2
 
3
        Further stabilization for the Intel 960.
4
 
5
        * Makefile.dist: Parameterize the location of the "include"
6
        and "bfd" directories, as well as "getopt".  Add symfile.c.
7
        Link in both dbxread and coffread.  Fix up "make depend" to
8
        rewack the locations of include, bfd, and getopt in its output.
9
 
10
        * README:  Document moving include files, improve some of
11
        the other doc.
12
 
13
        * coffread.c:  Move common code out to symfile.c.  Change
14
        symbol_file_command style interface to use new *_symfile_init
15
        and *_symfile_read interface under BFD.  Use BFD internal
16
        info to locate line table, symbols, etc.
17
 
18
        * core.c (core_fetch_registers):  Rename to get_core_registers
19
        to avoid confusion with fetch_core_registers.
20
        (register_addr):  Move to coredep.c, which is already machine
21
        dependent.  This leaves core.c pretty clean of dependencies.
22
 
23
        * coredep.c (register_addr):  Accept this routine from core.c.
24
 
25
        * dbxread.c: Move common code (with coffread.c, etc) into new
26
        symfile.c.  Each psymtab now contains a pointer to the
27
        format-dependent function that knows how to read it in.  Make
28
        some things static.
29
        (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
30
        (process_one_symbol): Add code to complain about a "compiler bug
31
        we muzzle here", if we actually see it.
32
 
33
        * eval.c (evaluate_subexp):  Insert missing "break" statements
34
        in code that determines whether a variable is an lvalue in
35
        memory, register, or whatever.  I detected this via a compiler
36
        bug in which it *almost* mashed out the whole switch statement.
37
 
38
        * gdb-int.texinfo:  Add minor sections on configuring gdb for
39
        release, and about the README file.
40
 
41
        * infcmd.c (registers_info):  Fix formatting somewhat.  Still
42
        not as pretty as before, but it handles byte swapping.
43
 
44
        * remote-nindy.c: If data cache routines are interrupted while
45
        waiting for the remote end, be sure that any uninitialized cache
46
        blocks are on the free list, not on the valid list!
47
 
48
        * symfile.h: Flesh out this header file with all the various
49
        routines and variables that have been merged in from dbxread.c
50
        coffread.c, and symtab.c to symfile.c.
51
 
52
        * symfile.c: New file, containing code common to dbxread.c,
53
        coffread.c, and some code from symtab.c.  All generic code for
54
        reading symbol files should be in here now.
55
        (unrecord_misc_function):  Remove unused function.
56
 
57
        * symtab.h:  Remove file-reading things to symfile.h.
58
 
59
        * symtab.c:  Remove file-reading things to symfile.c.
60
 
61
        * tm-i960.h:  Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
62
        to decode i960 fault types.
63
 
64
        * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
65
        target.c: Change type of the "resume" function from int to void,
66
        since its result was never used.
67
 
68
Sat Dec 22 02:51:40 1990  John Gilmore  (gnu at cygint)
69
 
70
        * main.c:  Replace "stupid" with "caution"; you now "set caution
71
        on or off".
72
 
73
        * printcmd.c (print_scalar_formatted):  Fix typo in 'g' format
74
 
75
        * infcmd.c (do_registers_info):  Call val_print to deal with the
76
        byte order of the registers being printed.  FIXME, this makes
77
        the formatting of the output uglier.
78
 
79
        * infcmd.c (wait_for_inferior):  If PRINT_RANDOM_SIGNAL is
80
        defined, call it for signals the debugger doesn't itself use.
81
        The i960 uses this for more detailed fault information.
82
 
83
        * remote.c (remote_open):  If arg is null, print help rather than
84
        dumping core.
85
 
86
        * sparc-xdep.c (register_valid):  Avoid declaring size, since
87
        various modules will think of various sizes depending on the
88
        architecture of their tm-file.  FIXME, we need protection against
89
        actually entering one of those modules, which would clobber
90
        storage if not for the target architecture compiled into gdb.
91
 
92
        * stack.c (up_command, down_command):  Always print the frame
93
        you arrive at.
94
        (up_silently_command, down_silently_command):  New commands
95
        for use in scripts.
96
 
97
        * i960-pinsn.c (reg), i960-tdep.c:  Lint.
98
 
99
        * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
100
        more parameters than it used to.
101
 
102
        * findvar.c (registers):  Increase slop to 256 bytes, which should
103
        protect us against even most RISC machines with large register
104
        sets.
105
        (locate_var_value):  Move declaration inside related ifdef.
106
 
107
        * remote-nindy.c ():  Use TIOCSETN rather than TIOCSETP
108
        throughout, to avoid throwing away buffered input from the board.
109
        (nindy_wait):  Supply_register takes addr_of_value, not value.
110
        (i960_print_fault):  Renamed from i80960_fault.
111
        (nindy_fetch_registers):  Avoid have_regs stuff, just get them.
112
        (nindy_store_registers):  Avoid regs_changed stuff, just stuff
113
        them.
114
        (nindy_create_inferior):  Don't bother to write PC_REGNUM since
115
        we can set the PC in the call to proceed().  Unpush nindy_ops
116
        before pushing it on top, to avoid message to user.  Eliminate
117
        commentary from Unix machines that just misleads here.
118
        (reset_command):  Fix error message to suggest target command.
119
 
120
Wed Dec 19 11:03:56 1990  John Gilmore  (gnu at cygint)
121
 
122
        Release 3.92.5 as frozen.
123
 
124
        Stabilize the merged release...with help from lint, Saber C,
125
        gcc -W, etc.
126
 
127
        Everywhere:  Add include files needed to declare return types
128
        of functions called.
129
 
130
        * gdb.texinfo:  Roland Pesch is documenting gdb, glory be!
131
 
132
        * breakpoint.h:  Add undeclared breakpoint functions, and some
133
        functions for display handling since I couldn't think of a better
134
        .h to put them in.
135
 
136
        * breakpoint.c (insert_breakpoints):  Make code for disabling
137
        shared library bkpts more likely to work.  It's used when we
138
        rerun a program and stop before the shared library has been
139
        mapped in.
140
        (breakpoint_cond_eval, bpstat_stop_status):  Pass arg as int,
141
        cast from pointer, so it squeezes through catch_errors.
142
        (bpstat_stop_status):  Fix logic broken some time ago.  We now
143
        always create a bpstat if the stop address matches a breakpoint,
144
        even if we don't stop there -- just like the old code used to do
145
        before I got my fingers into it (sigh).
146
        (breakpoint_1):  Print "ignore count" after "stop only if"
147
        condition, since that's how it actually works.
148
        (mention):  Handle watchpoints as well as breakpoints.
149
        (watch_command):  use set_raw_breakpoint and mention to do most
150
        of the work (and initialize all the fields!).  Only pass one
151
        arg to parse_c_expression, since that's all it takes.
152
 
153
        * command.c (not_just_help_class_command):  Rename arg to args
154
        since we ignore "unused argument" warnings on vars named "args".
155
        inflow.c (child_terminal_info):  ditto.
156
        infptrace.c (kill_inferior):  ditto
157
        main.c (catch_errors, version_info, quit_command, pwd_command,
158
        source_command, dump_me_command, editing_info,
159
        set_history_size_command, set_history, show_history,
160
        set_verbose): ditto
161
        stack.c (locals_info):  ditto
162
        target.c (target_files_info):  ditto
163
        valprint.c (set_input_radix, set_output_radix):  ditto
164
 
165
        * core.c:  Remove old variables for handling core and exec file
166
        sections (data_start, data_end, stack_start, stack_end,
167
        reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
168
        text_end, exec_data_start, exec_data_end, text_offset,
169
        exec_data_offset, data_offset, stack_offset).  They're
170
        superseded the more general build_section_table and
171
        xfer_memory.
172
        (get_exec_file):  Mention the `file' command.
173
        (read_memory_check):  Rename to memory_error, and only call it
174
        in the case of an actual error.
175
        (read_memory, write_memory):  call memory_error.
176
        (core_fetch_registers):  Register section name is ".reg".
177
 
178
        coredep.c:  Remove a bunch of crud now that all this file does
179
        is pull the registers out of a core file.
180
        (fetch_core_registers):  Rewrite to actually work, I hope.
181
 
182
        dbxread.c:  Use a.out.gnu.h, not system a.out, now.
183
        Replace index() with strchr().  Remove all the pre-BFD macro
184
        definitions for accessing the symbol file.
185
        (struct dbx_symfile_info):  Encapsulate the information that
186
        dbx_symfile_init needs to pass to dbx_symfile_read in this
187
        struct.
188
 
189
        (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
190
        dbx_symfile_discard): Rearrange symbol file reading to divide
191
        the format-specific part from the format-independent part,
192
        leaving the format-independent part such as file name expansion
193
        and opening in symtab.c.  This replaces
194
        partial_symbol_file_open and partial_symbol_file_read.
195
        Symbol_file_read, add_file, add_file_target_command,
196
        add_file_addr_command move to symtab.c.  Pass an explicit
197
        "mainline" flag for when reading the main symbol table, rather
198
        than relying on the offset address to be zero or nonzero.
199
 
200
        (dbx_symfile_read): Don't allow void *'s to be printed as
201
        typedefs.
202
        (SWAP_SYMBOL):  Use bfd routines to byte-swap the symbols.
203
        (ADD_PSYMBOL_TO_LIST):  Make the "function call rather than
204
        macro" debug version really work.
205
        (read_dbx_symtab):  Remove unref'd parameter inclink.
206
        Avoid swapping N_SLINE symbols, for speed.
207
        Merge N_TEXT!N_EXT case with the other external symbol
208
        definitions' case. Add comments.
209
        (start_psymtab):  Allocate the symfile name in the psymtab on
210
        the psymbol_obstack, rather than using the caller's storage.
211
        (end_psymtab): Only allocate a dependencies list if there are
212
        more than zero.
213
        (psymtab_to_symtab_2):  Use BFD when reopening file to read
214
        its symbols for real.
215
        (read_struct_type):  Add FIXME comments where it needs work
216
        for C++ bogosity.
217
        (read_huge_number):  Add FIXME about overflows.
218
        (read_range_type):  Add FIXME about comparing a long to 1<<32.
219
 
