-// FIXME: Select directly to _e32 so we don't need to deal with modifiers.
 // FIXME: We can't re-use SelectionDAG patterns here because they match
 // against a custom SDNode and we would need to create a generic machine
 // instruction that is equivalent to the custom SDNode.  This would also require
 // us to custom legalize the intrinsic to the new generic machine instruction,
 // but I can't get custom legalizing of intrinsic to work and I'm not sure if
 // this is even supported yet.
