* gh-130907: Treat all module-level annotations as conditional (#131550)Jelle Zijlstra2025-04-281-10/+11

* gh-130704: Strength reduce `LOAD_FAST{_LOAD_FAST}` (#130708)mpage2025-04-011-33/+35
| | | Optimize `LOAD_FAST` opcodes into faster versions that load borrowed references onto the operand stack when we can prove that the lifetime of the local outlives the lifetime of the temporary that is loaded onto the stack.

| | | | | | | the code generators (GH-128918)" (GH-129202) The commit introduced a ~2.5-3% regression in the free threading build. This reverts commit ab61d3f4303d14a413bc9ae6557c730ffdf7579e.

| | | | | | | * Spill the evaluation around escaping calls in the generated interpreter and JIT. * The code generator tracks live, cached values so they can be saved to memory when needed. * Spills the stack pointer around escaping calls, so that the exact stack is visible to the cycle GC.

* gh-119180: Add LOAD_COMMON_CONSTANT opcode (#119321)Jelle Zijlstra2024-05-221-61/+61
| | | | | | | | | | The PEP 649 implementation will require a way to load NotImplementedError from the bytecode. @markshannon suggested implementing this by converting LOAD_ASSERTION_ERROR into a more general mechanism for loading constants. This PR adds this new opcode. I will work on the rest of the implementation of the PEP separately. Co-authored-by: Irit Katriel <1055913+iritkatriel@users.noreply.github.com>

| | | | | | | | | | support of calls. (GH-118322) * Add CALL_PY_GENERAL, CALL_BOUND_METHOD_GENERAL and call CALL_NON_PY_GENERAL specializations. * Remove CALL_PY_WITH_DEFAULTS specialization * Use CALL_NON_PY_GENERAL in more cases when otherwise failing to specialize
