From cd4a14be063957964ae54e0e828174b9e40961e0 Mon Sep 17 00:00:00 2001 From: Neil Roberts Date: Tue, 12 Dec 2017 17:22:49 +0100 Subject: [PATCH] spirv: Handle XFB variable decorations These set the new explicit XFB members on nir_variable. This is needed to support ARB_gl_spirv, as Vulkan doesn't support transform feedback.
