From f979d3cfec2b336801fe59ccd264111f403428f5 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Thu, 5 Nov 2015 14:32:38 +0100 Subject: [PATCH] nv50/ir: Add support for 64bit immediates to checkSwapSrc01 Now that we support 64 bit immediates in insnCanLoad, we need to swap 64 bit immediate sources too for optimal effect.
