What is the current state of things regarding binary code layout optimization?
I've watched a talk [1] on the Coz profiler, that asserted that code layout changes can have significant impact on performance.
My concrete questions:
- Are there recent (>2019) studies or papers discussing the effect of code layout on performance?
- Which tools can I use to inspect and alter code layout? Do I pass some flags to a linker or is there a specialized application for it?

Most applications are constrained by IO, network properties, or humans in the loop.
And most of those work well enough anyway.
Good luck.
