Pull request details were added to CHANGELOG.rst
Documentation was updated (if needed)
Simplify data structures to allow for easier vectorization.
Utilize dynamic dispatch to write a single AVX2 algorithm, which can handle cases of 2,3 or 4 matchers with equal efficiency.
No more reliance on
#ifdef __SSE2__
throughout the code.Fixes #211
Fixes #171 . The autovectorization is simply is not productive enough. A hand-written avx2 implementation is much faster than whaver auto-vectorization can produce. I tested this using GCC14. As such it is better to write a separate ARM-based implementation when the need arises.
