liboil0.3

Library of Optimized Inner Loops
Liboil is a collection of functions that often benefit from having
special implementations on various architectures or CPUs. Each function
in liboil has several implementations which may perform faster or
slower on a given CPU. Some implementations use alternate algorithms,
some use hand-crafted assembly, and some use special instructions that
are only available on certain CPUs, such as MMX, SSE, or Altivec.
The fastest implementation is automatically chosen at runtime.
