Detailed Description

MachinePointerInfo - This class contains a discriminated union of information about pointers in memory operands, relating them back to LLVM IR or to virtual locations (such as frame indices) that are exposed during codegen.

int64_t llvm::MachinePointerInfo::Offset

Offset - This is an offset from the base Value*.

Definition at line 39 of file MachineMemOperand.h.

Referenced by llvm::MachineMemOperand::getOffset(), getWithOffset(), and llvm::MachineMemOperand::setOffset().

const Value* llvm::MachinePointerInfo::V

V - This is the IR pointer value for the access, or it is null if unknown. If this is null, then the access is to a pointer in the default address space.
