--- Comment #5 from Richard Biener <rguenth at gcc dot gnu.org> ---
I think we use a wrong ELSE value:
vect_b.19_54 = VIEW_CONVERT_EXPR<vector([4,4]) signed int>(vect_b_lsm.18_53);
vect__15.20_56 = .COND_ADD (loop_mask_55, { -1, ... }, vect_b.19_54, { -1,
... });
^^^
vect__8.21_57 = .COND_SUB (loop_mask_55, vect__15.20_56, vect__5.17_51,
vect__15.20_56);
vect__9.22_58 = VIEW_CONVERT_EXPR<vector([4,4]) unsigned int>(vect__8.21_57);
I'll see how that happens. Possibly an operand order issue.
