3828 * configure.in (AC_LINK_FILES): Delete, unnecessary now.
3829 * configure: Regenerated.
3831 Fri Jan 31 07:16:49 1997 Doug Evans <dje@canuck.cygnus.com>
3833 * aclocal.m4 (SIM_AC_COMMON): Move COMMON_MAKEFILE_FRAG from here.
3834 (SIM_AC_OUTPUT): To here.
3836 Fri Jan 24 10:37:17 1997 Stu Grossman (grossman@critters.cygnus.com)
3838 * aclocal.m4 (COMMON_MAKEFILE_FRAG): Quote a couple of $'s in
3839 comments and single quotes. Fixes a problem found on hpux.
3841 Thu Jan 23 13:35:03 1997 Stu Grossman (grossman@critters.cygnus.com)
3843 * aclocal.m4: Remove Make-common.in from dependencies.
3844 * (distclean): Remove targ-vals.def.
3846 * aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.in
3847 into here. Makes insertion into makefiles easier. Also, change
3848 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
3849 targ-map.o, and run are built. They are now built in the
3850 individual simulator directories, taking sources from ../common as
3851 necessary. This replaces the merging of libcommon.a into
3852 linsim.a, which was problematic for the WinGDB build process.
3853 * run.c: Include config.h from . instead of ../common.
3854 * Make-common.in: Remove. It's no longer necessary.
3856 Mon Dec 16 15:02:33 1996 Ian Lance Taylor <ian@cygnus.com>
3858 * Make-common.in (ALL_CLAGS): Put CFLAGS at the end.
3859 (.c.o): Put $(ALL_CFLAGS) before the file being compiled.
3861 Wed Dec 11 11:30:58 1996 Jim Wilson <wilson@cygnus.com>

3868 (os_error): New function.
3869 (default_callback): Add os_error.
3871 Mon Nov 25 19:44:35 1996 Doug Evans <dje@canuck.cygnus.com>
3873 * Make-common.in (Makefile): Set CONFIG_HEADERS="".
3874 * aclocal.m4: Mark the fact that --enable-sim-bswap isn't host
3875 specific.
3876 (SIM_AC_OUTPUT): Don't build Makefile if CONFIG_FILES="".
3878 Wed Nov 20 01:11:04 1996 Doug Evans <dje@canuck.cygnus.com>
3880 * run.c: #include ../common/config.h, tconfig.h.
3881 (myname): New static global.
3882 (main): Recognize new options -a, -c. Also recognize -h if h8/300.
3883 Only process -c ifdef SIM_HAVE_SIMCACHE.
3884 Only process -p/-s ifdef SIM_HAVE_PROFILE.
3885 Parse program name from argv[0] and use in error messages.
3886 Pass sim_args to sim_open. Pass prog_args to sim_create_inferior.
3887 Add support for incomplete h8/300 termination indicators.
3888 (usage): Make more verbose.
3889 * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.

3895 * run.c: Include stdarg.h if __STDC__.
3897 Tue Oct 15 11:16:31 1996 Jeffrey A Law (law@cygnus.com)
3899 * run.c (main): Don't print out anything if the signal
3900 number is zero (ie no signal).
3902 Tue Oct 15 11:20:44 1996 Michael Meissner <meissner@tiktok.cygnus.com>
3904 * run.c (main): Print out if the program raised a signal.
3906 Wed Sep 18 09:52:14 1996 Michael Meissner <meissner@tiktok.cygnus.com>
3908 * run.c (exec_bfd): Rename from sim_bfd, to use the gdb name.
3909 (main): Ditto.

3923 * run.c (main): Use new bfd_big_endian macro.
3925 Wed Nov 8 15:49:49 1995 James G. Smith <jsmith@pasanda.cygnus.co.uk>
3927 * run.c (main): Removed SH specific comments, so source is
3928 generic. Also updated to only load relevant sections. Moved
3929 sim_open() to after callback attach (to match GDB).
3931 * run.1: Removed SH specific comments.
3933 Sat Oct 21 12:31:01 1995 Jim Wilson <wilson@chestnut.cygnus.com>
3935 * run.c (main): Always return sigrc at end.
3937 Tue Oct 10 12:03:13 1995 J.T. Conklin <jtc@rtl.cygnus.com>
3939 * run.c (main): Print error diagnostic and exit if bfd_openr() or
3940 bfd_check_format() fails.
