node. If the target doesn't mark ISD::FSQRT as Legal or Custom then
ExpandNode in LegalizeDAG.cpp turns it back into a sqrtf libcall.

Ah. Yes, that would explain it... does this mean that I can rely on all
the intrinsics listed existing for the common types (int, float,
double)? Or should I be trying to follow the libc call route?
I've noticed that llc is successfully
