Bug ID: 30258 Summary: [SLP][AArch64] Implement cost model for intrinsics. Product: libraries Version: trunk Hardware: PC OS: Windows NT Status: NEW Severity: normal Priority: P Component: Backend: AArch64 Assignee: unassignedb...@nondot.org Reporter: mcros...@codeaurora.org CC: bma...@codeaurora.org, llvm-bugs@lists.llvm.org Classification: Unclassified In r270537, Simon added the framework for an intrinsic cost model in the X86 backend. We should consider doing the same for AArch64 as this may expose opportunities in the SLP vectorizer. Currently, X86 supports bitreverse, bswap, ctlz, ctpop, and cttz. I want to say AArch64 has support for most of these in vector form. However, I don't know how well the AArch64 backend handles the lowering of these intrinsics. -- You are receiving this mail because: You are on the CC list for the bug.
