- Allow i16, i32, i64, float, and double types, using the native .u16, .u32, .u64, .f32, and .f64 PTX types. - Allow loading/storing of all primitive types. - Allow primitive types to be passed as parameters. - Allow selection of PTX Version and Shader Model as sub-target attributes. - Merge integer/floating-point test cases for load/store. - Use .u32 instead of .s32 to conform to output from NVidia nvcc compiler.
