7144         (callback.o,targ-map.o): Delete, moved to Make-common.in.
7145         (gentmap,targ-vals.h,targ-map.c): Likewise.
7146         (run-autoconf): Delete.

7165         * aclocal.m4:  Remove Make-common.in from dependencies.
7166         * (distclean):  Remove targ-vals.def.
7167
7168         * aclocal.m4 (SIM_AC_COMMON):  Move contents of Make-common.in
7169         into here.  Makes insertion into makefiles easier.  Also, change
7170         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
7171         targ-map.o, and run are built.  They are now built in the
7172         individual simulator directories, taking sources from ../common as
7173         necessary.  This replaces the merging of libcommon.a into
7174         linsim.a, which was problematic for the WinGDB build process.
7175         * run.c:  Include config.h from . instead of ../common.
7176         * Make-common.in:  Remove.  It's no longer necessary.

7207         Parse program name from argv[0] and use in error messages.
7208         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
7209         Add support for incomplete h8/300 termination indicators.
7210         (usage): Make more verbose.
7211         * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.
