515 the same as floatformat_little.
516 (floatformat_from_doublest): Postswap output words for
517 the floatformat_littlebyte_bigwords format.

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

580 Fri Apr 18 17:25:10 1997 Stu Grossman (grossman@critters.cygnus.com)
582 * Makefile.in (SUBDIRS): Add mswin so that make cleanup cleans up
584 * defs.h utils.c (error warning): Make message be const.
585 * main.c (fputs_unfiltered): Only send gdb_stdout and gdb_stderr
586 to hook. Otherwise send it to fputs.
587 * monitor.c monitor.h (monitor_get_dev_name): New function. Does
589 * remote-e7000.c: Remove debugify stuff. Change printf, fprintf
590 to _filtered forms to make output appear in GUIs. Replace all
591 uses of SERIAL_READCHAR with readchar, which has better error
593 * (e7000_parse_device): Add prototype.
594 (readchar): Improve doc. Handle random serial errors.
595 (expect): Disable notice_quit code. It's busted. Remove
596 serial error handling (it's now handled in readchar). Remove
597 remote_debug echoing. That's handled in readchar as well.
598 (e7000_parse_device): Remove serial_flag arg. It's not
600 (e7000_open): Split into two pieces. Second part is
601 e7000_start_remote, and is error protected. Now, when we connect
602 to the target, we setup the initial frame and registers so that
603 the user gets an immediate indication of where the target is.
604 (gch): Remove debug output. That's handled by readchar.
605 (e7000_read_inferior_memory): Handle errors better.
606 (_initialize_remote_e7000): Get rid of `<xxx>' things from
607 command names. They show up when doing completion and confuse
609 * ser-e7kpc.c: Get rid of the DLL's since we can access the device
610 directly from Win32s and Win95. Get rid of debugify crud.
611 * serial.c: Remove debugify cruft.
612 * (serial_logchar serial_log_command serial_write serial_readchar
613 serial_send_break serial_close): Merge common functionality into

640 (gdb_os_poll_quit): New function. Check for a quit pending on the
644 Wed Apr 16 12:33:06 1997 Andrew Cagney <cagney@b1.cygnus.com>
646 * Makefile.in (install-only): Make list of gdbtcl files to install
647 explicit - was picking up files such as ChangeLog etc.

679 * gdbserver/Makefile.in (INSTALL_XFORM): Remove.
680 (INSTALL_XFORM1): Remove.
681 (install-only): Use $(program_transform_name) directly, rather
682 than using $(INSTALL_XFORM) and $(INSTALL_XFORM1).
683 (uninstall): Transform name.
685 Mon Apr 14 17:06:27 1997 Mark Alexander <marka@cygnus.com>
687 * remote-mips.c (mips_load): Ensure that PC gets updated

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

930 * config/mips/tm-mips.h (REGISTER_CONVERT_TO_TYPE,
931 REGISTER_CONVERT_FROM_TYPE): Swap words if target, not host,
932 is big-endian and if registers are 32 bits.

996 * remote-sim.c (gdb_os_vprintf_filtered): Fix to work with non-ANSI
998 (gdb_os_evprintf_filtered): Similarly.
1000 Wed Mar 19 16:13:22 1997 Geoffrey Noer <noer@pizza.cygnus.com>
