== Progress == * Enabled building GDB in all Cbuildv2 builds for --build all. * Added support for Cbuildv2 to to build GDB source tarball. * Got Canadian Crosses building via Cbuildv2, although I have to apply a one line patch, which I was trying to avoid. * Enabled Canadian Cross builds via Jenkins. * Source and binary snapshots builds via Jenkins now getting copied to snapshots.linaro.org. * Got started migrating Christophe's neon intrinsic test cases to GCC testsuite. * Added DejaGnu 'linaro' branch to Cbuildv2 infrastructure so the new baseboard files are available for Jenkins builds. * Applied Christophe's libsanitizer patch on aarch64 APM board and tried to get GCC to compile. Unsuccessful so far. * Installed crouton 'saucy' on new HP Chromebook 11. * Installed Fedora 19 on Samsung Chromebook. * Started adding support to Cbuildv2 for building LLVM and Clang and other components. I wish they all used autotools. :-) * Got Gerrit working for GCC and Cbuildv2. The LAVA team has been very helpful, but the setup docs miss way too many critical details. == Plan == * Figure out how to gpg sign the tarballs cbuildv2 is producing in a secure manner. * Finish adding support for building GDB binary tarballs. * More work on neon intrinsics test cases. * Work with new team member Mike to help him get up to speed on all things Linaro. * Try to get GCC trunk to build on aarch64. * Off to the "Hacker's Conference" out here in Santa Cruz, back home late Monday night. == Issues == * Eglibc defines caddr_t as a typedef, where auto-host for a Canadian Cross defines caddr_t, so stage2 fails to build. * Sucked up all the disk space in the toolchain_cloud instance, so all Jenkins builds are not working. * We'd like to rename Cbuildv2 to something else, suggestions welcome. :-)

== Progress == * LLVM Dev. Meeting 2013 * Meetings with Google, Qualcomm and ARM about Android and LLVM * We're creating a task force to move Android to be compiled with Clang by default, kernel, libraries, userland, native apps, Renderscript. * Agreed on some actions for public benchmarking - Hal will move tests to benchmarks by hand - Linaro will create bots on that sub-set == Plan == * Recuperate * Work on the stride vectorizer * Create benchmark bots * Start a TableGen doc seed, so experts can chime in * Prepare something for the CUCL LLVM Day on the 18th

== 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.
