--- Comment #16 from Ramana Radhakrishnan <ramana at gcc dot gnu.org> --- (In reply to Jakub Jelinek from comment #10) > aarch64_function_arg_alignment > has: > for (tree field = TYPE_FIELDS (type); field; field = DECL_CHAIN (field)) > alignment = std::max (alignment, DECL_ALIGN (field)); > and thus has similar problem (no testcases in this case though). A prototype fix (needs tidying up for sure!) that warns for aarch64 is as attached. There are no regressions on a full bootstrap and test run. I would be grateful for any comments. Note that I haven't managed to actually trigger an ABI warning because of this on aarch64. Note that this is dependent on clarification with respect to the AAPCS . I'm not yet happy with the amount of refactoring we have to do to get the warnings on ARM. regards Ramana
