Thanks Ayal! I'll take a look at DENBench. As another data point - I tried enabling this on our internal benchmarks. I'm seeing one regression, and it seems to be a regression of the "good" kind - without interleaving we don't vectorize the innermost loop, and with interleaving we do. The vectorized loop is actually sign...

...a reproducer), turn it off again and go back to analysis. But I'd strongly prefer to "prefetch" the problem.

...dding "*out++ = 0" right after "*out++ = q;" (thus eliminating the pesky <12 x i8>), we get: Indeed such padding is a known (programmer) optimization to effectively have power-of-2 strides and/or alignment. > So, unfortunately, it turns out I don't have access to DENBench. If you like we could test your patch to see how it (mis)behaves.

We checked the gathered data again. All regressions that we see are in 32-bit mode. The 64-bit mode looks good overall. - Elena From: Michael Kuperstein [mailto:mkuper at google.com] Sent: Saturday, August 06, 2016 02:56 To: Renato Golin <renato.golin at linaro.org> Cc: Demikhovsky, Elena <elena.demikhovsky at intel.com>; Matthew Simpson <mssimpso at codeaurora.org>;
