-# ====================================================================
-# Written by Andy Polyakov <appro@fy.chalmers.se> for the OpenSSL
-# project. The module is, however, dual licensed under OpenSSL and
-# CRYPTOGAMS licenses depending on where you obtain it. For further
-# details see http://www.openssl.org/~appro/cryptogams/.
-# ====================================================================

-# Performance improvement is not really impressive on pre-T1 CPU: +8%
-# over Sun C and +25% over gcc [3.3]. While on T1, a.k.a. Niagara, it
-# turned to be 40% faster than 64-bit code generated by Sun C 5.8 and
-# >2x than 64-bit code generated by gcc 3.4. And there is a gimmick.
-# X[16] vector is packed to 8 64-bit registers and as result nothing
-# is spilled on stack. In addition input data is loaded in compact
-# instruction sequence, thus minimizing the window when the code is
-# subject to [inter-thread] cache-thrashing hazard. The goal is to
-# ensure scalability on UltraSPARC T1, or rather to avoid decay when
-# amount of active threads exceeds the number of physical cores.
