procedure Analyze_Package_Declaration (N : Node_Id);
procedure Analyze_Package_Specification (N : Node_Id);
procedure Analyze_Private_Type_Declaration (N : Node_Id);
procedure End_Package_Scope (P : Entity_Id);
-- Calls Uninstall_Declarations, and then pops the scope stack.
procedure Exchange_Declarations (Id : Entity_Id);
-- Exchange private and full declaration on entry/exit from a package
-- declaration or body. The semantic links of the respective nodes
-- are preserved in the exchange.
procedure Install_Visible_Declarations (P : Entity_Id);
procedure Install_Private_Declarations (P : Entity_Id);
-- On entrance to a package body, make declarations in package spec
-- immediately visible.
-- When compiling the body of a package, both routines are called in
-- succession. When compiling the body of a child package, the call
-- to Install_Private_Declaration is immediate for private children,
-- but is deffered until the compilation of the private part of the
-- child for public child packages.
procedure Install_Package_Entity (Id : Entity_Id);
-- Basic procedure for the previous two. Places one entity on its
-- visibility chain, and recurses on the visible part if the entity
-- is an inner package.
function Unit_Requires_Body (P : Entity_Id) return Boolean;
-- Check if a unit requires a body. A specification requires a body
-- if it contains declarations that require completion in a body.
procedure May_Need_Implicit_Body (E : Entity_Id);
-- If a package declaration contains tasks and does not require a
-- body, create an implicit body at the end of the current declarative
-- part to activate those tasks.
function Is_Fully_Visible (Type_Id : Entity_Id) return Boolean;
-- Indicates whether the Full Declaration of a private type is visible.
procedure New_Private_Type (N : Node_Id; Id : Entity_Id; Def : Node_Id);
-- Common processing for private type declarations and for formal
-- private type declarations. For private types, N and Def are the type
-- declaration node; for formal private types, Def is the formal type
-- definition.
procedure Uninstall_Declarations (P : Entity_Id);
-- At the end of a package declaration or body, declarations in the
-- visible part are no longer immediately visible, and declarations in
-- the private part are not visible at all. For inner packages, place
-- visible entities at the end of their homonym chains. For compilation
-- units, make all entities invisible. In both cases, exchange private
-- and visible declarations to restore order of elaboration.
