        * freeze.adb (Late_Freeze_Subprogram): Following AI05-151,
        a function can return a limited view of a type declared
        elsewhere. In that case the function cannot be frozen at the end
        of its enclosing package. If its first use is in a different unit,
        it cannot be frozen there, but if the call is legal the full view
        of the return type is available and the subprogram can now be
        frozen. However the freeze node cannot be inserted at the point
        of call, but rather must go in the package holding the function,
        so that the backend can process it in the proper context.

        * checks.adb (Generate_Range_Check): For the case of converting
        a base type with a larger range to a smaller target subtype, only

        because the restriction is per-object.
        (Check_Restriction): After possible message, reset the value
        of of a checked max_parameter restriction to zero, to prevent
        cascaded errors.
        * sem_ch3.adb (Build_Derived_Private_Type): Use base of parent
        (sub)type to determine whether derived type should be on the

2014-08-01  Ed Schonberg  <schonberg@adacore.com>

        * sem_res.adb (Resolve_Entry_Call): When an entry has
        preconditions, the entry call is wrapped in a procedure call
        that incorporates the precondition checks. To prevent a double
        expansion, with possible duplication of extra formals, that
        procedure call must only be pre-analyzed and resolved. Expansion
        takes place upon return to the caller Resolve_Call.

        An attribute_reference to Loop_Entry denotes an iterator
        specification: its prefix is an object, as is the case for 'Old.
        b) If the domain of iteration is an expression whose type has
        the Iterable aspect defined, this is an iterator specification.

        to check legality of an initial value for an imported entity.

        * sem_aggr.adb (Resolve_Array_Aggregate): Better placement

        predicates. The new placement avoids posting messages on previous
        subtype declarations rather than on the aggregate itself.
        * sem_disp.adb (Is_Inherited_Public_Operation): New predicate for
        Add_Dispatching_Operation, to handle properly the overriding of
        the predefined operations on controlled types, when the partial

        * a-exextr.adb, a-exstat.adb, exp_intr.ads, s-tassta.adb:
        Exception_Information is used to produce useful debugging
        information for the programmer. However, it was also used to
        implement the stream attributes for type Exception_Occurrence. The
        latter requires a stable and portable interface, which meant
        that we couldn't include a symbolic traceback. A separate set of
        routines was used to provide symbolic tracebacks under program
        control (i.e. not automatically). The goal of this ticket is
        to provide such automatic tracebacks, so the change here is to
        split the two functionalities: Exception_Information gives the
        maximally useful information for debugging (i.e. it now includes
        a symbolic traceback when a decorator is set, and it can be
        improved freely in the future without disturbing streaming).
        Untailored_Exception_Information always uses hexadecimal addresses
        in the traceback, has a stable and portable output, and is now
        used for streaming.

2014-07-30  Eric Botcazou  <ebotcazou@adacore.com>

        * exp_aggr.adb (Expand_Array_Aggregate): Add missing test

        Finalize procedures for this type.
        (Finalize): When finalizing a reference_preserving_key, verify
        that the key of the new value is equivalent to the key of the

        Cleanup: Make the three versions of System.Traceback.Call_Chain
        have the same interface. Use an array for the Traceback parameter
        instead of an Address.  This will enable reduction in code
        duplication.

        is given.

        attaching pragma to entity, to account for declaration not coming
        from source.
        * sem_res.adb (Resolve_Call): Issue warning and flag subprogram

        build-in-place function call to initialize the Timer_Queue.
        * s-traent.adb, s-traent.ads, s-traent-vms.adb, s-traent-vms.ads:
        Turn off polling in these units, because otherwise we get

        switch is used.
        * s-tassta.adb (Create_Task): Make sure independent tasks
        are created with Parent = Environment_Task. This was not true,
        for example, in s-interr.adb, when Interrupt_Manager does "new
        Server_Task"; the Server_Task had Parent = Interrupt_Manager,
        which is wrong because the master is determined by the access
        type, which is at library level.
        * s-tasuti.adb (Make_Independent): Avoid setting Parent; it is
        now set correctly by Create_Task.

        * frontend.adb (Frontend): Revert to previous method of detecting
        temporary configuration pragma files, recognizing such files by
        ".tmp" in the name. This is more general than detecting pragmas
        Source_File_Name_Project, because it allows any tool to use
        this naming convention, no matter the content of the file.

        be performed when analysing the inlined code.

        already a transient scope, and we should not establish a new one.
        * exp_ch7.adb (Insert_Actions_In_Scope_Around): New formal Clean. If
        True, also insert cleanup actions in the tree.

        * sem_res.adb (Resolve_Unchecked_Conversion): Within an inlined
        body the operand of an unchecked conversion may be a literal, in
        which case its type is the target type of the conversion. This
        is in contrast to conversions in other contexts, where the
        operand cannot be a literal and must be resolvable independent
        of the context.

2014-07-30  Pierre-Marie Derodat  <derodat@adacore.com>

        * gcc-interface/decl.c (gnat_to_gnu_entity) <object>: Create a

        subprogram has multiple returns, or not a single last return
        statement, in GNATprove mode.

        inlining first.

