--- Comment #22 from Jeffrey A. Law <law at gcc dot gnu.org> ---
Closing.  The original issue was resolved long ago.  It also appears that we're
optimizing appropriately for the -0.0 case when -fno-signed-zeros is enabled.

The VRULL patch Philip references is acked and is expected to further improve
the -0.0 case when we're honoring signed zeros, but that's a separate and
distinct improvement and not directly covered by this BZ.
