * remote.c (remote_xfer_memory): ''. Rename from
1337 remote_xfer_inferior_memory.
1339 * main.c (main): Only try to attach "corefile" argument if
1340 it starts with a digit.
1342 * symfile.c (symbol_reloading): New "set/show" variable.
1343 (symbol_file_add): Shorten message about symbol reading.
1344 (add_symbol_file_command): Merge with add_syms_addr_command,
1345 since this should work on all targets now.
1346 (stop_whining): Default to zero, to shut up complaints
1347 about bad symbol tables on many systems.
1348 (free_named_symtabs): Just exit unless symbol_reloading.
1350 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1351 and add comment explaining shared library screw.
1353 * source.c: #if defined => #ifdef.
1355 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1357 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1359 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1361 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1362 (doc/Makefile knows how to make one for local config)
1364 * Makefile.in: use doc/Makefile for doc targets
1366 * doc/Makefile: GDB documentation now has its own Makefile
1367 doc/refcard.tex: renamed from "gdbrc.tex"
1368 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1369 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1372 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1374 * values.c (baseclass_addr): When reading target memory, use the
1375 length of the basetype, not the upper type. We've only malloc'd
1376 enough space for the basetype, leading to errors in free().
1378 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1379 ends up as a function specially, since we know the actual type of
1380 the pointed-to address. This (somewhat) fixes display of
1381 expressions that include misc_function_vector names. Try `cond 1
1382 !strcmp("a","b")' then `i b'.
1384 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1385 The child can be proceeded from inside wait_for_inferior in
1386 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1387 getting skipped in that case.
1389 * expprint.c (print_subexp): Use filtered output, since the
1390 subroutines we call use it, otherwise the output is horribly
1391 mangled, since output of wrappable stuff comes out late.
1393 * Makefile.in: Bump VERSION to 3.98.1
1395 * infrun.c (child_create_process): Use execlp to find the
1396 shell to exec our target program. This requires some fiddling
1397 with `environ' since there is no execlpe().
1399 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1401 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1402 Minor rearrangement of refcard permits two new make targets--
1403 gdbrc.dvi DVI output for refcard, using CM fonts
1404 gdbrc.ps PostScript refcard, using PS fonts
1406 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1410 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1411 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1413 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1415 * doc/gdb.texinfo: last changes for release.
1416 Minor typo and formatting fixes; incorporated most fixes remaining from
1417 filed mail commenting on earlier drafts.
1419 Added warnings: pipes don't work in run command;
1420 conditions are converse of assertions;
1421 step over fn without debug info goes to next fn;
1422 vars may have "wrong" values near fn entrance, exit
1424 Added example from Kingston on printing repeated nonadjacent values
1426 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1427 shell mode for signals
1429 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1430 doesn't sound so much like its parent "Stopping and Continuing"; also
1431 moved entries on continue to top of section, so they don't get lost.
1433 Improved installation directions in appendix, added manual formatting
1436 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1438 * configure.in: Remove xm.h and tm.h even if we aren't linking
1439 new ones, so "./configure sun4; ./configure none" does the right
1440 thing. Assume that alldeps.mak and depend are already built in
1441 srcdir, and avoid running "make" (particularly "make depend",
1442 which involves "gcc") from inside configure. Build Makefile
1443 directly rather than building Makefile.conf first.
1444 * configure: Regenerate with above changes.
1445 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1446 to 3.98. Revise gdb.tar.Z procedure to produce a file
1447 called gdb-$(VERSION).tar.Z but which unpacks into a
1448 directory called "gdb". Move non-source files out of
1449 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1450 (depend): Don't try to do "gcc expread.y".
1451 (expread.o): Update dependencies by hand.
1453 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1456 Fixed a variety of small typos that prevented info from formatting
1457 cleanly; altered too-long heading for GPL Appendix, as discussed
1458 w/RMS; Changed date on cover to July 91.
1460 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1463 (1) Applied some fixes due to comments from Larry Breed (easier ones
1464 through chapsec 5.2)
1465 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1466 it's broken in latest texinfo
1467 (3) Introduced *some* use of [] for optional arguments, where
1468 explanation is not simpler by listing cmd w arg and cmd w/out arg
1469 separately. Still not using @deffn.
1470 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1471 couple of headings are too long. Need patches to texinfo or revision
1474 * Partial update to README (which still needs work for this
1475 release!): (1) use of configure corrected for new script,
1476 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1478 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1480 * symtab.c (lookup_symbol): Don't complain right off about
1481 no debug symbols; use the misc function vector first.
1482 (list_symbols): Use misc function vector to find symbols
1483 that don't have debug info, and print them.
1484 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1485 PC range doesn't match symtab PC range, as it does on the
1486 MIPS because our symtab reading isn't perfect.
1488 * dbxread.c (dbx_symfile_read): Make warning about
1489 "no debug symbols" slightly nicer.
1491 * source.c (select_source_symtab): If "main" symbol exists,
1492 but decode_line_spec can't find line info, don't just return
1493 a zero; try other source symtabs or give an error.
1495 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1496 their low addresses first, then rip through fixing high addrs.
1498 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1499 <runene@ifi.uio.no>.
1500 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1502 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1504 * Minor, mostly mechanical, cleanup of doc subdir for clean
1505 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1506 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1508 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
1510 Mostly MIPS and general symbol-reading fixups.
1512 * doc/gdbint.texinfo: Add documentation on symbol-reading
1515 * mipsread.c: Remove kludges around #include "ecoff.h".
1516 Remove redefinitions of a_magic, etc, no longer used.
1517 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
1518 Fix global overview comments to match symfile.c protocol.
1519 (mipscoff_new_init): Eliminate cur_hdr if we have one.
1520 (mipscoff_symfile_read): Eliminate unused code. Avoid
1521 sorting all the symtabs, when all we have read here is psymtabs.
1522 The symtabs are sorted as they are created anyway. Tell
1523 condense_misc_bunches whether we're mainline.
1524 (psymtab_to_symtab_1): Pass filename when recursing, to make
1525 stack trace more informative.
1526 (parse_partial_symbols): Assume cur_hdr as argument.
1527 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
1528 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
1529 the TYPE_NAME of char *, since that's done in symfile.c.
1530 (free_numargs, parse_symbol, add_symbol, add_block,
1531 shrink_linetable): Declare these fns void.
1532 (upgrade_type): Convert tree of if's to switch. Clean up
1533 bogus "off == 0" handling with a complaint. Avoid setting
1534 field bitpos and bitsize of array with lower and upper bounds.
1535 Check specified bitsize of elements against their actual type's
1536 bitsize, and complain if different. Complain about unknown
1538 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
1539 (psymtab_to_symtab_1): Print names of subsidiary files that
1540 are being read in. FIXME, we read far too many files. This code
1541 is not the problem, the problem is in parse_fdr where the psymtabs
1543 (cross_ref): Result should indicate that we used one aux entry
1544 normally, or two if we encountered a "next" entry. This used
1545 to leave the caller pointing at the wrong aux entry.
1546 (add_symbol): If overflowed cur_block, reallocate it larger,
1547 chase all pointers to it, and complain(), rather than clobber memory.
1548 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
1549 (new_field): Only allocate one field initially, not two.
1550 Pull ++ out of macro argument. Simplify.
1551 (_initialize_mipsread): Avoid initialization of importd
1552 global_psymbols and static_psymbols.
1554 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
1555 to properly set pst->symtab; avoid searching for it.
1556 (symfile_fns): Improve comments, add a FIXME.
1557 * dbxread.c: Update comments to reflect symfile protocol.
1558 (read_ofile_symtab, end_symtab): Return the symtab.
1559 (psymtab_to_symtab_1): Set pst->symtab.
1561 * coffread.c (coff_symfile_read): tell condense_misc_bunches
1562 whether we're mainline.
1564 * symfile.h (sym_fns): Remove unused sym_discard member.
1565 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
1567 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
1568 the environment variable is not.
1569 * infcmd.c (finish_command): Use filtered printfs.
1570 * cplus-dem.c: Add struct tags to a few unnamed structs.
1571 * valops.c (value_coerce_array): Improve comments.
1572 * valprint.c (type_print_varspec_suffix): Print array size only
1573 if greater than zero.
1574 * m88k-tdep.c: Shift some lines left by one space, that had
1575 apparently been trashed at some point.
1576 * TODO: More things to do, a few got done.
1578 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1580 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
1581 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
1583 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
1584 * expread.y, findvar.c, symmisc.c: Ditto.
1585 * printcmd.c (address_info): Update printed forms of LOC_
1586 symbols. Elim LOC_EXTERNAL.
1587 (print_frame_args): Keep track of param stack offsets before
1588 re-looking up to find the local register param is kept in.
1590 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
1591 Further integration of mipsread into gdb. Eliminate unused
1592 routines, duplicate declarations. Handle static symbols in
1593 psymtabs as well as external symbols. When reading symtabs,
1594 insert symbols into the correct block (global, static, or a local
1596 (read_mips_symtab, parse_partial_symbols): Don't pass useless
1598 (mipscoff_symfile_read): Don't call select_source_symtab.
1599 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
1600 rather than SYMBOL_VALUE.
1601 (parse_external): Comment clobbering of top_stack.
1602 (parse_partial_symbols): Update comments. Allocate and parse
1603 static symbols as well as external symbols. FIXME, enum values
1604 are not handled in this pass, but should be. Inline new_psymbol.
1605 Use SYMBOL_VALUE_ADDRESS.
1606 (psymtab_to_symtab_1): Read symbols into global static block
1607 by default (until enter some function's local block context).
1608 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
1609 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
1611 * source.c (select_source_symtab): Select a source symtab
1612 from either the symtabs or, failing that, the psymtabs.
1613 (list_command): Update error message.
1614 (forward_search_command, reverse_search_command): Use getc, not
1615 fgetc, for speed. FIXME, add comment about buffers that die if
1616 overrun by long line.
1618 * values.c (unpack_field_as_long, modify_field): Avoid shifting
1619 by an entire word, which is not portable, if we have a 32-bit
1620 field. (Code in dbxread.c already turns such bitfields, if
1621 aligned, into ordinary ints, but fixing this will help for other
1622 symbol formats and for future changes.)
1623 * core.c (core_open): Handle ANSI const brain death.
1624 * utils.c (vprintf): Fix varargs typo.
1626 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1628 * findvar.c (find_var_value): Handle &function better.
1629 * TODO: Document work needed on &fn and &array.
1630 * printcmd.c (print_address_symbolic): New arg is the prefix
1631 to print if a name is printed.
1632 (print_address_demangle): Honor "set print address" now.
1633 Use new arg above to improve spacing of output.
1634 * valprint.c (val_print): When printing function pointers,
1635 print symbolic form too.
1636 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
1638 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1640 * core.c (memory_error): Reword error msg to mislead less.
1642 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
1644 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
1645 parse_partial_symbols): Use newer BFD internals (external_filehdr
1646 and external_aouthdr), byte-swap the fields that we care about
1647 before using them, and make the file header data local to
1648 read_the_mips_symtab rather than global.
1650 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
1652 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
1653 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
1655 * main.c (command_line_input): Flush stdout and stderr
1656 before every call to readline. This reportedly fixes a bug
1657 that comes up in Sys V running emacs-gdb and/or xxgdb,
1658 when stdin/out are pipes or sockets.
1660 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1662 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
1663 Avoid declaring Makefile dependencies, because GNU Make stupidly
1664 tries to update it if we do.
1666 * coffread.c: Revise for minor changes to bfd internal coff
1669 * configure: If -template= is given a relative path, make it
1670 absolute before recurring in subdirectories.
1672 * configure, configure.in, Makefile.in: Install "configure" script
1673 as replacement for config.gdb.
1674 * config.gdb, Makefile.dist, Makefile.sdir: Remove
1675 * README: Update for configure, mostly. FIXME.
1677 * Add dec3100 as equivalent to littlemips. Indicate in all host &
1678 target config files that they are for the host. When the lines
1679 get copied into the Makefile, this makes it more obvious what's
1682 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1684 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
1685 tabs, which end up in the disassembler output inadvertently.
1687 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1689 Make it compile cleanly in an ANSI GCC2 environment.
1691 * blockframe.c: <stdio.h>
1692 * cplus-dem.c: free takes a void *, ifdef __STDC__
1693 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
1695 * defs.h (alloca): Avoid doing anything if alloca already def'd.
1696 * stddef.h, stdlib.h: Remove these files.
1697 * symtab.c: Avoid declaring qsort, close.
1698 * symfile.c: Avoid declaring close.
1699 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
1700 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
1702 Assorted other changes.
1703 * dbxread.c: include "libaout.h", not "liba.out.h".
1704 * printcmd.c (print_frame_args): Set recurse properly for
1705 indentation of struct and array parameters.
1706 * valops.c (value_cast): Allow cast to void.
1707 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
1708 single_step() in a target-independent fashion.
1709 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
1710 set up to be ready to continue. This makes us target independent.
1711 * infptrace.c (child_resume): Remove call to single_step; now
1712 can single step a SPARC target of any kind.
1714 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1716 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
1717 docn into separate sections---basically chapters, plus two loose
1718 pieces that can be configured to go in different places. This
1719 allows GNU m4 to preprocess the manual without coredumping.
1721 * Makefile.dist: tell TeX where to find texinfo.
1723 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1725 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
1726 the new target "rdl-apps.texinfo" which captures the Makefile
1727 variable that records where to find the Readline libraries.
1729 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
1731 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
1732 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
1733 * defs.h (const, volatile): Only define if not already defined.
1734 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
1736 * README: Update for release 3.95.
1737 * config.gdb: Don't create readline dir in subdir builds.
1738 * main.c: Include with "..." form for non-system include files,
1739 so "gcc -MM" for "make depend" works.
1740 Include readline files with "...h" rather than <readline/...h>.
1741 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
1743 * coffread.c: Undo minor damage done by Rich Pixley. Use
1744 different internal and external representations of COFF
1745 data structures. Use new BFD routines for swapping them in and
1747 * symfile.c (free_named_symtabs): Avoid freeing file names that
1748 are null or empty. Old i960 tools seem to produce files that
1749 claim to have empty names, causing each successive file read
1750 to blow away the previous one.
1751 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
1752 Move deferred_stores to top of file, but don't separate its
1753 #define's from its variable. Add commentary.
1754 * Makefile.dist: Fix Rich damage; undo "configure" changes in
1755 favor of keeping the (working) config.gdb. Move readline
1758 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
1760 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
1762 * infptrace.c (fetch_registers): no result, since now void.
1763 * tconfig/news: target depends on m68k-tdep too.
1765 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1767 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
1770 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
1771 applied various small fixes due to or inspired by RMS comments
1773 * doc/gdb.texinfo: finished using all RMS comments, save those for
1774 appendices on readline and cmd history (which are in other source
1777 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1779 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
1780 chapter 9; (2) documented 'break' command's menu mode for
1781 overloaded names, in response to hgs problem report C++ p-31
1783 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1785 * doc/gdb.texinfo: (1) better introductory example; (2) more
1786 consistent use of @code, @samp, @file, @kbd throughout; small
1787 cleanups to first three nodes; (3) new "Contributors" node;
1788 (4) Appendix, Renamed Commands; (5) divert specialized startup
1789 instructions to "Targets" chapter for generic manuals, while
1790 leaving them up front for manuals specific to specialized
1791 environments; (6) apply fixes from RMS comments through chapter 4.
