Author: Kenneth Graunke <[email protected]> Date: Sun Sep 24 12:42:52 2017 -0700 i965: Support copy propagating of untyped atomic surface indexes. In the vec4 backend, SHADER_OPCODE_UNTYPED_ATOMIC's src[1] is the surface index. We want to copy propagate so we can use an immediate message descriptor, rather than an indirect send.
