Subject: [Bug debug/64817] [5 Regression] compilation hangs at -O3 with -g enabled on x86_64-linux-gnu

--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Alex mentioned this is related to PR48866 and it is also related to PR56510. 
Since the latter, we actually break too complex debug insn expressions into
simpler ones (with maximum depth of 4), and it would do its job in this case
too, but the problem is that already the simplify_gen_* has the undesirable
complexity on the expressions.
