arm-eabi toolchain memcpy using hard float causing unaligned access

by Yupeng Chang

Hi Linaro Team, I'm currently using toolchain gcc-linaro-7.1.1-2017.08-x86_64_arm-eabi.tar.xz <https://releases.linaro.org/components/toolchain/binaries/latest/arm-eabi/g…> to develop my bera-metal programs. My compile option is "-marm -march=armv7-a -mtune=cortex-a9 -mlittle-endian -mfloat-abi=hard -mfpu=neon" I found an issue, when I use memcpy, and if the DEST or SOURCE address is not 4 bytes aligned, the system hangs. It seems that this toolchain doesn't support using hard float and NEON ? My question is does this toolchain support hard float and NEON in the newlib C library? If I want to use hard float and NEON, how can I do that? Your reply is more appreciated!!

ILP32 toolchain status update

by Maxim Kuvyrkov

Over the last couple of months arm64 community and us have tested various aspects of ILP32 toolchain and, while most of toolchain works as expected, several features are still missing. Most of the work left is on GDB side, especially using LP64 GDB to debug ILP32 applications. 1. [GCC] GCC sanitizers (ASAN, UBSAN) are not supported for ILP32. -- TCWG is working on implementing sanitizer support for ILP32. 2. [GLIBC] LP64 glibc libthread_db does not support ILP32. This causes failures when LP64 GDB is trying to debug ILP32 threaded application. It is expected by users to be able to use LP64 GDB to debug ILP32 applications (LP64 AArch64 GDB can successfully debug AArch32 applications already!). -- Steve, do you plan to work on adding libthread_db support for ILP32? 3. [GDB] Handle ILP32 siginfo layout. Kernel siginfo layout is different between LP64 and ILP32. 4. [GDB] Inferior call passing pointer argument. GDB may need update to handle 32-bit pointer vs 64-bit pointer. 5. Handle shared libraries. GDB needs to read a linked list out of the inferior, and that list is about the libraries loaded already. LP64 and ILP32 may have different layouts. 6. [GDB] GDB resolves ifunc functions, needs to read auxv (HWCAP) from the inferior. auxv is different on LP64 and ILP32. 7. [GDB] Gdbserver support for ILP32. -- Maxim Kuvyrkov www.linaro.org

ILP32 sysroot image

by Adhemerval Zanella

Hi all, I just upload an sysroot image for ILP32 meant to be used on both testing and development on dev-01.tcwglab [1]. It is based on out current ILP32 GCC 7 sysroot plus some tools and it is meant to easier development and testing. It should have all native required tools for GNU development: glibc 2.27 (arm/ilp32 branch) gcc 7.2.1 (linaro/gcc-7-branch) binutils 2.28.2 (linaro_binutils-2_28-branch) gmp 6.1.2 mpfr 3.1.6 mpc 1.0.3 coreutils 8.28 bash 4.4.12 gnumake 4.2 (plus a patch to fix glob usage on glibc 2.27) gawk 4.2 perl 5.26.1 textinfo 6.5 bison 3.0.3 m4 1.4.18 libtool 2.4.5 flex 2.6.4 tcl 8.6.7 expect 5.45.3 dejagnu 1.6 sed 4.4 diffutils 3.6 tar 1.29 gzip 1.8 finutils 4.6.0 I could build and check glibc and binutils and bootstrap gcc. The binutils and gcc tests are working (dejagnu/expect/tcl is installed). To actually get a working VMs to run ILP32 you need a kernel built with different branch than either canonical Linus tree or linux stable. Easier way is to use Maxim's automated script to start a qemu aarch64 instance on r1-a7: $ WORKSPACE=`pwd` bash -x ~maxim.kuvyrkov/src/jenkins-scripts/start-container-qemu.sh \ --weight 2 --node r1-a7 --arch arm64 --distro xenial --task test --prefix ilp32_ \ --kernel_url https://people.linaro.org/~maxim.kuvyrkov/norov-Image --initrd_url \ https://cloud-images.ubuntu.com/releases/16.04/release/unpacked/ubuntu-16.0… \ --session-name ilp32-$USER --newuser $USER --cp_file ~/.ssh/authorized_keys You can then log in the machine as usual ('ssh -P r1-a7.aus-colo') and download the sysroot from dev-01.tcwglab. Just uncompress it and issue the usual chroot command: $ mkdir aarch64-linux-gnu_ilp32/proc; sudo mount -t proc proc aarch64-linux-gnu_ilp32/proc $ mkdir aarch64-linux-gnu_ilp32/sys; sudo mount -t sysfs sys aarch64-linux-gnu_ilp32/sys $ mkdir aarch64-linux-gnu_ilp32/dev; sudo mount -o bind /dev aarch64-linux-gnu_ilp32/dev $ sudo chroot aarch64-linux-gnu_ilp32 A useful package missing is GDB and python, I plan to get them built and I will update the image on dev-01.tcwglab during this week.

