Bug ID: 64821
Summary: [AArch64] Improve target folding for vsqrt_f64
intrinsic
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Keywords: missed-optimization
Severity: minor
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: ktkachov at gcc dot gnu.org
Following the implementation of vsqrt_f64 with a target builtin:
https://gcc.gnu.org/ml/gcc-patches/2015-01/msg00699.html
it was suggested to add some target folding code into a sqrt when
-fno-math-errno is given:
https://gcc.gnu.org/ml/gcc-patches/2015-01/msg00710.html
This issue tracks that work that should be done for GCC 6
