Yes, it's a constant register. Because the instruction cannot contain an immediate value, a constant value may be stored in a constant register, and it's defined _before_ the program starts by

...constraints, then you should partition the registers so that each the register classes line up with the instruction operand requirements. > def ADDgg : BinaryInst<0x51, ( > ops GeneralPurposeRC :$dest, > ope GeneralPurposeRC :$src), "add $dest, $src">; > > def ADDgi : BinaryInst<0x52, ( > ops GeneralPurposeRC :$dest, > ope InputRC :$src), "add $dest, $src">; > > def ADDgc : BinaryInst<0x52, ( > ops GeneralPurposeRC :$dest, > ope ConstantRC :$src), "add $dest, $src">; > > The problem is: SDOperand...
