* GH-115651: Convert `LOAD_MODULE_ATTR` into `LOAD_INLINE_CONST` when the ↵Mark Shannon2024-02-221-2/+2

* gh-112175: Add `eval_breaker` to `PyThreadState` (#115194)Brett Simmers2024-02-201-4/+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.

* gh-106529: Make FOR_ITER a viable uop (#112134)Guido van Rossum2023-11-201-2/+21
| | | | | | | | | | This uses the new mechanism whereby certain uops are replaced by others during translation, using the `_PyUop_Replacements` table. We further special-case the `_FOR_ITER_TIER_TWO` uop to update the deoptimization target to point just past the corresponding `END_FOR` opcode. Two tiny code cleanups are also part of this PR.
* gh-110319: Assert type_version != 0 before using it (#112226)Guido van Rossum2023-11-181-2/+2
| | | | | | - Ensure that `assert(type_version != 0);` always comes *before* using `type_version` Also: - In cases_generator, rename `-v` to from `--verbose` to `--viable`
* gh-106529: Cleanups split off gh-112134 (#112214)Guido van Rossum2023-11-171-0/+1
| | | | | | | - Double max trace size to 256 - Add a dependency on executor_cases.c.h for ceval.o - Mark `_SPECIALIZE_UNPACK_SEQUENCE` as `TIER_ONE_ONLY` - Add debug output back showing the optimized trace - Bunch of cleanups to Tools/cases_generator/

| | | | | | | | | | | - There is no longer a separate Python/executor.c file. - Conventions in Python/bytecodes.c are slightly different -- don't use `goto error`, you must use `GOTO_ERROR(error)` (same for others like `unused_local_error`). - The `TIER_ONE` and `TIER_TWO` symbols are only valid in the generated (.c.h) files. - In Lib/test/support/__init__.py, `Py_C_RECURSION_LIMIT` is imported from `_testcapi`. - On Windows, in debug mode, stack allocation grows from 8MiB to 12MiB. - **Beware!** This changes the env vars to enable uops and their debugging to `PYTHON_UOPS` and `PYTHON_LLTRACE`.
