* gh-114058: More robust method handling in redundancy eliminator (GH-115779)Ken Jin2024-02-231-0/+1

* GH-115651: Convert `LOAD_MODULE_ATTR` into `LOAD_INLINE_CONST` when the ↵Mark Shannon2024-02-221-24/+44
| | | | module is itself a constant. (GH-115711)
* Delete unused sym_clear_flag function. (#115744)Benjamin Peterson2024-02-211-6/+0

* Tier 2 cleanups and tweaks (#115534)Guido van Rossum2024-02-201-1/+2
| | | | | | | | | * 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
