Are you are talking about passing arguments to a function? PPC32 passes long long arguments in two registers in the order you would expect (hi, lo), BUT you have to use an odd/even register pair. In other words, if you have a function like this: int foo(int a, long long b) then a will be passed in r3 and b will be passed in r5 and r6, and r4 will be unused.
