[Mesa-dev] [PATCH mesa v2 2/3] nouveau: codegen: Do not silently fail in handeLOAD / handleSTORE / handleATOM

[Hans de Goede]

handeLOAD / handleSTORE / handleATOM can only handle TGSI_FILE_BUFFER
and TGSI_FILE_MEMORY. Make things fail explictly when another
register-file is used in these functions.
