43 * Vector types
44 *
45 * Note: OpenCL requires that all types be naturally aligned.
46 * This means that vector types must be naturally aligned.
47 * For example, a vector of four floats must be aligned to
48 * a 16 byte boundary (calculated as 4 * the natural 4-byte
49 * alignment of the float). The alignment qualifiers here
50 * will only function properly if your compiler supports them
51 * and if you don't actively work to defeat them. For example,
52 * in order for a cl_float4 to be 16 byte aligned in a struct,
53 * the start of the struct must itself be 16-byte aligned.
54 *
55 * Maintaining proper alignment is the user's responsibility.
