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

733 uses of SERIAL_READCHAR with readchar, which has better error
735 * (e7000_parse_device): Add prototype.
736 (readchar): Improve doc. Handle random serial errors.
737 (expect): Disable notice_quit code. It's busted. Remove
738 serial error handling (it's now handled in readchar). Remove
739 remote_debug echoing. That's handled in readchar as well.
740 (e7000_parse_device): Remove serial_flag arg. It's not
742 (e7000_open): Split into two pieces. Second part is
743 e7000_start_remote, and is error protected. Now, when we connect
744 to the target, we setup the initial frame and registers so that
745 the user gets an immediate indication of where the target is.
746 (gch): Remove debug output. That's handled by readchar.
747 (e7000_read_inferior_memory): Handle errors better.
748 (_initialize_remote_e7000): Get rid of `<xxx>' things from
749 command names. They show up when doing completion and confuse

752 directly from Win32s and Win95. Get rid of debugify crud.
753 * serial.c: Remove debugify cruft.
754 * (serial_logchar serial_log_command serial_write serial_readchar
755 serial_send_break serial_close): Merge common functionality into

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