We've had the testcase below in autovect-branch for a while, testing that the 3 loops get vectorized. On mainline the third loop now gets eliminated by DCE (.t44.dce3). Not sure I understand why... isn't the print loop enough to keep it alive?

It should be but from the looks of it. For some reason in alias2, we don't say D.503_30 points to anyoffset in &e unlike before. You might be able to generate a C testcase for this too.

Can you also file a bug?

Thanks,
