From 19b08e1bb3a3508049d0527743b2f50f855a24c2 Mon Sep 17 00:00:00 2001 From: Jordan Justen Date: Fri, 29 Aug 2014 12:50:46 -0700 Subject: [PATCH] i965/fs: Remove direct fs_visitor brw_wm_prog_key dependence Instead we store a void pointer to the key, and cast it to brw_wm_prog_key for fragment shader specific code paths.
