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

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

 269         operations.
 270         (gdbsim_wait, gdbsim_resume): Move call to sim_resume into
 271         sim_wait where gdb is in a position to handle a long running
 272         function.
 273         (gdbsim_cntrl_c): New function.  Wrap the sim_resume call in a
 274         SIGINT handler.

 335
 336         * config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
 337         since gcc automatically includes it
 338
 339 Thu Apr 10 13:20:53 1997  Geoffrey Noer  <noer@cygnus.com>
 340
 341         * procfs.c: Substantial (but incomplete) changes to support
 342         sysv4.2mp procfs as implemented in UnixWare 2.1.  The procinfo
 343         struct now has substructs like struct flt_ctl instead of
 344         just a fltset_t and has a ctl_fd, status_fd, as_fd, and
 345         map_fd instead of a single fd.  Non-sysv4.2mp procfs models
 346         still have the structs and multiple fds, but don't use the
 347         entire struct and the four fds all point to the same thing.
 348         We use PROCFS_USE_READ_WRITE to decide whether to talk to
 349         procfs with reads/writes or use ioctl instead.  We use
 350         HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
 351         multiple fds or not.  PROC_NAME_FMT is split out into
 352         CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
 353         STATUS_PROC_NAME_FMT.
 354
 355         (procfs_notice_signals): now a necessary wrapper around
 356         (notice_signals): which are the new guts for noticing signals
 357         (open_proc_file): gets a new flag arg used in sysv4.2mp to
 358         determine whether or not to attempt to open the ctl_fd.
 359         (procfs_read_status): new local function, reads procfs status
 360         (procfs_write_pcwstop): new local function, writes a PCWSTOP
 361         (procfs_write_pckill): new local function, writes a PCKILL
 362         (unconditionally_kill_inferior): remove signo since we now
 363         just call procfs_write_pckill().
 364         (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
 365         (proc_iterate_over_mappings): the whole function is ifdefed
 366         on UNIXWARE to keep things readable.
 367
 368         Expanded the syscall_table to include new potential sysv4.2mp
 369         members.  Note that all ifdefs of UNIXWARE should be eliminated
 370         if possible or renamed to describe what's being selected for a
 371         bit better.  Sysv4.2mp and IRIX both have SYS_sproc so the
 372         IRIX specific code now also checks it's not UNIXWARE.
 373
 374         * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
 375         HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
 376         * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
 377         "/debug/%d" as PROC_NAME_FMT used to be
 378
 379 Wed Apr  9 11:36:14 1997  Jeffrey A Law  (law@cygnus.com)
 380
 381         * mn10300-tdep.c: Almost completely rewritten based on mn10200
 382         port.
 383         * config/mn10300/tm-mn10300.h: Likewise.

 385 Tue Apr  8 10:45:24 1997  Stu Grossman  (grossman@critters.cygnus.com)
 386
 387         * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}:  Remove
 388         remote-pa.o from TDEPFILES.  Nobody uses it, and besides, it's a
 389         lousy out-of-date clone of remote.c.

 391 Fri Apr  4 08:21:21 1997  Stu Grossman  (grossman@critters.cygnus.com)
 392
 393         * remote.c:  Fix problems realized while showering.
 394         * (hexnumlen):  Add prototype.  Use max, not min.
 395         * (remote_write_bytes remote_read_bytes):  Fix max packet size
 396         calculations to properly account for packet overhead.  Also handle
 397         (probably rare) case where remote_register_buf_size isn't set.
 398
 399         * remote.c:  Fix doc for `C' and `S' commands to indicate full
 400         address.
 401         * (remote_ops extended_remote_ops remote_desc remote_write_size):
 402         Make static.
 403         * (remote_fetch_registers remote_write_bytes remote_read_bytes):
 404         Record size of response to fetch registers command, use this to
 405         limit size of memory read and write commands.
 406         * (push_remote_target):  New function to make it possible to have
 407         another target switch to the remote target.
 408         * target.h:  Add prototype for push_remote_target.
 409         * sh-tdep.c (sh_frame_find_saved_regs):  Fix sign extension bugs
 410         for hosts which default to unsigned chars (such as SGI's).
 411         * (_initialize_sh_tdep):  Don't set remote_write_size.  It's now
 412         handled automatically in remote.c.

 415
 416         * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
 417         find_pc_sect_function(), find_pc_sect_partial_function(): new
 418         functions for debugging overlays; pc without section is ambiguous.
 419         * breakpoint.[ch]: add section pointer to breakpoint struct;
 420         add section argument to check_duplicates(); check section as well
 421         as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
 422         breakpoint_thread_match(), bpstat_stop_status()];
 423         add section argument to describe_other_breakpoints();
 424         use INIT_SAL() macro to zero-out new sal structures;
 425         make resolve_sal_pc() fix up the sal's section as well as its pc;
 426         match on section + pc in clear_command() and delete_breakpoint();
 427         account for overlay sections in insert_breakpoints(),
 428         remove_breakpoint() and breakpoint_re_set_one();
 429         all this to support overlays where a PC is not unique.
 430         * exec.c: change xfer_memory() to handle overlay sections.
 431         * findvar.c: change read_var_value() to handle overlay sections.
 432         * frame.h: declaration for block_for_pc_sect() [blockframe.c].
 433         * infcmd.c: jump_command() warns against jumping into an overlay
 434         that's not in memory.  Also use INIT_SAL() to initialize sals.
 435         * infrun.c: wait_for_inferior() sets a flag to invalidate cached
 436         overlay state information; Also use INIT_SAL() to init sals.
 437         * m32r-rom.c: modify load routines to use LMA instead of VMA.
 438         * m32r-stub.c: mask exit value down to 8 bits; screen out any
 439         memory read/writes in the range 600000 to a00000, and ff680000
 440         to ff800000 (hangs because nothing is mapped there); fix strcpy().
 441         * maint.c: maintenance command "translate-address" supports overlays.
 442         * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
 443         * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
 444         this constitutes gdb's internal overlay mapping table.  Add macro
 445         ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
 446         Add function find_pc_sect_section().
 447         * printcmd.c: modify print_address_symbolic() with overlay smarts;
 448         modify address_info() with overlay smarts; add function sym_info()
 449         to support the INFO SYMBOL command (translate address to symbol(s));
 450         modify disassemble_command() to work on unmapped overlays.
 451         * source.c: use INIT_SAL() to initialize sals.
 452         * symfile.[ch]: change generic_load() to use section's LMA address
 453         instead of VMA address, for overlay sections.
 454         Add numerous functions for finding a PC's section / overlay,
 455         translating between VMA and LMA address ranges, determining if an
 456         overlay section is mapped, etc.  Add several user commands for
 457         overlay debugging.  Add support for a "generic" form of automatically
 458         reading overlay mapping info from the inferior (based on the default
 459         (simple) overlay manager which Cygnus provides as an example).
 460         * symtab.[ch]: add functions find_pc_sect_symtab(),
 461         find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
 462         for lookup; modify lookup_symbol and decode_line_1() to use them;
 463         modify find_function_start_sal() to account for overlay sections;
 464         add macro INIT_SAL() for initializing struct symtab_and_line.
 465         * target.c: fix a comment in the declaration of target_ops.

 475         (mips_frame_chain): Skip over MIPS16 thunks.
 476         * config/mips/tm-mips.h (mips_in_call_stub, mips_in_return_stub,
