class MemoryAccess

Declaration

class MemoryAccess : public DerivedUser,
                     public ilist_node,
                     public ilist_node { /* full declaration omitted */ };

Description

Extension point for the Value hierarchy. All classes outside of lib/IR that wish to inherit from User should instead inherit from DerivedUser instead. Inheriting from this class is discouraged. Generally speaking, Value is the base of a closed class hierarchy that can't be extended by code outside of lib/IR. This class creates a loophole that allows classes outside of lib/IR to extend User to leverage its use/def list machinery.

Methods

¶MemoryAccess(
    llvm::LLVMContext& C,
    unsigned int Vty,
    llvm::DerivedUser::DeleteValueTy DeleteValue,
    llvm::BasicBlock* BB,
    unsigned int NumOperands)

Declared at: llvm/include/llvm/Analysis/MemorySSA.h:219

Parameters

llvm::LLVMContext& C

unsigned int Vty

llvm::DerivedUser::DeleteValueTy DeleteValue

llvm::BasicBlock* BB

unsigned int NumOperands

¶MemoryAccess(const llvm::MemoryAccess&)

Declared at: llvm/include/llvm/Analysis/MemorySSA.h:148

Parameters

const llvm::MemoryAccess&

¶static bool classof(const llvm::Value* V)

Declared at: llvm/include/llvm/Analysis/MemorySSA.h:155

Parameters

const llvm::Value* V

¶llvm::memoryaccess_def_iterator defs_begin()

Description

This iterator walks over all of the defs in a given MemoryAccess. For MemoryPhi nodes, this walks arguments. For MemoryUse/MemoryDef, this walks the defining access.

Description

Get the iterators for the all access list and the defs only list We default to the all access list.
