From c30587643e34a1f7586adf961e4340bbce90b969 Mon Sep 17 00:00:00 2001 From: Jason Ekstrand Date: Sun, 19 Mar 2017 21:20:28 -0700 Subject: [PATCH] i965/clip: Make brw_clip_prog_key::interp_mode an array Having it be a pointer means that we end up caching clip programs based on a pointer to wm_prog_data rather than the actual interpolation modes. We've been caching one clip program per FS ever since 91d61fbf7cb61a44a where Timothy rewrote brw_setup_vue_interpolation().
