expand out Discrete_Choices that are names of subtypes with
static predicates. This is now done in the analyzer so that the
-gnatct tree is properly formed for ASIS.
* sem_case.ads (Generic_Choices_Processing): Does not apply
to aggregates any more, so change doc accordingly, and remove
unneeded Get_Choices argument.
* sem_ch3.adb (Analyze_Variant_Part): Remove no
longer used Get_Choices argument in instantiation of

* sem_ch7.adb: Revert previous change.
2013-10-10 Gary Dismukes <dismukes@adacore.com>
* sem_ch13.adb (Analyze_Attribute_Definition_Clause): In the case where
the Storage_Pool aspect is specified by an aspect clause and a
renaming is used to capture the evaluation of the pool name,
insert the renaming in front of the aspect's associated entity
declaration rather than in front of the corresponding attribute
definition (which hasn't been appended to the declaration
list yet).
2013-10-10 Ed Schonberg <schonberg@adacore.com>
* sem_ch6.adb (Is_Interface_Conformant): The controlling type
of the interface operation is obtained from the ultimate alias
of the interface primitive parameter, because that may be in

the type extension and not the desired interface.

2013-10-10 Jose Ruiz <ruiz@adacore.com>
* exp_util.adb (Corresponding_Runtime_Package): Remove the condition
related to No_Dynamic_Attachment which was wrong. Protected types
with interrupt handlers (when not using a restricted profile)
are always treated as protected types with entries, regardless
of the No_Dynamic_Attachment restriction.
* exp_ch9.adb (Expand_N_Protected_Type_Declaration): Simplify the code
using the result of Corresponding_Runtime_Package.
(Install_Private_Data_Declarations): When having
static handlers and a non restricted profile, we use the
type Static_Interrupt_Protection always, so we removed an
extra wrong condition looking at the No_Dynamic_Attachment
restriction. Simplify the code using the result of
Corresponding_Runtime_Package.
(Make_Initialize_Protection): Simplify the code using
the result of Corresponding_Runtime_Package.
(Install_Private_Data_Declaration): The No_Dynamic_Attachment
restriction has nothing to do with static handlers. Remove the extra
erroneous condition that was creating the wrong data type.

check, account for invariants coming from the base type. Prevent
the creation of a junk invariant check when the related object
is of an array type and it is initialized with an aggregate.
* exp_util.adb (Make_Invariant_Call): Typ is now a variable. Use
the base type to create an invariant call when the type of the
