* GH-120507: Lower the `BEFORE_WITH` and `BEFORE_ASYNC_WITH` instructions. ↵Mark Shannon2024-06-181-184/+202
| | | | | | | | | (#120640) * Remove BEFORE_WITH and BEFORE_ASYNC_WITH instructions. * Add LOAD_SPECIAL instruction * Reimplement `with` and `async with` statements using LOAD_SPECIAL

* gh-119180: Add LOAD_COMMON_CONSTANT opcode (#119321)Jelle Zijlstra2024-05-221-117/+117
| | | | | | | | | | 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-109039: Branch prediction for Tier 2 interpreter (#109038)Guido van Rossum2023-09-111-109/+113
| | | | | | | | | | | 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.
