    Phoronix: GCC 4.6 Release Candidate Comes w/o P1 Regressions

    It's good to see that the P1's were resolved rather than downgraded to P2's

    It should make for a better release

    I'm just hoping LTO will finally be usable across the whole system now

        "GCC 4.6 delivers Intel Sandy Bridge AVX support and other Core i7 / Core i5 / Sandy Bridge optimizations"
