[llvm-dev] Target Specific LTO Machine Pass

[Teresa Johnson via llvm-dev]

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?
