--- Comment #6 from Marc Glisse <glisse at gcc dot gnu.org> --- (In reply to Peter Bergner from comment #5) > Why do we have to special case these functions? Why can't we do this for > all functions that are marked as const/pure, since we know they have no side > effects other than their return value? * I expect we already optimize pure/const functions. Do you have an example where we don't? * malloc, strdup, etc are not pure!
