2 | ||
3 | Cleanup for release 3.94.2: | |
4 | ||
5 | * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD | |
6 | include files. Roll version to 3.94.2. | |
7 | ||
8 | * coffread.c (init_stringtab): Read length into unsigned char | |
9 | array before swapping; don't assume 32-bit longs. | |
10 | ||
11 | * target.c (target_info): Don't bother with get_sym_file, just use | |
12 | the symfile global variable. | |
13 | * symtab.h, symfile.c (get_sym_file): Delete it. | |
14 | ||
15 | * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes. | |
16 | (define_symbol): Set symbol line number to 0 if not gcc-compiled. | |
17 | (read_type): Replace one more error() with complain(). | |
18 | ||
19 | * mipsread.c (parse_partial_symbols): Replace printf with complain. | |
20 | ||
21 | * i960-tdep.c: Fix copyright attribution. | |
22 | ||
23 | * config.gdb: Quote all backquotes in doublequotes. You can | |
24 | quote me on that. BSD 4.4 shell found this one. | |
25 | ||
26 | * infptrace.c (throughout): The third argument to ptrace is an | |
27 | int *, not an int. | |
28 | ||
29 | * infrun.c (wait_for_inferior): When program has terminated, we | |
30 | have to call target_terminal_ours before we pop that target off | |
31 | the stack (e.g. before a call to target_kill or | |
32 | target_mourn_inferior). This fixes problem where a program | |
33 | terminates, then GDB stops for (tty output) and you have to type | |
34 | "fg" to the shell to resume it. FIXME: This code for what to | |
35 | do after termination really should be in normal_stop instead. | |
36 | ||
37 | * gdbcore.h (read_memory_check): Change declaration; it changed | |
38 | names months ago. | |
39 | ||
40 | * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD | |
41 | 4.4 prereleases, this avoids a bug in their sgtty compatability | |
42 | support. | |
43 | * remote.c: Use terminal.h rather than hand-rolling the same. | |
44 | ||
45 | * signame.c, signame.h (psignal): Arg is unsigned, not int. | |
46 | * utils.c (strsave, strstr): Fix arg types. | |
47 | * valprint.c (val_print): lint | |
48 | ||
49 | MIPS symbol table support from Per Bothner: | |
50 | ||
51 | * symfile.c (symtab_fns): Remove initializer table that needs to | |
52 | be hacked for each new symbol file format supported. | |
53 | (add_symtab_fns): New function, chains symbol table | |
54 | handlers into the global list. | |
55 | (symfile_init): Search this list. | |
56 | * symfile.h: Add next pointer, declare add_symtab_fns. | |
57 | * coffread.c (_initialize_coffread): Call add_symtab_fns. | |
58 | * dbxread.c (_initialize_dbxread): Call add_symtab_fns. | |
59 | ||
60 | * mipsread.c (psymtab_to_symtab_1): return void instead of (struct | |
61 | symbol *). Thus, we no longer need the hack to trash | |
62 | pst->filename. Good, since that hack confused code in symfile.c! | |
63 | ||
64 | (reorder_symtabs, destroy_all_symtabs): Removed static | |
65 | all_symtabs, which was used to qsort symtabs in reorder_symtabs. | |
66 | Instead, the latter now uses a temporary array (stack-allocated | |
67 | from an obstack, and then freed). | |
68 | ||
69 | (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they | |
70 | haven't been set in the outermost stBlock of a procedure. This was | |
71 | a problem with f77 binaries on Ultrix 4.?. | |
72 | ||
73 | (new_symtab, new_symbol, new_type): Continue changing code to use | |
74 | obstacks more and otherwise conform to dbxread internal style. | |
75 | Made the free_code of symtabs be free_linetable (as in dbxread) | |
76 | instead of free_contents. This implies memory leaks when reading | |
77 | a new symbol table, until the conversion is finished. Did change | |
78 | (struct symbol) and (struct type) to be allocated on the | |
79 | symbol_obstack. Blocks and blockvectors are among the things | |
80 | still "leaking." | |
81 | ||
82 | * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been | |
83 | tested much, but it solved one problem (reported by Meissner), and | |
84 | cleans up some other things. The problem happened when an | |
85 | included file contains actual code (functions) and not just | |
86 | definitions. The mips coff is a little inconvenient there, since | |
87 | it may cause a procedure to be mapped to the wrong psymtab. | |
88 | ||
89 | * mips-tdep.c (heuristic_proc_desc): Minor cleanup. | |
90 | * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME, | |
91 | this will need work for the new core paradigm. | |
92 | ||
93 | Opcode patches from the net: | |
94 | ||
95 | * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and | |
96 | ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were | |
97 | missing altogether - they are added here. From Bruce Bauman. | |
98 | * mips-opcode.h: The low mask for C0 instructions was too small. | |
99 | From Garrett Lau. I modified the fix to check the entire 32-bit | |
100 | opcode. | |
101 | ||
102 | * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce | |
103 | Bauman. | |
104 | ||
105 | Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com) | |
106 | ||
107 | Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04): | |
108 | ||
109 | * dbxread.c (read_type): Pointer subtraction (value_sub in | |
110 | valarith.c) sometimes failed because the types of the | |
111 | pointers being subtracted were not identical. | |
112 | These differed because dbxread.c was allocating pointer types | |
113 | using dbx_alloc_type+smash_to_pointer_type instead of | |
114 | lookup_pointer_type. I failed to find a justification for the | |
115 | former, so I changed it to use the latter. Similarly, I | |
116 | replaced smash_to_function_type by lookup_function_type, | |
117 | and smash_to_reference_type by lookup_reference_type. | |
118 | ||
119 | * mipsread.c (parse_symbol, upgrade_type, parse_procedure, | |
120 | _initialize_mipsread): corresponding changes. | |
121 | ||
122 | * symtab.c (smash_to_{pointer,reference,function}_type): eliminate. | |
123 | ||
124 | * source.c (mod_path): Do tilde_expand on each component of the path, | |
125 | rather than on the (list of) paths as a whole. | |
126 | (print_source_lines): Set first_line_listed in addition to | |
127 | current_source_symtab and current_source_line. If the source was | |
128 | not findable, after a "dir" command to fix the problem, | |
129 | a "list" would get the wrong lines. | |
130 | ||
131 | While I was there... (gnu): | |
132 | ||
133 | * dbxread.c (read_type): Change error to complaint. | |
134 | ||
135 | Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com) | |
136 | ||
137 | First attempt at detailed understanding of symbol table memory alloc. | |
138 | ||
139 | * dbxread.c (dbx_symfile_read): Free our string table if we | |
140 | aren't the mainline. Free the "info" struct since we're done with | |
141 | it. | |
142 | (init_psymbol_list): Free any previously allocated psymbol lists. | |
143 | (): FIXME: Should realloc-down the psymbol lists when done reading | |
144 | the main symbol file? | |
145 | ||
146 | * symmisc.c (free_symtab): Free fullname field too. | |
147 | ||
148 | * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D. | |
149 | (REGISTER_ADDR): Make result type unsigned int. | |
150 | ||
151 | * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that | |
152 | define REGEX must also define REGEX1 (its dependency). | |
153 | ||
154 | Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com) | |
155 | ||
156 | * tconfig/i960: No longer works, points you at vxworks960 or | |
157 | nindy960. | |
158 | ||
159 | * xgdb.c, XGDB-README: Remove file. Users can get the much | |
160 | better xxgdb. | |
161 | * Makefile.dist: Remove all trace of xgdb. | |
162 | ||
163 | * breakpoint.c (breakpoint_1): Pass demangle arg to | |
164 | print_address_symbolic. | |
165 | (clear_breakpoints): Remove unused function. | |
166 | (breakpoint_re_set_one): Guts of breakpoint_re_set. | |
167 | (breakpoint_re_set): Use catch_errors to do them all anyway. | |
168 | ||
169 | * gdb-int.texinfo (Host versus Target): Add section on what is | |
170 | a "host" feature versus what is a "target" feature. | |
171 | ||
172 | * infcmd.c (path_command, path_info): Handle the PATH variable | |
173 | (object search path) as conveniently as the source search path. | |
174 | * environ.c (set_in_environ): Set some vars in GDB's environment, | |
175 | in addition to the child's. PATH, G960BASE, G960BIN for starters. | |
176 | * source.c (mod_path): New function, from guts of | |
177 | directory_command, modifies a path. Used by path_command. | |
178 | (directory_command): Call it. | |
179 | * defs.h (strsave): Declare. | |
180 | ||
181 | * utils.c (sevenbit_strings): Add new printing option. | |
182 | (printchar): Use it. | |
183 | (strsave): Provide this handy helper routine. | |
184 | (set_width_command): Rename set_screen_width_command. | |
185 | (_initialize_utils): "set screen-width" => "set width"; | |
186 | "set screen-height" => "set height"; add sevenbit-strings. | |
187 | ||
188 | * infcmd.c (do_registers_info): Print floating point registers | |
189 | in raw hex as well as float format, regardless of whether it is | |
190 | a "virtual" convertible register. | |
191 | * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float | |
192 | regs as a double, just in case it's being used that way. | |
193 | * values.c (unpack_long): Comment on array/function coercion. | |
194 | (unpack_double): Argument is in target byte order now. For | |
195 | integer arguments, just call unpack_long and float the result. | |
196 | * m68k-tdep.c: include defs.h for "const" handling. | |
197 | * remote-nindy.c: Use ieee-float stuff. | |
198 | (nindy_fetch_registers): Unpack double regs to host double, then | |
199 | to extended. | |
200 | (nindy_store_registers): Pack extendeds to host double, flip | |
201 | around by misusing unpack_double, send as target double. | |
202 | ||
203 | * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of | |
204 | zero, as when stopped at the first instruction of a process. | |
205 | ||
206 | * blockframe.c: Fix filename in comment (param.h => tm.h). | |
207 | * sparc-tdep.c (skip_prologue): More explicit nudging comments. | |
208 | * tm-68k.h: Fix typos. | |
209 | ||
210 | Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com) | |
211 | ||
212 | Changes from a bringup on the DEC Vax under Ultrix 4.0. | |
213 | ||
214 | * coredep.c (fetch_core_registers): Pass end-address of register | |
215 | section to register_addr as expected. Don't call supply_register | |
216 | if we'd just pass it garbage. | |
217 | ||
218 | * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix. | |
219 | ||
220 | * exec.c (xfer_memory): Use boolean xfer_fn result, not int. | |
221 | ||
222 | * target.c (push_target, target_info): Cast enums to int for < or | |
223 | > comparison. | |
224 | ||
225 | * stack.c (print_frame_info): Identify source file & line | |
226 | even if we can't print it. | |
227 | ||
228 | * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0. | |
229 | ||
230 | Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com) | |
231 | ||
232 | Clean up IEEE floating point support. | |
233 | ||
234 | * ieee-float.h: New file. | |
235 | * ieee-float.c: Write real routines to convert between host | |
236 | doubles and various target IEEE extendeds. | |
237 | * m68k-xdep.c: Eliminate assembler code for extended floats. | |
238 | * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3, | |
239 | sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o. | |
240 | * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL, | |
241 | REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and | |
242 | double_to_ieee_extended. | |
243 | * i960-tdep.c: Define ext_format_i960. | |
244 | * m68k-tdep.c: Define ext_format_68881. | |
245 | * sparc-tdep.c: Define ext_format_sparc, though unused. | |
246 | * Makefile.dist (HFILES): Add ieee-float.h. | |
247 | * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT | |
248 | macros. | |
249 | ||
250 | Obsolete the "coffstrip" program in favor of using BFD's strip. | |
251 | ||
252 | * nindy-share/coffstrip.c: Remove file. | |
253 | * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip. | |
254 | * Makefile.dist: Remove references to nindy-share/coffstrip.c. | |
255 | * tconfig/nindy960: Remove reference to coffstrip.o. | |
256 | ||
257 | * Makefile.dist: Roll version number to 3.94.1 (not yet final). | |
258 | ||
259 | Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com) | |
260 | ||
261 | * symfile.h: Add symfile_bfd, common between dbxread and coffread. | |
262 | * dbxread.c: Remove static symfile_bfd. | |
263 | * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though | |
264 | it is not used yet. | |
265 | * inftarg.c (child_detach): Pop the child_ops vector if the | |
266 | detach is successful. | |
267 | * remote-nindy.c (nindy_create_inferior): Don't push a new | |
268 | nindy_ops since nindy uses the same one for execution and memory | |
269 | examination anyway. | |
270 | * core.c (core_ops): Use child_attach and child_create_inferior | |
271 | rather than default attach and create_inferior functions. | |
272 | ||
273 | Handle floating point registers in core files. | |
274 | ||
275 | * sparc-xdep.c (fetch_core_registers): Rewrite for float support. | |
276 | * sun3-xdep.c (fetch_core_registers): Rewrite for float support. | |
277 | This version untested since BFD doesn't yet support sun3 core | |
278 | files. | |
279 | * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling | |
280 | conventions. Fix comments and style. This version has not | |
281 | been compiled yet, since we have no HP inhouse. | |
282 | * core.c (get_core_registers): Look for two sections, ".reg" | |
283 | and ".reg2", and pass both to fetch_core_registers sequentially. | |
284 | ||
285 | Revise directory path yet again. | |
286 | ||
287 | * source.c (forget_cached_source_info): Not static any more. | |
288 | (init_source_path): New default source path is "$cdir:$cwd". | |
289 | (dir_command): Handle variable arguments ($cdir, $cwd). | |
290 | (source_info): Print "Compilation directory" rather than | |
291 | "Originally compiled in" to remind people of $cdir. | |
292 | (openp): If the path contains $cwd, use current directory. | |
293 | (open_source_file): If compilation directory is known, replace | |
294 | first $cdir in path with the compilation directory. | |
295 | (print_source_lines): Even if we can't print the lines, set the | |
296 | current symtab and line for future commands like "info source" or | |
297 | "breakpoint". Also, error message now contains the file name, | |
298 | line number, and file access error message. | |
299 | (_initialize_source): Fix help text to describe changes. | |
300 | * main.c (cd_command): Forget cached source info when we chdir. | |
301 | * utils.c (strstr): Add simple implementation. | |
302 | ||
303 | Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com) | |
304 | ||
305 | * coffread.c (read_one_sym, init_linetable, init_stringtab): | |
306 | Byte-swap COFF symbol tables if necessary when reading them in. | |
307 | Use complain() to replace error message in one spot. Needs | |
308 | corresponding change in bfd/coff-code.h to make some symbol | |
309 | swapping routines non-static. | |
310 | ||
311 | Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com) | |
312 | ||
313 | Merge changes from Eirik Fuller, for UTek. | |
314 | ||
315 | * defs.h (errno): Add declaration. | |
316 | * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c, | |
317 | hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c, | |
318 | i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c, | |
319 | remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c, | |
320 | symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate | |
321 | declarations of errno. | |
322 | ||
323 | * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB. | |
324 | ||
325 | * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via | |
326 | <rpc/rpc.h> and <rpc/types.h>. | |
327 | ||
328 | Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com) | |
329 | ||
330 | * i960-tdep.c (examine_prologue): Add new argument limit, | |
331 | which stops the scan at the end of the prologue, or at the PC. | |
332 | This fixes a problem where it walks down into the code for the | |
333 | user's statements if that code looks like function prologues. | |
334 | Mark Fox and I have been bouncing this code back and forth, making | |
335 | small changes to it. Callers changed to match. | |
336 | ||
337 | Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba) | |
338 | ||
339 | Cleanup for gdb-3.94 release final: | |
340 | ||
341 | * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all | |
342 | the .c files from vx-share and nindy-share, from the various | |
343 | macros, since they are not found via ALLDEPFILES. | |
344 | (SFILES): Add tm-i960.h. | |
345 | (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and | |
346 | ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files | |
347 | in the SUBDIR list. | |
348 | (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR. | |
349 | (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR. | |
350 | ||
351 | Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman) | |
352 | ||
353 | * am29k-tdep.c: Add contribution line. | |
354 | (examine_prologue): Cache information about function prologues in | |
355 | the misc-function-vector to avoid lots of references over the | |
356 | serial line while examining instructions. | |
357 | ||
358 | * core.c (core_close): New function made from cleanup_core. | |
359 | ||
360 | * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c, | |
361 | remote-vx.c, remote.c, target.c, target.h, | |
362 | Update target_ops vector to add attach, close, and load entries. | |
363 | Use add_syms_addr_command, not add_file_addr_command, for | |
364 | add_file. Break out close routine from existing code. | |
365 | ||
366 | * dbxread.c (really_free_pendings): Don't free pending_blocks; | |
367 | they are in an obstack. | |
