--- Comment #4 from Aldy Hernandez <aldyh at gcc dot gnu.org> --- (In reply to Richard Biener from comment #3) > Yeah, I think these kind of testsuite changes are no good. The loop threading restrictions disallow a couple jump threads (rotating the loop and crossing the loop header without exiting the loop). The test was depending on these invalid threads to trigger the "optimized: basic block" diagnostic. Jeff suggested manually rotating the loop to continue testing the SLP functionality. Is there something else we could do?
