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

 264         Download routine now switches to remote target automatically.
 265         * top.c (disconnect):  Only define if SIGHUP is defined.  Cleans

 268         or gdb_stderr.
 269         * config/sh/tm-sh.h:  Define TARGET_SH for WinGDB.

 282         operations.
 283         (gdbsim_wait, gdbsim_resume): Move call to sim_resume into
 284         sim_wait where gdb is in a position to handle a long running
 285         function.
 286         (gdbsim_cntrl_c): New function.  Wrap the sim_resume call in a
 287         SIGINT handler.

 348
 349         * config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
 350         since gcc automatically includes it
 351
 352 Thu Apr 10 13:20:53 1997  Geoffrey Noer  <noer@cygnus.com>
 353
 354         * procfs.c: Substantial (but incomplete) changes to support
 355         sysv4.2mp procfs as implemented in UnixWare 2.1.  The procinfo
 356         struct now has substructs like struct flt_ctl instead of
 357         just a fltset_t and has a ctl_fd, status_fd, as_fd, and
 358         map_fd instead of a single fd.  Non-sysv4.2mp procfs models
 359         still have the structs and multiple fds, but don't use the
 360         entire struct and the four fds all point to the same thing.
 361         We use PROCFS_USE_READ_WRITE to decide whether to talk to
 362         procfs with reads/writes or use ioctl instead.  We use
 363         HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
 364         multiple fds or not.  PROC_NAME_FMT is split out into
 365         CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
 366         STATUS_PROC_NAME_FMT.
 367
 368         (procfs_notice_signals): now a necessary wrapper around
 369         (notice_signals): which are the new guts for noticing signals
 370         (open_proc_file): gets a new flag arg used in sysv4.2mp to
 371         determine whether or not to attempt to open the ctl_fd.
 372         (procfs_read_status): new local function, reads procfs status
 373         (procfs_write_pcwstop): new local function, writes a PCWSTOP
 374         (procfs_write_pckill): new local function, writes a PCKILL
 375         (unconditionally_kill_inferior): remove signo since we now
 376         just call procfs_write_pckill().
 377         (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
 378         (proc_iterate_over_mappings): the whole function is ifdefed
 379         on UNIXWARE to keep things readable.
 380
 381         Expanded the syscall_table to include new potential sysv4.2mp
 382         members.  Note that all ifdefs of UNIXWARE should be eliminated
 383         if possible or renamed to describe what's being selected for a
 384         bit better.  Sysv4.2mp and IRIX both have SYS_sproc so the
 385         IRIX specific code now also checks it's not UNIXWARE.
 386
 387         * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
 388         HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
 389         * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
 390         "/debug/%d" as PROC_NAME_FMT used to be
 391
 392 Wed Apr  9 11:36:14 1997  Jeffrey A Law  (law@cygnus.com)
 393
 394         * mn10300-tdep.c: Almost completely rewritten based on mn10200
 395         port.
 396         * config/mn10300/tm-mn10300.h: Likewise.

 398 Tue Apr  8 10:45:24 1997  Stu Grossman  (grossman@critters.cygnus.com)
 399
 400         * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}:  Remove
 401         remote-pa.o from TDEPFILES.  Nobody uses it, and besides, it's a
 402         lousy out-of-date clone of remote.c.
 403
 404 Fri Apr  4 08:21:21 1997  Stu Grossman  (grossman@critters.cygnus.com)
 405
 406         * remote.c:  Fix problems realized while showering.
 407         * (hexnumlen):  Add prototype.  Use max, not min.
 408         * (remote_write_bytes remote_read_bytes):  Fix max packet size
 409         calculations to properly account for packet overhead.  Also handle
 410         (probably rare) case where remote_register_buf_size isn't set.
 411
 412         * remote.c:  Fix doc for `C' and `S' commands to indicate full
 413         address.
 414         * (remote_ops extended_remote_ops remote_desc remote_write_size):
 415         Make static.
 416         * (remote_fetch_registers remote_write_bytes remote_read_bytes):
 417         Record size of response to fetch registers command, use this to
 418         limit size of memory read and write commands.
 419         * (push_remote_target):  New function to make it possible to have
 420         another target switch to the remote target.
 421         * target.h:  Add prototype for push_remote_target.
 422         * sh-tdep.c (sh_frame_find_saved_regs):  Fix sign extension bugs
 423         for hosts which default to unsigned chars (such as SGI's).
 424         * (_initialize_sh_tdep):  Don't set remote_write_size.  It's now
 425         handled automatically in remote.c.

