There was also a suggestion that we accept the corresponding
[[clang::trivial_abi]] spelling. I believe it can be done in a separate
patch.
It seems like when Clang adopts gnu:: attributes, they keep the gnu::
spelling; we might want to do the same for Clang attributes. That is,
support clang::trivial_abi and not add gnu::trivial_abi.
Though, e.g. for musttail we just added [[gnu::musttail]] and support
[[clang::musttail]] with the same meaning.
It seems to me that supporting gnu:: and clang:: with the same semantics
just complicates code portability; if the goal is to handle existing
code, that means supporting the existing spelling.
