1 Fri Jan 21 09:23:33 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2
3 * xcoffread.c (xcoff_symfile_read): Make second parameter a
4 struct section_offsets *, not a (nonexistent) struct section_offset *.
5
6 * xcoffread.c (read_xcoff_symtab): Make main_aux just a union
7 internal_xcoff_symtab, not an array of one of them. Change lots of
8 "main_aux" to "&main_aux" and so on.
9
10 * coffread.c, xcoffread.c: Include <coff/internal.h>
11 before "symfile.h".
12
13 Thu Jan 20 17:30:55 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
14
15 * coffread.c (coff_getfilename): Make it not static.
16
17 * xcoffread.c (read_xcoff_symtab): complain() not abort().
18
19 * xcoffread.c (struct coff_symbol): Rename c_nsyms to c_naux (removes
20 a completely gratuitous difference between xcoffread.c and coffread.c).
21
22 Wed Jan 19 15:09:44 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
23
24 * infrun.c (wait_for_inferior): Don't set frame for
25 step_resume_breakpoint for IN_SIGTRAMP cases.
26
27 * infrun.c (wait_for_inferior), breakpoint.h (struct bpstat_what),
28 breakpoint.c (bpstat_what): Move step_resume from its own field of
29 the struct bpstat_what into the main_action. Make it override
30 other breakpoints. This is a conservative change in the sense
31 that before the step resume breakpoint was a breakpoint.c
32 breakpoint, hitting the step resume breakpoint overrode even
33 calling bpstat_stop_status.
34
35 Wed Jan 19 12:40:25 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
36
37 * infrun.c (normal_stop): Set stop_pc after popping the dummy frame
38 in case execution was stopped in the called function.
39 * stack.c (print_frame_info, frame_info): If backtracing through
40 a call dummy, handle the starting source line number on a line
41 boundary like backtracing through sigtramp.
42 * sparc-tdep.c (sparc_frame_find_saved_regs): Get frame address
43 for call dummy frame right. Remove old test for dummy frame,
44 it has been unused at least since gdb-3.5.
45 * sparc-tdep.c (sparc_push_dummy_frame): Set return address register
46 of the dummy frame.
47
48 Tue Jan 18 16:16:35 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
49
50 * infcmd.c (signal_command): Accept 0 as legitimate signal number.
51
52 Tue Jan 18 14:09:25 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
53
54 * infrun.c (signals_info), target.c (target_signal_from_name):
55 Use ugly casts to avoid enumvar < enumvar or enumvar++.
56
57 Mon Jan 17 22:00:15 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
58
59 * ser-unix.c (hardwire_noflush_set_tty_state): Don't muck with ICANON.
60 * inflow.c (terminal_ours_1): When discussing how to deal with the
61 tty state, make note of query() as well as readline.
62
63 * infrun.c (_initialize_infrun): Add TARGET_SIGNAL_POLL to list of
64 signals for which stop and print are cleared by default.
65
66 Mon Jan 17 20:00:51 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
67
68 * config/pa/tm-hppa.h (unwind_table_entry): Use one of the
69 reserved fields to hold a stub unwind entry type. Fix typo.
70 (stub_unwind_entry): New structure for raw stub unwind entries.
71 (stub_unwind_types): The types of stubs we may encounter.
72 (UNWIND_ENTRY_SIZE, STUB_UNWIND_ENTRY_SIZE): New defines.

74 by linker stub unwind descriptors.
75 (frameless_function_invocation): Likewise.
76 (frame_chain_valid): Likewise.
77 * paread.c (compare_unwind_entries): New function for sorting
78 unwind table entries.
79 (read_unwind_info): Rewrite to remove dependency on host endianness.
80 Read in data from the $UNWIND_END$ subspace which contains linker
81 stub unwind descriptors. Merge that data into the basic unwind
82 table.
83
84 * hppab-nat.c (_initialize_kernel_u_addr): Delete unwanted functions.