2014-07-30  Ed Schonberg  <schonberg@adacore.com>

        * s-tasuti.ads, s-tasuti.adb (Make_Independent): Change this
        from a procedure to a function, so that it can more easily be
        called before the "begin" of a task.
        * s-taasde.ads (Delay_Block): Make this type immutably limited,
        so we can use a build-in-place function call to initialize
        Timer_Queue in the body.
        * a-rttiev.adb, s-asthan-vms-alpha.adb, s-asthan-vms-ia64.adb,
        * s-interr.adb, s-interr-hwint.adb, s-interr-sigaction.adb,
        * s-interr-vms.adb, s-taasde.adb: Each independent task now calls
        Make_Independent before reaching its "begin", to avoid race
        conditions. This causes the activating task to wait until after
        Make_Independent is complete before proceeding.  In addition,
        we initialize data structures used by independent tasks before
        activating those tasks, to avoid possible use of uninitialized data.
        * s-interr.ads, s-intman.ads, s-taspri-posix.ads, s-tasdeb.ads:

        to False when inlining is not possible.
        * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Set Is_Inlined
        flag to indicate that subprogram is fully inlined. To be reversed

2014-07-30  Robert Dewar  <dewar@adacore.com>

        * exp_attr.adb, checks.adb, sem_util.adb, sem_util.ads, sem_attr.adb:
        Change No_Scalar_Parts predicate to Scalar_Part_Present and
        invert sense of test. This avoids the "not No_xxx" situation
        which is always ugly.

2014-07-30  Ed Schonberg  <schonberg@adacore.com>

        * inline.adb (Expand_Inlined_Call): When generating code for
        an internal subprogram the expansion uses the location of the
        call, so that gdb can skip over it. In GNATprove mode we want to
        preserve slocs of original subprogram when expanding an inlined
        call, to obtain better warnings, even though subprogram appears
        not to come from source if it is the inlining of a subprogram
        body without a previous spec.

        generated in an inlined context.

2014-07-30  Doug Rupp  <rupp@adacore.com>

        * sem_attr.adb (Analyze_Array_Component_Update): New routine.
        (Analyze_Attribute): Major cleanup of attribute

        (Check_Component_Reference): Removed.

        (Insert_Child): Add local variable First. Capture the index of the
        first node being created to ensure correct cursor construction
        later on. Use the three parameter version of Allocate_Node
        when creating multiple children as this method allows aspect
        Default_Value to take effect (if applicable).

        the prefix of attribute 'Access.
        * sem_ch6.adb (Analyze_Expression_Function): Remove local

        * sem_ch3.adb (Constrain_Corresponding_Record): For the case
        of the subtype created for a record component, do not mark
        the subtype as frozen. For one thing, this is anomalous (in
        particular, the base type might not itself be frozen yet);
        furthermore, proper freezing of the subtype must happen in any
        case. So, we just mark the subtype as requiring delayed freezing
        (and we'll actually freeze it when generating the init_proc of
        the enclosing record).
        Also change the name of the constrained record subtype (append a
        'C' so that it is clearly different from the unconstrained record
        type, "related_idV") to make debugging easier.
        (Process_Full_View): When creating a full subtype for a pending
        private subtype, re-establish the scope of the private subtype

        indication denotes an access type, and create a null-excluding
        subtype for it.
        * sinfo.ads, sinfo.adb: New attribute Null_Excluding_Subtype,

        rounded up to Storage_Alignment. Storage_Alignment on the
        allocation header is not required by our internals so was
        overkill. 'Object_Size is enough to ensure proper alignment
        of the header address when substracted from a storage address
        aligned on Storage_Alignment.
        (Minimum_Allocation): Rename as Extra_Allocation, conveying that
        this is always added on top of the incoming allocation requests.
        (Align): New function, to perform alignment rounding operations.

        * sem_ch4.adb (Try_Container_Indexing):  If the container
        type is a derived type, the value of the inherited  aspect is

        * sinfo.ads, sinfo.adb: New attribute Generalized_Indexing, for
        indexed_components that are instances of Ada 2012 container
        indexing operations. Analysis and resolution of such nodes

        preserved for ASIS operations. If expansion is enabled, the
        indexed component is replaced by the value of this attribute,

        in a dereference operation.

        Generalized_Indexing attribute when appropriate.

        Generalized_Indexing.

        * s-taskin.ads: Minor comment fix.
        * s-tassta.adb (Abort_Dependents): Don't abort all dependents;
        just direct dependents. If this is actually an abort, each task

        get aborted, as before. However, when this is called the second
        time from Vulnerable_Complete_Master "for convenience" (i.e. to
        kill off tasks waiting at terminate alternatives), aborting
        indirect dependents is wrong, because it causes some unrelated
        tasks to get aborted.

        object is declared, it is rewritten as a renaming of an dynamic

        entity already declared, and then the name is modified to reflect
        the original one. the modification of the name must preserve
        the source location of the original, to prevent spurious errors
        when compiling with style checks if the declaration involves
        more than one entity.

        interpretations that do not come from other predefined units,
        to prevent spurious ambiguities in the presence of user-defined
        operators in the context of (an instance of) a predefined unit.

        * sem_util.adb (Check_Function_Writable_Actuals): 1) Do not
        examine code that does not come from source. The check does not
        apply to code generated for constraint checks, and such code may
        generate spurious error messages when compiled with expansion
        disabled (as in a generic unit) because side effects may not
        have been removed.
        2) Make error messages more explicit: indicate the component
        of the  construct whose value is indeterminate because of a
        call to a function with in-out parameter in another component,
        when there is no mandated order of execution between the two
        components (actuals, aggregate components, alternatives).