368 | (read_dbx_symtab): Relocate end_of_text_addr in the psymtab. | |
369 | Lint. | |
370 | (define_symbol): Add symbol type parameter; change callers; | |
371 | pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow | |
372 | it to influence the symbol class on the i960. | |
373 | (define_symbol): Swap LOC_CONST's into target byte order. | |
374 | ||
375 | * exec.c (exec_close): New function. | |
376 | (exec_file_command): Call it. | |
377 | ||
378 | * findvar.c (read_relative_register_raw_bytes): Doc byte order, | |
379 | Fix byte order of frame pointer. | |
380 | (read_var_value): Result of 0 if var's value can't be found, | |
381 | e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and | |
382 | LOC_LABEL values to target order. Add LOC_LOCAL_ARG. | |
383 | (locate_var_value): Use read_var_value and use its lazy address | |
384 | as the location of the var's value. Lint. | |
385 | ||
386 | * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning | |
387 | instructions. | |
388 | ||
389 | * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove | |
390 | obsolete Intel versions in favor of vxgdb versions. | |
391 | (check_host, byteswap, byteswap_val, reorder_val): Eliminate | |
392 | code dealing with byte order of values, which Intel did in host byte | |
393 | order rather than gdb-4's target byte order. | |
394 | (i960_frame_chain_valid): Move to nindy-tdep.c. | |
395 | (examine_prologue, skip_prologue, frame_find_saved_regs, | |
396 | frame_args_address, leafproc_return, saved_pc_after_call, | |
397 | pop_frame): Add vxgdb versions from Mark Fox. | |
398 | (examine_prologue, frame_struct_result_address): Add code | |
399 | to deal with the saved value of G13 (struct return address | |
400 | pointer). | |
401 | (frame_args_address): Modify Mark's version to prefer the | |
402 | saved value over the current value in the topmost frame. | |
403 | Cache result in the frame info to avoid performance hair in | |
404 | callers. | |
405 | (print_fault): Add gdb960 code for printing faults. | |
406 | (_initialize_i960): Actually call check_host. | |
407 | ||
408 | * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended): | |
409 | add stub routines. FIXME, these currently just return zero! | |
410 | ||
411 | * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL. | |
412 | (attach_command): Call target_attach, not target_open, now. | |
413 | ||
414 | * infrun.c (normal_stop): Make global, not static, for vx_attach. | |
415 | (child_attach): Rename from child_open. | |
416 | (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero, | |
417 | don't confuse it with a zero step_resume_break_address. | |
418 | ||
419 | * inftarg.c (child_detach): Eliminate inferior_pid test. | |
420 | (child_files_info): Clean up message a bit. | |
421 | (child_ops): Use child_attach, not child_open, to attach. | |
422 | ||
423 | * mem-break.c: #ifdef out the whole file if BREAKPOINT is not | |
424 | set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from | |
425 | findvar.c to here, since it depends on the contents of the | |
426 | shadow_contents of breakpoints, but keep if #if 0 since it is | |
427 | never called. | |
428 | ||
429 | * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved | |
430 | from i960-tdep.c. | |
431 | ||
432 | * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint. | |
433 | (ptype_command, display_command): Eliminate have_inferior_p and | |
434 | have_core_file_p in favor of target_has_stack or | |
435 | target_has_execution. | |
436 | (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate | |
437 | code for actually finding the values of arguments, though we still | |
438 | keep track of the maximum stack offset for use in printing unnamed | |
439 | arguments. Handle missing FRAME_ARGS_ADDRESS. | |
440 | ||
441 | * remote-nindy.c (i960_print_fault): Move to i960-tdep.c. | |
442 | (struct nindy_regs): Define registers passed to/from nindy. | |
443 | (nindy_fetch_registers, nindy_store-registers): Translate between | |
444 | nindy and GDB formats for the registers. | |
445 | (dcache_init): Statically allocate the cache, since it was being | |
446 | allocated by a malloc that was never freed anyway. | |
447 | (nindy_create_inferior): Error, not core dump, if no exec file. | |
448 | (nindy_before_main_loop): Use target_load, not target_add_file. | |
449 | ||
450 | * remote-vx.c (net_load): Specify large timeout for load | |
451 | requests. Allow user to break out with INTERRUPT. | |
452 | (net_break): Remove useless code, clean up. Change callers. | |
453 | (parse-args, skip_white_space, find_white_space): Clean up arg | |
454 | parsing to cope with quoted strings. | |
455 | (net_wait, net_quit): Never call error, just return status. | |
456 | (vx_read_register, vx_write_register): Cleanup status checking. | |
457 | #ifdef the code based on which CPU we are using (960 or 68k), | |
458 | FIXME, this should be completely general but it isn't yet. | |
459 | (vx_xfer_memory, vx_resume): Cleanup status checking. | |
460 | (vx_run_files_info): Improve message. | |
461 | (vx_load_command): Renamed from vx_add_file_command. Allow load | |
462 | to be interrupted. | |
463 | (net_ptrace): Remove unused routine. | |
464 | (vx_wait): Adopt code from vxgdb960 to cope with broken | |
465 | connections to target machine and prompt to disconnect. Remove | |
466 | debug printouts. Map some EVENT_'s to SIGnals. | |
467 | (add_symbol_stub, vx_open): Print names of object files we found, | |
468 | and "ok" if we read their symbols OK. Clarify output in general. | |
469 | (vx_attach, vx_detach, vx_kill): Add these commands. | |
470 | (vx_convert_from_virtual, vx_convert_to_virtual): Simplify. | |
471 | (vx_run_ops): Turn off all_mem, to avoid spurious msg in the | |
472 | "info files" output, and create_inferior, since we already have | |
473 | an inferior. | |
474 | ||
475 | * stack.c (frame_info): Replace Frame_unknown with 0. | |
476 | (print_frame_arg_vars): Handle LOC_LOCAL_ARG. | |
477 | (return_command): Pop until the PC matches as well as the FP, | |
478 | so it works even if the FP is shared with another function, | |
479 | as in "frameless" or "leaf" procedures. | |
480 | ||
481 | * symfile.c (load_command): renamed from add_file_target_command. | |
482 | (add_syms_addr_command): renamed from add_file_addr_command. | |
483 | (add_syms_command): Stub to call target_add_syms. | |
484 | (_initialize_symfile): Change command names and descriptions, | |
485 | add-file => add-syms, and load from alias to its own command. | |
486 | ||
487 | * target.c (kill_or_be_killed, maybe_kill_then_attach, | |
488 | maybe_kill_then_create_inferior): Default for attempts to start | |
489 | a process, if one is already running, is to ask about killing | |
490 | it and retry if yes. | |
491 | (upstack_create_inferior): #if-0 it, strata obsolete it. | |
492 | (push_target, unpush_target, pop_target): to_close() a target | |
493 | before unstacking it. | |
494 | (target_info): Renamed from target_files_info. | |
495 | (_initialize_targets): Rename "i files" as "i target", accessible | |
496 | under both names. | |
497 | ||
498 | * target.h: Improve comments about the target_ vectored routines. | |
499 | ||
500 | * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h. | |
501 | Convert commenting style to standard GNU style. | |
502 | (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized. | |
503 | (SKIP_PROLOGUE): No longer a no-op. | |
504 | (SAVED_PC_AFTER_CALL): Now handles leaf procedures. | |
505 | (*_REGNUM): Sort register numbers. | |
506 | (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE, | |
507 | MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE, | |
508 | REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs | |
509 | are now 10 byte extendeds, not 8 byte doubles. | |
510 | (FRAME_CHAIN_VALID): Make this config-dependent, since it differs | |
511 | for nindy versus vxworks targets. FIXME, this should possibly go | |
512 | in the target vector. | |
513 | (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both | |
514 | frame_saved_regs and arg pointer with each frame. | |
515 | (FRAMELESS_FUNCTION_INVOCATION): New leafproc support. | |
516 | (FRAME_ARGS_ADDRESS): Use cached result. | |
517 | (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing. | |
518 | (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn. | |
519 | (PRINT_RAMDON_SIGNAL): Call print_fault. | |
520 | (POP_FRAME): Now works. | |
521 | ||
522 | * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific | |
523 | option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID, | |
524 | BREAKPOINT, and DECR_PC_AFTER_BREAK are here. | |
525 | (ADDITIONAL_OPTION_HANDLER): use target_load, not | |
526 | target_add_file. | |
527 | ||
528 | * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific | |
529 | startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here. | |
530 | ||
531 | * valarith.c (value_subscripted_rvalue): Avoid handling | |
532 | floats and doubles specially; it gave alignment errors. Lint. | |
533 | ||
534 | * valops.c (value_of_variable, value_of_this): Error if unknown | |
535 | value. | |
536 | ||
537 | * valprint.c (print_floating): Bcopy rather than pointer-deref, | |
538 | to avoid alignment problems. | |
539 | (value_print): Handle unknown value address. | |
540 | (cplus_val_print): Two args are ignored; remove them. Change caller. | |
541 | (val_print): Use unpack_long rather than pointer-deref. | |
542 | ||
543 | * values.c: Lint. | |
544 | (unpack_long, unpack_double): Use bcopy rather than pointer-deref | |
545 | to avoid alignment problems. | |
546 | (value_being_returned): Error if return value unknown. | |
547 | (set_return_value): Add bogosity warning, FIXME. * | |
548 | ||
549 | * TODO: A woman's work is never done. | |
550 | ||
551 | * Makefile.dist: Distribute REMOTE_OBS into tconfig files. | |
552 | Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES. | |
553 | Add ieee-float.o to OBS. | |
554 | * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired | |
555 | REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE. | |
556 | * tconfig/i960: FIXME. Half-merge, produce warning if config'd. | |
557 | ||
558 | Changes to generalize the VxWorks RPC protocol slightly, to handle | |
559 | i960 as well as 68000. | |
560 | ||
561 | * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add. | |
562 | * vx-share/reg.h: Produce i960 regs #ifdef I80960 | |
563 | * vx-share/xdr_ptrace.c: Skip FPA registers if 960. | |
564 | * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl. | |
565 | * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine. | |
566 | * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp | |
567 | for i960. Change xdr_vectors to xdr_opaques for 68k registers, | |
568 | so they will move in target byte order rather than network | |
569 | byte order (happens to be the same). | |
570 | ||
571 | Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com) | |
572 | ||
573 | * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block. | |
574 | ||
575 | Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com) | |
576 | ||
577 | * am29k-pinsn.c, | |
578 | Add contribution lines to various files, showing where they | |
579 | came from. | |
580 | ||
581 | * breakpoint.c (break_insn, check_break_insn_size, | |
582 | read_memory_nobpt): Remove to mem-break.c. | |
583 | ||
584 | * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to | |
585 | HOST_BYTE_ORDER. | |
586 | ||
587 | * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table | |
588 | entry has bad register number. This change is not | |
589 | tested in this release, FIXME. | |
590 | ||
591 | * frame.h: Eliminate Frame_unknown in favor of a simple zero. | |
592 | tm-vax.h: Ditto. | |
593 | ||
594 | * value.h: Force value's contents field to be aligned to hold | |
595 | at least a double or a long long (if supported). This avoids | |
596 | doing bcopy's in and out of the contents field. | |
597 | ||
598 | (step_1): Avoid coredump under obscure circumstances when we | |
599 | have no frame. | |
600 | ||
601 | * symtab.h (misc_info): Add field to misc function vector for | |
602 | any kind of cached information the target code desires. AMD | |
603 | 29000 uses this to avoid repeating examine_function_prologue's. | |
604 | ||
605 | * coffread.c: Lint. Remove static symfile, read_section_header. | |
606 | core.c (have_core_file_p): Lint: remove. | |
607 | expprint.c (print_subexp): Lint. | |
608 | infptrace.c, valops.c, valprint.c: lint. | |
609 | ||
610 | Roll in changes from vxgdb-5.0.1: | |
611 | ||
612 | * symtab.h: Comment byte order of each address class. Add | |
613 | LOC_LOCAL_ARG for frame-relative args (960). | |
614 | expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used. | |
615 | symtab.c, symmisc.c: ditto. | |
616 | ||
617 | * infrun.c (init_wait_for_inferior): Clear stop_signal. | |
618 | ||
619 | * remote.c (remote_resume): Error if resume with a signal. | |
620 | ||
621 | * symfile.c (prim_record_misc_function): Clear misc_info. | |
622 | (fill_in_vptr_fieldno): Check stub type of arg. | |
623 | ||
624 | * valops.c (value_cast): Avoid looking up names of types whose | |
625 | name we don't know, to prevent coredump. Sun CC produces typedef | |
626 | rtx and the name of *rtx is zero... | |
627 | ||
628 | Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com) | |
629 | ||
630 | Roll in changes from final AMD 29000 port (Tiemann). | |
631 | ||
632 | tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K | |
633 | for ../include/a.out.encap.h. This might not work now that BFD | |
634 | is separately compiled. Instead, BFD support for encap will have | |
635 | to translate machine type 29k into the right COFF_MAGIC. | |
636 | ||
637 | * infcmd.c: Remove references to inferior_pid that aren't used | |
638 | in actual ptrace calls; use target_has_execution, etc. | |
639 | (have_inferior_p): Remove function. | |
640 | (program_info): Print target info rather than "process number"; | |
641 | avoid gratuitous messages unless from_tty. | |
642 | (run_stack_dummy, finish_command): Set proceed_to_finish. | |
643 | infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish. | |
644 | main.c: Lint. Lose have_inferior_p(). | |
645 | inferior.h (have_inferior_p): Remove, lint. | |
646 | (proceed_to_finish): Add flag to ask that all regs be saved | |
647 | by normal_stop, for the few commands that need it, speeding up | |
648 | serial I/O. Add comments to stop_registers. | |
649 | ||
650 | * remote-eb.c: Remove newline from breakpoint message we grep | |
651 | for. Never time out when running the user program. | |
652 | ||
653 | ||
654 | ||
655 | Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com) | |
656 | ||
657 | Roll in changes from vxgdb-5.0.1: | |
658 | ||
659 | * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON" | |
660 | symbol in its raw form, we are processing an unlinked ".o" file. | |
661 | See if the target environment has assigned it an address, using | |
662 | target_lookup_symbol (VxWorks does), and enter it into the symtab | |
663 | that way. | |
664 | ||
665 | * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual | |
666 | 68k versions for a simpler version that assumes zero FP at bottom. | |
667 | Fixes bug of truncated stack reports. | |
668 | ||
669 | * target.h (target_lookup_symbol): Define this routine's args | |
670 | and result, finally. | |
671 | ||
672 | * target.c (nosymbol): Default routine for target_lookup_symbol. | |
673 | (target_default): Default lookup_symbol and call_function too. | |
674 | (files_info): Only print has_all_memory warning if a non-dummy | |
675 | target follows. | |
676 | ||
677 | * remote-vx.c (vx_read_register, vx_convert_to_virtual, | |
678 | vx_convert_from_virtual): If target does not have floating point, | |
679 | zero register "values", and avoid doing cross-net conversions. | |
680 | (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors. | |
681 | (vx_open): Rearrange code that attaches to target and reads | |
682 | symbols for all loaded modules, to work if some of the modules | |
683 | are not accessible. Add symbol_stub() and add_symbol_stub() | |
684 | as callbacks from catch_errors(). Allow connect attempt to be | |
685 | interrupted painlessly with ^C (FIXME, there are still some bugs | |
686 | if the interrupt happens during symbol reading.). Print | |
687 | final message with puts_filtered, since symbol messages are | |
688 | now filtered too. | |
689 | ||
690 | Misc cleanup: | |
691 | ||
692 | * main.c (catch_errors): Only print errstring if non-null. | |
693 | (command_loop): Avoid an ioctl per command to test ISATTY. | |
694 | ||
695 | * remote-vx.c (net_load): make static; avoid sophomoric msg. | |
696 | (vx_xfer_memory): Return correct result! | |
697 | (vx_files_info): Indicate whether target has float or not. | |
698 | (vx_lookup_symbol): Complain, not error, if target gone. | |
699 | (vx_open): Print "Connected" msg before disabling immediate-quit. | |
700 | [FIXME: lookup_symbol and vx_open changes need testing.] | |
701 | ||
702 | target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h, | |
703 | tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add | |
704 | contributor lines and update copyrights to 1991. | |
705 | ||
706 | Changes from an attempted H-PUX host port: | |
707 | ||
708 | * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which | |
709 | defines PT_ATTACH and PT_DETACH but not PT_KILL. | |
710 | * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX. | |
711 | * remote-vx.c: include <sys/time.h> for HPUX. | |
712 | * hp300hpux-xdep.c (fetch_core_registers): Rewrite old | |
713 | "core_file_command" routine to BFD regime. May not work yet. | |
714 | ||
715 | Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb. | |
716 | ||
717 | * xgdb.c: Replace X10 version with some VJ version. | |
718 | (FIXME: Its copyright assignment is not on record.) | |
719 | * xgdb.c: Update include files to X11R4 (Xaw crud). | |
