Is it not possible to mix the register calling convention with the
normal, and so all that would be needed is to make all the functions
that are in C '__attribute__ ((regparam(3)))' (or a relavant number) .
As far as I know the compiler and linker would then deal with it
itself. Please correct me if I am wrong though as I am interrested in
this to use in my own programs.
