Hi,
This patch partly fixes PR bootstrap/63995 by avoiding duplicating static
bounds vars. With this fix bootstrap still fails at stage 2 and 3 comparison.
Bootstrapped and checked on x86_64-unknown-linux-gnu. OK for trunk?
Thanks,
Ilya

Hi,
This patch makes optimization for bounds lifetime reduction to ignore debug

Hi,
This patch fixes ICE in chkp_find_bound_slots_1 by checking for non constant
values in array domain. Bootstrapped on x86_64-unknown-linux-gnu with Ada.
gnat.dg/derived_aggregate.adb is a new pass. OK for trunk?
