Isn't cheating allowed? Write the original OS in C, then compile, and then work on the resultant assembly code, first on optimizing, and then on adding features?
Writing C code and playing with the generated assembly might be OK for a day or two's work in learning assembly on a particular architecture. However for any half serious project its probably a terrible way to get started.
Assembly programming is not about trying to out code generate a compiler. Its about thinking of implementations that are not restricted by the semantics of a particular high level language, of being able to leverage knowledge that can not be given to the compiler, of thinking in terms of the actual hardware architecture.
