--- Comment #14 from Francois-Xavier Coudert <fxcoudert at gcc dot gnu.org> --- (In reply to rguent...@suse.de from comment #12) > So I bet apple GCC 4.2 is affected as well - not sure if LLVM > provides libgcc_s on newer systems. Apple does not provide GCC 4.2 anymore, but its LLVM compiler provides a __addvsi3 as part of its libSystem. Probably for backward compatibility, because… (In reply to rguent...@suse.de from comment #13) > Simply get libcompiler_rt folks to fix their code?

So, I cannot get a simple reproducer to report to them.
