| | | | | | | | | | | | | | | | | | | | | | | | * sem_ch12.adb (Instantiate_Formal_Subprogram): In the subprogram renaming declaration, use the Slocs of the formal parameters from the declaration of the formal subprogram when creating the formal parameter entities in the renaming declaration. (Analyze_Formal_Type_Declaration): Change the placement of the error message concerning illegal known discriminants. It is now posted on the type rather than on the first discriminant. This change ensures early error report. (Freeze_Subprogram_Body): If the generic subprogram is nested within the package body that contains the instance, do not generate an out-of-place freeze node for the enclosing package. (Collect_Previous_Instantiations): Ignore internal instantiations generated for formal packages. (Validate_Derived_Type_Instance): Add a check that when a formal derived type is Known_To_Have_Preelab_Init then the actual type must have preelaborable initialization, and issue an error when this condition is violated. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@130851 138bc75d-0d04-0410-961f-82ee72b054a4

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Gary Dismukes <dismukes@adacore.com> Thomas Quinot <quinot@adacore.com> * sem_ch12.ads, sem_ch12.adb (Instantiate_Type): If the formal is a derived type with interface progenitors use the analyzed formal as the parent of the actual, to create renamings for all the inherited operations in Derive_Subprograms. (Collect_Previous_Instances): new procedure within of Load_Parent_Of_Generic, to instantiate all bodies in the compilation unit being loaded, to ensure that the generation of global symbols is consistent in different compilation modes. (Is_Tagged_Ancestor): New function testing the ancestor relation that takes progenitor types into account. (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by traversing over the primitives of the formal and actual types to locate any abstract subprograms of the actual type that correspond to a nonabstract subprogram of the formal type's ancestor type(s), and issue an error if such is found. (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation, Instantiate_Package_Body, Instantiate_Subprogram_Body): Remove bogus guard around calls to Inherit_Context. (Reset_Entity): If the entity is the selector of a selected component that denotes a named number, propagate constant-folding to the generic template only if the named number is global to the generic unit. (Set_Instance_Env): Only reset the compilation switches when compiling a predefined or internal unit. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@127443 138bc75d-0d04-0410-961f-82ee72b054a4

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Javier Miranda <miranda@adacore.com> * sem_ch12.adb (Analyze_Associations): Diagnose use of an others association in an instance. (Copy_Generic_Node): If the node is a string literal, no need to copy its descendants. (Is_Generic_Formal): For a formal subprogram, the declaration is the grandparent of the entity. (Analyze_Formal_Interface_Type): Transform into a full type declaration, to simplify handling of formal interfaces that derive from other formal interfaces. (Instantiate_Subprogram_Body): The defining unit name of the body of the instance should be a defining identifier. (Install_Formal_Packages): make global to the package, for use in instantiations of child units. (Analyze_Package_Instantiation): Do not attempt to set information on an enclosing master of an entry when expansion is disabled. (Instantiate_Type): If the actual is a tagged synchronized type and the generic ancestor is an interface, create a generic actual for the corresponding record. (Analyze_Formal_Derived_Interface_Type): Rewrite as a derived type declaration, to ensure that the interface list is processed correctly. (Inline_Instance_Body): If enclosing scope is an instance body, remove its entities from visibiility as well. (Pre_Analyze_Actuals): if the actual is an allocator with constraints given with a named association, analyze the expression only, not the discriminant association itself. (Reset_Entity): If the analysis of a selected component is transformed into an expanded name in the prefix of a call with parameters, do not transform the original node into an expanded name, to prevent visibility errors in the case of nested generics. (Check_Private_View): For an array type, check whether the index types may need exchanging. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@125431 138bc75d-0d04-0410-961f-82ee72b054a4

