<p>Hi Jon,</p>
<p>There's currently no way to qualify a method with an arbitrary address space. There is a work-in-progress patch on it:</p>
<p><a class="moz-txt-link-freetext" href="https://reviews.llvm.org/D57464">https://reviews.llvm.org/D57464</a></p>
<p>and I have an experimental local patch that tries to alleviate some issues with the patch above, but it doesn't really work. Parsing this pattern properly is unfortunately rather difficult. There's also no real syntax support in C++ for qualified constructors/destructors,
which is another problem.<br>
</p>
<p>/ Bevin<br>

<div>How should I be spelling this? I'm essentially trying to replicate cuda's __shared__. Ideally I'd like implicit conversions to a and from an int which is not address space qualified, but right now I'm stuck on the constructor.</div>
