 668         just a fltset_t and has a ctl_fd, status_fd, as_fd, and
 669         map_fd instead of a single fd.  Non-sysv4.2mp procfs models
 670         still have the structs and multiple fds, but don't use the
 671         entire struct and the four fds all point to the same thing.
 672         We use PROCFS_USE_READ_WRITE to decide whether to talk to
 673         procfs with reads/writes or use ioctl instead.  We use
 674         HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
 675         multiple fds or not.  PROC_NAME_FMT is split out into
 676         CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
 677         STATUS_PROC_NAME_FMT.
 678
 679         (procfs_notice_signals): now a necessary wrapper around
 680         (notice_signals): which are the new guts for noticing signals
 681         (open_proc_file): gets a new flag arg used in sysv4.2mp to
 682         determine whether or not to attempt to open the ctl_fd.
 683         (procfs_read_status): new local function, reads procfs status
 684         (procfs_write_pcwstop): new local function, writes a PCWSTOP
 685         (procfs_write_pckill): new local function, writes a PCKILL
 686         (unconditionally_kill_inferior): remove signo since we now
 687         just call procfs_write_pckill().
 688         (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
 689         (proc_iterate_over_mappings): the whole function is ifdefed
 690         on UNIXWARE to keep things readable.
 691
 692         Expanded the syscall_table to include new potential sysv4.2mp
 693         members.  Note that all ifdefs of UNIXWARE should be eliminated
 694         if possible or renamed to describe what's being selected for a
 695         bit better.  Sysv4.2mp and IRIX both have SYS_sproc so the
 696         IRIX specific code now also checks it's not UNIXWARE.
 697
 698         * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
 699         HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
 700         * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
 701         "/debug/%d" as PROC_NAME_FMT used to be

 704
 705         * mn10300-tdep.c: Almost completely rewritten based on mn10200
 706         port.

 710
 711         * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}:  Remove
 712         remote-pa.o from TDEPFILES.  Nobody uses it, and besides, it's a
 713         lousy out-of-date clone of remote.c.

 715 Fri Apr  4 08:21:21 1997  Stu Grossman  (grossman@critters.cygnus.com)
 716

 718         * (hexnumlen):  Add prototype.  Use max, not min.
 719         * (remote_write_bytes remote_read_bytes):  Fix max packet size
 720         calculations to properly account for packet overhead.  Also handle
 721         (probably rare) case where remote_register_buf_size isn't set.
 722
 723         * remote.c:  Fix doc for `C' and `S' commands to indicate full
 724         address.

 726         Make static.
 727         * (remote_fetch_registers remote_write_bytes remote_read_bytes):
 728         Record size of response to fetch registers command, use this to
 729         limit size of memory read and write commands.
 730         * (push_remote_target):  New function to make it possible to have
 731         another target switch to the remote target.
 732         * target.h:  Add prototype for push_remote_target.
 733         * sh-tdep.c (sh_frame_find_saved_regs):  Fix sign extension bugs
 734         for hosts which default to unsigned chars (such as SGI's).
 735         * (_initialize_sh_tdep):  Don't set remote_write_size.  It's now
 736         handled automatically in remote.c.

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

 799         (mips_frame_chain): Skip over MIPS16 thunks.
 800         * config/mips/tm-mips.h (mips_in_call_stub, mips_in_return_stub,

1640         * mn10300-tdep.c (mn10300_push_arguments): rewrote,
1641         also removed code elsewhere that made use of RP_REGNUM.
1642         * config/mn10300/tm-mn10300.h: ripped out RP_REGNUM, V0_REGNUM,
1643         ARG0_REGNUM, ARGLAST_REGNUM (all not appropriate for mn10300
1644         arch.), redefined SAVED_PC_AFTER_CALL, EXTRACT_RETURN_VALUE,
1645         EXTRACT_STRUCT_VALUE_ADDRESS, STORE_RETURN_VALUE.
