I should note the better testcase is:
typedef __SIZE_TYPE__ size_t;
typedef struct {
size_t car;
size_t cdr;
} cons;
int g(void);
size_t f(size_t a)
{
size_t x;
size_t *d;
size_t i;
d = &x;
while ( (i = g()) != 0)
{
if (i >= 30)
d = &((cons*)i)->car;
}
*d = 1;
}
The previous passes on 20050705 because of constant prop.
