From b0d1f9a72ff6e1c7164dc22ff5eb3e817f245d13 Mon Sep 17 00:00:00 2001 From: Jason Ekstrand Date: Thu, 21 May 2020 21:37:33 -0500 Subject: [PATCH] nir: Add a nir_shader_preserve_all_metadata helper There are some passes which really work on the shader level and it's easier if we have a helper which preserves metadata on the whole shader.
