== Progress == * Welcomed Kugan to the team working on GCC * Welcomed James Elliott to the team as project manager * Found Cortex-A9 bootstrapping issue raised as PR56184 * Fixed build issues in GCC and GDB. * Patch reviews. == Next week == * Investigate PR56184 further. == Future == * Run HOT/COLD partitioning benchmarks * Analyse ARM results * On x86_64 to see what the actual benefit we could get * fix-gcc-multiarch-testing * Come up with strawman proposal for updating testsuite to handle testing with varying command-line options. -- Matthew Gretton-Dann Toolchain Working Group, Linaro ___ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-toolchain
[ACTIVITY] 4-8 Feb 2013
== Progress == * Buildbots - Setting up Chromebook with a buildbot - http://llvm.org/viewvc/llvm-project?view=revision&revision=174421 - http://lab.llvm.org:8011/builders/clang-native-arm-cortex-a15 - 1h25min builds (3x faster than Pandas) * LAVA - Trying LLVM builds on Arndale - GCC segfaults: - "The bug is not reproducible, so it is likely a hardware or OS problem." * Distributed Panda - Setting up the boards, getting distcc on them - Speedup is squat (1.9%) because of too many parallel linking - Need to add LD to a group with less resources on Ninja * Vectorization - Reviewing some patches, discussing implementation details - Vectorization vs. O3 speedup: 2.5x ~ 3.0x (on both ARM and x86_64) - Working on global structure alias analysis * LLVM - Campaigning for integrates-as to be turned on by defaultfor ARM - ARM seems interested in fixing the eventual bugs - Adding 'armv7l' triple to default to 'cortex-a8' - http://llvm.org/viewvc/llvm-project?view=revision&revision=174466 - Campaining for buildbots to use CMAke/Ninja * EuroLLVM - Followup meeting, securing funding == Plan == * Change buildbots to not "make clean", try cmake * Try to reduce parallel linking flood, try one more panda * Continue with global structure alias analysis * Try to setup a test-suite buildbot ___ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-toolchain
[ACTIVITY] report week 6
Progress: * Linaro's KVM/QEMU mini-summit, aimed at summarising current status, identifying what needs to be done and what Linaro should be doing: https://wiki.linaro.org/LEG/Engineering/Virtualization/201302MiniSummit * implemented support for variable-length qdev array properties in QEMU and sent out patch for this plus vexpress fixes which use it * investigated how to run the Linux Test Project syscall tests under QEMU to improve the quality of our linux-user mode testing (wrote up a howto for the QEMU wiki: http://wiki.qemu.org/Testing/LTP many thanks to fabo for whipping up a Jenkins job to run these nightly) * couple of trivial linux-user patches as example low-hanging fruit revealed by the LTP test results -- PMM ___ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-toolchain
