* [3.13] gh-119821: Support non-dict globals in LOAD_FROM_DICT_OR_GLOBALS ↵Jelle Zijlstra2024-06-011-9/+26
| | | | | | | | | | | | | (#119822) (#119889) dSupport non-dict globals in LOAD_FROM_DICT_OR_GLOBALS The implementation basically copies LOAD_GLOBAL. Possibly it could be deduplicated, but that seems like it may get hairy since the two operations have different operands. This is important to fix in 3.14 for PEP 649, but it's a bug in earlier versions too, and we should backport to 3.13 and 3.12 if possible. (cherry picked from commit 80a4e3899420faaa012c82b4e82cdb6675a6a944)

* gh-118335: Configure Tier 2 interpreter at build time (#118339)Guido van Rossum2024-05-011-0/+6
| | | | | | | | | | | | | | | | | | | | | | The code for Tier 2 is now only compiled when configured with `--enable-experimental-jit[=yes|interpreter]`. We drop support for `PYTHON_UOPS` and -`Xuops`, but you can disable the interpreter or JIT at runtime by setting `PYTHON_JIT=0`. You can also build it without enabling it by default using `--enable-experimental-jit=yes-off`; enable with `PYTHON_JIT=1`. On Windows, the `build.bat` script supports `--experimental-jit`, `--experimental-jit-off`, `--experimental-interpreter`. In the C code, `_Py_JIT` is defined as before when the JIT is enabled; the new variable `_Py_TIER2` is defined when the JIT *or* the interpreter is enabled. It is actually a bitmask: 1: JIT; 2: default-off; 4: interpreter.

* gh-116818: Make `sys.settrace`, `sys.setprofile`, and monitoring thread-safe ↵Dino Viehland2024-04-191-5/+13
| | | | | | | (#116775) Makes sys.settrace, sys.setprofile, and monitoring generally thread-safe. Mostly uses a stop-the-world approach and synchronization around the code object's _co_instrumentation_version. There may be a little bit of extra synchronization around the monitoring data that's required to be TSAN clean.

* gh-116968: Reimplement Tier 2 counters (#117144)Guido van Rossum2024-04-041-50/+37
| | | | | | | | | | | | Introduce a unified 16-bit backoff counter type (``_Py_BackoffCounter``), shared between the Tier 1 adaptive specializer and the Tier 2 optimizer. The API used for adaptive specialization counters is changed but the behavior is (supposed to be) identical. The behavior of the Tier 2 counters is changed: - There are no longer dynamic thresholds (we never varied these). - All counters now use the same exponential backoff. - The counter for ``JUMP_BACKWARD`` starts counting down from 16. - The ``temperature`` in side exits starts counting down from 64.

* gh-116760: Fix pystats for trace attempts (GH-116761)Michael Droettboom2024-03-131-1/+0
| | | | | | | | There are now at least two bytecodes that may attempt to optimize, JUMP_BACK, and more recently, COLD_EXIT. Only the JUMP_BACK was counting the attempt in the stats. This moves that counter to uop_optimize itself so it should always happen no matter where it is called from.

* gh-112175: Add `eval_breaker` to `PyThreadState` (#115194)Brett Simmers2024-02-201-3/+3
| | | | | | | | | | | This change adds an `eval_breaker` field to `PyThreadState`. The primary motivation is for performance in free-threaded builds: with thread-local eval breakers, we can stop a specific thread (e.g., for an async exception) without interrupting other threads. The source of truth for the global instrumentation version is stored in the `instrumentation_version` field in PyInterpreterState. Threads usually read the version from their local `eval_breaker`, where it continues to be colocated with the eval breaker bits.
