-
--- 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 of the following form:
- -- Please submit bug a report, see http://gcc.gnu.org/bugs.html.
- -- 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.
-
- -- 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.
