-Implement Newton-Rhapson method for improving estimate instructions to the
-correct accuracy, and implementing divide as multiply by reciprocal when it has
-more than one use. Itanium would want this too.

Compile offsets from allocas:
int *%test() {

-Complete the signed i32 to FP conversion code using 64-bit registers
-transformation, good for PI. See PPCISelLowering.cpp, this comment:
-
- // FIXME: disable this lowered code. This generates 64-bit register values,
- // and we don't model the fact that the top part is clobbered by calls. We
- // need to flag these together so that the value isn't live across a call.
- //setOperationAction(ISD::SINT_TO_FP, MVT::i32, Custom);
-
-Also, if the registers are spilled to the stack, we have to ensure that all
-64-bits of them are save/restored, otherwise we will miscompile the code. It
-sounds like we need to get the 64-bit register classes going.
