Hi, i am interested in knowing if the C51 compiler is able to define initrisic functions... I mean if there is a way I can define a function that is expanded inline in the assembly language and there are no CALLs or RETs generated for it. I know there are some built in intrisic funtions in C51 like _iror_ _irol_ and the like, but i wonder if it is possible to define new ones. Any informations on this?