(Analyze_Formal_Object_Declaration): Add check for illegal default expressions for a formal in object of a limited type. (Instantiate_Object): Ditto. (Check_Formal_Package_Instance): Skip entities that are formal objects, because they were defaulted in the formal package and no check applies to them. (Check_Formal_Package_Instance): Extend conformance check to other discrete types beyond Integer. (Process_Default): Copy directly the unmatched formal. A generic copy has already been performed in Analyze_Formal_Package. (Analyze_Associations): If a formal subprogram has no match, check for partial parametrization before looking for a default, to prevent spurious errors. (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do not set the instantiation environment before analyzing the actuals. Fixes regression on 8515-003 with implementation of AI-133. Set_Instance_Env checks whether the generic unit is a predefined unit, in which case the instance must be analyzed with the latest Ada mode. This setting must take place after analysis of the actuals, because the actuals must be analyzed and frozen in the Ada mode extant outside of the current instantiation. (Save_Env, Restore_Env): Preserve and restore the configuration parameters so that predefined units can be compiled in the proper Ada mode. (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram, Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type. (Analyze_Formal_Package): For better error recovery, Add exception handler to catch Instantion_Error, which can be raised in Analyze_Associations git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@123593 138bc75d-0d04-0410-961f-82ee72b054a4

(Analyze_Formal_Derived_Type): Set the limited present flag of the newly generated private extension declaration if the formal derived type is synchronized. Carry synchronized present over to the generated private extension. (Validate_Derived_Type_Instance): Ensure that the actual of a synchronized formal derived type is a synchronized tagged type. (Instantiate_Formal_Package): When creating the instantiation used to validate the actual package of a formal declared without a box, check whether the formal itself depends on a prior actual. (Instantiate_Formal_Subprogram): Create new entities for the defining identifiers of the formals in the renaming declaration, for ASIS use. (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating a renaming declaration or a subtype declaration for an actual in an instance, capture location information of declaration in generic, for ASIS use. (Instantiate_Formal_Package): Add comments on needed additional tests. AI-317 (partial parametrization) is fully implemented. (Validate_Private_Type_Instance): Add check for actual which must have preelaborable initialization Use new // insertion for some continuation messages (Analyze_Formal_Object_Declaration): Change usage of Expression to Default_Expression. Add type retrieval when the declaration has an access definition. Update premature usage of incomplete type check. (Check_Access_Definition): New subsidiary routine. Check whether the current compilation version is Ada 05 and the supplied node has an access definition. (Instantiate object): Alphabetize local variables. Handle the creation of new renaming declarations with respect to the kind of definition used - either an access definition or a subtype mark. Guard against unnecessary error message in the context of anonymous access types after they have been resolved. Add check for required null exclusion in a formal object declaration. (Switch_View): A private subtype of a non-private type needs to be switched (the base type can have been switched without its private dependents because of the last branch of Check_Private_View. (Check_Private_View): Do not recompute Base_Type (T), instead use cached value from BT. (Instantiate_Type): Emit an error message whenever a class-wide type of a tagged incomplete type is used as a generic actual. (Find_Actual_Type): Extend routine to handle a component type in a child unit that is imported from a formal package in a parent. (Validate_Derived_Type_Instance): Check that analyzed formal and actual agree on constrainedness, rather than checking against ultimate ancestor (Instantiate_Subprogram_Body): Create a cross-reference link to the generic body, for navigation purposes. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@118300 138bc75d-0d04-0410-961f-82ee72b054a4

