[LLVM] - Submitted fix for PR36542, tracked down problem to LLVM not considering the target triple of the MachineFunction when relaxing branch instructions. [TCWG-1375]. - A lot of investigation of a difference in inline assembly between GCC and LLVM, reviewed and approved upstream patch D44815. - Review of upstream changes to support Short Thunks in LLD, managed to find a problem in algorithm and provided a solution. Looks like this could be approved soon. - Review of BFD and Gold patches for my PR on missing support for R_AARCH64_TLSLE_LDST family of relocations. I now need to implement these in LLD. [TCWG] Some post connect note taking and writing up. [Plans] - Continue work on PR36542, address any review comments. - Implement support for R_AARCH64_TLSLE_LDST family in lld. - Get back to building Android with LLD. Friday 30th and Monday the 1st are public holidays in UK.

[ANNOUNCE] Linaro Binary Toolchain Release-Candidate GCC 7.3-2018.04-rc1

by Mark Murray

[ANNOUNCE] Linaro Binary Toolchain Release-Candidate GCC 7.3-2018.04-rc1 The Linaro Binary Toolchain ============================ The Linaro GCC 7.3-2018.04-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/7.3-2018.04-rc1/ (binaries) http://snapshots.linaro.org/components/toolchain/binaries/7.3-2018.04-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).

[ANNOUNCE] Linaro Binary Toolchain Release-Candidate GCC 6.4-2018.04-rc1

by Mark Murray

The Linaro Binary Toolchain ============================ The Linaro GCC 6.4-2018.04-rc1 Release-Candidate is now available. The GCC 6 Release series has significant changes from the GCC 5 release series.

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. 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 6.4-2018.01 and Linaro GCC 6.4-2018.03 .

Progress: * VIRT-65 [QEMU upstream maintainership] + raspi3: came up with plausible fix for sd controller model that makes Linux driver work. Unfortunately it's pure guesswork since there's no public documentation for the hardware :-( + drafted a blog post describing booting Linux on the raspi3 model (for publication once we've got the sdcard fix in master) + tagged 2.12.0 rc0 (first release candidate), various other release work * VIRT-164 [improve Cortex-M emulation] + a little more progress with the stack-limit checking feature thanks -- PMM

[ACTIVITY] report week ending 16 Mar

by Peter Maydell

Progress: * VIRT-65 [QEMU upstream maintainership] + raspi3 board: tested with a Debian kernel, and fixed and sent patches for various issues that were causing it to panic. Unfortunately there's a more tricky issue with the sd controller still that means it doesn't boot yet... + bug investigation week: - LP:1748434: wrong logic for ICC_PMR and ICC_RPR accesses by NS code when the GICv3 emulation has security extensions enabled. Sent patch. - LP:1751674: segfault doing a VM memory dump on vexpress-a9. This is a combination of user error and a longstanding bug where the GICv2 crashes if you try to read its banked-per-CPU registers from a context that isn't a guest CPU (like the monitor or the gdbstub) - LP:1755479: confirmed that crash when using -icount is one that has been fixed by a patch from Pavel that was lurking in a record/replay series + handling all the merge requests for softfreeze * VIRT-164 [improve Cortex-M emulation] + started to look at implementing the stack-limit checking feature thanks -- PMM
