MThere are performance implications of doing so. One way would be to add facility to insert new variables into emutls late (it is probably doable). Other easy way around would be to add gcov function to set both pointers to proper values and do it as function call. I am not sure if this is feasible performance wise - the counter is in TLS just to avoid too many colisions. Generally profiling should work resonably well even without TLS for that. > > #if defined(HAVE_CC_TLS) && !defined (USE_EMUTLS) > > does, indeed, work. If you do have chance to commit it, consider the patch preapproved. I will be offline during the afternoon. Honza
