1 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
3 * .gdbinit: Move 'set complaints' to top, so it runs even in
4 case we aren't debugging GDB.
5 * language.c (_initialize_language): Fix type check and range
6 check documentation strings.
7 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
8 language.c can use it. (Though language.c should really not be
9 handling warnings/errors the way it does, FIXME.)
10 * symtab.c (lookup_primitive_type): const lint.
12 Bugfix from Peter Schauer:
13 * source.c (lines_to_list): Make signed, to avoid comparison
14 going unsigned and complaining that -3 is too high for 21 lines.
15 * stack.c (lines_to_list): Ditto.
17 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
19 * Makefile.in (HFILES): Add minimon.h.
20 (VERSION): Roll version number to 4.0.95.
21 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
22 New rules for building distributions. Normal distribution
23 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
24 one level up from here; it calls make-proto-gdb.dir to build a
25 directory `proto-gdb' which is an image of the release. The old
26 `gdb.tar.Z' rule still works too.
27 * config.sub, configure: Roll in latest from ..
29 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
31 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
32 new-target, and new-config chapters; fix minor typos; come closer
33 to usual GNU markup conventions for @file @samp @code @var.
35 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
37 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
38 * mipsread.c (parse_partial_symbols): Enter the name of all
39 structs/unions... into the psymtab so we can access them if the
40 symtab is not read in.
41 * mips-tdep.c: Remove some unneded (?) #includes.
42 * xconfig/dec3100: Add HAVE_STRSTR.
44 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
46 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
47 * c-exp.y, m2-exp.y: Lint.
48 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
49 * valprint.c (val_print_fields): Check for stub type.
50 * mipsread.c (_initialize_mipsread): Avoid using
51 builtin_type_void at initialize time.
52 (mipscoff_symfile_read): use it now.
54 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
56 Merge multiple-language support, and partial Modula-2 support,
57 from Andrew Beers <beers@cs.buffalo.edu>.
59 * i387-tdep.c: New file, consolidates most 80387 support,
60 and eliminates host dependency on double<->extended conversions.
61 * i386-xdep.c, symm-xdep.c: Remove most 387 support.

74 (read_dbx_symtab, case N_DEFD): Ignore.
75 (read_enum_type): Recognize FALSE/TRUE enum as Modula-2 BOOLEAN.
76 (read_range_type): Rename MAX_OF_TYPE to MAX_OF_C_TYPE, etc.
77 #if 0 out its uses, though, since they set a dead value.
78 * coffread.c (end_symtab): Use allocate_symtab.
79 (process_coff_symbol): #if 0'd for functions and params as above.
80 (read_enum_type): Recognize Modula-2 BOOLEAN.
81 * symtab.c (add_param_to_type): #if 0'd function to add a
82 parameter type to a function type's field list.

154 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
156 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
157 entries are enclosed herein:
159 Mon Jun 3 17:05:45 EDT 1991
161 m2-exp.y Created. Tested outside of GDB for a few days. Proper
162 operators were added, C specific operators and tokens
163 removed. yylex() revamped to some extent. Still things
164 missing from the grammar, such as sets.
165 Tested for two weeks in GDB v3.5.
167 Tue Jun 11 17:23:48 EDT 1991
169 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
170 so they are built-in. Sort of a hack.
172 Fri Jun 14 12:53:51 EDT 1991
174 m2-exp.y Added range checking for numeric constants. Any numeric
175 constant is assumed to be of builtin type INTEGER unless:
176 (1) it is octal or hexadecimal, in which case it is a
177 CARDINAL; (2) it is too big to fit into an INTEGER, in
178 which case it is a CARDINAL.
179 eval.c Added simple range checking for +, -, and * on integers.
180 Doesn't work very well for *, since 6 * 1,000,000,000 =
181 1,705,032,704, which fails the simple test of result >=
182 first_operand, no matter in what order the operands are.
184 Tue Jun 18 14:11:30 EDT 1991
186 Broke the parser into parts, one containing the C grammar and the other
187 containing code to be shared by all of the grammars.
189 The following files no longer exist:
194 The following files were added:
196 c-exp.y (The C grammar)
197 m2-exp.y (The Modula-2 grammar)
198 parser-code.c (Code that is shared by the above grammar)
202 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
203 now necessary to use the Bison compiler compiler, since it
204 will generate function/variable prefixes other than yy.
206 Tue Jun 18 16:47:49 EDT 1991
208 symtab.[ch] Added the external variable working_lang, than holds the
209 value of the current working language.
210 Added the ennumerated type language_mode, with the values
211 language_auto and language_manual, the former meaning that
212 GDB sets working_lang as needed, and the latter meaning
213 that the value of working_lang is totally under user
215 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
216 REAL, BOOLEAN and CHAR. Also added the type codes
217 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
218 utils.c Added set_language_command and show_language_command to
219 implement the GDB support commands "set language" and
221 expression.h A number of identifiers were added to the type exp_opcode
222 to facilitate Modula-2 builtin functions, integer
223 division, and array indexing.
225 Wed Jun 19 13:25:58 EDT 1991
227 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
228 if the language specified by working_lang requires the use
229 of strict typing of expressions. Eventually, even this
230 will be able to be changed by the user.
231 Added the macro RANGE_CHECK, which evaluates to non-zero
232 if the language specified by working_lang requires the
233 checking of a value against the domain of its type.
234 Eventually, even this will be able to be changed by the
236 language.[ch] Predicates involving types (simple_type, ordered_type,
237 same_type, integral_type, numeric_type, character_type,
238 boolean_type, float_type) are added. These predicates are
239 based on the current value of working_lang, and are handy
242 Wed Jun 19 15:39:34 EDT 1991
244 eval.c Added the function type_array_rank which computes the rank
246 valarith.c Added the funtion value_bool, which when given a integer
247 value.h value (ie. struct value *) as an argument, it returns a
248 boolean value (ie. struct value *) true if that integer
249 is non-zero, and a boolean value false otherwise.
250 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
251 will print out properly.
253 Wed Jun 19 16:36:34 EDT 1991
255 valops.c Added the function value_capitalize, which returns it
256 value.h argument capitalized if its argument is a lowercase
257 letter, or the argument unchanged if its argument is not a
259 valarith.c Added the function range_check_p, which returns non-zero
260 value.h if its value argument is between the integral bounds upper
262 Added the function range_check_enum_p, which makes sure
263 that its value argument is a valid member of the domain of
265 Added the function range_check_range_p, which makes sure
266 its value argument lies between the upper and lower bounds
267 of its type argument, which must be a ranged type.
268 Added the function check_array_index, which range and type
269 checks an index of an array.
270 Added the function value_multi_subscript, which computes
271 array[idx1,idx2...idxN], given a value array and an array
272 of values representing indicies.
273 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
274 unpack_long to work with TYPE_CODE_BOOL and
277 Wed Jun 19 18:04:08 EDT 1991
279 symtab.c Stored pervasive types in a structure and make
280 lookup_pervasive_type() a lookup function that was based
281 on working_lang. If lookup_pervasive_type() returned
282 non-zero, then that value was returned (a fix, since
283 before it simply wouldn't return the pervasive type.)
284 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
285 non-zero if the language specified by working_lang means
286 "conversion" when it says "cast".
287 valops.c Added the function value_real_cast(), which performs a
288 value.h *cast*, not a *conversion*, which is what value_cast()
289 does when it can. In particular,
290 value_cast(<float_type>,4) = 4.0, while
291 value_real_cast(<float_type>,4) = some mess.
292 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
293 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
294 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
295 and MIN on integral types. *NOTE*: These are currently
296 hardcoded to work only if there are 8 bits per storage
298 eval.c Made logical functions call value_bool to return a
299 properly typed boolean value, based on working_lang.
301 Thu Jun 20 11:55:27 EDT 1991
303 valprint.c Types now print out in a Modula-2 fashion. This works for
304 the cases when the type is printed out step-by-step, that
305 is, it doesn't work when the name of a structured type
306 (which includes the keyword "struct", etc.) is simply
308 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
309 since type specifications in C and Modula-2 are very
310 different. The C printing of a type is very recursive,
311 whereas in Modula-2 it is generally very simple. C has
312 type prefixes and suffixes, which have no real analogue in
313 Modula-2. Maybe type_print() should call a language
314 specific type printer. This is also advantageous if we
315 compile GDB to exclude some of the languages. We'll just
316 leave those functions out.
318 Thu Jun 20 16:57:10 EDT 1991
320 dbxread.c When reading the complete symbol table in (via
321 psymtab_to_symtab()), the number and types of function
322 arguments are added to a function type. define_symbol()
323 calls add_param_to_type() to accomplish this.
324 Assumption: when we come across a function definition
325 (N_FUN symbol with an 'f' or 'F' in the name), its
326 arguments will appear before another function definition.
327 When a function is found, a pointer to its type is placed
328 in the global in_function_type. Changes that
329 add_param_to_type() makes are to this global.
330 valprint.c The type of a function now includes (for Modula-2) the
331 types of its parameters.
332 eval.c Type checking and a check for the proper number of
333 arguments is now done for function calls. Not sure of the
334 impact this has on C++ member function yet.
336 Thu Jun 20 19:58:48 EDT 1991
338 valprint.c Rewrote the type printer. Broke it into two language
339 specific parts, adding the functions type_print_m2() and
341 An unfortunate consequence is this: if you debugging a C
342 program in Modula-2 mode (why?), info types does not work
343 well with regular expressions, since the types are printed
344 out in Modula-2 terminology, but stored in C terminology.
345 language.[ch] Added the functions new_type_last(), type_keyword(), and
346 type_sep() to aid in the printing of typedefs.
347 symtab.c Made the printing of typedefs as language independent as
348 possible through calls to new_type_last(), type_keyword(),
351 Fri Jun 21 11:50:26 EDT 1991
353 dbxread.c Check all incoming ennumerated types. If it looks like
354 Modula-2's BOOLEAN type, then change the type_code of the
355 type to TYPE_CODE_BOOL so we can process it as a boolean
357 valprint.c Replaced some of the 0x%x with calls to sprintf and
358 hexformat() in val_print().
359 language.[ch] Added the function hex_to_string(), which converts its
360 integral argument to a hexadecimal number (format is
361 language based) and returns the result as a string.
363 Mon Jun 24 12:25:07 EDT 1991
365 valprint.c Some functions call type_print_1() directly, instead of
366 value.h using type_print(), so they can specify where (column) to
367 print things. Since type_print() takes care of language
368 dependence, that needs to be called first. Added a
369 parameter depth to type_print() (so it is now like
370 type_print_1). Changed type_print to type_print_at, and
371 made type_print a macro that passes a depth argument of
373 symmisc.c Changed all calls to type_print_1 to calls to
375 Makefile.dist Made it possible to build GDB for a specific set of
376 depend languages. Do this by passing a definition for the macro
377 LANGS to make. LANGS should be a string containing a
378 space-separated list of language names (ie. LANGS="c m2").
379 The default is to build all languages. Note that grammar
380 files must follow the naming convention of <lang>-exp.y.
381 gdb.lang This holds the current value of the LANGS macro. It is
382 examined every time make is called, and is updated if
384 eval.c Added #ifdef _LANG_<lang> to these files.
385 expread.c Still need to add them to dbxread.c and coffread.c.
393 Mon Jun 24 16:33:11 EDT 1991
395 language.[ch] Added the functions hexformat_pre() and
396 hex_to_string_pre(), which take a prefix argument to
397 include in the format string. Thus, hexformat_pre("08") will
398 return "0x08x" (if the working language is language_c).
399 Made hexformat() and hex_to_string() calls to the above
400 with "" as the prefix argument.
402 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
403 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
404 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
405 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
406 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
407 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
408 valprint.c, vax-pinsn.c
410 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
411 calls to hexformat() and hex_to_string(). Format strings without
412 the leading "0x" were ignored.
414 depend Updated to take the above into account.
417 Tue Jun 25 15:27:18 EDT 1991
419 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
420 and type_check_t to keep track of the current state of
421 range and type checking.
422 main.c Added the variables range_mode, range_check, type_mode,
423 and type_check to record the current state of range and
424 type checking. Added initialization code to main().
425 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
429 Tue Jun 25 17:57:08 EDT 1991
431 dbxread.c process_one_symbol() updates the variable (enum language)
432 source_lang based on the extension of the filename
433 contained in the N_SO sybmol that started this symtab.
434 When end_symtab() is called, the value of source_lang is
435 put into the language field.
436 stack.c select_frame() sets working_lang (and possibly type_check
437 and range_check) to the language field of the symtab
438 associated with the frame that is selected if working_mode
439 is language_auto. If working_mode is language_manual, a
440 warning is printed and working_lang is not set.
441 language.c Added the function set_type_range(), which sets the value of
442 type_check and range_check (if their modes call for
443 automatic setting) based on the current value of
444 working_lang. A non-zero argument will cause the current
445 settings to be output.
448 Wed Jun 26 14:51:40 EDT 1991
450 eval.c Added range checks on assignment.
451 m2-exp.y Added the grammar for sets to the language. Currently,
452 these do not do anything except print an error message.
454 Wed Jun 26 17:01:04 EDT 1991
456 m2-exp.y Added the ability for parse_number() to parse negative
457 numbers. A global flag is set upon encountering a unary
458 minus. This was done to make, for example, 1 parse as a
459 CARDINAL, and not as an integer, per Wirth's examples in
460 Programming in Modula-2 ed.4.
461 valprint.c Added support for "set radix 2" by then setting
462 output_format to 't'.
463 eval.c Implemented range checking on subrange types. Added calls
464 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
465 Implemented MIN and MAX for ennumerated types. The
466 minimum value of an ennumerated type is defined by Wirth
467 as the first identifier, and the maximum as the last.
468 m2-exp.y Made octal numbers ending with "B" be characters and those
469 ending with "C" be numbers, per Wirth's book. (p. 34)
471 Thu Jun 27 14:11:52 EDT 1991
473 stack.c select_frame() now only sets working_lang, it does not
474 notify the user. If working_mode is language_manual, then
475 a warning is issued once.
476 main.c At the end of each call to execute_command(), working_lang
477 is checked against the local static (enum language)
478 current. If they differ and working_mode is
479 language_auto, the new settings of language, type and
480 range checking are printed out.
481 stack.c Modified frame_info() to include the language of the
482 current frame in the output of "info frame".
483 language.[ch] Added the function language_str() which returns the name
484 of the current language.
486 Fri Jun 28 15:33:14 EDT 1991
488 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
489 the language. INCL and DECL currently cause an error,
490 since sets are not implemented yet. INC and DEC are
491 implemented as PREINCREMENT/PREDECREMENT with one
492 argument, and as ASSIGN_MODIFY with two arguments.
493 eval.c Added type checking to the above cases.
494 value.h Added not_lval_constant to the lval_type ennumerated type.
495 not_lval_constant means that the value is a constant
496 value; that is 3 or 'a' or TRUE, not as in a constant
497 identifier. This is used to help coerce numbers such as 3
498 to either signed or unsigned numbers.
499 valops.c Added the function value_coerce_constants() which coerces
500 constant integers as following: if one is a constant and
501 the other is not, the constant's type is set to the type
502 of the other argument. If both are constants and one is
503 signed, the other is converted to a signed constant.
505 Sat Jun 29 17:26:29 EDT 1991
507 valarith.c Added a better range checker. It now checks range
508 (successfully) on integral operations [+-] (signed and
509 unsigned) for any C sized type. Still does not work well
511 int_in_size() returns an integer that is coerced to fit into
512 specified number of bytes.
514 Mon Jul 1 13:04:14 EDT 1991
516 language.[ch] Added the function binop_result_type(), which returns the
517 builtin (struct type *) type that would be the result of a
518 binop on the two values V1 and V2.
520 Wed Jul 3 19:22:53 EDT 1991
522 source.c Extended source_info() to include the source language in
523 the output from "info source".
525 Fri Jul 5 13:48:52 EDT 1991
527 utils.c Moved the support functions for the GDB set/show commands
528 dealing with language into language.c.
529 language.c Added the function language_info(), which displays info
530 about the current working language, type and range check
531 settings. Called via the GDB command "info language".
532 Added an initialization routine _initialize_language(),
533 that sets defaults for the language, type and range
534 variables and sets up the new GDB commands.
535 main.c Language setup moved to language.c.
538 Mon Jul 8 10:10:22 EDT 1991
540 valarith.c Debugged the range checker for arithmetic. Still does not
541 work for multiplication very well.
543 Mon Jul 8 12:40:37 EDT 1991
545 language.[ch] Added the function value_true() which returns non-zero if
546 its argument represents a boolean true value.
547 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
548 check the truth of an expression.
550 Thu Jul 11 12:51:34 EDT 1991
552 language.[ch] Added the predicate structured_type(), which returns
553 non-zero if the argument is a structured type.
554 Added the predicate pointer_type(), which returns non-zero
555 if the argument is a pointer type.
556 eval.c Added the ability to do addition and substraction on
557 pointers and integers. This case simply bypasses the
560 Thu Jul 11 14:41:42 EDT 1991
563 Added the symbol N_DEFD (0x4a) which is a definition
564 module dependency that is used by the GNU Modula-2
565 compiler and the linker. It is not important to GDB,
566 except that [dbx|coff|mips]read.c should ignore these
569 Fri Jul 12 16:07:00 EDT 1991
571 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
572 0 in val_print(). Also added statements to the else part
573 to coerce type (argument to val_print) to a pointer type
574 if it is an "array of unspecified length".
575 valops.c Added the function value_m2_string(), which returns a
576 (value) value which is a constant string, whose type is
577 (ARRAY [0..n] OF CHAR). The length field of the type
578 structure is set to zero, so it will be interpreted as an
579 "array of unspecified length".
580 stack.c Moved the language/frame mismatch check to
581 main.c:execute_command().
582 main.c The working language is recorded each time
583 execute_command() is executed. If working lang has
584 changed during its execution, then the new
585 language/type/range info is printed out for the user. If
586 the working language does not match the language of the
587 frame, a warning is issued.
589 Sat Jul 13 16:16:39 EDT 1991
591 eval.c Moved all the type-checking stuff for operators to
592 language.[ch] language.c. This is so we can keep language-specific
593 stuff (like for what type operators are defined) in
595 language.[ch] Added the function binop_type_check(), which checks to see
596 if its two (value) arguments are type-compatible with its
597 opcode argument. The opcode should represent an operation
598 involving an operator. Also added the macro function
599 unop_type_check, which calls binop_type_check with a
600 NULL second argument.
601 expprint.c Added Modula-2 operators to the op_print_tab, so info
602 expression.h break works correctly. Also added "op_string", which
603 returns the string corresponding to the (enum exp_opcode)
604 opcode that is its argument.
607 Sat Jul 13 18:26:18 EDT 1991
609 coffread.c Added code to record the type of function arguments with
610 each paricular function. Code is very similar to that
612 dbxread.c Moved add_param_to_type() to symtab.c
613 symtab.[ch] Added function add_param_to_type() from dbxread.c
615 *** NOTE: The above additions have not been tested.
617 Mon Jul 15 12:50:47 EDT 1991
619 langauge.[ch] Added the functions type_error and range_error, which work
620 like error() except if the type/range mode is set to
621 *_mode_warn, then they do not do a return_to_top_level(),
622 but merely print a warning.
623 Also changed [set|show]_[type|range]_command() to support
624 the new "warn" feature.
626 Thu Jul 18 17:50:54 EDT 1991
628 mipsread.c Added code to record the type of function arguments with
629 each particular function. Code is very similar to that
632 *** NOTE: The above additions have not been tested.
634 Fri Jul 19 11:19:10 EDT 1991
636 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
637 UMIN_OF_SIZE, which when given a size of a numeric type,
638 return the maximum and minimum value it can hold. UMAX...
639 and UMIN... return the result for unsigned types.
640 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
641 struct types. They call above macros.
642 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
643 avoid a name conlict with the above.
644 c-exp.y Added range checking on numeric constants in
645 parse_number() for completeness.
646 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
647 return 0 if working_lang is not language_c.
