The PTX ISA specifies that initializers may be incomplete ([5.4.4. Initializers](https://docs.nvidia.com/cuda/parallel-thread-execution/index.html#initializers)) > As in C, array initializers may be incomplete, i.e., the number of initializer elements may be less than the extent of the corresponding array dimension, with remaining array locations initialized to the default value for the specified array type. Emitting initializers in this form is preferable because it reduces the size of the PTX, in some cases significantly, and can improve compile time of ptxas as a result.
