-
--- Available_View (synthesized)
--- Applies to types that have the With_Type flag set. Returns the
--- non-limited view of the type, if available, otherwise the type

-
-- Enclosing_Scope (Node18)

-- Extra_Formals (Node28)
-- Applies to subprograms and subprogram types, and also in entries
-- or entry. Returns Empty if there are no extra formals.
-- Extra_Accessibility (Node13)
--- Present in formal parameters in the non-generic case if
--- expansion is active. Normally Empty, but if a parameter is
--- one for which a dynamic accessibility check is required, then
--- an extra formal of type Natural is created (see description
--- of field Extra_Formal), and the Extra_Accessibility field of
--- the formal parameter points to the entity for this extra

-- Extra_Constrained (Node23)
--- Present in formal parameters in the non-generic case if
--- expansion is active. Normally Empty, but if a parameter is
--- one for which a dynamic indication of its constrained status
--- is required, then an extra formal of type Boolean is created
--- (see description of field Extra_Formal), and the

+
+-- Can_Use_Internal_Rep (Flag229) [base type only]
+-- Present in Access_Subprogram_Kind nodes. This flag is set by the
+-- front end and used by the back end. False means that the back end
+-- must represent the type in the same way as Convention-C types (and
+-- other foreign-convention types). On many targets, this means that
+-- the back end will use dynamically generated trampolines for nested
+-- subprograms. True means that the back end can represent the type in
+-- some internal way. On the aforementioned targets, this means that the
+-- back end will not use dynamically generated trampolines. This flag
+-- must be False if Has_Foreign_Convention is True; otherwise, the front
+-- end is free to set the policy.
+--
+-- Setting this False in all cases corresponds to the traditional back
+-- end strategy, where all access-to-subprogram types are represented the
+-- same way, independent of the Convention. See also
+-- Always_Compatible_Rep in Targparm.
+--
+-- Efficiency note: On targets that use dynamically generated
+-- trampolines, False generally favors efficiency of top-level
+-- subprograms, whereas True generally favors efficiency of nested
+-- ones. On other targets, this flag has little or no effect on
+-- efficiency. The front end should take this into account. In
+-- particular, pragma Favor_Top_Level gives a hint that the flag should
+-- be False.
+--
+-- Note: We considered using Convention-C for this purpose, but we need
+-- this separate flag, because Convention-C implies that for
+-- P'[Unrestricted_]Access, P also have convention C. Sometimes we want
+-- to have Can_Use_Internal_Rep False for an access type, but allow P to
+-- have convention Ada.
-- Finalization_Chain_Entity (Node19)
-- Present in scopes that can have finalizable entities (blocks,
-- Similar to First_Component, but discriminants are not skipped, so will
-- find the first discriminant if discriminants are present.
--- First_Discriminant (synthesized)
--- Applies to types with discriminants. The discriminants are the first
--- entities declared in the type, so normally this is equivalent to
--- First_Entity. The exception arises for tagged types, where the tag
--- itself is prepended to the front of the entity chain, so the
--- First_Discriminant function steps past the tag if it is present.
-
-- First_Entity (Node17)
-- Present in all entities which act as scopes to which a list of
-- associated entities is attached (blocks, class subtypes and types,
-- corresponding to the specified parameter.
-- First_Private_Entity (Node16)
--- Present in all entities containing private parts (packages,
--- protected types and subtypes, task types and subtypes). The
--- entities on the entity chain are in order of declaration, so the
--- entries for private entities are at the end of the chain. This
--- field points to the first entity for the private part. It is
--- Empty if there are no entities declared in the private part or

+-- Present in all entities containing private parts (packages, protected
+-- types and subtypes, task types and subtypes). The entities on the
+-- entity chain are in order of declaration, so the entries for private
+-- entities are at the end of the chain. This field points to the first
+-- entity for the private part. It is Empty if there are no entities
+-- declared in the private part or if there is no private part.
-- First_Rep_Item (Node6)
-- Present in all entities. If non-empty, points to a linked list of
-- kind of rep item on the chain, in which case it is the first one
-- that applies to the entity.
--
+-- Note: pragmas that can apply to more than one overloadable entity,
+-- (Convention, Interface, Inline, Inline_Always, Import, Export,
+-- External) are never present on this chain when they apply to
+-- overloadable entities, since it is impossible for a given pragma
+-- to be on more than one chain at a time.
+--
-- For most representation items, the representation information is
--- reflected in other fields and flags in the entity. For example if
--- a record representation clause is present, the component entities