649 Thu Aug 8 14:17:22 EDT 1991
653 breakpoint.c Documentation strings of some commands changed to
654 eliminate the references to the C language where
657 Tue Aug 13 15:48:03 EDT 1991
659 m2-exp.y Added qualified identifiers to the grammar. The semantics
660 are slightly different from those of the GDB operator ::
662 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
663 type_exp, where type_exp is any valid type expression.
665 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
666 printcmd.c Modified ptype_command() so it actually parses the input
667 (necessary for type expressions with scope qualifiers).
668 Added the function ptype_eval() which expects an
669 expression composed of one OP_TYPE element.
670 *.[ch] Replaced all occurences of parse_c_expression with
672 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
674 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
676 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
678 Small fixes from Peter Schauer:
680 * infrun.c (child_attach): Lint.
681 * solib.c (find_solib): Handle shared libs version 2.
683 Small fixes from David Wood:
685 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
689 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
690 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
692 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
693 chars_per_line is at maximum (user typed `set width 0'). Fix
694 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
696 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
698 * coredep.c: include ptrace.h where necessary.
699 * mipsread.c(parse_lines): fix unsigned char problem that was
700 messing up line numbers on SGI's and possibly other MIPS based
702 * infrun.c (child_create_inferior): use better test to check
703 return val from setpgrp().
704 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
705 for sgi/irix support.
707 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
709 * mipsread.c (parse_symbol): Put non-static procedures
712 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
714 Patch together `text_start' and `text_end' for 29K port.
716 * exec.c (exec_command): If NEED_TEXT_START_END, define the
717 variables and set them based on the exec file.
718 * am29k-tdep.c: declare text_start.
719 * valops.c (call_function_by_hand): declare text_end.
721 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
722 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
723 because machines that do this will also have to know to
724 set NEED_TEXT_START_END. Besides, it was a redundant way to
726 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
727 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
730 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
732 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
734 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
735 Pass MUNCH_DEFINE to munch whenever we run it.
736 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
737 format string; use 0x%x instead.
738 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
739 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
740 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
741 * inflow.c: Handle `short' process group IDs.
742 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
743 and check for ptrace errors.
744 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
745 (coff_symfile_init): Initialize text_bfd_scnum.
746 (read_coff_symtab): Use it to find the text [and absolute?] sections.
747 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
748 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
749 Merge target arm case with other "easy" cases. Add target
750 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
751 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
753 * minimon.h, remote-adapt.c, remote-mm.c: Add.
754 * munch: Cope with RT/PC putting fns in data segment.
755 Restore ability to override `nm' by specifying MUNCH_NM.
756 * xconfig/rtbsd, xconfig/ultra3: New host systems.
757 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
758 and remote-adapt. Remove encapsulated coff #define's (the
759 support should go in BFD, and gdb shouldn't know or care).
760 * tconfig/a29k-kern: Same, but for remote kernel debugging.
761 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
762 * tm-29k.h: Update BADMAG (though it should go away).
763 Allow the register definitions to be overridden in another
764 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
765 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
766 DUMMY_SAVE_GR96, for handling kernel calling conventions
767 that use GR64+ rather than GR96+.
768 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
769 remote debugging of Ultra3 kernel. Includes tm-29k.h and
770 overrides various things.
772 * remote-mm.c (mm_attach, mm_wait): Handle attach like
773 child_attach does, making a clean stop in the newly attached
777 * coffread.c: Make coffread independent of any particular
778 variant of COFF. Avoid #include-ing any particular one except
779 internalcoff.h. BFD now passes key values for symbol reading
780 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
781 and the symbol masks and shifts); use them.
782 Remove obsolete end_of_text_addr.
784 * exec.c: Remove unused include files.
786 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
788 * Makefile.in (documentation targets): Pass $(M4).
789 Bugfix from eggert@twinsun.com (Paul Eggert).
791 * stack.c (down_silently_command): Check for stack existence.
793 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
795 * Makefile.in (VERSION): Update to 4.0.3.
797 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
799 * core.c (core_file_command): Print frame at coredump with
800 its level number, by calling print_stack_frame.
801 * frame.h: Add selected_frame_level, print_stack_frame.
802 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
803 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
804 Change print_sel_frame and print_selected_frame callers to
807 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
808 * symfile.c (free_named_symtabs): Ditto.
809 * main.c (main): wrap_here needs an arg.
810 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
811 (solib_add): Avoid noise.
812 (solib_create_inferior_hook): Lint.
813 (sharedlibrary_command): Move dont_repeat to here.
814 * utils.c (error): Call wrap_here to force buffered output.
816 Small patches from Peter Schauer:
818 * coffread.c (start_symtab): Free any existing line_vector before
820 (read_coff_symtab): Ditto for type_vector.
822 * source.c (lines_to_list): New variable, replacing function.
823 (all uses): Use as variable.
824 (_initialize_source): Add 'set listsize' and 'show listsize'.
825 * utils.c (lines_to_list): Remove function.
826 * stack.c (print_frame_info): Use as variable.
827 * defs.h (lines_to_list): Remove declaration.
829 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
831 * breakpoint.c (insert_breakpoints): Restore warning about
832 the program might be running in another process, but only for
833 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
834 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
836 * utils.c (error): if error_pre_print is set, print the string
838 * main.c (main, print_gnu_advertisement, print_gdb_version):
839 Reformat legalese so it always prints, but acts as an "I'm here"
840 message while symbols are being read. If any errors occur,
841 print a few newlines to set off the message and start it at the
842 left margin. Remove mention of "help" command, and don't yak
843 about symbol reading.
844 (catch_errors): Error string is now printed first in case of
846 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
847 suggest the "help" command.
849 * Makefile.in (VERSION): Set to 4.0.2.
851 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
853 * .gdbinit: Remove useless "rr" command. Set complaints
854 to 1 for people debugging gdb.
856 * breakpoint.c, remote-vx.c: Reword strings printed by
857 catch_errors callers.
859 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
861 * WHATS.NEW: "history write -> history save". Doc "write on/off".
862 (Fix from kenc@viewlogic.com.)
864 Fix some infrastructure to be able to cope with host and target
865 machines with different sized basic types (ints, ptrs, etc).
866 (Idea from pierre@la.tce.com (Pierre Willard).)
868 * values.c (value_from_longest): Rename from value_from_long.
869 Handle pointer types as well as integers, so that targets with
870 different pointer sizes from the host can be accomodated.
871 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
872 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
873 uses of value_from_long to value_from_longest.
874 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
875 the correct pointer type to value_from_long{est}.
877 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
879 * remote-vx.c: Remove obsolete code for calling functions via
880 vxworks kludge interface (it referenced value_from_long).
882 * valops.c (value_string): Find malloc with lookup_misc_func, not
885 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
887 Make writing to files work properly. (Fixes to BFD are also needed.)
889 * core.c (core_open): Open file ourselves, read or r/w, depending on
890 write_files. Use bfd_fdopenr.
891 * gdbcore.h (write_files): New variable.
892 * exec.c (write_files): Define variable, add set&show for it.
893 (exec_file_command): Use write_files to open for read or r/write.
895 Make shared library reading happen automatically. These changes
896 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
898 * inferior.h (stop_soon_quietly): Add to exported variables.
899 * infrun.c (child_create_inferior): call solib hook, if defined.
900 (child_attach): call solib hook, if defined.
901 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
902 (find_solib): Use lookup_misc_func rather than hand-rolled.
903 (symbol_add_stub): New stub for catch_errors.
904 (solib_add): Avoid output if !from_tty. Catch errors rather
905 than just calling symbol_file_add and bombing.
906 (solib_create_inferior_hook): Interface with the target process
907 to let it read and alloc shared libs, then figure out what it did.
909 * core.c (validate_files): Fix typo, soften warning.
910 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
912 * utils.c (fputs_demangled): Avoid duplicate printing if
913 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
915 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
916 (Fix from pierre@la.tce.com (Pierre Willard).)
918 * main.c (catch_errors): Change argument to a char * from an int,
919 since a char * can point to a struct full of glop, but an int
920 is not guaranteed to be able to hold a pointer.
921 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
922 breakpoint_re_set_one, breakpoint_re_set): Adapt.
923 * core.c (core_open, solib_add_stub): Adapt.
924 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
926 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
928 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
929 by adding .NOEXPORT target.
931 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
935 * Makefile.in (VERSION): Roll to 4.0.
936 (gdb.tar.Z): Make refcard.ps as well, for shipment.
938 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
940 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
943 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
946 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
948 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
949 reflect above name change
951 * WHATS.NEW: correct pointer to refcard.
953 * doc/gdb.texinfo: update New Features, Installing
955 * doc/gdbint.texinfo: add short description of configure +template
957 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
959 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
961 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
963 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
964 tar file, add dependencies for referenced doc files.
966 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
968 * coffread.c, symfile.c, stack.c: saberized.
970 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
972 * doc/refcard.tex: permuted Essential Commands sec
974 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
976 set/show symbol-reloading
977 default set complaints 0
979 RET-repeat disabled after prompted long displays
980 processID (attach) interpretation of 2nd GDB cmdline arg
982 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
984 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
985 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
986 breakpoint.c, main.c: lint.
988 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
990 Install new configuration scheme for GDB and friends.
992 * config.sub: Translate ordinary names to three-part names.
993 * configure: Use three-part names internally.
994 * configure.in: Translate three-part names to filenames.
996 * README, WHATS.NEW: Update for gdb-4.0.
997 * Makefile.in: Roll VERSION to 3.99.
999 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1001 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1002 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1003 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1004 to single structures rather than arrays; when passing
1005 their address, use &. This avoids trouble with bdead compilers.
1006 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1007 instead. This avoids portability headaches.
1008 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1010 * source.c (open_source_file): Avoid ANSI const bdeath by
1011 skipping declaration and then casting result value.
1012 * tm-hp300bsd.h: Clarify comment.
1013 * utils.c (strstr): Result is const char *; ANSI bdeath.
1014 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1015 since system include file defines it differently from "defs.h",
1016 though the two are equivalent for our purposes.
1017 * tconfig/hp300bsd: Add m68k-tdep.o.
1019 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1021 * tconfig/sun*4: Remove warnings about system assembler.
1023 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1025 * mcheck.c: Avoid warning about undeclared abort fn.
1026 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1027 it causes recursive calls to error() when used in cleanups.
1028 To do so requires that we make it a function, so we do.
1029 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1030 * utils.c (do_cleanups): Remove the current cleanup from the
1031 chain *before* calling it, in case error() is called from it.
1032 The result won't be pretty, but won't be an infinite loop either.
1034 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1036 * dbxread.c (read_struct_type): Grok anon structs for C++.
1037 (vb_name, vptr_name): Null terminate these strings.
1039 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1041 Minor bug fixes from BSD Net2 gdb:
1043 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1044 returns 0, there is no previous frame.
1045 * breakpoint.c (commands_command): If !from_tty, don't call
1046 input_from_terminal_p().
1047 * dbxread.c (record_misc_function): Speed up slightly.
1048 (compare_psymbols): Ditto.
1049 * infcmd.c (do_registers_info): Take a second argument to
1050 determine whether to print float registers. "info registers"
1051 does not do so anymore. "info all-registers" does, now.
1052 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1054 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1055 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1059 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1060 executing_breakpoint_commands if we are interrupted by error.
1061 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1062 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1063 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1064 catch_errors() so we can setup the frame regardless of whether
1065 the shared libs work.
1066 * ieee-float.c (double_to_ieee_extended): Get exponent from
1067 right place in little-endian systems. From John Carey.
1069 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1071 * main.c: Remove unused terminating_signals and catch_termination().
1072 (long_options): Terminate with a zero element.
1073 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1074 (gdb_readline): Make call-compatible with readline.
1075 (init_signals): Improve comments re vfork vs. signal.
1077 * utils.c (prompt_for_continue): Use new gdb_readline().
1078 If we prompt for continuation, we don't let CR repeat the previous
1079 command, once we get back to a prompt. It's too easy to keep
1080 hitting CR, expecting "--more--" prompts, and have some long
1081 command start repeating on you.
1083 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1085 * blockframe.c (frameless_look_for_prologue): Speed up by
1086 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1087 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1088 Define two variants, one faster.
1089 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1090 and return zero, rather than giving an error.
1091 (setup_arbitrary_frame): Initialize the PC in the new frame.
1092 (skip_prologue): Add a second arg saying whether we're just
1093 checking for a frameless function or not.
1095 * core.c (core_open, core_close, core_xfer_memory): Move
1096 section table pointers and bfd* into the target_ops.
1097 (core_open): Allow errors in shared lib reading, etc.
1098 (core_files_info): Describe shared library sections.
1100 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1101 exec_files_info, set_section_command): Move section table
1102 pointers and bfd* into the target_ops.
1103 (add_to_section_table): Add BFD to section table.
1105 * target.c (target_xfer_memory, target_info): Pass target to
1106 xfer_memory and target_info functions.
1109 * gdbcore.h: Move struct section_table.
1110 * target.h: New home of struct section_table.
1112 * solib.c (solib_add): New argument is the target_ops whose
1113 section list is to be added to, if any. Reallocate the
1114 sections in that target to add any that come from shared libs.
1115 (throughout) so_sections renamed to sections.
1116 (solib_xfer_memory): Deleted.
1117 * tm-sunos.h (SOLIB_ADD): Add target argument.
1118 (SOLIB_XFER_MEMORY): Delete.
1120 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1121 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1122 from target_ops. It's the same on all targets. Add two section
1123 pointers to target_ops.
1125 * stack.c (find_relative_frame): Dump ancient algorithm for
1126 "down", just use handy "next" pointers.
1127 (frame_command): Don't error if there is no stack; let user
1130 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1131 modifies static state in the parent process; new_tty itself
1132 runs in the child and modifies the child's file descriptors
1133 to match the saved static state.
1134 * infrun.c (child_create_inferior): Call new_tty_prefork,
1137 * infptrace.c (child_xfer_memory): Add ignored target arg.
1138 * remote-eb.c (eb_xfer_inferior_memory): ''
1139 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1140 * remote-vx.c (vx_xfer_memory): ''
1141 * remote.c (remote_xfer_memory): ''. Rename from
1142 remote_xfer_inferior_memory.
1144 * main.c (main): Only try to attach "corefile" argument if
1145 it starts with a digit.
1147 * symfile.c (symbol_reloading): New "set/show" variable.
1148 (symbol_file_add): Shorten message about symbol reading.
1149 (add_symbol_file_command): Merge with add_syms_addr_command,
1150 since this should work on all targets now.
1151 (stop_whining): Default to zero, to shut up complaints
1152 about bad symbol tables on many systems.
1153 (free_named_symtabs): Just exit unless symbol_reloading.
1155 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1156 and add comment explaining shared library screw.
1158 * source.c: #if defined => #ifdef.
1160 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1162 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1164 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1166 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1167 (doc/Makefile knows how to make one for local config)
1169 * Makefile.in: use doc/Makefile for doc targets
1171 * doc/Makefile: GDB documentation now has its own Makefile
1172 doc/refcard.tex: renamed from "gdbrc.tex"
1173 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1174 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1177 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1179 * values.c (baseclass_addr): When reading target memory, use the
1180 length of the basetype, not the upper type. We've only malloc'd
1181 enough space for the basetype, leading to errors in free().
1183 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1184 ends up as a function specially, since we know the actual type of
1185 the pointed-to address. This (somewhat) fixes display of
1186 expressions that include misc_function_vector names. Try `cond 1
1187 !strcmp("a","b")' then `i b'.
1189 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1190 The child can be proceeded from inside wait_for_inferior in
1191 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1192 getting skipped in that case.
1194 * expprint.c (print_subexp): Use filtered output, since the
1195 subroutines we call use it, otherwise the output is horribly
1196 mangled, since output of wrappable stuff comes out late.
1198 * Makefile.in: Bump VERSION to 3.98.1
1200 * infrun.c (child_create_process): Use execlp to find the
1201 shell to exec our target program. This requires some fiddling
1202 with `environ' since there is no execlpe().
1204 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1206 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1207 Minor rearrangement of refcard permits two new make targets--
1208 gdbrc.dvi DVI output for refcard, using CM fonts
1209 gdbrc.ps PostScript refcard, using PS fonts
1211 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1215 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1216 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1218 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1220 * doc/gdb.texinfo: last changes for release.
1221 Minor typo and formatting fixes; incorporated most fixes remaining from
1222 filed mail commenting on earlier drafts.
1224 Added warnings: pipes don't work in run command;
1225 conditions are converse of assertions;
1226 step over fn without debug info goes to next fn;
1227 vars may have "wrong" values near fn entrance, exit
1229 Added example from Kingston on printing repeated nonadjacent values
1231 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1232 shell mode for signals
1234 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1235 doesn't sound so much like its parent "Stopping and Continuing"; also
1236 moved entries on continue to top of section, so they don't get lost.
1238 Improved installation directions in appendix, added manual formatting
1241 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1243 * configure.in: Remove xm.h and tm.h even if we aren't linking
1244 new ones, so "./configure sun4; ./configure none" does the right
1245 thing. Assume that alldeps.mak and depend are already built in
1246 srcdir, and avoid running "make" (particularly "make depend",
1247 which involves "gcc") from inside configure. Build Makefile
1248 directly rather than building Makefile.conf first.
1249 * configure: Regenerate with above changes.
1250 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1251 to 3.98. Revise gdb.tar.Z procedure to produce a file
1252 called gdb-$(VERSION).tar.Z but which unpacks into a
1253 directory called "gdb". Move non-source files out of
1254 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1255 (depend): Don't try to do "gcc expread.y".
1256 (expread.o): Update dependencies by hand.
1258 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1261 Fixed a variety of small typos that prevented info from formatting
1262 cleanly; altered too-long heading for GPL Appendix, as discussed
1263 w/RMS; Changed date on cover to July 91.
1265 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1268 (1) Applied some fixes due to comments from Larry Breed (easier ones
1269 through chapsec 5.2)
1270 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1271 it's broken in latest texinfo
1272 (3) Introduced *some* use of [] for optional arguments, where
1273 explanation is not simpler by listing cmd w arg and cmd w/out arg
1274 separately. Still not using @deffn.
1275 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1276 couple of headings are too long. Need patches to texinfo or revision
1279 * Partial update to README (which still needs work for this
1280 release!): (1) use of configure corrected for new script,
1281 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1283 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1285 * symtab.c (lookup_symbol): Don't complain right off about
1286 no debug symbols; use the misc function vector first.
1287 (list_symbols): Use misc function vector to find symbols
1288 that don't have debug info, and print them.
1289 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1290 PC range doesn't match symtab PC range, as it does on the
1291 MIPS because our symtab reading isn't perfect.
1293 * dbxread.c (dbx_symfile_read): Make warning about
1294 "no debug symbols" slightly nicer.
1296 * source.c (select_source_symtab): If "main" symbol exists,
1297 but decode_line_spec can't find line info, don't just return
1298 a zero; try other source symtabs or give an error.
1300 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1301 their low addresses first, then rip through fixing high addrs.
1303 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1304 <runene@ifi.uio.no>.
1305 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1307 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1309 * Minor, mostly mechanical, cleanup of doc subdir for clean
1310 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1311 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1313 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
1315 Mostly MIPS and general symbol-reading fixups.
1317 * doc/gdbint.texinfo: Add documentation on symbol-reading
1320 * mipsread.c: Remove kludges around #include "ecoff.h".
1321 Remove redefinitions of a_magic, etc, no longer used.
1322 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
1323 Fix global overview comments to match symfile.c protocol.
1324 (mipscoff_new_init): Eliminate cur_hdr if we have one.
1325 (mipscoff_symfile_read): Eliminate unused code. Avoid
1326 sorting all the symtabs, when all we have read here is psymtabs.
1327 The symtabs are sorted as they are created anyway. Tell
1328 condense_misc_bunches whether we're mainline.
1329 (psymtab_to_symtab_1): Pass filename when recursing, to make
1330 stack trace more informative.
1331 (parse_partial_symbols): Assume cur_hdr as argument.
1332 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
1333 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
1334 the TYPE_NAME of char *, since that's done in symfile.c.
1335 (free_numargs, parse_symbol, add_symbol, add_block,
1336 shrink_linetable): Declare these fns void.
