5764
5765         * aclocal.m4:  Remove Make-common.in from dependencies.
5766         * (distclean):  Remove targ-vals.def.
5767
5768         * aclocal.m4 (SIM_AC_COMMON):  Move contents of Make-common.in
5769         into here.  Makes insertion into makefiles easier.  Also, change
5770         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
5771         targ-map.o, and run are built.  They are now built in the
5772         individual simulator directories, taking sources from ../common as
5773         necessary.  This replaces the merging of libcommon.a into
5774         linsim.a, which was problematic for the WinGDB build process.
5775         * run.c:  Include config.h from . instead of ../common.
5776         * Make-common.in:  Remove.  It's no longer necessary.

5796         * aclocal.m4: Mark the fact that --enable-sim-bswap isn't host
5797         specific.
5798         (SIM_AC_OUTPUT): Don't build Makefile if CONFIG_FILES="".

5805         Only process -c ifdef SIM_HAVE_SIMCACHE.
5806         Only process -p/-s ifdef SIM_HAVE_PROFILE.
5807         Parse program name from argv[0] and use in error messages.
5808         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
5809         Add support for incomplete h8/300 termination indicators.
5810         (usage): Make more verbose.
5811         * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.

5848
5849         * run.c (main): Removed SH specific comments, so source is
5850         generic. Also updated to only load relevant sections. Moved
5851         sim_open() to after callback attach (to match GDB).
