Description Mark Wielaard 2018-03-05 11:58:11 UTC
Please backport the upstream fix for https://sourceware.org/bugzilla/show_bug.cgi?id=22911 to Fedora 27 binutils.

The slowdown of binutils -d on some binaries is huge (going from seconds to minutes). The upstream patch fixes this.

Hi Mark,

  Done.  Please try binutils-2.29-13.fc27.  I am also updating F28 and rawhide.

Cheers
  Nick

Thanks. I took binutils-2.29-13.fc27 from koji and objdump -d processing went from 2 minute 20 seconds to just 10 seconds (with identical output).

Note that Fedora 27 currently still contains binutils-2.29-6.fc27 since there have not been any updates since f27 was released.

A good point - I have submitted a Bodhi update request.
