   1 Thu Jan 13 10:32:38 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
   2
   3         Add search to target vector (#if 0'd until after 4.12):
   4         * target.h (to_search, target_search): Add.
   5         * gdbcore.h, core.c (generic_search): Add.
   6         * remote.c (remote_search): Add.
   7         * a29k-tdep.c (init_frame_info): Use target_search to find traceback
   8         tag.
   9
  10         * printcmd.c (print_address_symbolic): If set print fast-symbolic-addr
  11         is on, call find_pc_function rather than relying just on the minimal
  12         symbols (probably only matters for symbol readers which don't put
  13         statics in the minimal symbols, but changing this strikes me as
  14         not conservative enough).
  15         Initialize name_location in all cases.
  16         If no symbol and no msymbol, don't print anything symbolic.
  17
  18         * a29k-tdep.c (push_dummy_frame): Add comment about saving lr0.
  19
  20 Wed Jan 12 20:53:16 1994  John Gilmore  (gnu@cygnus.com)
  21
  22         * printcmd.c (print_address_symbolic):  Make it search the
  23         symtabs for variables as well as functions.  Add `set print
  24         fast-symbolic-addr' and default it to fast (the old way).
  25         Print line numbers for data items as well as functions.
  26
  27         * symtab.c (find_addr_symbol):  Return the symtab and the symbol
  28         address, if a symbol is found (take two more args pointing to
  29         where to store these results).
  30
  31         * symtab.h (find_addr_symbol):  Add prototype.
  32
  33 Wed Jan 12 19:32:11 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
  34
  35         * objfiles.h: Fix comments to reflect the fact that the phrase
  36         "top of stack" always refers to where the pushing and popping takes
  37         place, regardless of whether it is at the highest or lowest address.
  38
  39 Wed Jan 12 13:23:37 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
  40
  41         * mdebugread.c (parse_symbol):  Do not set TYPE_TAG_NAME for
  42         compiler generated tag names.
  43         * mdebugread.c (parse_type):  Handle cross references to qualified
  44         aggregate types.
  45         * valops.c (value_struct_elt):  Improve error message if the
  46         address of a method is requested from an object instance.
  47         * valops.c (search_struct_method):  Make name_matched non-static
  48         to get it initialized correctly.
  49         * config/i386/nm-i386sco.h (CANNOT_STORE_REGISTER):  Define to
  50         exclude segment register which are not writable on newer SCO versions.
  51
  52 Wed Jan 12 14:44:45 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
  53
  54         * go32-xdep.c: Remove unused function uerror.
  55         (sigsetmask): Declare return type.  Declare argument (to match the
  56         way it is called).  Explicitly return 0.
  57
  58 Wed Jan 12 01:44:25 1994  John Gilmore  (gnu@cygnus.com)
  59
  60         * symtab.h (struct symbol, general_symbol_info, minimal_symbol,
  61         partial_symbol):  Shrink the storage sizes of symbols, by making
  62         enums into 1-byte bitfields when compiled __GNUC__, moving all the
  63         enums and small ints to the end of each struct to improve
  64         alignment, and switching the section number from int to unsigned
  65         short.
  66
  67 Wed Jan 12 00:16:26 1994  John Gilmore  (gnu@cygnus.com)
  68
  69         * symtab.c (find_addr_symbol):  New routine that will find the nearest
  70         symbol associated with an address.  It does so by exhaustive
  71         search of the symtabs, so it's slow but complete.
  72
  73 Tue Jan 11 23:57:30 1994  John Gilmore  (gnu@cygnus.com)
  74
  75         * coffread.c (read_coff_symtab):  Set PC bounds of _globals_ symtab
  76         to [0,0] rather than [0, end of first source file].  This avoids
  77         problems with other parts of GDB looking for linetables in the
  78         _globals_ symtab.  Eliminate variables num_object_files and
  79         first_object_file_end.
  80
  81 Tue Jan 11 00:53:46 1994  John Gilmore  (gnu@cygnus.com)
  82
  83         * a29k-tdep.c (init_frame_info):  Cast null arg to examine_tag.
  84         (pop_frame):  Restore PC2 and LR0 from dummy frames.
  85         (push_dummy_frame):  Save PC2 and LR0 into dummy frames.
  86         (setup_arbitrary_frame):  Handle 3 args and set up real frames.
  87         * config/a29k/tm-a29k.h (FRAME_NUM_ARGS):  Update comments.
  88         (DUMMY_FRAME_RSIZE):  Add 2 longwords for PC2 and LR0.
  89         (SETUP_ARBITRARY_FRAME):  Define.
