But then there is no guarantee that ptr is aligned after the call.
char buf[32] __attribute__((aligned (32)));
int
foo (void)
{
void *ptr = buf + 1;
posix_memalign (&ptr, 32, -1);

This re-writes posix_memalign calls to
posix_memalign (ptr, align, size);
tem = *ptr;
tem = __builtin_assume_aligned (align);
*ptr = tem;
during CF lowering (yeah, ok ...) to make alignment info accessible
to SSA based analysis.
