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

716 uses of SERIAL_READCHAR with readchar, which has better error
718 * (e7000_parse_device): Add prototype.
719 (readchar): Improve doc. Handle random serial errors.
720 (expect): Disable notice_quit code. It's busted. Remove
721 serial error handling (it's now handled in readchar). Remove
722 remote_debug echoing. That's handled in readchar as well.
723 (e7000_parse_device): Remove serial_flag arg. It's not
725 (e7000_open): Split into two pieces. Second part is
726 e7000_start_remote, and is error protected. Now, when we connect
727 to the target, we setup the initial frame and registers so that
728 the user gets an immediate indication of where the target is.
729 (gch): Remove debug output. That's handled by readchar.
730 (e7000_read_inferior_memory): Handle errors better.
731 (_initialize_remote_e7000): Get rid of `<xxx>' things from
732 command names. They show up when doing completion and confuse
734 * ser-e7kpc.c: Get rid of the DLL's since we can access the device
735 directly from Win32s and Win95. Get rid of debugify crud.
736 * serial.c: Remove debugify cruft.
737 * (serial_logchar serial_log_command serial_write serial_readchar
738 serial_send_break serial_close): Merge common functionality into

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

972 (mips_init_frame_pc): Declare.
973 * infrun.c (wait_for_inferior): Use new IGNORE_HELPER_CALL macro
974 to decide if certain library function calls should be ignored.
976 Wed Apr 2 14:16:51 1997 Doug Evans <dje@canuck.cygnus.com>
978 * remote-sim.c (gdbsim_open): Check return code from sim_open.
979 Update call to sim_open (new arg SIM_OPEN_DEBUG).
