In my specific case (https://github.com/iree-org/iree-turbine/blob/main/iree/turbine/kernel/wave/codegen.py#L808), I generate gathers directly, without going through linalg. Also as side note, indices are constructed from user-provided sympy exprs, so we don't know beforehand if it's a step or not.
