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. 2011-09-06 Arnaud Charlet * gcc-interface/Makefile.in (X86_TARGET_PAIRS): Remove duplicate declaration. 2011-09-05 Hristian Kirtchev * s-finmas.adb (Set_Finalize_Address): Explain the reason for the synchronization.

In its old version, the call did not generate a finalization master. (Expand_Freeze_Record_Type): Add local variable Has_AACC. Add code to recognize anonymous access-to-controlled components. Rewrite the machinery which creates finalization masters to service anonymous access-to-controlled components of a record type. In its current state, only one heterogeneous master is necessary to handle multiple anonymous components. (Freeze_Type): Comment reformatting. * rtsfind.ads: Add RE_Set_Is_Heterogeneous to tables RE_Id and RE_Unit_Table. * s-stposu.adb (Allocate_Any_Controlled): Rewrite the machinery which associates TSS primitive Finalize_Address with either the master itself or with the internal hash table depending on the mode of operation of the master. 2011-08-30 Javier Miranda * exp_ch3.adb (Make_Eq_If): If the etype of the _parent component is an interface type then do not generate code to compare this component. Required since they have no components and their equality operator is abstract. 2011-08-30 Steve Baird * sem_util.ads (Deepest_Type_Access_Level): New function; for the type of a saooaaat (i.e, a stand-alone object of an anonymous access type), returns the (static) accessibility level of the object. Otherwise, the same as Type_Access_Level. (Dynamic_Accessibility_Level): New function; given an expression which could occur as the rhs of an assignment to a saooaaat (i.e., an expression of an access-to-object type), return the new value for the saooaaat's associated Extra_Accessibility object. (Effective_Extra_Accessibility): New function; same as Einfo.Extra_Accessibility except that object renames are looked through. * sem_util.adb (Deepest_Type_Access_Level): New function; see sem_util.ads description. (Dynamic_Accessibility_Level): New function; see sem_util.ads description. (Effective_Extra_Accessibility): New function; see sem_util.ads description. * einfo.ads (Is_Local_Anonymous_Access): Update comments. (Extra_Accessibility): Update comments. (Init_Object_Size_Align): New procedure; same as Init_Size_Align except RM_Size field (which is only for types) is unaffected. * einfo.adb (Extra_Accessibility): Expand domain to allow objects, not just formals. (Set_Extra_Accessibility): Expand domain to allow objects, not just formals. (Init_Size): Add assertion that we are not trashing the Extra_Accessibility attribute of an object. (Init_Size_Align): Add assertion that we are not trashing the Extra_Accessibility attribute of an object. (Init_Object_Size_Align): New procedure; see einfo.ads description. * sem_ch3.adb (Find_Type_Of_Object): Set Is_Local_Anonymous_Access differently for the type of a (non-library-level) saooaaat depending whether Ada_Version < Ada_2012. This is the only point where Ada_Version is queried in this set of changes - everything else (in particular, setting of the Extra_Accessibility attribute in exp_ch3.adb) is driven off of the setting of the Is_Local_Anonymous_Access attribute. The special treatment of library-level saooaaats is an optimization, not required for correctnesss. This is based on the observation that the Ada2012 rules (static and dynamic) for saooaaats turn out to be equivalent to the Ada2005 rules in the case of a library-level saooaaat. * exp_ch3.adb (Expand_N_Object_Declaration): If Is_Local_Anonymous_Access is false for the type of a saooaaat, declare and initialize its accessibility level object and set the Extra_Accessibility attribute of the saooaaat to refer to this object. * checks.adb (Apply_Accessibility_Check): Add Ada 2012 saooaaat support. * exp_ch4.adb (Expand_N_In): Replace some Extra_Accessibility calls with calls to Effective_Extra_Accessibility in order to support renames of saooaaats. (Expand_N_Type_Conversion): Add new local function, Has_Extra_Accessibility, and call it when determining whether an accessibility check is needed. It returns True iff Present (Effective_Extra_Accessibility (Id)) would evaluate to True (without raising an exception). * exp_ch5.adb (Expand_N_Assignment_Statement): When assigning to an Ada2012 saooaaat, update its associated Extra_Accessibility object (if it has one). This includes an accessibility check. * exp_ch6.adb (Add_Call_By_Copy_Code): When parameter copy-back updates a saooaaat, update its Extra_Accessibility object too (if it has one). (Expand_Call): Replace a couple of calls to Type_Access_Level with calls to Dynamic_Access_Level to handle cases where passing a literal (any literal) is incorrect. * sem_attr.adb (Resolve_Attribute): Handle the static accessibility checks associated with "Saooaat := Some_Object'Access;"; this must be rejected if Some_Object