From 1353ba53977e9a531fcadf3c04ad4c69c32c22c0 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=UTF-8 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).
