cuda - nvcc -arch sm_52 gives error "Value 'sm_52' is not defined for option 'gpu-architecture'" -

i updated cuda toolkit 5.5 6.5. following command

nvcc -arch=sm_52 

starts give me error

nvcc fatal   : value 'sm_52' not defined option 'gpu-architecture' 

is bug ? or nvcc 6.5 not support maxwell virtual architecture.

cuda toolkit 6.5 released before sm_52 architecture came production.

after arrival of sm_52 architecture, update cuda 6.5 released enabled nvcc generate code sm_52.

make sure download newer version of cuda toolkit 6.5.

p.s: rather use latest version of toolkit (currently 7.0).