720 | (xgdb_display_source, create_text_widget): fix call to | |
721 | get_filename_and_charpos. Rewack source window stuff for X11R4 | |
722 | (gleaned from include files, and "nm's" of binary libraries, since | |
723 | I had no doc available). | |
724 | (append_selection, append_selection_word): Disable with FIXME | |
725 | since R4 changed interface here. | |
726 | (create_buttons): Add back the old set of buttons. | |
727 | (xgdb_create_window): Fix call to XtInitialize (&argc not argc). | |
728 | ||
729 | * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns. | |
730 | Roll VERSION to 3.94 (not yet final though). | |
731 | ||
732 | Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com) | |
733 | ||
734 | * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast, | |
735 | obstack_int_grow, obstack_int_grow_fast): Eliminate | |
736 | cast on left of assignment, which gives MIPS cc fits and is | |
737 | not Standard C. | |
738 | ||
739 | * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by | |
740 | F_ALIAS. Use printf, not fprintf, when not passing a file | |
741 | pointer... | |
742 | (compare_opcodes): Check that identical instructions have | |
743 | identical opcodes, complain otherwise. | |
744 | ||
745 | * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This | |
746 | was reported by Roland McGrath. | |
747 | (unimp): Only match if exactly zero instruction. (Roland) | |
748 | (branches and traps): Generate all variations of these | |
749 | instructions with macros, based on a single call that defines | |
750 | each condition name and its binary representation. | |
751 | (set): Turn on alias bit, to avoid test in sparc-pinsn.c. | |
752 | ||
753 | * valprint.c (val_print_fields): Take, and use, format parameter. | |
754 | This means that "p/x struct" again prints the elements in the | |
755 | desired format. Changed callers. | |
756 | ||
757 | * stack.c (frame_info): Use filtered output, and indicate wrap | |
758 | points. Remove kludgy formatting designed to avoid line wrap. | |
759 | ||
760 | * utils.c (wrap_here): If the line is already full (because | |
761 | we had printed a long indent or long wrapped string), do an | |
762 | immediate newline-and-indent. | |
763 | ||
764 | * m68k-pinsn.c (print_insn_arg): Bugfix from | |
765 | ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0' | |
766 | instruction is incorrectly disassembled as bkpt #8. | |
767 | ||
768 | * dbxread.c (end_psymtab): Bugfix from Peter Schauer | |
769 | <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a | |
770 | breakpoint in a *.y file gdb will say Reading in symbols for *.y... | |
771 | and then will dump core (sometimes). I traced it back to an | |
772 | uninitialized symfile_name in psymtab_to_symtab. | |
773 | (const_vol_complaint): Add quotes to message. | |
774 | (define_symbol): Only believe line number if gcc_compiled. | |
775 | Avoid allocating symbol if we will not return it. | |
776 | ||
777 | Add target strata support so that newly established targets go | |
778 | into their right place in the target stack (e.g. a new exec file | |
779 | doesn't wipe out the ability to access the running process). | |
780 | ||
781 | * target.h, core.c, exec.c, inftarg.c, remote-eb.c, | |
782 | remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum | |
783 | and initialize it properly in all the targets. | |
784 | ||
785 | * target.h: Document strata. Change return type of push_target. | |
786 | ||
787 | * target.c (nomemory): new function for dummy memory access. | |
788 | (tcomplain): Rename complain, now also used in symfile.c. | |
789 | (push_target): Push targets within strata. New return value shows | |
790 | whether new target is on top of stack or not. Always keep dummy | |
791 | target on stack. | |
792 | (target_files_info): Ignore dummy target. | |
793 | ||
794 | * core.c (core_open): Warn user, and skip accessing file, if the | |
795 | core target is not the topmost target in the stack. | |
796 | * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now | |
797 | already handled. | |
798 | ||
799 | * remote-vx.c: Remove vx_prepare_to_store from vxworks memory | |
800 | target_ops, it doesn't belong there since we have no regs there. | |
801 | Change name of target from machine => memory to clarify. | |
802 | ||
803 | Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com) | |
804 | ||
805 | * Freeze version 3.93 for release. | |
806 | ||
807 | * Makefile.dist: Handle vx-share and nindy-share subdirs | |
808 | properly when building gdb.tar.Z. | |
809 | ||
810 | * symtab.c: lint; add no_symtab_msg to consolidate the messages | |
811 | printed in various places, so I could change just one copy. | |
812 | ||
813 | * dbxread.c, coffread.c: Change references to bfd->iostream | |
814 | to cast to FILE *, now that BFD avoids needing types defined | |
815 | in other header files. | |
816 | ||
817 | Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com) | |
818 | ||
819 | * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c, | |
820 | infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c, | |
821 | sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint | |
822 | (actually gcc -Wall). | |
823 | ||
824 | * dbxread.c: Remove first_global_sym, last_global_sym, since | |
825 | they are never referenced. | |
826 | ||
827 | * defs.h (baud_rate): Declare. | |
828 | main.c: Define it, and add the -b option to set it. | |
829 | ||
830 | * gdb-int.texinfo: Add text on how to define a new host or target | |
831 | architecture, prompted by Per Bothner's questions about MIPS | |
832 | support. | |
833 | ||
834 | * gdb.texinfo: Document "complaints". Change doc of -q since | |
835 | gdb no longer prints the copyright and blurb if you specify a file | |
836 | name to be debugged (just like Emacs). Add doc for Nindy-specific | |
837 | command line flags for specifying target serial port and such. | |
838 | Update copyright to 1991. | |
839 | ||
840 | * gdbcore.h: Remove a large mass of now-useless crud, since BFD | |
841 | has taken over for us the job of ripping up executable files. The | |
842 | crud caused Per Bothner's port to not compile. | |
843 | ||
844 | * infrun.c (normal_stop): Avoid printing "Program exited | |
845 | normally" if we are in batch mode. This allows a GDB which | |
846 | executes a program on a target system, to behave like a Unix | |
847 | command (input from stdin, output to stdout, no extraneous | |
848 | output). | |
849 | ||
850 | * main.c (main): Allow additional machine-dependent command line | |
851 | options to be specified with the ADDITIONAL_OPTIONS, | |
852 | ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and | |
853 | ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent | |
854 | processing to occur just before the main loop with | |
855 | BEFORE_MAIN_LOOP_HOOK. | |
856 | (main): If a "core file" argument is specified, and it is not a | |
857 | core file, try it as a process ID to attach. | |
858 | (symbol_completion_function): Attempt to cope with | |
859 | "show screen-" TAB, not very successfully. This needs more work, | |
860 | FIXME. | |
861 | (batch_file): New function, returns whether we are reading | |
862 | commands from an interactive tty on stdin, or from somewhere else. | |
863 | Called by normal_stop since it doesn't get from_tty passed down | |
864 | to it like many commands do. | |
865 | ||
866 | * remote-nindy.c: Handle command line options for nindy | |
867 | connection. | |
868 | (nindy_before_main_loop): Prompt user for tty name if they | |
869 | don't specify it before getting to the interactive command loop. | |
870 | ||
871 | * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk, | |
872 | and -r command line options. Also add hook before main loop | |
873 | to make it easy to specify a tty. | |
874 | ||
875 | * TODO: More things to do, one done. | |
876 | ||
877 | Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com) | |
878 | ||
879 | * dbxread.c: Make complaint() calls pass pointer, not struct. | |
880 | Add complaints about badly formatted C++ type information | |
881 | (const/volatile indicator, and parse errors resulting in | |
882 | error_type). Fix C++ virtual member fn comment. | |
883 | (read_struct_type): Avoid bumping pointer if we got a parse | |
884 | error; this prevents our walking beyond the end of a string. | |
885 | Terminate loop on null char as well as semicolon. | |
886 | (process_one_symbol): Fix the LBRAC fix so that it uses the | |
887 | last previous SLINE, FUN, or SO record's PC address. C++ debug | |
888 | symbols did not have SLINE records in a useful order compared | |
889 | to the LBRAC records. | |
890 | (define_symbol): Handle "catch" records. | |
891 | ||
892 | * symtab.c (check_stub_type): Added new complain | |
893 | `stub_noname_complain' and added a consistency check to | |
894 | keep the debugger from crashing when finishing from an | |
895 | exception frame. A real fix will be needed later. | |
896 | ||
897 | Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com) | |
898 | ||
899 | * infcmd.c (attach_command): Make global. | |
900 | ||
901 | * Makefile.dist (REMOTE_OBS): Make these compile by default, | |
902 | but make them easy to comment out. Perhaps later they should | |
903 | be enabled by what CPU you configure for? FIXME. | |
904 | (VERSION): Roll to 3.93. | |
905 | (pinsn.o): Remove rule for obsolete file. | |
906 | (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly. | |
907 | ||
908 | Run down a problem that manifested by printing the wrong function | |
909 | name in stack traces of read_ofile_symtab. Turned out that the | |
910 | problem was the SunOS 4.1.1 (and previous) C compiler outputs | |
911 | the LBRAC symbol with an address in the *data* segment, which | |
912 | blew our binary search through the blocks. | |
913 | ||
914 | * dbxread.c: Use the complain() facility consistently to bitch | |
915 | about problems in the symbol file we are reading. | |
916 | (finish_block): Add code to check the nesting of the blocks; | |
917 | complain and Procrust them to fit if wrong. | |
918 | (make_blockvector): Check the order of the blocks, complain | |
919 | [but don't cope] if wrong. | |
920 | (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC | |
921 | symbols to be sure their PC value is greater than the last SLINE | |
922 | (line number) symbol we've seen, complaining and adopting the | |
923 | SLINE PC value if wrong. | |
924 | ||
925 | * symfile.h (struct complaint, complaint_root, complain, | |
926 | clear_complaints): Add. | |
927 | * symfile.c (complain, complaint_root, clear_complaints): Add | |
928 | facility to deal with non-fatal complaints and to regularize their | |
929 | suppression. | |
930 | (symbol_file_add): Clear complaint counters to allow new complaints. | |
931 | (initialize_symfile): Add 'set complaints' and 'show complaints'. | |
932 | ||
933 | * dbxread.c (dbx_symfile_read): Remember the address and size | |
934 | of the string table for the main symbol file, so we won't read it | |
935 | more than once. | |
936 | (dbx_psymtab_to_symtab): Fix the check for main symbol file, | |
937 | to avoid reading the string table yet again. Lint. | |
938 | (throughout): Improve filtered output, including word wrap. | |
939 | (read_range_type): Improve Bothner's fix to handle other types too. | |
940 | ||
941 | * utils.c: Improve line wrap implementation. Handle unlimited | |
942 | width by making chars_per_line unsigned. | |
943 | (puts_filtered): New, easy, function. | |
944 | ||
945 | * defs.h (puts_filtered): add. | |
946 | ||
947 | * mipsread.c (compare_symbols, sort_symtab): Remove these fns, | |
948 | call the identical sort_symtab_syms() in symfile.c instead. | |
949 | ||
950 | * expread.y: Suggest the `file' command rather than `symbol-file'. | |
951 | ||
952 | * command.h (enum var_types): Add zinteger for seroable | |
953 | unsigned integer. | |
954 | * command.c (do_setshow_command): Handle var_zinteger. Restructure | |
955 | nested if's into a switch. | |
956 | ||
957 | * breakpoint.c (bpstat_print): If bpstat "print" flag is not set, | |
958 | we did not stop because of a breakpoint (it must have been for | |
959 | some other reason, like a "stepi"), so don't print anything. | |
960 | ||
961 | * symtab.c: Include <sys/types.h> all the time. Now that BFD | |
962 | doesn't include <sys/types.h>, old SunOS's require it for | |
963 | <sys/stat.h>. | |
964 | ||
965 | Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu) | |
966 | ||
967 | A test port of gdb-3.92.6 to the Sony NEWS. | |
968 | ||
969 | * Makefile.dist | |
970 | Don't normally link in remote- or vx stuff. | |
971 | Some of it doesn't compile, and it wastes space for 99% of the users. | |
972 | Remove reference to no-longer-used HAVE_VPRINTF. | |
973 | Fixed BFD_DEP typo to BFD_DIR. | |
974 | * dbxread.c | |
975 | Fix cast in arg to bfd_h_getlong. | |
976 | Make char *prefix be const. | |
977 | Fix how certain range types are mapped into builtin unsigned int types. | |
978 | * infrun.c | |
979 | Remove 2 #includes. They cause errors (on Sony, at least), | |
980 | and aren't needed (they wern't in earlier versions). | |
981 | * printcmd.c | |
982 | print_address_symbolic should never demangle labels | |
983 | (since it prints *assembler-level* labels). | |
984 | ||
985 | [This was superseded by the change to printcmd below.] | |
986 | ||
987 | * utils.c | |
988 | Add some "volatile" return types to avoid warnings. | |
989 | If MISSING_VPRINTF add vprintf function and not just macro | |
990 | (since vprintf is used in printcmd.c). | |
991 | * valprint.c | |
992 | Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow. | |
993 | (The latter isn't grokked by some PCC-based compilers.) | |
994 | ||
995 | [This change is in abeyance, we prefer to fix obstack_ptr_grow.] | |
996 | ||
997 | Make chunk size of dont_print_obstack 32*4 instead of default 4096. | |
998 | * nindy-share/coffstrip.c | |
999 | Added some forward declarations (otherwise, gcc complains | |
1000 | about implicit extern redefined as static). | |
1001 | ||
1002 | Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com) | |
1003 | ||
1004 | Changes inspired by Per Bothner: | |
1005 | * printcmd.c (print_address_symbolic): Take additional parameter | |
1006 | specifying whether to demangle. | |
1007 | (print_address): Pass in asm_demangle to control demangling. | |
1008 | (print_address_demangle): New fn, takes explicit arg to control | |
1009 | demangling. | |
1010 | * utils.c: Add new vars demangle and asm_demangle, and let them | |
1011 | be set and shown. | |
1012 | (fputs_demangled): If !demangle, just print the argument. | |
1013 | (fprint_symbol): If !demangle, just print raw symbol. | |
1014 | * valprint.c (val_print): Call print_address_demangle rather than | |
1015 | print_address, to cause demangling to depend on the global | |
1016 | rather than assembler-level demangling setting. | |
1017 | * WHATS.NEW, gdb.texinfo: Document. | |
1018 | ||
1019 | * main.c (show_command): Show all settings if no arg. | |
1020 | (initialize_main): Make "info set" the same as naked "show". | |
1021 | * command.c (cmd_show_list): Handle prefix commands in the | |
1022 | list, and print the name of the setting as well as its English | |
1023 | description and value. | |
1024 | ||
1025 | Allow gdb functions to specify where a line should wrap if it | |
1026 | exceeds the size of a terminal line. Use it to make the output | |
1027 | prettier. | |
1028 | * utils.c (set_screen_width_command): New fn, mallocs a buffer | |
1029 | of the right size when screen width changes. | |
1030 | (set_screensize_command, screensize_info): Remove #if 0'd fns. | |
1031 | (wrap_here): New fn, indicates a point in the output where we | |
1032 | should wrap the line rather than just letting it overflow at a | |
1033 | random place. | |
1034 | (fputs_filtered): Implement wrapping. | |
1035 | (n_spaces): New fn, returns a pointer to N spaces. | |
1036 | (print_spaces_filtered): Use n_spaces. | |
1037 | * defs.h (n_spaces): Declare. | |
1038 | * stack.c (print_frame_info): Wrap with 4-space indent after | |
1039 | fn name and before filename and line number. | |
1040 | * printcmd.c (print_frame_args): Wrap with 4-space indent | |
1041 | before each argument name is printed. | |
1042 | * valprint.c (value_print): Wrap with no indentation before | |
1043 | each repetition. | |
1044 | (val_print_fields): Wrap with indentation relative to nesting | |
1045 | level before each field name. | |
1046 | (val_print): Wrap with nesting indentation before array elements. | |
1047 | * command.c (do_setshow_command): Avoid extra newlines, | |
1048 | wrap with 4-space indent around values printed, end with period. | |
1049 | * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document. | |
1050 | ||
1051 | * breakpoint.c (breakpoint_1): Implement addressprint for | |
1052 | "info breakpoints" display. Change file name and line number | |
1053 | format to " at file:nnn" rather than " (file line nnn)". | |
1054 | * gdb.texinfo: Document. | |
1055 | ||
1056 | ||
1057 | Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com) | |
1058 | ||
1059 | Frozen for gdb-3.92.6 release. | |
1060 | ||
1061 | README, WHATS.NEW: Update for 3.92.6 release. | |
1062 | ||
1063 | tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate | |
1064 | coffread.o from configs since it is now built by default. | |
1065 | tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux, | |
1066 | i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn, | |
1067 | pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o | |
1068 | from configs since it is now built by default. | |
1069 | ||
1070 | Makefile.dist: Update for release 3.92.6. Handle files that | |
1071 | have been moved to ../include, ../getopt, or ../bfd. Add | |
1072 | saber.suppress and tests directory. Add config.status to | |
1073 | the release (it will say "none"). | |
1074 | ||
1075 | coredep.c: Minor formatting fixes. | |
1076 | ||
1077 | These changes were made in early December but only checked in now: | |
