[PATCH] D101209: [PowerPC] Provide fastmath sqrt and div functions in altivec.h

[Nemanja Ivanovic via Phabricator via cfe-commits]

nemanjai added a comment.

Changed `rsqrt` to be an actual reciprocal rather than just a refined `sqrt` estimate.

I have verified that the code generated is equivalent to gcc's and the results produced are the same.
