ABI and complex integral types

[Eric Botcazou]

Hi,

What is the common ABI convention (if any) for passing complex integral 
arguments by value to functions? Structure-like or list-like?

Currently the SPARC64 port uses a mix of both :-) For example, in order to 
pass a complex int (2 x 32-bit), it reserves two 64-bit slots but loads the 
whole argument in the first slot. So we end up with holes in the arguments 
array (which incidentally fools the va_list handling code).
