I think your times are messed up because f3 and f2 produce the same asm

No: my times are OK.
You missed the fact that f2 and f3 (and, for that matter, f1) are inlined:
it does not matter that the out-of-line versions of f2 and f3 have the same
asm.

What times are you getting?

And what about the difference between the out-of-line versions of f1 and f2?
All the best,

Roberto
