Hi Dale,

I still don't understand why you don't just do:

	intVT = MVT::getIntegerType(MVT::getSizeInBits(VT));
	if (isTypeLegal(intVT)) {
		... use it ...

or, if you are happy to use illegal integers (but not apints):
	...
	if (!MVT::isExtendedVT(IntVT)) {
		... use it ...

You tried to explain before but I didn't get it.

Ciao,

Duncan.
