Chapter 6. dwz

dwz is a command line tool that attempts to optimize DWARF debugging information contained in ELF shared libraries and ELF executables for size. To do so, dwz replaces DWARF information representation with equivalent smaller representation where possible and reduces the amount of duplication by using techniques from Appendix E of the DWARF Standard.
Red Hat Developer Toolset is distributed with dwz 0.12.

In Red Hat Developer Toolset, the dwz utility is provided by the devtoolset-4-dwz package and is automatically installed with devtoolset-4-toolchain as described in Section 1.5, “Installing Red Hat Developer Toolset”.
