<p>Hi Xiuli,<o:p></o:p></p>
<p>This looks like a simple attribute to parse, __attribute__((intel_reqd_sub_group_size(<int>))), and I don't see why this would be controversial. I recommend just sending a patch for review.<o:p></o:p></p>

I'm assuming that you're just going to emit corresponding kernel metadata. If the handling will be more involved than that, then it might be worth discussing beforehand.<br>

<p class="MsoNormal"><span style="color:#1F497D">We are now enabling some Intel OpenCL extension and find in extension cl_intel_required_subgroup_size (<a href="https://www.khronos.org/registry/OpenCL/extensions/intel/cl_intel_required_subgroup_size.txt">https://www.khronos.org/registry/OpenCL/extensions/intel/cl_intel_required_subgroup_size.txt</a>)
has an attribute intel_reqd_sub_group_size that is very useful for intel subgroup usage and does not supported by clang now. And I want to send a patch to enable it, what do you think about this?
