refineAlignment()

void llvm::MemSDNode::refineAlignment ( const MachineMemOperand *  NewMMO )

inline

Update this MemSDNode's MachineMemOperand information to reflect the alignment of NewMMO, if it has a greater alignment.

This must only be used when the new alignment applies to all users of this MachineMemOperand.
