the state of amd64-TLS is this:
its basically implemented but there's a bug that lets only first program
run with TLS, all subsequent attempts to use TLS segfaults. I discussed this
with davidxu@ and he told me saw something similar which was caused by
reloading of %gs $somewhere. I digged through the sources and in
linux32_locore.s we reload it.. I am no expert with this so I'd like to
ask you for help and possible testing.
can you test p4 branch (which includes amd64-tls) with the %gs/%fs reloading
commented out in linux32_locore.s? and if that doesnt work look at the issue
(I guess you are fluent with amd64 internals).
thnx
