- Add devel/dwz: DWARF optimization and duplicate removal tool
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.
