From 7b26741806c521279a1b83f2eae40a277d806626 Mon Sep 17 00:00:00 2001 From: Jason Ekstrand Date: Tue, 4 Sep 2018 13:58:01 -0500 Subject: [PATCH] anv/pipeline: Only consider double elements which actually exist The brw_vs_prog_data::double_inputs_read field comes directly from shader_info::double_inputs which may contain inputs which are not actually read. Instead of using it directly, AND it with inputs_read which is only things which are read. Otherwise, we may end up subtracting too many elements when computing elem_count.
