As you said, I copied sha512block from cryptsha512_kernel_GCN.cl for
gcn and cryptsha512_kernel_GPU.cl for others
and I included
#if !gpu_nvidia(DEVICE_INFO) || nvidia_sm_5x(DEVICE_INFO)
#define USE_BITSELECT
#elif gpu_nvidia(DEVICE_INFO)
#define OLD_NVIDIA
#endif
I don't use USE_BITSELECT or OLD_NVIDIA but it's faster on my laptop
and I resigned from vectors, was slower with them
