-- The attribute `target_version` in GCC is only supported for C++, not for C.
 - The set of features as indicated by the [mapping table](https://arm-software.github.io/acle/main/acle.html#mapping) differs in support between the two compilers.
-- LLVM supports mixing `target_version` with `target_clones` whereas GCC does not yet support this.
