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

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

839 (gdb_os_poll_quit): New function. Check for a quit pending on the
843 Wed Apr 16 12:33:06 1997 Andrew Cagney <cagney@b1.cygnus.com>
845 * Makefile.in (install-only): Make list of gdbtcl files to install
846 explicit - was picking up files such as ChangeLog etc.

878 * gdbserver/Makefile.in (INSTALL_XFORM): Remove.
879 (INSTALL_XFORM1): Remove.
880 (install-only): Use $(program_transform_name) directly, rather

898 Mon Apr 14 11:55:27 1997 Geoffrey Noer <noer@pizza.cygnus.com>
900 * config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
901 since gcc automatically includes it
903 Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com>
905 * procfs.c: Substantial (but incomplete) changes to support
906 sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo
907 struct now has substructs like struct flt_ctl instead of
908 just a fltset_t and has a ctl_fd, status_fd, as_fd, and
909 map_fd instead of a single fd. Non-sysv4.2mp procfs models
910 still have the structs and multiple fds, but don't use the
911 entire struct and the four fds all point to the same thing.
912 We use PROCFS_USE_READ_WRITE to decide whether to talk to
913 procfs with reads/writes or use ioctl instead. We use
914 HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
915 multiple fds or not. PROC_NAME_FMT is split out into
916 CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
917 STATUS_PROC_NAME_FMT.
919 (procfs_notice_signals): now a necessary wrapper around
920 (notice_signals): which are the new guts for noticing signals
921 (open_proc_file): gets a new flag arg used in sysv4.2mp to
922 determine whether or not to attempt to open the ctl_fd.
923 (procfs_read_status): new local function, reads procfs status
924 (procfs_write_pcwstop): new local function, writes a PCWSTOP
925 (procfs_write_pckill): new local function, writes a PCKILL
926 (unconditionally_kill_inferior): remove signo since we now
927 just call procfs_write_pckill().
928 (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
929 (proc_iterate_over_mappings): the whole function is ifdefed
930 on UNIXWARE to keep things readable.
932 Expanded the syscall_table to include new potential sysv4.2mp
933 members. Note that all ifdefs of UNIXWARE should be eliminated
934 if possible or renamed to describe what's being selected for a
935 bit better. Sysv4.2mp and IRIX both have SYS_sproc so the
936 IRIX specific code now also checks it's not UNIXWARE.
938 * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
939 HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
940 * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
941 "/debug/%d" as PROC_NAME_FMT used to be
943 Wed Apr 9 11:36:14 1997 Jeffrey A Law (law@cygnus.com)
945 * mn10300-tdep.c: Almost completely rewritten based on mn10200
947 * config/mn10300/tm-mn10300.h: Likewise.
949 Tue Apr 8 10:45:24 1997 Stu Grossman (grossman@critters.cygnus.com)
951 * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}: Remove
952 remote-pa.o from TDEPFILES. Nobody uses it, and besides, it's a
953 lousy out-of-date clone of remote.c.
955 Fri Apr 4 08:21:21 1997 Stu Grossman (grossman@critters.cygnus.com)
957 * remote.c: Fix problems realized while showering.
958 * (hexnumlen): Add prototype. Use max, not min.
959 * (remote_write_bytes remote_read_bytes): Fix max packet size
960 calculations to properly account for packet overhead. Also handle
961 (probably rare) case where remote_register_buf_size isn't set.
963 * remote.c: Fix doc for `C' and `S' commands to indicate full
965 * (remote_ops extended_remote_ops remote_desc remote_write_size):
967 * (remote_fetch_registers remote_write_bytes remote_read_bytes):
968 Record size of response to fetch registers command, use this to
969 limit size of memory read and write commands.
970 * (push_remote_target): New function to make it possible to have
971 another target switch to the remote target.
972 * target.h: Add prototype for push_remote_target.
973 * sh-tdep.c (sh_frame_find_saved_regs): Fix sign extension bugs
974 for hosts which default to unsigned chars (such as SGI's).
975 * (_initialize_sh_tdep): Don't set remote_write_size. It's now
976 handled automatically in remote.c.
978 Thu Apr 3 15:10:30 1997 Michael Snyder <msnyder@cleaver.cygnus.com>
980 * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
981 find_pc_sect_function(), find_pc_sect_partial_function(): new
982 functions for debugging overlays; pc without section is ambiguous.
983 * breakpoint.[ch]: add section pointer to breakpoint struct;
984 add section argument to check_duplicates(); check section as well
985 as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
986 breakpoint_thread_match(), bpstat_stop_status()];
987 add section argument to describe_other_breakpoints();
988 use INIT_SAL() macro to zero-out new sal structures;
989 make resolve_sal_pc() fix up the sal's section as well as its pc;
990 match on section + pc in clear_command() and delete_breakpoint();
991 account for overlay sections in insert_breakpoints(),
992 remove_breakpoint() and breakpoint_re_set_one();
993 all this to support overlays where a PC is not unique.
994 * exec.c: change xfer_memory() to handle overlay sections.
995 * findvar.c: change read_var_value() to handle overlay sections.
996 * frame.h: declaration for block_for_pc_sect() [blockframe.c].
997 * infcmd.c: jump_command() warns against jumping into an overlay
998 that's not in memory. Also use INIT_SAL() to initialize sals.
999 * infrun.c: wait_for_inferior() sets a flag to invalidate cached
1000 overlay state information; Also use INIT_SAL() to init sals.
1001 * m32r-rom.c: modify load routines to use LMA instead of VMA.
1002 * m32r-stub.c: mask exit value down to 8 bits; screen out any

1019 translating between VMA and LMA address ranges, determining if an
1020 overlay section is mapped, etc. Add several user commands for
1021 overlay debugging. Add support for a "generic" form of automatically
1022 reading overlay mapping info from the inferior (based on the default
1023 (simple) overlay manager which Cygnus provides as an example).
1024 * symtab.[ch]: add functions find_pc_sect_symtab(),
1025 find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
1026 for lookup; modify lookup_symbol and decode_line_1() to use them;
1027 modify find_function_start_sal() to account for overlay sections;
