10 * source.c (line_info): Peter Schauer fixes a bug I introduced in
13 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
17 * Makefile.in (VERSION): Set to 4.1.
18 * language.c (set_language_command): Print useful help message,
19 and restore the language string after giving help.
20 * valprint.c (typedef_print): Print typedef in C or M2.

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

141 (read_dbx_symtab, case N_DEFD): Ignore.
142 (read_enum_type): Recognize FALSE/TRUE enum as Modula-2 BOOLEAN.
143 (read_range_type): Rename MAX_OF_TYPE to MAX_OF_C_TYPE, etc.
144 #if 0 out its uses, though, since they set a dead value.
145 * coffread.c (end_symtab): Use allocate_symtab.
146 (process_coff_symbol): #if 0'd for functions and params as above.
147 (read_enum_type): Recognize Modula-2 BOOLEAN.
148 * symtab.c (add_param_to_type): #if 0'd function to add a
149 parameter type to a function type's field list.

220 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
222 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
223 entries are enclosed herein. Not all of these changes
224 have been merged into the master GDB sources -- check the
225 ChangeLog above here for the merge log.
227 Mon Jun 3 17:05:45 EDT 1991
229 m2-exp.y Created. Tested outside of GDB for a few days. Proper
230 operators were added, C specific operators and tokens
231 removed. yylex() revamped to some extent. Still things
232 missing from the grammar, such as sets.
233 Tested for two weeks in GDB v3.5.
235 Tue Jun 11 17:23:48 EDT 1991
237 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
238 so they are built-in. Sort of a hack.
240 Fri Jun 14 12:53:51 EDT 1991
242 m2-exp.y Added range checking for numeric constants. Any numeric
243 constant is assumed to be of builtin type INTEGER unless:
244 (1) it is octal or hexadecimal, in which case it is a
245 CARDINAL; (2) it is too big to fit into an INTEGER, in
246 which case it is a CARDINAL.
247 eval.c Added simple range checking for +, -, and * on integers.
248 Doesn't work very well for *, since 6 * 1,000,000,000 =
249 1,705,032,704, which fails the simple test of result >=
250 first_operand, no matter in what order the operands are.
252 Tue Jun 18 14:11:30 EDT 1991
254 Broke the parser into parts, one containing the C grammar and the other
255 containing code to be shared by all of the grammars.
257 The following files no longer exist:
262 The following files were added:
264 c-exp.y (The C grammar)
265 m2-exp.y (The Modula-2 grammar)
266 parser-code.c (Code that is shared by the above grammar)
270 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
271 now necessary to use the Bison compiler compiler, since it
272 will generate function/variable prefixes other than yy.
274 Tue Jun 18 16:47:49 EDT 1991
276 symtab.[ch] Added the external variable working_lang, than holds the
277 value of the current working language.
278 Added the ennumerated type language_mode, with the values
279 language_auto and language_manual, the former meaning that
280 GDB sets working_lang as needed, and the latter meaning
281 that the value of working_lang is totally under user
283 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
284 REAL, BOOLEAN and CHAR. Also added the type codes
285 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
286 utils.c Added set_language_command and show_language_command to
287 implement the GDB support commands "set language" and
289 expression.h A number of identifiers were added to the type exp_opcode
290 to facilitate Modula-2 builtin functions, integer
291 division, and array indexing.
293 Wed Jun 19 13:25:58 EDT 1991
295 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
296 if the language specified by working_lang requires the use
297 of strict typing of expressions. Eventually, even this
298 will be able to be changed by the user.
299 Added the macro RANGE_CHECK, which evaluates to non-zero
300 if the language specified by working_lang requires the
301 checking of a value against the domain of its type.
302 Eventually, even this will be able to be changed by the
304 language.[ch] Predicates involving types (simple_type, ordered_type,
305 same_type, integral_type, numeric_type, character_type,
306 boolean_type, float_type) are added. These predicates are
307 based on the current value of working_lang, and are handy
310 Wed Jun 19 15:39:34 EDT 1991
312 eval.c Added the function type_array_rank which computes the rank
314 valarith.c Added the funtion value_bool, which when given a integer
315 value.h value (ie. struct value *) as an argument, it returns a
316 boolean value (ie. struct value *) true if that integer
317 is non-zero, and a boolean value false otherwise.
318 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
319 will print out properly.
321 Wed Jun 19 16:36:34 EDT 1991
323 valops.c Added the function value_capitalize, which returns it
324 value.h argument capitalized if its argument is a lowercase
325 letter, or the argument unchanged if its argument is not a
327 valarith.c Added the function range_check_p, which returns non-zero
328 value.h if its value argument is between the integral bounds upper
330 Added the function range_check_enum_p, which makes sure
331 that its value argument is a valid member of the domain of
333 Added the function range_check_range_p, which makes sure
334 its value argument lies between the upper and lower bounds
335 of its type argument, which must be a ranged type.
336 Added the function check_array_index, which range and type
337 checks an index of an array.
338 Added the function value_multi_subscript, which computes
339 array[idx1,idx2...idxN], given a value array and an array
340 of values representing indicies.
341 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
342 unpack_long to work with TYPE_CODE_BOOL and
345 Wed Jun 19 18:04:08 EDT 1991
347 symtab.c Stored pervasive types in a structure and make
348 lookup_pervasive_type() a lookup function that was based
349 on working_lang. If lookup_pervasive_type() returned
350 non-zero, then that value was returned (a fix, since
351 before it simply wouldn't return the pervasive type.)
352 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
353 non-zero if the language specified by working_lang means
354 "conversion" when it says "cast".
355 valops.c Added the function value_real_cast(), which performs a
356 value.h *cast*, not a *conversion*, which is what value_cast()
357 does when it can. In particular,
358 value_cast(<float_type>,4) = 4.0, while
359 value_real_cast(<float_type>,4) = some mess.
360 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
361 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
362 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
363 and MIN on integral types. *NOTE*: These are currently
364 hardcoded to work only if there are 8 bits per storage
366 eval.c Made logical functions call value_bool to return a
367 properly typed boolean value, based on working_lang.
369 Thu Jun 20 11:55:27 EDT 1991
371 valprint.c Types now print out in a Modula-2 fashion. This works for
372 the cases when the type is printed out step-by-step, that
373 is, it doesn't work when the name of a structured type
374 (which includes the keyword "struct", etc.) is simply
376 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
377 since type specifications in C and Modula-2 are very
378 different. The C printing of a type is very recursive,
379 whereas in Modula-2 it is generally very simple. C has
380 type prefixes and suffixes, which have no real analogue in
381 Modula-2. Maybe type_print() should call a language
382 specific type printer. This is also advantageous if we
383 compile GDB to exclude some of the languages. We'll just
384 leave those functions out.
386 Thu Jun 20 16:57:10 EDT 1991
388 dbxread.c When reading the complete symbol table in (via
389 psymtab_to_symtab()), the number and types of function
390 arguments are added to a function type. define_symbol()
391 calls add_param_to_type() to accomplish this.
392 Assumption: when we come across a function definition
393 (N_FUN symbol with an 'f' or 'F' in the name), its
394 arguments will appear before another function definition.
395 When a function is found, a pointer to its type is placed
396 in the global in_function_type. Changes that
397 add_param_to_type() makes are to this global.
398 valprint.c The type of a function now includes (for Modula-2) the
399 types of its parameters.
400 eval.c Type checking and a check for the proper number of
401 arguments is now done for function calls. Not sure of the
402 impact this has on C++ member function yet.
404 Thu Jun 20 19:58:48 EDT 1991
406 valprint.c Rewrote the type printer. Broke it into two language
407 specific parts, adding the functions type_print_m2() and
409 An unfortunate consequence is this: if you debugging a C
410 program in Modula-2 mode (why?), info types does not work
411 well with regular expressions, since the types are printed
412 out in Modula-2 terminology, but stored in C terminology.
413 language.[ch] Added the functions new_type_last(), type_keyword(), and
414 type_sep() to aid in the printing of typedefs.
415 symtab.c Made the printing of typedefs as language independent as
416 possible through calls to new_type_last(), type_keyword(),
419 Fri Jun 21 11:50:26 EDT 1991
421 dbxread.c Check all incoming ennumerated types. If it looks like
422 Modula-2's BOOLEAN type, then change the type_code of the
423 type to TYPE_CODE_BOOL so we can process it as a boolean
425 valprint.c Replaced some of the 0x%x with calls to sprintf and
426 hexformat() in val_print().
427 language.[ch] Added the function hex_to_string(), which converts its
428 integral argument to a hexadecimal number (format is
429 language based) and returns the result as a string.
431 Mon Jun 24 12:25:07 EDT 1991
433 valprint.c Some functions call type_print_1() directly, instead of
434 value.h using type_print(), so they can specify where (column) to
435 print things. Since type_print() takes care of language
436 dependence, that needs to be called first. Added a
437 parameter depth to type_print() (so it is now like
438 type_print_1). Changed type_print to type_print_at, and
439 made type_print a macro that passes a depth argument of
441 symmisc.c Changed all calls to type_print_1 to calls to
443 Makefile.dist Made it possible to build GDB for a specific set of
444 depend languages. Do this by passing a definition for the macro
445 LANGS to make. LANGS should be a string containing a
446 space-separated list of language names (ie. LANGS="c m2").
447 The default is to build all languages. Note that grammar
448 files must follow the naming convention of <lang>-exp.y.
449 gdb.lang This holds the current value of the LANGS macro. It is
450 examined every time make is called, and is updated if
452 eval.c Added #ifdef _LANG_<lang> to these files.
453 expread.c Still need to add them to dbxread.c and coffread.c.
461 Mon Jun 24 16:33:11 EDT 1991
463 language.[ch] Added the functions hexformat_pre() and
464 hex_to_string_pre(), which take a prefix argument to
465 include in the format string. Thus, hexformat_pre("08") will
466 return "0x08x" (if the working language is language_c).
467 Made hexformat() and hex_to_string() calls to the above
468 with "" as the prefix argument.
470 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
471 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
472 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
473 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
474 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
475 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
476 valprint.c, vax-pinsn.c
478 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
479 calls to hexformat() and hex_to_string(). Format strings without
480 the leading "0x" were ignored.
482 depend Updated to take the above into account.
485 Tue Jun 25 15:27:18 EDT 1991
487 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
488 and type_check_t to keep track of the current state of
489 range and type checking.
490 main.c Added the variables range_mode, range_check, type_mode,
491 and type_check to record the current state of range and
492 type checking. Added initialization code to main().
493 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
497 Tue Jun 25 17:57:08 EDT 1991
499 dbxread.c process_one_symbol() updates the variable (enum language)
500 source_lang based on the extension of the filename
501 contained in the N_SO sybmol that started this symtab.
502 When end_symtab() is called, the value of source_lang is
503 put into the language field.
504 stack.c select_frame() sets working_lang (and possibly type_check
505 and range_check) to the language field of the symtab
506 associated with the frame that is selected if working_mode
507 is language_auto. If working_mode is language_manual, a
508 warning is printed and working_lang is not set.
509 language.c Added the function set_type_range(), which sets the value of
510 type_check and range_check (if their modes call for
511 automatic setting) based on the current value of
512 working_lang. A non-zero argument will cause the current
513 settings to be output.
516 Wed Jun 26 14:51:40 EDT 1991
518 eval.c Added range checks on assignment.
519 m2-exp.y Added the grammar for sets to the language. Currently,
520 these do not do anything except print an error message.
522 Wed Jun 26 17:01:04 EDT 1991
524 m2-exp.y Added the ability for parse_number() to parse negative
525 numbers. A global flag is set upon encountering a unary
526 minus. This was done to make, for example, 1 parse as a
527 CARDINAL, and not as an integer, per Wirth's examples in
528 Programming in Modula-2 ed.4.
529 valprint.c Added support for "set radix 2" by then setting
530 output_format to 't'.
531 eval.c Implemented range checking on subrange types. Added calls
532 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
533 Implemented MIN and MAX for ennumerated types. The
534 minimum value of an ennumerated type is defined by Wirth
535 as the first identifier, and the maximum as the last.
536 m2-exp.y Made octal numbers ending with "B" be characters and those
537 ending with "C" be numbers, per Wirth's book. (p. 34)
539 Thu Jun 27 14:11:52 EDT 1991
541 stack.c select_frame() now only sets working_lang, it does not
542 notify the user. If working_mode is language_manual, then
543 a warning is issued once.
544 main.c At the end of each call to execute_command(), working_lang
545 is checked against the local static (enum language)
546 current. If they differ and working_mode is
547 language_auto, the new settings of language, type and
548 range checking are printed out.
549 stack.c Modified frame_info() to include the language of the
550 current frame in the output of "info frame".
551 language.[ch] Added the function language_str() which returns the name
552 of the current language.
554 Fri Jun 28 15:33:14 EDT 1991
556 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
557 the language. INCL and DECL currently cause an error,
558 since sets are not implemented yet. INC and DEC are
559 implemented as PREINCREMENT/PREDECREMENT with one
560 argument, and as ASSIGN_MODIFY with two arguments.
561 eval.c Added type checking to the above cases.
562 value.h Added not_lval_constant to the lval_type ennumerated type.
563 not_lval_constant means that the value is a constant
564 value; that is 3 or 'a' or TRUE, not as in a constant
565 identifier. This is used to help coerce numbers such as 3
566 to either signed or unsigned numbers.
567 valops.c Added the function value_coerce_constants() which coerces
568 constant integers as following: if one is a constant and
569 the other is not, the constant's type is set to the type
570 of the other argument. If both are constants and one is
571 signed, the other is converted to a signed constant.
573 Sat Jun 29 17:26:29 EDT 1991
575 valarith.c Added a better range checker. It now checks range
576 (successfully) on integral operations [+-] (signed and
577 unsigned) for any C sized type. Still does not work well
579 int_in_size() returns an integer that is coerced to fit into
580 specified number of bytes.
582 Mon Jul 1 13:04:14 EDT 1991
584 language.[ch] Added the function binop_result_type(), which returns the
585 builtin (struct type *) type that would be the result of a
586 binop on the two values V1 and V2.
588 Wed Jul 3 19:22:53 EDT 1991
590 source.c Extended source_info() to include the source language in
591 the output from "info source".
593 Fri Jul 5 13:48:52 EDT 1991
595 utils.c Moved the support functions for the GDB set/show commands
596 dealing with language into language.c.
597 language.c Added the function language_info(), which displays info
598 about the current working language, type and range check
599 settings. Called via the GDB command "info language".
600 Added an initialization routine _initialize_language(),
601 that sets defaults for the language, type and range
602 variables and sets up the new GDB commands.
603 main.c Language setup moved to language.c.
606 Mon Jul 8 10:10:22 EDT 1991
608 valarith.c Debugged the range checker for arithmetic. Still does not
609 work for multiplication very well.
611 Mon Jul 8 12:40:37 EDT 1991
613 language.[ch] Added the function value_true() which returns non-zero if
614 its argument represents a boolean true value.
615 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
616 check the truth of an expression.
618 Thu Jul 11 12:51:34 EDT 1991
620 language.[ch] Added the predicate structured_type(), which returns
621 non-zero if the argument is a structured type.
622 Added the predicate pointer_type(), which returns non-zero
623 if the argument is a pointer type.
624 eval.c Added the ability to do addition and substraction on
625 pointers and integers. This case simply bypasses the
628 Thu Jul 11 14:41:42 EDT 1991
631 Added the symbol N_DEFD (0x4a) which is a definition
632 module dependency that is used by the GNU Modula-2
633 compiler and the linker. It is not important to GDB,
634 except that [dbx|coff|mips]read.c should ignore these
637 Fri Jul 12 16:07:00 EDT 1991
639 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
640 0 in val_print(). Also added statements to the else part
641 to coerce type (argument to val_print) to a pointer type
642 if it is an "array of unspecified length".
643 valops.c Added the function value_m2_string(), which returns a
644 (value) value which is a constant string, whose type is
645 (ARRAY [0..n] OF CHAR). The length field of the type
646 structure is set to zero, so it will be interpreted as an
647 "array of unspecified length".
648 stack.c Moved the language/frame mismatch check to
649 main.c:execute_command().
650 main.c The working language is recorded each time
651 execute_command() is executed. If working lang has
652 changed during its execution, then the new
653 language/type/range info is printed out for the user. If
654 the working language does not match the language of the
655 frame, a warning is issued.
657 Sat Jul 13 16:16:39 EDT 1991
659 eval.c Moved all the type-checking stuff for operators to
660 language.[ch] language.c. This is so we can keep language-specific
661 stuff (like for what type operators are defined) in
663 language.[ch] Added the function binop_type_check(), which checks to see
664 if its two (value) arguments are type-compatible with its
665 opcode argument. The opcode should represent an operation
666 involving an operator. Also added the macro function
667 unop_type_check, which calls binop_type_check with a
668 NULL second argument.
669 expprint.c Added Modula-2 operators to the op_print_tab, so info
670 expression.h break works correctly. Also added "op_string", which
671 returns the string corresponding to the (enum exp_opcode)
672 opcode that is its argument.
675 Sat Jul 13 18:26:18 EDT 1991
677 coffread.c Added code to record the type of function arguments with
678 each paricular function. Code is very similar to that
680 dbxread.c Moved add_param_to_type() to symtab.c
681 symtab.[ch] Added function add_param_to_type() from dbxread.c
683 *** NOTE: The above additions have not been tested.
685 Mon Jul 15 12:50:47 EDT 1991
687 langauge.[ch] Added the functions type_error and range_error, which work
688 like error() except if the type/range mode is set to
689 *_mode_warn, then they do not do a return_to_top_level(),
690 but merely print a warning.
691 Also changed [set|show]_[type|range]_command() to support
692 the new "warn" feature.
694 Thu Jul 18 17:50:54 EDT 1991
696 mipsread.c Added code to record the type of function arguments with
697 each particular function. Code is very similar to that
700 *** NOTE: The above additions have not been tested.
702 Fri Jul 19 11:19:10 EDT 1991
704 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
705 UMIN_OF_SIZE, which when given a size of a numeric type,
706 return the maximum and minimum value it can hold. UMAX...
707 and UMIN... return the result for unsigned types.
708 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
709 struct types. They call above macros.
710 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
711 avoid a name conlict with the above.
712 c-exp.y Added range checking on numeric constants in
713 parse_number() for completeness.
714 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
715 return 0 if working_lang is not language_c.
717 Thu Aug 8 14:17:22 EDT 1991
721 breakpoint.c Documentation strings of some commands changed to
722 eliminate the references to the C language where
725 Tue Aug 13 15:48:03 EDT 1991
727 m2-exp.y Added qualified identifiers to the grammar. The semantics
728 are slightly different from those of the GDB operator ::
730 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
731 type_exp, where type_exp is any valid type expression.
733 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
734 printcmd.c Modified ptype_command() so it actually parses the input
735 (necessary for type expressions with scope qualifiers).
736 Added the function ptype_eval() which expects an
737 expression composed of one OP_TYPE element.
738 *.[ch] Replaced all occurences of parse_c_expression with
740 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
742 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
744 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
746 Small fixes from Peter Schauer:
748 * infrun.c (child_attach): Lint.
749 * solib.c (find_solib): Handle shared libs version 2.
751 Small fixes from David Wood:
753 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
757 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
758 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
760 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
761 chars_per_line is at maximum (user typed `set width 0'). Fix
762 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
764 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
766 * coredep.c: include ptrace.h where necessary.
767 * mipsread.c(parse_lines): fix unsigned char problem that was
768 messing up line numbers on SGI's and possibly other MIPS based
770 * infrun.c (child_create_inferior): use better test to check
771 return val from setpgrp().
772 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
773 for sgi/irix support.
775 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
777 * mipsread.c (parse_symbol): Put non-static procedures
780 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
782 Patch together `text_start' and `text_end' for 29K port.
784 * exec.c (exec_command): If NEED_TEXT_START_END, define the
785 variables and set them based on the exec file.
786 * am29k-tdep.c: declare text_start.
787 * valops.c (call_function_by_hand): declare text_end.
789 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
790 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
791 because machines that do this will also have to know to
792 set NEED_TEXT_START_END. Besides, it was a redundant way to
794 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
795 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
798 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
800 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
802 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
803 Pass MUNCH_DEFINE to munch whenever we run it.
804 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
805 format string; use 0x%x instead.
806 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
807 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
808 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
809 * inflow.c: Handle `short' process group IDs.
810 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
811 and check for ptrace errors.
812 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
813 (coff_symfile_init): Initialize text_bfd_scnum.
814 (read_coff_symtab): Use it to find the text [and absolute?] sections.
815 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
816 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
817 Merge target arm case with other "easy" cases. Add target
818 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
819 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
821 * minimon.h, remote-adapt.c, remote-mm.c: Add.
822 * munch: Cope with RT/PC putting fns in data segment.
823 Restore ability to override `nm' by specifying MUNCH_NM.
824 * xconfig/rtbsd, xconfig/ultra3: New host systems.
825 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
826 and remote-adapt. Remove encapsulated coff #define's (the
827 support should go in BFD, and gdb shouldn't know or care).
828 * tconfig/a29k-kern: Same, but for remote kernel debugging.
829 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
830 * tm-29k.h: Update BADMAG (though it should go away).
831 Allow the register definitions to be overridden in another
832 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
833 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
834 DUMMY_SAVE_GR96, for handling kernel calling conventions
835 that use GR64+ rather than GR96+.
836 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
837 remote debugging of Ultra3 kernel. Includes tm-29k.h and
838 overrides various things.
840 * remote-mm.c (mm_attach, mm_wait): Handle attach like
841 child_attach does, making a clean stop in the newly attached
845 * coffread.c: Make coffread independent of any particular
846 variant of COFF. Avoid #include-ing any particular one except
847 internalcoff.h. BFD now passes key values for symbol reading
848 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
849 and the symbol masks and shifts); use them.
850 Remove obsolete end_of_text_addr.
852 * exec.c: Remove unused include files.
854 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
856 * Makefile.in (documentation targets): Pass $(M4).
857 Bugfix from eggert@twinsun.com (Paul Eggert).
859 * stack.c (down_silently_command): Check for stack existence.
861 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
863 * Makefile.in (VERSION): Update to 4.0.3.
865 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
867 * core.c (core_file_command): Print frame at coredump with
868 its level number, by calling print_stack_frame.
869 * frame.h: Add selected_frame_level, print_stack_frame.
870 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
871 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
872 Change print_sel_frame and print_selected_frame callers to
875 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
876 * symfile.c (free_named_symtabs): Ditto.
877 * main.c (main): wrap_here needs an arg.
878 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
879 (solib_add): Avoid noise.
880 (solib_create_inferior_hook): Lint.
881 (sharedlibrary_command): Move dont_repeat to here.
882 * utils.c (error): Call wrap_here to force buffered output.
884 Small patches from Peter Schauer:
886 * coffread.c (start_symtab): Free any existing line_vector before
888 (read_coff_symtab): Ditto for type_vector.
890 * source.c (lines_to_list): New variable, replacing function.
891 (all uses): Use as variable.
892 (_initialize_source): Add 'set listsize' and 'show listsize'.
893 * utils.c (lines_to_list): Remove function.
894 * stack.c (print_frame_info): Use as variable.
895 * defs.h (lines_to_list): Remove declaration.
897 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
899 * breakpoint.c (insert_breakpoints): Restore warning about
900 the program might be running in another process, but only for
901 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
902 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
904 * utils.c (error): if error_pre_print is set, print the string
906 * main.c (main, print_gnu_advertisement, print_gdb_version):
907 Reformat legalese so it always prints, but acts as an "I'm here"
908 message while symbols are being read. If any errors occur,
909 print a few newlines to set off the message and start it at the
910 left margin. Remove mention of "help" command, and don't yak
911 about symbol reading.
912 (catch_errors): Error string is now printed first in case of
914 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
915 suggest the "help" command.
917 * Makefile.in (VERSION): Set to 4.0.2.
919 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
921 * .gdbinit: Remove useless "rr" command. Set complaints
922 to 1 for people debugging gdb.
924 * breakpoint.c, remote-vx.c: Reword strings printed by
925 catch_errors callers.
927 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
929 * WHATS.NEW: "history write -> history save". Doc "write on/off".
930 (Fix from kenc@viewlogic.com.)
932 Fix some infrastructure to be able to cope with host and target
933 machines with different sized basic types (ints, ptrs, etc).
934 (Idea from pierre@la.tce.com (Pierre Willard).)
936 * values.c (value_from_longest): Rename from value_from_long.
937 Handle pointer types as well as integers, so that targets with
938 different pointer sizes from the host can be accomodated.
939 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
940 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
941 uses of value_from_long to value_from_longest.
942 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
943 the correct pointer type to value_from_long{est}.
945 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
947 * remote-vx.c: Remove obsolete code for calling functions via
948 vxworks kludge interface (it referenced value_from_long).
950 * valops.c (value_string): Find malloc with lookup_misc_func, not
953 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
955 Make writing to files work properly. (Fixes to BFD are also needed.)
957 * core.c (core_open): Open file ourselves, read or r/w, depending on
958 write_files. Use bfd_fdopenr.
959 * gdbcore.h (write_files): New variable.
960 * exec.c (write_files): Define variable, add set&show for it.
961 (exec_file_command): Use write_files to open for read or r/write.
963 Make shared library reading happen automatically. These changes
964 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
966 * inferior.h (stop_soon_quietly): Add to exported variables.
967 * infrun.c (child_create_inferior): call solib hook, if defined.
968 (child_attach): call solib hook, if defined.
969 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
970 (find_solib): Use lookup_misc_func rather than hand-rolled.
971 (symbol_add_stub): New stub for catch_errors.
972 (solib_add): Avoid output if !from_tty. Catch errors rather
973 than just calling symbol_file_add and bombing.
974 (solib_create_inferior_hook): Interface with the target process
975 to let it read and alloc shared libs, then figure out what it did.
977 * core.c (validate_files): Fix typo, soften warning.
978 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
980 * utils.c (fputs_demangled): Avoid duplicate printing if
981 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
983 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
984 (Fix from pierre@la.tce.com (Pierre Willard).)
986 * main.c (catch_errors): Change argument to a char * from an int,
987 since a char * can point to a struct full of glop, but an int
988 is not guaranteed to be able to hold a pointer.
989 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
990 breakpoint_re_set_one, breakpoint_re_set): Adapt.
991 * core.c (core_open, solib_add_stub): Adapt.
992 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
994 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
996 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
997 by adding .NOEXPORT target.
999 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1003 * Makefile.in (VERSION): Roll to 4.0.
1004 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1006 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1008 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1011 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1014 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1016 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1017 reflect above name change
1019 * WHATS.NEW: correct pointer to refcard.
1021 * doc/gdb.texinfo: update New Features, Installing
1023 * doc/gdbint.texinfo: add short description of configure +template
1025 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1027 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1029 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1031 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1032 tar file, add dependencies for referenced doc files.
1034 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1036 * coffread.c, symfile.c, stack.c: saberized.