1337 (upgrade_type): Convert tree of if's to switch. Clean up
1338 bogus "off == 0" handling with a complaint. Avoid setting
1339 field bitpos and bitsize of array with lower and upper bounds.
1340 Check specified bitsize of elements against their actual type's
1341 bitsize, and complain if different. Complain about unknown
1343 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
1344 (psymtab_to_symtab_1): Print names of subsidiary files that
1345 are being read in. FIXME, we read far too many files. This code
1346 is not the problem, the problem is in parse_fdr where the psymtabs
1348 (cross_ref): Result should indicate that we used one aux entry
1349 normally, or two if we encountered a "next" entry. This used
1350 to leave the caller pointing at the wrong aux entry.
1351 (add_symbol): If overflowed cur_block, reallocate it larger,
1352 chase all pointers to it, and complain(), rather than clobber memory.
1353 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
1354 (new_field): Only allocate one field initially, not two.
1355 Pull ++ out of macro argument. Simplify.
1356 (_initialize_mipsread): Avoid initialization of importd
1357 global_psymbols and static_psymbols.
1359 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
1360 to properly set pst->symtab; avoid searching for it.
1361 (symfile_fns): Improve comments, add a FIXME.
1362 * dbxread.c: Update comments to reflect symfile protocol.
1363 (read_ofile_symtab, end_symtab): Return the symtab.
1364 (psymtab_to_symtab_1): Set pst->symtab.
1366 * coffread.c (coff_symfile_read): tell condense_misc_bunches
1367 whether we're mainline.
1369 * symfile.h (sym_fns): Remove unused sym_discard member.
1370 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
1372 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
1373 the environment variable is not.
1374 * infcmd.c (finish_command): Use filtered printfs.
1375 * cplus-dem.c: Add struct tags to a few unnamed structs.
1376 * valops.c (value_coerce_array): Improve comments.
1377 * valprint.c (type_print_varspec_suffix): Print array size only
1378 if greater than zero.
1379 * m88k-tdep.c: Shift some lines left by one space, that had
1380 apparently been trashed at some point.
1381 * TODO: More things to do, a few got done.
1383 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1385 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
1386 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
1388 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
1389 * expread.y, findvar.c, symmisc.c: Ditto.
1390 * printcmd.c (address_info): Update printed forms of LOC_
1391 symbols. Elim LOC_EXTERNAL.
1392 (print_frame_args): Keep track of param stack offsets before
1393 re-looking up to find the local register param is kept in.
1395 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
1396 Further integration of mipsread into gdb. Eliminate unused
1397 routines, duplicate declarations. Handle static symbols in
1398 psymtabs as well as external symbols. When reading symtabs,
1399 insert symbols into the correct block (global, static, or a local
1401 (read_mips_symtab, parse_partial_symbols): Don't pass useless
1403 (mipscoff_symfile_read): Don't call select_source_symtab.
1404 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
1405 rather than SYMBOL_VALUE.
1406 (parse_external): Comment clobbering of top_stack.
1407 (parse_partial_symbols): Update comments. Allocate and parse
1408 static symbols as well as external symbols. FIXME, enum values
1409 are not handled in this pass, but should be. Inline new_psymbol.
1410 Use SYMBOL_VALUE_ADDRESS.
1411 (psymtab_to_symtab_1): Read symbols into global static block
1412 by default (until enter some function's local block context).
1413 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
1414 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
1416 * source.c (select_source_symtab): Select a source symtab
1417 from either the symtabs or, failing that, the psymtabs.
1418 (list_command): Update error message.
1419 (forward_search_command, reverse_search_command): Use getc, not
1420 fgetc, for speed. FIXME, add comment about buffers that die if
1421 overrun by long line.
1423 * values.c (unpack_field_as_long, modify_field): Avoid shifting
1424 by an entire word, which is not portable, if we have a 32-bit
1425 field. (Code in dbxread.c already turns such bitfields, if
1426 aligned, into ordinary ints, but fixing this will help for other
1427 symbol formats and for future changes.)
1428 * core.c (core_open): Handle ANSI const brain death.
1429 * utils.c (vprintf): Fix varargs typo.
1431 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1433 * findvar.c (find_var_value): Handle &function better.
1434 * TODO: Document work needed on &fn and &array.
1435 * printcmd.c (print_address_symbolic): New arg is the prefix
1436 to print if a name is printed.
1437 (print_address_demangle): Honor "set print address" now.
1438 Use new arg above to improve spacing of output.
1439 * valprint.c (val_print): When printing function pointers,
1440 print symbolic form too.
1441 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
1443 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1445 * core.c (memory_error): Reword error msg to mislead less.
1447 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
1449 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
1450 parse_partial_symbols): Use newer BFD internals (external_filehdr
1451 and external_aouthdr), byte-swap the fields that we care about
1452 before using them, and make the file header data local to
1453 read_the_mips_symtab rather than global.
1455 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
1457 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
1458 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
1460 * main.c (command_line_input): Flush stdout and stderr
1461 before every call to readline. This reportedly fixes a bug
1462 that comes up in Sys V running emacs-gdb and/or xxgdb,
1463 when stdin/out are pipes or sockets.
1465 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1467 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
1468 Avoid declaring Makefile dependencies, because GNU Make stupidly
1469 tries to update it if we do.
1471 * coffread.c: Revise for minor changes to bfd internal coff
1474 * configure: If -template= is given a relative path, make it
1475 absolute before recurring in subdirectories.
1477 * configure, configure.in, Makefile.in: Install "configure" script
1478 as replacement for config.gdb.
1479 * config.gdb, Makefile.dist, Makefile.sdir: Remove
1480 * README: Update for configure, mostly. FIXME.
1482 * Add dec3100 as equivalent to littlemips. Indicate in all host &
1483 target config files that they are for the host. When the lines
1484 get copied into the Makefile, this makes it more obvious what's
1487 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1489 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
1490 tabs, which end up in the disassembler output inadvertently.
1492 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1494 Make it compile cleanly in an ANSI GCC2 environment.
1496 * blockframe.c: <stdio.h>
1497 * cplus-dem.c: free takes a void *, ifdef __STDC__
1498 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
1500 * defs.h (alloca): Avoid doing anything if alloca already def'd.
1501 * stddef.h, stdlib.h: Remove these files.
1502 * symtab.c: Avoid declaring qsort, close.
1503 * symfile.c: Avoid declaring close.
1504 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
1505 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
1507 Assorted other changes.
1508 * dbxread.c: include "libaout.h", not "liba.out.h".
1509 * printcmd.c (print_frame_args): Set recurse properly for
1510 indentation of struct and array parameters.
1511 * valops.c (value_cast): Allow cast to void.
1512 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
1513 single_step() in a target-independent fashion.
1514 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
1515 set up to be ready to continue. This makes us target independent.
1516 * infptrace.c (child_resume): Remove call to single_step; now
1517 can single step a SPARC target of any kind.
1519 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1521 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
1522 docn into separate sections---basically chapters, plus two loose
1523 pieces that can be configured to go in different places. This
1524 allows GNU m4 to preprocess the manual without coredumping.
1526 * Makefile.dist: tell TeX where to find texinfo.
1528 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1530 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
1531 the new target "rdl-apps.texinfo" which captures the Makefile
1532 variable that records where to find the Readline libraries.
1534 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
1536 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
1537 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
1538 * defs.h (const, volatile): Only define if not already defined.
1539 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
1541 * README: Update for release 3.95.
1542 * config.gdb: Don't create readline dir in subdir builds.
1543 * main.c: Include with "..." form for non-system include files,
1544 so "gcc -MM" for "make depend" works.
1545 Include readline files with "...h" rather than <readline/...h>.
1546 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
1548 * coffread.c: Undo minor damage done by Rich Pixley. Use
1549 different internal and external representations of COFF
1550 data structures. Use new BFD routines for swapping them in and
1552 * symfile.c (free_named_symtabs): Avoid freeing file names that
1553 are null or empty. Old i960 tools seem to produce files that
1554 claim to have empty names, causing each successive file read
1555 to blow away the previous one.
1556 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
1557 Move deferred_stores to top of file, but don't separate its
1558 #define's from its variable. Add commentary.
1559 * Makefile.dist: Fix Rich damage; undo "configure" changes in
1560 favor of keeping the (working) config.gdb. Move readline
1563 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
1565 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
1567 * infptrace.c (fetch_registers): no result, since now void.
1568 * tconfig/news: target depends on m68k-tdep too.
1570 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1572 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
1575 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
1576 applied various small fixes due to or inspired by RMS comments
1578 * doc/gdb.texinfo: finished using all RMS comments, save those for
1579 appendices on readline and cmd history (which are in other source
1582 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1584 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
1585 chapter 9; (2) documented 'break' command's menu mode for
1586 overloaded names, in response to hgs problem report C++ p-31
1588 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1590 * doc/gdb.texinfo: (1) better introductory example; (2) more
1591 consistent use of @code, @samp, @file, @kbd throughout; small
1592 cleanups to first three nodes; (3) new "Contributors" node;
1593 (4) Appendix, Renamed Commands; (5) divert specialized startup
1594 instructions to "Targets" chapter for generic manuals, while
1595 leaving them up front for manuals specific to specialized
1596 environments; (6) apply fixes from RMS comments through chapter 4.
1598 * pretex.m4: modify explanatory text slightly (and redefine
1599 "regexp") to keep GNU m4 from complaining. (It still crashes
1600 later, but one step at a time...)
1602 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
1604 * readline/readline.c (update_line): Avoid dereferencing a pointer
1605 before comparing it to its bounds. Saber caught this.
1606 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
1607 and only set PC if tgetstr returned non-null. Saber caught this.
1609 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1611 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
1612 stuff for config manual) here where it counts; updated
1613 to use new subdir structure (gdb/doc/).
1615 * Makefile: generated from above via
1619 * gdbint.texinfo: added instructions on generating gdb.info* files
1620 locally for release. These are ordinary info
1621 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
1622 Makefile)---but due to use of texinfo 2, can't count on makeinfo
1623 to generate these, so we distribute them already formatted.
1625 * gdb.texinfo: included full Info node and menu crud (as generated
1626 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
1628 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
1629 put in comments-for-future gdb.info target (one day makeinfo will
1632 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1634 * gdb.texinfo: Updated to include new or old undocumented
1635 commands, at least the following (perhaps some others I forgot to
1636 record): info f, info float, info path, info program, info s, info
1637 set, info source, info terminal, info types, info user, set/show
1639 Also covered all recent GDB command renames for v4.
1641 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1643 * mipsread.c: Rather than keeping count of how many symtabs
1644 and psymtabs we have, for sorting purposes, count them when
1645 we need to sort. This fixes bug in rereading of symbol tables.
1647 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1649 * infcmd.c: renamed "info path" to "show paths"

1664 symtab.h, target.c, target.h: Lint.
1665 * core.c: setup and select frame after reading shared libs,
1666 else reading shared libs will clobber them. Lint.
1667 * utils.c (error): Force out any buffered wrap text.
1669 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1671 * remote.c: Remove decls of memory_insert_breakpoint
1672 and memory_remove_breakpoint, no longer used. (Suggestion of
1675 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
1676 to make it easier to interface to "configure"'d libraries.
1678 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
1680 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
1681 aliases for set/show print.

2192 (add_target): Call add_cmd and mess with targetlist->doc.
2193 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
2194 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.

2224 command is add-symbols.
2225 * target.c (dummy_target): Permit add_syms_addr_command.
2227 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2229 Permit symbols to be superseded when new symbol files have
2230 been read in, particularly for VxWorks.
2232 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
2233 to the main file, as well as to include files. Also, put global
2234 functions into the global psymtab, to make "i fun" work.
2235 (end_psymtab): Free named symtabs and psymtabs for a file, once a
2236 new psymtab for it has been read.
2237 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
2238 a file, once a new symtab has been read for it.
2239 * mipsread.c: FIXME. We need to do the same for MIPS, but it
2240 looks harder to determine the top-level block before it's been
2241 queued to the psymtab list.
2243 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
2244 If we have wiped out any old symbol tables, clean up at end of
2246 (symbol_file_command): Don't reference symfile_fns if it's zero.
2248 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
2249 defines for the blocks of a blockvector that contain global and
2250 file-static symbols and the first of the smaller scope contours.
2251 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
2252 decode_line_1, make_symbol_completion_list): Use the above.
2253 * coffread.c (end_symtab, patch_opaque_types): Ditto.
2254 * dbxread.c (end_symtab): Ditto.
2255 * expread.y (block): Ditto.
2256 * mipsread.c (throughout): Ditto.
2257 * symmisc.c (free_named_symtabs): Ditto.
2259 * symtab.c (list_symbols): Process the first symbol of the
2260 static psymbols list.
2261 (types_info): Restore this function from its untimely #if 0.
2262 It's not perfect, but it is better than nothing.
2263 (_initialize_symtab): Restore "info types".
2265 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2267 * m68k-stub.c: Remote stub for 680x0's, created from
2268 rem-m68k.shar (which is removed).
2269 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
2270 Remove RCS log stuff now that we use CVS and it blows our diffs.
2272 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2274 * symmisc.c (free_named_symtab): Make it work, in its current
2275 kludgy fashion. Change result to indicate if we blew away bkpts.
2276 * dbxread.c (end_symtab): Accumulate result from
2277 free_named_symtab and print warning if we blew user's state.
2278 * symfile.h: free_named_symtab now returns an int.
2280 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
2282 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
2283 is the first symbol read, even if not mainline.
2284 (dbx_psymtab_to_symtab): symfile might be zero, cope.
2285 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
2286 (set_section_command): New command ("section xxx yyy" -- should
2287 be renamed to "set section xxx yyy" FIXME) which sets the
2288 base address of a section of the exec file, overriding the
2289 virtual address that BFD reports.
2291 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2293 * exec.c: Add add_syms_addr_command to exec_ops, so you can
2294 load symbols at any address while examining an exec file.
2296 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2298 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
2299 for printing the float info is host-dependent, not
2300 target-dependent. FIXME.
2301 * i386-pinsn.c: Move #includes to top, remove useless ones.
2302 * i386-tdep.c: Don't bother including <.../reg.h> since we
2303 don't use it (and it doesn't exist on host systems).
2305 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
2306 Convert negative numbers properly.
2307 (ieee_test): Make numbers really random; fix format arg.
2309 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
2310 * core.c (core_detach): Unpush core_ops, which might not be on
2311 top. We used to just pop the top, which broke things. Don't
2312 need dont_repeat() any more.
2313 (core_file_command): Psst! Don't repeat it.
2314 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
2315 * expprint.c (print_subexp): Avoid switch fallthru on
2316 BINOP_ASSIGN_MODIFY, so we can print += and such.
2317 * frame.h: Fix typo.
2318 * inflow.c (kill_command): After killing inferior, print our
2319 current frame in the core file, if we have one.
2320 (generic_mourn_inferior): When inferior dies, either select
2321 the current frame (in the new target, e.g. core file), or
2322 set both the current and selected frames to NULL.
2324 Changes from Peter Schauer.
2326 * infptrace.c: Avoid <sys/ptrace.h> on USG.
2328 * Make all file names fit in 14 characters (sigh and damn!):
2329 mv hp300hpux-xdep.c hp300ux-xdep.c
2330 mv symmetry-xdep.c symm-xdep.c
2331 mv symmetry-tdep.c symm-tdep.c
2332 mv convex-opcode.h convx-opcode.h
2333 mv tm-vxworks960.h tm-vx960.h
2334 mv tm-vxworks68.h tm-vx68.h
2335 mv Makefile.srcdir Makefile.sdir
2336 mv gdb-int.texinfo gdbint.texinfo
2337 mv remote-sa.m68k.shar rem-m68k.shar
2338 mv remote-multi.shar rem-multi.shar
2339 * Makefile.dist, README, config.gdb, convex-pinsn.c,
2340 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
2341 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
2344 * command.c (user_info_1, user_info): New command for listing
2345 the user-defined commands.
2347 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2349 * dbxread.c (really_free_pendings): Clear file_symbols
2350 and global_symbols after freeing them; otherwise, running
2351 this function twice (if it appears twice on the cleanup
2352 chain), we try to free things twice.
2354 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
2355 based on text_addr (the address of text in core), not on addr (the
2356 offset between text in the .o file and in core). This change
2357 is from Peter Schauer.
2359 * main.c: Define ALL_CLEANUPS as a cast of zero.
2360 (return_to_top_level): Use it.
2361 (main): Do all cleanups after each command run as part
2362 of the gdb startup sequence. Also do all cleanups before
2363 entering the command loop, and every time we exit the command
2364 loop and reenter. Before, the cleanups from the startup sequence
2365 were being left undone until the first error!
2366 (command_loop): Rename do_nothing cleanup to command_loop_marker
2367 so we can see it easily when examining the cleanup chain.
2368 (init_signals): Add another do_nothing for signal handling.
2369 (quit_command): Only try to kill target if it has execution.
2370 Problems in the target stack got us into a state where
2371 inferior_pid was nonzero but none of the targets had execution.
2372 In this state you couldn't exit gdb.
2374 * dbxread.c: Two changes from Peter Schauer.
2375 (echo_command): Fflush output after an echo command.
2376 (show_history): Pass all args to cmd_show_list.
2378 * utils.c (init_malloc): Call mtrace to turn on tracing
2379 if the environment variable MALLOC_TRACE is set to a file name.
2380 * mtrace.c: Add source file which provides a log of every malloc,
2381 free, and realloc to a trace file.
2382 * mtrace.awk: Add source file which analyzes the trace file.
2383 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
2384 (VERSION): Roll to 3.94.3.
2386 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
2387 (check_duplicates): Don't bother with watchpoints.
2388 (set_raw_breakpoint): Comment about danger of this routine.
2389 (watch_command): Parse and eval all args before calling
2392 * solib.c (find_solib): Avoid error in referencing memory to
2393 see if any more shared libraries have been added. This is
2394 particularly useful if the target has terminated. Bug reported
2397 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
2398 in bringing up 3.94.2 on the Sun-3.
2400 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
2401 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
2402 expression (in scope) before reenabling watchpoint.
2403 * signame.c (init_sigs): Add missing declaration of i, fix
2404 sys_siglist declaration.
2405 * source.c (list_command): Fixed range computation to use
2407 * stack.c (backtrace_command): Do not allow command if target has
2408 no stack, print informative error message.
2409 * target.c (target_command): Do not write into command line
2410 because this fails if the target command is used in a user defined
2411 command. [This change was enhanced by gnu to support any-
2412 unique-prefix matching on target names.]
2413 * valops.c (value_struct_elt): Avoid infinite loop on an
2414 erroneous attempt to print the member of function (try p main.p).
2416 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2418 * expread.y (name_no_typename): Avoid reduce/reduce errors
2419 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
2420 Since the GDB parser really doesn't use name_no_typename in a
2421 name-only context, the parser can't tell the diff between
2422 names and numbers here. Avoid allowing a name_no_typename
2423 to be a NAME_OR_*INT to resolve the conflict.
2425 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2427 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
2429 * valprint.c (val_print_fields): bitfield printing didn't handle
2430 byte order. Indirect through a few more fns to cope.
2432 * values.c (modify_field): also cope with byte order.
2434 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2436 Cleanup for release 3.94.2:
2438 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
2439 include files. Roll version to 3.94.2.
2441 * coffread.c (init_stringtab): Read length into unsigned char
2442 array before swapping; don't assume 32-bit longs.
2444 * target.c (target_info): Don't bother with get_sym_file, just use
2445 the symfile global variable.
2446 * symtab.h, symfile.c (get_sym_file): Delete it.
2448 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
2449 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
2450 (read_type): Replace one more error() with complain().
2452 * mipsread.c (parse_partial_symbols): Replace printf with complain.
2454 * i960-tdep.c: Fix copyright attribution.
2456 * config.gdb: Quote all backquotes in doublequotes. You can
2457 quote me on that. BSD 4.4 shell found this one.
2459 * infptrace.c (throughout): The third argument to ptrace is an
2462 * infrun.c (wait_for_inferior): When program has terminated, we
2463 have to call target_terminal_ours before we pop that target off
2464 the stack (e.g. before a call to target_kill or
2465 target_mourn_inferior). This fixes problem where a program
2466 terminates, then GDB stops for (tty output) and you have to type
2467 "fg" to the shell to resume it. FIXME: This code for what to
2468 do after termination really should be in normal_stop instead.