220
        * coffread.c:  Minor changes to move things closer to the new
221
        regime with symtab.c and dbxread.c   Major work is still needed
222
        here.
223
 
224
        * exec.c (exec_file_command):  Remove old variables (see core.c
225
        above).
226
        (xfer_memory): If memory transfer is right at the end of a
227
        section, don't lose.
228
 
229
        * findvar.c (get_saved_register):  If value is in a real
230
        register, LVAL is lval_register, not lval_memory.
231
 
232
        frame.h:  Declare print_sel_frame and record_selected_frame.
233
 
234
        gdb-int.texinfo:  New file, for GDB internals documentation.
235
        Very simple, unformatted doc of cleanups is there for now.
236
 
237
        gdbcore.h:  Remove obsolete variables that described a.out
238
        section addresses and offsets.  (See core.c above.)
239
        Declare fetch_core_registers and registers_fetched.
240
 
241
        getopt.c:  Declare char *alloca(); even on SPARC.
242
 
243
        infcmd.c (run_command):  Call target_kill rather than
244
        kill_inferior.
245
        (step_command, next_command, stepi_command, nexti_command):
246
        Declare from_tty parameter even though we don't use it.
247
        (run_stack_dummy):  argument BUFFER is a char array, not
248
        a pointer to REGISTER_TYPE.
249
        (finish_command):  using_struct_return needed a value *,
250
        not a struct symbol *.
251
 
252
        * infptrace.c (child_xfer_memory):  To avoid dependency on
253
        where sections are in memory, try PT_WRITE_D and if that fails,
254
        try PT_WRITE_I.  Most Unixes don't care which you use.
255
 
256
        * infrun.c (step_resume_break_shadow):  Change to array to
257
        match other breakpoint shadow storage.
258
        (clear_proceed_status):  Pass address of bpstat to
259
        bpstat_clear, not the bpstat itself.
260
        (child_create_inferior):  FIXME comment about if the child
261
        exits.
262
        (start_inferior):  Remove old function.
263
        (child_open):  Use target_kill rather than kill_inferior.
264
        (wait_for_inferior):  Ditto.
265
        (insert_step_breakpoint, remote_step_breakpoint):  Use
266
        new step_resume_break_shadow.
267
 
268
        * inftarg.c (child_wait):  If all child processes die,
269
        pretend that the one being waited for exited with signal 42.
270
 
271
        * main.c (command_line_input):  When scanning for comments,
272
        don't coredump on unclosed quotes.
273
        (quit_command):  Use target_kill rther than kill_inferior.
274
        (_initialize_main):  Rename class_user from "user" to
275
        "user-defined".
276
 
277
        * printcmd.c (print_command_1):  Initialize "fmt" if no format
278
        is specified by the user.
279
        (print_frame_args):  Only add to args_printed if we are
280
        actually fetching args from the stack (avoiding undefined
281
        arg_size).
282
        (_initialize_printcmd):  Remove bogus \{ from string.
283
 
284
        * remote-eb.c (eb_open):  Avoid coredump on no argument.
285
 
286
        * remote-nindy.c:  Bring out of Intel environment into new
287
        target environment.  Remove all conditional compilation on
288
        I80960.  Massive hacking throughout.
289
        (nindy_xfer_inferior_memory):  New routine stolen from
290
        infptrace.c.
291
        (nindy_create_inferior):  New routine pieced together, probably
292
        not quite working yet.
293
        (nindy_ops):  New target_ops struct for nindy.
294
 
295
        * remote-vx.c:  Use write_memory rather than target_write_memory
296
        to get error checking.
297
        (vx_add_file_command, vx_open): Use symbol_file_add rather than
298
        add_file.
299
        (vx_create_inferior):  Use target_terminal_ours...
300
 
301
        * signame.c (_initialize_signame):  Always initialize, since
302
        we need the table for things other than psignal.
303
 
304
        * solib.c (solib_add):  Use symbol_file_add, not add_file.
305
        (solib_address):  Return boolean result rather than struct
306
        pointer which nobody else knows the type of.
307
 
308
        * sparc-tdep.c, valops.c:  Use write_memory rather than
309
        target_write_memory, to get error checking.
310
 
311
        * stack.c (locals_info, catch_info, args_info,
312
        get_selected_block, frame_command, up_command): Use
313
        target_has_stack, rather than have_inferior_p or
314
        have_core_file_p.
315
 
316
        * sun3-xdep.c (fetch_core_registers):  Rewrite for new BFD regime.
317
 
318
        * symfile.h:  New file, defining the interface between the
319
        generic and object-file-specific symbol reading code.
320
 
321
        * symtab.c:  Move generic symbol-reading interface to symtab.c,
322
        from dbxread.c, coffread.c, mipsread.c, etc.  Add symtab_fns
323
        table to map BFD targets to symbol-reading modules in GDB.
324
        Change index to strchr.
325
        (lookup_struct_elt_type):  Use error() rather than hand-made
326
        simulations thereof.
327
        (lookup_partial_symbol):  Speedup slightly when length == 0.
328
        (symbol_file_add):  New function.
329
        (symbol_file_command):  Call it.
330
        (symfile_open, symfile_init):  New function.
331
        (add_file_target_command, add_file_addr_command): moved from
332
        dbxread.c.
333
 
334
        * target.c (target_command):  use target_kill.
335
 
336
        * target.h (target_files_info):  Don't declare, never called
337
        from outside.
338
 
339
        * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
340
        files to determine stack end address.
341
 
342
        * valarith.c (value_x_binop, value_x_unop): Change error message
343
        to be more useful.  Pass proper argument to value_struct_elt.
344
 
345
        * valops.c (value_assign):  FIXME comment that long long
346
        bitfields will break here.
347
 
348
        * Makefile.dist:  Add symfile.h, remote-nindy.c, remote-eb.c.
349
        Update `make saber_gdb' to work better.
350
 
351
        * TODO:  A woman's work is never done.
352
 
353

Wed Dec 12 23:44:15 1990  John Gilmore  (gnu at cygnus.com)
362
 
363
        Continuing Intel 960 port merge of GDB.
364
 
365
        * Makefile.dist:  Merge i960 "nindy-share" files.  Rename
366
        malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
367
        Don't ship gdb.dvi in tar file.  Link gdb with init.o, not init.c.
368
        Wack over "make depend" so it handles files in subdirectories
369
        vx-share, nindy-share, bfd, and in the current directory.
370
 
371
        * blockframe.c (get_prev_frame_info):  Remove fatal error
372
        if stack not defined.
373
 
374
        * core.c (core_open, core_detach):  New functions that handle
375
        the old "core-file" command as "target core" and "detach" instead.
376
        (core_file_command):  Call them.
377
        (core_xfer_memory):  Use common routine xfer_memory.
378
 
379
        * dbxread.c:  Include a.out.gnu.h, not system a.out.h.
380
        dbxread now uses bfd for everything but symbol reading itself.
381
        BFD internals are used to drag out the relevant file offsets.
382
        (partial_symbol_file_open):  Change args all around for BFD.
383
 
384
        * symtab.c: Rename "value" to "val" everywhere, so we can
385
        #include "value.h".
386
        (symbol_file_command):  New command, moved from dbxread.c
387
        and coffread.c.  It uses BFD to read the file, then vectors
388
        based on its type, to dbx or coff symbol readers.
389
        * symtab.h:  Extern a few vars for symbol_file_command.
390
 
391
        * target.h:  Breakpoint takes a char * save area, not a char **.
392
 
393
        * valprint.c (val_print):  When unpacking bitfields, offset
394
        the address in gdb of the value, if it is declared with a shorter
395
        type.  Remove the last "runtime kludge test" of host byte order.
396
 
397
        * utils.c:  Remove old my_bfd_read routine.
398
 
399
        * stack.c (frame_info):  Use target_has_stack.  Print program counter
400
        register's actual name rather than "pc", since it's called the
401
        "ip" (instruction pointer) on the i960 (sigh).
402
 
403
        * target.c (target_command):  Add command for selecting a target
404
        type and calling its open routine.  This is used for initiating
405
        communication with a particular target, in a generic way.
406
 
407
        * tm-i960.h:  Update for modern gdb.  Remove semicolons from
408
        various macros.  Handle reading struct return convention, and
409
        error-out attempts to return structs with the "return" command.
410
        Be sure gdb doesn't think we know how to call functions in the
411
        inferior.
412
 
413
        * i960-tdep.c:  Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
414
        to i960_xxx in lower case.
415
        (arg_address):  Circumvent errors due to LOC_ARG_BLOCK
416
        not being defined yet.
417
 
418
        * remote.c (remote_open):  Call start_remote to initialize
419
        wait_for_inferior during open.
420
        (remote_xfer_inferior_memory):  Return length written rather
421
        than errno value.
422
 
423
        * remote-vx.c (target_command -> vx_open):  Use new generic
424
        target command.
425
        * remote-eb.c, inftarg.c, exec.c: ditto.
426
 
427
        * infrun.c:  Fix comments.
428
        (attach_program -> child_open):  Use new generic target command.
429
        (wait_for_inferior):  Clear saved register values before target_wait,
430
        so target_wait can set some of them if convenient.
431
 
432
        * infptrace.c (fetch_inferior_registers, store_inferior_registers):
433
        Return success indicator, not void.
434
        (child_xfer_memory):  Avoid fetching initial word if we'll
435
        overwrite it anyway.
436
 
437
        * infcmd.c (attach_command):  Use new generic target open routine.
438
        (_initialize_infcmd):  Update doc on attach and detach commands.
439
        (do_registers_info):  Merge in a byte-order problem as a FIXME
440
        comment.
441
 
442
        * findvar.c (find_saved_register):  Avoid problem in current frame.
443
        (read_relative_register):  Ditto.
444
        (write_register):  Convert byte order on the way out.
445
 
446
        * exec.c (file_command):  Add.
447
        (add_to_section_table, exec_command):  Use new bfd_map_over_sections.
448
        (xfer_memory):  Common function between core_xfer_memory and
449
        exec_xfer_memory.
450
        (exec_xfer_memory):  Use it.
451
 
452
        * pn-opcode.h:  Document that a "PN" is a Gould PowerNode.
453
 
454
        * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
455
        valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
456
        infcmd.c, i960-pinsn.c, eval.c, defs.h:  lint and gcc -Wall.

