Anastasia added inline comments.
================
Comment at: clang/test/SemaOpenCL/fdeclare-opencl-builtins.cl:35
+// Enable extensions that are enabled in opencl-c-base.h.
+#if (defined(__OPENCL_CPP_VERSION__) || __OPENCL_C_VERSION__ >= 200)
+#define cl_khr_subgroup_ballot 1
----------------
Not related to this patch - I think we should have included `opencl-c-base.h`
by default when passing `-fdeclare-opencl-builtins` or do you see any issues
with that?
================
Comment at: clang/test/SemaOpenCL/fdeclare-opencl-builtins.cl:141
+kernel void extended_subgroup(global uint4 *out) {
+ out[0] = get_sub_group_eq_mask();
+#if __OPENCL_C_VERSION__ < CL_VERSION_2_0 && !defined(__OPENCL_CPP_VERSION__)
----------------
I appreciate we haven't addressed the standard header testing holistically yet
and this functionality was added in `opencl-c.h` without testing the functions,
but would it be better to test each function at least here?
Even though the final goal should be testing all overloads, this is outside of
the scope of this work that is closing the gap between `opencl-c.h` and this
experimental function declaration mechanism.
