devel/dwz 0.14_1 DragonFly

dwz is a program that attempts to optimize DWARF debugging information contained in ELF shared libraries and ELF executables for size, by replacing DWARF information representation with equivalent smaller representation where possible and by reducing the amount of duplication using techniques from DWARF standard appendix E - creating DW_TAG_partial_unit compilation units (CUs) for duplicated information and using DW_TAG_imported_unit to import it into each CU that needs it.
