_weight_int4pack_mm_cuda / _convert_weight_to_int4pack_cuda gate on !defined(__CUDA_ARCH__) || (__CUDA_ARCH__ >= 800) , with a TORCH_CHECK(false, ...) in the other arm. Both are host functions, and __CUDA_ARCH__ is only defined during nvcc's device compilation pass -- so !defined(__CUDA_ARCH__) is always true when this is preprocessed for the host, and the check is unreachable in every build. The "requires sm_80" co…
