After we removed mapfiles, we can setup -fvisibility=hidden (and -Wl,--exclude-libs,ALL) in the most basic flags, so this applies to all compilation.
This will remove duplicate code and make the underlying assumptions of the build clearer. (This PR replaces https://github.com/openjdk/jdk/pull/18061 which got too messy.) ------------- Commit messages: - 8327045: Consolidate -fvisibility=hidden as a basic flag for all compilation Changes: https://git.openjdk.org/jdk/pull/18267/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=18267&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8327045 Stats: 46 lines in 6 files changed: 4 ins; 37 del; 5 mod Patch: https://git.openjdk.org/jdk/pull/18267.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/18267/head:pull/18267 PR: https://git.openjdk.org/jdk/pull/18267
