It looks almost all AArch64 cores agree on alignment of 16 for function, and 8 for loops and branches, so we should change -mcpu=generic as well if there is no disagreement - feedback welcome.
I'll see what sets of values Exynos M1 would be most comfortable with,
but I also wonder if the -falign-labels shouldn't also be a parameter in
tune_params.
Thoughts?