--
-- Alignment attribute definition clause
-- Machine_Attribute pragma
-- Note in particular that size clauses are present only for this
-- purpose, and should only be accessed if Has_Size_Clause is set.
--- First_Stored_Discriminant (synthesized)
--- Applies to types with discriminants. Gives the first discriminant
--- stored in the object. In many cases, these are the same as the
--- normal visible discriminants for the type, but in the case of
--- renamed discriminants, this is not always the case.
---
--- For tagged types, and untagged types which are root types or
--- derived types but which do not rename discriminants in their
--- root type, the stored discriminants are the same as the actual
--- discriminants of the type, and hence this function is the same
--- as First_Discriminant.
---
--- For derived non-tagged types that rename discriminants in the root
--- type this is the first of the discriminants that occur in the
--- root type. To be precise, in this case stored discriminants are
--- entities attached to the entity chain of the derived type which
--- are a copy of the discriminants of the root type. Furthermore their
--- Is_Completely_Hidden flag is set since although they are actually
--- stored in the object, they are not in the set of discriminants that
--- is visble in the type.
---
--- For derived untagged types, stored discriminants are the real
--- discriminants from Gigi's standpoint, i.e. those that will be
--- stored in actual objects of the type.
-
--- First_Subtype (synthesized)
--- Applies to all types and subtypes. For types, yields the first
--- subtype of the type. For subtypes, yields the first subtype of
--- the base type of the subtype.
-
--- First_Tag_Component (synthesized)
--- Applies to tagged record types, returns the entity for the first
--- _Tag field in this record.
-
-- Freeze_Node (Node7)
-- Present in all entities. If there is an associated freeze node for
-- the entity, this field references this freeze node. If no freeze
-- For all types other than private and incomplete types, this field
-- always contains Empty. See also Underlying_Type.
--- Function_Returns_With_DSP (Flag169)
--- Present in all subprogram entities, and type entities for access
--- to subprogram values. Set True if the function (or referenced
--- function in the case of an access value) returns with using the
--- DSP (depressed stack pointer) approach. This can only be set
--- True if Targparm.Functions_Return_By_DSP_On_Target is True and
--- the function returns a value of a type whose size is not known
--- at compile time.
---
--- Note: this flag is obsolete, it is always False ???
-
-- Generic_Homonym (Node11)
-- Present in generic packages. The generic homonym is the entity of
-- a renaming declaration inserted in every generic unit. It is used
-- reduce the required size. For example, a type with a range of 1..2
-- takes one bit, using 0 to represent 1 and 1 to represent 2.
--
--- Note that in the object and component cases, the flag is only set
--- if the type is unbiased, but the object specifies a smaller size
--- than the size of the type, forcing biased representation for the
--- object, but the subtype is still an unbiased type.
+-- Note that in the object and component cases, the flag is only set if

-- Has_Completion (Flag26)
-- Present in all entities that require a completion (functions,
-- or Is_Controlled is set for at least one component).
-- Has_Convention_Pragma (Flag119)
--- Present in an entity for which a Convention, Import, or Export
--- pragma has been given. Used to prevent more than one such pragma
--- appearing for a given entity (RM B.1(45)).
+-- Present in all entities. Set true for an entity for which a valid
+-- Convention, Import, or Export pragma has been given. Used to prevent

-- Has_Delayed_Freeze (Flag18)
-- Present in all entities. Set to indicate that an explicit freeze
-- and incomplete types), indicates if the corresponding type or subtype
-- has a known discriminant part. Always false for all other types.
+-- Has_Dispatch_Table (Flag220)
+-- Present in E_Record_Types that are tagged. Set to indicate that the
+-- corresponding dispatch table is already built. This flag is used to
+-- avoid duplicate construction of library level dispatch tables (because
+-- the declaration of library level objects cause premature construction
+-- of the table); otherwise the code that builds the table is added at
+-- the end of the list of declarations of the package.
+
-- Has_Entries (synthesized)
-- Applies to concurrent types. True if any entries are declared
-- within the task or protected definition for the type.
-- linear elaboration of front-end inlining.
-- Has_Fully_Qualified_Name (Flag173)
--- Present in all entities. Set True if the name in the Chars field

