This patch fixes that by setting the default aarch64_case_values_threshold to 16 when the per-CPU tuning is not set. On SPEC2006 this improves the switch heavy benchmarks GCC and perlbench both in performance (1-2%) as well as size (0.5-1% smaller).
I assume that you mean that such improvements are true for -mcpu=generic, yes? On which target, A53 or A57 or other?
Otherwise, it seems to be a sensible change, but I'm trying to understand how generally beneficial it is.
