6132
6133         * sim-endian.h, sim-endian-n.h (offset_N): New functions - return
6134         a pointer into the middle of a host word.

6138
6139         * callback.c: If HAVE_CONFIG_H is defined, include config.h from
6140         autoconf.  If HAVE_UNISTD_H is defined, include unistd.h to get
6141         appropriate definitions of read, write, etc.  Add prototype for
6142         system.

6146         * Makefile.in (libcommon.a): Delete.
6147         (callback.o,targ-map.o): Delete, moved to Make-common.in.
6148         (gentmap,targ-vals.h,targ-map.c): Likewise.
6149         (run-autoconf): Delete.
6150         * aclocal.m4 (SIM_AC_OUTPUT): Redo creation of Makefile.
6151         (common makefile fragment): Moved back into ...
6152         * Make-common.in: Resurrect.

6162
6163         * aclocal.m4 (COMMON_MAKEFILE_FRAG):  Quote a couple of $'s in

6166 Thu Jan 23 13:35:03 1997  Stu Grossman  (grossman@critters.cygnus.com)
6167
6168         * aclocal.m4:  Remove Make-common.in from dependencies.
6169         * (distclean):  Remove targ-vals.def.
6170
6171         * aclocal.m4 (SIM_AC_COMMON):  Move contents of Make-common.in
6172         into here.  Makes insertion into makefiles easier.  Also, change
6173         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
6174         targ-map.o, and run are built.  They are now built in the
6175         individual simulator directories, taking sources from ../common as
6176         necessary.  This replaces the merging of libcommon.a into
6177         linsim.a, which was problematic for the WinGDB build process.
6178         * run.c:  Include config.h from . instead of ../common.
6179         * Make-common.in:  Remove.  It's no longer necessary.

6210         Parse program name from argv[0] and use in error messages.
6211         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
6212         Add support for incomplete h8/300 termination indicators.
6213         (usage): Make more verbose.
6214         * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.
