Mehdi Amini 4c8f5afd99 InstCombine: fix fold "fcmp x, undef" to account for NaN ... Summary: See the two test cases. ; Can fold fcmp with undef on one side by choosing NaN for the undef ; Can fold fcmp with undef on both side ; fcmp u_pred undef, undef -> true ; fcmp o_pred undef, undef -> false ; because whatever you choose for the first undef ; you can choose NaN for the other undef Reviewers: hfinkel, chandlerc, majnemer Reviewed By: majnemer Subscribers: majnemer, llvm-commits Differential Revision: http://reviews.llvm.org/D7617 From: Mehdi Amini <mehdi.amini@apple.com> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@231626 91177308-0d34-0410-b5e6-96231b3b80d8		2015-03-09 03:20:25 +00:00
