AutoFDO - recent improvements
I will discuss recent progress on AutoFDO. This feature was originally contributed by Google in 2014 and allows to use of profiles generated by low-overhead profiling (perf) to guide optimisation. I will discuss work needed to make AutoFDO to cooperate with link-time optimisation and the changes needed to modernise the infrastructure for the current GCC.
