================
Comment at: llvm/docs/LangRef.rst:1828-1831
+   be flushed to zero by standard floating point operations. It is not
+   mandated that flushing to zero occurs, but if a subnormal output is
+   flushed to zero, it must respect the sign mode. Not all targets
+   support all modes.
----------------
On second thought I think this may be too permissive. I think based on the use in DAGCombiner, that flushing of outputs is compulsory.
