> I think x86 lets you return in eax and edx, but only if you're returning a single 64-bit value, not a struct with 2 32-bits.

Depends entirely on the platform ABI. Under the OS X calling conventions 2x32b is returned in eax:edx (even if the 32b values are floats, which is annoying).

Ah, true. x86 ABIs are much less unified than x86-64 ones.
