Created for 64-bit little-endian platforms, in predominantly for x86_64, * but portable and without penalties it can run on any 64-bit CPU. * 2. In most cases up to 15% faster than City64, xxHash, mum-hash, metro-hash * and all others portable hash-functions (which do not use specific * hardware tricks). * 3. Not suitable for cryptography. * * The Future will Positive. Всё будет хорошо. * * ACKNOWLEDGEMENT: * The t1ha was originally developed by Leonid Yuriev (Леонид Юрьев) * for The 1Hippeus project - zerocopy messaging in the spirit of Sparta! */ #pragma once #if defined(_MSC_VER) && _MSC_VER > 1800 #pragma warning(disable : 4464) /* relative include path contains '..' */ #endif /* MSVC */ #include "t1ha.h" /***************************************************************************/ /* Self-checking */ extern const uint8_t t1ha_test_pattern[64]; int t1ha_selfcheck(uint64_t (*hash)(const void *, size_t, uint64_t), const uint64_t *reference_values); #ifndef T1HA2_DISABLED extern const uint64_t t1ha_refval_2atonce[81]; extern const uint64_t t1ha_refval_2atonce128[81]; extern const uint64_t t1ha_refval_2stream[81]; extern const uint64_t t1ha_refval_2stream128[81]; #endif /* T1HA2_DISABLED */ #ifndef T1HA1_DISABLED extern const uint64_t t1ha_refval_64le[81]; extern const uint64_t t1ha_refval_64be[81]; #endif /* T1HA1_DISABLED */ #ifndef T1HA0_DISABLED extern const uint64_t t1ha_refval_32le[81]; extern const uint64_t t1ha_refval_32be[81]; #if T1HA0_AESNI_AVAILABLE extern const uint64_t t1ha_refval_ia32aes_a[81]; extern const uint64_t t1ha_refval_ia32aes_b[81]; #endif /* T1HA0_AESNI_AVAILABLE */ #endif /* T1HA0_DISABLED */
