WebThe aligned attribute can only increase the alignment; but you can decrease it by specifying packed as well. See below. Note that the effectiveness of aligned attributes may be limited by inherent limitations in your linker. On many systems, the linker is only able to arrange for variables to be aligned up to a certain maximum alignment.

WebJul 23, 2024 · I take your point, although there seems to be a slight problem with your example. In your code, `&a->record.data[0]` is not a well-aligned access, because `struct attribute` is defined as packed, so compiler has no any information about where `a` itself is aligned to. `a` could start at any address so `a->record.data` might not well-aligned. pantagis buffet menu
