Am I missing something here? Why not pop to assembler, push the high, push the low, pop the high, pop the low?
* Inline assembler cannot be used at compile time, for example to initialize a static variable. * If the swap function is called on a constant, the compiler cannot remove the inline assembler. In general, any inline assembler tends to handcuff the optimizer to some degree. * Push and pop take two cycles since they access memory. Three mov instructions are faster than one push and one pop.
