--- Comment #1 from Uroš Bizjak <ubizjak at gmail dot com> --- I don't see problem here. There is no requirement that libatomic uses SSE instructions. Also, -mno-sse is not x86_64 ABI compliant, so all used libraries should use -mno-sse too. This is the same situation as compiling with -mno-sse and expecting that math library also doesn't use SSE instructions. So, corresponding libatomic (without SSE insns) should be provided in this case.