is declared in a more nested scope than Saooaat. * sem_ch5.adb (Analyze_Assignment): Force accessibility checking for an assignment to a saooaaat even if Is_Local_Anonymous_Access returns False for its type (indicating a 2012-style saooaaat). * sem_ch8.adb (Analyze_Object_Renaming): Replace a call to Init_Size_Align (which is only appropriate for objects, not types) with a call of Init_Object_Size_Align in order to avoid trashing the Extra_Accessibility attribute of a rename (the two attributes share storage). * sem_res.adb (Valid_Conversion) Replace six calls to Type_Access_Level with calls to Deepest_Type_Access_Level. This is a bit tricky. For an Ada2012 non-library-level saooaaat, the former returns library level while the latter returns the (static) accessibility level of the saooaaat. A type conversion to the anonymous type of a saooaaat can only occur as part of an assignment to the saooaaat, so we know that such a conversion must be in a lhs context, so Deepest yields the result that we need. If such a conversion could occur, say, as the operand of an equality operator, then this might not be right. Also add a test so that static accessibilty checks are performed for converting to a saooaaat's type even if Is_Local_Anonymous_Access yields False for the type. 2011-08-30 Javier Miranda * sem_disp.adb (Check_Dispatching_Operation): Complete condition that controls generation of a warning associated with late declaration of dispatching functions. Required to avoid generating spurious warnings. 2011-08-30 Gary Dismukes * sem_ch6.adb (Check_Return_Subtype_Indication): Issue error if the return object has an anonymous access type and the function's type is a named access type. * sem_ch8.adb (Analyze_Object_Renaming): Suppress error about renaming conversions on implicit conversions, since such conversions can occur for anonymous access cases due to expansion. Issue error for attempt to rename an anonymous expression as an object of a named access type. * sem_res.ads (Valid_Conversion): Add defaulted parameter Report_Errs, to indicate whether this function should report errors on invalid conversions. * sem_res.adb (Resolve): For Ada 2012, in the case where the type of the expression is of an anonymous access type and the expected type is a named general access type, rewrite the expression as a type conversion, unless this is an expression of a membership test. (Valid_Conversion.Error_Msg_N): New procedure that conditions the calling of Error_Msg_N on new formal Report_Errs. (Valid_Conversion.Error_Msg_NE): New procedure that conditions the calling of Error_Msg_NE on new formal Report_Errs. (Valid_Conversion): Move declaration of this function to the package spec, to allow calls from membership test processing. For Ada 2012, enforce legality restrictions on implicit conversions of anonymous access values to general access types, disallowing such conversions in cases where the expression has a dynamic accessibility level (access parameters, stand-alone anonymous access objects, or a component of a dereference of one of the first two cases). * sem_type.adb (Covers): For Ada 2012, allow an anonymous access type in the context of a named general access expected type. * exp_ch4.adb Add with and use of Exp_Ch2. (Expand_N_In): Add processing for membership tests applied to expressions of an anonymous access type. First, Valid_Conversion is called to check whether the test is statically False, and then the conversion is expanded to test that the expression's accessibility level is no deeper than that of the tested type. In the case of anonymous access-to-tagged types, a tagged membership test is applied as well. (Tagged_Membership): Extend to handle access type cases, applying the test to the designated types. * exp_ch6.adb (Expand_Call): When creating an extra actual for an accessibility level, and the actual is a 'Access applied to a current instance, pass the accessibility level of the type of the current instance rather than applying Object_Access_Level to the prefix. Add a ??? comment, since this level isn't quite right either (will eventually need to pass an implicit level parameter to init procs). 2011-08-30 Bob Duff * s-taskin.ads: Minor comment fix. 2011-08-30 Ed Schonberg * sem_res.adb (Check_Parameterless_Call): If the node is a selected component and the selector is a dispatching operation, check if it is a prefixed call before rewriting as a parameterless function call. 2011-08-29 Jakub Jelinek * gcc-interface/Makefile.in (../stamp-gnatlib1-$(RTSDIR)): Copy tsystem.h into $(RTSDIR) instead of rts. 2011-08-29 Robert Dewar * sem_ch10.adb, a-coorse.adb, exp_dist.adb, exp_ch3.adb: Minor reformatting. * gcc-interface/Make-lang.in: Update dependencies. 2011-08-29 Yannick Moy * alfa.ads (Name_Of_Heap_Variable): New constant name. * lib-xref-alfa.adb, lib-xref.adb, lib-xref.ads (Drefs): New global table to hold dereferences.

