1 Fri Jan 21 17:49:28 1994 Stu Grossman (grossman at cygnus.com)
3 * lynx-nat.c: Add Sparc support.

12 * rs6000-pinsn.c: Use the new disassembler in the opcodes
13 directory. Old code was discarded, since the new opcode table has

23 if N_SO_ADDRESS_MAYBE_MISSING is defined.
24 * config/sparc/tm-sun4sol2.h: Define it.
26 Thu Jan 20 15:04:24 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
28 * printcmd.c (print_address_symbolic): Unconditionally use msymbol
29 if we did not find a symbol.
31 Fri Jan 21 08:20:18 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
33 * infptrace.c (child_xfer_memory): Only use if CHILD_XFER_MEMORY
36 * hppab-nat.c (call_ptrace): Delete redundant function.
37 (kill_inferior, attach, detach, child_resume): Likewise.
38 (child_xfer_memory): Likewise.
40 * hppah-nat.c (call_ptrace): Delete redundant function.
41 (kill_inferior, attach, detach, child_resume): Likewise.
43 * config/pa/hppabsd.mh (NATDEPFILES): Add infptrace.o.
45 * config/pa/hppahpux.mh (NATDEPFILES): Add infptrace.o.
47 * config/pa/nm-hppab.h (FETCH_INFERIOR_REGISTERS): Define.
49 * config/pa/nm-hppah.h (FETCH_INFERIOR_REGISTERS): define.
50 (CHILD_XFER_MEMORY): Define.
51 (PT_*): Define so that generic infptrace.c code can be used.
53 Fri Jan 21 09:23:33 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
55 * xcoffread.c (xcoff_symfile_read): Make second parameter a
56 struct section_offsets *, not a (nonexistent) struct section_offset *.
58 * xcoffread.c (read_xcoff_symtab): Make main_aux just a union
59 internal_xcoff_symtab, not an array of one of them. Change lots of
60 "main_aux" to "&main_aux" and so on.
62 * coffread.c, xcoffread.c: Include <coff/internal.h>

67 * coffread.c (coff_getfilename): Make it not static.
69 * xcoffread.c (read_xcoff_symtab): complain() not abort().
71 * xcoffread.c (struct coff_symbol): Rename c_nsyms to c_naux (removes
72 a completely gratuitous difference between xcoffread.c and coffread.c).
74 Wed Jan 19 15:09:44 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
76 * infrun.c (wait_for_inferior): Don't set frame for
77 step_resume_breakpoint for IN_SIGTRAMP cases.
79 * infrun.c (wait_for_inferior), breakpoint.h (struct bpstat_what),
80 breakpoint.c (bpstat_what): Move step_resume from its own field of
81 the struct bpstat_what into the main_action. Make it override
82 other breakpoints. This is a conservative change in the sense
83 that before the step resume breakpoint was a breakpoint.c
84 breakpoint, hitting the step resume breakpoint overrode even
85 calling bpstat_stop_status.
87 Wed Jan 19 12:40:25 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
89 * infrun.c (normal_stop): Set stop_pc after popping the dummy frame
90 in case execution was stopped in the called function.
91 * stack.c (print_frame_info, frame_info): If backtracing through

95 for call dummy frame right. Remove old test for dummy frame,
96 it has been unused at least since gdb-3.5.
97 * sparc-tdep.c (sparc_push_dummy_frame): Set return address register
100 Tue Jan 18 16:16:35 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
102 * infcmd.c (signal_command): Accept 0 as legitimate signal number.
104 Tue Jan 18 14:09:25 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
106 * infrun.c (signals_info), target.c (target_signal_from_name):
107 Use ugly casts to avoid enumvar < enumvar or enumvar++.
109 Mon Jan 17 22:00:15 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
111 * ser-unix.c (hardwire_noflush_set_tty_state): Don't muck with ICANON.

120 * config/pa/tm-hppa.h (unwind_table_entry): Use one of the
121 reserved fields to hold a stub unwind entry type. Fix typo.
122 (stub_unwind_entry): New structure for raw stub unwind entries.