458
Sun Dec  2 16:45:06 1990  John Gilmore  (gnu at cygnus.com)
459
 
460
        Merge Intel 960 port of gdb, continuing...
461
 
462
        * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
463
        symbol_file_command):  Pass from_tty arg to hush 'em up.
464
 
465
        * coffread.c (symbol_file_command):  Avoid output if from_tty != 1.
466
        Add magic numbers for 960 COFF format.
467
 
468
Fri Nov 30 09:18:20 1990  John Gilmore  (gnu at cygnus.com)
469
 
470
        Merge Intel 960 port of gdb, from Intel "1.2" release.
471
 
472
        CHANGE_LOG entries from their port, which was based on
473
        gdb+-2.8.0:
474
 
475
    Thu Sep  6 11:02:22 PDT 1990
476
        Remove temp file if download is interrupted.
477
 
478
    Wed Aug  1 09:08:33 PDT 1990
479
        Now uses binary protocol to talk to NINDY.
480
        Old hex protocol (NINDY 2.13 and older) supported with -O switch.
481
        Times out after 5 seconds when trying to talk to NINDY.
482
 
483
    Tue May 29 12:54:49 PDT 1990
484
        Added variable baud rate (-b switch).
485
        Source code reorganization.
486
 
487
    Thu Apr 26 11:09:55 PDT 1990
488
        More cleanup of batch mode;  specifically, execute "-s", "-e", and
489
        "-se" switches as soon as they are encountered on the invocation line.
490
 
491
    Fri Apr 20 13:47:15 PDT 1990
492
        Add -brk switch.
493
 
494
    Thu Apr 19 09:54:28 PDT 1990
495
        Add 'reset' command.
496
 
497
    Wed Apr 18 09:48:07 PDT 1990
498
        After opening remote tty, wait for 1 second to go by without input
499
        from it before trying to talk to NINDY (fixes problems with the
500
        Heurikon HK80/V960E).
501
 
502
    Mon Apr  4 16:33:05 PDT 1990
503
        Some output was not being suppressed in 'batch' mode.
504
 
505
    Thu Mar 22 15:31:11 PST 1990
506
        Ask user if old symbol table should be deleted when new file is
507
        downloaded.
508
 
509
        Allow user to run a program downloaded before gdb960 was brought up.
510
 
511
        Correct "exec-file" help message for i80960 context.
512
 
513
        Correct bug in calculating user space address:  could occasionally
514
        corrupt user program.
515
 
516
        Make sure to zero low-order bits in rip's because of bug in 960CA
517
        A-step part:  could cause operation faults when "next"ing across
518
        a function call.
519
 
520
        Correct bug that made it impossible to get source line numbers for
521

525
 
526
    Fri Jan  5 12:14:42 PST 1990
527
        Correct disassembly (CA manual was right after all):
528
        opcode for sysctl is 0x659
529
 
530
    Mon Oct 23 12:03:04 PDT 1989
531
        Use G960BASE and G960BIN environment variables to find 'sx' utility.
532
 
533
    Mon Oct 16 14:15:09 PDT 1989
534
        "sfr0"-"sfr31" should have been named "sf0"-"sf31"
535
 
536
    Mon Oct  2 15:56:31 PDT 1989
537
 
538
        Added 960CA disassembly support.
539
 
540
        To simplify maintenance:
541
                - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
542
                        directly instead.
543
                - eliminated opcode.h: incorporates tables into i960-pinsn.c
544
                - moved 960-specific routines from i960-pinsn.c to i960-md.c
545
                - made disassembly interface identical to that in gdmp960.
546

548
 
549
Wed Nov 28 21:32:48 1990  John Gilmore  (gnu at cygint)
550
 
551
        * target.h: Allow targets to stack.  Add target_has_memory,
552
        _registers, etc.  Restructure memory access and "info files"
553
        to walk the target stack.
554
        * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
555
        target.c:  Change tables to match target.h.
556
        * inflow.c (child_mourn_inferior):  pop child_ops.
557
        (generic_mourn_inferior):  Use new has_stack flag.
558
        * infptrace.c (child_xfer_memory): New memory regime.
559
        * inftarg.c (child_files_info): New "info files" regime.
560
        * remote-eb.c: New memory regime, new info files.
561
        * remote-vx.c: New memory regime, new info files.  Now use
562
        separate targets for VxWorks attachment to machine, and
563
        actually running a process under VxWorks, since one has
564
        stack & execution & regs and the other doesn't.
565
        * remote.c: New memory regime, new info files.
566
        * sparc-xdep.c (fetch_core-registers):  New memory regime.
567
        * target.c:  New routines and support for stacked targets,
568
        new memory regime, new info files regime.
569
 
570
 
571
        Generalize section handling for an arbitrary number of sections,
572
        including use of the new BFD (binary file) library.
573
        * gdbcore.h: Add struct section_table.
574
        * exec.c (build_section_table):  Iterate all sections and
575
        record what gdb needs to know about them.
576
        (exec_command):  Use it.
577
        (exec_xfer_memory):  Use the table.
578
        (exec_files_info):  Print the table.
579
        * core.c (core_file_command, core_xfer_memory, core_files_info):
580
        Likewise.
581
        * source.c (find_source_lines):  Use bfd_get_mtime.
582
        * dbxread.c:  Quick changes to make it compile with new BFD.
583
        * utils.c (error):  Avoid using bfd_error in generic routines.
584
 
585
        * core.c (core_fetch_registers):  Get from the ".regs" section of
586
        the BFD core file.
587
        * sparc-xdep.c (fetch_core_registers):  Use the .regs info.
588
 
589
        * inferior.h (attach_flag):  Export.
590
        * infcmd.c (run_command):  use new target_create_inferior.
591
        * infrun.c (child_create_inferior):  Don't return result.
592
        * Makefile.dist (VERSION):  3.91.4.
593
 
594
Fri Nov 23 28:15:38 1990  John Gilmore  (gnu at cygint)
595
 
596
        * breakpoint.c (bpstat_num):  Handle breakpoints which have
597
        since been deleted, such as temporary breakpoints.
598
        infcmd.c (program_info):  ditto.
599
 
600
        * core.c (core_file_command):  Display the frame where the core
601
        dump occurred.
602
 
603
        * main.c:  lint.
604
 
605
        * remote-vx.c (target_command):  Merge in target command from
606
        targ-vx.c.  A few other cleanups.
607
 
608
        * TODO, Projects:  Lots more stuff to do...
609
 
610
Fri Nov 23 18:15:38 1990  John Gilmore  (gnu at cygint)
611
 
612
        Massive changes to wall off the remote-debugging interface
613
        behind a function vector.  The port to handle VxWorks targets
614
        is also part of this.
615
 
616
        All files:  Replace references to renamed functions,
617
        remove references to remote_debugging, remove references to
618
        have_include_file, have_core_file in favor of target_has_stack,
619
        target_has_memory, etc.
620
 
621
        * Modularize the breakpoint interface.
622
        breakpoint.h (BREAKPOINT_MAX):  New define sets max length of
623
        a breakpoint instruction.
624
        breakpoint.c: struct breakpoint's shadow_contents now sized as
625
        BREAKPOINT_MAX.
626
        (insert_breakpoints):  Vector to target to install breakpoints.
627
        (remove_breakpoints):  Vector to target here too.
628
        Remove REMOTE_SA_SPARC kludges and other remote_debugging.
629
        sparc-tdep.c (single_step):  Use new breakpoint interface for
630
        the single-step breakpoints.
631
        mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
632
        New file, contains routines to insert and remove breakpoints by
633
        reading out the old contents and later replacing them.  This is
634
        how ptrace breakpoints work, and many remote systems as well.
635
 
636
        * tm-vxworks68.h:  New config file, overrides a few things for
637
        Wind River's preferences.
638
 
639
        * target.h:  New file, for transfer vector used to talk to the
640
        inferior (child, attached, core, exec, remote, etc).  All accesses
641
        to the thing being debugged should come through these vectors.
642
        target.c:  New file, routines to handle transfer vector.
643
        (various files):  Add transfer vectors XXX_ops for the various
644
        targets and pseudo-targets (core files, etc) we support.
645
 
646
        * breakpoint.c (bpstat_stop_status):  Further explorations of
647
        watchpoints and why things don't work all the time.
648
        (bpstat_alloc):  New fn to allocate a bpstat and chain it.
649
 
650
        * config.gdb:  Only add "source ${srcdir}/.gdbinit" to
651
        the local gdbinit if it doesn't already have it.
652
 
653
        * core.c (core_ops):  add and install.
654
        Allow core debugging without exec file.
655
 
656
        * dbxread.c (free_and_init_header_files):  Merge two fns.
657
        (end_symtab):  Free named symbol table when a new version comes in.
658
        (read_dbx_symtab):  Relocate all kinds of symbols with base
659
        address.  First step toward handling different text, data, bss
660
        reloc.
661
        (add_file_addr_command):  Renamed add_file_command.
662
        (add_file_command):  Vector to remote handler.
663
        Add "load" as an alias for "add-file" command.
664
 
665
        * defs.h:  Allow "volatile" to be used in non-ANSI; use it for
666
        non-returning functions.
667
 
668
        * exec.c:  Add exec_ops, and push it as a target when an exec
669
        file is specified.
670
 
