From 641eda0c792e10c2792730b1833353564479a557 Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Thu, 10 Sep 2015 03:49:36 -0400 Subject: [PATCH] nv50/ir: r63 is only 0 if we are using less than 63 registers It is advantageous to use r63 instead of r127 since r63 can fit into the shorter encoding. However if we've RA'd over 63 registers, we must use r127 as the replacement instead.
