--- Comment #6 from Martin Liška <marxin at gcc dot gnu.org> ---
Problem is that IPA ICF contains compare_operand that is called recursively and
handles all tree types. Richard correctly pointed that we should split the
method to memory-related operand comparison and the rest (declarations,..).

I hope I can send the path on Monday-Tuesday next week.

Thanks,
Martin

--- Comment #4 from Martin Liška <marxin at gcc dot gnu.org> ---
Can you please check if the issue still persists?
I would appreciate further information related to PR, or do we have any GCC fam
machine I can debug it?

Thanks,
Martin
