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

625 * (e7000_parse_device): Add prototype.
626 (readchar): Improve doc. Handle random serial errors.
627 (expect): Disable notice_quit code. It's busted. Remove
628 serial error handling (it's now handled in readchar). Remove
629 remote_debug echoing. That's handled in readchar as well.
630 (e7000_parse_device): Remove serial_flag arg. It's not
632 (e7000_open): Split into two pieces. Second part is
633 e7000_start_remote, and is error protected. Now, when we connect
634 to the target, we setup the initial frame and registers so that
635 the user gets an immediate indication of where the target is.
636 (gch): Remove debug output. That's handled by readchar.
637 (e7000_read_inferior_memory): Handle errors better.
638 (_initialize_remote_e7000): Get rid of `<xxx>' things from
639 command names. They show up when doing completion and confuse

726 Mon Apr 14 16:25:10 1997 Ian Lance Taylor <ian@cygnus.com>
728 * gdbserver/Makefile.in (INSTALL): Change install.sh to
731 Mon Apr 14 11:55:27 1997 Geoffrey Noer <noer@pizza.cygnus.com>
733 * config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
734 since gcc automatically includes it
736 Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com>
738 * procfs.c: Substantial (but incomplete) changes to support
739 sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo
740 struct now has substructs like struct flt_ctl instead of
741 just a fltset_t and has a ctl_fd, status_fd, as_fd, and
742 map_fd instead of a single fd. Non-sysv4.2mp procfs models
743 still have the structs and multiple fds, but don't use the
744 entire struct and the four fds all point to the same thing.
745 We use PROCFS_USE_READ_WRITE to decide whether to talk to
746 procfs with reads/writes or use ioctl instead. We use
747 HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
748 multiple fds or not. PROC_NAME_FMT is split out into
749 CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
750 STATUS_PROC_NAME_FMT.
752 (procfs_notice_signals): now a necessary wrapper around
753 (notice_signals): which are the new guts for noticing signals
754 (open_proc_file): gets a new flag arg used in sysv4.2mp to
755 determine whether or not to attempt to open the ctl_fd.
756 (procfs_read_status): new local function, reads procfs status
757 (procfs_write_pcwstop): new local function, writes a PCWSTOP
758 (procfs_write_pckill): new local function, writes a PCKILL
759 (unconditionally_kill_inferior): remove signo since we now
760 just call procfs_write_pckill().
761 (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
762 (proc_iterate_over_mappings): the whole function is ifdefed
763 on UNIXWARE to keep things readable.
765 Expanded the syscall_table to include new potential sysv4.2mp
766 members. Note that all ifdefs of UNIXWARE should be eliminated
767 if possible or renamed to describe what's being selected for a
768 bit better. Sysv4.2mp and IRIX both have SYS_sproc so the
769 IRIX specific code now also checks it's not UNIXWARE.
771 * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
772 HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
773 * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
774 "/debug/%d" as PROC_NAME_FMT used to be
776 Wed Apr 9 11:36:14 1997 Jeffrey A Law (law@cygnus.com)
778 * mn10300-tdep.c: Almost completely rewritten based on mn10200
780 * config/mn10300/tm-mn10300.h: Likewise.
782 Tue Apr 8 10:45:24 1997 Stu Grossman (grossman@critters.cygnus.com)
784 * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}: Remove
785 remote-pa.o from TDEPFILES. Nobody uses it, and besides, it's a
786 lousy out-of-date clone of remote.c.
788 Fri Apr 4 08:21:21 1997 Stu Grossman (grossman@critters.cygnus.com)
790 * remote.c: Fix problems realized while showering.
791 * (hexnumlen): Add prototype. Use max, not min.
792 * (remote_write_bytes remote_read_bytes): Fix max packet size
793 calculations to properly account for packet overhead. Also handle
794 (probably rare) case where remote_register_buf_size isn't set.
796 * remote.c: Fix doc for `C' and `S' commands to indicate full
798 * (remote_ops extended_remote_ops remote_desc remote_write_size):
800 * (remote_fetch_registers remote_write_bytes remote_read_bytes):
801 Record size of response to fetch registers command, use this to
802 limit size of memory read and write commands.
