-- This version of Ada.Exceptions is a full Ada 95 version, and Ada 2005
-- features such as the additional definitions of Exception_Name returning
-- Wide_[Wide_]String.
-- It is used for building the compiler and the basic tools, since these
-- builds may be done with bootstrap compilers that cannot handle these
-- additions. The full version of Ada.Exceptions can be found in the files
-- a-except-2005.ads/adb, and is used for all other builds where full Ada
-- 2005 functionality is required. In particular, it is used for building
-- run times on all targets.

-- This routine is called to setup the exception referenced by the

-- and message. Msg1 is a null terminated string which is generated
-- as the exception message. If line is non-zero, then a colon and
-- the decimal representation of this integer is appended to the
-- message. Ditto for Column. When Msg2 is non-null, a space and this
-- additional null terminated string is added to the message.
procedure Set_Exception_Msg
(Excep : EOA;
Id : Exception_Id;
Message : String);
-- This routine is called to setup the exception referenced by the
-- Current_Excep field in the TSD to contain the indicated Id value and
-- message. Message is a string which is generated as the exception
-- message.
--------------------------------------
-- Exception information subprogram --
--------------------------------------
function Exception_Information (X : Exception_Occurrence) return String;
-- The format of the exception information is as follows:
--
-- Exception_Name: <exception name> (as in Exception_Name)
-- Message: <message> (only if Exception_Message is empty)
-- PID=nnnn (only if != 0)
-- Call stack traceback locations: (only if at least one location)
-- <0xyyyyyyyy 0xyyyyyyyy ...> (is recorded)
--
-- The lines are separated by a ASCII.LF character
--
-- The nnnn is the partition Id given as decimal digits
--
-- The 0x... line represents traceback program counter locations, in
-- execution order with the first one being the exception location. It
-- is present only
--
-- The Exception_Name and Message lines are omitted in the abort signal
-- case, since this is not really an exception.
-- Note: If the format of the generated string is changed, please note
-- that an equivalent modification to the routine String_To_EO must be
-- made to preserve proper functioning of the stream attributes.
---------------------------------------
-- Exception backtracing subprograms --
---------------------------------------
-- What is automatically output when exception tracing is on is the
-- usual exception information with the call chain backtrace possibly
-- tailored by a backtrace decorator. Modifying Exception_Information
-- itself is not a good idea because the decorated output is completely
-- out of control and would break all our code related to the streaming
-- of exceptions. We then provide an alternative function to compute
-- the possibly tailored output, which is equivalent if no decorator is
-- currently set:
function Tailored_Exception_Information
(X : Exception_Occurrence) return String;
-- Exception information to be output in the case of automatic tracing
-- requested through GNAT.Exception_Traces.
--
-- This is the same as Exception_Information if no backtrace decorator
-- is currently in place. Otherwise, this is Exception_Information with
-- the call chain raw addresses replaced by the result of a call to the
-- current decorator provided with the call chain addresses.