123 (stub_unwind_types): The types of stubs we may encounter.
124 (UNWIND_ENTRY_SIZE, STUB_UNWIND_ENTRY_SIZE): New defines.
125 * hppa-tdep.c (rp_saved): Use additional information provided
126 by linker stub unwind descriptors.
127 (frameless_function_invocation): Likewise.
128 (frame_chain_valid): Likewise.
129 * paread.c (compare_unwind_entries): New function for sorting
130 unwind table entries.
131 (read_unwind_info): Rewrite to remove dependency on host endianness.
132 Read in data from the $UNWIND_END$ subspace which contains linker
133 stub unwind descriptors. Merge that data into the basic unwind
136 * hppab-nat.c (_initialize_kernel_u_addr): Delete unwanted functions.
138 Mon Jan 17 22:00:15 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
140 * xcoffread.c (read_xcoff_symtab, case C_FILE): Accept the name
141 from either the symbol name or the auxent.
142 * coffread.c, symfile.h (coff_getfilename): Renamed from getfilename,
145 Mon Jan 17 13:35:01 1994 Fred Fish (fnf@cygnus.com)
147 * Makefile.in (ALLPARAM): Change irix5.h to nm-irix5.h.
149 Mon Jan 17 12:35:42 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
151 * README: Update notes for alpha port.
153 Mon Jan 17 11:15:57 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
155 * i960-tdep.c (i960_fault_to_signal): Return TARGET_SIGNAL_ILL
156 for operation fault, constraint fault, and type fault.
158 Sun Jan 16 12:46:01 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
160 * Makefile.in (init.c): Add comment explaining formatting conventions.
162 * c-exp.y (parse_number): Assign to temporary between the right
163 shifts, to work around a bug in the SCO compiler.
165 * Makefile.in (ALLCONFIG, ALLPARAM, ALLDEPFILES, HFILES_NO_SRCDIR):
166 Add various files which were added to GDB recently.
168 * xcoffread.c (process_xcoff_symbol): Only change 'V' to 'S' if not
171 * Makefile.in: Add mostlyclean target.
173 Sat Jan 15 10:20:13 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
177 Sat Jan 15 18:27:34 1994 Per Bothner (bothner@kalessin.cygnus.com)
179 * main.c (show_commands): Make return type of extern
180 history_get be HIST_ENTRY, rather than struct _hist_entry.
181 (The latter loses with the upcoming merged readline.)
183 Sat Jan 15 10:20:13 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
185 * minsyms.c (prim_record_minimal_symbol_and_info): Make tempstring
186 const char *, not char *.
188 * symtab.h (struct symbol): Make section short, not unsigned short.
190 * symtab.c (lookup_symbol): Add comment about QUIT here.
192 * utils.c (fputs_unfiltered): Call fputs, not fputs_maybe_filtered.
194 * c-exp.y (parse_number): Check for overflow regardless of range
195 checking. Fix overflow check to use unsigned LONGEST, not
198 * c-exp.y (parse_number): Make it so that integer constants are
199 builtin_type_long_long if builtin_type_long isn't big enough or if
200 an "LL" suffix is used. Properly handle "UL" or "LU" suffixes.
202 * c-typeprint.c (c_type_print_varspec_suffix, case TYPE_CODE_FUNC):
203 Print our "()" first, then recurse for the target type.
205 Fri Jan 14 21:55:39 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
207 * remote-udi.c (udi_create_inferior): Quote empty execfile argument.
209 * gdbserver/low-lynx.c: Include <sys/wait.h> not "/usr/include/wait.h".
211 Fri Jan 14 14:17:06 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
213 * utils.c (request_quit): Re-establish signal handler regardless
216 * config/mips/xm-irix4.h: Define HAVE_TERMIOS.
218 Fri Jan 14 21:55:39 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
220 * i960-tdep.c: Include target.h.
222 Fri Jan 14 17:12:28 1994 Stan Shebs (shebs@andros.cygnus.com)
224 * lynx-nat.c (sys/wait.h): Don't use absolute pathname.
