Hello, I was hoping to get some clarification on the aim of the GVN pass. I have been reading a bit about global value numbering, and from what I understand, there are polynomial time algorithms for removing duplicate computations from loops[1]. I have an example program[2] which computes the sum of an array twice, in two separate accumulators. Here, sum0 and sum1 are both sums of the array A.
