After considering (and coding) several alternatives, +-- we settled on the present compromise. Things we do not like about +-- this implementation include: + +-- - It is vulnerable to bad Task_ID values, to the extent of +-- possibly trashing memory and crashing the runtime system. + +-- - It requires dynamic storage allocation for each new attribute value, +-- except for types that happen to be the same size as System.Address, +-- or shorter. + +-- - Instantiations at other than the library level rely on being able to +-- do down-level calls to a procedure declared in the generic package body. +-- This makes it potentially vulnerable to compiler changes. + +-- The main implementation issue here is that the connection from +-- task to attribute is a potential source of dangling references. + +-- When a task goes away, we want to be able to recover all the storage +-- associated with its attributes. The Ada mechanism for this is +-- finalization, via controlled attribute types. For this reason, +-- the ARM requires finalization of attribute values when the +-- associated task terminates. + +-- This finalization must be triggered by the tasking runtime system, +-- during termination of the task. Given the active set of instantiations +-- of Ada.Task_Attributes is dynamic, the number and types of attributes +-- belonging to a task will not be known until the task actually terminates. +-- Some of these types may be controlled and some may not. The RTS must find +-- some way to determine which of these attributes need finalization, and +-- invoke the appropriate finalization on them. + +-- One way this might be done is to create a special finalization chain +-- for each task, similar to the finalization chain that is used for +-- controlled objects within the task. This would differ from the usual +-- finalization chain in that it would not have a LIFO structure, since +-- attributes may be added to a task at any time during its lifetime. +-- This might be the right way to go for the longer term, but at present +-- this approach is not open, since GNAT does not provide such special +-- finalization support. + +-- Lacking special compiler support, the RTS is limited to the +-- normal ways an application invokes finalization, i.e. + +-- a) Explicit call to the procedure Finalize, if we know the type +-- has this operation defined on it. This is not sufficient, since +-- we have no way of determining whether a given generic formal +-- Attribute type is controlled, and no visibility of the associated +-- Finalize procedure, in the generic body. + +-- b) Leaving the scope of a local object of a controlled type. +-- This does not help, since the lifetime of an instantiation of +-- Ada.Task_Attributes does not correspond to the lifetimes of the +-- various tasks which may have that attribute. + +-- c) Assignment of another value to the object. This would not help, +-- since we then have to finalize the new value of the object. + +-- d) Unchecked deallocation of an object of a controlled type. +-- This seems to be the only mechanism available to the runtime +-- system for finalization of task attributes. + +-- We considered two ways of using unchecked deallocation, both based +-- on a linked list of that would hang from the task control block. + +-- In the first approach the objects on the attribute list are all derived +-- from one controlled type, say T, and are linked using an access type to +-- T'Class. The runtime system has an Unchecked_Deallocation for T'Class +-- with access type T'Class, and uses this to deallocate and finalize all +-- the items in the list. The limitation of this approach is that each +-- instantiation of the package Ada.Task_Attributes derives a new record +-- extension of T, and since T is controlled (RM 3.9.1 (3)), instantiation +-- is only allowed at the library level. + +-- In the second approach the objects on the attribute list are of +-- unrelated but structurally similar types. Unchecked conversion is +-- used to circument Ada type checking. Each attribute-storage node +-- contains not only the attribute value and a link for chaining, but +-- also a pointer to a descriptor for the corresponding instantiation +-- of Task_Attributes. The instantiation-descriptor contains a +-- pointer to a procedure that can do the correct deallocation and +-- finalization for that type of attribute. On task termination, the +-- runtime system uses the pointer to call the appropriate deallocator. + +-- While this gets around the limitation that instantations be at +-- the library level, it relies on an implementation feature that +-- may not always be safe, i.e. that it is safe to call the +-- Deallocate procedure for an instantiation of Ada.Task_Attributes +-- that no longer exists. In general, it seems this might result in +-- dangling references. + +-- Another problem with instantiations deeper than the library level +-- is that there is risk of storage leakage, or dangling references +-- to reused storage. That is, if an instantiation of Ada.Task_Attributes +-- is made within a