1793 * pretex.m4: modify explanatory text slightly (and redefine
1794 "regexp") to keep GNU m4 from complaining. (It still crashes
1795 later, but one step at a time...)
1797 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
1799 * readline/readline.c (update_line): Avoid dereferencing a pointer
1800 before comparing it to its bounds. Saber caught this.
1801 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
1802 and only set PC if tgetstr returned non-null. Saber caught this.
1804 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1806 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
1807 stuff for config manual) here where it counts; updated
1808 to use new subdir structure (gdb/doc/).
1810 * Makefile: generated from above via
1814 * gdbint.texinfo: added instructions on generating gdb.info* files
1815 locally for release. These are ordinary info
1816 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
1817 Makefile)---but due to use of texinfo 2, can't count on makeinfo
1818 to generate these, so we distribute them already formatted.
1820 * gdb.texinfo: included full Info node and menu crud (as generated
1821 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
1823 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
1824 put in comments-for-future gdb.info target (one day makeinfo will
1827 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1829 * gdb.texinfo: Updated to include new or old undocumented
1830 commands, at least the following (perhaps some others I forgot to
1831 record): info f, info float, info path, info program, info s, info
1832 set, info source, info terminal, info types, info user, set/show
1834 Also covered all recent GDB command renames for v4.
1836 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1838 * mipsread.c: Rather than keeping count of how many symtabs
1839 and psymtabs we have, for sorting purposes, count them when
1840 we need to sort. This fixes bug in rereading of symbol tables.
1842 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1844 * infcmd.c: renamed "info path" to "show paths"
1845 * gdbrc.tex: documented above.
1847 Wed May 8 04:51:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1849 * remote.c: Fix comments.
1850 * utils.c (error): Force out any pending wrap output.
1852 Sat May 4 11:11:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1854 * Makefile.dist: Roll VERSION to 3.95.
1855 Fix up "saber_gdb" to work again.
1856 * saber.suppress: Update.
1858 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
1859 symtab.h, target.c, target.h: Lint.
1860 * core.c: setup and select frame after reading shared libs,
1861 else reading shared libs will clobber them. Lint.
1862 * utils.c (error): Force out any buffered wrap text.
1864 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1866 * remote.c: Remove decls of memory_insert_breakpoint
1867 and memory_remove_breakpoint, no longer used. (Suggestion of
1870 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
1871 to make it easier to interface to "configure"'d libraries.
1873 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
1875 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
1876 aliases for set/show print.
1878 Thu May 2 11:22:02 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

1918 * {x,t}config/m88k ({X,T}DEPFILES): Add missing files.
1920 * mtrace.c: Don't typedef things like size_t, just #define them.

1924 * symtab.h (struct symtab): Include EXTRA_SYMTAB_INFO.
1925 tm-88k.h: Define EXTRA_SYMTAB_INFO.

1928 dc_dcontext_t not int.
1930 * coffread.c [TDESC]: Use system include files not <intel-coff.h>.
1932 * coffread.c [TDESC]: Move setting of debug_info from
1933 coff_symfile_read to find_linenos and make it work with BFD.
1935 * cplus-dem.c [__STDC__]: Make x{m,re}alloc return void*.
1937 * signame.c: Cast const char* to char* when assigning to sys_siglist.
1939 * utils.c (strsave): Make arg const char* not char*.
1941 * infrun.c (wait_for_inferior) [SHIFT_INSN_REGS]: Use
1942 bpstat_explains_signal (stop_bpstat) not stop_breakpoint.

1960 Thu May 2 17:53:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1962 Mips bringup and general cleanup
1964 * cplus-dem.c: Move CPLUS_MARKER define to after defs.h.
1965 * infptrace.c (PT_WRITE_D, PT_READ_D): Use correct values.
1966 (This still doesn't seem to make MIPS bkpts work.)
1967 * mipsread.c: Remove dup "Reading symbol data..." msg.
1968 (symbol_file_command, add_file_command): Remove, obsol.
1969 * printcmd.c (ptype_command): Say "an enum" rather than "a enum".
1970 Wrap output appropriately.
1971 * stack.c (locals_info, catch_info, args_info): Check
1972 selected_frame rather than target_has_stack or coredumping.
1973 * valprint.c (type_print_varspec_suffix): Wrap "ptype" output of
1974 enums appropriately.
1976 Wed May 1 14:10:22 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

2449 * dbxread.c (end_symtab): Ditto.
2450 * expread.y (block): Ditto.
2451 * mipsread.c (throughout): Ditto.
2452 * symmisc.c (free_named_symtabs): Ditto.
2454 * symtab.c (list_symbols): Process the first symbol of the
2455 static psymbols list.
2456 (types_info): Restore this function from its untimely #if 0.
2457 It's not perfect, but it is better than nothing.
2458 (_initialize_symtab): Restore "info types".
2460 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2462 * m68k-stub.c: Remote stub for 680x0's, created from
2463 rem-m68k.shar (which is removed).
2464 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
2465 Remove RCS log stuff now that we use CVS and it blows our diffs.
2467 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2469 * symmisc.c (free_named_symtab): Make it work, in its current
2470 kludgy fashion. Change result to indicate if we blew away bkpts.
2471 * dbxread.c (end_symtab): Accumulate result from
2472 free_named_symtab and print warning if we blew user's state.
2473 * symfile.h: free_named_symtab now returns an int.
2475 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
2477 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
2478 is the first symbol read, even if not mainline.
2479 (dbx_psymtab_to_symtab): symfile might be zero, cope.
2480 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
2481 (set_section_command): New command ("section xxx yyy" -- should
2482 be renamed to "set section xxx yyy" FIXME) which sets the
2483 base address of a section of the exec file, overriding the
2484 virtual address that BFD reports.
2486 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2488 * exec.c: Add add_syms_addr_command to exec_ops, so you can
2489 load symbols at any address while examining an exec file.
2491 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2493 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
2494 for printing the float info is host-dependent, not
2495 target-dependent. FIXME.
2496 * i386-pinsn.c: Move #includes to top, remove useless ones.
2497 * i386-tdep.c: Don't bother including <.../reg.h> since we
2498 don't use it (and it doesn't exist on host systems).
2500 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
2501 Convert negative numbers properly.
2502 (ieee_test): Make numbers really random; fix format arg.
2504 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
2505 * core.c (core_detach): Unpush core_ops, which might not be on
2506 top. We used to just pop the top, which broke things. Don't
2507 need dont_repeat() any more.
2508 (core_file_command): Psst! Don't repeat it.
2509 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
2510 * expprint.c (print_subexp): Avoid switch fallthru on
2511 BINOP_ASSIGN_MODIFY, so we can print += and such.
2512 * frame.h: Fix typo.
2513 * inflow.c (kill_command): After killing inferior, print our
2514 current frame in the core file, if we have one.
2515 (generic_mourn_inferior): When inferior dies, either select
2516 the current frame (in the new target, e.g. core file), or
2517 set both the current and selected frames to NULL.
2519 Changes from Peter Schauer.
2521 * infptrace.c: Avoid <sys/ptrace.h> on USG.
2523 * Make all file names fit in 14 characters (sigh and damn!):
2524 mv hp300hpux-xdep.c hp300ux-xdep.c
2525 mv symmetry-xdep.c symm-xdep.c
2526 mv symmetry-tdep.c symm-tdep.c
2527 mv convex-opcode.h convx-opcode.h
2528 mv tm-vxworks960.h tm-vx960.h
2529 mv tm-vxworks68.h tm-vx68.h
2530 mv Makefile.srcdir Makefile.sdir
2531 mv gdb-int.texinfo gdbint.texinfo
2532 mv remote-sa.m68k.shar rem-m68k.shar
2533 mv remote-multi.shar rem-multi.shar
2534 * Makefile.dist, README, config.gdb, convex-pinsn.c,
2535 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
2536 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
2539 * command.c (user_info_1, user_info): New command for listing
2540 the user-defined commands.
2542 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2544 * dbxread.c (really_free_pendings): Clear file_symbols
2545 and global_symbols after freeing them; otherwise, running
2546 this function twice (if it appears twice on the cleanup
2547 chain), we try to free things twice.
2549 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
2550 based on text_addr (the address of text in core), not on addr (the
2551 offset between text in the .o file and in core). This change
2552 is from Peter Schauer.
2554 * main.c: Define ALL_CLEANUPS as a cast of zero.
2555 (return_to_top_level): Use it.
2556 (main): Do all cleanups after each command run as part
2557 of the gdb startup sequence. Also do all cleanups before
2558 entering the command loop, and every time we exit the command
2559 loop and reenter. Before, the cleanups from the startup sequence
2560 were being left undone until the first error!
2561 (command_loop): Rename do_nothing cleanup to command_loop_marker
2562 so we can see it easily when examining the cleanup chain.
2563 (init_signals): Add another do_nothing for signal handling.
2564 (quit_command): Only try to kill target if it has execution.
2565 Problems in the target stack got us into a state where
2566 inferior_pid was nonzero but none of the targets had execution.
2567 In this state you couldn't exit gdb.
2569 * dbxread.c: Two changes from Peter Schauer.
2570 (echo_command): Fflush output after an echo command.
2571 (show_history): Pass all args to cmd_show_list.
2573 * utils.c (init_malloc): Call mtrace to turn on tracing
2574 if the environment variable MALLOC_TRACE is set to a file name.
2575 * mtrace.c: Add source file which provides a log of every malloc,
2576 free, and realloc to a trace file.
2577 * mtrace.awk: Add source file which analyzes the trace file.
2578 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
2579 (VERSION): Roll to 3.94.3.
2581 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
2582 (check_duplicates): Don't bother with watchpoints.
2583 (set_raw_breakpoint): Comment about danger of this routine.
2584 (watch_command): Parse and eval all args before calling
2587 * solib.c (find_solib): Avoid error in referencing memory to
2588 see if any more shared libraries have been added. This is
2589 particularly useful if the target has terminated. Bug reported
2592 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
2593 in bringing up 3.94.2 on the Sun-3.
2595 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
2596 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
2597 expression (in scope) before reenabling watchpoint.
2598 * signame.c (init_sigs): Add missing declaration of i, fix
2599 sys_siglist declaration.
2600 * source.c (list_command): Fixed range computation to use
2602 * stack.c (backtrace_command): Do not allow command if target has
2603 no stack, print informative error message.
2604 * target.c (target_command): Do not write into command line
2605 because this fails if the target command is used in a user defined
2606 command. [This change was enhanced by gnu to support any-
2607 unique-prefix matching on target names.]
2608 * valops.c (value_struct_elt): Avoid infinite loop on an
2609 erroneous attempt to print the member of function (try p main.p).
2611 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2613 * expread.y (name_no_typename): Avoid reduce/reduce errors
2614 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
2615 Since the GDB parser really doesn't use name_no_typename in a
2616 name-only context, the parser can't tell the diff between
2617 names and numbers here. Avoid allowing a name_no_typename
2618 to be a NAME_OR_*INT to resolve the conflict.
2620 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2622 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
2624 * valprint.c (val_print_fields): bitfield printing didn't handle
2625 byte order. Indirect through a few more fns to cope.
2627 * values.c (modify_field): also cope with byte order.
2629 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2631 Cleanup for release 3.94.2:
2633 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
2634 include files. Roll version to 3.94.2.
2636 * coffread.c (init_stringtab): Read length into unsigned char
2637 array before swapping; don't assume 32-bit longs.
2639 * target.c (target_info): Don't bother with get_sym_file, just use
2640 the symfile global variable.
2641 * symtab.h, symfile.c (get_sym_file): Delete it.
2643 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
2644 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
2645 (read_type): Replace one more error() with complain().
2647 * mipsread.c (parse_partial_symbols): Replace printf with complain.
2649 * i960-tdep.c: Fix copyright attribution.
2651 * config.gdb: Quote all backquotes in doublequotes. You can
2652 quote me on that. BSD 4.4 shell found this one.
2654 * infptrace.c (throughout): The third argument to ptrace is an
2657 * infrun.c (wait_for_inferior): When program has terminated, we
2658 have to call target_terminal_ours before we pop that target off
2659 the stack (e.g. before a call to target_kill or
2660 target_mourn_inferior). This fixes problem where a program
2661 terminates, then GDB stops for (tty output) and you have to type
2662 "fg" to the shell to resume it. FIXME: This code for what to
2663 do after termination really should be in normal_stop instead.
2665 * gdbcore.h (read_memory_check): Change declaration; it changed
2668 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
2669 4.4 prereleases, this avoids a bug in their sgtty compatability
2671 * remote.c: Use terminal.h rather than hand-rolling the same.
2673 * signame.c, signame.h (psignal): Arg is unsigned, not int.
2674 * utils.c (strsave, strstr): Fix arg types.
2675 * valprint.c (val_print): lint
2677 MIPS symbol table support from Per Bothner:
2679 * symfile.c (symtab_fns): Remove initializer table that needs to
2680 be hacked for each new symbol file format supported.
2681 (add_symtab_fns): New function, chains symbol table
2682 handlers into the global list.
2683 (symfile_init): Search this list.
2684 * symfile.h: Add next pointer, declare add_symtab_fns.
2685 * coffread.c (_initialize_coffread): Call add_symtab_fns.
2686 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
2688 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
2689 symbol *). Thus, we no longer need the hack to trash
2690 pst->filename. Good, since that hack confused code in symfile.c!
2692 (reorder_symtabs, destroy_all_symtabs): Removed static
2693 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
2694 Instead, the latter now uses a temporary array (stack-allocated
2695 from an obstack, and then freed).
2697 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
2698 haven't been set in the outermost stBlock of a procedure. This was
2699 a problem with f77 binaries on Ultrix 4.?.
2701 (new_symtab, new_symbol, new_type): Continue changing code to use
2702 obstacks more and otherwise conform to dbxread internal style.
2703 Made the free_code of symtabs be free_linetable (as in dbxread)
2704 instead of free_contents. This implies memory leaks when reading
2705 a new symbol table, until the conversion is finished. Did change
2706 (struct symbol) and (struct type) to be allocated on the
2707 symbol_obstack. Blocks and blockvectors are among the things
2710 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
2711 tested much, but it solved one problem (reported by Meissner), and
2712 cleans up some other things. The problem happened when an
2713 included file contains actual code (functions) and not just
2714 definitions. The mips coff is a little inconvenient there, since
2715 it may cause a procedure to be mapped to the wrong psymtab.
2717 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
2718 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
2719 this will need work for the new core paradigm.
2721 Opcode patches from the net:
2723 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
2724 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
2725 missing altogether - they are added here. From Bruce Bauman.
2726 * mips-opcode.h: The low mask for C0 instructions was too small.
2727 From Garrett Lau. I modified the fix to check the entire 32-bit
2730 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
2733 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2735 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
2737 * dbxread.c (read_type): Pointer subtraction (value_sub in
2738 valarith.c) sometimes failed because the types of the
2739 pointers being subtracted were not identical.
2740 These differed because dbxread.c was allocating pointer types
2741 using dbx_alloc_type+smash_to_pointer_type instead of
2742 lookup_pointer_type. I failed to find a justification for the
2743 former, so I changed it to use the latter. Similarly, I
2744 replaced smash_to_function_type by lookup_function_type,
2745 and smash_to_reference_type by lookup_reference_type.
