Hi all,
I am trying to understand the role of the LLVM auto-vectorizer in TVM. Indeed, in `llvm_codegen.cc` we explicitly set: ``` builder.LoopVectorize = true; builder.SLPVectorize = true; ``` And I am trying to determine to what level TVM is relying on LLVM auto-vectorization. ### What is my understanding As far as I understood, TVM implements its own vectorizer in `vectorize_loop.cc` (which is a TIR pass). So if a loop is vectorized in TVM, the LLVM autovectorization won't be used. If instead a loop is not vectorized in TVM, the LLVM autovectorizer will kick in and try to vectorize the loop. Is my understanding correct? Does this mean that, for most operators like `conv2d` or `gemm` the LLVM autovectorizer would be mostly ineffective? cc @ramana-arm, @matt-arm, @manupa-arm --- [Visit Topic](https://discuss.tvm.apache.org/t/role-of-the-llvm-autovectorizer-in-tvm/8388/1) to respond.
