Now, back to PR53970, where #pragma pack() is used to pack a
struct. With #pragma pack() no part of the type or field-decls
have a hint that packing took place (well, their align information
tell you), which means the vectorizers use of contains_packed_reference
is not conservative enough,
I've arrived at get_object_{or_type,}alignment again looking at
PR53970. And I finally concluded we should unconditionally relying
on type-alignment on INDIRECT/MEM/TARGET_MEM_REF when we ask for
the alignment of an access (as opposed to when asking for the
alignment of an address). So the
