So I've been narrowing down a very fun issue in our Burst compiler stack with respect to noalias support, and I've managed to basically boil this down to the following failure (see https://godbolt.org/z/-mdjPV<https://urldefense.proofpoint.com/v2/url?u=https-3A__godbolt.org_z_-2DmdjPV...

So I've been narrowing down a very fun issue in our Burst compiler stack
with respect to noalias support, and I've managed to basically boil this
down to the following failure (see https://godbolt.org/z/-mdjPV):

return *a + *b + *c;
}
int foo(int * x, int * y) {
return *x + *y + called(x, x, y);
}
int bar(int * x, int * y) {
