@sscalpone @mstorsjo thanks for sharing the additional test cases, in some cases we cannot yet convert all hoisted recipes to single-scalar VPReplicateRecipes after hoisting. Should be fixed by making sure we also unroll all VPReplicateRecipes outside the loop region by VF: 19495364949476df196e3a0a12b3a035f7c2d1be
