Author: Kenneth Graunke <[email protected]> Date: Tue Jan 24 00:45:53 2017 -0800 i965: Use a UW source type for CS_OPCODE_CS_TERMINATE. SIMD16 compute shaders use a send(16) with mlen 1 for the EOT message, using a source of g127 for the single register. With a UD type, this supposedly could read g128, which doesn't exist, causing the simulator to get cranky. Use a UW type to avoid this.
