From 19e0dd1ad3ad43ddc3aeba1e11852dce3f55d1f1 Mon Sep 17 00:00:00 2001 From: Ian Romanick Date: Wed, 18 Oct 2017 08:59:47 -0700 Subject: [PATCH] i965: Don't request GLSL IR lowering of gl_VertexID Let the lowering in NIR handle it instead. This hurts one shader that occurs twice in shader-db (SynMark GSCloth) on IVB and HSW. No other shaders or platforms were affected. total cycles in shared programs: 253438422 -> 253438426 (0.00%) cycles in affected programs: 412 -> 416 (0.97%) helped: 0 HURT: 2 Signed-off-by: Ian Romanick Reviewed-by: Antia Puentes --- src/mesa/drivers/dri/i965/brw_context.c | 1 - 1 file changed, 1 deletion(-) diff --git a/src/mesa/drivers/dri/i965/brw_context.c b/src/mesa/drivers/dri/i965/brw_context.c index fca5c8e3072..4e37425099d 100644 --- a/src/mesa/drivers/dri/i965/brw_context.c +++ b/src/mesa/drivers/dri/i965/brw_context.c @@ -595,7 +595,6 @@ brw_initialize_context_constants(struct brw_context *brw) ctx->Const.QuadsFollowProvokingVertexConvention = false; ctx->Const.NativeIntegers = true; - ctx->Const.VertexID_is_zero_based = true; /* Regarding the CMP instruction, the Ivybridge PRM says: * -- 2.30.2
