LGTM. Anything else would be wondering if it can be merged/genericised with Arm somehow but that's not a blocker.



================
Comment at: clang/include/clang/Basic/AttrDocs.td:2141
+in RVV builtins, and still be recognized as clang builtins equivalent to the
+underlying name. For example, ``riscv_vector.h`` declares the function ``vget`` with
+``__attribute__((__clang_riscv_builtin_alias(__builtin_rvv_vget_i8mf8x2_i8mf8)))``.
