1401         * Makefile.in (libcommon.a): Delete.
1402         (callback.o,targ-map.o): Delete, moved to Make-common.in.
1403         (gentmap,targ-vals.h,targ-map.c): Likewise.
1404         (run-autoconf): Delete.
1405         * aclocal.m4 (SIM_AC_OUTPUT): Redo creation of Makefile.
1406         (common makefile fragment): Moved back into ...
1407         * Make-common.in: Resurrect.
1408         * configure.in (AC_LINK_FILES): Delete, unnecessary now.

1412
1413         * aclocal.m4 (SIM_AC_COMMON): Move COMMON_MAKEFILE_FRAG from here.
1414         (SIM_AC_OUTPUT): To here.

1417
1418         * aclocal.m4 (COMMON_MAKEFILE_FRAG):  Quote a couple of $'s in

1421 Thu Jan 23 13:35:03 1997  Stu Grossman  (grossman@critters.cygnus.com)
1422
1423         * aclocal.m4:  Remove Make-common.in from dependencies.
1424         * (distclean):  Remove targ-vals.def.
1425
1426         * aclocal.m4 (SIM_AC_COMMON):  Move contents of Make-common.in
1427         into here.  Makes insertion into makefiles easier.  Also, change
1428         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
1429         targ-map.o, and run are built.  They are now built in the
1430         individual simulator directories, taking sources from ../common as
1431         necessary.  This replaces the merging of libcommon.a into
1432         linsim.a, which was problematic for the WinGDB build process.
1433         * run.c:  Include config.h from . instead of ../common.
1434         * Make-common.in:  Remove.  It's no longer necessary.

1451 Mon Nov 25 19:44:35 1996  Doug Evans  <dje@canuck.cygnus.com>
1452
1453         * Make-common.in (Makefile): Set CONFIG_HEADERS="".
1454         * aclocal.m4: Mark the fact that --enable-sim-bswap isn't host
1455         specific.
1456         (SIM_AC_OUTPUT): Don't build Makefile if CONFIG_FILES="".

1464         Only process -p/-s ifdef SIM_HAVE_PROFILE.
1465         Parse program name from argv[0] and use in error messages.
1466         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
1467         Add support for incomplete h8/300 termination indicators.
1468         (usage): Make more verbose.
1469         * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.

1507         * run.c (main): Removed SH specific comments, so source is
1508         generic. Also updated to only load relevant sections. Moved
1509         sim_open() to after callback attach (to match GDB).
