Author: Ilia Mirkin <[email protected]> Date: Thu Feb 4 22:58:48 2016 -0500 nvc0/ir: fix converting between predicate and gpr The spill logic will insert convert ops when moving between files. It seems like the emission logic wasn't quite ready for these converts. Tested on fermi, and visually looked at nvdisasm output for maxwell.
