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

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

829 * serial.c: Remove debugify cruft.
830 * (serial_logchar serial_log_command serial_write serial_readchar
831 serial_send_break serial_close): Merge common functionality into

897 * gdbserver/Makefile.in (INSTALL_XFORM): Remove.
898 (INSTALL_XFORM1): Remove.
899 (install-only): Use $(program_transform_name) directly, rather

917 Mon Apr 14 11:55:27 1997 Geoffrey Noer <noer@pizza.cygnus.com>
919 * config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
920 since gcc automatically includes it
922 Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com>
924 * procfs.c: Substantial (but incomplete) changes to support
925 sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo
926 struct now has substructs like struct flt_ctl instead of
927 just a fltset_t and has a ctl_fd, status_fd, as_fd, and
928 map_fd instead of a single fd. Non-sysv4.2mp procfs models
929 still have the structs and multiple fds, but don't use the
930 entire struct and the four fds all point to the same thing.
931 We use PROCFS_USE_READ_WRITE to decide whether to talk to
932 procfs with reads/writes or use ioctl instead. We use
933 HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
934 multiple fds or not. PROC_NAME_FMT is split out into
935 CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
936 STATUS_PROC_NAME_FMT.
938 (procfs_notice_signals): now a necessary wrapper around
939 (notice_signals): which are the new guts for noticing signals
940 (open_proc_file): gets a new flag arg used in sysv4.2mp to
941 determine whether or not to attempt to open the ctl_fd.
942 (procfs_read_status): new local function, reads procfs status
943 (procfs_write_pcwstop): new local function, writes a PCWSTOP
944 (procfs_write_pckill): new local function, writes a PCKILL
945 (unconditionally_kill_inferior): remove signo since we now
946 just call procfs_write_pckill().
947 (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
948 (proc_iterate_over_mappings): the whole function is ifdefed
949 on UNIXWARE to keep things readable.
951 Expanded the syscall_table to include new potential sysv4.2mp
952 members. Note that all ifdefs of UNIXWARE should be eliminated
953 if possible or renamed to describe what's being selected for a
954 bit better. Sysv4.2mp and IRIX both have SYS_sproc so the
955 IRIX specific code now also checks it's not UNIXWARE.
957 * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
958 HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
959 * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
960 "/debug/%d" as PROC_NAME_FMT used to be
962 Wed Apr 9 11:36:14 1997 Jeffrey A Law (law@cygnus.com)
964 * mn10300-tdep.c: Almost completely rewritten based on mn10200
966 * config/mn10300/tm-mn10300.h: Likewise.
968 Tue Apr 8 10:45:24 1997 Stu Grossman (grossman@critters.cygnus.com)
970 * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}: Remove
971 remote-pa.o from TDEPFILES. Nobody uses it, and besides, it's a
972 lousy out-of-date clone of remote.c.
974 Fri Apr 4 08:21:21 1997 Stu Grossman (grossman@critters.cygnus.com)
976 * remote.c: Fix problems realized while showering.
977 * (hexnumlen): Add prototype. Use max, not min.
978 * (remote_write_bytes remote_read_bytes): Fix max packet size
979 calculations to properly account for packet overhead. Also handle
980 (probably rare) case where remote_register_buf_size isn't set.
982 * remote.c: Fix doc for `C' and `S' commands to indicate full
984 * (remote_ops extended_remote_ops remote_desc remote_write_size):
986 * (remote_fetch_registers remote_write_bytes remote_read_bytes):
987 Record size of response to fetch registers command, use this to
988 limit size of memory read and write commands.
989 * (push_remote_target): New function to make it possible to have
990 another target switch to the remote target.
991 * target.h: Add prototype for push_remote_target.
992 * sh-tdep.c (sh_frame_find_saved_regs): Fix sign extension bugs
993 for hosts which default to unsigned chars (such as SGI's).
994 * (_initialize_sh_tdep): Don't set remote_write_size. It's now
995 handled automatically in remote.c.
997 Thu Apr 3 15:10:30 1997 Michael Snyder <msnyder@cleaver.cygnus.com>
999 * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
1000 find_pc_sect_function(), find_pc_sect_partial_function(): new
1001 functions for debugging overlays; pc without section is ambiguous.
1002 * breakpoint.[ch]: add section pointer to breakpoint struct;
1003 add section argument to check_duplicates(); check section as well
1004 as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
1005 breakpoint_thread_match(), bpstat_stop_status()];
1006 add section argument to describe_other_breakpoints();

1038 translating between VMA and LMA address ranges, determining if an
1039 overlay section is mapped, etc. Add several user commands for
1040 overlay debugging. Add support for a "generic" form of automatically
1041 reading overlay mapping info from the inferior (based on the default
1042 (simple) overlay manager which Cygnus provides as an example).
1043 * symtab.[ch]: add functions find_pc_sect_symtab(),
1044 find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
1045 for lookup; modify lookup_symbol and decode_line_1() to use them;
1046 modify find_function_start_sal() to account for overlay sections;
