Hi Renato, Thanks for working on this. As you said, we don't support pointer reductions. Handling pointer reductions should be straightforward. You can copy the logic for handling RK_IntegerAdd and create a new enum entry for RK_PointerAdd. You will need to detect the relevant patterns (GEP probably) and implement the cost model and vectorization parts. You will need to generate

Hi Nadav, Arnold, (now copying LLVM-dev, not commits), I'm working on an example of a code that current GCC trunk can vectorize but LLVM cannot, and after analysing the intermediate IR just before the loop vectorization and by stepping through the process, I can see that the vectorizer only recognizes integer and float reduction variables, not pointers. My code looks like this: for (i: 0
