Tidy does not run inside the cg_clif and cg_gcc repos, which means whenever we do a sync, there is a fair chance that we did be forced to male changes when tidy complains.

I would suggest not running full tidy against the cg_* subtrees yeah.

Also, doesn't rust-lang/compiler-team#963 only say TODO -> FIXME? Not other tidy checks? I do not think we should be enforcing other tidy rules for the cg_* subtrees.

Ah, I overinterpreted it — my mistake. Thanks for the clarification. I’ll update it accordingly.
