Detailed Description

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.
