fprintf: When expanding types do it for union typedefs as well
For instance:
$ pahole xfrm_address_t
typedef union xfrm_address_t;
$
Is completely broken, xfrm_address_t is an "inline" union, this patch
fixes it:
$ pahole xfrm_address_t
typedef union {
__be32 a4; /* 0 4 */
__be32 a6[4]; /* 0 16 */
struct in6_addr in6; /* 0 16 */
} xfrm_address_t;
$
Expansion also now works:
$ pahole -E xfrm_address_t
typedef union {
/* typedef __be32 -> __u32 */ unsigned int a4; /* 0 4 */
/* typedef __be32 -> __u32 */ unsigned int a6[4]; /* 0 16 */
struct in6_addr {
union {
/* typedef __u8 */ unsigned char u6_addr8[16]; /* 0 16 */
/* typedef __be16 -> __u16 */ short unsigned int u6_addr16[8]; /* 0 16 */
/* typedef __be32 -> __u32 */ unsigned int u6_addr32[4]; /* 0 16 */
} in6_u; /* 0 16 */
} in6; /* 0 16 */
} xfrm_address_t;
$
And with a named union typedef:
$ pahole sigval_t
typedef union sigval sigval_t;
$ pahole -E sigval_t
typedef union sigval {
int sival_int; /* 0 4 */
void * sival_ptr; /* 0 8 */
} sigval_t;
