4660
4661 * Makefile.in (libcommon.a): Delete.
4662 (callback.o,targ-map.o): Delete, moved to Make-common.in.
4663 (gentmap,targ-vals.h,targ-map.c): Likewise.
4664 (run-autoconf): Delete.
4665 * aclocal.m4 (SIM_AC_OUTPUT): Redo creation of Makefile.
4666 (common makefile fragment): Moved back into ...
4667 * Make-common.in: Resurrect.
4668 * configure.in (AC_LINK_FILES): Delete, unnecessary now.
4669 * configure: Regenerated.

4671Fri Jan 31 07:16:49 1997 Doug Evans <dje@canuck.cygnus.com>
4672

4677
4678 * aclocal.m4 (COMMON_MAKEFILE_FRAG): Quote a couple of $'s in
4679 comments and single quotes. Fixes a problem found on hpux.
4680
4681Thu Jan 23 13:35:03 1997 Stu Grossman (grossman@critters.cygnus.com)
4682
4683 * aclocal.m4: Remove Make-common.in from dependencies.
4684 * (distclean): Remove targ-vals.def.
4685
4686 * aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.in
4687 into here. Makes insertion into makefiles easier. Also, change
4688 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
4689 targ-map.o, and run are built. They are now built in the
4690 individual simulator directories, taking sources from ../common as
4691 necessary. This replaces the merging of libcommon.a into
4692 linsim.a, which was problematic for the WinGDB build process.
4693 * run.c: Include config.h from . instead of ../common.
4694 * Make-common.in: Remove. It's no longer necessary.

4714 * aclocal.m4: Mark the fact that --enable-sim-bswap isn't host
4715 specific.

4766
4767 * run.c (main): Removed SH specific comments, so source is
