# Why core aten IR doesn’t contain scalar\_tensor overload version of some ops, like bitwise-like ops, remainder and so on?

Many ops has scalar\_tensor version in native\_functions.yaml, but are not included in core aten IR set. Some of them has same results between scalar\_tensor version and scalar version like bitwise\_and, but some are different like remainder and bitwise\_shift. Is it missing or is there some other reason?
