-# project. The module is, however, dual licensed under OpenSSL and
-# CRYPTOGAMS licenses depending on where you obtain it. For further

-# The module implements bn_GF2m_mul_2x2 polynomial multiplication used
-# in bn_gf2m.c. It's kind of low-hanging mechanical port from C for
-# the time being... Except that it has two code paths: one suitable
-# for all SPARCv9 processors and one for VIS3-capable ones. Former
-# delivers ~25-45% more, more for longer keys, heaviest DH and DSA
-# verify operations on venerable UltraSPARC II. On T4 VIS3 code is
-# ~100-230% faster than gcc-generated code and ~35-90% faster than
-# the pure SPARCv9 code path.
