5 // This source file uses intrinsics to gain access to ARMv7a/ARMv8a
6 // NEON, Power7 and SSE4.1 instructions. A separate source file is
7 // needed because additional CXXFLAGS are required to enable the
8 // appropriate instructions sets in some build configurations.

10 // The BLAKE2b and BLAKE2s numbers are consistent with the BLAKE2 team's
11 // numbers. However, we have an Altivec/POWER7 implementation of BLAKE2s,
12 // and a POWER8 implementation of BLAKE2b (BLAKE2 is missing them). The
13 // Altivec/POWER7 code is about 2x faster than C++ when using GCC 5.0 or
14 // above. The POWER8 code is about 2.5x faster than C++ when using GCC 5.0
15 // or above. If you use GCC 4.0 (PowerMac) or GCC 4.8 (GCC Compile Farm)
16 // then the PowerPC code will be slower than C++. Be sure to use GCC 5.0
17 // or above for PowerPC builds or disable Altivec for BLAKE2b and BLAKE2s
18 // if using the old compilers.
