I tried this patch on aarch64 A72 firefly linux on a set of benchmarks.
Overall the performance improved by 11% cumulatively (sum of all speedups and slowdowns.)
7 benchmarks improved by more than 1% and 4 degraded by >1%, one degraded by 4% and another by 3%.
I will investigate the 4% and 3% regressions.