1050 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1052 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1053 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1054 breakpoint.c, main.c: lint.
1056 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1058 Install new configuration scheme for GDB and friends.
1060 * config.sub: Translate ordinary names to three-part names.
1061 * configure: Use three-part names internally.
1062 * configure.in: Translate three-part names to filenames.
1064 * README, WHATS.NEW: Update for gdb-4.0.
1065 * Makefile.in: Roll VERSION to 3.99.
1067 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1069 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1070 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1071 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1072 to single structures rather than arrays; when passing
1073 their address, use &. This avoids trouble with bdead compilers.
1074 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1075 instead. This avoids portability headaches.
1076 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1078 * source.c (open_source_file): Avoid ANSI const bdeath by
1079 skipping declaration and then casting result value.
1080 * tm-hp300bsd.h: Clarify comment.
1081 * utils.c (strstr): Result is const char *; ANSI bdeath.
1082 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1083 since system include file defines it differently from "defs.h",
1084 though the two are equivalent for our purposes.
1085 * tconfig/hp300bsd: Add m68k-tdep.o.
1087 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1089 * tconfig/sun*4: Remove warnings about system assembler.
1091 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1093 * mcheck.c: Avoid warning about undeclared abort fn.
1094 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1095 it causes recursive calls to error() when used in cleanups.
1096 To do so requires that we make it a function, so we do.
1097 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1098 * utils.c (do_cleanups): Remove the current cleanup from the
1099 chain *before* calling it, in case error() is called from it.
1100 The result won't be pretty, but won't be an infinite loop either.
1102 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1104 * dbxread.c (read_struct_type): Grok anon structs for C++.
1105 (vb_name, vptr_name): Null terminate these strings.
1107 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1109 Minor bug fixes from BSD Net2 gdb:
1111 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1112 returns 0, there is no previous frame.
1113 * breakpoint.c (commands_command): If !from_tty, don't call
1114 input_from_terminal_p().
1115 * dbxread.c (record_misc_function): Speed up slightly.
1116 (compare_psymbols): Ditto.
1117 * infcmd.c (do_registers_info): Take a second argument to
1118 determine whether to print float registers. "info registers"
1119 does not do so anymore. "info all-registers" does, now.
1120 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1122 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1123 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1127 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1128 executing_breakpoint_commands if we are interrupted by error.
1129 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1130 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1131 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1132 catch_errors() so we can setup the frame regardless of whether
1133 the shared libs work.
1134 * ieee-float.c (double_to_ieee_extended): Get exponent from
1135 right place in little-endian systems. From John Carey.
1137 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1139 * main.c: Remove unused terminating_signals and catch_termination().
1140 (long_options): Terminate with a zero element.
1141 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1142 (gdb_readline): Make call-compatible with readline.
1143 (init_signals): Improve comments re vfork vs. signal.
1145 * utils.c (prompt_for_continue): Use new gdb_readline().
1146 If we prompt for continuation, we don't let CR repeat the previous
1147 command, once we get back to a prompt. It's too easy to keep
1148 hitting CR, expecting "--more--" prompts, and have some long
1149 command start repeating on you.
1151 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1153 * blockframe.c (frameless_look_for_prologue): Speed up by
1154 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1155 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1156 Define two variants, one faster.
1157 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1158 and return zero, rather than giving an error.
1159 (setup_arbitrary_frame): Initialize the PC in the new frame.
1160 (skip_prologue): Add a second arg saying whether we're just
1161 checking for a frameless function or not.
1163 * core.c (core_open, core_close, core_xfer_memory): Move
1164 section table pointers and bfd* into the target_ops.
1165 (core_open): Allow errors in shared lib reading, etc.
1166 (core_files_info): Describe shared library sections.
1168 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1169 exec_files_info, set_section_command): Move section table
1170 pointers and bfd* into the target_ops.
1171 (add_to_section_table): Add BFD to section table.
1173 * target.c (target_xfer_memory, target_info): Pass target to
1174 xfer_memory and target_info functions.
1177 * gdbcore.h: Move struct section_table.
1178 * target.h: New home of struct section_table.
1180 * solib.c (solib_add): New argument is the target_ops whose
1181 section list is to be added to, if any. Reallocate the
1182 sections in that target to add any that come from shared libs.
1183 (throughout) so_sections renamed to sections.
1184 (solib_xfer_memory): Deleted.
1185 * tm-sunos.h (SOLIB_ADD): Add target argument.
1186 (SOLIB_XFER_MEMORY): Delete.
1188 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1189 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1190 from target_ops. It's the same on all targets. Add two section
1191 pointers to target_ops.
1193 * stack.c (find_relative_frame): Dump ancient algorithm for
1194 "down", just use handy "next" pointers.
1195 (frame_command): Don't error if there is no stack; let user
1198 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1199 modifies static state in the parent process; new_tty itself
1200 runs in the child and modifies the child's file descriptors
1201 to match the saved static state.
1202 * infrun.c (child_create_inferior): Call new_tty_prefork,
1205 * infptrace.c (child_xfer_memory): Add ignored target arg.
1206 * remote-eb.c (eb_xfer_inferior_memory): ''
1207 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1208 * remote-vx.c (vx_xfer_memory): ''
1209 * remote.c (remote_xfer_memory): ''. Rename from
1210 remote_xfer_inferior_memory.
1212 * main.c (main): Only try to attach "corefile" argument if
1213 it starts with a digit.
1215 * symfile.c (symbol_reloading): New "set/show" variable.
1216 (symbol_file_add): Shorten message about symbol reading.
1217 (add_symbol_file_command): Merge with add_syms_addr_command,
1218 since this should work on all targets now.
1219 (stop_whining): Default to zero, to shut up complaints
1220 about bad symbol tables on many systems.
1221 (free_named_symtabs): Just exit unless symbol_reloading.
1223 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1224 and add comment explaining shared library screw.
1226 * source.c: #if defined => #ifdef.
1228 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1230 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1232 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1234 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1235 (doc/Makefile knows how to make one for local config)
1237 * Makefile.in: use doc/Makefile for doc targets
1239 * doc/Makefile: GDB documentation now has its own Makefile
1240 doc/refcard.tex: renamed from "gdbrc.tex"
1241 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1242 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1245 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1247 * values.c (baseclass_addr): When reading target memory, use the
1248 length of the basetype, not the upper type. We've only malloc'd
1249 enough space for the basetype, leading to errors in free().
1251 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1252 ends up as a function specially, since we know the actual type of
1253 the pointed-to address. This (somewhat) fixes display of
1254 expressions that include misc_function_vector names. Try `cond 1
1255 !strcmp("a","b")' then `i b'.
1257 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1258 The child can be proceeded from inside wait_for_inferior in
1259 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1260 getting skipped in that case.
1262 * expprint.c (print_subexp): Use filtered output, since the
1263 subroutines we call use it, otherwise the output is horribly
1264 mangled, since output of wrappable stuff comes out late.
1266 * Makefile.in: Bump VERSION to 3.98.1
1268 * infrun.c (child_create_process): Use execlp to find the
1269 shell to exec our target program. This requires some fiddling
1270 with `environ' since there is no execlpe().
1272 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1274 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1275 Minor rearrangement of refcard permits two new make targets--
1276 gdbrc.dvi DVI output for refcard, using CM fonts
1277 gdbrc.ps PostScript refcard, using PS fonts
1279 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1283 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1284 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1286 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1288 * doc/gdb.texinfo: last changes for release.
1289 Minor typo and formatting fixes; incorporated most fixes remaining from
1290 filed mail commenting on earlier drafts.
1292 Added warnings: pipes don't work in run command;
1293 conditions are converse of assertions;
1294 step over fn without debug info goes to next fn;
1295 vars may have "wrong" values near fn entrance, exit
1297 Added example from Kingston on printing repeated nonadjacent values
1299 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1300 shell mode for signals
1302 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1303 doesn't sound so much like its parent "Stopping and Continuing"; also
1304 moved entries on continue to top of section, so they don't get lost.
1306 Improved installation directions in appendix, added manual formatting
1309 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1311 * configure.in: Remove xm.h and tm.h even if we aren't linking
1312 new ones, so "./configure sun4; ./configure none" does the right
1313 thing. Assume that alldeps.mak and depend are already built in
1314 srcdir, and avoid running "make" (particularly "make depend",
1315 which involves "gcc") from inside configure. Build Makefile
1316 directly rather than building Makefile.conf first.
1317 * configure: Regenerate with above changes.
1318 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1319 to 3.98. Revise gdb.tar.Z procedure to produce a file
1320 called gdb-$(VERSION).tar.Z but which unpacks into a
1321 directory called "gdb". Move non-source files out of
1322 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1323 (depend): Don't try to do "gcc expread.y".
1324 (expread.o): Update dependencies by hand.
1326 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1329 Fixed a variety of small typos that prevented info from formatting
1330 cleanly; altered too-long heading for GPL Appendix, as discussed
1331 w/RMS; Changed date on cover to July 91.
1333 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1336 (1) Applied some fixes due to comments from Larry Breed (easier ones
1337 through chapsec 5.2)
1338 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1339 it's broken in latest texinfo
1340 (3) Introduced *some* use of [] for optional arguments, where
1341 explanation is not simpler by listing cmd w arg and cmd w/out arg
1342 separately. Still not using @deffn.
1343 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1344 couple of headings are too long. Need patches to texinfo or revision
1347 * Partial update to README (which still needs work for this
1348 release!): (1) use of configure corrected for new script,
1349 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1351 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1353 * symtab.c (lookup_symbol): Don't complain right off about
1354 no debug symbols; use the misc function vector first.
1355 (list_symbols): Use misc function vector to find symbols
1356 that don't have debug info, and print them.
1357 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1358 PC range doesn't match symtab PC range, as it does on the
1359 MIPS because our symtab reading isn't perfect.
1361 * dbxread.c (dbx_symfile_read): Make warning about
1362 "no debug symbols" slightly nicer.
1364 * source.c (select_source_symtab): If "main" symbol exists,
1365 but decode_line_spec can't find line info, don't just return
1366 a zero; try other source symtabs or give an error.
1368 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1369 their low addresses first, then rip through fixing high addrs.
1371 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1372 <runene@ifi.uio.no>.
1373 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1375 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1377 * Minor, mostly mechanical, cleanup of doc subdir for clean
1378 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1379 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1381 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
1383 Mostly MIPS and general symbol-reading fixups.
1385 * doc/gdbint.texinfo: Add documentation on symbol-reading
1388 * mipsread.c: Remove kludges around #include "ecoff.h".
1389 Remove redefinitions of a_magic, etc, no longer used.
1390 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
1391 Fix global overview comments to match symfile.c protocol.
1392 (mipscoff_new_init): Eliminate cur_hdr if we have one.
1393 (mipscoff_symfile_read): Eliminate unused code. Avoid
1394 sorting all the symtabs, when all we have read here is psymtabs.
1395 The symtabs are sorted as they are created anyway. Tell
1396 condense_misc_bunches whether we're mainline.
1397 (psymtab_to_symtab_1): Pass filename when recursing, to make
1398 stack trace more informative.
1399 (parse_partial_symbols): Assume cur_hdr as argument.
1400 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
1401 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
1402 the TYPE_NAME of char *, since that's done in symfile.c.
1403 (free_numargs, parse_symbol, add_symbol, add_block,
1404 shrink_linetable): Declare these fns void.
1405 (upgrade_type): Convert tree of if's to switch. Clean up
1406 bogus "off == 0" handling with a complaint. Avoid setting
1407 field bitpos and bitsize of array with lower and upper bounds.
1408 Check specified bitsize of elements against their actual type's
1409 bitsize, and complain if different. Complain about unknown
1411 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
1412 (psymtab_to_symtab_1): Print names of subsidiary files that
1413 are being read in. FIXME, we read far too many files. This code
1414 is not the problem, the problem is in parse_fdr where the psymtabs
1416 (cross_ref): Result should indicate that we used one aux entry
1417 normally, or two if we encountered a "next" entry. This used
1418 to leave the caller pointing at the wrong aux entry.
1419 (add_symbol): If overflowed cur_block, reallocate it larger,
1420 chase all pointers to it, and complain(), rather than clobber memory.
1421 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
1422 (new_field): Only allocate one field initially, not two.
1423 Pull ++ out of macro argument. Simplify.
1424 (_initialize_mipsread): Avoid initialization of importd
1425 global_psymbols and static_psymbols.
1427 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
1428 to properly set pst->symtab; avoid searching for it.
1429 (symfile_fns): Improve comments, add a FIXME.
1430 * dbxread.c: Update comments to reflect symfile protocol.
1431 (read_ofile_symtab, end_symtab): Return the symtab.
1432 (psymtab_to_symtab_1): Set pst->symtab.
1434 * coffread.c (coff_symfile_read): tell condense_misc_bunches
1435 whether we're mainline.
1437 * symfile.h (sym_fns): Remove unused sym_discard member.
1438 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
1440 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
1441 the environment variable is not.
1442 * infcmd.c (finish_command): Use filtered printfs.
1443 * cplus-dem.c: Add struct tags to a few unnamed structs.
1444 * valops.c (value_coerce_array): Improve comments.
1445 * valprint.c (type_print_varspec_suffix): Print array size only
1446 if greater than zero.
1447 * m88k-tdep.c: Shift some lines left by one space, that had
1448 apparently been trashed at some point.
1449 * TODO: More things to do, a few got done.
1451 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1453 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
1454 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
1456 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
1457 * expread.y, findvar.c, symmisc.c: Ditto.
1458 * printcmd.c (address_info): Update printed forms of LOC_
1459 symbols. Elim LOC_EXTERNAL.
1460 (print_frame_args): Keep track of param stack offsets before
1461 re-looking up to find the local register param is kept in.
1463 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
1464 Further integration of mipsread into gdb. Eliminate unused
1465 routines, duplicate declarations. Handle static symbols in
1466 psymtabs as well as external symbols. When reading symtabs,
1467 insert symbols into the correct block (global, static, or a local
1469 (read_mips_symtab, parse_partial_symbols): Don't pass useless
1471 (mipscoff_symfile_read): Don't call select_source_symtab.
1472 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
1473 rather than SYMBOL_VALUE.
1474 (parse_external): Comment clobbering of top_stack.
1475 (parse_partial_symbols): Update comments. Allocate and parse
1476 static symbols as well as external symbols. FIXME, enum values
1477 are not handled in this pass, but should be. Inline new_psymbol.
1478 Use SYMBOL_VALUE_ADDRESS.
1479 (psymtab_to_symtab_1): Read symbols into global static block
1480 by default (until enter some function's local block context).
1481 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
1482 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
1484 * source.c (select_source_symtab): Select a source symtab
1485 from either the symtabs or, failing that, the psymtabs.
1486 (list_command): Update error message.
1487 (forward_search_command, reverse_search_command): Use getc, not
1488 fgetc, for speed. FIXME, add comment about buffers that die if
1489 overrun by long line.
1491 * values.c (unpack_field_as_long, modify_field): Avoid shifting
1492 by an entire word, which is not portable, if we have a 32-bit
1493 field. (Code in dbxread.c already turns such bitfields, if
1494 aligned, into ordinary ints, but fixing this will help for other
1495 symbol formats and for future changes.)
1496 * core.c (core_open): Handle ANSI const brain death.
1497 * utils.c (vprintf): Fix varargs typo.
1499 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1501 * findvar.c (find_var_value): Handle &function better.
1502 * TODO: Document work needed on &fn and &array.
1503 * printcmd.c (print_address_symbolic): New arg is the prefix
1504 to print if a name is printed.
1505 (print_address_demangle): Honor "set print address" now.
1506 Use new arg above to improve spacing of output.
1507 * valprint.c (val_print): When printing function pointers,
1508 print symbolic form too.
1509 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
1511 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1513 * core.c (memory_error): Reword error msg to mislead less.
1515 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
1517 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
1518 parse_partial_symbols): Use newer BFD internals (external_filehdr
1519 and external_aouthdr), byte-swap the fields that we care about
1520 before using them, and make the file header data local to
1521 read_the_mips_symtab rather than global.
1523 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
1525 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
1526 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
1528 * main.c (command_line_input): Flush stdout and stderr
1529 before every call to readline. This reportedly fixes a bug
1530 that comes up in Sys V running emacs-gdb and/or xxgdb,
1531 when stdin/out are pipes or sockets.
1533 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1535 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
1536 Avoid declaring Makefile dependencies, because GNU Make stupidly
1537 tries to update it if we do.
1539 * coffread.c: Revise for minor changes to bfd internal coff
1542 * configure: If -template= is given a relative path, make it
1543 absolute before recurring in subdirectories.
1545 * configure, configure.in, Makefile.in: Install "configure" script
1546 as replacement for config.gdb.
1547 * config.gdb, Makefile.dist, Makefile.sdir: Remove
1548 * README: Update for configure, mostly. FIXME.
1550 * Add dec3100 as equivalent to littlemips. Indicate in all host &
1551 target config files that they are for the host. When the lines
1552 get copied into the Makefile, this makes it more obvious what's
1555 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1557 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
1558 tabs, which end up in the disassembler output inadvertently.
1560 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1562 Make it compile cleanly in an ANSI GCC2 environment.
1564 * blockframe.c: <stdio.h>
1565 * cplus-dem.c: free takes a void *, ifdef __STDC__
1566 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
1568 * defs.h (alloca): Avoid doing anything if alloca already def'd.
1569 * stddef.h, stdlib.h: Remove these files.
1570 * symtab.c: Avoid declaring qsort, close.
1571 * symfile.c: Avoid declaring close.
1572 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
1573 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
1575 Assorted other changes.
1576 * dbxread.c: include "libaout.h", not "liba.out.h".
1577 * printcmd.c (print_frame_args): Set recurse properly for
1578 indentation of struct and array parameters.
1579 * valops.c (value_cast): Allow cast to void.
1580 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
1581 single_step() in a target-independent fashion.
1582 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
1583 set up to be ready to continue. This makes us target independent.
1584 * infptrace.c (child_resume): Remove call to single_step; now
1585 can single step a SPARC target of any kind.
1587 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1589 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
1590 docn into separate sections---basically chapters, plus two loose
1591 pieces that can be configured to go in different places. This
1592 allows GNU m4 to preprocess the manual without coredumping.
1594 * Makefile.dist: tell TeX where to find texinfo.
1596 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1598 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
1599 the new target "rdl-apps.texinfo" which captures the Makefile
1600 variable that records where to find the Readline libraries.
1602 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
1604 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
1605 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
1606 * defs.h (const, volatile): Only define if not already defined.
1607 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
1609 * README: Update for release 3.95.
1610 * config.gdb: Don't create readline dir in subdir builds.
1611 * main.c: Include with "..." form for non-system include files,
1612 so "gcc -MM" for "make depend" works.
1613 Include readline files with "...h" rather than <readline/...h>.
1614 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
1616 * coffread.c: Undo minor damage done by Rich Pixley. Use
1617 different internal and external representations of COFF
1618 data structures. Use new BFD routines for swapping them in and
1620 * symfile.c (free_named_symtabs): Avoid freeing file names that
1621 are null or empty. Old i960 tools seem to produce files that
1622 claim to have empty names, causing each successive file read
1623 to blow away the previous one.
1624 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
1625 Move deferred_stores to top of file, but don't separate its
1626 #define's from its variable. Add commentary.
1627 * Makefile.dist: Fix Rich damage; undo "configure" changes in
1628 favor of keeping the (working) config.gdb. Move readline
1631 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
1633 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
1635 * infptrace.c (fetch_registers): no result, since now void.
1636 * tconfig/news: target depends on m68k-tdep too.
1638 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1640 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
1643 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
1644 applied various small fixes due to or inspired by RMS comments
1646 * doc/gdb.texinfo: finished using all RMS comments, save those for
1647 appendices on readline and cmd history (which are in other source
1650 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1652 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
1653 chapter 9; (2) documented 'break' command's menu mode for
1654 overloaded names, in response to hgs problem report C++ p-31
1656 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1658 * doc/gdb.texinfo: (1) better introductory example; (2) more
1659 consistent use of @code, @samp, @file, @kbd throughout; small
1660 cleanups to first three nodes; (3) new "Contributors" node;
1661 (4) Appendix, Renamed Commands; (5) divert specialized startup
1662 instructions to "Targets" chapter for generic manuals, while
1663 leaving them up front for manuals specific to specialized
1664 environments; (6) apply fixes from RMS comments through chapter 4.
1666 * pretex.m4: modify explanatory text slightly (and redefine
1667 "regexp") to keep GNU m4 from complaining. (It still crashes
1668 later, but one step at a time...)
1670 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
1672 * readline/readline.c (update_line): Avoid dereferencing a pointer
1673 before comparing it to its bounds. Saber caught this.
1674 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
1675 and only set PC if tgetstr returned non-null. Saber caught this.
1677 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1679 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
1680 stuff for config manual) here where it counts; updated
1681 to use new subdir structure (gdb/doc/).
1683 * Makefile: generated from above via
1687 * gdbint.texinfo: added instructions on generating gdb.info* files
1688 locally for release. These are ordinary info
1689 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
1690 Makefile)---but due to use of texinfo 2, can't count on makeinfo
1691 to generate these, so we distribute them already formatted.
1693 * gdb.texinfo: included full Info node and menu crud (as generated
1694 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
1696 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
1697 put in comments-for-future gdb.info target (one day makeinfo will
1700 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1702 * gdb.texinfo: Updated to include new or old undocumented
1703 commands, at least the following (perhaps some others I forgot to
1704 record): info f, info float, info path, info program, info s, info
1705 set, info source, info terminal, info types, info user, set/show
1707 Also covered all recent GDB command renames for v4.
1709 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1711 * mipsread.c: Rather than keeping count of how many symtabs
1712 and psymtabs we have, for sorting purposes, count them when
1713 we need to sort. This fixes bug in rereading of symbol tables.
1715 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1717 * infcmd.c: renamed "info path" to "show paths"