226 Fri Jan 14 11:06:10 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
228 * lynx-nat.c (child_wait): Fix thinkos in struct target_waitstatus
229 changes (status -> ourstatus; declare status, etc.).
230 * config/nm-lynx.h: Fix child_wait prototype and include target.h.
232 Fri Jan 14 14:17:06 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
234 * Makefile.in (ALLPARAM): Add config/nm-lynx.h.
236 Fri Jan 14 11:49:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
238 * remote-mips.c (mips_request, mips_wait): Correct prototypes.
240 Fri Jan 14 11:37:17 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
242 * config/i386/xm-linux.h: Define HAVE_TERMIOS.
244 Fri Jan 14 01:04:36 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
246 * config/alpha/tm-alpha.h (CALL_DUMMY): Improve comment.
248 Thu Jan 13 10:32:38 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
250 * remote-vx.c (vx_wait): Only call i960_fault_to_signal if I80960
251 is defined. Otherwise just report TARGET_SIGNAL_UNKNOWN.
253 * mips-tdep.c (mips_push_arguments): Byteswap struct_addr before
256 Add search to target vector (#if 0'd until after 4.12):
257 * target.h (to_search, target_search): Add.
258 * gdbcore.h, core.c (generic_search): Add.
259 * remote.c (remote_search): Add.
260 * a29k-tdep.c (init_frame_info): Use target_search to find traceback
263 * printcmd.c (print_address_symbolic): If set print fast-symbolic-addr
264 is on, call find_pc_function rather than relying just on the minimal
265 symbols (probably only matters for symbol readers which don't put
266 statics in the minimal symbols, but changing this strikes me as
267 not conservative enough).
268 Initialize name_location in all cases.
269 If no symbol and no msymbol, don't print anything symbolic.
271 * a29k-tdep.c (push_dummy_frame): Add comment about saving lr0.
273 Wed Jan 12 20:53:16 1994 John Gilmore (gnu@cygnus.com)
275 * printcmd.c (print_address_symbolic): Make it search the
276 symtabs for variables as well as functions. Add `set print
277 fast-symbolic-addr' and default it to fast (the old way).
278 Print line numbers for data items as well as functions.
280 * symtab.c (find_addr_symbol): Return the symtab and the symbol
281 address, if a symbol is found (take two more args pointing to
282 where to store these results).
284 * symtab.h (find_addr_symbol): Add prototype.
286 Wed Jan 12 19:32:11 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
288 * objfiles.h: Fix comments to reflect the fact that the phrase
289 "top of stack" always refers to where the pushing and popping takes
290 place, regardless of whether it is at the highest or lowest address.
292 Wed Jan 12 13:23:37 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
294 * mdebugread.c (parse_symbol): Do not set TYPE_TAG_NAME for
295 compiler generated tag names.
296 * mdebugread.c (parse_type): Handle cross references to qualified
298 * valops.c (value_struct_elt): Improve error message if the
299 address of a method is requested from an object instance.
300 * valops.c (search_struct_method): Make name_matched non-static
301 to get it initialized correctly.
302 * config/i386/nm-i386sco.h (CANNOT_STORE_REGISTER): Define to
303 exclude segment register which are not writable on newer SCO versions.
305 Wed Jan 12 14:44:45 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
307 * go32-xdep.c: Remove unused function uerror.
308 (sigsetmask): Declare return type. Declare argument (to match the
309 way it is called). Explicitly return 0.
311 Wed Jan 12 01:44:25 1994 John Gilmore (gnu@cygnus.com)
313 * symtab.h (struct symbol, general_symbol_info, minimal_symbol,
314 partial_symbol): Shrink the storage sizes of symbols, by making
315 enums into 1-byte bitfields when compiled __GNUC__, moving all the
316 enums and small ints to the end of each struct to improve
317 alignment, and switching the section number from int to unsigned
320 Wed Jan 12 00:16:26 1994 John Gilmore (gnu@cygnus.com)
322 * symtab.c (find_addr_symbol): New routine that will find the nearest
323 symbol associated with an address. It does so by exhaustive
324 search of the symtabs, so it's slow but complete.
