From 10dbd029279dda1689410d8ef2bc5aba64dd5958 Mon Sep 17 00:00:00 2001 From: Bryan Cain Date: Fri, 2 Sep 2011 00:10:50 -0500 Subject: [PATCH] glsl_to_tgsi: use UARL instead of I2F and ARL Since TGSI now has a UARL opcode that takes an integer as the source, it is no longer necessary to hack around the lack of an integer ARL opcode using I2F. UARL is only emitted when native integers are enabled; ARL is still used otherwise.
