At current stage I think only a few arches have added TLS support. MIPS is definitely not one of them. Does anybody know about the current status, for MIPS and other arches? I think the ABI change and TLS support might take a long time to be ready. It appears meanwhile NPTL can run without TLS, but would need a couple of additional system calls that get and set thread local area. > I believe I heard reports that the glibc people were looking to > deprecate linuxthreads within a another release or two (but don't know > specifics or anything), so it sounds like NPTL should be something to > get working. > That surely puts some urgency on this matter. :) Jun
