[ANNOUNCE] Linaro Binary Toolchain Release-Candidate GCC 5.4-2017.01-rc2

by Ryan Arnold

The Linaro Binary Toolchain ============================ The Linaro GCC 5.4-2017.01-rc2 Release-Candidate is now available. Notice: All Linaro GCC 5 series toolchain users should migrate to the latest version of the Linaro GCC 5 toolchain in order to mitigate potential security exposure to CVE-2015-7547. See the NEWS section below for details. Download release-candidate packages from: http://snapshots.linaro.org/components/toolchain/gcc-linaro/5.4-2017.01-rc2/ http://snapshots.linaro.org/components/toolchain/binaries/5.4-2017.01-rc2/ 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/ 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 5.4-2017.01-rc2 Linaro glibc 2.21 (linaro/2.21) Linaro newlib 2.1.0-2014.09 (linaro_newlib-branch) Linaro binutils 2.25 (linaro_binutils-2_25-branch) FSF GDB 7.12 (gdb-7.12-branch) Linaro toolchain package git branches are hosted at: http://git.linaro.org/?a=project_list&s=toolchain%2F&btnS=Search NEWS for Linaro GCC 5.4-2017.01-rc2 ==================================== * Include GCC fix for upstream bugzilla 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 * Include GCC fix for Linaro bugzilla #1925: [regression] FAIL: libgomp.fortran/retval1.f90 -O1 execution test https://bugs.linaro.org/show_bug.cgi?id=1925 * Include GCC fix for Linaro bugzilla #2185: aarch64-linux-gnu-g++ internal compiler error: in curr_insn_transform https://bugs.linaro.org/show_bug.cgi?id=2185 * Copy the libwinpthread DLL into the bin directories so it gets into the tmp directory before tar is run. https://review.linaro.org/#/c/13723/ * Increment binutils release date to 2016_02 to reflect the most recent commit: commit ef90a4718f535cbe6345b4e7168baea7b1972abf Author: Matthew Wahab <matthew.wahab(a)arm.com> Date: Tue Jan 12 16:35:30 2016 +0000 [ARM] Support ARMv8.2 RAS extension. * Baremetal sysroot names now contain 'newlib' rather than 'glibc'. * Manifests now contain relative paths rather than absolute paths. * Now generating proper manifest files. * Fixed pi requeue support in glibc 2.21 while allowing the existing 2.21 minimum kernel default setting.

=== This Week === Monitor LLDB buildbot for minimum down time. [TCWG-712] [1/10] -- LLDB Arm build was broken and then fixed upstream but a buildbot script bug. -- Fixed buildbot script to make sure not every type of build is refreshed after a breakage. Investigate LLDB testsuite failures on Pine64 target (AArch32 and AArch64 modes) [TCWG-1012] [3/10] -- Investigated and fixed TestRegisterVariables (https://reviews.llvm.org/D28666) -- Fixed a log issue which I initially thought was a bug. (https://reviews.llvm.org/rL291889) -- No further AArch64 failures except for one test timedout needs further investigation. -- Some tests fail randomly on AArch32 but pass when run individually. More investigation needed. LLDB Arm/AArch64 Investigate and fix testsuite crashes (Pine64 Crashes) [TCWG-792] [2/10] -- There was some problem occuring when multiple versions of python are installed on tester. -- Also some tests are leaving behind runaway processes. -- Cleaned up testers removed python issue ended up reducing test time to 3 minutes. -- Trying to track runaway processes. Miscellaneous Activities [4/10] -- Travel to Islamabad for Hungary visa interview (9th-10th Jan 2017). -- Meetings, Emails etc. === Next Week === ARM/AArch64 hardware breakpoints [TCWG-717] -- Investigate current status and create task breakdown. Investigate LLDB testsuite failures on Pine64 target (AArch32 and AArch64 modes) [TCWG-1012] -- Further tracking on runaway processes when running AArch32 testsuite. -- Investigation of timedout tests on AArch64.

[TCWG-614] Long branch thunks: Implemented a prototype of the existing Thunk implementation using Synthetic (Linker created sections) and moved it close to the area it will need to go for Long Branch Thunk work. Worked on this exclusively all week. Plans for next week: [TCWG-614] Long branch thunks: Tidy up and refactor prototype to a point where I can post for upstream review. This won't be long-branch thunk support but it will be a significant intermediate step. Do a draft plan of Connect submission and decide how long I need.

== Progress == * [ARM] Use AddDefaultPred everywhere [TCWG-987] [1/10] - Proposed a refactoring first [TCWG-1015] - Rebased initial patch after the refactoring, still waiting for review * Refactor AddDefaultPred [TCWG-1015] [4/10] - Initial implementation was a bit heavyweight, so I worked on a simpler version based on people's suggestions - Committed upstream * Misc [5/10] - Got up to speed after vacation - Booked travel for Connect and EuroLLVM - FOSDEM slides - Upstream code reviews - Reverted and ran pre-commit tests for some compiler-rt patches that broke the buildbots == Plan == * 3 days off (Mon-Wed) * [ARM GlobalISel] Add support for integers < 32 bits wide [TCWG-980] - I have 3 patches in upstream review, I will keep pinging them - Putting GlobalISel work on hold until these patches go through

~ Progress ~ * TCWG-984 Handle exception/error in disassembly, [4/10] Patches are posted and reviewed. Three patches to opcodes are approved and committed. V2 is done to address comments on C++ and unit tests. V2 are being tested. * Patches review, [4/10] ** Review some preparatory SVE patches from Alan. They are good to me, but I expect Joel or someone else to take a look as well. ** Linux kernel awareness debugging. Review the patch sent from linaro, but some one from IBM sends a similar patch series. These two patch sets look similar, but are different on some parts. * Conversation with Paul (openocd maintainer) on irc. [1/10] They really want me to look at some gdb+openocd issues. My Hikey will arrive soon, but they give me some explanations on why cortex-m board is better than cortex-a board in bare-metal, because of simplicity. I explained to them why Linaro focused on cortex-a devices so far. * Linaro Connect. [1/10] Register the connect, book flight and hotel. ~ Plan ~ * TCWG-984 and TCWG-333 * Carefully read Dave M's SVE user space VL control API. * Carefully read IBM's kernel debugging patches. -- Yao Qi

Re: Does Linaro's GCC 4.9 include Crypto extensions and intrinsics?

by Jeffrey Walton

Thanks guys, that was it. I did not realize the build system was omitting the flags.

Does Linaro's GCC 4.9 include Crypto extensions and intrinsics?

Please forgive my ignorance. I'm working on a Pine64 dev-board Pine64 supplies Linaro's GCC 4.9.2 toolchain. I am catching a compile error, and I am trying to determine why.