1078 | * nindy-share/Onindy.c, nindy-share/coffstrip.c, | |
1079 | nindy-share/nindy.c: lint | |
1080 | * nindy-share/nindy.c (ninStopWhy): Don't byteswap the | |
1081 | register values coming back from the target; we store values | |
1082 | in target byte order everywhere. | |
1083 | ||
1084 | Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com) | |
1085 | ||
1086 | * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes. | |
1087 | ||
1088 | * valprint.c (cplus_val_print, val_print_fields): New functions, | |
1089 | which print C++ objects. They conspire to avoid printing a | |
1090 | virtual base class more than once, following all the twists and | |
1091 | turns of C++ virtual base rules. | |
1092 | (val_print): Call the above rather than do it by hand. | |
1093 | ||
1094 | * symfile.c (symbol_file_add): Only reset symfile_mtime for main | |
1095 | symbol file, not for added files like shared libs. This really | |
1096 | needs to be generalized to a timestamp per file. | |
1097 | ||
1098 | * core.c (cleanup_core): Avoid coredump if no core file. | |
1099 | ||
1100 | * config.gdb: Accept -host or -target in place of +host or | |
1101 | +target. | |
1102 | ||
1103 | * coffread.c (find_linenos): Avoid desupported BFD interface | |
1104 | to line numbers. We still read them manually rather than using | |
1105 | BFD's "generic" features. | |
1106 | ||
1107 | * gdbrc.tex, threecol.tex: Add GDB reference card and its | |
1108 | formatting code. | |
1109 | Makefile.dist: Add refcard to OTHERS list for creating tar files. | |
1110 | ||
1111 | * Makefile.dist: Eliminate use of $< in explicit targets. | |
1112 | ||
1113 | * readline/Makefile: Use $< rather than $*.c, which does not | |
1114 | include the VPATH in GNU Make. | |
1115 | ||
1116 | * tconfig/i960-bout, tconfig/i960-coff: These are identical | |
1117 | copies of tconfig/i960, added for global configuration | |
1118 | compatability. All i960 versions can read both coff and b.out. | |
1119 | ||
1120 | * tm-88k.h: Fix multiline macro that lacked \'s. Remove | |
1121 | COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled | |
1122 | automaticaly. | |
1123 | ||
1124 | * TODO: Think of more things to do. | |
1125 | ||
1126 | Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com) | |
1127 | ||
1128 | tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config | |
1129 | of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to | |
1130 | 64-bit float conversion. | |
1131 | ||
1132 | tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make | |
1133 | equivalent to sun?os4 so global config works. | |
1134 | ||
1135 | Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com) | |
1136 | ||
1137 | Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de> | |
1138 | ||
1139 | * main.c: Only declare linesize once; declare pagesize not at | |
1140 | all, since it is never used. | |
1141 | (main): Clear newly allocated line before it is used. | |
1142 | ||
1143 | Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint) | |
1144 | ||
1145 | Further stabilization for the Intel 960. | |
1146 | ||
1147 | * Makefile.dist: Parameterize the location of the "include" | |
1148 | and "bfd" directories, as well as "getopt". Add symfile.c. | |
1149 | Link in both dbxread and coffread. Fix up "make depend" to | |
1150 | rewack the locations of include, bfd, and getopt in its output. | |
1151 | ||
1152 | * README: Document moving include files, improve some of | |
1153 | the other doc. | |
1154 | ||
1155 | * coffread.c: Move common code out to symfile.c. Change | |
1156 | symbol_file_command style interface to use new *_symfile_init | |
1157 | and *_symfile_read interface under BFD. Use BFD internal | |
1158 | info to locate line table, symbols, etc. | |
1159 | ||
1160 | * core.c (core_fetch_registers): Rename to get_core_registers | |
1161 | to avoid confusion with fetch_core_registers. | |
1162 | (register_addr): Move to coredep.c, which is already machine | |
1163 | dependent. This leaves core.c pretty clean of dependencies. | |
1164 | ||
1165 | * coredep.c (register_addr): Accept this routine from core.c. | |
1166 | ||
1167 | * dbxread.c: Move common code (with coffread.c, etc) into new | |
1168 | symfile.c. Each psymtab now contains a pointer to the | |
1169 | format-dependent function that knows how to read it in. Make | |
1170 | some things static. | |
1171 | (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2. | |
1172 | (process_one_symbol): Add code to complain about a "compiler bug | |
1173 | we muzzle here", if we actually see it. | |
1174 | ||
1175 | * eval.c (evaluate_subexp): Insert missing "break" statements | |
1176 | in code that determines whether a variable is an lvalue in | |
1177 | memory, register, or whatever. I detected this via a compiler | |
1178 | bug in which it *almost* mashed out the whole switch statement. | |
1179 | ||
1180 | * gdb-int.texinfo: Add minor sections on configuring gdb for | |
1181 | release, and about the README file. | |
1182 | ||
1183 | * infcmd.c (registers_info): Fix formatting somewhat. Still | |
1184 | not as pretty as before, but it handles byte swapping. | |
1185 | ||
1186 | * remote-nindy.c: If data cache routines are interrupted while | |
1187 | waiting for the remote end, be sure that any uninitialized cache | |
1188 | blocks are on the free list, not on the valid list! | |
1189 | ||
1190 | * symfile.h: Flesh out this header file with all the various | |
1191 | routines and variables that have been merged in from dbxread.c | |
1192 | coffread.c, and symtab.c to symfile.c. | |
1193 | ||
1194 | * symfile.c: New file, containing code common to dbxread.c, | |
1195 | coffread.c, and some code from symtab.c. All generic code for | |
1196 | reading symbol files should be in here now. | |
1197 | (unrecord_misc_function): Remove unused function. | |
1198 | ||
1199 | * symtab.h: Remove file-reading things to symfile.h. | |
1200 | ||
1201 | * symtab.c: Remove file-reading things to symfile.c. | |
1202 | ||
1203 | * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL | |
1204 | to decode i960 fault types. | |
1205 | ||
1206 | * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c, | |
1207 | target.c: Change type of the "resume" function from int to void, | |
1208 | since its result was never used. | |
1209 | ||
1210 | Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint) | |
1211 | ||
1212 | * main.c: Replace "stupid" with "caution"; you now "set caution | |
1213 | on or off". | |
1214 | ||
1215 | * printcmd.c (print_scalar_formatted): Fix typo in 'g' format | |
1216 | ||
1217 | * infcmd.c (do_registers_info): Call val_print to deal with the | |
1218 | byte order of the registers being printed. FIXME, this makes | |
1219 | the formatting of the output uglier. | |
1220 | ||
1221 | * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is | |
1222 | defined, call it for signals the debugger doesn't itself use. | |
1223 | The i960 uses this for more detailed fault information. | |
1224 | ||
1225 | * remote.c (remote_open): If arg is null, print help rather than | |
1226 | dumping core. | |
1227 | ||
1228 | * sparc-xdep.c (register_valid): Avoid declaring size, since | |
1229 | various modules will think of various sizes depending on the | |
1230 | architecture of their tm-file. FIXME, we need protection against | |
1231 | actually entering one of those modules, which would clobber | |
1232 | storage if not for the target architecture compiled into gdb. | |
1233 | ||
1234 | * stack.c (up_command, down_command): Always print the frame | |
1235 | you arrive at. | |
1236 | (up_silently_command, down_silently_command): New commands | |
1237 | for use in scripts. | |
1238 | ||
1239 | * i960-pinsn.c (reg), i960-tdep.c: Lint. | |
1240 | ||
1241 | * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes | |
1242 | more parameters than it used to. | |
1243 | ||
1244 | * findvar.c (registers): Increase slop to 256 bytes, which should | |
1245 | protect us against even most RISC machines with large register | |
1246 | sets. | |
1247 | (locate_var_value): Move declaration inside related ifdef. | |
1248 | ||
1249 | * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP | |
1250 | throughout, to avoid throwing away buffered input from the board. | |
1251 | (nindy_wait): Supply_register takes addr_of_value, not value. | |
1252 | (i960_print_fault): Renamed from i80960_fault. | |
1253 | (nindy_fetch_registers): Avoid have_regs stuff, just get them. | |
1254 | (nindy_store_registers): Avoid regs_changed stuff, just stuff | |
1255 | them. | |
1256 | (nindy_create_inferior): Don't bother to write PC_REGNUM since | |
1257 | we can set the PC in the call to proceed(). Unpush nindy_ops | |
1258 | before pushing it on top, to avoid message to user. Eliminate | |
1259 | commentary from Unix machines that just misleads here. | |
1260 | (reset_command): Fix error message to suggest target command. | |
1261 | ||
1262 | Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint) | |
1263 | ||
1264 | Release 3.92.5 as frozen. | |
1265 | ||
1266 | Stabilize the merged release...with help from lint, Saber C, | |
1267 | gcc -W, etc. | |
1268 | ||
1269 | Everywhere: Add include files needed to declare return types | |
1270 | of functions called. | |
1271 | ||
1272 | * gdb.texinfo: Roland Pesch is documenting gdb, glory be! | |
1273 | ||
1274 | * breakpoint.h: Add undeclared breakpoint functions, and some | |
1275 | functions for display handling since I couldn't think of a better | |
1276 | .h to put them in. | |
1277 | ||
1278 | * breakpoint.c (insert_breakpoints): Make code for disabling | |
1279 | shared library bkpts more likely to work. It's used when we | |
1280 | rerun a program and stop before the shared library has been | |
1281 | mapped in. | |
1282 | (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int, | |
1283 | cast from pointer, so it squeezes through catch_errors. | |
1284 | (bpstat_stop_status): Fix logic broken some time ago. We now | |
1285 | always create a bpstat if the stop address matches a breakpoint, | |
1286 | even if we don't stop there -- just like the old code used to do | |
1287 | before I got my fingers into it (sigh). | |
1288 | (breakpoint_1): Print "ignore count" after "stop only if" | |
1289 | condition, since that's how it actually works. | |
1290 | (mention): Handle watchpoints as well as breakpoints. | |
1291 | (watch_command): use set_raw_breakpoint and mention to do most | |
1292 | of the work (and initialize all the fields!). Only pass one | |
1293 | arg to parse_c_expression, since that's all it takes. | |
1294 | ||
1295 | * command.c (not_just_help_class_command): Rename arg to args | |
1296 | since we ignore "unused argument" warnings on vars named "args". | |
1297 | inflow.c (child_terminal_info): ditto. | |
1298 | infptrace.c (kill_inferior): ditto | |
1299 | main.c (catch_errors, version_info, quit_command, pwd_command, | |
1300 | source_command, dump_me_command, editing_info, | |
1301 | set_history_size_command, set_history, show_history, | |
1302 | set_verbose): ditto | |
1303 | stack.c (locals_info): ditto | |
1304 | target.c (target_files_info): ditto | |
1305 | valprint.c (set_input_radix, set_output_radix): ditto | |
1306 | ||
1307 | * core.c: Remove old variables for handling core and exec file | |
1308 | sections (data_start, data_end, stack_start, stack_end, | |
1309 | reg_stack_start, reg_stack_end, reg_stack_offset, text_start, | |
1310 | text_end, exec_data_start, exec_data_end, text_offset, | |
1311 | exec_data_offset, data_offset, stack_offset). They're | |
1312 | superseded the more general build_section_table and | |
1313 | xfer_memory. | |
1314 | (get_exec_file): Mention the `file' command. | |
1315 | (read_memory_check): Rename to memory_error, and only call it | |
1316 | in the case of an actual error. | |
1317 | (read_memory, write_memory): call memory_error. | |
1318 | (core_fetch_registers): Register section name is ".reg". | |
1319 | ||
1320 | coredep.c: Remove a bunch of crud now that all this file does | |
1321 | is pull the registers out of a core file. | |
1322 | (fetch_core_registers): Rewrite to actually work, I hope. | |
1323 | ||
1324 | dbxread.c: Use a.out.gnu.h, not system a.out, now. | |
1325 | Replace index() with strchr(). Remove all the pre-BFD macro | |
1326 | definitions for accessing the symbol file. | |
1327 | (struct dbx_symfile_info): Encapsulate the information that | |
1328 | dbx_symfile_init needs to pass to dbx_symfile_read in this | |
1329 | struct. | |
1330 | ||
1331 | (dbx_new_init, dbx_symfile_init, dbx_symfile_read, | |
1332 | dbx_symfile_discard): Rearrange symbol file reading to divide | |
1333 | the format-specific part from the format-independent part, | |
1334 | leaving the format-independent part such as file name expansion | |
1335 | and opening in symtab.c. This replaces | |
1336 | partial_symbol_file_open and partial_symbol_file_read. | |
1337 | Symbol_file_read, add_file, add_file_target_command, | |
1338 | add_file_addr_command move to symtab.c. Pass an explicit | |
1339 | "mainline" flag for when reading the main symbol table, rather | |
1340 | than relying on the offset address to be zero or nonzero. | |
1341 | ||
1342 | (dbx_symfile_read): Don't allow void *'s to be printed as | |
1343 | typedefs. | |
1344 | (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols. | |
1345 | (ADD_PSYMBOL_TO_LIST): Make the "function call rather than | |
1346 | macro" debug version really work. | |
1347 | (read_dbx_symtab): Remove unref'd parameter inclink. | |
1348 | Avoid swapping N_SLINE symbols, for speed. | |
1349 | Merge N_TEXT!N_EXT case with the other external symbol | |
1350 | definitions' case. Add comments. | |
1351 | (start_psymtab): Allocate the symfile name in the psymtab on | |
1352 | the psymbol_obstack, rather than using the caller's storage. | |
1353 | (end_psymtab): Only allocate a dependencies list if there are | |
1354 | more than zero. | |
1355 | (psymtab_to_symtab_2): Use BFD when reopening file to read | |
1356 | its symbols for real. | |
1357 | (read_struct_type): Add FIXME comments where it needs work | |
1358 | for C++ bogosity. | |
1359 | (read_huge_number): Add FIXME about overflows. | |
1360 | (read_range_type): Add FIXME about comparing a long to 1<<32. | |
1361 | ||
1362 | * coffread.c: Minor changes to move things closer to the new | |
1363 | regime with symtab.c and dbxread.c Major work is still needed | |
1364 | here. | |
1365 | ||
1366 | * exec.c (exec_file_command): Remove old variables (see core.c | |
1367 | above). | |
1368 | (xfer_memory): If memory transfer is right at the end of a | |
1369 | section, don't lose. | |
1370 | ||
1371 | * findvar.c (get_saved_register): If value is in a real | |
1372 | register, LVAL is lval_register, not lval_memory. | |
1373 | ||
1374 | frame.h: Declare print_sel_frame and record_selected_frame. | |
1375 | ||
1376 | gdb-int.texinfo: New file, for GDB internals documentation. | |
1377 | Very simple, unformatted doc of cleanups is there for now. | |
1378 | ||
1379 | gdbcore.h: Remove obsolete variables that described a.out | |
1380 | section addresses and offsets. (See core.c above.) | |
1381 | Declare fetch_core_registers and registers_fetched. | |
1382 | ||
1383 | getopt.c: Declare char *alloca(); even on SPARC. | |
1384 | ||
1385 | infcmd.c (run_command): Call target_kill rather than | |
1386 | kill_inferior. | |
1387 | (step_command, next_command, stepi_command, nexti_command): | |
1388 | Declare from_tty parameter even though we don't use it. | |
1389 | (run_stack_dummy): argument BUFFER is a char array, not | |
1390 | a pointer to REGISTER_TYPE. | |
1391 | (finish_command): using_struct_return needed a value *, | |
1392 | not a struct symbol *. | |
1393 | ||
1394 | * infptrace.c (child_xfer_memory): To avoid dependency on | |
1395 | where sections are in memory, try PT_WRITE_D and if that fails, | |
1396 | try PT_WRITE_I. Most Unixes don't care which you use. | |
1397 | ||
1398 | * infrun.c (step_resume_break_shadow): Change to array to | |
1399 | match other breakpoint shadow storage. | |
1400 | (clear_proceed_status): Pass address of bpstat to | |
1401 | bpstat_clear, not the bpstat itself. | |
1402 | (child_create_inferior): FIXME comment about if the child | |
1403 | exits. | |
1404 | (start_inferior): Remove old function. | |
1405 | (child_open): Use target_kill rather than kill_inferior. | |
1406 | (wait_for_inferior): Ditto. | |
1407 | (insert_step_breakpoint, remote_step_breakpoint): Use | |
1408 | new step_resume_break_shadow. | |
1409 | ||
1410 | * inftarg.c (child_wait): If all child processes die, | |
1411 | pretend that the one being waited for exited with signal 42. | |
1412 | ||
1413 | * main.c (command_line_input): When scanning for comments, | |
1414 | don't coredump on unclosed quotes. | |
1415 | (quit_command): Use target_kill rther than kill_inferior. | |
1416 | (_initialize_main): Rename class_user from "user" to | |
1417 | "user-defined". | |
1418 | ||
1419 | * printcmd.c (print_command_1): Initialize "fmt" if no format | |
1420 | is specified by the user. | |
1421 | (print_frame_args): Only add to args_printed if we are | |
1422 | actually fetching args from the stack (avoiding undefined | |
1423 | arg_size). | |
1424 | (_initialize_printcmd): Remove bogus \{ from string. | |
1425 | ||
1426 | * remote-eb.c (eb_open): Avoid coredump on no argument. | |
1427 | ||
1428 | * remote-nindy.c: Bring out of Intel environment into new | |
1429 | target environment. Remove all conditional compilation on | |
1430 | I80960. Massive hacking throughout. | |
1431 | (nindy_xfer_inferior_memory): New routine stolen from | |
1432 | infptrace.c. | |
1433 | (nindy_create_inferior): New routine pieced together, probably | |
1434 | not quite working yet. | |
1435 | (nindy_ops): New target_ops struct for nindy. | |
1436 | ||
1437 | * remote-vx.c: Use write_memory rather than target_write_memory | |
1438 | to get error checking. | |
1439 | (vx_add_file_command, vx_open): Use symbol_file_add rather than | |
