<div dir="ltr">Hi Hal,<div><br></div><div>I ran some numbers on Cortex-A57 (AArch64 mode) with the SLP and Loop vectorizers swapped and with your noalias metadata enabled. I see no change outside of noise. I ran SPEC(2000+2006) and EEMBC - LNT is currently unusable on our hardware due to lack of "perf" - it's just too noisy :(</div>
<div><br></div><div>Can someone try a test on x86? If that shows the same, we should be in a good position to swap the ordering as soon as you enable noalias metadata by default.</div><div><br></div><div>Cheers,</div><div>

If you send me a patch, I can provide some numbers as well.<br>
