--- Comment #4 from Martin Jambor <jamborm at gcc dot gnu.org> ---
I have proposed the following patches to address this on trunk.  The
testcase from comment #3 can be fixed with
https://gcc.gnu.org/ml/gcc-patches/2019-12/msg01183.html

The original testcase however needs also propagation from LHSs to RHSs
posted in https://gcc.gnu.org/ml/gcc-patches/2019-12/msg01184.html

Both patches require a small fix posted in
