        to propagate dimension information from expression to named

        * sem_dim.adb (Analyze_Dimension_Number_Declaration): New
        procedure, to propagate dimension information from expression

        a) If one operand is a literal that is the value of a declared
        constant after constant-foloding, use the dimensions of the
        declared constant.
        b) If an operand is a literal that is a contant-folded expression,
        and expander is active, do not report a dimension mismatch if
        literal does not carry them, because dimension matching will
        have been checked previously.

        the reference may designate an object of the same type declared
        in the enclosing context prior to the body.

        function call from Expression (Func_Call) when Nkind (Func_Call)
        is N_Type_Conversion, since conversions are allowed in "anonymous"

        SS_Release for a block statement enclosing the return statement in the
        case where a build-in-place function return is returning
        the result on the secondary stack. This is accomplished by
        setting the Sec_Stack_Needed_For_Return flag on such blocks.
        It was already being set for the function itself, and it was
        already set correctly for blocks in the non-build-in-place case
        (in Expand_Simple_Function_Return).

        improvements that were already done in the definite case
        (Ada.Containers.Vectors, i.e. a-convec). This includes the

        on "=" composing, but that doesn't quite work -- we want the "="

2015-10-16  Bob Duff  <duff@adacore.com>

        * a-contai.ads: Add two check names: Container_Checks and
        Tampering_Check.  Move the tampering check machinery from
        Ada.Containers.Vectors to Ada.Containers. Later we can share it
        with other containers.
        Disable the tampering machinery in the presence of
        Suppress(Tampering_Check).
        Simplify the implementation of tampering checks. E.g. use RAII
        to make incrementing/decrementing of the counts more concise.
        * a-contai.adb: New package body, implementing the above.
        * a-convec.ads, a-convec.adb: Use tampering check machinery
        in Ada.Containers.
        Disable all checking code when checks are suppressed.
        Simplify many of the operations. Implement "&" in terms of Append,
        rather than "by hand".
        Remove: function "=" (L, R : Elements_Array) return Boolean is
        abstract; so we can call the predefined "=" on Elements_Array.
        For "=" on Vectors: Previously, we returned True immediately if
        Left'Address = Right'Address.  That seems like a non-optimization
        ("if X = X" is unusual), so removed that.  Simplify by using
        slice comparison ("=" on Element_Array will automatically call
        "=" on the components, even if user defined).

2015-10-16  Ed Schonberg  <schonberg@adacore.com>

        If Typ is a generic formal incomplete type, look at the actual

        initial_value_needs_conversion and adjust to above renaming.

        is compound.  Adjust calls to elaborate_reference and build a
        compound expression if needed.
        (struct er_dat): Add N field.
        (elaborate_reference_1): Remove N parameter and adjust.
        (elaborate_reference): Add INIT parameter and pass it in the call to

        regular object declarations when it comes to creating a temporary.

2015-05-28  Ed Schonberg  <schonberg@adacore.com>

        * sem_ch3.adb (Is_Visible_Component): Component is visible
        in a derived type if inherited through an ancestor that has a
        partial view of the original type holding the component, if the
        full view of that original type is in scope.
        * sem_util.ads (Get_Body_From_Stub): Works for all kinds of stubs.

2015-05-28  Bob Duff  <duff@adacore.com>

        * sem_util.adb (Requires_Transient_Scope): For definite untagged
        subtypes, we should never have to use the secondary stack. This moves
        toward that goal. But there are still cases that don't work.
        Here, we move the check for Is_Definite first, but add a
        special-purpose check for Has_Discrim_Dep_Array.

2015-05-28  Bob Duff  <duff@adacore.com>

        * sem_util.adb (Requires_Transient_Scope): Avoid returning
        function results on the secondary stack in so many cases.

        * sem_util.adb (Wrong_Type): In any instance, do not emit error
        if type of expression is the partial view of the expected type.

2015-05-28  Ed Schonberg  <schonberg@adacore.com>

        * sem_res.adb (Resolve_Actuals): a)  The replacement of formal
        names in named associations only needs to be done within an
        instance, on a call to a primitive of a formal derived type,
        where the actual subprogram may have different formal names than
        those of the primitive operation of the formal type.
        b) Defaulted parameters must be taken into account when obtaining
        the names of the formals of the actual subprogram being called.

