|
-- This package contains the routine called when a fatal internal compiler
|
|
-- error is detected. Calls to this routines cause termination of the
|
|
-- current compilation with appropriate error output.
|
|
|
|
package Comperr is
|
|
|
|
procedure Compiler_Abort
|
|
(X : String;
|
|
Code : Integer := 0);
|
|
-- Signals an internal compiler error. Never returns control. Depending
|
|
-- on processing may end up raising Unrecoverable_Error, or exiting
|
|
-- directly. The message output is a "bug box" containing the
|
|
-- string passed as an argument. The node in Current_Error_Node is used
|
|
-- to provide the location where the error should be signalled. The
|
|
-- message includes the node id, and the code parameter if it is positive.
|
|
-- Note that this is only used at the outer level (to handle constraint
|
|
-- errors or assert errors etc.) In the normal logic of the compiler we
|
|
-- always use pragma Assert to check for errors, and if necessary an
|
|
-- explicit abort is achieved by pragma Assert (False). Code is positive
|
|
-- for a gigi abort (giving the gigi abort code), zero for a front
|
|
-- end exception (with possible message stored in TSD.Current_Excep,
|
|
-- and negative (an unused value) for a GCC abort.

-- Use of gnat_bug.box File --
|
|
------------------------------
|
|
|
|
-- When comperr generates the "bug box". The first two lines contain
|
|
-- information on the version number, type of abort, and source location.
|
|
|
|
-- Normally the remaining text is one of the following two forms
|
|
-- depending on the version number (p identifies public versions):
|
|
|
|
-- Please submit bug report by email to report@gnat.com.
|
|
-- Use a subject line meaningful to you and us to track the bug.
|
|
-- (include your customer number #nnn in the subject line).
|
|
-- Include the entire contents of this bug box in the report.
|
|
-- Include the exact gcc or gnatmake command that you entered.
|
|
-- Also include sources listed below in gnatchop format
|
|
-- (concatenated together with no headers between files).
|
|
-- (use plain ASCII or MIME attachment,
|
|
-- or FTP to your customer directory).
|
|
-- See README.GNATPRO for full info on procedure for submitting bugs.
|
|
|
|
-- or (public version case)
|
|
|
|
-- Please submit bug report by email to report@gnat.com.
|
|
-- Use a subject line meaningful to you and us to track the bug.
|
|
-- (include your customer number #nnn in the subject line).
|
|
-- Include the entire contents of this bug box in the report.
|
|
-- Include the exact gcc or gnatmake command that you entered.
|
|
-- Also include sources listed below in gnatchop format
|
|
-- (concatenated together with no headers between files).
|
|
-- See gnatinfo.txt for full info on procedure for submitting bugs.
|
|
|
|
-- However, an alternative mechanism exists for easily substituting
|
|
-- different text for this message. Compiler_Abort checks for the
|
|
-- existence of the file "gnat_bug.box" in the current source path.
|
|
-- Most typically this file, if present, will be in the directory
|
|
-- containing the run-time sources.
|
|
|
|
-- If this file is present, then it is a plain ASCII file, whose
|
|
-- contents replace the above quoted paragraphs. The lines in this
|
|
-- file should be 72 characters or less to avoid misformatting the
|
|
-- right boundary of the box. Note that the file does not contain
|
|
-- the vertical bar characters or any leading spaces in lines.
