[PATCH] D64099: [InstCombine] pow(C,x) -> exp2(log2(C)*x)

[Evandro Menezes via Phabricator via llvm-commits]

evandro added a comment.

Since using `exp2(log())` was mathematically incorrect, have you run any benchmark that validates the results, such SPEC CPU2006 or CPU2017?  If so, what kind of improvement did it register?
