* gh-106023: Update code using _PyObject_FastCall() (#106257)Victor Stinner2023-06-301-135/+135
| | | Replace _PyObject_FastCall() calls with PyObject_Vectorcall().
* GH-106008: Make implicit boolean conversions explicit (GH-106003)Brandt Bucher2023-06-291-241/+331

* gh-105775: Convert LOAD_CLOSURE to a pseudo-op (#106059)hms2023-06-291-127/+127
| | | | | | This enables super-instruction formation, removal of checks for uninitialized variables, and frees up an instruction.
* gh-104584: Add #line directives to executor_cases.c.h (#106126)Guido van Rossum2023-06-271-0/+254

* gh-104584: Baby steps towards generating and executing traces (#105924)Guido van Rossum2023-06-271-0/+1606
Added a new, experimental, tracing optimizer and interpreter (a.k.a. "tier 2"). This currently pessimizes, so don't use yet -- this is infrastructure so we can experiment with optimizing passes. To enable it, pass ``-Xuops`` or set ``PYTHONUOPS=1``. To get debug output, set ``PYTHONUOPSDEBUG=N`` where ``N`` is a debug level (0-4, where 0 is no debug output and 4 is excessively verbose). All of this code is likely to change dramatically before the 3.13 feature freeze. But this is a first step.
