No problem! I've moved the tests into `fullfp16.c` and I deleted the tests in [https://github.com/llvm/llvm-project/blob/8d7823ea8f40cf5df1c623018bf9c0a308fa4a36/clang/test/CodeGen/AArch64/v8.2a-fp16-intrinsics.c](https://github.com/llvm/llvm-project/blob/8d7823ea8f40cf5df1c623018bf9c0a308fa4a36/clang/test/CodeGen/AArch64/v8.2a-fp16-intrinsics.c). Should I be removing the ones in [https://github.com/llvm/llvm-project/blob/8d7823ea8f40cf5df1c623018bf9c0a308fa4a36/clang/test/CodeGen/AArch64/v8.2a-fp16-intrinsics-constrained.c](https://github.com/llvm/llvm-project/blob/8d7823ea8f40cf5df1c623018bf9c0a308fa4a36/clang/test/CodeGen/AArch64/v8.2a-fp16-intrinsics-constrained.c) as well?
