1059         * Makefile.in (libcommon.a): Delete.
1060         (callback.o,targ-map.o): Delete, moved to Make-common.in.
1061         (gentmap,targ-vals.h,targ-map.c): Likewise.
1062         (run-autoconf): Delete.
1063         * aclocal.m4 (SIM_AC_OUTPUT): Redo creation of Makefile.
1064         (common makefile fragment): Moved back into ...
1065         * Make-common.in: Resurrect.
1066         * configure.in (AC_LINK_FILES): Delete, unnecessary now.
1067         * configure: Regenerated.

1070
1071         * aclocal.m4 (SIM_AC_COMMON): Move COMMON_MAKEFILE_FRAG from here.
1072         (SIM_AC_OUTPUT): To here.

1075
1076         * aclocal.m4 (COMMON_MAKEFILE_FRAG):  Quote a couple of $'s in
1077         comments and single quotes.  Fixes a problem found on hpux.
1078
1079 Thu Jan 23 13:35:03 1997  Stu Grossman  (grossman@critters.cygnus.com)
1080
1081         * aclocal.m4:  Remove Make-common.in from dependencies.
1082         * (distclean):  Remove targ-vals.def.
1083
1084         * aclocal.m4 (SIM_AC_COMMON):  Move contents of Make-common.in
1085         into here.  Makes insertion into makefiles easier.  Also, change
1086         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
1087         targ-map.o, and run are built.  They are now built in the
1088         individual simulator directories, taking sources from ../common as
1089         necessary.  This replaces the merging of libcommon.a into
1090         linsim.a, which was problematic for the WinGDB build process.
1091         * run.c:  Include config.h from . instead of ../common.
1092         * Make-common.in:  Remove.  It's no longer necessary.

1108
1109 Mon Nov 25 19:44:35 1996  Doug Evans  <dje@canuck.cygnus.com>
1110
1111         * Make-common.in (Makefile): Set CONFIG_HEADERS="".
1112         * aclocal.m4: Mark the fact that --enable-sim-bswap isn't host
1113         specific.
1114         (SIM_AC_OUTPUT): Don't build Makefile if CONFIG_FILES="".

1121         Only process -c ifdef SIM_HAVE_SIMCACHE.
1122         Only process -p/-s ifdef SIM_HAVE_PROFILE.
1123         Parse program name from argv[0] and use in error messages.
1124         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
1125         Add support for incomplete h8/300 termination indicators.
1126         (usage): Make more verbose.
1127         * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.

1164
1165         * run.c (main): Removed SH specific comments, so source is
1166         generic. Also updated to only load relevant sections. Moved
1167         sim_open() to after callback attach (to match GDB).
