<p>Hi,<br>
</p>
<p><br>
</p>
<p>please find attached a patch that ports costCoeffNxN to arm64.<br>
</p>
<p>The patch speeds up costCoeffNxN by 1.4x on Graviton2:<br>
</p>
<p><br>
</p>
<p><br>
</p>
<p>I have also attached a patch to fix the output of <span style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px; background-color: rgb(255, 255, 255);">./x265 -V</span> that used to print 32bit instead of 64bit on arm64.<br>
