From 3b4929ec6e6456fb093483e2dc9ce008622373d6 Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Fri, 15 Feb 2019 00:00:39 -0800 Subject: [PATCH] st/mesa: Copy VP TGSI tokens if they exist, even for NIR shaders. Even if the driver wants to use NIR shaders, we may need to have TGSI tokens for creating draw module vertex shaders for the feedback/select render modes. So...if the st_vertex_program has any TGSI...copy it to the variant.
