+ of errors in the documentation in this regard).
+
+ * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
+
+ * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
+ of these procedures are passed a function call that already has
+ build-in-place actuals (testing new flag
+ Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
+ the case where processing continues.
+ (Expand_Call): If the call is generated from a thunk body then we
+ propagate the extra actuals associated with the accessibility
+ level of the access type actuals.
+
+ * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
+ of each extra formal of a protected operation to reference the
+ corresponding extra formal of the subprogram denoted by the
+ operation's Protected_Body_Subprogram.
+
+ * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on

+
+ * sem_util.adb (Is_Preelaborable_Expression): New function to determine

+ requires preelaborable init.
+ (Check_Components): Replace inline code that does partial checking for
+ preelaborable default expressions with call to
+ Is_Preelaborable_Expression.
+ (Has_Preelaborable_Initialization): In the case of a generic actual

+
+ * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a

+ (Is_Leap): Move the routine to the scope of Week_In_Year.
+ (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
+ weekday on which January 1 falls of Year - 1 and Year + 1. This function
+ avoids calling Time_Of and Split, thus making it more efficent.
+ (Week_In_Year): Reimplemented in oder to follow ISO 8601.
+
+ * g-calend.ads (Week_In_Year): Change comment to reflect new

+
+2007-09-26 Emmanuel Briot <briot@adacore.com>
+
+ * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
+ Command_Line): New types
+ (Define_Alias, Define_Prefix, Free): New subprograms. These provide
+ support for defining how switches can be grouped on a command line (as
+ is the case for -gnatw... for GNAT), and how simple switches can be
+ used as aliases for more complex switches (-gnatwa is same as
+ -gnatwbcef...)
+ (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
+ (Start, Current_*): New subprograms
+ Added support for parsing an array of strings in addition to the real
+ command line.
+ (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
+ be moved from the body to the private part of the spec.
+ (*): All subprograms now have an extra parameter with default value to
+ specify which parser should be used. For backward compatibility, it
+ defaults to parsing the command line of the application. They were also
+ modified to properly handle cases where each of the argument does not
+ start at index 1 (which is always true for Ada.Command_Line, but not
+ when processing any Argument_List).
+ (Free): New subprogram
+ (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
+ Argument): New subprograms
+ (Switch_Parameter_Type): New enum, which clarifies the code. The extra
+ special characters like ':', '=',... are now handled in a single place,
+ which makes the code more extensible eventually.
+ (Getopt, Full_Switch): When the switch was returned as part of the
+ special character '*', make sure it is prepended by the switch character
+ ('-' in general), so that the application knows whether "foo" or "-foo"
+ was specified on the command line.
+
+2007-09-26 Florian Villoing <villoing@adacore.com>
+
+ * g-dirope.adb (Remove_Dir): In case we are removing directories
+ recursively, make sure that if an exception is raised during the
+ processing, the current working directory is reset to its initial
+ value before propagating the exception.

+ (Side_Effect_Free): A selected component of an access type that

+ (Check_Conventions): Capture condition to ignore a primitive operation
+ (which is shared between the loop in Check_Conventions and the one in

+ (Analyze_Subprogram_Body): If the return type of a function is an
+ anonymous access to the limited view of a class-wide type, and the

+ function so that code can be generated.
+ (Process_Formals): In case of access-subtype itype whose designated
+ type is also an itype (situation that happens now with access to
+ subprograms) we mark the access-type itype with the Has_Delayed_Freeze
+ attribute to avoid backend problems.
+ (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
+ init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
+ anonymous types' designated types are same before testing
+ Subtypes_Statically_Match.
+ (Create_Extra_Formals): Test for a named access parameter that is a
+ controlling formal as an additional condition for adding an
+ accessibility level formal. This can occur in the subp type created for
+ dispatching calls in Expand_Dispatching_Call, and allows calling
+ Create_Extra_Formals from that procedure rather than special-casing the
+ extra formals there.
+ (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
+ when the function has a controlling result.
+ (Check_Returns): Add much more knowledge of the optimization of local

+ (Expand_Record_Aggregate): Force conversion of aggregates of tagged

+ (Replace_Type): move to Build_Record_Aggr_Code.
+ (Expand_Record_Aggr_Code): if the target of the aggregate is an