671
        * infcmd.c (run_command):  Pass executable file name and arg list
672
        separately when starting an inferior.  Permit "run" when no exec
673
        file is specified, for VxWorks.
674
        (detach_command):  Move to child_detach in inftarg.c.
675
 
676
        * inftarg.c:  New file.  Unix-child-specific routines, and the
677
        child_ops structure.
678
 
679
        * inferior.h (registers):  Export "registers" as the way for
680
        target dependent register handlers to find gdb's local copy of
681
        the registers.  Rename "stop_after_attach" to "stop_soon_quietly"
682
        since it is now used by places that want wait_for_inferior to
683
        handle the grunge but want to see every trap from the inferior.
684
 
685
        * inflow.c (create_inferior):  Pull out, and merge into infrun.c.
686
        Eliminate remote_debugging hooks in terminal handling.
687
 
688
        * infrun.c:  Replace start_inferior with child_create_inferior.
689
        Move all the hair of Unix shells and ptrace idiosyncracies into
690
        child_create_inferior, so remote handlers don't have to deal.
691
        Remove running_in_shell.  Rename stop_after_attach to
692
        stop_soon_quietly, and use it in a few other places where we want
693
        to just call wait_for_inferior and get control back on the first
694
        trap.  trap_expected now never takes a value > 1.
695
        (init_wait_for_inferior):  Initialize static vars when a new
696
        process is created.
697
 
698
        main.c (gdbinit):  Add new hook for .gdbinit file name, let
699
        it be overridden by config files as GDBINIT_FILENAME.
700
        (DEFAULT_PROMPT):  Add new hook for overriding (gdb) prompt.
701
        Both of these are used for VxWorks gdb.
702
 
703
        mcheck.c:  rename include file "gmalloc.c" to avoid problems
704
        with system include file "malloc.c".
705
 
706
        param-no-tm.h:  New include file, same as param.h but does not
707
        include the default "tm.h" file.  This is used in files where
708
        the target is known, e.g. remote-eb.c or sparc-xdep.c.
709
 
710
        param.h:  Now just a shell that includes tm.h and param-no-tm.h.
711
 
712
        remote-vx.c:  New file, VxWorks remote debugging support.  Uses
713
        RPC routines that are shared with the target system, in directory
714
        ${srcdir}/vx-share.
715
 
716
        remote.c:  Vectorize remote interface.
717
 
718
        source.c:  Globalize source_path, and make an alias "l" for "list"
719
        since we now have the "load" command.
720
 
721
        sparc-xdep.c:  Use new param-no-tm.h.
722
 
723
        symmisc.c (free_named_symtab):  Add new function from Wind River.
724
        However, ifdef it out for now while we think about what it should
725
        really be doing.
726
 
727
        tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
728
        PREPARE_TO_STORE to
729
        the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
730
        non-Unix-children handle this with their own code in the target
731
        transfer vector.
732
 
733
        Makefile.dist:  Roll version to 3.92.3.  Add vx-share stuff to
734
        source and target lists.  Add vx-share to default list of include
735
        directories.  Add new files to src and target lists: mem-break,
736
        target, inftarg, remote-eb, remote-vx, targ-vx.  Be sure the
737
        ${srcdir} versions of munch and createtags are used.
738
 
739
        * valops.c (find_function_addr):  Split out of call_function.
740
        (call_function_by_hand):  Rename call_function; this function
741
        calls functions in the target by laboriously patching the target
742
        word-by-word with the right stack, args, regs, etc.
743
 
744
 
745
Mon Nov  5 17:29:10 1990  John Gilmore  (gnu at cygint)
746
 
747
        Handle AMD 29000 a bit better.
748
 
749
        * remote-eb.c (readchar):  Mask received char log to make it readable.
750
        (remote_start):  Pass arguments down to executing program.
751
        Make startaddr unsigned.
752
        infrun.c (start_inferior):  Accept args, pass them to
753
        remote_start.
754
        infcmd.c (run_command):  Pass args down to start_inferior.
755
 
756
        * tconfig/am29k-aout, tconfig/am29k-coff:  New files specifying
757
        the target object file format.
758
        tm-29k.h:  Pay heed to COFF_ENCAPSULATE.
759
 
760
        * am29k-pinsn.c (print_insn):  Print 0x on hex numbers in disassembly.
761
        am29k-tdep.c (examine_prologue):  Better checking of function prefixes.

764
 
765
        * Makefile.dist (VERSION):  Roll version to 3.91.9 and freeze.
766
        * TODO:  We did a few things, we have more to do though.
767
 
768
        * xm-sparc.h (CLEAR_DEFERRED_STORES):  Define.
769
        * inflow.c (inferior_died):  Clear deferred stores.
770
 
771
        * Debug problems with dummy frames and calls to the inferior.
772
        * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME):  Move to sparc-tdep.c.
773
        * sparc-tdep.c (do_restore_insn):  Simplify.
774
        (sparc_frame_find_saved_regs):  Simplify and fix what we find.
775
        (sparc_push_dummy_frame):  Simplify and fix what we push.
776
        (sparc_pop_frame):  Slightly more hair here, deciding whether
777
        we are restoring a saved PC or returning to a return address in %i7.
778
        * sparc-xdep.c (read_inferior_registers):  Debug if valid reg is read.
779
 
780
        * utils.c (xmalloc, xrealloc):  Return type depends on __STDC__.
781
        * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
782
        * obstack.h (chunkfun): ditto.
783
        * defs.h (xmalloc, xrealloc): ditto
784
 
785
        * utils.c (quit):  Grab the terminal from the child if necessary.
786
 
787
        * inflow.c (term_status_command): Rename to term_info, change
788
        to "info terminal".
789
 
790
        * sparc-pinsn.c (print_insn):  Disassembly prefers real instructions.
791
        (is_delayed_branch):  Speed up.
792
        * sparc-opcode.h: Add ALIAS bit to aliases.  Fix up opcode tables.
793
        Still missing some float ops, and needs testing.
794
 
795
        * Support for input and output radixes other than base 10
796
        * defs.h (input_radix, output_radix):  Declare.
797
        * expread.y (yyparse, parse_number):  Handle changes of input
798
        radix, and ambiguous names-or-numbers in radixes >10.
799
        * printcmd.c (print_scalar_formatted):  Print formatted hex
800
        numbers in varying column widths.
801
        * valprint.c (val_print):  Use output_format to print scalar ints.
802
        (set_input_radix, set_output_radix, set_radix):  Create.
803
        (set_output_radix):  Set output_format from output_radix.
804
        (_initialize_valprint):  add `set radix' but leave the others off.
805
 
806
        * main.c (execute_command): Let stupid questions be turned off.
807
        (_initialize_main): Handle "set stupidity", etc.
808
 
809
        * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
810
        sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c:  Lint.
811
 
812
Tue Oct  2 11:20:02 1990  John Gilmore  (gnu at cygint)
813
 
814
        * TODO, Makefile.dist, ChangeLog:  Freeze for 3.91.8 release.
815
        bfd stuff is still screwed up, but with some manual work, it
816
        compiles.
817
 
818
        * breakpoint.c (bpstat_do_actions):  Start over if a command
819
        proceeds the inferior, since the inferior will have stopped and
820
        will need to have its new stop-actions taken care of.
821
 
822
        * dbxread.c (read_struct_type):  Expression gives Sun3 4.0.3
823
        compiler fits, simplify it.
824
 
825
        * gdb.texinfo (directory command): Doc new dir command.
826
        source.c (directory_command):  "dir" now puts things on the front
827
        of the path, moves dups up front, and handles multiple names
828
        on the command line, inserting each one in order.  It also
829
        blows away cached line and full_filename info.
830
 
831
        * stack.c (backtrace_command):  Skip "more stack frames follow"
832
        unless interactive.
833
 
834
        * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
835
        xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
836
        xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
837
        The only odd one was Gould NP1, which had defined vprintf to
838
        "printf"!!!
839
 
840
        * Merge Ted Goldstein 's changes for epoch.
841
        printcmd.c (print_command_1): Pass 'inspect' flag down as a global
842
        variable, inspect_it.
843
        valprint.c (print_string, val_print): Use the global inspect_it
844
        to indicate whether to print in Epoch style or normal style.
845
 
846
Mon Oct  1 23:55:26 1990  John Gilmore  (gnu at cygint)
847
 
848
        * printcmd.c (call_command):  add an alias for the "print" command
849
        which runs expressions and doesn't print the result if void.
850
        (print_command_1): implement it.
851
 
852
        * command.c: Remove #if 0'd code.  Initialize all the fields
853
        in add_cmd ().  Rename do_nothing_command to
854
        not_just_help_class_command, and make it externally visible.
855
        command.h: add user_commands to struct.
856
        * main.c (define_command):  Don't overload c->function with a char
857
        string as well as a function pointer.
858
 
859
        * eval.c (evaluate_subexp):  Reinstall tiemann changes to
860
        calling convention of value_struct_elt () that got dropped in
861
        merge.
862
 
863
        * tm-sparc.h (FRAME_FIND_SAVED_REGS):  move to sparc-xdep.c.
864
        sparc-tdep.c (sparc_frame_find_saved_regs):  ditto.
865
 
866
        * tm-sparc.h (POP_FRAME): replace some constants with defines.
867
 
868
        * sparc-xdep.c (store_inferior_registers):  defer stores to regs
869
        until a good time (e.g. when we are about to run the child),
870
        saving ptrace calls.
871
        * infrun.c (proceed):  handle DO_DEFERRED_STORES.
872
        * tm-sparc.h: define DO_DEFERRED_STORES.
873
 
874
        * sparc-xdep.c (store_inferior_registers): when storing float
875
        registers, don't store stack regs too.  When storing the SP,
876
        however, DO store the stack regs too.  This fixes a bug in which
877
        the dummy frame is not recognized when a call_function finishes,
878
        because its frame pointer (in the stack regs) was never
879
        initialized.
880
        (read_inferior_registers):  Mark WIM and TBR and FPS and CPS valid
881
        even though we don't know how to read them from an inferior.
882
        valops.c (call_function):  Comment about storing SP.
883
 
884
        * infrun.c (save_inferior_status): Save away the original bpstat
885
        chain so it can be restored later.  Install the copied version for
886
        use by whoever saved the status.  It will be blow away by
887
        restore_inferior_status, and the original chain restored.  This is
888
        important for people who have pointers into the original.
889
 
890
        * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
891
        findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
892
        main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint

895
Fri Sep 28 20:32:46 1990  John Gilmore  (gnu at cygnus.com)
896
 
897
        * Makefile.dist: Roll version to 3.91.8.  Add bfd.h and bfdconfig.h
898
        temporarily to the makefile.  Add am29k-opcode.h and WHATS.NEW.
899
        Add stuff.c and kdb-start.c to the OTHERS list for tar files.

