Bjarke Hammersholt Roune c5853844e0 [SCEV] Apply NSW and NUW flags via poison value analysis for sub, mul and shl ... Summary: http://reviews.llvm.org/D11212 made Scalar Evolution able to propagate NSW and NUW flags from instructions to SCEVs for add instructions. This patch expands that to sub, mul and shl instructions. This change makes LSR able to generate pointer induction variables for loops like these, where the index is 32 bit and the pointer is 64 bit: for (int i = 0; i < numIterations; ++i) sum += ptr[i - offset]; for (int i = 0; i < numIterations; ++i) sum += ptr[i * stride]; for (int i = 0; i < numIterations; ++i) sum += ptr[3 * (i << 7)]; Reviewers: atrick, sanjoy Subscribers: sanjoy, majnemer, hfinkel, llvm-commits, meheff, jingyue, eliben Differential Revision: http://reviews.llvm.org/D11860 llvm-svn: 245118		2015-08-14 22:45:26 +00:00
