111 Portions of this software are derived from third-party works licensed
112 under terms compatible with the above MIT license:
113
114 The TRE regular expression implementation (src/regex/reg* and
115 src/regex/tre*) is Copyright © 2001-2008 Ville Laurikari and licensed
116 under a 2-clause BSD license (license text in the source files). The
117 included version has been heavily modified by Rich Felker in 2012, in
118 the interests of size, simplicity, and namespace cleanliness.
119
120 Much of the math library code (src/math/* and src/complex/*) is
121 Copyright © 1993,2004 Sun Microsystems or
122 Copyright © 2003-2011 David Schultz or
123 Copyright © 2003-2009 Steven G. Kargl or
124 Copyright © 2003-2009 Bruce D. Evans or
125 Copyright © 2008 Stephen L. Moshier or
126 Copyright © 2017-2018 Arm Limited
127 and labelled as such in comments in the individual source files. All
128 have been licensed under extremely permissive terms.
129
130 The ARM memcpy code (src/string/arm/memcpy.S) is Copyright © 2008
131 The Android Open Source Project and is licensed under a two-clause BSD
132 license. It was taken from Bionic libc, used on Android.
133
134 The AArch64 memcpy and memset code (src/string/aarch64/*) are
135 Copyright © 1999-2019, Arm Limited.
136
137 The implementation of DES for crypt (src/crypt/crypt_des.c) is
138 Copyright © 1994 David Burren. It is licensed under a BSD license.
139
140 The implementation of blowfish crypt (src/crypt/crypt_blowfish.c) was
141 originally written by Solar Designer and placed into the public
142 domain. The code also comes with a fallback permissive license for use
143 in jurisdictions that may not recognize the public domain.
144
145 The smoothsort implementation (src/stdlib/qsort.c) is Copyright © 2011
146 Valentin Ochs and is licensed under an MIT-style license.
147
148 The x86_64 port was written by Nicholas J. Kain and is licensed under
149 the standard MIT terms.
150
151 The mips and microblaze ports were originally written by Richard
152 Pennington for use in the ellcc project. The original code was adapted
153 by Rich Felker for build system and code conventions during upstream
154 integration. It is licensed under the standard MIT terms.
155
156 The mips64 port was contributed by Imagination Technologies and is
157 licensed under the standard MIT terms.
158
159 The powerpc port was also originally written by Richard Pennington,
160 and later supplemented and integrated by John Spencer. It is licensed
161 under the standard MIT terms.
162
163 All other files which have no copyright comments are original works
164 produced specifically for use as part of this library, written either
165 by Rich Felker, the main author of the library, or by one or more
166 contibutors listed above. Details on authorship of individual files
167 can be found in the git version control history of the project. The
168 omission of copyright and license comments in each file is in the
169 interest of source tree size.
170
171 In addition, permission is hereby granted for all public header files
172 (include/* and arch/*/bits/*) and crt files intended to be linked into
173 applications (crt/*, ldso/dlstart.c, and arch/*/crt_arch.h) to omit
174 the copyright notice and permission notice otherwise required by the
175 license, and to use these files without any requirement of
176 attribution. These files include substantial contributions from:
177
178 Bobby Bingham
179 John Spencer
180 Nicholas J. Kain
181 Rich Felker
182 Richard Pennington
183 Stefan Kristiansson
184 Szabolcs Nagy
185
186 all of whom have explicitly granted such permission.
187
188 This file previously contained text expressing a belief that most of
189 the files covered by the above exception were sufficiently trivial not
190 to be subject to copyright, resulting in confusion over whether it
191 negated the permissions granted in the license. In the spirit of
192 permissive licensing, and of not having licensing issues being an
193 obstacle to adoption, that text has been removed.
