--- Comment #23 from Jan Hubicka <hubicka at gcc dot gnu.org> --- The patch looks reasonable. We probably could hash the padding vectors at summary generation time to reduce WPA overhead, but that can be done incrementally next stage1. I however wonder if we really guarantee to copy the paddings everywhere else then the total scalarization part? (i.e. in all paths through the RTL expansion)
