1490 | (do_format_5): Fix extraction of OP[0]. | |
1491 | (sim_size): Remove debugging printf. | |
1492 | (sim_set_callbacks): Do something useful. | |

1495 | insns. Invert 's' bit if 'ov' bit is set for some | |
1496 | instructions. Fix 'cy' bit handling for numerous | |
1497 | instructions. Make the simulator stop when a halt | |
1498 | instruction is encountered. Very crude support for | |
1499 | emulated syscalls (trap 0). | |
1500 | * v850_sim.h: Include "callback.h" and declare | |
1501 | v850_callback. Items in the operand array are 32bits. | |
