GH-103082: Implementation of PEP 669: Low Impact Monitoring for CPython (GH-103083) 
* The majority of the monitoring code is in instrumentation.c

* The new instrumentation bytecodes are in bytecodes.c

* legacy_tracing.c adapts the new API to the old sys.setrace and sys.setprofile APIs

gh-102674: Remove _specialization_stats from Lib/opcode.py (#102685) 
It's not use except in a test, so move it there instead.

GH-98686: Get rid of "adaptive" and "quick" instructions (GH-99182) 2022-11-09 10:50:09 -08:00

GH-96793: Change `FOR_ITER` to not pop the iterator on exhaustion. (GH-96801) 
Change FOR_ITER to have the same stack effect regardless of whether it branches or not.
Performance is unchanged as FOR_ITER (and specialized forms jump over the cleanup code).

bpo-33334: Support NOP and EXTENDED_ARG in dis.stack_effect(). (#6566) 
Added tests to ensure that all defined opcodes are supported.

Zachary Ware 38c707e7e0 Issue #21741: Update 147 test modules to use test discovery. 
I have compared output between pre- and post-patch runs of these tests
to make sure there's nothing missing and nothing broken, on both
Windows and Linux.  The only differences I found were actually tests
that were previously *not* run.

Larry Hastings c8635b4192 Don't attempt to run the _opcode test if it wasn't built. 2013-11-23 16:11:17 -08:00
Larry Hastings 3a9079742f Issue #19722: Added opcode.stack_effect(), which accurately 
computes the stack effect of bytecode instructions.
