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

83 (read_enum_type): Recognize FALSE/TRUE enum as Modula-2 BOOLEAN.
84 (read_range_type): Rename MAX_OF_TYPE to MAX_OF_C_TYPE, etc.

86 * coffread.c (end_symtab): Use allocate_symtab.
87 (process_coff_symbol): #if 0'd for functions and params as above.
88 (read_enum_type): Recognize Modula-2 BOOLEAN.
89 * symtab.c (add_param_to_type): #if 0'd function to add a

162 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
164 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
165 entries are enclosed herein:
167 Mon Jun 3 17:05:45 EDT 1991
169 m2-exp.y Created. Tested outside of GDB for a few days. Proper
170 operators were added, C specific operators and tokens
171 removed. yylex() revamped to some extent. Still things
172 missing from the grammar, such as sets.
173 Tested for two weeks in GDB v3.5.
175 Tue Jun 11 17:23:48 EDT 1991
177 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
178 so they are built-in. Sort of a hack.
180 Fri Jun 14 12:53:51 EDT 1991
182 m2-exp.y Added range checking for numeric constants. Any numeric
183 constant is assumed to be of builtin type INTEGER unless:
184 (1) it is octal or hexadecimal, in which case it is a
185 CARDINAL; (2) it is too big to fit into an INTEGER, in
186 which case it is a CARDINAL.
187 eval.c Added simple range checking for +, -, and * on integers.
188 Doesn't work very well for *, since 6 * 1,000,000,000 =
189 1,705,032,704, which fails the simple test of result >=
190 first_operand, no matter in what order the operands are.
192 Tue Jun 18 14:11:30 EDT 1991
194 Broke the parser into parts, one containing the C grammar and the other
195 containing code to be shared by all of the grammars.
197 The following files no longer exist:
202 The following files were added:
204 c-exp.y (The C grammar)
205 m2-exp.y (The Modula-2 grammar)
206 parser-code.c (Code that is shared by the above grammar)
210 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
211 now necessary to use the Bison compiler compiler, since it
212 will generate function/variable prefixes other than yy.
214 Tue Jun 18 16:47:49 EDT 1991
216 symtab.[ch] Added the external variable working_lang, than holds the
217 value of the current working language.
218 Added the ennumerated type language_mode, with the values
219 language_auto and language_manual, the former meaning that
220 GDB sets working_lang as needed, and the latter meaning
221 that the value of working_lang is totally under user
223 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
224 REAL, BOOLEAN and CHAR. Also added the type codes
225 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
226 utils.c Added set_language_command and show_language_command to
227 implement the GDB support commands "set language" and
229 expression.h A number of identifiers were added to the type exp_opcode
230 to facilitate Modula-2 builtin functions, integer
231 division, and array indexing.
233 Wed Jun 19 13:25:58 EDT 1991
235 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
236 if the language specified by working_lang requires the use
237 of strict typing of expressions. Eventually, even this
238 will be able to be changed by the user.
239 Added the macro RANGE_CHECK, which evaluates to non-zero
240 if the language specified by working_lang requires the
241 checking of a value against the domain of its type.
242 Eventually, even this will be able to be changed by the
244 language.[ch] Predicates involving types (simple_type, ordered_type,
245 same_type, integral_type, numeric_type, character_type,
246 boolean_type, float_type) are added. These predicates are
247 based on the current value of working_lang, and are handy
250 Wed Jun 19 15:39:34 EDT 1991
252 eval.c Added the function type_array_rank which computes the rank
254 valarith.c Added the funtion value_bool, which when given a integer
255 value.h value (ie. struct value *) as an argument, it returns a
256 boolean value (ie. struct value *) true if that integer
257 is non-zero, and a boolean value false otherwise.
258 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
259 will print out properly.
261 Wed Jun 19 16:36:34 EDT 1991
263 valops.c Added the function value_capitalize, which returns it
264 value.h argument capitalized if its argument is a lowercase
265 letter, or the argument unchanged if its argument is not a
267 valarith.c Added the function range_check_p, which returns non-zero
268 value.h if its value argument is between the integral bounds upper
270 Added the function range_check_enum_p, which makes sure
271 that its value argument is a valid member of the domain of
273 Added the function range_check_range_p, which makes sure
274 its value argument lies between the upper and lower bounds
275 of its type argument, which must be a ranged type.
276 Added the function check_array_index, which range and type
277 checks an index of an array.
278 Added the function value_multi_subscript, which computes
279 array[idx1,idx2...idxN], given a value array and an array
280 of values representing indicies.
281 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
282 unpack_long to work with TYPE_CODE_BOOL and
285 Wed Jun 19 18:04:08 EDT 1991
287 symtab.c Stored pervasive types in a structure and make
288 lookup_pervasive_type() a lookup function that was based
289 on working_lang. If lookup_pervasive_type() returned
290 non-zero, then that value was returned (a fix, since
291 before it simply wouldn't return the pervasive type.)
292 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
293 non-zero if the language specified by working_lang means
294 "conversion" when it says "cast".
295 valops.c Added the function value_real_cast(), which performs a
296 value.h *cast*, not a *conversion*, which is what value_cast()
297 does when it can. In particular,
298 value_cast(<float_type>,4) = 4.0, while
299 value_real_cast(<float_type>,4) = some mess.
300 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
301 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
302 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
303 and MIN on integral types. *NOTE*: These are currently
304 hardcoded to work only if there are 8 bits per storage
306 eval.c Made logical functions call value_bool to return a
307 properly typed boolean value, based on working_lang.
309 Thu Jun 20 11:55:27 EDT 1991
311 valprint.c Types now print out in a Modula-2 fashion. This works for
312 the cases when the type is printed out step-by-step, that
313 is, it doesn't work when the name of a structured type
314 (which includes the keyword "struct", etc.) is simply
316 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
317 since type specifications in C and Modula-2 are very
318 different. The C printing of a type is very recursive,
319 whereas in Modula-2 it is generally very simple. C has
320 type prefixes and suffixes, which have no real analogue in
321 Modula-2. Maybe type_print() should call a language
322 specific type printer. This is also advantageous if we
323 compile GDB to exclude some of the languages. We'll just
324 leave those functions out.
326 Thu Jun 20 16:57:10 EDT 1991
328 dbxread.c When reading the complete symbol table in (via
329 psymtab_to_symtab()), the number and types of function
330 arguments are added to a function type. define_symbol()
331 calls add_param_to_type() to accomplish this.
332 Assumption: when we come across a function definition
333 (N_FUN symbol with an 'f' or 'F' in the name), its
334 arguments will appear before another function definition.
335 When a function is found, a pointer to its type is placed
336 in the global in_function_type. Changes that
337 add_param_to_type() makes are to this global.
338 valprint.c The type of a function now includes (for Modula-2) the
339 types of its parameters.
340 eval.c Type checking and a check for the proper number of
341 arguments is now done for function calls. Not sure of the
342 impact this has on C++ member function yet.
344 Thu Jun 20 19:58:48 EDT 1991
346 valprint.c Rewrote the type printer. Broke it into two language
347 specific parts, adding the functions type_print_m2() and
349 An unfortunate consequence is this: if you debugging a C
350 program in Modula-2 mode (why?), info types does not work
351 well with regular expressions, since the types are printed
352 out in Modula-2 terminology, but stored in C terminology.
353 language.[ch] Added the functions new_type_last(), type_keyword(), and
354 type_sep() to aid in the printing of typedefs.
355 symtab.c Made the printing of typedefs as language independent as
356 possible through calls to new_type_last(), type_keyword(),
359 Fri Jun 21 11:50:26 EDT 1991
361 dbxread.c Check all incoming ennumerated types. If it looks like
362 Modula-2's BOOLEAN type, then change the type_code of the
363 type to TYPE_CODE_BOOL so we can process it as a boolean
365 valprint.c Replaced some of the 0x%x with calls to sprintf and
366 hexformat() in val_print().
367 language.[ch] Added the function hex_to_string(), which converts its
368 integral argument to a hexadecimal number (format is
369 language based) and returns the result as a string.
371 Mon Jun 24 12:25:07 EDT 1991
373 valprint.c Some functions call type_print_1() directly, instead of
374 value.h using type_print(), so they can specify where (column) to
375 print things. Since type_print() takes care of language
376 dependence, that needs to be called first. Added a
377 parameter depth to type_print() (so it is now like
378 type_print_1). Changed type_print to type_print_at, and
379 made type_print a macro that passes a depth argument of
381 symmisc.c Changed all calls to type_print_1 to calls to
383 Makefile.dist Made it possible to build GDB for a specific set of
384 depend languages. Do this by passing a definition for the macro
385 LANGS to make. LANGS should be a string containing a
386 space-separated list of language names (ie. LANGS="c m2").
387 The default is to build all languages. Note that grammar
388 files must follow the naming convention of <lang>-exp.y.
389 gdb.lang This holds the current value of the LANGS macro. It is
390 examined every time make is called, and is updated if
392 eval.c Added #ifdef _LANG_<lang> to these files.
393 expread.c Still need to add them to dbxread.c and coffread.c.
401 Mon Jun 24 16:33:11 EDT 1991
403 language.[ch] Added the functions hexformat_pre() and
404 hex_to_string_pre(), which take a prefix argument to
405 include in the format string. Thus, hexformat_pre("08") will
406 return "0x08x" (if the working language is language_c).
407 Made hexformat() and hex_to_string() calls to the above
408 with "" as the prefix argument.
410 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
411 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
412 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
413 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
414 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
415 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
416 valprint.c, vax-pinsn.c
418 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
419 calls to hexformat() and hex_to_string(). Format strings without
420 the leading "0x" were ignored.
422 depend Updated to take the above into account.
425 Tue Jun 25 15:27:18 EDT 1991
427 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
428 and type_check_t to keep track of the current state of
429 range and type checking.
430 main.c Added the variables range_mode, range_check, type_mode,
431 and type_check to record the current state of range and
432 type checking. Added initialization code to main().
433 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
437 Tue Jun 25 17:57:08 EDT 1991
439 dbxread.c process_one_symbol() updates the variable (enum language)
440 source_lang based on the extension of the filename
441 contained in the N_SO sybmol that started this symtab.
442 When end_symtab() is called, the value of source_lang is
443 put into the language field.
444 stack.c select_frame() sets working_lang (and possibly type_check
445 and range_check) to the language field of the symtab
446 associated with the frame that is selected if working_mode
447 is language_auto. If working_mode is language_manual, a
448 warning is printed and working_lang is not set.
449 language.c Added the function set_type_range(), which sets the value of
450 type_check and range_check (if their modes call for
451 automatic setting) based on the current value of
452 working_lang. A non-zero argument will cause the current
453 settings to be output.
456 Wed Jun 26 14:51:40 EDT 1991
458 eval.c Added range checks on assignment.
459 m2-exp.y Added the grammar for sets to the language. Currently,
460 these do not do anything except print an error message.
462 Wed Jun 26 17:01:04 EDT 1991
464 m2-exp.y Added the ability for parse_number() to parse negative
465 numbers. A global flag is set upon encountering a unary
466 minus. This was done to make, for example, 1 parse as a
467 CARDINAL, and not as an integer, per Wirth's examples in
468 Programming in Modula-2 ed.4.
469 valprint.c Added support for "set radix 2" by then setting
470 output_format to 't'.
471 eval.c Implemented range checking on subrange types. Added calls
472 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
473 Implemented MIN and MAX for ennumerated types. The
474 minimum value of an ennumerated type is defined by Wirth
475 as the first identifier, and the maximum as the last.
476 m2-exp.y Made octal numbers ending with "B" be characters and those
477 ending with "C" be numbers, per Wirth's book. (p. 34)
479 Thu Jun 27 14:11:52 EDT 1991
481 stack.c select_frame() now only sets working_lang, it does not
482 notify the user. If working_mode is language_manual, then
483 a warning is issued once.
484 main.c At the end of each call to execute_command(), working_lang
485 is checked against the local static (enum language)
486 current. If they differ and working_mode is
487 language_auto, the new settings of language, type and
488 range checking are printed out.
489 stack.c Modified frame_info() to include the language of the
490 current frame in the output of "info frame".
491 language.[ch] Added the function language_str() which returns the name
492 of the current language.
494 Fri Jun 28 15:33:14 EDT 1991
496 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
497 the language. INCL and DECL currently cause an error,
498 since sets are not implemented yet. INC and DEC are
499 implemented as PREINCREMENT/PREDECREMENT with one
500 argument, and as ASSIGN_MODIFY with two arguments.
501 eval.c Added type checking to the above cases.
502 value.h Added not_lval_constant to the lval_type ennumerated type.
503 not_lval_constant means that the value is a constant
504 value; that is 3 or 'a' or TRUE, not as in a constant
505 identifier. This is used to help coerce numbers such as 3
506 to either signed or unsigned numbers.
507 valops.c Added the function value_coerce_constants() which coerces
508 constant integers as following: if one is a constant and
509 the other is not, the constant's type is set to the type
510 of the other argument. If both are constants and one is
511 signed, the other is converted to a signed constant.
513 Sat Jun 29 17:26:29 EDT 1991
515 valarith.c Added a better range checker. It now checks range
516 (successfully) on integral operations [+-] (signed and
517 unsigned) for any C sized type. Still does not work well
519 int_in_size() returns an integer that is coerced to fit into
520 specified number of bytes.
522 Mon Jul 1 13:04:14 EDT 1991
524 language.[ch] Added the function binop_result_type(), which returns the
525 builtin (struct type *) type that would be the result of a
526 binop on the two values V1 and V2.
528 Wed Jul 3 19:22:53 EDT 1991
530 source.c Extended source_info() to include the source language in
531 the output from "info source".
533 Fri Jul 5 13:48:52 EDT 1991
535 utils.c Moved the support functions for the GDB set/show commands
536 dealing with language into language.c.
537 language.c Added the function language_info(), which displays info
538 about the current working language, type and range check
539 settings. Called via the GDB command "info language".
540 Added an initialization routine _initialize_language(),
541 that sets defaults for the language, type and range
542 variables and sets up the new GDB commands.
543 main.c Language setup moved to language.c.
546 Mon Jul 8 10:10:22 EDT 1991
548 valarith.c Debugged the range checker for arithmetic. Still does not
549 work for multiplication very well.
551 Mon Jul 8 12:40:37 EDT 1991
553 language.[ch] Added the function value_true() which returns non-zero if
554 its argument represents a boolean true value.
555 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
556 check the truth of an expression.
558 Thu Jul 11 12:51:34 EDT 1991
560 language.[ch] Added the predicate structured_type(), which returns
561 non-zero if the argument is a structured type.
562 Added the predicate pointer_type(), which returns non-zero
563 if the argument is a pointer type.
564 eval.c Added the ability to do addition and substraction on
565 pointers and integers. This case simply bypasses the
568 Thu Jul 11 14:41:42 EDT 1991
571 Added the symbol N_DEFD (0x4a) which is a definition
572 module dependency that is used by the GNU Modula-2
573 compiler and the linker. It is not important to GDB,
574 except that [dbx|coff|mips]read.c should ignore these
577 Fri Jul 12 16:07:00 EDT 1991
579 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
580 0 in val_print(). Also added statements to the else part
581 to coerce type (argument to val_print) to a pointer type
582 if it is an "array of unspecified length".
583 valops.c Added the function value_m2_string(), which returns a
584 (value) value which is a constant string, whose type is
585 (ARRAY [0..n] OF CHAR). The length field of the type
586 structure is set to zero, so it will be interpreted as an
587 "array of unspecified length".
588 stack.c Moved the language/frame mismatch check to
589 main.c:execute_command().
590 main.c The working language is recorded each time
591 execute_command() is executed. If working lang has
592 changed during its execution, then the new
593 language/type/range info is printed out for the user. If
594 the working language does not match the language of the
595 frame, a warning is issued.
597 Sat Jul 13 16:16:39 EDT 1991
599 eval.c Moved all the type-checking stuff for operators to
600 language.[ch] language.c. This is so we can keep language-specific
601 stuff (like for what type operators are defined) in
603 language.[ch] Added the function binop_type_check(), which checks to see
604 if its two (value) arguments are type-compatible with its
605 opcode argument. The opcode should represent an operation
606 involving an operator. Also added the macro function
607 unop_type_check, which calls binop_type_check with a
608 NULL second argument.
609 expprint.c Added Modula-2 operators to the op_print_tab, so info
610 expression.h break works correctly. Also added "op_string", which
611 returns the string corresponding to the (enum exp_opcode)
612 opcode that is its argument.
615 Sat Jul 13 18:26:18 EDT 1991
617 coffread.c Added code to record the type of function arguments with
618 each paricular function. Code is very similar to that
620 dbxread.c Moved add_param_to_type() to symtab.c
621 symtab.[ch] Added function add_param_to_type() from dbxread.c
623 *** NOTE: The above additions have not been tested.
625 Mon Jul 15 12:50:47 EDT 1991
627 langauge.[ch] Added the functions type_error and range_error, which work
628 like error() except if the type/range mode is set to
629 *_mode_warn, then they do not do a return_to_top_level(),
630 but merely print a warning.
631 Also changed [set|show]_[type|range]_command() to support
632 the new "warn" feature.
634 Thu Jul 18 17:50:54 EDT 1991
636 mipsread.c Added code to record the type of function arguments with
637 each particular function. Code is very similar to that
640 *** NOTE: The above additions have not been tested.
642 Fri Jul 19 11:19:10 EDT 1991
644 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
645 UMIN_OF_SIZE, which when given a size of a numeric type,
646 return the maximum and minimum value it can hold. UMAX...
647 and UMIN... return the result for unsigned types.
648 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
649 struct types. They call above macros.
650 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
651 avoid a name conlict with the above.
652 c-exp.y Added range checking on numeric constants in
653 parse_number() for completeness.
654 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
655 return 0 if working_lang is not language_c.
657 Thu Aug 8 14:17:22 EDT 1991
661 breakpoint.c Documentation strings of some commands changed to
662 eliminate the references to the C language where
665 Tue Aug 13 15:48:03 EDT 1991
667 m2-exp.y Added qualified identifiers to the grammar. The semantics
668 are slightly different from those of the GDB operator ::
670 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
671 type_exp, where type_exp is any valid type expression.
673 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
674 printcmd.c Modified ptype_command() so it actually parses the input
675 (necessary for type expressions with scope qualifiers).
676 Added the function ptype_eval() which expects an
677 expression composed of one OP_TYPE element.
678 *.[ch] Replaced all occurences of parse_c_expression with
680 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
682 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
684 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
686 Small fixes from Peter Schauer:
688 * infrun.c (child_attach): Lint.
689 * solib.c (find_solib): Handle shared libs version 2.
691 Small fixes from David Wood:
693 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
697 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
698 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
700 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
701 chars_per_line is at maximum (user typed `set width 0'). Fix
702 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
704 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
706 * coredep.c: include ptrace.h where necessary.
707 * mipsread.c(parse_lines): fix unsigned char problem that was
708 messing up line numbers on SGI's and possibly other MIPS based
710 * infrun.c (child_create_inferior): use better test to check
711 return val from setpgrp().
712 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
713 for sgi/irix support.
715 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
717 * mipsread.c (parse_symbol): Put non-static procedures
720 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
722 Patch together `text_start' and `text_end' for 29K port.
724 * exec.c (exec_command): If NEED_TEXT_START_END, define the
725 variables and set them based on the exec file.
726 * am29k-tdep.c: declare text_start.
727 * valops.c (call_function_by_hand): declare text_end.
729 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
730 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
731 because machines that do this will also have to know to
732 set NEED_TEXT_START_END. Besides, it was a redundant way to
734 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
735 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
738 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
740 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
742 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
743 Pass MUNCH_DEFINE to munch whenever we run it.
744 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
745 format string; use 0x%x instead.
746 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
747 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
748 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
749 * inflow.c: Handle `short' process group IDs.
