[PATCH] D18095: Add __attribute__((linkonce_odr_linkage))

[Yaxun Liu via cfe-commits]

My last example is not proper. In real cases, the functions are overridden by functions with the same name and semantics but optimized for speed.

Besides, we want unused library functions in lib_common.ll and lib_opt.ll to be dropped, weak attribute does not achieve that.
