Jingyue Wu 30a21f9ce5 [SROA] Fold a PHI node if all its incoming values are the same ... Summary: Fixes PR20425. During slice building, if all of the incoming values of a PHI node are the same, replace the PHI node with the common value. This simplification makes alloca's used by PHI nodes easier to promote. Test Plan: Added three more tests in phi-and-select.ll Reviewers: nlewycky, eliben, meheff, chandlerc Reviewed By: chandlerc Subscribers: zinovy.nis, hfinkel, baldrick, llvm-commits Differential Revision: http://reviews.llvm.org/D4659 llvm-svn: 216299		2014-08-22 22:45:57 +00:00
