 387
 388         * simops.c: "rts" adds 4 to the stack pointer.
 389
 390         * simops.c: Fix CF and CX computation for add instructions.
 391
 392         * simops.c: Leave the upper 8 bits alone for logical ops.

 401
 402         * simops.c: Fix overflow computation for "cmp" and "sub"
 403         instructions.
 404
 405         * simops.c: Use the right register for "jmp (an)" and "jsr (an)".
 406
 407         * interp.c (hash): Improve hashing for 3 byte instructions.
