--- Comment #6 from Roy Jacobson <roi.jacobson1 at gmail dot com> ---
We recently upgraded our toolchain from GCC9 to GCC11, and we're seeing
__tls_get_addr take up to 10% of total runtime under some workloads, where it
was 1-2% before.
It seems that some changes to the optimization passes in 10 or 11 have
significantly increased the impact of this problem.
