musl - an implementation of the standard library for Linux-based systems
39e43f0881
powl used >= LDBL_MAX as infinity check, but LDBL_MAX is finite, so this can cause wrong results e.g. powl(LDBL_MAX, 0.5) returned inf or powl(2, LDBL_MAX) returned inf without raising overflow. huge y values (close to LDBL_MAX) could cause intermediate results to overflow (computing y * log2(x) with more than long double precision) and e.g. powl(0.5, 0x1p16380L) or powl(10, 0x1p16380L) returned nan. this is fixed by handling huge y early since that always overflows or underflows. reported by Paul Zimmermann against expl10 (which uses powl). |

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
the project website:
