I don't think this is going to change, sorry. I even have plans to make GCC always use a 128 byte stack frame unless varargs are being used, via a special GCC command line option like -mkernel or similar. There is no reason to pop arguments into that argument save area in the stack frame, unless varargs are being used. This is assuming I understand what you're talking about. :-) -- To unsubscribe from this list: send the line "unsubscribe sparclinux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