--
-- Machine_Attribute pragma
-- Linker_Alias pragma
-- Has_Homonym (Flag56)
-- Present in all entities. Set if an entity has a homonym in the same
-- scope. Used by Gigi to generate unique names for such entities.
-
+--
+-- Has_Initial_Value (Flag219)
+-- Present in entities for variables and out parameters. Set if there
+-- is an explicit initial value expression in the declaration of the
+-- variable. Note that this is set only if this initial value is
+-- explicit, it is not set for the case of implicit initialization

--- declared in a local procedure p and is accessed in a procedure nested
--- inside p. Only set when VM_Target /= No_VM currently.
+-- Present in E_Variable and E_Constant entities. Set if the entity
+-- is a local variable declared in a subprogram p and is accessed in

+-- makes use of it to generate proper code for up-level references.
-- Has_Nested_Block_With_Handler (Flag101)
-- Present in scope entities. Set if there is a nested block within the
-- to which the pragma applies, as well as the unit entity itself, for

-- RM_Size (Uint13)
-- Present in all type and subtype entities. Contains the value of
-- type of the class covered by the CW type, otherwise returns the
-- ultimate derivation ancestor of the given type. This function
-- preserves the view, i.e. the Root_Type of a partial view is the
--- partial view of the ulimate ancestor, the Root_Type of a full view
+-- partial view of the ultimate ancestor, the Root_Type of a full view
-- is the full view of the ultimate ancestor. Note that this function
-- does not correspond exactly to the use of root type in the RM, since
-- in the RM root type applies to a class of types, not to a type.
-- the Scope will be the parent package, and for a non-child package,
-- the Scope will be Standard.
--- Scope_Depth (synth)
+-- Scope_Depth (synthesized)
-- Applies to program units, blocks, concurrent types and entries,
-- and also to record types, i.e. to any entity that can appear on
-- the scope stack. Yields the scope depth value, which for those
-- standard format list (i.e. First (Shadow_Entities) is the first
-- entry and subsequent entries are obtained using Next.
--- Shared_Var_Assign_Proc (Node22)
--- Present in variables. Set non-Empty only if Is_Shared_Passive is
--- set, in which case this is the entity for the shared memory assign
--- routine. See Exp_Smem for full details.
-
--- Shared_Var_Read_Proc (Node15)

