-- Process eliminate pragma (given by Pragma_Node). The number of
-- arguments has been checked, as well as possible optional identifiers,
-- but no other checks have been made. This subprogram completes the
-- checking, and then if the pragma is well formed, makes appropriate
-- entries in the internal tables used to keep track of Eliminate pragmas.
-- The other five arguments are expressions (rather than pragma argument
-- associations) for the possible pragma arguments. A parameter that
-- is not present is set to Empty.
procedure Check_Eliminated (E : Entity_Id);
-- Checks if entity E is eliminated, and if so sets the Is_Eliminated
-- flag on the given entity.
procedure Check_For_Eliminated_Subprogram (N : Node_Id; S : Entity_Id);
-- Check that the subprogram S (or its ultimate parent in the case of a
-- derived subprogram or renaming) has not been eliminated. An error will
-- be flagged if the subprogram has been eliminated, unless the node N
-- occurs within an eliminated subprogram or within a generic unit. The
-- error will be posted on N.
procedure Eliminate_Error_Msg (N : Node_Id; E : Entity_Id);
-- Called by the front-end on encountering a reference to an eliminated
-- subprogram. N is the node for the reference (such as occurs in a call,
-- a protected call or an attribute), and E is the entity of the
-- subprogram that has been eliminated.