Properly handle Ada_Version_Explicit and Ada_Version_Config, which were not always properly handled previously. (Formal_Entity): Complete rewrite, to handle properly some complex case with multiple levels of parametrization by formal packages. (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator to the corresponding derived type declaration for proper semantics. * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message. (Check_Component): Enforce restriction on components of unchecked_unions: a component in a variant cannot contain tasks or controlled types. (Unchecked_Union): Allow nested variants and multiple discriminants, to conform to AI-216. Add pragma Ada_2005 (synonym for Ada_05) Properly handle Ada_Version_Explicit and Ada_Version_Config, which were not always properly handled previously. Document that pragma Propagate_Exceptions has no effect (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure (Set_Convention_From_Pragma): Check that if a convention is specified for a dispatching operation, then it must be consistent with the existing convention for the operation. (CPP_Class): Because of the C++ ABI compatibility, the programmer is no longer required to specify an vtable-ptr component in the record. For compatibility reasons we leave the support for the previous definition. (Analyze_Pragma, case No_Return): Allow multiple arguments * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a non-overrideen inherited operation with a controlling result as illegal only its implicit declaration comes from the derived type declaration of its result's type. (Check_Possible_Deferred_Completion): Relocate the object definition node of the subtype indication of a deferred constant completion rather than directly analyzing it. The analysis of the generated subtype will correctly decorate the GNAT tree. (Record_Type_Declaration): Check whether this is a declaration for a limited derived record before analyzing components. (Analyze_Component_Declaration): Diagnose record types not explicitly declared limited when a component has a limited type. (Build_Derived_Record_Type): Code reorganization to check if some of the inherited subprograms of a tagged type cover interface primitives. This check was missing in case of a full-type associated with a private type declaration. (Constant_Redeclaration): Check that the subtypes of the partial and the full view of a constrained deferred constant statically match. (Mentions_T): A reference to the current type in an anonymous access component declaration must be an entity name. (Make_Incomplete_Type_Declaration): If type is tagged, set type of class_wide type to refer to full type, not to the incomplete one. (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not available. Required to give support to the certified run-time. (Analyze_Component_Declaration): In case of anonymous access components perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2). (Process_Discriminants): For an access discriminant, use the discriminant specification as the associated_node_for_itype, to simplify accessibility checks. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@111091 138bc75d-0d04-0410-961f-82ee72b054a4

(Analyze_Package_Instantiation): Set the instantiated package entity's Package_Instantiation field. (Get_Package_Instantiation_Node): Move declaration to package spec. Retrieve the N_Package_Instantiation node when the Package_Instantiation field is present. (Check_Generic_Child_Unit): Within an inlined call, the only possible instantiation is Unchecked_Conversion, for which no parents are needed. (Inline_Instance_Body): Deinstall and record the use_clauses for all parent scopes of a scope being removed prior to inlining an instance body. (Analyze_Package_Instantiation): Do not perform front-end inlining when the current context is itself an instance within a non-instance child unit, to prevent scope stack errors. (Save_References): If the node is an aggregate that is an actual in a call, rewrite as a qualified expression to preserve some type information, to resolve possible ambiguities in the instance. (Instance_Parent_Unit): New global variable to record the ultimate parent unit associated with a generic child unit instance (associated with the existing Parent_Unit_Visible flag). (type Instance_Env): New component Instance_Parent_Unit for stacking parents recorded in the global Instance_Parent_Unit. (Init_Env): Save value of Instance_Parent_Unit in the Instance_Env stack. (Install_Spec): Save the parent unit entity in Instance_Parent_Unit when it's not a top-level unit, and only do this if Instance_Parent_Unit is not already set. Replace test of Is_Child_Unit with test of parent's scope against package Standard. Add comments and a ??? comment. (Remove_Parent): Revise condition for resetting Is_Immediately_Visible on a child instance parent to test that the parent equals Instance_Parent rather than simply checking that the unit is not a child unit. (Restore_Env): Restore value of Instance_Parent_Unit from Instance_Env.

(Make_DT): Generate a call to set the accessibility level of the tagged type in its TSD. (Make_DT): Code cleanup. The functionality of generating all the secondary dispatch tables has been moved to freeze_record_type. (Make_Abstract_Interface_DT): Minor code cleanup. (Set_All_DT_Position): Code cleanup. As part of the code cleanup this subprogram implements a new algorithm that provides the same functionality and it is more clear in case of primitives associated with abstract interfaces.

(Build_Derived_Record_Type): Modified to give support to private types implemening interfaces. (Access_Definition): Reject ALL on anonymous access types. (Build_Derived_Record_Type): In the case of Ada 2005, allow a tagged type derivation to occur at a deeper accessibility level than the parent type. For the case of derivation within a generic body however, disallow the derivation if the derived type has an ancestor that is a formal type declared in the formal part of an enclosing generic. (Analyze_Object_Declaration): For protected objects, remove the check that they cannot contain interrupt handlers if not declared at library level.

