Re: NewQ: Difference between an isr and a subroutine is that an isr has no arguments

The hardware could set up a few registers and the compiler
would assign parameters to those registers on functions marked
as interrupts - very easy to implement. You could ignore them if
you didn't support them.

All of the processors I've used already do that (store return
address and status information in a known location), so I guess
all that's missing is a few lines of code in the compilers.
