4 Subject: [PATCH 04/20] anv/pipeline: Only consider double elements which
5 actually exist
6
7 The brw_vs_prog_data::double_inputs_read field comes directly from
8 shader_info::double_inputs which may contain inputs which are not
9 actually read. Instead of using it directly, AND it with inputs_read
10 which is only things which are read. Otherwise, we may end up
11 subtracting too many elements when computing elem_count.