(Expand_N_Object_Declaration): Do not generate an initialization for a scalar temporary marked as internal. * exp_ch6.adb (Add_Simple_Call_By_Copy_Code): Handle properly an in-out parameter that is a component in an initialization procedure, whose constraint might depend on discriminants, and that may be misaligned because of packing or representation clauses. (Is_Legal_Copy): New predicate to determine whether a possibly misaligned in-out actual can actually be passed by copy/return. This is an error in case the type is by_reference, and a warning if this is the consequence of a DEC import pragma on the subprogram. (Expand_Call, Freeze_Subprogram): Modified to give support to abstract interface types (Expand_Inlined_Call): Mark temporary generated for the return value as internal, so that no useless scalar normalization is generated for it. (Expand_N_Subprogram_Declaration): Save unanalyzed body so calls to null procedure can always be inlined. (Expand_N_Subprogram_Declaration): If this is the declaration of a null procedure, generate an explicit empty body for it. * exp_util.ads, exp_util.adb (Find_Interface_ADT): New subprogram. Given a type implementing an interface, returns the corresponding access_disp_table value. (Find_Interface_Tag): New subprogram. Given a type implementing an interface, returns the record component containing the tag of the interface. (Find_Interface_Tag): New overloaded subprogram. Subsidiary to the previous ones that return the corresponding tag and access_disp_table entities. (Is_Predefined_Dispatching_Operation): Determines if a subprogram is a predefined primitive operation.

(Has_Interface_Formals): New subprogram subsidiary to analyze subprogram_specification that returns true if some non class-wide interface subprogram is found (New_Overloaded_Entity): Modified to give support to abstract interface types (Conforming_Types): In Ada 2005 mode, conformance checking of anonymous access to subprograms must be recursive. (Is_Unchecked_Conversion): Improve the test that recognizes instantiations of Unchecked_Conversion, and allows them in bodies that are to be inlined by the front-end. When the body comes from an instantiation, a reference to Unchecked_Conversion will be an Expanded_Name, even though the body has not been analyzed yet. Replace Is_Overriding and Not_Overriding in subprogram_indication with Must_Override and Must_Not_Override, to better express intent of AI. (Analyze_Subprogram_Body): If an overriding indicator is given, check that it is consistent with the overrinding status of the subprogram at this point. (Analyze_Subprogram_Declaration): Indicate that a null procedure is always inlined. If the subprogram is a null procedure, indicate that it does not need a completion. * sem_disp.adb (Check_Controlling_Type): Give support to entities available through limited-with clauses. (Check_Dispatching_Operation): A stub acts like a body, and therefore is allowed as the last primitive of a tagged type if it has no previous spec. (Override_Dispatching_Operation, Check_Dispatching_Operation): Modified to give support to abstract interface types * sem_res.adb (Valid_Conversion): Perform an accessibility level check in the case where the target type is an anonymous access type of an object or component (that is, when Is_Local_Anonymous_Access is true). Prevent the special checks for conversions of access discriminants in the case where the discriminant belongs to a nonlimited type, since such discriminants have their accessibility level defined in the same way as a normal component of an anonymous access type. (Resolve_Allocator): When an allocator's designated type is a class-wide type, check that the accessibility level of type given in the allocator's expression or subtype indication is not statically deeper than the level of the allocator's access type. (Check_Discriminant_Use): Diagnose discriminant given by an expanded name in a discriminant constraint of a record component. (Resolve_Explicit_Dereference): Do not check whether the type is incomplete when the dereference is a use of an access discriminant in an initialization procedure. (Resolve_Type_Conversion): Handle conversions to abstract interface types. (Valid_Tagged_Conversion): The conversion of a tagged type to an abstract interface type is always valid. (Valid_Conversion): Modified to give support to abstract interface types (Resolve_Actuals): Enable full error reporting on view conversions between unrelated by_reference array types. The rule for view conversions of arrays with aliased components is weakened in Ada 2005. Call to obsolescent subprogram is now considered to be a violation of pragma Restrictions (No_Obsolescent_Features). (Check_Direct_Boolean_Operator): If the boolean operation has been constant-folded, there is nothing to check. (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer check on possible violation of restriction No_Direct_Boolean_Operators until after expansion of operands, to prevent spurious errors when operation is constant-folded. * sem_type.ads, sem_type.adb (Covers, Intersect_Types, Specific_Type, Has_Compatible_Type): Modified to give support to abstract interface types. (Interface_Present_In_Ancestor): New function to theck if some ancestor of a given type implements a given interface * sem_ch4.adb (Analyze_Call): Handle properly an indirect call whose prefix is a parameterless function that returns an access_to_procedure. (Transform_Object_Operation): Handle properly function calls of the form Obj.Op (X), which prior to analysis appear as indexed components. (Analyze_One_Call): Complete the error notification to help new Ada 2005 users. (Analyze_Allocator): For an allocator without an initial value, where the designated type has a constrained partial view, a discriminant constraint is illegal. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@101024 138bc75d-0d04-0410-961f-82ee72b054a4

