Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org, | |rguenth at gcc dot gnu.org --- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Bet if BIT_FIELD_REF in the middle aren't allowed gimplify_compound_lval could at least for the non-lvalue case stop walk on BIT_FIELD_REF that isn't the outermost. But I have no idea what to do if it is lvalue, i.e. if we want e.g. VIEW_CONVERT_EXPR <type, BIT_FIELD_REF <var, x, y>> on the lhs.
