chill added inline comments.
================ Comment at: clang/test/CodeGen/aarch64-ABI-align-packed.c:34 struct aligned_member_8 { uint16x8_t M0 __attribute((aligned (8))); // member alignment 16 since __attribute((aligned (n))) sets the minimum alignment }; ---------------- JiruiWu wrote: > chill wrote: > > Don't you mean "`__attribute__((aligned(n)))` cannot decrease the minimum > > required alignment" ? > > > > > I added this comment to explain that the natural alignment of the struct > `aligned_member_8` is 16-byte instead of 8-byte. In this test case the > alignment of `M0` is 16 bytes, which is above the minimum required alignment > specified by `__attribute__((aligned(8)))`. Yes, so the `__attribute__` does not actually set the minimum required alignment, it sets the member alignment to the maximum of the natural and the specified alignment.
