 375         * simops.c: Fix CF and CX computation for add instructions.
 376
 377         * simops.c: Leave the upper 8 bits alone for logical ops.
 378         Mask off high 8 bits before doing any shifts/rotates.
 379         Fix carry bit handling in rotates again.

 386
 387         * simops.c: Fix overflow computation for "cmp" and "sub"
 388         instructions.
 389
 390         * simops.c: Use the right register for "jmp (an)" and "jsr (an)".
 391
 392         * interp.c (hash): Improve hashing for 3 byte instructions.
 393
 394         * simops.c: Fix extraction of 16/24bit immediates for some
 395         instructions.  "cmp" instructions only modify the PSW.
 396         Fix various thinkos when extracting register operands too.

 408         (store_mem): Handle storing 3 byte quantities.
 409
 410         * simops.c: Fix various typos/thinkos.
 411
 412         * interp.c (load_mem_big, load_mem, store_mem): Fix thinko in
 413         code to handle 24bit addresses.
