Member Data Documentation

◆ ContainsCalls

bool llvm::ClonedCodeInfo::ContainsCalls = false

This is set to true if the cloned code contains a normal call instruction.

Definition at line 65 of file Cloning.h.

Referenced by llvm::CloneBasicBlock(), HandleInlinedEHPad(), HandleInlinedLandingPad(), and llvm::InlineFunction().

◆ ContainsDynamicAllocas

bool llvm::ClonedCodeInfo::ContainsDynamicAllocas = false

This is set to true if the cloned code contains a 'dynamic' alloca.

Dynamic allocas are allocas that are either not in the entry block or they are in the entry block but are not a constant size.

Referenced by llvm::CloneBasicBlock(), and llvm::InlineFunction().

◆ ContainsMemProfMetadata

bool llvm::ClonedCodeInfo::ContainsMemProfMetadata = false

This is set to true if there is memprof related metadata (memprof or callsite metadata) in the cloned code.

Definition at line 69 of file Cloning.h.

Referenced by llvm::CloneBasicBlock(), and llvm::InlineFunction().

◆ OperandBundleCallSites

std::vector<WeakTrackingVH> llvm::ClonedCodeInfo::OperandBundleCallSites

All cloned call sites that have operand bundles attached are appended to this vector.

This vector may contain nulls or undefs if some of the originally inserted callsites were DCE'ed after they were cloned.

Definition at line 79 of file Cloning.h.

Referenced by llvm::InlineFunction().

◆ OrigVMap

DenseMap<const Value *, const Value *> llvm::ClonedCodeInfo::OrigVMap

Like VMap, but maps only unsimplified instructions.

Values in the map may be dangling, it is only intended to be used via isSimplified(), to check whether the main VMap mapping involves simplification or not.
