Do we still use TBAA for the original motivating reason for adding it,
e.g.,:
void f(float *f, int *n) {
for (int i = 0; i < *n; ++i) {
f[i] *= 2;
}
}
where here you want to know that "f[i]" does not modify "*n"?
(Yes, that code is kinda hokey, in that real-world code would probably
not pass n by-reference, but of course this happens with structures and
such...)
