Hmmm the tests are gated by vect_int which sparc declares to support but the
code didn't vectorize, so probably an unsupported operation somewhere..

Could you attach the output of -fdump-tree-vect-all?

Thanks

Hmmm looks like it doesn't support vector comparisons

 missed:   not vectorized: relevant stmt not supported: _6 = _5 <= 255;

I'll probably just have to skip them on sparc*-* then.

    vect: disable bitmask tests on sparc

    These testcases declare requiring vect_int which sparc declares as well
however
    sparc doesn't have an optab to vectorize comparisons so these testcases
fail to
    vectorize and so the tests fail.

    As such best coure of action is to just skip them on sparc as comparisons
are
    somewhat expected from a target that can do SIMD.

fixed by skipping tests since they don't vectorize.
