From 80bc0b728c195517fd40027bd3c63f2483811b9f Mon Sep 17 00:00:00 2001 From: Jason Ekstrand Date: Wed, 27 Jun 2018 18:30:09 -0700 Subject: [PATCH] anv: Restrict the number of color regions to those actually written The back-end compiler emits the number of color writes specified by wm_prog_key::nr_color_regions regardless of what nir_store_outputs we have. Once we've gone through and figured out which render targets actually exist and are written by the shader, we should restrict the key to avoid extra RT write messages.
