|
|
-- This package obtains parameters from the target runtime version of System,
|
|
-- to indicate parameters relevant to the target environment.
|
|
|
|
-- Conceptually, these parameters could be obtained using rtsfind, but
|
|
-- we do not do this for four reasons:
|
|
|
|
-- 1. Compiling System for every compilation wastes time
|
|
|
|
-- 2. This compilation impedes debugging by adding extra compile steps
|
|
|
|
-- 3. There are recursion problems coming from compiling System itself
|
|
-- or any of its children.
|
|
|
|
-- 4. The binder also needs the parameters, and we do not want to have
|
|
-- to drag a lot of front end stuff into the binder.
|
|
|
|
-- For all these reasons, we read in the source of System, and then scan
|
|
-- it at the text level to extract the parameter values.
|
|
|
|
-- Note however, that later on, when the ali file is written, we make sure
|
|
-- that the System file is at least parsed, so that the checksum is properly
|
|
-- computed and set in the ali file. This partially negates points 1 and 2
|
|
-- above although just parsing is quick and does not impact debugging much.
|
|
|
|
-- The parameters acquired by this routine from system.ads fall into four
|
|
-- categories:
|
|
|
|
-- 1. Configuration pragmas, that must appear at the start of the file.
|
|
-- Any such pragmas automatically apply to any unit compiled in the
|
|
-- presence of this system file. Only a limited set of such pragmas
|
|
-- may appear as documented in the corresponding section below.
|
|
|
|
-- 2. Target parameters. These are boolean constants that are defined
|
|
-- in the private part of the package giving fixed information
|
|
-- about the target architecture, and the capabilities of the
|
|
-- code generator and run-time library.
|
|
|
|
-- 3. Identification information. This is an optional string constant
|
|
-- that gives the name of the run-time library configuration. This
|
|
-- line may be omitted for a version of system.ads to be used with
|
|
-- the full Ada 95 run time.
|
|
|
|
-- 4. Other characteristics of package System. At the current time the
|
|
-- only item in this category is whether type Address is private.

-- Target Parameters --

-----------------------
|
|
|
|
-- The following parameters correspond to the variables defined in the

|
|
-- that it is required that all parameters defined here be specified

|
-- parameter, add it to all system*.ads files. (There is a defaulting
|
|
-- mechanism, but we don't normally take advantage of it, as explained
|
|
-- below.)
|
|
|
|
-- The default values here are used if no value is found in system.ads.
|
|
-- This should normally happen if the special version of system.ads used
|
|
-- by the compiler itself is in use or if the value is only relevant to a
|
|
-- particular target. The default values are suitable for use in normal
|
|
-- environments. This approach allows the possibility of new versions of
|
|
-- the compiler (possibly with new system parameters added) being used to
|
|
-- compile older versions of the compiler sources, as well as avoiding
|
|
-- duplicating values in all system-*.ads files for flags that are used on
|
|
-- a few platforms only.
|
|
|
|
-- All these parameters should be regarded as read only by all clients

-----------------------------------
|
|
-- Control of Exception Handling --
|
|
-----------------------------------
|
|
|
|
-- GNAT implements three methods of implementing exceptions:
|
|
|
|
-- Front-End Longjmp/Setjmp Exceptions
|
|
|
|
-- This approach uses longjmp/setjmp to handle exceptions. It
|
|
-- uses less storage, and can often propagate exceptions faster,
|
|
-- at the expense of (sometimes considerable) overhead in setting
|
|
-- up an exception handler.
|
|
|
|
-- The generation of the setjmp and longjmp calls is handled by
|
|
-- the front end of the compiler (this includes gigi in the case
|
|
-- of the standard GCC back end). It does not use any back end
|
|
-- support (such as the GCC3 exception handling mechanism). When
|
|
-- this approach is used, the compiler generates special exception
|
|
-- handlers for handling cleanups (AT-END actions) when an exception
|
|
-- is raised.
|
|
|
|
-- Back-End Zero Cost Exceptions
|
|
|
|
-- With this approach, the back end handles the generation and
|
|
-- handling of exceptions. For example, the GCC3 exception handling
|
|
-- mechanisms are used in this mode. The front end simply generates
|
|
-- code for explicit exception handlers, and AT-END cleanup handlers
|
|
-- are simply passed unchanged to the backend for generating cleanups
|
|
-- both in the exceptional and non-exceptional cases.
|
|
|
|
-- As the name implies, this approach uses a table-based mechanism,
|
|
-- which incurs no setup when entering a region covered by handlers
|
|
-- but requires complex unwinding to walk up the call chain and search
|
|
-- for handlers at propagation time.
|
|
|
|
-- Back-End Setjmp/Longjmp Exceptions
|
|
|
|
-- With this approach, the back end also handles the generation and
|
|
-- handling of exceptions, using setjmp/longjmp to set up receivers and
|
|
-- propagate. AT-END actions on exceptional paths are also taken care
|
|
-- of by the back end and the front end doesn't need to generate
|
|
-- explicit exception handlers for these.
|
|
|
|
-- Control of Available Methods and Defaults
|
|
|
|
-- The following switches specify whether we're using a front-end or a
|
|
-- back-end mechanism and whether this is a zero-cost or a sjlj scheme.
|
|
|
|
-- The per-switch default values correspond to the default value of
|
|
-- Opt.Exception_Mechanism.

