-Follow the [Environment Setup Guide for MLIR and RVV Testing and Experiments](https://github.com/buddy-compiler/buddy-mlir/blob/main/docs/RVVEnvironment.md) to prepare the RVV environment. Furthermore, To enable the openmp feature on RISC-V, you also need to refer to [Prepare RISC-V OpenMP ToolChain](https://github.com/buddy-compiler/buddy-benchmark/blob/main/docs/PrepareRVOpenMP.md).