750 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
751 and check for ptrace errors.
752 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
753 (coff_symfile_init): Initialize text_bfd_scnum.
754 (read_coff_symtab): Use it to find the text [and absolute?] sections.
755 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
756 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
757 Merge target arm case with other "easy" cases. Add target
758 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
759 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
761 * minimon.h, remote-adapt.c, remote-mm.c: Add.
762 * munch: Cope with RT/PC putting fns in data segment.
763 Restore ability to override `nm' by specifying MUNCH_NM.
764 * xconfig/rtbsd, xconfig/ultra3: New host systems.
765 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
766 and remote-adapt. Remove encapsulated coff #define's (the
767 support should go in BFD, and gdb shouldn't know or care).
768 * tconfig/a29k-kern: Same, but for remote kernel debugging.
769 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
770 * tm-29k.h: Update BADMAG (though it should go away).
771 Allow the register definitions to be overridden in another
772 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
773 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
774 DUMMY_SAVE_GR96, for handling kernel calling conventions
775 that use GR64+ rather than GR96+.
776 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
777 remote debugging of Ultra3 kernel. Includes tm-29k.h and
778 overrides various things.
780 * remote-mm.c (mm_attach, mm_wait): Handle attach like
781 child_attach does, making a clean stop in the newly attached
785 * coffread.c: Make coffread independent of any particular
786 variant of COFF. Avoid #include-ing any particular one except
787 internalcoff.h. BFD now passes key values for symbol reading
788 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
789 and the symbol masks and shifts); use them.
790 Remove obsolete end_of_text_addr.
792 * exec.c: Remove unused include files.
794 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
796 * Makefile.in (documentation targets): Pass $(M4).
797 Bugfix from eggert@twinsun.com (Paul Eggert).
799 * stack.c (down_silently_command): Check for stack existence.
801 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
803 * Makefile.in (VERSION): Update to 4.0.3.
805 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
807 * core.c (core_file_command): Print frame at coredump with
808 its level number, by calling print_stack_frame.
809 * frame.h: Add selected_frame_level, print_stack_frame.
810 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
811 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
812 Change print_sel_frame and print_selected_frame callers to
815 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
816 * symfile.c (free_named_symtabs): Ditto.
817 * main.c (main): wrap_here needs an arg.
818 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
819 (solib_add): Avoid noise.
820 (solib_create_inferior_hook): Lint.
821 (sharedlibrary_command): Move dont_repeat to here.
822 * utils.c (error): Call wrap_here to force buffered output.
824 Small patches from Peter Schauer:
826 * coffread.c (start_symtab): Free any existing line_vector before
828 (read_coff_symtab): Ditto for type_vector.
830 * source.c (lines_to_list): New variable, replacing function.
831 (all uses): Use as variable.
832 (_initialize_source): Add 'set listsize' and 'show listsize'.
833 * utils.c (lines_to_list): Remove function.
834 * stack.c (print_frame_info): Use as variable.
835 * defs.h (lines_to_list): Remove declaration.
837 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
839 * breakpoint.c (insert_breakpoints): Restore warning about
840 the program might be running in another process, but only for
841 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
842 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
844 * utils.c (error): if error_pre_print is set, print the string
846 * main.c (main, print_gnu_advertisement, print_gdb_version):
847 Reformat legalese so it always prints, but acts as an "I'm here"
848 message while symbols are being read. If any errors occur,
849 print a few newlines to set off the message and start it at the
850 left margin. Remove mention of "help" command, and don't yak
851 about symbol reading.
852 (catch_errors): Error string is now printed first in case of
854 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
855 suggest the "help" command.
857 * Makefile.in (VERSION): Set to 4.0.2.
859 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
861 * .gdbinit: Remove useless "rr" command. Set complaints
862 to 1 for people debugging gdb.
864 * breakpoint.c, remote-vx.c: Reword strings printed by
865 catch_errors callers.
867 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
869 * WHATS.NEW: "history write -> history save". Doc "write on/off".
870 (Fix from kenc@viewlogic.com.)
872 Fix some infrastructure to be able to cope with host and target
873 machines with different sized basic types (ints, ptrs, etc).
874 (Idea from pierre@la.tce.com (Pierre Willard).)
876 * values.c (value_from_longest): Rename from value_from_long.
877 Handle pointer types as well as integers, so that targets with
878 different pointer sizes from the host can be accomodated.
879 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
880 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
881 uses of value_from_long to value_from_longest.
882 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
883 the correct pointer type to value_from_long{est}.
885 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
887 * remote-vx.c: Remove obsolete code for calling functions via
888 vxworks kludge interface (it referenced value_from_long).
890 * valops.c (value_string): Find malloc with lookup_misc_func, not
893 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
895 Make writing to files work properly. (Fixes to BFD are also needed.)
897 * core.c (core_open): Open file ourselves, read or r/w, depending on
898 write_files. Use bfd_fdopenr.
899 * gdbcore.h (write_files): New variable.
900 * exec.c (write_files): Define variable, add set&show for it.
901 (exec_file_command): Use write_files to open for read or r/write.
903 Make shared library reading happen automatically. These changes
904 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
906 * inferior.h (stop_soon_quietly): Add to exported variables.
907 * infrun.c (child_create_inferior): call solib hook, if defined.
908 (child_attach): call solib hook, if defined.
909 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
910 (find_solib): Use lookup_misc_func rather than hand-rolled.
911 (symbol_add_stub): New stub for catch_errors.
912 (solib_add): Avoid output if !from_tty. Catch errors rather
913 than just calling symbol_file_add and bombing.
914 (solib_create_inferior_hook): Interface with the target process
915 to let it read and alloc shared libs, then figure out what it did.
917 * core.c (validate_files): Fix typo, soften warning.
918 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
920 * utils.c (fputs_demangled): Avoid duplicate printing if
921 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
923 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
924 (Fix from pierre@la.tce.com (Pierre Willard).)
926 * main.c (catch_errors): Change argument to a char * from an int,
927 since a char * can point to a struct full of glop, but an int
928 is not guaranteed to be able to hold a pointer.
929 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
930 breakpoint_re_set_one, breakpoint_re_set): Adapt.
931 * core.c (core_open, solib_add_stub): Adapt.
932 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
934 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
936 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
937 by adding .NOEXPORT target.
939 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
943 * Makefile.in (VERSION): Roll to 4.0.
944 (gdb.tar.Z): Make refcard.ps as well, for shipment.
946 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
948 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
951 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
954 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
956 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
957 reflect above name change
959 * WHATS.NEW: correct pointer to refcard.
961 * doc/gdb.texinfo: update New Features, Installing
963 * doc/gdbint.texinfo: add short description of configure +template
965 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
967 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
969 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
971 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
972 tar file, add dependencies for referenced doc files.
974 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
976 * coffread.c, symfile.c, stack.c: saberized.
978 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
980 * doc/refcard.tex: permuted Essential Commands sec
982 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
984 set/show symbol-reloading
985 default set complaints 0
987 RET-repeat disabled after prompted long displays
988 processID (attach) interpretation of 2nd GDB cmdline arg
990 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
992 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
993 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
994 breakpoint.c, main.c: lint.
996 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
998 Install new configuration scheme for GDB and friends.
1000 * config.sub: Translate ordinary names to three-part names.
1001 * configure: Use three-part names internally.
1002 * configure.in: Translate three-part names to filenames.
1004 * README, WHATS.NEW: Update for gdb-4.0.
1005 * Makefile.in: Roll VERSION to 3.99.
1007 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1009 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1010 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1011 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1012 to single structures rather than arrays; when passing
1013 their address, use &. This avoids trouble with bdead compilers.
1014 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1015 instead. This avoids portability headaches.
1016 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1018 * source.c (open_source_file): Avoid ANSI const bdeath by
1019 skipping declaration and then casting result value.
1020 * tm-hp300bsd.h: Clarify comment.
1021 * utils.c (strstr): Result is const char *; ANSI bdeath.
1022 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1023 since system include file defines it differently from "defs.h",
1024 though the two are equivalent for our purposes.
1025 * tconfig/hp300bsd: Add m68k-tdep.o.
1027 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1029 * tconfig/sun*4: Remove warnings about system assembler.
1031 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1033 * mcheck.c: Avoid warning about undeclared abort fn.
1034 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1035 it causes recursive calls to error() when used in cleanups.
1036 To do so requires that we make it a function, so we do.
1037 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1038 * utils.c (do_cleanups): Remove the current cleanup from the
1039 chain *before* calling it, in case error() is called from it.
1040 The result won't be pretty, but won't be an infinite loop either.
1042 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1044 * dbxread.c (read_struct_type): Grok anon structs for C++.
1045 (vb_name, vptr_name): Null terminate these strings.
1047 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1049 Minor bug fixes from BSD Net2 gdb:
1051 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1052 returns 0, there is no previous frame.
1053 * breakpoint.c (commands_command): If !from_tty, don't call
1054 input_from_terminal_p().
1055 * dbxread.c (record_misc_function): Speed up slightly.
1056 (compare_psymbols): Ditto.
1057 * infcmd.c (do_registers_info): Take a second argument to
1058 determine whether to print float registers. "info registers"
1059 does not do so anymore. "info all-registers" does, now.
1060 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1062 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1063 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1067 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1068 executing_breakpoint_commands if we are interrupted by error.
1069 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1070 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1071 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1072 catch_errors() so we can setup the frame regardless of whether
1073 the shared libs work.
1074 * ieee-float.c (double_to_ieee_extended): Get exponent from
1075 right place in little-endian systems. From John Carey.
1077 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1079 * main.c: Remove unused terminating_signals and catch_termination().
1080 (long_options): Terminate with a zero element.
1081 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1082 (gdb_readline): Make call-compatible with readline.
1083 (init_signals): Improve comments re vfork vs. signal.
1085 * utils.c (prompt_for_continue): Use new gdb_readline().
1086 If we prompt for continuation, we don't let CR repeat the previous
1087 command, once we get back to a prompt. It's too easy to keep
1088 hitting CR, expecting "--more--" prompts, and have some long
1089 command start repeating on you.
1091 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1093 * blockframe.c (frameless_look_for_prologue): Speed up by
1094 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1095 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1096 Define two variants, one faster.
1097 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1098 and return zero, rather than giving an error.
1099 (setup_arbitrary_frame): Initialize the PC in the new frame.
1100 (skip_prologue): Add a second arg saying whether we're just
1101 checking for a frameless function or not.
1103 * core.c (core_open, core_close, core_xfer_memory): Move
1104 section table pointers and bfd* into the target_ops.
1105 (core_open): Allow errors in shared lib reading, etc.
1106 (core_files_info): Describe shared library sections.
1108 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1109 exec_files_info, set_section_command): Move section table
1110 pointers and bfd* into the target_ops.
1111 (add_to_section_table): Add BFD to section table.
1113 * target.c (target_xfer_memory, target_info): Pass target to
1114 xfer_memory and target_info functions.
1117 * gdbcore.h: Move struct section_table.
1118 * target.h: New home of struct section_table.
1120 * solib.c (solib_add): New argument is the target_ops whose
1121 section list is to be added to, if any. Reallocate the
1122 sections in that target to add any that come from shared libs.
1123 (throughout) so_sections renamed to sections.
1124 (solib_xfer_memory): Deleted.
1125 * tm-sunos.h (SOLIB_ADD): Add target argument.
1126 (SOLIB_XFER_MEMORY): Delete.
1128 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1129 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1130 from target_ops. It's the same on all targets. Add two section
1131 pointers to target_ops.
1133 * stack.c (find_relative_frame): Dump ancient algorithm for
1134 "down", just use handy "next" pointers.
1135 (frame_command): Don't error if there is no stack; let user
1138 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1139 modifies static state in the parent process; new_tty itself
1140 runs in the child and modifies the child's file descriptors
1141 to match the saved static state.
1142 * infrun.c (child_create_inferior): Call new_tty_prefork,
1145 * infptrace.c (child_xfer_memory): Add ignored target arg.
1146 * remote-eb.c (eb_xfer_inferior_memory): ''
1147 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1148 * remote-vx.c (vx_xfer_memory): ''
1149 * remote.c (remote_xfer_memory): ''. Rename from
1150 remote_xfer_inferior_memory.
1152 * main.c (main): Only try to attach "corefile" argument if
1153 it starts with a digit.
1155 * symfile.c (symbol_reloading): New "set/show" variable.
1156 (symbol_file_add): Shorten message about symbol reading.
1157 (add_symbol_file_command): Merge with add_syms_addr_command,
1158 since this should work on all targets now.
1159 (stop_whining): Default to zero, to shut up complaints
1160 about bad symbol tables on many systems.
1161 (free_named_symtabs): Just exit unless symbol_reloading.
1163 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1164 and add comment explaining shared library screw.
1166 * source.c: #if defined => #ifdef.
1168 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1170 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1172 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1174 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1175 (doc/Makefile knows how to make one for local config)
1177 * Makefile.in: use doc/Makefile for doc targets
1179 * doc/Makefile: GDB documentation now has its own Makefile
1180 doc/refcard.tex: renamed from "gdbrc.tex"
1181 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1182 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1185 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1187 * values.c (baseclass_addr): When reading target memory, use the
1188 length of the basetype, not the upper type. We've only malloc'd
1189 enough space for the basetype, leading to errors in free().
1191 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1192 ends up as a function specially, since we know the actual type of
1193 the pointed-to address. This (somewhat) fixes display of
1194 expressions that include misc_function_vector names. Try `cond 1
1195 !strcmp("a","b")' then `i b'.
1197 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1198 The child can be proceeded from inside wait_for_inferior in
1199 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1200 getting skipped in that case.
1202 * expprint.c (print_subexp): Use filtered output, since the
1203 subroutines we call use it, otherwise the output is horribly
1204 mangled, since output of wrappable stuff comes out late.
1206 * Makefile.in: Bump VERSION to 3.98.1
1208 * infrun.c (child_create_process): Use execlp to find the
1209 shell to exec our target program. This requires some fiddling
1210 with `environ' since there is no execlpe().
1212 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1214 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1215 Minor rearrangement of refcard permits two new make targets--
1216 gdbrc.dvi DVI output for refcard, using CM fonts
1217 gdbrc.ps PostScript refcard, using PS fonts
1219 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1223 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1224 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1226 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1228 * doc/gdb.texinfo: last changes for release.
1229 Minor typo and formatting fixes; incorporated most fixes remaining from
1230 filed mail commenting on earlier drafts.
1232 Added warnings: pipes don't work in run command;
1233 conditions are converse of assertions;
1234 step over fn without debug info goes to next fn;
1235 vars may have "wrong" values near fn entrance, exit
1237 Added example from Kingston on printing repeated nonadjacent values
1239 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1240 shell mode for signals
1242 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1243 doesn't sound so much like its parent "Stopping and Continuing"; also
1244 moved entries on continue to top of section, so they don't get lost.
1246 Improved installation directions in appendix, added manual formatting
1249 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1251 * configure.in: Remove xm.h and tm.h even if we aren't linking
1252 new ones, so "./configure sun4; ./configure none" does the right
1253 thing. Assume that alldeps.mak and depend are already built in
1254 srcdir, and avoid running "make" (particularly "make depend",
1255 which involves "gcc") from inside configure. Build Makefile
1256 directly rather than building Makefile.conf first.
1257 * configure: Regenerate with above changes.
1258 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1259 to 3.98. Revise gdb.tar.Z procedure to produce a file
1260 called gdb-$(VERSION).tar.Z but which unpacks into a
1261 directory called "gdb". Move non-source files out of
1262 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1263 (depend): Don't try to do "gcc expread.y".
1264 (expread.o): Update dependencies by hand.
1266 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1269 Fixed a variety of small typos that prevented info from formatting
1270 cleanly; altered too-long heading for GPL Appendix, as discussed
1271 w/RMS; Changed date on cover to July 91.
1273 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1276 (1) Applied some fixes due to comments from Larry Breed (easier ones
1277 through chapsec 5.2)
1278 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1279 it's broken in latest texinfo
1280 (3) Introduced *some* use of [] for optional arguments, where
1281 explanation is not simpler by listing cmd w arg and cmd w/out arg
1282 separately. Still not using @deffn.
1283 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1284 couple of headings are too long. Need patches to texinfo or revision
1287 * Partial update to README (which still needs work for this
1288 release!): (1) use of configure corrected for new script,
1289 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1291 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1293 * symtab.c (lookup_symbol): Don't complain right off about
1294 no debug symbols; use the misc function vector first.
1295 (list_symbols): Use misc function vector to find symbols
1296 that don't have debug info, and print them.
1297 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1298 PC range doesn't match symtab PC range, as it does on the
1299 MIPS because our symtab reading isn't perfect.
1301 * dbxread.c (dbx_symfile_read): Make warning about
1302 "no debug symbols" slightly nicer.
1304 * source.c (select_source_symtab): If "main" symbol exists,
1305 but decode_line_spec can't find line info, don't just return
1306 a zero; try other source symtabs or give an error.
1308 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1309 their low addresses first, then rip through fixing high addrs.
1311 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1312 <runene@ifi.uio.no>.
1313 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1315 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1317 * Minor, mostly mechanical, cleanup of doc subdir for clean
1318 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1319 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1321 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
1323 Mostly MIPS and general symbol-reading fixups.
1325 * doc/gdbint.texinfo: Add documentation on symbol-reading
1328 * mipsread.c: Remove kludges around #include "ecoff.h".
1329 Remove redefinitions of a_magic, etc, no longer used.
1330 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
1331 Fix global overview comments to match symfile.c protocol.
1332 (mipscoff_new_init): Eliminate cur_hdr if we have one.
1333 (mipscoff_symfile_read): Eliminate unused code. Avoid
1334 sorting all the symtabs, when all we have read here is psymtabs.
1335 The symtabs are sorted as they are created anyway. Tell
1336 condense_misc_bunches whether we're mainline.
1337 (psymtab_to_symtab_1): Pass filename when recursing, to make
1338 stack trace more informative.
1339 (parse_partial_symbols): Assume cur_hdr as argument.
1340 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
1341 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
1342 the TYPE_NAME of char *, since that's done in symfile.c.
1343 (free_numargs, parse_symbol, add_symbol, add_block,
1344 shrink_linetable): Declare these fns void.
1345 (upgrade_type): Convert tree of if's to switch. Clean up
1346 bogus "off == 0" handling with a complaint. Avoid setting
1347 field bitpos and bitsize of array with lower and upper bounds.
1348 Check specified bitsize of elements against their actual type's
1349 bitsize, and complain if different. Complain about unknown
1351 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
1352 (psymtab_to_symtab_1): Print names of subsidiary files that
1353 are being read in. FIXME, we read far too many files. This code
1354 is not the problem, the problem is in parse_fdr where the psymtabs
1356 (cross_ref): Result should indicate that we used one aux entry
1357 normally, or two if we encountered a "next" entry. This used
1358 to leave the caller pointing at the wrong aux entry.
1359 (add_symbol): If overflowed cur_block, reallocate it larger,
1360 chase all pointers to it, and complain(), rather than clobber memory.
1361 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
1362 (new_field): Only allocate one field initially, not two.
1363 Pull ++ out of macro argument. Simplify.
1364 (_initialize_mipsread): Avoid initialization of importd
1365 global_psymbols and static_psymbols.
1367 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
1368 to properly set pst->symtab; avoid searching for it.
1369 (symfile_fns): Improve comments, add a FIXME.
1370 * dbxread.c: Update comments to reflect symfile protocol.
1371 (read_ofile_symtab, end_symtab): Return the symtab.
1372 (psymtab_to_symtab_1): Set pst->symtab.
1374 * coffread.c (coff_symfile_read): tell condense_misc_bunches
1375 whether we're mainline.
1377 * symfile.h (sym_fns): Remove unused sym_discard member.
1378 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
1380 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
1381 the environment variable is not.
1382 * infcmd.c (finish_command): Use filtered printfs.
