 361         * interp.c: OP should be an array of 32bit operands!
 362         (v850_callback): Declare.
 363         (do_format_5): Fix extraction of OP[0].
 364         (sim_size): Remove debugging printf.
 365         (sim_set_callbacks): Do something useful.

 367         * simops.c: Simplify code for computing targets of bCC
 368         insns.   Invert 's' bit if 'ov' bit is set for some
 369         instructions.  Fix 'cy' bit handling for numerous
 370         instructions.  Make the simulator stop when a halt
 371         instruction is encountered.  Very crude support for
 372         emulated syscalls (trap 0).
 373         * v850_sim.h: Include "callback.h" and declare
 374         v850_callback.  Items in the operand array are 32bits.

 379         opcode.

 381         register value (duh...)
