--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Intel(R) Xeon(R) CPU E5620 @2.40GHz
is not IvyBridge, plus even IvyBridge doesn't support lzcnt insn, only Haswell
or some recent AMD CPUs. So, this looks like user error, you shouldn't compile
code you intend to run on non-lzcnt CPUs with -mlzcnt.
