# This custom version of allclose is necessary because the native allclose's
# (in native_functions.yaml) signature conflicts with the current function
# signature requirements of Executorch. Specifically, the native returns a scalar
# (bool), but Executorch requires that operators return either void or a tensor.
# To get around this, the below op expects an out tensor which is expected to be
# a single-element bool. The result of the allclose operation is written to that
# tensor. Otherwise, this operator's semantics are the same as the native version.
# TODO(T126667800) Remove dummy_param once custom namespaces are supported in the
# portable op library.

# The argument dummy_param is used solely to disambiguate this op from the native
# allclose(). Otherwise, code calling this op is identical to the native op:
# out = torch.ops.aten.allclose(a, b). The out variant pass attempts to convert
# this call to the nonexistent native allclose.out and fails.
