9909e232c0 * interp.c (hash): Make this an inline function
when compiling with GCC.  Simplify.

d81352b8b8 * interp.c: OP should be an array of 32bit operands!
(v850_callback): Declare.
        (do_format_5): Fix extraction of OP[0].
        (sim_size): Remove debugging printf.
        (sim_set_callbacks): Do something useful.
        (sim_stop_reason): Gross hacks to get c-torture running.
        * simops.c: Simplify code for computing targets of bCC
        insns.   Invert 's' bit if 'ov' bit is set for some
        instructions.  Fix 'cy' bit handling for numerous
        instructions.  Make the simulator stop when a halt
        instruction is encountered.  Very crude support for
        emulated syscalls (trap 0).
        * v850_sim.h: Include "callback.h" and declare
        v850_callback.  Items in the operand array are 32bits.
Fixes & syscall stuff.
