5451
5452 * aclocal.m4: Remove Make-common.in from dependencies.
5453 * (distclean): Remove targ-vals.def.
5454
5455 * aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.in
5456 into here. Makes insertion into makefiles easier. Also, change
5457 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
5458 targ-map.o, and run are built. They are now built in the
5459 individual simulator directories, taking sources from ../common as
5460 necessary. This replaces the merging of libcommon.a into
5461 linsim.a, which was problematic for the WinGDB build process.
5462 * run.c: Include config.h from . instead of ../common.
5463 * Make-common.in: Remove. It's no longer necessary.
5464

5482 * Make-common.in (Makefile): Set CONFIG_HEADERS="".
5483 * aclocal.m4: Mark the fact that --enable-sim-bswap isn't host
5484 specific.
5485 (SIM_AC_OUTPUT): Don't build Makefile if CONFIG_FILES="".

5489 * run.c: #include ../common/config.h, tconfig.h.
5490 (myname): New static global.
5491 (main): Recognize new options -a, -c. Also recognize -h if h8/300.
5492 Only process -c ifdef SIM_HAVE_SIMCACHE.
5493 Only process -p/-s ifdef SIM_HAVE_PROFILE.
5494 Parse program name from argv[0] and use in error messages.
5495 Pass sim_args to sim_open. Pass prog_args to sim_create_inferior.
5496 Add support for incomplete h8/300 termination indicators.

5535
5536 * run.c (main): Removed SH specific comments, so source is
5537 generic. Also updated to only load relevant sections. Moved
