Subject: licm preserves the cfg, it doesn't have to explicitly say it
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=e418ac832c1a2813736c44f6ec5c646b4c89c339;p=oota-llvm.git

licm preserves the cfg, it doesn't have to explicitly say it
preserves domfrontier.  It does preserve AA though.
