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

5059
5060 * aclocal.m4 (COMMON_MAKEFILE_FRAG): Quote a couple of $'s in
5061 comments and single quotes. Fixes a problem found on hpux.
5062
5063Thu Jan 23 13:35:03 1997 Stu Grossman (grossman@critters.cygnus.com)
5064
5065 * aclocal.m4: Remove Make-common.in from dependencies.
5066 * (distclean): Remove targ-vals.def.
5067
5068 * aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.in
5069 into here. Makes insertion into makefiles easier. Also, change
5070 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
5071 targ-map.o, and run are built. They are now built in the
5072 individual simulator directories, taking sources from ../common as
5073 necessary. This replaces the merging of libcommon.a into
5074 linsim.a, which was problematic for the WinGDB build process.
5075 * run.c: Include config.h from . instead of ../common.
5076 * Make-common.in: Remove. It's no longer necessary.

5148
5149 * run.c (main): Removed SH specific comments, so source is
