plct的rvv-iscas分支很久没有开发，可以尝试使用upstream编译rvv intrinsic程序，upstream仓库： https://github.com/llvm/llvm-project

安装好llvm upstream仓库以后，重新编译过以前成功的代码，出现版本错误
clang-14: error: invalid arch name 'rv64gcv1p0', unsupported version number 1.0 for experimental extension 'v'(this compiler supports 0.10)
安装流程

$ git clone https://github.com/llvm/llvm-project.git
$ cd llvm-project
$ mkdir build
$ cd build
$ cmake -DLLVM_TARGETS_TO_BUILD="RISCV" -DLLVM_ENABLE_PROJECTS="clang" -DLLVM_USE_LINKER=gold -G Ninja ../llvm
$ ninja
$ sudo cmake --build . --target install

是的，upstream的rvv版本是0.10版本，使用rv64gcv0p10编译。对comment1中测试程序应该可以正常编译

看起来你应该把参数改为 rv64gcv1p0

- clang --target=riscv64-unknown-elf -march=rv64gcv0p10 ...
+ clang --target=riscv64-unknown-elf -march=rv64gcv1p0 ...
