* GH-120507: Lower the `BEFORE_WITH` and `BEFORE_ASYNC_WITH` instructions. ↵Mark Shannon2024-06-18
| | | | | | | | | (#120640) * Remove BEFORE_WITH and BEFORE_ASYNC_WITH instructions. * Add LOAD_SPECIAL instruction * Reimplement `with` and `async with` statements using LOAD_SPECIAL
* gh-119311: Fix name mangling with PEP 695 generic classes (#119464)Jelle Zijlstra2024-05-27
| | | | Fixes #119311. Fixes #119395.
* gh-119180: Update the magic number (#119397)Jelle Zijlstra2024-05-24
| | | | PR #119321 added a comment about the magic number bump but did not actually apply the new magic number.
* gh-119180: Add LOAD_COMMON_CONSTANT opcode (#119321)Jelle Zijlstra2024-05-22
| | | | | | | | | | 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>

* gh-89739: gh-77140: Support zip64 in zipimport (GH-94146)Tim Hatch2024-03-28
| | | | | | | | | | | | | | | * Reads zip64 files as produced by the zipfile module * Include tests (somewhat slow, however, because of the need to create "large" zips) * About the same amount of strictness reading invalid zip files as zipfile has * Still works on files with prepended data (like pex) There are a lot more test cases at https://github.com/thatch/zipimport64/ that give me confidence that this works for real-world files. Fixes #89739 and #77140. --------- Co-authored-by: Itamar Ostricher <itamarost@gmail.com> Reviewed-by: Gregory P. Smith <greg@krypto.org>

* gh-109039: Branch prediction for Tier 2 interpreter (#109038)Guido van Rossum2023-09-11
| | | | | | | | | | | This adds a 16-bit inline cache entry to the conditional branch instructions POP_JUMP_IF_{FALSE,TRUE,NONE,NOT_NONE} and their instrumented variants, which is used to keep track of the branch direction. Each time we encounter these instructions we shift the cache entry left by one and set the bottom bit to whether we jumped. Then when it's time to translate such a branch to Tier 2 uops, we use the bit count from the cache entry to decided whether to continue translating the "didn't jump" branch or the "jumped" branch. The counter is initialized to a pattern of alternating ones and zeros to avoid bias. The .pyc file magic number is updated. There's a new test, some fixes for existing tests, and a few miscellaneous cleanups.
