function arguments are passed in registers

[Zheng Da]

Suppose I have two libraries, A and B.
In library A, there is function a() whose arguments are passed in registers.
In library B, there is b() whose arguments are passed in the stack.
Now I have to use a() and b() in my program.
But how do I tell GCC that they use different ways to pass the
arguments and which is the right way.
