GCC RUNTIME LIBRARY EXCEPTION
|
|
|
|
Version 3.1, 31 March 2009
|
|
|
|
Copyright (C) 2009 Free Software Foundation, Inc. <http://fsf.org/>
|
|
|
|
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.
|
|
|
|
0. 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.
|
|
|
|
1. 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.
|
|
|
|
2. 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.
