Call stats are incorrect for tier 2 and maybe for tier 1 as well #118036
Description
Bug report
Bug description:
The call stats for tier 2 differ significantly from tier 1, but it is not clear that the tier 1 call stats are correct either.
The main purpose of the call stats is to track the fraction of Python frames that are created with and without calls to PyEval_EvalDefault. However, the stats don't make that clear and may be incorrect.
Currently the table looks like this:
| Count | Ratio | |
|---|---|---|
| Calls to PyEval_EvalDefault | 2,309,411,110 | 32.0% |
| Calls to Python functions inlined | 4,908,275,087 | 68.0% |
| Calls via PyEval_EvalFrame (total) | 2,309,411,110 | 32.0% |
| Calls via PyEval_EvalFrame (vector) | 1,447,866,962 | 20.1% |
| Calls via PyEval_EvalFrame (generator) | 861,544,148 | 11.9% |
| Calls via PyEval_EvalFrame (legacy) | 4,418,464 | 0.1% |
| Calls via PyEval_EvalFrame (function vectorcall) | 1,443,417,872 | 20.0% |
| Calls via PyEval_EvalFrame (build class) | 30,626 | 0.0% |
| Calls via PyEval_EvalFrame (slot) | 475,837,706 | 6.6% |
| Calls via PyEval_EvalFrame (function ex) | 38,365,096 | 0.5% |
| Calls via PyEval_EvalFrame (api) | 256,353,600 | 3.6% |
| Calls via PyEval_EvalFrame (method) | 213,159,135 | 3.0% |
| Frame objects created | 88,466,853 | 1.2% |
| Frames pushed | 4,953,781,868 | 68.6% |
Note that the numbers don't add up.
The number of "frames pushed" is actually the total number of frames created. As it is function frames pushed, generator frames are not counted.
Frame objects created should be a fraction of "frames created". All other numbers should be a fraction of "frames pushed"

GH-118036: Fix a bug with CALL_STAT_INC (#117933)

Could you clarify which numbers you expect to add up?
