RHEA-2015:2038 - Product Enhancement Advisory

Topic

New devtoolset-4-dwz packages are now available as a part of Red Hat Developer
Toolset 4.0 for Red Hat Enterprise Linux.

Description

The dwz command-line utility attempts to optimize DWARF debugging information
contained in ELF shared libraries and ELF executables for size. It replaces
DWARF information representation with an equivalent smaller representation where
possible, and reduces the amount of duplication by using techniques from the
DWARF Standard, Appendix E. The devtoolset-4-dwz packages provide the Red Hat
Developer Toolset version of dwz.

This enhancement update adds the devtoolset-4-dwz packages to Red Hat Developer
Toolset 4.0 for Red Hat Enterprise Linux. These packages include dwz 0.12, which
provides the following bug fix over the version included in Red Hat Developer
Toolset 3.1:

• A bug which resulted in the possibility of dwz producing binaries or shared

libraries with unaligned non-allocated ELF sections has been fixed.

(BZ#1243063)

All users who require devtoolset-4-dwz are advised to install these new
packages.
