sse-popcount's Issues

AVX2 & popcnt mix

Use AVX2 instructions to load data, then use YMM registers as a source for popcnt instructions. I'm curious how fast it will be.

Cannot compile popcnt-avx2-harley-seal.cpp using MSVC 2015

Hi Wojciech,

I use your popcnt-avx2-harley-seal algorithm in my libpopcnt.h. Unfortunately it fails to compile on Windows using a recent MSVC 2015 compiler version:

Stop.

It seems like the MSVC compiler has poor AVX2 support (e.g. the _mm256_extract_epi64 intrinsic seems to be missing)!? Have you ever tried compiling your sse-popcount project using MSVC?

Here is a link to my libpopcnt.h

Thanks,
Kim
