--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
We have it
/* sqrt(sqrt(x)) -> pow(x,1/4). */
(simplify
(sqrts (sqrts @0))
(pows @0 { build_real (type, dconst_quarter ()); }))
but only for canonicalization, we then expand that as (sqrt (sqrt @0)) again.
What is it that it can be "compiled in faster way" to?
