--- Comment #9 from Andy Lutomirski <luto at kernel dot org> ---
I haven't fully dug into this, but I do one one immediate question: why is GCC
generating a jump table for a five-entry switch statement if retpolines are on?
This has got to be a *huge* performance loss. The retpoline sequence is very,
very slow, and branches aren't that slow. A five-entry switch is only three
branches deep.