1732 symtab.h, target.c, target.h: Lint.
1733 * core.c: setup and select frame after reading shared libs,
1734 else reading shared libs will clobber them. Lint.
1735 * utils.c (error): Force out any buffered wrap text.
1737 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1739 * remote.c: Remove decls of memory_insert_breakpoint
1740 and memory_remove_breakpoint, no longer used. (Suggestion of
1743 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
1744 to make it easier to interface to "configure"'d libraries.
1746 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
1748 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
1749 aliases for set/show print.

1838 * infptrace.c (PT_WRITE_D, PT_READ_D): Use correct values.
1839 (This still doesn't seem to make MIPS bkpts work.)

1875 : Lint. Use read_memory not read_memory_integer on CORE_ADDR's.
1876 Use {value_as,unpack}_pointer (added to values.c)
1877 not {value_as,unpack}_long on CORE_ADDR's.
1878 Use longest_to_int (added to defs.h) instead of cast to int.
1879 Remove from_tty arg to mod_path.
1880 Put symfile_bfd in {coff,dbx}read.c not symfile.h.
1881 Use OP_NULL instead of 0 where dummy enum exp_opcode needed.

1956 rather than smash_to_method_type.
1957 symtab.c, symtab.h (allocate_stub_method): New function.
1958 dbxread.c (read_type): If we get "##", don't lookup_function_type
1959 and start clobbering it; allocate_stub_method instead.
1960 * printcmd.c (x_command): Dereference references.
1961 * valprint.c (type_print_varspec_prefix, case TYPE_CODE_METHOD):
1962 Don't print " " type_print_base (...) "::" if !passed_a_ptr.

2300 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
2301 to the main file, as well as to include files. Also, put global
2302 functions into the global psymtab, to make "i fun" work.
2303 (end_psymtab): Free named symtabs and psymtabs for a file, once a
2304 new psymtab for it has been read.
2305 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
2306 a file, once a new symtab has been read for it.
2307 * mipsread.c: FIXME. We need to do the same for MIPS, but it

2309 queued to the psymtab list.
2311 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
2312 If we have wiped out any old symbol tables, clean up at end of

2328 static psymbols list.
2329 (types_info): Restore this function from its untimely #if 0.

2351 is the first symbol read, even if not mainline.
2352 (dbx_psymtab_to_symtab): symfile might be zero, cope.
2353 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
2354 (set_section_command): New command ("section xxx yyy" -- should
2355 be renamed to "set section xxx yyy" FIXME) which sets the
2356 base address of a section of the exec file, overriding the
2357 virtual address that BFD reports.
2359 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2361 * exec.c: Add add_syms_addr_command to exec_ops, so you can

2366 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
2367 for printing the float info is host-dependent, not
2368 target-dependent. FIXME.
2369 * i386-pinsn.c: Move #includes to top, remove useless ones.
2370 * i386-tdep.c: Don't bother including <.../reg.h> since we
2371 don't use it (and it doesn't exist on host systems).
2373 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
2374 Convert negative numbers properly.
2375 (ieee_test): Make numbers really random; fix format arg.
2377 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
2378 * core.c (core_detach): Unpush core_ops, which might not be on
2379 top. We used to just pop the top, which broke things. Don't
2380 need dont_repeat() any more.
2381 (core_file_command): Psst! Don't repeat it.
2382 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
2383 * expprint.c (print_subexp): Avoid switch fallthru on
2384 BINOP_ASSIGN_MODIFY, so we can print += and such.
2385 * frame.h: Fix typo.
2386 * inflow.c (kill_command): After killing inferior, print our
2387 current frame in the core file, if we have one.
2388 (generic_mourn_inferior): When inferior dies, either select
2389 the current frame (in the new target, e.g. core file), or
2390 set both the current and selected frames to NULL.
2392 Changes from Peter Schauer.
2394 * infptrace.c: Avoid <sys/ptrace.h> on USG.
2396 * Make all file names fit in 14 characters (sigh and damn!):
2397 mv hp300hpux-xdep.c hp300ux-xdep.c
2398 mv symmetry-xdep.c symm-xdep.c
2399 mv symmetry-tdep.c symm-tdep.c
2400 mv convex-opcode.h convx-opcode.h
2401 mv tm-vxworks960.h tm-vx960.h

