-// Based on CRYPTOGAMS code with the following comment:
-// # ====================================================================
-// # Written by Andy Polyakov <appro@openssl.org> 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/.

-
-// There are some differences between CRYPTOGAMS code and this one. The round
-// loop for "_int" isn't the same as the original. Some adjustments were
-// necessary because there are less vector registers available.  For example, some
-// X variables (r12, r13, r14, and r15) share the same register used by the
-// counter. The original code uses ctr to name the counter. Here we use CNT
-// because golang uses CTR as the counter register name.
