</blockquote>
<p>IIRC padding stuff, not really. Alignment of each data member depends on its size. E.g. if a data member has 8 byte size, then it will be aligned on 8 byte boundaries; if a data member has 4 byte size, then it will be aligned on 4 byte boundaries. Now, if you have uint32_t before uint64_t, there will be 4 byte hole.</p>
<p>Also, I, personally, think this optimization is not worth it. It would matter if we have, say, millions of outputs.</p></div></div><br /><div><strong>REPOSITORY</strong><div><div>R110 KScreen Library</div></div></div><br /><div><strong>REVISION DETAIL</strong><div><a href="https://phabricator.kde.org/D14353">https://phabricator.kde.org/D14353</a></div></div><br /><div><strong>To: </strong>gladhorn, Plasma, romangg<br /><strong>Cc: </strong>zzag, romangg, plasma-devel, ragreen, Pitel, ZrenBot, lesliezhai, ali-mohamed, jensreuterberg, abetts, sebas, apol, mart<br /></div>
