-/*
- * NSC/Cyrix CPU indexed register access. Must be inlined instead of
- * macros to ensure correct access ordering
- * Access order is always 0x22 (=offset), 0x23 (=value)
- *
- * When using the old macros a line like
- * setCx86(CX86_CCR2, getCx86(CX86_CCR2) | 0x88);
- * gets expanded to:
- * do {
- * outb((CX86_CCR2), 0x22);
- * outb((({
- * outb((CX86_CCR2), 0x22);
- * inb(0x23);
- * }) | 0x88), 0x23);
- * } while (0);
- *
- * which in fact violates the access order (= 0x22, 0x22, 0x23, 0x23).
