* GH-131238: More refactoring of core header files (GH-131351)Mark Shannon2025-03-17
| | | | Adds new pycore_stats.h header file to help break dependencies involving the pycore_code.h header.
* gh-130480: Move duplicate `LOAD_SMALL_INT` optimization from codegen to CFG ↵Yan Yanchii2025-03-14

| | | | the pattern. (GH-130627)
* GH-128534: Fix behavior of branch monitoring for `async for` (GH-130847)Mark Shannon2025-03-07
| | | * Both branches in a pair now have a common source and are included in co_branches
* gh-130740: Move some `stdbool.h` includes after `Python.h` (#130738)Hugo Beauzée-Luyssen2025-03-02
| | | | | Move some `#include <stdbool.h>` after `#include "Python.h"` when `pyconfig.h` is not included first and when we are in a platform-agnostic context. This is to avoid having features defined by `stdbool.h` before those decided by `Python.h`.
* GH-128534: Instrument branches for `async for` loops. (GH-130569)Mark Shannon2025-02-27
|
* GH-130396: Use computed stack limits on linux (GH-130398)Mark Shannon2025-02-25
| | | | | | | | | | | * Implement C recursion protection with limit pointers for Linux, MacOS and Windows * Remove calls to PyOS_CheckStack * Add stack protection to parser * Make tests more robust to low stacks * Improve error messages for stack overflow
* gh-100239: replace BINARY_SUBSCR & family by BINARY_OP with oparg NB_SUBSCR ↵Irit Katriel2025-02-07
| | | | (#129700)
* gh-126835: Move constant subscript folding to CFG (#129568)Yan Yanchii2025-02-04
| | | | | Move folding of constant subscription from AST optimizer to CFG. Co-authored-by: Irit Katriel <1055913+iritkatriel@users.noreply.github.com>

| | | | | | | | | | | | | | | | | | | | | | CFG (#129426) Codegen phase has an optimization that transforms ``` LOAD_CONST x LOAD_CONST y LOAD_CONXT z BUILD_LIST/BUILD_SET (3) ``` -> ``` BUILD_LIST/BUILD_SET (0) LOAD_CONST (x, y, z) LIST_EXTEND/SET_UPDATE 1 ``` This optimization has now been moved to CFG phase to make #128802 work.

| | | | | | | | | | | | | * Remove all 'if (0)' and 'if (1)' conditional stack effects * Use array instead of conditional for BUILD_SLICE args * Refactor LOAD_GLOBAL to use a common conditional uop * Remove conditional stack effects from LOAD_ATTR specializations * Replace conditional stack effects in LOAD_ATTR with a 0 or 1 sized array. * Remove conditional stack effects from CALL_FUNCTION_EX
