Jingyue Wu 439d17ca9f [SLSR] handle candidate form &B[i * S] ... Summary: This patch enhances SLSR to handle another candidate form &B[i * S]. If we found two candidates S1: X = &B[i * S] S2: Y = &B[i' * S] and S1 dominates S2, we can replace S2 with Y = &X[(i' - i) * S] Test Plan: slsr-gep.ll X86/no-slsr.ll: verify that we do not run SLSR on GEPs that already fit into an addressing mode Reviewers: eliben, atrick, meheff, hfinkel Reviewed By: hfinkel Subscribers: sanjoy, llvm-commits Differential Revision: http://reviews.llvm.org/D7459 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@233286 91177308-0d34-0410-b5e6-96231b3b80d8		2015-03-26 16:49:24 +00:00