1383 * cplus-dem.c: Add struct tags to a few unnamed structs.
1384 * valops.c (value_coerce_array): Improve comments.
1385 * valprint.c (type_print_varspec_suffix): Print array size only
1386 if greater than zero.
1387 * m88k-tdep.c: Shift some lines left by one space, that had
1388 apparently been trashed at some point.
1389 * TODO: More things to do, a few got done.
1391 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1393 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
1394 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
1396 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
1397 * expread.y, findvar.c, symmisc.c: Ditto.
1398 * printcmd.c (address_info): Update printed forms of LOC_
1399 symbols. Elim LOC_EXTERNAL.
1400 (print_frame_args): Keep track of param stack offsets before
1401 re-looking up to find the local register param is kept in.
1403 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
1404 Further integration of mipsread into gdb. Eliminate unused
1405 routines, duplicate declarations. Handle static symbols in
1406 psymtabs as well as external symbols. When reading symtabs,
1407 insert symbols into the correct block (global, static, or a local
1409 (read_mips_symtab, parse_partial_symbols): Don't pass useless
1411 (mipscoff_symfile_read): Don't call select_source_symtab.
1412 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
1413 rather than SYMBOL_VALUE.
1414 (parse_external): Comment clobbering of top_stack.
1415 (parse_partial_symbols): Update comments. Allocate and parse
1416 static symbols as well as external symbols. FIXME, enum values
1417 are not handled in this pass, but should be. Inline new_psymbol.
1418 Use SYMBOL_VALUE_ADDRESS.
1419 (psymtab_to_symtab_1): Read symbols into global static block
1420 by default (until enter some function's local block context).
1421 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
1422 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
1424 * source.c (select_source_symtab): Select a source symtab
1425 from either the symtabs or, failing that, the psymtabs.
1426 (list_command): Update error message.
1427 (forward_search_command, reverse_search_command): Use getc, not
1428 fgetc, for speed. FIXME, add comment about buffers that die if
1429 overrun by long line.
1431 * values.c (unpack_field_as_long, modify_field): Avoid shifting
1432 by an entire word, which is not portable, if we have a 32-bit
1433 field. (Code in dbxread.c already turns such bitfields, if
1434 aligned, into ordinary ints, but fixing this will help for other
1435 symbol formats and for future changes.)
1436 * core.c (core_open): Handle ANSI const brain death.
1437 * utils.c (vprintf): Fix varargs typo.
1439 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1441 * findvar.c (find_var_value): Handle &function better.
1442 * TODO: Document work needed on &fn and &array.
1443 * printcmd.c (print_address_symbolic): New arg is the prefix
1444 to print if a name is printed.
1445 (print_address_demangle): Honor "set print address" now.
1446 Use new arg above to improve spacing of output.
1447 * valprint.c (val_print): When printing function pointers,
1448 print symbolic form too.
1449 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
1451 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1453 * core.c (memory_error): Reword error msg to mislead less.
1455 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
1457 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
1458 parse_partial_symbols): Use newer BFD internals (external_filehdr
1459 and external_aouthdr), byte-swap the fields that we care about
1460 before using them, and make the file header data local to
1461 read_the_mips_symtab rather than global.
1463 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
1465 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
1466 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
1468 * main.c (command_line_input): Flush stdout and stderr
1469 before every call to readline. This reportedly fixes a bug
1470 that comes up in Sys V running emacs-gdb and/or xxgdb,
1471 when stdin/out are pipes or sockets.
1473 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1475 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
1476 Avoid declaring Makefile dependencies, because GNU Make stupidly
1477 tries to update it if we do.
1479 * coffread.c: Revise for minor changes to bfd internal coff
1482 * configure: If -template= is given a relative path, make it
1483 absolute before recurring in subdirectories.
1485 * configure, configure.in, Makefile.in: Install "configure" script
1486 as replacement for config.gdb.
1487 * config.gdb, Makefile.dist, Makefile.sdir: Remove
1488 * README: Update for configure, mostly. FIXME.
1490 * Add dec3100 as equivalent to littlemips. Indicate in all host &
1491 target config files that they are for the host. When the lines
1492 get copied into the Makefile, this makes it more obvious what's
1495 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1497 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
1498 tabs, which end up in the disassembler output inadvertently.
1500 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1502 Make it compile cleanly in an ANSI GCC2 environment.
1504 * blockframe.c: <stdio.h>
1505 * cplus-dem.c: free takes a void *, ifdef __STDC__
1506 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
1508 * defs.h (alloca): Avoid doing anything if alloca already def'd.
1509 * stddef.h, stdlib.h: Remove these files.
1510 * symtab.c: Avoid declaring qsort, close.
1511 * symfile.c: Avoid declaring close.
1512 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
1513 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
1515 Assorted other changes.
1516 * dbxread.c: include "libaout.h", not "liba.out.h".
1517 * printcmd.c (print_frame_args): Set recurse properly for
1518 indentation of struct and array parameters.
1519 * valops.c (value_cast): Allow cast to void.
1520 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
1521 single_step() in a target-independent fashion.
1522 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
1523 set up to be ready to continue. This makes us target independent.
1524 * infptrace.c (child_resume): Remove call to single_step; now
1525 can single step a SPARC target of any kind.
1527 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1529 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
1530 docn into separate sections---basically chapters, plus two loose
1531 pieces that can be configured to go in different places. This
1532 allows GNU m4 to preprocess the manual without coredumping.
1534 * Makefile.dist: tell TeX where to find texinfo.
1536 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1538 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
1539 the new target "rdl-apps.texinfo" which captures the Makefile
1540 variable that records where to find the Readline libraries.
1542 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
1544 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
1545 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
1546 * defs.h (const, volatile): Only define if not already defined.
1547 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
1549 * README: Update for release 3.95.
1550 * config.gdb: Don't create readline dir in subdir builds.
1551 * main.c: Include with "..." form for non-system include files,
1552 so "gcc -MM" for "make depend" works.
1553 Include readline files with "...h" rather than <readline/...h>.
1554 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
1556 * coffread.c: Undo minor damage done by Rich Pixley. Use
1557 different internal and external representations of COFF
1558 data structures. Use new BFD routines for swapping them in and
1560 * symfile.c (free_named_symtabs): Avoid freeing file names that
1561 are null or empty. Old i960 tools seem to produce files that
1562 claim to have empty names, causing each successive file read
1563 to blow away the previous one.
1564 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
1565 Move deferred_stores to top of file, but don't separate its
1566 #define's from its variable. Add commentary.
1567 * Makefile.dist: Fix Rich damage; undo "configure" changes in
1568 favor of keeping the (working) config.gdb. Move readline
1571 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
1573 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
1575 * infptrace.c (fetch_registers): no result, since now void.
1576 * tconfig/news: target depends on m68k-tdep too.
1578 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1580 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
1583 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
1584 applied various small fixes due to or inspired by RMS comments
1586 * doc/gdb.texinfo: finished using all RMS comments, save those for
1587 appendices on readline and cmd history (which are in other source
1590 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1592 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
1593 chapter 9; (2) documented 'break' command's menu mode for
1594 overloaded names, in response to hgs problem report C++ p-31
1596 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1598 * doc/gdb.texinfo: (1) better introductory example; (2) more
1599 consistent use of @code, @samp, @file, @kbd throughout; small
1600 cleanups to first three nodes; (3) new "Contributors" node;
1601 (4) Appendix, Renamed Commands; (5) divert specialized startup
1602 instructions to "Targets" chapter for generic manuals, while
1603 leaving them up front for manuals specific to specialized
1604 environments; (6) apply fixes from RMS comments through chapter 4.
1606 * pretex.m4: modify explanatory text slightly (and redefine
1607 "regexp") to keep GNU m4 from complaining. (It still crashes
1608 later, but one step at a time...)
1610 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
1612 * readline/readline.c (update_line): Avoid dereferencing a pointer
1613 before comparing it to its bounds. Saber caught this.
1614 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
1615 and only set PC if tgetstr returned non-null. Saber caught this.
1617 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1619 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
1620 stuff for config manual) here where it counts; updated
1621 to use new subdir structure (gdb/doc/).
1623 * Makefile: generated from above via
1627 * gdbint.texinfo: added instructions on generating gdb.info* files
1628 locally for release. These are ordinary info
1629 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
1630 Makefile)---but due to use of texinfo 2, can't count on makeinfo
1631 to generate these, so we distribute them already formatted.
1633 * gdb.texinfo: included full Info node and menu crud (as generated
1634 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
1636 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
1637 put in comments-for-future gdb.info target (one day makeinfo will
1640 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1642 * gdb.texinfo: Updated to include new or old undocumented
1643 commands, at least the following (perhaps some others I forgot to
1644 record): info f, info float, info path, info program, info s, info
1645 set, info source, info terminal, info types, info user, set/show
1647 Also covered all recent GDB command renames for v4.
1649 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1651 * mipsread.c: Rather than keeping count of how many symtabs
1652 and psymtabs we have, for sorting purposes, count them when
1653 we need to sort. This fixes bug in rereading of symbol tables.
1655 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1657 * infcmd.c: renamed "info path" to "show paths"

1672 symtab.h, target.c, target.h: Lint.
1673 * core.c: setup and select frame after reading shared libs,
1674 else reading shared libs will clobber them. Lint.
1675 * utils.c (error): Force out any buffered wrap text.
1677 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1679 * remote.c: Remove decls of memory_insert_breakpoint
1680 and memory_remove_breakpoint, no longer used. (Suggestion of
1683 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
1684 to make it easier to interface to "configure"'d libraries.
1686 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
1688 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
1689 aliases for set/show print.

1819 Remove from_tty arg to mod_path.
1820 Put symfile_bfd in {coff,dbx}read.c not symfile.h.

2200 (add_target): Call add_cmd and mess with targetlist->doc.
2201 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
2202 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.

2232 command is add-symbols.
2233 * target.c (dummy_target): Permit add_syms_addr_command.
2235 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2237 Permit symbols to be superseded when new symbol files have
2238 been read in, particularly for VxWorks.
2240 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
2241 to the main file, as well as to include files. Also, put global
2242 functions into the global psymtab, to make "i fun" work.
2243 (end_psymtab): Free named symtabs and psymtabs for a file, once a
2244 new psymtab for it has been read.
2245 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
2246 a file, once a new symtab has been read for it.
2247 * mipsread.c: FIXME. We need to do the same for MIPS, but it
2248 looks harder to determine the top-level block before it's been
2249 queued to the psymtab list.
2251 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
2252 If we have wiped out any old symbol tables, clean up at end of
2254 (symbol_file_command): Don't reference symfile_fns if it's zero.
2256 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
2257 defines for the blocks of a blockvector that contain global and
2258 file-static symbols and the first of the smaller scope contours.
2259 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
2260 decode_line_1, make_symbol_completion_list): Use the above.
2261 * coffread.c (end_symtab, patch_opaque_types): Ditto.
2262 * dbxread.c (end_symtab): Ditto.
2263 * expread.y (block): Ditto.
2264 * mipsread.c (throughout): Ditto.
2265 * symmisc.c (free_named_symtabs): Ditto.
2267 * symtab.c (list_symbols): Process the first symbol of the
2268 static psymbols list.
2269 (types_info): Restore this function from its untimely #if 0.
2270 It's not perfect, but it is better than nothing.
2271 (_initialize_symtab): Restore "info types".
2273 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2275 * m68k-stub.c: Remote stub for 680x0's, created from
2276 rem-m68k.shar (which is removed).
2277 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
2278 Remove RCS log stuff now that we use CVS and it blows our diffs.
2280 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2282 * symmisc.c (free_named_symtab): Make it work, in its current
2283 kludgy fashion. Change result to indicate if we blew away bkpts.
2284 * dbxread.c (end_symtab): Accumulate result from
2285 free_named_symtab and print warning if we blew user's state.
2286 * symfile.h: free_named_symtab now returns an int.
2288 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
2290 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
2291 is the first symbol read, even if not mainline.
2292 (dbx_psymtab_to_symtab): symfile might be zero, cope.
2293 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
2294 (set_section_command): New command ("section xxx yyy" -- should
2295 be renamed to "set section xxx yyy" FIXME) which sets the
2296 base address of a section of the exec file, overriding the
2297 virtual address that BFD reports.
2299 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2301 * exec.c: Add add_syms_addr_command to exec_ops, so you can
2302 load symbols at any address while examining an exec file.
2304 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2306 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
2307 for printing the float info is host-dependent, not
2308 target-dependent. FIXME.
2309 * i386-pinsn.c: Move #includes to top, remove useless ones.
2310 * i386-tdep.c: Don't bother including <.../reg.h> since we
2311 don't use it (and it doesn't exist on host systems).
2313 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
2314 Convert negative numbers properly.
2315 (ieee_test): Make numbers really random; fix format arg.
2317 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
2318 * core.c (core_detach): Unpush core_ops, which might not be on
2319 top. We used to just pop the top, which broke things. Don't
2320 need dont_repeat() any more.
2321 (core_file_command): Psst! Don't repeat it.
2322 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
2323 * expprint.c (print_subexp): Avoid switch fallthru on
2324 BINOP_ASSIGN_MODIFY, so we can print += and such.
2325 * frame.h: Fix typo.
2326 * inflow.c (kill_command): After killing inferior, print our
2327 current frame in the core file, if we have one.
2328 (generic_mourn_inferior): When inferior dies, either select
2329 the current frame (in the new target, e.g. core file), or
2330 set both the current and selected frames to NULL.
2332 Changes from Peter Schauer.
2334 * infptrace.c: Avoid <sys/ptrace.h> on USG.
2336 * Make all file names fit in 14 characters (sigh and damn!):
2337 mv hp300hpux-xdep.c hp300ux-xdep.c
2338 mv symmetry-xdep.c symm-xdep.c
2339 mv symmetry-tdep.c symm-tdep.c
2340 mv convex-opcode.h convx-opcode.h
2341 mv tm-vxworks960.h tm-vx960.h
2342 mv tm-vxworks68.h tm-vx68.h
2343 mv Makefile.srcdir Makefile.sdir
2344 mv gdb-int.texinfo gdbint.texinfo
2345 mv remote-sa.m68k.shar rem-m68k.shar
2346 mv remote-multi.shar rem-multi.shar
2347 * Makefile.dist, README, config.gdb, convex-pinsn.c,
2348 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
2349 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
2352 * command.c (user_info_1, user_info): New command for listing
2353 the user-defined commands.
2355 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2357 * dbxread.c (really_free_pendings): Clear file_symbols
2358 and global_symbols after freeing them; otherwise, running
2359 this function twice (if it appears twice on the cleanup
2360 chain), we try to free things twice.
2362 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
2363 based on text_addr (the address of text in core), not on addr (the
2364 offset between text in the .o file and in core). This change
2365 is from Peter Schauer.
2367 * main.c: Define ALL_CLEANUPS as a cast of zero.
2368 (return_to_top_level): Use it.
2369 (main): Do all cleanups after each command run as part
2370 of the gdb startup sequence. Also do all cleanups before
2371 entering the command loop, and every time we exit the command
2372 loop and reenter. Before, the cleanups from the startup sequence
2373 were being left undone until the first error!
2374 (command_loop): Rename do_nothing cleanup to command_loop_marker
2375 so we can see it easily when examining the cleanup chain.
2376 (init_signals): Add another do_nothing for signal handling.
2377 (quit_command): Only try to kill target if it has execution.
2378 Problems in the target stack got us into a state where
2379 inferior_pid was nonzero but none of the targets had execution.
2380 In this state you couldn't exit gdb.
2382 * dbxread.c: Two changes from Peter Schauer.
2383 (echo_command): Fflush output after an echo command.
2384 (show_history): Pass all args to cmd_show_list.
2386 * utils.c (init_malloc): Call mtrace to turn on tracing
2387 if the environment variable MALLOC_TRACE is set to a file name.
2388 * mtrace.c: Add source file which provides a log of every malloc,
2389 free, and realloc to a trace file.
2390 * mtrace.awk: Add source file which analyzes the trace file.
2391 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
2392 (VERSION): Roll to 3.94.3.
2394 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
2395 (check_duplicates): Don't bother with watchpoints.
2396 (set_raw_breakpoint): Comment about danger of this routine.
2397 (watch_command): Parse and eval all args before calling
2400 * solib.c (find_solib): Avoid error in referencing memory to
2401 see if any more shared libraries have been added. This is
2402 particularly useful if the target has terminated. Bug reported
2405 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
2406 in bringing up 3.94.2 on the Sun-3.
2408 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
2409 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
2410 expression (in scope) before reenabling watchpoint.
2411 * signame.c (init_sigs): Add missing declaration of i, fix
2412 sys_siglist declaration.
2413 * source.c (list_command): Fixed range computation to use
2415 * stack.c (backtrace_command): Do not allow command if target has
2416 no stack, print informative error message.
2417 * target.c (target_command): Do not write into command line
2418 because this fails if the target command is used in a user defined
2419 command. [This change was enhanced by gnu to support any-
2420 unique-prefix matching on target names.]
2421 * valops.c (value_struct_elt): Avoid infinite loop on an
2422 erroneous attempt to print the member of function (try p main.p).
2424 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2426 * expread.y (name_no_typename): Avoid reduce/reduce errors
2427 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
2428 Since the GDB parser really doesn't use name_no_typename in a
2429 name-only context, the parser can't tell the diff between
2430 names and numbers here. Avoid allowing a name_no_typename
2431 to be a NAME_OR_*INT to resolve the conflict.
2433 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2435 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
2437 * valprint.c (val_print_fields): bitfield printing didn't handle
2438 byte order. Indirect through a few more fns to cope.
2440 * values.c (modify_field): also cope with byte order.
2442 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2444 Cleanup for release 3.94.2:
2446 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
2447 include files. Roll version to 3.94.2.
2449 * coffread.c (init_stringtab): Read length into unsigned char
2450 array before swapping; don't assume 32-bit longs.
2452 * target.c (target_info): Don't bother with get_sym_file, just use
2453 the symfile global variable.
2454 * symtab.h, symfile.c (get_sym_file): Delete it.
2456 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
2457 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
2458 (read_type): Replace one more error() with complain().
2460 * mipsread.c (parse_partial_symbols): Replace printf with complain.
2462 * i960-tdep.c: Fix copyright attribution.
2464 * config.gdb: Quote all backquotes in doublequotes. You can
2465 quote me on that. BSD 4.4 shell found this one.
2467 * infptrace.c (throughout): The third argument to ptrace is an
2470 * infrun.c (wait_for_inferior): When program has terminated, we
2471 have to call target_terminal_ours before we pop that target off
2472 the stack (e.g. before a call to target_kill or
2473 target_mourn_inferior). This fixes problem where a program
2474 terminates, then GDB stops for (tty output) and you have to type
2475 "fg" to the shell to resume it. FIXME: This code for what to
2476 do after termination really should be in normal_stop instead.
2478 * gdbcore.h (read_memory_check): Change declaration; it changed
2481 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
2482 4.4 prereleases, this avoids a bug in their sgtty compatability
2484 * remote.c: Use terminal.h rather than hand-rolling the same.
2486 * signame.c, signame.h (psignal): Arg is unsigned, not int.
2487 * utils.c (strsave, strstr): Fix arg types.
2488 * valprint.c (val_print): lint
2490 MIPS symbol table support from Per Bothner:
2492 * symfile.c (symtab_fns): Remove initializer table that needs to
2493 be hacked for each new symbol file format supported.
2494 (add_symtab_fns): New function, chains symbol table
2495 handlers into the global list.
2496 (symfile_init): Search this list.
2497 * symfile.h: Add next pointer, declare add_symtab_fns.
2498 * coffread.c (_initialize_coffread): Call add_symtab_fns.
2499 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
2501 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
2502 symbol *). Thus, we no longer need the hack to trash
2503 pst->filename. Good, since that hack confused code in symfile.c!
