The PPCTargetLowering::SelectAddressRegImm routine needs to handle FrameIndex nodes in a special manner, by tranlating them into a TargetFrameIndex node. This was done in most cases, but seems to have been neglected in one path: when the input tree has an OR of the FrameIndex with an immediate. This can happen if the FrameIndex can be proven to be sufficiently aligned that an OR of that immediate is equivalent to an ADD. The missing handling of FrameIndex in that case caused the SelectionDAG instruction selection to miss opportunities to merge the OR back into the FrameIndex node, leading to superfluous addi/ori instructions in the final assembler output. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@213482 91177308-0d34-0410-b5e6-96231b3b80d8
