--- Comment #11 from Jakub Jelinek <jakub at gcc dot gnu.org> 2011-05-07 06:15:23 UTC --- locstats program, the above URL just gives the repo. Not sure if it has been adjusted already for typed DWARF stack though, if not, perhaps for the testing you could temporarily disable generation of DW_OP_GNU_*_type and DW_OP_GNU_convert/DW_OP_GNU_reinterpret in mem_loc_descriptor, just return NULL.
