522 satisfy symbol dependancy in solib.c (core_ops).
523 * target.[ch] conditionalize Mach-specific signals so that they
524 won't show up in non-Mach gdb's!
525 * thread.c: change name of static function "thread_switch" to
526 "switch_to_thread", to avoid conflict with Mach global symbol;
527 move thread_cmd_list to global scope so targets can add their

677 * defs.h utils.c (error warning): Make message be const.
678 * main.c (fputs_unfiltered): Only send gdb_stdout and gdb_stderr
679 to hook. Otherwise send it to fputs.

682 * remote-e7000.c: Remove debugify stuff. Change printf, fprintf
683 to _filtered forms to make output appear in GUIs. Replace all
684 uses of SERIAL_READCHAR with readchar, which has better error
686 * (e7000_parse_device): Add prototype.
687 (readchar): Improve doc. Handle random serial errors.
688 (expect): Disable notice_quit code. It's busted. Remove
689 serial error handling (it's now handled in readchar). Remove
690 remote_debug echoing. That's handled in readchar as well.
691 (e7000_parse_device): Remove serial_flag arg. It's not
693 (e7000_open): Split into two pieces. Second part is
694 e7000_start_remote, and is error protected. Now, when we connect
695 to the target, we setup the initial frame and registers so that
696 the user gets an immediate indication of where the target is.
697 (gch): Remove debug output. That's handled by readchar.
698 (e7000_read_inferior_memory): Handle errors better.
699 (_initialize_remote_e7000): Get rid of `<xxx>' things from
700 command names. They show up when doing completion and confuse
702 * ser-e7kpc.c: Get rid of the DLL's since we can access the device
703 directly from Win32s and Win95. Get rid of debugify crud.
704 * serial.c: Remove debugify cruft.
705 * (serial_logchar serial_log_command serial_write serial_readchar
706 serial_send_break serial_close): Merge common functionality into

772 * gdbserver/Makefile.in (INSTALL_XFORM): Remove.
773 (INSTALL_XFORM1): Remove.
774 (install-only): Use $(program_transform_name) directly, rather

