[PATCH] D81361: Make lit TestRunner.py work in Python 3

[Tim Kientzle via Phabricator via llvm-commits]

tbkka added a comment.

Here are some more details:

Swift's lit.cfg wraps certain substitutions in a class that is part of LLVM's lit implementation (specifically `class SubstituteCaptures` from `TestingConfig.py`).  This class breaks the logic in `TestRunner.py` on Python3:  Python 2.7's regex always stringified its arguments implicitly; Python3 does not.  Apparently, the `SubstituteCaptures` class is not currently used anywhere in LLVM itself, which is why this mismatch isn't breaking LLVM builds.
