What about Highway? https://github.com/google/highway I suppose that's C++ not C though.

Static search trees: 40x faster than binary search
google has a mature C++ library for portable SIMD. The original article seems to be a translation of the excellent algorithmica site which had it in C++.

Why those particular integer multiplies?
> Or do they somehow adapt to the operations supported by the user's CPU?
This is called runtime dispatch. You can do it manually or use a library, like Google Highway. GCC supports multiversioning where you write separate versions of a function and the right one is selected at runtime.

Apple's M4 Has Reportedly Adopted the ARMv9 Architecture
It's great you bring up cmp, helps to understand why 4x128 is not necessarily as good as 1x512. Quicksort, hardly a 'weird kernel', does comparisons followed by compaction. Because comparisons return a predicate, which have only a single write port, we can only do 128 bits of comparisons per cycle. Ouch.
However, masking can still help our VQSort [1], for example when writing the rightmost partition right to left without stomping on subsequent elements, or in a sorting network, only updating every second element.

It's also mentioned in [1], which starts off
> Today we're sharing open source code that can sort arrays of numbers about ten times as fast as the C++ std::sort, and outperforms state of the art architecture-specific algorithms, while being portable across all modern CPU architectures. Below we discuss how we achieved this.
