[ANNOUNCE] Linaro Binary Toolchain Release GCC 7.4-2019.02

by Mark Murray

The Linaro Binary Toolchain ============================ The Linaro GCC 7.4-2019.02 Release 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 packages from: (sources) http://releases.linaro.org/components/toolchain/gcc-linaro/7.4-2019.02/ (binaries) http://releases.linaro.org/components/toolchain/binaries/7.4-2019.02/ 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). This does not mean that the toolchain will not work on other/older Linux distributions. See the following for the life-time of Ubuntu LTS releases. https://wiki.ubuntu.com/Releases The host system upon which the cross-compiler will run requires a minimum of glibc 2.14, because of API changes to glibc's memcpy API. https://bugs.linaro.org/show_bug.cgi?id=1869 Package Versions ================= Linaro GCC 7.4-2019.02 http://releases.linaro.org/components/toolchain/gcc-linaro/7.4-2019.02/ FSF glibc 2.25 (release/2.25) https://lists.gnu.org/archive/html/info-gnu/2017-02/msg00002.html Newlib 2.5 (newlib-2_5_0 tag) https://sourceware.org/ml/newlib/2016/msg01191.html GNU Binutils 2.28 (users/linaro/binutils-2_28-branch) https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=blob_plain;f=bin… FSF GDB 8.2 (gdb-8.2-branch) https://lists.gnu.org/archive/html/info-gnu/2018-09/msg00001.html Linaro toolchain package git branches are hosted at: http://git.linaro.org/toolchain NEWS for GCC 7 (as of Linaro GCC 7.4-2019.02) ============================================== * Runtest and gdbserver are no longer installed in the toolchain bin/ directory. Binary releases no longer include runtest at all, and gdbserver is a target tool; it is now shipped in the sysroot under usr/bin/. LDTS case #2211: gdbserver and runtest in GCC binary release are in the wrong place or have the wrong name * Gdbserver is no longer linked statically, because this is currently unsupported. Linaro bugzilla #3344: gdbserver broken in Linaro 2017.02 https://bugs.linaro.org/show_bug.cgi?id=3344 * The Linaro GCC 7.4-2019.01 snapshot added a fix for Linaro bug 4007: "Internal compiler error with -mcpu=thunderx2t99". * The Linaro GCC 7.2-2017.09 snapshot added float and integer moves improvement for AArch64 targets. * The Linaro GCC 7.1-2017.07 snapshot added prefetching configuration improvement for AArch64 targets and laid groundwork to enabling prefetching in more cases. * Previous MinGW hosted version of Linaro GCC C preprocessor failed to convert character set used for string, character constants, etc. This is fixed in this release. Linaro bugzilla #3040 : CC1 and cc1plus cannot convert UTF-8. https://bugs.linaro.org/show_bug.cgi?id=3040 * Performance related backports from the following snapshots have been included: Linaro GCC 7.1-2017.05, Linaro GCC 7.1-2017.06, Linaro GCC 7.1-2017.07, Linaro GCC 7.2-2017.08, Linaro GCC 7.2-2017.09, Linaro GCC 7.2-2017.10, Linaro GCC 7.2-2018.04 and Linaro GCC 7.4-2019.01.

[LLVM-521] LLD and taking the address of an ifunc Went through the possible combinations (pic, pie, non-pic, exec, shared,...) found one relocation that gcc uses that clang doesn't, hence mc and LLD don't support. Raised upstream pr. Also found that clang's code-sequence for -fpie doesn't seem to guarantee ifunc pointer equivalence when linking -fpie (non-got generating sequence used when ifunc is in same translation unit). Will need some further investigation to confirm. [LLVM-499] Support for linking the linux kernel Committed -pic-veneer support and associated overflow fix, now merged to 8.0 branch. Other: - Started work on Fosdem presentation on LLD performance. Studying ld.bfd and ld.gold source code to look for structural differences between them and LLD. - Submitted presentation for next Linaro Connect - Review for comdat group and unused section elimination. - On buildbot duty.

