It would allow us to more easily adopt C++11's <tt style="background: #ebebeb; font-size: 13px;">thread_local</tt> once we remove support for older compilers. I also looked into whether we could adopt the higher-quality RNGs that should be available in C++11, but getting them seeded is apparently very difficult to do without introducing errors.</p>
<p>Also, I'd recommend using <tt style="background: #ebebeb; font-size: 13px;">quintptr</tt> instead of <tt style="background: #ebebeb; font-size: 13px;">intptr_t</tt> in the reinterpret_cast, as that seems more accurate for the semantics of XOR. The shift to XOR is a great idea though.</p></div></div><br /><div><strong>REPOSITORY</strong><div><div>R244 KCoreAddons</div></div></div><br /><div><strong>REVISION DETAIL</strong><div><a href="https://phabricator.kde.org/D5966" rel="noreferrer">https://phabricator.kde.org/D5966</a></div></div><br /><div><strong>To: </strong>tfry, dfaure<br /><strong>Cc: </strong>mpyne, tfry, rjvbb, Frameworks<br /></div>
