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

 235
 236         * infrun.c (wait_for_inferior):  Do not step or step resume past
 237         the end of a one-line function we just stepped into.
