Contrary to what is stated in the Registers part of Chapter 3 of the
System V Application Binary Interface PowerPC Processor Supplement there
are no values set in registers r3, r4, r5, r6 and r7. Instead the values

the stack. The value to be placed into register r7, the termination
function pointer is not passed to the process.
