[PATCH] D66236: [SDAG][x86] check for relaxed math when matching an FP reduction

[Craig Topper via Phabricator via llvm-commits]

craig.topper added inline comments.


================
Comment at: llvm/lib/Target/X86/X86ISelLowering.cpp:35487
 
   unsigned HorizOpcode = Opc == ISD::ADD ? X86ISD::HADD : X86ISD::FHADD;
 
----------------
So was the FP part of this just unusable before now?
