 336         satisfy symbol dependancy in solib.c (core_ops).
 337         * target.[ch] conditionalize Mach-specific signals so that they
 338         won't show up in non-Mach gdb's!
 339         * thread.c: change name of static function "thread_switch" to
 340         "switch_to_thread", to avoid conflict with Mach global symbol;
 341         move thread_cmd_list to global scope so targets can add their
 342         own thread commands.
 343         * infrun.c: sig_print_info: allow for long signal names.
 344         * gnu-nat.[ch]: tidying up comments.
 345         * gnu-nat.c: remove calls to prune_threads and renumber_threads;
 346         gnu_wait must not return -1 when inferior exits;
 347         attach_to_child will modify inferior_pid in a way that allows
 348         fork_inferior to remain unchanged; remove extra arg from
 349         startup_inferior; move Mach thread commands here from thread.c.

 492         * main.c (fputs_unfiltered):  Only send gdb_stdout and gdb_stderr

 495         the obvious.
 496         * remote-e7000.c:  Remove debugify stuff.  Change printf, fprintf
 497         to _filtered forms to make output appear in GUIs.  Replace all
 498         uses of SERIAL_READCHAR with readchar, which has better error
 499         checking.
 500         * (e7000_parse_device):  Add prototype.
 501         (readchar):  Improve doc.  Handle random serial errors.

 506         necessary.
 507         (e7000_open):  Split into two pieces.  Second part is
 508         e7000_start_remote, and is error protected.  Now, when we connect
 509         to the target, we setup the initial frame and registers so that
 510         the user gets an immediate indication of where the target is.

 512         (e7000_read_inferior_memory):  Handle errors better.
 513         (_initialize_remote_e7000):  Get rid of `<xxx>' things from

 515         things horribly.
 516         * ser-e7kpc.c: Get rid of the DLL's since we can access the device
 517         directly from Win32s and Win95.  Get rid of debugify crud.

 522         * sparclet-rom.c:  Disembowel.  Leave only download routine.
 523         Download routine now switches to remote target automatically.
 524         * top.c (disconnect):  Only define if SIGHUP is defined.  Cleans
 525         up MSVC/Win32 problem.

 544         function.
 545         (gdbsim_cntrl_c): New function.  Wrap the sim_resume call in a

 611 Thu Apr 10 13:20:53 1997  Geoffrey Noer  <noer@cygnus.com>
 612
 613         * procfs.c: Substantial (but incomplete) changes to support
 614         sysv4.2mp procfs as implemented in UnixWare 2.1.  The procinfo
 615         struct now has substructs like struct flt_ctl instead of
 616         just a fltset_t and has a ctl_fd, status_fd, as_fd, and
 617         map_fd instead of a single fd.  Non-sysv4.2mp procfs models
 618         still have the structs and multiple fds, but don't use the
 619         entire struct and the four fds all point to the same thing.
 620         We use PROCFS_USE_READ_WRITE to decide whether to talk to
 621         procfs with reads/writes or use ioctl instead.  We use
 622         HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
 623         multiple fds or not.  PROC_NAME_FMT is split out into
 624         CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
 625         STATUS_PROC_NAME_FMT.
 626
 627         (procfs_notice_signals): now a necessary wrapper around
 628         (notice_signals): which are the new guts for noticing signals
 629         (open_proc_file): gets a new flag arg used in sysv4.2mp to
 630         determine whether or not to attempt to open the ctl_fd.
 631         (procfs_read_status): new local function, reads procfs status
 632         (procfs_write_pcwstop): new local function, writes a PCWSTOP
 633         (procfs_write_pckill): new local function, writes a PCKILL
 634         (unconditionally_kill_inferior): remove signo since we now
 635         just call procfs_write_pckill().
 636         (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
 637         (proc_iterate_over_mappings): the whole function is ifdefed
 638         on UNIXWARE to keep things readable.
 639
 640         Expanded the syscall_table to include new potential sysv4.2mp
 641         members.  Note that all ifdefs of UNIXWARE should be eliminated
 642         if possible or renamed to describe what's being selected for a
 643         bit better.  Sysv4.2mp and IRIX both have SYS_sproc so the
 644         IRIX specific code now also checks it's not UNIXWARE.
 645
 646         * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
 647         HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
 648         * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
 649         "/debug/%d" as PROC_NAME_FMT used to be

 664
 665         * remote.c:  Fix problems realized while showering.
 666         * (hexnumlen):  Add prototype.  Use max, not min.
 667         * (remote_write_bytes remote_read_bytes):  Fix max packet size
 668         calculations to properly account for packet overhead.  Also handle
 669         (probably rare) case where remote_register_buf_size isn't set.
 670
 671         * remote.c:  Fix doc for `C' and `S' commands to indicate full

 689         find_pc_sect_function(), find_pc_sect_partial_function(): new
 690         functions for debugging overlays; pc without section is ambiguous.
 691         * breakpoint.[ch]: add section pointer to breakpoint struct;
 692         add section argument to check_duplicates(); check section as well
 693         as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
 694         breakpoint_thread_match(), bpstat_stop_status()];
 695         add section argument to describe_other_breakpoints();
 696         use INIT_SAL() macro to zero-out new sal structures;
 697         make resolve_sal_pc() fix up the sal's section as well as its pc;
 698         match on section + pc in clear_command() and delete_breakpoint();
 699         account for overlay sections in insert_breakpoints(),
 700         remove_breakpoint() and breakpoint_re_set_one();
 701         all this to support overlays where a PC is not unique.
 702         * exec.c: change xfer_memory() to handle overlay sections.
 703         * findvar.c: change read_var_value() to handle overlay sections.
 704         * frame.h: declaration for block_for_pc_sect() [blockframe.c].
 705         * infcmd.c: jump_command() warns against jumping into an overlay
 706         that's not in memory.  Also use INIT_SAL() to initialize sals.
 707         * infrun.c: wait_for_inferior() sets a flag to invalidate cached
 708         overlay state information; Also use INIT_SAL() to init sals.

 710         * m32r-stub.c: mask exit value down to 8 bits; screen out any
 711         memory read/writes in the range 600000 to a00000, and ff680000
 712         to ff800000 (hangs because nothing is mapped there); fix strcpy().
 713         * maint.c: maintenance command "translate-address" supports overlays.
 714         * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
 715         * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
 716         this constitutes gdb's internal overlay mapping table.  Add macro
 717         ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
 718         Add function find_pc_sect_section().
 719         * printcmd.c: modify print_address_symbolic() with overlay smarts;
 720         modify address_info() with overlay smarts; add function sym_info()
 721         to support the INFO SYMBOL command (translate address to symbol(s));
 722         modify disassemble_command() to work on unmapped overlays.
 723         * source.c: use INIT_SAL() to initialize sals.
 724         * symfile.[ch]: change generic_load() to use section's LMA address
 725         instead of VMA address, for overlay sections.
 726         Add numerous functions for finding a PC's section / overlay,
 727         translating between VMA and LMA address ranges, determining if an
 728         overlay section is mapped, etc.  Add several user commands for
 729         overlay debugging.  Add support for a "generic" form of automatically
 730         reading overlay mapping info from the inferior (based on the default
 731         (simple) overlay manager which Cygnus provides as an example).
 732         * symtab.[ch]: add functions find_pc_sect_symtab(),
 733         find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
 734         for lookup; modify lookup_symbol and decode_line_1() to use them;
 735         modify find_function_start_sal() to account for overlay sections;
 736         add macro INIT_SAL() for initializing struct symtab_and_line.
 737         * target.c: fix a comment in the declaration of target_ops.
