 399         * Makefile.in (SUBDIRS):  Add mswin so that make cleanup cleans up
 400         that directory.
 401         * defs.h utils.c (error warning):  Make message be const.
 402         * main.c (fputs_unfiltered):  Only send gdb_stdout and gdb_stderr
 403         to hook.  Otherwise send it to fputs.
 404         * monitor.c monitor.h (monitor_get_dev_name):  New function.  Does
 405         the obvious.
 406         * remote-e7000.c:  Remove debugify stuff.  Change printf, fprintf
 407         to _filtered forms to make output appear in GUIs.  Replace all
 408         uses of SERIAL_READCHAR with readchar, which has better error
 409         checking.
 410         * (e7000_parse_device):  Add prototype.
 411         (readchar):  Improve doc.  Handle random serial errors.
 412         (expect):  Disable notice_quit code.  It's busted.  Remove
 413         serial error handling (it's now handled in readchar).  Remove

 415         (e7000_parse_device):  Remove serial_flag arg.  It's not
 416         necessary.
 417         (e7000_open):  Split into two pieces.  Second part is
 418         e7000_start_remote, and is error protected.  Now, when we connect
 419         to the target, we setup the initial frame and registers so that
 420         the user gets an immediate indication of where the target is.
 421         (gch):  Remove debug output.  That's handled by readchar.
 422         (e7000_read_inferior_memory):  Handle errors better.
 423         (_initialize_remote_e7000):  Get rid of `<xxx>' things from
 424         command names.  They show up when doing completion and confuse
 425         things horribly.
 426         * ser-e7kpc.c: Get rid of the DLL's since we can access the device
 427         directly from Win32s and Win95.  Get rid of debugify crud.
 428         * serial.c:  Remove debugify cruft.
 429         * (serial_logchar serial_log_command serial_write serial_readchar
 430         serial_send_break serial_close):  Merge common functionality into
 431         serial_logchar.  Clean up rest of routines.
 432         * sparclet-rom.c:  Disembowel.  Leave only download routine.
 433         Download routine now switches to remote target automatically.
 434         * top.c (disconnect):  Only define if SIGHUP is defined.  Cleans
 435         up MSVC/Win32 problem.
 436         * utils.c (gdb_flush):  Don't call hook unless it's for gdb_stdout
 437         or gdb_stderr.
 438         * config/sh/tm-sh.h:  Define TARGET_SH for WinGDB.
 439         * config/sparc/tm-sparclet.h:  Remove override for prompt.

 451         operations.
 452         (gdbsim_wait, gdbsim_resume): Move call to sim_resume into
 453         sim_wait where gdb is in a position to handle a long running
 454         function.
 455         (gdbsim_cntrl_c): New function.  Wrap the sim_resume call in a
 456         SIGINT handler.
 457         (gdb_os_poll_quit): New function. Check for a quit pending on the
 458         console.

 520
 521 Thu Apr 10 13:20:53 1997  Geoffrey Noer  <noer@cygnus.com>
 522
 523         * procfs.c: Substantial (but incomplete) changes to support
 524         sysv4.2mp procfs as implemented in UnixWare 2.1.  The procinfo
 525         struct now has substructs like struct flt_ctl instead of
 526         just a fltset_t and has a ctl_fd, status_fd, as_fd, and
 527         map_fd instead of a single fd.  Non-sysv4.2mp procfs models
 528         still have the structs and multiple fds, but don't use the
 529         entire struct and the four fds all point to the same thing.
 530         We use PROCFS_USE_READ_WRITE to decide whether to talk to
 531         procfs with reads/writes or use ioctl instead.  We use
 532         HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
 533         multiple fds or not.  PROC_NAME_FMT is split out into
 534         CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
 535         STATUS_PROC_NAME_FMT.
 536
 537         (procfs_notice_signals): now a necessary wrapper around
 538         (notice_signals): which are the new guts for noticing signals
 539         (open_proc_file): gets a new flag arg used in sysv4.2mp to
 540         determine whether or not to attempt to open the ctl_fd.
 541         (procfs_read_status): new local function, reads procfs status
 542         (procfs_write_pcwstop): new local function, writes a PCWSTOP
 543         (procfs_write_pckill): new local function, writes a PCKILL
 544         (unconditionally_kill_inferior): remove signo since we now
 545         just call procfs_write_pckill().
 546         (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
 547         (proc_iterate_over_mappings): the whole function is ifdefed
 548         on UNIXWARE to keep things readable.
 549
 550         Expanded the syscall_table to include new potential sysv4.2mp
 551         members.  Note that all ifdefs of UNIXWARE should be eliminated
 552         if possible or renamed to describe what's being selected for a
 553         bit better.  Sysv4.2mp and IRIX both have SYS_sproc so the
 554         IRIX specific code now also checks it's not UNIXWARE.
 555
 556         * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
 557         HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
 558         * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
 559         "/debug/%d" as PROC_NAME_FMT used to be
 560
 561 Wed Apr  9 11:36:14 1997  Jeffrey A Law  (law@cygnus.com)
 562
 563         * mn10300-tdep.c: Almost completely rewritten based on mn10200
 564         port.
 565         * config/mn10300/tm-mn10300.h: Likewise.

