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 implementation of BLAKE2s, |
12 | | // and a POWER8 implementation of BLAKE2b (BLAKE2 team is missing them). |
13 | | // Altivec 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. |
