(https://groups.google.com/a/linaro.org/forum/#!forum/cbuildv2) * Got email notifications working for commits to cbuildv2 repository. * Continued work on release building via Cbuildv2. Source tarballs checked out OK, binaries too. Probably a few tweaks left to cover the minor differences, which are all documentation files. - Rebuild GCC dynamically so the shared libraries for libgcc and libstdc++ can go in the runtime binary tarball. - Build runtime binary tarball. - Added install script to sysroot tarball. - Make overriding the default release tag with a user supplied one work fully. * Got Odroid U2 board working again, did complete native build using cbuildv2. * Reviewed more cbuild2 patches from Ryan. * Got Jenkins building snapshot tarballs. == Plan == * Do slides for Connect presentation. * Work on duplicating the 2013.10 release via cbuildv2. * Get Odroid X2 board to boot, which it currently refuses to do. * Try to work around problem with importing test results. * Copy tarballs to snapshots.linaro.org.

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? Submit a bug at https://bugs.launchpad.net/linaro-toolchain-binaries On IRC? See us on #linaro on Freenode. Other ways that you can contact us or get involved are listed at https://wiki.linaro.org/GettingInvolved.

== 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

process for enabling gccgo in Linaro GCC binary distributions

Hi, With the patch I just sent to this list in place, gccgo builds for aarch64. I don't know how well it _works_ -- "hello world" builds and runs -- but I would like to ask what the process would be to get gccgo included in the binary distributions of GCC that Linaro makes. Cheers, mwh

MPFR build issue

by Kugan

Hi, With respect to the MPFR build error, (http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58578), is movs appropraite as shown below? When _err1 is negative the condition is evaluating it to be true. /* C Codeoes */ if (_err1 > 0) { /* working code */ .loc 1 67 0 cmp r3, #0 ble .L6 /* not working code*/ .loc 1 67 0 movs r3, r3, asl #1 ble .L6 When I looked at the ARM documents, I found the following Condition flags ------------------- If S is specified, for MOV instructions: 1. update the N and Z flags according to the result 2. can update the C flag during the calculation of Operand2 (see Flexible second operand) 3. do not affect the V flag. And also le Signed less than or equal. (Z==1) || (N!=V) Does this means we cant movs at comparision. http://gcc.gnu.org/ml/gcc-patches/2013-02/msg00861.html added this and I guess it is intentional. Am I missing anything here? Thanks, Kugan
