--- 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
