procedure Convert_Aggr_In_Assignment (N : Node_Id);
-- If the right-hand side of an assignment is an aggregate, expand the
-- statement into a series of individual component assignments. This is
-- done if there are non-static values involved in either the bounds or
-- the components, and the aggregate cannot be handled as a whole by the
-- backend.

-- N is an array aggregate that may have a component association with
-- an others clause and a range. If bounds are static and the expressions
-- are compile-time known constants, rewrite N as a purely positional
-- aggregate, to be use to initialize variables and components of the type
-- without generating elaboration code.
