Do you mean adding TLS support for the old linuxthreads branch on x86? I can volunteer, but I may need someone more experienced to guide me. > > What could be the complexity/difficulty of implementing NPTL support on > > x86? > > > do you need TLS support or NPTL pthread library too? I only need TLS support. My program crashes when encountering variables declared with __thread. And that has nothing to do with the threading implementation, but only with the TLS support it provides. Regards, Cristi -- Ing.
