As I wrote these are optional (different issues, quite useful to have but still easy to work around with different means), the main issue is still missing NOINLINE for -flto. > More importantly what is the effect of NOINLINE if a user > does not specify the -flto option?

As long as subroutines/functions are in separate compilation units, this has no effect for non-LTO builds anyway. Main issue is to deal with unintentional over inlining between different compilation units with lto1 backend. Best regards, Rimvydas