  90
  91 Tue Jan 11 06:59:10 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
  92
  93         * infrun.c, config/mips/tm-irix5.h: Remove #if 0'd AT_FUNCTION_START.
  94
  95 Tue Jan 11 14:27:03 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
  96
  97         * remote-udi.c (udi_resume): Correct prototype.
  98
  99 Tue Jan 11 11:10:30 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)
 100
 101         * config/pa/tm-hppa.h (FRAME_FIND_SAVED_REGS): Call
 102         hppa_frame_find_saved_regs.
 103         * hppa-tdep.c (dig_fp_from_stack): Delete function.
 104         (prologue_inst_adjust_sp): New function.
 105         (is_branch, inst_saves_gr, inst_saves_fr): New functions.
 106         (skip_prologue): Completely rewrite to use unwind information.
 107         (hppa_frame_find_saved_regs): Likewise.
 108
 109 Tue Jan 11 06:59:10 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 110
 111         * remote-mips.c (mips_wait): Use new function mips_signal_from_protocol
 112         to convert a signal number with appropriate bounds checking.
 113
 114         * remote-mips.c (mips_wait): Fix typos (0x177 -> 0177, 0x377 -> 0377).
 115
 116 Tue Jan 11 00:53:46 1994  John Gilmore  (gnu@cygnus.com)
 117
 118         * stack.c (frame_info):  If FRAME_FIND_SAVED_REGS isn't defined,
 119         print a newline to end the display anyway.
 120
 121         * sparc-tdep.c (sparc_pop_frame):  Pop the fsr and csr (float and
 122         coprocessor status regs) when popping a frame.  This fixes
 123         float exceptions that occur after calling inferior functions.
 124
 125         * sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
 126         Read and write the fsr (float status register) to/from the child
 127         process along with the float regs.  Remove Peter Schauer's change
 128         of May 24 '93, which has higher overhead and doesn't solve the
 129         real problem (which was that FSR wasn't being set).
 130
 131 Mon Jan 10 23:16:42 1994  John Gilmore  (gnu@cygnus.com)
 132
 133         * a29k-tdep.c (examine_prologue):  Don't worry if the ASGEQ
 134         stack overflow check isn't right after the register stack
 135         adjustment instruction.  Metaware R2.3u compiler moves other
 136         things in front of it.  This fix isn't perfect but is what's
 137         running.
 138
 139 Mon Jan 10 20:08:23 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 140
 141         * c-valprint.c (c_val_print): Treat TYPE_CODE_RANGE like TYPE_CODE_INT.
 142
 143         * config/alpha/alpha-netware.mt: Rename to alpha-nw.mt for 14
 144         character filenames.
 145         * configure.in: Change accordingly.
 146
 147 Mon Jan 10 15:48:36 1994  Tom Lord  (lord@rtl.cygnus.com)
 148
 149         * m68k-stub.c, sparc-stub.c: removed spurious introduction of
 150         _filtered io routines from these two files.
 151
 152 Fri Jan  7 12:42:45 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 153
 154         * config/i386/tm-i386v.h, config/m68k/tm-m68k.h, config/mips/tm-mips.h,
 155         config/vax/tm-vax.h (CALL_DUMMY_BREAKPOINT_OFFSET):  Define.
 156         * mdebugread.c (parse_symbol):  Handle enum sh.type produced by
 157         DEC c89.
 158         * mdebugread.c (add_line):  Handle zero linenos produced by DEC c89.
 159
 160 Fri Jan  7 12:55:25 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 161
 162         * utils.c (print_sys_errmsg): Call gdb_flush (gdb_stdout) before
 163         printing to gdb_stderr.
 164
 165         * remote-udi.c (udi_kill): Don't close the connection, just set
 166         inferior_pid to zero.
 167         (udi_mourn): Call remove_breakpoints.
 168
 169         * remote-udi.c: Remove obsolete need_artificial_traps comment.
 170
 171         * i386b-nat.c (sregmap): If sEAX, etc., not defined, use tEAX, etc.
 172
 173 Thu Jan  6 07:17:53 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 174
 175         * symtab.c (lookup_symbol): Don't try adding .c to the name.
 176
 177         * remote-bug.c: At the start of each section, reset srec_frame
 178         back to 160.
 179
 180         * target.h: Add TARGET_WAITKIND_LOADED and TARGET_WAITKIND_SPURIOUS.
 181         * target.c (store_waitstatus): Add CHILD_SPECIAL_WAITSTATUS hook.
 182         * infrun.c (wait_for_inferior): Replace SIGTRAP_STOP_AFTER_LOAD with
 183         code which looks for those two waitkinds.  Use switch statement.