2404 mv gdb-int.texinfo gdbint.texinfo
2405 mv remote-sa.m68k.shar rem-m68k.shar
2406 mv remote-multi.shar rem-multi.shar
2407 * Makefile.dist, README, config.gdb, convex-pinsn.c,
2408 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
2409 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
2412 * command.c (user_info_1, user_info): New command for listing
2413 the user-defined commands.
2415 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2417 * dbxread.c (really_free_pendings): Clear file_symbols
2418 and global_symbols after freeing them; otherwise, running
2419 this function twice (if it appears twice on the cleanup
2420 chain), we try to free things twice.
2422 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
2423 based on text_addr (the address of text in core), not on addr (the
2424 offset between text in the .o file and in core). This change
2425 is from Peter Schauer.
2427 * main.c: Define ALL_CLEANUPS as a cast of zero.
2428 (return_to_top_level): Use it.
2429 (main): Do all cleanups after each command run as part
2430 of the gdb startup sequence. Also do all cleanups before
2431 entering the command loop, and every time we exit the command
2432 loop and reenter. Before, the cleanups from the startup sequence
2433 were being left undone until the first error!
2434 (command_loop): Rename do_nothing cleanup to command_loop_marker
2435 so we can see it easily when examining the cleanup chain.
2436 (init_signals): Add another do_nothing for signal handling.
2437 (quit_command): Only try to kill target if it has execution.
2438 Problems in the target stack got us into a state where
2439 inferior_pid was nonzero but none of the targets had execution.
2440 In this state you couldn't exit gdb.
2442 * dbxread.c: Two changes from Peter Schauer.
2443 (echo_command): Fflush output after an echo command.
2444 (show_history): Pass all args to cmd_show_list.
2446 * utils.c (init_malloc): Call mtrace to turn on tracing
2447 if the environment variable MALLOC_TRACE is set to a file name.
2448 * mtrace.c: Add source file which provides a log of every malloc,
2449 free, and realloc to a trace file.
2450 * mtrace.awk: Add source file which analyzes the trace file.
2451 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
2452 (VERSION): Roll to 3.94.3.
2454 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
2455 (check_duplicates): Don't bother with watchpoints.
2456 (set_raw_breakpoint): Comment about danger of this routine.
2457 (watch_command): Parse and eval all args before calling
2460 * solib.c (find_solib): Avoid error in referencing memory to
2461 see if any more shared libraries have been added. This is
2462 particularly useful if the target has terminated. Bug reported
2465 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
2466 in bringing up 3.94.2 on the Sun-3.
2468 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
2469 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
2470 expression (in scope) before reenabling watchpoint.
2471 * signame.c (init_sigs): Add missing declaration of i, fix
2472 sys_siglist declaration.
2473 * source.c (list_command): Fixed range computation to use
2475 * stack.c (backtrace_command): Do not allow command if target has
2476 no stack, print informative error message.
2477 * target.c (target_command): Do not write into command line
2478 because this fails if the target command is used in a user defined
2479 command. [This change was enhanced by gnu to support any-
2480 unique-prefix matching on target names.]
2481 * valops.c (value_struct_elt): Avoid infinite loop on an
2482 erroneous attempt to print the member of function (try p main.p).
2484 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2486 * expread.y (name_no_typename): Avoid reduce/reduce errors
2487 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
2488 Since the GDB parser really doesn't use name_no_typename in a
2489 name-only context, the parser can't tell the diff between
2490 names and numbers here. Avoid allowing a name_no_typename
2491 to be a NAME_OR_*INT to resolve the conflict.
2493 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2495 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
2497 * valprint.c (val_print_fields): bitfield printing didn't handle
2498 byte order. Indirect through a few more fns to cope.
2500 * values.c (modify_field): also cope with byte order.
2502 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2504 Cleanup for release 3.94.2:
2506 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
2507 include files. Roll version to 3.94.2.
2509 * coffread.c (init_stringtab): Read length into unsigned char
2510 array before swapping; don't assume 32-bit longs.
2512 * target.c (target_info): Don't bother with get_sym_file, just use
2513 the symfile global variable.
2514 * symtab.h, symfile.c (get_sym_file): Delete it.
2516 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
2517 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
2518 (read_type): Replace one more error() with complain().
2520 * mipsread.c (parse_partial_symbols): Replace printf with complain.
2522 * i960-tdep.c: Fix copyright attribution.
2524 * config.gdb: Quote all backquotes in doublequotes. You can
2525 quote me on that. BSD 4.4 shell found this one.
2527 * infptrace.c (throughout): The third argument to ptrace is an
2530 * infrun.c (wait_for_inferior): When program has terminated, we
2531 have to call target_terminal_ours before we pop that target off
2532 the stack (e.g. before a call to target_kill or
2533 target_mourn_inferior). This fixes problem where a program
2534 terminates, then GDB stops for (tty output) and you have to type
2535 "fg" to the shell to resume it. FIXME: This code for what to
2536 do after termination really should be in normal_stop instead.
2538 * gdbcore.h (read_memory_check): Change declaration; it changed
2541 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
2542 4.4 prereleases, this avoids a bug in their sgtty compatability
2544 * remote.c: Use terminal.h rather than hand-rolling the same.
2546 * signame.c, signame.h (psignal): Arg is unsigned, not int.
2547 * utils.c (strsave, strstr): Fix arg types.
2548 * valprint.c (val_print): lint
2550 MIPS symbol table support from Per Bothner:
2552 * symfile.c (symtab_fns): Remove initializer table that needs to
2553 be hacked for each new symbol file format supported.
2554 (add_symtab_fns): New function, chains symbol table
2555 handlers into the global list.
2556 (symfile_init): Search this list.
2557 * symfile.h: Add next pointer, declare add_symtab_fns.
2558 * coffread.c (_initialize_coffread): Call add_symtab_fns.
2559 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
2561 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
2562 symbol *). Thus, we no longer need the hack to trash
2563 pst->filename. Good, since that hack confused code in symfile.c!
2565 (reorder_symtabs, destroy_all_symtabs): Removed static
2566 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
2567 Instead, the latter now uses a temporary array (stack-allocated
2568 from an obstack, and then freed).
2570 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
2571 haven't been set in the outermost stBlock of a procedure. This was
2572 a problem with f77 binaries on Ultrix 4.?.
2574 (new_symtab, new_symbol, new_type): Continue changing code to use
2575 obstacks more and otherwise conform to dbxread internal style.
2576 Made the free_code of symtabs be free_linetable (as in dbxread)
2577 instead of free_contents. This implies memory leaks when reading
2578 a new symbol table, until the conversion is finished. Did change
2579 (struct symbol) and (struct type) to be allocated on the
2580 symbol_obstack. Blocks and blockvectors are among the things
2583 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
2584 tested much, but it solved one problem (reported by Meissner), and
2585 cleans up some other things. The problem happened when an
2586 included file contains actual code (functions) and not just
2587 definitions. The mips coff is a little inconvenient there, since
2588 it may cause a procedure to be mapped to the wrong psymtab.
2590 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
2591 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
2592 this will need work for the new core paradigm.
2594 Opcode patches from the net:
2596 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
2597 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
2598 missing altogether - they are added here. From Bruce Bauman.
2599 * mips-opcode.h: The low mask for C0 instructions was too small.
2600 From Garrett Lau. I modified the fix to check the entire 32-bit
2603 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
2606 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2608 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
2610 * dbxread.c (read_type): Pointer subtraction (value_sub in
2611 valarith.c) sometimes failed because the types of the
2612 pointers being subtracted were not identical.
2613 These differed because dbxread.c was allocating pointer types
2614 using dbx_alloc_type+smash_to_pointer_type instead of
2615 lookup_pointer_type. I failed to find a justification for the
2616 former, so I changed it to use the latter. Similarly, I
2617 replaced smash_to_function_type by lookup_function_type,
2618 and smash_to_reference_type by lookup_reference_type.
2620 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
2621 _initialize_mipsread): corresponding changes.
2623 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
2625 * source.c (mod_path): Do tilde_expand on each component of the path,
2626 rather than on the (list of) paths as a whole.
2627 (print_source_lines): Set first_line_listed in addition to
2628 current_source_symtab and current_source_line. If the source was
2629 not findable, after a "dir" command to fix the problem,
2630 a "list" would get the wrong lines.
2632 While I was there... (gnu):
2634 * dbxread.c (read_type): Change error to complaint.
2636 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2638 First attempt at detailed understanding of symbol table memory alloc.
2640 * dbxread.c (dbx_symfile_read): Free our string table if we
2641 aren't the mainline. Free the "info" struct since we're done with
2643 (init_psymbol_list): Free any previously allocated psymbol lists.
2644 (): FIXME: Should realloc-down the psymbol lists when done reading
2645 the main symbol file?
2647 * symmisc.c (free_symtab): Free fullname field too.
2649 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
2650 (REGISTER_ADDR): Make result type unsigned int.
2652 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
2653 define REGEX must also define REGEX1 (its dependency).
2655 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2657 * tconfig/i960: No longer works, points you at vxworks960 or
2660 * xgdb.c, XGDB-README: Remove file. Users can get the much
2662 * Makefile.dist: Remove all trace of xgdb.
2664 * breakpoint.c (breakpoint_1): Pass demangle arg to
2665 print_address_symbolic.
2666 (clear_breakpoints): Remove unused function.
2667 (breakpoint_re_set_one): Guts of breakpoint_re_set.
2668 (breakpoint_re_set): Use catch_errors to do them all anyway.
2670 * gdb-int.texinfo (Host versus Target): Add section on what is
2671 a "host" feature versus what is a "target" feature.
2673 * infcmd.c (path_command, path_info): Handle the PATH variable
2674 (object search path) as conveniently as the source search path.
2675 * environ.c (set_in_environ): Set some vars in GDB's environment,
2676 in addition to the child's. PATH, G960BASE, G960BIN for starters.
2677 * source.c (mod_path): New function, from guts of
2678 directory_command, modifies a path. Used by path_command.
2679 (directory_command): Call it.
2680 * defs.h (strsave): Declare.
2682 * utils.c (sevenbit_strings): Add new printing option.
2683 (printchar): Use it.
2684 (strsave): Provide this handy helper routine.
2685 (set_width_command): Rename set_screen_width_command.
2686 (_initialize_utils): "set screen-width" => "set width";
2687 "set screen-height" => "set height"; add sevenbit-strings.
2689 * infcmd.c (do_registers_info): Print floating point registers
2690 in raw hex as well as float format, regardless of whether it is
2691 a "virtual" convertible register.
2692 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
2693 regs as a double, just in case it's being used that way.
2694 * values.c (unpack_long): Comment on array/function coercion.
2695 (unpack_double): Argument is in target byte order now. For
2696 integer arguments, just call unpack_long and float the result.
2697 * m68k-tdep.c: include defs.h for "const" handling.
2698 * remote-nindy.c: Use ieee-float stuff.
2699 (nindy_fetch_registers): Unpack double regs to host double, then
2701 (nindy_store_registers): Pack extendeds to host double, flip
2702 around by misusing unpack_double, send as target double.
2704 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
2705 zero, as when stopped at the first instruction of a process.
2707 * blockframe.c: Fix filename in comment (param.h => tm.h).
2708 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
2709 * tm-68k.h: Fix typos.
2711 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
2713 Changes from a bringup on the DEC Vax under Ultrix 4.0.
2715 * coredep.c (fetch_core_registers): Pass end-address of register
2716 section to register_addr as expected. Don't call supply_register
2717 if we'd just pass it garbage.
2719 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
2721 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
2723 * target.c (push_target, target_info): Cast enums to int for < or
2726 * stack.c (print_frame_info): Identify source file & line
2727 even if we can't print it.
2729 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
2731 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
2733 Clean up IEEE floating point support.
2735 * ieee-float.h: New file.
2736 * ieee-float.c: Write real routines to convert between host
2737 doubles and various target IEEE extendeds.
2738 * m68k-xdep.c: Eliminate assembler code for extended floats.
2739 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
2740 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
2741 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
2742 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
2743 double_to_ieee_extended.
2744 * i960-tdep.c: Define ext_format_i960.
2745 * m68k-tdep.c: Define ext_format_68881.
2746 * sparc-tdep.c: Define ext_format_sparc, though unused.
2747 * Makefile.dist (HFILES): Add ieee-float.h.
2748 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
2751 Obsolete the "coffstrip" program in favor of using BFD's strip.
2753 * nindy-share/coffstrip.c: Remove file.
2754 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
2755 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
2756 * tconfig/nindy960: Remove reference to coffstrip.o.
2758 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
2760 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2762 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
2763 * dbxread.c: Remove static symfile_bfd.
2764 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
2766 * inftarg.c (child_detach): Pop the child_ops vector if the
2767 detach is successful.
2768 * remote-nindy.c (nindy_create_inferior): Don't push a new
2769 nindy_ops since nindy uses the same one for execution and memory
2771 * core.c (core_ops): Use child_attach and child_create_inferior
2772 rather than default attach and create_inferior functions.
2774 Handle floating point registers in core files.
2776 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
2777 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
2778 This version untested since BFD doesn't yet support sun3 core
2780 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
2781 conventions. Fix comments and style. This version has not
2782 been compiled yet, since we have no HP inhouse.
2783 * core.c (get_core_registers): Look for two sections, ".reg"
2784 and ".reg2", and pass both to fetch_core_registers sequentially.
2786 Revise directory path yet again.
2788 * source.c (forget_cached_source_info): Not static any more.
2789 (init_source_path): New default source path is "$cdir:$cwd".
2790 (dir_command): Handle variable arguments ($cdir, $cwd).
2791 (source_info): Print "Compilation directory" rather than
2792 "Originally compiled in" to remind people of $cdir.
2793 (openp): If the path contains $cwd, use current directory.
2794 (open_source_file): If compilation directory is known, replace
2795 first $cdir in path with the compilation directory.
2796 (print_source_lines): Even if we can't print the lines, set the
2797 current symtab and line for future commands like "info source" or
2798 "breakpoint". Also, error message now contains the file name,
2799 line number, and file access error message.
2800 (_initialize_source): Fix help text to describe changes.
2801 * main.c (cd_command): Forget cached source info when we chdir.
2802 * utils.c (strstr): Add simple implementation.
2804 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
2806 * coffread.c (read_one_sym, init_linetable, init_stringtab):
2807 Byte-swap COFF symbol tables if necessary when reading them in.
2808 Use complain() to replace error message in one spot. Needs
2809 corresponding change in bfd/coff-code.h to make some symbol
2810 swapping routines non-static.
2812 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
2814 Merge changes from Eirik Fuller, for UTek.
2816 * defs.h (errno): Add declaration.
2817 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
2818 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
2819 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
2820 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
2821 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
2822 declarations of errno.
2824 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
2826 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
2827 <rpc/rpc.h> and <rpc/types.h>.
2829 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
2831 * i960-tdep.c (examine_prologue): Add new argument limit,
2832 which stops the scan at the end of the prologue, or at the PC.
2833 This fixes a problem where it walks down into the code for the
2834 user's statements if that code looks like function prologues.
2835 Mark Fox and I have been bouncing this code back and forth, making
2836 small changes to it. Callers changed to match.
2838 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
2840 Cleanup for gdb-3.94 release final:
2842 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
2843 the .c files from vx-share and nindy-share, from the various
2844 macros, since they are not found via ALLDEPFILES.
2845 (SFILES): Add tm-i960.h.
2846 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
2847 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
2849 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
2850 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
2852 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
2854 * am29k-tdep.c: Add contribution line.
2855 (examine_prologue): Cache information about function prologues in
2856 the misc-function-vector to avoid lots of references over the
2857 serial line while examining instructions.
2859 * core.c (core_close): New function made from cleanup_core.
2861 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2862 remote-vx.c, remote.c, target.c, target.h,
2863 Update target_ops vector to add attach, close, and load entries.
2864 Use add_syms_addr_command, not add_file_addr_command, for
2865 add_file. Break out close routine from existing code.
2867 * dbxread.c (really_free_pendings): Don't free pending_blocks;
2868 they are in an obstack.
2869 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
2871 (define_symbol): Add symbol type parameter; change callers;
2872 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
2873 it to influence the symbol class on the i960.
2874 (define_symbol): Swap LOC_CONST's into target byte order.
2876 * exec.c (exec_close): New function.
2877 (exec_file_command): Call it.
2879 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
2880 Fix byte order of frame pointer.
2881 (read_var_value): Result of 0 if var's value can't be found,
2882 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
2883 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
2884 (locate_var_value): Use read_var_value and use its lazy address
2885 as the location of the var's value. Lint.
2887 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
2890 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
2891 obsolete Intel versions in favor of vxgdb versions.
2892 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
2893 code dealing with byte order of values, which Intel did in host byte
2894 order rather than gdb-4's target byte order.
2895 (i960_frame_chain_valid): Move to nindy-tdep.c.
2896 (examine_prologue, skip_prologue, frame_find_saved_regs,
2897 frame_args_address, leafproc_return, saved_pc_after_call,
2898 pop_frame): Add vxgdb versions from Mark Fox.
2899 (examine_prologue, frame_struct_result_address): Add code
2900 to deal with the saved value of G13 (struct return address
2902 (frame_args_address): Modify Mark's version to prefer the
2903 saved value over the current value in the topmost frame.
2904 Cache result in the frame info to avoid performance hair in
2906 (print_fault): Add gdb960 code for printing faults.
2907 (_initialize_i960): Actually call check_host.
2909 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
2910 add stub routines. FIXME, these currently just return zero!
2912 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
2913 (attach_command): Call target_attach, not target_open, now.
2915 * infrun.c (normal_stop): Make global, not static, for vx_attach.
2916 (child_attach): Rename from child_open.
2917 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
2918 don't confuse it with a zero step_resume_break_address.
2920 * inftarg.c (child_detach): Eliminate inferior_pid test.
2921 (child_files_info): Clean up message a bit.
2922 (child_ops): Use child_attach, not child_open, to attach.
2924 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
2925 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
2926 findvar.c to here, since it depends on the contents of the
2927 shadow_contents of breakpoints, but keep if #if 0 since it is
2930 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
2933 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
2934 (ptype_command, display_command): Eliminate have_inferior_p and
2935 have_core_file_p in favor of target_has_stack or
2936 target_has_execution.
2937 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
2938 code for actually finding the values of arguments, though we still
2939 keep track of the maximum stack offset for use in printing unnamed
2940 arguments. Handle missing FRAME_ARGS_ADDRESS.
2942 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
2943 (struct nindy_regs): Define registers passed to/from nindy.
2944 (nindy_fetch_registers, nindy_store-registers): Translate between
2945 nindy and GDB formats for the registers.
2946 (dcache_init): Statically allocate the cache, since it was being
2947 allocated by a malloc that was never freed anyway.
2948 (nindy_create_inferior): Error, not core dump, if no exec file.
2949 (nindy_before_main_loop): Use target_load, not target_add_file.
2951 * remote-vx.c (net_load): Specify large timeout for load
2952 requests. Allow user to break out with INTERRUPT.
2953 (net_break): Remove useless code, clean up. Change callers.
2954 (parse-args, skip_white_space, find_white_space): Clean up arg
2955 parsing to cope with quoted strings.
2956 (net_wait, net_quit): Never call error, just return status.
2957 (vx_read_register, vx_write_register): Cleanup status checking.
2958 #ifdef the code based on which CPU we are using (960 or 68k),
2959 FIXME, this should be completely general but it isn't yet.
2960 (vx_xfer_memory, vx_resume): Cleanup status checking.
2961 (vx_run_files_info): Improve message.
2962 (vx_load_command): Renamed from vx_add_file_command. Allow load
2964 (net_ptrace): Remove unused routine.
2965 (vx_wait): Adopt code from vxgdb960 to cope with broken
2966 connections to target machine and prompt to disconnect. Remove
2967 debug printouts. Map some EVENT_'s to SIGnals.
2968 (add_symbol_stub, vx_open): Print names of object files we found,
2969 and "ok" if we read their symbols OK. Clarify output in general.
2970 (vx_attach, vx_detach, vx_kill): Add these commands.
2971 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
2972 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
2973 "info files" output, and create_inferior, since we already have
2976 * stack.c (frame_info): Replace Frame_unknown with 0.
2977 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
2978 (return_command): Pop until the PC matches as well as the FP,
2979 so it works even if the FP is shared with another function,
2980 as in "frameless" or "leaf" procedures.
2982 * symfile.c (load_command): renamed from add_file_target_command.
2983 (add_syms_addr_command): renamed from add_file_addr_command.
2984 (add_syms_command): Stub to call target_add_syms.
2985 (_initialize_symfile): Change command names and descriptions,
2986 add-file => add-syms, and load from alias to its own command.
2988 * target.c (kill_or_be_killed, maybe_kill_then_attach,
2989 maybe_kill_then_create_inferior): Default for attempts to start
2990 a process, if one is already running, is to ask about killing
2991 it and retry if yes.
2992 (upstack_create_inferior): #if-0 it, strata obsolete it.
2993 (push_target, unpush_target, pop_target): to_close() a target
2994 before unstacking it.
2995 (target_info): Renamed from target_files_info.
2996 (_initialize_targets): Rename "i files" as "i target", accessible
2999 * target.h: Improve comments about the target_ vectored routines.
3001 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3002 Convert commenting style to standard GNU style.
3003 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3004 (SKIP_PROLOGUE): No longer a no-op.
3005 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3006 (*_REGNUM): Sort register numbers.
3007 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3008 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3009 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3010 are now 10 byte extendeds, not 8 byte doubles.
3011 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3012 for nindy versus vxworks targets. FIXME, this should possibly go
3013 in the target vector.
3014 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3015 frame_saved_regs and arg pointer with each frame.
3016 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3017 (FRAME_ARGS_ADDRESS): Use cached result.
3018 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3019 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3020 (PRINT_RAMDON_SIGNAL): Call print_fault.
3021 (POP_FRAME): Now works.
3023 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3024 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3025 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3026 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3029 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3030 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3032 * valarith.c (value_subscripted_rvalue): Avoid handling
3033 floats and doubles specially; it gave alignment errors. Lint.
3035 * valops.c (value_of_variable, value_of_this): Error if unknown
3038 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3039 to avoid alignment problems.
3040 (value_print): Handle unknown value address.
3041 (cplus_val_print): Two args are ignored; remove them. Change caller.
3042 (val_print): Use unpack_long rather than pointer-deref.
3045 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3046 to avoid alignment problems.
3047 (value_being_returned): Error if return value unknown.
3048 (set_return_value): Add bogosity warning, FIXME. *
3050 * TODO: A woman's work is never done.
3052 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3053 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3054 Add ieee-float.o to OBS.
3055 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3056 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3057 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3059 Changes to generalize the VxWorks RPC protocol slightly, to handle
3060 i960 as well as 68000.
3062 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3063 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3064 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3065 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3066 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3067 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3068 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3069 so they will move in target byte order rather than network
3070 byte order (happens to be the same).
3072 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3074 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3076 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3079 Add contribution lines to various files, showing where they
3082 * breakpoint.c (break_insn, check_break_insn_size,
3083 read_memory_nobpt): Remove to mem-break.c.
3085 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3088 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3089 entry has bad register number. This change is not
3090 tested in this release, FIXME.
3092 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3095 * value.h: Force value's contents field to be aligned to hold
3096 at least a double or a long long (if supported). This avoids
3097 doing bcopy's in and out of the contents field.
3099 (step_1): Avoid coredump under obscure circumstances when we
3102 * symtab.h (misc_info): Add field to misc function vector for
3103 any kind of cached information the target code desires. AMD
3104 29000 uses this to avoid repeating examine_function_prologue's.
3106 * coffread.c: Lint. Remove static symfile, read_section_header.
3107 core.c (have_core_file_p): Lint: remove.
3108 expprint.c (print_subexp): Lint.
3109 infptrace.c, valops.c, valprint.c: lint.
3111 Roll in changes from vxgdb-5.0.1:
3113 * symtab.h: Comment byte order of each address class. Add
3114 LOC_LOCAL_ARG for frame-relative args (960).
3115 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3116 symtab.c, symmisc.c: ditto.
3118 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3120 * remote.c (remote_resume): Error if resume with a signal.
3122 * symfile.c (prim_record_misc_function): Clear misc_info.
3123 (fill_in_vptr_fieldno): Check stub type of arg.
3125 * valops.c (value_cast): Avoid looking up names of types whose
3126 name we don't know, to prevent coredump. Sun CC produces typedef
3127 rtx and the name of *rtx is zero...
3129 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3131 Roll in changes from final AMD 29000 port (Tiemann).
3133 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3134 for ../include/a.out.encap.h. This might not work now that BFD
3135 is separately compiled. Instead, BFD support for encap will have
3136 to translate machine type 29k into the right COFF_MAGIC.
3138 * infcmd.c: Remove references to inferior_pid that aren't used
3139 in actual ptrace calls; use target_has_execution, etc.
3140 (have_inferior_p): Remove function.
3141 (program_info): Print target info rather than "process number";
3142 avoid gratuitous messages unless from_tty.
3143 (run_stack_dummy, finish_command): Set proceed_to_finish.
3144 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3145 main.c: Lint. Lose have_inferior_p().
3146 inferior.h (have_inferior_p): Remove, lint.
3147 (proceed_to_finish): Add flag to ask that all regs be saved
3148 by normal_stop, for the few commands that need it, speeding up
3149 serial I/O. Add comments to stop_registers.
3151 * remote-eb.c: Remove newline from breakpoint message we grep
3152 for. Never time out when running the user program.
3156 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3158 Roll in changes from vxgdb-5.0.1:
