Hello, (I'm working on 32-bit arm in case it matters.) There's an obvious optimization, when a function ends with a function call, to issue a jump instead of a call. Thus, upon return from the leaf function, we avoid a return instruction. My problem is that this optimization breaks tools that print function back traces :-) I would guess the optimization is enabled by -foptimize-sibling-calls So -fno-optimize-sibling-calls would disable it? Regards.