Progress: * VIRT-65 [QEMU upstream maintainership] + some code review, and another arm pull-request (including RTH's pointer auth work) + sent patch fixing a bug in the gdbstub memory access path that meant it was always making accesses as NonSecure even if the guest CPU was currently Secure + sent patch fixing checkpatch to not wrongly complain about block comments starting "/**" * VIRT-268 [QEMU support for dual-core Cortex-M Musca board] + I have a model of the SSE-200 subsystem used by the Musca board, and a model of the MPS2 AN521 FPGA image which uses it. (Since it is basically "our existing MPS2 AN505 model, but with SSE-200 rather than IoTKit" it's a useful stepping stone to the Musca board.) There are still some bugs and missing features, but it seems to mostly be functional (it can run the ARM Trusted Firmware M test binary.) thanks -- PMM

[ANNOUNCE] Linaro GCC 7.4 2019.01 source snapshot

by Mark Murray

The Linaro Toolchain Working Group (TCWG) is pleased to announce the 2019.01 snapshot of the Linaro GCC 7 source package. The GCC 7 series introduced an ABI change for ARM targets by fixing a bug (present since GCC 5, see link below) that affects conformance to the procedure call standard (AAPCS). 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. If the option -Wpsabi is enabled (on by default) the compiler will emit a diagnostic note for code that might be affected by this ABI change. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=77728 For an explanation of the changes please see the following website: https://gcc.gnu.org/gcc-7/changes.html This snapshot1 is based on FSF GCC 7.4+svn267072 and includes performance improvements and bug fixes backported from mainline GCC. The contents of this snapshot will be part of the 2019.01 stable2 periodic release. Interesting changes in this GCC source package snapshot include: Updates to GCC 7.4+svn267072 Linaro bug 4007: “Internal compiler error with -mcpu=thunderx2t99” is fixed Feedback and Support Subscribe to the important Linaro mailing lists and join our IRC channels to stay on top of Linaro development. o Subscribe to the important Linaro mailing lists and join our IRC channels to stay on top of Linaro development. ** Linaro Toolchain Development mailing list: http://lists.linaro.org/mailman/listinfo/linaro-toolchain ** Linaro Toolchain IRC channel on irc.freenode.net at #linaro-tcwg * Bug reports should be filed in Bugzilla against GCC product: http://bugs.linaro.org/enter_bug.cgi?product=GCC * Interested in commercial support? inquire at Linaro support: mailto:support@linaro.org [1].

cannot build "Hello World" project

by Jie Sheng

Hi, I am new to the Linaro toolchain and has followed the tutorial https://www.youtube.com/watch?v=xNHIAHJ2ceY from Part 1 to Part 3. I downloaded gcc-linaro-7.3.1-2018.05-i686-mingw32_aarch64-elf.tar.xz<https://releases.linaro.org/components/toolchain/binaries/latest-7/aarch64-…> and unzipped it. The toolchain is GCC7.3.1. [aarch64-elf]. I tried to build the "Hello World" project, and typed "--specs=aem-ve.specs" in all configurations just as the video did. Then I got errors shown in the attached picture. Would you please help? BTW my machine is x86 64 bit. Did I install the correct version of toolchain? Looking forward to your reply! regards, Jenny [https://www.bing.com/th?id=OVP.6Rb47fIamx6ZsOb2OWQm3AEsDh&pid=Api] <https://www.youtube.com/watch?v=xNHIAHJ2ceY> Part 3 - Create a Project for ARMv8 Model<https://www.youtube.com/watch?v=xNHIAHJ2ceY> www.youtube.com This video series explains how to run applications on ARMv8 model using the ARM DS-5 Development Studio.

