            Bug ID: 99510
           Summary: cl_khr_fp64 is reported as supported, but is not, on
                    CAYMAN
           Product: Mesa
           Version: 13.0
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/r600
          Assignee: dri-devel at lists.freedesktop.org
          Reporter: benjiwiebe14 at gmail.com
        QA Contact: dri-devel at lists.freedesktop.org

On CAYMAN, cl_khr_fp64 is listed as a supported extension in clinfo, and
therefore also makes some kernels fail to compile due to their trying to
compile in things that need cl_khr_fp64 support. This causes clpeak to fail
with 'unsupported call to function __floatunsidf in compute_dp_v1'.

If you need more information I will be happy to provide more.
