* exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
Is_Inherently_Limited_Type, because return-by-reference has no meaning
in Ada 2005.
(Find_Node_To_Be_Wrapped): Use new method of determining the result
type of the function containing a return statement, because the
Return_Type field was removed. We now use the Return_Applies_To field.
* exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
(Build_Task_Image_Decl): If procedure is not called from an
initialization procedure, indicate that function that builds task name
uses the sec. stack. Otherwise the enclosing initialization procedure
will carry the indication.
(Insert_Actions): Remove N_Return_Object_Declaration. We now use
N_Object_Declaration instead.
(Kill_Dead_Code): New interface to implement -gnatwt warning for
conditional dead code killed, and change implementation accordingly.
(Insert_Actions): Add N_Return_Object_Declaration case.
Correct comment to mention N_Extension_Aggregate node.
(Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
attempts to save information for global variables which cannot be
safely tracked.
(Get_Current_Value_Condition): Handle conditions the other way round
(constant on left). Also handle right operand of AND and AND THEN
(Set_Current_Value_Condition): Corresponding changes
(Append_Freeze_Action): Remove unnecessary initialization of Fnode.
(Get_Current_Value_Condition): Handle simple boolean operands
(Get_Current_Value_Condition): Handle left operand of AND or AND THEN
(Get_Current_Value_Condition): If the variable reference is within an
if-statement, does not appear in the list of then_statments, and does
not come from source, treat it as being at unknown location.
(Get_Current_Value_Condition): Enhance to allow while statements to be
processed as well as if statements.
(New_Class_Wide_Subtype): The entity for a class-wide subtype does not
come from source.
(OK_To_Do_Constant_Replacement): Allow constant replacement within body
of loop. This is safe now that we fixed Kill_Current_Values.
(OK_To_Do_Constant_Replacement): Check whether current scope is
Standard, before examining outer scopes.
