From 0d1eef536bc744f5c4dcdf854ad6adfdfe4f4dcb Mon Sep 17 00:00:00 2001 From: Jordan Justen Date: Wed, 14 Oct 2015 11:33:03 -0700 Subject: i965/fs: Ignore compute shaders in brw_nir_lower_inputs The commit shown below caused compute shaders to hit the unreachable in the default of the switch block. Since compute shaders don't have any inputs, we can make brw_nir_lower_inputs a no-op for CS. commit 2953c3d76178d7589947e6ea1dbd902b7b02b3d4 Author: Kenneth Graunke Date: Fri Aug 14 15:15:11 2015 -0700 i965/vs: Map scalar VS input locations properly; avoid tons of MOVs.
