We are currently working with Freescale's kernel engineers on finalizing the kernel interface for TLS and NPTL. We expect the toolchain and kernel implementations to be completed, and contributed to FSF binutils / FSF GCC / EGLIBC / kernel.org, some time this year. Obviously Debian would then need to backport patches to the relevant versions of the various components, although it's likely we will do a backport to GCC 4.3 for our own use at some point. The binutils changes are likely to overlap heavily with changes for multi-GOT support for ColdFire we have completed and will be contributing before starting the TLS work, so backporting TLS without also backporting multi-GOT may be tricky. (Multi-GOT addresses the issue mentioned in the ABI proposal of memory address offsets on ColdFire being limited to 16 bits while avoiding the larger and slower code sequences mentioned to use 32-bit offsets there. Either multi-GOT, or GCC support for generating such larger code sequences (also implemented and to be contributed), is needed to build some large pieces of software such as PHP for ColdFire.) -- Joseph S.
