Mips is tier 3, but it probably still makes sense to backport this, as the target is currently completely broken.

(The nomination is for the next beta, not the upcoming stable.)

It seems you included your own Nov 3 commit of "[GlobalOpt] Cache whether CC is changeable", before it landed on main on Nov 7 and was backported to 17.x on Nov 14 (today). Not a big deal, since the commits were identical and so the merge was clean -- just noting the difference in commit history.

Ooops, I forgot to reset my branch before merging.

Maybe bump here too?

@klensy that update can be done separately, and I think doesn't need beta backport.

Oh, beta, ok.
