Measuring performance of binary code layout

Question

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?[1] https://www.youtube.com/watch?v=r-TLSBdHe1A (relevant part starts at 10:00)

Is the actual constraint on your actual application actually CPU cycles?
Most applications are constrained by IO, network properties, or humans in the loop.
And most of those work well enough anyway.
Good luck.