2505 (reorder_symtabs, destroy_all_symtabs): Removed static
2506 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
2507 Instead, the latter now uses a temporary array (stack-allocated
2508 from an obstack, and then freed).
2510 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
2511 haven't been set in the outermost stBlock of a procedure. This was
2512 a problem with f77 binaries on Ultrix 4.?.
2514 (new_symtab, new_symbol, new_type): Continue changing code to use
2515 obstacks more and otherwise conform to dbxread internal style.
2516 Made the free_code of symtabs be free_linetable (as in dbxread)
2517 instead of free_contents. This implies memory leaks when reading
2518 a new symbol table, until the conversion is finished. Did change
2519 (struct symbol) and (struct type) to be allocated on the
2520 symbol_obstack. Blocks and blockvectors are among the things
2523 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
2524 tested much, but it solved one problem (reported by Meissner), and
2525 cleans up some other things. The problem happened when an
2526 included file contains actual code (functions) and not just
2527 definitions. The mips coff is a little inconvenient there, since
2528 it may cause a procedure to be mapped to the wrong psymtab.
2530 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
2531 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
2532 this will need work for the new core paradigm.
2534 Opcode patches from the net:
2536 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
2537 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
2538 missing altogether - they are added here. From Bruce Bauman.
2539 * mips-opcode.h: The low mask for C0 instructions was too small.
2540 From Garrett Lau. I modified the fix to check the entire 32-bit
2543 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
2546 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2548 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
2550 * dbxread.c (read_type): Pointer subtraction (value_sub in
2551 valarith.c) sometimes failed because the types of the
2552 pointers being subtracted were not identical.
2553 These differed because dbxread.c was allocating pointer types
2554 using dbx_alloc_type+smash_to_pointer_type instead of
2555 lookup_pointer_type. I failed to find a justification for the
2556 former, so I changed it to use the latter. Similarly, I
2557 replaced smash_to_function_type by lookup_function_type,
2558 and smash_to_reference_type by lookup_reference_type.
2560 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
2561 _initialize_mipsread): corresponding changes.
2563 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
2565 * source.c (mod_path): Do tilde_expand on each component of the path,
2566 rather than on the (list of) paths as a whole.
2567 (print_source_lines): Set first_line_listed in addition to
2568 current_source_symtab and current_source_line. If the source was
2569 not findable, after a "dir" command to fix the problem,
2570 a "list" would get the wrong lines.
2572 While I was there... (gnu):
2574 * dbxread.c (read_type): Change error to complaint.
2576 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2578 First attempt at detailed understanding of symbol table memory alloc.
2580 * dbxread.c (dbx_symfile_read): Free our string table if we
2581 aren't the mainline. Free the "info" struct since we're done with
2583 (init_psymbol_list): Free any previously allocated psymbol lists.
2584 (): FIXME: Should realloc-down the psymbol lists when done reading
2585 the main symbol file?
2587 * symmisc.c (free_symtab): Free fullname field too.
2589 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
2590 (REGISTER_ADDR): Make result type unsigned int.
2592 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
2593 define REGEX must also define REGEX1 (its dependency).
2595 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2597 * tconfig/i960: No longer works, points you at vxworks960 or
2600 * xgdb.c, XGDB-README: Remove file. Users can get the much
2602 * Makefile.dist: Remove all trace of xgdb.
2604 * breakpoint.c (breakpoint_1): Pass demangle arg to
2605 print_address_symbolic.
2606 (clear_breakpoints): Remove unused function.
2607 (breakpoint_re_set_one): Guts of breakpoint_re_set.
2608 (breakpoint_re_set): Use catch_errors to do them all anyway.
2610 * gdb-int.texinfo (Host versus Target): Add section on what is
2611 a "host" feature versus what is a "target" feature.
2613 * infcmd.c (path_command, path_info): Handle the PATH variable
2614 (object search path) as conveniently as the source search path.
2615 * environ.c (set_in_environ): Set some vars in GDB's environment,
2616 in addition to the child's. PATH, G960BASE, G960BIN for starters.
2617 * source.c (mod_path): New function, from guts of
2618 directory_command, modifies a path. Used by path_command.
2619 (directory_command): Call it.
2620 * defs.h (strsave): Declare.
2622 * utils.c (sevenbit_strings): Add new printing option.
2623 (printchar): Use it.
2624 (strsave): Provide this handy helper routine.
2625 (set_width_command): Rename set_screen_width_command.
2626 (_initialize_utils): "set screen-width" => "set width";
2627 "set screen-height" => "set height"; add sevenbit-strings.
2629 * infcmd.c (do_registers_info): Print floating point registers
2630 in raw hex as well as float format, regardless of whether it is
2631 a "virtual" convertible register.
2632 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
2633 regs as a double, just in case it's being used that way.
2634 * values.c (unpack_long): Comment on array/function coercion.
2635 (unpack_double): Argument is in target byte order now. For
2636 integer arguments, just call unpack_long and float the result.
2637 * m68k-tdep.c: include defs.h for "const" handling.
2638 * remote-nindy.c: Use ieee-float stuff.
2639 (nindy_fetch_registers): Unpack double regs to host double, then
2641 (nindy_store_registers): Pack extendeds to host double, flip
2642 around by misusing unpack_double, send as target double.
2644 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
2645 zero, as when stopped at the first instruction of a process.
2647 * blockframe.c: Fix filename in comment (param.h => tm.h).
2648 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
2649 * tm-68k.h: Fix typos.
2651 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
2653 Changes from a bringup on the DEC Vax under Ultrix 4.0.
2655 * coredep.c (fetch_core_registers): Pass end-address of register
2656 section to register_addr as expected. Don't call supply_register
2657 if we'd just pass it garbage.
2659 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
2661 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
2663 * target.c (push_target, target_info): Cast enums to int for < or
2666 * stack.c (print_frame_info): Identify source file & line
2667 even if we can't print it.
2669 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
2671 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
2673 Clean up IEEE floating point support.
2675 * ieee-float.h: New file.
2676 * ieee-float.c: Write real routines to convert between host
2677 doubles and various target IEEE extendeds.
2678 * m68k-xdep.c: Eliminate assembler code for extended floats.
2679 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
2680 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
2681 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
2682 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
2683 double_to_ieee_extended.
2684 * i960-tdep.c: Define ext_format_i960.
2685 * m68k-tdep.c: Define ext_format_68881.
2686 * sparc-tdep.c: Define ext_format_sparc, though unused.
2687 * Makefile.dist (HFILES): Add ieee-float.h.
2688 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
2691 Obsolete the "coffstrip" program in favor of using BFD's strip.
2693 * nindy-share/coffstrip.c: Remove file.
2694 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
2695 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
2696 * tconfig/nindy960: Remove reference to coffstrip.o.
2698 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
2700 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2702 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
2703 * dbxread.c: Remove static symfile_bfd.
2704 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
2706 * inftarg.c (child_detach): Pop the child_ops vector if the
2707 detach is successful.
2708 * remote-nindy.c (nindy_create_inferior): Don't push a new
2709 nindy_ops since nindy uses the same one for execution and memory
2711 * core.c (core_ops): Use child_attach and child_create_inferior
2712 rather than default attach and create_inferior functions.
2714 Handle floating point registers in core files.
2716 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
2717 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
2718 This version untested since BFD doesn't yet support sun3 core
2720 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
2721 conventions. Fix comments and style. This version has not
2722 been compiled yet, since we have no HP inhouse.
2723 * core.c (get_core_registers): Look for two sections, ".reg"
2724 and ".reg2", and pass both to fetch_core_registers sequentially.
2726 Revise directory path yet again.
2728 * source.c (forget_cached_source_info): Not static any more.
2729 (init_source_path): New default source path is "$cdir:$cwd".
2730 (dir_command): Handle variable arguments ($cdir, $cwd).
2731 (source_info): Print "Compilation directory" rather than
2732 "Originally compiled in" to remind people of $cdir.
2733 (openp): If the path contains $cwd, use current directory.
2734 (open_source_file): If compilation directory is known, replace
2735 first $cdir in path with the compilation directory.
2736 (print_source_lines): Even if we can't print the lines, set the
2737 current symtab and line for future commands like "info source" or
2738 "breakpoint". Also, error message now contains the file name,
2739 line number, and file access error message.
2740 (_initialize_source): Fix help text to describe changes.
2741 * main.c (cd_command): Forget cached source info when we chdir.
2742 * utils.c (strstr): Add simple implementation.
2744 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
2746 * coffread.c (read_one_sym, init_linetable, init_stringtab):
2747 Byte-swap COFF symbol tables if necessary when reading them in.
2748 Use complain() to replace error message in one spot. Needs
2749 corresponding change in bfd/coff-code.h to make some symbol
2750 swapping routines non-static.
2752 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
2754 Merge changes from Eirik Fuller, for UTek.
2756 * defs.h (errno): Add declaration.
2757 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
2758 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
2759 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
2760 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
2761 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
2762 declarations of errno.
2764 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
2766 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
2767 <rpc/rpc.h> and <rpc/types.h>.
2769 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
2771 * i960-tdep.c (examine_prologue): Add new argument limit,
2772 which stops the scan at the end of the prologue, or at the PC.
2773 This fixes a problem where it walks down into the code for the
2774 user's statements if that code looks like function prologues.
2775 Mark Fox and I have been bouncing this code back and forth, making
2776 small changes to it. Callers changed to match.
2778 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
2780 Cleanup for gdb-3.94 release final:
2782 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
2783 the .c files from vx-share and nindy-share, from the various
2784 macros, since they are not found via ALLDEPFILES.
2785 (SFILES): Add tm-i960.h.
2786 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
2787 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
2789 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
2790 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
2792 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
2794 * am29k-tdep.c: Add contribution line.
2795 (examine_prologue): Cache information about function prologues in
2796 the misc-function-vector to avoid lots of references over the
2797 serial line while examining instructions.
2799 * core.c (core_close): New function made from cleanup_core.
2801 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2802 remote-vx.c, remote.c, target.c, target.h,
2803 Update target_ops vector to add attach, close, and load entries.
2804 Use add_syms_addr_command, not add_file_addr_command, for
2805 add_file. Break out close routine from existing code.
2807 * dbxread.c (really_free_pendings): Don't free pending_blocks;
2808 they are in an obstack.
2809 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
2811 (define_symbol): Add symbol type parameter; change callers;
2812 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
2813 it to influence the symbol class on the i960.
2814 (define_symbol): Swap LOC_CONST's into target byte order.
2816 * exec.c (exec_close): New function.
2817 (exec_file_command): Call it.
2819 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
2820 Fix byte order of frame pointer.
2821 (read_var_value): Result of 0 if var's value can't be found,
2822 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
2823 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
2824 (locate_var_value): Use read_var_value and use its lazy address
2825 as the location of the var's value. Lint.
2827 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
2830 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
2831 obsolete Intel versions in favor of vxgdb versions.
2832 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
2833 code dealing with byte order of values, which Intel did in host byte
2834 order rather than gdb-4's target byte order.
2835 (i960_frame_chain_valid): Move to nindy-tdep.c.
2836 (examine_prologue, skip_prologue, frame_find_saved_regs,
2837 frame_args_address, leafproc_return, saved_pc_after_call,
2838 pop_frame): Add vxgdb versions from Mark Fox.
2839 (examine_prologue, frame_struct_result_address): Add code
2840 to deal with the saved value of G13 (struct return address
2842 (frame_args_address): Modify Mark's version to prefer the
2843 saved value over the current value in the topmost frame.
2844 Cache result in the frame info to avoid performance hair in
2846 (print_fault): Add gdb960 code for printing faults.
2847 (_initialize_i960): Actually call check_host.
2849 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
2850 add stub routines. FIXME, these currently just return zero!
2852 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
2853 (attach_command): Call target_attach, not target_open, now.
2855 * infrun.c (normal_stop): Make global, not static, for vx_attach.
2856 (child_attach): Rename from child_open.
2857 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
2858 don't confuse it with a zero step_resume_break_address.
2860 * inftarg.c (child_detach): Eliminate inferior_pid test.
2861 (child_files_info): Clean up message a bit.
2862 (child_ops): Use child_attach, not child_open, to attach.
2864 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
2865 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
2866 findvar.c to here, since it depends on the contents of the
2867 shadow_contents of breakpoints, but keep if #if 0 since it is
2870 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
2873 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
2874 (ptype_command, display_command): Eliminate have_inferior_p and
2875 have_core_file_p in favor of target_has_stack or
2876 target_has_execution.
2877 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
2878 code for actually finding the values of arguments, though we still
2879 keep track of the maximum stack offset for use in printing unnamed
2880 arguments. Handle missing FRAME_ARGS_ADDRESS.
2882 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
2883 (struct nindy_regs): Define registers passed to/from nindy.
2884 (nindy_fetch_registers, nindy_store-registers): Translate between
2885 nindy and GDB formats for the registers.
2886 (dcache_init): Statically allocate the cache, since it was being
2887 allocated by a malloc that was never freed anyway.
2888 (nindy_create_inferior): Error, not core dump, if no exec file.
2889 (nindy_before_main_loop): Use target_load, not target_add_file.
2891 * remote-vx.c (net_load): Specify large timeout for load
2892 requests. Allow user to break out with INTERRUPT.
2893 (net_break): Remove useless code, clean up. Change callers.
2894 (parse-args, skip_white_space, find_white_space): Clean up arg
2895 parsing to cope with quoted strings.
2896 (net_wait, net_quit): Never call error, just return status.
2897 (vx_read_register, vx_write_register): Cleanup status checking.
2898 #ifdef the code based on which CPU we are using (960 or 68k),
2899 FIXME, this should be completely general but it isn't yet.
2900 (vx_xfer_memory, vx_resume): Cleanup status checking.
2901 (vx_run_files_info): Improve message.
2902 (vx_load_command): Renamed from vx_add_file_command. Allow load
2904 (net_ptrace): Remove unused routine.
2905 (vx_wait): Adopt code from vxgdb960 to cope with broken
2906 connections to target machine and prompt to disconnect. Remove
2907 debug printouts. Map some EVENT_'s to SIGnals.
2908 (add_symbol_stub, vx_open): Print names of object files we found,
2909 and "ok" if we read their symbols OK. Clarify output in general.
2910 (vx_attach, vx_detach, vx_kill): Add these commands.
2911 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
2912 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
2913 "info files" output, and create_inferior, since we already have
2916 * stack.c (frame_info): Replace Frame_unknown with 0.
2917 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
2918 (return_command): Pop until the PC matches as well as the FP,
2919 so it works even if the FP is shared with another function,
2920 as in "frameless" or "leaf" procedures.
2922 * symfile.c (load_command): renamed from add_file_target_command.
2923 (add_syms_addr_command): renamed from add_file_addr_command.
2924 (add_syms_command): Stub to call target_add_syms.
2925 (_initialize_symfile): Change command names and descriptions,
2926 add-file => add-syms, and load from alias to its own command.
2928 * target.c (kill_or_be_killed, maybe_kill_then_attach,
2929 maybe_kill_then_create_inferior): Default for attempts to start
2930 a process, if one is already running, is to ask about killing
2931 it and retry if yes.
2932 (upstack_create_inferior): #if-0 it, strata obsolete it.
2933 (push_target, unpush_target, pop_target): to_close() a target
2934 before unstacking it.
2935 (target_info): Renamed from target_files_info.
2936 (_initialize_targets): Rename "i files" as "i target", accessible
2939 * target.h: Improve comments about the target_ vectored routines.
2941 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
2942 Convert commenting style to standard GNU style.
2943 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
2944 (SKIP_PROLOGUE): No longer a no-op.
2945 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
2946 (*_REGNUM): Sort register numbers.
2947 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
2948 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
2949 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
2950 are now 10 byte extendeds, not 8 byte doubles.
2951 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
2952 for nindy versus vxworks targets. FIXME, this should possibly go
2953 in the target vector.
2954 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
2955 frame_saved_regs and arg pointer with each frame.
2956 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
2957 (FRAME_ARGS_ADDRESS): Use cached result.
2958 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
2959 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
2960 (PRINT_RAMDON_SIGNAL): Call print_fault.
2961 (POP_FRAME): Now works.
2963 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
2964 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
2965 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
2966 (ADDITIONAL_OPTION_HANDLER): use target_load, not
2969 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
2970 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
2972 * valarith.c (value_subscripted_rvalue): Avoid handling
2973 floats and doubles specially; it gave alignment errors. Lint.
2975 * valops.c (value_of_variable, value_of_this): Error if unknown
2978 * valprint.c (print_floating): Bcopy rather than pointer-deref,
2979 to avoid alignment problems.
2980 (value_print): Handle unknown value address.
2981 (cplus_val_print): Two args are ignored; remove them. Change caller.
2982 (val_print): Use unpack_long rather than pointer-deref.
2985 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
2986 to avoid alignment problems.
2987 (value_being_returned): Error if return value unknown.
2988 (set_return_value): Add bogosity warning, FIXME. *
2990 * TODO: A woman's work is never done.
2992 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
2993 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
2994 Add ieee-float.o to OBS.
2995 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
2996 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
2997 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
2999 Changes to generalize the VxWorks RPC protocol slightly, to handle
3000 i960 as well as 68000.
3002 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3003 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3004 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3005 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3006 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3007 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3008 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3009 so they will move in target byte order rather than network
3010 byte order (happens to be the same).
3012 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3014 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3016 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3019 Add contribution lines to various files, showing where they
3022 * breakpoint.c (break_insn, check_break_insn_size,
3023 read_memory_nobpt): Remove to mem-break.c.
3025 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3028 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3029 entry has bad register number. This change is not
3030 tested in this release, FIXME.
3032 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3035 * value.h: Force value's contents field to be aligned to hold
3036 at least a double or a long long (if supported). This avoids
3037 doing bcopy's in and out of the contents field.
3039 (step_1): Avoid coredump under obscure circumstances when we
3042 * symtab.h (misc_info): Add field to misc function vector for
3043 any kind of cached information the target code desires. AMD
3044 29000 uses this to avoid repeating examine_function_prologue's.
3046 * coffread.c: Lint. Remove static symfile, read_section_header.
3047 core.c (have_core_file_p): Lint: remove.
3048 expprint.c (print_subexp): Lint.
3049 infptrace.c, valops.c, valprint.c: lint.
3051 Roll in changes from vxgdb-5.0.1:
3053 * symtab.h: Comment byte order of each address class. Add
3054 LOC_LOCAL_ARG for frame-relative args (960).
3055 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3056 symtab.c, symmisc.c: ditto.
3058 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3060 * remote.c (remote_resume): Error if resume with a signal.
3062 * symfile.c (prim_record_misc_function): Clear misc_info.
3063 (fill_in_vptr_fieldno): Check stub type of arg.
3065 * valops.c (value_cast): Avoid looking up names of types whose
3066 name we don't know, to prevent coredump. Sun CC produces typedef
3067 rtx and the name of *rtx is zero...
3069 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3071 Roll in changes from final AMD 29000 port (Tiemann).
3073 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3074 for ../include/a.out.encap.h. This might not work now that BFD
3075 is separately compiled. Instead, BFD support for encap will have
3076 to translate machine type 29k into the right COFF_MAGIC.
3078 * infcmd.c: Remove references to inferior_pid that aren't used
3079 in actual ptrace calls; use target_has_execution, etc.
3080 (have_inferior_p): Remove function.
3081 (program_info): Print target info rather than "process number";
3082 avoid gratuitous messages unless from_tty.
3083 (run_stack_dummy, finish_command): Set proceed_to_finish.
3084 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3085 main.c: Lint. Lose have_inferior_p().
3086 inferior.h (have_inferior_p): Remove, lint.
3087 (proceed_to_finish): Add flag to ask that all regs be saved
3088 by normal_stop, for the few commands that need it, speeding up
3089 serial I/O. Add comments to stop_registers.
