The Ada front end can emit somewhat complicated DWARF expressions for the offset of a field. While working in this area I found that I needed DW_OP_rot (to implement a branch-free computation -- it looked more difficult to add support for branching); and DW_OP_neg and DW_OP_abs (just basic functionality).
