[PATCH] D92080: [Clang] Mutate long-double math builtins into f128 under IEEE-quad

[Craig Topper via Phabricator via cfe-commits]

craig.topper added a comment.

I don't think I understand the whole picture here. Why would only builtins get mutated? Does a call to "modf" still call "modf"? But __builtin_modf will call modf128? Is there a corresponding patch to the runtime libcalls table in the backend? With -ffast-math __builtin_sinl becomes llvm.sin.f128 and the backend will emit a call to sinl if ISD::SIN isn't legal.