3160 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3161 symbol in its raw form, we are processing an unlinked ".o" file.
3162 See if the target environment has assigned it an address, using
3163 target_lookup_symbol (VxWorks does), and enter it into the symtab
3166 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3167 68k versions for a simpler version that assumes zero FP at bottom.
3168 Fixes bug of truncated stack reports.
3170 * target.h (target_lookup_symbol): Define this routine's args
3171 and result, finally.
3173 * target.c (nosymbol): Default routine for target_lookup_symbol.
3174 (target_default): Default lookup_symbol and call_function too.
3175 (files_info): Only print has_all_memory warning if a non-dummy
3178 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3179 vx_convert_from_virtual): If target does not have floating point,
3180 zero register "values", and avoid doing cross-net conversions.
3181 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3182 (vx_open): Rearrange code that attaches to target and reads
3183 symbols for all loaded modules, to work if some of the modules
3184 are not accessible. Add symbol_stub() and add_symbol_stub()
3185 as callbacks from catch_errors(). Allow connect attempt to be
3186 interrupted painlessly with ^C (FIXME, there are still some bugs
3187 if the interrupt happens during symbol reading.). Print
3188 final message with puts_filtered, since symbol messages are
3193 * main.c (catch_errors): Only print errstring if non-null.
3194 (command_loop): Avoid an ioctl per command to test ISATTY.
3196 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3197 (vx_xfer_memory): Return correct result!
3198 (vx_files_info): Indicate whether target has float or not.
3199 (vx_lookup_symbol): Complain, not error, if target gone.
3200 (vx_open): Print "Connected" msg before disabling immediate-quit.
3201 [FIXME: lookup_symbol and vx_open changes need testing.]
3203 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3204 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3205 contributor lines and update copyrights to 1991.
3207 Changes from an attempted H-PUX host port:
3209 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3210 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3211 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3212 * remote-vx.c: include <sys/time.h> for HPUX.
3213 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3214 "core_file_command" routine to BFD regime. May not work yet.
3216 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3218 * xgdb.c: Replace X10 version with some VJ version.
3219 (FIXME: Its copyright assignment is not on record.)
3220 * xgdb.c: Update include files to X11R4 (Xaw crud).
3221 (xgdb_display_source, create_text_widget): fix call to
3222 get_filename_and_charpos. Rewack source window stuff for X11R4
3223 (gleaned from include files, and "nm's" of binary libraries, since
3224 I had no doc available).
3225 (append_selection, append_selection_word): Disable with FIXME
3226 since R4 changed interface here.
3227 (create_buttons): Add back the old set of buttons.
3228 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3230 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3231 Roll VERSION to 3.94 (not yet final though).
3233 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3235 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3236 obstack_int_grow, obstack_int_grow_fast): Eliminate
3237 cast on left of assignment, which gives MIPS cc fits and is
3240 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3241 F_ALIAS. Use printf, not fprintf, when not passing a file
3243 (compare_opcodes): Check that identical instructions have
3244 identical opcodes, complain otherwise.
3246 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3247 was reported by Roland McGrath.
3248 (unimp): Only match if exactly zero instruction. (Roland)
3249 (branches and traps): Generate all variations of these
3250 instructions with macros, based on a single call that defines
3251 each condition name and its binary representation.
3252 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3254 * valprint.c (val_print_fields): Take, and use, format parameter.
3255 This means that "p/x struct" again prints the elements in the
3256 desired format. Changed callers.
3258 * stack.c (frame_info): Use filtered output, and indicate wrap
3259 points. Remove kludgy formatting designed to avoid line wrap.
3261 * utils.c (wrap_here): If the line is already full (because
3262 we had printed a long indent or long wrapped string), do an
3263 immediate newline-and-indent.
3265 * m68k-pinsn.c (print_insn_arg): Bugfix from
3266 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3267 instruction is incorrectly disassembled as bkpt #8.
3269 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3270 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3271 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3272 and then will dump core (sometimes). I traced it back to an
3273 uninitialized symfile_name in psymtab_to_symtab.
3274 (const_vol_complaint): Add quotes to message.
3275 (define_symbol): Only believe line number if gcc_compiled.
3276 Avoid allocating symbol if we will not return it.
3278 Add target strata support so that newly established targets go
3279 into their right place in the target stack (e.g. a new exec file
3280 doesn't wipe out the ability to access the running process).
3282 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3283 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3284 and initialize it properly in all the targets.
3286 * target.h: Document strata. Change return type of push_target.
3288 * target.c (nomemory): new function for dummy memory access.
3289 (tcomplain): Rename complain, now also used in symfile.c.
3290 (push_target): Push targets within strata. New return value shows
3291 whether new target is on top of stack or not. Always keep dummy
3293 (target_files_info): Ignore dummy target.
3295 * core.c (core_open): Warn user, and skip accessing file, if the
3296 core target is not the topmost target in the stack.
3297 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3300 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3301 target_ops, it doesn't belong there since we have no regs there.
3302 Change name of target from machine => memory to clarify.
3304 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3306 * Freeze version 3.93 for release.
3308 * Makefile.dist: Handle vx-share and nindy-share subdirs
3309 properly when building gdb.tar.Z.
3311 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3312 printed in various places, so I could change just one copy.
3314 * dbxread.c, coffread.c: Change references to bfd->iostream
3315 to cast to FILE *, now that BFD avoids needing types defined
3316 in other header files.
3318 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3320 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3321 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3322 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3323 (actually gcc -Wall).
3325 * dbxread.c: Remove first_global_sym, last_global_sym, since
3326 they are never referenced.
3328 * defs.h (baud_rate): Declare.
3329 main.c: Define it, and add the -b option to set it.
3331 * gdb-int.texinfo: Add text on how to define a new host or target
3332 architecture, prompted by Per Bothner's questions about MIPS
3335 * gdb.texinfo: Document "complaints". Change doc of -q since
3336 gdb no longer prints the copyright and blurb if you specify a file
3337 name to be debugged (just like Emacs). Add doc for Nindy-specific
3338 command line flags for specifying target serial port and such.
3339 Update copyright to 1991.
3341 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3342 has taken over for us the job of ripping up executable files. The
3343 crud caused Per Bothner's port to not compile.
3345 * infrun.c (normal_stop): Avoid printing "Program exited
3346 normally" if we are in batch mode. This allows a GDB which
3347 executes a program on a target system, to behave like a Unix
3348 command (input from stdin, output to stdout, no extraneous
3351 * main.c (main): Allow additional machine-dependent command line
3352 options to be specified with the ADDITIONAL_OPTIONS,
3353 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3354 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3355 processing to occur just before the main loop with
3356 BEFORE_MAIN_LOOP_HOOK.
3357 (main): If a "core file" argument is specified, and it is not a
3358 core file, try it as a process ID to attach.
3359 (symbol_completion_function): Attempt to cope with
3360 "show screen-" TAB, not very successfully. This needs more work,
3362 (batch_file): New function, returns whether we are reading
3363 commands from an interactive tty on stdin, or from somewhere else.
3364 Called by normal_stop since it doesn't get from_tty passed down
3365 to it like many commands do.
3367 * remote-nindy.c: Handle command line options for nindy
3369 (nindy_before_main_loop): Prompt user for tty name if they
3370 don't specify it before getting to the interactive command loop.
3372 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3373 and -r command line options. Also add hook before main loop
3374 to make it easy to specify a tty.
3376 * TODO: More things to do, one done.
3378 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3380 * dbxread.c: Make complaint() calls pass pointer, not struct.
3381 Add complaints about badly formatted C++ type information
3382 (const/volatile indicator, and parse errors resulting in
3383 error_type). Fix C++ virtual member fn comment.
3384 (read_struct_type): Avoid bumping pointer if we got a parse
3385 error; this prevents our walking beyond the end of a string.
3386 Terminate loop on null char as well as semicolon.
3387 (process_one_symbol): Fix the LBRAC fix so that it uses the
3388 last previous SLINE, FUN, or SO record's PC address. C++ debug
3389 symbols did not have SLINE records in a useful order compared
3390 to the LBRAC records.
3391 (define_symbol): Handle "catch" records.
3393 * symtab.c (check_stub_type): Added new complain
3394 `stub_noname_complain' and added a consistency check to
3395 keep the debugger from crashing when finishing from an
3396 exception frame. A real fix will be needed later.
3398 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3400 * infcmd.c (attach_command): Make global.
3402 * Makefile.dist (REMOTE_OBS): Make these compile by default,
3403 but make them easy to comment out. Perhaps later they should
3404 be enabled by what CPU you configure for? FIXME.
3405 (VERSION): Roll to 3.93.
3406 (pinsn.o): Remove rule for obsolete file.
3407 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
3409 Run down a problem that manifested by printing the wrong function
3410 name in stack traces of read_ofile_symtab. Turned out that the
3411 problem was the SunOS 4.1.1 (and previous) C compiler outputs
3412 the LBRAC symbol with an address in the *data* segment, which
3413 blew our binary search through the blocks.
3415 * dbxread.c: Use the complain() facility consistently to bitch
3416 about problems in the symbol file we are reading.
3417 (finish_block): Add code to check the nesting of the blocks;
3418 complain and Procrust them to fit if wrong.
3419 (make_blockvector): Check the order of the blocks, complain
3420 [but don't cope] if wrong.
3421 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
3422 symbols to be sure their PC value is greater than the last SLINE
3423 (line number) symbol we've seen, complaining and adopting the
3424 SLINE PC value if wrong.
3426 * symfile.h (struct complaint, complaint_root, complain,
3427 clear_complaints): Add.
3428 * symfile.c (complain, complaint_root, clear_complaints): Add
3429 facility to deal with non-fatal complaints and to regularize their
3431 (symbol_file_add): Clear complaint counters to allow new complaints.
3432 (initialize_symfile): Add 'set complaints' and 'show complaints'.
3434 * dbxread.c (dbx_symfile_read): Remember the address and size
3435 of the string table for the main symbol file, so we won't read it
3437 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
3438 to avoid reading the string table yet again. Lint.
3439 (throughout): Improve filtered output, including word wrap.
3440 (read_range_type): Improve Bothner's fix to handle other types too.
3442 * utils.c: Improve line wrap implementation. Handle unlimited
3443 width by making chars_per_line unsigned.
3444 (puts_filtered): New, easy, function.
3446 * defs.h (puts_filtered): add.
3448 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
3449 call the identical sort_symtab_syms() in symfile.c instead.
3451 * expread.y: Suggest the `file' command rather than `symbol-file'.
3453 * command.h (enum var_types): Add zinteger for seroable
3455 * command.c (do_setshow_command): Handle var_zinteger. Restructure
3456 nested if's into a switch.
3458 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
3459 we did not stop because of a breakpoint (it must have been for
3460 some other reason, like a "stepi"), so don't print anything.
3462 * symtab.c: Include <sys/types.h> all the time. Now that BFD
3463 doesn't include <sys/types.h>, old SunOS's require it for
3466 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
3468 A test port of gdb-3.92.6 to the Sony NEWS.
3471 Don't normally link in remote- or vx stuff.
3472 Some of it doesn't compile, and it wastes space for 99% of the users.
3473 Remove reference to no-longer-used HAVE_VPRINTF.
3474 Fixed BFD_DEP typo to BFD_DIR.
3476 Fix cast in arg to bfd_h_getlong.
3477 Make char *prefix be const.
3478 Fix how certain range types are mapped into builtin unsigned int types.
3480 Remove 2 #includes. They cause errors (on Sony, at least),
3481 and aren't needed (they wern't in earlier versions).
3483 print_address_symbolic should never demangle labels
3484 (since it prints *assembler-level* labels).
3486 [This was superseded by the change to printcmd below.]
3489 Add some "volatile" return types to avoid warnings.
3490 If MISSING_VPRINTF add vprintf function and not just macro
3491 (since vprintf is used in printcmd.c).
3493 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
3494 (The latter isn't grokked by some PCC-based compilers.)
3496 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
3498 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
3499 * nindy-share/coffstrip.c
3500 Added some forward declarations (otherwise, gcc complains
3501 about implicit extern redefined as static).
3503 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3505 Changes inspired by Per Bothner:
3506 * printcmd.c (print_address_symbolic): Take additional parameter
3507 specifying whether to demangle.
3508 (print_address): Pass in asm_demangle to control demangling.
3509 (print_address_demangle): New fn, takes explicit arg to control
3511 * utils.c: Add new vars demangle and asm_demangle, and let them
3513 (fputs_demangled): If !demangle, just print the argument.
3514 (fprint_symbol): If !demangle, just print raw symbol.
3515 * valprint.c (val_print): Call print_address_demangle rather than
3516 print_address, to cause demangling to depend on the global
3517 rather than assembler-level demangling setting.
3518 * WHATS.NEW, gdb.texinfo: Document.
3520 * main.c (show_command): Show all settings if no arg.
3521 (initialize_main): Make "info set" the same as naked "show".
3522 * command.c (cmd_show_list): Handle prefix commands in the
3523 list, and print the name of the setting as well as its English
3524 description and value.
3526 Allow gdb functions to specify where a line should wrap if it
3527 exceeds the size of a terminal line. Use it to make the output
3529 * utils.c (set_screen_width_command): New fn, mallocs a buffer
3530 of the right size when screen width changes.
3531 (set_screensize_command, screensize_info): Remove #if 0'd fns.
3532 (wrap_here): New fn, indicates a point in the output where we
3533 should wrap the line rather than just letting it overflow at a
3535 (fputs_filtered): Implement wrapping.
3536 (n_spaces): New fn, returns a pointer to N spaces.
3537 (print_spaces_filtered): Use n_spaces.
3538 * defs.h (n_spaces): Declare.
3539 * stack.c (print_frame_info): Wrap with 4-space indent after
3540 fn name and before filename and line number.
3541 * printcmd.c (print_frame_args): Wrap with 4-space indent
3542 before each argument name is printed.
3543 * valprint.c (value_print): Wrap with no indentation before
3545 (val_print_fields): Wrap with indentation relative to nesting
3546 level before each field name.
3547 (val_print): Wrap with nesting indentation before array elements.
3548 * command.c (do_setshow_command): Avoid extra newlines,
3549 wrap with 4-space indent around values printed, end with period.
3550 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
3552 * breakpoint.c (breakpoint_1): Implement addressprint for
3553 "info breakpoints" display. Change file name and line number
3554 format to " at file:nnn" rather than " (file line nnn)".
3555 * gdb.texinfo: Document.
3558 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3560 Frozen for gdb-3.92.6 release.
3562 README, WHATS.NEW: Update for 3.92.6 release.
3564 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
3565 coffread.o from configs since it is now built by default.
3566 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
3567 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
3568 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
3569 from configs since it is now built by default.
3571 Makefile.dist: Update for release 3.92.6. Handle files that
3572 have been moved to ../include, ../getopt, or ../bfd. Add
3573 saber.suppress and tests directory. Add config.status to
3574 the release (it will say "none").
3576 coredep.c: Minor formatting fixes.
3578 These changes were made in early December but only checked in now:
3579 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
3580 nindy-share/nindy.c: lint
3581 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
3582 register values coming back from the target; we store values
3583 in target byte order everywhere.
3585 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
3587 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
3589 * valprint.c (cplus_val_print, val_print_fields): New functions,
3590 which print C++ objects. They conspire to avoid printing a
3591 virtual base class more than once, following all the twists and
3592 turns of C++ virtual base rules.
3593 (val_print): Call the above rather than do it by hand.
3595 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
3596 symbol file, not for added files like shared libs. This really
3597 needs to be generalized to a timestamp per file.
3599 * core.c (cleanup_core): Avoid coredump if no core file.
3601 * config.gdb: Accept -host or -target in place of +host or
3604 * coffread.c (find_linenos): Avoid desupported BFD interface
3605 to line numbers. We still read them manually rather than using
3606 BFD's "generic" features.
3608 * gdbrc.tex, threecol.tex: Add GDB reference card and its
3610 Makefile.dist: Add refcard to OTHERS list for creating tar files.
3612 * Makefile.dist: Eliminate use of $< in explicit targets.
3614 * readline/Makefile: Use $< rather than $*.c, which does not
3615 include the VPATH in GNU Make.
3617 * tconfig/i960-bout, tconfig/i960-coff: These are identical
3618 copies of tconfig/i960, added for global configuration
3619 compatability. All i960 versions can read both coff and b.out.
3621 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
3622 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
3625 * TODO: Think of more things to do.
3627 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
3629 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
3630 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
3631 64-bit float conversion.
3633 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
3634 equivalent to sun?os4 so global config works.
3636 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
3638 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
3640 * main.c: Only declare linesize once; declare pagesize not at
3641 all, since it is never used.
3642 (main): Clear newly allocated line before it is used.
3644 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
3646 Further stabilization for the Intel 960.
3648 * Makefile.dist: Parameterize the location of the "include"
3649 and "bfd" directories, as well as "getopt". Add symfile.c.
3650 Link in both dbxread and coffread. Fix up "make depend" to
3651 rewack the locations of include, bfd, and getopt in its output.
3653 * README: Document moving include files, improve some of
3656 * coffread.c: Move common code out to symfile.c. Change
3657 symbol_file_command style interface to use new *_symfile_init
3658 and *_symfile_read interface under BFD. Use BFD internal
3659 info to locate line table, symbols, etc.
3661 * core.c (core_fetch_registers): Rename to get_core_registers
3662 to avoid confusion with fetch_core_registers.
3663 (register_addr): Move to coredep.c, which is already machine
3664 dependent. This leaves core.c pretty clean of dependencies.
3666 * coredep.c (register_addr): Accept this routine from core.c.
3668 * dbxread.c: Move common code (with coffread.c, etc) into new
3669 symfile.c. Each psymtab now contains a pointer to the
3670 format-dependent function that knows how to read it in. Make
3672 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
3673 (process_one_symbol): Add code to complain about a "compiler bug
3674 we muzzle here", if we actually see it.
3676 * eval.c (evaluate_subexp): Insert missing "break" statements
3677 in code that determines whether a variable is an lvalue in
3678 memory, register, or whatever. I detected this via a compiler
3679 bug in which it *almost* mashed out the whole switch statement.
3681 * gdb-int.texinfo: Add minor sections on configuring gdb for
3682 release, and about the README file.
3684 * infcmd.c (registers_info): Fix formatting somewhat. Still
3685 not as pretty as before, but it handles byte swapping.
3687 * remote-nindy.c: If data cache routines are interrupted while
3688 waiting for the remote end, be sure that any uninitialized cache
3689 blocks are on the free list, not on the valid list!
3691 * symfile.h: Flesh out this header file with all the various
3692 routines and variables that have been merged in from dbxread.c
3693 coffread.c, and symtab.c to symfile.c.
3695 * symfile.c: New file, containing code common to dbxread.c,
3696 coffread.c, and some code from symtab.c. All generic code for
3697 reading symbol files should be in here now.
3698 (unrecord_misc_function): Remove unused function.
3700 * symtab.h: Remove file-reading things to symfile.h.
3702 * symtab.c: Remove file-reading things to symfile.c.
3704 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
3705 to decode i960 fault types.
3707 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
3708 target.c: Change type of the "resume" function from int to void,
3709 since its result was never used.
3711 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
3713 * main.c: Replace "stupid" with "caution"; you now "set caution
3716 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
3718 * infcmd.c (do_registers_info): Call val_print to deal with the
3719 byte order of the registers being printed. FIXME, this makes
3720 the formatting of the output uglier.
3722 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
3723 defined, call it for signals the debugger doesn't itself use.
3724 The i960 uses this for more detailed fault information.
3726 * remote.c (remote_open): If arg is null, print help rather than
3729 * sparc-xdep.c (register_valid): Avoid declaring size, since
3730 various modules will think of various sizes depending on the
3731 architecture of their tm-file. FIXME, we need protection against
3732 actually entering one of those modules, which would clobber
3733 storage if not for the target architecture compiled into gdb.
3735 * stack.c (up_command, down_command): Always print the frame
3737 (up_silently_command, down_silently_command): New commands
3740 * i960-pinsn.c (reg), i960-tdep.c: Lint.
3742 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
3743 more parameters than it used to.
3745 * findvar.c (registers): Increase slop to 256 bytes, which should
3746 protect us against even most RISC machines with large register
3748 (locate_var_value): Move declaration inside related ifdef.
3750 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
3751 throughout, to avoid throwing away buffered input from the board.
3752 (nindy_wait): Supply_register takes addr_of_value, not value.
3753 (i960_print_fault): Renamed from i80960_fault.
3754 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
3755 (nindy_store_registers): Avoid regs_changed stuff, just stuff
3757 (nindy_create_inferior): Don't bother to write PC_REGNUM since
3758 we can set the PC in the call to proceed(). Unpush nindy_ops
3759 before pushing it on top, to avoid message to user. Eliminate
3760 commentary from Unix machines that just misleads here.
3761 (reset_command): Fix error message to suggest target command.
3763 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
3765 Release 3.92.5 as frozen.
3767 Stabilize the merged release...with help from lint, Saber C,
3770 Everywhere: Add include files needed to declare return types
3771 of functions called.
3773 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
3775 * breakpoint.h: Add undeclared breakpoint functions, and some
3776 functions for display handling since I couldn't think of a better
3779 * breakpoint.c (insert_breakpoints): Make code for disabling
3780 shared library bkpts more likely to work. It's used when we
3781 rerun a program and stop before the shared library has been
3783 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
3784 cast from pointer, so it squeezes through catch_errors.
3785 (bpstat_stop_status): Fix logic broken some time ago. We now
3786 always create a bpstat if the stop address matches a breakpoint,
3787 even if we don't stop there -- just like the old code used to do
3788 before I got my fingers into it (sigh).
3789 (breakpoint_1): Print "ignore count" after "stop only if"
3790 condition, since that's how it actually works.
3791 (mention): Handle watchpoints as well as breakpoints.
3792 (watch_command): use set_raw_breakpoint and mention to do most
3793 of the work (and initialize all the fields!). Only pass one
3794 arg to parse_c_expression, since that's all it takes.
3796 * command.c (not_just_help_class_command): Rename arg to args
3797 since we ignore "unused argument" warnings on vars named "args".
3798 inflow.c (child_terminal_info): ditto.
3799 infptrace.c (kill_inferior): ditto
3800 main.c (catch_errors, version_info, quit_command, pwd_command,
3801 source_command, dump_me_command, editing_info,
3802 set_history_size_command, set_history, show_history,
3804 stack.c (locals_info): ditto
3805 target.c (target_files_info): ditto
3806 valprint.c (set_input_radix, set_output_radix): ditto
3808 * core.c: Remove old variables for handling core and exec file
3809 sections (data_start, data_end, stack_start, stack_end,
3810 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
3811 text_end, exec_data_start, exec_data_end, text_offset,
3812 exec_data_offset, data_offset, stack_offset). They're
3813 superseded the more general build_section_table and
3815 (get_exec_file): Mention the `file' command.
3816 (read_memory_check): Rename to memory_error, and only call it
3817 in the case of an actual error.
3818 (read_memory, write_memory): call memory_error.
3819 (core_fetch_registers): Register section name is ".reg".
3821 coredep.c: Remove a bunch of crud now that all this file does
3822 is pull the registers out of a core file.
3823 (fetch_core_registers): Rewrite to actually work, I hope.
3825 dbxread.c: Use a.out.gnu.h, not system a.out, now.
3826 Replace index() with strchr(). Remove all the pre-BFD macro
3827 definitions for accessing the symbol file.
3828 (struct dbx_symfile_info): Encapsulate the information that
3829 dbx_symfile_init needs to pass to dbx_symfile_read in this
3832 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
3833 dbx_symfile_discard): Rearrange symbol file reading to divide
3834 the format-specific part from the format-independent part,
3835 leaving the format-independent part such as file name expansion
3836 and opening in symtab.c. This replaces
3837 partial_symbol_file_open and partial_symbol_file_read.
3838 Symbol_file_read, add_file, add_file_target_command,
3839 add_file_addr_command move to symtab.c. Pass an explicit
3840 "mainline" flag for when reading the main symbol table, rather
3841 than relying on the offset address to be zero or nonzero.
3843 (dbx_symfile_read): Don't allow void *'s to be printed as
3845 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
3846 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
3847 macro" debug version really work.
3848 (read_dbx_symtab): Remove unref'd parameter inclink.
3849 Avoid swapping N_SLINE symbols, for speed.
3850 Merge N_TEXT!N_EXT case with the other external symbol
3851 definitions' case. Add comments.
3852 (start_psymtab): Allocate the symfile name in the psymtab on
3853 the psymbol_obstack, rather than using the caller's storage.
3854 (end_psymtab): Only allocate a dependencies list if there are
3856 (psymtab_to_symtab_2): Use BFD when reopening file to read
3857 its symbols for real.
3858 (read_struct_type): Add FIXME comments where it needs work
3860 (read_huge_number): Add FIXME about overflows.
3861 (read_range_type): Add FIXME about comparing a long to 1<<32.
3863 * coffread.c: Minor changes to move things closer to the new
3864 regime with symtab.c and dbxread.c Major work is still needed
3867 * exec.c (exec_file_command): Remove old variables (see core.c
3869 (xfer_memory): If memory transfer is right at the end of a
3870 section, don't lose.
3872 * findvar.c (get_saved_register): If value is in a real
3873 register, LVAL is lval_register, not lval_memory.
3875 frame.h: Declare print_sel_frame and record_selected_frame.
3877 gdb-int.texinfo: New file, for GDB internals documentation.
3878 Very simple, unformatted doc of cleanups is there for now.
3880 gdbcore.h: Remove obsolete variables that described a.out
3881 section addresses and offsets. (See core.c above.)
3882 Declare fetch_core_registers and registers_fetched.
3884 getopt.c: Declare char *alloca(); even on SPARC.
3886 infcmd.c (run_command): Call target_kill rather than
3888 (step_command, next_command, stepi_command, nexti_command):
3889 Declare from_tty parameter even though we don't use it.
3890 (run_stack_dummy): argument BUFFER is a char array, not
3891 a pointer to REGISTER_TYPE.
3892 (finish_command): using_struct_return needed a value *,
3893 not a struct symbol *.
3895 * infptrace.c (child_xfer_memory): To avoid dependency on
3896 where sections are in memory, try PT_WRITE_D and if that fails,
3897 try PT_WRITE_I. Most Unixes don't care which you use.
3899 * infrun.c (step_resume_break_shadow): Change to array to
3900 match other breakpoint shadow storage.
3901 (clear_proceed_status): Pass address of bpstat to
3902 bpstat_clear, not the bpstat itself.
3903 (child_create_inferior): FIXME comment about if the child
3905 (start_inferior): Remove old function.
3906 (child_open): Use target_kill rather than kill_inferior.
3907 (wait_for_inferior): Ditto.
3908 (insert_step_breakpoint, remote_step_breakpoint): Use
3909 new step_resume_break_shadow.
3911 * inftarg.c (child_wait): If all child processes die,
3912 pretend that the one being waited for exited with signal 42.
3914 * main.c (command_line_input): When scanning for comments,
3915 don't coredump on unclosed quotes.
3916 (quit_command): Use target_kill rther than kill_inferior.
3917 (_initialize_main): Rename class_user from "user" to
3920 * printcmd.c (print_command_1): Initialize "fmt" if no format
3921 is specified by the user.
3922 (print_frame_args): Only add to args_printed if we are
3923 actually fetching args from the stack (avoiding undefined

