A distinct attribute associates a referenced attribute with a unique identifier. Every call to its create function allocates a new distinct attribute instance. The address of the attribute instance temporarily serves as its unique identifier. Similar to the names of SSA values, the final unique identifiers are generated during pretty printing. Examples: #distinct = distinct[0]<42.0 : f32> #distinct1 = distinct[1]<42.0 : f32> #distinct2 = distinct[2]<array<i32: 10, 42>> This mechanism is meant to generate attributes with a unique identifier, which can be used to mark groups of operations that share a common properties such as if they are aliasing. The design of the distinct attribute ensures minimal memory footprint per distinct attribute since it only contains a reference to another attribute. All distinct attributes are stored outside of the storage uniquer in a thread local store that is part of the context. It uses one bump pointer allocator per thread to ensure distinct attributes can be created in-parallel.
