[ACTIVITY] Week 3
== Progress == * Buildbots - Odroid U2 died after a few days on USB stick, too. (I guess we're stuck with Chromebooks) - Upgrading chromebooks (to Saucy) due to a new GCC/libstdc++ 4.7+ restriction - Shuffling chromebooks, we now have three buildbots: - llvm-chrome-01: quick-build+check - llvm-chrome-02: self-host+check - llvm-chrome-03: test-suite * MCJIT Remote - Re-factored the communication protocol of MCJIT for remote processes - Still seeing one random failure on ARM, investigating * Compiler-rt - Investigating how to get it compiling all libraries and sanitizers on ARM * Background - Patch reviews, especially IAS and EH * Time - CARD-862 8/10 - Others 2/10 == Plan == * Continue MCJIT and Compiler-RT investigations * Continue reviewing IAS and EH patches * Try to run the EH tests on the test-suite with the current changes ___ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-toolchain

This should match what we have in meta-linaro/dora, which is the linaro
2013.12 toolchain release.

== Progress == * Cbuildv2 fix for *_release() functions which were changing out of the build directory but then not changing back to the builddir, which caused problems with paths relative to the builddir. (1/10) * TCWG-340 Enable Glibc remote testsuite integration - (7/10) - Working with upstream community on scoping and designing remote testsuite integration. - Setting up arm chroot environment on chromebook with documentation on how to make this reproduceable. * TCWG-352 AArch64 clone is missing some CFI markup - (2/10) - Setup aarch64 environment for testing and built static clone tests to test the patch. == Plan == * Start implementing (code) for glibc remote testsuite integration. == Issues == None ___ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-toolchain
