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.

WebThis __attribute__ ( (aligned (16))) is indeed useful (on x86-64) for vector instructions like SSE3 or AVX, since it is aligning to 16 bytes your a array. It should enable the optimizing compiler to generate more efficient machine code. (You probably need also to give some optimization flags like -mtune=native -O3 to gcc ). WebHowever, again, the compiler is aware of the alignment constraints and will generate extra instructions to perform the memory access in a way that does not cause unaligned access. Of course, the extra instructions obviously cause a loss in performance compared to the non-packed case, so the packed attribute should only be used when avoiding ...