2470 * gdbcore.h (read_memory_check): Change declaration; it changed
2473 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
2474 4.4 prereleases, this avoids a bug in their sgtty compatability
2476 * remote.c: Use terminal.h rather than hand-rolling the same.
2478 * signame.c, signame.h (psignal): Arg is unsigned, not int.
2479 * utils.c (strsave, strstr): Fix arg types.
2480 * valprint.c (val_print): lint
2482 MIPS symbol table support from Per Bothner:
2484 * symfile.c (symtab_fns): Remove initializer table that needs to
2485 be hacked for each new symbol file format supported.
2486 (add_symtab_fns): New function, chains symbol table
2487 handlers into the global list.
2488 (symfile_init): Search this list.
2489 * symfile.h: Add next pointer, declare add_symtab_fns.
2490 * coffread.c (_initialize_coffread): Call add_symtab_fns.
2491 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
2493 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
2494 symbol *). Thus, we no longer need the hack to trash
2495 pst->filename. Good, since that hack confused code in symfile.c!
2497 (reorder_symtabs, destroy_all_symtabs): Removed static
2498 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
2499 Instead, the latter now uses a temporary array (stack-allocated
2500 from an obstack, and then freed).
2502 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
2503 haven't been set in the outermost stBlock of a procedure. This was
2504 a problem with f77 binaries on Ultrix 4.?.
2506 (new_symtab, new_symbol, new_type): Continue changing code to use
2507 obstacks more and otherwise conform to dbxread internal style.
2508 Made the free_code of symtabs be free_linetable (as in dbxread)
2509 instead of free_contents. This implies memory leaks when reading
2510 a new symbol table, until the conversion is finished. Did change
2511 (struct symbol) and (struct type) to be allocated on the
2512 symbol_obstack. Blocks and blockvectors are among the things
2515 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
2516 tested much, but it solved one problem (reported by Meissner), and
2517 cleans up some other things. The problem happened when an
2518 included file contains actual code (functions) and not just
2519 definitions. The mips coff is a little inconvenient there, since
2520 it may cause a procedure to be mapped to the wrong psymtab.
2522 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
2523 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
2524 this will need work for the new core paradigm.
2526 Opcode patches from the net:
2528 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
2529 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
2530 missing altogether - they are added here. From Bruce Bauman.
2531 * mips-opcode.h: The low mask for C0 instructions was too small.
2532 From Garrett Lau. I modified the fix to check the entire 32-bit
2535 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
2538 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2540 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
2542 * dbxread.c (read_type): Pointer subtraction (value_sub in
2543 valarith.c) sometimes failed because the types of the
2544 pointers being subtracted were not identical.
2545 These differed because dbxread.c was allocating pointer types
2546 using dbx_alloc_type+smash_to_pointer_type instead of
2547 lookup_pointer_type. I failed to find a justification for the
2548 former, so I changed it to use the latter. Similarly, I
2549 replaced smash_to_function_type by lookup_function_type,
2550 and smash_to_reference_type by lookup_reference_type.
2552 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
2553 _initialize_mipsread): corresponding changes.
2555 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
2557 * source.c (mod_path): Do tilde_expand on each component of the path,
2558 rather than on the (list of) paths as a whole.
2559 (print_source_lines): Set first_line_listed in addition to
2560 current_source_symtab and current_source_line. If the source was
2561 not findable, after a "dir" command to fix the problem,
2562 a "list" would get the wrong lines.
2564 While I was there... (gnu):
2566 * dbxread.c (read_type): Change error to complaint.
2568 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2570 First attempt at detailed understanding of symbol table memory alloc.
2572 * dbxread.c (dbx_symfile_read): Free our string table if we
2573 aren't the mainline. Free the "info" struct since we're done with
2575 (init_psymbol_list): Free any previously allocated psymbol lists.
2576 (): FIXME: Should realloc-down the psymbol lists when done reading
2577 the main symbol file?
2579 * symmisc.c (free_symtab): Free fullname field too.
2581 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
2582 (REGISTER_ADDR): Make result type unsigned int.
2584 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
2585 define REGEX must also define REGEX1 (its dependency).
2587 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2589 * tconfig/i960: No longer works, points you at vxworks960 or
2592 * xgdb.c, XGDB-README: Remove file. Users can get the much
2594 * Makefile.dist: Remove all trace of xgdb.
2596 * breakpoint.c (breakpoint_1): Pass demangle arg to
2597 print_address_symbolic.
2598 (clear_breakpoints): Remove unused function.
2599 (breakpoint_re_set_one): Guts of breakpoint_re_set.
2600 (breakpoint_re_set): Use catch_errors to do them all anyway.
2602 * gdb-int.texinfo (Host versus Target): Add section on what is
2603 a "host" feature versus what is a "target" feature.
2605 * infcmd.c (path_command, path_info): Handle the PATH variable
2606 (object search path) as conveniently as the source search path.
2607 * environ.c (set_in_environ): Set some vars in GDB's environment,
2608 in addition to the child's. PATH, G960BASE, G960BIN for starters.
2609 * source.c (mod_path): New function, from guts of
2610 directory_command, modifies a path. Used by path_command.
2611 (directory_command): Call it.
2612 * defs.h (strsave): Declare.
2614 * utils.c (sevenbit_strings): Add new printing option.
2615 (printchar): Use it.
2616 (strsave): Provide this handy helper routine.
2617 (set_width_command): Rename set_screen_width_command.
2618 (_initialize_utils): "set screen-width" => "set width";
2619 "set screen-height" => "set height"; add sevenbit-strings.
2621 * infcmd.c (do_registers_info): Print floating point registers
2622 in raw hex as well as float format, regardless of whether it is
2623 a "virtual" convertible register.
2624 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
2625 regs as a double, just in case it's being used that way.
2626 * values.c (unpack_long): Comment on array/function coercion.
2627 (unpack_double): Argument is in target byte order now. For
2628 integer arguments, just call unpack_long and float the result.
2629 * m68k-tdep.c: include defs.h for "const" handling.
2630 * remote-nindy.c: Use ieee-float stuff.
2631 (nindy_fetch_registers): Unpack double regs to host double, then
2633 (nindy_store_registers): Pack extendeds to host double, flip
2634 around by misusing unpack_double, send as target double.
2636 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
2637 zero, as when stopped at the first instruction of a process.
2639 * blockframe.c: Fix filename in comment (param.h => tm.h).
2640 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
2641 * tm-68k.h: Fix typos.
2643 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
2645 Changes from a bringup on the DEC Vax under Ultrix 4.0.
2647 * coredep.c (fetch_core_registers): Pass end-address of register
2648 section to register_addr as expected. Don't call supply_register
2649 if we'd just pass it garbage.
2651 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
2653 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
2655 * target.c (push_target, target_info): Cast enums to int for < or
2658 * stack.c (print_frame_info): Identify source file & line
2659 even if we can't print it.
2661 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
2663 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
2665 Clean up IEEE floating point support.
2667 * ieee-float.h: New file.
2668 * ieee-float.c: Write real routines to convert between host
2669 doubles and various target IEEE extendeds.
2670 * m68k-xdep.c: Eliminate assembler code for extended floats.
2671 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
2672 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
2673 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
2674 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
2675 double_to_ieee_extended.
2676 * i960-tdep.c: Define ext_format_i960.
2677 * m68k-tdep.c: Define ext_format_68881.
2678 * sparc-tdep.c: Define ext_format_sparc, though unused.
2679 * Makefile.dist (HFILES): Add ieee-float.h.
2680 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
2683 Obsolete the "coffstrip" program in favor of using BFD's strip.
2685 * nindy-share/coffstrip.c: Remove file.
2686 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
2687 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
2688 * tconfig/nindy960: Remove reference to coffstrip.o.
2690 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
2692 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2694 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
2695 * dbxread.c: Remove static symfile_bfd.
2696 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
2698 * inftarg.c (child_detach): Pop the child_ops vector if the
2699 detach is successful.
2700 * remote-nindy.c (nindy_create_inferior): Don't push a new
2701 nindy_ops since nindy uses the same one for execution and memory
2703 * core.c (core_ops): Use child_attach and child_create_inferior
2704 rather than default attach and create_inferior functions.
2706 Handle floating point registers in core files.
2708 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
2709 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
2710 This version untested since BFD doesn't yet support sun3 core
2712 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
2713 conventions. Fix comments and style. This version has not
2714 been compiled yet, since we have no HP inhouse.
2715 * core.c (get_core_registers): Look for two sections, ".reg"
2716 and ".reg2", and pass both to fetch_core_registers sequentially.
2718 Revise directory path yet again.
2720 * source.c (forget_cached_source_info): Not static any more.
2721 (init_source_path): New default source path is "$cdir:$cwd".
2722 (dir_command): Handle variable arguments ($cdir, $cwd).
2723 (source_info): Print "Compilation directory" rather than
2724 "Originally compiled in" to remind people of $cdir.
2725 (openp): If the path contains $cwd, use current directory.
2726 (open_source_file): If compilation directory is known, replace
2727 first $cdir in path with the compilation directory.
2728 (print_source_lines): Even if we can't print the lines, set the
2729 current symtab and line for future commands like "info source" or
2730 "breakpoint". Also, error message now contains the file name,
2731 line number, and file access error message.
2732 (_initialize_source): Fix help text to describe changes.
2733 * main.c (cd_command): Forget cached source info when we chdir.
2734 * utils.c (strstr): Add simple implementation.
2736 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
2738 * coffread.c (read_one_sym, init_linetable, init_stringtab):
2739 Byte-swap COFF symbol tables if necessary when reading them in.
2740 Use complain() to replace error message in one spot. Needs
2741 corresponding change in bfd/coff-code.h to make some symbol
2742 swapping routines non-static.
2744 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
2746 Merge changes from Eirik Fuller, for UTek.
2748 * defs.h (errno): Add declaration.
2749 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
2750 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
2751 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
2752 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
2753 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
2754 declarations of errno.
2756 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
2758 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
2759 <rpc/rpc.h> and <rpc/types.h>.
2761 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
2763 * i960-tdep.c (examine_prologue): Add new argument limit,
2764 which stops the scan at the end of the prologue, or at the PC.
2765 This fixes a problem where it walks down into the code for the
2766 user's statements if that code looks like function prologues.
2767 Mark Fox and I have been bouncing this code back and forth, making
2768 small changes to it. Callers changed to match.
2770 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
2772 Cleanup for gdb-3.94 release final:
2774 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
2775 the .c files from vx-share and nindy-share, from the various
2776 macros, since they are not found via ALLDEPFILES.
2777 (SFILES): Add tm-i960.h.
2778 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
2779 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
2781 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
2782 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
2784 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
2786 * am29k-tdep.c: Add contribution line.
2787 (examine_prologue): Cache information about function prologues in
2788 the misc-function-vector to avoid lots of references over the
2789 serial line while examining instructions.
2791 * core.c (core_close): New function made from cleanup_core.
2793 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2794 remote-vx.c, remote.c, target.c, target.h,
2795 Update target_ops vector to add attach, close, and load entries.
2796 Use add_syms_addr_command, not add_file_addr_command, for
2797 add_file. Break out close routine from existing code.
2799 * dbxread.c (really_free_pendings): Don't free pending_blocks;
2800 they are in an obstack.
2801 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
2803 (define_symbol): Add symbol type parameter; change callers;
2804 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
2805 it to influence the symbol class on the i960.
2806 (define_symbol): Swap LOC_CONST's into target byte order.
2808 * exec.c (exec_close): New function.
2809 (exec_file_command): Call it.
2811 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
2812 Fix byte order of frame pointer.
2813 (read_var_value): Result of 0 if var's value can't be found,
2814 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
2815 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
2816 (locate_var_value): Use read_var_value and use its lazy address
2817 as the location of the var's value. Lint.
2819 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
2822 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
2823 obsolete Intel versions in favor of vxgdb versions.
2824 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
2825 code dealing with byte order of values, which Intel did in host byte
2826 order rather than gdb-4's target byte order.
2827 (i960_frame_chain_valid): Move to nindy-tdep.c.
2828 (examine_prologue, skip_prologue, frame_find_saved_regs,
2829 frame_args_address, leafproc_return, saved_pc_after_call,
2830 pop_frame): Add vxgdb versions from Mark Fox.
2831 (examine_prologue, frame_struct_result_address): Add code
2832 to deal with the saved value of G13 (struct return address
2834 (frame_args_address): Modify Mark's version to prefer the
2835 saved value over the current value in the topmost frame.
2836 Cache result in the frame info to avoid performance hair in
2838 (print_fault): Add gdb960 code for printing faults.
2839 (_initialize_i960): Actually call check_host.
2841 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
2842 add stub routines. FIXME, these currently just return zero!
2844 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
2845 (attach_command): Call target_attach, not target_open, now.
2847 * infrun.c (normal_stop): Make global, not static, for vx_attach.
2848 (child_attach): Rename from child_open.
2849 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
2850 don't confuse it with a zero step_resume_break_address.
2852 * inftarg.c (child_detach): Eliminate inferior_pid test.
2853 (child_files_info): Clean up message a bit.
2854 (child_ops): Use child_attach, not child_open, to attach.
2856 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
2857 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
2858 findvar.c to here, since it depends on the contents of the
2859 shadow_contents of breakpoints, but keep if #if 0 since it is
2862 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
2865 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
2866 (ptype_command, display_command): Eliminate have_inferior_p and
2867 have_core_file_p in favor of target_has_stack or
2868 target_has_execution.
2869 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
2870 code for actually finding the values of arguments, though we still
2871 keep track of the maximum stack offset for use in printing unnamed
2872 arguments. Handle missing FRAME_ARGS_ADDRESS.
2874 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
2875 (struct nindy_regs): Define registers passed to/from nindy.
2876 (nindy_fetch_registers, nindy_store-registers): Translate between
2877 nindy and GDB formats for the registers.
2878 (dcache_init): Statically allocate the cache, since it was being
2879 allocated by a malloc that was never freed anyway.
2880 (nindy_create_inferior): Error, not core dump, if no exec file.
2881 (nindy_before_main_loop): Use target_load, not target_add_file.
2883 * remote-vx.c (net_load): Specify large timeout for load
2884 requests. Allow user to break out with INTERRUPT.
2885 (net_break): Remove useless code, clean up. Change callers.
2886 (parse-args, skip_white_space, find_white_space): Clean up arg
2887 parsing to cope with quoted strings.
2888 (net_wait, net_quit): Never call error, just return status.
2889 (vx_read_register, vx_write_register): Cleanup status checking.
2890 #ifdef the code based on which CPU we are using (960 or 68k),
2891 FIXME, this should be completely general but it isn't yet.
2892 (vx_xfer_memory, vx_resume): Cleanup status checking.
2893 (vx_run_files_info): Improve message.
2894 (vx_load_command): Renamed from vx_add_file_command. Allow load
2896 (net_ptrace): Remove unused routine.
2897 (vx_wait): Adopt code from vxgdb960 to cope with broken
2898 connections to target machine and prompt to disconnect. Remove
2899 debug printouts. Map some EVENT_'s to SIGnals.
2900 (add_symbol_stub, vx_open): Print names of object files we found,
2901 and "ok" if we read their symbols OK. Clarify output in general.
2902 (vx_attach, vx_detach, vx_kill): Add these commands.
2903 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
2904 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
2905 "info files" output, and create_inferior, since we already have
2908 * stack.c (frame_info): Replace Frame_unknown with 0.
2909 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
2910 (return_command): Pop until the PC matches as well as the FP,
2911 so it works even if the FP is shared with another function,
2912 as in "frameless" or "leaf" procedures.
2914 * symfile.c (load_command): renamed from add_file_target_command.
2915 (add_syms_addr_command): renamed from add_file_addr_command.
2916 (add_syms_command): Stub to call target_add_syms.
2917 (_initialize_symfile): Change command names and descriptions,
2918 add-file => add-syms, and load from alias to its own command.
2920 * target.c (kill_or_be_killed, maybe_kill_then_attach,
2921 maybe_kill_then_create_inferior): Default for attempts to start
2922 a process, if one is already running, is to ask about killing
2923 it and retry if yes.
2924 (upstack_create_inferior): #if-0 it, strata obsolete it.
2925 (push_target, unpush_target, pop_target): to_close() a target
2926 before unstacking it.
2927 (target_info): Renamed from target_files_info.
2928 (_initialize_targets): Rename "i files" as "i target", accessible
2931 * target.h: Improve comments about the target_ vectored routines.
2933 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
2934 Convert commenting style to standard GNU style.
2935 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
2936 (SKIP_PROLOGUE): No longer a no-op.
2937 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
2938 (*_REGNUM): Sort register numbers.
2939 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
2940 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
2941 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
2942 are now 10 byte extendeds, not 8 byte doubles.
2943 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
2944 for nindy versus vxworks targets. FIXME, this should possibly go
2945 in the target vector.
2946 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
2947 frame_saved_regs and arg pointer with each frame.
2948 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
2949 (FRAME_ARGS_ADDRESS): Use cached result.
2950 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
2951 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
2952 (PRINT_RAMDON_SIGNAL): Call print_fault.
2953 (POP_FRAME): Now works.
2955 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
2956 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
2957 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
2958 (ADDITIONAL_OPTION_HANDLER): use target_load, not
2961 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
2962 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
2964 * valarith.c (value_subscripted_rvalue): Avoid handling
2965 floats and doubles specially; it gave alignment errors. Lint.
2967 * valops.c (value_of_variable, value_of_this): Error if unknown
2970 * valprint.c (print_floating): Bcopy rather than pointer-deref,
2971 to avoid alignment problems.
2972 (value_print): Handle unknown value address.
2973 (cplus_val_print): Two args are ignored; remove them. Change caller.
2974 (val_print): Use unpack_long rather than pointer-deref.
2977 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
2978 to avoid alignment problems.
2979 (value_being_returned): Error if return value unknown.
2980 (set_return_value): Add bogosity warning, FIXME. *
2982 * TODO: A woman's work is never done.
2984 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
2985 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
2986 Add ieee-float.o to OBS.
2987 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
2988 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
2989 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
2991 Changes to generalize the VxWorks RPC protocol slightly, to handle
2992 i960 as well as 68000.
2994 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
2995 * vx-share/reg.h: Produce i960 regs #ifdef I80960
2996 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
2997 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
2998 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
2999 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3000 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3001 so they will move in target byte order rather than network
3002 byte order (happens to be the same).
3004 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3006 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3008 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3011 Add contribution lines to various files, showing where they
3014 * breakpoint.c (break_insn, check_break_insn_size,
3015 read_memory_nobpt): Remove to mem-break.c.
3017 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3020 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3021 entry has bad register number. This change is not
3022 tested in this release, FIXME.
3024 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3027 * value.h: Force value's contents field to be aligned to hold
3028 at least a double or a long long (if supported). This avoids
3029 doing bcopy's in and out of the contents field.
3031 (step_1): Avoid coredump under obscure circumstances when we
3034 * symtab.h (misc_info): Add field to misc function vector for
3035 any kind of cached information the target code desires. AMD
3036 29000 uses this to avoid repeating examine_function_prologue's.
3038 * coffread.c: Lint. Remove static symfile, read_section_header.
3039 core.c (have_core_file_p): Lint: remove.
3040 expprint.c (print_subexp): Lint.
3041 infptrace.c, valops.c, valprint.c: lint.
3043 Roll in changes from vxgdb-5.0.1:
3045 * symtab.h: Comment byte order of each address class. Add
3046 LOC_LOCAL_ARG for frame-relative args (960).
3047 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3048 symtab.c, symmisc.c: ditto.
3050 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3052 * remote.c (remote_resume): Error if resume with a signal.
3054 * symfile.c (prim_record_misc_function): Clear misc_info.
3055 (fill_in_vptr_fieldno): Check stub type of arg.
3057 * valops.c (value_cast): Avoid looking up names of types whose
3058 name we don't know, to prevent coredump. Sun CC produces typedef
3059 rtx and the name of *rtx is zero...
