|
* gh-105775: Convert LOAD_CLOSURE to a pseudo-op (#106059)hms2023-06-29
| | | | | | This enables super-instruction formation, removal of checks for uninitialized variables, and frees up an instruction.

* gh-103865: add monitoring support to LOAD_SUPER_ATTR (#103866)Carl Meyer2023-05-16
|
* gh-103763: Implement PEP 695 (#103764)Jelle Zijlstra2023-05-15
| | | | | | | | | | | | | | This implements PEP 695, Type Parameter Syntax. It adds support for: - Generic functions (def func[T](): ...) - Generic classes (class X[T](): ...) - Type aliases (type X = ...) - New scoping when the new syntax is used within a class body - Compiler and interpreter changes to support the new syntax and scoping rules Co-authored-by: Marc Mueller <30130371+cdce8p@users.noreply.github.com> Co-authored-by: Eric Traut <eric@traut.com> Co-authored-by: Larry Hastings <larry@hastings.org> Co-authored-by: Alex Waygood <Alex.Waygood@Gmail.com>

|
* gh-97933: (PEP 709) inline list/dict/set comprehensions (#101441)Carl Meyer2023-05-09
| | | | Co-authored-by: Irit Katriel <1055913+iritkatriel@users.noreply.github.com> Co-authored-by: Erlend E. Aasland <erlend.aasland@protonmail.com>
* gh-87729: specialize LOAD_SUPER_ATTR_METHOD (#103809)Carl Meyer2023-04-25
|
* gh-87729: add LOAD_SUPER_ATTR instruction for faster super() (#103497)Carl Meyer2023-04-24
| | | | | This speeds up `super()` (by around 85%, for a simple one-level `super().meth()` microbenchmark) by avoiding allocation of a new single-use `super()` object on each use.
* GH-103082: Implementation of PEP 669: Low Impact Monitoring for CPython ↵Mark Shannon2023-04-12
| | | | | | | | | | (GH-103083) * The majority of the monitoring code is in instrumentation.c * The new instrumentation bytecodes are in bytecodes.c * legacy_tracing.c adapts the new API to the old sys.setrace and sys.setprofile APIs

* GH-99005: Add `CALL_INTRINSIC_1` instruction (GH-100771)Mark Shannon2023-01-05
| | | | | | | | * Remove PRINT_EXPR instruction * Remove STOPITERATION_ERROR instruction * Remove IMPORT_STAR instruction

* Revert "gh-100288: Specialise LOAD_ATTR_METHOD for managed dictionaries ↵Ken Jin2022-12-24
| | | | | (GH-100289)" (#100468) This reverts commit c3c7848a48b74a321632202e4bdcf2f465fb1cc6.

|
* GH-96421: Insert shim frame on entry to interpreter (GH-96319)Mark Shannon2022-11-10
| | | | | | * Adds EXIT_INTERPRETER instruction to exit PyEval_EvalDefault() * Simplifies RETURN_VALUE, YIELD_VALUE and RETURN_GENERATOR instructions as they no longer need to check for entry frames.
* GH-98686: Get rid of "adaptive" and "quick" instructions (GH-99182)Brandt Bucher2022-11-09
|
* GH-96793: Specialize FOR_ITER for generators. (GH-98772)Mark Shannon2022-11-07
|
* GH-96793: Implement PEP 479 in bytecode. (GH-99006)Mark Shannon2022-11-03

|
* GH-96793: Change `FOR_ITER` to not pop the iterator on exhaustion. (GH-96801)Mark Shannon2022-10-27
| | | | Change FOR_ITER to have the same stack effect regardless of whether it branches or not. Performance is unchanged as FOR_ITER (and specialized forms jump over the cleanup code).
* gh-97669: Create Tools/build/ directory (#97963)Victor Stinner2022-10-17
| | | | | | | | | | | | | | | | | | | | | | | Create Tools/build/ directory.