85
86 Mon Jan 17 22:00:15 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
87
88 * xcoffread.c (read_xcoff_symtab, case C_FILE): Accept the name
89 from either the symbol name or the auxent.
90 * coffread.c, symfile.h (coff_getfilename): Renamed from getfilename,
91 no longer static.
92
93 Mon Jan 17 13:35:01 1994 Fred Fish (fnf@cygnus.com)
94
95 * Makefile.in (ALLPARAM): Change irix5.h to nm-irix5.h.
96
97 Mon Jan 17 12:35:42 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
98
99 * README: Update notes for alpha port.
100
101 Mon Jan 17 11:15:57 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
102
103 * i960-tdep.c (i960_fault_to_signal): Return TARGET_SIGNAL_ILL
104 for operation fault, constraint fault, and type fault.
105
106 Sun Jan 16 12:46:01 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
107
108 * Makefile.in (init.c): Add comment explaining formatting conventions.
109
110 * c-exp.y (parse_number): Assign to temporary between the right
111 shifts, to work around a bug in the SCO compiler.
112
113 * Makefile.in (ALLCONFIG, ALLPARAM, ALLDEPFILES, HFILES_NO_SRCDIR):
114 Add various files which were added to GDB recently.
115
116 * xcoffread.c (process_xcoff_symbol): Only change 'V' to 'S' if not
117 within_function.
118
119 * Makefile.in: Add mostlyclean target.
120
121 Sat Jan 15 10:20:13 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
122
123 * Version 4.11.4.
124
125 Sat Jan 15 18:27:34 1994 Per Bothner (bothner@kalessin.cygnus.com)
126
127 * main.c (show_commands): Make return type of extern
128 history_get be HIST_ENTRY, rather than struct _hist_entry.
129 (The latter loses with the upcoming merged readline.)
130
131 Sat Jan 15 10:20:13 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
132
133 * minsyms.c (prim_record_minimal_symbol_and_info): Make tempstring
134 const char *, not char *.
135
136 * symtab.h (struct symbol): Make section short, not unsigned short.
137
138 * symtab.c (lookup_symbol): Add comment about QUIT here.
139
140 * utils.c (fputs_unfiltered): Call fputs, not fputs_maybe_filtered.
141
142 * c-exp.y (parse_number): Check for overflow regardless of range
143 checking. Fix overflow check to use unsigned LONGEST, not
144 unsigned int.
145
146 * c-exp.y (parse_number): Make it so that integer constants are
147 builtin_type_long_long if builtin_type_long isn't big enough or if
148 an "LL" suffix is used. Properly handle "UL" or "LU" suffixes.
149
150 * c-typeprint.c (c_type_print_varspec_suffix, case TYPE_CODE_FUNC):
151 Print our "()" first, then recurse for the target type.
152
153 Fri Jan 14 21:55:39 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
154
155 * remote-udi.c (udi_create_inferior): Quote empty execfile argument.
156
157 * gdbserver/low-lynx.c: Include <sys/wait.h> not "/usr/include/wait.h".
158
159 Fri Jan 14 14:17:06 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
160
161 * utils.c (request_quit): Re-establish signal handler regardless
162 of USG.
163
164 * config/mips/xm-irix4.h: Define HAVE_TERMIOS.
165
166 Fri Jan 14 21:55:39 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
167
168 * i960-tdep.c: Include target.h.
169
170 Fri Jan 14 17:12:28 1994 Stan Shebs (shebs@andros.cygnus.com)
171
172 * lynx-nat.c (sys/wait.h): Don't use absolute pathname.
173
174 Fri Jan 14 11:06:10 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
175
176 * lynx-nat.c (child_wait): Fix thinkos in struct target_waitstatus
177 changes (status -> ourstatus; declare status, etc.).
178 * config/nm-lynx.h: Fix child_wait prototype and include target.h.
179
180 Fri Jan 14 14:17:06 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
181
182 * Makefile.in (ALLPARAM): Add config/nm-lynx.h.
183
184 Fri Jan 14 11:49:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
185
186 * remote-mips.c (mips_request, mips_wait): Correct prototypes.
