Code examples

The following code example fails the check and will give a warning:

#include "example.h"

/* example.h
#include <stdint.h>
#include <stdalign.h>
*/
extern alignas (8) int32_t x; /* Non-compliant - not consistently explicit */
alignas (16) int32_t y; /* Compliant */

The following code example passes the check and will not give a warning about this issue:

#include "example.h"

/* example.h
#include <stdint.h>
#include <stdalign.h>
*/

alignas (16) int32_t x; /* Non-compliant - not consistently explicit */
alignas (16) int32_t y; /* Compliant */
