Support for the following three builtins are added: __builtin_sycl_is_single_task_kernel(function-pointer) __builtin_sycl_is_nd_range_kernel(function-pointer, dimension) __builtin_sycl_is_kernel(function-pointer) __builtin_sycl_is_single_task_kernel returns true if the function pointer represents a function with the IR attribute "sycl-single-task-kernel". __builtin_sycl_is_nd_range_kernel returns true if the function pointer represents a function with the IR attribute "sycl-single-task-kernel" with a matching dimension. __builtin_sycl_is_kernel returns true if the function pointer represents a function with either of the two IR attributes.

Can you explain what passing the type to the getTrue( ) API does here? Is it possible to just return 0 or 1 if you are converting to ConstantInt anyway?

I am not that familiar with this - but passing the type makes the function return a true value in the context of the type. There is another interface for getTrue, but it takes the LLVM context as its argument and returns a true value in that context. Passing the type made more sense and that is what other builtins seem to do too.

Thank you for explaining

__builtin_sycl_is_single_task_kernel returns true if the function pointer represents a function with the IR attribute "sycl-single-task-kernel".
__builtin_sycl_is_nd_range_kernel returns true if the function pointer represents a function with the IR attribute "sycl-single-task-kernel" with a matching dimension.
__builtin_sycl_is_kernel returns true if the function pointer represents a function with either of the two IR attributes.
