The Linaro Toolchain and Builds and Baselines Working Groups are pleased to
announce the 2013.10 release of the Linaro Toolchain Binaries, a pre-built
version of Linaro GCC and Linaro GDB that runs on generic Linux or Windows
and targets the glibc Linaro Evaluation Build.
Uses include:
* Cross compiling ARM applications from your laptop
* Remote debugging
* Build the Linux kernel for your board
What's included:
* Linaro GCC 4.8 2013.10
* Linaro GDB 7.6.1 2013.10
* A statically linked gdbserver
* A system root
* Manuals under share/doc/
The system root contains the basic header files and libraries to link your
programs against.
Interesting changes include:
* The sample configurations no longer require the LSB tools
* The build now works behind a HTTP proxy
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:
https://releases.linaro.org/13.10/components/toolchain/binaries/

== Issues ==
* None
== Progress ==
* Commit the fix for lp:1243022 on trunk.
* Backporting r203603, r204247 and r203267 to Linaro gcc 4.8.
* Updating CCMP patch according to comments.
* Collect spec2K result for CCMP.
- Overall there is no regression and no improvement.
- 175.vpr is sensitive to branch cost. Smaller branch cost will lead
to regression for it even with CCMP.
* Investigate bare metal arm-none-eabi A profile multilib build.
- Need fix the conflict with current multilib support for arm-linux-gnueabihf
- Need scripts and config update to meet the check of
--with-multilib-list=aprofile
- A reference build is shared at
http://cbuild.validation.linaro.org/snapshots/aprofile-baremetal.tar.bz2
== Plan ==
* Continue on CCMP.
* Update Linaro crosstool-ng for bare metal A profile multilib build.
== Progress ==
(TCWG-266), (TCWG-270), (TCWG-250), (TCWG-280) and (TCWG-288)
* Arm process record:
- Created Patches for all fixes and features.
- Performed testing in arm native and remote configuration.
- Performed regression testing on arm and x86.
- Submitted all fixes in three patch series.
* Performed GDB testsuite run on arm and x86 to get current status with new
patches.
There seems to be more test passing on arm than x86 with recent patches.
* Prepare for connect and travel to Santa Clara.
== Plan ==
* Linaro Connect US 2013
== Progress ==
* Got Odroid XU board stable by using Arch Linux. None of the
Ubuntu derived images worked more than barely. Tried a suggested
hack to use cpufreq-set -g performance, which allowed a fresh
install of saucy to work. Did new builds and test run.
* Got remote toolchain testing working on the newly functioning
Odroid board(s) and chromebook. Currently baseboard support is in
a DejaGnu branch,
http://git.savannah.gnu.org/cgit/dejagnu.git/?h=linaro. I'm
adding the global site.exp file to Cbuildv2, so 'make check'
executes tests via ssh on remote targets.
* Uploaded test results of ARM native builds to
cbuild.validation.linaro.org for tcwg-web. (look for version
gcc-linaro-4.8-2013.10.24)
* Added support to DejaGnu to use a custom port for ssh and scp.
* Survived learning to use Concur for expense reports.
== Plan ==
* Attend Connect, do presentation, go to others.
* Try to work around problem with importing test results. (need to
work with LAVA team for this one, will do at Connect)
* Copy tarballs to snapshots.linaro.org. (need to work with LAVA
team for this one, will do at Connect)
== Issues ==
* I see to be having random stability issues with the two Odroid
boards, although did manage to complete a test run of a the
execute tests.
== Progress ==
* Ongoing refactoring of malloc to improve performance
* Preparation for Connect
== Issues ==
* None
== Plan ==
* Linaro Connect US

== Progress ==
* Getting ready for Connect & LLVM US
* Stride Vectorization
- Added some logic to detect read/write reduction, possibly not the best
solution
- Consolidating all discussion into a single document for easy referral
- Creating several bugs (PR17673,PR17677,PR17678,PR17679,PR17680,PR17681)
* Re-Vectorizing
- A bug was passing the vectorizer again on an already vectorized loop
(PR17662)
- http://llvm-reviews.chandlerc.com/D2011, commit r193349
* Odroid XU
- Running more stable now, self-hosting doing well (more than a week on
24/7)
* Background
- Lots of patch reviews
- Lots of discussions about stride vectorization and others
== Plan ==
* Connect US next week
* US LLVM Dev Meeting the following
* Will be back in 2 weeks
== Issue ==
* Can not attend LCU'13 due to slow US Visa process.
== Progress ==
* Investigate lp:1243022:
- Root cause: REG_INC note is lost in subreg2 pass, so ira gets
wrong result in function validate_equiv_mem.
- Work out a patch for community review.
* Send conditional compare (CCMP) patch for community review.
- Benchmark testing is ongoing.
* Investigate heuristics to control ifcombine. Basically it will take
branch taken probability, frequency, branch-cost and basic block
reorder into account.
== Plan ==
* Performance tuning for CCMP.
