eugenis added a comment. The test should be in LLVM, under test/Instrumentation/MemorySanitizer
================ Comment at: llvm/lib/Transforms/Instrumentation/MemorySanitizer.cpp:3077 + Value *LowShadow = IRB.CreateOr(LowA, LowB); + Value *Shadow = IRB.CreateInsertElement(Second, LowShadow, IRB.getInt32(0)); + ---------------- You probably want to insert in First, not Second. Is the generated code any better if you OR the vectors, and then shuffle to put the top element of First into the top element of the output? That's what LLVM generates if I express this logic in C.
