Can someone tell me why clang report a warning here? isn't lludump.a a type of "unsigned long long"? Thanks.
#include <stdio.h>
typedef unsigned char u8;
typedef unsigned char u08;
typedef unsigned short u16;
typedef unsigned int u32;
typedef unsigned long long u64;
struct llu_dump_test {
u64 a : 4;
u64 b : 56;
u64 c : 4;
};
int main() {
struct llu_dump_test lludump;
printf("%llu\n", lludump.a);
return 0;
}
bpang@US-BPANG:~$ clang -c e.c
e.c:18:20: warning: format specifies type 'unsigned long long' but the argument has type 'int' [-Wformat]
printf("%llu\n", lludump.a);
