[PATCH] D49978: LangRef: Clarify expected sNaN behavior for minnum/maxnum

[Hal Finkel via Phabricator via llvm-commits]

hfinkel added inline comments.


================
Comment at: docs/LangRef.rst:11486
+the intrinsic lowering is responsible for quieting the inputs to get
+correct behavior (e.g. by using the equivalent of ``llvm.canonicalize``).
+
----------------
I don't understand this text because it seems like if the standard says that a QNaN is returned if either input is a SNaN, then why would the lowering need to additionally canonicalize the inputs? It seems like that would not change the result.
