To get good results, we can use an important insight that is not documented anywhere at any length: we can use 64-bit processor instructions to do 32-bit arithmetic. I expect that the compiler will turn this code into a sequence of instructions over 32-bit registers: uint32_t compilermod32 ( uint32_t a ) {. My source code is available.

By definition, if a function’s preconditions are violated, then the results are not specified.
