      The dead_strip linker option on macOS removes functions and data that are unreachable by the entry point or exported symbols.
      Setting it can reduce the size of some binaries we generate quite a lot, for example (product build, Xcode 15 is used) :
      (before -> after setting the option)
      1.4M -> 1.1M images/jdk/lib/libfontmanager.dylib
      264K -> 248K images/jdk/lib/libjavajpeg.dylib
      152K -> 132K images/jdk/lib/libjli.dylib
      388K -> 296K images/jdk/lib/liblcms.dylib
      164K -> 128K images/jdk/lib/libzip.dylib

      and libjvm :
      20M -> 18M images/jdk/lib/server/libjvm.dylib
      146M -> 137M images/jdk/lib/server/libjvm.dylib.dSYM
