Can we support anonymouse struct?

bpang@US-BPANG:~/dwarves/build$ cat t.c
typedef struct {
int x;
int y;
} xy;
int main(){
   xy xy0;
}
bpang@US-BPANG:~/dwarves/build$ gcc -g t.c
bpang@US-BPANG:~/dwarves/build$ ./pahole -C xy -s a.out
xy      0       0

It shows 0 for xy's size, I am expecting it can show the correct size 8.

seems to be a bug specific to the size_formatter; we can dump the typedef fine:

$ pahole -C xy a.out
typedef struct {
int x; /* 0 4 /
int y; / 4 4 */

/* size: 8, cachelines: 1, members: 2 */
/* last cacheline: 8 bytes */

} xy;

...and changing to a struct, we get the right size. Investigating..

seems to be a general issue for typedefs, not just anon ones; following gives 0 size too:

struct xys {
int x;
int y;
};

typedef struct xys xy;
int main(){
xy xy0;
}
