From 56434450f634d54dd0e4bf3d243dbf931932ff93 Mon Sep 17 00:00:00 2001 From: Boris Brezillon Date: Wed, 19 Jun 2019 15:05:34 +0200 Subject: [PATCH] nir/lower_tex: Add an assert() in nir_lower_txs_lod() We don't expect the output of a TXS instruction to be wider than a vec3. Add an assert() to make sure this never happens.