787 Mon Apr 14 16:25:10 1997 Ian Lance Taylor <ian@cygnus.com>
789 * gdbserver/Makefile.in (INSTALL): Change install.sh to
792 Mon Apr 14 11:55:27 1997 Geoffrey Noer <noer@pizza.cygnus.com>
794 * config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
795 since gcc automatically includes it
797 Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com>
799 * procfs.c: Substantial (but incomplete) changes to support
800 sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo
801 struct now has substructs like struct flt_ctl instead of
802 just a fltset_t and has a ctl_fd, status_fd, as_fd, and
803 map_fd instead of a single fd. Non-sysv4.2mp procfs models
804 still have the structs and multiple fds, but don't use the
805 entire struct and the four fds all point to the same thing.
806 We use PROCFS_USE_READ_WRITE to decide whether to talk to
807 procfs with reads/writes or use ioctl instead. We use
808 HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
809 multiple fds or not. PROC_NAME_FMT is split out into
810 CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
811 STATUS_PROC_NAME_FMT.
813 (procfs_notice_signals): now a necessary wrapper around
814 (notice_signals): which are the new guts for noticing signals
815 (open_proc_file): gets a new flag arg used in sysv4.2mp to
816 determine whether or not to attempt to open the ctl_fd.
817 (procfs_read_status): new local function, reads procfs status
818 (procfs_write_pcwstop): new local function, writes a PCWSTOP
819 (procfs_write_pckill): new local function, writes a PCKILL
820 (unconditionally_kill_inferior): remove signo since we now
821 just call procfs_write_pckill().
822 (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
823 (proc_iterate_over_mappings): the whole function is ifdefed
824 on UNIXWARE to keep things readable.
826 Expanded the syscall_table to include new potential sysv4.2mp
827 members. Note that all ifdefs of UNIXWARE should be eliminated
828 if possible or renamed to describe what's being selected for a
829 bit better. Sysv4.2mp and IRIX both have SYS_sproc so the
830 IRIX specific code now also checks it's not UNIXWARE.
832 * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
833 HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
834 * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
835 "/debug/%d" as PROC_NAME_FMT used to be
837 Wed Apr 9 11:36:14 1997 Jeffrey A Law (law@cygnus.com)
839 * mn10300-tdep.c: Almost completely rewritten based on mn10200
841 * config/mn10300/tm-mn10300.h: Likewise.
843 Tue Apr 8 10:45:24 1997 Stu Grossman (grossman@critters.cygnus.com)
845 * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}: Remove
846 remote-pa.o from TDEPFILES. Nobody uses it, and besides, it's a
847 lousy out-of-date clone of remote.c.
849 Fri Apr 4 08:21:21 1997 Stu Grossman (grossman@critters.cygnus.com)
851 * remote.c: Fix problems realized while showering.
852 * (hexnumlen): Add prototype. Use max, not min.
853 * (remote_write_bytes remote_read_bytes): Fix max packet size
854 calculations to properly account for packet overhead. Also handle
855 (probably rare) case where remote_register_buf_size isn't set.
857 * remote.c: Fix doc for `C' and `S' commands to indicate full
859 * (remote_ops extended_remote_ops remote_desc remote_write_size):
861 * (remote_fetch_registers remote_write_bytes remote_read_bytes):
862 Record size of response to fetch registers command, use this to
863 limit size of memory read and write commands.
864 * (push_remote_target): New function to make it possible to have
865 another target switch to the remote target.
866 * target.h: Add prototype for push_remote_target.
867 * sh-tdep.c (sh_frame_find_saved_regs): Fix sign extension bugs
868 for hosts which default to unsigned chars (such as SGI's).
869 * (_initialize_sh_tdep): Don't set remote_write_size. It's now
870 handled automatically in remote.c.
872 Thu Apr 3 15:10:30 1997 Michael Snyder <msnyder@cleaver.cygnus.com>
874 * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
875 find_pc_sect_function(), find_pc_sect_partial_function(): new
876 functions for debugging overlays; pc without section is ambiguous.
877 * breakpoint.[ch]: add section pointer to breakpoint struct;
878 add section argument to check_duplicates(); check section as well
879 as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
880 breakpoint_thread_match(), bpstat_stop_status()];
881 add section argument to describe_other_breakpoints();
882 use INIT_SAL() macro to zero-out new sal structures;
883 make resolve_sal_pc() fix up the sal's section as well as its pc;
884 match on section + pc in clear_command() and delete_breakpoint();
885 account for overlay sections in insert_breakpoints(),
886 remove_breakpoint() and breakpoint_re_set_one();
887 all this to support overlays where a PC is not unique.
888 * exec.c: change xfer_memory() to handle overlay sections.
889 * findvar.c: change read_var_value() to handle overlay sections.
890 * frame.h: declaration for block_for_pc_sect() [blockframe.c].
891 * infcmd.c: jump_command() warns against jumping into an overlay
892 that's not in memory. Also use INIT_SAL() to initialize sals.
893 * infrun.c: wait_for_inferior() sets a flag to invalidate cached
894 overlay state information; Also use INIT_SAL() to init sals.
895 * m32r-rom.c: modify load routines to use LMA instead of VMA.
896 * m32r-stub.c: mask exit value down to 8 bits; screen out any
897 memory read/writes in the range 600000 to a00000, and ff680000
898 to ff800000 (hangs because nothing is mapped there); fix strcpy().
899 * maint.c: maintenance command "translate-address" supports overlays.
900 * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
901 * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
902 this constitutes gdb's internal overlay mapping table. Add macro
903 ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
904 Add function find_pc_sect_section().
905 * printcmd.c: modify print_address_symbolic() with overlay smarts;
906 modify address_info() with overlay smarts; add function sym_info()
907 to support the INFO SYMBOL command (translate address to symbol(s));
908 modify disassemble_command() to work on unmapped overlays.
909 * source.c: use INIT_SAL() to initialize sals.
910 * symfile.[ch]: change generic_load() to use section's LMA address
911 instead of VMA address, for overlay sections.
912 Add numerous functions for finding a PC's section / overlay,
913 translating between VMA and LMA address ranges, determining if an
914 overlay section is mapped, etc. Add several user commands for
915 overlay debugging. Add support for a "generic" form of automatically
916 reading overlay mapping info from the inferior (based on the default
917 (simple) overlay manager which Cygnus provides as an example).
918 * symtab.[ch]: add functions find_pc_sect_symtab(),
919 find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
920 for lookup; modify lookup_symbol and decode_line_1() to use them;
921 modify find_function_start_sal() to account for overlay sections;
922 add macro INIT_SAL() for initializing struct symtab_and_line.
923 * target.c: fix a comment in the declaration of target_ops.
925 Thu Apr 3 10:31:12 1997 Mark Alexander <marka@cygnus.com>
927 * mips-tdep.c (mips_in_call_stub, mips_in_return_stub,
928 mips_skip_stub, mips_ignore_helper): New functions for dealing
929 with MIPS16 call/return thunks.
930 (mips_init_frame_pc_first): New function to implement
931 INIT_FRAME_PC_FIRST macro; includes code from old macro plus
932 new code to skip over MIPS16 thunks.
933 (mips_frame_chain): Skip over MIPS16 thunks.
934 * config/mips/tm-mips.h (mips_in_call_stub, mips_in_return_stub,

940 (mips_init_frame_pc): Declare.
941 * infrun.c (wait_for_inferior): Use new IGNORE_HELPER_CALL macro
942 to decide if certain library function calls should be ignored.
944 Wed Apr 2 14:16:51 1997 Doug Evans <dje@canuck.cygnus.com>
946 * remote-sim.c (gdbsim_open): Check return code from sim_open.
