*objdump* mixed listing speed up
Previously, the BFD library for parsing DWARF debug information and locating source code was very slow. The BFD library is used by the *objdump* tool. As a consequence, *objdump* became significantly slower when producing a mixed listing of source code and disassembly. Performance of the BFD library has been improved. As a result, producing a mixed listing with *objdump* is faster.

FYI - this problem has been addressed by a patch submitted to the FSF binutils: https://www.sourceware.org/ml/binutils/2016-11/msg00050.html Once 7.4 is open for patching I will see about applying it there. Patch added. Verified using reproducer in the original report, with /usr/bin/ceph-osd binary. The difference in the time spent running between binutils-2.25.1-22.base.el7 and binutils-2.25.1-30.base.el7 is quite significant, -30.base.el7 finishes in cca 500 seconds. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA. For information on the advisory, and where to find the updated files, follow the link below. If the solution does not work for you, open a new bug report. https://access.redhat.com/errata/RHBA-2017:1864 |
