I didn't push this yet because it would have introduced an UNRESOLVED that my summary script didn't catch. Normally I go with just contrib/test_summary but that only filters out FAIL and XPASS. I should really be using compare_testsuite_log.py from riscv-gnu-toolchain/scripts.
It was caused by a typo: -/* { dg-final { scan-tree-dump-times "vectorizing stmts using SLP" 1 "slp" } } */ +/* { dg-final { scan-tree-dump-times "vectorizing stmts using SLP" 1 "slp2" } } */ Regards Robin