902
 
903
        * Merge Mike Tiemann's multiple inheritance changes from Sun.
904
        Store the baseclasses in a type struct starting from array element
905
 
906
 
907
        dbxread.c: the above.
908
        (virtual_context): Add
909
        Read new debug information about which virtual function table
910
        a virtual function is from, and store it in fn_field.fcontext.
911
 
912
        symtab.h: Add fcontextt.  Fix baseclass indices.  Typo in
913
        TYPE_FN_FIELD_STATIC_P.
914
 
915
        symtab.c: the above.
916
        valops.c: the above.  Handle pointer casts of object *'s.
917
        (search_struct_method): Add.
918
        (value_struct_elt): First arg is now a pointer to a value, and is
919
        modified on return.
920
 
921
        valprint.c: the above.
922
        values.c (value_virtual_fn_field): Add type arg.  Handle
923
        offsetting to the proper object when calling virtual fns.
924
        The above.
925
        (baseclass_addr): Add valuep arg.
926
 
927
        * README:  Document the current state of BFD config (missing).
928
        * TODO, ChangeLog, Makefile.dist: Roll version.
929
        * WHATS.NEW: Add summary of changes since 3.5.
930
 
931
Thu Sep 27 16:23:12 1990  John Gilmore  (gnu at cygint)
932
 
933
        * dbxread.c (read_struct_type): Clear bit vectors whenever
934
        we allocate one.
935
        symtab.c (B_CLRALL): define.
936
 
937
        * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
938
        using == rather than =.  Huh...  This fixes the dreaded problem
939
        wherein builtin_type_int becomes TYPE_CODE_FLT.
940
 
941
        * core.c (info_files): Show the inferior pid.
942
 
943
        * config.gdb: Avoid putting "dir" command into .gdbinit.  GDB
944
        already knows how to look in the source directory.
945
 
946
        * Remove psymtab hair from many places.  Remove duplicated code
947
        for searching symbol tables.  Hide psymtabs from most places.
948
        Make it fast to get from a psymtab to its symtab.
949
 
950
        blockframe.c (blockvector_for_pc): Remove psymtab hair.
951
        coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
952
        mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
953
        dbxread.c: export psymtab_to_symtab, make it work if called N times.
954
        (psymtab_to_symtab): Rename to psymtab_to_symtab2.  Initialize
955
        new symtab completely.  New psymtabs get symtab pointer
956
        initialized to zero.  Remove MI warning printf.
957
        symtab.h: Comments.  Add psymtab to symtab pointer.
958
        (PSYMTAB_TO_SYMTAB): New macro.
959
        symtab.c: use PSYMTAB_TO_SYMTAB.  Add psymtab_to_symtab and export it.
960
        source.c: use PSYMTAB_TO_SYMTAB.  Remove symtab version and
961
        compilation fields.
962
        stack.c (backtrace_command): Avoid pre-pass to read symbols, if
963
        verbose is not set.
964
        (print_frame_info): Avoid special-casing symbols that have not yet
965
        been read in.
966
 
967
        * source.c (open_source_file): Quick path if we have already
968
        located the source file by its full name.
969
 
970
        * symtab.c (lookup_symbol): Use find_pc_symtab rather than
971
        find_pc_psymtab.  When a name is found in the misc function
972
        vector, search the symbol table for its mangled name, not the
973
        name that the user typed.
974
 
975
        * bfd.h: Fix missing comment terminators, make #endifs match.
976
 
977
        * valarith.c (value_less): Handle unsigned int comparisons.
978
        Add FIXME about pointer compares, which assume host and target
979
        pointers are the same.
980
 
981
        * command.c (do_nothing_command): lint
982
        dbxread.c: lint.  Remove sort_syms.  Document C++ visibility info,
983
        fix comments on debug symbol format for visibility.  Actually set
984
        visibility of symbols.
985
        main.c (echo_command): lint; use .
986
        tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
987
        obstack.h (_obstack_blank): Rearrange pointer math to avoid
988
        pointing past end of allocated memory; saber complains.
989
        obstack.h: Declare the external functions that we use.
990
        valarith.h: use 
991
        solib.c (solib_add): lint.
992
 
993
Fri Sep 21 17:05:19 1990  John Gilmore  (gnu at cygint)
994
 
995
        * main.c (initialize_main):  Default info_verbose to off, now that
996
        symbol reading is fast.
997
        (quit_command):  Avoid clobbering exec_bfd while quitting.
998
 
999
        * Initial BFD (binary file diddling library) merger:
1000
        coffread.c: Change AOUTHDR to struct exe_hdr.
1001
        dbxread.c: ditto.
1002
        core.c: initialize initialized data at compile time.
1003
        (core_file_command):  Move from coredep.c, convert to bfd.
1004
        (xfer_core_file): Convert to bfd.
1005
        exec.c (exec_file_command): use bfd routines.
1006
        gdbcore.h: BFD.
1007
        mips-tdep.c: Remove exec_file_command and friends.
1008
        source.c: bfd.
1009
 
1010
        * coredep.c: (fetch_core_registers) Convert core_file_command to
1011
        fetch_core_registers.
1012
        mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
1013
 
1014
        * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
1015
        (my_bfd_read): More bogosity, which I don't think we call.
1016
        (program_name): Remove this atrocity asap!
1017
 
1018
Wed Sep 19 13:36:41 1990  John Gilmore  (gnu at cygint)
1019
 
1020
        * From Per Bothner:
1021
        values.c: allocate_repeat_value was not clearing the
1022
        optimized_out field.
1023
        (value_static_field): minor stylistic fix (wrong macro was used).
1024
        valops.c (value_struct_elt_for_address): didn't work for C++
1025
        static fields.
1026
 
1027
        * signame.c (_initialize_signame):  Initialize signal names once.
1028
 
1029
        * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
1030
        exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
1031
        symtab.h, tm-29k.h, valprint.c, value.h, values.c:  Lint.
1032
 
1033
        * remote-eb.c:  Support user-settable baud rates on the serial port.
1034
 
1035
        * tm-sun3.h (PREPARE_TO_STORE): fix typo.
1036
 
1037
Fri Sep 14 13:28:29 1990  John Gilmore  (gnu at cygint)
1038
 
1039
        * tconfig/sun3os4: Remove warning about native assembler,
1040
        since it also occurs in the xconfig file.
1041
 
1042
        * findvar.c (registers): Allocate some slop after `registers'
1043
        to prevent stray accesses from trashing the next variable.
1044
 
1045
        * tm-68k.h (REGISTER_BYTES):  Allocate the right number of bytes
1046
        on the sun-3, by changing the #ifdef from `sun3' (which is not
1047
        defined by cc) to `sun'.  Symptom was trashed builtin_type_XXX
1048
        vars, which happened to follow `registers' in the executable.
1049
 
1050
        * readline/history.c (history_search): Heed gcc-2's advice
1051
        and parenthesize && inside ||).
1052
 
1053
        * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
1054
        tm-29k.c:  Insert FSF copyright headers.
1055
 
1056
        * remote-eb.c:  Better comments.
1057
 
1058
        * Makefile.dist:  Update to 3.91.6.
1059
        * TODO: note PREPARE_TO_STORE problem.
1060
 
1061
Thu Sep 13 09:52:33 1990  Jim Kingdon  (kingdon at cygint)
1062
 
1063
        * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
1064
 
1065
        * remote.c:  Wrap the whole file in #if !defined (SPECIAL_REMOTE).
1066
 
1067
        * infrun.c (wait_for_inferior, at end): Don't set up
1068
        prev_* if the inferior no longer exists.
1069
 
1070
        * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
1071
        CANNOT_EXECUTE_STACK.
1072
        valops.c (call_function): Use it.
1073
 
1074
        * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
1075
 
1076
        * inferior.h (PC_IN_CALL_DUMMY): New macro.
1077
        infrun.c (wait_for_inferior, 2 places): Use it.
1078
 
1079
        * values.c (value_being_returned): Only use
1080
        EXTRACT_STRUCT_VALUE_ADDRESS if defined.
1081
 
1082
        * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
1083
        right thing for remote-eb.c.
1084
 
1085
        * sun3-xdep.c:  Remove extraneous call to remote_store_registers.
1086
        * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c:  Ditto.
1087
 
1088
        * blockframe.c:  Put get_frame_saved_regs inside #if !defined
1089
        (FRAME_FIND_SAVED_REGS).
1090
 
1091
        * findvar.c ({fetch,store}_registers): Check for
1092
        REMOTE_{FETCH_STORE}_REGISTER macro.
1093
 
1094
        * findvar.c (get_saved_register): Add argument lval and
1095
        change meaning of argument addr.
1096
        findvar.c:  Change calls to get_saved_register to reflect
1097
        new calling convention.
1098
        valops.c (value_assign): Use get_saved_register instead of
1099
        find_saved_register.
1100
 
1101
Sun Sep  2 12:40:20 1990  Jim Kingdon  (kingdon at cygint.cygnus.com)
1102
 
1103
        * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
1104
        an (uninitialized) pointer to one.  Use "&" when passing it
1105
        to fread.
1106
 
