-- that N can be rewritten as a mere occurrence of Temp.
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.
procedure Convert_Aggr_In_Object_Decl (N : Node_Id);
-- N is an N_Object_Declaration whose expression must be an N_Aggregate or
-- N_Extension_Aggregate with Expansion_Delayed.
-- This procedure performs an in-place aggregate assignment.
function Is_Delayed_Aggregate (N : Node_Id) return Boolean;
-- Returns True if N is an aggregate of some kind whose Expansion_Delayed
-- flag is set (see sinfo for meaning of flag).
function Is_Delayed_Conditional_Expression (N : Node_Id) return Boolean;
-- Returns True if N is a conditional expression whose Expansion_Delayed
-- flag is set (see sinfo for meaning of flag).
function Static_Array_Aggregate (N : Node_Id) return Boolean;
-- 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 used to initialize variables and components of the type
-- without generating elaboration code.
