AMD GCN

These options are defined specifically for the AMD GCN port.

       -march=gpu
       -mtune=gpu
           Set architecture type or tuning for gpu. Supported values for
           gpu are

           fiji
               Compile for GCN3 Fiji devices (gfx803).

           gfx900
               Compile for GCN5 Vega 10 devices (gfx900).

       -mstack-size=bytes
           Specify how many bytes of stack space will be requested for
           each GPU thread (wave-front).  Beware that there may be many
           threads and limited memory available.  The size of the stack
           allocation may also have an impact on run-time performance.
           The default is 32KB when using OpenACC or OpenMP, and 1MB
           otherwise.
