The happy path is 401160 through 401185. The unwinding code no more dilutes the code cache than any other subsequent and possibly unrelated functions in memory.

The happy path is 401160 through 401185. The unwinding code no more dilutes the code cache than any other subsequent and possibly unrelated functions in memory. The unwinding code is not there to make it faster since it's generally reached after walking the stack twice. It's moved out of the happy path to make the happy path faster since it doesn't dilute the instruction cache and doesn't hit the pipeline.