[LLVM-520] LLD Fix movt/movw relocation overflow Now committed upstream. [LLVM-521] Taking the address of an ifunc in AArch64 Prompted by a bug report and comment about pointer equivalence, spent some time looking into gold, lld and bfd behaviour to ensure that LLD is at least correct. Other Some investigation into LLD non-support of common-page-size and whether this is significant for code-size. Used in response to query about whether LLD should change default value of max-page-size. Thoughts about whether a linker must generate cantunwind .ARM.exidx sections for code sections missing a .ARM.exidx section. If C++ code with exceptions is interleaved with some assembly code without .ARM.exidx sections then the assembly code can match the address range of the C++ code that precedes it.

[ANNOUNCE] Linaro Binary Toolchain Release GCC 6.5-2018.12

by Mark Murray

The Linaro Binary Toolchain ============================ The Linaro GCC 6.5-2018.12 Release is now available. The GCC 6 Release series has significant changes from the GCC 5 release series. For an explanation of the changes please see the following website: https://gcc.gnu.org/gcc-6/changes.html For help in porting to GCC 6 please see the following explanation: https://gcc.gnu.org/gcc-6/porting_to.html Download release packages from: (sources) http://releases.linaro.org/components/toolchain/gcc-linaro/6.5-2018.12/ (binaries) http://releases.linaro.org/components/toolchain/binaries/6.5-2018.12/ 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). This does not mean that the toolchain will not work on other/older Linux distributions. See the following for the life-time of Ubuntu LTS releases. https://wiki.ubuntu.com/Releases The host system upon which the cross-compiler will run requires a minimum of glibc 2.14, because of API changes to glibc's memcpy API. https://bugs.linaro.org/show_bug.cgi?id=1869 Package Versions ================= Linaro GCC 6.5-2018.12 http://releases.linaro.org/components/toolchain/gcc-linaro/6.5-2018.12/ Linaro glibc 2.23 (linaro/2.23/master) https://lists.gnu.org/archive/html/info-gnu/2016-02/msg00009.html Linaro newlib 2.4-2016.03 (linaro_2.4-branch) https://sourceware.org/ml/newlib/2016/msg00370.html Linaro binutils 2.27 (users/linaro/binutils-2_27-branch) https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=blob_plain;f=bin… Linaro GDB 8.2 (gdb-8.2-branch) https://lists.gnu.org/archive/html/info-gnu/2018-09/msg00001.html Linaro toolchain package git branches are hosted at: http://git.linaro.org/toolchain NEWS for GCC 6 (as of Linaro GCC 6.5-2018.12) ============================================== * Runtest and gdbserver are no longer installed in the toolchain bin/ directory. Binary releases no longer include runtest at all, and gdbserver is a target tool; it is now shipped in the sysroot under usr/bin/. LDTS case #2211: gdbserver and runtest in GCC binary release are in the wrong place or have the wrong name * Gdbserver is no longer linked statically, because this is currently unsupported. Linaro bugzilla #3344: gdbserver broken in Linaro 2017.02 https://bugs.linaro.org/show_bug.cgi?id=3344 * Previous MinGW hosted version of Linaro GCC C preprocessor failed to convert character set used for string, character constants, etc. This is fixed in 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 8.1 to 8.2. * 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. This is available in the binary toolchain