Getting a broken program when the -funroll-loops flag is set (gcc linaro arm)

by Mickey Iluz

Hi, I've encountered a case where gcc produces a broken program: a branch that should never be taken is taken, and wrong values are written to memory (and printed out). The code is fairly ordinary and small. It can be seen here: http://pastebin.com/0Hspz8mw This happens when -funroll-loops flag is used in conjunction with -O2 or -O3. It doesn't seem to happen when it is used with -O1. Another few things that influences the program flow from from incorrect to correct run (gives expected outpus) are: - Adding/removing printf's inside the inner loop - Changing the order of the expressions in the "if" clause. i.e. from this: if ((y < mu) || (y >= H - md) || (x < ml) || (x >= W - mr)) to this: if ((x < ml) || (y >= H - md) || (y < mu) || (x >= W - mr)) - Assigning ml inside f() to the same value (3) it's getting from the function arguments. All of these shouldn't change how the program behaves but it does. I compiled this with two different compilers/environments: 1. g++ (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3, running on 3.2.1-42-linaro-lt-mx6 (native compilation on the ARM board) Compilation command: g++ -march=armv7-a -mfpu=neon -mfloat-abi=hard -mtune=cortex-a9 -O3 -std=c++0x -funroll-loops -o test_bug_sa_loops_linaro test_bug.cxx 2. arm-fsl-linux-gnueabi-g++ (Freescale MAD -- Linaro 2011.07 -- Built at 2011/08/10 09:20) 4.6.2 20110630 (prerelease) Running on a freescale LTIB built linux (3.0.15-1359-g1b64ead) Compilation command: arm-fsl-linux-gnueabi-g++ -march=armv7-a -mfpu=neon -mfloat-abi=hard -mtune=cortex-a9 -O3 -std=c++0x -funroll-loops -o test_bug_sa_loops test_bug.cxx In all the variations I tried it seems that -funroll-loops is critical for this problem to appear. I'd be glad to hear some comments on this. Mickey. This mail was sent via Mail-SeCure system.

I've posted the lines at http://lists.linaro.org/pipermail/linaro-toolchain/2012-October/002913.html Good point. There's nothing obvious in the list. Ubuntu explicitly adds --enable-checking=release but it's the default for release branches like ours. I can reproduce the slowdown in a smaller testcase. Compiling pcre with -O3 -mfpu=neon -march=armv7-a -mtune=cortex-a8 takes 18.8 s for the Ubuntu Precise 4.6 compiler, 17.8 s for the Ubuntu Quantal 4.7 compiler, and 41.2 s for the Linaro 4.7 2012.10 build. I've logged LP: #1077739 to track. I'll spin a --enable-checking=release build just to check. > The above lines do not work for me, the last line misses a changelog file: > > # dpkg-buildpackage -uc -us -b > tail: cannot open `debian/changelog' for reading: No such file or directory > dpkg-buildpackage: error: tail of debian/changelog gave error exit status 1 Yip, you need to change to the just-extracted source directory first. -- Michael

(/usr/lib/libnfc-common-lib.so.1: unexpected reloc type 0x03) Hi there. I don't know the cause but I'm suspicious of a few things. Could you try the following builds? The most likely: * Without -mapcs * Without -fstack-protector --param=ssp-buffer-size=4 Less likely: * Without -fno-common * With -fPIC instead of -fpic (should make no difference on ARM) Could you also send through the linker command line?

unexpected reloc type 0x03 error with gcc-4.6.4 (2012.10 version)

by Kyungmin Park

Hi Michael, Recently I tested the linaro toolchain gcc-4.6 version and try to build our codes. it's okay to compile the codes, but when launching the binary it occures following messages. /usr/lib/libnfc-common-lib.so.1: unexpected reloc type 0x03 I tested it both "hard float" and "soft float". the result is same. do you have any clues? Test environment: toolchain: gcc-4.6.4 (2012.10 version) soft float option. Thank you, Kyungmin Park

