Basically, yes. Of course, this only works if __thread is only used for
performance reasons, not for real thread local variables (which wouldn't
work on those architectures and older gcc's anyway). Maybe it would be
cleaner to use another name, which spells out what we are doing with it,
like ATTRIBUTE_USE_TLS_FOR_PERFORMANCE ;-)
