Commit 806dd0472f56 (Improve the thread support for VxWorks) introduced calls of (on vxworks 5 at least) non-existing __gthread_enter_tls_dtor_context/__gthread_leave_tls_dtor_context ; the code used to call __gthread_enter_tsd_dtor_context/__gthread_leave_tsd_dtor_context. Those are simply no-ops (we simply use the definitions which are provided in contrib/gthr_supp_vxw_5x.c), so we can fix this by nop'ing out VX_ENTER_TLS_DTOR/VX_LEAVE_TLS_DTOR for vxworks 5.x. --- libgcc/config/gthr-vxworks-tls.c | 5 +++++ 1 file changed, 5 insertions(+)