procedure, what happens to the storage allocated for +-- attributes, when the procedure call returns? Apparently (RM 7.6.1 (4)) +-- any such objects must be finalized, since they will no longer be +-- accessible, and in general one would expect that the storage they occupy +-- would be recovered for later reuse. (If not, we would have a case of +-- storage leakage.) Assuming the storage is recovered and later reused, +-- we have potentially dangerous dangling references. When the procedure +-- containing the instantiation of Ada.Task_Attributes returns, there +-- may still be unterminated tasks with associated attribute values for +-- that instantiation. When such tasks eventually terminate, the RTS +-- will attempt to call the Deallocate procedure on them. If the +-- corresponding storage has already been deallocated, when the master +-- of the access type was left, we have a potential disaster. This +-- disaster is compounded since the pointer to Deallocate is probably +-- through a "trampoline" which will also have been destroyed. + +-- For this reason, we arrange to remove all dangling references +-- before leaving the scope of an instantiation. This is ugly, since +-- it requires traversing the list of all tasks, but it is no more ugly +-- than a similar traversal that we must do at the point of instantiation +-- in order to initialize the attributes of all tasks. At least we only +-- need to do these traversals if the type is controlled. + +-- We chose to defer allocation of storage for attributes until the +-- Reference function is called or the attribute is first set to a value +-- different from the default initial one. This allows a potential +-- savings in allocation, for attributes that are not used by all tasks. + +-- For efficiency, we reserve space in the TCB for a fixed number of +-- direct-access attributes. These are required to be of a size that +-- fits in the space of an object of type System.Address. Because +-- we must use unchecked bitwise copy operations on these values, they +-- cannot be of a controlled type, but that is covered automatically +-- since controlled objects are too large to fit in the spaces. + +-- We originally deferred the initialization of these direct-access +-- attributes, just as we do for the indirect-access attributes, and +-- used a per-task bit vector to keep track of which attributes were +-- currently defined for that task. We found that the overhead of +-- maintaining this bit-vector seriously slowed down access to the +-- attributes, and made the fetch operation non-atomic, so that even +-- to read an attribute value required locking the TCB. Therefore, +-- we now initialize such attributes for all existing tasks at the time +-- of the attribute instantiation, and initialize existing attributes +-- for each new task at the time it is created. + +-- The latter initialization requires a list of all the instantiation +-- descriptors. Updates to this list, as well as the bit-vector that +-- is used to reserve slots for attributes in the TCB, require mutual +-- exclusion. That is provided by the lock +-- System.Tasking.Task_Attributes.All_Attrs_L. + +-- One special problem that added complexity to the design is that +-- the per-task list of indirect attributes contains objects of +-- different types. We use unchecked pointer conversion to link +-- these nodes together and access them, but the records may not have +-- identical internal structure. Initially, we thought it would be +-- enough to allocate all the common components of the records at the +-- front of each record, so that their positions would correspond. +-- Unfortunately, GNAT adds "dope" information at the front of a record, +-- if the record contains any controlled-type components. +-- +-- This means that the offset of the fields we use to link the nodes is +-- at different positions on nodes of different types. To get around this, +-- each attribute storage record consists of a core node and wrapper. +-- The core nodes are all of the same type, and it is these that are +-- linked together and generally "seen" by the RTS. Each core node +-- contains a pointer to its own wrapper, which is a record that contains +-- the core node along with an attribute value, approximately +-- as follows: + +-- type Node; +-- type Node_Access is access all Node; +-- type Node_Access; +-- type Access_Wrapper is access all Wrapper; +-- type Node is record +-- Next : Node_Access; +-- ... +-- Wrapper : Access_Wrapper; +-- end record; +-- type Wrapper is record +-- Noed : aliased Node; +-- Value : aliased Attribute; -- the generic formal type +-- end record; + +-- Another interesting problem is with the initialization of +-- the instantiation descriptors. Originally, we did this all via +-- the Initialize procedure of the descriptor type and code in the +-- package body. It turned out that the Initialize procedure needed +-- quite a bit of information, including the size of the attribute +-- type, the initial value of the attribute (if it fits in the TCB), +-- and a pointer to the deallocator procedure.

