An elaborable construct is in
the elaborated state after the normal completion of its elaboration.
Prior to that, it is not yet elaborated.
9
For a construct
that attempts to use a body, a check (Elaboration_Check) is performed,
as follows:
10/1
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.
11
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.
12
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.
13
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.
14
The exception Program_Error is
raised if any of these checks fails.
