Currently, we issue -Wno-unused for all files in gcc, 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. ------------- Commit messages: - Fix debug builds - Try fixing static builds on zero - Fix zero - Fix libfallbackLinker - Also update native tests - 8339120: Use more fine-granular gcc unused warnings Changes: https://git.openjdk.org/jdk/pull/20733/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=20733&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8339120 Stats: 50 lines in 17 files changed: 28 ins; 0 del; 22 mod Patch: https://git.openjdk.org/jdk/pull/20733.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/20733/head:pull/20733 PR: https://git.openjdk.org/jdk/pull/20733