2747 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
2748 _initialize_mipsread): corresponding changes.
2750 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
2752 * source.c (mod_path): Do tilde_expand on each component of the path,
2753 rather than on the (list of) paths as a whole.
2754 (print_source_lines): Set first_line_listed in addition to
2755 current_source_symtab and current_source_line. If the source was
2756 not findable, after a "dir" command to fix the problem,
2757 a "list" would get the wrong lines.
2759 While I was there... (gnu):
2761 * dbxread.c (read_type): Change error to complaint.
2763 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2765 First attempt at detailed understanding of symbol table memory alloc.
2767 * dbxread.c (dbx_symfile_read): Free our string table if we
2768 aren't the mainline. Free the "info" struct since we're done with
2770 (init_psymbol_list): Free any previously allocated psymbol lists.
2771 (): FIXME: Should realloc-down the psymbol lists when done reading
2772 the main symbol file?
2774 * symmisc.c (free_symtab): Free fullname field too.
2776 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
2777 (REGISTER_ADDR): Make result type unsigned int.
2779 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
2780 define REGEX must also define REGEX1 (its dependency).
2782 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2784 * tconfig/i960: No longer works, points you at vxworks960 or
2787 * xgdb.c, XGDB-README: Remove file. Users can get the much
2789 * Makefile.dist: Remove all trace of xgdb.
2791 * breakpoint.c (breakpoint_1): Pass demangle arg to
2792 print_address_symbolic.
2793 (clear_breakpoints): Remove unused function.
2794 (breakpoint_re_set_one): Guts of breakpoint_re_set.
2795 (breakpoint_re_set): Use catch_errors to do them all anyway.
2797 * gdb-int.texinfo (Host versus Target): Add section on what is
2798 a "host" feature versus what is a "target" feature.
2800 * infcmd.c (path_command, path_info): Handle the PATH variable
2801 (object search path) as conveniently as the source search path.
2802 * environ.c (set_in_environ): Set some vars in GDB's environment,
2803 in addition to the child's. PATH, G960BASE, G960BIN for starters.
2804 * source.c (mod_path): New function, from guts of
2805 directory_command, modifies a path. Used by path_command.
2806 (directory_command): Call it.
2807 * defs.h (strsave): Declare.
2809 * utils.c (sevenbit_strings): Add new printing option.
2810 (printchar): Use it.
2811 (strsave): Provide this handy helper routine.
2812 (set_width_command): Rename set_screen_width_command.
2813 (_initialize_utils): "set screen-width" => "set width";
2814 "set screen-height" => "set height"; add sevenbit-strings.
2816 * infcmd.c (do_registers_info): Print floating point registers
2817 in raw hex as well as float format, regardless of whether it is
2818 a "virtual" convertible register.
2819 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
2820 regs as a double, just in case it's being used that way.
2821 * values.c (unpack_long): Comment on array/function coercion.
2822 (unpack_double): Argument is in target byte order now. For
2823 integer arguments, just call unpack_long and float the result.
2824 * m68k-tdep.c: include defs.h for "const" handling.
2825 * remote-nindy.c: Use ieee-float stuff.
2826 (nindy_fetch_registers): Unpack double regs to host double, then
2828 (nindy_store_registers): Pack extendeds to host double, flip
2829 around by misusing unpack_double, send as target double.
2831 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
2832 zero, as when stopped at the first instruction of a process.
2834 * blockframe.c: Fix filename in comment (param.h => tm.h).
2835 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
2836 * tm-68k.h: Fix typos.
2838 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
2840 Changes from a bringup on the DEC Vax under Ultrix 4.0.
2842 * coredep.c (fetch_core_registers): Pass end-address of register
2843 section to register_addr as expected. Don't call supply_register
2844 if we'd just pass it garbage.
2846 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
2848 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
2850 * target.c (push_target, target_info): Cast enums to int for < or
2853 * stack.c (print_frame_info): Identify source file & line
2854 even if we can't print it.
2856 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
2858 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
2860 Clean up IEEE floating point support.
2862 * ieee-float.h: New file.
2863 * ieee-float.c: Write real routines to convert between host
2864 doubles and various target IEEE extendeds.
2865 * m68k-xdep.c: Eliminate assembler code for extended floats.
2866 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
2867 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
2868 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
2869 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
2870 double_to_ieee_extended.
2871 * i960-tdep.c: Define ext_format_i960.
2872 * m68k-tdep.c: Define ext_format_68881.
2873 * sparc-tdep.c: Define ext_format_sparc, though unused.
2874 * Makefile.dist (HFILES): Add ieee-float.h.
2875 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
2878 Obsolete the "coffstrip" program in favor of using BFD's strip.
2880 * nindy-share/coffstrip.c: Remove file.
2881 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
2882 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
2883 * tconfig/nindy960: Remove reference to coffstrip.o.
2885 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
2887 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2889 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
2890 * dbxread.c: Remove static symfile_bfd.
2891 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
2893 * inftarg.c (child_detach): Pop the child_ops vector if the
2894 detach is successful.
2895 * remote-nindy.c (nindy_create_inferior): Don't push a new
2896 nindy_ops since nindy uses the same one for execution and memory
2898 * core.c (core_ops): Use child_attach and child_create_inferior
2899 rather than default attach and create_inferior functions.
2901 Handle floating point registers in core files.
2903 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
2904 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
2905 This version untested since BFD doesn't yet support sun3 core
2907 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
2908 conventions. Fix comments and style. This version has not
2909 been compiled yet, since we have no HP inhouse.
2910 * core.c (get_core_registers): Look for two sections, ".reg"
2911 and ".reg2", and pass both to fetch_core_registers sequentially.
2913 Revise directory path yet again.
2915 * source.c (forget_cached_source_info): Not static any more.
2916 (init_source_path): New default source path is "$cdir:$cwd".
2917 (dir_command): Handle variable arguments ($cdir, $cwd).
2918 (source_info): Print "Compilation directory" rather than
2919 "Originally compiled in" to remind people of $cdir.
2920 (openp): If the path contains $cwd, use current directory.
2921 (open_source_file): If compilation directory is known, replace
2922 first $cdir in path with the compilation directory.
2923 (print_source_lines): Even if we can't print the lines, set the
2924 current symtab and line for future commands like "info source" or
2925 "breakpoint". Also, error message now contains the file name,
2926 line number, and file access error message.
2927 (_initialize_source): Fix help text to describe changes.
2928 * main.c (cd_command): Forget cached source info when we chdir.
2929 * utils.c (strstr): Add simple implementation.
2931 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
2933 * coffread.c (read_one_sym, init_linetable, init_stringtab):
2934 Byte-swap COFF symbol tables if necessary when reading them in.
2935 Use complain() to replace error message in one spot. Needs
2936 corresponding change in bfd/coff-code.h to make some symbol
2937 swapping routines non-static.
2939 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
2941 Merge changes from Eirik Fuller, for UTek.
2943 * defs.h (errno): Add declaration.
2944 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
2945 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
2946 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
2947 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
2948 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
2949 declarations of errno.
2951 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
2953 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
2954 <rpc/rpc.h> and <rpc/types.h>.
2956 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
2958 * i960-tdep.c (examine_prologue): Add new argument limit,
2959 which stops the scan at the end of the prologue, or at the PC.
2960 This fixes a problem where it walks down into the code for the
2961 user's statements if that code looks like function prologues.
2962 Mark Fox and I have been bouncing this code back and forth, making
2963 small changes to it. Callers changed to match.
2965 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
2967 Cleanup for gdb-3.94 release final:
2969 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
2970 the .c files from vx-share and nindy-share, from the various
2971 macros, since they are not found via ALLDEPFILES.
2972 (SFILES): Add tm-i960.h.
2973 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
2974 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
2976 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
2977 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
2979 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
2981 * am29k-tdep.c: Add contribution line.
2982 (examine_prologue): Cache information about function prologues in
2983 the misc-function-vector to avoid lots of references over the
2984 serial line while examining instructions.
2986 * core.c (core_close): New function made from cleanup_core.
2988 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2989 remote-vx.c, remote.c, target.c, target.h,
2990 Update target_ops vector to add attach, close, and load entries.
2991 Use add_syms_addr_command, not add_file_addr_command, for
2992 add_file. Break out close routine from existing code.
2994 * dbxread.c (really_free_pendings): Don't free pending_blocks;
2995 they are in an obstack.
2996 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
2998 (define_symbol): Add symbol type parameter; change callers;
2999 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3000 it to influence the symbol class on the i960.
3001 (define_symbol): Swap LOC_CONST's into target byte order.
3003 * exec.c (exec_close): New function.
3004 (exec_file_command): Call it.
3006 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3007 Fix byte order of frame pointer.
3008 (read_var_value): Result of 0 if var's value can't be found,
3009 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3010 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3011 (locate_var_value): Use read_var_value and use its lazy address
3012 as the location of the var's value. Lint.
3014 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3017 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3018 obsolete Intel versions in favor of vxgdb versions.
3019 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3020 code dealing with byte order of values, which Intel did in host byte
3021 order rather than gdb-4's target byte order.
3022 (i960_frame_chain_valid): Move to nindy-tdep.c.
3023 (examine_prologue, skip_prologue, frame_find_saved_regs,
3024 frame_args_address, leafproc_return, saved_pc_after_call,
3025 pop_frame): Add vxgdb versions from Mark Fox.
3026 (examine_prologue, frame_struct_result_address): Add code
3027 to deal with the saved value of G13 (struct return address
3029 (frame_args_address): Modify Mark's version to prefer the
3030 saved value over the current value in the topmost frame.
3031 Cache result in the frame info to avoid performance hair in
3033 (print_fault): Add gdb960 code for printing faults.
3034 (_initialize_i960): Actually call check_host.
3036 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3037 add stub routines. FIXME, these currently just return zero!
3039 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3040 (attach_command): Call target_attach, not target_open, now.
3042 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3043 (child_attach): Rename from child_open.
3044 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3045 don't confuse it with a zero step_resume_break_address.
3047 * inftarg.c (child_detach): Eliminate inferior_pid test.
3048 (child_files_info): Clean up message a bit.
3049 (child_ops): Use child_attach, not child_open, to attach.
3051 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3052 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3053 findvar.c to here, since it depends on the contents of the
3054 shadow_contents of breakpoints, but keep if #if 0 since it is
3057 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3060 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3061 (ptype_command, display_command): Eliminate have_inferior_p and
3062 have_core_file_p in favor of target_has_stack or
3063 target_has_execution.
3064 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3065 code for actually finding the values of arguments, though we still
3066 keep track of the maximum stack offset for use in printing unnamed
3067 arguments. Handle missing FRAME_ARGS_ADDRESS.
3069 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3070 (struct nindy_regs): Define registers passed to/from nindy.
3071 (nindy_fetch_registers, nindy_store-registers): Translate between
3072 nindy and GDB formats for the registers.
3073 (dcache_init): Statically allocate the cache, since it was being
3074 allocated by a malloc that was never freed anyway.
3075 (nindy_create_inferior): Error, not core dump, if no exec file.
3076 (nindy_before_main_loop): Use target_load, not target_add_file.
3078 * remote-vx.c (net_load): Specify large timeout for load
3079 requests. Allow user to break out with INTERRUPT.
3080 (net_break): Remove useless code, clean up. Change callers.
3081 (parse-args, skip_white_space, find_white_space): Clean up arg
3082 parsing to cope with quoted strings.
3083 (net_wait, net_quit): Never call error, just return status.
3084 (vx_read_register, vx_write_register): Cleanup status checking.
3085 #ifdef the code based on which CPU we are using (960 or 68k),
3086 FIXME, this should be completely general but it isn't yet.
3087 (vx_xfer_memory, vx_resume): Cleanup status checking.
3088 (vx_run_files_info): Improve message.
3089 (vx_load_command): Renamed from vx_add_file_command. Allow load
3091 (net_ptrace): Remove unused routine.
3092 (vx_wait): Adopt code from vxgdb960 to cope with broken
3093 connections to target machine and prompt to disconnect. Remove
3094 debug printouts. Map some EVENT_'s to SIGnals.
3095 (add_symbol_stub, vx_open): Print names of object files we found,
3096 and "ok" if we read their symbols OK. Clarify output in general.
3097 (vx_attach, vx_detach, vx_kill): Add these commands.
3098 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3099 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3100 "info files" output, and create_inferior, since we already have
3103 * stack.c (frame_info): Replace Frame_unknown with 0.
3104 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3105 (return_command): Pop until the PC matches as well as the FP,
3106 so it works even if the FP is shared with another function,
3107 as in "frameless" or "leaf" procedures.
3109 * symfile.c (load_command): renamed from add_file_target_command.
3110 (add_syms_addr_command): renamed from add_file_addr_command.
3111 (add_syms_command): Stub to call target_add_syms.
3112 (_initialize_symfile): Change command names and descriptions,
3113 add-file => add-syms, and load from alias to its own command.
3115 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3116 maybe_kill_then_create_inferior): Default for attempts to start
3117 a process, if one is already running, is to ask about killing
3118 it and retry if yes.
3119 (upstack_create_inferior): #if-0 it, strata obsolete it.
3120 (push_target, unpush_target, pop_target): to_close() a target
3121 before unstacking it.
3122 (target_info): Renamed from target_files_info.
3123 (_initialize_targets): Rename "i files" as "i target", accessible
3126 * target.h: Improve comments about the target_ vectored routines.
3128 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3129 Convert commenting style to standard GNU style.
3130 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3131 (SKIP_PROLOGUE): No longer a no-op.
3132 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3133 (*_REGNUM): Sort register numbers.
3134 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3135 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3136 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3137 are now 10 byte extendeds, not 8 byte doubles.
3138 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3139 for nindy versus vxworks targets. FIXME, this should possibly go
3140 in the target vector.
3141 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3142 frame_saved_regs and arg pointer with each frame.
3143 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3144 (FRAME_ARGS_ADDRESS): Use cached result.
3145 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3146 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3147 (PRINT_RAMDON_SIGNAL): Call print_fault.
3148 (POP_FRAME): Now works.
3150 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3151 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3152 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3153 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3156 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3157 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3159 * valarith.c (value_subscripted_rvalue): Avoid handling
3160 floats and doubles specially; it gave alignment errors. Lint.
3162 * valops.c (value_of_variable, value_of_this): Error if unknown
3165 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3166 to avoid alignment problems.
3167 (value_print): Handle unknown value address.
3168 (cplus_val_print): Two args are ignored; remove them. Change caller.
3169 (val_print): Use unpack_long rather than pointer-deref.
3172 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3173 to avoid alignment problems.
3174 (value_being_returned): Error if return value unknown.
3175 (set_return_value): Add bogosity warning, FIXME. *
3177 * TODO: A woman's work is never done.
3179 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3180 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3181 Add ieee-float.o to OBS.
3182 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3183 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3184 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3186 Changes to generalize the VxWorks RPC protocol slightly, to handle
3187 i960 as well as 68000.
3189 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3190 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3191 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3192 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3193 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3194 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3195 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3196 so they will move in target byte order rather than network
3197 byte order (happens to be the same).