 427 Thu Apr  3 15:10:30 1997  Michael Snyder  <msnyder@cleaver.cygnus.com>
 428
 429         * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
 430         find_pc_sect_function(), find_pc_sect_partial_function(): new
 431         functions for debugging overlays; pc without section is ambiguous.
 432         * breakpoint.[ch]: add section pointer to breakpoint struct;
 433         add section argument to check_duplicates(); check section as well
 434         as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
 435         breakpoint_thread_match(), bpstat_stop_status()];
 436         add section argument to describe_other_breakpoints();
 437         use INIT_SAL() macro to zero-out new sal structures;
 438         make resolve_sal_pc() fix up the sal's section as well as its pc;
 439         match on section + pc in clear_command() and delete_breakpoint();
 440         account for overlay sections in insert_breakpoints(),
 441         remove_breakpoint() and breakpoint_re_set_one();
 442         all this to support overlays where a PC is not unique.
 443         * exec.c: change xfer_memory() to handle overlay sections.
 444         * findvar.c: change read_var_value() to handle overlay sections.
 445         * frame.h: declaration for block_for_pc_sect() [blockframe.c].
 446         * infcmd.c: jump_command() warns against jumping into an overlay
 447         that's not in memory.  Also use INIT_SAL() to initialize sals.
 448         * infrun.c: wait_for_inferior() sets a flag to invalidate cached
 449         overlay state information; Also use INIT_SAL() to init sals.
 450         * m32r-rom.c: modify load routines to use LMA instead of VMA.
 451         * m32r-stub.c: mask exit value down to 8 bits; screen out any
 452         memory read/writes in the range 600000 to a00000, and ff680000
 453         to ff800000 (hangs because nothing is mapped there); fix strcpy().
 454         * maint.c: maintenance command "translate-address" supports overlays.
 455         * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
 456         * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
 457         this constitutes gdb's internal overlay mapping table.  Add macro
 458         ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
 459         Add function find_pc_sect_section().
 460         * printcmd.c: modify print_address_symbolic() with overlay smarts;
 461         modify address_info() with overlay smarts; add function sym_info()
 462         to support the INFO SYMBOL command (translate address to symbol(s));
 463         modify disassemble_command() to work on unmapped overlays.
 464         * source.c: use INIT_SAL() to initialize sals.
 465         * symfile.[ch]: change generic_load() to use section's LMA address
 466         instead of VMA address, for overlay sections.
 467         Add numerous functions for finding a PC's section / overlay,
 468         translating between VMA and LMA address ranges, determining if an
 469         overlay section is mapped, etc.  Add several user commands for
 470         overlay debugging.  Add support for a "generic" form of automatically
 471         reading overlay mapping info from the inferior (based on the default
 472         (simple) overlay manager which Cygnus provides as an example).
 473         * symtab.[ch]: add functions find_pc_sect_symtab(),
 474         find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
 475         for lookup; modify lookup_symbol and decode_line_1() to use them;
 476         modify find_function_start_sal() to account for overlay sections;
 477         add macro INIT_SAL() for initializing struct symtab_and_line.
 478         * target.c: fix a comment in the declaration of target_ops.

 487         new code to skip over MIPS16 thunks.
 488         (mips_frame_chain): Skip over MIPS16 thunks.
 489         * config/mips/tm-mips.h (mips_in_call_stub, mips_in_return_stub,
