Well, what you really want is to re-order functions, not object files. 
How classicly you do this is that the compiler places each function in 
its own section and then you thell linker how you want the sections 
ordered within a segment. Though yes, if you can have only section per 
object file and not function then it regresses to object file re-ordering. 

The linker and libraries guide (http://docs.sun.com/db/doc/816-1386) has 
all (or at least most) the gory details.
