   1 Wed Jan 12 01:44:25 1994  John Gilmore  (gnu@cygnus.com)
   2
   3         * symtab.h (struct symbol, general_symbol_info, minimal_symbol,
   4         partial_symbol):  Shrink the storage sizes of symbols, by making
   5         enums into 1-byte bitfields when compiled __GNUC__, moving all the
   6         enums and small ints to the end of each struct to improve
   7         alignment, and switching the section number from int to unsigned
   8         short.
   9
  10 Wed Jan 12 00:16:26 1994  John Gilmore  (gnu@cygnus.com)
  11
  12         * symtab.c (find_addr_symbol):  New routine that will find the nearest
  13         symbol associated with an address.  It does so by exhaustive
  14         search of the symtabs, so it's slow but complete.
  15
  16 Tue Jan 11 23:57:30 1994  John Gilmore  (gnu@cygnus.com)
  17
  18         * coffread.c (read_coff_symtab):  Set PC bounds of _globals_ symtab
  19         to [0,0] rather than [0, end of first source file].  This avoids
  20         problems with other parts of GDB looking for linetables in the
  21         _globals_ symtab.  Eliminate variables num_object_files and
  22         first_object_file_end.
  23
  24 Tue Jan 11 00:53:46 1994  John Gilmore  (gnu@cygnus.com)
  25
  26         * a29k-tdep.c (init_frame_info):  Cast null arg to examine_tag.
  27         (pop_frame):  Restore PC2 and LR0 from dummy frames.
  28         (push_dummy_frame):  Save PC2 and LR0 into dummy frames.
  29         (setup_arbitrary_frame):  Handle 3 args and set up real frames.
  30         * config/a29k/tm-a29k.h (FRAME_NUM_ARGS):  Update comments.
  31         (DUMMY_FRAME_RSIZE):  Add 2 longwords for PC2 and LR0.
  32         (SETUP_ARBITRARY_FRAME):  Define.
  33
  34 Tue Jan 11 06:59:10 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
  35
  36         * infrun.c, config/mips/tm-irix5.h: Remove #if 0'd AT_FUNCTION_START.
  37
  38 Tue Jan 11 14:27:03 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
  39
  40         * remote-udi.c (udi_resume): Correct prototype.
  41
  42 Tue Jan 11 11:10:30 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)
  43
  44         * config/pa/tm-hppa.h (FRAME_FIND_SAVED_REGS): Call
  45         hppa_frame_find_saved_regs.
  46         * hppa-tdep.c (dig_fp_from_stack): Delete function.
  47         (prologue_inst_adjust_sp): New function.
  48         (is_branch, inst_saves_gr, inst_saves_fr): New functions.
  49         (skip_prologue): Completely rewrite to use unwind information.
  50         (hppa_frame_find_saved_regs): Likewise.
  51
  52 Tue Jan 11 06:59:10 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
  53
  54         * remote-mips.c (mips_wait): Use new function mips_signal_from_protocol
  55         to convert a signal number with appropriate bounds checking.
  56
  57         * remote-mips.c (mips_wait): Fix typos (0x177 -> 0177, 0x377 -> 0377).
  58
  59 Tue Jan 11 00:53:46 1994  John Gilmore  (gnu@cygnus.com)
  60
  61         * stack.c (frame_info):  If FRAME_FIND_SAVED_REGS isn't defined,
  62         print a newline to end the display anyway.
  63
  64         * sparc-tdep.c (sparc_pop_frame):  Pop the fsr and csr (float and
  65         coprocessor status regs) when popping a frame.  This fixes
  66         float exceptions that occur after calling inferior functions.
  67
  68         * sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
  69         Read and write the fsr (float status register) to/from the child
  70         process along with the float regs.  Remove Peter Schauer's change
  71         of May 24 '93, which has higher overhead and doesn't solve the
  72         real problem (which was that FSR wasn't being set).
  73
  74 Mon Jan 10 23:16:42 1994  John Gilmore  (gnu@cygnus.com)
  75
  76         * a29k-tdep.c (examine_prologue):  Don't worry if the ASGEQ
  77         stack overflow check isn't right after the register stack
  78         adjustment instruction.  Metaware R2.3u compiler moves other
  79         things in front of it.  This fix isn't perfect but is what's
  80         running.
  81
  82 Mon Jan 10 20:08:23 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
  83
  84         * c-valprint.c (c_val_print): Treat TYPE_CODE_RANGE like TYPE_CODE_INT.
  85
  86         * config/alpha/alpha-netware.mt: Rename to alpha-nw.mt for 14
  87         character filenames.
  88         * configure.in: Change accordingly.
  89
  90 Mon Jan 10 15:48:36 1994  Tom Lord  (lord@rtl.cygnus.com)
  91
  92         * m68k-stub.c, sparc-stub.c: removed spurious introduction of
  93         _filtered io routines from these two files.
  94
  95 Fri Jan  7 12:42:45 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
  96
  97         * config/i386/tm-i386v.h, config/m68k/tm-m68k.h, config/mips/tm-mips.h,
  98         config/vax/tm-vax.h (CALL_DUMMY_BREAKPOINT_OFFSET):  Define.
  99         * mdebugread.c (parse_symbol):  Handle enum sh.type produced by
 100         DEC c89.
 101         * mdebugread.c (add_line):  Handle zero linenos produced by DEC c89.
 102
 103 Fri Jan  7 12:55:25 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 104
 105         * utils.c (print_sys_errmsg): Call gdb_flush (gdb_stdout) before
 106         printing to gdb_stderr.
