+// 2024-02-22: Feedback from benchmarks:
+//   - Brancless C (0x003) can be better than basic on x86-64 but often it's
+//     slightly worse on other archs. Since asm is much better on x86-64,
+//     branchless C is not used at all.
+//   - With x86-64 asm, there are slight differences between GCC and Clang
+//     and different processors. Overall 0x1F0 seems to be the best choice.
