== Progress == - Looked into Cbuild2 and current benchmarking scripts - Talked to Rob to understand the requirements and plan for next 2 weeks - Backported gcc testcase fix that causes regression in Linaro 4.8 for armv5te. == Plan == - Taking leave next week. - Start with benchmarking scripts after that

Worked from AMD Austin. == Progress == * TLS based libssp support. Solved segmentation faults in clone and fork tests regressing from the patch I wrote. Ran glibc tests. Two tests still fail, tst-cancel-17.c and tst-memqueue8.c. They both use pthread_cancel and with my patch they time out. Debugging it to find the cause. Informed Maintainer about my status and got some advice to debug. == Plan == * Taking vacation next week. * But will continue send out gcc patch for libssp. * reinstall ubuntu on my laptop

== 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.