Syntactic and semantic information is combined in +-- this tree. There is no separate symbol table structure. + +-- WARNING: There is a C version of this package. Any changes to this +-- source file must be properly reflected in the C header file tree.h + +-- Package Atree defines the basic structure of the tree and its nodes and +-- provides the basic abstract interface for manipulating the tree. Two +-- other packages use this interface to define the representation of Ada +-- programs using this tree format. The package Sinfo defines the basic +-- representation of the syntactic structure of the program, as output +-- by the parser. The package Entity_Info defines the semantic information +-- which is added to the tree nodes that represent declared entities (i.e. +-- the information which might typically be described in a separate symbol +-- table structure. + +-- The front end of the compiler first parses the program and generates a +-- tree that is simply a syntactic representation of the program in abstract +-- syntax tree format. Subsequent processing in the front end traverses the +-- tree, transforming it in various ways and adding semantic information. + + ---------------------------------------- + -- Definitions of Fields in Tree Node -- + ---------------------------------------- + + -- The representation of the tree is completely hidden, using a functional + -- interface for accessing and modifying the contents of nodes. Logically + -- a node contains a number of fields, much as though the nodes were + -- defined as a record type. The fields in a node are as follows: + + -- Nkind Indicates the kind of the node. This field is present + -- in all nodes. The type is Node_Kind, which is declared + -- in the package Sinfo. + + -- Sloc Location (Source_Ptr) of the corresponding token + -- in the Source buffer. The individual node definitions + -- show which token is referenced by this pointer. + + -- In_List A flag used to indicate if the node is a member + -- of a node list. + + -- Rewrite_Sub A flag set if the node has been rewritten using + -- the Rewrite procedure. The original value of the + -- node is retrievable with Original_Node. + + -- Rewrite_Ins A flag set if a node is marked as a rewrite inserted + -- node as a result of a call to Mark_Rewrite_Insertion. + + -- Paren_Count A 2-bit count used on expression nodes to indicate + -- the level of parentheses. Up to 3 levels can be + -- accomodated. Anything more than 3 levels is treated + -- as 3 levels (conformance tests that complain about + -- this are hereby deemed pathological!) Set to zero + -- for non-subexpression nodes. + + -- Comes_From_Source + -- This flag is present in all nodes. It is set if the + -- node is built by the scanner or parser, and clear if + -- the node is built by the analyzer or expander. It + -- indicates that the node corresponds to a construct + -- that appears in the original source program. + + -- Analyzed This flag is present in all nodes. It is set when + -- a node is analyzed, and is used to avoid analyzing + -- the same node twice. Analysis includes expansion if + -- expansion is active, so in this case if the flag is + -- set it means the node has been analyzed and expanded. + + -- Error_Posted This flag is present in all nodes. It is set when + -- an error message is posted which is associated with + -- the flagged node. This is used to avoid posting more + -- than one message on the same node. + + -- Field1 + -- Field2 + -- Field3 + -- Field4 + -- Field5 Five fields holding Union_Id values + + -- Char_CodeN Synonym for FieldN typed as Char_Code + -- ElistN Synonym for FieldN typed as Elist_Id + -- ListN Synonym for FieldN typed as List_Id + -- NameN Synonym for FieldN typed as Name_Id + -- NodeN Synonym for FieldN typed as Node_Id + -- StrN Synonym for FieldN typed as String_Id + -- UintN Synonym for FieldN typed as Uint (Empty = Uint_0) + -- UrealN Synonym for FieldN typed as Ureal + + -- Note: the actual usage of FieldN (i.e. whether it contains a Char_Code, + -- Elist_Id, List_Id, Name_Id, Node_Id, String_Id, Uint or Ureal), depends + -- on the value in Nkind. Generally the access to this field is always via + -- the functional interface, so the field names Char_CodeN, ElistN, ListN, + -- NameN, NodeN, StrN, UintN and UrealN are used only in the bodies of the + -- access functions (i.e. in the bodies of Sinfo and Einfo). These access + -- functions contain debugging code that checks that the use is consistent + -- with Nkind and Ekind values. + + -- However, in specialized circumstances (examples are the circuit in + -- generic instantiation to copy trees, and in the tree dump routine), + -- it is useful to be able to do untyped traversals, and an internal + -- package in Atree allows for direct untyped accesses in such cases. + + -- Flag4 Fifteen Boolean flags (use depends on Nkind and + -- Flag5 Ekind, as described for Fieldn). Again the access + -- Flag6 is usually via subprograms in Sinfo and Einfo which + -- Flag7 provide high-level synonyms for these flags, and + -- Flag8 contain debugging code that checks that the values + -- Flag9 in Nkind and Ekind are appropriate for the access. + -- Flag10 + -- Flag11 Note that Flag1-3 are missing from this list. The + -- Flag12 first three flag positions are reserved for the + -- Flag13 standard flags (Comes_From_Source, Error_Posted, + -- Flag14 and Analyzed) + -- Flag15 + -- Flag16 + -- Flag17 + -- Flag18 + + -- Link For a node, points to the Parent.

