While this is fine, it makes it hard to actually test. In RTL I disable scheduling and BB reordering to prevent this. But in GIMPLE there seems to be nothing I can do. __builtin_expect seems to have no impact on the change since I suspect this is happening during expand where conditions can be flipped regardless of probability during compare_and_branch. Since the mid-end has plenty of correctness tests, this weakens the backend tests to just check that a correct looking sequence is emitted. gcc/testsuite/ChangeLog: PR testsuite/113502 * gcc.target/aarch64/sve/vect-early-break-cbranch.c: Ignore exact branch. * gcc.target/aarch64/vect-early-break-cbranch.c: Likewise.
