980 insns. Invert 's' bit if 'ov' bit is set for some
981 instructions. Fix 'cy' bit handling for numerous
982 instructions. Make the simulator stop when a halt
983 instruction is encountered. Very crude support for
984 emulated syscalls (trap 0).
985 * v850_sim.h: Include "callback.h" and declare
986 v850_callback. Items in the operand array are 32bits.
