This makes no sense to me

If I think about asm:

function1:

    (do stuff)

    jp function1

    ret

function2:

    (other stuff)

    ret

main:

    call function1

    call function2

the 2nd call might happen internally due to branch prediction but in practice it shouldn't and the processor fixes this

Oh yeah and TFA also goes with:

> The funny bit is that C got this right.(...) but C included one more rule: loops whose controlling expression is a constant expression may not be assumed to terminate.

Well, duh! A broken clock is right twice a day it seems

With UB the compiler has no particular requirement to emit the 'ret'. (or, in the example, anything at all for the function)
