Thanks Robin. The failures of FAIL: gcc.dg/vect/vect-strided-a-u8-i2-gap.c -flto -ffat-lto-objects (test for excess errors) from the linux-rv64gcv-lp64d testsuite log should not be a real failure (build failure but run success).
It passed locally as below, so will commit it soon.

There will be two cases for the combine: Jeff has already pre-acked this so it's good to go. I'm seeing a few failures in the CI, though. Could you check if they're real? -- Regards Robin
