The 102included version has been heavily modified by Rich Felker in 2012, in 103the interests of size, simplicity, and namespace cleanliness. 104 105Much of the math library code (src/math/* and src/complex/*) is 106Copyright © 1993,2004 Sun Microsystems or 107Copyright © 2003-2011 David Schultz or 108Copyright © 2003-2009 Steven G.

It was taken from Bionic libc, used on Android. 117 118The implementation of DES for crypt (src/crypt/crypt_des.c) is 119Copyright © 1994 David Burren. It is licensed under a BSD license. 120 121The implementation of blowfish crypt (src/crypt/crypt_blowfish.c) was 122originally written by Solar Designer and placed into the public 123domain. The code also comes with a fallback permissive license for use 124in jurisdictions that may not recognize the public domain. 125 126The smoothsort implementation (src/stdlib/qsort.c) is Copyright © 2011 127Valentin Ochs and is licensed under an MIT-style license. 128 129The x86_64 port was written by Nicholas J. Kain and is licensed under 130the standard MIT terms. 131 132The mips and microblaze ports were originally written by Richard 133Pennington for use in the ellcc project. The original code was adapted 134by Rich Felker for build system and code conventions during upstream 135integration. It is licensed under the standard MIT terms. 136 137The mips64 port was contributed by Imagination Technologies and is 138licensed under the standard MIT terms. 139 140The powerpc port was also originally written by Richard Pennington, 141and later supplemented and integrated by John Spencer. It is licensed 142under the standard MIT terms. 143 144All other files which have no copyright comments are original works 145produced specifically for use as part of this library, written either 146by Rich Felker, the main author of the library, or by one or more 147contibutors listed above. Details on authorship of individual files 148can be found in the git version control history of the project. The 149omission of copyright and license comments in each file is in the 150interest of source tree size. 151 152In addition, permission is hereby granted for all public header files 153(include/* and arch/*/bits/*) and crt files intended to be linked into 154applications (crt/*, ldso/dlstart.c, and arch/*/crt_arch.h) to omit 155the copyright notice and permission notice otherwise required by the 156license, and to use these files without any requirement of 157attribution. These files include substantial contributions from: 158 159Bobby Bingham 160John Spencer 161Nicholas J. Kain 162Rich Felker 163Richard Pennington 164Stefan Kristiansson 165Szabolcs Nagy 166 167all of whom have explicitly granted such permission. 168 169This file previously contained text expressing a belief that most of 170the files covered by the above exception were sufficiently trivial not 171to be subject to copyright, resulting in confusion over whether it 172negated the permissions granted in the license. In the spirit of 173permissive licensing, and of not having licensing issues being an 174obstacle to adoption, that text has been removed. 175
