3398         autoconf.  If HAVE_UNISTD_H is defined, include unistd.h to get
3399         appropriate definitions of read, write, etc.  Add prototype for
3400         system.

3403
3404         * Makefile.in (libcommon.a): Delete.
3405         (callback.o,targ-map.o): Delete, moved to Make-common.in.
3406         (gentmap,targ-vals.h,targ-map.c): Likewise.
3407         (run-autoconf): Delete.
3408         * aclocal.m4 (SIM_AC_OUTPUT): Redo creation of Makefile.
3409         (common makefile fragment): Moved back into ...
3410         * Make-common.in: Resurrect.
3411         * configure.in (AC_LINK_FILES): Delete, unnecessary now.
3412         * configure: Regenerated.

3414 Fri Jan 31 07:16:49 1997  Doug Evans  <dje@canuck.cygnus.com>
3415
3416         * aclocal.m4 (SIM_AC_COMMON): Move COMMON_MAKEFILE_FRAG from here.
3417         (SIM_AC_OUTPUT): To here.

3419 Fri Jan 24 10:37:17 1997  Stu Grossman  (grossman@critters.cygnus.com)
3420
3421         * aclocal.m4 (COMMON_MAKEFILE_FRAG):  Quote a couple of $'s in
3422         comments and single quotes.  Fixes a problem found on hpux.
3423
3424 Thu Jan 23 13:35:03 1997  Stu Grossman  (grossman@critters.cygnus.com)
3425
3426         * aclocal.m4:  Remove Make-common.in from dependencies.
3427         * (distclean):  Remove targ-vals.def.
3428
3429         * aclocal.m4 (SIM_AC_COMMON):  Move contents of Make-common.in
3430         into here.  Makes insertion into makefiles easier.  Also, change
3431         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
3432         targ-map.o, and run are built.  They are now built in the
3433         individual simulator directories, taking sources from ../common as
3434         necessary.  This replaces the merging of libcommon.a into
3435         linsim.a, which was problematic for the WinGDB build process.
3436         * run.c:  Include config.h from . instead of ../common.
3437         * Make-common.in:  Remove.  It's no longer necessary.

3455
3456         * Make-common.in (Makefile): Set CONFIG_HEADERS="".
3457         * aclocal.m4: Mark the fact that --enable-sim-bswap isn't host
3458         specific.
3459         (SIM_AC_OUTPUT): Don't build Makefile if CONFIG_FILES="".

3467         Only process -p/-s ifdef SIM_HAVE_PROFILE.
3468         Parse program name from argv[0] and use in error messages.
3469         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
3470         Add support for incomplete h8/300 termination indicators.
3471         (usage): Make more verbose.
3472         * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.

3483         number is zero (ie no signal).

3509
3510         * run.c (main): Removed SH specific comments, so source is
3511         generic. Also updated to only load relevant sections. Moved
3512         sim_open() to after callback attach (to match GDB).
