How much is it? 1%? Maybe 2%? More? The performance impact will be definitely less than 1% with that size increase one integer size. It should be almost not measurable. The value is only "long long". The size field can use a bit field without increase the structure size. I will send out that change later. You said you did not found crash in your first round testing. However there is some regression of the IR. Can you share the regression test case you found?
