1425         * simops.c: Simplify code for computing targets of bCC
1426         insns.   Invert 's' bit if 'ov' bit is set for some
1427         instructions.  Fix 'cy' bit handling for numerous
1428         instructions.  Make the simulator stop when a halt
1429         instruction is encountered.  Very crude support for
1430         emulated syscalls (trap 0).
1431         * v850_sim.h: Include "callback.h" and declare
1432         v850_callback.  Items in the operand array are 32bits.
