This is an optimization pass for GlobalISel generic memory operations.
Lazy Branch Probability true
void print(raw_ostream &OS, const Module *M) const override
print - Print out the internal state of the pass.
void initializeLazyBranchProbabilityInfoPassPass(PassRegistry &)
The legacy pass manager's analysis pass to compute loop information.
static PassRegistry * getPassRegistry()
getPassRegistry - Access the global registry object, which is automatically initialized at applicatio...
Represent the analysis usage information of a pass.
static void getLazyBPIAnalysisUsage(AnalysisUsage &AU)
Helper for client passes to set up the analysis usage on behalf of this pass.
Legacy analysis pass which computes a DominatorTree.
PassRegistry - This class manages the registration and intitialization of the pass subsystem as appli...
This class implements an extremely fast bulk output stream that can only output to a stream.
void getAnalysisUsage(AnalysisUsage &AU) const override
getAnalysisUsage - This function should be overriden by passes that need analysis information to do t...
unsigned ID
LLVM IR allows to use arbitrary numbers as calling convention identifiers.

INITIALIZE_PASS_DEPENDENCY(DominatorTreeWrapperPass)
void initializeLazyBPIPassPass(PassRegistry &Registry)
Helper for client passes to initialize dependent passes for LBPI.
A Module instance is used to store all the information related to an LLVM module.
void setPreservesAll()
Set by analyses that do not transform their input at all.
Provides information about what library functions are available for the current target.
bool runOnFunction(Function &F) override
runOnFunction - Virtual method overriden by subclasses to do the per-function processing of the pass.

AnalysisUsage & addRequiredTransitive()
FunctionPass class - This class is used to implement most global optimizations.
This is an alternative analysis pass to BranchProbabilityInfoWrapperPass.