3061 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3063 Roll in changes from final AMD 29000 port (Tiemann).
3065 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3066 for ../include/a.out.encap.h. This might not work now that BFD
3067 is separately compiled. Instead, BFD support for encap will have
3068 to translate machine type 29k into the right COFF_MAGIC.
3070 * infcmd.c: Remove references to inferior_pid that aren't used
3071 in actual ptrace calls; use target_has_execution, etc.
3072 (have_inferior_p): Remove function.
3073 (program_info): Print target info rather than "process number";
3074 avoid gratuitous messages unless from_tty.
3075 (run_stack_dummy, finish_command): Set proceed_to_finish.
3076 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3077 main.c: Lint. Lose have_inferior_p().
3078 inferior.h (have_inferior_p): Remove, lint.
3079 (proceed_to_finish): Add flag to ask that all regs be saved
3080 by normal_stop, for the few commands that need it, speeding up
3081 serial I/O. Add comments to stop_registers.
3083 * remote-eb.c: Remove newline from breakpoint message we grep
3084 for. Never time out when running the user program.
3088 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3090 Roll in changes from vxgdb-5.0.1:
3092 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3093 symbol in its raw form, we are processing an unlinked ".o" file.
3094 See if the target environment has assigned it an address, using
3095 target_lookup_symbol (VxWorks does), and enter it into the symtab
3098 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3099 68k versions for a simpler version that assumes zero FP at bottom.
3100 Fixes bug of truncated stack reports.
3102 * target.h (target_lookup_symbol): Define this routine's args
3103 and result, finally.
3105 * target.c (nosymbol): Default routine for target_lookup_symbol.
3106 (target_default): Default lookup_symbol and call_function too.
3107 (files_info): Only print has_all_memory warning if a non-dummy
3110 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3111 vx_convert_from_virtual): If target does not have floating point,
3112 zero register "values", and avoid doing cross-net conversions.
3113 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3114 (vx_open): Rearrange code that attaches to target and reads
3115 symbols for all loaded modules, to work if some of the modules
3116 are not accessible. Add symbol_stub() and add_symbol_stub()
3117 as callbacks from catch_errors(). Allow connect attempt to be
3118 interrupted painlessly with ^C (FIXME, there are still some bugs
3119 if the interrupt happens during symbol reading.). Print
3120 final message with puts_filtered, since symbol messages are
3125 * main.c (catch_errors): Only print errstring if non-null.
3126 (command_loop): Avoid an ioctl per command to test ISATTY.
3128 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3129 (vx_xfer_memory): Return correct result!
3130 (vx_files_info): Indicate whether target has float or not.
3131 (vx_lookup_symbol): Complain, not error, if target gone.
3132 (vx_open): Print "Connected" msg before disabling immediate-quit.
3133 [FIXME: lookup_symbol and vx_open changes need testing.]
3135 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3136 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3137 contributor lines and update copyrights to 1991.
3139 Changes from an attempted H-PUX host port:
3141 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3142 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3143 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3144 * remote-vx.c: include <sys/time.h> for HPUX.
3145 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3146 "core_file_command" routine to BFD regime. May not work yet.
3148 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3150 * xgdb.c: Replace X10 version with some VJ version.
3151 (FIXME: Its copyright assignment is not on record.)
3152 * xgdb.c: Update include files to X11R4 (Xaw crud).
3153 (xgdb_display_source, create_text_widget): fix call to
3154 get_filename_and_charpos. Rewack source window stuff for X11R4
3155 (gleaned from include files, and "nm's" of binary libraries, since
3156 I had no doc available).
3157 (append_selection, append_selection_word): Disable with FIXME
3158 since R4 changed interface here.
3159 (create_buttons): Add back the old set of buttons.
3160 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3162 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3163 Roll VERSION to 3.94 (not yet final though).
3165 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3167 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3168 obstack_int_grow, obstack_int_grow_fast): Eliminate
3169 cast on left of assignment, which gives MIPS cc fits and is
3172 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3173 F_ALIAS. Use printf, not fprintf, when not passing a file
3175 (compare_opcodes): Check that identical instructions have
3176 identical opcodes, complain otherwise.
3178 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3179 was reported by Roland McGrath.
3180 (unimp): Only match if exactly zero instruction. (Roland)
3181 (branches and traps): Generate all variations of these
3182 instructions with macros, based on a single call that defines
3183 each condition name and its binary representation.
3184 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3186 * valprint.c (val_print_fields): Take, and use, format parameter.
3187 This means that "p/x struct" again prints the elements in the
3188 desired format. Changed callers.
3190 * stack.c (frame_info): Use filtered output, and indicate wrap
3191 points. Remove kludgy formatting designed to avoid line wrap.
3193 * utils.c (wrap_here): If the line is already full (because
3194 we had printed a long indent or long wrapped string), do an
3195 immediate newline-and-indent.
3197 * m68k-pinsn.c (print_insn_arg): Bugfix from
3198 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3199 instruction is incorrectly disassembled as bkpt #8.
3201 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3202 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3203 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3204 and then will dump core (sometimes). I traced it back to an
3205 uninitialized symfile_name in psymtab_to_symtab.
3206 (const_vol_complaint): Add quotes to message.
3207 (define_symbol): Only believe line number if gcc_compiled.
3208 Avoid allocating symbol if we will not return it.
3210 Add target strata support so that newly established targets go
3211 into their right place in the target stack (e.g. a new exec file
3212 doesn't wipe out the ability to access the running process).
3214 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3215 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3216 and initialize it properly in all the targets.
3218 * target.h: Document strata. Change return type of push_target.
3220 * target.c (nomemory): new function for dummy memory access.
3221 (tcomplain): Rename complain, now also used in symfile.c.
3222 (push_target): Push targets within strata. New return value shows
3223 whether new target is on top of stack or not. Always keep dummy
3225 (target_files_info): Ignore dummy target.
3227 * core.c (core_open): Warn user, and skip accessing file, if the
3228 core target is not the topmost target in the stack.
3229 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3232 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3233 target_ops, it doesn't belong there since we have no regs there.
3234 Change name of target from machine => memory to clarify.
3236 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3238 * Freeze version 3.93 for release.
3240 * Makefile.dist: Handle vx-share and nindy-share subdirs
3241 properly when building gdb.tar.Z.
3243 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3244 printed in various places, so I could change just one copy.
3246 * dbxread.c, coffread.c: Change references to bfd->iostream
3247 to cast to FILE *, now that BFD avoids needing types defined
3248 in other header files.
3250 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3252 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3253 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3254 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3255 (actually gcc -Wall).
3257 * dbxread.c: Remove first_global_sym, last_global_sym, since
3258 they are never referenced.
3260 * defs.h (baud_rate): Declare.
3261 main.c: Define it, and add the -b option to set it.
3263 * gdb-int.texinfo: Add text on how to define a new host or target
3264 architecture, prompted by Per Bothner's questions about MIPS
3267 * gdb.texinfo: Document "complaints". Change doc of -q since
3268 gdb no longer prints the copyright and blurb if you specify a file
3269 name to be debugged (just like Emacs). Add doc for Nindy-specific
3270 command line flags for specifying target serial port and such.
3271 Update copyright to 1991.
3273 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3274 has taken over for us the job of ripping up executable files. The
3275 crud caused Per Bothner's port to not compile.
3277 * infrun.c (normal_stop): Avoid printing "Program exited
3278 normally" if we are in batch mode. This allows a GDB which
3279 executes a program on a target system, to behave like a Unix
3280 command (input from stdin, output to stdout, no extraneous
3283 * main.c (main): Allow additional machine-dependent command line
3284 options to be specified with the ADDITIONAL_OPTIONS,
3285 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3286 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3287 processing to occur just before the main loop with
3288 BEFORE_MAIN_LOOP_HOOK.
3289 (main): If a "core file" argument is specified, and it is not a
3290 core file, try it as a process ID to attach.
3291 (symbol_completion_function): Attempt to cope with
3292 "show screen-" TAB, not very successfully. This needs more work,
3294 (batch_file): New function, returns whether we are reading
3295 commands from an interactive tty on stdin, or from somewhere else.
3296 Called by normal_stop since it doesn't get from_tty passed down
3297 to it like many commands do.
3299 * remote-nindy.c: Handle command line options for nindy
3301 (nindy_before_main_loop): Prompt user for tty name if they
3302 don't specify it before getting to the interactive command loop.
3304 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3305 and -r command line options. Also add hook before main loop
3306 to make it easy to specify a tty.
3308 * TODO: More things to do, one done.
3310 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3312 * dbxread.c: Make complaint() calls pass pointer, not struct.
3313 Add complaints about badly formatted C++ type information
3314 (const/volatile indicator, and parse errors resulting in
3315 error_type). Fix C++ virtual member fn comment.
3316 (read_struct_type): Avoid bumping pointer if we got a parse
3317 error; this prevents our walking beyond the end of a string.
3318 Terminate loop on null char as well as semicolon.
3319 (process_one_symbol): Fix the LBRAC fix so that it uses the
3320 last previous SLINE, FUN, or SO record's PC address. C++ debug
3321 symbols did not have SLINE records in a useful order compared
3322 to the LBRAC records.
3323 (define_symbol): Handle "catch" records.
3325 * symtab.c (check_stub_type): Added new complain
3326 `stub_noname_complain' and added a consistency check to
3327 keep the debugger from crashing when finishing from an
3328 exception frame. A real fix will be needed later.
3330 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3332 * infcmd.c (attach_command): Make global.
3334 * Makefile.dist (REMOTE_OBS): Make these compile by default,
3335 but make them easy to comment out. Perhaps later they should
3336 be enabled by what CPU you configure for? FIXME.
3337 (VERSION): Roll to 3.93.
3338 (pinsn.o): Remove rule for obsolete file.
3339 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
3341 Run down a problem that manifested by printing the wrong function
3342 name in stack traces of read_ofile_symtab. Turned out that the
3343 problem was the SunOS 4.1.1 (and previous) C compiler outputs
3344 the LBRAC symbol with an address in the *data* segment, which
3345 blew our binary search through the blocks.
3347 * dbxread.c: Use the complain() facility consistently to bitch
3348 about problems in the symbol file we are reading.
3349 (finish_block): Add code to check the nesting of the blocks;
3350 complain and Procrust them to fit if wrong.
3351 (make_blockvector): Check the order of the blocks, complain
3352 [but don't cope] if wrong.
3353 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
3354 symbols to be sure their PC value is greater than the last SLINE
3355 (line number) symbol we've seen, complaining and adopting the
3356 SLINE PC value if wrong.
3358 * symfile.h (struct complaint, complaint_root, complain,
3359 clear_complaints): Add.
3360 * symfile.c (complain, complaint_root, clear_complaints): Add
3361 facility to deal with non-fatal complaints and to regularize their
3363 (symbol_file_add): Clear complaint counters to allow new complaints.
3364 (initialize_symfile): Add 'set complaints' and 'show complaints'.
3366 * dbxread.c (dbx_symfile_read): Remember the address and size
3367 of the string table for the main symbol file, so we won't read it
3369 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
3370 to avoid reading the string table yet again. Lint.
3371 (throughout): Improve filtered output, including word wrap.
3372 (read_range_type): Improve Bothner's fix to handle other types too.
3374 * utils.c: Improve line wrap implementation. Handle unlimited
3375 width by making chars_per_line unsigned.
3376 (puts_filtered): New, easy, function.
3378 * defs.h (puts_filtered): add.
3380 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
3381 call the identical sort_symtab_syms() in symfile.c instead.
3383 * expread.y: Suggest the `file' command rather than `symbol-file'.
3385 * command.h (enum var_types): Add zinteger for seroable
3387 * command.c (do_setshow_command): Handle var_zinteger. Restructure
3388 nested if's into a switch.
3390 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
3391 we did not stop because of a breakpoint (it must have been for
3392 some other reason, like a "stepi"), so don't print anything.
3394 * symtab.c: Include <sys/types.h> all the time. Now that BFD
3395 doesn't include <sys/types.h>, old SunOS's require it for
3398 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
3400 A test port of gdb-3.92.6 to the Sony NEWS.
3403 Don't normally link in remote- or vx stuff.
3404 Some of it doesn't compile, and it wastes space for 99% of the users.
3405 Remove reference to no-longer-used HAVE_VPRINTF.
3406 Fixed BFD_DEP typo to BFD_DIR.
3408 Fix cast in arg to bfd_h_getlong.
3409 Make char *prefix be const.
3410 Fix how certain range types are mapped into builtin unsigned int types.
3412 Remove 2 #includes. They cause errors (on Sony, at least),
3413 and aren't needed (they wern't in earlier versions).
3415 print_address_symbolic should never demangle labels
3416 (since it prints *assembler-level* labels).
3418 [This was superseded by the change to printcmd below.]
3421 Add some "volatile" return types to avoid warnings.
3422 If MISSING_VPRINTF add vprintf function and not just macro
3423 (since vprintf is used in printcmd.c).
3425 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
3426 (The latter isn't grokked by some PCC-based compilers.)
3428 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
3430 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
3431 * nindy-share/coffstrip.c
3432 Added some forward declarations (otherwise, gcc complains
3433 about implicit extern redefined as static).
3435 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3437 Changes inspired by Per Bothner:
3438 * printcmd.c (print_address_symbolic): Take additional parameter
3439 specifying whether to demangle.
3440 (print_address): Pass in asm_demangle to control demangling.
3441 (print_address_demangle): New fn, takes explicit arg to control
3443 * utils.c: Add new vars demangle and asm_demangle, and let them
3445 (fputs_demangled): If !demangle, just print the argument.
3446 (fprint_symbol): If !demangle, just print raw symbol.
3447 * valprint.c (val_print): Call print_address_demangle rather than
3448 print_address, to cause demangling to depend on the global
3449 rather than assembler-level demangling setting.
3450 * WHATS.NEW, gdb.texinfo: Document.
3452 * main.c (show_command): Show all settings if no arg.
3453 (initialize_main): Make "info set" the same as naked "show".
3454 * command.c (cmd_show_list): Handle prefix commands in the
3455 list, and print the name of the setting as well as its English
3456 description and value.
3458 Allow gdb functions to specify where a line should wrap if it
3459 exceeds the size of a terminal line. Use it to make the output
3461 * utils.c (set_screen_width_command): New fn, mallocs a buffer
3462 of the right size when screen width changes.
3463 (set_screensize_command, screensize_info): Remove #if 0'd fns.
3464 (wrap_here): New fn, indicates a point in the output where we
3465 should wrap the line rather than just letting it overflow at a
3467 (fputs_filtered): Implement wrapping.
3468 (n_spaces): New fn, returns a pointer to N spaces.
3469 (print_spaces_filtered): Use n_spaces.
3470 * defs.h (n_spaces): Declare.
3471 * stack.c (print_frame_info): Wrap with 4-space indent after
3472 fn name and before filename and line number.
3473 * printcmd.c (print_frame_args): Wrap with 4-space indent
3474 before each argument name is printed.
3475 * valprint.c (value_print): Wrap with no indentation before
3477 (val_print_fields): Wrap with indentation relative to nesting
3478 level before each field name.
3479 (val_print): Wrap with nesting indentation before array elements.
3480 * command.c (do_setshow_command): Avoid extra newlines,
3481 wrap with 4-space indent around values printed, end with period.
3482 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
3484 * breakpoint.c (breakpoint_1): Implement addressprint for
3485 "info breakpoints" display. Change file name and line number
3486 format to " at file:nnn" rather than " (file line nnn)".
3487 * gdb.texinfo: Document.
3490 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3492 Frozen for gdb-3.92.6 release.
3494 README, WHATS.NEW: Update for 3.92.6 release.
3496 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
3497 coffread.o from configs since it is now built by default.
3498 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
3499 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
3500 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
3501 from configs since it is now built by default.
3503 Makefile.dist: Update for release 3.92.6. Handle files that
3504 have been moved to ../include, ../getopt, or ../bfd. Add
3505 saber.suppress and tests directory. Add config.status to
3506 the release (it will say "none").
3508 coredep.c: Minor formatting fixes.
3510 These changes were made in early December but only checked in now:
3511 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
3512 nindy-share/nindy.c: lint
3513 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
3514 register values coming back from the target; we store values
3515 in target byte order everywhere.
3517 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
3519 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
3521 * valprint.c (cplus_val_print, val_print_fields): New functions,
3522 which print C++ objects. They conspire to avoid printing a
3523 virtual base class more than once, following all the twists and
3524 turns of C++ virtual base rules.
3525 (val_print): Call the above rather than do it by hand.
3527 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
3528 symbol file, not for added files like shared libs. This really
3529 needs to be generalized to a timestamp per file.
3531 * core.c (cleanup_core): Avoid coredump if no core file.
3533 * config.gdb: Accept -host or -target in place of +host or
3536 * coffread.c (find_linenos): Avoid desupported BFD interface
3537 to line numbers. We still read them manually rather than using
3538 BFD's "generic" features.
3540 * gdbrc.tex, threecol.tex: Add GDB reference card and its
3542 Makefile.dist: Add refcard to OTHERS list for creating tar files.
3544 * Makefile.dist: Eliminate use of $< in explicit targets.
3546 * readline/Makefile: Use $< rather than $*.c, which does not
3547 include the VPATH in GNU Make.
3549 * tconfig/i960-bout, tconfig/i960-coff: These are identical
3550 copies of tconfig/i960, added for global configuration
3551 compatability. All i960 versions can read both coff and b.out.
3553 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
3554 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
3557 * TODO: Think of more things to do.
3559 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
3561 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
3562 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
3563 64-bit float conversion.
3565 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
3566 equivalent to sun?os4 so global config works.
3568 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
3570 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
3572 * main.c: Only declare linesize once; declare pagesize not at
3573 all, since it is never used.
3574 (main): Clear newly allocated line before it is used.
3576 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
3578 Further stabilization for the Intel 960.
3580 * Makefile.dist: Parameterize the location of the "include"
3581 and "bfd" directories, as well as "getopt". Add symfile.c.
3582 Link in both dbxread and coffread. Fix up "make depend" to
3583 rewack the locations of include, bfd, and getopt in its output.
3585 * README: Document moving include files, improve some of
3588 * coffread.c: Move common code out to symfile.c. Change
3589 symbol_file_command style interface to use new *_symfile_init
3590 and *_symfile_read interface under BFD. Use BFD internal
3591 info to locate line table, symbols, etc.
3593 * core.c (core_fetch_registers): Rename to get_core_registers
3594 to avoid confusion with fetch_core_registers.
3595 (register_addr): Move to coredep.c, which is already machine
3596 dependent. This leaves core.c pretty clean of dependencies.
3598 * coredep.c (register_addr): Accept this routine from core.c.
3600 * dbxread.c: Move common code (with coffread.c, etc) into new
3601 symfile.c. Each psymtab now contains a pointer to the
3602 format-dependent function that knows how to read it in. Make
3604 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
3605 (process_one_symbol): Add code to complain about a "compiler bug
3606 we muzzle here", if we actually see it.
3608 * eval.c (evaluate_subexp): Insert missing "break" statements
3609 in code that determines whether a variable is an lvalue in
3610 memory, register, or whatever. I detected this via a compiler
3611 bug in which it *almost* mashed out the whole switch statement.
3613 * gdb-int.texinfo: Add minor sections on configuring gdb for
3614 release, and about the README file.
3616 * infcmd.c (registers_info): Fix formatting somewhat. Still
3617 not as pretty as before, but it handles byte swapping.
3619 * remote-nindy.c: If data cache routines are interrupted while
3620 waiting for the remote end, be sure that any uninitialized cache
3621 blocks are on the free list, not on the valid list!
3623 * symfile.h: Flesh out this header file with all the various
3624 routines and variables that have been merged in from dbxread.c
3625 coffread.c, and symtab.c to symfile.c.
3627 * symfile.c: New file, containing code common to dbxread.c,
3628 coffread.c, and some code from symtab.c. All generic code for
3629 reading symbol files should be in here now.
3630 (unrecord_misc_function): Remove unused function.
3632 * symtab.h: Remove file-reading things to symfile.h.
3634 * symtab.c: Remove file-reading things to symfile.c.
3636 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
3637 to decode i960 fault types.