326 Tue Jan 11 23:57:30 1994 John Gilmore (gnu@cygnus.com)
328 * coffread.c (read_coff_symtab): Set PC bounds of _globals_ symtab
329 to [0,0] rather than [0, end of first source file]. This avoids
330 problems with other parts of GDB looking for linetables in the
331 _globals_ symtab. Eliminate variables num_object_files and
332 first_object_file_end.
334 Tue Jan 11 00:53:46 1994 John Gilmore (gnu@cygnus.com)
336 * a29k-tdep.c (init_frame_info): Cast null arg to examine_tag.
337 (pop_frame): Restore PC2 and LR0 from dummy frames.
338 (push_dummy_frame): Save PC2 and LR0 into dummy frames.
339 (setup_arbitrary_frame): Handle 3 args and set up real frames.
340 * config/a29k/tm-a29k.h (FRAME_NUM_ARGS): Update comments.
341 (DUMMY_FRAME_RSIZE): Add 2 longwords for PC2 and LR0.
342 (SETUP_ARBITRARY_FRAME): Define.
344 Tue Jan 11 06:59:10 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
346 * infrun.c, config/mips/tm-irix5.h: Remove #if 0'd AT_FUNCTION_START.
348 Tue Jan 11 14:27:03 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
350 * remote-udi.c (udi_resume): Correct prototype.
352 Tue Jan 11 11:10:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
354 * config/pa/tm-hppa.h (FRAME_FIND_SAVED_REGS): Call
355 hppa_frame_find_saved_regs.
356 * hppa-tdep.c (dig_fp_from_stack): Delete function.
357 (prologue_inst_adjust_sp): New function.
358 (is_branch, inst_saves_gr, inst_saves_fr): New functions.
359 (skip_prologue): Completely rewrite to use unwind information.
360 (hppa_frame_find_saved_regs): Likewise.
362 Tue Jan 11 06:59:10 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
364 * remote-mips.c (mips_wait): Use new function mips_signal_from_protocol
365 to convert a signal number with appropriate bounds checking.
367 * remote-mips.c (mips_wait): Fix typos (0x177 -> 0177, 0x377 -> 0377).
369 Tue Jan 11 00:53:46 1994 John Gilmore (gnu@cygnus.com)
371 * stack.c (frame_info): If FRAME_FIND_SAVED_REGS isn't defined,
372 print a newline to end the display anyway.
374 * sparc-tdep.c (sparc_pop_frame): Pop the fsr and csr (float and
375 coprocessor status regs) when popping a frame. This fixes
376 float exceptions that occur after calling inferior functions.
378 * sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
379 Read and write the fsr (float status register) to/from the child
380 process along with the float regs. Remove Peter Schauer's change
381 of May 24 '93, which has higher overhead and doesn't solve the
382 real problem (which was that FSR wasn't being set).
384 Mon Jan 10 23:16:42 1994 John Gilmore (gnu@cygnus.com)
386 * a29k-tdep.c (examine_prologue): Don't worry if the ASGEQ
387 stack overflow check isn't right after the register stack
388 adjustment instruction. Metaware R2.3u compiler moves other
389 things in front of it. This fix isn't perfect but is what's
392 Mon Jan 10 20:08:23 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
394 * c-valprint.c (c_val_print): Treat TYPE_CODE_RANGE like TYPE_CODE_INT.
396 * config/alpha/alpha-netware.mt: Rename to alpha-nw.mt for 14
398 * configure.in: Change accordingly.
400 Mon Jan 10 15:48:36 1994 Tom Lord (lord@rtl.cygnus.com)
402 * m68k-stub.c, sparc-stub.c: removed spurious introduction of
403 _filtered io routines from these two files.
405 Fri Jan 7 12:42:45 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
407 * config/i386/tm-i386v.h, config/m68k/tm-m68k.h, config/mips/tm-mips.h,
408 config/vax/tm-vax.h (CALL_DUMMY_BREAKPOINT_OFFSET): Define.
409 * mdebugread.c (parse_symbol): Handle enum sh.type produced by
411 * mdebugread.c (add_line): Handle zero linenos produced by DEC c89.
