0 uudruid74 Posted April 15, 2015 Report Share Posted April 15, 2015 Gcc supports a "native" target where it detects what cpu its running on and then uses that for almost code generation options. Unless you build on a host that is different from the target, why not use this feature? Link to comment Share on other sites More sharing options...
