GCC 4.6.2 with the default USE flags fails to build on a Pentium III. The (first) error is a failure of the stage 2/3 comparison of varasm.o, but if stage3-gcc/varasm.o is copied to stage2-gcc/varasm.o and the compilation continued, FWIW there is a further error with the log entry: ... make[4]: Entering directory `/var/tmp/portage/sys-devel/gcc-4.6.3/work/build/prev-gcc' make[4]: *** No rule to make target `real-install-headers-tar'. Stop. make[4]: Leaving directory `/var/tmp/portage/sys-devel/gcc-4.6.3/work/build/prev-gcc' ... This doesn't at the moment concern me. I've repeated this build three or four times now with different flags, and it's failed every time. Moving to -march=native, BTW, produces a different failure, but still fails. The same problem occurs with GCC 4.6.3 The standard GCC package from gnu.org compiles in the usual out-of-tree build without problems. If there's some configuration change I could make to get it to compile, I'd be grateful for advice. The builds were in a chroot using the most recent Stage 3 and portage tree, and no other software was running. Attached (if I've got attachments right) are all the various logs, the emerge data, and the two versions of varasm.o C W Rose Reproducible: Always Steps to Reproduce: 1. Unmask gcc-4.6.2 2. Run "emerge sys-devel/gcc" 3. Wait Actual Results: The emerge failed partway through the build.

Created attachment 308289 [details] Various logs dealing with a GCC 4.6.2 build failure on Pentium III
It's happening on GCC 4.6.3, too. I tried to compile a new system and it constantly gives me this issue on my dual P3.
Similar issue with 4.6.3 on "Intel(R) Pentium(R) M processor 1.60GHz" and CFLAGS="-O2 -mtune=pentium-m -pipe -ggdb"
The same issue with GCC-4.6.3 on "Intel(R) Pentium(R) M processor 1.50GHz". CFLAGS="-O2 -march=pentium-m -pipe -fomit-frame-pointer"
Ok. I just compiled it on a dual Xeon 2.4GHz (Poweredge 1750) and it didn't have the issue. I tried it again on my dual P3 and it crashed in the same spot. What's broken with the P3?

Can one of you guys open an upstream bug report? I don't know what info they'll need and I'm not in a position to provide it.

I'm getting the same failure with GCC 4.6.3 on Pentium III. How best to patch GCC with the fix provided?
There's no way we're backporting a patch that size. Try EXTRA_ECONF="--disable-frame-pointer". Or just use 4.5. It's not as if you're going to be missing out on any great pentium 3 related features.
Does anyone know when the next working version of GCC will be available (for Pentium III, obviously). Will
It seems on the forums someone mentioned temporarily changing CFLAGS to i686 can get the compiler built. I may try this one out on my P3.

Workaround: threw Pentium III computer in dumpster.

Confirming same symptom with sys-devel/gcc-4.6.3 on alpha.
Created attachment 333058 [details] log file of problems during patch application in gcc-4.6.3 Not sure wether this is completely resolved yet; I experience the same issue and noticed problems during patch application (see attachment)
Not a biggie. We can just change the "architectures" entries on the Gentoo website, distrowatch, etc., to add "except Pentium III".
and except pentium-m :(

Nobody forces you to use 4.6.x on those architectures. It's still ~x86 for a reason. Same goes for 4.7.x, where this is fixed by upstream. If you need to use newer version of gcc, use the latter. Spreading FUD here won't speed up the backporting. If you really want to express your disappointment please use upstream bug [1]. If they notice that many people are interested in this issue being fixed they *might* be more willing to the job.

CFLAGS = i686 works fine for me. I don't often emerge gcc anyway Will
Can you just filter these flags (and replace march with i686) for affected ebuilds as a workaround?

I may try this one out on my P3. > > Confirmed, using CFLAGS = i686 works on my P3, now have 4.6.3 installed. Doesn't this mean you have a BROKEN gcc installed? At least when using -march=pentium3 again? (In reply to comment #28) > It's still ~x86 for a reason. It is not any longer, although this bug is not yet fixed. I just stumbled over it on a pentium-m notebook after 4.6.3 was stabilized on x86. I will mask it manually.
(In reply to comment #30) > Can you just filter these flags (and replace march with i686) for affected > ebuilds as a workaround? Just read comment #18. There is no urgent need to update gcc on a pentium3 or pentium-m machine dating back to 2006 or earlier.
Adding -fno-omit-frame-pointer to CFLAGS also helps.
(In reply to comment #24) > Confirming same symptom with sys-devel/gcc-4.6.3 on alpha. Probably the source of the problem here is different from the one on alpha, i've filed bug 451680 for this
Confirmed on Pentium II too :] Linux ServX 2.6.24-gentoo-r1-ServX #2 Sun Apr 20 02:53:51 CEST 2008 i686 Pentium II (Klamath) GenuineIntel GNU/Linux CFLAGS="-march=pentium2 -O3 -pipe -fomit-frame-pointer -m32"
(In reply to comment #23) >> Try EXTRA_ECONF="--disable-frame-pointer". > EXTRA_ECONF="--disable-frame-pointer" emerge -a1v gcc didn't help, same problem. I think that should be: EXTRA_ECONF="--enable-frame-pointer"
The same thing is happening to me with march=btver1. I was able to compile gcc 4.6.3 with march=nocona though.
There's a request for testing HEAD of gcc-4.6 branch on upstream bug. If any of you, who has PIII could verify it, we'd be grateful. Should you have problems with compiling from source there's gcc-4.6.4_pre9999.ebuild in toolchain overlay. TIA!
I wouldn't like to say whether these two problems are in fact the same, but there are suspicious similarities... see bug https://bugs.gentoo.org/show_bug.cgi?id=450964 In short, I can confirm that leaving out the -march option will produce a usable compiler on PIII systems.
Created attachment 338976 [details] failed build logs - gcc-4.6.4_pre9999 on pentium M
(In reply to comment #38) > problems with compiling from source there's gcc-4.6.4_pre9999.ebuild in > toolchain overlay. TIA! FWIW I have a pentium-M (after all, pretty much a PIII) and I'm seeing the same bootstrap comparison failures, so a gave the above ebuild a go... still fails (attachment 338976 [details])
Just hit this on a PIII box. I'm aware this is an upstream bug, but maybe GCC 4.6 should be marked ~x86 until this is fixed? For the record, the build worked with CFLAGS="-O2 -march=i686 -fomit-frame-pointer -pipe" (my usual setting, with which the build failed, is CFLAGS="-O2 -march=pentium3 -fomit-frame-pointer -pipe").
I just ran in to this bug and spent lots of time wondering what was wrong. Could some warning be added to the package that would trigger on march=pentium3 so M?
Confirm this bug affects not only march, but also for specific tuning: march=i686 mtune=pentium-m
Since this won't be fixed upstream (the 4.6 branch is now closed) we'll add a workaround. Sorry about the wait.
