Subject: Don't #include heavy Dominators.h file in LoopInfo.h. This change reduces
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=7ae72bfd9470e5f91e43652cafe15e0c56b4b3d1;p=oota-llvm.git

Don't #include heavy Dominators.h file in LoopInfo.h. This change reduces
overall time of LLVM compilation by ~1%.
