  10         floatformat_ieee_double_littlebyte_bigword for little endian
  11         target byte order.
  12         * utils.c (floatformat_to_doublest): Create local preswapped
  13         copy of input for floatformat_littlebyte_bigword formats.

  15         the same as floatformat_little.
  16         (floatformat_from_doublest): Postswap output words for
  17         the floatformat_littlebyte_bigwords format.

  55
  56         * serial.c (serial_log_command):  Fix fputs_unfiltered calls.

  65         object file.
  66         (vmap_ldinfo, xcoff_relocate_core):  Adjust tstart by section offset
  67         of the text section, remove DONT_RELOCATE_SYMFILE_OBJFILE hack.
  68         (vmap_exec):  Relocate relative to the VMA in the object file,
  69         relocate .bss section as well.
  70         (xcoff_relocate_core):  No longer adjust section addresses by VMA.

  72         to CORE_ADDR.
  73         * xcoffread.c (secnum_to_bfd_section):  New routine to get
  74         BFD section from CS section number.
  75         (scan_xcoff_symtab):  Make toc_offset section relative.
  76
  77         * symtab.c (total_number_of_methods):  Avoid core dump if

  79
  80 Fri Apr 18 17:25:10 1997  Stu Grossman  (grossman@critters.cygnus.com)
  81
  82         * Makefile.in (SUBDIRS):  Add mswin so that make cleanup cleans up
  83         that directory.
  84         * defs.h utils.c (error warning):  Make message be const.
  85         * main.c (fputs_unfiltered):  Only send gdb_stdout and gdb_stderr
  86         to hook.  Otherwise send it to fputs.
  87         * monitor.c monitor.h (monitor_get_dev_name):  New function.  Does
  88         the obvious.
  89         * remote-e7000.c:  Remove debugify stuff.  Change printf, fprintf
  90         to _filtered forms to make output appear in GUIs.  Replace all
  91         uses of SERIAL_READCHAR with readchar, which has better error
  92         checking.
  93         * (e7000_parse_device):  Add prototype.
  94         (readchar):  Improve doc.  Handle random serial errors.
  95         (expect):  Disable notice_quit code.  It's busted.  Remove
  96         serial error handling (it's now handled in readchar).  Remove
  97         remote_debug echoing.  That's handled in readchar as well.
  98         (e7000_parse_device):  Remove serial_flag arg.  It's not
  99         necessary.
 100         (e7000_open):  Split into two pieces.  Second part is
 101         e7000_start_remote, and is error protected.  Now, when we connect
 102         to the target, we setup the initial frame and registers so that
 103         the user gets an immediate indication of where the target is.
 104         (gch):  Remove debug output.  That's handled by readchar.
 105         (e7000_read_inferior_memory):  Handle errors better.
 106         (_initialize_remote_e7000):  Get rid of `<xxx>' things from
 107         command names.  They show up when doing completion and confuse
 108         things horribly.
 109         * ser-e7kpc.c: Get rid of the DLL's since we can access the device
 110         directly from Win32s and Win95.  Get rid of debugify crud.
 111         * serial.c:  Remove debugify cruft.
 112         * (serial_logchar serial_log_command serial_write serial_readchar
 113         serial_send_break serial_close):  Merge common functionality into
 114         serial_logchar.  Clean up rest of routines.
 115         * sparclet-rom.c:  Disembowel.  Leave only download routine.
 116         Download routine now switches to remote target automatically.
 117         * top.c (disconnect):  Only define if SIGHUP is defined.  Cleans
 118         up MSVC/Win32 problem.
 119         * utils.c (gdb_flush):  Don't call hook unless it's for gdb_stdout
 120         or gdb_stderr.
 121         * config/sh/tm-sh.h:  Define TARGET_SH for WinGDB.
 122         * config/sparc/tm-sparclet.h:  Remove override for prompt.
 123
 124 Fri Apr 18 13:38:19 1997  Doug Evans  <dje@canuck.cygnus.com>
 125
 126         * remote-sim.c (gdbsim_open): Only pass -E to sim_open if
 127         TARGET_BYTE ORDER_SELECTABLE.
 128
 129 Fri Apr 18 16:52:41 1997  Andrew Cagney  <cagney@b1.cygnus.com>
 130
 131         * remote-sim.c (init_callbacks): Initialize poll_quit and magic
 132         fields of gdb_callback.
 133         (gdbsim_stop): Add gdbsim_stop to list of supported client
 134         operations.
 135         (gdbsim_wait, gdbsim_resume): Move call to sim_resume into
 136         sim_wait where gdb is in a position to handle a long running
 137         function.
 138         (gdbsim_cntrl_c): New function.  Wrap the sim_resume call in a
 139         SIGINT handler.
 140         (gdb_os_poll_quit): New function. Check for a quit pending on the
 141         console.

