Thanks,
Why would I use flto with a single file at the first place ?

Hello,
My question is purely theorical : what are the eventual disadvantages of putting a lot of functions in the same main.c file instead of spanning them into multiple static libraries ?
How will gcc sort this out ?
This question is neither related to maintainability, nor readability, nor executable size, nor ram usage.
Just performance.
Will the code units play a role or something ? Or whatever I don't think of ?
Will the perf will be the same ?
Thanks,
