As another data point, I have collected compile-time numbers for ARM64 with -Os
-g LTO & -Oz -g LTO. Geoman changes below. Compile time here is actual
execution time on a stabilized system.
Compile time code size
-Oz RLTO 0.67% -0.12%
-Os -g RLTO 0.06% -0.14%
I think flipping the switch now should be reasonable compile-time wise and we
also have some ideas on how to reduce compile-time even further once it is
enabled by default.
