5432
5433         * aclocal.m4:  Remove Make-common.in from dependencies.
5434         * (distclean):  Remove targ-vals.def.
5435
5436         * aclocal.m4 (SIM_AC_COMMON):  Move contents of Make-common.in
5437         into here.  Makes insertion into makefiles easier.  Also, change
5438         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
5439         targ-map.o, and run are built.  They are now built in the
5440         individual simulator directories, taking sources from ../common as
5441         necessary.  This replaces the merging of libcommon.a into
5442         linsim.a, which was problematic for the WinGDB build process.
5443         * run.c:  Include config.h from . instead of ../common.
5444         * Make-common.in:  Remove.  It's no longer necessary.

5464         * aclocal.m4: Mark the fact that --enable-sim-bswap isn't host
5465         specific.
5466         (SIM_AC_OUTPUT): Don't build Makefile if CONFIG_FILES="".

5473         Only process -c ifdef SIM_HAVE_SIMCACHE.
5474         Only process -p/-s ifdef SIM_HAVE_PROFILE.
5475         Parse program name from argv[0] and use in error messages.
5476         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
5477         Add support for incomplete h8/300 termination indicators.
5478         (usage): Make more verbose.
5479         * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.

5516
5517         * run.c (main): Removed SH specific comments, so source is
5518         generic. Also updated to only load relevant sections. Moved
5519         sim_open() to after callback attach (to match GDB).
