It might be better if we offered this as an option to turn off and on through configure (My personal fork of the JDK has something along the lines of --enable-linktime-opt, can't remember the exact name) rather than making some native code have to use LTO. Additionally I also think this is better done similar to how HotSpot does it instead of adding LTO options as an exported Makefile variable and adding a new parameter to SetupNativeCompilation. ------------- PR Comment: https://git.openjdk.org/jdk/pull/27976#issuecomment-3443306972
