<pre>
We want to generate coverage report using `llvm-show` only for given directories. llvm-cov has the flag `--ignore-filename-regex=` to ignore source files that matches the regex, but it doesn't support negative lookahead (e.g. we only want coverage report for source files recursively inside folder1 `(?!folder1)`).
I think we should add a flag for this unless there is another way to solve it.