 567 Tue Apr  8 10:45:24 1997  Stu Grossman  (grossman@critters.cygnus.com)
 568
 569         * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}:  Remove
 570         remote-pa.o from TDEPFILES.  Nobody uses it, and besides, it's a
 571         lousy out-of-date clone of remote.c.

 573 Fri Apr  4 08:21:21 1997  Stu Grossman  (grossman@critters.cygnus.com)
 574

 576         * (hexnumlen):  Add prototype.  Use max, not min.
 577         * (remote_write_bytes remote_read_bytes):  Fix max packet size
 578         calculations to properly account for packet overhead.  Also handle
 579         (probably rare) case where remote_register_buf_size isn't set.
 580
 581         * remote.c:  Fix doc for `C' and `S' commands to indicate full
 582         address.
 583         * (remote_ops extended_remote_ops remote_desc remote_write_size):
 584         Make static.
 585         * (remote_fetch_registers remote_write_bytes remote_read_bytes):
 586         Record size of response to fetch registers command, use this to
 587         limit size of memory read and write commands.
 588         * (push_remote_target):  New function to make it possible to have
 589         another target switch to the remote target.
 590         * target.h:  Add prototype for push_remote_target.
 591         * sh-tdep.c (sh_frame_find_saved_regs):  Fix sign extension bugs
 592         for hosts which default to unsigned chars (such as SGI's).
 593         * (_initialize_sh_tdep):  Don't set remote_write_size.  It's now
 594         handled automatically in remote.c.

 596 Thu Apr  3 15:10:30 1997  Michael Snyder  <msnyder@cleaver.cygnus.com>
 597
 598         * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
 599         find_pc_sect_function(), find_pc_sect_partial_function(): new
 600         functions for debugging overlays; pc without section is ambiguous.
 601         * breakpoint.[ch]: add section pointer to breakpoint struct;
 602         add section argument to check_duplicates(); check section as well
 603         as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
 604         breakpoint_thread_match(), bpstat_stop_status()];
 605         add section argument to describe_other_breakpoints();
 606         use INIT_SAL() macro to zero-out new sal structures;
 607         make resolve_sal_pc() fix up the sal's section as well as its pc;
 608         match on section + pc in clear_command() and delete_breakpoint();
 609         account for overlay sections in insert_breakpoints(),
 610         remove_breakpoint() and breakpoint_re_set_one();
 611         all this to support overlays where a PC is not unique.
 612         * exec.c: change xfer_memory() to handle overlay sections.
 613         * findvar.c: change read_var_value() to handle overlay sections.
 614         * frame.h: declaration for block_for_pc_sect() [blockframe.c].
 615         * infcmd.c: jump_command() warns against jumping into an overlay
 616         that's not in memory.  Also use INIT_SAL() to initialize sals.
 617         * infrun.c: wait_for_inferior() sets a flag to invalidate cached
 618         overlay state information; Also use INIT_SAL() to init sals.
 619         * m32r-rom.c: modify load routines to use LMA instead of VMA.
 620         * m32r-stub.c: mask exit value down to 8 bits; screen out any
 621         memory read/writes in the range 600000 to a00000, and ff680000
 622         to ff800000 (hangs because nothing is mapped there); fix strcpy().
 623         * maint.c: maintenance command "translate-address" supports overlays.
 624         * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
 625         * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
 626         this constitutes gdb's internal overlay mapping table.  Add macro
 627         ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
 628         Add function find_pc_sect_section().
 629         * printcmd.c: modify print_address_symbolic() with overlay smarts;
 630         modify address_info() with overlay smarts; add function sym_info()
 631         to support the INFO SYMBOL command (translate address to symbol(s));
 632         modify disassemble_command() to work on unmapped overlays.
 633         * source.c: use INIT_SAL() to initialize sals.
 634         * symfile.[ch]: change generic_load() to use section's LMA address
 635         instead of VMA address, for overlay sections.
 636         Add numerous functions for finding a PC's section / overlay,
 637         translating between VMA and LMA address ranges, determining if an
 638         overlay section is mapped, etc.  Add several user commands for
 639         overlay debugging.  Add support for a "generic" form of automatically
 640         reading overlay mapping info from the inferior (based on the default
 641         (simple) overlay manager which Cygnus provides as an example).
 642         * symtab.[ch]: add functions find_pc_sect_symtab(),
 643         find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
 644         for lookup; modify lookup_symbol and decode_line_1() to use them;
 645         modify find_function_start_sal() to account for overlay sections;
 646         add macro INIT_SAL() for initializing struct symtab_and_line.
 647         * target.c: fix a comment in the declaration of target_ops.
