-Custom builders for Attributes to be used during Operation creation can be
-registered by way of the `register_attribute_builder`. In particular the
-following is how a custom builder is registered for `I32Attr`:
-
-```python
-@register_attribute_builder("I32Attr")
-def _i32Attr(x: int, context: Context):
- return IntegerAttr.get(
- IntegerType.get_signless(32, context=context), x)
-```
-
-This allows to invoke op creation of an op with a `I32Attr` with
-
-```python
-foo.Op(30)
-```
-
-The registration is based on the ODS name but registry is via pure python
-method. Only single custom builder is allowed to be registered per ODS attribute
-type (e.g., I32Attr can have only one, which can correspond to multiple of the
-underlying IntegerAttr type).
-
-instead of
-
-```python
-foo.Op(IntegerAttr.get(IndexType.get_signless(32, context=context), 30))
-```
-