803 * (push_remote_target): New function to make it possible to have
804 another target switch to the remote target.
805 * target.h: Add prototype for push_remote_target.
806 * sh-tdep.c (sh_frame_find_saved_regs): Fix sign extension bugs
807 for hosts which default to unsigned chars (such as SGI's).
808 * (_initialize_sh_tdep): Don't set remote_write_size. It's now
809 handled automatically in remote.c.
811 Thu Apr 3 15:10:30 1997 Michael Snyder <msnyder@cleaver.cygnus.com>
813 * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
814 find_pc_sect_function(), find_pc_sect_partial_function(): new
815 functions for debugging overlays; pc without section is ambiguous.
816 * breakpoint.[ch]: add section pointer to breakpoint struct;
817 add section argument to check_duplicates(); check section as well
818 as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
819 breakpoint_thread_match(), bpstat_stop_status()];
820 add section argument to describe_other_breakpoints();
821 use INIT_SAL() macro to zero-out new sal structures;
822 make resolve_sal_pc() fix up the sal's section as well as its pc;
823 match on section + pc in clear_command() and delete_breakpoint();
824 account for overlay sections in insert_breakpoints(),
825 remove_breakpoint() and breakpoint_re_set_one();
826 all this to support overlays where a PC is not unique.
827 * exec.c: change xfer_memory() to handle overlay sections.
828 * findvar.c: change read_var_value() to handle overlay sections.
829 * frame.h: declaration for block_for_pc_sect() [blockframe.c].
830 * infcmd.c: jump_command() warns against jumping into an overlay
831 that's not in memory. Also use INIT_SAL() to initialize sals.
832 * infrun.c: wait_for_inferior() sets a flag to invalidate cached
833 overlay state information; Also use INIT_SAL() to init sals.
834 * m32r-rom.c: modify load routines to use LMA instead of VMA.
835 * m32r-stub.c: mask exit value down to 8 bits; screen out any
836 memory read/writes in the range 600000 to a00000, and ff680000
837 to ff800000 (hangs because nothing is mapped there); fix strcpy().
838 * maint.c: maintenance command "translate-address" supports overlays.
839 * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
840 * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
841 this constitutes gdb's internal overlay mapping table. Add macro
842 ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
843 Add function find_pc_sect_section().
844 * printcmd.c: modify print_address_symbolic() with overlay smarts;
845 modify address_info() with overlay smarts; add function sym_info()
846 to support the INFO SYMBOL command (translate address to symbol(s));
847 modify disassemble_command() to work on unmapped overlays.
848 * source.c: use INIT_SAL() to initialize sals.
849 * symfile.[ch]: change generic_load() to use section's LMA address
850 instead of VMA address, for overlay sections.
851 Add numerous functions for finding a PC's section / overlay,
852 translating between VMA and LMA address ranges, determining if an
853 overlay section is mapped, etc. Add several user commands for
854 overlay debugging. Add support for a "generic" form of automatically
855 reading overlay mapping info from the inferior (based on the default
856 (simple) overlay manager which Cygnus provides as an example).
857 * symtab.[ch]: add functions find_pc_sect_symtab(),
858 find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
859 for lookup; modify lookup_symbol and decode_line_1() to use them;
860 modify find_function_start_sal() to account for overlay sections;
861 add macro INIT_SAL() for initializing struct symtab_and_line.
862 * target.c: fix a comment in the declaration of target_ops.
864 Thu Apr 3 10:31:12 1997 Mark Alexander <marka@cygnus.com>
866 * mips-tdep.c (mips_in_call_stub, mips_in_return_stub,
867 mips_skip_stub, mips_ignore_helper): New functions for dealing
868 with MIPS16 call/return thunks.
869 (mips_init_frame_pc_first): New function to implement
870 INIT_FRAME_PC_FIRST macro; includes code from old macro plus
871 new code to skip over MIPS16 thunks.
