--- Comment #15 from Konstantin Serebryany <konstantin.s.serebryany at gmail dot com> 2012-11-19 09:03:35 UTC --- You are right that "-fPIC -ftls-model=initial-exec" does not affect performance if we link libtsan statically (I checked). As you say, the linker nukes one of the loads. But if we link libtsan.so dynamically, we still get both sources of overhead.
