DWARF optimization and duplicate removal tool
|
|
The DWARF optimization and duplicate removal tool (DWZ) is a program that compresses DWARF debugging information. History The first version was announced in 2012. Functionality DWZ compresses DWARF debugging information in ELF executables and shared libraries. It compresses by rewriting the debugging information into smaller but equivalent debugging information. The tool has two main modes of operation: singlefile mode and multifile mode. Singlefile mode In this mode the scope of compression is a single file. DWZ compresses by analyzing commonalities between debugging information from different compilation units. Multifile mode In this mode the scope of compression is between several files. Debugging information that is common between different files can be factored out into a new file, the multifile. |
