--- Comment #12 from Jan Hubicka <hubicka at gcc dot gnu.org> --- Created attachment 32442 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=32442&action=edit Better patch I am attaching more complete patch. There is quite bad wrong code bug in pure-const that updates declaration because it proves that one of inline clones is pure which does not imply that the offline copy is. The patch also need fix to tree-inline.c that I sent earlier and Richard requested a cleanup for http://gcc.gnu.org/ml/gcc-patches/2014-02/msg00134.html Will do that tomorrow.
