| Apply a patch from pixman upstream to fix the follwing build error with clang: |
| pixman-mmx.c:100:20: error: constraint 'K' expects an integer constant expression |
| : "y" (__A), "K" (__N) |
| |
| The error happens because __N is a function parameter and clang does not |
| process it as an integer literal by design. |
| Fix this by forcing the macro version of the function which exposes __N value |
| as an integer literal. https://crbug.com/793487 |
