*	chapoly: Process two Poly1305 blocks in parallel in SSSE3 driver	Martin Willi	2015-07-12	1	-85/+291
\| \| \| \| \| \| \| \| \| \|	By using a derived key r^2 we can improve performance, as we can do loop unrolling and slightly better utilize SIMD instructions. Overall ChaCha20-Poly1305 performance increases by ~12%. Converting integers to/from our 5-word representation in SSE does not seem to pay off, so we work on individual words.
*	chapoly: Process four ChaCha20 blocks in parallel in SSSE3 driver	Martin Willi	2015-07-12	1	-16/+207
\| \| \| \| \|	As we don't have to shuffle the state in each ChaCha round, overall performance for ChaCha20-Poly1305 increases by ~40%.
*	chapoly: Add an SSSE3 based driver	Martin Willi	2015-06-29	4	-1/+514
\| \| \| \| \| \| \| \| \| \| \| \| \|	We always build the driver on x86/x64, but enable it only if SSSE3 support is detected during runtime. Poly1305 uses parallel 32-bit multiplication operands yielding a 64-bit result, for which two can be done in parallel in SSE. This is minimally faster than multiplication with 64-bit operands, and also works on 32-bit builds not having a __int128 result type. On a 32-bit architecture, this is more than twice as fast as the portable driver, and on 64-bit it is ~30% faster.
