2079
2080         * Makefile.in (libcommon.a): Delete.
2081         (callback.o,targ-map.o): Delete, moved to Make-common.in.
2082         (gentmap,targ-vals.h,targ-map.c): Likewise.
2083         (run-autoconf): Delete.
2084         * aclocal.m4 (SIM_AC_OUTPUT): Redo creation of Makefile.
2085         (common makefile fragment): Moved back into ...
2086         * Make-common.in: Resurrect.
2087         * configure.in (AC_LINK_FILES): Delete, unnecessary now.
2088         * configure: Regenerated.

2090 Fri Jan 31 07:16:49 1997  Doug Evans  <dje@canuck.cygnus.com>
2091
2092         * aclocal.m4 (SIM_AC_COMMON): Move COMMON_MAKEFILE_FRAG from here.
2093         (SIM_AC_OUTPUT): To here.
2094
2095 Fri Jan 24 10:37:17 1997  Stu Grossman  (grossman@critters.cygnus.com)
2096
2097         * aclocal.m4 (COMMON_MAKEFILE_FRAG):  Quote a couple of $'s in
2098         comments and single quotes.  Fixes a problem found on hpux.
2099
2100 Thu Jan 23 13:35:03 1997  Stu Grossman  (grossman@critters.cygnus.com)
2101
2102         * aclocal.m4:  Remove Make-common.in from dependencies.
2103         * (distclean):  Remove targ-vals.def.
2104
2105         * aclocal.m4 (SIM_AC_COMMON):  Move contents of Make-common.in
2106         into here.  Makes insertion into makefiles easier.  Also, change
2107         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
2108         targ-map.o, and run are built.  They are now built in the
2109         individual simulator directories, taking sources from ../common as
2110         necessary.  This replaces the merging of libcommon.a into
2111         linsim.a, which was problematic for the WinGDB build process.
2112         * run.c:  Include config.h from . instead of ../common.
2113         * Make-common.in:  Remove.  It's no longer necessary.

2121
2122         * run.c (main): Set target_byte_order before call to sim_open.
2123
2124 Sun Dec  8 18:22:06 1996  Doug Evans  <dje@canuck.cygnus.com>

2126         * callback.c: #include <stdlib.h>
2127         (os_error): New function.
2128         (default_callback): Add os_error.
2129
2130 Mon Nov 25 19:44:35 1996  Doug Evans  <dje@canuck.cygnus.com>
2131
2132         * Make-common.in (Makefile): Set CONFIG_HEADERS="".
2133         * aclocal.m4: Mark the fact that --enable-sim-bswap isn't host
2134         specific.
2135         (SIM_AC_OUTPUT): Don't build Makefile if CONFIG_FILES="".
2136

2142         Only process -c ifdef SIM_HAVE_SIMCACHE.
2143         Only process -p/-s ifdef SIM_HAVE_PROFILE.
2144         Parse program name from argv[0] and use in error messages.
2145         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
2146         Add support for incomplete h8/300 termination indicators.
2147         (usage): Make more verbose.
2148         * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.

2166
2167         * run.c (exec_bfd): Rename from sim_bfd, to use the gdb name.
2168         (main): Ditto.

2186         * run.c (main): Removed SH specific comments, so source is
2187         generic. Also updated to only load relevant sections. Moved
2188         sim_open() to after callback attach (to match GDB).
