*	GH-100288: regen cases after #105990 (#106589)	Kumar Aditya	2023-07-10	1	-7/+7

*	GH-100288: Specialize LOAD_ATTR for simple class attributes. (#105990)	Mark Shannon	2023-07-10	1	-35/+35
\| \| \|	* Add two more specializations of LOAD_ATTR.
*	gh-104584: Allow unspecialized instructions in superblocks (#106497)	Guido van Rossum	2023-07-07	1	-126/+430
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	This adds several of unspecialized opcodes to superblocks: TO_BOOL, BINARY_SUBSCR, STORE_SUBSCR, UNPACK_SEQUENCE, LOAD_GLOBAL, LOAD_ATTR, COMPARE_OP, BINARY_OP. While we may not want that eventually, for now this helps finding bugs. There is a rudimentary test checking for UNPACK_SEQUENCE. Once we're ready to undo this, that would be simple: just replace the call to variable_used_unspecialized with a call to variable_used (as shown in a comment). Or add individual opcdes to FORBIDDEN_NAMES_IN_UOPS.
*	GH-106057: Handle recursion errors in inline class calls properly. (GH-106108)	Mark Shannon	2023-07-07	1	-10/+10
\|
*	GH-104584: Fix ENTER_EXECUTOR (GH-106141)	Mark Shannon	2023-07-03	1	-22/+22
\| \| \| \| \| \|	* Check eval-breaker in ENTER_EXECUTOR. * Make sure that frame->prev_instr is set before entering executor.
*	gh-106290: Fix edge cases around uops (#106319)	Guido van Rossum	2023-07-03	1	-135/+156
\| \| \| \| \| \| \| \| \| \|	- Tweak uops debugging output - Fix the bug from gh-106290 - Rename `SET_IP` to `SAVE_IP` (per https://github.com/faster-cpython/ideas/issues/558) - Add a `SAVE_IP` uop at the start of the trace (ditto) - Allow `unbound_local_error`; this gives us uops for `LOAD_FAST_CHECK`, `LOAD_CLOSURE`, and `DELETE_FAST` - Longer traces - Support `STORE_FAST_LOAD_FAST`, `STORE_FAST_STORE_FAST` - Add deps on pycore_uops.h to Makefile(.pre.in)
*	gh-106267: Add type cast to generated code (#106289)	Kirill Podoprigora	2023-06-30	1	-1/+1
\|
*	gh-106023: Update code using _PyObject_FastCall() (#106257)	Victor Stinner	2023-06-30	1	-135/+135
\| \| \|	Replace _PyObject_FastCall() calls with PyObject_Vectorcall().
*	GH-106008: Make implicit boolean conversions explicit (GH-106003)	Brandt Bucher	2023-06-29	1	-241/+331
\|
*	gh-105775: Convert LOAD_CLOSURE to a pseudo-op (#106059)	hms	2023-06-29	1	-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 Rossum	2023-06-27	1	-0/+254

*	gh-104584: Baby steps towards generating and executing traces (#105924)	Guido van Rossum	2023-06-27	1	-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.
