RHEA-2015:2042 - Product Enhancement Advisory

Topic

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

Description

The elfutils packages contain a number of utility programs and libraries related
to the creation and maintenance of executable code. The devtoolset-4-elfutils
packages provide the Red Hat Developer Toolset version of elfutils.

This enhancement update adds the devtoolset-4-elfutils packages to Red Hat
Developer Toolset 4.0 for Red Hat Enterprise Linux. These packages include
elfutils 0.163. This release provides a number of bug fixes and enhancements
over the version included in Red Hat Developer Toolset 3.1, for example:

• Previously, elfutils libraries and tools could crash on malformed ELF files or

incorrect DWARF data. All known ways to crash the libraries and tools on such
incorrect input data have been fixed.

• The following changes and improvements have been made to the eu-addr2line

tool:

• Input addresses are now always interpreted as hexadecimal numbers, never as

octal or decimal numbers.

• A new option, "-a", "--addresses", to print address before each entry.
• A new option, "-C", "--demangle", to show demangled symbols.
• A new option, "--pretty-print", to print all information on one line.
• This update introduces the following improvements to the libdw library:
• A new header file elfutils/known-dwarf.h.
• The preliminary DWARF5 constants "DW_TAG_atomic_type", "DW_LANG_Fortran03",

and "DW_LANG_Fortran08" have been added to the elfutils/dwarf.h file.

• The dwarf_peel_type() function is now able to handle the "DW_TAG_atomic_type"

constant.

(BZ#1224311)

This update also fixes the following bug:

• Previously, the binutils objcopy tool could create separate debuginfo files

with missing information. As a consequence, the elfutils eu-unstrip utility was
unable to reconstruct the original (unstripped) file. With this update,
eu-unstrip reconstructs the missing information from the unstripped file instead
of the debug files, and the ELF file and the separate debug files created by
binutils objcopy can now be correctly reconstructed into their original form.
(BZ#1246390)

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