<http://lists.debian.org/debian-68k/2008/02/msg00212.html> and
<http://lists.debian.org/debian-68k/2008/03/msg00008.html> still apply: we
expect the implementations to be complete, validated and contributed some
time this year. (Note that the binutils multi-GOT patch, a prerequisite
for the binutils TLS work because both involve major changes to the same
areas in BFD, has been posted to the binutils list and revised in response
to reviewer comments. The plan is for the binutils TLS support to be
developed based on FSF binutils HEAD once the multi-GOT support is there -
so the multi-GOT patch is in that way progress towards TLS (and of course
there will be multi-GOT support for the new TLS relocations).) Based on
previous experience implementing TLS and NPTL for other targets, I expect
them to be ready for the end of Stage 2 for GCC 4.4 development (August by
current plans), but even if the GCC patch isn't ready then to go in FSF
GCC 4.4 I expect we'll still post it as soon as it's ready to make it
available for inclusion in distributor versions of 4.4 and backporting to
older compiler versions if desired.
