| 8 | commit bb3f38c3c5b759163e09b9152629cc789731de47 upstream. | |
| 9 | ||
| 10 | We should avoid using the space character when passing arguments to | |
| 11 | clang, because static code analysis check tool such as sparse may | |
| 12 | misinterpret the arguments followed by spaces as build targets hence | |
| 13 | cause the build to fail. | |
