  26
  27         * java-exp.y:  Combine TRUE and FALSE into BOOLEAN_LITERAL.

  31
  32         * serial.c (serial_log_command):  Fix fputs_unfiltered calls.
  33
  34         * config/powerpc/tm-ppc-aix4.h, config/rs6000/tm-rs6000-aix4.h

  39         tstart and dstart with section VMA.
  40         * rs6000-nat.c (vmap_symtab):  Relocate relative to the VMA in the
  41         object file.
  42         (vmap_ldinfo, xcoff_relocate_core):  Adjust tstart by section offset
  43         of the text section, remove DONT_RELOCATE_SYMFILE_OBJFILE hack.
  44         (vmap_exec):  Relocate relative to the VMA in the object file,
  45         relocate .bss section as well.
  46         (xcoff_relocate_core):  No longer adjust section addresses by VMA.
  47         * rs6000-tdep.c (find_toc_address):  Change type of tocbase
  48         to CORE_ADDR.
  49         * xcoffread.c (secnum_to_bfd_section):  New routine to get
  50         BFD section from CS section number.
  51         (scan_xcoff_symtab):  Make toc_offset section relative.
  52
  53         * symtab.c (total_number_of_methods):  Avoid core dump if
  54         baseclass type is still undefined.
  55
  56 Fri Apr 18 17:25:10 1997  Stu Grossman  (grossman@critters.cygnus.com)
  57
  58         * Makefile.in (SUBDIRS):  Add mswin so that make cleanup cleans up
  59         that directory.
  60         * defs.h utils.c (error warning):  Make message be const.
  61         * main.c (fputs_unfiltered):  Only send gdb_stdout and gdb_stderr
  62         to hook.  Otherwise send it to fputs.
  63         * monitor.c monitor.h (monitor_get_dev_name):  New function.  Does
  64         the obvious.
  65         * remote-e7000.c:  Remove debugify stuff.  Change printf, fprintf
  66         to _filtered forms to make output appear in GUIs.  Replace all
  67         uses of SERIAL_READCHAR with readchar, which has better error
  68         checking.
  69         * (e7000_parse_device):  Add prototype.
  70         (readchar):  Improve doc.  Handle random serial errors.
  71         (expect):  Disable notice_quit code.  It's busted.  Remove
  72         serial error handling (it's now handled in readchar).  Remove
  73         remote_debug echoing.  That's handled in readchar as well.
  74         (e7000_parse_device):  Remove serial_flag arg.  It's not
  75         necessary.
  76         (e7000_open):  Split into two pieces.  Second part is
  77         e7000_start_remote, and is error protected.  Now, when we connect
  78         to the target, we setup the initial frame and registers so that
  79         the user gets an immediate indication of where the target is.
  80         (gch):  Remove debug output.  That's handled by readchar.
  81         (e7000_read_inferior_memory):  Handle errors better.
  82         (_initialize_remote_e7000):  Get rid of `<xxx>' things from
  83         command names.  They show up when doing completion and confuse
  84         things horribly.
  85         * ser-e7kpc.c: Get rid of the DLL's since we can access the device
  86         directly from Win32s and Win95.  Get rid of debugify crud.
  87         * serial.c:  Remove debugify cruft.
  88         * (serial_logchar serial_log_command serial_write serial_readchar
  89         serial_send_break serial_close):  Merge common functionality into
  90         serial_logchar.  Clean up rest of routines.
  91         * sparclet-rom.c:  Disembowel.  Leave only download routine.
  92         Download routine now switches to remote target automatically.
  93         * top.c (disconnect):  Only define if SIGHUP is defined.  Cleans
  94         up MSVC/Win32 problem.
  95         * utils.c (gdb_flush):  Don't call hook unless it's for gdb_stdout
  96         or gdb_stderr.
  97         * config/sh/tm-sh.h:  Define TARGET_SH for WinGDB.
  98         * config/sparc/tm-sparclet.h:  Remove override for prompt.

 100 Fri Apr 18 13:38:19 1997  Doug Evans  <dje@canuck.cygnus.com>
 101
 102         * remote-sim.c (gdbsim_open): Only pass -E to sim_open if
 103         TARGET_BYTE ORDER_SELECTABLE.
 104
 105 Fri Apr 18 16:52:41 1997  Andrew Cagney  <cagney@b1.cygnus.com>
 106
 107         * remote-sim.c (init_callbacks): Initialize poll_quit and magic
 108         fields of gdb_callback.
 109         (gdbsim_stop): Add gdbsim_stop to list of supported client
 110         operations.
 111         (gdbsim_wait, gdbsim_resume): Move call to sim_resume into
 112         sim_wait where gdb is in a position to handle a long running
 113         function.
 114         (gdbsim_cntrl_c): New function.  Wrap the sim_resume call in a
 115         SIGINT handler.
 116         (gdb_os_poll_quit): New function. Check for a quit pending on the
 117         console.

