; FileCheck Prefixes:
;   ALL - All targets
;   ACC64 - Same as ACC32 but only for 64-bit targets
;   GPR64 - Same as GPR32 but only for 64-bit targets
;   ACC64-TRAP - Same as TRAP and ACC64 combined
;   GPR64-TRAP - Same as TRAP and GPR64 combined
;   NOCHECK - Division by zero will not be detected
