GCC test cases for the Neoverse V2 CPU’s compare-and-conditional-select (CMP+CSEL) macro-fusion have been updated to accept alternative conditional polarities. This change prevents the tests from breaking due to unrelated middle-end modifications that alter control flow graph shapes, ensuring the tests focus on the actual macro-fusion behaviour.
