+ * Sparc ABI requires some space which is always available at the top of
+ * the stack. It contains:
+ * 16*4 bytes space for spilling the register window
+ * 1*4 byte   holding a pointer to space for agregate returns (the space is
+ *            always reserved, regardless wether we have an agregate return
+ *            or not)
+ * 6*4 bytes  Space for spilling parameters 0-5. For the cases when someone
+ *            takes the adress 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
+ *            incrementing the stack pointer
