The elaboration of a declarative_part
consists of the elaboration of the declarative_item
if any, in the order in which they are given in the declarative_part
An elaborable construct is
in the elaborated
state after the normal completion of its elaboration.
Prior to that, it is not yet elaborated
construct that attempts to use a body, a check (Elaboration_Check) is
performed, as follows:
- For a call to a (non-protected) subprogram
that has an explicit body, a check is made that the body is already elaborated.
This check and the evaluations of any actual parameters of the call are
done in an arbitrary order.
- For a call to a protected operation
of a protected type (that has a body -- no check is performed if a pragma
Import applies to the protected type), a check is made that the protected_body
is already elaborated. This check and the evaluations of any actual parameters
of the call are done in an arbitrary order.
- For the activation of a task, a check
is made by the activator that the task_body
is already elaborated. If two or more tasks are being activated together
(see 9.2), as the result of the elaboration
of a declarative_part or the initialization
for the object created by an allocator, this check is done for all of
them before activating any of them.
- For the instantiation of a generic
unit that has a body, a check is made that this body is already elaborated.
This check and the evaluation of any explicit_generic_actual_parameters
of the instantiation are done in an arbitrary order.
The exception Program_Error
is raised if any of these checks fails.
