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.

To run unit and validation tests type make test_ARCH, to run performance tests type make run_ARCH. Value ARCH selectes the CPU architecture:

• sse4,
• avx2,
• avx512f,
• avx512bw,
• arm,
• aarch64.

The subdirectory results contains raw timings from various computers.
