From 2b5355c8ab383d86bb6332dd29c417a6a1bc52bd Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Wed, 6 May 2015 23:29:33 -0400 Subject: [PATCH] st/mesa: make sure to create a "clean" bool when doing i2b MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit i2b has to work for all integers, not just 1. INEG would not necessarily result with all bits set, which is something that other operations can rely on by e.g. using AND (or INEG for b2i).
