 243         the user gets an immediate indication of where the target is.

 250         directly from Win32s and Win95.  Get rid of debugify crud.

 253         serial_send_break serial_close):  Merge common functionality into
 254         serial_logchar.  Clean up rest of routines.
 255         * sparclet-rom.c:  Disembowel.  Leave only download routine.
 256         Download routine now switches to remote target automatically.
 257         * top.c (disconnect):  Only define if SIGHUP is defined.  Cleans
 258         up MSVC/Win32 problem.
 259         * utils.c (gdb_flush):  Don't call hook unless it's for gdb_stdout
 260         or gdb_stderr.
 261         * config/sh/tm-sh.h:  Define TARGET_SH for WinGDB.

 274         operations.
 275         (gdbsim_wait, gdbsim_resume): Move call to sim_resume into
 276         sim_wait where gdb is in a position to handle a long running
 277         function.
 278         (gdbsim_cntrl_c): New function.  Wrap the sim_resume call in a
 279         SIGINT handler.

 333
 334 Mon Apr 14 16:25:10 1997  Ian Lance Taylor  <ian@cygnus.com>
 335
 336         * gdbserver/Makefile.in (INSTALL): Change install.sh to

 338
 339 Mon Apr 14 11:55:27 1997  Geoffrey Noer  <noer@pizza.cygnus.com>
 340
 341         * config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
 342         since gcc automatically includes it
 343
 344 Thu Apr 10 13:20:53 1997  Geoffrey Noer  <noer@cygnus.com>
 345
 346         * procfs.c: Substantial (but incomplete) changes to support
 347         sysv4.2mp procfs as implemented in UnixWare 2.1.  The procinfo
 348         struct now has substructs like struct flt_ctl instead of
 349         just a fltset_t and has a ctl_fd, status_fd, as_fd, and
 350         map_fd instead of a single fd.  Non-sysv4.2mp procfs models
 351         still have the structs and multiple fds, but don't use the
 352         entire struct and the four fds all point to the same thing.
 353         We use PROCFS_USE_READ_WRITE to decide whether to talk to
 354         procfs with reads/writes or use ioctl instead.  We use
 355         HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
 356         multiple fds or not.  PROC_NAME_FMT is split out into
 357         CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
 358         STATUS_PROC_NAME_FMT.
 359
 360         (procfs_notice_signals): now a necessary wrapper around
 361         (notice_signals): which are the new guts for noticing signals
 362         (open_proc_file): gets a new flag arg used in sysv4.2mp to
 363         determine whether or not to attempt to open the ctl_fd.
 364         (procfs_read_status): new local function, reads procfs status
 365         (procfs_write_pcwstop): new local function, writes a PCWSTOP
 366         (procfs_write_pckill): new local function, writes a PCKILL
 367         (unconditionally_kill_inferior): remove signo since we now
 368         just call procfs_write_pckill().
 369         (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
 370         (proc_iterate_over_mappings): the whole function is ifdefed
 371         on UNIXWARE to keep things readable.
 372
 373         Expanded the syscall_table to include new potential sysv4.2mp
 374         members.  Note that all ifdefs of UNIXWARE should be eliminated
 375         if possible or renamed to describe what's being selected for a
 376         bit better.  Sysv4.2mp and IRIX both have SYS_sproc so the
 377         IRIX specific code now also checks it's not UNIXWARE.
 378
 379         * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
 380         HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
 381         * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
 382         "/debug/%d" as PROC_NAME_FMT used to be
 383
 384 Wed Apr  9 11:36:14 1997  Jeffrey A Law  (law@cygnus.com)
 385
 386         * mn10300-tdep.c: Almost completely rewritten based on mn10200
 387         port.
 388         * config/mn10300/tm-mn10300.h: Likewise.
 389
 390 Tue Apr  8 10:45:24 1997  Stu Grossman  (grossman@critters.cygnus.com)
 391
 392         * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}:  Remove
 393         remote-pa.o from TDEPFILES.  Nobody uses it, and besides, it's a
 394         lousy out-of-date clone of remote.c.
 395
 396 Fri Apr  4 08:21:21 1997  Stu Grossman  (grossman@critters.cygnus.com)
 397
 398         * remote.c:  Fix problems realized while showering.
 399         * (hexnumlen):  Add prototype.  Use max, not min.
 400         * (remote_write_bytes remote_read_bytes):  Fix max packet size
 401         calculations to properly account for packet overhead.  Also handle
 402         (probably rare) case where remote_register_buf_size isn't set.
 403
 404         * remote.c:  Fix doc for `C' and `S' commands to indicate full
