* gh-109039: Branch prediction for Tier 2 interpreter (#109038)Guido van Rossum2023-09-111-0/+12
| | | | | | | | | | | 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.

| | | | | | | | | | | | | | This implements PEP 695, Type Parameter Syntax. It adds support for: - Generic functions (def func[T](): ...) - Generic classes (class X[T](): ...) - Type aliases (type X = ...) - New scoping when the new syntax is used within a class body - Compiler and interpreter changes to support the new syntax and scoping rules Co-authored-by: Marc Mueller <30130371+cdce8p@users.noreply.github.com> Co-authored-by: Eric Traut <eric@traut.com> Co-authored-by: Larry Hastings <larry@hastings.org> Co-authored-by: Alex Waygood <Alex.Waygood@Gmail.com>
