As an alternative to using a compilation database, you could also use 
the `--` flag. Suppose your normal clang command-line was:

   $ clang -fblocks foo.c

Then your clang-tidy command-line would be something like:

   $ clang-tidy foo.c -checks=* -- -fblocks foo.c

Where the set of arguments that go after the `--` is just the same set 
you would have normally passed to clang.
