Could you paste an example of how rest looks like and what you want category_args to be?

For example, when the function is looking at the following op_def (showing just the start):

def SPIRV_VectorTimesScalarOp : SPIRV_Op<"VectorTimesScalar", [Pure]> {
  • rest is , [Pure]
  • we want category_args to be empty

And in this other op_def (again just the start):

def SPIRV_UDivOp : SPIRV_ArithmeticBinaryOp<"UDiv",
                                        SPIRV_Integer, [UnsignedOp, UsableInSpecConstantOp]> {
  • rest is , SPIRV_Integer, [UsableInSpecConstantOp] (whitespace compressed for clarity)
  • we want category_args to be , SPIRV_Integer.

There are different ways to handle this, e.g. store category args as an array and re-join at its users, but would've been larger changes without clear extra benefit.