 184         * config/rs6000/tm-rs6000.h: Replace SIGTRAP_STOP_AFTER_LOAD with
 185         CHILD_SPECIAL_WAITSTATUS.
 186
 187         * procfs.c (procfs_wait): Fix argument name to match 4 Jan changes.
 188         * Move target_signal_from_host, target_signal_to_host, and
 189         store_waitstatus from inftarg.c to target.c.  procfs needs them.
 190         * target.c: Include "wait.h" and <signal.h>.
 191         * target.h, infrun.c (proceed), proceed callers: Pass new code
 192         TARGET_SIGNAL_DEFAULT instead of -1.  This avoids problems with
 193         enums being treated as unsigned and is cleaner.
 194         * infrun.c (signals_info): Don't print TARGET_SIGNAL_DEFAULT or
 195         TARGET_SIGNAL_0.
 196         * infcmd.c (signal_command), infrun.c (signals_info):
 197         Don't allow user to specify numeric equivalent of
 198         TARGET_SIGNAL_DEFAULT.
 199
 200 Tue Jan  4 15:34:36 1994  Stu Grossman  (grossman@cygnus.com)
 201
 202         * config/alpha/alpha-netware.mt:  New target support for Alpha
 203         running Netware.
 204         * configure.in:  Add alpha-*-netware* target.
 205
 206 Tue Jan  4 14:51:35 1994  Stan Shebs  (shebs@andros.cygnus.com)
 207
 208         * remote-mips.c (mips_wait): Fix ref to TARGET_WAITKIND_STOPPED.
 209
 210 Tue Jan  4 09:47:14 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 211
 212         * target.h: Add enum target_waitkind, enum target_signal, and
 213         struct target_waitstatus.  Change status argument to target_wait to
 214         be struct target_waitstatus * instead of int *.
 215         * target.h, infrun.c, all targets: Change type of signal arguments
 216         to resume(), proceed(), and target_resume() from int to enum
 217         target_signal.
 218         * All targets (*_wait, *_resume): Change accordingly.
 219         * infcmd.c (program_info, signal_command), throughout infrun.c,
 220         * fork-child.c, solib.c, hppa-tdep.c, osfsolib.c: Use this stuff.
 221         * convex-xdep.c, convex-tdep.c: Add FIXME's (getting the Convex
 222         signal code stuff right with the new signals would be non-trivial).
 223         * inferior.h (stop_signal): Make it enum target_signal not int.
 224         * target.c, target.h (target_signal_to_string, target_signal_to_name,
 225         target_signal_from_name): New functions.
 226         * inftarg.c, target.h (target_signal_to_host, target_signal_from_host,
 227         store_waitstatus): New functions.
 228         * procfs.c (procfs_notice_signals): Use them.
 229         * i960-tdep.c (i960_fault_to_signal): New function, to replace
 230         print_fault.
 231         * config/i960/tm-i960.h: Don't define PRINT_RANDOM_SIGNAL.
 232
 233         * objfiles.c (build_objfile_section_table): Don't abort() if
 234         objfile->sections is already set.
 235
 236         * objfiles.c (add_to_objfile_sections): Check SEC_ALLOC not SEC_LOAD
 237         to match recent change to exec.c.
 238
 239         * Version 4.11.3.
 240
 241         * main.c (print_gdb_version): Change year to 1994.
 242
 243         * ChangeLog, ChangeLog-93: Split ChangeLog at 1994.
 244         * Makefile.in (NONSRC): Add ChangeLog-93.
 245
 246 Mon Jan  3 11:57:29 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 247
 248         * stabsread.c (read_type): Allow defining several type numbers
 249         at once (e.g. "(1,2)=(3,4)="...).
 250
 251         * stabsread.c (read_enum_type): Use TARGET_INT_BIT not sizeof (int).
 252
 253         * breakpoint.c (frame_in_dummy): Check PC as well as frame.
 254
 255 Mon Jan  3 02:47:03 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 256
 257         * mdebugread.c (psymtab_to_symtab_1):  Only pass N_STAB symbols
 258         to process_one_symbol.
 259         * symtab.c (find_pc_psymbol):  Search global_psymbols as well to
 260         avoid caching a bad endaddr in find_pc_partial_function.
 261
 262 Sun Jan  2 21:41:17 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 263
 264         * config/m68k/tm-sun3.h: Don't define BELIEVE_PCC_PROMOTION.
 265

 267
 268         * infrun.c (wait_for_inferior):  Do not step or step resume past
 269         the end of a one-line function we just stepped into.
