--- Comment #2 from Martin Liška <marxin at gcc dot gnu.org> --- Created attachment 36655 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=36655&action=edit Suggested patch Hello. Following patch should correctly force calculation of hash values that are different for all variables and no O(n^2) comparison is processed. Could you Neil test the patch on the whole source file before I'm going to send the patch to mailing list? Thanks, Martin
