5767
5768         * aclocal.m4 (SIM_AC_COMMON): Move COMMON_MAKEFILE_FRAG from here.
5769         (SIM_AC_OUTPUT): To here.

5771 Fri Jan 24 10:37:17 1997  Stu Grossman  (grossman@critters.cygnus.com)
5772
5773         * aclocal.m4 (COMMON_MAKEFILE_FRAG):  Quote a couple of $'s in
5774         comments and single quotes.  Fixes a problem found on hpux.
5775
5776 Thu Jan 23 13:35:03 1997  Stu Grossman  (grossman@critters.cygnus.com)
5777
5778         * aclocal.m4:  Remove Make-common.in from dependencies.
5779         * (distclean):  Remove targ-vals.def.
5780
5781         * aclocal.m4 (SIM_AC_COMMON):  Move contents of Make-common.in
5782         into here.  Makes insertion into makefiles easier.  Also, change
5783         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
5784         targ-map.o, and run are built.  They are now built in the
5785         individual simulator directories, taking sources from ../common as
5786         necessary.  This replaces the merging of libcommon.a into
5787         linsim.a, which was problematic for the WinGDB build process.
5788         * run.c:  Include config.h from . instead of ../common.
5789         * Make-common.in:  Remove.  It's no longer necessary.

5805
5806 Mon Nov 25 19:44:35 1996  Doug Evans  <dje@canuck.cygnus.com>
5807
5808         * Make-common.in (Makefile): Set CONFIG_HEADERS="".
5809         * aclocal.m4: Mark the fact that --enable-sim-bswap isn't host
5810         specific.
5811         (SIM_AC_OUTPUT): Don't build Makefile if CONFIG_FILES="".

5818         Only process -c ifdef SIM_HAVE_SIMCACHE.
5819         Only process -p/-s ifdef SIM_HAVE_PROFILE.
5820         Parse program name from argv[0] and use in error messages.
5821         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
5822         Add support for incomplete h8/300 termination indicators.
5823         (usage): Make more verbose.
5824         * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.

5861
5862         * run.c (main): Removed SH specific comments, so source is
5863         generic. Also updated to only load relevant sections. Moved
5864         sim_open() to after callback attach (to match GDB).
