void TargetLoweringBase::computeRegisterProperties

It seems like this routine is not allocating any memory and could just be called a second time.

Does anyone know if that is true?

I looked at a bunch of it but did not want to create a memory leak by calling it again if it was doing a "new" indirectly somewhere.

I've created a clearRegisterClasses method so that we can start all over.

Then I would add register classes again and call computeRegisterProperties.

This is so I can switch processor major modes on a function basis.



I suppose I could just assume it's not allocating memory and run valgrind and see if it's leaking there.
