[libcxx-commits] [PATCH] D84200: Disable trivial weak_ptr test on ARM because it is not expected to work.

[James Y Knight via Phabricator via libcxx-commits]

jyknight added a comment.

Right, the trivial_abi attribute doesn't guarantee that you pass an object in registers, it just gives permission for the implementation to treat the struct as-if it was a trivial struct. On ARM32, since the ABI specifies that trivial structs > 4 bytes are returned indirectly by passing a hidden pointer to a pre-allocated return struct, that's what you get.
