* Benchmarking of simple package builds with various string routine versions; not finding enough difference in the noise to make any large conclusions * Looking at the string routine behaviour with perf to see where the time is going - getting hit by the Linaro kernels on silverbell missing Perf enablement in the config - Useful amount of time does seem to be spent outside the main 'fast aligned' chunks of code - pushing/popping registers does seem to be pretty expensive * Started looking at libffi and hard float - Started writing a spec https://wiki.linaro.org/WorkingGroups/ToolChain/Specs/LibFFI-variadic - It's going to need an API change to libffi, although the change shouldn't break any existing code on existing platforms where they work. * Helping with the image testing
