ABI for i128 on x86-32?

Hello, Dan

Does anyone know of any precedent for handling i128 in the
calling convention on x86-32?

Never seen this 'in wild' (pure integer case).

I'm trying to write a testcase that returns an i128 value,
and LLVM currently has only two 32-bit GPRs designated for
returning integer values on x86-32.

Can XMM registers be used for such things?