2015-05-28  Robert Dewar  <dewar@adacore.com>

        * sem_ch13.adb, sem_disp.ads: Minor reformatting.

2015-05-28  Ed Schonberg  <schonberg@adacore.com>

        * sem_util.adb (Set_Debug_Info_Needed): For a private type
        whose full view is itself a derived private type, set flag on
        underlying full view as well, for proper gdb display.

2015-05-28  Bob Duff  <duff@adacore.com>

        * exp_tss.ads: Minor comment fix.
        * exp_ch3.adb (Build_Array_Init_Proc, Build_Record_Init_Proc):
        Inline init_procs when the type has controlled parts. Remove
        obsolete comments about those init_procs -- init_procs for
        such types are no longer complex. A typical init_proc just
        initializes the 'Tag field, and calls the parent init_proc
        (e.g. for Limited_Controlled), which calls the grandparent
        (for Root_Controlled), which does nothing. This all boils down
        to one instruction when inlined.
        * exp_ch7.adb (Create_Finalizer): Inline the finalizer.

2015-05-28  Ed Schonberg  <schonberg@adacore.com>

        * sem_ch4.adb (Analyze_Selected_Component): If the type to use
        is a derived type and is a generic actual, the selected component
        appears within an instance body, and the check over the type
        has failed, examine ancestor types for the desired component.
        (Find_Component_In_Instance): If record type is a derived type,
        examine all ancestors in order to locate desired component.

2015-05-27  H.J. Lu  <hongjiu.lu@intel.com>

        * gcc-interface/Makefile.in (TOOLS_LIBS): Add @NO_PIE_FLAG@.

2015-05-27  Eric Botcazou  <ebotcazou@adacore.com>

        * gcc-interface/trans.c (elaborate_all_entities): Do not elaborate an
        incomplete type coming from a limited_with and whose non-limited view
        comes from the main unit.

        * gcc-interface/decl.c (gnat_to_gnu_entity) <E_Variable>: Move down

        * exp_prag.adb (Expand_Pragma_Abort_Defer): Make
        pragma Abort_Defer do nothing if Abort_Allowed is False.

2015-05-27  Arnaud Charlet  <charlet@adacore.com>

2015-05-27  Doug Rupp  <rupp@adacore.com>

        * adaint.c (__gnat_tmp_name) [vxworks]: Robustify and use for rtp as
        well as kernel.

2015-05-27  Pierre-Marie de Rodat  <derodat@adacore.com>

        * par_sco.adb (Process_Decision): Store sloc to
        condition/pragmas SCOs associations into a temporary table before
        moving them to the SCO_Raw_Hash_Table so that we can back them
        out just like we do for SCO entries that are simple decisions
        in an expression context.

2015-05-27  Ed Schonberg  <schonberg@adacore.com>

        * sem_ch6.adb (Process_Formals): A non-private formal type that
        is a limited view does not have a list of private dependents.

2015-05-27  Ed Schonberg  <schonberg@adacore.com>

        * exp_ch5.adb (Expand_N_Case_Statement): If the expression in
        the case statement is a compile-time known value, we look for a
        corresponding alternative to optimize the case statement into a
        single case. If the type has a static predicate and the expression
        does not satisfy the predicate, there is no legal alternative and
        this optimization is not applicable.  Excecution is erroneous,
        or else if assertions are enabled, an exception will be raised
        earlier, at the point the expression is elaborated.

2015-05-27  Robert Dewar  <dewar@adacore.com>

        * sem_elab.adb (Check_Internal_Call_Continue): Suppress
        warning on Finalize, Adjust, or Initialize if type involved has
        Warnings_Off set.

2015-05-27  Ed Schonberg  <schonberg@adacore.com>

        * sem_aux.adb, sem_aux.ads (First_Discriminant): Return empty when

2015-05-26  Robert Dewar  <dewar@adacore.com>

        * errout.ads, sem_ch4.adb, sem_ch6.adb: Minor reformatting.

