It's a change in ABI for the RTEMS platform but it certainly needs a
documentation update in the release notes . Also, is it necessary that
you need this in for GCC-7 or can you wait for stage-1 since we are in
regression fixes mode ?

For RTEMS, ABI changes are not really critical. I would like to get this 
into GCC 6.4. For GCC 7 its not urgent.
