class LPPassManager
Declaration
class LPPassManager : public FunctionPass, public PMDataManager { /* full declaration omitted */ };Description
FunctionPass class - This class is used to implement most global optimizations. Optimizations should subclass this class if they meet the following constraints: 1. Optimizations are organized globally, i.e., a function at a time 2. Optimizing a function does not cause the addition or removal of any functions in the module

¶llvm::StringRef getPassName() const
llvm::StringRef getPassName() constDescription
getPassName - Return a nice clean name for a pass. This usually implemented in terms of the name that is registered by one of the Registration templates, but can be overloaded directly.

¶bool runOnFunction(llvm::Function& F)
bool runOnFunction(llvm::Function& F)Description
run - Execute all of the passes scheduled for execution. Keep track of whether any of the passes modifies the module, and if so, return true.
