 358         * simops.c: Simplify code for computing targets of bCC
 359         insns.   Invert 's' bit if 'ov' bit is set for some
 360         instructions.  Fix 'cy' bit handling for numerous
 361         instructions.  Make the simulator stop when a halt
 362         instruction is encountered.  Very crude support for
 363         emulated syscalls (trap 0).
 364         * v850_sim.h: Include "callback.h" and declare
 365         v850_callback.  Items in the operand array are 32bits.

 370         opcode.
