 The ``noduplicate`` attribute can be placed on function declarations to control

-whether function calls to this function can be duplicated 

-or not as a result of optimizations. This is required for the implementation

-of functions with certain special requirements, like the OpenCL "barrier", 

-function that, depending on the hardware, might require to be run concurrently

-by all the threads that are currently executing in lockstep on the hardware.

-For example this attribute applied on the function "nodupfunc"
