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

 274         Download routine now switches to remote target automatically.

 278         or gdb_stderr.
 279         * config/sh/tm-sh.h:  Define TARGET_SH for WinGDB.

 292         operations.
 293         (gdbsim_wait, gdbsim_resume): Move call to sim_resume into
 294         sim_wait where gdb is in a position to handle a long running
 295         function.
 296         (gdbsim_cntrl_c): New function.  Wrap the sim_resume call in a
 297         SIGINT handler.

 338         (INSTALL_XFORM1): Remove.
 339         (install-only): Use $(program_transform_name) directly, rather
 340         than using $(INSTALL_XFORM) and $(INSTALL_XFORM1).

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

 497         new code to skip over MIPS16 thunks.
 498         (mips_frame_chain): Skip over MIPS16 thunks.
 499         * config/mips/tm-mips.h (mips_in_call_stub, mips_in_return_stub,
