- In Python 2.x, basestring is the base string type, but in Python 3.x basestring is not defined and instead str includes unicode strings. - When Python is in a path that includes spaces, it needs to be specified with quotes in the test files for it to run. - The cache.ll test relies on files of a specific size being created by Python, but on some versions of Windows the files that are created by the current code are one byte larger than expected. To fix the test, update file creation to always make files of the expected size. Patch by Stella Stamenova! llvm-svn: 329466