-- Indicates if zero cost scheme for exceptions

|
-- Run-Time Library Configuration --
|
|
------------------------------------
|
|
|
|
-- In configurable run-time mode, the system run-time may not support
|
|
-- the full Ada language. The effect of setting this switch is to let
|
|
-- the compiler know that it is not surprising (i.e. the system is not
|
|
-- misconfigured) if run-time library units or entities within units are
|
|
-- not present in the run-time.
|
|
|
|
Configurable_Run_Time_On_Target : Boolean := False;
|
|
-- Indicates that the system.ads file is for a configurable run-time
|
|
--
|
|
-- This has some specific effects as follows
|
|
--
|
|
-- The binder generates the gnat_argc/argv/envp variables in the
|
|
-- binder file instead of being imported from the run-time library.
|
|
-- If Command_Line_Args_On_Target is set to False, then the
|
|
-- generation of these variables is suppressed completely.
|
|
--
|
|
-- The binder generates the gnat_exit_status variable in the binder
|
|
-- file instead of being imported from the run-time library. If
|
|
-- Exit_Status_Supported_On_Target is set to False, then the
|
|
-- generation of this variable is suppressed entirely.
|
|
--
|
|
-- The routine __gnat_break_start is defined within the binder file
|
|
-- instead of being imported from the run-time library.
|
|
--
|
|
-- The variable __gnat_exit_status is generated within the binder file
|
|
-- instead of being imported from the run-time library.
|
|
|
|
Suppress_Standard_Library_On_Target : Boolean := False;

|
-- If this flag is True, then the standard library is not included by

-- s-stalib.ads for details of what this includes). This is for example
|
|
-- set True for the zero foot print case, where these files should not
|
|
-- be included by default.
|
|
--
|
|
-- This flag has some other related effects:
|
|
--
|
|
-- The generation of global variables in the bind file is suppressed,
|
|
-- with the exception of the priority of the environment task, which
|
|
-- is needed by the Ravenscar run-time.

|
Preallocated_Stacks_On_Target : Boolean := False;
|
|
-- If this flag is True, then the expander preallocates all task stacks

|
|
-- Duration Format --
|
|
---------------------
|
|
|
|
-- By default, type Duration is a 64-bit fixed-point type with a delta
|
|
-- and small of 10**(-9) (i.e. it is a count in nanoseconds). This flag

|
-- These flags indicate possible limitations in what the code generator

|
-- of these may be false for a configurable run-time, and if a feature is
|
|
-- used at the source level, and the corresponding flag is false, then an

-- on a multi-processor to synchronize tasks (e.g. by using spin locks).
|
|
-- The setting of this flag determines the default behavior. Normally this

|
-- Control of Stack Checking --
|
|
-------------------------------
|
|
|
|
-- GNAT provides three methods of implementing exceptions:
|
|
|
|
-- GCC Probing Mechanism
|
|
|
|
-- This approach uses the standard GCC mechanism for
|
|
-- stack checking. The method assumes that accessing
|
|
-- storage immediately beyond the end of the stack
|
|
-- will result in a trap that is converted to a storage
|
|
-- error by the runtime system. This mechanism has
|
|
-- minimal overhead, but requires complex hardware,
|
|
-- operating system and run-time support. Probing is
|
|
-- the default method where it is available. The stack
|
|
-- size for the environment task depends on the operating
|
|
-- system and cannot be set in a system-independent way.
|
|
|
|
-- GCC Stack-limit Mechanism
|
|
|
|
-- This approach uses the GCC stack limits mechanism.
|
|
-- It relies on comparing the stack pointer with the
|
|
-- values of a global symbol. If the check fails, a
|
|
-- trap is explicitly generated. The advantage is
|
|
-- that the mechanism requires no memory protection,
|
|
-- but operating system and run-time support are
|
|
-- needed to manage the per-task values of the symbol.
|
|
-- This is the default method after probing where it
|
|
-- is available.
|
|
|
|
-- GNAT Stack-limit Checking
|
|
|
|
-- This method relies on comparing the stack pointer
|
|
-- with per-task stack limits. If the check fails, an
|
|
-- exception is explicitly raised. The advantage is
|
|
-- that the method requires no extra system dependent
|
|
-- runtime support and can be used on systems without
|
|
-- memory protection as well, but at the cost of more
|
|
-- overhead for doing the check. This is the fallback
|
|
-- method if the above two are not supported.

|
Stack_Check_Probes_On_Target : Boolean := False;

-- Indicates if the GCC probing mechanism is used
