--- Comment #2 from zhongyunde at tom dot com <zhongyunde at tom dot com> --- should the data alignment honor the user specified ? Now, it seems compiler _do_ align the initializer according align load. so even if the local array doesn't specify the __attribute__((aligned(64))), it still align to 64 bytes.
