        necessary.
        (e7000_open):  Split into two pieces.  Second part is
        e7000_start_remote, and is error protected.  Now, when we connect

        since gcc automatically includes it

Thu Apr 10 13:20:53 1997  Geoffrey Noer  <noer@cygnus.com>

        * procfs.c: Substantial (but incomplete) changes to support
        sysv4.2mp procfs as implemented in UnixWare 2.1.  The procinfo
        struct now has substructs like struct flt_ctl instead of
        just a fltset_t and has a ctl_fd, status_fd, as_fd, and
        map_fd instead of a single fd.  Non-sysv4.2mp procfs models
        still have the structs and multiple fds, but don't use the
        entire struct and the four fds all point to the same thing.
        We use PROCFS_USE_READ_WRITE to decide whether to talk to
        procfs with reads/writes or use ioctl instead.  We use
        HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
        multiple fds or not.  PROC_NAME_FMT is split out into
        CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT, 
        STATUS_PROC_NAME_FMT.
        
        (procfs_notice_signals): now a necessary wrapper around
        (notice_signals): which are the new guts for noticing signals
        (open_proc_file): gets a new flag arg used in sysv4.2mp to
        determine whether or not to attempt to open the ctl_fd.
        (procfs_read_status): new local function, reads procfs status
        (procfs_write_pcwstop): new local function, writes a PCWSTOP
        (procfs_write_pckill): new local function, writes a PCKILL
        (unconditionally_kill_inferior): remove signo since we now
        just call procfs_write_pckill().
        (procfs_xfer_memory): call lseek with SEEK_SET rather than 0    
        (proc_iterate_over_mappings): the whole function is ifdefed
        on UNIXWARE to keep things readable.
        
        Expanded the syscall_table to include new potential sysv4.2mp
        members.  Note that all ifdefs of UNIXWARE should be eliminated
        if possible or renamed to describe what's being selected for a
        bit better.  Sysv4.2mp and IRIX both have SYS_sproc so the
        IRIX specific code now also checks it's not UNIXWARE.

        * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
        HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
        * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
        "/debug/%d" as PROC_NAME_FMT used to be

Wed Apr  9 11:36:14 1997  Jeffrey A Law  (law@cygnus.com)

        * mn10300-tdep.c: Almost completely rewritten based on mn10200
        port.

Tue Apr  8 10:45:24 1997  Stu Grossman  (grossman@critters.cygnus.com)

        * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}:  Remove
        remote-pa.o from TDEPFILES.  Nobody uses it, and besides, it's a
        lousy out-of-date clone of remote.c.

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

        * remote.c:  Fix problems realized while showering.
        * (hexnumlen):  Add prototype.  Use max, not min.
        * (remote_write_bytes remote_read_bytes):  Fix max packet size
        calculations to properly account for packet overhead.  Also handle
        (probably rare) case where remote_register_buf_size isn't set.

        * remote.c:  Fix doc for `C' and `S' commands to indicate full
        address.
        * (remote_ops extended_remote_ops remote_desc remote_write_size):
        Make static.
        * (remote_fetch_registers remote_write_bytes remote_read_bytes):
        Record size of response to fetch registers command, use this to
        limit size of memory read and write commands.
        * (push_remote_target):  New function to make it possible to have
        another target switch to the remote target.
        * target.h:  Add prototype for push_remote_target.
        * sh-tdep.c (sh_frame_find_saved_regs):  Fix sign extension bugs
        for hosts which default to unsigned chars (such as SGI's).
        * (_initialize_sh_tdep):  Don't set remote_write_size.  It's now
        handled automatically in remote.c.

Thu Apr  3 15:10:30 1997  Michael Snyder  <msnyder@cleaver.cygnus.com>

        * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(), 
        find_pc_sect_function(), find_pc_sect_partial_function(): new 
        functions for debugging overlays; pc without section is ambiguous.
        * breakpoint.[ch]: add section pointer to breakpoint struct;
        add section argument to check_duplicates(); check section as well
        as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
        breakpoint_thread_match(), bpstat_stop_status()];  
        add section argument to describe_other_breakpoints(); 
        use INIT_SAL() macro to zero-out new sal structures; 
        make resolve_sal_pc() fix up the sal's section as well as its pc; 
        match on section + pc in clear_command() and delete_breakpoint(); 
        account for overlay sections in insert_breakpoints(), 
        remove_breakpoint() and breakpoint_re_set_one();
        all this to support overlays where a PC is not unique.
        * exec.c: change xfer_memory() to handle overlay sections.
        * findvar.c: change read_var_value() to handle overlay sections.
        * frame.h: declaration for block_for_pc_sect() [blockframe.c].
        * infcmd.c: jump_command() warns against jumping into an overlay
        that's not in memory.  Also use INIT_SAL() to initialize sals.
        * infrun.c: wait_for_inferior() sets a flag to invalidate cached
        overlay state information; Also use INIT_SAL() to init sals.
        * m32r-rom.c: modify load routines to use LMA instead of VMA.
        * m32r-stub.c: mask exit value down to 8 bits; screen out any
        memory read/writes in the range 600000 to a00000, and ff680000
        to ff800000 (hangs because nothing is mapped there); fix strcpy().
        * maint.c: maintenance command "translate-address" supports overlays.
        * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
        * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
        this constitutes gdb's internal overlay mapping table.  Add macro
        ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
        Add function find_pc_sect_section().
        * printcmd.c: modify print_address_symbolic() with overlay smarts;
        modify address_info() with overlay smarts; add function sym_info() 
        to support the INFO SYMBOL command (translate address to symbol(s));
        modify disassemble_command() to work on unmapped overlays.
        * source.c: use INIT_SAL() to initialize sals.
        * symfile.[ch]: change generic_load() to use section's LMA address
        instead of VMA address, for overlay sections.
        Add numerous functions for finding a PC's section / overlay, 
        translating between VMA and LMA address ranges, determining if an
        overlay section is mapped, etc.  Add several user commands for
        overlay debugging.  Add support for a "generic" form of automatically
        reading overlay mapping info from the inferior (based on the default
        (simple) overlay manager which Cygnus provides as an example).
        * symtab.[ch]: add functions find_pc_sect_symtab(), 
        find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
        for lookup; modify lookup_symbol and decode_line_1() to use them;
        modify find_function_start_sal() to account for overlay sections;
        add macro INIT_SAL() for initializing struct symtab_and_line.
        * target.c: fix a comment in the declaration of target_ops.

Thu Apr  3 10:31:12 1997  Mark Alexander  <marka@cygnus.com>
