You should not need C++20 to build CRoaring.
Yes, this looks possible now.
@wshager I am somewhat pessimistic regarding any approach that does not translate into SIMD instructions at the machine level.
@wshager Can you tell us which examples fare well and which ones fare badly?
What happens after this last commit https://github.com/lemire/simdcomp/commit/b7e1ecca96ebb5290c52e3738fb844e2436ffa74 ?
Ok. Can you share the resulting output (just so we can document it).
@wshager Thanks, but I am inviting you to publish the performance results you got. My concern right now is whether SIMD instructions are used at all. On my laptop, the...
@wshager Do you have the screen output where it compares the memcpy speed with the decoding speed? On my Firefox, things just freeze, so it is no use. On Google...
@wshager These results are better than what I get with Google Chrome but still not close to what one would want. These results are thousands of times slower than C....
@wshager Yes, manual inspection of the generated code might be telling.
