The test was failing on Windows machines which had bash.exe on PATH (but not in the so called lit tools dir, containing cmp.exe, grep.exe etc.). The problem was that the outer lit invocation would load LLVMConfig from utils/lit/lit/llvm/config.py, which looks up the tools path with getToolsPath(). That has a surprising side effect of also setting bashPath, in our case setting it to empty. The outer lit invocation would thus configure the pdbg0 and pdbg1 substitutions based on not running with bash. But the inner lit invocation would not load LLVMConfig, so bash would be found on PATH, that would be used as external shell, and so the output wouldn't match pdbg0 and pdbg1. It seems weird to me that getBashPath() will return different results depending on whether getToolsPath() has been called before, but I also don't know how to fix it properly. This commit just relaxes the test case, because there doesn't seem to be much point in testing for the exact syntax of the run file as long as it works.

===============================
lit - A Software Testing Tool
===============================
lit is a portable tool for executing LLVM and Clang style test suites,
summarizing their results, and providing indication of failures. lit is designed
to be a lightweight testing tool with as simple a user interface as possible.
=====================
Contributing to lit
=====================
Please browse the Test Suite > lit category in LLVM's Bugzilla for ideas on
what to work on.
Before submitting patches, run the test suite to ensure nothing has regressed:
# From within your LLVM source directory.
utils/lit/lit.py \
--path /path/to/your/llvm/build/bin \
utils/lit/tests
Note that lit's tests depend on 'not' and 'FileCheck', LLVM utilities.
You will need to have built LLVM tools in order to run lit's test suite
successfully.
You'll also want to confirm that lit continues to work when testing LLVM.
Follow the instructions in http://llvm.org/docs/TestingGuide.html to run the
regression test suite:
make check-llvm
And be sure to run the llvm-lit wrapper script as well:
/path/to/your/llvm/build/bin/llvm-lit utils/lit/tests
Finally, make sure lit works when installed via setuptools:
python utils/lit/setup.py install
lit --path /path/to/your/llvm/build/bin utils/lit/tests
