[ACTIVITY] Week 41

by Renato Golin

== Progress == * EEMBC - Updating Linaro image with Clang toolchain changes - Updating compare_all script to rank boards - Investigating differences in performance against GCC * ODroid XU - Setting up server image (Linaro 13.09 + odroid specific changes) - CPU scheduler is a mess, forcing "performance" governor at boot seems to work - No journal in root fs, remounts ro all the time (bad image?) - LLVM builds are slow (as fast as Chromebook), maybe it's the SDCard - Setting it as self-host buildbot in the lab, going well * Background - Massive patch review (Sub-Register Live Range Analysis for NEON/VFP et al) - LLVM Sync and EuroLLVM meetings == Plan == * Continue investigating performance problems in EEMBC * Check Odroid XU internal buildbot for stability

Error

by Rick

Hi Term, I have try to us "crosstool-ng-linaro-1.13.1-4.8 "to build myself cross tool chain, but some problem happened,just before I have used crosstool-ng offcial version, every thing is fine,I have got my toolchain, my operation system is Ubuntu 12.10, when I change to crosstool-ng-linaro, I am follow these steps. ct-ng list-samples, ct-ng linaro-arm-linux-gnueabihf ct-ng menuconfig I just change Local tarballs directory ,Prefix directory ,and change target os from prebuilt to linux, then,I build it,first time error happened at step "cc_core_pass_1 ",I google it and found out it is about multilib,I need to install gcc-multilib and g++-multilib, then,I continue,this time,error happened at step"cc_core_pass_2 ". related messages in build.log: [ALL ] Supported emulations: armelf_linux armelf armelfb armelfb_linux [ERROR] collect2: error: ld returned 1 exit status [ERROR] make[4]: *** [libgcc_s.so] Error 1 [ALL ] make[4]: Leaving directory `/work/software/cortexa9-linaro-build/.build/arm-linux-gnueabihf/build/build-cc-core-shared/arm-linux-gnueabihf/arm-linux-gnueabi/libgcc' [ERROR] make[3]: *** [multi-do] Error 1 [ALL ] make[3]: Leaving directory `/work/software/cortexa9-linaro-build/.build/arm-linux-gnueabihf/build/build-cc-core-shared/arm-linux-gnueabihf/libgcc' [ERROR] make[2]: *** [all-multi] Error 2 [ALL ] make[2]: Leaving directory `/work/software/cortexa9-linaro-build/.build/arm-linux-gnueabihf/build/build-cc-core-shared/arm-linux-gnueabihf/libgcc' [ERROR] make[1]: *** [all-target-libgcc] Error 2 [ALL ] make[1]: Leaving directory `/work/software/cortexa9-linaro-build/.build/arm-linux-gnueabihf/build/build-cc-core-shared' [ERROR] [ERROR] >> [ERROR] >> Error happened in: main[scripts/crosstool-NG.sh] so,I really don't know how to do now,any help is welcome.Thank you Cheers,Rick

Does Linaro aarch64 gcc toolchain support Cortex-A53/A57 performance tunning.

by Zenon Xiu

Hi team, In the GCC.pdf of gcc-linaro-aarch64-none-elf-4.8-2013.08, it says that -mcpu supports cortex-a53, but when I tried to build a simple hello bare metal application with -mcpu=cortex-a53 option, gcc reports, Error: unknown cpu `cortex-a53' Error: unrecognized option -mcpu=cortex-a53 Could you please confirm whether Cortex-A53/A57 performance tunning is supported? Thanks.

[ANNOUNCE] Aarch64 toolchain binaries respin 2013.09-01 released

by Bernhard Rosenkränzer

We have spotted a problem with the GOT layout in binaries generated by the 2013.09 Aarch64 toolchain, causing them to crash on startup. New builds fixing this issue are now available at http://releases.linaro.org/13.09/components/toolchain/binaries The arm-linux-gnueabihf and arm-none-eabi toolchains are not affected by this problem - there is no respin version for those builds. The Linux version is supported on Ubuntu 10.04.3 and 12.04, Debian 6.0.2, Fedora 16, openSUSE 12.1, Red Hat Enterprise Linux Workstation 5.7 and later, and should run on any Linux Standard Base 3.0 compatible distribution. Please see the README about running on x86_64 hosts. The Windows version is supported on Windows XP Pro SP3, Windows Vista Business SP2, and Windows 7 Pro SP1. The binaries and build scripts are available from: http://releases.linaro.org/13.09/components/toolchain/binaries Need help? Ask a question on https://ask.linaro.org/ Already on Launchpad?
