[LLVMdev] Redundant Add Operation in Code Generation?

[LLVMdev] Enabling vectorization with LLVM 3.3 for a DSL emitting LLVM IR
Hi,
Our DSL can generate C or directly generate LLVM IR. With LLVM 3.3, we can vectorize the C produced code using clang with -O3, or clang with -O1 then opt -O3 -vectorize-loops. But the same program generating LLVM IR version cannot be vectorized with opt -O3 -vectorize-loops. So our guess is that our generated LLVM IR lacks some informations that are needed by the vectorization passes to
