[PATCH] D87528: Enable '#pragma STDC FENV_ACCESS' in frontend cf. D69272 - Work in Progress

[John McCall via Phabricator via cfe-commits]

rjmccall added a comment.

IRGen generally doesn't query the AST constant evaluator for arbitrary expressions; we do it for certain calls and loads because otherwise we might emit an illegal ODR-use, but otherwise we just expect LLVM's constant-folding to do a decent job.