3199 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3201 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3203 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3206 Add contribution lines to various files, showing where they
3209 * breakpoint.c (break_insn, check_break_insn_size,
3210 read_memory_nobpt): Remove to mem-break.c.
3212 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3215 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3216 entry has bad register number. This change is not
3217 tested in this release, FIXME.
3219 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3222 * value.h: Force value's contents field to be aligned to hold
3223 at least a double or a long long (if supported). This avoids
3224 doing bcopy's in and out of the contents field.
3226 (step_1): Avoid coredump under obscure circumstances when we
3229 * symtab.h (misc_info): Add field to misc function vector for
3230 any kind of cached information the target code desires. AMD
3231 29000 uses this to avoid repeating examine_function_prologue's.
3233 * coffread.c: Lint. Remove static symfile, read_section_header.
3234 core.c (have_core_file_p): Lint: remove.
3235 expprint.c (print_subexp): Lint.
3236 infptrace.c, valops.c, valprint.c: lint.
3238 Roll in changes from vxgdb-5.0.1:
3240 * symtab.h: Comment byte order of each address class. Add
3241 LOC_LOCAL_ARG for frame-relative args (960).
3242 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3243 symtab.c, symmisc.c: ditto.
3245 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3247 * remote.c (remote_resume): Error if resume with a signal.
3249 * symfile.c (prim_record_misc_function): Clear misc_info.
3250 (fill_in_vptr_fieldno): Check stub type of arg.
3252 * valops.c (value_cast): Avoid looking up names of types whose
3253 name we don't know, to prevent coredump. Sun CC produces typedef
3254 rtx and the name of *rtx is zero...
3256 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3258 Roll in changes from final AMD 29000 port (Tiemann).
3260 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3261 for ../include/a.out.encap.h. This might not work now that BFD
3262 is separately compiled. Instead, BFD support for encap will have
3263 to translate machine type 29k into the right COFF_MAGIC.
3265 * infcmd.c: Remove references to inferior_pid that aren't used
3266 in actual ptrace calls; use target_has_execution, etc.
3267 (have_inferior_p): Remove function.
3268 (program_info): Print target info rather than "process number";
3269 avoid gratuitous messages unless from_tty.
3270 (run_stack_dummy, finish_command): Set proceed_to_finish.
3271 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3272 main.c: Lint. Lose have_inferior_p().
3273 inferior.h (have_inferior_p): Remove, lint.
3274 (proceed_to_finish): Add flag to ask that all regs be saved
3275 by normal_stop, for the few commands that need it, speeding up
3276 serial I/O. Add comments to stop_registers.
3278 * remote-eb.c: Remove newline from breakpoint message we grep
3279 for. Never time out when running the user program.
3283 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3285 Roll in changes from vxgdb-5.0.1:
3287 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3288 symbol in its raw form, we are processing an unlinked ".o" file.
3289 See if the target environment has assigned it an address, using
3290 target_lookup_symbol (VxWorks does), and enter it into the symtab
3293 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3294 68k versions for a simpler version that assumes zero FP at bottom.
3295 Fixes bug of truncated stack reports.
3297 * target.h (target_lookup_symbol): Define this routine's args
3298 and result, finally.
3300 * target.c (nosymbol): Default routine for target_lookup_symbol.
3301 (target_default): Default lookup_symbol and call_function too.
3302 (files_info): Only print has_all_memory warning if a non-dummy
3305 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3306 vx_convert_from_virtual): If target does not have floating point,
3307 zero register "values", and avoid doing cross-net conversions.
3308 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3309 (vx_open): Rearrange code that attaches to target and reads
3310 symbols for all loaded modules, to work if some of the modules
3311 are not accessible. Add symbol_stub() and add_symbol_stub()
3312 as callbacks from catch_errors(). Allow connect attempt to be
3313 interrupted painlessly with ^C (FIXME, there are still some bugs
3314 if the interrupt happens during symbol reading.). Print
3315 final message with puts_filtered, since symbol messages are
3320 * main.c (catch_errors): Only print errstring if non-null.
3321 (command_loop): Avoid an ioctl per command to test ISATTY.
3323 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3324 (vx_xfer_memory): Return correct result!
3325 (vx_files_info): Indicate whether target has float or not.
3326 (vx_lookup_symbol): Complain, not error, if target gone.
3327 (vx_open): Print "Connected" msg before disabling immediate-quit.
3328 [FIXME: lookup_symbol and vx_open changes need testing.]
3330 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3331 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3332 contributor lines and update copyrights to 1991.
3334 Changes from an attempted H-PUX host port:
3336 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3337 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3338 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3339 * remote-vx.c: include <sys/time.h> for HPUX.
3340 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3341 "core_file_command" routine to BFD regime. May not work yet.
3343 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3345 * xgdb.c: Replace X10 version with some VJ version.
3346 (FIXME: Its copyright assignment is not on record.)
3347 * xgdb.c: Update include files to X11R4 (Xaw crud).
3348 (xgdb_display_source, create_text_widget): fix call to
3349 get_filename_and_charpos. Rewack source window stuff for X11R4
3350 (gleaned from include files, and "nm's" of binary libraries, since
3351 I had no doc available).
3352 (append_selection, append_selection_word): Disable with FIXME
3353 since R4 changed interface here.
3354 (create_buttons): Add back the old set of buttons.
3355 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3357 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3358 Roll VERSION to 3.94 (not yet final though).
3360 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3362 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3363 obstack_int_grow, obstack_int_grow_fast): Eliminate
3364 cast on left of assignment, which gives MIPS cc fits and is
3367 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3368 F_ALIAS. Use printf, not fprintf, when not passing a file
3370 (compare_opcodes): Check that identical instructions have
3371 identical opcodes, complain otherwise.
3373 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3374 was reported by Roland McGrath.
3375 (unimp): Only match if exactly zero instruction. (Roland)
3376 (branches and traps): Generate all variations of these
3377 instructions with macros, based on a single call that defines
3378 each condition name and its binary representation.
3379 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3381 * valprint.c (val_print_fields): Take, and use, format parameter.
3382 This means that "p/x struct" again prints the elements in the
3383 desired format. Changed callers.
3385 * stack.c (frame_info): Use filtered output, and indicate wrap
3386 points. Remove kludgy formatting designed to avoid line wrap.
3388 * utils.c (wrap_here): If the line is already full (because
3389 we had printed a long indent or long wrapped string), do an
3390 immediate newline-and-indent.
3392 * m68k-pinsn.c (print_insn_arg): Bugfix from
3393 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3394 instruction is incorrectly disassembled as bkpt #8.
3396 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3397 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3398 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3399 and then will dump core (sometimes). I traced it back to an
3400 uninitialized symfile_name in psymtab_to_symtab.
3401 (const_vol_complaint): Add quotes to message.
3402 (define_symbol): Only believe line number if gcc_compiled.
3403 Avoid allocating symbol if we will not return it.
3405 Add target strata support so that newly established targets go
3406 into their right place in the target stack (e.g. a new exec file
3407 doesn't wipe out the ability to access the running process).
3409 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3410 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3411 and initialize it properly in all the targets.
3413 * target.h: Document strata. Change return type of push_target.
3415 * target.c (nomemory): new function for dummy memory access.
3416 (tcomplain): Rename complain, now also used in symfile.c.
3417 (push_target): Push targets within strata. New return value shows
3418 whether new target is on top of stack or not. Always keep dummy
3420 (target_files_info): Ignore dummy target.
3422 * core.c (core_open): Warn user, and skip accessing file, if the
3423 core target is not the topmost target in the stack.
3424 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3427 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3428 target_ops, it doesn't belong there since we have no regs there.
3429 Change name of target from machine => memory to clarify.
3431 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3433 * Freeze version 3.93 for release.
3435 * Makefile.dist: Handle vx-share and nindy-share subdirs
3436 properly when building gdb.tar.Z.
3438 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3439 printed in various places, so I could change just one copy.
3441 * dbxread.c, coffread.c: Change references to bfd->iostream
3442 to cast to FILE *, now that BFD avoids needing types defined
3443 in other header files.
3445 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3447 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3448 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3449 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3450 (actually gcc -Wall).
3452 * dbxread.c: Remove first_global_sym, last_global_sym, since
3453 they are never referenced.
3455 * defs.h (baud_rate): Declare.
3456 main.c: Define it, and add the -b option to set it.
3458 * gdb-int.texinfo: Add text on how to define a new host or target
3459 architecture, prompted by Per Bothner's questions about MIPS
3462 * gdb.texinfo: Document "complaints". Change doc of -q since
3463 gdb no longer prints the copyright and blurb if you specify a file
3464 name to be debugged (just like Emacs). Add doc for Nindy-specific
3465 command line flags for specifying target serial port and such.
3466 Update copyright to 1991.
3468 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3469 has taken over for us the job of ripping up executable files. The
3470 crud caused Per Bothner's port to not compile.
3472 * infrun.c (normal_stop): Avoid printing "Program exited
3473 normally" if we are in batch mode. This allows a GDB which
3474 executes a program on a target system, to behave like a Unix
3475 command (input from stdin, output to stdout, no extraneous
3478 * main.c (main): Allow additional machine-dependent command line
3479 options to be specified with the ADDITIONAL_OPTIONS,
3480 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3481 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3482 processing to occur just before the main loop with
3483 BEFORE_MAIN_LOOP_HOOK.
3484 (main): If a "core file" argument is specified, and it is not a
3485 core file, try it as a process ID to attach.
3486 (symbol_completion_function): Attempt to cope with
3487 "show screen-" TAB, not very successfully. This needs more work,
3489 (batch_file): New function, returns whether we are reading
3490 commands from an interactive tty on stdin, or from somewhere else.
3491 Called by normal_stop since it doesn't get from_tty passed down
3492 to it like many commands do.
3494 * remote-nindy.c: Handle command line options for nindy
3496 (nindy_before_main_loop): Prompt user for tty name if they
3497 don't specify it before getting to the interactive command loop.
3499 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3500 and -r command line options. Also add hook before main loop
3501 to make it easy to specify a tty.
3503 * TODO: More things to do, one done.
3505 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3507 * dbxread.c: Make complaint() calls pass pointer, not struct.
3508 Add complaints about badly formatted C++ type information
3509 (const/volatile indicator, and parse errors resulting in
3510 error_type). Fix C++ virtual member fn comment.
3511 (read_struct_type): Avoid bumping pointer if we got a parse
3512 error; this prevents our walking beyond the end of a string.
3513 Terminate loop on null char as well as semicolon.
3514 (process_one_symbol): Fix the LBRAC fix so that it uses the
3515 last previous SLINE, FUN, or SO record's PC address. C++ debug
3516 symbols did not have SLINE records in a useful order compared
3517 to the LBRAC records.
3518 (define_symbol): Handle "catch" records.
3520 * symtab.c (check_stub_type): Added new complain
3521 `stub_noname_complain' and added a consistency check to
3522 keep the debugger from crashing when finishing from an
3523 exception frame. A real fix will be needed later.
3525 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3527 * infcmd.c (attach_command): Make global.
3529 * Makefile.dist (REMOTE_OBS): Make these compile by default,
3530 but make them easy to comment out. Perhaps later they should
3531 be enabled by what CPU you configure for? FIXME.
3532 (VERSION): Roll to 3.93.
3533 (pinsn.o): Remove rule for obsolete file.
3534 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
3536 Run down a problem that manifested by printing the wrong function
3537 name in stack traces of read_ofile_symtab. Turned out that the
3538 problem was the SunOS 4.1.1 (and previous) C compiler outputs
3539 the LBRAC symbol with an address in the *data* segment, which
3540 blew our binary search through the blocks.
3542 * dbxread.c: Use the complain() facility consistently to bitch
3543 about problems in the symbol file we are reading.
3544 (finish_block): Add code to check the nesting of the blocks;
3545 complain and Procrust them to fit if wrong.
3546 (make_blockvector): Check the order of the blocks, complain
3547 [but don't cope] if wrong.
3548 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
3549 symbols to be sure their PC value is greater than the last SLINE
3550 (line number) symbol we've seen, complaining and adopting the
3551 SLINE PC value if wrong.
3553 * symfile.h (struct complaint, complaint_root, complain,
3554 clear_complaints): Add.
3555 * symfile.c (complain, complaint_root, clear_complaints): Add
3556 facility to deal with non-fatal complaints and to regularize their
3558 (symbol_file_add): Clear complaint counters to allow new complaints.
3559 (initialize_symfile): Add 'set complaints' and 'show complaints'.
3561 * dbxread.c (dbx_symfile_read): Remember the address and size
3562 of the string table for the main symbol file, so we won't read it
3564 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
3565 to avoid reading the string table yet again. Lint.
3566 (throughout): Improve filtered output, including word wrap.
3567 (read_range_type): Improve Bothner's fix to handle other types too.
3569 * utils.c: Improve line wrap implementation. Handle unlimited
3570 width by making chars_per_line unsigned.
3571 (puts_filtered): New, easy, function.
3573 * defs.h (puts_filtered): add.
3575 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
3576 call the identical sort_symtab_syms() in symfile.c instead.
3578 * expread.y: Suggest the `file' command rather than `symbol-file'.
3580 * command.h (enum var_types): Add zinteger for seroable
3582 * command.c (do_setshow_command): Handle var_zinteger. Restructure
3583 nested if's into a switch.
3585 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
3586 we did not stop because of a breakpoint (it must have been for
3587 some other reason, like a "stepi"), so don't print anything.
3589 * symtab.c: Include <sys/types.h> all the time. Now that BFD
3590 doesn't include <sys/types.h>, old SunOS's require it for
3593 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
3595 A test port of gdb-3.92.6 to the Sony NEWS.
3598 Don't normally link in remote- or vx stuff.
3599 Some of it doesn't compile, and it wastes space for 99% of the users.
3600 Remove reference to no-longer-used HAVE_VPRINTF.
3601 Fixed BFD_DEP typo to BFD_DIR.
3603 Fix cast in arg to bfd_h_getlong.
3604 Make char *prefix be const.
3605 Fix how certain range types are mapped into builtin unsigned int types.
3607 Remove 2 #includes. They cause errors (on Sony, at least),
3608 and aren't needed (they wern't in earlier versions).
3610 print_address_symbolic should never demangle labels
3611 (since it prints *assembler-level* labels).
3613 [This was superseded by the change to printcmd below.]
3616 Add some "volatile" return types to avoid warnings.
3617 If MISSING_VPRINTF add vprintf function and not just macro
3618 (since vprintf is used in printcmd.c).
3620 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
3621 (The latter isn't grokked by some PCC-based compilers.)
3623 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
3625 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
3626 * nindy-share/coffstrip.c
3627 Added some forward declarations (otherwise, gcc complains
3628 about implicit extern redefined as static).
3630 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3632 Changes inspired by Per Bothner:
3633 * printcmd.c (print_address_symbolic): Take additional parameter
3634 specifying whether to demangle.
3635 (print_address): Pass in asm_demangle to control demangling.
3636 (print_address_demangle): New fn, takes explicit arg to control
3638 * utils.c: Add new vars demangle and asm_demangle, and let them
3640 (fputs_demangled): If !demangle, just print the argument.
3641 (fprint_symbol): If !demangle, just print raw symbol.
3642 * valprint.c (val_print): Call print_address_demangle rather than
3643 print_address, to cause demangling to depend on the global
3644 rather than assembler-level demangling setting.
