* gh-99254: remove all unused consts from code objects (GH-99255)Irit Katriel2022-11-111-11/+11
|
* GH-98686: Get rid of "adaptive" and "quick" instructions (GH-99182)Brandt Bucher2022-11-091-2/+2
|
* GH-96793: Implement PEP 479 in bytecode. (GH-99006)Mark Shannon2022-11-031-1/+3
| | | | | * Handle converting StopIteration to RuntimeError in bytecode. * Add custom instruction for converting StopIteration into RuntimeError.

* GH-96793: Change `FOR_ITER` to not pop the iterator on exhaustion. (GH-96801)Mark Shannon2022-10-271-92/+96
| | | | 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-92886: make test_ast pass with -O (assertions off) (GH-98058)Irit Katriel2022-10-071-1/+1
| | | | | -O does not strip docstrings. Automerge-Triggered-By: GH:iritkatriel

* GH-95113: Don't use EXTENDED_ARG_QUICK in unquickened code (GH-95121)Brandt Bucher2022-07-221-1/+1
|
* gh-92228: disable the compiler's 'small exit block inlining' optimization ↵Irit Katriel2022-07-071-20/+7
| | | | | | | for blocks that have a line number (GH-94592) Inlining of code that corresponds to source code lines, can make it hard to distinguish later between code which is only reachable from except handlers, and that which is reachable in normal control flow. This caused problems with the debugger's jump feature. This PR turns off the inlining optimisation for code which has line numbers. We still inline things like the implicit "return None".
* gh-94485: Set line number of module's RESUME instruction to 0, as specified ↵Irit Katriel2022-07-051-9/+9
