6505
6506 * aclocal.m4: Remove Make-common.in from dependencies.
6507 * (distclean): Remove targ-vals.def.
6508
6509 * aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.in
6510 into here. Makes insertion into makefiles easier. Also, change
6511 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
6512 targ-map.o, and run are built. They are now built in the
6513 individual simulator directories, taking sources from ../common as
6514 necessary. This replaces the merging of libcommon.a into
6515 linsim.a, which was problematic for the WinGDB build process.
6516 * run.c: Include config.h from . instead of ../common.
6517 * Make-common.in: Remove. It's no longer necessary.

6537 * aclocal.m4: Mark the fact that --enable-sim-bswap isn't host
6538 specific.

6543 * run.c: #include ../common/config.h, tconfig.h.
6544 (myname): New static global.
6545 (main): Recognize new options -a, -c. Also recognize -h if h8/300.
6546 Only process -c ifdef SIM_HAVE_SIMCACHE.
6547 Only process -p/-s ifdef SIM_HAVE_PROFILE.
6548 Parse program name from argv[0] and use in error messages.
6549 Pass sim_args to sim_open. Pass prog_args to sim_create_inferior.
6550 Add support for incomplete h8/300 termination indicators.
