@TheShermanTanker , @magicus  what do you think ? Should we additionally offer  LTO on library level ?
See
https://github.com/openjdk/jdk/blob/master/make/common/native/Flags.gmk#L43

Currently we only have it as an additional option for libjvm and not the other native libs .

Yes true for libjvm this is possible, it is the opt-size  part of the minimal features set
`JVM_FEATURES_minimal='compiler1 minimal opt-size serialgc'`
