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

 742         * simops.c: Define accessor macros to extract register
 743         values from instructions.  Use them consistently.
 744
 745         * interp.c: Delete unused global variable "OP".
 746         (sim_resume): Remove unused variable "opcode".
 747         * simops.c: Fix some uninitialized variable problems, add
 748         parens to fix various -Wall warnings.
 749
 750         * gencode.c (write_header): Add "insn" and "extension" arguments
 751         to the OP_* declarations.
 752         (write_template): Similarly for function templates.
 753         * interp.c (insn, extension): Remove global variables.  Instead
 754         pass them as arguments to the OP_* functions.
 755         * mn10300_sim.h: Remove decls for "insn" and "extension".
 756         * simops.c (OP_*): Accept "insn" and "extension" as arguments
 757         instead of using globals.
