The majority of the functions that are eliminated are small functions, for those the extra overhead due to inefficiencies in gimplification is significant. Maybe the people interested in compilation speed at -O0 (especially for C++) want to take a look at this and the related PRs... -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27810
