The patch was not ready until almost a week after 3.5 branched. The PIC diff was ready earlier. Please don't be insulting; several of us working on the PowerPC backend discussed this on IRC, with Justin (the author of the patch), and other members of the community. To be clear, my understanding is that even with the TLS patch applied, we cannot self-host on ppc32/ELF. Given the continuing efforts of Justin and others over the next few months, I'm looking forward to Clang/LLVM 3.6 being a viable option for ppc32/ELF.
