[PATCH] D104440: [X86] Fix bug when X86 stackify pass handle one ArgFPRW.

[Craig Topper via Phabricator via llvm-commits]

craig.topper added a comment.

I did some more digging and it looks like ISD::UNDEF for X86 should be turned into ConstantFP<0> by LegalizeDAG. So I really need more information about how we got here.
