| Subject: [PATCH] [clang] Do not warn unused |
| -enable-trivial-auto-var-init-zero-knowing-it-will-be-removed-from-clang |
| |
| Android enables zero initialisation globally by default, but also allows |
| subprojects to override with different option. Clang complains the above |
| flag being unused in this case. |
| |
| Instead of adding a 75 char long -no-* flag, don't warn unused argument |
| for this flag. |
