[Florian Hahn via Phabricator via llvm-commits]

fhahn added inline comments.


================
Comment at: llvm/test/Analysis/LoopAccessAnalysis/forked-pointers.ll:987
+  %1 = or i64 %indvars.iv, 1
+  %arrayidx = getelementptr inbounds [2048 x i8], ptr %0, i64 0, i64 %indvars.iv
+  store i8 3, ptr %arrayidx
----------------
I'm not sure if/how this fits into the forked pointer handling. The forked pointer handling is to support cases where a GEP can have multiple base pointers (e.g. due to a select or phi). But in this case there are 2 distinct GEPs each with their separate base pointer.
