For
#include <stdint.h>
struct a {
unsigned a:1;
unsigned b:1;
unsigned c:1;
};
struct b {
uint8_t a:1;
uint8_t b:1;
uint8_t c:1;
};
void f(struct a a, struct b b) {}
pahole says:
struct a {
unsigned int a:1; /* 0:31 4 */
unsigned int b:1; /* 0:30 4 */
unsigned int c:1; /* 0:29 4 */
/* size: 4, cachelines: 1, members: 3 */
/* bit_padding: 29 bits */
/* last cacheline: 4 bytes */
};
struct b {
uint8_t a:1; /* 0: 7 1 */
uint8_t b:1; /* 0: 6 1 */
uint8_t c:1; /* 0: 5 1 */
/* size: 1, cachelines: 1, members: 3 */
/* bit_padding: 5 bits */
/* last cacheline: 1 bytes */
};
I initially used unsigned, but I noticed this.
