From 2897cb3dba9287011f9c43cd2f214100952370c0 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Marek=20Ol=C5=A1=C3=A1k?= Date: Mon, 17 Oct 2016 00:47:49 +0200 Subject: [PATCH] glsl_to_tgsi: remove code for fixing up TGSI labels MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit I don't know what this was supposed to do, but all TGSI labels were always 0.
