           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal

Hello,

for gcc's vector extension to be really useful, we need a way to access a large
enough subset of operations on vectors in a target-independent way. C exposes
comparisons (< <= > >= == !=) and shifts (<< >>), but C++ doesn't. Either these
operators should be implemented in the C++ front-end as well, or some builtins
should be provided with the same role (__builtin_vec_less?).
