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.