+-- System.Shared_Storage.Shared_Var_Procs. See Exp_Smem for full details.
-- Size_Check_Code (Node19)
-- Present in constants and variables. Normally Empty. Set if code is
-- size of objects of the type is known at compile time. This flag is
-- used to optimize some generated code sequences, and also to enable
-- some error checks (e.g. disallowing component clauses on variable
--- length objects. It is set conservatively (i.e. if it is True, the
+-- length objects). It is set conservatively (i.e. if it is True, the
-- size is certainly known at compile time, if it is False, then the
-- size may or may not be known at compile time, but the code will
-- assume that it is not known).
-- case where there is a separate spec, where this field references
-- the corresponding parameter entities in the spec.
+-- Spec_PPC_List (Node24)
+-- Present in subprogram and generic subprogram entities. Points to a
+-- list of Precondition and Postcondition pragma nodes for preconditions
+-- and postconditions declared in the spec. The last pragma encountered
+-- is at the head of this list, so it is in reverse order of textual
+-- appearance.
+
-- Storage_Size_Variable (Node15) [implementation base type only]
-- Present in access types and task type entities. This flag is set
-- if a valid and effective pragma Storage_Size applies to the base
-- or a copy of the low bound of the index base type if not.
-- Suppress_Elaboration_Warnings (Flag148)
--- Present in all entities, relevant only for subprogram entities and
+-- Present in all entities, can be set only for subprogram entities and
-- for variables. If this flag is set then Sem_Elab will not generate
-- elaboration warnings for the subprogram or variable. Suppression of
-- such warnings is automatic for subprograms for which elaboration
-- checks associated with declared volatile variables, but if the test
-- is for the purposes of suppressing optimizations, then the front
-- end should test Treat_As_Volatile rather than Is_Volatile.
+--
+-- Note: before testing Treat_As_Volatile, consider whether it would
+-- be more appropriate to use Exp_Util.Is_Volatile_Reference instead,
+-- which catches more cases of volatile references.
-- Type_High_Bound (synthesized)
-- Applies to scalar types. Returns the tree node (Node_Id) that contains
-- private completion. If Td is already constrained, then its full view
-- can serve directly as the full view of T.
+-- Underlying_Record_View (Node24)
+-- Present in record types. Set for record types that are extensions of
+-- types with unknown discriminants, and also set for internally built
+-- underlying record views to reference its original record type. Record
+-- types that are extensions of types with unknown discriminants do not
+-- have a completion, but they cannot be used without having some
+-- discriminated view at hand. This view is a record type with the same
+-- structure, whose parent type is the full view of the parent in the
+-- original type extension.
+
-- Underlying_Type (synthesized)
-- Applies to all entities. This is the identity function except in the
-- case where it is applied to an incomplete or private type, in which
-- is identified. This field is used to generate a warning message if
-- necessary (see Sem_Warn.Check_Unset_Reference).
+-- Used_As_Generic_Actual (Flag222)
+-- Present in all entities, set if the entity is used as an argument to
+-- a generic instantiation. Used to tune certain warning messages.
+
-- Uses_Sec_Stack (Flag95)
-- Present in scope entities (blocks,functions, procedures, tasks,
-- entries). Set to True when secondary stack is used in this scope and
-- must be released on exit unless Sec_Stack_Needed_For_Return is set.
-- Vax_Float (Flag151) [base type only]
--- Present in all type entities. Set only on the base type of float
--- types with Vax format. The particular format is determined by the
--- Digits_Value value which is 6,9,15 for F_Float, D_Float, G_Float.
+-- Present in all type and subtype entities. Set only on the base type of
+-- float types with Vax format. The particular format is determined by
+-- the Digits_Value value which is 6,9,15 for F_Float, D_Float, G_Float.
-- Warnings_Off (Flag96)
-- Present in all entities. Set if a pragma Warnings (Off, entity-name)
-- is used to suppress warnings for a given entity. It is also used by
--- the compiler in some situations to kill spurious warnings.
+-- the compiler in some situations to kill spurious warnings. Note that
+-- clients should generally not test this flag directly, but instead
+-- use function Has_Warnings_Off.
+
+-- Warnings_Off_Used (Flag236)
+-- Present in all entities. Can only be set if Warnings_Off is set. If
+-- set indicates that a warning was suppressed by the Warnings_Off flag,
+-- and Unmodified/Unreferenced would not have suppressed the warning.
+
+-- Warnings_Off_Used_Unmodified (Flag237)
+-- Present in all entities. Can only be set if Warnings_Off is set and
+-- Has_Pragma_Unmodified is not set. If set indicates that a warning was
+-- suppressed by the Warnings_Off status but that pragma Unmodified
+-- would also have suppressed the warning.
+
+-- Warnings_Off_Used_Unreferenced (Flag238)
+-- Present in all entities. Can only be set if Warnings_Off is set and
+-- Has_Pragma_Unreferenced is not set. If set indicates that a warning
+-- was suppressed by the Warnings_Off status but that pragma Unreferenced
+-- would also have suppressed the warning.
-- Was_Hidden (Flag196)
-- Present in all entities. Used to save the value of the Is_Hidden
-- attribute when the limited-view is installed (Ada 2005: AI-217).
-- Wrapped_Entity (Node27)
--- Present in an E_Procedure classified as an Is_Primitive_Wrapper. Set
--- to the entity that is being wrapped.
+-- Present in functions and procedures which have been classified as
+-- Is_Primitive_Wrapper. Set to the entity being wrapper.

