[PATCH] D67300: [ConstantFolding] Fold constant calls to log2()

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

I think a few of the functions we use ConstantFoldFP with actually already have implementations in APFloat: floor, ceil, round, fabs, fmod.

I'm not sure "C99" is really relevant; I don't think we support any hosts which don't have C99 libm, anyway.
