1753         * bits.h, bits.c (SIGN_EXTEND32, SIGN_EXTEND64): New functions,
1754         sign extend a bit within a value.
1755
1756         * sim-endian.h, sim-endian-n.h (offset_N): New functions - return
1757         a pointer into the middle of a host word.

1761
1762         * callback.c: If HAVE_CONFIG_H is defined, include config.h from
1763         autoconf.  If HAVE_UNISTD_H is defined, include unistd.h to get
1764         appropriate definitions of read, write, etc.  Add prototype for
1765         system.

1770         (callback.o,targ-map.o): Delete, moved to Make-common.in.
1771         (gentmap,targ-vals.h,targ-map.c): Likewise.
1772         (run-autoconf): Delete.
1773         * aclocal.m4 (SIM_AC_OUTPUT): Redo creation of Makefile.
1774         (common makefile fragment): Moved back into ...
1775         * Make-common.in: Resurrect.

1785
1786         * aclocal.m4 (COMMON_MAKEFILE_FRAG):  Quote a couple of $'s in

1789 Thu Jan 23 13:35:03 1997  Stu Grossman  (grossman@critters.cygnus.com)
1790
1791         * aclocal.m4:  Remove Make-common.in from dependencies.
1792         * (distclean):  Remove targ-vals.def.
1793
1794         * aclocal.m4 (SIM_AC_COMMON):  Move contents of Make-common.in
1795         into here.  Makes insertion into makefiles easier.  Also, change
1796         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
1797         targ-map.o, and run are built.  They are now built in the
1798         individual simulator directories, taking sources from ../common as
1799         necessary.  This replaces the merging of libcommon.a into
1800         linsim.a, which was problematic for the WinGDB build process.
1801         * run.c:  Include config.h from . instead of ../common.
1802         * Make-common.in:  Remove.  It's no longer necessary.

1832         Only process -p/-s ifdef SIM_HAVE_PROFILE.
1833         Parse program name from argv[0] and use in error messages.
1834         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
1835         Add support for incomplete h8/300 termination indicators.
1836         (usage): Make more verbose.
1837         * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.
