612 * java-exp.y: Combine TRUE and FALSE into BOOLEAN_LITERAL.
613 (Avoids name clash with broken AIX header files.)
615 Sat Apr 19 01:49:37 1997 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
617 * serial.c (serial_log_command): Fix fputs_unfiltered calls.

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

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

671 directly from Win32s and Win95. Get rid of debugify crud.
672 * serial.c: Remove debugify cruft.
673 * (serial_logchar serial_log_command serial_write serial_readchar
674 serial_send_break serial_close): Merge common functionality into

740 * gdbserver/Makefile.in (INSTALL_XFORM): Remove.
741 (INSTALL_XFORM1): Remove.
742 (install-only): Use $(program_transform_name) directly, rather

744 (uninstall): Transform name.
746 Mon Apr 14 17:06:27 1997 Mark Alexander <marka@cygnus.com>
748 * remote-mips.c (mips_load): Ensure that PC gets updated

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

955 * remote-sim.c (gdb_os_{,e}vprintf_filtered): Change stdarg type
956 to va_list from void *, since va_list might not be a pointer
960 Fri Mar 28 17:04:02 1997 Jason Molenda (crash@godzilla.cygnus.co.jp)
962 * Makefile.in (gdbtk.o): look for GDBTK_LIBRARY in $(datadir) by
