From 35942ee8a8fe9b4c7c746590840fb87b02fcf00e Mon Sep 17 00:00:00 2001 From: =?utf8?q?Marek=20Ol=C5=A1=C3=A1k?= Date: Sun, 31 Jul 2016 00:48:11 +0200 Subject: [PATCH] radeonsi: add a standalone compiler amdgcn_glslc MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This will be used by GLSL lit tests. For developers only. It shouldn't be distributable and it doesn't use the Mesa build system.
