Each SM and PTX version is modeled as a subtarget feature/CPU. Additionally, PTX 3.1 is added as the default PTX version to be out-of-the-box compatible with CUDA 5.0. Available CPUs for this target: sm_10 - Select the sm_10 processor. sm_11 - Select the sm_11 processor. sm_12 - Select the sm_12 processor. sm_13 - Select the sm_13 processor. sm_20 - Select the sm_20 processor. sm_21 - Select the sm_21 processor. sm_30 - Select the sm_30 processor. sm_35 - Select the sm_35 processor. Available features for this target: ptx30 - Use PTX version 3.0. ptx31 - Use PTX version 3.1. sm_10 - Target SM 1.0. sm_11 - Target SM 1.1. sm_12 - Target SM 1.2. sm_13 - Target SM 1.3. sm_20 - Target SM 2.0. sm_21 - Target SM 2.1. sm_30 - Target SM 3.0. sm_35 - Target SM 3.5. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167699 91177308-0d34-0410-b5e6-96231b3b80d8
