[PATCH] D63038: [SimplifyLibCalls] powf(x, sitofp(n)) -> powi(x, n)

[Nikita Popov via Phabricator via llvm-commits]

nikic added a comment.

Can you please provide some more information under which circumstances `powf(x, (int) y)` will provide a different result than `powi(x, y)`, and which fast-math flags specifically are necessary to make that transform legal?
