--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> --- The Simple Location Description before each DW_OP_{,bit_}piece may be empty, that is the DWARF 5 2.6.1.1.1 Empty Location Descriptions. Sorry for my wording issue earlier, where I wrote Single I meant Simple. Single Location Description is either a simple or composite location description.