1440 | add_file. | |
1441 | (vx_create_inferior): Use target_terminal_ours... | |
1442 | ||
1443 | * signame.c (_initialize_signame): Always initialize, since | |
1444 | we need the table for things other than psignal. | |
1445 | ||
1446 | * solib.c (solib_add): Use symbol_file_add, not add_file. | |
1447 | (solib_address): Return boolean result rather than struct | |
1448 | pointer which nobody else knows the type of. | |
1449 | ||
1450 | * sparc-tdep.c, valops.c: Use write_memory rather than | |
1451 | target_write_memory, to get error checking. | |
1452 | ||
1453 | * stack.c (locals_info, catch_info, args_info, | |
1454 | get_selected_block, frame_command, up_command): Use | |
1455 | target_has_stack, rather than have_inferior_p or | |
1456 | have_core_file_p. | |
1457 | ||
1458 | * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime. | |
1459 | ||
1460 | * symfile.h: New file, defining the interface between the | |
1461 | generic and object-file-specific symbol reading code. | |
1462 | ||
1463 | * symtab.c: Move generic symbol-reading interface to symtab.c, | |
1464 | from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns | |
1465 | table to map BFD targets to symbol-reading modules in GDB. | |
1466 | Change index to strchr. | |
1467 | (lookup_struct_elt_type): Use error() rather than hand-made | |
1468 | simulations thereof. | |
1469 | (lookup_partial_symbol): Speedup slightly when length == 0. | |
1470 | (symbol_file_add): New function. | |
1471 | (symbol_file_command): Call it. | |
1472 | (symfile_open, symfile_init): New function. | |
1473 | (add_file_target_command, add_file_addr_command): moved from | |
1474 | dbxread.c. | |
1475 | ||
1476 | * target.c (target_command): use target_kill. | |
1477 | ||
1478 | * target.h (target_files_info): Don't declare, never called | |
1479 | from outside. | |
1480 | ||
1481 | * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include | |
1482 | files to determine stack end address. | |
1483 | ||
1484 | * valarith.c (value_x_binop, value_x_unop): Change error message | |
1485 | to be more useful. Pass proper argument to value_struct_elt. | |
1486 | ||
1487 | * valops.c (value_assign): FIXME comment that long long | |
1488 | bitfields will break here. | |
1489 | ||
1490 | * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c. | |
1491 | Update `make saber_gdb' to work better. | |
1492 | ||
1493 | * TODO: A woman's work is never done. | |
1494 | ||
1495 | * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c, | |
1496 | main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c, | |
1497 | remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c, | |
1498 | sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h | |
1499 | target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c, | |
1500 | valops.c, valprint.c, exec.c: Lint. | |
1501 | ||
1502 | ||
1503 | Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com) | |
1504 | ||
1505 | Continuing Intel 960 port merge of GDB. | |
1506 | ||
1507 | * Makefile.dist: Merge i960 "nindy-share" files. Rename | |
1508 | malloc.h to gmalloc.h to avoid name conflicts in /usr/include. | |
1509 | Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c. | |
1510 | Wack over "make depend" so it handles files in subdirectories | |
1511 | vx-share, nindy-share, bfd, and in the current directory. | |
1512 | ||
1513 | * blockframe.c (get_prev_frame_info): Remove fatal error | |
1514 | if stack not defined. | |
1515 | ||
1516 | * core.c (core_open, core_detach): New functions that handle | |
1517 | the old "core-file" command as "target core" and "detach" instead. | |
1518 | (core_file_command): Call them. | |
1519 | (core_xfer_memory): Use common routine xfer_memory. | |
1520 | ||
1521 | * dbxread.c: Include a.out.gnu.h, not system a.out.h. | |
1522 | dbxread now uses bfd for everything but symbol reading itself. | |
1523 | BFD internals are used to drag out the relevant file offsets. | |
1524 | (partial_symbol_file_open): Change args all around for BFD. | |
1525 | ||
1526 | * symtab.c: Rename "value" to "val" everywhere, so we can | |
1527 | #include "value.h". | |
1528 | (symbol_file_command): New command, moved from dbxread.c | |
1529 | and coffread.c. It uses BFD to read the file, then vectors | |
1530 | based on its type, to dbx or coff symbol readers. | |
1531 | * symtab.h: Extern a few vars for symbol_file_command. | |
1532 | ||
1533 | * target.h: Breakpoint takes a char * save area, not a char **. | |
1534 | ||
1535 | * valprint.c (val_print): When unpacking bitfields, offset | |
1536 | the address in gdb of the value, if it is declared with a shorter | |
1537 | type. Remove the last "runtime kludge test" of host byte order. | |
1538 | ||
1539 | * utils.c: Remove old my_bfd_read routine. | |
1540 | ||
1541 | * stack.c (frame_info): Use target_has_stack. Print program counter | |
1542 | register's actual name rather than "pc", since it's called the | |
1543 | "ip" (instruction pointer) on the i960 (sigh). | |
1544 | ||
1545 | * target.c (target_command): Add command for selecting a target | |
1546 | type and calling its open routine. This is used for initiating | |
1547 | communication with a particular target, in a generic way. | |
1548 | ||
1549 | * tm-i960.h: Update for modern gdb. Remove semicolons from | |
1550 | various macros. Handle reading struct return convention, and | |
1551 | error-out attempts to return structs with the "return" command. | |
1552 | Be sure gdb doesn't think we know how to call functions in the | |
1553 | inferior. | |
1554 | ||
1555 | * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS | |
1556 | to i960_xxx in lower case. | |
1557 | (arg_address): Circumvent errors due to LOC_ARG_BLOCK | |
1558 | not being defined yet. | |
1559 | ||
1560 | * remote.c (remote_open): Call start_remote to initialize | |
1561 | wait_for_inferior during open. | |
1562 | (remote_xfer_inferior_memory): Return length written rather | |
1563 | than errno value. | |
1564 | ||
1565 | * remote-vx.c (target_command -> vx_open): Use new generic | |
1566 | target command. | |
1567 | * remote-eb.c, inftarg.c, exec.c: ditto. | |
1568 | ||
1569 | * infrun.c: Fix comments. | |
1570 | (attach_program -> child_open): Use new generic target command. | |
1571 | (wait_for_inferior): Clear saved register values before target_wait, | |
1572 | so target_wait can set some of them if convenient. | |
1573 | ||
1574 | * infptrace.c (fetch_inferior_registers, store_inferior_registers): | |
1575 | Return success indicator, not void. | |

1577 | overwrite it anyway. | |
1578 | ||
1579 | * infcmd.c (attach_command): Use new generic target open routine. | |
1580 | (_initialize_infcmd): Update doc on attach and detach commands. | |

1586 | (write_register): Convert byte order on the way out. | |
1587 | ||
1588 | * exec.c (file_command): Add. | |
1589 | (add_to_section_table, exec_command): Use new bfd_map_over_sections. | |
1590 | (xfer_memory): Common function between core_xfer_memory and | |

1600 | Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com) | |
1601 | ||
1602 | Merge Intel 960 port of gdb, continuing... | |
1603 | ||
1604 | * dbxread.c (partial_symbol_file_open, partial_symbol_file_read, | |
1605 | symbol_file_command): Pass from_tty arg to hush 'em up. | |
1606 | ||
1607 | * coffread.c (symbol_file_command): Avoid output if from_tty != 1. | |
1608 | Add magic numbers for 960 COFF format. | |
1609 | ||
1610 | Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com) | |
1611 | ||
1612 | Merge Intel 960 port of gdb, from Intel "1.2" release. | |
1613 | ||
1614 | CHANGE_LOG entries from their port, which was based on | |
1615 | gdb+-2.8.0: | |
1616 | ||
1617 | Thu Sep 6 11:02:22 PDT 1990 | |
1618 | Remove temp file if download is interrupted. | |
1619 | ||
1620 | Wed Aug 1 09:08:33 PDT 1990 | |
1621 | Now uses binary protocol to talk to NINDY. | |
1622 | Old hex protocol (NINDY 2.13 and older) supported with -O switch. | |
1623 | Times out after 5 seconds when trying to talk to NINDY. | |
1624 | ||
1625 | Tue May 29 12:54:49 PDT 1990 | |
1626 | Added variable baud rate (-b switch). | |
1627 | Source code reorganization. | |
1628 | ||
1629 | Thu Apr 26 11:09:55 PDT 1990 | |
1630 | More cleanup of batch mode; specifically, execute "-s", "-e", and | |
1631 | "-se" switches as soon as they are encountered on the invocation line. | |
1632 | ||
1633 | Fri Apr 20 13:47:15 PDT 1990 | |
1634 | Add -brk switch. | |
1635 | ||
1636 | Thu Apr 19 09:54:28 PDT 1990 | |
1637 | Add 'reset' command. | |
1638 | ||
1639 | Wed Apr 18 09:48:07 PDT 1990 | |
1640 | After opening remote tty, wait for 1 second to go by without input | |
1641 | from it before trying to talk to NINDY (fixes problems with the | |
1642 | Heurikon HK80/V960E). | |
1643 | ||
1644 | Mon Apr 4 16:33:05 PDT 1990 | |
1645 | Some output was not being suppressed in 'batch' mode. | |
1646 | ||
1647 | Thu Mar 22 15:31:11 PST 1990 | |
1648 | Ask user if old symbol table should be deleted when new file is | |
1649 | downloaded. | |
1650 | ||
1651 | Allow user to run a program downloaded before gdb960 was brought up. | |
1652 | ||
1653 | Correct "exec-file" help message for i80960 context. | |
1654 | ||
1655 | Correct bug in calculating user space address: could occasionally | |
1656 | corrupt user program. | |
1657 | ||
1658 | Make sure to zero low-order bits in rip's because of bug in 960CA | |
1659 | A-step part: could cause operation faults when "next"ing across | |
1660 | a function call. | |
1661 | ||
1662 | Correct bug that made it impossible to get source line numbers for | |
1663 | code loaded at addresses higher than 0x7fffffff. | |
1664 | ||
1665 | Wed Jan 10 12:43:22 PST 1990 | |
1666 | Open remote tty for exclusive use. | |
1667 | ||
1668 | Fri Jan 5 12:14:42 PST 1990 | |
1669 | Correct disassembly (CA manual was right after all): | |
1670 | opcode for sysctl is 0x659 | |
1671 | ||
1672 | Mon Oct 23 12:03:04 PDT 1989 | |
1673 | Use G960BASE and G960BIN environment variables to find 'sx' utility. | |
1674 | ||
1675 | Mon Oct 16 14:15:09 PDT 1989 | |
1676 | "sfr0"-"sfr31" should have been named "sf0"-"sf31" | |
1677 | ||
1678 | Mon Oct 2 15:56:31 PDT 1989 | |
1679 | ||
1680 | Added 960CA disassembly support. | |
1681 | ||
1682 | To simplify maintenance: | |
1683 | - eliminated use of symblic links on pinsn.c: use i960-pinsn.c | |
1684 | directly instead. | |
1685 | - eliminated opcode.h: incorporates tables into i960-pinsn.c | |
1686 | - moved 960-specific routines from i960-pinsn.c to i960-md.c | |
1687 | - made disassembly interface identical to that in gdmp960. | |
1688 | ||
1689 | ||
1690 | ||
1691 | Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint) | |
1692 | ||
1693 | * target.h: Allow targets to stack. Add target_has_memory, | |
1694 | _registers, etc. Restructure memory access and "info files" | |
1695 | to walk the target stack. | |
1696 | * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c, | |
1697 | target.c: Change tables to match target.h. | |
1698 | * inflow.c (child_mourn_inferior): pop child_ops. | |
1699 | (generic_mourn_inferior): Use new has_stack flag. | |
1700 | * infptrace.c (child_xfer_memory): New memory regime. | |
1701 | * inftarg.c (child_files_info): New "info files" regime. | |
1702 | * remote-eb.c: New memory regime, new info files. | |
1703 | * remote-vx.c: New memory regime, new info files. Now use | |
1704 | separate targets for VxWorks attachment to machine, and | |
1705 | actually running a process under VxWorks, since one has | |
1706 | stack & execution & regs and the other doesn't. | |
1707 | * remote.c: New memory regime, new info files. | |
1708 | * sparc-xdep.c (fetch_core-registers): New memory regime. | |
1709 | * target.c: New routines and support for stacked targets, | |
1710 | new memory regime, new info files regime. | |
1711 | ||
1712 | ||
1713 | Generalize section handling for an arbitrary number of sections, | |
1714 | including use of the new BFD (binary file) library. | |
1715 | * gdbcore.h: Add struct section_table. | |
1716 | * exec.c (build_section_table): Iterate all sections and | |
1717 | record what gdb needs to know about them. | |
1718 | (exec_command): Use it. | |
1719 | (exec_xfer_memory): Use the table. | |
1720 | (exec_files_info): Print the table. | |
1721 | * core.c (core_file_command, core_xfer_memory, core_files_info): | |
1722 | Likewise. | |
1723 | * source.c (find_source_lines): Use bfd_get_mtime. | |
1724 | * dbxread.c: Quick changes to make it compile with new BFD. | |
1725 | * utils.c (error): Avoid using bfd_error in generic routines. | |
1726 | ||
1727 | * core.c (core_fetch_registers): Get from the ".regs" section of | |
1728 | the BFD core file. | |
1729 | * sparc-xdep.c (fetch_core_registers): Use the .regs info. | |
1730 | ||
1731 | * inferior.h (attach_flag): Export. | |
1732 | * infcmd.c (run_command): use new target_create_inferior. | |
1733 | * infrun.c (child_create_inferior): Don't return result. | |
1734 | * Makefile.dist (VERSION): 3.91.4. | |
1735 | ||
1736 | Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint) | |
1737 | ||
1738 | * breakpoint.c (bpstat_num): Handle breakpoints which have | |
1739 | since been deleted, such as temporary breakpoints. | |
1740 | infcmd.c (program_info): ditto. | |
1741 | ||
1742 | * core.c (core_file_command): Display the frame where the core | |
1743 | dump occurred. | |
1744 | ||
1745 | * main.c: lint. | |
1746 | ||
1747 | * remote-vx.c (target_command): Merge in target command from | |
1748 | targ-vx.c. A few other cleanups. | |
1749 | ||
1750 | * TODO, Projects: Lots more stuff to do... | |
1751 | ||
1752 | Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint) | |
1753 | ||
1754 | Massive changes to wall off the remote-debugging interface | |
1755 | behind a function vector. The port to handle VxWorks targets | |
1756 | is also part of this. | |
1757 | ||
1758 | All files: Replace references to renamed functions, | |
1759 | remove references to remote_debugging, remove references to | |
1760 | have_include_file, have_core_file in favor of target_has_stack, | |
1761 | target_has_memory, etc. | |
1762 | ||
1763 | * Modularize the breakpoint interface. | |
1764 | breakpoint.h (BREAKPOINT_MAX): New define sets max length of | |
1765 | a breakpoint instruction. | |
1766 | breakpoint.c: struct breakpoint's shadow_contents now sized as | |
1767 | BREAKPOINT_MAX. | |
1768 | (insert_breakpoints): Vector to target to install breakpoints. | |
1769 | (remove_breakpoints): Vector to target here too. | |
1770 | Remove REMOTE_SA_SPARC kludges and other remote_debugging. | |
1771 | sparc-tdep.c (single_step): Use new breakpoint interface for | |
1772 | the single-step breakpoints. | |
1773 | mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint): | |
1774 | New file, contains routines to insert and remove breakpoints by | |
1775 | reading out the old contents and later replacing them. This is | |
1776 | how ptrace breakpoints work, and many remote systems as well. | |
1777 | ||
1778 | * tm-vxworks68.h: New config file, overrides a few things for | |
1779 | Wind River's preferences. | |
1780 | ||
1781 | * target.h: New file, for transfer vector used to talk to the | |
1782 | inferior (child, attached, core, exec, remote, etc). All accesses | |
1783 | to the thing being debugged should come through these vectors. | |
1784 | target.c: New file, routines to handle transfer vector. | |
1785 | (various files): Add transfer vectors XXX_ops for the various | |
1786 | targets and pseudo-targets (core files, etc) we support. | |
1787 | ||
1788 | * breakpoint.c (bpstat_stop_status): Further explorations of | |
1789 | watchpoints and why things don't work all the time. | |
1790 | (bpstat_alloc): New fn to allocate a bpstat and chain it. | |
1791 | ||
1792 | * config.gdb: Only add "source ${srcdir}/.gdbinit" to | |
1793 | the local gdbinit if it doesn't already have it. | |
1794 | ||
1795 | * core.c (core_ops): add and install. | |
1796 | Allow core debugging without exec file. | |
1797 | ||
1798 | * dbxread.c (free_and_init_header_files): Merge two fns. | |
1799 | (end_symtab): Free named symbol table when a new version comes in. | |
1800 | (read_dbx_symtab): Relocate all kinds of symbols with base | |
1801 | address. First step toward handling different text, data, bss | |
1802 | reloc. | |
1803 | (add_file_addr_command): Renamed add_file_command. | |
1804 | (add_file_command): Vector to remote handler. | |
1805 | Add "load" as an alias for "add-file" command. | |
1806 | ||
1807 | * defs.h: Allow "volatile" to be used in non-ANSI; use it for | |
1808 | non-returning functions. | |
1809 | ||
1810 | * exec.c: Add exec_ops, and push it as a target when an exec | |
1811 | file is specified. | |
1812 | ||
1813 | * infcmd.c (run_command): Pass executable file name and arg list | |
1814 | separately when starting an inferior. Permit "run" when no exec | |
1815 | file is specified, for VxWorks. | |
1816 | (detach_command): Move to child_detach in inftarg.c. | |
1817 | ||
1818 | * inftarg.c: New file. Unix-child-specific routines, and the | |
1819 | child_ops structure. | |
1820 | ||
1821 | * inferior.h (registers): Export "registers" as the way for | |
1822 | target dependent register handlers to find gdb's local copy of | |
1823 | the registers. Rename "stop_after_attach" to "stop_soon_quietly" | |
1824 | since it is now used by places that want wait_for_inferior to | |
1825 | handle the grunge but want to see every trap from the inferior. | |
1826 | ||
1827 | * inflow.c (create_inferior): Pull out, and merge into infrun.c. | |
1828 | Eliminate remote_debugging hooks in terminal handling. | |
1829 | ||
1830 | * infrun.c: Replace start_inferior with child_create_inferior. | |
1831 | Move all the hair of Unix shells and ptrace idiosyncracies into | |
1832 | child_create_inferior, so remote handlers don't have to deal. | |
1833 | Remove running_in_shell. Rename stop_after_attach to | |
1834 | stop_soon_quietly, and use it in a few other places where we want | |
1835 | to just call wait_for_inferior and get control back on the first | |
