// blake2_simd.cpp - written and placed in the public domain by

|

// This source file uses intrinsics to gain access to ARMv7a/ARMv8a
|
||
|
// NEON, Power7 and SSE4.1 instructions. A separate source file is
|
||
|
// needed because additional CXXFLAGS are required to enable the
|
||
|
// appropriate instructions sets in some build configurations.
|
||
|
|
||
|
// The BLAKE2b and BLAKE2s numbers are consistent with the BLAKE2 team's
|
||
|
// numbers. However, we have an Altivec implementation of BLAKE2s,
|
||
|
// and a POWER8 implementation of BLAKE2b (BLAKE2 team is missing them).
|
||
|
// Altivec code is about 2x faster than C++ when using GCC 5.0 or
|
||
|
// above. The POWER8 code is about 2.5x faster than C++ when using GCC 5.0
|
||
|
// or above. If you use GCC 4.0 (PowerMac) or GCC 4.8 (GCC Compile Farm)
|
||
|
// then the PowerPC code will be slower than C++. Be sure to use GCC 5.0
|
||
|
// or above for PowerPC builds or disable Altivec for BLAKE2b and BLAKE2s
|
||
|
// if using the old compilers.
