The DOM (Dominator Tree) analysis pass has removed its simplify_binary_operation method. This functionality is now handled more effectively by the ranger pass, which specializes in value range analysis. The change streamlines the DOM pass by offloading this task. New test cases were added to ensure that the compiler’s ability to handle these operations is preserved. Testing on a benchmark suite showed no regressions.
