That will probably break small structure return.

See

    case FFI_TYPE_STRUCT:
#ifndef X86
      /* ??? This should be a different ABI rather than an ifdef.  */
      if (cif->rtype->size == 1)
        flags = X86_RET_STRUCT_1B;
      else if (cif->rtype->size == 2)
        flags = X86_RET_STRUCT_2B;
      else if (cif->rtype->size == 4)
        flags = X86_RET_INT32;
      else if (cif->rtype->size == 8)
        flags = X86_RET_INT64;
      else
#endif
