Yes, you need to support the .dwsect pseudo (which is basically a dedicated pseudo like .section, but also includes section length). But note that .dwsect only allows a subset of all dwarf sections. > AFAICT, for gcc+gas it should already work with binutils that include > the AdaCore patch for DWARF support.
