I got
# cat x.c
#include <ia64intrin.h>
int
foo (long **x, long *i)
{
return __sync_bool_compare_and_swap (x, 0L, i);
}
# gcc -Wall x.c -c
x.c: In function `foo':
x.c:6: warning: cast from pointer to integer of different size
x.c:6: warning: cast to pointer from integer of different size
x.c:6: warning: return makes integer from pointer without a cast
I have 2 questions:
1. According to my ia64 psABI, __sync_bool_compare_and_swap should
return int. But gcc's version doesn't.
2. Why do I got warnings about casting of different size?
