But I think there's a problem with the implementation in compiler_rt. Clang generates functions calls to compiler_rt if it can't inline __c11_atomic_* (e.g. if the architecture only guarantees atomicity if an object is properly aligned and a given object isn't aligned) so how can compiler_rt then use __c11_atomic_*? -- You are receiving this mail because: You are the assignee for the bug.home | help
