5425         * Makefile.in (libcommon.a): Delete.
5426         (callback.o,targ-map.o): Delete, moved to Make-common.in.
5427         (gentmap,targ-vals.h,targ-map.c): Likewise.
5428         (run-autoconf): Delete.
5429         * aclocal.m4 (SIM_AC_OUTPUT): Redo creation of Makefile.
5430         (common makefile fragment): Moved back into ...
5431         * Make-common.in: Resurrect.

5441
5442         * aclocal.m4 (COMMON_MAKEFILE_FRAG):  Quote a couple of $'s in
5443         comments and single quotes.  Fixes a problem found on hpux.

5445 Thu Jan 23 13:35:03 1997  Stu Grossman  (grossman@critters.cygnus.com)
5446
5447         * aclocal.m4:  Remove Make-common.in from dependencies.
5448         * (distclean):  Remove targ-vals.def.
5449
5450         * aclocal.m4 (SIM_AC_COMMON):  Move contents of Make-common.in
5451         into here.  Makes insertion into makefiles easier.  Also, change
5452         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
5453         targ-map.o, and run are built.  They are now built in the
5454         individual simulator directories, taking sources from ../common as
5455         necessary.  This replaces the merging of libcommon.a into
5456         linsim.a, which was problematic for the WinGDB build process.
5457         * run.c:  Include config.h from . instead of ../common.
5458         * Make-common.in:  Remove.  It's no longer necessary.

5488         Only process -p/-s ifdef SIM_HAVE_PROFILE.
5489         Parse program name from argv[0] and use in error messages.
5490         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
5491         Add support for incomplete h8/300 termination indicators.
5492         (usage): Make more verbose.
5493         * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.

5530
5531         * run.c (main): Removed SH specific comments, so source is
5532         generic. Also updated to only load relevant sections. Moved
5533         sim_open() to after callback attach (to match GDB).
5534