3091 * remote-eb.c: Remove newline from breakpoint message we grep
3092 for. Never time out when running the user program.
3096 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3098 Roll in changes from vxgdb-5.0.1:
3100 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3101 symbol in its raw form, we are processing an unlinked ".o" file.
3102 See if the target environment has assigned it an address, using
3103 target_lookup_symbol (VxWorks does), and enter it into the symtab
3106 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3107 68k versions for a simpler version that assumes zero FP at bottom.
3108 Fixes bug of truncated stack reports.
3110 * target.h (target_lookup_symbol): Define this routine's args
3111 and result, finally.
3113 * target.c (nosymbol): Default routine for target_lookup_symbol.
3114 (target_default): Default lookup_symbol and call_function too.
3115 (files_info): Only print has_all_memory warning if a non-dummy
3118 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3119 vx_convert_from_virtual): If target does not have floating point,
3120 zero register "values", and avoid doing cross-net conversions.
3121 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3122 (vx_open): Rearrange code that attaches to target and reads
3123 symbols for all loaded modules, to work if some of the modules
3124 are not accessible. Add symbol_stub() and add_symbol_stub()
3125 as callbacks from catch_errors(). Allow connect attempt to be
3126 interrupted painlessly with ^C (FIXME, there are still some bugs
3127 if the interrupt happens during symbol reading.). Print
3128 final message with puts_filtered, since symbol messages are
3133 * main.c (catch_errors): Only print errstring if non-null.
3134 (command_loop): Avoid an ioctl per command to test ISATTY.
3136 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3137 (vx_xfer_memory): Return correct result!
3138 (vx_files_info): Indicate whether target has float or not.
3139 (vx_lookup_symbol): Complain, not error, if target gone.
3140 (vx_open): Print "Connected" msg before disabling immediate-quit.
3141 [FIXME: lookup_symbol and vx_open changes need testing.]
3143 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3144 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3145 contributor lines and update copyrights to 1991.
3147 Changes from an attempted H-PUX host port:
3149 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3150 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3151 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3152 * remote-vx.c: include <sys/time.h> for HPUX.
3153 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3154 "core_file_command" routine to BFD regime. May not work yet.
3156 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3158 * xgdb.c: Replace X10 version with some VJ version.
3159 (FIXME: Its copyright assignment is not on record.)
3160 * xgdb.c: Update include files to X11R4 (Xaw crud).
3161 (xgdb_display_source, create_text_widget): fix call to
3162 get_filename_and_charpos. Rewack source window stuff for X11R4
3163 (gleaned from include files, and "nm's" of binary libraries, since
3164 I had no doc available).
3165 (append_selection, append_selection_word): Disable with FIXME
3166 since R4 changed interface here.
3167 (create_buttons): Add back the old set of buttons.
3168 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3170 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3171 Roll VERSION to 3.94 (not yet final though).
3173 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3175 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3176 obstack_int_grow, obstack_int_grow_fast): Eliminate
3177 cast on left of assignment, which gives MIPS cc fits and is
3180 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3181 F_ALIAS. Use printf, not fprintf, when not passing a file
3183 (compare_opcodes): Check that identical instructions have
3184 identical opcodes, complain otherwise.
3186 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3187 was reported by Roland McGrath.
3188 (unimp): Only match if exactly zero instruction. (Roland)
3189 (branches and traps): Generate all variations of these
3190 instructions with macros, based on a single call that defines
3191 each condition name and its binary representation.
3192 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3194 * valprint.c (val_print_fields): Take, and use, format parameter.
3195 This means that "p/x struct" again prints the elements in the
3196 desired format. Changed callers.
3198 * stack.c (frame_info): Use filtered output, and indicate wrap
3199 points. Remove kludgy formatting designed to avoid line wrap.
3201 * utils.c (wrap_here): If the line is already full (because
3202 we had printed a long indent or long wrapped string), do an
3203 immediate newline-and-indent.
3205 * m68k-pinsn.c (print_insn_arg): Bugfix from
3206 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3207 instruction is incorrectly disassembled as bkpt #8.
3209 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3210 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3211 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3212 and then will dump core (sometimes). I traced it back to an
3213 uninitialized symfile_name in psymtab_to_symtab.
3214 (const_vol_complaint): Add quotes to message.
3215 (define_symbol): Only believe line number if gcc_compiled.
3216 Avoid allocating symbol if we will not return it.
3218 Add target strata support so that newly established targets go
3219 into their right place in the target stack (e.g. a new exec file
3220 doesn't wipe out the ability to access the running process).
3222 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3223 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3224 and initialize it properly in all the targets.
3226 * target.h: Document strata. Change return type of push_target.
3228 * target.c (nomemory): new function for dummy memory access.
3229 (tcomplain): Rename complain, now also used in symfile.c.
3230 (push_target): Push targets within strata. New return value shows
3231 whether new target is on top of stack or not. Always keep dummy
3233 (target_files_info): Ignore dummy target.
3235 * core.c (core_open): Warn user, and skip accessing file, if the
3236 core target is not the topmost target in the stack.
3237 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3240 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3241 target_ops, it doesn't belong there since we have no regs there.
3242 Change name of target from machine => memory to clarify.
3244 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3246 * Freeze version 3.93 for release.
3248 * Makefile.dist: Handle vx-share and nindy-share subdirs
3249 properly when building gdb.tar.Z.
3251 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3252 printed in various places, so I could change just one copy.
3254 * dbxread.c, coffread.c: Change references to bfd->iostream
3255 to cast to FILE *, now that BFD avoids needing types defined
3256 in other header files.
3258 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3260 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3261 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3262 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3263 (actually gcc -Wall).
3265 * dbxread.c: Remove first_global_sym, last_global_sym, since
3266 they are never referenced.
3268 * defs.h (baud_rate): Declare.
3269 main.c: Define it, and add the -b option to set it.
3271 * gdb-int.texinfo: Add text on how to define a new host or target
3272 architecture, prompted by Per Bothner's questions about MIPS
3275 * gdb.texinfo: Document "complaints". Change doc of -q since
3276 gdb no longer prints the copyright and blurb if you specify a file
3277 name to be debugged (just like Emacs). Add doc for Nindy-specific
3278 command line flags for specifying target serial port and such.
3279 Update copyright to 1991.
3281 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3282 has taken over for us the job of ripping up executable files. The
3283 crud caused Per Bothner's port to not compile.
3285 * infrun.c (normal_stop): Avoid printing "Program exited
3286 normally" if we are in batch mode. This allows a GDB which
3287 executes a program on a target system, to behave like a Unix
3288 command (input from stdin, output to stdout, no extraneous
3291 * main.c (main): Allow additional machine-dependent command line
3292 options to be specified with the ADDITIONAL_OPTIONS,
3293 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3294 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3295 processing to occur just before the main loop with
3296 BEFORE_MAIN_LOOP_HOOK.
3297 (main): If a "core file" argument is specified, and it is not a
3298 core file, try it as a process ID to attach.
3299 (symbol_completion_function): Attempt to cope with
3300 "show screen-" TAB, not very successfully. This needs more work,
3302 (batch_file): New function, returns whether we are reading
3303 commands from an interactive tty on stdin, or from somewhere else.
3304 Called by normal_stop since it doesn't get from_tty passed down
3305 to it like many commands do.
3307 * remote-nindy.c: Handle command line options for nindy
3309 (nindy_before_main_loop): Prompt user for tty name if they
3310 don't specify it before getting to the interactive command loop.
3312 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3313 and -r command line options. Also add hook before main loop
3314 to make it easy to specify a tty.
3316 * TODO: More things to do, one done.
3318 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3320 * dbxread.c: Make complaint() calls pass pointer, not struct.
3321 Add complaints about badly formatted C++ type information
3322 (const/volatile indicator, and parse errors resulting in
3323 error_type). Fix C++ virtual member fn comment.
3324 (read_struct_type): Avoid bumping pointer if we got a parse
3325 error; this prevents our walking beyond the end of a string.
3326 Terminate loop on null char as well as semicolon.
3327 (process_one_symbol): Fix the LBRAC fix so that it uses the
3328 last previous SLINE, FUN, or SO record's PC address. C++ debug
3329 symbols did not have SLINE records in a useful order compared
3330 to the LBRAC records.
3331 (define_symbol): Handle "catch" records.
3333 * symtab.c (check_stub_type): Added new complain
3334 `stub_noname_complain' and added a consistency check to
3335 keep the debugger from crashing when finishing from an
3336 exception frame. A real fix will be needed later.
3338 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3340 * infcmd.c (attach_command): Make global.
3342 * Makefile.dist (REMOTE_OBS): Make these compile by default,
3343 but make them easy to comment out. Perhaps later they should
3344 be enabled by what CPU you configure for? FIXME.
3345 (VERSION): Roll to 3.93.
3346 (pinsn.o): Remove rule for obsolete file.
3347 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
3349 Run down a problem that manifested by printing the wrong function
3350 name in stack traces of read_ofile_symtab. Turned out that the
3351 problem was the SunOS 4.1.1 (and previous) C compiler outputs
3352 the LBRAC symbol with an address in the *data* segment, which
3353 blew our binary search through the blocks.
3355 * dbxread.c: Use the complain() facility consistently to bitch
3356 about problems in the symbol file we are reading.
3357 (finish_block): Add code to check the nesting of the blocks;
3358 complain and Procrust them to fit if wrong.
3359 (make_blockvector): Check the order of the blocks, complain
3360 [but don't cope] if wrong.
3361 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
3362 symbols to be sure their PC value is greater than the last SLINE
3363 (line number) symbol we've seen, complaining and adopting the
3364 SLINE PC value if wrong.
3366 * symfile.h (struct complaint, complaint_root, complain,
3367 clear_complaints): Add.
3368 * symfile.c (complain, complaint_root, clear_complaints): Add
3369 facility to deal with non-fatal complaints and to regularize their
3371 (symbol_file_add): Clear complaint counters to allow new complaints.
3372 (initialize_symfile): Add 'set complaints' and 'show complaints'.
3374 * dbxread.c (dbx_symfile_read): Remember the address and size
3375 of the string table for the main symbol file, so we won't read it
3377 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
3378 to avoid reading the string table yet again. Lint.
3379 (throughout): Improve filtered output, including word wrap.
3380 (read_range_type): Improve Bothner's fix to handle other types too.
3382 * utils.c: Improve line wrap implementation. Handle unlimited
3383 width by making chars_per_line unsigned.
3384 (puts_filtered): New, easy, function.
3386 * defs.h (puts_filtered): add.
3388 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
3389 call the identical sort_symtab_syms() in symfile.c instead.
3391 * expread.y: Suggest the `file' command rather than `symbol-file'.
3393 * command.h (enum var_types): Add zinteger for seroable
3395 * command.c (do_setshow_command): Handle var_zinteger. Restructure
3396 nested if's into a switch.
3398 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
3399 we did not stop because of a breakpoint (it must have been for
3400 some other reason, like a "stepi"), so don't print anything.
3402 * symtab.c: Include <sys/types.h> all the time. Now that BFD
3403 doesn't include <sys/types.h>, old SunOS's require it for
3406 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
3408 A test port of gdb-3.92.6 to the Sony NEWS.
3411 Don't normally link in remote- or vx stuff.
3412 Some of it doesn't compile, and it wastes space for 99% of the users.
3413 Remove reference to no-longer-used HAVE_VPRINTF.
3414 Fixed BFD_DEP typo to BFD_DIR.
3416 Fix cast in arg to bfd_h_getlong.
3417 Make char *prefix be const.
3418 Fix how certain range types are mapped into builtin unsigned int types.
3420 Remove 2 #includes. They cause errors (on Sony, at least),
3421 and aren't needed (they wern't in earlier versions).
3423 print_address_symbolic should never demangle labels
3424 (since it prints *assembler-level* labels).
3426 [This was superseded by the change to printcmd below.]
3429 Add some "volatile" return types to avoid warnings.
3430 If MISSING_VPRINTF add vprintf function and not just macro
3431 (since vprintf is used in printcmd.c).
3433 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
3434 (The latter isn't grokked by some PCC-based compilers.)
3436 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
3438 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
3439 * nindy-share/coffstrip.c
3440 Added some forward declarations (otherwise, gcc complains
3441 about implicit extern redefined as static).
3443 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3445 Changes inspired by Per Bothner:
3446 * printcmd.c (print_address_symbolic): Take additional parameter
3447 specifying whether to demangle.
3448 (print_address): Pass in asm_demangle to control demangling.
3449 (print_address_demangle): New fn, takes explicit arg to control
3451 * utils.c: Add new vars demangle and asm_demangle, and let them
3453 (fputs_demangled): If !demangle, just print the argument.
3454 (fprint_symbol): If !demangle, just print raw symbol.
3455 * valprint.c (val_print): Call print_address_demangle rather than
3456 print_address, to cause demangling to depend on the global
3457 rather than assembler-level demangling setting.
3458 * WHATS.NEW, gdb.texinfo: Document.
3460 * main.c (show_command): Show all settings if no arg.
3461 (initialize_main): Make "info set" the same as naked "show".
3462 * command.c (cmd_show_list): Handle prefix commands in the
3463 list, and print the name of the setting as well as its English
3464 description and value.
3466 Allow gdb functions to specify where a line should wrap if it
3467 exceeds the size of a terminal line. Use it to make the output
3469 * utils.c (set_screen_width_command): New fn, mallocs a buffer
3470 of the right size when screen width changes.
3471 (set_screensize_command, screensize_info): Remove #if 0'd fns.
3472 (wrap_here): New fn, indicates a point in the output where we
3473 should wrap the line rather than just letting it overflow at a
3475 (fputs_filtered): Implement wrapping.
3476 (n_spaces): New fn, returns a pointer to N spaces.
3477 (print_spaces_filtered): Use n_spaces.
3478 * defs.h (n_spaces): Declare.
3479 * stack.c (print_frame_info): Wrap with 4-space indent after
3480 fn name and before filename and line number.
3481 * printcmd.c (print_frame_args): Wrap with 4-space indent
3482 before each argument name is printed.
3483 * valprint.c (value_print): Wrap with no indentation before
3485 (val_print_fields): Wrap with indentation relative to nesting
3486 level before each field name.
3487 (val_print): Wrap with nesting indentation before array elements.
3488 * command.c (do_setshow_command): Avoid extra newlines,
3489 wrap with 4-space indent around values printed, end with period.
3490 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
3492 * breakpoint.c (breakpoint_1): Implement addressprint for
3493 "info breakpoints" display. Change file name and line number
3494 format to " at file:nnn" rather than " (file line nnn)".
3495 * gdb.texinfo: Document.
3498 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3500 Frozen for gdb-3.92.6 release.
3502 README, WHATS.NEW: Update for 3.92.6 release.
3504 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
3505 coffread.o from configs since it is now built by default.
3506 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
3507 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
3508 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
3509 from configs since it is now built by default.
3511 Makefile.dist: Update for release 3.92.6. Handle files that
3512 have been moved to ../include, ../getopt, or ../bfd. Add
3513 saber.suppress and tests directory. Add config.status to
3514 the release (it will say "none").
3516 coredep.c: Minor formatting fixes.
3518 These changes were made in early December but only checked in now:
3519 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
3520 nindy-share/nindy.c: lint
3521 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
3522 register values coming back from the target; we store values
3523 in target byte order everywhere.
3525 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
3527 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
3529 * valprint.c (cplus_val_print, val_print_fields): New functions,
3530 which print C++ objects. They conspire to avoid printing a
3531 virtual base class more than once, following all the twists and
3532 turns of C++ virtual base rules.
3533 (val_print): Call the above rather than do it by hand.
3535 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
3536 symbol file, not for added files like shared libs. This really
3537 needs to be generalized to a timestamp per file.
3539 * core.c (cleanup_core): Avoid coredump if no core file.
3541 * config.gdb: Accept -host or -target in place of +host or
3544 * coffread.c (find_linenos): Avoid desupported BFD interface
3545 to line numbers. We still read them manually rather than using
3546 BFD's "generic" features.
3548 * gdbrc.tex, threecol.tex: Add GDB reference card and its
3550 Makefile.dist: Add refcard to OTHERS list for creating tar files.
3552 * Makefile.dist: Eliminate use of $< in explicit targets.
3554 * readline/Makefile: Use $< rather than $*.c, which does not
3555 include the VPATH in GNU Make.
3557 * tconfig/i960-bout, tconfig/i960-coff: These are identical
3558 copies of tconfig/i960, added for global configuration
3559 compatability. All i960 versions can read both coff and b.out.
3561 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
3562 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
3565 * TODO: Think of more things to do.
3567 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
3569 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
3570 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
3571 64-bit float conversion.
3573 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
3574 equivalent to sun?os4 so global config works.
3576 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
3578 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
3580 * main.c: Only declare linesize once; declare pagesize not at
3581 all, since it is never used.
3582 (main): Clear newly allocated line before it is used.
3584 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
3586 Further stabilization for the Intel 960.
3588 * Makefile.dist: Parameterize the location of the "include"
3589 and "bfd" directories, as well as "getopt". Add symfile.c.
3590 Link in both dbxread and coffread. Fix up "make depend" to
3591 rewack the locations of include, bfd, and getopt in its output.
3593 * README: Document moving include files, improve some of
3596 * coffread.c: Move common code out to symfile.c. Change
3597 symbol_file_command style interface to use new *_symfile_init
3598 and *_symfile_read interface under BFD. Use BFD internal
3599 info to locate line table, symbols, etc.
3601 * core.c (core_fetch_registers): Rename to get_core_registers
3602 to avoid confusion with fetch_core_registers.
3603 (register_addr): Move to coredep.c, which is already machine
3604 dependent. This leaves core.c pretty clean of dependencies.
3606 * coredep.c (register_addr): Accept this routine from core.c.
3608 * dbxread.c: Move common code (with coffread.c, etc) into new
3609 symfile.c. Each psymtab now contains a pointer to the
3610 format-dependent function that knows how to read it in. Make
3612 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
3613 (process_one_symbol): Add code to complain about a "compiler bug
3614 we muzzle here", if we actually see it.
3616 * eval.c (evaluate_subexp): Insert missing "break" statements
3617 in code that determines whether a variable is an lvalue in
3618 memory, register, or whatever. I detected this via a compiler
3619 bug in which it *almost* mashed out the whole switch statement.
3621 * gdb-int.texinfo: Add minor sections on configuring gdb for
3622 release, and about the README file.
3624 * infcmd.c (registers_info): Fix formatting somewhat. Still
3625 not as pretty as before, but it handles byte swapping.
3627 * remote-nindy.c: If data cache routines are interrupted while
3628 waiting for the remote end, be sure that any uninitialized cache
3629 blocks are on the free list, not on the valid list!
3631 * symfile.h: Flesh out this header file with all the various
3632 routines and variables that have been merged in from dbxread.c
3633 coffread.c, and symtab.c to symfile.c.
3635 * symfile.c: New file, containing code common to dbxread.c,
3636 coffread.c, and some code from symtab.c. All generic code for
3637 reading symbol files should be in here now.
3638 (unrecord_misc_function): Remove unused function.
3640 * symtab.h: Remove file-reading things to symfile.h.
3642 * symtab.c: Remove file-reading things to symfile.c.
3644 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
3645 to decode i960 fault types.
3647 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
3648 target.c: Change type of the "resume" function from int to void,
3649 since its result was never used.
3651 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
3653 * main.c: Replace "stupid" with "caution"; you now "set caution
3656 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
3658 * infcmd.c (do_registers_info): Call val_print to deal with the
3659 byte order of the registers being printed. FIXME, this makes
3660 the formatting of the output uglier.
3662 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
3663 defined, call it for signals the debugger doesn't itself use.
3664 The i960 uses this for more detailed fault information.
3666 * remote.c (remote_open): If arg is null, print help rather than
3669 * sparc-xdep.c (register_valid): Avoid declaring size, since
3670 various modules will think of various sizes depending on the
3671 architecture of their tm-file. FIXME, we need protection against
3672 actually entering one of those modules, which would clobber
3673 storage if not for the target architecture compiled into gdb.
