Hello, Lauro.> I know there is a bug report about TLS (PR941). Is there someone > implementing TLS in LLVM and llvm-gcc? If not, I will implement this.It's in my todo list. But I don't know, when I will have a chance to start working. Adding TLS support seems to be tricky, since there are 4 different TLS "models" with different "assumptions". -- With best regards, Anton Korobeynikov.
