[PATCH] D134136: [Clang] Support constexpr for builtin fmax, fmin, ilogb, logb, scalbn

[Eli Friedman via Phabricator via cfe-commits]

These patches are hard to review, yes; the reviewer has to go through and verify for each function that the substitutes you've written actually match the C library semantics.  (It's very easy to make mistakes with that sort of thing.)

On that front, I'm pretty sure the NaN handling in your fmin/fmax implementations are wrong.
