* 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
