1784         (callback.o,targ-map.o): Delete, moved to Make-common.in.
1785         (gentmap,targ-vals.h,targ-map.c): Likewise.
1786         (run-autoconf): Delete.
1787         * aclocal.m4 (SIM_AC_OUTPUT): Redo creation of Makefile.
1788         (common makefile fragment): Moved back into ...

1796         (SIM_AC_OUTPUT): To here.
1797
1798 Fri Jan 24 10:37:17 1997  Stu Grossman  (grossman@critters.cygnus.com)
1799
1800         * aclocal.m4 (COMMON_MAKEFILE_FRAG):  Quote a couple of $'s in

1806         * (distclean):  Remove targ-vals.def.
1807
1808         * aclocal.m4 (SIM_AC_COMMON):  Move contents of Make-common.in
1809         into here.  Makes insertion into makefiles easier.  Also, change
1810         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
1811         targ-map.o, and run are built.  They are now built in the
1812         individual simulator directories, taking sources from ../common as
1813         necessary.  This replaces the merging of libcommon.a into
1814         linsim.a, which was problematic for the WinGDB build process.
1815         * run.c:  Include config.h from . instead of ../common.
1816         * Make-common.in:  Remove.  It's no longer necessary.

1847         Parse program name from argv[0] and use in error messages.
1848         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
1849         Add support for incomplete h8/300 termination indicators.
1850         (usage): Make more verbose.
1851         * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.

1888
1889         * run.c (main): Removed SH specific comments, so source is