1836 | trap. trap_expected now never takes a value > 1. | |
1837 | (init_wait_for_inferior): Initialize static vars when a new | |
1838 | process is created. | |
1839 | ||
1840 | main.c (gdbinit): Add new hook for .gdbinit file name, let | |
1841 | it be overridden by config files as GDBINIT_FILENAME. | |
1842 | (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt. | |
1843 | Both of these are used for VxWorks gdb. | |
1844 | ||
1845 | mcheck.c: rename include file "gmalloc.c" to avoid problems | |
1846 | with system include file "malloc.c". | |
1847 | ||
1848 | param-no-tm.h: New include file, same as param.h but does not | |
1849 | include the default "tm.h" file. This is used in files where | |
1850 | the target is known, e.g. remote-eb.c or sparc-xdep.c. | |
1851 | ||
1852 | param.h: Now just a shell that includes tm.h and param-no-tm.h. | |
1853 | ||
1854 | remote-vx.c: New file, VxWorks remote debugging support. Uses | |
1855 | RPC routines that are shared with the target system, in directory | |
1856 | ${srcdir}/vx-share. | |
1857 | ||
1858 | remote.c: Vectorize remote interface. | |
1859 | ||
1860 | source.c: Globalize source_path, and make an alias "l" for "list" | |
1861 | since we now have the "load" command. | |
1862 | ||
1863 | sparc-xdep.c: Use new param-no-tm.h. | |
1864 | ||
1865 | symmisc.c (free_named_symtab): Add new function from Wind River. | |
1866 | However, ifdef it out for now while we think about what it should | |
1867 | really be doing. | |
1868 | ||
1869 | tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move | |
1870 | PREPARE_TO_STORE to | |
1871 | the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since | |
1872 | non-Unix-children handle this with their own code in the target | |
1873 | transfer vector. | |
1874 | ||
1875 | Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to | |
1876 | source and target lists. Add vx-share to default list of include | |
1877 | directories. Add new files to src and target lists: mem-break, | |
1878 | target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the | |
1879 | ${srcdir} versions of munch and createtags are used. | |
1880 | ||
1881 | * valops.c (find_function_addr): Split out of call_function. | |
1882 | (call_function_by_hand): Rename call_function; this function | |
1883 | calls functions in the target by laboriously patching the target | |
1884 | word-by-word with the right stack, args, regs, etc. | |
1885 | ||
1886 | ||
1887 | Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint) | |
1888 | ||
1889 | Handle AMD 29000 a bit better. | |
1890 | ||
1891 | * remote-eb.c (readchar): Mask received char log to make it readable. | |
1892 | (remote_start): Pass arguments down to executing program. | |
1893 | Make startaddr unsigned. | |
1894 | infrun.c (start_inferior): Accept args, pass them to | |
1895 | remote_start. | |
1896 | infcmd.c (run_command): Pass args down to start_inferior. | |
1897 | ||
1898 | * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying | |
1899 | the target object file format. | |
1900 | tm-29k.h: Pay heed to COFF_ENCAPSULATE. | |
1901 | ||
1902 | * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly. | |
1903 | am29k-tdep.c (examine_prologue): Better checking of function prefixes. | |
1904 | ||
1905 | Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint) | |
1906 | ||
1907 | * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze. | |
1908 | * TODO: We did a few things, we have more to do though. | |
1909 | ||
1910 | * xm-sparc.h (CLEAR_DEFERRED_STORES): Define. | |
1911 | * inflow.c (inferior_died): Clear deferred stores. | |
1912 | ||
1913 | * Debug problems with dummy frames and calls to the inferior. | |
1914 | * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c. | |
1915 | * sparc-tdep.c (do_restore_insn): Simplify. | |
1916 | (sparc_frame_find_saved_regs): Simplify and fix what we find. | |
1917 | (sparc_push_dummy_frame): Simplify and fix what we push. | |
1918 | (sparc_pop_frame): Slightly more hair here, deciding whether | |
1919 | we are restoring a saved PC or returning to a return address in %i7. | |
1920 | * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read. | |
1921 | ||
1922 | * utils.c (xmalloc, xrealloc): Return type depends on __STDC__. | |
1923 | * symtab.h (xmalloc): ditto, for obstack_chunk_alloc. | |
1924 | * obstack.h (chunkfun): ditto. | |
1925 | * defs.h (xmalloc, xrealloc): ditto | |
1926 | ||
1927 | * utils.c (quit): Grab the terminal from the child if necessary. | |
1928 | ||
1929 | * inflow.c (term_status_command): Rename to term_info, change | |
1930 | to "info terminal". | |
1931 | ||
1932 | * sparc-pinsn.c (print_insn): Disassembly prefers real instructions. | |
1933 | (is_delayed_branch): Speed up. | |
1934 | * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables. | |
1935 | Still missing some float ops, and needs testing. | |
1936 | ||
1937 | * Support for input and output radixes other than base 10 | |
1938 | * defs.h (input_radix, output_radix): Declare. | |
1939 | * expread.y (yyparse, parse_number): Handle changes of input | |
1940 | radix, and ambiguous names-or-numbers in radixes >10. | |
1941 | * printcmd.c (print_scalar_formatted): Print formatted hex | |
1942 | numbers in varying column widths. | |
1943 | * valprint.c (val_print): Use output_format to print scalar ints. | |
1944 | (set_input_radix, set_output_radix, set_radix): Create. | |

1955 | ||
1956 | * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release. | |
1957 | bfd stuff is still screwed up, but with some manual work, it | |
1958 | compiles. | |
1959 | ||
1960 | * breakpoint.c (bpstat_do_actions): Start over if a command | |
1961 | proceeds the inferior, since the inferior will have stopped and | |
1962 | will need to have its new stop-actions taken care of. | |
1963 | ||
1964 | * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3 | |
1965 | compiler fits, simplify it. | |
1966 | ||
1967 | * gdb.texinfo (directory command): Doc new dir command. | |
1968 | source.c (directory_command): "dir" now puts things on the front | |
1969 | of the path, moves dups up front, and handles multiple names | |
1970 | on the command line, inserting each one in order. It also | |
1971 | blows away cached line and full_filename info. | |
1972 | ||
1973 | * stack.c (backtrace_command): Skip "more stack frames follow" | |
1974 | unless interactive. | |
1975 | ||
1976 | * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in | |
1977 | xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h, | |
1978 | xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h. | |
1979 | The only odd one was Gould NP1, which had defined vprintf to | |
1980 | "printf"!!! | |
1981 | ||
1982 | * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch. | |
1983 | printcmd.c (print_command_1): Pass 'inspect' flag down as a global | |
1984 | variable, inspect_it. | |
1985 | valprint.c (print_string, val_print): Use the global inspect_it | |
1986 | to indicate whether to print in Epoch style or normal style. | |
1987 | ||
1988 | Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint) | |
1989 | ||
1990 | * printcmd.c (call_command): add an alias for the "print" command | |
1991 | which runs expressions and doesn't print the result if void. | |
1992 | (print_command_1): implement it. | |
1993 | ||
1994 | * command.c: Remove #if 0'd code. Initialize all the fields | |
1995 | in add_cmd (). Rename do_nothing_command to | |
1996 | not_just_help_class_command, and make it externally visible. | |
1997 | command.h: add user_commands to struct. | |
1998 | * main.c (define_command): Don't overload c->function with a char | |
1999 | string as well as a function pointer. | |
2000 | ||
2001 | * eval.c (evaluate_subexp): Reinstall tiemann changes to | |
2002 | calling convention of value_struct_elt () that got dropped in | |
2003 | merge. | |
2004 | ||
2005 | * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c. | |
2006 | sparc-tdep.c (sparc_frame_find_saved_regs): ditto. | |
2007 | ||
2008 | * tm-sparc.h (POP_FRAME): replace some constants with defines. | |
2009 | ||
2010 | * sparc-xdep.c (store_inferior_registers): defer stores to regs | |
2011 | until a good time (e.g. when we are about to run the child), | |
2012 | saving ptrace calls. | |
2013 | * infrun.c (proceed): handle DO_DEFERRED_STORES. | |
2014 | * tm-sparc.h: define DO_DEFERRED_STORES. | |
2015 | ||
2016 | * sparc-xdep.c (store_inferior_registers): when storing float | |
2017 | registers, don't store stack regs too. When storing the SP, | |
2018 | however, DO store the stack regs too. This fixes a bug in which | |
2019 | the dummy frame is not recognized when a call_function finishes, | |
2020 | because its frame pointer (in the stack regs) was never | |
2021 | initialized. | |
2022 | (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid | |
2023 | even though we don't know how to read them from an inferior. | |
2024 | valops.c (call_function): Comment about storing SP. | |
2025 | ||
2026 | * infrun.c (save_inferior_status): Save away the original bpstat | |
2027 | chain so it can be restored later. Install the copied version for | |
2028 | use by whoever saved the status. It will be blow away by | |
2029 | restore_inferior_status, and the original chain restored. This is | |
2030 | important for people who have pointers into the original. | |
2031 | ||
2032 | * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h, | |
2033 | findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h, | |
2034 | main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint | |
2035 | ||
2036 | ||
2037 | Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com) | |
2038 | ||
2039 | * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h | |
2040 | temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW. | |
2041 | Add stuff.c and kdb-start.c to the OTHERS list for tar files. | |
2042 | ||
2043 | Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint) | |
2044 | ||
2045 | * Merge Mike Tiemann's multiple inheritance changes from Sun. | |
2046 | Store the baseclasses in a type struct starting from array element | |
2047 | 0 rather than from the unusual array element 1. | |
2048 | ||
2049 | dbxread.c: the above. | |
2050 | (virtual_context): Add | |
2051 | Read new debug information about which virtual function table | |
2052 | a virtual function is from, and store it in fn_field.fcontext. | |
2053 | ||
2054 | symtab.h: Add fcontextt. Fix baseclass indices. Typo in | |
2055 | TYPE_FN_FIELD_STATIC_P. | |
2056 | ||
2057 | symtab.c: the above. | |
2058 | valops.c: the above. Handle pointer casts of object *'s. | |
2059 | (search_struct_method): Add. | |
2060 | (value_struct_elt): First arg is now a pointer to a value, and is | |
2061 | modified on return. | |
2062 | ||
2063 | valprint.c: the above. | |
2064 | values.c (value_virtual_fn_field): Add type arg. Handle | |
2065 | offsetting to the proper object when calling virtual fns. | |
2066 | The above. | |
2067 | (baseclass_addr): Add valuep arg. | |
2068 | ||
2069 | * README: Document the current state of BFD config (missing). | |
2070 | * TODO, ChangeLog, Makefile.dist: Roll version. | |
2071 | * WHATS.NEW: Add summary of changes since 3.5. | |
2072 | ||
2073 | Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint) | |
2074 | ||
2075 | * dbxread.c (read_struct_type): Clear bit vectors whenever | |
2076 | we allocate one. | |
2077 | symtab.c (B_CLRALL): define. | |
2078 | ||
2079 | * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by | |
2080 | using == rather than =. Huh... This fixes the dreaded problem | |
2081 | wherein builtin_type_int becomes TYPE_CODE_FLT. | |
2082 | ||
2083 | * core.c (info_files): Show the inferior pid. | |
2084 | ||
2085 | * config.gdb: Avoid putting "dir" command into .gdbinit. GDB | |
2086 | already knows how to look in the source directory. | |
2087 | ||
2088 | * Remove psymtab hair from many places. Remove duplicated code | |
2089 | for searching symbol tables. Hide psymtabs from most places. | |
2090 | Make it fast to get from a psymtab to its symtab. | |
2091 | ||
2092 | blockframe.c (blockvector_for_pc): Remove psymtab hair. | |
2093 | coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2. | |
2094 | mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2. | |
2095 | dbxread.c: export psymtab_to_symtab, make it work if called N times. | |
2096 | (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize | |
2097 | new symtab completely. New psymtabs get symtab pointer | |
2098 | initialized to zero. Remove MI warning printf. | |
2099 | symtab.h: Comments. Add psymtab to symtab pointer. | |
2100 | (PSYMTAB_TO_SYMTAB): New macro. | |
2101 | symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it. | |
2102 | source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and | |
2103 | compilation fields. | |
2104 | stack.c (backtrace_command): Avoid pre-pass to read symbols, if | |
2105 | verbose is not set. | |
2106 | (print_frame_info): Avoid special-casing symbols that have not yet | |
2107 | been read in. | |
2108 | ||
2109 | * source.c (open_source_file): Quick path if we have already | |
2110 | located the source file by its full name. | |
2111 | ||
2112 | * symtab.c (lookup_symbol): Use find_pc_symtab rather than | |
2113 | find_pc_psymtab. When a name is found in the misc function | |
2114 | vector, search the symbol table for its mangled name, not the | |
2115 | name that the user typed. | |
2116 | ||
2117 | * bfd.h: Fix missing comment terminators, make #endifs match. | |
2118 | ||
2119 | * valarith.c (value_less): Handle unsigned int comparisons. | |
2120 | Add FIXME about pointer compares, which assume host and target | |
2121 | pointers are the same. | |
2122 | ||
2123 | * command.c (do_nothing_command): lint | |
2124 | dbxread.c: lint. Remove sort_syms. Document C++ visibility info, | |
2125 | fix comments on debug symbol format for visibility. Actually set | |
2126 | visibility of symbols. | |
2127 | main.c (echo_command): lint; use <readline/history.h>. | |
2128 | tm-sparc.h (FRAME_FIND_SAVED_REGS): lint | |
2129 | obstack.h (_obstack_blank): Rearrange pointer math to avoid | |
2130 | pointing past end of allocated memory; saber complains. | |
2131 | obstack.h: Declare the external functions that we use. | |
2132 | valarith.h: use <string.h> | |
2133 | solib.c (solib_add): lint. | |
2134 | ||
2135 | Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint) | |
2136 | ||
2137 | * main.c (initialize_main): Default info_verbose to off, now that | |
2138 | symbol reading is fast. | |
2139 | (quit_command): Avoid clobbering exec_bfd while quitting. | |
2140 | ||
2141 | * Initial BFD (binary file diddling library) merger: | |
2142 | coffread.c: Change AOUTHDR to struct exe_hdr. | |
2143 | dbxread.c: ditto. | |
2144 | core.c: initialize initialized data at compile time. | |
2145 | (core_file_command): Move from coredep.c, convert to bfd. | |
2146 | (xfer_core_file): Convert to bfd. | |
2147 | exec.c (exec_file_command): use bfd routines. | |
2148 | gdbcore.h: BFD. | |
2149 | mips-tdep.c: Remove exec_file_command and friends. | |
2150 | source.c: bfd. | |
2151 | ||
2152 | * coredep.c: (fetch_core_registers) Convert core_file_command to | |
2153 | fetch_core_registers. | |
2154 | mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto. | |
2155 | ||
2156 | * utils.c: (error): Bogus crap, FIXME, to print bfd errors. | |
2157 | (my_bfd_read): More bogosity, which I don't think we call. | |
2158 | (program_name): Remove this atrocity asap! | |
2159 | ||
2160 | Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint) | |
2161 | ||
2162 | * From Per Bothner: | |
2163 | values.c: allocate_repeat_value was not clearing the | |
2164 | optimized_out field. | |
2165 | (value_static_field): minor stylistic fix (wrong macro was used). | |
2166 | valops.c (value_struct_elt_for_address): didn't work for C++ | |
2167 | static fields. | |
2168 | ||
2169 | * signame.c (_initialize_signame): Initialize signal names once. | |
2170 | ||
2171 | * breakpoint.h, command.c, copying.awk, defs.h, environ.c, | |
2172 | exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c, | |
2173 | symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint. | |
2174 | ||
2175 | * remote-eb.c: Support user-settable baud rates on the serial port. | |
2176 | ||
2177 | * tm-sun3.h (PREPARE_TO_STORE): fix typo. | |
2178 | ||
2179 | Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint) | |
2180 | ||
2181 | * tconfig/sun3os4: Remove warning about native assembler, | |
2182 | since it also occurs in the xconfig file. | |
2183 | ||
2184 | * findvar.c (registers): Allocate some slop after `registers' | |
2185 | to prevent stray accesses from trashing the next variable. | |
2186 | ||
2187 | * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes | |
2188 | on the sun-3, by changing the #ifdef from `sun3' (which is not | |
2189 | defined by cc) to `sun'. Symptom was trashed builtin_type_XXX | |
2190 | vars, which happened to follow `registers' in the executable. | |
2191 | ||
2192 | * readline/history.c (history_search): Heed gcc-2's advice | |
2193 | and parenthesize && inside ||). | |
2194 | ||
2195 | * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c, | |
2196 | tm-29k.c: Insert FSF copyright headers. | |
2197 | ||
2198 | * remote-eb.c: Better comments. | |
2199 | ||
2200 | * Makefile.dist: Update to 3.91.6. | |
2201 | * TODO: note PREPARE_TO_STORE problem. | |
2202 | ||
2203 | Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint) | |
2204 | ||
2205 | * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined. | |
2206 | ||
2207 | * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE). | |
2208 | ||
2209 | * infrun.c (wait_for_inferior, at end): Don't set up | |
2210 | prev_* if the inferior no longer exists. | |
2211 | ||
2212 | * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace | |
2213 | CANNOT_EXECUTE_STACK. | |
2214 | valops.c (call_function): Use it. | |
2215 | ||
2216 | * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY. | |