3645 * WHATS.NEW, gdb.texinfo: Document.
3647 * main.c (show_command): Show all settings if no arg.
3648 (initialize_main): Make "info set" the same as naked "show".
3649 * command.c (cmd_show_list): Handle prefix commands in the
3650 list, and print the name of the setting as well as its English
3651 description and value.
3653 Allow gdb functions to specify where a line should wrap if it
3654 exceeds the size of a terminal line. Use it to make the output
3656 * utils.c (set_screen_width_command): New fn, mallocs a buffer
3657 of the right size when screen width changes.
3658 (set_screensize_command, screensize_info): Remove #if 0'd fns.
3659 (wrap_here): New fn, indicates a point in the output where we
3660 should wrap the line rather than just letting it overflow at a
3662 (fputs_filtered): Implement wrapping.
3663 (n_spaces): New fn, returns a pointer to N spaces.
3664 (print_spaces_filtered): Use n_spaces.
3665 * defs.h (n_spaces): Declare.
3666 * stack.c (print_frame_info): Wrap with 4-space indent after
3667 fn name and before filename and line number.
3668 * printcmd.c (print_frame_args): Wrap with 4-space indent
3669 before each argument name is printed.
3670 * valprint.c (value_print): Wrap with no indentation before
3672 (val_print_fields): Wrap with indentation relative to nesting
3673 level before each field name.
3674 (val_print): Wrap with nesting indentation before array elements.
3675 * command.c (do_setshow_command): Avoid extra newlines,
3676 wrap with 4-space indent around values printed, end with period.
3677 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
3679 * breakpoint.c (breakpoint_1): Implement addressprint for
3680 "info breakpoints" display. Change file name and line number
3681 format to " at file:nnn" rather than " (file line nnn)".
3682 * gdb.texinfo: Document.
3685 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3687 Frozen for gdb-3.92.6 release.
3689 README, WHATS.NEW: Update for 3.92.6 release.
3691 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
3692 coffread.o from configs since it is now built by default.
3693 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
3694 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
3695 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
3696 from configs since it is now built by default.
3698 Makefile.dist: Update for release 3.92.6. Handle files that
3699 have been moved to ../include, ../getopt, or ../bfd. Add
3700 saber.suppress and tests directory. Add config.status to
3701 the release (it will say "none").
3703 coredep.c: Minor formatting fixes.
3705 These changes were made in early December but only checked in now:
3706 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
3707 nindy-share/nindy.c: lint
3708 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
3709 register values coming back from the target; we store values
3710 in target byte order everywhere.
3712 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
3714 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
3716 * valprint.c (cplus_val_print, val_print_fields): New functions,
3717 which print C++ objects. They conspire to avoid printing a
3718 virtual base class more than once, following all the twists and
3719 turns of C++ virtual base rules.
3720 (val_print): Call the above rather than do it by hand.
3722 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
3723 symbol file, not for added files like shared libs. This really
3724 needs to be generalized to a timestamp per file.
3726 * core.c (cleanup_core): Avoid coredump if no core file.
3728 * config.gdb: Accept -host or -target in place of +host or
3731 * coffread.c (find_linenos): Avoid desupported BFD interface
3732 to line numbers. We still read them manually rather than using
3733 BFD's "generic" features.
3735 * gdbrc.tex, threecol.tex: Add GDB reference card and its
3737 Makefile.dist: Add refcard to OTHERS list for creating tar files.
3739 * Makefile.dist: Eliminate use of $< in explicit targets.
3741 * readline/Makefile: Use $< rather than $*.c, which does not
3742 include the VPATH in GNU Make.
3744 * tconfig/i960-bout, tconfig/i960-coff: These are identical
3745 copies of tconfig/i960, added for global configuration
3746 compatability. All i960 versions can read both coff and b.out.
3748 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
3749 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
3752 * TODO: Think of more things to do.
3754 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
3756 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
3757 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
3758 64-bit float conversion.
3760 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
3761 equivalent to sun?os4 so global config works.
3763 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
3765 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
3767 * main.c: Only declare linesize once; declare pagesize not at
3768 all, since it is never used.
3769 (main): Clear newly allocated line before it is used.
3771 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
3773 Further stabilization for the Intel 960.
3775 * Makefile.dist: Parameterize the location of the "include"
3776 and "bfd" directories, as well as "getopt". Add symfile.c.
3777 Link in both dbxread and coffread. Fix up "make depend" to
3778 rewack the locations of include, bfd, and getopt in its output.
3780 * README: Document moving include files, improve some of
3783 * coffread.c: Move common code out to symfile.c. Change
3784 symbol_file_command style interface to use new *_symfile_init
3785 and *_symfile_read interface under BFD. Use BFD internal
3786 info to locate line table, symbols, etc.
3788 * core.c (core_fetch_registers): Rename to get_core_registers
3789 to avoid confusion with fetch_core_registers.
3790 (register_addr): Move to coredep.c, which is already machine
3791 dependent. This leaves core.c pretty clean of dependencies.
3793 * coredep.c (register_addr): Accept this routine from core.c.
3795 * dbxread.c: Move common code (with coffread.c, etc) into new
3796 symfile.c. Each psymtab now contains a pointer to the
3797 format-dependent function that knows how to read it in. Make
3799 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
3800 (process_one_symbol): Add code to complain about a "compiler bug
3801 we muzzle here", if we actually see it.
3803 * eval.c (evaluate_subexp): Insert missing "break" statements
3804 in code that determines whether a variable is an lvalue in
3805 memory, register, or whatever. I detected this via a compiler
3806 bug in which it *almost* mashed out the whole switch statement.
3808 * gdb-int.texinfo: Add minor sections on configuring gdb for
3809 release, and about the README file.
3811 * infcmd.c (registers_info): Fix formatting somewhat. Still
3812 not as pretty as before, but it handles byte swapping.
3814 * remote-nindy.c: If data cache routines are interrupted while
3815 waiting for the remote end, be sure that any uninitialized cache
3816 blocks are on the free list, not on the valid list!
3818 * symfile.h: Flesh out this header file with all the various
3819 routines and variables that have been merged in from dbxread.c
3820 coffread.c, and symtab.c to symfile.c.
3822 * symfile.c: New file, containing code common to dbxread.c,
3823 coffread.c, and some code from symtab.c. All generic code for
3824 reading symbol files should be in here now.
3825 (unrecord_misc_function): Remove unused function.
3827 * symtab.h: Remove file-reading things to symfile.h.
3829 * symtab.c: Remove file-reading things to symfile.c.
3831 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
3832 to decode i960 fault types.
3834 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
3835 target.c: Change type of the "resume" function from int to void,
3836 since its result was never used.
3838 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
3840 * main.c: Replace "stupid" with "caution"; you now "set caution
3843 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
3845 * infcmd.c (do_registers_info): Call val_print to deal with the
3846 byte order of the registers being printed. FIXME, this makes
3847 the formatting of the output uglier.
3849 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
3850 defined, call it for signals the debugger doesn't itself use.
3851 The i960 uses this for more detailed fault information.
3853 * remote.c (remote_open): If arg is null, print help rather than
3856 * sparc-xdep.c (register_valid): Avoid declaring size, since
3857 various modules will think of various sizes depending on the
3858 architecture of their tm-file. FIXME, we need protection against
3859 actually entering one of those modules, which would clobber
3860 storage if not for the target architecture compiled into gdb.
3862 * stack.c (up_command, down_command): Always print the frame
3864 (up_silently_command, down_silently_command): New commands
3867 * i960-pinsn.c (reg), i960-tdep.c: Lint.
3869 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
3870 more parameters than it used to.
3872 * findvar.c (registers): Increase slop to 256 bytes, which should
3873 protect us against even most RISC machines with large register
3875 (locate_var_value): Move declaration inside related ifdef.
3877 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
3878 throughout, to avoid throwing away buffered input from the board.
3879 (nindy_wait): Supply_register takes addr_of_value, not value.
3880 (i960_print_fault): Renamed from i80960_fault.
3881 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
3882 (nindy_store_registers): Avoid regs_changed stuff, just stuff
3884 (nindy_create_inferior): Don't bother to write PC_REGNUM since
3885 we can set the PC in the call to proceed(). Unpush nindy_ops
3886 before pushing it on top, to avoid message to user. Eliminate
3887 commentary from Unix machines that just misleads here.
3888 (reset_command): Fix error message to suggest target command.
3890 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
3892 Release 3.92.5 as frozen.
3894 Stabilize the merged release...with help from lint, Saber C,
3897 Everywhere: Add include files needed to declare return types
3898 of functions called.
3900 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
3902 * breakpoint.h: Add undeclared breakpoint functions, and some
3903 functions for display handling since I couldn't think of a better
3906 * breakpoint.c (insert_breakpoints): Make code for disabling
3907 shared library bkpts more likely to work. It's used when we
3908 rerun a program and stop before the shared library has been
3910 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
3911 cast from pointer, so it squeezes through catch_errors.
3912 (bpstat_stop_status): Fix logic broken some time ago. We now
3913 always create a bpstat if the stop address matches a breakpoint,
3914 even if we don't stop there -- just like the old code used to do
3915 before I got my fingers into it (sigh).
3916 (breakpoint_1): Print "ignore count" after "stop only if"
3917 condition, since that's how it actually works.
3918 (mention): Handle watchpoints as well as breakpoints.
3919 (watch_command): use set_raw_breakpoint and mention to do most
3920 of the work (and initialize all the fields!). Only pass one
3921 arg to parse_c_expression, since that's all it takes.
3923 * command.c (not_just_help_class_command): Rename arg to args
3924 since we ignore "unused argument" warnings on vars named "args".
3925 inflow.c (child_terminal_info): ditto.
3926 infptrace.c (kill_inferior): ditto
3927 main.c (catch_errors, version_info, quit_command, pwd_command,
3928 source_command, dump_me_command, editing_info,
3929 set_history_size_command, set_history, show_history,
3931 stack.c (locals_info): ditto
3932 target.c (target_files_info): ditto
3933 valprint.c (set_input_radix, set_output_radix): ditto
3935 * core.c: Remove old variables for handling core and exec file
3936 sections (data_start, data_end, stack_start, stack_end,
3937 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
3938 text_end, exec_data_start, exec_data_end, text_offset,
3939 exec_data_offset, data_offset, stack_offset). They're
3940 superseded the more general build_section_table and
3942 (get_exec_file): Mention the `file' command.
3943 (read_memory_check): Rename to memory_error, and only call it
3944 in the case of an actual error.
3945 (read_memory, write_memory): call memory_error.
3946 (core_fetch_registers): Register section name is ".reg".
3948 coredep.c: Remove a bunch of crud now that all this file does
3949 is pull the registers out of a core file.
3950 (fetch_core_registers): Rewrite to actually work, I hope.
3952 dbxread.c: Use a.out.gnu.h, not system a.out, now.
3953 Replace index() with strchr(). Remove all the pre-BFD macro
3954 definitions for accessing the symbol file.
3955 (struct dbx_symfile_info): Encapsulate the information that
3956 dbx_symfile_init needs to pass to dbx_symfile_read in this
3959 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
3960 dbx_symfile_discard): Rearrange symbol file reading to divide
3961 the format-specific part from the format-independent part,
3962 leaving the format-independent part such as file name expansion
3963 and opening in symtab.c. This replaces
3964 partial_symbol_file_open and partial_symbol_file_read.
3965 Symbol_file_read, add_file, add_file_target_command,
3966 add_file_addr_command move to symtab.c. Pass an explicit
3967 "mainline" flag for when reading the main symbol table, rather
3968 than relying on the offset address to be zero or nonzero.
3970 (dbx_symfile_read): Don't allow void *'s to be printed as
3972 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
3973 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
3974 macro" debug version really work.
3975 (read_dbx_symtab): Remove unref'd parameter inclink.
3976 Avoid swapping N_SLINE symbols, for speed.
3977 Merge N_TEXT!N_EXT case with the other external symbol
3978 definitions' case. Add comments.
3979 (start_psymtab): Allocate the symfile name in the psymtab on
3980 the psymbol_obstack, rather than using the caller's storage.
3981 (end_psymtab): Only allocate a dependencies list if there are
3983 (psymtab_to_symtab_2): Use BFD when reopening file to read
3984 its symbols for real.
3985 (read_struct_type): Add FIXME comments where it needs work
3987 (read_huge_number): Add FIXME about overflows.
3988 (read_range_type): Add FIXME about comparing a long to 1<<32.
3990 * coffread.c: Minor changes to move things closer to the new
3991 regime with symtab.c and dbxread.c Major work is still needed
3994 * exec.c (exec_file_command): Remove old variables (see core.c
3996 (xfer_memory): If memory transfer is right at the end of a
3997 section, don't lose.
3999 * findvar.c (get_saved_register): If value is in a real
4000 register, LVAL is lval_register, not lval_memory.
4002 frame.h: Declare print_sel_frame and record_selected_frame.
4004 gdb-int.texinfo: New file, for GDB internals documentation.
4005 Very simple, unformatted doc of cleanups is there for now.
4007 gdbcore.h: Remove obsolete variables that described a.out
4008 section addresses and offsets. (See core.c above.)
4009 Declare fetch_core_registers and registers_fetched.
4011 getopt.c: Declare char *alloca(); even on SPARC.
4013 infcmd.c (run_command): Call target_kill rather than
4015 (step_command, next_command, stepi_command, nexti_command):
4016 Declare from_tty parameter even though we don't use it.
4017 (run_stack_dummy): argument BUFFER is a char array, not
4018 a pointer to REGISTER_TYPE.
4019 (finish_command): using_struct_return needed a value *,
4020 not a struct symbol *.
4022 * infptrace.c (child_xfer_memory): To avoid dependency on
4023 where sections are in memory, try PT_WRITE_D and if that fails,
4024 try PT_WRITE_I. Most Unixes don't care which you use.
4026 * infrun.c (step_resume_break_shadow): Change to array to
4027 match other breakpoint shadow storage.
4028 (clear_proceed_status): Pass address of bpstat to
4029 bpstat_clear, not the bpstat itself.
4030 (child_create_inferior): FIXME comment about if the child
4032 (start_inferior): Remove old function.
4033 (child_open): Use target_kill rather than kill_inferior.
4034 (wait_for_inferior): Ditto.
4035 (insert_step_breakpoint, remote_step_breakpoint): Use
4036 new step_resume_break_shadow.
4038 * inftarg.c (child_wait): If all child processes die,
4039 pretend that the one being waited for exited with signal 42.
4041 * main.c (command_line_input): When scanning for comments,
4042 don't coredump on unclosed quotes.
4043 (quit_command): Use target_kill rther than kill_inferior.
4044 (_initialize_main): Rename class_user from "user" to
4047 * printcmd.c (print_command_1): Initialize "fmt" if no format
4048 is specified by the user.
4049 (print_frame_args): Only add to args_printed if we are
4050 actually fetching args from the stack (avoiding undefined
4052 (_initialize_printcmd): Remove bogus \{ from string.
4054 * remote-eb.c (eb_open): Avoid coredump on no argument.
4056 * remote-nindy.c: Bring out of Intel environment into new
4057 target environment. Remove all conditional compilation on
4058 I80960. Massive hacking throughout.
4059 (nindy_xfer_inferior_memory): New routine stolen from
4061 (nindy_create_inferior): New routine pieced together, probably
4062 not quite working yet.
