v11.1

When primesieve is distributed via distro package managers, it is often not compiled using the highest optimization level -O3. Because of this primesieve's pre-sieving algorithm was not auto-vectorized in many cases. As a workaround for this issue I have now manually vectorized the pre-sieving algorithm for x64 CPUs (using portable SSE2) and for ARM64 CPUs (using portable ARM NEON). This can improve performance by up to 40%.

  • PreSieve.cpp: Vectorize loop using x64 SSE2 & ARM NEON.
  • popcount.cpp: Add POPCNT algorithm for x64 & AArch64.
  • primesieve.h: Fix -Wstrict-prototypes warning.
  • examples/c/*.c: Fix -Wstrict-prototypes warning.
  • test/*.c: Fix -Wstrict-prototypes warning.
  • CMakeLists.txt: New WITH_AUTO_VECTORIZATION option (with default ON).
  • cmake/auto_vectorize.cmake: Enable auto-vectorization if the compiler supports it.
  • scripts/build_mingw64_x64.sh: Build primesieve x64 release binary.
  • scripts/build_mingw64_arm64.sh: Build primesieve arm64 release binary.