413 Fri Jan 7 12:55:25 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
415 * utils.c (print_sys_errmsg): Call gdb_flush (gdb_stdout) before
416 printing to gdb_stderr.
418 * remote-udi.c (udi_kill): Don't close the connection, just set
419 inferior_pid to zero.
420 (udi_mourn): Call remove_breakpoints.
422 * remote-udi.c: Remove obsolete need_artificial_traps comment.
424 * i386b-nat.c (sregmap): If sEAX, etc., not defined, use tEAX, etc.
426 Thu Jan 6 07:17:53 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
428 * symtab.c (lookup_symbol): Don't try adding .c to the name.
430 * remote-bug.c: At the start of each section, reset srec_frame
433 * target.h: Add TARGET_WAITKIND_LOADED and TARGET_WAITKIND_SPURIOUS.
434 * target.c (store_waitstatus): Add CHILD_SPECIAL_WAITSTATUS hook.
435 * infrun.c (wait_for_inferior): Replace SIGTRAP_STOP_AFTER_LOAD with
436 code which looks for those two waitkinds. Use switch statement.
437 * config/rs6000/tm-rs6000.h: Replace SIGTRAP_STOP_AFTER_LOAD with
438 CHILD_SPECIAL_WAITSTATUS.
440 * procfs.c (procfs_wait): Fix argument name to match 4 Jan changes.
441 * Move target_signal_from_host, target_signal_to_host, and
442 store_waitstatus from inftarg.c to target.c. procfs needs them.
443 * target.c: Include "wait.h" and <signal.h>.
444 * target.h, infrun.c (proceed), proceed callers: Pass new code
445 TARGET_SIGNAL_DEFAULT instead of -1. This avoids problems with
446 enums being treated as unsigned and is cleaner.
447 * infrun.c (signals_info): Don't print TARGET_SIGNAL_DEFAULT or
449 * infcmd.c (signal_command), infrun.c (signals_info):
450 Don't allow user to specify numeric equivalent of
451 TARGET_SIGNAL_DEFAULT.
453 Tue Jan 4 15:34:36 1994 Stu Grossman (grossman@cygnus.com)
455 * config/alpha/alpha-netware.mt: New target support for Alpha
457 * configure.in: Add alpha-*-netware* target.
459 Tue Jan 4 14:51:35 1994 Stan Shebs (shebs@andros.cygnus.com)
461 * remote-mips.c (mips_wait): Fix ref to TARGET_WAITKIND_STOPPED.
463 Tue Jan 4 09:47:14 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
465 * target.h: Add enum target_waitkind, enum target_signal, and
466 struct target_waitstatus. Change status argument to target_wait to
467 be struct target_waitstatus * instead of int *.
468 * target.h, infrun.c, all targets: Change type of signal arguments
469 to resume(), proceed(), and target_resume() from int to enum
471 * All targets (*_wait, *_resume): Change accordingly.
472 * infcmd.c (program_info, signal_command), throughout infrun.c,
473 * fork-child.c, solib.c, hppa-tdep.c, osfsolib.c: Use this stuff.
474 * convex-xdep.c, convex-tdep.c: Add FIXME's (getting the Convex
475 signal code stuff right with the new signals would be non-trivial).
476 * inferior.h (stop_signal): Make it enum target_signal not int.
477 * target.c, target.h (target_signal_to_string, target_signal_to_name,
478 target_signal_from_name): New functions.
479 * inftarg.c, target.h (target_signal_to_host, target_signal_from_host,
480 store_waitstatus): New functions.
481 * procfs.c (procfs_notice_signals): Use them.
482 * i960-tdep.c (i960_fault_to_signal): New function, to replace
484 * config/i960/tm-i960.h: Don't define PRINT_RANDOM_SIGNAL.
486 * objfiles.c (build_objfile_section_table): Don't abort() if
487 objfile->sections is already set.
489 * objfiles.c (add_to_objfile_sections): Check SEC_ALLOC not SEC_LOAD
490 to match recent change to exec.c.
494 * main.c (print_gdb_version): Change year to 1994.
