@gvanrossum this PR fixes a regression from the except* PR and it’s all very odd, both the bug and the impact of the fix.

I extracted it out of the test. I think with this PR it emits the finally body 4 times, and without it 3 times?

We sometimes duplicate exit blocks to save a jump, but only if they have 4 or fewer instructions.

Maybe the explicit jump prevents that?

I'm going to assume that this is what happened (this jump prevented an inlining optimization), and remove it as in the first version of this PR. This will being us back to where we were before the except* PR was merged.

I think we should probably merge this before the release so that we don’t get a change in behaviour between 3.11a3 and 311.a4.

I agree.
This PR merely highlights the excessive duplication of finally blocks. It doesn't cause it.
Do we have an issue to investigate the cause of finally block duplication?

Does this cover the original issue?
The compiler will optimize out the if False.
Might be a good idea to add another test with a non-constant predicate.

The test did fail without the fix. But sure, I'll add a test with a non const.