3639 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
3640 target.c: Change type of the "resume" function from int to void,
3641 since its result was never used.
3643 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
3645 * main.c: Replace "stupid" with "caution"; you now "set caution
3648 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
3650 * infcmd.c (do_registers_info): Call val_print to deal with the
3651 byte order of the registers being printed. FIXME, this makes
3652 the formatting of the output uglier.
3654 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
3655 defined, call it for signals the debugger doesn't itself use.
3656 The i960 uses this for more detailed fault information.
3658 * remote.c (remote_open): If arg is null, print help rather than
3661 * sparc-xdep.c (register_valid): Avoid declaring size, since
3662 various modules will think of various sizes depending on the
3663 architecture of their tm-file. FIXME, we need protection against
3664 actually entering one of those modules, which would clobber
3665 storage if not for the target architecture compiled into gdb.
3667 * stack.c (up_command, down_command): Always print the frame
3669 (up_silently_command, down_silently_command): New commands
3672 * i960-pinsn.c (reg), i960-tdep.c: Lint.
3674 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
3675 more parameters than it used to.
3677 * findvar.c (registers): Increase slop to 256 bytes, which should
3678 protect us against even most RISC machines with large register
3680 (locate_var_value): Move declaration inside related ifdef.
3682 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
3683 throughout, to avoid throwing away buffered input from the board.
3684 (nindy_wait): Supply_register takes addr_of_value, not value.
3685 (i960_print_fault): Renamed from i80960_fault.
3686 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
3687 (nindy_store_registers): Avoid regs_changed stuff, just stuff
3689 (nindy_create_inferior): Don't bother to write PC_REGNUM since
3690 we can set the PC in the call to proceed(). Unpush nindy_ops
3691 before pushing it on top, to avoid message to user. Eliminate
3692 commentary from Unix machines that just misleads here.
3693 (reset_command): Fix error message to suggest target command.
3695 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
3697 Release 3.92.5 as frozen.
3699 Stabilize the merged release...with help from lint, Saber C,
3702 Everywhere: Add include files needed to declare return types
3703 of functions called.
3705 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
3707 * breakpoint.h: Add undeclared breakpoint functions, and some
3708 functions for display handling since I couldn't think of a better
3711 * breakpoint.c (insert_breakpoints): Make code for disabling
3712 shared library bkpts more likely to work. It's used when we
3713 rerun a program and stop before the shared library has been
3715 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
3716 cast from pointer, so it squeezes through catch_errors.
3717 (bpstat_stop_status): Fix logic broken some time ago. We now
3718 always create a bpstat if the stop address matches a breakpoint,
3719 even if we don't stop there -- just like the old code used to do
3720 before I got my fingers into it (sigh).
3721 (breakpoint_1): Print "ignore count" after "stop only if"
3722 condition, since that's how it actually works.
3723 (mention): Handle watchpoints as well as breakpoints.
3724 (watch_command): use set_raw_breakpoint and mention to do most
3725 of the work (and initialize all the fields!). Only pass one
3726 arg to parse_c_expression, since that's all it takes.
3728 * command.c (not_just_help_class_command): Rename arg to args
3729 since we ignore "unused argument" warnings on vars named "args".
3730 inflow.c (child_terminal_info): ditto.
3731 infptrace.c (kill_inferior): ditto
3732 main.c (catch_errors, version_info, quit_command, pwd_command,
3733 source_command, dump_me_command, editing_info,
3734 set_history_size_command, set_history, show_history,
3736 stack.c (locals_info): ditto
3737 target.c (target_files_info): ditto
3738 valprint.c (set_input_radix, set_output_radix): ditto
3740 * core.c: Remove old variables for handling core and exec file
3741 sections (data_start, data_end, stack_start, stack_end,
3742 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
3743 text_end, exec_data_start, exec_data_end, text_offset,
3744 exec_data_offset, data_offset, stack_offset). They're
3745 superseded the more general build_section_table and
3747 (get_exec_file): Mention the `file' command.
3748 (read_memory_check): Rename to memory_error, and only call it
3749 in the case of an actual error.
3750 (read_memory, write_memory): call memory_error.
3751 (core_fetch_registers): Register section name is ".reg".
3753 coredep.c: Remove a bunch of crud now that all this file does
3754 is pull the registers out of a core file.
3755 (fetch_core_registers): Rewrite to actually work, I hope.
3757 dbxread.c: Use a.out.gnu.h, not system a.out, now.
3758 Replace index() with strchr(). Remove all the pre-BFD macro
3759 definitions for accessing the symbol file.
3760 (struct dbx_symfile_info): Encapsulate the information that
3761 dbx_symfile_init needs to pass to dbx_symfile_read in this
3764 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
3765 dbx_symfile_discard): Rearrange symbol file reading to divide
3766 the format-specific part from the format-independent part,
3767 leaving the format-independent part such as file name expansion
3768 and opening in symtab.c. This replaces
3769 partial_symbol_file_open and partial_symbol_file_read.
3770 Symbol_file_read, add_file, add_file_target_command,
3771 add_file_addr_command move to symtab.c. Pass an explicit
3772 "mainline" flag for when reading the main symbol table, rather
3773 than relying on the offset address to be zero or nonzero.
3775 (dbx_symfile_read): Don't allow void *'s to be printed as
3777 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
3778 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
3779 macro" debug version really work.
3780 (read_dbx_symtab): Remove unref'd parameter inclink.
3781 Avoid swapping N_SLINE symbols, for speed.
3782 Merge N_TEXT!N_EXT case with the other external symbol
3783 definitions' case. Add comments.
3784 (start_psymtab): Allocate the symfile name in the psymtab on
3785 the psymbol_obstack, rather than using the caller's storage.
3786 (end_psymtab): Only allocate a dependencies list if there are
3788 (psymtab_to_symtab_2): Use BFD when reopening file to read
3789 its symbols for real.
3790 (read_struct_type): Add FIXME comments where it needs work
3792 (read_huge_number): Add FIXME about overflows.
3793 (read_range_type): Add FIXME about comparing a long to 1<<32.
3795 * coffread.c: Minor changes to move things closer to the new
3796 regime with symtab.c and dbxread.c Major work is still needed
3799 * exec.c (exec_file_command): Remove old variables (see core.c
3801 (xfer_memory): If memory transfer is right at the end of a
3802 section, don't lose.
3804 * findvar.c (get_saved_register): If value is in a real
3805 register, LVAL is lval_register, not lval_memory.
3807 frame.h: Declare print_sel_frame and record_selected_frame.
3809 gdb-int.texinfo: New file, for GDB internals documentation.
3810 Very simple, unformatted doc of cleanups is there for now.
3812 gdbcore.h: Remove obsolete variables that described a.out
3813 section addresses and offsets. (See core.c above.)
3814 Declare fetch_core_registers and registers_fetched.
3816 getopt.c: Declare char *alloca(); even on SPARC.
3818 infcmd.c (run_command): Call target_kill rather than
3820 (step_command, next_command, stepi_command, nexti_command):
3821 Declare from_tty parameter even though we don't use it.
3822 (run_stack_dummy): argument BUFFER is a char array, not
3823 a pointer to REGISTER_TYPE.
3824 (finish_command): using_struct_return needed a value *,
3825 not a struct symbol *.
3827 * infptrace.c (child_xfer_memory): To avoid dependency on
3828 where sections are in memory, try PT_WRITE_D and if that fails,
3829 try PT_WRITE_I. Most Unixes don't care which you use.
3831 * infrun.c (step_resume_break_shadow): Change to array to
3832 match other breakpoint shadow storage.
3833 (clear_proceed_status): Pass address of bpstat to
3834 bpstat_clear, not the bpstat itself.
3835 (child_create_inferior): FIXME comment about if the child
3837 (start_inferior): Remove old function.
3838 (child_open): Use target_kill rather than kill_inferior.
3839 (wait_for_inferior): Ditto.
3840 (insert_step_breakpoint, remote_step_breakpoint): Use
3841 new step_resume_break_shadow.
3843 * inftarg.c (child_wait): If all child processes die,
3844 pretend that the one being waited for exited with signal 42.
3846 * main.c (command_line_input): When scanning for comments,
3847 don't coredump on unclosed quotes.
3848 (quit_command): Use target_kill rther than kill_inferior.
3849 (_initialize_main): Rename class_user from "user" to
3852 * printcmd.c (print_command_1): Initialize "fmt" if no format
3853 is specified by the user.
3854 (print_frame_args): Only add to args_printed if we are
3855 actually fetching args from the stack (avoiding undefined
3857 (_initialize_printcmd): Remove bogus \{ from string.
3859 * remote-eb.c (eb_open): Avoid coredump on no argument.
3861 * remote-nindy.c: Bring out of Intel environment into new
3862 target environment. Remove all conditional compilation on
3863 I80960. Massive hacking throughout.
3864 (nindy_xfer_inferior_memory): New routine stolen from
3866 (nindy_create_inferior): New routine pieced together, probably
3867 not quite working yet.
3868 (nindy_ops): New target_ops struct for nindy.
3870 * remote-vx.c: Use write_memory rather than target_write_memory
3871 to get error checking.
3872 (vx_add_file_command, vx_open): Use symbol_file_add rather than
3874 (vx_create_inferior): Use target_terminal_ours...
3876 * signame.c (_initialize_signame): Always initialize, since
3877 we need the table for things other than psignal.
3879 * solib.c (solib_add): Use symbol_file_add, not add_file.
3880 (solib_address): Return boolean result rather than struct
3881 pointer which nobody else knows the type of.
3883 * sparc-tdep.c, valops.c: Use write_memory rather than
3884 target_write_memory, to get error checking.
3886 * stack.c (locals_info, catch_info, args_info,
3887 get_selected_block, frame_command, up_command): Use
3888 target_has_stack, rather than have_inferior_p or
3891 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
3893 * symfile.h: New file, defining the interface between the
3894 generic and object-file-specific symbol reading code.
3896 * symtab.c: Move generic symbol-reading interface to symtab.c,
3897 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
3898 table to map BFD targets to symbol-reading modules in GDB.
3899 Change index to strchr.
3900 (lookup_struct_elt_type): Use error() rather than hand-made
3901 simulations thereof.
3902 (lookup_partial_symbol): Speedup slightly when length == 0.
3903 (symbol_file_add): New function.
3904 (symbol_file_command): Call it.
3905 (symfile_open, symfile_init): New function.
3906 (add_file_target_command, add_file_addr_command): moved from
3909 * target.c (target_command): use target_kill.
3911 * target.h (target_files_info): Don't declare, never called
3914 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
3915 files to determine stack end address.
3917 * valarith.c (value_x_binop, value_x_unop): Change error message
3918 to be more useful. Pass proper argument to value_struct_elt.
3920 * valops.c (value_assign): FIXME comment that long long
3921 bitfields will break here.
3923 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
3924 Update `make saber_gdb' to work better.
3926 * TODO: A woman's work is never done.
3928 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
3929 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
3930 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
3931 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
3932 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
3933 valops.c, valprint.c, exec.c: Lint.
3936 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
3938 Continuing Intel 960 port merge of GDB.
3940 * Makefile.dist: Merge i960 "nindy-share" files. Rename
3941 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
3942 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
3943 Wack over "make depend" so it handles files in subdirectories
3944 vx-share, nindy-share, bfd, and in the current directory.
3946 * blockframe.c (get_prev_frame_info): Remove fatal error
3947 if stack not defined.
3949 * core.c (core_open, core_detach): New functions that handle
3950 the old "core-file" command as "target core" and "detach" instead.
3951 (core_file_command): Call them.
3952 (core_xfer_memory): Use common routine xfer_memory.
3954 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
3955 dbxread now uses bfd for everything but symbol reading itself.
3956 BFD internals are used to drag out the relevant file offsets.
3957 (partial_symbol_file_open): Change args all around for BFD.
3959 * symtab.c: Rename "value" to "val" everywhere, so we can
3961 (symbol_file_command): New command, moved from dbxread.c
3962 and coffread.c. It uses BFD to read the file, then vectors
3963 based on its type, to dbx or coff symbol readers.
3964 * symtab.h: Extern a few vars for symbol_file_command.
3966 * target.h: Breakpoint takes a char * save area, not a char **.
3968 * valprint.c (val_print): When unpacking bitfields, offset
3969 the address in gdb of the value, if it is declared with a shorter
3970 type. Remove the last "runtime kludge test" of host byte order.
3972 * utils.c: Remove old my_bfd_read routine.
3974 * stack.c (frame_info): Use target_has_stack. Print program counter
3975 register's actual name rather than "pc", since it's called the
3976 "ip" (instruction pointer) on the i960 (sigh).
3978 * target.c (target_command): Add command for selecting a target
3979 type and calling its open routine. This is used for initiating
3980 communication with a particular target, in a generic way.
3982 * tm-i960.h: Update for modern gdb. Remove semicolons from
3983 various macros. Handle reading struct return convention, and
3984 error-out attempts to return structs with the "return" command.
3985 Be sure gdb doesn't think we know how to call functions in the
3988 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
3989 to i960_xxx in lower case.
3990 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
3991 not being defined yet.
3993 * remote.c (remote_open): Call start_remote to initialize
3994 wait_for_inferior during open.
3995 (remote_xfer_inferior_memory): Return length written rather
3998 * remote-vx.c (target_command -> vx_open): Use new generic
4000 * remote-eb.c, inftarg.c, exec.c: ditto.
4002 * infrun.c: Fix comments.
4003 (attach_program -> child_open): Use new generic target command.
4004 (wait_for_inferior): Clear saved register values before target_wait,
4005 so target_wait can set some of them if convenient.
4007 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4008 Return success indicator, not void.
4009 (child_xfer_memory): Avoid fetching initial word if we'll
4010 overwrite it anyway.
4012 * infcmd.c (attach_command): Use new generic target open routine.
4013 (_initialize_infcmd): Update doc on attach and detach commands.
4014 (do_registers_info): Merge in a byte-order problem as a FIXME
4017 * findvar.c (find_saved_register): Avoid problem in current frame.
4018 (read_relative_register): Ditto.
4019 (write_register): Convert byte order on the way out.
4021 * exec.c (file_command): Add.
4022 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4023 (xfer_memory): Common function between core_xfer_memory and
4025 (exec_xfer_memory): Use it.
4027 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4029 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4030 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4031 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4033 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4035 Merge Intel 960 port of gdb, continuing...
4037 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4038 symbol_file_command): Pass from_tty arg to hush 'em up.
4040 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4041 Add magic numbers for 960 COFF format.
4043 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4045 Merge Intel 960 port of gdb, from Intel "1.2" release.
4047 CHANGE_LOG entries from their port, which was based on
4050 Thu Sep 6 11:02:22 PDT 1990
4051 Remove temp file if download is interrupted.
4053 Wed Aug 1 09:08:33 PDT 1990
4054 Now uses binary protocol to talk to NINDY.
4055 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
4056 Times out after 5 seconds when trying to talk to NINDY.
4058 Tue May 29 12:54:49 PDT 1990
4059 Added variable baud rate (-b switch).
4060 Source code reorganization.
4062 Thu Apr 26 11:09:55 PDT 1990
4063 More cleanup of batch mode; specifically, execute "-s", "-e", and
4064 "-se" switches as soon as they are encountered on the invocation line.
4066 Fri Apr 20 13:47:15 PDT 1990
4069 Thu Apr 19 09:54:28 PDT 1990
4070 Add 'reset' command.
4072 Wed Apr 18 09:48:07 PDT 1990
4073 After opening remote tty, wait for 1 second to go by without input
4074 from it before trying to talk to NINDY (fixes problems with the
4075 Heurikon HK80/V960E).
4077 Mon Apr 4 16:33:05 PDT 1990
4078 Some output was not being suppressed in 'batch' mode.
4080 Thu Mar 22 15:31:11 PST 1990
4081 Ask user if old symbol table should be deleted when new file is
4084 Allow user to run a program downloaded before gdb960 was brought up.
4086 Correct "exec-file" help message for i80960 context.
4088 Correct bug in calculating user space address: could occasionally
4089 corrupt user program.
4091 Make sure to zero low-order bits in rip's because of bug in 960CA
4092 A-step part: could cause operation faults when "next"ing across
4095 Correct bug that made it impossible to get source line numbers for
4096 code loaded at addresses higher than 0x7fffffff.
4098 Wed Jan 10 12:43:22 PST 1990
4099 Open remote tty for exclusive use.
4101 Fri Jan 5 12:14:42 PST 1990
4102 Correct disassembly (CA manual was right after all):
4103 opcode for sysctl is 0x659
4105 Mon Oct 23 12:03:04 PDT 1989
4106 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4108 Mon Oct 16 14:15:09 PDT 1989
4109 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4111 Mon Oct 2 15:56:31 PDT 1989
4113 Added 960CA disassembly support.
4115 To simplify maintenance:
4116 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4118 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4119 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4120 - made disassembly interface identical to that in gdmp960.
4124 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4126 * target.h: Allow targets to stack. Add target_has_memory,
4127 _registers, etc. Restructure memory access and "info files"
4128 to walk the target stack.
4129 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4130 target.c: Change tables to match target.h.
4131 * inflow.c (child_mourn_inferior): pop child_ops.
4132 (generic_mourn_inferior): Use new has_stack flag.
4133 * infptrace.c (child_xfer_memory): New memory regime.
4134 * inftarg.c (child_files_info): New "info files" regime.
4135 * remote-eb.c: New memory regime, new info files.
4136 * remote-vx.c: New memory regime, new info files. Now use
4137 separate targets for VxWorks attachment to machine, and
4138 actually running a process under VxWorks, since one has
4139 stack & execution & regs and the other doesn't.
4140 * remote.c: New memory regime, new info files.
4141 * sparc-xdep.c (fetch_core-registers): New memory regime.
4142 * target.c: New routines and support for stacked targets,
4143 new memory regime, new info files regime.
4146 Generalize section handling for an arbitrary number of sections,
4147 including use of the new BFD (binary file) library.
4148 * gdbcore.h: Add struct section_table.
4149 * exec.c (build_section_table): Iterate all sections and
4150 record what gdb needs to know about them.
4151 (exec_command): Use it.
4152 (exec_xfer_memory): Use the table.
4153 (exec_files_info): Print the table.
4154 * core.c (core_file_command, core_xfer_memory, core_files_info):
4156 * source.c (find_source_lines): Use bfd_get_mtime.
4157 * dbxread.c: Quick changes to make it compile with new BFD.
4158 * utils.c (error): Avoid using bfd_error in generic routines.
4160 * core.c (core_fetch_registers): Get from the ".regs" section of
4162 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4164 * inferior.h (attach_flag): Export.
4165 * infcmd.c (run_command): use new target_create_inferior.
4166 * infrun.c (child_create_inferior): Don't return result.
4167 * Makefile.dist (VERSION): 3.91.4.
4169 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
4171 * breakpoint.c (bpstat_num): Handle breakpoints which have
4172 since been deleted, such as temporary breakpoints.
4173 infcmd.c (program_info): ditto.
4175 * core.c (core_file_command): Display the frame where the core
4180 * remote-vx.c (target_command): Merge in target command from
4181 targ-vx.c. A few other cleanups.
4183 * TODO, Projects: Lots more stuff to do...
4185 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4187 Massive changes to wall off the remote-debugging interface
4188 behind a function vector. The port to handle VxWorks targets
4189 is also part of this.
4191 All files: Replace references to renamed functions,
4192 remove references to remote_debugging, remove references to
4193 have_include_file, have_core_file in favor of target_has_stack,
4194 target_has_memory, etc.
4196 * Modularize the breakpoint interface.
4197 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4198 a breakpoint instruction.
4199 breakpoint.c: struct breakpoint's shadow_contents now sized as
4201 (insert_breakpoints): Vector to target to install breakpoints.
4202 (remove_breakpoints): Vector to target here too.
4203 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4204 sparc-tdep.c (single_step): Use new breakpoint interface for
4205 the single-step breakpoints.
4206 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4207 New file, contains routines to insert and remove breakpoints by
4208 reading out the old contents and later replacing them. This is
4209 how ptrace breakpoints work, and many remote systems as well.
