| | | | objects. (GH-116115)
* Fix broken format in error for bad input in summarize_stats.py (#117375)Guido van Rossum2024-03-291-1/+1
| | | When you pass the script a non-existent input file, you get a TypeError instead of the intended ValueError.

* Tier 2 cleanups and tweaks (#115534)Guido van Rossum2024-02-201-0/+4
| | | | | | | | | * Rename `_testinternalcapi.get_{uop,counter}_optimizer` to `new_*_optimizer` * Use `_PyUOpName()` instead of` _PyOpcode_uop_name[]` * Add `target` to executor iterator items -- `list(ex)` now returns `(opcode, oparg, target, operand)` quadruples * Add executor methods `get_opcode()` and `get_oparg()` to get `vmdata.opcode`, `vmdata.oparg` * Define a helper for printing uops, and unify various places where they are printed * Add a hack to summarize_stats.py to fix legacy uop names (e.g. `POP_TOP` -> `_POP_TOP`) * Define helpers in `test_opt.py` for accessing the set or list of opnames of an executor

| | | | | | | | | | This adds support for comparing pystats collected from two different builds. - The `--json-output` can be used to load in a set of raw stats and output a JSON file. - Two of these JSON files can be provided on the next run, and then comparative results between the two are output.