 120 Wed Apr 16 12:33:06 1997  Andrew Cagney  <cagney@b1.cygnus.com>
 121
 122         * Makefile.in (install-only): Make list of gdbtcl files to install
 123         explicit - was picking up files such as ChangeLog etc.
 124         (install-only): Don't blindly create the directory.
 125

 127 Thu Apr 17 14:30:04 1997  Per Bothner  <bothner@deneb.cygnus.com>
 128
 129         * defs.h (enum language):  Add language_java.
 130         * java-exp.y, java-lang.c, java-lang.h, java-valprint.c:  New files.
 131         * Makefile.in:  Update for new files.
 132         * objfiles.c (allocate_objfile):  Allow NULL bfd argument.
 133         * symfile.c (deduce_language_from_filename):  Recognize .java.
 134
 135 Thu Apr 17 02:20:23 1997  Doug Evans  <dje@canuck.cygnus.com>
 136
 137         * m32r-stub.c (stash_registers): Rewrite.
 138         (restore_registers): Renamed to restore_and_return.
 139         (cleanup_stash): New function.
 140         (process_exception): New function.
 141         (_catchException*): Rewrite.
 142
 143         * remote-sim.c (gdbsim_load): Update call to sim_load.
 144         (gdbsim_create_inferior): No longer pass start_address to
 145         sim_create_inferior.
 146         (gdbsim_open): Pass endian indicator as arg.
 147
 148 Tue Apr 15 15:31:09 1997  Stan Shebs  <shebs@andros.cygnus.com>
 149
 150         * remote.c (get_offsets): Don't use scanf for interpreting
 151         response to qOffsets.
 152
 153 Tue Apr 15 14:51:04 1997  Ian Lance Taylor  <ian@cygnus.com>
 154
 155         * gdbserver/Makefile.in (INSTALL_XFORM): Remove.
 156         (INSTALL_XFORM1): Remove.
 157         (install-only): Use $(program_transform_name) directly, rather
 158         than using $(INSTALL_XFORM) and $(INSTALL_XFORM1).
 159         (uninstall): Transform name.
 160
 161 Mon Apr 14 17:06:27 1997  Mark Alexander  <marka@cygnus.com>
 162
 163         * remote-mips.c (mips_load): Ensure that PC gets updated
 164         after a load on LSI target.
 165
 166 Mon Apr 14 15:54:51 1997  Geoffrey Noer  <noer@pizza.cygnus.com>
 167
 168         * procfs.c (notice_signals): fix typo
 169
 170 Mon Apr 14 16:25:10 1997  Ian Lance Taylor  <ian@cygnus.com>
 171
 172         * gdbserver/Makefile.in (INSTALL): Change install.sh to
 173         install-sh.
 174
 175 Mon Apr 14 11:55:27 1997  Geoffrey Noer  <noer@pizza.cygnus.com>
 176
 177         * config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
 178         since gcc automatically includes it
 179
 180 Thu Apr 10 13:20:53 1997  Geoffrey Noer  <noer@cygnus.com>
 181
 182         * procfs.c: Substantial (but incomplete) changes to support
 183         sysv4.2mp procfs as implemented in UnixWare 2.1.  The procinfo
 184         struct now has substructs like struct flt_ctl instead of
 185         just a fltset_t and has a ctl_fd, status_fd, as_fd, and
 186         map_fd instead of a single fd.  Non-sysv4.2mp procfs models
 187         still have the structs and multiple fds, but don't use the
 188         entire struct and the four fds all point to the same thing.
 189         We use PROCFS_USE_READ_WRITE to decide whether to talk to
 190         procfs with reads/writes or use ioctl instead.  We use
 191         HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
 192         multiple fds or not.  PROC_NAME_FMT is split out into
 193         CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
 194         STATUS_PROC_NAME_FMT.
 195
 196         (procfs_notice_signals): now a necessary wrapper around
 197         (notice_signals): which are the new guts for noticing signals
 198         (open_proc_file): gets a new flag arg used in sysv4.2mp to
 199         determine whether or not to attempt to open the ctl_fd.
 200         (procfs_read_status): new local function, reads procfs status
 201         (procfs_write_pcwstop): new local function, writes a PCWSTOP
 202         (procfs_write_pckill): new local function, writes a PCKILL
 203         (unconditionally_kill_inferior): remove signo since we now
 204         just call procfs_write_pckill().
 205         (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
 206         (proc_iterate_over_mappings): the whole function is ifdefed
 207         on UNIXWARE to keep things readable.
 208
 209         Expanded the syscall_table to include new potential sysv4.2mp
 210         members.  Note that all ifdefs of UNIXWARE should be eliminated
 211         if possible or renamed to describe what's being selected for a
 212         bit better.  Sysv4.2mp and IRIX both have SYS_sproc so the
 213         IRIX specific code now also checks it's not UNIXWARE.
 214
 215         * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
 216         HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
 217         * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
 218         "/debug/%d" as PROC_NAME_FMT used to be
 219
 220 Wed Apr  9 11:36:14 1997  Jeffrey A Law  (law@cygnus.com)
 221
 222         * mn10300-tdep.c: Almost completely rewritten based on mn10200
 223         port.
 224         * config/mn10300/tm-mn10300.h: Likewise.
 225
 226 Tue Apr  8 10:45:24 1997  Stu Grossman  (grossman@critters.cygnus.com)
 227
 228         * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}:  Remove
 229         remote-pa.o from TDEPFILES.  Nobody uses it, and besides, it's a