 144 Wed Apr 16 12:33:06 1997  Andrew Cagney  <cagney@b1.cygnus.com>
 145
 146         * Makefile.in (install-only): Make list of gdbtcl files to install
 147         explicit - was picking up files such as ChangeLog etc.
 148         (install-only): Don't blindly create the directory.
 149

 151 Thu Apr 17 14:30:04 1997  Per Bothner  <bothner@deneb.cygnus.com>
 152
 153         * defs.h (enum language):  Add language_java.
 154         * java-exp.y, java-lang.c, java-lang.h, java-valprint.c:  New files.
 155         * Makefile.in:  Update for new files.
 156         * objfiles.c (allocate_objfile):  Allow NULL bfd argument.
 157         * symfile.c (deduce_language_from_filename):  Recognize .java.

 159 Thu Apr 17 02:20:23 1997  Doug Evans  <dje@canuck.cygnus.com>
 160
 161         * m32r-stub.c (stash_registers): Rewrite.
 162         (restore_registers): Renamed to restore_and_return.
 163         (cleanup_stash): New function.
 164         (process_exception): New function.
 165         (_catchException*): Rewrite.
 166
 167         * remote-sim.c (gdbsim_load): Update call to sim_load.
 168         (gdbsim_create_inferior): No longer pass start_address to
 169         sim_create_inferior.

