A TableGen backend can define how certain classes can be expanded into ordered sets of defs, typically by evaluating a specific field in the record. The SetTheory class can then evaluate DAG expressions that refer to these named sets. A number of standard set and list operations are predefined, and the backend can add more specialized operators if needed. The -print-sets backend is used by SetTheory.td to provide examples. This is intended to simplify how register classes are defined: def GR32_NOSP : RegisterClass<"X86", [i32], 32, (sub GR32, ESP)>; llvm-svn: 132621 |
