| | | | | | | | | | | | | | * exp_aggr.adb (Static_Array_Aggregate): When a static array aggregate with a range is transformed into a positional aggregate, any copied component literals should be marked Is_Static_Expression. * sem_eval.adb (Compile_Time_Known_Value): Don't treat null literals as not being known at at compile time when Configurable_Run_Time_Mode is true. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@139442 138bc75d-0d04-0410-961f-82ee72b054a4

| | | | | | | | | | | | | | | | | | | | | | * exp_aggr.adb (Build_Record_Aggr_Code): Perform a conversion of the target to the type of the aggregate in the case where the target object is class-wide. * exp_ch5.adb (Expand_Simple_Function_Return): When the function's result type is class-wide and inherently limited, and the expression has a specific type, create a return object of the specific type, for more efficient handling of returns of build-in-place aggregates (avoids conversions of the class-wide return object to the specific type on component assignments). * sem_ch6.adb (Check_Return_Subtype_Indication): Suppress the error about a type mismatch for a class-wide function with a return object having a specific type when the object declaration doesn't come from source. Such an object can result from the expansion of a simple return. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@138603 138bc75d-0d04-0410-961f-82ee72b054a4

| | | | | | | | | | | | | | | | | | | * exp_aggr.adb (Expand_Array_Aggregate): If the aggregate contains tasks, create an activation chain now, before the expansion into assignments and build-in-place calls that require the presence of an activation chain. (Backend_Processing_Possible): If the component type is inherently limited, the aggregate must be expanded into individual built-in-place assignments. * sem_ch6.adb (Build_Extra_Formals): Use underlying type of result to determine whether an allocation extra parameter must be built, to handle case of a private type whose full type is a discriminated type with defaults. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@136016 138bc75d-0d04-0410-961f-82ee72b054a4

(Set_Abstract_Interface_Alias): Renamed as Set_Interface_Alias. (Is_Internal): Adding documentation on internal entities that have attribute Interface_Alias (old attribute Abstract_Interface_Alias) * einfo.adb (Abstract_Interface_Alias): Renamed as Interface_Alias. (Set_Abstract_Interface_Alias): Renamed as Set_Interface_Alias. Added assertion to force entities with this attribute to have attribute Is_Internal set to True. (Next_Tag_Component): Simplify assertion using attribute Is_Tag. * sem_ch3.adb (Derive_Interface_Subprograms): This subprogram has been renamed as Derive_Progenitor_Subprograms. In addition, its code is a new implementation. (Add_Interface_Tag_Components): Remove special management of synchronized interfaces. (Analyze_Interface_Declaration): Minor reformating (Build_Derived_Record_Type): Minor reformating (Check_Abstract_Overriding): Avoid reporting error in case of abstract predefined primitive inherited from interface type because the body of internally generated predefined primitives of tagged types are generated later by Freeze_Type (Derive_Subprogram): Avoid generating an internal name if the parent subprogram overrides an interface primitive. (Derive_Subprograms): New implementation that keeps separate the management of tagged types not implementing interfaces, from tagged types that implement interfaces. (Is_Progenitor): New implementation. (Process_Full_View): Add documentation (Record_Type_Declaration): Replace call to Derive_Interface_Subprograms by call to Derive_Progenitor_Subprograms. * sem_ch6.ads (Is_Interface_Conformant): New subprogram. (Check_Subtype_Conformant, Subtype_Conformant): Adding new argument Skip_Controlling_Formals. * sem_ch6.adb (Is_Interface_Conformant): New subprogram. (Check_Conventions): New implementation. Remove local subprogram Skip_Check. Remove formal Search_From of routine Check_Convention. (Check_Subtype_Conformant, Subtype_Conformant): Adding new argument Skip_Controlling_Formals. (New_Overloaded_Entity): Enable addition of predefined dispatching operations. * sem_disp.ads (Find_Primitive_Covering_Interface): New subprogram. * sem_disp.adb (Check_Dispatching_Operation): Disable registering the task body procedure as a primitive of the corresponding tagged type. (Check_Operation_From_Private_Type): Avoid adding twice an entity to the list of primitives. (Find_Primitive_Covering_Interface): New subprogram. (Override_Dispatching_Operation): Add documentation. * sem_type.adb (Covers): Minor reformatings * sem_util.ads (Collect_Abstract_Interfaces): Renamed as Collect_Interfaces. Rename formal. (Has_Abstract_Interfaces): Renamed as Has_Interfaces. (Implements_Interface): New subprogram. (Is_Parent): Removed. (Primitive_Names_Match): New subprogram. (Remove_Homonym): Moved here from Derive_Interface_Subprograms. (Ultimate_Alias): New subprogram. * sem_util.adb (Collect_Abstract_Interfaces): Renamed as Collect_Interfaces. Remove special management for synchronized types. Rename formal. Remove internal subprograms Interface_Present_In_Parent and Add_Interface. (Has_Abstract_Interfaces): Renamed as Has_Interfaces. Replace assertion on non-record types by code to return false in such case. (Implements_Interface): New subprogram. (Is_Parent): Removed. No special management is now required for synchronized types covering interfaces. (Primitive_Names_Match): New subprogram. (Remove_Homonym): Moved here from Derive_Interface_Subprograms. (Ultimate_Alias): New subprogram. * exp_ch3.adb (Add_Internal_Interface_Entities): New subprogram. Add internal entities associated with secondary dispatch tables to the list of tagged type primitives that are not interfaces. (Freeze_Record_Type): Add new call to Add_Internal_Interface_Entities (Make_Predefined_Primitive_Specs): Code reorganization to improve the management of predefined equality operator. In addition, if the type has an equality function corresponding with a primitive defined in an interface type, the inherited equality is abstract as well, and no body can be created for it. * exp_disp.ads (Is_Predefined_Dispatching_Operation): Moved from exp_util to exp_disp. (Is_Predefined_Interface_Primitive): New subprogram. Returns True if an entity corresponds with one of the predefined primitives required to implement interfaces. Update copyright notice. * exp_disp.adb (Set_All_DT_Position): Add assertion. Exclude from the final check on abstract subprograms all the primitives associated with interface primitives because they must be visible in the public and private part. (Write_DT): Use Find_Dispatching_Type to locate the name of the interface type. This allows the use of this routine, for debugging purposes, when the tagged type is not fully decorated. (Is_Predefined_Dispatching_Operation): Moved from exp_util to exp_disp. Factorize code calling new subprogram Is_Predefined_Interface_Primitive. (Is_Predefined_Interface_Primitive): New subprogram. Returns True if an entity corresponds with one of the predefined primitives required to implement interfaces. * exp_util.adb (Find_Interface_ADT): New implementation (Find_Interface): Removed. * sprint.adb (Sprint_Node_Actual): Generate missing output for the list of interfaces associated with nodes N_Formal_Derived_Type_Definition and N_Private_Extension_Declaration. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@135923 138bc75d-0d04-0410-961f-82ee72b054a4

