<p class="MsoNormal"><span lang="EN-GB" style="color:#1F497D">Those types are part of C99 too and it is rather common to define them in the header files. I wouldn’t overcomplicate Clang code with adding them unless there is a real benefit in that.

<p class="MsoNormal"><span lang="EN-GB" style="color:#1F497D">I think inclusion of headers is unavoidable anyways as we can’t add everything from CL libs into Clang directly without affecting it’s performance.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:#1F497D">I agree it is better to define the vector types and probably the size_t, ptrdiff_t, intptr_t, uintptr_t types in Clang instead of header file. This allows user to use these types without include the header.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="RU"><o:p> </o:p></span></p>
<p class="MsoNormal">OpenCL 2.0 supports blocks as core feature. However, Clang does not turn on blocks support by default for OpenCL 2.0. An option –fblocks has to be used to turn on blocks.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Should this be changed?<o:p></o:p></p>
