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
 };

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)))`.
