Calling conventions used by gcc

[Anders Schau Knatten]

I am trying to find some info on calling conventions used by g++ and g77,  
but I cannot find anything in the manuals [1] and [2]. Does anyone know  
any other sources I could check? What I am looking for is what calling  
convention is used by default by g++ and g77 on linux/ia64, and how to  
change this if needed.
