================================================================================ SIMD-friendly algorithms for substring searching
Sample programs for article "SIMD-friendly algorithms for substring searching" (http://0x80.pl/articles/simd-strfind.html).
The root directory contains C++11 procedures implemented using intrinsics for SSE, SSE4, AVX2, AVX512F, AVX512BW and ARM Neon (both ARMv7 and ARMv8).
The subdirectory original contains 32-bit programs with inline assembly, written in 2008 for another article__.
