[cfe-dev] run integration tests for single file

[Alexander Droste]

Hi,

thanks for your reply.
I have positioned the test file in llvm/tools/clang/test/Analysis
which includes a lot of other regression test files.
For each other file I tried, the llvm-lit command works.
A lit config file is contained in that folder.
I think the question is how the lit configuration can be
regenerated/configured to fix the issue.

Best regards,
Alex
