[PATCH] D143074: [LangRef] improve documentation of SNaN in the default FP environment

[Ralf via Phabricator via llvm-commits]

RalfJung added a comment.

"undefined" is a dangerous word. I hope you didn't mean that it is literally `undef`.

Also, it's not exceptions that are cleared, it's the sNaN bit, right? So you might want to keep the original sentence about exceptions, and then add a new one saying
"There is also no attempt to treat the signaling bit as specified by IEEE-754; in particular, arithmetic operations can produce signaling NaNs."