4063 (nindy_ops): New target_ops struct for nindy.
4065 * remote-vx.c: Use write_memory rather than target_write_memory
4066 to get error checking.
4067 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4069 (vx_create_inferior): Use target_terminal_ours...
4071 * signame.c (_initialize_signame): Always initialize, since
4072 we need the table for things other than psignal.
4074 * solib.c (solib_add): Use symbol_file_add, not add_file.
4075 (solib_address): Return boolean result rather than struct
4076 pointer which nobody else knows the type of.
4078 * sparc-tdep.c, valops.c: Use write_memory rather than
4079 target_write_memory, to get error checking.
4081 * stack.c (locals_info, catch_info, args_info,
4082 get_selected_block, frame_command, up_command): Use
4083 target_has_stack, rather than have_inferior_p or
4086 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4088 * symfile.h: New file, defining the interface between the
4089 generic and object-file-specific symbol reading code.
4091 * symtab.c: Move generic symbol-reading interface to symtab.c,
4092 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4093 table to map BFD targets to symbol-reading modules in GDB.
4094 Change index to strchr.
4095 (lookup_struct_elt_type): Use error() rather than hand-made
4096 simulations thereof.
4097 (lookup_partial_symbol): Speedup slightly when length == 0.
4098 (symbol_file_add): New function.
4099 (symbol_file_command): Call it.
4100 (symfile_open, symfile_init): New function.
4101 (add_file_target_command, add_file_addr_command): moved from
4104 * target.c (target_command): use target_kill.
4106 * target.h (target_files_info): Don't declare, never called
4109 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4110 files to determine stack end address.
4112 * valarith.c (value_x_binop, value_x_unop): Change error message
4113 to be more useful. Pass proper argument to value_struct_elt.
4115 * valops.c (value_assign): FIXME comment that long long
4116 bitfields will break here.
4118 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4119 Update `make saber_gdb' to work better.
4121 * TODO: A woman's work is never done.
4123 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4124 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4125 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4126 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4127 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4128 valops.c, valprint.c, exec.c: Lint.
4131 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4133 Continuing Intel 960 port merge of GDB.
4135 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4136 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4137 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4138 Wack over "make depend" so it handles files in subdirectories
4139 vx-share, nindy-share, bfd, and in the current directory.
4141 * blockframe.c (get_prev_frame_info): Remove fatal error
4142 if stack not defined.
4144 * core.c (core_open, core_detach): New functions that handle
4145 the old "core-file" command as "target core" and "detach" instead.
4146 (core_file_command): Call them.
4147 (core_xfer_memory): Use common routine xfer_memory.
4149 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4150 dbxread now uses bfd for everything but symbol reading itself.
4151 BFD internals are used to drag out the relevant file offsets.
4152 (partial_symbol_file_open): Change args all around for BFD.
4154 * symtab.c: Rename "value" to "val" everywhere, so we can
4156 (symbol_file_command): New command, moved from dbxread.c
4157 and coffread.c. It uses BFD to read the file, then vectors
4158 based on its type, to dbx or coff symbol readers.
4159 * symtab.h: Extern a few vars for symbol_file_command.
4161 * target.h: Breakpoint takes a char * save area, not a char **.
4163 * valprint.c (val_print): When unpacking bitfields, offset
4164 the address in gdb of the value, if it is declared with a shorter
4165 type. Remove the last "runtime kludge test" of host byte order.
4167 * utils.c: Remove old my_bfd_read routine.
4169 * stack.c (frame_info): Use target_has_stack. Print program counter
4170 register's actual name rather than "pc", since it's called the
4171 "ip" (instruction pointer) on the i960 (sigh).
4173 * target.c (target_command): Add command for selecting a target
4174 type and calling its open routine. This is used for initiating
4175 communication with a particular target, in a generic way.
4177 * tm-i960.h: Update for modern gdb. Remove semicolons from
4178 various macros. Handle reading struct return convention, and
4179 error-out attempts to return structs with the "return" command.
4180 Be sure gdb doesn't think we know how to call functions in the
4183 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4184 to i960_xxx in lower case.
4185 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4186 not being defined yet.
4188 * remote.c (remote_open): Call start_remote to initialize
4189 wait_for_inferior during open.
4190 (remote_xfer_inferior_memory): Return length written rather
4193 * remote-vx.c (target_command -> vx_open): Use new generic
4195 * remote-eb.c, inftarg.c, exec.c: ditto.
4197 * infrun.c: Fix comments.
4198 (attach_program -> child_open): Use new generic target command.
4199 (wait_for_inferior): Clear saved register values before target_wait,
4200 so target_wait can set some of them if convenient.
4202 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4203 Return success indicator, not void.
4204 (child_xfer_memory): Avoid fetching initial word if we'll
4205 overwrite it anyway.
4207 * infcmd.c (attach_command): Use new generic target open routine.
4208 (_initialize_infcmd): Update doc on attach and detach commands.
4209 (do_registers_info): Merge in a byte-order problem as a FIXME
4212 * findvar.c (find_saved_register): Avoid problem in current frame.
4213 (read_relative_register): Ditto.
4214 (write_register): Convert byte order on the way out.
4216 * exec.c (file_command): Add.
4217 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4218 (xfer_memory): Common function between core_xfer_memory and
4220 (exec_xfer_memory): Use it.
4222 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4224 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4225 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4226 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4228 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4230 Merge Intel 960 port of gdb, continuing...
4232 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4233 symbol_file_command): Pass from_tty arg to hush 'em up.
4235 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4236 Add magic numbers for 960 COFF format.
4238 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4240 Merge Intel 960 port of gdb, from Intel "1.2" release.
4242 CHANGE_LOG entries from their port, which was based on
4245 Thu Sep 6 11:02:22 PDT 1990
4246 Remove temp file if download is interrupted.
4248 Wed Aug 1 09:08:33 PDT 1990
4249 Now uses binary protocol to talk to NINDY.
4250 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
4251 Times out after 5 seconds when trying to talk to NINDY.
4253 Tue May 29 12:54:49 PDT 1990
4254 Added variable baud rate (-b switch).
4255 Source code reorganization.
4257 Thu Apr 26 11:09:55 PDT 1990
4258 More cleanup of batch mode; specifically, execute "-s", "-e", and
4259 "-se" switches as soon as they are encountered on the invocation line.
4261 Fri Apr 20 13:47:15 PDT 1990
4264 Thu Apr 19 09:54:28 PDT 1990
4265 Add 'reset' command.
4267 Wed Apr 18 09:48:07 PDT 1990
4268 After opening remote tty, wait for 1 second to go by without input
4269 from it before trying to talk to NINDY (fixes problems with the
4270 Heurikon HK80/V960E).
4272 Mon Apr 4 16:33:05 PDT 1990
4273 Some output was not being suppressed in 'batch' mode.
4275 Thu Mar 22 15:31:11 PST 1990
4276 Ask user if old symbol table should be deleted when new file is
4279 Allow user to run a program downloaded before gdb960 was brought up.
4281 Correct "exec-file" help message for i80960 context.
4283 Correct bug in calculating user space address: could occasionally
4284 corrupt user program.
4286 Make sure to zero low-order bits in rip's because of bug in 960CA
4287 A-step part: could cause operation faults when "next"ing across
4290 Correct bug that made it impossible to get source line numbers for
4291 code loaded at addresses higher than 0x7fffffff.
4293 Wed Jan 10 12:43:22 PST 1990
4294 Open remote tty for exclusive use.
4296 Fri Jan 5 12:14:42 PST 1990
4297 Correct disassembly (CA manual was right after all):
4298 opcode for sysctl is 0x659
4300 Mon Oct 23 12:03:04 PDT 1989
4301 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4303 Mon Oct 16 14:15:09 PDT 1989
4304 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4306 Mon Oct 2 15:56:31 PDT 1989
4308 Added 960CA disassembly support.
4310 To simplify maintenance:
4311 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4313 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4314 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4315 - made disassembly interface identical to that in gdmp960.
4319 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4321 * target.h: Allow targets to stack. Add target_has_memory,
4322 _registers, etc. Restructure memory access and "info files"
4323 to walk the target stack.
4324 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4325 target.c: Change tables to match target.h.

4330 * remote-eb.c: New memory regime, new info files.
4331 * remote-vx.c: New memory regime, new info files. Now use
4332 separate targets for VxWorks attachment to machine, and
4333 actually running a process under VxWorks, since one has
4334 stack & execution & regs and the other doesn't.
4335 * remote.c: New memory regime, new info files.
4336 * sparc-xdep.c (fetch_core-registers): New memory regime.
4337 * target.c: New routines and support for stacked targets,
4338 new memory regime, new info files regime.

4342 including use of the new BFD (binary file) library.
4343 * gdbcore.h: Add struct section_table.
4344 * exec.c (build_section_table): Iterate all sections and
4345 record what gdb needs to know about them.

4352 * dbxread.c: Quick changes to make it compile with new BFD.
4353 * utils.c (error): Avoid using bfd_error in generic routines.
4355 * core.c (core_fetch_registers): Get from the ".regs" section of
4357 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4359 * inferior.h (attach_flag): Export.

4367 since been deleted, such as temporary breakpoints.
4368 infcmd.c (program_info): ditto.
4370 * core.c (core_file_command): Display the frame where the core
4375 * remote-vx.c (target_command): Merge in target command from
4376 targ-vx.c. A few other cleanups.
4378 * TODO, Projects: Lots more stuff to do...
4380 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4382 Massive changes to wall off the remote-debugging interface
4383 behind a function vector. The port to handle VxWorks targets
4384 is also part of this.
4386 All files: Replace references to renamed functions,
4387 remove references to remote_debugging, remove references to
4388 have_include_file, have_core_file in favor of target_has_stack,
4389 target_has_memory, etc.
4391 * Modularize the breakpoint interface.
4392 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4393 a breakpoint instruction.
4394 breakpoint.c: struct breakpoint's shadow_contents now sized as
4396 (insert_breakpoints): Vector to target to install breakpoints.
4397 (remove_breakpoints): Vector to target here too.
4398 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4399 sparc-tdep.c (single_step): Use new breakpoint interface for
4400 the single-step breakpoints.
4401 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4402 New file, contains routines to insert and remove breakpoints by
4403 reading out the old contents and later replacing them. This is
4404 how ptrace breakpoints work, and many remote systems as well.
4406 * tm-vxworks68.h: New config file, overrides a few things for
4407 Wind River's preferences.
4409 * target.h: New file, for transfer vector used to talk to the
4410 inferior (child, attached, core, exec, remote, etc). All accesses
4411 to the thing being debugged should come through these vectors.
4412 target.c: New file, routines to handle transfer vector.
4413 (various files): Add transfer vectors XXX_ops for the various
4414 targets and pseudo-targets (core files, etc) we support.
4416 * breakpoint.c (bpstat_stop_status): Further explorations of
4417 watchpoints and why things don't work all the time.
4418 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4420 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4421 the local gdbinit if it doesn't already have it.
4423 * core.c (core_ops): add and install.
4424 Allow core debugging without exec file.
4426 * dbxread.c (free_and_init_header_files): Merge two fns.
4427 (end_symtab): Free named symbol table when a new version comes in.
4428 (read_dbx_symtab): Relocate all kinds of symbols with base
4429 address. First step toward handling different text, data, bss
4431 (add_file_addr_command): Renamed add_file_command.
4432 (add_file_command): Vector to remote handler.
4433 Add "load" as an alias for "add-file" command.
4435 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4436 non-returning functions.
4438 * exec.c: Add exec_ops, and push it as a target when an exec
4441 * infcmd.c (run_command): Pass executable file name and arg list
4442 separately when starting an inferior. Permit "run" when no exec
4443 file is specified, for VxWorks.
4444 (detach_command): Move to child_detach in inftarg.c.
4446 * inftarg.c: New file. Unix-child-specific routines, and the
4447 child_ops structure.
4449 * inferior.h (registers): Export "registers" as the way for
4450 target dependent register handlers to find gdb's local copy of
4451 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4452 since it is now used by places that want wait_for_inferior to
4453 handle the grunge but want to see every trap from the inferior.
4455 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4456 Eliminate remote_debugging hooks in terminal handling.
4458 * infrun.c: Replace start_inferior with child_create_inferior.
4459 Move all the hair of Unix shells and ptrace idiosyncracies into
4460 child_create_inferior, so remote handlers don't have to deal.
4461 Remove running_in_shell. Rename stop_after_attach to
4462 stop_soon_quietly, and use it in a few other places where we want
4463 to just call wait_for_inferior and get control back on the first
4464 trap. trap_expected now never takes a value > 1.
4465 (init_wait_for_inferior): Initialize static vars when a new
4468 main.c (gdbinit): Add new hook for .gdbinit file name, let
4469 it be overridden by config files as GDBINIT_FILENAME.
4470 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4471 Both of these are used for VxWorks gdb.
4473 mcheck.c: rename include file "gmalloc.c" to avoid problems
4474 with system include file "malloc.c".
4476 param-no-tm.h: New include file, same as param.h but does not
4477 include the default "tm.h" file. This is used in files where
4478 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4480 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4482 remote-vx.c: New file, VxWorks remote debugging support. Uses
4483 RPC routines that are shared with the target system, in directory
4486 remote.c: Vectorize remote interface.
4488 source.c: Globalize source_path, and make an alias "l" for "list"
4489 since we now have the "load" command.
4491 sparc-xdep.c: Use new param-no-tm.h.
4493 symmisc.c (free_named_symtab): Add new function from Wind River.
4494 However, ifdef it out for now while we think about what it should
4497 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4499 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4500 non-Unix-children handle this with their own code in the target
4503 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4504 source and target lists. Add vx-share to default list of include
4505 directories. Add new files to src and target lists: mem-break,
4506 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4507 ${srcdir} versions of munch and createtags are used.
4509 * valops.c (find_function_addr): Split out of call_function.
4510 (call_function_by_hand): Rename call_function; this function
4511 calls functions in the target by laboriously patching the target
4512 word-by-word with the right stack, args, regs, etc.
4515 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
4517 Handle AMD 29000 a bit better.
4519 * remote-eb.c (readchar): Mask received char log to make it readable.
4520 (remote_start): Pass arguments down to executing program.
4521 Make startaddr unsigned.
4522 infrun.c (start_inferior): Accept args, pass them to
4524 infcmd.c (run_command): Pass args down to start_inferior.
4526 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
4527 the target object file format.
4528 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
4530 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
4531 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
4533 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
4535 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
4536 * TODO: We did a few things, we have more to do though.
4538 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
4539 * inflow.c (inferior_died): Clear deferred stores.
4541 * Debug problems with dummy frames and calls to the inferior.
4542 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
4543 * sparc-tdep.c (do_restore_insn): Simplify.
4544 (sparc_frame_find_saved_regs): Simplify and fix what we find.
4545 (sparc_push_dummy_frame): Simplify and fix what we push.
4546 (sparc_pop_frame): Slightly more hair here, deciding whether
4547 we are restoring a saved PC or returning to a return address in %i7.
4548 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
4550 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
4551 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
4552 * obstack.h (chunkfun): ditto.
