[PATCH] D156506: [clang][Interp] Check floating results for NaNs

[Timm Bäder via Phabricator via cfe-commits]

tbaeder added inline comments.


================
Comment at: clang/lib/AST/Interp/Interp.cpp:503
+  //   If during the evaluation of an expression, the result is not
+  //   mathematically defined [...], the behavior is undefined.
+  // FIXME: C++ rules require us to not conform to IEEE 754 here.
----------------
@jcranmer-intel Doesn't this comment (which I've coped from `ExprConstant.cpp`) contradict what you said about not checking the result?
