--- Comment #16 from PeteVine <tulipawn at gmail dot com> --- Also, I'd like to repeat the fact using -mcpu=cortex-a7 fixes the issue (no library calls present). Incidentally, having run that A7 profiled binary on a Cortex-A53, I'm seeing a 10% hit compared to a vanilla A7 binary. Hopefully that's just an artifact of profiling a different CPU architecture.
