// Generate an OpenCL source file containing a call to each builtin from
// OpenCLBuiltins.td and then run that generated source file through the
// frontend.
//
// Then test that:
//  - The generated file can be parsed using opencl-c.h, giving some confidence
//    that OpenCLBuiltins.td does not provide more than what opencl-c.h provides
//    (but not vice versa).
//
//  - The generated file can be parsed using -fdeclare-opencl-builtins, ensuring
//    some internal consistency of declarations in OpenCLBuiltins.td.  For
//    example, addition of builtin declarations that lead to ambiguity during
//    overload resolution will cause this test to fail.
