From d548d47edf9f05e6dbf9656abc2f8e78d02cb2f6 Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Fri, 9 May 2014 15:56:05 +1000 Subject: [PATCH] nvc0: add maxwell (sm50) compiler backend The big missing part here is proper sched data calculations, but hopefully the chosen placeholder will be sufficient for now. Passes piglit as well as GK107 does.
