* gh-106320: Fix specialize.c compilation by including pycore_pylifecycle.h ↵Guido van Rossum2023-07-041-0/+1

* gh-104584: Baby steps towards generating and executing traces (#105924)Guido van Rossum2023-06-271-0/+4
| | | | | 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.
