The calling convention is implemented within gcc itself. gcc does not implement stdcall on ia64. I doubt that anybody does. It is much less interesting when most parameters are passed in registers. The ia64 ABI which gcc implements is documented here: http://www.intel.com/design/itanium/downloads/245370.htm Ian
