4261
4262 * aclocal.m4 (COMMON_MAKEFILE_FRAG): Quote a couple of $'s in
4263 comments and single quotes. Fixes a problem found on hpux.
4264
4265Thu Jan 23 13:35:03 1997 Stu Grossman (grossman@critters.cygnus.com)
4266
4267 * aclocal.m4: Remove Make-common.in from dependencies.
4268 * (distclean): Remove targ-vals.def.
4269
4270 * aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.in
4271 into here. Makes insertion into makefiles easier. Also, change
4272 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
4273 targ-map.o, and run are built. They are now built in the
4274 individual simulator directories, taking sources from ../common as
4275 necessary. This replaces the merging of libcommon.a into
4276 linsim.a, which was problematic for the WinGDB build process.
4277 * run.c: Include config.h from . instead of ../common.
4278 * Make-common.in: Remove. It's no longer necessary.
4279

4298 * aclocal.m4: Mark the fact that --enable-sim-bswap isn't host
4299 specific.
4300 (SIM_AC_OUTPUT): Don't build Makefile if CONFIG_FILES="".

4350
4351 * run.c (main): Removed SH specific comments, so source is
4352 generic. Also updated to only load relevant sections. Moved
