[LLVMdev] Tablegen: Instructions that take immediates or registers as operands
...e registers or

instruction for each possible combination of registers and immediates
(e.g. For ADD it would require four definitions: ADD_imm_imm,

I have tried a few different ways to make this work in tablegen, but I
have been unsuccessful so far. Here is an example of something I have
tried. It fails to compile with tablegen, but I hope it can help
demonstrate what I am trying to do:
