Hi, David
The front-end drivers use -pthread and that often adds -lpthread. But
-pthread is not passed to cc1, etc.
I am not certain if there is a way for the compiler to ascertain that
it is being invoked to compile a file intended for a multi-threaded
application. It knows bout OpenMP and __thr
Is there a way to tell if the program is going to be multi-threaded?
If not, it might be useful to introduce a compiler option such as -fmt
which also enables -lpthread. Using tricks like weakrefs can
introduce unnecessary runtime overhead.

Some helper functions for TLS on AIX and Solaris 9 only are provided
by libpthread. Promoting ic related variables to TLS breaks profiling
of non-pthread appications. I completely agre
