Everyone is permitted to copy and distribute verbatim copies of
         this license document, but changing it is not allowed.
      
This GCC Runtime Library Exception ("Exception") is an
           additional permission under section 7 of the GNU
           General Public License, version 3 ("GPLv3"). It
           applies to a given file (the "Runtime Library") that
           bears a notice placed by the copyright holder of the
           file stating that the file is governed by GPLv3 along
           with this Exception.

      
When you use GCC to compile a program, GCC may combine portions
         of certain GCC header files and runtime libraries with the
         compiled program. The purpose of this Exception is to allow
         compilation of non-GPL (including proprietary) programs to
         use, in this way, the header files and runtime libraries
         covered by this Exception.

      ]^$
          Definitions.
          
A file is an "Independent Module" if it either requires
             the Runtime Library for execution after a Compilation
             Process, or makes use of an interface provided by the
             Runtime Library, but is not otherwise based on the
             Runtime Library.

            
"GCC" means a version of the GNU Compiler Collection,
             with or without modifications, governed by version 3
             (or a specified later version) of the GNU General
             Public License (GPL) with the option of using any
             subsequent versions published by the FSF.

            
"GPL-compatible Software" is software whose conditions of
             propagation, modification and use would permit
             combination with GCC in accord with the license of
             GCC.

            
"Target Code" refers to output from any compiler for a
             real or virtual target processor architecture, in
             executable form or suitable for input to an assembler,
             loader, linker and/or execution phase. Notwithstanding
             that, Target Code does not include data in any format
             that is used as a compiler intermediate
             representation, or used for producing a compiler
             intermediate representation.

            
The "Compilation Process" transforms code entirely
             represented in non-intermediate languages designed for
             human-written code, and/or in Java Virtual Machine
             byte code, into Target Code. Thus, for example, use of
             source code generators and preprocessors need not be
             considered part of the Compilation Process, since the
             Compilation Process can be understood as starting with
             the output of the generators or preprocessors.

            
A Compilation Process is "Eligible" if it is done using
             GCC, alone or with other GPL-compatible software, or
             if it is done without using any work based on GCC. For
             example, using non-GPL-compatible Software to optimize
             any GCC intermediate representations would not qualify
             as an Eligible Compilation Process.

          Grant of Additional Permission.
          
You have permission to propagate a work of Target Code
             formed by combining the Runtime Library with
             Independent Modules, even if such propagation would
             otherwise violate the terms of GPLv3, provided that
             all Target Code was generated by Eligible Compilation
             Processes. You may then convey such a combination
             under terms of your choice, consistent with the
             licensing of the Independent Modules.

          No Weakening of GCC Copyleft.
      
The availability of this Exception does not imply any general
         presumption that third-party software is unaffected by the
         copyleft requirements of the license of GCC.
