/* Enable double precision. This should really only be done when
   building the run-time library; when building application code, we
   should instead check a macro to see whether the application has
   enabled this. At the moment, always enable this seems fine, since
   all our target devices will support double precision anyway.

   FIX: this is not really true. TCE target is 32-bit scalars
   only. Seems the pragma does not add the macro, so we have the target
   define the macro and the pragma is conditionally enabled.

// We provide our own printf

// we implement it in C using a const format string (i.e. a format
// string living in a different address space). This works only if all
// address spaces are actually the same, e.g. on CPUs.
// Note: We cannot use __attribute__((format(printf, 1, 2))), since
// Clang doesn't support the OpenCL C format specifiers yet.
