The reason why this was not fixed until r16-101-g132d01d96ea9d6 is because the call is from main which is known to be called once and was not a candidate for IPA-CP until then. In fact renaming the function from main to f (and adding a `return 0` so not invoking undefined behavior), the scan-ipa-dump works all the way back to GCC 5.
