Using the benchmarks in#101011 (comment), but usingtimeit instead ofpyperf and a non-pgo and no-lto build because I'm impatient.
I get no significant change on "comprehension", "generator exhaust", and "all", but runtime is about 60% for "generator" and "all with comparison"

I guess this will not be easy to backport, as we won't want to change the meaning of oparg in 3.11?

I think a similar change in 3.11 would actually be simpler: just check if an exception table exists. If not, don't throw.

The only reason we need theYIELD_VALUE oparg in this 3.12 patch is because every generator now has an implicittry/except around the entire body, so it's a bit trickier to figure out if we're in that handler (which we can safely ignore) or something else.

Great, it'll just bedifferent. :-)

I don’t think this should be backported as-is, right? (See my comment above.)

@brandtbucher agreed.
The changes to genobject.c need backporting (with the change you suggest for determining when to skip the call togen.throw(), but the other changes are 3.12 specific.
