The following is an extraction from the Operand class hierarchy of Target.td. I am trying to define a parameterized version of AsmOperandClass with a passed-in bit size. // from Target.td class AsmOperandClass { string Name; } class Operand { AsmOperandClass ParserMatchClass; } // A parameterized AsmOperandClass class myAsmOperandClass<int n> : AsmOperandClass { string Name =

Hi In my MC6809 backend, in llvm/lib/Target/MC6809/InstPrinter/MC6809InstPrinter.cpp, I have the routine void MC6809InstPrinter::printPCRelImmOperand(const MCInst *MI, unsigned OpNo, raw_ostream &O) { const MCOperand &Op = MI->getOperand(OpNo); ZZ if (Op.isImm()) { int64_t Imm = Op.getImm() + 2; <<<======================== O << "$"; if (Imm

Hi, That's what the DecoderMethod is for. Similarly ParserMatchClass for the asm parser and PrintMethod for the asm printer: def CondCodeOperand : AsmOperandClass { let Name = "CondCode"; } def pred : PredicateOperand<OtherVT, (ops i32imm, i32imm), (ops (i32 14), (i32 zero_reg))> { let PrintMethod = "printPredicateOperand";

Hello James, that was also what I've planned to do but just wasn't sure. Thanks for that.
