Currently, we issue -Wno-unused for all files in clang, which is a rather big sledgehammer to get rid of some warnings that proliferate in a few areas of the build.
We should instead leave -Wunused turned on (as done by -Wall) and use a much more fine-grained approach to disabling specific warnings in specific files or libraries. This is similar to what has been done for gcc in JDK-8339120. ------------- Commit messages: - 8339156: Use more fine-granular clang unused warnings Changes: https://git.openjdk.org/jdk/pull/20770/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=20770&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8339156 Stats: 60 lines in 16 files changed: 42 ins; 1 del; 17 mod Patch: https://git.openjdk.org/jdk/pull/20770.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/20770/head:pull/20770 PR: https://git.openjdk.org/jdk/pull/20770
