   1 Wed Jan 12 14:44:45 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
   2
   3         * go32-xdep.c: Remove unused function uerror.
   4         (sigsetmask): Declare return type.  Declare argument (to match the
   5         way it is called).  Explicitly return 0.
   6
   7 Wed Jan 12 01:44:25 1994  John Gilmore  (gnu@cygnus.com)
   8
   9         * symtab.h (struct symbol, general_symbol_info, minimal_symbol,
  10         partial_symbol):  Shrink the storage sizes of symbols, by making
  11         enums into 1-byte bitfields when compiled __GNUC__, moving all the
  12         enums and small ints to the end of each struct to improve
  13         alignment, and switching the section number from int to unsigned
  14         short.
  15
  16 Wed Jan 12 00:16:26 1994  John Gilmore  (gnu@cygnus.com)
  17
  18         * symtab.c (find_addr_symbol):  New routine that will find the nearest
  19         symbol associated with an address.  It does so by exhaustive
  20         search of the symtabs, so it's slow but complete.
  21
  22 Tue Jan 11 23:57:30 1994  John Gilmore  (gnu@cygnus.com)
  23
  24         * coffread.c (read_coff_symtab):  Set PC bounds of _globals_ symtab
  25         to [0,0] rather than [0, end of first source file].  This avoids
  26         problems with other parts of GDB looking for linetables in the
  27         _globals_ symtab.  Eliminate variables num_object_files and
  28         first_object_file_end.
  29
  30 Tue Jan 11 00:53:46 1994  John Gilmore  (gnu@cygnus.com)
  31
  32         * a29k-tdep.c (init_frame_info):  Cast null arg to examine_tag.
  33         (pop_frame):  Restore PC2 and LR0 from dummy frames.
  34         (push_dummy_frame):  Save PC2 and LR0 into dummy frames.
  35         (setup_arbitrary_frame):  Handle 3 args and set up real frames.
  36         * config/a29k/tm-a29k.h (FRAME_NUM_ARGS):  Update comments.
  37         (DUMMY_FRAME_RSIZE):  Add 2 longwords for PC2 and LR0.
  38         (SETUP_ARBITRARY_FRAME):  Define.
  39
  40 Tue Jan 11 06:59:10 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
  41
  42         * infrun.c, config/mips/tm-irix5.h: Remove #if 0'd AT_FUNCTION_START.
  43
  44 Tue Jan 11 14:27:03 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
  45
  46         * remote-udi.c (udi_resume): Correct prototype.
  47
  48 Tue Jan 11 11:10:30 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)
  49
  50         * config/pa/tm-hppa.h (FRAME_FIND_SAVED_REGS): Call
  51         hppa_frame_find_saved_regs.
  52         * hppa-tdep.c (dig_fp_from_stack): Delete function.
  53         (prologue_inst_adjust_sp): New function.
  54         (is_branch, inst_saves_gr, inst_saves_fr): New functions.
  55         (skip_prologue): Completely rewrite to use unwind information.
  56         (hppa_frame_find_saved_regs): Likewise.
  57
  58 Tue Jan 11 06:59:10 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
  59
  60         * remote-mips.c (mips_wait): Use new function mips_signal_from_protocol
  61         to convert a signal number with appropriate bounds checking.
  62
  63         * remote-mips.c (mips_wait): Fix typos (0x177 -> 0177, 0x377 -> 0377).
  64
  65 Tue Jan 11 00:53:46 1994  John Gilmore  (gnu@cygnus.com)
  66
  67         * stack.c (frame_info):  If FRAME_FIND_SAVED_REGS isn't defined,
  68         print a newline to end the display anyway.
  69
  70         * sparc-tdep.c (sparc_pop_frame):  Pop the fsr and csr (float and
  71         coprocessor status regs) when popping a frame.  This fixes
  72         float exceptions that occur after calling inferior functions.
  73
  74         * sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
  75         Read and write the fsr (float status register) to/from the child
  76         process along with the float regs.  Remove Peter Schauer's change
  77         of May 24 '93, which has higher overhead and doesn't solve the
  78         real problem (which was that FSR wasn't being set).
  79
  80 Mon Jan 10 23:16:42 1994  John Gilmore  (gnu@cygnus.com)
  81
  82         * a29k-tdep.c (examine_prologue):  Don't worry if the ASGEQ
  83         stack overflow check isn't right after the register stack
  84         adjustment instruction.  Metaware R2.3u compiler moves other
  85         things in front of it.  This fix isn't perfect but is what's
  86         running.
  87
  88 Mon Jan 10 20:08:23 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
  89
  90         * c-valprint.c (c_val_print): Treat TYPE_CODE_RANGE like TYPE_CODE_INT.
  91
  92         * config/alpha/alpha-netware.mt: Rename to alpha-nw.mt for 14
  93         character filenames.
  94         * configure.in: Change accordingly.
  95
  96 Mon Jan 10 15:48:36 1994  Tom Lord  (lord@rtl.cygnus.com)
  97
  98         * m68k-stub.c, sparc-stub.c: removed spurious introduction of
  99         _filtered io routines from these two files.
 100
 101 Fri Jan  7 12:42:45 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 102
 103         * config/i386/tm-i386v.h, config/m68k/tm-m68k.h, config/mips/tm-mips.h,
 104         config/vax/tm-vax.h (CALL_DUMMY_BREAKPOINT_OFFSET):  Define.
 105         * mdebugread.c (parse_symbol):  Handle enum sh.type produced by
 106         DEC c89.
 107         * mdebugread.c (add_line):  Handle zero linenos produced by DEC c89.
