1. You can download at https://xuantie.t-head.cn/community/download?id=4168444414324183040
2. clang on csky depends to gcc runtime so it needs gcc toolchain, you can download at https://xuantie.t-head.cn/community/download?id=3854599713706024960
3. Sorry about no document to describe the run process of llvm-test-suite in csky. But there is llvm build bot you can refer to. https://lab.llvm.org/staging/#/builders/215/builds/2795
