This option is used when the user wants to avoid emitting double precision FP loads and stores. Double precision FP loads and stores are expanded to single precision instructions after register allocation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181718 91177308-0d34-0410-b5e6-96231b3b80d8
