UnknownLoc dataclass

Bases: ParametrizedAttribute, BuiltinAttribute

Syntax:

unknown-location ::= `unknown`

Source location information is an extremely integral part of the MLIR infrastructure. As such, location information is always present in the IR, and must explicitly be set to unknown. Thus, an instance of the unknown location represents an unspecified source location.

Example:

loc(unknown)

An instance of this location represents a tuple of file, line number, and column number. This is similar to the type of location that you get from most source languages.

UnregisteredAttr dataclass

Bases: ParametrizedAttribute, BuiltinAttribute, ABC

An unregistered attribute or type.

Each unregistered attribute is registered as a subclass of UnregisteredAttr, and attribute with different names have distinct subclasses.

Since attributes do not have a generic format, unregistered attributes represent their original parameters as a string, which is exactly the content parsed from the textual representation.
