--- Comment #3 from Martin Sebor <msebor at gcc dot gnu.org> ---
The MEM_REF formatting done by the C and C++ pretty-printers is very basic and
doesn't always result in useful output (usually in the most interesting cases).

I posted a patch some time ago to improve it for C++ (as part of fix for an ICE
reported in pr95768):
https://gcc.gnu.org/pipermail/gcc-patches/2020-June/548698.html

Richi had some concerns with it but I think it's a significant improvement
despite them.  I plan to extend the C++-only patch to C and post it again at
some point when I'm done with stage 1 work.  If it's approved it should be
straightforward to use the same approach in the D front end (in fact, all front
ends should share the same code for this).
