---------------------
-- Record Representation
---------------------

-- This test evaluates the code efficiency of elaborating an object
-- declaration of a simple record type that has an associated record
-- representation clause.

-- The test and noise versions for this evaluation are structurally
-- identical and consist of a procedure that encloses and calls the
-- function that declares and initializes a record variable, Local.
-- The function returns the size of the record variable, although
-- this is not used in the evaluation.
