 371         (sim_size): Remove debugging printf.

 377         instructions.  Make the simulator stop when a halt
 378         instruction is encountered.  Very crude support for

 380         * v850_sim.h: Include "callback.h" and declare
 381         v850_callback.  Items in the operand array are 32bits.
