   1 Thu Jan 13 10:32:38 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
   2
   3         * printcmd.c (print_address_symbolic): If set print fast-symbolic-addr
   4         is on, call find_pc_function rather than relying just on the minimal
   5         symbols (probably only matters for symbol readers which don't put
   6         statics in the minimal symbols, but changing this strikes me as
   7         not conservative enough).
   8         Initialize name_location in all cases.
   9         If no symbol and no msymbol, don't print anything symbolic.
  10
  11         * a29k-tdep.c (push_dummy_frame): Add comment about saving lr0.
  12
  13 Wed Jan 12 20:53:16 1994  John Gilmore  (gnu@cygnus.com)
  14
  15         * printcmd.c (print_address_symbolic):  Make it search the
  16         symtabs for variables as well as functions.  Add `set print
  17         fast-symbolic-addr' and default it to fast (the old way).
  18         Print line numbers for data items as well as functions.
  19
  20         * symtab.c (find_addr_symbol):  Return the symtab and the symbol
  21         address, if a symbol is found (take two more args pointing to
  22         where to store these results).
  23
  24         * symtab.h (find_addr_symbol):  Add prototype.
  25
  26 Wed Jan 12 19:32:11 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
  27
  28         * objfiles.h: Fix comments to reflect the fact that the phrase
  29         "top of stack" always refers to where the pushing and popping takes
  30         place, regardless of whether it is at the highest or lowest address.
  31
  32 Wed Jan 12 13:23:37 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
  33
  34         * mdebugread.c (parse_symbol):  Do not set TYPE_TAG_NAME for
  35         compiler generated tag names.
  36         * mdebugread.c (parse_type):  Handle cross references to qualified
  37         aggregate types.
  38         * valops.c (value_struct_elt):  Improve error message if the
  39         address of a method is requested from an object instance.
  40         * valops.c (search_struct_method):  Make name_matched non-static
  41         to get it initialized correctly.
  42         * config/i386/nm-i386sco.h (CANNOT_STORE_REGISTER):  Define to
  43         exclude segment register which are not writable on newer SCO versions.
  44
  45 Wed Jan 12 14:44:45 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
  46
  47         * go32-xdep.c: Remove unused function uerror.
  48         (sigsetmask): Declare return type.  Declare argument (to match the
  49         way it is called).  Explicitly return 0.
  50
  51 Wed Jan 12 01:44:25 1994  John Gilmore  (gnu@cygnus.com)
  52
  53         * symtab.h (struct symbol, general_symbol_info, minimal_symbol,
  54         partial_symbol):  Shrink the storage sizes of symbols, by making
  55         enums into 1-byte bitfields when compiled __GNUC__, moving all the
  56         enums and small ints to the end of each struct to improve
  57         alignment, and switching the section number from int to unsigned
  58         short.
  59
  60 Wed Jan 12 00:16:26 1994  John Gilmore  (gnu@cygnus.com)
  61
  62         * symtab.c (find_addr_symbol):  New routine that will find the nearest
  63         symbol associated with an address.  It does so by exhaustive
  64         search of the symtabs, so it's slow but complete.
  65
  66 Tue Jan 11 23:57:30 1994  John Gilmore  (gnu@cygnus.com)
  67
  68         * coffread.c (read_coff_symtab):  Set PC bounds of _globals_ symtab
  69         to [0,0] rather than [0, end of first source file].  This avoids
  70         problems with other parts of GDB looking for linetables in the
  71         _globals_ symtab.  Eliminate variables num_object_files and
  72         first_object_file_end.
  73
  74 Tue Jan 11 00:53:46 1994  John Gilmore  (gnu@cygnus.com)
  75
  76         * a29k-tdep.c (init_frame_info):  Cast null arg to examine_tag.
  77         (pop_frame):  Restore PC2 and LR0 from dummy frames.
  78         (push_dummy_frame):  Save PC2 and LR0 into dummy frames.
  79         (setup_arbitrary_frame):  Handle 3 args and set up real frames.
  80         * config/a29k/tm-a29k.h (FRAME_NUM_ARGS):  Update comments.
  81         (DUMMY_FRAME_RSIZE):  Add 2 longwords for PC2 and LR0.
  82         (SETUP_ARBITRARY_FRAME):  Define.
  83
  84 Tue Jan 11 06:59:10 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
  85
  86         * infrun.c, config/mips/tm-irix5.h: Remove #if 0'd AT_FUNCTION_START.
