MaskRay added a comment.
The code change looks good but the driver test will cause an issue.
I think we need a fake sysroot tree under `Inputs/`.
Otherwise if we have a system cross gcc at
`/usr/lib/gcc{,-cross}/powerpc64le-unknown-eabi/12`, Clang Driver will pick up
these files.
This is really difficult to debug for someone not so familiar with Driver (I
think I have done quite a lot of work, but still quite puzzled).
You may check many other tests using --sysroot, remove --sysroot, and check the
behavior change.