Therefore, the check for Pkind = N_Assignment_Statement is now unconditional -- it doesn't depend on whether Is_Constrained (Typ). 2011-08-03 Robert Dewar * exp_ch5.adb, sem_prag.adb, exp_ch4.adb: Minor reformatting. 2011-08-03 Ed Schonberg * sem_ch3.adb (Build_Itype_Reference): do not create an itype reference for an itype created within a generic unit. 2011-08-03 Eric Botcazou * gnat_ugn.texi (Switches for gcc): Make it clearer that -fno-inline suppresses all inlining. 2011-08-03 Robert Dewar * sem_ch3.adb, sem_res.adb, exp_ch13.adb, exp_disp.adb, exp_aggr.adb: Minor reformatting. 2011-08-03 Thomas Quinot * exp_ch5.adb (Expand_N_Assignment_Statement): Do not force inlining of tagged assignment when discriminant checks are suppressed. This is useless and extremely costly in terms of static stack usage. 2011-08-03 Bob Duff * sem_prag.adb (Get_Base_Subprogram): Do not follow Alias for instances of generics, because this leads to the wrong entity in the wrong scope, causing (e.g.) pragma Export_Procedure to get an error if the entity is an instance.

This is used in Mark_Non_ALFA_Subprogram (renaming of Mark_Non_ALFA_Subprogram_Body) to decide whether to flag the spec or body of the current subprogram as not in ALFA. 2011-08-02 Fabien Chouteau * impunit.adb: Add Ada.Execution_Time.Interrupts in the Ada2012 package list. * a-extiin.ads: New file. 2011-08-02 Bob Duff * a-direct.adb (Rename): Implement AI05-0231-1.

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 * sem_ch13.adb (Analyze_Attribute_Definition_Clause): Ignore size/alignment related attributes in CodePeer_Mode. 2011-08-02 Gary Dismukes * 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.

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 * 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 user-defined operators so that they are allowed in renaming * sem_ch8.adb (Find_Selected_Component): refine the check for prefixing of operators so that they are allowed in renaming.

Other cases were previously checked in the semantics. * par-ch4.adb (P_Name): move checks that a selector name is not character literal or an operator symbol to Find_Selected_Component in the semantics * par-ch5.adb (Parse_Decls_Begin_End): move check that basic declarations are not placed after later declarations in a separate procedure in Sem_Util (possibly not the best choice?), to be used both during parsing, for Ada 83 mode, and during semantic analysis, for SPARK mode. * par-endh.adb (Check_End): move check that end label is not missing to Process_End_Label in the semantics * par-prag.adb (Process_Restrictions_Or_Restriction_Warnings): remove the special case for SPARK restriction * par.adb: use and with Sem_Util, for use in Parse_Decls_Begin_End * restrict.adb, restrict.ads (Check_Formal_Restriction): add a parameter Force to issue the error message even on internal node (used for generated end label).
