* gh-112175: Add `eval_breaker` to `PyThreadState` (#115194)Brett Simmers2024-02-201-1/+1
| | | | | | | | | | | 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-112287: Speed up Tier 2 (uop) interpreter a little (#112286)Guido van Rossum2023-11-201-22/+113
| | | | | | | | | | | | | | | | | | | | | | | | | | This makes the Tier 2 interpreter a little faster. I calculated by about 3%, though I hesitate to claim an exact number. This starts by doubling the trace size limit (to 512), making it more likely that loops fit in a trace. The rest of the approach is to only load `oparg` and `operand` in cases that use them. The code generator know when these are used. For `oparg`, it will conditionally emit ``` oparg = CURRENT_OPARG(); ``` at the top of the case block. (The `oparg` variable may be referenced multiple times by the instructions code block, so it must be in a variable.) For `operand`, it will use `CURRENT_OPERAND()` directly instead of referencing the `operand` variable, which no longer exists. (There is only one place where this will be used.)
* gh-106529: Make FOR_ITER a viable uop (#112134)Guido van Rossum2023-11-201-0/+25
| | | | | | | | | | 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.

| | | | | | | | | | | - 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`.
