<p class="MsoNormal">When do you want it to run? Machine specific passes are invoked during codegen. It looks like anything you add via addPreEmitPass should get invoked during LTO codegen (via TargetMachine::addPassesToEmitFile which eventually calls that
through some other layers). Are you sure it isn't being invoked during LTO codegen? <o:p></o:p></p>
