For more in-depth information on different ABIs (Clang isn't covered but follows GCC pretty closely), see Manual #5 [1] of Agner Fog's optimization manuals.

Nice recommendation. Someone mentioned it as well on proggit: http://www.reddit.com/r/programming/comments/24gpqp/lets_wri...

Any ABI differences between Clang and GCC for externally visible functions is a bug. The system defines that ABI (SysV for Mac and Linux x86_64). Internally visible functions can use different ABIs that allow the compiler to perform more aggressive optimizations.
