 \item stack always aligned to 8 bytes

+\item 64 bit arguments are passed like two consecutive \textless=\ 32 bit values
 \item minimum stack size is 64 bytes, b/c stack pointer must always point at enough space to store all \%i* and \%l* registers, used when running out of register windows
 \item if needed, register spill area is adjacent to parameters
-\item results are expected by caller to be returned in \%o0\%o1 (after reg window restore, meaning callee writes to \%i0\%i1) for integers, \%f0/\%f1 for floats, and for structs/unions a pointer to them is used as a hidden stack parameter (see below)