4211 * tm-vxworks68.h: New config file, overrides a few things for
4212 Wind River's preferences.
4214 * target.h: New file, for transfer vector used to talk to the
4215 inferior (child, attached, core, exec, remote, etc). All accesses
4216 to the thing being debugged should come through these vectors.
4217 target.c: New file, routines to handle transfer vector.
4218 (various files): Add transfer vectors XXX_ops for the various
4219 targets and pseudo-targets (core files, etc) we support.
4221 * breakpoint.c (bpstat_stop_status): Further explorations of
4222 watchpoints and why things don't work all the time.
4223 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4225 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4226 the local gdbinit if it doesn't already have it.
4228 * core.c (core_ops): add and install.
4229 Allow core debugging without exec file.
4231 * dbxread.c (free_and_init_header_files): Merge two fns.
4232 (end_symtab): Free named symbol table when a new version comes in.
4233 (read_dbx_symtab): Relocate all kinds of symbols with base
4234 address. First step toward handling different text, data, bss
4236 (add_file_addr_command): Renamed add_file_command.
4237 (add_file_command): Vector to remote handler.
4238 Add "load" as an alias for "add-file" command.
4240 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4241 non-returning functions.
4243 * exec.c: Add exec_ops, and push it as a target when an exec
4246 * infcmd.c (run_command): Pass executable file name and arg list
4247 separately when starting an inferior. Permit "run" when no exec
4248 file is specified, for VxWorks.
4249 (detach_command): Move to child_detach in inftarg.c.
4251 * inftarg.c: New file. Unix-child-specific routines, and the
4252 child_ops structure.
4254 * inferior.h (registers): Export "registers" as the way for
4255 target dependent register handlers to find gdb's local copy of
4256 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4257 since it is now used by places that want wait_for_inferior to
4258 handle the grunge but want to see every trap from the inferior.
4260 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4261 Eliminate remote_debugging hooks in terminal handling.
4263 * infrun.c: Replace start_inferior with child_create_inferior.
4264 Move all the hair of Unix shells and ptrace idiosyncracies into
4265 child_create_inferior, so remote handlers don't have to deal.
4266 Remove running_in_shell. Rename stop_after_attach to
4267 stop_soon_quietly, and use it in a few other places where we want
4268 to just call wait_for_inferior and get control back on the first
4269 trap. trap_expected now never takes a value > 1.
4270 (init_wait_for_inferior): Initialize static vars when a new
4273 main.c (gdbinit): Add new hook for .gdbinit file name, let
4274 it be overridden by config files as GDBINIT_FILENAME.
4275 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4276 Both of these are used for VxWorks gdb.
4278 mcheck.c: rename include file "gmalloc.c" to avoid problems
4279 with system include file "malloc.c".
4281 param-no-tm.h: New include file, same as param.h but does not
4282 include the default "tm.h" file. This is used in files where
4283 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4285 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4287 remote-vx.c: New file, VxWorks remote debugging support. Uses
4288 RPC routines that are shared with the target system, in directory
4291 remote.c: Vectorize remote interface.
4293 source.c: Globalize source_path, and make an alias "l" for "list"
4294 since we now have the "load" command.
4296 sparc-xdep.c: Use new param-no-tm.h.
4298 symmisc.c (free_named_symtab): Add new function from Wind River.
4299 However, ifdef it out for now while we think about what it should
4302 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4304 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4305 non-Unix-children handle this with their own code in the target
4308 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4309 source and target lists. Add vx-share to default list of include
4310 directories. Add new files to src and target lists: mem-break,
4311 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4312 ${srcdir} versions of munch and createtags are used.
4314 * valops.c (find_function_addr): Split out of call_function.
4315 (call_function_by_hand): Rename call_function; this function
4316 calls functions in the target by laboriously patching the target
4317 word-by-word with the right stack, args, regs, etc.
4320 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
4322 Handle AMD 29000 a bit better.
4324 * remote-eb.c (readchar): Mask received char log to make it readable.
4325 (remote_start): Pass arguments down to executing program.
4326 Make startaddr unsigned.
4327 infrun.c (start_inferior): Accept args, pass them to
4329 infcmd.c (run_command): Pass args down to start_inferior.
4331 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
4332 the target object file format.
4333 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
4335 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
4336 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
4338 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
4340 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
4341 * TODO: We did a few things, we have more to do though.
4343 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
4344 * inflow.c (inferior_died): Clear deferred stores.
4346 * Debug problems with dummy frames and calls to the inferior.
4347 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
4348 * sparc-tdep.c (do_restore_insn): Simplify.
4349 (sparc_frame_find_saved_regs): Simplify and fix what we find.
4350 (sparc_push_dummy_frame): Simplify and fix what we push.
4351 (sparc_pop_frame): Slightly more hair here, deciding whether
4352 we are restoring a saved PC or returning to a return address in %i7.
4353 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
4355 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
4356 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
4357 * obstack.h (chunkfun): ditto.
4358 * defs.h (xmalloc, xrealloc): ditto
4360 * utils.c (quit): Grab the terminal from the child if necessary.
4362 * inflow.c (term_status_command): Rename to term_info, change
4365 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
4366 (is_delayed_branch): Speed up.
4367 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
4368 Still missing some float ops, and needs testing.
4370 * Support for input and output radixes other than base 10
4371 * defs.h (input_radix, output_radix): Declare.
4372 * expread.y (yyparse, parse_number): Handle changes of input
4373 radix, and ambiguous names-or-numbers in radixes >10.
4374 * printcmd.c (print_scalar_formatted): Print formatted hex
4375 numbers in varying column widths.
4376 * valprint.c (val_print): Use output_format to print scalar ints.
4377 (set_input_radix, set_output_radix, set_radix): Create.
4378 (set_output_radix): Set output_format from output_radix.
4379 (_initialize_valprint): add `set radix' but leave the others off.
4381 * main.c (execute_command): Let stupid questions be turned off.
4382 (_initialize_main): Handle "set stupidity", etc.
4384 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
4385 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
4387 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
4389 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
4390 bfd stuff is still screwed up, but with some manual work, it
4393 * breakpoint.c (bpstat_do_actions): Start over if a command
4394 proceeds the inferior, since the inferior will have stopped and
4395 will need to have its new stop-actions taken care of.
4397 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
4398 compiler fits, simplify it.
4400 * gdb.texinfo (directory command): Doc new dir command.
4401 source.c (directory_command): "dir" now puts things on the front
4402 of the path, moves dups up front, and handles multiple names
4403 on the command line, inserting each one in order. It also
4404 blows away cached line and full_filename info.
4406 * stack.c (backtrace_command): Skip "more stack frames follow"
4409 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
4410 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
4411 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
4412 The only odd one was Gould NP1, which had defined vprintf to
4415 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
4416 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
4417 variable, inspect_it.
4418 valprint.c (print_string, val_print): Use the global inspect_it
4419 to indicate whether to print in Epoch style or normal style.
4421 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
4423 * printcmd.c (call_command): add an alias for the "print" command
4424 which runs expressions and doesn't print the result if void.
4425 (print_command_1): implement it.
4427 * command.c: Remove #if 0'd code. Initialize all the fields
4428 in add_cmd (). Rename do_nothing_command to
4429 not_just_help_class_command, and make it externally visible.
4430 command.h: add user_commands to struct.
4431 * main.c (define_command): Don't overload c->function with a char
4432 string as well as a function pointer.
4434 * eval.c (evaluate_subexp): Reinstall tiemann changes to
4435 calling convention of value_struct_elt () that got dropped in
4438 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
4439 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
4441 * tm-sparc.h (POP_FRAME): replace some constants with defines.
4443 * sparc-xdep.c (store_inferior_registers): defer stores to regs
4444 until a good time (e.g. when we are about to run the child),
4445 saving ptrace calls.
4446 * infrun.c (proceed): handle DO_DEFERRED_STORES.
4447 * tm-sparc.h: define DO_DEFERRED_STORES.
4449 * sparc-xdep.c (store_inferior_registers): when storing float
4450 registers, don't store stack regs too. When storing the SP,
4451 however, DO store the stack regs too. This fixes a bug in which
4452 the dummy frame is not recognized when a call_function finishes,
4453 because its frame pointer (in the stack regs) was never
4455 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
4456 even though we don't know how to read them from an inferior.
4457 valops.c (call_function): Comment about storing SP.
4459 * infrun.c (save_inferior_status): Save away the original bpstat
4460 chain so it can be restored later. Install the copied version for
4461 use by whoever saved the status. It will be blow away by
4462 restore_inferior_status, and the original chain restored. This is
4463 important for people who have pointers into the original.
4465 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
4466 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
4467 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
4470 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
4472 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
4473 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
4474 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
4476 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
4478 * Merge Mike Tiemann's multiple inheritance changes from Sun.
4479 Store the baseclasses in a type struct starting from array element
4480 0 rather than from the unusual array element 1.
4482 dbxread.c: the above.
4483 (virtual_context): Add
4484 Read new debug information about which virtual function table
4485 a virtual function is from, and store it in fn_field.fcontext.
4487 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
4488 TYPE_FN_FIELD_STATIC_P.
4490 symtab.c: the above.
4491 valops.c: the above. Handle pointer casts of object *'s.
4492 (search_struct_method): Add.
4493 (value_struct_elt): First arg is now a pointer to a value, and is
4496 valprint.c: the above.
4497 values.c (value_virtual_fn_field): Add type arg. Handle
4498 offsetting to the proper object when calling virtual fns.
4500 (baseclass_addr): Add valuep arg.
4502 * README: Document the current state of BFD config (missing).
4503 * TODO, ChangeLog, Makefile.dist: Roll version.
4504 * WHATS.NEW: Add summary of changes since 3.5.
4506 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
4508 * dbxread.c (read_struct_type): Clear bit vectors whenever
4510 symtab.c (B_CLRALL): define.
4512 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
4513 using == rather than =. Huh... This fixes the dreaded problem
4514 wherein builtin_type_int becomes TYPE_CODE_FLT.
4516 * core.c (info_files): Show the inferior pid.
4518 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
4519 already knows how to look in the source directory.
4521 * Remove psymtab hair from many places. Remove duplicated code
4522 for searching symbol tables. Hide psymtabs from most places.
4523 Make it fast to get from a psymtab to its symtab.
4525 blockframe.c (blockvector_for_pc): Remove psymtab hair.
4526 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4527 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4528 dbxread.c: export psymtab_to_symtab, make it work if called N times.
4529 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
4530 new symtab completely. New psymtabs get symtab pointer
4531 initialized to zero. Remove MI warning printf.
4532 symtab.h: Comments. Add psymtab to symtab pointer.
4533 (PSYMTAB_TO_SYMTAB): New macro.
4534 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
4535 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
4537 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
4539 (print_frame_info): Avoid special-casing symbols that have not yet
4542 * source.c (open_source_file): Quick path if we have already
4543 located the source file by its full name.
4545 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
4546 find_pc_psymtab. When a name is found in the misc function
4547 vector, search the symbol table for its mangled name, not the
4548 name that the user typed.
4550 * bfd.h: Fix missing comment terminators, make #endifs match.
4552 * valarith.c (value_less): Handle unsigned int comparisons.
4553 Add FIXME about pointer compares, which assume host and target
4554 pointers are the same.
4556 * command.c (do_nothing_command): lint
4557 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
4558 fix comments on debug symbol format for visibility. Actually set
4559 visibility of symbols.
4560 main.c (echo_command): lint; use <readline/history.h>.
4561 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
4562 obstack.h (_obstack_blank): Rearrange pointer math to avoid
4563 pointing past end of allocated memory; saber complains.
4564 obstack.h: Declare the external functions that we use.
4565 valarith.h: use <string.h>
4566 solib.c (solib_add): lint.
4568 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
4570 * main.c (initialize_main): Default info_verbose to off, now that
4571 symbol reading is fast.
4572 (quit_command): Avoid clobbering exec_bfd while quitting.
4574 * Initial BFD (binary file diddling library) merger:
4575 coffread.c: Change AOUTHDR to struct exe_hdr.
4577 core.c: initialize initialized data at compile time.
4578 (core_file_command): Move from coredep.c, convert to bfd.
4579 (xfer_core_file): Convert to bfd.
4580 exec.c (exec_file_command): use bfd routines.
4582 mips-tdep.c: Remove exec_file_command and friends.
4585 * coredep.c: (fetch_core_registers) Convert core_file_command to
4586 fetch_core_registers.
4587 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
4589 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
4590 (my_bfd_read): More bogosity, which I don't think we call.
4591 (program_name): Remove this atrocity asap!
4593 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
4596 values.c: allocate_repeat_value was not clearing the
4597 optimized_out field.
4598 (value_static_field): minor stylistic fix (wrong macro was used).
4599 valops.c (value_struct_elt_for_address): didn't work for C++
4602 * signame.c (_initialize_signame): Initialize signal names once.
4604 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
4605 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
4606 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
4608 * remote-eb.c: Support user-settable baud rates on the serial port.
4610 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
4612 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
4614 * tconfig/sun3os4: Remove warning about native assembler,
4615 since it also occurs in the xconfig file.
4617 * findvar.c (registers): Allocate some slop after `registers'
4618 to prevent stray accesses from trashing the next variable.
4620 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
4621 on the sun-3, by changing the #ifdef from `sun3' (which is not
4622 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
4623 vars, which happened to follow `registers' in the executable.
4625 * readline/history.c (history_search): Heed gcc-2's advice
4626 and parenthesize && inside ||).
4628 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
4629 tm-29k.c: Insert FSF copyright headers.
4631 * remote-eb.c: Better comments.
4633 * Makefile.dist: Update to 3.91.6.
4634 * TODO: note PREPARE_TO_STORE problem.
4636 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
4638 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
4640 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
4642 * infrun.c (wait_for_inferior, at end): Don't set up
4643 prev_* if the inferior no longer exists.
4645 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
4646 CANNOT_EXECUTE_STACK.
4647 valops.c (call_function): Use it.
4649 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
4651 * inferior.h (PC_IN_CALL_DUMMY): New macro.
4652 infrun.c (wait_for_inferior, 2 places): Use it.
4654 * values.c (value_being_returned): Only use
4655 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
4657 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
4658 right thing for remote-eb.c.
4660 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
4661 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
4663 * blockframe.c: Put get_frame_saved_regs inside #if !defined
4664 (FRAME_FIND_SAVED_REGS).
4666 * findvar.c ({fetch,store}_registers): Check for
4667 REMOTE_{FETCH_STORE}_REGISTER macro.
4669 * findvar.c (get_saved_register): Add argument lval and
4670 change meaning of argument addr.
4671 findvar.c: Change calls to get_saved_register to reflect
4672 new calling convention.
4673 valops.c (value_assign): Use get_saved_register instead of
4674 find_saved_register.
4676 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4678 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
4679 an (uninitialized) pointer to one. Use "&" when passing it
4682 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4684 * coffread.c (getfilename): Use DGUX x_offset and x_name if
4687 * coffread.c (symbol_file_command): Put semicolon after
4689 Put safe_to_init_tdesc_context in #if defined (TDESC).
4690 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
4691 coffread.c: #include <sys/stat.h>.
4692 (read_coff_symtab): Typo: in_source_files -> in_source_file.
4693 Add missing ')' in check for "lc%" and friends. Remove
4695 Declare read_one_sym() at top of file.
4696 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
4697 MC68WRMAGIC can have the same value without causing a duplicate
4700 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
4702 * Allow a Makefile to be built without building the
4703 tm and xm file links that screw up builds in subdirectories.
4704 This is done with `config.gdb none', then you can do things
4705 like `make gdb.tar.Z'.
4706 * tconfig/none: Config file for no target system
4707 * xconfig/none: Config file for no host system
4708 * config.gdb: If no TM or XM files are called out by the
4709 host or target file, don't make links for them.
4711 * cplus-dem.c: Add documentation.
4713 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
4714 simple error, so the user's gdb doesn't crash due to some object
4715 file problem (e.g. somebody is rebuilding the file out from under
4718 * printcmd.c (print_address_symbolic): demangle the symbol.
4720 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
4721 Motorola copyrights in it. Make "make gdb.tar.Z" work.
4722 (alldeps.mak): sort and uniq all results from this; duplicates
4723 hose gdb.tar.Z link building. Remove RCS files from
4724 tconfig and xconfig. Add config files for sun386. Add
4725 a few odd files to OTHERS and HFILES.
4727 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
4729 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
4730 Roll version number to 3.91.5. Make lint work in bindir.
4732 * README: Document cross-debugging and new file structure.
4734 * blockframe.c: Lint. Include "value.h" to declare read_register.
4735 (find_pc_partial_function): remove duplicate line.
4737 * command.h: Lint. Declare error_no_arg and dont_repeat.
4739 * tm-news.h: Remove inadvertently duplicated stuff.
4741 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
4742 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
4744 * config.gdb: Allow `config.gdb host target' form. Clean
4745 up previous change that printed bogus messages when you just said
4748 * core.c: #include "command.h" for lint.
4751 * main.c: Remove some casts of enums. Lint.
4758 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
4760 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
4761 read it from memory. This will allow us to save ptrace calls
4762 eventually. Changed caller single_step too.
4764 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
4765 that we aren't going to use, saving many ptrace calls, especially
4766 when watchpointing or single stepping. Use some #define's for
4768 (store_inferior_registers): Ditto.
4769 (core_file_command): Use some #define's for constants.
4771 * tm-sparc.h: Add #define's for some register numbers, so we
4772 can eliminate the use of random constants in sparc-xdep.c.
4774 * stack.c (frame_command, print_frame_info, up_command,
4775 down_command) Remove frame_changed, since it
4776 causes a bug and doesn't seem to do anything useful. In some
4777 places it was used as a flag, in others as a stack level (?).
4779 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
4780 default is to use the portable (vprintf) version rather than the
4782 * xm-news.h (MISSING_VPRINTF): Add.
4784 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
4786 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
4788 * Remove stuff that forces -Bstatic linking of gdb, and warnings
4789 about linking debugged programs -Bstatic in the sun?os4 config
4790 files in tconfig and xconfig subdirectories.
4792 * main.c (main): Remove unreached exit(0) now that we exit
4795 * Create TODO file for online bug list. There are too many
4796 "little" bugs to keep track of on paper.
4798 * Change Projects file to refer to bug-gdb@cygnus.com
4799 rather than kingdon@ai.
4801 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
4803 * Makefile.dist (VERSION): 3.91.4 now.
4805 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
4806 (condense_misc_bunches): Add sanity check that misc_count is
4807 the same as the number of symbols in the bunch.
4809 * coffread.c: rename init_misc_bunches. Pass an argument
4810 to condense_misc_bunches (a zero).
4812 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
4813 every time we are called; don't rely on our caller to do it.
4814 (add_file): Remove call to init_misc_bunches.
4816 * mipsread.c: Only warn, don't error, if unknown symbol types.
4817 This keeps an old gdb from falling on its face if it sees newly
4818 extended symbol info. Rename init_misc_bunches.
4820 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
4822 * Merge in changes from Per Bothner for DECstations and other
4823 MIPS stuff. The rest is Bothner speaking:
4825 The next message is a merger of Alessando Forin's mips port with
4826 mine. I've tried to use my good if biased judgment to get
4827 the best of both. It *does* need testing.
4829 Some of the changes are general, *not* mips-specific.
4832 Didn't believe in little-endian bit order.
4833 There are still inconsistencies about whether flags
4834 like BITS_BIG_ENDIAN are integer (#if ...) or
4835 boolean (#ifdef ...). I tried to paper over them.
4837 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
4838 Moved some misc_function code that was common to
4839 {dbx,coff,mips}read.c to symtab.c.
4840 In the process, I think I cleaned things up a bit.
4841 At the same time, moved obsavestring and obconcat to symtab.c.
4844 Removed obsolete condense_addl_misc_bunches (use
4845 condense_misc_bunches(1) instead).
4848 Needed to include <sys/dir>, at least on DECstations.
4850 valops.c, mips-tdep.c, tm-mips.h:
4851 Added PUSH_ARGUMENTS macro to support funny argument-pushing
4852 conventions (when STACK_ALIGN is insufficient).
4853 Needed on mips, where doubles need 8-byte alignment,
4854 but ints only need 4.
