◆ runOnModule()
runOnModule - Virtual method overriden by subclasses to process the module being operated on.
Implemented in llvm::FPPassManager, llvm::CallGraphWrapperPass, llvm::ImmutablePass, llvm::DOTGraphTraitsModulePrinter< AnalysisT, IsSimple, GraphT, AnalysisGraphTraitsT >, llvm::GlobalsAAWrapperPass, llvm::DOTGraphTraitsModuleViewer< AnalysisT, IsSimple, GraphT, AnalysisGraphTraitsT >, llvm::StackSafetyGlobalInfoWrapperPass, and llvm::ModuleSummaryIndexWrapperPass.
