Hi, I have a new variant of Aggressive Dead Code Elimination that also removes dead branching. It is designed to minimize the cost of control-dependence analysis in the common case where almost the entire program is live. It also can optionally remove dead but may-be-infinite loops. When enabled for –O3 (replacing current ADCE pass) and removing loops, impact on SPEC2006 is in the noise but it

Thanks for the response. To clarify in your suggestion, llvm-link will combine the modules but not run the optimization pass, that is still delayed until the final binary is built, correct? My use case is apply LTO to roughly program subsets; sacrificing effectiveness to avoid scaling problems and to allow the artifacts to be reused like archives and cached like .o’s. I need to trigger the
