[PATCH] VAX libstdc++ common runtime - register used but not saved

Hello all,

I believe that I've found a problem in libstdc++ for VAX where, in the
__do_global_ctors_aux function, %r8 is used but not saved.  %r11, which
is saved, is not used.

I'd like to propose the following change against NetBSD 10.99.6 to
correct it.

Many thanks
kalvis
