2075
2076         * aclocal.m4:  Remove Make-common.in from dependencies.
2077         * (distclean):  Remove targ-vals.def.
2078
2079         * aclocal.m4 (SIM_AC_COMMON):  Move contents of Make-common.in
2080         into here.  Makes insertion into makefiles easier.  Also, change
2081         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
2082         targ-map.o, and run are built.  They are now built in the
2083         individual simulator directories, taking sources from ../common as
2084         necessary.  This replaces the merging of libcommon.a into
2085         linsim.a, which was problematic for the WinGDB build process.
2086         * run.c:  Include config.h from . instead of ../common.
2087         * Make-common.in:  Remove.  It's no longer necessary.

2107         * aclocal.m4: Mark the fact that --enable-sim-bswap isn't host
2108         specific.
2109         (SIM_AC_OUTPUT): Don't build Makefile if CONFIG_FILES="".

2116         Only process -c ifdef SIM_HAVE_SIMCACHE.
2117         Only process -p/-s ifdef SIM_HAVE_PROFILE.
2118         Parse program name from argv[0] and use in error messages.
2119         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
2120         Add support for incomplete h8/300 termination indicators.
2121         (usage): Make more verbose.
2122         * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.
