[LLVMdev] Enabling the vectorizer for -Os -- ping
All I have to say is *wow*. The vectorizer performs *remarkably* better now
than it did the last time I benchmarked it. I'm stunned.
I measured -O2 and -Os, as well as -march=x86-64 and -march=corei7-avx. My
hope with the latter two was to cover both worst-case and best-case in
terms of the quality of the vector ISA available.
First, binary size growth. This is measured on average across a