 405         address.
 406         * (remote_ops extended_remote_ops remote_desc remote_write_size):
 407         Make static.
 408         * (remote_fetch_registers remote_write_bytes remote_read_bytes):
 409         Record size of response to fetch registers command, use this to
 410         limit size of memory read and write commands.
 411         * (push_remote_target):  New function to make it possible to have
 412         another target switch to the remote target.
 413         * target.h:  Add prototype for push_remote_target.
 414         * sh-tdep.c (sh_frame_find_saved_regs):  Fix sign extension bugs
 415         for hosts which default to unsigned chars (such as SGI's).
 416         * (_initialize_sh_tdep):  Don't set remote_write_size.  It's now
 417         handled automatically in remote.c.
 418
 419 Thu Apr  3 15:10:30 1997  Michael Snyder  <msnyder@cleaver.cygnus.com>
 420
 421         * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
 422         find_pc_sect_function(), find_pc_sect_partial_function(): new
 423         functions for debugging overlays; pc without section is ambiguous.
 424         * breakpoint.[ch]: add section pointer to breakpoint struct;
 425         add section argument to check_duplicates(); check section as well
 426         as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
 427         breakpoint_thread_match(), bpstat_stop_status()];
 428         add section argument to describe_other_breakpoints();
 429         use INIT_SAL() macro to zero-out new sal structures;
 430         make resolve_sal_pc() fix up the sal's section as well as its pc;
 431         match on section + pc in clear_command() and delete_breakpoint();
 432         account for overlay sections in insert_breakpoints(),
 433         remove_breakpoint() and breakpoint_re_set_one();
 434         all this to support overlays where a PC is not unique.
 435         * exec.c: change xfer_memory() to handle overlay sections.
 436         * findvar.c: change read_var_value() to handle overlay sections.
 437         * frame.h: declaration for block_for_pc_sect() [blockframe.c].
 438         * infcmd.c: jump_command() warns against jumping into an overlay
 439         that's not in memory.  Also use INIT_SAL() to initialize sals.
 440         * infrun.c: wait_for_inferior() sets a flag to invalidate cached
 441         overlay state information; Also use INIT_SAL() to init sals.
 442         * m32r-rom.c: modify load routines to use LMA instead of VMA.
 443         * m32r-stub.c: mask exit value down to 8 bits; screen out any
 444         memory read/writes in the range 600000 to a00000, and ff680000
 445         to ff800000 (hangs because nothing is mapped there); fix strcpy().
 446         * maint.c: maintenance command "translate-address" supports overlays.
 447         * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
 448         * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
 449         this constitutes gdb's internal overlay mapping table.  Add macro
 450         ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
 451         Add function find_pc_sect_section().
 452         * printcmd.c: modify print_address_symbolic() with overlay smarts;
 453         modify address_info() with overlay smarts; add function sym_info()
 454         to support the INFO SYMBOL command (translate address to symbol(s));
 455         modify disassemble_command() to work on unmapped overlays.
 456         * source.c: use INIT_SAL() to initialize sals.
 457         * symfile.[ch]: change generic_load() to use section's LMA address
 458         instead of VMA address, for overlay sections.
 459         Add numerous functions for finding a PC's section / overlay,
 460         translating between VMA and LMA address ranges, determining if an
 461         overlay section is mapped, etc.  Add several user commands for
 462         overlay debugging.  Add support for a "generic" form of automatically
 463         reading overlay mapping info from the inferior (based on the default
 464         (simple) overlay manager which Cygnus provides as an example).
 465         * symtab.[ch]: add functions find_pc_sect_symtab(),
 466         find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
 467         for lookup; modify lookup_symbol and decode_line_1() to use them;
 468         modify find_function_start_sal() to account for overlay sections;
 469         add macro INIT_SAL() for initializing struct symtab_and_line.
 470         * target.c: fix a comment in the declaration of target_ops.

 479         new code to skip over MIPS16 thunks.
 480         (mips_frame_chain): Skip over MIPS16 thunks.
 481         * config/mips/tm-mips.h (mips_in_call_stub, mips_in_return_stub,
