[PATCH] D157836: [RFC][IR] Correct lowering of `f128` intrinsics

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

clang knows the layout of "long double", but we don't explicitly pass it down to LLVM.  I don't think it's something we've ever needed to care about; e.g. compiler-rt routines use different names for f80 vs. f128.

Not sure exactly what the design of that would look like off the top of my head; maybe something involving a module attribute.
