-
- procedure Exchange_Declarations (Id : Entity_Id);
- -- Exchange private and full declaration on entry/exit from a package

-
- 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.
