This should be documented in the ABI description and of course could be 
different for the different calling conventions (Register, STDCALL, 
...). If the ABI defines that GS can be modified by the callee FP should 
of course save it on the stack before calling and restore it afterwards. 
Seems like "Standard" to me.
