Having the original output directly from the toolchain be more compact is also desireable, but it is not our near-term focus. This work I'm talking about will address size concerns. The quality/usefulness of the info is another matter, which certainly does entail compiler work. There are some long-term efforts going in that area, but that is a separate issue from what I'm doing now. Thanks, Roland
