Hi,

* got llvm+clang working on ARM: https://wiki.linaro.org/KenWerner/Sandbox/HowToBuildToolchainComponents#llvm... * checked whether llvm inlines the __sync_* builtins on ARM or not: https://wiki.linaro.org/WorkingGroups/ToolChain/AtomicMemoryOperations#LLVM * developed a patch for #681138 (tested with current gcc-linaro) * spent some time for bootstrapping the GCC trunk in order to test and post that patch on the ml but wasn't successful (finally ran into the issues discussed at #659713) * did some verification work on #674090 * preparing to work on the "investigate current developer tools" item

Regards Ken
