GPL v3 GCC Runtime Library Exception
17 Dell EMC PowerStore: Open Source License and Copyright Information for GPLv3/LGPLv3
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.
