On PowerPC, non-vector loads and stores have r+i forms; however, in functions with large stack frames these were not being used to access slots far from the stack pointer because such slots were out of range for the signed 16-bit immediate offset field. This increases register pressure because we need a separate register for each offset (when the r+r form is used). By enabling virtual base registers, we can deal with large stack frames without unduly increasing register pressure. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179105 91177308-0d34-0410-b5e6-96231b3b80d8