 230         lousy out-of-date clone of remote.c.
 231
 232 Fri Apr  4 08:21:21 1997  Stu Grossman  (grossman@critters.cygnus.com)
 233
 234         * remote.c:  Fix problems realized while showering.
 235         * (hexnumlen):  Add prototype.  Use max, not min.
 236         * (remote_write_bytes remote_read_bytes):  Fix max packet size
 237         calculations to properly account for packet overhead.  Also handle
 238         (probably rare) case where remote_register_buf_size isn't set.
 239
 240         * remote.c:  Fix doc for `C' and `S' commands to indicate full
 241         address.
 242         * (remote_ops extended_remote_ops remote_desc remote_write_size):
 243         Make static.
 244         * (remote_fetch_registers remote_write_bytes remote_read_bytes):
 245         Record size of response to fetch registers command, use this to
 246         limit size of memory read and write commands.
 247         * (push_remote_target):  New function to make it possible to have
 248         another target switch to the remote target.
 249         * target.h:  Add prototype for push_remote_target.
 250         * sh-tdep.c (sh_frame_find_saved_regs):  Fix sign extension bugs
 251         for hosts which default to unsigned chars (such as SGI's).
 252         * (_initialize_sh_tdep):  Don't set remote_write_size.  It's now
 253         handled automatically in remote.c.
 254
 255 Thu Apr  3 15:10:30 1997  Michael Snyder  <msnyder@cleaver.cygnus.com>
 256
 257         * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
 258         find_pc_sect_function(), find_pc_sect_partial_function(): new
 259         functions for debugging overlays; pc without section is ambiguous.
 260         * breakpoint.[ch]: add section pointer to breakpoint struct;
 261         add section argument to check_duplicates(); check section as well
 262         as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
 263         breakpoint_thread_match(), bpstat_stop_status()];
 264         add section argument to describe_other_breakpoints();
 265         use INIT_SAL() macro to zero-out new sal structures;
 266         make resolve_sal_pc() fix up the sal's section as well as its pc;
 267         match on section + pc in clear_command() and delete_breakpoint();
 268         account for overlay sections in insert_breakpoints(),
 269         remove_breakpoint() and breakpoint_re_set_one();
 270         all this to support overlays where a PC is not unique.
 271         * exec.c: change xfer_memory() to handle overlay sections.
 272         * findvar.c: change read_var_value() to handle overlay sections.
 273         * frame.h: declaration for block_for_pc_sect() [blockframe.c].
 274         * infcmd.c: jump_command() warns against jumping into an overlay
 275         that's not in memory.  Also use INIT_SAL() to initialize sals.
 276         * infrun.c: wait_for_inferior() sets a flag to invalidate cached
 277         overlay state information; Also use INIT_SAL() to init sals.
 278         * m32r-rom.c: modify load routines to use LMA instead of VMA.
 279         * m32r-stub.c: mask exit value down to 8 bits; screen out any
 280         memory read/writes in the range 600000 to a00000, and ff680000
 281         to ff800000 (hangs because nothing is mapped there); fix strcpy().
 282         * maint.c: maintenance command "translate-address" supports overlays.
 283         * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
 284         * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
 285         this constitutes gdb's internal overlay mapping table.  Add macro
 286         ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
 287         Add function find_pc_sect_section().
 288         * printcmd.c: modify print_address_symbolic() with overlay smarts;
 289         modify address_info() with overlay smarts; add function sym_info()
 290         to support the INFO SYMBOL command (translate address to symbol(s));
 291         modify disassemble_command() to work on unmapped overlays.
 292         * source.c: use INIT_SAL() to initialize sals.
 293         * symfile.[ch]: change generic_load() to use section's LMA address
 294         instead of VMA address, for overlay sections.
 295         Add numerous functions for finding a PC's section / overlay,
 296         translating between VMA and LMA address ranges, determining if an
 297         overlay section is mapped, etc.  Add several user commands for
 298         overlay debugging.  Add support for a "generic" form of automatically
 299         reading overlay mapping info from the inferior (based on the default
 300         (simple) overlay manager which Cygnus provides as an example).
 301         * symtab.[ch]: add functions find_pc_sect_symtab(),
 302         find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
 303         for lookup; modify lookup_symbol and decode_line_1() to use them;
 304         modify find_function_start_sal() to account for overlay sections;
 305         add macro INIT_SAL() for initializing struct symtab_and_line.
 306         * target.c: fix a comment in the declaration of target_ops.
 307
 308 Thu Apr  3 10:31:12 1997  Mark Alexander  <marka@cygnus.com>
 309
 310         * mips-tdep.c (mips_in_call_stub, mips_in_return_stub,
 311         mips_skip_stub, mips_ignore_helper): New functions for dealing
 312         with MIPS16 call/return thunks.
