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

 255         serial_send_break serial_close):  Merge common functionality into
 256         serial_logchar.  Clean up rest of routines.
 257         * sparclet-rom.c:  Disembowel.  Leave only download routine.
 258         Download routine now switches to remote target automatically.
 259         * top.c (disconnect):  Only define if SIGHUP is defined.  Cleans

 262         or gdb_stderr.
 263         * config/sh/tm-sh.h:  Define TARGET_SH for WinGDB.

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

 335
 336 Mon Apr 14 16:25:10 1997  Ian Lance Taylor  <ian@cygnus.com>
 337

 341 Mon Apr 14 11:55:27 1997  Geoffrey Noer  <noer@pizza.cygnus.com>
 342
 343         * config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
 344         since gcc automatically includes it
 345
 346 Thu Apr 10 13:20:53 1997  Geoffrey Noer  <noer@cygnus.com>
 347
 348         * procfs.c: Substantial (but incomplete) changes to support
 349         sysv4.2mp procfs as implemented in UnixWare 2.1.  The procinfo
 350         struct now has substructs like struct flt_ctl instead of
 351         just a fltset_t and has a ctl_fd, status_fd, as_fd, and
 352         map_fd instead of a single fd.  Non-sysv4.2mp procfs models
 353         still have the structs and multiple fds, but don't use the
 354         entire struct and the four fds all point to the same thing.
 355         We use PROCFS_USE_READ_WRITE to decide whether to talk to
 356         procfs with reads/writes or use ioctl instead.  We use
 357         HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
 358         multiple fds or not.  PROC_NAME_FMT is split out into
 359         CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
 360         STATUS_PROC_NAME_FMT.
 361
 362         (procfs_notice_signals): now a necessary wrapper around
 363         (notice_signals): which are the new guts for noticing signals
 364         (open_proc_file): gets a new flag arg used in sysv4.2mp to
 365         determine whether or not to attempt to open the ctl_fd.
 366         (procfs_read_status): new local function, reads procfs status
 367         (procfs_write_pcwstop): new local function, writes a PCWSTOP
 368         (procfs_write_pckill): new local function, writes a PCKILL
 369         (unconditionally_kill_inferior): remove signo since we now
 370         just call procfs_write_pckill().
 371         (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
 372         (proc_iterate_over_mappings): the whole function is ifdefed
 373         on UNIXWARE to keep things readable.
 374
 375         Expanded the syscall_table to include new potential sysv4.2mp
 376         members.  Note that all ifdefs of UNIXWARE should be eliminated
 377         if possible or renamed to describe what's being selected for a
 378         bit better.  Sysv4.2mp and IRIX both have SYS_sproc so the
 379         IRIX specific code now also checks it's not UNIXWARE.
 380
 381         * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
 382         HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
 383         * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
 384         "/debug/%d" as PROC_NAME_FMT used to be
 385
 386 Wed Apr  9 11:36:14 1997  Jeffrey A Law  (law@cygnus.com)
 387
 388         * mn10300-tdep.c: Almost completely rewritten based on mn10200
 389         port.
 390         * config/mn10300/tm-mn10300.h: Likewise.
 391
 392 Tue Apr  8 10:45:24 1997  Stu Grossman  (grossman@critters.cygnus.com)
 393
 394         * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}:  Remove
 395         remote-pa.o from TDEPFILES.  Nobody uses it, and besides, it's a
 396         lousy out-of-date clone of remote.c.
 397
 398 Fri Apr  4 08:21:21 1997  Stu Grossman  (grossman@critters.cygnus.com)
 399
 400         * remote.c:  Fix problems realized while showering.
 401         * (hexnumlen):  Add prototype.  Use max, not min.
 402         * (remote_write_bytes remote_read_bytes):  Fix max packet size
 403         calculations to properly account for packet overhead.  Also handle
 404         (probably rare) case where remote_register_buf_size isn't set.
 405
 406         * remote.c:  Fix doc for `C' and `S' commands to indicate full
 407         address.
 408         * (remote_ops extended_remote_ops remote_desc remote_write_size):
 409         Make static.
 410         * (remote_fetch_registers remote_write_bytes remote_read_bytes):
 411         Record size of response to fetch registers command, use this to
 412         limit size of memory read and write commands.
 413         * (push_remote_target):  New function to make it possible to have
 414         another target switch to the remote target.
 415         * target.h:  Add prototype for push_remote_target.
 416         * sh-tdep.c (sh_frame_find_saved_regs):  Fix sign extension bugs
 417         for hosts which default to unsigned chars (such as SGI's).
 418         * (_initialize_sh_tdep):  Don't set remote_write_size.  It's now
 419         handled automatically in remote.c.

