musl - an implementation of the standard library for Linux-based systems
07616721f1
As a result of using simple subtraction to implement the return values for wcscmp and wcsncmp, integer overflow can occur (producing undefined behavior, and in practice, a wrong comparison result). This does not occur for meaningful character values (21-bit range) but the functions are specified to work on arbitrary wchar_t arrays. This patch replaces the subtraction with a little bit of code that orders the characters correctly, returning -1 if the character from the first string is smaller than the one from the second, 0 if they are equal and 1 if the character from the first string is larger than the one from the second. |

musl libc
musl, pronounced like the word "mussel", is an MIT-licensed
implementation of the standard C library targetting the Linux syscall
API, suitable for use in a wide range of deployment environments. musl
offers efficient static and dynamic linking support, lightweight code
and low runtime overhead, strong fail-safe guarantees under correct
usage, and correctness in the sense of standards conformance and
safety. musl is built on the principle that these goals are best
achieved through simple code that is easy to understand and maintain.
The 1.1 release series for musl features coverage for all interfaces
defined in ISO C99 and POSIX 2008 base, along with a number of
non-standardized interfaces for compatibility with Linux, BSD, and
glibc functionality.
For basic installation instructions, see the included INSTALL file.
Information on full musl-targeted compiler toolchains, system
bootstrapping, and Linux distributions built on musl can be found on