| | | | | | | | | | | * exp_aggr.adb (Not_OK_For_Backend): A component of a private type with discriminants forces expansion of the aggregate into assignments. (Init_Record_Controller): If the type of the aggregate is untagged and is not inherently limited, the record controller is not limited either. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@131071 138bc75d-0d04-0410-961f-82ee72b054a4

| | | | | | | | | | | | | | | | | | | * exp_aggr.adb (Build_Record_Aggr_Code): If there is an aggregate for a limited ancestor part, initialize controllers of enclosing record before expanding ancestor aggregate. (Gen_Assign): If a component of the aggregate is box-initialized, add code to call Initialize if the component is controlled, and explicit assignment of null if the component is an access type. Handle properly aggregates for limited types that appear in object declarations when the aggregate contains controlled values such as protected types. When expanding limited aggregates into individual components, do not call Adjust on controlled components that are limited. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@130828 138bc75d-0d04-0410-961f-82ee72b054a4

Output) becomes available due to Read (resp. Write) being available for the type. Change Boolean variable to the more accurate name Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted double-"not" predicate at beginning of return statement to more understandable form. * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended return has an associated N_Handled_Sequence_Of_Statements, then wrap it in a block statement and use that as the first statement of the expanded return rather than incorrectly using the handled sequence as the first statement. * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected operation, generate an explicit freeze node for it rather than generating extra formals, to ensure that gigi has the proper order of elaboration for anonymous subtypes in the signature of the subprograms. (Build_In_Place_Formal): Move assertion to beginning of loop. (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion applied to a function call (occurs for some cases of 'Input). (Make_Build_In_Place_Call_In_*): Allow for an unchecked conversion applied to a function call (occurs for some cases of 'Input). * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada 2005, generate an extended return statement enclosing the result object and 'Read call. * freeze.adb (Freeze_Record_Type): Extend the current management of components that are access type with an allocator as default value: add missing support to the use of qualified expressions of the allocator (which also cause freezing of the designated type!)
