<div dir="ltr"> In <a href="http://llvm.org/docs/Vectorizers.html">http://llvm.org/docs/Vectorizers.html</a>, it says "LLVM’s Loop Vectorizer is now enabled by default for -O3". But I use the following command: opt -O3 -debug-pass=Arguments test.ll -o /dev/null I can't see the "loop-vectorize" option in the result. Any advice ? <div style>
