Hi Sylvestre,
I think you are missing revision 195971.
https://llvm.org/viewvc/llvm-project?view=revision&revision=195971
That revision changed some tests (all the tests that are failing for
you) introducing a specific -mcpu flag to constraint the instruction
selection.
For example, test vec_shift4.ll has been modified by r195971
introducing flag '-mcpu=corei7'.
In your case, test vec_shift4.ll fails because it finds an unexpected
' vpsllvd' instead of 'pslld'. ' vpsllvd' is AVX2 (which might imply
that your host is probably AVX2).
In conclusion, in my opinion if you integrate r195971 then all the
failures should disappear.
Cheers,
Andrea
