These --- are values that are referenced by the runtime library and are therefore --- relevant to the target machine. - --- The parameters whose value is defined in the spec are not generally --- expected to be changed. If they are changed, it will be necessary to --- recompile the run-time library. - --- The parameters which are defined by functions can be changed by modifying --- the body of System.Parameters in file s-parame.adb. A change to this body --- requires only rebinding and relinking of the application. - --- Note: do not introduce any pragma Inline statements into this unit, since --- otherwise the relinking and rebinding capability would be deactivated. - -package System.Parameters is - pragma Pure; - - --------------------------------------- - -- Task And Stack Allocation Control -- - --------------------------------------- - - type Task_Storage_Size is new Integer; - -- Type used in tasking units for task storage size - - type Size_Type is new Task_Storage_Size; - -- Type used to provide task storage size to runtime - - Unspecified_Size : constant Size_Type := Size_Type'First; - -- Value used to indicate that no size type is set - - subtype Ratio is Size_Type range -1 .. 100; - Dynamic : constant Size_Type := -1; - -- The secondary stack ratio is a constant between 0 and 100 which - -- determines the percentage of the allocated task stack that is - -- used by the secondary stack (the rest being the primary stack). - -- The special value of minus one indicates that the secondary - -- stack is to be allocated from the heap instead. - - Sec_Stack_Ratio : constant Ratio := Dynamic; - -- This constant defines the handling of the secondary stack - - Sec_Stack_Dynamic : constant Boolean := Sec_Stack_Ratio = Dynamic; - -- Convenient Boolean for testing for dynamic secondary stack - - function Default_Stack_Size return Size_Type; - -- Default task stack size used if none is specified - - function Minimum_Stack_Size return Size_Type; - -- Minimum task stack size permitted - - function Adjust_Storage_Size (Size : Size_Type) return Size_Type; - -- Given the storage size stored in the TCB, return the Storage_Size - -- value required by the RM for the Storage_Size attribute.

It is used for - -- proper implementation of the stack overflow check. - - ---------------------------------------------- - -- Characteristics of types in Interfaces.C -- - ---------------------------------------------- - - long_bits : constant := 32; - -- Number of bits in type long and unsigned_long. The normal convention - -- is that this is the same as type Long_Integer, but this is not true - -- of all targets. For example, in OpenVMS long /= Long_Integer. - - ---------------------------------------------- - -- Behavior of Pragma Finalize_Storage_Only -- - ---------------------------------------------- - - -- Garbage_Collected is a Boolean constant whose value indicates the - -- effect of the pragma Finalize_Storage_Entry on a controlled type. - - -- Garbage_Collected = False - - -- The system releases all storage on program termination only, - -- but not other garbage collection occurs, so finalization calls - -- are ommitted only for outer level onjects can be omitted if - -- pragma Finalize_Storage_Only is used. - - -- Garbage_Collected = True - - -- The system provides full garbage collection, so it is never - -- necessary to release storage for controlled objects for which - -- a pragma Finalize_Storage_Only is used. - - Garbage_Collected : constant Boolean := False; - -- The storage mode for this system (release on program exit) - - --------------------- - -- Tasking Profile -- - --------------------- - - -- In the following sections, constant parameters are defined to - -- allow some optimizations and fine tuning within the tasking run time - -- based on restrictions on the tasking features. - - ---------------------- - -- Locking Strategy -- - ---------------------- - - Single_Lock : constant Boolean := False; - -- Indicates whether a single lock should be used within the tasking - -- run-time to protect internal structures. If True, a single lock - -- will be used, meaning less locking/unlocking operations, but also - -- more global contention. In general, Single_Lock should be set to - -- True on single processor machines, and to False to multi-processor - -- systems, but this can vary from application to application and also - -- depends on the scheduling policy. - - ------------------- - -- Task Abortion -- - ------------------- - - No_Abort : constant Boolean := False; - -- This constant indicates whether abort statements and asynchronous - -- transfer of control (ATC) are disallowed. If set to True, it is - -- assumed that neither construct is used, and the run time does not - -- need to defer/undefer abort and check for pending actions at - -- completion points. A value of True for No_Abort corresponds to: - -- pragma Restrictions (No_Abort_Statements); - -- pragma Restrictions (Max_Asynchronous_Select_Nesting => 0); - - ---------------------- - -- Dynamic Priority -- - ---------------------- - - Dynamic_Priority_Support : constant Boolean := True; - -- This constant indicates whether dynamic changes of task priorities - -- are allowed (True means normal RM mode in which such changes are - -- allowed). In particular, if this is False, then we do not need to - -- poll for pending base priority changes at every abort completion - -- point.
