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
Mark Shannon	581619941e	GH-104584: Assorted fixes for the optimizer API. (GH-105683) ... * Add test for long loops * Clear ENTER_EXECUTOR when deopting code objects.	2023-06-19 10:32:20 +01:00
Mark Shannon	7199584ac8	GH-100987: Allow objects other than code objects as the "executable" of an internal frame. (GH-105727) ... * Add table describing possible executable classes for out-of-process debuggers. * Remove shim code object creation code as it is no longer needed. * Make lltrace a bit more robust w.r.t. non-standard frames.	2023-06-14 13:46:37 +01:00
