...ags in the R600 backend with immediate operands, but I can't figure out how to modify the instruction patterns to make this work. For example, I have the class: class R600_1OP <bits<32> inst, string opName, list<dag> pattern, InstrItinClass itin = AnyALU> : InstR600 <inst, (outs R600_Reg32:$dst), (ins R600_Reg32:$src, R600_Pred:$p, i32imm:$flags), !strconcat(opName, " $dst, $src ($p)"), pattern, itin >; And an instruction def: def CEIL : R600_1OP < 0x12, "CEIL", [(set R600_R...

All, The code generator operand class, MachineOperand, has an 8-bit TargetFlags field that the individual targets can use as they please. X86 and ARM use it to encode linker magic on symbol operands. It has been mentioned a couple of times on this list that it is not safe to use TargetFlags on register operands. This is because many target-independent passes are manipulating register operands
