In D92191, a bunch of test cases were added to check clang-scan-deps works in clang-cl mode as well.
We don't need to duplicate all test cases, though. Testing the few special cases we have in clang-scan-deps for clang-cl should be good enough:
- Deducing output path (and therefore target name in our make output).
- Ignoring -Xclang arguments in step 1.
- Deducing resource directory by invoking the compiler executuable.
This test de-duplicates the extra clang-cl test cases.
