URL: https://github.com/llvm/llvm-project/commit/ca6d5813d17598cd180995fb3bdfca00f364475f DIFF: https://github.com/llvm/llvm-project/commit/ca6d5813d17598cd180995fb3bdfca00f364475f.diff LOG: [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.
