Supporting scalable vector ISA such as ARM SVE, RISC-V Vector is a hot topic in LLVM. In this talk, we will introduce the scalable vector ISA in "SX-Aurora TSUBASA" vector computer that is only one market available computer on which the LLVM developers can play with scalable vector. The scalar LLVM backend for SX-Aurora is available, and developers can immediately try interesting topics such as design of IR and auto vectorization. We will also describe design of vector IR based on LLVM-VP and code generation technique for it.
