Another thing we probably want to depend on: a little-endian architecture. There is an assumption in the code that the CPU will use this endianness, and while it can be changed to be more portable, this would require stuff like proc-macros to properly build a struct from a data stream with endianness in mind, which we don't have yet. Most (all?) the platforms on which NVIDIA GPUs are to run are little-endian anyway, so I am not even sure big-endian support would be useful.
