== Issues ==
* None
== Progress ==
* Take care lp: 1270040, lp:1278337 and Beagleboard "Abort" issue.
* Respawn 2014.01 release to use newlib-linaro-2.1.0-2014.02 for
baremetal toolchains
(http://cbuild.validation.linaro.org/binaries/2014.01-01/)
* Test codes to duplicate shared compares to get more conditional
compares. Fix the bootstrap issue. But the latest test does not show
performance improvement in Spec2K.
* Rebase and test the CCMP patch.
* Read document about aarch64 CCMP/CCMN instructions and write
codes/patterns to generate the instructions. Test is ongoing.
== Plans ==
* Ccmp for AARCH64.
== Progress ==
* Figure how to have tcwgweb and cbuild-tools process the test
results from Jenkins and produce the diffs for comparison.
(TCWG-391 6/10)
* Wrote script to convert Jenkins produced data files to tcwgweb format.
(TCWG-391 1/10)
* Meetings and misc. (3/10)
- Worked on LCA14 presentation.
== Plan ==
* Continue fighting with tcwgweb to run test comparisons for Jenkins
builds. TCWG-391)
* Now that SSH is setup correctly in the TCWG build farm, GCC
testing tries to execute the remote tests, but hit's an error in
DejaGnu, which needs to be debugged and fixed. (TCWG-324)
== Leave ==
* Off to Nepal & Mt Everest after Connect.
== This week ==
Monday - Off
Reworked backports off origin instead of crypto-backport branch. Also used read/write git branch to push
- Affected backports 201164-206168, 201170, 201175, 201261, 201263 and 202020
Submitted backports for code review via git review
- Aarch64 ILP backports: 201164-206168, 201170, and 201175
- Aarch64 support for NEG in vectors registers: 201261 and 201263
- Aarch64 support for SISD shifts: 202020
== Next week ==
Submit backport 202256 for code review
Backport 202407 assigned to me
== Future ==
Things you plan to do in the future.

The Linaro Toolchain Working Group is pleased to announce the 2014.02
engineering release of Linaro GCC 4.8.
As announced at Linaro Connect USA 2013 Linaro GCC is moving to a
pattern of quarterly stable releases, with engineering releases in the
intervening months. This is the first engineering release. The next stable
release will be the 2014.04 release.
Linaro GCC 4.8 2014.02 is the eleventh release in the 4.8 series. Based
off the latest GCC 4.8.3+svn207411 release, it includes performance
improvements and bug fixes.
Interesting changes include:
* Updates to GCC 4.8.3+svn207411
* ARM-v8 crypto intrinsics support
* New vectorizer cost model
The source tarball is available from:
http://releases.linaro.org/14.02/components/toolchain/gcc-linaro/4.8
Downloads are available from the Linaro Releases website:

Hello,
I'm maintaining an older release we have which uses the older toolchian
binaries in gcc-linaro-arm-linux-gnueabi-2012.03-20120326_linux. I've
identified a bug in glibc we appear to be encountering and would like to
port the fix back.
I initially went the route of compiling the above toolchain binaries from
source as described in the readme.txt but then found that the cross
compiler binary build does not include the e/glibc build and these appear
to be sucked in in binary form (oneiric-sysroot-r1).
Are there any documents how these prebuilt libc binaries were created?
Please note that I'm not asking in general how to build glibc. I've built a
version with and without this bug patched to verify that it is indeed what
we are hitting. I'm more hoping to get an idea of how the specific binaries
mentioned above were built.
Thanks in advance for any help!
Evan Carson

Hello,
The binutils 2.24-2013.12 release page says that the release was built
from the linaro_binutils-2_24-2013_12_release tag, but that tag
doesn't seem to actually be present in the git repo at
http://git.linaro.org/toolchain/binutils.git . Could that tag please
be pushed?
Thanks and regards,
Gregory
