I've been using 4.6.1 since just a few days after the ebuild was there. I have less trouble compiling or running stuff than ever before.
Yesterday I switched to 4.6.2 (which mostly was a bugfix release according to gcc.gnu.org) and as the ChangeLog stated, that -flto was usable for things like gcc itself or Firefox, I started to recompile several libs and important stuff. I see a lot of packages failing (pixman, xorg-server, ...) but much stuff works and doesn't make trouble (ffmpeg, vlc, mplayer, libpng, ...).
I'm using

Why do you put '-mmmx -msse -msse2 -msse3 -mssse3 -msse4 -msse4.1 -msse4.2' in even though you already use march=corei7 and mtune=corei7? They already do that don't they? |

I've just done that for completeness and 'ease'. Some packages like ie. media-plugins/caps-plugins or dev-lang/ocaml sometimes don't like some of these mmx flags and it's easier to comment them out once they're in the make.conf. I, moreover, generate the 'basic' basic flags by using
| Code: | | gcc -march=native -E -v - </dev/null 2>&1 | grep c1 |
and dynamically append the other stuff by mixing variables. It actually looks like this:
| Code: |
11 __GCC_CURRENT="-march=corei7 -mcx16 -msahf -mno-movbe -maes -mpclmul -mpopcnt -mno-abm -mno-lwp -mno-fma -mno-fma4 -mno-xop -mno-bmi -mno-tbm -mno-avx -msse4.2 -msse4.1 --param l1-cache-size=32 --param l1-cache-line-size=64 --param l2-cache-size=4096 -mtune =corei7"
12 __GCC_COMMON="-funit-at-a-time -falign-functions -falign-jumps -falign-loops -falign-labels -ffunction-sections -fdata-sections -freorder-blocks -freorder-blocks-and-partition -freorder-functions -pipe -Wdisabled-optimization -ftracer -flto"

_GCC_CURRENT is the output for the current compiler being used (command above). With this, I can easily go down to compilation errors by uncommenting a CFLAGS variable. I've been doing this for years now and it's a solution I'm fine with when it comes to the need to use it.  |

just finished an emerge -e world on 1155 packages with gcc-4.6.2 on mostly stable AMD64. The following 4 packages had problems:
dev-lang/tcl-8.5.9: ICE with graphite flags enabled
dev-games/irrlicht-1.7.2 - patch from gamerlay for 4.6
net-libs/libtorrent-0.12.6 - unmask >=0.12.7
net-libs/xulrunner-1.9.2.20 - fix supposedly in 2.0.1 and awaiting backporting
| Code: |
CFLAGS="-O2 -march=native -mtune=native -pipe -ggdb -floop-interchange -floop-strip-mine -floop-block -fgraphite-identity"
LDFLAGS="-Wl,-O1 -Wl,--as-needed" |

Sorry for not reporting this in the bug. That was by no means intentional. Maybe call me a slacker

| Is anyone else running a gcc-4.6 compiled compiz? I just tried it, and it had a weird where it sometimes wouldn't give focus to a firefox window. Recompiled with 4.5 and everything seems to be fine now. |

Sorry for being snarky. Can you add your emerge --info and build log to the bug? Did you run grub-install after grub was built w/ 4.6, and if so did you get the "Mismatched or corrupt version" error or did it install but just not boot?

I have since upgraded to libjpeg-turbo thank you to ssuominen
If libjpeg-turbo is the default should they not mask jpeg-8b ? |

Problem is after I encountered that problem and got the machine finally back to booting I reverted gcc back to 4.5.3 and recompiled the whole machine with it.
Before I do this kind of adventure again I will first give one of my Gentoo-VMs a shot with gcc-4.6. But I will try to reproduce the problem there and will add the needed information to the bug report.