187
188 Fri Jan 14 11:37:17 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
189
190 * config/i386/xm-linux.h: Define HAVE_TERMIOS.
191
192 Fri Jan 14 01:04:36 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
193
194 * config/alpha/tm-alpha.h (CALL_DUMMY): Improve comment.
195
196 Thu Jan 13 10:32:38 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
197
198 * remote-vx.c (vx_wait): Only call i960_fault_to_signal if I80960
199 is defined. Otherwise just report TARGET_SIGNAL_UNKNOWN.
200
201 * mips-tdep.c (mips_push_arguments): Byteswap struct_addr before
202 writing it.
203
204 Add search to target vector (#if 0'd until after 4.12):
205 * target.h (to_search, target_search): Add.
206 * gdbcore.h, core.c (generic_search): Add.
207 * remote.c (remote_search): Add.
208 * a29k-tdep.c (init_frame_info): Use target_search to find traceback
209 tag.
210
211 * printcmd.c (print_address_symbolic): If set print fast-symbolic-addr
212 is on, call find_pc_function rather than relying just on the minimal
213 symbols (probably only matters for symbol readers which don't put
214 statics in the minimal symbols, but changing this strikes me as
215 not conservative enough).
216 Initialize name_location in all cases.
217 If no symbol and no msymbol, don't print anything symbolic.
218
219 * a29k-tdep.c (push_dummy_frame): Add comment about saving lr0.
220
221 Wed Jan 12 20:53:16 1994 John Gilmore (gnu@cygnus.com)
222
223 * printcmd.c (print_address_symbolic): Make it search the
224 symtabs for variables as well as functions. Add `set print
225 fast-symbolic-addr' and default it to fast (the old way).
226 Print line numbers for data items as well as functions.
227
228 * symtab.c (find_addr_symbol): Return the symtab and the symbol
229 address, if a symbol is found (take two more args pointing to
230 where to store these results).
231
232 * symtab.h (find_addr_symbol): Add prototype.
233
234 Wed Jan 12 19:32:11 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
235
236 * objfiles.h: Fix comments to reflect the fact that the phrase
237 "top of stack" always refers to where the pushing and popping takes
238 place, regardless of whether it is at the highest or lowest address.
239
240 Wed Jan 12 13:23:37 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
241
242 * mdebugread.c (parse_symbol): Do not set TYPE_TAG_NAME for
243 compiler generated tag names.
244 * mdebugread.c (parse_type): Handle cross references to qualified
245 aggregate types.
246 * valops.c (value_struct_elt): Improve error message if the
247 address of a method is requested from an object instance.
248 * valops.c (search_struct_method): Make name_matched non-static
249 to get it initialized correctly.
250 * config/i386/nm-i386sco.h (CANNOT_STORE_REGISTER): Define to
251 exclude segment register which are not writable on newer SCO versions.
252
253 Wed Jan 12 14:44:45 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
254
255 * go32-xdep.c: Remove unused function uerror.
256 (sigsetmask): Declare return type. Declare argument (to match the
257 way it is called). Explicitly return 0.
258
259 Wed Jan 12 01:44:25 1994 John Gilmore (gnu@cygnus.com)
260
261 * symtab.h (struct symbol, general_symbol_info, minimal_symbol,
262 partial_symbol): Shrink the storage sizes of symbols, by making
263 enums into 1-byte bitfields when compiled __GNUC__, moving all the
264 enums and small ints to the end of each struct to improve
265 alignment, and switching the section number from int to unsigned
266 short.
267
268 Wed Jan 12 00:16:26 1994 John Gilmore (gnu@cygnus.com)
269
270 * symtab.c (find_addr_symbol): New routine that will find the nearest
271 symbol associated with an address. It does so by exhaustive
272 search of the symtabs, so it's slow but complete.
