[PATCH] D28394: [AliasAnalysis] Limit `MemoryLocation` retrieval to valid intrinsic arguments.

[Philip Reames via Phabricator via llvm-commits]

reames added inline comments.


================
Comment at: lib/Analysis/AliasAnalysis.cpp:177
+        unsigned ArgIdx = A.Index;
+        if (!Arg->getType()->isPointerTy() || CS.doesNotAccessMemory(ArgIdx))
           continue;
----------------
I'm missing something here.  *Why* is it problematic to ask for a memory location of the parameter to invariant_end?  I would expect that to just work.
