"""
The function decorator of Register Pass. Decorator @RegisterPass handles
the function and register it into a core.Pass instance. Use name of function
as Pass type.
Args:
function (callable): The function with return of callable pair(s) that
represents the pattern subgraph and the replace subgraph.
input_specs (dict[str, InputSpec]): Dict of InputSpec to specific the shape/dtype
information of Tensor. Some operators limit the shape and dtype of datas when
create subgraph with Paddle APIs. So user need specify InputSpec of data to
ensure create a correctly subgraph. Of course, this argument is not limited to
matching subgraph. The default is dict().
Returns:
callables: Callable pair(s).
Examples:
.. code-block:: python

def RegisterPass(function=None, input_specs=dict()):
"""
The function decorator of Register Pass. Decorator @RegisterPass handles
the function and register it into a core.Pass instance. Use name of function
as Pass type.
Args:
function (callable): The function with return of callable pair(s) that
represents the pattern subgraph and the replace subgraph.
input_specs (dict[str, InputSpec]): Dict of InputSpec to specific the shape/dtype
information of Tensor. Some operators limit the shape and dtype of datas when
create subgraph with Paddle APIs. So user need specify InputSpec of data to
ensure create a correctly subgraph. Of course, this argument is not limited to
matching subgraph. The default is dict().
Returns:
callables: Callable pair(s).
Examples:
.. code-block:: python
import paddle
from paddle.fluid.ir import RegisterPass
@RegisterPass
def multi_add_to_addn():
def pattern(x, y, z):
return paddle.add(paddle.add(x, y), z)
def replace(x, y, z):
return paddle.add_n([x, y, z])
return pattern, replace
