Hi Dale,
I'm pretty uncomfortable with this, because it means that we're tying
down the register order.
How about something like:
if (Darwin32) {
switch (RegNo) {
case X86::AL: case X86::AH: case X86::AX: return 0;
case X86::EDI: ...
} else if (darwin64) {
switch (RegNo) {
...
} else {
}
That way we don't break EH/debug info if registers are reordered or
added in the future.
-Chris
