* einfo.ads (Extra_Accessibility_Of_Result): New function; in the
(Ada2012) cases described in AI05-0234 where the accessibility
level of a function result is "determined by the point of
call", an implicit parameter representing that accessibility
level is passed in. Extra_Accessibilty_Of_Result yields this
additional formal parameter. Extra_Accessibility_Of_Result
is analogous to the existing Extra_Accessibility
function used in the implementation of access parameters.
(Set_Extra_Accessibility_Of_Result): New procedure; sets
Extra_Accessibility_Of_Result attribute.
* einfo.adb (Extra_Accessibility_Of_Result): New function.
(Set_Extra_Accessibility_Of_Result): New procedure.
(Write_Field19_Name): Display Extra_Accessibilty_Of_Result attribute.
* sem_util.adb (Dynamic_Accessibility_Level): Set Etype of
an accessibility level literal to Natural; introduce a nested
function, Make_Level_Literal, to do this.
* exp_ch6.ads (Needs_Result_Accessibility_Level): New function;
determines whether a given function (or access-to-function
type) needs to have an implicitly-declared accessibility-level
parameter added to its profile.
(Add_Extra_Actual_To_Call): Export an existing procedure which was
previously declared in the body of Exp_Ch6.
* exp_ch6.adb (Add_Extra_Actual_To_Call): Export declaration by moving
it to exp_ch6.ads.
(Has_Unconstrained_Access_Discriminants): New Function; a
predicate on subtype entities which returns True if the given
subtype is unconstrained and has one or more access discriminants.
(Expand_Call): When expanding a call to a function which takes an
Extra_Accessibility_Of_Result parameter, pass in the appropriate
actual parameter value. In the case of a function call which is
used to initialize an allocator, this may not be possible because
the Etype of the allocator may not have been set yet. In this
case, we defer passing in the parameter and handle it later in
Expand_Allocator_Expression.
(Expand_Simple_Function_Return): When returning from a function which
returns an unconstrained subtype having at least one access
discriminant, generate the accessibility check needed to ensure that
the function result will not outlive any objects designated by its
discriminants.
(Needs_Result_Accessibility_Level): New function; see exp_ch6.ads
description.
* exp_ch4.adb (Expand_Allocator_Expression): When a function call
is used to initialize an allocator, we may need to pass in "the
accessibility level determined by the point of call" (AI05-0234)
to the function. Expand_Call, where such actual parameters are
usually generated, is too early in this case because the Etype of
the allocator (which is used in determining the level to be passed
in) may not have been set yet when Expand_Call executes. Instead,
we generate code to pass in the appropriate actual parameter
in Expand_Allocator_Expression.
* sem_ch6.adb (Create_Extra_Formals): Create
the new Extra_Accessibility_Of_Result formal if
Needs_Result_Accessibility_Level returns True. This includes the
introduction of a nested procedure, Check_Against_Result_Level.
