Still LGTM with a couple of nits.



================
Comment at: llvm/lib/Target/NVPTX/NVPTXAliasAnalysis.cpp:72
+                                 const MemoryLocation &Loc2, AAQueryInfo &AAQI,
+                                 const Instruction *CtxI) {
+  unsigned AS1 = Loc1.Ptr->getType()->getPointerAddressSpace();
----------------
`CtxI` does not seem to be used. Do we need it?


================
Comment at: llvm/lib/Target/NVPTX/NVPTXAliasAnalysis.cpp:90
+                                            bool IgnoreLocals) {
+  unsigned AS = Loc.Ptr->getType()->getPointerAddressSpace();
+  if (isConstOrParam(AS))
----------------
IMO, the code would be more readable w/o the variable. Just do `if (isConstOrParam(Loc.Ptr->getType()->getPointerAddressSpace()))` directly here and below.

Having the variable makes me, as a reader, ask -- "what was the variable set to before?", "what else is this variable used for?" and that's just a distraction here.
