Hi all, My question is related to the register usage in instruction definition at TARGETInstrInfo.td file. I have defined new Target with it Registers and instructions. Now I need to generate an instruction like: mov MYREG1_NAME, MYREG2_NAME for the built-in function taking one constant integer argument, such as "__builtin_my_function_name(88)" I wondering whether it is possible to do this using only TableGen ? I assume that I should only define a class in TARGETInstrInfo.td file. Currently I have done the following: in...

Also just Updating some status for my questioin: I have continued with using *Defs* list. It allows me to keep Registers as an implicit operands of /*MachineInstr*/ and later during its lowering pass them to the /*MCInstr*/. Now seems I need
