620 Sat Apr 19 01:49:37 1997 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
622 * serial.c (serial_log_command): Fix fputs_unfiltered calls.

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

655 * remote-e7000.c: Remove debugify stuff. Change printf, fprintf
656 to _filtered forms to make output appear in GUIs. Replace all
657 uses of SERIAL_READCHAR with readchar, which has better error
659 * (e7000_parse_device): Add prototype.
660 (readchar): Improve doc. Handle random serial errors.
661 (expect): Disable notice_quit code. It's busted. Remove
662 serial error handling (it's now handled in readchar). Remove
663 remote_debug echoing. That's handled in readchar as well.
664 (e7000_parse_device): Remove serial_flag arg. It's not
666 (e7000_open): Split into two pieces. Second part is
667 e7000_start_remote, and is error protected. Now, when we connect
668 to the target, we setup the initial frame and registers so that
669 the user gets an immediate indication of where the target is.
670 (gch): Remove debug output. That's handled by readchar.
671 (e7000_read_inferior_memory): Handle errors better.
672 (_initialize_remote_e7000): Get rid of `<xxx>' things from
673 command names. They show up when doing completion and confuse

676 directly from Win32s and Win95. Get rid of debugify crud.
677 * serial.c: Remove debugify cruft.
678 * (serial_logchar serial_log_command serial_write serial_readchar
679 serial_send_break serial_close): Merge common functionality into

745 * gdbserver/Makefile.in (INSTALL_XFORM): Remove.
746 (INSTALL_XFORM1): Remove.
747 (install-only): Use $(program_transform_name) directly, rather

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