1107
Fri Aug 31 22:57:54 1990  Jim Kingdon  (kingdon at cygint.cygnus.com)
1108
 
1109
        * coffread.c (getfilename): Use DGUX x_offset and x_name if
1110
        defined.
1111
 
1112
        * coffread.c (symbol_file_command): Put semicolon after
1113
        "int from_tty".
1114
        Put safe_to_init_tdesc_context in #if defined (TDESC).
1115
        Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
1116
        coffread.c: #include .
1117
        (read_coff_symtab): Typo: in_source_files -> in_source_file.
1118
        Add missing ')' in check for "lc%" and friends.  Remove
1119
        extraneous '}'.
1120
        Declare read_one_sym() at top of file.
1121
        (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
1122
        MC68WRMAGIC can have the same value without causing a duplicate
1123
        case.
1124
 
1125
Thu Sep 13 15:55:36 1990  John Gilmore  (gnu at cygint)
1126
 
1127
        * Allow a Makefile to be built without building the
1128
        tm and xm file links that screw up builds in subdirectories.
1129
        This is done with `config.gdb none', then you can do things
1130
        like `make gdb.tar.Z'.
1131
        * tconfig/none: Config file for no target system
1132
        * xconfig/none: Config file for no host system
1133
        * config.gdb: If no TM or XM files are called out by the
1134
        host or target file, don't make links for them.
1135
 
1136
        * cplus-dem.c: Add documentation.
1137
 
1138
        * dbxread.c (read_ofile_symtab): Turn a fatal error into a
1139
        simple error, so the user's gdb doesn't crash due to some object
1140
        file problem (e.g. somebody is rebuilding the file out from under
1141
        gdb).
1142
 
1143
        * printcmd.c (print_address_symbolic): demangle the symbol.
1144
 
1145
        * Makefile.dist (OTHERS): Remove tdesc-lib because it has
1146
        Motorola copyrights in it.  Make "make gdb.tar.Z" work.
1147
        (alldeps.mak): sort and uniq all results from this; duplicates
1148
        hose gdb.tar.Z link building.  Remove RCS files from
1149
        tconfig and xconfig.  Add config files for sun386.  Add
1150
        a few odd files to OTHERS and HFILES.
1151
 
1152
Mon Sep 10 21:20:24 1990  John Gilmore  (gnu at cygint)
1153
 
1154
        * Makefile.dist: Pull solib.c to tconfig/sun?os4.
1155
        Roll version number to 3.91.5.  Make lint work in bindir.
1156
 
1157
        * README:  Document cross-debugging and new file structure.
1158
 
1159
        * blockframe.c: Lint.  Include "value.h" to declare read_register.
1160
        (find_pc_partial_function): remove duplicate line.
1161
 
1162
        * command.h: Lint.  Declare error_no_arg and dont_repeat.
1163
 
1164
        * tm-news.h: Remove inadvertently duplicated stuff.
1165
 
1166
        * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
1167
        Clean up usage of misc_function_type.  Declare some CORE_ADDRs.
1168
 
1169
        * config.gdb: Allow `config.gdb host target' form.  Clean
1170
        up previous change that printed bogus messages when you just said
1171
        `config.gdb'.
1172
 
1173
        * core.c: #include "command.h" for lint.
1174
        * dbxread.c: lint
1175
        * eval.c: lint
1176
        * main.c: Remove some casts of enums.  Lint.
1177
        * source.c: lint
1178
        * symtab.c: lint
1179
        * symtab.h: lint
1180
        * expread.y: lint
1181
        * valarith.c: lint
1182
 
1183
        * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
1184
 
1185
        * sparc-tdep.c (isannulled): Take instruction as parameter, don't
1186
        read it from memory.  This will allow us to save ptrace calls
1187
        eventually.   Changed caller single_step too.
1188
 
1189
        * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
1190
        that we aren't going to use, saving many ptrace calls, especially
1191
        when watchpointing or single stepping.  Use some #define's for
1192
        constants.
1193
        (store_inferior_registers): Ditto.
1194
        (core_file_command): Use some #define's for constants.
1195
 
1196
        * tm-sparc.h: Add #define's for some register numbers, so we
1197
        can eliminate the use of random constants in sparc-xdep.c.
1198
 
1199
        * stack.c (frame_command, print_frame_info, up_command,
1200
        down_command) Remove frame_changed, since it
1201
        causes a bug and doesn't seem to do anything useful.  In some
1202
        places it was used as a flag, in others as a stack level (?).
1203
 
1204
        * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
1205
        default is to use the portable (vprintf) version rather than the
1206
        kludge version.
1207
        * xm-news.h (MISSING_VPRINTF): Add.
1208
 
1209
        * valprint.c (val_print): Demangle fancy vtbl printouts.  Lint.
1210
 
1211
Sat Sep  8 00:24:12 1990  John Gilmore  (gnu at cygint)
1212
 
1213
        * Remove stuff that forces -Bstatic linking of gdb, and warnings
1214
        about linking debugged programs -Bstatic in the sun?os4 config
1215
        files in tconfig and xconfig subdirectories.
1216
 
1217
        * main.c (main):  Remove unreached exit(0) now that we exit
1218
        via quit_command().
1219
 
1220
        * Create TODO file for online bug list.  There are too many
1221
        "little" bugs to keep track of on paper.
1222
 
1223
        * Change Projects file to refer to bug-gdb@cygnus.com
1224
        rather than kingdon@ai.
1225
 
1226
Fri Sep  7 23:35:15 1990  John Gilmore  (gnu at cygint)
1227
 
1228
        * Makefile.dist (VERSION): 3.91.4 now.
1229
 
1230
        * symtab.c (init_misc_bunches): Rename from init_misc_functions.
1231
        (condense_misc_bunches): Add sanity check that misc_count is
1232
        the same as the number of symbols in the bunch.
1233
 
1234
        * coffread.c: rename init_misc_bunches.  Pass an argument
1235
        to condense_misc_bunches (a zero).
1236
 
1237
        * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
1238
        every time we are called; don't rely on our caller to do it.
1239
        (add_file): Remove call to init_misc_bunches.
1240
 
1241
        * mipsread.c: Only warn, don't error, if unknown symbol types.
1242
        This keeps an old gdb from falling on its face if it sees newly
1243
        extended symbol info.  Rename init_misc_bunches.
1244
 
1245
Fri Sep  7 22:58:15 1990  John Gilmore  (gnu at cygint)
1246
 
1247
        * Merge in changes from Per Bothner for DECstations and other
1248
        MIPS stuff.  The rest is Bothner speaking:
1249
 
1250
        The next message is a merger of Alessando Forin's mips port with
1251
        mine.  I've tried to use my good if biased judgment to get
1252
        the best of both. It *does* need testing.
1253
 
1254
        Some of the changes are general, *not* mips-specific.
1255
 
1256
        param.h:
1257
        Didn't believe in little-endian bit order.
1258
        There are still inconsistencies about whether flags
1259
        like BITS_BIG_ENDIAN are integer (#if ...) or
1260
        boolean (#ifdef ...). I tried to paper over them.
1261
 
1262
        dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
1263
        Moved some misc_function code that was common to
1264
        {dbx,coff,mips}read.c to symtab.c.
1265
        In the process, I think I cleaned things up a bit.
1266
        At the same time, moved obsavestring and obconcat to symtab.c.
1267
 
1268
        dbxread.c:
1269
        Removed obsolete condense_addl_misc_bunches (use
1270
        condense_misc_bunches(1) instead).
1271
 
1272
        exec.c:
1273
        Needed to include , at least on DECstations.
1274
 
1275
        valops.c, mips-tdep.c, tm-mips.h:
1276
        Added PUSH_ARGUMENTS macro to support funny argument-pushing
1277
        conventions (when STACK_ALIGN is insufficient).
1278
        Needed on mips, where doubles need 8-byte alignment,
1279
        but ints only need 4.
1280
 
1281
        mips-opcode.h:
1282
        Removed cruft that was not being used.
1283
        Merged in many fixes (most from Frank Yellin, fy@lucid.com).
1284
 
1285
        mips-pinsn.c:
1286
        Print $ before register-names (I think that makes things a little
1287
        more consistent).
1288
        Never print two instructions, even if one delays.
1289
        Removed hex-disassemble set_cmd.  (This is not mips-specific,
1290
        so I think the argument is whether it is generally worthwhile or not.
1291
        I'm inclined to think not, given how easy it is to
1292
        convert between radixes in gdb.)
1293
 
1294
        mipsread.c:
1295
        This is basically Alessando's code.
1296
        It doesn't use obstacks; I changed it to use obstacks
1297
        in a few minor places where using malloc causes a
1298
        memory leak. (Probably, more places could/should be changed.)
1299
        I added record_misc_function where it was missing.
1300
        In symbol_file_command and add_file_command, I tried
1301
        to make the code consistent with more recent versions.
1302
        Minor sylistic changes in parse_procedure.
1303
        Make a .gdbinfo. psuedo-symbol point back to the real
1304
        procedure symbol (using the isym field).
1305
 
1306
        mips-tdep.c:
1307
        This is basically from my port, but with a lot of details
1308
        and a number of routines merged in from Alessando's version.
1309
        I basically used my code "raw" backtrace (use heuristics
1310
        from the actual code, rather than symbol table info) - though
1311
        the idea is Alessandro's. I feel my code is a little cleaner
1312
        here, particularly in being a little more flexible, such as being
1313
        able to handle gcc-produced code (which it now can).
1314
        It also doesn't do frame caching (which is not useful
1315
        more recent gdb versions).
1316
        I also used my code for push_/pop_dummy, more or less.
1317
        I tried to incorporate AF's code for testing sigtramp
1318
        while backtracing; I probably got it wrong.
1319
        Added mips_print_register, which tries to scrunch as much
1320
        information as possible on a screen...
1321
        Removed the skip-prologue set_cmd. As with hex-disassemble (see
1322
        under mips-pinsn.c), I don't see anything mips-specific here,
1323
        and I don't see it being all that useful anyway.
1324
 
1325
        tm-mips.h:
1326
        Added a $fp psuedo-reg distinct from $fp (nice for gcc).
1327
        Use more register names (rather than hard-cases numbers).

