7470         * Makefile.in (libcommon.a): Delete.
7471         (callback.o,targ-map.o): Delete, moved to Make-common.in.
7472         (gentmap,targ-vals.h,targ-map.c): Likewise.
7473         (run-autoconf): Delete.
7474         * aclocal.m4 (SIM_AC_OUTPUT): Redo creation of Makefile.
7475         (common makefile fragment): Moved back into ...

7486
7487         * aclocal.m4 (COMMON_MAKEFILE_FRAG):  Quote a couple of $'s in
7488         comments and single quotes.  Fixes a problem found on hpux.

7491
7492         * aclocal.m4:  Remove Make-common.in from dependencies.
7493         * (distclean):  Remove targ-vals.def.
7494
7495         * aclocal.m4 (SIM_AC_COMMON):  Move contents of Make-common.in
7496         into here.  Makes insertion into makefiles easier.  Also, change
7497         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
7498         targ-map.o, and run are built.  They are now built in the
7499         individual simulator directories, taking sources from ../common as
7500         necessary.  This replaces the merging of libcommon.a into
7501         linsim.a, which was problematic for the WinGDB build process.
7502         * run.c:  Include config.h from . instead of ../common.
7503         * Make-common.in:  Remove.  It's no longer necessary.

7533         Only process -p/-s ifdef SIM_HAVE_PROFILE.
7534         Parse program name from argv[0] and use in error messages.
7535         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
7536         Add support for incomplete h8/300 termination indicators.
7537         (usage): Make more verbose.
7538         * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.

7575
7576         * run.c (main): Removed SH specific comments, so source is
7577         generic. Also updated to only load relevant sections. Moved
7578         sim_open() to after callback attach (to match GDB).
7579
