Remove the entry for Refined_State. * einfo.ads Add new attributes Encapsulating_State and Part_Of_Constituents alond with their usage in entities. Remove attribute Refined_State along with its usage in entities. (Encapsulating_State): New routine and pragma Inline. (Get_Pragma): Update the comment on usage. (Part_Of_Constituents): New routine and pragma Inline. (Refined_State): Removed along with pragma Inline. (Set_Encapsulating_State): New routine and pragma Inline. (Set_Part_Of_Constituents): New routine and pragma Inline. (Set_Refined_State): Removed along with pragma Inline. * par-prag.adb Pragma Part_Of does not need any special processing by the parser. * sem_ch3.adb (Analyze_Declarations): Remove local variables Body_Id and Prag. Call separate routines to analyze the contract of a package [body]. (Analyze_Object_Contract): Update the comment on usage. Remove local variables Items and Nam. Use Get_Pragma rather than traversing the classification list. Verify whether the lack of indicator Part_Of agrees with the placement of the variable in state space. (Analyze_Object_Declaration): Initialize the encapsulating state of a variable. (Requires_State_Refinement): Moved to sem_util. * sem_ch7.adb (Analyze_Package_Body_Contract): New routine. (Analyze_Package_Contract): New routine. * sem_ch7.ads (Analyze_Package_Body_Contract): New routine. (Analyze_Package_Contract): New routine. * sem_ch10.adb (Decorate_State): Initialize the encapsulating state and Part_Of constituents. * sem_ch13.adb (Analyze_Aspect_Specifications): Add processing for aspect Part_Of. Update all calls to Decorate_Delayed_Aspect_And_Pragma. (Check_Aspect_At_Freeze_Point): Aspect Part_Of does not need any special processing at freeze time. (Decorate_Delayed_Aspect_And_Pragma): Renamed to Decorate_Aspect_And_Pragma. Add formal parameter Delayed and update the associated comment. * sem_prag.adb Add an entry for pragma Part_Of in table Sig_Flags. (Analyze_Abstract_State): Add new global variable State_Id. Remove local constants Errors and Loc. Remove local variables Is_Null and State_Nam. Create the entity of the abstract state on the spot, before all remaining checks are performed. Verify that a missing Part_Of option agrees with the placement of the abstract state within the state space. (Analyze_Depends_In_Decl_Part): Add new global variables Constits_Seen and States_Seen. Check that a state and a corresponding constituent do not appear in pragma [Refined_]Depends. (Analyze_Global_In_Decl_Part): Add new global variables Constits_Seen and States_Seen. Check that a state and a corresponding constituent do not appear in pragma [Refined_]Global. (Analyze_Global_Item): Remove the now obsolete code that deals with Part_Of. Add the entity of the global item to the list of processed items. (Analyze_Initializes_In_Decl_Part): Add new global variables Constits_Seen and States_Seen. Check that a state and a corresponding constituent do not appear in pragma Initializes. (Analyze_Initialization_Item): Add the entity of the initialization item to the list of processed items. (Analyze_Input_Item): Add the entity of the initialization item to the list of processed items. (Analyze_Input_Output): Remove the now obsolete code that deals with Part_Of. Add the entity of the input/output to the list of processed items. (Analyze_Part_Of): New routine. (Analyze_Part_Of_Option): Remove local constant Par_State. Add local constant Encaps and local variables Encaps_Id and Legal. Use Analyze_Part of to analyze the option. Turn the related state into a Part_Of constituent if the option is legal. (Analyze_Pragma): Add processing for pragma Part_Of. (Analyze_Refined_State_In_Decl_Part): Remove global constants Pack_Body and Spec_Id. Remove global variables Abstr_States and Hidden_States. Add new global variables Available_States, Body_Id, Body_States and Spec_Id. Add new local constant Body_Decl. Reimplement the logic that extracts the states available for refinement from the related package and the body hidden states of the said package. (Analyze_Refinement_Clause): Add local variable Part_Of_Constits. (Check_Applicable_Policy): Alphabetize body. (Check_Dependency_Clause): Replace Refined_State with Encapsulating_State. (Check_Matching_Constituent): Reimplement the logic that determines whether an item is a valid / invalid constituent of the current refined state. Return when a construct does not denote a valid abstract state. Extract the list of Part_Of constituents for further analysis. Check that all Part_Of constituents of a state have been used in its refinement. (Check_Matching_State): Update the comment on usage. Operate on the list of available states. (Check_Missing_Part_Of): New routine. (Check_Refined_Global_Item): Replace Refined_State with Encapsulating_State. (Check_State_And_Constituent_Use): New routine. (Create_Abstract_State): New routine. (Is_Matching_Input): Replace Refined_State with Encapsulating_State. (Is_Part_Of): Removed. (Collect_Body_States): New routine.

(Find_Placement_In_State_Space): New routine. (Is_Child): Removed. (Is_Child_Or_Sibling): Remove formal parameter Private_Child. Remove the private child checks. (Requires_State_Refinement): Moved from sem_ch3. * sem_util.ads Add new type State_Space_Kind along with comment on its usage and values. (Add_Contract_Item): Update the comment on usage. (Find_Body_Discriminal): Alphabetize spec. (Find_Placement_In_State_Space): New routine. (Is_Child_Or_Sibling): Remove formal parameter Private_Child and update the comment on usage. (Requires_State_Refinement): Moved from sem_ch3. * sinfo.ads: Update the documentation of N_Contract. * snames.ads-tmpl The predefined name for Part_Of is now used to denote a pragma. Add Pragma_Id for Part_Of. From-SVN: r207251
