CentOS 7 - Updates for x86_64: development/libraries: liboil-devel
liboil-devel - Development files and static library for liboil
Liboil is a library of simple functions that are optimized for various CPUs.
These functions are generally loops implementing simple algorithms, such as
converting an array of N integers to floating-poing numbers or multiplying
and summing an array of N numbers. Clearly such functions are candidates for
significant optimization using various techniques, especially by using
extended instructions provided by modern CPUs (Altivec, MMX, SSE, etc.).
