There is a discrepancy when passing empty struct in C++ on x86-64 between GCC and Clang:
https://groups.google.com/forum/#!topic/x86-64-abi/EZzVyvSxUx4 An empty struct of size 1 byte is classified as NO_CLASS. GCC uses an eight byte slot to pass it on stack and returns it in EAX while Clang just skips it. Is this possible to pass/return empty struct for C++ the same way as for C? -- H.J.
