 719         * simops.c: Call abort for any instruction that's not currently
 720         simulated.

 722         * simops.c: Define accessor macros to extract register
 723         values from instructions.  Use them consistently.
 724
 725         * interp.c: Delete unused global variable "OP".
 726         (sim_resume): Remove unused variable "opcode".
 727         * simops.c: Fix some uninitialized variable problems, add
 728         parens to fix various -Wall warnings.
 729
 730         * gencode.c (write_header): Add "insn" and "extension" arguments
 731         to the OP_* declarations.
 732         (write_template): Similarly for function templates.
 733         * interp.c (insn, extension): Remove global variables.  Instead
 734         pass them as arguments to the OP_* functions.
 735         * mn10300_sim.h: Remove decls for "insn" and "extension".
 736         * simops.c (OP_*): Accept "insn" and "extension" as arguments
 737         instead of using globals.
