65b784d8a5 * simops.c: Fix register extraction for a two "movbu" variants. 
Somewhat simplify "sub" instructions.
        Correctly sign extend operands for "mul".  Put the correct
        half of the result in MDR for "mul" and "mulu".
        Implement remaining instructions.
        Tweak opcode for "syscall".

a77aa7ec4b * configure: Re-generate. 
* Make-common.in (CSEARCH): Do not include the gdb directory in
        the search path.
        * Make-common.in (SIM_ENDIAN, SIM_HOSTENDIAN, SIM_INLINE,
        SIM_WARNING): Drop, requiring the simulator specific Makefile.in
        to explicitly incorporate these.

        * aclocal.m4 (--enable-sim-alignment); New option. Strongly
        specify the alignment restrictions of the target architecture -
        without this option all alignment restrictions are accomodated.

        assertion statements.
        (--enable-sim-float): New option. Strongly specify the target's
        floating point support.

        included in the simulation.
        (--enable-sim-packages): New option.  Specify the hardware
        packages included in the simulation.
        (--enable-sim-regparm): New option.  Specify that parameters be
        passed in registers instead of on the stack.
        (--enable-sim-reserved-bits): New option. Specify that reserved
        bits within an instruction are are correctly set.
        (--enable-sim-smp): New option. Specify the level of SMP support
        to be included in the simulator.
        (--enable-sim-stdcall): New option.  Specify an alternative
        function call convention.
        (--enable-sim-xor-endian): New option.  Configure xor-endian
        support used by some targets to implement bi-endian support.
