constraints defined in the DAG node definitions in the .td files. This allows us to infer (and check!) the types for all nodes in the current ppc .td file. For example, instead of: Inst pattern EQV: (set GPRC:i32:$rT, (xor (xor GPRC:i32:$rA, GPRC:i32:$rB), (imm)<<Predicate_immAllOnes>>)) we now fully infer: Inst pattern EQV: (set:void GPRC:i32:$rT, (xor:i32 (xor:i32 GPRC:i32:$rA, GPRC:i32:$rB), (imm:i32)<<Predicate_immAllOnes>>)) from: (set GPRC:$rT, (not (xor GPRC:$rA, GPRC:$rB))) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23284 91177308-0d34-0410-b5e6-96231b3b80d8