  87
  88 Tue Jan 11 14:27:03 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
  89
  90         * remote-udi.c (udi_resume): Correct prototype.
  91
  92 Tue Jan 11 11:10:30 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)
  93
  94         * config/pa/tm-hppa.h (FRAME_FIND_SAVED_REGS): Call
  95         hppa_frame_find_saved_regs.
  96         * hppa-tdep.c (dig_fp_from_stack): Delete function.
  97         (prologue_inst_adjust_sp): New function.
  98         (is_branch, inst_saves_gr, inst_saves_fr): New functions.
  99         (skip_prologue): Completely rewrite to use unwind information.
 100         (hppa_frame_find_saved_regs): Likewise.
 101
 102 Tue Jan 11 06:59:10 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 103
 104         * remote-mips.c (mips_wait): Use new function mips_signal_from_protocol
 105         to convert a signal number with appropriate bounds checking.
 106
 107         * remote-mips.c (mips_wait): Fix typos (0x177 -> 0177, 0x377 -> 0377).
 108
 109 Tue Jan 11 00:53:46 1994  John Gilmore  (gnu@cygnus.com)
 110
 111         * stack.c (frame_info):  If FRAME_FIND_SAVED_REGS isn't defined,
 112         print a newline to end the display anyway.
 113
 114         * sparc-tdep.c (sparc_pop_frame):  Pop the fsr and csr (float and
 115         coprocessor status regs) when popping a frame.  This fixes
 116         float exceptions that occur after calling inferior functions.
 117
 118         * sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
 119         Read and write the fsr (float status register) to/from the child
 120         process along with the float regs.  Remove Peter Schauer's change
 121         of May 24 '93, which has higher overhead and doesn't solve the
 122         real problem (which was that FSR wasn't being set).
 123
 124 Mon Jan 10 23:16:42 1994  John Gilmore  (gnu@cygnus.com)
 125
 126         * a29k-tdep.c (examine_prologue):  Don't worry if the ASGEQ
 127         stack overflow check isn't right after the register stack
 128         adjustment instruction.  Metaware R2.3u compiler moves other
 129         things in front of it.  This fix isn't perfect but is what's
 130         running.
 131
 132 Mon Jan 10 20:08:23 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 133
 134         * c-valprint.c (c_val_print): Treat TYPE_CODE_RANGE like TYPE_CODE_INT.
 135
 136         * config/alpha/alpha-netware.mt: Rename to alpha-nw.mt for 14
 137         character filenames.
 138         * configure.in: Change accordingly.
 139
 140 Mon Jan 10 15:48:36 1994  Tom Lord  (lord@rtl.cygnus.com)
 141
 142         * m68k-stub.c, sparc-stub.c: removed spurious introduction of
 143         _filtered io routines from these two files.
 144
 145 Fri Jan  7 12:42:45 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 146
 147         * config/i386/tm-i386v.h, config/m68k/tm-m68k.h, config/mips/tm-mips.h,
 148         config/vax/tm-vax.h (CALL_DUMMY_BREAKPOINT_OFFSET):  Define.
 149         * mdebugread.c (parse_symbol):  Handle enum sh.type produced by
 150         DEC c89.
 151         * mdebugread.c (add_line):  Handle zero linenos produced by DEC c89.
 152
 153 Fri Jan  7 12:55:25 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 154
 155         * utils.c (print_sys_errmsg): Call gdb_flush (gdb_stdout) before
 156         printing to gdb_stderr.
 157
 158         * remote-udi.c (udi_kill): Don't close the connection, just set
 159         inferior_pid to zero.
 160         (udi_mourn): Call remove_breakpoints.
 161
 162         * remote-udi.c: Remove obsolete need_artificial_traps comment.
 163
 164         * i386b-nat.c (sregmap): If sEAX, etc., not defined, use tEAX, etc.
 165
 166 Thu Jan  6 07:17:53 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 167
 168         * symtab.c (lookup_symbol): Don't try adding .c to the name.
 169
 170         * remote-bug.c: At the start of each section, reset srec_frame
 171         back to 160.
 172
 173         * target.h: Add TARGET_WAITKIND_LOADED and TARGET_WAITKIND_SPURIOUS.
 174         * target.c (store_waitstatus): Add CHILD_SPECIAL_WAITSTATUS hook.
 175         * infrun.c (wait_for_inferior): Replace SIGTRAP_STOP_AFTER_LOAD with
 176         code which looks for those two waitkinds.  Use switch statement.