[ACTIVITY] report week 45

by Peter Maydell

* Attended LinuxCon Europe / ELC-Europe / QEMU Summit / KVM Forum (an overlapping set of conferences across a week in Barcelona) LCE/ELC: brief summary of interesting sessions (I've only listed ones which seem most relevant to ARM just to keep the length of this report down): * "Devicetree and its stumbling blocks" -- a view from a kernel developer perspective of some of the issues with doing platform data to dt conversions: (a) dt is supposedly OS independent and an external ABI, implying more need for cleanliness and long term supportable interfaces. (b) conversions imply a need to generalise bindings to be usable across many devices (c) what do we do about configuration / policy choices? My take is that the kernel folks are tying themselves in knots to try to preserve the (somewhat fictional in practice) idea that any kernel will work with any older device tree blob and they'd find it easier if they declared an amnesty for breaking changes before some deadline date... * Developing and testing industrial hardware with QEMU Rather than developing/testing sw against expensive/limited availability hw, use a model -- easier automation, ability to simulate error conditions, etc. If your hardware is basically a PCI card in an x86 box QEMU's fairly easy to use for this. * UEFI Secure Boot A summary of the current status of UEFI Secure Boot: it's mandatory for Win8 hardware; Linux implication is that we need to be able to maintain simple "out of box boot off distro CD"; optionally, if we have end-to-end signed binaries we have access to environments which will end up mandating it (read: government). Fortunately people have come together to tackle this and it looks like we're in good shape. http://mjg59.dreamwidth.org/18945.html is a good summary. * Kernel report by Jonathon Corbet ARM featured fairly prominently in this stats-driven roundup: 64-bit ARM support was first listed bullet point for 3.7 features Pointed out that Linaro and other embedded-ARM kernel contributions are notably up, ARM mess has been cleaned up. KVM Forum: * Concurrency in QEMU Plans for splitting QEMU's "big lock" into finer grained mutexes; should improve I/O scalability for KVM guests and realtime guest latency. However some tricky locking design issues to be solved. I am as usual sticking my oar in occasionally to remind people that the world is not solely x86-and-PCI... * qtest A summary of QEMU's new qtest framework, how it works and how to write tests. We're going to start insisting on test cases for new patches, so I need to write some basic tests for a few ARM devices so I know how it works :-) * ARM Virtualization for the Masses Christoffer Dall's talk introducing the ARM virt. extensions and KVM work. Well received, various questions afterwards (some elements of "why doesn't this work the way the x86 stuff does", also lots of "does this work on the Samsung/Google Chromebook" :-)) QEMU Summit: * This was an invite-only afternoon with perhaps 20 or so of the main QEMU contributors; broadly focused on "process" issues like release management, patch flow and security bug handling. Productive session; minutes should be available on the QEMU mailing list shortly. This is likely to be repeated next year. Informal discussions (IME the most important and worthwhile part): * virtio related : ran through current status of virtio-mmio patches with Anthony Liguori and Alex Graf, confirmed what changes we need to make and what the next steps with this should be. Some enthusiasm for getting this patchset in in the early part of the QEMU 1.4 release if we can. I'm really happy that we've unblocked this bit of work which had stalled slightly trying to figure out the right approach. Long term we will probably end up using virtio-pci on ARM but this is really dependent on hardware with good PCI support appearing. * SystemC : the upstream community is not currently interested in SystemC support, but there is some work on the QEMU core which would be a useful cleanup for QEMU itself and also useful for the SystemC folk. I'm hopeful that this might help to bring people working with QEMU in SystemC closer to the "QEMU upstream" community and mailing list, but it will be a gradual process both socially and technically if it does happen. * an informal enquiry about whether system emulation of virt. mode in ARM was planned or how much work it would be * in-kernel-irqchip: common ABI cross architecture the current ABI is a bit x86-specific, useful discussion about what POWER/S390/ARM would need. There will probably be some more ioctls coming along but the good news is that what the KVM ARM patches have currently fits into the proposals with only a very trivial tweak; we can add support for the new ioctls later if they are useful for us. -- PMM

Compilation speed of Linaro's gcc compared to e.g. Ubuntu's version

by "Frank Müller"

