//
//      namespace__kname__012345__suffix
//
// or, when suffix is NULL:
//
//      namespace__kname__012345
//
// where "012345" is a hexadecimal printing of the scode.  Note the double

// parsing the kernel_name of a PreJIT kernel.

// The suffix is used only for user-defined types and operators.
