[PATCH] D47332: [PowerPC] Exploit the vector min/max instructions

[Nemanja Ivanovic via Phabricator via llvm-commits]

nemanjai added a comment.

Updated to remove the patterns for the Altivec versions of vector min/max as they have IEEE semantics wrt. handling NaN. A subsequent patch will legalize the `_IEEE` versions of the nodes for single precision and provide patterns to match them to `vmaxfp/vminfp`.