Thu Sep  6 18:33:15 1990  John Gilmore  (gnu at cygint)
1330
 
1331
        * Hack up 3.90.11 changes:
1332
 
1333
        * Makefile.dist (depend): parameterize $(GCC).
1334
        Add solib.c and solib.o.
1335
        (readline): Fix vpath for both absolute or relative SRCDIR.
1336
 
1337
        * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
1338
        Also, let the part I didn't understand at least compile so
1339
        I can test the rest.  FIXME.
1340
 
1341
        * dbxread.c: Fix thinko using strcmp.
1342
        (init_psymbol_list): declare static.
1343
        (partial_symbol_file_open): Comment cleanups better, avoid
1344
        cleaning up the string table since the caller will do that.
1345
        Move the stat for mod time into symbol_file_command, temporarily.
1346
        (There should be a mod time for each symbol file, eventually,
1347
        to control its rereading.  FIXME.)
1348
 
1349
        * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
1350
        SunOS, which gives error for shared libs otherwise.  (From
1351
        Schaefer, probably FIXME needs work for portability.)
1352
 
1353
        * solib.c:  Move #include "param.h" to work.
1354
        Lowercase all the Uppercase Letters In the Messages.
1355
        (find_solib): Clean up inferior_so_name for debug printouts.
1356
        Allow no argument, to mean all shared libraries.
1357
 
1358
        * symmisc.c: include param.h to get CLEAR_SOLIB.
1359
 
1360

1391
 
1392
        * Changes for Sun shared libraries:
1393
        blockframe.c (find_pc_partial_function): If a non-text symbol
1394
        is found, set *address = pc - FUNCTION_START_OFFSET.
1395
        breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:

1402
        dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
1403
        (record_misc_function): Give correct type for N_DATA symbols.
1404
        (condense_misc_bunches): do "misc_function_count = j" regardless
1405
        of inclink.
1406
        Take code which is shared between symbol_file_command and
1407
        add_file_command and put it into partial_symbol_file_{open,read}.
1408
        Split add_file_command into add_file_command and add_file.
1409
        Make psymtab_to_symtab read in the string table if the file
1410
        is not symfile.
1411
        Two new parameters to read_dbx_symtab and start_psymtab.
1412

1413
 
1414
Tue May 22 17:43:03 1990  Jim Kingdon  (kingdon at pogo.ai.mit.edu)
1415
 
1416
        * infcmd.c: Change cont_command to continue_command and "cont"
1417
        to "continue".
1418
 
1419
Mon May 21 14:41:41 1990  Jim Kingdon  (kingdon at pogo.ai.mit.edu)
1420
 
1421
        * breakpoint.c (enable_breakpoint): Get value of watchpoint.
1422
 
1423
        * defs.h [sparc]: Use  regardless of __GNUC__.
1424
 
1425
        * values.c (USE_STRUCT_CONVENTION): Check for structures of
1426
        size 1,2,4,8 rather than size < 8.
1427
 
1428
        * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
1429
        as necessary, not just once.
1430
 
1431
        * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
1432
 
1433
Thu May 17 15:04:09 1990  Jim Kingdon  (kingdon at pogo.ai.mit.edu)
1434
 
1435
        * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
1436
 
1437
        * tm-news.h: Add CALL_DUMMY_*.
1438
 
1439
        * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
1440
 
1441
        * config.gdb: In list_host, list_target, use ${i}, not $i.
1442
 
1443
Tue May 15 21:27:12 1990  Jim Kingdon  (kingdon at pogo.ai.mit.edu)
1444
 
1445
        * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
1446
 
1447
        * sparc-opcode.h: Change all store floating-point state register
1448
        instructions to have the right match & lose fields.
1449
 
1450
Sat May  5 12:39:18 1990  Jim Kingdon  (kingdon at pogo.ai.mit.edu)
1451
 
1452
        * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
1453
        VPATH to readline.
1454
        config.gdb: If srcdir != ., create readline directory and
1455
        copy a makefile into it.
1456
 
1457
        * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
1458
        consistency with POSIX.
1459
 
1460
        * breakpoint.c (bpstat_stop_status): Disable watchpoint
1461
        when we exit its exp_valid_block.
1462
 
1463
Tue Sep  4 11:46:46 1990  John Gilmore  (gnu at cygint)
1464
 
1465
        * Makefile.dist: Bump version to 3.91.3.
1466
 
1467
        * Clean up handling of breakpoint commands (somewhat).
1468
          Prompted by Tiemann bug report "cont 10" doesn't work any more.
1469
 
1470
          inferior.h: Add breakpoint_proceeded to inferior status struct
1471
          and globals; save it and restore it.
1472
          (clear_breakpoint_commands): Cleanup, remove old #define.
1473
 
1474
          infrun.c (clear_proceed_status): Set breakpoint_proceeded.
1475
          (save_inferior_status, restore_inferior_status): handle it also.
1476
          (proceed): Remove earlier code that set breakpoint_proceeded.
1477
          It is now set only in clear_proceed_status.
1478
          (clear_proceed_status): Cleanup, use bpstat_clear rather
1479
          than clear_breakpoint_commands.  No callers need the stop_bpstat
1480
          between clear_proceed_status and proceed.
1481
 
1482
          infcmd.c: Add breakpoint_proceeded definition and comment.
1483
          (cont_command, jump_command, signal_command): Move call to
1484
          clear_proceed_status right next to call to proceed.
1485
 
1486
          breakpoint.c (bpstat_do_actions): Avoid clobbering our
1487
          caller's argument while running down the chain of breakpoints.
1488
          Use new variable "breakpoint_proceeded" to determine when
1489
          a command that it executes moves the inferior past the
1490
          breakpoint.
1491
          (bpstat_clear): Handle NULL argument.
1492
          (bpstat_clear_actions): Avoid useless call to
1493
          breakpoint_auto_delete.
1494
          (delete_breakpoint):  Clean up bpstat's that are pointing to
1495
          the deleted breakpoint from the stop_bpstat chain.
1496
          (breakpoint_auto_delete): Simplify.
1497
 
1498
        * Clean up handling of EOF, error on stdin, etc.  This was
1499
          prompted by a network problem that caused gdb to go into an
1500
          infinite loop filling up its malloc'd memory.
1501
 
1502
          main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
1503
          not clear_breakpoints_commands, which is now gone.
1504
          (main): If command_loop returns (e.g. from EOF on stdin), do
1505
          a quit_command (looping back to command_loop if quit_command
1506
          doesn't really quit).
1507
          (command_loop): check result from command_line_input and
1508
          exit if it returns NULL, rather than passing the NULL to
1509
          execute_command.
1510
          (gdb_readline):  Free malloc'd result space before returning
1511
          NULL for EOF.
1512
 
1513
        * utils.c (query): Handle C-d to mean "yes", just as if the
1514
          input was not a terminal.  Also avoid infinite loop if EOF
1515
          occurs in mid-input-line before newline.  This allows
1516
          query to be used at EOF on stdin with reasonable results.
1517
 
1518
        * infrun.c (proceed): Set breakpoint_proceeded.
1519
 
1520
        * values.c (value_as_long): Avoid infinite recursion for enums.
1521
          (_initialize_values): Fix typo in help msg (kingdon).
1522
 
1523
        * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
1524
          RL_LIB for linking.  This allows -lreadline for linking
1525
          and nothing for dependencies, once readline is a real library.
1526
 
1527
        * config.gdb: Jim Kingdon: give useful error message if the
1528
          host or target type is not recognized.
1529
 
1530
        * defs.h (alloca): SPARC  does not declare alloca,
1531
          it just defines it.  Dumb, but deal with it.
1532
 
1533
        * Jim Kingdon suggests:
1534
          in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
1535
 
1536
Wed Aug 29 18:03:27 1990  John Gilmore  (gnu at cygint)
1537
 
1538
        * Makefile.dist (VERSION): Bump version # to 3.91.2.
1539
 
1540
        * Clean up Bothner's changes.
1541
 
1542
        * blockframe.c (clear_pc_function_cache): New function.
1543
        * blockframe.c: remake cache_pc_function_* static.
1544
        * dbxread.c (symbol_file_command): remove references to
1545
                    cache_pc_function_* variables.
1546
        * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
1547
        * printcmd.c: Avoid kludging a global variable (addressprint)
1548
          to avoid printing the address of a string twice.  Instead,
1549
          pass the format letter 's' down low enough that it can be seen
1550
          to avoid this problem.
1551
          (print_formatted): Pass format arg to value_print.
1552
          (restore_addressprint): Remove function.
1553
          (do_examine):  Avoid hacking addressprint, cleanups and such.
1554
          (print_frame_args):  Add a comment to a Bothner change.
1555
        * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
1556
        * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
1557
          to wipe out the values cached in blockframe.c.
1558
        * symtab.c (find_method): Add comment saying how big you must
1559
          allocate to be "big enough".  Per being terse again.
1560
        * valprint.c (val_print): Handle format letter "s" to print
1561
          strings without addresses.  Add comment to vtbl printing code
1562
          which casts with wild abandon.  Rearrange reference-printing
1563
          code so it prints:
1564
               @0xaddr: value           (print w/addressprint)
1565
               value                    (print w/~addressprint)
1566
               @0xaddr                  (parameter lists w/addressprint)
1567
          or   nothing                  (parameter lists w/o addressprint)
1568
 
1569
Tue Aug 28 10:47:18 1990  John Gilmore  (gnu at cygint)
1570
 
1571
        * Merge more changes from Per Bothner:
1572
 
1573
Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
1574
annoying) that I tried to improve it. Here are my suggestions.
1575
 
1576
        These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
1577
 
1578
        findvar.c:
1579
        Do automatic de-reference when taking the address of a reference.
1580
        printcmd.c:
1581
        Don't deref_ref when printing parameter lists.
1582
        valops.c:
1583
        More attempts at treating refernences properly.
1584
        valprint.c:
1585
        In val_print, if deref_ref==0, don't print dangling " = ".
1586
        value.h:
1587
        Add COERCE_REF macro, which de-references an REF.
1588
 