2217 | ||
2218 | * inferior.h (PC_IN_CALL_DUMMY): New macro. | |
2219 | infrun.c (wait_for_inferior, 2 places): Use it. | |
2220 | ||
2221 | * values.c (value_being_returned): Only use | |
2222 | EXTRACT_STRUCT_VALUE_ADDRESS if defined. | |
2223 | ||
2224 | * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the | |
2225 | right thing for remote-eb.c. | |
2226 | ||
2227 | * sun3-xdep.c: Remove extraneous call to remote_store_registers. | |
2228 | * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto. | |
2229 | ||
2230 | * blockframe.c: Put get_frame_saved_regs inside #if !defined | |
2231 | (FRAME_FIND_SAVED_REGS). | |
2232 | ||
2233 | * findvar.c ({fetch,store}_registers): Check for | |
2234 | REMOTE_{FETCH_STORE}_REGISTER macro. | |
2235 | ||
2236 | * findvar.c (get_saved_register): Add argument lval and | |
2237 | change meaning of argument addr. | |
2238 | findvar.c: Change calls to get_saved_register to reflect | |
2239 | new calling convention. | |
2240 | valops.c (value_assign): Use get_saved_register instead of | |
2241 | find_saved_register. | |
2242 | ||
2243 | Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com) | |
2244 | ||
2245 | * coffread.c (read_one_sym): Make temp_aux an AUXENT, not | |
2246 | an (uninitialized) pointer to one. Use "&" when passing it | |
2247 | to fread. | |
2248 | ||
2249 | Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com) | |
2250 | ||
2251 | * coffread.c (getfilename): Use DGUX x_offset and x_name if | |
2252 | defined. | |
2253 | ||
2254 | * coffread.c (symbol_file_command): Put semicolon after | |
2255 | "int from_tty". | |
2256 | Put safe_to_init_tdesc_context in #if defined (TDESC). | |
2257 | Put #ifdef TDESCs in 1st column for non-ANSI cpp's. | |
2258 | coffread.c: #include <sys/stat.h>. | |
2259 | (read_coff_symtab): Typo: in_source_files -> in_source_file. | |
2260 | Add missing ')' in check for "lc%" and friends. Remove | |
2261 | extraneous '}'. | |
2262 | Declare read_one_sym() at top of file. | |
2263 | (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and | |
2264 | MC68WRMAGIC can have the same value without causing a duplicate | |
2265 | case. | |
2266 | ||
2267 | Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint) | |
2268 | ||
2269 | * Allow a Makefile to be built without building the | |
2270 | tm and xm file links that screw up builds in subdirectories. | |
2271 | This is done with `config.gdb none', then you can do things | |
2272 | like `make gdb.tar.Z'. | |
2273 | * tconfig/none: Config file for no target system | |
2274 | * xconfig/none: Config file for no host system | |
2275 | * config.gdb: If no TM or XM files are called out by the | |
2276 | host or target file, don't make links for them. | |
2277 | ||
2278 | * cplus-dem.c: Add documentation. | |
2279 | ||
2280 | * dbxread.c (read_ofile_symtab): Turn a fatal error into a | |
2281 | simple error, so the user's gdb doesn't crash due to some object | |
2282 | file problem (e.g. somebody is rebuilding the file out from under | |
2283 | gdb). | |
2284 | ||
2285 | * printcmd.c (print_address_symbolic): demangle the symbol. | |
2286 | ||
2287 | * Makefile.dist (OTHERS): Remove tdesc-lib because it has | |
2288 | Motorola copyrights in it. Make "make gdb.tar.Z" work. | |
2289 | (alldeps.mak): sort and uniq all results from this; duplicates | |
2290 | hose gdb.tar.Z link building. Remove RCS files from | |
2291 | tconfig and xconfig. Add config files for sun386. Add | |
2292 | a few odd files to OTHERS and HFILES. | |
2293 | ||
2294 | Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint) | |
2295 | ||
2296 | * Makefile.dist: Pull solib.c to tconfig/sun?os4. | |
2297 | Roll version number to 3.91.5. Make lint work in bindir. | |
2298 | ||
2299 | * README: Document cross-debugging and new file structure. | |
2300 | ||
2301 | * blockframe.c: Lint. Include "value.h" to declare read_register. | |
2302 | (find_pc_partial_function): remove duplicate line. | |
2303 | ||
2304 | * command.h: Lint. Declare error_no_arg and dont_repeat. | |
2305 | ||
2306 | * tm-news.h: Remove inadvertently duplicated stuff. | |
2307 | ||
2308 | * mipsread.c: Remove cache_pc_function stuff, now done cleanly. | |
2309 | Clean up usage of misc_function_type. Declare some CORE_ADDRs. | |
2310 | ||
2311 | * config.gdb: Allow `config.gdb host target' form. Clean | |
2312 | up previous change that printed bogus messages when you just said | |
2313 | `config.gdb'. | |
2314 | ||
2315 | * core.c: #include "command.h" for lint. | |
2316 | * dbxread.c: lint | |
2317 | * eval.c: lint | |
2318 | * main.c: Remove some casts of enums. Lint. | |
2319 | * source.c: lint | |
2320 | * symtab.c: lint | |
2321 | * symtab.h: lint | |
2322 | * expread.y: lint | |
2323 | * valarith.c: lint | |
2324 | ||
2325 | * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd. | |
2326 | ||
2327 | * sparc-tdep.c (isannulled): Take instruction as parameter, don't | |
2328 | read it from memory. This will allow us to save ptrace calls | |
2329 | eventually. Changed caller single_step too. | |
2330 | ||
2331 | * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs | |
2332 | that we aren't going to use, saving many ptrace calls, especially | |
2333 | when watchpointing or single stepping. Use some #define's for | |
2334 | constants. | |
2335 | (store_inferior_registers): Ditto. | |
2336 | (core_file_command): Use some #define's for constants. | |
2337 | ||
2338 | * tm-sparc.h: Add #define's for some register numbers, so we | |
2339 | can eliminate the use of random constants in sparc-xdep.c. | |
2340 | ||
2341 | * stack.c (frame_command, print_frame_info, up_command, | |
2342 | down_command) Remove frame_changed, since it | |
2343 | causes a bug and doesn't seem to do anything useful. In some | |
2344 | places it was used as a flag, in others as a stack level (?). | |
2345 | ||
2346 | * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the | |
2347 | default is to use the portable (vprintf) version rather than the | |
2348 | kludge version. | |
2349 | * xm-news.h (MISSING_VPRINTF): Add. | |
2350 | ||
2351 | * valprint.c (val_print): Demangle fancy vtbl printouts. Lint. | |
2352 | ||
2353 | Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint) | |
2354 | ||
2355 | * Remove stuff that forces -Bstatic linking of gdb, and warnings | |
2356 | about linking debugged programs -Bstatic in the sun?os4 config | |
2357 | files in tconfig and xconfig subdirectories. | |
2358 | ||
2359 | * main.c (main): Remove unreached exit(0) now that we exit | |
2360 | via quit_command(). | |
2361 | ||
2362 | * Create TODO file for online bug list. There are too many | |
2363 | "little" bugs to keep track of on paper. | |
2364 | ||
2365 | * Change Projects file to refer to bug-gdb@cygnus.com | |
2366 | rather than kingdon@ai. | |
2367 | ||
2368 | Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint) | |
2369 | ||
2370 | * Makefile.dist (VERSION): 3.91.4 now. | |
2371 | ||
2372 | * symtab.c (init_misc_bunches): Rename from init_misc_functions. | |
2373 | (condense_misc_bunches): Add sanity check that misc_count is | |
2374 | the same as the number of symbols in the bunch. | |
2375 | ||
2376 | * coffread.c: rename init_misc_bunches. Pass an argument | |
2377 | to condense_misc_bunches (a zero). | |
2378 | ||
2379 | * dbxread.c (partial_symbol_file_read): Call init_misc_bunches | |
2380 | every time we are called; don't rely on our caller to do it. | |
2381 | (add_file): Remove call to init_misc_bunches. | |
2382 | ||
2383 | * mipsread.c: Only warn, don't error, if unknown symbol types. | |
2384 | This keeps an old gdb from falling on its face if it sees newly | |
2385 | extended symbol info. Rename init_misc_bunches. | |
2386 | ||
2387 | Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint) | |
2388 | ||
2389 | * Merge in changes from Per Bothner for DECstations and other | |
2390 | MIPS stuff. The rest is Bothner speaking: | |
2391 | ||
2392 | The next message is a merger of Alessando Forin's mips port with | |
2393 | mine. I've tried to use my good if biased judgment to get | |
2394 | the best of both. It *does* need testing. | |
2395 | ||
2396 | Some of the changes are general, *not* mips-specific. | |
2397 | ||
2398 | param.h: | |
2399 | Didn't believe in little-endian bit order. | |
2400 | There are still inconsistencies about whether flags | |
2401 | like BITS_BIG_ENDIAN are integer (#if ...) or | |
2402 | boolean (#ifdef ...). I tried to paper over them. | |
2403 | ||
2404 | dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h: | |
2405 | Moved some misc_function code that was common to | |
2406 | {dbx,coff,mips}read.c to symtab.c. | |
2407 | In the process, I think I cleaned things up a bit. | |
2408 | At the same time, moved obsavestring and obconcat to symtab.c. | |
2409 | ||
2410 | dbxread.c: | |
2411 | Removed obsolete condense_addl_misc_bunches (use | |
2412 | condense_misc_bunches(1) instead). | |
2413 | ||
2414 | exec.c: | |
2415 | Needed to include <sys/dir>, at least on DECstations. | |
2416 | ||
2417 | valops.c, mips-tdep.c, tm-mips.h: | |
2418 | Added PUSH_ARGUMENTS macro to support funny argument-pushing | |
2419 | conventions (when STACK_ALIGN is insufficient). | |
2420 | Needed on mips, where doubles need 8-byte alignment, | |
2421 | but ints only need 4. | |
2422 | ||
2423 | mips-opcode.h: | |
2424 | Removed cruft that was not being used. | |
2425 | Merged in many fixes (most from Frank Yellin, fy@lucid.com). | |
2426 | ||
2427 | mips-pinsn.c: | |
2428 | Print $ before register-names (I think that makes things a little | |
2429 | more consistent). | |
2430 | Never print two instructions, even if one delays. | |
2431 | Removed hex-disassemble set_cmd. (This is not mips-specific, | |
2432 | so I think the argument is whether it is generally worthwhile or not. | |
2433 | I'm inclined to think not, given how easy it is to | |
2434 | convert between radixes in gdb.) | |
2435 | ||
2436 | mipsread.c: | |
2437 | This is basically Alessando's code. | |
2438 | It doesn't use obstacks; I changed it to use obstacks | |
2439 | in a few minor places where using malloc causes a | |
2440 | memory leak. (Probably, more places could/should be changed.) | |
2441 | I added record_misc_function where it was missing. | |
2442 | In symbol_file_command and add_file_command, I tried | |
2443 | to make the code consistent with more recent versions. | |
2444 | Minor sylistic changes in parse_procedure. | |
2445 | Make a .gdbinfo. psuedo-symbol point back to the real | |
2446 | procedure symbol (using the isym field). | |
2447 | ||
2448 | mips-tdep.c: | |
2449 | This is basically from my port, but with a lot of details | |
2450 | and a number of routines merged in from Alessando's version. | |
2451 | I basically used my code "raw" backtrace (use heuristics | |
2452 | from the actual code, rather than symbol table info) - though | |
2453 | the idea is Alessandro's. I feel my code is a little cleaner | |
2454 | here, particularly in being a little more flexible, such as being | |
2455 | able to handle gcc-produced code (which it now can). | |
2456 | It also doesn't do frame caching (which is not useful | |
2457 | more recent gdb versions). | |
2458 | I also used my code for push_/pop_dummy, more or less. | |
2459 | I tried to incorporate AF's code for testing sigtramp | |
2460 | while backtracing; I probably got it wrong. | |
2461 | Added mips_print_register, which tries to scrunch as much | |
2462 | information as possible on a screen... | |
2463 | Removed the skip-prologue set_cmd. As with hex-disassemble (see | |
2464 | under mips-pinsn.c), I don't see anything mips-specific here, | |
2465 | and I don't see it being all that useful anyway. | |
2466 | ||
2467 | tm-mips.h: | |
2468 | Added a $fp psuedo-reg distinct from $fp (nice for gcc). | |
2469 | Use more register names (rather than hard-cases numbers). | |
2470 | ||
2471 | Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint) | |
2472 | ||
2473 | * Hack up 3.90.11 changes: | |
2474 | ||
2475 | * Makefile.dist (depend): parameterize $(GCC). | |
2476 | Add solib.c and solib.o. | |
2477 | (readline): Fix vpath for both absolute or relative SRCDIR. | |
2478 | ||
2479 | * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs. | |
2480 | Also, let the part I didn't understand at least compile so | |
2481 | I can test the rest. FIXME. | |
2482 | ||
2483 | * dbxread.c: Fix thinko using strcmp. | |
2484 | (init_psymbol_list): declare static. | |
2485 | (partial_symbol_file_open): Comment cleanups better, avoid | |
2486 | cleaning up the string table since the caller will do that. | |
2487 | Move the stat for mod time into symbol_file_command, temporarily. | |
2488 | (There should be a mod time for each symbol file, eventually, | |
2489 | to control its rereading. FIXME.) | |
2490 | ||
2491 | * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for | |
2492 | SunOS, which gives error for shared libs otherwise. (From | |
2493 | Schaefer, probably FIXME needs work for portability.) | |
2494 | ||
2495 | * solib.c: Move #include "param.h" to work. | |
2496 | Lowercase all the Uppercase Letters In the Messages. | |
2497 | (find_solib): Clean up inferior_so_name for debug printouts. | |
2498 | Allow no argument, to mean all shared libraries. | |
2499 | ||
2500 | * symmisc.c: include param.h to get CLEAR_SOLIB. | |
2501 | ||
2502 | Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint) | |
2503 | ||
2504 | * Merge in Kingdon's changes from FSF: the diffs from 3.90.9 | |
2505 | to 3.90.11. ChangeLog entries below are from this. | |
2506 | ||

2519 | Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu) | |
2520 | ||
2521 | * sparc-opcode.h Added single-operand version of rett. | |
2522 | ||
2523 | Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu) | |
2524 | ||
2525 | * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE): | |
2526 | Put parens around gcc_p in expansion. | |
2527 | ||
2528 | Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu) | |
2529 | ||
2530 | * utils.c (lines_to_list): Return 10 if lines_per_page == 0. | |
2531 | ||
2532 | Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu) | |
2533 | ||
2534 | * Changes for Sun shared libraries: | |
2535 | blockframe.c (find_pc_partial_function): If a non-text symbol | |
2536 | is found, set *address = pc - FUNCTION_START_OFFSET. | |
2537 | breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]: | |
2538 | Disable breakpoints instead of giving an error. | |
2539 | source.c (select_source_symtab): Initialize cs_pst. | |
2540 | symmisc.c: Call CLEAR_SOLIB if defined. | |
2541 | symtab.h: Make text{low,high} CORE_ADDR not int. | |
2542 | (psymtab): New field addr. | |
2543 | solib.c: New file. | |
2544 | dbxread.c: Move DECLARE_FILE_HEADERS outside functions. | |
2545 | (record_misc_function): Give correct type for N_DATA symbols. | |
2546 | (condense_misc_bunches): do "misc_function_count = j" regardless | |
2547 | of inclink. | |
2548 | Take code which is shared between symbol_file_command and | |
2549 | add_file_command and put it into partial_symbol_file_{open,read}. | |
2550 | Split add_file_command into add_file_command and add_file. | |
2551 | Make psymtab_to_symtab read in the string table if the file | |
2552 | is not symfile. | |
2553 | Two new parameters to read_dbx_symtab and start_psymtab. | |
2554 | tm-sunos.h: New file. | |
2555 | ||
2556 | Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu) | |
2557 | ||
2558 | * infcmd.c: Change cont_command to continue_command and "cont" | |
2559 | to "continue". | |
2560 | ||
2561 | Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu) | |
2562 | ||
2563 | * breakpoint.c (enable_breakpoint): Get value of watchpoint. | |
2564 | ||
2565 | * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__. | |
2566 | ||
2567 | * values.c (USE_STRUCT_CONVENTION): Check for structures of | |
2568 | size 1,2,4,8 rather than size < 8. | |
2569 | ||
2570 | * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times | |
2571 | as necessary, not just once. | |
2572 | ||
2573 | * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports. | |
2574 | ||
2575 | Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu) | |
2576 | ||
2577 | * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386 | |
2578 | ||
2579 | * tm-news.h: Add CALL_DUMMY_*. | |
2580 | ||
2581 | * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS. | |
2582 | ||
2583 | * config.gdb: In list_host, list_target, use ${i}, not $i. | |
2584 | ||
2585 | Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu) | |
2586 | ||
2587 | * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc. | |
2588 | ||
2589 | * sparc-opcode.h: Change all store floating-point state register | |
2590 | instructions to have the right match & lose fields. | |
2591 | ||
2592 | Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu) | |
2593 | ||
2594 | * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass | |
2595 | VPATH to readline. | |
2596 | config.gdb: If srcdir != ., create readline directory and | |
2597 | copy a makefile into it. | |
2598 | ||
2599 | * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for | |
2600 | consistency with POSIX. | |
2601 | ||
2602 | * breakpoint.c (bpstat_stop_status): Disable watchpoint | |
2603 | when we exit its exp_valid_block. | |
2604 | ||
2605 | Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint) | |
2606 | ||
2607 | * Makefile.dist: Bump version to 3.91.3. | |
2608 | ||
2609 | * Clean up handling of breakpoint commands (somewhat). | |
2610 | Prompted by Tiemann bug report "cont 10" doesn't work any more. | |
2611 | ||
2612 | inferior.h: Add breakpoint_proceeded to inferior status struct | |
2613 | and globals; save it and restore it. | |
2614 | (clear_breakpoint_commands): Cleanup, remove old #define. | |
2615 | ||
2616 | infrun.c (clear_proceed_status): Set breakpoint_proceeded. | |
2617 | (save_inferior_status, restore_inferior_status): handle it also. | |
2618 | (proceed): Remove earlier code that set breakpoint_proceeded. | |
