Represent the analysis usage information of a pass.
void setPreservesAll()
Set by analyses that do not transform their input at all.
AnalysisUsage & addRequiredTransitive()
Legacy analysis pass which computes a DominatorTree.
FunctionPass class - This class is used to implement most global optimizations.
This is an alternative analysis pass to BlockFrequencyInfoWrapperPass.

releaseMemory() - This member can be implemented by a pass if it wants to be able to release its memo...
bool runOnFunction(Function &F) override
runOnFunction - Virtual method overriden by subclasses to do the per-function processing of the pass.
static void getLazyBFIAnalysisUsage(AnalysisUsage &AU)
Helper for client passes to set up the analysis usage on behalf of this pass.
void print(raw_ostream &OS, const Module *M) const override
print - Print out the internal state of the pass.
void getAnalysisUsage(AnalysisUsage &AU) const override
getAnalysisUsage - This function should be overriden by passes that need analysis information to do t...
static void getLazyBPIAnalysisUsage(AnalysisUsage &AU)
Helper for client passes to set up the analysis usage on behalf of this pass.
The legacy pass manager's analysis pass to compute loop information.
A Module instance is used to store all the information related to an LLVM module.
