 687
 688 Mon Apr 14 16:25:10 1997  Ian Lance Taylor  <ian@cygnus.com>
 689

 693 Mon Apr 14 11:55:27 1997  Geoffrey Noer  <noer@pizza.cygnus.com>
 694
 695         * config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
 696         since gcc automatically includes it
 697
 698 Thu Apr 10 13:20:53 1997  Geoffrey Noer  <noer@cygnus.com>
 699
 700         * procfs.c: Substantial (but incomplete) changes to support
 701         sysv4.2mp procfs as implemented in UnixWare 2.1.  The procinfo
 702         struct now has substructs like struct flt_ctl instead of
 703         just a fltset_t and has a ctl_fd, status_fd, as_fd, and
 704         map_fd instead of a single fd.  Non-sysv4.2mp procfs models
 705         still have the structs and multiple fds, but don't use the
 706         entire struct and the four fds all point to the same thing.
 707         We use PROCFS_USE_READ_WRITE to decide whether to talk to
 708         procfs with reads/writes or use ioctl instead.  We use
 709         HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
 710         multiple fds or not.  PROC_NAME_FMT is split out into
 711         CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
 712         STATUS_PROC_NAME_FMT.
 713
 714         (procfs_notice_signals): now a necessary wrapper around
 715         (notice_signals): which are the new guts for noticing signals
 716         (open_proc_file): gets a new flag arg used in sysv4.2mp to
 717         determine whether or not to attempt to open the ctl_fd.
 718         (procfs_read_status): new local function, reads procfs status
 719         (procfs_write_pcwstop): new local function, writes a PCWSTOP
 720         (procfs_write_pckill): new local function, writes a PCKILL
 721         (unconditionally_kill_inferior): remove signo since we now
 722         just call procfs_write_pckill().
 723         (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
 724         (proc_iterate_over_mappings): the whole function is ifdefed
 725         on UNIXWARE to keep things readable.
 726
 727         Expanded the syscall_table to include new potential sysv4.2mp
 728         members.  Note that all ifdefs of UNIXWARE should be eliminated
 729         if possible or renamed to describe what's being selected for a
 730         bit better.  Sysv4.2mp and IRIX both have SYS_sproc so the
 731         IRIX specific code now also checks it's not UNIXWARE.
 732
 733         * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
 734         HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
 735         * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
 736         "/debug/%d" as PROC_NAME_FMT used to be
 737
 738 Wed Apr  9 11:36:14 1997  Jeffrey A Law  (law@cygnus.com)
 739
 740         * mn10300-tdep.c: Almost completely rewritten based on mn10200
 741         port.
 742         * config/mn10300/tm-mn10300.h: Likewise.
 743
 744 Tue Apr  8 10:45:24 1997  Stu Grossman  (grossman@critters.cygnus.com)
 745
 746         * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}:  Remove
 747         remote-pa.o from TDEPFILES.  Nobody uses it, and besides, it's a
 748         lousy out-of-date clone of remote.c.
 749
 750 Fri Apr  4 08:21:21 1997  Stu Grossman  (grossman@critters.cygnus.com)
 751
 752         * remote.c:  Fix problems realized while showering.
 753         * (hexnumlen):  Add prototype.  Use max, not min.
 754         * (remote_write_bytes remote_read_bytes):  Fix max packet size
 755         calculations to properly account for packet overhead.  Also handle
 756         (probably rare) case where remote_register_buf_size isn't set.
 757
 758         * remote.c:  Fix doc for `C' and `S' commands to indicate full
 759         address.
 760         * (remote_ops extended_remote_ops remote_desc remote_write_size):
 761         Make static.
 762         * (remote_fetch_registers remote_write_bytes remote_read_bytes):
 763         Record size of response to fetch registers command, use this to
 764         limit size of memory read and write commands.
 765         * (push_remote_target):  New function to make it possible to have
 766         another target switch to the remote target.
 767         * target.h:  Add prototype for push_remote_target.
 768         * sh-tdep.c (sh_frame_find_saved_regs):  Fix sign extension bugs
 769         for hosts which default to unsigned chars (such as SGI's).
 770         * (_initialize_sh_tdep):  Don't set remote_write_size.  It's now
 771         handled automatically in remote.c.
 772
 773 Thu Apr  3 15:10:30 1997  Michael Snyder  <msnyder@cleaver.cygnus.com>
 774
 775         * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
 776         find_pc_sect_function(), find_pc_sect_partial_function(): new
 777         functions for debugging overlays; pc without section is ambiguous.
 778         * breakpoint.[ch]: add section pointer to breakpoint struct;
 779         add section argument to check_duplicates(); check section as well
 780         as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
 781         breakpoint_thread_match(), bpstat_stop_status()];
 782         add section argument to describe_other_breakpoints();
 783         use INIT_SAL() macro to zero-out new sal structures;
 784         make resolve_sal_pc() fix up the sal's section as well as its pc;
 785         match on section + pc in clear_command() and delete_breakpoint();
 786         account for overlay sections in insert_breakpoints(),
 787         remove_breakpoint() and breakpoint_re_set_one();
 788         all this to support overlays where a PC is not unique.
 789         * exec.c: change xfer_memory() to handle overlay sections.
 790         * findvar.c: change read_var_value() to handle overlay sections.
 791         * frame.h: declaration for block_for_pc_sect() [blockframe.c].
 792         * infcmd.c: jump_command() warns against jumping into an overlay
 793         that's not in memory.  Also use INIT_SAL() to initialize sals.
 794         * infrun.c: wait_for_inferior() sets a flag to invalidate cached
 795         overlay state information; Also use INIT_SAL() to init sals.
 796         * m32r-rom.c: modify load routines to use LMA instead of VMA.
 797         * m32r-stub.c: mask exit value down to 8 bits; screen out any
 798         memory read/writes in the range 600000 to a00000, and ff680000
 799         to ff800000 (hangs because nothing is mapped there); fix strcpy().
 800         * maint.c: maintenance command "translate-address" supports overlays.
 801         * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
 802         * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
 803         this constitutes gdb's internal overlay mapping table.  Add macro
 804         ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
 805         Add function find_pc_sect_section().
 806         * printcmd.c: modify print_address_symbolic() with overlay smarts;
 807         modify address_info() with overlay smarts; add function sym_info()
 808         to support the INFO SYMBOL command (translate address to symbol(s));
 809         modify disassemble_command() to work on unmapped overlays.
 810         * source.c: use INIT_SAL() to initialize sals.
 811         * symfile.[ch]: change generic_load() to use section's LMA address
 812         instead of VMA address, for overlay sections.
 813         Add numerous functions for finding a PC's section / overlay,
 814         translating between VMA and LMA address ranges, determining if an
 815         overlay section is mapped, etc.  Add several user commands for
 816         overlay debugging.  Add support for a "generic" form of automatically
 817         reading overlay mapping info from the inferior (based on the default
 818         (simple) overlay manager which Cygnus provides as an example).
 819         * symtab.[ch]: add functions find_pc_sect_symtab(),
 820         find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
 821         for lookup; modify lookup_symbol and decode_line_1() to use them;
 822         modify find_function_start_sal() to account for overlay sections;
 823         add macro INIT_SAL() for initializing struct symtab_and_line.
 824         * target.c: fix a comment in the declaration of target_ops.

 833         new code to skip over MIPS16 thunks.
 834         (mips_frame_chain): Skip over MIPS16 thunks.
 835         * config/mips/tm-mips.h (mips_in_call_stub, mips_in_return_stub,
