3 | * interp.c (sim_open): Cast result of calloc, and make sure NULL | |
4 | was not returned. | |

23 | * d10v-sim.h (simops): Add flag is_long. | |
24 | (State): Add pc_changed. Instructions which update the PC should | |
25 | use the JMP macro which sets this. | |

27 | ||
28 | * gencode.c (write_opcodes): Add is_long field. | |

34 | (sim_resume): Change to logic for setting the PC. Used to increment the | |

37 | (dmem_addr): Fix translation of data segments to unified memory. | |
38 | (sim_ctrl_c): New function. When ^C is received, set stop_simulator flag. | |
