Subject: SSI needs to require DT and DF transitively, since it uses them outside of its runOnF... 
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=7aa3c781b4e3acadcdd7094deed14aa2e76ab625;p=oota-llvm.git

SSI needs to require DT and DF transitively, since it uses them outside of its runOnFunction.
Similarly, it can be marked setPreservesAll, since it does no work in its runOnFunction.
