Yes, I checked those. The tool is a fool. There are other cases like softfloat functions and TCG runtime parts which may be unused for some host/target combinations. In theory, with lots of #ifdeffery or splitting the files into smaller pieces, the unused parts could be disabled, but that would be silly. A better approach might be using some kind of AR library but it would still be a lot of effort for little gain. > > [..snip..] > > -- > mailto:av1...@comtv.ru