+ (Gen_Assign): Do not generate a call to deep adjust routine if the

+ (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in

+ (Expand_N_Attribute_Reference, case Size): Return specified size if

+ (Expand_Allocator_Expression): Call Adjust for initialized allocators of

+ (Apply_Accessibility_Check): Handle allocated objects initialized in

+ (Expand_N_Extended_Return_Statement): Test for a tagged result type

+
+ * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
+ accessibility actual, check for the case of an aliased object that has
+ been rewritten as an Access attribute, and assign Prev to Prev_Orig so
+ we fall into processing for the attribute rather than the name of the
+ object.
+ (Expand_Inline_Call): If an actual is a literal, and the corresponding
+ formal has its address taken in the body, create a temporary to capture
+ value. If the return type is a limited interface, do not treat the
+ return value as Controlled.
+ (Is_In_Place_Function): If the return type is a limited interface,
+ treat as returning in place. The actual returned object may not always
+ be limited, but the caller has to assume that it is returned in place.
+ (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
+ context of an allocator, use the correct finalization chain (that is,
+ the chain belonging to the access type, rather than the chain belonging
+ to the current scope).
+ (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
+ result type rather than a controlling result as a precondition for
+ adding an allocation form actual to a build-in-place call.
+ (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
+ (Freeze_Subprogram): Code cleanup. Remove all the code that register the
+ primitive in the dispatch tables. This work is now done by Make_DT when
+ the type is frozen.
+ (Register_Predefined_DT_Entry): Removed.
+ (Add_Return): If end label is not present, use sloc of last statement
+ for generated return statement in procedure, for better gdb behavior
+ on expanded code.
+ (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
+ object address nodes to ensure proper processing by routines like
+ Insert_After*.
+ (Expand_Call): Fix generation of validity check for parameter
+ (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
+ the allocation form parameter if the result subtype is constrained,
+ except when the function has a controlling result.
+ (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
+ rather than Is_Controlled and Has_Controlled_Component, since we want to
+ include class-wide result types in this treatment. Also test for a
+ controlling result, since that also requires passing a finalization
+ list.
+ (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
+ even when the result subtype is constrained, to handle calls involving
+ controlling results.
+ (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
+ is now called even when the result subtype is constrained, to handle
+ calls involving controlling results.
+ (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
+ on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
+ now performs the test).
+ (Make_Build_In_Place_Call_In_Object_Declaration):
+ Add_Alloc_Form_Actual_* is now called even when the result subtype is
+ constrained, to handle calls involving controlling results.
+ (Add_Return): Accomodate rewritten pattern from local raise to goto
+ transformation, so that we still recognize an transfer statement
+ and do the right thing here in that case.
+ (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
+ and end of subprogram code.
+ (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
+ support for primitives that are functions (without formals) with a
+ controlling result.
+ (Inherited_From_Formal): If the actual subtype has not generic parent
+ type, it is not an actual for a formal derived type, and there is no
+ operation to inherit from the formal.

+ (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
+ Raise_From_Controlled_Operation is available, use a call to that
+ subprogram instead of a plain "raise Program_Error" node to raise
+ Program_Error if an exception is propagated from an Adjust or Finalize
+ operation.
+ (Insert_Actions_In_Scope_Around): If the statement to be wrapped
+ appears in the optional statement list of a triggering alternative, the
+ scope actions can be inserted directly there, and not in the list that
+ includes the asynchronous select itself.

+
+ * exp_intr.adb (Expand_Unc_Deallocation): Add missing support for
+ deallocation of class-wide interface objects.
+ (Expand_Dispatching_Constructor_Call): Take into account that if the
+ result of the dispatching constructor is an interface type, the
+ function returns a class-wide interface type; otherwise the returned
+ object would be actual. The frontend previously accepted returning
+ interface types because Expand_Interface_Actuals silently performed
+ the management of the returned type "as if" it were a class-wide

+ (Create_Packed_Array_Type): Set proper Esize value adjusted as required
+ to match the alignment.
+ (Create_Packed_Array_Type): Use Short_Short_Unsigned as base type for

+
+ * freeze.adb (Freeze_Entity): When freezing the formals of a

+ (Freeze_Record_Type): Check for bad discriminated record convention
+ (In_Exp_Body): Return true if the body is generated for a subprogram
+ renaming, either an attribute renaming or a renaming as body.
+ (Check_Itype): If the designated type of an anonymous access component
+ is a non-protected subprogram type, indicate that it is frozen, to
+ prevent out-of-scope freeze node at some subsequent call.
+ (Freeze_Subprogram): On OpenVMS, reject descriptor passing mechanism
+ only if the subprogram is neither imported nor exported, as well as the

+
+ * exp_util.ads, exp_util.adb (Expand_Subtype_From_Expr): In Ada2005, an

+ and the underlying type is a constrained composite type, build an actual
+ subtype from the function call, as is done for private types.
+ (Side_Effect_Free): An expression that is the renaming of an object or
