From 97efdc0d57b3b9b6af4a40715482a15f2b8c7d6e Mon Sep 17 00:00:00 2001 From: Timothy Arceri Date: Tue, 30 Jan 2018 11:56:57 +1100 Subject: st/glsl_to_tgsi: move nir detection earlier MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit We move the nir check before the shader cache call so that we can call a nir based caching function in a following patch. Also with this change we simply check if vertex shaders support NIR rather than looping over the stages as mixing of shader types is not supported anyway.
