The param is changed here:

and so that it should be per-function. The only usage is in combine RTL
pass, which is per-function optimization.
Patch can bootstrap on x86_64-linux-gnu and survives regression tests.
Ready to be installed?
Sure. Okay for trunk. Thanks!
Thank you.

* params.opt: Mart param_max_combine_insns with Optimization
keyword.

Will fix the typo.
(Btw, does this help -Og at all? If so, shouldn't it be -O1 as well?)
I would say yes. The param default for -Og was added by Richi in 2014.
I'm adding him to CC.
