     7  Everyone is permitted to copy and distribute verbatim copies of this
     8  license document, but changing it is not allowed.

    10  This GCC Runtime Library Exception ("Exception") is an additional
    11  permission under section 7 of the GNU General Public License, version
    12  3 ("GPLv3"). It applies to a given file (the "Runtime Library") that
    13  bears a notice placed by the copyright holder of the file stating that
    14  the file is governed by GPLv3 along with this Exception.
    15  
    16  When you use GCC to compile a program, GCC may combine portions of
    17  certain GCC header files and runtime libraries with the compiled
    18  program. The purpose of this Exception is to allow compilation of
    19  non-GPL (including proprietary) programs to use, in this way, the
    20  header files and runtime libraries covered by this Exception.
    21  
    22  0. Definitions.
    23  
    24  A file is an "Independent Module" if it either requires the Runtime
    25  Library for execution after a Compilation Process, or makes use of an
    26  interface provided by the Runtime Library, but is not otherwise based
    27  on the Runtime Library.
    28  
    29  "GCC" means a version of the GNU Compiler Collection, with or without
    30  modifications, governed by version 3 (or a specified later version) of
    31  the GNU General Public License (GPL) with the option of using any
    32  subsequent versions published by the FSF.
    33  
    34  "GPL-compatible Software" is software whose conditions of propagation,
    35  modification and use would permit combination with GCC in accord with
    36  the license of GCC.
    37  
    38  "Target Code" refers to output from any compiler for a real or virtual
    39  target processor architecture, in executable form or suitable for
    40  input to an assembler, loader, linker and/or execution
    41  phase. Notwithstanding that, Target Code does not include data in any
    42  format that is used as a compiler intermediate representation, or used
    43  for producing a compiler intermediate representation.
    44  
    45  The "Compilation Process" transforms code entirely represented in
    46  non-intermediate languages designed for human-written code, and/or in
    47  Java Virtual Machine byte code, into Target Code. Thus, for example,
    48  use of source code generators and preprocessors need not be considered
    49  part of the Compilation Process, since the Compilation Process can be
    50  understood as starting with the output of the generators or
    51  preprocessors.
    52  
    53  A Compilation Process is "Eligible" if it is done using GCC, alone or
    54  with other GPL-compatible software, or if it is done without using any
    55  work based on GCC. For example, using non-GPL-compatible Software to
    56  optimize any GCC intermediate representations would not qualify as an
    57  Eligible Compilation Process.
    58  
    59  1. Grant of Additional Permission.
    60  
    61  You have permission to propagate a work of Target Code formed by
    62  combining the Runtime Library with Independent Modules, even if such
    63  propagation would otherwise violate the terms of GPLv3, provided that
    64  all Target Code was generated by Eligible Compilation Processes. You
    65  may then convey such a combination under terms of your choice,
    66  consistent with the licensing of the Independent Modules.
    67  
    68  2. No Weakening of GCC Copyleft.
    69  
    70  The availability of this Exception does not imply any general
    71  presumption that third-party software is unaffected by the copyleft
    72  requirements of the license of GCC.