3675 * stack.c (up_command, down_command): Always print the frame
3677 (up_silently_command, down_silently_command): New commands
3680 * i960-pinsn.c (reg), i960-tdep.c: Lint.
3682 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
3683 more parameters than it used to.
3685 * findvar.c (registers): Increase slop to 256 bytes, which should
3686 protect us against even most RISC machines with large register
3688 (locate_var_value): Move declaration inside related ifdef.
3690 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
3691 throughout, to avoid throwing away buffered input from the board.
3692 (nindy_wait): Supply_register takes addr_of_value, not value.
3693 (i960_print_fault): Renamed from i80960_fault.
3694 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
3695 (nindy_store_registers): Avoid regs_changed stuff, just stuff
3697 (nindy_create_inferior): Don't bother to write PC_REGNUM since
3698 we can set the PC in the call to proceed(). Unpush nindy_ops
3699 before pushing it on top, to avoid message to user. Eliminate
3700 commentary from Unix machines that just misleads here.
3701 (reset_command): Fix error message to suggest target command.
3703 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
3705 Release 3.92.5 as frozen.
3707 Stabilize the merged release...with help from lint, Saber C,
3710 Everywhere: Add include files needed to declare return types
3711 of functions called.
3713 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
3715 * breakpoint.h: Add undeclared breakpoint functions, and some
3716 functions for display handling since I couldn't think of a better
3719 * breakpoint.c (insert_breakpoints): Make code for disabling
3720 shared library bkpts more likely to work. It's used when we
3721 rerun a program and stop before the shared library has been
3723 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
3724 cast from pointer, so it squeezes through catch_errors.
3725 (bpstat_stop_status): Fix logic broken some time ago. We now
3726 always create a bpstat if the stop address matches a breakpoint,
3727 even if we don't stop there -- just like the old code used to do
3728 before I got my fingers into it (sigh).
3729 (breakpoint_1): Print "ignore count" after "stop only if"
3730 condition, since that's how it actually works.
3731 (mention): Handle watchpoints as well as breakpoints.
3732 (watch_command): use set_raw_breakpoint and mention to do most
3733 of the work (and initialize all the fields!). Only pass one
3734 arg to parse_c_expression, since that's all it takes.
3736 * command.c (not_just_help_class_command): Rename arg to args
3737 since we ignore "unused argument" warnings on vars named "args".
3738 inflow.c (child_terminal_info): ditto.
3739 infptrace.c (kill_inferior): ditto
3740 main.c (catch_errors, version_info, quit_command, pwd_command,
3741 source_command, dump_me_command, editing_info,
3742 set_history_size_command, set_history, show_history,
3744 stack.c (locals_info): ditto
3745 target.c (target_files_info): ditto
3746 valprint.c (set_input_radix, set_output_radix): ditto
3748 * core.c: Remove old variables for handling core and exec file
3749 sections (data_start, data_end, stack_start, stack_end,
3750 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
3751 text_end, exec_data_start, exec_data_end, text_offset,
3752 exec_data_offset, data_offset, stack_offset). They're
3753 superseded the more general build_section_table and
3755 (get_exec_file): Mention the `file' command.
3756 (read_memory_check): Rename to memory_error, and only call it
3757 in the case of an actual error.
3758 (read_memory, write_memory): call memory_error.
3759 (core_fetch_registers): Register section name is ".reg".
3761 coredep.c: Remove a bunch of crud now that all this file does
3762 is pull the registers out of a core file.
3763 (fetch_core_registers): Rewrite to actually work, I hope.
3765 dbxread.c: Use a.out.gnu.h, not system a.out, now.
3766 Replace index() with strchr(). Remove all the pre-BFD macro
3767 definitions for accessing the symbol file.
3768 (struct dbx_symfile_info): Encapsulate the information that
3769 dbx_symfile_init needs to pass to dbx_symfile_read in this
3772 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
3773 dbx_symfile_discard): Rearrange symbol file reading to divide
3774 the format-specific part from the format-independent part,
3775 leaving the format-independent part such as file name expansion
3776 and opening in symtab.c. This replaces
3777 partial_symbol_file_open and partial_symbol_file_read.
3778 Symbol_file_read, add_file, add_file_target_command,
3779 add_file_addr_command move to symtab.c. Pass an explicit
3780 "mainline" flag for when reading the main symbol table, rather
3781 than relying on the offset address to be zero or nonzero.
3783 (dbx_symfile_read): Don't allow void *'s to be printed as
3785 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
3786 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
3787 macro" debug version really work.
3788 (read_dbx_symtab): Remove unref'd parameter inclink.
3789 Avoid swapping N_SLINE symbols, for speed.
3790 Merge N_TEXT!N_EXT case with the other external symbol
3791 definitions' case. Add comments.
3792 (start_psymtab): Allocate the symfile name in the psymtab on
3793 the psymbol_obstack, rather than using the caller's storage.
3794 (end_psymtab): Only allocate a dependencies list if there are
3796 (psymtab_to_symtab_2): Use BFD when reopening file to read
3797 its symbols for real.
3798 (read_struct_type): Add FIXME comments where it needs work
3800 (read_huge_number): Add FIXME about overflows.
3801 (read_range_type): Add FIXME about comparing a long to 1<<32.
3803 * coffread.c: Minor changes to move things closer to the new
3804 regime with symtab.c and dbxread.c Major work is still needed
3807 * exec.c (exec_file_command): Remove old variables (see core.c
3809 (xfer_memory): If memory transfer is right at the end of a
3810 section, don't lose.
3812 * findvar.c (get_saved_register): If value is in a real
3813 register, LVAL is lval_register, not lval_memory.
3815 frame.h: Declare print_sel_frame and record_selected_frame.
3817 gdb-int.texinfo: New file, for GDB internals documentation.
3818 Very simple, unformatted doc of cleanups is there for now.
3820 gdbcore.h: Remove obsolete variables that described a.out
3821 section addresses and offsets. (See core.c above.)
3822 Declare fetch_core_registers and registers_fetched.
3824 getopt.c: Declare char *alloca(); even on SPARC.
3826 infcmd.c (run_command): Call target_kill rather than
3828 (step_command, next_command, stepi_command, nexti_command):
3829 Declare from_tty parameter even though we don't use it.
3830 (run_stack_dummy): argument BUFFER is a char array, not
3831 a pointer to REGISTER_TYPE.
3832 (finish_command): using_struct_return needed a value *,
3833 not a struct symbol *.
3835 * infptrace.c (child_xfer_memory): To avoid dependency on
3836 where sections are in memory, try PT_WRITE_D and if that fails,
3837 try PT_WRITE_I. Most Unixes don't care which you use.
3839 * infrun.c (step_resume_break_shadow): Change to array to
3840 match other breakpoint shadow storage.
3841 (clear_proceed_status): Pass address of bpstat to
3842 bpstat_clear, not the bpstat itself.
3843 (child_create_inferior): FIXME comment about if the child
3845 (start_inferior): Remove old function.
3846 (child_open): Use target_kill rather than kill_inferior.
3847 (wait_for_inferior): Ditto.
3848 (insert_step_breakpoint, remote_step_breakpoint): Use
3849 new step_resume_break_shadow.
3851 * inftarg.c (child_wait): If all child processes die,
3852 pretend that the one being waited for exited with signal 42.
3854 * main.c (command_line_input): When scanning for comments,
3855 don't coredump on unclosed quotes.
3856 (quit_command): Use target_kill rther than kill_inferior.
3857 (_initialize_main): Rename class_user from "user" to
3860 * printcmd.c (print_command_1): Initialize "fmt" if no format
3861 is specified by the user.
3862 (print_frame_args): Only add to args_printed if we are
3863 actually fetching args from the stack (avoiding undefined
3865 (_initialize_printcmd): Remove bogus \{ from string.
3867 * remote-eb.c (eb_open): Avoid coredump on no argument.
3869 * remote-nindy.c: Bring out of Intel environment into new
3870 target environment. Remove all conditional compilation on
3871 I80960. Massive hacking throughout.
3872 (nindy_xfer_inferior_memory): New routine stolen from
3874 (nindy_create_inferior): New routine pieced together, probably
3875 not quite working yet.
3876 (nindy_ops): New target_ops struct for nindy.
3878 * remote-vx.c: Use write_memory rather than target_write_memory
3879 to get error checking.
3880 (vx_add_file_command, vx_open): Use symbol_file_add rather than
3882 (vx_create_inferior): Use target_terminal_ours...
3884 * signame.c (_initialize_signame): Always initialize, since
3885 we need the table for things other than psignal.
3887 * solib.c (solib_add): Use symbol_file_add, not add_file.
3888 (solib_address): Return boolean result rather than struct
3889 pointer which nobody else knows the type of.
3891 * sparc-tdep.c, valops.c: Use write_memory rather than
3892 target_write_memory, to get error checking.
3894 * stack.c (locals_info, catch_info, args_info,
3895 get_selected_block, frame_command, up_command): Use
3896 target_has_stack, rather than have_inferior_p or
3899 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
3901 * symfile.h: New file, defining the interface between the
3902 generic and object-file-specific symbol reading code.
3904 * symtab.c: Move generic symbol-reading interface to symtab.c,
3905 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
3906 table to map BFD targets to symbol-reading modules in GDB.
3907 Change index to strchr.
3908 (lookup_struct_elt_type): Use error() rather than hand-made
3909 simulations thereof.
3910 (lookup_partial_symbol): Speedup slightly when length == 0.
3911 (symbol_file_add): New function.
3912 (symbol_file_command): Call it.
3913 (symfile_open, symfile_init): New function.
3914 (add_file_target_command, add_file_addr_command): moved from
3917 * target.c (target_command): use target_kill.
3919 * target.h (target_files_info): Don't declare, never called
3922 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
3923 files to determine stack end address.
3925 * valarith.c (value_x_binop, value_x_unop): Change error message
3926 to be more useful. Pass proper argument to value_struct_elt.
3928 * valops.c (value_assign): FIXME comment that long long
3929 bitfields will break here.
3931 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
3932 Update `make saber_gdb' to work better.
3934 * TODO: A woman's work is never done.
3936 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
3937 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
3938 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
3939 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
3940 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
3941 valops.c, valprint.c, exec.c: Lint.
3944 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
3946 Continuing Intel 960 port merge of GDB.
3948 * Makefile.dist: Merge i960 "nindy-share" files. Rename
3949 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
3950 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
3951 Wack over "make depend" so it handles files in subdirectories
3952 vx-share, nindy-share, bfd, and in the current directory.
3954 * blockframe.c (get_prev_frame_info): Remove fatal error
3955 if stack not defined.
3957 * core.c (core_open, core_detach): New functions that handle
3958 the old "core-file" command as "target core" and "detach" instead.
3959 (core_file_command): Call them.
3960 (core_xfer_memory): Use common routine xfer_memory.
3962 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
3963 dbxread now uses bfd for everything but symbol reading itself.
3964 BFD internals are used to drag out the relevant file offsets.
3965 (partial_symbol_file_open): Change args all around for BFD.
3967 * symtab.c: Rename "value" to "val" everywhere, so we can
3969 (symbol_file_command): New command, moved from dbxread.c
3970 and coffread.c. It uses BFD to read the file, then vectors
3971 based on its type, to dbx or coff symbol readers.
3972 * symtab.h: Extern a few vars for symbol_file_command.
3974 * target.h: Breakpoint takes a char * save area, not a char **.
3976 * valprint.c (val_print): When unpacking bitfields, offset
3977 the address in gdb of the value, if it is declared with a shorter
3978 type. Remove the last "runtime kludge test" of host byte order.
3980 * utils.c: Remove old my_bfd_read routine.
3982 * stack.c (frame_info): Use target_has_stack. Print program counter
3983 register's actual name rather than "pc", since it's called the
3984 "ip" (instruction pointer) on the i960 (sigh).
3986 * target.c (target_command): Add command for selecting a target
3987 type and calling its open routine. This is used for initiating
3988 communication with a particular target, in a generic way.
3990 * tm-i960.h: Update for modern gdb. Remove semicolons from
3991 various macros. Handle reading struct return convention, and
3992 error-out attempts to return structs with the "return" command.
3993 Be sure gdb doesn't think we know how to call functions in the
3996 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
3997 to i960_xxx in lower case.
3998 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
3999 not being defined yet.
4001 * remote.c (remote_open): Call start_remote to initialize
4002 wait_for_inferior during open.
4003 (remote_xfer_inferior_memory): Return length written rather
4006 * remote-vx.c (target_command -> vx_open): Use new generic
4008 * remote-eb.c, inftarg.c, exec.c: ditto.
4010 * infrun.c: Fix comments.
4011 (attach_program -> child_open): Use new generic target command.
4012 (wait_for_inferior): Clear saved register values before target_wait,
4013 so target_wait can set some of them if convenient.
4015 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4016 Return success indicator, not void.
4017 (child_xfer_memory): Avoid fetching initial word if we'll
4018 overwrite it anyway.
4020 * infcmd.c (attach_command): Use new generic target open routine.
4021 (_initialize_infcmd): Update doc on attach and detach commands.
4022 (do_registers_info): Merge in a byte-order problem as a FIXME
4025 * findvar.c (find_saved_register): Avoid problem in current frame.
4026 (read_relative_register): Ditto.
4027 (write_register): Convert byte order on the way out.
4029 * exec.c (file_command): Add.
4030 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4031 (xfer_memory): Common function between core_xfer_memory and
4033 (exec_xfer_memory): Use it.
4035 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4037 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4038 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4039 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4041 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4043 Merge Intel 960 port of gdb, continuing...
4045 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4046 symbol_file_command): Pass from_tty arg to hush 'em up.
4048 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4049 Add magic numbers for 960 COFF format.
4051 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4053 Merge Intel 960 port of gdb, from Intel "1.2" release.
4055 CHANGE_LOG entries from their port, which was based on
4058 Thu Sep 6 11:02:22 PDT 1990
4059 Remove temp file if download is interrupted.
4061 Wed Aug 1 09:08:33 PDT 1990
4062 Now uses binary protocol to talk to NINDY.
4063 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
4064 Times out after 5 seconds when trying to talk to NINDY.
4066 Tue May 29 12:54:49 PDT 1990
4067 Added variable baud rate (-b switch).
4068 Source code reorganization.
4070 Thu Apr 26 11:09:55 PDT 1990
4071 More cleanup of batch mode; specifically, execute "-s", "-e", and
4072 "-se" switches as soon as they are encountered on the invocation line.
4074 Fri Apr 20 13:47:15 PDT 1990
4077 Thu Apr 19 09:54:28 PDT 1990
4078 Add 'reset' command.
4080 Wed Apr 18 09:48:07 PDT 1990
4081 After opening remote tty, wait for 1 second to go by without input
4082 from it before trying to talk to NINDY (fixes problems with the
4083 Heurikon HK80/V960E).
4085 Mon Apr 4 16:33:05 PDT 1990
4086 Some output was not being suppressed in 'batch' mode.
4088 Thu Mar 22 15:31:11 PST 1990
4089 Ask user if old symbol table should be deleted when new file is
4092 Allow user to run a program downloaded before gdb960 was brought up.
4094 Correct "exec-file" help message for i80960 context.
4096 Correct bug in calculating user space address: could occasionally
4097 corrupt user program.
4099 Make sure to zero low-order bits in rip's because of bug in 960CA
4100 A-step part: could cause operation faults when "next"ing across
4103 Correct bug that made it impossible to get source line numbers for
4104 code loaded at addresses higher than 0x7fffffff.
4106 Wed Jan 10 12:43:22 PST 1990
4107 Open remote tty for exclusive use.
4109 Fri Jan 5 12:14:42 PST 1990
4110 Correct disassembly (CA manual was right after all):
4111 opcode for sysctl is 0x659
4113 Mon Oct 23 12:03:04 PDT 1989
4114 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4116 Mon Oct 16 14:15:09 PDT 1989
4117 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4119 Mon Oct 2 15:56:31 PDT 1989
4121 Added 960CA disassembly support.
4123 To simplify maintenance:
4124 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4126 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4127 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4128 - made disassembly interface identical to that in gdmp960.
4132 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4134 * target.h: Allow targets to stack. Add target_has_memory,
4135 _registers, etc. Restructure memory access and "info files"
4136 to walk the target stack.
4137 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4138 target.c: Change tables to match target.h.
4139 * inflow.c (child_mourn_inferior): pop child_ops.
4140 (generic_mourn_inferior): Use new has_stack flag.
4141 * infptrace.c (child_xfer_memory): New memory regime.
4142 * inftarg.c (child_files_info): New "info files" regime.
4143 * remote-eb.c: New memory regime, new info files.
4144 * remote-vx.c: New memory regime, new info files. Now use
4145 separate targets for VxWorks attachment to machine, and
4146 actually running a process under VxWorks, since one has
4147 stack & execution & regs and the other doesn't.
4148 * remote.c: New memory regime, new info files.
4149 * sparc-xdep.c (fetch_core-registers): New memory regime.
4150 * target.c: New routines and support for stacked targets,
4151 new memory regime, new info files regime.
4154 Generalize section handling for an arbitrary number of sections,
4155 including use of the new BFD (binary file) library.
4156 * gdbcore.h: Add struct section_table.
4157 * exec.c (build_section_table): Iterate all sections and
4158 record what gdb needs to know about them.
4159 (exec_command): Use it.
4160 (exec_xfer_memory): Use the table.
4161 (exec_files_info): Print the table.
4162 * core.c (core_file_command, core_xfer_memory, core_files_info):
4164 * source.c (find_source_lines): Use bfd_get_mtime.
4165 * dbxread.c: Quick changes to make it compile with new BFD.
4166 * utils.c (error): Avoid using bfd_error in generic routines.
4168 * core.c (core_fetch_registers): Get from the ".regs" section of
4170 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4172 * inferior.h (attach_flag): Export.
4173 * infcmd.c (run_command): use new target_create_inferior.
4174 * infrun.c (child_create_inferior): Don't return result.
4175 * Makefile.dist (VERSION): 3.91.4.
4177 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
4179 * breakpoint.c (bpstat_num): Handle breakpoints which have
4180 since been deleted, such as temporary breakpoints.
4181 infcmd.c (program_info): ditto.
4183 * core.c (core_file_command): Display the frame where the core
4188 * remote-vx.c (target_command): Merge in target command from
4189 targ-vx.c. A few other cleanups.
4191 * TODO, Projects: Lots more stuff to do...
4193 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4195 Massive changes to wall off the remote-debugging interface
4196 behind a function vector. The port to handle VxWorks targets
4197 is also part of this.
4199 All files: Replace references to renamed functions,
4200 remove references to remote_debugging, remove references to
4201 have_include_file, have_core_file in favor of target_has_stack,
4202 target_has_memory, etc.
4204 * Modularize the breakpoint interface.
4205 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4206 a breakpoint instruction.
4207 breakpoint.c: struct breakpoint's shadow_contents now sized as
4209 (insert_breakpoints): Vector to target to install breakpoints.
4210 (remove_breakpoints): Vector to target here too.
4211 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4212 sparc-tdep.c (single_step): Use new breakpoint interface for
4213 the single-step breakpoints.
4214 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4215 New file, contains routines to insert and remove breakpoints by
4216 reading out the old contents and later replacing them. This is
4217 how ptrace breakpoints work, and many remote systems as well.
4219 * tm-vxworks68.h: New config file, overrides a few things for
4220 Wind River's preferences.
4222 * target.h: New file, for transfer vector used to talk to the
4223 inferior (child, attached, core, exec, remote, etc). All accesses
4224 to the thing being debugged should come through these vectors.
4225 target.c: New file, routines to handle transfer vector.
4226 (various files): Add transfer vectors XXX_ops for the various
4227 targets and pseudo-targets (core files, etc) we support.
