From 1f1102c8349bd06d579e542ded32fb1aea8a27ab Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Wed, 31 Dec 2014 17:38:05 -0800 Subject: [PATCH] i965: Copy shader->shadow_samplers to prog->ShadowSamplers. ir_to_mesa does this - apparently we just forgot or something. Without this, we'll guess the wrong texture swizzle (XYZW for color instead of XXX1 for depth) when doing precompiles. This cuts 26 shader recompiles in a time demo of "Counter Strike: Global Offensive" (58 -> 32) on Sandybridge. Haswell still has 0 recompiles.
