Guido van Rossum	51fc725117	gh-104584: Baby steps towards generating and executing traces (#105924 ) 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.	2023-06-26 19:02:57 -07:00

gh-105775: Convert LOAD_CLOSURE to a pseudo-op (#106059 )

This enables super-instruction formation,
removal of checks for uninitialized variables,
and frees up an instruction.
