Hi Julian, You can check how we did it for ARC. In a nutshell, you need to define HAVS_AS_TLS macro, you need to legitimize the new TLS address and calls. Please have a look in arc.cc and search for TLS, also use git blame to see the original patches. Of course, there are different ways to implement TLS, in ARC is the simplest solution. Also, u need to hack the assembler, linker and the OS for a full implementation.
