Storing optimization choices in an ELF section

[Ludovic Courtès]

Hello,

A proprietary compiler stores information about optimizations it has
made (loop unrolling, vectorization, etc.) in a ‘.debug_opt_report’ ELF
section.  This information can later be exploited by performance
analysis tools, which can help understand performance.

Has there been any thought on implementing something similar in GCC?

Thanks,
Ludo’.
