Detailed Description

MachineMemOperand - A description of a memory reference used in the backend. Instead of holding a StoreInst or LoadInst, this class holds the address Value of the reference along with a byte size and offset. This allows it to describe lowered loads and stores. Also, the special PseudoSourceValue objects can be used to represent loads and stores to memory locations that aren't explicit in the regular LLVM IR.

Member Enumeration Documentation

enum llvm::MachineMemOperand::MemOperandFlags

Flags values. These may be or'd together.

Enumerator:

MOLoad	The memory access reads data.
MOStore	The memory access writes data.
MOVolatile	The memory access is volatile.

Member Function Documentation

const Value* llvm::MachineMemOperand::getValue ( ) const [inline]

getValue - Return the base address of the memory access. Special values are PseudoSourceValue::FPRel, PseudoSourceValue::SPRel, and the other PseudoSourceValue members which indicate references to frame/stack pointer relative references and other special references.

Definition at line 58 of file MachineMemOperand.h.

unsigned int llvm::MachineMemOperand::getFlags ( ) const [inline]

getFlags - Return the raw flags of the source value,

See also:: MemOperandFlags.

Definition at line 61 of file MachineMemOperand.h.

int64_t llvm::MachineMemOperand::getOffset ( ) const [inline]

getOffset - For normal values, this is a byte offset added to the base address. For PseudoSourceValue::FPRel values, this is the FrameIndex number.

uint64_t llvm::MachineMemOperand::getSize ( ) const [inline]

getSize - Return the size in bytes of the memory reference.

unsigned int llvm::MachineMemOperand::getAlignment ( ) const [inline]

getAlignment - Return the minimum known alignment in bytes of the memory reference.
