2733
2734         * aclocal.m4:  Remove Make-common.in from dependencies.
2735         * (distclean):  Remove targ-vals.def.
2736
2737         * aclocal.m4 (SIM_AC_COMMON):  Move contents of Make-common.in
2738         into here.  Makes insertion into makefiles easier.  Also, change
2739         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
2740         targ-map.o, and run are built.  They are now built in the
2741         individual simulator directories, taking sources from ../common as
2742         necessary.  This replaces the merging of libcommon.a into
2743         linsim.a, which was problematic for the WinGDB build process.
2744         * run.c:  Include config.h from . instead of ../common.
2745         * Make-common.in:  Remove.  It's no longer necessary.

2762 Mon Nov 25 19:44:35 1996  Doug Evans  <dje@canuck.cygnus.com>
2763
2764         * Make-common.in (Makefile): Set CONFIG_HEADERS="".
2765         * aclocal.m4: Mark the fact that --enable-sim-bswap isn't host
2766         specific.
2767         (SIM_AC_OUTPUT): Don't build Makefile if CONFIG_FILES="".
2768

2772         (myname): New static global.
2773         (main): Recognize new options -a, -c.  Also recognize -h if h8/300.
2774         Only process -c ifdef SIM_HAVE_SIMCACHE.
2775         Only process -p/-s ifdef SIM_HAVE_PROFILE.
2776         Parse program name from argv[0] and use in error messages.
2777         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
2778         Add support for incomplete h8/300 termination indicators.
2779         (usage): Make more verbose.
2780         * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.
2781         * Makefile.in,Make-common.in,callback.c: New files.

2819         generic. Also updated to only load relevant sections. Moved
2820         sim_open() to after callback attach (to match GDB).
