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 three possible forms -- depending on Gnatvsn.Gnat_Version_Type (FSF, Public, GNATPRO). -- See body of this package for the exact text used. -- In addition, 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 remaining text. 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. end Comperr;
