--- Comment #5 from Jan Hubicka <hubicka at gcc dot gnu.org> --- as g:132d01d96ea9d617aaffdd5dfba3284a8958e529 I have committed the patch that enables ipa-cp to clone over edges which are !maybe_hot_p(). This improves x264 with FDO by 7.8% and exchange by 3.3% It causes quite noticeable code size bloat with -fprofile-use https://lnt.opensuse.org/db_default/v4/SPEC/64577 (O3) i.e. 6.4% on GCC binary https://lnt.opensuse.org/db_default/v4/SPEC/64571 (O2) While there are no performance improvements at -O2. This is bit odd, since we should clone only if we know that we are going to improve something in So the heuristics needs work...