 108
 109 Fri Jan  7 12:55:25 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 110
 111         * utils.c (print_sys_errmsg): Call gdb_flush (gdb_stdout) before
 112         printing to gdb_stderr.
 113
 114         * remote-udi.c (udi_kill): Don't close the connection, just set
 115         inferior_pid to zero.
 116         (udi_mourn): Call remove_breakpoints.
 117
 118         * remote-udi.c: Remove obsolete need_artificial_traps comment.
 119
 120         * i386b-nat.c (sregmap): If sEAX, etc., not defined, use tEAX, etc.
 121
 122 Thu Jan  6 07:17:53 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 123
 124         * symtab.c (lookup_symbol): Don't try adding .c to the name.
 125
 126         * remote-bug.c: At the start of each section, reset srec_frame
 127         back to 160.
 128
 129         * target.h: Add TARGET_WAITKIND_LOADED and TARGET_WAITKIND_SPURIOUS.
 130         * target.c (store_waitstatus): Add CHILD_SPECIAL_WAITSTATUS hook.
 131         * infrun.c (wait_for_inferior): Replace SIGTRAP_STOP_AFTER_LOAD with
 132         code which looks for those two waitkinds.  Use switch statement.
 133         * config/rs6000/tm-rs6000.h: Replace SIGTRAP_STOP_AFTER_LOAD with
 134         CHILD_SPECIAL_WAITSTATUS.
 135
 136         * procfs.c (procfs_wait): Fix argument name to match 4 Jan changes.
 137         * Move target_signal_from_host, target_signal_to_host, and
 138         store_waitstatus from inftarg.c to target.c.  procfs needs them.
 139         * target.c: Include "wait.h" and <signal.h>.
 140         * target.h, infrun.c (proceed), proceed callers: Pass new code
 141         TARGET_SIGNAL_DEFAULT instead of -1.  This avoids problems with
 142         enums being treated as unsigned and is cleaner.
 143         * infrun.c (signals_info): Don't print TARGET_SIGNAL_DEFAULT or
 144         TARGET_SIGNAL_0.
 145         * infcmd.c (signal_command), infrun.c (signals_info):
 146         Don't allow user to specify numeric equivalent of
 147         TARGET_SIGNAL_DEFAULT.
 148
 149 Tue Jan  4 15:34:36 1994  Stu Grossman  (grossman@cygnus.com)
 150
 151         * config/alpha/alpha-netware.mt:  New target support for Alpha
 152         running Netware.
 153         * configure.in:  Add alpha-*-netware* target.
 154
 155 Tue Jan  4 14:51:35 1994  Stan Shebs  (shebs@andros.cygnus.com)
 156
 157         * remote-mips.c (mips_wait): Fix ref to TARGET_WAITKIND_STOPPED.
 158
 159 Tue Jan  4 09:47:14 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 160
 161         * target.h: Add enum target_waitkind, enum target_signal, and
 162         struct target_waitstatus.  Change status argument to target_wait to
 163         be struct target_waitstatus * instead of int *.
 164         * target.h, infrun.c, all targets: Change type of signal arguments
 165         to resume(), proceed(), and target_resume() from int to enum
 166         target_signal.
 167         * All targets (*_wait, *_resume): Change accordingly.
 168         * infcmd.c (program_info, signal_command), throughout infrun.c,
 169         * fork-child.c, solib.c, hppa-tdep.c, osfsolib.c: Use this stuff.
 170         * convex-xdep.c, convex-tdep.c: Add FIXME's (getting the Convex
 171         signal code stuff right with the new signals would be non-trivial).
 172         * inferior.h (stop_signal): Make it enum target_signal not int.
 173         * target.c, target.h (target_signal_to_string, target_signal_to_name,
 174         target_signal_from_name): New functions.
 175         * inftarg.c, target.h (target_signal_to_host, target_signal_from_host,
 176         store_waitstatus): New functions.
 177         * procfs.c (procfs_notice_signals): Use them.
 178         * i960-tdep.c (i960_fault_to_signal): New function, to replace
 179         print_fault.
 180         * config/i960/tm-i960.h: Don't define PRINT_RANDOM_SIGNAL.
 181
 182         * objfiles.c (build_objfile_section_table): Don't abort() if
 183         objfile->sections is already set.
 184
 185         * objfiles.c (add_to_objfile_sections): Check SEC_ALLOC not SEC_LOAD
 186         to match recent change to exec.c.
 187
 188         * Version 4.11.3.
 189
 190         * main.c (print_gdb_version): Change year to 1994.
 191
 192         * ChangeLog, ChangeLog-93: Split ChangeLog at 1994.
 193         * Makefile.in (NONSRC): Add ChangeLog-93.
 194
 195 Mon Jan  3 11:57:29 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 196
 197         * stabsread.c (read_type): Allow defining several type numbers
 198         at once (e.g. "(1,2)=(3,4)="...).
 199
 200         * stabsread.c (read_enum_type): Use TARGET_INT_BIT not sizeof (int).
 201
 202         * breakpoint.c (frame_in_dummy): Check PC as well as frame.
 203
 204 Mon Jan  3 02:47:03 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 205
 206         * mdebugread.c (psymtab_to_symtab_1):  Only pass N_STAB symbols
 207         to process_one_symbol.
 208         * symtab.c (find_pc_psymbol):  Search global_psymbols as well to
 209         avoid caching a bad endaddr in find_pc_partial_function.
 210
 211 Sun Jan  2 21:41:17 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 212
 213         * config/m68k/tm-sun3.h: Don't define BELIEVE_PCC_PROMOTION.
 214
 215 Sat Jan  1 04:35:23 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 216
 217         * infrun.c (wait_for_inferior):  Do not step or step resume past
 218         the end of a one-line function we just stepped into.