2015-05-26  Bob Duff  <duff@adacore.com>

        * sem_elab.adb (Check_A_Call): In the case where we're
        calling something in an instance of a generic package that is
        within this same unit (as the call), make sure we treat it
        as a call to an entity within the same unit. That is, call
        Check_Internal_Call, rather than putting "Elaborate_All(X)"
        on X, which would necessarily result in an elaboration cycle in
        static-elaboration mode.

2015-05-26  Eric Botcazou  <ebotcazou@adacore.com>

        * freeze.ads (Is_Atomic_VFA_Aggregate): Adjust profile.
        * freeze.adb (Is_Atomic_VFA_Aggregate): Change Entity

        * exp_aggr.adb (Expand_Record_Aggregate): Likewise.
        (Process_Atomic_Independent_Shared_Volatile): Remove code
        propagating Atomic or VFA from object to locally-defined type.

        * gcc-interface/trans.c (gnat_to_gnu) <N_Object_Declaration>: Really
        force evaluation of the expression, if any, when the object has its
        elaboration delayed.  Do not create a variable at global level.

2015-05-26  Eric Botcazou  <ebotcazou@adacore.com>

        * gcc-interface/trans.c (Attribute_to_gnu) <Attr_Machine>: Do not apply

        (Install_Body): In the presence of actuals that incomplete types
        from a limited view, the instance body cannot be placed after
        the declaration because full views have not been seen yet. Any
        use of the non-limited views in the instance body requires
        the presence of a regular with_clause in the enclosing unit,
        and will fail if this with_clause is missing.  We place the
        instance body at the beginning of the enclosing body, which is
        the unit being compiled, and ensure that freeze nodes for the
        full views of the incomplete types appear before the instance.

        to Freeze_Entity.  In addition to the previous processing steps
        at the freeze point of an object, this procedure also handles
        aggregates in object declarations, when the declaration carries

        * sem_util.adb (Build_Default_Subtype): If the subtype is created
        for a record discriminant, do not analyze the declarztion at

        do not generate a separate object declaration for the controlling

        dispatching call. Otherwise, the declaration (which involves a
        call to String'Input, returning a dynamically sized value on the
        secondary stack) will be expanded outside of proper secondary
        stack mark/release operations, and will thus cause a secondary

2015-01-06  Ed Schonberg  <schonberg@adacore.com>

        * sem_ch13.adb (Analyze_Aspect_Specifications): For aspects
        that specify stream subprograms, if the prefix is a class-wide

        to the same class-wide type.
        (Default_Iterator): An iterator defined by an aspect of some
        container type T must have a first parameter of type T, T'class,

2015-01-06  Olivier Hainque  <hainque@adacore.com>

        * set_targ.ads (C_Type_For): New function. Return the name of
        a C type supported by the back-end and suitable as a basis to
        construct the standard Ada floating point type identified by
        the T parameter. This is used as a common ground to feed both
        ttypes values and the GNAT tree nodes for the standard floating
        point types.
        * set_targ.adb (Long_Double_Index): The index at which "long
        double" gets registered in the FPT_Mode_Table. This is useful to
        know whether we have a "long double" available at all and get at
        it's characteristics without having to search the FPT_Mode_Table
        when we need to decide which C type should be used as the
        basis for Long_Long_Float in Ada.
        (Register_Float_Type): Fill Long_Double_Index.
        (FPT_Mode_Index_For): New function. Return the index in
        FPT_Mode_Table that designates the entry corresponding to the
        provided C type name.
        (FPT_Mode_Index_For): New function. Return the index in
        FPT_Mode_Table that designates the entry for a back-end type
        suitable as a basis to construct the standard Ada floating point
        type identified by the input T parameter.
        (elaboration code): Register_Back_End_Types unconditionally,
        so C_Type_For can operate regardless of -gnateT. Do it
        early so we can query it for the floating point sizes, via
        FPT_Mode_Index_For. Initialize Float_Size, Double_Size and
        Long_Double_Size from the FPT_Mode_Table, as cstand will do.
        * cstand.adb (Create_Float_Types): Use C_Type_For to determine
        which C type should be used as the basis for the construction
        of the Standard Ada floating point types.