4229 * breakpoint.c (bpstat_stop_status): Further explorations of
4230 watchpoints and why things don't work all the time.
4231 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4233 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4234 the local gdbinit if it doesn't already have it.
4236 * core.c (core_ops): add and install.
4237 Allow core debugging without exec file.
4239 * dbxread.c (free_and_init_header_files): Merge two fns.
4240 (end_symtab): Free named symbol table when a new version comes in.
4241 (read_dbx_symtab): Relocate all kinds of symbols with base
4242 address. First step toward handling different text, data, bss
4244 (add_file_addr_command): Renamed add_file_command.
4245 (add_file_command): Vector to remote handler.
4246 Add "load" as an alias for "add-file" command.
4248 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4249 non-returning functions.
4251 * exec.c: Add exec_ops, and push it as a target when an exec
4254 * infcmd.c (run_command): Pass executable file name and arg list
4255 separately when starting an inferior. Permit "run" when no exec
4256 file is specified, for VxWorks.
4257 (detach_command): Move to child_detach in inftarg.c.
4259 * inftarg.c: New file. Unix-child-specific routines, and the
4260 child_ops structure.
4262 * inferior.h (registers): Export "registers" as the way for
4263 target dependent register handlers to find gdb's local copy of
4264 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4265 since it is now used by places that want wait_for_inferior to
4266 handle the grunge but want to see every trap from the inferior.
4268 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4269 Eliminate remote_debugging hooks in terminal handling.
4271 * infrun.c: Replace start_inferior with child_create_inferior.
4272 Move all the hair of Unix shells and ptrace idiosyncracies into
4273 child_create_inferior, so remote handlers don't have to deal.
4274 Remove running_in_shell. Rename stop_after_attach to
4275 stop_soon_quietly, and use it in a few other places where we want
4276 to just call wait_for_inferior and get control back on the first
4277 trap. trap_expected now never takes a value > 1.
4278 (init_wait_for_inferior): Initialize static vars when a new
4281 main.c (gdbinit): Add new hook for .gdbinit file name, let
4282 it be overridden by config files as GDBINIT_FILENAME.
4283 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4284 Both of these are used for VxWorks gdb.
4286 mcheck.c: rename include file "gmalloc.c" to avoid problems
4287 with system include file "malloc.c".
4289 param-no-tm.h: New include file, same as param.h but does not
4290 include the default "tm.h" file. This is used in files where
4291 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4293 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4295 remote-vx.c: New file, VxWorks remote debugging support. Uses
4296 RPC routines that are shared with the target system, in directory
4299 remote.c: Vectorize remote interface.
4301 source.c: Globalize source_path, and make an alias "l" for "list"
4302 since we now have the "load" command.
4304 sparc-xdep.c: Use new param-no-tm.h.
4306 symmisc.c (free_named_symtab): Add new function from Wind River.
4307 However, ifdef it out for now while we think about what it should
4310 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4312 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4313 non-Unix-children handle this with their own code in the target
4316 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4317 source and target lists. Add vx-share to default list of include
4318 directories. Add new files to src and target lists: mem-break,
4319 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4320 ${srcdir} versions of munch and createtags are used.
4322 * valops.c (find_function_addr): Split out of call_function.
4323 (call_function_by_hand): Rename call_function; this function
4324 calls functions in the target by laboriously patching the target
4325 word-by-word with the right stack, args, regs, etc.
4328 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
4330 Handle AMD 29000 a bit better.
4332 * remote-eb.c (readchar): Mask received char log to make it readable.
4333 (remote_start): Pass arguments down to executing program.
4334 Make startaddr unsigned.
4335 infrun.c (start_inferior): Accept args, pass them to
4337 infcmd.c (run_command): Pass args down to start_inferior.
4339 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
4340 the target object file format.
4341 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
4343 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
4344 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
4346 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
4348 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
4349 * TODO: We did a few things, we have more to do though.
4351 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
4352 * inflow.c (inferior_died): Clear deferred stores.
4354 * Debug problems with dummy frames and calls to the inferior.
4355 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
4356 * sparc-tdep.c (do_restore_insn): Simplify.
4357 (sparc_frame_find_saved_regs): Simplify and fix what we find.
4358 (sparc_push_dummy_frame): Simplify and fix what we push.
4359 (sparc_pop_frame): Slightly more hair here, deciding whether
4360 we are restoring a saved PC or returning to a return address in %i7.
4361 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
4363 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
4364 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
4365 * obstack.h (chunkfun): ditto.
4366 * defs.h (xmalloc, xrealloc): ditto
4368 * utils.c (quit): Grab the terminal from the child if necessary.
4370 * inflow.c (term_status_command): Rename to term_info, change
4373 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
4374 (is_delayed_branch): Speed up.
4375 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
4376 Still missing some float ops, and needs testing.
4378 * Support for input and output radixes other than base 10
4379 * defs.h (input_radix, output_radix): Declare.
4380 * expread.y (yyparse, parse_number): Handle changes of input
4381 radix, and ambiguous names-or-numbers in radixes >10.
4382 * printcmd.c (print_scalar_formatted): Print formatted hex
4383 numbers in varying column widths.
4384 * valprint.c (val_print): Use output_format to print scalar ints.
4385 (set_input_radix, set_output_radix, set_radix): Create.
4386 (set_output_radix): Set output_format from output_radix.
4387 (_initialize_valprint): add `set radix' but leave the others off.
4389 * main.c (execute_command): Let stupid questions be turned off.
4390 (_initialize_main): Handle "set stupidity", etc.
4392 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
4393 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
4395 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
4397 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
4398 bfd stuff is still screwed up, but with some manual work, it
4401 * breakpoint.c (bpstat_do_actions): Start over if a command
4402 proceeds the inferior, since the inferior will have stopped and
4403 will need to have its new stop-actions taken care of.
4405 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
4406 compiler fits, simplify it.
4408 * gdb.texinfo (directory command): Doc new dir command.
4409 source.c (directory_command): "dir" now puts things on the front
4410 of the path, moves dups up front, and handles multiple names
4411 on the command line, inserting each one in order. It also
4412 blows away cached line and full_filename info.
4414 * stack.c (backtrace_command): Skip "more stack frames follow"
4417 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
4418 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
4419 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
4420 The only odd one was Gould NP1, which had defined vprintf to
4423 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
4424 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
4425 variable, inspect_it.
4426 valprint.c (print_string, val_print): Use the global inspect_it
4427 to indicate whether to print in Epoch style or normal style.
4429 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
4431 * printcmd.c (call_command): add an alias for the "print" command
4432 which runs expressions and doesn't print the result if void.
4433 (print_command_1): implement it.
4435 * command.c: Remove #if 0'd code. Initialize all the fields
4436 in add_cmd (). Rename do_nothing_command to
4437 not_just_help_class_command, and make it externally visible.
4438 command.h: add user_commands to struct.
4439 * main.c (define_command): Don't overload c->function with a char
4440 string as well as a function pointer.
4442 * eval.c (evaluate_subexp): Reinstall tiemann changes to
4443 calling convention of value_struct_elt () that got dropped in
4446 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
4447 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
4449 * tm-sparc.h (POP_FRAME): replace some constants with defines.
4451 * sparc-xdep.c (store_inferior_registers): defer stores to regs
4452 until a good time (e.g. when we are about to run the child),
4453 saving ptrace calls.
4454 * infrun.c (proceed): handle DO_DEFERRED_STORES.
4455 * tm-sparc.h: define DO_DEFERRED_STORES.
4457 * sparc-xdep.c (store_inferior_registers): when storing float
4458 registers, don't store stack regs too. When storing the SP,
4459 however, DO store the stack regs too. This fixes a bug in which
4460 the dummy frame is not recognized when a call_function finishes,
4461 because its frame pointer (in the stack regs) was never
4463 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
4464 even though we don't know how to read them from an inferior.
4465 valops.c (call_function): Comment about storing SP.
4467 * infrun.c (save_inferior_status): Save away the original bpstat
4468 chain so it can be restored later. Install the copied version for
4469 use by whoever saved the status. It will be blow away by
4470 restore_inferior_status, and the original chain restored. This is
4471 important for people who have pointers into the original.
4473 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
4474 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
4475 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
4478 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
4480 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
4481 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
4482 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
4484 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
4486 * Merge Mike Tiemann's multiple inheritance changes from Sun.
4487 Store the baseclasses in a type struct starting from array element
4488 0 rather than from the unusual array element 1.
4490 dbxread.c: the above.
4491 (virtual_context): Add
4492 Read new debug information about which virtual function table
4493 a virtual function is from, and store it in fn_field.fcontext.
4495 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
4496 TYPE_FN_FIELD_STATIC_P.
4498 symtab.c: the above.
4499 valops.c: the above. Handle pointer casts of object *'s.
4500 (search_struct_method): Add.
4501 (value_struct_elt): First arg is now a pointer to a value, and is
4504 valprint.c: the above.
4505 values.c (value_virtual_fn_field): Add type arg. Handle
4506 offsetting to the proper object when calling virtual fns.
4508 (baseclass_addr): Add valuep arg.
4510 * README: Document the current state of BFD config (missing).
4511 * TODO, ChangeLog, Makefile.dist: Roll version.
4512 * WHATS.NEW: Add summary of changes since 3.5.
4514 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
4516 * dbxread.c (read_struct_type): Clear bit vectors whenever
4518 symtab.c (B_CLRALL): define.
4520 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
4521 using == rather than =. Huh... This fixes the dreaded problem
4522 wherein builtin_type_int becomes TYPE_CODE_FLT.
4524 * core.c (info_files): Show the inferior pid.
4526 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
4527 already knows how to look in the source directory.
4529 * Remove psymtab hair from many places. Remove duplicated code
4530 for searching symbol tables. Hide psymtabs from most places.
4531 Make it fast to get from a psymtab to its symtab.
4533 blockframe.c (blockvector_for_pc): Remove psymtab hair.
4534 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4535 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4536 dbxread.c: export psymtab_to_symtab, make it work if called N times.
4537 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
4538 new symtab completely. New psymtabs get symtab pointer
4539 initialized to zero. Remove MI warning printf.
4540 symtab.h: Comments. Add psymtab to symtab pointer.
4541 (PSYMTAB_TO_SYMTAB): New macro.
4542 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
4543 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
4545 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
4547 (print_frame_info): Avoid special-casing symbols that have not yet
4550 * source.c (open_source_file): Quick path if we have already
4551 located the source file by its full name.
4553 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
4554 find_pc_psymtab. When a name is found in the misc function
4555 vector, search the symbol table for its mangled name, not the
4556 name that the user typed.
4558 * bfd.h: Fix missing comment terminators, make #endifs match.
4560 * valarith.c (value_less): Handle unsigned int comparisons.
4561 Add FIXME about pointer compares, which assume host and target
4562 pointers are the same.
4564 * command.c (do_nothing_command): lint
4565 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
4566 fix comments on debug symbol format for visibility. Actually set
4567 visibility of symbols.
4568 main.c (echo_command): lint; use <readline/history.h>.
4569 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
4570 obstack.h (_obstack_blank): Rearrange pointer math to avoid
4571 pointing past end of allocated memory; saber complains.
4572 obstack.h: Declare the external functions that we use.
4573 valarith.h: use <string.h>
4574 solib.c (solib_add): lint.
4576 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
4578 * main.c (initialize_main): Default info_verbose to off, now that
4579 symbol reading is fast.
4580 (quit_command): Avoid clobbering exec_bfd while quitting.
4582 * Initial BFD (binary file diddling library) merger:
4583 coffread.c: Change AOUTHDR to struct exe_hdr.
4585 core.c: initialize initialized data at compile time.
4586 (core_file_command): Move from coredep.c, convert to bfd.
4587 (xfer_core_file): Convert to bfd.
4588 exec.c (exec_file_command): use bfd routines.
4590 mips-tdep.c: Remove exec_file_command and friends.
4593 * coredep.c: (fetch_core_registers) Convert core_file_command to
4594 fetch_core_registers.
4595 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
4597 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
4598 (my_bfd_read): More bogosity, which I don't think we call.
4599 (program_name): Remove this atrocity asap!
4601 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
4604 values.c: allocate_repeat_value was not clearing the
4605 optimized_out field.
4606 (value_static_field): minor stylistic fix (wrong macro was used).
4607 valops.c (value_struct_elt_for_address): didn't work for C++
4610 * signame.c (_initialize_signame): Initialize signal names once.
4612 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
4613 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
4614 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
4616 * remote-eb.c: Support user-settable baud rates on the serial port.
4618 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
4620 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
4622 * tconfig/sun3os4: Remove warning about native assembler,
4623 since it also occurs in the xconfig file.
4625 * findvar.c (registers): Allocate some slop after `registers'
4626 to prevent stray accesses from trashing the next variable.
4628 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
4629 on the sun-3, by changing the #ifdef from `sun3' (which is not
4630 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
4631 vars, which happened to follow `registers' in the executable.
4633 * readline/history.c (history_search): Heed gcc-2's advice
4634 and parenthesize && inside ||).
4636 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
4637 tm-29k.c: Insert FSF copyright headers.
4639 * remote-eb.c: Better comments.
4641 * Makefile.dist: Update to 3.91.6.
4642 * TODO: note PREPARE_TO_STORE problem.
4644 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
4646 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
4648 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
4650 * infrun.c (wait_for_inferior, at end): Don't set up
4651 prev_* if the inferior no longer exists.
4653 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
4654 CANNOT_EXECUTE_STACK.
4655 valops.c (call_function): Use it.
4657 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
4659 * inferior.h (PC_IN_CALL_DUMMY): New macro.
4660 infrun.c (wait_for_inferior, 2 places): Use it.
4662 * values.c (value_being_returned): Only use
4663 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
4665 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
4666 right thing for remote-eb.c.
4668 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
4669 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
4671 * blockframe.c: Put get_frame_saved_regs inside #if !defined
4672 (FRAME_FIND_SAVED_REGS).
4674 * findvar.c ({fetch,store}_registers): Check for
4675 REMOTE_{FETCH_STORE}_REGISTER macro.
4677 * findvar.c (get_saved_register): Add argument lval and
4678 change meaning of argument addr.
4679 findvar.c: Change calls to get_saved_register to reflect
4680 new calling convention.
4681 valops.c (value_assign): Use get_saved_register instead of
4682 find_saved_register.
4684 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4686 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
4687 an (uninitialized) pointer to one. Use "&" when passing it
4690 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4692 * coffread.c (getfilename): Use DGUX x_offset and x_name if
4695 * coffread.c (symbol_file_command): Put semicolon after
4697 Put safe_to_init_tdesc_context in #if defined (TDESC).
4698 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
4699 coffread.c: #include <sys/stat.h>.
4700 (read_coff_symtab): Typo: in_source_files -> in_source_file.
4701 Add missing ')' in check for "lc%" and friends. Remove
4703 Declare read_one_sym() at top of file.
4704 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
4705 MC68WRMAGIC can have the same value without causing a duplicate
4708 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
4710 * Allow a Makefile to be built without building the
4711 tm and xm file links that screw up builds in subdirectories.
4712 This is done with `config.gdb none', then you can do things
4713 like `make gdb.tar.Z'.
4714 * tconfig/none: Config file for no target system
4715 * xconfig/none: Config file for no host system
4716 * config.gdb: If no TM or XM files are called out by the
4717 host or target file, don't make links for them.
4719 * cplus-dem.c: Add documentation.
4721 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
4722 simple error, so the user's gdb doesn't crash due to some object
4723 file problem (e.g. somebody is rebuilding the file out from under
4726 * printcmd.c (print_address_symbolic): demangle the symbol.
4728 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
4729 Motorola copyrights in it. Make "make gdb.tar.Z" work.
4730 (alldeps.mak): sort and uniq all results from this; duplicates
4731 hose gdb.tar.Z link building. Remove RCS files from
4732 tconfig and xconfig. Add config files for sun386. Add
4733 a few odd files to OTHERS and HFILES.
4735 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
4737 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
4738 Roll version number to 3.91.5. Make lint work in bindir.
4740 * README: Document cross-debugging and new file structure.
4742 * blockframe.c: Lint. Include "value.h" to declare read_register.
4743 (find_pc_partial_function): remove duplicate line.
4745 * command.h: Lint. Declare error_no_arg and dont_repeat.
4747 * tm-news.h: Remove inadvertently duplicated stuff.
4749 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
4750 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
4752 * config.gdb: Allow `config.gdb host target' form. Clean
4753 up previous change that printed bogus messages when you just said
4756 * core.c: #include "command.h" for lint.
4759 * main.c: Remove some casts of enums. Lint.
4766 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
4768 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
4769 read it from memory. This will allow us to save ptrace calls
4770 eventually. Changed caller single_step too.
4772 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
4773 that we aren't going to use, saving many ptrace calls, especially
4774 when watchpointing or single stepping. Use some #define's for
4776 (store_inferior_registers): Ditto.
4777 (core_file_command): Use some #define's for constants.
4779 * tm-sparc.h: Add #define's for some register numbers, so we
4780 can eliminate the use of random constants in sparc-xdep.c.
4782 * stack.c (frame_command, print_frame_info, up_command,
4783 down_command) Remove frame_changed, since it
4784 causes a bug and doesn't seem to do anything useful. In some
4785 places it was used as a flag, in others as a stack level (?).
4787 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
4788 default is to use the portable (vprintf) version rather than the
4790 * xm-news.h (MISSING_VPRINTF): Add.
4792 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
4794 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
4796 * Remove stuff that forces -Bstatic linking of gdb, and warnings
4797 about linking debugged programs -Bstatic in the sun?os4 config
4798 files in tconfig and xconfig subdirectories.
4800 * main.c (main): Remove unreached exit(0) now that we exit
4803 * Create TODO file for online bug list. There are too many
4804 "little" bugs to keep track of on paper.
4806 * Change Projects file to refer to bug-gdb@cygnus.com
4807 rather than kingdon@ai.
4809 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
4811 * Makefile.dist (VERSION): 3.91.4 now.
4813 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
4814 (condense_misc_bunches): Add sanity check that misc_count is
4815 the same as the number of symbols in the bunch.
4817 * coffread.c: rename init_misc_bunches. Pass an argument
4818 to condense_misc_bunches (a zero).
4820 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
4821 every time we are called; don't rely on our caller to do it.
4822 (add_file): Remove call to init_misc_bunches.
4824 * mipsread.c: Only warn, don't error, if unknown symbol types.
4825 This keeps an old gdb from falling on its face if it sees newly
4826 extended symbol info. Rename init_misc_bunches.
4828 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
4830 * Merge in changes from Per Bothner for DECstations and other
4831 MIPS stuff. The rest is Bothner speaking:
4833 The next message is a merger of Alessando Forin's mips port with
4834 mine. I've tried to use my good if biased judgment to get
4835 the best of both. It *does* need testing.
4837 Some of the changes are general, *not* mips-specific.
4840 Didn't believe in little-endian bit order.
4841 There are still inconsistencies about whether flags
4842 like BITS_BIG_ENDIAN are integer (#if ...) or
4843 boolean (#ifdef ...). I tried to paper over them.
4845 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
4846 Moved some misc_function code that was common to
4847 {dbx,coff,mips}read.c to symtab.c.
4848 In the process, I think I cleaned things up a bit.
4849 At the same time, moved obsavestring and obconcat to symtab.c.
4852 Removed obsolete condense_addl_misc_bunches (use
4853 condense_misc_bunches(1) instead).
4856 Needed to include <sys/dir>, at least on DECstations.
4858 valops.c, mips-tdep.c, tm-mips.h:
4859 Added PUSH_ARGUMENTS macro to support funny argument-pushing
4860 conventions (when STACK_ALIGN is insufficient).
4861 Needed on mips, where doubles need 8-byte alignment,
4862 but ints only need 4.