3927 * remote-eb.c (eb_open): Avoid coredump on no argument.
3929 * remote-nindy.c: Bring out of Intel environment into new
3930 target environment. Remove all conditional compilation on
3931 I80960. Massive hacking throughout.
3932 (nindy_xfer_inferior_memory): New routine stolen from
3934 (nindy_create_inferior): New routine pieced together, probably
3935 not quite working yet.
3936 (nindy_ops): New target_ops struct for nindy.
3938 * remote-vx.c: Use write_memory rather than target_write_memory
3939 to get error checking.
3940 (vx_add_file_command, vx_open): Use symbol_file_add rather than
3942 (vx_create_inferior): Use target_terminal_ours...
3944 * signame.c (_initialize_signame): Always initialize, since
3945 we need the table for things other than psignal.
3947 * solib.c (solib_add): Use symbol_file_add, not add_file.
3948 (solib_address): Return boolean result rather than struct
3949 pointer which nobody else knows the type of.
3951 * sparc-tdep.c, valops.c: Use write_memory rather than
3952 target_write_memory, to get error checking.
3954 * stack.c (locals_info, catch_info, args_info,
3955 get_selected_block, frame_command, up_command): Use
3956 target_has_stack, rather than have_inferior_p or
3959 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
3961 * symfile.h: New file, defining the interface between the
3962 generic and object-file-specific symbol reading code.
3964 * symtab.c: Move generic symbol-reading interface to symtab.c,
3965 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
3966 table to map BFD targets to symbol-reading modules in GDB.
3967 Change index to strchr.
3968 (lookup_struct_elt_type): Use error() rather than hand-made
3969 simulations thereof.
3970 (lookup_partial_symbol): Speedup slightly when length == 0.
3971 (symbol_file_add): New function.
3972 (symbol_file_command): Call it.
3973 (symfile_open, symfile_init): New function.
3974 (add_file_target_command, add_file_addr_command): moved from
3977 * target.c (target_command): use target_kill.
3979 * target.h (target_files_info): Don't declare, never called
3982 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
3983 files to determine stack end address.
3985 * valarith.c (value_x_binop, value_x_unop): Change error message
3986 to be more useful. Pass proper argument to value_struct_elt.
3988 * valops.c (value_assign): FIXME comment that long long
3989 bitfields will break here.
3991 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
3992 Update `make saber_gdb' to work better.
3994 * TODO: A woman's work is never done.
3996 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
3997 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
3998 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
3999 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4000 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4001 valops.c, valprint.c, exec.c: Lint.
4004 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4006 Continuing Intel 960 port merge of GDB.
4008 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4009 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4010 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4011 Wack over "make depend" so it handles files in subdirectories
4012 vx-share, nindy-share, bfd, and in the current directory.
4014 * blockframe.c (get_prev_frame_info): Remove fatal error
4015 if stack not defined.
4017 * core.c (core_open, core_detach): New functions that handle
4018 the old "core-file" command as "target core" and "detach" instead.
4019 (core_file_command): Call them.
4020 (core_xfer_memory): Use common routine xfer_memory.
4022 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4023 dbxread now uses bfd for everything but symbol reading itself.
4024 BFD internals are used to drag out the relevant file offsets.
4025 (partial_symbol_file_open): Change args all around for BFD.
4027 * symtab.c: Rename "value" to "val" everywhere, so we can
4029 (symbol_file_command): New command, moved from dbxread.c
4030 and coffread.c. It uses BFD to read the file, then vectors
4031 based on its type, to dbx or coff symbol readers.
4032 * symtab.h: Extern a few vars for symbol_file_command.
4034 * target.h: Breakpoint takes a char * save area, not a char **.
4036 * valprint.c (val_print): When unpacking bitfields, offset
4037 the address in gdb of the value, if it is declared with a shorter
4038 type. Remove the last "runtime kludge test" of host byte order.
4040 * utils.c: Remove old my_bfd_read routine.
4042 * stack.c (frame_info): Use target_has_stack. Print program counter
4043 register's actual name rather than "pc", since it's called the
4044 "ip" (instruction pointer) on the i960 (sigh).
4046 * target.c (target_command): Add command for selecting a target
4047 type and calling its open routine. This is used for initiating
4048 communication with a particular target, in a generic way.
4050 * tm-i960.h: Update for modern gdb. Remove semicolons from
4051 various macros. Handle reading struct return convention, and
4052 error-out attempts to return structs with the "return" command.
4053 Be sure gdb doesn't think we know how to call functions in the
4056 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4057 to i960_xxx in lower case.
4058 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4059 not being defined yet.
4061 * remote.c (remote_open): Call start_remote to initialize
4062 wait_for_inferior during open.
4063 (remote_xfer_inferior_memory): Return length written rather
4066 * remote-vx.c (target_command -> vx_open): Use new generic
4068 * remote-eb.c, inftarg.c, exec.c: ditto.
4070 * infrun.c: Fix comments.
4071 (attach_program -> child_open): Use new generic target command.
4072 (wait_for_inferior): Clear saved register values before target_wait,
4073 so target_wait can set some of them if convenient.
4075 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4076 Return success indicator, not void.
4077 (child_xfer_memory): Avoid fetching initial word if we'll
4078 overwrite it anyway.
4080 * infcmd.c (attach_command): Use new generic target open routine.
4081 (_initialize_infcmd): Update doc on attach and detach commands.
4082 (do_registers_info): Merge in a byte-order problem as a FIXME
4085 * findvar.c (find_saved_register): Avoid problem in current frame.
4086 (read_relative_register): Ditto.
4087 (write_register): Convert byte order on the way out.
4089 * exec.c (file_command): Add.
4090 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4091 (xfer_memory): Common function between core_xfer_memory and
4093 (exec_xfer_memory): Use it.
4095 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4097 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4098 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4099 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4101 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4103 Merge Intel 960 port of gdb, continuing...
4105 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4106 symbol_file_command): Pass from_tty arg to hush 'em up.
4108 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4109 Add magic numbers for 960 COFF format.
4111 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4113 Merge Intel 960 port of gdb, from Intel "1.2" release.
4115 CHANGE_LOG entries from their port, which was based on

