The proposed TLS ABI for ColdFire and m68k, including the required kernel interfaces, is below; any comments?Out of curiosity, has any progress been made? I think we're going to need to update glibc rather soonish and it would be nice to have TLS and NTPL, otherwise it's going to get ugly.<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.
Thanks for the update. :) -- Stephen R. Marenka If life's not fun, you're not doing it right! <stephen@xxxxxxxxxxx>
