For the free-threaded version of the cyclic GC, restructure the "mark alive" phase to use software prefetch instructions. This gives a speedup in most cases when the number of objects is large enough. The prefetching is enabled conditionally based on the number of long-lived objects the GC finds.
As a first step toward aligning the grammar documentation with Python's actual
grammar, this overrides the ReST `productionlist` directive to:
- use `:` instead of the `::=` symbol
- add syntax highlighting for strings (using a Pygments highlighting class)
All links and link targets should be preserved. (Unfortunately, this reaches
into some Sphinx internals; I don't see a better way to do exactly what
Sphinx does.)
This also adds a new directive, `grammar-snippet`, which formats the snippet
almost exactly like what's in the source, modulo syntax highlighting and
keeping the backtick character to mark links to other rules.
This will allow formatting the snippets as in the grammar file
(file:///home/encukou/dev/cpython/Doc/build/html/reference/grammar.html).
The new directive is applied to two simple rules in toplevel_components.rst

This adds a new command line argument, `--parallel-threads` to the
regression test runner to allow it to run individual tests in multiple
threads in parallel in order to find multithreading bugs.
Some tests pass when run with `--parallel-threads`, but there's still
more work before the entire suite passes.
Test that the trailing pathname separator is preserved.
Multiple trailing pathname separators are only preserved if the pattern
does not contain metacharacters, otherwise only one trailing pathname
separator is preserved. This is rather an implementation detail.
The ``fintl`` module is never installed or tested, meaning that the
fallback identity function is unconditionally used for ``_()``.
This means we can simplify, converting the docstring to a real
docstring, and converting some other strings to f-strings.
We also convert the module to UTF-8, sort imports,
and remove the history comment, which was last updated in 2002.
Consult the git history for a more accurate summary of changes.
Restore the skipUnless removed by #119465.
This test can only pass on virtual machines, not actual machines.
actual machines see:
```
self.cli.connect((cid, VSOCKPORT))
~~~~~~~~~~~~~~~~^^^^^^^^^^^^^^^^^^
OSError: [Errno 19] No such device
```
Reproduced on (Linux) Ubuntu 24.04.1 running 6.8.0-52-generic.
Move many functions from _testcapimodule.c into more specific files
in Modules/_testcapi/.
In moved code:
* Replace get_testerror() with PyExc_AssertionError.
* Replace raiseTestError() with
PyErr_Format(PyExc_AssertionError, ...).
Codegen phase has an optimization that transforms
```
LOAD_CONST x
LOAD_CONST y
LOAD_CONXT z
BUILD_LIST/BUILD_SET (3)
```
->
```
BUILD_LIST/BUILD_SET (0)
LOAD_CONST (x, y, z)
LIST_EXTEND/SET_UPDATE 1
```
This optimization has now been moved to CFG phase to make #128802 work.
