[LLVMdev] Loads/Stores and MachineMemOperand
I want to get some clarification on the exact semantics of the
MachineMemOperand attached to memory-touching instructions. From what I
understand, a MemSDNode has an associated MachineMemOperand and a
MachineInstr can have zero or more attached MachineMemOperands.
But what is the guarantee/constraint placed on optimization/codegen passes
for maintaining the contents of a MachineMemOperand? In
