Hi,

I have the following code in TableGen language:

bits<32> insn;
bits<4> CRm = {0, 0, 1, 1};
let insn{11-8} = CRm;

Is there a way to get the bit numbers (in this case 11-8, to which a list of constant bits (CRm) is assigned) using Record interfaces? When I iterate bits of insn, it doesn’t contain the VarBitInit of CRm, because insn consists of the BinInit objects.

Thanks, Ivan
