class MachineBranchProbabilityInfo

Declaration

class MachineBranchProbabilityInfo : public ImmutablePass { /* full declaration omitted */ };

Description

ImmutablePass class - This class is used to provide information that does not need to be run. This is useful for things like target information and "basic" versions of AnalysisGroups.

Methods

¶MachineBranchProbabilityInfo()

Declared at: llvm/include/llvm/CodeGen/MachineBranchProbabilityInfo.h:38

¶void getAnalysisUsage(
    llvm::AnalysisUsage& AU) const

Description

getAnalysisUsage - This function should be overriden by passes that need analysis information to do their job. If a pass specifies that it uses a particular analysis result to this function, it can then use the getAnalysis <AnalysisType >() function, below.

Declared at: llvm/include/llvm/CodeGen/MachineBranchProbabilityInfo.h:40

Parameters

llvm::AnalysisUsage& AU

¶llvm::BranchProbability getEdgeProbability(
    const llvm::MachineBasicBlock* Src,
    const llvm::MachineBasicBlock* Dst) const

Declared at: llvm/include/llvm/CodeGen/MachineBranchProbabilityInfo.h:45

Parameters

const llvm::MachineBasicBlock* Src

const llvm::MachineBasicBlock* Dst

¶llvm::BranchProbability getEdgeProbability(
    const llvm::MachineBasicBlock* Src,
