non-deterministic things like the ordering of blocks in the dominance frontier of a BB. Unfortunately, I don't know of a better way to solve this problem than to explicitly sort the BB's in function-order before processing them. This is guaranteed to slow the pass down a bit, but is absolutely necessary to get usable diffs between two different tools executing the mem2reg or scalarrepl pass. Before this, bazillions of spurious diff failures occurred all over the place due to the different order of processing PHIs: - %tmp.111 = getelementptr %struct.Connector_struct* %upcon.0.0, uint 0, uint 0 + %tmp.111 = getelementptr %struct.Connector_struct* %upcon.0.1, uint 0, uint 0 Now, the diffs match. llvm-svn: 14244
