Detailed Description
An attribute that associates a referenced attribute with a unique identifier.
Every call to the create function allocates a new distinct attribute instance. The address of the attribute instance serves as a temporary identifier. Similar to the names of SSA values, the final identifiers are generated during pretty printing. This delayed numbering ensures the printed identifiers are deterministic even if multiple distinct attribute instances are created in-parallel.
Examples:
#distinct = distinct[0]<42.0 : f32> #distinct1 = distinct[1]<42.0 : f32> #distinct2 = distinct[2]<array<i32: 10, 42>>
NOTE: The distinct attribute cannot be defined using ODS since it uses a custom distinct attribute uniquer that cannot be set from ODS.
