        * sem_util.adb, sem_util.ads (Current_Subprogram_Body_Is_Not_In_ALFA):
        if Current_Subprogram is not Empty, set its flag Body_Is_In_ALFA to

2011-08-02  Ed Schonberg  <schonberg@adacore.com>

        * sem_ch6 (Analyze_Expression_Function): treat the function as
        Inline_Always, and introduce a subprogram declaration for it when it is
        not a completion.

        a function body comes from an expression function.

2011-08-02  Gary Dismukes  <dismukes@adacore.com>

        null exclusions to test Can_Never_Be_Null on the anonymous access types
        of the formals rather than testing the formals themselves. Exclude this
        check in cases where the Old_Formal is marked as a controlling formal,
        to avoid issuing spurious errors for bodies completing dispatching
        operations (due to the flag not getting set on controlling access
        formals in body specs).
        (Find_Corresponding_Spec): When checking full and subtype conformance of
        subprogram bodies in instances, pass Designated and E in that order, for
        consistency with the expected order of the formals (New_Id followed by
        Old_Id).

        * exp_atag.ads, exp_atag.adb
        (Build_Common_Dispatching_Select_Statements): Remove argument Loc
        since its value is implicitly passed in argument Typ.
        * exp_disp.adb (Make_Disp_Conditional_Select_Body,

        private type with a tagged full view is not derived in the immediate
        scope of the partial view, (RM 7.3 (7)) use the scope of the base type.

2011-08-02  Robert Dewar  <dewar@adacore.com>

        * exp_ch4.adb: Minor reformatting.

2011-08-02  Ed Schonberg  <schonberg@adacore.com>

        * sem_ch5.adb (Analyze_Loop_Statement):  If the iteration scheme is an
        Ada2012 iterator, the loop will be rewritten during expansion into a
        while loop with a cursor and an element declaration. Do not analyze the
        body in this case, because if the container is for indefinite types the
        actual subtype of the elements will only be determined when the cursor
        declaration is analyzed.

2011-08-02  Arnaud Charlet  <charlet@adacore.com>

        * sem_ch13.adb (Analyze_Attribute_Definition_Clause): Ignore
        size/alignment related attributes in CodePeer_Mode.

2011-08-02  Gary Dismukes  <dismukes@adacore.com>

        * sem_ch3.adb (Check_Ops_From_Incomplete_Type): Remove call to
        Prepend_Element, since this can result in the operation getting the
        wrong slot in the full type's dispatch table if the full type has
        inherited operations. The incomplete type's operation will get added
        to the proper position in the full type's primitives
        list later in Sem_Disp.Check_Operation_From_Incomplete_Type.
        (Process_Incomplete_Dependents): Add Is_Primitive test when checking for
        dispatching operations, since there are cases where nonprimitive
        subprograms can get added to the list of incomplete dependents (such
        as subprograms in nested packages).
        * sem_ch6.adb (Process_Formals): First, remove test for being in a
        private part when determining whether to add a primitive with a
        parameter of a tagged incomplete type to the Private_Dependents list.
        Such primitives can also occur in the visible part, and should not have
        been excluded from being private dependents.
        * sem_ch7.adb (Uninstall_Declarations): When checking the rule of
        RM05-3.10.1(9.3/2), test that a subprogram in the Private_Dependents
        list of a Taft-amendment incomplete type is a primitive before issuing
        an error that the full type must appear in the same unit. There are
        cases where nonprimitives can be in the list (such as subprograms in
        nested packages).
        * sem_disp.adb (Derives_From): Use correct condition for checking that
        a formal's type is derived from the type of the corresponding formal in
        the parent subprogram (the condition was completely wrong). Add
        checking that was missing for controlling result types being derived
        from the result type of the parent operation.

2011-08-02  Yannick Moy  <moy@adacore.com>

        * errout.adb (First_Node): minor renaming

        first node.

2011-08-02  Yannick Moy  <moy@adacore.com>

        * sem_res.adb (Resolve_Logical_Op): ensure N is a binary operator
        before accessing operands.
        * sem_util.adb (Is_SPARK_Initialization_Expr): follow original nodes to
        decide whether an initialization expression respects SPARK rules, as
        the plain node is the expanded one. This allows for more valid warnings
        to be issued.
        * gnat_rm.texi: Minor update.

2011-08-02  Arnaud Charlet  <charlet@adacore.com>

        * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Revert
        previous change.

2011-08-02  Robert Dewar  <dewar@adacore.com>

        * sem_ch3.adb, sem_ch4.adb: Minor reformatting.

2011-08-02  Hristian Kirtchev  <kirtchev@adacore.com>

        * exp_ch5.adb (Expand_Iterator_Loop): Reformatting. Wrap the original
        loop statements and the element renaming declaration with a block when
        the element type is controlled.

2011-08-02  Yannick Moy  <moy@adacore.com>

        * sinfo.ads: Minor formatting.

2011-08-02  Ed Schonberg  <schonberg@adacore.com>

        * sem_aggr.adb (Add_Association): if the association has a box and no
        expression, use the Sloc of the aggregate itself for the new
        association.
        * errout.adb (First_Node): Exclude nodes with no Sloc, and always use
        the Original_Node.

2011-08-02  Hristian Kirtchev  <kirtchev@adacore.com>

        * exp_ch5.adb (Expand_Iterator_Loop): Code cleanup and refactoring.
        When a container is provided via a function call, generate a renaming
        of the function result. This avoids the creation of a transient scope
        and the premature finalization of the container.
        * exp_ch7.adb (Is_Container_Cursor): Removed.
        (Wrap_Transient_Declaration): Remove the supression of the finalization
        of the list controller when the declaration denotes a container cursor,
        it is not needed.

2011-08-02  Yannick Moy  <moy@adacore.com>

        * restrict.adb (Check_Formal_Restriction): only issue a warning if the
        node is from source, instead of the original node being from source.
        * sem_aggr.adb
        (Resolve_Array_Aggregate): refine the check for a static expression, to
        recognize also static ranges
        * sem_ch3.adb, sem_ch3.ads (Analyze_Component_Declaration,
        Array_Type_Declaration): postpone the test for the type being a subtype
        mark after the type has been resolved, so that component-selection and
        expanded-name are discriminated.
        (Make_Index, Process_Range_Expr_In_Decl): add a parameter In_Iter_Schm
        to distinguish the case of an iteration scheme, so that an error is
        issed on a non-static range in SPARK except in an iteration scheme.
        * sem_ch5.adb (Analyze_Iteration_Scheme): call Make_Index with
        In_Iter_Schm = True.
        * sem_ch6.adb (Analyze_Subprogram_Specification): refine the check for

        * sem_util.adb, sem_util.ads (Check_Later_Vs_Basic_Declarations): new
        procedure called from parsing and semantics to check that basic
