792 * defs.h utils.c (error warning): Make message be const.
793 * main.c (fputs_unfiltered): Only send gdb_stdout and gdb_stderr

802 (readchar): Improve doc. Handle random serial errors.
803 (expect): Disable notice_quit code. It's busted. Remove
804 serial error handling (it's now handled in readchar). Remove
805 remote_debug echoing. That's handled in readchar as well.
806 (e7000_parse_device): Remove serial_flag arg. It's not
808 (e7000_open): Split into two pieces. Second part is
809 e7000_start_remote, and is error protected. Now, when we connect
810 to the target, we setup the initial frame and registers so that
811 the user gets an immediate indication of where the target is.
812 (gch): Remove debug output. That's handled by readchar.
813 (e7000_read_inferior_memory): Handle errors better.
814 (_initialize_remote_e7000): Get rid of `<xxx>' things from

887 * gdbserver/Makefile.in (INSTALL_XFORM): Remove.
888 (INSTALL_XFORM1): Remove.
889 (install-only): Use $(program_transform_name) directly, rather

907 Mon Apr 14 11:55:27 1997 Geoffrey Noer <noer@pizza.cygnus.com>
909 * config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
910 since gcc automatically includes it
912 Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com>
914 * procfs.c: Substantial (but incomplete) changes to support
915 sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo
916 struct now has substructs like struct flt_ctl instead of
917 just a fltset_t and has a ctl_fd, status_fd, as_fd, and
918 map_fd instead of a single fd. Non-sysv4.2mp procfs models
919 still have the structs and multiple fds, but don't use the
920 entire struct and the four fds all point to the same thing.
921 We use PROCFS_USE_READ_WRITE to decide whether to talk to
922 procfs with reads/writes or use ioctl instead. We use
923 HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
924 multiple fds or not. PROC_NAME_FMT is split out into
925 CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
926 STATUS_PROC_NAME_FMT.
928 (procfs_notice_signals): now a necessary wrapper around
929 (notice_signals): which are the new guts for noticing signals
930 (open_proc_file): gets a new flag arg used in sysv4.2mp to
931 determine whether or not to attempt to open the ctl_fd.
932 (procfs_read_status): new local function, reads procfs status
933 (procfs_write_pcwstop): new local function, writes a PCWSTOP
934 (procfs_write_pckill): new local function, writes a PCKILL
935 (unconditionally_kill_inferior): remove signo since we now
936 just call procfs_write_pckill().
937 (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
938 (proc_iterate_over_mappings): the whole function is ifdefed
939 on UNIXWARE to keep things readable.
941 Expanded the syscall_table to include new potential sysv4.2mp
942 members. Note that all ifdefs of UNIXWARE should be eliminated
943 if possible or renamed to describe what's being selected for a
944 bit better. Sysv4.2mp and IRIX both have SYS_sproc so the
945 IRIX specific code now also checks it's not UNIXWARE.
947 * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
948 HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
949 * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
950 "/debug/%d" as PROC_NAME_FMT used to be
952 Wed Apr 9 11:36:14 1997 Jeffrey A Law (law@cygnus.com)
954 * mn10300-tdep.c: Almost completely rewritten based on mn10200
956 * config/mn10300/tm-mn10300.h: Likewise.
958 Tue Apr 8 10:45:24 1997 Stu Grossman (grossman@critters.cygnus.com)
960 * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}: Remove
961 remote-pa.o from TDEPFILES. Nobody uses it, and besides, it's a
962 lousy out-of-date clone of remote.c.
964 Fri Apr 4 08:21:21 1997 Stu Grossman (grossman@critters.cygnus.com)
966 * remote.c: Fix problems realized while showering.
967 * (hexnumlen): Add prototype. Use max, not min.
968 * (remote_write_bytes remote_read_bytes): Fix max packet size
969 calculations to properly account for packet overhead. Also handle
970 (probably rare) case where remote_register_buf_size isn't set.
972 * remote.c: Fix doc for `C' and `S' commands to indicate full
974 * (remote_ops extended_remote_ops remote_desc remote_write_size):
976 * (remote_fetch_registers remote_write_bytes remote_read_bytes):
977 Record size of response to fetch registers command, use this to
978 limit size of memory read and write commands.
979 * (push_remote_target): New function to make it possible to have
980 another target switch to the remote target.
981 * target.h: Add prototype for push_remote_target.
982 * sh-tdep.c (sh_frame_find_saved_regs): Fix sign extension bugs
983 for hosts which default to unsigned chars (such as SGI's).
984 * (_initialize_sh_tdep): Don't set remote_write_size. It's now
985 handled automatically in remote.c.
987 Thu Apr 3 15:10:30 1997 Michael Snyder <msnyder@cleaver.cygnus.com>
989 * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
990 find_pc_sect_function(), find_pc_sect_partial_function(): new
991 functions for debugging overlays; pc without section is ambiguous.
992 * breakpoint.[ch]: add section pointer to breakpoint struct;
993 add section argument to check_duplicates(); check section as well
994 as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
995 breakpoint_thread_match(), bpstat_stop_status()];
996 add section argument to describe_other_breakpoints();
997 use INIT_SAL() macro to zero-out new sal structures;
998 make resolve_sal_pc() fix up the sal's section as well as its pc;
999 match on section + pc in clear_command() and delete_breakpoint();
1000 account for overlay sections in insert_breakpoints(),
1001 remove_breakpoint() and breakpoint_re_set_one();
1002 all this to support overlays where a PC is not unique.
1003 * exec.c: change xfer_memory() to handle overlay sections.
1004 * findvar.c: change read_var_value() to handle overlay sections.

1028 translating between VMA and LMA address ranges, determining if an
1029 overlay section is mapped, etc. Add several user commands for
1030 overlay debugging. Add support for a "generic" form of automatically
1031 reading overlay mapping info from the inferior (based on the default
1032 (simple) overlay manager which Cygnus provides as an example).
1033 * symtab.[ch]: add functions find_pc_sect_symtab(),
1034 find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
1035 for lookup; modify lookup_symbol and decode_line_1() to use them;