4553 * defs.h (xmalloc, xrealloc): ditto
4555 * utils.c (quit): Grab the terminal from the child if necessary.
4557 * inflow.c (term_status_command): Rename to term_info, change
4560 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
4561 (is_delayed_branch): Speed up.
4562 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
4563 Still missing some float ops, and needs testing.
4565 * Support for input and output radixes other than base 10
4566 * defs.h (input_radix, output_radix): Declare.
4567 * expread.y (yyparse, parse_number): Handle changes of input
4568 radix, and ambiguous names-or-numbers in radixes >10.
4569 * printcmd.c (print_scalar_formatted): Print formatted hex
4570 numbers in varying column widths.
4571 * valprint.c (val_print): Use output_format to print scalar ints.
4572 (set_input_radix, set_output_radix, set_radix): Create.
4573 (set_output_radix): Set output_format from output_radix.
4574 (_initialize_valprint): add `set radix' but leave the others off.
4576 * main.c (execute_command): Let stupid questions be turned off.
4577 (_initialize_main): Handle "set stupidity", etc.
4579 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
4580 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
4582 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
4584 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
4585 bfd stuff is still screwed up, but with some manual work, it
4588 * breakpoint.c (bpstat_do_actions): Start over if a command
4589 proceeds the inferior, since the inferior will have stopped and
4590 will need to have its new stop-actions taken care of.
4592 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
4593 compiler fits, simplify it.
4595 * gdb.texinfo (directory command): Doc new dir command.
4596 source.c (directory_command): "dir" now puts things on the front
4597 of the path, moves dups up front, and handles multiple names
4598 on the command line, inserting each one in order. It also
4599 blows away cached line and full_filename info.
4601 * stack.c (backtrace_command): Skip "more stack frames follow"
4604 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
4605 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
4606 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
4607 The only odd one was Gould NP1, which had defined vprintf to
4610 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
4611 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
4612 variable, inspect_it.
4613 valprint.c (print_string, val_print): Use the global inspect_it
4614 to indicate whether to print in Epoch style or normal style.
4616 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
4618 * printcmd.c (call_command): add an alias for the "print" command
4619 which runs expressions and doesn't print the result if void.
4620 (print_command_1): implement it.
4622 * command.c: Remove #if 0'd code. Initialize all the fields
4623 in add_cmd (). Rename do_nothing_command to
4624 not_just_help_class_command, and make it externally visible.
4625 command.h: add user_commands to struct.
4626 * main.c (define_command): Don't overload c->function with a char
4627 string as well as a function pointer.
4629 * eval.c (evaluate_subexp): Reinstall tiemann changes to
4630 calling convention of value_struct_elt () that got dropped in
4633 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
4634 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
4636 * tm-sparc.h (POP_FRAME): replace some constants with defines.
4638 * sparc-xdep.c (store_inferior_registers): defer stores to regs
4639 until a good time (e.g. when we are about to run the child),
4640 saving ptrace calls.
4641 * infrun.c (proceed): handle DO_DEFERRED_STORES.
4642 * tm-sparc.h: define DO_DEFERRED_STORES.
4644 * sparc-xdep.c (store_inferior_registers): when storing float
4645 registers, don't store stack regs too. When storing the SP,
4646 however, DO store the stack regs too. This fixes a bug in which
4647 the dummy frame is not recognized when a call_function finishes,
4648 because its frame pointer (in the stack regs) was never
4650 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
4651 even though we don't know how to read them from an inferior.
4652 valops.c (call_function): Comment about storing SP.
4654 * infrun.c (save_inferior_status): Save away the original bpstat
4655 chain so it can be restored later. Install the copied version for
4656 use by whoever saved the status. It will be blow away by
4657 restore_inferior_status, and the original chain restored. This is
4658 important for people who have pointers into the original.
4660 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
4661 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
4662 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
4665 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
4667 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
4668 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
4669 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
4671 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
4673 * Merge Mike Tiemann's multiple inheritance changes from Sun.
4674 Store the baseclasses in a type struct starting from array element
4675 0 rather than from the unusual array element 1.
4677 dbxread.c: the above.
4678 (virtual_context): Add
4679 Read new debug information about which virtual function table
4680 a virtual function is from, and store it in fn_field.fcontext.
4682 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
4683 TYPE_FN_FIELD_STATIC_P.
4685 symtab.c: the above.
4686 valops.c: the above. Handle pointer casts of object *'s.
4687 (search_struct_method): Add.
4688 (value_struct_elt): First arg is now a pointer to a value, and is
4691 valprint.c: the above.
4692 values.c (value_virtual_fn_field): Add type arg. Handle
4693 offsetting to the proper object when calling virtual fns.
4695 (baseclass_addr): Add valuep arg.
4697 * README: Document the current state of BFD config (missing).
4698 * TODO, ChangeLog, Makefile.dist: Roll version.
4699 * WHATS.NEW: Add summary of changes since 3.5.
4701 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
4703 * dbxread.c (read_struct_type): Clear bit vectors whenever
4705 symtab.c (B_CLRALL): define.
4707 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
4708 using == rather than =. Huh... This fixes the dreaded problem
4709 wherein builtin_type_int becomes TYPE_CODE_FLT.
4711 * core.c (info_files): Show the inferior pid.
4713 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
4714 already knows how to look in the source directory.
4716 * Remove psymtab hair from many places. Remove duplicated code
4717 for searching symbol tables. Hide psymtabs from most places.
4718 Make it fast to get from a psymtab to its symtab.
4720 blockframe.c (blockvector_for_pc): Remove psymtab hair.
4721 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4722 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4723 dbxread.c: export psymtab_to_symtab, make it work if called N times.
4724 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
4725 new symtab completely. New psymtabs get symtab pointer
4726 initialized to zero. Remove MI warning printf.
4727 symtab.h: Comments. Add psymtab to symtab pointer.
4728 (PSYMTAB_TO_SYMTAB): New macro.
4729 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
4730 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
4732 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
4734 (print_frame_info): Avoid special-casing symbols that have not yet
4737 * source.c (open_source_file): Quick path if we have already
4738 located the source file by its full name.
4740 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
4741 find_pc_psymtab. When a name is found in the misc function
4742 vector, search the symbol table for its mangled name, not the
4743 name that the user typed.
4745 * bfd.h: Fix missing comment terminators, make #endifs match.
4747 * valarith.c (value_less): Handle unsigned int comparisons.
4748 Add FIXME about pointer compares, which assume host and target
4749 pointers are the same.
4751 * command.c (do_nothing_command): lint
4752 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
4753 fix comments on debug symbol format for visibility. Actually set
4754 visibility of symbols.
4755 main.c (echo_command): lint; use <readline/history.h>.
4756 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
4757 obstack.h (_obstack_blank): Rearrange pointer math to avoid
4758 pointing past end of allocated memory; saber complains.
4759 obstack.h: Declare the external functions that we use.
4760 valarith.h: use <string.h>
4761 solib.c (solib_add): lint.
4763 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
4765 * main.c (initialize_main): Default info_verbose to off, now that
4766 symbol reading is fast.
4767 (quit_command): Avoid clobbering exec_bfd while quitting.
4769 * Initial BFD (binary file diddling library) merger:
4770 coffread.c: Change AOUTHDR to struct exe_hdr.
4772 core.c: initialize initialized data at compile time.
4773 (core_file_command): Move from coredep.c, convert to bfd.
4774 (xfer_core_file): Convert to bfd.
4775 exec.c (exec_file_command): use bfd routines.
4777 mips-tdep.c: Remove exec_file_command and friends.
4780 * coredep.c: (fetch_core_registers) Convert core_file_command to
4781 fetch_core_registers.
4782 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
4784 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
4785 (my_bfd_read): More bogosity, which I don't think we call.
4786 (program_name): Remove this atrocity asap!
4788 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
4791 values.c: allocate_repeat_value was not clearing the
4792 optimized_out field.
4793 (value_static_field): minor stylistic fix (wrong macro was used).
4794 valops.c (value_struct_elt_for_address): didn't work for C++
4797 * signame.c (_initialize_signame): Initialize signal names once.
4799 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
4800 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
4801 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
4803 * remote-eb.c: Support user-settable baud rates on the serial port.
4805 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
4807 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
4809 * tconfig/sun3os4: Remove warning about native assembler,
4810 since it also occurs in the xconfig file.
4812 * findvar.c (registers): Allocate some slop after `registers'
4813 to prevent stray accesses from trashing the next variable.
4815 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
4816 on the sun-3, by changing the #ifdef from `sun3' (which is not
4817 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
4818 vars, which happened to follow `registers' in the executable.
4820 * readline/history.c (history_search): Heed gcc-2's advice
4821 and parenthesize && inside ||).
4823 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
4824 tm-29k.c: Insert FSF copyright headers.
4826 * remote-eb.c: Better comments.
4828 * Makefile.dist: Update to 3.91.6.
4829 * TODO: note PREPARE_TO_STORE problem.
4831 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
4833 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
4835 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
4837 * infrun.c (wait_for_inferior, at end): Don't set up
4838 prev_* if the inferior no longer exists.
4840 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
4841 CANNOT_EXECUTE_STACK.
4842 valops.c (call_function): Use it.
4844 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
4846 * inferior.h (PC_IN_CALL_DUMMY): New macro.
4847 infrun.c (wait_for_inferior, 2 places): Use it.
4849 * values.c (value_being_returned): Only use
4850 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
4852 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
4853 right thing for remote-eb.c.
4855 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
4856 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
4858 * blockframe.c: Put get_frame_saved_regs inside #if !defined
4859 (FRAME_FIND_SAVED_REGS).
4861 * findvar.c ({fetch,store}_registers): Check for
4862 REMOTE_{FETCH_STORE}_REGISTER macro.
4864 * findvar.c (get_saved_register): Add argument lval and
4865 change meaning of argument addr.
4866 findvar.c: Change calls to get_saved_register to reflect
4867 new calling convention.
4868 valops.c (value_assign): Use get_saved_register instead of
4869 find_saved_register.
4871 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4873 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
4874 an (uninitialized) pointer to one. Use "&" when passing it
4877 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4879 * coffread.c (getfilename): Use DGUX x_offset and x_name if
4882 * coffread.c (symbol_file_command): Put semicolon after
4884 Put safe_to_init_tdesc_context in #if defined (TDESC).
4885 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
4886 coffread.c: #include <sys/stat.h>.
4887 (read_coff_symtab): Typo: in_source_files -> in_source_file.
4888 Add missing ')' in check for "lc%" and friends. Remove
4890 Declare read_one_sym() at top of file.
4891 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
4892 MC68WRMAGIC can have the same value without causing a duplicate
4895 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
4897 * Allow a Makefile to be built without building the
4898 tm and xm file links that screw up builds in subdirectories.
4899 This is done with `config.gdb none', then you can do things
4900 like `make gdb.tar.Z'.
4901 * tconfig/none: Config file for no target system
4902 * xconfig/none: Config file for no host system
4903 * config.gdb: If no TM or XM files are called out by the
4904 host or target file, don't make links for them.
4906 * cplus-dem.c: Add documentation.
4908 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
4909 simple error, so the user's gdb doesn't crash due to some object
4910 file problem (e.g. somebody is rebuilding the file out from under
4913 * printcmd.c (print_address_symbolic): demangle the symbol.
4915 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
4916 Motorola copyrights in it. Make "make gdb.tar.Z" work.
4917 (alldeps.mak): sort and uniq all results from this; duplicates
4918 hose gdb.tar.Z link building. Remove RCS files from
4919 tconfig and xconfig. Add config files for sun386. Add
4920 a few odd files to OTHERS and HFILES.
4922 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
4924 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
4925 Roll version number to 3.91.5. Make lint work in bindir.
4927 * README: Document cross-debugging and new file structure.
4929 * blockframe.c: Lint. Include "value.h" to declare read_register.
4930 (find_pc_partial_function): remove duplicate line.
4932 * command.h: Lint. Declare error_no_arg and dont_repeat.
4934 * tm-news.h: Remove inadvertently duplicated stuff.
4936 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
4937 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
4939 * config.gdb: Allow `config.gdb host target' form. Clean
4940 up previous change that printed bogus messages when you just said
4943 * core.c: #include "command.h" for lint.
4946 * main.c: Remove some casts of enums. Lint.
4953 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
4955 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
4956 read it from memory. This will allow us to save ptrace calls
4957 eventually. Changed caller single_step too.
4959 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
4960 that we aren't going to use, saving many ptrace calls, especially
4961 when watchpointing or single stepping. Use some #define's for
4963 (store_inferior_registers): Ditto.
4964 (core_file_command): Use some #define's for constants.
4966 * tm-sparc.h: Add #define's for some register numbers, so we
4967 can eliminate the use of random constants in sparc-xdep.c.
4969 * stack.c (frame_command, print_frame_info, up_command,
4970 down_command) Remove frame_changed, since it
4971 causes a bug and doesn't seem to do anything useful. In some
4972 places it was used as a flag, in others as a stack level (?).
4974 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
4975 default is to use the portable (vprintf) version rather than the
4977 * xm-news.h (MISSING_VPRINTF): Add.
4979 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
4981 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
4983 * Remove stuff that forces -Bstatic linking of gdb, and warnings
4984 about linking debugged programs -Bstatic in the sun?os4 config
4985 files in tconfig and xconfig subdirectories.
4987 * main.c (main): Remove unreached exit(0) now that we exit
4990 * Create TODO file for online bug list. There are too many
4991 "little" bugs to keep track of on paper.
4993 * Change Projects file to refer to bug-gdb@cygnus.com
4994 rather than kingdon@ai.
4996 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
4998 * Makefile.dist (VERSION): 3.91.4 now.
5000 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5001 (condense_misc_bunches): Add sanity check that misc_count is
5002 the same as the number of symbols in the bunch.
5004 * coffread.c: rename init_misc_bunches. Pass an argument
5005 to condense_misc_bunches (a zero).
5007 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5008 every time we are called; don't rely on our caller to do it.
5009 (add_file): Remove call to init_misc_bunches.
5011 * mipsread.c: Only warn, don't error, if unknown symbol types.
5012 This keeps an old gdb from falling on its face if it sees newly
5013 extended symbol info. Rename init_misc_bunches.
5015 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5017 * Merge in changes from Per Bothner for DECstations and other
5018 MIPS stuff. The rest is Bothner speaking:
5020 The next message is a merger of Alessando Forin's mips port with
5021 mine. I've tried to use my good if biased judgment to get
5022 the best of both. It *does* need testing.
5024 Some of the changes are general, *not* mips-specific.
5027 Didn't believe in little-endian bit order.
5028 There are still inconsistencies about whether flags
5029 like BITS_BIG_ENDIAN are integer (#if ...) or
5030 boolean (#ifdef ...). I tried to paper over them.
5032 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5033 Moved some misc_function code that was common to
5034 {dbx,coff,mips}read.c to symtab.c.
5035 In the process, I think I cleaned things up a bit.
5036 At the same time, moved obsavestring and obconcat to symtab.c.
5039 Removed obsolete condense_addl_misc_bunches (use
5040 condense_misc_bunches(1) instead).
5043 Needed to include <sys/dir>, at least on DECstations.
5045 valops.c, mips-tdep.c, tm-mips.h:
5046 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5047 conventions (when STACK_ALIGN is insufficient).
