5457
5458 * aclocal.m4 (COMMON_MAKEFILE_FRAG): Quote a couple of $'s in
5459 comments and single quotes. Fixes a problem found on hpux.
5460
5461Thu Jan 23 13:35:03 1997 Stu Grossman (grossman@critters.cygnus.com)
5462
5463 * aclocal.m4: Remove Make-common.in from dependencies.
5464 * (distclean): Remove targ-vals.def.
5465
5466 * aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.in
5467 into here. Makes insertion into makefiles easier. Also, change
5468 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
5469 targ-map.o, and run are built. They are now built in the
5470 individual simulator directories, taking sources from ../common as
5471 necessary. This replaces the merging of libcommon.a into
5472 linsim.a, which was problematic for the WinGDB build process.
5473 * run.c: Include config.h from . instead of ../common.
5474 * Make-common.in: Remove. It's no longer necessary.

5493 * Make-common.in (Makefile): Set CONFIG_HEADERS="".
5494 * aclocal.m4: Mark the fact that --enable-sim-bswap isn't host
5495 specific.
5496 (SIM_AC_OUTPUT): Don't build Makefile if CONFIG_FILES="".

5546
5547 * run.c (main): Removed SH specific comments, so source is
