From 390ff8ac54693262e7d56d8d467dbb6be8c858ae Mon Sep 17 00:00:00 2001 From: Caio Marcelo de Oliveira Filho Date: Fri, 21 Jun 2019 16:55:08 -0700 Subject: [PATCH] glsl/nir: Fix copying vector constant values For n_columns == 1, we have a vector which is handled by the else case. Fixes invalid memory access in upcoming ARB_gl_spirv tests. Failure bisected by Arcady Goldmints-Orlov.
