[PATCH] D118999: [OpenCL] Adjust diagnostic for subgroup support.

[Anton Zabaznov via Phabricator via cfe-commits]

azabaznov added a comment.

It seems hard to find a direct mention in the spec, but in the API spec:

//CL_DEVICE_SUB_GROUP_INDEPENDENT_FORWARD_PROGRESS: Is CL_TRUE if this device supports independent forward progress of sub-groups, CL_FALSE otherwise. This query must return CL_TRUE for devices that support the cl_khr_subgroups extension, and must return CL_FALSE for devices that do not support subgroups.//
