TLS and __cxa_atexit() for RTEMS

[Sebastian Huber]

Hello,

the GCC implementation for destruction of thread-local objects relies on the 
presence of a __cxa_atexit() support.  Newlib provides this function.  It is 
also used on ARM EABI.  Is there a specific reason why this is not the default 
for all RTEMS targets or in other words why don't we have in gcc/config.gcc:

*-*-rtems*)
   [...]
   default_use_cxa_atexit=yes
   ;;
