The iaddroff ComplexPattern is supposed to recognize displacement expressions that have been processed by a SelectAddressRegImm, which means it needs to accept TargetConstant and TargetGlobalAddress nodes. Currently, it erroneously also accepts some other nodes, in particular Constant and PPCISD::Lo. While this problem is currently latent, it would cause wrong-code bugs with a follow-on patch I'm about to commit, so this patch tightens the ComplexPattern. The equivalent change is made in PPCDAGToDAGISel::Select, where pre-inc load patterns are handled (as opposed to store patterns, the loads are handled in C++ code without making use of the .td ComplexPattern). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177732 91177308-0d34-0410-b5e6-96231b3b80d8
