From ab5b7a0fe659ff6f9c1885d5cb047b6531959506 Mon Sep 17 00:00:00 2001 From: Timothy Arceri Date: Sun, 2 Aug 2015 14:57:38 +1000 Subject: [PATCH] nir: Use a single bit for the dual-source blend index MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The only values allowed are 0 and 1, and the value is checked before assigning. This is a copy of 8eeca7a56c that seems to have been made to the glsl ir type after it was copied for use in nir but before nir landed.
