--- Comment #5 from Richard Biener <rguenth at gcc dot gnu.org> ---
Err, abs(A) < sqrt (B) isn't handled yet, no? Though I'm not sure if it's wise
to emit A * A < B for that given A * A is going to drop of quite some bits in
precision and likeliness to overflow / underflow to +Inf / denormal is high.
