--- Comment #17 from Jeffrey A. Law <law at redhat dot com> --- Dominique, thanks for verifying that 58746 is a duplicate. I was wondering about that. Richi, we've known for a long time (since the early 90s) that running CSE soon after loop unrolling is profitable. Soooo, why not run conditionally run DOM after unrolling? That wouldn't create a compile-time hit for a typical -O2 compilation.
