In addition to the regular loop unrolling transformation, the loop vectorizer can also unroll loops. If no unrolling has specifically been requested (by -fno-unroll-loops), and the loop vectorizer will be used, then add the backend option to (also) prevent the loop vectorizer from unrolling loops. I confirmed with Nadav (off list) that disabling vectorizer loop unrolling when -fno-unroll-loops is provided is the desired behavior. llvm-svn: 189440 |
