+ * 1*4 byte   holding a pointer to space for aggregate returns (the space is
+ *            always reserved, regardless whether we have an aggregate return
+ *            or not)
+ * 6*4 bytes  Space for spilling parameters 0-5. For the cases when someone
+ *            takes the address of a parameter. I guess this is also there so
+ *            the implementation of va_args gets easier -> We can simply store
+ *            param 0-5 in this spaces and then handle va_next by simply
