Quadsort is a branchless stable adaptive mergesort faster than quicksort.

As you can see, quadsort 1.1.4.1 used 2 instead of 4 writes in the bi-directional parity merges. This was in June 2021, and would have compiled as branchless with clang, but as branched with gcc.
When I added a compile time check to use ternary operations for clang I was not adapting your work. I was well aware that clang compiled ternary operations as branchless, but I wasn't aware that rust did as well. I added the compile time check to use ternary operations for a fair performance comparison against glidesort.

As for ipnsort's small sort, it is very similar to quadsort's small sort, which uses stable sorting networks, instead of unstable sorting networks. From my perspective it's not exactly novel. I didn't go for unstable sorting networks in crumsort to increase code reuse, and to not reduce adaptivity.
