[PATCH] D28508: [NVPTX] Implement NVPTXTargetLowering::getSqrtEstimate.

[Justin Lebar via Phabricator via llvm-commits]

jlebar added a comment.

Looking through this code, we don't even parse the mrecip string properly.  For example, `all,!sqrt` should enable reciprocal approximations for everything other than sqrt, but as I read TargetLoweringBase::getOpEnabled, it enables it for nothing.  :(
