           Summary: [12 Regression] Recent vectorizer testsuite
                    regressions on x86
           Product: gcc

            Status: UNCONFIRMED
          Severity: normal

None of this was present when I bootstrapped/regtested 24 hours ago with
r12-6420 reverted.
If I revert r12-6523 and r12-6420 on current trunk, then all these pass again.

It seems to be fixed on latest trunk, or maybe latent?

That was PR 103971 I think.

The issue is likely the same as in PR103997, I've commented there.
