4256Fri Jan 24 10:37:17 1997 Stu Grossman (grossman@critters.cygnus.com)
4257
4258 * aclocal.m4 (COMMON_MAKEFILE_FRAG): Quote a couple of $'s in
4259 comments and single quotes. Fixes a problem found on hpux.
4260
4261Thu Jan 23 13:35:03 1997 Stu Grossman (grossman@critters.cygnus.com)
4262
4263 * aclocal.m4: Remove Make-common.in from dependencies.
4264 * (distclean): Remove targ-vals.def.
4265
4266 * aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.in
4267 into here. Makes insertion into makefiles easier. Also, change
4268 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
4269 targ-map.o, and run are built. They are now built in the
4270 individual simulator directories, taking sources from ../common as
4271 necessary. This replaces the merging of libcommon.a into
4272 linsim.a, which was problematic for the WinGDB build process.
4273 * run.c: Include config.h from . instead of ../common.
4274 * Make-common.in: Remove. It's no longer necessary.

4294 * aclocal.m4: Mark the fact that --enable-sim-bswap isn't host
4295 specific.

4317Tue Oct 15 11:16:31 1996 Jeffrey A Law (law@cygnus.com)
4318
4319 * run.c (main): Don't print out anything if the signal

4346
4347 * run.c (main): Removed SH specific comments, so source is
