--- Comment #6 from gnzlbg <gonzalo.gadeschi at gmail dot com> --- Thanks for all the quick feedback! > Also clang does not even document __builtin_ctzs anywhere ... This builtin is documented in the list of clang bultins. You can find it by using CTRL+F for the builtin, in that list, https://clang.llvm.org/docs/LanguageExtensions.html, which is the first link that Google reveals when searching for this exact builtin. Hope that helps. > ok, and? There is an HPC QCD app that was developed mostly using clang, and for which we can't apply source code modifications, that we'd like to compile which GCC as is, but currently doesn't due to this issue. Does that make sense? > You could just do: Thanks for the workaround! We were already using something similar as a temporary stopgap, but can't use that forever. Hope that makes sense! Thanks!
