I guess your testbed is an i386 platform. However, what I see here is different.
Testbed i686: Ubuntu 18.04.4 LTS/GCC 8.3/ Clang 9.0.0-2
Both Clang and GCC for i686 generate code with xadd for these two cases.
Testbed i386: Ubuntu 16.04 LTS (Installed libatomic)/GCC 5.4.0/ Clang 4.0.0
GCC will generate code with cmpxchng8b for both cases.
Clang generated code emits a function call for both cases.
Thanks,
Phil
