2008-08-04 Javier Miranda <miranda@adacore.com> * sem_ch3.adb (Access_Subprogram_Declaration): Adding missing support for N_Formal_Object_Declaration nodes. Adding kludge required by First_Formal to provide its functionality with access to functions. (Replace_Anonymous_Access_To_Protected_Subprogram): Add missing support for anonymous access types returned by functions. * sem_ch5.adb (Analyze_Assignment): Code cleanup to avoid duplicate conversion of null-excluding access types (required only once to force the generation of the required runtime check). * sem_type.adb (Covers): minor reformating * checks.adb (Null_Exclusion_Static_Checks): Avoid reporting errors with internally generated nodes. Avoid generating the error inside init procs. * sem_res.adb (Resolve_Membership_Test): Minor reformating. (Resolve_Null): Generate the null-excluding check in case of assignment to a null-excluding object. (Valid_Conversion): Add missing support for anonymous access to subprograms. * sem_ch6.adb (Check_Return_Subtype_Indication): Add missing support for anonymous access types whose designated type is an itype. This case occurs with anonymous access to protected subprograms types. (Analyze_Return_Type): Add missing support for anonymous access to protected subprogram. * sem_eval.adb (Subtypes_Statically_Match): In case of access to subprograms addition of missing check on matching convention. Required to properly handle access to protected subprogram types. * exp_ch3 (Build_Assignment): Code cleanup removing duplicated check on null excluding access types. From-SVN: r138610
