Author: Vadim Girlin <[email protected]> Date: Wed Jul 17 12:00:43 2013 +0400 r600g/sb: fix handling of PS in source bytecode on cayman Actually PS doesn't make sense for cayman and isn't even mentioned in cayman docs, but llvm backend currently uses it in bytecode and, assuming that hw seems to be mostly ok with it, this will allow sb to parse such source bytecode correctly.
