7120         * aclocal.m4:  Remove Make-common.in from dependencies.
7121         * (distclean):  Remove targ-vals.def.
7122
7123         * aclocal.m4 (SIM_AC_COMMON):  Move contents of Make-common.in
7124         into here.  Makes insertion into makefiles easier.  Also, change
7125         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
7126         targ-map.o, and run are built.  They are now built in the
7127         individual simulator directories, taking sources from ../common as
7128         necessary.  This replaces the merging of libcommon.a into
7129         linsim.a, which was problematic for the WinGDB build process.
7130         * run.c:  Include config.h from . instead of ../common.
7131         * Make-common.in:  Remove.  It's no longer necessary.

7151         * aclocal.m4: Mark the fact that --enable-sim-bswap isn't host
7152         specific.
7153         (SIM_AC_OUTPUT): Don't build Makefile if CONFIG_FILES="".

7160         Only process -c ifdef SIM_HAVE_SIMCACHE.
7161         Only process -p/-s ifdef SIM_HAVE_PROFILE.
7162         Parse program name from argv[0] and use in error messages.
7163         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
7164         Add support for incomplete h8/300 termination indicators.
7165         (usage): Make more verbose.
7166         * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.

7203
7204         * run.c (main): Removed SH specific comments, so source is
7205         generic. Also updated to only load relevant sections. Moved
7206         sim_open() to after callback attach (to match GDB).