- -- When a record type with discriminants is processed, the semantic
- -- processing creates the entities for the discriminants. It also creates

-- During expansion of expressions, any discriminant reference is replaced
-- by a reference to the corresponding discriminal. When the initialization
-- have already been replaced by references to these discriminals, which
-- are now the formal parameters corresponding to the required objects.
- -- In the case of a task or protected body, the semantics similarly
- -- creates a set of discriminals for the discriminants of the task or
- -- protected type. When the procedure is created for the task body,
- -- the parameter passed in is a reference to the task value type, which
- -- contains the required discriminant values. The expander creates a

+ -- passed in is a reference to the task value type, which contains the
+ -- required discriminant values. The expander creates a set of declarations
+ -- of the form:
- -- discriminal : constant dtype renames _Task.discriminant;

-- The one bit of trickiness arises in making sure that the right set of

-- processed. Any references to discriminants here are replaced by the
- -- the corresponding *task* discriminals (the record type doesn't even
- -- exist yet, since it is constructed as part of the expansion of the
- -- task declaration, which happens after the semantic processing of the

- ---------------------------------------
- -- Private data in protected objects --
- ---------------------------------------
-
- -- Private object declarations in protected types pose problems
- -- similar to those of discriminants. They are expanded to components
- -- of a record which is passed as the parameter "_object" to expanded
- -- forms of all protected operations. As with discriminants, timing
- -- of this expansion is a problem. The sequence of statements for a
- -- protected operation is expanded before the operation itself, so the
- -- formal parameter for the record object containing the private data
- -- does not exist when the references to that data are expanded.
-
- -- For this reason, private data is handled in the same way as
- -- discriminants, expanding references to private data in protected
- -- operations (which appear as components) to placeholders which will
- -- eventually become renamings of the private selected components
- -- of the "_object" formal parameter. These placeholders are called
- -- "privals", by analogy to the "discriminals" used to implement
- -- discriminants. They are attached to the component declaration nodes
- -- representing the private object declarations of the protected type.
-
- -- As with discriminals, each protected subprogram needs a unique set
- -- of privals, since they must refer to renamings of components of a
- -- formal parameter of that operation. Entry bodies need another set,
- -- which they all share and which is associated with renamings in the
- -- Service_Entries procedure for the protected type (this is not yet
- -- implemented???). This means that we must associate a new set of
- -- privals (and discriminals) with the private declarations after
- -- the body of a protected subprogram is processed.
-
- -- The last complication is the presence of discriminants and discriminated
- -- components. In the corresponding record, the components are constrained
- -- by the discriminants of the record, but within each protected operation
- -- they are constrained by the discriminants of the actual. The actual
- -- subtypes of those components are constructed as for other unconstrained
- -- formals, but the privals are created before the formal object is added
- -- to the parameter list of the protected operation, so they carry the
- -- nominal subtype of the original component. After the protected operation
- -- is actually created (in the expansion of the protected body) we must
- -- patch the types of each prival occurrence with the proper actual subtype
- -- which is by now set. The Privals_Chain is used for this patching.
+ ---------------------------------------------------
+ -- Handling of private data in protected objects --
+ ---------------------------------------------------
+
+ -- Private components in protected types pose problems similar to those
+ -- of discriminants. Private data is visible and can be directly referenced
+ -- from protected bodies. However, when protected entries and subprograms
+ -- are expanded into corresponding bodies and barrier functions, private
+ -- components lose their original context and visibility.
+
+ -- To remedy this side effect of expansion, private components are expanded
+ -- into renamings called "privals", by analogy with "discriminals".
+
+ -- private_comp : comp_type renames _object.private_comp;
+
+ -- Prival declarations are inserted during the analysis of subprogram and
+ -- entry bodies to ensure proper visibility for any subsequent expansion.
+ -- _Object is the formal parameter of the generated corresponding body or
+ -- a local renaming which denotes the protected object obtained from entry
+ -- parameter _O. Privals receive minimal decoration upon creation and are
+ -- categorized as either E_Variable for the general case or E_Constant when
+ -- they appear in functions.
+
+ -- Along with the local declarations, each private component carries a
+ -- placeholder which references the prival entity in the current body. This
+ -- form of indirection is used to resolve name clashes of privals and other
+ -- locally visible entities such as parameters, local objects, entry family
+ -- indexes or identifiers used in the barrier condition.
+
+ -- When analyzing the statements of a protected subprogram or entry, any
+ -- reference to a private component must resolve to the locally declared
+ -- prival through normal visibility. In case of name conflicts (the cases
+ -- above), the prival is marked as hidden and acts as a weakly declared
+ -- entity. As a result, the reference points to the correct entity. When a
+ -- private component is denoted by an expanded name (prot_type.comp for
+ -- example), the expansion mechanism uses the placeholder of the component
+ -- to correct the Entity and Etype of the reference.
