I tried an emerge -ev world yesterday (on a box with a total about 1100 emergeed packages), so far only had compiling trouble with gst-pluings-ffmpeg (gcc4.7.0 bug including patch is on b.g.o[1], so was easy to solve) and firefox 12. All of KDE 4.8.3 and libreoffice did emerge nicely. Though i did not test the results yet. SaCu [1] https://bugs.gentoo.org/show_bug.cgi?id=407741 |

I will give it a try on one of my machines tonight. In gentoo-ricer-terms: did you notice any improvements? ;-) Stefan |

Since you didn't mention any specific workloads (like audio or video compression), I assume you're a typical desktop user (internet browsing, email, watching movies, listening to music, etc.) There will be no differences in performance with GCC 4.7. |

There are some packages which seem to break: - - firefox and thunderbird, if I remember correctly - - chromium (theres an open bug on bgo) - - hardened-sources: the neccessary gcc-plugins don't work because they can't find the right symbols because gcc-4.7 is normally compiled with g++ which mangles the symbols. Don't know how to work around that, though it seems to be possible to compile gcc-4.7 with gcc - I just don't know how For all packages which break it's possible to switch to your old gcc-version (unless you uninstall it).

Is it faster / smarter ? Does it shows more warnings or produce faster / smaller code or something ? |
