I don't think we need to wait until the document is public, necessarily. The entire AArch64 backend went in before the encodings were public outside ARM (except maybe in binutils source?) and releasing specifications with no implementation yet is a bit annoying too. We may discover bugs (though this seems fairly straightforward), but I think it's highly unlikely we'll have vocal and powerful enough users of such a niche feature to prevent us fixing them. I agree about the asm tests though, they belong in LLVM. ================ Comment at: include/clang/Basic/BuiltinsARM.def:55 @@ -54,3 +54,3 @@ BUILTIN(__builtin_arm_mrc2, "UiUIiUIiUIiUIiUIi", "") -BUILTIN(__builtin_arm_cdp, "vUiUiUiUiUiUi", "") -BUILTIN(__builtin_arm_cdp2, "vUiUiUiUiUiUi", "") +BUILTIN(__builtin_arm_cdp, "vUIiUIiUIiUIiUIiUIi", "") +BUILTIN(__builtin_arm_cdp2, "vUIiUIiUIiUIiUIiUIi", "") ---------------- rengolin wrote: > I wonder why the old signature was wrong... probably because the docs weren't > public and no one could really check whether they were right or not.
