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?

by Christophe Lyon

== Progress == * AArch64 frame grows downward: no feedback yet. * Disable-peeling: Vectorizer cost model has been changed upstream, the current default now includes the effect of disabling peeling. I have submitted benchmark jobs to check the exact effet; expecting some regressions since the reduced test case I was working on now generates the same code as with my patch. * AArch64 bootstrap failure: build it still on-going, so still hoping to reproduce it. * GCC trunk validation: - good progress on reporting - cross-validating several configurations (currently 18) for each upstream commit is too much for our compute farm to handle. Reduced to patches related to ARM/AArch64, but then we can miss regressions caused by other generic patches. * Backports: - committed a few simple ones. == Next == * AArch64 frame grows downward: continue * Disable-peeling/new vectorizer cost model: analyze bench results * Backports : check which ones can be reasonably done

by Rob Savoye

== Progress == * Fixed my laptop's desktop by upgrading to saucy & Gnome 3.10. * Continuing with Jenkins/Cbuildv2/Git integration. Since this is an ongoing task, I think I'm going to stop listing it every week. :-) * Fixed more bugs in Cbuildv2 when handling branches and revisions. * Compared source tarballs for binutils and gcc, Linaro releases against Cbuildv2 produced ones. * Added support to Cbuildv2 for building binutils source releases in the same style as src-release. * Worked on aarch64 builds on real hardware to test adding libatomic and go to builds. * Added support to build all documentation, which is used when building tarballs. * Reviewed and applied Cbuildv2 patches from Ryan. == Plan == * Try to work around problem with importing test results. * Continued work on release building via Cbuildv2. * Get Odroid boards working reliably, ordered AC powered USB hubs to work around problem with exterrnal USB drives.
