Hi All, I have a problem with VectorLegalizer::ExpandStore() with v4i1. Let's see a example. * LLVM IR store <4 x i1> %edgeMask_for.body1314, <4 x i1>* %27 * SelectionDAG before vector legalization ch = store<ST1[%16](align=4), trunc to v4i1> t0, t128, t32, undef:i64 * SelectionDAG after vector legalization ch = store<ST1[%16]...