5048 Needed on mips, where doubles need 8-byte alignment,
5049 but ints only need 4.
5052 Removed cruft that was not being used.
5053 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5056 Print $ before register-names (I think that makes things a little
5058 Never print two instructions, even if one delays.
5059 Removed hex-disassemble set_cmd. (This is not mips-specific,
5060 so I think the argument is whether it is generally worthwhile or not.
5061 I'm inclined to think not, given how easy it is to
5062 convert between radixes in gdb.)
5065 This is basically Alessando's code.
5066 It doesn't use obstacks; I changed it to use obstacks
5067 in a few minor places where using malloc causes a
5068 memory leak. (Probably, more places could/should be changed.)
5069 I added record_misc_function where it was missing.
5070 In symbol_file_command and add_file_command, I tried
5071 to make the code consistent with more recent versions.
5072 Minor sylistic changes in parse_procedure.
5073 Make a .gdbinfo. psuedo-symbol point back to the real
5074 procedure symbol (using the isym field).
5077 This is basically from my port, but with a lot of details
5078 and a number of routines merged in from Alessando's version.
5079 I basically used my code "raw" backtrace (use heuristics
5080 from the actual code, rather than symbol table info) - though
5081 the idea is Alessandro's. I feel my code is a little cleaner
5082 here, particularly in being a little more flexible, such as being
5083 able to handle gcc-produced code (which it now can).
5084 It also doesn't do frame caching (which is not useful
5085 more recent gdb versions).
5086 I also used my code for push_/pop_dummy, more or less.
5087 I tried to incorporate AF's code for testing sigtramp
5088 while backtracing; I probably got it wrong.
5089 Added mips_print_register, which tries to scrunch as much
5090 information as possible on a screen...
5091 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5092 under mips-pinsn.c), I don't see anything mips-specific here,
5093 and I don't see it being all that useful anyway.
5096 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5097 Use more register names (rather than hard-cases numbers).
5099 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5101 * Hack up 3.90.11 changes:
5103 * Makefile.dist (depend): parameterize $(GCC).
5104 Add solib.c and solib.o.
5105 (readline): Fix vpath for both absolute or relative SRCDIR.
5107 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5108 Also, let the part I didn't understand at least compile so
5109 I can test the rest. FIXME.
5111 * dbxread.c: Fix thinko using strcmp.
5112 (init_psymbol_list): declare static.
5113 (partial_symbol_file_open): Comment cleanups better, avoid
5114 cleaning up the string table since the caller will do that.
5115 Move the stat for mod time into symbol_file_command, temporarily.
5116 (There should be a mod time for each symbol file, eventually,
5117 to control its rereading. FIXME.)
5119 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5120 SunOS, which gives error for shared libs otherwise. (From
5121 Schaefer, probably FIXME needs work for portability.)
5123 * solib.c: Move #include "param.h" to work.
5124 Lowercase all the Uppercase Letters In the Messages.
5125 (find_solib): Clean up inferior_so_name for debug printouts.
5126 Allow no argument, to mean all shared libraries.
5128 * symmisc.c: include param.h to get CLEAR_SOLIB.
5130 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5132 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5133 to 3.90.11. ChangeLog entries below are from this.
5135 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5139 * Makefile.dist (HFILES): Add tm-sunos.h.
5141 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5145 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5147 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5149 * sparc-opcode.h Added single-operand version of rett.
5151 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5153 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5154 Put parens around gcc_p in expansion.
5156 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5158 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5160 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5162 * Changes for Sun shared libraries:
5163 blockframe.c (find_pc_partial_function): If a non-text symbol
5164 is found, set *address = pc - FUNCTION_START_OFFSET.
5165 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5166 Disable breakpoints instead of giving an error.
5167 source.c (select_source_symtab): Initialize cs_pst.
5168 symmisc.c: Call CLEAR_SOLIB if defined.
5169 symtab.h: Make text{low,high} CORE_ADDR not int.
5170 (psymtab): New field addr.
5172 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5173 (record_misc_function): Give correct type for N_DATA symbols.
5174 (condense_misc_bunches): do "misc_function_count = j" regardless
5176 Take code which is shared between symbol_file_command and
5177 add_file_command and put it into partial_symbol_file_{open,read}.
5178 Split add_file_command into add_file_command and add_file.
5179 Make psymtab_to_symtab read in the string table if the file
5181 Two new parameters to read_dbx_symtab and start_psymtab.
5182 tm-sunos.h: New file.
5184 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5186 * infcmd.c: Change cont_command to continue_command and "cont"
5189 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5191 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5193 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5195 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5196 size 1,2,4,8 rather than size < 8.
5198 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5199 as necessary, not just once.
5201 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5203 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5205 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5207 * tm-news.h: Add CALL_DUMMY_*.
5209 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5211 * config.gdb: In list_host, list_target, use ${i}, not $i.
5213 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5215 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5217 * sparc-opcode.h: Change all store floating-point state register
5218 instructions to have the right match & lose fields.
5220 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5222 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5224 config.gdb: If srcdir != ., create readline directory and
5225 copy a makefile into it.
5227 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5228 consistency with POSIX.
5230 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5231 when we exit its exp_valid_block.
5233 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5235 * Makefile.dist: Bump version to 3.91.3.
5237 * Clean up handling of breakpoint commands (somewhat).
5238 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5240 inferior.h: Add breakpoint_proceeded to inferior status struct
5241 and globals; save it and restore it.
5242 (clear_breakpoint_commands): Cleanup, remove old #define.
5244 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5245 (save_inferior_status, restore_inferior_status): handle it also.
5246 (proceed): Remove earlier code that set breakpoint_proceeded.
5247 It is now set only in clear_proceed_status.
5248 (clear_proceed_status): Cleanup, use bpstat_clear rather
5249 than clear_breakpoint_commands. No callers need the stop_bpstat
5250 between clear_proceed_status and proceed.
5252 infcmd.c: Add breakpoint_proceeded definition and comment.
5253 (cont_command, jump_command, signal_command): Move call to
5254 clear_proceed_status right next to call to proceed.
5256 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5257 caller's argument while running down the chain of breakpoints.
5258 Use new variable "breakpoint_proceeded" to determine when
5259 a command that it executes moves the inferior past the
5261 (bpstat_clear): Handle NULL argument.
5262 (bpstat_clear_actions): Avoid useless call to
5263 breakpoint_auto_delete.
5264 (delete_breakpoint): Clean up bpstat's that are pointing to
5265 the deleted breakpoint from the stop_bpstat chain.
5266 (breakpoint_auto_delete): Simplify.
5268 * Clean up handling of EOF, error on stdin, etc. This was
5269 prompted by a network problem that caused gdb to go into an
5270 infinite loop filling up its malloc'd memory.
5272 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5273 not clear_breakpoints_commands, which is now gone.
5274 (main): If command_loop returns (e.g. from EOF on stdin), do
5275 a quit_command (looping back to command_loop if quit_command
5276 doesn't really quit).
5277 (command_loop): check result from command_line_input and
5278 exit if it returns NULL, rather than passing the NULL to
5280 (gdb_readline): Free malloc'd result space before returning
5283 * utils.c (query): Handle C-d to mean "yes", just as if the
5284 input was not a terminal. Also avoid infinite loop if EOF
5285 occurs in mid-input-line before newline. This allows
5286 query to be used at EOF on stdin with reasonable results.
5288 * infrun.c (proceed): Set breakpoint_proceeded.
5290 * values.c (value_as_long): Avoid infinite recursion for enums.
5291 (_initialize_values): Fix typo in help msg (kingdon).
5293 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5294 RL_LIB for linking. This allows -lreadline for linking
5295 and nothing for dependencies, once readline is a real library.
5297 * config.gdb: Jim Kingdon: give useful error message if the
5298 host or target type is not recognized.
5300 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5301 it just defines it. Dumb, but deal with it.
5303 * Jim Kingdon suggests:
5304 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5306 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5308 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5310 * Clean up Bothner's changes.
5312 * blockframe.c (clear_pc_function_cache): New function.
5313 * blockframe.c: remake cache_pc_function_* static.
5314 * dbxread.c (symbol_file_command): remove references to
5315 cache_pc_function_* variables.
5316 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5317 * printcmd.c: Avoid kludging a global variable (addressprint)
5318 to avoid printing the address of a string twice. Instead,
5319 pass the format letter 's' down low enough that it can be seen
5320 to avoid this problem.
5321 (print_formatted): Pass format arg to value_print.
5322 (restore_addressprint): Remove function.
5323 (do_examine): Avoid hacking addressprint, cleanups and such.
5324 (print_frame_args): Add a comment to a Bothner change.
5325 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5326 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5327 to wipe out the values cached in blockframe.c.
5328 * symtab.c (find_method): Add comment saying how big you must
5329 allocate to be "big enough". Per being terse again.
5330 * valprint.c (val_print): Handle format letter "s" to print
5331 strings without addresses. Add comment to vtbl printing code
5332 which casts with wild abandon. Rearrange reference-printing
5334 @0xaddr: value (print w/addressprint)
5335 value (print w/~addressprint)
5336 @0xaddr (parameter lists w/addressprint)
5337 or nothing (parameter lists w/o addressprint)
5339 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5341 * Merge more changes from Per Bothner:
5343 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5344 annoying) that I tried to improve it. Here are my suggestions.
5346 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5349 Do automatic de-reference when taking the address of a reference.
5351 Don't deref_ref when printing parameter lists.
5353 More attempts at treating refernences properly.
5355 In val_print, if deref_ref==0, don't print dangling " = ".
5357 Add COERCE_REF macro, which de-references an REF.
5359 * Merge changes from Per Bothner:
5361 * Fixed (Sony news)-specific configuration problems.
5362 * Fixed other problems with using vanilla pcc and libc (enum problems;
5363 assumption that vsprintf exists).
5364 * Some major speed-ups (finc_pc_partial_function now caches a match;
5365 parsing avoids duplicate symbol_lookup calls).
5366 * Changed handling of baseclasses (no longer use baseclasses field
5367 of struct type, use the first n_baseclasses fields instead).
5368 * Various minor changes/fixes, most C++-related.
5371 Cache the most previous match from find_pc_partial_function.
5372 (Save both low and high ends of matching function's pc range.)
5373 This speeds up the loop of infrun.c:wait_for_inferior quite
5374 a bit, and makes step/next commands much zippier.
5376 Added an enum->int cast (otherwise, some compilers barf).
5378 No longer set baseclass offset to 0, since multiple
5379 inheritance now mostly works.
5380 Added a number of casts, to shut up compiler warnings
5381 (after stabs where made enums, not ints).
5382 When discarding a symbol table (in symbol_file_command),
5383 must clear the cache introduced in blockframe.c.
5384 Don't convert $vtbl_ptr_type to vtbl any more.
5385 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5386 Mask off sign bit emitted by g++ for virtual table offset.
5387 Set voffset to -1 (not 1) for static member functions.
5389 Changed parsing/lexing of names to avoid doing symbol lookup twice
5390 (once when lexing to determine symbol class, once for real).
5391 Now only call symbol_lookup once. Fields of 'this' win especially big.
5393 Subpress printing addr twice in the case of 'x/s addr'.
5395 lookup_basetype_type is no longer used.
5396 Add find_methods as recursive helper function to decode_line_1.
5397 This allows multiple inheritance to work.
5398 Also, once one or more matches has been found, do not look in
5399 base-classes. (Baseclass methods would be overridden, anyway.)
5401 Removed baseclasses array in struct type.
5402 Instead of using baseclasses[i], use fields[i-1].
5403 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5404 Changed sign convention of voffset (previous was inconsistent).
5406 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5408 Used to assume existence of vsprintf. Re-written to not need it
5409 if HAVE_VPRINTF is undefined.
5411 typecmp was too pessimistic. Made it less so.
5413 Don't print space after address.
5414 If vtable points to a misc symbol (with 0 offset), print it,
5415 since that indicates the actual class of the object.
5416 Changed ype_print_derivation_info to use new inheritance
5417 scheme (without baseclasses vector).
5419 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5420 Also, changes needed because TYPE_BASECLASSES were removed.
5422 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5424 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5427 If there is no path set, and the symbols don't indicate what directory
5428 a file was compiled in, look in the current directory. But either
5429 a path or a known compilation directory will prevent this.
5432 Three independent bug fixes:
5433 * Remove the #if 0 block that breaks some stuff.
5434 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5435 adapt gdb to either SunOS 4.0.* or 4.1.
5436 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5439 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5442 (type_print) Demangle the name being printed.
5443 (type_print_base) Handle botched demangling without coredump (tiemann).
5446 (check_stub_method): Document routine.
5447 (tiemann) fix bug for no-arg functions
5448 Avoid clobbering beyond end of malloc'd storage.
5449 Terminate the argument list properly.
5451 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5453 * Changes merged by John Gilmore:
5456 In breakpoint_1, use new print_address_symbolic instead
5457 of find_pc_partial_function. (This forces use of assembler-level
5458 addresses, and avoids misleading non-mangled source-level names.)
5460 Generalize ansi argument such that -1 means skip arglist totally.
5461 Removed global variable print_ansi_qualifiers (which made
5462 code non-reentrant), in favor of extra explicit arguments
5463 to internal routines.
5465 Add new helper function print_address_symbolic.
5466 Use find_pc_misc_function instead of find_pc_partial_function
5467 (since we want assembler-level symbols here).
5469 Print unknown function as just "f (...)", not "f (...) (...)".
5470 Use new fputs_demangled explicitly.
5472 Fixed a typing violation (problem: value.h cannot be imported
5473 without renaming many variable in this file).
5474 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5475 decode_line_1: Moved forward some never-reached code.
5476 Made decode_line_2 skip function prologues correctly.
5478 fputs_filtered should not demangle by default.
5479 Add new fputs_demangled to demangle on demand..
5481 Change value_struct_elt to use value_primitive_field (using recursive
5482 utility function search_struct_field). This allows foo.bar to work
5483 for multiple inheritance (so far only for data fields).
5484 Change check_field in the same way (recursive helper function
5485 to support multiple inheritance).
5486 (Note: there are more of these problems that I haven't fixed.
5487 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5488 value_of_this: 'this' symbol name is now just "this", note "$this".
5490 Don't print static members.
5491 Avoid printing "members of <type>" if there are none.
5492 Simplified type_print_derivation_info by merging duplicate code.
5493 Remove useless blank lines in type_print_base (ptype command).
5495 Added declaration of new routine value_primitive_field.
5497 Added value_primitive_field which is generalized version of
5498 value_field that can handle multiple inheritance (non-zero offsets etc).
5499 Re-implemented value_field to call value_primitive_field.
5501 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
5503 * infcmd.c -- insert else to avoid 'delete env' coredump when you
5504 delete the whole environment. Karl Berry reported the bug.
5505 * source.c - fix openp to avoid //'s in filenames, which
5506 trigger an Emacs bug causing it to not be able to find files
5507 when running gdb in a window.
5508 * dbxread.c - zap the #if 0 that botches the add-file code.
5509 It seems to work a lot better without all the code commented out.

5526 to remove signle step breakpoint instructions.
5527 * main.c added "-epoch" flag and "int epoch_interface" to main.c

5532 format controls easier
5533 * wait.h added a couple of undef's because we were getting
5534 complaints about WSTOPSIG and WTERMSIG begin redefined.
