<p class="MsoNormal">Hi all,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The attached patch contains implementation for turning OpenCL size_t and ptrdiff_t types to builtin types (on top of my previous patch).<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">This patch needs some additional polishing, like addition of size_t specific tests and changing some names.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">In spite of the issues above, I find it very important to send this mail before the LLVM developers’ conference. During the conference we will hold a SPIR BOF session, and this patch will be used to explain some aspects of the SPIR approach.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Please review<o:p></o:p></p>
