multiple code sections

Is it possible to define multiple code (.text) sections within an object file?

For instance:

[ text ]

[ text_a ]

[ text_b ]

[ text_c ]

Where 'text' contains the actual code for the object file. text_a will refer to/get loaded with code from another object file ........... and so on. How can I achieve this? I'm using NIOS II IDE version 8