273
274 Tue Jan 11 23:57:30 1994 John Gilmore (gnu@cygnus.com)
275
276 * coffread.c (read_coff_symtab): Set PC bounds of _globals_ symtab
277 to [0,0] rather than [0, end of first source file]. This avoids
278 problems with other parts of GDB looking for linetables in the
279 _globals_ symtab. Eliminate variables num_object_files and
280 first_object_file_end.
281
282 Tue Jan 11 00:53:46 1994 John Gilmore (gnu@cygnus.com)
283
284 * a29k-tdep.c (init_frame_info): Cast null arg to examine_tag.
285 (pop_frame): Restore PC2 and LR0 from dummy frames.
286 (push_dummy_frame): Save PC2 and LR0 into dummy frames.
287 (setup_arbitrary_frame): Handle 3 args and set up real frames.
288 * config/a29k/tm-a29k.h (FRAME_NUM_ARGS): Update comments.
289 (DUMMY_FRAME_RSIZE): Add 2 longwords for PC2 and LR0.
290 (SETUP_ARBITRARY_FRAME): Define.
291
292 Tue Jan 11 06:59:10 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
293
294 * infrun.c, config/mips/tm-irix5.h: Remove #if 0'd AT_FUNCTION_START.
295
296 Tue Jan 11 14:27:03 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
297
298 * remote-udi.c (udi_resume): Correct prototype.
299
300 Tue Jan 11 11:10:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
301
302 * config/pa/tm-hppa.h (FRAME_FIND_SAVED_REGS): Call
303 hppa_frame_find_saved_regs.
304 * hppa-tdep.c (dig_fp_from_stack): Delete function.
305 (prologue_inst_adjust_sp): New function.
306 (is_branch, inst_saves_gr, inst_saves_fr): New functions.
307 (skip_prologue): Completely rewrite to use unwind information.
308 (hppa_frame_find_saved_regs): Likewise.
309
310 Tue Jan 11 06:59:10 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
311
312 * remote-mips.c (mips_wait): Use new function mips_signal_from_protocol
313 to convert a signal number with appropriate bounds checking.
314
315 * remote-mips.c (mips_wait): Fix typos (0x177 -> 0177, 0x377 -> 0377).
316
317 Tue Jan 11 00:53:46 1994 John Gilmore (gnu@cygnus.com)
318
319 * stack.c (frame_info): If FRAME_FIND_SAVED_REGS isn't defined,
320 print a newline to end the display anyway.
321
322 * sparc-tdep.c (sparc_pop_frame): Pop the fsr and csr (float and
323 coprocessor status regs) when popping a frame. This fixes
324 float exceptions that occur after calling inferior functions.
325
326 * sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
327 Read and write the fsr (float status register) to/from the child
328 process along with the float regs. Remove Peter Schauer's change
329 of May 24 '93, which has higher overhead and doesn't solve the
330 real problem (which was that FSR wasn't being set).
331
332 Mon Jan 10 23:16:42 1994 John Gilmore (gnu@cygnus.com)
333
334 * a29k-tdep.c (examine_prologue): Don't worry if the ASGEQ
335 stack overflow check isn't right after the register stack
336 adjustment instruction. Metaware R2.3u compiler moves other
337 things in front of it. This fix isn't perfect but is what's
338 running.
339
340 Mon Jan 10 20:08:23 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
341
342 * c-valprint.c (c_val_print): Treat TYPE_CODE_RANGE like TYPE_CODE_INT.
343
344 * config/alpha/alpha-netware.mt: Rename to alpha-nw.mt for 14
345 character filenames.
346 * configure.in: Change accordingly.
347
348 Mon Jan 10 15:48:36 1994 Tom Lord (lord@rtl.cygnus.com)
349
350 * m68k-stub.c, sparc-stub.c: removed spurious introduction of
351 _filtered io routines from these two files.
352
353 Fri Jan 7 12:42:45 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
354
355 * config/i386/tm-i386v.h, config/m68k/tm-m68k.h, config/mips/tm-mips.h,
356 config/vax/tm-vax.h (CALL_DUMMY_BREAKPOINT_OFFSET): Define.
