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".

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; |
