* GH-115802: Use the GHC calling convention in JIT code (GH-118287)Brandt Bucher2024-05-014-11/+76

* gh-118335: Configure Tier 2 interpreter at build time (#118339)Guido van Rossum2024-05-012-3/+4
| | | | | | | | | | | | | | | | | | | | | | 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 Viehland2024-04-191-0/+1
| | | | | | | (#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-117613: Argument Clinic: disallow defining class parameter at module ↵neonene2024-04-171-0/+2

* gh-117657: Quiet erroneous TSAN reports of data races in `_PySeqLock` (#117955)mpage2024-04-171-2/+0
| | | | | | | | Quiet erroneous TSAN reports of data races in `_PySeqLock` TSAN reports a couple of data races between the compare/exchange in `_PySeqLock_LockWrite` and the non-atomic loads in `_PySeqLock_{Abandon,Unlock}Write`. This is another instance of TSAN incorrectly modeling failed compare/exchange as a write instead of a load.
* gh-117657: Fix data races in the method cache in free-threaded builds (#117954)mpage2024-04-171-1/+0
| | | | | | | | | Fix data races in the method cache in free-threaded builds These are technically data races, but I think they're benign (to the extent that that is actually possible). We update cache entries non-atomically but read them atomically from another thread, and there's nothing that establishes a happens-before relationship between the reads and writes that I can see.

* gh-116968: Reimplement Tier 2 counters (#117144)Guido van Rossum2024-04-041-0/+1
| | | | | | | | | | | | 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.
