<pre>reductions are now supported by LoopInterchange
(<a href="https://reviews.llvm.org/rL346438">https://reviews.llvm.org/rL346438</a>)
It now interchanges the following loop
extern int Arr[1024][1024];
unsigned no_deps_interchange(unsigned k) {
unsigned sum = 0;
for (int i = 0; i < 1024; ++i)
for(int j = 0; j < 1024; ++j)
sum += Arr[j][i] + k;
return sum;
}
I've created a follow up ticket to support passing in unsigned **Arr: PR39594</pre>
