[riscv] How do I use the RISC-V Vector extension instructions in LLVM IR?
Hi Everyone, I am wondering how to use RISC-V V (Vector) extension instructions in LLVM IR. In 2019 Kruppe and Espasa gave a talk [1] overviewing the Vector extension and on slide 16 [2] they show LLVM IR samples which use the vector instructions through intrinsic functions, such as: %vl = call i32 @llvm.riscv.vsetvl(i32 %n) At the time of the talk (April 2019) LLVM support for the V
