Function multi versioning in libstdc++

Hi all,

Does libstdc++ support FMV on x86_64/i86 architectures?  We're heavily dependent on the STL and it would be nice to
know if templated functions get FMV treatment for performance gain.

If not built into libstdc++, is there a way of specifying the FMV attributes before instantiating a templated class?