4119 Remove temp file if download is interrupted.
4121 Wed Aug 1 09:08:33 PDT 1990
4122 Now uses binary protocol to talk to NINDY.
4123 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
4124 Times out after 5 seconds when trying to talk to NINDY.
4126 Tue May 29 12:54:49 PDT 1990
4127 Added variable baud rate (-b switch).
4128 Source code reorganization.
4130 Thu Apr 26 11:09:55 PDT 1990
4131 More cleanup of batch mode; specifically, execute "-s", "-e", and
4132 "-se" switches as soon as they are encountered on the invocation line.
4134 Fri Apr 20 13:47:15 PDT 1990
4137 Thu Apr 19 09:54:28 PDT 1990
4138 Add 'reset' command.
4140 Wed Apr 18 09:48:07 PDT 1990
4141 After opening remote tty, wait for 1 second to go by without input
4142 from it before trying to talk to NINDY (fixes problems with the
4143 Heurikon HK80/V960E).
4145 Mon Apr 4 16:33:05 PDT 1990
4146 Some output was not being suppressed in 'batch' mode.
4148 Thu Mar 22 15:31:11 PST 1990
4149 Ask user if old symbol table should be deleted when new file is
4152 Allow user to run a program downloaded before gdb960 was brought up.
4154 Correct "exec-file" help message for i80960 context.
4156 Correct bug in calculating user space address: could occasionally
4157 corrupt user program.
4159 Make sure to zero low-order bits in rip's because of bug in 960CA
4160 A-step part: could cause operation faults when "next"ing across
4163 Correct bug that made it impossible to get source line numbers for
4164 code loaded at addresses higher than 0x7fffffff.
4166 Wed Jan 10 12:43:22 PST 1990
4167 Open remote tty for exclusive use.
4169 Fri Jan 5 12:14:42 PST 1990
4170 Correct disassembly (CA manual was right after all):
4171 opcode for sysctl is 0x659
4173 Mon Oct 23 12:03:04 PDT 1989
4174 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4176 Mon Oct 16 14:15:09 PDT 1989
4177 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4179 Mon Oct 2 15:56:31 PDT 1989
4181 Added 960CA disassembly support.
4183 To simplify maintenance:
4184 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4186 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4187 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4188 - made disassembly interface identical to that in gdmp960.
4192 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4194 * target.h: Allow targets to stack. Add target_has_memory,
4195 _registers, etc. Restructure memory access and "info files"
4196 to walk the target stack.
4197 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4198 target.c: Change tables to match target.h.
4199 * inflow.c (child_mourn_inferior): pop child_ops.
4200 (generic_mourn_inferior): Use new has_stack flag.
4201 * infptrace.c (child_xfer_memory): New memory regime.
4202 * inftarg.c (child_files_info): New "info files" regime.
4203 * remote-eb.c: New memory regime, new info files.
4204 * remote-vx.c: New memory regime, new info files. Now use
4205 separate targets for VxWorks attachment to machine, and
4206 actually running a process under VxWorks, since one has
4207 stack & execution & regs and the other doesn't.
4208 * remote.c: New memory regime, new info files.
4209 * sparc-xdep.c (fetch_core-registers): New memory regime.
4210 * target.c: New routines and support for stacked targets,
4211 new memory regime, new info files regime.
4214 Generalize section handling for an arbitrary number of sections,
4215 including use of the new BFD (binary file) library.
4216 * gdbcore.h: Add struct section_table.
4217 * exec.c (build_section_table): Iterate all sections and
4218 record what gdb needs to know about them.
4219 (exec_command): Use it.
4220 (exec_xfer_memory): Use the table.
4221 (exec_files_info): Print the table.
4222 * core.c (core_file_command, core_xfer_memory, core_files_info):
4224 * source.c (find_source_lines): Use bfd_get_mtime.
4225 * dbxread.c: Quick changes to make it compile with new BFD.
4226 * utils.c (error): Avoid using bfd_error in generic routines.
4228 * core.c (core_fetch_registers): Get from the ".regs" section of
4230 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4232 * inferior.h (attach_flag): Export.
4233 * infcmd.c (run_command): use new target_create_inferior.
4234 * infrun.c (child_create_inferior): Don't return result.
4235 * Makefile.dist (VERSION): 3.91.4.
4237 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
4239 * breakpoint.c (bpstat_num): Handle breakpoints which have
4240 since been deleted, such as temporary breakpoints.
4241 infcmd.c (program_info): ditto.
4243 * core.c (core_file_command): Display the frame where the core
4248 * remote-vx.c (target_command): Merge in target command from
4249 targ-vx.c. A few other cleanups.
4251 * TODO, Projects: Lots more stuff to do...
4253 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4255 Massive changes to wall off the remote-debugging interface
4256 behind a function vector. The port to handle VxWorks targets
4257 is also part of this.
4259 All files: Replace references to renamed functions,
4260 remove references to remote_debugging, remove references to
4261 have_include_file, have_core_file in favor of target_has_stack,
4262 target_has_memory, etc.
4264 * Modularize the breakpoint interface.
4265 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4266 a breakpoint instruction.
4267 breakpoint.c: struct breakpoint's shadow_contents now sized as
4269 (insert_breakpoints): Vector to target to install breakpoints.
4270 (remove_breakpoints): Vector to target here too.
4271 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4272 sparc-tdep.c (single_step): Use new breakpoint interface for
4273 the single-step breakpoints.
4274 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4275 New file, contains routines to insert and remove breakpoints by
4276 reading out the old contents and later replacing them. This is
4277 how ptrace breakpoints work, and many remote systems as well.
4279 * tm-vxworks68.h: New config file, overrides a few things for
4280 Wind River's preferences.
4282 * target.h: New file, for transfer vector used to talk to the
4283 inferior (child, attached, core, exec, remote, etc). All accesses
4284 to the thing being debugged should come through these vectors.
4285 target.c: New file, routines to handle transfer vector.
4286 (various files): Add transfer vectors XXX_ops for the various
4287 targets and pseudo-targets (core files, etc) we support.
4289 * breakpoint.c (bpstat_stop_status): Further explorations of
4290 watchpoints and why things don't work all the time.
4291 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4293 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4294 the local gdbinit if it doesn't already have it.
4296 * core.c (core_ops): add and install.
4297 Allow core debugging without exec file.
4299 * dbxread.c (free_and_init_header_files): Merge two fns.
4300 (end_symtab): Free named symbol table when a new version comes in.
4301 (read_dbx_symtab): Relocate all kinds of symbols with base
4302 address. First step toward handling different text, data, bss
4304 (add_file_addr_command): Renamed add_file_command.
4305 (add_file_command): Vector to remote handler.
4306 Add "load" as an alias for "add-file" command.
4308 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4309 non-returning functions.
4311 * exec.c: Add exec_ops, and push it as a target when an exec
4314 * infcmd.c (run_command): Pass executable file name and arg list
4315 separately when starting an inferior. Permit "run" when no exec
4316 file is specified, for VxWorks.
4317 (detach_command): Move to child_detach in inftarg.c.
4319 * inftarg.c: New file. Unix-child-specific routines, and the
4320 child_ops structure.
4322 * inferior.h (registers): Export "registers" as the way for
4323 target dependent register handlers to find gdb's local copy of
4324 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4325 since it is now used by places that want wait_for_inferior to
4326 handle the grunge but want to see every trap from the inferior.
4328 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4329 Eliminate remote_debugging hooks in terminal handling.
4331 * infrun.c: Replace start_inferior with child_create_inferior.
4332 Move all the hair of Unix shells and ptrace idiosyncracies into
4333 child_create_inferior, so remote handlers don't have to deal.
4334 Remove running_in_shell. Rename stop_after_attach to
4335 stop_soon_quietly, and use it in a few other places where we want
4336 to just call wait_for_inferior and get control back on the first
4337 trap. trap_expected now never takes a value > 1.
4338 (init_wait_for_inferior): Initialize static vars when a new
4341 main.c (gdbinit): Add new hook for .gdbinit file name, let
4342 it be overridden by config files as GDBINIT_FILENAME.
4343 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4344 Both of these are used for VxWorks gdb.
4346 mcheck.c: rename include file "gmalloc.c" to avoid problems
4347 with system include file "malloc.c".
4349 param-no-tm.h: New include file, same as param.h but does not
4350 include the default "tm.h" file. This is used in files where
4351 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4353 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4355 remote-vx.c: New file, VxWorks remote debugging support. Uses
4356 RPC routines that are shared with the target system, in directory
4359 remote.c: Vectorize remote interface.
4361 source.c: Globalize source_path, and make an alias "l" for "list"
4362 since we now have the "load" command.
4364 sparc-xdep.c: Use new param-no-tm.h.
4366 symmisc.c (free_named_symtab): Add new function from Wind River.
4367 However, ifdef it out for now while we think about what it should
4370 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4372 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4373 non-Unix-children handle this with their own code in the target
4376 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4377 source and target lists. Add vx-share to default list of include
4378 directories. Add new files to src and target lists: mem-break,
4379 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4380 ${srcdir} versions of munch and createtags are used.
4382 * valops.c (find_function_addr): Split out of call_function.
4383 (call_function_by_hand): Rename call_function; this function
4384 calls functions in the target by laboriously patching the target
4385 word-by-word with the right stack, args, regs, etc.
4388 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
4390 Handle AMD 29000 a bit better.
4392 * remote-eb.c (readchar): Mask received char log to make it readable.
4393 (remote_start): Pass arguments down to executing program.
4394 Make startaddr unsigned.
4395 infrun.c (start_inferior): Accept args, pass them to
4397 infcmd.c (run_command): Pass args down to start_inferior.
4399 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
4400 the target object file format.
4401 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
4403 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
4404 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
4406 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
4408 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
4409 * TODO: We did a few things, we have more to do though.
4411 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
4412 * inflow.c (inferior_died): Clear deferred stores.
4414 * Debug problems with dummy frames and calls to the inferior.
4415 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
4416 * sparc-tdep.c (do_restore_insn): Simplify.
4417 (sparc_frame_find_saved_regs): Simplify and fix what we find.
4418 (sparc_push_dummy_frame): Simplify and fix what we push.
4419 (sparc_pop_frame): Slightly more hair here, deciding whether
4420 we are restoring a saved PC or returning to a return address in %i7.
4421 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
4423 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
4424 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
4425 * obstack.h (chunkfun): ditto.
4426 * defs.h (xmalloc, xrealloc): ditto
4428 * utils.c (quit): Grab the terminal from the child if necessary.
4430 * inflow.c (term_status_command): Rename to term_info, change
4433 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
4434 (is_delayed_branch): Speed up.
4435 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
4436 Still missing some float ops, and needs testing.
4438 * Support for input and output radixes other than base 10
4439 * defs.h (input_radix, output_radix): Declare.
4440 * expread.y (yyparse, parse_number): Handle changes of input
4441 radix, and ambiguous names-or-numbers in radixes >10.
4442 * printcmd.c (print_scalar_formatted): Print formatted hex
4443 numbers in varying column widths.
4444 * valprint.c (val_print): Use output_format to print scalar ints.
4445 (set_input_radix, set_output_radix, set_radix): Create.
4446 (set_output_radix): Set output_format from output_radix.
4447 (_initialize_valprint): add `set radix' but leave the others off.
4449 * main.c (execute_command): Let stupid questions be turned off.
4450 (_initialize_main): Handle "set stupidity", etc.
4452 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
4453 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
4455 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
4457 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
4458 bfd stuff is still screwed up, but with some manual work, it
4461 * breakpoint.c (bpstat_do_actions): Start over if a command
4462 proceeds the inferior, since the inferior will have stopped and
4463 will need to have its new stop-actions taken care of.
4465 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
4466 compiler fits, simplify it.
4468 * gdb.texinfo (directory command): Doc new dir command.
4469 source.c (directory_command): "dir" now puts things on the front
4470 of the path, moves dups up front, and handles multiple names
4471 on the command line, inserting each one in order. It also
4472 blows away cached line and full_filename info.
4474 * stack.c (backtrace_command): Skip "more stack frames follow"
4477 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
4478 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
4479 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
4480 The only odd one was Gould NP1, which had defined vprintf to
4483 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
4484 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
4485 variable, inspect_it.
4486 valprint.c (print_string, val_print): Use the global inspect_it
4487 to indicate whether to print in Epoch style or normal style.
4489 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
4491 * printcmd.c (call_command): add an alias for the "print" command
4492 which runs expressions and doesn't print the result if void.
4493 (print_command_1): implement it.
4495 * command.c: Remove #if 0'd code. Initialize all the fields
4496 in add_cmd (). Rename do_nothing_command to
4497 not_just_help_class_command, and make it externally visible.
4498 command.h: add user_commands to struct.
4499 * main.c (define_command): Don't overload c->function with a char
4500 string as well as a function pointer.
4502 * eval.c (evaluate_subexp): Reinstall tiemann changes to
4503 calling convention of value_struct_elt () that got dropped in
4506 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
4507 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
4509 * tm-sparc.h (POP_FRAME): replace some constants with defines.
4511 * sparc-xdep.c (store_inferior_registers): defer stores to regs
4512 until a good time (e.g. when we are about to run the child),
4513 saving ptrace calls.
4514 * infrun.c (proceed): handle DO_DEFERRED_STORES.
4515 * tm-sparc.h: define DO_DEFERRED_STORES.
4517 * sparc-xdep.c (store_inferior_registers): when storing float
4518 registers, don't store stack regs too. When storing the SP,
4519 however, DO store the stack regs too. This fixes a bug in which
4520 the dummy frame is not recognized when a call_function finishes,
4521 because its frame pointer (in the stack regs) was never
4523 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
4524 even though we don't know how to read them from an inferior.
4525 valops.c (call_function): Comment about storing SP.
4527 * infrun.c (save_inferior_status): Save away the original bpstat
4528 chain so it can be restored later. Install the copied version for
4529 use by whoever saved the status. It will be blow away by
4530 restore_inferior_status, and the original chain restored. This is
4531 important for people who have pointers into the original.
4533 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
4534 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
4535 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
4538 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
4540 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
4541 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
4542 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
4544 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
4546 * Merge Mike Tiemann's multiple inheritance changes from Sun.
4547 Store the baseclasses in a type struct starting from array element
4548 0 rather than from the unusual array element 1.
4550 dbxread.c: the above.
4551 (virtual_context): Add
4552 Read new debug information about which virtual function table
4553 a virtual function is from, and store it in fn_field.fcontext.
4555 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
4556 TYPE_FN_FIELD_STATIC_P.
4558 symtab.c: the above.
4559 valops.c: the above. Handle pointer casts of object *'s.
4560 (search_struct_method): Add.
4561 (value_struct_elt): First arg is now a pointer to a value, and is
4564 valprint.c: the above.
4565 values.c (value_virtual_fn_field): Add type arg. Handle
4566 offsetting to the proper object when calling virtual fns.
4568 (baseclass_addr): Add valuep arg.
4570 * README: Document the current state of BFD config (missing).
4571 * TODO, ChangeLog, Makefile.dist: Roll version.
4572 * WHATS.NEW: Add summary of changes since 3.5.
4574 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
4576 * dbxread.c (read_struct_type): Clear bit vectors whenever
4578 symtab.c (B_CLRALL): define.
4580 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
4581 using == rather than =. Huh... This fixes the dreaded problem
4582 wherein builtin_type_int becomes TYPE_CODE_FLT.
4584 * core.c (info_files): Show the inferior pid.
4586 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
4587 already knows how to look in the source directory.
4589 * Remove psymtab hair from many places. Remove duplicated code
4590 for searching symbol tables. Hide psymtabs from most places.
4591 Make it fast to get from a psymtab to its symtab.
4593 blockframe.c (blockvector_for_pc): Remove psymtab hair.
4594 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4595 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4596 dbxread.c: export psymtab_to_symtab, make it work if called N times.
4597 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
4598 new symtab completely. New psymtabs get symtab pointer
4599 initialized to zero. Remove MI warning printf.
4600 symtab.h: Comments. Add psymtab to symtab pointer.
4601 (PSYMTAB_TO_SYMTAB): New macro.
4602 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
4603 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
4605 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
4607 (print_frame_info): Avoid special-casing symbols that have not yet
4610 * source.c (open_source_file): Quick path if we have already
4611 located the source file by its full name.
4613 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
4614 find_pc_psymtab. When a name is found in the misc function
4615 vector, search the symbol table for its mangled name, not the
4616 name that the user typed.
4618 * bfd.h: Fix missing comment terminators, make #endifs match.
4620 * valarith.c (value_less): Handle unsigned int comparisons.
4621 Add FIXME about pointer compares, which assume host and target
4622 pointers are the same.
4624 * command.c (do_nothing_command): lint
4625 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
4626 fix comments on debug symbol format for visibility. Actually set
4627 visibility of symbols.
4628 main.c (echo_command): lint; use <readline/history.h>.
4629 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
4630 obstack.h (_obstack_blank): Rearrange pointer math to avoid
4631 pointing past end of allocated memory; saber complains.
4632 obstack.h: Declare the external functions that we use.
4633 valarith.h: use <string.h>
4634 solib.c (solib_add): lint.
4636 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
4638 * main.c (initialize_main): Default info_verbose to off, now that
4639 symbol reading is fast.
4640 (quit_command): Avoid clobbering exec_bfd while quitting.
4642 * Initial BFD (binary file diddling library) merger:
4643 coffread.c: Change AOUTHDR to struct exe_hdr.
4645 core.c: initialize initialized data at compile time.
4646 (core_file_command): Move from coredep.c, convert to bfd.
4647 (xfer_core_file): Convert to bfd.
4648 exec.c (exec_file_command): use bfd routines.
4650 mips-tdep.c: Remove exec_file_command and friends.
4653 * coredep.c: (fetch_core_registers) Convert core_file_command to
4654 fetch_core_registers.
4655 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
4657 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
4658 (my_bfd_read): More bogosity, which I don't think we call.
4659 (program_name): Remove this atrocity asap!
4661 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
4664 values.c: allocate_repeat_value was not clearing the
4665 optimized_out field.
4666 (value_static_field): minor stylistic fix (wrong macro was used).
4667 valops.c (value_struct_elt_for_address): didn't work for C++
4670 * signame.c (_initialize_signame): Initialize signal names once.
4672 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
4673 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
4674 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
4676 * remote-eb.c: Support user-settable baud rates on the serial port.
4678 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
4680 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
4682 * tconfig/sun3os4: Remove warning about native assembler,
4683 since it also occurs in the xconfig file.
4685 * findvar.c (registers): Allocate some slop after `registers'
4686 to prevent stray accesses from trashing the next variable.
4688 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
4689 on the sun-3, by changing the #ifdef from `sun3' (which is not
4690 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
4691 vars, which happened to follow `registers' in the executable.
4693 * readline/history.c (history_search): Heed gcc-2's advice
4694 and parenthesize && inside ||).
4696 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
4697 tm-29k.c: Insert FSF copyright headers.
4699 * remote-eb.c: Better comments.
4701 * Makefile.dist: Update to 3.91.6.
4702 * TODO: note PREPARE_TO_STORE problem.
4704 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
4706 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
4708 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
4710 * infrun.c (wait_for_inferior, at end): Don't set up
4711 prev_* if the inferior no longer exists.
4713 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
4714 CANNOT_EXECUTE_STACK.
4715 valops.c (call_function): Use it.
4717 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
4719 * inferior.h (PC_IN_CALL_DUMMY): New macro.
4720 infrun.c (wait_for_inferior, 2 places): Use it.
4722 * values.c (value_being_returned): Only use
4723 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
4725 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
4726 right thing for remote-eb.c.
4728 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
4729 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
4731 * blockframe.c: Put get_frame_saved_regs inside #if !defined
4732 (FRAME_FIND_SAVED_REGS).
4734 * findvar.c ({fetch,store}_registers): Check for
4735 REMOTE_{FETCH_STORE}_REGISTER macro.
4737 * findvar.c (get_saved_register): Add argument lval and
4738 change meaning of argument addr.
4739 findvar.c: Change calls to get_saved_register to reflect
4740 new calling convention.
4741 valops.c (value_assign): Use get_saved_register instead of
4742 find_saved_register.
4744 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4746 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
4747 an (uninitialized) pointer to one. Use "&" when passing it
4750 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4752 * coffread.c (getfilename): Use DGUX x_offset and x_name if
4755 * coffread.c (symbol_file_command): Put semicolon after
4757 Put safe_to_init_tdesc_context in #if defined (TDESC).
4758 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
4759 coffread.c: #include <sys/stat.h>.
4760 (read_coff_symtab): Typo: in_source_files -> in_source_file.
4761 Add missing ')' in check for "lc%" and friends. Remove
4763 Declare read_one_sym() at top of file.
4764 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
4765 MC68WRMAGIC can have the same value without causing a duplicate
4768 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
4770 * Allow a Makefile to be built without building the
4771 tm and xm file links that screw up builds in subdirectories.
4772 This is done with `config.gdb none', then you can do things
4773 like `make gdb.tar.Z'.
4774 * tconfig/none: Config file for no target system
4775 * xconfig/none: Config file for no host system
4776 * config.gdb: If no TM or XM files are called out by the
4777 host or target file, don't make links for them.
4779 * cplus-dem.c: Add documentation.
4781 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
4782 simple error, so the user's gdb doesn't crash due to some object
4783 file problem (e.g. somebody is rebuilding the file out from under
4786 * printcmd.c (print_address_symbolic): demangle the symbol.
4788 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
4789 Motorola copyrights in it. Make "make gdb.tar.Z" work.
4790 (alldeps.mak): sort and uniq all results from this; duplicates
4791 hose gdb.tar.Z link building. Remove RCS files from
4792 tconfig and xconfig. Add config files for sun386. Add
4793 a few odd files to OTHERS and HFILES.