[FYI] HCQC(HPC compiler quality checker) on GitHub

by Masaki Arai

Hi, I put HCQC(HPC compiler quality checker) on GitHub. URL: https://github.com/Linaro/hcqc Any comments or suggestions are very welcome. I am going to improve README.md overall and to add more test programs. I will also report the analysis results using HCQC on hpc-sig-devel. The attached PDF file was used to explain HCQC at HPC-SIG SC meeting(11/7). I think you can reproduce the results on this slide if you modify the following part of the configuration file: hcqc/config/clang-config.json "COMMAND" : "/usr/bin/clang", "VERSION" : "4.0.1", hcqc/config/gcc-config.json "COMMAND" : "/usr/bin/gcc-7", "VERSION" : "7.1.1", which you need to fix to suit your environment.

[ANNOUNCE] Linaro Binary Toolchain Release-Candidate GCC 7.2-2017.11-rc1

by Przemyslaw Wirkus

The Linaro Binary Toolchain ============================ The Linaro GCC 7.2-2017.11-rc1 Release-Candidate is now available. *Notice*: GCC 7.1 ABI change for arm*-*-* targets, and note for aarch64*-*-* targets >From GCC 7.1 release notes: On ARM targets (arm*-*-*), a bug introduced in GCC 5 that affects conformance to the procedure call standard (AAPCS) has been fixed. The bug affects some C++ code where class objects are passed by value to functions and could result in incorrect or inconsistent code being generated. This is an ABI change. If the option -Wpsabi is enabled (on by default) the compiler will emit a diagnostic note for code that might be affected. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=77728 GCC 5 and GCC 6 releases will continue to be affected by the ABI bug, since changing ABI in these releases is not practical. A warning enabled by -Wpsabi option was added to GCC 5 and GCC 6 toolchains to diagnose codebases that might be affected by the ABI bug. Additionally, this same bug was present in AArch64 backend in development versions of GCC 7. There was no releases of GCC with this bug present in AArch64 backend, therefore the release notes does not mention this. However, be advised that any code bases built with development versions of GCC 7 need to be recompiled with released version of GCC 7 to conform to ABI. For an explanation of GCC 7 series changes please see the following website: https://gcc.gnu.org/gcc-7/changes.html For help in porting to GCC 7 please see the following explanation: https://gcc.gnu.org/gcc-7/porting_to.html Download release-candidate packages from: (sources) http://snapshots.linaro.org/components/toolchain/gcc-linaro/7.2-2017.11-rc1/ (binaries) http://snapshots.linaro.org/components/toolchain/binaries/7.2-2017.11-rc1/ Previous snapshots and release-candidates are at: http://snapshots.linaro.org/components/toolchain/binaries/ Previous releases are at: http://releases.linaro.org/components/toolchain/binaries/ A description of the arm and AArch64 target triples can be found at: https://collaborate.linaro.org/display/TCWGPUB/ARM+and+AArch64+Target+Tripl… Host Requirements ================== Linaro officially supports the current and previous Ubuntu LTS releases (as of the time of this release).