Dear all, we have an ARM Cortex-A8 board where we are running our application. I am in charge of maintaining the Linux on it and the toolchain/SDK setup. So far we've been running Poky/OpenEmbedded and using the cross compiler that came about during the compilation. For easier maintenance, we are now switching to Linaro. The image is set up and I can compile, however I notice a peculiar fact: the binary distribution of Linaro's gcc (https://launchpad.net/linaro-toolchain-binaries/trunk/2012.10/+download/gcc…) has a significantly larger compilation speed than a version of arm-linux-gnueabihf-gcc that is shipping with Ubuntu. In our particular case, using Ubuntu's version it takes less than 6 minutes to compile our software, but 10 minutes when we use Linaro's version. The makefiles and source are exactly the same, only the compiler is different. I also tried an older version (4.6) of Linaro's gcc to match the Ubuntu one (tested the 12.04 shipped version), with no significant difference. Compiler flags for the system are -march=armv7-a -mtune=cortex-a8 -mfpu=neon -mfloat-abi=hard Running with -ftime-report, most of the additional time seems to be spent in the parser. Adding -fno-graphite-identity -fno-graphite for Linaro's gcc did not make a difference. I believe I tried to use crosstool-ng to make my own version, but I don't remember the results as this was over 7 weeks ago. I also did not have a chance to compare performance of the binaries. I do notice a difference in compilation sizes (4.8 MB for Ubuntu's 4.6 version, 4.1 MB for Linaro's 4.7 versions - can't test anything other right now). I would like to use Linaro's gcc as the crosscompiler for our project, as it is an easy setup. Repackaging Ubuntu's version is an option, though (some of the team do not use Ubuntu, plus I'd like everybody to use EXACTLY the same version of the crosscompiler). So there is no real "problem" for me, per se, but I am extremely curious as to what is going on here. It seems that Linaro's gcc has additional patches or maybe just different default settings that cause additional time to be spent in the parser. It would be interesting to know what exactly this is and whether/how it can be disabled in those cases where time of compilation is more important than e.g. performance gain. TIA for replying. Best Frank

Initial aarch64 plans

by Michael Hope

This is the first of a few Connect follow up emails. KVM and Cortex-A15 tuning are to come. Matt and I have entered the initial aarch64 blueprints. These are part of the bootstrap that clear the way for us and the community to port packages on top. The high priority ones are: * Add support for AArch64 to Boehm GC[1] * Add support for GProf to AArch64 backend of GCC[2] After those we have: * Add IFUNC support for AArch64[3] * AArch64 GCC support for Stack Protection[4] All are linked off the parent blueprint at: https://launchpad.net/gcc-linaro/+spec/aarch64-gcc-initial-meta and we'll add more there as time goes by. The plan is to commit to the first two and do them this iteration. The latter two aren't critical and will be done as part of our general work. -- Michael [1] https://launchpad.net/linaro-toolchain-misc/+spec/aarch64-boehm-gc [2] https://launchpad.net/gcc-linaro/+spec/aarch64-gcc-gprof-support [3] https://launchpad.net/binutils-linaro/+spec/aarch64-gcc-ifunc [4] https://launchpad.net/gcc-linaro/+spec/aarch64-gcc-ssp-support

by Peter Maydell

* Attended Linaro Connect; notable sessions: + Ubuntu plans for QEMU for Ringtail release = upstream qemu has merged qemu-kvm back in so Ubuntu will switch to qemu from qemu-kvm for x86 = also makes sense now to use upstream qemu for all archs (following Debian) rather than using qemu-linaro for non-x86: reasons for using q-l in Ubuntu now mostly fixed (ie upstream ARM support no longer dire). Ubuntu will carry omap3 patches to avoid dropping that feature in the changeover = makes sense for Linaro too as we now have an automated package-to-PPA setup for people who need bleeding-edge and also will want Ubuntu to transition to a more stably released and supported QEMU codebase to use for KVM-on-ARM-servers + KVM Testing plans = worked through a list of things that would be nice to test; useful feedback from people in the session about what matters. Missing: specific commitment by anybody to write tests :-) + various informal discussions about possibilities for v8 QEMU * this week: at LinuxCon Europe / ELC-Europe / KVM-Forum / QEMU Summit -- PMM

Some ugly patches for gcc-linaro on Android

Hi, here's some patches for gcc-linaro to make it work with --host=arm-linux-androideabi They're the quick and dirty thing to do and look like they could have been written by Microsoft, needed something working in time for Connect ;) gcc-4.7-android-workarounds.patch: Workarounds for things that go wrong, but where the true cause is yet to be determined (e.g. why would configure think we have fread_unlocked and friends when we don't?) gcc-4.7-libitm-android.patch: Workaround for Bionic not knowing Elf32_auxv_t gcc-4.7-no-unneeded-multilib.patch: Get the multilib config in sync with regular Linux gcc-4.7-stlport.patch: Use stlport instead of libstdc++ (yes, this sucks - but it's what Android decided to do). Still needs to link libstdc++ because Bionic contains a libstdc++.so (but it's more like a libsupc++ - no STL there, but needed for stlport to work). ttyl bero