2619 | It is now set only in clear_proceed_status. | |
2620 | (clear_proceed_status): Cleanup, use bpstat_clear rather | |
2621 | than clear_breakpoint_commands. No callers need the stop_bpstat | |
2622 | between clear_proceed_status and proceed. | |
2623 | ||
2624 | infcmd.c: Add breakpoint_proceeded definition and comment. | |
2625 | (cont_command, jump_command, signal_command): Move call to | |
2626 | clear_proceed_status right next to call to proceed. | |
2627 | ||
2628 | breakpoint.c (bpstat_do_actions): Avoid clobbering our | |
2629 | caller's argument while running down the chain of breakpoints. | |
2630 | Use new variable "breakpoint_proceeded" to determine when | |
2631 | a command that it executes moves the inferior past the | |
2632 | breakpoint. | |
2633 | (bpstat_clear): Handle NULL argument. | |
2634 | (bpstat_clear_actions): Avoid useless call to | |
2635 | breakpoint_auto_delete. | |
2636 | (delete_breakpoint): Clean up bpstat's that are pointing to | |
2637 | the deleted breakpoint from the stop_bpstat chain. | |
2638 | (breakpoint_auto_delete): Simplify. | |
2639 | ||
2640 | * Clean up handling of EOF, error on stdin, etc. This was | |
2641 | prompted by a network problem that caused gdb to go into an | |
2642 | infinite loop filling up its malloc'd memory. | |
2643 | ||
2644 | main.c (return_to_top_level): Cleanup: call bpstat_clear_actions, | |
2645 | not clear_breakpoints_commands, which is now gone. | |
2646 | (main): If command_loop returns (e.g. from EOF on stdin), do | |
2647 | a quit_command (looping back to command_loop if quit_command | |
2648 | doesn't really quit). | |
2649 | (command_loop): check result from command_line_input and | |
2650 | exit if it returns NULL, rather than passing the NULL to | |
2651 | execute_command. | |
2652 | (gdb_readline): Free malloc'd result space before returning | |
2653 | NULL for EOF. | |
2654 | ||
2655 | * utils.c (query): Handle C-d to mean "yes", just as if the | |
2656 | input was not a terminal. Also avoid infinite loop if EOF | |
2657 | occurs in mid-input-line before newline. This allows | |
2658 | query to be used at EOF on stdin with reasonable results. | |
2659 | ||
2660 | * infrun.c (proceed): Set breakpoint_proceeded. | |
2661 | ||
2662 | * values.c (value_as_long): Avoid infinite recursion for enums. | |
2663 | (_initialize_values): Fix typo in help msg (kingdon). | |
2664 | ||
2665 | * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies, | |
2666 | RL_LIB for linking. This allows -lreadline for linking | |
2667 | and nothing for dependencies, once readline is a real library. | |
2668 | ||
2669 | * config.gdb: Jim Kingdon: give useful error message if the | |
2670 | host or target type is not recognized. | |
2671 | ||
2672 | * defs.h (alloca): SPARC <alloca.h> does not declare alloca, | |
2673 | it just defines it. Dumb, but deal with it. | |
2674 | ||
2675 | * Jim Kingdon suggests: | |
2676 | in xconfig/sun3os4, CFLAGS should be XM_CFLAGS. | |
2677 | ||
2678 | Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint) | |
2679 | ||
2680 | * Makefile.dist (VERSION): Bump version # to 3.91.2. | |
2681 | ||
2682 | * Clean up Bothner's changes. | |
2683 | ||
2684 | * blockframe.c (clear_pc_function_cache): New function. | |
2685 | * blockframe.c: remake cache_pc_function_* static. | |
2686 | * dbxread.c (symbol_file_command): remove references to | |
2687 | cache_pc_function_* variables. | |
2688 | * dbxread.c (read_struct_type): Use VOFFSET_STATIC. | |
2689 | * printcmd.c: Avoid kludging a global variable (addressprint) | |
2690 | to avoid printing the address of a string twice. Instead, | |
2691 | pass the format letter 's' down low enough that it can be seen | |
2692 | to avoid this problem. | |
2693 | (print_formatted): Pass format arg to value_print. | |
2694 | (restore_addressprint): Remove function. | |
2695 | (do_examine): Avoid hacking addressprint, cleanups and such. | |
2696 | (print_frame_args): Add a comment to a Bothner change. | |
2697 | * symtab.h: define VOFFSET_STATIC and use it instead of "-1". | |
2698 | * symmisc.c (free_all_symtabs): Call clear_pc_function_cache | |
2699 | to wipe out the values cached in blockframe.c. | |
2700 | * symtab.c (find_method): Add comment saying how big you must | |
2701 | allocate to be "big enough". Per being terse again. | |
2702 | * valprint.c (val_print): Handle format letter "s" to print | |
2703 | strings without addresses. Add comment to vtbl printing code | |
2704 | which casts with wild abandon. Rearrange reference-printing | |
2705 | code so it prints: | |
2706 | @0xaddr: value (print w/addressprint) | |
2707 | value (print w/~addressprint) | |
2708 | @0xaddr (parameter lists w/addressprint) | |
2709 | or nothing (parameter lists w/o addressprint) | |
2710 | ||
2711 | Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint) | |
2712 | ||
2713 | * Merge more changes from Per Bothner: | |
2714 | ||
2715 | Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise | |
2716 | annoying) that I tried to improve it. Here are my suggestions. | |
2717 | ||
2718 | These patches all attempt to handle TYPE_CODE_REF (as in C++) better. | |
2719 | ||
2720 | findvar.c: | |
2721 | Do automatic de-reference when taking the address of a reference. | |
2722 | printcmd.c: | |
2723 | Don't deref_ref when printing parameter lists. | |
2724 | valops.c: | |
2725 | More attempts at treating refernences properly. | |
2726 | valprint.c: | |
2727 | In val_print, if deref_ref==0, don't print dangling " = ". | |
2728 | value.h: | |
2729 | Add COERCE_REF macro, which de-references an REF. | |
2730 | ||
2731 | * Merge changes from Per Bothner: | |
2732 | ||
2733 | * Fixed (Sony news)-specific configuration problems. | |
2734 | * Fixed other problems with using vanilla pcc and libc (enum problems; | |
2735 | assumption that vsprintf exists). | |
2736 | * Some major speed-ups (finc_pc_partial_function now caches a match; | |
2737 | parsing avoids duplicate symbol_lookup calls). | |
2738 | * Changed handling of baseclasses (no longer use baseclasses field | |
2739 | of struct type, use the first n_baseclasses fields instead). | |
2740 | * Various minor changes/fixes, most C++-related. | |
2741 | ||
2742 | blockframe.c: | |
2743 | Cache the most previous match from find_pc_partial_function. | |
2744 | (Save both low and high ends of matching function's pc range.) | |
2745 | This speeds up the loop of infrun.c:wait_for_inferior quite | |
2746 | a bit, and makes step/next commands much zippier. | |
2747 | command.c: | |
2748 | Added an enum->int cast (otherwise, some compilers barf). | |
2749 | dbxread.c: | |
2750 | No longer set baseclass offset to 0, since multiple | |
2751 | inheritance now mostly works. | |
2752 | Added a number of casts, to shut up compiler warnings | |
2753 | (after stabs where made enums, not ints). | |
2754 | When discarding a symbol table (in symbol_file_command), | |
2755 | must clear the cache introduced in blockframe.c. | |
2756 | Don't convert $vtbl_ptr_type to vtbl any more. | |
2757 | Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h). | |
2758 | Mask off sign bit emitted by g++ for virtual table offset. | |
2759 | Set voffset to -1 (not 1) for static member functions. | |
2760 | expread.y: | |
2761 | Changed parsing/lexing of names to avoid doing symbol lookup twice | |
2762 | (once when lexing to determine symbol class, once for real). | |
2763 | Now only call symbol_lookup once. Fields of 'this' win especially big. | |
2764 | printcmd.c: | |
2765 | Subpress printing addr twice in the case of 'x/s addr'. | |
2766 | symtab.c: | |
2767 | lookup_basetype_type is no longer used. | |
2768 | Add find_methods as recursive helper function to decode_line_1. | |
2769 | This allows multiple inheritance to work. | |
2770 | Also, once one or more matches has been found, do not look in | |
2771 | base-classes. (Baseclass methods would be overridden, anyway.) | |
2772 | symtab.h: | |
2773 | Removed baseclasses array in struct type. | |
2774 | Instead of using baseclasses[i], use fields[i-1]. | |
2775 | Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual. | |
2776 | Changed sign convention of voffset (previous was inconsistent). | |
2777 | tm-news.h: | |
2778 | Some macros (CALL_DUMMY and relatives) were missing. Put them back. | |
2779 | utils.c: | |
2780 | Used to assume existence of vsprintf. Re-written to not need it | |
2781 | if HAVE_VPRINTF is undefined. | |
2782 | valops.c: | |
2783 | typecmp was too pessimistic. Made it less so. | |
2784 | valprint.c: | |
2785 | Don't print space after address. | |
2786 | If vtable points to a misc symbol (with 0 offset), print it, | |
2787 | since that indicates the actual class of the object. | |
2788 | Changed ype_print_derivation_info to use new inheritance | |
2789 | scheme (without baseclasses vector). | |
2790 | values.c: | |
2791 | In value_primitive_field, fixed some bugs left over from previous set of fixes. | |
2792 | Also, changes needed because TYPE_BASECLASSES were removed. | |
2793 | xm-news.h: | |
2794 | REGISTER_U_ADDR didn't work for PC. Rewrote to use an array. | |
2795 | ||
2796 | Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint) | |
2797 | ||
2798 | * source.c: | |
2799 | If there is no path set, and the symbols don't indicate what directory | |
2800 | a file was compiled in, look in the current directory. But either | |
2801 | a path or a known compilation directory will prevent this. | |
2802 | ||
2803 | * dbxread.c: | |
2804 | Three independent bug fixes: | |
2805 | * Remove the #if 0 block that breaks some stuff. | |
2806 | * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C; | |
2807 | adapt gdb to either SunOS 4.0.* or 4.1. | |
2808 | * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think. | |
2809 | ||
2810 | * symtab.c: | |
2811 | Instantiate the class T when looking for methods in it. (Tiemann@sun) | |
2812 | ||
2813 | * valprint.c: | |
2814 | (type_print) Demangle the name being printed. | |
2815 | (type_print_base) Handle botched demangling without coredump (tiemann). | |
2816 | ||
2817 | * values.c: | |
2818 | (check_stub_method): Document routine. | |
2819 | (tiemann) fix bug for no-arg functions | |
2820 | Avoid clobbering beyond end of malloc'd storage. | |
2821 | Terminate the argument list properly. | |
2822 | ||
2823 | Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu) | |
2824 | ||
2825 | * Changes merged by John Gilmore: | |
2826 | ||
2827 | breakpoint.c: | |
2828 | In breakpoint_1, use new print_address_symbolic instead | |
2829 | of find_pc_partial_function. (This forces use of assembler-level | |
2830 | addresses, and avoids misleading non-mangled source-level names.) | |
2831 | cplus-dem.c: | |
2832 | Generalize ansi argument such that -1 means skip arglist totally. | |
2833 | Removed global variable print_ansi_qualifiers (which made | |
2834 | code non-reentrant), in favor of extra explicit arguments | |
2835 | to internal routines. | |
2836 | printcmd.c: | |
2837 | Add new helper function print_address_symbolic. | |
2838 | Use find_pc_misc_function instead of find_pc_partial_function | |
2839 | (since we want assembler-level symbols here). | |
2840 | stack.c: | |
2841 | Print unknown function as just "f (...)", not "f (...) (...)". | |
2842 | Use new fputs_demangled explicitly. | |
2843 | symtab.c: | |
2844 | Fixed a typing violation (problem: value.h cannot be imported | |
2845 | without renaming many variable in this file). | |
2846 | lookup_symbol: If no matching misc_func, look for a C++-mangled name. | |
2847 | decode_line_1: Moved forward some never-reached code. | |
2848 | Made decode_line_2 skip function prologues correctly. | |
2849 | utils.c: | |
2850 | fputs_filtered should not demangle by default. | |
2851 | Add new fputs_demangled to demangle on demand.. | |
2852 | valops.c: | |
2853 | Change value_struct_elt to use value_primitive_field (using recursive | |
2854 | utility function search_struct_field). This allows foo.bar to work | |
2855 | for multiple inheritance (so far only for data fields). | |
2856 | Change check_field in the same way (recursive helper function | |
2857 | to support multiple inheritance). | |
2858 | (Note: there are more of these problems that I haven't fixed. | |
2859 | Any code that says TYPE_BASECLASS (t, 1) is probably wrong.) | |
2860 | value_of_this: 'this' symbol name is now just "this", note "$this". | |
2861 | valprint.c: | |
2862 | Don't print static members. | |
2863 | Avoid printing "members of <type>" if there are none. | |
2864 | Simplified type_print_derivation_info by merging duplicate code. | |
2865 | Remove useless blank lines in type_print_base (ptype command). | |
2866 | value.h: | |
2867 | Added declaration of new routine value_primitive_field. | |
2868 | values.c: | |
2869 | Added value_primitive_field which is generalized version of | |
2870 | value_field that can handle multiple inheritance (non-zero offsets etc). | |
2871 | Re-implemented value_field to call value_primitive_field. | |
2872 | ||
2873 | Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint) | |
2874 | ||
2875 | * infcmd.c -- insert else to avoid 'delete env' coredump when you | |
2876 | delete the whole environment. Karl Berry reported the bug. | |
2877 | * source.c - fix openp to avoid //'s in filenames, which | |
2878 | trigger an Emacs bug causing it to not be able to find files | |
2879 | when running gdb in a window. | |
2880 | * dbxread.c - zap the #if 0 that botches the add-file code. | |
2881 | It seems to work a lot better without all the code commented out. | |
2882 | ||
2883 | Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com) | |
2884 | ||
2885 | * Merge Tiemann's and Ted Goldstein's changes, detailed below, | |
2886 | into gdb-3.90.9. | |
2887 | ||
2888 | Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem) | |
2889 | ||
2890 | * Makefile - added a ${CFLAGS} to a couple of entries, | |
2891 | added remote-sa.sparc.c | |
2892 | * added remote.sa-sparc.c, a modification of remote.c | |
2893 | which conducts a dialog directly with the SparcStation prom. | |
2894 | * breakpoint.c, infrun.c, sparcdep.c added | |
2895 | remote_insert_breakpoint(), and remote_remove_breakpoint() | |
2896 | to breakpoint.c instead of directly writing breakpoint instructions. | |
2897 | * sparcdep.c on remote_debugging,there is no need | |
2898 | to remove signle step breakpoint instructions. | |
2899 | * main.c added "-epoch" flag and "int epoch_interface" to main.c | |
2900 | global variable | |
2901 | * printcmd.c - epoch interface sends lisp expressions to open up | |
2902 | epoch windows on inspection. | |
2903 | * valprint.c - added arrayprint, and addressprint and made adding | |
2904 | format controls easier | |
2905 | * wait.h added a couple of undef's because we were getting | |
2906 | complaints about WSTOPSIG and WTERMSIG begin redefined. | |
2907 | ||

2915 | ||
2916 | * values.c (baseclass_addr): Run loop from INDEX+1 to | |
2917 | N_BASECLASSES; otherwise, we can still get into a loop. | |
2918 | @@ This should be restructured to use a cleaner search strategy. | |
2919 | ||
2920 | Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham) | |
2921 | ||
2922 | * dbxread.c (define_symbol,read_type): Grok GNU C++'s new | |
2923 | abbreviation "Tt" for tags which have the same name as their | |

2932 | ||
2933 | * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we | |
2934 | should print ANSI qualifiers (such as `const' and `volatile'). | |
2935 | All callers changed to call with ANSI == 1, except from | |
2936 | `check_method_stub', which uses old-style syntax. | |
2937 | ||
2938 | * symseg.h (struct fn_field): Remove unneccessary `args' field. | |
2939 | * symtab.h (TYPE_FN_FIELD_ARGS): Redefined. | |

2944 | ||
2945 | * dbxread.c (read_type): Handle new GNU C++ method type stubs. | |
2946 | * valprint (type_print_base): Ditto. | |

2949 | ||
2950 | Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla) | |
2951 | ||
2952 | * breakpoint.c (catch_command): New function. Provides a | |
2953 | mechanism to set breakpoints based on catch clauses. | |
2954 | (disable_catch): Similar, but disables breakpoints on catch | |
2955 | clauses. | |
2956 | (delete_catch): Similar, but deleted breakpoints on catch clauses. | |

2965 | exceptions which can be caught in the current frame. | |
2966 | * stack.c (print_frame_label_vars): New function. Similar to | |
2967 | `print_frame_local_vars'. | |
2968 | * stack.c (print_block_frame_labels): Prints out labels that are | |
2969 | defined in this frame. These labels are exceptions that can be | |
2970 | caught. | |
2971 | ||
2972 | * dbxread.c: Updated to handle N_CATCH symtab types. | |
2973 | ||

2975 | ||
2976 | * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the | |
2977 | form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME | |
2978 | when printing the type. | |
2979 | ||
2980 | Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake) | |

2993 | Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu) | |
2994 | ||
2995 | * breakpoint.c (watch_command, bpstat_stop_status): Deal with | |
2996 | exp_valid_block field correctly. | |
2997 | ||
2998 | * infrun.c (wait_for_inferior): When checking "don't even think | |
2999 | about breakpoints" if stop_signal == SIGTRAP && trap_expected, | |
3000 | also check step_resume_breakpoint. | |
3001 | Insert breakpoints and continue (not step) if | |
3002 | step_resume_break_address != NULL, even if another_trap. | |
3003 | If trap_expected and we enter sigtramp, then set up a | |
3004 | step_resume_break. | |
3005 | If trap_expected is set when we hit the step_resume_break, | |
3006 | set another_trap. | |
3007 | When calling resume and trap_expected says tell resume to step | |

3018 | * infrun.c (wait_for_inferior, after check for trap_expected > 1): | |
3019 | Restore old code which distinguishes between trap_expected and | |
3020 | running_in_shell, just make the latter take any non-TRAP signal, | |
3021 | not just SEGV. | |
3022 | ||
3023 | * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag. | |
3024 | ||