Linaro bugzilla #3040 : CC1 and cc1plus cannot convert UTF-8. https://bugs.linaro.org/show_bug.cgi?id=3040 * The Linaro GCC 6.3-2017.05 snapshot added support for -mpure-code option to ARMv7-M and ARMv8-M targets. This option ensures functions are put into sections that contain only code and no data. * The GDB version was upgraded from GDB 8.0. * Previous versions of the Linaro GCC 6 toolchain, when -static -E/—dynamic-list are passed to the linker, might create executables with dynamic sections which aren’t supported by run-time. This was exhibited in Perf Tools build system and has been fixed upstream and backported into Linaro Binutils 2.27 branch. Linaro bugzilla #2926 : Perf tools compiled statically for AArch64 with Linaro release 6.1 and later ones was not statically linked. https://bugs.linaro.org/show_bug.cgi?id=2926 * The Linaro GCC 6.3-2017.03 snapshot fixed some ILP32 issues (TLS, exception handling, …) and these have been incorporated into this release. * Previous versions of the Linaro GCC 6 toolchain were incorrectly generating floating-point code for soft-float Linux targets (arm-linux-gnueabi, and armeb-linux-gnueabi). This escaped detection until recently because the soft-float targeted toolchains were configured to use general-purpose registers for passing floating-point values (which is what you would expect for soft-float toolchains) and the intra-routine floating-code was not noticed. The issue would only show up on targets that were run on hardware that truly didn't have floating-point hardware where the kernel did not trap and emulate floating-point routines. This has been solved in Linaro GCC 6.3-2017.02-rc2 by configuring the toolchain (using --with-float=soft) to generate code without any floating-point instructions at all (-mfloat-abi=soft). https://review.linaro.org/#/c/16968/2 This change should not break compatibility between existing binaries compiled with these toolchains since the float-point parameter passing ABI is still the same. * A bug/regression in the compiler has been identified whereby the target function that is invoked when calling a "weak" function directly is the "strong" override, whereas when calling the function via a pointer the "weak" implementation is used. This would be noticed as inconsistent function invocation when invoking directly vs. invoking via function pointer. This issue only affected 32-bit arm targets. This regression has been fixed upstream and backported into Linaro GCC 6.3-2017.02-rc2. GCC PR target/78253: [5/6/7 Regression] [ARM] call weak function instead of strong when called through pointer. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78253 Linaro bugzilla #2562: ARM GCC 5.2 call weak function instead of strong when called through pointer https://bugs.linaro.org/show_bug.cgi?id=2562 * MS Windows does not support symlinks and the MS Windows archive extractor does not properly deep copy the symlink target files/directories into the symlinked directory structure when unpacking the toolchain archive. This causes problems with missing dependencies when using the Linaro mingw toolchains, as identified in the following bugs: https://bugs.linaro.org/show_bug.cgi?id=2684 https://bugs.linaro.org/show_bug.cgi?id=2192 https://bugs.linaro.org/show_bug.cgi?id=2762 This has been solved by copying files rather than using symlinks when the mingw targetted toolchain archives are created. https://review.linaro.org/#/c/16415/ * Users of Linaro's toolchain have encountered problems when building projects with Autotools (specifically libtool): https://bugs.linaro.org/show_bug.cgi?id=2764 The Linaro binary toolchain release contained files with a .la suffix as artifacts of the toolchain build process. These .la files are helper files for libtool, but unlike a gcc install tree, they are not position independent and contain full paths. Since these artifacts contain absolute paths they can actually mislead user invocation of libtool into not finding required libraries (because they reference the build tree, not the install location) and hence breaking Autotools builds. These *.la file artifacts have been removed from Linaro toolchain binaries because they are unnecessary for users. * The Linaro GCC 6.3-2017.01 snapshot added further enablement for ARMv8-M and these have been incorporated into this release. * Compiling and statically linking some SPEC2006int tests against tcmalloc have been failing due to a problem with glibc's memory allocator function overrides. This was fixed upstream: https://sourceware.org/bugzilla/show_bug.cgi?id=20432 Backported into Linaro glibc 2.23: commit 058b5a41d56b9a8860dede14d97dd443792d064b Author: Florian Weimer <fweimer(a)redhat.com> Date: Fri Aug 26 22:40:27 2016 +0200 malloc: Simplify static malloc interposition [BZ #20432] * Host binaries for x86_64 linux hosts now have symbols and debug information stripped in order to reduce the size of the toolchain binary archives. This reduces the archive size from 1.5G to 600M for aarch64-linux-gnu target with the gcc-6-branch. * The GDB version was upgraded from GDB 7.11 in the Linaro GCC 6.1-2016.08 release to GDB 7.12 in the Linaro GCC 6.2-2016.11 release. * The Linaro GCC 6.2-2016.10 snapshot added AArch32 support for ARMv8.2 and ARMv8m, as well as some AArch64 fixes for ARMv8.2, and bug fixes merged from FSF GCC 6.2.