357 * mdebugread.c (parse_symbol): Handle enum sh.type produced by
358 DEC c89.
359 * mdebugread.c (add_line): Handle zero linenos produced by DEC c89.
360
361 Fri Jan 7 12:55:25 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
362
363 * utils.c (print_sys_errmsg): Call gdb_flush (gdb_stdout) before
364 printing to gdb_stderr.
365
366 * remote-udi.c (udi_kill): Don't close the connection, just set
367 inferior_pid to zero.
368 (udi_mourn): Call remove_breakpoints.
369
370 * remote-udi.c: Remove obsolete need_artificial_traps comment.
371
372 * i386b-nat.c (sregmap): If sEAX, etc., not defined, use tEAX, etc.
373
374 Thu Jan 6 07:17:53 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
375
376 * symtab.c (lookup_symbol): Don't try adding .c to the name.
377
378 * remote-bug.c: At the start of each section, reset srec_frame
379 back to 160.
380
381 * target.h: Add TARGET_WAITKIND_LOADED and TARGET_WAITKIND_SPURIOUS.
382 * target.c (store_waitstatus): Add CHILD_SPECIAL_WAITSTATUS hook.
383 * infrun.c (wait_for_inferior): Replace SIGTRAP_STOP_AFTER_LOAD with
384 code which looks for those two waitkinds. Use switch statement.
385 * config/rs6000/tm-rs6000.h: Replace SIGTRAP_STOP_AFTER_LOAD with
386 CHILD_SPECIAL_WAITSTATUS.
387
388 * procfs.c (procfs_wait): Fix argument name to match 4 Jan changes.
389 * Move target_signal_from_host, target_signal_to_host, and
390 store_waitstatus from inftarg.c to target.c. procfs needs them.
391 * target.c: Include "wait.h" and <signal.h>.
392 * target.h, infrun.c (proceed), proceed callers: Pass new code
393 TARGET_SIGNAL_DEFAULT instead of -1. This avoids problems with
394 enums being treated as unsigned and is cleaner.
395 * infrun.c (signals_info): Don't print TARGET_SIGNAL_DEFAULT or
396 TARGET_SIGNAL_0.
397 * infcmd.c (signal_command), infrun.c (signals_info):
398 Don't allow user to specify numeric equivalent of
399 TARGET_SIGNAL_DEFAULT.
400
401 Tue Jan 4 15:34:36 1994 Stu Grossman (grossman@cygnus.com)
402
403 * config/alpha/alpha-netware.mt: New target support for Alpha
404 running Netware.
405 * configure.in: Add alpha-*-netware* target.
406
407 Tue Jan 4 14:51:35 1994 Stan Shebs (shebs@andros.cygnus.com)
408
409 * remote-mips.c (mips_wait): Fix ref to TARGET_WAITKIND_STOPPED.
410
411 Tue Jan 4 09:47:14 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
412
413 * target.h: Add enum target_waitkind, enum target_signal, and
414 struct target_waitstatus. Change status argument to target_wait to
415 be struct target_waitstatus * instead of int *.
416 * target.h, infrun.c, all targets: Change type of signal arguments
417 to resume(), proceed(), and target_resume() from int to enum
418 target_signal.
419 * All targets (*_wait, *_resume): Change accordingly.
420 * infcmd.c (program_info, signal_command), throughout infrun.c,
421 * fork-child.c, solib.c, hppa-tdep.c, osfsolib.c: Use this stuff.
422 * convex-xdep.c, convex-tdep.c: Add FIXME's (getting the Convex
423 signal code stuff right with the new signals would be non-trivial).
424 * inferior.h (stop_signal): Make it enum target_signal not int.
425 * target.c, target.h (target_signal_to_string, target_signal_to_name,
426 target_signal_from_name): New functions.
427 * inftarg.c, target.h (target_signal_to_host, target_signal_from_host,
428 store_waitstatus): New functions.
429 * procfs.c (procfs_notice_signals): Use them.
430 * i960-tdep.c (i960_fault_to_signal): New function, to replace
