Silenced some VC warnings. I'm getting linker errors, though: unresolved externals: llvm::Split<class llvm::BasicBlock *,struct llvm::GraphTraits<class llvm::BasicBlock *> >(class llvm::DominatorTreeBase<class llvm::BasicBlock> &,class llvm::BasicBlock *) and llvm::Split<struct llvm::Inverse<class llvm::BasicBlock *>,struct llvm::GraphTraits<struct llvm::Inverse<class llvm::BasicBlock *> > >(class llvm::DominatorTreeBase<class llvm::BasicBlock> &,class llvm::BasicBlock *) Where are these defined? git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43073 91177308-0d34-0410-b5e6-96231b3b80d8
