  79         (vmap_exec):  Relocate relative to the VMA in the object file,
  80         relocate .bss section as well.
  81         (xcoff_relocate_core):  No longer adjust section addresses by VMA.

  83         to CORE_ADDR.
  84         * xcoffread.c (secnum_to_bfd_section):  New routine to get
  85         BFD section from CS section number.
  86         (scan_xcoff_symtab):  Make toc_offset section relative.

  90
  91 Fri Apr 18 17:25:10 1997  Stu Grossman  (grossman@critters.cygnus.com)
  92
  93         * Makefile.in (SUBDIRS):  Add mswin so that make cleanup cleans up
  94         that directory.
  95         * defs.h utils.c (error warning):  Make message be const.
  96         * main.c (fputs_unfiltered):  Only send gdb_stdout and gdb_stderr
  97         to hook.  Otherwise send it to fputs.
  98         * monitor.c monitor.h (monitor_get_dev_name):  New function.  Does
  99         the obvious.
 100         * remote-e7000.c:  Remove debugify stuff.  Change printf, fprintf
 101         to _filtered forms to make output appear in GUIs.  Replace all
 102         uses of SERIAL_READCHAR with readchar, which has better error
 103         checking.
 104         * (e7000_parse_device):  Add prototype.
 105         (readchar):  Improve doc.  Handle random serial errors.
 106         (expect):  Disable notice_quit code.  It's busted.  Remove
 107         serial error handling (it's now handled in readchar).  Remove
 108         remote_debug echoing.  That's handled in readchar as well.
 109         (e7000_parse_device):  Remove serial_flag arg.  It's not
 110         necessary.
 111         (e7000_open):  Split into two pieces.  Second part is
 112         e7000_start_remote, and is error protected.  Now, when we connect
 113         to the target, we setup the initial frame and registers so that
 114         the user gets an immediate indication of where the target is.
 115         (gch):  Remove debug output.  That's handled by readchar.
 116         (e7000_read_inferior_memory):  Handle errors better.
 117         (_initialize_remote_e7000):  Get rid of `<xxx>' things from
 118         command names.  They show up when doing completion and confuse
 119         things horribly.
 120         * ser-e7kpc.c: Get rid of the DLL's since we can access the device
 121         directly from Win32s and Win95.  Get rid of debugify crud.
 122         * serial.c:  Remove debugify cruft.
 123         * (serial_logchar serial_log_command serial_write serial_readchar
 124         serial_send_break serial_close):  Merge common functionality into
 125         serial_logchar.  Clean up rest of routines.
 126         * sparclet-rom.c:  Disembowel.  Leave only download routine.
 127         Download routine now switches to remote target automatically.
 128         * top.c (disconnect):  Only define if SIGHUP is defined.  Cleans
 129         up MSVC/Win32 problem.
 130         * utils.c (gdb_flush):  Don't call hook unless it's for gdb_stdout
 131         or gdb_stderr.
 132         * config/sh/tm-sh.h:  Define TARGET_SH for WinGDB.
 133         * config/sparc/tm-sparclet.h:  Remove override for prompt.

 135 Fri Apr 18 13:38:19 1997  Doug Evans  <dje@canuck.cygnus.com>
 136
 137         * remote-sim.c (gdbsim_open): Only pass -E to sim_open if
 138         TARGET_BYTE ORDER_SELECTABLE.
 139
 140 Fri Apr 18 16:52:41 1997  Andrew Cagney  <cagney@b1.cygnus.com>
 141
 142         * remote-sim.c (init_callbacks): Initialize poll_quit and magic
 143         fields of gdb_callback.
 144         (gdbsim_stop): Add gdbsim_stop to list of supported client
 145         operations.
 146         (gdbsim_wait, gdbsim_resume): Move call to sim_resume into
 147         sim_wait where gdb is in a position to handle a long running
 148         function.
 149         (gdbsim_cntrl_c): New function.  Wrap the sim_resume call in a
 150         SIGINT handler.
 151         (gdb_os_poll_quit): New function. Check for a quit pending on the
 152         console.

 155 Wed Apr 16 12:33:06 1997  Andrew Cagney  <cagney@b1.cygnus.com>
 156
 157         * Makefile.in (install-only): Make list of gdbtcl files to install
 158         explicit - was picking up files such as ChangeLog etc.
 159         (install-only): Don't blindly create the directory.

 165         * java-exp.y, java-lang.c, java-lang.h, java-valprint.c:  New files.
 166         * Makefile.in:  Update for new files.
 167         * objfiles.c (allocate_objfile):  Allow NULL bfd argument.
 168         * symfile.c (deduce_language_from_filename):  Recognize .java.

 191         (INSTALL_XFORM1): Remove.
 192         (install-only): Use $(program_transform_name) directly, rather
 193         than using $(INSTALL_XFORM) and $(INSTALL_XFORM1).
 194         (uninstall): Transform name.

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

 331         translating between VMA and LMA address ranges, determining if an
 332         overlay section is mapped, etc.  Add several user commands for
 333         overlay debugging.  Add support for a "generic" form of automatically
 334         reading overlay mapping info from the inferior (based on the default
 335         (simple) overlay manager which Cygnus provides as an example).
 336         * symtab.[ch]: add functions find_pc_sect_symtab(),
 337         find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()

 339         modify find_function_start_sal() to account for overlay sections;
 340         add macro INIT_SAL() for initializing struct symtab_and_line.
