--- Comment #11 from Jörn Engel <joern at purestorage dot com> --- I stand corrected. Thank you very much! Out of curiosity, if the only non-broken way to call __builtin_ctz(foo) is via "foo ? __builtin_ctz(foo) : 32", why isn't the conditional moved into __builtin_ctz()? Is there some hidden advantage from callers having to add the conditional or getting surprised by undefined behaviour?
