+"""
+This script generates multi-threaded tests to check free-threading mode.
+Tests can be run using pytest:
+```bash
+python3.13t -mpytest -vvv multithreaded_tests.py
+```
+
+1) Multi-threaded execution: all generated tests are executed independently by
+a pool of threads, running each test multiple times, see @multi_threaded for details
+
+2) Tests generation: we use existing tests: test/python/ir/*.py,
+test/python/dialects/*.py, etc to generate multi-threaded tests.
+In details, we perform the following:
+a) we define a list of source tests to be used to generate multi-threaded tests, see `test_modules`.
+b) we define `TestAllMultiThreaded` class and add existing tests to the class. See `add_existing_tests` method.
+c) for each test file, we copy and modify it: test/python/ir/affine_expr.py -> /tmp/ir/affine_expr.py.
+In order to import the test file as python module, we remove all executing functions, like
+`@run` or `run(testMethod)`. See `copy_and_update` and `add_existing_tests` methods for details.
