From 443d3bf3408984b11f99c1077d167d8331609007 Mon Sep 17 00:00:00 2001 From: Jason Ekstrand Date: Fri, 2 Oct 2015 18:31:17 -0700 Subject: [PATCH] i965/wm: Make compute_barycentric_interp_modes take a nir_shader and a devinfo Now that everything comes in through NIR, we can pick this directly out of the shader source and don't need to reference the gl_fragment_program.
