class PseudoSourceValue

Declaration

class PseudoSourceValue { /* full declaration omitted */ };

Description

Special value supplied for machine level alias analysis. It indicates that a memory access references the functions stack frame (e.g., a spill slot), below the stack frame (e.g., argument space), or constant pool.

                  const llvm::TargetMachine& TM)

Declared at: llvm/include/llvm/CodeGen/PseudoSourceValue.h:62

Parameters

unsigned int Kind

const llvm::TargetMachine& TM

¶unsigned int getAddressSpace() const

Declared at: llvm/include/llvm/CodeGen/PseudoSourceValue.h:73

¶unsigned int getTargetCustom() const

Declared at: llvm/include/llvm/CodeGen/PseudoSourceValue.h:75

¶virtual bool isAliased(
    const llvm::MachineFrameInfo*) const

Description

Test whether the memory pointed to by this PseudoSourceValue may also be pointed to by an LLVM IR Value.

Declared at: llvm/include/llvm/CodeGen/PseudoSourceValue.h:85

Parameters

const llvm::MachineFrameInfo*

¶virtual bool isConstant(
    const llvm::MachineFrameInfo*) const

Description

Test whether the memory pointed to by this PseudoSourceValue has a constant value.

Declared at: llvm/include/llvm/CodeGen/PseudoSourceValue.h:81

Parameters

const llvm::MachineFrameInfo*

¶bool isConstantPool() const

Declared at: llvm/include/llvm/CodeGen/PseudoSourceValue.h:70

¶bool isGOT() const

Declared at: llvm/include/llvm/CodeGen/PseudoSourceValue.h:69

¶bool isJumpTable() const

¶virtual bool mayAlias(
    const llvm::MachineFrameInfo*) const

Description
