afaik, there is C ABI, that defines how to pass and return parameters
of simple types, it's common for all compilers supporting so-called
"cdecl" on any architecture (x86, x86-64, ppc, so on). C ABI doesn't
define how to pass structures, so we can't generate universal
assembler code for this example - it depends on what compiler we want
to interact to
moreover, even for pointers-to-structures, there is no definitive
layout due to packing problem
OTOH, we could try to use gcc agreements