4857 Removed cruft that was not being used.
4858 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
4861 Print $ before register-names (I think that makes things a little
4863 Never print two instructions, even if one delays.
4864 Removed hex-disassemble set_cmd. (This is not mips-specific,
4865 so I think the argument is whether it is generally worthwhile or not.
4866 I'm inclined to think not, given how easy it is to
4867 convert between radixes in gdb.)
4870 This is basically Alessando's code.
4871 It doesn't use obstacks; I changed it to use obstacks
4872 in a few minor places where using malloc causes a
4873 memory leak. (Probably, more places could/should be changed.)
4874 I added record_misc_function where it was missing.
4875 In symbol_file_command and add_file_command, I tried
4876 to make the code consistent with more recent versions.
4877 Minor sylistic changes in parse_procedure.
4878 Make a .gdbinfo. psuedo-symbol point back to the real
4879 procedure symbol (using the isym field).
4882 This is basically from my port, but with a lot of details
4883 and a number of routines merged in from Alessando's version.
4884 I basically used my code "raw" backtrace (use heuristics
4885 from the actual code, rather than symbol table info) - though
4886 the idea is Alessandro's. I feel my code is a little cleaner
4887 here, particularly in being a little more flexible, such as being
4888 able to handle gcc-produced code (which it now can).
4889 It also doesn't do frame caching (which is not useful
4890 more recent gdb versions).
4891 I also used my code for push_/pop_dummy, more or less.
4892 I tried to incorporate AF's code for testing sigtramp
4893 while backtracing; I probably got it wrong.
4894 Added mips_print_register, which tries to scrunch as much
4895 information as possible on a screen...
4896 Removed the skip-prologue set_cmd. As with hex-disassemble (see
4897 under mips-pinsn.c), I don't see anything mips-specific here,
4898 and I don't see it being all that useful anyway.
4901 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
4902 Use more register names (rather than hard-cases numbers).
4904 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
4906 * Hack up 3.90.11 changes:
4908 * Makefile.dist (depend): parameterize $(GCC).
4909 Add solib.c and solib.o.
4910 (readline): Fix vpath for both absolute or relative SRCDIR.
4912 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
4913 Also, let the part I didn't understand at least compile so
4914 I can test the rest. FIXME.
4916 * dbxread.c: Fix thinko using strcmp.
4917 (init_psymbol_list): declare static.
4918 (partial_symbol_file_open): Comment cleanups better, avoid
4919 cleaning up the string table since the caller will do that.
4920 Move the stat for mod time into symbol_file_command, temporarily.
4921 (There should be a mod time for each symbol file, eventually,
4922 to control its rereading. FIXME.)
4924 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
4925 SunOS, which gives error for shared libs otherwise. (From
4926 Schaefer, probably FIXME needs work for portability.)
4928 * solib.c: Move #include "param.h" to work.
4929 Lowercase all the Uppercase Letters In the Messages.
4930 (find_solib): Clean up inferior_so_name for debug printouts.
4931 Allow no argument, to mean all shared libraries.
4933 * symmisc.c: include param.h to get CLEAR_SOLIB.
4935 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
4937 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
4938 to 3.90.11. ChangeLog entries below are from this.
4940 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
4944 * Makefile.dist (HFILES): Add tm-sunos.h.
4946 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4950 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
4952 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
4954 * sparc-opcode.h Added single-operand version of rett.
4956 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4958 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
4959 Put parens around gcc_p in expansion.
4961 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
4963 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
4965 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4967 * Changes for Sun shared libraries:
4968 blockframe.c (find_pc_partial_function): If a non-text symbol
4969 is found, set *address = pc - FUNCTION_START_OFFSET.
4970 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
4971 Disable breakpoints instead of giving an error.
4972 source.c (select_source_symtab): Initialize cs_pst.
4973 symmisc.c: Call CLEAR_SOLIB if defined.
4974 symtab.h: Make text{low,high} CORE_ADDR not int.
4975 (psymtab): New field addr.
4977 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
4978 (record_misc_function): Give correct type for N_DATA symbols.
4979 (condense_misc_bunches): do "misc_function_count = j" regardless
4981 Take code which is shared between symbol_file_command and
4982 add_file_command and put it into partial_symbol_file_{open,read}.
4983 Split add_file_command into add_file_command and add_file.
4984 Make psymtab_to_symtab read in the string table if the file
4986 Two new parameters to read_dbx_symtab and start_psymtab.
4987 tm-sunos.h: New file.
4989 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4991 * infcmd.c: Change cont_command to continue_command and "cont"
4994 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4996 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
4998 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5000 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5001 size 1,2,4,8 rather than size < 8.
5003 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5004 as necessary, not just once.
5006 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5008 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5010 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5012 * tm-news.h: Add CALL_DUMMY_*.
5014 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5016 * config.gdb: In list_host, list_target, use ${i}, not $i.
5018 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5020 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5022 * sparc-opcode.h: Change all store floating-point state register
5023 instructions to have the right match & lose fields.
5025 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5027 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5029 config.gdb: If srcdir != ., create readline directory and
5030 copy a makefile into it.
5032 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5033 consistency with POSIX.
5035 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5036 when we exit its exp_valid_block.
5038 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5040 * Makefile.dist: Bump version to 3.91.3.
5042 * Clean up handling of breakpoint commands (somewhat).
5043 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5045 inferior.h: Add breakpoint_proceeded to inferior status struct
5046 and globals; save it and restore it.
5047 (clear_breakpoint_commands): Cleanup, remove old #define.
5049 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5050 (save_inferior_status, restore_inferior_status): handle it also.
5051 (proceed): Remove earlier code that set breakpoint_proceeded.
5052 It is now set only in clear_proceed_status.
5053 (clear_proceed_status): Cleanup, use bpstat_clear rather
5054 than clear_breakpoint_commands. No callers need the stop_bpstat
5055 between clear_proceed_status and proceed.
5057 infcmd.c: Add breakpoint_proceeded definition and comment.
5058 (cont_command, jump_command, signal_command): Move call to
5059 clear_proceed_status right next to call to proceed.
5061 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5062 caller's argument while running down the chain of breakpoints.
5063 Use new variable "breakpoint_proceeded" to determine when
5064 a command that it executes moves the inferior past the
5066 (bpstat_clear): Handle NULL argument.
5067 (bpstat_clear_actions): Avoid useless call to
5068 breakpoint_auto_delete.
5069 (delete_breakpoint): Clean up bpstat's that are pointing to
5070 the deleted breakpoint from the stop_bpstat chain.
5071 (breakpoint_auto_delete): Simplify.
5073 * Clean up handling of EOF, error on stdin, etc. This was
5074 prompted by a network problem that caused gdb to go into an
5075 infinite loop filling up its malloc'd memory.
5077 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5078 not clear_breakpoints_commands, which is now gone.
5079 (main): If command_loop returns (e.g. from EOF on stdin), do
5080 a quit_command (looping back to command_loop if quit_command
5081 doesn't really quit).
5082 (command_loop): check result from command_line_input and
5083 exit if it returns NULL, rather than passing the NULL to
5085 (gdb_readline): Free malloc'd result space before returning
5088 * utils.c (query): Handle C-d to mean "yes", just as if the
5089 input was not a terminal. Also avoid infinite loop if EOF
5090 occurs in mid-input-line before newline. This allows
5091 query to be used at EOF on stdin with reasonable results.
5093 * infrun.c (proceed): Set breakpoint_proceeded.
5095 * values.c (value_as_long): Avoid infinite recursion for enums.
5096 (_initialize_values): Fix typo in help msg (kingdon).
5098 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5099 RL_LIB for linking. This allows -lreadline for linking
5100 and nothing for dependencies, once readline is a real library.
5102 * config.gdb: Jim Kingdon: give useful error message if the
5103 host or target type is not recognized.
5105 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5106 it just defines it. Dumb, but deal with it.
5108 * Jim Kingdon suggests:
5109 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5111 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5113 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5115 * Clean up Bothner's changes.
5117 * blockframe.c (clear_pc_function_cache): New function.
5118 * blockframe.c: remake cache_pc_function_* static.
5119 * dbxread.c (symbol_file_command): remove references to
5120 cache_pc_function_* variables.
5121 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5122 * printcmd.c: Avoid kludging a global variable (addressprint)
5123 to avoid printing the address of a string twice. Instead,
5124 pass the format letter 's' down low enough that it can be seen
5125 to avoid this problem.
5126 (print_formatted): Pass format arg to value_print.
5127 (restore_addressprint): Remove function.
5128 (do_examine): Avoid hacking addressprint, cleanups and such.
5129 (print_frame_args): Add a comment to a Bothner change.
5130 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5131 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5132 to wipe out the values cached in blockframe.c.
5133 * symtab.c (find_method): Add comment saying how big you must
5134 allocate to be "big enough". Per being terse again.
5135 * valprint.c (val_print): Handle format letter "s" to print
5136 strings without addresses. Add comment to vtbl printing code
5137 which casts with wild abandon. Rearrange reference-printing
5139 @0xaddr: value (print w/addressprint)
5140 value (print w/~addressprint)
5141 @0xaddr (parameter lists w/addressprint)
5142 or nothing (parameter lists w/o addressprint)
5144 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5146 * Merge more changes from Per Bothner:
5148 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5149 annoying) that I tried to improve it. Here are my suggestions.
5151 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5154 Do automatic de-reference when taking the address of a reference.
5156 Don't deref_ref when printing parameter lists.
5158 More attempts at treating refernences properly.
5160 In val_print, if deref_ref==0, don't print dangling " = ".
5162 Add COERCE_REF macro, which de-references an REF.
5164 * Merge changes from Per Bothner:
5166 * Fixed (Sony news)-specific configuration problems.
5167 * Fixed other problems with using vanilla pcc and libc (enum problems;
5168 assumption that vsprintf exists).
5169 * Some major speed-ups (finc_pc_partial_function now caches a match;
5170 parsing avoids duplicate symbol_lookup calls).
5171 * Changed handling of baseclasses (no longer use baseclasses field
5172 of struct type, use the first n_baseclasses fields instead).
5173 * Various minor changes/fixes, most C++-related.
5176 Cache the most previous match from find_pc_partial_function.
5177 (Save both low and high ends of matching function's pc range.)
5178 This speeds up the loop of infrun.c:wait_for_inferior quite
5179 a bit, and makes step/next commands much zippier.
5181 Added an enum->int cast (otherwise, some compilers barf).
5183 No longer set baseclass offset to 0, since multiple
5184 inheritance now mostly works.
5185 Added a number of casts, to shut up compiler warnings
5186 (after stabs where made enums, not ints).
5187 When discarding a symbol table (in symbol_file_command),
5188 must clear the cache introduced in blockframe.c.
5189 Don't convert $vtbl_ptr_type to vtbl any more.
5190 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5191 Mask off sign bit emitted by g++ for virtual table offset.
5192 Set voffset to -1 (not 1) for static member functions.
5194 Changed parsing/lexing of names to avoid doing symbol lookup twice
5195 (once when lexing to determine symbol class, once for real).
5196 Now only call symbol_lookup once. Fields of 'this' win especially big.
5198 Subpress printing addr twice in the case of 'x/s addr'.
5200 lookup_basetype_type is no longer used.
5201 Add find_methods as recursive helper function to decode_line_1.
5202 This allows multiple inheritance to work.
5203 Also, once one or more matches has been found, do not look in
5204 base-classes. (Baseclass methods would be overridden, anyway.)
5206 Removed baseclasses array in struct type.
5207 Instead of using baseclasses[i], use fields[i-1].
5208 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5209 Changed sign convention of voffset (previous was inconsistent).
5211 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5213 Used to assume existence of vsprintf. Re-written to not need it
5214 if HAVE_VPRINTF is undefined.
5216 typecmp was too pessimistic. Made it less so.
5218 Don't print space after address.
5219 If vtable points to a misc symbol (with 0 offset), print it,
5220 since that indicates the actual class of the object.
5221 Changed ype_print_derivation_info to use new inheritance
5222 scheme (without baseclasses vector).
5224 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5225 Also, changes needed because TYPE_BASECLASSES were removed.
5227 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5229 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5232 If there is no path set, and the symbols don't indicate what directory
5233 a file was compiled in, look in the current directory. But either
5234 a path or a known compilation directory will prevent this.
5237 Three independent bug fixes:
5238 * Remove the #if 0 block that breaks some stuff.
5239 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5240 adapt gdb to either SunOS 4.0.* or 4.1.
5241 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5244 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5247 (type_print) Demangle the name being printed.
5248 (type_print_base) Handle botched demangling without coredump (tiemann).
5251 (check_stub_method): Document routine.
5252 (tiemann) fix bug for no-arg functions
5253 Avoid clobbering beyond end of malloc'd storage.
5254 Terminate the argument list properly.
5256 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5258 * Changes merged by John Gilmore:
5261 In breakpoint_1, use new print_address_symbolic instead
5262 of find_pc_partial_function. (This forces use of assembler-level
5263 addresses, and avoids misleading non-mangled source-level names.)
5265 Generalize ansi argument such that -1 means skip arglist totally.
5266 Removed global variable print_ansi_qualifiers (which made
5267 code non-reentrant), in favor of extra explicit arguments
5268 to internal routines.
5270 Add new helper function print_address_symbolic.
5271 Use find_pc_misc_function instead of find_pc_partial_function
5272 (since we want assembler-level symbols here).
5274 Print unknown function as just "f (...)", not "f (...) (...)".
5275 Use new fputs_demangled explicitly.
5277 Fixed a typing violation (problem: value.h cannot be imported
5278 without renaming many variable in this file).
5279 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5280 decode_line_1: Moved forward some never-reached code.
5281 Made decode_line_2 skip function prologues correctly.
5283 fputs_filtered should not demangle by default.
5284 Add new fputs_demangled to demangle on demand..
5286 Change value_struct_elt to use value_primitive_field (using recursive
5287 utility function search_struct_field). This allows foo.bar to work
5288 for multiple inheritance (so far only for data fields).
5289 Change check_field in the same way (recursive helper function
5290 to support multiple inheritance).
5291 (Note: there are more of these problems that I haven't fixed.
5292 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5293 value_of_this: 'this' symbol name is now just "this", note "$this".
5295 Don't print static members.
5296 Avoid printing "members of <type>" if there are none.
5297 Simplified type_print_derivation_info by merging duplicate code.
5298 Remove useless blank lines in type_print_base (ptype command).
5300 Added declaration of new routine value_primitive_field.
5302 Added value_primitive_field which is generalized version of
5303 value_field that can handle multiple inheritance (non-zero offsets etc).
5304 Re-implemented value_field to call value_primitive_field.
5306 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
5308 * infcmd.c -- insert else to avoid 'delete env' coredump when you
5309 delete the whole environment. Karl Berry reported the bug.
5310 * source.c - fix openp to avoid //'s in filenames, which
5311 trigger an Emacs bug causing it to not be able to find files
5312 when running gdb in a window.
5313 * dbxread.c - zap the #if 0 that botches the add-file code.
5314 It seems to work a lot better without all the code commented out.
5316 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
5318 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
5321 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
5323 * Makefile - added a ${CFLAGS} to a couple of entries,
5324 added remote-sa.sparc.c
5325 * added remote.sa-sparc.c, a modification of remote.c
5326 which conducts a dialog directly with the SparcStation prom.
5327 * breakpoint.c, infrun.c, sparcdep.c added
5328 remote_insert_breakpoint(), and remote_remove_breakpoint()
5329 to breakpoint.c instead of directly writing breakpoint instructions.
5330 * sparcdep.c on remote_debugging,there is no need
5331 to remove signle step breakpoint instructions.
5332 * main.c added "-epoch" flag and "int epoch_interface" to main.c
5334 * printcmd.c - epoch interface sends lisp expressions to open up
5335 epoch windows on inspection.
5336 * valprint.c - added arrayprint, and addressprint and made adding
5337 format controls easier
5338 * wait.h added a couple of undef's because we were getting
5339 complaints about WSTOPSIG and WTERMSIG begin redefined.
5342 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
5344 * symtab.c (decode_line_1): Add support for handling method stubs
5345 in the type information.
5347 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
5349 * values.c (baseclass_addr): Run loop from INDEX+1 to
5350 N_BASECLASSES; otherwise, we can still get into a loop.
5351 @@ This should be restructured to use a cleaner search strategy.
5353 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
5355 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
5356 abbreviation "Tt" for tags which have the same name as their
5359 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
5361 * symtab.c (list_symbols): add ability to set breakpoints on all
5362 the functions which match a particular regular expression.
5364 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
5366 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
5367 should print ANSI qualifiers (such as `const' and `volatile').
5368 All callers changed to call with ANSI == 1, except from
5369 `check_method_stub', which uses old-style syntax.
5371 * symseg.h (struct fn_field): Remove unneccessary `args' field.
5372 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
5374 * values.c (check_stub_method): New function.
5376 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
5378 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
5379 * valprint (type_print_base): Ditto.
5381 * symtab.c (gdb_mangle_typename): New function.
5383 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
5385 * breakpoint.c (catch_command): New function. Provides a
5386 mechanism to set breakpoints based on catch clauses.
5387 (disable_catch): Similar, but disables breakpoints on catch
5389 (delete_catch): Similar, but deleted breakpoints on catch clauses.
5391 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
5393 * blockframe.c (blockvector_for_pc): New function.
5394 * blockframe.c (block_for_pc): Changed to call
5395 `blockvector_for_pc' and get the block itself.
5397 * stack.c (catch_info): New function. Prints info about
5398 exceptions which can be caught in the current frame.
5399 * stack.c (print_frame_label_vars): New function. Similar to
5400 `print_frame_local_vars'.
5401 * stack.c (print_block_frame_labels): Prints out labels that are
5402 defined in this frame. These labels are exceptions that can be
5405 * dbxread.c: Updated to handle N_CATCH symtab types.
5407 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
5409 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
5410 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
5411 when printing the type.
5413 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
5415 * valprint.c (val_print): Use `baseclass_addr' to access the
5416 baseclasses pointed to via the derived class object at VALADDR.
5418 * values.c (baseclass_addr): New function. Casts derived pointers
5419 to baseclass pointers taking virtual baseclasses and multiple
5420 inheritance into account.
5422 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5426 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5428 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
5429 exp_valid_block field correctly.
5431 * infrun.c (wait_for_inferior): When checking "don't even think
5432 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
5433 also check step_resume_breakpoint.
5434 Insert breakpoints and continue (not step) if
5435 step_resume_break_address != NULL, even if another_trap.
5436 If trap_expected and we enter sigtramp, then set up a
5438 If trap_expected is set when we hit the step_resume_break,
5440 When calling resume and trap_expected says tell resume to step
5441 (2 places), also check step_resume_break_address.
5443 * infrun.c (wait_for_inferior): Don't set
5444 prev_{pc,sp,func_{start,name}} before calling wait ().
5445 Do set them after exiting loop.
5446 Move their declarations outside functions.
5447 (start_inferior): Initialize them.
5449 Thu May 3 00:15:11 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5451 * infrun.c (wait_for_inferior, after check for trap_expected > 1):
5452 Restore old code which distinguishes between trap_expected and
5453 running_in_shell, just make the latter take any non-TRAP signal,
5456 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
5458 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.
5459 xconfig/3b1 (CC,PINSN_CC): Define.
5461 * xconfig/altos, altos-dep.c: Rename altos-dep.c to altos-xdep.c.
5465 * breakpoint.c (bpstat_stop_status),
5466 infrun.c (wait_for_inferior) [SHIFT_INST_REGS]: New code.
5468 * param.h, tm-88k.h: Define ADDR_BITS_*.
5469 infcmd.c (jump_command, read_pc), infrun.c (wait_for_inferior),
5470 printcmd.c (do_one_display): Use them.
5472 * utils.c: Split #ifdef USG into a USG_UTILS and a QUEUE_MISSING.
5473 xm-88k.h: Define USG_UTILS.
5475 Wed May 2 00:05:33 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5477 * printcmd.c (printf_command) [__INT_VARARGS_H]: New code.
5478 (printf_command): Add from_tty parameter.
5480 * valprint.c (value_print): Check VALUE_OPTIMIZED_OUT flag.
