From b95fae034fad9471f179761790bd1f01f8bade5c Mon Sep 17 00:00:00 2001 From: Jason Ekstrand Date: Fri, 19 Dec 2014 14:55:45 -0800 Subject: [PATCH] nir/variable: Remove the constant_value field This was a left-over relic of GLSL IR that we aren't using for anything. If we ever want that value again, we can add it back, but NIR constant folding should be just as good as GLSL IR's if not better pretty soon, so I'm not worried about it.