 172 Tue Apr 15 15:31:09 1997  Stan Shebs  <shebs@andros.cygnus.com>
 173
 174         * remote.c (get_offsets): Don't use scanf for interpreting
 175         response to qOffsets.
 176
 177 Tue Apr 15 14:51:04 1997  Ian Lance Taylor  <ian@cygnus.com>
 178
 179         * gdbserver/Makefile.in (INSTALL_XFORM): Remove.
 180         (INSTALL_XFORM1): Remove.
 181         (install-only): Use $(program_transform_name) directly, rather
 182         than using $(INSTALL_XFORM) and $(INSTALL_XFORM1).
 183         (uninstall): Transform name.
 184
 185 Mon Apr 14 17:06:27 1997  Mark Alexander  <marka@cygnus.com>
 186
 187         * remote-mips.c (mips_load): Ensure that PC gets updated
 188         after a load on LSI target.
 189
 190 Mon Apr 14 15:54:51 1997  Geoffrey Noer  <noer@pizza.cygnus.com>
 191
 192         * procfs.c (notice_signals): fix typo
 193
 194 Mon Apr 14 16:25:10 1997  Ian Lance Taylor  <ian@cygnus.com>
 195
 196         * gdbserver/Makefile.in (INSTALL): Change install.sh to
 197         install-sh.
 198
 199 Mon Apr 14 11:55:27 1997  Geoffrey Noer  <noer@pizza.cygnus.com>
 200
 201         * config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
 202         since gcc automatically includes it
 203
 204 Thu Apr 10 13:20:53 1997  Geoffrey Noer  <noer@cygnus.com>
 205
 206         * procfs.c: Substantial (but incomplete) changes to support
 207         sysv4.2mp procfs as implemented in UnixWare 2.1.  The procinfo
 208         struct now has substructs like struct flt_ctl instead of
 209         just a fltset_t and has a ctl_fd, status_fd, as_fd, and
 210         map_fd instead of a single fd.  Non-sysv4.2mp procfs models
 211         still have the structs and multiple fds, but don't use the
 212         entire struct and the four fds all point to the same thing.
 213         We use PROCFS_USE_READ_WRITE to decide whether to talk to
 214         procfs with reads/writes or use ioctl instead.  We use
 215         HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
 216         multiple fds or not.  PROC_NAME_FMT is split out into
 217         CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
 218         STATUS_PROC_NAME_FMT.
 219
 220         (procfs_notice_signals): now a necessary wrapper around
 221         (notice_signals): which are the new guts for noticing signals
 222         (open_proc_file): gets a new flag arg used in sysv4.2mp to
 223         determine whether or not to attempt to open the ctl_fd.
 224         (procfs_read_status): new local function, reads procfs status
 225         (procfs_write_pcwstop): new local function, writes a PCWSTOP
 226         (procfs_write_pckill): new local function, writes a PCKILL
 227         (unconditionally_kill_inferior): remove signo since we now
 228         just call procfs_write_pckill().
 229         (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
 230         (proc_iterate_over_mappings): the whole function is ifdefed
 231         on UNIXWARE to keep things readable.
 232
 233         Expanded the syscall_table to include new potential sysv4.2mp
 234         members.  Note that all ifdefs of UNIXWARE should be eliminated
 235         if possible or renamed to describe what's being selected for a
 236         bit better.  Sysv4.2mp and IRIX both have SYS_sproc so the
 237         IRIX specific code now also checks it's not UNIXWARE.
 238
 239         * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
 240         HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
 241         * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
 242         "/debug/%d" as PROC_NAME_FMT used to be
 243
 244 Wed Apr  9 11:36:14 1997  Jeffrey A Law  (law@cygnus.com)
 245
 246         * mn10300-tdep.c: Almost completely rewritten based on mn10200
 247         port.
 248         * config/mn10300/tm-mn10300.h: Likewise.
 249
 250 Tue Apr  8 10:45:24 1997  Stu Grossman  (grossman@critters.cygnus.com)
 251
 252         * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}:  Remove
 253         remote-pa.o from TDEPFILES.  Nobody uses it, and besides, it's a
 254         lousy out-of-date clone of remote.c.
 255
 256 Fri Apr  4 08:21:21 1997  Stu Grossman  (grossman@critters.cygnus.com)
 257
 258         * remote.c:  Fix problems realized while showering.
 259         * (hexnumlen):  Add prototype.  Use max, not min.
 260         * (remote_write_bytes remote_read_bytes):  Fix max packet size
 261         calculations to properly account for packet overhead.  Also handle
 262         (probably rare) case where remote_register_buf_size isn't set.
 263
 264         * remote.c:  Fix doc for `C' and `S' commands to indicate full
 265         address.
 266         * (remote_ops extended_remote_ops remote_desc remote_write_size):
 267         Make static.
 268         * (remote_fetch_registers remote_write_bytes remote_read_bytes):
 269         Record size of response to fetch registers command, use this to
 270         limit size of memory read and write commands.
 271         * (push_remote_target):  New function to make it possible to have
 272         another target switch to the remote target.
 273         * target.h:  Add prototype for push_remote_target.
 274         * sh-tdep.c (sh_frame_find_saved_regs):  Fix sign extension bugs
 275         for hosts which default to unsigned chars (such as SGI's).
 276         * (_initialize_sh_tdep):  Don't set remote_write_size.  It's now
 277         handled automatically in remote.c.
 278
 279 Thu Apr  3 15:10:30 1997  Michael Snyder  <msnyder@cleaver.cygnus.com>
 280
 281         * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
 282         find_pc_sect_function(), find_pc_sect_partial_function(): new
 283         functions for debugging overlays; pc without section is ambiguous.
 284         * breakpoint.[ch]: add section pointer to breakpoint struct;
 285         add section argument to check_duplicates(); check section as well
 286         as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
 287         breakpoint_thread_match(), bpstat_stop_status()];
 288         add section argument to describe_other_breakpoints();
 289         use INIT_SAL() macro to zero-out new sal structures;
 290         make resolve_sal_pc() fix up the sal's section as well as its pc;
 291         match on section + pc in clear_command() and delete_breakpoint();
 292         account for overlay sections in insert_breakpoints(),
 293         remove_breakpoint() and breakpoint_re_set_one();
 294         all this to support overlays where a PC is not unique.
 295         * exec.c: change xfer_memory() to handle overlay sections.
 296         * findvar.c: change read_var_value() to handle overlay sections.
 297         * frame.h: declaration for block_for_pc_sect() [blockframe.c].
 298         * infcmd.c: jump_command() warns against jumping into an overlay
 299         that's not in memory.  Also use INIT_SAL() to initialize sals.
 300         * infrun.c: wait_for_inferior() sets a flag to invalidate cached
 301         overlay state information; Also use INIT_SAL() to init sals.
 302         * m32r-rom.c: modify load routines to use LMA instead of VMA.
 303         * m32r-stub.c: mask exit value down to 8 bits; screen out any
 304         memory read/writes in the range 600000 to a00000, and ff680000
 305         to ff800000 (hangs because nothing is mapped there); fix strcpy().
 306         * maint.c: maintenance command "translate-address" supports overlays.
 307         * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
 308         * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
 309         this constitutes gdb's internal overlay mapping table.  Add macro
 310         ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
 311         Add function find_pc_sect_section().
 312         * printcmd.c: modify print_address_symbolic() with overlay smarts;
 313         modify address_info() with overlay smarts; add function sym_info()
 314         to support the INFO SYMBOL command (translate address to symbol(s));
 315         modify disassemble_command() to work on unmapped overlays.
 316         * source.c: use INIT_SAL() to initialize sals.
