71 The TRE regular expression implementation (src/regex/reg* and
72 src/regex/tre*) is Copyright © 2001-2008 Ville Laurikari and licensed
73 under a 2-clause BSD license (license text in the source files). The
74 included version has been heavily modified by Rich Felker in 2012, in
75 the interests of size, simplicity, and namespace cleanliness.
77 Much of the math library code (src/math/* and src/complex/*) is
78 Copyright © 1993,2004 Sun Microsystems or

82 Copyright © 2008 Stephen L. Moshier
83 and labelled as such in comments in the individual source files. All
84 have been licensed under extremely permissive terms.
86 The ARM memcpy code (src/string/armel/memcpy.s) is Copyright © 2008
87 The Android Open Source Project and is licensed under a two-clause BSD
88 license. It was taken from Bionic libc, used on Android.
90 The implementation of DES for crypt (src/misc/crypt_des.c) is
91 Copyright © 1994 David Burren. It is licensed under a BSD license.
93 The implementation of blowfish crypt (src/misc/crypt_blowfish.c) was
94 originally written by Solar Designer and placed into the public
95 domain. The code also comes with a fallback permissive license for use
96 in jurisdictions that may not recognize the public domain.
98 The smoothsort implementation (src/stdlib/qsort.c) is Copyright © 2011
99 Valentin Ochs and is licensed under an MIT-style license.
101 The BSD PRNG implementation (src/prng/random.c) and XSI search API
102 (src/search/*.c) functions are Copyright © 2011 Szabolcs Nagy and
103 licensed under following terms: "Permission to use, copy, modify,
104 and/or distribute this code for any purpose with or without fee is
105 hereby granted. There is no warranty."
107 The x86_64 port was written by Nicholas J. Kain. Several files (crt)
108 were released into the public domain; others are licensed under the
109 standard MIT license terms at the top of this file. See individual
110 files for their copyright status.
112 The mips and microblaze ports were originally written by Richard
113 Pennington for use in the ellcc project. The original code was adapted
114 by Rich Felker for build system and code conventions during upstream
115 integration. It is licensed under the standard MIT terms.
117 The powerpc port was also originally written by Richard Pennington,
118 and later supplemented and integrated by John Spencer. It is licensed
119 under the standard MIT terms.
121 All other files which have no copyright comments are original works
122 produced specifically for use as part of this library, written either
123 by Rich Felker, the main author of the library, or by one or more
124 contibutors listed above. Details on authorship of individual files
125 can be found in the git version control history of the project. The
126 omission of copyright and license comments in each file is in the
127 interest of source tree size.
129 All public header files (include/* and arch/*/bits/*) should be
130 treated as Public Domain as they intentionally contain no content
131 which can be covered by copyright. Some source modules may fall in
132 this category as well. If you believe that a file is so trivial that
133 it should be in the Public Domain, please contact the authors and
134 request an explicit statement releasing it from copyright.
136 The following files are trivial, believed not to be copyrightable in
137 the first place, and hereby explicitly released to the Public Domain:
