Hi, Last week I wrote llvm-dev and presented data that shows how enabling the vectorizer on -Os can improve the performance of many workloads and that it has negligible effects on code size. I also added a command line switch to make it easier for people to benchmark the vectorizer using -Os directly from clang without changing LLVM. Has anyone done any benchmarks on -Os + vectorization ?
