URL: https://github.com/llvm/llvm-project/commit/0e3e0bf42c25b280d8caa455c6ae7e4a04d3667a DIFF: https://github.com/llvm/llvm-project/commit/0e3e0bf42c25b280d8caa455c6ae7e4a04d3667a.diff LOG: [RISCV] Add processor definition for XiangShan-KunMingHu-V2R2 (#123193) XiangShan-KunMingHu is the third generation of Open-source high-performance RISC-V processor developed by Beijing Institute of Open Source Chip (BOSC) , and its latest version is V2R2. The KunMingHu manual is now available at https://github.com/OpenXiangShan/XiangShan-User-Guide/releases. It will be updated on the official XiangShan documentation site: https://docs.xiangshan.cc/zh-cn/latest You can find the corresponding ISA extension from the XiangShan Github repository: https://github.com/OpenXiangShan/XiangShan/blob/master/src/main/scala/xiangshan/Parameters.scala If you want to track the latest performance data of KunMingHu, please check XiangShan Biweekly: https://docs.xiangshan.cc/zh-cn/latest/blog This PR adds the processor definition for KunMingHu V2R2, developed by the XSCC team https://github.com/orgs/OpenXiangShan/teams/xscc. The scheduling model for XiangShan-KunMingHu V2R2 will be submitted in a subsequent PR. --------- Co-authored-by: Shenglin Tang <tangsheng...@ict.ac.cn> Co-authored-by: Xu, Zefan
