Summary: This change merges adjacent 32 bit zero stores into a 64 bit zero store. e.g., str wzr, [x0] str wzr, [x0, #4] becomes str xzr, [x0] Therefore, four adjacent 32 bit zero stores will be a single stp. e.g., str wzr, [x0] str wzr, [x0, #4] str wzr, [x0, #8] str wzr, [x0, #12] becomes stp xzr, xzr, [x0] Reviewers: mcrosier, jmolloy, gberry, t.p.northover Subscribers: aemerson, rengolin, mcrosier, llvm-commits Differential Revision: http://reviews.llvm.org/D16933 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@260682 91177308-0d34-0410-b5e6-96231b3b80d8
