Summary: This patch adds the following SVE intrinsics for scatter stores: * 64-bit offsets: * @llvm.aarch64.sve.st1.scatter (unscaled) * @llvm.aarch64.sve.st1.scatter.index (scaled) * 32-bit unscaled offsets: * @llvm.aarch64.sve.st1.scatter.uxtw (zero-extended offset) * @llvm.aarch64.sve.st1.scatter.sxtw (sign-extended-offset) * 32-bit scaled offsets: * @llvm.aarch64.sve.st1.scatter.uxtw.index (zero-extended offset) * @llvm.aarch64.sve.st1.scatter.sxtw.index (sign-extended offset) * vector base + immediate: * @llvm.aarch64.sve.st1.scatter.imm Reviewers: rengolin, efriedma, sdesmalen Reviewed By: efriedma, sdesmalen Subscribers: kmclaughlin, eli.friedman, tschuett, kristof.beyls, hiraditya, rkruppe, psnobl, llvm-commits Tags: #llvm Differential Revision: https://reviews.llvm.org/D71074
