Huihui Zhang 4626613ffe [InstCombine] Fold icmp eq/ne (and %x, C), 0 iff (-C) is power of two -> %x u</u>= (-C) earlier. ... Summary: To generate simplified IR, make sure fold (X & ~C) ==/!= 0 --> X u</u>= C+1 is scheduled before fold ((X << Y) & C) == 0 -> (X & (C >> Y)) == 0. https://rise4fun.com/Alive/7ZN Reviewers: lebedev.ri, efriedma, spatel, craig.topper Reviewed By: lebedev.ri Subscribers: hiraditya, llvm-commits Tags: #llvm Differential Revision: https://reviews.llvm.org/D63505 llvm-svn: 364255		2019-06-25 00:09:10 +00:00