 177         * config/rs6000/tm-rs6000.h: Replace SIGTRAP_STOP_AFTER_LOAD with
 178         CHILD_SPECIAL_WAITSTATUS.
 179
 180         * procfs.c (procfs_wait): Fix argument name to match 4 Jan changes.
 181         * Move target_signal_from_host, target_signal_to_host, and
 182         store_waitstatus from inftarg.c to target.c.  procfs needs them.
 183         * target.c: Include "wait.h" and <signal.h>.
 184         * target.h, infrun.c (proceed), proceed callers: Pass new code
 185         TARGET_SIGNAL_DEFAULT instead of -1.  This avoids problems with
 186         enums being treated as unsigned and is cleaner.
 187         * infrun.c (signals_info): Don't print TARGET_SIGNAL_DEFAULT or
 188         TARGET_SIGNAL_0.
 189         * infcmd.c (signal_command), infrun.c (signals_info):
 190         Don't allow user to specify numeric equivalent of
 191         TARGET_SIGNAL_DEFAULT.
 192
 193 Tue Jan  4 15:34:36 1994  Stu Grossman  (grossman@cygnus.com)
 194
 195         * config/alpha/alpha-netware.mt:  New target support for Alpha
 196         running Netware.
 197         * configure.in:  Add alpha-*-netware* target.
 198
 199 Tue Jan  4 14:51:35 1994  Stan Shebs  (shebs@andros.cygnus.com)
 200
 201         * remote-mips.c (mips_wait): Fix ref to TARGET_WAITKIND_STOPPED.
 202
 203 Tue Jan  4 09:47:14 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 204
 205         * target.h: Add enum target_waitkind, enum target_signal, and
 206         struct target_waitstatus.  Change status argument to target_wait to
 207         be struct target_waitstatus * instead of int *.
 208         * target.h, infrun.c, all targets: Change type of signal arguments
 209         to resume(), proceed(), and target_resume() from int to enum
 210         target_signal.
 211         * All targets (*_wait, *_resume): Change accordingly.
 212         * infcmd.c (program_info, signal_command), throughout infrun.c,
 213         * fork-child.c, solib.c, hppa-tdep.c, osfsolib.c: Use this stuff.
 214         * convex-xdep.c, convex-tdep.c: Add FIXME's (getting the Convex
 215         signal code stuff right with the new signals would be non-trivial).
 216         * inferior.h (stop_signal): Make it enum target_signal not int.
 217         * target.c, target.h (target_signal_to_string, target_signal_to_name,
 218         target_signal_from_name): New functions.
 219         * inftarg.c, target.h (target_signal_to_host, target_signal_from_host,
 220         store_waitstatus): New functions.
 221         * procfs.c (procfs_notice_signals): Use them.
 222         * i960-tdep.c (i960_fault_to_signal): New function, to replace
 223         print_fault.
 224         * config/i960/tm-i960.h: Don't define PRINT_RANDOM_SIGNAL.
 225
 226         * objfiles.c (build_objfile_section_table): Don't abort() if
 227         objfile->sections is already set.
 228
 229         * objfiles.c (add_to_objfile_sections): Check SEC_ALLOC not SEC_LOAD
 230         to match recent change to exec.c.
 231
 232         * Version 4.11.3.
 233
 234         * main.c (print_gdb_version): Change year to 1994.
 235
 236         * ChangeLog, ChangeLog-93: Split ChangeLog at 1994.
 237         * Makefile.in (NONSRC): Add ChangeLog-93.
 238
 239 Mon Jan  3 11:57:29 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 240
 241         * stabsread.c (read_type): Allow defining several type numbers
 242         at once (e.g. "(1,2)=(3,4)="...).
 243
 244         * stabsread.c (read_enum_type): Use TARGET_INT_BIT not sizeof (int).
 245
 246         * breakpoint.c (frame_in_dummy): Check PC as well as frame.
 247
 248 Mon Jan  3 02:47:03 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 249
 250         * mdebugread.c (psymtab_to_symtab_1):  Only pass N_STAB symbols
 251         to process_one_symbol.
 252         * symtab.c (find_pc_psymbol):  Search global_psymbols as well to
 253         avoid caching a bad endaddr in find_pc_partial_function.
 254
 255 Sun Jan  2 21:41:17 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 256
 257         * config/m68k/tm-sun3.h: Don't define BELIEVE_PCC_PROMOTION.
 258
 259 Sat Jan  1 04:35:23 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 260
 261         * infrun.c (wait_for_inferior):  Do not step or step resume past
 262         the end of a one-line function we just stepped into.
