|
* GH-112354: `END_FOR` instruction to only pop one value. (GH-114247)Mark Shannon2024-01-241-12/+12
| | | | * Compiler emits END_FOR; POP_TOP instead of END_FOR. To support tier 2 side exits in loops.

* GH-113689: Fix broken handling of invalid executors (GH-113694)Brandt Bucher2024-01-041-1/+2
|
* GH-113595: Don't enter invalid executor (GH-113596)Mark Shannon2024-01-031-9/+19
|
* gh-111375: Use `NULL` rather than `None` in the exception stack to indicate ↵Carey Metcalfe2023-12-211-1/+1
| | | | that an exception was handled (#113302)

| | | | instructions in bytecodes.c (#112520)
* Rename ...Uop... to ...UOp... (uppercase O) for consistency (#112327)Guido van Rossum2023-11-291-1/+1
| | | | * Rename _PyUopExecute to _PyUOpExecute (uppercase O) for consistency * Also rename _PyUopName and _PyUOp_Replacements, and some output strings
* 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/

* GH-111485: Silence warnings in Python/executor_cases.c.h (#111619)Guido van Rossum2023-11-011-0/+2

* gh-111520: Integrate the Tier 2 interpreter in the Tier 1 interpreter (#111428)Guido van Rossum2023-11-011-62/+64
| | | | | | | | | | | - 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`.

* gh-109979: Unify _GUARD_TYPE_VERSION{,_STORE} (#110301)Guido van Rossum2023-10-031-8/+2
| | | | | Now the target for `DEOPT_IF()` is auto-filled, we don't need a separate `_GUARD_TYPE_VERSION_STORE` uop.
* gh-109979: Auto-generate the target for DEOPT_IF() (#110193)Guido van Rossum2023-10-031-183/+169
| | | | | | | | | | | | | | | | In Python/bytecodes.c, you now write ``` DEOPT_IF(condition); ``` The code generator expands this to ``` DEOPT_IF(condition, opcode); ``` where `opcode` is the name of the unspecialized instruction. This works inside macro expansions too. **CAVEAT:** The entire `DEOPT_IF(condition)` statement must be on a single line. If it isn't, the substitution will fail; an error will be printed by the code generator and the C compiler will report some errors.
