[LLVMdev] Accessing InstrFormat.td fields

[Villmow, Micah]

When I setup my InstrFormat fields, I added some custom fields specific
for my backend. How do I access these from inside LLVM?

 

For example:

class InstrFormat<dag outs, dag ins, string asmstr, list<dag> pattern> 

        : Instruction {

    let Namespace = "AMD";

    dag OutOperandList = outs;

    dag InOperandList = ins;

    let Pattern = pattern;

    let AsmString = asmstr;

    OpCodeModifier ocmod;

}

 

How do I set/read the ocmod struct from either SelectCode or a separate
phase? Is there an example of this?