1589
        * Merge changes from Per Bothner:
1590
 
1591
* Fixed (Sony news)-specific configuration problems.
1592
* Fixed other problems with using vanilla pcc and libc (enum problems;
1593
assumption that vsprintf exists).
1594
* Some major speed-ups (finc_pc_partial_function now caches a match;
1595
parsing avoids duplicate symbol_lookup calls).
1596
* Changed handling of baseclasses (no longer use baseclasses field
1597
of struct type, use the first n_baseclasses fields instead).
1598
* Various minor changes/fixes, most C++-related.
1599
 
1600
blockframe.c:
1601
Cache the most previous match from find_pc_partial_function.
1602
(Save both low and high ends of matching function's pc range.)
1603
This speeds up the loop of infrun.c:wait_for_inferior quite
1604
a bit, and makes step/next commands much zippier.
1605
command.c:
1606
Added an enum->int cast (otherwise, some compilers barf).
1607
dbxread.c:
1608
No longer set baseclass offset to 0, since multiple
1609
inheritance now mostly works.
1610
Added a number of casts, to shut up compiler warnings
1611
(after stabs where made enums, not ints).
1612
When discarding a symbol table (in symbol_file_command),
1613
must clear the cache introduced in blockframe.c.
1614
Don't convert $vtbl_ptr_type to vtbl any more.
1615
Get rid of TYPE_BASECLASEES and  baseclass_vec (see also symtab.h).
1616
Mask off sign bit emitted by g++ for virtual table offset.
1617
Set voffset to -1 (not 1) for static member functions.
1618
expread.y:
1619
Changed parsing/lexing of names to avoid doing symbol lookup twice
1620
(once when lexing to determine symbol class, once for real).
1621
Now only call symbol_lookup once. Fields of 'this' win especially big.
1622
printcmd.c:
1623
Subpress printing addr twice in the case of 'x/s addr'.
1624
symtab.c:
1625
lookup_basetype_type is no longer used.
1626
Add find_methods as recursive helper function to decode_line_1.
1627
This allows multiple inheritance to work.
1628
Also, once one or more matches has been found, do not look in
1629
base-classes. (Baseclass methods would be overridden, anyway.)
1630
symtab.h:
1631
Removed baseclasses array in struct type.
1632
Instead of using baseclasses[i], use fields[i-1].
1633
Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
1634
Changed sign convention of voffset (previous was inconsistent).
1635
tm-news.h:
1636
Some macros (CALL_DUMMY and relatives) were missing. Put them back.
1637
utils.c:
1638
Used to assume existence of vsprintf. Re-written to not need it
1639
if HAVE_VPRINTF is undefined.
1640
valops.c:
1641
typecmp was too pessimistic. Made it less so.
1642
valprint.c:
1643
Don't print space after address.
1644
If vtable points to a misc symbol (with 0 offset), print it,
1645
since that indicates the actual class of the object.
1646
Changed ype_print_derivation_info to use new inheritance
1647
scheme (without baseclasses vector).
1648
values.c:
1649
In value_primitive_field, fixed some bugs left over from previous set of fixes.
1650
Also, changes needed because TYPE_BASECLASSES were removed.
1651
xm-news.h:
1652
REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.

Tue Aug 21 20:08:54 1990  John Gilmore  (gnu at cygint)
1655
 
1656
        * source.c:
1657
  If there is no path set, and the symbols don't indicate what directory
1658
  a file was compiled in, look in the current directory.  But either
1659
  a path or a known compilation directory will prevent this.
1660
 
1661
        * dbxread.c:
1662
  Three independent bug fixes:
1663
   * Remove the #if 0 block that breaks some stuff.
1664
   * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
1665
     adapt gdb to either SunOS 4.0.* or 4.1.
1666
   * MAX_OF_TYPE and MIN_OF_TYPE thinko.  By tedg@sun, I think.
1667
 
1668
        * symtab.c:
1669
  Instantiate the class T when looking for methods in it.  (Tiemann@sun)
1670
 
1671
        * valprint.c:
1672
  (type_print) Demangle the name being printed.
1673
  (type_print_base) Handle botched demangling without coredump (tiemann).
1674
 
1675
        * values.c:
1676
  (check_stub_method):  Document routine.
1677
                        (tiemann) fix bug for no-arg functions
1678
                        Avoid clobbering beyond end of malloc'd storage.
1679
                        Terminate the argument list properly.
1680

Sat Aug 18 01:29:59 1990  Per Bothner (bothner@cs.wisc.edu)
1682
 
1683
        * Changes merged by John Gilmore:
1684
 
1685
breakpoint.c:
1686
  In breakpoint_1, use new print_address_symbolic instead
1687
  of find_pc_partial_function. (This forces use of assembler-level
1688
  addresses, and avoids misleading non-mangled source-level names.)
1689
cplus-dem.c:
1690
  Generalize ansi argument such that -1 means skip arglist totally.
1691
  Removed global variable print_ansi_qualifiers (which made
1692
  code non-reentrant), in favor of extra explicit arguments
1693
  to internal routines.
1694
printcmd.c:
1695
  Add new helper function print_address_symbolic.
1696
  Use find_pc_misc_function instead of find_pc_partial_function
1697
  (since we want assembler-level symbols here).
1698
stack.c:
1699
  Print unknown function as just "f (...)", not "f (...) (...)".
1700
  Use new fputs_demangled explicitly.
1701
symtab.c:
1702
  Fixed a typing violation (problem: value.h cannot be imported
1703
  without renaming many variable in this file).
1704
  lookup_symbol: If no matching misc_func, look for a C++-mangled name.
1705
  decode_line_1: Moved forward some never-reached code.
1706
  Made decode_line_2 skip function prologues correctly.
1707
utils.c:
1708
  fputs_filtered should not demangle by default.
1709
  Add new fputs_demangled to demangle on demand..
1710
valops.c:
1711
  Change value_struct_elt to use value_primitive_field (using recursive
1712
  utility function search_struct_field). This allows foo.bar to work
1713
  for multiple inheritance (so far only for data fields).
1714
  Change check_field in the same way (recursive helper function
1715
  to support multiple inheritance).
1716
  (Note: there are more of these problems that I haven't fixed.
1717
  Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
1718
  value_of_this: 'this' symbol name is now just "this", note "$this".
1719
valprint.c:
1720
  Don't print static members.
1721
  Avoid printing "members of " if there are none.
1722
  Simplified type_print_derivation_info by merging duplicate code.
1723
  Remove useless blank lines in type_print_base (ptype command).
1724
value.h:
1725
  Added declaration of new routine value_primitive_field.
1726
values.c:
1727
  Added value_primitive_field which is generalized version of
1728
  value_field that can handle multiple inheritance (non-zero offsets etc).
1729
  Re-implemented value_field to call value_primitive_field.
1730
 
1731
Fri Aug 17 23:33:44 1990  John Gilmore  (gnu at cygint)
1732
 
1733
        * infcmd.c -- insert else to avoid 'delete env' coredump when you
1734
        delete the whole environment.  Karl Berry reported the bug.
1735
        * source.c - fix openp to avoid //'s in filenames, which
1736
        trigger an Emacs bug causing it to not be able to find files
1737
        when running gdb in a window.
1738
        * dbxread.c - zap the #if 0 that botches the add-file code.
1739
        It seems to work a lot better without all the code commented out.
1740
 
1741
Fri Jul 20 16:58:46 1990  John Gilmore  (gnu at cygnus.com)
1742
 
1743
        * Merge Tiemann's and Ted Goldstein's changes, detailed below,
1744
        into gdb-3.90.9.
1745
 
1746
Tue Jul 17 19:34:33 1990  Ted Goldstein  (tedg at golem)
1747
 
1748
        * Makefile - added a ${CFLAGS} to a couple of entries,
1749
        added remote-sa.sparc.c
1750
        * added remote.sa-sparc.c, a modification of remote.c
1751
        which conducts a dialog directly with the SparcStation prom.
1752
        * breakpoint.c, infrun.c, sparcdep.c  added
1753
        remote_insert_breakpoint(), and remote_remove_breakpoint()
1754
        to breakpoint.c instead of directly writing breakpoint instructions.
1755
        * sparcdep.c on remote_debugging,there is no need
1756
        to remove signle step breakpoint instructions.
1757
        * main.c added "-epoch" flag and "int epoch_interface" to main.c
1758
        global variable
1759
        * printcmd.c - epoch interface sends lisp expressions to open up
1760
        epoch windows on inspection.
1761
        * valprint.c - added arrayprint, and addressprint and made adding
1762
        format controls easier
1763
        * wait.h added a couple of undef's because we were getting
1764
        complaints about WSTOPSIG and WTERMSIG begin redefined.

1773
 
1774
        * values.c (baseclass_addr): Run loop from INDEX+1 to
1775
        N_BASECLASSES; otherwise, we can still get into a loop.
1776
        @@ This should be restructured to use a cleaner search strategy.
1777
 
1778
Sun Jul  1 12:28:51 1990  Michael Tiemann  (tiemann at masham)
1779

1791
        * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
1792
        should print ANSI qualifiers (such as `const' and `volatile').
1793
        All callers changed to call with ANSI == 1, except from
1794
        `check_method_stub', which uses old-style syntax.
1795
 
1796
        * symseg.h (struct fn_field): Remove unneccessary `args' field.
1797
        * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.

1809
 
1810
        * breakpoint.c (catch_command): New function.  Provides a

1859
        Insert breakpoints and continue (not step) if
1860
        step_resume_break_address != NULL, even if another_trap.
1861
        If trap_expected and we enter sigtramp, then set up a
1862
        step_resume_break.
1863

1864
        set another_trap.
1865

1876
        * infrun.c (wait_for_inferior, after check for trap_expected > 1):
1877
