%description
|
||||
The dwz package contains 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.