 421 Thu Apr  3 15:10:30 1997  Michael Snyder  <msnyder@cleaver.cygnus.com>
 422
 423         * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
 424         find_pc_sect_function(), find_pc_sect_partial_function(): new
 425         functions for debugging overlays; pc without section is ambiguous.
 426         * breakpoint.[ch]: add section pointer to breakpoint struct;
 427         add section argument to check_duplicates(); check section as well
 428         as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
 429         breakpoint_thread_match(), bpstat_stop_status()];
 430         add section argument to describe_other_breakpoints();
 431         use INIT_SAL() macro to zero-out new sal structures;
 432         make resolve_sal_pc() fix up the sal's section as well as its pc;
 433         match on section + pc in clear_command() and delete_breakpoint();
 434         account for overlay sections in insert_breakpoints(),
 435         remove_breakpoint() and breakpoint_re_set_one();
 436         all this to support overlays where a PC is not unique.
 437         * exec.c: change xfer_memory() to handle overlay sections.
 438         * findvar.c: change read_var_value() to handle overlay sections.
 439         * frame.h: declaration for block_for_pc_sect() [blockframe.c].
 440         * infcmd.c: jump_command() warns against jumping into an overlay
 441         that's not in memory.  Also use INIT_SAL() to initialize sals.
 442         * infrun.c: wait_for_inferior() sets a flag to invalidate cached
 443         overlay state information; Also use INIT_SAL() to init sals.
 444         * m32r-rom.c: modify load routines to use LMA instead of VMA.
 445         * m32r-stub.c: mask exit value down to 8 bits; screen out any
 446         memory read/writes in the range 600000 to a00000, and ff680000
 447         to ff800000 (hangs because nothing is mapped there); fix strcpy().
 448         * maint.c: maintenance command "translate-address" supports overlays.
 449         * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
 450         * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
 451         this constitutes gdb's internal overlay mapping table.  Add macro
 452         ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
 453         Add function find_pc_sect_section().
 454         * printcmd.c: modify print_address_symbolic() with overlay smarts;
 455         modify address_info() with overlay smarts; add function sym_info()
 456         to support the INFO SYMBOL command (translate address to symbol(s));
 457         modify disassemble_command() to work on unmapped overlays.
 458         * source.c: use INIT_SAL() to initialize sals.
 459         * symfile.[ch]: change generic_load() to use section's LMA address
 460         instead of VMA address, for overlay sections.
 461         Add numerous functions for finding a PC's section / overlay,
 462         translating between VMA and LMA address ranges, determining if an
 463         overlay section is mapped, etc.  Add several user commands for
 464         overlay debugging.  Add support for a "generic" form of automatically
 465         reading overlay mapping info from the inferior (based on the default
 466         (simple) overlay manager which Cygnus provides as an example).
 467         * symtab.[ch]: add functions find_pc_sect_symtab(),
 468         find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
 469         for lookup; modify lookup_symbol and decode_line_1() to use them;
 470         modify find_function_start_sal() to account for overlay sections;
 471         add macro INIT_SAL() for initializing struct symtab_and_line.
 472         * target.c: fix a comment in the declaration of target_ops.

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