This field is + -- private to the Atree package (but is also modified + -- by the Nlists package). + + -- The following additional fields are present in extended nodes used + -- for entities (Nkind in N_Entity). + + -- Ekind Entity type.

This count is incremented every time a node or entity is + -- allocated, and decremented every time a node or entity is deleted. + -- This value is used by Xref and by Treepr to allocate hash tables of + -- suitable size for hashing Node_Id values. + + ----------------------- + -- Use of Empty Node -- + ----------------------- + + -- The special Node_Id Empty is used to mark missing fields. Whenever the + -- syntax has an optional component, then the corresponding field will be + -- set to Empty if the component is missing. + + -- Note: Empty is not used to describe an empty list. Instead in this + -- case the node field contains a list which is empty, and these cases + -- should be distinguished (essentially from a type point of view, Empty + -- is a Node, and is thus not a list). + + -- Note: Empty does in fact correspond to an allocated node. Only the + -- Nkind field of this node may be referenced. It contains N_Empty, which + -- uniquely identifies the empty case. This allows the Nkind field to be + -- dereferenced before the check for Empty which is sometimes useful. + + ----------------------- + -- Use of Error Node -- + ----------------------- + + -- The Error node is used during syntactic and semantic analysis to + -- indicate that the corresponding piece of syntactic structure or + -- semantic meaning cannot properly be represented in the tree because + -- of an illegality in the program. + + -- If an Error node is encountered, then you know that a previous + -- illegality has been detected. The proper reaction should be to + -- avoid posting related cascaded error messages, and to propagate + -- the error node if necessary. + + ----------------------- + -- Current_Error_Node -- + ----------------------- + + -- The current error node is a global location indicating the current + -- node that is being processed for the purposes of placing a compiler + -- abort message. This is not necessarily perfectly accurate, it is + -- just a reasonably accurate best guess. It is used to output the + -- source location in the abort message by Comperr, and also to + -- implement the d3 debugging flag. This is also used by Rtsfind + -- to generate error messages for No_Run_Time mode. + + Current_Error_Node : Node_Id; + -- Node to place error messages + + ------------------------------- + -- Default Setting of Fields -- + ------------------------------- + + -- Nkind is set to N_Unused_At_Start + + -- Ekind is set to E_Void + + -- Sloc is always set, there is no default value + + -- Field1-5 fields are set to Empty + + -- Field6-22 fields in extended nodes are set to Empty + + -- Parent is set to Empty + + -- All Boolean flag fields are set to False + + -- Note: the value Empty is used in Field1-Field17 to indicate a null node. + -- The usage varies. The common uses are to indicate absence of an + -- optional clause or a completely unused Field1-17 field. + + ------------------------------------- + -- Use of Synonyms for Node Fields -- + ------------------------------------- + + -- A subpackage Atree.Unchecked_Access provides routines for reading and + -- writing the fields defined above (Field1-17, Node1-17, Flag1-88 etc). + -- These unchecked access routines can be used for untyped traversals. In + -- In addition they are used in the implementations of the Sinfo and + -- Einfo packages. These packages both provide logical synonyms for + -- the generic fields, together with an appropriate set of access routines. + -- Normally access to information within tree nodes uses these synonyms, + -- providing a high level typed interface to the tree information. + + -------------------------------------------------- + -- Node Allocation and Modification Subprograms -- + -------------------------------------------------- + + -- Generally the parser builds the tree and then it is further decorated + -- (e.g. by setting the entity fields), but not fundamentally modified. + -- However, there are cases in which the tree must be restructured by + -- adding and rearranging nodes, as a result of disambiguating cases + -- which the parser could not parse correctly, and adding additional + -- semantic information (e.g. making constraint checks explicit).