4795 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
4797 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
4798 Roll version number to 3.91.5. Make lint work in bindir.
4800 * README: Document cross-debugging and new file structure.
4802 * blockframe.c: Lint. Include "value.h" to declare read_register.
4803 (find_pc_partial_function): remove duplicate line.
4805 * command.h: Lint. Declare error_no_arg and dont_repeat.
4807 * tm-news.h: Remove inadvertently duplicated stuff.
4809 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
4810 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
4812 * config.gdb: Allow `config.gdb host target' form. Clean
4813 up previous change that printed bogus messages when you just said
4816 * core.c: #include "command.h" for lint.
4819 * main.c: Remove some casts of enums. Lint.
4826 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
4828 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
4829 read it from memory. This will allow us to save ptrace calls
4830 eventually. Changed caller single_step too.
4832 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
4833 that we aren't going to use, saving many ptrace calls, especially
4834 when watchpointing or single stepping. Use some #define's for
4836 (store_inferior_registers): Ditto.
4837 (core_file_command): Use some #define's for constants.
4839 * tm-sparc.h: Add #define's for some register numbers, so we
4840 can eliminate the use of random constants in sparc-xdep.c.
4842 * stack.c (frame_command, print_frame_info, up_command,
4843 down_command) Remove frame_changed, since it
4844 causes a bug and doesn't seem to do anything useful. In some
4845 places it was used as a flag, in others as a stack level (?).
4847 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
4848 default is to use the portable (vprintf) version rather than the
4850 * xm-news.h (MISSING_VPRINTF): Add.
4852 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
4854 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
4856 * Remove stuff that forces -Bstatic linking of gdb, and warnings
4857 about linking debugged programs -Bstatic in the sun?os4 config
4858 files in tconfig and xconfig subdirectories.
4860 * main.c (main): Remove unreached exit(0) now that we exit
4863 * Create TODO file for online bug list. There are too many
4864 "little" bugs to keep track of on paper.
4866 * Change Projects file to refer to bug-gdb@cygnus.com
4867 rather than kingdon@ai.
4869 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
4871 * Makefile.dist (VERSION): 3.91.4 now.
4873 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
4874 (condense_misc_bunches): Add sanity check that misc_count is
4875 the same as the number of symbols in the bunch.
4877 * coffread.c: rename init_misc_bunches. Pass an argument
4878 to condense_misc_bunches (a zero).
4880 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
4881 every time we are called; don't rely on our caller to do it.
4882 (add_file): Remove call to init_misc_bunches.
4884 * mipsread.c: Only warn, don't error, if unknown symbol types.
4885 This keeps an old gdb from falling on its face if it sees newly
4886 extended symbol info. Rename init_misc_bunches.
4888 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
4890 * Merge in changes from Per Bothner for DECstations and other
4891 MIPS stuff. The rest is Bothner speaking:
4893 The next message is a merger of Alessando Forin's mips port with
4894 mine. I've tried to use my good if biased judgment to get
4895 the best of both. It *does* need testing.
4897 Some of the changes are general, *not* mips-specific.
4900 Didn't believe in little-endian bit order.
4901 There are still inconsistencies about whether flags
4902 like BITS_BIG_ENDIAN are integer (#if ...) or
4903 boolean (#ifdef ...). I tried to paper over them.
4905 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
4906 Moved some misc_function code that was common to
4907 {dbx,coff,mips}read.c to symtab.c.
4908 In the process, I think I cleaned things up a bit.
4909 At the same time, moved obsavestring and obconcat to symtab.c.
4912 Removed obsolete condense_addl_misc_bunches (use
4913 condense_misc_bunches(1) instead).
4916 Needed to include <sys/dir>, at least on DECstations.
4918 valops.c, mips-tdep.c, tm-mips.h:
4919 Added PUSH_ARGUMENTS macro to support funny argument-pushing
4920 conventions (when STACK_ALIGN is insufficient).
4921 Needed on mips, where doubles need 8-byte alignment,
4922 but ints only need 4.
4925 Removed cruft that was not being used.
4926 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
4929 Print $ before register-names (I think that makes things a little
4931 Never print two instructions, even if one delays.
4932 Removed hex-disassemble set_cmd. (This is not mips-specific,
4933 so I think the argument is whether it is generally worthwhile or not.
4934 I'm inclined to think not, given how easy it is to
4935 convert between radixes in gdb.)
4938 This is basically Alessando's code.
4939 It doesn't use obstacks; I changed it to use obstacks
4940 in a few minor places where using malloc causes a
4941 memory leak. (Probably, more places could/should be changed.)
4942 I added record_misc_function where it was missing.
4943 In symbol_file_command and add_file_command, I tried
4944 to make the code consistent with more recent versions.
4945 Minor sylistic changes in parse_procedure.
4946 Make a .gdbinfo. psuedo-symbol point back to the real
4947 procedure symbol (using the isym field).
4950 This is basically from my port, but with a lot of details
4951 and a number of routines merged in from Alessando's version.
4952 I basically used my code "raw" backtrace (use heuristics
4953 from the actual code, rather than symbol table info) - though
4954 the idea is Alessandro's. I feel my code is a little cleaner
4955 here, particularly in being a little more flexible, such as being
4956 able to handle gcc-produced code (which it now can).
4957 It also doesn't do frame caching (which is not useful
4958 more recent gdb versions).
4959 I also used my code for push_/pop_dummy, more or less.
4960 I tried to incorporate AF's code for testing sigtramp
4961 while backtracing; I probably got it wrong.
4962 Added mips_print_register, which tries to scrunch as much
4963 information as possible on a screen...
4964 Removed the skip-prologue set_cmd. As with hex-disassemble (see
4965 under mips-pinsn.c), I don't see anything mips-specific here,
4966 and I don't see it being all that useful anyway.
4969 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
4970 Use more register names (rather than hard-cases numbers).
4972 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
4974 * Hack up 3.90.11 changes:
4976 * Makefile.dist (depend): parameterize $(GCC).
4977 Add solib.c and solib.o.
4978 (readline): Fix vpath for both absolute or relative SRCDIR.
4980 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
4981 Also, let the part I didn't understand at least compile so
4982 I can test the rest. FIXME.
4984 * dbxread.c: Fix thinko using strcmp.
4985 (init_psymbol_list): declare static.
4986 (partial_symbol_file_open): Comment cleanups better, avoid
4987 cleaning up the string table since the caller will do that.
4988 Move the stat for mod time into symbol_file_command, temporarily.
4989 (There should be a mod time for each symbol file, eventually,
4990 to control its rereading. FIXME.)
4992 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
4993 SunOS, which gives error for shared libs otherwise. (From
4994 Schaefer, probably FIXME needs work for portability.)
4996 * solib.c: Move #include "param.h" to work.
4997 Lowercase all the Uppercase Letters In the Messages.
4998 (find_solib): Clean up inferior_so_name for debug printouts.
4999 Allow no argument, to mean all shared libraries.
5001 * symmisc.c: include param.h to get CLEAR_SOLIB.
5003 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5005 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5006 to 3.90.11. ChangeLog entries below are from this.
5008 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5012 * Makefile.dist (HFILES): Add tm-sunos.h.
5014 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5018 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5020 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5022 * sparc-opcode.h Added single-operand version of rett.
5024 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5026 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5027 Put parens around gcc_p in expansion.
5029 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5031 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5033 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5035 * Changes for Sun shared libraries:
5036 blockframe.c (find_pc_partial_function): If a non-text symbol
5037 is found, set *address = pc - FUNCTION_START_OFFSET.
5038 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5039 Disable breakpoints instead of giving an error.
5040 source.c (select_source_symtab): Initialize cs_pst.
5041 symmisc.c: Call CLEAR_SOLIB if defined.
5042 symtab.h: Make text{low,high} CORE_ADDR not int.
5043 (psymtab): New field addr.
5045 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5046 (record_misc_function): Give correct type for N_DATA symbols.
5047 (condense_misc_bunches): do "misc_function_count = j" regardless
5049 Take code which is shared between symbol_file_command and
5050 add_file_command and put it into partial_symbol_file_{open,read}.
5051 Split add_file_command into add_file_command and add_file.
5052 Make psymtab_to_symtab read in the string table if the file
5054 Two new parameters to read_dbx_symtab and start_psymtab.
5055 tm-sunos.h: New file.
5057 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5059 * infcmd.c: Change cont_command to continue_command and "cont"
5062 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5064 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5066 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5068 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5069 size 1,2,4,8 rather than size < 8.
5071 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5072 as necessary, not just once.
5074 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5076 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5078 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5080 * tm-news.h: Add CALL_DUMMY_*.
5082 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5084 * config.gdb: In list_host, list_target, use ${i}, not $i.
5086 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5088 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5090 * sparc-opcode.h: Change all store floating-point state register
5091 instructions to have the right match & lose fields.
5093 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5095 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5097 config.gdb: If srcdir != ., create readline directory and
5098 copy a makefile into it.
5100 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5101 consistency with POSIX.
5103 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5104 when we exit its exp_valid_block.
5106 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5108 * Makefile.dist: Bump version to 3.91.3.
5110 * Clean up handling of breakpoint commands (somewhat).
5111 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5113 inferior.h: Add breakpoint_proceeded to inferior status struct
5114 and globals; save it and restore it.
5115 (clear_breakpoint_commands): Cleanup, remove old #define.
5117 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5118 (save_inferior_status, restore_inferior_status): handle it also.
5119 (proceed): Remove earlier code that set breakpoint_proceeded.
5120 It is now set only in clear_proceed_status.
5121 (clear_proceed_status): Cleanup, use bpstat_clear rather
5122 than clear_breakpoint_commands. No callers need the stop_bpstat
5123 between clear_proceed_status and proceed.
5125 infcmd.c: Add breakpoint_proceeded definition and comment.
5126 (cont_command, jump_command, signal_command): Move call to
5127 clear_proceed_status right next to call to proceed.
5129 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5130 caller's argument while running down the chain of breakpoints.
5131 Use new variable "breakpoint_proceeded" to determine when
5132 a command that it executes moves the inferior past the
5134 (bpstat_clear): Handle NULL argument.
5135 (bpstat_clear_actions): Avoid useless call to
5136 breakpoint_auto_delete.
5137 (delete_breakpoint): Clean up bpstat's that are pointing to
5138 the deleted breakpoint from the stop_bpstat chain.
5139 (breakpoint_auto_delete): Simplify.
5141 * Clean up handling of EOF, error on stdin, etc. This was
5142 prompted by a network problem that caused gdb to go into an
5143 infinite loop filling up its malloc'd memory.
5145 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5146 not clear_breakpoints_commands, which is now gone.
5147 (main): If command_loop returns (e.g. from EOF on stdin), do
5148 a quit_command (looping back to command_loop if quit_command
5149 doesn't really quit).
5150 (command_loop): check result from command_line_input and
5151 exit if it returns NULL, rather than passing the NULL to
5153 (gdb_readline): Free malloc'd result space before returning
5156 * utils.c (query): Handle C-d to mean "yes", just as if the
5157 input was not a terminal. Also avoid infinite loop if EOF
5158 occurs in mid-input-line before newline. This allows
5159 query to be used at EOF on stdin with reasonable results.
5161 * infrun.c (proceed): Set breakpoint_proceeded.
5163 * values.c (value_as_long): Avoid infinite recursion for enums.
5164 (_initialize_values): Fix typo in help msg (kingdon).
5166 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5167 RL_LIB for linking. This allows -lreadline for linking
5168 and nothing for dependencies, once readline is a real library.
5170 * config.gdb: Jim Kingdon: give useful error message if the
5171 host or target type is not recognized.
5173 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5174 it just defines it. Dumb, but deal with it.
5176 * Jim Kingdon suggests:
5177 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5179 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5181 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5183 * Clean up Bothner's changes.
5185 * blockframe.c (clear_pc_function_cache): New function.
5186 * blockframe.c: remake cache_pc_function_* static.
5187 * dbxread.c (symbol_file_command): remove references to
5188 cache_pc_function_* variables.
5189 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5190 * printcmd.c: Avoid kludging a global variable (addressprint)
5191 to avoid printing the address of a string twice. Instead,
5192 pass the format letter 's' down low enough that it can be seen
5193 to avoid this problem.
5194 (print_formatted): Pass format arg to value_print.
5195 (restore_addressprint): Remove function.
5196 (do_examine): Avoid hacking addressprint, cleanups and such.
5197 (print_frame_args): Add a comment to a Bothner change.
5198 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5199 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5200 to wipe out the values cached in blockframe.c.
5201 * symtab.c (find_method): Add comment saying how big you must
5202 allocate to be "big enough". Per being terse again.
5203 * valprint.c (val_print): Handle format letter "s" to print
5204 strings without addresses. Add comment to vtbl printing code
5205 which casts with wild abandon. Rearrange reference-printing
5207 @0xaddr: value (print w/addressprint)
5208 value (print w/~addressprint)
5209 @0xaddr (parameter lists w/addressprint)
5210 or nothing (parameter lists w/o addressprint)
5212 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5214 * Merge more changes from Per Bothner:
5216 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5217 annoying) that I tried to improve it. Here are my suggestions.
5219 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5222 Do automatic de-reference when taking the address of a reference.
5224 Don't deref_ref when printing parameter lists.
5226 More attempts at treating refernences properly.
5228 In val_print, if deref_ref==0, don't print dangling " = ".
5230 Add COERCE_REF macro, which de-references an REF.
5232 * Merge changes from Per Bothner:
5234 * Fixed (Sony news)-specific configuration problems.
5235 * Fixed other problems with using vanilla pcc and libc (enum problems;
5236 assumption that vsprintf exists).
5237 * Some major speed-ups (finc_pc_partial_function now caches a match;
5238 parsing avoids duplicate symbol_lookup calls).
5239 * Changed handling of baseclasses (no longer use baseclasses field
5240 of struct type, use the first n_baseclasses fields instead).
5241 * Various minor changes/fixes, most C++-related.
5244 Cache the most previous match from find_pc_partial_function.
5245 (Save both low and high ends of matching function's pc range.)
5246 This speeds up the loop of infrun.c:wait_for_inferior quite
5247 a bit, and makes step/next commands much zippier.
5249 Added an enum->int cast (otherwise, some compilers barf).
5251 No longer set baseclass offset to 0, since multiple
5252 inheritance now mostly works.
5253 Added a number of casts, to shut up compiler warnings
5254 (after stabs where made enums, not ints).
5255 When discarding a symbol table (in symbol_file_command),
5256 must clear the cache introduced in blockframe.c.
5257 Don't convert $vtbl_ptr_type to vtbl any more.
5258 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5259 Mask off sign bit emitted by g++ for virtual table offset.
5260 Set voffset to -1 (not 1) for static member functions.
5262 Changed parsing/lexing of names to avoid doing symbol lookup twice
5263 (once when lexing to determine symbol class, once for real).
5264 Now only call symbol_lookup once. Fields of 'this' win especially big.
5266 Subpress printing addr twice in the case of 'x/s addr'.
5268 lookup_basetype_type is no longer used.
5269 Add find_methods as recursive helper function to decode_line_1.
5270 This allows multiple inheritance to work.
5271 Also, once one or more matches has been found, do not look in
5272 base-classes. (Baseclass methods would be overridden, anyway.)
5274 Removed baseclasses array in struct type.
5275 Instead of using baseclasses[i], use fields[i-1].
5276 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5277 Changed sign convention of voffset (previous was inconsistent).
5279 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5281 Used to assume existence of vsprintf. Re-written to not need it
5282 if HAVE_VPRINTF is undefined.
5284 typecmp was too pessimistic. Made it less so.
5286 Don't print space after address.
5287 If vtable points to a misc symbol (with 0 offset), print it,
5288 since that indicates the actual class of the object.
5289 Changed ype_print_derivation_info to use new inheritance
5290 scheme (without baseclasses vector).
5292 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5293 Also, changes needed because TYPE_BASECLASSES were removed.
5295 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5297 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5300 If there is no path set, and the symbols don't indicate what directory
5301 a file was compiled in, look in the current directory. But either
5302 a path or a known compilation directory will prevent this.
5305 Three independent bug fixes:
5306 * Remove the #if 0 block that breaks some stuff.
5307 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5308 adapt gdb to either SunOS 4.0.* or 4.1.
5309 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5312 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5315 (type_print) Demangle the name being printed.
5316 (type_print_base) Handle botched demangling without coredump (tiemann).
5319 (check_stub_method): Document routine.
5320 (tiemann) fix bug for no-arg functions
5321 Avoid clobbering beyond end of malloc'd storage.
5322 Terminate the argument list properly.
5324 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5326 * Changes merged by John Gilmore:
5329 In breakpoint_1, use new print_address_symbolic instead
5330 of find_pc_partial_function. (This forces use of assembler-level
5331 addresses, and avoids misleading non-mangled source-level names.)
5333 Generalize ansi argument such that -1 means skip arglist totally.
5334 Removed global variable print_ansi_qualifiers (which made
5335 code non-reentrant), in favor of extra explicit arguments
5336 to internal routines.
5338 Add new helper function print_address_symbolic.
5339 Use find_pc_misc_function instead of find_pc_partial_function
5340 (since we want assembler-level symbols here).
5342 Print unknown function as just "f (...)", not "f (...) (...)".
5343 Use new fputs_demangled explicitly.
5345 Fixed a typing violation (problem: value.h cannot be imported
5346 without renaming many variable in this file).
5347 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5348 decode_line_1: Moved forward some never-reached code.
5349 Made decode_line_2 skip function prologues correctly.
5351 fputs_filtered should not demangle by default.
5352 Add new fputs_demangled to demangle on demand..
5354 Change value_struct_elt to use value_primitive_field (using recursive
5355 utility function search_struct_field). This allows foo.bar to work
5356 for multiple inheritance (so far only for data fields).
5357 Change check_field in the same way (recursive helper function
5358 to support multiple inheritance).
5359 (Note: there are more of these problems that I haven't fixed.
5360 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5361 value_of_this: 'this' symbol name is now just "this", note "$this".
5363 Don't print static members.
5364 Avoid printing "members of <type>" if there are none.
5365 Simplified type_print_derivation_info by merging duplicate code.
5366 Remove useless blank lines in type_print_base (ptype command).
5368 Added declaration of new routine value_primitive_field.
5370 Added value_primitive_field which is generalized version of
5371 value_field that can handle multiple inheritance (non-zero offsets etc).
5372 Re-implemented value_field to call value_primitive_field.
5374 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
5376 * infcmd.c -- insert else to avoid 'delete env' coredump when you
5377 delete the whole environment. Karl Berry reported the bug.
5378 * source.c - fix openp to avoid //'s in filenames, which
5379 trigger an Emacs bug causing it to not be able to find files
5380 when running gdb in a window.
5381 * dbxread.c - zap the #if 0 that botches the add-file code.
5382 It seems to work a lot better without all the code commented out.
5384 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
5386 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
5389 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
5391 * Makefile - added a ${CFLAGS} to a couple of entries,
5392 added remote-sa.sparc.c
5393 * added remote.sa-sparc.c, a modification of remote.c
5394 which conducts a dialog directly with the SparcStation prom.
5395 * breakpoint.c, infrun.c, sparcdep.c added
5396 remote_insert_breakpoint(), and remote_remove_breakpoint()
5397 to breakpoint.c instead of directly writing breakpoint instructions.
5398 * sparcdep.c on remote_debugging,there is no need
5399 to remove signle step breakpoint instructions.
5400 * main.c added "-epoch" flag and "int epoch_interface" to main.c
5402 * printcmd.c - epoch interface sends lisp expressions to open up
5403 epoch windows on inspection.
5404 * valprint.c - added arrayprint, and addressprint and made adding
5405 format controls easier
5406 * wait.h added a couple of undef's because we were getting
5407 complaints about WSTOPSIG and WTERMSIG begin redefined.
5410 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
5412 * symtab.c (decode_line_1): Add support for handling method stubs
5413 in the type information.
5415 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
5417 * values.c (baseclass_addr): Run loop from INDEX+1 to
5418 N_BASECLASSES; otherwise, we can still get into a loop.
5419 @@ This should be restructured to use a cleaner search strategy.
5421 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
5423 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
5424 abbreviation "Tt" for tags which have the same name as their
5427 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
5429 * symtab.c (list_symbols): add ability to set breakpoints on all
5430 the functions which match a particular regular expression.
5432 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
5434 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
5435 should print ANSI qualifiers (such as `const' and `volatile').
5436 All callers changed to call with ANSI == 1, except from
5437 `check_method_stub', which uses old-style syntax.
5439 * symseg.h (struct fn_field): Remove unneccessary `args' field.
5440 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
5442 * values.c (check_stub_method): New function.
5444 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
5446 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
5447 * valprint (type_print_base): Ditto.
5449 * symtab.c (gdb_mangle_typename): New function.
5451 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
5453 * breakpoint.c (catch_command): New function. Provides a
5454 mechanism to set breakpoints based on catch clauses.
5455 (disable_catch): Similar, but disables breakpoints on catch
5457 (delete_catch): Similar, but deleted breakpoints on catch clauses.
5459 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
5461 * blockframe.c (blockvector_for_pc): New function.
5462 * blockframe.c (block_for_pc): Changed to call
5463 `blockvector_for_pc' and get the block itself.
5465 * stack.c (catch_info): New function. Prints info about
5466 exceptions which can be caught in the current frame.
5467 * stack.c (print_frame_label_vars): New function. Similar to
5468 `print_frame_local_vars'.
5469 * stack.c (print_block_frame_labels): Prints out labels that are
5470 defined in this frame. These labels are exceptions that can be
5473 * dbxread.c: Updated to handle N_CATCH symtab types.
5475 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
5477 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
5478 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
5479 when printing the type.