as of Linaro GCC 6.2-2016.11. * Basic tuning support for the Qualcomm qdf24xx was added to the Linaro GCC 6.2-2016.10 snapshot and is available in the binary toolchain as of Linaro GCC 6.2-2016.11. * IFUNC was disabled for baremetal targets, as it was causing test-suite failures, and is presently a Linux only feature. * The gold linker was added to this binary release. * Backported malloc_lock fix into Linaro newlib 2.4. commit 2665915cfc46aa6403bb2efd473c523d3167e0cb Author: Andre Vieira (lists) <Andre.SimoesDiasVieira(a)arm.com> Date: Thu Jun 16 12:23:51 2016 +0100 Re-enable malloc_lock for newlib-nano * Backported rawmemchr patch into Linaro newlib 2.4. commit e7b1ee2ea6aa3ee1da41976407410e6202a098c5 Author: Wilco Dijkstra <Wilco.Dijkstra(a)arm.com> Date: Thu May 12 16:16:58 2016 +0000 Add rawmemchr * Backported strlen fix when using Thumb-2 and -Os -marm into Linaro newlib 2.4. commit 5c02bcc086a96b174e1b9e1445a4a1770070107a Author: Thomas Preud'homme <thomas.preudhomme(a)arm.com> Date: Wed May 11 17:18:48 2016 -0400 Fix strlen using Thumb-2 with -Os -marm * Backported fix for semihosting ARM when heapinfo not provided by debugger into Linaro newlib 2.4. commit 5c9403eaf40951f8a4f55ed65f661b485ff44be7 Author: David Hoover <spm2(a)dangerous.li> Date: Thu Apr 21 07:12:24 2016 +0200 Fixed semihosting for ARM when heapinfo not provided by debugger. * Merged latest FSF glibc release/2.23/master into Linaro glibc 2.23. * Backported __ASSUME_REQUEUE_PI check Linaro glibc 2.23 branch. commit 2d20c3bf918cd94ebd4106693adb3a5c9272baba Author: Adhemerval Zanella <adhemerval.zanella(a)linaro.org> Date: Tue May 17 10:16:39 2016 -0300 Add runtime check for __ASSUME_REQUEUE_PI (BZ# 18463) * Backported removal of __ASSUME_SET_ROBUST_LIST from Linaro glibc 2.23 branch. commit bb8f09d72756186a3d82a1f7b2adcf8bc1fbaed1 Author: Adhemerval Zanella <adhemerval.zanella(a)linaro.org> Date: Mon May 16 19:01:10 2016 -0300 Remove __ASSUME_SET_ROBUST_LIST * Backported removal of __ASSUME_FUTEX_LOCK_PI from Linaro glibc 2.23 branch. commit e48b4e7fed0de06dd7832ead48bea8ebc813a204 Author: Adhemerval Zanella <adhemerval.zanella(a)linaro.org> Date: Mon May 16 10:35:25 2016 -0300 Remove __ASSUME_FUTEX_LOCK_PI * Merged latest FSF binutils-2_27-branch into linaro_binutils-2_27-branch. * The libwinpthread DLL is now copied into the host bin directory to satisfy mingw package dependencies. * Backported GNU Linker fix. commit fbc6c6763e70cb2376e2de990c7fc54c0ee44a59 Author: Nick Clifton <nickc(a)redhat.com> Date: Tue Aug 23 09:45:11 2016 +0100 Fix seg-fault in ARM linker when trying to parse a binary file. * Backported GNU Assembler fix for PR 20364 commit 5fe7ebe5ab43750abf8f490b785d99a1e598e7fd Author: Nick Clifton <nickc(a)redhat.com> Date: Fri Aug 5 10:37:57 2016 +0100 Fix the generation of alignment frags in code sections for AArch64. https://sourceware.org/bugzilla/show_bug.cgi?id=20364 * Performance related backports from the following snapshots have been included: Linaro GCC 6.1-2016.06, Linaro GCC 6.1-2016.07, Linaro GCC 6.1-2016.08, Linaro GCC 6.2-2016.09, Linaro GCC 6.2-2016.10, Linaro GCC 6.2-2016.11, Linaro GCC 6.2-2016.12, Linaro GCC 6.3-2017.01, Linaro GCC 6.3-2017.02, Linaro GCC 6.3-2017.03, Linaro GCC 6.3-2017.04, Linaro GCC 6.3-2017.05, Linaro GCC 6.3-2017.06, Linaro GCC 6.4-2017.07, Linaro GCC 6.4-2017.08, Linaro GCC 6.4-2017.09, Linaro GCC 6.4-2017.10, Linaro GCC 6.4-2018.04 and Linaro GCC 6.5-2018.11.
