29 (arch, cpu, decode, cpu-decode, defs, desc): Place the name of the

5054
5055 * aclocal.m4 (COMMON_MAKEFILE_FRAG): Quote a couple of $'s in
5056 comments and single quotes. Fixes a problem found on hpux.
5057
5058Thu Jan 23 13:35:03 1997 Stu Grossman (grossman@critters.cygnus.com)
5059
5060 * aclocal.m4: Remove Make-common.in from dependencies.
5061 * (distclean): Remove targ-vals.def.
5062
5063 * aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.in
5064 into here. Makes insertion into makefiles easier. Also, change
5065 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
5066 targ-map.o, and run are built. They are now built in the
5067 individual simulator directories, taking sources from ../common as
5068 necessary. This replaces the merging of libcommon.a into
5069 linsim.a, which was problematic for the WinGDB build process.
5070 * run.c: Include config.h from . instead of ../common.
5071 * Make-common.in: Remove. It's no longer necessary.
5072

5091 * aclocal.m4: Mark the fact that --enable-sim-bswap isn't host
5092 specific.
5093 (SIM_AC_OUTPUT): Don't build Makefile if CONFIG_FILES="".

5143
5144 * run.c (main): Removed SH specific comments, so source is