 107
 108         * remote-udi.c (udi_kill): Don't close the connection, just set
 109         inferior_pid to zero.
 110         (udi_mourn): Call remove_breakpoints.
 111
 112         * remote-udi.c: Remove obsolete need_artificial_traps comment.
 113
 114         * i386b-nat.c (sregmap): If sEAX, etc., not defined, use tEAX, etc.
 115
 116 Thu Jan  6 07:17:53 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 117
 118         * symtab.c (lookup_symbol): Don't try adding .c to the name.
 119
 120         * remote-bug.c: At the start of each section, reset srec_frame
 121         back to 160.
 122
 123         * target.h: Add TARGET_WAITKIND_LOADED and TARGET_WAITKIND_SPURIOUS.
 124         * target.c (store_waitstatus): Add CHILD_SPECIAL_WAITSTATUS hook.
 125         * infrun.c (wait_for_inferior): Replace SIGTRAP_STOP_AFTER_LOAD with
 126         code which looks for those two waitkinds.  Use switch statement.
 127         * config/rs6000/tm-rs6000.h: Replace SIGTRAP_STOP_AFTER_LOAD with
 128         CHILD_SPECIAL_WAITSTATUS.
 129
 130         * procfs.c (procfs_wait): Fix argument name to match 4 Jan changes.
 131         * Move target_signal_from_host, target_signal_to_host, and
 132         store_waitstatus from inftarg.c to target.c.  procfs needs them.
 133         * target.c: Include "wait.h" and <signal.h>.
 134         * target.h, infrun.c (proceed), proceed callers: Pass new code
 135         TARGET_SIGNAL_DEFAULT instead of -1.  This avoids problems with
 136         enums being treated as unsigned and is cleaner.
 137         * infrun.c (signals_info): Don't print TARGET_SIGNAL_DEFAULT or
 138         TARGET_SIGNAL_0.
 139         * infcmd.c (signal_command), infrun.c (signals_info):
 140         Don't allow user to specify numeric equivalent of
 141         TARGET_SIGNAL_DEFAULT.
 142
 143 Tue Jan  4 15:34:36 1994  Stu Grossman  (grossman@cygnus.com)
 144
 145         * config/alpha/alpha-netware.mt:  New target support for Alpha
 146         running Netware.
 147         * configure.in:  Add alpha-*-netware* target.
 148
 149 Tue Jan  4 14:51:35 1994  Stan Shebs  (shebs@andros.cygnus.com)
 150
 151         * remote-mips.c (mips_wait): Fix ref to TARGET_WAITKIND_STOPPED.
 152
 153 Tue Jan  4 09:47:14 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 154
 155         * target.h: Add enum target_waitkind, enum target_signal, and
 156         struct target_waitstatus.  Change status argument to target_wait to
 157         be struct target_waitstatus * instead of int *.
 158         * target.h, infrun.c, all targets: Change type of signal arguments
 159         to resume(), proceed(), and target_resume() from int to enum
 160         target_signal.
 161         * All targets (*_wait, *_resume): Change accordingly.
 162         * infcmd.c (program_info, signal_command), throughout infrun.c,
 163         * fork-child.c, solib.c, hppa-tdep.c, osfsolib.c: Use this stuff.
 164         * convex-xdep.c, convex-tdep.c: Add FIXME's (getting the Convex
 165         signal code stuff right with the new signals would be non-trivial).
 166         * inferior.h (stop_signal): Make it enum target_signal not int.
 167         * target.c, target.h (target_signal_to_string, target_signal_to_name,
 168         target_signal_from_name): New functions.
 169         * inftarg.c, target.h (target_signal_to_host, target_signal_from_host,
 170         store_waitstatus): New functions.
 171         * procfs.c (procfs_notice_signals): Use them.
 172         * i960-tdep.c (i960_fault_to_signal): New function, to replace
 173         print_fault.
 174         * config/i960/tm-i960.h: Don't define PRINT_RANDOM_SIGNAL.
 175
 176         * objfiles.c (build_objfile_section_table): Don't abort() if
 177         objfile->sections is already set.
 178
 179         * objfiles.c (add_to_objfile_sections): Check SEC_ALLOC not SEC_LOAD
 180         to match recent change to exec.c.
 181
 182         * Version 4.11.3.
 183
 184         * main.c (print_gdb_version): Change year to 1994.
 185
 186         * ChangeLog, ChangeLog-93: Split ChangeLog at 1994.
 187         * Makefile.in (NONSRC): Add ChangeLog-93.
 188
 189 Mon Jan  3 11:57:29 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 190
 191         * stabsread.c (read_type): Allow defining several type numbers
 192         at once (e.g. "(1,2)=(3,4)="...).
 193
 194         * stabsread.c (read_enum_type): Use TARGET_INT_BIT not sizeof (int).
 195
 196         * breakpoint.c (frame_in_dummy): Check PC as well as frame.
 197
 198 Mon Jan  3 02:47:03 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 199
 200         * mdebugread.c (psymtab_to_symtab_1):  Only pass N_STAB symbols
 201         to process_one_symbol.
 202         * symtab.c (find_pc_psymbol):  Search global_psymbols as well to
 203         avoid caching a bad endaddr in find_pc_partial_function.
 204
 205 Sun Jan  2 21:41:17 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 206
 207         * config/m68k/tm-sun3.h: Don't define BELIEVE_PCC_PROMOTION.
 208
 209 Sat Jan  1 04:35:23 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 210
 211         * infrun.c (wait_for_inferior):  Do not step or step resume past
 212         the end of a one-line function we just stepped into.