Restriction_Warnings now allows full parameter notation Major rewrite of Restrictions for new restrictions handling 2004-02-02 Javier Miranda <miranda@gnat.com> * par-ch3.adb (P_Identifier_Declarations): Give support to the Ada 0Y syntax rule for object renaming declarations. (P_Array_Type_Definition): Give support for the Ada 0Y syntax rule for component definitions. * sem_ch3.adb (Analyze_Component_Declaration): Give support to access components. (Array_Type_Declaration): Give support to access components. In addition it was also modified to reflect the name of the object in anonymous array types. The old code did not take into account that it is possible to have an unconstrained anonymous array with an initial value. (Check_Or_Process_Discriminants): Allow access discriminant in non-limited types. (Process_Discriminants): Allow access discriminant in non-limited types Initialize the new Access_Definition field in N_Object_Renaming_Decl node. Change Ada0Y to Ada 0Y in comments * sem_ch4.adb (Find_Equality_Types): Allow anonymous access types in equality operators. Change Ada0Y to Ada 0Y in comments * sem_ch8.adb (Analyze_Object_Renaming): Give support to access renamings Change Ada0Y to Ada 0Y in comments * sem_type.adb (Find_Unique_Type): Give support to the equality operators for universal access types Change Ada0Y to Ada 0Y in comments * sinfo.adb (Access_Definition, Set_Access_Definition): New subprograms * sinfo.ads (N_Component_Definition): Addition of Access_Definition field.

The later is kept for backward compatibility. 2004-02-02 Ed Schonberg <schonberg@gnat.com> * lib.ads, i-cobol.ads, * s-stoele.ads, s-thread.ads, style.ads, 5staprop.adb, atree.adb, atree.ads, g-crc32.ads: Remove redundant pragma and fix incorrect ones. * sem_prag.adb For pragma Inline and pragma Pure_Function, emit a warning if the pragma is redundant. 2004-02-02 Thomas Quinot <quinot@act-europe.fr> * 5staprop.adb: Add missing 'constant' keywords. * Makefile.in: use consistent value for SYMLIB on platforms where libaddr2line is supported. 2004-02-02 Richard Kenner <kenner@vlsi1.ultra.nyu.edu> * utils.c (end_subprog_body): Do not call rest_of_compilation if just annotating types. 2004-02-02 Olivier Hainque <hainque@act-europe.fr> * init.c (__gnat_install_handler): Setup an alternate stack for signal handlers in the environment thread. This allows proper propagation of an exception on stack overflows in this thread even when the builtin ABI stack-checking scheme is used without support for a stack reserve region. * utils.c (create_field_decl): Augment the head comment about bitfield creation, and don't account for DECL_BIT_FIELD in DECL_NONADDRESSABLE_P here, because the former is not accurate enough at this point. Let finish_record_type decide instead. Don't make a bitfield if the field is to be addressable. Always set a size for the field if the record is packed, to ensure the checks for bitfield creation are triggered. (finish_record_type): During last pass over the fields, clear DECL_BIT_FIELD when possible in the !STRICT_ALIGNMENT case, as this is not covered by the calls to layout_decl. Adjust DECL_NONADDRESSABLE_P from DECL_BIT_FIELD. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@77110 138bc75d-0d04-0410-961f-82ee72b054a4