4865 Removed cruft that was not being used.
4866 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
4869 Print $ before register-names (I think that makes things a little
4871 Never print two instructions, even if one delays.
4872 Removed hex-disassemble set_cmd. (This is not mips-specific,
4873 so I think the argument is whether it is generally worthwhile or not.
4874 I'm inclined to think not, given how easy it is to
4875 convert between radixes in gdb.)
4878 This is basically Alessando's code.
4879 It doesn't use obstacks; I changed it to use obstacks
4880 in a few minor places where using malloc causes a
4881 memory leak. (Probably, more places could/should be changed.)
4882 I added record_misc_function where it was missing.
4883 In symbol_file_command and add_file_command, I tried
4884 to make the code consistent with more recent versions.
4885 Minor sylistic changes in parse_procedure.
4886 Make a .gdbinfo. psuedo-symbol point back to the real
4887 procedure symbol (using the isym field).
4890 This is basically from my port, but with a lot of details
4891 and a number of routines merged in from Alessando's version.
4892 I basically used my code "raw" backtrace (use heuristics
4893 from the actual code, rather than symbol table info) - though
4894 the idea is Alessandro's. I feel my code is a little cleaner
4895 here, particularly in being a little more flexible, such as being
4896 able to handle gcc-produced code (which it now can).
4897 It also doesn't do frame caching (which is not useful
4898 more recent gdb versions).
4899 I also used my code for push_/pop_dummy, more or less.
4900 I tried to incorporate AF's code for testing sigtramp
4901 while backtracing; I probably got it wrong.
4902 Added mips_print_register, which tries to scrunch as much
4903 information as possible on a screen...
4904 Removed the skip-prologue set_cmd. As with hex-disassemble (see
4905 under mips-pinsn.c), I don't see anything mips-specific here,
4906 and I don't see it being all that useful anyway.
4909 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
4910 Use more register names (rather than hard-cases numbers).
4912 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
4914 * Hack up 3.90.11 changes:
4916 * Makefile.dist (depend): parameterize $(GCC).
4917 Add solib.c and solib.o.
4918 (readline): Fix vpath for both absolute or relative SRCDIR.
4920 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
4921 Also, let the part I didn't understand at least compile so
4922 I can test the rest. FIXME.
4924 * dbxread.c: Fix thinko using strcmp.
4925 (init_psymbol_list): declare static.
4926 (partial_symbol_file_open): Comment cleanups better, avoid
4927 cleaning up the string table since the caller will do that.
4928 Move the stat for mod time into symbol_file_command, temporarily.
4929 (There should be a mod time for each symbol file, eventually,
4930 to control its rereading. FIXME.)
4932 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
4933 SunOS, which gives error for shared libs otherwise. (From
4934 Schaefer, probably FIXME needs work for portability.)
4936 * solib.c: Move #include "param.h" to work.
4937 Lowercase all the Uppercase Letters In the Messages.
4938 (find_solib): Clean up inferior_so_name for debug printouts.
4939 Allow no argument, to mean all shared libraries.
4941 * symmisc.c: include param.h to get CLEAR_SOLIB.
4943 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
4945 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
4946 to 3.90.11. ChangeLog entries below are from this.
4948 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
4952 * Makefile.dist (HFILES): Add tm-sunos.h.
4954 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4958 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
4960 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
4962 * sparc-opcode.h Added single-operand version of rett.
4964 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4966 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
4967 Put parens around gcc_p in expansion.
4969 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
4971 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
4973 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4975 * Changes for Sun shared libraries:
4976 blockframe.c (find_pc_partial_function): If a non-text symbol
4977 is found, set *address = pc - FUNCTION_START_OFFSET.
4978 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
4979 Disable breakpoints instead of giving an error.
4980 source.c (select_source_symtab): Initialize cs_pst.
4981 symmisc.c: Call CLEAR_SOLIB if defined.
4982 symtab.h: Make text{low,high} CORE_ADDR not int.
4983 (psymtab): New field addr.
4985 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
4986 (record_misc_function): Give correct type for N_DATA symbols.
4987 (condense_misc_bunches): do "misc_function_count = j" regardless
4989 Take code which is shared between symbol_file_command and
4990 add_file_command and put it into partial_symbol_file_{open,read}.
4991 Split add_file_command into add_file_command and add_file.
4992 Make psymtab_to_symtab read in the string table if the file
4994 Two new parameters to read_dbx_symtab and start_psymtab.
4995 tm-sunos.h: New file.
4997 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4999 * infcmd.c: Change cont_command to continue_command and "cont"
5002 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5004 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5006 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5008 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5009 size 1,2,4,8 rather than size < 8.
5011 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5012 as necessary, not just once.
5014 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5016 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5018 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5020 * tm-news.h: Add CALL_DUMMY_*.
5022 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5024 * config.gdb: In list_host, list_target, use ${i}, not $i.
5026 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5028 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5030 * sparc-opcode.h: Change all store floating-point state register
5031 instructions to have the right match & lose fields.
5033 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5035 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5037 config.gdb: If srcdir != ., create readline directory and
5038 copy a makefile into it.
5040 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5041 consistency with POSIX.
5043 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5044 when we exit its exp_valid_block.
5046 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5048 * Makefile.dist: Bump version to 3.91.3.
5050 * Clean up handling of breakpoint commands (somewhat).
5051 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5053 inferior.h: Add breakpoint_proceeded to inferior status struct
5054 and globals; save it and restore it.
5055 (clear_breakpoint_commands): Cleanup, remove old #define.
5057 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5058 (save_inferior_status, restore_inferior_status): handle it also.
5059 (proceed): Remove earlier code that set breakpoint_proceeded.
5060 It is now set only in clear_proceed_status.
5061 (clear_proceed_status): Cleanup, use bpstat_clear rather
5062 than clear_breakpoint_commands. No callers need the stop_bpstat
5063 between clear_proceed_status and proceed.
5065 infcmd.c: Add breakpoint_proceeded definition and comment.
5066 (cont_command, jump_command, signal_command): Move call to
5067 clear_proceed_status right next to call to proceed.
5069 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5070 caller's argument while running down the chain of breakpoints.
5071 Use new variable "breakpoint_proceeded" to determine when
5072 a command that it executes moves the inferior past the
5074 (bpstat_clear): Handle NULL argument.
5075 (bpstat_clear_actions): Avoid useless call to
5076 breakpoint_auto_delete.
5077 (delete_breakpoint): Clean up bpstat's that are pointing to
5078 the deleted breakpoint from the stop_bpstat chain.
5079 (breakpoint_auto_delete): Simplify.
5081 * Clean up handling of EOF, error on stdin, etc. This was
5082 prompted by a network problem that caused gdb to go into an
5083 infinite loop filling up its malloc'd memory.
5085 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5086 not clear_breakpoints_commands, which is now gone.
5087 (main): If command_loop returns (e.g. from EOF on stdin), do
5088 a quit_command (looping back to command_loop if quit_command
5089 doesn't really quit).
5090 (command_loop): check result from command_line_input and
5091 exit if it returns NULL, rather than passing the NULL to
5093 (gdb_readline): Free malloc'd result space before returning
5096 * utils.c (query): Handle C-d to mean "yes", just as if the
5097 input was not a terminal. Also avoid infinite loop if EOF
5098 occurs in mid-input-line before newline. This allows
5099 query to be used at EOF on stdin with reasonable results.
5101 * infrun.c (proceed): Set breakpoint_proceeded.
5103 * values.c (value_as_long): Avoid infinite recursion for enums.
5104 (_initialize_values): Fix typo in help msg (kingdon).
5106 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5107 RL_LIB for linking. This allows -lreadline for linking
5108 and nothing for dependencies, once readline is a real library.
5110 * config.gdb: Jim Kingdon: give useful error message if the
5111 host or target type is not recognized.
5113 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5114 it just defines it. Dumb, but deal with it.
5116 * Jim Kingdon suggests:
5117 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5119 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5121 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5123 * Clean up Bothner's changes.
5125 * blockframe.c (clear_pc_function_cache): New function.
5126 * blockframe.c: remake cache_pc_function_* static.
5127 * dbxread.c (symbol_file_command): remove references to
5128 cache_pc_function_* variables.
5129 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5130 * printcmd.c: Avoid kludging a global variable (addressprint)
5131 to avoid printing the address of a string twice. Instead,
5132 pass the format letter 's' down low enough that it can be seen
5133 to avoid this problem.
5134 (print_formatted): Pass format arg to value_print.
5135 (restore_addressprint): Remove function.
5136 (do_examine): Avoid hacking addressprint, cleanups and such.
5137 (print_frame_args): Add a comment to a Bothner change.
5138 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5139 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5140 to wipe out the values cached in blockframe.c.
5141 * symtab.c (find_method): Add comment saying how big you must
5142 allocate to be "big enough". Per being terse again.
5143 * valprint.c (val_print): Handle format letter "s" to print
5144 strings without addresses. Add comment to vtbl printing code
5145 which casts with wild abandon. Rearrange reference-printing
5147 @0xaddr: value (print w/addressprint)
5148 value (print w/~addressprint)
5149 @0xaddr (parameter lists w/addressprint)
5150 or nothing (parameter lists w/o addressprint)
5152 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5154 * Merge more changes from Per Bothner:
5156 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5157 annoying) that I tried to improve it. Here are my suggestions.
5159 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5162 Do automatic de-reference when taking the address of a reference.
5164 Don't deref_ref when printing parameter lists.
5166 More attempts at treating refernences properly.
5168 In val_print, if deref_ref==0, don't print dangling " = ".
5170 Add COERCE_REF macro, which de-references an REF.
5172 * Merge changes from Per Bothner:
5174 * Fixed (Sony news)-specific configuration problems.
5175 * Fixed other problems with using vanilla pcc and libc (enum problems;
5176 assumption that vsprintf exists).
5177 * Some major speed-ups (finc_pc_partial_function now caches a match;
5178 parsing avoids duplicate symbol_lookup calls).
5179 * Changed handling of baseclasses (no longer use baseclasses field
5180 of struct type, use the first n_baseclasses fields instead).
5181 * Various minor changes/fixes, most C++-related.
5184 Cache the most previous match from find_pc_partial_function.
5185 (Save both low and high ends of matching function's pc range.)
5186 This speeds up the loop of infrun.c:wait_for_inferior quite
5187 a bit, and makes step/next commands much zippier.
5189 Added an enum->int cast (otherwise, some compilers barf).
5191 No longer set baseclass offset to 0, since multiple
5192 inheritance now mostly works.
5193 Added a number of casts, to shut up compiler warnings
5194 (after stabs where made enums, not ints).
5195 When discarding a symbol table (in symbol_file_command),
5196 must clear the cache introduced in blockframe.c.
5197 Don't convert $vtbl_ptr_type to vtbl any more.
5198 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5199 Mask off sign bit emitted by g++ for virtual table offset.
5200 Set voffset to -1 (not 1) for static member functions.
5202 Changed parsing/lexing of names to avoid doing symbol lookup twice
5203 (once when lexing to determine symbol class, once for real).
5204 Now only call symbol_lookup once. Fields of 'this' win especially big.
5206 Subpress printing addr twice in the case of 'x/s addr'.
5208 lookup_basetype_type is no longer used.
5209 Add find_methods as recursive helper function to decode_line_1.
5210 This allows multiple inheritance to work.
5211 Also, once one or more matches has been found, do not look in
5212 base-classes. (Baseclass methods would be overridden, anyway.)
5214 Removed baseclasses array in struct type.
5215 Instead of using baseclasses[i], use fields[i-1].
5216 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5217 Changed sign convention of voffset (previous was inconsistent).
5219 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5221 Used to assume existence of vsprintf. Re-written to not need it
5222 if HAVE_VPRINTF is undefined.
5224 typecmp was too pessimistic. Made it less so.
5226 Don't print space after address.
5227 If vtable points to a misc symbol (with 0 offset), print it,
5228 since that indicates the actual class of the object.
5229 Changed ype_print_derivation_info to use new inheritance
5230 scheme (without baseclasses vector).
5232 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5233 Also, changes needed because TYPE_BASECLASSES were removed.
5235 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5237 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5240 If there is no path set, and the symbols don't indicate what directory
5241 a file was compiled in, look in the current directory. But either
5242 a path or a known compilation directory will prevent this.
5245 Three independent bug fixes:
5246 * Remove the #if 0 block that breaks some stuff.
5247 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5248 adapt gdb to either SunOS 4.0.* or 4.1.
5249 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5252 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5255 (type_print) Demangle the name being printed.
5256 (type_print_base) Handle botched demangling without coredump (tiemann).
5259 (check_stub_method): Document routine.
5260 (tiemann) fix bug for no-arg functions
5261 Avoid clobbering beyond end of malloc'd storage.
5262 Terminate the argument list properly.
5264 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5266 * Changes merged by John Gilmore:
5269 In breakpoint_1, use new print_address_symbolic instead
5270 of find_pc_partial_function. (This forces use of assembler-level
5271 addresses, and avoids misleading non-mangled source-level names.)
5273 Generalize ansi argument such that -1 means skip arglist totally.
5274 Removed global variable print_ansi_qualifiers (which made
5275 code non-reentrant), in favor of extra explicit arguments
5276 to internal routines.
5278 Add new helper function print_address_symbolic.
5279 Use find_pc_misc_function instead of find_pc_partial_function
5280 (since we want assembler-level symbols here).
5282 Print unknown function as just "f (...)", not "f (...) (...)".
5283 Use new fputs_demangled explicitly.
5285 Fixed a typing violation (problem: value.h cannot be imported
5286 without renaming many variable in this file).
5287 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5288 decode_line_1: Moved forward some never-reached code.
5289 Made decode_line_2 skip function prologues correctly.
5291 fputs_filtered should not demangle by default.
5292 Add new fputs_demangled to demangle on demand..
5294 Change value_struct_elt to use value_primitive_field (using recursive
5295 utility function search_struct_field). This allows foo.bar to work
5296 for multiple inheritance (so far only for data fields).
5297 Change check_field in the same way (recursive helper function
5298 to support multiple inheritance).
5299 (Note: there are more of these problems that I haven't fixed.
5300 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5301 value_of_this: 'this' symbol name is now just "this", note "$this".
5303 Don't print static members.
5304 Avoid printing "members of <type>" if there are none.
5305 Simplified type_print_derivation_info by merging duplicate code.
5306 Remove useless blank lines in type_print_base (ptype command).
5308 Added declaration of new routine value_primitive_field.
5310 Added value_primitive_field which is generalized version of
5311 value_field that can handle multiple inheritance (non-zero offsets etc).
5312 Re-implemented value_field to call value_primitive_field.
5314 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
5316 * infcmd.c -- insert else to avoid 'delete env' coredump when you
5317 delete the whole environment. Karl Berry reported the bug.
5318 * source.c - fix openp to avoid //'s in filenames, which
5319 trigger an Emacs bug causing it to not be able to find files
5320 when running gdb in a window.
5321 * dbxread.c - zap the #if 0 that botches the add-file code.
5322 It seems to work a lot better without all the code commented out.
5324 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
5326 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
5329 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
5331 * Makefile - added a ${CFLAGS} to a couple of entries,
5332 added remote-sa.sparc.c
5333 * added remote.sa-sparc.c, a modification of remote.c
5334 which conducts a dialog directly with the SparcStation prom.
5335 * breakpoint.c, infrun.c, sparcdep.c added
5336 remote_insert_breakpoint(), and remote_remove_breakpoint()
5337 to breakpoint.c instead of directly writing breakpoint instructions.
5338 * sparcdep.c on remote_debugging,there is no need
5339 to remove signle step breakpoint instructions.
5340 * main.c added "-epoch" flag and "int epoch_interface" to main.c
5342 * printcmd.c - epoch interface sends lisp expressions to open up
5343 epoch windows on inspection.
5344 * valprint.c - added arrayprint, and addressprint and made adding
5345 format controls easier
5346 * wait.h added a couple of undef's because we were getting
5347 complaints about WSTOPSIG and WTERMSIG begin redefined.
5350 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
5352 * symtab.c (decode_line_1): Add support for handling method stubs
5353 in the type information.
5355 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
5357 * values.c (baseclass_addr): Run loop from INDEX+1 to
5358 N_BASECLASSES; otherwise, we can still get into a loop.
5359 @@ This should be restructured to use a cleaner search strategy.
5361 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
5363 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
5364 abbreviation "Tt" for tags which have the same name as their
5367 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
5369 * symtab.c (list_symbols): add ability to set breakpoints on all
5370 the functions which match a particular regular expression.
5372 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
5374 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
5375 should print ANSI qualifiers (such as `const' and `volatile').
5376 All callers changed to call with ANSI == 1, except from
5377 `check_method_stub', which uses old-style syntax.
5379 * symseg.h (struct fn_field): Remove unneccessary `args' field.
5380 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
5382 * values.c (check_stub_method): New function.
5384 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
5386 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
5387 * valprint (type_print_base): Ditto.
5389 * symtab.c (gdb_mangle_typename): New function.
5391 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
5393 * breakpoint.c (catch_command): New function. Provides a
5394 mechanism to set breakpoints based on catch clauses.
5395 (disable_catch): Similar, but disables breakpoints on catch
5397 (delete_catch): Similar, but deleted breakpoints on catch clauses.
5399 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
5401 * blockframe.c (blockvector_for_pc): New function.
5402 * blockframe.c (block_for_pc): Changed to call
5403 `blockvector_for_pc' and get the block itself.
5405 * stack.c (catch_info): New function. Prints info about
5406 exceptions which can be caught in the current frame.
5407 * stack.c (print_frame_label_vars): New function. Similar to
5408 `print_frame_local_vars'.
5409 * stack.c (print_block_frame_labels): Prints out labels that are
5410 defined in this frame. These labels are exceptions that can be
5413 * dbxread.c: Updated to handle N_CATCH symtab types.
5415 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
5417 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
5418 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
5419 when printing the type.
5421 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
5423 * valprint.c (val_print): Use `baseclass_addr' to access the
5424 baseclasses pointed to via the derived class object at VALADDR.
5426 * values.c (baseclass_addr): New function. Casts derived pointers
5427 to baseclass pointers taking virtual baseclasses and multiple
5428 inheritance into account.
5430 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5434 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5436 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
5437 exp_valid_block field correctly.
5439 * infrun.c (wait_for_inferior): When checking "don't even think
5440 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
5441 also check step_resume_breakpoint.
5442 Insert breakpoints and continue (not step) if
5443 step_resume_break_address != NULL, even if another_trap.
5444 If trap_expected and we enter sigtramp, then set up a
5446 If trap_expected is set when we hit the step_resume_break,
5448 When calling resume and trap_expected says tell resume to step
5449 (2 places), also check step_resume_break_address.
5451 * infrun.c (wait_for_inferior): Don't set
5452 prev_{pc,sp,func_{start,name}} before calling wait ().
5453 Do set them after exiting loop.
5454 Move their declarations outside functions.
5455 (start_inferior): Initialize them.
5457 Thu May 3 00:15:11 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5459 * infrun.c (wait_for_inferior, after check for trap_expected > 1):
5460 Restore old code which distinguishes between trap_expected and
5461 running_in_shell, just make the latter take any non-TRAP signal,
5464 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
5466 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.
5467 xconfig/3b1 (CC,PINSN_CC): Define.
5469 * xconfig/altos, altos-dep.c: Rename altos-dep.c to altos-xdep.c.
5473 * breakpoint.c (bpstat_stop_status),
5474 infrun.c (wait_for_inferior) [SHIFT_INST_REGS]: New code.
5476 * param.h, tm-88k.h: Define ADDR_BITS_*.
5477 infcmd.c (jump_command, read_pc), infrun.c (wait_for_inferior),
5478 printcmd.c (do_one_display): Use them.
5480 * utils.c: Split #ifdef USG into a USG_UTILS and a QUEUE_MISSING.
5481 xm-88k.h: Define USG_UTILS.
5483 Wed May 2 00:05:33 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
