== Last week == * Sent a fix for PR target/46329 upstream. * Discussed with Richard Guenther how to represent the interleaved load/store "functions" that we're adding to gimple. Sent a patch upstream for comments. Richard confirmed on IRC that he was happy with it, and no-one else has objected. * Spent most of the week on the vectorisation itself, and on the testsuite. == This week == * Finish work on vectorisation testsuite and submit.

[ACTIVITY] 4th - 9th April

The test results for the patch for lp:675347 on GCC 4.6 came back clean, so I merged it to Linaro GCC 4.6. The test results for lp:675347 on 4.5 had problems though, but they might be unrelated to the patch. The test results for the "discourage NEON on A8" patch had similar failures, and that's a 4.6 testsuite. Richard Earnshaw approved the Thumb register allocation patch. I've committed it upstream, and updated the patch trackers. It was already on the Linaro 4.6 branch. Now that GCC 4.6 is released, switched all the Linaro tracking tickets from 'Fix committed' to 'Fix released'. Merged from FSF 4.5 to Linaro 4.5 and submitted the patch for test. The tests came back clean, so I pushed it to the 4.5 branch. (Yay for Michael's new test service!) Merged more patches from SG++ to Linaro. Or, at least considered them for merge. Mostly I decided that they were not appropriate for Linaro, at least, not just yet. I have yet to push these patches to Launchpad. Reviewed Richard Sandiford's patch for LP:714921. Retried the Android build with a view to integrating Android support in Linaro GCC 4.5 (4.6 should already support it). Eventually, after downloading many different git repositories and branches, and maxing out the memory on my machine a few times, I managed a successful build using the toolchain the Android team are using. I then backported Maxim's patches to Linaro GCC 4.5, and built and tested that, and got another successful Android build. I've pushed the patched toolchain to Launchpad at lp:~ams-codesourcery/gcc-linaro/android for testing. All being well, I'll merge Android support into the 4.5 trunk in time for the next release. ---- Upstream patched requiring review: * Thumb2 constants: http://gcc.gnu.org/ml/gcc-patches/2010-12/msg00652.html * ARM EABI half-precision functions http://gcc.gnu.org/ml/gcc-patches/2011-02/msg00874.html * NEON scheduling patch http://gcc.gnu.org/ml/gcc-patches/2011-02/msg01431.html

- Back from holiday, short week. == Porting jam == * We seem to have picked up a lot of ftbfs in the last couple of weeks - which is unfortunate because it may well be too close to the Natty release to do anything about them * Bug 745843 is a repeatable segfault in part of the build process of a package called vtk that is used by a few other things ; I've got this down to a particular call of one function - although gdb is getting rather confused (r0 & r1 changing as I single step across a branch) * Bug 745861 petsc build failure; I'm getting one of two different link errors depending which mood it is in - mpi related? * Bug 745873 - a meta package that just didn't have a list of packages to build with for armel; easy to do a simple fix (provided branch that built) for but the maintainer says it's too late for natty anyway and some more thought is needed. == Other == * Reading over some optimisation documents * Tested weekly release on Beagle-c4 (still no OTG usb and hence no networking for me) * Also simple boot test on panda; not much time for more thorough test. (seems to work) Dave

RAG: Red: Amber: Green: Current Milestones: | Planned | Estimate | Actual | qemu-linaro 2011-04 | 2011-04-21 | 2011-04-21 | | Historical Milestones: finish qemu-cont-integration | 2011-01-25 | 2011-01-25 | handed off | first qemu-linaro release | 2011-02-08 | 2011-02-08 | 2011-02-08 | qemu-linaro 2011-03 | 2011-03-08 | 2011-03-08 | 2011-03-08 | == maintain-beagle-models == * I spent a couple of days on initial cleanup of the omap3 patchstack in qemu-linaro. It's still some way from being upstreamable but at least now every patch in the stack compiles; this should make rebasing on upstream a bit less painful. * the board-ram-limits patchset is still stalled with upstream :-( == merge-correctness-fixes == * Aurelien applied lots of patches so the pipeline has drained again * cleaning up/reworking patches which fix handling of Neon UNDEF cases. Not very exciting but it will get a large set of patches out of the qemu-linaro patchstack. == other == * meetings: toolchain, standup Current qemu patch status is tracked here: https://wiki.linaro.org/PeterMaydell/QemuPatchStatus Absences: Holiday: 22 Apr - 2 May 9-13 May: UDS, Budapest (maybe) 15-16 August: QEMU/KVM strand at LinuxCon NA, Vancouver [LinuxCon proper follows on 17-19th]

New porter boxes

by Michael Hope

Hi there. The new porter boxes are now available for use. See: https://wiki.linaro.org/WorkingGroups/ToolChain/Hardware for details. These are PandaBoards with 768 MB of memory, a USB HDD, and a good internet connection. They can be used for day to day jobs like building programs, triaging bugs, and running benchmarks. Use dchroot natty to switch into the chroot. Use sudo apt-get install yyy to install packages. The build dependences for GCC, GDB, and binutils should already be installed. -- Michael
