src/regex/tre*) is Copyright © 2001-2008 Ville Laurikari and licensed
|
||||
under a 2-clause BSD license (license text in the source files). The
|
||||
included version has been heavily modified by Rich Felker in 2012, in
|
||||
the interests of size, simplicity, and namespace cleanliness.
|
||||
|
||||
Much of the math library code (src/math/ * and src/complex/ *) is
|
||||
Copyright © 1993,2004 Sun Microsystems or
|
||||
Copyright © 2003-2011 David Schultz or

Copyright © 2003-2009 Bruce D. Evans or

|

and labelled as such in comments in the individual source files. All
|
||||
have been licensed under extremely permissive terms.
|
||||
|
||||
The ARM memcpy code (src/string/arm/memcpy_el.S) is Copyright © 2008
|
||||
The Android Open Source Project and is licensed under a two-clause BSD
|
||||
license. It was taken from Bionic libc, used on Android.
|
||||
|
||||
The implementation of DES for crypt (src/crypt/crypt_des.c) is
|
||||
Copyright © 1994 David Burren. It is licensed under a BSD license.
|
||||
|
||||
The implementation of blowfish crypt (src/crypt/crypt_blowfish.c) was
|
||||
originally written by Solar Designer and placed into the public
|
||||
domain. The code also comes with a fallback permissive license for use
|
||||
in jurisdictions that may not recognize the public domain.
|
||||
|
||||
The smoothsort implementation (src/stdlib/qsort.c) is Copyright © 2011
|
||||
Valentin Ochs and is licensed under an MIT-style license.
|
||||
|
||||
The BSD PRNG implementation (src/prng/random.c) and XSI search API
|
||||
(src/search/ *.c) functions are Copyright © 2011 Szabolcs Nagy and
|
||||
licensed under following terms: "Permission to use, copy, modify,
|
||||
and/or distribute this code for any purpose with or without fee is
|
||||
hereby granted. There is no warranty."
|
||||
|
||||
The x86_64 port was written by Nicholas J. Kain and is licensed under
|
||||
the standard MIT terms.
|
||||
|
||||
The mips and microblaze ports were originally written by Richard
|
||||
Pennington for use in the ellcc project. The original code was adapted
|
||||
by Rich Felker for build system and code conventions during upstream
|
||||
integration. It is licensed under the standard MIT terms.
|
||||
|
||||
The mips64 port was contributed by Imagination Technologies and is
|
||||
licensed under the standard MIT terms.
|
||||
|
||||
The powerpc port was also originally written by Richard Pennington,
|
||||
and later supplemented and integrated by John Spencer. It is licensed
|
||||
under the standard MIT terms.
|
||||
|
||||
All other files which have no copyright comments are original works
|
||||
produced specifically for use as part of this library, written either
|
||||
by Rich Felker, the main author of the library, or by one or more
|
||||
contibutors listed above. Details on authorship of individual files
|
||||
can be found in the git version control history of the project. The
|
||||
omission of copyright and license comments in each file is in the
|
||||
interest of source tree size.
|
||||
|
||||
In addition, permission is hereby granted for all public header files
|
||||
(include/ * and arch/ * /bits/ *) and crt files intended to be linked into
|
||||
applications (crt/ *, ldso/dlstart.c, and arch/ * /crt_arch.h) to omit
|
||||
the copyright notice and permission notice otherwise required by the
|
||||
license, and to use these files without any requirement of
|
||||
attribution. These files include substantial contributions from:
|
||||
|
||||
Bobby Bingham
|
||||
John Spencer
|
||||
Nicholas J. Kain
|
||||
Rich Felker
|
||||
Richard Pennington
|
||||
Stefan Kristiansson
|
||||
Szabolcs Nagy
|
||||
|
||||
all of whom have explicitly granted such permission.
|
||||
|
||||
This file previously contained text expressing a belief that most of
|
||||
the files covered by the above exception were sufficiently trivial not
|
||||
to be subject to copyright, resulting in confusion over whether it
|
||||
negated the permissions granted in the license. In the spirit of
|
||||
permissive licensing, and of not having licensing issues being an
|
||||
obstacle to adoption, that text has been removed.
