This issue doesn't occur on x86_64 Fedora 15 but seems to be unrelated to its
used of -mtune=generic.

--- Comment #3 from Francois-Xavier Coudert <fxcoudert at gcc dot gnu.org> ---
I can't reproduce that on x86_64-apple-darwin14 (Yosemite), neither with trunk,
nor 4.9.2, nor 4.8.0. Can anyone test darwin12 or darwin13 to see if it's
OS-dependent? Or was it fixed throughout?
